Description

Technical Field

[0001] The utility model relates to the technical field of gas configuration control, in particular to a mixed gas configuration switching device. Background Art

[0002] A catalyst is a substance that increases the rate of a reaction without changing the overall standard Gibbs free energy of the reaction. Catalysts can be solid, liquid, or gaseous. Gas catalysts often participate in the mixing of different gases.

[0003] A mixed gas primarily refers to a gas containing two or more active components, or a non-active component whose content exceeds a specified limit. Mixtures of several gases are commonly used working fluids in engineering, and mixed gases are often studied as ideal gases.

[0004] The patent document with announcement number CN217594327U discloses a mixed gas configuration switching device that can conveniently input different gases into the interior of a pressure tank for mixing by setting up multiple air intake mechanisms. The different gases will eventually be discharged into the interior of the pressure tank through the output air nozzle. When the output air nozzle is driven up and down inside the pressure tank by the extension and contraction of the electric telescopic rod, different gases can be switched and input into different heights inside the pressure tank for mixing, thereby avoiding stratification and insufficient mixing caused by the input of gases of different densities into the pressure tank.

[0005] However, in the process of implementing the above technical solution, it was found that the above technical solution had the following technical problems:

[0006] The existing mixed gas configuration switching device can support the input of different gases into the interior of the pressure tank by using multiple air intake structures to support the gas mixing work. When switching the input of different gases, the output gas nozzle is driven up and down by an electric telescopic rod to control it. However, in actual application, the internal space of the pressure tank needs to be developed for use, which is not conducive to replacing the actuator after damage. Utility Model Content

[0007] In order to overcome the shortcomings of the existing mixed gas configuration switching device in actual application, which requires the development of the internal space of the pressure tank for use, and is not conducive to the replacement and use of the executing components after damage, the embodiment of the present application provides a mixed gas configuration switching device, by processing multiple movable slots A inside the mixing tank cover and multiple movable slots B inside the switching disk, when the multiple movable slots B and the multiple movable slots A on the switching disk cooperate to accommodate multiple main operating arms, one end of the main operating arm can be supported by a positioning ball head to rotate inside the movable slot B, so as to support the main operating arm to control the opening and closing of the space in the venting channel through the circular hole processed at the other end, thereby controlling the gas from the inside of the gas pipe connected to the connecting port, through the collecting disk and the venting channel to the inside of the mixing tank body for mixing. It is easy to operate, and because the multiple main operating arms are exposed to the outside of the mixing tank body, it is only necessary to remove the mixing tank cover as a whole during maintenance and replacement.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0009] A mixed gas configuration switching device includes a switching disk, a mixing tank cover and a summing disk, wherein a plurality of venting channels are machined inside the switching disk;

[0010] The summing disc is assembled on the top of the mixing tank cover, and the switching disc is pressed against the inside of the mixing tank cover;

[0011] The bottom of the mixing tank cover is assembled and connected to the mixing tank body, and the top of the collecting plate is assembled and connected to multiple pipe ports, one end of each of the pipe ports corresponds to a plurality of venting channels, and the other end of each of the pipe ports is connected to an air supply pipe, so that the gas is transported to the interior of the mixing tank body through the collecting plate and the venting channels for mixing;

[0012] The interior of the mixing tank cover is processed with a plurality of movable notches A, and the interior of the switching disk is processed with a plurality of movable notches B. The plurality of movable notches A and the plurality of movable notches B are used in combination and are equally spaced around the center of the switching disk. The movable notches B are connected to one end of the movable notch A close to the center of the switching disk, so that the cross-section of the movable notch A and the switching disk is fan-shaped. A main operating arm is commonly provided inside the movable notch A and the switching disk.

[0013] Among them, multiple deflation channels respectively pass through the interior of multiple movable slots B, one end of the main operating arm is processed with a circular hole, and the end extends into the interior of the movable slot B and remains in contact with its inner wall. One end of the main operating arm rotates inside the movable slot B to control the connection state between the circular hole and the interior of the deflation channel.

[0014] In one possible implementation, the top surface and bottom surface of the main operating arm near one end of the circular hole are integrally formed with a positioning ball head, and the top and bottom inner walls of the multiple movable slots B are processed with ball grooves adapted to the positioning ball head to support one end of the main operating arm to rotate around the positioning ball head inside the movable slot B.

[0015] In one possible implementation, a secondary operating arm is provided inside one end of the main operating arm, and the secondary operating arm is located at the end of the main operating arm away from the center of the switching disk. One end of the secondary operating arm extends from the inside of the movable slot A, and the other end controls the movement of the main operating arm inside the movable slot B inside the movable slot A.

[0016] In a possible implementation, a receiving slot is machined inside one end of the main operating arm, one end of the auxiliary operating arm is movably connected inside the receiving slot, and a circular groove is machined inside the other end of the auxiliary operating arm.

[0017] In a possible implementation, the cross-sections of the receiving slot and one end of the auxiliary operating arm are both trapezoidal, and the inclined surface of the auxiliary operating arm fits against the inclined inner wall of the receiving slot.

