Description

Technical Field

[0001] The utility model relates to the technical field of organic solvent transfer processing, and particularly relates to a device for transferring materials between two kettles. Background Technique

[0002] The organic solvents of photoresist mainly include toluene, xylene, chlorinated hydrocarbons, butyl acetate, acetone, etc. These solvents play a crucial role in the liquid components of photoresist. They not only affect the solubility, coating performance and drying speed of photoresist, but also are selected considering various factors such as the type of photoresist, process requirements and environmental factors.

[0003] Currently, the processing procedures of organic solvents containing photoresist need to be completed successively through a mixing kettle and a reaction kettle. There are the following problems in the transfer process of organic solvents:

[0004] 1. Usually, the feeding and discharging of a single kettle are relatively simple, but the material transfer between different kettles requires manual intervention, and material loss is likely to occur during the manual intervention process, thus affecting the subsequent product quality;

[0005] 2. During the process of manual material transfer, the operation steps of personnel are increased, the labor intensity is high, and at the same time, the operator may come into contact with the material, which may cause personal injury to the operator;

[0006] 3. Manual operation for material transfer will greatly increase the production cycle and affect the production efficiency;

[0007] 4. When feeding materials through the feeding port currently, the materials will splash on the inner side of the kettle cover and near the feeding port, and there is a lack of automatic cleaning means in the prior art, so subsequent disassembly and cleaning are required, which is not convenient enough;

[0008] In summary, the above problems exist in the process of transferring and injecting organic solvents between two kettles and need to be solved urgently. Content of the Utility Model

[0009] The purpose of the utility model is to solve the problems raised in the above background technique, and then a device for transferring materials between two kettles is proposed.

[0010] The technical solution adopted by the utility model to solve its technical problems is:

[0011] A device for material transfer between two reactors, comprising a mixing reactor body, a reaction reactor body and a spray cleaning assembly. Stirring assemblies are provided inside both the mixing reactor body and the reaction reactor body. The spray cleaning assembly includes a spray head, and also includes a feed pipe, a suction pump, a discharge pipe, a liquid outlet pipe, a first conveying assembly, a second conveying assembly, a third conveying assembly, a feeding pipe, a spray pipe and a splash-proof cover with an umbrella-shaped main body. The suction pump is arranged between the mixing reactor body and the reaction reactor body;

[0012] The discharge pipe is communicated with the discharge port of the mixing reactor body;

[0013] The liquid outlet pipe is communicated with the discharge port of the reaction reactor body;

[0014] The feed pipe, the suction pump and the discharge pipe are connected and communicated through the first conveying assembly;

[0015] The second conveying assembly is communicated with the suction pump;

[0016] Two groups of third conveying assemblies are respectively arranged on the mixing reactor body and the reaction reactor body, and the third conveying assembly is communicated with the second conveying assembly;

[0017] The feeding pipe and the spray pipe are both communicated with the third conveying assembly, and one ends of the two feeding pipes are respectively inside the mixing reactor body and the reaction reactor body;

[0018] The spray cleaning assembly is connected to the spray pipe, and the spray heads are respectively inside the mixing reactor body and the reaction reactor body;

[0019] Two splash-proof covers are respectively arranged inside the mixing reactor body and the reaction reactor body, and are respectively adapted to the sizes of the kettle covers of the mixing reactor body and the reaction reactor body to form a barrier;

[0020] The feeding pipe and the spray head both pass through the splash-proof cover and one end of the feeding pipe is lower than the spray head. The stirring assembly passes through the center of the splash-proof cover and is rotatably connected thereto.

[0021] Further, the first conveying assembly includes a first-level three-way pipe and a first solenoid valve,

[0022] The first-level three-way pipe is respectively communicated with the feed pipe, the suction pump and the discharge pipe;

[0023] Three first solenoid valves are respectively arranged on the three pipelines of the first-level three-way pipe and are independently controlled.

[0024] Further, the second conveying assembly includes a second-level three-way pipe and a second solenoid valve,

[0025] One of the pipelines of the second-level three-way pipe is communicated with the suction pump;

[0026] Three second solenoid valves are respectively arranged on the three pipelines of the second-level three-way pipe and are independently controlled.

[0027] Further, the third conveying assembly includes a three-stage three-way pipe, a third solenoid valve, and a conveying pipe.

[0028] Two three-stage three-way pipes are respectively arranged on the main body of the mixing kettle and the main body of the reaction kettle.

