Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to a petrochemical oil-water mixture sampling and separation device. Background Technology

[0002] Currently, an industrial oil-water mixture separator is a device specifically designed to separate oil and water mixtures. It typically consists of a container, one or more filters, and a pump. For example, a Chinese patent discloses an oil-water separation device for treating oil-water mixtures (publication number CN216837378U), which includes a frame and a float. The bottom of the frame is provided with support legs, and one end of the top of the frame is provided with a feed inlet. The two ends of the inside of the frame are respectively provided with a filter chamber and an oil-water settling chamber, and the filter chamber and the oil-water settling chamber are interconnected.

[0003] However, the aforementioned disclosed documents utilize a filter screen in the filter chamber to filter impurities in the oil-water mixture, preventing impurities from affecting oil-water separation. When it is necessary to clean impurities adhering to the surface of the filter screen, the mounting cover at the bottom of the filter chamber can be easily removed to allow the filter screen to be pulled out for cleaning, improving convenience during use. However, in use, this patent suffers from limitations because the filter screen is prone to clogging and difficult to clean, requiring frequent replacement, leading to reduced work efficiency and increased maintenance time. Therefore, those skilled in the art have provided a petrochemical oil-water mixture sampling and separation device to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a petrochemical oil-water mixture sampling and separation device, which solves the problem mentioned in the background technology that the filter screen is prone to clogging and difficult to clean, requiring frequent replacement, resulting in reduced work efficiency and increased maintenance time, thus limiting its application.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a petrochemical oil-water mixture sampling and separation device, including a body, with support legs fixedly installed at the four corners of the bottom surface of the body, and through-hole screw holes opened on the bottom surface of the support legs. By turning the bolts in the screw holes, the body can be fixed at the designated installation position through the support legs, ensuring that the body can operate stably in the later stage, while facilitating disassembly and relocation.

[0006] As a further technical solution of this utility model, the machine body is provided with a filter chamber and a separation chamber, and the filter chamber and the separation chamber are interconnected. The filter chamber is provided with a filter screen. The top surface of the machine body is fixed with a feed pipe that is interconnected with the filter chamber. The oil-water mixture is transported to the filter chamber through the feed pipe. Then, the filter screen is used to filter and intercept larger solid impurities contained in the oil-water mixture, thereby improving the working effect of subsequent oil-water separation.

[0007] As a further technical solution of this utility model, a cleaning component is provided above the filter screen. The cleaning component includes a hollow connecting plate above the filter screen. Scrapers are fixed on the outer walls of both the front and rear sides of the hollow connecting plate. A hollow rotating rod is fixed and connected through the outer top surface of the hollow connecting plate. A square sleeve is fixed on the outer top surface of the machine body. A rotary joint is fixed on the inner top surface of the square sleeve. One end of the hollow rotating rod extends rotatably into the interior of the square sleeve and is connected through the rotary joint. A round rod is rotatably installed on the inner side wall of the square sleeve. A bevel gear one is fixed on the outer circumferential side wall of the round rod. A bevel gear two is fixed on the outer circumferential side wall of the hollow rotating rod. Bevel gear one and bevel gear two mesh with each other. Several nozzles are symmetrically connected through the outer bottom surface of the hollow connecting plate. A vertical plate is fixed on the left end of the outer top surface of the hollow connecting plate. A drive motor is fixedly installed on the outer top surface of the machine body. One end of the round rod extends rotatably into the square sleeve. On the right outer wall, and fixedly connected to the output end of the drive motor, the outer bottom surfaces of both scrapers abut against the outer surface of the filter screen, and the outer side walls of the two scrapers, which are far apart, are inclined. A water guide pipe is fixedly connected to the top surface of the square sleeve, with one end of the water guide pipe connected to a rotary joint. During use, when the filter screen is filtering an oil-water mixture, the drive motor is controlled and activated to drive the round rod carrying the first bevel gear in a circular motion inside the square sleeve. Under the meshing connection of the first bevel gear, the second bevel gear drives the hollow rotating rod to rotate inside the filter chamber. This causes the hollow connecting plate to carry the scrapers in a circular motion on the outer surface of the filter screen, thereby scraping away impurities on the filter screen and preventing clogging caused by impurities accumulating on the filter screen for extended periods. This also prevents the need for frequent filter replacements after clogging, thus improving filtration efficiency. Before scraping, the water pipe is connected to the output pipe of the external water supply equipment. Then, the electric valve on the water pipe is opened to guide the water flow along the rotary joint and hollow rotating rod into the hollow connecting plate. The water is then discharged through several nozzles, and the water flow washes the filter during the scraping process, further preventing the possibility of clogging and improving the practicality of the device in actual use.

