Description

Technical Field

[0001] This utility model relates to the field of impurity filtration, and in particular to a high-efficiency water jet cutting circulating water impurity filtration device. Background Technology

[0002] Waterjet cutting, also known as high-pressure water jet cutting, is a process that uses high-pressure water jets to cut workpieces. Under computer control, it can carve any workpiece and is less affected by the material's texture. Because of its low cost, ease of operation, and high yield, waterjet cutting is gradually becoming the mainstream cutting method in industrial cutting technology. During waterjet cutting operations, to save water resources, the water source is usually filtered and recycled.

[0003] A search revealed that the Chinese patent "A Three-Stage Circulating Water Filtration Device for Water Cutting" (authorization announcement number CN219091385U) includes a housing. The top outer wall of the housing has an inlet pipe, and the inner walls of both sides of the housing have the same fixing plate with an inverted "V" shape. The top outer wall of the fixing plate has several water outlet holes. Both outer walls of the housing have sand collection mechanisms, one inner wall of the housing has a baffle, the bottom outer wall of the housing has a sludge removal mechanism, and one outer wall of the housing has a water outlet pipe. This method can improve filtration efficiency, effectively filter impurities in the water, and reduce costs. However, in actual use, the above patent has the following drawbacks: although it can improve filtration efficiency, the filtered impurities are not easily discharged in a timely manner, easily causing blockages and affecting the filtration effect. Furthermore, cleaning impurities requires stopping the machine and disassembling the corresponding components, resulting in low cleaning efficiency and increased user workload.

[0004] Therefore, a high-efficiency water jet cutting circulating water impurity filtration device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency water jet cutting circulating water impurity filtration device to solve the above-mentioned problems, thereby improving the issues of low cleaning efficiency and easy clogging.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a high-efficiency water jet cutting circulating water impurity filtration device, comprising a housing and conduits installed on both sides thereof, wherein a conical filter plate is installed inside the housing; and further comprising a cleaning mechanism, wherein the cleaning mechanism is disposed below the conical filter plate and is used to collect and discharge impurities; wherein, the cleaning mechanism comprises a support plate and two rubber guide rings disposed inside therein, the conical filter plate is mounted on the support plate, the top of the support plate has a groove for connecting the two rubber guide rings, the front view cross section of the rubber guide rings is trapezoidal, the size of the top rubber guide ring is larger than that of the bottom rubber guide ring, and a flushing pipe is disposed below the rubber guide rings in the groove.

[0007] Preferably, the cleaning mechanism further includes a scraper, one side of which is in contact with the conical filter plate.

[0008] Preferably, the bottom of the support plate is provided with a set of filter holes arranged in a ring, and the inside of the support plate is provided with a set of drain outlets.

[0009] Preferably, the housing is provided with a drain pipe, one end of which extends into the groove and is located below the rubber guide ring.

[0010] Preferably, both the flushing pipe and the drain pipe are equipped with solenoid valves on their outer sides, and a magnetic sleeve is threaded onto one end of the drain pipe.

[0011] Preferably, a water pump is provided at the bottom of the housing, the input end of the water pump is connected to one of the conduits, the output end of the water pump is equipped with a drain pipe, and one end of the flushing pipe is connected to the interior of the drain pipe.

[0012] Preferably, one of the conduits has a spiral blade inside, and a rotating shaft is provided inside the spiral blade. One end of the rotating shaft passes through a support plate and a conical filter plate in sequence, and one side of the scraper is installed to the outside of the rotating shaft.

[0013] The beneficial effects of this utility model are:

[0014] By setting up grooves, impurities are collected. When impurities need to be discharged, pressurized water can be introduced into the grooves. Under the influence of water pressure, the two guide rings will deform and fit together, thus ensuring the impact force of the water in the grooves. Subsequently, the water will carry the impurities along the drain pipe to the outside. The whole process does not require stopping the machine or disassembling parts, making the cleaning efficiency higher and reducing the workload of users.

[0015] By installing a scraper, the outer side of the conical filter plate can be continuously scraped during the impurity filtration process, reducing the occurrence of impurity residue clogging and thus ensuring the filtration effect. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, a high-efficiency water jet cutting circulating water impurity filtration device includes a housing 100 and conduits 200 installed on both sides of the housing 100. A conical filter plate 110 is installed inside the housing 100. The device also includes a cleaning mechanism 300, which is located below the conical filter plate 110 and is used to collect and discharge impurities. The cleaning mechanism 300 includes a support plate 310 and two rubber guide rings 320 disposed inside the support plate 310. The conical filter plate 110 is installed on the support plate 310. The top of the support plate 310 has a groove for connecting the two rubber guide rings 320. The front view cross section of the rubber guide rings 320 is trapezoidal. The size of the top rubber guide ring 320 is larger than that of the bottom rubber guide ring 320. A flushing pipe 330 is disposed in the groove below the rubber guide rings 320.

