Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment, in particular to cleaning equipment for pre-processing plastic particles. Background Art

[0002] When recycling plastics, they are first crushed, and then the plastic particles formed after crushing are cleaned, mainly by rinsing in a water tank. Common cleaning equipment mainly includes a water tank, a conveying screw arranged on the bottom wall of the water tank, and a conveyor arranged on the top of the water tank. When in use, the plastic particles are poured into the water tank, and the buoyancy is used to distinguish the two different types of plastics. The conveyor pushes the floating plastics, and finally collects and salvages them separately. The sunken plastic particles move under the pushing action of the conveying screw and fall from the discharge port. This type of cleaning equipment has certain shortcomings: first, the plastic particles are generally transported to the water tank by a conveyor, and the two different plastic particles are mixed with each other, or because of the viscosity of the plastic particles themselves, or because of the gravity of the plastic particles, some floating plastics cannot float after entering the water, and the distinction effect is poor; secondly, the impurities falling from the plastic particles will settle in the water tank, contact with the plastic particles that sink at the bottom of the water tank, and then attach to the plastic particles for a second time, and the cleaning effect is not good.

[0003] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a cleaning device for pre-treatment of plastic particles.

[0035] Example 1: Please refer to Figure 1 - Figure 3 A cleaning device for pre-treatment of plastic particles, comprising a water tank 1, a cleaning chamber 2 and an exchange chamber 3 are respectively arranged on both sides of the water tank 1, a pumping assembly 4 is installed on the outer wall of the water tank 1, and a fixed frame 5, a screen basket 6, a vertical drive assembly 7, a horizontal drive assembly 8 and a material discharge assembly 9 are arranged above the cleaning chamber 2;

[0036] The pumping assembly 4 is connected between the cleaning chamber 2 and the exchange chamber 3, and is used to drive the water in the cleaning chamber 2 and the exchange chamber 3 to circulate;

[0037] The sieve basket 6 is installed inside the fixed frame 5, and the sieve basket 6 is used to place plastic particles. The vertical drive assembly 7 and the horizontal drive assembly 8 are both installed on the fixed frame 5. The vertical drive assembly 7 is used to drive the sieve basket 6 to move vertically, and the horizontal drive assembly 8 is used to drive the sieve basket 6 to move reciprocatingly horizontally.

[0038] The unloading assembly 9 is installed on the screen basket 6, and the unloading assembly 9 is used to unload the plastic in the screen basket 6;

[0039] When cleaning the plastic particles, the plastic particles are poured into the screen basket 6, and the vertical drive component 7 drives the screen basket 6 to move down into the cleaning chamber 2. The water separates the two plastic particles through buoyancy, and at the same time, the pumping component 4 operates to force the water in the cleaning chamber 2 to flow, thereby removing impurities in the plastic particles and driving the floating plastic particles to move. Then, the vertical drive component 7 operates again to force the screen basket 6 to move up. When the screen basket 6 and the internal plastic particles are separated from the cleaning chamber, the horizontal drive component 8 operates to drive the screen basket 6 and the internal plastic particles to move back and forth horizontally, forcing the adhered floating plastic particles and the sinking plastic particles to separate from each other. Finally, the vertical drive component 7 operates again to force the screen basket 6 to move down to the cleaning chamber 2 again to continue to remove impurities and separate plastics. When the cleaning work is completed, the unloading component 9 operates to unload the plastic particles in the screen basket 6.

[0040] Among them, a partition is fixed on the inner wall of the water tank 1, and the partition divides the inner cavity of the water tank 1 into a cleaning cavity 2 and an exchange cavity 3. In actual use, the water level in the cleaning cavity 2 is higher than the top edge of the partition, and the water level inside the exchange cavity 3 is lower than the top edge of the partition. The bottom of the cleaning cavity 2 and the bottom of the exchange cavity 3 are both set to be funnel-shaped, and a sewage pipe is installed at the bottom, which is used to discharge impurities deposited at the bottom of the cavity. The screen basket 6 is provided with fine and uniform through holes, and the diameter of the through holes is smaller than the diameter of the plastic particles;

