Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a water filtration device. Background Technology

[0002] In coal and rock tunneling operations, drainage is a crucial and indispensable aspect. Because the process generates a large amount of water, if it is not drained promptly, the work site will remain damp and waterlogged for extended periods. Therefore, a drainage system is typically installed at the coal and rock tunneling site.

[0003] However, in practice, impurities such as coal slag and rock fragments carried in the gushing water can easily clog the filter screens in the drainage pipes. Once a blockage occurs, workers need to disassemble and clean the filter screens, and then reinstall them, which consumes a lot of manpower and time, thus reducing the continuity of drainage. Utility Model Content

[0004] The main objective of this invention is to provide a water filtration device that improves the continuity of drainage.

[0005] To achieve the above objectives, this utility model proposes a water filtration device, comprising a split first housing and a second housing. The top of the second housing is provided with a water inlet pipe. The first housing and the second housing are fixedly connected by several connecting brackets. Both the first housing and the second housing are provided with annular slide rails on opposite sides. A rotating plate is also provided between the first housing and the second housing, and the rotating plate is disposed between the two annular slide rails and rotatably connected to the annular slide rails. Several filter screens are provided on the rotating plate. The interior of the water inlet pipe is connected to one of the filter screens. The interior of the first housing is provided with a water outlet pipe, and the interior of the water outlet pipe corresponds to the interior of the water inlet pipe. A switching mechanism is provided on the side of the first housing to drive the rotating plate to rotate and switch between the various filter screens.

[0006] In one possible implementation, the switching mechanism includes a gear ring disposed on the outer surface of the rotating plate and fixedly connected to the rotating plate, a gear meshing with the gear ring, and a rotary motor. The inlet pipe and the outlet pipe are both fixedly connected to a sealing block on the side near the rotating plate, and the surface of the sealing block abuts against the rotating plate. The rotary motor is disposed on the side of the first housing and fixedly connected to the first housing, and the output end of the rotary motor is fixedly connected to the gear.

[0007] In one possible implementation, each of the two annular slide rails has an annular guide groove on one side facing each other, and each of the rotating plate has an annular guide block on both sides, with each annular guide block rotatably connected to the inner wall of the corresponding annular guide groove. In one possible implementation,

[0008] In one possible implementation, the inner wall of the annular guide groove is provided with a plurality of balls, and one side of each ball is in rolling connection with the annular guide block.

[0009] In one possible implementation, the first housing is further provided with a cleaning assembly for rinsing the filter screen. The cleaning assembly includes a liquid distributor, a cleaning pipe, and a discharge pipe. The liquid distributor is disposed on the water outlet pipe and is connected to the interior of the liquid distributor. One end of the cleaning pipe is disposed on the water outlet of the liquid distributor, and the other end of the cleaning pipe is connected to the filter screen on the rotating plate away from the water outlet pipe. The discharge pipe is disposed on the side of the rotating plate near the second housing, and the position of the discharge pipe corresponds to the position of the cleaning pipe. The opposite sides of the discharge pipe and the cleaning pipe respectively abut against the two sides of the rotating plate.

[0010] In one possible implementation, the discharge pipe extends through the side of the second housing away from the rotating plate and extends to the outside of the second housing, and a collection box is also provided outside the second housing, with the discharge pipe communicating with the interior of the collection box.

[0011] In one possible implementation, the water inlet pipe is equipped with a first solenoid valve, and the cleaning pipe is equipped with a second solenoid valve.

