Description

Technical Field

[0001] The present application belongs to the technical field of hydrogen chloride recovery, and in particular relates to an automatic recovery device for residual liquid in a steel cylinder and a control method thereof. Background Art

[0002] Liquid hydrogen chloride is generally stored in steel cylinders. After use, there will be liquid residue in the cylinders. When the cylinders are recycled after use, they are generally cleaned directly, resulting in a certain loss of hydrogen chloride.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration, such as the patent with publication number CN100593041 C, which discloses a method and system for recovering valuable resources in acidic etching waste liquid. The recovery method of the present invention comprises the following steps: adding an oxidant and concentrated sulfuric acid to the etching waste liquid; preheating and heating the above-mentioned etching waste liquid; evaporating under negative pressure to evaporate water vapor and hydrogen chloride, and recovering hydrochloric acid; centrifuging the residue to separate sulfuric acid and copper sulfate crystals, and recovering sulfuric acid; washing the copper sulfate crystals with a saturated copper sulfate solution and anhydrous ethanol to recover copper sulfate. The recovery system includes an oxidation tank, a batching tank, a preheater, a heater, an evaporator, a filter, a condenser, and a jet absorber.

[0004] The discharge effect of residual liquid in the above patent still needs to be strengthened and improved. Summary of the invention

[0005] The purpose of this application is to provide an automatic recovery device for residual liquid in a cylinder, which can solve the above-mentioned problems.

[0006] The purpose of this application is to provide an automatic recovery device for residual liquid in a steel cylinder, comprising:

[0007] Fixed frame;

[0008] A clamping mechanism, which is disposed on the fixing frame and is used to fix the inverted cylinder;

[0009] A recovery hook is arranged on the fixed frame and connected to the inverted cylinder to recover the residual liquid in the cylinder;

[0010] Wherein, the recovery mechanism includes a fixed sleeve connected to the steel cylinder, a recovery pipe arranged at the bottom of the fixed sleeve and connected to the inside of the fixed sleeve, and a pressurized liquid discharge mechanism.

[0011] The above-mentioned automatic recovery device for residual liquid in a steel cylinder can effectively increase the pressure of the residual liquid inside the steel cylinder through the pressurized liquid discharge mechanism, forcing the residual liquid to be discharged from the steel cylinder more thoroughly. Compared with the traditional method, the recovery rate and discharge efficiency of the residual liquid are greatly improved. The design of the clamping mechanism enables the inverted steel cylinder to be firmly fixed on the fixed frame, which not only ensures the stability during the recovery process, but also reduces the risk of direct contact between the operator and the residual liquid in the steel cylinder, thereby improving the safety of the operation. At the same time, the automated design reduces manual intervention and simplifies the operation process. At the same time, the clamping mechanism can be adjusted and can adapt to steel cylinders of different specifications and sizes, thereby improving the scope of application and flexibility of the device.

[0012] Furthermore, the pressurized liquid discharge mechanism includes a compressor arranged on a fixed frame and a connecting pipe connected to the compressor, and the other end of the connecting pipe is inserted into the cylinder.

[0013] The compressor is installed on the fixed frame as the power source for providing compressed gas and providing the necessary pressure difference for the subsequent drainage process. One end of the connecting pipe is tightly connected to the compressor outlet to ensure that the compressed gas can be transmitted stably and efficiently, and the other end is inserted into the clamped and inverted cylinder. When the compressor is started, the compressed gas is sent into the cylinder through the connecting pipe to assist the discharge of residual liquid and improve the drainage efficiency.

[0014] Further: the clamping mechanism comprises:

[0015] The seat body is arranged on the fixing frame and has a cavity inside;

[0016] The driving structure is arranged in the cavity and includes a cylinder and a connecting block arranged on an output shaft of the cylinder;

[0017] The fixing structure includes a first claw body and a second claw body which are arranged on both sides of the base body, and the first claw body and the second claw body are combined to form a fixing ring for fixing the cylinder;

[0018] Among them, there are two groups of clamping mechanisms, which are arranged on the fixed frame at upper and lower intervals, respectively used to fix the upper and lower parts of the cylinder, and the fixed structure is connected to the driving structure, and the driving structure drives the fixed structure to operate.