[0018] In one possible implementation, one end of the auxiliary operating arm moves inside the receiving slot toward the end away from the center of the switching disk. When one end of the auxiliary operating arm withdraws from the inside of the auxiliary operating arm to one end, the auxiliary operating arm moves from the bottom to the top inside the receiving slot.

[0019] In one possible implementation, a limit head is processed on the bottom surface of one end of the auxiliary operating arm, and movable strip grooves are processed on the bottom inner walls on both sides of the multiple movable slots A. One end of the auxiliary operating arm slides inside the storage slot toward the end close to the center of the switching disk, so that the limit head extends into the interior of the movable strip groove, so that the auxiliary operating arm limits the movement of one end of the main operating arm inside the movable slot B.

[0020] The beneficial effects of this application are:

[0021] First, in this solution, multiple movable notches A are machined inside the mixing tank cover, and multiple movable notches B are machined inside the switching disk. When the multiple movable notches B on the switching disk cooperate with the multiple movable notches A to accommodate multiple main operating arms, one end of the main operating arm can be supported by a positioning ball head to rotate inside the movable notch B, so as to support the main operating arm to control the opening and closing of the space in the degassing channel through the circular hole machined at the other end, thereby controlling the state in which gas is transported from the inside of the gas pipeline connected to the connecting port through the collecting disk and the degassing channel to the inside of the mixing tank body for mixing. This makes operation easy, and because the multiple main operating arms are exposed to the outside of the mixing tank body, it is only necessary to remove the mixing tank cover as a whole for maintenance and replacement.

[0022] Secondly, in this solution, by controlling the movement of the auxiliary operating arm inside the storage slot, one end of the auxiliary operating arm can be controlled to withdraw from or extend into the inside of the movable slot A, and the other end of the auxiliary operating arm can be synchronously moved up and down inside the storage slot. When the limit head at the bottom of the auxiliary operating arm is extended into the inside of the movable strip slot, the movement of the main operating arm inside the movable slot A can be restricted, and the state of the circular hole on the main operating arm controlling the opening and closing of the internal channel of the air release channel can be maintained. When the limit head withdraws from the inside of the movable strip slot, the auxiliary operating arm can be used to control the main operating arm to rotate around the positioning ball head, and the circular hole on the main operating arm can be used to control the opening and closing of the internal channel of the air release channel.

[0031] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0032] Example 1:

[0033] This embodiment introduces a specific structure of a mixed gas configuration switching device. Figure 1-Figure 5As shown, it includes a switching disk 9 with multiple air release channels 12 processed inside, a mixing tank cover 1 and a summarizing disk 3. The bottom of the mixing tank cover 1 is assembled and connected to the mixing tank body 5, and the top of the summarizing disk 3 is assembled and connected to multiple pipe ports 2. The mixing tank cover 1 is internally processed with multiple movable notches A4, and the switching disk 9 is internally processed with multiple movable notches B10. The multiple movable notches A4 and the multiple movable notches B10 are used in combination and are evenly spaced around the center of the switching disk 9.

[0034] The collecting plate 3 is assembled on the top of the mixing tank cover 1 by using bolts. When the switching plate 9 is pressed into the interior of the mixing tank cover 1, one end of the multiple pipe ports 2 corresponds to the multiple air release channels 12 one by one, ensuring that the interiors of the multiple pipe ports 2 and the interiors of the multiple air release channels 12 are respectively connected, so as to support the other ends of the multiple pipe ports 2 to be connected to the air supply pipe, so that the gas is transported to the interior of the mixing tank body 5 through the collecting plate 3 and the air release channels 12 for mixing;

[0035] Secondly, by connecting the movable slot B10 to one end of the movable slot A4 close to the center of the switching disk 9, the cross-sections of the movable slot A4 and the switching disk 9 are fan-shaped. When a main operating arm 8 is provided inside the movable slot A4 and the switching disk 9, a circular hole is machined at one end of the main operating arm 8. On the basis of the multiple degassing channels 12 passing through the multiple movable slots B10 respectively, one end of the main operating arm 8 with the machined circular hole is extended into the interior of the movable slot B10 and kept in contact with the inner wall thereof. In this state, one end of the main operating arm 8 can be controlled to rotate inside the movable slot B10 to control the communication state between the circular hole and the interior of the degassing channel 12, so as to realize the function of opening or cutting off the internal passage of the degassing channel 12.

[0036] Furthermore, in order to ensure that the main operating arm 8 can be inside the movable notch B10, the circular hole is used to stably control the opening and closing of the space in the air release channel 12, such as Figure 5 As shown, the top surface and bottom surface of the main operating arm 8 near one end of the circular hole are integrally formed with a positioning ball head 15. By processing ball grooves that are compatible with the positioning ball head 15 on the top and bottom inner walls of multiple movable notches B10, when one end of the positioning ball head 15 is adapted to the inside of the ball groove, one end of the main operating arm 8 can be supported to rotate around the positioning ball head 15 inside the movable notch B10.

