Description

Technical Field

[0001] The invention belongs to the technical field of antifreeze production, and in particular relates to an automatic antifreeze blending device for a hydraulic support. Background Art

[0002] Antifreeze for hydraulic supports: deionized water and ethylene glycol antifreeze are the main ingredients, with a series of additives such as preservatives, rust inhibitors, extreme pressure anti-wear agents and defoaming agents added in the middle;

[0003] Core equipment for antifreeze production: chemical stirred reactors, of which vertical stirred reactors are the most commonly used due to their versatility, ease of cleaning, and corrosion resistance;

[0004] Radial vortex: The fluid forms a local vortex flow around the agitator or in the radial direction (horizontal direction) of the reactor. The fluid rotates in a plane perpendicular to the axis with the agitator shaft as the center. That is, when the radial flow blades rotate, the blades exert a force perpendicular to the rotation plane on the fluid, causing the fluid to be ejected in the radial direction (tangential direction) at high speed. After hitting the reactor wall, the fluid is divided into two forms of movement, upward and downward. The aforementioned flow forms a low-pressure area near the agitator shaft. The peripheral fluid gathers toward the reactor wall due to centrifugal force, causing the central liquid level to be concave (vortex), thereby producing the "swirl" phenomenon;

[0005] The swirling phenomenon has the following hazard chain:

[0006] This results in insufficient uniformity in the mixing of various ingredients, leading to defective differences in product performance before and after;

[0007] Some antifreezes contain incompatible components (such as oil-soluble additives in water-based systems). Swirling can further exacerbate the stratification trend, leading to an increased risk of phase separation and affecting mixing uniformity.

[0008] The transfer efficiency decreases, affecting process stability, prolonging mixing time, increasing energy waste, and increasing equipment wear;

[0009] Risk of local concentration implosion and failure of foam control;

[0010] In addition, when the radial vortex component is greater than the axial flow component, axial stratification caused by the radial vortex occurs, further affecting the production quality of the antifreeze fluid. Summary of the Invention

[0045] Preferably, the outer wall of the force-dividing roller away from the kettle cover is evenly connected with blades, and adjacent blades are staggered and displaced. In addition, the tooth grooves on the outer walls of two adjacent blades have opposite rotation directions.

[0046] The method for balancing the swirling phenomenon inside the vertical stirred reactor is to use the above-mentioned automatic antifreeze blending device for the hydraulic support to implement balancing. The specific steps are as follows:

[0047] S1: First, the densely distributed blades sense the change in the external fluid movement form. At the same time, the radial force of the external fluid pushes the force-dividing roller to rotate in the opposite direction (with the coupling roller as a reference) by a specified angle or number of turns. At this time, the axial ring deflects the specified angle or number of turns under the synchronous action of the crank;

[0048] During this process, the interaction force between the vertical plate and the ring is ensured by the return spring. At the same time, by changing the degree of compression between the vertical plate and the return spring, the radial force balance between the blade and the external fluid is linearly unified. At the same time, through the interaction between the cam and the ejector pin, the rotation smoothness of the crank under different radial force components is further limited, and the linkage accuracy between the force-dividing roller and the coaxial ring is improved.

[0049] S2: Then, the double-sided gear ring at one end away from the water tank is linked with the decorative ring and the crank, which synchronously drives the rack to move a specified distance away from the axis of the coupling roller until the electrode column and the electrode sheet collide with each other. After that, the support is supported and guided by the surface frame to control the rack to move away from the axial ring until the rack is engaged with the double-sided gear ring on the other side (away from the water tank);

[0050] S3: Finally, the guide groove provides support and guidance to the ring pipe in the moving state. At the same time, the inclined groove provides stable moving support to the rack in the moving state. Finally, through the movement synchronization between the coaxial rings of the sun gear, the double-sided gear ring (close to the water tank) is driven by the meshing action of the sun gear and the planetary gear to drive the rack to move a specified distance in the direction of the vertical rod. In this way, in conjunction with the other movement form of the rack in the aforementioned S2, the reciprocating motion of the frame-type stirring paddle inside the kettle body is controlled (when the "swirl" phenomenon occurs around the frame-type stirring paddle).

