Abstract
Description
Technical Field
[0001] This utility model relates to a filtration device. Background Technology
[0002] During bearing production, such as grinding, the bearing needs to be cleaned with a cleaning fluid. This cleaning fluid then contains grinding debris. To allow the cleaning fluid to be reused, it needs to be filtered. Existing technologies offer various types of filtration devices, each with its own advantages and disadvantages, and all are structurally complex. Summary of the Invention
[0003] In order to overcome the above-mentioned shortcomings in the prior art, this utility model provides a grinding fluid centralized filtration device with a more reasonable structure.
[0004] This utility model is achieved through the following technical solution:
[0005] A grinding fluid centralized filtration device is characterized by: a filter cloth arranged in a circle, the filter cloth being rotated by a rotating roller stretched around the inner surface of the filter cloth; a spraying part pressed on top of the filter cloth, the collected grinding fluid being connected to the spraying part after being pressurized; a receiving plate with mesh openings below the filter cloth; a water receiving pool below the mesh openings; an air outlet device for air outlet to the outside of the filter cloth within the space surrounded by the filter cloth; a material drop box below the outside of the filter cloth; and nozzles on both sides below the filter cloth, the nozzles being connected to the water receiving pool.
[0006] Preferably, the outer side of the filter cloth is arranged sloping inward from top to bottom.
[0007] Preferably, the two ends of the rotating roller are connected to chains via gears, one of the rotating rollers is connected to a motor, the chain is provided with a connecting piece on the side near the filter cloth, the connecting piece is provided with a connecting hole, and the two sides of the filter cloth are tied to the connecting hole of the connecting piece by cable ties.
[0008] Preferably, the filter cloth has edging on both sides, and the nozzle sprays towards the edging.
[0009] The beneficial effects of this utility model are as follows: This application uses a selected rotating filter cloth for filtration, and an air outlet device blows air out onto the outside of the filter cloth to dry it and blow off the residue. The filtered liquid is then used for rinsing, and nozzles further clean both sides. This application has a reasonable structure and is suitable for primary filtration of grinding fluid. Attached Figure Description
[0010] Figure 1 This is a front view structural diagram of the present invention.
[0011] Figure 2 This is a side view of the structure of this utility model. Detailed Implementation
[0012] The utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0013] like Figure 1 As shown in Figure 2, a centralized grinding fluid filtration device includes a filter cloth 7 arranged in a circular pattern. The filter cloth 7 is circulated by rotating rollers 1 stretched around the inner surface of the filter cloth. Both ends of the rotating rollers 1 are connected to chains 2 via gears. One rotating roller 1 is the driving rotating roller, which is connected to a motor 13, thus driving the other rotating rollers to rotate, achieving the circulated rotation of the filter cloth. A connecting piece 3 is provided on the side of the chain near the filter cloth, and the connecting piece has connecting holes. The two sides of the filter cloth are tied to the connecting holes of the connecting piece by cable ties 4. To firmly fix the filter cloth to the connecting chain, the two sides are provided with edging 8, that is, the thickness of the edging 8 is greater than that of the middle of the filter cloth, so that the filter cloth is not easily torn during operation.
[0014] A spray section 9 is pressed above the filter cloth. The collected grinding fluid is connected to the spray section after being pressurized. The pressurization method can be piston pressurization or water pump pressurization. A receiving tray 11 is provided below the filter cloth, and the receiving tray has mesh holes. A water receiving pool 12 is provided below the mesh holes. An air outlet device is provided in the space surrounding the filter cloth to blow air outward from the outside of the filter cloth 10. A material drop box 5 is provided below the outside of the filter cloth 10. The air outlet device can dry the filter cloth to facilitate the falling off of the slag on the filter cloth, and also directly blow the slag to facilitate its falling off. Nozzles 6 are provided on both sides below the filter cloth, and the nozzles 6 are connected to the water receiving pool 12. Because the thickness of the two sides of the filter cloth is larger than that of the middle part of the filter cloth, the slag is not easy to fall off. Therefore, additional nozzles are provided to rinse it. The rinsing liquid is the cleaning liquid filtered in the water receiving pool.
[0015] The outer edge 10 of the filter cloth is angled inwards from top to bottom. This inward angled design facilitates the falling of slag.
[0016] The specific filtration process is as follows: The filter cloth is continuously rotated by the motor 13. The spray nozzle 9 above the filter cloth sprays pressurized grinding fluid downwards. The grinding fluid passes through the upper layer of the filter cloth, and after filtration, the slag remains on the outer surface of the upper layer of the filter cloth 7, while the liquid continues to flow downwards. When the filter cloth rotates to the outer side, the air outlet blows it dry and blows off the slag adhering to its surface, which falls into the discharge box 5. In addition, the outer side of the filter cloth is set to be inclined downwards and inwards, which facilitates the falling of slag. At this time, some slag will still remain on the surface of the filter cloth. When the filter cloth rotates to the lower layer, the filtered liquid above the filter cloth washes it, and the remaining slag falls into the receiving tray 11. The liquid enters the water receiving pool through the mesh, while the slag remains on the receiving tray. The liquid in the water receiving pool can then undergo the next process, such as further fine filtration.
[0017] During the cleaning process, due to the thicker edging on both sides, some residue always adheres to the edging, regardless of whether it's air blowing or subsequent rinsing. This causes the filter cloth to become unbalanced overall, resulting in an uneven surface. Consequently, the spray nozzles at the top cannot fully contact the filter cloth surface, which over time affects the filtration effect. Therefore, nozzles are installed on both sides below the filter cloth, connected to a water collection tank, effectively adding nozzles on both sides of the filter cloth for rinsing.
