Description

Technical Field

[0001] The present invention relates to the technical field of abrasive liquid supply barrels, and particularly relates to an abrasive liquid dynamic supply barrel with a constant temperature control function. Background Art

[0002] During the use of abrasive liquid, temperature control is an important factor affecting its performance and processing quality. Abrasive liquid is usually a high-viscosity oil-based liquid containing a certain amount of abrasive particles, and its viscosity and particle distribution will change significantly with temperature. In order to maintain the stability of the abrasive liquid and processing efficiency, the method of directly heating the abrasive liquid supply barrel is usually adopted to control its temperature within an appropriate range.

[0003] However, there are many deficiencies in the existing abrasive liquid supply barrels in terms of temperature control. For example, in a Chinese utility model patent with the publication number CN210613451U and the patent name of a constant temperature barrel for an abrasive of a grinding machine, it specifically discloses an infusion tube connected to a constant temperature barrel. The constant temperature barrel includes a barrel body and a stirrer disposed inside the barrel. A barrel cover is provided at the top of the barrel body, and the stirrer is connected to the barrel cover. The stirrer is connected with a heater. By providing a stirring rod with a heating function inside the abrasive barrel to stir and heat the stirring liquid, the concentration and temperature of the stirring liquid can be made uniform during the transportation process, reducing the crystallization phenomenon when the stirring liquid is discharged. The heat preservation jacket outside the delivery pipe can provide constant temperature protection for the infusion tube, reducing the temperature drop and crystallization of the stirring liquid after it leaves the constant temperature barrel and blocking the infusion tube to ensure smooth infusion.

[0004] In the above solution, by setting a heater on the side wall or bottom of the barrel body, heat is introduced into the abrasive liquid from a single point, resulting in a significantly higher temperature in the area near the heat source than in the core area, leading to uneven heat transfer, prone to local overheating or cold areas, causing 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 quickly respond to temperature changes. Moreover, direct heating is also prone to energy waste. Especially in occasions where high precision of temperature control is required, the heating system needs to run continuously, increasing energy consumption.

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

[0014] Further, a connecting rod is arranged on one side of the slider, and an L-shaped sliding table is arranged between the connecting rod and the electromagnet.

[0015] Further, a return spring for providing a reset force for the slider is sleeved on the fixing rod.

[0016] Further, side mounting frames are installed on both sides of the barrel body on the mounting table. Transmission shafts are rotatably connected in both groups of side mounting frames.

[0019] Further, the electromagnet can be selectively powered off to control the release of the elastic film at different deformation degrees.

[0038] The present invention will be further described below in conjunction with embodiments.

[0039] Embodiment:

[0040] Please refer to the attached Figures 1-8 , this solution proposes a dynamic supply liquid barrel for grinding fluid with a constant temperature control function. By arranging a horizontally distributed stirring roller 10 inside the barrel body 2 and combining with the intermittent operation of two groups of elastic membranes 3.

[0041] Through mechanical stirring and the periodic pressure waves generated by the elastic membrane 3, it promotes the dynamic flow of the grinding fluid and the uniform transfer of heat, thereby effectively improving the temperature control effect. This solution not only improves the uniformity and accuracy of temperature control, but also enhances the ability to inhibit particle sedimentation, significantly improving the stability and processing performance of the grinding fluid.

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

[0043] Specifically, the barrel body 2 is installed on the installation platform 1, which provides a firm installation foundation for the barrel body 2. When the device is working, when the stirring roller 10 stirs the grinding fluid in the barrel body 2 and at the same time the pressure wave generating mechanism emits pressure waves into the barrel body 2, it 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, ensure the stability of the grinding fluid flow field and the efficiency of pressure wave energy transfer, avoid the process parameter drift caused by the displacement of the barrel body 2, and improve the reliability of the system.

[0044] Both sides of the barrel body 2 are set to be open, and two groups of pressure wave generating mechanisms are respectively installed. When the device needs to perform constant temperature control on the grinding fluid filled in the barrel body 2, by controlling the operation of the pressure wave generating mechanism, pressure waves are generated and emitted into the grinding fluid inside the barrel body 2.

[0045] The pressure waves will propagate throughout the grinding fluid, causing the compression and expansion of the grinding fluid, and then making the particles in the grinding fluid move. The grinding fluid particles will accelerate, decelerate or change direction under the action of the pressure waves, thereby reducing particle sedimentation.

[0046] Meanwhile, due to the particle motion caused by the pressure wave, the friction between particles and between particles and liquid molecules will increase. This friction generates heat, leading to an increase in the liquid temperature. Furthermore, during the periodic motion of the pressure wave generating mechanism, mechanical energy is converted into the kinetic energy and internal energy of the grinding fluid. A part of this energy is converted into heat, further increasing the temperature of the grinding fluid and achieving the temperature control of the grinding fluid. And when the operating frequency of the pressure wave generating mechanism is high and the duration is long, heat will gradually accumulate in the grinding fluid, thereby achieving the control of the temperature rise of the grinding fluid.

