Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a double basket filter that can be processed into pesticide soluble solvent. Background Technology

[0002] Dual basket filters for pesticide soluble concentrate processing are mainly used to filter solutions during the processing of pesticide soluble concentrates, removing impurities and ensuring product quality. This helps pesticide manufacturers strictly control product quality and provides reliable products to downstream users. In pesticide production workshops, these filters are typically installed on the production line to filter freshly prepared soluble concentrates, or at the inlet and outlet of storage tanks to prevent impurities from entering the storage process. Through a dual-filter design, while one filter is filtering, the other can be cleaned or used as a backup, achieving continuous filtration. Currently, the practical application of dual basket filters for pesticide soluble concentrate processing typically requires the following technologies:

[0003] 1. The high-efficiency filter material and structure can effectively intercept various impurities in pesticide soluble agents while ensuring a certain filtration speed.

[0004] 2. Reliable sealing technology prevents pesticide soluble agents from leaking during the filtration process, avoiding environmental pollution and waste of raw materials.

[0005] 3. The convenient filter replacement and cleaning design allows for quick cleaning or replacement of the filter after it becomes clogged, minimizing the impact on production.

[0006] 4. The outer shell material is highly corrosion resistant. Since pesticide soluble agents may be corrosive, it is necessary to ensure that the filter shell can be used stably for a long time.

[0007] Currently, various equipment and methods are used to achieve the cleaning and maintenance function of pesticide soluble filter baskets. A common method is to hold the circular handle at the top of the filter basket and pull it outwards. Foreign objects that have been screened down are removed by scraping with a scraper or by bumping the basket. Then, foreign objects that are clogging the mesh are removed by rinsing with a high-pressure water gun or brushing with a brush.

[0008] For example, a Chinese patent discloses a basket filter (patent number CN222384307U). This filter uses a screen cylinder inside a barrel and a screen structure between the screen cylinder and the outlet of the barrel. When the liquid enters the first filtration space from the inlet, larger solid impurities fall into the storage bin under the filtration effect of the first filter holes on the screen cylinder and gravity. Smaller solid impurities (such as non-magnetic metals like Cu / Zn) enter the second filtration space and fall into the storage bin under the filtration effect of the second filter holes on the screen structure and gravity. This effectively intercepts and filters smaller solid impurities, reducing the number of foreign particles in the liquid.

[0009] However, the above method has a prominent problem: pesticide soluble agents, due to their complex composition and the viscous nature of some solutions, are more prone to clogging than water-based impurities, thus requiring more frequent cleaning and maintenance. Furthermore, since pesticide soluble agents are usually toxic and corrosive, when removing foreign objects from the deeper parts of the filter basket, workers often need to reach into the basket due to its deep inner diameter, making it easier for them to come into contact with the pesticide solution. Moreover, the limited operating space after reaching into the basket makes it difficult to flexibly clean foreign objects from all corners, especially the deeper parts. Therefore, it is particularly important to design a filter basket with a foot-operated quick-release bottom plate, which makes maintenance more convenient and reduces contact. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a double-basket filter for processing pesticide soluble agents. It solves the problems of pesticide soluble agents, due to their complex composition and the viscous nature of some solutions, being more prone to clogging than water-based impurities, thus requiring more frequent cleaning and maintenance. Furthermore, because pesticide soluble agents are typically toxic and corrosive, removing foreign matter from deeper parts of the filter basket often requires workers to reach inside, increasing the risk of contact with pesticide solutions. The limited operating space after reaching inside also hinders the efficient cleaning of all corners, especially deeper areas, of the filter basket.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A double-basket filter for processing pesticide soluble solvents includes two filter bodies, each containing a filter basket cylinder. Each filter basket cylinder has a bottom sieve plate at its lower end. The outer surfaces of both filter basket cylinders and the two bottom sieve plates are equipped with quick-release mechanisms for separate installation. Each quick-release mechanism includes two pressing blocks, two U-shaped locking seats, four springs, and four stainless steel balls. The two pressing blocks are fixedly connected to the outer surfaces of the two bottom sieve plates. The two U-shaped locking seats are fixedly connected to the outer surfaces of the two filter basket cylinders. The four springs are symmetrically arranged inside the two U-shaped locking seats. The four stainless steel balls are slidably connected inside the two U-shaped locking seats and fixedly connected to the outer surfaces of the four springs. The four stainless steel balls are locked onto the outer surfaces of the two pressing blocks. Each of the two U-shaped locking seats has a sealing mechanism for sealing the four stainless steel balls.

