Description

Technical Field

[0001] The utility model relates to the field of oil-water separation equipment, in particular to an oil-water separator with a filtering device. Background Art

[0002] The oil-water separator is a device specially designed to effectively separate oil and water. It is widely used in many fields, such as catering, industrial production and shipping, to meet the needs of environmental protection and sewage treatment. Its working principle is mainly to utilize the density difference between water and oil to remove impurities and separate water through gravity sedimentation, thereby achieving complete separation of oil and water.

[0003] Existing oil-water separators mainly use the density difference between water and oil, utilize the principle of gravity sedimentation, and adopt multiple baffles of different heights for filtering. However, in this process, since it relies solely on the effect of gravity, the sedimentation speed of oil droplets and water droplets is relatively slow, resulting in a long separation time and low efficiency. In addition, traditional oil-water separators often lack an effective capture mechanism for tiny oil droplets in the mixed liquid, which allows some oil droplets to escape gravity sedimentation, thereby affecting the final separation effect. Therefore, when traditional oil-water separators are used to treat oily wastewater, it is not only time-consuming, but may also fail to achieve the ideal separation effect. At this time, it is necessary to provide a new oil-water separator with a filtering device to solve this problem. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an oil-water separator with a filtering device to solve the technical problems of the traditional oil-water separator, such as long separation time, low efficiency and poor effect of capturing tiny oil droplets.

[0005] To achieve the above object, the utility model provides the following technical solution: an oil-water separator with a filtering device, comprising a separation mechanism and a sedimentation mechanism, the separation mechanism comprising a treatment box, the interior of the treatment box is respectively provided with a water inlet bin, a first separation bin and a second separation bin;

[0006] The water inlet bin, the first separation bin and the second separation bin are separated by partitions of different heights, and the water inlet bin, the first separation bin and the second separation bin are used for oil-water separation;

[0007] An aeration mechanism is provided at the bottom of the partition at the water inlet bin, and the aeration mechanism includes an aeration seat, one side of the aeration seat is provided with a wedge-shaped surface, the wedge-shaped surface is obliquely arranged toward one side of the water inlet bin, and the wedge-shaped surface is provided with a plurality of aeration ports;

[0008] The aeration mechanism is used to accelerate the separation of oil and water, and the aeration mechanism is used to prevent oil from entering the second separation chamber.

[0009] By adopting the above technical solution, through the combination of the separation mechanism and the sedimentation mechanism, the oil-water mixture can be treated and separated more effectively. The separation mechanism is mainly responsible for the initial oil-water separation, while the sedimentation mechanism further processes the separated water to ensure that the water quality is purer.

[0010] Furthermore, the aeration mechanism is made of stainless steel, and a plurality of aeration ports are provided, and the plurality of aeration ports are equidistantly arranged in a linear array.

[0011] By adopting the above technical solution, the stainless steel material is corrosion-resistant and has high strength, which can ensure the long-term stable operation of the aeration mechanism in harsh environments, extend its service life and reduce maintenance costs.

[0012] Furthermore, a filtering mechanism is provided on the inner wall of the water inlet bin, and the filtering mechanism includes a slide rail, two of which are provided, and a sliding seat is provided inside the two slide rails.

[0013] By adopting the above technical solution, the filtering mechanism effectively intercepts large particles of impurities in the oil-water mixture and protects subsequent processing equipment. The design of the slide rail and the sliding seat makes the installation, disassembly and movement of the filter basket more convenient, thereby improving the maintainability and operating efficiency of the equipment.

[0014] Furthermore, pulleys are arranged on both sides of the sliding seat, and the pulleys are engaged and slidably moved with the slide rails, and a filter basket is installed on the inner side of the sliding seat.

[0015] By adopting the above technical solution, the pulley design reduces the resistance of the sliding seat moving on the slide rail, making the movement of the filter basket smoother and reducing the difficulty of operation. The filter basket, as a core filtering component, can effectively collect and process impurities in the mixture.

[0016] Furthermore, a traction seat is arranged on the top of the sliding seat, and a traction rope is arranged on the top of the traction seat.

[0017] By adopting the above technical solution, the filter basket can be easily lifted by external equipment such as a crane for cleaning or replacement, thereby improving the maintainability and ease of operation of the equipment.

[0018] Furthermore, a traction plate is provided on the top of the traction rope, and the traction plate is mounted on an external crane.

[0019] By adopting the above technical solution and setting a traction plate, a stable mounting point is provided for the external crane, which is convenient for lifting and moving the filter mechanism. This design makes the replacement and cleaning of the filter basket more efficient and safer, reduces the difficulty and risk of manual operation, and improves the maintainability and ease of operation of the equipment.

