Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and in particular to a rubber roller driven magnetic separator filtration device. Background Technology

[0002] A grinding machine is a machine tool that uses a mold to grind the surface of a workpiece. Grinding is typically achieved through the high-speed rotation of a grinding wheel and the combined action of a coolant for cleaning and lubrication. However, during grinding, the coolant often becomes contaminated with iron filings and abrasive particles from the grinding wheel, hindering coolant circulation. Therefore, grinding machines are equipped with magnetic separators to separate the coolant from the iron filings. The magnetic separator contains a magnetic roller and a rubber roller, their outer surfaces tangential. The magnetic roller contains a magnet. As the geared motor drives the magnetic roller to rotate, it attracts iron filings from the coolant. These iron filings are then squeezed out by the rubber roller, expelling the coolant along with the iron filings.

[0003] However, in existing rubber roller filtration devices, the rotation of most rubber rollers relies on the friction between magnetic rollers, which causes the rubber rollers to slip when they encounter oily cutting fluid. Furthermore, during long-term use, due to frictional wear, the rubber rollers can no longer rotate with the magnetic rollers, making it impossible to cooperate with the magnetic rollers to squeeze out the coolant present in the iron filings. Utility Model Content

[0004] To address the technical problem that in existing rubber roller filtration devices, the rotation of most rubber rollers relies on the friction between magnetic rollers, causing the rubber rollers to slip when encountering oily cutting fluid. Furthermore, during long-term use, due to frictional wear, the rubber rollers can no longer rotate with the magnetic rollers, making it impossible to cooperate with the magnetic rollers to squeeze out the coolant present in the iron filings, this utility model provides a rubber roller forced-drive magnetic separator filtration device.

[0005] This utility model is achieved using the following technical solution: a rubber roller driven magnetic separator filter device, comprising a filter box, a water inlet on one side of the filter box, a partition fixedly connected inside the filter box, the partition dividing the internal space of the filter box into a water storage area and a filtration area, protective covers fixedly connected to both sides of the filter box along the horizontal line, a rubber roller rotatably connected between a pair of protective covers, a magnetic roller rotatably connected inside the filtration area, the magnetic roller and the rubber roller being connected by a transmission component, a guide plate for collecting waste material installed on the other side of the filter box, and a water outlet at the bottom of the filter box.

[0006] The above technical solution enables the rubber roller and the magnetic roller to rotate relative to each other via a transmission component, avoiding the slippage phenomenon that occurs when the traditional rubber roller relies on friction between itself and the magnetic roller for rotation, and also preventing the rubber roller from becoming unusable after long-term use.

[0007] As a further improvement to the above solution, the transmission assembly includes a servo motor fixedly mounted on the outer side of the filter housing, parallel to the side of the filter housing. A rotating wheel is fixedly mounted at the output end of the servo motor, and a chain is fixedly mounted around the outer side of the rotating wheel. A pair of sprockets that mesh with the chain are symmetrically fixedly mounted on the outer side of the magnetic roller's shaft.

[0008] As a further improvement to the above scheme, the same chain as the outer side of the rotating wheel is fixed to the outside of the rubber roller shaft, and the chain on the outside of the rubber roller meshes with another sprocket on the outside of the magnetic roller shaft.

[0009] Through the above technical solution, the meshing teeth of the sprocket in the transmission assembly mesh with the gap between the chain, so that the rotation of the servo motor can drive the magnetic roller and the rubber roller to rotate synchronously, and the rotation directions of the rubber roller and the magnetic roller are opposite.

[0010] As a further improvement to the above scheme, an arc-shaped channel is fixed to one side of the baffle in the filtration zone. The arc-shaped channel is located directly below the magnetic roller and is concentric with the outer cylinder of the magnetic roller.

[0011] Through the above technical solution, the arc-shaped channel can make the outer side of the bottom of the magnetic roller have a larger adsorption surface for the coolant, thereby improving the adsorption of iron filings mixed in the coolant.

[0012] As a further improvement to the above solution, an opening is provided on the side of the arc-shaped channel near the servo motor.

[0013] The above technical solution allows the opening to better allow the purified liquid to enter the outlet at the bottom of the filter box from the filtration zone.

[0014] As a further improvement to the above solution, the protective cover is hollow, and an elastic component for buffering the rubber roller is provided inside the protective cover. The elastic component includes a bearing fixed to both ends of the rubber roller shaft, a damper fixed between the bottom end of the bearing and the inner side wall of the protective cover, and a buffer spring installed on the outside of the damper.

[0015] Through the above technical solution, the damping and buffer spring settings in the elastic component can alleviate the vibration generated by the rubber roller when squeezing impurities, and avoid more wear at the meshing point between the sprocket and the chain.

[0016] As a further improvement to the above scheme, a first scraper for scraping the surface of the rubber roller is fixed between a pair of protective covers, and a second scraper for scraping the surface of the magnetic roller is fixed at the top of the guide plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes the meshing arrangement between the sprocket and chain in the transmission assembly to enable the servo motor to drive the magnetic roller and rubber roller to rotate synchronously, with the rotation directions of the rubber roller and magnetic roller being opposite. The arc-shaped channel design allows for a larger surface area for the magnetic roller to absorb coolant, resulting in better adsorption of iron filings mixed in with the coolant. The damping and buffer springs in the elastic assembly alleviate vibrations generated by the rubber roller when squeezing impurities, preventing excessive wear at the meshing point between the sprocket and chain.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please combine Figures 1-5This embodiment of a rubber roller driven magnetic separator filter device includes a filter box 1. The filter box 1 has a water inlet 2 on one side, which is vertically parallel to the outside. A partition 3 is fixedly connected inside the filter box 1, which divides the internal space of the filter box 1 into a water storage area and a filtration area. Protective covers 4 are fixedly connected to both sides of the filter box 1, and a rubber roller 5 is rotatably connected between a pair of protective covers 4. A magnetic roller 6 is rotatably connected inside the filtration area. The magnetic roller 6 and the rubber roller 5 are connected by a transmission component. A guide plate 7 for collecting waste is installed on the other side of the filter box 1, which is vertically parallel to the outside. A water outlet 8 is opened at the bottom of the filter box 1.