[0013] Preferably, the sealing mechanism includes four external threaded covers and four sealing rings, with the four external threaded covers threadedly connected to the inside of two U-shaped retainers.

[0014] Preferably, the four sealing rings are respectively fitted inside the two U-shaped retaining seats.

[0015] Preferably, the four sealing rings are respectively fitted onto the outer surface of the four stainless steel balls.

[0016] Preferably, both filter baskets have a basket handle fixedly connected to their upper ends.

[0017] Preferably, both filter bodies are provided with a top cover at their upper ends.

[0018] Preferably, two sets of on / off valves are fixedly connected to one end of each of the two filter bodies that are close to each other.

[0019] Preferably, both sets of on / off valves have a tee connecting pipe fixedly connected to their outer surfaces.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When cleaning and maintaining the filter basket and bottom screen after removal, the worker steps on the upper surface of the pressing block and pulls the U-shaped clamp upwards by lifting the basket handle. As the U-shaped clamp slides upwards, the two stainless steel balls inside are squeezed by the arc surface of the pressing block, causing them to slide open in opposite directions. During the sliding process, the two springs are compressed and contracted. By stepping on the pressing block and pulling the basket handle, the filter basket and bottom screen are quickly separated. The impurities and foreign objects that have been screened down fall directly outwards with the removal of the bottom screen. Furthermore, during subsequent brushing and rinsing, all parts of the filter basket and bottom screen are directly exposed, allowing the worker to quickly and directly complete the cleaning and maintenance work, further ensuring the thoroughness of the cleaning.

[0029] This application provides a double-basket filter for processing pesticide soluble agents. It effectively solves the problem that pesticide soluble agents, due to their complex composition and the viscous nature of some solutions, are more prone to clogging than aqueous impurities, thus requiring more frequent cleaning and maintenance. Furthermore, because pesticide soluble agents are often toxic and corrosive, removing foreign matter from the deeper parts of the filter basket is difficult. Workers often need to reach into the basket, increasing the risk of contact with the pesticide solution. The limited operating space after reaching in also makes it difficult to flexibly clean all corners, especially the deeper parts, of the filter basket. Cleaning and maintenance after removing the filter basket and bottom sieve plate is also challenging. Workers step on the upper surface of the pressure block and pull the U-shaped clamp upwards by lifting the basket handle. As the U-shaped clamp slides upwards, the two stainless steel balls inside are squeezed by the arc surface of the pressure block, causing them to slide open in opposite directions. During the sliding process, the two springs are compressed and contracted. By stepping on the pressure block and pulling the basket handle, the filter basket and the bottom screen plate are quickly separated. The impurities and foreign objects that have been screened down fall directly out with the removal of the bottom screen plate. In subsequent brushing and rinsing work, all parts of the filter basket and the bottom screen plate can be directly exposed, allowing workers to quickly and directly complete the cleaning and maintenance work, further ensuring the thoroughness of the cleaning.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application effectively solves the problem that pesticide soluble agents, due to their complex composition and the viscous nature of some solutions, are more prone to clogging than aqueous solutions, thus requiring more frequent cleaning and maintenance. Furthermore, because pesticide soluble agents are typically toxic and corrosive, removing foreign matter from the deeper parts of the filter basket often requires workers to reach inside, increasing the risk of contact with the pesticide solution. The limited operating space after reaching inside also hinders the flexible cleaning of all corners of the filter basket. The technical problem of cleaning foreign objects, especially those deep within the filter layer, can be addressed with the following general approach: A double-basket filter for processing pesticide soluble solvents includes two filter bodies 1. Each filter body 1 contains a filter basket cylinder 2. Each filter basket cylinder 2 has a bottom sieve plate 3 at its lower end. The outer surfaces of both filter basket cylinders 2 and the two bottom sieve plates 3 are equipped with quick-release mechanisms for separate installation. These quick-release mechanisms include two pressing blocks 4, two U-shaped locking seats 5, four springs 6, and four stainless steel ball bearings 7. The two pressing blocks 4 are respectively fixedly connected to the two bottom sieve plates. 3. On the outer surface, two U-shaped locking seats 5 are fixedly connected to the outer surfaces of the two filter basket cylinders 2 respectively. Four springs 6 are symmetrically arranged inside the two U-shaped locking seats 5 respectively. Four stainless steel balls 7 are slidably connected inside the two U-shaped locking seats 5 respectively. The four stainless steel balls 7 are fixedly connected to the outer surfaces of the four springs 6 respectively. The four stainless steel balls 7 are locked onto the outer surfaces of the two pressing blocks 4 respectively. When cleaning and maintaining the filter basket cylinders 2 and the bottom sieve plate 3 after removal, the worker steps on the upper surface of the pressing block 4 and pulls the basket by lifting the handle 11 upwards. The U-shaped retainer 5 slides upwards and is removed. When the U-shaped retainer 5 slides upwards, the two stainless steel balls 7 sliding inside are squeezed by the arc surface of the pressing block 4, causing the two stainless steel balls 7 to slide open in opposite directions. During the sliding process, the two springs 6 are compressed and contracted. By stepping on the pressing block 4 and pulling the basket handle 11, the filter basket cylinder 2 and the bottom screen plate 3 are quickly separated. The impurities and foreign objects that are screened down fall directly out as the bottom screen plate 3 is removed. In subsequent brushing and rinsing work, the staff can quickly and directly complete the cleaning and maintenance work.

