Description

Technical Field

[0001] This utility model relates to the technical field of flame retardant production equipment, and in particular to a raw material mixing equipment for flame retardant preparation. Background Technology

[0002] In the production and preparation process of flame retardants, the uniformity of raw material mixing directly affects the final performance of the flame retardant, and the mixing equipment, as the core production device, has a mixing efficiency and effect that is crucial to the production quality.

[0003] The prior art discloses a mixing device for the production of environmentally friendly flame retardants, with application number 202420942771.1. The device includes a mixing cylinder, a storage cylinder, a motor, and a sealing assembly. Two storage cylinders are fixedly connected to the top of the mixing cylinder. Feeding pipes are fixedly connected inside each of the two storage cylinders, with their bottom ends extending into the mixing cylinder. Valves are installed inside each of the feeding pipes. Rotary plates are rotatably connected to the top of each of the two storage cylinders. This invention, through the coordinated use of the storage cylinders, feeding pipes, valves, and rotating plates, allows for simultaneous feeding of materials into the mixing cylinder via the two feeding pipes, improving the mixing efficiency. The coordinated use of the motor, rotating shaft, frame, stirring blades, mixing blades, connecting rod, and scraper accelerates the mixing process and also scrapes off raw materials adhering to the inner wall of the mixing cylinder, facilitating subsequent cleaning by workers. However, existing technologies still rely on direct feeding through the feed pipe, lacking the ability to crush and filter agglomerated raw materials, which can easily lead to particle agglomeration during the mixing process. Therefore, we propose a raw material mixing device for flame retardant preparation to solve the above problems. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a raw material mixing device for flame retardant preparation. By adding a filter screen and a liquid inlet triangular prism-shaped crushing and stirring blade, it can pre-crush and filter agglomerated raw materials, avoiding particle agglomeration that affects the uniformity of mixing. At the same time, the multi-stage mixing structure improves the mixing efficiency and is suitable for the stringent requirements for raw material dispersibility in flame retardant production.

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0006] A raw material mixing device for flame retardant preparation includes a mixing tank, a tank cover, a platform, and a storage cylinder. The mixing tank consists of an inner tank and an outer tank. The outer tank is fixedly installed on the upper surface of the platform. Support legs are fixedly connected to the four corners of the lower surface of the platform. A heating element is fixedly installed between the inner tank and the outer tank. The storage cylinder is installed on the upper part of the tank cover. A feeding pipe penetrating the tank cover is connected to the lower end of the storage cylinder. A filter screen groove is installed below the tank cover, and a liquid inlet valve is installed inside the filter screen groove. The liquid inlet triangular prism-shaped crushing and agitating blade has a diameter smaller than the inner diameter of the filter screen groove. A motor is fixedly installed at the upper center of the box cover, and the output end of the motor is fixedly connected to a connecting rod. The liquid inlet triangular prism-shaped crushing and agitating blade is fixedly installed at the lower end of the connecting rod. A push rod mounting plate is fixedly welded to the outer wall of the outer box. A lifting push rod is installed at the upper end of the push rod mounting plate, and the output end of the lifting push rod is fixedly connected to the connecting plate. The connecting plate and the box cover are integrally formed.

[0007] Furthermore, a mixing electrode is fixedly installed at the lower center of the platform, and the output end of the mixing electrode is fixedly connected to the transmission rod. The transmission rod passes through the bottom of the platform and the mixing box and extends into the inner box. Several first mixing blades are fixedly connected to the outer wall of the transmission rod, and connecting vertical plates are symmetrically fixedly connected to both sides of the top end of the transmission rod.

[0008] Furthermore, a second mixing blade is fixedly connected to the outer wall of the connecting vertical plate, and the second mixing blade is staggered with the first mixing blade.

[0009] Furthermore, connecting horizontal plates are fixedly connected to the upper and lower ends of the connecting vertical plate, and scrapers are fixedly connected to the ends of the connecting horizontal plates.

[0010] Furthermore, the scraper is fitted to the inner wall of the inner box, and the scraper is made of wear-resistant rubber, with several strip-shaped through holes on its surface.

[0011] Furthermore, a discharge valve is connected to one side of the bottom of the inner box, and the output end of the discharge valve is connected to a discharge pipe.

[0012] Furthermore, the heating element is an annular heating tube, and the heating elements are evenly distributed on the outer wall of the inner box.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. Integrated pre-crushing and filtration to solve agglomeration problem: After the raw material enters the filter screen tank through the feeding pipe, the liquid inlet triangular prism crushing and stirring blades mechanically crush the agglomerated raw material. At the same time, the stainless steel filter screen in the filter screen tank intercepts large uncrushed particles, ensuring that the raw material entering the inner box has a uniform particle size and avoiding particle agglomeration during the mixing process from the source.

[0015] 2. Multi-stage mixing enhances uniformity: The first and second mixing blades are staggered to form a three-dimensional mixing space. With the help of the connecting vertical plate, the scraper rotates. This reduces the mixing resistance through the strip-shaped through-holes and scrapes off the raw materials adhering to the inner wall of the inner box, realizing a cycle of "mixing-scraping-remixing", which greatly improves the mixing uniformity of the flame retardant raw materials.

