Description

A preheating device for processing rubber composite materials Technical Field

[0001] This utility model relates to the field of rubber material processing technology, specifically to a preheating device for processing rubber composite materials. Background Technology

[0002] In the rubber production process, rubber needs to be vulcanized. The vulcanization temperature of rubber is 165-175 degrees Celsius. If production is started directly, it is difficult to form the product. Therefore, the preheating temperature must be reached before production can begin. This requires a rubber processing preheating device.

[0003] However, in actual use, traditional heating devices usually place the rubber raw material in a fixed position for heating treatment. The raw material is then transported for further processing after it is heated. This can easily cause the temperature of the raw material to drop during transportation. Moreover, if the temperature of the rubber raw material is raised too high at one time, it can easily cause sticking and other problems, affecting transportation. In addition, the traditional transportation method uses fixed pipelines, which makes it inconvenient to adjust the transportation position and angle during use. Summary of the Invention

[0004] The purpose of this invention is to provide a preheating device for processing rubber composite materials, which solves the problems of inconvenience in adjusting the transportation position and angle during the processing and transportation of existing rubber materials, and the tendency for the temperature to drop during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a preheating device for processing rubber composite materials, including a mixing tank, an installation cylinder is provided on one side of the bottom of the mixing tank, a conveying pipe is installed on the outer wall of the installation cylinder, a discharge cylinder is installed at the end of the conveying pipe away from the installation cylinder, a heating rod is provided through the center of the discharge cylinder, and a hollow heat-insulating sleeve is fitted on the outer wall of the conveying pipe.

[0006] The bottom of the mounting cylinder is rotatably connected to a connecting cylinder, and the side walls of both the mounting cylinder and the connecting cylinder are fixedly connected to the conveying pipe.

[0007] A rotating tube is installed through the center of the conveying pipe, and a spiral blade is fixedly connected to the outer wall of the rotating tube. The heating rod is connected through the interior of the rotating tube.

[0008] A stirring rod is installed at the center of the mixing tank, and multiple heat-conducting pipes are arranged around the side wall of the mixing tank. A rotating cylinder is rotatably connected to the bottom of the mixing tank.

[0009] Preferably, a motor is installed at the top of the stirring rod, the bottom of the mixing tank is inclined towards the center and is funnel-shaped, and the position of the heat pipe is staggered from the position of the stirring blade outside the stirring rod.

[0010] Preferably, the conveying pipe on the outer wall of the mounting cylinder is connected to the rotating cylinder, the rotating pipe penetrates the interior of the rotating cylinder, and the bottom of the rotating cylinder is closed.

[0011] Preferably, a discharge cylinder is provided on one side of the connecting cylinder, and one side of the discharge cylinder is connected to the interior of the connecting cylinder through a conveying pipe. A rotating pipe passes through the interior of the discharge cylinder, the top of the discharge cylinder is closed, and an electric heating wire is installed on the outer wall of the discharge cylinder.

[0012] Preferably, the outer wall of the conveying pipe is fitted with a hollow insulation sleeve, and the top and bottom of both ends of the hollow insulation sleeve are respectively provided with connecting pipes. The connecting pipes at the top of the two hollow insulation sleeves near the mounting cylinder are connected by a conduit. The connecting pipe at the end of the hollow insulation sleeve near the mixing tank is connected to the heat-conducting pipe through a conduit. The connecting pipe at the end of the hollow insulation sleeve near the discharge cylinder is connected to the liquid supply pump.

[0013] Preferably, a drive motor is installed on the outer wall of both the mounting cylinder and the connecting cylinder, and one end of the rotating tube is fixedly connected to the power output end of the drive motor.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. Start the drive motor, which in turn drives the rotating tube inside the mounting cylinder and connecting cylinder to rotate, thereby causing the spiral blades to rotate. This allows the rubber raw material to be carried along the conveying pipe to the mounting cylinder, and then moves the rubber raw material to the bottom of the discharge cylinder, thus realizing the transportation of materials. Since the rotating cylinder and the mixing tank are rotatably connected, the rotation of the rotating cylinder can be easily adjusted, thereby driving the conveying pipe to move. Furthermore, since the mounting cylinder and the connecting cylinder are rotatably connected, they can also be easily rotated relative to each other, thereby driving the position of the discharge cylinder to move and adjust through the conveying pipe, facilitating the transportation of materials to different locations.