[0012] This utility model's technical solution, through the setting of a rotating plate, a switching mechanism, and several filter screens, allows for quick switching to other unblocked filter screens to continue drainage when a filter screen is blocked by coal slag or rock chips. Unlike traditional methods, there is no need for manual disassembly and cleaning of the filter screens, which greatly saves manpower and time, ensures the continuity of drainage, and thus improves practicality.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] This utility model proposes a water filtration device, with reference to... Figure 1-5 The system includes a split first housing 1 and a second housing 101. The top of the second housing 101 is provided with a water inlet pipe 1011. The first housing 1 and the second housing 101 are fixedly connected by several connecting brackets 102. Both the first housing 1 and the second housing 101 are provided with annular slide rails 103 on opposite sides. A rotating plate 104 is also provided between the first housing 1 and the second housing 101. The rotating plate 104 is located between the two annular slide rails 103 and is rotatably connected to the annular slide rails 103. The two sides of the connecting brackets 102 can be fixedly connected to the first housing 1 and the second housing 101 respectively by bolts. The bolt connection allows workers to disassemble the first housing 1 and the second housing 101, and allows users to disassemble the rotating plate 104 so that users can replace or repair the filter screen 105.

[0023] The rotating plate 104 is provided with several filter screens 105. The interior of the water inlet pipe 1011 is connected to one of the filter screens 105. The interior of the first housing 1 is provided with a water outlet pipe 106, which is used to connect to the drainage pipe. The interior of the water outlet pipe 106 corresponds to the interior of the water inlet pipe 1011. The side of the first housing 1 is a switching mechanism for driving the rotating plate 104 to rotate so that the filter screens 105 can be switched.

[0024] The switching mechanism includes a gear ring 2 fixedly connected to and disposed on the outer surface of the rotating plate 104, a gear 201 meshing with the gear ring 2, and a rotary motor 202. Sealing blocks 203 are fixedly connected to the sides of the water inlet pipe 1011 and the water outlet pipe 106 near the rotating plate 104, and the surfaces of the sealing blocks 203 abut against the rotating plate 104. A hard seal is used between the sealing blocks 203 and the rotating plate 104. The rotary motor 202 is disposed on the side of the first housing 1 and fixedly connected to it. The output end of the rotary motor 202 is fixedly connected to the gear 201. The rotary motor 202 can be fixedly connected to the side of the first housing 1 by bolts.

[0025] The rotating plate 104 can be made of aluminum alloy. Aluminum alloy has a low density and is lightweight, allowing it to withstand a certain load. During rotation, the lightweight material helps reduce friction. Secondly, an elastic sealing ring can be installed between the sealing block 203 and the rotating plate 104. This sealing ring ensures a tight connection between the two, preventing water leakage. Simultaneously, lubricant can be applied to the contact surfaces of the rotating plate 104 and the sealing block 203 to reduce the coefficient of friction and ensure smooth rotation.

[0026] When one of the filter screens 105 becomes clogged, the rotary motor 202 is activated. The output of the rotary motor 202 drives the gear 201 to rotate, which in turn drives the gear ring 2 to rotate. The gear ring 2 then drives the rotating plate to rotate, which in turn rotates the clogged filter screen 105 (during this process, the sealing block 203 remains stationary) until the next new filter screen 105 is connected to the inlet pipe 1011. Through the transmission of the gear 201 and the gear ring 2 in conjunction with the drive of the rotary motor 202, the switching of the filter screen 105 is automated, thereby reducing the time required for workers to switch the filter screen 105.

[0027] Furthermore, the rotation angle of the rotating plate 104 is related to the number of filter screens 105. For example, if there are six filter screens 105, the rotary motor 202 drives the rotating plate 104 to rotate 60 degrees; if there are eight filter screens 105, the rotary motor 202 drives the rotating plate 104 to rotate 45 degrees, and so on. It should be noted that how to use the rotary motor 202 to drive the rotating plate 104 to rotate to the corresponding angle is prior art well known to those skilled in the art, and therefore will not be described in detail.

[0028] During the rotation of the rotating plate 104, the continuous inflow of water through the inlet pipe 1011 creates significant water pressure on its surface, resulting in a heavy load on the plate. Over time, this can cause deformation of the rotating plate 104, reducing its lifespan. To prevent this, a first solenoid valve 304 can be installed on the inlet pipe 1011. When the rotating plate 104 rotates, the user can close this valve, sealing the inside of the inlet pipe 1011 and preventing water pressure from acting on the surface of the rotating plate 104, thereby extending its lifespan.

