Description

Technical Field

[0001] The present disclosure relates to the technical field of wastewater filtration in thermal power plants, and in particular to a wastewater filtration device. Background Art

[0002] Thermal power generation, also known as heat power generation, is a process that converts the chemical energy of fuel into heat, then mechanical energy, and finally electrical energy. Thermal power plants offer the advantages of flexible layout, customized installed capacity, relatively short construction periods, low investment, and adaptability to various geographical environments. In related technologies, thermal power generation generates a large amount of wastewater that needs to be filtered before discharge. Because the filter membrane cannot be replaced online during use, prolonged use can lead to clogging of the membrane, thus affecting the filtration effect. Furthermore, if the water inlet pipe remains in one position for a long time, wastewater will impact the filter membrane for a long time, easily damaging it. Utility Model Content

DETAILED DESCRIPTION

[0048] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0049] In the present disclosure, unless otherwise stated, directional words such as "inside" and "outside" refer to the outlines of the corresponding components themselves; "upstream" and "downstream" refer to the flow direction of wastewater; directional words such as "upper", "lower", "top", "bottom", "horizontal" and "vertical" are defined based on the usage habits of the wastewater filtration device provided by the present disclosure. Specifically, please refer to Figure 1 In the illustrated drawings, the side indicated by the Z arrow is the top and upper side, and the opposite direction is the bottom and lower side. Furthermore, the Z direction represents the height of the box, the X direction represents the width of the box, and the Y direction represents the thickness of the box. The X and Y directions represent the horizontal directions, and the Z direction represents the vertical direction. Terms such as "first" and "second" used in this disclosure are intended to distinguish one element from another and do not have a sequential or significant nature. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings represent the same or similar elements.

[0050] Reference Figures 1-9The present disclosure provides a wastewater filtration device, which may include a housing 1 and a water supply part 3, a filter part 2 and a drainage part 4 arranged in sequence from top to bottom. The housing 1 may be constructed to be hollow inside so as to form a receiving space. The filter part 2 may include a filter membrane 21 for filtering wastewater, and the filter membrane 21 may be unfolded in a horizontal direction and pluggably matched with the housing 1, thereby realizing a detachable connection with the housing 1, so that the filter membrane 21 can be replaced in time when there is a need for replacement, avoiding the situation where the filter membrane 21 is damaged due to long-term use, and preventing the filtering effect of the wastewater from being affected. In addition, the staff can configure filter membranes 21 of different specifications according to the filtering requirements of the wastewater to meet the use requirements, thereby effectively improving the versatility of the wastewater filtration device. The water supply part 3 can be located above the filter part 2 and downstream of the filter membrane 21, and the water supply part 3 sprays the wastewater from top to bottom onto the water separation box 31 of the filter membrane 21. When the wastewater is sprayed through the water separation box 31, it can rely on its own gravity to fall to the filter membrane 21, thereby ensuring that the wastewater can be fully filtered and ensuring the filtering effect of the wastewater. The water separation box 31 can be configured to be able to rotate in a horizontal plane relative to the filter membrane 21, that is, it can rotate back and forth in the XY plane, thereby avoiding certain areas of the filter membrane 21 from being broken due to long-term concentration and excessive spraying of wastewater, thereby achieving full utilization and safety of the filter membrane 21, and improving the stability and sustainability of the wastewater filtration device during operation. The drainage portion 4 can be located below the filter membrane 21 and downstream of the filter membrane 21, so as to discharge the wastewater flowing through the filter membrane 21 to other external equipment downstream of the box 1, thereby facilitating the staff to centrally treat and collect the treated wastewater, so as to avoid the accumulation of a large amount of treated wastewater in the box 1 and prevent the internal space of the box 1 from being occupied, so as to ensure the continuous and stable filtration of the wastewater.

[0051] Through the above technical solution, the pluggable design of the filter membrane 21 and the housing 1 makes the replacement and cleaning of the filter membrane 21 more convenient and quick, reducing maintenance costs and time, and preventing the filter membrane 21 from being broken due to long-term use, which affects the filtration effect. In addition, the rotation function of the water diversion box 31 allows the wastewater to be sprayed evenly on the filter membrane 21, preventing certain areas of the filter membrane 21 from being broken due to long-term concentration and excessive spraying of wastewater, thereby improving the filtration uniformity and the service life of the filter membrane 21.

