Description

Technical Field

[0001] This invention belongs to the field of mine well water testing technology, specifically a pretreatment device for mine well water testing. Background Technology

[0002] Mine water is formed during coal mining when groundwater comes into contact with coal seams and rock strata, and is also affected by human activities, resulting in a series of physical, chemical, and biochemical reactions. Currently, to detect the specific composition of mine water, a certain amount of mine water needs to be extracted and then sent as a test sample.

[0003] When extracting mine water, it typically contains various particulate impurities, such as slag and gravel. To prevent these impurities from affecting subsequent testing, they need to be removed beforehand. Traditional methods often involve passing the mine water through a container or pipe with a filter after extraction, using the filter to intercept and remove the impurities. However, when the sample size is large, more water needs to be processed. As the water passes through the filter, more impurities are intercepted on one side, easily causing clogging. Therefore, existing technologies require periodically opening the container to clean the filter to ensure effective filtration. However, cleaning the filter requires stopping the filtration process, impacting the overall treatment efficiency. Summary of the Invention

Several evenly distributed air blowing holes are opened on the two side walls of the air blowing box facing the inner wall of the annular filter belt.

[0009] As a further improvement to the present invention: the air blowing assembly further includes a piston cylinder, an air supply pipe, and an air replenishment pipe. The piston cylinder is located outside the cleaning top box. One end of the air supply pipe is fixedly connected to the air blowing box, and the other end extends to the outside of the cleaning top box and is fixedly connected to the piston cylinder. The air replenishment pipe is installed on the side wall of the piston cylinder. Both the air replenishment pipe and the air supply pipe are equipped with one-way valves. A first rotating shaft is fixedly installed at the end of the belt roller located inside the cleaning top box. The end of the first rotating shaft away from the belt roller extends to the outside of the cleaning top box and is fixedly installed with an eccentric pressure roller. The air supply assembly includes a piston rod, an annular stop, an elastic element, and a piston block. The piston block is movably disposed inside the piston cylinder. One end of the piston rod is fixedly connected to the piston block, and the other end extends above the piston cylinder and contacts the circumferential side wall of the eccentric pressure roller. The annular stop block is fixedly disposed outside the piston rod. One end of the elastic element is connected to the annular stop block, and the other end is connected to the piston cylinder, for providing elastic support for the piston rod.

[0010] As a further improvement of the present invention: the elastic element is a spring or a metal sheet.

[0011] As a further improvement of the present invention: the bottom of the piston cylinder is fixedly connected to the outer wall of the cleaning top box by a support.

[0012] As a further improvement of the present invention: the cleaning top box is also provided with a striking component, which is used to strike the annular filter belt, thereby causing the annular filter belt to shake.

[0014] As a further improvement of the present invention: cleaning ports are provided on the two opposite side walls of the cleaning top box that are parallel to the annular filter belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this embodiment of the invention, when pretreatment of mine water is required, the mine water can be introduced into the treatment tank through the inlet pipe. After entering the treatment tank, the mine water flows along the inside of the tank and is discharged through the outlet pipe. During this process, the mine water passes through the strip filter assembly, which intercepts particulate impurities in the mine water, thus achieving filtration treatment. In the above process, the strip filter assembly is driven to rotate by the drive assembly. When the strip filter assembly rotates, the particulate impurities intercepted on its outer wall are continuously transferred to the cleaning top box, and then utilized... Air is supplied to the air blowing assembly by the air supply assembly. The air is then blown to the strip filter assembly, which removes particulate matter from the outer wall of the strip filter assembly, thus automatically cleaning the particulate matter and preventing it from clogging the strip filter assembly. This allows the strip filter assembly to continuously filter mine water, improving the treatment efficiency of mine water. Compared with existing technologies, this technology can achieve automatic filtration of mine water, and the strip filter assembly can be automatically cleaned online without stopping the machine during the filtration process. It has the advantages of good filtration effect and high filtration efficiency for mine water. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This embodiment provides a pretreatment device for mine water testing, including a treatment box 10, a cleaning top box 20, a strip filter assembly 30, a drive assembly 40, an air supply assembly 50, and an air blowing assembly 60. The treatment box 10 has an inlet pipe 101 on one upper side and an outlet pipe 102 on the other lower side. The cleaning top box 20 is fixedly installed on the upper part of the treatment box 10. One end of the strip filter assembly 30 extends to the bottom of the inner side of the treatment box 10, and the other end extends to the inner side of the cleaning top box 20, for filtering the mine water flowing inside the treatment box 10. The drive assembly 40 is installed on the side of the cleaning top box 20. On the wall, a device is used to drive the strip filter assembly 30 to rotate, so as to transfer the particulate matter intercepted on the side wall of the strip filter assembly 30 to the inside of the cleaning top box 20. One end of the air blowing assembly 60 extends into the inside of the cleaning top box 20 and is located inside the strip filter assembly 30, and the other end extends to the outside of the cleaning top box 20. The air supply assembly 50 is installed outside the cleaning top box 20 and is used to supply air to the air blowing assembly 60. The air blowing assembly 60 blows the air from the air supply assembly 50 toward the strip filter assembly 30, so as to blow the particulate matter transferred to the inside of the cleaning top box 20 away from the outer wall of the strip filter assembly 30.