[0041] When in use, start the pumping assembly 4. When the pumping assembly 4 is running, the water in the cleaning chamber 2 flows into the exchange chamber 3, and then flows back from the exchange chamber 3 to the cleaning chamber 2, so that the water body flows dynamically. Then, the mixed plastic particles are poured into the screen basket 6, and then the vertical drive assembly 7 is started. The vertical drive assembly 7 drives the screen basket 6 to move down to the inside of the cleaning chamber 2. When the screen basket 6 is submerged below the water level, the buoyancy of the water body causes the floating plastic particles to float on the water surface and are washed away by the flowing water body, and the remaining plastic particles sink in the water body. At this time, the water flow cleans the impurities attached to the plastic particles and transfers the impurities to the water body, but at this time, some impurities are still not cleaned up, and at the same time, some The floating plastic particles are mixed with the submerged plastic particles in the water; then the vertical drive assembly 7 is started again, and the vertical drive assembly 7 drives the screen basket 6 to move upward to leave the cleaning chamber 2, and then the transverse drive assembly 8 is started, and the transverse drive assembly 8 drives the screen basket 6 to move back and forth laterally, so that the plastic particles inside the screen basket 6 move back and forth. At this time, the plastic particles rub and collide with each other, which can separate the adhered plastic particles and clean the attached impurities. Then the vertical drive assembly 7 is started again, and the screen basket 6 is moved to the cleaning chamber 2 again. Similarly, impurities are removed and plastics are separated again under the action of water flow. The above operations are repeated many times to complete the thorough separation and cleaning of the two types of plastics.

[0042] By providing a cleaning chamber 2, an exchange chamber 3 and a pumping assembly 4, water in the cleaning tank can flow. At the same time, by providing a fixed frame 5, a screen basket 6, a vertical drive assembly 7 and a horizontal drive assembly 8, the vertical drive assembly 7 drives the screen basket 6 to move vertically, and the horizontal drive assembly 8 drives the screen basket 6 to move back and forth horizontally, which is beneficial to repeatedly washing the plastic particles in the screen basket 6. It can not only efficiently separate two different types of plastic particles and improve the recovery quality of plastic particles, but also effectively clean impurities on the plastic to avoid secondary attachment of impurities. Compared with the prior art, the cleaning effect is better.

[0043] Example 2: See Figure 2 and Figure 3 , which is different from the above embodiment, the pumping assembly 4 includes a water pump 41 fixed to the outer wall of the water tank 1, the input end of the water pump 41 extends into the exchange chamber 3, and a water pipe 42 is fixed to the output end of the water pump 41, one end of the water pipe 42 extends into the cleaning chamber 2, and one end of the water pipe 42 located inside the cleaning chamber 2 is fixedly connected to a flow equalizing pipe 43;

[0044] The flow balancing pipe 43 is a horizontal pipe, and its length is the same as the width of the cleaning chamber 2. The flow balancing pipe 43 is provided with evenly distributed water outlet holes for evenly discharging water into the cleaning chamber 2 to ensure that the water flow is more even and gentle.

[0045] When in use, start the water pump 41, which pumps the water out of the exchange chamber 3 and discharges it into the cleaning chamber 2 through the water pipe 42 and the flow equalizing pipe 43, thereby realizing the circulation of water. The flowing water makes it easier to remove impurities on the plastic particles, and can also drive the plastic particles floating on the water surface of the cleaning chamber 2 to move for subsequent collection.

[0046] Example 3, see Figure 4 , which is different from the above-mentioned embodiment, a plurality of legs 51 are fixed to the edge of the fixed frame 5, and the legs 51 are fixedly connected to the outer wall of the water tank 1, and the vertical drive assembly 7 includes a movable frame 71, and the screen basket 6 is installed on the inner side of the movable frame 71, and a plurality of vertical racks 72 are fixed to the edge of the movable frame 71, and the vertical racks 72 are vertically slidably connected to the fixed frame 5, and the vertical drive assembly 7 also includes a first motor 73, and the first motor 73 is fixed to the outer wall of the fixed frame 5, and a rotating shaft 74 is fixedly connected to the output shaft of the first motor 73, and the rotating shaft 74 is installed on the frame through a first bearing seat 75, and a first gear 76 is fixed to the rotating shaft 74, and the first gear 76 is meshed with the vertical rack 72;

[0047] The movable frame 71 and the fixed frame 5 are preferably set to a square shape, and the side length of the fixed frame 5 is greater than the side length of the movable frame 71, so that there is no obstacle in the area above the screen basket 6, which is convenient for loading. The vertical racks 72 are preferably set to four, two of which are a group, and the first motor 73, the rotating shaft 74, the first bearing seat 75 and the first gear 76 are also set to two groups, and are matched with the two groups of vertical racks 72 respectively;

[0048] When in use, start the first motor 73, the first motor 73 drives the rotating shaft 74 to rotate, driving the first gear 76 to rotate. When the first gear 76 rotates, it drives the vertical rack 72 to move vertically, thereby driving the movable frame 71 and the internal screen basket 6 to move vertically, which is beneficial to drive the screen basket 6 to move back and forth into the cleaning chamber 2, so as to separate and wash the plastic particles in the screen basket 6.

[0049] Example 4, see Figure 5 and Figure 6 , which is different from the above embodiment, both sides of the screen basket 6 are fixedly connected with guide rods 61, the guide rods 61 are movably plugged with the movable frame 71, the ends of the guide rods 61 are fixedly connected with end heads 62, a spring 63 is fixedly connected between the end heads 62 and the movable frame 71, the spring 63 is sleeved on the outside of the guide rods 61, a through slot 64 is provided on the side wall of the movable frame 71, the transverse drive assembly 8 includes a second motor 81 fixed on the fixed frame 5, the output shaft of the second motor 81 is fixedly connected with a second gear 82, the transverse drive assembly 8 also includes an angle steel 83 and a vertical shaft 84, the vertical shaft 84 passes through the movable frame The frame 71 is rotatably connected to the movable frame 71, a disc 85 is fixed to the bottom end of the vertical shaft 84, a push rod 86 is provided on the bottom wall of the disc 85, one end of the push rod 86 passes through the through slot 64 and is hinged to the screen basket 6, and the other end of the push rod 86 is rotatably connected to the bottom edge of the disc 85, a driven bevel gear 87 is fixed to the top of the vertical shaft 84, the angle steel 83 is fixed to the edge of the movable frame 71, a horizontal shaft 88 is rotatably connected to the angle steel 83, a third gear 89 and a driving bevel gear 80 are respectively fixed to both ends of the horizontal shaft 88, the driving bevel gear 80 is meshed with the driven bevel gear 87, and the third gear 89 is located directly below the second gear 82;

[0050] Wherein, two guide rods 61 are respectively arranged on both sides of the screen basket 6. In the initial state, the springs 63 on each guide rod 61 are at an initial length, and there is a gap between the outer wall of the screen basket 6 and the inner wall of the movable frame 71;

[0051] When in use, the vertical drive assembly 7 operates, forcing the movable frame 71 to move up, so that the third gear 89 on the movable frame 71 just moves up to mesh with the second gear 82. At this time, the screen basket 6 is suspended above the cleaning chamber 2, and the second motor 81 is started. The second motor 81 operates to drive the second gear 82 to rotate, and the second gear 82 rotates to drive the third gear 89 to rotate. When the third gear 89 rotates, it drives the horizontal shaft 88 and the active bevel gear 80 to rotate. When the active bevel gear 80 rotates, it drives the driven bevel gear 87 to rotate. When the driven bevel gear 87 rotates, it drives the vertical shaft 84 and the bottom disc 85 to rotate. When the disc 85 rotates, it drives the bottom push rod 86 to reciprocate, thereby pushing the screen basket 6 to reciprocate along the direction of the guide rod 61. When the screen basket 6 moves, it drives the plastic particles inside to reciprocate, so that the plastic particles collide and rub against each other, which can better remove impurities and separate two different plastic particles adhering to each other.

[0052] By setting up the vertical drive assembly 7, when the screen basket 6 moves up and close to the fixed frame 5, the second motor 81 is used to drive the push rod 86 on one side of the screen basket 6 to reciprocate, thereby pushing the screen basket 6 to move back and forth, which is beneficial to driving the plastic particles inside the screen basket 6 to reciprocate. The friction and impact between the plastic particles can better clean impurities and improve the cleaning effect. It can also separate the adhered particles, improve the subsequent screening effect, and thus improve the quality of plastic recycling.

[0053] Example 5, see Figure 1 , Figure 6 and Figure 7 , which is different from the above embodiment, the screen basket 6 includes a basket wall 65 and two symmetrically arranged gate plates 66 arranged at the bottom of the basket wall 65, a base shaft 67 is fixed to one side edge of the gate plate 66, the base shaft 67 is rotatably connected to the basket wall 65, one end of the base shaft 67 is fixedly connected to a bar frame 68, and the blanking assembly 9 includes a vertical cylinder 91 fixed to the basket wall 65, the output end of the vertical cylinder 91 faces downward and is fixed with a crossbeam 92, both ends of the crossbeam 92 are fixed with latches 93, and the latches 93 are movably plugged into the bar frame 68;

[0054] Among them, the strip frame 68 is provided with a strip hole, and the two latches 93 at both ends of the cross beam 92 are respectively inserted into the strip holes in the two strip frames 68. When in use, the vertical cylinder 91 is started, and the vertical cylinder 91 extends to push the cross beam 92 downward. When the cross beam 92 moves downward, the latches 93 at both ends push the strip frame 68, so that the strip frame 68 swings. When the strip frame 68 swings, it drives the base shaft 67 to rotate, and then drives the gate plate 66 to rotate. At this time, after the two gate plates 66 rotate at the same time, the plastic particles inside the screen basket 6 fall to the bottom along the gate plates 66, thereby realizing material unloading. After the unloading is completed, the vertical cylinder 91 contracts to drive the gate plate 66 to reset;

[0055] By providing the unloading assembly 9 and driving the gate plate 66 to open and close through the vertical cylinder 91, it is beneficial to unload the plastic particles after cleaning the plastic particles, and the unloading speed is fast and the efficiency is high.