[0052] Reference Figure 1-Figure 3The filter unit 2 may include a first jack 22, a mounting assembly 23, and a support frame 24. The first jack 22 may be provided on the peripheral wall 11 of the housing 1. In the present disclosure, the peripheral wall 11 may include a first side wall 111 arranged in the X direction and a second side wall 112 arranged in the Y direction. The first jack 22 may be provided on the first side wall 111. The mounting assembly 23 may include a first support frame 231. The filter membrane 21 may be detachably laid on the first support frame 231, so that the staff can select a suitable filter membrane 21 according to different wastewater characteristics and replace the filter membrane 21 when the service life is reached, thereby enhancing the adaptability of the wastewater filtration device and the continuity of wastewater filtration. In the embodiment provided in the present disclosure, the outer contour dimensions of the filter membrane 21 and the first support frame 231 may match the inner contour dimensions of the XY plane of the housing 1 to ensure that the wastewater can fully flow through the filter membrane 21 before passing to the downstream. The first support frame 231 can pass through the first insertion hole 22 in the horizontal direction, and then be pluggably connected to the box body 1, so as to be able to drive the filter membrane 21 to be installed in the box body 1 or to be removed from the box body 1 and moved out of the box body 1. The design of the first insertion hole 22 enables the first support frame 231 to be easily inserted into and removed from the box body 1, which greatly simplifies the replacement and maintenance process of the filter membrane 21 and improves the operational convenience of the staff. The support frame 24 can be installed on the inner side of the peripheral wall 11, for example, it can be installed on the second side wall 112. The support frame 24 can be used to support the bottom of the first support frame 231, thereby effectively supporting the first support frame 231 along the Z direction, increasing the stability of the installation of the entire filter unit 2, and reducing the risk of displacement or deformation caused by wastewater impact. Figure 3 As shown, the number of support frames 24 can be two, and the two support frames 24 can be respectively set on two pairs of second side walls 112 to further improve the supporting capacity of the first support frame 231 and improve the reliability and stability of the installation position of the first support frame 231.

[0053] Reference Figure 3 as well as Figure 5-Figure 8 The mounting assembly 23 may further include a second support frame 232, a fixing plate 233, a pressing plate 234, and a push rod 236. The second support frame 232 may be disposed on the top of the support frame 24, and the second support frame 232 may be used to support the first support frame 231 to further improve the stability of the support for the first support frame 231. The fixing plate 233 may be fixedly connected to the outer edge of the second support frame 232. Figure 7The fixing plate 233 can be provided on one side of the second support frame 232 in the X direction to prevent the first support frame 231 from being displaced relative to the second support frame 232 in the X direction. According to some embodiments provided by the present disclosure, there can be two fixing plates 233, and the two fixing plates 233 can be fixed on both sides of the second support frame 232 in the X direction, respectively. In this way, the two fixing plates 233 and the second support frame 232 can jointly form a semi-enclosed structure with a U-shaped interface structure. The first support frame 231 supporting the filter membrane 21 can be confined inside the U-shaped semi-enclosed structure, thereby further improving the stability and reliability of the installation of the first support frame 231 and the filter membrane 21. The pressing plate 234 can be flip-connected to the fixing plate 233 in a vertical plane above the fixing plate 233, and the pressing plate 234 can have a locked position and an unlocked position. The outer edge of the pressing plate 234 can be hinged to the fixing plate 233, and the inner edge of the pressing plate 234 is not connected to the fixing plate 233, so as to be able to be constructed as a hinge structure. In the present disclosure, the locked position refers to the pressing plate 234 and the fixing plate 233 being in a hinged position. Figure 7 In the state shown, the unlocked position refers to the inner edge of the pressing plate 234 being detached from the fixing plate 233 to form an angle with the fixing plate 233. One end of the push rod 236 can be connected to the portion of the pressing plate 234 extending from the fixing plate 233, and the other end of the push rod 236 can extend downward. With this design, when the pressing plate 234 is in the locked position, the other end of the push rod 236 can abut against the first support frame 231, thereby pressing the first support frame 231 downward and locking the first support frame 231 to the second support frame 232, thereby limiting the first support frame 231 in the Z direction and preventing the first support frame 231 from causing relative displacement of the filter membrane 21 when subjected to external force. When the pressing plate 234 is in the unlocked position, the other end of the push rod 236 can be detached from the first support frame 231 to release the first support frame 231, allowing the first support frame 231 to move out and detach from the second support frame 232.

