A belt filter press used for printing and dyeing wastewater treatment

Abstract

The invention relates to the technical field of printing and dyeing wastewater treatment related equipment, and discloses a belt filter press used for printing and dyeing wastewater treatment. The belt filter press includes a supporting plate. Connection pipes are fixedly mounted to left and right sides of the lower surface of the supporting plates. A vertical column is fixedly mounted on the right side of the upper surface of the supporting plate, and an inclined bar is fixedly connected to the left side of the supporting plate. The middle of the left side of the vertical column is fixedly connected to a connection plate. The left end of the connection plate is fixedly connected to the top end of the inclined bar. According to the belt filter press, through cooperation among a cross bar,limiting slots, a telescopic bar, a pull cap, a blocking bar and a shrinkable spring, a user can pull the pull cap to block the blocking bar in the limiting slots having different heights so that thedistance between upper and lower rotary rollers is changed indirectly, thus increasing pressure between the rotary cylinders and a filter belt, facilitating cleaning of impurities on the external surface of the filter belt by a user, and increasing the sludge conveying speed of the filter belt of the belt filter press.

Description

technical field [0001] The invention relates to the technical field of equipment related to printing and dyeing sewage treatment, in particular to a belt filter press for printing and dyeing sewage treatment. Background technique [0002] The dehydration process of the belt filter press can be divided into four important stages: pretreatment, gravity dehydration, wedge-shaped zone pre-press dehydration and press dehydration. The technology uses a new type of equipment filter program-controlled automatic box filter press, diaphragm filter press, deep sewage Mud dewatering filter press, integrated sewage sludge treatment equipment, online precision filtration system and other environmental protection filtration products with reasonable price and reliable performance. The mud cake in the common belt filter press will clump together during the reciprocating motion of the material sorting mechanism It becomes a large lump of mud. The mud sticks to the rake and cannot pass through...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the comparative example, the present invention provides a belt filter press for printing and dyeing sewage treatment, which has the advantages of improving the speed of sludge transmission by the filter belt of the filter press, facilitating cleaning of the inside of the filter press and reducing the pressure of the filter press. The mechanical loss and other advantages solve the problem that the belt filter press does not clean the filter belt on the filter press, and then it is easy to reduce the speed of the sludge conveyed by the filter belt, and the sludge in the trapezoidal box of the belt filter press is easy to settle. The bottom of the box is not convenient for users to clean, and the belt filter press is not equipped with a shock absorber. When the machine is running, the friction between the bodies increases, which is easy to cause mechanical loss to the machine.
