Description

Technical Field

[0001] This utility model relates to the field of oil-water separator technology, specifically an automatic slag-removing oil-water separator. Background Technology

[0002] Oil-water separators are mainly used to purify wastewater by separating grease and residue. Currently, wastewater is generally filtered through filter screens or filter plates. Solid residue will remain on the filter screens or filter plates and will clog the filter holes. The residue is not easy to remove, thus affecting the wastewater filtration efficiency. Therefore, an oil-water separator with automatic residue removal is needed. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an automatic slag-removing oil-water separator to solve the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: an automatic slag removal oil-water separator, including a purification box and a filter box installed on one side of the upper end of the purification box. The filter box is provided with an inlet pipe for introducing sewage, and the filter box is provided with a filter mechanism for filtering the introduced sewage.

[0005] The filtration mechanism includes a filter screen cylinder and a spiral discharger disposed on one side of the filter screen cylinder. The upper end of the filter screen cylinder is connected to the water inlet pipe, and one side of the filter screen cylinder is connected to the spiral discharger. The filter housing is provided with a rotating shaft inserted into the filter screen cylinder. Scrapers are distributed in a ring around the outer end of the rotating shaft. The filter housing is provided with a first motor to control the rotation of the rotating shaft, so as to scrape the filter screen cylinder with the scrapers and gradually push the filter residue into the spiral discharger, which then discharges the filter residue.

[0006] As a further embodiment of this utility model:

[0007] The spiral feeder is installed at an angle on the filter box, with one side of the spiral feeder extending out of the filter box. The spiral feeder includes a spiral tube and spiral blades rotatably installed inside the spiral tube. The bottom of the spiral tube is connected to the filter screen cylinder. A second motor that drives the spiral blades to rotate is installed at the top of the outer end of the spiral tube. A discharge pipe is connected to one side of the spiral tube in the filter box to discharge the filter residue in the spiral tube. A collection bucket for receiving filter residue is provided on one side of the filter box, and the discharge pipe guides the filter residue into the collection bucket.

[0008] As a further embodiment of this utility model:

[0009] The filter screen cylinder is arranged horizontally, and the lower end of the filter screen cylinder is provided with screen holes to retain the filter residue inside the filter screen cylinder. The scraper is a curved surface structure that rotates along the axis of the rotating shaft to gradually push the filter residue forward as the scraper rotates, thereby guiding it into the spiral tube.

[0010] As a further embodiment of this utility model:

[0011] The scraper is fixedly connected to the slide plate by the scraper rods that are distributed in a row, and is elastically mounted on the rotating shaft by the slide plate, so that the scraper elastically abuts against the inner wall of the filter screen cylinder, thereby enhancing the cleaning effect on the filter screen cylinder.

[0012] As a further embodiment of this utility model:

[0013] The rotating shaft is rotatably installed in the bearing corresponding to the filter box on one side and is connected to the first motor for transmission. The rotating shaft includes an outer cylinder installed in the filter screen cylinder and a shaft cylinder installed in the outer cylinder. The outer cylinder has several grooves distributed in a ring around the slide plate for installing the slide plate. The slide plate is provided with an anti-detachment plate in the inner cavity of the outer cylinder to prevent the slide plate from detaching from the rotating shaft through the grooves. The shaft cylinder is elastically provided with spring blocks that act on the anti-detachment plate. Several spring blocks are distributed in a ring around the slide plate to drive the slide plate to move outward, so that the scraper abuts against the inner cavity of the filter screen cylinder.

[0014] As a further embodiment of this utility model:

[0015] The spring block is slidably inserted into the groove corresponding to the shaft cylinder, and the spring block is provided with a side plate in the inner cavity of the shaft cylinder to prevent the spring block from detaching from the shaft cylinder. A shaft rod is fixedly provided in the shaft cylinder, and a limiting plate is provided in the inner groove of the spring block corresponding to the spring block. A spring is provided in the inner groove of the spring block to abut against the inner cavity of the limiting plate to push the spring block to move outward.

The outer end of the shaft cylinder is provided with an external thread corresponding to the rotating post, and the rotating post is provided with an internal thread that mates with the external thread to seal the outer end of the rotating shaft and prevent the slide plate from sliding outward and disengaging from the slide groove.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows: Wastewater is introduced into the filter screen cylinder through the inlet pipe and discharged into the purification tank through the screen holes. Filter residue remains in the filter screen cylinder. The first motor controls the rotation of the rotating shaft, which in turn drives the circularly distributed scrapers to rotate. The scrapers scrape the filter screen cylinder, pushing the filter residue forward and guiding it into the screw conveyor, from where it is discharged into the collection bucket. The scrapers in this device are curved surfaces that rotate along the axis of the rotating shaft, gradually pushing the filter residue forward as the scrapers rotate. The scrapers are also elastically mounted on the rotating shaft, allowing them to elastically adhere to the surface of the filter screen cylinder, improving the effect of scraping off the filter residue. This device, with the filter screen cylinder and screw conveyor working together, achieves automatic collection and discharge of filter residue, improving the wastewater purification efficiency.

[0029] The filter screen cylinder 3 is arranged horizontally, and the lower end of the filter screen cylinder 3 is provided with screen holes to retain the filter residue inside the filter screen cylinder 3. The scraper 51 is a curved surface structure that rotates along the axis of the rotating shaft 5, so as to push the filter residue forward step by step with the rotation of the scraper 51, thereby guiding it into the spiral tube 41.

[0030] In this embodiment, the scraper 51 is fixedly connected to the slide plate 54 by the scraper rods 53 that are distributed in a dispersed manner, and is elastically mounted on the rotating shaft 5 by the slide plate 54, so that the scraper 51 elastically abuts against the inner wall of the filter screen cylinder 3, thereby enhancing the cleaning effect on the filter screen cylinder 3.

[0031] The rotating shaft 5 is rotatably installed in the bearing corresponding to the filter box 2 on one side and is connected to the first motor 52 for transmission. The rotating shaft 5 includes an outer cylinder 55 installed in the filter screen cylinder 3 and a shaft cylinder 56 installed in the outer cylinder 55.
