Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of styrene-butadiene rubber production, and in particular to a drying device for styrene-butadiene rubber production. Background Technology
[0002] In the production of styrene-butadiene rubber (SBR), the drying process is crucial, directly affecting the final quality of the rubber and production efficiency. Traditional drying equipment often suffers from low drying efficiency; at the same time, harmful gases generated during the drying process are difficult to effectively treat and can easily leak directly into the environment, posing a threat to the health of production personnel and the ecological environment.
[0003] Therefore, we designed a multi-roller sliding contact power supply device to meet the needs of practical applications. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a drying device for the production of styrene-butadiene rubber.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Design a drying device for styrene-butadiene rubber production, including a drying chamber, a circulation mechanism and a shaking mechanism inside the drying chamber, the circulation mechanism including a fan hood fixedly installed inside the drying chamber, a hot air fan fixedly installed at the top of the drying chamber, the outlet pipe of the hot air fan connected to the fan hood, a box body fixedly installed on the side of the drying chamber, the inlet pipe of the hot air fan connected to the box body, and a conduit fixedly installed at the bottom of the box body, one end of the conduit connected to the drying chamber;
[0007] The shaking mechanism includes a slide rod, which is slidably disposed inside the drying chamber. A plug-in frame is fixedly installed at one end of the slide rod, and a frame body is inserted into the inner wall of the plug-in frame. The inner wall of the frame body is provided with wire mesh.
[0008] In detail, the box is set vertically and is cylindrical in shape.
[0009] In detail, the inner wall of the box is provided with a first filter screen, a second filter screen and a third filter screen, and the first filter screen is made of non-woven fabric.
[0010] In detail, the second filter screen is made of activated carbon, and the third filter screen is made of HEPA filter.
[0011] In detail, the sliding rod is a square rod and is set horizontally.
[0012] In detail, a mounting plate is fixedly installed on the side of the drying oven, a motor is fixedly installed on the mounting plate, and a turntable is fixedly installed on the shaft end of the motor.
[0013] In detail, the turntable is disc-shaped, a limit rod is fixedly installed at the top of the turntable, and a strip frame is fixedly installed at one end of the slide rod, and the limit rod slides within the strip frame.
[0014] Core function: When styrene-butadiene rubber (SBR) needs to be dried, open the drying chamber, place the SBR inside the frame, then close the drying chamber and start the hot air blower and motor. When the hot air blower is working, it will draw the gas inside the drying chamber through the chamber and duct, heat it, and then blow it onto the SBR through the fan hood. During this process, the gas inside the drying chamber will continuously flow through the chamber. The chamber is equipped with a first filter, a second filter, and a third filter to filter the gas and prevent harmful gases from leaking out.
[0015] When the motor is working, the limit rod will be driven to make a circular motion through the turntable. When the limit rod makes a circular motion, it will drive the slide rod to make a linear reciprocating motion along the through hole between the slide rod and the drying box through the frame. When the slide rod makes a linear reciprocating motion, it will drive the frame to make a linear reciprocating motion through the plug frame, thereby achieving the purpose of shaking the styrene-butadiene rubber, which is beneficial to the drying of the styrene-butadiene rubber.
[0016] The design scheme proposed in this utility model has the following beneficial effects in application:
[0017] 1. The circulation mechanism facilitates the circulation of gas within the drying chamber, accelerating the gas flow rate and thus facilitating the drying of styrene-butadiene rubber. Simultaneously, the gas flow process allows for adsorption and filtration, preventing the leakage of harmful substances.
[0018] 2. By setting up a shaking mechanism, the styrene-butadiene rubber is shaken, which helps to accelerate the drying efficiency of the styrene-butadiene rubber. Attached Figure Description
