Description

Technical Field

[0001] The present invention relates to the field of drying equipment for removing liquid from solid materials or products, and in particular to a film resonance dehydration device and a drying system. Background Art

[0002] Chloroprene rubber (CR) is a general synthetic rubber obtained by polymerization of chloroprene monomer. In addition to the good physical properties of general rubber, it also has excellent properties such as weather resistance, oil resistance, and chemical resistance. At present, chloroprene rubber is mainly prepared by the butadiene method. The butadiene method mainly includes the following steps: Chloroprene monomer is prepared by emulsion polymerization to obtain latex. The polymerization is generally carried out under alkaline conditions (temperature 10~40℃). When a certain polymerization rate is reached, the polymerization reaction is stopped and the monomer is removed. Then the pH value of the latex is adjusted, and then it is sent to a coagulation tank with a freezing drum. Cooling brine below -15℃ is passed into the cooling drum, and the latex is frozen into a film on the surface of the drum. After washing and dehydration, the frozen film is sent to the drying equipment for thorough drying, and then cut into ropes and packed for shipment.

[0003] The main purpose of frozen film washing is to remove salt, acid and other water-soluble impurities carried by the condensate (or tape). If the washing is not thorough, it will affect the physical properties of the product; dehydration refers to squeezing and dehydrating the condensate with a water content of about 50%, so that the water content of the condensate is reduced to below 10% and then sent to the drying equipment for circulating hot air drying until the water content is further reduced to below 1.0%.

The film is fed from the right side, and the film is squeezed and dehydrated through the squeezing area formed between the upper pressing roller 2.4 and the lower supporting roller 3.7; the film is vibrated and dehydrated when passing through the vibrating pressing plate 2.10. The liquid and particles separated from the film fall into the inner collecting tank 3, and are introduced into the liquid storage tank through the collecting tank 3.1 and the guide tank 3.2.

[0062] During the dehydration process, film particles may adhere to the pores of the first mesh belt 1.5, affecting water separation; for this reason, in a preferred embodiment of the present invention, a mesh belt cleaning device 5 is further provided inside the first mesh belt 1.5.

The mesh belt cleaning device 5 of the present invention includes a cleaning substrate 5.1, and the cleaning substrate 5.1 is parallel to the first mesh belt 1.5 passing between the two first rotating shafts 1.2 on the left side, and the cleaning substrate 5.1 is connected to the side of the inner collecting tank 3 through a connecting rod. A water spray pipe 5.2 is arranged horizontally on the cleaning substrate 5.1, and a nozzle 5.5 is arranged on the water spray pipe 5.2. The same side of the water spray pipe 5.2 is connected to the second water inlet pipe 5.3, and the water inlet end of the second water inlet pipe 5.3 is connected to a water pump through a water pipe, and the water pump provides high-pressure water after pumping water and pressurizing. Furthermore, a fiber cluster 5.4 is also provided on the cleaning substrate 5.1 and between adjacent water spray pipes 5.2, and the fiber cluster 5.4 can extend into the pores of the first mesh belt 1.5 for cleaning.

[0064] like Fig.13 As shown, specifically, the end face of the cleaning substrate 5.1 is provided with countersunk holes 5.6 arranged in a matrix, and a positioning seat 5.7 is connected to the inner thread of the countersunk hole 5.6. The cross-sectional shape of the positioning seat 5.7 is T-shaped, and a T-shaped hole 5.8 is provided in the center of the positioning seat 5.7. The large diameter end of the T-shaped hole 5.8 faces the countersunk hole 5.6. The T-shaped hole 5.8 is used to plug in a fiber cluster 5.4. The cross-sectional shape of the fiber cluster 5.4 is T-shaped. A first spring 5.9 is installed in the countersunk hole 5.6. The first spring 5.9 is elastically connected between the countersunk hole 5.6 and the fiber cluster 5.4. By setting a detachable fiber cluster 5.4, replacement is facilitated, and the first spring 5.9 makes the fiber cluster 5.4 always protrude outward. When the fiber cluster 5.4 encounters resistance, it can adaptively shrink, thereby improving the effect of cleaning the film particles.
