Description

Technical Field

[0001] This utility model belongs to the field of hot-rolled coil cooling technology, and specifically relates to a segmented spray cooling device for stainless steel hot-rolled coils. Background Technology

[0002] In the production process of hot-rolled steel coils, the cooling process is one of the key links affecting product quality. If the cooling is uneven or the cooling efficiency is insufficient, it is easy to cause a temperature gradient inside the steel coil, which will affect its shape, dimensional accuracy and mechanical properties. Moreover, most existing technologies do not recycle the residual water after cooling, which can easily lead to a large consumption of water resources and increase production costs.

[0003] A search revealed that existing technology announcement number CN 216606673 U describes a water-cooling device for hot-rolled coils, comprising a housing. Slide rails are fixedly connected to both sides of the housing's interior. A slider is slidably engaged on one side of each slide rail, and a crank is fixedly connected to one side of each slider. Two sleeves are fitted onto the outer walls of the crank. A nozzle is fixedly connected to the front of each sleeve. A flexible hose is connected to the top of each nozzle. A bent pipe extending through one side of the housing is connected to the top of the flexible hose. A water pump is connected to the bottom of the bent pipe. The input end of the water pump is connected to a first water tank fixedly connected to the bottom of the housing. This device does not adequately cool the inner surface of the hot-rolled coil, which can easily lead to a temperature gradient during cooling, thus affecting the product's shape, dimensional accuracy, and mechanical properties.

[0004] Further search revealed that the existing technology announcement number is CN 218108870 U, which describes an online internal and external water spray cooling device for hot-rolled wide-band austenitic stainless steel coils. This device includes a support frame, a guiding mechanism, a power mechanism, an inner wall cooling mechanism, water tank I, water tank II, a conveyor roller, and an outer wall cooling mechanism. A pair of support frames are provided. Both ends of the conveyor roller are connected to the support frame via bearings. The guiding mechanism is located on the conveyor roller, and the power mechanism is located on one side of the support frame. The inner wall cooling mechanism is connected to the power mechanism. Several sets of outer wall cooling mechanisms are evenly installed on the support frame. Water tank I is located in the middle of the support frame and below the conveyor roller and the guiding mechanism. Water tank II is located on one side of the support frame, below the power mechanism, and one end of the inner wall cooling mechanism is located inside water tank II. Water tank I and water tank II are connected. This device does not recycle the residual water after cooling, which easily leads to a large consumption of water resources and increases production costs. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a segmented spray cooling device for stainless steel hot-rolled coils. This device enables the recycling of residual water after cooling, avoiding waste of water resources and reducing production costs. The limiting mechanism effectively prevents the stainless steel hot-rolled coils from shifting during transportation, thus preventing them from being cooled evenly and comprehensively.

The center of the disc branch pipe corresponds to the middle position of the conveyor roller. A pressure-boosting nozzle is installed on the disc branch pipe. The pressure-boosting nozzle is tilted in all directions so that the cooling water sprayed by the pressure-boosting nozzle comes into contact with the inner wall of the stainless steel hot-rolled coil, rather than passing through the inside of the stainless steel hot-rolled coil. The internal spraying mechanism has two sets, which are mirror-installed on both sides of the shell. The two sets of pressure-boosting nozzles and connecting pipes are mirror-installed to ensure that one set of internal spraying mechanism cools the inner wall of the stainless steel hot-rolled coil from the front end, and the other set cools it from the rear end of the stainless steel hot-rolled coil.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1) Excess cooling water generated during cooling flows into the water channel through the baffle. The filter plate in the water channel separates impurities from the cooling water. The cooling water flows into the buffer zone through the filter plate. The cooling water in the buffer zone enters the indirect cooling unit through the water pipe for cooling. The cooled water enters the water storage area through the water pipe, realizing the recycling of the residual water after cooling, avoiding the waste of water resources, and thus reducing production costs.

[0014] 2) Two sets of limiting blocks are set up, mirror images of each other on the transport rollers. The limiting blocks are slidably connected to the transport rollers. A bidirectional lead screw I is provided at the bottom of the limiting blocks. The bidirectional lead screw I is threadedly connected to the limiting blocks. The bidirectional lead screw I is mounted on the housing through bearings. A motor II is provided at one end of the bidirectional lead screw I. The output end of the motor II is fixedly connected to the bidirectional lead screw I. The motor II is fixedly mounted on the side wall of the housing. The motor II rotates the bidirectional lead screw I, causing the two sets of limiting blocks to move relative to each other on the transport rollers. This allows the limiting mechanism to adapt to stainless steel hot-rolled coils of different sizes, ensuring that the stainless steel hot-rolled coils are always in the middle position on the transport rollers during transportation.

