Description

Technical Field

[0001] This invention relates to the field of filtration equipment technology, and in particular to an automatic cloth-changing filtration device for copper rod rolling fluid. Background Technology

[0002] In the continuous rolling mill of the copper rod production system, multiple parts require rolling fluid for cooling or lubrication during operation. After use, the rolling fluid contains contaminants. If it is reused directly without treatment, it will damage the rolling mill. Therefore, many companies simply discard the used rolling fluid, which not only increases production costs but also harms the surrounding lakes or soil environment. Considering the above, it is necessary to filter and reuse the rolling fluid after it has been used in the rolling mill. Existing filtration equipment mostly uses fixed filter cloths for filtration. After a period of use, the filter cloths become clogged, requiring frequent replacements, which is cumbersome and affects production efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic cloth-changing filtration device for copper rod rolling fluid.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic cloth-changing filtration device for copper rod rolling liquid includes a filter housing and a liquid storage housing, as well as a delivery pump and an inlet pipe for conveying the rolling liquid in the liquid storage housing to the filter housing. A filter cloth frame is provided on one side of the filter housing, and an outlet pipe is provided at the bottom of the filter housing. A mesh belt conveyor chain is installed inside the filter housing, with filter cloth laid on top of the mesh belt conveyor chain, dividing the interior of the filter housing into a dirty liquid chamber and a clear liquid chamber from top to bottom. A collection housing is provided on the side of the filter housing away from the filter cloth frame for collecting the used filter cloth. A first perforation and a second perforation are respectively provided on both sides of the filter housing. The filter cloth has perforations, with the opening height of the first perforation being greater than that of the second perforation. One end of the filter cloth extends through the second perforation to the outside of the filter housing and is wound around the filter cloth frame, while the other end of the filter cloth extends through the first perforation to the inside of the collection housing. A filter cloth winding shaft is provided inside the collection housing for winding up the filter cloth that has moved into the collection housing. Sealing mechanisms are provided at the top of both the first and second perforations for sealing their openings. The system also includes an exhaust fan for evacuating air from the interior of the clear liquid chamber. A negative pressure sensor is installed on the inner wall of the clear liquid chamber for monitoring the negative pressure within the clear liquid chamber.

[0006] Preferably, a liquid level sensor is installed on the inner wall of the waste liquid chamber to monitor the liquid level of the waste liquid in the waste liquid chamber; an overflow pipe is provided inside the waste liquid chamber, with one end of the overflow pipe away from the filter housing extending into the liquid storage housing; and an alarm is also included.

[0007] Preferably, a second transition shell is installed on one side of the filter shell, the opening of the second perforation is located inside the second transition shell, and a return pipe is provided at the bottom of both the second transition shell and the collection shell to guide the rolling liquid collected in the collection shell and the second transition shell into the storage shell.

[0008] Preferably, the collection housing is provided with a positioning roller inside, which is used to position the filter cloth to be rolled up inside the collection housing at an inclined position; it also includes a soot blowing housing, which has a soot blowing hole on the side of the soot blowing housing near the filter cloth; and it also includes an air pump, which is used to blow air into the soot blowing housing.

[0009] Preferably, a first transition housing is installed on the side of the filter housing, and the opening of the first perforation is located inside the first transition housing; a pressing mechanism is provided inside the first transition housing for pressing the filter cloth removed from the opening of the first perforation.

[0010] Preferably, the pressing mechanism includes a mounting housing installed on the inner wall of the top of the first transition housing, a mounting rod installed inside the mounting housing by a spring, and a mounting seat installed at one end of the mounting rod extending to the outside of the mounting housing; a pressing roller is movably installed inside the mounting seat, and water-blocking side wings are installed at intervals on the side of the pressing roller; it also includes a driving component for driving the pressing roller to rotate when changing the fabric.

[0011] Preferably, the inner wall of the mounting base has an arc-shaped structure.

[0012] Preferably, the sealing mechanism includes a telescopic component, and a sealing component is installed at one end of the piston rod of the telescopic component. The outer diameter of the sealing component is larger than the inner diameter of the opening of the first perforation and the second perforation.

