Description

Technical Field

[0001] This application relates to the field of steel product processing, and in particular to a steel pickling tank. Background Technology

[0002] Steel pickling refers to the process of creating a clean and active surface on steel strips to ensure the surface quality of the produced steel. This process removes surface iron oxide scale, facilitating subsequent deep processing. Various iron oxides in the iron oxide scale on the steel surface react chemically with acid to form water-soluble iron salts that dissolve in the acid solution.

[0003] In related technologies, a steel pickling tank includes a pickling tank, a placement plate, and a filter plate. An outlet is provided on the side wall at the bottom of the pickling tank, and an outlet pipe connected to the outlet is fixedly connected to the side wall at the bottom of the pickling tank. The top of the pickling tank is open, and a cover plate is hinged to the top of the pickling tank. The size of the cover plate is the same as the size of the opening at the top of the pickling tank, and the cover plate can close the pickling tank. The placement plate is fixedly connected to the inner wall of the pickling tank, and the steel is placed on the placement plate for pickling. The filter plate is fixedly connected to the inner wall of the pickling tank and located below the placement plate. The filter plate can filter the waste in the pickling tank, preventing waste from accumulating at the bottom of the pickling tank.

[0004] Regarding the aforementioned technologies, during the pickling process of steel, the reaction causes the acid concentration to vary at different locations in the pickling tank, resulting in incomplete removal of rust spots from the steel and thus poor pickling effect. Summary of the Invention

[0005] To improve the poor pickling effect of steel, this application provides a steel pickling tank.

[0006] The steel pickling tank provided in this application adopts the following technical solution:

[0007] A steel pickling tank includes a pickling tank, in which a vibrating plate is horizontally placed. A support plate for supporting the steel is fixedly connected to the vibrating plate. Two sets of vibrating components for driving the vibrating plate to move up and down are installed in the pickling tank. The two sets of vibrating components are located on both sides of the vibrating plate. Installation grooves are provided on the inner walls of both sides of the pickling tank.

[0008] The vibrating component includes a motor fixedly connected to the side wall of the pickling tank, a reciprocating screw rotatably mounted on the inner wall of the mounting groove, a guide rod fixedly connected to the inner wall of the mounting groove, and a vibrating block sleeved on the reciprocating screw and the guide rod. The reciprocating screw and the guide rod are parallel and both are vertically arranged. A first bevel gear is fixedly connected to the output shaft of the motor, and a second bevel gear meshing with the first bevel gear is fixedly connected to the reciprocating screw. The vibrating block is threadedly connected to the reciprocating screw and is placed below the vibrating plate and in contact with the vibrating plate.

[0009] By adopting the above technical solution, the motor is started, which drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate, which drives the reciprocating screw to rotate. The reciprocating screw drives the vibrating block to move back and forth, which drives the vibrating plate to move back and forth. The vibrating plate drives the support plate to move up and down, and the support plate drives the steel to move up and down. This not only makes the solution in the pickling tank evenly mixed, but also ensures that the steel is in full contact with the pickling solution, thus improving the problem of poor pickling effect of steel.

[0010] Preferably, the bottom of the vibrating plate is provided with a snap-fit ​​groove with an open side, the vibrating block is placed in the snap-fit ​​groove, and the inner wall of the snap-fit ​​groove is in contact with the side wall of the vibrating block.

[0011] By adopting the above technical solution, the snap-fit ​​groove is used in conjunction with the vibrating block, which improves the stability of the connection between the vibrating plate and the vibrating block.

[0012] Preferably, the pickling tank is equipped with two sets of lifting components, which are located on both sides of the vibrating plate. Each lifting component includes a lifting screw rotatably mounted on the bottom surface of the pickling tank and a lifting block sleeved on the lifting screw. The lifting screw is threadedly connected to the lifting block. The vibrating plate has a through hole for the lifting screw to pass through.

An elastic component is installed on the bottom surface of the pickling tank, which can contact the lifting block. A transmission component is installed on the pickling tank, and the motor drives the lifting screw to rotate through the transmission component.

