Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a machine tool water tank with an iron filings filtering function. Background Art

[0002] In the field of machining mechanical parts, when a machine tool processes parts, it needs to be used in conjunction with corresponding cutting fluid. The machine tool water tank is an essential mechanism of the machine tool and is used to receive and recycle the cutting fluid. The recycled cutting fluid can be pumped by a water pump and sent back to the machine tool for recycling.

[0003] However, during the machining process of parts, a large amount of iron filings and impurities will inevitably be generated. If they are directly recycled without treatment, it may affect the machining of tools and other components.

[0004] Therefore, a water tank that can filter iron filings in the recycled cutting fluid and is easy to clean is very necessary. Summary of the Utility Model

[0005] The purpose of the utility model is to address the above problems existing in the prior art and propose a machine tool water tank with an iron filings filtering function, which solves the problem that the recycled cutting fluid after machining parts by the existing machine tool needs to be filtered.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A machine tool water tank with an iron filings filtering function includes a water receiving tank and a box body located below the water receiving tank. It is characterized in that the box body has a first filtering chamber, a precipitation chamber, and a second filtering chamber that are sequentially connected. The top of the first filtering chamber is open, and a filtering basket with an open top is arranged in the first filtering chamber. The filtering basket has filtering holes. A handle is connected to the top of the filtering basket, and the filtering basket can be separated from the first filtering chamber through the top opening of the first filtering chamber. The outlet of the water receiving tank faces the filtering basket and is adjacent to the opening at the top of the first filtering chamber. A filter screen is fixed in the second filtering chamber.

[0008] When the machine tool water tank with iron filings filtering function is in use, the water receiving tank receives the cutting fluid to be recycled. The cutting fluid flows along the water receiving tank in one direction towards the filtering chamber, and under the action of its own gravity, it passes downward through the top of the filtering basket and enters the filtering basket. The cutting fluid in the filtering basket can pass through the filtering holes on the filtering basket, and the cutting fluid is initially filtered by the filtering holes, so that impurities such as iron filings in the cutting fluid are left in the filtering basket. The cutting fluid that has been initially filtered flows from the filtering chamber one to the precipitation chamber. During the flow in the precipitation chamber, the impurities or fine iron filings in the cutting fluid will naturally precipitate downward and stay at the bottom of the precipitation chamber, no longer flowing with the cutting fluid. The cutting fluid flowing from the precipitation chamber to the filtering chamber two can be filtered through a filter screen. Here, a filter screen with smaller filter holes can be selected to achieve static filtration of the cutting fluid, so that the filtered cutting fluid can meet the requirements for reuse. After the machine tool water tank has been used for a long time, the filtering basket can be lifted upward through the opening at the top of the filtering chamber one by holding the handle to take out the filtering basket. After cleaning the iron filings and impurities in the filtering basket, it can be re-placed into the filtering chamber one. This cleaning process only requires lifting and lowering, and the cleaning and maintenance are relatively convenient.

[0009] In the above-mentioned machine tool water tank with iron filings filtering function, the filtering basket includes a basket body in the shape of a cuboid and a bottom frame fixed to the bottom of the basket body. The above-mentioned filtering holes are located on the side and bottom of the basket body. The bottom frame supports the basket body, leaving a gap at the bottom of the basket body, so that the filtering holes on the side and bottom of the basket body can filter simultaneously, improving the filtering efficiency.

[0010] In the above-mentioned machine tool water tank with iron filings filtering function, the number of the filtering baskets is several and they are distributed in a row close to the side of the box body. The distribution direction of the several filtering baskets is perpendicular to the opening direction of the water receiving tank. A water inlet one is penetrated and opened on the side wall of the filtering chamber one of the box body facing the water receiving tank. The top wall position of the water inlet one is lower than the top position of the filtering basket. Using several filtering baskets for filtering can clean separately according to different impurities in each position, improving the cleaning efficiency. The low top wall position of the water inlet one can block the filtering basket to prevent the filtering basket from moving and affecting the filtering.

[0011] In the above-mentioned machine tool water tank with iron filings filtering function, the filtering chamber one and the precipitation chamber are connected and communicated through a separation chamber. The separation chamber is located below the water receiving tank, and the filtering chamber one is connected and communicated with the separation chamber through the above-mentioned water inlet one. The separation chamber is connected and communicated with the precipitation chamber through a water inlet two. The height of the water inlet two is less than the height of the separation chamber and the water inlet two is arranged close to the bottom surface of the separation chamber. The water inlet two is arranged close to the bottom surface, so that the impurities suspended above the cutting fluid entering the separation chamber can be separated and retained in the separation chamber. Of course, in order to ensure the separation effect, the top surface position of the water inlet two should be lower than the liquid level height. Preferably, the height of the water inlet two is half or even one-third of the height of the separation chamber.

[0012] In the above-mentioned machine tool water tank with an iron filings filtering function, a water passing port three is provided to connect the sedimentation chamber and the second filtering chamber. An insertion socket is arranged at the water passing port three in the sedimentation chamber, and a magnetic member is inserted vertically in the insertion socket. The magnetic member can be a magnet, which can generate a magnetic attraction force on the iron filings to adsorb the iron filings. By inserting the magnetic member at the water passing port three, the iron filings flowing from the water passing port three to the second filtering chamber can be filtered out.

