Description

Technical Field

[0001] This utility model relates to an online micro-water removal device for hydraulic oil, belonging to the field of hydraulic oil processing technology. Background Technology

[0002] Dewatering devices are equipment or systems used in the field of mechanical engineering to remove moisture from materials. They are widely used in engineering fields such as concrete vacuum treatment and river dredging. In concrete engineering, this device removes moisture by controlling the degree of vacuum, which directly affects the performance of concrete. In river management, dewatering devices can quickly separate silt and impurities, treat organic pollutants, and achieve sediment classification and residual water purification. In addition, dewatering devices also have important applications in fields such as mineral processing. When hydraulic oil is processed, dewatering devices are needed to remove the moisture inside it.

[0003] Chinese Patent Publication No. CN 214244334 U discloses a deep dehydration device for hydraulic oil, comprising an outer casing, a dehydration tank fixedly connected inside the outer casing, a motor fixedly connected to the top of the outer casing, a rotating shaft fixedly connected to the output shaft of the motor, and the bottom end of the rotating shaft rotatably connected to the bottom inner wall of the dehydration tank. Multiple symmetrically arranged centrifugal plates are welded to the outer circumference of the rotating shaft. A blower and a dryer are fixedly connected to the right side of the outer casing. The output end of the blower and the input end of the dryer are connected through a third connecting pipe. A second connecting pipe is fixedly sleeved on the output end of the dryer, and a first solenoid valve is installed on the second connecting pipe. This invention not only achieves double deep dehydration with high efficiency and good dehydration effect, but also does not affect the inherent properties of the hydraulic oil, thus improving the practicality of the device.

[0004] The aforementioned device mainly relies on centrifugation to separate oil and water. However, in actual use, its effect on separating emulsified water is limited. As a result, it may not be able to remove trace amounts of water from hydraulic oil with low water content. This would prevent the hydraulic oil with low water content from undergoing proper dehydration, which may affect the normal operation of the hydraulic oil in the future.

[0005] To address this, an online micro-water removal device for hydraulic oil is proposed. Summary of the Invention

[0006] In view of this, the present invention provides an online micro-water removal device for hydraulic oil to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is achieved as follows: an online micro-water removal device for hydraulic oil, comprising:

[0008] A support assembly includes a tank body, a cover plate threadedly connected to the top of the tank body, an mounting bracket fixedly installed on the surface of the cover plate, a one-way oil drain valve fixedly installed at the bottom of the tank body, and a base plate fixedly installed at the bottom of the tank body.

[0009] A dehydration assembly includes an oil inlet pipe fixedly installed in the inner cavity of a tank. The right side of the oil inlet pipe penetrates the inner surface of the tank and extends to the outer side of the tank. A spray head is connected to the bottom of the oil inlet pipe. A heating chamber is formed on the inner surface of the tank. A heating tube is fixedly installed in the inner cavity of the heating chamber. A vacuum pump is fixedly installed on the top of the cover plate. A connecting pipe is connected to the input end of the vacuum pump. The end of the connecting pipe away from the vacuum pump is connected to the inner cavity of the tank. A frame is provided in the inner cavity of the tank. A molecular sieve plate is fixedly installed on the inner side of the frame.

[0010] More preferably, the surface of the frame is threaded with fixing bolts, and the bottom of the fixing bolts is threaded to the inner surface of the tank.

[0011] More preferably, a temperature sensor is fixedly installed on the left side of the top of the cover plate, and the detection end of the temperature sensor extends into the inner cavity of the tank.

[0012] More preferably, a pressure sensor is fixedly installed at the middle of the top of the cover plate, and the detection end of the pressure sensor extends into the inner cavity of the tank.

[0013] More preferably, a water vapor sensor is fixedly installed on the right side of the top of the cover plate, and the detection end of the water vapor sensor extends into the inner cavity of the tank.

[0014] More preferably, the inner cavity of the heating chamber is filled with a thermally conductive material, which is thermally conductive silicone grease.

[0015] More preferably, a heat insulation board is fixedly installed on the outer surface of the tank, and the heat insulation board is made of rock wool board.

[0016] More preferably, the bottom plate is threaded with anchor bolts on all four sides, and the bottom of the anchor bolts is threaded to the inner surface of the tank.

[0017] The present invention has the following advantages due to the adoption of the above technical solution:

[0018] I. This utility model, by setting up a dehydration component, first heats the inner cavity of the tank through a heating pipe, while a vacuum pump converts the inner cavity of the tank into a negative pressure state. Then, the oil is dispersed into fine droplets through a spray head, thereby increasing the contact area between the oil and the low-pressure thermal environment in the inner cavity of the tank. At this time, under negative pressure, the boiling point of water in the hydraulic oil decreases, and water vapor is passed through the surface of the molecular sieve plate by the re-run of the vacuum pump. The molecular sieve plate adsorbs the water in the water vapor, thereby achieving the dehydration of hydraulic oil with low water content. Compared with simply using centrifugation to separate oil and water, this method can ensure the dehydration effect and efficiency of hydraulic oil, and is convenient for operators to use.

