Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic production equipment technology, and in particular to a drying device for PVC plastic production. Background Technology
[0002] PVC plastic is a synthetic polymer plastic widely used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery and other plastic products. In order to improve the quality of plastic products, the raw materials are generally processed into plastic granules. Plastic granules are easily exposed to moisture in the air, so drying equipment is needed to dry the plastic granules before they are processed into plastic products.
[0003] In existing drying equipment, plastic granules are typically fed into the equipment through a feed pipe located at the top and discharged through a discharge pipe located at the bottom after drying. Because the discharge pipe is located at the bottom of the equipment, the plastic granules tend to enter the discharge pipe under the influence of gravity, preventing them from being dried properly and hindering the thorough drying of the plastic granules. Utility Model Content
[0004] In view of this, the present invention provides a drying device for PVC plastic production, the main technical problem to be solved is: the problem of being unable to dry plastic particles in the discharge pipe.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for PVC plastic production, comprising a base, a drying barrel fixedly connected to the top of the base, a stirring device fixedly connected to the right side of the drying barrel, a fan fixedly connected to the top of the drying barrel, a fixing sleeve fixedly connected to the left side of the outer side of the drying barrel, a rotating shell movably connected to the left side of the drying barrel, the rotating shell comprising a housing movably connected to the left side of the drying barrel, a through hole provided on the left side of the housing, a material cylinder fixedly connected to the top of the housing, a sealing cover placed on the top of the material cylinder, a sealing sleeve fixedly connected to the lower outer side of the sealing cover, and slots provided on the upper and lower sides of the right side of the outer side of the housing.
[0006] By adopting the above technical solution, pulling the insert upwards allows it to leave the slot, enabling the shell to rotate on the left side of the drying chamber. This rotation allows the opening of the material cylinder to face upwards, allowing plastic granules to enter the drying chamber for drying. After drying, the opening of the material cylinder is turned downwards to allow the plastic granules to be discharged. This prevents the plastic granules from remaining inside the material cylinder during drying, which could lead to insufficient drying. Furthermore, after releasing the insert, the spring causes it to move downwards and contact the shell. Rotating the shell allows the insert to be inserted into the slot, thus fixing the position of the rotating shell and facilitating the stable pouring and discharge of plastic granules.
[0007] As a further description of the above technical solution: the base includes a seat body, a rotating cylinder is fixedly connected to the left side of the top of the seat body, a rotating column is movably connected inside the rotating cylinder, a top plate is fixedly connected to the outside of the rotating column, a fixing plate is fixedly connected to the lower part of the top plate, the fixing plate has an inclined groove inside, a guide column is fixedly connected to the inside of the seat body, a slider is movably connected to the outside of the guide column, a supporting motor is fixedly connected to the right side of the seat body, a stud is fixedly connected to the output end of the supporting motor, a screw block is threadedly connected to the outside of the stud, and a rotating cylinder is movably connected between the screw block and the slider.
[0008] By adopting the above technical solution, the stud can be rotated by starting the support motor, and the screw block can move back and forth by the forward and reverse rotation of the stud. This drives the rotating cylinder, which in turn drives the fixed plate to rotate the top plate around the rotating column as the axis. This allows the drying barrel to tilt, making it easier to discharge the dried plastic granules.
[0009] As a further description of the above technical solution: the drying barrel includes a support plate fixedly connected to the top of the top plate, the top of the support plate is fixedly connected to the barrel body, and the left side of the barrel body is provided with a rotating groove.
[0010] By adopting the above technical solution, the rotating groove is used for the rotation of the shell.
[0011] As a further description of the above technical solution: the stirring device includes a stirring motor fixedly connected to the right side of the tank body, the output end of the stirring motor is fixedly connected to a rotating shaft, and a stirring plate is fixedly connected to the outside of the rotating shaft.
[0012] By adopting the above technical solution, the stirring motor is started so that the rotating shaft can drive the stirring plate to stir the plastic particles, so that the plastic particles can fully contact the hot air and the drying efficiency is higher.
[0013] As a further description of the above technical solution: the fan includes a fixed shell fixedly connected to the top of the barrel, a dustproof plate fixedly connected to the top of the fixed shell, a support column fixedly connected to the upper inner side of the fixed shell, a rotating motor fixedly connected to the inner side of the support column, a fan blade fixedly connected to the output end of the rotating motor, and a heating wire fixedly connected to the middle of the inner side of the fixed shell.
