[0037] During the operation of the coating supply system, in order to effectively clean the pipelines and eliminate slurry blockage and pipe bursting problems, such as... Figures 1-4 As shown, this utility model provides a coating material feeding system. The coating material feeding system includes a material box 1, a stirring device 2, a sewage discharge component 3, a first filter 4, a cleaning water inlet component 5, and a pump 6.

[0038] The material box 1 is used to store slurry. The stirring device 2 is connected to the material box 1 via the discharge pipe 11. The sewage discharge component 3 is installed on the discharge pipe 11 and can be connected to or disconnected from the discharge pipe 11. The first filter 4 is connected to the discharge port of the stirring device 2 via the first connecting pipe 21. The cleaning water inlet component 5 is installed on the first connecting pipe 21 and can be connected to or disconnected from the first connecting pipe 21. The inlet of the pump 6 is connected to the first filter 4, and the outlet of the pump 6 is connected to the inlet of the material box 1.

[0039] When the coating supply system is working normally, the drain assembly 3 is disconnected from the discharge pipe 11, and the cleaning water inlet assembly 5 is disconnected from the first connecting pipe 21. At this time, the slurry enters the mixing device 2 for mixing, is filtered by the first filter 4, and is pumped into the material box 1 by the pump 6, thus supplying the slurry. When the pipeline needs to be cleaned, the drain assembly 3 is connected to the discharge pipe 11, and the cleaning water inlet assembly 5 is connected to the first connecting pipe 21. External cleaning water enters the first connecting pipe 21 through the cleaning water inlet assembly 5, and flows through the first filter 4, the material box 1, and the discharge pipe 11 under the action of the pump 6 before being discharged from the drain assembly 3. Through the above method, the pipeline can be effectively cleaned, thereby eliminating slurry blockage and preventing pipe bursts.

[0040] In some embodiments, the first filter 4 is a basket filter, preferably with a 20-mesh filter element. Basket filters are easy to replace and clean, thereby ensuring effective filtration of slurry while facilitating maintenance and reducing the difficulty of maintenance.

[0041] In some embodiments, the drain assembly 3 includes a first three-way control valve 31 and a drain pipe 32. The first port of the first three-way control valve 31 is connected to the material box 1, the second port of the first three-way control valve 31 is connected to the stirring device 2, and the drain pipe 32 is connected to the third port of the first three-way control valve 31. The first three-way control valve 31 can selectively control the connection between its first port and its second port or its third port. In this embodiment, the first three-way control valve 31 can be pneumatically controlled. By using the first three-way control valve 31, when the coating supply system is working normally, the first port of the first three-way control valve 31 is connected to its second port, thereby allowing excess coating slurry to flow back to the stirring device 2. When it is necessary to clean the pipeline of the coating supply system, by controlling the first three-way control valve 31 to connect its first port to its third port, the wastewater after cleaning the pipeline can flow out through the drain pipe 32.

[0042] In some embodiments, the cleaning water inlet assembly 5 includes a second three-way control valve 51 and an inlet pipe 52. The first port of the second three-way control valve 51 is connected to the stirring device 2, the second port of the second three-way control valve 51 is connected to the first filter 4, and the inlet pipe 52 is connected to the third port of the second three-way control valve 51. The second three-way control valve 51 can selectively control the connection between the first port and the second port or the third port. When the coating supply system is working normally, the first port of the second three-way control valve 51 is connected to the second port, so that the stirred slurry can be filtered through the first filter 4 and then flow into the material box 1 under the action of the pump 6. When it is necessary to clean the pipeline of the coating supply system, the first port of the second three-way control valve 51 is connected to the third port by controlling the second three-way control valve 51. Water for cleaning the pipeline enters through the inlet pipe 52, cleans the first connecting pipeline 21, the first filter 4, the material box 1, and the discharge pipeline 11, and then flows out through the drain pipe 32.

[0043] In some embodiments, a second filter 7 is provided on the second connecting pipe 12 between the pump 6 and the material box 1. The second filter 7 is an ultrasonic filter. By providing the second filter 7, the slurry flowing in through the pump 6 can be further filtered. The ultrasonic waves break up the slurry lumps that were not screened out in the first filter, thereby preventing the second filter 7 from becoming clogged and causing the pipe to burst. Moreover, it can ensure that the slurry supplied to the material box 1 is more uniform and free of lumps, thus ensuring the subsequent coating effect.

