Description

Technical Field

[0001] This utility model relates to the field of source blocking technology for fibrous microplastics, specifically a device for releasing fibrous microplastics during the washing process of a drum washing machine. Background Technology

[0002] Fibrous microplastics, a form of microplastics, refer to fibrous plastic fragments or particles with a diameter of less than 5 millimeters. They are widely distributed in the environment and may pose a threat to both ecosystems and human health.

[0003] A microplastic release device is used to simulate or study the release process of microplastics from various materials. This device primarily simulates the mechanical friction, water erosion, and chemical reactions experienced by microplastics in natural environments or during actual use, thereby promoting the release of microplastics from materials. For example, a device simulating a washing process typically includes an agitator similar to a washing machine. This agitation causes fibrous materials such as clothing to rub and collide with each other in an aqueous solution, causing the microplastics to detach and be released into the water.

[0004] These shed fibers are discharged into the environment with wastewater, posing a potential threat to the ecological environment. Therefore, workers often use filtration devices to intercept fibers in laundry wastewater and prevent them from being discharged into the environment.

[0005] However, the filter plates of current microplastic fiber release devices have a cumbersome installation process. When staff need to clean or replace the filter plates, quick disassembly and installation are not possible, which greatly reduces work efficiency and adds many inconveniences to daily maintenance.

[0006] Therefore, there is an urgent need for a device to release microplastics from fibers during the washing process of a drum washing machine to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a fiber microplastic release device for a drum washing machine during the washing process, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fiber microplastic release device for a drum washing machine during the washing process, comprising a housing, a mounting slot, and a quick-release mechanism; a plurality of mounting slots are installed inside the housing, and the quick-release mechanism is installed at the bottom of the mounting slots;

[0009] The quick-release mechanism includes a base, a rotating shaft, a gear, multiple racks, and multiple connecting rods. The base is installed below the mounting slot, the rotating shaft is installed inside the base, the gear is rotatably connected to the outer periphery of the rotating shaft, the racks are slidably installed inside the base and mesh with the gear, and the connecting rods are installed on the racks and located outside the base.

[0010] Preferably, the base has fixing grooves on both sides, and the mounting slot has fixing grooves on both sides at the end near the base.

[0011] Preferably, a blocking block is fixedly connected to the end of the rack away from the connecting rod.

[0012] Preferably, the base is provided with a placement groove, and a sealing gasket is provided at the position where the placement groove contacts the mounting slot.

[0013] Preferably, the water inlet end of the outer casing is equipped with a water inlet, and the water outlet end of the outer casing is equipped with a water outlet.

[0014] Preferably, a filter material is installed inside the placement trough. The filter material includes a first filter plate, a second filter plate, and a third filter plate. The first filter plate is installed inside the placement trough near the water inlet, the third filter plate is installed inside the placement trough near the water outlet, and the second filter plate is installed inside the placement trough located between the first filter plate and the third filter plate.

[0015] Preferably, an inclined plate is installed on the side of the mounting slot near the water inlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model connects the outer shell and the base together through the cooperation of the connecting rod and the fixing groove of the quick-release mechanism. When the worker grasps the connecting rod and pulls the rack out of the base, the rack pulls out and drives the gear to start rotating around the pivot, which in turn drives another rack to be pulled out of the base, and the connecting rod installed on it is pulled out together. At this time, the two connecting rods used to connect the base and the outer shell are disengaged from the fixing groove, and the base and the outer shell are separated, realizing the quick disassembly of the base and the outer shell and improving the work efficiency of the worker.

[0025] 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.

[0026] Please see Figures 1 to 6 The present invention provides an embodiment of a fiber microplastic release device for a drum washing machine during the washing process, comprising a housing 1, a mounting slot 2, and a quick-release mechanism 3; the housing 1 has multiple mounting slots 2 installed inside, the mounting slots 2 being used to insert a first filter plate 91, a second filter plate 92, and a third filter plate 93. The first filter plate 91, the second filter plate 92, and the third filter plate 93 are fixed in the mounting slots 2, so that the first filter plate 91, the second filter plate 92, and the third filter plate 93 will not move due to the impact of water flow.