[0014] By adopting the above technical solution, the fan blades can be rotated by starting the rotating motor, and the fan can generate air and blow it into the drying barrel. Furthermore, by energizing the heating wire, the fan can blow in hot air, which can dry the plastic particles.
[0015] As a further description of the above technical solution: the fixed sleeve includes a sleeve body fixedly connected to the left side of the outer side of the barrel body, a cylinder body fixedly connected to the top of the sleeve body, an insert post movably connected inside the cylinder body, and a spring fixedly connected between the sleeve body and the insert post.
[0016] By adopting the above technical solution, the spring is in a compressed state without external force, so that the insertion post can be stably placed in the slot.
[0017] By employing the above technical solution, the drying equipment for PVC plastic production of this utility model has at least the following beneficial effects:
[0018] Compared with existing technologies, this drying equipment for PVC plastic production, by incorporating a rotating shell, facilitates thorough drying of plastic granules. By pulling the insert upwards, the insert can disengage from the slot, allowing the shell to rotate on the left side of the drying drum. This rotation causes the opening of the material cylinder to face upwards, allowing the plastic granules to enter the drying drum for drying. Conversely, by turning the opening of the material cylinder downwards, the dried plastic granules can be discharged, ensuring that the plastic granules do not remain inside the material cylinder during drying, thus preventing incomplete drying.

Detailed Implementation
[0026] Reference Figure 1-5This utility model provides a drying device for PVC plastic production: It includes a base 1, a drying drum 2 fixedly connected to the top of the base 1, a stirring device 3 fixedly connected to the right side of the drying drum 2, a fan 4 fixedly connected to the top of the drying drum 2, a fixing sleeve 5 fixedly connected to the left side of the outer side of the drying drum 2, and a rotating shell 6 movably connected to the left side of the drying drum 2. The rotating shell 6 includes a housing 601 movably connected to the left side of the drying drum 2, the housing 601 being rotatable on the left side of the drying drum 2, and a through hole 60 on the left side of the housing 601. 2. The through hole 602 is used to discharge the water vapor evaporated during drying. A material cylinder 603 is fixedly connected to the top of the shell 601. The material cylinder 603 is used for pouring and discharging plastic granules. A sealing cover 605 is placed on the top of the material cylinder 603. A sealing sleeve 604 is fixedly connected to the lower outer side of the sealing cover 605. The inner side of the material cylinder 603 is provided with a groove that matches the sealing sleeve 604. By placing the sealing cover 605 on the top of the material cylinder 603 and compressing it, the sealing sleeve 604 can be deformed, thereby allowing the sealing sleeve 604 to... 04 can enter the groove in the inner wall of the barrel 603, thereby fixing the sealing cover 605. The upper and lower sides of the outer right side of the shell 601 are provided with slots 606 for inserting the insert 503. By pulling the insert 503 upward, the insert 503 can be removed from the slot 606, thereby allowing the shell 601 to rotate on the left side of the drying barrel 2. By rotating, the opening of the barrel 603 can face upward, allowing the plastic granules to enter the drying barrel 2 through the barrel 603 for drying. After drying, the opening of the barrel 603 can be turned downward to allow the plastic granules to be discharged, so that the plastic granules will not be inside the barrel 603 during drying, resulting in insufficient drying. After releasing the insert 503, the spring 504 causes the insert 503 to move downward and contact the shell 601. By rotating the shell 601, the insert 503 can be inserted into the slot 606, thereby fixing the position of the rotating shell 6, which facilitates the stable pouring and discharge of plastic granules.
