Technical Field

[0001] The utility model relates to the technical field of grinding fluid filtering equipment, in particular to a centrifugal filtering device for grinding fluid. Background Technique

[0002] The grinding and polishing agent, that is, the grinding fluid, is composed of aviation gasoline, kerosene, transformer oil, various vegetable oils, animal oils and hydrocarbons, and is mixed with several additives. It is widely applicable to the grinding and polishing of hard materials such as superhard materials and cemented carbide for electronic products. It can not only improve the grinding rate, but also quickly discharge a large amount of heat generated during the grinding process, thereby avoiding the workpiece surface from being burned. After the grinding fluid is used, the iron filings and residues in it need to be filtered out, so a filtering device is required.

[0003] When using a centrifugal device to filter the grinding fluid, a large amount of iron filings and residues will remain in the centrifugal cylinder after filtration. Therefore, the centrifugal cylinder needs to be cleaned every time after filtration and after a certain period of filtration. At present, mainly the centrifugal cylinder is manually removed from the filtering device and then taken out for cleaning. The operation is relatively cumbersome and the labor of personnel is large. Therefore, a centrifugal filtering device for grinding fluid is urgently needed to be developed. Content of the Utility Model

Two groups of limiting components are arranged on the inner wall of the housing 1. A centrifugal cylinder 3 is rotatably arranged between the two groups of limiting components. A plurality of slag discharge holes 3-1 are opened at the bottom of the centrifugal cylinder 3. A motor 2 is arranged at the bottom of the inner cavity of the housing 1. The output end of the motor 2 is connected to the central position at the bottom of the centrifugal cylinder 3.

The bottom of the connecting rod 6 is provided with a bottom plate 7. The bottom plate 7 is vertically slidably arranged in the centrifugal cylinder 3. A pair of limiting grooves 7-1 are opened on the bottom plate 7. A pair of limiting strips 4 are vertically arranged on the inner wall of the centrifugal cylinder 3. The limiting strips 4 are slidably arranged in the limiting grooves 7-1. A water inlet pipe 8 is communicatively connected to the top wall of the housing 1. A plurality of spray heads 9 are arranged on the water inlet pipe 8; Each group of limiting components includes a plurality of fixing rods 10 and a limiting ring 11. One end of the fixing rod 10 is arranged on the inner wall of the housing 1, and the other end is connected to the limiting ring 11. A groove is opened on the limiting ring 11. The centrifugal cylinder 3 is rotatably arranged in the grooves on a pair of limiting rings 11; A connecting block 13 is arranged at the top of the connecting rod 6. An installation groove is opened on the connecting block 13. A bearing 14 is arranged in the installation groove. The inner ring of the bearing 14 is connected to the telescopic end of the electric telescopic rod 5; The plurality of spray heads 9 are inclined and communicatively arranged on the water inlet pipe 8; An inclined plate 12 is arranged at the bottom of the inner cavity of the housing 1. A waterproof cover 2-1 is arranged on the inclined plate 12. The motor 2 is arranged on the inclined plate 12 and located inside the waterproof cover 2-1. The liquid outlet pipe 1-2 is arranged at the bottom of the housing 1 and on one side of the bottom end of the inclined plate 12; A limiting block 15 is arranged at the top of each limiting strip 4.

[0021] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] In this utility model, both the motor 2 and the electric telescopic rod 5 are connected to an external electric control system through wires. The above devices and connection methods are all existing technologies and will not be elaborated here.

