Description
Technical Field
[0001] This utility model relates to the field of mixing devices, specifically a vertical mixing device. Background Technology
[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, capable of undergoing significant deformation under small external forces, and returning to its original shape after the force is removed. Rubber products are widely used in various aspects of industry and daily life, such as the manufacture of tires, hoses, seals, and gaskets.
[0003] In rubber processing, compounding is a crucial step. The purpose of compounding is to uniformly mix raw rubber or plasticized raw rubber with various compounding agents to produce a compound of uniform quality, thereby improving the physical and mechanical properties of rubber products and enhancing processing and molding techniques.
[0004] In existing rubber mixing processes, the raw materials are generally directly stirred and mixed. However, during use and observation, it has been found that when the raw materials contain a lot of moisture, the raw rubber is prone to mold growth during storage and also reduces the mixing quality of the materials by the equipment.
[0005] Therefore, a vertical mixing device is proposed to address the above problems. Utility Model Content

[0008] Preferably, a plurality of first baffles are fixedly connected inside the heat exchange tube; a plurality of second baffles are fixedly connected inside the heat exchange tube; both the first baffles and the second baffles are arc-shaped and staggered; through the cooperative action of the first baffles and the second baffles, the exhaust gas inside the heat exchange tube will have its flow path extended due to the obstruction of the first baffles and the second baffles, thereby increasing the heating time of the exhaust gas at the feed inlet and improving the utilization rate of the waste heat of the exhaust gas by the device.
[0009] Preferably, a second mesh plate is fixedly connected to one side of the first mesh plate; the end of the first mesh plate and the first exhaust pipe are rotatably connected; when the first mesh plate has been working for a long time, the surface of the first mesh plate may become clogged due to the accumulation of material. At this time, the second mesh plate can be rotated to make the component consisting of the second mesh plate and the first mesh plate rotate, so that the positions of the second mesh plate and the first mesh plate are interchanged, realizing the quick replacement of the first mesh plate by the device. Subsequently, the first mesh plate can be cleaned by a relevant cleaning device. It is worth mentioning that the rotating shaft between the component consisting of the second mesh plate and the first mesh plate and the first exhaust pipe can be a damping rotating shaft, so the second mesh plate and the first mesh plate can be in a stable state under normal conditions.
[0010] Preferably, connecting rods are symmetrically arranged through both sides of the tank and rotatably connected; a belt is sleeved between the connecting rods and the rotating shaft; a first bevel gear is fixedly connected to the end of the motor; a crossbar is symmetrically arranged through the middle of the tank and rotatably connected; a second bevel gear is fixedly connected to the end of the crossbar; the second bevel gear and the first bevel gear are meshed; multiple blades are fixedly connected to the other end of the crossbar; the blades are located inside the tank; when the motor starts, the connecting rods will rotate together with the rotating shaft under the transmission of the belt, and the first bevel gear will rotate with the connecting rod and mesh with the second bevel gear, so that the blades will rotate together with the crossbar. At this time, the material tumbling inside the tank will come into contact with the rotating blades and be cut and crushed by them, which facilitates the mixing of materials inside the tank.
[0011] Preferably, the air intake pipe is provided with a third mesh plate; the third mesh plate is used to filter the airflow; by setting the third mesh plate, when the air intake pipe is started, the third mesh plate will filter the airflow entering the air intake pipe, reducing the contamination effect of impurities carried in the airflow on the material in the tank.
[0012] Preferably, a spring is fixedly connected to the middle of the third mesh plate; a ball is fixedly connected to the end of the spring; the ball and the air inlet pipe are correspondingly arranged; when the air inlet pipe is connected to the hot air blower, the airflow will be ejected from the air inlet pipe.

At this time, the second mesh plate 3 can be rotated to make the assembly consisting of the second mesh plate 3 and the first mesh plate 111 rotate, so that the positions of the second mesh plate 3 and the first mesh plate 111 are interchanged, thereby realizing the quick replacement of the first mesh plate 111 by the device. Subsequently, the first mesh plate 111 can be cleaned by a relevant cleaning device. It is worth mentioning that the bearing between the assembly consisting of the second mesh plate 3 and the first mesh plate 111 and the first exhaust pipe 18 can be a damping bearing, so the second mesh plate 3 and the first mesh plate 111 can be in a stable state under normal conditions.
[0028] Please see Figure 2 and Figure 3 As shown, connecting rods 4 are symmetrically arranged and rotatably connected to both sides of the tank body 1; a belt is sleeved between the connecting rods 4 and the rotating shaft 15; a first bevel gear 42 is fixedly connected to the end of the motor 14; a crossbar 43 is symmetrically arranged and rotatably connected to the middle of the tank body 1; a second bevel gear 45 is fixedly connected to the end of the crossbar 43; the second bevel gear 45 and the first bevel gear 42 are meshed; multiple blades 44 are fixedly connected to the other end of the crossbar 43; the blades 44 are located inside the tank body 1; when the motor 14 starts, the connecting rods 4 will rotate together with the rotating shaft 15 under the transmission of the belt, and the first bevel gear 42 will rotate with the connecting rods 4 and mesh with the second bevel gear 45, so that the blades 44 rotate together with the crossbar 43. At this time, the material tumbling inside the tank body 1 will come into contact with the rotating blades 44 and be cut and crushed by them, which facilitates the mixing of the material inside the tank body 1.
