[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7, a processing device for recycling and reusing foam plastics, including a recycling chamber 1, with a blanking bin 106 on the top of the recycling chamber 1, and also including: two partitions, which are vertically arranged in the recycling chamber 1, and the two partitions divide the space in the recycling chamber 1 into a processing bin 101, a partition chamber 102, and an equipment chamber 103. The processing bin 101 is located below the blanking bin 106, and the processing bin 101 is connected to the blanking bin 106; six kneading plates 4 are all slidably connected in the processing bin 101, and the kneading plates 4 are arranged at equal intervals from top to bottom, and two adjacent kneading plates 4 form a group. This embodiment adopts three groups, and the gap between each group of kneading plates 4 is gradually reduced. The gap between the group of kneading plates 4 near the blanking bin 106 is the largest, and the gap near the bottom water storage chamber 104 is the smallest. The largest gap should be enough to accommodate the foam plastic put into the recycling chamber 1, and the smallest gap should be slightly larger than the diameter of the spherical foam particles. The two ends of the kneading plate 4 respectively pass through the two partitions. The plates are respectively located in the compartment 102 and the equipment chamber 103. Through the lateral movement of the kneading plate 4, the foam plastics in the two kneading plates 4 can be kneaded to split the foam plastics into small particles; multiple telescopic cylinders 2 are fixedly connected in the equipment chamber 103, and the telescopic ends of the telescopic cylinders 2 are fixedly connected to the kneading plates 4. A water storage chamber 104 is provided at the bottom of the recovery chamber 1 for receiving the granular foam plastics falling from the processing bin 101, and the water storage chamber 104 is connected to a water inlet pipe. A centrifugal pump 8 is fixedly connected to the recovery chamber 1, and a cleaning chamber 7 is arranged next to the recovery chamber 1. The centrifugal pump 8 is used to transport the foam plastics in the water storage chamber 104 to the cleaning chamber 7. A motor 701 is fixedly connected to the cleaning chamber 7, and a paddle 702 is rotatably connected in the cleaning chamber 7. The paddle 702 is fixedly connected to the output end of the motor 701. A filter screen 703 is provided above the paddle 702 in the cleaning chamber 7, and a discharge pipe is connected to the cleaning chamber 7 above the filter screen 703.

[0020] like Figure 2 、 Figure 5 As shown, a guide plate 105 is provided in the recovery chamber 1, and the guide plate 105 can guide the foam plastic fragments above to between the kneading plates 4 below, so as to facilitate the kneading plates 4 to process the foam plastic.

[0021] When the device is in use, the water inlet pipe is connected to the external water supply pipe to allow water to enter the water storage chamber 104, and the motor 701 and the centrifugal pump 8 are started. Then, the foam plastic to be recycled is dropped into the recycling chamber 1 through the nozzle above the drop bin 106. At this time, the foam plastic will accumulate in the recycling chamber 1, and some of the foam plastic will fall between the top group of kneading plates 4. At this time, the telescopic cylinder 2 is started. When the telescopic cylinder 2 is started, the two groups of kneading plates 4 move in opposite directions, such as one moves to the left and the other moves to the right. In this way, the foam plastic located between the two kneading plates 4 can be squeezed by moving in opposite directions. The spherical foam plastic particles are kneaded and separated to fall off from the large foam plastic blocks. Then, under the action of the guide plate 105, these foam plastics enter the position with a smaller distance between the two lower kneading plates 4 for further processing. Since the gap between the kneading plates 4 of the lowermost group is slightly larger than the diameter of the spherical foam plastic particles, the largest foam plastic particles passing through the lowermost group should be complete spherical foam plastic particles, and the rest are some hemispherical particles and residues. Finally, the foam plastic particles fall into the water storage chamber 104 at the lowermost group. Since the motor 701 and the centrifugal pump 8 have been started before, and there is water in the water storage chamber 104 all the time, and the foam plastic will float on the water, the centrifugal pump 8 will now suck the foam plastic floating on the water surface into the cleaning chamber 7 together with the water, and then the water will continuously fill the space in the cleaning chamber 7, wherein the water level in the water storage chamber 104 should always be within the area of the liquid inlet of the centrifugal pump 8 to prevent the foam plastic from entering the cleaning chamber 7, and the start of the motor 701 will cause the paddle 702 to rotate continuously, thereby continuously stirring the liquid in the cleaning chamber 7, so that the foam plastic floating on the water surface is continuously in contact with the water, and then cleaning is carried out, and at the same time Figure 2 As shown, the liquid outlet end of the centrifugal pump 8 is located at a high position in the cleaning chamber 7. At this time, water flow impact will be continuously generated to clean the foam plastic. Due to the continuous injection of water, the space in the cleaning chamber 7 is limited. It is necessary to drain the water in the cleaning chamber 7 regularly and discharge some of the cleaned foam plastic to avoid insufficient space. The centrifugal pump 8 can be started regularly to suck in the foam plastic, and then the cleaning chamber 7 can be opened when it is closed to discharge the cleaned foam plastic and water.