[0051] The present invention has the following beneficial effects:

[0052] 1. The present invention uses the crank to provide real-time feedback to the axial ring, and the change in the state of the interaction force between the external blades and the flowing antifreeze liquid. When the radial component of the force between the blades and the antifreeze liquid gradually increases, the axial ring synchronously drives the double-sided gear ring (away from the water tank) to engage with the rack. The contact state between the electrode sheet and the electrode column changes the meshing state of the rack with the double-sided gear rings at different positions, thereby achieving reciprocating fine adjustment of the degree of deviation between the frame-type stirring paddle inside the kettle body and the axis of the kettle body, and improving the movement form between the frame-type stirring paddle and the antifreeze liquid in real time, reducing the occurrence of the "swirling" phenomenon, changing the eccentric state of the frame-type stirring paddle in different time periods, breaking the circumferentially symmetrical flow field of the antifreeze liquid, reducing the synchronous rotation trend of the antifreeze liquid with the frame-type stirring paddle, and promoting the antifreeze liquid to generate radial diversion and axial circulation while flowing circumferentially;

[0053] In addition, real-time changes in the deviation state between the frame-type stirring paddle and the axis of the kettle body help to make the gap between the frame-type stirring paddle and the inner wall of the kettle body non-uniform (the gap near the wall is small, and the gap far from the wall is large), prompting the area with smaller gaps to generate stronger shear forces, suppressing the circumferentially symmetrical flow state of the antifreeze in the boundary layer, and at the same time, allowing the antifreeze to reflux in the area with larger gaps, promoting axial mixing, effectively dispersing the antifreeze layer, and reducing the tendency to swirl.

[0054] 2. The present invention uses the interaction between the cam and the ejector pin, and the interaction between the vertical plate and the return spring, to gradiently coordinate the stable motion relationship between the external blades and the antifreeze under the change of the radial component gradient, and accurately adjust the deviation state between the axis of the frame-type stirring paddle and the axis of the kettle body. While effectively suppressing the swirling phenomenon, it avoids the instantaneous and violent collision between the frame-type stirring paddle and the antifreeze in unit time, which helps to increase the service life of the frame-type stirring paddle, achieve a more efficient stirring method, and reduce the defect difference between the products before and after the antifreeze.

The outer wall of the kettle body 21 is uniformly clamped and installed with angle brackets 18 in the circumferential direction.

[0083] Reference Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 It can be seen that the feedback unit 4 includes: a separate bin 41, which is mounted on the middle position of the end face of the cylinder ring 29 close to the water separation bin 31 through a bearing rotation fit; a decorative ring 42, which is snap-fitted and mounted on the outer wall of the double-sided gear ring 313 at the end away from the water separation bin 31; in addition, the decorative ring 42 is snap-fitted and mounted on the outer wall of the coupling roller 23; a bridging column 43, which is symmetrically snap-fitted and mounted on both ends of the end face of the decorative ring 42 away from the water separation bin 31; a crank 44, which is snap-fitted and mounted on the two ends of the bridging column 43 away from the decorative ring 42; in addition, the crank 44 is snap-fitted and mounted on the ends of the two bridging columns 43 away from the decorative ring 42; in addition, the crank 44 is snap-fitted and mounted on the outer wall of the coupling roller 23; The arc groove on the outer wall of the storage bin 41 is slidably mounted; the vertical plate 45 is snap-fitted and mounted in the middle position of the outer wall of one of the bridging columns 43; the ring 46 is snap-fitted and mounted at the axis of the storage bin 41 through the mounting plate; in addition, the ring 46 and the vertical plate 45 are slidably mounted; the return spring 47 is sleeved and mounted on the outer wall of the ring 46; the force-dividing roller 48 is snap-fitted and mounted on the end of the crank 44 away from the axis of the axial ring 1; the ring bin 49 is slidably mounted on the outer side of the end surface of the shaft disc 25 away from the water bin 31, and the force-dividing roller 48 passes through the ring bin 49;

[0084] The outer wall of the force-dividing roller 48 at one end away from the kettle cover 22 is evenly connected with blades 411, and adjacent blades 411 are staggered and arranged in a staggered manner. In addition, the tooth grooves on the outer walls of two adjacent blades 411 have opposite rotation directions.

[0085] Simple process of adding antifreeze liquid into the interior of the kettle 21:

[0086] First, the equipment is inspected and cleaned: that is, the reactor is inspected to confirm the sealing state between the coupling roller 23 and the inner magnetic steel body 13, and there is no leakage;

[0087] Clean the kettle 21 and rinse the inner wall of the reactor with deionized water to ensure that there is no oil stain or impurity residue. If necessary, disinfect it with a dilute acid / alkali solution and then rinse it clean;

[0088] Next, the materials are added: liquid raw materials (deionized water, ethylene glycol, defoamer, part of the corrosion inhibitor, pH adjuster and colorant) are added to the interior of the kettle 21 through the liquid inlet pipe 14. During this process, at appropriate times, corresponding solid raw materials (part of the corrosion inhibitor, preservative and thickener, etc.) are added to the interior of the kettle 21 through the feed pipe 15.

