Description

Dissolved rubber filtering device

Technical Field

The utility model relates to the field of chemical equipment, in particular to a dissolved rubber filtering device which is high in filtering efficiency and convenient to operate.

Background

In the preparation process of protective clothing, need coat the surface of base cloth with different mucilage layers to reach ideal protective effect, and need dissolve granular rubber into the mucilage through continuous stirring earlier before the coating, for example: fluororubbers, nitrile rubbers, butyl rubbers, chlorosulfonated polyethylene rubbers, and the like.

In the prior art, stirring is usually performed in a stirring tank mode, namely, granular rubber is poured into a tank body firstly, and then the rubber in the tank body is continuously stirred by a stirring device until the rubber is dissolved into mucilage. These cements often have residual rubber particles present and therefore it is necessary to filter the cement beforehand to remove the residual rubber particles before the coating operation is carried out.

The prior art mostly utilizes mucilage self gravity and combines the mode of screen cloth to directly filter, and this kind of filtration mode is simple structure, and the cost is lower, but same its filtration efficiency is also extremely low.

For this purpose, the inventor designs a filtering device as shown in fig. 1, which comprises an air-operated diaphragm pump 1a and a filtering tank 2a, wherein one end of the air-operated diaphragm pump 1a is connected to a stirring tank (not shown in the figure) through a pipeline; the other end of the pneumatic diaphragm pump 1a is connected with a filter tank 2a through a pipeline, and a cylindrical screen 3a similar to the filter tank 2a in shape is arranged in the filter tank 2 a. In use, the rubber cement is fed into the filter tank 2a by the air-operated diaphragm pump 1a, the fed cement flows from the inside of the cylindrical screen 3a to the outside of the cylindrical screen 3a to complete the filtration, the qualified slurry after the filtration is discharged from the lower outlet, and the rubber particles are retained in the cylindrical screen 3 a. Although the structure can obviously improve the filtering efficiency, the structure also has the problem of troublesome cleaning, namely, after the filtering is finished each time, workers need to open the filtering tank, take out the cylindrical screen and pour out the rubber particles in the cylindrical screen.

In a recommended embodiment, the filtering part comprises a hollow cylindrical framework and a screen, and the screen is sleeved outside the cylindrical framework.

In a recommended embodiment, the filter tank comprises a first filter tank and a second filter tank which are matched with each other, a feed inlet of the first filter tank is communicated with the pneumatic diaphragm pump, a feed inlet of the second filter tank is communicated with a discharge outlet of the first filter tank, and the mesh number of the screen of the second filter tank is larger than that of the screen of the first filter tank. After two times of filtration, the ideal filtering effect is ensured to be obtained.

In a preferred embodiment, the mesh number of the first filtration tank is 40-60 mesh; the mesh number of the screen of the second filtering tank is 100-120 meshes.

As can be seen from the above description of the present invention, the advantages of the present invention are:

during filtering, the mucilage enters the inner side from the outer side of the cylindrical filtering part, and rubber particles are always blocked at the outer side of the cylindrical filtering part and are precipitated at the lower part of the tank body. When cleaning, the rubber particles can be discharged only by opening the sewage draining port, and the cylindrical filtering part is not required to be taken out, so that the problem of troublesome cleaning is effectively solved.