[0047] More specifically, the pressure wave generating mechanism includes an elastic membrane 3 connected to the side opening of the barrel 2. The elastic membrane 3 is used to seal the side opening of the barrel 2 to prevent the leakage of the grinding fluid. Meanwhile, when the elastic membrane 3 is pulled outward and deformed under the action of an external force, the volume of the space inside the barrel 2 will increase, and the grinding fluid is sucked into the area where the elastic membrane 3 deforms, forming a local negative pressure.

[0048] When the elastic membrane 3 rebounds, the volume inside the barrel 2 decreases, causing the liquid to be squeezed out of the deformed area, forming a positive pressure. When the reciprocating motion of the elastic membrane 3 causes a periodic change in the volume of the grinding fluid inside the barrel 2, a periodic pressure change is generated in the grinding fluid.

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

[0050] It should be noted that a pressure wave generating drive mechanism is installed below the mounting table 1, which is used to control the deformation of the elastic membrane 3 on the side of the barrel 2, and then emit a pressure wave into the grinding fluid inside the barrel 2.

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

[0052] By starting the drive motor to drive the eccentric wheel 12 to rotate, and then controlling the intermittent deformation of the two groups of elastic membranes 3 through the rotation of the eccentric wheel 12, the pressure wave generating drive mechanism can drive the operation of the two groups of pressure wave generating mechanisms simultaneously, and the operating cycles of the two groups of pressure wave generating mechanisms are different. Furthermore, the periods of deformation and pressure wave emission of the two groups of elastic membranes 3 are different, and then asynchronous pressure waves are generated in the grinding fluid, 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 promotes the random movement and resuspension of particles, avoids the flow of the grinding fluid driven by a single-direction pressure wave, reduces the concentration of local shear stress, and improves the stability of the equipment.

[0054] Meanwhile, due to the asynchronous pressure waves, the energy transfer is more dispersed, less local frictional heat accumulates, and the rate of temperature rise is easier to control.

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

[0056] The slider 14 is trapezoidal and the inclined surface faces the side of the rotation direction of the eccentric wheel 12. When the eccentric wheel 12 rotates, it will abut against the inclined surface of the slider 14 and push the slider 14 to slide on the surface of the fixed rod 13.

[0057] A connecting rod 16 is connected to the surface of the slider 14. An L-shaped sliding table 17 is provided between the connecting rod 16 and the electromagnet 19. The sliding table 17 can move linearly, and an installation rod 18 is connected to its upper end. The installation rod 18 and the sliding table 14 are integrally L-shaped and connected to the electromagnet 19.

[0058] And it is connected to the sliding table 17 slidably mounted on the surface of the mounting table 1 through the connecting rod 16. Thus, when the eccentric wheel 12 drives the slider 14 to slide on the surface of the fixed rod 13, the synchronous linear sliding of the sliding table 17 can be controlled; and the inclined surface on the surface of the slider 14 faces away from the sliding table 17.

[0059] A sealing body 4 is connected to the center of the elastic membrane 3, and a metal block 20 is connected to the outer surface of the sealing body 4. When the installation rod 18 comes into contact with the metal block 20 after being energized, it will be adsorbed and fixed to the metal block 20 as a whole. A spring 15 is connected to the surface of the sealing body 4 facing the sliding table 17, and the spring 15 is sleeved on the surface of the fixed rod 13.

[0060] When the eccentric wheel 12 abuts against the inclined surface of the slider 14 and pushes the slider 14 to slide on the surface of the fixed rod 13, it will exert pressure on 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 sliding table 17 under the elastic force of the spring 15. Thus, the installation rod 18 pushes the electromagnet 19 to slide towards the metal block 20, and after the electromagnet 19 is energized, it will adsorb the metal block 20 and fix them as a whole.

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

[0063] Furthermore, the metal block 20 pulls the elastic membrane 3 to deform on the side of the barrel 2. And when the eccentric wheel 12 continues to rotate and cannot contact the inclined surface of the slider 14, the slider 14 will quickly reset under the elastic force of the spring 15. Then, the elastic membrane 3 quickly resets under the elastic force, generating a pressure wave.

[0064] Moreover, through the active power-off control of the electromagnet 19, the elastic membrane 3 can be released at different deformation degrees, thereby generating pressure waves of different magnitudes.

[0065] Among them, the small pressure wave is suitable for fine particles or high-viscosity grinding fluids, promoting the uniform suspension of particles through gentle agitation and avoiding particle breakage or agglomeration caused by violent agitation; while the large pressure wave is suitable for large particles or low-viscosity grinding fluids, breaking the agglomeration between particles through stronger agitation, improving the dispersion efficiency, and making the grinding fluid more uniform.

[0066] And the small pressure wave helps to maintain a relatively stable temperature environment and is suitable for process procedures that require precise temperature control, such as precision grinding or the treatment of heat-sensitive materials.