[0023] When pretreatment of mine water is required, the mine water can be introduced into the treatment tank 10 through the inlet pipe 101. After entering the treatment tank 10, the mine water flows along the inside of the treatment tank 10 and is discharged from the outlet pipe 102. During this process, the mine water passes through the strip filter assembly 30, which intercepts particulate impurities in the mine water, thus achieving filtration treatment. In the above process, the drive assembly 40 drives the strip filter assembly 30 to rotate. When the strip filter assembly 30 rotates, the particulate impurities intercepted on its outer wall are continuously transferred to the cleaning top box 20. Then, the air supply assembly 50 supplies air to the air blowing assembly 60. The air is blown to the strip filter assembly 30 through the air blowing assembly 60, thereby blowing away the particulate impurities on the outer wall of the strip filter assembly 30, realizing automatic cleaning of particulate impurities, thus avoiding the blockage of the strip filter assembly 30 by particulate impurities, so that the strip filter assembly 30 can continuously filter the mine water and improve the treatment efficiency of the mine water.

[0024] Please see Figure 4 , Figure 5 , Figure 6 as well as Figure 7In one embodiment, the drive assembly 40 includes a belt roller 401 and a drive motor 404. The belt roller 401 is provided in two sets, one set of which is rotatably disposed on the top inner side of the cleaning top box 20, and the other set of which is rotatably disposed on the bottom inner side of the processing box 10. The drive motor 404 is fixedly installed on the outer wall of the cleaning top box 20 and is used to drive the belt roller 401 located inside the processing box 20 to rotate. The strip filter assembly 30 includes an annular filter belt 301. The annular filter belt 301 has a plurality of evenly distributed filter holes 302 on its side wall. The annular filter belt 301 is sleeved on the outside of the two sets of belt rollers 401. The top wall of the processing box 10 has an opening 103 for communicating with the inner cavity of the cleaning top box 20 and the inner cavity of the processing box 10. The annular filter belt 301 passes through the opening 103.

[0025] As the mine water flows along the inside of the treatment box 10, it passes through several filter holes 302 and onto the annular filter belt 301. At this time, particulate impurities in the mine water are intercepted on the outer wall of the annular filter belt 301, thereby achieving the filtration treatment of the mine water. During the filtration process, the drive motor 404 drives the belt roller 401 located inside the cleaning top box 20 to rotate. When the belt roller 401 rotates, it acts as the active roller, and the belt roller 401 located at the bottom of the inner side of the treatment box 10 acts as the driven roller. The active roller and the driven roller rotate synchronously, thereby driving the annular filter belt 301 to rotate. When the annular filter belt 301 rotates, the particulate impurities intercepted on its outer wall are lifted upward by the friction of the annular filter belt 301 and thus transferred to the inside of the cleaning top box 20.

[0026] Please see Figure 5 In one embodiment, a plurality of limiting baffles 303 are fixedly provided on the outer wall of the annular filter belt 301 at intervals.

