Description

Technical Field

[0001] The utility model belongs to the technical field of cooling equipment, and particularly relates to an efficient cooling mechanism for a ball mill journal bearing. Background Art

[0002] A journal bearing is the part that contacts the journal of a sliding bearing, with a semi-cylindrical surface in the shape of a tile, which is very smooth. It is generally made of wear-resistant materials such as bronze and antifriction alloys. In special cases, it can be made of wood, engineering plastics or rubber. There are two types of journal bearings: integral and split. Integral journal bearings are usually called bushings. Integral journal bearings can be either without oil grooves or with oil grooves. The journal bearing and the journal adopt a clearance fit and generally do not rotate with the shaft.

[0003] The journal bearing oil of a ball mill plays a crucial role in the operation of the ball mill, and its main functions are reflected in the following aspects; Lubrication function: The journal bearing oil forms a lubricating film in the ball mill, effectively preventing direct contact between parts such as the journal bearing and the hub, thereby reducing friction and wear and protecting these key components; Reducing noise and vibration: Good lubrication can significantly reduce the noise and vibration during the operation of the ball mill, improving the operation stability and comfort of the equipment; Improving operation stability: The use of journal bearing oil helps to maintain the stability of the ball mill speed, reducing performance fluctuations caused by friction and wear, thereby improving the overall operation stability of the equipment; Reducing power consumption: When the lubrication effect is good, the journal bearing oil can significantly reduce the frictional resistance of the bearing, enabling the ball mill to consume less power during operation and improving energy utilization efficiency; Reducing the working temperature: High-quality journal bearing oil can effectively reduce the frictional heat during the operation of the bearing, reducing energy loss, thereby reducing the working temperature of the equipment and extending the service life of the equipment.

[0004] However, the existing technology lacks equipment for cooling and reducing the temperature of the cooling oil in the journal bearing oil station, which will cause the journal bearing oil to always remain at a high temperature during operation, having a certain impact on the normal and efficient operation of the ball mill equipment. Content of the Utility Model

A temperature reduction member for cooling the coolant is installed on one side of the cooling tank close to the cooling pipeline.

A liquid pump is installed on the liquid return pipe, and a condenser is installed between the liquid extraction pipe and the liquid return pipe.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The pump body of the present utility model extracts the high-temperature cooling oil in the bearing bush oil station through the oil extraction pipe, so that the high-temperature cooling oil enters the cooling pipeline.

[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Embodiment 1

[0023] As shown in Figure 1 , Figure 2 and Figure 3 , a high-efficiency cooling mechanism for the bearing of a ball mill includes a bearing oil station 1, a circulating cooling assembly 2 and a filter mechanism 3. The circulating cooling assembly 2 is communicated with the bearing oil station 1. The filter mechanism 3 is arranged inside the circulating cooling assembly 2. The circulating cooling assembly 2 includes a cooling tank 21 filled with coolant inside and an oil suction pipe 22 and an oil return pipe 23 fixedly installed on the cooling tank 21 and communicated with the bearing oil station 1. A pump body 24 is installed on the oil return pipe 23. A cooling pipeline 25 fixedly installed inside the cooling tank 21 and communicated with the ends of the oil suction pipe 22 and the oil return pipe 23 and arranged in a spiral shape is provided. A cooling element 26 for cooling the coolant is installed on one side of the cooling tank 21 close to the cooling pipeline 25.

[0024] It should be noted that the cooling pipeline 25 arranged in a spiral shape is immersed in the coolant, which can effectively increase the contact area with the coolant, thereby improving the cooling effect.

[0025] Specifically, when the pump body 24 is started, the pump body 24 pumps out the high-temperature cooling oil in the bearing oil station 1 through the oil suction pipe 22, so that the high-temperature cooling oil enters the cooling pipeline 25. The cooling pipeline 25 is immersed in the coolant in the cooling tank 21 to cool the high-temperature cooling oil. The cooled cooling oil enters the bearing oil station 1 again through the oil return pipe 23. In this way, the cooling oil is cooled cyclically, which can effectively ensure the lubrication and cooling effects of the cooling oil and improve the service life of the equipment.

