Description

Technical Field

[0001] This invention relates to the field of mixing in the production of processing auxiliaries, and more specifically, to a mixing apparatus and a mixing method for the production of dyeing and printing pretreatment auxiliaries. Background Technology

[0002] In the production process of pretreatment auxiliaries for dyeing and printing, mixing is one of the key steps, as its effectiveness directly affects the uniformity, stability, and final performance of the auxiliaries. Currently, the mixing equipment commonly used in this field is mostly of the stirred tank type, where a central shaft drives the stirring blades to rotate and achieve material mixing. However, in practical applications, this type of equipment has the following technical problems: Traditional mixing methods rely primarily on localized shearing and overall convection. For easily settling solid particles or high-viscosity materials, this often leads to a sediment layer forming at the bottom of the vessel, resulting in uneven mixing. Stirring blades alone are insufficient to effectively entrain and disperse the bottom sediment throughout the mixing system, affecting product uniformity. Furthermore, mixing efficiency needs improvement, especially for material systems requiring rapid dispersion and dissolution.

[0003] Many additives require specific temperatures to be maintained during mixing to promote dissolution or reaction. Traditional temperature control often uses jacketed heating / cooling methods, whose heat exchange efficiency is limited by the vessel wall area and the flow state of the material near the wall. For large-volume or high-viscosity materials, large temperature gradients can easily exist, leading to uneven temperature within the system, which affects the reaction rate and product quality. Summary of the Invention

[0004] To solve the above problems, the present invention adopts the following technical solution.

A flow guiding and circulation section is disposed inside the mixing vessel and connected to the drive section to guide the flow direction of the material inside the mixing vessel; A first cleaning unit is disposed inside the mixing vessel and connected to the drive unit to clean the inner wall of the mixing vessel; An anti-clogging cleaning section is provided within the flow circulation section to prevent clogging; A detection unit is installed inside the mixing vessel to control the operation of the anti-clogging and cleaning unit based on the temperature difference; A temperature control and heat transfer section is installed inside the flow circulation section to ensure a stable mixing temperature of the materials in the mixing vessel.

[0006] Furthermore, the driving unit includes: The first motor is mounted on the top cover of the vessel; The main shaft has one end passing through the top cover of the vessel and connected to the output end of the first motor, and the other end rotatably connected to the bottom plate of the vessel.

[0007] Furthermore, the flow guiding circulation section includes: The suction device is connected to the main shaft to draw in the solution at the bottom of the mixing vessel and to initially crush the precipitated material. The lifting cylinder is connected at its bottom end to the suction device to drive the suctioned material solution upward. Spiral blades are fitted onto the main shaft and located inside the lifting cylinder to drive the solution to flow upward. The spraying element is located at the top of the lifting cylinder to spray the sucked-in solution onto the upper part of the mixing vessel to complete the flow and circulation of the solution.

[0008] Further, the inhalation device includes: The first rotating ring is sleeved on the main shaft; The turbine blades are arranged in several groups, and the several groups of turbine blades are evenly arranged on the first rotating ring. The cutting blades are provided in several groups, and the several groups of cutting blades are evenly arranged on the inner wall of the first rotating ring; The suction cone is connected to the top of the first rotating ring.

[0009] Further, the injection element includes: The bottom end of the injection cone is connected to the top end of the lifting cylinder; The spray nozzles are provided in several groups, and the several groups of spray nozzles are opened on the spray cone to spray the solution into the upper part of the mixing vessel.

[0010] Furthermore, the first cleaning unit is provided in two sets, and the two sets of the first cleaning unit are symmetrically arranged. The first cleaning unit includes: A rotating rod, one end of which is connected to the main shaft; A sliding groove is formed inside the rotating rod; A limiting spring, one end of which is fixed inside the sliding groove; The telescopic rod is connected at one end to the other end of the limiting spring and is slidably connected within the sliding groove. The first scraper is connected to the other end of the telescopic rod; A reinforcing rib is provided, with one end connected to the telescopic rod and the other end connected to the first scraper to enhance stability.

[0011] Furthermore, the anti-clogging cleaning unit includes: A support ring is disposed on the inner wall of the lifting cylinder; The second rotating ring is placed on the support ring; The spiral grooves are provided in several groups, and the spiral grooves are evenly opened on the second rotating ring. The second scraper is connected at one end to the top of the second rotating ring and is in close contact with the inner wall of the spray cone. Several groups of electromagnetic blocks are provided, and these groups of electromagnetic blocks are evenly arranged at the bottom end of the support ring to cooperate with the second rotating ring for driving.

[0012] Furthermore, the detection unit includes: A first temperature sensor is installed on the inner wall of the lifting cylinder to detect the temperature of the solution inside the lifting cylinder; A second temperature sensor is installed on the inner wall of the mixing vessel to detect the solution temperature at the inner edge of the mixing vessel.

