Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat dissipation equipment for warehouse clearing machines, and in particular to a water-cooled heat dissipation device for warehouse clearing machines. Background Technology
[0002] The cleaning machine is mainly used for cleaning mine silos, coal bunkers, and water bunkers. Before cleaning, the cleaning machine first breaks up and washes away the caking materials with high-pressure water flow, thus separating the caking materials from the machine body. The high-pressure water flow is achieved by using an external water source in conjunction with a high-pressure pump and pipeline.
[0003] During the operation of the cleaning machine, core components such as the motor and hydraulic system will generate a lot of heat due to long-term high-load operation. Especially in underground coal mines, the working environment is closed and the air circulation is poor. The equipment needs to operate continuously for a long time, and the heat is difficult to dissipate effectively, which can easily lead to a sharp rise in component temperature.
[0004] In the existing technology, air cooling and water cooling are commonly used as heat dissipation methods. Among them, air cooling has exposed many drawbacks in the complex and harsh working environment where the clearance machine is located. Air cooling relies on air flow to remove heat. In enclosed or dusty environments, air flow is limited, and dust can easily block the heat dissipation channels, which seriously reduces the heat dissipation effect.
[0005] Regarding water cooling, since the main oil tank of the cleaning machine is close to or located in the cab, the surrounding usable space is very limited. This presents problems such as difficulty in structural design and low compatibility with the working characteristics of the cleaning machine, resulting in unsatisfactory heat dissipation and easy to affect the normal operation of the equipment. Utility Model Content
[0006] This application provides a water-cooled heat dissipation device for a warehouse cleaning machine, which can effectively improve the heat dissipation efficiency of the main oil tank of the warehouse cleaning machine through water-cooled heat exchange, and ensure that the heat dissipation components of the warehouse cleaning machine operate normally for a long time.
[0007] This application provides a water-cooled heat dissipation device for a cleaning machine, used for heat dissipation of the main oil tank of the cleaning machine. The main oil tank is provided with a partition to divide the inner cavity of the main oil tank into a first chamber and a second chamber. The first chamber is provided with an oil return port and a high-temperature oil outlet at the bottom. The second chamber is provided with an oil outlet and a low-temperature oil inlet at the bottom. The main oil tank supplies oil to various oil-using equipment of the cleaning machine through the oil return port and the oil outlet in conjunction with the pipeline.
[0008] The water-cooled heat dissipation device of the clearing machine also includes a heat dissipation oil tank, which is located below the main oil tank. The heat dissipation oil tank has a high-temperature oil inlet and a low-temperature oil outlet. The high-temperature oil inlet is connected to the high-temperature oil outlet through a first pipe, and the low-temperature oil outlet is connected to the low-temperature oil inlet through a second pipe. A cooling water passage is provided on the outside of the heat dissipation oil tank. The inlet of the cooling water passage is connected to external water, and the outlet of the cooling water passage is provided at the end away from the inlet in the passage direction, so as to cool the heat dissipation oil tank by water-cooled heat exchange.
[0009] In one possible implementation, the cooling oil tank is fixed to the track chassis of the cleaning machine.
[0010] In one possible implementation, the partition is a multi-layered partition distributed in parallel, and heat-insulating gaps are provided between adjacent plates of the multi-layered partition.
[0011] In one possible implementation, the radiator is a frame structure, and the cooling water passages are integrated and arranged on the surface of the radiator.
[0012] In one possible implementation, the cooling oil tank is I-shaped, including a first vertical plate box and a second vertical plate box that are parallel and symmetrically distributed, and a connecting vertical plate box that is vertically connected between the first vertical plate box and the second vertical plate box. The connecting vertical plate box is close to the first end of the first vertical plate box. The first vertical plate box and the second vertical plate box are perpendicularly bent and close to each other at the second end. The first end and the second end are opposite ends. The high-temperature oil inlet and the low-temperature oil outlet are respectively located at the top of the ends of the first vertical plate box and the second vertical plate box that are perpendicularly bent and close to each other.
[0013] The inlet of the cooling water passage is close to the first end of the first vertical plate box and located on the outside.

The outlet is located at the first end of the first vertical plate box and located on the inside.
[0014] In one possible implementation, a temperature sensor is provided in the first chamber, the temperature sensor is signal-connected to the main controller of the clearing machine, and an electrically controlled valve is installed in the cooling water passage, the electrically controlled valve is electrically connected to the main controller of the clearing machine.
[0015] Beneficial effects: Compared with the prior art, the water-cooled heat dissipation device for the cleaning machine provided in this application has an additional heat dissipation oil tank and a cooling water passage on the outside of the heat dissipation oil tank. The high-temperature oil in the main oil tank flows to the heat dissipation oil tank, where it exchanges heat with the cooling water passage and becomes low-temperature oil. Then, it flows back to the second chamber of the main oil tank from the low-temperature oil outlet of the heat dissipation oil tank for use by the various oil-using components of the cleaning machine.

Therefore, the above terms should not be construed as limitations on this utility model.
