Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to an oil-water separation device for wastewater from rubber granule production. Background Technology

[0002] Rubber is a widely used material. Its elasticity allows it to stretch and recover under pressure, making it widely used in tires, sporting goods, and various seals. Rubber is used to manufacture various industrial products, such as automobile tires, rubber shoes, sealing rings, and tapes. It is also widely used in consumer goods, such as sporting goods and toys. During the mixing and processing of rubber products, water cooling systems or water may be used to rinse the rubber mixture. The rinsing wastewater contains high concentrations of organic matter, suspended solids, heavy metal ions, as well as pollutants such as oils and sulfides. If it is discharged directly without proper treatment, it will cause serious environmental pollution.

[0003] Existing oil-water separation devices for rubber granule production wastewater typically separate oil and emulsified oil by adding coagulants and flocculants to the wastewater, causing the floating oil and emulsified oil to float on the surface. The separation is achieved by cleaning the floating oil and emulsified oil from the top of the wastewater. However, during operation, the coagulants and flocculants often react unevenly with the wastewater, resulting in some floating oil and emulsified oil remaining inside. Furthermore, the efficiency of cleaning the floating oil and emulsified oil from the wastewater surface is low, making it inconvenient for users. Utility Model Content

[0004] This application provides an oil-water separation device for rubber granule production wastewater, to solve the problem that existing oil-water separation devices for rubber granule production wastewater generally separate oil and water by adding coagulants and flocculants to the wastewater to make the oil float on the surface and then cleaning the oil at the top of the wastewater. However, during use, the coagulants and flocculants are prone to uneven reaction with the wastewater, resulting in the presence of oil and floating matter that have not floated to the top inside. At the same time, the cleaning efficiency of oil and floating matter on the surface of the wastewater is low.

[0005] This application provides an oil-water separation device for wastewater from rubber granule production, including a support base, a filter box installed at one end of the support base, a water pump installed at one end of the filter box, an oil-water separation tank installed at one end of the filter box, a separation chamber opened inside the oil-water separation tank, an air pump installed at the top of the support base, an air extraction pipe installed at one end of the air pump, an exhaust pipe installed at the end of the air pump away from the air extraction pipe, a baffle installed on one side of the separation chamber, a drive electric cylinder installed at one end of the oil-water separation tank, an oil scraper installed at one end of the drive electric cylinder, limit sliders installed at both ends of the oil scraper, and an oil storage tank installed on one side of the separation chamber.

[0006] Preferably, the filter box has a water inlet at the top and a filter plate is installed inside the filter box.

[0007] Preferably, one end of the water pump is connected to a drain pipe.

[0008] Preferably, a sealing plate is installed on one side of the inside of the oil-water separator.

[0009] Preferably, the exhaust pipe is connected to an air guide pipe at its top end, and an air jet is installed at the top end of the air guide pipe.

[0010] Preferably, a limiting groove is provided on the inner wall of the top of the separation chamber.

[0011] Preferably, an oil drain pipe is installed at one end of the oil storage tank, and an oil drain valve is installed at the top end of the oil drain pipe.

[0012] Beneficial effects:

[0013] Considering that existing oil-water separation devices for rubber granule production wastewater generally separate oil and water by adding coagulants and flocculants to the wastewater to make the oil float on the surface and then cleaning the oil from the top of the wastewater, the problem is that the coagulants and flocculants react unevenly with the wastewater during use, resulting in the presence of oil and floating matter that have not floated to the top. At the same time, cleaning the oil and floating matter on the surface of the wastewater is inefficient.

[0014] Wastewater from rubber granulation production is poured into a filter box through an inlet. The filter plates inside the box filter particulate matter, preventing blockages in subsequent pipes. A water pump is then activated, drawing the filtered wastewater through a drain pipe. From there, the wastewater is introduced into a separation chamber. Coagulants and flocculants are added to the separation chamber, and then an air pump is activated, releasing air bubbles from the bottom of the chamber. These bubbles lift suspended solids and oil to the surface. It is important to note that the wastewater level inside the separation chamber should be controlled. Without exceeding the height of the baffle, once the suspended solids and oil in the wastewater float to the surface, the water pump is continuously turned on to inject wastewater into the separation chamber, causing the wastewater level inside the separation chamber to rise until it exceeds the baffle. Since the suspended solids and oil float on the surface, when the wastewater level is higher than the separation chamber, the suspended solids and oil will flow to the oil storage tank immediately. At this time, by turning on the drive cylinder, the oil scraper moves at the top of the separation chamber, thereby pushing the suspended solids and oil at the top of the separation chamber to flow to the oil storage tank, increasing the collection efficiency of suspended solids and oil.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-5 The oil-water separation device for rubber granule production wastewater shown includes a support base 1, a filter box 2 installed at one end of the support base 1, a water pump 5 connected to one end of the filter box 2, an oil-water separation box 8 installed at one end of the filter box 2, a separation chamber 10 opened inside the oil-water separation box 8, an air pump 11 installed at the top of the support base 1, an air extraction pipe 12 installed at one end of the air pump 11, an exhaust pipe 13 installed at the end of the air pump 11 away from the air extraction pipe 12, a baffle 16 installed on one side of the separation chamber 10, a drive cylinder 17 installed at one end of the oil-water separation box 8, an oil scraper 18 connected to one end of the drive cylinder 17, limit sliders 19 installed at both ends of the oil scraper 18, and an oil storage tank 21 provided on one side of the separation chamber 10.

