Description

Technical Field

[0001] The utility model relates to the field of mineral processing equipment, in particular to an automatic high-efficiency impact crushing device. Background Art

[0002] To separate useful minerals from ore, the ore must first be crushed to separate the useful minerals from the gangue. Sometimes, to meet specific particle size requirements for subsequent operations, additional crushing is necessary. The goal is to separate the useful minerals from the gangue, or even different useful minerals, or to achieve a particle size that meets the requirements of the separation process. In the ore crushing process, crushing equipment is broadly divided into two categories: crushers and grinding mills, depending on the operation method and the particle size of the crushed product.

[0003] At present, jaw crushers and cone crushers are more commonly used. These two types of crushers have their own advantages and are widely used, but they also have their own limitations. For example, the crushing amount is small and the crushing process is relatively long, which is not conducive to improving production efficiency. In particular, it is very limited for the crushing of high-hardness minerals with tight time and heavy production capacity tasks. Moreover, the component structure of the current crushing device is relatively complex and inconvenient to maintain. Therefore, there is still a need to develop a device that can operate efficiently and is easy to maintain. If high-power automated crushing operations can be performed, production needs can be significantly met. Existing crushers will generate a large amount of mineral dust when working, and fine dust particles will be dispersed and suspended, which not only affects environmental hygiene, increases equipment wear, causes the loss of useful minerals, but also poses a great threat to the health of workers. Utility Model Content

[0026] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0027] The present invention is described more fully below with reference to the accompanying drawings, which illustrate various aspects of the present invention. The present invention may be implemented in various forms and should not be construed as limited to the various aspects of the present invention presented in this implementation section. Unless otherwise defined, all terms used herein (including industry terms) have the same meanings as commonly understood by persons of ordinary skill in the art to which the present invention pertains.

[0028] Various aspects of the present invention will be described below with reference to the accompanying drawings, which are schematic illustrations of idealized configurations of the present invention. As such, variations in the shapes of these illustrations are to be expected, for example, as a result of manufacturing techniques and / or tolerances. The various aspects of the present invention shown in the drawings may not necessarily be drawn to scale. Furthermore, some of the drawings have been simplified for the sake of clarity. Consequently, the drawings may not depict all of the various components of a given apparatus (e.g., device) or method. Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0029] Reference Figures 1 to 4 As shown, the automated high-efficiency impact crushing device described in the present invention includes a processing chamber 1, the interior of the processing chamber 1 is a cavity, an impact table 2 is provided in the middle position inside the processing chamber 1, and a movable hammer 3 is provided on the processing chamber 1 directly above the impact table 2. The movable hammer 3 passes upward through the top of the processing chamber 1 and is connected to the impact drive mechanism 10 provided on the top of the processing chamber 1. The impact drive mechanism 10 drives the movable hammer 3 to perform vertical lifting movement toward the table of the impact table 2. The mineral or material to be processed is placed on the table of the impact table 2. When the movable hammer 3 descends toward the table of the impact table 2, it impacts and applies pressure to the mineral or material on the table of the impact table 2, so that the mineral or material on the table of the processing chamber 1 is crushed. The impact drive mechanism 10 can use a high-power motor device to achieve a more efficient crushing effect. Preferably, a plurality of diamond grooves distributed in an array are provided on the lower surface of the movable hammer 3 to increase the friction of the contact surface and improve the crushing effect.

[0030] Inside the processing chamber 1, the impact table 2 is flanked by a left baffle 4 and a right baffle 5, respectively. These baffles are positioned flush against the surface of the impact table 2. Each baffle features a feed window 8, angled toward the surface of the impact table 2. Externally stored minerals or materials to be processed enter the processing chamber 1 through the feed window 8 and are loaded onto the surface of the impact table 2. These baffles limit the left and right positions of the impact table 2, preventing leakage from the sides.

[0031] A front lift plate 6 and a rear lift plate 7 are respectively provided on the front and rear sides of the impact table 2 within the processing chamber 1. These plates are closely attached to the front and rear sides of the impact table 2 and are mounted on a lift drive mechanism 9 at the bottom of the processing chamber 1. The lift drive mechanism 9 drives the respective front and rear lift plates 6 and 7 to achieve controlled lifting motion. When the front and rear lift plates 6 and 7 are raised, they limit the front and rear positions of the impact table 2, preventing minerals or materials on the impact table 2 from leaking from the front and rear sides.

