Description

A solid-liquid separation auxiliary treatment device for industrial wastewater that facilitates filter plate replacement. Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to an auxiliary treatment device for solid-liquid separation of industrial wastewater that facilitates filter plate replacement. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to purify wastewater, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources. Solid-liquid separation is one of the more important preliminary treatment methods in industrial wastewater treatment.

[0003] After searching, the existing technology announcement number CN221491605U describes a solid-liquid separation device for anti-clogging industrial wastewater treatment. This utility model has an anti-clogging structure. Industrial wastewater enters the upper part of the coarse filter screen through the feed inlet for the first filtration, so that the suspended impurities in the industrial wastewater are retained on the upper part of the coarse filter screen. Then, it enters the interior of the metal filter screen for the second filtration, and then enters the interior of the activated carbon layer for the final filtration.

[0004] The anti-clogging mechanism includes a coarse filter, a metal filter, and an activated carbon layer all set together. Therefore, replacing any one of these components requires pulling out the coarse filter, metal filter, and activated carbon layer simultaneously. Furthermore, because the components are arranged from top to bottom, their filtration composition, filtration effect, and impurity content are all different. This results in a situation where, regardless of whether the need to replace the coarse filter, metal filter, and activated carbon layer is different, the entire unit must be pulled out, leading to unnecessary work and wasted filtration resources. Moreover, the replacement process is cumbersome and inconvenient, as disassembly and replacement involve multiple steps.

[0005] The prior art, patent number CN217829130U, describes a solid-liquid separation device for industrial wastewater treatment. In this device, the user can rotate the fixing bolt to disengage the connection between the squeezing plate and the squeezing spring, and then remove the squeezing plate and the fixing plate from the filter plate. However, the replacement of the filter plate in this solution is more cumbersome and has the same technical drawbacks as the aforementioned prior art. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an auxiliary treatment device for solid-liquid separation industrial wastewater that facilitates filter plate replacement. It can achieve stable and orderly independent replacement of filter plates without interfering with the normal operation of other mechanisms through the assistance of the replacement mechanism, which is efficient and fast.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A solid-liquid separation auxiliary treatment device for industrial wastewater with easy filter plate replacement includes a housing, a filter plate, and a replacement mechanism. The filter plate is disposed inside the housing, and the replacement mechanism is disposed on the outer wall of the housing for assisting in the replacement of the filter plate. The filter plate includes a mounting frame and a filter screen mounted on the mounting frame, with grooves on both sides of the mounting frame. The housing has an inlet and an outlet on both sides. A sealing mechanism is provided at both the inlet and outlet for sealing the inlet and outlet. The top of the housing has an inlet pipe, and the bottom has an outlet pipe and support legs. The inner wall of the housing has a support groove for inserting the filter plate. The side wall on the outlet side of the housing has a support plate for supporting the withdrawn filter plate.

[0009] The replacement mechanism includes a carrier box, a support mechanism, and a pushing mechanism. The carrier box is used to load the filter plates. The carrier box has a third through groove on both sides. The bottom of the carrier box has a first through groove and a second through groove. The pushing mechanism is located on one side of the carrier box. One side of the carrier box has an opening, and the inner wall of the other side has an installation groove. The support mechanism is located above the pushing mechanism. The carrier box carries the filter plates, the support mechanism supports the filter plates to fall down in sequence, and the pushing mechanism pushes the filter plates into the carrier box and pushes the internal filter plates out of the carrier box to complete the replacement.

[0010] The support mechanism includes a first push plate, a support plate, and a top plate. The first push plate, support plate, and top plate are located in an installation groove. A guide shaft and a support frame are located on one side of the first push plate. The guide shaft is slidably connected to the side wall of the bearing box and the support frame. The support frame is fixed to the side wall of the bearing box. A limiting plate and a sleeved spring are fixedly connected on the guide shaft. The spring contacts the limiting plate and the support frame. A connecting arm is located at the end of the guide shaft. A connecting rod is located at the end of the connecting arm. An adjusting shaft is located on the connecting rod. The adjusting shaft is movably connected to the support arm. A rotating shaft and an adjusting groove are located on the support arm. The adjusting shaft is located in the adjusting groove. The support arm is located in a third through groove. The support arm is rotatably connected to the installation plate through the rotating shaft. The installation plate is fixedly connected to the side wall of the bearing box.

