Description

Technical Field

[0001] The invention relates to the technical field of grinding liquid supply barrels, and in particular to a grinding liquid dynamic supply barrel with a constant temperature control function. Background Art

[0002] Temperature control is a crucial factor influencing the performance and processing quality of abrasive slurries during their use. Abrasive slurries are typically highly viscous, oil-based liquids containing a certain amount of abrasive particles. Their viscosity and particle distribution can vary significantly with temperature. To maintain slurry stability and processing efficiency, direct heating of the slurry supply barrel is often employed to maintain a suitable temperature.

[0003] However, the existing grinding liquid supply barrel has many shortcomings in temperature control. For example, the Chinese utility model patent with announcement number CN210613451U and patent name is a constant temperature barrel for grinding machine abrasives. It specifically discloses a constant temperature barrel and an infusion tube connected to the constant temperature barrel. The constant temperature barrel includes a barrel body and an agitator arranged in the barrel body. The top of the barrel body is provided with a barrel cover, and the agitator is connected to the barrel cover. The agitator is connected to a heater. By arranging a stirring rod with a heating function in the abrasive barrel, the stirring liquid is stirred and heated, so that the concentration and temperature of the stirring liquid can make the stirring liquid uniform during the transportation process, reducing the crystallization of the stirring liquid when it is discharged. The thermal insulation coat on the outside of the delivery tube can perform constant temperature protection on the infusion tube, reducing the temperature drop and crystallization of the stirring liquid after leaving the constant temperature barrel, clogging the infusion tube, and ensuring smooth infusion.

[0004] In the above scheme, a heater is set on the side wall or bottom of the barrel, and heat is transferred to the grinding liquid from a single point, resulting in the temperature of the area close to the heat source being significantly higher than the core area, resulting in uneven heat transfer, local overheating or cold areas, and uneven temperature distribution. Secondly, due to the poor thermal conductivity of high-viscosity liquids, the heat transfer efficiency is low, the heating process takes a long time, and the temperature regulation lags, making it difficult to respond quickly to temperature changes. Direct heating is also prone to energy waste, especially in situations where high temperature control accuracy is required. The heating system needs to run continuously, increasing energy consumption.

[0005] Therefore, a grinding liquid dynamic supply liquid barrel with a constant temperature control function is proposed to solve the above-mentioned problems. Summary of the Invention

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Example:

[0040] Please refer to the attached Figure 1-8 This solution proposes a grinding liquid dynamic supply barrel with constant temperature control function, by setting horizontally distributed stirring rollers 10 inside the barrel body 2 and combining the intermittent operation of two sets of elastic membranes 3.

[0041] Mechanical agitation and the periodic pressure waves generated by the elastic membrane 3 promote the dynamic flow of the polishing fluid and uniform heat transfer, effectively improving temperature control. This solution not only enhances the uniformity and precision of temperature control, but also strengthens the ability to suppress particle settling, significantly improving the stability and processing performance of the polishing fluid.

[0042] Compared with the traditional direct heating method, this solution has the advantages of low energy consumption, high efficiency and strong adaptability. It is a more efficient, intelligent and environmentally friendly temperature control solution.

[0043] Specifically, the barrel body 2 is installed on the mounting platform 1, and the mounting platform 1 provides a solid mounting foundation for the barrel body 2, so that when the device is working, the stirring roller 10 stirs the grinding liquid in the barrel body 2, and at the same time, the pressure wave generating mechanism emits pressure waves into the barrel body 2, which can effectively suppress the resonance effect caused by the superposition of the mechanical vibration of the stirring roller 10 and the high-frequency oscillation of the pressure wave, thereby ensuring the stability of the grinding liquid flow field and the energy transfer efficiency of the pressure wave, avoiding the process parameter drift caused by the displacement of the barrel body 2, and improving the system reliability.

[0044] Both sides of the barrel 2 are set to be open, and two sets of pressure wave generating mechanisms are installed on each side. When the device needs to control the temperature of the grinding liquid filled in the barrel 2, the pressure wave generating mechanism is controlled to generate pressure waves and emit them into the grinding liquid inside the barrel 2.

