 Advantages of DT Ⅱ belt conveyor

working principle

       DT2 Type II Belt conveyor It is mainly composed of frame, conveyor belt, belt roller, tensioning device, transmission device, etc. The fuselage is made of high-quality steel plate, and the frame is formed by the height difference between the front and rear legs, and the plane is inclined at a certain angle. The rack is equipped with belt roller, idler, etc., which is used to drive and support the conveyor belt. There are two ways to drive the reducer motor and the electric roller.

 DT Ⅱ belt conveyor
 
          DT2 Type II Belt conveyor The conveyor belt is a continuous mechanical component. The conveyor belt forms a closed loop around the transmission drum and the diversion drum. The bearing and return branches of the conveyor belt are supported on the roller, and the tension device gives appropriate tension force. During the work, the belt is driven by the friction force between the transmission drum and the conveyor belt. The material is unloaded at the receiving device by the unloading device or transported to the drum with the conveyor belt to complete the conveying work.

technical requirement
 
1. The longer the horizontal conveyor belt, the higher the belt speed; the larger the inclination angle of the belt, the shorter the conveying distance, the lower the belt speed.
2. The preferred conveyor belt speed should not exceed 0.3m/s.
3. When plough unloader is used, the belt speed should not exceed 2m / s.
4. The equipment is often used for large output and high power occasions. When the conveying capacity is large and the conveyor belt is wide, the belt speed should be higher.
 
 Parameters of DT Ⅱ belt conveyor

Features of accessories

Reducer

DBY (two-stage) and DCY (three-stage) conical cylindrical hardened gear reducer is adopted, which has the characteristics of large bearing capacity, high efficiency, light weight and long service life. The input shaft and output shaft are arranged in vertical direction, which can reduce the floor area of driving station. The working environment temperature of reducer is - 40 ℃ ~ + 45 ℃. When the ambient temperature is lower than 0 ℃, the lubricating oil should be heated to + 10 ℃ before starting and put into operation. Oil pool splash lubrication and natural cooling shall be adopted for reducer. Circulating oil lubrication or additional cooling device shall be used when thermal power is unbalanced.

 DT Ⅱ belt conveyor accessories
 
Brake

Ywz5 series hydraulic push rod brake is selected in this series, which has the advantages of fast working frequency, stable braking, adjustable braking torque, easy replacement of friction pad and long service life. The protection grade is IP65 and the working frequency of hydraulic push rod is 100%.

 Features of DT Ⅱ belt conveyor
 
bend pulley

It is used to change the running direction of the conveyor belt or to increase the surrounding angle of the belt on the driving drum. Its structural form is the same as that of the transmission drum, which is divided into three types: light, medium and heavy. The grading diameter of the shaft is 50 ~ 100 mm, 120 ~ 180 mm, and 200 ~ 260 mm. There are two kinds of bare steel surface and smooth rubber surface on the drum surface.

 DT Ⅱ belt conveyor reducer
 
Funnel head
 
The head hopper is an auxiliary device of belt conveyor, which is used to transfer and store materials
1. The funnel and the shield are designed as a whole, collectively referred to as the head funnel
2. Due to the different process layout of belt conveyor, material type and transfer direction are changed, only the upper part of funnel is designed in this series, and flange interface is reserved, so that the design department can complete the material transfer design of the lower part of the funnel according to the specific situation.
3. Structural form:
Common type: used for belt conveyor with belt width of 500 mm, 600 mm, loose density and particle size of materials are small
Lining plate type: replaceable wear-resistant lining plates are installed on both sides and front of the funnel.
4. According to different belt speed, there are two specifications, the first is v = 0.8 ~ 2.5m/s, the second is v = 3.15m/s.
5. The sweeper is placed inside the funnel, and the material swept can enter the funnel directly.
6. Dust proof rubber curtain was adopted

Product maintenance

1. Under normal conditions, DT Type belt conveyor requires no-load start and avoid frequent start-up in a short time.
2. Always check the reducer for oil leakage, and regularly check whether the oil charge is appropriate, and supplement it in time.
3. Keep the surrounding area of the conveyor, especially the driving device, clean up the pulverized coal and sundries on and around the conveyor in time to avoid affecting the normal operation.
4. The idlers with inflexible rotation should be replaced and repaired in time.
5. The driving drum should be kept clean, and the adhesion and moisture should be removed in time.
6. If the belt deviation is found, it should be adjusted in time, and it is not allowed to wear the belt edge.
7. The adhesive tape joint shall be inspected frequently, and the damage shall be repaired in time to prevent water from penetrating into the core of the tape.
8. Check the outlet of the material to prevent it from being broken or broken.
 
 Maintenance of DT Ⅱ belt conveyor
 
Variable frequency drive control technology
 
DT Ⅱ belt conveyor adopts frequency conversion control drive mode, which can easily realize stable starting and adjustable starting time, and greatly reduce the impact of motor starting on power grid. Because the variable frequency starting can start with load, it has the advantages of frequent heavy load starting and braking, frequent cabin changing and small flow feeding; and the frequency conversion starting has no limit on the starting frequency, so it can be adjusted in the process of operation. In addition, the frequency conversion speed regulation also has the advantages of energy saving.
 
 Improvement of DT Ⅱ belt conveyor
 
Safety protection and monitoring device
 
The following monitoring devices can be selected according to the process and working conditions of single machine or conveyor system.
1) The belt deviation monitoring is installed at the winding in point of the conveyor belt on both sides of the conveyor or the position to be monitored. When the slight deviation reaches 5% of the belt width, it will send out a signal and give an alarm. When the severe deviation is 10% bandwidth, delay action, alarm and stop.
2) Slip monitoring: used to monitor the linear speed difference between the transmission drum and the conveyor belt. If the allowable value is exceeded, the alarm will be given and the conveyor belt will be automatically tensioned or shut down.
3) Over speed monitoring: it is used for the conveyor under cloud or downward transportation conditions. When the belt speed reaches 115% ~ 125%, the alarm and emergency stop will be given.
4) Pull rope switch is used for emergency stop along the line. A group of switches are installed on both sides of the frame and along the full length of the conveyor, not separated by 60m. After alarm and self-locking.
5) Other signals include silo blocking signal, longitudinal tearing signal, tension brake signal, temperature measurement signal, etc., which can be selected according to the needs and installed and debugged according to the general design drawing and the operation manual provided by the manufacturer.

 Oil leakage of DT Ⅱ belt conveyor
 
Improved belt conveyor
 
At present, the new standard DT Ⅱ (a) belt conveyor has been improved on the basis of DT Ⅱ belt conveyor. All of them are national standards. They are designed according to different design manuals, but there are some differences. Compared with DTII type, DT Ⅱ (a) is more reasonable. The size of type II and type DT (II) is more light than that of type DT (a).