[0027] Furthermore, the base 1 includes a seat body 101. A rotating cylinder 102 is fixedly connected to the left side of the top of the seat body 101. A rotating column 112 is movably connected inside the rotating cylinder 102. The rotating cylinder 102 and the rotating column 112 can rotate relative to each other, allowing the top plate 103 to rotate relative to the seat body 101. The top plate 103 is fixedly connected to the outer side of the rotating column 112. A fixing plate 105 is fixedly connected to the lower part of the top plate 103. The fixing plate 105 has an inclined groove 106 inside, which is set at an angle and gradually decreases in height from left to right. A guide post 109 is fixedly connected to the inner side of the seat body 101. A slider 110 is movably connected to the outer side of the guide post 109, allowing the slider 110 to move outside the guide post 109. A support motor 1 is fixedly connected to the right side of the seat body 101. 08. A stud 107 is fixedly connected to the output end of the supporting motor 108. A screw block 104 is threadedly connected to the outside of the stud 107. A rotating cylinder 111 is movably connected between the screw block 104 and the slider 110. The rotating cylinder 111 can rotate between the screw block 104 and the slider 110. The rotating cylinder 111 is located in the inclined groove 106, and the top of the rotating cylinder 111 is in contact with the fixed plate 105. By starting the supporting motor 108, the stud 107 can rotate. The forward and reverse rotation of the stud 107 causes the screw block 104 to move back and forth, thereby driving the rotating cylinder 111 so that the fixed plate 105 can drive the top plate 103 to rotate around the rotating column 112 as the axis, thereby allowing the drying barrel 2 to tilt, which facilitates the discharge of the dried plastic granules.
[0028] Furthermore, the drying barrel 2 includes a support plate 203 fixedly connected to the top of the top plate 103. The top of the support plate 203 is fixedly connected to the barrel body 201. A rotating groove 202 is provided on the left side of the barrel body 201, and the rotating groove 202 is used for the rotation of the shell 601.
[0029] Furthermore, the stirring device 3 includes a stirring motor 301 fixedly connected to the right side of the barrel 201. The output end of the stirring motor 301 is fixedly connected to a rotating shaft 303, and a stirring plate 302 is fixedly connected to the outside of the rotating shaft 303. By starting the stirring motor 301, the rotating shaft 303 can drive the stirring plate 302 to stir the plastic particles, so that the plastic particles can fully contact the hot air, making the drying efficiency higher.
[0030] Furthermore, the blower 4 includes a fixed shell 401 fixedly connected to the top of the barrel 201. A dustproof plate 403 is fixedly connected to the top of the fixed shell 401 for dust prevention. A support column 404 is fixedly connected to the upper inner side of the fixed shell 401. A rotating motor 402 is fixedly connected to the inner side of the support column 404. A fan blade 406 is fixedly connected to the output end of the rotating motor 402. A heating wire 405 is fixedly connected to the middle of the inner side of the fixed shell 401. By starting the rotating motor 402, the fan blade 406 can rotate, thereby generating air and blowing it into the drying barrel 2. By energizing the heating wire 405, the blower 4 can blow hot air, which can dry the plastic particles.
[0031] Furthermore, the fixing sleeve 5 includes a sleeve body 501 fixedly connected to the left side of the outer side of the barrel body 201. A cylinder body 502 is fixedly connected to the top of the sleeve body 501. An insert post 503 is movably connected inside the cylinder body 502. The insert post 503 can be raised and lowered inside the cylinder body 502. A spring 504 is fixedly connected between the sleeve body 501 and the insert post 503. The spring 504 is in a compressed state when there is no external force, so that the insert post 503 can be stably placed in the slot 606.
[0032] Working principle: During use, open the sealing cover 605 and pull the insert 503 upwards to disengage it from the slot 606. This allows the housing 601 to rotate on the left side of the drying chamber 2. The rotation causes the opening of the material cylinder 603 to face upwards, allowing the plastic granules to enter the drying chamber 2 through the material cylinder 603 for drying. During drying, close the sealing cover 605 and start the fan 4 to allow hot air to enter the chamber 201. Simultaneously, start the stirring device 3 to agitate the plastic granules, ensuring they are fully in contact with the hot air for better drying. After drying is complete, remove the sealing cover 605 and turn the opening of the material cylinder 603 downwards. The start of the support motor 108 enables the top plate 103 to rotate around the rotating column 112, thereby tilting the barrel 201. The start of the stirring device 3 stirs the plastic granules, allowing them to pass smoothly through the material cylinder 603 under the influence of gravity and the stirring plate 302. This ensures that the plastic granules do not remain inside the material cylinder 603 during drying, preventing insufficient drying. After the insertion post 503 is released, the spring 504 causes the insertion post 503 to move downwards and contact the housing 601. Rotating the housing 601 allows the insertion post 503 to be inserted into the slot 606, thus fixing the position of the rotating shell 6 and facilitating the stable pouring and discharge of plastic granules.
