Description

Technical Field

[0001] The utility model relates to the technical field of waste plastics, in particular to a waste plastic decomposition heater. Background Technique

[0002] Plastics refer to materials with resin as the main component and additives such as plasticizers, fillers, lubricants, and colorants as auxiliary components, which can be formed by flowing during the processing process. Plastics are synthetic high-molecular compounds that can freely change their shapes. Waste plastics refer to plastics that have been used in civil, industrial, and other applications and have finally been phased out or replaced. During the recycling and treatment of waste plastics, dry chemical recycling is a commonly used method, and a decomposition heater device is required during the treatment process.

[0003] As disclosed in a waste plastic decomposition heater in Chinese Patent CN108160671A, the arc-shaped cover plate is opened through a handle, and then the waste plastics are sent into the interior of the box body. Then, the electromagnetic heater provided in the electromagnetic heating box is controlled to be turned on through a PLC controller. At this time, the servo motor is controlled to be turned on through the PLC controller. The output shaft of the servo motor drives the connected rotating shaft to rotate through a coupling. The rotation of the rotating shaft drives the connected main shaft to rotate. The rotation of the main shaft drives the connected connecting plate to rotate. The rotation of the connecting plate drives the conical rotating body connected through the rotating shaft to rotate. The rotation of the conical rotating body presses and fits the waste plastics against one side inside the box body, facilitating the heating and decomposition of the waste plastics.

[0004] For this structure, although the waste plastics can be pressed and fitted against one side inside the box body through the rotation of the conical rotating body and the waste plastics can be heated and decomposed, when the waste plastics are heated and decomposed, when pressed by the conical rotating body, some waste plastics are located at the rotating shaft, resulting in uneven extrusion of the waste plastics. Therefore, we propose a waste plastic decomposition heater that can evenly extrude the waste plastics and has a better decomposition and heating effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a waste plastic decomposition heater to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A waste plastic decomposition heater, including a barrel body, support legs are fixedly installed at the bottom of the barrel body, a negative pressure suction pump is arranged at the bottom of the barrel body, a PLC controller is arranged at the top of the barrel body, an electromagnetic heater is fixedly installed inside the barrel body, a first electromagnetic valve is arranged inside the electromagnetic heater, a second electromagnetic valve is arranged below the first electromagnetic valve, and a processing component is arranged inside the barrel body. The processing component includes a decomposition component arranged inside the barrel body, and a feeding component is arranged above the decomposition component.

[0007] Preferably, the decomposition component includes a support frame fixedly installed on the top surface of the barrel body. One end of the support frame far from the top surface of the barrel body is fixedly installed with a motor. The output end of the motor is fixedly installed with a reciprocating lead screw. A sleeve block is sleeved on the outer wall of the reciprocating lead screw. A rolling plate is fixedly installed on the top surface of the sleeve block. A sliding rod is fixedly installed on the outer wall of the sleeve block. A spring is sleeved on the outer wall of the sliding rod. A clamping plate is slidably arranged on the outer wall of the sliding rod. The outer wall of the rolling plate is rotatably connected with a limiting ring. A clamping block is fixedly installed on the inner wall of the limiting ring. One end of the reciprocating lead screw far from the motor is rotatably connected with a cross plate.

[0008] Preferably, the feeding component includes a limiting rod fixedly installed on the top surface of the limiting ring. One end of the limiting rod far from the limiting ring is fixedly installed with a fixing block. A sliding ring is fixedly installed on the outer wall of the fixing block. A fixing ring is fixedly installed on the inner wall of the barrel body. The bottom of the fixing ring is hinged with an arc plate.

[0009] Preferably, the end of the clamping plate is arranged in an inclined plane, and the outer wall of the clamping block is arranged in an inclined plane. The rolling plate is rotatably connected with the inner wall of the limiting ring. Under its limitation, when the reciprocating lead screw rotates forward, the sliding rod fixedly installed on the outer wall of the sleeve block rotates accordingly. The clamping plate sleeved on the outer wall of the sliding rod contacts and presses against the inclined plane of the limiting ring fixedly installed on the inner wall of the limiting ring, so that the clamping plate and the clamping block are no longer clamped, so that the sleeve block can drive the rolling plate fixedly installed on its top surface to rotate accordingly.

