Sewage treatment device for aluminum profile production

Industrial wastewater includes production wastewater and production sewage, which refers to the wastewater and waste liquid produced in the industrial production process.

It contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water, with the rapid development of the industry.

The types and quantities of wastewater have increased rapidly, and the pollution of water bodies has become increasingly extensive and serious, threatening human health and safety.

Industrial wastewater generally contains particulate matter, which needs to be separated from the liquid during treatment.

For the recovery of industrial particles, the currently generally used method is the filtration method.

However, in the process of use, the filter screen is easy to be blocked, which affects the flow rate, and it is inconvenient to recover industrial particles, which affects the efficiency of sewage treatment.

The purpose of the utility model is to solve the problem that the filter screen in the prior art is easy to be blocked during use, which affects the flow rate.

It is inconvenient to recycle industrial particles and affects the efficiency of sewage treatment. Therefore, a sewage treatment device for aluminum profile production is proposed.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

A sewage treatment device for aluminum profile production includes a filter box.

A water inlet pipe is fixedly connected to the upper end of the filter box, a water outlet pipe is fixedly connected to the lower side wall of the filter box, and a water separator is fixedly connected to the lower end of the water inlet pipe.

A box door is clamped on the front side of the filter box, a fixing frame is clamped in the filter box, and a filter screen is fixedly arranged on the inner wall of the fixing frame close to the lower side.

A center plate is fixedly arranged at the center of the filter screen, a through hole is opened on the surface of the center plate, and a rotating rod is rotatably sleeved in the through hole through a ball bearing.

The upper end of the rotating rod is fixedly connected with a connecting block, the side wall of the connecting block is symmetrically and fixedly connected with a plurality of scrapers, and the surface of the filter screen is integrally provided with a plurality of collecting screen frames.

A rotating motor is fixedly connected to the lower end of the center plate, a positioning insert block is fixedly connected to the output shaft of the upper end of the rotating electrical machine, and a positioning slot corresponding to the positioning insert block is provided at the lower end of the rotating rod.

Preferably, the side wall of the box door is fixedly connected with an annular sealing block, and the side wall of the filter box is provided with an annular sealing groove which is matched and inserted with the annular sealing block.

Preferably, a plurality of U-shaped card plates are symmetrically and fixedly connected to the outer side wall of the filter box.

An L-shaped crimping plate crimped on the outside of the box door is rotatably connected to the inner wall on the opposite side of the U-shaped card plate through a pin shaft, and the L-shaped crimping plate and the box door are fixedly connected by fixing bolts.

Preferably, a plurality of wedge-shaped clamping blocks are symmetrically and fixedly connected to the inner side wall of the filter box.

The side wall of the fixing frame is provided with a plurality of dovetail card slots matched with the wedge-shaped card blocks.

The positioning insert block and the positioning slot are corresponding polygonal structures.

Preferably, the four corners of the bottom of the filter box are fixedly connected with support legs.

Compared with the prior art, the utility model provides a sewage treatment device for aluminum profile production, which has the following beneficial effects:

  1. The sewage treatment device for aluminum profile production, through the filter box provided, introduces sewage into the filter box through the water inlet pipe during sewage treatment, and the sewage can be evenly distributed on the filter net through the water separator.
  2. Effective filtration treatment can be carried out, and when a lot of impurities are accumulated on the filter net to affect the filtration efficiency, the rotating motor is started, and the rotating motor drives the connecting block to rotate, and then drives multiple scrapers to rotate.
  3. It can drive the impurities on the filter screen to move together, and when the impurities pass through the collecting screen frame, they will fall into the collecting screen frame, and then the impurities on the surface of the filter screen can be quickly and effectively collected.
  4. Avoid the problem of impurity clogging affecting the filtration efficiency, and ensure the continuous progress of sewage treatment.
  5. The sewage treatment device for aluminum profile production is provided with a box door, and the box door and the filter box can be detachably connected to facilitate the maintenance and operation of its internal mechanism.
  6. The cooperation of the annular sealing block and the annular sealing groove makes the connection between the filter box and the box door more sealed and fit, and then the L-shaped crimping plate is turned over by the rotational connection of the U-shaped clamping plate and the L-shaped crimping plate.
  7. The L-shaped crimping plate is crimped on the outer side of the box door to achieve fixation, and then the bolts can be used to realize the fixed connection, which can realize the quick disassembly and assembly of the box door, and is convenient for maintenance and use.

In addition, the parts not involved in the device are the same as the existing technology or can be realized by using the existing technology. The utility model can quickly and effectively collect the impurities on the surface of the filter screen, avoid the problem of impurity clogging affecting the filtration efficiency, and ensure the sewage Processing continues.
