Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0023] A highly efficient production device for silicon nitride particles comprises a processing box 1 and a reaction kettle 11, wherein a cutting box 2 is movably installed on the left side of the inner cavity of the processing box 1, a filtering tank 3 is movably installed on the right side of the cutting box 2, a sedimentation tank 4 is movably installed on the right side of the filtering tank 3, a disinfection tank 5 is movably installed on the right side of the sedimentation tank 4, a pH adjustment tank 6 is movably installed on the right side of the disinfection tank 5, a through hole 7 is opened on the right side of the pH adjustment tank 6, and a water outlet pipe 8 is movably installed in the inner cavity of the through hole 7.

[0024] See also Figure 1 , Figure 3 and Figure 4A top plate 9 is movably installed on the top of the cutting box 2, and a water inlet pipe 30 is arranged on the top of the top plate 9. A sol preparation stirring box 10 is arranged on the top of the reactor 11, and a sewage drainage pipe 29 is fixedly installed on the bottom of the reactor 11. One end of the sewage drainage pipe 29 is fixedly connected to the water inlet pipe 30 and is interconnected. An operation panel 12 is movably installed on the left side of the processing box 1, a connecting wire pipe 13 is fixedly installed on the right side of the operation panel 12, and a motor 14 is fixedly installed on the right side of the connecting wire pipe 13. A rotating shaft 15 is movably installed on the back of the motor 14 and passes through the inner cavity of the cutting box 2, and a cutting blade 16 is movably installed on the surface of the rotating shaft 15. A coarse grid 17 is movably installed on the left side of the inner cavity of the filter tank 3, a fine grid 18 is movably installed on the right side of the coarse grid 17, and a membrane grid 19 is movably installed on the right side of the fine grid 18.

[0025] Specifically, by setting the motor 14 inside the cutting box 2 to drive, the rotating shaft 15 can be driven to rotate and drive the cutting blade 16 to operate, so that the solid matter in the sewage can be cut and crushed, which is convenient for filtering the sewage. By setting the water inlet pipe 30, the sewage can be transported to the cutting box 2, and the coarse grid 17 is used to remove larger solid particles. The wastewater is sent to the coarse grid 17 for preliminary filtration, which can prevent these large particles from clogging the fine grid 18 and the membrane grid 19, and can also protect the fine grid 18 and the membrane grid 19. The fine grid 18 can further remove the particles that the coarse grid 17 fails to remove. The smaller particles and suspended matter are removed, and the solid particles, sediments and turbidity in the water are further filtered to improve the working efficiency of the subsequent treatment equipment. The membrane grille 19 can further remove tiny particles, bacteria and organic matter. Its microporous structure can effectively filter tiny particles and dissolved substances in the water. In conjunction with the membrane grille 19, higher standards of water filtration and improved water quality can be achieved. The cleaning and sewage side actions of the coarse grille 17, fine grille 18 and membrane grille 19 can be controlled in linkage to ensure that equipment at each filtration level can work in the best condition, reduce blockage and improve the filtration effect.

[0026] Embodiment 2:

[0027] See also Figure 1 and Figure 2A disinfection water pump 20 is movably installed on the back of the disinfection tank 5, a first conveying line pipe 21 is movably installed on the top of the disinfection water pump 20, a disinfection nozzle 22 is movably installed on the top of the first conveying line pipe 21, an acid-base water pump 23 is movably installed on the back of the pH adjusting tank 6, a second conveying line pipe 24 is movably installed on the top of the acid-base water pump 23, an acid-base nozzle 25 is movably installed on the top of the second conveying line pipe 24, a sliding rod 26 is movably installed on the top of the disinfection tank 5 and the top of the pH adjusting tank 6, a slider 27 is movably installed on the top of the sliding rod 26, a conveying pipe 28 is fixedly installed on the bottom of the sol preparation stirring box 10, and the end of the conveying pipe 28 is fixedly connected to one side of the reactor 11 and communicated with each other.

[0028] Specifically, the provision of the disinfection water pump 20 facilitates the delivery of disinfectant to the disinfection pool 5, which can effectively disinfect the sewage. The provision of the acid-base water pump 23 facilitates the delivery of acid-base reagents to the pH adjustment pool 6, which can effectively adjust the pH value of the sewage.

[0029] Working principle: The stirring box 10 can be used to mix solvents and solutes to prepare sol through sol preparation. The equipment for converting sol into gel state is usually achieved by controlling parameters such as temperature, humidity, pH value, etc. of the sol. Then, the drying mechanism arranged in the reactor 11 is used to gradually remove moisture from the gel to form dry silicon nitride particles. Then, the wastewater will pass through the sewage drainage pipe 29 and then enter the treatment box 1 through the water inlet pipe 30. The motor 14 arranged inside the cutting box 2 is driven, and at the same time, the rotating shaft 15 can be driven to rotate and drive the cutting blade 16 to operate, so that the solid matter in the sewage can be cut and crushed, which is convenient for filtering sewage. The water inlet pipe 30 can be used to transport sewage to the cutting box 2, and the coarse grid 17 is used to remove larger solid particles and send the wastewater into the coarse grid. The grid 17 performs preliminary filtration to prevent these large particles from clogging the fine grid 18 and the membrane grid 19, and also protects the fine grid 18 and the membrane grid 19. The fine grid 18 can further remove smaller particles and suspended matter that the coarse grid 17 fails to remove, and further filter the solid particles, sediments and turbidity in the water, thereby improving the working efficiency of subsequent treatment equipment. The membrane grid 19 can further remove tiny particles, bacteria and organic matter, and its microporous structure can effectively filter tiny particles and dissolved matter in the water. In conjunction with the membrane grid 19, higher standards of filtration and water quality improvement can be achieved. The sewage can be precipitated by setting the sedimentation tank 4, the disinfectant can be transported to the disinfection tank 5 by the disinfection water pump 20, and the acid-base water pump 23 can transport acid-base reagents to the pH adjustment tank 6.

[0030] In summary: the efficient silicon nitride particle production equipment can be linked and controlled through the cleaning and sewage side actions of the coarse grid 17, the fine grid 18 and the membrane grid 19 to ensure that the equipment at each filtering level can work in the best condition, reduce blockage and improve the filtering effect, and perform preliminary treatment on the generated wastewater, including removing large particle impurities, adjusting the pH value, etc. The setting of the acid-base water pump 23 facilitates the delivery of acid-base reagents to the pH adjustment tank, which can effectively adjust the pH value of the sewage, and then utilizes the biodegradation method to degrade the organic waste into harmless substances. The biochemical treatment technology such as the activated sludge method or the biological filter method is adopted to convert the organic waste into stable inorganic substances through the action of microorganisms, ensuring that the wastewater meets the environmental protection requirements after treatment, effectively ensuring the effective treatment of the wastewater generated in the production, and solving the problem that the current sol-gel production equipment has the problem that the wastewater treatment is difficult during use, a large amount of wastewater will be generated, and the wastewater contains chemical agents and impurities, which puts forward higher requirements for wastewater treatment and is difficult to treat.
