Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically, it relates to an electrophoretic paint wastewater recycling and treatment device. Background Technology

[0002] As is well known, electrophoresis is one of the most effective methods for coating metal workpieces. Electrophoretic coating is a special coating method in which a conductive workpiece is immersed in a tank filled with a low-concentration electrophoretic coating diluted with water as the anode (or cathode). A corresponding cathode (or anode) is set in the tank. After a direct current is applied between the two electrodes for a period of time, a uniform, fine, and water-insoluble coating film is deposited on the surface of the workpiece.

[0003] A search revealed that CN213085628U discloses an electrophoretic paint wastewater recycling and treatment device. The waste liquid from the rinsing tank flows into the cylindrical filter screen in the first chamber through the drain pipe. The cylindrical filter screen and the circular filter screen filter particulate impurities in the waste liquid. The stirring motor drives the rotating shaft and the stirring plate to stir the waste liquid, causing the waste liquid in the cylindrical filter screen to rotate, accelerating the waste liquid to pass through the cylindrical filter screen and filter metal particles. The filtered wastewater enters the filter to separate the electrophoretic paint and water in the waste liquid.

[0004] The device filters particulate impurities in waste liquid through a cylindrical filter screen and a circular filter screen. However, the filtered particulate impurities will accumulate on the inner walls of the two filter screens, which makes it cumbersome and difficult to clean the accumulated particulate impurities in the future. This causes inconvenience to the cleaning work and reduces the cleaning efficiency.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To address the technical problem that the device filters particulate impurities from waste liquid using cylindrical and circular filter screens, but the filtered particulate impurities accumulate on the inner walls of the two screens, making subsequent cleaning of the accumulated impurities cumbersome and difficult, thus causing inconvenience and reducing cleaning efficiency, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An electrophoretic paint wastewater recycling and treatment device includes a stirring drum and a filter cylinder installed below the stirring drum. The stirring drum and the filter cylinder are equipped with a filtration cleaning mechanism and a rotation positioning mechanism.

[0008] The filtration and cleaning mechanism includes a dual-shaft motor mounted above the mixing drum. A filter plate is rotatably mounted inside the filter drum, and a force-bearing plate is mounted on the filter plate. The filter plate is used to filter wastewater, and the force-bearing plate is used to generate vibration under force, thereby driving the filter plate to vibrate and thus complete the cleaning.

[0009] The rotation positioning mechanism includes a positioning hole on the outer wall of the filter cylinder, and a rotating plate is connected to one side of the filter plate. The positioning hole is used to position the filter plate, and the rotating plate is used to rotate the filter plate.

[0010] In a preferred embodiment of this utility model, the filtration and cleaning mechanism includes a support frame connected to the top of the stirring drum, a dual-shaft motor mounted on the top of the inner wall of the support frame, a rotating rod connected to the bottom output end of the dual-shaft motor, a stirring blade connected to the outer wall of the rotating rod, a squeezing rod connected to the top output end of the dual-shaft motor, a rotating hole opened in the inner wall of the filter drum, a rotating shaft rotatably mounted on the inner wall of the rotating hole, and the end of the rotating shaft away from the inner wall of the rotating hole connected to the outer wall of one side of the filter plate.

[0011] In a preferred embodiment of this utility model, the rotation positioning mechanism includes a rotating shaft connected to the outer wall of the filter plate. The end of the rotating shaft away from the filter plate is connected to the outer wall of one side of the rotating plate. A sliding hole is provided on the outer wall of one side of the rotating plate. A second spring is connected to the inner wall of the sliding hole. A positioning rod is connected to the end of the second spring away from the inner wall of the sliding hole. A pull rod is connected to the outer wall of the end of the positioning rod away from the positioning hole.

[0012] In a preferred embodiment of this utility model, a fixed frame is connected to the outer wall of the filter cylinder, a first spring is connected to the inner wall of the fixed frame, a striking rod is connected to the end of the first spring away from the inner wall of the fixed frame, a connecting rod is connected to the outer wall of the striking rod, a force-bearing block is connected to the end of the connecting rod away from the striking rod, and a force-bearing inclined surface is opened on one side of the outer wall of the force-bearing block.

