Description

Technical Field

[0001] This utility model belongs to the field of electrical and electronic product processing technology, and in particular relates to a purification device for continuous use of chemical treatment liquids for electrical and electronic products. Background Technology

[0002] Currently, chemical treatment solutions are commonly used in the production process of electrical and electronic products to protect their paint surfaces. These solutions utilize the hydrolysis products of the treatment agents to react on the metal surface and generate a chemically stable nanocomposite conversion film. This forms a composite conversion layer that connects organic and inorganic components, improving the adhesion and corrosion resistance of the paint coating on the surface of electrical and electronic products and increasing their service life.

[0003] During the use of chemical treatment solutions, continuous circulation is required. If the surface of the product is not cleaned thoroughly or if there is a chemical reaction between the treatment solution and the product, suspended contaminants will be generated. These suspended contaminants will adhere to the surface of the workpiece during the production of electrical appliances, which will seriously affect the product quality. After standing, the suspended contaminants will settle due to their weight, requiring the chemical treatment solution to be transferred to another tank, which will prolong the production cycle and is not conducive to use.

[0004] To address these issues, we provide a purification device for the continuous use of chemical treatment solutions in electrical and electronic products. Utility Model Content

A positioning plate 54 is fixedly connected to the left side of the front and rear sides of the fixing frame 52. A drain shell 55 is connected to the right side of the bottom of the housing 1.

[0028] Specifically: the filter screen 2 can filter suspended solids in the treatment liquid, the cleaning mechanism 3 can collect the cleaned dirt, the water supply chamber 41 can transport the treatment liquid back into the housing 1 through the delivery pipe 43, the pulse jet mechanism 42 can generate pulse jets to backwash and clean the filter screen 2, spraying out the dirt blocking the filter holes, so that the filter screen 2 can continuously perform filtration, and the electric cylinder 51 is used to control the movement of the fixed frame 52 and the scraper 53. The electric cylinder 51 controls the scraper 53 to slowly reset, and the scraper 53 transports the settled dirt into the drain shell 55 for easy discharge.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the cleaning mechanism 3 includes two electric actuators 31, each with one side fixedly connected to the housing 1. A collection shell 32 is provided on the top of the housing 1. The top of the output end of the electric actuators 31 is fixedly connected to the collection shell 32. A drain pipe is connected to the top of the collection shell 32, and the bottom of the collection shell 32 extends into the inner cavity of the housing 1. The pulse jet mechanism 42 includes a mounting frame 421, the rear side of which is fixedly connected to the water supply chamber 41. A cylinder 422 is fixedly connected to the top of the mounting frame 421. A pressure block is fixedly connected to the top of the output end of the cylinder 422 through the mounting frame 421. A water spray pipe 423 is connected to the front side of the water supply chamber 41. A piston 424 is provided in the inner cavity of the water spray pipe 423. The front side of the piston 424... A push rod 425 is fixedly connected, and a tension spring 426 is sleeved on the surface of the push rod 425. The front side of the push rod 425 passes through the water spray pipe 423 and is fixedly connected to a trapezoidal block 427. A positioning sleeve is fixedly connected to the bottom of the water spray pipe 423. A positioning rod is slidably connected to the inner cavity of the positioning sleeve. The right side of the positioning rod is fixedly connected to the trapezoidal block 427. The front and rear sides of the right side of the sewage discharge shell 55 are connected to sewage pipes. A control valve is installed on the surface of the sewage pipe. An inclined slope is provided on the left side of the top of the sewage discharge shell 55. A liquid pump connector is connected to the left side of the front and rear sides of the shell 1. An overflow pipe is connected to the right side of the front side of the shell 1. A treatment liquid injection pipe is connected to the top of the shell 1. Support columns are fixedly connected to the front and rear sides of the bottom of the shell 1. Anti-slip plates are fixedly connected to the bottom of the support columns.

[0031] Specifically: the electric push rod 31 controls the height of the collection shell 32, allowing it to sink into the interior of the housing 1. The collection shell 32 collects the dirt removed by backflushing. The mounting bracket 421 facilitates the installation and fixation of the cylinder 422. The cylinder 422 controls the height of the pressure block, which compresses the trapezoidal block 427 during movement. The water spray pipe 423 works with the piston 424 to circulate the treatment liquid in the water delivery chamber 41, rapidly spraying the treatment liquid into the interior of the housing 1. The tension spring 426 allows the piston 424 to return to its original position when no longer compressed. The push rod 425 works with the trapezoidal block 427 to control the piston 427. The positioning sleeve and positioning rod of the 4-position device can limit the trapezoidal block 427, enabling it to move back and forth smoothly and improving its stability during movement. The drain pipe is used to discharge the precipitated dirt into the drain shell 55. The control valve is used to control the opening and closing of the drain pipe. The inclined slope facilitates the transport of sediment into the drain shell 55. The liquid pump connector facilitates the connection between the liquid pump and the shell 1. The overflow pipe can discharge the dirt floating on the surface of the treatment liquid inside the shell 1. The treatment liquid injection pipe can circulate the treatment liquid. The support column and anti-slip plate can provide stable support for the shell 1 and prevent it from shifting during operation.

[0032] The working principle of this utility model is as follows: After the chemical treatment liquid is injected into the inner cavity of the housing 1 through the treatment liquid injection pipe, the external liquid pump connected to the liquid pump connector continuously circulates and transports the treatment liquid. When the treatment liquid flows through the filter screen 2, suspended pollutants are intercepted by the filter screen 2, realizing the filtration operation of the treatment liquid. When the pores of the filter screen 2 are gradually blocked by dirt, the cylinder 422 drives the pressure block to press down, so that the pressure block contacts the trapezoidal block 427 and pushes the push rod 425 to move backward. The piston 424 compresses the treatment liquid in the water delivery chamber 41 to form a high-pressure jet, which continuously pulses backwashes the surface of the filter screen 2 through one of the delivery pipes 43, peeling off the dirt attached to the surface of the filter screen 2 and spraying out the dirt blocking the pores of the filter screen 2. When the machine is stopped and standing, it can be cleaned by the sediment scraping component 5. When cleaning is required without stopping the machine, the electric push rod 31 can be activated to use electricity. Push rod 31 controls the collection shell 32 to move downwards into the housing 1. The collection shell 32 blocks one side of the filter screen 2, and the impurities generated by backflushing enter the collection shell 32 for storage. When the electric push rod 31 is reset, the collection shell 32 can be moved upwards, making it easier for staff to clean it. The cleanliness of the treatment liquid can be maintained without stopping the machine to rotate the tank. This reduces the risk of suspended matter adhering to the surface of the workpiece and shortens the production cycle caused by equipment maintenance. When cleaning the sediment, the suspended matter in the treatment liquid settles and the sediment accumulates at the bottom of the housing 1. The electric cylinder 51 periodically drives the fixed frame 52 to move the scraper 53 laterally. The scraper 53 pushes the sediment along the bottom of the housing 1 into the drain shell 55. The inclined slope guides the sediment to gather in the drain shell 55, and centralized discharge is achieved by opening the control valve.
