Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to an oil-water separator for sewage treatment. Background Art

[0002] Sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment. Industrial sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: floating and suspended large and small solid particles, colloidal and gelatinous diffusions and pure solutions.

[0003] At present, oil-water separators are needed in the sewage treatment process. The existing oil-water separators are prone to clogging, which affects the separation effect. Secondly, the sediment is not easy to clean, resulting in low maintenance efficiency.

[0004] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created, and a sewage treatment oil-water separator is provided to solve the above-mentioned problems.

[0007] As a preferred embodiment of the oil-water separator for sewage treatment, a hanging ring is provided on the residue isolation grid.

[0008] By adopting the above scheme, the residue isolation grid contains a plurality of micropores, and the micropores are used to isolate the residue and avoid clogging the drain pipe. Secondly, the residue isolation grid can be lifted by the lifting ring to clean the residue.

[0009] As a preferred implementation of an oil-water separator for sewage treatment, the water retaining mechanism comprises an electric cylinder, and a water retaining plate is provided on the output end of the electric cylinder.

[0010] As a preferred embodiment of an oil-water separator for sewage treatment, the electric cylinder is fixed on a main body, a guide groove is provided in the main body corresponding to the water baffle plate, and the water baffle plate is slidably fitted in the guide groove.

[0011] By adopting the above solution, the water baffle is used to control the liquid overflow and prevent the sewage from flowing out while being input.

[0012] As a preferred embodiment of an oil-water separator for sewage treatment, two limit rings are slidably fitted on the output end of the driving motor, and the limit ring is fitted with a first double-headed threaded rod. A channel is provided at the output end of the driving motor corresponding to the first double-headed threaded rod, and the first double-headed threaded rod is slidably fitted in the channel, a magnetic ring is provided between the two limit rings, and the steel belt ring is magnetically fitted with the magnetic ring.

[0013] By adopting the above scheme, the magnetic ring rotates synchronously with the driving motor to realize the circulation of the steel belt ring. The density of oil in sewage is smaller than that of water. Therefore, oil is lighter than water and will float on the surface of the water. The steel belt ring passes through the water surface. When the steel belt ring circulates and contacts the floating oil, the oil will adhere to the surface of the steel belt ring and be separated.

[0014] As a preferred embodiment of a sewage treatment oil-water separator, the limiting guide mechanism includes a frame, a second double-headed threaded rod is provided on the frame, a pulley is provided on the second double-headed threaded rod, and the wall surface of the steel belt ring is in contact with the pulley.

[0017] As a preferred embodiment of an oil-water separator for sewage treatment, there are two oil scraping mechanisms, which are arranged in a mirror image.

[0018] By adopting the above scheme, the oil scraper plate can scrape off the oil adhering to the surface of the steel belt ring, and the scraped oil will flow into the oil collecting box to be collected and finally discharged through the oil drain hole.

[0019] After adopting the above technical scheme, the beneficial effects of the utility model are: 1. The equipment has a simple structure and a good oil-water separation effect. Secondly, the sediment is easy to clean, which solves the problem of blockage.

[0020] 2. Sewage flows in through the input pipe. The density of oil in sewage is smaller than that of water. Therefore, oil is lighter than water and will float on the surface of water. When the magnetic ring rotates synchronously with the drive motor, the circulation of the steel belt ring can be realized. As the steel belt ring circulates and contacts the floating oil, the oil will adhere to the surface of the steel belt ring and be separated. The adhered oil will be scraped off when passing through the oil scraper plate. The scraped oil will flow into the oil collecting box and be collected centrally. The reciprocating cycle realizes the separation of oil and water.

[0021] 3. The liquid level sensor detects the change of liquid level. The electric cylinder drives the water baffle to lift and discharge part of the liquid to avoid the problem of excessive liquid level.

[0022] 4. The residue isolation grid contains a number of micropores to achieve residue isolation and avoid clogging the drain pipe. Secondly, the residue isolation grid can be lifted through the lifting ring to achieve residue cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] A sewage input pipe 11 is disposed at one end of the main body 1 , a liquid output pipe 12 is disposed at the other end, a drainage pipe 13 is disposed at the bottom of the main body 1 , and a valve body 14 is disposed on the drainage pipe 13 .

[0035] Wherein, a hanging ring 31 is arranged on the residue isolation grid 3 .

[0036] Furthermore, the residue isolation grid 3 contains a plurality of micropores to achieve residue isolation. When the interior of the main body 1 needs to be cleaned, the valve body 14 is opened and the liquid will flow out through the drain pipe 13, while the residue will be retained on the residue isolation grid 3. The residue isolation grid 3 can be lifted by the lifting ring 31 to achieve the cleaning of the residue.

[0037] The water retaining mechanism comprises an electric cylinder 4 , and a water retaining plate 41 is arranged on the output end of the electric cylinder 4 .

[0038] The electric cylinder 4 is fixed on the main body 1 , and a guide groove 15 is provided in the main body 1 corresponding to the water baffle plate 41 , and the water baffle plate 41 is slidably fitted in the guide groove 15 .

[0039] Furthermore, the liquid level sensor 2 detects the change of the liquid level, and the electric cylinder 4 drives the water baffle 41 to lift, and some liquid can be discharged to avoid the problem of excessive liquid level.

[0040] like Figure 5 As shown, two limit rings 51 are slidably fitted on the output end of the driving motor 5, and the limit ring 51 is fitted with a first double-headed threaded rod 51. A channel is provided at the output end of the driving motor 5 corresponding to the first double-headed threaded rod 51, and the first double-headed threaded rod 51 is slidably fitted in the channel. A magnetic ring 53 is provided between the two limit rings 51, and the steel belt ring 6 is magnetically fitted with the magnetic ring 53.

[0041] Furthermore, both ends of the first double-headed threaded rod 51 are threadedly matched with nuts, and the first double-headed threaded rod 51 cooperates with the nuts to achieve the fixation of the limiting ring 51 .

[0042] like Figure 6 As shown, the limiting guide mechanism includes a frame body 7, on which a second double-headed threaded rod 71 is provided, on which a pulley 72 is provided, and the wall surface of the steel belt ring 6 contacts and cooperates with the pulley 72.

The adhered oil will be scraped off when passing through the oil scraper plate 81, and the scraped oil will flow into the oil collecting box 8 and be collected centrally, and the oil-water separation can be realized by repeating the cycle.
