The metal particles have economic value and can be recycled, effectively avoiding waste of metal resources and greatly improving the filtration effect.

Description

Technical Field

[0001] This utility model provides a coal mine water filtration and treatment device, belonging to the field of coal mine water filtration and treatment technology. Background Technology

[0002] Coal mines are areas where humans extract coal resources from coal-rich areas, generally divided into underground coal mines and open-pit coal mines. Coal mine water filtration and treatment devices are water treatment equipment specifically designed for underground coal mining faces. Their main function is to filter impurities from the water source in the underground fully mechanized mining face, ensuring water quality cleanliness, preventing impurities from damaging equipment and the production process, and simultaneously ensuring the safety of coal mine production and workers.

[0003] Existing coal mine water filtration devices can basically meet normal usage needs, but they still have certain shortcomings: Since underground coal mines do contain some magnetic metals, such as magnetite and hematite, which are common magnetic minerals in the underground environment during mining, coal mine water usually contains a certain amount of iron filings and other metal particulate impurities. These metal particulate impurities have economic value and can be recycled. However, during coal mine water filtration, these metal particulate impurities are often mixed with a large amount of sand and gravel impurities and are not separated before being uniformly cleaned, resulting in a waste of metal resources and a need to improve the filtration effect. Based on this, this utility model provides a coal mine water filtration device. Utility Model Content

[0004] The technical problem solved by this utility model is that metal particle impurities and a large amount of sand and gravel impurities in coal mine water are often mixed together and cannot be separated before being cleaned in a unified manner, resulting in a waste of metal resources and the filtration effect needs to be improved.

[0005] To solve the technical problem, the present invention provides the following technical solution: a coal mine water filtration and treatment device, comprising a treatment box, wherein filter tray one, filter tray two, and filter tray three are slidably inserted between the inner side walls of the treatment box from top to bottom; a magnetic suction assembly is provided in the upper part of the treatment box; each of filter tray one, filter tray two, and filter tray three includes a drawer box slidably connected to the inner side wall of the treatment box; the magnetic suction assembly includes a magnetic rod placed above filter tray one; a water inlet is provided on one side of the top of the treatment box, and an inclined water pipe is provided at the bottom outlet of the water inlet for water to flow upward toward the magnetic rod side inside the treatment box.

[0006] Furthermore, the top of the filter drawer is provided with an opening directly below the magnetic rod and filter ports on both sides of the opening. An annular scraper is fixedly connected between the inner walls of the opening and the inner wall of the drawer. The inner wall of the annular scraper is in contact with the outer wall of the magnetic rod. A ceramic filter membrane is fixedly connected between the inner walls of the filter ports.

[0007] Furthermore, the top of the filter tray is provided with a filter port, and a ceramic filter membrane is fixedly connected between the inner walls of the filter port.

[0008] Furthermore, the top of the filter tray 3 is provided with a filter port 3, and an activated carbon filter screen is fixedly connected between the inner side walls of the filter port 3.

[0009] Furthermore, each of the filter drawers includes a baffle fixedly mounted on one side wall of the drawer box. The baffle has a handle on its side wall and is fixedly connected to the outer side wall of the processing box by bolts. Both sides of the drawer box are provided with limiting rails that match the inner side wall of the processing box.

[0010] Furthermore, the magnetic suction assembly also includes an electric push rod fixedly installed on the top of the processing box.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] According to the appendix Figure 1 , 3 As shown: This utility model provides a coal mine water filtration treatment device, including a treatment box 1. Filter tray 1 2, filter tray 2 3, and filter tray 3 4 are slidably inserted between the inner side walls of the treatment box 1 from top to bottom. Each of the filter trays 1 2, 2 3, and 3 4 includes a drawer box 6 slidably connected to the inner side wall of the treatment box 1. Each of the filter trays 1 2, 2 3, and 3 4 also includes a baffle 15 fixedly installed on one side wall of the drawer box 6. A handle is provided on the side wall of the baffle 15. The baffle 15 is fixedly connected to the outer side wall of the treatment box 1 by bolts. Each side wall of the drawer box 6 is provided with a limiting rail 16 that matches the inner side wall of the treatment box 1, which serves to limit the drawer box 6. Specifically, by removing and installing bolts, the filter trays 1 2, 2 3, and 3 4 inside the treatment box 1 can be easily pulled in and out, making it convenient for workers to clean the inside of the drawer box 6.