[0045] The pressure wave propagates throughout the slurry, causing it to compress and expand, which in turn sets the particles in the slurry in motion. The slurry particles are accelerated, decelerated, or change direction under the action of the pressure wave, thus reducing particle settling.

[0046] At the same time, the movement of the particles caused by the pressure wave increases friction between the particles and between the particles and the liquid molecules. This friction generates heat, causing the liquid temperature to rise. The periodic movement of the pressure wave generator converts mechanical energy into kinetic energy and internal energy of the polishing fluid. Some of this energy is converted into heat, further raising the temperature of the polishing fluid and achieving thermal insulation control. Furthermore, when the pressure wave generator operates at a high frequency and for a long duration, heat gradually accumulates in the polishing fluid, further controlling the temperature rise of the polishing fluid.

[0047] More specifically, the pressure wave generating mechanism includes an elastic membrane 3 connected to the side opening of the barrel 2. This membrane is used to seal the side opening of the barrel 2 to prevent leakage of the polishing fluid. When the elastic membrane 3 is pulled outward and deformed by an external force, the volume of the space within the barrel 2 increases, and the polishing fluid is drawn into the deformed area of ​​the elastic membrane 3, creating a localized negative pressure.

[0048] When the elastic membrane 3 rebounds, the volume inside the barrel 2 decreases, forcing the liquid out of the deformed area, forming a positive pressure. The reciprocating motion of the elastic membrane 3 causes the volume of the grinding liquid inside the barrel 2 to change periodically, thereby generating periodic pressure changes in the grinding liquid.

[0049] This pressure change propagates in the grinding fluid in the form of waves, forming a pressure wave.

[0050] It should be noted that a pressure wave generating drive mechanism is installed below the mounting platform 1 , which is used to control the deformation of the elastic membrane 3 on the side of the barrel body 2 , thereby emitting pressure waves into the grinding liquid in the barrel body 2 .

[0051] The pressure wave generating drive mechanism includes a bottom mounting frame 11 mounted on the mounting platform 1 , a driving motor is mounted on the bottom mounting frame 11 , and an eccentric wheel 12 is connected to the output shaft of the driving motor.

[0052] By driving the eccentric wheel 12 to rotate through the driving motor, the intermittent deformation of the two groups of elastic membranes 3 is controlled by the rotation of the eccentric wheel 12, so that the pressure wave generating drive mechanism can simultaneously drive the two groups of pressure wave generating mechanisms to operate, and the operating cycles of the two groups of pressure wave generating mechanisms are different, thereby causing the two groups of elastic membranes 3 to generate different periods of deformation and emission of pressure waves, thereby generating asynchronous pressure waves in the grinding liquid, forming a complex flow pattern.

[0053] This mode may be more effective in reducing particle sedimentation in the grinding fluid, because the superposition of waves in different directions will promote the random movement and resuspension of particles, avoid the flow of grinding fluid driven by a single-direction pressure wave, reduce local shear stress concentration, and improve the stability of the equipment.

[0054] At the same time, due to the asynchronous pressure waves, energy transfer is more dispersed, local friction heat accumulation is less, and the rate of temperature rise is easier to control.

[0055] Furthermore, the pressure wave generating drive mechanism further includes a fixed rod 13 connected to the mounting platform 1 , and a slider 14 is slidably mounted on the surface of the fixed rod 13 , and the slider 14 is located within the rotation track of the eccentric wheel 12 .

[0056] The slider 14 is configured to be trapezoidal with its inclined surface facing the rotation direction of the eccentric wheel 12 . When the eccentric wheel 12 rotates, it abuts against the inclined surface of the slider 14 and pushes the slider 14 to slide on the surface of the fixing rod 13 .

[0057] The surface of the slider 14 is connected to a connecting rod 16, and an L-shaped slide 17 is provided between the connecting rod 16 and the electromagnet 19. The slide 17 can move linearly, and a mounting rod 18 is connected to the upper end thereof. The mounting rod 18 and the slide 14 are connected to the electromagnet 19 in an L-shape as a whole.

[0058] The connecting rod 16 is connected to the slide 17 slidably mounted on the surface of the mounting platform 1. When the eccentric wheel 12 drives the slider 14 to slide on the surface of the fixed rod 13, the slide 17 can be controlled to slide linearly synchronously; and the inclined surface of the slider 14 is on the side facing away from the slide 17.