[0011] The pushing mechanism includes a third push plate and a first electric push rod. The third push plate is located in a mounting groove, and the first electric push rod is fixed to the bottom of the bearing box via a mounting base. The third push plate is provided with a fixedly connected limiting shaft and a second push plate. The limiting shaft is located in a first through groove, and the second push plate is located in a second through groove. The top shaft of the first electric push rod is fixedly connected to the second push plate. The first electric push rod pushes the second push plate and the third push plate to slide. The third push plate is located below the support plate and on one side of the top plate. The pushing stroke of the first electric push rod is sufficient to push the third push plate into the inlet of the box, so that the filter plate is completely inserted into the box.

[0012] The sealing mechanism includes a second electric push rod, a sealing plate, and a limiting frame. The limiting frame and the second electric push rod are fixed to the side wall of the housing. The two ends of the sealing plate are located inside the limiting frame. The top shaft of the second electric push rod is fixedly connected to the sealing plate. The sealing plate is pulled up and down along the limiting frame by the second electric push rod to close and open the inlet and outlet. The sealing plate has a sealing gasket on its side, which can tightly adhere to the side wall of the housing to seal the outlet and inlet and prevent overflow.

[0013] Furthermore, an observation window is provided on the side wall of the chamber to observe the filtration status inside the chamber and make a decision to replace the filter plate based on the filtration status.

[0014] Furthermore, trays are provided at the outlet and inlet to increase the support area with the filter plate and enhance stability.

[0015] Furthermore, the filter plate is provided with a water inlet groove, which guides wastewater to flow away along the water inlet groove when the filter plate is in contact with and supported by the support plate.

[0016] The side wall of the bearing box is provided with a support shaft for supporting the connecting rod.

[0017] Furthermore, the support plate is equipped with a conveying mechanism, including a second motor, a second support plate, a roller shaft, and a conveyor belt. The second support plate is fixedly connected to the support plate, and the two ends of the roller shaft are rotatably connected to the second support plate. The conveyor belt is mounted on the roller shaft, and the second motor is fixed to the side wall of the housing. A sprocket is provided at the end of the roller shaft, and a sprocket is provided at the end of the second motor shaft. The second motor, in conjunction with the sprocket and chain, is connected to the roller shaft for power transmission. The second motor provides power to drive the conveyor belt. The conveying technology of this mechanism is a conventional existing conveying technology, which will not be elaborated on here.

[0018] Furthermore, the support plate is equipped with a stop to restrict the filter plate and facilitate its transfer.

[0019] The advantages of this utility model compared with the prior art are as follows:

[0020] The mechanism in this invention can assist in the replacement of filter plates and is suitable for use in large-scale solid-liquid separation equipment. When replacing filter plates, the replacement mechanism first pushes the filter plate with a pushing mechanism, while the supporting mechanism supports the upper filter plate simultaneously. The supporting mechanism ensures that the upper filter plate does not fall irregularly during the pushing process, i.e., one side falls first, thus preventing any impact or interference with the resetting and retraction process of the pushing mechanism. The supporting mechanism and the pushing mechanism complement each other to ensure the smooth completion of the filter plate replacement process.

