Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, and in particular to an oil-water separation device that facilitates the replacement of the oil-water separation membrane. Background Technology

[0002] Oil-water separation membranes are functional filter materials with special surface properties that achieve efficient separation of oil and water through physical or chemical processes. Their core principle is to utilize the distinctly different affinities of the membrane surface for oil and water (i.e., "hydrophilic-oleophobic" or "oleophilic-hydrophobic"), combined with a precise microporous structure, to selectively intercept or allow specific components to pass through.

[0003] In the prior art, such as Chinese Patent No. CN216785851U, an oil-water separation device that facilitates the replacement of the oil-water separation membrane is disclosed. The device includes a separation tank and a tank cover. The tank cover is detachably connected to the upper end of the separation tank. A fixing seat is fixedly connected to the inner wall of the separation tank. A limiting hole is formed on the upper end face of the fixing seat. A sealing gasket is fixedly connected to the upper end face of the fixing seat. An oil-water separation membrane is disposed on the upper end face of the sealing gasket. A limiting post is fixedly connected to the lower end face of the oil-water separation membrane. The limiting post is inserted into the limiting hole. A filter mechanism is fixedly connected to one side of the separation tank through a flow pipe. This oil-water separation device, which facilitates the replacement of the oil-water separation membrane, greatly facilitates the replacement of the membrane when its performance deteriorates, thereby improving the practicality of the oil-water separation device.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although it can separate the oil-water separator membrane from the fixed seat by pulling out the limiting post from the limiting hole, and the limiting post at the lower end of the oil-water separator membrane can be inserted into the limiting hole during installation, thus improving the practicality of the oil-water separator device, the replacement of the oil-water separator membrane requires the operator to use tools or reach into the separator tank by hand to remove the oil-water separator membrane from the separator tank. This process is time-consuming and labor-intensive, resulting in low efficiency in replacing the oil-water separator membrane. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although the oil-water separator membrane can be separated from the fixed base by pulling out the limiting post from the limiting hole, and the limiting post at the lower end of the oil-water separator membrane can be inserted into the limiting hole during installation, thus improving the practicality of the oil-water separator device, the replacement of the oil-water separator membrane requires the operator to use tools or reach into the separator tank by hand to remove the oil-water separator membrane. This process is time-consuming and labor-intensive, resulting in low efficiency in replacing the oil-water separator membrane.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an oil-water separation device that facilitates the replacement of the oil-water separation membrane, comprising: a separation tank, and further comprising:

[0007] Two slids are symmetrically formed on the inner wall of the separator. A slider is slidably connected inside the slids. A movable ring is fixedly connected to one side of the two sliders. An oil-water separation membrane body is set above the movable ring. A pull rope is fixedly connected to the top of the slider. Multiple fixing strips are symmetrically fixedly connected in pairs to the outer surface of the separator. A rotating rod is rotatably connected to one side of the two fixing strips. A winding roller is fixedly connected to the outer surface of the rotating rod. One end of the pull rope is fixedly wound around the outer surface of the winding roller. A bevel gear is fixedly connected to one end of the rotating rod. A fixing plate is symmetrically fixedly connected to the outer surface of the separator. A dual-shaft motor is fixedly connected to the top of the fixing plate. A rotating rod is fixedly connected to both ends of the dual-shaft motor. A bevel gear is fixedly connected to one end of the rotating rod. The bevel gear meshes with the bevel gear.

[0008] Preferably, the outer surface of the movable ring is slidably connected to the inside of the separation tank, two insertion holes are symmetrically opened on the top of the movable ring, the outer surface of the oil-water separation membrane body is slidably connected to the inside of the separation tank, and two insertion rods are symmetrically fixedly connected to the bottom of the oil-water separation membrane body, with the outer surface of the insertion rods inserted into the inside of the insertion holes.

[0009] Preferably, the outer surface of the separation tank is symmetrically fixedly connected to two fixing strips, and the rotating rod is rotatably connected to the fixing strips.

[0010] Preferably, the outer surface of the separation tank is symmetrically fixed with multiple fixing bars three in pairs, and the opposite sides of two fixing bars three are rotatably connected to guide rollers. The pull rope is slidably connected to the guide rollers. Two circular holes are symmetrically opened on the outer surface of the separation tank near the top, and the outer surface of the pull rope is slidably connected to the inside of the circular holes.

[0011] Preferably, the outer surface of the separator near the bottom is fixedly connected with multiple diversion pipes in a circumferential array. Multiple air outlets are equidistantly opened on the outer surface of the diversion pipes. One end of each diversion pipe is fixedly connected to an annular pipe. A one-way valve is fixedly connected to the inner wall of the diversion pipe near the annular pipe.

