Description

Technical Field

[0001] This invention relates to the technical field of chemical equipment, and in particular to a chemical safety treatment device and method. Background Technology

[0002] Waste gases generated during chemical production contain various harmful substances and require purification treatment. A common method involves passing the waste gas into a treatment liquid, where stirring ensures thorough contact between the gas and the liquid, utilizing chemical reactions or physical absorption to remove harmful components. The treated gas then undergoes dehydration and adsorption processes before being discharged in compliance with standards.

[0003] In existing technologies, devices typically use a fixed-position stirring shaft for rotational mixing. The stirring blades rotate only in one fixed position, limiting the mixing range. The liquid at the edges of the treatment tank cannot be fully agitated, resulting in uneven contact between the exhaust gas and the liquid, and thus, impeding improved mixing efficiency. Exhaust gas is usually introduced into the liquid from a fixed position, while the stirring mechanism operates from another fixed position. The exhaust gas outlet is not aligned with the area of ​​intense mixing, preventing the exhaust gas from contacting the liquid in the most thoroughly mixed area, thus affecting gas-liquid mixing efficiency. In existing devices, after the exhaust gas is introduced into the liquid, mixing relies solely on the stirring of the blades. The internal gas pressure in the treatment tank remains essentially constant, lacking a mechanical mechanism to dynamically adjust the internal pressure to enhance gas-liquid contact. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the above-mentioned chemical safety handling equipment and methods, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a chemical safety treatment device and method, the purpose of which is to improve treatment efficiency.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a processing box, a moving mechanism disposed inside the processing box, a stirring mechanism disposed at the bottom of the moving mechanism, a limiting mechanism slidably connected to the bottom of the stirring mechanism, a pressure plate slidably connected inside the processing box, a liquid storage tank disposed on one side of the processing box, and a control center fixedly disposed on the top of the liquid storage tank.

[0008] As a preferred embodiment of the chemical safety treatment equipment and method of the present invention, the treatment box is provided with liquid inlets on both sides, and an air outlet is opened on one side of the treatment box. Multiple sets of air outlet arrays are provided, and air inlet pipes are provided on both sides of the bottom of the treatment box.

[0009] In a preferred embodiment of the chemical safety treatment equipment and method of the present invention, the moving mechanism includes a pressure plate, a pressure rod fixedly connected to the bottom of the pressure plate, and a return spring provided at the bottom of the pressure plate.

[0010] In a preferred embodiment of the chemical safety treatment equipment and method of the present invention, the bottom of the pressure rod is connected to a first hinge block, and the bottom of the first hinge block is fixedly provided with an installation sleeve.

[0011] In a preferred embodiment of the chemical safety processing equipment and method of the present invention, the stirring mechanism includes a motor, and a stirring shaft is provided at the bottom of the motor. Multiple sets of stirring rods are arranged in a circular array on the outer side of the stirring shaft.

[0012] In a preferred embodiment of the chemical safety treatment equipment and method of the present invention, a second hinge block is connected to the bottom of the stirring shaft, and a pressing block is provided at the bottom of the second hinge block.

[0013] As a preferred embodiment of the chemical safety treatment equipment and method of the present invention, the bottom of the extrusion block is provided with multiple sets of air inlet slots, and the two sides of the extrusion block are provided with air outlet holes, which are connected to the air inlet slots.

[0014] As a preferred embodiment of the chemical safety treatment equipment and method of the present invention, the limiting mechanism includes a limiting plate, the bottom of the limiting plate is connected to an air outlet plate, the air outlet plate is hollow inside and has limiting columns arranged in a circular array.

[0015] In a preferred embodiment of the chemical safety treatment equipment and method of the present invention, the top of the air outlet plate is provided with an air outlet hole, the bottom of the air outlet hole is provided with a compression spring, the top of the compression spring is provided with a sealing plate, and the top of the sealing plate is provided with a compression block.

[0016] The beneficial effects of this invention are: The motor drives the lead screw to rotate, causing the moving block to move back and forth. The magnet on the moving block magnetically attracts the extrusion block, causing it to move back and forth along the limiting plate, making the entire stirring mechanism oscillate around the hinge point. Wherever the extrusion block moves, it squeezes the extrusion ball at that position, causing the sealing plate to move downwards, opening the air outlet at that location to exhaust gas, while other air outlets remain sealed. The area of ​​intense stirring and the exhaust gas location remain consistent, ensuring that the exhaust gas finally contacts the treated liquid at the most thoroughly stirred position, significantly improving gas-liquid mixing efficiency. When the stirring mechanism oscillates, it drives the pressure rod to move up and down, which in turn drives the pressure plate to move up and down. When the pressure plate moves downwards, the inside of the treatment chamber is sealed; further downward pressure increases the internal air pressure, forcing the gas to contact the treated liquid more deeply. When the pressure plate moves upwards, the internal air pressure decreases, and exhaust gas is released through the air outlet. By dynamically adjusting the internal air pressure of the treatment chamber, the contact depth between the gas and the treated liquid is enhanced, improving the treatment effect. The sealing plate, under the action of the compression spring, tightly adheres to the inner wall of the air outlet plate, maintaining a sealed state. Only the sealing plate corresponding to the extrusion ball being squeezed by the extrusion block will move down and open the corresponding air outlet, while the other air outlets remain sealed. This "move to where you want to exhaust" design ensures precise control of exhaust gas discharge and prevents exhaust gas from escaping from areas that have not been fully stirred.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0029] Reference Figures 1-8 The present invention provides an embodiment, specifically a chemical safety treatment device and method.