[0028] Combination Figure 2 and Figure 4 The transmission assembly includes a servo motor 9 fixedly mounted on the outer side of the filter housing 1, parallel to the side. A rotating wheel 10 is fixedly mounted at the output end of the servo motor 9. A chain 11 is fixedly mounted around the outer side of the rotating wheel 10. A pair of sprockets 12 that mesh with the chain 11 are symmetrically fixedly mounted on the outer side of the rotating shaft of the magnetic roller 6. A chain 11 identical to the outer side of the rotating wheel 10 is fixedly mounted on the outer side of the rotating shaft of the rubber roller 5. The chain 11 on the outer side of the rubber roller 5 meshes with another sprocket 12 on the outer side of the rotating shaft of the magnetic roller 6.

[0029] Servo motor 9 drives rotating wheel 10 to rotate. At this time, the gap between the chain 11 fixed to the outside of rotating wheel 10 will synchronously drive the sprocket 12 meshing with it to rotate. Since the sprocket 12 is fixed to the outside of the magnetic roller 6 shaft on the two horizontal parallel inner sides of the filter box 1, the magnetic roller 6 rotates clockwise on the two horizontal parallel inner sides of the filter box 1. Since the other sprocket 12 fixed to the outside of the magnetic roller 6 shaft meshes with the gap of the chain 11 fixed to the outside of the rubber roller 5 shaft, the rotation of the magnetic roller 6 can drive the rubber roller 5 to rotate in the opposite direction between a pair of protective covers 4.

[0030] Combination Figure 2 and Figure 5 The partition 3 is fixed to one side of the filter area with an arc-shaped channel 13. The arc-shaped channel 13 is located directly below the magnetic roller 6 and is concentric with the outer cylinder of the magnetic roller. An opening 14 is provided on the side of the arc-shaped channel 13 near the servo motor 9.

[0031] The opening 14 lowers the height of the arc-shaped channel 13 on the side of the servo motor 9, making it easier for the filtered liquid to enter the outlet 8 at the bottom of the filter box 1 from the filtration zone.

[0032] Combination Figure 3 The protective cover 4 is hollow, and an elastic component for buffering the rubber roller 5 is provided inside the protective cover 4. The elastic component includes a bearing seat 15 fixed to both ends of the rotating shaft of the rubber roller 5. A damper 16 is fixed between the bottom end of the bearing seat 15 and the inner side wall of the protective cover 4. A buffer spring 17 is installed on the outside of the damper 16.

[0033] The damping 16 and buffer spring 17 in the elastic component can alleviate the vibration generated by the rubber roller 5 when squeezing impurities, and avoid more wear at the meshing point between the sprocket 12 and the chain 11.

[0034] Combination Figure 3 and Figure 4 A first scraper 19 for scraping the surface of the rubber roller 5 is fixed between a pair of protective covers 4, and a second scraper 20 for scraping the surface of the magnetic roller 6 is fixed at the top of the guide plate 7.

[0035] When the magnetic roller 6 rotates the iron scrap to a position between it and the rubber roller 5, the rubber roller 5 will squeeze the waste liquid in the iron scrap, and then after being scraped by the second scraper 20, it will flow out of the equipment from the guide plate 7 for collection. At the same time, the first scraper 19 can remove the impurities adhering to the surface of the rubber roller 5.

[0036] The implementation principle of a rubber roller 5-forced magnetic separator filter device in this application embodiment is as follows:

[0037] During the grinding process, the coolant often contains iron filings and abrasive particles that fall from the grinding wheel;

[0038] First, coolant containing impurities is injected into the water storage area inside the filter box 1 through the water inlet 2 on the upper part of the vertically parallel outer side.

[0039] At this time, as the coolant accumulates in the water storage area, the sand particles contained in the coolant will settle to the bottom of the filter box 1 in the water storage area, thus performing preliminary filtration of the coolant.

[0040] An L-shaped inclined plate 18 is fixed to the inner wall of the filter box 1 located in the water storage area. The bottom of the L-shaped inclined plate 18 is lower than the top of the opening 14 of the partition 3 to prevent some coolant containing impurities from directly rushing into the arc-shaped channel 13.

[0041] When the height of the accumulated coolant in the water storage area is higher than the inlet of the arc-shaped channel 13 and the opening 14 of the baffle 3 in the filtration area, the coolant that has undergone preliminary filtration gradually flows into the arc-shaped channel 13.

[0042] Then, the servo motor 9 is turned on to drive the rotating wheel 10 to rotate. At this time, the gap between the chains 11 fixed to the outside of the rotating wheel 10 will drive the sprocket 12 meshing with itself to rotate synchronously when rotating, so that the magnetic roller 6 rotates clockwise on the two parallel inner sides of the filter box 1, and the rubber roller 5 rotates counterclockwise between a pair of protective covers 4.

[0043] Because a strong magnetic block is installed inside the magnetic roller 6, the magnetic roller 6 can adsorb the iron filings contained in the coolant in the arc channel 13. When the magnetic roller 6 drives the iron filings to rotate to the position between the magnetic roller 6 and the rubber roller 5, the rubber roller 5 will squeeze the waste liquid in the iron filings, and then after being scraped by the second scraper 20, it flows out of the equipment from the guide plate 7 for collection.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