[0026] As shown in Figure 1 and Figure 2As shown, the temperature reduction component 26 includes a liquid extraction pipe 261 and a liquid return pipe 262 fixedly installed on the cooling tank 21. A liquid pump 263 is installed on the liquid return pipe 262, and a condenser 264 is installed between the liquid extraction pipe 261 and the liquid return pipe 262.

[0027] Specifically, start the liquid pump 263, extract the coolant in the cooling tank 21 through the liquid extraction pipe 261 and send it into the condenser 264 for temperature reduction, and then send it back into the cooling tank 21 through the liquid return pipe 262. In this way, the coolant is cooled in a cycle, thereby completing the temperature reduction of the cooling oil in the cooling pipeline 25, which is efficient and reliable.

[0028] As Figure 1 and Figure 2 shown, a valve 27 is installed on the oil extraction pipe 22.

[0029] Specifically, open the valve 27 to ensure that the cooling oil flows into the cooling tank 21 for temperature reduction. When the cooling tank 21 needs to be maintained, close the valve 27 so that the cooling oil stays in the bearing oil station 1 to avoid waste of the outflow of the cooling oil.

[0030] Embodiment 2

[0031] As Figure 1 , Figure 2 and Figure 3 shown, a high-efficiency cooling mechanism for the bearing of a ball mill. Compared with Embodiment 1, the filtering mechanism 3 of this embodiment includes a material receiving funnel 31 fixedly installed at the feed end of the cooling pipeline 25 and a filtering cylinder 32 lapped on the material receiving funnel 31. The material receiving funnel 31 is adapted to the inner side wall of the cooling tank 21, and a filter screen 33 is fixedly installed on the inner wall of the filtering cylinder 32.

[0032] It should be noted that the material receiving funnel 31 and the filtering cylinder 32 are designed in a split manner, which is convenient to take out the filtering cylinder 32 and clean the metal debris on the filter screen 33, which is convenient and fast.

[0033] Specifically, the pump body 24 pumps the cooling oil into the cooling tank 21 through the oil extraction pipe 22. The cooling oil will first enter the filtering cylinder 32. Affected by the suction of the pump body 24, the cooling oil will pass through the filter screen 33 and enter the material receiving funnel 31 and finally enter the cooling pipeline 25 for cooling circulation. When passing through the filter screen 33, the metal debris will be filtered and retained on the filter screen 33, ensuring the cleanliness of the cooling oil, ensuring the cooling efficiency, and reducing the wear on the shaft body.

[0034] As Figure 2 and Figure 3 shown, a docking ring 34 adapted to the top opening of the material receiving funnel 31 is fixedly installed at one end of the filtering cylinder 32 opposite to the material receiving funnel 31, and a sealing ring 35 is sleeved on the outer side wall of the docking ring 34.

[0035] Specifically, the end of the filter cartridge 32 with the docking ring 34 is set downward, so that the filter cartridge 32 extends into the cooling tank 21 and is engaged with the inner side of the top of the material receiving funnel 31. The sealing ring 35 is pressed at the docking port for sealing, so as to prevent the cooling oil from leaking out and contaminating the inner wall of the cooling tank 21 during filtration, making it cleaner and tidier.

[0036] As Figure 2 and Figure 3 shown, a support ring 36 adapted to the material receiving funnel 31 is fixedly installed on the inner side wall of the cooling tank 21.

[0037] Specifically, the material receiving funnel 31 with the cooling pipeline 25 connected below is lapped on the support ring 36, thereby improving the stability of the material receiving funnel 31.

[0038] As Figure 2 and Figure 3 shown, a diversion pipe 37 extending to the center position above the filter cartridge 32 is screwed at the interface of the inner side wall of the cooling tank 21 and the oil suction pipe 22.

[0039] During use, the diversion pipe 37 is screwed at the pipe orifice position of the oil suction pipe 22 on the inner wall of the cooling tank 21, so that the end of the diversion pipe 37 away from the oil suction pipe 22 is arranged to face the center of the opening of the filter cartridge 32, which can effectively avoid the problem that the oil liquid falls along the inner part of the cooling tank 21 and immerses into the gap between the filter cartridge 32 and the cooling tank 21. When disassembling and assembling the filter cartridge 32, the diversion pipe 37 can be removed from the inner wall of the cooling tank 21, so as not to affect the disassembly and assembly of the filter cartridge 32, which is very practical.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
