Description

Technical Field

[0001] This utility model belongs to the field of plastic masterbatch technology, and specifically relates to a PVC plastic masterbatch drying device. Background Technology

[0002] PVC masterbatch is a special type of plastic additive, composed of a large number of chemical auxiliaries, carrier resins, and dispersants. Among various color masterbatches, black masterbatch stands out due to its prevalence and high demand. It is one of the most frequently used and consumed color masterbatches in the plastics processing industry.

[0003] Existing patent publication number CN209191057U discloses a plastic masterbatch stirring and drying device, including a drying device body, a feed inlet, a motor, a reducer, a discharge outlet, a bearing, and a fixing block. The feed inlet is located on the upper left side of the drying device body, and the motor is located in the middle of the upper part of the drying device body. The lower end of the motor is connected to a stirring rod via a reducer. The lower part of the stirring rod is connected to a dispersing plate via a bearing and a rotating port. A first stirring blade is located above the dispersing plate. An air inlet pipe is welded to the lower side wall of the drying device body, and a protective cover is bolted to the inner end of the air inlet pipe via a fixing block. A dispersing port is provided on the dispersing plate. This plastic masterbatch stirring and drying device, with a dispersing plate inside the drying device body and a second stirring blade on the stirring rod below the dispersing plate, mixes the falling plastic masterbatch with hot air, which is beneficial for the drying process of the plastic masterbatch.

[0004] However, in actual use, the equipment simply stirs and turns the masterbatch with a stirring rod, and then dries the masterbatch with hot air blown through the air inlet pipe. Since the masterbatch is in a piled-up state, the hot air does not heat the masterbatch evenly during drying, which affects the drying efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PVC plastic masterbatch drying device, which has the advantage of uniformly drying the masterbatch by turning it over.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PVC plastic masterbatch drying device, comprising a first connecting frame and a second connecting frame, a drying cylinder fixedly connected between the first connecting frame and the second connecting frame, a sieve cylinder fixedly connected inside the drying cylinder, a rotating rod rotatably connected inside the sieve cylinder, a rotary blade fixedly connected outside the rotating rod, a motor fixedly connected outside the drying cylinder, the output end of the motor fixedly connected to the rotating rod, a drying mechanism provided at the top of the first connecting frame, and a water outlet mechanism provided outside the drying cylinder.

[0007] Preferably, the drying mechanism includes two support frames, both of which are fixedly connected to the top of the first connecting frame, and a hot air fan is fixedly connected between the two support frames. The output end of the hot air fan is connected to a T-shaped connecting pipe.

[0008] Preferably, the outside of the drying cylinder is provided with a plurality of correspondingly distributed arc-shaped tubes, and the outside of each of the plurality of arc-shaped tubes is connected to a number of air outlets.

[0009] Preferably, several of the air outlets extend into the interior of the drying cylinder, and multiple air outlets are connected between the multiple arc-shaped tubes, with one of the arc-shaped tubes connected to a T-shaped connecting pipe.

[0010] Preferably, the water outlet mechanism includes two sealing plates, both of which are fixedly connected to the outside of the drying cylinder, and a water storage tank is fixedly connected between the two sealing plates. A valve is provided on the outside of the water storage tank.

[0011] Preferably, the drying cylinder is provided with a feeding port on the outside, and the feeding port is connected to the screen cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When drying the masterbatch raw material, first start the motor. The motor output drives the rotating rod to rotate, which in turn drives the rotary blades to rotate, thus turning the masterbatch raw material. At this time, start the hot air blower, and blow hot air into the T-shaped connecting pipe through the hot air blower output. Then, the hot air enters the air outlet pipe through the T-shaped connecting pipe, and then enters multiple arc-shaped pipes through the air outlet pipe. Finally, the hot air is blown out through multiple air outlets. The hot air surrounds the drying cylinder through multiple arc-shaped pipes and air outlets. This design significantly increases the surface area of ​​the masterbatch in contact with the hot air during the turning process. When the hot air blows on the turned masterbatch raw material, it can effectively dry its surface. Through the above mechanism, the masterbatch raw material can be turned and dried, so that it is heated more evenly during the drying process, and the drying efficiency of the masterbatch raw material can be effectively improved.

[0014] 2. When the masterbatch is being dried, excess water will adhere to its surface after pelleting because it is cooled with water before pelleting. When the masterbatch is turned over by the rotary blades, the water adhering to the surface of the masterbatch will fall off. Then the excess water will pass through the screen cylinder. Because there are grooves on the outside of the drying cylinder, the water will pass through the drying cylinder and then through the sealing plate into the water storage tank. The water is collected in the water storage tank, and the water inside the water storage tank can be discharged through the valve. Through the above mechanism, excess water that is not easy to evaporate during the drying of masterbatch raw materials can be collected, thereby further increasing the drying efficiency.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1-7 This utility model provides a technical solution: a PVC plastic masterbatch drying device, including a first connecting frame 1 and a second connecting frame 4, a drying cylinder 5 fixedly connected between the first connecting frame 1 and the second connecting frame 4, a sieve cylinder 7 fixedly connected inside the drying cylinder 5, a rotating rod 9 rotatably connected inside the sieve cylinder 7, a rotary blade 10 fixedly connected outside the rotating rod 9, a motor 8 fixedly connected outside the drying cylinder 5, the output end of the motor 8 fixedly connected to the rotating rod 9, a drying mechanism 2 provided on the top of the first connecting frame 1, and a water outlet mechanism 3 provided outside the drying cylinder 5.