[0015] 3) Motor III rotates the bidirectional lead screw II to move the sliding rod along the support rod, thereby adjusting the distance between the side spray branch pipe and the side wall of the stainless steel hot-rolled coil, ensuring that the cooling water sprayed from the side spray branch pipe is sprayed evenly onto the side wall of the stainless steel hot-rolled coil; the water in the water storage area enters the main pipe through the self-priming pump, and the water in the main pipe enters the upper spray branch pipe, lower spray branch pipe and side spray branch pipe, and finally sprays out from the nozzles of each branch pipe, ensuring that the cooling water can be evenly sprayed onto all parts of the outer wall of the stainless steel hot-rolled coil, avoiding uneven local cooling.

[0024] To facilitate understanding by those skilled in the art, the following is a detailed explanation in conjunction with the appendix. Figure 1-7 The technical solution of this utility model will be further described in detail below.

[0025] A segmented spray cooling device for hot-rolled stainless steel coils includes a shell 1, a water channel 104, a filter plate 106, and a partition-type cooler 107; a transport mechanism 2, a limiting mechanism 3, and an inner spray mechanism 5; the transport mechanism 2 is mounted on the shell 1, the limiting mechanism 3 is located on the transport roller 21, an outer spray mechanism 4 is provided at the top of the transport mechanism 2 and is fixedly installed at one end of the shell 1, and two sets of inner spray mechanisms 5 are provided, mirror-mounted on both sides of the shell 1; a baffle 105 is provided at the bottom of the transport mechanism 2. Two sets of baffles 105 are arranged in a mirror image. Each baffle 105 has an inclined angle. The top of each baffle 105 is fixedly connected to the housing 1, and the bottom of each baffle 105 is fixedly connected to the water channel 104. The bottom of the water channel 104 is provided with a buffer zone 101, a cooling zone 102, and a water storage zone 103. Filter plates 106 are installed on both sides of the water channel 104 at the top of the buffer zone 101. A partition-type cooler 107 is installed in the cooling zone 102. The partition-type cooler 107 is connected to the buffer zone 101 and the water storage zone 103 via water pipes. Cooler 107 is a BR0.65 plate heat exchanger, obtained through purchase or custom order. During operation, the distance of the limiting mechanism 3 is adjusted according to the dimensions of the stainless steel hot-rolled coil 6 to prevent positional shift during transport, maintaining it in the center position of the transport roller 21. When the stainless steel hot-rolled coil 6 reaches the bottom of the outer spray mechanism 4, the outer spray mechanism 4 sprays water onto the outer wall of the stainless steel hot-rolled coil 6 to cool it. The stainless steel hot-rolled coil 6 is then transported to the inner spray mechanism 5. During the cooling process, the inner spray mechanism 5 cools the inner wall of the stainless steel hot-rolled coil 6; the excess cooling water generated by the outer spray mechanism 4 and the inner spray mechanism 5 during the cooling of the stainless steel hot-rolled coil 6 flows into the water channel 104 through the baffle 105. The filter plate 106 in the water channel 104 separates the impurities in the water from the cooling water. The cooling water flows into the buffer zone 101 through the filter plate 106. The cooling water in the buffer zone 101 enters the partition wall cooler 107 through the water pipe for cooling. The cooled water enters the water storage zone 103 through the water pipe.

[0026] The transport mechanism 2 includes a transport roller 21; a plurality of transport rollers 21 are provided and are evenly installed on the housing 1 by bearings. One end of the transport roller 21 is provided with a motor I 22, which is fixedly installed on the side wall of the housing 1.

[0027] The limiting mechanism 3 includes limiting blocks 33; the limiting blocks 33 are configured in two sets, mirror-image arranged on the transport roller 21, the limiting blocks 33 are slidably connected to the transport roller 21, the bottom of the limiting blocks 33 is provided with a bidirectional lead screw I 32, the bidirectional lead screw I 32 is threadedly connected to the limiting blocks 33, the bidirectional lead screw I 32 is mounted on the housing 1 through bearings, one end of the bidirectional lead screw I 32 is provided with a motor II 31, the output end of the motor II 31 is fixedly connected to the bidirectional lead screw I 32, the motor II 31 is fixedly mounted on the side wall of the housing 1; the motor II 31 rotates the bidirectional lead screw I 32, so that the two sets of limiting blocks 33 move relative to each other on the transport roller 21, so that the limiting mechanism 3 can adapt to stainless steel hot-rolled coils 6 of different sizes, and ensure that the stainless steel hot-rolled coils 6 are always in the middle position of the transport roller 21 during transportation.