[0067] The large pressure wave accelerates the heat transfer speed by enhancing the collision frequency between liquid molecules and is suitable for occasions that require rapid heating, such as high-temperature grinding.

[0068] In the pressure wave generation driving mechanism, the two groups of sliders 14 are mirror-symmetrically distributed, enabling the eccentric wheel 12 to periodically control the synchronous operation of the two groups of pressure wave generating mechanisms when rotating in a circle.

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

[0070] One ends of the two transmission shafts 8 inserted into the barrel 2 are respectively connected to both sides of the central shaft 6. A motor 9 is installed on the surface of one group of side mounting frames 7, and the output shaft of the motor 9 is in transmission connection with the transmission shaft 8.

[0071] When the pressure wave generating mechanism emits pressure waves into the grinding fluid in the barrel 2, the motor 9 is started to operate, and the motor 9 drives the transmission shaft 8 to rotate, thereby connecting the universal shaft 5 and the central shaft 6 to rotate synchronously.

[0072] The surface of the central shaft 6 is connected with a stirring roller 10 located inside the barrel body 2. By rotating the stirring roller 10 inside the barrel body 2, the grinding fluid inside the barrel body 2 can be stirred. Through the rotational movement of the stirring roller 10, the grinding fluid can be directly pushed to flow inside the barrel body 2, effectively preventing particle precipitation and maintaining the uniformity of the grinding fluid;

[0073] The intermittently generated pressure wave further disturbs the grinding fluid, enhancing the suspension effect of the particles and making the particle distribution more uniform. The evenly distributed particles in the grinding fluid will form an efficient heat conduction network, improving the effective thermal conductivity, accelerating heat diffusion, significantly reducing local overheating areas, and thus making the temperature regulation of the grinding fluid in the barrel body 2 more uniform. At the same time, the adiabatic islands caused by particle agglomeration are eliminated, and the maximum temperature difference inside the barrel body 2 is controlled within a small range, maintaining the stability of the fluid viscosity.

[0074] And when the electromagnet 19 pulls the metal block 20 to move and controls the elastic membrane 3 to deform; the sealing body 4 will slide on the surface of the universal shaft 5, thereby maintaining the seal inside the barrel body 2 and avoiding the leakage of the grinding fluid.

[0075] It should be noted that two sets of pressure wave change driving mechanisms are also installed on the surface of the mounting table 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 ultrasonic wave angle emitted by the elastic membrane 3.

[0076] The pressure waves at different angles can more comprehensively cover the internal space of the barrel body 2, avoiding dead zones or local sedimentation in some areas due to insufficient pressure wave coverage; at the same time, through the angle change, the pressure wave can penetrate different depths and directions, making the particles move more uniformly in three-dimensional space and improving the overall mixing effect.

[0077] In addition, the pressure waves at different angles will cause the particles to be disturbed in different directions with different intensities and directions, thereby increasing the randomness of the particle movement. This random movement helps the particles to participate more fully in energy exchange and improve the temperature control effect. And if the pressure wave is always emitted at the same angle, it may cause too strong energy input in some areas and insufficient energy in other areas; through the angle change, the energy can be evenly distributed inside the barrel body 2, avoiding local overheating or energy waste.

[0078] What needs to be further explained is that the pressure wave change driving mechanism includes a side table 21 installed on the mounting table 1. An installation groove 22 is provided inside the side table 21, and a rotating ring 23 is rotatably connected inside the installation groove 22. The rotating ring 23 and the barrel body 2 are concentrically distributed.

[0079] One side surface of the swivel ring 23 facing the elastic membrane 3 is connected with a limit stop 27; the limit stop 27 is arranged in a shape, and the inclined surface of the limit stop 27 is arranged 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 will abut against the inclined surface below the limit stop 27 under the pulling force of the electromagnet 19, and as the sliding distance of the metal block 20 increases, the limit stop 27 will impose greater restriction on the metal block 20. Since the elastic membrane 3 is soft, and the metal block 20 is sleeved on the surface of the universal shaft 5.

[0080] Furthermore, under the limiting action of the limit stop 27, the metal block 20 will tilt, changing the direction of the deformation of the elastic membrane 3 and the direction of the finally generated pressure wave.

[0081] Specifically, a side plate 25 is connected to the side table 21, 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, and the control gear 26 is in transmission connection with the tooth pattern 24 arranged on the surface of the swivel ring 23. When the motor 9 drives the control gear 26 to engage with the tooth pattern 24 and rotate, it will control the swivel ring 23 to rotate in the installation groove 22 and adjust the position of the limit stop 27.

[0082] Furthermore, during the sliding process of the metal block 20, it will be limited and blocked by the limit stop 27 in different directions, so as to generate pressure waves at different angles and emit them.

[0083] And when the metal block 20 changes its angle under the limiting action of the limit stop 27, it will synchronously control the universal shaft 5 to rotate between the transmission shaft 8 and the central shaft 6. Through the connection function of the universal shaft 5, the central shaft 6 can be kept to control 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 it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
