[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a rotatable chemical reagent storage rack, which has the following beneficial effects:

[0015] 1. The rotatable chemical reagent storage rack controls the connection between the air inlet branch pipe and the limit suction cup through a three-way switch valve, so that the external vacuum equipment drives the air in the contact area between the limit suction cup and the chemical reagent to be output through the side branch exhaust pipe. As the air is discharged from the contact surface between the limit suction cup and the chemical reagent, vacuum suction is generated between the two. The chemical reagent is fixed to the limit suction cup under the action of the vacuum suction.

The supporting structure and the synchronous structure reduce the gravity transmission of the chemical reagent adsorbed by the internal limiting suction cup of the placement tray, effectively improving the carrying capacity of the device, greatly increasing the upper limit of the weight of the chemical reagent that the device can withstand, and thus enhancing the practicability of the device.

[0017] 3. The rotatable chemical reagent storage rack rotates the air guide cover along the rotary joint through the air intake branch pipe. The air intake branch pipe drives the chemical reagent to rotate through the limit suction cup. During the rotation of the chemical reagent, the personnel take and put the chemical reagent, and after the personnel determine the corresponding chemical reagent, the three-way switch valve is used to control the air intake branch pipe to be connected to the outside. The external air enters the limit suction cup through the air intake branch pipe, and then separates the limit suction cup from the chemical reagent, which effectively increases the carrying capacity of the device, greatly enhances the convenience of device operation, and thus enhances the applicability of the device.

The personnel take and put the test, and after determining the corresponding chemical reagent, the personnel control the air intake branch pipe 6 to be connected with the outside through the three-way switch valve 7, and the external air enters the limit suction cup 8 through the air intake branch pipe 6, and then separates the limit suction cup 8 from the chemical reagent, which effectively improves the carrying capacity of the device, greatly enhances the convenience of device operation, and thus enhances the applicability of the device. The middle part of each group of air intake branch pipes 6 is connected with a three-way switch valve 7, and the air intake branch pipe 6 is controlled to be connected with the limit suction cup 8 through the three-way switch valve 7, so that the external vacuum equipment drives the air in the contact area of ​​the limit suction cup 8 and the chemical reagent to be output through the side branch exhaust pipe 2.

The eccentric stress applied to the chemical reagent during the rotation process is transmitted and reduced by the limiting suction cup 8, thereby reducing the probability of the chemical reagent on the device being detached and improving the firmness of the chemical reagent on the device. The input end of each group of air intake branch pipes 6 is connected to the limiting suction cup 8, and the outer surface of each group of limiting suction cups 8 is fixedly installed with a placement tray 9 through a nut. The top of each group of air guide hoods 5 is connected to an extension pipe 10, and the outer surface of each group of extension pipes 10 is provided with a lifting frame 11. The outer surface of each group of placement trays 9 is fixedly connected to the outer surface of the corresponding lifting frame 11 A reinforcing arc plate 19 is provided between two groups of adjacent placement trays 9. Through the air intake branch pipe 6, the lifting frame 11 and the reinforcing arc plate 19, the reinforcing arc plate 19 fixes multiple groups of placement trays 9 in series into a synchronous structure, and the air intake branch pipe 6 and the lifting frame 11 respectively form a supporting structure at the bottom and inner side of the placement tray 9. The supporting structure and the synchronous structure reduce the gravity transmission of the chemical reagent adsorbed by the internal limiting suction cup 8 of the placement tray 9, effectively improve the carrying capacity of the device, greatly enhance the upper limit of the weight of the chemical reagent borne by the device, thereby enhancing the practicability of the device, and the top end of the upper extension tube 10 is fixed with a sealing cover plate 12 by bolts and nuts.

[0024] In the utility model, in order to reduce the impact of the device on the external vacuum equipment, the input end of each group of three-way switch valves 7 is connected to a switch tube 13, and the input end of each group of switch tubes 13 is provided with a filter 14 for reducing the number of dust particles in the air entering the device, thereby reducing the impact of the device on the external vacuum equipment.

[0025] In the utility model, in order to reduce the number of dust particles on the surface of the chemical reagent on the device, an overhead rod 15 is provided on the top of the sealing cover plate 12, and a dust cover 16 is provided on the top of the overhead rod 15 for separating some dust particles from the chemical reagent, thereby reducing the number of dust particles on the surface of the chemical reagent on the device.

