Description

Technical Field

[0001] The invention relates to the technical field of diamond surface treatment, in particular to ultrafine diamond particle surface modification chemical treatment reaction equipment. Background Art

[0002] In the field of diamond tool manufacturing, especially when using electroplating to lay diamond particles on the surface of metal wheels, how to make the ultrafine diamond particles firmly wrapped and fixed by the metal coating is a key issue; currently, the surface of the diamond particles is usually modified by making the surface of the diamond particles have an electric charge or adsorbing specific substances to enhance its bonding with the metal coating.

[0003] However, existing chemical treatment equipment has difficulty in accurately controlling reaction conditions during the treatment process, resulting in uneven charge distribution on the surface of diamond particles or inconsistent adsorption of specific substances, which affects the subsequent electroplating effect. Moreover, the stirring method of the equipment cannot fully disperse the ultrafine diamond particles, and agglomeration is prone to occur, resulting in poor surface modification effect. Ultimately, the diamond particles are poorly fixed on the metal wheel surface after electroplating, and are easily detached, which reduces the service life and performance of the diamond tool. Summary of the Invention

[0004] The purpose of the present invention is to provide a surface modification chemical treatment reaction device for ultrafine diamond particles to solve the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ultrafine diamond particle surface modification chemical treatment reaction device, comprising a base, a chemical reaction tank disposed above the base, a temperature control assembly disposed on one side of the chemical reaction tank, an ultrasonic dispersion assembly disposed at the bottom of the chemical reaction tank, a dispersion and stirring assembly disposed at the center of the chemical reaction tank, electrode assemblies disposed on both sides of the dispersion and stirring assembly, and the top and bottom of the chemical reaction tank being connected to a feed assembly and a discharge assembly, respectively; A hollow box and symmetrically arranged brackets are fixed on the base by bolts, a connecting frame is symmetrically welded to the outer wall of the chemical reaction tank, and the connecting frame is fixed to the top of the bracket by bolts, and a vacuum interlayer is provided between the outer wall and the inner wall of the chemical reaction tank; The temperature control assembly includes a temperature sensor, a semicircular coil, a circulation conduit, an oil tank, an oil pump, and a temperature control component. The temperature sensor is fixed to the top of the chemical reaction tank by bolts, and one end of the temperature sensor extends into the interior of the chemical reaction tank. The semicircular coil is welded to the inner wall of the vacuum interlayer. The semicircular coil is connected to one side of the oil tank through the circulation conduit, and the other side of the oil tank is connected to the temperature control component. The temperature control component is connected to the oil pump, and the oil pump is connected to one end of the semicircular coil; The temperature control component is turned on to heat the water in the oil tank, and the oil pump is turned on at the same time to drive the water in the oil tank to circulate in the semicircular coil. The hot oil in the semicircular coil continuously transfers heat to the internal solution through close contact with the inner wall of the chemical reaction tank, which can heat it quickly and evenly. At the same time, the temperature sensor monitors the reaction temperature of the solution in real time and transmits the temperature signal to the temperature control component. The temperature control component automatically adjusts the power of the heating element according to the set temperature value. When the temperature exceeds the preset value, the temperature control component stops heating and accelerates heat dissipation to reduce the temperature of the hot oil in the semicircular coil, cool the reaction temperature, and achieve accurate and rapid control of the reaction temperature, which greatly improves the quality and stability of the surface modification of ultrafine diamond particles.

[0006] The ultrasonic dispersion assembly includes several ultrasonic generators, ultrasonic transducers and ultrasonic receivers. The ultrasonic generators are electrically connected to the ultrasonic transducers through cables. The ultrasonic transducers are fixed to the bottom of the chemical reaction tank by bolts. The top of the ultrasonic transducer is connected to the ultrasonic receiver and is placed inside the chemical reaction tube.

[0007] The ultrasonic generator converts industrial frequency alternating current into a high-frequency electrical signal. By adjusting the frequency and power of the high-frequency electrical signal, the output intensity of the ultrasonic wave can be controlled to adapt to the dispersion requirements of diamond particles of different particle sizes and properties. The ultrasonic transducer converts the high-frequency electrical signal output by the ultrasonic generator into ultrasonic waves and transmits them into the solution. Under the action of ultrasonic vibration, the ultrafine diamond particles in the reaction tank can be fully dispersed to avoid agglomeration. At the same time, it can also promote the reaction between chemical reagents and the surface of diamond particles, improving the surface modification effect. The ultrasonic receiver can monitor the propagation state of ultrasonic waves in the solution, feed back to the ultrasonic generator and adjust the ultrasonic parameters to optimize the dispersion effect.

