Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a wastewater treatment device for underground coal mines. Background Technology

[0002] During coal mining, the aquifer zone is damaged, and the fissure water flows downwards, forming stagnant water. As the mine water flows, it carries away fine particles from the coal deposit, so the wastewater often contains a large amount of suspended minerals and coal particles. In order to ensure safe mining underground, the mine water is discharged. Direct discharge not only wastes resources but also pollutes the environment, so it is necessary to treat the mine water.

[0003] In existing technologies, underground coal mine wastewater treatment devices require flocculation of wastewater. However, conventionally, flocculants are simply poured into the wastewater, resulting in uneven distribution of the flocculant, poor flocculation effect, and a large number of impurities generated after flocculation. These impurities can quickly clog the filter components, requiring frequent shutdowns to clean or replace them. This is cumbersome and makes it difficult to collect and discharge the filtered impurities. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 This utility model discloses a wastewater treatment device for underground coal mines, including a housing 1. A partition 2 is fixedly installed on the inner wall of the housing 1 near the left side, and the partition 2 divides the housing 1 into a flocculation chamber 3 and a filtration chamber 4 from left to right. A water inlet pipe 5 is provided on the left side wall of the housing 1 near the upper side. A slag discharge mechanism 6 is provided on the lower edge of the left side wall of the housing 1. A cylinder 7 is fixedly installed on the right side wall of the housing 1 near the upper side between the partition 2 and the right side wall of the housing 1. The left side of the cylinder 7 is open. An electric... The motor 8 has a transmission pipe 9 fixedly installed on the left side of its output shaft. A stirring mechanism 10 is provided on the transmission pipe 9 at a position corresponding to the flocculation chamber 3. A filtering mechanism 11 is provided on the transmission pipe 9 at a position corresponding to the filtering chamber 4. A liquid distribution mechanism 12 is provided on the transmission pipe 9 near the right side. The liquid distribution mechanism 12 is connected to the liquid storage tank 14 through an extraction component 13. The liquid storage tank 14 is installed on the upper surface of the tank body 1. A collection mechanism 15 is provided on the lower side wall of the cylinder 7. A drain valve 16 is provided on the lower edge of the right side wall of the tank body 1.

[0021] Specifically, the slag discharge mechanism 6 includes a guide plate 601 and a slag discharge valve 602. The guide plate 601 is installed at an angle between the inner walls of the flocculation chamber 3, and the slag discharge valve 602 is installed on the left side wall of the box 1 corresponding to the guide plate 601.

[0022] In this embodiment, the guide plate 601 directs the impurities precipitated in the flocculation chamber 3 to the slag discharge valve 602, and opening the slag discharge valve 602 allows the impurities to be discharged.

[0023] Specifically, the transmission tube 9 has a hollow structure, and the left end of the transmission tube 9 is connected to the left inner wall of the housing 1 through the bearing assembly 17.

[0024] In this embodiment, the bearing assembly 17 fixes the transmission tube 9, making the installation of the transmission tube 9 more stable and secure, and facilitating the rotation of the transmission tube 9.

[0025] Specifically, the stirring mechanism 10 includes a stirring tube 101 and a one-way nozzle 102. The stirring tube 101 is evenly installed on the corresponding transmission tube 9 of the flocculation chamber 3, and the one-way nozzle 102 is evenly arranged on the stirring tube 101.

[0026] In this embodiment, the flocculant in the transmission pipe 9 flows into the stirring pipe 101, and then is sprayed into the flocculation chamber 3 through the one-way nozzle 102 on the stirring pipe 101. At the same time, the stirring pipe 101 rotates with the transmission pipe 9, so that the stirring pipe 101 drives the one-way nozzle 102 to stir the sewage and flocculant in the flocculation chamber 3, so that the flocculant is evenly distributed and can fully mix and react with the sewage in the flocculation chamber 3.

[0027] Specifically, the filtration mechanism 11 includes a metal filter plate 111 and a feeding spiral blade 112. The metal filter plate 111 is fixedly embedded on the lower side wall of the cylinder 7. The feeding spiral blade 112 is fixedly installed on the transmission pipe 9 at a position corresponding to the cylinder 7, and the feeding spiral blade 112 is movably attached to the inner wall of the cylinder 7 and the feeding spiral blade 112.

