Description

Technical Field

[0001] The utility model relates to the technical field of granulator accessories, in particular to a special rubber granulation rubber plate for chemical industry. Background Art

[0002] In the chemical production process, the granulator is an important production equipment, which is used to convert liquid or semi-solid chemical raw materials into granules to realize granulation operation. The inside of the granulator is equipped with a rubber granulation rubber plate, which is installed on the inner wall of the cylinder of the granulator to protect the inner wall of the cylinder of the granulator from the influence of acid and alkali materials such as fertilizer particles. At the same time, the rubber granulation rubber plate also provides wear resistance and impact resistance, so as to extend the service life of the granulator.

[0003] There are many types of granulation rubber sheets on the market. The surface of granulation rubber sheets is generally provided with protrusions. The existence of protrusions is conducive to reducing the adhesion of raw materials. Most granulation rubber sheets are fixed on the inner wall of the granulator by fastening screws. However, when fastening screws are used for fixing, the fastening screws occupy space at the fixing part, which will cause the lack of protrusions at this part. Without protrusions, the surface of this part will be flatter, and particles are prone to adhere to this part, which brings inconvenience to users. In view of this, we propose a special rubber granulation rubber sheet for chemical industry. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a rubber granulation rubber sheet for chemical industry, including a rubber sheet body 1, the rubber sheet body 1 can be made of polyurethane rubber material, the polyurethane rubber material has good acid and alkali resistance and wear resistance, is suitable for chemical industry, and can achieve the effect of being able to be used in chemical industry;

[0027] Specifically, the surface of the rubber sheet body 1 is provided with a plurality of wear-resistant protrusions 13 arranged in a matrix. Through the provided wear-resistant protrusions 13, after the particles fall onto the wear-resistant protrusions 13, the contact area with the wear-resistant protrusions 13 is smaller. The smaller contact area can reduce the adsorption force between the wear-resistant protrusions 13 and the particles, making it difficult for the particles to be adsorbed on the rubber sheet body 1, which is conducive to the particles falling down;

[0028] Specifically, screw holes 2 are provided at the four corners of the rubber plate body 1, and hard support sleeves 20 are fixedly installed on the upper surfaces of the four corners of the rubber plate body 1. The hard support sleeves 20 are concentrically arranged with the corresponding screw holes 2, and a corner support protrusion 3 is provided on the hard support sleeve 20. A center hole 31 connected to the outside is provided at the center position of the corner support protrusion 3. The center hole 31 is connected to the screw hole 2 and is used for screw insertion and fixing operations, so that the corner support protrusion 3 can continue to protect the fastening screw part from particle adsorption while using the fastening screw to fix it, which is beneficial for the particles to fall down.

[0029] In this embodiment, a reinforcement ring 30 is fixedly installed at the bottom of the corner support protrusion 3. The reinforcement ring 30 is fixedly installed on the upper surface of the rubber plate body 1 to increase the contact area, making it more firmly and stably fixed on the rubber plate body 1 and less likely to fall off.

[0030] Specifically, a hollow chamber 10 is provided inside the rubber plate body 1, and a plurality of hollow buffer rubber balls 11 arranged in a matrix are fixedly installed between the upper and lower cavity walls of the hollow chamber 10, and the hollow buffer rubber balls 11 are used for buffering protection operations; the hollow buffer rubber balls 11 are hollow spherical and are used for buffering protection.

[0031] Furthermore, a plurality of bottom support steel wires 12 arranged linearly and equidistantly are provided in the bottom plate body of the rubber plate main body 1, and the bottom support steel wires 12 are used for pulling and protecting operations; the bottom support steel wires 12 and the rubber plate main body 1 are an integrally formed structure for stabilizing the overall structure.

[0032] In addition, a surface wear-resistant layer 14 is provided on the surface of the rubber plate body 1. The surface wear-resistant layer 14 can be made of wear-resistant paint to improve wear resistance. The surface wear-resistant layer 14 is used for wear-resistant protection operation.

[0033] It is worth noting that mirror-smooth layers 15 are provided on the four sides of the rubber plate body 1. The mirror-smooth layers 15 are used for bonding operations so that when multiple rubber plate bodies 1 are assembled together, the side parts of the rubber plate bodies 1 can be better bonded together.

[0034] When the chemical special rubber granulation rubber sheet of the utility model is used, the rubber sheet body 1 is attached to the inner wall of the granulator, and then the screws are passed through the center hole 31 and the screw holes 2 and fixed to the inner wall of the rubber sheet body 1, ensuring that the cap head of the fastening screw is against the hard support sleeve 20 and the center hole 31 is blocked at the same time, completing the fixing operation.
