Description

Technical Field

[0001] The utility model relates to a wastewater treatment device. Background Art

[0002] Glassine paper has the functions of high temperature resistance, moisture resistance, oil resistance, etc. It is generally used in food, medical and other industries. It is mainly used for high-speed automatic labeling special tapes, double-sided tape substrate trademarks, and laser anti-counterfeiting labels. Nowadays, paper has been widely used in people's daily production and life, and a large amount of wastewater will be generated in the process of paper manufacturing. Usually, the wastewater is directly discharged. The wastewater contains pulp, which will cause a large amount of waste of paper raw materials and water resources. If the pulp cannot be recycled in time, a large amount of production raw materials will be wasted. If the wastewater cannot be effectively purified, it will affect water quality safety and cannot meet social environmental protection needs. Utility Model Content

[0004] The above technical problems of the utility model are mainly solved by the following technical solutions:

[0005] A wastewater treatment device comprises a box body, and support feet arranged at the bottom of the box body, and a box cover arranged at the top of the box body, and a first motor arranged at the outer bottom of the box body, and a filter drum arranged at the inner bottom of the box body and connected to the first motor, and a drain outlet arranged at the bottom of the side wall of the box body, and a water inlet arranged at the upper end of the side wall of the box body, and two guide plates arranged in the middle of the inner wall of the box body, and a filter screen arranged in the box body above the guide plate, and a second motor arranged on the outer wall of the box body, and a driven wheel arranged in the side wall of the box body, and a transmission chain arranged in the side wall of the box body, one end of which is connected to the second motor and the other end is connected to the driven wheel.

[0006] Preferably, one end of the filter screen is connected to a transmission chain, and the filter screen is raised and lowered following the rotation of the transmission chain. The inner wall of the box body is provided with bar holes for the filter screen to move up and down.

[0007] Preferably, the first motor drives the filter drum to rotate, and the filter drum is detachable and can be taken out from the top of the box.

[0008] Preferably, the filter screen can be removed after rising to the opening position at the top of the box body.

[0009] Preferably, the guide plate is vertically arranged on the inner wall of the box body, the top of the guide plate is inclined, and the gap between the two guide plates corresponds to the filter drum.

[0010] The beneficial effects of the wastewater treatment device of the utility model are as follows: since the wastewater treatment device adopts a filter screen for the first filtration, the filter screen can be driven by the second motor to rise and fall after filtration, so as to collect the pulp on the filter screen; the setting of the two guide plates can well allow the wastewater filtered once to enter the filter drum for secondary filtration, and the filter drum rotates at a constant speed under the drive of the first motor, so that the fine pulp in the wastewater is retained in the filter drum, and after the filtration is completed, the filter screen can be taken out and the filter drum can also be taken out to collect the pulp; the setting of the box cover can prevent the wastewater from splashing out during the filtration.
