Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a fuel heating system for an impact-type mobile crushing station. Background Art
[0002] Mobile impact crushing station is a kind of mining material crushing and pre-screening equipment, which is mainly used in mines in high-altitude areas (above 2000m above sea level). However, in actual use, due to the large temperature difference between day and night in early spring or autumn and winter in high-altitude areas, sometimes the temperature difference between day and night is as high as 20℃ or more, which brings the problem of diesel selection and supply. When the temperature is high during the day, it can work normally with No. 0 diesel, but when the temperature drops sharply at night, it is necessary to use No. -10 or even -20 diesel. If the diesel is not replaced, the diesel will wax, resulting in insufficient power or shutdown of the equipment. However, replacing diesel according to the ambient temperature is likely to cause confusion in diesel supply. At the same time, low-temperature diesel is not only expensive, but also increases fuel consumption, which in turn increases the operating cost of the equipment. Therefore, a heating system is required to effectively heat the low-temperature diesel.
[0003] For example, in the patent document with patent publication number CN206386217U, a diesel engine low-temperature heating system is disclosed, which includes a diesel engine, a control device, a small gasoline generator and a heating device. The control device controls the opening and closing of the heating device. The diesel engine includes a diesel tank, a diesel oil pipe and a coolant. The heating device includes a diesel tank heating device, a diesel oil pipe heating device and a coolant electric heating device.
[0004] According to the existing technical literature, the heating system can generate electricity through a gasoline generator and then heat the diesel tank, diesel fuel pipe and coolant through electric heating, thereby increasing the temperature of the diesel tank, diesel fuel pipe and coolant, so that the diesel engine can start normally in a low temperature environment. However, heating through electric heating consumes too much energy, which greatly increases the operating cost and the economic efficiency of the equipment is poor.
[0005] To this end, the utility model optimizes and improves the problem of excessive energy consumption in the heating method in the prior art, and hereby proposes a new heating system that performs composite heating through electric heating and hot water heating, so as to better solve the problems in the prior art.

DETAILED DESCRIPTION
[0030] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. The specific structure of the utility model is as follows Figure 1-Figure 8 as shown in .
[0031] A fuel heating system for an impact mobile crushing station, comprising a fuel tank 1, an oil outlet port of the fuel tank 1 is fixedly connected to an oil inlet end of a first oil inlet pipe 2 and the two are internally connected, the oil outlet end of the first oil inlet pipe 2 is fixedly connected to an integrated heating component 3 and the two are internally connected, the integrated heating component 3 is fixedly connected to an oil inlet end of a second oil inlet pipe 4 and the two are internally connected, the oil outlet end of the second oil inlet pipe 4 is fixedly connected to an oil inlet port of a diesel engine 5 and the two are internally connected, the oil outlet port of the diesel engine 5 is fixedly connected to a first oil return pipe 2, and the oil outlet port of the diesel engine 5 is connected to a first oil return pipe 3. The oil inlet end of the pipe 6 is fixedly connected and the two are internally connected. The oil outlet end of the first oil return pipe 6 is fixedly connected to the integrated heating component 3 and the two are internally connected. The integrated heating component 3 is fixedly connected to the oil inlet end of a second oil return pipe 7 and the two are internally connected. The oil outlet end of the second oil return pipe 7 is fixedly connected to the oil inlet port of the fuel tank 1 and the two are internally connected. It also includes a coolant circulation pipeline. In the working state, the coolant circulation pipeline is used to circulate cooling water between the diesel engine 5 and the integrated heating component 3.
[0032] The fuel tank 1, the integrated heating component 3 and the diesel engine 5 are fixedly arranged at corresponding work positions, wherein the fuel tank 1 and the integrated heating component 3 are connected through the first oil inlet pipe 2 and the second oil return pipe 7, and the integrated heating component 3 and the diesel engine 5 are connected through the second oil inlet pipe 4 and the first oil return pipe 6, so that the diesel in the fuel tank 1 flows into the integrated heating component 3 through the first oil inlet pipe 2, and then flows into the diesel engine 5 through the second oil inlet pipe 4 to burn and do work, thereby providing power for the machine, and the incompletely burned diesel returns to the integrated heating component 3 through the first oil return pipe 6, and finally returns to the fuel tank 1 through the second oil return pipe 7.
[0033] During the start-up phase of the diesel engine 5, the diesel engine 5 is started by using the heating filter element or other auxiliary starting device provided by the diesel engine 5, so that it runs at idle speed and low load, and then the diesel engine 5 drives the AC generator to provide heating power for the integrated heating component 3, and heats the inlet and return oil of the diesel engine 5. Then the electric heating structure in the integrated heating component 3 works, thereby heating the low-temperature diesel flowing into the diesel engine 5 through the first oil inlet pipe 2 and the second oil inlet pipe 4 by electric heating, so that it heats up quickly, thereby gradually increasing the speed and load rate of the diesel engine 5, and at the same time making the temperature of the coolant of the diesel engine 5 rise quickly and be in a stable state.