[0029] Furthermore, annular guide grooves 204 are provided on opposite sides of the two annular slide rails 103, and annular guide blocks 205 are provided on both sides of the rotating plate 104. Each annular guide block 205 is rotatably connected to the inner wall of the corresponding annular guide groove 204. The nested structure of the annular guide grooves 204 and the annular guide blocks 205 provides precise radial positioning for the rotating plate 104, preventing offset during rotation and thus improving the stability of the rotating plate 104 during rotation.

[0030] Meanwhile, a number of balls 206 are also provided on the inner wall of the annular guide groove 204. One side of each ball 206 is rolledly connected to the annular guide block 205. The ball 206 structure converts sliding friction into rolling friction, which reduces the energy consumption of the rotary motor 202 and reduces the friction between the annular guide groove 204 and the annular guide block 205, making the rotating plate 104 rotate more smoothly.

[0031] In this embodiment, the first housing 1 is further provided with a cleaning assembly for rinsing the filter screen 105. The cleaning assembly includes a liquid distributor 3 (the liquid distributor 3 can distribute the liquid flow from one inlet to multiple outlet channels as needed, ensuring that the liquid can flow to multiple target locations simultaneously), a cleaning pipe 301, and a discharge pipe 302. The liquid distributor 3 is disposed on the water outlet pipe 106 and the water outlet pipe 106 is connected to the interior of the liquid distributor 3. One end of the cleaning pipe 301 is disposed on the water outlet of the liquid distributor 3, and the other end of the cleaning pipe 301 is connected to the filter screen 105 on the rotating plate 104 away from the water outlet pipe 106. The discharge pipe 302 is disposed on the side of the rotating plate 104 near the second housing 101, and the position of the discharge pipe 302 corresponds to the position of the cleaning pipe 301. The opposite sides of the discharge pipe 302 and the cleaning pipe 301 respectively abut against the two sides of the rotating plate 104.

[0032] When water flows through the inlet pipe 1011 and through the filter screen 105 into the outlet pipe 106, the liquid distributor 3 on the outlet pipe 106 distributes the liquid to multiple outlet channels, thereby introducing the water flow into the cleaning pipe 301. Subsequently, the cleaning pipe 301 backwashes the switched and clogged filter screen 105, and the particles and impurities on the filter screen 105 are discharged through the discharge pipe 302. This design completes the cleaning of the filter screen 105 without stopping the machine and without requiring an additional power source. At the same time, the backwashing, by flushing the surface of the filter screen 105 with reverse water flow, can effectively remove dirt, deposits and other impurities on the filter screen 105, keeping the filter screen 105 clean and thus restoring its filtration efficiency. Secondly, a booster pump can be installed at the inlet pipe 1011 to increase the water pressure and ensure that the water flow can smoothly enter the cleaning pipe 301 and backwash the filter screen 105.

[0033] To collect water and impurities flowing from the discharge pipe 302, the side of the discharge pipe 302 away from the rotating plate 104 passes through the side of the second housing 101 and extends to its exterior. A collection box 303 is also provided on the exterior of the second housing 101, and the discharge pipe 302 communicates with the interior of the collection box 303. The collection box 303 can collect wastewater and impurities generated during the cleaning process, helping to maintain a clean working environment.

[0034] Next, as water continues to flow into the inlet pipe 1011, the liquid distributor 3 guides the water flow from the outlet pipe 106 to the cleaning pipe 301, causing the cleaning pipe 301 to continuously clean the filter screen 105. Over time, this not only wastes water but may also damage the filter screen 105. To avoid this, a second solenoid valve 305 can be installed on the cleaning pipe 301. This valve controls the flow of water within the cleaning pipe 301, allowing workers to determine whether cleaning of the filter screen 105 is necessary based on the actual situation. This reduces water waste, lowers the risk of filter screen damage, and improves the equipment's usability.
