Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, and in particular to an ultrasonic stirring device for producing diamond polishing liquid. Background Art

[0002] Diamond grinding fluid is a liquid with grinding effect formed by dispersing diamond into a liquid medium by adding dispersants. Diamond grinding fluid, especially nano-diamond grinding fluid, is mostly made by ultrasonic dissolution to reduce the interaction between the micropowder and the solvent molecules in the solvent, thereby increasing the distance between molecules and making the micropowder easier to dissolve. However, the ultrasonic dissolution method is easily restricted by various conditions when used, such as the fluctuation of ultrasonic energy: too high energy may lead to decomposition or denaturation of the position, and high operation precision is required.

[0003] In order to reduce the scrap rate, companies will choose ultrasonic dispersion for processing and production when ultrasonic dissolution is not necessary. Ultrasonic dispersion is based on ultrasonic cavitation and is mainly used to reduce small particles in liquids to improve the uniformity and stability of liquids. It is an effective method to reduce soft and hard particles. However, when the granular material is just injected into the liquid, especially in large-scale industrial production and large pouring volume, it is easy to agglomerate, which affects the diffusion of particles.

[0004] To this end, the present application provides an ultrasonic stirring device for diamond polishing liquid production to reduce the impact of particle agglomeration on the ultrasonic dispersion efficiency of the polishing liquid.

[0005] Application Contents

[0006] The purpose of the present application is to solve the problems existing in the prior art and to propose an ultrasonic stirring device for diamond polishing liquid production.

[0007] In order to achieve the above purpose, this application adopts the following technical solutions:

[0008] An ultrasonic stirring device for producing diamond grinding liquid comprises a stirring tank and an end cover, wherein the end cover is driven by a lifting device to move vertically; a plurality of bucket tubes which can be opened and closed are arranged on the end cover, a mounting tube is rotatably mounted at the center of the inner wall of the end cover, and an ultrasonic generator is detachably mounted at the bottom end of the mounting tube; a circulation tube is connected to the upper end of the mounting tube, and the end of the circulation tube is inserted into the end cover from the outside of the end cover; a plurality of hollow stirring rods are mounted on the side wall of the mounting tube, the stirring rods are arranged obliquely, the inner cavities of the stirring rods are connected to the inner cavities of the mounting tube, and air holes are arranged at the bottom ends of the stirring rods.

[0009] Preferably, the stirring rod is spirally arranged.

[0010] Preferably, the distances between two adjacent stirring rods and the mounting tube are different.

[0011] Preferably, an auxiliary pipe is provided at the end of the circulation pipe at the connection with the installation pipe.

[0012] Preferably, a suspension is provided on the inner bottom wall of the mixing tank, and a mounting rod is rotatably mounted on the bottom end of the mounting tube, and the mounting rod is fixedly connected to the suspension.

[0013] Preferably, there are multiple circulating pipe annular arrays, one end of the multiple circulating pipes is inserted into the end cover, and the other ends are connected to each other and then connected to the installation pipe, and the auxiliary pipe is arranged at the common connection of the multiple circulating pipes.

[0014] Preferably, the lifting device is any one of a hydraulic rod, an electric telescopic rod, and a screw drive assembly.

[0015] Compared with the prior art, the present application provides an ultrasonic stirring device for producing diamond polishing liquid, which has the following beneficial effects:

[0016] The ultrasonic generator generates high-frequency ultrasonic waves. The ultrasonic cavitation in the liquid causes a high-speed liquid jet of up to 600 mph, which squeezes the liquid between the particles at high pressure and separates them from each other. Smaller particles will accelerate and collide at high speed with the liquid jet, thereby promoting particle dispersion and fusion. The jet agitation will cause the liquid to churn and even generate bubbles. The high-frequency jet agitates the bubbles, and the bubbles rise. Due to the closure of the end cover, the air pressure in the mixing tank increases, and the gas enters the installation pipe from the circulation pipe, and then is injected into the mixing tank, and finally ejected from the pores. As the air pressure gradually increases, the air pressure of the gas ejected from the pores gradually increases, thereby forming a thrust, causing the stirring rod to deflect and form a stirring effect. As the stirring rod stirs, the stacked granular materials will separate faster, which can improve the mixing efficiency; and it is also easy to break up the agglomerated particles to avoid the particles agglomerating and affecting the mixing effect and mixing efficiency.

[0017] Other advantages, objectives and features of the present application will be described in the following description to some extent; and will be apparent to those skilled in the art based on the following examination and study to some extent; or, may be taught from the practice of the present application.

[0026] Principle details of this embodiment:

[0027] An ultrasonic stirring device for producing diamond polishing liquid comprises a stirring tank 1 and an end cover 4. The lower end of the stirring tank 1 is arc-shaped, and a discharge pipe is provided on the arc-shaped bottom wall. An electric valve is provided in the discharge pipe to control the opening and closing of the discharge pipe to control the discharge. A plurality of brackets 3 are arranged in an annular array on the side wall of the stirring tank 1, and a support plate is provided on the upper end of each bracket 3, and the support plate is supported at the connection between the arc-shaped bottom end of the stirring tank 1 and the side wall. The support plate is detachably connected to the stirring tank 1 via fasteners, which is convenient for disassembly and replacement.