[0027] In the utility model, in order to reduce the vibration amplitude of the chemical reagents on the device during the movement, the inner wall of each group of trays 9 is provided with an embedded buffer pad 18 which buffers and reduces the impact stress through its own elastic deformation, and the bottom of each group of embedded buffer pads 18 is provided with a process hole for the limiting suction cup 8 to be inserted, thereby reducing the vibration amplitude of the chemical reagents on the device during the movement.

[0028] In the utility model, in order to extend the effective service life of the device, an anti-corrosion coating for reducing the rust rate is provided on the surface of each group of air guide hood 5, air intake branch pipe 6, placement tray 9, extension pipe 10, lifting frame 11, reinforcing arc plate 19, supporting base 1, side branch exhaust pipe 2 and sealing cover plate 12, thereby extending the effective service life of the device.

[0029] When in use, first place the device in the placement position. After the device is placed firmly, place the chemical reagent in the placement tray 9, and the bottom of the chemical reagent fits with the adsorption end of the limit suction cup 8. Then, the three-way switch valve 7 is used to control the air intake branch pipe 6 to be connected with the limit suction cup 8. The external vacuum equipment drives the air in the contact area of ​​the limit suction cup 8 and the chemical reagent to enter the air guide cover 5 through the air intake branch pipe 6. The air in the air guide cover 5 enters the side branch exhaust pipe 2 through the rotary joint 4 and the extension pipe 10. The air in the side branch exhaust pipe 2 enters the external vacuum equipment. As the air is discharged from the contact surface between the limit suction cup 8 and the chemical reagent, vacuum suction is generated between the two. The chemical reagent is fixed to the limit suction cup 8 under the action of the vacuum suction. At the same time, the arc plate 19 is strengthened to fix multiple groups of placement trays 9 in series to form a synchronous structure. The support structure and the synchronous structure will reduce the gravity transfer of the chemical reagent adsorbed by the internal limit suction cup 8 of the placement tray 9, and then the device will perform standby operation. When it is necessary to select the chemical reagents on the device, the air guide cover 5 is first driven to rotate along the rotary joint 4 through the air intake branch pipe 6, and the air intake branch pipe 6 drives the chemical reagents to rotate through the limit suction cup 8. During this process, the eccentric stress on the chemical reagents is transmitted and reduced by the limit suction cup 8. During the rotation of the chemical reagents, the personnel will take and put the chemical reagents. After the personnel determine the corresponding chemical reagents, the three-way switch valve 7 is used to control the air intake branch pipe 6 to be connected to the outside, and the external air enters the limit suction cup 8 through the air intake branch pipe 6, thereby separating the limit suction cup 8 from the chemical reagents.

[0030] In summary, the rotatable chemical reagent storage rack controls the connection between the air inlet branch pipe 6 and the limit suction cup 8 through the three-way switch valve 7, so that the external vacuum equipment drives the air in the contact area between the limit suction cup 8 and the chemical reagent to be output through the side branch exhaust pipe 2. As the air is discharged from the contact surface between the limit suction cup 8 and the chemical reagent, vacuum suction is generated between the two. The chemical reagent is fixed to the limit suction cup 8 under the action of the vacuum suction. The eccentric stress applied to the chemical reagent during the rotation process is transmitted and reduced by the limit suction cup 8, thereby reducing the probability of the chemical reagent on the device being detached and improving the firmness of the chemical reagent on the device.

[0031] The rotatable chemical reagent storage rack uses the air intake branch pipe 6, the lifting frame 11 and the reinforcing arc plate 19, so that the reinforcing arc plate 19 fixes multiple groups of placement trays 9 in series into a synchronous structure, and the air intake branch pipe 6 and the lifting frame 11 respectively form support structures at the bottom and inner side of the placement tray 9. The support structure and the synchronous structure reduce the gravity transmission of the chemical reagent adsorbed by the internal limiting suction cup 8 of the placement tray 9, effectively improving the carrying capacity of the device, greatly increasing the upper limit of the weight of the chemical reagent that the device can withstand, and thus enhancing the practicability of the device.

[0032] The rotatable chemical reagent storage rack rotates the air guide hood 5 along the rotary joint 4 through the air intake branch pipe 6. The air intake branch pipe 6 drives the chemical reagent to rotate through the limit suction cup 8. The chemical reagent is taken and placed by personnel during rotation. After the personnel determines the corresponding chemical reagent, the three-way switch valve 7 is used to control the air intake branch pipe 6 to be connected to the outside. The external air enters the limit suction cup 8 through the air intake branch pipe 6, and then the limit suction cup 8 is separated from the chemical reagent, which effectively increases the carrying capacity of the device, greatly enhances the convenience of device operation, and thus enhances the applicability of the device.
