[0036] It should be further understood that the term "and / or" used in the specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0037] An embodiment of the present invention provides a gas-water combined cleaning structure for a chemical oil remover in a rolling system, as Figures 1 to 2As shown in the figure, in the present invention, a pneumatic cleaning structure 1 is laid at the bottom of the chemical oil remover in the rolling system. The pneumatic cleaning structure 1 is connected to a blowing device 3, and a control member 2 is further provided between the pneumatic cleaning structure 1 and the blowing device 3. The control member 2 is used to regulate the opening and closing of the pneumatic cleaning structure 1 at the bottom of the chemical oil remover and the air intake speed. In this embodiment, since the water supplied by the rolling steel turbid ring system cools the equipment and products at the user end and then returns to the chemical oil remover at the return water station for treatment and recycling, the return water often carries scale and iron-containing sludge. It enters the chemical oil remover with the return water and settles inside the mud hopper of the chemical oil remover. Part of it is discharged out of the system through sludge discharge, while a part still adheres to the conical hopper wall and dead corners and cannot be discharged from the system, affecting the operation effect of the chemical oil remover. Therefore, a pneumatic cleaning structure 1 is laid at the bottom of the chemical oil remover in the rolling system, and the air-water combined cleaning method is used, that is, compressed air and water are used to jointly clean the chemical oil remover. When the chemical oil remover withdraws from cleaning the upper packing, the pneumatic cleaning structure 1 added to the four walls at the mud hopper position is synchronously opened, and the bottom sludge discharge valve 5 is opened. Through this air-water combined cleaning method, it is avoided that scale and sludge adhere to the four walls of the mud hopper or form dead corners at the wall joint, and at the same time, the problem of manual entry into the chemical oil remover for cleaning caused by the accumulation of scale and sludge is avoided, improving the work efficiency.

[0038] In this embodiment, the pneumatic cleaning structure 1 includes gas channels respectively arranged at the seam positions of the four walls at the bottom of the chemical oil remover in the rolling system and in the middle of the four walls, and the gas channels have jet orifices 12.

[0039] Furthermore, the gas channels are arranged as air pipes 1 at the seam positions of the four walls at the bottom of the chemical oil remover in the rolling system and in the middle of the four walls. The air pipes 1 are laid in a ring along the position where the mud is stored at the bottom of the chemical oil remover. The air pipes 1 are welded and fixed inside the chemical oil remover, and the air pipes 1 are provided with jet orifices 12.

[0040] By respectively adding air pipes 1 and opening holes at the seam positions of the four walls at the bottom of the chemical oil remover in the rolling system and in the middle of the four walls, the air pipes 1 are laid in a ring along the position where the mud is stored at the bottom of the chemical oil remover. The annular air pipes 1 are welded and fixed inside the chemical oil remover, and holes are opened on the annular air pipes 1 on the inner wall. By opening the compressed air intake valve to blow air, the air-water combined flushing method can be used to quickly clean the chemical oil remover. The cleaning time of the chemical oil remover is greatly shortened, and it can be carried out during the daily repair time of the rolling system, which is beneficial to the stable production of the system and the improvement of water quality.

[0041] In this embodiment, the control member 2 includes a valve, and the valve controls the opening and closing of the air jet openings 12 of the air pipes 1 at the bottom of the chemical oil remover and the air intake speed by adjusting the opening degree. In this embodiment, a valve is added at each position where each external pipe of the chemical oil remover is connected to the annular air pipe 1 for air intake, for controlling whether air intake is required at the position of the mud hopper at the bottom of the chemical oil remover and controlling the air intake speed. This valve can be a throttle valve, and the air intake speed of the air pipe 1 is adjusted by changing the opening degree of the throttle valve. The larger the opening degree of the throttle valve, the larger the gas flow rate and the faster the air intake speed; conversely, it is slower.

[0042] In this embodiment, the bottom of the chemical oil remover of the rolling system further has a water inlet valve 4 and a sludge discharge valve 5. The water inlet valve 4 is used to supply water into the chemical oil remover of the rolling system, and the sludge discharge valve 5 is used to discharge the mud-water mixture in the chemical oil remover of the rolling system. When the chemical oil remover is thoroughly cleaned, first drain the chemical oil remover until the packing is exposed above the water surface, then open one by one the valves of the air pipes 1 added at the bottom of the chemical oil remover, and blow air for 30 minutes to maximally disturb the sludge and scale adhering to the four walls and the dead corners of the wall seams of the chemical oil remover, so that they become loose and fall off from the positions of the four walls or the dead corners of the wall seams of the chemical oil remover. Then open the sludge discharge valve 5 of the chemical oil remover, and at the same time open the upper water inlet valve 4 to start flushing the packing with water. This can discharge the scale and sludge inside the chemical oil remover out of the system, which is beneficial to the stability of the system and the improvement of water quality.

[0043] In this embodiment, an adjusting member is assembled on the air jet opening 12 of the air pipe 1. The adjusting member has a first air outlet and a second air outlet. The first air outlet is in the same direction as the air jet direction of the air jet opening 12, and the air jet direction of the second air outlet is adjustable. When the air jet opening 12 jets air upward to clean the sludge and scale adhering to the four walls and the dead corners of the wall seams of the chemical oil remover, since there is a dead corner position between the two air jet openings 12, the second air outlet of the adjusting member is adjusted up and down to clean the sludge at the dead corner between the two air jet openings 12, so as to maximally disturb the sludge and scale adhering to the four walls and the dead corners of the wall seams of the chemical oil remover.