[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0024] refer to Figures 1 to 4 This application provides a water-cooled heat dissipation device for a cleaning machine, used for cooling the main oil tank 10 of the cleaning machine. The main oil tank 10 is equipped with a partition 11 to divide its inner cavity into a first chamber 101 and a second chamber 102. The first chamber 101 has an oil return port and a high-temperature oil outlet at the bottom, while the second chamber 102 has an oil outlet and a low-temperature oil inlet at the bottom. Thus, the main oil tank 10 supplies oil to the various oil-using devices of the cleaning machine through the oil return port and the oil outlet via a connecting pipeline. In simple terms, a conventional cleaning machine oil tank is designed with two chambers, namely the first chamber and the second chamber 102. The oil inlet and outlet of the conventional cleaning machine oil tank are respectively located in the first chamber 101 and the second chamber 102. Furthermore, the bottom of the first chamber 101 and the second chamber 102 are respectively provided with a high-temperature oil outlet and a low-temperature oil inlet.
[0025] The water-cooled heat dissipation device of the cleaning machine also includes a heat dissipation oil tank 20. The heat dissipation oil tank 20 is located below the main oil tank 10. The heat dissipation oil tank 20 is provided with a high-temperature oil inlet 201 and a low-temperature oil outlet 202. The high-temperature oil inlet 201 is connected to the high-temperature oil outlet through a first pipe. The low-temperature oil outlet 202 is connected to the low-temperature oil inlet through a second pipe. A cooling water passage 30 is provided on the outside of the heat dissipation oil tank 20. The inlet 301 of the cooling water passage 30 is connected to external water. The outlet 302 of the cooling water passage 30 is provided at the end away from the inlet 301 in the passage direction, so as to cool the heat dissipation oil tank 20 by water-cooling heat exchange.
[0026] Therefore, the water-cooled heat dissipation device for the cleaning machine provided in this application uses an additional heat dissipation oil tank and a cooling water passage 30 designed on the outside of the heat dissipation oil tank 20. At the same time, the main oil tank 10 is set as a first chamber 101 and a second chamber 102 that are separated from each other. The high-temperature oil generated by each oil-using component on the cleaning machine flows into the heat dissipation oil tank 20 through the first chamber 101. In the heat dissipation oil tank 20, it undergoes heat exchange with the cooling water passage 30 and becomes low-temperature oil, which then flows back to the second chamber 102. Finally, the cooled low-temperature oil is supplied to each oil-using component. It can effectively cool each oil-using component by means of water cooling, with high cooling efficiency, and does not occupy the limited space near the main oil tank, so as not to affect the normal operation of the surrounding equipment.
[0027] Considering that there is a large usable space at the track chassis 40 of the warehousing machine, and that it is located below the main oil tank 10, preferably, the cooling oil tank 20 is fixed at the track chassis 40 of the warehousing machine, for example, directly above the track chassis 40 and close to the middle position.
[0028] In one embodiment, the partition 11 is a multi-layered partition with parallel distribution, such as a two-layered or three-layered partition, and there are heat insulation gaps, or heat insulation spaces, between adjacent partitions of the multi-layered partition, which can reduce the heat exchange between hydraulic oils of different temperatures between the first chamber 101 and the second chamber 102, resulting in a better cooling effect.
[0029] In one embodiment, the heat exchange tank 20 is a frame structure, and the cooling water passage 30 is integrated and arranged on the surface of the heat exchange tank 20, thereby increasing the contact area between the heat exchange tank 20 and the cooling water passage 30 and improving the heat exchange effect.
[0030] More preferably, the heat dissipation oil tank 20 is I-shaped, including a first vertical plate box 21 and a second vertical plate box 22 that are parallel and symmetrically distributed, and a connecting vertical plate box 23 that is vertically connected between the first vertical plate box 21 and the second vertical plate box 22. The connecting vertical plate box 23 is close to the first end 211 of the first vertical plate box 21. The first vertical plate box 21 and the second vertical plate box 22 are perpendicularly bent and close to each other at the second end 212. The first end 211 and the second end 212 are opposite ends. At the same time, the high-temperature oil inlet 201 and the low-temperature oil outlet 202 are respectively located at the top of the ends of the first vertical plate box 21 and the second vertical plate box 22 that are perpendicularly bent and close to each other. This allows the high-temperature oil flowing from the first chamber 101 to flow through a longer path in the heat dissipation oil tank 20 to facilitate sufficient heat exchange.
[0031] The inlet 301 of the cooling water passage 30 is close to the first end 211 of the first vertical plate box 21 and located on the outside. At the same time, the cooling water passage 30 extends sequentially along the outside of the first vertical plate box 21, the inside of the first vertical plate box 21, the side of the connecting vertical plate box 23 near the second end 212, the inside of the second vertical plate box 22, the outside of the second vertical plate box 22, the side of the connecting vertical plate box 23 near the first end 211, and the inside of the first vertical plate box 21. The outlet 302 is located at the first end 211 of the first vertical plate box 21 and is located on the inside. Thus, the cooling water can basically cover the entire outer surface of the radiator oil tank, resulting in better heat exchange.
[0032] In one embodiment, a temperature sensor is provided in the first chamber 101, and the temperature sensor is signal-connected to the main controller of the cleaning machine. At the same time, an electrically controlled valve is installed in the cooling water passage 30, and the electrically controlled valve is electrically connected to the main controller of the cleaning machine. This allows the cleaning machine to operate without cooling in the early stages. Only when the temperature of the hydraulic oil in the first chamber 101 is high will the electrically controlled valve be automatically opened by the main controller of the cleaning machine to allow cooling water to flow in for heat exchange. This can save resources and reduce costs to a certain extent.
[0033] It should be noted that the terms "first" and "second" used in this application are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