[0008] Furthermore, one side of the bracket is provided with support plates arranged equidistantly, the ultrasonic generator is arranged on the support plate, an entry hole cover is provided at an eccentric position on the top of the chemical reaction tank, an observation mirror is provided on the entry hole cover, and a frame is welded at the center position of the top of the chemical reaction tank.

[0009] The observation mirror on the manhole cover can directly view the material status and reaction progress in the chemical reaction tank, making it convenient for operators to monitor the reaction process.

[0010] Furthermore, the temperature control component includes a temperature control box, a heating rod, a spiral tube and a fan. The temperature control box is arranged on one side of the oil tank. The temperature control box is electrically connected to the temperature sensor. One side of the temperature control box is connected to the heating rod.

A fan is provided directly above the spiral tube. The fan is electrically connected to the temperature control box. The temperature control box and the oil tank are both arranged in the hollow box.

[0012] The temperature sensor monitors the reaction temperature of the solution in real time and transmits the temperature signal to the temperature control box. The temperature control box automatically adjusts the power of the heating element according to the set temperature value. When the temperature exceeds the preset value, the temperature box stops the heating rod from supplying heat and turns on the fan to accelerate the heat dissipation of the spiral tube, thereby reducing the temperature of the hot oil in the semicircular coil and achieving accurate and rapid control of the reaction temperature.

[0013] Furthermore, the dispersion stirring assembly includes a stirring shaft, a stirring head, a stirring paddle, a motor and a motor connector. The motor is located at the top. The stirring head is a combination structure of a flat-top cone and a cone. The stirring paddle is welded around the circumference of the stirring head and is a propeller-type structure. The stirring head is connected to the bottom end of the stirring shaft and is placed inside the chemical reaction tank.

[0014] Furthermore, the motor connecting part includes a reducer, a coupling and a shaft seal. The top of the reducer is connected to the motor shaft, and the bottom is connected to the stirring shaft through a coupling. The stirring shaft passes through the top of the chemical reaction tank and a shaft seal is nested on the outside of the penetration. The reducer is fixed to the top of the frame by screws.

[0015] When the motor is running, it outputs rotational power. The rotational power is decelerated and torque-increased by adjusting the speed through the reducer, and then transmitted to the stirring shaft through the coupling. The stirring shaft drives the stirring head and stirring paddle installed at its end to rotate, thereby achieving stirring of the material. The shaft seal seals the connection between the stirring shaft and the chemical reaction tank to prevent material leakage or external impurities from entering and ensure that the internal temperature is not affected by the outside world. The propeller-type structure of the stirring paddle can generate strong axial and radial liquid flow when rotating, so that the chemical reagents and diamond particles in the chemical reaction tank are fully mixed.

[0016] Furthermore, the electrode assembly includes a DC power supply, a plate, an electric wire and an insulating rod. The positive and negative poles of the DC power supply are electrically connected to one end of the electric wire, and the other end of the electric wire is electrically connected to the symmetrically arranged plate. An insulating sleeve is provided on the outer side of the plate. The insulating sleeve is nested in the insulating rod and spirally fixed. The insulating rod is welded to the inner wall of the chemical reaction tank, and the DC power supply is arranged on the bracket.

[0017] After the DC power supply is turned on, the current is transmitted to the plates through the wires, generating an electric field between the anode and cathode plates of the plates. Under the action of the electric field, the ions in the electrolyte solution of sodium sulfate undergo an electrochemical reaction on the surface of the diamond particles, making the surface of the diamond particles charged.

[0018] Furthermore, the feed assembly includes a feed funnel, a valve and a feed pipe. The feed pipe is welded to the top of the chemical reaction tank and connected to its interior. The valve is fixed between the feed pipe and the feed funnel by bolts. The discharge assembly includes a valve pipe, a filter and a discharge pipe.

The filter is a sintered metal filter, and one end of the filter is connected to the discharge pipe through a flange.

