Description
Technical Field
[0001] This utility model relates to the field of hydraulic oil tank technology, specifically a hydraulic oil tank with a temperature control structure. Background Technology
[0002] A hydraulic oil tank is a container used to store the hydraulic fluid required to ensure the operation of a hydraulic system. Based on whether the oil level in the tank is open to the atmosphere, oil tanks can be divided into two types: open and closed. Open oil tanks are used in general hydraulic systems; closed oil tanks are used underwater and in hydraulic systems with strict requirements for operational stability and noise.
[0003] In existing hydraulic oil tanks, an electric heater is added to the tank to heat the oil. The on / off status of the electric heater is determined by checking the oil temperature.
[0004] However, when using existing hydraulic oil tanks, the oil temperature in the tank becomes too low in winter, the hydraulic oil viscosity increases, the fluidity decreases, and the flow resistance increases, resulting in insufficient oil supply to the equipment. When the oil temperature is below 10°C, it will seriously affect the hydraulic motor, pipeline, and control valve, and blockage failures are likely to occur. It is impossible to adjust the temperature according to the actual situation, which limits its use. In order to address the above problems, a hydraulic oil tank with a temperature control structure is proposed. Utility Model Content

[0032] Combination Figure 1 This utility model discloses a hydraulic oil tank with a temperature control structure, comprising an outer shell 1, a second mesh plate 28 fixedly connected to the top of the inner wall of the outer shell 1, a hydraulic oil tank body 3 disposed on the inner wall of the second mesh plate 28, the second mesh plate 28 being used for ventilation, a temperature sensor 4 penetrating and disposed at the top of the hydraulic oil tank body 3, the temperature sensor 4 detecting the temperature of the oil in the hydraulic oil tank body 3, a base 2 fixedly connected to the bottom of the outer shell 1, and a second conveying copper pipe 18 penetrating and fixedly connected to the other end of the hydraulic oil tank body 3, the second conveying copper pipe 18 and the first conveying copper pipe 11 being spirally wound in the hydraulic oil tank. When the main body 3 is conveying, it accelerates heat dissipation and temperature rise. The other end of the first conveying copper pipe 11 is connected to the hydraulic oil tank body 3. The outer wall of the hydraulic oil tank body 3 is provided with the first conveying copper pipe 11 and the second conveying copper pipe 18 spirally wound. Both the first conveying copper pipe 11 and the second conveying copper pipe 18 are made of copper, which has good heat conduction. The top of the inner wall of the base 2 is provided with the first mesh plate 22. Two guide rails 15 are fixedly connected to the right side of the outer wall of the outer shell 1. The baffle 14 can be removed by moving the baffle 14 upward to carry out heat dissipation. The baffle 14 is slidably connected between the two guide rails 15.
[0033] Combination Figure 2 and Figure 3Two second fans 26 are fixedly connected to the bottom of the outer wall of the base 2. Two pads 21 are fixedly connected to the bottom of the inner wall of the base 2. Heating copper pipes 23 are placed on the pads 21. The heating copper pipes 23 and heating heads 20 work together for heating. The heating copper pipes 23 are arranged between the two pads 21. The two ends of the heating copper pipes 23 pass through the base 2 and are fixedly connected to the heating heads 20. The bottom of the hydraulic oil tank body 3 is provided with heat dissipation fins 19. The heat dissipation fins 19 dissipate heat from the hydraulic oil tank body 3. An oil pump 29 is fixedly connected to the front side of the outer wall of the outer shell 1. When the oil pump 29 works, it can transport the oil in the hydraulic oil tank body 3 into the first conveying copper pipe 11 and the second conveying copper pipe 18 to disperse the oil and facilitate heat dissipation and heating. The output end of the oil pump 29 is connected to a second conveying copper pipe 18, and the input end of the oil pump 29 is connected to a first conveying copper pipe 11. A first fan 7 is fixedly connected to the left side of the outer wall of the outer casing 1. When the first fan 7 is working, it can input gas into the hydraulic oil tank body 3 to blow on the heat dissipation fins 19, the first conveying copper pipe 11, and the second conveying copper pipe 18. A connecting pipe 8 is connected to the bottom end of the first fan 7, and a U-shaped pipe 9 is connected to the bottom end of the connecting pipe 8. A branch pipe 10 is connected to one side of the outer ring of the U-shaped pipe 9 to blow the heat in the hydraulic oil tank body 3 out through the first filter screen 13. A nozzle 12 is connected to the right end of the branch pipe 10, and a first filter screen 13 is provided on the right side of the inner wall of the outer casing 1.
[0034] Combination Figure 4 and Figure 5 Two limiting shells 24 are fixedly connected to the bottom of the outer wall of the base 2. A second filter plate 25 is slidably connected through one side of each limiting shell 24. The second filter plate 25 can filter the gas entering when the second fan 26 is working. A control panel 5 is provided on the rear side of the outer wall of the outer shell 1. A signal receiver 6 is provided at the bottom of the control panel 5. A sealing gasket 16 is provided on the left side of the baffle 14. The sealing gasket 16 can increase the sealing between the baffle 14 and the outer shell 1. A protrusion 17 is fixedly connected to the right side of the baffle 14. The protrusion 17 facilitates the upward movement of the baffle 14 for removal. Two support plates 27 are fixedly connected to the bottom of the outer wall of the base 2.
[0035] Working principle: When using the hydraulic oil tank, the temperature sensor 4 detects the temperature. When the detected temperature is lower than the preset standard, the signal receiver 6 receives the signal, and the control panel 5 controls the second fan 26 to work. At the same time, the heating head 20 and the heating copper pipe 23 work to heat the oil, allowing hot air to enter and exit the outer casing 1. The second filter plate 25 filters the incoming air. Then, the oil pump 29 is started to draw the oil in the hydraulic oil tank body 3 into the first delivery copper pipe 11, then into the second delivery copper pipe 18, and then back into the hydraulic oil tank body 3 for circulation, which can accelerate the temperature rise. At the same time, the baffle 14 closes the tank to dissipate heat. The fins 19 dissipate heat within the outer casing 1, working together for heating. When the temperature sensor 4 detects an excessively high temperature, the oil pump 29 restarts, circulating the oil in the hydraulic oil tank 3. Then, the baffle 14 is removed from the guide rail 15, allowing the heat dissipation fins 19 to dissipate heat. The first fan 7 is activated, and the U-shaped pipe 9 and branch pipe 10 transport the gas, which is then sprayed from the nozzle 12. The nozzle 12 is positioned opposite the heat dissipation fins 19, the first conveying copper pipe 11, and the second conveying copper pipe 18, blowing hot air out from the first filter screen 13 for heat dissipation. This ensures that the oil temperature is neither too high nor too low, improving the performance.