[0089] Finally, stirring, temperature control, and discharging: If the raw materials are all room-temperature liquids, at room temperature, the linkage between the coupling roller 23, the cylindrical ring 29, and the shaft disc 25 causes the frame-type stirring paddle 24 to stir the internal raw materials for a specified time to ensure full fusion. Afterwards, if the corrosion inhibitor is a solid and difficult to dissolve, hot water or steam can be introduced through the reactor jacket to raise the temperature of the materials to a specified temperature range, and stirred until completely dissolved before cooling to room temperature.

[0090] In a specific implementation, the asynchronous motor 12 can drive the coupling roller 23 to drive the cylindrical ring 29 to rotate (the outer magnetic steel body and the inner magnetic steel body 13 form a magnetic transmission device, which realizes contactless transmission between the asynchronous motor 12 and the coupling roller 23, solves the leakage problem existing in traditional mechanical seals, reduces mechanical wear, and increases the service life of the coupling roller 23);

[0091] Connect the filter cloth or precision filter through the discharge valve 17 at the bottom of the reactor to remove any remaining impurities (such as undissolved solid particles) and transfer the finished antifreeze liquid to a storage tank or directly fill it into a plastic barrel or bottle, and label it with information such as the category, freezing point and production date;

[0092] The grid support 16 provides stable rigid support to the kettle body 21, improving the operational stability of the vertical stirred reactor. It also ensures the space margin between the kettle body 21 and the external receiving surface, rationally arranges the discharge valve 17, and reduces the contact between the external environment and the discharge valve 17 port to a certain extent, reducing the difficulty of subsequent filtration and filling.

[0093] Angle bracket 18: On the one hand, it provides a stable fulcrum for the transport personnel, reducing the difficulty of transportation; on the other hand, it facilitates the user to implement a stable connection between the kettle body 21 and the external fixing parts;

[0094] Real-time feedback process of blade 411 on the radial force component under the motion state of external antifreeze fluid:

[0095] Precondition: Within a unit of time, the frame-type stirring blade 24 rotates at a certain speed for a specified number of revolutions, and when the rotation state is stable:

[0096] First, the densely distributed blades 411 increase the contact area between the blades 411 and the external antifreeze liquid, thereby improving the feedback accuracy of the blades 411 to changes in the movement form of the external antifreeze liquid. In a specific implementation, the tooth grooves on the outside of the blades 411 (the tooth grooves between the outer walls of adjacent blades 411 are centrally symmetrical and staggered and continuously distributed, thereby enhancing the local axial guide mixing and shearing effect under the radial stirring state) can provide the external antifreeze liquid with a local axial shearing movement form different from the radial flow, thereby promoting the local antifreeze liquid to circulate back and forth along the axial direction, reducing stratification, improving the mixing uniformity between the various raw materials of the antifreeze liquid, and improving the final product quality of the antifreeze liquid;

[0097] Then, the force-dividing roller 48 slides a specified angle along the inner wall of the indexing groove 28 under the support of the shaft disc 25 (the indexing groove 28 is fully covered by the ring groove, which reduces the cross contamination of the antifreeze liquid at both ends of the shaft disc 25 and increases the service life of the corresponding components of the control unit 3 and the feedback unit 4);

[0098] Finally, the force-dividing roller 48 swings (at a small angle), prompting the crank 44 to control the decorative ring 42, driving the axial ring 1 to rotate at a small angle;

[0099] During this process, the ring 46 and the vertical plate 45 cooperate to stabilize the rotation accuracy of the crank 44. At the same time, the return spring 47 applies a reverse force to the crank 44, and the reverse force is proportional to the depth of action of the vertical plate 45 and the return spring 47.

[0100] It is hereby explained that during the stirring process, the radial components of force acting on the stirring roller at the end away from the axis of the reactor (outside) and the end close to the axis (inside) are usually distributed in an increasing manner, that is, the force on the outside is greater than that on the inside (the outside is close to the reactor wall, the fluid is constrained by the wall, the turbulence intensity and pressure fluctuations are enhanced, and the radial component of force on the outside is further increased). Therefore, through the gradient change of the interaction between the aforementioned return spring 47 and the vertical plate 45, positive feedback gradient regulation is achieved with the radial component of force between the blade 411 and the antifreeze liquid.