[0022] The discharged foam plastics will contain complete spherical foam plastic particles, incomplete hemispherical foam plastic particles and foam plastic residues. At this time, they only need to be dried and then separated through a filter to obtain many high-quality complete spherical foam plastic particles, which can be directly recycled and used, and the rest can be used as fillers or insulation materials.

[0023] Finally, after use, some foam plastic particles will remain in the recovery chamber 1, and these particles will stick to the inner wall. At this time, water can be injected into the processing chamber 101 through the drop bin 106 or gas can be introduced to lead away these residual foams and make them fall into the water in the water storage chamber 104 below. They can be taken out by liquid for cleaning, or they can be directly mixed into water using chemical agents to dissolve them.

[0024] The particles on the whole piece of foam plastic are kneaded out by two sets of kneading plates 4, which can effectively increase the proportion of complete spherical foam plastic particles compared to the existing physical method of extrusion and cutting.

[0025] The present embodiment adopts three groups of kneading boards 4, and the intervals between each group of kneading boards 4 are obviously different. In actual use, more groups of kneading boards 4 can be added to make the gap changes smoother and reduce the situation where a large amount of foam plastic remains in a certain group and cannot enter the next group.

[0026] Other specific supplementary measures include providing spherical protrusions on the surface of the kneading plate 4 and the inflatable airbag 5 to increase friction, and providing a stable air supply to the inflatable airbag 5 by providing a separate air pump.

[0027] Example 2: Reference Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 , a processing device for recycling and reusing foam plastics is basically the same as Example 1, and further: a plurality of piston cylinders 3 are fixedly connected in the equipment cavity 103, the piston cylinder 3 is fixedly connected to the telescopic end of the telescopic cylinder 2, the piston cylinder 3 is connected to an air inlet end and an air outlet end with a one-way valve, the air outlet end of the piston cylinder 3 is connected to an air outlet pipe 301, and a plurality of expansion air bags 5 are arranged at equal intervals on the kneading board 4, the expansion air bags 5 are connected to the air outlet pipe 301, and the expansion air bags 5 are provided with exhaust holes 501 arranged downwardly inclined, and the expansion end of the expansion air bag 5 in the initial state is located in the kneading board 4, that is, parallel to the surface of the kneading board 4, or slightly lower than the surface of the kneading board 4.

[0028] When a large number of expansion air bags 5 are set on the rubbing board 4, due to the setting of the piston cylinder 3, the piston cylinder 3 will continuously absorb external gas when the telescopic cylinder 2 is extended and retracted, and then introduce the gas into the expansion air bag 5, so that the internal air pressure of the expansion air bag 5 increases and then expands. At the same time, when the air intake is greater than the air output of the exhaust hole 501, the exhaust hole 501 will continuously discharge gas, and then some of the rubbed granular foam plastics will be blown into the rubbing board 4 below. At the same time, the expansion of the expansion air bag 5 will further compress the gap between the two rubbing boards 4, reduce the amount of foam plastic remaining between the two groups of rubbing boards 4, and reduce the situation that the gap is slightly smaller than the gap between the rubbing boards 4, but larger than the gap between the lower rubbing boards 4, and cannot be discharged. The expansion air bag 5 itself is relatively soft. When encountering a partition, it can shrink into the rubbing board 4 and play a role in auxiliary rubbing, rubbing more foam plastics.

