Description

Technical Field

[0001] This utility model belongs to the field of rubber processing dehydration technology, specifically a rubber processing dehydration device. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can undergo large deformation under small external forces. After the external force is removed, it can return to its original shape. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight. Rubber products are widely used in various aspects of industry and daily life.

[0003] The specific design and structure of cable tray protection devices may vary depending on different manufacturers and application requirements, but generally they include the following key components: barrel, discharge device, and transmission device. The barrel is generally made of high-quality wear-resistant steel and is the component that holds the rubber material and the screw. The discharge device is located at the end of the dewatering device and is used to discharge the dewatered rubber material. The transmission device is used to drive the screw to rotate, providing power for the conveying and dewatering of the rubber material.

[0004] Existing rubber dehydration equipment uses a single dehydration method. For rubbers with a dense structure and difficult-to-extract moisture, this method is slow. For rubbers with high moisture content, centrifugation at the beginning is inefficient and fails to remove large amounts of moisture quickly, resulting in a long overall dehydration process that cannot meet production efficiency requirements. Moreover, existing dehydration equipment may still leave a small amount of residual moisture in the rubber material after dehydration. During subsequent storage, this residual moisture may cause the rubber to mold and deteriorate. In subsequent processing, the moisture may affect the processing performance of the rubber. Since there is no effective mechanism to treat this residual moisture, the quality of rubber products is difficult to guarantee. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a dehydration device for rubber processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a dehydration device for rubber processing, including a dehydration tank, a squeezing cylinder at the top of the dehydration tank, a squeezing plate at the output end of the squeezing cylinder, the squeezing plate being disposed inside the dehydration tank, a transmission rod rotatably disposed at the bottom of the dehydration tank, a dehydration barrel at the top of the transmission rod, and a drain hole on the dehydration barrel; a drying hood is disposed on the side of the dehydration barrel, a heating tube is disposed inside the drying hood, a fan bracket is disposed on the side of the dehydration tank, a drying fan is disposed on the fan bracket, an air inlet pipe and a drying pipe are disposed on the drying fan, and the other end of the drying pipe is disposed on the drying hood.

[0007] Preferably, a driven gear is provided at the bottom end of the transmission rod, a motor bracket is provided at the bottom end of the dehydration tank, a transmission motor is provided on the motor bracket, a transmission gear is provided at the output end of the transmission motor, and the transmission gear meshes with the driven gear. The transmission motor drives the transmission rod to rotate through the meshing of the transmission gear and the driven gear. This transmission method has an accurate transmission ratio and can ensure that the dehydration tank rotates at a stable speed, thereby ensuring the uniformity and stability of the dehydration and drying process.

[0008] Preferably, the dehydration tank is provided with a feeding port, and a guide plate is provided on the feeding port. The top of the guide plate is located above the dehydration tank. The design of the feeding port and the guide plate makes it easy to put the rubber to be processed into the dehydration tank. The guide plate can guide the rubber to fall accurately into the dehydration tank, avoiding the rubber from scattering during the feeding process, thus improving the convenience and accuracy of feeding.

[0009] Preferably, the dehydration tank is hinged with a second sealing door, which is equipped with a second handle. The dehydration box is hinged with a first sealing door, which is equipped with a first handle. The first and second sealing doors effectively prevent moisture and heat leakage during dehydration and drying, ensuring the working environment inside the device, improving the dehydration and drying effect, and avoiding impact on the surrounding environment. The handle design facilitates the opening and closing of the doors.

[0010] Preferably, a drain pipe is provided at the bottom of the dehydration tank, and a drain valve is provided on the drain pipe. The drain pipe and drain valve at the bottom of the dehydration tank are used to discharge the wastewater generated during the dehydration process. The drain valve can control the timing and speed of drainage to ensure that the wastewater can be discharged in a timely and smooth manner and to avoid the accumulation of wastewater in the dehydration tank.

[0011] Preferably, the extrusion cylinder, heating tube, drying fan, and drive motor are connected to an external controller. The controller is used to start and stop the extrusion cylinder, heating tube, drying fan, and drive motor, realizing automated operation, improving production efficiency, and also facilitating parameter adjustment according to different rubber processing requirements, making the device more adaptable and flexible.

[0012] The advantages of this invention are: it combines extrusion dehydration with rotary centrifugal dehydration. The extrusion cylinder drives the extrusion plate to apply pressure to the rubber in the dehydration barrel, quickly squeezing out a large amount of water; the drive motor drives the dehydration barrel to rotate, using centrifugal force to further separate the water in the rubber. This diversified dehydration method improves the dehydration efficiency and effect, and can remove the water from the rubber more thoroughly than a single dehydration method.

[0013] A drying hood is installed on the side of the dehydration drum, with heating tubes installed inside. A drying fan sends hot air into the drying hood to dry the rubber. Drying is carried out simultaneously during the dehydration process, which not only removes residual moisture but also accelerates moisture evaporation, reduces dehydration time, and avoids quality problems in storage or subsequent processing of the rubber due to residual moisture.

[0030] Working principle: In order to dehydrate the rubber material, the rubber material to be dehydrated is guided into the dehydration tank 3 through the feeding port 13 and the guide plate 14. Then, the extrusion cylinder 15 is started, and the output end of the extrusion cylinder 15 pushes the extrusion plate 16 downward to apply extrusion pressure to the rubber material in the dehydration tank 3.
