Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, specifically to a storage device for lubricating fluid. Background Technology

[0002] Lubricating fluid is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. It is mainly used between two relatively moving objects to reduce the friction and wear caused by the contact between the two objects. A lubricating fluid container is a container used to fill lubricating fluid.

[0003] Some lubricants contain solid additives, and lubricants stored in storage tanks are prone to problems such as additive precipitation during storage or long-term standing. Therefore, it is necessary to open the storage tank and stir it manually before use. This stirring process can easily bring external impurities into the originally relatively sealed and safe storage tank environment, causing lubricant contamination, which may affect the normal use of the equipment. In addition, the storage and contamination prevention of the stirrer after manual stirring is also a major problem, which greatly reduces the efficiency of lubricant use and makes the operation cumbersome. Utility Model Content

[0004] In view of this, the present invention provides a lubricant storage device that can automatically and efficiently mix and stir the material in the storage tank through an anti-sedimentation mechanism. This solves the problem that traditional lubricant storage devices require manual stirring after opening the storage tank before use. This stirring process can easily introduce external impurities into the originally relatively sealed and safe storage tank environment, causing lubricant contamination and potentially affecting the normal use of the equipment. Furthermore, the storage and anti-contamination placement of the stirrer after manual stirring is also a major challenge, greatly reducing the efficiency of lubricant retrieval and making operation cumbersome.

[0005] To solve the above-mentioned technical problems, this utility model provides a storage device for lubricating fluid, including a storage tank. The storage tank includes an insulated tank, a heating tank, and a stirring tank arranged sequentially from the outside to the inside. The material is stored in the stirring tank, which is equipped with an anti-sedimentation mechanism. The anti-sedimentation mechanism includes a drive component located at the top of the stirring tank. The output shaft end of the drive component is equipped with a stirring rod that extends into the stirring tank. At least two sets of stirring blades are spaced apart along the axial direction on the outer side of the stirring rod. The lengths of adjacent sets of stirring blades are different, and each stirring blade is provided with a turbulence hole. This utility model can heat the material in the stirring tank through the heating tank, preventing the material from condensing or freezing and settling. The rotation of the stirring blades of different lengths in the anti-sedimentation mechanism in the stirring tank achieves efficient and thorough stirring of the material in the stirring tank. Furthermore, the turbulence hole can turbulently move the material in the stirring tank, preventing sedimentation caused by prolonged stillness. This greatly improves the efficiency of lubricating fluid utilization and the stability of the lubricating fluid product, making operation more convenient and efficient.

[0006] The heating tank is equipped with an electric heater and filled with heat-conducting oil. This invention can achieve stable and efficient heating of the mixing tank by heating the heat-conducting oil with an electric heater, thereby ensuring a suitable temperature inside the mixing tank and preventing materials from freezing and settling, which would affect the usability of the lubricant.

[0007] The side walls of the insulated container are hollow and filled with inert gas, which greatly enhances the heat preservation and cold preservation performance of the storage container, making it easier to ensure the stability of the materials stored in the container.

[0008] The storage tank has a feed inlet at the top, and a sealing cap is provided at the feed inlet. The feed inlet facilitates the quick and convenient addition of materials, and the sealing cap facilitates the effective sealing of the storage tank.

[0009] The storage tank is equipped with a temperature sensor, which facilitates the detection of the temperature inside the storage tank. The controller then controls the rotation of the output shaft of the drive component and the heating operation of the heater, making it more intelligent and efficient.

[0010] The storage tank is equipped with a discharge pipe at the bottom, and a manual switch is installed on the discharge pipe. The manual switch allows for easy opening and closing of the discharge pipe, facilitating the easy discharge of materials.

[0011] A switch valve is also installed at the end of the discharge pipe, which facilitates easy control of the discharge of materials in the discharge pipe.

[0012] The storage tank is also equipped with a sampling tube that penetrates the side wall of the mixing tank. The sampling tube allows for rapid and efficient sampling of the material inside the storage tank, facilitating real-time monitoring of the material inside the storage tank.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Significant anti-sedimentation effect: This utility model can cover the entire depth of the barrel with multiple sets of stirring blades of different lengths, and form a vortex with the turbulence holes, which solves the problem of insufficient stirring and sedimentation of materials in the upper and lower layers in the traditional single stirring blade, and greatly improves the uniformity of lubricant composition.

