Description

Technical Field

[0001] This utility model relates to the field of PVC material processing technology, specifically to a PVC powder dehumidification device. Background Technology

[0002] PVC, or polyvinyl chloride, is one of the world's most produced plastic products. It is inexpensive and widely used. Dehumidification is required during the processing of PVC materials.

[0003] Patent CN218700437U discloses a PVC powder dehumidification device, including a housing. An exhaust pipe is fixedly connected to the top of the housing, a filter screen is fixedly connected to the inner wall of the exhaust pipe, a fixing frame is fixedly connected to the inner top wall of the housing, a heating element is fixedly connected to one side of the fixing frame, and a discharge pipe is fixedly connected to the bottom of the fixing frame. A discharge valve is fixedly connected to the outer wall of the discharge pipe. This PVC powder dehumidification device, through its housing, exhaust pipe, filter screen, fixing frame, heating element, humidity detection device, hot air blower body, ventilation pipe, and nozzle, effectively dehumidifies the PVC powder. Therefore, when using this dehumidification device to dehumidify the PVC powder during production and processing, it effectively removes moisture from the powder, reducing work pressure, meeting work needs, improving the efficiency of the dehumidification device, and bringing convenience to workers.

[0004] When using this patent, it should be combined with the patent's... Figure 1 It is known that because the bottom of its fixed frame is flat, material discharge is inconvenient and the material is not easy to discharge. It also requires manual cleaning, making it inconvenient to use. In addition, when the material of this patent dries inside the fixed frame, the material is in a static dehumidification state, which results in low dehumidification efficiency. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a PVC powder dehumidification device that facilitates material discharge and improves dehumidification efficiency.

[0006] This utility model is achieved through the following technical solution: a PVC powder dehumidification device, including a box body and a base, with two opposing supports fixed on the base. A central shaft is fixed to the left and right outer walls of the box body. The box body is rotatably connected to the two supports through the two central shafts. A first driving mechanism is provided on the base to drive one of the central shafts to rotate. A first square cone hopper and a dehumidification component are fixed to the upper and lower outer walls of the box body, respectively. The inner cavity of the box body and the inner cavity of the first square cone hopper are connected.

[0007] This solution involves rotating the housing around its central axis. When the first conical hopper is above the housing, powder can be added through it, and the powder is dehumidified by the dehumidification assembly below. The resulting moisture is then directly discharged through the first conical hopper. After dehumidification, the housing rotates 180° via a first drive mechanism, moving the first conical hopper to the bottom of the housing. At this point, the powder is also guided and discharged through the first conical hopper. Compared to existing technologies, this method provides smoother, less labor-intensive discharge and is more convenient to use.

[0008] As an optimization, the first square conical hopper and the box body are integrally formed. This optimized design facilitates processing.

[0009] As an optimization, a slide gate valve is fixedly connected to the port of the first conical hopper, and a second conical hopper is fixedly connected to the end of the slide gate valve away from the first conical hopper. This optimized solution facilitates the control of powder discharge through the slide gate valve and facilitates the feeding of material through the second conical hopper.

[0010] As an optimization, the dehumidification assembly of the housing includes a hot air blower fixed to the outer wall of the housing, with a conveying main pipe fixed to the output end of the hot air blower. Multiple nozzles are axially distributed and fixed to the inner wall of the housing, and each nozzle is connected to the conveying main pipe via a branch pipe. This optimized solution delivers hot air to the multiple nozzles via the hot air blower, thereby drying and dehumidifying the powder material and improving dehumidification efficiency.

[0011] As an optimization, the first drive mechanism includes a driven gear fixed to one of the central shafts and a first motor. A driving gear is fixed to the output end of the first motor, and the driving gear meshes with the driven gear. This optimized solution uses the first motor to drive the driving gear to rotate, which in turn drives the driven gear to rotate, causing the central shaft to rotate, and thus realizing the rotation of the housing. Using a drive gear and driven gear transmission method allows for more accurate control of the housing's rotation angle.

[0012] As an optimization, a stirring shaft is mounted on another central shaft, rotatably connected to the central shaft. One end of the stirring shaft extends into the interior of the housing and is fixedly connected to multiple stirring rods. A second drive mechanism for driving the stirring shaft to rotate is provided on the base. This optimized solution uses the stirring shaft to stir the powder, allowing it to tumble and move during dehumidification, achieving dynamic dehumidification and further improving dehumidification efficiency and effect. The rotatable connection between the stirring shaft and the central shaft allows the housing and the stirring shaft to rotate independently without affecting each other, resulting in a stable and optimized structure.

[0013] As an optimization, the second drive mechanism includes a driven pulley fixed to the other end of the stirring shaft, and a second motor. A driving pulley is fixed to the output end of the second motor, and the driving pulley and the driven pulley are connected by a belt drive. This optimized solution drives the rotation of the driving pulley via the second motor, which in turn drives the rotation of the driven pulley via the belt, thereby achieving the rotation of the stirring shaft.

[0014] The beneficial effects of this utility model are as follows: When the first conical hopper is located above the box body, powder can be added into the box body through the first conical hopper, and the powder can be dehumidified by the dehumidification component below. The moisture generated during dehumidification can be directly discharged through the first conical hopper. After dehumidification is completed, the box body is driven to rotate 180° by the first drive mechanism, so that the first conical hopper rotates to the bottom of the box body. At this time, the powder is also discharged through the guide of the first conical hopper. Compared with the prior art, the discharge is smoother and less labor-intensive, and it is more convenient to use.

