Description

Technical Field

[0001] The utility model relates to the technical field of oil tank design, in particular to a constant temperature heating oil tank and a lubricating device. Background Art

[0002] Large-scale mechanical equipment is equipped with a reducer for speed and torque control. The reducer must be equipped with a lubrication device to lubricate and dissipate heat for the internal gears, bearings and other mechanical structures to ensure the service life of the mechanical equipment. Conventional lubrication methods generally include two situations: 1) Oil bath lubrication: that is, the lubricating oil is directly added to the reducer. This lubrication method is generally used for equipment with low frequency of use and small reducers; 2) Independent lubrication: that is, there is no oil in the reducer, and the reducer is lubricated by an independent lubrication device. This lubrication method is generally used for equipment with high frequency of use, large reducers, many bearings, large size, and relatively high requirements for temperature, flow, and lubrication accuracy.

[0003] Independent lubrication devices are generally equipped with oil tanks, oil pumps, pipelines, valves, control systems and other equipment. At present, independent lubrication has the following main disadvantages:

[0004] 1. The oil circulation in the oil tank is insufficient and the oil heating is uneven, resulting in unstable oil temperature during operation, many faults, and the main reducer shutdown.

[0005] 2. The heater is installed too centrally and the operating temperature of the heater body is too high. There is no intelligent temperature control function. The oil is not fully circulated during the heating process, resulting in local high-temperature heating of the oil near the heater, causing carbonization and deterioration.

[0006] Due to the above problems, the lubrication device operates unstably, the lubrication effect is poor, the service life of the lubricating oil is short, the maintenance cost is increased, and the economic benefits are seriously affected.

[0007] Therefore, there is an urgent need to solve the problem of heating the oil tank in the independent lubrication device to ensure the lubrication effect. Utility Model Content

In the following description, many specific details are provided to provide a full understanding of the embodiments of the present utility model.

In other cases, known methods, devices, implementations or operations are not shown or described in detail to avoid blurring the various aspects of the present utility model.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those shown or described.

[0036] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Some embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] In order to solve the technical problems existing in the prior art, the embodiment of the utility model provides a constant temperature heating oil tank, which comprises: a main oil tank and a secondary water tank arranged at the bottom of the outer side of the main oil tank;

[0039] Wherein, a baffle is arranged inside the main oil tank for realizing the lateral flow of the oil in the main oil tank; a circulation mechanism is arranged outside the main oil tank for realizing the longitudinal flow of the oil in the main oil tank;

[0040] A plurality of constant temperature heaters are arranged inside the auxiliary water tank.

[0041] It is understandable that, under normal circumstances, the interior of the auxiliary water tank is filled with dielectric water, which is heated by a constant temperature heater, and the dielectric water evenly transfers the temperature to the main oil tank, thereby heating the oil in the tank.

[0042] It is understandable that the specific heat of water is greater than that of oil, so the temperature rises and falls more gradually. Therefore, the auxiliary water tank uses water as the heat transfer medium, and the constant temperature heater does not come into direct contact with the oil, which effectively solves the problem of oil carbonization caused by excessive local temperature near the constant temperature heater.

[0043] For example, see Figure 1 , showing a structural schematic diagram of a constant temperature heating oil tank.

[0044] like Figure 1 As shown, the constant temperature heating oil tank includes a main oil tank 1 and an auxiliary water tank 2. The auxiliary water tank 2 is arranged outside the bottom of the main oil tank 1 and contacts the bottom of the main oil tank 1. When the auxiliary water tank 2 is filled with medium water, the medium water in the auxiliary water tank 2 contacts the entire bottom surface of the main oil tank 1 to ensure heat conduction efficiency.

[0045] A baffle plate 3 is provided inside the main oil tank 1 , and the baffle plate 3 can enable the oil in the main oil tank 1 to fully flow horizontally.

[0046] A circulation mechanism 4 is provided on the external suspension of the main oil tank 1, one end of the circulation mechanism 4 extends from the bottom of the main oil tank 1 into the oil tank to absorb oil, and the other end extends from the top of the main oil tank 1 into the oil tank to discharge oil, so that the oil rolls up and down in the main oil tank 1 to form a three-dimensional longitudinal circulation; through the provided baffle 3 and the circulation mechanism 4, the oil in the main oil tank 1 realizes an overall horizontal and vertical circulation, ensuring that the temperature of the oil at each position in the main oil tank 1 is balanced.

