Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically to a circulation system for aluminum wire drawing fluid. Background Technology

[0002] Pure oil-based aluminum alloy lubricating oil is mainly composed of base oil (usually mineral oil), extreme pressure anti-wear agents, and other functional additives. Under high-temperature friction conditions, its composition is prone to change and corresponding substances are produced. When the operating temperature exceeds a certain range, the base oil will evaporate or pyrolyze, generating volatile organic compounds such as alkanes, alkenes, and aromatic hydrocarbons. Extreme pressure anti-wear agents containing phosphorus, sulfur, and chlorine may decompose at high temperatures, releasing small amounts of irritating or toxic gases such as hydrogen chloride, hydrogen sulfide, and phosphine. Additives such as antioxidants and defoamers will also undergo complex decomposition reactions under high-temperature conditions, generating corresponding products. At the same time, high-speed friction and agitation will cause the lubricating oil to form a large number of micron-sized liquid droplets, suspended in the air, forming a visible oil mist.

[0003] After a period of time, a large amount of aluminum ash will accumulate in the pure aluminum drawing lubricating oil, and the lubricating oil will also change from its original brownish color to grayish black. Although a centrifuge can partially remove the aluminum sludge, smaller aluminum powder particles cannot be eliminated and remain suspended in the lubricating oil. When workers operate the drawing equipment to start the machine and thread the die, a certain amount of lubricating oil will leak out. Once the grease leaks, it will be difficult to clean it up and will affect the surrounding environment.

[0004] When oil-based aluminum drawing oil is in operation, the aluminum rod being drawn in the die generates a large amount of frictional heat, which causes the lubricating oil temperature to rise rapidly. Once the temperature rises and exceeds the operating temperature, it becomes very difficult to lower because the oil-based lubricating oil has a high viscosity and slow flow rate, and the heat exchanger is unable to remove so much heat, resulting in ineffective cooling. If the temperature rises further to the oil's flash point, sparking will occur.

[0005] A certain amount of pure oil lubricant is required for the wire drawing machine to work properly. This amount is no longer sufficient once the ash content of the lubricant exceeds a certain value, and the oil must be replaced with new oil.

[0006] When drawing irregularly shaped wires, the shape characteristics of the single wire require that the direction of each die be kept consistent. Therefore, the exit die cannot rotate like when drawing round wires, which causes aluminum ash to flow out unevenly at the die opening, resulting in blockage. This leads to frequent wire breakage or increased wear on the die during the production process.

[0007] Therefore, this application proposes a circulation system for aluminum drawing fluid. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of the above-mentioned technologies by proposing a circulation system for aluminum wire drawing fluid. This system aims to solve the problem that after a period of wire drawing operation, a large amount of aluminum ash accumulates in the pure oil aluminum drawing lubricating oil. When drawing irregularly shaped wires, the exit die cannot rotate as it does when drawing round wires, causing the aluminum ash to flow unevenly out of the die opening and resulting in blockage. This leads to frequent wire breakage or increased die wear during the production process.

[0009] This invention provides a circulation system for aluminum drawing fluid, comprising:

[0010] The wire drawing equipment has an outlet die and an immersion tank. After the aluminum rod enters the immersion tank and is drawn, it is sized and formed from the outlet die.

[0011] The drawing liquid tank is equipped with a filter. The filter is connected to the immersion tank through a circulation pipe. A heat exchanger is connected to the circulation pipe. The immersion tank is connected to the drawing liquid tank through a return pipe.

[0012] The cooling system is connected to the heat exchanger via circulation pipe two;

[0013] The filter has multiple continuous filtration mechanisms, which are configured to switch to a new filtration structure when the water level inside the filter rises.

[0014] Preferably, the filter includes a box with an opening at the bottom, and the continuous filtration mechanism includes a rotating filter cavity, a driven roller one, and a driven roller two. The rotating filter cavity is rotatably disposed in the box, and the driven roller one and driven roller two are rotatably disposed in the box and located on both sides of the upper end of the rotating filter cavity, so that the filter structure moving from the driven roller one is arranged around the rotating filter cavity and then exits through the driven roller two, so that the rotating filter cavity and the filter structure form a circular filter cavity structure.