[0016] 2. The rubber raw material inside the mixing tank is initially heated by the heat-conducting pipe. Simultaneously, the motor drives the rubber raw material to move back and forth via the stirring rod, ensuring uniform contact between the rubber raw material and the heat-conducting pipe, thus achieving uniform heating of the rubber raw material. During material transportation, the outer wall of the conveying pipe is equipped with a hollow insulation sleeve, allowing high-temperature liquid to be transported to the hollow insulation sleeve through the connecting pipe, thereby transferring heat to the conveying pipe and raising the temperature of the rubber raw material. When the material is conveyed to the discharge cylinder, the heating rod is activated, raising the temperature of the rotating pipe and spiral blades, further heating the rubber material and facilitating subsequent vulcanization treatment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides a preheating device for processing rubber composite materials, as shown in Figures 1-5. It includes a mixing tank 1, an mounting cylinder 2 at one bottom side of the mixing tank 1, a conveying pipe 3 mounted on the outer wall of the mounting cylinder 2, a discharge cylinder 4 mounted at the end of the conveying pipe 3 away from the mounting cylinder 2, a heating rod 5 penetrating through the center of the discharge cylinder 4, and a hollow insulation sleeve 6 fitted onto the outer wall of the conveying pipe 3. A connecting cylinder 201 is rotatably connected to the bottom of the mounting cylinder 2, and the side walls of both the mounting cylinder 2 and the connecting cylinder 201 are fixedly connected to the conveying pipe 3. A rotating pipe 301 is penetrating through the center of the conveying pipe 3, and a spiral blade 302 is fixedly connected to the outer wall of the rotating pipe 301. The heating rod 5 is penetratingly connected to the interior of the rotating pipe 301. A stirring rod 101 is mounted at the center of the mixing tank 1, multiple heat-conducting pipes 102 are arranged around the side wall of the mixing tank 1, and a rotating cylinder 103 is rotatably connected to the bottom end of the mixing tank 1.

[0027] The drive motor 303 drives the rotating tube 301 inside the mounting cylinder 2 and the connecting cylinder 201 to rotate, thereby causing the spiral blades 302 to rotate. This allows the rubber raw material to be carried along the conveying pipe 3 to the mounting cylinder 2. Simultaneously, the drive motor 303 on the outer wall of the connecting cylinder 201 drives the rotating tube 301 inside the conveying pipe 3 to rotate, further conveying the rubber raw material to the discharge cylinder 4. The rotation of the rotating cylinder 103 can be easily adjusted to move the conveying pipe 3. Furthermore, since the mounting cylinder 2 and the connecting cylinder 201 are rotatably connected, it also facilitates... The installation cylinder 2 and the connecting cylinder 201 rotate relative to each other, which in turn drives the position of the discharge cylinder 4 to move and adjust through the conveying pipe 3, making it convenient to transport materials to different positions. The high-temperature liquid is transported to the hollow insulation sleeve 6 through the connecting pipe 601, so that heat can be transferred to the conveying pipe 3, thereby raising the temperature of the rubber raw material. When the material is transported to the position of the discharge cylinder 4, the heating rod 5 can be activated to heat it, thereby raising the temperature of the rotating pipe 301 and the spiral blade 302, further heating the rubber material and raising the temperature, which is convenient for subsequent vulcanization treatment.

[0028] As shown in Figures 1 and 3, a motor is installed at the top of the stirring rod 101. The bottom of the mixing tank 1 is inclined towards the center and is funnel-shaped. The position of the heat-conducting pipe 102 is staggered from the position of the stirring blade outside the stirring rod 101. The conveying pipe 3 on the outer wall of the mounting cylinder 2 is connected to the rotating cylinder 103. The rotating pipe 301 penetrates the interior of the rotating cylinder 103. The bottom of the rotating cylinder 103 is closed. The rubber raw material inside the mixing tank 1 can be initially heated by the heating of the heat-conducting pipe 102. At the same time, the motor drives the rubber raw material to move back and forth through the stirring rod 101, so that the rubber raw material can be evenly contacted with the heat-conducting pipe 102, thereby achieving uniform heating of the rubber raw material.

[0029] As shown in Figures 4 and 5, a discharge cylinder 4 is provided on one side of the connecting cylinder 201. One side of the discharge cylinder 4 is connected to the interior of the connecting cylinder 201 through the conveying pipe 3. The rotating pipe 301 penetrates the interior of the discharge cylinder 4. The top of the discharge cylinder 4 is closed. An electric heating wire is installed on the outer wall of the discharge cylinder 4. A drive motor 303 is installed on the outer wall of both the mounting cylinder 2 and the connecting cylinder 201. One end of the rotating pipe 301 is fixedly connected to the power output end of the drive motor 303. When the drive motor 303 is started, it drives the rotating pipe 301 inside the mounting cylinder 2 and the connecting cylinder 201 to rotate, thereby causing the spiral blade 302 to rotate. This allows the rubber raw material to be carried along the conveying pipe 3 to the mounting cylinder 2. At the same time, the drive motor 303 on the outer wall of the connecting cylinder 201 drives the rotating pipe 301 inside the conveying pipe 3 to rotate, thereby further conveying the rubber raw material to the discharge cylinder 4, and then causing the rubber raw material to move towards the bottom of the discharge cylinder 4.

