Description

Technical Field

[0001] The utility model belongs to the technical field of 3D resin printing liquid recovery, and particularly relates to a 3D printing resin liquid recovery machine. Background Technique

[0002] After a 3D resin model is printed, the model needs to be cleaned to remove impurities and residues on the surface of the model, so that the surface of the model is smoother and clearer, thereby improving the overall quality of the model. After the model is cleaned, printing waste liquid will be generated, so the printing waste liquid needs to be treated.

[0003] Currently, when treating printing waste liquid, it is necessary to separate solid particles or dissolved substances in the waste liquid by filtration and stirring methods, and transfer the filtered waste liquid to a container with environmental protection liquid for chemical reaction, and finally transfer it to a heating container for heating and solidification to form solid waste. However, during the above operations, when treating printing waste liquid, the printing waste liquid generally still contains a small amount of printing liquid, and the printing liquid often has a high cost. Therefore, when treating printing waste liquid, if the printing liquid in the waste liquid is not recovered, it will cause a certain amount of waste, thus increasing the material cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a 3D printing resin liquid recovery machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A 3D printing resin liquid recovery machine, comprising:

[0006] A machine body, a printing liquid recovery area is arranged inside the machine body, a recovery tank, a dewatering tank, and a collection box are arranged inside the printing liquid recovery area. The recovery tank is arranged inside the machine body and the dewatering tank is arranged inside the recovery tank. The inner wall of the dewatering tank is provided with openings. The bottom of the recovery tank is provided with a recovery liquid discharge hole and a collection box. After centrifuging the model residual liquid in the dewatering tank, the separated printing recovery liquid can be centrifuged into the recovery tank through the openings on the inner wall of the dewatering tank, and discharged into the collection box through the recovery liquid discharge hole at the bottom of the recovery tank for recycling.

[0007] Preferably, a positioning cover is covered on the top of the recovery tank. A driving wheel is rotatably connected to the surface of the positioning cover through a rotating shaft, and the other end of the rotating shaft rotatably penetrates through the positioning cover and is connected to a transmission wheel inside the dewatering tank.

[0008] Preferably, a positioning column is arranged at the center of the bottom inside the recovery tank, and a positioning groove is arranged at the center of the bottom of the dewatering tank. After the dewatering tank is placed inside the recovery tank, the positioning column is inserted into the positioning groove in a matching manner.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: By placing the 3D resin printing model in the printing liquid recovery area to remove the residual printing liquid on the model, and putting the model into the liquid removal tank. Since the output shaft of the externally connected motor is connected to the driving wheel, the motor can drive the driving wheel to rotate. The driving wheel drives the driven wheel to rotate through the rotating shaft. The residual liquid on the model in the liquid removal tank is centrifuged by the driven wheel. The separated printing recovery liquid is centrifuged into the recovery tank through the opening on the inner wall of the liquid removal tank, and is discharged into the collection box through the recovery liquid discharge hole at the bottom of the recovery tank, so as to recycle the recovery liquid.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] The present utility model provides a 3D resin printing three-in-one processing machine as Figures 1-4 shown, including:

[0017] The body 1 is provided with a processing box 2 on one side. An opening 3 is provided on the top surface of the body 1, and an ultrasonic stirring and cleaning area 4 is provided at the bottom of the opening 3. An ultrasonic cleaner with a magnet stirring function is installed in the ultrasonic stirring and cleaning area 4. By using ultrasonic technology to stir and clean the waste liquid, it helps to disperse the solid particles or dissolved substances in the waste liquid for subsequent treatment. The ultrasonic stirring and cleaning area 4 is designed with a water collecting tank at the bottom for facilitating the collection of waste liquid for treatment. Inside the top of the processing box 2, there is a printing liquid recovery area 5 for recovering the residual printing liquid of the model. Inside the body 1 and at the bottom of the printing liquid recovery area 5, there is a waste liquid collection area and an environmental protection liquid placement area 6 for treating the waste liquid and generating an organic chemical reaction. By integrating the ultrasonic stirring and cleaning area 4, the printing liquid recovery area 5, the waste liquid collection area and the environmental protection liquid placement area 6, the body 1 can clean the resin printing model, recover the printing liquid and treat the waste liquid.

[0018] A gas filtration area 8 is provided between the printing liquid recovery area 5 and the waste liquid collection area and the environmental protection liquid placement area 6, and an exhaust port 9 is provided on one side of the gas filtration area 8.

[0019] A fixing bracket 10 for installing and fixing the motor is provided in the ultrasonic stirring and cleaning area 4. The motor in the ultrasonic stirring and cleaning area 4 can be supported and fixed by the fixing bracket 10 to solve the problems of shaking and water leakage and protect the motor.

[0020] The ultrasonic stirring and cleaning area 4 and the waste liquid collection area and the environmental protection liquid placement area 6 are connected by pipelines. A recovery box for collecting the printing liquid is provided in the printing liquid recovery area 5. The waste liquid is centrifuged into the recovery box through the openings on the inner wall of the liquid separation tank in the printing liquid recovery area 5 and discharged from the recovery liquid discharge hole of the recovery box, so that the recovery liquid can be recycled to reduce costs.

[0021] Inside the body 1 and at the bottom of the ultrasonic stirring and cleaning area 4, there is a chemical reaction area 11, and a volatile substance detector 12 is provided in the chemical reaction area 11. A solid waste generation area 7 is provided at the bottom of the chemical reaction area 11. The volatile substance detector 12 monitors the organic volatile substances to prevent safety monitoring alarms such as poisoning of personnel or fires.

