Description

Technical Field

[0001] The utility model relates to the technical field of oil residue separation, in particular to an oil residue scraping device used in an oil and residue separation tank. Background Art

[0002] The main components of catering wastewater are leftover food and water, with starch, dietary fiber, animal fat and other organic matter as the main components. It has the characteristics of high nutritional value, high water content and high oil content. Therefore, in order to avoid the surrounding environment from being polluted by catering wastewater, it is necessary to build a wastewater treatment system. In this system, the oil and slag separator is the key equipment to remove oil residue and realize oil-water separation.

[0003] The working principle of the oil and slag separation tank is as follows: wastewater enters the tank from the water inlet and flows through the tank at a low horizontal flow rate. During the flow, the oil slag with a density less than that of water floats to the surface, and the water is discharged from the outlet on the other side, thereby removing the oil slag from the wastewater. The solid residues and oil slag that float to the surface need to be cleaned manually, which is inconvenient to operate and easily affects the efficiency of oil slag cleaning and the quality of the effluent water.

[0004] At present, the filter tank of the device for cleaning the oil residue is placed horizontally, and automatic external discharge cannot be realized. The method of cleaning the oil residue is mainly manual cleaning, using salvage tools to manually clean the oil residue, which is inefficient. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide an oil residue scraping device for an oil and residue separation tank. Mechanical residue cleaning can be achieved through the setting of a rotary scraping mechanism. At the same time, the inclination of the oil residue filtering tank can be utilized to achieve the purpose of automatic discharge of oil residue without manual cleaning.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oil-slag scraping device for an oil-separating and slag-trapping tank, comprising an oil-slag filtering trough and a scraping mechanism, wherein the oil-slag filtering trough is arranged on a wall panel on one side of a water inlet of the oil-separating and slag-trapping tank, and is located above the water inlet of the oil-separating and slag-trapping tank, and the scraping mechanism is arranged above the oil-separating and slag-trapping tank.

[0007] Furthermore, the oil residue filter trough is composed of a bottom plate, a side plate, and an inclined plate. The bottom plate is perpendicular to the wall plate, the side plate is perpendicular to the bottom plate, and is fixedly connected to the right side of the bottom plate. An oil residue filter trough notch is provided at the top end of the side plate, and the inclined plate is located at the top end of the side plate and is fixedly connected to the top end of the side plate.

[0008] Furthermore, the side plate is made of steel plate, is in a right-angled trapezoid, and is connected to the right side of the bottom plate by welding.

[0009] Furthermore, the inclined plate is made of a steel plate, is rectangular, and is connected to the top edge of the side plate by welding;

[0010] Furthermore, the bottom plate is made of steel plate and is rectangular.

[0011] Furthermore, the bottom plate has an inclined slope, and the inclined slope is ≥1:5, where the inclined slope is the ratio of the vertical height of the slope to the horizontal width. Compared with the horizontally arranged bottom plate of the trough, the bottom plate with an inclined slope is more conducive to the gravity discharge of the oil residue in the trough, and reduces the solidification and hardening of the oil residue in the trough.

[0012] Furthermore, the scraping mechanism is a rotary scraping mechanism, which is composed of a rotating part, a disc and an oil-slag scraping plate. The rotating part includes a shaft, a shaft seat and a reducer. Discs are installed at both ends of the shaft. The shaft seat is fixed on the top of the wall of the oil-separating and slag-separating tank. Rolling bearings are mounted on both ends of the shaft and placed on the shaft seat. The center line of the shaft is the intersection of a plane passing through the center line of the inclined plate and perpendicular to the inclined plate and a horizontal plane determined by the shaft installation height. The shaft is connected to the reducer.

[0013] Furthermore, the shaft and the reducer are directly sleeved together via sleeves respectively machined on the output shaft of the reducer and the shaft.

[0014] Furthermore, a plurality of angle steel components and bolt holes are evenly arranged on the 3 / 4 radius circumference of the disc, one side of the angle steel component is fixedly mounted on the bolt hole by bolts, and the other side of the angle steel component is connected to the oil residue scraper plate.

[0015] Furthermore, the oil-slag scraper plate is composed of an upper plate and a lower plate, one end of the upper plate is fixed to the angle steel component by bolts, and the other end is fixedly connected to the lower plate by bolts.

[0016] Furthermore, the upper plate and the lower plate are fixedly connected by bolt connection or bonding.

