Description

Technical Field

[0002] Plastic is an important organic synthetic polymer material with a wide range of applications. With the increasing emphasis on environmental protection in recent years, plastic waste can be recycled and made into plastic particles for reuse.

[0003] The existing environmentally friendly treatment equipment for plastic particle waste has the following problems:

[0004] When existing environmentally friendly treatment equipment for plastic waste particles processes large-volume plastic waste, in order to avoid monomer waste occupying more crushing space, the waste is first coarsely crushed to reduce it to a certain size range, and then finely crushed to further reduce its particle size. When the waste is crushed in the above manner, the process is cumbersome and complicated. It is not possible to directly finely crush the waste plastic while reducing the internal space of the crushing container occupied by large-volume waste monomers. In addition, traditional environmentally friendly treatment equipment for plastic waste particles does not have the ability to clean the dust on the surface of the waste. Therefore, it cannot meet the existing use requirements of environmentally friendly treatment equipment for plastic waste particles. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present solution provides an environmentally friendly plastic particle waste treatment equipment that can directly crush the waste plastics while reducing the internal space occupied by larger monomer waste materials in the crushing container, and can clean the dust on the surface of the waste materials to ensure the quality of the waste materials after crushing.

The heating mechanism is arranged on the side wall of the crushing barrel, the jet mechanism is arranged on the side wall of the crushing barrel below the heating mechanism, and the dust flow mechanism is arranged on the inner wall of one end of the crushing barrel close to the heating mechanism.

[0008] Preferably, the heating mechanism comprises a heating frame, a heating chamber, a thermoelectric cooling sheet, a heat-conducting copper column and a copper mesh cylinder, the heating frame is arranged on the side wall of the crushing cylinder away from the base, the heating chamber is arranged inside the crushing cylinder between the screening mesh plate and the heating frame, multiple groups of the thermoelectric cooling sheets are arranged on the side wall of the heating frame, the heat-conducting copper column is arranged at the cooling end of the thermoelectric cooling sheet, and the copper mesh cylinder is arranged on the side of the heat-conducting copper column away from the thermoelectric cooling sheet; the jet mechanism comprises an air pump and a hot air pipe, multiple groups of the air pumps are arranged through the inner wall of the crushing cylinder close to the base, and the air pumps are arranged at the crushing cylinder. The inner wall of the crushing cylinder above the tool, the hot air pipe is connected between the copper mesh cylinder and the suction end of the vacuum pump; the dust flow mechanism includes an insulation ring plate, a dust flow chamber, an L-shaped mesh plate, a copper sleeve and a cooling copper rod. The insulation ring plate is arranged on the inner wall of one end of the crushing cylinder close to the heating frame, and the dust flow chamber is arranged inside the crushing cylinder above the insulation ring plate. Multiple groups of L-shaped mesh plates are arranged between the upper wall of the insulation ring plate and the inner wall of the crushing cylinder, and multiple groups of copper sleeves are penetrated through the inner wall of the insulation ring plate. The cooling copper rod penetrates the crushing cylinder and the insulation ring plate and is arranged between the copper sleeve and the cooling end of the thermoelectric refrigeration plate.

[0009] Specifically, a controller is provided on the side wall of the crushing barrel.

[0010] Wherein, the controller is electrically connected to the crushing motor, the downward pressure electromagnet, the thermoelectric cooling sheet and the air pump respectively.

[0011] A method for using an environmentally friendly treatment device for plastic particle waste:

[0012] Step 1: Pour the waste plastic into the crushing cylinder, and the waste plastic falls into the upper wall of the screening mesh plate. The crushing motor drives the crushing cutter through the power end to crush the waste plastic placed on the upper wall of the screening mesh plate;

[0013] Step 2: The pressing electromagnet is energized to generate magnetism. The pressing electromagnet and the pushing magnet are arranged with opposite poles. The pressing electromagnet is fixed on the upper wall of the pressing platform and pushes the magnet by magnetic attraction. The pushing magnet drives the push rod to slide along the inner wall of the pressing platform by pushing the spring to deform. The push rod drives the gravity ball to rise. Then the pressing electromagnet is powered off and demagnetized. The pushing spring is elastically reset to drive the gravity ball to perform free fall. The gravity ball falls to press down the waste plastic, speeding up the falling speed of the waste plastic and increasing the crushing rate of the crushing tool for the waste plastic.

