Description

Technical Field

[0001] This utility model relates to the field of crusher equipment technology, and more specifically, to a dustproof structure for a hammer crusher. Background Technology

[0002] A hammer crusher is a device that uses high-speed rotating hammers to impact and crush materials.

[0003] In the crushing stage of slag resource utilization, the hammer crusher has become a very balanced and ideal choice due to its powerful "combined crushing" capacity, controllable finished product particle size, efficient metal dissociation effect, good adaptability to complex materials, and low operating cost. It can efficiently and economically process waste slag with complex composition and different properties into recycled aggregate with uniform particle size that meets the standards for resource utilization, while maximizing the recovery of valuable metals, perfectly matching the core goal of resource utilization to "turn waste into treasure".

[0004] In the existing technology, although there are some solutions for spraying water into the crusher to reduce dust, the water spraying points are often not set properly, and the water flow cannot effectively cover the key areas where dust escapes, resulting in poor dust suppression effect. In addition, the mud formed by the material mixing with water during crushing will adhere to the surface of the crushing components of the crusher, and a large amount of dust adhesion will affect the crushing efficiency of the crusher.

[0005] Therefore, there is an urgent need for a dustproof structure for the shaft of a hammer crusher to solve the aforementioned problems in the existing technology. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dustproof structure for a hammer crusher to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dustproof structure for a hammer crusher, comprising a crusher, a feed hopper provided at the top of the crusher, a housing first provided at the top of the feed hopper, and a housing second provided at the bottom of the crusher;

[0008] A guide pipe is provided on the box body 1, a water inlet pipe is provided on one side of the guide pipe, and multiple branch pipes 1 for spraying water into the box body 1 are provided at the bottom of the guide pipe, and multiple branch pipes 2 for spraying water into the crusher are provided on one side of the guide pipe.

[0009] The second chamber is used to separate water and slurry from the crushed material.

[0010] In a preferred embodiment, the guide pipe is arranged around the outer wall of the housing, the end of the diversion pipe penetrates the housing and is provided with a nozzle, and the nozzles are evenly distributed on the inner wall of the housing.

[0011] In a preferred embodiment, the crusher is provided with a housing, and a rotating shaft for driving the crushing component is rotatably provided on the crusher. The crushing component is disposed inside the housing, and the end of the second diversion pipe penetrates the housing and is provided with a second nozzle, which is oriented toward the rotating shaft.

[0012] In a preferred embodiment, a sieve plate is provided inside the housing 2. The sieve plate is sloped, and a discharge port is provided on the lower side of the sieve plate.

[0013] In a preferred embodiment, a ball valve is provided at one end of the water inlet pipe.

[0014] In a preferred embodiment, a dust cover is provided on one side of the discharge port.

[0015] In a preferred embodiment, a sealing ring is fitted on the outer wall of the rotating shaft, and the sealing ring is disposed on the outer shell.

[0016] The technical effects and advantages of this utility model are as follows: Water is sprayed onto the material before it enters the crusher by uniformly arranged nozzles within the housing, effectively suppressing the initial dust diffusion. Second nozzles directly spray water onto the surface of the high-speed rotating crushing components, suppressing dust at its source and achieving more thorough dust control. Furthermore, the high-pressure nozzles continuously wash the surface of the crushing components, preventing the adhesion of wet dust and slurry, thus avoiding a decrease in crushing efficiency due to material adhesion and maintaining the cleanliness of the crushing components' working surface, thereby ensuring the continuous and efficient operation of the crusher. The inclined screen plate within the bottom housing effectively separates the crushed material from the water, facilitating subsequent material processing and recycling. Compared to existing technologies, this invention improves both dust control and production efficiency. Attached Figure Description

[0022] 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 protection scope of the present utility model.

[0023] Slag is typically a porous, dry, and brittle material. Under the impact of the high-speed hammers of a crusher, it easily generates a large amount of fine, highly mobile alkaline dust. These dust particles are not only visible to the naked eye but also cause serious pollution to the working environment and the surrounding air quality. Currently, some equipment attempts to directly spray water into the crushing chamber to reduce dust, but this approach often results in mud adhesion. The viscous mud formed by the combination of un-atomized water and dust firmly coats the crusher hammers and inner walls, forming a thick "armor." This not only greatly buffers the impact force of the hammers, significantly reducing crushing efficiency and throughput, but also leads to uneven equipment operating load, increased vibration, and even requires frequent shutdowns for manual cleaning, seriously affecting the continuity and economy of production.

