Description

Dust removal device for automatic open mill

Technical Field

The application relates to the technical field of rubber equipment, and in particular relates to a dust removal device for an automatic open mill, which has the advantages of simple structure, good dustproof effect and no influence on daily maintenance.

Background

The mixing is a process of uniformly dispersing and mixing compounding agents such as a softening agent, stearic acid, carbon black and the like into rubber compound in raw rubber or plastication by a rubber mixing mill through mechanical action, and is the most important production process for rubber processing. Rubber mixing mills are mainly classified into open type and closed type according to their structures, and open mills are short for open type rubber mixing mills. The open mill produces shearing force through two rollers which move relatively at different rotating speeds to mix rubber materials, and due to the open structure, various mixed powder is easy to fly everywhere, so that the air quality of a production workshop is seriously affected, hidden dangers of dust explosion exist, and the health of operators is also harmed. At present, for the problem of dust pollution in the mixing process, a suction pipe or an exhaust fan is generally used for taking flying dust away from the open mill. The exhaust fan can only disperse high-concentration dust in the open mill into peripheral air quickly, and although the problem of high local dust concentration of the open mill can be solved, the dust pollution range of a workshop can be expanded, so that the exhaust fan can only be used temporarily; in order to improve the dust removal effect, a dust suction cover communicated with a suction pipe is generally arranged at the top of the open mill, and then dust is conveyed to a dust filtering device at the rear end through the suction pipe to be filtered, so that the dust pollution problem of a workshop can be basically solved. Because manual mill upper portion needs reinforced and ejection of compact operation from the side, and automatic mill's last unloader gets into from the side more, though the operation of mill is not influenced to top suction hood, still cause just also to have great operation neutral gear between mill and the suction hood for the dust spills over from the neutral gear easily and continues the polluted air, and spill over in order to reduce the dust and can cause the power that needs increase negative-pressure air fan or pump, make the energy consumption of dust removal higher.

In order to solve the problem that the mill removed dust and exists among the prior art, have through setting up the structure of large-scale dust cover with whole mill aircraft bonnet in it, though simple structure and dustproof effect are better, but its area is too big, and routine maintenance needs loaded down with trivial details dismantlement installation, goes up unloading moreover and can only adopt belt or pipe-line transportation for the compounding time that goes up unloading occupy is too much, has reduced compounding efficiency. Therefore, a dust blocking curtain and a sliding window are arranged between the top dust hood and the open mill, so that dust overflow can be reduced, feeding and discharging operations can be facilitated through the dust blocking curtain and the sliding window, and the dust overflow is difficult to avoid due to the existence of gaps among the dust blocking curtains; although the rigid structure of the sliding window can reduce dust overflow, the daily maintenance also needs complicated disassembly and assembly, and the dust blocking curtain and the sliding window need to be pushed open when the two structures are used for loading and unloading, so that the operation process is increased, the loading and unloading efficiency can be influenced, and the labor intensity can be improved.
