Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a low-noise crusher with a housing structure. Background Technique

[0002] As a device widely used in industries such as mining, construction, metallurgy, and environmental protection, crushers are mainly used to crush and pulverize materials to meet production requirements.

[0003] Traditional crushers generally achieve crushing by the impact of high-speed rotating hammers or blades on materials. During their operation, a large amount of noise and vibration are generated, seriously affecting the health of operators and the working environment. Therefore, controlling the noise pollution of crushers and improving the comfort of their working environment have become problems to be solved in the industry. For example, currently:

[0004] 1. To reduce the noise of crushers, the industry usually adopts the method of installing a sound insulation cover outside the crusher or setting up a sound insulation room to try to reduce noise leakage. However, such sound insulation structures often have problems such as large volume, poor sealing, and unsatisfactory sound insulation effect. In addition, the installation and maintenance of the sound insulation cover are complex, resulting in a bulky overall structure of the equipment and inconvenient operation. Moreover, improper selection of the sound insulation cover material may also lead to poor heat dissipation of the equipment, causing potential safety hazards.

[0005] 2. To optimize the feeding path, simple feeding funnels and guide plates are generally used in the prior art. However, due to unreasonable structural design, material accumulation and jamming are likely to occur, thus affecting the crushing efficiency. Some improved designs add inclined planes in the funnel pipe to guide materials. However, due to insufficient optimization of the feeding path, the materials are prone to deviation during the falling process, resulting in uneven feeding and ultimately affecting the crushing effect.

[0006] To solve these problems, some equipment introduces multi-layer sound insulation materials and guiding designs. However, these improvements still have problems such as improper selection of sound insulation materials, poor guiding effect, and low feeding efficiency, and it is difficult to fundamentally improve the performance of the equipment.

[0007] Therefore, how to reduce the noise of crushers, optimize the feeding path, improve the operation efficiency of the equipment and the comfort of the working environment has become the technical problem to be solved by the utility model. Content of the Utility Model

[0008] The technical problem solved by the utility model is to provide a low-noise crusher with a housing structure to solve the problems of large noise, uneven feeding, inconvenient operation and maintenance of crushers as mentioned in the above background technique in view of the defects existing in the above prior art.

[0009] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0015] The crusher body is located inside the sound-absorbing box housing. The sound-absorbing box housing includes a door body, and a feed avoiding hole matching with the horizontal feed guiding pipe is provided on the door body.

[0016] As a further solution of the present utility model, the door body is a double-opening door body, and the feed avoiding hole is formed by a combination of half holes provided on two double-opening door bodies.

[0017] As a further solution of the present utility model, the funnel pipe, the horizontal pipe box, and the horizontal feed guiding pipe are of an integral structure.

[0018] As a further solution of the present utility model, four support columns for supporting the sound-absorbing box housing are evenly distributed at the bottom of the sound-absorbing box housing.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] 1.

[0036] Embodiment 1:

[0037] In practical applications, the raw material processing workshop of a certain factory needs to crush a large amount of ore and construction waste. This crushing process is accompanied by extremely high noise and vibration, seriously affecting the comfort of the working environment and having an adverse impact on the health of the operators. The simple sound insulation covers used in traditional crushers cannot effectively control noise, and due to the vibration of the equipment, material accumulation and blockage often occur during the feeding process, affecting production efficiency. To solve these problems, the factory introduced the low-noise crusher with a housing structure of the present utility model.

[0038] In this application scenario, the crusher of this embodiment includes a crusher body 1, a funnel pipe 3, a horizontal pipe box 4, a horizontal feeding guide pipe 5 and a door body 6, and the crusher body 1 is arranged in a soundproof chamber 9. The inner wall of the soundproof chamber 9 is covered with polyester fiber sound-absorbing boards. Through the porous structure and high sound-absorbing performance of this sound-absorbing material, most of the high-frequency noise generated during the operation of the crusher is effectively absorbed. At the same time, the soundproof chamber 9 provides physical protection for the crusher body 1, avoiding the erosion of dust and moisture in the external environment on the equipment, and significantly extending the service life of the crusher.

[0039] During the feeding process, the ore enters the horizontal pipe box 4 through the funnel pipe 3 provided with a vertical first inclined surface 7. The designed vertical inclined surface effectively guides the material to fall smoothly, avoiding the material accumulation problem common in traditional funnels. Subsequently, the material enters the horizontal feeding guide pipe 5 provided with a horizontal second inclined surface 8. This horizontal inclined surface further evenly guides the material to the crusher feeding port 2, ensuring uniform and stable feeding, and overcoming the problem of poor crushing effect caused by uneven feeding in the prior art.

[0040] Through the above structural design, the double-inclined surface guidance adopted in this embodiment not only realizes continuous and efficient feeding of materials, but also avoids blockage and unevenness in the feeding link of traditional crushers, significantly improving the working efficiency of the equipment. In addition, since the crusher body 1 is enclosed in the soundproof chamber 9, the noise during the crushing process is almost completely isolated, greatly improving the operation environment of the factory, effectively controlling noise pollution, and significantly improving the working comfort and safety of the operators.

[0041] The door body 6 is designed as a double-door structure, and a feeding avoidance hole 11 is provided on the door body 6, so that workers do not need to frequently open the soundproof chamber 9 during the feeding process, which not only reduces the leakage of noise, but also improves the convenience and safety of operation. The design of the entire soundproof chamber 9 not only has better sound insulation effect than traditional sound insulation covers, but also simplifies the daily maintenance and cleaning work of the equipment.
