Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a filtration device for an anti-clogging fiberboard washing machine. Background Technology

[0002] In the field of electronic substrate manufacturing, fiberboard is a key basic material, and its quality has a crucial impact on the performance of electronic substrates. During the production process, dust easily adheres to the surface of fiberboard. If this dust is not thoroughly removed, it will seriously affect the quality stability of electronic substrates, potentially leading to a series of problems such as poor soldering of electronic components and decreased insulation performance, thereby affecting the reliability and service life of the entire electronic product. Therefore, effective water washing of fiberboard is an indispensable key step in the production process of electronic substrates.

[0003] After the washing machine finishes cleaning the substrate, the wastewater generated must be purified by a special filtration device before it can be discharged or recycled. Because the wastewater contains a large number of particulate impurities washed off from the substrate, the core filtration components of the filtration device will quickly accumulate impurities after long-term operation, causing serious blockage, resulting in a sharp drop in filtration efficiency and an increase in system pressure.

[0004] To restore filtration performance, current maintenance methods typically require manual removal of clogged filter components from the unit for offline flushing or replacement, followed by reinstallation. This process is cumbersome, time-consuming, and costly, severely hindering production efficiency and representing a critical industry pain point that urgently needs to be addressed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-clogging filter device for fiberboard washing machines, thereby solving the problems mentioned in the background art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A filter device for an anti-clogging fiberboard washing machine includes a lower cylinder and an upper cylinder. A transfer pipe is installed on the bottom outer wall of the lower cylinder, and an externally threaded pipe is installed on the bottom inner wall of the lower cylinder, communicating with the transfer pipe. A filter cylinder is screwed onto the outer wall of the externally threaded pipe, and the filter cylinder is located inside the lower and upper cylinders. A water inlet pipe is connected to one side of the outer wall of the transfer pipe through an opening. A drain pipe is connected to one side of the bottom outer wall of the lower cylinder through an opening. A positioning cylinder is fixedly installed at the top center of the upper cylinder through an opening. A backwash pipe is connected to the top center of the positioning cylinder through an opening. A sewage discharge pipe is connected to the other side of the transfer pipe through an opening. A vertically downward rotating rod is provided inside the positioning cylinder. Equally spaced blades are fixedly installed on the top outer wall of the rotating rod, and the blades are located inside the positioning cylinder. Two vertical positioning plates are fixedly installed on the outer wall of the rotating rod by a bracket. Brushes are adhered to the outer wall of the positioning plates, and the brushes are close to the inner wall of the filter cylinder.

[0008] As a preferred embodiment of the anti-clogging fiberboard washing machine filter device, the inner wall of the positioning cylinder is fixedly provided with a first fixing ring by a bracket, the inner wall of the first fixing ring is fixedly provided with a first bearing, the inner ring of the first bearing is fixedly connected to the top outer wall of the rotating rod, and the top center position of the filter cylinder is fixedly provided with a second fixing ring through an opening, the inner wall of the second fixing ring is fixedly provided with a second bearing, and the inner ring of the second bearing is fixedly connected to the outer wall of the rotating rod.

[0009] As a preferred embodiment of the filter device for an anti-clogging fiberboard washing machine, the top of the lower cylinder and the bottom of the upper cylinder are connected by threads.

[0010] As a preferred embodiment of the anti-clogging filter device for a fiberboard washing machine, a first electrically controlled valve is installed on the inlet pipe, and a second electrically controlled valve is installed on the drain pipe, with the first and second electrically controlled valves opening and closing synchronously.

[0011] As a preferred embodiment of the filter device for an anti-clogging fiberboard washing machine, a third electrically controlled valve is installed on the backwash pipe, and a fourth electrically controlled valve is installed on the drain pipe. The third and fourth electrically controlled valves open and close synchronously.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This utility model adds a backwash pipe structure design to the filter device.

The collection bottle is connected to the bottom of the transfer tube by a thread. After a period of use, the collection bottle can be directly disassembled for cleaning, thereby reducing the number of maintenance times of backwashing of the filter cartridge.

[0031] Example 1:

[0032] like Figures 1 to 7As shown, this embodiment provides a filter device for an anti-clogging fiberboard washing machine, including a lower cylinder 1 and an upper cylinder 2. The top of the lower cylinder 1 and the bottom of the upper cylinder 2 are tightly connected by threads for easy disassembly and installation, and the connection is sealed by a sealing ring. A transfer pipe 3 is installed at the center of the bottom outer wall of the lower cylinder 1, and an externally threaded pipe 12 is installed on the bottom inner wall of the lower cylinder 1. The externally threaded pipe 12 is connected to the transfer pipe 3. A filter cylinder 13 is screwed to the outer wall of the externally threaded pipe 12. The filter cylinder 13 is located in the internal space enclosed by the lower cylinder 1 and the upper cylinder 2. The outer wall of the filter cylinder 13 is provided with equally spaced filter holes with a diameter of 0.5 mm for filtering wastewater entering the device.