[0019] The seat body is the basic support component of the clamping mechanism and is arranged on the fixed frame. A cavity is arranged inside the seat body, which provides sufficient installation and operation space for other structures. The driving structure is located in the seat body cavity. As the power source of the clamping mechanism, it is mainly composed of a cylinder and a connecting block. The cylinder drives the output shaft to drive the connecting block to move. The fixed structure is composed of a first claw body and a second claw body, which are arranged on both sides of the seat body. When the first claw body and the second claw body are combined, they will form a complete fixed ring for clamping the cylinder to ensure that cylinders of different sizes can be firmly clamped and the stability of the cylinder can be maintained during the residual liquid recovery process.

[0020] At the same time, the clamping mechanism is set in two groups on the fixed frame, and is spaced apart from top to bottom, which can ensure that both the upper and lower parts of the cylinder can be effectively clamped, thereby further improving the stability of the cylinder during the residual liquid recovery process. The fixed structure is connected to the driving structure. When the cylinder receives a control signal and starts to telescope, the connecting block will drive the fixed structure to move accordingly, thereby realizing the clamping and releasing operations of the cylinder.

[0021] Furthermore, the fixing structure further includes:

[0022] A sliding groove is arranged on the seat body, and a sliding rail is arranged inside the sliding groove;

[0023] The sliding assembly includes a first support block and a second support block slidably disposed on the slide rail, wherein one end of the first support block and the second support block outside the sliding groove is respectively connected to the first claw body and the second claw body, and the other end extends to the inside of the seat body;

[0024] A stabilizing assembly is arranged on the base body and located on both sides of the first supporting block, and can make the sliding of the first sliding block more stable;

[0025] Wherein, a linkage component is further arranged between the first support block and the second support block, and the linkage component is used to make the first support block and the second support block operate synchronously.

[0026] The sliding groove is arranged on the seat body, and a slide rail is arranged inside the seat body. The design of the slide rail not only ensures that the sliding assembly can move smoothly in the groove, but also provides necessary guiding and supporting functions, so that the first support block and the second support block can move stably and accurately along a predetermined track when the driving structure acts on them. The sliding assembly includes a first support block and a second support block, which are respectively connected to the first claw body and the second claw body. Under the guidance of the sliding groove, the first support block and the second support block can move synchronously along the slide rail, which not only improves the accuracy and stability of the clamping action, but also enables the clamping mechanism to adapt to cylinders of different sizes, thereby improving its versatility and adaptability.

[0027] At the same time, in order to further improve the stability of the sliding assembly, a stabilizing assembly is provided on the seat body and is located on both sides of the first support block, which can provide additional support and buffering for the first support block during the sliding process, thereby preventing it from shaking or deflecting due to excessive force, and can also make the clamping work more urgent and stable. The linkage assembly is connected between the first support block and the second support block, and can achieve their synchronous operation, ensuring that they always keep in sync during the movement process, which not only improves the working efficiency of the clamping mechanism, but also makes the clamping force more uniform and stable, thereby avoiding the occurrence of tightening and loosening.

[0028] By introducing optimized designs such as sliding grooves, sliding components, stabilizing components and linkage components, the fixed structure has higher stability and reliability in the automatic recovery device for residual liquid in cylinders. The synergistic effect of these components not only improves the clamping force and accuracy of the clamping mechanism, but also makes the entire device more flexible and adaptable, meeting the safety requirements in the residual liquid recovery process.

[0029] Furthermore, the linkage assembly includes a first rack and a second rack respectively arranged on the first support block and the second support block, and a gear located between the two racks, the gear is meshed with the first rack and the second rack, and the bottom of the first support block is connected to the connecting block.