[0013] Furthermore, the temperature control and heat transfer unit includes: A medium placement groove is provided inside the lifting cylinder to introduce the heat-conducting medium; A heating ring is fitted inside the medium placement tank to regulate the temperature of the heat-conducting medium and ensure the temperature inside the mixing vessel.

[0014] The present invention also provides a mixing method suitable for the above-mentioned dyeing and printing pretreatment auxiliary production mixing equipment, comprising the following steps: S1: Start the first motor to drive the spindle to rotate; S2: The rotation of the main shaft drives the flow circulation section to run, so that the material solution in the mixing vessel is sucked in from the bottom by the suction component, lifted upward by the lifting cylinder, and sprayed out from the injection hole of the spray component to the upper part of the mixing vessel to form a circulation flow. S3: When the main shaft rotates, it drives the rotating rod and telescopic rod of the first cleaning part to rotate, so that the first scraper adheres to and scrapes the inner wall of the mixing vessel under the action of centrifugal force; S4: The heat-conducting medium in the medium placement tank is heated by the heating ring, and the heat is transferred to the internal flowing solution by the lifting cylinder wall to maintain a stable mixing temperature; S5: The temperature difference between the solution inside the lifting cylinder and the inner wall of the mixing vessel is monitored in real time by the first and second temperature sensors. When the temperature difference exceeds the set threshold, it is determined that the spray hole is blocked. The electromagnetic block is energized to reduce the friction between the second rotating ring and the support ring. The second rotating ring is driven to rotate by the upward flowing solution and drives the second scraper to scrape the inner wall of the spray cone to clear the blockage. When the temperature difference returns to below the set threshold, the power supply to the electromagnetic block is disconnected.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The drive unit rotates the entire flow circulation section, and its turbine blades and cutting blades powerfully suck in and crush the sediment at the bottom of the vessel. After being further sheared and lifted by the spiral blades inside the lifting cylinder, the material is ejected at high speed from the top spray nozzle, forming a strong three-dimensional circulating flow inside the vessel. This "bottom suction - crushing - lifting - top spray" circulation mode effectively solves the problems of material settling and uneven mixing in traditional stirring, achieving rapid and uniform dispersion and dissolution of the material.

[0016] The system monitors the temperature difference between the solution inside the circulation path and the edge of the vessel wall in real time using a detection unit. When the spray nozzle becomes clogged, causing a decrease in circulation flow, the temperature difference increases. Once the system detects that the temperature difference exceeds a set threshold, it automatically energizes the electromagnetic block of the anti-clogging cleaning unit, reducing the frictional resistance of the second rotating ring and causing it to rotate under fluid drive. This rotates the ring, driving the second scraper to scrape the inner wall of the spray cone, automatically clearing the blockage. This function enables online monitoring and active removal of blockages, ensuring the continuous and stable operation of the mixing circulation. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 11 As shown, a mixing device and mixing method for producing dyeing and printing pretreatment auxiliaries include: a mixing vessel 1; further comprising: a vessel top cover 101 disposed at the top of the mixing vessel 1; a vessel bottom plate 103 disposed at the bottom of the mixing vessel 1; a drive unit 2 disposed on the mixing vessel 1, passing through the vessel top cover 101 and connected to the vessel bottom plate 103; a flow guiding circulation unit 3 disposed inside the mixing vessel 1 and connected to the drive unit 2 to guide the flow direction of the material inside the mixing vessel 1; a first cleaning unit 4 disposed inside the mixing vessel 1 and connected to the drive unit 2 to clean the inner wall of the mixing vessel 1; an anti-clogging cleaning unit 5 disposed inside the flow guiding circulation unit 3 to avoid clogging; a detection unit disposed inside the mixing vessel 1 to control the operation of the anti-clogging cleaning unit 5 according to the temperature difference; and a temperature control heat transfer unit disposed inside the flow guiding circulation unit 3 to ensure the stability of the mixing temperature of the material inside the mixing vessel 1.

[0022] In this embodiment of the invention, by providing a flow guiding circulation section 3, the solution in the mixing vessel 1 can be mixed quickly and uniformly, and the driving section 2 drives the flow guiding circulation section 3 to rotate at high speed, achieving rapid and uniform mixing while efficiently dispersing and dissolving the solution; by providing a detection section and an anti-clogging cleaning section 5 in conjunction, the spray hole 302 is cleaned according to the temperature difference to prevent clogging; at the same time, a temperature control heat transfer section is provided, so that heat is exchanged through the most active material being strongly conveyed, which is much more efficient than the external jacket, and the high-speed flowing material continuously passes through the heat exchange surface, resulting in a very small temperature gradient in the entire system.

[0023] The equipment is equipped with a feed pipe 102 on the top cover 101 and a discharge pipe 104 on the bottom plate 103. A support frame 105 is installed at the bottom of the mixing vessel 1 to ensure the stability of the equipment.

[0024] like Figures 1 to 10 As shown, the drive unit 2 includes: a first motor 201, which is disposed on the top cover 101 of the vessel; and a main shaft 202, one end of which passes through the top cover 101 and is connected to the output end of the first motor 201, and the other end is rotatably connected to the bottom plate 103 of the vessel.

[0025] In this embodiment of the invention, the first motor 201 is driven to rotate, thereby driving the main shaft 202 to rotate, which in turn drives the flow circulation section 3 to rotate, thereby efficiently dispersing and uniformly mixing the solution.

[0026] like Figures 1 to 9 As shown, the flow circulation section 3 includes: a suction component connected to the main shaft 202 to suction the solution at the bottom of the mixing vessel 1 and to initially crush the precipitated material; a lifting cylinder 303 connected at its bottom to the suction component to drive the suction material solution upward; a spiral blade 304 sleeved on the main shaft 202 and located inside the lifting cylinder 303 to drive the solution to flow upward; and a spray component located at the top of the lifting cylinder 303 to spray the suction solution onto the upper end of the mixing vessel 1 to complete the flow circulation of the solution.

[0027] like Figures 5 to 9 As shown, the suction device includes: a first rotating ring 307, sleeved on the main shaft 202; turbine blades 306, arranged in several groups, the several groups of turbine blades 306 being evenly arranged on the first rotating ring 307; cutting blades 308, arranged in several groups, the several groups of cutting blades 308 being evenly arranged on the inner wall of the first rotating ring 307; and a suction cone 305, connected to the top end of the first rotating ring 307.

[0028] like Figures 5 to 9As shown, the spraying component includes: a spraying cone 301, the bottom end of which is connected to the top end of the lifting cylinder 303; and a number of spraying holes 302, which are provided on the spraying cone 301 to spray the solution into the upper part of the mixing vessel 1.

[0029] In this embodiment of the invention, the material is fed into the mixing vessel 1 through the feed pipe 102. The first motor 201 is started, driving the main shaft 202 to rotate. The main shaft 202 is fixedly connected to the spray cone 301, thereby driving the spray cone 301 to rotate, which in turn drives the lifting cylinder 303, the suction cone 305, the first rotating ring 307, and the turbine blades 306 to rotate. During operation, as the precipitate slowly settles to the bottom of the mixing vessel 1, the rotation of the turbine blades 306 shears and disperses the precipitated material. At the same time, the rotation of the turbine blades 306 generates a vortex at the bottom of the mixing vessel 1, creating a pressure difference at the position of the first rotating ring 307, thereby drawing the solution from the bottom of the first rotating ring 307. A cutting blade 308 is provided on the inner wall of the first rotating ring 307 to further shear and disperse the mixed precipitate passing through the first rotating ring 307. Under the action of water pressure, the solution flows along the first rotating ring 307 into the suction cone 305, and then flows upward along the suction cone 305 into the lifting cylinder 303. A spiral blade 304 is provided in the lifting cylinder 303 and is sleeved on the main shaft 202. It rotates with the main shaft 202, thereby driving the solution to flow upward into the spray cone 301. Finally, it is sprayed out from the spray hole 302 and returns to the upper end of the mixing vessel 1. Under the influence of the turbine blade 306, it flows downward and is finally sucked in again from the first rotating ring 307 to form a flow cycle.

[0030] The rotation of the spiral blades 304 further shears and breaks down the particles in the solution. Through the triple crushing operation, the materials can be fully mixed and the spray holes 302 are prevented from becoming clogged.

[0031] like Figures 10 to 11 As shown, the first cleaning part 4 is provided in two sets, and the two sets of the first cleaning part 4 are symmetrically arranged. The first cleaning part 4 includes: a rotating rod 401, one end of which is connected to the main shaft 202; a sliding groove 402, which is formed in the rotating rod 401; a limiting spring 403, one end of which is fixed in the sliding groove 402; a telescopic rod 404, one end of which is connected to the other end of the limiting spring 403 and is slidably connected in the sliding groove 402; a first scraper 405, which is connected to the other end of the telescopic rod 404; and a reinforcing rib 406, one end of which is connected to the telescopic rod 404 and the other end of which is connected to the first scraper 405 to enhance stability.