[0015] Preferably, a hollow tube is provided in the middle of the rotating filter chamber, and several through holes are opened on the hollow tube; the first circulation pipe is rotatably connected to the hollow tube. Circular plates are provided at both ends of the rotating filter chamber, and the filter structure is wrapped around the circular plates, so that the hollow cavity between the filter structure and the circular plates forms a circular filter chamber structure, so that the filtered drawing liquid can enter the first circulation pipe through the hollow tube in the middle of the circular filter chamber structure.

[0016] Preferably, the continuous filtration mechanism further includes a drive motor and at least two discharge rollers. The drive motor is located on one side of the housing, and the discharge rollers are located at the discharge port of the housing. The drive motor is connected to one of the discharge rollers via a reducer, and the ends of the discharge rollers are driven by a linkage gear.

[0017] Preferably, a support frame is inclinedly arranged on one side of the housing, and a rotating rod is arranged on the support frame. The filter structure is an 800-mesh non-woven fabric with a roll structure. The filter structure is rotatably sleeved on the rotating rod and passes through the feed port on one side of the housing and is wound around the driven roller. A liquid level sensor is installed inside the filter.

[0018] Preferably, the outlet mold includes a sizing mold and a mold base. The mold base is installed at one end of the immersion tank, and the sizing mold is disposed on the mold base. The mold base is provided with multiple grooves, which fit against the back of the sizing mold.

[0019] Preferably, the cooling system includes a cooling pool and a cooling tower, with the cooling tower located above the cooling pool. The cooling pool is connected to the cooling tower via a second circulation pipe. Water pumps are connected to both circulation pipes. The cooling water in the cooling pool is deionized water. The aluminum wire drawing lubricant used is formed by mixing water-based aluminum wire drawing crude oil and deionized water in a 1:3 ratio.

[0020] Preferably, the drawing fluid tank includes a submerged cement tank and a stainless steel tank, with the stainless steel tank located within the cement tank. The heat exchanger is a double-plate heat exchanger.

[0021] Preferably, the continuous filtration mechanism further includes driven roller three and driven roller four rotatably disposed within the housing, and four discharge rollers, which are driven by meshing gears. Driven roller three and driven roller four are vertically positioned above driven roller one and driven roller two, respectively. Several support rollers are arranged circumferentially on the circular plate. The filtration structure consists of two sets. One filtration structure is sequentially wound around driven roller three, support rollers, and driven roller four, and emerges from the vertical gap between the four discharge rollers. The other filtration structure is sequentially wound around driven roller one, circular plate, and driven roller two, and emerges from the lower horizontal gap between the four discharge rollers.

[0022] Compared with existing technologies, it has the following beneficial effects:

[0050] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0051] Example 1:

[0052] like Figures 1 to 7 As shown, the present invention provides a circulation system for aluminum drawing fluid, comprising:

[0053] The wire drawing equipment 1 has an outlet die 11 and an immersion tank 12. After the aluminum rod enters the immersion tank 12 and is drawn, it is sized and formed from the outlet die 11.

[0054] The drawing liquid tank 2 is equipped with a filter 4. The filter 4 is connected to the immersion tank 12 through a circulation pipe 5. A double plate heat exchanger 7 is connected to the circulation pipe 5. The immersion tank 12 is connected to the drawing liquid tank 2 through a return pipe 9.

[0055] Cooling system 3 is connected to heat exchanger 7 via circulation pipe 2 6;

[0056] The filter 4 has multiple continuous filtration mechanisms 41. The continuous filtration mechanism 41 is configured to rotate when the water level in the filter 4 rises, thereby switching to a new filtration structure 42. This facilitates the filtration of aluminum powder in the drawing liquid pool 2 and the recirculation of the filtered drawing liquid to the immersion tank 12 of the drawing equipment 1 through the circulation pipe 5. This achieves the purification and circulation of the drawing liquid, resulting in good lubrication performance and a smooth aluminum wire surface.

[0057] See Figures 3 to 5 The filter 4 includes a housing 43 with an opening at the bottom. The continuous filtration mechanism 41 includes a rotating filter chamber 411, a driven roller 1 412, and a driven roller 2 413. The rotating filter chamber 411 is rotatably disposed inside the housing 43. The driven roller 1 412 and the driven roller 2 413 are rotatably disposed inside the housing 43 and located on both sides of the upper end of the rotating filter chamber 411. The filter structure 42, which moves from the driven roller 1 412, is wound around the rotating filter chamber 411 and then exits through the driven roller 2 413, so that the rotating filter chamber 411 and the filter structure 42 form a circular filter chamber structure. The drawing fluid in this circular filter chamber structure is the filtered drawing fluid, that is, the lubricating oil after filtering aluminum powder.

