Description

Technical Field

[0001] This utility model belongs to the field of pipeline cleaning technology, specifically relating to a cleaning device for underground filling pipelines in mines. Background Technology

[0002] As the mine continues to be mined deeper, the filling pipelines become longer. To ensure unobstructed flow, the pipelines need to be rinsed with clean water for 8-12 minutes after filling to ensure the slurry inside is thoroughly cleaned. This process consumes a large amount of water. However, due to the lower flushing water pressure in the mine's horizontal tunnels, slurry residue remains on the inner walls of the filling pipelines, affecting the progress of subsequent filling operations, causing blockages, and directly impacting normal production. Utility Model Content

[0003] The purpose of this invention is to provide a cleaning device for underground filling pipelines in mines, in order to solve the problems of difficulty in cleaning residual slurry on the inner wall of existing mine horizontal tunnel filling pipelines and high water consumption.

[0004] The technical solution of this utility model is: a cleaning device for underground filling pipes in a mine, including a lower shell, which is a semi-circular cavity. The lower shell is provided with a first opening, a second opening and a third opening. A water pipe is provided next to the second opening. A grid plate is provided on the upper surface of the lower shell. An upper shell is provided on the upper surface of the grid plate. The upper shell is a rectangular cavity. A fourth opening is provided on the top of the upper shell.

[0005] As a further improvement of this utility model, a one-way guide valve is provided on the water pipe.

[0006] As a further improvement of this utility model, the first opening and the second opening are arranged horizontally and symmetrically on both sides of the lower shell, and stiffeners are provided between the first opening and the second opening and the lower shell.

[0007] As a further improvement of this utility model, the lower shell, the grating plate and the upper shell are fixedly connected by high-strength hexagonal head bolts.

[0008] As a further improvement of this utility model, the water pipe port is provided with threads.

[0009] The beneficial effects of this utility model are as follows:

[0010] During the filling operation, the external gate valve of the third interface is closed, and the lower shell cavity serves as a transition section connecting the filling pipes at both ends. After the filling work is completed, the external high-pressure air switch of the fourth opening is opened, and the mortar impurities remaining in the external filling pipe are blown out of the filling pipe by the high-pressure air. After the water pipe is connected to water, the high-pressure air can further clean the entire cavity and the external filling pipe. Finally, the external gate valve of the third interface is opened to drain the sewage remaining in the cavity.

[0011] The device and method used in this utility model are easy to install and operate, highly practical, reduce labor, and solve the technical problems of difficult cleaning of residual slurry on the inner wall of existing mine horizontal tunnel filling pipes and large water consumption, thereby improving the actual application effect of this utility model.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figures 1-4 As shown, the device used in this embodiment includes a lower housing 1, which is a semi-circular cavity. The lower housing 1 has a first opening 2, a second opening 3 and a third opening 4. The first opening 2 and the second opening 3 are respectively connected to filling pipes. The third opening 4 is connected to a gate valve. A water pipe 5 is provided on the side of the second opening 3. A one-way guide valve 6 is arranged on the water pipe 5. A grid plate 7 is provided on the end face of the lower housing 1 to separate the upper and lower housings. An upper housing 8 is provided on the end face of the grid plate 7. The upper housing 8 is a rectangular cavity. A fourth opening 9 is provided on the top of the upper housing 8.

[0020] It should be noted that the first opening 2 and the second opening 3 are arranged horizontally symmetrically. The first opening 2 and the second opening 3 are reinforced and fixed to the lower shell 1 by stiffening plates 10. The first opening 2, the second opening 3, the third opening 4 and the fourth opening 9 are all connected to the external components by flanges. The lower shell 1, the grating plate 7 and the upper shell 8 are fixedly connected by M10*40mm high-strength hexagonal head bolts 11. The water pipe 5 has threads at the port. The flange end face of the third opening 4 is 10cm-15cm away from the bottom horizontal section of the lower shell 1. The flange end faces of the first opening 2 and the second opening 3 are 15cm-20cm away from the two side end faces of the lower shell 1, respectively. The flange end face of the fourth opening 9 is 20cm-30cm away from the top end face of the upper shell 8.

[0021] The device used in this embodiment is operated as follows:

[0022] During the filling operation, the external gate valve of the third interface 4 of the device is closed. The lower shell 1 of the device serves as a transition section connecting the filling pipes at both ends. After the filling work is completed, the external high-pressure air switch of the fourth opening 9 is opened. The mortar impurities remaining in the external filling pipe are blown out of the filling pipe by the high-pressure air. After the water pipe 5 is connected to water, it can further clean the entire cavity of the lower shell 1 and the external filling pipe in conjunction with the high-pressure air. Finally, the external gate valve of the third opening 4 is opened to drain the sewage remaining in the cavity of the lower shell 1. In addition, the water pipe 5 can be switched on and off according to the actual situation on site to ensure that the filling pipe and the cavity of the lower shell 1 are cleaned and to reduce water waste.