[0020] Furthermore, the sedimentation mechanism comprises a sedimentation box, a sedimentation pool is provided inside the sedimentation box, and a suction pipe is fixedly connected to the inner axis of the sedimentation pool through a connecting frame.

[0021] By adopting the above technical solution, the design of the sedimentation box and sedimentation tank provides a dedicated space for further processing and sedimentation of separated water to improve water quality. The suction pipe is located at the axis of the sedimentation tank, which can more effectively extract impurities settled at the bottom and keep the sedimentation tank clean and operating efficiently.

[0022] Furthermore, one end of the suction pipe away from the sedimentation box is connected to an external suction pump, and the suction pipe is used to extract the settled impurities.

[0023] By adopting the above technical solution and connecting with an external suction pump, impurities settled at the bottom of the sedimentation tank can be easily extracted to prevent excessive accumulation of impurities that affect the sedimentation effect. This design improves the automation level and processing efficiency of the sedimentation mechanism and reduces the frequency and difficulty of manual cleaning.

[0024] Furthermore, the processing box is connected to the sedimentation box through a water pipe, and a filter is provided at the water inlet of the water pipe, and the filter is used to block larger garbage.

[0025] By adopting the above technical solution, the filter screen is set at the water inlet of the water pipe, which can effectively block larger garbage and impurities from entering the sedimentation tank and protect the sedimentation mechanism from blockage and damage. This design improves the stability and reliability of the entire oil-water separator and extends the service life of the equipment. At the same time, the treatment box and the sedimentation tank are connected by the water pipe to achieve the continuity and efficiency of the process.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model sets an aeration mechanism, wherein the water inlet receives and temporarily stores the oil-water mixture to ensure that it flows evenly into the subsequent separation chamber. The first separation chamber and the second separation chamber use gravity sedimentation and density difference to separate the oil and water in stages to improve purity. By setting an aeration mechanism at the bottom of the partition of the water inlet, when the gas is injected through the aeration port, a large number of tiny bubbles are generated. These bubbles contact the oil-water mixture during the rise, and use their adhesion to carry tiny oil droplets to float, thereby accelerating the separation of the oil droplets and shortening the separation time. In addition, the design of the aeration mechanism ensures that the gas is evenly dispersed in the water inlet, especially its wedge-shaped surface not only increases the contact area between the gas and the mixture, but also improves the oil droplet capture efficiency. More importantly, the bubble barrier formed by aeration can prevent the oil droplets from entering the second separation chamber to a certain extent, so that the oil droplets are more inclined to stay on the upper part of the first separation chamber, ensuring that the water quality of the second separation chamber is relatively pure, solving the problems of long time, low efficiency and poor oil droplet capture of traditional separators;

[0028] 2. The utility model provides a filtering mechanism, in which the engaging and sliding design of the slide rail and the sliding seat makes the installation, disassembly and movement of the filter basket convenient, which is convenient for cleaning and replacement, and improves the flexibility of equipment use and the convenience of maintenance. The pulley reduces the friction during movement, making the movement of the filter basket smoother and more labor-saving, and at the same time plays a supporting and stabilizing role to prevent derailment or tilting. The filter basket, as a core component, effectively intercepts and collects large particles of impurities in the oil-water mixture to achieve preliminary separation of solids and liquids. The connection between the traction seat and the traction rope makes it convenient to lift the filter basket out for cleaning or replacement by an external crane, which improves the convenience and safety of operation. Finally, the traction plate provides a stable mounting point for the crane to ensure the safety and accuracy of the lifting process. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the selection of this material prolongs the service life of the equipment, reduces the frequency of maintenance and replacement, and thus reduces the operating cost. Embodiment 2:

[0038] See also Figure 1 , Figure 2 , Figure 3 A filtering mechanism 3 is provided on the inner wall of the water inlet bin 102. The filtering mechanism 3 includes a slide rail 301. Two slide rails 301 are provided. A sliding seat 302 is provided inside the two slide rails 301. The filter mechanism 3 enables the filter basket to be easily installed, disassembled and moved through the design of the slide rail 301 and the sliding seat 302. This design improves the maintainability and ease of operation of the equipment, and is convenient for regular cleaning and replacement of the filter basket, thereby maintaining the filtering effect.

