Description

TECHNICAL FIELD

[0001] The utility model relates to mine drainage technical field, and specifically, relate to a mine drainage anti -blockage filter device. BACKGROUND

[0002] In underground engineering operations such as mine exploitation and tunnel construction, effective discharge of underground gushing water is a key link to ensure construction safety and maintain normal production.

[0043] It should be noted that the controller control circuit can be realized through simple programming by those skilled in the art, which belongs to the common knowledge in the art, and only the use is described without modification, so the control mode and circuit connection are not described in detail.

[0044] The use process of the mine drainage anti-blocking filter device provided by the utility model is as follows:

[0045] In use, the top water diversion support cover plate 1 supports and guides the water of the mine tunnel roof, effectively preventing the roof rock from collapsing, and at the same time, the mine tunnel seepage water is guided to the drainage port 9 through the structure, and then injected into the collecting hopper 17 and introduced into the large-diameter drainage pipeline 3; after the water flow is transported through the pipeline to the filter box 4, the filter screen 19 arranged inside is used to intercept and filter the silt and solid impurities contained in the water body, and the purified water continues to be discharged into the collecting pipeline 5 through the large-diameter drainage pipeline 3 and transported to the designated discharge point, so as to avoid the deposition of silt in the collecting pipeline 5, thereby preventing the system from being blocked and ensuring the smooth drainage of the mine tunnel. When the impurities on the surface of the filter screen 19 affect its flow capacity, the upper flow sensor 15 and the lower flow sensor 12 are used to monitor the flow of the upper and lower reaches of the large-diameter drainage pipeline 3, respectively. If the difference exceeds the set threshold, the controller 8 determines that the filter screen 19 is blocked, and then closes the electric valve body 16 of the pipeline to suspend drainage. At this time, the remaining large-diameter drainage pipelines 3 still maintain normal operation. After the electric valve body 16 is closed, the controller 8 starts the electric telescopic rod 18, the driving end of which pushes the sealing plate 11 to displace outward, thereby achieving the sealing and unsealing of the outer port of the filter box 4. At the same time, the connecting rod 14 drives the cleaning block 20 and the scraping assembly 21 mounted thereon to move forward. The scraping assembly 21 is integrated with a rubber scraper and a brush double cleaning structure, which scrapes and brushes the silt attached to the surface of the filter screen 19 during movement, pushes the removed impurities to the outer port of the filter box 4, and finally makes them fall into the collection groove 6 for centralized storage. After the cleaning operation is completed, the electric telescopic rod 18 drives the scraping assembly 21 to reset to the inner position of the filter box 4, the sealing plate 11 reseals the port, and then the electric valve body 16 is opened, and the system resumes drainage operation. Each parallel large-diameter drainage pipeline 3 can realize autonomous start and stop according to sensor feedback, and complete automatic slag cleaning operation relying on the cleaning and sealing assembly 7. Through real-time monitoring and feedback control, the clogging state of the filter screen 19 is recognized and cleaned automatically, which maintains the good water permeability of the filter screen 19 and ensures the overall stability of the drainage system. The whole process does not require manual intervention, and relies on the electric telescopic rod 18 as the execution power, which is reliable in action and stable in operation, significantly improving the long-term working reliability and maintenance automation level of the system in the complex environment of the mine tunnel.
