Description

Technical Field

[0001] The present disclosure relates to the technical field of cooling equipment, and in particular to a crusher cooling system. Background Art

[0002] The crusher automatic control system has multiple protection functions. In summer, the oil temperature in the lubrication system often rises due to poor cooling effect of the lubricating oil. When the oil temperature rises to 50°C, it reaches the alarm threshold set by the crusher automatic control system. When the oil temperature rises to 55°C, in order to protect the internal components of the crusher from damage, the automatic control system stops the equipment. The crusher needs to be stopped and the oil temperature must be lowered before it can be started again for crushing operations, which seriously affects the continuity of the crushing operation.

[0003] In the related art, a cooling fan is used to cool the lubricating oil. Since the oil tank is set below the crusher, the crushed dust is very easy to adhere to the heat sink, and the space where the fan is located is narrow and the airflow is not smooth. In addition, air cooling is greatly affected by the environment. The room temperature in summer is about 25℃, which is not conducive to cooling on site. Summary of the invention

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the directional terms "upper" and "lower" are defined based on the actual directions in which the relevant components are used. "Inside" and "outside" refer to the contours of the corresponding components. In the present disclosure, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] Reference Figure 1 The present disclosure provides a crusher cooling system, which may include a crusher 1, an oil tank 2, and an oil inlet pipe 3 and an oil return pipe 4 connected between the crusher 1 and the oil tank 2. When the crusher 1 is performing a crushing operation, heat is generated inside the body. The gear oil pump pumps the lubricating oil in the oil tank 2 into the oil inlet pipe 3 and then into the crusher 1 for lubrication and cooling. The return oil flows into the oil tank 2 through the oil return pipe 4 to realize the circulation of the lubricating oil. The oil inlet pipe 3 and the oil return pipe 4 or one of the oil inlet pipe 3 and the oil return pipe 4 is connected with a cooling device 5. The cooling device 5 may include a shell, the shell forms a receiving cavity, and the receiving cavity is provided with a coolant pipe 51 for loading cooling water. The cooling device 5 may be configured so that the oil entering the oil inlet pipe 3 and / or the oil return pipe 4 flows out through the receiving cavity. The crusher mentioned above may be a cone crusher.

[0029] Through the above technical solution, the lubricating oil passes through the cooling device during the circulation process, and the lubricating oil passing through the accommodating chamber is cooled by the coolant in the coolant pipe. The cooling effect of the crusher cooling system is good and is not affected by the external environment, so as to ensure the continuity of the crushing operation.

[0030] Further, refer to Figure 1 The cooling liquid pipe 51 can be bent to form a plurality of pipe sections arranged side by side. Bending the cooling liquid pipe 51 to form a heat exchange area can increase the cooling effect of the lubricating oil passing through the accommodating cavity.

[0031] In some embodiments, reference Figure 1 The coolant pipe 51 has a liquid inlet end and a liquid outlet end extending out of the housing respectively. The liquid inlet end can be connected to a water source through a pipeline pump 6. The water source can be underground water. The pipeline pump 6 pumps the underground production water with a lower temperature into the coolant pipe 51. The coolant pipe 51 is built inside the housing of the cooling device 5 to cool the lubricating oil passing through the cooling device 5. The pipeline pump 6 can increase the water flow rate and improve the heat exchange efficiency. Furthermore, the liquid outlet end can be connected to a washing nozzle 7. Usually, a ore dressing plant is provided with a manual rough stone selection platform on the coarse crushing feeding belt (rough stone refers to waste stone that does not contain target gold. Removing rough stone can reduce crushing energy consumption and improve recovery rate). The clean ore is conducive to the employees' selection of rough stone. There will be sticky ore mud on the surface of the ore. The ore must be washed before the coarse crushing operation. The water discharged through the coolant pipe 51 can be used to wash the ore on the jaw crusher feeding belt. The water pressurized by the washing nozzle 7 is more conducive to washing the sticky ore mud on the surface of the ore.

[0032] The coolant pipe 51 may be made of copper or other metal materials, such as galvanized pipe, stainless steel pipe, aluminum alloy pipe, carbon steel pipe, etc. The coolant pipe 51 made of metal has strong corrosion resistance and wear resistance.

[0033] In the embodiments of the present disclosure, reference Figure 1 The cooling device 5 can be connected to the oil return pipe 4. The lubricating oil returned from the crusher 1 enters the cooling device 5 through the oil return pipe 4. After cooling, it enters the oil tank 2 through the oil return pipe 4 to cool the lubricating oil during the oil return stage.

[0034] As an exemplary embodiment of the present disclosure, refer to Figure 1 The outer cover of the oil tank 2 may be provided with a closed box 8, and a closed cavity is formed between the inner wall of the closed box 8 and the outer wall of the oil tank 2. The closed box 8 is arranged outside the oil tank 2 to isolate the oil tank 2 from the external room temperature, so that the temperature of the oil tank 2 is not disturbed by the external temperature.

[0035] Further, the closed box 8 may have a water inlet for injecting cold water into the closed chamber. In the summer when the temperature is high, cold water may be injected into the closed chamber to cool the lubricating oil in the oil tank 2.

[0036] In winter when the temperature is low, the lubricating oil will become viscous and have poor fluidity. Therefore, in the related art, the lubricating oil in the oil tank 2 must be heated to 20°C by a heater before the equipment is started each time. The entire heating process lasts about 25 minutes. In order not to affect the continuity of the crushing, in the embodiment of the present disclosure, the reference Figure 1 The closed box 8 may have an inlet 81 for inputting steam into the closed chamber, and an outlet 82 for discharging steam water. The steam for workshop heating may be introduced into the closed chamber from the inlet 81 to keep warm and preheat the lubricating oil in the oil tank 2, and the steam water formed after cooling may be discharged from the closed chamber through the outlet 82. In the above manner, the oil tank 2 may be heated at a low temperature, so as to avoid the lubricating oil becoming viscous and having poor fluidity at a low temperature, thereby affecting the operation of the crusher 1, and the steam used for workshop heating may be used to reuse heating resources.

[0037] In some embodiments, reference Figure 1 An air cooler 9 can be installed above the oil tank 2, and air is blown to the heat sink of the oil tank 2 through the air cooler 9, further enhancing the heat dissipation effect.

[0038] According to some embodiments, a temperature detector may be provided in the oil tank 2, and the temperature detector may be communicatively connected to the pipeline pump 6, and may also be communicatively connected to all valves of the crusher cooling system, so that when the temperature reaches an alarm threshold, the valve may be opened to cool or heat the lubricating oil.

[0039] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0041] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