[0013] The beneficial effects of this invention are as follows:

[0014] During operation, the rolling liquid in the storage shell is pumped through the inlet pipe to the dirty liquid chamber via a delivery pump. After being filtered by the filter cloth, the rolling liquid flows into the clear liquid chamber. Impurities in the rolling liquid are trapped by the filter cloth, forming a filter cake. During the filtration process, the exhaust fan draws air from the inside of the clear liquid chamber, creating a negative pressure inside the clear liquid chamber, which accelerates the filtration speed of the rolling liquid. The airflow drawn by the exhaust fan circulates from bottom to top in the filter shell, which, in addition to creating a slight negative pressure, can also kill anaerobic bacteria in the rolling liquid and extend its service life. When the negative pressure sensor detects that the negative pressure value in the clear liquid chamber reaches the preset value, the sealing mechanism moves away from the openings of the first and second perforations. At the same time, the filter cloth winding shaft winds up one end of the filter cloth, and the mesh belt conveyor chain drives the filter cloth to move horizontally in the filter shell. The filter cloth frame unwinds the filter cloth, completing the automatic cloth replacement. After the cloth replacement is completed, the sealing mechanism covers the openings of the first and second perforations. This method is convenient and efficient, improving the filtration efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1 to 4 An automatic cloth-changing filtration device for copper rod rolling liquid includes a filter housing 1 and a liquid storage housing 17, as well as a delivery pump 16 and an inlet pipe 25 for conveying the rolling liquid in the liquid storage housing 17 to the filter housing 1. A filter cloth frame 15 is provided on one side of the filter housing 1, and an outlet pipe 13 is provided at the bottom of the filter housing 1. A mesh belt conveyor chain 12 is provided inside the filter housing 1, and a filter cloth 6 is laid on the top of the mesh belt conveyor chain 12, which divides the interior of the filter housing 1 into a dirty liquid chamber 2 and a clean liquid chamber 8 from top to bottom. A collection housing 9 is provided on the side of the filter housing 1 away from the filter cloth frame 15 for collecting the used filter cloth 6. A first perforation 23 and a second perforation are respectively opened on both sides of the filter housing 1. 24. The opening height of the first perforation 23 is greater than the opening height of the second perforation 24. One end of the filter cloth 6 extends through the second perforation 24 to the outside of the filter housing 1 and is wrapped around the filter cloth frame 15. The other end of the filter cloth 6 extends through the first perforation 23 to the inside of the collection housing 9. A filter cloth winding shaft 21 is provided inside the collection housing 9 for winding up the filter cloth 6 that has moved into the collection housing 9. A sealing mechanism 22 is provided at the top of both the first perforation 23 and the second perforation 24 for sealing the openings of the first perforation 23 and the second perforation 24. A fan 14 is also included for evacuating the inside of the clear liquid chamber 8. A negative pressure sensor 11 is installed on the inner wall of the clear liquid chamber 8 for monitoring the negative pressure inside the clear liquid chamber 8.

[0022] During use, the rolling liquid in the storage shell 17 is pumped by the delivery pump 16 through the inlet pipe 25 to the sludge chamber 2. After being filtered by the filter cloth 6, the rolling liquid flows into the clear liquid chamber 8. Impurities in the rolling liquid are trapped by the filter cloth 6 to form a filter cake. During the filtration process, the exhaust fan 14 evacuates air from the inside of the clear liquid chamber 8, creating a negative pressure inside the clear liquid chamber 8, which accelerates the filtration speed of the rolling liquid. In addition, the airflow drawn by the exhaust fan 14 circulates from bottom to top in the filter shell 1, which, in addition to creating a slight negative pressure, can also kill anaerobic bacteria in the rolling liquid and extend the service life of the rolling liquid. When the negative pressure sensor 11 detects that the negative pressure value in the clear liquid chamber 8 reaches the preset value, the sealing mechanism 22 moves away from the openings of the first perforation 23 and the second perforation 24. At the same time, the filter cloth winding shaft 21 winds up one end of the filter cloth 6, the mesh belt conveyor chain 12 drives the filter cloth 6 to move horizontally within the filter housing 1, and the filter cloth frame 15 unwinds the filter cloth 6, completing the automatic replacement of the filter cloth 6. After the replacement is completed, the sealing mechanism 22 blocks the openings of the first perforation 23 and the second perforation 24, making it convenient and efficient to use and improving the filtration efficiency.

