Description

Technical fields:

[0001] This utility model belongs to the field of printing paste preparation technology, and specifically refers to a printing paste auxiliary production equipment. Background technology:

[0002] In the textile printing and dyeing industry, printing paste auxiliaries are key components affecting printing quality. Their properties (such as dispersibility, stability, viscosity, and color fastness) directly determine the uniformity and color vibrancy of the printing effect. Traditional paste auxiliary production equipment typically uses a single stirring structure (such as a paddle or anchor stirrer) combined with external jacket heating or cooling to control the reaction temperature. However, existing equipment of this type has the following drawbacks: 1. Traditional jacket heating / cooling systems cover the entire tank, making it difficult to achieve zoned temperature control. During the paste reaction, local overheating or uneven cooling can easily lead to component decomposition, agglomeration, or abnormal viscosity, affecting product stability. 2. A single stirring structure cannot simultaneously meet the requirements of high-speed dispersion, wall scraping and anti-sticking, and homogenization emulsification. High-viscosity pastes are prone to stratification, particle sedimentation, or wall agglomeration, requiring multiple rework processes and resulting in low production efficiency. Utility model content:

[0003] The purpose of this invention is to provide a printing paste additive production equipment that can achieve precise temperature control in the upper and lower sections of the tank and improve mixing uniformity and reaction efficiency through multi-stage stirring.

[0004] This utility model is implemented as follows:

[0005] A printing paste auxiliary agent production device includes an installation platform, on which a tank is mounted. A heating shell is mounted on the lower outer wall of the tank, forming an independent heating cavity between the heating shell and the lower outer wall of the tank. A heat transfer oil inlet is provided on the heating cavity. A cooling shell is mounted on the upper part of the tank, forming an independent cooling cavity between the cooling shell and the upper outer wall of the tank. A cooling water inlet is provided on the cooling cavity. A high-speed fan stirring head, a wall-scraping stirring head, and a homogenizing emulsifying stirring head are mounted inside the tank. The high-speed fan stirring head, the wall-scraping stirring head, and the homogenizing emulsifying stirring head are driven to rotate by a first motor, a second motor, and a third motor, respectively. Several raw material feeding pipes communicating with the inner cavity of the tank are also provided on the tank.

[0006] In the above-mentioned printing paste auxiliary production equipment, the upper end of the tank is provided with an opening, and an observation window is provided at the opening that can be opened and closed.

[0008] In the above-mentioned printing paste auxiliary production equipment, the first impeller and the second impeller include an impeller body and fan blades distributed circumferentially along the outer edge of the impeller body.

After installation, the first scraper arm and the second scraper arm form a symmetrical U-shape. The first scraper arm and the second scraper arm can scrape off the paste on the inner side wall of the tank. The second rotating shaft is driven to rotate by a second motor.

[0011] In the above-mentioned printing paste auxiliary production equipment, the cross-sections of the first scraper arm and the second scraper arm are triangular, with the base of the triangle located near the inner wall of the tank. Stirring blades are arranged at intervals along the vertical direction on one of the inclined surfaces of the first scraper arm and the second scraper arm.

[0012] In the above-mentioned printing paste auxiliary production equipment, the homogenizing emulsifying stirring head includes a third rotating shaft, a base plate is provided at the lower end of the third rotating shaft, the base plate is installed in the inner cavity of the tank by a plurality of circumferentially distributed mounting columns, the lower end of the third rotating shaft is rotatably connected to the base plate, a third impeller is provided at one end of the third rotating shaft near the base plate, and the third rotating shaft is driven to rotate by a third motor.

[0013] In the above-mentioned printing paste auxiliary production equipment, the installation platform includes a floor slab and columns supporting the floor slab.

[0019] The present invention will be further described below with reference to specific embodiments:

[0020] like Figure 1 and Figure 2 As shown, this utility model provides a printing paste auxiliary agent production equipment. The printing paste auxiliary agent production equipment includes an installation platform, on which a tank 1 is set. A heating shell 2 is set on the outer wall of the lower end of the tank 1, forming an independent heating cavity between the heating shell 2 and the outer wall of the lower end of the tank 1. A heat transfer oil inlet is set on the heating cavity. A cooling shell 3 is set on the upper part of the tank 1, forming an independent cooling cavity between the cooling shell 3 and the outer wall of the upper part of the tank 1. A cooling water inlet is set on the cooling cavity. A high-speed fan stirring head, a wall scraping stirring head, and a homogenizing emulsifying stirring head are set inside the tank 1. The high-speed fan stirring head, the wall scraping stirring head, and the homogenizing emulsifying stirring head are driven to rotate by a first motor 4, a second motor 5, and a third motor 6, respectively. Several raw material feeding pipes communicating with the inner cavity 7 of the tank are also set on the tank 1.

[0021] This invention utilizes a raw material feeding pipeline to deliver raw materials of different components to the inner cavity 7 of the tank in stages or simultaneously according to process requirements, improving the accuracy of the mixing ratio. The production of printing paste additives is achieved through a high-speed fan stirring head, a wall-scraping stirring head, and a homogenizing emulsifying stirring head. During this process, heat transfer oil is added to the heating chamber for heating, and cooling water or ice water is added to the cooling chamber for cooling, achieving zoned temperature control to meet the temperature requirements of different reaction stages. The homogenized paste is discharged through a valve at the bottom of the tank and can be directly used in the printing process.

