Description

Technical Field

[0001] The utility model relates to the field of gas purification, in particular to a purification device for special gases. Background Art

[0002] Special gases refer to pure gases, high-purity gases, or binary or multi-component mixed gases with special gas requirements produced by high-purity elemental gases used in specific areas. In the fields of high-purity aluminum production and semiconductor technology, high-purity argon gas is used. However, ordinary argon gas cannot meet the use requirements required by the industry due to its low purity. Therefore, it is necessary to use a purification device to purify the argon gas to make it high-purity argon gas before it is used in the fields of high-purity aluminum production and semiconductor technology.

[0003] When purifying argon, an argon purifier is generally required. This type of machine mainly uses deoxidizers and purification materials such as molecular sieves to purify the argon, so that the purity of the argon can meet the required purity standards.

[0004] When an existing purification device is in use, it is generally equipped with various related electrical components inside, and most of these electrical components are fixedly installed inside the purification device. Therefore, when the staff repairs or replaces the electrical components inside the purification device, they need to reach into the control room. However, due to the limited space inside the control room of the purification device, when the staff put their hands into the control room of the purification device, it is easy to cause related operations to be inconvenient.

[0005] Therefore, it is necessary to provide a new special gas purification device to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a purification device for special gases.

[0007] The utility model provides a purification device for special gases, comprising a body, wherein a control chamber is arranged in the body, and a sealing door A is rotatably connected to the control chamber, inner walls on both sides of the control chamber are fixedly connected to slide rails, and a mounting frame is slidably connected to the slide rails, a plurality of fixedly connected limit springs are arranged between the mounting frame and the inner wall of the control chamber, and two fixedly connected traction ropes are arranged between the mounting frame and the sealing door A.

[0008] Preferably, both sides of the body are fixedly connected with fixing frames, and a rack is slidably connected inside the fixing frame, and the top of the rack is fixedly connected with a mounting plate, and the mounting plate is respectively provided with mutually communicating limiting circular holes and limiting hole strips.

[0009] Preferably, a gear meshing with the rack is rotatably connected inside the fixing frame, and a knob is rotatably connected to one side of the fixing frame, and the knob is fixedly connected to the gear.

[0010] Preferably, a sleeve rod is provided in the limiting hole strip, one end of the sleeve rod is provided with two fixedly connected fixing balls, and the other end of the sleeve rod is sleeved with and threadedly connected with a screw rod.

[0011] Preferably, the limiting circular hole is located below the limiting hole bar, and the width of the limiting hole bar is smaller than the diameter of the limiting circular hole.

[0012] Preferably, both sides of the control room are rotatably connected with pulleys through a frame, and the traction ropes are respectively located on the pulleys on the same side and are in contact with the pulleys.

[0013] Preferably, a sealing door B is rotatably connected to the body, heat dissipation holes are provided on both sides of the body, and universal wheels are rotatably connected to the four corners of the bottom of the body.

[0014] Compared with the related art, the special gas purification device provided by the utility model has the following beneficial effects:

[0015] 1. The utility model installs all control components on the mounting frame. When it is necessary to inspect and repair the electrical components in the control room, the sealed door A is opened. During the opening process of the sealed door A, the mounting frame is pulled toward the door of the control room by the traction rope. When the sealed door A is fully opened, the mounting frame drives the electrical components to move to the door of the control room. At this time, the staff can directly inspect and repair the electrical components on the mounting frame, avoiding the problem that the traditional device needs to put the hand into the control room when inspecting the electrical components, which is easy to cause inconvenience for the staff due to the small space in the control room. The auxiliary function of the device for the staff is effectively improved.