[0034] At the same time, when the incompletely burned high-temperature diesel flows through the integrated heating component 3 through the first return oil pipe 6 and the second return oil pipe 7, the heat of the returning diesel can be reused through the heat exchange of the integrated heating component 3 to further heat the low-temperature diesel flowing to the diesel engine 5, and then flows back to the fuel tank 1 to increase the overall temperature of the diesel.

[0036] As the diesel engine 5 continues to work, the temperature of the coolant inside it rises rapidly, and enters the interior of the integrated heating assembly 3 through the water inlet pipe 8, thereby heating the low-temperature diesel flowing to the diesel engine 5. After completing the heat exchange, the coolant returns to the diesel engine 5 through the water outlet pipe 9, thereby absorbing heat and continuing to complete the next cycle.
[0037] In any of the above schemes, preferably, water inlet valves 10 are respectively connected in series at both ends of the water inlet pipe 8, and water outlet valves 11 are respectively connected in series at both ends of the water outlet pipe 9.
[0038] The opening and closing states of the coolant circulation pipeline can be controlled by the two water inlet valves 10 and the two water outlet valves 11, and the coolant flow rate inside the pipeline can be adjusted at the same time.
[0039] In any of the above schemes, it is preferred that the integrated heating assembly 3 includes an oil-water heat exchanger 12 with a flow cavity arranged therein, and an oil inlet heat exchange tube 13 and an oil return heat exchange tube 14 are arranged in the inner cavity of the oil-water heat exchanger 12 at intervals along its width direction, and the ends of the oil inlet heat exchange tube 13 and the oil return heat exchange tube 14 respectively penetrate the sealed mounting holes at the corresponding ends of the oil-water heat exchanger 12 and extend to the outside thereof, the oil inlet end of the oil inlet heat exchange tube 13 is fixedly connected to the oil outlet end of the first oil inlet pipe 2 and the two are internally connected, the oil outlet end of the oil inlet heat exchange tube 13 is fixedly connected to the oil inlet end of the second oil inlet pipe 4 and the two are internally connected, the oil inlet end of the oil return heat exchange tube 14 is fixedly connected to the oil outlet end of the first oil return pipe 6 and the two are internally connected, the oil outlet end of the oil return heat exchange tube 14 is fixedly connected to the oil inlet end of the second oil return pipe 7 and the two are internally connected, and an electric heating module is provided below the oil-water heat exchanger 12.
[0040] A flow cavity for water flow is formed inside the oil-water heat exchanger 12. The first oil inlet pipe 2, the oil inlet heat exchange pipe 13 and the second oil inlet pipe 4 are connected in sequence. The low-temperature diesel flowing to the diesel engine 5 flows through the three in sequence and exchanges heat with the water in the flow cavity in the oil inlet heat exchange pipe 13, thereby heating the diesel. The first oil return pipe 6, the oil return heat exchange pipe 14 and the second oil return pipe 7 are connected in sequence. The incompletely burned diesel flowing back to the fuel tank 1 flows through the three in sequence and exchanges heat with the water in the flow cavity in the oil return heat exchange pipe 14.
[0041] The corresponding positions where the oil inlet heat exchange pipe 13 and the oil return heat exchange pipe 14 pass through the oil-water heat exchanger 12 are sealed to avoid water leakage.
[0042] In any of the above schemes, it is preferred that the electric heating module includes an electric heater 15 fixedly arranged below the oil-water heat exchanger 12, a water pump is arranged inside the electric heater 15, a water outlet port of the electric heater 15 is fixedly connected to a first hose 16 and the two are internally connected, a water inlet port of the electric heater 15 is fixedly connected to a second hose 17 and the two are internally connected, a first water pipe joint 18 and a second water pipe joint 19 are integrally formed on the oil-water heat exchanger 12 at intervals, the other end of the first hose 16 is fixedly connected to the first water pipe joint 18 and the two are internally connected, and the other end of the second hose 17 is fixedly connected to the second water pipe joint 19 and the two are internally connected.