[0028] The end cover 4 is driven by the lifting device 2 to move vertically; the end cover 4 is provided with a plurality of bucket tubes 8 that can be opened and closed, and the plurality of bucket tubes 8 are used to put materials and insert cutting detection instruments respectively. A mounting tube 5 is rotatably installed at the center of the inner wall of the end cover 4, and an ultrasonic generator 6, a transducer and other electronic components for generating and emitting ultrasonic waves are detachably installed at the bottom of the mounting tube 5. The ultrasonic generator is also called an ultrasonic power supply or an ultrasonic source, which can convert electrical energy into a high-frequency alternating current signal that matches the ultrasonic transducer. A circulation tube 9 is connected to the upper end of the mounting tube 5: the circulation tube 9 is in an inverted U shape, one end of the circulation tube 9 is inserted from the center of the end cover 4 and connected to the mounting tube 5, and the other end of the circulation tube 9 is inserted from the outside of the end cover 4 into the end cover 4. A plurality of hollow tubes are installed on the side wall of the mounting tube 5, and a hollow stirring rod 7 is connected to the end of the hollow tube. The stirring rod 7 is arranged obliquely, and the inner cavity of the stirring rod 7 is connected to the inner cavity of the mounting tube 5, and an air hole is provided at the bottom of the stirring rod 7.

[0029] When in use, pour the material and close the end cover 4. Start the ultrasonic generator 6 to generate high-frequency ultrasonic waves. The ultrasonic cavitation in the liquid causes a high-speed liquid jet of up to 600 mph, which squeezes the liquid between the particles at high pressure and separates them from each other. The smaller particles will accelerate and collide at high speed with the liquid spray, thereby promoting the dispersion of the particles and promoting fusion. The jet is agitated to produce a large number of fine bubbles. The high-frequency jet agitates the bubbles, and the bubbles rise. Since the end cover 4 is closed, the air pressure in the stirring tank 1 increases, and the gas enters the installation tube 5 from the circulation pipe 9, and then is injected into the stirring tank 1, and finally ejected from the pores. As the air pressure gradually increases, the air pressure of the gas ejected from the pores gradually increases, thereby forming a thrust, causing the stirring rod 7 to deflect and form a stirring effect. With the stirring of the stirring rod 7, the stacked granular materials will be separated faster, which can improve the mixing efficiency; and it is also easy to break up the agglomerated particles to avoid the particles agglomerating and affecting the mixing effect and mixing efficiency.

A bucket tube 8 is used, and a regulating valve is inserted into the port of the bucket tube 8. One of the bucket tubes 8 is provided with an air pressure detector inserted into the stirring tank 1, such as an air pressure sensor, for detecting the air pressure in the stirring tank 1. The air pressure detector, the ultrasonic generator 6, and the air pump are electrically connected to adjust and balance the air pressure in the stirring tank 1.

[0031] Preferably, the bracket 3 and the lifting device 2 are fixed together on the same base, and a plurality of universal wheels with self-locking function are evenly distributed on the bottom end of the base to facilitate transfer.

[0032] Preferably, an inclined plate is provided at the bottom end of the stirring rod 7, and the fine bubbles float up and rest against the inclined plate, and the inclined plate is stressed to assist the stirring rod 7 in deflection.

[0033] In a further embodiment of the present invention, the stirring rod 7 is spirally arranged. Compared with a straight inclined rod body, a spiral rod body is more conducive to stirring.

[0034] In a further embodiment of this solution, refer to the attached Figure 4 and attached Figure 5 As shown, the distances between two adjacent stirring rods 7 and the mounting tube 5 are different, so as to stir particles in different ranges, increase the stirring range, and further improve the stirring effect and efficiency.

[0035] In a further embodiment of the present invention, the end of the circulation pipe 9 at the connection with the mounting pipe 5 is provided with an auxiliary pipe 10, and a seal is detachably installed at the port of the auxiliary pipe 10. Since the stirring rod 7 is immersed in the liquid, the inner wall of the stirring rod 7 is inevitably adhered to the liquid. After the stirring and mixing is completed, the auxiliary pipe 10 is opened and clean water is injected for flushing and cleaning. The auxiliary pipe 10 is closed at other times to avoid air leakage.

[0036] Preferably, a one-way valve is provided in each of the circulation pipes 9 near the auxiliary pipe 10 , so that the injected clean water can be injected into the stirring rod 7 along the installation pipe 5 .

It is used to limit the ultrasonic generator 6, so that the stirring rod 7 and the mounting tube 5 rotate, and the ultrasonic generator 6 remains stable to avoid affecting the line connection due to rotation.

[0038] In a further embodiment of the present invention, there are multiple circulation pipes 9 in an annular array, one end of the multiple circulation pipes 9 is inserted into the end cover 4, and one end is connected to each other and then connected to the installation pipe 5, and the auxiliary pipe 10 is arranged at the common connection of the multiple circulation pipes 9.
