Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, and in particular to a feeding device for a paste pipeline cleaning ball. Background Technology

[0002] The gangue paste filling uses coal gangue as the main raw material, mixed with a certain amount of fly ash and cementing materials, and water to prepare the filling paste. The paste filling material is transported through pipelines to the underground filling plant for subsequent pouring. Since the paste filling material contains cementing materials, after filling, in order to prevent the residual paste in the pipeline from solidifying, it is necessary to insert silicone cleaning balls to clean the pipeline.

[0003] The procedure for using a cleaning ball to clean a pipeline is as follows: a cleaning ball is placed inside the pipeline, and compressed air is used to push the cleaning ball from the beginning to the end of the pipeline. The interference fit between the pipeline and the cleaning ball is used to clean the residual slurry inside the pipeline.

[0004] Most existing pipe cleaning devices require manual placement of cleaning balls, resulting in low cleaning efficiency. Summary of the Invention

[0005] To address the issue that existing pipeline cleaning devices mostly require manual placement of cleaning balls, which reduces pipeline cleaning efficiency, this device uses a ball-feeding mechanism to transport multiple cleaning balls one by one from the hopper to the feeding pipe, enabling continuous conveying of cleaning balls and improving the cleaning efficiency of paste pipelines.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A feeding device for cleaning balls in a paste pipeline includes a feeding pipe connected to the paste pipeline, a valve on the feeding pipe, and a hopper connected to the upper side of the feeding pipe. The valve is located between the paste pipeline and the hopper. Multiple cleaning balls are arranged sequentially from top to bottom in the hopper. A ball feeding mechanism is also provided on one side of the hopper. The ball feeding mechanism includes a first limiting plate, a second limiting plate, a rack, and a gear. The first limiting plate is located above the second limiting plate. Racks are provided on opposite sides of both the first and second limiting plates. The gear is located between the first and second limiting plates. The first and second limiting plates are arranged opposite each other and mesh with the racks to achieve mutual approach or distance when the gears rotate. The first and second limiting plates are respectively set on the upper and lower sides of the bottom cleaning ball. The end of the first limiting plate extends into the inner wall of the hopper and is flush with the inner wall of the hopper. The end of the second limiting plate extends into the interior of the hopper and contacts the bottom cleaning ball. The end of the feeding pipe is provided with a telescopic mechanism, which is used to transport the cleaning ball falling into the feeding pipe to the paste pipe.

[0008] Furthermore, it also includes a support, the feeding pipe is fixedly installed on the side wall of the support, and the upper end of the hopper extends out of the upper cover plate of the support.

[0009] Furthermore, a box is provided on one side of the hopper, and the ball feeding mechanism is disposed in the box. The first limiting plate and the second limiting plate are both slidably disposed on the inner side wall of the box. The ball feeding mechanism also includes a rotating shaft, which is fixedly mounted on a gear. One end of the rotating shaft is rotatably connected to the inner side wall of the box, and the other end extends out of the box. The box is fixed to the upper cover plate of the support.

[0010] Furthermore, a turntable is fixed to the end of the rotating shaft that extends out of the housing. This allows for manual rotation of the shaft to lower the cleaning ball to the bottom.

[0011] Furthermore, a torsion spring is provided on the rotating shaft, with one end fixed to the side wall of the housing and the other end fixed to the turntable. When the lowest cleaning ball falls, the first cleaning ball above it is restricted in the hopper by the first limiting plate. After the hand leaves the turntable, the torsion spring drives the rotating shaft to rotate in the opposite direction, so that the first limiting plate moves away from the hopper and the second limiting plate moves closer to the hopper. At this time, the second to last cleaning ball from top to bottom falls to the position of the original lowest cleaning ball.

[0012] Furthermore, both the inner walls of the box and the hopper are provided with sliding grooves, and both ends of the first and second limiting plates are provided with sliding parts that cooperate with the sliding grooves. This ensures that the first and second limiting plates slide smoothly within the hopper and the box.

[0013] Furthermore, the telescopic mechanism is fixed to the end of the feed pipe via a flange.

[0014] Furthermore, a conical top block is fixed to the output end of the telescopic mechanism for pushing the cleaning ball during the telescopic mechanism's movement. This increases the contact area between the top block and the cleaning ball, improving transport efficiency.