[0030] As shown in Figures 1 and 4, a hollow insulation sleeve 6 is fitted onto the outer wall of the conveying pipe 3. Connecting pipes 601 are respectively installed at the top and bottom of both ends of the hollow insulation sleeve 6. The connecting pipes 601 at the top of the two hollow insulation sleeves 6 near the mounting cylinder 2 are connected by a conduit. The connecting pipe 601 at the end of the hollow insulation sleeve 6 near the mixing tank 1 is connected to the heat-conducting pipe 102 via a conduit. The connecting pipe 601 at the end of the hollow insulation sleeve 6 near the discharge cylinder 4 is connected to the liquid supply pump, allowing the high-temperature liquid to be transported to the hollow insulation sleeve 6 through the connecting pipes 601. The heat insulation sleeve 6 allows heat to be transferred to the conveying pipe 3, thereby increasing the temperature of the rubber raw material. The connecting pipe of the hollow heat insulation sleeve 6 near the discharge cylinder 4 is connected to the liquid supply pump, so that the temperature inside the conveying pipe 3 near the discharge cylinder is higher, and the temperature of the hollow heat insulation sleeve 6 near the mixing tank 1 is lower. This allows the temperature inside the conveying pipe 3 to increase sequentially towards the discharge cylinder 4, which facilitates the sequential increase of the rubber raw material temperature, prevents the rubber raw material temperature from decreasing, and improves the heat utilization efficiency.

[0031] In use, the rubber raw materials to be processed can be conveniently poured into the mixing tank 1, and then the stirring rod 101 can be started to rotate, so that the rubber raw materials can be mixed together. In addition, the drive motor 303 can be started, which drives the rotating tube 301 inside the mounting cylinder 2 and the connecting cylinder 201 to rotate, thereby causing the spiral blades 302 to rotate. This allows the rubber raw materials to be carried along the conveying pipe 3 to the mounting cylinder 2. At the same time, the drive motor 303 on the outer wall of the connecting cylinder 201 drives the rotating tube inside the conveying pipe 3. Rotation of cylinder 301 further conveys the rubber raw material into the discharge cylinder 4, causing it to move towards the bottom of the discharge cylinder 4, thus achieving material transportation. Since the rotating cylinder 103 is rotatably connected to the mixing tank 1, the rotation of the rotating cylinder 103 can be easily adjusted, thereby driving the conveying pipe 3 to move. Furthermore, since the mounting cylinder 2 and the connecting cylinder 201 are rotatably connected, the mounting cylinder 2 and the connecting cylinder 201 can also be easily rotated, thereby driving the position of the discharge cylinder 4 to move and adjust through the conveying pipe 3, facilitating the delivery of materials to different locations.

[0032] The rubber raw material inside the mixing tank 1 is initially heated by the heat-conducting pipe 102. Simultaneously, the motor drives the rubber raw material to move back and forth via the stirring rod 101, ensuring uniform contact between the rubber raw material and the heat-conducting pipe 102, thus achieving uniform heating. During material transportation, the outer wall of the conveying pipe 3 is equipped with a hollow insulation sleeve 6, allowing high-temperature liquid to be transported to the hollow insulation sleeve 6 through the connecting pipe 601, thereby transferring heat to the conveying pipe 3 and raising the temperature of the rubber raw material. When the material reaches the discharge cylinder 4, the heating rod 5 is activated for further heating. This causes the temperature of the rotating tube 301 and the spiral blade 302 to rise, further heating the rubber material and facilitating subsequent vulcanization. Furthermore, the liquid inside the hollow insulation jacket 6 can transfer heat to the mixing tank 1. Since the connecting pipe of the hollow insulation jacket 6 near the discharge cylinder 4 is connected to the liquid supply pump, the temperature inside the conveying pipe 3 near the discharge cylinder is higher, while the temperature of the hollow insulation jacket 6 near the mixing tank 1 is lower. This allows the temperature of the conveying pipe 3 to rise sequentially towards the discharge cylinder 4, facilitating a sequential increase in the temperature of the rubber raw material, preventing a decrease in the rubber raw material temperature, and improving heat utilization efficiency.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