[0008] As a further technical solution of this utility model, an oil storage tank is fixed on the right outer wall of the machine body. An oil scraping assembly is installed inside the oil storage tank. The oil scraping assembly includes a U-shaped scraper frame inside the oil storage tank, with a block fixed to the inner side wall of the U-shaped scraper frame. An electric push rod is fixedly installed on the top surface of the oil storage tank. The output end of the electric push rod slides into the interior of the oil storage tank and is fixedly connected to the block. An oil outlet pipe is fixedly and continuously connected to the bottom of the right outer wall of the oil storage tank. In use, after the oil in the oil storage tank is drained, the electric push rod is controlled and activated to move the U-shaped scraper frame up and down inside the oil storage tank via the block, thereby facilitating the scraping of oil off the inner wall of the oil storage tank and avoiding resource waste. The oil is then drained from the oil storage tank through a valve on the oil outlet pipe for convenient and unified collection.

[0009] As a further technical solution of this utility model, an observation window 1 is provided on the front outer wall of the body and corresponding to the separation chamber, and an observation window 2 is provided on the front outer wall of the oil tank. Both observation windows 1 and 2 are equipped with oil level gauges. Through the oil level gauges on the observation windows, the storage volume inside the main separation chamber and the oil tank can be known in a timely manner, which facilitates timely adjustment.

[0010] This utility model provides a petrochemical oil-water mixture sampling and separation device, which has the following advantages compared with the prior art: 1. This design discloses a petrochemical oil-water mixture sampling and separation device. A drive motor serves as the power source, and with the assistance of a round rod, bevel gear one, bevel gear two, and a hollow rotating rod, it drives a hollow connecting plate to move a scraper in a circular motion on a filter screen. This removes impurities from the outer surface of the filter screen, preventing clogging and facilitating cleaning. Simultaneously, the water guide pipe and nozzle work together to flush the filter screen, further preventing clogging and improving the device's practicality in actual use.

[0011] 2. The petrochemical oil-water mixture sampling and separation device designed in this paper can scrape the oil off the inner wall of the oil storage tank by means of an electric push rod, a square block, and a spiral scraper, thereby avoiding resource waste and increasing the flexibility of the device.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution for a petrochemical oil-water mixture sampling and separation device: it includes a body 1, and four support legs 5 are fixedly installed at the four corners of the outer bottom surface of the body 1. The outer bottom surface of the support legs 5 is provided with through screw holes 501. By turning the bolts in the screw holes 501, the body 1 can be fixed at the designated installation position through the support legs 5, ensuring that the body 1 can operate stably in the later stage, while facilitating disassembly and relocation.

[0016] The machine body 1 has a filter chamber 101 and a separation chamber 102 inside, and the filter chamber 101 and the separation chamber 102 are interconnected. The filter chamber 101 is equipped with a filter screen 103. The top surface of the machine body 1 is fixed with a feed pipe 105 that is interconnected with the filter chamber 101. The oil-water mixture is transported to the filter chamber 101 through the feed pipe 105. Then, the filter screen 103 filters and intercepts the larger solid impurities contained in the oil-water mixture, thereby improving the working effect of subsequent oil-water separation. At the same time, a mounting cover is threaded on the bottom of the machine body 1 and corresponding to the filter chamber 101. A vertical rod is fixed on the top surface of the mounting cover. One end of the vertical rod is connected to the filter screen 103. The mounting cover can be removed by rotating it so that the filter screen 103 can be pulled out for filtration and cleaning through the vertical rod. (This method of use has been disclosed in the cited patent publication CN216837378U, which is an oil-water separation device for processing oil-water mixture. It will not be elaborated in detail in the specification of this application document.)

