Description

Technical Field

[0001] This utility model relates to the field of polyvinyl chloride processing technology, specifically to a polyvinyl chloride particle stirring device. Background Technology

[0002] Chlorinated polyvinyl chloride (CPVC) resin is produced by chlorination modification of polyvinyl chloride (PVC) resin. The product is a white or pale yellow, odorless, tasteless, and non-toxic loose granules or powder. Due to its excellent high-temperature resistance, corrosion resistance, and flame retardancy, and its relatively low price compared to other thermoplastic engineering plastics, CPVC resin is widely used in the manufacture of various pipes, sheets, profiles, plates, injection molded parts, foam materials, and anti-corrosion coatings. It is a promising new type of engineering plastic.

[0003] Polyvinyl chloride (PVC) resin raw materials are in granular form. During processing, they need to be heated and melted, and then stirred and mixed by a stirring device. Since PVC resin becomes a paste after being heated and melted, it is easy to deposit on the wall of the stirring tank and cause adhesion. Most existing stirring rods are located at the top of the stirring tank, which can easily lead to insufficient mixing of the material at the bottom of the stirring tank. Moreover, when resin particles fall to the bottom of the stirring tank, the temperature of the resin particles drops, the fluidity of the resin particles decreases, and they are prone to solidification, which affects the stirring efficiency. In view of this, a PVC particle stirring device is proposed. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-3 This utility model provides a new technical solution: a polyvinyl chloride particle stirring device, including a base 1, four uprights 2 fixedly installed on the upper surface of the base 1, four sliding rods 3 slidably sleeved on the inner surface of the four uprights 2, and a vibration platform 5 fixedly installed on the upper end of the four sliding rods 3.

[0027] The vibrating platform 5 is equipped with a discharge mechanism, which includes four first springs 4, a mixing tank 6, a sealing cover 7, a flexible heating jacket 8, a hollow column 9, a vibrating motor 10, an exhaust port 11, a second spring 12, a rubber sealing ring 13, a sliding block 14, a through hole 15, a motor 16, a stirring rod 17, and a discharge valve 18.

[0028] Furthermore, all four first springs 4 are fixedly installed on the lower surface of the vibration platform 5, and the lower ends of the four first springs 4 are respectively fixedly installed on the upper surface of the four uprights 2.

[0029] Four vibration motors 10 are fixedly installed on the lower surface of the vibration platform 5.

[0030] Furthermore, the mixing tank 6 is fixedly fitted onto the inner surface of the vibration platform 5, and the sealing cover 7 is fixedly installed on the upper surface of the mixing tank 6.

[0031] The discharge valve 18 is fixedly installed on the lower surface of the mixing tank 6.

[0032] Furthermore, the hollow column 9 is fixedly installed on the upper surface of the mixing tank 6, the second spring 12 is fixedly installed in the inner wall of the hollow column 9, the rubber sealing ring 13 is fixedly installed at the lower end of the second spring 12, and two vent holes 11 are opened on the outer surface of the hollow column 9.

[0033] Furthermore, the sliding block 14 is fixedly sleeved on the inner surface of the rubber sealing ring 13, and two through holes 15 are opened on the outer surface of the sliding block 14.

[0034] Furthermore, the motor 16 is fixedly installed on the lower surface of the mixing tank 6, and the stirring rod 17 is fixedly installed on the output end of the motor 16;

[0035] Among them, the flexible heating jacket 8 is fixedly sleeved on the outer surface of the mixing tank 6;

[0036] The flexible heating jacket 8 in this utility model is an electric heat tracing and insulation jacket, which is a flexible, detachable, and custom-made product that combines heat preservation and heating. The electric heat tracing and insulation jacket is set to keep the temperature of the material being insulated from exceeding the controllable range, and mainly plays the role of auxiliary heating and heat preservation.