[0017] The upper plate of the oil scraper plate is fixed to the other side of the angle steel component by bolts, thereby connecting the oil scraper plate to the disc. When the rotary scraper mechanism is in operation, the transmission component drives the disc to rotate, and the rotation of the disc drives the oil scraper plate to rotate, thereby realizing the oil scraper operation of the oil scraper plate.

[0018] The upper plate is a steel plate, and its length is determined according to the distance between the center line of the shaft and the center line of the inclined plate, the diameter of the disc, and the length of the lower plate. It should be ensured that when the rotary scraper mechanism is in operation, the end of the lower plate can touch the inclined plate.

[0019] Furthermore, the upper plate is a steel plate or a plastic plate, and the lower plate is a thick rubber plate. The rubber material has a certain softness. When the oil residue scraper plate runs onto the inclined plate, it can ensure that the lower plate can move closely against the surface of the inclined plate, effectively preventing the oil residue from falling back into the water surface.

[0020] Furthermore, the end of the lower plate is a wedge-shaped structure, which helps to reduce the contact area between the end of the lower plate and the inclined plate, thereby reducing the scraping resistance.

[0021] Furthermore, the inclined plate and the side plate form an angle of 45° to 90°. Through the above structural design, when the scraping plate of the rotary scraping mechanism rotates to the inclined plate position, the oil residue can be slowly scraped into the oil residue filter tank along the surface of the inclined plate, effectively preventing the oil residue at the notch position of the oil residue filter tank from falling and affecting the scraping effect of the rotary scraping mechanism.

[0022] Furthermore, it also includes a slag retaining plate, which is arranged parallel to the wall panel on one side of the oil-sediment separator and slag separator water outlet. The top of the slag retaining plate is flush with the top of the wall panel on one side of the oil-sediment separator and slag separator water outlet, and the bottom is lower than the water outlet. It is used to prevent floating oil residue on the water surface from flowing out of the oil-sediment separator and slag separator water, thereby ensuring the removal effect of the oil-sediment separator and slag separator.

[0023] The principle of the utility model is as follows: the residual oil residue in the wastewater in the oil-separating and residue-separating tank floats up, the rotary scraping mechanism operates, the scraping plate hits the inclined plate, and the lower plate moves closely against the surface of the inclined plate, so that the scraping plate scrapes the residual oil residue into the oil-separating and residue filtering tank, and utilizes gravity and a bottom plate with an inclined slope to discharge the residual oil residue by gravity.

[0024] Compared with the prior art, the oil residue scraping device of the utility model has the following beneficial effects:

[0025] 1. This device can realize the mechanical slag removal of the oil and slag separation tank, is easy to operate, and improves the efficiency of oil and slag cleaning.

[0026] 2. The bottom plate of the oil residue filter tank is designed with an inclined slope, which is more conducive to the gravity discharge of the oil residue in the tank compared to the horizontally arranged tank bottom plate, reducing the solidification of the oil residue in the tank; the oil residue is scraped off by the rotary scraping mechanism without manual salvage; the oil residue scraping plate set on the rotary scraping mechanism can effectively ensure the oil residue scraping frequency and effect of the oil residue scraping device.

[0027] 3. The scraper plate is composed of two plates, the lower plate is made of thick rubber plate, which can ensure that the lower plate can move closely against the surface of the inclined plate, so as to facilitate the scraping of residual oil residue to the oil residue filter tank, and effectively prevent the oil residue from falling back to the water surface. The end of the lower plate is processed into a wedge-shaped structure, which helps to reduce the contact area between the end of the lower plate and the inclined plate, and reduce the scraping resistance.

[0028] 4. The device has a simple structure, easy operation, and safe and reliable technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Furthermore, the bottom plate 1 , the side plate 2 , and the inclined plate 3 are all made of steel plates, wherein the bottom plate 1 and the inclined plate 3 are rectangular, and the side plate 2 is a right-angled trapezoid.

[0038] Furthermore, the bottom plate 1 has an inclined slope, the inclined slope is ≥ 1:5, wherein the inclined slope is the ratio of the vertical height of the slope to the horizontal width.

[0039] Furthermore, the scraping mechanism is a rotary scraping mechanism, which is composed of a rotating part, a disc 5 and an oil-slag scraping plate 6.

[0043] The upper plate 7 of the oil scraper plate 6 is fixed to the other side of the angle steel component 10 by bolts 8, thereby connecting the oil scraper plate 6 to the disc 5. When the rotary scraper mechanism is running, the rotating component drives the disc 5 to rotate, and the rotation of the disc 5 drives the oil scraper plate 6 to rotate, thereby realizing the oil scraper operation of the oil scraper plate 6.
