DETAILED DESCRIPTION

[0019] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0020] Example 1 A steel strip cooling device for preventing the steel strip from yellowing, such as Figure 1-10 As shown, it includes a bottom plate 1; It also includes a power unit, a mounting plate 1 2, a circulating water cooling splint 3, a mounting plate 2 6, an acoustic sensor 7 and a circulating water cooling jacket 9; the bottom plate 1 is connected to the power unit; the power unit is connected to the mounting plate 1 2 and the mounting plate 2 6, and the mounting plate 1 2 and the mounting plate 2 6 are symmetrically arranged up and down; a circulating water cooling splint 3 is fixedly connected to the facing sides of the mounting plate 1 2 and the mounting plate 2 6 respectively; three circulating water pipes are arranged in each of the two circulating water cooling splints 3; the two circulating water cooling splints 3 are in contact with each other, and a groove 4 is opened on the facing sides of the two circulating water cooling splints 3, and the two grooves 4 together form a steel belt channel; three acoustic sensors 7 are equidistantly arranged on the mounting plate 2 6; the bottom plate 1 is fixedly connected to the circulating water cooling jacket 9, and six circulating water pipes are arranged in the circulating water cooling jacket 9, the interior of the circulating water cooling jacket 9 is arranged to be hollow, and an air pipe is connected to the middle of the circulating water cooling jacket 9.

[0021] It also includes a mounting plate three 12; two mounting plates three 12 are connected to the power unit; the two mounting plates three 12 are slidingly connected to the left and right sides of the circulating water cooling jacket 9 respectively; a steel belt channel is formed between the middle part of the lower side of the two mounting plates three 12 and the circulating water cooling jacket 9, and the steel belt channel on the right is connected to the steel belt channel formed by the two grooves 4.

[0022] The power unit includes a cylinder one 5, a cylinder two 10, a mounting frame 11 and a cylinder three 8; two cylinders one 5 are fixedly connected to the base plate 1; the telescopic ends of the two cylinders one 5 are fixedly connected to the mounting plate two 6; a cylinder two 10 is fixedly connected to the base plate 1; the mounting frame 11 is fixedly connected to the telescopic end of the cylinder two 10; the left and right parts of the mounting frame 11 are respectively fixedly connected to a mounting plate three 12; two cylinders three 8 are fixedly connected to the base plate 1; the telescopic ends of the two cylinders three 8 are fixedly connected to the mounting plate one 2.

[0023] The first step: when in use, a steel belt traction device is set on the left side of the bottom plate 1, and the quenched steel belt is manually passed through the steel belt channel composed of two circulating water cooling splints 3 and the circulating water cooling jacket 9 in turn, and the end of the steel belt is fixed on the steel belt traction device. The steel belt channel composed of the two circulating water cooling splints 3 and the steel belt channel composed of the middle part of the lower side of the two mounting plates three 12 and the circulating water cooling jacket 9 allow the steel belt to pass smoothly, and make the steel belt contact with the two circulating water cooling splints 3, the middle part of the lower side of the two mounting plates three 12 and the end of the circulating water cooling jacket 9.

[0024] The second step: control the steel belt traction equipment to drive the steel belt to move to the left, so that the steel belt passes between the two circulating water cooling clamps 3 and the circulating water cooling jacket 9. When passing through, cooling water is introduced into the circulating water pipes in the two circulating water cooling clamps 3 and the circulating water cooling jacket 9 to cool the steel belt: first, the two circulating water cooling clamps 3 directly contact the steel belt, and then the circulating water cooling jacket 9 cools the steel belt; and through the air pipe in the middle of the circulating water cooling jacket 9, a protective gas with a lower density than air (such as argon) is introduced into the circulating water cooling jacket 9 to isolate the air and prevent the steel belt from contacting with oxygen in the air during the cooling process and causing oxidation reaction and turning yellow.

