Description

Technical Field

[0001] This utility model belongs to the field of drying technology, and in particular relates to a drying equipment for the production of polytetrafluoroethylene vinyl composite materials. Background Technology

[0002] Polytetrafluoroethylene (PTFE-based) composites combine the excellent chemical resistance, high temperature resistance and low friction properties of PTFE with the reinforcing properties of other fillers (such as glass fiber, graphite, etc.). They are widely used in sealing, heat insulation, lubrication and other fields, and have good mechanical properties and stability.

[0003] In the production of polytetrafluoroethylene (PTFE) based composites, the uniformity of drying is crucial, especially when the particles are placed on a flat surface for drying. Since the part of the particle bottom in contact with the surface is difficult to be heated or have moisture removed evenly, local overheating or incomplete drying may occur. To address this, we provide a drying equipment for the production of polytetrafluoroethylene composites. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the production of polytetrafluoroethylene vinyl composite materials. The device uses a rotating shaft to drive the polytetrafluoroethylene vinyl composite material inside the drying cylinder to rotate, so that it is heated evenly. This solves the problem that the bottom of the particles in contact with the plane is difficult to be heated evenly or to remove moisture.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a drying equipment for the production of polytetrafluoroethylene vinyl composite materials, including a drying mechanism, a screening mechanism at the bottom of the drying mechanism, a dryer inside the drying mechanism, a motor on the left side of the drying mechanism, and a rotating shaft fixedly connected to the bottom output shaft of the motor through a coupling.

[0007] The drying mechanism includes a support frame, the top of which is fixedly connected to the bottom of a motor. A heat insulation cylinder is fixedly connected to the inner wall of the support frame. A rotating groove is opened inside the heat insulation cylinder. A drying cylinder is rotatably connected to the inner wall of the rotating groove. A heat inlet hole is opened inside the drying cylinder. A rotating shaft is rotatably connected to the inner wall of the heat insulation cylinder. A connecting shaft is fixedly connected to the bottom of the rotating shaft. A pulley is fixedly connected to the outer surface of the rotating shaft. A belt is driven to the outer surface of the pulley. A second pulley is driven to the inner end of the belt away from the pulley. A valve is fixedly connected to the bottom of the heat insulation cylinder.

[0008] Furthermore, the outer surface of the rotating shaft is rotatably connected to the inner wall of the support frame, the outer wall of the connecting shaft is fixedly connected to the drying cylinder, the inner wall of the second pulley is fixedly connected to the outer surface of the rotating shaft, and the inner wall of the heat insulation cylinder is fixedly connected to the dryer.

[0009] Furthermore, the screening mechanism includes a screening box, and a sliding groove is provided inside the screening box.

[0010] Furthermore, a screening plate is slidably connected to the inner wall of the sliding groove, and a fixing block is fixedly connected to the outer wall of the screening box.

[0011] Furthermore, a second rotating shaft is rotatably connected to the inner wall of the first fixed block, and two second rotating shafts are designed in total. An eccentric block is fixedly connected to the outer surface of the second rotating shaft.

[0012] Furthermore, a worm gear is fixedly connected to the outer surface of the rotating shaft, and a worm is fixedly connected to the bottom of the rotating shaft.

[0013] Furthermore, the worm gear meshes with the worm wheel, a second fixing block is fixedly connected to the outer wall of the screening box, and a telescopic spring is fixedly connected to the inner wall of the second fixing block.

[0014] Furthermore, a total of three telescopic springs are provided, the outer wall of the telescopic springs is fixedly connected to the inner wall of the screening plate, and a collection box is fixedly connected to the bottom of the screening box.

[0015] This utility model has the following beneficial effects:

[0016] This invention, by setting up a drying cylinder, allows the dryer to preheat the air inside the insulated cylinder before drying the material. The material is then poured into the drying cylinder through the feed pipe. At this point, the motor is started, driving the rotating shaft to rotate. Simultaneously, pulley two drives the surface belt to rotate, which in turn drives the bottom connecting shaft to rotate. This causes the drying cylinder to rotate within the rotating groove, causing the material inside to rotate. This ensures that the surface is fully in contact with the hot air, guaranteeing that heat is evenly distributed throughout the material, effectively accelerating moisture evaporation, improving drying efficiency, and ensuring optimal drying results, avoiding over-drying or uneven drying.

[0017] This invention utilizes eccentric blocks. After the material inside the drying drum is dried, the valve can be opened, allowing the material to fall into the sieve box and onto the surface of the screening plate. Simultaneously, the rotating shaft drives the worm gear at the bottom to rotate, causing the eccentric blocks on both sides to rotate in a circular motion. The eccentric blocks then rhythmically press against the screening plate, causing it to slide within the sliding groove. At the same time, the screening plate compresses multiple telescopic springs on one side, causing it to contract. When the eccentric blocks are not pressing against the screening plate, the multiple telescopic springs cause the screening plate to spring back to its original position. This process repeats, causing the screening plate to continuously move left and right, shaking and screening the material on the surface. This not only helps separate particles that adhered during drying but also separates particles of different sizes based on their size and shape, ensuring a more uniform final particle size.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a drying equipment for the production of polytetrafluoroethylene vinyl composite material, including a drying mechanism 1, a screening mechanism 2 at the bottom of the drying mechanism 1, a dryer 5 inside the drying mechanism 1, a motor 3 on the left side of the drying mechanism 1, and a rotating shaft 4 fixedly connected to the bottom output shaft of the motor 3 through a coupling.