[0043] The electric heater 15 is a prior art product, and is internally provided with necessary functional elements for water circulation, such as a water pump and a controller. Under the electric heating effect of the electric heater 15, the circulating water can be heated, and then the high-temperature circulating water is sent into the first hose 16 through the water pump. The high-temperature circulating water further enters the first water pipe joint 18 through the first hose 16, and then flows into the flow cavity inside the oil-water heat exchanger 12 through the first water pipe joint 18, and exchanges heat with the low-temperature diesel in the oil inlet heat exchange pipe 13. Then the circulating water that has completed the heat exchange flows out of the oil-water heat exchanger 12 through the second water pipe joint 19, and further flows back into the electric heater 15 through the second hose 17. Through continuous circulation, the heat can be quickly transferred to the low-temperature diesel, so that it can be heated up quickly.

[0045] After the low-temperature diesel is quickly heated up by electric heating, the diesel engine 5 starts to work continuously at a high speed and a high load rate. At this time, the coolant in the diesel engine enters the third water pipe joint 20 through the water inlet pipe 8, and then enters the internal flow cavity of the oil-water heat exchanger 12 through the third water pipe joint 20, thereby heating the low-temperature diesel flowing to the diesel engine 5. After completing the heat exchange, the coolant returns to the diesel engine 5 through the fourth water pipe joint 21 and the water outlet pipe 9 in turn.
[0046] In any of the above schemes, it is preferred that an expansion water tank 22 is provided above the oil-water heat exchanger 12, and a water supply pipe joint 23 and a degassing pipe joint 24 are integrally formed on the second water pipe joint 19 at intervals, and the expansion water tank 22 is connected to the water supply pipe joint 23 through a water supply pipe 25, and the expansion water tank 22 is connected to the degassing pipe joint 24 through a degassing pipe 26.
[0047] The water supply pipe joint 23 is integrally formed with the second water pipe joint 19 and is internally connected. The water in the expansion water tank 22 enters the second water pipe joint 19 through the water supply pipe 25 and the water supply pipe joint 23, and then enters the second hose 17 to replenish the water circulation in the electric heating module. An observation port is set on the expansion water tank 22 to facilitate observation of the liquid level.
[0048] At the same time, a pressure valve is arranged on the degassing pipe joint 24 , and the bubbles in the entire water circulation pipeline of the electric heating module enter into the expansion water tank 22 through the degassing pipe joint 24 and the degassing pipe 26 .
[0049] In any of the above solutions, preferably, the integrated heating assembly 3 further includes a mounting frame 27 , and the oil-water heat exchanger 12 , the electric heater 15 and the expansion water tank 22 are respectively fixedly mounted at corresponding positions of the mounting frame 27 .
[0050] Each component is installed and fixed by a fixing frame 27 .
[0051] In any of the above solutions, preferably, a protective plate 28 is fixedly connected to the outer side of the installation frame 27 .
[0052] The various structures of the integrated heating assembly are protected by the protective plate 28 , and the corresponding oil inlet and return pipes and water inlet and outlet pipes pass through the through holes at corresponding positions on the protective plate 28 .
[0053] Specific working principle:
[0054] First, during the start-up phase of the diesel engine 5, the diesel engine 5 is started using its own heating filter or other auxiliary starting devices. At this time, the diesel in the fuel tank 1 flows into the oil inlet heat exchange pipe 13 through the first oil inlet pipe 2, and then flows into the diesel engine 5 through the second oil inlet pipe 4 to burn and do work, causing it to run at idle speed and low load. The incompletely burned diesel returns to the oil return heat exchange pipe 14 through the first oil return pipe 6, and finally returns to the fuel tank 1 through the second oil return pipe 7.
[0055] After that, the water inlet valve 10 and the water outlet valve 11 are closed, and water is added to the second hose 17 through the expansion tank 22 and the water supply pipe 25, and the electric heater 15 is turned on to heat the added water and circulate it. When it flows through the flow cavity of the oil-water heat exchanger 12, the high-temperature water exchanges heat with the low-temperature diesel in the oil inlet heat exchange pipe 13, so that the low-temperature diesel is heated, and the speed and load rate of the diesel engine 5 can be continuously improved. At the same time, under the continuous operation of the diesel engine 5, the coolant inside it is quickly heated, and when the coolant temperature of the diesel engine 5 reaches the target value (generally about 80°C) and remains stable, the electric heater 15 is turned off.
[0056] After that, the water inlet valve 10 and the water outlet valve 11 are opened, so that the high-temperature coolant in the diesel engine 5 enters the flow cavity of the oil-water heat exchanger 12 through the water inlet pipe 8, and then continues to heat the diesel flowing to the diesel engine 5, so as to maintain a certain temperature, and then the coolant after the heat exchange is completed returns to the diesel engine 5 through the water outlet pipe 9. Through continuous circulation, the coolant can be continuously heated by the working temperature of the diesel engine 5, and then the diesel is continuously heated by the high-temperature coolant, thereby ultimately ensuring that the diesel engine 5 can continue to operate well.