[0010] Preferably, the top surface of the limiting ring is fixedly installed with the limiting rod, and the outer wall of the limiting rod is slidably arranged inside the electromagnetic heater. Under its limitation, when the reciprocating lead screw rotates reversely, it can drive the sleeve block to rotate reversely, so that the sliding rod drives the clamping plate to be clamped with the clamping block, making the rolling plate and the limiting ring into a whole. Under the action of the reciprocating lead screw and the sleeve block, the limiting ring and the rolling plate move towards the electromagnetic heater direction, and the waste plastic inside the electromagnetic heater and the inner side of the rolling plate is extruded.

[0011] Preferably, the outer wall of the sliding ring is slidably arranged with the outer wall of the arc plate, and the outer wall of the limiting rod is slidably arranged inside the electromagnetic heater. Under its limitation, when the limiting ring moves downward, the limiting rod drives the fixing block to move downward accordingly, so that the sliding ring no longer contacts and presses against the outer wall of the arc plate, and the arc plate is in an open state to carry out the feeding work.

[0012] Preferably, the number of the arc plates is eight, and they are distributed circumferentially around the center of the reciprocating lead screw. The arc plates gather into a conical shape. Under its limitation, when the sliding ring no longer contacts and presses against the arc plate, the arc plate is in an open state to carry out the feeding work.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The waste plastic decomposition heater has a decomposition component as one of its parts. When waste plastic needs to be decomposed and heated, it is added into the barrel body. The motor is started, and the reciprocating lead screw fixedly installed at its output end rotates accordingly. When the reciprocating lead screw rotates forward, the inclined surface of its clamping plate contacts and presses against the inclined surface of the clamping block, causing the clamping plate to slide on the outer wall of the sliding rod and compress the spring, so that the clamping plate and the clamping block are not engaged. Under its restriction, the reciprocating lead screw can drive the sleeve block to rotate, and the rolling plate fixedly installed on the top surface of the sleeve block rotates accordingly. When the reciprocating lead screw rotates in reverse, it causes the sleeve block to drive the end of the clamping plate away from the inclined surface to engage with the clamping block, and the limiting rod fixedly installed on the top surface of the limiting ring slides inside the electromagnetic heater. Under its restriction, rotating the reciprocating lead screw can drive the limiting ring and the rolling plate rotatably connected inside it to move upward, pushing the waste plastic on the top surface of the rolling plate towards the bottom of the electromagnetic heater. The electromagnetic heater is started. At this time, the reciprocating lead screw rotates forward, driving the rolling plate to rotate accordingly, and rolling the waste plastic between the rolling plate and the inner side of the electromagnetic heater to make its extrusion more uniform, so as to improve the decomposition and heating effect of the waste plastic. When the decomposition is completed, the second electromagnetic valve inside the rolling plate is opened for discharging work, and the material is discharged through the negative pressure suction pump (the barrel body, support legs, negative pressure suction pump, PLC controller, electromagnetic heater, first electromagnetic valve, and second electromagnetic valve are existing public technologies in the comparative document, so their structures are not fully described in this case).

[0015] 2. The waste plastic decomposition heater has a feeding component as one of its parts. When waste plastic needs to be fed, the decomposed plastic inside the electromagnetic heater and the rolling plate is unloaded. The second electromagnetic valve inside the rolling plate is closed. At this time, the reciprocating lead screw is started to rotate in reverse, driving the limiting ring and the rolling plate to move downward, causing the limiting rod fixedly installed on the top surface of the limiting ring to slide inside the electromagnetic heater, and the limiting rod drives the fixed block to move downward accordingly. The sliding ring fixedly installed on the outer wall of the fixed block no longer contacts and presses against the outer wall of the arc plate. Under the action of gravity, the arc plate hinged to the bottom of the fixed ring is in an open state, and the waste plastic inside it is fed. The first electromagnetic valve inside the electromagnetic heater is opened to feed the waste plastic between the rolling plate and the electromagnetic heater. At this time, the reciprocating lead screw is started to rotate in reverse again, moving the limiting ring and the rolling plate towards the electromagnetic heater. The sliding ring slides and presses against the outer wall of the arc plate to close the arc plate, and this process is repeated to carry out the decomposition and heating work on the waste plastic.