[0014] 2. Uniform heating and controllable temperature: This utility model can avoid local overheating by indirectly heating with heat transfer oil, and achieve precise temperature control by linking sensors and PLC controller. The temperature fluctuation range inside the barrel is ≤±1℃, which solves the problem of material deterioration caused by uneven heating and temperature runaway in traditional equipment.

[0015] 3. Excellent heat preservation and energy saving performance: This utility model can greatly reduce heat loss by using a hollow insulation structure filled with inert gas such as nitrogen, greatly reduce the start-up and shutdown frequency of heating equipment, significantly reduce energy consumption, and solve the defects of poor heat preservation and high energy consumption of traditional storage tanks.

At least two sets of stirring blades 230 are spaced apart along the axial direction on the outer side of the stirring rod 220. The lengths of adjacent sets of stirring blades 230 are different, and each stirring blade 230 is provided with a turbulence hole 231. Specifically, the insulated tank 110 is made of 304 stainless steel, with a hollow cylindrical structure on the side wall, and the internal filling has a purity of ≥99.9%. The heating tank 120 is made of Q235B carbon steel and is fitted onto the outside of the mixing tank 130, with a 10mm gap between them forming a heating chamber filled with L-QB300 heat transfer oil (manufacturer: Shandong Hengli Petrochemical Co., Ltd.). The tank is equipped with either nitrogen or argon gas. A 300mm inlet mounting base is welded to the top, and a 900mm sampling pipe mounting base and a 600mm discharge pipe mounting base are welded to the lower side wall. An ABS engineering plastic control box is bolted to the outer wall of the tank. Nitrogen or argon, as inert gases, have low thermal conductivity, effectively preventing heat exchange between the tank and the outside environment and improving insulation performance. The heating tank 120 is made of Q235B carbon steel and is fitted onto the outside of the mixing tank 130, with a 10mm gap between them forming a heating chamber. The chamber is filled with L-QB300 heat transfer oil (manufacturer: Shandong Hengli Petrochemical Co., Ltd.). An electric heater 121 (model JRQ-2000, power 2000W, manufacturer: Yancheng Huabang Electric Heating Equipment Co., Ltd.) is bolted to the bottom of the inner side of the heating tank 120. The heater shell is made of 316L stainless steel, which is oil-resistant and corrosion-resistant. The heat transfer oil provides uniform heat transfer, avoiding material deterioration caused by direct heating. The mixing tank 130 is made of 316L stainless steel with a wall thickness of 5mm and a polished inner wall to reduce material adhesion. Its top is connected to the feed inlet 300, its bottom is welded to the discharge pipe 600, and its side wall is welded to the sampling pipe 900. 316L stainless steel contains molybdenum, providing excellent resistance to corrosive media such as lubricants, extending the equipment's service life. The drive component 210 is a stepper motor (model 57HS22, manufacturer: Changzhou Mige Motor Co., Ltd.), fixed to the center of the top of the mixing tank 130 by a 45# steel motor bracket. The motor output shaft passes through a sealed bearing (model 6204-2RS, manufacturer: Harbin Bearing Group Co., Ltd.) at the top of the mixing tank 130, with a graphite packing seal between the shaft and the bearing. The stirring rod 220 is made of 45# steel and is connected to the motor output shaft via a GICL1 type coupling (manufacturer: Botou Changsheng Coupling Co., Ltd.). Three sets of stirring blades 230 are arranged at intervals along the axis of stirring rod 220, with two blades symmetrically distributed in each set, and the blades are made of 316L stainless steel. Each stirring blade 230 has a circular turbulence hole 231, which is evenly distributed along the length direction.The stirring blades 230 of different lengths cover the entire depth of the tank, and the turbulence holes 231 can form local vortices to enhance the stirring effect. This utility model can heat the material in the stirring tank 130 through the heating tank 120, avoiding condensation or freezing and sedimentation of the material. The rotation of the stirring blades 230 of different lengths in the anti-sedimentation mechanism 200 set in the stirring tank 130 achieves efficient and thorough stirring of the material in the stirring tank 130. Furthermore, the turbulence holes 231 can turbulently move the material in the stirring tank 130, preventing sedimentation caused by prolonged stillness. This greatly improves the efficiency of lubricant use and the stability of the lubricant product, making operation more convenient and efficient.

