[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly from residential buildings and public buildings, such as residences, government offices, schools, hospitals, shops, public places and toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and enteric infectious viruses, etc.). The organic matter in domestic sewage is extremely unstable and easily decomposes to produce a foul odor. Bacteria and pathogens multiply in large numbers with organic matter in domestic sewage as nutrition, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] At present, the anti-clogging effect of common domestic sewage treatment equipment is poor. During the sewage treatment process, due to the large number of solid particles in domestic sewage, the filter is easily clogged. Therefore, users are required to frequently remove the filter for cleaning, which seriously reduces the efficiency of sewage treatment and brings great inconvenience to users. Summary of the invention

[0004] The purpose of the present invention is to provide a sewage treatment device.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

DETAILED DESCRIPTION

[0016] The following are examples and the attached Figure 1 , the technical solution of the present invention is further specifically described.

[0017] A sewage treatment device, comprising a box 1:

[0018] A rectangular frame I2 is provided on the inner wall of the box body 1, wherein a perforated plate 3 is provided at the bottom of the rectangular frame I2, and a sealing layer is provided between the perforated plate 3 and the rectangular frame I2, one end of the perforated plate 3 is fixed to the inner wall of the box body 1 through a rotating shaft 4, wherein the left half of the side wall of the perforated plate 3 is a solid structure, and a base 5 located below the perforated plate 3 is provided at the bottom of the box body 1, and a hydraulic rod I6 whose output shaft abuts against the bottom end surface of the perforated plate 3 is provided in the base 5, wherein the cross section of the base 5 is a right triangle, and the inner bottom of the box body 1 is divided into a liquid storage chamber 7 and a slag discharge chamber 8 by the base 5, wherein the solid structure side wall of the perforated plate 3 is located directly above the slag discharge chamber 8;

[0019] A rectangular frame II9 is ​​arranged above the rectangular frame I2, wherein an L-shaped plate 10 is arranged inside the rectangular frame II9, the bottom end of the L-shaped plate 10 is located in the opening of the rectangular frame I2 and is against the top surface of the orifice plate 3, a screw rod 11 is arranged inside the rectangular frame II9, which passes through the L-shaped plate 10 and is driven by a motor 12, and a mounting plate 13 is also arranged on the top of the rectangular frame II9, wherein the mounting plate 13 is driven by a hydraulic rod II14.

[0020] In this embodiment, the outer wall of the rectangular frame I2 is fixedly connected to the corresponding inner wall of the box body 1, wherein a circle of strip grooves for accommodating a sealing layer is arranged around the bottom end surface of the rectangular frame I2, and the sealing layer is made of rubber material.

[0021] A slag discharge pipe 15 connected to the slag discharge chamber 8 and a drainage pipe 16 connected to the liquid storage chamber 7 are respectively arranged at the bottom of the side wall of the box body 1, and a water inlet pipe 17 located above the rectangular frame I2 is also arranged at the top of the side wall of the box body 1, wherein the installation position of the water inlet pipe 17 is opposite to the position at the side wall of the solid structure in the orifice plate 3.

[0022] In this embodiment, a slide rod is provided in the rectangular frame II9 and passes through the through hole on the side wall of the L-shaped plate 10. When the screw rod 11 rotates in the screw hole on the L-shaped plate 10 to drive it to move left and right, the through hole on the L-shaped plate 10 will slide on the slide rod to prevent the L-shaped plate 10 from rotating together with the screw rod 11 and affecting its displacement.

[0023] like Figure 1 As shown, a lug is provided on the output shaft of the hydraulic rod 16, which is against the bottom end surface of the orifice plate 3, wherein the lug is located at the bottom of the side wall of the solid structure of the orifice plate 3, and a water retaining curtain 18 with the bottom end extending into the liquid storage chamber 7 is hung at the bottom of the side wall of the solid structure of the orifice plate 3. The water retaining curtain 18 prevents the liquid dripping from the aperture of the orifice plate 3 from being blown into the slag discharge chamber 8.

[0024] When in use, wastewater enters the top of the orifice plate 3 on the right side of the L-shaped plate 10 through the water inlet pipe 17, wherein the liquid is drained out through the aperture on the right side wall of the orifice plate 3, while impurities are accumulated above the orifice plate 3. The liquid filtered in the above process falls into the liquid storage chamber 7 and is discharged by the discharge pipe 16;

[0025] When impurities are deposited and stirred above the orifice plate 3, the hydraulic rod II14 drives the rectangular frame II9 and the L-shaped plate 10 to move upward through the mounting plate 13, wherein the motor 12 drives the screw rod 11 to drive the L-shaped plate 10 to move rightward to the rightmost position, and then the hydraulic rod II14 drives the rectangular frame II9 and the L-shaped plate 10 to move downward through the mounting plate 13, so that the L-shaped plate 10 is displaced to the top of the right end of the orifice plate 3. At this time, the motor 12 drives the screw rod 11 to drive the L-shaped plate 10 to move leftward, so that the L-shaped plate 10 in the moving process can scrape and clean the impurities deposited above the orifice plate 3, so as to collect the impurities in the temporary storage above the left side of the orifice plate 3, and then repeat the above steps to filter the wastewater;

[0026] In the above process, the solid structure side wall of the orifice plate 3 and the water retaining curtain 18 can prevent the liquid leaking from the orifice plate 3 from dripping into the slag discharge chamber 8. After the filtration is completed, the hydraulic rod I6 contracts. Then, without the squeezing and fixing of the hydraulic rod I6, the orifice plate 3 rotates counterclockwise around the rotating shaft 4 as the center, and finally rests on the top of the base 5, thereby making the orifice plate 3 tilted so that the impurities above it can flow into the slag discharge chamber 8 along the inclined surface of the orifice plate 3, so as to facilitate the discharge of impurities above the orifice plate 3. Of course, the orifice plate 3 can also be lifted up by the hydraulic rod I6 and then contracted, so that the orifice plate 3 rotates up and down reciprocatingly around the rotating shaft 4 as the center, and the counterclockwise rotating orifice plate 3 will knock on the top of the base 5, thereby shaking off the impurities above the orifice plate 3, and the impurities flow into the slag discharge chamber 8 along the top inclined surface of the orifice plate 3 at this time.

[0027] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