[0012] Preferably, a fixing plate is fixedly connected to the outer surface of the separator, an air pump is fixedly connected to the top of the fixing plate, a connecting pipe is fixedly connected to the air outlet of the air pump, the connecting pipe is fixedly connected to the annular pipe, and the connecting pipe, the annular pipe, the diverter pipe and the air outlet are interconnected.

[0013] Preferably, the top of the separating tank is detachably connected to a tank cover, and the top of the tank cover is fixedly connected to a liquid inlet pipe, which is connected to the separating tank.

[0014] Preferably, an oil outlet pipe is fixedly connected to the outer surface of the separator near the top, and a water outlet pipe is fixedly connected to the outer surface of the separator near the bottom. Valves are fixedly connected to the outer surfaces of both the oil outlet pipe and the water outlet pipe.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model controls the dual-axis motor to start via a controller, causing its output shaft to drive the rotating rod and bevel gear one to rotate. Then, with the meshing of bevel gear one and bevel gear two, bevel gear two can drive the rotating rod two to rotate, synchronously driving the winding roller to rotate and winding the pull rope. The pull rope slides along the outer surface of the guide roller and applies an upward pulling force to the slider, causing the slider to slide upward along the inside of the groove. This synchronously drives the movable ring and the oil-water separator membrane body to move upward, at which point the oil-water separator membrane body can be removed. This allows workers to easily remove the oil-water separator membrane body from the separation tank. This process is time-saving and labor-saving, thereby improving the efficiency of replacing the oil-water separator membrane body.

[0017] 2. This utility model controls the air pump to start via a controller, which delivers gas into the annular pipe through a connecting pipe, increasing the gas pressure in the annular pipe. Since the one-way valve opens from the annular pipe toward the inside of the separator, the one-way valve opens, allowing gas to enter the water through the diverter and outlet, generating numerous tiny bubbles. These bubbles rise and contact the oil-water separation membrane, allowing them to pass through the pores of the membrane, clearing blockages and preventing clogging that could affect the oil-water separation efficiency. The gas then enters the upper oil-water mixture, causing the oil and water mixture to flow and mix. This not only improves the efficiency of oil-water separation but also reduces the frequency of replacing the oil-water separation membrane. Attached Figure Description

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Examples, such as Figure 1-4As shown, this utility model provides an oil-water separation device that facilitates the replacement of the oil-water separation membrane, including: a separation tank 1, and two sliding grooves 111 symmetrically formed on the inner wall of the separation tank 1. A slider 110 is slidably connected inside the sliding grooves 111. A movable ring 106 is fixedly connected to the opposite side of the two sliders 110. An oil-water separation membrane body 107 is disposed above the movable ring 106. A pull rope 209 is fixedly connected to the top of the sliders 110. Multiple fixing strips 205 are symmetrically fixedly connected in pairs to the outer surface of the separation tank 1. A rotating rod 206 is rotatably connected to one side. A take-up roller 208 is fixedly connected to the outer surface of the rotating rod 206. One end of the pull rope 209 is fixedly wound and connected to the outer surface of the take-up roller 208. A gear 2 is fixedly connected to one end of the rotating rod 206. A fixing plate 2 is symmetrically fixedly connected to the outer surface of the separation tank 1. A dual-shaft motor 201 is fixedly connected to the top of the fixing plate 2. A rotating rod 202 is fixedly connected to both ends of the dual-shaft motor 201. A bevel gear 203 is fixedly connected to one end of the rotating rod 202. The bevel gear 203 meshes with the bevel gear 207.

[0027] Furthermore, such as Figure 1-4 As shown, the outer surface of the movable ring 106 is slidably connected to the inside of the separator tank 1. Two insertion holes 108 are symmetrically opened on the top of the movable ring 106. The outer surface of the oil-water separator membrane body 107 is slidably connected to the inside of the separator tank 1. Two insertion rods 109 are symmetrically fixedly connected to the bottom of the oil-water separator membrane body 107. The outer surface of the insertion rods 109 is inserted into the inside of the insertion holes 108. With the above arrangement, the insertion rods 109 can be inserted into the insertion holes 108 to complete the installation of the oil-water separator membrane body 107. Conversely, the oil-water separator membrane body 107 can be quickly removed from the top of the movable ring 106.

[0028] Furthermore, such as Figure 1-4 As shown, two fixing strips 204 are symmetrically fixed to the outer surface of the separation tank 1. The rotating rod 202 is rotatably connected to the fixing strips 204. The fixing strips 204 provide a certain support for the rotating rod 202, thereby improving the stability of the rotation of the rotating rod 202.

[0029] Furthermore, such as Figure 1-4 As shown, multiple fixing bars 210 are symmetrically fixed to each other on the outer surface of the separation tank 1. Guide rollers 211 are rotatably connected to the opposite side of two fixing bars 210. The pull rope 209 is slidably connected to the guide rollers 211. Two circular holes 103 are symmetrically opened on the outer surface of the separation tank 1 near the top. The outer surface of the pull rope 209 is slidably connected to the inside of the circular holes 103. The guide rollers 211 play a certain guiding role for the pull rope 209. The circular holes 103 allow the pull rope 209 to slide inside the circular holes 103.