[0033] An opening is made on one side of the outer wall of the transfer pipe 3 and connected to the water inlet pipe 4. A first electric control valve 8 is installed on the water inlet pipe 4. An opening is made on one side of the bottom of the lower cylinder 1 and connected to the drain pipe 5. A second electric control valve 9 is installed on the drain pipe 5, and the first electric control valve 8 and the second electric control valve 9 open and close synchronously. Pipe joints are installed at one end of the water inlet pipe 4 and the drain pipe 5, which can be connected to the external water supply pipe. The wastewater from the washing machine enters through the water inlet pipe 4, is filtered by the filter cartridge 13, and is finally discharged through the drain pipe 5.

[0034] To prevent filter cartridge 13 from clogging, an opening is made at the center of the top of the upper cylinder 2, connecting to the positioning cylinder 24. A backwash pipe 6 is connected to the center of the top of the positioning cylinder 24, and a third electrically controlled valve 10 is installed on the backwash pipe 6. An opening is made on the other side of the transfer pipe 3, connecting to the drain pipe 7, and a fourth electrically controlled valve 11 is installed on the drain pipe 7. The third and fourth electrically controlled valves 10 and 11 open and close synchronously. Pipe fittings are installed at one end of both the backwash pipe 6 and the drain pipe 7 for connection to external pipelines. When it is necessary to clean impurities, clean water is filled into the backwash pipe 6 to clean the inside of the filter cartridge 13, and finally discharged through the drain pipe 7.

[0035] Meanwhile, a vertically downward rotating rod 20 is provided inside the positioning cylinder 24. A first fixing ring 16 is installed inside the positioning cylinder 24 via a bracket. A first bearing 17 is fixed to the inner wall of the first fixing ring 16. The inner wall of the first bearing 17 is fixedly connected to the outer wall of the rotating rod 20. A second fixing ring 18 is fixed to the top center of the filter cylinder 13 through an opening. A second bearing 19 is installed on the inner wall of the second fixing ring 18. The inner wall of the second bearing 19 is fixedly connected to the outer wall of the rotating rod 20. The first bearing 17 and the second bearing 19 are ceramic bearings. The second bearing 19 facilitates the rotation of the rotating rod 20. The outer wall of the rotating rod 20 is fixed with equally spaced blades 21, which are located inside the positioning cylinder 24. When the backwash pipe 6 is connected to the water source, water is injected into the upper cylinder 2 through the positioning cylinder 24. The water can drive the blades 21 to rotate, thereby driving the rotating rod 20 to rotate. The outer wall of the rotating rod 20 is fixed with two positioning plates 22 by the bracket. The outer walls of the two positioning plates 22 are attached with brushes 23. The brushes 23 are close to the inner wall of the filter cylinder 13, which facilitates the removal of impurities attached to its filter holes.

[0036] Example 2:

[0037] Based on Embodiment 1, this embodiment further optimizes the filtration device of the fiberboard washing machine. In this embodiment, a collection bottle 14 is set below the transfer pipe 3, and an externally threaded bottle mouth 15 is set at the top of the collection bottle 14. The top outer wall of the externally threaded bottle mouth 15 is threadedly connected to the bottom inner wall of the transfer pipe 3, so that the collection bottle 14 is located directly below the filter cylinder 13, and is used for daily collection of impurities filtered out by the filter cylinder 13.

[0038] Working principle and usage process of this utility model:

[0039] Refer to the instruction manual appendix Figure 1-7 When using the fiberboard washing machine filtration device of this utility model, the first solenoid valve 8 and the second solenoid valve 9 are opened simultaneously. The water to be filtered enters the filter cylinder 13 from the inlet pipe 4 through the transfer pipe 3 and the external threaded pipe 12 for filtration. The filtered water flows into the lower cylinder 1 and is discharged from the drain pipe 5. After filtration, some impurities in the filter cylinder 13 fall into the collection bottle 14.

[0040] After filtering for a period of time, a lot of impurities will accumulate on the surface of the filter cartridge 13. At this time, the first solenoid valve 8 and the second solenoid valve 9 are closed to stop the normal filtration process. Then, the third solenoid valve 10 and the fourth solenoid valve 11 are opened synchronously. Clean water enters the positioning cylinder 24 from the backwash pipe 6, and then enters the interior of the lower cylinder 1 and the upper cylinder 2 to backwash the filter cartridge 13, flushing down the impurities inside the filter cartridge 13. The impurities are discharged with the water flow through the transfer pipe 3 and the drain pipe 7, and some impurities fall into the collection bottle 14.

[0041] During the backwashing process, water flows through the interior of the positioning cylinder 24, and its blades 21 will drive the rotating rod 20 to rotate. The rotating rod 20 drives the positioning plate 22 to rotate inside the filter cylinder 13. The brush 23 on the outer wall of the positioning plate 22 can brush off the impurities that clog the filter cylinder 13, preventing the holes from clogging and providing a good anti-clogging effect.

[0042] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