[0028] The external spraying mechanism 4 includes a bidirectional lead screw II 42, an upper spraying branch pipe 44, a lower spraying branch pipe 45, a main pipe 46, a connecting pipe 410, a nozzle 411, and a sliding rod 412. The main pipe 46 is installed on both sides of the housing 1, and the bottom of the main pipe 46 is connected to a water storage area 103. Water from the water storage area 103 enters the main pipe 46 through a self-priming pump. Both ends of the upper spraying branch pipe 44 and the lower spraying branch pipe 45 are equipped with flanges 47, which connect to the main pipe 46 via the flanges 47 and are fixed to the inner wall of the housing 1. The top of the housing 1 is provided with a support rod 43, which is fixedly connected to the housing 1. The support rod 43 is provided with a sliding groove I 48, which is "T" shaped. One end of the sliding rod 412 is located in the sliding groove I 48 and is slidably connected to the support rod 43. One end of the sliding rod 412 is "T" shaped and matches the sliding groove I 48. The bottom of the sliding rod 412 is provided with a side spray branch pipe 49, which is fixedly connected to the sliding rod 412. A connecting pipe 410 is fixedly connected to one side of the side spray branch pipe 49, and the connecting pipe 410 is inserted into the main pipe 46. The bidirectional lead screw II 42 is located at the bottom of the support rod 43, and is rotatably connected to the housing 1 and threadedly connected to the sliding rod 412. A motor III 41 is mounted at one end of the bidirectional lead screw II 42, and the motor III 41 is fixedly installed on the side wall of the housing 1. Several nozzles 411 are provided on the upper spray branch pipe 44, lower spray branch pipe 45, and side spray branch pipe 49. This allows for sufficient cooling of the outer surface of the stainless steel hot-rolled coil 6. During operation, the motor III 41 rotates the bidirectional lead screw II 42, causing the sliding rod 412 to slide along the support rod 43. This adjusts the distance between the side spray branch pipe 49 and the side wall of the stainless steel hot-rolled coil 6, ensuring that the cooling water sprayed from the side spray branch pipe 49 is sprayed evenly onto the side wall of the stainless steel hot-rolled coil 6. The water in the water storage area 103 enters the main pipe 46 through a self-priming pump. The water in the main pipe 46 enters the upper spray branch pipe 44, the lower spray branch pipe 45, and the side spray branch pipe 49, and is finally sprayed out from the nozzles 411 of each branch pipe, ensuring that the cooling water can be evenly sprayed onto all parts of the outer wall of the stainless steel hot-rolled coil 6, avoiding uneven cooling of the outer wall of the stainless steel hot-rolled coil 6 in some areas.