[0023] As per the instruction manual Figure 2 , 3As shown in Figure 4: The top of the filter tray 2 (drawer box 6) has an opening 10 located directly below the magnetic rod 7, and filter ports 1 located on both sides of the opening 10. An annular scraper 11 located inside the drawer box 6 is fixedly connected between the inner walls of the opening 10. The inner wall of the annular scraper 11 contacts the outer wall of the magnetic rod 7. A ceramic filter membrane 12 is fixedly connected between the inner walls of the filter ports 1. A magnetic suction assembly 5 is provided in the upper part of the processing box 1. The magnetic suction assembly 5 includes the magnetic rod 7 located above the filter tray 2, and also includes an electric push rod 17 fixedly installed on the top of the processing box 1. The telescopic rod end of rod 17 is inserted into the processing box 1 and fixedly connected to a waterproof motor 18. The output end of the waterproof motor 18 is fixedly connected to the top of the magnetic rod 7. The bottom of the magnetic rod 7 is provided with a guide cone 19. Specifically, by starting the waterproof motor 18 to run at low speed, the magnetic rod 7 can be driven to rotate slowly at low speed. By starting the electric push rod 17, the waterproof motor 18 and the magnetic rod 7 can be driven to rise and fall. The magnetic rod 7 moves down into the annular scraper 11. The annular scraper 11 can scrape off the iron filings and other metal particles that are magnetically attracted to the outer wall of the magnetic rod 7 and collect them in the drawer box 6 of the filter tray 2.

[0024] As per the instruction manual Figure 1 , 2 As shown in Figure 3: Filter tray 2 (3 drawer box 6) has a filter port 2 at its top. A ceramic filter membrane 13 is fixedly connected between the inner walls of filter port 2. The ceramic filter membrane removes impurities such as microorganisms, bacteria, and metal ions from the water through osmosis. Filter tray 3 (4 drawer box 6) has a filter port 3 at its top. An activated carbon filter 14 is fixedly connected between the inner walls of filter port 3. The activated carbon filter mainly adsorbs odors, harmful chemicals, and some heavy metal ions from the water. A water inlet 8 is located on one side of the top of treatment box 1. The bottom outlet of water inlet 8 has an inclined water pipe 9 placed inside treatment box 1 and flowing water upwards towards the magnetic rod 7. A water outlet 20 is located below filter tray 3 (4) on the lower part of the side wall of treatment box 1. The 20 is equipped with a switch valve. Specifically, the coal mine water flows through the inlet hopper 8 and the inclined water pipe 9 to the upper part of the magnetic rod 7, and then flows down along the magnetic rod 7. After being guided by the guide cone, it continues to flow down through the outlet 10. A small amount of coal mine water splashed into the filter tray 1 2 can be filtered by the ceramic filter membrane 1 2 to prevent a large amount of water from accumulating in the filter tray 1 2. A large amount of coal mine water passes through the outlet 10 and is filtered sequentially through the filter tray 2 3 and the filter tray 3 4. The ceramic filter membrane 2 1 3 filters the water before the activated carbon filter screen, which can ensure that the water first passes through the ceramic filter membrane to remove bacteria, viruses and other tiny impurities, and then passes through the activated carbon filter screen 1 4 to remove odors and harmful substances. The filtered coal mine water is discharged from the outlet pipe 20.

[0025] The control method of this utility model is through a controller. The controller adopts existing known mature technology, which is not shown in the figure and will not be described in detail here. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0026] The principle of this utility model

[0027] In use, coal mine water flows through the inlet hopper 8 and inclined water pipe 9 to the upper side of the magnetic rod 7, and then flows down along the magnetic rod 7 and guide cone 19, falling into the filter tray 2 3 through the outlet 10. The water first passes through the ceramic filter membrane to remove bacteria, viruses and other tiny impurities, and then passes through the activated carbon filter 14 to remove odors and harmful substances. The filtered coal mine water is discharged from the outlet pipe 20. Through the magnetic suction component 5, the waterproof motor 18 is started to run at low speed, which can drive the magnetic rod 7 to rotate slowly at low speed. This causes the metal particles such as iron filings in the coal mine water flowing onto the magnetic rod 7 to be magnetically attracted to the outer wall of the magnetic rod 7. When cleaning is required, the electric push rod 17 is started to drive the magnetic rod 7 down into the annular scraper 11. The annular scraper 11 can scrape the metal particles such as iron filings on the outer wall of the magnetic rod 7 into the drawer box 6 of the filter tray 2 for collection. This effectively separates the metal particles from a large amount of sand and gravel impurities for separate cleaning. The metal particles have economic value and can be recycled, effectively avoiding the waste of metal resources, thus greatly improving the filtration effect.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
