Description

Technical Field

[0001] The present invention belongs to the technical field of acetylene cylinder filling, and particularly relates to an acetone and DMF filling system and method for acetylene cylinders. Background Art

[0002] Acetylene is a gas with wide applications in industry, such as in metal welding and cutting processes, and is also an important raw material for the preparation of various chemical products such as vinyl chloride and acetic acid. However, acetylene is prone to decomposition and instability under high pressure, and it is extremely likely to explode when stored directly in a high-pressure gaseous state. Therefore, acetylene is usually dissolved in a solvent for storage. Currently, acetone is commonly used as a solvent in China to be filled into acetylene cylinders to achieve the dissolution and storage of acetylene.

[0003] During the filling process of existing acetylene cylinders, manual filling is carried out one by one. When filling, it is necessary to first connect and fix the connecting mechanism to the acetylene cylinder, then open the valve on the acetylene cylinder, and finally start the air pump for filling. The process is very cumbersome, time-consuming and laborious, especially when filling multiple acetylene cylinders, it is very troublesome.

[0004] Therefore, research and improvement are carried out on the existing structure and deficiencies, and an acetone and DMF filling system and method for acetylene cylinders are provided, in order to achieve a more practical purpose. Summary of the Invention

[0016] A method for filling acetone and DMF into acetylene cylinders, using the acetone and DMF filling system for acetylene cylinders as described above, includes the following steps:

[0017] S1 Place the filling plate above the neatly arranged acetylene cylinders, and control the first hydraulic rod to descend so that each group of pressing plates presses and fixes the corresponding acetylene cylinder body.

[0018] S2 Control the adjusting plate to move above one of the acetylene cylinders, and control the first hydraulic rod below the adjusting plate to contract. At this time, the other several acetylene cylinders below the filling plate can effectively support the filling plate through the pressing plates and the first hydraulic rod. Therefore, the filling plate can drive the acetylene cylinder to rise under the contraction of the first hydraulic rod, and then control the acetylene cylinder to rotate to a suitable angle so that the acetylene cylinder outlet is aligned with the communication hole. Then control the second hydraulic rod to extend to control the communication hole to communicate and seal with the acetylene cylinder outlet.

[0019] S3 Then control the adjusting lever to connect with the switch of the acetylene cylinder, open the acetylene cylinder switch through the adjusting lever, and then start the air pump to input the material in the filling barrel into the acetylene cylinder.

[0020] S4 After the filling is completed, control the adjusting plate to move above the corresponding acetylene cylinder in sequence, and then repeat the above operations to automatically fill the acetylene cylinder.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] The design of multiple groups of first hydraulic rods can control multiple pressing plates to press and fix the bodies of multiple acetylene cylinders. After the acetylene cylinders are fixed, the positions of the acetylene cylinders cannot be changed at this time and can only move vertically up and down, so that the adjusting lever can better engage and connect with the valve switch of the acetylene cylinder. In this way, when it is necessary to control one of the acetylene cylinders to rise, the other several acetylene cylinders and the filling plate can form a whole, which can effectively support the filling plate, and thus the rising of one of the acetylene cylinders can be realized. The design of the driving wheels that can be adjusted back and forth and rotated can control the rotation of the acetylene cylinder body through the rotation of the driving wheels, and can effectively control the acetylene cylinder to rotate to a suitable angle, so that the acetylene cylinder outlet can accurately dock and seal with the communication hole. The design of the adjustable movement of the adjusting plate can realize the filling of different acetylene cylinders in sequence through the adjustment of the position of the adjusting plate. The adjustable back-and-forth movement of the filling frame can effectively press and seal between the acetylene cylinder outlet and the communication hole under the action of the second hydraulic rod, ensuring the overall sealing performance;

[0023] The design of the trolley board and the rollers can adjust the position of the trolley board in a timely manner through the rotation of the rollers, so as to achieve filling of acetylene cylinders at different positions.

[0024] With such a design, through the automatic positioning and rotation control of the acetylene cylinders, the automatic filling of multiple acetylene cylinders is realized.

