Problems solved by technology

[0027] But, there are some problems in the described program of using filter press type karst water deposit dewatering machine to carry out karst water deposit dehydration treatment
For example, when the karst water deposit dehydration rubberized roll of the filter press type karst water deposit dewatering machine undergoes multiple karst water deposit dehydration procedures, the pores on the karst water deposit dehydration rubberized roll will be covered with karst water deposit particles Severe blockage will even cause the water in the karst water deposits to fail to filter out, making the filter press dehydrator unable to work

Abstract

The invention provides a maintaining device for a coating roller of carbon tetrachloride karst water deposit and an operating method for the maintaining device. An automatic cleaning device comprises a supporting base, a cleaning agent stock solution tank, a rotating center shaft, a rotating platform, a lifting telescopic column, a supporting vertical column, a rotating connecting rod, an angle adjusting pushing rod, a cleaning liquid spraying device and a cleaning liquid adding device, wherein the cleaning agent stock solution tank and the rotating center shaft are arranged on the upper part of the supporting base; the rotating platform which is rotatably connected to the upper end of the rotating center shaft is driven by a rotating control motor; the lifting telescopic column is fixedly connected to the peripheral between the rotating platform and the supporting platform; the supporting vertical column is fixedly connected to the upper part of the supporting platform; one end of the rotating connecting rod is hinged to the upper end of the supporting vertical column; two ends of the angle adjusting pushing rod are correspondingly hinged to the supporting vertical column and the rotating rod; the cleaning liquid spraying device is hinged to the other end of the rotating connecting rod; and the cleaning liquid adding device is connected with a liquid inlet of the cleaning liquid spraying device and a liquid outlet of the cleaning agent stock solution tank. The operating method for the maintaining device comprises the step that an automatic cleaning liquid spraying head is automatically controlled through a central controller to spray cleaning liquid to the dirt part. The maintaining device for the coating roller of carbon tetrachloride karst water deposit is reasonable is structure and high in integration, and the operating method for the maintaining device is helpful to improve working efficiency of the coating roller.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a carbon tetrachloride karst water deposit rubberized roll maintenance device and an operating method thereof, which belong to the technical field of building structures. Background technique [0002] Carbon tetrachloride (CCl 4 ) is a synthetic low-boiling organic chlorinated hydrocarbon (specific gravity 1.591g / cm 3 , boiling point 77°C), slightly soluble in water. Foreign studies have shown that carbon tetrachloride is a typical liver poison, and at high concentrations, it first affects the central nervous system, and then affects the liver and kidneys. It has persistence, long-term residue and bioaccumulation in the environment. Therefore, it has been listed by the US EPA as "Priority Control Pollutants in Groundwater Containing Carbon Tetrachloride" since 1979, and it has also been included in my country's 68 " Priority pollutants in water" list. [0003]...