[0032] Both U-shaped retaining seats 5 are equipped with sealing mechanisms for sealing four stainless steel balls 7. The sealing mechanisms include four external threaded covers 8 and four sealing rings 9. The four external threaded covers 8 are threaded into the interior of the two U-shaped retaining seats 5, and the four sealing rings 9 are fitted into the interior of the two U-shaped retaining seats 5 and onto the outer surface of the four stainless steel balls 7. During filtration, the stainless steel balls 7 achieve a seal by adhering to the sealing rings 9, thereby preventing pesticide solution from flowing into the interior of the U-shaped retaining seats 5 and causing damage. When the stainless steel balls 7 are squeezed and contracted, they are in the removed state and do not come into contact with the pesticide solution.

[0033] Two filter baskets 2 are each fixedly connected to a basket handle 11 at their upper ends. Each of the two filter bodies 1 has a top cover 12 at its upper end. Two sets of on / off valves 13 are fixedly connected to the ends of the two filter bodies 1 that are close to each other. A three-way connecting pipe 14 is fixedly connected to the outer surface of each set of on / off valves 13. The two three-way connecting pipes 14 are divided into upper and lower positions. The upper three-way connecting pipe 14 is used for feeding pesticide soluble concentrate, while the lower three-way connecting pipe 14 is used for discharging. Two on / off valves 13 are installed on both sides of the three-way connecting pipe 14 via flanges. The two on / off valves 13 are then connected to the two filter bodies 1 via flanges. During filtration, one on / off valve 13 is closed, and the other on / off valve 13 is opened. At this time, the filter body 1 on the side with the open on / off valve 13 is in working mode. The pesticide soluble concentrate enters the filter body 1 along the path of the upper three-way connecting pipe 14 and the on / off valve 13, and then passes through the filter body 1. The filter basket cylinder 2 and bottom sieve plate 3 filter impurities and foreign objects carried in the pesticide soluble material. The impurities and foreign objects that pass through the sieve are blocked and remain inside the filter basket cylinder 2 and bottom sieve plate 3. The pesticide soluble material after filtration will be discharged through the lower on / off valve 13 and three-way connecting pipe 14 for subsequent processing and use. The on / off method of the two on / off valves 13 can be quickly switched. When one filter body 1 is blocked, it can be quickly switched to another filter body 1 to continue the filtration work without interrupting the entire production process. When the filter body 1 is idle due to blockage, the top cover 12 at the top of the filter body 1 is removed, and the filter body 1 and filter basket cylinder 2 are pulled outward by holding the basket handle 11. The filter basket cylinder 2 and bottom sieve plate 3 are cleaned and maintained by brushing, high-pressure water washing, etc. The upper surface of the bottom sieve plate 3 is fitted inside the bottom sieve plate 3, which plays a role in the initial fitting and positioning.