[0058] See Figure 5 A hollow tube 4111 is provided in the middle of the rotating filter chamber 411, and several through holes 4112 are opened on the hollow tube 4111. The circulation pipe 5 is rotatably connected to the hollow tube 4111 through a sealed bearing. Circular plates 4113 are provided at both ends of the rotating filter chamber 4111, and the two circular plates 4113 are connected by the hollow tube 4111. One end of the hollow tube 4111 is a closed structure, and the other end is connected to the circulation pipe 5 through a sealed bearing. The filter structure 42 is wound around the circular plate 4113, so that the hollow cavity between the filter structure 42 and the circular plate 4113 forms a circular filter chamber structure, so that the filtered drawing liquid can enter the circulation pipe 5 through the hollow tube 4111 in the middle of the circular filter chamber structure, and then flow back to the immersion tank 12 by pumping.

[0059] Specifically, the circular plate 4113 has a certain thickness, which allows the filter structure 42 wrapped around it to move stably on it and drive the rotating filter chamber 411 to rotate in the drawing liquid pool 2.

[0060] See Figures 5 to 7 The continuous filtration mechanism 41 also includes a drive motor 414 and at least two discharge rollers 415. The drive motor 414 is located on one side of the housing 43, and the discharge rollers 415 are located at the discharge port of the housing 43. The drive motor 414 is connected to one of its discharge rollers 415 via a reducer, and the ends of the discharge rollers 415 are driven by a linkage gear 46. The drive motor 414 drives one of its discharge rollers 415 to rotate, and drives the other discharge roller 415 to move synchronously in the opposite direction by relying on the linkage gear 46 at its end. This causes the filter structure 42 clamped between them to move under the rotation of the discharge rollers 415, thereby switching the circular filter chamber structure to a new filter structure 42.

[0061] Furthermore, the reducer at the output end of the drive motor 414 can be connected to one end of the hollow tube 4111 via a sprocket and chain to drive the rotating filter chamber 411 to rotate within the housing 43 when the drive motor 414 is working. Alternatively, the rotating filter chamber 411 can be driven to rotate within the housing 43 by connecting it to one end of the hollow tube 4111 via a sprocket and chain at the end of one of its discharge rollers 415.

[0062] See Figure 3 A support frame 44 is inclinedly arranged on one side of the housing 43, and a rotating rod is arranged on the support frame 44. The filter structure 42 is an 800-mesh non-woven fabric with a roll structure. The filter structure 42 is rotatably sleeved on the rotating rod and passes through the feed port on one side of the housing 43 and is wound around the driven roller 412. Furthermore, slots for placing the rotating rod are inclined or vertically arranged on the upper part of both ends of the support frame 44. Rotary rings with openings are rotatably arranged on the slots to facilitate the closing and opening of the slots.

[0063] Specifically, the 800-mesh nonwoven fabric can effectively filter aluminum powder while retaining the original lubricating grease. The liquid level of the drawing fluid on the nonwoven fabric will rise. At this time, the liquid level sensor installed in the filter 4 will be buoyed by the rising water level, which will cause the drive motor 414 to connect the circuit to drive the two discharge rollers 415 to rotate, thereby driving the nonwoven fabric filter structure 42 to rotate and switch, so as to continuously use new nonwoven fabric for aluminum powder filtration.

[0064] Further, see Figure 5 The top of the housing 43 is equipped with an openable and closable screen, which allows the filtration of the drawing liquid in the circular filter chamber structure inside the housing 43 to be viewed by opening the screen.

[0065] Further, see Figure 4 A storage box is provided on one side of the box 43, which is located below the discharge roller 415 to collect the non-woven fabric coming out of the box 43.

