[0002] With the continuous development of social economy and the increasing improvement of scientific and technological levels, my country's chip industry is also booming. Wafer cleaning agent, as an organic solvent, can clean wafer chips, thereby removing organic impurities and aqueous impurities on the surface of wafer chips.

[0003] The processes for removing trace water from organic solvents at home and abroad are generally divided into three types: distillation, adsorption separation and extraction. Among them, adsorption separation is the mainstream process for removing trace water. It can adsorb trace water in organic solvents through adsorbents, thereby ensuring the concentration of chemicals in wafer cleaning agents.

[0004] In the prior art, there is an organic solvent dehydration device, which includes a feed pipe, a pretreatment tank, a plurality of adsorption separation tanks and a collection tank, wherein the pretreatment tank is used to pretreat the organic solvent in itself. The feed pipe is connected to the top of the pretreatment tank, and the bottom of the pretreatment tank is connected to the top of one of the adsorption separation tanks through a pipeline. Several adsorption separation tanks are connected end to end through a pipeline. The bottom of the adsorption separation tank farthest from the pretreatment tank is connected to the top of the collection tank through a pipeline. When in use, the organic solvent introduced by the feed pipe is pretreated in the pretreatment tank and then introduced into each adsorption separation tank in turn, so that the adsorbent in each adsorption separation tank adsorbs the water in the organic solvent. After the adsorption is completed, the organic solvent is introduced into the collection tank to complete the dehydration.

[0005] Regarding the above-mentioned related technologies, in order to ensure the dehydration effect of the organic solvent, the existing technology performs multiple adsorption separations on the same organic solvent, so several adsorption separation tanks are set up, which increases the adsorption cost of the organic solvent, so it needs to be improved. Summary of the invention

[0008] By adopting the above technical scheme, compared with the prior art, in order to ensure the dehydration effect of the organic solvent, the same organic solvent is subjected to multiple adsorption separations, so several adsorption separation tanks are set up, thereby increasing the adsorption cost of the organic solvent; the present application sets the vent pipe, the blow pipe and the reflux pipe, so that the nitrogen introduced by the vent pipe can blow out the moisture in the adsorbent in the adsorption separation tank connected to the pretreatment tank, and the nitrogen and the moisture enter into another adsorption separation tank together through the blow-out pipe, so that the other adsorption separation tank vacuum heats the introduced gas and removes moisture, so that the nitrogen after the moisture is removed is passed through the reflux pipe again into the adsorption separation tank connected to the pretreatment tank for recycling, so that there is no need to set up multiple adsorption separation tanks, while ensuring the dehydration effect of the organic solvent, the adsorption cost of the organic solvent is reduced, and the dehydration effect of the organic solvent is also guaranteed.

[0009] Preferably, each of the adsorption separation tanks is provided with a circulation mechanism and a transportation mechanism, and each of the circulation mechanisms includes a circulation pipe, a drying box and a return pipe, one end of the circulation pipe is connected to the corresponding adsorption separation tank, and the other end is connected to the corresponding drying box, the transportation mechanism is used to transport the adsorbent in the corresponding adsorption separation tank to the corresponding circulation pipe, the drying box is used to dry the adsorbent in itself, one end of the return pipe is connected to the corresponding drying box, and the other end is connected to the top of the corresponding adsorption separation tank.

[0010] By adopting the above technical scheme, the circulation mechanism and the transmission mechanism are set up, so that the adsorbent in each adsorption separation tank can be transported to the circulation pipe by the transportation mechanism after the adsorption is completed, and then fall into the drying box through the circulation pipe, so that the drying box dries the adsorbent, thereby regenerating the adsorbent and ensuring that the regeneration of the adsorbent is thorough. The regenerated adsorbent is passed through the return pipe and then into the corresponding adsorption separation tank for recycling, thereby further ensuring the dehydration effect of the organic solvent.

[0011] Preferably, each of the transport mechanisms includes a transport net box, a lifting member, and a dumping assembly. The lifting members are used to drive the corresponding transport net box to move along the height direction of the corresponding adsorption separation tank. The top of the transport net box is opened. The dumping assembly Kim is used to drive the opening direction of the transport net box to change, so that the adsorbent in the corresponding transport net box can pass into the circulation pipe.

[0012] By adopting the above technical solution, the transportation mechanism is set up so that after the adsorption of the adsorbent is completed, the lifting member can drive the transportation net box to move upward, so that the transportation net box is separated from the organic solvent and is located above the organic solvent. At this time, the dumping component drives the direction of the transportation net box to change, so that the transportation net box dumps the adsorbent and allows the adsorbent to enter the circulation pipe, thereby realizing the transportation of the adsorbent, and effectively facilitating the operation of relevant personnel.