[0029] Three third solenoid valves are respectively arranged on three pipelines of the three-stage three-way pipe and are independently controlled.

[0030] One of the pipelines of the three-stage three-way pipe is communicated with the conveying pipe, and one ends of the two conveying pipes are respectively communicated with the remaining two pipelines of the two-stage three-way pipe.

[0031] The remaining two pipelines of the three-stage three-way pipe are respectively communicated with the feeding pipe and the spray pipe.

[0033] Further, several convex folds are formed by the upward protrusion on the inner side of the anti-spraying cover. The convex folds are distributed around the circumference of the anti-spraying cover, and concave folds are formed between adjacent convex folds.

[0034] The above scheme increases the surface area of the anti-spraying cover, which helps to disperse the organic solvent and avoid its accumulation in a specific area.

[0035] Further, the upper surface of the convex fold has a peak extending radially, and the peak is inclined with the outer side higher and the inner side lower.

[0036] The above scheme helps to further guide the organic solvent to flow along the inner surface of the anti-spraying cover, reduces its residence time in the anti-spraying cover, and further reduces the amount of the organic solvent attached to the anti-spraying cover.

[0037] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0038] During the transfer and processing of the organic solvent containing photoresist in the mixing kettle and the reaction kettle of the present device, no manual intervention is required, the labor intensity is reduced, and there will be no material loss. During this process, the potential safety hazard of manual accidental contact with the organic solvent is also significantly reduced. The production cycle of the organic solvent is strictly and accurately controlled, thereby improving the production efficiency. In addition, through the umbrella-shaped anti-spraying cover, the phenomenon that the organic solvent splashes on the inner side of the kettle cover and near the feeding port during the process of transferring and adding the material into the kettle can be significantly reduced. No disassembly and cleaning are required later, and the automatic cleaning process of the organic solvent attached to the side wall of the kettle body and the surface of the anti-spraying cover can be realized through the spray cleaning assembly.

[0055] For further refinement of the solution of the embodiment of the present utility model, as Figure 1 shown, the first conveying assembly includes a first-level three-way pipe 7 and a first solenoid valve 8,

[0056] The first-level three-way pipe 7 is respectively communicated with the feed pipe 1, the suction pump 4, and the discharge pipe 5;

[0062] Two three-way pipes of the third level 12 are respectively arranged on the mixing kettle body 2 and the reaction kettle body 3;

[0063] Three third solenoid valves 13 are respectively arranged on the three pipelines of the three-way pipe of the third level 12 and are independently controlled;

[0064] One of the pipelines of the three-way pipe of the third level 12 is communicated with the conveying pipe 11, and one ends of the two conveying pipes 11 are respectively communicated with the remaining two pipelines of the two-way pipe of the second level 9;

[0065] The remaining two pipelines of the three-way pipe of the third level 12 are respectively communicated with the feeding pipe 14 and the spraying pipe 15.

[0066] It should be noted that the suction pump 4, the first solenoid valve 8, the second solenoid valve 10, the third solenoid valve 13 and the stirring assembly are all electrically connected to the controller, and the controller is not shown in the figure.

[0067] The working process of the present utility model:

[0068] First, an organic solvent containing photoresist is conveyed through the feeding pipe 1 (injected into the feeding pipe 1 through an adjusting pump, and the adjusting pump is not shown in the figure and belongs to the prior art without improvement). At this time, the controller controls the first solenoid valve 8 on the right pipeline of the one-way pipe of the first level 7 to close, and the first solenoid valves 8 on the upper and lower pipelines are opened and the suction pump 4 works. At the same time, the second solenoid valves 10 on the lower and right pipelines of the two-way pipe of the second level 9 are opened, and the second solenoid valve 10 on the left pipeline of the two-way pipe of the second level 9 is closed. In addition, the third solenoid valves 13 on the upper and left pipelines of the three-way pipe of the third level 12 are opened, and the third solenoid valve 13 on the right pipeline of the three-way pipe of the third level 12 is closed; then the organic solvent can enter the mixing kettle body 2. After the injection is completed, it is processed by the stirring assembly and the adjusting pump and the suction pump 4 stop working. During the processing, the valve on the discharge port of the mixing kettle body 2 is in a closed state;