[0054] Reference Figure 5 and Figure 7According to some embodiments provided by the present disclosure, two pressing plates 234 can also be provided. The two pressing plates 234 can be respectively provided above the two fixed plates 233. The sides of the two pressing plates 234 that are away from each other along the X direction can be rotatably connected to the corresponding fixed plates 233 respectively. The sides of the two pressing plates 234 that are close to each other can be formed as free ends so as to be able to be roughly constructed into a hinge structure, and the sides of the two pressing plates 234 that are close to each other can respectively extend from the corresponding fixed plates 233. The push rod 236 can also correspond to the two pressing plates. Two groups of pressure plates 234 are provided, one end of the push rod 236 can be connected to the portion of the corresponding pressure plate 234 extending from the fixed plate 233, and the other end of the push rod 236 extends downward, so that when the pressure plate 234 is in the locked position, the other end of the push rod 236 can abut against the first support frame 231, thereby pressing the first support frame 231 downward and locking the first support frame 231 inside the U-shaped semi-enclosed structure mentioned above, so as to further improve the limiting effect on the first support frame 231, thereby further ensuring the stability of the filter membrane 21 in the box body 1.

[0055] Reference Figure 8 A flexible pad 234b can be provided on the side of the pressing plate 234 close to the fixed plate 233. The flexible pad 234b can be made of rubber material, so as to reduce the wear between the pressing plate 234 and the fixed plate 233, and can play a buffering role when the pressing plate 234 has the automatic reset function mentioned below, thereby effectively improving the service life of the pressing plate 234 and the fixed plate 233.

[0056] Reference Figure 7 and Figure 9 The mounting assembly 23 also includes a second socket 235 formed on the first support frame 231 corresponding to the push rod 236. When in the locked position, the push rod 236 can be inserted into the second socket 235 to further improve the connection strength between the first support frame 231 and the pressing plate 234, thereby improving the stability during the filtration process. When in the unlocked position, the push rod 236 can be pulled out of the second socket 235, so that the first support frame 231 can be detached from the first support frame 231 and avoid interference with the first support frame 231.

[0057] Reference Figure 7 and Figure 8, the mounting assembly 23 may further include a rotating shaft 237 and a torsion spring 238. In the present disclosure, a slot 234a extending along the Y direction may be provided on the pressing plate 234, and the rotating shaft 237 may pass through the slot 234a in the horizontal direction. The rotating shaft 237 may be interference fit with the slot 234a, so that when one of the pressing plate 234 and the rotating shaft 237 rotates, the other can be driven to rotate synchronously. The two ends of the rotating shaft 237 are rotatably inserted into the fixed plate 233 around their own axis, so that the pressing plate 234 can be flipped relative to the fixed plate 233. The two ends of the torsion spring 238 can be fixedly connected to the rotating shaft 237 and the fixed plate 233 respectively. When the pressing plate 234 is in a position such as Figure 7 When in the locked state shown, a force is applied to the pressing plate 234 to drive the pressing plate 234 to rotate to switch to the unlocked state. At this time, the rotating shaft 237 rotates following the rotation of the pressing plate 234. At this time, one end of the torsion spring 238 also rotates and accumulates elastic potential energy. In this way, when the external force applied to the pressing plate 234 is removed, the torsion spring 238 can release the elastic potential energy and drive the rotating shaft 237 to rotate in the opposite direction, thereby driving the pressing plate 234 to rotate in the direction of switching to the locked state, so as to realize the automatic reset of the pressing plate 234.

[0058] Reference Figure 1-Figure 3 The filter unit 2 may further include a baffle 25 and a handle 26. The outer contour of the baffle 25 matches the inner contour of the first insertion hole 22, and the inner side of the baffle 25 corresponds to the first insertion hole 22 and is connected to the second support frame 232. When the second support frame 232 is inserted into the box body 1 through the first insertion hole 22, the baffle 25 can be exactly embedded in the first insertion hole 22 to seal the box body 1, thereby preventing external interference with the normal operation of the wastewater filtration device and preventing foreign matter from entering the box body 1 through the first insertion hole 22. The handle 26 can be set on the outer side of the baffle 25 away from the second support frame 232. When the second support frame 232 needs to be pulled out, the handle 26 can be pulled outward to drive the baffle 25 to pull the second support frame 232 out, which is convenient for the staff to operate. In addition, when the second support frame 232 needs to be inserted, the handle 26 can also be pushed inward to drive the baffle 25 to push the second support frame 232, which not only effectively avoids direct contact with the second support frame 232, but also makes it easier to control the second support frame 232.

