Description

Technical Field

[0002] Domestic sewage is the wastewater discharged in residents' daily life, mainly from residential buildings and public buildings, such as houses, institutions, schools, hospitals, stores, public places and the toilets of industrial enterprises. Domestic sewage contains various pollutants, including food residues, soaps and detergents, as well as solid particles such as sediment, hair and paper scraps. For environmental protection and water conservation, a sewage solid-liquid separation device is used to separate the solid substances and the liquid part in the sewage, so that the separated sewage can be discharged into a filtration tank and filtered and purified to form secondary water.

[0003] Nowadays, solid-liquid separation devices usually use the spiral extrusion method for solid-liquid separation. The solids in the sewage are extruded and separated by a screw rod. During long-term use, the liquid outlet holes and the filter screen of the separation device will be blocked by impurities. When dredging the filter screen, usually clean water is transported into the inner cavity of the solid-liquid separation device for stirring. This stirring method can clean the inner cavity of the solid-liquid separation device, but it is difficult to remove the impurities blocking the filter screen and the liquid outlet holes. Therefore, an efficient domestic sewage solid-liquid separation device is proposed. Summary of the Utility Model

[0026] Embodiment

[0027] Referring to Figures 1 - 4 , which is an embodiment of the present utility model, there is provided an efficient domestic sewage solid-liquid separation device, including: a separation unit 100 and a flushing unit 200;

[0028] Among them, the separation unit 100 includes a separation cylinder 101 and a sleeve 102 fixedly sleeved on the separation cylinder 101. There is a gap between the inner cavity of the sleeve 102 and the separation cylinder 101. A plurality of water outlet holes located within the sleeve 102 are provided on one side of the separation cylinder 101. A support frame 103 is fixedly installed at the bottom on one side of the sleeve 102. A water inlet hopper 104 is fixedly communicated with one side of the separation cylinder 101. A servo motor 105 is fixedly installed at the end of the separation cylinder 101. The output end of the servo motor 105 penetrates the end of the separation cylinder 101 and is fixedly connected to a hollow screw rod 106. A sludge discharge pipe 107 is fixedly communicated with one side of the separation cylinder 101. A water outlet pipe 108 is fixedly communicated with one side of the sleeve 102;

[0029] The flushing unit 200 includes a rotating cylinder 201 slidably disposed on the inner wall of the screw rod 106. A plurality of uniformly distributed water spraying holes are provided on both the rotating cylinder 201 and one side of the screw rod 106. One end of the rotating cylinder 201 penetrates the inner wall of the separation cylinder 101 and is fixedly communicated with a water delivery pipe 202. A fixing plate 203 is fixedly connected to one side of the rotating cylinder 201. A limiting rod 204 is rotatably connected to one side of the fixing plate 203. Two threaded holes with different depths that fit the limiting rod 204 are provided at the end of the separation cylinder 101. One end of the limiting rod 204 penetrates the fixing plate 203 and is threadedly connected to one of the threaded holes.

[0030] The water inlet hopper 104 is used to discharge sewage into the separation cylinder 101. The servo motor 105 drives the screw rod 106 to rotate, and the sewage is pushed by the screw rod 106 to move in the separation cylinder 101. The sewage is discharged into the sleeve 102 through the water outlet holes of the separation cylinder 101. The liquid reaching the sleeve 102 after separation is discharged through the water outlet pipe 108. The solids doped in the sewage remain in the separation cylinder 101 and are extruded by the screw rod 106. The extruded solids are discharged through the sludge discharge pipe 107.

[0031] At this time, the water spraying holes of the screw rod 106 and the rotating cylinder 201 are staggered from each other, and there is a gap between the water spraying holes of the screw rod 106 and the rotating cylinder 201. When the screw rod 106 rotates, the sewage will not flow into the rotating cylinder 201. The rotating cylinder 201 can slide and rotate along the inner wall of the screw rod 106. The depth of the threaded hole in the direction close to the water outlet pipe 108 is deeper than that of the other threaded hole. When it is necessary to clean the separation cylinder 101, the limit rod 204 is rotated so that it is no longer located in the threaded hole with a shallower depth. Then the rotating cylinder 201 is rotated so that its limit rod 204 is aligned with the threaded hole in the direction towards the water outlet pipe 108, and the limit rod 204 is screwed into this threaded hole, so that the rotating cylinder 201 slides in the screw rod 106 towards the direction of the servo motor 105.

[0032] After the rotating cylinder 201 rotates and moves at this time, the water spraying holes of the screw rod 106 and the rotating cylinder 201 overlap each other. Then the water delivery pipe 202 is externally connected to a water pipe to deliver water source to the rotating cylinder 201. Through the water spraying holes, the inner wall of the separation cylinder 101 and the screw rod 106 can be flushed, and the water spraying holes can also flush the water outlet holes of the separation cylinder 101 to dredge the blocked water outlet holes. The screw rod 106 rotates slowly, so that the flushed sewage is discharged through the sludge discharge pipe 107 and the water outlet pipe 108. When the screw rod 106 rotates, the water spraying holes of the screw rod 106 and the rotating cylinder 201 will intermittently overlap, so that the water pressure inside the rotating cylinder 201 increases, and the pressurized water is quickly ejected through the water spraying holes, thereby being able to efficiently flush the water outlet holes of the separation cylinder 101 to improve the dredging effect. After the flushing is completed, the limit rod 204 is screwed into another threaded hole so that the water spraying holes of the screw rod 106 and the rotating cylinder 201 are staggered from each other, and then the sewage solid-liquid separation work can be carried out.