[0013] In the above-mentioned machine tool water tank with an iron filings filtering function, a filtering base with an insertion port is connected in the second filtering chamber of the box body. The above-mentioned filter net is inserted obliquely in the insertion port relative to the vertical plane, and the top position of the filter net is closer to the above-mentioned water passing port three than the bottom position. The filter net arranged in an inserted manner can be conveniently disassembled and cleaned.

[0014] In the above-mentioned machine tool water tank with an iron filings filtering function, both the filter net and the insertion socket are arranged close to the side of the box body, and the filter net, the insertion socket and the filtering basket are arranged on the same side close to the box body. Arranging them on the same side can facilitate the disassembly and assembly process on one side.

[0015] In the above-mentioned machine tool water tank with an iron filings filtering function, a water pump is also fixed on the box body. The inlet of the water pump is located in the second filtering chamber, and the inlet and the water passing port three are respectively located on both sides of the filter net. The cutting fluid filtered by the filter net can be pumped by the water pump and sent to the machine tool for recycling.

[0016] In the above-mentioned machine tool water tank with an iron filings filtering function, an oil-water separator is connected to the inlet end of the water pump. The oil and water are separated by the oil-water separator to improve the filtering effect.

[0017] Compared with the prior art, the machine tool water tank with an iron filings filtering function has the following advantages:

[0018] 1. Through multiple filtrations of the filtering basket, separation chamber, sedimentation chamber, magnetic member and filter net, the filtered cutting fluid can meet the usage requirements of the machine tool, realizing the recycling of the cutting fluid while avoiding damage to the machine tool tools and components.

[0019] 2. The filtering basket, magnetic member and filter net are detachable and arranged on the same side of the box body, which facilitates the cleaning of impurities. Description of the Drawings

Specific embodiments

[0024] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0025] As Figure 1 、 Figure 2 and Figure 3 shown, the machine tool water tank with iron filings filtering function includes a water receiving tank 1 and a box body 2 located below the water receiving tank 1. The box body 2 is internally provided with a first filtering chamber 3, a separation chamber 12, a sedimentation chamber 4 and a second filtering chamber 5 which are sequentially connected. In this embodiment, the number of the first filtering chamber 3, the separation chamber 12, the sedimentation chamber 4 and the second filtering chamber 5 is two and they are all distributed in the same horizontal plane. The two groups of cavities are symmetrically arranged, and the connection positions between the cavities enable the cutting fluid in the box body 2 to flow in an S shape to achieve the best filtering effect.

[0026] For the convenience of description, the position and connection relationship of one group of the first filtering chamber 3, the separation chamber 12, the sedimentation chamber 4 and the second filtering chamber 5 are taken as an example for structural description.

[0027] The top of the first filtering chamber 3 is open, and several filtering baskets 6 with open tops are arranged inside the first filtering chamber 3. The size of the first filtering chamber 3 generally matches the size of the several filtering baskets 6, enabling the filtering baskets 6 to be detached from the first filtering chamber 3 through the top opening thereof. The number of the filtering baskets 6 is several and they are arranged closely in a straight line. The several filtering baskets 6 are distributed close to the side wall of the box body 2, and the distribution direction of the several filtering baskets 6 is perpendicular to the opening orientation of the water receiving tank 1. For example, as shown in the figure, the notch of the water receiving tank 1 is arranged forward, while the filtering baskets 6 are distributed in the left-right direction. The overall length of the two groups of filtering baskets 6 after being arranged in contact is greater than the width of the notch of the water receiving tank 1 so that the cutting fluid can flow into the filtering baskets 6. The outlet of the water receiving tank 1 faces the filtering baskets 6 and is arranged adjacent to the opening at the top of the first filtering chamber 3. The side wall of the first filtering chamber 3 facing the water receiving tank 1 is located below the notch of the water receiving tank 1, and a first water passing port 19 communicating the first filtering chamber 3 and the separation chamber 12 is formed through the side wall. The top wall position of the first water passing port 19 is lower than the top position of the filtering basket 6. In this embodiment, the filtering basket 6 includes a basket body 10 in a cuboid shape, a bottom frame 11 fixed to the bottom of the basket body 10, and a handle 8 fixed to the top of the basket body 10. Several filtering holes 7 are formed through the side and bottom of the basket body 10, and the number of the bottom frames 11 is two and they are fixed to both sides of the bottom of the basket body 10.

[0028] The separation chamber 12 is located below the water receiving tank 1. The separation chamber 12 is communicated with the precipitation chamber 4 through a second water passing port 13. The height of the second water passing port 13 is less than the height of the separation chamber 12, and the second water passing port 13 is arranged close to the bottom surface of the separation chamber 12. In this embodiment, the height of the second water passing port 13 is less than half of the height of the separation chamber 12, preferably one-third.