[0026] In this embodiment, the drying cylinder 5 is supported by the first connecting frame 1 and the second connecting frame 4. Through the cooperation of the drying cylinder 5 and the screen cylinder 7, the masterbatch raw material is added into the screen cylinder 7 through the feeding port 6. The drying mechanism 2 can turn the masterbatch raw material over for drying, so that it is heated more evenly during drying and the drying efficiency of the masterbatch raw material can be effectively improved. The water outlet mechanism 3 can collect the excess water that is not easy to evaporate during the drying of the masterbatch raw material, thereby further increasing the drying efficiency.

[0027] Example 2:

[0028] Please see Figure 1-5 Based on Embodiment 1, this utility model provides a technical solution: the drying mechanism 2 includes two support frames 201, both of which are fixedly connected to the top of the first connecting frame 1. A hot air blower 202 is fixedly connected between the two support frames 201. The output end of the hot air blower 202 is connected to a T-shaped connecting pipe 203. A plurality of correspondingly distributed arc-shaped pipes 205 are provided on the outside of the drying cylinder 5. A plurality of air outlets 206 are connected to the outside of the plurality of arc-shaped pipes 205. The plurality of air outlets 206 extend into the interior of the drying cylinder 5. A plurality of air outlet pipes 204 are connected between the plurality of arc-shaped pipes 205. One of the arc-shaped pipes 205 is connected to the T-shaped connecting pipe 203. A feeding port 6 is provided on the outside of the drying cylinder 5, and the feeding port 6 is connected to the screen cylinder 7.

[0029] In this embodiment, when the masterbatch raw material needs to be dried, the motor 8 is first started. The output end of the motor 8 drives the rotating rod 9 to rotate. The rotation of the rotating rod 9 drives the rotary vane 10 to rotate. The rotation of the rotary vane 10 turns the masterbatch raw material. At this time, the hot air blower 202 is started. The output end of the hot air blower 202 blows hot air into the T-shaped connecting pipe 203. Then the hot air enters the air outlet pipe 204 through the T-shaped connecting pipe 203. Then the hot air enters the air outlet pipe 204 again through the air outlet pipe 204. The hot air is blown out through multiple arc-shaped tubes 205 and multiple air outlets 206. The multiple arc-shaped tubes 205 and air outlets 206 surround the outer periphery of the drying cylinder 5. This design significantly increases the surface area of ​​the masterbatch in contact with the hot air during the turning process. When the hot air blows on the turning masterbatch raw material, it can effectively dry its surface. Through the above mechanism, the masterbatch raw material can be turned and dried, so that it is heated more evenly during the drying process, and the drying efficiency of the masterbatch raw material can be effectively improved.

[0030] Example 3:

[0031] Please see Figure 1-7Based on Embodiment 1 and Embodiment 2, this utility model provides a technical solution: the water outlet mechanism 3 includes two sealing plates 301, both sealing plates 301 are fixedly connected to the outside of the drying cylinder 5, a water storage tank 303 is fixedly connected between the two sealing plates 301, and a valve 302 is provided on the outside of the water storage tank 303.

[0032] In this embodiment, when the masterbatch is being dried, since the masterbatch is cooled with water before pelleting, excess water will adhere to its surface after pelleting. When the masterbatch is turned over by the rotary blade 10, the water adhering to the surface of the masterbatch will fall off. Then the excess water will pass through the screen cylinder 7. Since the outside of the drying cylinder 5 has grooves, the water will pass through the drying cylinder 5 and then through the sealing plate 301 into the interior of the water storage tank 303. The water is collected by the water storage tank 303, and the water inside the water storage tank 303 can be discharged by the valve 302. Through the above mechanism, excess water that is not easy to evaporate during the drying of masterbatch raw materials can be collected, thereby further increasing the drying efficiency.

[0033] The working principle and usage process of this utility model are as follows: When it is necessary to dry the masterbatch raw material, the motor 8 is started first. The output end of the motor 8 drives the rotating rod 9 to rotate. The rotation of the rotating rod 9 drives the rotary blade 10 to rotate. The rotation of the rotary blade 10 turns the masterbatch raw material. At this time, the hot air blower 202 is started. The output end of the hot air blower 202 blows hot air into the T-shaped connecting pipe 203. Then the hot air enters the air outlet pipe 204 through the T-shaped connecting pipe 203. Then the hot air enters multiple arc-shaped pipes 205 through the air outlet pipe 204 again. The hot air is then blown out through multiple air outlets 206. The multiple arc-shaped pipes 205 and air outlets 206 surround the drying cylinder 5. This design significantly increases the surface area of ​​the masterbatch in contact with the hot air during the turning process. When the hot air blows on the turning masterbatch raw material, it can effectively dry its surface.

[0034] When the masterbatch is being dried, excess water will adhere to its surface after pelleting because the masterbatch is cooled by water before pelleting. When the masterbatch is turned over by the rotary blade 10, the water adhering to the surface of the masterbatch will fall off. Then the excess water will pass through the screen cylinder 7. Because the outside of the drying cylinder 5 has grooves, the water will pass through the drying cylinder 5 and then through the sealing plate 301 into the interior of the water storage tank 303. The water is collected by the water storage tank 303 and the water inside the water storage tank 303 can be discharged by the valve 302.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