[0030] The first rack and the second rack are fixed on the first support block and the second support block respectively, and the tooth surfaces of the two are opposite. The gear is located between the first rack and the second rack and meshes with them. When the driving structure drives the first support block to move through the connecting block, the gear will synchronously drive the second support block to move in the opposite direction, thereby realizing the synchronous operation of the two. One end of the connecting block is connected to the cylinder output shaft, and the other end is connected to the bottom of the first support block. When the cylinder receives the control signal and starts to telescope, the connecting block will drive the first support block to move along the slide rail. Due to the meshing of the gear and the rack, the second support block will also synchronously move in the opposite direction, thereby completing the clamping of the cylinder.

[0031] Furthermore, the stabilizing component comprises:

[0032] A linkage rod, one end of which is connected to the first support block;

[0033] A movable groove is arranged on the seat body;

[0034] The damper comprises a cylinder and a retractable rod portion arranged on the cylinder, the end of the rod portion is fixed, the cylinder is movably arranged in the movable groove, and the other end of the linkage rod is connected to the cylinder;

[0035] A spring is arranged in the movable groove, one end of which is connected to the cylinder body and the other end is installed in the movable groove;

[0036] A buffer adjustment member, one end of which is connected to the cylinder body and is used to buffer the sliding of the cylinder body;

[0037] Wherein, the stabilizing components are arranged on both sides of the first supporting block.

[0038] The linkage rod is a component connecting the first support block and the damper, and one end of the linkage rod is fixedly connected to the first support block. When the first support block moves under the action of the driving structure, the linkage rod will synchronously drive the damper to move. The movable groove is arranged on the seat body, providing a space for the cylinder of the damper to move. The damper is composed of a cylinder and a retractable rod. The end of the rod is fixed, and the cylinder is movably arranged in the movable groove. When the linkage rod drives the cylinder to move, the cylinder generates a damping force through movement, thereby slowing down the moving speed of the cylinder and achieving a buffering effect, thereby reducing the impact and vibration of the clamping mechanism during movement and improving the overall stability. The spring is arranged in the movable groove, one end of which is connected to the cylinder, and the other end is installed in a fixed position of the movable groove, which can provide certain support and buffering effects for the cylinder, further enhancing the buffering effect of the stabilizing component.

[0039] As an additional component of the stabilizing assembly, the buffering adjustment piece is connected to the cylinder at one end, which can realize the precise control of the buffering effect during the sliding process of the cylinder, so that the stabilizing assembly can adapt to cylinders of different sizes and weights, ensuring that the cylinder will not be damaged during the clamping process and maintaining sufficient clamping force. In order to ensure the stability and balance of the clamping mechanism, the stabilizing assembly is set on both sides of the first support block, which not only improves the overall strength of the clamping mechanism, but also makes the cylinder more evenly stressed during the clamping process, avoiding tilting or deformation caused by excessive force on one side.

[0040] Furthermore, the buffer adjustment member includes:

[0041] A sliding guide groove, comprising a straight section and a bending section;

[0042] The matching piece includes a connecting section and an adjusting section which are hinged to each other, the connecting section and the adjusting section are matched with the sliding guide groove and can slide along the straight section and the bending section, and the connecting section is connected to the cylinder;

[0043] The connecting section and the adjusting section can slide along the straight section and the bending section, and the adjusting section can change its angle when moving from the straight section to the bending section, thereby limiting the continued movement of the connecting section.

[0044] The sliding guide groove is composed of a straight section and a bending section, which provides a path for the sliding of the matching part. The straight section allows the matching part to move in a straight line, while the bending section can guide the matching part to change the direction of movement and produce a buffering effect. The matching part is composed of a connecting section and an adjusting section that are hinged to each other. The connecting section is connected to the cylinder, and the adjusting section is connected to the connecting section through a hinge structure, so that the matching part can slide and change its angle in the sliding guide groove. When the first support block moves under the action of the driving structure, the linkage rod will drive the cylinder and the matching part to slide along the straight section of the sliding guide groove. When the matching part slides to the bending section, the adjusting section will change its angle, thereby limiting the continued movement of the connecting section. This angle change can effectively disperse the pressure in the straight direction to the bending direction, thereby achieving a buffering effect. When the adjusting section moves from the straight section to the bending section, its movement direction will change, thereby generating a certain resistance, which can slow down the movement speed of the cylinder and absorb part of the energy, and cooperate with the spring and the damper effect of the cylinder itself to achieve a soft clamping and buffering effect on the cylinder.