[0032] In this embodiment of the invention, the material is in the mixing vessel 1. Due to the lower fluidity of the solution near the inner wall of the mixing vessel 1, the material has a chance to adhere to the inner wall of the mixing vessel 1. When the main shaft 202 rotates, it drives the rotating rod 401 to rotate. The rotating rod 401 drives the telescopic rod 404 to rotate, thereby driving the first scraper 405 to rotate. During rotation, the first scraper 405 moves outward under the action of centrifugal force, thereby driving the telescopic rod 404 to move outward along the sliding groove 402. The spring extends, so that the first scraper 405 is pressed tightly against the inner wall of the mixing vessel 1 under the action of centrifugal force and rotates with the main shaft 202. The scraper continuously scrapes the inner wall; when the first motor 201 starts at low speed, the first scraper 405 and the inner wall of the mixing vessel 1 are not tightly attached, resulting in low resistance and easy start-up; when running at high speed, the adhesion force is large and the scraping force is strong; when encountering incompressible hard foreign objects, the scraper can be pushed back to avoid overload and jamming of the equipment; and the contact surface between the first scraper 405 and the inner wall of the mixing vessel 1 is made of flexible material, thereby better performing the scraping operation; when the main shaft 202 stops rotating, it loses its centrifugal effect, and the spring rebound drives the telescopic rod 404 and the first scraper 405 to move away from the inner wall of the mixing vessel 1, thereby detaching from the inner wall of the mixing vessel 1.

[0033] like Figures 5 to 9 As shown, the anti-clogging cleaning part 5 includes: a support ring 501 disposed on the inner wall of the lifting cylinder 303; a second rotating ring 502 placed on the support ring 501; a plurality of spiral grooves 503 evenly distributed on the second rotating ring 502; a second scraper 504 connected at one end to the top end of the second rotating ring 502 and in close contact with the inner wall of the spray cone cylinder 301; and a plurality of electromagnetic blocks 505 evenly distributed at the bottom end of the support ring 501 to cooperate with the second rotating ring 502 for driving.

[0034] like Figures 1 to 6 As shown, the detection unit includes: a first temperature sensor 701, disposed on the inner wall of the lifting cylinder 303, to detect the temperature of the solution inside the lifting cylinder 303; and a second temperature sensor 702, disposed on the inner wall of the mixing vessel 1, to detect the temperature of the solution at the inner edge of the mixing vessel 1.

[0035] In this embodiment of the invention, when the solution passes through the spray hole 302, particulate matter may accumulate and clog the spray port, resulting in poor flow. Under normal conditions, when the water flows upward and washes the second rotating ring 502, it will wash the spiral groove 503 of the second rotating ring 502, thereby driving the second rotating ring 502 to rotate. The rotation of the second rotating ring 502 will drive the second scraper 504 to scrape the inner wall of the spray cone 301 for preliminary cleaning. However, when a certain amount of sediment is generated and causes blockage, the impact force of the water flow is insufficient to overcome the friction of the second rotating ring 502 and the resistance generated by the blockage, and the second rotating ring 502 will stop rotating. At this time, due to the blockage, the water flow is poor. Because a temperature control and heat transfer section is provided, the temperature in the guide circulation section 3 will be similar to that in the mixing vessel 1. As the temperature difference at the inner wall increases, a first temperature sensor 701 detects the temperature inside the flow circulation section 3, and a second temperature sensor 702 checks the temperature at the inner wall of the mixing vessel 1. When the temperature difference between the two locations exceeds a certain limit, it indicates that the spray hole 302 is blocked. This energizes the electromagnetic block 505, generating magnetic force. Simultaneously, the material of the second rotating ring 502 repels the electromagnetic block 505, reducing the friction between the second rotating ring 502 and the support ring 501. This allows the water flow to drive the second ring to rotate, thereby causing the second scraper 504 to scrape the inner wall of the spray cone 301 to clear the blockage. The electromagnetic block 505 is then turned off once the temperature difference detected by the first temperature sensor 701 and the second temperature sensor 702 is stably below the limit, thus avoiding wasting resources.

[0036] like Figures 1 to 6 As shown, the temperature control and heat transfer unit includes: a medium placement tank 601, which is opened inside the lifting cylinder 303 to introduce the heat transfer medium; and a heating ring 602, which is sleeved inside the medium placement tank 601 to adjust the temperature of the heat transfer medium to ensure the temperature inside the mixing vessel 1.

[0037] In this embodiment of the invention, water or other liquids are placed in the medium placement tank 601, and the medium is heated to a specified temperature by the heating ring 602 to accommodate the reaction of the mixed solution. It also works in conjunction with the first temperature sensor 701 to achieve precise temperature control. At the same time, the temperature control and heat transfer part is set in the lifting cylinder 303. Since the flow of the solution in the lifting cylinder 303 is the most active, it is beneficial to the overall heat exchange of the solution, reducing the temperature gradient in the entire mixing vessel 1, thereby ensuring the mixing effect.

[0038] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
