Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil tank technology, specifically a temperature regulating device for a hydraulic oil tank. Background Technology

[0002] Hydraulic oil tanks are a crucial component of hydraulic systems. Their primary function is to store hydraulic fluid, while also serving purposes such as heat dissipation, impurity settling, and air removal. The design of hydraulic oil tanks must consider components such as volume, structure, baffles, radiator, filter, oil level gauge, thermometer, breather, cleaning port, and drain plug to ensure the tank meets the operational requirements of the hydraulic system. Hydraulic oil tanks are available in two types: open and closed. Open tanks allow the fluid level to communicate with the atmosphere and are suitable for general hydraulic systems; closed tanks isolate the fluid level from the atmosphere and are suitable for underwater applications and hydraulic systems with strict requirements for stability and noise reduction. Hydraulic oil tanks are typically made of corrosion-resistant steel, but stainless steel or aluminum alloys can also be used.

[0003] Traditional hydraulic oil tank temperature regulation devices can only heat the hydraulic oil from one side, resulting in uneven internal temperature and failing to meet the requirements for hydraulic oil temperature control. Therefore, a new hydraulic oil tank temperature regulation device is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic oil tank temperature regulation device, which has the advantages of comprehensive control over hydraulic oil temperature. It solves the problem that hydraulic oil tank temperature regulation devices can only heat hydraulic oil from one side, resulting in uneven internal temperature and thus failing to meet the requirements for hydraulic oil temperature regulation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temperature regulating device for a hydraulic oil tank, comprising a hydraulic oil tank, wherein two inlet and outlet ports are provided inside the upper side of the hydraulic oil tank, two temperature displays are inserted and installed on the front end face of the hydraulic oil tank, and a heating device is provided inside the hydraulic oil tank;

[0007] Furthermore, a flow guiding assembly is provided on the outside of the fixed box. The flow guiding assembly includes two motors fixedly installed on the front end face of the fixed box and a flow guiding plate fixedly connected to the output end of the motors.

[0008] Furthermore, the side of the first connecting pipe away from the fixed box is connected to a second connecting pipe, and the upper side of the second connecting pipe is inlaid with multiple breathable and liquid-resistant membranes.

[0009] Furthermore, a sealing ring is fitted at the connection between the first connecting pipe and the second connecting pipe, and the plurality of the air-permeable and liquid-resistant membranes are arranged equidistantly in the transverse direction.

[0010] Furthermore, a cooling mechanism is provided on the right side of the hydraulic oil tank.

The temperature regulation device of the hydraulic oil tank achieves the purpose of controlling and regulating the temperature of hydraulic oil at different heights through the heating device and the vent-proof liquid-blocking film on the upper side of the second connecting pipe, so as to control and regulate the overall temperature of the hydraulic oil.

[0016] 2. The temperature regulation device of the hydraulic oil tank can achieve angle adjustment within the fixed box by driving the guide plate with a motor.

Detailed Implementation

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0024] Please see Figures 1 to 4 This embodiment provides a temperature regulating device for a hydraulic oil tank, comprising a hydraulic oil tank 1. Two inlet / outlet ports 2 are located inside the upper side of the hydraulic oil tank 1. Two temperature displays 4 are connected and installed on the front end of the hydraulic oil tank 1. A heating device 13 is installed inside the hydraulic oil tank 1. The heating device 13 includes a fixed housing 14 connected to the inner top wall of the hydraulic oil tank 1, two heating wires 15 fixedly installed inside the fixed housing 14, two exhaust fans 16 fixedly installed inside the fixed housing 14, two third connecting pipes 17 connected to the lower side of the fixed housing 14, and two first connecting pipes 10 connected to the side of the fixed housing 14.

[0025] The first connecting pipe 10 is connected to the second connecting pipe 11 on the side away from the fixed box 14. Multiple breathable liquid-blocking membranes 12 are embedded in the upper side of the second connecting pipe 11. A sealing ring is fitted at the connection between the first connecting pipe 10 and the second connecting pipe 11. The multiple breathable liquid-blocking membranes 12 are arranged horizontally at equal intervals. A cooling mechanism is provided on the right side of the hydraulic oil tank 1. The cooling mechanism includes a pump body 5 connected to the right side of the hydraulic oil tank 1, a cooling box 6 connected to the right side of the pump body 5, a fixed box 7 fixedly connected to the inner wall of the cooling box 6, a right-end coolant injection pipe 8 connected to the upper side of the cooling box 6, and a right-end coolant discharge pipe 9 connected to the lower side of the cooling box 6. A dustproof net 3 is embedded in the upper side of the hydraulic oil tank 1. The lower side of the dustproof net 3 is connected to the upper side of the fixed box 14. The cooling box 6 is connected to the back of the hydraulic oil tank 1. The suction end of the pump body 5 is connected to the front end of the hydraulic oil tank 1. The discharge end of the pump body 5 is connected to the front end of the cooling box 6.

[0026] Example 2:

[0027] Please see Figure 1 , Figure 3 and Figure 4 Based on Embodiment 1, a flow guiding assembly is provided on the outside of the fixed box 14. The flow guiding assembly includes two motors 19 fixedly installed on the front end face of the fixed box 14 and a flow guiding plate 18 fixedly connected to the output end of the motors 19.

[0028] By adopting the above technical solution, the exhaust air can be controlled to flow into different pipes when the output end of motor 19 drives the guide plate 18, ensuring that the temperature of hydraulic oil at different positions remains synchronized. The two motors 19 are controlled by the same controller, thus achieving synchronization.

[0029] The working principle of the above embodiments is as follows:

[0030] Hydraulic oil is injected through inlet / outlet 2. Two temperature displays 4 monitor the bottom and top temperatures of the hydraulic oil in real time. When there is a temperature difference between the bottom and top oil, such as the bottom hydraulic oil being lower than the top temperature, the motor 19 is started to drive the guide plate 18 to rotate and fit against the lower side of the inner wall of the fixed box 14, placing it on the third connecting pipe 17. The exhaust fan 16 and the heating wire 15 are then turned on. The exhaust fan 16 absorbs the heat generated by the heating wire 15 and discharges it into the first connecting pipe 10, exiting through the breathable liquid-blocking membrane 12 to raise the temperature of the lower hydraulic oil. The temperature of the hydraulic oil is controlled by the temperature display 4 on the lower side. Once the temperature is equal to the temperature above, the heat transfer is stopped. If the temperature of the hydraulic oil above is lower than that below, the guide plate 18 is rotated and tilted to contact the end of the first connecting pipe 10, allowing the hot air to be discharged from the third connecting pipe 17 to achieve temperature control. When the overall temperature is high, the pump body 5 absorbs the hydraulic oil and discharges it into the fixed box 7. Then, the coolant is injected into the cooling box 6 from the coolant injection pipe 8 and discharged from the coolant drain pipe 9. The coolant wraps around the outside of the hydraulic oil to cool it down quickly.

[0031] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
