Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment and relates to an oil-water separator. Background Art

[0002] Oil-water separators are very commonly used in industrial production. During industrial production, the surfaces of machines, equipment, parts, etc. often absorb oil and dirt, and need to be cleaned. During the cleaning process, an oil-water separator is needed to remove the oil in the liquid. There are roughly three types of industrial oil-water separators: 1. Using the principle of aeration to decompose grease; 2. Using density difference to separate grease; 3. Using the principle of scraping oil to separate oil and water. According to the structure, oil-water separators include float type, turntable type, and spiral type.

[0003] At present, the more commonly used oil-water separators are: belt-type oil scrapers or rotary oil scrapers. For example, a kind of oil-water separator on a machine tool disclosed in a Chinese patent document [Announcement No.: CN 207286761U] includes a reduction motor, a motor cover, an oil suction plate, an oil scraper plate, an oil outlet plate, an oil filter box and an oil receiving box; the oil suction plate is connected to the motor shaft of the reduction motor, and the reduction motor drives the oil suction plate to rotate through the motor shaft; there are two oil scrapers, which are respectively installed on the left and right sides of the oil suction plate; the oil outlet plate is installed below the oil scraper plate and fixed to the lower end of the oil scraper plate by screws; the oil filter box is installed below the oil outlet of the oil outlet plate and is fixedly connected to the motor cover, an oil outlet slot is provided at the upper left end of the oil filter box, a partition is provided in the middle of the oil filter box, and the oil receiving box is installed below the oil outlet slot on the oil filter box to receive the oil flowing out of the oil outlet slot on the oil filter box.

[0004] Before using the above-mentioned oil-water separator, the position of the oil scraper plate needs to be adjusted so that the oil scraper plate is close to the oil suction plate. Since the oil scraper plate, the oil outlet plate and the oil suction plate are all covered by the motor cover, the entire motor cover needs to be removed when adjusting the position of the oil scraper plate. However, the motor cover is large in size and heavy in weight, and it is inconvenient to disassemble and assemble, which makes it inconvenient to adjust the position of the oil scraper plate. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes an oil-water separator, which solves the technical problem of how to make the position of the oil scraper plate easy to adjust.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] An oil-water separator comprises a motor, an oil suction pan is fixedly connected to the rotating shaft of the motor, a protective cover is provided on the outer cover of the oil suction pan, an inclined oil outlet plate is fixed in the protective cover, the front side of the oil suction pan is embedded in the rear end of the oil outlet plate, the front end of the oil outlet plate extends out from the front side wall of the protective cover, and left and right adjustable oil scraper plates are respectively fixedly connected to the upper surface of the oil outlet plate on the left and right sides of the oil suction pan, and the characteristic is that a window is opened on the front side wall of the protective cover above the oil outlet plate, the window extends upward and passes through the upper side wall of the protective cover, the width of the window in the left and right directions is greater than the sum of the widths of the two scraper plates in the left and right directions, and a cover for closing the window is detachably fixedly connected to the protective cover.

[0008] The protective cover is fixedly connected to the water tank, and the lower side of the oil suction plate extends into the liquid. The motor works to rotate the oil suction plate, and the oil in the liquid will be adsorbed on the surface of the oil suction plate. As the oil suction plate rotates, the oil on the oil suction plate is scraped off by the oil scraper plate, and the oil enters the oil outlet plate and slides out of the protective cover along the oil outlet plate. Since the window is arranged on the front side wall of the protective cover and is located above the oil outlet plate, that is, the position of the window corresponds to the position of the oil scraper plate, and the window extends upward and penetrates the upper side wall of the protective cover, and the width of the window in the left and right directions is greater than the sum of the widths of the two oil scrapers in the left and right directions, the position and size of the window are suitable for adjusting the oil scraper plate through the window. When it is necessary to adjust the left and right positions of the oil scraper plate so that the oil scraper plate is more closely attached to the oil suction plate, the cover is removed to expose the window, and then the position of the oil scraper plate is adjusted through the window. After the adjustment is completed, the cover can be fixed again. Compared with the entire protective cover, the cover is small in size and light in weight, and it is more convenient to disassemble and assemble, so that the position of the oil scraper plate is convenient to adjust.

[0009] In the above-mentioned oil-water separator, the oil scraper plate includes an oil scraper portion abutting against the oil suction plate, a fixed portion abutting against the oil outlet plate, and a connecting portion between the fixed portion and the oil scraper portion, and the connecting portion is inclined toward one side of the oil suction plate relative to the fixed portion. As the oil suction plate rotates, the oil scraper portion scrapes the oil on the oil suction plate, and the scraped oil slides down the oil outlet plate along the connecting portion. The connecting portion has a guiding effect on the oil, so that the oil slides smoothly down the oil outlet plate. At the same time, the connecting portion can also increase the elasticity of the oil scraper plate, so that the oil scraper portion is more closely attached to the oil suction plate, thereby improving the oil scraping effect.

[0010] In the above oil-water separator, the fixing part is fixedly connected to the oil outlet plate by means of an adjusting screw, and a strip-shaped adjusting hole extending in the left-right direction is provided on the fixing part, and the adjusting screw is passed through the adjusting hole. When the left-right position of the oil scraper plate needs to be adjusted, the adjusting screw is loosened, and then the oil scraper plate is slid left-right, and the adjusting screw slides in the adjusting hole. When the position of the oil scraper plate is appropriate, the adjusting screw is tightened again, and the adjustment is convenient.

[0011] In the above oil-water separator, the cover includes a vertical portion covering the front side wall of the protective cover, a horizontal portion covering the upper side wall of the protective cover, and an inclined portion located between the vertical portion and the horizontal portion, and the inclined portion is arranged to be inclined downward relative to the horizontal portion. The cover forms a chamfered structure at the inclined portion, thereby reducing the weight of the cover and making it easy to disassemble and assemble the cover.

[0012] In the above oil-water separator, the motor is fixedly connected to the protective cover, the outer cover of the motor is provided with a motor cover, and the motor cover is provided with a speed knob and a switch button. The switch button is used to turn on and off the motor, and the speed knob is used to adjust the motor speed. The speed knob and the switch button are arranged on the motor cover to facilitate the operation of turning on and off the motor and adjusting the motor speed.

[0013] In the above oil-water separator, an oil collecting box is arranged in front of the protective cover and below the oil outlet plate. The oil that slides out of the oil outlet plate enters the oil collecting box, and the oil collecting box makes it easy to collect the oil.

[0014] In the above oil-water separator, the cover is fixedly connected to the protective cover by a plurality of fixing screws. A plurality of fixing holes corresponding to the fixing screws are arranged on the edge of the cover, and the fixing screws are threadedly connected to the protective cover after passing through the corresponding fixing holes. When the left and right positions of the oil scraper need to be adjusted, all the fixing screws are screwed out, and then the cover is removed. After the adjustment is completed, the cover is replaced, and then the fixing screws are tightened again.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] A window is provided on the protective cover, and a detachable cover is provided at the window, so that the oil scraper is easy to debug and the protective function of the protective cover is guaranteed at the same time. The oil scraper includes a fixed part, an oil scraper part and an inclined connecting part, which increases the elasticity of the oil scraper and improves the oil scraping effect. The cover includes a vertical part, a horizontal part and an inclined part, which reduces the weight and makes the cover easy to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS
