Description

Technical Field

[0001] This utility model relates to grinding fluid filtration equipment, and more particularly to a mobile online grinding fluid filtration device. Background Technology

[0002] In metal grinding, grinding fluid ensures machining quality through cooling, lubrication, and chip removal. However, its circulation and purification effectiveness is limited by the inherent defects of traditional filtration methods. Most grinding machines have built-in circulating water tanks, using simple filter screens or natural sedimentation to coarsely filter the used grinding fluid. Simple filter screens generally have low filtration accuracy, making it difficult to effectively intercept fine metal chips, grinding wheel particles, and colloidal impurities. Furthermore, filter screens can only intercept larger particles, while the continuous accumulation of fine particles leads to filter clogging and frequent replacements, sometimes even requiring the addition of fresh fluid to dilute the contaminant concentration, further increasing consumable costs and the burden of waste fluid disposal. Natural sedimentation relies on long periods of static separation, which is space-consuming and inefficient. These crude filtration methods not only accelerate the oxidation and deterioration of the grinding fluid and reduce its lubrication performance, but also cause workpiece surface scratches, dimensional accuracy fluctuations, and abnormal tool wear, becoming bottlenecks restricting machining stability and sustainable production.

[0003] To address these issues, this application proposes a solution. Summary of the Invention

[0004] Purpose of the utility model: The purpose of this utility model is to provide a mobile online grinding fluid filtration device that can miniaturize the equipment for filtering grinding fluid and integrate it into a portable housing, while ensuring the filtration effect of the grinding fluid.

The slag discharge unit includes a slag discharge bucket, a filter basket, and a slag inlet. The filter basket is disposed inside the slag discharge bucket, and the slag inlet is disposed above the filter basket and connected to the slag discharge pipe.

[0006] After the precision filtration unit filters the grinding fluid, the solid particles adhering to the filter tank are collected and discharged uniformly by the slag discharge unit.

[0007] Preferably, the box body is provided with a dirty liquid tank, the slag discharge unit is set on the top of the dirty liquid tank by a support frame, the slag discharge bucket is open from top to bottom, and the bottom opening is connected to the top opening of the dirty liquid tank.

[0008] The support frame is used to support the slag discharge unit inside the housing, and the opening at the bottom of the support frame is used for the grinding fluid that has been filtered to remove solid particles to flow out.

The fixed rail is fixedly installed on the top of the dirty liquid tank, and the sliding rail is fixedly connected to the support frame, driving the slag discharge bucket to move along the slide rail. A door panel that can be opened and closed is provided at a corresponding position on the tank body, allowing the slag discharge bucket to slide out for slag removal.

[0013] The slide rail is designed to drive the support frame and the slag discharge unit above the support frame to move along the direction of the slide rail, so that the entire slag discharge unit can be transferred out of the box for slag cleaning.

[0014] Preferably, the sliding rail includes multiple interconnected rail segments, with adjacent rails and the rails and the fixed rail interlocked into a sliding connection via grooves.

[0015] Preferably, the slag discharge unit is also provided with a bucket lid, which is closable and located on the top of the slag discharge bucket. The slag inlet is located on the bucket lid and is detachably connected to the slag discharge pipe.

[0018] Preferably, the precision filtration unit further includes a backflush port, which is connected to the filter outlet to introduce external compressed air.

[0019] The backflush port is designed to introduce external compressed air to backflush and clean the inside of the filter canister.

[0020] Preferably, the bottom of the housing is provided with multiple casters.

[0021] The casters are designed to facilitate the movement of the entire device.

[0022] Beneficial effects: Compared with the prior art, this utility model has the following advantages:

[0023] (1) By integrating the precision filtration unit and the slag discharge unit into a movable box, the efficient interception and collection of solid particles in the grinding fluid is achieved, while ensuring the stability of the filtration flow rate and improving the convenience of mobile transportation.

[0024] (2) By setting a water receiving box below the slag discharge bucket, some of the grinding fluid remaining in the filter basket can fall into the water receiving box instead of dripping onto the ground when the slag discharge unit is cleaning the slag.

[0025] (3) By setting the slide rail, the entire slag discharge unit can be quickly slid out of the box, which makes it easier to clean the slag discharge unit in an open space, thereby improving the cleaning efficiency and the cleaning effect. Attached Figure Description

[0033] Example 1:

[0034] See appendix Figures 1-6Figure 1 shows a mobile online grinding fluid filtration device of the present invention, which includes a movable housing 1.

The filter basket 6 is set inside the slag discharge bucket 5, and the slag inlet 7 is set above the filter basket 6 and connected to the slag discharge pipe 4.

[0035] After the precision filtration unit filters the grinding fluid, the solid particles adhering to the filter tank 2 are collected and discharged uniformly through the filter basket 6 in the slag discharge unit.

[0036] In this embodiment, a dirty liquid tank 8 is provided inside the housing 1. The slag discharge unit is set on the top of the dirty liquid tank 8 through the support frame 9. The slag discharge bucket 5 is vertically connected, and the bottom opening is connected to the top opening of the dirty liquid tank 8. The support frame 9 is used to support the slag discharge unit inside the housing 1. The opening at the bottom of the support frame 9 is used for the grinding fluid that has been filtered to remove solid particles to flow out.