The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0042] Example 1, please refer to Figure 1 、 Figure 2 and Figure 3 、 Figure 6 , an acetylene cylinder 1 acetone and DMF filling system, including a filling plate 4, a filling barrel 22 and a trolley plate 2. A plurality of groups of uniformly distributed first hydraulic rods 45 are provided at the bottom of the filling plate 4. Each group of the first hydraulic rods 45 is respectively located directly above the corresponding acetylene cylinder 1 arranged in a neat row. An extrusion plate 44 for squeezing and fixing the body of the acetylene cylinder 1 is provided at the bottom of the first hydraulic rod 45. A plurality of rotatable and position-adjustable rotating wheels 445 are provided on the inner side wall of the extrusion plate 44. An adjusting plate 47 is provided at the bottom of the filling plate 4. The adjusting plate 47 passes through each group of first hydraulic rods 45 along a set track and can move back and forth. A filling frame 472 that can move back and forth is provided at the bottom of the adjusting plate 47. A second hydraulic rod 473 for extrusion is provided on one side of the filling frame 472. An adjusting clamping rod 471 that can move up and down and rotate is provided on the adjusting plate 47. The adjusting clamping rod 471 is used to control the switch of the acetylene cylinder 1. A communication hole for communicating with the outlet of the acetylene cylinder 1 is provided on the other side of the filling frame 472. A filling pipe 43 is provided on the other side of the communication hole and is connected. The filling barrel 22 is placed on the trolley plate 2. Rolling wheels 21 for controlling the movement are provided at the bottom of the trolley plate 2. An air pump 3 is provided in the filling barrel 22. The outlet of the air pump 3 is communicated with the filling pipe 43.

[0043] The design of multiple groups of first hydraulic rods 45 can control multiple pressing plates 44 to press and fix the bodies of multiple acetylene cylinders 1. After the acetylene cylinders 1 are fixed, their positions cannot be changed at this time, and they can only move vertically up and down. Thus, the adjusting clamping rod 471 can better engage and connect with the valve switch of the acetylene cylinder 1. In this way, when it is necessary to control one of the acetylene cylinders 1 to rise, the other several acetylene cylinders 1 and the filling plate 4 can form an integral body, which can effectively support the filling plate 4, and thus realize the rising of one of the acetylene cylinders 1. The design of the driving wheel that can be adjusted back and forth and rotated can realize the rotation control of the body of the acetylene cylinder 1 through the rotation of the driving wheel, and can effectively control the acetylene cylinder 1 to rotate to a suitable angle, so that the outlet of the acetylene cylinder 1 can accurately dock and seal with the communication hole. The movable design of the adjusting plate 47 can realize the filling of different acetylene cylinders 1 in sequence through the adjustment of the position of the adjusting plate 47. The reciprocating movement of the filling frame 472 can effectively press and seal between the outlet of the acetylene cylinder 1 and the communication hole under the action of the second hydraulic rod 473, ensuring the overall sealing performance;

[0044] The design of the trolley plate 2 and the rollers 21 can timely adjust the position of the trolley plate 2 through the rotation of the rollers 21 to realize the filling of acetylene cylinders 1 at different positions;

[0045] Such a design realizes the automatic filling of multiple acetylene cylinders 1 through the automatic positioning and rotation control of the acetylene cylinders 1.

[0046] In this embodiment, please refer to Figure 3 、 Figure 4 and Figure 5 . The first hydraulic rods 45 are 4 groups, and each group of the first hydraulic rods 45 has four. The filling plate 4 is provided with a hollow driving groove 46. One side of the driving groove 46 is provided with a fixedly connected first sliding rod 465. A first sliding sleeve 467 is slidably connected to the first sliding rod 465. One side of the first sliding sleeve 467 is provided with a second sliding rod 466 that is connected and perpendicular to the first sliding rod 465. A second sliding sleeve 468 is slidably connected to the second sliding rod 466. The second sliding sleeve 468 is fixedly connected to the adjusting plate 47, and the other end of the second sliding sleeve 468 is rotatably connected to a transfer plate 469. The middle of the driving groove 46 is provided with a rotatable rotating plate 463. One end of the transfer plate 469 is provided with a fixedly connected third sliding rod 462. The other end of the third sliding rod 462 slidably passes through the middle of the rotating plate 463. A return spring 461 is sleeved on the third sliding rod 462 between the rotating plate 463 and the transfer plate 469. The bottom of the driving groove 46 below the first sliding rod 465 and the second sliding rod 466 is provided with a U-shaped first track groove 48. The filling frame 472 is arranged in the first track groove 48.

[0047] The design of the first sliding rod 465, the second sliding rod 466, the third sliding rod 462 and the return spring 461 enables the adjusting plate 47 to move along a square trajectory through the rotation of the rotating plate 463, so that the adjusting plate 47 can move to a set position as needed. The design of having four first hydraulic rods 45 not only ensures that the adjusting plate 47 can shuttle better during movement, but also, due to the cylindrical characteristics of the acetylene cylinders 1, there will be a certain gap between the acetylene cylinders 1. The design of having four first hydraulic rods 45 enables the pressing plate 44 to make full use of the gap, so that the pressing plate 44 can better fix the acetylene cylinders 1.

[0048] In this embodiment, please refer to Figure 1 、 Figure 2 , a U-shaped second track groove 41 is provided at the other end of the driving groove 46, and the filling pipe 43 is arranged in the second track groove 41. By arranging the filling pipe 43 in the second track groove 41, the movement of the filling pipe 43 will not be restricted by the first hydraulic rod 45, ensuring the overall stability.