[0037] The above-mentioned design processes multiple movable slots A4 inside the mixing tank cover 1 and multiple movable slots B10 inside the switching disk 9. When the multiple movable slots B10 and the multiple movable slots A4 on the switching disk 9 cooperate to accommodate multiple main operating arms 8, the positioning ball head 15 can be used to support one end of the main operating arm 8 to rotate inside the movable slot B10, so as to support the main operating arm 8 to control the space inside the venting channel 12 through the circular hole processed at the other end thereof, thereby controlling the gas from the inside of the gas pipe connected to the connecting port 2, through the collecting disk 3 and the venting channel 12 to the inside of the mixing tank body 5 for mixing. It is easy to operate, and because the multiple main operating arms 8 are exposed to the outside of the mixing tank body 5, when repairing and replacing, it is only necessary to remove the mixing tank cover 1 as a whole.

[0038] Example 2:

[0039] Based on Example 1, this example introduces the specific structure of the main operating arm 8. Figures 2 to 7 As shown, a secondary operating arm 6 is provided inside one end of the main operating arm 8, and a receiving notch 7 is processed inside one end of the main operating arm 8.

[0040] The auxiliary operating arm 6 is located at the end of the main operating arm 8 away from the center of the switching plate 9. By movably connecting one end of the auxiliary operating arm 6 to the inside of the receiving slot 7 and extending one end of the auxiliary operating arm 6 from the inside of the movable slot A4, the one end of the auxiliary operating arm 6 can be placed inside the movable slot A4 to control the movement of the main operating arm 8 inside the movable slot B10.

[0041] At the same time, a circular groove 11 is machined inside one end of the auxiliary operating arm 6, and the circular groove 11 is located at the end away from the center of the switching disk 9, which can provide a support point for the operator to control the auxiliary operating arm 6, thereby ensuring an anti-slip effect;

[0042] Secondly, by making the cross-sections of the receiving slot 7 and one end of the auxiliary operating arm 6 both trapezoidal, the inclined surface of the auxiliary operating arm 6 is fitted with the inclined inner wall of the receiving slot 7. When one end of the auxiliary operating arm 6 moves inside the receiving slot 7 toward the end away from the center of the switching disk 9, the support is guided by the inclined surface, so that on the one hand, the one end of the auxiliary operating arm 6 withdraws from the inside of the auxiliary operating arm 6 to one end, and on the other hand, the auxiliary operating arm 6 moves from the bottom to the top inside the receiving slot 7.

[0043] Furthermore, in order to limit the movement of the main operating arm 8 in the movable notch A4, the opening and closing state between the circular hole at one end of the main operating arm 8 and the switching disk 9 is kept stable, as shown in FIG. Figure 3 、 Figure 6 and Figure 7As shown, a limit head 13 is processed on the bottom surface of one end of the auxiliary operating arm 6, and movable strip grooves 14 are processed on the bottom inner walls on both sides of multiple movable slots A4. By making one end of the auxiliary operating arm 6 slide inside the storage slot 7 toward the end close to the center of the switching disk 9 (the control power of the auxiliary operating arm 6 can come from its own gravity), when the limit head 13 extends into the inside of the movable strip groove 14, the auxiliary operating arm 6 can limit the movement of one end of the main operating arm 8 inside the movable slot B10, keeping the main operating arm 8 in a fixed state inside the movable slot A4.

[0044] The above design controls the auxiliary operating arm 6 to move in the direction away from the center of the switching disk 9 inside the receiving slot 7. When one end of the auxiliary operating arm 6 withdraws from the inside of the movable slot A4, the other end of the auxiliary operating arm 6 can be simultaneously moved toward the top inside the receiving slot 7, so that the limit head 13 at the bottom of the auxiliary operating arm 6 withdraws from the inside of a movable groove 14 on the inner wall of the bottom of the target movable slot A4, thereby supporting the auxiliary operating arm 6 to control the main operating arm 8 to rotate around the positioning ball head 15, and utilizing the circular hole on the main operating arm 8 to control the opening and closing of the internal channel of the degassing channel 12;

[0045] At the same time, when the auxiliary operating arm 6 is moved inside the receiving slot 7 toward the center of the switching disk 9 by means of its own gravity, one end of the auxiliary operating arm 6 can be retracted as much as possible into the inside of the movable slot A4 (the circular slot 11 needs to be partially exposed to the outside of the mixing tank cover 1), and the other end of the auxiliary operating arm 6 enters the inside of the receiving slot 7 and moves toward the bottom, so that the limit head 13 at the bottom of the auxiliary operating arm 6 is inserted into another movable strip groove 14 at the bottom inside the target movable slot A4, so as to limit the movement of the main operating arm 8 inside the movable slot A4 and keep the circular hole on the main operating arm 8 controlling the opening and closing of the internal channel of the degassing channel 12.

[0046] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