[0023] In a preferred embodiment of the present invention, a liquid level sensor 20 is installed on the inner wall of the waste liquid chamber 2 to monitor the liquid level of the waste liquid in the waste liquid chamber 2; an overflow pipe 18 is provided inside the waste liquid chamber 2, with one end of the overflow pipe 18 extending into the liquid storage shell 17 away from the filter shell 1; an alarm 26 is also included, which sounds an alarm when the liquid level sensor 20 detects that the liquid level in the waste liquid chamber 2 is too high, so as to promptly remind the staff to check, and when the rolling liquid level in the waste liquid chamber 2 is too high, the rolling liquid can flow back into the liquid storage shell 17 from the overflow pipe 18.

[0024] In a preferred embodiment of the present invention, a second transition shell 19 is installed on one side of the filter shell 1. The opening of the second perforation 24 is located inside the second transition shell 19. Both the second transition shell 19 and the collection shell 9 are provided with a return pipe at their bottoms, which is used to guide the rolling liquid collected in the collection shell 9 and the second transition shell 19 to the liquid storage shell 17. During the fabric changing process, some of the rolling liquid overflows through the openings of the first perforation 23 and the second perforation 24, and the rolling liquid collected in the collection shell 9 and the second transition shell 19 is guided to the liquid storage shell 17 through the return pipe.

[0025] In a preferred embodiment of the present invention, a positioning roller 5 is provided inside the collection housing 9 to position the filter cloth 6 to be rolled up in the collection housing 9 at an inclined position; a blowing housing 7 is also included, with a blowing hole on the side of the blowing housing 7 near the filter cloth 6; an air pump 10 is also included to blow air into the blowing housing 7. The positioning roller 5 positions the filter cloth 6 to be rolled up in the collection housing 9 at an inclined position, and the air pump 10 blows air into the blowing housing 7. The airflow is ejected from the blowing hole to blow ash off the side of the filter cloth 6, thereby effectively removing filter cake and other impurities from the filter cloth 6 in a timely manner.

[0026] In a preferred embodiment of the present invention, a first transition housing 3 is installed on the side of the filter housing 1, and the opening of the first perforation 23 is located inside the first transition housing 3; a pressing mechanism 4 is provided inside the first transition housing 3 for pressing the filter cloth 6 removed from the opening of the first perforation 23 to prevent excessive rolling liquid in the sewage chamber 2 from flowing out from the opening of the first perforation 23.

[0027] In a preferred embodiment of the present invention, the pressing mechanism 4 includes a mounting housing 43 installed on the inner wall of the top of the first transition housing 3.

The mechanism also includes a driving component for driving the pressing roller 44 to rotate during cloth replacement. During cloth replacement, the driving component drives the pressing roller 44 to rotate. The rotation speed of the pressing roller 44 is the same as the horizontal movement speed of the filter cloth 6. At this time, the spring pushes the pressing roller 44 to press the top of the filter cloth. The water-blocking side wings 45 intercept the rolling liquid flowing out from the opening of the first perforation 23. The gap between two adjacent water-blocking side wings 45 can accommodate the filter cake on the filter cloth 6, so as to prevent the filter cake on the filter cloth 6 from not moving into the collection housing 9 when the pressing roller 44 presses the filter cloth 6.

[0028] As a preferred embodiment of the present invention, the inner wall of the mounting base 41 is an arc-shaped structure, and the side of the water-blocking wing 45 away from the pressing roller 44 is in contact with the arc surface inside the mounting base 41, so as to prevent the rolling liquid from flowing from the mounting base 41 into the collection shell 9 during the pressing process.

[0029] In a preferred embodiment of the present invention, the sealing mechanism 22 includes a telescopic component 221. A sealing component 222 is installed at one end of the piston rod of the telescopic component 221. The outer diameter of the sealing component 222 is larger than the inner diameter of the opening of the first through hole 23 and the second through hole 24. The sealing component 222 can be pushed by the telescopic component 221 to block and seal the opening of the first through hole 23 and the second through hole 24.

[0030] In a preferred embodiment of the present invention, the sealing component 222 is made of materials such as rubber or silicone. In this embodiment, the sealing component 222 is preferably made of rubber.