[0023] According to the attached drawings of the specification Figures 1-4 It can be seen that when this utility model is in use, first, the grinding liquid to be filtered is conveyed into the centrifugal cylinder 3 through the liquid inlet pipe 1-1 connected to the top of the housing 1 (the liquid inlet pipe 1-1 is vertically arranged above the centrifugal cylinder 3). The motor 2 arranged at the bottom of the housing 1 is started (the motor 2 can be arranged at the bottom inner cavity or the bottom outer wall of the housing 1). The output end of the motor 2 drives the connected centrifugal cylinder 3 to rotate. Since a pair of limiting strips 4 on the inner wall of the centrifugal cylinder 3 are embedded into a pair of limiting grooves 7-1 opened on the bottom plate 7, the center position above the bottom plate 7 is connected to the connecting rod 6, and the connecting rod 6 is rotationally connected to the telescopic end of the electric telescopic rod 5. Therefore, when the centrifugal cylinder 3 rotates, it can drive the bottom plate 7 to rotate together. Under the action of centrifugal force, the grinding liquid is filtered outside the centrifugal cylinder 3 and flows out through the liquid outlet pipe 1-2. The iron filings and residues are retained on the bottom plate 7 and the centrifugal cylinder 3. When the centrifugal cylinder 3 needs to be cleaned after filtering for a period of time, the electric telescopic rod 5 is started, so that the telescopic end of the electric telescopic rod 5 drives the rotationally connected connecting rod 6 to move vertically upward. The connecting rod 6 drives the connected bottom plate 7 to move vertically upward, so that the bottom plate 7 moves to the top of the centrifugal cylinder 3. The bottom plate 7 drives the iron filings and residues on it to move together. Then, clean water with a certain pressure is injected into the water inlet pipe 8 through an external water supply device. The clean water is sprayed onto the centrifugal cylinder 3 and the bottom plate 7 through a plurality of spray heads 9 communicated with the water inlet pipe 8. At this time, the motor 2 continues to drive the centrifugal cylinder 3 and the bottom plate 7 to rotate, and the clean water flushes the impurities on the bottom plate 7 and the centrifugal cylinder 3. The flushed impurities are then discharged through the liquid outlet pipe 1-2 (the impurities on the centrifugal cylinder 3 are discharged into the bottom inner cavity of the housing 1 through a plurality of slag discharge holes 3-1 opened at the bottom of the centrifugal cylinder 3 and then discharged from the liquid outlet pipe 1-2); this utility model drives the bottom plate 7 to move to the top of the centrifugal cylinder 3 through the electric telescopic rod 5, the bottom plate 7 drives the impurities in the centrifugal cylinder 3 to move together, and the motor 2 drives the centrifugal cylinder 3 and the bottom plate 7 to rotate, so that the clean water sprayed from a plurality of spray heads 9 is sprayed onto the centrifugal cylinder 3 and the bottom plate 7 to flush the centrifugal cylinder 3 and the bottom plate 7, without manual operation, saving the time for personnel to clean, and the personnel are time-saving and labor-saving.

[0024] There is a possible implementation, each group of limiting components includes multiple fixed rods 10 and limiting rings 11, one end of the fixed rod 10 is set on the inner wall of the shell 1, and the other end is connected to the limiting ring 11, the limiting ring 11 is provided with a groove, a pair of grooves on a pair of limiting rings 11 are relatively opened, the centrifuge cylinder 3 is rotatably set in the grooves on a pair of limiting rings 11, multiple fixed rods 10 fix the limiting rings 11, and two limiting rings 11 limit and fix the centrifuge cylinder 3 to prevent the centrifuge cylinder 3 from shaking when rotating.

[0025] There is a possible implementation, a connecting block 13 is provided on the top of the connecting rod 6, a mounting groove is opened on the connecting block 13, a bearing 14 is provided in the mounting groove, the inner ring of the bearing 14 is connected to the telescopic end of the electric telescopic rod 5, and the outer ring of the bearing 14 is connected to the side wall of the mounting groove, so that when the bottom plate 7 drives the connecting rod 6 to rotate, the electric telescopic rod 5 does not rotate.

[0026] There is a possible implementation in which a plurality of nozzles 9 are arranged obliquely and connected on the water inlet pipe 8 so that when the nozzles 9 flush the bottom plate 7 , the clean water sprayed from the nozzles 9 can be sprayed onto the bottom plate 7 to flush the iron filings and residues on the bottom plate 7 .
