Description

Technical Field

[0001] The utility model relates to the field of elevator equipment, in particular to an anti-accumulation plate chain bucket elevator. Background Art

[0002] In cement production, cement raw materials need to be lifted by elevators. Bucket elevators are continuous conveying machines that use a series of buckets evenly fixed to endless traction components to lift materials vertically. Bucket elevators use a series of buckets fixed to traction chains or belts to transport bulk materials upward in a vertical or nearly vertical direction.

[0003] For example, the patent document with the announcement number CN213770144U discloses a bucket elevator for producing cement, which pours materials into the interior of the elevator shell through a feed hopper and continuously lifts the materials upward using a lifting mechanism. However, during the use of most bucket elevators, materials are easily spilled and fall to the bottom of the inner cavity of the bucket elevator, causing accumulation, and when the conveyed materials are replaced, different types of materials are easily mixed together. Utility Model Content

[0004] The purpose of the utility model is to provide a plate chain bucket elevator for preventing material accumulation in order to solve the above-mentioned problem.

[0006] A material accumulation prevention plate chain bucket elevator comprises a shell, a feed hopper is fixed on the front side of the shell, a lifting mechanism is arranged inside the shell, an arc plate is fixed inside the shell, the arc plate is located below the lifting mechanism, inclined material guide plates are fixed on the front and rear sides of the arc plate, an material accumulation prevention mechanism is arranged above the arc plate, the material accumulation prevention mechanism comprises a first rotating shaft, the first rotating shaft is rotatably installed in the shell, a first spiral plate is fixed on the first rotating shaft, a bulk material plate is fixed on the side of the first spiral plate, spikes are fixed on the bulk material plate, a plurality of abrasive mechanisms are arranged on the first rotating shaft, a return mechanism is arranged on one side of the shell, a discharge pipe is fixed on the side of the shell close to the return mechanism, the feed end of the discharge pipe is located at the connection between the arc plate and the shell, a transmission mechanism is arranged on one side of the shell, and the transmission mechanism is used to transmit the rotational power of the lifting mechanism to the first rotating shaft.

[0007] Preferably, the abrasive mechanism includes a guide cylinder fixed on the first rotating shaft, a slide rod is slidably connected in the guide cylinder, one end of the slide rod away from the first rotating shaft extends out of the guide cylinder and is fixedly connected to a friction plate, and one end of the first rotating shaft located in the guide cylinder is fixedly connected to a limiting plate.

[0008] Preferably, a friction pattern is provided on the side of the friction plate away from the slide rod, and a ball is movably embedded in the side of the limit plate, and the ball contacts the inner wall of the guide cylinder.

[0009] Preferably, the return material mechanism includes a return material cylinder, a second rotating shaft is rotatably installed in the return material cylinder, a second spiral plate is fixed on the second rotating shaft, a motor is fixed on the top of the return material cylinder, the output shaft of the motor is fixedly connected to the second rotating shaft, a return material pipe is fixedly connected to the side wall of the return material cylinder near the top, the discharge end of the return material pipe is located above the feed hopper, and the discharge end of the discharge pipe is connected to the bottom end of the return material cylinder.

[0012] The beneficial effect is that by setting the arc plate, the material in the shell falls on the arc plate after being spilled. When the lifting mechanism is working, the first rotating shaft and the first spiral plate are driven to rotate through the transmission mechanism. The first spiral plate gradually pushes the material on the arc plate to the discharge pipe and enters the return mechanism. The return mechanism puts the material back into the feed hopper, thereby avoiding the accumulation of materials at the bottom for a long time, and at the same time avoiding the mixing of multiple materials when the elevator lifts different materials. In addition, the bulk plate arranged on the first spiral plate can break up the agglomerated materials, avoid the block materials from focusing too much and causing the discharge pipe to be blocked, and reduce the possibility of material accumulation. At the same time, the abrasive mechanism on the first rotating shaft can make the agglomerated materials be broken up more fully and evenly.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The utility model is further described below in conjunction with the accompanying drawings:

A plurality of abrasive mechanisms are arranged on the first rotating shaft 501, and a return mechanism is arranged on one side of the shell 1. A discharge pipe 102 is fixed on the side of the shell 1 close to the return mechanism, and the feed end of the discharge pipe 102 is located at the connection between the arc plate 3 and the shell 1. A transmission mechanism is arranged on one side of the shell 1, and the transmission mechanism is used to transmit the rotational power of the lifting mechanism to the first rotating shaft 501.

[0026] The abrasive mechanism includes a guide cylinder 801, which is welded to the first rotating shaft 501. A slide rod 802 is slidably connected in the guide cylinder 801. One end of the slide rod 802 away from the first rotating shaft 501 extends out of the guide cylinder 801 and is fixedly connected to a friction plate 803. One end of the first rotating shaft 501 located in the guide cylinder 801 is fixedly connected to a limiting plate 804. When the guide cylinder 801 rotates to above the first rotating shaft 501, the slide rod 802 retracts into the guide cylinder 801 under the action of gravity. When the guide cylinder 801 rotates to below the first rotating shaft 501, the slide rod 802 extends out of the guide cylinder 801 under the action of gravity, so that the friction plate 803 generates a downward pressure on the material, breaks the agglomerated material, and through the friction between the friction plate 803 and the material, the agglomerated material is more fully broken.

[0027] Friction lines are arranged on the side of the friction plate 803 away from the slide bar 802 to improve the friction effect between the friction plate 803 and the material.

[0029] The lifting mechanism includes a power shaft 201 , which is installed in the housing 1 through a bearing. A transmission belt 202 is provided on the power shaft 201 , and a plurality of buckets 203 are installed on the transmission belt 202 .

The driving pulley 701 and the driven pulley 703 are connected via a belt 702 .

[0031] Working principle: When in use, the material is put into the feed hopper 101, and the transmission belt 202 drives the bucket 203 to move and lift the material. At the same time, the power shaft 201 drives the first rotating shaft 501 to rotate through the active pulley 701, the belt 702 and the driven pulley 703. The first rotating shaft 501 drives the first spiral plate 502 to rotate. The material spilled in the shell 1 falls on the arc plate 3, and the first spiral plate 502 pushes the material to move toward the discharge pipe 102. During this period, the bulk plate 503 rotates with the first spiral plate 502, and the agglomerated material is broken by the spikes 504. At the same time, the guide cylinder 801 rotates with the first rotating shaft 501. When the guide cylinder 801 rotates to the first rotating shaft 501, the material is crushed by the spikes 504. When the guide cylinder 801 is rotated to below the first rotating shaft 501, the slide bar 802 extends out of the guide cylinder 801 under the action of gravity, so that the friction plate 803 exerts a downward pressure on the material to break the agglomerated material, and the friction between the friction plate 803 and the material can more fully break the agglomerated material, and then the material enters the return cylinder 601 through the discharge pipe 102, the motor 604 drives the second rotating shaft 602 to rotate, the second rotating shaft 602 drives the second spiral plate 603 to rotate, the second spiral plate 603 lifts the material upward, and finally the material falls back into the feed hopper 101 through the return pipe 605.