[0030] Furthermore, such as Figure 1-4 As shown, multiple diversion pipes 304 are fixedly connected in a circumferential array on the outer surface of the separator 1 near the bottom. Multiple air outlets are equidistantly opened on the outer surface of the diversion pipes 304. One end of each diversion pipe 304 is fixedly connected to an annular pipe 303. A one-way valve is fixedly connected to the inner wall of the diversion pipe 304 near the annular pipe 303. With the above arrangement, when the air pressure inside the annular pipe 303 increases, the one-way valve can be opened, allowing gas to enter the diversion pipe 304 and generate bubbles through the air outlets.

[0031] Furthermore, such as Figure 1-4 As shown, a fixing plate 3 is fixedly connected to the outer surface of the separator 1. An air pump 301 is fixedly connected to the top of the fixing plate. A connecting pipe 302 is fixedly connected to the air outlet of the air pump 301. The connecting pipe 302 is fixedly connected to the annular pipe 303. The connecting pipe 302, the annular pipe 303, the diversion pipe 304 and the air outlet are connected. The controller controls the air pump 301 to start, so that it delivers gas to the annular pipe 303 through the connecting pipe 302. The gas enters the water through the diversion pipe 304 and the air outlet, generating a large number of tiny bubbles. The bubbles rise and come into contact with the oil-water separation membrane body 107, allowing the bubbles to pass through the pores of the oil-water separation membrane, clearing the pores and preventing blockage that would affect the efficiency of oil-water separation. The bubbles then enter the upper oil-water mixture, causing the oil-water mixture to flow and mix with each other.

[0032] Furthermore, such as Figure 1-4 As shown, a tank cover 101 is detachably connected to the top of the separator 1. An inlet pipe 102 is fixedly connected to the top of the tank cover 101. The inlet pipe 102 is connected to the separator 1, and an oil-water mixture is added to the interior of the separator 1 through the inlet pipe 102.

[0033] Furthermore, such as Figure 1-4 As shown, an oil outlet pipe 104 is fixedly connected to the outer surface of the separator 1 near the top, and a water outlet pipe 105 is fixedly connected to the outer surface of the separator 1 near the bottom. Valves are fixedly connected to the outer surfaces of both the oil outlet pipe 104 and the water outlet pipe 105. By opening the valves of the oil outlet pipe 104 and the water outlet pipe 105, oil and water can be discharged through the oil outlet pipe 104 and the water outlet pipe 105 respectively.

[0034] Working principle: During use, an oil-water mixture is added to the separator 1 through the inlet pipe 102. Under the action of the oil-water separation membrane body 107, water permeates through the membrane into the lower part of the separator 1, while the oil remains at the top. By opening the valves of the oil outlet pipe 104 and the water outlet pipe 105, the oil and water can be discharged respectively through these pipes. After the oil-water separation membrane body 107 has filtered the oil-water mixture for a period of time, the valve of the water outlet pipe 105 is closed, causing the water level to rise to the bottom of the oil-water separation membrane. Upon contact, the controller activates the air pump 301, which delivers gas through the connecting pipe 302 into the annular pipe 303, increasing the gas pressure within the annular pipe 303. Since the one-way valve opens from the annular pipe 303 towards the interior of the separator tank 1, it allows gas to enter the water through the diverter pipe 304 and the outlet, generating numerous tiny bubbles. These bubbles rise and contact the oil-water separation membrane body 107, clearing the pores and preventing blockages that could affect the efficiency of oil-water separation. The oil enters the upper oil-water mixture, allowing the oil and water to flow and mix, thus improving the efficiency of oil-water separation and reducing the frequency of oil-water separator body 107 replacement. When the oil-water separator body 107 needs to be replaced, the tank cover 101 is opened, and the dual-shaft motor 201 is started by controlling the controller. Its output shaft drives the rotating rod 202 and bevel gear 203 to rotate. Then, with the meshing of bevel gear 203 and bevel gear 207, bevel gear 207 drives the rotating rod 206 to rotate. The movement synchronously drives the take-up roller 208 to rotate, winding the pull rope 209 so that the pull rope 209 slides along the outer surface of the guide roller 211 and applies an upward pulling force to the slider 110, causing the slider 110 to slide upward along the inside of the slide groove 111. This synchronously drives the movable ring 106 and the oil-water separation membrane body 107 to move upward, at which point the oil-water separation membrane body 107 can be removed. This allows the workers to easily remove the oil-water separation membrane body 107 from the separation tank 1, which is time-saving and labor-saving, thereby improving the efficiency of replacing the oil-water separation membrane body 107.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