[0030] Specifically: a processing tank 1, a moving mechanism 2 located inside the processing tank 1, a stirring mechanism 3 located at the bottom of the moving mechanism 2, a limit mechanism 4 slidably connected to the bottom of the stirring mechanism 3, a pressure plate 5 slidably connected inside the processing tank 1, a liquid storage tank 6 located on one side of the processing tank 1, and a control center 7 fixedly installed on the top of the liquid storage tank 6. Liquid inlets 11 are located on both sides of the processing tank 1, and an air outlet 12 is located on one side of the processing tank 1, with multiple sets of air outlets 12 arranged in an array. Air inlet pipes 13 are located on both sides of the bottom of the processing tank 1. The moving mechanism 2 includes a pressure plate 21, a pressure rod 22 fixedly connected to the bottom of the pressure plate 21, and a return spring 23 located at the bottom of the pressure plate 21. A first hinge block 24 is connected to the bottom of the pressure rod 22, and an mounting sleeve 25 is fixedly installed at the bottom of the first hinge block 24. The stirring mechanism 3 includes a motor 31, and a stirring shaft 32 is located at the bottom of the motor 31. Multiple sets of stirring rods 33 are arranged in a circular array on the outer circumference of the stirring shaft 32. A second hinge block 24 is connected to the bottom of the stirring shaft 32, and a pressing block 35 is provided at the bottom of the second hinge block 24. Multiple air inlet slots 351 are formed at the bottom of the pressing block 35, and air outlet holes 352 are formed on both sides of the pressing block 35, communicating with the air inlet slots 351. The limiting mechanism 4 includes a limiting plate 41, and an air outlet plate 42 is connected to the bottom of the limiting plate 41. The air outlet plate 42 is hollow inside and has limiting posts 421 arranged in a circular array. An air outlet hole 422 is formed at the top of the air outlet plate 42, a compression spring 423 is provided at the bottom of the air outlet hole 422, a sealing plate 424 is provided at the top of the compression spring 423, and a pressing block 425 is provided at the top of the sealing plate 424.

[0031] When the staff uses this device, the treatment liquid in the storage tank 6 enters the interior of the treatment tank 1 through the inlet 11, and the chemical waste gas to be treated is input into the outlet plate 42 through the air inlet pipe 13. At this time, the sealing plate 424 is tightly attached to the inner wall of the outlet plate 42 under the action of the compression spring 423, thereby maintaining a seal.

[0032] The motor 31 is started to drive the stirring shaft 32 to rotate, so that the stirring shaft 32 and the stirring rod 33 rotate synchronously, thereby stirring the internal treatment liquid; It should be noted that the stirring rod 33 and the second hinge block 34 are rotatably connected, so when the stirring rod 33 rotates, the second hinge block 34 will not rotate.

[0033] The motor drives the lead screw 81 to rotate, which in turn drives the moving block 82 to move back and forth. The stability of the movement is ensured by the action of the limiting rod 84. Due to the magnetic attraction between the magnet block 83 and the extrusion block 35, the extrusion block 35 is driven to move. The extrusion block 35 also moves along the limiting plate 41, so the stirring mechanism 3 also swings back and forth, thus oscillating while stirring, which enhances the mixing effect.

[0034] When the stirring mechanism 3 swings, the pressure rod 22 also moves up and down, causing the pressure plate 21 to move back and forth. The return spring 23 ensures that it can reset itself. Since the pressure rod 22 and the air pressure plate 5 move up and down synchronously, when the air pressure plate 5 moves down, the air outlet 12 is on the air pressure plate 5, so the inside of the treatment box 1 is sealed. When it continues to press down, the internal air is pressurized. When the air pressure plate 5 moves up, the air pressure decreases and is exhausted through the air outlet 12; thereby enhancing the contact between the air and the treatment liquid.

[0035] Preferably, the extrusion block 35 extrudes the extrusion ball 425, thereby causing the sealing plate 424 to move downward, so that the internal air is discharged through the corresponding air outlet 422, while the other air outlets remain sealed. When the extrusion block 35 moves to the next location, the sealing plate 424 and the extrusion ball 425 are reset under the action of the compression spring 423. Thus, wherever the extrusion block 35 moves, exhaust begins, thereby aligning the mixing position with the exhaust position and improving mixing efficiency.

[0036] Summary: In operation, the treatment liquid in the storage tank 6 enters the treatment tank 1 through the inlet 11. Chemical waste gas is introduced into the outlet plate 42 through the inlet pipe 13. The sealing plate 424, under the action of the compression spring 423, tightly adheres to the inner wall of the outlet plate 42 to maintain a seal. The motor 31 is started, driving the stirring shaft 32 and stirring rod 33 to rotate synchronously and agitate the treatment liquid. The motor drives the lead screw 81 to rotate, causing the moving block 82 to move reciprocally. The magnet 83 on the moving block 82 magnetically attracts the extrusion block 35, causing the extrusion block 35 to move reciprocally along the limiting plate 41, making the stirring mechanism 3 oscillate reciprocally around the hinge point. When the extrusion block 35 moves, it extrudes the extrusion ball 425 at the corresponding position, causing the sealing plate 424 to move downwards and open the outlet vent 422 to exhaust air; the other outlet vents remain sealed. When the stirring mechanism 3 swings, it drives the pressure rod 22 and the pressure plate 21 to move up and down repeatedly. When the pressure plate 21 moves down, the inside of the processing box 1 is sealed and pressurized. When the pressure plate 21 moves up, the air is exhausted through the air outlet 12.