[0066] See Figure 1 The cooling system 3 includes a cooling pool 31 and a cooling tower 32. The cooling tower 32 is located above the cooling pool 31, and the cooling pool 31 is connected to the cooling tower 32 via a circulation pipe 6. The cooling water in the cooling pool 31 is deionized water. The aluminum wire drawing lubricant used is formed by mixing water-based aluminum wire drawing crude oil and deionized water in a 1:3 ratio. After mixing, the odor of the crude oil is basically masked. Even when the temperature rises, the water molecules emitted will not have a noticeable pungent odor, making it environmentally friendly. At the same time, the water-based lubricant has a cleaning function, which can remove and clean the residual aluminum dust inside the equipment. Therefore, the workers are clean, and the machine is hygienic.

[0067] A water pump 8 is connected to circulation pipe 5 and circulation pipe 6. The water pump 8 with a certain power draws the drawing liquid from the drawing liquid pool 2 into the drawing equipment 1, and then returns it to the filter 4 through the heat exchanger 7 and then filters it back into the drawing liquid pool 2.

[0068] A water pump 8 of a certain power is used to draw cooling water from the cooling pool 31 and pass it through the circulation pipe to the heat exchanger 7. The double-plate heat exchanger 7 efficiently transfers the heat of the drawing fluid to the cooling water, thereby reducing the temperature of the drawing fluid itself. The deionized cooling water used can be used for a long time without causing scale buildup inside the heat exchanger 7, which would cause blockage and loss of heat exchange efficiency. The water then flows back to the cooling tower 32 for circulation. The cooling tower 32 can pass the heated cooling water through the water flow aerator at the top of the tower. During the fall, a small amount of water will evaporate, thereby transferring heat to the air to reduce the temperature of the cooling water.

[0069] The water-based aluminum drawing lubricant of this invention generates aluminum powder during the aluminum drawing process, which can reduce lubrication performance when it accumulates to a certain extent. Therefore, a filter structure 42 with 800-mesh nonwoven fabric is used to filter the aluminum powder, removing aluminum powder particles and impurities larger than 10µm (because the diameter of oil droplets in the drawing fluid is generally 0.1-10µm) while retaining the lubricating grease. This ensures that the lubrication performance of the water-based lubricant is not affected and extends its service life. The filter 4 uses a liquid level sensor for automatic paper feeding.

[0070] See Figure 1 and Figure 10 The wire drawing liquid pool 2 includes a sunken cement tank and a stainless steel pool 21. The stainless steel pool 21 is set inside the cement tank. The stainless steel pool is made of 304 stainless steel plate with a thickness of 4mm and is reinforced with stainless steel rectangular tubes around it to prevent thermal expansion and contraction deformation and weld cracking caused by temperature changes during the wire drawing liquid operation.

[0071] Working principle of this invention: After the aluminum rod is drawn into the immersion tank 12, it is sized and formed from the exit die 11. During this process, the drawing liquid is pumped from the drawing liquid pool 2 into the immersion tank 12 through the circulation pipe 1 5 to lubricate, clean, and remove heat from the aluminum rod. The drawing liquid containing aluminum powder in the immersion tank 12 flows back to the drawing liquid pool 2 through the return pipe 9. The drawing liquid in the drawing liquid pool 2 enters the filter 4 box 43 through the bottom opening of the filter 4 box 43, and enters the circular filter cavity structure composed of the rotating filter cavity 411, driven roller 1 412, driven roller 2 413, and the filter structure 42 through the filter structure 42. After entering the hollow tube 4111 through the through hole 4112, it is pumped back into the immersion tank 12 through the circulation pipe 1 5. The heat exchanger 7 on the circulation pipe 1 5 cools the drawing liquid, and the removed heat enters the cooling system through the circulation pipe 2 6 for circulation.

[0072] Example 2:

[0073] As another embodiment of the present invention, such as Figure 2 As shown, the outlet die 11 includes a sizing die 111 and a die base 112. The die base 112 is installed at one end of the immersion tank 12, and the sizing die 111 is placed on the die base 112. Multiple grooves 113 are provided on the die base 112, and the grooves 113 are fitted to the back of the sizing die 111. During the wire drawing process, the drawing fluid flows slowly out through the grooves 113, wetting and draining the accumulated aluminum powder at the outlet, preventing the aluminum powder from flying everywhere and avoiding its accumulation and clogging of the die orifice. The main functions of the drawing fluid are lubrication, cleaning, and heat removal. When the metal rod is drawn through the drawing die, a lubricant is needed at the die opening of the sizing die 111 for lubrication; otherwise, the wire drawing cannot proceed smoothly. When the drawing fluid passes through the sizing die 111, it forms an oil film of a certain thickness between the die opening and the rod, thereby reducing the coefficient of friction. Simultaneously, the aluminum powder generated during the drawing process is carried away and filtered by the drawing fluid.

