Description

Technical Field

[0001] This utility model relates to the field of thermal insulation material mixing and stirring technology, and in particular to a high-efficiency thermal insulation material mixing and stirring device. Background Technology

[0002] In the production process of thermal insulation materials, various raw materials, such as insulation particles, binders, and additives, need to be thoroughly mixed and stirred to ensure the quality and performance of the final product.

[0003] Existing devices mostly use a single stirring paddle or blade design, which can only achieve material agitation in a local area and is difficult to form a cross-mixing flow field in all directions. They also lack a scraping structure that fits tightly against the tank wall, which causes viscous insulation material to easily adhere to the tank wall and form clumps, reducing the effective mixing volume. To address this, we propose a high-efficiency mixing and stirring device for insulation materials. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency mixing and stirring device for thermal insulation materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency mixing and stirring device for thermal insulation materials, comprising an outer tank and a mixing mechanism disposed therein, a feeding mechanism disposed above the outer tank, the mixing mechanism comprising a servo motor, the servo motor being connected to a sleeve via bolts and nuts, three sets of scraper frames being fixedly installed on the outer wall of the sleeve, and multiple sets of spiral blade frames being rotatably connected inside the three sets of scraper frames, the sleeve being connected to a mixing tank and a plug-in block via a fixed shaft.

[0006] As a preferred embodiment, the inner wall of the outer tank is provided with a fluid channel, and a sealing cover is inserted into the upper end of the outer tank. The surface of the sealing cover has a discharge groove penetrating on both sides near the center.

[0007] As a preferred embodiment, the servo motor is fixedly mounted on the upper surface of the sealing cover plate, the upper end of the sleeve is inserted into the outer wall of the output shaft of the servo motor, the bolt passes through the sleeve and the output shaft of the servo motor, and the nut is threaded onto the outer wall of the bolt.

[0008] As a preferred embodiment, the fixed shaft is fixedly installed at the center of the inside of the mixing tank, the sleeve is sleeved on the outer wall of the fixed shaft, the plug block is fixedly installed on the outer wall of the mixing tank, the mixing tank is slidably connected to the inside of the outer tank through the plug block, and the outer walls of the three sets of scraping frames abut against the inner wall of the mixing tank.

[0009] As a preferred embodiment, the feeding mechanism includes a dust feeding channel and a liquid feeding channel. The dust feeding channel is fixedly installed inside a set of feeding troughs, and a screening plate is fixedly installed on the inner wall of the dust feeding channel.

[0010] As a preferred embodiment, the liquid feeding channel is fixedly installed inside another set of feeding troughs. A dispersing plate is fixedly installed inside the liquid feeding channel. A feed pipe is fixedly installed on the side of the liquid feeding channel above the dispersing plate. A funnel is fixedly installed at the upper end of the feed pipe. A pressure plate is slidably connected inside the liquid feeding channel. An operating rod is fixedly installed at the upper end of the pressure plate. The operating rod is slidably connected to the liquid feeding channel.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set mixing mechanism, the servo motor drives the sleeve to rotate, which drives three sets of scraper frames and multiple sets of spiral blade frames to operate. The spiral blade frames can fully stir, tumble and push the insulation material to achieve rapid cross mixing of materials. The scraper frames abut against the inner wall of the mixing tank and can scrape off the material adhering to the tank wall in time during the rotation process to avoid material accumulation and ensure that all materials in the tank can participate in the mixing, which significantly improves the mixing uniformity and mixing efficiency. Compared with traditional stirring devices, the mixing time can be greatly shortened.