[0017] A cleaning assembly 2 is provided above the filter screen 103. The cleaning assembly 2 includes a hollow connecting plate 201 located above the filter screen 103. Scrapers 202 are fixed on the outer walls of both the front and rear sides of the hollow connecting plate 201. A hollow rotating rod 203 is fixed and connected through the outer top surface of the hollow connecting plate 201. A square sleeve 204 is fixed on the outer top surface of the body 1. A rotary joint 205 is fixed on the inner top surface of the square sleeve 204. One end of the hollow rotating rod 203 extends rotatably into the interior of the square sleeve 204 and is connected through the rotary joint 205. A round rod 206 is rotatably installed on the inner side wall of the square sleeve 204. A bevel gear 207 is fixed on the outer peripheral side wall of the round rod 206. The outer peripheral side wall of the hollow rotating rod 203 is fixed... The device includes a second bevel gear 208, a first bevel gear 207, and a second bevel gear 208 that mesh with each other. Several nozzles 209 are symmetrically connected to the bottom surface of a hollow connecting plate 201. A vertical plate 210 is fixed to the left end of the top surface of the hollow connecting plate 201. A drive motor 211 is fixedly mounted on the top surface of the body 1. One end of a round rod 206 extends rotatably to the right outer wall of a square sleeve 204 and is fixedly connected to the output end of the drive motor 211. The bottom surfaces of two scrapers 202 abut against the outer surface of the filter screen 103, and the outer walls of the two scrapers 202 that are far apart are inclined. A water guide pipe is fixedly and continuously connected to the top surface of the square sleeve 204, and one end of the water guide pipe is connected to a rotating... The connectors 205 are interconnected. During use, when the filter screen 103 is filtering an oil-water mixture, the drive motor 211 is controlled and activated to drive the round rod 206, which carries the first bevel gear 207, to move in a circular motion inside the square sleeve 204. Under the meshing connection of the first bevel gear 207, the second bevel gear 208 is driven to rotate the hollow rotating rod 203 inside the filter chamber 101. This causes the hollow connecting plate 201 to carry the scraper 202 to move in a circular motion on the outer surface of the filter screen 103, thereby scraping away impurities on the filter screen 103. This prevents impurities trapped by the filter from remaining and accumulating on the filter screen 103 for a long time, which could cause blockage. This also prevents the need for frequent replacement of the filter screen 103 after clogging, thereby improving the filtration efficiency. Furthermore, the vertical plate can scrape off the oil-water mixture adhering to the inner wall of the filter chamber. Before scraping, the water guide pipe is connected to the output pipe of the external water supply equipment. Then, the electric control valve on the water guide pipe is opened to guide the water flow along the rotary joint 205 and the hollow rotating rod 203 into the hollow connecting plate 201. The water is then discharged through several nozzles 209. During the scraping process of the scraper 202, the water flow washes the filter screen 103, thereby further preventing the possibility of clogging and improving the practicality of the device in actual use.