[0029] Since the piston cylinder 3 cannot supply air all the time, there is an inhalation process. During the inhalation process, the expansion airbag 5 will gradually shrink, thereby increasing the interval between the two kneading plates 4. In this way, the gap between the kneading plates 4 will continue to increase and decrease, causing some foam plastics to continuously move left and right between the two groups of kneading plates 4, increasing the speed at which the foam plastics are transformed from large blocks to small particles.

[0030] like Figure 2 、 Figure 3 、 Figure 4 As shown, the surface of the rubbing board 4 is in contact with the partition. When the partition moves, the partition can scrape off some foam plastic particles attached to the rubbing board 4. At this time, if the size of the partition cavity 102 and the equipment cavity 103 is expanded, and the telescopic range of the telescopic cylinder 2 is increased, the foam plastic particles remaining on the rubbing board 4 and the expansion airbag 5 can be effectively scraped off by the scraper, so that they fall into the water storage cavity below.

[0031] Example 3: Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 , a processing device for recycling and reusing foam plastics, which is basically the same as Example 2, further comprising: an air storage bag 6 is installed in the blanking bin 106, and the air storage bag 6 is connected to a plurality of air nozzles 601 with pressure relief valves, and the air outlet end of the piston cylinder 3 is connected to a secondary pipe 303, the secondary pipe 303 is connected to the air storage bag 6, and the piston cylinder 3 is connected to a connecting pipe 302.

[0032] The gas is continuously guided into the air storage bag 6 through the piston cylinder 3. At this time, the air storage bag 6 will slowly discharge the gas inside, and then the gas will slowly blow into the blanking bin 106. These gases blow the outermost edge of the blanking bin 106, so that some foam plastics accumulated on the periphery can be continuously moved and finally enter between the kneading boards 4 for kneading treatment.

[0033] An electronic valve can be provided in the air nozzle, and the foam plastic can be quickly introduced into the space between the kneading plates 4 by continuously enlarging the expansion airbag 6 .

[0034] Example 4: Reference Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 , a processing device for recycling and reusing foam plastics, which is basically the same as Example 3, further comprising: a plurality of grooves are provided on the kneading plate 4, a spring member 402 is connected in the groove, a knocking block 401 is slidably connected in the groove, and the knocking block 401 is connected to the spring member 402. When the kneading plate 4 moves laterally, the knocking block 401 will continuously contact the partition and vibrate.

[0035] By setting the knocking block 401, when the rubbing board 4 moves back and forth, the knocking block will continuously contact the partition, thereby generating some vibrations through collision, and shaking off some foam plastics adhering to the rubbing board 4 and the expansion airbag 5.

[0036] Example 4: Reference Figure 1-9 A foam plastic recycling and reuse processing method, used for a foam plastic recycling and reuse processing device, mainly includes the following steps: Step 1: Continuously put the foam plastics to be recycled into the drop bin 106, and start the telescopic cylinder 2 to process the foam plastics in the processing bin 101; Step 2: After being processed by the kneading board 4, the large pieces of foam plastic will be transformed into spherical particles and residues, and finally fall into the water storage chamber 104 below; Step 3: Connect the water inlet pipe on the water storage chamber 104 to the external water supply pipe, start the centrifugal pump 8 and the motor 701, suck the foam plastic particles in the water storage chamber 104 into the cleaning chamber 7, and clean the foam plastic particles in the cleaning chamber 7; Step 4: Open the drain pipe on the cleaning chamber 7 to drain the excess water and finally drain the cleaned foam plastic particles.

[0037] The present invention uses two groups of counter-moving rubbing boards 4 to continuously squeeze and rub the foam plastic between the rubbing boards 4, thereby causing the complete spherical particles on the foam plastic to continuously fall off, then fall into the water below, and finally enter the cleaning chamber 7 for cleaning. At this time, there are many complete spherical foam plastic particles, which can be directly used for the preparation of new foam boards, reducing the waste of resources.

[0038] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