[0028] In this embodiment, the sewage flowing into the cylinder 7 is filtered by the metal filter plate 111, which filters out impurities from the sewage. The filtered water flows to the lower side of the filter chamber 4, and the filtered impurities remain in the metal filter plate 111 and the cylinder 7. This causes the transmission pipe 9 to drive the feeding screw blade 112 to rotate, and the feeding screw blade 112 drives the impurities to move towards the right side of the cylinder 7, so that the impurities fall into the collection mechanism 15. The metal filter plate 111 has an arc-shaped structure, and the arc of the metal filter plate 111 is the same as the arc of the cylinder 7. At the same time, the inner wall of the metal filter plate 111 is flush with the inner wall of the cylinder 7.

[0029] Specifically, the liquid distribution mechanism 12 includes a sealing plate 121, a liquid distribution chamber 122, a liquid inlet 123, and a mechanical seal 124. The sealing plate 121 is fixedly installed on the inner wall of the cylinder 7 near the right side. The liquid distribution chamber 122 is provided between the sealing plate 121 and the inner wall of the right side of the cylinder 7, and the transmission pipe 9 corresponding to the liquid distribution chamber 122 is provided with a liquid inlet 123. Mechanical seals 124 are installed on the sealing plate 121 and the right side wall of the cylinder 7 at positions corresponding to the transmission pipe 9.

[0030] In this embodiment, the liquid distribution chamber 122 is used to receive the flocculant drawn in by the extraction component 13. The flocculant in the liquid distribution chamber 122 flows into the transmission pipe 9 through the liquid inlet hole 123. The mechanical seal 124 makes the sealing effect between the sealing plate 121 and the right side wall of the cylinder 7 and the transmission pipe 9 better.

[0031] Specifically, the collection mechanism 15 includes a collection box 151 and a sealing cover 152. The collection box 151 is installed on the lower surface of the cylinder 7 corresponding to the right end of the feeding screw blade 112, and the sealing cover 152 is threaded onto the lower surface of the collection box 151.

[0032] In this embodiment, the collection box 151 can collect impurities inside the cylinder 7, and opening the sealing cover 152 facilitates the discharge of impurities from the collection box 151.

[0033] During operation, coal mine wastewater flows into the flocculation chamber 3 through the inlet pipe 5. The flocculant in the storage tank 14 is drawn into the distribution chamber 122 of the distribution mechanism 12 by the extraction component 13. The flocculant in the distribution chamber 122 flows into the transmission pipe 9 through the inlet hole 123. The flocculant in the transmission pipe 9 flows into the stirring pipe 101 of the stirring mechanism 10, and is then sprayed into the flocculation chamber 3 through the one-way nozzle 102 on the stirring pipe 101. Simultaneously, the output shaft of the motor 8 drives the transmission pipe 9 to rotate, causing the transmission pipe 9 to drive the stirring pipe 101 and the one-way nozzle 102 to rotate, thus stirring the wastewater and flocculant in the flocculation chamber 3. This ensures that the flocculant is more evenly distributed in the wastewater and mixes thoroughly with it, resulting in better flocculation. Some impurities generated during flocculation will precipitate in the flocculation chamber. The wastewater flows from the lower side of the flocculation chamber 3 to the slag discharge valve 602 via the slag discharge mechanism 6. The flocculated wastewater flows into the cylinder 7 and is filtered out by the metal filter plate 111 in the filtration mechanism 11. The filtered water flows to the lower side of the filtration chamber 4 and is discharged through the drain valve 16. The filtered impurities remain in the metal filter plate 111 and the cylinder 7, causing the transmission pipe 9 to drive the feeding spiral blade 112 to rotate. The feeding spiral blade 112 moves the impurities toward the right side of the cylinder 7. The feeding spiral blade 112 cleans the impurities on the metal filter plate 111 and the cylinder 7, effectively preventing the metal filter plate 111 from clogging. The impurities fall into the collection box 151 in the collection mechanism 15, thus collecting the filtered impurities and making it more convenient to use.

[0034] In summary, this underground coal mine wastewater treatment device, through the stirring mechanism 10, makes the flocculant distribution more uniform, enabling it to mix more thoroughly with the wastewater and achieve better flocculation. During the filtration process, it can collect the filtered impurities and adds a cleaning function to the filter mechanism 11, effectively preventing the filter mechanism 11 from clogging and making it more convenient to use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
