Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a spiral mixer for mining polymer reinforcement materials. Background Technology

[0002] In underground coal mining, roof management is crucial for safe production. Roof collapses and spalling caused by fractured coal and rock masses have always been technical challenges. With increasing mining depth and water inflow, roof management becomes even more difficult, urgently requiring effective chemical reinforcement technologies and materials. Currently used polymeric chemical materials suffer from heat accumulation during application, with internal temperatures reaching over 100°C, posing a safety hazard of igniting methane gas in high-gas environments.

[0003] The spiral mixer conveys and mixes the multi-component raw materials of polymer reinforcement materials, providing uniformly mixed materials for operations such as roadway support and roof reinforcement. It is one of the key pieces of equipment to ensure safe mining.

[0004] Currently, conventional mixing methods may suffer from problems such as uneven mixing and low efficiency, failing to meet the needs of large-scale rapid reinforcement in coal mines. Furthermore, they are difficult to transport according to space constraints. During the transportation process, they lack the function of filtering polymer reinforcement materials, which can easily lead to blockage of the discharge mechanism, making them inconvenient to use. At the same time, the discharge mechanism has a single discharge port, which can easily cause resistance. Therefore, we propose a spiral mixer for mining polymer reinforcement materials to solve the above problems. Utility Model Content

The right side of the cylinder is open. A filter screen is placed inside the cylinder. Feeding mechanisms are installed on the left side wall of the cylinder near the top and bottom.

[0007] Furthermore, the first connecting mechanism includes a first flange, a second flange, a rubber sealing ring, and a fastening bolt assembly. The first flange is fixedly installed on the right side of the round pipe, and the second flange is fixedly installed on the left side of the metal flexible hose. A rubber sealing ring is provided between the first flange and the second flange, and the first flange and the second flange are locked and fixed together by the fastening bolt assembly.

[0008] Furthermore, the discharge mechanism includes a discharge head, a flow channel, and a discharge channel. The discharge head is threadedly installed on the right side of the metal hose. A flow channel is provided between the left and right sides of the discharge head. A discharge channel is uniformly provided on the outer surface of the discharge head corresponding to the flow channel.

The first flange 301 is fixedly installed on the right side of the round pipe 1, and the second flange 302 is fixedly installed on the left side of the metal flexible hose 4. A rubber sealing ring 303 is provided between the first flange 301 and the second flange 302, and the first flange 301 and the second flange 302 are locked and fixed together by the fastening bolt assembly 304.

[0019] In this embodiment, the fastening bolt assembly 304 connects and fixes the first flange 301 and the second flange 302, and the rubber sealing ring 303 improves the sealing effect between the first flange 301 and the second flange 302, thereby achieving the effect of connecting and fixing the round pipe 1 and the metal hose 4.

[0020] like Figure 3As shown, in some embodiments, the discharge mechanism 5 includes a discharge head 501, a flow channel 502, and a discharge channel 503. The discharge head 501 is threaded onto the right side of the metal hose 4. The flow channel 502 is provided between the left and right sides of the discharge head 501. The discharge channel 503 is uniformly provided on the outer surface of the discharge head 501 corresponding to the flow channel 502.

[0021] In this embodiment, the discharge head 501 is threaded onto the metal hose 4. The polymer material inside the metal hose 4 flows into the flow channel 502 and flows out through the opening on the right side of the flow channel 502 and the discharge channels 503 around it. Multiple discharge ports effectively prevent the discharge from being blocked.

[0022] like Figure 1 As shown, in some embodiments, the second connecting mechanism 6 has the same structure as the first connecting mechanism 3.

[0023] In this embodiment, the second connecting mechanism 6 connects and fixes the round tube 1 and the round cylinder 7, so as to achieve the effect of installing the feeding mechanism 9 and make the filter screen 8 detachable for cleaning.

[0024] like Figure 2 As shown, in some embodiments, the left side of the filter screen 8 is an open structure, the outer surface of the filter screen 8 is in contact with the inner wall of the cylinder 7, and the left and right sides of the filter screen 8 are in contact with the left inner wall of the cylinder 7 and the inner wall of the second connecting mechanism 6, respectively.

[0025] In this embodiment, the filter screen 8 is installed stably and can filter impurities in the polymer material entering through the feeding mechanism 9.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the feeding mechanism 9 includes a feeding pipe 901 and a flow control valve 902. The feeding pipe 901 is fixedly installed on the left side wall of the cylinder 7, and the flow control valve 902 is fixedly installed on the feeding pipe 901.

[0027] In this embodiment, the feed pipe 901 is connected to the polymer material conveying pipe, so that the polymer material flows into the cylinder 7 through the feed pipe 901.

The mixed polymer material flows... The material enters through the metal hose 4 and then flows into the flow channel 502 in the discharge mechanism 5. It is then reinforced by flowing out through the opening on the right side of the flow channel 502 and the discharge channels 503 around it. Multiple discharge ports effectively prevent the discharge from being blocked, making the polymer material mix evenly and efficiently. The multi-component feeding ratio is adjustable, and it can filter impurities in the incoming polymer material to avoid clogging. The discharge direction can be adjusted, allowing for discharge in multiple directions to avoid contact and blockage with the wall in one direction. This provides great flexibility for the use of the mixer, allowing it to be easily adapted to different spatial layouts and meet diverse operational needs.

[0031] In summary, this spiral mixer for mining polymer reinforcement materials uses static mixing blades 2 inside the circular tube 1 to ensure uniform and efficient mixing of polymer materials. It also allows for adjustable multi-component feeding ratios, filters impurities in the incoming polymer materials to prevent clogging of the discharge mechanism 5, and the metal hose 4 can adjust the orientation of the discharge mechanism 5. This provides great flexibility for the mixer's application scenarios, allowing it to easily adapt to different spatial layouts and meet diverse operational needs.