[0019] After the reaction is completed, all control components are closed, the valve pipeline and the discharge pipe are opened, and the ultrafine diamond particles are filtered through the porous structure of the sintered metal filter to filter out the agglomerated particles and other large reaction impurities, and are collected in a designated container, completing the modification process of making the diamond particle surface charged.

[0020] Furthermore, an adsorbent release assembly is provided between the electrode plates, and the adsorbent release assembly includes an adsorbent carrier, a bearing, a connecting shaft, a straight plate and a linkage part. The two ends of the straight plate are welded to the inner wall of the chemical reaction tank, the bearing is engaged with the middle part of the straight plate and fixed by bolts, the connecting shaft is inserted through the center of the bearing and fastened by bolts, the bottom end of the connecting shaft is connected to the adsorbent carrier by a thread, and the adsorbent carrier is a porous structure.

[0021] Furthermore, the linkage part includes a linkage gear and a shaft gear, the linkage gear is welded on the stirring shaft, the linkage gear is engaged with the shaft gear and meshes with it, and the shaft gear is welded on the connecting shaft.

[0022] When the equipment is required to adsorb specific substances on the surface of diamond particles, Y-aminopropyltriethoxysilane adsorbent (APS) is evenly filled into the porous adsorbent carrier. When the stirring shaft rotates, the linkage gear rotates, thereby driving the shaft gear to rotate on the bearing. The shaft gear drives the adsorbent carrier on the connecting shaft to rotate. Under the action of ultrasonic vibration and carrier rotation, the adsorbent is slowly released from the porous carrier and evenly dispersed in the solution, fully contacting with the diamond particles. The siloxy group at one end of the APS molecule continuously reacts with the hydroxyl group on the surface of the diamond particles, achieving efficient adsorption of APS by the diamond particles. The amino group at the other end of the APS molecule can react with the metal coating in the subsequent electroplating process, thereby improving the interfacial affinity between the diamond particles and the metal coating, reducing the shedding phenomenon during the electroplating process, and enhancing the binding force of the diamond particles. After the reaction is completed, close all components, open the valve pipeline and the discharge pipe for collection.

Example 2

[0043] See also Figure 12 The difference between the second embodiment and the first embodiment is that an adsorbent release assembly 9 is provided between the electrode plates 62. The adsorbent release assembly 9 includes an adsorbent carrier 91, a bearing 92, a connecting shaft 93, a straight plate 94, and a linkage. The two ends of the straight plate 94 are welded to the inner wall of the chemical reaction tank 2. The bearing 92 is engaged with the middle of the straight plate 94 and fixed by bolts.

[0045] When the device is required to adsorb a specific substance on the surface of diamond particles, a porous adsorbent carrier 91 is uniformly filled with Y-aminopropyltriethoxysilane adsorbent (APS).

After the reaction is completed, close all components, open the valve pipeline 81 and the discharge pipe 83 for collection.