[0069] When the processing of the organic solvent in the mixing kettle body 2 is completed, the valve on its discharge port is opened immediately, and then the discharging into the discharge pipe 5 can be realized. At this time, the controller controls the first solenoid valve 8 on the lower pipeline of the one-way pipe of the first level 7 to close, and the first solenoid valves 8 on the upper and right pipelines are opened and the suction pump 4 works. At the same time, the second solenoid valves 10 on the lower and left pipelines of the two-way pipe of the second level 9 are opened, and the second solenoid valve 10 on the right pipeline of the two-way pipe of the second level 9 is closed. In addition, the third solenoid valves 13 on the upper and left pipelines of the three-way pipe of the third level 12 are opened, and the third solenoid valve 13 on the right pipeline of the three-way pipe of the third level 12 is closed; then the organic solvent can be transferred and fed into the reaction kettle body 3 for secondary processing. After the injection is completed, it is processed by the stirring assembly and the adjusting pump and the suction pump 4 stop working. And during the processing, the valve on the discharge port of the reaction kettle body 3 is in a closed state;

[0070] When the organic solvent is processed in the reaction kettle body 3, the valve on its discharge port is opened immediately, and discharging into the liquid outlet pipe 6 can be achieved. Then, the organic solvent enters the next process through the liquid outlet pipe 6 for subsequent deep processing;

[0071] During the process of the organic solvent entering the inside of the mixing kettle body 2 and the reaction kettle body 3 through the feeding pipe 14, due to the pressurization of the suction pump 4, splashing of the organic solvent will occur. At this time, due to the existence of the anti-splash cover 17, the kettle covers of the two kettle bodies can be blocked, thereby greatly reducing the probability of the organic solvent adhering to the kettle covers. At the same time, the rotation of the rotating shaft of the stirring assembly will not drive the anti-splash cover 17 to rotate. After the automatic transfer and processing of the organic solvent between the two kettle bodies are completed, clean water is immediately injected into the feeding pipe 1 through the regulating pump;

[0072] Then the controller controls the first solenoid valve 8 on the right pipeline of the first three-way pipe 7 to close, the first solenoid valves 8 on the upper and lower pipelines are opened and the suction pump 4 works. At the same time, the second solenoid valves 10 on all pipelines of the second three-way pipe 9 are opened. In addition, the third solenoid valves 13 on the upper and right pipelines of the third three-way pipe 12 are opened, and the third solenoid valve 13 on the left pipeline of the third three-way pipe 12 is closed. Then water can be injected into the two spray pipes 15 at the same time, and then the effective cleaning of the inside of the two kettle bodies can be achieved through the spray cleaning assembly 16. And during the cleaning process, the anti-splash cover 17 is cleaned. After the cleaning is completed, it can be put into the next round of use. The design that the feeding port is lower than the nozzle can comprehensively clean the organic solvent adhering to the feeding pipe 14;

[0073] Compared with the prior art, in the process of transferring and processing the organic solvent containing photoresist in the mixing kettle and the reaction kettle in this device, no manual intervention is required, the labor intensity is reduced, and there will be no material loss. During this process, the potential safety hazard of manual accidental contact with the organic solvent is also significantly reduced. The production cycle of the organic solvent is strictly and accurately controlled, thereby improving the production efficiency. In addition, through the umbrella-shaped anti-splash cover 17, the phenomenon that the organic solvent splashes on the inner side of the kettle cover and near the feeding port during the transfer and feeding process into the kettle body can be significantly reduced. No disassembly and cleaning are required later, and the automatic cleaning process of the organic solvent adhering to the side wall of the kettle body and the surface of the anti-splash cover 17 can be achieved through the spray cleaning assembly 16.

[0074] In some embodiments, several convex folds are formed by the upward protrusion of the inner side of the anti-splash cover 17. The convex folds are distributed circumferentially about the anti-splash cover 17, and concave folds are formed between adjacent convex folds; this embodiment increases the surface area of the anti-splash cover 17, thereby helping to disperse the organic solvent and prevent it from accumulating in a specific area.

[0075] Further optimization of the above-described embodiment solution, the upper surface of the convex fold has a peak extending radially, and the peak is inclined with the outer part being higher and the inner part being lower; the above-described embodiment solution is not shown in the figure; this embodiment helps to further guide the organic solvent to flow along the inner surface of the splash guard 17, reduce its residence time in the splash guard 17, and further reduce the amount of the organic solvent attached to the splash guard 17.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention.