[0014] Step 3: When the waste plastic with a larger volume is put into the crushing cylinder, it occupies more space, resulting in less waste plastic put into the crushing cylinder. At this time, the thermoelectric refrigeration plate heats the heat-conducting copper column through the heating end, and the temperature of the heat-conducting copper column increases to heat the copper mesh cylinder. The vacuum pump draws the outside air into the copper mesh cylinder through the vacuum end, and the copper mesh cylinder heats the outside air. The heated air passes through the hot air pipe and the exhaust end of the vacuum pump into the heating chamber. According to the requirements of the operator, the vacuum pump appropriately heats the waste plastic near the end of the crushing tool in the heating chamber. The waste plastic in the heating chamber is gradually softened by the impact of the hot air, and the hardness and supporting force of the waste plastic decrease. Under the downward pressure of the gravity ball, the gap between the heated waste plastic is reduced, thereby providing more waste plastic placement space for the crushing cylinder. At the same time, softening makes the waste plastic more likely to break when subjected to external force, which helps the crushing tool to crush the waste plastic more effectively. The crushed waste plastic falls into the feeding chamber through the mesh of the screening mesh plate;

[0015] Step 4: Use a plug to block the discharge port in advance. The hot air flows upward after impacting the waste plastic. The gap between the softened waste plastic is reduced, thereby reducing the airflow rate. Therefore, under the partition of the insulation ring plate, part of the upstream hot air flows into the dust flow chamber through the junction of the heating chamber and the insulation ring plate, and the other part flows into the dust flow chamber through the copper sleeve. The thermoelectric cooling plate cools the cooling copper rod through the cooling end, and the cooling copper rod cools the air flowing through the copper sleeve, so that the air flowing into the dust flow chamber is relatively low in temperature and will not soften the waste plastic inside the dust flow chamber. The air flows to the opening of the crushing cylinder to take away the dust on the surface of the waste plastic, thereby reducing the dust content mixed in the waste plastic after crushing and improving the treatment efficiency of the waste plastic.

[0016] The beneficial effects achieved by adopting the above structure are as follows:

[0017] Compared with the prior art, the present invention adopts a softening method to reduce the supporting force and press down to crush. By setting a pressure-type crushing mechanism and a softening dust blowing mechanism, under the coordinated use of the crushing mechanism, the pressing mechanism, the heating mechanism, the jet mechanism and the dust flowing mechanism, the hardness and supporting force of the waste plastics are reduced by softening the waste plastics before crushing. Under the downward pressure of the gravity of the gravity ball, the gaps between the waste plastics entering the heating chamber are reduced, thereby increasing the space for storing the waste plastics in the dust flowing chamber. At the same time, by cooling the hot air flowing through the copper sleeve after softening, it can be ensured that the gaps between the waste plastics in the dust flowing chamber will not be reduced, which is convenient for the surface absorption of the waste plastics in the dust flowing chamber. The attached dust flows out of the crushing cylinder, thereby reducing the probability of dust mixed in the waste plastic after crushing. The gap between the softened waste plastic is reduced, thereby reducing the airflow rate. Therefore, under the partition of the heat insulation ring plate, part of the upstream hot air flows into the dust flow chamber through the junction of the heating chamber and the heat insulation ring plate, and the other part flows into the dust flow chamber through the copper sleeve. The thermoelectric cooling plate cools the cooling copper rod through the cooling end, and the cooling copper rod cools the air flowing through the copper sleeve, so that the air flowing into the dust flow chamber has a relatively low temperature, which will not soften the waste plastic inside the dust flow chamber. The air flows to the opening of the crushing cylinder to take away the dust contained on the surface of the waste plastic. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] A controller 33 is disposed on the side wall of the crushing cylinder 2 .

[0038] The controller 33 is electrically connected to the crushing motor 6 , the downward pressing electromagnet 14 , the thermoelectric cooling sheet 21 and the air pump 25 , respectively.

