Description

Technical Field

[0001] The utility model relates to the technical field of plastic pellet processing, in particular to a plastic pellet drying device. Background Art

[0002] Plastic pellets, also known as plastic granules, are granular materials primarily composed of high molecular weight polymers. They are primarily made from petrochemical products through a series of processing steps. Common raw materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS). These materials are polymerized to form high molecular weight chains, which are then processed into plastic pellets through processes such as granulation.

The plastic particle dust removal and drying device, through the cooperation of the drying and tumbling mechanism and the dust removal assembly, can uniformly tumble the plastic particles, thereby uniformly heating the plastic particles during drying. The tumbling of the plastic particles simultaneously collects and processes dust contained in the plastic particles, thereby improving the dust removal and drying efficiency of the plastic particles and enhancing the performance of the processing equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment: a plastic pellet drying device, including a supporting leg 1, the top of the supporting leg 1 is fixedly connected to a drying box 2, the drying box 2 is used to dry the plastic pellets, and the bottom end of the drying box 2 is provided with a dust suction plate and a dust collector, and the right end is provided with a discharge port, the front end inner wall of the drying box 2 is rotatably connected to a baffle door 3, the baffle door 3 can be closed or opened when needed, and the right end of the drying box 2 is provided with a dust reduction mechanism 4; the dust reduction mechanism 4 is provided to prevent dust from flying when the baffle door 3 is opened.

[0033] Reference Figure 2-Figure 3 The dust reduction mechanism 4 includes a motor 401, and the outer arc surface of the output end of the motor 401 is connected to the rotating seat 403 through a belt 402. The rotation of the output end of the motor 401 drives the belt 402 to rotate, so that the rotating seat 403 swings, thereby achieving a better dust reduction effect. The right inner side wall of the drying box 2 is fixedly connected to a support plate 405, and the inner wall of the support plate 405 is rotatably connected to a water storage column 410. The support plate 405 is provided with two groups, so as to provide support for the water storage column 410. The outer wall of the water storage column 410 is fixedly connected to a support seat 407, which is composed of two groups of long plates and a group of cylinders. The long plate surface is fixed to the water storage column 410, and the left end of the rotating seat 403 is fixedly connected to a connecting plate 408. 3 rotates and drives the connecting plate 408 to rotate. The inner wall of the top end of the connecting plate 408 is rotatably connected to the connecting column 409. The left end of the connecting column 409 is a circular surface. The inner wall of the water storage column 410 is threadedly connected to the water pipe 404. The water pipe 404 can replenish the dust suppression water. The inner wall of the left end of the drying box 2 is fixedly connected to the hot air blower 5. The hot air blower 5 is a prior art and can dry relatively moist plastic particles. The inner wall of the drying box 2 is fixedly connected to the sieve plate 6. The sieve plate 6 can collect dust to the bottom. The bottom end of the sieve plate 6 is provided with a cleaning mechanism 7, which can dredge the sieve plate 6 through the cleaning mechanism 7. The output end of the motor 401 is provided with a stirring component, which can break up the plastic particles to avoid accumulation of plastic particles.

[0034] Reference Figure 2-Figure 3The left end of the motor 401 is fixedly connected to the right end of the drying box 2, and the drying box 2 can support the motor 401. The stirring assembly includes a rotating column 411, and the right end of the rotating column 411 is rotatably connected to the right inner wall of the drying box 2. The right end of the rotating column 411 is fixedly connected to the output end of the motor 401, and the rotating column 411 is driven to rotate through the output end of the motor 401, and the right inner wall of the drying box 2 can provide support for the rotating column 411. The outer arc surface of the rotating column 411 is fixedly connected to the stirring rod 412, and the movement trajectories of the two are consistent. The outer wall of the rotating seat 403 is rotatably connected to the inner wall of the right end of the drying box 2, and the rotating setting avoids motion interference.

[0035] Reference Figure 2-Figure 3 The inner side wall of the circular ring of the connecting column 409 is slidably connected to the outer arc surface of the support seat 407. The sliding of the two can make the support seat 407 swing up and down, so that the spraying and dust reduction effect is better. The outer wall of the water pipe 404 contacts the right inner wall of the drying box 2. The contact between the two can achieve the installation purpose. The end of the water pipe 404 close to the water storage column 410 is in the shape of a telescopic hose. The telescopic setting can prevent the water pipe 404 from falling off when the support seat 407 rotates. The right end of the water pipe 404 can be connected to the corresponding water tank through a thread. The bottom end of the water storage column 410 is fixedly connected to the nozzle 406, which can guide the dust reduction water.

[0036] Reference Figure 1 and Figure 4 The cleaning mechanism 7 includes an elastic telescopic rod 702, which is formed by two sets of rods connected to each other, and can slide relative to each other to change its overall length. In addition, the elastic telescopic rod 702 has a built-in spring, which makes it have a certain elasticity. The top of the elastic telescopic rod 702 is fixedly connected to the bottom end of the sieve plate 6, and the bottom end of the elastic telescopic rod 702 is fixedly connected to the fixed plate 701. The elasticity of the elastic telescopic rod 702 makes the fixed plate 701 have a reset and cleaning effect, and the top of the fixed plate 701 is fixedly connected to the cleaning Column 704, the sieve holes of the sieve plate 6 are cleared and cleaned through the cleaning column 704, and a guide groove 703 is provided at the bottom end of the fixed plate 701. The guide groove 703 can guide the dust to facilitate discharge. The top end of the cleaning column 704 contacts the inner side wall of the sieve plate 6, and the two contact each other to clean the sieve plate 6. The top end of the support seat 407 contacts the bottom end of the fixed plate 701, and the two contact each other so that the fixed plate 701 moves upward. When the two are not in contact, the elasticity of the elastic telescopic rod 702 causes the support seat 407 to reset.

[0037] Working principle: When it is necessary to perform dust reduction operation on the flying dust inside the drying box 2, connect the right end of the water pipe 404 to the corresponding water tank, then start the hot air blower 5 and the motor 401, and the output end of the motor 401 rotates to drive the stirring rod 412 to rotate for stirring and breaking up the particles. When breaking up the particles, the dust falls off from the surface of the plastic particles, and the rotation of the output end of the motor 401 drives the belt 402 to move, so that the rotating seat 403 drives the connecting plate 408 and the connecting column 409 to rotate. Since the connection relationship between the connecting column 409 and the support seat 407 is sliding, the support seat 407 will swing around the water storage column 410 as the center, causing the nozzle 406 to swing, and the purpose is achieved by the contact between the dust reduction water and the dust, and the up and down swinging of the nozzle 406 can make the dust reduction water spraying range wider.

[0038] When the support seat 407 swings upward, it will contact the bottom end of the fixed plate 701. When the two are in contact, the fixed plate 701 will drive the cleaning column 704 to move upward, so that the cleaning column 704 contacts the sieve holes of the sieve plate 6 to achieve the cleaning purpose. When the support seat 407 is not in contact with the fixed plate 701, the elasticity of the elastic telescopic rod 702 causes the fixed plate 701 to reset and move downward, thereby avoiding manual cleaning and achieving the purpose of saving time and effort. The dust will pass through the sieve holes and guide grooves 703 on the sieve plate 6, and then move to the bottom of the dust collection plate for collection.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
