Sewage filtering device for industrial production

Abstract

The invention relates to the technical field of sewage filtering attachments and particularly relates to a sewage filtering device for industrial production. According to the sewage filtering device,a water temperature of sewage can be adjusted to improve a flocculating effect of a flocculant, and part of heat is recovered from the sewage, so that the practicability is improved; the consumption of the flocculant can be controlled, the impurity removal is thorough, and the reliability of use is improved. The sewage filtering device comprises a box body and a motor, wherein a working chamber isarranged inside the box body, a filter screen is arranged in the working chamber, the motor is mounted at the bottom end of the box body, a rotating shaft is arranged at the top output end of the motor, and stirring vanes are arranged on the rotating shaft. The sewage filtering device further comprises a temperature regulating box, a communicating pipe, a first water pump, a second water pump, aheat conducting coil pipe, a conveying pipe, a temperature sensor, a temperature display, a water gage and an electromagnetic valve. The sewage filtering device further comprises a chemical solution tank, a gear metering pump, a controller and a water drain pipe.

[0002] As we all know, the sewage filter device used in industrial production is an auxiliary device that filters the sewage produced in industrial production and prevents pollution to the water environment. It has been widely used in the fields of metallurgy and chemical industry; the existing The sewage filtering device used in industrial production includes a box body and a motor. The inside of the box body is provided with a working chamber, and a filter screen is arranged in the working chamber. The top of the box body is provided with a water inlet pipe and a feeding pipe. There is a drain pipe, the motor is installed at the bottom of the box, and a rotating shaft is installed at the output end of the top of the motor. The leaf is located in the working chamber; when the existing sewage filter device for industrial production is used, the sewage is introduced into the working chamber from the water inlet pipe, and then an appropriate amount of flocculant is introduced into the working chamber from the feeding pipe, and the flocculant is used to make the The suspended particles in the sewage condense into flocs. After the flocs grow to a certain extent, they will settle under the action of gravity. The motor drives the stirring blade to rotate, so that the sewage and the flocculant are fully mixed, and the sediment in the sewage is filtered through the filter. , the supernatant is exported through the drainage pipe; in the use of the existing sewage filtration devices used in industrial production, it is found that most of the industrial sewage is cooling water, the water temperature is high, and the flocculation effect is poor if the flocculation and precipitation are carried out directly through the flocculant. The produced flocs are small and difficult to handle, which affects the effect of sewage filtration and impurity removal; and the amount of flocculant cannot be controlled. When the amount of flocculant is insufficient, the flocculation will not be complete. If the amount of flocculant is too large, the colloid will be re-stabilized and the flocculation will be reduced. effect, resulting in lower reliability in use