[0056] Example 6, see Figure 8 and Fig. 9 , which is different from the above embodiment, a horizontal conveyor 10 is further provided above the cleaning chamber 2, and transverse slides 11 are provided on both sides of the horizontal conveyor 10, and the transverse slides 11 are fixed on the top of the water tank 1, and a slide seat 12 is provided on the transverse slide 11, and the slide seat 12 is fixedly connected to the side wall of the horizontal conveyor 10;

[0057] Among them, the transverse slide 11 is set as an electric slide. In the initial state, the horizontal conveyor 10 is located at the top edge of the water tank 1, which will not affect the vertical movement of the screen basket 6. When in use, before unloading the plastic particles, the transverse slide 11 is started first. When the transverse slide 11 is running, it drives the slide 12 to move, and the slide 12 drives the horizontal conveyor 10 to move, so that the horizontal conveyor 10 moves to the bottom of the screen basket 6. When unloading, the plastic particles dropped just fall on the horizontal conveyor 10, and the plastic particles are transported to the next station through the horizontal conveyor 10;

[0058] By providing a movable horizontal conveyor 10, it is convenient to receive the unloaded plastic and automatically transfer the plastic to the next station, thus saving the transfer time of the cleaned plastic and improving the plastic processing efficiency.

[0059] Embodiment 7, see Figure 8 and Fig. 9 , which is different from the above-mentioned embodiment, main pulleys 13 are fixed at both ends of the driving shaft of the horizontal conveyor 10, brackets 14 are fixed on both sides of the horizontal conveyor 10, a transmission shaft 15 is provided at the top of the bracket 14, the transmission shaft 15 is installed on the bracket 14 through a second bearing seat 16, and auxiliary pulleys 17 and cams 18 are fixed at both ends of the transmission shaft 15, and the auxiliary pulley 17 is connected to the main pulley 13 through a transmission belt 19;

[0060] Among them, the horizontal conveyor 10 and its transmission shaft 15 are both prior art and will not be described in detail. When the horizontal conveyor 10 is running, the drive shaft rotates. When unloading, the vertical drive assembly 7 is used to drive the movable frame 71 and the screen basket 6 to move vertically, so that the third gear 89 on the movable frame 71 is separated from the second gear 82 on the fixed frame 5. The horizontal conveyor 10 moves to the bottom of the screen basket 6 under the action of the transverse slide 11. At the same time, the cam 18 on the horizontal conveyor 10 just moves to the side wall surface of the screen basket 6. During the unloading process, the horizontal conveyor 10 operates to carry out plastic The transfer of particles drives the main pulley 13 on the driving shaft to rotate at the same time. When the main pulley 13 rotates, it drives the secondary pulley 17 to rotate through the transmission belt 19, and then drives the transmission shaft 15 to rotate. When the transmission shaft 15 rotates, it drives the cam 18 to rotate. When the cam 18 rotates, it pushes the screen basket 6 to move. When the screen basket 6 moves, it drives the guide rod 61 to move, so that the spring 63 is deformed. Under the elastic force of the spring 63, the screen basket 6 is driven to reset. The screen basket 6 is constantly hit and reset by the cam 18, thereby forming a vibration effect, making it easier for the plastic particles adhering to the screen basket 6 to fall off;

[0061] By arranging a cam 18 on the horizontal conveyor 10, the cam 18 is driven to rotate when the horizontal conveyor 10 is running. After the cam 18 pushes the screen basket 6, the screen basket 6 is reset under the action of the spring 63, thereby achieving a vibration effect, which is conducive to making the plastic particles adhered to the screen basket 6 easier to fall off during unloading, thereby improving the unloading effect of the plastic particles and avoiding the residue of plastic particles.

[0063] Among them, the structure of the screen machine 20 is the existing technology, and the width of the screen machine 20 matches the width of the cleaning chamber 2. When in use, the plastic particles floating in the cleaning chamber 2 are washed toward the screen machine 20 by the water flow. After the screen machine 20 is in operation, such plastic particles are salvaged and collected, which is convenient for unified processing in the next step, and at the same time, it also prevents such plastic particles from entering the exchange chamber 3 and eventually clogging the pumping component 4.
