Description

Technical Field

[0001] The utility model relates to a crushing and cleaning device, in particular to a crushing and cleaning device for recycling waste plastics, belonging to the technical field of plastic recycling. Background Art

[0002] With the widespread use of plastic products, the amount of waste plastics continues to increase, causing great pressure on the environment. Through recycling, crushing and cleaning, waste plastics can be converted into reusable plastic particles or raw materials, reducing dependence on virgin plastic resources, realizing resource recycling, reducing production costs, and also helping to reduce the pollution of plastic waste to the environment.

[0003] In the prior art, the utility model with application number 202323260990.6 discloses a waste plastic crushing and cleaning device. In order to solve the problem that when the plastic is transported from the cleaning box through the transmission mesh belt, the plastic is concentrated in the middle position of the transmission mesh belt, which leads to uneven thickness of the plastic on the transmission mesh belt, resulting in low subsequent air-drying efficiency, when the plastic is transported to the aggregate shell through the first transmission mesh belt, the second motor drives the threaded rod to rotate, and then drives the threaded connected sliding arm to move along the guide rod to flatten the waste plastic accumulated in the aggregate shell, ensuring that the height of the plastic accumulated in the aggregate shell is the same, and then the first motor drives the rotating drum to rotate, and the plastic is transported to the second transmission mesh belt through the material distribution space formed by the rotating drum, the partition plate and the inner wall of the aggregate shell. The flattened thickness of the plastic on the second transmission mesh belt is adjusted through the baffle, which is convenient for subsequent air drying and improves the air-drying efficiency.

[0004] Similar to the above application, there are still some deficiencies:

[0005] Due to the different densities of plastic particles, it is impossible to separate the sinking and floating particles during the waste cleaning process. Directly treating them uniformly will not only affect the quality of the particles, but also reduce the economic value of the waste.

[0035] Example 1

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, this embodiment proposes a crushing and cleaning device for recycling and processing waste plastics, including a cleaning water tank 1 and a crusher 2 installed at one end of the top of the cleaning water tank 1. The waste plastics are fed from the feed port on the top of the crusher 2 and fall into the interior of the cleaning water tank 1 after being crushed. A stirring mechanism 3 is provided inside the cleaning water tank 1 below the crusher 2. The stirring mechanism 3 stirs the plastic particles to improve the cleaning effect and controls the water flow inside the cleaning tank 1 to be transported in a direction away from the crusher 2. A discharge mechanism 4 is provided at the end of the top of the cleaning water tank 1 away from the crusher 2. The cleaned plastic particles are discharged from the discharge mechanism 4 is discharged to the outside of the device. The end of the cleaning water tank 1 is located below the discharge mechanism 4 and is provided with a guide mechanism 7 for classifying and discharging the raw materials. The discharged raw materials are separated and transported through the guide mechanism 7 to ensure the quality of the plastic particles and improve the economic value of the plastic particles. The top of one side of the interior of the cleaning water tank 1 is inclinedly provided with an upper guide plate 5 for guiding the floating material toward the discharge mechanism 4. The plastic particles floating on the liquid surface are guided and located on one side of the discharge mechanism 4. The inner bottom of the cleaning water tank 1 is provided with a sinking material conveying mechanism 6 for guiding the sinking material toward the discharge mechanism 4. The sinking material below the liquid surface will be guided to the other side of the discharge mechanism 4 for discharge.

[0037] Example 2

[0038] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0039] like Figure 1 、 Figure 2 and Figure 4 As shown, as a preferred embodiment, on the basis of the above method, the stirring mechanism 3 further includes a roller 301, a stirring rod 302, a stirring blade 303 and a pulley assembly 304. The roller 301 is rotatably installed between the two sides of the cleaning water tank 1, and the outer side of the roller 301 is evenly provided with stirring rods 302. The ends of the stirring rods 302 are all equipped with stirring blades 303. A pulley assembly 304 is provided between the end of the roller 301 and the output end of the driving motor on the crusher 2. During the operation of the driving motor on the crusher 2, the pulley assembly 304 can drive the roller 301 to rotate, control the rotation of the stirring blade 303 and the stirring rod 302, so as to drive the flow of the plastic raw material and improve the cleaning effect.