[0029] Please see Figure 5As shown, the air intake pipe 17 is provided with a third mesh plate 5 inside; the third mesh plate 5 is used to filter the airflow; by setting the third mesh plate 5, when the air intake pipe 17 is started, the third mesh plate 5 will filter the airflow entering the air intake pipe 17, reducing the pollution effect of impurities carried in the airflow on the material in the tank 1.
[0030] Please see Figure 5 As shown, a spring 6 is fixedly connected to the middle of the third mesh plate 5; a ball 62 is fixedly connected to the end of the spring 6; the ball 62 and the air inlet pipe 17 are correspondingly arranged; when the air inlet pipe 17 is connected to the hot air blower, the airflow will be sprayed out from the air inlet pipe 17. Under normal conditions, the ball 62 will seal the air inlet pipe 17, further reducing the material entering the air inlet pipe 17. When the air pressure in the air inlet pipe 17 is too high, the ball 62 will be pushed out under the action of air pressure and the spring 6 will be in a stretched state until the air inlet pipe 17 stops ventilating. It is worth mentioning that the temperature of the hot air should not exceed the bearing limit of the spring 6, and the spring 6 can also be made of high temperature resistant material.
[0031] Working principle: Open the cover plate on the feed inlet 12 and pour the raw materials and additives into the tank 1 through the feed inlet 12. At the same time, start the motor 14 to make the rotating shaft 15 drive the spiral blades 16 to rotate. When the spiral blades 16 rotate, they will agitate the materials inside the tank 1, causing them to tumble and mix. At the same time, the valve at the air inlet pipe 17 can be opened and a hot air blower can be connected through the air inlet pipe 17 to allow hot air to enter the tank 1 through the air inlet pipe 17. The hot air will heat the reaction environment inside the tank 1 to reduce the moisture released during the mixing of the materials inside the tank 1. At the same time, the valve of the second exhaust pipe 110 can be opened and the second exhaust pipe 110 can be connected to an air pump to create a negative pressure inside the second exhaust pipe 110. In this state, the second exhaust pipe 110 will extract air from the inside of the tank 1 through the heat exchange pipe 19 and the first exhaust pipe 18 to remove high-temperature exhaust gas containing water vapor from the inside of the tank 1. The material contained in the exhaust gas will be blocked and filtered by the first mesh plate 111. When the high-temperature exhaust gas flows, it will pass through the heat exchange pipe 19. At this time, through heat exchange, the exhaust gas will preheat the material entering at the feed inlet 12, reducing the moisture carried in the material. The exhaust gas extracted by the second exhaust pipe 110 can be treated by relevant treatment devices, which will not be described in detail here. Finally, the mixed material can be discharged by opening the valve at the discharge port 13. When the exhaust gas flows inside the heat exchange pipe 19, because the first baffle 2 and the second baffle 22 are staggered. This causes the airflow to flow along the cavity between the first baffle 2 and the second baffle 22, and the airflow will flow in an S-shape inside the heat exchange tube 19, increasing the flow path of the airflow inside the heat exchange tube 19 and also increasing the heating time of the material flowing in the feed inlet 12 by the exhaust gas. When the first screen plate 111 has been working for a long time, the surface may become blocked due to the accumulation of material. At this time, the second screen plate 3 can be rotated to rotate the component consisting of the second screen plate 3 and the first screen plate 111, so that the positions of the second screen plate 3 and the first screen plate 111 are interchanged, realizing the quick replacement of the first screen plate 111. Subsequently, the first screen plate 111 can be cleaned by relevant cleaning devices. It is worth mentioning that the second screen plate 3 and the first screen plate 111 The bearing between the component 1 and the first exhaust pipe 18 can be a damping bearing, so the second screen plate 3 and the first screen plate 111 can be in a stable state under normal conditions. When the motor 14 starts, the connecting rod 4 will rotate with the rotating shaft 15 under the transmission of the belt, and the first bevel gear 42 will rotate with the connecting rod 4 and mesh with the second bevel gear 45, so that the blade 44 will rotate with the crossbar 43. At this time, the material tumbling inside the tank 1 will come into contact with the rotating blade 44 and be cut and crushed by it. By setting the third screen plate 5, when the air inlet pipe 17 starts, the third screen plate 5 will filter the airflow entering the air inlet pipe 17, reducing the pollution effect of impurities carried in the airflow on the material inside the tank 1.When the air inlet pipe 17 is connected to the hot air blower, airflow will be ejected from the air inlet pipe 17. Under normal conditions, the sphere 62 will seal the air inlet pipe 17, further reducing the amount of material entering the air inlet pipe 17. When the air pressure inside the air inlet pipe 17 is too high, the sphere 62 will be forced out under the pressure, causing the spring 6 to be in a stretched state until the air inlet pipe 17 stops ventilating. It is worth mentioning that the temperature of the hot air should not exceed the withstand limit of the spring 6, and the spring 6 can also be made of a high-temperature resistant material.