[0013] By adopting the above technical solution, during the operation of the motor, the motor drives the lifting screw to rotate through the transmission components. When the motor rotates forward, the lifting screw drives the lifting block to move upward, the lifting block drives the vibrating plate to move upward, the vibrating plate separates from the vibrating block, the vibrating plate drives the support plate to move upward, and the support plate drives the steel to move upward, making it convenient for workers to pick up and place the steel. When the motor rotates in reverse, the lifting screw drives the lifting block to move downward, the lifting block drives the vibrating plate to move downward, when the vibrating plate contacts the vibrating block, the lifting block separates from the vibrating plate, the lifting block continues to move downward, when the lifting block moves to the smooth section on the lifting screw, the lifting block abuts against the elastic component, the lifting block stops moving, and the vibrating block continues to drive the vibrating plate to shake, so that the steel is pickled, which is convenient for workers to operate.

[0014] Preferably, the transmission component includes a transmission rod rotatably mounted on the inner wall of the pickling tank, the transmission rod extending to the outside of the pickling tank, a transmission belt sleeved on the transmission rod and the output shaft of the motor, a third bevel gear fixedly connected to the transmission rod, and a fourth bevel gear meshing with the third bevel gear fixedly connected to the lifting screw.

[0015] By adopting the above technical solution, when the motor starts, the motor drives the transmission belt to rotate, the transmission belt drives the transmission rod to rotate, the transmission rod drives the third bevel gear to rotate, the third bevel gear drives the fourth bevel gear to rotate, and the fourth bevel gear drives the lifting screw to rotate, thus reducing the number of operation steps for the staff.

[0016] Preferably, the elastic component includes a spring fixedly connected to the bottom surface of the pickling tank, the top of which can abut against the lifting block.

[0017] By adopting the above technical solution, during the downward movement of the lifting block, the lifting block abuts against the spring. When the lifting screw rotates forward, the spring pushes the lifting block to engage with the lifting screw, causing the lifting screw to drive the lifting block to move upward, without the need for operator intervention.

[0018] Preferably, baffles are fixedly connected to all four side walls of the support plate.

[0019] By adopting the above technical solution, the baffle can block the steel during the shaking of the support plate, reducing the occurrence of steel falling off the support plate.

[0020] Preferably, both the vibrating plate and the support plate are provided with multiple water-permeable holes.

[0021] By adopting the above technical solution, the contact area between the steel and the pickling solution is increased, making the pickling of the steel more thorough.

[0022] Preferably, a waste gas recovery device is provided on one side of the pickling tank, and a waste gas recovery hole is opened on the side wall at the top of the pickling tank. The waste gas recovery hole and the waste gas recovery device are connected by a waste gas recovery pipe.

[0023] By adopting the above technical solution, the waste gas generated during the pickling process of steel can enter the waste gas recovery device through the waste gas recovery hole and waste gas recovery pipe, thereby recovering the waste gas and reducing air pollution.

[0024] Preferably, multiple waste gas recovery holes are provided, and the multiple waste gas recovery holes are evenly distributed on the four inner walls of the pickling tank.

[0025] By adopting the above technical solution, the exhaust gas can enter the exhaust gas recovery device more quickly, further reducing air pollution.

[0026] Preferably, a filter is provided on one side of the pickling tank, a pump is fixedly connected to the top of the filter, a filtrate inlet is provided on the side wall at the bottom of the pickling tank, the filtrate inlet is connected to the filter through an inlet pipe, the pump is connected to the filter through a connecting pipe, and a filtrate outlet is provided on the side wall at the top of the pickling tank, the filtrate outlet is connected to the pump through an outlet pipe.