[0032] A dozer 11 is disposed behind the rear lift plate 7 on the rear side of the impact table 2 within the processing chamber 1. The dozer 11 is mounted on a shoveling drive mechanism 12, which is mounted on the inner wall of the processing chamber 1. The shoveling drive mechanism 12 drives the dozer 11 to move horizontally toward the impact table 2. The shoveling drive mechanism 12 preferably utilizes a telescopic linear motor. A chamfered outer protrusion is provided at the bottom of the front surface of the dozer 11 to facilitate cutting during shoveling. When the shoveling drive mechanism 12 drives the dozer 11 to reach the surface of the impact table 2, it shovels the minerals or materials on the surface of the impact table 2 forward, pushing the minerals or materials forward and away from the surface of the impact table 2.

[0033] A reserved space is provided in front of the front lift plate 6 in front of the impact table 2 within the processing chamber 1. Below this reserved space is a discharge outlet 13 at the bottom of the processing chamber 1. Processed minerals or materials are discharged downward through discharge outlet 13 for transfer. One side of the reserved space faces the impact table 2, and the other side faces the front inner wall of the processing chamber 1, on which a cleaning mechanism 14 is installed.

[0034] The cleaning mechanism 14 includes a mounting mask, a filter, an air suction pipe and a dust suction pump. The mounting mask of the cleaning mechanism 14 is arranged on the front inner wall of the processing chamber 1, and the filter is tilted on the mounting mask. The interior of the mounting mask is connected to the air suction pipe, and the air suction pipe is connected to the external dust suction pump. The minerals or materials processed on the table of the impact table 2 are pushed to the reserved space by the shovel 11, and then fall into the discharge outlet 13 and are discharged and transferred outward. The mineral dust generated in this process will be attracted by the cleaning mechanism 14 in the reserved space, and the gas will be discharged outward after being filtered by the filter of the cleaning mechanism 14. The blocked mineral dust particles fall from the filter to the discharge outlet 13 below, and are collected together and discharged and transferred outward.

[0035] During implementation of the present invention, in the initial state, the front and rear lifting plates 6 and 7 on the front and rear sides of the impact table 2 are at their maximum height. The front and rear lifting plates 6 and 7 are higher than the impact table 2 surface and act as limiters. The left and right sides of the impact table 2 surface are limited by the left baffle 4 and the right baffle 5. Thus, a container for accommodating minerals or materials is formed on the impact table 2 surface. When loading begins, the minerals or materials stored externally enter the processing chamber 1 through the feed windows 8 on the left baffle 4 and the right baffle 5, and are poured onto the impact table 2 surface until loading is completed.

[0036] Then, pressure crushing begins. Driven by the impact drive mechanism 10, the dynamic hammer 3 approaches the surface of the impact table 2. The minerals or materials on the surface of the impact table 2 are crushed under the high-power pressure of the dynamic hammer 3. Depending on the actual situation, the dynamic hammer 3 is repeatedly raised and lowered multiple times under the drive of the impact drive mechanism 10 to achieve a sufficient crushing operation. After the crushing is completed, the dynamic hammer 3 is raised to the standby position under the drive of the impact drive mechanism 10. The front and rear lifting plates 6 and 7 on the front and rear sides of the impact table 2 are lowered to below or flush with the surface of the impact table 2 under the drive of their respective lifting drive mechanisms 9.

[0037] Then, driven by the shovel drive mechanism 12, the pusher shovel 11 moves horizontally toward the impact table 2. When the shovel drive mechanism 12 drives the pusher shovel 11 to the surface of the impact table 2, it shovels the minerals or materials on the surface of the impact table 2 forward, pushing the minerals or materials forward and away from the surface of the impact table 2. The minerals or materials processed on the surface of the impact table 2 are shoveled into the reserved space, then fall into the discharge outlet 13 and are discharged and transferred outward. The cleaning mechanism 14, located on the front inner wall of the processing chamber 1, is activated as needed. The mineral dust generated during this process is attracted by the cleaning mechanism 14 in the reserved space. After passing through the filter screen, the trapped dust particles fall from the filter screen to the discharge outlet 13 below and are discharged and transferred outward. After the operation is completed, the front and rear lifting plates 6 and 7 on the front and rear sides of the impact table 2 are driven by their respective lifting mechanisms 9 to their initial positions, and the next crushing operation begins. The entire operation is fully automated.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