[0039] See also Figure 1 , Figure 2 , Figure 3 , Figure 4Pulleys 303 are provided on both sides of the sliding seat 302, and the pulleys 303 engage and slide with the slide rails 301.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A traction plate 307 is provided on the top of the traction rope 306, and the traction plate 307 is mounted on the external crane. Through the design of the traction rope 306 and the traction plate 307, the external crane can be conveniently used to lift and lower the filter mechanism. This design not only improves the maintainability of the equipment, but also makes the cleaning and replacement of the filter basket more efficient and safe. At the same time, it also reduces the complexity and risk of manual operation.

[0042] See also Figure 1 , Figure 2 , Figure 3 The sedimentation mechanism 2 includes a sedimentation box 201, a sedimentation tank 202 is opened inside the sedimentation box 201, and a suction pipe 203 is fixedly connected to the internal axis of the sedimentation tank 202 through a connecting frame. The design of the sedimentation mechanism 2 provides a closed environment through the sedimentation box 201, which is conducive to the natural sedimentation of impurities and particulate matter. The sedimentation tank 202 serves as the main sedimentation area. Its design reduces the water flow speed to facilitate the sedimentation of particulate matter. The suction pipe 203 is located at the axis of the sedimentation tank 202, which can more effectively extract impurities settled at the bottom, keep the sedimentation tank 202 clean, and ensure the sedimentation effect.

[0043] See also Figure 1 , Figure 2 , Figure 3 The end of the suction pipe 203 away from the sedimentation tank 201 is connected to an external suction pump. The suction pipe 203 is used to extract the settled impurities. The connection between the suction pipe 203 and the external suction pump makes the extraction of impurities efficient and automatic. This design can continuously and stably remove impurities settled at the bottom of the sedimentation tank 202 to prevent the accumulation of impurities from affecting the sedimentation effect. At the same time, the automated extraction method also reduces the need for manual intervention and improves the operating efficiency and reliability of the equipment.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The treatment box 101 is connected to the sedimentation box 201 through a water pipe 106. A filter screen 105 is arranged at the water inlet of the water pipe 106. The filter screen 105 is used to block larger garbage. The filter screen 105 is arranged at the water inlet of the water pipe 106, which can effectively block large particles of garbage and impurities from entering the sedimentation box 201, thereby protecting the normal operation of the sedimentation mechanism 2. Usually, this design not only extends the service life of the sedimentation mechanism 2, but also ensures the stability of the sedimentation effect. In addition, the treatment box 101 is connected to the sedimentation box 201 through the water pipe 106, thereby realizing the smooth transmission of water flow and the continuity of the treatment process.

[0045] The implementation principle of the utility model is as follows: first, the oil-water mixture needs to enter the water inlet bin 102 of the treatment box 101 through a pipeline. At the entrance of the water inlet bin 102, a filter screen 105 is provided, which can block larger garbage and impurities to ensure that only the oil-water mixture enters the subsequent separation process.

[0046] Then the oil-water mixture will flow through the filter mechanism 3, where the filter basket 304 on the sliding seat 302 will intercept and collect large particles of impurities and solid waste in the oil-water mixture to achieve preliminary solid-liquid separation, and the filtered oil-water mixture will continue to flow into the processing box 101;

[0047] Afterwards, the oil-water mixture will enter the first separation chamber 103 and the second separation chamber 104 for further oil-water separation. In these two chambers, the oil and water will gradually separate by utilizing gravity sedimentation and density difference. In particular, an aeration mechanism 4 is provided on the partition between the water inlet chamber 102 and the first separation chamber 103. The aeration mechanism 4 injects gas into the water inlet chamber 102 through the aeration port 403 to generate a large number of tiny bubbles. These bubbles will carry tiny oil droplets to float during the rising process, thereby accelerating the oil-water separation process. At the same time, the bubble barrier can also prevent oil droplets from entering the second separation chamber 104 to a certain extent, ensuring the relative purity of the water quality in the second separation chamber 104.

[0048] After the oil-water separation is completed, the water will flow into the sedimentation box 201 of the sedimentation mechanism 2 through the water pipe 106. In the sedimentation tank 202, the tiny particles and residual oil droplets in the water will further settle. Finally, through the action of the suction pipe 203 and the external suction pump, the settled impurities will be pumped out of the sedimentation tank 202, thereby obtaining purer water.

[0049] In addition, when the impurities in the filter basket 304 accumulate to a certain extent, the traction plate 307 can be mounted by an external crane, and the sliding seat 302 and the filter basket 304 can be lifted out of the processing box 101 together by using the traction rope 306 and the traction seat 305 for cleaning or replacement. This design greatly improves the maintainability and utilization efficiency of the equipment.