[0025] If there are defects such as cracks and pores inside the steel belt, when the two circulating water cooling clamps 3 directly contact and cool the steel belt, large thermal stress may be generated inside the steel belt, causing it to crack. When the steel belt cracks, debris may be generated, and the debris will remain between the steel belt and the circulating water cooling clamp 3. When the steel belt is pulled later, the debris and the steel belt will rub against each other, and the debris will scratch the steel belt, affecting the quality of the steel belt. Therefore, when the steel belt cracks, the steel belt will make a sound, and the characteristic frequency of the sound of the steel belt cracking will be detected by the sound sensor 7, and then the steel belt conveying will be stopped first, and then the cylinder 1 5 will be controlled to drive the mounting plate 2 6 and the upper circulating water cooling clamp 3 to move. The circulating water cooling splint 3 moves upward to separate from the steel belt, and at the same time, the control cylinder three 8 drives the mounting plate 2 and the circulating water cooling splint 3 below to move downward to separate from the steel belt. In this way, the debris will not be stuck between the steel belt and the circulating water cooling splint 3, but will fall on the steel belt or the circulating water cooling splint 3 below. Then the steel belt traction equipment will traction the cracked steel belt. During traction, the debris can be prevented from scratching the steel belt and affecting the quality of the steel belt. The cracked part of the steel belt is pulled to the left of the circulating water cooling jacket 9, the cracked part is repaired or cut off, and then the steel belt is traction again for quenching and cooling operations.

[0026] When the cracked part of the steel belt passes between the middle part of the lower side of the two mounting plates three 12 and the end of the circulating water cooling jacket 9, it will be compressed by the mounting plates three 12 and the circulating water cooling jacket 9, and the fragile steel belt will be easily cracked again. The cracked steel belt may remain in the circulating water cooling jacket 9, and it is necessary to manually remove the cracked steel belt, which increases the work intensity; therefore, before pulling the cracked steel belt out, the control cylinder two 10 drives the mounting frame 11 and the mounting plate three 12 to move upward and separate from the steel belt, so that it is convenient to pull out the cracked steel belt, and the steel belt will not be compressed when moving, which prevents the fragile steel belt from cracking again and increases the work intensity.

[0027] Example 2 On the basis of Example 1, Figure 6-Figure 8 As shown, it also includes an air frame 1 21, an air frame 23 and a baffle 24; the left part of the mounting plate 2 6 and the left part of the upper circulating water cooling clamp 3 are penetrated by the air frame 1 21; the left part of the circulating water cooling jacket 9 is fixedly connected to the baffle 24; the baffle 24 is penetrated by the air frame 23.

[0028] It also includes a baffle 22; two baffles 22 are fixedly connected to the bottom plate 1, and the two baffles 22 are symmetrically arranged front and back; the two baffles 22 are in contact with the two circulating water cooling clamps 3; the two baffles 22 are in contact with the right mounting plate 3 12.

[0029] It also includes an electric push rod 1 31 and a baffle 2 32; two electric push rods 1 31 are fixedly connected to the left part of the mounting plate 2 6; the telescopic ends of all the electric push rods 1 31 are commonly fixedly connected to the baffle 2 32, and the baffle 2 32 is located on the right side of the air frame 1 21; the baffle 2 32 is slidably connected to the mounting plate 2 6; the baffle 2 32 is slidably connected to the circulating water cooling clamp 3 above.

[0030] It also includes a baffle plate 33 ; the baffle plate 33 is welded inside the baffle frame 24 , and the baffle plate 33 is located on the left side of the air frame 23 .

[0031] When the air cylinder 2 10 is controlled to drive the mounting frame 11 and the mounting plate 3 12 to move upward and separate from the steel strip, and then the cracked steel strip is pulled out, the protective gas in the circulating water cooling jacket 9 will overflow from the gap between the circulating water cooling jacket 9 and the mounting plate 3 12 to the outside, causing air pollution; therefore, an air frame 1 21 and an air frame 2 23 are arranged on the side of the gap between the circulating water cooling jacket 9 and the mounting plate 3 12, and the air frame 2 23 is connected to the gas collector, and a protective gas with a density smaller than that of air is selected, and the overflowed protective gas will float upward into the air frame 1 21 and the air frame 23, and then enter the collector through the air frame 1 21 and the air frame 23 for collection, so as to prevent the protective gas from overflowing to the outside and causing air pollution.

[0032] In order to allow the protective gas overflowing from the gap between the circulating water cooling jacket 9 and the right mounting plate three 12 to enter the air frame one 21, a baffle two 32 is arranged on the right side of the air frame one 21, and two baffles one 22 are arranged to contact the two circulating water cooling clamps 3. After the two circulating water cooling clamps 3 are separated from the steel belt, the two baffles one 22 are still in contact with the two circulating water cooling clamps 3, so that the two baffles one 22 block the front and rear of the air frame one 21, and when the control cylinder two 10 drives the mounting frame 11 and the mounting plate three 12 to move upward and separate from the steel belt, the electric push rod one 31 is controlled to drive the baffle two 32 to descend, so that the baffle two 32 descends to contact the steel belt, and the baffle two 32 blocks the air frame In order to allow the protective gas overflowing from the gap between the circulating water cooling jacket 9 and the left mounting plate three 12 to enter the air frame two 23, a baffle frame 24 and a baffle three 33 are arranged on the left part of the circulating water cooling jacket 9, with the baffle frame 24 blocking the front and rear of the air frame two 23, and the baffle three 33 blocking the left side of the air frame two 23, so that the protective gas overflowing from the gap between the circulating water cooling jacket 9 and the left mounting plate three 12 can enter the air frame two 23, preventing the protective gas from overflowing to the outside and causing air pollution.