[0040] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the sinking material conveying mechanism 6 includes a lower conveyor belt 601 and a lower guide plate 602. The lower conveyor belt 601 is installed inside the cleaning water tank 1 along the length direction of the cleaning water tank 1, and a gap is left between the bottom of the lower conveyor belt 601 and the inner bottom of the cleaning water tank 1. A lower guide plate 602 is inclined on the side of the cleaning water tank 1 away from the upper guide plate 5. The bottom of the lower guide plate 602 is in contact with the top of the lower conveyor belt 601. The upper guide plate 5 and the lower guide plate 602 are respectively inclined toward the two sides of the discharge mechanism 4, and the bottom of the upper guide plate 5 is in contact with the top of the lower guide plate 602. The plastic particles sunk below the liquid surface will fall on the top of the lower conveyor belt 601, and then move toward the discharge mechanism 4 through the lower conveyor belt 601. In the process of moving the plastic particles, the sinking material is moved toward the side away from the floating material through the guiding effect of the lower guide plate 602, so as to separate the floating material and the sinking material.

[0041] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, the discharge mechanism 4 further includes an upper conveyor belt 401, a middle partition 402 and an L-shaped salvage plate 403. The upper conveyor belt 401 is obliquely installed at the end of the cleaning water tank 1, the bottom end of the upper conveyor belt 401 is below the liquid level, and the top end of the upper conveyor belt 401 is above the liquid level. L-shaped salvage plates 403 are evenly installed on the outside of the upper conveyor belt 401, and a middle partition 402 is provided at the middle position of the outside of the upper conveyor belt 401. The upper guide plate 5 and the lower guide plate 602 are respectively facing the two sides of the middle partition 402. When the plastic particles are discharged, the upper conveyor belt 401 drives the L-shaped salvage plate 403 to rotate, and the middle partition 402 will separate the L-shaped salvage plate 403. Therefore, the two sides of the L-shaped salvage plate 403 respectively salvage the floating material and the sinking material, transport them upward, and fall into the guide mechanism 7 for discharge.

[0042] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, an arc-shaped collecting plate 603 is fixed to the bottom end of the upper conveyor belt 401, and the arc-shaped collecting plate 603 is attached to the end of the lower conveyor belt 601. The inner side of the arc-shaped collecting plate 603 is attached to the bottom end of the L-shaped salvage plate 403. The arc-shaped collecting plate 603 can collect the sinking materials discharged from the lower conveyor belt 601, so that the L-shaped salvage plate 403 can completely salvage the sinking materials.

[0043] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the surfaces of the upper conveyor belt 401, the middle partition 402 and the lower conveyor belt 601 are all provided with leakage holes, and the diameter of the leakage holes is smaller than the diameter of the plastic particles. The leakage holes on the lower conveyor belt 601 can conveniently intercept only the sediment, and the cleaned sludge will fall to the bottom of the cleaning water tank. The leakage holes on the upper conveyor belt 401 and the middle partition 402 can facilitate the discharge of water stains in the plastic particles.

[0044] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, the guiding mechanism 7 further includes a support plate 701 and a Y-shaped partition plate 702, the support plate 701 is horizontally fixed at the end of the cleaning water tank 1, and the support plate 701 is located below the top of the upper conveyor belt 401, and a Y-shaped partition plate 702 is fixed at the middle position of the top of the support plate 701, and the particles falling onto the support plate 701 are separated by the Y-shaped partition plate 702 and discharged from both sides.

[0045] Example 3

[0046] The following further describes the solutions in Example 1 and Example 2 in conjunction with specific working methods, as described below:

[0047] Waste plastics are fed from the top feed port of the crusher 2 and fall into the interior of the cleaning water tank 1 after being crushed. During the operation of the driving motor on the crusher 2, the pulley assembly 304 can drive the roller 301 to rotate, control the rotation of the stirring blade 303 and the stirring rod 302, so as to drive the flow of the plastic raw materials and improve the cleaning effect. At the same time, the raw materials on the top of the cleaning tank 1 are slowly transported in the direction away from the crusher 2. The plastic particles floating on the liquid surface are transported to the side of the upper conveyor belt 401 through the upper guide plate 5 and sink below the liquid surface. The plastic particles will fall on the top of the lower conveyor belt 601, and then be transported to the other side of the upper conveyor belt 401 through the lower conveyor belt 601. The upper conveyor belt 401 drives the L-shaped salvage plate 403 to rotate, and the middle partition plate 402 will separate the L-shaped salvage plate 403. Therefore, the two sides of the L-shaped salvage plate 403 will salvage the floating material and the sinking material respectively, transport them upward, and fall onto the top of the supporting plate 701. Since the particles falling on the supporting plate 701 are separated by the Y-shaped partition plate 702, the plastic particles are discharged from both sides.

[0048] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