[0033] In addition, a rotating rod 205 is rotatably connected to the end of the sleeve 102. The rotating rod 205 penetrates through one end of the sleeve 102 and is fixedly connected to a gear 206. An arc-shaped opening that fits the gear 206 is formed on one side of the sleeve 102. A toothed ring 207 that meshes with the gear 206 is slidably sleeved on the separation cylinder 101. One side of the toothed ring 207 is fixedly connected to a plurality of uniformly distributed scraping plates 208. A limiting column 209 is fixedly connected to one side of the separation cylinder 101. The limiting column 209 is located between two adjacent scraping plates 208.

[0034] A gap is left between the inner cavity of the sleeve 102 and the separation cylinder 101. The scraping plates 208 and the toothed ring 207 are both located in the gap between the sleeve 102 and the separation cylinder 101. The gear 206 passes through the arc-shaped opening of the sleeve 102. By rotating the rotating rod 205, the gear 206 drives the toothed ring 207 to rotate. Thus, the toothed ring 207 can drive a plurality of scraping plates 208 to move, so that the scraping plates 208 can scrape the sludge attached to the water outlet holes of the separation cylinder 101, ensuring that no sludge and other impurities accumulate around the water outlet holes, and reducing the phenomenon of blockage of the water outlet holes. The limiting column 209 is used to limit the moving range of the scraping plates 208, so that the scraping plates 208 contact the limiting column 209 after moving a certain distance along the outer wall of the sleeve 102. Through the limiting column 209, the scraping plates 208 can always be located around the water outlet holes and will not stay at the port position of the water outlet holes, ensuring that the sewage can flow out of the water outlet holes normally.

[0035] Further, a sealing cover is provided at the bottom end of the sludge discharge pipe 107. A reflux pipe 210 is fixedly connected to one side of the separation cylinder 101. Valves are sleeved on both ends of the reflux pipe 210. A plurality of inclined plates 109 are fixedly connected to both sides of the inner wall of the water inlet hopper 104. The plurality of inclined plates 109 are arranged vertically and staggeredly. One side of the output end of the servo motor 105 is fixedly connected to a plurality of ball head rods 110. A plurality of conical blocks are fixedly connected to the spherical surface of each ball head rod 110.

[0036] A sealing cover is provided at the bottom of the sludge discharge pipe 107. During solid-liquid separation, the sealing cover is removed. When the separation cylinder 101 is being cleaned, the sewage discharged from the sludge discharge pipe 107 will gradually become clear. At this time, the sealing cover is reinstalled at the bottom end of the sludge discharge pipe 107, and the water supply pipe 202 stops supplying water. Then, the valves at both ends of the reflux pipe 210 are opened. During the rotation of the screw rod 106, the screw rod 106 will squeeze the water in the separation cylinder 101 into the reflux pipe 210, and through the reflux pipe 210, the water can be guided back to the lower part of the water inlet hopper 104 again. Through this cycle, the water consumption required for cleaning can be reduced to save water resources. During the reflux process, part of the water is discharged through the water outlet pipe 108. When no water flows out of the water outlet pipe 108, the cleaning is completed. Finally, the two valves of the reflux pipe 210 are closed;

[0037] Through multiple staggered inclined plates 109, sewage can flow evenly into the separation cylinder 101, and fixed impurities in the sewage will also mix with the sewage when passing through the inclined plates 109, so that the impurities can float in the sewage for a short time and be drawn into the screw rod 106, and evenly distributed between the spiral blades of the screw rod 106, thereby preventing impurities from being concentrated and precipitated at the bottom of the inner wall of the separation cylinder 101, causing impurities to be excessively concentrated in the water outlet at the bottom of the separation cylinder 101 during solid-liquid separation, and ultimately resulting in poor liquid discharge from the bottom water outlet. When the servo motor 105 drives the ball head rod 110 to rotate, the ball head rod 110 can impact and break larger impurities through the conical block, so as to facilitate the subsequent solid-liquid separation by the screw rod 106.

[0038] During use, when cleaning is required, the limiting rod 204 is rotated so that it is no longer located in the shallower threaded hole, and then the drum 201 is rotated to align the limiting rod 204 with the spiral hole in the direction of the water outlet pipe 108, and the limiting rod 204 is spirally connected in the spiral hole. At this time, the spiral rod 106 and the water spray hole of the drum 201 overlap each other, and then the water pipe 202 is connected to the water pipe and conveys water to the drum 201. The inner wall of the separation drum 101 and the spiral rod 106 can be washed through the water spray hole, and the blocked water outlet hole can be dredged. Then, the rotating rod 205 is rotated so that the gear 206 drives the toothed ring 207 to rotate, so that the scraper 208 can scrape out the sludge attached to the water outlet hole of the separation drum 101 to ensure that sludge and other impurities will not accumulate around the water outlet hole.

[0039] Then reinstall the sealing cover to the bottom end of the mud discharge pipe 107, and stop delivering water from the water supply pipe 202. Then open the valves at both ends of the return pipe 210. The water at the end of the separation cylinder 101 can be guided to the bottom of the water inlet bucket 104 through the return pipe 210 to reduce the amount of water required for cleaning. When no water flows out of the outlet pipe 108, close the two valves of the return pipe 210. After flushing, screw the limit rod 204 into another spiral hole so that the spiral rod 106 and the water spray hole of the rotating drum 201 are staggered with each other, and then the solid-liquid separation of the sewage can be carried out.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