[0034] To address the problems existing in the prior art, this utility model provides a double-basket filter for processing pesticide soluble solvents. When cleaning and maintaining the filter basket cylinder 2 and bottom sieve plate 3 after removal, the worker steps on the upper surface of the pressing block 4 and pulls the U-shaped retaining seat 5 upwards by lifting the basket handle 11. As the U-shaped retaining seat 5 slides upwards, the two stainless steel balls 7 sliding inside are squeezed by the arc surface of the pressing block 4, causing the two stainless steel balls 7 to slide open in opposite directions. During the sliding process, the two springs 6 are compressed and contracted. By stepping on the pressing block 4 and pulling the basket handle 11, the filter basket cylinder 2 and bottom sieve plate 3 are quickly separated. Impurities and foreign objects that have been screened out fall directly outwards as the bottom sieve plate 3 is removed. Furthermore, during subsequent brushing and rinsing, all parts of the filter basket cylinder 2 and bottom sieve plate 3 are directly exposed, allowing workers to quickly and directly complete the cleaning and maintenance work, further ensuring thorough cleaning.

[0035] Working principle:

[0036] The first step involves two T-connector pipes 14, one at the top and one at the bottom. The upper T-connector pipe 14 is used for feeding the pesticide soluble concentrate, while the lower T-connector pipe 14 is used for discharging. Two on / off valves 13 are installed on both sides of the T-connector pipe 14 via flanges. These valves 13 are then connected to two filter bodies 1 via flanges. During filtration, one on / off valve 13 is closed, and the other is opened. The filter body 1 on the open side of valve 13 is then in operation. The pesticide soluble concentrate enters the filter body 1 along the path of the upper T-connector pipe 14 and the on / off valves 13. Inside the filter body 1, the filter basket 2 and bottom sieve plate 3 filter out impurities and foreign matter carried in the pesticide soluble concentrate. The impurities that pass through the sieve are then removed. Foreign objects are blocked and remain inside the filter basket 2 and bottom sieve plate 3. The pesticide soluble solution after filtration will be discharged through the lower on / off valve 13 and the three-way connecting pipe 14 for subsequent processing and use. By quickly switching on and off through the on / off valves 13 on both sides, when one filter body 1 becomes blocked, it can be quickly switched to another filter body 1 to continue the filtration work without interrupting the entire production process. When the filter body 1 is idle due to blockage, the top cover 12 at the top of the filter body 1 is removed, and the filter body 1 and filter basket 2 are pulled outward as a whole by holding the basket handle 11. The filter basket 2 and bottom sieve plate 3 are cleaned and maintained by brushing, high-pressure water rinsing, etc. The upper surface of the bottom sieve plate 3 is fitted inside the bottom sieve plate 3, which plays a role in the initial fitting and positioning.

[0037] The second step involves cleaning and maintaining the filter basket and bottom sieve plate 3 after removal. The worker steps on the upper surface of the pressure block 4 and pulls the U-shaped retaining seat 5 upwards by lifting the basket handle 11 (the upper surface of the basket handle 11 is above the liquid level inside the filter body 1 and does not contact the liquid level, therefore it is not contaminated by pesticide solution). As the U-shaped retaining seat 5 slides upwards, the two stainless steel balls 7 inside are squeezed by the arc surface of the pressure block 4, causing the two stainless steel balls 7 to slide open in opposite directions. During the sliding process, the two springs 6 are compressed and contracted. By stepping on the pressure block 4, the basket is pulled... The handle 11 enables the rapid separation of the filter basket cylinder 2 and the bottom sieve plate 3. Impurities and foreign objects that are screened down fall directly out as the bottom sieve plate 3 is removed. In subsequent brushing and rinsing operations, the staff can quickly and directly complete the cleaning and maintenance work. Due to the detachable design of the filter basket cylinder 2 and the bottom sieve plate 3, the thickness of the filter basket cylinder 2 cannot be too thin. During the filtration process, the stainless steel ball 7 is sealed by fitting with the sealing ring 9, thereby preventing pesticide solution from flowing into the U-shaped retainer 5 and causing an impact. When the stainless steel ball 7 is squeezed and contracted, it is already in the removed state and does not come into contact with the pesticide solution.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. 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. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