[0027] A quick-release mechanism 3 is installed at the bottom of the mounting slot 2. The quick-release mechanism 3 is used to help the staff quickly separate the base 31 and the outer shell 1, so as to facilitate the staff to replace the filter material 9 and improve the staff's work efficiency.

[0028] The quick-release mechanism 3 includes a base 31, a rotating shaft 32, a gear 33, multiple racks 34, multiple fixing slots 35, and multiple connecting rods 36. Each rack 34, fixing slot 35, and connecting rod 36 has two units. The base 31 has fixing slots 35 on both sides, and the mounting slot 2 has fixing slots 35 on both sides near the end of the base 31. The connecting rods 36 can be inserted into the fixing slots 35 on the base 31 and the mounting slot 2, connecting the base 31 and the fixing slots 35.

[0029] The base 31 is located below the mounting slot 2. The rotating shaft 32 is installed inside the base 31. The gear 33 is rotatably installed on the outer periphery of the rotating shaft 32. The rack 34 is slidably installed inside the base 31 and meshes with the gear 33. The connecting rod 36 is installed on the rack 34 and located outside the base 31. The fixing groove 35 is installed on the base 31 and the mounting slot 2 on the side near the connecting rod 36.

[0030] A blocking block 37 is fixedly connected to the end of the rack 34 away from the connecting rod 36. The blocking block 37 can prevent the worker from pulling the rack 34 completely out of the base 31 when pulling the rack 34 through the connecting rod 36.

[0031] When the quick-release mechanism 3 and the mounting slot 2 are closed, the two ends of the connecting rod 36 mounted on the rack 34 will be inserted into the fixing groove 35 on the side of the base 31 and the fixing groove 35 on the side of the mounting slot 2, respectively. At this time, the base 31 and the mounting slot 2 are firmly connected by the connecting rod 36, and the two cannot be easily separated.

[0032] When the operator needs to separate the base 31 from the mounting slot 2, they simply grasp one end of the connecting rod 36 and pull the rack 34 outward through the connecting rod 36, thus pulling the connecting rod 36 out of the fixing groove 35 on the side of the base 31 and the mounting slot 2. Since both racks 34 mesh with the gear 33, and the gear 33 is rotatably connected to the outer circumference of the rotating shaft 32, when the operator pulls one rack 34, the pulling action of the rack 34 will cause the gear 33 to rotate around the rotating shaft 32. The rotation of the gear 33 will further cause the other rack 34 to be pulled out of the base 31 simultaneously, thus allowing the connecting rods 36 on both sides to be pulled out of the fixing groove 35 on the side of the base 31 and the mounting slot 2 at the same time, ultimately achieving the purpose of quick disassembly.

[0033] The quick-release mechanism 3 not only enables quick disassembly of the base 31 and the mounting slot 2, but also allows for rapid installation. When an operator wants to install the base 31 into the mounting slot 2, they first completely close the base 31 and mounting slot 2. After the base 31 and mounting slot 2 are completely closed, the operator pushes either connecting rod 36, causing the rack 34 to enter the base 31. Since both racks 34 mesh with gears 33, and gears 33 are rotatably connected to the outer circumference of the rotating shaft 32, when the operator pushes one rack 34, the entry of the rack 34 causes the gear 33 to rotate around the rotating shaft 32. The rotation of the gear 33 further drives the other rack 34 to simultaneously enter the base 31, allowing the connecting rods 36 on both sides to be simultaneously inserted into the fixing slots 35 on the sides of the base 31 and mounting slot 2, thus achieving rapid installation.

[0034] Specifically, a placement groove 4 is installed on the base 31. The placement groove 4 cooperates with the base 31 to limit the filter material 9. When the operator uses the quick-release mechanism 3 to separate the base 31 from the outer casing 1, the filter material 9 will be limited inside the placement groove 4 due to the limiting function of the placement groove 4 and the base 31, and will not fall out of the placement groove 4, making it convenient for the operator to replace and install the filter material 9. A sealing gasket 5 is installed at the contact position between the placement groove 4 and the mounting slot 2. When the sealing gasket 5 is subjected to pressure from the placement groove 4 and the mounting slot 2, it will undergo elastic deformation. This deformation allows it to better fit the surface of the connecting parts, thereby maintaining the sealing effect.