[0013] In a preferred embodiment of this utility model, an extrusion slope is provided on the outer wall of the end of the extrusion rod away from the dual-axis motor, and the extrusion slope is in close contact with the force-bearing slope provided on the force-bearing block.

[0014] In a preferred embodiment of this utility model, there are two positioning holes, which are distributed symmetrically on the outer wall of the filter cylinder.

[0015] In a preferred embodiment of this utility model, the outer wall of the positioning rod is fitted to the inner wall of the positioning hole, and the outer wall of the positioning rod is fitted to the inner wall of the sliding hole opened on the outer wall of the rotating plate.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention utilizes a dual-axis motor to drive a pressing rod to rotate, thereby moving a force-bearing rod and causing a striking rod to move to the right. Simultaneously, this compresses a first spring. As the force-bearing rod continues to rotate and no longer contacts the striking rod, the first spring rebounds and resets, pushing the striking rod back to its original position. This allows the striking rod to strike the force-bearing plate, causing the filter plate to vibrate. This vibration of the force-bearing plate then vibrates the filter plate, dislodging impurities and metal particles adhering to it. This completes the cleaning of the filter plate without requiring tedious manual operation, thus improving cleaning efficiency.

[0018] This invention releases the filter plate from its positioning by pulling a lever to disengage the outer wall of the positioning rod from the inner wall of the upper positioning hole. Then, rotating the rotating plate causes the filter plate to rotate 180 degrees, simultaneously moving the positioning rod to the lower positioning hole. Releasing the lever allows the second spring to return the positioning rod, repositioning it into the inner wall of the lower positioning hole, thus completing the filter plate's positioning. This facilitates the rotation of the filter plate while simultaneously providing positioning, preventing rotation from affecting filtration during subsequent processes.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 4 As shown, an electrophoretic paint wastewater recycling and treatment device includes a stirring drum 1 and a filter drum 2 installed below the stirring drum 1. A filtration cleaning mechanism 31 and a rotation positioning mechanism 32 are installed in the stirring drum 1 and the filter drum 2. The filtration cleaning mechanism 31 includes a dual-shaft motor 312 installed above the stirring drum 1. A filter plate 317 is rotatably installed inside the filter drum 2. A force-bearing plate 318 is installed on the filter plate 317. The filter plate 317 is used to filter wastewater, and the force-bearing plate 318 is used to generate vibration under force, thereby driving the filter plate 317 to vibrate to complete the cleaning. The rotation positioning mechanism 32 includes a positioning hole 321 opened on the outer wall of the filter drum 2. A rotating plate 323 is connected to one side of the filter plate 317. The positioning hole 321 is used to position the filter plate 317, and the rotating plate 323 is used to rotate the filter plate 317.

[0028] Furthermore, the filtration and cleaning mechanism 31 includes a support frame 311 connected to the top of the stirring cylinder 1, a dual-shaft motor 312 mounted on the top of the inner wall of the support frame 311, a rotating rod 313 connected to the bottom output end of the dual-shaft motor 312, a stirring blade 314 connected to the outer wall of the rotating rod 313, a pressing rod 315 connected to the top output end of the dual-shaft motor 312, a rotating hole opened in the inner wall of the filter cylinder 2, a rotating shaft 316 rotatably mounted on the inner wall of the rotating hole, and the end of the rotating shaft 316 away from the inner wall of the rotating hole connected to the outer wall of one side of the filter plate 317.

[0029] Furthermore, a fixing frame 319 is connected to the outer wall of the filter cartridge 2, and a first spring 3110 is connected to the inner wall of the fixing frame 319. A striking rod 3111 is connected to the end of the first spring 3110 away from the inner wall of the fixing frame 319. A connecting rod 3112 is connected to the outer wall of the striking rod 3111, and a force-bearing block 3113 is connected to the end of the connecting rod 3112 away from the striking rod 3111. A force-bearing inclined surface is opened on one side of the outer wall of the force-bearing block 3113.

