Description

Technical Field

[0001] The utility model relates to a sewage treatment device, in particular to a sewage treatment device for environmental protection engineering. Background Art

[0002] In order to protect the environment, it is usually necessary to carry out preliminary treatment of domestic sewage. Domestic sewage is wastewater discharged from residents' daily lives. It mainly comes from residential and public buildings, such as residences, institutions, schools, hospitals, shops, public places and industrial toilets, etc., which often contain food residues.

[0003] In the process of treating domestic sewage, food residues are often filtered through filtering devices. However, traditional filtering devices require manual regular removal of food residues after intercepting them. When food residues accumulate in front of the filter for a long time, the filtration of water will be slowed down, thereby affecting the filtration effect. In addition, food residues are easy to clog the filter holes and are not easy to pour out. At the same time, some filters are in the shape of a collection frame, which can be directly connected to the food residues and taken out together, making it easier to clean up the food residues. However, during the detachment process of the filter, the upper water inlet is not blocked, which can easily cause the residues to directly enter the drain outlet. Utility Model Content

[0004] The utility model aims to provide a sewage treatment device for environmental protection engineering, so as to solve the problem that when food residues accumulate in front of the filter, the filtration of water will be slowed down, manual regular cleaning is required, and the upper water inlet is not blocked during the detachment process of the filter.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage treatment device for environmental protection engineering, comprising a shell, a filtering mechanism connected to the shell, the filtering mechanism comprising a fence plate, a truncated fence plate rotatably connected inside the shell, an embedded plate for shielding the fence hole of the fence plate slidably connected to the bottom end of the fence plate, an electric push rod for controlling the rotation of the fence plate is installed between the shell and the fence plate, a conflict wheel for conflicting with the embedded plate is provided inside the shell, a water inlet for communicating with the top of the fence plate is provided at the top of the shell, a drain port for communicating with the bottom of the fence plate is provided at the bottom of the shell, and a slag discharge port for communicating with the top of the fence plate is provided at the bottom of the shell;

[0006] The embedded plate is connected to an intercepting mechanism, and the outer shell is provided with an intercepting plate for sliding cutoff at the water inlet. The bottom end of the intercepting plate is fixedly connected to a sliding rod for sliding with the outer shell, and the inner wall of the outer shell is slidably connected to a slider. A second spring is installed between the bottom end of the slider and the outer shell, the resistance wheel is rotatably connected to the slider, and the bottom end of the sliding rod is fixed to the slider.

[0007] As a preferred technical solution of the utility model, the grid groove of the fence board is trapezoidal in structure, and one end of the embedded plate connected to the grid groove is also trapezoidal in structure, so that the embedded plate can be easily inserted into the grid groove of the fence board, thereby making the surface of the fence board smooth and facilitating food residues to slide off when the fence board is tilted.

[0008] As a preferred technical solution of the utility model, the trapezoidal bottom angle of the embedded plate and the grid groove is smaller than the trapezoidal bottom angle of the grid groove of the fence plate, so that a shear force is formed between the embedded plate and the fence plate, which can prevent food residues from being retained on the grid mouth, thereby facilitating cutting.

[0009] As a preferred technical solution of the utility model, a sliding column is fixedly connected to the bottom end of the fence plate, and the embedded plate is slidably connected to the fence plate via the sliding column, thereby facilitating the sliding of the embedded plate.

[0010] As a preferred technical solution of the utility model, a first spring is installed between the fence plate and the embedded plate, and the first spring is movably sleeved with the sliding column to facilitate the reset of the embedded plate.

[0011] As a preferred technical solution of the utility model, a partition plate for separating the slag discharge port and the water discharge port is installed inside the shell, and the partition plate is in a "<"-shaped structure, so that water and food residues are diverted.

[0012] As a preferred technical solution of the utility model, a rubber cloth is installed between the end of the fence plate facing away from the rotating end and the partition plate, and the position where the rubber cloth is connected to the partition plate is located at the turning top of the partition plate, thereby preventing food residues from being discharged from the drain outlet.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with an electric push rod, a fence plate and an embedded plate. Domestic sewage is connected from the water inlet, and food residues are intercepted and filtered through the fence plate. The electric push rod contracts at a fixed time. When the electric push rod contracts, the fence plate rotates downward, and the bottom end of the embedded plate will conflict with the abutment wheel, thereby limiting the movement of the embedded plate. The fence plate continues to rotate, so that the embedded plate slides into the fence groove of the fence plate, and the first spring contracts to make the fence plate flat, which makes it easier for food residues on the fence plate to slide off. The food residues slide into the residue discharge port through the rubber cloth and the partition plate and are discharged. After the fence plate is flipped downward, the electric push rod will extend again, thereby pushing the fence plate to reset, thereby avoiding accumulation on the fence plate and affecting the filtration of water, thereby improving the filtration efficiency.

[0015] 2. The utility model sets an intercepting plate and a sliding rod. When the fence plate is flipped downward, the bottom end of the embedded plate will contact with the contact wheel, thereby pushing the contact wheel to drive the slider to slide downward. The slider pulls the sliding rod to slide downward, the second spring is compressed, and the sliding rod drives the intercepting plate to slide, thereby blocking the water inlet, thereby preventing sewage from continuing to flow when cleaning the residue and causing a large amount of sewage to enter the residue discharge port, thereby reducing the water content in the residue and facilitating the later treatment of food residues.