[0013] Preferably, each of the transport mechanisms also includes a lifting frame, the lifting parts are used to drive the corresponding lifting frame to move along the height direction of the corresponding adsorption separation tank, the transport net boxes are rotatably connected to the corresponding lifting frame, and the dumping components are used to drive the corresponding transport net boxes to rotate.

[0014] By adopting the above technical solution, the lifting frame is set up so that the lifting parts can drive the lifting frame to move up and down, and when the lifting frame is lifted above the liquid surface of the organic solvent, the pouring component can drive the transport net box to rotate, so that the transport net box will pour the adsorbent, thereby driving the adsorbent, and the lifting and driving steps of the transport net box are carried out separately, which effectively ensures the smooth transportation of the adsorbent and facilitates the operation of relevant personnel.

[0016] By adopting the above technical solution, the net box body and the transfer frame are arranged so that when the transfer frame rotates, the tipping assembly can drive the net box body to slide relative to the transfer frame, so that the net box body is close to one end of the circulation pipe and can be shifted downward and close to the circulation pipe, so that one end of the net box body is close to the circulation pipe, reducing the distance between the net box body and the circulation pipe.

[0018] By adopting the above technical scheme and the specific setting of the tipping assembly, the rotating member can drive the driving frame to rotate through the linkage member while driving the rotating frame to rotate, so that the driving frame drives the transmission frame to displace, and the transmission frame drives the position of one end of the net box body to change, thereby allowing the net box body to slide relative to the transfer frame, thereby realizing the driving of the net box body to slide. At the same time, the driving frame can also prevent the net box body from completely separating from the lifting frame, effectively ensuring the normal operation of the present application.

[0019] Preferably, each linkage member comprises a linkage frame, one end of the linkage frame is rotatably connected to the corresponding transfer frame, and the other end of the linkage frame is rotatably connected to the corresponding driving frame.

[0020] By adopting the above technical solution, the linkage frame is set up so that when the transfer frame rotates, it can drive the linkage frame to move, so that the linkage frame rotates relative to the transfer frame, and then the linkage frame drives the drive frame to rotate, thereby realizing the linkage between the transfer frame and the drive frame, effectively saving the active components of the rotating drive frame, and facilitating the operation of relevant personnel.

[0021] Preferably, each of the net box bodies has an opening at one end close to the corresponding circulation pipe, and a grid is arranged in the opening of the net box body. The top of the grid is rotatably connected to the corresponding net box body, and the grid is used to close the opening of the corresponding net box body. Each of the transport mechanisms also includes an abutment frame, which is arranged on the inner wall of the corresponding adsorption separation tank and is located on the displacement path of the bottom of the corresponding grid.

[0022] By adopting the above technical solution, the abutment frame and the grid frame are arranged so that when the net box body gradually approaches the abutment frame, when the net box body moves to the specified position, the abutment frame and the grid frame abut against each other, and then the grid frame can be rotated, and the opening on the net box body can be opened, so that the adsorbent in the net box body can roll out of the net box body through the opening, thereby reducing the probability of the adsorbent accidentally escaping from the net box body in other states, and ensuring the transportation effect of the adsorbent.

[0023] Preferably, abutment portions are further extended upward from the bottom of each mesh box body, and the abutment portions are located on a side of the corresponding mesh frame close to the corresponding abutment frame, and abut against the bottom of the corresponding mesh frame.

[0024] By adopting the above technical solution, the abutment portion is set so that the abutment portion can limit the grid by abutting against the bottom of the grid, thereby reducing the probability of the grid rotating relative to the grid box body under its own gravity when the grid box body is tilted, thereby ensuring the sealing effect of the opening on the grid box body.

The circulation mechanism and the transmission mechanism are arranged so that the adsorbent in each adsorption separation tank can be transported to the circulation pipe by the transportation mechanism after the adsorption is completed, and then fall into the drying box through the circulation pipe, so that the drying box dries the adsorbent, thereby regenerating the adsorbent and ensuring that the adsorbent is regenerated thoroughly. The regenerated adsorbent is passed through the return pipe and then into the corresponding adsorption separation tank again for recycling, thereby further ensuring the dehydration effect of the organic solvent; 3.

[0041] The implementation principle of an organic solvent dehydration device in Example 1 of the present application is as follows: the nitrogen introduced through the ventilation pipe 32 can blow out the moisture in the adsorbent in the adsorption separation tank 3 connected to the pretreatment tank 2, and allow the nitrogen and moisture to enter another adsorption separation tank 3 through the blow-out pipe 31, so that the other adsorption separation tank 3 vacuum heats the introduced gas and removes moisture, so that the nitrogen after the moisture is removed is introduced again into the adsorption separation tank 3 connected to the pretreatment tank 2 through the reflux pipe 33 for recycling, thereby eliminating the need to set up multiple adsorption separation tanks 3.