[0059] Reference Figure 1 、 Figure 2 as well as Figure 4The water delivery portion 3 further includes a drive motor 32, a driving gear 33, a connecting pipe 34, and a driven gear 35, which are arranged on the top wall 12 of the housing 1. The drive motor 32 can be used to output a driving force for driving the water diversion box 31 to rotate. Specifically, the driving gear 33 can be fixedly connected to the output end of the drive motor 32 to transmit the driving force output by the drive motor 32. The driven gear 35 can mesh with the driving gear 33 and be fixedly sleeved on the outer wall of the connecting pipe 34, so that the driven gear 35 can output the driving force transmitted by the driving gear 33 to the connecting pipe 34, thereby enabling the connecting pipe 34 to rotate around its own axis. By directly sleeved the driven gear 35 on the outer wall of the connecting pipe 34, additional connecting components are reduced, the overall design is simplified, and the compactness of the device is improved. The connecting pipe 34 can be fixedly connected to the water diversion box 31, so that the water diversion box 31 can rotate with the rotation of the connecting pipe 34. The connecting pipe 34 can be connected to an external wastewater tank to pass wastewater into the water diversion box 31, ensuring that the water diversion box 31 continuously sprays wastewater while rotating. In the embodiments provided by the present disclosure, the rotation rate of the water diversion box 31 can be flexibly adjusted by adjusting the speed of the drive motor to adapt to different working requirements.

[0060] Reference Figure 2 and Figure 4 The water diversion box 31 can rotate around the axis of the connecting pipe, and the number of the water diversion boxes 31 can be multiple. The multiple water diversion boxes 31 can extend along the radial direction of the connecting pipe 34 and be arranged at intervals along the circumferential direction. Such a design allows the wastewater flow flowing through the connecting pipe 34 to be more evenly distributed by the multiple water diversion boxes 31, ensuring that the amount of wastewater received by each water diversion box 31 is relatively balanced, enhancing the uniformity and effectiveness of wastewater spraying, and effectively improving the wastewater treatment effect, reducing the load on a certain part of the filter membrane 21, thereby improving the safety of the entire wastewater filtration device and reducing the risk of the filter membrane 21 breaking and the wastewater filtration device failure.

[0061] Reference Figure 2 and Figure 4 The water delivery part 3 also includes a plurality of nozzles 311 arranged on the water separation box 31. The plurality of nozzles 311 are arranged at intervals along the extension direction of the water separation box 31. By setting up a plurality of nozzles 311, the spraying uniformity and spraying efficiency of the wastewater can be further improved, and the situation in which some areas of the filter membrane 21 are over-sprayed while other areas are dry is avoided, thereby achieving full utilization and safety of the filter membrane 21. At the same time, the plurality of nozzles 311 can also disperse the spraying pressure of the water separation box 31 on the wastewater, further reducing the risk of damage to the filter membrane 21, and improving the stability and sustainability of the overall wastewater filtration device during operation.

[0062] Reference Figure 1 and Figure 2According to some embodiments provided by the present disclosure, the water delivery unit 3 further includes a water inlet pipe 36 made of a flexible material. The water inlet pipe 36 can be connected between the external wastewater tank and the connecting pipe 34 to pass the wastewater into the water diversion box 31. The flexible material enables the water inlet pipe 36 to adapt to different working environments and space limitations, making it easy to arrange in various working conditions, and can quickly adapt to different layout requirements, thereby improving the flexibility of installation. Figure 1 The wastewater filtering device may further include an adapter 37. The adapter 37 may be fixedly connected to one end of the water inlet pipe 36 for docking with the connecting pipe 34. An internal thread may be formed on the adapter 37, and an end of the connecting pipe 34 away from the water diversion box 31 may be formed with an external thread that can cooperate with the adapter 37. In this way, the water inlet pipe 36 and the connecting pipe 34 can be detachably connected through the connector 37. At the same time, the connection strength between the water inlet pipe 36 and the connecting pipe 34 can be ensured, thereby avoiding wastewater leakage and ensuring smooth transportation of wastewater.

[0063] Reference Figure 1-Figure 3 The drainage portion 4 may include a drain port 41 and a drain pipe 42. The drain port 41 may be formed on the bottom wall 13 of the housing 1, so that the wastewater can flow directly to the drain port 41 after passing through the filter membrane 21, thereby improving the discharge efficiency of the filtered wastewater and avoiding water accumulation at the bottom of the housing 1. One end of the drain pipe 42 is connected to the drain port 41, and the other end of the drain pipe 42 extends to the outside of the housing 1. In the embodiment provided in the present disclosure, the end of the drain pipe 42 extending from the housing 1 may be connected to other equipment to facilitate the unified collection and treatment of the filtered wastewater.

[0064] Reference Figure 1-Figure 3 The bottom wall 13 of the box body 1 can be provided with a plurality of support legs 5 at intervals, so that the bottom wall 13 can be kept away from the ground and spaced apart from the ground. This not only facilitates the arrangement of the drain pipe 42 but also prevents the bottom wall 13 from directly contacting the ground, effectively preventing wear of the box body 1. In the embodiment provided by the present disclosure, the lower ends of the support legs 5 can be fixed with anti-slip pads to improve the stability and safety of the box body 1 in the installed position.