[0037] When using this polyvinyl chloride (PVC) granule mixing device, PVC granules are added to the mixing tank 6 by opening the sealing cover 7. At this time, the motor 16 is started, which drives the stirring rod 17 fixedly installed at the output end to rotate. Simultaneously, the flexible heating jacket 8 is powered by an external power supply, which heats the bottom of the mixing tank 6 to prevent the temperature inside the tank from dropping. The tank is a sealed environment, and a large amount of hot air is stored inside the tank to prevent the temperature from dropping. Excess water vapor pushes the sliding block 14 to move upward. The sliding block 14 drives the rubber sealing ring 13 fixedly sleeved on the outer surface to move upward. The rubber sealing ring 13 applies pressure to the second spring 12 fixedly installed on the upper surface, causing it to contract. At this time, the sliding block 14 continues to move upward until the two through holes 15 on the outer surface of the sliding block 14 meet the hollow column. Two vent holes 11 on the outer surface of the 9 are aligned, which can discharge excess water vapor in the mixing tank 6 and ensure maximum utilization of residual heat in the tank. When discharging, the vibration motor 10 is started, which drives the vibration platform 5 to vibrate. The vibration motor 10 causes the vibration platform 5 to vibrate, which in turn causes the mixing tank 6 fixedly installed on the inner surface to vibrate. The vibration platform 5 applies pressure to the four first springs 4 fixedly installed on the lower surface. The elastic potential energy of the four first springs 4 can ensure the vibration amplitude of the vibration platform 5. The four sliding rods 3 fixedly installed on the inner surface of the vibration platform 5 slide on the outer surface of the four uprights 2 respectively. The sliding can maintain the direction of movement of the vibration platform 5. Through continuous vibration, the mixed polyvinyl chloride particles in the mixing tank 6 can be discharged.

[0038] This polyvinyl chloride (PVC) granule mixing device ensures a constant temperature at the bottom of the mixing tank 6 by fixing a flexible heating sleeve 8 around the outside of the mixing tank 6. The motor 16 and stirring rod 17 are both located at the bottom of the mixing tank 6, facilitating the mixing of PVC granules deposited thereon. A one-way valve structure is formed by the hollow column 9, vent 11, first spring 4, sliding block 14, and through hole 15, maximizing the utilization of heat generated inside the tank and ensuring the discharge of excess water vapor, preventing the temperature inside the tank from dropping and facilitating processing. After the PVC granules in the mixing tank 6 are fully mixed to meet usage requirements, the vibration motor 10 is activated. The vibration motor drives the vibration platform 5 to vibrate, which in turn drives the mixing tank 6 to vibrate. The first spring 4 enhances the vibration amplitude of the vibration platform 5, and the sliding rod 3 maintains the stability of the vertical vibration direction. Continuous vertical vibration prevents PVC granules from accumulating at the discharge valve, facilitating the discharge of cement slurry.

[0039] Working principle: When using this PVC granule stirring device, PVC granules are added to the stirring tank 6 by opening the sealing cover 7. At this time, the motor 16 is started, which drives the stirring rod 17 fixedly installed at the output end to rotate. Simultaneously, the flexible heating jacket 8 is powered by an external power supply, which heats the bottom of the stirring tank 6 to prevent the temperature inside the tank from dropping. The tank is a sealed environment, and a large amount of hot air is stored in the tank to prevent the temperature from dropping. The excess water vapor pushes the sliding block 14 to move upward. The sliding block 14 drives the rubber sealing ring 13 fixedly sleeved on the outer surface to move upward. The rubber sealing ring 13 applies pressure to the second spring 12 fixedly installed on the upper surface, causing it to contract. At this time, the sliding block 14 continues to move upward until the two through holes 15 on the outer surface of the sliding block 14 meet the air. The two vent holes 11 on the outer surface of the core column 9 are aligned, which can discharge excess water vapor in the mixing tank 6 and ensure maximum utilization of residual heat in the tank. When discharging, the vibration motor 10 is started, which drives the vibration platform 5 to vibrate. The vibration motor 10 causes the vibration platform 5 to vibrate, which in turn causes the mixing tank 6, which is fixedly installed on the inner surface, to vibrate. The vibration platform 5 applies pressure to the four first springs 4 fixedly installed on the lower surface. The elastic potential energy of the four first springs 4 can ensure the vibration amplitude of the vibration platform 5. The four sliding rods 3 fixedly installed on the inner surface of the vibration platform 5 slide on the outer surface of the four uprights 2 respectively. The sliding can maintain the direction of movement of the vibration platform 5. Through continuous vibration, the mixed polyvinyl chloride particles in the mixing tank 6 can be discharged.

[0040] 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.