[0039] A method for using an environmentally friendly treatment device for plastic particle waste:

[0040] Step 1: Pour the waste plastic into the crushing cylinder 2, and the waste plastic falls onto the upper wall of the screening mesh plate 5. The crushing motor 6 drives the crushing cutter 7 through the power end to crush the waste plastic placed on the upper wall of the screening mesh plate 5;

[0041] Step 2: The pressing electromagnet 14 is energized to generate magnetism. The pressing electromagnet 14 and the pushing magnet 15 are arranged with opposite poles. The pressing electromagnet 14 is fixed on the upper wall of the pressing platform 11 and pushes the magnet 15 by magnetic attraction. The pushing magnet 15 drives the push rod 13 to slide along the inner wall of the pressing platform 11 by the deformation of the pushing spring 16. The push rod 13 drives the gravity ball 12 to rise in height. Then, the pressing electromagnet 14 is powered off and demagnetized. The pushing spring 16 elastically resets and drives the gravity ball 12 to perform free fall. The gravity ball 12 falls to press down on the waste plastic, accelerates the falling speed of the waste plastic, and improves the crushing rate of the crushing tool 7 for the waste plastic.

[0042] Step 3: When the waste plastic with a larger volume is put into the crushing cylinder 2, it occupies more space, resulting in less waste plastic put into the crushing cylinder 2. At this time, the thermoelectric cooling plate 21 heats the heat-conducting copper column 22 through the heating end. The temperature of the heat-conducting copper column 22 increases and heats the copper mesh cylinder 23. The vacuum pump 25 draws the outside air into the copper mesh cylinder 23 through the vacuum end. The copper mesh cylinder 23 heats the outside air. The heated air passes through the hot air pipe 26 and the exhaust end of the vacuum pump 25 into the heating chamber 20. According to the requirements of the operator, the vacuum pump 25 heats the heating chamber 20. 0 The waste plastic near one end of the crushing tool 7 is properly heated, and the waste plastic inside the heating chamber 20 is gradually softened by the impact of hot air, and the hardness and supporting force of the waste plastic decrease. Under the downward pressure of the gravity ball 12, the gap between the heated waste plastic is reduced, thereby providing more waste plastic placement space inside the crushing cylinder 2. At the same time, softening makes the waste plastic more likely to break when subjected to external force, which helps the crushing tool 7 to crush the waste plastic more effectively. The crushed waste plastic falls into the feed chamber 8 through the mesh of the screening mesh plate 5;

[0043] Step 4: Use a plug to block the discharge port 9 in advance. The hot air flows upward after impacting the waste plastic. The gap between the softened waste plastic is reduced, thereby reducing the air flow rate. Therefore, under the partition of the insulation ring plate 28, a part of the upstream hot air flows into the dust flow chamber 29 through the junction of the heating chamber 20 and the insulation ring plate 28, and the other part flows into the dust flow chamber 29 through the copper sleeve 31. The thermoelectric cooling plate 21 cools the cooling copper rod 32 through the cooling end, and the cooling copper rod 32 cools the air flowing through the copper sleeve 31, so that the air flowing into the dust flow chamber 29 has a relatively low temperature and will not soften the waste plastic inside the dust flow chamber 29. The air flows to the opening of the crushing cylinder 2 to take away the dust on the surface of the waste plastic, thereby reducing the dust content mixed in the waste plastic after crushing and improving the treatment efficiency of the waste plastic.

[0044] When in use, the waste plastic is poured into the crushing cylinder 2, and the waste plastic falls onto the upper wall of the screening mesh plate 5. When the waste plastic with a larger volume is put into the crushing cylinder 2, it occupies more space, resulting in less waste plastic put into the crushing cylinder 2;

[0045] Specifically, the controller 33 controls the thermoelectric cooling sheet 21 to start, and the thermoelectric cooling sheet 21 heats the heat-conducting copper column 22 through the heating end. The temperature of the heat-conducting copper column 22 increases and heats the copper mesh tube 23. The controller 33 controls the vacuum pump 25 to start, and the vacuum pump 25 draws outside air into the copper mesh tube 23 through the vacuum end. The copper mesh tube 23 heats the outside air, and the heated air passes through the hot air pipe 26 and the exhaust end of the vacuum pump 25 into the heating chamber 20. According to the requirements of the operator, the vacuum pump 25 appropriately heats the waste plastics in the heating chamber 20 near the end of the crushing tool 7. The waste plastics in the heating chamber 20 are gradually softened by the impact of the hot air, and the hardness and supporting force of the waste plastics decrease. Under the downward pressure of the gravity ball 12, the gaps between the heated waste plastics are reduced, thereby providing more waste plastic placement space for the crushing tube 2. At the same time, softening makes the waste plastics more likely to break when subjected to external forces, which helps the crushing tool 7 to crush the waste plastics more effectively.

