Description

Technical Field

[0001] The present application relates to the field of coal chemical technology, and in particular to a novel vacuum belt filter press control cabinet. Background Art

[0002] The vacuum belt filter is a new type of filtration equipment with a high degree of automation. It uses filter cloth or filter screen as the medium, arranges the slurry horizontally on the filter medium, and makes full use of the slurry gravity and vacuum suction to achieve solid-liquid separation. The vacuum belt filter can be applied to materials under various concentration conditions, with high filtration efficiency, and is therefore preferred by many industries.

[0003] In the coal-to-methanol wastewater system, the vacuum belt filter is a key core equipment. During normal operation, due to the different process requirements for filter cake thickness and dryness and humidity or when a fault occurs and the machine needs to be shut down for maintenance, it is necessary to repeatedly switch on and off the electrical control cabinet for frequency modulation or power outage. At this time, a large amount of high-concentration acid and moisture in the environment will enter the control cabinet, which can easily cause corrosion of electrical components in the cabinet, reduced insulation of the control circuit, soft failures, etc., which are difficult to troubleshoot and cause frequent abnormal shutdowns of the vacuum belt filter press. This not only prolongs the maintenance time of the vacuum belt filter press, but also affects the safe and stable operation of the sewage system. In addition, the cabinet doors of most vacuum belt filter press control cabinets are prone to loosening after long-term use, which makes it easier for external gases to enter the cabinet and cause corrosion.

[0004] In view of the above problems, the inventor proposed a novel vacuum belt filter press control cabinet. Summary of the invention