[0015] Furthermore, the telescopic mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0016] Through the above technical solution, the beneficial effects of this utility model are as follows: In the initial state, the bottommost cleaning ball in the hopper is blocked by the second limiting plate, and the first limiting plate has not yet extended into the hopper. When the rotating shaft rotates, it drives the gear to rotate. The rack meshing with the gear drives the first limiting plate and the second limiting plate to move closer and then further apart. The bottommost cleaning ball falls into the feeding pipe. After the valve is opened, it is pushed into the paste pipe by the telescopic mechanism to wait for subsequent cleaning work. At this time, the second to last cleaning ball from top to bottom is blocked by the first limiting plate to prevent it from falling. The turntable is equipped with a torsion spring. After the operator leaves the turntable, the rotating shaft rotates in the opposite direction, driving the first limiting plate to move away from the hopper and the second limiting plate to move closer to the hopper, so that the second to last cleaning ball falls to the original bottommost cleaning ball position. This realizes that multiple cleaning balls in the hopper are transported one by one to the feeding pipe, improving work efficiency. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1-4As shown, this embodiment provides a feeding device for cleaning balls in a paste pipeline, including a feeding pipe 2 connected to a paste pipeline 1. A valve 3 is provided on the feeding pipe 2. The valve 3 controls the connection between the feeding pipe 2 and the paste pipeline 1, preventing the cleaning balls 5 fed into the paste pipeline 1 from re-entering the feeding pipe 2. A square hopper 4 is connected to the upper side of the feeding pipe 2. The valve 3 is located between the paste pipeline 1 and the hopper 4. A row of multiple cleaning balls 5 is arranged in the hopper 4 from top to bottom. A ball feeding mechanism is also provided on one side of the hopper 4.

[0024] It also includes a support 10, with the feeding pipe 2 fixedly installed on the side wall of the support 10. The upper end of the hopper 4 extends out of the upper cover plate of the support 10. A box 11 is provided on one side of the hopper 4, and the box 11 is fixed to the upper cover plate of the support 10. The ball feeding mechanism is disposed in the box 11.

[0025] refer to Figure 3 and Figure 4 The ball feeding mechanism includes a first limiting plate 6, a second limiting plate 7, a rack 8, and a gear 9. The first limiting plate 6 is located above the second limiting plate 7. A rack 8 is provided on the opposite side of the first limiting plate 6 and the second limiting plate 7. The gear 9 is located between the two racks 8 that are opposite to the first limiting plate 6 and the second limiting plate 7 and meshes with the two racks 8 to realize that the first limiting plate 6 and the second limiting plate 7 move closer or further apart when the gear 9 rotates.

[0026] Both the first limiting plate 6 and the second limiting plate 7 are slidably disposed on the inner side wall of the box 11. The ball feeding mechanism also includes a rotating shaft 12, which is fixedly mounted on the gear 9. One end of the rotating shaft 12 is rotatably connected to the inner side wall of the box 11, and the other end extends out of the box 11.

[0027] Specifically, the inner walls of the box 11 and the hopper 4 are provided with sliding grooves 14, and both ends of the first limiting plate 6 and the second limiting plate 7 are provided with sliding parts that cooperate with the sliding grooves 14.

[0028] In this embodiment, a turntable 13 is fixed to the end of the rotating shaft 12 that extends out of the housing 11. A torsion spring is provided on the rotating shaft 12, with one end fixed to the side wall of the housing 11 and the other end fixed to the turntable 13. In other embodiments, a motor can also be used to connect to the rotating shaft 12.

[0029] The first limiting plate 6 and the second limiting plate 7 are respectively disposed on the upper and lower sides of the bottommost cleaning ball 5. The end of the first limiting plate 6 extends into the inner wall of the hopper 4 and is flush with the inner wall of the hopper 4. The end of the second limiting plate 7 extends into the interior of the hopper 4 and contacts the bottommost cleaning ball 5.

[0030] The end of the feeding pipe 2 is equipped with a telescopic mechanism 16, which is used to transport the cleaning balls 5 falling into the feeding pipe 2 to the paste pipe 1. The telescopic mechanism 16 is fixed to the end of the feeding pipe 2 by a flange. A conical top block 15 is fixed to the output end of the telescopic mechanism 16. The telescopic mechanism 16 is a cylinder or a hydraulic cylinder. The telescopic mechanism 16 is fixedly connected to the bracket 17 fixed to the bottom plate of the support 10.

[0031] In the initial state: the end of the first limiting plate 6 extends into the inner wall of the side close to the hopper 4 and is flush with the inner wall of the hopper 4; the end of the second limiting plate 7 extends into the inner wall of the side away from the hopper 4 and is flush with the inner wall of the hopper 4; at this time, the bottommost cleaning ball 5 falls on the second limiting plate 7.

[0032] When the cleaning ball 5 is needed, the turntable 13 is manually rotated, which drives the rotating shaft 12 to rotate. The gear 9, which is fixedly connected to the rotating shaft 12, drives the first limiting plate 6 to move towards the material hopper 4 and the second limiting plate 7 to move away from the material hopper 4. At this time, the cleaning ball 5 at the bottom falls into the feeding pipe 2. After the valve 3 is opened, it is pushed into the paste pipe 1 by the telescopic mechanism 16 to wait for subsequent cleaning work.

[0033] After the cleaning ball 5 falls into the paste pipe 1, the valve 3 is closed. After the person leaves the turntable 13, the rotating shaft 12 is reversed by the reverse force of the torsion spring, which drives the first limiting plate 6 to move away from the hopper 4 and the second limiting plate 7 to move closer to the hopper 4, so that the second to last cleaning ball 5 falls to the original bottom cleaning ball 5, waiting for subsequent use.

[0034] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