[0016] 2. The utility model fixes the screw rod on the wall, and then uses the knob to drive the gear to rotate, thereby driving the rack to move upward. During the upward movement of the rack, the mounting plate is driven to move together, and then the limiting circular hole is put on the sleeve rod, and then the knob is rotated in the opposite direction, and the gear is used to drive the rack to move downward, so that the limiting hole bar is stuck on the sleeve rod. At this time, the fixation of the machine body can be completed, avoiding the problem that the traditional machine body is easily displaced due to external force during use, thereby causing the wires connecting the machine body and other devices to fall off easily after the machine body moves.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 6 A purification device for special gases provided by an embodiment of the utility model includes a control chamber 11 provided in a body 1, and a sealing door A12 is rotatably connected to the control chamber 11, a sealing door B13 is rotatably connected to the body 1, heat dissipation holes 14 are provided on both sides of the body 1, and universal wheels 15 are rotatably connected to the four corners of the bottom of the body 1.

[0027] It should be noted that the machine body 1 is the main body of the purification device for argon special gas, that is, the argon purifier. The control room 11 is used to install various related electrical components. During the operation of the machine body 1, it can be connected to other equipment for storing argon. Then, the machine body 1 is started, and the deoxidizer and molecular sieve and other purification materials in the machine body 1 are used to complete the purification of argon. During the operation of the machine body 1, the heat generated inside it will be discharged through the heat dissipation holes 14, and the universal wheels 15 can be used to move the machine body 1.

[0028] In the embodiments of the present invention, please refer to Figure 2 and Figure 6 The inner walls on both sides of the control room 11 are fixedly connected with slide rails 2, and the slide rails 2 are slidably connected with mounting frames 21. A plurality of fixedly connected limit springs 22 are provided between the mounting frames 21 and the inner walls of the control room 11, and two fixedly connected traction ropes 23 are provided between the mounting frames 21 and the sealing door A12;

[0029] Both sides of the control room 11 are rotatably connected to pulleys 3 through a frame, and the traction ropes 23 are respectively located on the pulleys 3 on the same side and are in contact with the pulleys 3 .

[0030] It should be noted that: when the sealed door A12 is opened, the sealing door A12 can use the traction rope 23 to drive the mounting frame 21 to move toward the door of the control room 11 during the rotation process. During this process, the mounting frame 21 will drive the limit spring 22 to stretch. When the sealed door A12 is fully opened, the mounting frame 21 will move to the door of the control room 11 along the slide rail 2. At this time, the staff can repair or replace the electrical components on the mounting frame 21 without putting their hands into the control room 11. When the repair work is completed, the sealed door A12 is closed. During the process of closing the sealed door A12, the pulling force of the traction rope 23 on the mounting frame 21 disappears, and the limit spring 22 contracts and drives the mounting frame 21 back to its original position.

[0031] It is also necessary to explain that the pulley 3 can limit and support the traction rope 23. When the sealed door A12 is opened, the pulley 3 can limit the traction rope 23, so that the distance between the sealed door A12 and the mounting frame 21 can be lengthened, ensuring that the mounting frame 21 can be moved to the door of the control room 11 after the sealed door A12 is opened.

[0032] It is worth noting that: a telescopic rod is provided inside the limit spring 22. By using the limit spring 22 and the telescopic rod together, a certain space can be reserved between the mounting frame 21 and the inner wall of the control room 11. The space can be used to place various connecting wires of the electrical components on the mounting frame 21. When installing the electrical components, it is necessary to leave a certain length of the wires on the electrical components so that when the sealed door A12 is opened, the mounting frame 21 can normally drive the electrical components thereon to move.

[0033] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5, both sides of the machine body 1 are fixedly connected with a fixing frame 4, and a rack 41 is slidably connected in the fixing frame 4, a mounting plate 42 is fixedly connected to the top of the rack 41, and the mounting plate 42 is respectively provided with a limiting circular hole 43 and a limiting hole strip 44 that are interconnected with each other, a gear 45 that meshes with the rack 41 is rotatably connected in the fixing frame 4, a knob 46 is rotatably connected to one side of the fixing frame 4, and the knob 46 is fixedly connected to the gear 45, the limiting circular hole 43 is located below the limiting hole strip 44, and the width of the limiting hole strip 44 is smaller than the diameter of the limiting circular hole 43;

[0034] A sleeve rod 5 is disposed inside the position-limiting hole strip 44 . One end of the sleeve rod 5 is provided with two fixedly connected fixing balls 51 . The other end of the sleeve rod 5 is sleeved with and threadedly connected with a screw rod 52 .