[0022] It should be noted that this utility model is relatively large. The installation platform includes a floor slab 8 and supporting columns. A through hole is provided on the floor slab 8, through which the tank 1 passes. The lower end of the tank 1 extends below the floor slab 8 through the through hole, and the upper end of the tank 1 extends above the floor slab 8. This design eliminates the need for climbing, facilitating maintenance and operation.

[0023] This invention achieves precise temperature control in the upper and lower sections of tank 1 through independent heating and cooling chambers. This allows for rapid heating to promote the reaction while timely cooling to prevent overheating. The heating and cooling chambers are in direct contact with the outer wall of tank 1, resulting in high heat transfer efficiency and low energy consumption. It adapts to the temperature requirements of different stages of slurry production, improving reaction efficiency and product quality. Specifically, a high-speed fan stirring head enables rapid mixing and airflow disturbance of the slurry; a wall-scraping stirring head prevents sticking and coking, ensuring uniform heat transfer; and a homogenizing emulsifying stirring head refines particles, improving slurry uniformity and stability. Three motors independently drive different stirring heads, allowing for flexible adjustment of speed and combination to meet diverse process requirements. Furthermore, multiple raw material feed pipelines support simultaneous or staged feeding of multiple components, reducing manual intervention and making it suitable for continuous production.

[0024] For easy observation, the upper end of the tank 1 is provided with an opening, and an observation window 9 is provided at the opening that can be opened and closed.

[0025] like Figure 2 As shown, the high-speed fan stirring head includes a first rotating shaft 10, on which a first impeller 11 and a second impeller 12 are arranged axially at intervals. The first rotating shaft 10 is driven to rotate by a first motor 4.

[0026] Specifically, the first impeller 11 and the second impeller 12 include an impeller body and blades distributed circumferentially along the outer edge of the impeller body. The blades include an upwardly bent first blade 13 and a downwardly bent second blade 14. The first blade 13 and the second blade 14 are arranged at intervals. The first impeller 11 and the second impeller 12 are used to generate strong shear force to break up particle agglomerates.

[0027] Furthermore, a mounting base is provided at the middle of the first impeller 11 and the second impeller 12. Several radially arranged fasteners are distributed circumferentially on the mounting base. The first impeller 11 and the second impeller 12 are fixed to the first rotating shaft 10 by the fasteners. The first impeller 11 and the second impeller 12 are detachably fixed to the first rotating shaft 10, facilitating replacement and adjustment of the vertical position of the first impeller 11 and the second impeller 12 on the first rotating shaft 10.

[0028] Furthermore, the wall-scraping stirring head of this utility model includes a second rotating shaft 15 and a first scraper arm 16 and a second scraper arm 17 disposed at the lower end of the second rotating shaft 15. A first flange and a second flange are respectively provided at one end of the first scraper arm 16 and the second scraper arm 17. The first flange and the second flange are connected to each other by fasteners and fixed on the second rotating shaft 15. After installation, the first scraper arm 16 and the second scraper arm 17 form a symmetrical U-shape. The first scraper arm 16 and the second scraper arm 17 can scrape off the slurry on the inner wall of the tank 1. The second rotating shaft 15 is driven to rotate by a second motor 5.

[0029] As can be seen from the above, the first scraper arm 16 and the second scraper arm 17 of this utility model can be replaced individually after wear, reducing maintenance costs. The U-shaped structure distributes forces evenly, reducing the risk of uneven wear on the second rotating shaft 15. Furthermore, the first scraper arm 16 and the second scraper arm 17 are connected by the first flange and the second flange without welding, making disassembly convenient.

[0030] Typically, the gap between the first scraper arm 16, the second scraper arm 17 and the inner wall of the tank body 1 is 1-5mm, which ensures the scraping effect while avoiding hard friction that could cause the equipment to jam.

[0031] Furthermore, the first scraper arm 16 and the second scraper arm 17 of this invention have triangular cross-sections, with the base of the triangle positioned near the inner wall of the tank 1. Stirring blades 18 are spaced apart along the vertical direction on one of the inclined surfaces of the first scraper arm 16 and the second scraper arm 17. The inclined structure of the first scraper arm 16 and the second scraper arm 17 prevents slurry from accumulating on the scraper wall surface. Combined with centrifugal force, a self-cleaning effect is achieved, reducing the frequency of manual cleaning. The intermittent distribution of the stirring blades 18 further reduces the risk of adhesion.

[0032] Furthermore, the homogenizing emulsifying stirring head of this invention includes a third rotating shaft 19, with a base 20 disposed at the lower end of the third rotating shaft 19. The base 20 is mounted on the inner cavity 7 of the tank via a plurality of circumferentially distributed mounting posts 21. The lower end of the third rotating shaft 19 is rotatably connected to the base 20. A third impeller 22 is disposed on the third rotating shaft 19 near the end of the base 20. The third rotating shaft 19 is driven to rotate by a third motor 6. Generally, the third impeller 22 adopts an airfoil or turbine design, reducing no-load power consumption while achieving efficient shearing.

[0033] As can be seen from the above, the chassis 20 of this utility model is located at the bottom of the tank 1, which can guide the slurry to circulate upward and avoid the sedimentation of solid particles; the mounting columns 21 are evenly distributed, which not only supports the stability of the chassis 20, but also avoids the formation of dead flow corners, ensuring the homogenization of the slurry in the tank; in addition, the chassis 20 is fixed by the mounting columns 21, forming a narrow high shear zone with the rotating third impeller 22, in which the slurry undergoes multiple shearing, impact and cavitation effects in the gap, realizing ultra-fine emulsification.

[0034] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