[0059] The elastic membrane 3 is connected to a sealing body 4 at its center, and a metal block 20 is attached to its outer surface. When the mounting rod 18 is energized and contacts the metal block 20, it adheres to the metal block 20 and becomes fixed to the body. The sealing body 4 is connected to a spring 15 on the side facing the slide 17, which is sleeved onto the surface of the fixing rod 13.

[0060] When the eccentric wheel 12 contacts the inclined surface of the slider 14 and pushes the slider 14 to slide on the surface of the fixed rod 13, it squeezes the spring 15 to achieve elastic force accumulation.

[0061] Furthermore, when the slider 14 is not subjected to the thrust of the eccentric wheel 12, the slider 14 moves away from the side of the slide 17 under the elastic force of the spring 15, thereby causing the mounting rod 18 to push the electromagnet 19 to slide toward the side of the metal block 20, so that the electromagnet 19 will absorb the metal block 20 and fix them together after being energized.

[0062] At this time, when the pressure wave generating mechanism needs to emit pressure waves into the grinding liquid in the barrel body 2, it first drives the eccentric wheel 12 to rotate through the driving motor, and then the eccentric wheel 12 pushes the slider 14 to compress the spring 15, and during the sliding process of the slider 14, it will control the electromagnet 19 to connect the metal block 20 to slide synchronously away from the elastic membrane 3.

[0063] The metal block 20 then pulls the elastic membrane 3 to deform on the side of the barrel 2. When the eccentric wheel 12 continues to rotate and the eccentric wheel 12 cannot contact the inclined surface of the slider 14, the slider 14 will quickly return to its original position under the elastic force of the spring 15, thereby quickly returning the elastic membrane 3 to its original position under the elastic force, generating a pressure wave.

[0064] Furthermore, by actively controlling the power-off of the electromagnet 19 , the elastic membrane 3 can be released at different deformation degrees, thereby generating pressure waves of different sizes.

[0065] Among them, small pressure waves are suitable for fine particles or high-viscosity grinding fluids. Through gentle disturbances, they promote uniform suspension of particles and avoid particle breakage or agglomeration caused by violent disturbances. Large pressure waves are suitable for large particles or low-viscosity grinding fluids. Through stronger disturbances, they break the agglomeration between particles, improve dispersion efficiency, and make the grinding fluid more uniform.

[0066] In addition, small pressure waves help maintain a relatively stable temperature environment, which is suitable for processes that require fine temperature control, such as precision grinding or processing of heat-sensitive materials.

[0067] Large pressure waves increase the frequency of collisions between liquid molecules, speeding up heat transfer and are suitable for situations where rapid heating is required, such as high-temperature grinding.

[0068] The two sets of sliders 14 in the pressure wave generating drive mechanism are distributed in a mirror image, so that when the eccentric wheel 12 rotates in a circle, the two sets of pressure wave generating mechanisms can be periodically controlled to operate synchronously.

[0069] The difference is that two sets of side mounting frames 7 are connected to the surface of the mounting platform 1, and the two sets of side mounting frames 7 are distributed on both sides of the barrel body 2; the two sets of side mounting frames 7 are rotatably connected with the transmission shaft 8, and the two sets of sealing bodies 4 in the two sets of pressure wave generating mechanisms arranged on both sides of the barrel body 2 are inserted with universal joints 5, and the two sets of universal joints 5 are respectively rotatably connected to the transmission shaft 8 on the same side.

[0070] One end of the two sets of transmission shafts 8 inserted in the barrel 2 is respectively connected to the two sides of the central axis 6. A motor 9 is installed on the surface of a set of side mounting frames 7, and the output shaft of the motor 9 is connected to the transmission shaft 8 in a transmission manner.

[0071] When the pressure wave generating mechanism emits pressure waves into the grinding liquid in the barrel body 2, the motor 9 is turned on to run, and the motor 9 drives the transmission shaft 8 to rotate, and then connects the universal shaft 5 and the central shaft 6 to rotate synchronously.

[0072] The surface of the central shaft 6 is connected to a stirring roller 10 located inside the barrel 2. The stirring roller 10 rotates inside the barrel 2 to stir the grinding liquid inside the barrel 2. The rotation of the stirring roller 10 directly pushes the grinding liquid to flow inside the barrel 2, effectively preventing particle sedimentation and maintaining the uniformity of the grinding liquid.