[0049] In this embodiment, please refer to Figure 1 、 Figure 2 , a driving motor 42 is provided above the filling plate 4, and the output end of the driving motor 42 is connected to the rotating plate 463. Among them, the driving motor 42 is a motor that can rotate forward and backward.

[0050] In this embodiment, please refer to Figure 2 、 Figure 6 , the pressing plate 44 includes a first pressing plate 441 and a second pressing plate. The first pressing plate 441 and the second pressing plate are fixedly connected. The first pressing plate 441 is used for squeezing the inclined surface of the bottle mouth, and the second pressing plate is used for squeezing the cylindrical body of the bottle. An extrusion groove is provided on the side wall of the second pressing plate, and symmetrically distributed third hydraulic rods 444 are arranged in the extrusion groove. A rotating shaft is rotatably connected between the ends of the third hydraulic rods 444, and a rotating wheel 445 is fixedly connected to the rotating shaft. A rotating motor 442 is provided on one of the pressing plates 44, and the output end of the rotating motor 442 is connected to the rotating shaft. The bottom of the second pressing plate is inclined for guiding the flow. Among them, the rotating motor 442 is connected to the rotating shaft through a chain 443.

[0051] The design of the first pressing plate 441 and the second pressing plate enables the pressing plate 44 to better limit the position of the bottle body. The design of the inclined bottom of the second pressing plate for guiding the flow can, when the acetylene cylinders 1 are not placed neatly, through the inclined design, fully guide the flow, so that the pressing plate 44 can better limit the position of the bottle body. The third hydraulic rods 444 are used to control the back-and-forth movement of the rotating wheel 445, so that the rotating wheel 445 can effectively squeeze and fix the bottle body.

[0052] In this embodiment, please refer to Figure 7 , the acetylene cylinder 1 includes a cylinder body, a bottle valve 13, a valve rod 12 and a liquid inlet pipe 11. The valve rod 12 is used to control the opening and closing of the bottle valve 13. The liquid inlet pipe 11 is communicated with the inlet of the bottle valve 13, and the liquid inlet pipe 11 protrudes outside the bottle valve 13. The adjusting clamping rod 471 is clamped and connected with the valve rod 12. The second hydraulic rod 473 is used to squeeze the liquid inlet pipe 11 and the communication hole for connection and sealing. The reciprocating movement and rotation of the adjusting clamping rod 471 can be controlled by a hydraulic rod for its telescopic movement and a motor for its rotation. This is the prior art. Therefore, in this application, no more description will be given here. A hydraulic rod can be arranged on the adjusting plate 4, and then a motor can be arranged at the end of the hydraulic rod, and the output end of the motor is connected with the adjusting clamping rod 471, so as to realize the reciprocating movement and rotation of the adjusting clamping rod 471.

[0053] In this embodiment, a fixed-connected induction plate is arranged in the filling frame 472 on one side of the communication hole. A plurality of pressure sensors are arranged on the induction plate. The pressure sensors realize the alignment of the liquid inlet pipe 11 and the communication hole by colliding with the liquid inlet pipe 11. The design of the induction plate and the pressure sensors can judge the position of the liquid inlet pipe 11 through the contact induction of the pressure sensors, so that the liquid inlet pipe 11 can move to the corresponding position effectively and accurately, realizing automatic alignment.

[0054] In this embodiment, please refer to Figure 1 , a storage battery and a controller are arranged on the trolley plate 2. The controller is electrically connected to the first hydraulic rod 45, the second hydraulic rod 473, the third hydraulic rod 444, the fourth hydraulic rod 405, the pressure sensor, the driving motor 42 and the rotating motor 442 respectively.

[0055] Embodiment 2, the same parts as those in Embodiment 1 will not be described. The differences from Embodiment 1 are as follows: In this embodiment, please refer to Figure 7 , Figure 8, the filling plate 4 includes a first plate 401, a second plate 402, a third plate 403 and a fourth plate 404. A fourth hydraulic rod 405 is connected between the first plate 401, the second plate 402, the third plate 403 and the fourth plate 404. It further includes a fifth plate 406 and a sixth plate 407. A fourth hydraulic rod 405 is connected between the fifth plate 406 and the sixth plate 407. A fourth hydraulic rod 405 is connected between the fifth plate 406 and the second plate 402. A fourth hydraulic rod 405 is connected between the sixth plate 407 and the first plate 401. The fifth plate 406 and the sixth plate 407 are used to place the first hydraulic rods 45 at the upper corners of the third plate 403 and the fourth plate 404. Among them, the first sliding rod 465 is a telescopic rod with adjustable length. The telescopic rod includes a first rod and a second rod. A recovery groove is provided at one end of the first rod. An extension rod is slidably connected in the recovery groove. The extension rod is fixedly connected to the second rod. A fixing plate 464 for fixing both ends of the first sliding rod 465 is provided in the driving groove 46. Protruding plates are fixedly connected to the ends of the second sliding rod 466 and the third sliding rod 462 to prevent slipping.

