[0002] The pneumatic injection pump is a pneumatic high-pressure emulsion pump station in coal mines. It is mainly suitable for the temporary rapid column support of underground working faces in coal mines. When the hydraulic oil inside the injection pump is used for a long time, the hydraulic oil often contains granular impurities, which will cause wear on the relative moving surface of the hydraulic components, slide valve stagnation, and throttling orifice blockage, greatly reducing the working reliability of the system.

[0003] The Chinese patent with the patent number CN212523257U discloses a "liquid filter structure of a pneumatic injection pump for mining", which includes a shell, a sealing top cover is threadedly sleeved on the upper part of the outer shell, a filter copper mesh is clamped inside the shell, an oil inlet pipe is fixedly installed on the top of the sealing top cover, and a clamping plate is clamped inside the oil inlet pipe. After the sealing top cover is screwed on the outer shell, a tension is applied to the limit rod by a tension spring, so that the top end of the limit rod is clamped between the limit plates on the outer side of the sealing top cover, and the relative position of the shell and the sealing top cover is limited by the limit rod and the limit plate, thereby ensuring the stability of the connection between the sealing top cover and the shell, thereby ensuring the sealing of the shell and the sealing top cover;

[0004] Although the above-mentioned mining pneumatic injection pump filter structure has certain advantages in sealing ability, the transmission turbine cannot ensure the rapid rotation of the wire brush by injection, and the wire brush brushes the foreign particles, which may easily adhere to or get stuck in the filter holes of the filter copper mesh.

[0023] See also Figure 5The utility model provides a mining pneumatic injection pump filtering machine, the rotating structure 14 comprises a filter copper frame 141, a filter hole 142 and a second rotating shaft 143. The outer wall of the filter copper frame 141 is provided with a filter hole 142, and the right end surface of the filter copper frame 141 is provided with a second rotating shaft 143, and the right end of the second rotating shaft 143 is rotatably connected to the inner wall of the second shell 12 through a bearing. The left side of the filter copper frame 141 penetrates the second shell 12 and the first shell 11, and the right side of the pump head 3 penetrates the first shell 11 and fits with the left side of the filter copper frame 141, which is beneficial for the pump head 3 to extract the oil filtered by the filter copper frame 141 to the left side, and the second bevel gear 134 is sleeved on the left side of the filter copper frame 141, so that the second bevel gear 134 drives the filter copper frame 141 to rotate through the first bevel gear 133, and the second rotating shaft 143 and the filter copper frame 141 are at the same horizontal center line, which is beneficial for the filter copper ore 141 to rotate without affecting the pump head to pump liquid.

[0024] Here’s how it works:

[0025] First, place the utility model at the desired location and make circuit connections;

[0026] Second, the motor 2 is controlled to operate, and the output end of the motor 2 drives the pump head 3 to pump liquid through the rotating shaft, and at the same time, the valve of the oil inlet pipe 15 is opened, so that the pipeline connected to the oil inlet pipe 15 will add oil to the interior of the second housing 12;

[0027] Third, the pulley group 131 is driven by the motor 2, so that the pulley group 131 drives the first rotating shaft 132 to rotate, and the first rotating shaft 132 drives the first bevel gear 133 to rotate. Since the first bevel gear 133 is meshed with the second bevel gear 134, the first bevel gear 133 drives the second bevel gear 134 to rotate. Because the second bevel gear 134 is mounted on the left side of the filter copper frame 141, the second bevel gear 134 drives the filter copper frame 141 to rotate. By utilizing the characteristic that the second rotating shaft 143 and the filter copper frame 141 have the same horizontal center line, the filter copper frame 141 can rotate while being in contact with the pump head 3, thereby avoiding affecting the pumping of the pump head 3. When the filtration is completed, the oil with impurity particles can be discharged to the outside by opening the valve of the drain pipe 16.
