Description

Chain bucket inclined discharging hoister

Technical Field

The invention relates to a chain bucket inclined discharging hoister which can be widely applied to continuously and vertically conveying powdery, granular or small blocky materials, and is particularly applied to conveying materials with lower density, smaller grain diameter and certain viscosity.

Background

The bucket elevator is material vertical conveying equipment, adopts the hopper to load the material, promotes the material to a take the altitude, and the hopper changes direction to the gyration through carrying out the return stroke behind the drive sprocket, and the material relies on centrifugal force or gravity to unload to the discharge opening. Present bucket elevator, return chain and hopper and casing wallboard parallel arrangement, during the hopper uninstallation, the material can lead to the material can't be shed to the discharge opening position completely because of centrifugal force is not enough, and partial material can leak to chassis bottom along the clearance between hopper and the casing, appears serious material returning problem. The returned materials can be accumulated at the bottom of the shell of the bucket elevator, so that the conveying efficiency of the bucket elevator is reduced, the load of a motor is increased, the abrasion of a chain hopper is accelerated, and even the chain hopper is blocked, so that the bucket elevator is blocked or stopped. At present, bucket elevator is in order to prevent the returning charge, and the discharge opening increases the flexibility and connects the flitch, nevertheless connects the flitch wearing and tearing fast, maintains the trouble, and to the material that density is low, the particle diameter is less, have certain viscidity, still can't avoid the returning charge and pile up the chassis bottom problem.

The invention relates to a chain bucket inclined discharging hoister, wherein a through cover and a blank cover are used as end covers of bearing seats. The main differences between the two are: (1) The assembly positions are different, the transparent cover is arranged at one end of the bearing seat passing through the shaft, and the blank cover is arranged at the end of the bearing seat not passing through the shaft. (2) the action principles are different: the through cover is used for allowing the shaft to pass through the hole in the middle, and the blank cover is used for preventing the shaft from passing through the middle. The two are mainly used for axial positioning, dust prevention and sealing of the bearing outer ring, and can be matched with a sealing piece to achieve the sealing effect besides the dust prevention and sealing.

The invention relates to a chain bucket inclined discharging hoister, which has the working principle that: equipment hopper is when loading material, and inside the material slided into the casing along the swash plate of slope feed inlet, leaned on inertia to shed to the hopper in, because of it was lower to shed speed, the overwhelming majority material can get into the hopper, and the gap that very little material can be followed between casing and the hopper falls into bottom of the case, is taken away by the hopper that is changing direction afterwards. The material is poured into the inclined discharge opening after bypassing the dragging chain wheel and turning downwards along with the dragging chain lifted to the top. The hopper is dragged and lifted by the dragging chain wheel, the hopper is returned to change direction and rotate back after passing through the chain wheel, and the direction is changed by the action of the pressing wheel and dragging chains on two sides of the hopper. The chain inclined type discharging structure is adopted, when the return stroke of the chain hopper is changed, the hopper is completely overturned, and when materials vertically fall from the inside of the hopper by virtue of gravity, the materials can completely fall into the inclined discharging opening and are discharged along the inclined discharging opening. In the whole unloading process, no material returns to the bottom of the equipment shell. The invention is suitable for the working conditions of materials with lower material density, smaller particle size and certain viscosity.

The chain bucket inclined discharging hoister is characterized in that the pressing wheel is used for returning direction change and inclined discharging of the hopper, and during the downward discharging process of the hopper, all materials in the hopper enter the inclined discharging opening by virtue of centrifugal force or gravity, so that no material leaks to the bottom of a machine shell, namely, no material returning phenomenon exists, the operation is reliable, the material conveying is smooth, and the conveying efficiency is high.

The chain bucket inclined discharging hoister disclosed by the invention is used for vertically hoisting and occupies a small area. And no material return is caused in the unloading process, so that the unloading efficiency is high. Because no material is accumulated at the bottom of the machine shell, the mechanical abrasion is reduced, the equipment abrasion is low, and the service life is long. And because the material conveying of the dragging chain is not influenced, the pulling force borne by the dragging chain is reduced, the motor load is small, the driving power is small, the power consumption is low, the conveying capacity is large, the energy consumption is low, and the energy is saved.

According to the chain bucket inclined discharging hoister, the two pressing wheels are arranged on two sides of the machine shell and are symmetrically arranged, the mounting heights and positions are symmetrical, stable operation of equipment is guaranteed, and the higher hoisting height can be achieved.

According to the chain bucket inclined discharging hoister, the pressing wheel is subjected to surface hardening treatment and can be disassembled and replaced after being worn, and the service life of equipment is long.

The chain bucket inclined discharging elevator disclosed by the invention adopts a closed shell structure, is good in sealing performance, avoids flying dust, is less in environmental pollution and is environment-friendly.

In conclusion, the chain bucket inclined discharging hoister has the advantages of no material return, reliable operation, smooth material conveying, high conveying efficiency, high discharging efficiency, low equipment abrasion, small driving power, low power consumption, high conveying capacity, energy conservation, long service life of equipment and environmental protection.
