After crushing, the material smaller than the hole of the sieve plate falls into the lower collecting hopper of the drum screen crusher through the hole of the sieve plate.

Description

A drum type screening crusher

technical field

The utility model relates to a drum type screening crusher and a design method thereof, belonging to the technical field of supervisory machinery equipment.

Background technique

During the electrolytic aluminum production process, the electrolyte blocks cleaned from the anode residues returned from the electrolysis plant and the electrolyte blocks on the pallets dumped from the loading and unloading station need to be crushed to a certain size and then returned to the electrolytic cell for continued use.

For a long time, electrolyte crushing mainly adopts jaw crusher plus impact crusher or roller crusher for secondary crushing. The electrolyte crushing system has problems of low crushing efficiency, high equipment failure rate, heavy equipment maintenance and repair workload, and high labor intensity. The problem has not been solved well. At present, some manufacturers try to replace the impact crusher with the self-grinding machine for secondary crushing, and the output has been greatly increased. However, the material discharged from the self-grinding machine is too fine, almost all of which are powder materials. Conducive to electrolytic production needs.

Utility model content

The purpose of this utility model is: aiming at the defects of the prior art, to provide a drum type screening crusher, which uses the crushed material itself as the medium, realizes crushing through mutual impact and grinding, and its sieve plate is constantly rotating , to realize that the crushed material meeting the size of the crushed material can quickly flow out through the sieve plate, so as to prevent the particle from being too fine due to secondary damage, so as to overcome the deficiencies of the prior art.

Technical scheme of the utility model

A drum-type screening crusher, comprising a crusher rotating drum, a set of support wheels are respectively provided at the front and rear ends of the crusher rotating drum to realize the free rotation of the crusher rotating drum, wherein the middle body of the crusher rotating drum is formed by a sieve plate Enclosed, the lifting plate is parallel to the center line of the crusher rotating drum and evenly distributed on the inner surface of the screen plate. There is a collecting hopper directly below the crusher rotating drum, and the supporting wheels and collecting hopper are fixed on the base to realize the crusher rotation. Roller fixing.

In the aforementioned drum-type screening crusher, a gear bar is provided on one side of the crusher rotating drum, and the drive motor adopts a chain connection mode to cooperate with the gear bar to drive the crusher rotating drum.

In the aforesaid drum type screening crusher, sieve plate supports intersecting each other are provided on the outer surface of the sieve plate.

In the aforementioned drum type screening crusher, a triangular support plate is provided on the non-working surface of the lifting plate.

In the aforementioned drum type screening crusher, the upper part of the collecting hopper is a semicircular structure.

In the aforementioned drum-type screening crusher, the dust cover is arranged directly above the rotating drum of the crusher and can be connected to both sides of the top of the collecting hopper.

Due to the adoption of the above technical scheme, compared with the prior art, the utility model is a new type of grinding equipment with two functions of crushing and screening. It uses the crushed material itself as the medium, through mutual impact and grinding To achieve crushing, the drum-type screening crusher is equipped with a lifting plate with crushing function in the crushing chamber. Under the designed rated speed, the crushed materials will be lifted to a certain height, and the material will be crushed by the mutual impact and grinding effect of falling materials. At the same time, the special lifting plate inside also plays a role in further strengthening the crushing. After crushing, the material smaller than the hole of the sieve plate falls into the lower collecting hopper of the drum-type screening crusher through the hole of the sieve plate (because the sieve plate keeps rotating, Quickly sieve the materials that reach the crushing size, effectively avoiding the secondary crushing of the crushed materials), and continuously discharged by the conveying equipment. The utility model has large crushing ratio, high production capacity, low energy consumption, simple structure, and high degree of product particle size guarantee. Compared with the support method of dynamic and static pressure bearings, the design of supporting rollers is more adaptable to the environment, less investment, and less difficult to maintain. Compared with the gear meshing transmission method, the cylinder adopts the chain drive method, which also has the advantages of strong environmental adaptability, less investment, and less difficulty in maintenance. . The metal and unbreakable sundries contained in the material can be discharged from the end of the crusher by regularly emptying the material, which will not affect downstream production and equipment.

The hole of the sieve plate is specially designed to effectively reduce the occurrence of material clogging. The sieve plate and the lifting plate are made of wear-resistant materials and have a long service life.

Detailed ways

The utility model is used as a further detailed description below in conjunction with the accompanying drawings, but not as any limitation to the utility model.

Embodiment of the present utility model: a design method of a drum-type screening crusher. The crusher lifts the crushed material to a certain height, and realizes crushing through the mutual impact and grinding action of the material falling. The material falls into the lower collecting hopper of the drum screening crusher through the sieve plate hole, and is continuously discharged by the conveying equipment, so as to realize the function of crushing and screening the crushed material at the same time.

Among them, the middle part of the rotating drum of the crusher is surrounded by a sieve plate, and the sieve plate bracket is used as a support. The crusher is supported by supporting wheels and driven by a chain to make it rotate. plate.
