Description

Technical Field

[0001] This utility model relates to the field of electroplating waste liquid filtration technology, and in particular to a waste liquid filtration device for electroplating processing. Background Technology

[0002] Electroplating waste liquid filtration is a very important part of the electroplating industry. Its purpose is to remove solid particles and harmful substances from the waste liquid, reduce environmental pollution, and recover usable metals.

[0003] For example, CN218357896U discloses an electroplating waste liquid filtration device for electroplating processing, which includes a box; two filter barrels are arranged inside the box, and two waste liquid inlet pipes are arranged on the top of the box, with the bottom ends of the two waste liquid inlet pipes connected to the top ends of the two filter barrels through the box.

[0004] However, in the existing technology, during the process of filtering waste liquid, the filtered residue will accumulate at the filter pores of the filter screen. As filtration continues, more and more impurities will accumulate near the filter pores. After long-term use, impurities will clog the filter pores, which will slow down the subsequent filtration speed of waste liquid and thus affect the overall filtration efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that as filtration continues, impurities accumulate near the filter holes, leading to filter blockage after prolonged use. Therefore, this invention proposes a waste liquid filtration device for electroplating.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waste liquid filtration device for electroplating, comprising a collection tank, an inlet pipe fixedly connected to one side of the collection tank, and a filter assembly fixedly connected to the other end of the inlet pipe;

[0007] The filter assembly includes a connecting pipe, a filter plate, and a cleaning plate. One side of the connecting pipe is fixedly connected to one end of the inlet pipe. The filter plate is fixedly installed on the inner wall of the connecting pipe and is located above the inlet pipe. The cleaning plate is slidably connected to the bottom of the connecting pipe and is located at the bottom of the connecting pipe.

[0008] Preferably, a baffle plate is fixedly installed at the bottom of the connecting pipe, and the cleaning plate overlaps the upper surface of the baffle plate.

[0009] Preferably, a vertical rod is fixedly connected to the bottom of the cleaning plate, and the vertical rod passes through the blocking plate.

[0010] Preferably, an electric cylinder is fixedly connected to the bottom of the vertical rod, and the electric cylinder is located below the baffle plate.

[0011] Preferably, a limiting ring is fixedly connected to the outer wall of the connecting pipe, and a support rod is fixedly connected to the bottom of the limiting ring.

[0012] Preferably, a guide frame is fixedly installed on the lower surface of the baffle plate, and the guide frame is located on one side of the vertical rod.

[0013] Preferably, the guide frame and the blocking plate are slidably connected.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, a filter plate is installed by setting a connecting pipe. During filtration, the waste liquid passes through the filter plate and enters the inlet pipe, and finally flows out into the collection tank. During this process, impurities are blocked by the filter plate. After operating for a period of time, the cleaning plate is pushed upward, and the protrusions on the surface of the cleaning plate push away the impurities blocking the filter holes of the filter plate, which plays the role of conveying the filter plate. In this process, the normal flow of waste liquid is not affected, thus avoiding affecting the filtration efficiency.

[0016] 2. In this utility model, a baffle plate is set inside the connecting pipe. The baffle plate is mainly used to seal the connecting pipe so that the waste liquid inside the connecting pipe will not flow out. At the same time, a guide frame is set on the lower surface of the baffle plate to determine the movement path of the vertical rod, so as to ensure that the cleaning plate always moves on the vertical path and prevent misalignment.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a waste liquid filtration device for electroplating, including a collection tank 1, an inlet pipe 2 fixedly connected to one side of the collection tank 1, and a filter assembly 3 fixedly connected to the other end of the inlet pipe 2.

[0025] The filter assembly 3 includes a connecting pipe 31, a filter plate 39, and a cleaning plate 38. One side of the connecting pipe 31 is fixedly connected to one end of the inlet pipe 2. The filter plate 39 is fixedly installed on the inner wall of the connecting pipe 31 and is located above the inlet pipe 2. The cleaning plate 38 is slidably connected to the bottom of the connecting pipe 31 and is located at the bottom of the connecting pipe 31. A baffle plate 35 is fixedly installed at the bottom of the connecting pipe 31 and the cleaning plate 38 overlaps the upper surface of the baffle plate 35.

