Description

Technical Field

[0001] This utility model relates to the field of coating wastewater treatment technology, and more specifically, to a paint sludge dewatering system for a coating wastewater recycling treatment machine. Background Technology

[0002] The painting process generates a large amount of wastewater containing paint residue. The presence of paint residue not only affects the subsequent treatment of wastewater, but also causes serious environmental pollution if discharged indiscriminately. Therefore, the paint residue needs to be dehydrated before discharging the wastewater.

[0003] Currently, painting wastewater generally needs to be filtered before treatment to collect floating paint residue. Because the collected paint residue has a high water content, it easily adheres to the bottom of the filter box. Its fragmented nature makes cleaning it from the filter box cumbersome, leading to incomplete cleaning, clogging of the filter pores, and wasting time and effort. Therefore, a structure that can directly dehydrate the paint residue within the filter box is needed. Based on this, we propose a paint residue dehydration system for a painting wastewater recycling treatment machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a paint sludge dewatering system for a coating wastewater recycling treatment machine. This system solves the technical problem that the current filtered paint sludge has a lot of moisture, easily adheres to the surface of the filter plate in the filter box, is difficult to clean, and causes time-consuming and labor-intensive cleaning work.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a paint sludge dewatering system for a coating wastewater recycling treatment machine, including a filter barrel body, wherein a pressing component that fits against the ground can be inserted into the bottom of the filter barrel body;

[0006] The filter barrel body includes a barrel body and a base. A filter plate with filter holes is fixedly installed between the bottom inner walls of the base. A pressing component that can move up and down inside the barrel body is fixedly installed on the top of the barrel body. Several support legs are arranged in an array on the outer wall of the base. A lifting component that is fixedly connected to the outer wall of the barrel body is fixedly installed on the top of each of the support legs.

[0007] The extrusion component includes a base plate, on the top of which a first hydraulic cylinder is fixedly mounted. A tray is fixedly mounted on the output end of the first hydraulic cylinder. The top of the tray has a ring array of several insert rods corresponding to the positions of the filter holes in the filter plate.

[0008] This invention uses a combination of a plug and a filter plate to seal the filter holes, improving the flatness of the filter plate surface. Simultaneously, it pushes out paint residue from the filter holes, keeping them clear. Then, under the action of the pressing component, it works in conjunction with the filter plate to squeeze the paint residue, causing the adsorbed water to be squeezed out, forming a paint residue cake. This reduces the adhesion strength of the paint residue. The separate design of the barrel and base facilitates direct ejection of the paint residue cake, increasing the processing speed and reducing the processing difficulty.

[0009] Preferably, the bottom of the filter plate is provided with an upwardly inclined connecting groove, and the top of the tray is provided with a guide surface that fits into the connecting groove.

[0010] Preferably, an annular box for collecting water is fixedly provided at the bottom outer edge of the tray, and the diameter of the annular box is larger than the diameter of the filter barrel body.

[0011] Preferably, the outer edge of the annular box is fixedly provided with a positioning tube corresponding to the position of the support leg, and the bottom of the support leg is fixedly provided with a positioning rod that is inserted and connected to the positioning tube.

[0012] Preferably, the pressing component includes two second hydraulic cylinders, which are symmetrically arranged around the top center of the barrel, and a pressure plate that fits against the inner wall of the barrel is installed between the output ends of the two second hydraulic cylinders.

[0013] Preferably, a cross-shaped dividing plate is fixedly provided at the bottom of the pressure plate, and the bottom of the dividing plate is integrally formed with several serrations.

[0014] Preferably, a drainage groove is provided on the side wall where the barrel body fits against the base, and the outlet diameter of the drainage groove is smaller than the diameter of the filter holes of the filter plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This utility model can seal the filter holes by combining the insert rod with the filter plate, thereby improving the flatness of the filter plate surface. At the same time, it can push out the paint residue in the filter holes, keeping the filter holes unobstructed. Then, under the action of the pressing component, it can work with the filter plate to squeeze the paint residue, so that the paint residue can squeeze out the adsorbed water during the pressure process, thereby achieving the effect of forming a paint residue cake, thereby reducing the adhesion strength of the paint residue. The design of separating the barrel and the base facilitates the direct ejection of the paint residue cake, which can improve the processing speed of the paint residue cake and reduce the processing difficulty.

[0017] 2. This utility model also features a design where the length of the insert rod is greater than the depth of the filter plate holes, allowing the paint cake to be ejected under the operation of the first hydraulic cylinder. This facilitates the separation of the paint cake from the surface of the filter plate. The dividing plate structure at the bottom of the pressing component can divide the paint sludge during the pressing process. The serrated design improves the dividing effect, making it easy to remove the paint cake in stages after ejection. This eliminates the obstruction of the base and further improves the convenience of paint sludge cleaning. Attached Figure Description

[0025] The filter barrel body 1 includes a barrel body 101 and a base 102. A filter plate 103 with filter holes is fixedly installed between the bottom inner walls of the base 102. A pressing member 3 that can move up and down inside the barrel body 101 is fixedly installed on the top of the barrel body 101. Several support legs 104 are arranged in an array on the outer wall of the base 102. A lifting member 105 that is fixedly connected to the outer wall of the barrel body 101 is fixedly installed on the top of each of the support legs 104. The base 102 can maintain a fixed position under the support of the support legs 104. The barrel body 101 can be raised and lowered to adjust its height under the connection of the lifting member 105, so as to facilitate its combination or separation with the base 102. The pressing member 3 can move up and down inside the barrel body 101 to achieve the action of squeezing the paint residue.

