A metal precipitation collection device for sewage treatment

Abstract

The invention discloses a metal precipitation collection device for sewage treatment, which can solve the problem that the traditional sewage treatment process needs to use chemical reagents. On the one hand, the cost is high; The internal components of the device, the existing metal precipitation collection device also does not use chemical reagents but uses rolling rollers to crush the precipitated particles and then collect them. Rolling can only be deformed and will not be crushed. Although this method is low in cost, it is easy to cause the metal particles that are squeezed and deformed to stick to the outer wall of the rolling roller during rolling, resulting in incomplete collection of sediment. . It includes a cleaning frame, a bottom frame and a bottom support. The cleaning frame is fixed on the top of the bottom frame through a bracket. The bottom support is located on one side of the bottom frame. There are conveyor belts.

Description

technical field [0001] The invention relates to the field of metal precipitation collection devices, in particular to a metal precipitation collection device for sewage treatment. Background technique [0002] In the traditional sewage treatment process, it is necessary to use a metal precipitation collection device to collect the metals in the sewage, and use chemical reagents to replace the metals precipitated in the sewage, so as to realize the recovery of metal particles. This method requires the use of As far as chemical reagents are concerned, on the one hand, the cost is high, and on the other hand, chemical reagents are corrosive to a certain extent, and are easy to corrode the internal components of the precipitation collection device. The existing metal precipitation collection devices do not use chemical reagents but use rolling rollers to correct the precipitation. The particles are rolled and then collected for precipitation. The rolling rollers use the characte...

Problems solved by technology

[0004] The purpose of the present invention is to provide a metal precipitation collection device for sewage treatment, which can solve the problem of using a metal precipitation collection device to collect metals in sewage in the traditional sewage treatment process, and use chemical reagents to treat the precipitation in sewage. Replacement treatment of the metal, so as to achieve the recovery of metal particles, this method requires the use of chemical reagents, on the one hand, the cost is high, on the other hand, the chemical reagents are corrosive to a certain extent, and are easy to corrode the internal components of the precipitation collection device. Some metal precipitation collection devices do not use chemical reagents but use rolling rollers to crush the precipitated particles and then collect them. During the rolling process, the rolling rollers will only deform when the metal particles are crushed. It will not be crushed. Although this method is low in cost, it is easy to cause the metal particles that are squeezed and deformed to stick to the outer wall of the rolling roller during rolling, resulting in incomplete collection of sediment.