[0103] Reference Figure 7 and Figure 10 It can be seen that the rack 321 is installed on the end surface of the angle plate 35 away from the water tank 31 in a sliding and snap-fit ​​manner, and the rack 321 is meshed with the double-sided gear ring 313 on the side away from the water tank 31. A base 322 is installed on both ends of the rack 321. A ring tube 323 is installed on the end surface of the base 322 away from the rack 321 at one end.

An oblique groove 327 connected to the guide groove 326 is provided on the outer wall of the vertical rod 325, and the depth of the oblique groove 327 decreases gradually. In addition, the cross-section of the oblique groove 327 is circular.

[0104] Reference Figure 7 、 Figure 9 and Figure 10 It can be seen that a noodle frame 331 is provided in the space on the other side of the rack 321. The vertical section of the noodle frame 331 is slidably engaged with a support 332, and a U-shaped frame 333 is installed on the end face of the support 332 away from the rack 321. A telescopic elastic rod 334 is slidably engaged with the support 332. The electrode sheet 335 is mounted on the end of the telescopic elastic rod 334 close to the rack 321, and the electrode column 336 is mounted on the other end of the base 322 close to the noodle frame 331. An end wedge plate 337 is mounted on the end of the telescopic elastic rod 334 away from the support 332, and a bottom wedge plate 338 is mounted on the horizontal section of the noodle frame 331 close to the water tank 31.

[0105] Reference Figure 3 and Figure 4It can be seen that a water separation ring 341 is clamped and installed on the end face of the water separation tank 31 close to the axial ring 1, and a positioning column 342 is slidingly clamped and installed on the end face of the water separation ring 341 away from the axial ring 1. The end of the positioning column 342 away from the axial ring 1 is rotated and fitted with a push plate 343 through a coil spring. A scraper 344 is clamped and installed on the end of the positioning column 342 close to the water separation ring 341, and the cross-section of the scraper 344 is triangular, and side halberds 345 are clamped and installed at both ends of the scraper 344.

[0106] When the radial force between the blade 411 and the external antifreeze liquid changes, the reciprocating fine adjustment process between the axis of the frame stirring blade 24 and the axis of the kettle body 21 within the specified range is as follows:

[0107] The frame-type stirring paddle 24 moves toward the force-dividing roller 48 (in the initial state, the double-sided gear ring 313 (the end away from the water tank 31) is meshed with the rack 321):

[0108] First, under the control of the crank 44, the decorative ring 42 synchronously drives the double-sided gear ring 313 (away from the water tank 31) to rotate. The rack 321, under the meshing action of the double-sided gear ring 313, controls the base 322 to drive the electrode column 336 to move toward the electrode sheet 335 (during this process, the angle plate 35 provides stable support for the rack 321, and the spring ball rod 324 and the guide groove 326 are engaged to ensure the positive fit between the electrode column 336 and the electrode sheet 335) until they are in contact.

[0109] Next, through the synchronization of the movement between the angle plate 35 and the corner column 32 (the center keyway 26 provides guide support for the corner column 32, and the center keyway 26 is covered by the water separation tank 31 to prevent the antifreeze inside the kettle 21 from volatilizing into the operating area of ​​the control unit 3 during the production process; similarly, the side keyways 27 provide guidance for the movement of the vertical column 36 to improve the movement stability of the angle plate 35), the water separation tank 31 is controlled to drive the frame-type stirring paddle 24 to follow the rack 321 to move a certain distance in the direction of the force-dividing roller 48, thereby disrupting the motion flow field of the frame-type stirring paddle 24 in the current stable state and suppressing the occurrence of the "swirl" phenomenon;

[0110] Finally, through the electrical contact connection between the electrode column 336 and the electrode sheet 335 (and in specific implementation, a movable clamping method can be used to achieve detachable plug-in cooperation between the electrode column 336 and the electrode sheet 335; at the same time, the contact signal between the electrode column 336 and the electrode sheet 335 can be analyzed by an external PLC control system, and this can be used as an initial signal for the support 332 to start or stop moving), the support 332 is prompted to synchronously drive the rack 321 to move toward the shaft disk 25. In specific implementation, the support 332 can be driven to move by an electric slider, and the height of the control interface ring 38 is consistent with the double-sided gear ring 313. When the external calculation electrode column 336 contacts the electrode sheet 335, the tooth surfaces on both sides are completely overlapped, ensuring that the rack 321 is disengaged from the double-sided gear ring 313 (away from the water separation tank 31) and just engages with the double-sided gear ring 313 (close to the water separation tank 31) at the same time.