[0033] Example 3 On the basis of Example 2, Figure 6 and 9 picture- Fig.10 As shown, it also includes an air frame three 41; the left part of the mounting plate 2 and the left part of the circulating water cooling clamping plate 3 below are penetrated by the air frame three 41.

[0034] The right side of the baffle 1 22 is flush with the right side of the circulating water cooling clamping plate 3.

[0035] It also includes an electric push rod 2 42 and a baffle 43; two electric push rods 2 42 are fixedly connected to the right part of the mounting plate 2 6; and the telescopic ends of all the electric push rods 2 42 are fixedly connected to the baffle 43.

[0036] In order to facilitate the diversion of debris to the side, the left side of the baffle plate 43 is set to be conical.

[0037] Subsequently, the two circulating water cooling clamps 3 are controlled to contact each other, the lower side of the mounting plate three 12 is controlled to contact the circulating water cooling jacket 9, and the electric push rod one 31 is controlled to drive the baffle two 32 to move up and reset, so as to perform the steel belt cooling operation again. However, when the steel belt moves, the debris falling on the circulating water cooling clamp plate 3 below will rub the steel belt, which is easy to scratch the steel belt and affect the quality of the steel belt. Therefore, it is necessary to clean up the debris on the circulating water cooling clamp plate 3 below; therefore, first control the lower side of the mounting plate three 12 to contact the circulating water cooling jacket 9, control the electric push rod one 31 to drive the baffle two 32 to move up and reset, at this time the two circulating water cooling clamp plates 3 are still in a separated state, so that a closed chamber is formed between the two circulating water cooling clamp plates 3, the circulating water cooling jacket 9, the right mounting plate three 12 and the two baffles one 22, and only the right part is connected to the outside world, and then the air frame is cooled through the air pipe. One 21 and air frame three 41 are connected to an external air pump, the external air pump is started, and the high-pressure gas is passed into the closed chamber through air frame one 21 and air frame three 41. The high-pressure gas can only be discharged from the right part of the closed chamber. When discharged, all the debris on the circulating water cooling clamping plate 3 below is blown away, so the debris is quickly and thoroughly cleaned up; then the two circulating water cooling clamping plates 3 are controlled to contact each other to clamp the steel belt to perform the steel belt cooling operation again; a valve is set on the air pipe connecting air frame one 21 and the external air pump and on the air pipe connecting air frame three 41 and the external air pump. When cooling the steel belt, the valve is closed to prevent air from contacting the cooling steel belt through air frame one 21 and air frame three 41, causing oxidation of the steel belt; when collecting the protective gas through air frame one 21, the air pipe is connected to the gas collector so that air frame one 21 is connected to the gas collector.

[0038] When the control baffle plate 2 32 is lowered to contact the steel belt, the baffle plate 2 32 is blocked on the right side of the air frame 1 21 to ensure that the protective gas overflowing from the gap between the circulating water cooling jacket 9 and the right mounting plate 3 12 can enter the air frame 1 21. The baffle plate 2 32 can also block the debris on the steel belt when the steel belt moves, preventing the debris on the steel belt from passing through the circulating water cooling jacket in the process of pulling the cracked part of the steel belt to the left side of the circulating water cooling jacket 9 (to repair or cut the cracked part). 9 falls into it, avoiding the need to clean the debris in the circulating water cooling jacket 9 later; the debris on the steel belt is blocked on the right by the baffle plate 2 32, and then the external air pump passes the high-pressure gas into the closed chamber through the air frame 1 21 and the air frame 3 41, and the high-pressure gas blows out the debris on the steel belt; the electric push rod 2 42 is controlled in advance to drive the baffle plate 4 43 to move down and contact the steel belt. After the debris on the steel belt is blown over, it contacts the baffle plate 4 43, and then is guided to the side, separated from the steel belt, and the cleaning is completed.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