[0021] According to one embodiment of the present invention, such as Figure 1-3 As shown, an electric heater 121 is installed inside the heating tank 120, and the heating tank 120 is filled with heat-conducting oil. This utility model can achieve stable and efficient heating of the mixing tank 130 by heating the heat-conducting oil through the electric heater 121, thereby ensuring that the temperature inside the mixing tank 130 is suitable and avoiding freezing and sedimentation of materials, which would affect the usability of the lubricant.

[0022] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the side wall of the insulated container 110 is hollow and filled with inert gas, which can greatly enhance the heat preservation and cold preservation performance of the storage container 100, and make it easier to ensure the stability of the material inside the storage container 100.

[0023] According to another embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the storage tank 100 has a feed inlet 300 at the top, and a sealing cap 400 is provided at the feed inlet 300. The feed inlet 300 is a funnel-shaped structure made of 304 stainless steel, welded to the top mounting base of the insulated tank 110 and connected to the mixing tank 130. The sealing cap 400 is connected to the feed inlet 300 by threads, and a fluororubber O-ring (model: 150×5, manufacturer: Dongguan Huaqi Sealing Parts Co., Ltd.) is embedded on the inside. The fluororubber has an oil resistance temperature range of -20℃ to 200℃ to ensure reliable sealing. The feed inlet 300 facilitates the quick and convenient addition of materials, and the sealing cap 400 facilitates the effective sealing of the storage tank 100.

[0024] The storage tank 100 is equipped with a temperature sensor 500 and a controller. Specifically, the temperature sensor 500 is a PT100 platinum resistance sensor (model: WZP-230, measurement range -50℃ to 200℃, manufacturer: Shanghai Automation Instrumentation Factory No. 3). The sensing end penetrates the side wall of the heating tank 120 and extends into the heat transfer oil, while the fixed end is connected by a threaded seal. The controller is a PLC controller (model: S7-200 SMART CPU ST20, manufacturer: Siemens (China) Co., Ltd.), located in the control box. The controller's signal input terminal is connected to the temperature sensor 500, and its output terminals are connected to the stepper motor and the electric heater 121, respectively. Temperature thresholds and stirring parameters can be preset. The temperature sensor 500 facilitates the detection of the temperature inside the storage tank 100, and the controller controls the rotation of the output shaft of the drive component 210 and the heating operation of the heater, making it more intelligent and efficient.

[0025] A discharge pipe 600 is installed at the bottom of the storage tank 100, and a manual switch 700 is installed on the discharge pipe 600. Specifically, the discharge pipe 600 is made of 316L stainless steel, and one end is welded to the bottom of the mixing tank 130. It passes through the side walls of the heating tank 120 and the insulation tank 110 in sequence. A manual ball valve (model: Q11F-16, DN25, manufacturer: Zhejiang Yongyi Valve Co., Ltd.) is installed on the pipeline near the tank body. The manual switch 700 facilitates the opening and closing of the discharge pipe 600, which makes it easy to discharge materials. A switching valve 800 is also installed at the end of the discharge pipe 600. Specifically, the switching valve 800 is an electromagnetic switching valve 800 (model: 2W-160-25, voltage: 220V, manufacturer: Shanghai Zheng'an Valve Co., Ltd.) located at the end away from the barrel body. The electromagnetic switching valve 800 is electrically connected to the controller. The dual valve design takes into account both manual emergency and automatic control needs, and the switching valve 800 facilitates the easy discharge of materials in the discharge pipe 600.

