[0031] Embodiment

[0032] As Figure 1 and Figure 2 shown, an environment-friendly waste plastic fine processing mobile workshop includes a carriage 1, and two rows of equipment are integrally and juxtaposedly installed inside the carriage 1; one row of equipment includes a plastic crusher 2, a storage box 3, and a support stand 18 installed in sequence from the rear of the vehicle to the front of the vehicle. A power control cabinet 17 and a negative pressure adsorber 4 are installed on the top surface of the support stand 18. The negative pressure adsorber 4 is located outside the power control cabinet 17. A water circulation pool 19 and a generator set 20 are installed at the bottom of the support stand 18. The water circulation pool 19 is arranged outside the generator set 20;

[0033] Axially distributed transmission rods 22 are installed at the bottom of the carriage 1. A gear transmission box 21 is sleeved on the outer wall of the transmission rods 22. The gear transmission box 21 is drivingly connected to the generator set 20. The generator set 20 is electrically connected to the power control cabinet 17. The power control cabinet 17 is used to supply power to each device; the design of the gear transmission box and the generator set can make the power of the entire processing workshop come from the rotation of the vehicle transmission rod, eliminating the need for a separate power source and reducing the production cost of the vehicle; the power control cabinet can control each device;

[0034] The other row of equipment includes an extruder 8, an extrusion material cooling mechanism 6, and a granulator 5 installed in sequence from the front of the vehicle to the rear of the vehicle; the discharge port of the plastic crusher 2 is communicated with the top inlet of the extruder 8. The extrusion material cooling mechanism 6 is used to cool the plastic filaments. The granulator 5 is used to cut the plastic filaments. The storage box 3 is used to store the cut plastic particles; by integrating the extruder, the extrusion material cooling mechanism and the granulator in the carriage, fine processing of waste plastics can be realized, the processing is more thorough, there is no need for secondary processing and transfer, and the granular material in the storage box can be directly taken down and sold later;

[0035] The interior of the extruded material cooling mechanism 6 is in communication with the water circulation pool 19, and the water circulation pool 19 is used for circulating and purifying water. The top of the extruded material cooling mechanism 6 is provided with an exhaust gas treatment component 7 at intervals. The exhaust gas treatment component 7 is used for adsorbing and purifying the exhaust gas generated by the extruded material, and the exhaust gas treatment component 7 is in communication with the negative pressure adsorber 4; a dust adsorber 9 is installed on the inner top surface of the carriage 1, and the dust adsorber 9 is connected to the extruder 8 through a second material suction hose 901;

[0036] Through the water circulation pool, the exhaust gas treatment component, and the dust adsorber, water purification treatment, harmful gas purification treatment, and dust purification treatment in the workshop can be realized, enabling the entire workshop to meet environmental protection requirements;

[0037] Each of the above-mentioned devices has been structurally designed and reasonably arranged in the carriage, making the entire carriage highly integrated, enabling mobile processing, capable of completing processing at the waste plastic site, eliminating the costs of separately transporting waste plastic, manual sorting, and loading and unloading operations; compared with existing devices, the investment cost and production cost can be greatly reduced.

[0038] As Figure 1 and Figure 2 shown, the carriage 1 includes a bottom plate 101, a front plate body 102, a top plate 103, a carriage door 104, a first opening and closing side plate 105, and a second opening and closing side plate 106; one end of the surface of the bottom plate 101 is vertically provided with a front plate body 102, and the other side of the surface is hinged with a carriage door 104. The top of the bottom plate 101 is provided with a top plate 103. One side of the top plate 103 is rotatably connected to the first opening and closing side plate 105, and the other side is rotatably connected to the second opening and closing side plate 106; both sides are designed as side plates that can be automatically opened and closed, and the power source is a pneumatic rod. Both sides can be opened to facilitate heat dissipation, maintenance, and loading and unloading; a square hole is opened inside the first opening and closing side plate 105, and a transparent cover plate 1051 is hinged inside the square hole. The transparent cover plate is arranged opposite to the power control cabinet, facilitating workers' observation. At the same time, when opening and closing regulation is required, the transparent cover plate can be opened without opening all the side plates, facilitating on-site control and reducing the operation difficulty;