[0027] By adopting the above technical solution, when the waste accumulates at the bottom of the pickling tank, the pump is started. The pump can draw the solution in the pickling tank into the filter from the filtrate inlet and the inlet pipe, thereby filtering the pickling solution. The filtered solution enters the pickling tank from the outlet pipe and the filtrate outlet, thereby discharging the waste in the pickling tank and ensuring the pickling effect of the pickling solution.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. This application, by setting up a motor, a first bevel gear, a second bevel gear, a reciprocating screw, and a vibrating block, starts the motor, which drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the reciprocating screw to rotate, which in turn drives the vibrating block to move back and forth, which in turn drives the vibrating plate to move back and forth, which in turn drives the support plate to move up and down, which in turn drives the steel to move up and down. This not only ensures that the solution in the pickling tank is mixed evenly, but also ensures that the steel is in full contact with the pickling solution, thus improving the problem of poor pickling effect of steel.

[0030] 2. This application improves the stability of the connection between the vibrating plate and the vibrating block by setting a snap-fit ​​groove, which works in conjunction with the vibrating block;

[0031] 3. This application, by setting up a lifting screw, a lifting block, a transmission component, and an elastic component, allows the motor to drive the lifting screw to rotate during operation. When the motor rotates forward, the lifting screw drives the lifting block to move upward, which in turn drives the vibrating plate to move upward. The vibrating plate then separates from the vibrating block, and the vibrating plate drives the support plate to move upward, which in turn drives the steel to move upward, facilitating the handling and placement of the steel by the operator. When the motor rotates in reverse, the lifting screw drives the lifting block to move downward, which in turn drives the vibrating plate to move downward. When the vibrating plate contacts the vibrating block, the lifting block separates from the vibrating plate, and the lifting block continues to move downward. When the lifting block reaches the smooth section on the lifting screw, it abuts against the elastic component, stops moving, and the vibrating block continues to drive the vibrating plate to shake, thus pickling the steel and facilitating operator operation.

A support plate 12 is fixedly connected to the top of the vibrating plate 11, and baffles 121 are fixedly connected to the four sidewalls of the support plate 12. Steel can be placed on the support plate 12, and the baffles 121 can block the steel. Multiple water-permeable holes 14 are provided on both the vibrating plate 11 and the support plate 12, increasing the contact area between the steel and the pickling solution, thus ensuring more thorough pickling. The two sets of vibrating components 2, two sets of lifting components 3, two sets of elastic components 4, two sets of transmission components 5, a waste gas recovery device 6, and a filter 7 are also included.

The two sets of vibration components 2, the two sets of lifting components 3, the two sets of elastic components 4 and the two sets of transmission components 5 are all set on the two sets of the vibrating plate 11. The vibration component 2 can drive the vibrating plate 11 to move back and forth, so that the support plate 12 moves up and down, thereby driving the steel to move up and down. This can not only make the solution in the pickling tank 1 evenly mixed, but also make the steel fully contact the pickling solution, thus improving the problem of poor pickling effect of steel. The lifting component 3 can drive the vibrating plate 11 to move upward, the vibrating plate 11 drives the support plate 12 to move upward, and the support plate 12 drives the steel to move upward, making it convenient for workers to pick up and place the steel.

[0039] Reference Figure 3 and Figure 4The pickling tank 1 has vertically formed mounting grooves 13 on both sides of its inner wall. Each mounting groove 13 corresponds to a vibrating component 2. The vibrating component 2 includes a motor 21, a reciprocating screw 22, a guide rod 23, and a vibrating block 24. The motor 21 is fixedly connected to the side wall of the pickling tank 1. The output shaft of the motor 21 is horizontally positioned and rotatably mounted on the side wall of the pickling tank 1, extending into the mounting groove 13. A first bevel gear 211, fixedly connected to the output shaft of the motor 21, is fitted onto the output shaft. When the motor 21 is started, it drives the first bevel gear 211 to rotate. The reciprocating screw 22 is rotatably mounted on the inner bottom surface of the mounting groove 13 and is vertically positioned. A second bevel gear 221, fixedly connected to the reciprocating screw 22, is fitted onto the reciprocating screw 22. The second bevel gear 221 meshes with the first bevel gear 211. The first bevel gear 211 drives the second bevel gear 221 to rotate, and the second bevel gear 221 drives the reciprocating screw 22 to rotate. The guide rod 23 is fixedly connected to the inner bottom surface of the mounting groove 13 and is vertically arranged. The vibrating block 24 is sleeved on the reciprocating screw 22 and the guide rod 23 and is threadedly connected to the reciprocating screw 22. The reciprocating screw 22 drives the vibrating block 24 to move back and forth. The guide rod 23 guides the vibrating block 24. The vibrating block 24 is located below the vibrating plate 11. The bottom of the vibrating plate 11 has a snap-fit ​​groove 111 with an open side. The vibrating block 24 is placed in the snap-fit ​​groove 111. The inner wall of the snap-fit ​​groove 111 is in contact with the side wall of the vibrating block 24. The vibrating block 24 drives the vibrating plate 11 to move back and forth.