[0026] The extrusion component 2 includes a base plate 201. A first hydraulic cylinder 202 is fixedly installed on the top of the base plate 201. A tray 203 is fixedly installed on the output end of the first hydraulic cylinder 202. The top of the tray 203 has a ring array of several insertion rods 204 corresponding to the positions of the filter holes of the filter plate 103. The height of the tray 203 can be adjusted by the first hydraulic cylinder 202, so that the top of the insertion rods 204 can move within the filter holes of the filter plate 103 to achieve the effect of blocking the filter holes, and at the same time, it can also clear the filter holes.

[0027] In an embodiment of this utility model, the bottom of the filter plate 103 is provided with an upwardly inclined connecting groove 106, and the top of the tray 203 is provided with a guide surface 205 that fits into the connecting groove 106; the water filtered by the filter plate 103 can be guided by the guide surface 205, and the cooperation between the connecting groove 106 and the guide surface 205 can increase the upward movement distance of the guide surface 205.

[0028] In an embodiment of this utility model, an annular box 206 for collecting water is fixedly provided at the bottom outer edge of the tray 203, and the diameter of the annular box 206 is larger than the diameter of the filter barrel body 1; the annular box 206 can be used to centrally discharge the filtered wastewater, reducing the probability of leakage.

[0029] In an embodiment of this utility model, a positioning tube 207 corresponding to the position of the support leg 104 is fixedly provided on the outer side of the annular box 206, and a positioning rod 108 connected to the positioning tube 207 is fixedly provided at the bottom of the support leg 104; the combination of the positioning tube 207 and the positioning rod 108 can position the combination of the filter barrel body 1 and the extrusion member 2, so that the insertion rod 204 and the filter hole of the filter plate 103 are aligned.

[0030] In an embodiment of this utility model, the pressing component 3 includes two second hydraulic cylinders 301, which are symmetrically arranged around the top center of the barrel 101. A pressure plate 302 that fits against the inner wall of the barrel 101 is installed between the output ends of the two second hydraulic cylinders 301. A cross-shaped dividing plate 4 is fixedly provided at the bottom of the pressure plate 302. Several serrations 401 are integrally formed at the bottom of the dividing plate 4. The dividing plate 4 at the bottom of the pressure plate 302 can divide the paint residue into cakes when it is squeezed. The serrations 401 can improve the effect and make it easier to remove the paint residue cakes in pieces.

[0031] In an embodiment of this utility model, a drainage groove 107 is provided on the side wall where the barrel 101 and the base 102 are attached. The outlet diameter of the drainage groove 107 is smaller than the diameter of the filter holes of the filter plate 103. By setting the drainage groove 107, the wastewater squeezed out when the paint residue is squeezed into a cake can be discharged, thereby improving the dehydration effect of the paint residue cake.

[0032] Working Principle: This embodiment provides a paint sludge dewatering system for a coating wastewater recycling treatment machine. During use, coating wastewater can be poured into the interior of the tank 101 through the water inlet on the outer wall of the tank 101. When the wastewater comes into contact with the filter plate 103, it automatically flows down along the filter holes, allowing the mixed paint sludge to remain on the surface of the filter plate 103, achieving a separation effect. When the paint sludge on the surface of the filter plate 103 accumulates to a certain thickness, the addition of wastewater can be stopped. Then, the extruder 2 and the pressing component 3 can be activated simultaneously. First, the extruder 2 moves upward, causing the top insert rod 204 to be inserted into the filter holes of the filter plate 103. The top of the insert rod 204 is then moved to a position flush with the surface of the filter plate 103, ensuring the filter plate 103 is in a complete state. During the upward movement of the insert rod 204, the filter holes are dewatered. The paint residue adhering to the inner wall is pushed out, which can maintain the smooth filtration of the filter holes. Then, under the operation of the pressing component 3, the pressure plate 302 can be controlled to move down to squeeze the accumulated paint residue. The wastewater generated by the squeezing can flow out along the drainage groove 107 opened on the side of the barrel 101, thereby reducing the water absorbed by the paint residue and achieving the dehydration effect. After the paint residue is squeezed into a cake, the barrel 101 can be lifted by the operation of the lifting component 105 to separate it from the base 102, thereby exposing the paint residue cake. Then, under the continuous operation of the squeezing component 2, the paint residue cake can be lifted up, so that the outer edge of the paint residue cake separates from the inner wall of the base 102, making it easy to remove the paint residue cake. In this way, the difficulty of cleaning paint residue can be effectively reduced, the convenience of cleaning can be improved, the cleaning speed can be accelerated, and the time and labor saving effect can be achieved.

As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