[0039] As Figure 9As shown, the extruded material cooling mechanism 6 includes a cooling tank 601, a heat dissipation fan 602, a guiding idler 603, and a conveying wheel 604. Inside the cooling tank 601, a first cooling chamber 6011, a second cooling chamber 6012, and a third cooling chamber 6013 that are independent of each other are sequentially arranged along the conveying direction. The discharge port of the extruder 8 extends into the first cooling chamber 6011. A heat dissipation fan 602 is installed at the inner bottom of the first cooling chamber 6011. A cooling water spraying mechanism 16 is installed at the inner top of the second cooling chamber 6012. A conveying wheel 604 is installed in the third cooling chamber 6013. Guiding idlers 603 are installed inside both the first cooling chamber 6011 and the second cooling chamber 6012. An exhaust gas treatment component 7 is installed on the top of the cooling tank 601; the extruded plastic wire first passes through the first cooling chamber. At this time, the strength of the wire is the lowest and it cannot directly contact water. Therefore, the heat dissipation fan is first used to cool down the wire to achieve preliminary solidification. In this way, the preliminarily solidified wire can contact water in the second cooling chamber, and at the same time, by adjusting the wind speed, the cooling effect can be adjusted, and the regulation is simple; the wire is sprayed with water for cooling in the second cooling chamber, so that the wire solidifies to the required strength; the design of each guiding idler can support and guide the wire to prevent the wire from sagging.

[0040] As Figure 10 and Figure 11 shown, the cooling water spraying mechanism 16 includes a water guide pipe 1601, a wind guide cover 1602, a cooling fan 1603, a nozzle 1604, and a heat conducting copper bar 1605. A wind guide cover 1602 is provided at the top of the water guide pipe 1601. A cooling fan 1603 is installed at one end inside the wind guide cover 1602. A plurality of nozzles 1604 are vertically and spaced apart on the bottom surface of the water guide pipe 1601. The area between the inside of the water guide pipe 1601 and the adjacent nozzles 1604 is a cooling section. Heat conducting copper bars 1605 are installed inside each cooling section. A part of the heat conducting copper bar 1605 is placed inside the water guide pipe 1601, and the other part extends into the wind guide cover 1602. The number of heat conducting copper bars 1605 in each cooling section along the water conveying direction increases in sequence. The distribution of the heat conducting copper bars 1605 is used to make the temperature in each cooling section along the water conveying direction decrease in sequence; the water guide pipe is communicated with the water circulation pool. When water flows, the heat in it will be conducted to the upper part through the heat conducting copper bar. The cooling fan can cool down each heat conducting copper bar to achieve rapid cooling of the water, ensure that the discharged water temperature is relatively low, and achieve cooling of the wire; at the same time, because the number of heat conducting copper bars in each cooling section is different, the temperature of the water will gradually decrease during transportation, which ensures that the water temperatures sprayed by each nozzle are different, realizes slow and segmented cooling of the wire, and avoids premature contact of the plastic wire with low-temperature cold water.

[0041] As Figure 1 , Figure 7 and Figure 8As shown in the figure, an adsorption hood 1501 is installed at the discharge port of the pelletizer 5. The top of the adsorption hood 1501 is connected to a second rigid suction pipe 15. The second rigid suction pipe 15 is fixed to the bottom surface of the top plate 103. The discharge end of the second rigid suction pipe 15 is connected to a negative pressure adsorption machine 4. An inclined downward mesh-structured guide plate 401 is installed inside the negative pressure adsorption machine 4. A blower 402 is provided at the bottom end of the guide plate. A discharge pipe 403 is provided at a position on the side wall of the negative pressure adsorption machine 4 opposite to the guide plate 401. The discharge pipe 403 extends obliquely downward to the top of the storage tank 3; the granular materials cut by the pelletizer will be discharged to the adsorption hood, then sucked by negative pressure to the second rigid suction pipe, and finally discharged into the storage tank through the guide plate and the discharge pipe. The whole process realizes automatic material suction and collection, without the need for workers to transfer in the middle, and the automation degree of the whole workshop is higher.