[0035] It should be noted that the gear 45 is driven to rotate by the knob 46, so that the gear 45 drives the rack 41 to rise, and the rack 41 can synchronously drive the mounting plate 42 to move during the movement. When the knob 46 is rotated in the reverse direction, the gear 45 can be driven to rotate in the reverse direction, and the gear 45 drives the rack 41 to descend, and at this time, the rack 41 can synchronously drive the mounting plate 42 to descend.

[0036] It should also be noted that: the screw 52 is fixed to the wall with a screw, and then the sleeve rod 5 is extended by rotating the sleeve rod 5 according to the required distance between the body 1 and the wall, thereby changing the length of the sleeve rod 5 and the screw 52, ​​so as to control the distance between the body 1 and the wall after being fixed. After the screw 52 is fixed, the knob 46 is rotated, and the gear 45 is used to drive the rack 41 to rise. When the limiting circular hole 43 is aligned with the fixing ball 51, the body 1 is moved, the limiting circular hole 43 passes through the fixing ball 51, and is sleeved on the sleeve rod 5, and it is ensured that the mounting plate 42 is located between the two fixing balls 51. At this time, the knob 46 is rotated in the opposite direction, and the rack 41 is driven to descend by the reverse gear 45. At this time, the mounting plate 42 descends together with the rack 41, and the limiting hole strip 44 is clamped on the sleeve rod 5. At this time, the sleeve rod 5, the fixing ball 51 and the mounting plate 42 cooperate to complete the fixing work of the body 1.

[0037] The working principle of the special gas purification device provided by the utility model is as follows:

[0038] First, use a screw to fix the screw rod 52 on the wall. Then, according to the required distance between the body 1 and the wall, the sleeve rod 5 is rotated to extend it, and the length of the sleeve rod 5 and the screw rod 52 is changed. Then, the body 1 is moved to this position, and the knob 46 is turned to drive the rack 41 to rise by the gear 45. When the limiting circular hole 43 is aligned with the fixing ball 51, the body 1 is moved, and the limiting circular hole 43 passes through the fixing ball 51 and is sleeved on the sleeve rod 5, and it is ensured that the mounting plate 42 is located between the two fixing balls 51. At this time, the knob 46 is rotated in the opposite direction, and the rack 41 is driven to descend by the reverse gear 45. At this time, the mounting plate 42 is lowered together with the rack 41, and the limiting hole strip 44 is clamped on the sleeve rod 5. At this time, the sleeve rod 5, the fixing ball 51 and the mounting plate 42 cooperate to complete the fixing work of the body 1.

[0039] Then, the machine body 1 is connected to other devices for storing argon gas, and then the machine body 1 is started, and the deoxidizer and purification materials such as molecular sieve in the machine body 1 are used to purify the argon gas;

[0040] When the sealing door A12 is opened, the sealing door A12 can use the traction rope 23 to drive the mounting frame 21 to move toward the door of the control room 11 during the rotation process. During this process, the mounting frame 21 will drive the limit spring 22 to stretch. When the sealing door A12 is fully opened, the mounting frame 21 will move to the door of the control room 11 along the slide rail 2. At this time, the staff can repair or replace the electrical components on the mounting frame 21 without putting their hands into the control room 11. When the maintenance work is completed, when the sealing door A12 is closed, during the process of closing the sealing door A12, the pulling force of the traction rope 23 on the mounting frame 21 disappears. At this time, the limit spring 22 contracts and drives the mounting frame 21 back to its original position, and the machine body 1 can continue to be used normally for argon purification.

[0041] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