[0027] As the annular filter belt 301 rotates and lifts particulate matter upwards, some particulate matter may not be lifted by the annular filter belt 301 due to low friction with it. In this case, the particulate matter can fall on the upper part of the limiting block 303 and be blocked by the limiting block 303. The limiting block 303 drives the particulate matter into the cleaning top box 20, thus achieving the smooth transfer of particulate matter.

[0028] In one embodiment, both the limiting strip 303 and the annular filter belt 301 are made of rubber, and the limiting strip 303 and the annular filter belt 301 are integrally formed.

[0029] Please see Figure 6In one embodiment, the air blowing assembly 60 includes an air blowing box 602, which is disposed inside the annular filter belt 301. The air blowing box 602 is fixedly connected to the inner wall of the cleaning top box 20. A plurality of evenly distributed air blowing holes 605 are provided on the two side walls of the air blowing box 602 facing the inner wall of the annular filter belt 301.

[0030] After the annular filter belt 301 rotates to transfer particulate debris into the cleaning top box 20, the air supply component 50 supplies air into the air blowing box 602. The air is output through several air blowing holes 605 on the two side walls of the air blowing box 602 and acts on the inner walls of both sides of the annular filter belt 301. Then the air passes through several filter holes 302 on the annular filter belt 301 corresponding to the positions of the air blowing box 602, thereby blowing away the particulate debris on the outer wall of the annular filter belt 301, realizing the automatic cleaning of the annular filter belt 301. After the annular filter belt 301 is cleaned, it continues to rotate into the mine water body inside the treatment box 10, and then filters the subsequent mine water.

[0031] Please see Figure 6 as well as Figure 7 In one embodiment, the air blowing assembly 60 further includes a piston cylinder 601, an air supply pipe 603, and an air replenishment pipe 604. The piston cylinder 601 is disposed outside the cleaning top box 20. One end of the air supply pipe 603 is fixedly connected to the air blowing box 602, and the other end extends to the outside of the cleaning top box 20 and is fixedly connected to the piston cylinder 601. The air replenishment pipe 604 is installed on the side wall of the piston cylinder 601. Both the air replenishment pipe 604 and the air supply pipe 603 are provided with one-way valves (not shown in the figure). A first rotating shaft 402 is fixedly disposed at the end of the belt roller 401 located inside the cleaning top box 20. The first rotating shaft 402 is away from the belt roller 401. One end of 01 extends to the outside of the cleaning top box 20 and is fixedly provided with an eccentric pressure roller 403. The air supply assembly 50 includes a piston rod 501, an annular stop block 502, an elastic element 503 and a piston block (not shown in the figure). The piston block is movably disposed inside the piston cylinder 601. One end of the piston rod 501 is fixedly connected to the piston block, and the other end extends above the piston cylinder 601 and contacts the circumferential side wall of the eccentric pressure roller 403. The annular stop block 502 is fixedly disposed outside the piston rod 501. One end of the elastic element 503 is connected to the annular stop block 503, and the other end is connected to the piston cylinder 601, for providing elastic support for the piston rod 501.

[0032] When the drive motor 404 drives the belt roller 401 to rotate, thereby driving the annular filter belt 301 to rotate, the belt roller 401 can also drive the first rotating shaft 402 and the eccentric pressure roller 403 to rotate. When the eccentric pressure roller 403 rotates, its circumferential sidewall acts on the piston rod 501. Combined with the elastic support of the elastic element 503 for the piston rod 501, the piston rod 501 can move up and down. When the piston rod 501 moves up and down, it drives the piston block to move up and down along the inside of the piston cylinder 601. When the piston block moves down, the one-way valve inside the air supply pipe 603 opens, and the one-way valve inside the air replenishment pipe 604 closes. The piston block draws air from the inside of the piston cylinder 601 through the air supply pipe 603. 3. The air is compressed into the air blowing box 602 and then output through several air blowing holes 605 on the two side walls of the air blowing box 602, which act on the inner walls of the two sides of the annular filter belt 301. The air passes through the filter holes 302 on the annular filter belt 301 corresponding to the positions of the air blowing box 602, thereby blowing away the particulate impurities attached to the outer wall of the annular filter belt 301, realizing the automatic cleaning of the annular filter belt 301. When the piston block moves upward along the inside of the piston cylinder 601, the one-way valve inside the air supply pipe 603 closes and the one-way valve inside the air replenishment pipe 604 opens. The piston block draws outside air into the piston cylinder 601 through the air replenishment pipe 604, realizing the replenishment of air.