[0018] When the filtered oil-water mixture enters the separation chamber 102, the float plate on the outside of the guide rod slides upward under the action of buoyancy, so that the float plate can be positioned at the upper oily layer of the oil-water mixture under the action of buoyancy, so that the oily layer can be sucked into the oil storage tank 104 by the transfer pump from the oil suction port at the bottom of the float plate for collection. The float plate can be made of PVC or PE material, and the inner wall of the through hole is provided with ball bearings, and multiple sets of ball bearings are provided. By providing ball bearings on the inner wall of the through hole, the friction between the float plate and the guide rod can be reduced when the float plate rises or falls under the action of buoyancy, thereby avoiding jamming. The bottom of the frame is set with There is a secondary filter tank, which is connected to the separation chamber 102 via a delivery pipe. The secondary filter tank is equipped with an oil-water separation membrane. After the oil-water mixture undergoes primary adsorption separation in the separation chamber 102, the valve can be opened to guide it into the secondary filter tank at the bottom of the frame for discharge. The oil-water mixture is then subjected to secondary filtration and separation through the oil-water separation membrane in the secondary filter tank, thereby improving the oil-water separation quality (this method of use has been disclosed in the cited patent publication CN216837378U, which describes an oil-water separation device for treating oil-water mixtures, and will not be elaborated further in this application document).

[0019] An oil reservoir 104 is fixed on the right outer wall of the body 1. An oil scraping assembly 3 is installed inside the oil reservoir 104. The oil scraping assembly 3 includes a spiral scraper frame 301 installed inside the oil reservoir 104. A block 302 is fixed on the inner side wall of the spiral scraper frame 301. An electric push rod 303 is fixedly installed on the outer top surface of the oil reservoir 104. The output end of the electric push rod 303 slides into the interior of the oil reservoir 104 and is fixedly connected to the block 302. An oil outlet pipe 304 is fixedly and continuously connected to the bottom of the right outer wall of the oil reservoir 104. In use, after the oil in the oil storage tank 104 is drained, the electric push rod 303 is controlled and activated to move the circular scraper frame 301 up and down inside the oil storage tank 104 via the block 302, so as to scrape the oil off the inner wall of the oil storage tank 104 and avoid waste of resources. Then the oil in the oil storage tank 104 is drained through the valve on the oil outlet pipe 304 for convenient collection.

[0020] An observation window 4 is provided on the front outer wall of the main body 1, corresponding to the separation chamber 102. An observation window 401 is provided on the front outer wall of the oil tank 104. Both the observation window 4 and the observation window 401 are equipped with oil level gauges 402. Through the oil level gauges 402 on the observation windows, the storage volume inside the main separation chamber 102 and the oil tank 104 can be known in a timely manner, which is convenient for timely adjustment.

[0021] The working principle of this utility model is as follows: When in use, the oil-water mixture is first transported to the filter chamber 101 through the feed pipe 105, and then larger solid impurities contained in the oil-water mixture are filtered and intercepted through the filter screen 103. After that, it flows into the separation chamber 102 for separation processing.

[0022] Simultaneously, the drive motor 211 is started to drive the round rod 206 to carry the bevel gear 207 to move in a circular motion inside the square sleeve 204. Under the meshing connection characteristics of the bevel gear 207, the bevel gear 208 is driven to carry the hollow rotating rod 203 to rotate inside the filter chamber 101, so that the hollow connecting plate 201 carries the scraper 202 to move in a circular motion on the outer surface of the filter screen 103, thereby scraping off the impurities on the filter screen 103.

[0023] At the same time, water is guided through the water pipe along the rotary joint 205 and the hollow rotating rod 203 into the hollow connecting plate 201, and then discharged through several nozzles 209. In the process of scraping by the scraper 202, the water flow washes the filter screen 103, thereby further preventing the possibility of the filter screen 103 becoming clogged.

[0024] After the mixture settles in the separation chamber 102 for a period of time, the oil layer is transported to the inside of the oil storage tank 104 and then discharged through the oil outlet pipe 304. The sediment in the bottom water layer is filtered again through the secondary filter tank and then discharged.

[0025] Finally, after the oil in the oil storage tank 104 is drained, the electric push rod 303 is activated to move the circular scraper frame 301 up and down inside the oil storage tank 104 via the block 302, thereby scraping the oil off the inner wall of the oil storage tank 104 to avoid wasting resources. Then, the scraped oil in the oil storage tank 104 is drained through the valve on the oil outlet pipe 304 for convenient collection.

The control circuit of the controller can be implemented by those skilled in the art through simple programming, and thus can operate normally according to the above steps.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