[0022] The waste liquid collection area and the environmental protection liquid placement area 6 and the solid waste generation area 7 are connected by pipelines.

[0023] This 3D resin printing three-in-one processing machine recovers the residual printing liquid of the model by placing the 3D resin printing model in the printing liquid recovery area 5. The model enters the ultrasonic stirring and cleaning area 4 for cleaning. The wastewater generated after cleaning is pumped into the pipeline connected to the waste liquid collection area and the environmental protection liquid placement area 6 and pumped into the waste liquid collection area and the environmental protection liquid placement area 6. The waste liquid in the waste liquid collection area and the environmental protection liquid placement area 6 and a certain proportion of environmental protection liquid (0.01 - 1000 ml) are pumped into the mixer for mixing. The mixing of the waste liquid and the environmental protection liquid in the waste liquid collection area and the environmental protection liquid placement area 6 will produce an organic chemical reaction, eliminate and reduce the generation of organic volatiles and harmful substances (the reaction time is 0.01 - 1000 seconds). The gas is filtered by the filter in the gas filtration area 8, and the filtered gas is discharged from the exhaust port 9 out of the machine body 1. The waste liquid after the reaction in the waste liquid collection area and the environmental protection liquid placement area 6 can be pumped into the solid waste generation area 7 through the pipeline, and a photochemical catalytic reaction is carried out through the chemical reaction area 11 (specific light source 10 - 1000 nm, triggering catalytic exothermic reaction and photochemical reaction). Finally, an exothermic reaction occurs in the solid waste generation area 7 to form solid waste, completing the treatment of the waste liquid. By integrating the functions of resin printing liquid recovery, model cleaning and waste liquid treatment into one machine, manual operation and treatment time can be reduced, costs can be lowered, and treatment efficiency can be improved.

[0024] A printing liquid recovery area is provided inside the machine body. A recovery tank 13 and a liquid draining tank 14 are arranged inside the printing liquid recovery area. The recovery tank 13 is arranged inside the machine body and the liquid draining tank 14 is arranged inside the recovery tank 13. Openings 21 are provided on the inner wall of the liquid draining tank 14. A recovery liquid discharge hole 20 is provided at the bottom of the recovery tank 13. After centrifuging the waste liquid in the liquid draining tank 14, the separated printing recovery liquid can be centrifuged into the recovery tank 13 through the openings 21 on the inner wall of the liquid draining tank 14 and discharged into the collection box 22 through the recovery liquid discharge hole 20 at the bottom of the recovery tank 13 for recycling.

[0025] A positioning cover 17 is covered on the top of the recovery tank 13. A driving wheel 18 is rotatably connected to the surface of the positioning cover 17 through a rotating shaft, and the other end of the rotating shaft rotatably penetrates through the positioning cover 17 and is connected to a transmission wheel 19 inside the liquid draining tank 14. The output shaft of the motor is connected to the driving wheel 18. Therefore, the motor can drive the driving wheel 18 to rotate. The driving wheel 18 drives the transmission wheel 19 to rotate through the rotating shaft, and the waste liquid in the liquid draining tank 14 is centrifuged by the transmission wheel 19.

[0026] A positioning column 15 is provided at the center of the bottom inside the recovery tank 13, and a positioning groove 16 is provided at the center of the bottom of the liquid draining tank 14. After the liquid draining tank 14 is placed inside the recovery tank 13, the positioning column 15 is inserted into and cooperates with the positioning groove 16. By inserting the positioning column 15 into the positioning groove 16, the connection stability between the recovery tank 13 and the liquid draining tank 14 can be enhanced, avoiding shaking during the operation of the motor.

[0027] For this 3D printing resin liquid recycling machine, the 3D resin printing model is placed in the printing liquid recycling area to rinse the residual printing liquid on the model, and the waste liquid is discharged into the liquid separation tank 14. Since the output shaft of the externally connected motor is connected to the driving wheel 18, the motor can drive the driving wheel 18 to rotate. The driving wheel 18 drives the transmission wheel 19 to rotate through the rotating shaft. The waste liquid in the liquid separation tank 14 is centrifuged by the transmission wheel 19. The separated printing recycled liquid is centrifuged into the recycling tank 13 through the opening 21 on the inner wall of the liquid separation tank 14, and is discharged into the collection box 22 through the recycling liquid discharge hole 20 at the bottom of the recycling tank 13 for recycling the recycled liquid. Moreover, the bottom of the recycling tank 13 and the liquid separation tank 14 are supported and fixed by inserting the positioning posts 15 into the positioning grooves 16 to solve the problems of shaking and water leakage and protect the motor.

[0028] Moreover, the 3D resin printing model after recycling the printing liquid can be placed back into the ultrasonic stirring cleaning area in the machine body for cleaning. The waste water generated after cleaning is pumped into the waste liquid collection area through a pipeline, and the waste liquid and the environmental protection liquid are pumped into a mixer at a certain ratio to mix and produce an organic chemical reaction to eliminate and reduce the generation of organic volatile compounds and harmful substances. Then, it is filtered by a high-efficiency filter in the gas filtration area, and the filtered gas is discharged from the machine body through the exhaust port. The waste liquid generated after the reaction between the waste liquid collection area and the environmental protection liquid placement area can be pumped into the solid waste generation area through a pipeline, and a photochemical catalytic reaction is carried out in the chemical reaction area, and finally an exothermic reaction is carried out in the solid waste generation area to form solid waste. Thus, after recycling the printing liquid in the printing liquid recycling area, the machine body can also clean the model and treat the waste liquid. The three functions are integrated into one to reduce manual operation and processing time and improve processing efficiency.