[0040] Reference Figure 3 and Figure 4The lifting component 3 includes a lifting screw 31 and a lifting block 32. The lifting screw 31 is rotatably mounted on the inner bottom surface of the pickling tank 1 and is vertically arranged. A through hole 112 is vertically opened on the end face of the vibrating plate 11 for the lifting screw 31 to pass through. During the operation of the motor 21, the motor 21 can drive the lifting screw 31 to rotate through the transmission component 5. The lifting block 32 is sleeved on the lifting screw 31 and threadedly connected to the lifting screw 31. The lifting block 32 is located below the vibrating plate 11. When the motor 21 rotates forward, the lifting screw 31 drives the lifting block 32 to move upward, and the lifting block 32 drives the vibrating plate 11 to move upward. The vibrating plate 11 and the vibrating block 24 Separation occurs when the vibrating plate 11 moves the support plate 12 upward, and the support plate 12 moves the steel upward. The bottom of the lifting screw 31 is provided with a smooth section, and the elastic component 4 is installed on the inner bottom surface of the pickling tank 1. When the motor 21 reverses, the lifting screw 31 moves the lifting block 32 downward, and the lifting block 32 moves the vibrating plate 11 downward. When the vibrating plate 11 contacts the vibrating block 24, the lifting block 32 separates from the vibrating plate 11 and continues to move downward. When the lifting block 32 moves to the smooth section on the lifting screw 31, the lifting block 32 abuts against the elastic component 4, and the lifting block 32 stops moving. The vibrating block 24 continues to drive the vibrating plate 11 to shake.

[0041] Reference Figure 3 and Figure 4 The elastic component 4 includes a spring 41, which is fixedly connected to the inner bottom surface of the pickling tank 1 and is vertically arranged. The top of the spring 41 can abut against the bottom of the lifting block 32. During the downward movement of the lifting block 32, the lifting block 32 abuts against the spring 41. When the lifting screw 31 rotates forward, the spring 41 pushes the lifting block 32 to engage with the lifting screw 31, so that the lifting screw 31 drives the lifting block 32 to move upward.

[0042] The transmission component 5 includes a transmission rod 51, a transmission belt 52, a third bevel gear 53, and a fourth bevel gear 54. The transmission rod 51 is rotatably mounted on the inner wall of the pickling tank 1 and is horizontally positioned, extending to the outer side of the pickling tank 1. The transmission belt 52 is sleeved on the output shaft of the transmission rod 51 and the motor 21. When the motor 21 starts, the motor 21 drives the transmission belt 52 to rotate, and the transmission belt 52 drives the transmission rod 51 to rotate. The third bevel gear 53 is sleeved on the transmission rod 51 and is fixedly connected to the transmission rod 51. The third bevel gear 53 is located in the pickling tank 1, and the transmission rod 51 drives the third bevel gear 53 to rotate. The fourth bevel gear 54 is sleeved on the lifting screw 31 and is fixedly connected to the lifting screw 31. The fourth bevel gear 54 meshes with the third bevel gear 53, and the third bevel gear 53 drives the fourth bevel gear 54 to rotate, which in turn drives the lifting screw 31 to rotate.