[0074] Example 3:

[0075] As another embodiment of the present invention, such as Figure 8 As shown, the continuous filtration mechanism 41 also includes a driven roller three 416 and a driven roller four 417 rotatably disposed within the housing 43. The driven roller three 416 is rotatably disposed vertically above the driven roller one 412, and the driven roller four 417 is rotatably disposed vertically above the driven roller two 413. There are four discharge rollers 415, which are driven by meshing gears 46. Several support rollers 418 are arranged circumferentially on the circular plate 4113. The filtration structure 42 consists of two sets. One filtration structure 42 is wound sequentially around the driven roller three 416, the support rollers 418, and the driven roller four 417, and emerges from the vertical gap between the four discharge rollers 415. The other filtration structure 42 is wound sequentially around the driven roller one 412, the circular plate 4113, and the driven roller two 413, and emerges from the lower horizontal gap between the four discharge rollers 415.

[0076] Specifically, the four discharge rollers 415 include a first discharge roller 4151, a second discharge roller 4152, a third discharge roller 4153, and a fourth discharge roller 4154. One end of the first discharge roller 4151 is connected to the gearbox at the output of the drive motor 414. The ends of the second discharge roller 4152 and the third discharge roller 4153 are connected to the end of the first discharge roller 4151 via a linkage gear 46. The end of the fourth discharge roller 4154 is connected to the third discharge roller 4153 via a linkage gear 46. This allows the first discharge roller 4151 to rotate, which in turn drives the second discharge roller 4152 and the third discharge roller 4153 to rotate synchronously in opposite directions. The fourth discharge roller 4154 rotates in the same direction as the first discharge roller 4151, so that the two sets of filter structures 42 can be discharged simultaneously, and the new filter structure 42 on the rotating filter chamber 411 can be switched simultaneously.

[0077] Further, see Figure 8 The two sets of filter structures 42 include a first filter structure 421 and a second filter structure 422. The first filter structure 421 is wound around the driven roller 1 412, the circular plate 4113, the driven roller 2 413, and the third and fourth discharge rollers 4153 and 4154. The second filter structure 422 is wound around the driven roller 3 416, the support roller 418, the driven roller 417, and the first and second discharge rollers 4151 and 4152, so that the filter structure 42 forms two layers of filter areas within the rotating filter cavity 411, namely an 800-mesh annular filter cavity and a secondary filter cavity with a mesh size of less than 800 mesh. Specifically, it can also be a double 800-mesh filter structure 42, that is, the first filter structure 421 is 800-mesh nonwoven fabric, and the second filter structure 422 is a filter structure with a mesh size of less than or equal to 800 mesh. Further, the first filter structure 421 can use nonwoven fabric with a mesh size greater than 800 mesh, and the second filter structure 422 can use 800-mesh nonwoven fabric.

[0078] Example 4:

[0079] As another embodiment of the present invention, such as Figure 9As shown, the second discharge roller 4152 is rotatably connected to both ends with annular limiting members. The annular limiting members are slidably disposed in limiting grooves on the mounting brackets on both sides of the housing 43. The first discharge roller 4151 and the second discharge roller 4152 are rotatably disposed on the mounting brackets. An adjusting member 45 is provided penetrating one end of the limiting groove. The adjusting member 45 is a screw or an electric telescopic rod. One end of the adjusting member 45 is rotatably or fixedly connected to the annular limiting member, so as to adjust the distance between the first discharge roller 4151 and the second discharge roller 4152 by adjusting the adjusting member 45. When it is necessary to control the movement and switching of the first filter structure 421 independently, the adjusting member 45 rotates or retracts to push the second discharge roller 4152 to move away from the first discharge roller 4151. At this time, the pressure roller 419, located above the driven roller 417 inside the housing 43, descends and presses the second filter structure 422 under the action of the electric telescopic rod 47. The drive motor 414 starts to control the first discharge roller 4151 to work and drive the third discharge roller 4153 to move together. Since the second discharge roller 4152 is away from the first discharge roller 4151 at this time, its linkage gear 46 also disengages at the same time to realize the independent switching of the first filter structure 421. When it is necessary to simultaneously switch the first filter structure 421 and the second filter structure 422 to a new filter structure 42, the adjusting member 45 drives the second discharge roller 4152 to move and mesh with the linkage gear 46 on the first discharge roller 4151. The pressure roller 419 rises under the action of the electric telescopic rod 47 to release the degree of freedom of movement of the second filter structure 422. At this time, the drive motor 414 works, and the first discharge roller 4151 drives the second discharge roller 4152 and the third discharge roller 4153 to rotate together to synchronously pull the first filter structure 421 and the second filter structure 422 to switch to the new filter structure 42.

