Sewage, usually refers to the effluent from living and production that is polluted to a certain extent.
Sewage mainly includes domestic sewage, industrial waste water and initial rainwater. The main pollutants of sewage are pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. Plastic pipes are made of plastic resin, stabilized, lubricated agent, etc.
There are mainly PVC pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, ultra-high molecular weight polyethylene pipes, etc.
The existing sewage treatment devices have the following shortcomings:
- It is inconvenient to clean the large particles of impurities accumulated on the filter plate. After a long time of filtration, the filter plate is easily blocked, reducing the efficiency of filtration.
- It is inconvenient to take out the filter plate for replacement and maintenance, which reduces the work efficiency.
(1) Technical problems solved
VERTSLOT provides a sewage treatment device for plastic processing, which solves the problems that the existing sewage treatment device is inconvenient to clean the large-particle impurities accumulated on the wedge wire filter screen and inconvenient to take out the filter plate for replacement and maintenance.
(2) Technical solutions
In order to achieve the above purpose, the utility model provides the following technical solutions: a sewage treatment device for plastic processing, comprising a cylinder, a cover plate is inserted on the top of the cylinder, and a motor is provided on the top of the cover plate.
The output shaft of the motor penetrates and extends to the bottom of the cover plate, the output shaft of the motor is fixedly connected with a rotating shaft, and the surface of the rotating shaft is fixedly sleeved with a sleeve.The surface of the sleeve is fixedly connected with four vertical plates distributed in an annular array, and the bottom of the vertical plates is fixedly connected with brushes.
The bottom of the rotating shaft is rotatably connected with a filter disc, and a T-shaped rod is inserted into the bottom of the filter disc.
The top of the T-bar is inserted with four Vee Wire Scallop distributed in a circular array.
The bottom of the cylinder is fixedly connected with a filter box, and the bottom of the filter box is connected with a water conduit.
One side of the filter box is provided with a rectangular hole, and the inner wall of the rectangular hole is slidably connected with a rectangular box.
The inner wall of the rectangular box is fixedly connected with a first L-shaped plate.
The surface sliding sleeve of the first L-shaped plate is provided with a first filter layer.
The bottom of the first filter layer is provided with a second filter layer, and the bottom of the second filter layer is provided with an activated carbon layer.
The top of the T-shaped rod is provided with a chute, one side of the fan-shaped cylinder is fixedly connected with a plug board, and the plug board is slidably connected with the inner wall of the chute.
As a preferred technical solution of the present invention, the top of the T-shaped rod is provided with a circular groove, the bottom diameter of the circular groove is smaller than the top diameter, the inner wall of the circular groove is provided with a groove, and the bottom of the circular groove is fixedly connected with a first spring.
One side of the filter box is fixedly connected with a block, and a square slot is opened on the top of the block.
One side of the rectangular box is fixedly connected with an L-shaped rod.
The surface of the L-shaped rod is slidably connected with a second L-shaped plate.
The top of the second L-shaped plate is provided with a second spring which is movably sleeved on the surface of the L-shaped rod.
A feed pipe is communicated with the top of the cover plate, and a water inlet is opened on one side of the cylinder.
(3) Beneficial effects
Compared with the prior art, the utility model provides a sewage treatment device for plastic processing, which has the following beneficial effects:
- The sewage treatment device for plastic processing is matched by a motor, a rotating shaft, a vertical plate, a filter disc and a vee wire scallop, wherein the motor can drive the rotating shaft to rotate at a constant speed.
When the rotating shaft rotates, it can drive the vertical plate to rotate at a uniform speed, and the vertical plate can stir the sewage in the cylinder when it rotates, so as to increase the mixing effect of sewage and medicine.
At the same time, the vertical plate can drive the brush at the bottom to rotate, and the brush is in contact with the top of the filter disc, which can sweep the large particles of impurities accumulated on the top of the filter disc into the fan-shaped cylinder.
The vee wire scallop can collect large particles of impurities, because the surface of the fan-shaped cylinder is set as a wedge wire screen, so the impurities are retained in the fan-shaped cylinder. The water after preliminary filtration can continue to flow downward through the fan-shaped cylinder, so that the impurities accumulated on the surface of the filter disc can be cleaned without stopping the machine, so as to avoid clogging the filter disc and improve the filtering effect.
- The sewage treatment device for plastic processing is matched with a rectangular box, a first filter layer, a second filter layer, an activated carbon layer, a second L-shaped plate and a second spring.
The activated carbon layer can absorb the odor in sewage.
The second spring can play the role of reset, and the arrangement of the second L-shaped plate is convenient to fix the position between the rectangular box and the filter box.
Therefore, the whole rectangular box can be quickly pulled out from the inside of the filter box, which facilitates the replacement and maintenance of the first filter layer, the second filter layer and the activated carbon layer, and improves labor efficiency.