[0043] Reference Figure 1 and Figure 2 The waste gas recovery device 6 is installed on one side of the pickling tank 1. Multiple waste gas recovery holes 15 are opened on the side wall of the top of the pickling tank 1. The multiple waste gas recovery holes 15 are evenly distributed on the four inner walls of the pickling tank 1. The multiple waste gas recovery holes 15 are connected to the waste gas recovery device 6 through the waste gas recovery pipe 61. During the pickling process of steel, the waste gas generated can enter the waste gas recovery device 6 through the waste gas recovery holes 15 and the waste gas recovery pipe 61, thereby recovering the waste gas and reducing air pollution.

[0044] The filter 7 is located on the side of the pickling tank 1 away from the waste gas recovery device 6. A pump 71 is fixedly connected to the top of the filter 7. A filtrate inlet 16 is opened on the side wall at the bottom of the pickling tank 1, and a filtrate outlet 17 is opened on the side wall at the top of the pickling tank 1. The filtrate inlet 16 is connected to the filter 7 through an inlet pipe 72, the pump 71 is connected to the filter 7 through a connecting pipe 73, and the filtrate outlet 17 is connected to the pump 71 through an outlet pipe 74. When waste accumulates at the bottom of the pickling tank 1, the pump 71 is started. The pump 71 can draw the solution in the pickling tank 1 into the filter 7 through the filtrate inlet 16 and the inlet pipe 72, thereby filtering the pickling solution. The filtered solution enters the pickling tank 1 through the outlet pipe 74 and the filtrate outlet 17, thereby discharging the waste in the pickling tank 1 and ensuring the pickling effect of the pickling solution.

[0045] The implementation principle of a steel pickling tank according to an embodiment of this application is as follows: When steel needs to be pickled, the motor 21 is first started to rotate forward. The motor 21 drives the transmission belt 52 to rotate, the transmission belt 52 drives the transmission rod 51 to rotate, the transmission rod 51 drives the third bevel gear 53 to rotate, the third bevel gear 53 drives the fourth bevel gear 54 to rotate, the fourth bevel gear 54 drives the lifting screw 31 to rotate, the lifting screw 31 drives the lifting block 32 to move upward, the lifting block 32 drives the vibrating plate 11 to move upward, the vibrating plate 11 separates from the vibrating block 24, the vibrating plate 11 drives the support plate 12 to move upward, when the support plate 12 reaches the top of the pickling tank 1, the steel is placed on the support plate 12, and then the motor 21 is started to rotate in reverse, the lifting screw 31 drives the lifting block 32 to move downward. The lifting block 32 drives the vibrating plate 11 to move downwards. At the same time, the motor 21 drives the first bevel gear 211 to rotate. The first bevel gear 211 drives the second bevel gear 221 to rotate. The second bevel gear 221 drives the reciprocating screw 22 to rotate. The reciprocating screw 22 drives the vibrating block 24 to move back and forth. When the vibrating plate 11 contacts the vibrating block 24, the lifting block 32 separates from the vibrating plate 11. The lifting block 32 continues to move downwards. When the lifting block 32 moves to the smooth section on the lifting screw 31, the lifting block 32 abuts against the spring 41. The lifting block 32 stops moving. The vibrating block 24 continues to drive the vibrating plate 11 to shake. This can make the solution in the pickling tank 1 mix evenly and make the steel fully contact the pickling solution, thus improving the problem of poor pickling effect of steel.

[0046] At this time, the waste gas generated by pickling can enter the waste gas recovery device 6 through the waste gas recovery hole 15 and the waste gas recovery pipe 61 to recover the waste gas. When the waste debris accumulates at the bottom of the pickling tank 1, the pump 71 is started. The pump 71 can draw the solution in the pickling tank 1 into the filter 7 through the filtrate inlet 16 and the inlet pipe 72, thereby filtering the pickling solution. The filtered solution enters the pickling tank 1 through the outlet pipe 74 and the filtrate outlet 17, thereby discharging the waste debris in the pickling tank 1 and ensuring the pickling effect of the pickling solution.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