[0016] 3. Convenient operation and strong adaptability: The lifting push rod drives the lid to rise and fall, facilitating the cleaning of the filter tray and replacement of the filter screen; the annular heating tubes are evenly distributed on the outer wall of the inner chamber, and the heating temperature can be adjusted according to the characteristics of the flame retardant raw materials to avoid local overheating affecting the performance of the raw materials. It is suitable for flame retardant mixing scenarios containing heat-sensitive components.

[0017] In summary, the raw material mixing equipment for the preparation of this flame retardant has wide applicability, which solves the problem mentioned in the background art that the existing technology still has the problem of direct feeding through the feeding pipe, lack of crushing and filtering of agglomerated raw materials, and easy to cause particle agglomeration during the mixing process.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0022] like Figure 1As shown, the embodiment of this utility model includes a mixing box 1, a box cover 2, a platform 3, and a storage cylinder 5. The mixing box 1 consists of an inner box 101 and an outer box 102. The outer box 102 is fixedly installed on the upper surface of the platform 3. Support legs 4 are fixedly connected to the four corners of the lower surface of the platform 3. A heating element 22 is fixedly installed between the inner box 101 and the outer box 102. The storage cylinder 5 is installed on the upper end of the box cover 2. The lower end of the storage cylinder 5 is connected to a feeding pipe 6 that penetrates the box cover 2. A filter screen groove 7 is installed below the box cover 2. A liquid inlet triangular prism-shaped crushing and stirring blade 10 is installed inside the filter screen groove 7. The diameter of the liquid inlet triangular prism-shaped crushing and stirring blade 10 is smaller than the inner diameter of the filter screen groove 7. A motor 8 is fixedly installed in the middle of the upper end of the box cover 2. The output end of the motor 8 is fixedly connected to a connecting rod 9. The liquid inlet triangular prism-shaped crushing and stirring blade 10 is fixedly installed at the lower end of the connecting rod 9. A push rod mounting plate 11 is fixedly welded to the outer wall of the outer casing 102. A lifting push rod 12 is installed at the upper end of the push rod mounting plate 11. The output end of the lifting push rod 12 is fixedly connected to the connecting plate 13. The connecting plate 13 and the casing cover 2 are integrally formed.

[0023] A mixing motor 15 is fixedly installed at the lower center of the platform 3. The output end of the mixing motor 15 is fixedly connected to the transmission rod 16. The transmission rod 16 passes through the bottom of the platform 3 and the mixing box 1 and extends into the inner box 101. Several first mixing blades 17 are fixedly connected to the outer wall of the transmission rod 16, and connecting vertical plates 18 are symmetrically fixedly connected to both sides of the top of the transmission rod 16. Second mixing blades 19 are fixedly connected to the outer wall of the connecting vertical plates 18, and the second mixing blades 19 are staggered with the first mixing blades 17. Connecting horizontal plates 20 are fixedly connected to the upper and lower ends of the connecting vertical plates 18, and scrapers 21 are fixedly connected to the ends of the connecting horizontal plates 20. The scrapers 21 are in contact with the inner wall of the inner box 101, and the scraper 21 is made of wear-resistant rubber. Several strip-shaped through holes are opened on the surface of the scraper 21. A discharge valve 23 is connected to one side of the bottom of the inner box 101, and the output end of the discharge valve 23 is connected to a discharge port 14. The heating element 22 is an annular heating tube, and the heating elements 22 are evenly distributed on the outer wall of the inner box 101.

[0024] This equipment has significant advantages in the mixing of flame retardant raw materials. From the perspective of raw material pretreatment, the storage cylinder 5 conveys the raw materials to the filter screen tank 7 through the feeding pipe 6. The motor 8 drives the connecting rod 9 to rotate the liquid inlet triangular prism crushing and stirring blade 10, which can perform preliminary crushing and stirring of the raw materials. The filter screen tank 7 can filter out large particle impurities, ensuring that the raw material entering the inner box 101 has a more uniform particle size, laying a good foundation for subsequent mixing.

[0025] In terms of mixing effect, the mixing motor 15 drives the transmission rod 16 to rotate, causing the first mixing blade 17 and the second mixing blade 19 on the connecting vertical plate 18 to rotate synchronously. The staggered arrangement of the two blades enables multi-directional and thorough mixing of the raw materials, significantly improving the mixing uniformity. Simultaneously, the scraper 21 at the end of the connecting horizontal plate 20 is in contact with the inner wall of the inner box 101. During rotation, it scrapes off the raw materials adhering to the inner wall, preventing waste caused by residue. The strip-shaped through holes on the surface of the scraper 21 reduce resistance during scraping, making the mixing process smoother. The wear-resistant rubber material of the scraper 21 also prevents scratching the inner wall of the inner box 101, extending the service life of the equipment.

[0026] In terms of heating function, the annular heating tube and the evenly distributed heating element 22 can uniformly heat the inner box 101. The temperature can be adjusted according to the needs of flame retardant preparation, promote the reaction between raw materials, and improve mixing efficiency and quality.

[0027] In terms of ease of operation, the lifting push rod 12 can drive the box cover 2 to rise and fall, making it convenient to clean and maintain the inside of the mixing box 1; the setting of the discharge valve 23 and the discharge port 14 facilitates the discharge of raw materials after mixing, making the overall operation simple and efficient.

[0028] All electrical components mentioned in the text are electrically connected to an external controller and power supply, and the controller can be a conventional known device such as a computer that provides control.
