[0001] This utility model relates to the technical field of structural steel, and in particular to the technical field of surface polishing of flat steel. Background Technology

[0002] Flat steel is a commonly used type of steel. During its production, the surface of the flat steel needs to be polished to meet the requirements of its use.

[0003] Existing patent CN218488009U discloses a flat steel surface polishing machine that can polish both sides of the flat steel; however, it relies on magnets located on a slope to process iron particles in cooling water. Since the water passing through the magnets is flowing and has a large flow velocity, the iron particles adsorbed on the magnets are easily washed away, resulting in poor separation of iron particles. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a flat steel surface polishing machine, which can effectively separate iron particles in the cooling water and prevent iron particles from entering the water pump and damaging it.

[0005] To achieve the above objectives, this utility model proposes a flat steel surface polishing machine, including a polishing box, a cooling water pipe, a cooling water treatment tank, an air extractor, and a guide pipe. The polishing box has an outwardly protruding inlet and outlet. A polishing mechanism is located inside the polishing box. The cooling water pipe extends from the outside of the polishing box through the side wall into the interior, cooperating with the polishing mechanism. A cooling water treatment tank is fixed to the bottom of the polishing box, and its top wall serves as the bottom wall of the polishing box. A drain pipe is installed on the bottom wall of the polishing box. An air extraction pipe is connected to the side wall of the cooling water treatment tank and is connected to the air extractor. A vertically arranged partition plate is fixed to the bottom wall of the cooling water treatment tank, dividing the area below the upper surface of the partition plate into two water storage chambers. The outlet end of the drain pipe... Above one of the water storage chambers, each water storage chamber is equipped with a water pump. The water pump is located outside the polishing box. The water inlet of the water pump is connected to the water storage chamber through a first connecting pipe. The connection between the first connecting pipe and the water storage chamber is located in the middle of the water storage chamber. The water outlet of the water pump is connected to the cooling water pipe through a second connecting pipe. A second valve is installed on the second connecting pipe. Inside the cooling water treatment box, there is a guide half-pipe. The outer wall of the guide half-pipe is hinged inside the cooling water treatment box. A cylinder is installed on the cooling water treatment box. The piston rod of the cylinder abuts against the outer wall of the guide half-pipe. The cylinder is lower than the hinge point of the guide half-pipe. The guide half-pipe has two postures. When the guide half-pipe is in different postures, the lowest point of the guide half-pipe is located directly above the different water storage chambers. The water falling from the drain pipe falls onto the inner wall of the guide half-pipe.

[0006] Preferably, the bottom wall of the polishing box is funnel-shaped.

[0007] Preferably, the bottom walls of both the inlet and outlet slope downwards from the side furthest from the polishing box.

[0008] Preferably, the air inlet of the air extraction pipe is higher than the water outlet of the drain pipe.

[0009] Preferably, a filter screen is provided at the water inlet end of the first connecting pipe.

[0010] Preferably, a magnet is provided on the bottom wall of the water storage cavity.

[0011] The beneficial effects of this utility model are as follows: By combining the downpipe and the guide half-pipe, the cooling water in the two water storage chambers can be allowed to settle and precipitate in turn, so that the iron particles in the cooling water can be fully separated, which can effectively prevent the iron particles from entering the water pump and damaging the water pump.

An air extraction pipe 21 is connected to the side wall of the cooling water treatment tank 2. The air extraction pipe 21 is connected to an air extraction machine 22.

[0018] A vertically arranged partition plate 20 is fixed on the bottom wall of the cooling water treatment tank 2. The partition plate 20 divides the area of ​​the cooling water treatment tank 2 below the upper surface of the partition plate 20 into two water storage chambers 3. The outlet end of the downpipe 15 is located directly above one of the water storage chambers 3. Each water storage chamber 3 is equipped with a water pump 30. The water pump 30 is located outside the polishing box 1. The water inlet end of the water pump 30 is connected to the water storage chamber 3 through a first connecting pipe 31. The connection point between the first connecting pipe 31 and the water storage chamber 3 is located in the middle of the water storage chamber 3. The water outlet end of the water pump 30 is connected to the cooling water pipe 10 through a second connecting pipe 32. A second valve 34 is installed on the second connecting pipe 32. The second valve 34 is an electrically controlled valve.

[0019] The cooling water treatment tank 2 is equipped with a guide half-pipe 25 inside. The outer wall of the guide half-pipe 25 is hinged to the inside of the cooling water treatment tank 2. A cylinder 26 is installed on the cooling water treatment tank 2. The piston rod of the cylinder 26 abuts against the outer wall of the guide half-pipe 25. The cylinder 26 is lower than the hinge point of the guide half-pipe 25. The guide half-pipe 25 has two postures. When the guide half-pipe 25 is in different postures, the lowest point of the guide half-pipe 25 is located directly above the water storage chamber 3. The water falling from the drain pipe 15 falls onto the inner wall of the guide half-pipe 25. The two postures of the guide half-pipe 25 are switched by the cylinder 26.

[0020] In order to allow iron particles to be discharged smoothly from the polishing box, the bottom wall of the polishing box 1 is funnel-shaped.

[0021] Example 2:

[0023] Example 3:

[0024] To prevent the air extraction pipe 21 from drawing in cooling water, the air inlet of the air extraction pipe 21 is higher than the water outlet of the drain pipe 15.

[0025] Example 4:

[0026] To prevent iron particles from entering the water pump and damaging it, a filter screen 33 is installed at the water inlet end of the first connecting pipe 31.

[0027] To improve the separation effect of iron particles, a magnet 35 is provided on the bottom wall of the water storage cavity 3.

[0028] The working process of this utility model:

[0029] In the operation of this utility model flat steel surface polishing machine, the flat steel passes through the polishing box 1. When the flat steel passes through the polishing box 1, the polishing mechanism inside the polishing box 1 polishes the flat steel. During polishing, the cooling water pipe 10 sprays water onto the flat steel to cool it. The cooling water pipe 10 is supplied with water from the water storage chamber 3 on the left. After a period of time, a certain amount of cooling water accumulates in the polishing chamber 1. The first valve 16 is opened, and the water in the polishing chamber 1 flows into the left water storage chamber 3. At the same time, the water supply of the cooling water pipe 10 is switched to the right water storage chamber 3. After the cooling water in the polishing chamber 1 is basically drained, the first valve 16 is closed, and the left water storage chamber 3 undergoes sedimentation, with iron particles settling to the bottom of the water storage chamber 3. When a certain amount of cooling water accumulates in the polishing chamber 1 again, the cylinder 26 pushes the guide half-pipe 26 to rotate, opening the first valve 16. The cooling water flowing out of the polishing chamber 1 flows into the right water storage chamber 3 through the guide half-pipe 26. At the same time, the water supply of the cooling water pipe 10 is switched to the left water storage chamber 3. After the cooling water in the polishing chamber 1 is basically drained, the first valve 16 is closed, and the right water storage chamber 3 undergoes sedimentation, with iron particles settling to the bottom of the water storage chamber 3. This process is repeated.

[0030] Each time the first valve 16 is opened, the air pump 22 draws air, causing the cooling water treatment tank 2 to be under negative pressure, which accelerates the outflow of cooling water from the polishing tank 1.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