[0080] Further, see Figure 9 The idler roller 418 can be replaced by an annular protrusion 4114 to provide stable support for the second filter structure 422, so that it can move stably within the rotating filter chamber 411 under the drive of the discharge roller 415.

[0081] This embodiment achieves secondary continuous filtration of the drawing liquid by setting a double-layer filter structure 42 and relying on the multiple filter chambers composed of the double-layer filter structure 42. The filtration efficiency is high and it is easy to replace the new filter structure 42, so that it can continuously perform filtration without stopping the machine to disassemble the internal filter structure 42 for replacement. It is only necessary to connect the end of the non-woven fabric of the filter structure 42 that is about to be used up to the end of the non-woven fabric of the new filter structure 42.

[0082] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.

The filter (4) includes a box (43) with an opening at the bottom. The continuous filtration mechanism (41) includes a rotating filter cavity (411), a driven roller one (412), and a driven roller two (413). The rotating filter cavity (411) is rotatably disposed inside the box (43). The driven roller one (412) and the driven roller two (413) are rotatably disposed inside the box (43) and located on both sides of the upper end of the rotating filter cavity (411). The filter structure (42) that moves from the driven roller one (412) is wrapped around the rotating filter cavity (411) and then comes out through the driven roller two (413), so that the rotating filter cavity (411) and the filter structure (42) form a circular filter cavity structure. The rotating filter chamber (411) is provided with circular plates (4113) at both ends, and the filter structure (42) is wound around the circular plates (4113); The continuous filtration mechanism (41) further includes a drive motor (414) and a discharge roller (415). The drive motor (414) is located on one side of the housing (43), and the discharge roller (415) is located at the discharge port of the housing (43). There are four discharge rollers (415), including a first discharge roller (4151), a second discharge roller (4152), a third discharge roller (4153), and a fourth discharge roller (4154). One end of the first discharge roller (4151) is connected to the gearbox at the output end of the drive motor (414). The ends of the second discharge roller (4152) and the third discharge roller (4153) are respectively connected to the end of the first discharge roller (4151) through a linkage gear (46). The fourth discharge roller (4154) is connected to the gearbox at the output end of the drive motor (414). The end of the discharge roller (4154) is connected to the third discharge roller (4153) via the linkage gear (46) so that when the first discharge roller (4151) rotates, it can drive the second discharge roller (4152) and the third discharge roller (4153) to rotate synchronously in opposite directions. The fourth discharge roller (4154) rotates in the same direction as the first discharge roller (4151) so as to discharge the two sets of filter structures (42) at the same time and switch the filter structure (42) on the rotating filter chamber (411) at the same time. The filter structure (42) consists of two sets, each set including a first filter structure (421) and a second filter structure (422). The first filter structure (421) is wound around the driven roller one (412), the circular plate (4113), the driven roller two (413), and the third discharge roller (4153) and the fourth discharge roller (4154). The second filter structure (422) is wound around the driven roller three (416), the support roller (418), the driven roller four (417), and the first discharge roller (4151) and the second discharge roller (4152), so that the filter structure (42) forms two layers of filter area in the rotating filter cavity (411). The second discharge roller (4152) is rotatably connected to annular limiting members at both ends. The annular limiting members are slidably disposed in the limiting grooves on the mounting brackets on both sides of the housing (43). The first discharge roller (4151) and the second discharge roller (4152) are rotatably disposed on the mounting brackets. An adjusting member (45) is provided through one end of the limiting groove. The adjusting member (45) is a screw or an electric telescopic rod. One end of the adjusting member (45) is rotatably or fixedly connected to the annular limiting member. The pressure roller (419) disposed above the driven roller four (417) inside the housing (43) descends and presses the second filter structure (422) under the action of the electric telescopic rod (47).