[0015] The powder is stirred by the stirring shaft, allowing it to tumble and move during dehumidification, achieving dynamic dehumidification and further improving dehumidification efficiency and effect. The stirring shaft and the central shaft are rotatably connected, allowing the housing and the stirring shaft to rotate independently without affecting each other, resulting in an optimized and stable structure.

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] like Figures 1-5 As shown, a PVC powder dehumidification device includes a housing 3 and a base 1. Two opposing supports 2 are fixed on the base 1. A central shaft 7 is fixed on the left and right outer walls of the housing 3. The housing 3 is rotatably connected to the two supports 2 through the two central shafts 7. A first driving mechanism 8 is provided on the base 1 to drive one of the central shafts 7 to rotate. A first square cone hopper 4 and a dehumidification component 11 are fixed on the upper and lower outer walls of the housing 3, respectively. The inner cavity of the housing 3 is connected to the inner cavity of the first square cone hopper 4.

[0025] In this embodiment, the bracket 2 is a triangular bracket, which supports the box 3, resulting in higher stability. Bearing seats 21 are fixedly connected to the top of each bracket 2, and the central shafts 7 on both sides of the box 3 are rotatably connected to the bearing seats 21.

[0026] The first drive mechanism 8 includes a driven gear 81 fixedly connected to one of the central shafts 7, and a first motor 83. A driving gear 83 is fixedly connected to the output end of the first motor 83, and the driving gear 83 meshes with the driven gear 81. In this embodiment, the first motor 81 and the bracket 2 are fixedly connected. The first motor 81 drives the driving gear 83 to rotate, which in turn drives the driven gear 81 to rotate, thereby causing the central shaft 7 to rotate, and thus realizing the rotation of the housing 3. Using a drive gear and driven gear transmission method allows for more accurate control of the housing's rotation angle.

[0027] In this embodiment, the box 3 is a rectangular box, and the first square cone hopper 4 and the box 3 are integrally formed, which is convenient for processing.

[0028] A slide gate valve 5 is fixedly connected to one end of the first conical hopper 4, and a second conical hopper 6 is fixedly connected to the end of the slide gate valve 5 away from the first conical hopper 4. In this embodiment, one end of the slide gate valve 5 is fixedly connected to the smaller diameter end of the first conical hopper 4. The size of the second conical hopper 6 is smaller than that of the first conical hopper 4, and the smaller diameter end of the second conical hopper 6 is fixedly connected to the other end of the slide gate valve 5. The slide gate valve 5 facilitates the control of powder discharge, and the second conical hopper 6 facilitates the addition of materials into the housing 3.

[0029] The dehumidification assembly 11 includes a hot air blower 111 fixed to the outer wall of the housing 3. A conveying main pipe 112 is fixedly connected to the output end of the hot air blower 111, and the end of the conveying main pipe 12 away from the hot air blower 111 is closed. Multiple nozzles 114 are axially distributed and fixed to the inner wall of the housing 3, and each nozzle 114 is connected to the conveying main pipe 112 via a branch pipe 113. Hot air is supplied to the multiple nozzles 114 by the hot air blower 111, and the multiple nozzles 114 dry and dehumidify the powder, thereby improving dehumidification efficiency.

[0030] Preferably, a hygrometer 12 is also fixed on the box body 3 to monitor the humidity of the material inside the box body 3.

[0031] Another central shaft 7 is fitted with a stirring shaft 9, which is coaxial with the central shaft 7 and rotatably connected to it. In this embodiment, the stirring shaft 9 is rotatably connected to the central shaft 7 via a bushing 14, improving stability. One end of the stirring shaft 9 extends into the housing 3 and is fixedly connected to multiple stirring rods 13, which are evenly distributed along the axial direction of the stirring shaft 9. The other end of the stirring shaft 9 is located outside the central shaft 7, and a second drive mechanism 10 for driving the stirring shaft 9 to rotate is provided on the base 1. The stirring rods 13 agitate the powder, allowing it to tumble and move during dehumidification, achieving dynamic dehumidification and further improving dehumidification efficiency and effect. The rotatable connection between the stirring shaft and the central shaft allows the housing and the stirring shaft to rotate independently without affecting each other, resulting in an optimized and stable structure.

[0032] Specifically, the second drive mechanism 10 includes a driven pulley 101 fixedly connected to the other end of the stirring shaft 9, and a second motor 102 fixedly connected to the base 1. A drive pulley 103 is fixedly connected to the output end of the second motor 102, and the drive pulley 103 and the driven pulley 101 are connected by a belt 104. The second motor 102 drives the drive pulley 103 to rotate, which in turn drives the driven pulley 101 to rotate via the belt 104, thereby rotating the stirring shaft 9 and causing the stirring rod 13 to stir the material.

[0033] Working principle: During feeding and dehumidification, the first motor 82 drives the rotating housing 3. When the first conical hopper 4 rotates to the top of the housing 1 and stops rotating, the slide valve 5 is opened, allowing powder to be added into the housing 3 through the second conical hopper 6. The powder is then dehumidified by the dehumidification component 11 below, and the generated moisture is directly discharged upwards through the second conical hopper 6. During dehumidification, the second motor 102 drives the stirring shaft 9 to rotate, causing the stirring rod 13 to stir the material, thus improving dehumidification efficiency.

[0034] After dehumidification is complete, discharge begins. The slide gate valve 5 is closed, and stirring is stopped. Then, the first drive mechanism 82 drives the housing 3 to rotate 180°, so that the first square cone hopper 4 rotates to the bottom of the housing 3. At this time, the slide gate valve 5 is opened, and the powder can be collected through the guide of the first square cone hopper 4 and discharged through the second square cone hopper 6. Compared with the existing technology, the discharge is smoother and less labor-intensive, and more convenient to use.