[0073] The intermittently generated pressure waves further disturb the grinding fluid, enhancing the particle suspension and achieving a more uniform particle distribution. The evenly distributed particles in the grinding fluid form a highly efficient heat-conducting network, increasing effective thermal conductivity, accelerating heat diffusion, and significantly reducing localized overheating areas. This allows for more uniform temperature regulation of the grinding fluid within barrel 2. This also eliminates adiabatic islands caused by particle agglomeration, keeping the maximum temperature difference within barrel 2 within a narrow range and maintaining fluid viscosity stability.

[0074] When the electromagnet 19 pulls the metal block 20 to move and controls the elastic membrane 3 to deform, the sealing body 4 slides on the surface of the universal shaft 5, thereby maintaining the seal inside the barrel body 2 and preventing leakage of the grinding liquid.

[0075] It is worth noting that two sets of pressure wave change driving mechanisms are also installed on the surface of the mounting platform 1. When the electromagnet 19 pulls the metal block 20 to slide and controls the elastic membrane 3 to deform, the pressure wave change driving mechanism will control the sliding direction of the metal block 20, thereby changing the deformation angle of the elastic membrane 3 and adjusting the angle of the ultrasonic wave emitted by the elastic membrane 3.

[0076] Pressure waves at different angles can more comprehensively cover the internal space of the barrel 2, avoiding dead zones or local sedimentation in certain areas due to insufficient pressure wave coverage; at the same time, by changing the angle, the pressure waves can penetrate at different depths and directions, allowing the particles to move more evenly in three-dimensional space, thereby improving the overall mixing effect.

[0077] Furthermore, pressure waves at different angles cause the particles to experience disturbances of varying strengths and directions, increasing the randomness of their motion. This random motion helps the particles participate more fully in energy exchange, improving temperature control. Furthermore, if pressure waves were always emitted at the same angle, they could result in excessive energy input in some areas and insufficient energy in others. By varying the angle, energy can be evenly distributed within the barrel 2, avoiding localized overheating and energy waste.

[0078] It should be further explained that the pressure wave change driving mechanism includes a side platform 21 installed on the mounting platform 1, and a mounting groove 22 is provided inside the side platform 21. A swivel 23 is rotatably connected inside the mounting groove 22, and the swivel 23 and the barrel body 2 are distributed in concentric circles.

[0079] A limit stop 27 is connected to the side of the rotating ring 23 facing the elastic membrane 3. The limit stop 27 is shaped like a circle, with the inclined surface of the limit stop 27 facing downward. When the electromagnet 19 pulls the metal block 20 to slide outward to control the deformation of the elastic membrane 3, the metal block 20, under the pulling force of the electromagnet 19, will come into contact with the inclined surface below the limit stop 27. As the sliding distance of the metal block 20 increases, the limit stop 27 will exert a greater restriction on the metal block 20. Because the elastic membrane 3 is soft and the metal block 20 is mounted on the surface of the universal shaft 5.

[0080] As a result, the metal block 20 is tilted under the limiting action of the limiting block 27, thereby changing the deformation direction of the elastic membrane 3 and the direction of the pressure wave that is ultimately generated.

[0081] Specifically, a side plate 25 is connected to the side table 21, and a motor 9 is installed on the surface of the side plate 25. A control gear 26 is connected to the output shaft of the motor 9. The control gear 26 and the teeth 24 set on the surface of the rotating ring 23 are connected in transmission. When the motor 9 drives the control gear 26 to engage the teeth 24 to rotate, it will control the rotating ring 23 to rotate in the installation groove 22 and adjust the position of the limit block 27.

[0082] As a result, the metal block 20 will be limited and blocked in different directions by the limit block 27 during the sliding process, thereby generating and emitting pressure waves at different angles.

[0083] And when the angle of the metal block 20 changes under the limiting action of the limit block 27, the universal joint 5 will be synchronously controlled to rotate between the transmission shaft 8 and the central shaft 6. Through the connecting action of the universal joint 5, the central shaft 6 can keep controlling the stirring roller 10 to rotate continuously.

[0084] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