[0042] As Figure 8 shown, the waste gas treatment component 7 includes an upper pipe body 701, a filter cylinder 702, a guide air pipe 703 and an attracting hood 704. The attracting hood 704 is spaced above the cooling tank 601. The top of the attracting hood 704 is connected to the guide air pipe 703. An upper pipe body 701 is vertically provided on the bottom surface of the second rigid suction pipe 15. A filter cylinder 702 is installed between the upper pipe body 701 and the guide air pipe 703; the upper pipe body is connected in parallel to the second rigid suction pipe, so that the negative pressure of the whole waste gas treatment component comes from the negative pressure adsorption machine, without the need to design a blower separately. At the same time, the filter cylinder is designed at the lower part of the upper pipe body to prevent waste gas from being conducted into the second rigid suction pipe and avoid the influence of waste gas on the finished product quality of the granular materials. A filter screen, non-woven fabric and activated carbon layer are successively arranged in the filter cylinder from bottom to top; the filter cylinder is detachable and replaceable; the attracting hoods are distributed on the cooling tank and can adsorb harmful gases effectively over a large area.

[0043] As Figure 3 and Figure 4 shown, an inner guide rail 1011 is provided on the surface of the bottom plate 101. A tail plate 12 is rotatably installed at the rear of the carriage 1. The bottom end of the tail plate 12 is connected to a flipping drive assembly 13. The flipping drive assembly 13 is installed at the rear part of the bottom surface of the carriage 1. An outer guide rail 1201 is provided on the surface of the tail plate 12. The outer guide rail 1201 and the inner guide rail 1011 are arranged oppositely. The plastic crusher 2 is slidably installed on the outer guide rail 1201 or the inner guide rail 1011; during processing, the flipping drive assembly can drive the tail plate to flip open and be flush with the bottom plate. Then the plastic crusher can be moved out to the tail plate along the inner guide rail and the outer guide rail. Then the flipping drive assembly opens the tail plate and lowers it to the ground, facilitating workers to feed materials; the flipping drive assembly includes a flipping hydraulic rod, a lifting hydraulic rod and a fixing block. The lifting hydraulic rod is fixed to the bottom surface of the carriage. The bottom end of the lifting hydraulic rod is connected to the fixing block. The outer wall of the fixing block is connected to the flipping hydraulic rod. The end of the flipping hydraulic rod is rotatably connected to the movable end of the tail plate; it is a conventional structure in the prior art;

[0044] The top side wall of the extruder 8 communicates with a first rigid suction pipe 801. One end of the first rigid suction pipe 801 is connected to a first flexible suction pipe 802. The first flexible suction pipe 802 communicates with the outlet of the plastic crusher 2. The first rigid suction pipe 801 is bent and fixed at the bottom edge of the top plate 103. The first rigid suction pipe can achieve long-distance transportation and avoid the negative pressure adsorption machine, optimizing the structural design. The design of the first flexible suction pipe can meet the needs of connecting the plastic crusher at different positions.

[0045] As Figure 5 and Figure 6 shown, both the inner guide rail 1011 and the outer guide rail 1201 are strip-shaped cuboid structures. A sunken movable groove 10111 is formed in the middle of the outer end surface of the inner guide rail 1011. A storage hole 10112 is formed inside the inner guide rail 1011. The storage hole 10112 communicates with the inner side of the movable groove 10111. A middle support rod 14 is slidably embedded in the movable groove 10111. The inner end of the middle support rod 14 is slidably embedded in the storage hole 10112. A positioning groove 12011 for fitting and inserting the middle support rod 14 is formed in the end surface of the outer guide rail 1201. When the tail plate is turned and opened, there is a large gap between the tail plate and the bottom plate. This causes the plastic crusher to be dragged outwards not smoothly and with insufficient stability. With the design of the above-mentioned middle support rod, it is convenient to compensate for the gap and then support the plastic crusher, so that the plastic crusher can be stably pulled out. The design of the movable groove enables the middle support rod to be retracted, facilitating integration with the inner guide rail and not affecting the closing of the compartment door. It can also ensure that when the middle support rod is pulled out, the two side parts of the movable groove of the inner guide rail can support the plastic crusher, enabling the plastic crusher to move outwards along the two side parts of the movable groove and the middle support rod. The design of the positioning groove can position the middle support rod pulled outwards to ensure stability. The middle support rod includes a support part and a limiting part. The limiting part is slidably embedded in the guide storage hole, and the support part is slidably embedded in the movable groove.