[0030] Furthermore, the outer wall of the end of the extrusion rod 315 away from the dual-axis motor 312 has an extrusion slope, which is in close contact with the force-receiving slope on the force-receiving block 3113. This allows the two to better apply and receive force, thereby driving the striking rod 3111 to move.

[0031] The rotation positioning mechanism 32 includes a rotating shaft 322 connected to the outer wall of the filter plate 317. The end of the rotating shaft 322 away from the filter plate 317 is connected to the outer wall of one side of the rotating plate 323. A sliding hole is provided on the outer wall of one side of the rotating plate 323. A second spring 324 is connected to the inner wall of the sliding hole. A positioning rod 325 is connected to the end of the second spring 324 away from the inner wall of the sliding hole. A pull rod 326 is connected to the outer wall of the end of the positioning rod 325 away from the positioning hole 321.

[0032] Furthermore, there are two positioning holes 321, which are distributed symmetrically on the outer wall of the filter cylinder 2. This allows the filter plate 317 to still be positioned after being flipped over, ensuring the stability of the filter plate 317.

[0033] Furthermore, the outer wall of the positioning rod 325 is fitted to the inner wall of the positioning hole 321, and the outer wall of the positioning rod 325 is fitted to the inner wall of the sliding hole opened on the outer wall of the rotating plate 323. By matching the positioning rod 325 with the positioning hole 321, the stability of the two after being engaged and connected can be guaranteed, thereby ensuring the filtration stability of the filter plate 317.

[0034] The implementation principle of the electrophoretic paint wastewater recycling and treatment device in this embodiment is as follows: First, wastewater and reagents are added into the mixing drum 1 through the opening at the top. Then, the dual-shaft motor 312 is turned on, and its bottom output end will drive the rotating rod 313 to rotate. As the rotating rod 313 rotates, it drives the stirring blade 314 to rotate, thereby fully mixing the wastewater and reagents. After mixing, the valve at the bottom of the mixing drum 1 is opened, allowing the wastewater to flow into the filter drum 2. Then, the filter plate 317 filters the impurities and metal particles in the wastewater. The filtered impurities and metal particles will accumulate on the filter plate 317. When it is necessary to process the impurities and metal particles, the filter plate 317 can be flipped, rotating 180 degrees. The impurities and metal particles accumulated on it will fall downwards due to gravity, thereby completing the initial cleaning. Then, the wastewater is further processed. The rotation of the top output end of the dual-axis motor 312 drives the extrusion rod 315 to rotate, causing the extrusion rod 315 to contact and extrude force block 3113. This causes force block 3113 to move connecting rod 3112 away from filter cylinder 2, thereby moving the striking rod 3111 below. During this movement, the first spring 3110 is also extruded. As force block 3113 continues to rotate and no longer contacts force block 3113, the first spring 3110 rebounds, causing the striking rod 3111 to reset and then contact and strike force plate 318, thereby causing filter plate 317 to vibrate. This knocks off impurities and metal particles adhering to filter plate 317, thus completing the cleaning of filter plate 317 without the need for tedious operation by staff, improving cleaning efficiency.

[0035] When the filter plate 317 needs to be rotated, first pull the lever 326, causing the lever 326 to rotate the positioning rod 325 to the right. At the same time, during the movement of the positioning rod 325, the second spring 324 is squeezed. At this time, the outer wall of the positioning rod 325 will disengage from the outer wall of the filter cylinder 2 and be located in the inner wall of the upper positioning hole 321. Then rotate the rotating plate 323, causing the rotating shaft 322 and the filter plate 317 to rotate. After rotating 180 degrees, the positioning rod 325 rotates to the position of the lower positioning hole 321. Then release the lever 326, and the second spring 324 will rebound to reset the positioning rod 325, so that it is inserted into the inner wall of the lower positioning hole 321, thus completing the positioning of the filter plate 317. This facilitates the rotation of the filter plate 317 and also positions the filter plate 317 to prevent rotation from affecting the filtration process in the subsequent filtration process.