The abutment portion 6311 is located on the side of the net frame 67 close to the docking frame 61, and the top end is higher than the bottom end of the net frame 67, and abuts against the side wall of the net frame 67 to prevent the bottom end of the net frame 67 from rotating in the direction close to the docking frame 61. In the embodiment of the present application, a torsion spring is also provided on the net frame 67, and the torsion spring is used to reset the net frame 67 and continuously abut against the abutment frame 68 to ensure the sealing effect of the end opening of the net box body 631.

[0053] Reference Figure 3 and Figure 4The tipping assembly 65 includes a rotating member 651, a driving frame 652, a transmission frame 653 and a linkage member 654. In the embodiment of the present application, the number of the rotating member 651, the transmission frame 653 and the linkage member 654 is set to two, and correspondingly, the two transmission frames 653 are respectively located on both sides of the net box body 631 along its own width direction. The driving frame 652 is located on the side of the net box body 631 close to the docking frame 61, and is rotatably connected to the top of the lifting frame 62 through a pin shaft, and the rotation axis is set parallel to the rotation axis of the intermediate transfer frame 632.

[0054] Reference Figure 3 and Figure 4 The bottom end of the driving frame 652 extends downward and is lower than the top end of the net box body 631 to reduce the probability of accidental slippage of the net box body 631. The two transmission frames 653 are respectively mounted on the two ends of the driving frame 652 along the width direction of the net box body 631, and are both slidably connected to the driving frame 652, and the sliding direction is the width direction of the driving frame 652. Each transmission frame 653 is rotatably connected to one end of the net box body 631 close to the docking frame 61 through a pin shaft.

[0055] Reference Figure 3 and Figure 4 Each linkage member 654 includes a linkage frame 6541, and the two linkage frames 6541 are respectively located on both sides of the net box body 631 along its own width. One end of each linkage frame 6541 is rotatably connected to the corresponding transfer frame 632 through a pin shaft, and the rotation axis of the transfer frame 632 itself is not the same as the rotation axis between itself and the linkage frame 6541. The other end of each linkage frame 6541 is rotatably connected to the driving frame 652 through a pin shaft, and the rotation connection with the driving frame 652 is located above the corresponding transmission frame 653.

[0056] Reference Figure 3 and Figure 4 The transport mechanism 6 also includes an abutment frame 68, which is located on the upper side of the docking frame 61, and one end of the abutment frame 68 is fixedly connected to the inner wall of the adsorption separation tank 3, and the other end extends toward the direction close to the net box body 631. The abutment frame 68 is located on the displacement path of the net frame 67.

[0057] Reference Figure 2 , Figure 3 and Figure 4 In the initial state, the net box body 631 is located in the liquid surface of the organic solvent in the adsorption separation tank 3. At this time, the top of the net box body 631 is vertically arranged upward, and the net box body 631 is located on the side of its own sliding path farthest from the docking frame 61 relative to the transfer frame 632. When the lifting member 64 drives the lifting frame 62 and the transport net box 63 to rise and thus separate from the liquid surface, when the transport net box 63 is raised to a specified height, the rotating member 651 drives the transfer frame 632 to rotate.

[0058] Reference Figure 3 and Figure 4 During this process, the linkage frame 6541 on the transfer frame 632 rotates relative to the transfer frame 632, so that the transfer frame 632 drives the driving frame 652 to rotate, and then the transmission frame 653 on the driving frame 652 is displaced relative to the driving frame 652, and then the transmission frame 653 drives the net box body 631 to slide relative to the transfer frame 632, so that the net box body 631 gradually approaches the docking frame 61.

[0059] Reference Figure 2 , Figure 3 and Figure 4 As the net box body 631 gradually approaches the docking frame 61, the net frame 67 gradually abuts against the abutting frame 68, thereby pushing the net frame 67 to rotate. At this time, the net frame 67 opens the opening on the net box body 631, so that the adsorbent in the net box body 631 falls onto the docking frame 61 through the opening, and finally falls into the circulation pipe 51. When the end of the net box body 631 abuts against the inner top wall of the docking frame 61, the transfer frame 632 stops rotating, so that the adsorbent continues to fall onto the docking frame 61 and finally falls into the circulation pipe 51.

[0060] The implementation principle of an organic solvent dehydration device in Example 2 of the present application is as follows: after the adsorption of the adsorbent is completed, the lifting member 64 drives the transport net box 63 to leave the liquid surface, and thereafter, the dumping assembly 65 drives the transport net box 63 to move, so that the adsorbent in the transport net box 63 rolls onto the docking frame 61, and enters the drying box 52 through the circulation pipe 51 for drying. After drying, the extraction pump 54 draws the regenerated adsorbent into the return pipe 53, and through the return pipe 53 and the through pipe 34, it falls back into the opening of the net box body 631 for reuse.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