[0013] 2. Through the designed feeding mechanism, the dust feeding channel and the liquid feeding channel are separated to achieve independent conveying of powdered insulation material and liquid additives. This avoids premature contact between the two before they enter the mixing tank, prevents the powdered material from clumping, and ensures that materials of different forms can enter the mixing process in an ideal state. The screening plate in the dust feeding channel can screen the powdered material in real time, effectively removing any lumps, impurities, or large particles, ensuring that the powdered insulation material entering the mixing tank has a uniform particle size and reducing the problem of uneven mixing caused by differences in material particle size. The dispersing plate in the liquid feeding channel can disperse the liquid entering the channel into fine droplets, increasing the contact area between the liquid and the powdered material, allowing the liquid additives to be dispersed more quickly and evenly in the powdered material, significantly improving the mixing effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see the appendix Figure 1 - Appendix Figure 6 A high-efficiency mixing and stirring device for thermal insulation materials includes an outer tank 1 and a mixing mechanism 5 disposed inside it. A feeding mechanism 6 is disposed above the outer tank 1. The mixing mechanism 5 includes a servo motor 501. The servo motor 501 is connected to a sleeve 502 by bolts 503 and nuts 504. Three sets of scraper frames 508 are fixedly installed on the outer wall of the sleeve 502. Multiple sets of spiral blade frames 509 are rotatably connected inside the three sets of scraper frames 508. The sleeve 502 is connected to a mixing tank 505 and a plug block 506 by a fixed shaft 507.

[0026] The inner wall of the outer tank 1 is provided with a fluid channel 2, and a sealing cover plate 3 is inserted into the upper end of the outer tank 1. The surface of the sealing cover plate 3 has a feeding groove 4 through it on both sides near the center.

[0027] The fluid channel 2 opened on the inner wall of the outer tank 1 can be used to introduce heating or cooling fluid according to process requirements, so as to control the temperature of the material inside the tank and meet the special temperature requirements of different insulation materials during mixing. The sealing cover plate 3 at the upper end of the outer tank 1, together with the feeding trough 4, not only ensures the sealing of the device and prevents material leakage and dust from flying, but also facilitates the addition of materials, enabling continuous production and improving production efficiency.

[0028] Servo motor 501 is fixedly installed on the upper surface of sealing cover plate 3. The upper end of sleeve 502 is inserted into the outer wall of the output shaft of servo motor 501. Bolt 503 passes through sleeve 502 and the output shaft of servo motor 501. Nut 504 is threadedly connected to the outer wall of bolt 503.

[0029] The servo motor 501 is connected to the sleeve 502 by bolts 503 and nuts 504. This connection method not only ensures the stability of power transmission, enabling the servo motor 501 to reliably transmit power to the stirring component, but also facilitates disassembly. When the stirring component needs to be inspected, cleaned, or replaced, the bolts 503 and nuts 504 can be quickly unscrewed to disassemble the sleeve 502 and related components, reducing maintenance difficulty, improving equipment maintenance efficiency, and reducing downtime.

[0030] The fixed shaft 507 is fixedly installed at the center of the inside of the mixing tank 505. The sleeve 502 is sleeved on the outer wall of the fixed shaft 507. The plug block 506 is fixedly installed on the outer wall of the mixing tank 505. The mixing tank 505 is slidably connected to the inside of the outer tank 1 through the plug block 506. The outer walls of the three sets of scraper frames 508 abut against the inner wall of the mixing tank 505.

[0031] The mixing tank 505 is slidably connected to the inside of the outer tank 1 via the plug-in block 506. The cooperation between the fixed shaft 507 and the sleeve 502 makes the mixing tank 505 securely installed and able to rotate flexibly. This design facilitates the installation and disassembly of the mixing tank 505, while ensuring that the mixing tank 505 runs smoothly during the mixing process, reducing noise and equipment wear caused by shaking, and extending the service life of the equipment.

[0032] Specifically, the servo motor 501 drives the sleeve 502 to rotate, which in turn drives the three sets of scraper frames 508 and multiple sets of spiral blade frames 509 to operate. The spiral blade frames 509 can fully stir, tumble and push the insulation material to achieve rapid cross-mixing of materials. The scraper frames 508 abut against the inner wall of the mixing tank 505. During the rotation, they can scrape off the material adhering to the tank wall in time to avoid material accumulation and ensure that all materials in the tank can participate in the mixing, which significantly improves the mixing uniformity and mixing efficiency. Compared with traditional stirring devices, the mixing time can be greatly shortened.

