Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic systems, in particular to a hydraulic oil filter for a cone crusher. Background Art

[0002] Cone crushers are usually used to crush and process various hard and medium-hard ores and rocks. In the working process of cone crushers, the hydraulic system plays an important role, responsible for providing power and control functions to ensure the stable operation and efficient production of the equipment. The hydraulic oil filter, as a key component in the hydraulic system, affects the cleanliness of the hydraulic oil and the reliability of the system.

[0003] The hydraulic oil filter of a traditional cone crusher usually consists of a filter cartridge, which is designed to be positioned in the hydraulic system to capture the oil flowing through it. When the hydraulic oil passes through the filter cartridge, solid particles and dirt are trapped by the mesh or pores on the filter cartridge, while the clean hydraulic oil passes through the filter cartridge into the hydraulic system;

[0004] The hydraulic oil filter of the traditional cone crusher has the following problems: since it can only be filtered in one filter cartridge, this limits its filtering effect, and the filter cartridge cannot be self-cleaned during the filtering process, resulting in impurities deposited on the surface of the filter cartridge being difficult to effectively remove, affecting the durability and filtering efficiency of the filter. For this reason, we propose a hydraulic oil filter for a cone crusher. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydraulic oil filter for a cone crusher, comprising a filter barrel and a filter mechanism;

[0007] Filter barrel: A mounting seat is fixedly connected to the lower end of the inner wall, a sealing groove is provided on the upper surface of the mounting seat, and a large-diameter filter cartridge is provided on the inner wall of the sealing groove;

[0008] Filtering mechanism: It includes a small-diameter filter cartridge, a fixed disk, a socket and a rotating shaft. The rotating shaft is rotatably connected to the top wall of the filter barrel. The bottom end of the rotating shaft is fixedly connected to the fixed disk. The upper surface of the fixed disk is provided with evenly distributed sockets. The inner walls of the sockets are fixedly connected with small-diameter filter cartridges. The small-diameter filter cartridges are located inside the large-diameter filter cartridge, which can ensure that the hydraulic oil reaches the required cleanliness, effectively prevent large particles and tiny impurities from entering the system, and improve the filtering effect. At the same time, it can realize self-cleaning of the filter cartridge, effectively remove impurities deposited on the surface of the filter cartridge, and improve the durability of the filter.

[0009] Furthermore, it also includes a single-chip microcomputer, which is arranged at the front end of the outer surface of the filter barrel, and the input end of the single-chip microcomputer is electrically connected to an external power supply to facilitate the regulation of the operation of various electrical appliances.

[0010] Furthermore, a liquid inlet pipe is fixedly connected to the liquid inlet at the right end of the outer surface of the filter barrel, and a liquid outlet pipe is fixedly connected to the liquid outlet at the bottom end of the filter barrel to provide the inlet and outlet of the hydraulic oil.

[0011] Furthermore, it also includes a sewage pipe, which is fixedly connected to the sewage outlet at the front end of the outer surface of the filter barrel to facilitate the discharge of impurities.

[0012] Furthermore, the filtering mechanism also includes a rotating shaft and a scraper. There are four rotating shafts, which are rotatably connected to the lower surface of the fixed plate respectively. The lower ends of the rotating shafts are fixedly connected to scrapers, which are installed in cooperation with the outer surface of a large-diameter filter cartridge to prevent impurity accumulation and a decrease in filtration efficiency.

[0013] Furthermore, the filtering mechanism also includes gears and gear rings, the gear rings are fixedly connected to the upper end of the inner wall of the filtering barrel, the gears are respectively fixedly sleeved on the upper ends of four rotating shafts, and the gears are all meshed and connected with a gear ring to achieve self-rotation.

[0014] Furthermore, the filtering mechanism also includes a motor, which is installed on the upper surface of the filtering barrel by bolts, the bottom end of the output shaft of the motor is fixedly connected to the top end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the single-chip microcomputer to drive the filtering mechanism to operate.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the hydraulic oil filter of the cone crusher has the following advantages:

[0016] 1. The hydraulic oil will pass through the large-diameter filter cartridge, which mainly blocks large particles of impurities, such as metal chips, large particles of dust, etc., to prevent them from entering the subsequent more sophisticated filtering mechanism. The large particles of impurities are blocked outside the large-diameter filter cartridge by the large-diameter filter cartridge, while smaller impurities are captured as the hydraulic oil passes through the filter element holes on the large-diameter filter cartridge. After the hydraulic oil is filtered by the large-diameter filter cartridge, it enters the large-diameter filter cartridge. At this time, the motor operation is controlled by the single-chip microcomputer. The rotation of the motor's output shaft drives the rotation of the rotating shaft, and the rotating shaft drives the fixed disk and the small-diameter filter cartridge on the fixed disk to rotate, so as to ensure that the hydraulic oil is filtered multiple times between the large-diameter filter cartridge and the small-diameter filter cartridge, to ensure that the oil reaches the required cleanliness, and to improve the filtering effect of the hydraulic oil filter of the cone crusher.

