Description

Technical Field

[0001] The utility model relates to the technical field of particle cooling equipment, in particular to a hemispherical particle cooling and forming equipment. Background Art

[0002] Antistatic particles are a commonly used functional additive in the field of organic polymers. For example, adding antistatic particles during PE processing can give PE plastics better antistatic properties. Therefore, antistatic particles are often melted and added to product raw materials in the form of particles when used. This requires that when producing antistatic particles, the antistatic particles should be produced as granular substances with relatively consistent shapes.

[0003] The Chinese utility model patent with authorization announcement number CN202911051U discloses a cooling device for an antistatic particle production line, including an aluminum alloy conveyor belt with a water cooling device and an antistatic particle production machine. The feeding end of the aluminum alloy conveyor belt extends into the antistatic particle production machine, and an air-cooling bracket is placed around the aluminum alloy conveyor belt. The air-cooling channel cover is buckled on the air-cooling bracket and covers the surface of the aluminum alloy conveyor belt; the air supply duct of the refrigeration unit is connected to the air-cooling channel cover corresponding to the antistatic particle production machine, and the air inlet duct of the refrigeration unit is connected to the air-cooling channel cover corresponding to the discharge port of the aluminum alloy conveyor belt.

[0004] However, when the above-mentioned cooling device cools the antistatic particles, the air cooling equipment blows air on the particles being cooled and formed, which causes irregular dents and ripples to appear on the surface of the particles, thereby affecting the shape uniformity of the final particle product. Therefore, it is urgent to provide a solution to improve this problem. Utility Model Content

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0019] See also Figures 1 to 3 The embodiment of the utility model provides a hemispherical particle cooling and forming device, including a frame 1, a cooling conveyor belt 2 is rotatably arranged on the frame 1, and a driving device for driving the cooling conveyor belt 2 to rotate and convey. Specifically, the cooling conveyor belt 2 is made of stainless steel, and the stainless steel material can be used to cool the product, and the driving device can specifically be a rotating motor.

[0020] In fact, the starting end of the conveying direction of the cooling conveyor belt 2 itself is located at the unloading end of the liquid product production machine 12. When the liquid product production machine 12 is discharging, the liquid product will drip onto the cooling conveyor belt 2. Thus, under the cooling effect of the cooling conveyor belt 2, the product in the form of droplets will gradually form into a hemispherical granular product.

[0021] Specifically, the frame 1 is provided with a cooling trough 4 on a side of the cooling conveyor belt 2 relatively far from the liquid product production machine 12, and a plurality of guide pressing wheels 5 are rotatably provided at the opening of the cooling trough 4 and in the cooling trough 4, and the guide pressing wheels 5 are used to guide the cooling conveyor belt 2 into the cooling trough 4. Specifically, the guide pressing wheels 5 are rotatably provided on the side wall of the cooling trough 4, and the guide pressing wheels 5 are rotatably pressed against the side of the cooling conveyor belt 2, thereby preventing the guide pressing wheels 5 from rolling over the cooling product in the middle of the cooling conveyor belt 2.

[0022] Specifically, the cooling tank 4 contains a cooling liquid, and the cooling conveyor belt 2 passes through the cooling tank 4 and is partially immersed in the cooling liquid. The cooling liquid is used to cool the products to be cooled on the cooling conveyor belt 2 entering the cooling tank 4, and the cooling liquid also has a flushing and suspension effect, which can make the products adhered to the surface of the cooling conveyor belt 2 fall off. More specifically, the cooling liquid can be water.

[0023] In some embodiments, the frame 1 is further provided with a cooling circulation device at the cooling tank 4, and the cooling circulation device is used to connect the cooling tank 4 with an external liquid storage container and circulate the coolant externally. By using the cooling circulation device, the temperature of the coolant in the cooling tank 4 can be kept stable, thereby improving the continuous cooling effect of the coolant on the material.

[0024] In some embodiments, a scraper plate 6 is provided at the top of the cooling trough 4 on the frame 1, and the scraper plate 6 is located at the end side of the cooling trough 4 along the conveying direction of the cooling conveyor belt 2, and the scraper plate 6 is in sliding contact with the upper surface of the cooling conveyor belt 2, so that when the cooling conveyor belt 2 passes through the coolant, the scraper plate 6 can scrape off the product particles still adhering to the upper surface of the cooling conveyor belt 2.

[0025] In fact, see Figures 1 to 3 A scraper bevel 7 is provided on the side where the scraper plate 6 slides against the cooling conveyor belt 2, and the scraper plate 6 slides against the cooling conveyor belt 2 on the side located at the scraper bevel 7. The scraper plate 6 can increase its contact area with the cooling conveyor belt 2 through the scraper bevel 7, thereby being more conducive to scraping off product particles adhering to the surface of the cooling conveyor belt 2.

[0026] In some embodiments, see Figures 1 to 3 The frame 1 is located on the side of the cooling trough 4 relatively away from the liquid product production machine 12 and is rotatably provided with multiple drying rollers 8, and the multiple drying rollers 8 are all located on one side of the scraper plate 6 along the conveying direction of the cooling conveyor belt 2, and the multiple drying rollers 8 are all in rotational conflict with the surface of the cooling conveyor belt 2, so that the surface of the cooling conveyor belt 2 can be dried.

[0027] Specifically, the drying roller 8 may have a built-in electric heating wire, which generates heat to dry the surface of the cooling conveyor belt 2. In addition, the drying roller 8 may be wrapped with absorbent products such as absorbent cotton to absorb moisture from the surface of the cooling conveyor belt 2. In fact, multiple drying rollers 8 may use different drying methods, as long as the surface of the cooling conveyor belt 2 can be dried.

[0028] In some embodiments, a plurality of drying rollers 8 are symmetrically arranged on the upper and lower sides of the cooling conveyor belt 2 , so that the moisture on the upper and lower sides of the cooling conveyor belt 2 can be dried.

[0029] In some embodiments, see Figures 1 to 3The portion of the cooling conveyor belt 2 immersed in the coolant is in sliding contact with the inner wall of the cooling tank 4, and a temporary storage space 9 is formed between the portion of the cooling conveyor belt 2 immersed in the coolant and the inner wall of the cooling tank 4. The temporary storage space 9 is used to store the product particles scraped off by the scraper plate 6 and the cooling conveyor belt 2. In fact, since both sides of the cooling conveyor belt 2 are in sliding contact with the inner wall of the cooling tank 4, the product particles are prevented from escaping from the gap, and the product particles can also be concentrated in this area, which is conducive to collecting the product particles.

[0030] Specifically, the cooling trough 4 is located at the temporary storage space 9 and is rotatably provided with a filter rack 10, and the filter rack 10 is cross-shaped, and the filter rack 10 can be rotated on the cooling trough 4 along the conveying direction of the cooling conveyor belt 2, and a filter screen 11 is provided on the filter rack 10, and the filter screen 11 is used to scoop the formed product particles, thereby facilitating the rapid collection of the product particles concentrated in the temporary storage space 9. Specifically, the depth of the filter rack 10 into the cooling trough 4 must be sufficient not to interfere with the movement of the cooling conveyor belt 2.

[0031] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