[0033] Please see the appendix Figure 1 and attached Figure 7 - Appendix Figure 9 The feeding mechanism 6 includes a dust feeding channel 601 and a liquid feeding channel 603. The dust feeding channel 601 is fixedly installed inside a set of feeding troughs 4, and a screening plate 602 is fixedly installed on the inner wall of the dust feeding channel 601.

[0034] A liquid discharge channel 603 is fixedly installed inside another set of discharge troughs 4. A dispersing plate 606 is fixedly installed inside the liquid discharge channel 603. A feed pipe 604 is fixedly installed on the side of the liquid discharge channel 603 above the dispersing plate 606. A funnel 605 is fixedly installed at the upper end of the feed pipe 604. A pressure plate 607 is slidably connected inside the liquid discharge channel 603. An operating rod 608 is fixedly installed at the upper end of the pressure plate 607. The operating rod 608 is slidably connected to the liquid discharge channel 603.

[0035] The pressure plate 607, which is slidably connected inside the liquid feeding channel 603, works in conjunction with the operating lever 608 to flexibly control the liquid feeding speed according to actual production needs.

[0036] Specifically, the dust feeding channel 601 and the liquid feeding channel 603 enable independent conveying of powdered insulation material and liquid additives, preventing them from coming into contact before entering the mixing tank 505, thus preventing the powdered material from clumping and ensuring that materials of different forms can enter the mixing process in an ideal state. The screening plate 602 in the dust feeding channel 601 can screen the powdered material in real time, effectively removing any lumps, impurities, or large particles that may be present, ensuring that the powdered insulation material entering the mixing tank 505 has a uniform particle size and reducing the problem of uneven mixing caused by differences in material particle size. The dispersing plate 606 in the liquid feeding channel 603 can disperse the liquid entering the channel into fine droplets, increasing the contact area between the liquid and the powdered material, so that the liquid additive can be dispersed more quickly and evenly in the powdered material, significantly improving the mixing effect.

[0037] Working principle of this utility model: This utility model is a high-efficiency mixing and stirring device for thermal insulation materials. First, the servo motor 501 is started. The servo motor 501 drives the sleeve 502 to rotate through the bolt 503 and the nut 504.

[0038] Powdered thermal insulation material is poured into the device through the dust discharge channel 601. The screening plate 602 in the dust discharge channel 601 screens the powdered material in real time, and removes lumps, impurities or large particles. The qualified material falls into the mixing tank 505 through the discharge trough 4.

[0039] The liquid additive enters the liquid discharge channel 603 through the funnel 605 and the feed pipe 604. The liquid is broken into fine droplets by the dispersing plate 606 in the channel. The position of the pressure plate 607 is controlled by the operating rod 608 to adjust the discharge speed and amount of the liquid additive, so that it falls into the mixing tank 505 through another set of discharge troughs 4.

[0040] The servo motor 501 is started, which drives the sleeve 502 to rotate. When the sleeve 502 rotates, the three sets of scraper frames 508 on the outer wall rotate accordingly. The multiple sets of spiral blade frames 509 inside the scraper frame 508 agitate, tumble and push the material in the mixing tank 505. At the same time, the outer wall of the scraper frame 508 abuts against the inner wall of the mixing tank 505, scraping off the material adhering to the tank wall to ensure that the material is fully mixed.

[0041] According to process requirements, heating or cooling fluid can be introduced through the fluid channel 2 on the inner wall of the outer tank 1 to adjust the temperature of the material in the mixing tank 505, so as to meet the temperature requirements of different insulation materials during the mixing process.

[0042] After mixing is complete, open the sealing cover 3, remove the mixing tank 505 from the outer tank 1, and pour out the mixed insulation material.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