[0031] In this process, wastewater from rubber granulation is poured into filter box 2 through inlet 3. The filter plate 4 inside filter box 2 filters particulate matter from the wastewater, preventing blockage of subsequent pipes. Then, pump 5 is turned on, causing pumping pipe 6 to draw the filtered wastewater into drain pipe 7, which then guides the wastewater into separation chamber 10. Coagulant and flocculant are added to separation chamber 10, and then air pump 11 is turned on, causing jet nozzle 15 to release air bubbles to the bottom of separation chamber 10. These air bubbles float suspended solids and oil to the surface. It is important to note that the wastewater level inside separation chamber 10 should be controlled. Without exceeding the height of the baffle 16, when suspended solids and oil in the wastewater float to the surface, the water pump 5 is turned on to inject wastewater into the separation chamber 10, thereby raising the wastewater level inside the separation chamber 10 until it exceeds the baffle 16. Since suspended solids and oil float on the surface, when the wastewater level is higher than the separation chamber 10, the suspended solids and oil will flow to the oil storage tank 21 immediately. At this time, the drive cylinder 17 is turned on to move the oil scraper 18 at the top of the separation chamber 10, thereby pushing the suspended solids and oil at the top of the separation chamber 10 to flow to the oil storage tank 21, increasing the collection efficiency of suspended solids and oil.

[0032] The top of the filter box 2 is provided with a water inlet 3, and a filter plate 4 is installed inside the filter box 2.

[0033] In this process, the wastewater from the production of rubber granules is poured into the filter box 2 through the inlet 3. The particulate matter in the wastewater is filtered by the filter plate 4 inside the filter box 2 to avoid clogging of subsequent pipelines.

[0034] One end of the water pump 5 is connected to a drain pipe 7.

[0035] Specifically, by turning on the water pump 5, the water pumping pipe 6 draws the filtered wastewater into the drain pipe 7, and then the drain pipe 7 guides the wastewater into the interior of the separation chamber 10.

[0036] A sealing plate 9 is installed on one side of the inside of the oil-water separator 8.

[0037] In this process, a sealing plate 9 is installed inside the oil-water separator 8 to prevent the water pump 5 from coming into contact with the wastewater inside the separator 10. At the same time, the height of the baffle 16 is lower than the height of the sealing plate 9.

[0038] The exhaust pipe 13 is connected to the top of the air guide pipe 14, and the air guide pipe 14 is equipped with the jet head 15.

[0039] In this process, by turning on the air pump 11, the jet head 15 releases air bubbles to the bottom of the separation chamber 10, which in turn float suspended solids and oil to the surface.

[0040] A limiting groove 20 is provided on the inner wall of the top of the separation chamber 10.

[0041] When the scraper blade 18 moves, it slides along the limiting grooves 20 at both ends, and the movement of the scraper blade 18 is limited by the limiting grooves 20.

[0042] An oil drain pipe 22 is installed at one end of the oil storage tank 21, and an oil drain valve 23 is installed at the top of the oil drain pipe 22.

[0043] When it is necessary to discharge suspended solids and oil inside the oil storage tank 21, the oil discharge valve 23 can be opened, and the oil discharge pipe 22 can be used to discharge the suspended solids and oil inside the oil storage tank 21.

[0044] Working principle: When using this oil-water separation device for rubber granule production wastewater, the wastewater from rubber granule production is poured into the filter box 2 through the inlet 3. The filter plate 4 inside the filter box 2 filters the particulate matter in the wastewater to prevent blockage of subsequent pipes. Then, the water pump 5 is turned on, and the water pump 6 draws the filtered wastewater into the drain pipe 7. The wastewater is then introduced into the separation chamber 10 through the drain pipe 7. Coagulant and flocculant are added into the separation chamber 10. Then, the air pump 11 is turned on, and the air jet 15 releases air bubbles to the bottom of the separation chamber 10. The air bubbles float suspended solids and oil to the surface. It should be noted that the height of the wastewater inside the separation chamber 10 does not exceed the height of the baffle 16.

[0045] When suspended solids and oil in the wastewater float to the surface, the water pump 5 is turned on again to inject wastewater into the separation chamber 10, thereby raising the wastewater level inside the separation chamber 10 until it exceeds the baffle 16. Since suspended solids and oil float on the surface, when the wastewater level is higher than the separation chamber 10, the suspended solids and oil will flow to the oil storage tank 21 immediately. At this time, the drive cylinder 17 is turned on to move the oil scraper 18 at the top of the separation chamber 10, thereby pushing the suspended solids and oil at the top of the separation chamber 10 to flow to the oil storage tank 21, increasing the collection efficiency of suspended solids and oil.

[0046] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