[0021] Specifically, the conveying mechanism on the support plate can receive and convey the filter plates ejected from the box away from the outlet, avoiding interference with the sealing plate blocking the outlet. Furthermore, the support mechanism in the replacement mechanism can move with the movement of the third push plate. When the third push plate is ejected, the first push plate is pushed out by the spring and receives the upper filter plate. Simultaneously, the connecting rod pushes the support arms to rotate and insert into the grooves on both sides of the filter plate for support. Through the support of both, the upper filter plates can fall stably and sequentially, avoiding interference with the ejection and retraction process of the third push plate. At the same time, when the third push plate retracts into the mounting slot, it pushes the first push plate back and disengages from supporting the upper filter plate, and the support arms on both sides retract, allowing the upper filter plates to fall smoothly and preparing for the next ejection of the third push plate. This complete replacement process assists in the stable and sequential replacement of the filter plates, making it more efficient and convenient compared to the problems addressed in the background technology.

[0048] An auxiliary solid-liquid separation device for industrial wastewater treatment that facilitates filter plate replacement, the working process of which is as follows:

[0049] First, it should be emphasized that the tank 1 and the process of wastewater entering and leaving the tank 1, as well as the judgment of the timing of filter plate 2 replacement and the transfer of filter plate 2 after replacement, are not within the scope of protection of this solution. The above are applications of existing technology, and those skilled in the art can make appropriate adjustments while meeting the requirements of the solution implementation; the scope of protection of this technical solution is the technical solution for auxiliary replacement of filter plate 2.

[0050] Industrial wastewater enters the tank 1 through the inlet pipe 101, is filtered by the filter plate 2, and is then discharged through the outlet pipe 102.

[0051] When filter plate 2 accumulates a lot of impurities and needs to be replaced, first stop the water inlet, then pull the sealing plate 112 along the limiting frame 113 to open the inlet 105 and outlet 104 by the second electric push rod 111, then push the third push plate 555 along the second through groove 513 by the first electric push rod 554, thereby pushing the filter plate 2 in the carrying box 51 into the box 1 along the through 511 and inlet 105, and continue to push the filter plate 2 in the box 1 to slide out of the box 1 along the support groove 106 and outlet 104. At this time, the new filter plate 2 can be replaced; then drive the sealing plate to close the inlet 105 and outlet 104 by the second electric push rod 111.

[0052] When the push mechanism 55 pushes the filter plate 2 in the replacement mechanism, the support mechanism 53 operates simultaneously. When the third push plate 555 exits the mounting slot 515, the first push plate 531 is pushed out by the spring 5342 and supports the upper filter plate 2 through the support plate 532. At the same time, the connecting arm 536 drives the connecting rod 537 to move and the movement of the adjusting shaft 5371 in the adjusting slot 5381 causes the support arm 538 to rotate and enter the groove 23 of the third through slot 514 to support the filter plate 2. The support arm 538 and the support plate 532 achieve overall support for the upper filter plate 2 and prevent the upper filter plate 2 from falling first when the push mechanism 55 pushes, thus interfering with the retraction and reset of the push mechanism 55.

[0053] When the third push plate 555 retracts into the mounting groove 515, it will also push the support plate 532 back into the mounting groove 515 and the support arm 538 will rotate and exit the groove 23 of the support filter plate 2, so that the upper filter plate 2 will fall naturally to prepare for the next replacement; the filter plate 2 that is pushed out of the box 1 will be conveyed by the conveying mechanism 6 and moved away from the outlet to avoid interference with the sealing plate blocking the outlet.

[0054] Repeat the above steps to continuously replace filter plate 2.

[0055] It should be noted that during the overall auxiliary replacement process, first stop the water intake and open the sealing plate to open the inlet and outlet. Then, the first electric actuator pushes the filter plate to move. Due to the spring, the pushing process is synchronized with the support mechanism. As for the timing of filter plate replacement, it can be set to periodic replacement or determined by observing through the observation window.

[0056] Furthermore, the subsequent collection, processing, and transfer of impurities from the filter plate 2 and its upper surface by the conveying mechanism 6 to the next step of solid-liquid separation industrial wastewater treatment is not the problem to be solved by this invention and is not within the scope of protection of this solution.