[0017] 2. When the fixed plate rotates, it will drive the shaft and the scraper to start orbiting around the shaft, so that the scraper contacts the outer surface of the small-diameter filter cartridge. However, the scraper can cover most of the outer surface of the large-diameter filter cartridge during the orbital process, effectively removing particles and dirt attached to the surface of the large-diameter filter cartridge. At the same time, the rotation of the shaft will drive the gear to mesh with the gear ring, causing the gear to rotate. The gear drives the shaft to rotate, thereby driving the scraper to start self-rotation. Through the continuous rotation of the scraper, the tiny impurities and particles on the surface of the large-diameter filter cartridge can be more thoroughly removed. Therefore, by combining the orbital and self-rotation, the scraper can more effectively cover and clean the entire surface of the large-diameter filter cartridge to prevent sediment accumulation, thereby increasing the service life of the hydraulic oil filter of the cone crusher.

The large-diameter filter cartridge 6 mainly blocks large particles of impurities, such as metal chips, large particles of dust, etc., to prevent them from entering the subsequent more refined filtering mechanism 5. The large particles of impurities are blocked outside the large-diameter filter cartridge 6 by the large-diameter filter cartridge 6, while smaller impurities are captured as the hydraulic oil passes through the filter element pores on the large-diameter filter cartridge 6. After the hydraulic oil is filtered by the large-diameter filter cartridge 6, it enters the large-diameter filter cartridge, which also includes The single chip microcomputer 2 is provided at the front end of the outer surface of the filter barrel 1, and the input end of the single chip microcomputer 2 is electrically connected to the external power supply. The liquid inlet at the right end of the outer surface of the filter barrel 1 is fixedly connected with a liquid inlet pipe 4, and the hydraulic oil enters the filter barrel 1 through the connected liquid inlet pipe 4. The liquid outlet at the bottom end of the filter barrel 1 is fixedly connected with a liquid outlet pipe 3, and the liquid outlet pipe 3 is connected to the external hydraulic system. It also includes a sewage pipe 9, which is fixedly connected to the sewage outlet at the front end of the outer surface of the filter barrel 1. The tiny impurities and large particle impurities removed by the scraper 57 are discharged from the outside of the large-diameter filter cartridge 6 through the sewage pipe 9, ensuring that only clean hydraulic oil flows in the hydraulic system;

[0027] The filter mechanism 5 includes a small-diameter filter cartridge 52, a fixed disk 53, a socket 54 and a rotating shaft 59. The rotating shaft 59 is rotatably connected to the top wall of the filter barrel 1. The bottom end of the rotating shaft 59 is fixedly connected to the fixed disk 53. The upper surface of the fixed disk 53 is provided with evenly distributed sockets 54. The inner walls of the sockets 54 are fixedly connected to the small-diameter filter cartridges 52. The small-diameter filter cartridges 52 are all located inside the large-diameter filter cartridge 6. The filter mechanism 5 also includes a rotating shaft 55 and a scraper 57. There are four rotating shafts 55. The four rotating shafts 55 are respectively rotatably connected to the lower surface of the fixed disk 53. The lower ends of the rotating shafts 55 are fixedly connected to the filter cartridge 6. There are scrapers 57, and the scrapers 57 are mounted on the outer surface of a large-diameter filter cartridge 6. The filtering mechanism 5 also includes a gear 56 and a gear ring 58. The gear ring 58 is fixedly connected to the upper end of the inner wall of the filter barrel 1. The gears 56 are respectively fixedly sleeved on the upper ends of the four rotating shafts 55. The gears 56 are meshed with a gear ring 58. The filtering mechanism 5 also includes a motor 51. The motor 51 is installed on the upper surface of the filter barrel 1 by bolts. The bottom end of the output shaft of the motor 51 is fixedly connected to the top end of the rotating shaft 59. The input end of the motor 51 is electrically connected to the output end of the single-chip microcomputer 2. The operation of the motor 51 is regulated by the single-chip microcomputer 2. The output shaft of the motor 51 rotates to drive the rotating shaft 59 to rotate, and the rotating shaft 59 drives the fixed disk 53 and the small-diameter filter cartridge 52 on the fixed disk 53 to rotate, so as to ensure that the hydraulic oil is filtered multiple times between the large-diameter filter cartridge 6 and the small-diameter filter cartridge 52 to ensure that the oil reaches the required cleanliness. After the hydraulic oil is filtered by the large-diameter filter cartridge 6 and the small-diameter filter cartridge 52, it flows smoothly to the outlet pipe 3 by gravity and enters the hydraulic system. When the fixed disk 53 rotates, it drives the rotating shaft 55 and the scraper 57 to start orbiting around the rotating shaft 59, so that the scraper 57 contacts the outer surface of the small-diameter filter cartridge 52, but the scraper 5 During the revolution, most of the outer surface of the large-diameter filter cartridge 6 can be covered, and particles and dirt attached to the surface of the large-diameter filter cartridge 6 can be effectively removed. At the same time, the rotation of the rotating shaft 55 will drive the gear 56 to mesh with the gear ring 58, so that the gear 56 rotates, and the gear 56 drives the rotating shaft 55 to rotate, thereby driving the scraper 57 to start self-rotation. Through the continuous rotation of the scraper 57, the tiny impurities and particles on the surface of the large-diameter filter cartridge 6 can be more thoroughly removed. Therefore, through the combination of revolution and self-rotation, the scraper 57 can more effectively clean the surface of the large-diameter filter cartridge 6 to prevent impurities from accumulating and the filtration efficiency from decreasing.

