Description

Technical Field

[0001] This utility model relates to the field of mine filling technology, specifically to an anti-clogging paste thickener. Background Technology

[0002] Mine backfilling is a systematic engineering project that controls ground subsidence and ensures mining safety by filling goaf areas. Its core is to use backfill material to stabilize the goaf environment and improve resource utilization. In the process of mine backfilling, paste thickeners are needed to concentrate high-concentration solid-liquid mixtures such as slurry and tailings to meet backfilling standards and transport them to the goaf area for filling.

[0003] When using a paste thickener, because it is used to concentrate high-concentration solid-liquid mixtures such as slurry and tailings, the filling material inside the pipe is quite viscous during the transportation process. Sometimes it needs to be transported upwards, and the pipeline also has bends depending on the requirements. Therefore, when relying solely on rotating spiral blades for pumping, the filling material is prone to blockage at the bends, affecting the normal progress of mine filling. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the filling material inside the tube of the above-mentioned paste thickener is relatively viscous and sometimes needs to be transported upwards. In addition, the pipeline has bends as required, so the filling material is prone to blockage at the bends, which affects the normal filling process in the mine. This utility model provides an anti-blocking paste thickener.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A clog-resistant paste thickener includes a pump inlet pipe. A connecting cover is fixedly installed at the lower left end of the pump inlet pipe. A mounting cover is fixedly installed at the lower left end of the connecting cover. A turntable is rotatably connected to the lower left side of the mounting cover. An internal gear ring is fixedly connected to the outer periphery of the upper right end of the turntable. A gear one is rotatably connected to the upper part of the mounting cover, and the gear one meshes with the internal gear ring. A rotating shaft is rotatably connected to the center of the mounting cover. A gear two is fixedly installed to the outer periphery of the rotating shaft, and the gear two meshes with the gear one. A rotating roller is slidably connected to the outer periphery of the right side of the rotating shaft. A spring is fixedly connected to one end of the rotating shaft inside the rotating roller and to the inner wall of the rotating roller. A spiral blade is fixedly connected to the outer periphery of the rotating roller. A push plate is fixedly connected to the left side of the spiral blade on the outer periphery of the rotating roller. A bevel gear is rotatably connected to the bottom of the mounting cover. A bevel rack is fixedly connected to the right end of the bottom of the internal gear ring. The bevel rack and the bevel gear mesh with each other. A column is eccentrically fixedly installed at the top of the bevel gear. A limit ring is provided above the bevel gear. The column is slidably connected to the inside of the limit ring. A rotating ring is rotatably connected to the outer periphery of the left side of the rotating roller. A connecting rod is fixedly connected between the right end of the limit ring and the bottom end of the rotating ring.

[0007] Furthermore, the outer periphery of the center of the turntable protrudes outward, and the turntable is limited and rotated within the mounting cover by an annular protrusion.

[0008] Furthermore, the right side of the rotating shaft extends into the interior of the connecting cover, and the limiting sliding connection between the rotating shaft and the rotating roller is also located inside the connecting cover.

[0009] Furthermore, the outer periphery of both the helical blades and the pusher plate is attached to the inner wall of the pump inlet pipe. Therefore, the filling material inside the pump inlet pipe can be propelled by the rotation of the helical blades and the movement of the pusher plate.

[0010] Furthermore, the number of teeth on the bevel rack is half the number of teeth on the bevel gear. Therefore, during one rotation of the turntable, the bevel gear can be rotated by an angle of 180°.

[0011] Furthermore, the connecting rod passes through the inner wall of the right side of the mounting cover and is slidably connected to the mounting cover. The connecting rod can be moved by the cooperation of the column and the limiting ring.

[0012] Furthermore, a motor is fixedly installed at the center of the lower left end of the mounting cover, and the motor is connected to the turntable for transmission, thereby driving the turntable to rotate.

[0013] Furthermore, a delivery pipe is fixedly connected to the top of the lower side of the pump inlet pipe, and the connection between the delivery pipe and the pump inlet pipe is located on the upper right side of the push plate, thereby delivering the concentrated filling material into the interior of the pump inlet pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes the cooperation between the bevel rack and bevel gear at the bottom of the turntable to rotate and ultimately drive the spiral blades to rotate, thereby pushing the filling material. At the same time, the cooperation between the column and the limiting ring allows the connecting rod to intermittently push the rotating roller and the spiral blades to move. This achieves the simultaneous advancement of the filling material through the rotating spiral blades and the intermittent direct advancement of the filling material, thus avoiding blockage of the filling material and ensuring the normal progress of mine filling.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] A preferred embodiment of the present invention, an anti-clogging paste thickener, will be described in detail below, such as... Figures 1-8 As shown, an anti-clogging paste thickener includes a pump inlet pipe 1, a connecting cover 2 fixedly installed at the lower left end of the pump inlet pipe 1, and an installation cover 3 fixedly installed at the lower left end of the connecting cover 2. A turntable 4 is rotatably connected to the lower left side inside the installation cover 3. The outer periphery of the middle part of the turntable 4 protrudes outward, and the turntable 4 is rotatably connected to the installation cover 3 through the annular protrusion.

