Description

Technical Field

[0001] This utility model relates to the field of fluid control technology, and in particular to a gas switching device. Background Technology

[0002] A gas switching device is a piece of equipment used to switch, distribute, and control different gases. In chemical production, it is often necessary to switch different gases at different reaction stages. For example, in the synthesis of ammonia, it is necessary to switch between gases such as hydrogen and nitrogen in different processes. In steel smelting, gas switching devices are also used to switch between oxygen, nitrogen, argon, etc., for different smelting stages.

[0003] In existing technologies, common gas switching devices lack efficient power and transmission structures, making it impossible to quickly switch between different gas channels. The switching process requires manual operation of multiple valves or pipeline connection components, which is cumbersome and time-consuming, failing to meet the rapid gas switching requirements of various processes and reducing production efficiency. To improve upon this, a gas switching device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gas switching device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas switching device includes a fixed sleeve, a rotating frame and a rotating cylinder rotatably mounted on the fixed sleeve, a fixed motor mounted on the fixed sleeve, the fixed motor connected to the rotating cylinder via a rotating mechanism, an outlet pipe on the rotating cylinder, multiple functional boxes mounted on the rotating frame, each functional box containing a movable chamber and a rotating chamber, a piston plate within the movable chamber, and a reciprocating screw rotatably extending outside the functional box within the rotating chamber, the piston plate connected to the reciprocating screw via a connecting mechanism, an inlet pipe connecting the movable chamber and the fixed sleeve, a connection port on the rotating cylinder, and a movable motor mounted on the rotating cylinder via a synchronous plate, the movable motor connected to the reciprocating screw via a locking mechanism.

[0007] Preferably, the rotating mechanism includes a gear mounted on the output shaft of a fixed motor, and the rotating cylinder is provided with a gear ring that meshes with the gear.

[0008] Preferably, the connecting mechanism includes a connecting frame threaded onto a reciprocating screw, the end of which is fixedly connected to a piston plate.

[0009] Preferably, the engaging mechanism includes an arc-shaped block mounted on the output shaft of the movable motor, and a rotating block is provided at the end of the reciprocating screw, with an arc-shaped opening corresponding to the arc-shaped block on the rotating block.

[0010] Preferably, the functional box is also provided with an air supply pipe, and both the air supply pipe and the air inlet pipe are provided with a one-way valve.

[0011] Preferably, the piston plate is slidably installed in the movable chamber, and the fixed sleeve and the rotating cylinder are also slidably connected in a sealed manner.

[0012] The beneficial effects of this utility model are:

[0013] 1. By driving a fixed motor to mesh with a gear and a gear ring, the rotating cylinder is rotated. This allows for quick switching between different functional boxes and the rotating cylinder, thus facilitating the switching of different gases and meeting the gas requirements of various processes.

[0014] 2. The locking mechanism utilizes the cooperation between the arc-shaped block and the arc-shaped opening on the rotating block. When the arc-shaped block enters the arc-shaped opening, the movable motor can drive the reciprocating screw to rotate. The operation is simple and the connection is stable, ensuring the reliability of the gas switching process. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3A gas switching device includes a fixed sleeve 2, a rotating frame 1 and a rotating cylinder 3 rotatably mounted on the fixed sleeve 2, a fixed motor 8 mounted on the fixed sleeve 2, the fixed motor 8 being connected to the rotating cylinder 3 via a rotating mechanism, an outlet pipe 4 mounted on the rotating cylinder 3, multiple function boxes 5 mounted on the rotating frame 1, each function box 5 containing a movable chamber 16 and a rotating chamber 17, a piston plate 18 within the movable chamber 16, and a reciprocating screw 19 extending to the outside of the function box 5 rotatably mounted within the rotating chamber 17, the piston plate 18 being connected to the reciprocating screw 19 via a connecting mechanism, the movable chamber 16 being connected to the fixed sleeve 2 via an inlet pipe 14, a connecting port 21 mounted on the rotating cylinder 3, a movable motor 12 mounted on the rotating cylinder 3 via a synchronous plate 11, and the movable motor 12 being connected to the reciprocating screw 19 via a locking mechanism.

[0021] The rotating mechanism includes a gear 9 mounted on the output shaft of the fixed motor 8, and a gear ring 10 on the rotating cylinder 3 that meshes with the gear 9. When the fixed motor 8 is started, it can drive the gear 9 to rotate, and the gear 9 can drive the rotating cylinder 3 to rotate relative to the fixed sleeve 2 with the help of the gear ring 10, which can drive the connection port 21 to connect to the end of one of the air intake pipes 14.

[0022] The connecting mechanism includes a connecting frame 20 threadedly mounted on the reciprocating screw 19, with the end of the connecting frame 20 fixedly connected to the piston plate 18. The connecting frame 20 has a U-shaped design, with its horizontal portion sliding through the inner wall of the rotating chamber 17 and extending into the movable chamber 16. Therefore, it has its own limit and will not rotate with the reciprocating screw 19.

[0023] The reciprocating screw 19 has threads only on the outer wall of the part inside the rotating chamber 17.

[0024] The engaging mechanism includes an arc-shaped block 15 mounted on the output shaft of the movable motor 12, and a rotating block 7 at the end of the reciprocating screw 19. The rotating block 7 has an arc-shaped opening 13 corresponding to the arc-shaped block 15. When the arc-shaped block 15 rotates into the arc-shaped opening 13 on one of the rotating blocks 7, the movable motor 12 starts, and the arc-shaped block 15 can then cooperate with the rotating block 7 to drive the reciprocating screw 19 to rotate together.

[0025] The function box 5 is also equipped with a gas supply pipe 6, and both the gas supply pipe 6 and the air inlet pipe 14 are equipped with one-way valves. The one-way valves control the gas flow direction, and the gas can only enter the active chamber 16 through the gas supply pipe 6. The gas in the active chamber 16 can only enter the rotating cylinder 3 through the air inlet pipe 14 and the connection port 21, and finally enter the target device through the air outlet pipe 4.

[0026] The piston plate 18 is slidably and sealed within the movable chamber 16, and the fixed sleeve 2 and the rotating cylinder 3 are also slidably and sealed. The aforementioned slidable sealing can be achieved using existing technology, and will not be elaborated upon in this solution.

[0027] When this utility model is in use, as shown in the figure, there are four functional boxes 5. In the initial state, there are four different gases in the four functional boxes 5. One of the air inlet pipes 14 corresponds to the connection port 21 on the rotating cylinder 3. At this time, the movable motor 12 also corresponds to one of the functional boxes 5. At this time, the arc-shaped block 15 is located in the arc-shaped opening 13 on the rotating block 7. When the movable motor 12 is started, it can drive the rotating block 7 and the reciprocating screw 19 to rotate. When the reciprocating screw 19 rotates, the connecting frame 20 will drive the piston plate 18 to move closer to the air supply pipe 6. At this time, the gas in the movable chamber 16 will be squeezed into the air inlet pipe 14, enter the rotating cylinder 3 through the connection port 21, and finally enter the target equipment through the air outlet pipe 4.

[0028] When switching is required, the fixed motor 8 starts and drives the gear 9 to rotate. The gear 9, together with the gear ring 10, can drive the rotating cylinder 3 to rotate relative to the fixed sleeve 2, which can drive the arc block 15 and the movable motor 12 and other components to correspond with other functional boxes 5. At this time, repeating the above operation can realize the switching of another gas.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