[0047] like Figure 1 As shown, three constant temperature heaters 5 are arranged inside the auxiliary water tank 2, and the three constant temperature heaters 5 are evenly arranged inside the auxiliary water tank 2 to ensure uniform heating of the medium water.

[0048] In some feasible embodiments, based on the aforementioned solution, the baffle is vertically arranged on the inner bottom plate of the main oil tank.

[0049] For example, Figure 1 As shown, the baffle plate 3 is vertically installed on the bottom plate in the main oil tank 1. When the oil in the main oil tank 1 flows horizontally, it will be deflected after encountering the baffle plate 3, so that the oil can flow fully in the horizontal direction. In addition, multiple baffle plates 3 can be adaptively set, and the specific number of settings is determined according to actual conditions.

[0050] In some feasible embodiments, based on the above solution, the circulation mechanism includes a circulation pump, an oil suction pipe and an oil outlet pipe;

[0051] The circulating pump is vertically hung on the side of the main oil tank;

[0052] One end of the oil suction pipe is connected to the oil suction port of the circulating pump, and the other end enters the interior of the main oil tank from the bottom of the main oil tank;

[0053] One end of the oil outlet pipe is connected to the oil outlet of the circulating pump, and the other end enters the interior of the main oil tank from the top of the main oil tank.

[0054] It should be noted that the oil suction pipe and the oil outlet pipe can be provided with multiple branches, and the multiple oil suction branch pipes and the multiple oil outlet branch pipes can be evenly distributed in the main oil tank 1 at a certain distance to ensure the vertical and three-dimensional circulation of the oil in the oil tank; at the same time, the multiple oil suction branch pipes and the multiple oil outlet branch pipes can also ensure that when the oil circulates in the three-dimensional longitudinal flow, the entire horizontal surface circulating at the top and bottom of the main oil tank 1 is uniform, further ensuring the balance of oil at various positions in the main oil tank 1.

[0055] For example, see Figure 2 , showing a structural schematic diagram of a circulation mechanism.

[0056] like Figure 2 As shown, the circulation mechanism 4 includes a circulation pump 41, an oil suction pipe 42 and an oil outlet pipe 43; wherein, one end of the oil suction pipe 42 is connected to the oil suction port at the lower end of the circulation pump 41, and the other end extends into the bottom of the main oil tank 1 to suck oil; one end of the oil outlet pipe 43 is connected to the oil outlet at the upper end of the circulation pump 41, and the other end extends into the top of the main oil tank 1 to discharge oil.

[0057] When oil circulation is required, the circulation pump 41 is started, and the oil suction pipe 42 sucks oil from the bottom of the main oil tank 1. The sucked oil is brought to the oil outlet pipe 43 through the circulation pump 41, and the oil outlet pipe 43 puts the oil into the top of the main oil tank 1. Due to the gravity of the oil itself or the impact of the power of the oil pump on the oil, the oil continues to move downward after entering the main oil tank 1, thereby realizing the longitudinal flow of the oil in the main oil tank; and the depth of the oil outlet pipe extending into the main oil tank 1 or the power of the circulation pump 41 can be adjusted to increase the longitudinal flow speed, depth and efficiency of the oil in the main oil tank 1, thereby enhancing the longitudinal mixing effect of the oil.

[0058] In some feasible embodiments, based on the above-mentioned solution, heat dissipation fins are evenly arranged on the inner bottom plate of the main oil tank.

[0059] For example, Figure 1 As shown, a plurality of heat dissipation fins 6 are evenly arranged at the bottom of the main oil tank 1 to increase the heat transfer area of ​​the oil tank bottom plate and ensure even heat transfer between the auxiliary water tank and the oil tank.

[0060] In some feasible embodiments, based on the above solution, it also includes:

[0061] A reserve water tank is communicated with the auxiliary water tank and is used to replenish medium water to the auxiliary water tank.

[0062] It is understandable that a certain amount of water is stored in the reserve water tank to avoid frequent water replenishment and achieve automatic water replenishment within a regular period.