[0044] In some embodiments, the second filter 7 includes a cylindrical body 71 and, from the inside out, an ultrasonic filter rod 72, a filter cartridge 73, a filter screen 77, and a supporting cylindrical grid 75. The supporting cylindrical grid 75 is disposed within the cylindrical body 71. The filter cartridge 73 is connected to the pump 6, and the cylindrical body 71 is connected to the material box 1. After the slurry delivered by the pump 6 enters the space between the ultrasonic filter rod 72 and the filter cartridge 73, the ultrasonic waves emitted by the ultrasonic filter rod 72 break up small slurry particles. The slurry then passes through the filter cartridge 73 and the filter screen 77, enters the space between the supporting cylindrical grid 75 and the cylindrical body 71, and then enters the material box 1 through the second connecting pipe 12. Simultaneously, the supporting cylindrical grid 75 effectively supports the filter screen 77, preventing it from rupturing due to excessive pressure during filtration, thereby extending the service life of the filter screen 77.

[0045] In some embodiments, the second filter 7 further includes a cover 74, which covers one end of the cylinder 71 and is detachably connected to the filter cylinder 73. One end of the filter screen 77 is inserted into the cover 74. Specifically, in this embodiment, the cover 74 and the filter cylinder 73 are connected by threads, which facilitates installation and disassembly and ensures the strength of the connection between the cover 74 and the filter cylinder 73. In other embodiments, the filter cylinder 73 and the cover 74 can also be designed as a snap-fit ​​connection, with a buckle on one of the filter cylinder 73 and a slot on the other. The connection between the filter cylinder 73 and the cover 74 is achieved through the engagement of the buckle and the slot. No further limitations are imposed here. The above configuration facilitates the disassembly and installation of the cover 74, thereby facilitating the replacement of the filter screen 77. Moreover, the cover 74 and the cylinder 71 cooperate to form a closed space, preventing external impurities from entering the interior of the second filter 7.

[0046] In some embodiments, the top of the cylinder cover 74 is also provided with an exhaust valve, which can remove gas from the cylinder and help the slurry to completely fill the cylinder.

[0047] In some embodiments, a plurality of support legs 76 are provided at intervals along the circumference of the outer wall surface of the cylinder 71, and the lower end of the support legs 76 is provided with an adjustable height support foot 761. With the above arrangement, the cylinder 71 can be effectively supported, and the support foot 761 can be adjusted according to the position where the second filter 7 is installed, thereby facilitating installation.

[0048] In some embodiments, a first sealing ring 78 and a second sealing ring 79 are fitted at both ends of the filter cartridge 73. The first sealing ring 78 is sandwiched between the cartridge cover 74 and the filter cartridge 73, and the second sealing ring 79 is sandwiched between the filter cartridge 73 and the cylinder body 71. By providing the first sealing ring 78 and the second sealing ring 79, leakage of unfiltered slurry can be prevented, thereby ensuring the filtration effect of the second filter 7.

[0049] In some embodiments, a demagnetizing device 8 is provided on the second connecting pipe 12 between the pump 6 and the material box 1. By providing the demagnetizing device 8, ferromagnetic substances in the slurry flowing through the second connecting pipe 12 can be effectively adsorbed, thereby preventing the slurry entering the material box 1 from containing ferromagnetic substances and ensuring that the slurry for subsequent coating can meet the usage requirements.

[0050] In some embodiments, the demagnetizing device 8 includes a support 81, two sets of demagnetizing pipes 83 arranged in parallel, a first switching valve 84, and a second switching valve 85. The demagnetizing pipes 83 are mounted on the support 81. The first switching valve 84 is connected to the pump 6 and the two sets of demagnetizing pipes 83. The second switching valve 85 is connected to the material box 1 and the two sets of demagnetizing pipes 83. Magnetic rods 82 are installed in the demagnetizing pipes 83. By setting the support 81, the two sets of demagnetizing pipes 83 can be quickly installed using mounting parts. The two sets of demagnetizing pipes 83 are arranged in parallel. The slurry enters the two sets of demagnetizing pipes 83 through the first switching valve 84. After being attracted by the magnetic rods 82, it enters the material box 1 through the second switching valve 85. By arranging the two sets of demagnetizing pipes 83, the efficiency of attracting ferromagnetic materials can be guaranteed. Since the magnetic rod 82 needs to be cleaned of foreign objects periodically, by controlling the first switching valve 84 and the second switching valve 85, one set of demagnetizing pipes 83 can be activated while the other set stops working, allowing the magnetic rod 82 to be removed for cleaning. This process can then be repeated to remove another magnetic rod 82 for cleaning. This method saves downtime and ensures production efficiency.

[0051] In some embodiments, a flow meter 86 is provided at the inlet end of the first switching valve 84. By setting the flow meter 86, when the flow rate is abnormally low, it indicates that the filter element in the first filter 4 needs to be cleaned. In this way, it is convenient to detect the condition of the first filter 4.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