[0111] During this process, due to the elasticity of the spring ball rod 324 and the gradient change in the depth of the inclined groove 327, the vertical rod 325 always provides stable support to the rack 321 when the rack 321 moves along its axis (the amount of compression of the spring ball rod 324 remains unchanged);

[0112] The frame-type stirring blade 24 moves away from the force-dividing roller 48:

[0113] The bottom wedge plate 338 provides a movement limit to the end wedge plate 337 until the electrode column 336 separates from the electrode sheet 335. At this time, the electrode column 336 is still partially inside the support 332. That is, the movement distance between the natural state and the maximum elastic variable state of the telescopic elastic rod 334 is the maximum movement distance of the rack 321 away from the force-dividing roller 48. When the electrode column 336 separates from the electrode sheet 335, the support 332 controls the rack 321 to move away from the shaft disk 25 again until it returns to the initial position.

[0114] In a specific implementation, the axial ring 1 controls the rotation of the sun gear 311. Under the action of the sun gear 311, the planetary gears 312 engage the double-sided ring gear 313, causing the current double-sided ring gear 313 to rotate in the opposite direction of the previous double-sided ring gear 313 until the electrode column 336 and the electrode sheet 335 are disconnected.

[0115] In a specific implementation, through the mouth ring 314, the ear seat 315, and the tooth plate 316 (in a specific implementation, a limiting column is provided on the outer wall of the mouth ring 314 on one side of the tooth plate 316, so that the tooth plate 316 can rotate in one direction, forming a ratchet and pawl structure with the double-sided gear ring 313. At the same time, the aforementioned ratchet and pawl structure can be added in the same proportion on the side of the face ring 37 without obstructing the meshing area of ​​the sun gear 311 and the planetary gear 312, further avoiding the unidirectional adjustment of the front and rear position of the frame-type stirring paddle 24 under the condition of the radial component force fluctuation of the antifreeze liquid inside the kettle body 21);

[0116] For the cleaning process of the contact area between the water tank 31 and the coaxial disk 25 in the moving state:

[0117] The water separation ring 341 provides stable support to the positioning column 342. During implementation, the positioning column 342 can be driven to move by the electric slider, and the top force plate 343 can ensure the movement accuracy of the positioning column 342. The antifreeze in the edge area of ​​the water separation ring 341 is scraped off by the scraper 344, and the scraper 344 with a triangular cross-section shape is used to move the scraped antifreeze to the outer wall of the water separation ring 341, thereby reducing secondary pollution caused by the accumulation of antifreeze (through the non-contact between the side halberd 345 and the coaxial disk 25, the antifreeze in the silted state is further guided and "excluded").

[0118] The present invention provides an automatic antifreeze mixing device for a hydraulic support as follows: Step 1: First, densely distributed paddles 411 sense changes in the motion of an external fluid. Simultaneously, the radial force of the external fluid drives the force-dividing roller 48 to rotate in the opposite direction (with the coupling roller 23 as a reference) by a specified angle or number of turns. At this time, the axial ring 1 deflects the specified angle or number of turns under the synchronous action of the crank 44;

[0119] During this process, the interaction force between the vertical plate 45 and the ring 46 is ensured by the return spring 47. At the same time, by changing the compression degree between the vertical plate 45 and the return spring 47, the radial force between the blade 411 and the external fluid is linearly unified. At the same time, through the interaction between the cam 413 and the ejector pin 415, the rotation smoothness of the crank 44 under different radial force components is further limited, thereby improving the linkage accuracy between the force component roller 48 and the axial ring 1.

[0120] Step 2: The double-sided gear ring 313 at one end away from the water tank 31, in conjunction with the decorative ring 42 and the crank 44, simultaneously causes the rack 321 to move a specified distance away from the axis of the coupling roller 23 until the electrode column 336 contacts the electrode sheet 335. Thereafter, the support 332, supported and guided by the surface frame 331, controls the rack 321 to move away from the axial ring 1 until the rack 321 engages with the double-sided gear ring 313 on the other side (away from the water tank 31).

[0121] Step 3: Finally, the guide groove 326 is used to provide support and guidance for the ring tube 323 in the moving state. At the same time, the inclined groove 327 is used to provide stable moving support for the rack 321 in the moving state. Finally, through the movement synchronization between the coaxial ring 1 of the sun gear 311, the double-sided ring gear 313 (close to the water tank 31) is prompted to drive the rack 321 to move a specified distance in the direction of the vertical rod 325 under the meshing action of the sun gear 311 and the planetary gear 312. In this way, in conjunction with the other movement form of the rack 321 in the aforementioned S2, the reciprocating motion of the frame-type stirring paddle 24 inside the kettle body 21 is controlled (when the "swirl" phenomenon occurs around the frame-type stirring paddle 24).