[0029] The precipitation chamber 4 is a cavity with a flat bottom. It is connected to the second filtration chamber 5 through the third water inlet 20. The second water inlet 13 and the third water inlet 20 are respectively located at both ends of the precipitation chamber 4. The side wall of the precipitation chamber 4 near the third water inlet 20 has a socket 14. The socket 14 is in the shape of a square tube and is vertically installed, that is, the top of the socket 14 is open, the bottom of the socket 14 is fixed to the box body 2, and a communication port communicating with the third water inlet 20 is penetrated and opened on the side of the socket 14. A magnetic part 15 is inserted vertically in the socket 14. The magnetic part 15 includes a magnetic sleeve, a magnetic force plate inserted in the magnetic sleeve, and a limiting frame fixed on the outer side of the magnetic sleeve. The magnetic force plate is in the shape of a plate and is a magnet that can generate a magnetic attraction force on iron impurities. A cover is fixed to the top of the magnetic force plate, and a handle is fixed to the top of the cover. The magnetic sleeve is in the shape of a square tube with a closed bottom and is matched with the cover at the top to achieve closure. The outer side of the limiting frame is adjacent to the inner wall of the socket 14 to limit the position of the magnetic part 15 and keep the magnetic part 15 in a vertical state. At the same time, through the abutment between the limiting frame and the side wall of the socket 14 and the bottom surface of the precipitation chamber 4, there is a distance between the bottom of the magnetic sleeve and the bottom surface of the precipitation chamber 4 and between the outer side of the magnetic sleeve and the inner wall of the socket 14, which is convenient for the cutting fluid to pass through. In this embodiment, the limiting frame includes several rod-shaped support rods, and several support rods are respectively vertically installed and horizontally arranged on the outer side of the magnetic sleeve to limit the height and the front, rear, left, and right positions of the magnetic sleeve.

[0030] A filter base 16 with an insertion port is connected in the second filtration chamber 5 of the box body 2. The filter base 16 is generally U-shaped and is inclined relative to the vertical plane. The insertion port faces upward, and the port position of the insertion port is closer to the third water inlet 20 than the bottom of the filter base 16. Straight grooves are opened on the three side walls in the filter base 16. The filter net 9 is in the shape of a plate and is inserted into the insertion port along the straight grooves on both sides of the filter base 16 and penetrates into the straight groove at the bottom of the filter base 16. A handle for conveniently extracting the filter net 9 is provided at the top of the filter net 9. In this embodiment, both the filter net 9 and the socket 14 are arranged near the side of the box body 2 on the front side, that is, the filter net 9, the socket 14, and the filter basket 6 are arranged on the same side close to the box body 2.

[0031] A water pump 17 is also fixed on the box body 2. The inlet of the water pump 17 is located in the second filtration chamber 5 and the inlet and the third water inlet 20 are respectively located on both sides of the filter net 9. An oil-water separator 18 is also connected to the inlet end of the water pump 17.

[0032] In addition, a filter box with an open top is provided on the top of the box body 2 to receive the cutting fluid leaking from other parts of the machine tool; an oil receiving box is also connected to the top of the box body 2 beside the oil-water separator 18.

[0033] When this machine tool water tank with iron filings filtering function is in use, the water receiving tank 1 receives the cutting fluid that needs to be recycled. The cutting fluid flows along the water receiving tank 1 towards the first filtering chamber 3, and under the action of its own gravity, it passes downward through the top of the filtering basket 6 and enters the filtering basket 6. The cutting fluid in the filtering basket 6 can pass through the filtering holes 7 on the side and bottom of the filtering basket 6, and the cutting fluid is initially filtered by the filtering holes 7, so that impurities such as iron filings in the cutting fluid remain in the filtering basket 6.

[0034] The cutting fluid that has been initially filtered flows into the separation chamber 12 through the first water inlet 19. During the flow in the separation chamber 12, some impurities will precipitate downward to the bottom of the separation chamber 12, and some impurities float on the liquid surface. When the cutting fluid flows to the second water inlet 13, the cutting fluid at the lower part flows through the second water inlet 13 towards the precipitation chamber 4, and the impurities on the top surface of the cutting fluid are separated and remain in the separation chamber 12.

[0035] The cutting fluid that enters the precipitation chamber 4 flows towards the third water inlet 20. And during the flow, impurities continuously precipitate and stay in the precipitation chamber 4. The cutting fluid flows into the communication port of the socket 14 and flows through the gap between the magnetic sleeve and the socket 14 towards the third water inlet 20. The magnetic force plate in the magnetic sleeve adsorbs the iron filings in the cutting fluid.

[0036] After the cutting fluid flows into the second filtering chamber 5 through the third water inlet 20, it is finely filtered again by the filter net 9 and then transported to the water pump 17. The filtered cutting fluid can be pumped by the water pump 17 and sent back to the machine tool for reuse.

[0037] After this machine tool water tank has been used for a long time, the filtering basket 6 can be lifted upward through the opening at the top of the first filtering chamber 3 by holding the handle 8 to take out the filtering basket 6. After cleaning the iron filings and impurities in the filtering basket 6, it is re-placed into the first filtering chamber 3. Similarly, the magnetic part 15 is pulled out through the handle for cleaning, and the filter net 9 is pulled out through the handle for cleaning. After cleaning, it can be re-inserted.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