[0046] An outer traction motor 11 is installed on the bottom surface of the tail plate 12. An inner guide rail 1011 is provided on the surface of the bottom plate 101. An inner traction motor 10 is arranged at the inner end of the inner guide rail 1011. The inner traction motor 10 is connected to the inner end of the plastic crusher 2. The outer traction motor 11 is connected to the outer end of the plastic crusher 2. The outer traction motor 11 and the inner traction motor 10 are used to drive the plastic crusher to automatically enter and exit without manual operation.

[0047] When the present invention is implemented:

[0048] During recycling and processing, the circulation vehicle drives into the factory area. Then, the flipping drive assembly 13 drives the tailboard 12 to flip outward by 90°. The tailboard 12 is flush with the bottom plate 101. Then, the worker pulls the middle support rod 14 outward, so that the end of the middle support rod 14 is inserted into the positioning groove 12011 for positioning; the inner guide rail 1011 and the outer guide rail 1201 are made continuous as a whole;

[0049] Then, the external traction motor 11 drives the plastic crusher 2 in the carriage 1 to move outward. The plastic crusher 2 moves along the inner guide rail 1011 and the middle support rod 14 to the outer guide rail 1201 of the tailboard 12. During the movement, then the flipping drive assembly 13 drives the tailboard 12 to move downward. During the movement of the above plastic crusher 2, the first suction hose 802 is stretched to ensure normal feeding of the material by negative pressure suction;

[0050] Then, start each device through the power control cabinet 17. The worker puts the waste plastic into the plastic crusher 2. The dust generated during processing is sucked by the negative pressure of the dust adsorber 9. The filter screen in the dust adsorber 9 filters the dust, and then discharges the qualified air;

[0051] The crushed plastic is sucked to the extruder 8 by negative pressure. The plastic is melted and extruded, and then the plastic is pulled out by traction. The cooling fan 602 cools the drawn wire preliminarily. Then, the plastic wire moves into the second cooling chamber 6012, and the guiding roller 603 supports and guides the plastic wire; the water in the water circulation pool 19 is filtered by the filter screen and activated carbon particles, and then discharged to one end of the water guide pipe 1601 close to the extruder 8 through the water pump. When the water circulates, the heat in the water is conducted out to the air guide cover 1602 by the heat conducting copper rod 1605, and the cooling fan dissipates the heat of each heat conducting copper rod 1605, so that the water cools down section by section during the flow. The water temperature discharged by each nozzle decreases in turn along the water flow direction, realizing the sectional cooling of the plastic wire; the water gathered in the second cooling chamber 6012 is pumped to the water circulation pool 19 for circulating purification;

[0052] During the above cooling process, the plastic wire will emit a lot of harmful gases. The negative pressure adsorption machine 4 generates negative pressure, so that the harmful gases are adsorbed into the suction hood 704 above, and then the harmful gases are purified by the filtering material in the filter cartridge 702, and finally the purified gas is discharged;

[0053] The plastic wire after cooling and shaping is output to the granulator 5, and the plastic wire is cut into small particles. The negative pressure adsorption machine 4 can suck the plastic particles by negative pressure, so that the plastic particles move onto the guide plate 401, and then are discharged to the storage box 3 along the discharge pipe 403 to realize storage;