[0024] As attached Figure 1 To be continued Figure 4 The dustproof structure of a hammer crusher shown includes a crusher 1, a feed hopper 101 at the top of the crusher 1, a housing 2 at the top of the feed hopper 101 for pre-dust reduction of the material entering the crusher 1, and a housing 3 at the bottom of the crusher 1 for separating the crushed material from the water entering the crusher 1. These three parts are connected by flanges or welding to form a continuous and closed material handling channel, thereby blocking the dust escape path in physical space.

[0025] In this embodiment, the crusher 1 mainly includes a sealed outer shell 102, a rotating shaft 104 that penetrates the outer shell and is driven by a motor, and multiple crushing hammers (not shown separately in the figure, belonging to the crushing component) installed on the rotating shaft 104.

[0026] To pre-dust suppression of materials, a guide pipe 4 is installed on the housing 2. The guide pipe 4 is arranged in a ring or U-shape and surrounds the housing 2. A water inlet pipe 403 is installed on one side of the guide pipe 4. Several branch pipes 401 are installed at the bottom of the guide pipe 4. The branch pipes 401 surround the outer wall of the housing 2. The other end of each branch pipe 401 passes through the housing 2 and is equipped with a nozzle 405. Water flows into the guide pipe 4 through the water inlet pipe 403, so that the water flows to each branch pipe 401 and is sprayed out by the nozzle 405 at the end of the branch pipe 401. When materials are put into the housing 2, the nozzles 405 spray water into the housing 2. Since the nozzles 405 are arranged in a ring around the inner wall of the housing 2, the water flow into the housing 2 is more uniform, which can improve the dust suppression effect.

[0027] In this embodiment, nozzle 405 is preferably a solid cone-shaped atomizing nozzle, which is characterized by producing a wide-coverage, fine-particle water mist. These nozzles 405 form a uniform "water mist curtain" above the inner wall of the housing 2. When the material is put into the housing 2 from the top and falls freely, it will completely pass through this water mist curtain. Its surface and the dust mixed in are fully wetted and increased in weight, thereby achieving efficient and thorough pre-dust reduction.

[0028] To prevent dust from settling and adhering to the outer wall of the crushing components of the crusher 1 after encountering water, multiple diversion pipes 402 are provided on one side of the guide pipe 4. The other end of the diversion pipe 402 penetrates the outer shell 102 of the crusher 1 and is equipped with a nozzle 406 at the end. The nozzle 406 is preferably a fan-shaped nozzle or a high-speed jet nozzle, which is characterized by concentrated jet and large impact force. The spray direction of all nozzles 406 is precisely directed towards the movement trajectory of the hammers on the rotating shaft 104. When the crusher is working, the rotating shaft 104 rotates at high speed, and the high-pressure water jet continuously sprayed by the nozzles 406 can "scan" and wash each passing hammer. At the moment when the hammer impacts the material and generates dust, the water jet wets it, which can achieve the effect of dust reduction from the source. In addition, the impact force of the water flow can wash away the mud that begins to accumulate on the surface of the hammer in time, preventing it from drying, hardening or thickening, thereby ensuring that the hammer always maintains a good impact surface and crushing efficiency.

[0029] In order to separate the water sprayed in the crusher 1 from the crushed material, a screen plate 303 is installed in the housing 2 3. The screen plate 303 is set on a slope, and a discharge port 302 is set on the lower side of the slope. The screen plate 303 is equipped with a screen that allows liquid to pass through. When the material falls on the screen plate 303, it will slide down the screen plate 303 towards the discharge port 302, while the liquid and some mud will drip down through the screen, thereby achieving the separation of material from water and mud, obtaining cleaner crushed material, which is convenient for further processing of the crushed material.

[0030] To facilitate control of the water flow rate and switching, a ball valve 404 is installed at the other end of the water inlet pipe 403. The water flow rate can be directly adjusted or the water flow can be turned off through the ball valve 404, which is very convenient.

[0031] To prevent material sliding out of the discharge port 302 from splashing outward, a dust cover 301 is provided on one side of the discharge port 302 to block splashing material and dust, and to prevent dust from splashing upward and causing injury to the operator.

[0032] In order to improve the sealing performance of the outer casing 102 and prevent water and dust from overflowing from the outer casing 102 through the gap between the outer casing 102 and the rotating shaft 104, a sealing ring 103 is sleeved on the outer wall of the rotating shaft 104 and the sealing ring 103 is set on the outer casing 102 to improve the sealing performance of the outer casing 102, block dust and water, and further improve the dustproof effect of the crusher 1.