Detailed implementation manners

[0023] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the following describes the detailed implementation manners of the present utility model with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] A preferred embodiment of a waste plastic decomposition heater provided by the present utility model is as Figures 1 to 6 shown: A waste plastic decomposition heater includes a barrel body 1;

[0026] Support legs 2 are fixedly installed at the bottom of the barrel body 1;

[0027] A negative pressure suction pump 3 is arranged at the bottom of the barrel body 1;

[0028] A PLC controller 4 is arranged at the top of the barrel body 1;

[0029] An electromagnetic heater 6 is fixedly installed inside the barrel body 1;

[0030] A first electromagnetic valve 7 is arranged inside the electromagnetic heater 6;

[0031] A second electromagnetic valve 8 is arranged below the first electromagnetic valve 7;

[0032] and a processing component 5 arranged inside the barrel body 1. The processing component 5 includes a decomposition component 51 arranged inside the barrel body 1. The decomposition component 51 includes a support frame 511 fixedly installed on the top surface of the barrel body 1. One end of the support frame 511 away from the top surface of the barrel body 1 is fixedly installed with a motor 512. The output end of the motor 512 is fixedly installed with a reciprocating lead screw 513. A sleeve block 514 is sleeved on the outer wall of the reciprocating lead screw 513. A rolling plate 515 is fixedly installed on the top surface of the sleeve block 514. A sliding rod 516 is fixedly installed on the outer wall of the sleeve block 514. A spring 517 is sleeved on the outer wall of the sliding rod 516. A clamping plate 518 is slidably arranged on the outer wall of the sliding rod 516. A limiting ring 520 is rotatably connected to the outer wall of the rolling plate 515. A clamping block 519 is fixedly installed on the inner wall of the limiting ring 520. One end of the reciprocating lead screw 513 away from the motor 512 is rotatably connected to a cross plate 521.

[0033] In this embodiment, when it is necessary to decompose and heat waste plastics, add them into the barrel body 1, start the motor 512, and the reciprocating lead screw 513 fixedly installed at its output end rotates accordingly. When the reciprocating lead screw 513 rotates forward, the inclined surfaces of its clamping plate 518 and the clamping block 519 come into contact and squeeze, causing the clamping plate 518 to slide on the outer wall of the sliding rod 516 and compress the spring 517, so that the clamping plate 518 and the clamping block 519 are not clamped. Under its restriction, the reciprocating lead screw 513 can drive the sleeve block 514 to rotate, and the rolling plate 515 fixedly installed on the top surface of the sleeve block 514 rotates accordingly. When the reciprocating lead screw 513 rotates reversely, the sleeve block 514 drives the end of the clamping plate 518 away from the inclined surface to be clamped with the clamping block 519, and the limiting rod 531 fixedly installed on the top surface of the limiting ring 520 is slidably arranged inside the electromagnetic heater 6. Under its restriction, rotating the reciprocating lead screw 513 can drive the limiting ring 520 and the rolling plate 515 rotatably connected inside it to move upward, pushing the waste plastics on the top surface of the rolling plate 515 towards the bottom of the electromagnetic heater 6. Start the electromagnetic heater 6. At this time, rotate the reciprocating lead screw 513 forward, and it drives the rolling plate 515 to rotate accordingly, rolling the waste plastics between the rolling plate 515 and the inner side of the electromagnetic heater 6 to make their extrusion more uniform, so as to improve the decomposition and heating effect of the waste plastics. When the decomposition is completed, open the second electromagnetic valve 8 inside the rolling plate 515 for discharging work, and then discharge the material through the negative pressure suction pump 3 (the barrel body 1, the support legs 2, the negative pressure suction pump 3, the PLC controller 4, the electromagnetic heater 6, the first electromagnetic valve 7, and the second electromagnetic valve 8 are existing publicly known technologies in the comparative document, so their structures are not fully described in this case).