[0028] The working principle of a hydraulic oil filter for a cone crusher provided by the utility model is as follows: first, the liquid outlet pipe 3 is connected to the external hydraulic system, and then the hydraulic oil enters the filter barrel 1 through the connected liquid inlet pipe 4. Before entering the filtering mechanism 5, the hydraulic oil will pass through the large-diameter filter cartridge 6. The large-diameter filter cartridge 6 mainly blocks large particles of impurities, such as metal chips, large particles of dust, etc., to prevent them from entering the subsequent more refined filtering mechanism 5. The large particles of impurities are blocked on the outside of the large-diameter filter cartridge 6 by the large-diameter filter cartridge 6, while smaller impurities are captured as the hydraulic oil passes through the filter element pores on the large-diameter filter cartridge 6. After the hydraulic oil is filtered by the large-diameter filter cartridge 6, it enters the inside of the large-diameter filter cartridge. At this time, the operation of the motor 51 is controlled by the single-chip microcomputer 2. The rotation of the output shaft of the motor 51 drives the rotating shaft 59 to rotate. The rotating shaft 59 drives the fixed disk 53 and the small-diameter filter cartridge 52 on the fixed disk 53 to rotate, so as to ensure that the hydraulic oil is filtered multiple times between the large-diameter filter cartridge 6 and the small-diameter filter cartridge 52 to ensure that the oil reaches the required cleanliness. When the hydraulic oil passes through the large-diameter filter cartridge 6 and the small-diameter filter cartridge 52, the hydraulic oil is filtered by the large-diameter filter cartridge 6 and the small-diameter filter cartridge 52. After the filter cartridge 52 of the small diameter has finished filtering, it flows smoothly to the liquid outlet pipe 3 by gravity and enters the hydraulic system. When the fixed plate 53 rotates, it drives the rotating shaft 55 and the scraper 57 to start orbiting around the rotating shaft 59, so that the scraper 57 contacts the outer surface of the small diameter filter cartridge 52. However, the scraper 57 can cover most of the outer surface of the large diameter filter cartridge 6 during the orbital process, effectively removing the particles and dirt attached to the surface of the large diameter filter cartridge 6. At the same time, the rotation of the rotating shaft 55 drives the gear 56 to mesh with the gear ring 58, so that the gear 56 rotates. The gear 56 drives the rotating shaft 55 to rotate, thereby driving the scraper 57 to start self-rotation, and the continuous rotation of the scraper 57 can more thoroughly remove the tiny impurities and particles on the surface of the large-diameter filter cartridge 6. Therefore, through the combination of revolution and rotation, the scraper 57 can more effectively clean the surface of the large-diameter filter cartridge 6 to prevent the accumulation of impurities and the decrease of filtering efficiency. Then, the tiny impurities and large particles of impurities removed by the scraper 57 are discharged from the outside of the large-diameter filter cartridge 6 through the drain pipe 9, ensuring that only clean hydraulic oil flows in the hydraulic system.