[0045] The design of the buffer adjustment piece enables the stabilizing assembly to adapt to cylinders of different sizes and weights. By adjusting the position of the matching piece in the sliding guide groove, the buffering effect can be controlled. This flexibility and adaptability enables the clamping mechanism to maintain sufficient stability and reliability when clamping cylinders of different sizes.

[0046] Furthermore, the present application also provides a control method for an automatic recovery device for residual liquid in a steel cylinder, comprising the following steps:

[0047] S1. Fix the fixing sleeve to the mouth of the steel cylinder, clamp the steel cylinder by the clamping mechanism and invert the steel cylinder;

[0048] S2. A portion of the residual liquid is collected into a corresponding collection device through a recovery pipe by the self-pressure of the residual liquid. After a period of time, the cylinder is inflated by a pressurized liquid discharge mechanism to increase the gas pressure in the cylinder, thereby assisting in the discharge of the residual liquid.

[0049] S3. During the process of S2, the compressor inflates the cylinder through the connecting pipe to increase the air pressure in the cylinder and discharge the remaining residual liquid in the cylinder.

[0050] The beneficial effects of this application are:

[0051] 1. The pressurized liquid discharge mechanism can effectively increase the pressure of the residual liquid inside the cylinder, forcing the residual liquid to be discharged from the cylinder more thoroughly. Compared with the traditional method, the recovery rate and discharge efficiency of the residual liquid are greatly improved;

[0052] 2. The design of the clamping mechanism enables the inverted cylinder to be firmly fixed on the fixed frame, which not only ensures the stability during the recovery process, but also reduces the risk of operators directly contacting the residual liquid in the cylinder, and improves the safety of the operation. At the same time, the clamping mechanism can be adjusted and can adapt to cylinders of different specifications and sizes, which improves the scope of application and flexibility of the device;

[0053] 3. The buffer adjustment setting can realize the precise control of the buffer effect during the sliding of the cylinder, so that the stabilizing assembly can adapt to cylinders of different sizes and weights, ensuring that the cylinder will not be damaged during the clamping process while maintaining sufficient clamping force. The clamping mechanism set on both sides not only improves the overall strength of the clamping mechanism, but also makes the cylinder more evenly stressed during the clamping process, avoiding tilting or deformation caused by excessive force on one side.

In addition to the above-mentioned technical features, the automatic recovery device for residual liquid in a steel cylinder of the embodiment of the present application also includes the following technical features.

[0075] like Figure 2 and Figure 3 As shown, the clamping mechanism includes:

[0076] The seat body 300 is disposed on the fixing frame 100 and has a cavity 310 disposed therein;

[0079] Among them, there are two groups of clamping mechanisms, which are arranged on the fixing frame 100 at upper and lower intervals, respectively used to fix the upper and lower parts of the cylinder, and the fixing structure 500 is connected to the driving structure 400, and the driving structure 400 drives the fixing structure 500 to operate.

[0080] In the embodiment of the present application, the seat body 300 is provided on the fixing frame 100 as the basic supporting component of the clamping mechanism, and a cavity 310 is provided inside the seat body 300, which provides sufficient installation and operation space for other structures. The driving structure 400 is located in the cavity 310 of the seat body 300. As the power source of the clamping mechanism, it is mainly composed of a cylinder 410 and a connecting block 420. The cylinder 410 drives the output shaft to drive the connecting block 420 to move. The fixing structure 500 is composed of a first claw body 510 and a second claw body 520, which are relatively arranged on both sides of the seat body 300. When the first claw body 510 and the second claw body 520 are combined, they will form a complete fixing ring for clamping the cylinder to ensure that cylinders of different sizes can be firmly clamped and the stability of the cylinder is maintained during the residual liquid recovery process.