[0019] II. This utility model, by incorporating fixing bolts, facilitates the disassembly and assembly of the molecular sieve plate, enabling periodic regeneration. The temperature sensor monitors the temperature within the tank cavity, allowing for adjustment of the heating element's heating amplitude. The pressure sensor detects the pressure within the tank cavity, preventing excessive or insufficient pressure that could affect the dehydration of the hydraulic oil. The steam sensor detects the separated steam within the tank cavity, facilitating timely discharge of the dehydrated hydraulic oil after steam dissipates. The use of heat-conducting material improves the uniformity of heating the tank, effectively preventing localized overheating. The heat insulation plate prevents heat from the heating element from being conducted to the outside of the tank, avoiding accidental burns to operators. The anchor bolts provide overall stability, preventing shaking due to accidental collisions.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0031] like Figure 1-5 As shown, this utility model embodiment provides an online micro-water removal device for hydraulic oil, comprising:

[0032] Support assembly 1 includes a tank body 101, a cover plate 102 is threadedly connected to the top of the tank body 101, an mounting bracket 103 is fixedly installed on the surface of the cover plate 102, a one-way oil drain valve 104 is fixedly installed at the bottom of the tank body 101, and a bottom plate 105 is fixedly installed at the bottom of the tank body 101.

[0033] The dehydration component 2 includes an oil inlet pipe 201, which is fixedly installed in the inner cavity of the tank 101. The right side of the oil inlet pipe 201 penetrates the inner surface of the tank 101 and extends to the outer side of the tank 101. The bottom of the oil inlet pipe 201 is connected to a spray head 202. A heating chamber 203 is opened on the inner surface of the tank 101. A heating pipe 204 is fixedly installed in the inner cavity of the heating chamber 203. A vacuum pump 205 is fixedly installed on the top of the cover plate 102. A connecting pipe 206 is connected to the input end of the vacuum pump 205. The end of the connecting pipe 206 away from the vacuum pump 205 is connected to the inner cavity of the tank 101. A frame 207 is provided in the inner cavity of the tank 101. A molecular sieve plate 208 is fixedly installed on the inner side of the frame 207.

[0034] By setting up the dehydration component 2, the inner cavity of the tank 101 is first heated by the heating pipe 204, and the vacuum pump 205 converts the inner cavity of the tank 101 into a negative pressure state. Then, the oil is dispersed into fine droplets by the spray head 202, thereby increasing the contact area between the oil and the low-pressure thermal environment in the inner cavity of the tank 101. At this time, under the negative pressure, the boiling point of water in the hydraulic oil decreases, and water vapor is passed through the surface of the molecular sieve plate 208 by the re-run of the vacuum pump 205. The molecular sieve plate 208 adsorbs the water in the water vapor, thereby achieving the dehydration of hydraulic oil with low water content. Compared with simply using centrifugation to separate oil and water, this method can ensure the dehydration effect and efficiency of hydraulic oil, and is convenient for operators to use. Example 2

[0035] like Figure 1-6 As shown, in one embodiment, the surface of the frame 207 is threaded with fixing bolts 209, the bottom of the fixing bolts 209 being threaded to the inner surface of the tank 101. A temperature sensor 210 is fixedly installed on the left side of the top of the cover plate 102, with the detection end of the temperature sensor 210 extending into the inner cavity of the tank 101. A pressure sensor 211 is fixedly installed at the middle of the top of the cover plate 102, with the detection end of the pressure sensor 211 extending into the inner cavity of the tank 101. A water vapor sensor 212 is fixedly installed on the right side of the tank 101. The detection end of the water vapor sensor 212 extends into the inner cavity of the tank 101. The inner cavity of the heating chamber 203 is filled with a thermally conductive material 213, which is made of thermally conductive silicone grease. A heat insulation plate 214 is fixedly installed on the outer surface of the tank 101. The heat insulation plate 214 is made of rock wool board. Anchor bolts 106 are threaded around the top of the bottom plate 105. The bottom of the anchor bolts 106 is threaded to the inner surface of the tank 101.

[0036] By setting the fixing bolts 209, the molecular sieve plate 208 can be easily disassembled and assembled, facilitating periodic regeneration of the molecular sieve plate 208. The temperature sensor 210 allows monitoring of the temperature inside the tank 101, facilitating adjustment of the heating amplitude of the heating tube 204. The pressure sensor 211 detects the pressure inside the tank 101, preventing excessive or insufficient pressure from affecting the dehydration of the hydraulic oil. The water vapor sensor 212 monitors the separated water vapor inside the tank 101. The system allows for timely discharge of dehydrated hydraulic oil after the water vapor dissipates. The heat-conducting material 213 improves the heating uniformity of the heating tube 204 on the tank 101, effectively preventing localized high temperatures in the tank 101. The heat insulation plate 214 prevents the heat from the heating tube 204 from being conducted to the outside of the tank 101, thus preventing burns to operators from accidental contact. The anchor bolts 106 stabilize the equipment and prevent shaking due to accidental collisions.

[0037] In operation, this invention works as follows: First, the output of the vacuum pump 205 is conducted through the connecting pipe 206 to create a negative pressure state in the tank 101. Then, the output of the heating pipe 204 initiates heating. The heat from the heating pipe 204 is evenly conducted to the inner cavity of the tank 101 through the heat-conducting material 213, raising the temperature inside the tank 101. Subsequently, oil is injected into the tank 101 through the oil inlet pipe 201, and the oil is dispersed into fine droplets by the spray head 202. The water is evenly sprayed onto the inner wall of the tank 101. Under negative pressure, the boiling point of water in the hydraulic oil decreases, and the water is converted into water vapor and separated from the hydraulic oil. When the water vapor sensor 212 detects the water vapor, the vacuum pump 205 runs again, causing the water vapor to be drawn upward. The water vapor then passes through the molecular sieve plate 208, which adsorbs the water vapor, thereby removing the water from the hydraulic oil. The hydraulic oil with the water removed is then discharged through the one-way drain valve 104.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