[0029] The drying mechanism 1 includes a support frame 111, the top of which is fixedly connected to the bottom of a motor 3. The motor 3 drives a rotating shaft 4 to rotate, which in turn drives a rotating shaft 106 to rotate. This rotating shaft 106 then drives a connecting shaft 105 to rotate, which in turn drives the drying cylinder 102 to rotate, thereby rotating the internal granular material. This ensures that the material is heated evenly during the drying process. As the drying cylinder rotates, the friction and tumbling between the particles help improve heat transfer efficiency, ensuring that each particle is dried quickly and evenly at a suitable temperature, thus improving the overall drying effect and production efficiency. A heat insulation cylinder 101 is fixedly connected to the inner wall of the support frame 111. The heat insulation cylinder 101 effectively prevents the dissipation of heat generated by the dryer 5, thereby improving drying efficiency. A rotating groove 109 is provided inside the heat insulation cylinder 101, and a drying cylinder is rotatably connected to the inner wall of the rotating groove 109. The drying cylinder 102 has a heat inlet hole 110 inside, which can effectively distribute the hot air emitted by the dryer 5 into the interior of the drying cylinder 102. A rotating shaft 106 is rotatably connected to the inner wall of the heat insulation cylinder 101. A connecting shaft 105 is fixedly connected to the bottom of the rotating shaft 106. A pulley 104 is fixedly connected to the outer surface of the rotating shaft 106. A belt 107 is drivenly connected to the outer surface of the pulley 104. The inner wall of the belt 107 is away from the inner wall of the dryer 102. One end of pulley 104 is connected to pulley 108. The inner wall of the heat insulation cylinder 101 is fixedly connected to the dryer 5. A valve 103 is fixedly connected to the bottom of the heat insulation cylinder 101. The outer surface of the rotating shaft 4 is rotatably connected to the inner wall of the support frame 111. The outer wall of the connecting shaft 105 is fixedly connected to the drying cylinder 102. The inner wall of pulley 108 is fixedly connected to the outer surface of the rotating shaft 4. The screening mechanism 2 includes a screening box 201. A sliding groove 207 is opened inside the screening box 201.

[0030] A screening plate 205 is slidably connected to the inner wall of the sliding groove 207. The motor 3 rotates the rotating shaft 4, which in turn drives the worm 202 at the bottom to rotate, which in turn drives the worm wheel 210 to rotate. Subsequently, the rotating shaft 203 drives the eccentric block 204 to rotate in a circular motion. The eccentric block 204 regularly squeezes the screening plate 205, causing it to slide slightly within the screening box 201, thereby screening the dried material particles, removing particles that do not meet the specifications, ensuring uniform particle size, and providing more stable material for subsequent processing. A fixing block 206 is fixedly connected to the outer wall of the screening box 201. The rotating shaft 203 is rotatably connected to the inner wall of the fixing block 206. There are two rotating shafts 203. The eccentric block 204 is fixedly connected to the outer surface of the rotating shaft 203, and the worm wheel 210 is fixedly connected to the outer surface of the rotating shaft 203. The worm 202 is fixedly connected to the bottom of the rotating shaft 4.

[0031] The worm gear 202 meshes with the worm wheel 210. A fixing block 208 is fixedly connected to the outer wall of the screening box 201, and a telescopic spring 211 is fixedly connected to the inner wall of the fixing block 208. The telescopic spring 211 can retract when the eccentric block 204 pushes the screening plate 205, and when the eccentric block 204 does not push the screening plate 205, the telescopic spring 211 will drive the screening plate 205 to reset. This process is repeated, so that the screening plate 205 slides continuously inside the screening box 201. There are three telescopic springs 211 in total. The outer wall of the telescopic spring 211 is fixedly connected to the inner wall of the screening plate 205. A collection box 209 is fixedly connected to the bottom of the screening box 201. The collection box 209 can collect the screened material, thereby effectively reducing manpower consumption.

[0032] One specific application of this embodiment is:

[0033] Before drying the material, the dryer 5 can be started to preheat the air inside the heat insulation cylinder 101. Then, the material is poured into the drying cylinder 102 through the feed pipe. At this time, the motor 3 can be started, and the motor 3 will drive the rotating shaft 4 to rotate. The rotating shaft 4 will then drive the second pulley 108 on the surface to rotate. At the same time, the second pulley 108 will drive the belt 107 on the surface to rotate. The belt 107 will then drive the first rotating shaft 106 to rotate. At this time, the first rotating shaft 106 will drive the connecting shaft 105 at the bottom to rotate, thereby allowing the drying cylinder 102 to rotate in the rotating groove 109. The drying cylinder 102 will then drive the material inside to rotate, so that the surface can fully contact the hot air, thereby ensuring that the heat can be evenly distributed to all parts of the material, effectively accelerating the evaporation of moisture, improving the drying efficiency, ensuring that the drying effect of the material reaches the best state, and avoiding over-drying or uneven drying.

[0034] After the material inside the drying cylinder 102 is dried, valve 103 can be opened, and the material will fall into the sieve box 201 and onto the surface of the screening plate 205. Simultaneously, the rotating shaft 4 rotates, driving the worm gear 202 at the bottom to rotate. The worm gear 202 then drives the worm wheel 210 to rotate, which in turn drives the internal rotating shaft 203 to rotate. This rotating shaft 203 then drives the eccentric blocks 204 on both sides to rotate in a circular motion. The eccentric blocks 204 then rhythmically press against the screening plate 205, causing it to slide within the sliding groove 207. Meanwhile, the screening plate 205 will compress multiple telescopic springs 211 on one side to retract. When the eccentric block 204 is not compressing the screening plate 205, the multiple telescopic springs 211 will drive the screening plate 205 to spring back and reset. This process is repeated, and the screening plate 205 will move left and right continuously to shake and screen the material on the surface. This not only helps to separate the sticky particles, but also separates particles of different sizes according to their size and shape, ensuring that the final screened particles are more uniform. After drying and screening, the material will fall into the collection box 209 for collection.