[0046] The controller 33 controls the crushing motor 6 to start, and the crushing motor 6 drives the crushing tool 7 through the power end to crush the waste plastic placed on the upper wall of the screening mesh plate 5. The controller 33 controls the pressing electromagnet 14 to start, and the pressing electromagnet 14 is energized to generate magnetism. The pressing electromagnet 14 and the pushing magnet 15 are arranged with opposite poles. The pressing electromagnet 14 is fixed on the upper wall of the pressing platform 11 and pushes the magnet 15 through magnetic adsorption. The pushing magnet 15 drives the push rod 13 to slide along the inner wall of the pressing platform 11 through the deformation of the pushing spring 16, and the push rod 13 drives the gravity ball 12 to rise in height. Then the controller 33 controls the pressing electromagnet 14 to cut off the power and demagnetize, and the pushing spring 16 elastically resets to drive the gravity ball 12 to perform free fall motion. The gravity ball 12 falls to press down the waste plastic, accelerates the falling speed of the waste plastic, and improves the crushing rate of the crushing tool 7 for the waste plastic.

[0047] The crushed waste plastic falls into the feed cavity 8 through the mesh of the screening mesh plate 5, and the discharge port 9 is blocked in advance with a plug. The hot air flows upward after impacting the waste plastic, and the gaps between the softened waste plastic are reduced, thereby reducing the air flow rate. Therefore, under the isolation of the heat insulation ring plate 28, part of the upstream hot air flows into the dust flow cavity 29 through the junction of the heating cavity 20 and the heat insulation ring plate 28, and the other part flows into the dust flow cavity 29 through the copper sleeve 31. The thermoelectric cooling plate 21 cools the cooling copper rod 32 through the cooling end, and the cooling copper rod 32 cools the air flowing through the copper sleeve 31, so that the air flowing into the dust flow cavity 29 has a relatively low temperature, and the waste plastic in the dust flow cavity 29 will not be softened. The air flows to the opening of the crushing cylinder 2 to take away the dust on the surface of the waste plastic, thereby reducing the dust content mixed in the waste plastic after crushing and improving the treatment efficiency of the waste plastic. Repeat the above operation when using it next time.

The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.

The environmentally friendly treatment equipment for plastic particle waste according to claim 3 is characterized by: The pressing mechanism (10) comprises a pressing platform (11), a gravity ball (12), a pushing rod (13), a pressing electromagnet (14), a pushing magnet (15) and a pushing spring (16); the pressing platform (11) is arranged on the upper wall of the crushing barrel (2); the pushing rod (13) penetrates the inner wall of the pressing platform (11); and the pressing electromagnet (14) is arranged on the upper wall of the pressing platform (11) outside the pushing rod (13).

5. The environmentally friendly treatment equipment for plastic particle waste according to claim 4 is characterized in that: The gravity ball (12) is arranged on the bottom wall of the lower push rod (13), the pushing magnet (15) is arranged on the upper wall of the lower push rod (13), the downward pressing electromagnet (14) and the pushing magnet (15) are arranged opposite to each other, and the pushing spring (16) is arranged between the gravity ball (12) outside the lower push rod (13) and the downward pressing platform (11).

6. The method for using the equipment for environmentally friendly treatment of plastic particle waste according to claim 5, characterized in that: Step 1: waste plastics fall onto the upper wall of the screening mesh plate (5), and the crushing motor (6) drives the crushing cutter (7) through the power end to crush the waste plastics placed on the upper wall of the screening mesh plate (5); Step 2: Pushing the spring (16) to elastically return to its original position drives the gravity ball (12) to perform free fall motion, and the gravity ball (12) falls to press down the waste plastics; Step 3: The waste plastic inside the heating chamber (20) is gradually softened by the impact of the hot air, and the hardness and supporting force of the waste plastic decrease. Under the downward pressure of the gravity ball (12), the gaps between the heated waste plastic are reduced; Step 4: The cooling copper rod (32) cools the air flowing through the copper sleeve (31), so that the air flowing into the dust flow chamber (29) has a relatively low temperature and does not soften the waste plastics in the dust flow chamber (29). The air flows toward the opening of the crushing cylinder (2) and carries away the dust on the surface of the waste plastics.