[0035] Specifically, the inlet end of the outer casing 1 is equipped with an inlet 7, and the outlet end of the outer casing 1 is equipped with an outlet 8. The function of the inlet 7 and the outlet 8 is to determine the flow direction of the water to be filtered, ensuring that the water to be filtered first flows from the first filter plate 91 to the second filter plate 92, and then from the second filter plate 92 to the third filter plate 93, thereby achieving the purpose of filtering the water to be filtered.

[0036] Specifically, the placement tank 4 is equipped with filter material 9, which includes a first filter plate 91, a second filter plate 92 and a third filter plate 93. The first filter plate 91 is installed inside the placement tank 4 near the water inlet 7, the third filter plate 93 is installed inside the placement tank 4 near the water outlet 8, and the second filter plate 92 is installed inside the placement tank 4 located between the first filter plate 91 and the third filter plate 93.

[0037] The pore sizes of the first filter plate 91, the second filter plate 92, and the third filter plate 93 are as follows: the pore size of the first filter plate 91 is larger than that of the second filter plate 92, and the pore size of the second filter plate 92 is larger than that of the third filter plate 93. The first filter plate 91 first intercepts larger particles of impurities, preventing these large particles from entering subsequent filtration stages and causing blockage or damage to the second and third filter plates 93. It also reduces the filtration pressure on the subsequent second and third filter plates 92 and 93. Next, the second filter plate 92 intercepts medium-sized impurities, further improving the filtration effect. Finally, the third filter plate 93 intercepts even smaller particles, achieving finer filtration. The main purpose of the third filter plate 93 is to filter out fibrous microplastics from the liquid being filtered, preventing fibers from being released into the environment.

[0038] When the operator separates the base 31 from the outer casing 1 and removes the first filter plate 91, the second filter plate 92, or the third filter plate 93, the impurities intercepted on the surface of the first filter plate 91, the second filter plate 92, or the third filter plate 93 will detach from their surfaces and fall into the interior of the outer casing 1, making it impossible for the operator to completely clean the impurities. Specifically, an inclined plate 6 is installed on the side of the mounting slot 2 near the water inlet 7. After the inclined plate 6 is installed on the side of the mounting slot 2 near the water inlet 7, the impurities detached from the surface of the first filter plate 91, the second filter plate 92, or the third filter plate 93 will fall onto the inclined plate 6. After the impurities fall onto the inclined plate 6, because the inclined angle of the inclined plate 6 is to guide from the inside of the outer casing 1 to the outside of the outer casing 1, the impurities will slide on the surface of the inclined plate 6 and then move from the inside of the outer casing 1 to the outside of the outer casing 1.

[0039] Working principle:

[0040] When too much fiber plastic accumulates on the first filter plate 91, the second filter plate 92, or the third filter plate 93, causing obstruction of the water flow, the staff should clean the filter material 9 inside the mounting slot 2.

[0041] The operator grasps either end of the rack 34 and pulls it outward to remove the connecting rod 36 from the fixing groove 35 on the side of the base 31 and the mounting slot 2. Since both racks 34 mesh with gears 33, and the gears 33 are rotatably connected to the outer circumference of the rotating shaft 32, when the operator pulls one rack 34, the removal of that rack 34 causes the gear 33 to rotate around the rotating shaft 32. This rotation of the gear 33 then causes the other rack 34 to be simultaneously removed from the base 31, allowing the connecting rods 36 on both sides to be removed simultaneously from the fixing groove 35 on the side of the base 31 and the mounting slot 2.

[0042] After the staff completely separates the base 31 from the slot 2, they take the filter material 9 out of the placement slot 4 and clean the impurities on the surface of the filter material 9.

[0043] After the staff has cleaned the filter material 9, they first completely close the base 31 and the mounting slot 2. Once the base 31 and mounting slot 2 are fully closed, the staff pushes one of the racks 34, causing it to enter the base 31. Since both racks 34 mesh with gears 33, and gears 33 are rotatably connected to the outer circumference of the rotating shaft 32, pushing one rack 34 causes it to enter, rotating the gears 33 around the rotating shaft 32. This rotation of the gears 33 then drives the other rack 34 to simultaneously enter the base 31, allowing the connecting rods 36 on both sides to be simultaneously inserted into the fixing slots 35 on the sides of the base 31 and mounting slot 2, thus installing the filter material 9 back into the mounting slot 2.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