[0037] In this embodiment, a filter pump 10 is installed in the dirty liquid tank 8, and the filter pump 10 draws dirty liquid and delivers it to the filter tank 2.

[0038] In this embodiment, a water receiving box 11 is provided below the slag discharge bucket 5, and one end of the water receiving box 11 is rotatably connected to the support frame 9 via a rotating shaft 12.

[0039] The water receiving box 11 is rotatably connected to the support frame 9 by the rotating shaft 12. In the working state, the water receiving box 11 is affected by its own weight and rotates around the rotating shaft 12, opening downwards, and the grinding fluid flows into the dirty liquid tank 8 below the water receiving box 11.

[0040] In this embodiment, a set of parallel slide rails are provided on the top of the dirty liquid tank 8. Each slide rail includes a fixed rail 13 and a sliding rail 14. The fixed rail 13 is fixedly installed on the top of the dirty liquid tank 8, and the sliding rail 14 is fixedly connected to the support frame 9, which drives the slag discharge bucket 5 to move along the slide rail. A door panel 15 that can be opened and closed is provided on the corresponding position of the tank body 1, so that the slag discharge bucket 5 can slide out for slag removal.

[0041] The slide rail is designed to drive the support frame 9 and the slag discharge unit above the support frame 9 to move along the direction of the slide rail, so that the entire slag discharge unit can be transferred out of the box 1 for slag cleaning.

[0042] In this embodiment, the sliding rail 14 includes multiple interconnected rails, and adjacent rails and the rails and the fixed rail 13 are interlocked to form a sliding connection through concave and convex grooves.

[0043] In this embodiment, the slag discharge unit is also provided with a bucket cover 16. The bucket cover 16 is openable and closable and is located on the top of the slag discharge bucket 5. The slag inlet 7 is located on the bucket cover 16 and is detachably connected to the slag discharge pipe 4.

[0044] In this embodiment, a clean liquid tank 17 is provided at the bottom of the precision filtration unit. The filter tank 2 in the precision filtration unit is connected to the clean liquid tank 17 through a clean liquid pipe 18. A liquid supply pump 19 is provided in the clean liquid tank 17. The liquid supply pump 19 draws clean liquid for use by the machine tool. The clean liquid tank 17 is used to temporarily store the filtered grinding fluid and to provide the filtered grinding fluid to the machine tool for use.

[0045] In this embodiment, the precision filtration unit also includes a backflush port 20, which is connected to the filter outlet 21 to introduce external compressed air. The backflush port 20 is designed to introduce external compressed air to backflush and clean the inside of the filter tank 2.

[0046] In this embodiment, the bottom of the housing 1 is provided with multiple casters 22, and the design of the casters 22 facilitates the transportation of the entire device.

[0047] Example 2:

[0048] During operation, the grinding fluid to be filtered enters the dirty fluid tank 8 inside the housing 1 through the dirty fluid inlet 23. The grinding fluid in the dirty fluid tank 8 is drawn out by the filter pump 10 and transported into the filter tank 2. After the dirty fluid enters the filter tank 2 through the filter inlet 3, it effectively intercepts solid particles under the action of the filter element. The grinding fluid with impurities removed flows out from the filter outlet 21 and flows into the clean fluid tank 17 through the clean fluid pipe 18. The grinding fluid in the clean fluid tank 17 is drawn out by the liquid supply pump 19 and discharged from the clean fluid outlet for use on the machine.

[0049] After filtration for a period of time, a large number of solid particles will accumulate in the filter tank 2, reducing the flow rate of the filter tank 2. At this time, the filter tank 2 stops inlet and outlet liquid and starts the back-flushing cleaning process. Compressed air is introduced into the filter tank 2 through the back-flushing port 20. The compressed air blows the solid particles adhering to the filter element in the filter tank 2, along with the grinding fluid remaining in the filter tank 2, out from the filter inlet 3 and into the slag discharge tank 5 through the slag discharge pipe 4. The filter basket 6 in the slag discharge tank 5 collects the solid particles, and the grinding fluid flows out from the filter holes of the filter basket 6. At this time, the water receiving box 11 is rotatably connected to the support frame 9 through the rotating shaft 12. Under the influence of its own weight, the water receiving box 11 rotates downward and is in an open state. The grinding fluid flows into the dirty liquid tank 8 below.

[0050] After backflushing, when a large amount of solid particles accumulate in the slag discharge bucket 5, affecting the slag discharge efficiency, the slag discharge bucket 5 is cleaned. At this time, the door panel 15 on the box 1 is opened and closed, the quick-connect joint on the slag discharge pipe 4 and the slag inlet 7 is disconnected, the slag discharge bucket 5 is pulled, and the slag discharge bucket 5 is pulled out of the box 1 along the slide rail. The bucket cover 16 is opened, the filter basket 6 is taken out, and the solid particles inside the filter basket 6 are cleaned. The filter basket 6 is then put back into the slag discharge bucket 5. During the slag cleaning, the downward moving end of the water receiving box 11 is supported by the top end face of the dirty liquid tank 8, so that the water receiving box 11 is kept horizontal. At this time, it can be ensured that the grinding fluid remaining in the slag discharge bucket 5 during the slag cleaning process can be collected in the water receiving box 11 and will not fall to the ground.