[0081] At the same time, the clamping mechanism is arranged in two groups on the fixing frame 100 and is spaced apart from top to bottom, which can ensure that both the upper and lower parts of the cylinder can be effectively clamped, thereby further improving the stability of the cylinder during the residual liquid recovery process. The fixing structure 500 is connected to the driving structure 400. When the cylinder 410 receives a control signal and starts to telescope, the connecting block 420 will drive the fixing structure 500 to move accordingly, thereby realizing the clamping and releasing operations of the cylinder.

[0082] Embodiment 3:

[0083] An embodiment of the present application provides an automatic recovery device for residual liquid in a steel cylinder. In addition to the above-mentioned technical features, the automatic recovery device for residual liquid in a steel cylinder of the embodiment of the present application also includes the following technical features.

[0084] like Figures 2 to 5 As shown, the fixing structure 500 also includes:

[0085] The sliding groove 530 is provided on the base body 300 and has a sliding rail 531 disposed therein;

The first support block 541 and the second support block 542 are located outside the sliding groove 530. One end of the first support block 541 and the second support block 542 are respectively connected to the first claw body 510 and the second claw body 520, and the other end extends to the inside of the seat body 300.

[0087] The stabilizing assembly 600 is disposed on the base 300 and located on both sides of the first supporting block 541, and can make the sliding of the first sliding block more stable;

[0089] In the embodiment of the present application, the sliding groove 530 is arranged on the seat body 300, and a slide rail 531 is arranged inside the sliding groove. The design of the slide rail 531 not only ensures that the sliding assembly 540 can move smoothly in the groove, but also provides necessary guidance and support, so that the first support block 541 and the second support block 542 can move stably and accurately along a predetermined track when the driving structure 400 acts on them. The sliding assembly 540 includes a first support block 541 and a second support block 542, which are respectively connected to the first claw body 510 and the second claw body 520. Under the guidance of the sliding groove 530, the first support block 541 and the second support block 542 can move synchronously along the slide rail 531, which not only improves the accuracy and stability of the clamping action, but also enables the clamping mechanism to adapt to cylinders of different sizes, thereby improving its versatility and adaptability.

[0090] At the same time, in order to further improve the stability of the sliding assembly 540, a stabilizing assembly 600 is provided on the seat body 300 and is located on both sides of the first support block 541, which can provide additional support and buffering for the first support block 541 during the sliding process, thereby preventing it from shaking or deflecting due to excessive force, and can also make the clamping work more urgent and stable. The linkage assembly 550 is connected between the first support block 541 and the second support block 542, and can realize their synchronous operation, ensuring that they always keep synchronization during the movement process, which not only improves the working efficiency of the clamping mechanism, but also makes the clamping force more uniform and stable, thereby avoiding the occurrence of tightening and loosening.

[0091] By introducing optimized designs such as the sliding groove 530, the sliding assembly 540, the stabilizing assembly 600 and the linkage assembly 550, the fixed structure 500 has higher stability and reliability in the automatic recovery device for residual liquid in cylinders. The synergistic effect of these components not only improves the clamping force and accuracy of the clamping mechanism, but also makes the entire device more flexible and adaptable, thereby meeting the safety requirements during the residual liquid recovery process.

The gear 553 is located between the first rack 551 and the second rack 552 and meshes with them. When the driving structure 400 drives the first support block 541 to move through the connecting block 420, the gear 553 will synchronously drive the second support block 542 to move in the opposite direction, thereby achieving synchronous operation of the two.

[0105] In the embodiment of the present application, the linkage rod 610 is a component connecting the first support block 541 and the damper 630, and one end of the linkage rod 610 is fixedly connected to the first support block 541. When the first support block 541 moves under the action of the driving structure 400, the linkage rod 610 will synchronously drive the damper 630 to move. The movable groove 620 is arranged on the seat body 300, providing a moving space for the cylinder 631 of the damper 630. The damper 630 is composed of a cylinder 631 and a retractable rod 632, the end of the rod 632 is fixed, and the cylinder 631 is movably arranged in the movable groove 620. When the linkage rod 610 drives the cylinder 631 to move, the cylinder 631 generates a damping force by moving, thereby slowing down the moving speed of the cylinder 631, achieving a buffering effect, thereby reducing the impact and vibration of the clamping mechanism during the movement process, and improving the overall stability. The spring 640 is arranged in the movable groove 620, one end of which is connected to the cylinder 631, and the other end is installed at a fixed position of the movable groove 620, which can provide certain support and buffering effect for the cylinder 631, further enhancing the buffering effect of the stabilizing component 600.

