Quartz sand bucket elevator

Product introduction

Quartz sand Bucket elevator purpose
  Bucket elevator is a kind of mechanical conveying equipment with fixed device. It is efficient, energy-saving, well sealed and pollution-free. It is mainly suitable for continuous vertical lifting of powdery, granular and small materials. It can be widely used in bulk in mines, chemical industry, metallurgy, feed plants, flour mills, rice mills, oil plants, starch plants, grain depots, port terminals and other large and medium-sized enterprises Promotion of materials.

Characteristics of quartz sand bucket elevator
1. The driving power is small, and the feeding, induced discharging and hopper dense layout with large capacity are adopted. When the material is lifted, there is almost no material return and excavation, so the invalid power is low.
2. With wide lifting range, this kind of elevator has less requirements on the types and characteristics of materials. It can not only lift the general powder and small granular materials, but also can lift the materials with higher grinding performance. It has good sealing performance and less environmental pollution.
3. Good operation reliability, advanced design principle and processing method ensure the reliability of the whole machine, and the fault free time is more than 20000 hours. High lifting height. The elevator runs smoothly, so it can reach a higher lifting height.
4. The service life is long, the feeding of the hoist adopts the inflow type, and there is no need to dig the material with a bucket, so there is little extrusion and collision between the materials. When the machine is designed, the material is less scattered during feeding and discharging, and the mechanical wear is reduced.

Working principle of quartz sand bucket elevator
The hopper scoops up the materials from the storage below, and with the conveyor belt or chain lifted to the top, it bypasses the top wheel and turns down to pour the material into the receiving tank. The transmission belt of belt transmission generally adopts rubber belt, which is installed on the lower or upper drive drum and the upper and lower steering roller. Chain drive is usually equipped with two parallel transmission chains. There is a pair of transmission chain wheels at the top or bottom and a pair of change direction chain wheels at the bottom or above. Generally, it is equipped with casing to prevent dust from flying in the material.


Precautions for use and maintenance
1. The hoist shall be maintained and managed by designated personnel, and the key of power switch box shall be managed by designated personnel.
2. The hoist must be equipped with winch limiter and travel limiter. The limiter shall make the pulley stop automatically when it is lifted to 300 mm away from the drum or pulley.
3. The hoist shall have the maximum load mark, and the weight shall not be overloaded (1t) during lifting and landing.
4. After power transmission, check the safety devices such as winch limiter, travel limiter, interlock switch, etc., which are sensitive and reliable, and carry out trial lifting.
5. Before lifting and landing, the car can only be started after ringing the alarm.
6. The hoist is not allowed to carry people up and down.
7. After the work is finished, the lifting plate of the hoist should fall to the ground, then cut off the power supply and close the upper and lower guardrail doors.  
8. Keep the environment around the elevator clean.
install
1. When installing the hoist, the base shall be fixed on a reliable foundation, and then the barrel shall be connected to the base in turn, and finally the head shall be connected with the reducer motor.
2. After the whole machine is installed and straightened, the barrel must be fixed with the floor at the place where it passes through the floor. If there is any attachment, the bracket supporting the casing shall be installed to prevent the whole machine from tilting and displacement.
3. Sealing gasket is allowed to be inserted into barrel connection to ensure sealing.
4. The hopper of the elevator is installed on the hopper belt according to the requirements, and the two ends of the hopper belt installed with the hopper are respectively put into the machine head. The head wheel and bottom wheel are connected at the early operation hole. When the hopper belt is installed. The bottom wheel should be adjusted to the highest position.
5. Align the head axle shaft to the horizontal level, and make the head axle shaft and tail axle shaft in a unified vertical plane.
6. The bucket elevator is a vertical conveying equipment. The center lines of head wheel, bottom wheel and barrel shall be on the same plumb line, and the deviation per meter length shall not exceed 2mm, and the accumulated deviation shall not exceed 8mm.
7. When the hopper is installed in the elevator, there should be no deflection to cause collision with the shell.
8. The tensioning device shall ensure that the hopper belt has the necessary tension force for normal operation.
9. After the hoist is installed, the lubricating oil shall be added to each lubricating part for no-load test run. After the no-load test run is normal, the loaded test run and production can be carried out.
