Description

Technical Field

[0001] This utility model relates to a dust prevention and cleaning device for a crusher, belonging to the technical field of crusher cleaning equipment. Background Technology

[0002] Crushers are commonly used equipment in chemical, pharmaceutical, and food processing industries. After use, material powder or sticky substances easily remain in the inner cavity of the crusher. Traditional cleaning methods include contact cleaning and non-contact cleaning. Contact cleaning includes manual brushing, water washing, and solvent rinsing. Contact cleaning can easily damage the inner cavity surface, such as blades and screens, resulting in high equipment wear and tear. Manual brushing is inefficient and affects continuous production. Water washing or solvent rinsing poses a risk of cross-contamination and may introduce secondary pollution, such as microorganisms and solvent residues. Solvent cleaning requires waste liquid treatment, increasing costs. Non-contact cleaning uses compressed air cleaning technology, which has advantages such as avoiding physical wear, leaving no liquid residue, and rapid drying. However, it easily generates dust during the cleaning process, which not only pollutes the environment and affects human health, but also poses a significant safety hazard as the dust from metals or organic materials may explode.

[0027] 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 scope of protection of the present utility model.

[0028] like Figures 1-4 As shown, the first embodiment of this utility model provides a dustproof and cleaning device for a crusher, including a crusher body 1, a dust cover 2 provided at the entrance of the crusher body 1, a transparent baffle 3 rotatably connected to the dust cover 2, and a through hole 4 for inserting an air compressor pipe on the transparent baffle 3.

[0029] The dust cover 2 is a 3D-printed optimized dust cover that is adapted to the entrance of the pulverizer cavity. The end of the dust cover near the entrance of the cavity is provided with a quick-release interface for easy disassembly and assembly, and the end away from the entrance of the cavity is rotatably connected to the transparent baffle 3 through a rotating connection structure 7.

[0030] The quick-release interface is a flange structure that is the same as or similar to the structure of the crusher body cavity entrance. A magnetic button 5 is embedded within the flange structure, allowing the dust cover 2 to be quickly and magnetically fixed to the crusher body 1 cavity entrance. Furthermore, a printed flexible lip (TPU material) or a pre-reserved silicone sealing groove is provided at the edge of the quick-release interface, with a sealing ring 6 installed within the sealing groove to enhance fit and sealing, preventing dust leakage.

[0031] The dust cover 2 is no less than 5 cm high to ensure working space when the compressed air hose is inserted for cleaning.

[0032] The dust cover 2 can be made of metal or polymer plastic. Metal dust covers can be made of stainless steel 316L, lightweight aluminum alloy, etc., suitable for explosion-proof environments. Polymer plastic dust covers can be made of nylon 12, PC, etc.

[0033] The transparent baffle 3 includes an inner baffle ring 301 and a transparent plate 302 disposed in the middle of the inner baffle ring. The transparent plate 302 can be a transparent PC board or plexiglass. The thickness of the transparent plate 302 is 2-3mm, and its transparency is sufficient to observe the internal cleanliness during air compressor pipe cleaning operations.

[0034] The rotating connection structure 7 is similar to the existing bearing structure. Specifically, the rotating connection structure 7 includes a first groove 701 on the inner wall of the dust cover 2 away from the entrance of the body cavity, a second groove 702 on the outer circumference of the inner retaining ring 301 opposite to the position of the first groove 701, and a ball bearing 703 between the two grooves. The ball bearing 703 is evenly distributed circumferentially by a retainer 704, so that the transparent baffle 3 is rotatably connected to the dust cover 2 by the ball bearing 703 and fixed by an end cap 705 on the outside of the dust cover 2.

[0035] A sealing groove 706 is provided on one or both sides of the first groove 701 of the dust cover, and a sealing ring 8 is provided in the sealing groove 706.

[0037] (1) When the crusher body 1 needs to be cleaned, open the cavity door of the crusher body 1 and magnetically fix the dust cover 2 to the cavity door of the crusher body 1;

[0038] (2) The air pipe of the air compressor is inserted through the through hole 4 on the transparent baffle 3 to carry out the cleaning operation. During the operation, the air pipe rotates with the transparent baffle 3 to achieve all-round cleaning inside the pulverizer body 1. It can accelerate the discharge of dust from the cone-shaped discharge port at the bottom of the pulverizer body 1 by using gravity and airflow. The cleaning efficiency is high, and dust can be effectively avoided during the cleaning process.