[0106] The buffer adjustment member 700 is an additional component of the stabilizing assembly 600, one end of which is connected to the cylinder 631, and can realize precise control of the buffer effect during the sliding process of the cylinder 631, so that the stabilizing assembly 600 can adapt to cylinders of different sizes and weights, ensuring that the cylinder will not be damaged during the clamping process and maintaining sufficient clamping force. In order to ensure the stability and balance of the clamping mechanism, the stabilizing assembly 600 is set on both sides of the first support block 541, which not only improves the overall strength of the clamping mechanism, but also makes the cylinder more evenly stressed during the clamping process, avoiding tilting or deformation caused by excessive force on one side.

[0107] Embodiment 6:

[0108] An embodiment of the present application provides an automatic recovery device for residual liquid in a steel cylinder. In addition to the above-mentioned technical features, the automatic recovery device for residual liquid in a steel cylinder of the embodiment of the present application also includes the following technical features.

[0109] like Figure 4 and Figure 5 As shown, the buffer adjustment parts 700 pieces include:

[0110] The sliding guide groove 710 includes a straight section 711 and a bending section 712;

[0111] The matching piece 720 includes a connecting section 721 and an adjusting section 722 which are hinged to each other. The connecting section 721 and the adjusting section 722 match the sliding guide groove 710 and can slide along the straight section 711 and the bending section 712. The connecting section 721 is connected to the cylinder 631.

[0112] The connecting section 721 and the adjusting section 722 can slide along the straight section 711 and the bending section 712 , and the adjusting section 722 can change its angle when moving from the straight section 711 to the bending section 712 , thereby limiting the continued movement of the connecting section 721 .

[0113] In the embodiment of the present application, the sliding guide groove 710 is composed of a straight section 711 and a bent section 712, which provides a path for the sliding of the matching piece 720. The straight section 711 allows the matching piece 720 to move in a straight line, while the bent section 712 can guide the matching piece 720 to change the direction of movement and produce a buffering effect. The matching piece 720 is composed of a connecting section 721 and an adjusting section 722 that are hinged to each other. The connecting section 721 is connected to the cylinder 631, and the adjusting section 722 is connected to the connecting section 721 through a hinge structure, so that the matching piece 720 can slide in the sliding guide groove 710 and change its angle. When the first support block 541 moves under the action of the driving structure 400, the linkage rod 610 will drive the cylinder 631 and the matching piece 720 to slide along the straight section 711 of the sliding guide groove 710. When the matching piece 720 slides to the bending section 712, the adjustment section 722 will change its angle, thereby limiting the continued movement of the connecting section 721. This angle change can effectively disperse the pressure in the straight direction to the bending direction, thereby achieving a buffering effect. When the adjustment section 722 moves from the straight section 711 to the bending section 712, its movement direction will change, thereby generating a certain resistance, which can slow down the movement speed of the cylinder 631 and absorb part of the energy, and cooperate with the spring 640 and the damper 630 of the cylinder 631 itself to achieve a soft clamping and buffering effect on the cylinder.

[0114] The design of the buffer adjustment member 700 enables the stabilizing assembly 600 to adapt to steel cylinders of different sizes and weights, and the buffering effect can be controlled by adjusting the position of the matching member 720 in the sliding guide groove 710. This flexibility and adaptability enables the clamping mechanism to maintain sufficient stability and reliability when clamping steel cylinders of different sizes.

[0119] S3. In the process of S2, the compressor 221 inflates the steel cylinder through the connecting pipe 222 to increase the air pressure in the steel cylinder and discharge the remaining residual liquid in the steel cylinder.