[0063] For example, Figure 1 As shown, the reserve water tank 7 is arranged on the right side of the auxiliary water tank 2 and is connected to the auxiliary water tank 2 to ensure that the water stored in the reserve water tank 7 can flow into the auxiliary water tank 2 at any time.

[0064] It should be noted that, in order to improve the heat transfer efficiency, the space between the auxiliary water tank and the oil tank bottom plate should be filled with water without air, while the reserve water tank can fill the auxiliary water tank with water. In addition, since the reserve water tank 7 is connected to the auxiliary water tank 2, the air in the auxiliary water tank 2 can be discharged through the reserve water tank 7, and the problem of water overflow caused by water expansion when the auxiliary water tank 2 is heated can also be solved.

[0065] In some feasible embodiments, based on the above scheme, a first temperature sensor is provided inside the main oil tank, a second temperature sensor is provided inside the auxiliary water tank, and both the first temperature sensor and the second temperature sensor are communicatively connected to the constant temperature heater.

[0066] It can be understood that the first temperature sensor is used to monitor the temperature of the oil inside the main oil tank, and the second temperature sensor is used to monitor the temperature of the medium water inside the auxiliary water tank.

[0067] It should be noted that the constant temperature heater can achieve heating between 0 and 80°C. The constant temperature heater has its own sensor and controller to automatically monitor and control the heating temperature of the heater itself. The constant temperature heater communicates with the first temperature sensor and the second temperature sensor to ensure a constant oil temperature in the main oil tank.

[0068] For example, Figure 1 As shown, two first temperature sensors 8 are arranged in the main oil tank 1, one of which is used as a backup, and two second temperature sensors 9 are arranged in the auxiliary water tank 2, one of which is used as a backup; in this example, both the first temperature sensor and the second temperature sensor are platinum thermistors; the platinum thermistor in the auxiliary water tank 2 is used to detect the temperature of the auxiliary water tank 2 to prevent the platinum thermistor in the main oil tank 1 from malfunctioning, and the water temperature measured by the platinum thermistor of the auxiliary water tank 2 can be controlled to 50°C, and a serious fault will be reported if it exceeds 50°C. Therefore, in this example, it is used to play a role of safety protection to prevent the sensor or controller of the constant temperature heater itself from being damaged, resulting in excessive water temperature heating and excessive oil temperature.

[0069] In some feasible embodiments, based on the above-mentioned solution, the outer side of the main oil tank and the outer side of the auxiliary water tank are both provided with a thermal insulation layer.

[0070] For example, Figure 1As shown, the main oil tank 1 and the auxiliary water tank 2 are provided with an insulation layer 10 on the whole outer side, which ensures that the temperature drop of the oil in the oil tank is not more than 2°C within 12 hours, realizes the insulation function, and keeps the oil temperature of the oil tank constant when the machine is stopped. When the main engine is started next time, it can be started directly without heating again or the heating time is very short. At the same time, energy saving is achieved through insulation, and repeated heating and cooling of the oil is avoided.

[0071] In some feasible embodiments, based on the above-mentioned solution, a three-way valve is provided at the oil supply outlet of the main oil tank.

[0072] For example, Figure 1 As shown, a three-way valve 11 is provided at the outlet of the oil supply line of the main oil tank 1; in the temperature rising stage, the three-way valve 11 switches to the internal circulation channel of the main oil tank and does not supply oil to the outside to reduce heat loss. When the oil temperature reaches the requirement, the three-way valve 11 switches to the external oil supply channel.

[0073] In some feasible embodiments, based on the above-mentioned solution, a liquid level meter is provided inside the auxiliary water tank.

[0074] For example, Figure 1 As shown, the liquid level meter 12 is arranged at the connection point between the auxiliary water tank 2 and the reserve water tank 7, and is used to detect the liquid level in the auxiliary water tank 2. When the liquid level in the auxiliary water tank 2 is too low and does not meet the requirements, the medium water in the auxiliary water tank 2 is supplemented through the reserve water tank 7.

[0075] Based on the same utility model concept, an embodiment of the utility model also provides a lubrication device, including a constant temperature heating oil tank as described in the above embodiment.

[0076] It is understandable that the lubrication device is provided with an oil pump, a pipeline, a valve, a control system and other equipment in addition to the constant temperature heating oil tank. The lubrication device provided with the constant temperature heating oil tank runs more stably and has a better lubrication effect.