[0046] The specific usage and function of this embodiment are as follows: When using the device to charge the surface of diamond particles, first, fix the chemical reaction tank 2 and connect the temperature control component 3, ultrasonic dispersion component 4, dispersion and stirring component 5, electrode assembly 6 and feeding and discharging system. Then, set the appropriate reaction temperature through the temperature control box 36. Then, add an appropriate amount of ultrafine diamond particles through the feeding funnel 71 and feed it into the chemical reaction tank 2 through the feeding pipe 73. Then, add a deionized water solution containing sodium sulfate at an appropriate concentration as an electrolyte solution. The solution volume covers two-thirds of the height of the chemical reaction tank 2. Then, close the valve 72 to seal the chemical reaction tank 2. Then, the temperature control box 36 is turned on, and the water in the oil tank 34 is heated by the heating rod 37. At the same time, the oil pump 35 is turned on to drive the water in the oil tank 34 to circulate in the semicircular coil 32. The hot oil in the semicircular coil 32 continuously transfers heat to the internal solution through close contact with the inner wall of the chemical reaction tank 2, and can heat it quickly and evenly. At the same time, the temperature sensor 31 monitors the reaction temperature of the solution in real time and transmits the temperature signal to the temperature control box 36. The temperature control box 36 automatically adjusts the power of the heating element according to the set temperature value. When the temperature exceeds the preset value, the temperature box 36 stops the heating of the heating rod 37 and turns on the fan 39 to accelerate the heat dissipation of the spiral tube 38, so that the temperature of the hot oil in the semicircular coil 32 is reduced, the reaction temperature is cooled, and the reaction temperature is accurately and quickly controlled, thereby greatly improving the quality and stability of the surface modification of ultrafine diamond particles. When the reaction temperature of the solution reaches a stable preset temperature, the motor 54 is started. When the motor 54 is running, it outputs rotational power. The rotational power is regulated by the speed reducer 55 to reduce speed and increase torque, and then transmitted to the stirring shaft 51 through the coupling 56. The stirring shaft 51 drives the stirring head 52 and the stirring paddle 53 installed at the end thereof to rotate, thereby achieving stirring of the material. The shaft seal 57 seals the connection between the stirring shaft 51 and the chemical reaction tank 2 to prevent material leakage or external impurities from entering and to ensure that the internal temperature is not affected by the outside world. The propeller-type structure of the stirring paddle 53 can generate strong axial and radial liquid flow during rotation, so that the chemical reagents and diamond particles in the chemical reaction tank 2 are fully mixed. During the reaction, the ultrasonic generator 41 and the DC power supply 61 are turned on simultaneously. The ultrasonic generator 41 converts industrial frequency alternating current into a high-frequency electrical signal. By adjusting the frequency and power of the high-frequency electrical signal, the output intensity of the ultrasonic wave can be controlled to adapt to the dispersion requirements of diamond particles of different particle sizes and properties. The ultrasonic transducer 42 converts the high-frequency electrical signal output by the ultrasonic generator 41 into ultrasonic waves and transmits them into the solution. Under the action of ultrasonic vibration, the ultrafine diamond particles in the reaction tank 2 can be fully dispersed to avoid agglomeration. At the same time, it can also promote the reaction between the chemical reagent and the surface of the diamond particles, improving the surface modification effect. The ultrasonic receiver 43 can monitor the propagation state of the ultrasonic wave in the solution, feedback it to the ultrasonic generator 41, and adjust the ultrasonic parameters to optimize the dispersion effect. After the DC power supply 61 is turned on, current is transmitted to the electrode plate 62 through the wire 63, generating an electric field between the anode and cathode plates of the electrode plate 62. Under the action of the electric field, the ions in the sodium sulfate electrolyte solution undergo an electrochemical reaction on the surface of the diamond particles, causing the diamond particles to have a surface charge. After the reaction is completed, the control components are closed, the valve pipe 81 and the discharge pipe 83 are opened, and the ultrafine diamond particles are filtered through the porous structure of the sintered metal filter 82 to filter out agglomerated particles and other large reaction impurities. The particles are then collected in a designated container, completing the modification process of making the diamond particles have a surface charge. When it is necessary to use the device to adsorb a specific substance on the surface of the diamond particles, an adsorbent carrier 91, a bearing 92, a connecting shaft 93, a straight plate 94, a linkage gear 95, and a shaft gear 96 are added to the chemical reaction tank 2. First, the porous structure of the adsorbent carrier 91 is evenly filled with Y-aminopropyltriethoxysilane adsorbent (APS). The adsorbent carrier 91 is installed in the reaction tank. Then, ultrafine diamond particles and anhydrous ethanol solution are added to the chemical reaction tank 2. The valve 72 is closed, and the temperature control component 3, the ultrasonic dispersion component 4, and the dispersion and stirring component 5 are started. When the stirring shaft 51 rotates, it drives the linkage gear 95 to rotate, thereby driving the shaft gear 96 to rotate on the bearing 92. The shaft gear 96 drives the adsorbent carrier 91 on the connecting shaft 93 to rotate. Under the action of ultrasonic vibration and carrier rotation, the adsorbent is slowly released from the porous carrier and evenly dispersed in the solution, fully contacting the diamond particles. The siloxy group at one end of the APS molecule continuously reacts with the hydroxyl group on the surface of the diamond particles, achieving efficient adsorption of APS by the diamond particles. The amino group at the other end of the APS molecule can react with the metal coating in the subsequent electroplating process, thereby improving the interfacial affinity between the diamond particles and the metal coating, reducing the shedding phenomenon during the electroplating process, and enhancing the binding force of the diamond particles. After the reaction is completed, close all components, open the valve pipeline 81 and the discharge pipe 83 for collection.
