Description

Technical Field

[0001] This utility model relates to the field of electrophoretic coating technology, and in particular to an electrophoretic coating recycling and reuse device. Background Technology

[0002] Electrophoretic coating, as an advanced surface treatment technology, is widely used in many industries such as automotive, machinery manufacturing, and electronics. This technology uses an electric field to uniformly deposit coating particles onto the workpiece surface, effectively improving the workpiece's corrosion resistance and decorative properties. During the electrophoretic coating process, the recycling of the coating and wastewater treatment are crucial.

[0003] Existing patents, such as Chinese Patent Publication No. CN215049166U, disclose a device for filtering and reusing electrophoretic coating waste liquid. This device includes a tank with a partition inside. A seepage tank is located on one side of the tank, and an electrophoresis tank is located on the other side. A motor is mounted at the bottom of the tank via a motor mount. A reducer is connected to the output shaft of the motor, and a first bevel gear is located at the output shaft of the reducer. An inlet pipe is located at the bottom of the tank, and a pump is installed at the bottom of the inlet pipe. An outlet pipe is connected to the outlet of the pump, and a filter tank is located on the outlet pipe. A filter screen is installed inside the filter tank, and a delivery pipe is located on the side wall of the filter tank above the filter screen. Two discs are connected to the top of the delivery pipe. This device effectively concentrates, filters, and reuses electrophoretic coating waste liquid, avoiding direct discharge. It not only reduces environmental pollution but also improves raw material utilization, reduces resource waste, and lowers operating costs.

[0004] While the aforementioned patented technology enables the electrophoretic coating waste liquid filtration and reuse device to effectively concentrate, filter, and reuse the waste liquid, avoiding direct discharge, it not only reduces environmental pollution but also improves raw material utilization, reduces resource waste, and lowers operating costs. However, the structural design of this patented technology requires disassembling numerous components such as the top cover and related connecting pipes when cleaning these filter components, making the operation cumbersome and time-consuming. This not only increases the labor costs of equipment maintenance but also affects production efficiency due to prolonged equipment downtime. Furthermore, most of the filtered impurities accumulate below the filter screen, and due to the limitations of the device's structure, there is a lack of convenient impurity discharge channels or cleaning auxiliary structures, making impurity removal difficult. Residual impurities not only reduce filtration efficiency but also, with long-term accumulation, can lead to filter screen blockage, affecting the normal operation of the entire recycling and reuse device and increasing the risk of equipment failure. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of inconvenience in replacing the filter screen and cleaning the impurities after filtration in the above-mentioned patented technology, and to propose an electrophoretic coating recycling and reuse device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electrophoretic coating recycling and reuse device, comprising a filter box, wherein two first square holes are symmetrically opened on the top of the filter box, and a first ring plate is fixedly connected inside each of the first square holes.

A trapezoidal funnel is fixedly connected to the bottom of the filter box at the first square hole, and a discharge pipe is fixedly connected to the bottom of the trapezoidal funnel near the center. An inlet chamber and an outlet chamber are respectively opened inside the filter box near both ends. A second square hole is opened on the top of the filter box between the inlet chamber and the first square hole. A connecting pipe is symmetrically fixed inside the second square hole near the bottom, and both ends of the connecting pipe are connected to the inlet chamber and the first square hole respectively. A round hole is opened between the first square hole and the outlet chamber near the top.

[0007] Preferably, a first sealing ring gasket is fixedly connected to the bottom of each L-shaped ring plate, and the bottom of the first sealing ring gasket is in close contact with the bottom inner wall of the first ring groove.

[0008] Preferably, the top of the filter box and the edge of the first square hole are provided with a second annular groove, and a cover plate is embedded in the interior of the second annular groove. The surface of the cover plate and near the four corners are provided with mounting holes.

[0009] Preferably, a handle is fixedly connected to the top of the cover plate and near the center.

[0010] Preferably, a second sealing ring gasket is provided between the cover plate and the second annular groove.

[0017] 1. In this utility model, by removing the bolts on the cover plate, the filter screen inside one of the first square holes can be taken out, which facilitates the disassembly and cleaning of the filter screen. At the same time, during the disassembly and cleaning process, the other first square hole can still filter electrophoretic coating waste liquid, which can prevent the equipment from stopping due to the cleaning and disassembly process, thereby ensuring production efficiency and enabling enterprises to carry out production operations more efficiently.

[0018] 2. In this utility model, the combination of trapezoidal funnel and impurity discharge pipe can guide impurities to be discharged smoothly, avoiding the accumulation of impurities under the filter screen. This can prevent residual impurities from reducing filtration efficiency and clogging the filter screen, thereby ensuring the long-term stable operation of the filter components, reducing the risk of equipment failure, and improving the reliability and service life of the entire recycling device.