[0026] The specific settings and functions of this embodiment are described below. The collection tank 1 is used to collect the filtered waste liquid. When in use, the waste liquid first enters the filter assembly 3 and then flows into the collection tank 1 from the inlet pipe 2. During this process, the impurities in the waste liquid will be filtered out by the filter plate 39, and the separated impurities will be concentrated on the upper surface of the filter plate 39. After a long period of filtration, the impurities will block the filter holes of the filter plate 39. At this time, the cleaning plate 38 is used to clear the filter plate 39.

[0027] One end of the connector 31 is connected to an external pipeline for transporting waste liquid. Its bottom is sealed by a baffle plate 35 to ensure that the waste liquid flows into the inlet pipe 2. When using the cleaning plate 38 to clear the filter plate 39, push the cleaning plate 38 upward so that it leaves the baffle plate 35 and contacts the filter plate 39. At this time, the protrusions on the upper surface of the cleaning plate 38 can push away the impurities near the filter holes of the filter plate 39, thereby clearing the filter plate 39 and solving the problem of impurities clogging the filter holes, ensuring the overall filtration efficiency.

[0028] Example 2: Figure 1 , Figure 2 and Figure 3As shown, a vertical rod 37 is fixedly connected to the bottom of the cleaning plate 38. The vertical rod 37 passes through the baffle plate 35. An electric cylinder 34 is fixedly connected to the bottom of the vertical rod 37. The electric cylinder 34 is located below the baffle plate 35. A limit ring 32 is fixedly connected to the outer wall of the connecting pipe 31. A support rod 33 is fixedly connected to the bottom of the limit ring 32. A guide frame 36 is fixedly installed on the lower surface of the baffle plate 35. The guide frame 36 is located on one side of the vertical rod 37. The guide frame 36 is slidably connected to the baffle plate 35.

[0029] The overall effect of this embodiment is that the vertical rod 37 is used to connect the piston rod of the electric cylinder 34. When the piston rod of the electric cylinder 34 extends, it pushes the vertical rod 37. The vertical rod 37 is slidably connected to the guide frame 36. The guide frame 36 can determine the movement path of the vertical rod 37 and prevent the vertical rod 37 from tilting, ensuring that the cleaning plate 38 only moves up and down on the vertical plane.

[0030] The vertical rod 37 passes through the baffle plate 35. During its movement, it will not affect the overall sealing performance. The limiting ring 32 at the bottom of the connecting pipe 31 is connected to the support rod 33. The support rod 33 can support the connecting pipe 31, while the limiting ring 32 can prevent the connecting pipe 31 from tilting.

[0031] The usage and working principle of this device: The connecting pipe 31 is connected to the external pipeline used to transport waste liquid. When in use, the waste liquid will pass through the filter plate 39 in the connecting pipe 31, then flow into the inlet pipe 2, and finally enter the collection tank 1. The bottom of the connecting pipe 31 is sealed by the baffle plate 35 to ensure that the waste liquid flows into the inlet pipe 2.

[0032] After prolonged use, the filter holes of the filter plate 39 will be clogged by the filtered impurities. At this time, the electric cylinder 34 is used to push the vertical rod 37 upward, so that the cleaning plate 38 leaves the blocking plate 35 and contacts the filter plate 39. The protrusions on the upper surface of the cleaning plate 38 can push away the impurities near the filter holes of the filter plate 39, thereby clearing the filter plate 39 and solving the problem of impurities clogging the filter holes.

[0033] The vertical rod 37 is slidably connected to the guide frame 36. The guide frame 36 can determine the movement path of the vertical rod 37 and prevent the vertical rod 37 from tilting. The position of the connecting pipe 31 is restricted by the limiting ring 32 and the support rod 33, which ensures its stability.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