[0023] like Figure 2 As shown, the cleaning mechanism 300 also includes a scraper 340, one side of which is attached to the conical filter plate 110.

[0024] During waterjet cutting, the top conduit 200 can be connected to the water tank in the work area to introduce recycled water into the tank 100. Then, the conical filter plate 110 is used to intercept impurities in the water. During the interception process, the scraper 340 rotates continuously to scrape off the impurities on the conical filter plate 110. Then, the impurities are collected by the groove. At this time, a small amount of water and impurities will be guided by the two rubber guide rings 320 in sequence and placed inside the groove. When impurity cleaning is required, the user can pressurize and discharge the water source along the flushing pipe 330. During the water spraying process, the water pressure will cause the bottom rubber guide ring 320 to deform and move, and fit with the top rubber guide ring 320, so that the water source maintains an impact force, and then flushes out the impurities in the groove, completing the impurity cleaning.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, a set of filter holes 311 arranged in a ring are provided at the bottom of the support plate 310, and a set of drain outlets are provided inside the support plate 310.

[0026] The drain outlet allows most of the water on the guide cone filter plate 110 to be discharged, while the filter holes 311 allow the remaining small portion of water to be discharged, and at the same time intercepts impurities in the groove.

[0027] like Figure 1 and Figure 2 As shown, a drain pipe 120 is provided on the box 100, and one end of the drain pipe 120 extends into the groove and is located below the rubber guide ring 320.

[0028] During the impurity discharge process, the water source during the impact process will carry impurities and discharge them to the outside through the sewage pipe 120. During this process, the water circulation operation continues without the need to stop the machine for treatment.

[0029] like Figure 1 and Figure 2 As shown, solenoid valves are installed on the outside of both the flushing pipe 330 and the drain pipe 120, and a magnetic sleeve is threaded onto one end of the drain pipe 120.

[0030] By using the corresponding solenoid valve settings, the opening and closing of the flushing pipe 330 and the drain pipe 120 can be controlled. When it is necessary to drain, the two solenoid valves can be opened.

[0031] The system employs a magnetic sleeve to collect magnetic metal materials that can be adsorbed during the sewage discharge process, thereby reducing resource waste.

[0032] like Figure 1 and Figure 2As shown, a water pump 130 is installed at the bottom of the housing 100. The input end of the water pump 130 is connected to one of the conduits 200, and a drain pipe 140 is installed at the output end of the water pump 130. One end of the flushing pipe 330 is connected to the inside of the drain pipe 140.

[0033] When the water pump 130 is started, the water source in the tank 100 can be drawn out through the bottom conduit 200 and then discharged into the water-using area in the water jet cutting through the drain pipe 140. When the sewage discharge operation is in progress, a small amount of pressurized water can be discharged through the flushing pipe 330.

[0034] like Figure 2 As shown, a spiral blade 210 is provided inside one of the conduits 200, and a rotating shaft 211 is provided inside the spiral blade 210. One end of the rotating shaft 211 passes through the support plate 310 and the conical filter plate 110 in sequence, and one side of the scraper 340 is installed on the outside of the rotating shaft 211.

[0035] During the operation of the water pump 130, when the water source flows through the corresponding conduit 200, it will drive the spiral blade 210 to rotate, and then the rotating shaft 211 will follow suit, thereby driving the scraper 340 to continuously scrape away impurities from the outside of the conical filter plate 110.

[0036] Working Principle: During waterjet cutting, the top conduit 200 can be connected to the water tank in the work area to introduce recycled water into the tank 100. Then, a conical filter plate 110 intercepts impurities in the water. The drain outlet allows most of the water on the conical filter plate 110 to be discharged. During interception, a scraper 340 driven by a spiral blade 210 continuously rotates, scraping away impurities on the conical filter plate 110. The impurities are then collected using grooves. A small amount of water and impurities are guided sequentially by two rubber guide rings 320 into the grooves. Combined with the filter holes 311, the remaining small amount of water can be filtered. The system discharges water while simultaneously intercepting impurities within the groove. When impurity cleaning is required, the drain pipe 140 on the water pump 130 pressurizes and discharges some water along the flushing pipe 330. During the spraying of this water, the water pressure causes the bottom rubber guide ring 320 to deform and move, fitting against the top rubber guide ring 320, maintaining the impact force of the water. This flushes the impurities in the groove into the drain pipe 120, which is then discharged to the outside, completing the impurity cleaning. The entire device reduces clogging during the filtration process, ensuring filtration efficiency. Furthermore, impurity cleaning does not require stopping the machine or disassembling parts, resulting in higher cleaning efficiency and reducing the user's workload.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
