Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge and oil removal device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of removing pollutants from wastewater using physical, chemical, and biological methods to meet water quality standards for discharge or reuse. Existing wastewater treatment systems for removing sludge and oil often fail to thoroughly treat oil and sludge, resulting in incomplete separation and contamination of the wastewater in subsequent treatment stages, thus affecting the overall treatment effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sludge and oil removal device for sewage treatment.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] Furthermore, the cleaning unit includes a motor located at the upper end of the slag removal box, a rotating shaft fixedly connected to the output end of the motor and located inside the slag removal box, and scrapers evenly distributed on the rotating shaft; the end of the scraper away from the rotating shaft matches and contacts the inner surface of the conical filter screen.

[0007] Furthermore, the scraper is provided in four pieces and is inclined in the same direction.

[0008] Furthermore, a collar is fixedly connected to the upper end of the oil pump; a threaded rod is threadedly connected to the support rod; the threaded rod is sleeved in the collar and can rotate relative to it.

[0009] Furthermore, a baffle is vertically fixed to the lower end of the oil removal tank near the sewage outlet pipe; the horizontal height of the baffle is higher than the water outlet end of the second pipe.

[0010] Furthermore, a buffer plate is fixedly connected to the outlet end of the second pipe via a connecting rod.

[0011] The beneficial effects of this utility model are:

[0012] (1) By setting up a cleaning section, the slag on the conical filter screen in the slag removal box can be scraped off and fall into the first pipe and collected by the screw conveyor, effectively removing the slag from the sewage; by setting up an oil removal box, the oil in the slag removal sewage flowing into the second pipe can be treated, causing it to float and be pumped by an oil pump into the oil delivery pipe connected by a hose for further treatment, effectively removing the oil from the sewage; the oil pump can also be height adjusted by a threaded rod to prevent sewage from being pumped out.

[0013] (2) This application first removes the sludge in the sewage and then removes the oil, thus completely separating the oil and sludge in the sewage and ensuring the effectiveness of sewage treatment. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Reference Figure 1-2As shown, a wastewater treatment sludge and oil removal device includes a sludge removal box 1, a conical filter screen 2 fixedly connected inside the sludge removal box 1, a cleaning part 3 whose upper end is detachably connected to the upper end of the sludge removal box 1 and whose lower two sides are in contact with the conical filter screen 2, a first pipe 4 whose upper end is connected to the bottom of the conical filter screen 2 and whose lower end extends out of the lower end of the sludge removal box 1 and is fixedly connected to an auger 5, a second pipe 6 whose upper end is connected to the lower end of the sludge removal box 1, an oil removal box 7 located below the sludge removal box 1 and into which the second pipe 6 extends, a wastewater outlet pipe 8 connected to the side away from the second pipe 6 and located at the end of the sludge removal box 1, and an oil pump 10 installed above the sludge removal box 1 via a support rod 9; a wastewater inlet pipe 11 is connected above the sludge removal box 1; and the oil pump 10 is connected to an oil delivery pipe 12 via a hose.

[0022] It should be noted that the slag removal box 1 facilitates the installation of other components; the conical filter screen 2, in conjunction with the cleaning section 3, can remove slag from the wastewater containing slag; the first pipe 4, connected to the auger, can output the slag from the slag removal box 1 for collection; the second pipe 6 is used to transport the slag removal wastewater to the oil removal box 7 for oil removal; the oil pump 10, connected via the support rod 9, can be easily adjusted in height to ensure the removal of oil from the upper part of the oil removal box 7; the wastewater inlet pipe 11 is used for wastewater to enter the slag removal box 1; and the oil delivery pipe 12 is used for the treatment of the extracted oil.

[0023] Specifically, the cleaning unit 3 includes a motor 301 located at the upper end of the slag removal box 1, a rotating shaft 302 fixedly connected to the output end of the motor 301 and located inside the slag removal box 1, and scrapers 303 evenly distributed on the rotating shaft 302. The end of the scraper 303 away from the rotating shaft 302 matches and contacts the inner surface of the conical filter screen 2. The motor 301 can drive the scraper 303 on the rotating shaft 302 to rotate, scraping the slag on the conical filter screen 2 and causing it to fall into the first pipe 4 and be collected by the auger 5.

[0024] In this application, four scrapers 303 are provided and are inclined in the same direction, which makes it easier for the slag to fall into the first pipe 4.

[0025] Specifically, in order to facilitate the adjustment of the height of the oil pump 10 and prevent the pumping of sewage, a collar 13 is fixedly connected to the upper end of the oil pump 10; a threaded rod 14 is threadedly connected to the support rod 9; the threaded rod 14 is sleeved in the collar 13 and can rotate relative to it.

[0026] Specifically, to prevent oil in the sewage entering the second pipe 6 from being discharged through the sewage outlet pipe 8 before it floats to the surface, a baffle 15 is vertically fixed to the lower end of the oil tank 7 near the sewage outlet pipe 8; the horizontal height of the baffle 15 is higher than the water outlet end of the second pipe 6. The baffle 15 can ensure that the sewage flows smoothly at the sewage outlet pipe 8.

[0027] Specifically, the outlet end of the second pipe 6 is fixedly connected to a buffer plate 17 via a connecting rod 16, and the buffer plate 17 can ensure the stability of the water flow.

[0028] The working principle of this utility model:

[0029] During wastewater sludge and oil removal, the cleaning unit 3 scrapes off the sludge on the conical filter screen 2 in the sludge removal box 1 and collects it in the first pipe 4 via the screw conveyor 5, effectively removing the sludge from the wastewater. The oil removal box 7 treats the oil in the sludge removal wastewater flowing into the second pipe 6, causing it to float to the surface and be pumped by the oil pump 10 into the oil delivery pipe 12 connected by a flexible hose for further processing, effectively removing the oil from the wastewater. The oil pump 10 can also be height-adjusted via the threaded rod 14 to prevent the pump from drawing out wastewater.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