[0026] A sampling tube 900, which penetrates the side wall of the mixing tank 130, is also installed on the side wall of the storage tank 100. The sampling tube 900 is made of 316L stainless steel, with one end penetrating through the three layers of the tank body and extending into the mixing tank 130 (to a depth of 1 / 2 of the tank radius). The other end is fitted with a silicone sealing plug (manufacturer as above). The penetration point is sealed with argon arc welding to ensure the airtightness of the tank body. The sampling tube 900 allows for rapid and efficient sampling of the material inside the storage tank 100, facilitating real-time monitoring of the material within the storage tank 100.

[0027] How to use this utility model: First, it should be clarified that the storage device involved in this utility model is mainly used for the storage of various liquid or colloidal fluid materials that have settled or are prone to solidification. This utility model takes the prevention of sedimentation of lubricating fluid during storage as an example to explain its working principle and usage method in detail. The working principle is as follows: This invention achieves heat preservation and heating through a three-layer barrel structure, enhances material mixing with a 200-level anti-sedimentation mechanism, and enables automatic control through an intelligent system. Insulation process: Nitrogen gas in the hollow layer of the insulation tank 110 blocks heat exchange, reduces heat loss inside the tank, and maintains a stable base temperature; Heating process: Electric heater 121 heats the heat transfer oil, which then evenly transfers heat to the side wall of mixing tank 130, achieving indirect heating of the lubricant; Temperature sensor 500 detects the temperature of the heat transfer oil in real time and transmits it to the controller. When the temperature is lower than the preset lower limit (e.g., 25℃), the controller starts the heater, and when the upper limit (e.g., 30℃) is reached, the heater is turned off, achieving constant temperature control. Anti-sedimentation process: The controller starts the stepper motor at a preset frequency (e.g., stirring for 5 minutes every 30 minutes). The motor drives the stirring rod 220 to rotate. The stirring blades 230 of different lengths act on the upper, middle and lower layers of material. The turbulence holes 231 make the material form a vortex, promote radial and axial mixing, and prevent the components from settling. Sealing and material handling: The sealing cap 400 seals the inlet 300 with an O-ring, the sampling tube 900 allows for non-contact sampling, and the discharge tube 600 controls material discharge through a manual valve or solenoid valve, ensuring convenient operation and preventing material contamination. The usage method is as follows: Material addition: Unscrew the sealing cap 400 and inject the lubricant into the mixing tank 130 through the feed inlet 300 (the amount of material injected should not exceed 90% of the tank volume). After injection, tighten the sealing cap 400 to ensure that the O-ring is tightly fitted with the feed inlet 300. Parameter settings: The temperature threshold (e.g., can be set to 25-30℃), stirring frequency (e.g., can be set to stir for 5 minutes every 30 minutes) and stirring speed can be set through the controller operation panel.

[0028] Intelligent operation: When the controller is powered on, the equipment automatically enters the heat preservation, heating and stirring programs. The temperature sensor 500 is linked with the controller to maintain a stable environment inside the tank, and the anti-sedimentation mechanism 200 stirs at regular intervals to prevent sedimentation. Sampling and testing: When materials need to be tested, pull out the 900 sealing plug of the sampling tube, collect the material with the sampling bottle, and put the sealing plug back in after sampling to prevent air from entering. Material discharge: When discharging manually, open the manual ball valve and the material will flow out naturally. Close the valve after discharging. When discharging automatically, the controller sends a command to the solenoid valve 800 to open the discharge valve and close it automatically after the discharge is completed.

[0029] Equipment shutdown: Before long-term shutdown, drain the remaining material in the tank, rinse the mixing tank 130 and pipeline with cleaning solvent, dry them, seal the feed inlet 300 and sampling tube 900, and turn off the controller power.

[0030] This invention enables automatic and efficient mixing of materials in the storage tank 100 via the anti-sedimentation mechanism 200. It solves the problem that traditional lubricant storage requires manual stirring after opening the storage tank before use. This stirring process can easily introduce external impurities into the originally relatively sealed and safe storage tank environment, causing lubricant contamination and potentially affecting the normal use of the equipment. Furthermore, the storage and anti-contamination placement of the stirrer after manual stirring is also a major challenge, greatly reducing the efficiency of lubricant retrieval and making operation cumbersome.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