[0027] An internal gear ring 5 is fixedly connected to the upper right periphery of the turntable 4. A gear 6 is rotatably connected to the upper limit inside the mounting cover 3, and the gear 6 meshes with the internal gear ring 5. A rotating shaft 7 is rotatably connected to the center inside the mounting cover 3. A gear 8 is fixedly installed on the periphery of the rotating shaft 7, and the gear 8 meshes with the gear 6. A rotating roller 9 is slidably connected to the right periphery of the rotating shaft 7. The right side of the rotating shaft 7 extends into the interior of the connecting cover 2, and the slidable connection between the rotating shaft 7 and the rotating roller 9 is also located inside the connecting cover 2. A spring 71 is fixedly connected between the end of the rotating shaft 7 inside the rotating roller 9 and the inner wall of the rotating roller 9. A spiral blade 10 is fixedly connected to the periphery of the rotating roller 9. A push plate 11 is fixedly connected to the left side of the spiral blade 10 on the periphery of the rotating roller 9. The peripheries of the spiral blade 10 and the push plate 11 are attached to the inner wall of the pump inlet pipe 1. Therefore, the filling material inside the pump inlet pipe 1 can be pushed forward by the rotation of the spiral blade 10 and the movement of the push plate 11.

[0028] Inside the mounting cover 3, a bevel gear 12 is rotatably connected to the bottom limit. A bevel rack 13 is fixedly connected to the right end of the bottom of the internal gear ring 5. The bevel rack 13 and the bevel gear 12 mesh with each other. The number of teeth of the bevel rack 13 is half the number of teeth of the bevel gear 12. Therefore, during the rotation of the turntable 4, the bevel gear 12 can be rotated by an angle of 180°.

[0029] A column 14 is eccentrically fixed to the top of the bevel gear 12. A limit ring 15 is provided above the bevel gear 12. The column 14 is slidably connected to the inside of the limit ring 15. A rotating ring 16 is rotatably connected to the outer side of the left side of the roller 9. A connecting rod 17 is fixedly connected between the right end of the limit ring 15 and the bottom end of the rotating ring 16. The connecting rod 17 passes through the inner wall of the right side of the mounting cover 3 and is slidably connected to the mounting cover 3. The connecting rod 17 can be moved by the cooperation of the column 14 and the limit ring 15.

[0030] A motor 18 is fixedly installed at the center of the lower left end of the mounting cover 3, and the motor 18 is connected to the turntable 4 for transmission, thereby driving the turntable 4 to rotate.

[0031] A delivery pipe 19 is fixedly connected to the top of the lower side of the pump inlet pipe 1, and the connection between the delivery pipe 19 and the pump inlet pipe 1 is located on the upper right side of the push plate 11, thereby delivering the concentrated filling material into the interior of the pump inlet pipe 1.

[0032] The working principle of this utility model is as follows:

[0033] In use, the concentrated filling material is introduced into the pump inlet pipe 1 through the connection of the delivery pipe 19. Then, the motor 18 is started to drive the turntable 4 to rotate. During the rotation of the turntable 4, the meshing between the internal gear ring 5 on the side end of the turntable 4 and the gear 6, as well as the meshing between the gear 6 and the gear 8, drives the gear 8 to rotate. This causes the gear 8 to drive the rotating shaft 7 to rotate. The rotating shaft 7 is connected to the roller 9 to limit the rotation of the roller 9 and the spiral blade 10 inside the pump inlet pipe 1, thereby pushing the filling material introduced into the pump inlet pipe 1 to achieve the conveying of the filling material.

[0034] During the rotation of turntable 4, the meshing of the bevel rack 13 at the bottom of turntable 4 with the bevel gear 12, and the design that the number of teeth of the bevel rack 13 is half the number of teeth of the bevel gear 12, can drive the bevel gear 12 to rotate 180°. During the rotation of bevel gear 12, the cooperation between the eccentric column 14 at the top of bevel gear 12 and the limiting ring 15 can drive the limiting ring 15 to move to the upper right. Through the design of the connecting rod 17 between the limiting ring 15 and the rotating ring 16, and the limiting rotation connection of the rotating ring 16 on the periphery of the rotating roller 9, the tension spring 71 of the rotating roller 9 can be pushed to move to the upper right. Then, under the action of the push plate 11 and the spiral blade 10, the filling material inside the pump inlet pipe 1 can be pushed directly to the upper right, making it easier for the viscous filling material to pass through bends and easily blocked places, thus avoiding the blockage of the filling material during the conveying process.

[0035] After the bevel rack 13 stops meshing with the bevel gear 12, the roller 9 will return to its initial position to the lower left under the restoring force of the spring 71, and will be pushed to the upper right again after the next meshing. This achieves the simultaneous advancement of the filling material through the rotating helical blades 10 and the intermittent direct advancement of the filling material, thereby avoiding blockage of the filling material and ensuring the normal progress of mine filling.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