[0056] The design of the telescopic rod enables the first sliding rod 465 to adaptively extend during the movement of the third plate 403 and the fourth plate 404, and automatically return to the initial position after the position adjustment is completed, thus ensuring the stability of the trajectory movement of the adjusting plate 47 and not affecting the original movement trajectory of the adjusting plate 47.

[0057] Due to the existence of the first track groove 48, the first hydraulic rods 45 on the third plate 403 and the fourth plate 404 cannot be fully installed on the third plate 403 and the fourth plate 404. The design of the fifth plate 406 and the sixth plate 407 can install the first hydraulic rods 45 that cannot be installed on the third plate 403 and the fourth plate 404, and can move synchronously with the third plate 403 and the fourth plate 404, ensuring the overall stability.

[0058] The original integrated filling plate 4 is split into a first plate 401, a second plate 402, a third plate 403, and a fourth plate 404, and the movement is controlled by a fourth hydraulic rod 405. With such a design, after the acetylene cylinder 1 below the filling plate 4 is filled, first release the limit fixation of the pressing plate 44 on the acetylene cylinder 1 on the side that needs to move. Then, control the corresponding first hydraulic rod 45 to rise. Since the other two acetylene cylinders 1 and the filling plate 4 are an integral whole, control the fourth hydraulic rod 405 to make the two sets of first hydraulic rods 45 that are released from fixation move above the adjacent waiting acetylene cylinder 1. Then, control the pressing plate 44 to fix the waiting acetylene cylinder 1. Next, in the same way, for the two sets of first hydraulic rods 45 above the other two acetylene cylinders 1, by contracting the fourth hydraulic rod 405, the two sets of first hydraulic rods 45 can be automatically displaced until above the next acetylene cylinder 1. Through such an alternating movement method, the filling plate 4 can automatically move along the direction in which the acetylene cylinders 1 are arranged, can automatically move above the corresponding acetylene cylinder 1, and perform automatic filling. At the same time, the rollers 21 at the bottom of the trolley plate 2 can also be set to be electrically controlled, so that when the filling plate 4 is moving, control the trolley plate 2 to move automatically in synchronization, ensuring the stability of filling.

[0059] In this embodiment, a tension sensor is also provided at the connection between the first hydraulic rod 45 and the pressing plate 44. The design of the tension sensor enables the acetylene cylinder 1 to sense the filling amount in real time during the filling process, can automatically weigh the acetylene cylinder 1, and thus can better control the amount of filling.

[0060] During the repeated use of acetylene cylinders, the consumption of acetone is inevitable. Too little acetone will directly reduce the amount of dissolved acetylene, making the steel cylinder unable to be fully utilized; but the amount of acetone cannot be too large either, otherwise either there will be too much dissolved acetylene and the air pressure will increase, which also does not meet the requirements. Therefore, before each filling of acetylene, it is necessary to ensure that the amount of acetone inside the cylinder body is appropriate. Therefore, the design of the tension sensor can more accurately control the addition amount.

[0061] A method for filling acetone and DMF for acetylene cylinders, using the acetone and DMF filling system for acetylene cylinders 1 as described above, includes the following steps:

[0062] S1 Place the filling plate 4 above the neatly arranged acetylene cylinders 1, control the first hydraulic rod 45 to descend, and make each pressing plate 44 press and fix the corresponding acetylene cylinder 1 body;

[0063] Control the adjustment plate 47 to move above one of the acetylene cylinders 1, and control the first hydraulic rod 45 below the adjustment plate 47 to contract. At this time, several other acetylene cylinders 1 below the filling plate 4 can effectively support the filling plate 4 through the pressing plate 44 and the first hydraulic rod 45. Therefore, the filling plate 4 can drive the acetylene cylinder 1 to rise under the contraction of the first hydraulic rod 45, and then control the acetylene cylinder 1 to rotate to an appropriate angle so that the outlet of the acetylene cylinder 1 is aligned with the communication hole. Then, control the second hydraulic rod 473 to extend to control the communication hole to be connected and sealed with the outlet of the acetylene cylinder 1;

[0064] S3 Then control the adjustment lever 471 to be connected to the switch of the acetylene cylinder 1, open the switch of the acetylene cylinder 1 through the adjustment lever 471, and then start the air pump 3 to input the material in the filling barrel 22 into the acetylene cylinder 1;