[0033] In one embodiment, the elastic element 503 can be a spring or a metal sheet, and there is no limitation on this.

[0034] Please see Figure 5 In one embodiment, the bottom of the piston cylinder 601 is fixedly connected to the outer wall of the cleaning top box 20 via a support 606.

[0035] Please see Figure 7 In one embodiment, the cleaning top box 20 is further provided with a tapping component 70, which is used to tap the annular filter belt 301, thereby causing the annular filter belt 301 to shake. After the annular filter belt 301 transfers particulate debris into the cleaning top box 20, the particulate debris attached to the outer wall of the annular filter belt 301 can be quickly detached due to the shaking of the annular filter belt 301. Combined with the airflow passing through the filter holes 302, the cleaning effect of particulate debris can be improved.

[0036] Please see Figure 7In one embodiment, the tapping assembly 70 includes a second rotating shaft 701, tapping plates 702, and a transmission gear 703. One end of the second rotating shaft 701 extends to the inner side of the annular filter belt 301, and the other end passes through the side wall of the cleaning top box 20 and extends to the outside of the cleaning top box 20. The second rotating shaft 701 is rotatably connected to the cleaning top box 20. The transmission gear 703 is fixedly disposed at the end of the second rotating shaft 701 located outside the cleaning top box 20. Several sets of tapping plates 702 are provided, and several tapping plates 702 are fixedly disposed on the shaft body of the second rotating shaft 701 located inside the annular filter belt 301. A transmission rack 504 is fixedly disposed on the side wall of the piston rod 501. The transmission rack 504 extends to one side of the transmission gear 703 and meshes with the transmission gear 703.

[0037] When the eccentric pressure roller 403 and the elastic element 503 cooperate to drive the piston rod 501 to move up and down, the piston rod 501 drives the transmission rack rod 504 to move up and down synchronously. When the transmission rack rod 504 moves up and down, it drives the second rotating shaft 701 to reciprocate through meshing with the transmission gear 703. When the second rotating shaft 701 reciprocates, it drives several striking plates 702 to reciprocate. When the several striking plates 702 reciprocate, they strike the inner wall of the annular filter belt 301, thereby causing the annular filter belt 301 to shake, so that the particulate debris attached to the outer wall of the annular filter belt 301 is quickly removed, improving the cleaning effect of the annular filter belt 301.

[0038] Please see Figure 1 as well as Figure 2 In one embodiment, cleaning ports 201 are provided on two opposite side walls of the cleaning top box 20 that are parallel to the annular filter belt 301.

[0039] When the airflow passes through the filter hole 302 and blows away the particulate matter on the outer wall of the annular filter belt 301, the particulate matter can fall onto the processing box 10 through the cleaning port 201. The staff can then clean the particulate matter on the processing box 10 regularly.

[0040] In this embodiment of the invention, when pretreatment of mine water is required, the mine water can be introduced into the treatment tank 10 through the inlet pipe 101. After entering the treatment tank 10, the mine water flows along the inside of the treatment tank 10 and is discharged from the outlet pipe 102. During this process, the mine water passes through the strip filter assembly 30, which intercepts particulate impurities in the mine water, thereby achieving filtration treatment of the mine water. In the above process, the drive assembly 40 drives the strip filter assembly 30 to rotate. When the strip filter assembly 30 rotates, the particulate impurities intercepted on its outer wall are continuously transferred to the cleaning top box 20. Then, the air supply component 50 supplies air to the air blowing component 60. The air is blown by the air blowing component 60 to the strip filter component 30, thereby blowing away the particulate matter on the outer wall of the strip filter component 30, realizing automatic cleaning of particulate matter, thus preventing particulate matter from clogging the strip filter component 30. This allows the strip filter component 30 to continuously filter mine water, improving the treatment efficiency of mine water. Compared with the existing technology, it can realize automatic filtration treatment of mine water, and the strip filter component 30 can be automatically cleaned online without stopping the machine during the filtration process. It has the advantages of good filtration effect and high filtration efficiency of mine water.