[0029] The internal spraying mechanism 5 includes a water collection tank 54, a slider 56, a self-priming pump I 57, a connecting pipe 59, a disc branch pipe 510, a flexible hose 511, a self-priming pump II 512, and a booster nozzle 514. The water collection tank 54 is installed on the side wall of the housing 1, and the self-priming pump I 57 is fixedly installed on one side of the water collection tank 54. The self-priming pump I 57 is connected to the water storage area 103 at the bottom of the housing 1 through a water pipe. The top of the water collection tank 54 is provided with a reciprocating screw 51 and a guide rod 52. The reciprocating screw 51 is rotatably connected to the water collection tank 54, and the guide rod 52 is fixedly connected to the water collection tank 54. A motor IV 53 is provided at one end of the lead screw 51. The motor IV 53 is fixedly installed at one end of the water collection tank 54. The slider 56 is located on the water collection tank 54. The slider 56 is movably connected to the reciprocating lead screw 51 through a spiral groove on the reciprocating lead screw 51 and is slidably connected to the guide rod 52, realizing the movement of the slider 56 on the water collection tank 54. A groove is provided on one side of the slider 56, and a self-priming pump II 512 is installed in the groove. A suction pipe 513 is provided at the bottom of the self-priming pump II 512 and is fixedly connected to the self-priming pump II 512. A sliding groove II 55 is provided on the water collection tank 54, and one end of the suction pipe 513 passes through... The slider 56 is inserted into the slide groove II 55 to ensure that the self-priming pump II 512 can draw water from the water collection tank 54 when the slider 56 moves. A fixed seat 515 is provided on the slider 56, and a connecting seat 516 is provided at one end of the connecting pipe 59. The connecting seat 516 is rotatably connected to the fixed seat 515 via a rotating shaft. A motor V 58 is provided on the side wall of the fixed seat 515, and the output shaft of the motor V 58 is connected to the connecting seat 516 at one end of the connecting pipe 59. The connecting pipe 59 is connected to the self-priming pump II 512 via a flexible hose 511. One end of the connecting pipe 59 is connected to a disc branch pipe 510. The center of the 10 corresponds to the middle position of the transport roller 21. A pressure-boosting nozzle 514 is installed on the disc branch pipe 510. The pressure-boosting nozzle 514 is tilted in all directions so that the cooling water sprayed by the pressure-boosting nozzle 514 contacts the inner wall of the stainless steel hot-rolled coil 6, instead of passing through the inside of the stainless steel hot-rolled coil 6. The inner spraying mechanism 5 is provided in two sets, which are mirror images installed on both sides of the housing 1. The two sets of pressure-boosting nozzles 514 and connecting pipes 59 are mirror images to ensure that one set of inner spraying mechanism 5 cools the inner wall of the stainless steel hot-rolled coil 6 from the front end, and the other set cools it from the rear end of the stainless steel hot-rolled coil 6.During operation, as the stainless steel hot-rolled coil 6 is about to be transported out from the bottom of the outer spraying mechanism 4, the booster nozzle 514 operates in conjunction with the inner spraying mechanism 5 at the front end of the stainless steel hot-rolled coil 6. Motor V 58 rotates the connecting seat 516, thereby rotating the connecting pipe 59, aligning the disc branch pipe 510 with the inside of the stainless steel hot-rolled coil 6. The self-priming pump II 512 starts, drawing cooling water from the water collection tank 54 into the connecting pipe 59 through the hose 511. The cooling water then enters the disc branch pipe 510 through the connecting pipe 59 and is finally sprayed out from the booster nozzle 514 to cool the inner wall of the stainless steel hot-rolled coil 6. To prevent the stainless steel hot-rolled coil 6 from colliding with the inner spraying mechanism 5, motor IV 53 rotates the reciprocating screw 51. The slider 56 moves along the guide rod 52, and the connecting pipe 59 and the disc branch pipe 510 also move accordingly. When the slider 56 moves to one end of the water collection tank 54, the motor V 58 rotates the connecting seat 516, which drives the disc branch pipe 510 to rotate above the slider 56 to avoid collision with the stainless steel hot-rolled coil 6. The motor IV 53 rotates the reciprocating screw 51, causing the slider 56 to return to its initial position along the guide rod 52. When the stainless steel hot-rolled coil 6 completely leaves the outer spray mechanism 4, the pressurized nozzle 514 corresponds to the inner spray mechanism 5 at the rear end of the stainless steel hot-rolled coil 6 to cool the inner wall of the stainless steel hot-rolled coil 6 from the rear end. The two sets of inner spray mechanisms 5 operate in the same manner.

[0030] A segmented spray cooling device for hot-rolled stainless steel coils operates as follows:

[0031] During operation, the distance of the limiting mechanism 3 is adjusted according to the dimensions of the stainless steel hot-rolled coil 6, so that the stainless steel hot-rolled coil 6 is kept in the middle position of the transport roller 21 during transportation. When the stainless steel hot-rolled coil 6 is transported to the bottom of the outer spraying mechanism 4, the nozzles 411 on the upper spraying branch pipe 44, lower spraying branch pipe 45 and side spraying branch pipe 49 spray water to cool the outside of the stainless steel hot-rolled coil 6. The motor III 41 rotates the bidirectional lead screw II 42 to move the sliding rod 412 along the support rod 43, thereby adjusting the distance between the side spraying branch pipe 49 and the side wall of the stainless steel hot-rolled coil 6, ensuring that the cooling water sprayed from the side spraying branch pipe 49 is evenly distributed. The water is sprayed onto the side wall of the stainless steel hot-rolled coil 6. When the stainless steel hot-rolled coil 6 is transported to the front of the inner spraying mechanism 5, the disc branch pipe 510 sprays water onto the inner wall of the stainless steel hot-rolled coil 6 through the pressurized nozzle 514, so that the inside of the stainless steel hot-rolled coil 6 is cooled. At the same time, the excess cooling water generated during cooling flows into the water channel 104 through the baffle 105. The filter plate 106 in the water channel 104 separates the impurities in the water from the cooling water. The cooling water flows into the buffer zone 101 through the filter plate 106. The cooling water in the buffer zone 101 enters the partition cooler 107 through the water pipe for cooling. The cooled water enters the water storage zone 103 through the water pipe.