[0044] In this embodiment, the air blowing device 3 includes an air compressor and an air blowing pipe. The air compressor is connected to the joints at the bottom four walls and the middle of the four walls of the chemical oil remover of the rolling system through the air blowing pipe.

[0045] On the other hand, a gas-water combined cleaning method for the chemical oil remover of the rolling system includes the following steps:

[0046] Obtain the sludge accumulation amount at the bottom of the chemical oil remover of the rolling system;

[0047] According to the sludge accumulation amount, the control member 2 adjusts the opening degree to control the air intake speed;

[0048] The control air blowing device 3 pumps compressed air to the pneumatic cleaning structure 1 laid at the bottom of the chemical oil remover in the rolling system.

[0049] In this embodiment, the control air blowing device 3 pumps compressed air to the pneumatic cleaning structure 1 laid at the bottom of the chemical oil remover in the rolling system, including:

[0050] An air compressor is used to pump compressed air to the air pipe 1 at the joint positions of the four walls and the middle of the four walls at the bottom of the chemical oil remover in the rolling system. The jet nozzles 12 on the air pipe 1 clean the sludge accumulated on the bottom conical hopper wall and the dead corners, and at the same time, the sludge discharge valve 5 is opened to discharge the mud-water mixture;

[0051] After the jet nozzles 12 on the air pipe 1 are closed, the water inlet valve 4 is opened to wash the conical hopper wall and the dead corners to clean the remaining sludge.

[0052] When the chemical oil remover is thoroughly cleaned, first drain the chemical oil remover until the packing is exposed above the water surface, then open the valves of the air pipes 1 added at the bottom of the chemical oil remover one by one and blow air for 30 minutes to maximally disturb the sludge and scale adhering to the four walls and the dead corners of the wall joints of the chemical oil remover, so that they loosen and fall off from the positions of the four walls or the dead corners of the wall joints of the chemical oil remover. Then, the sludge discharge valve 5 of the chemical oil remover is opened, and at the same time, the upper water inlet valve 4 is opened to start flushing the packing with water, which can discharge the scale and sludge inside the chemical oil remover out of the system, being beneficial to the stability of the system and the improvement of water quality. As a further improvement of the present invention: the control air blowing device 3 pumps compressed air to the pneumatic cleaning structure 1 laid at the bottom of the chemical oil remover in the rolling system, and further includes:

[0053] An air compressor is used to pump compressed air to the air pipe 1 at the joint positions of the four walls and the middle of the four walls at the bottom of the chemical oil remover in the rolling system. The first air outlet and the second air outlet of the adjusting member clean the sludge accumulated on the bottom conical hopper wall and the dead corners;

[0054] The second air outlet of the adjusting member is used to clean the sludge in the dead corner between the two jet nozzles 12, and the second air outlet of the adjusting member adjusts up and down along the conical hopper wall.

[0055] Since there is a dead corner position between the two jet nozzles 12, the second air outlet of the adjusting member is set to adjust up and down to clean the sludge in the dead corner between the two jet nozzles 12, maximally disturbing the sludge and scale adhering to the four walls and the dead corners of the wall joints of the chemical oil remover.

[0056] On the other hand, a pneumatic cleaning structure 1 is added around the bottom sludge hopper of the chemical oil remover. The specific cleaning method is as follows: Empty the chemical oil remover until the packing is exposed above the water surface, open the compressed air inlet valve one by one to blow air. After blowing air for half an hour, open the sludge discharge valve 5, and at the same time, wash the packing with water to discharge the accumulated sludge on the oxidized iron sheet and the bottom dead angle out of the system. Then open the blowdown valve of the chemical oil remover, and at the same time, start washing the packing from the upper part with water, so that the oxidized iron sheet and sludge inside the chemical oil remover can be discharged out of the system.

[0057] The present invention aims at the pneumatic cleaning structure 1 at the position of the bottom sludge hopper of the chemical oil remover. When the chemical oil remover withdraws to clean the upper packing, the pneumatic cleaning structure 1 added to the four walls at the position of the sludge hopper is synchronously opened, and the bottom sludge discharge valve 5 is opened. Through this combined air and water cleaning method, it is avoided that the oxidized iron sheet and sludge adhere to the four walls of the sludge hopper or form dead angles at the joint of the wall seams. At the same time, it also avoids the problem of manual entry into the chemical oil remover for cleaning caused by the accumulation of oxidized iron sheet and sludge, and improves the work efficiency.

[0058] Through this combined air and water cleaning method, the cleaning of the chemical oil remover can be quickly realized, the withdrawal time of the chemical oil remover is reduced, which is beneficial to stabilizing the water quality and production.

[0059] Through this combined air and water cleaning method, air blowing cleaning can be synchronously carried out when the chemical oil remover cleans the upper packing, so that the oxidized iron sheet and sludge can be completely discharged out of the system within one packing cleaning cycle, reducing the accumulation of sludge and oxidized iron sheet at the four walls and the joint of the wall seams of the sludge hopper of the chemical oil remover, and reducing the production burden of the next operation process.

[0060] In summary, after those of ordinary skill in the art read the documents of the present invention, all other corresponding transformation schemes made without creative mental labor according to the technical solutions and technical concepts of the present invention shall fall within the scope protected by the present invention.