[0034] Further, the end of the clamping plate 518 is provided with an inclined surface, the outer wall of the clamping block 519 is provided with an inclined surface, and the rolling plate 515 is rotatably connected to the inner wall of the limiting ring 520. Under its limitation, when the reciprocating lead screw 513 rotates forward, the slide bar 516 fixedly installed on the outer wall of the sleeve block 514 rotates accordingly. The clamping plate 518 sleeved on the outer wall of the slide bar 516 is in contact with and extruded by the inclined surface of the limiting ring 520 fixedly installed on the inner wall of the limiting ring 520, so that the clamping plate 518 and the clamping block 519 are no longer clamped, so that the sleeve block 514 can drive the rolling plate 515 fixedly installed on its top surface to rotate accordingly.

[0035] Furthermore, the top surface of the limiting ring 520 is fixedly installed with a limiting rod 531, and the outer wall of the limiting rod 531 is slidably arranged inside the electromagnetic heater 6. Under its limitation, when the reciprocating lead screw 513 rotates reversely, it can drive the sleeve block 514 to rotate reversely, so that the slide bar 516 drives the clamping plate 518 to be clamped with the clamping block 519, making the rolling plate 515 and the limiting ring 520 into a whole. Under the action of the reciprocating lead screw 513 and the sleeve block 514, the limiting ring 520 and the rolling plate 515 move towards the electromagnetic heater 6, extruding the waste plastic inside the electromagnetic heater 6 and the rolling plate 515.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, a preferred embodiment of a waste plastic decomposition heater provided by the present utility model is as Figures 1 to 6 shown: The feeding assembly 53 includes a limiting rod 531 fixedly installed on the top surface of the limiting ring 520. One end of the limiting rod 531 away from the limiting ring 520 is fixedly installed with a fixing block 532. The outer wall of the fixing block 532 is fixedly installed with a sliding ring 533. The inner wall of the barrel body 1 is fixedly installed with a fixing ring 534. The bottom of the fixing ring 534 is hinged with an arc plate 535.

[0038] In this embodiment, when it is necessary to feed waste plastics, the electromagnetic heater 6 is used to unload the plastics that have been disassembled inside the rolling plate 515. Then, the second electromagnetic valve 8 inside the rolling plate 515 is closed. At this time, the reciprocating lead screw 513 is started to reverse, driving the limiting ring 520 and the rolling plate 515 to move downward, so that the limiting rod 531 fixedly installed on the top surface of the limiting ring 520 slides inside the electromagnetic heater 6, causing the limiting rod 531 to drive the fixed block 532 to move downward accordingly. The sliding ring 533 fixedly installed on the outer wall of the fixed block 532 no longer contacts and presses against the outer wall of the arc plate 535. Under the action of gravity, the arc plate 535 hinged to the bottom of the fixed ring 534 is in an open state, and the waste plastics inside it are fed. The first electromagnetic valve 7 inside the electromagnetic heater 6 is opened, and the waste plastics are fed between the rolling plate 515 and the electromagnetic heater 6. At this time, the reciprocating lead screw 513 is started to reverse again, moving the limiting ring 520 and the rolling plate 515 towards the electromagnetic heater 6. The sliding ring 533 slides and presses against the outer wall of the arc plate 535, closing the arc plate 535. This process is repeated to decompose and heat the waste plastics.

[0039] Furthermore, the outer wall of the sliding ring 533 is slidably arranged with the outer wall of the arc plate 535, and the outer wall of the limiting rod 531 is slidably arranged inside the electromagnetic heater 6. Under this limitation, when the limiting ring 520 moves downward, the limiting rod 531 drives the fixed block 532 to move downward accordingly, so that the sliding ring 533 no longer contacts and presses against the outer wall of the arc plate 535, and the arc plate 535 is in an open state for feeding work.

[0040] In addition, there are eight arc plates 535, which are distributed circumferentially around the center of the reciprocating lead screw 513. The arc plates 535 converge into a conical shape. Under this limitation, when the sliding ring 533 no longer contacts and presses against the arc plate 535, the arc plate 535 is in an open state for feeding work.

[0041] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be used alone according to actual needs or combined with multiple features. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
