Abstract

The utility model discloses a rubber medium crusher, which comprises a lower discharging hopper, a crushing chamber, a movable knife, a fixed knife, a knife holder, a shell, a cooling device, a discharging device and a magnetic separator, wherein the discharging hopper is fixed on the upper part of the shell, the crushing chamber is positioned under the discharging hopper, the fixed knife is fixed on the inner end surface of the crushing chamber, the movable knife is fixed on the rotary knife holder which is positioned in the middle part of the crushing chamber, the discharging device is positioned under the knife holder, a screen mesh of the discharging device is connected with a conveying belt of the magnetic separator and the cooling device is attached to the outer part of the crushing chamber. Rubber blocks which are charged into the crushing chamber by the discharging hopper can be crushed into rubber granules of 6-12MM, steel wires and rubber in the rubber blocks can be completely separated by depending the shearing and the tearing of the movable knife and the fixed knife in the process of crushing and the steel wires can be used and recycled through the magnetic separator. The obtained granules after crushing can be conveyed into subsequent fine crushing equipment by the conveying belt for further processing. The utility model has the advantages of reasonable structure and convenient operation.

Description

The rubber intermediate crusher

Technical field:

The utility model relates to the disintegrating apparatus technical field, especially relates to a kind of rubber crusher tool.

Background technology:

Population, environment, resource are the three big problems that influence China's economic development 21 century, only resolve this three problems, could keep present China rapid economy development, and the utilization again of waste tire rubber resource, relate to two of this three big problems, irreplaceable running stores during rubber tyre uses as automobile, scrap the back because of the tire tread pattern wearing and tearing and arbitrarily abandoned " black pollution " that causes environment, and the enough attention that the serious waste of the very deficient rubber sources of China also do not caused the whole society.

The utility model content:

The purpose of this utility model is to provide a kind of rubber intermediate crusher, and it is processed into the thin piece of 6-12mm rubber with the thick piece of 30-50mm waste old at normal temperatures.

For achieving the above object, the utility model includes down hopper, pulverizing chamber, moving knife, stationary knife, tool rest, shell, cooling device, blanking device, concentration equipment; Wherein, hopper is fixed in shell upper, pulverizing chamber is positioned at the hopper below, stationary knife is fixed on the inner face of pulverizing chamber, moving knife then is fixed on the rotary knife base that is positioned at the pulverizing chamber middle part, blanking device is positioned at the below of tool rest, and its screen cloth links to each other with the conveyer belt of concentration equipment, and cooling device then fits in the pulverizing chamber outside.

Tool rest is the hexagonal shape, and moving knife is fixed on the inner face at each angle of tool rest, and the stationary knife that cooperates with moving knife then is fixed on the inner face of pulverizing chamber in the form of a ring.

Described tool rest is by the driven by motor that is fixed on the frame.

The screen cloth of described blanking device is a vibratory sieve.

The beneficial effects of the utility model are: it can will be sent into the rubber grain that blob of viscose in the pulverizing chamber is broken into 6-12mm by hopper, and in crushing process, the shearing that can rely on moving knife and stationary knife with tear, steel wire in the blob of viscose is separated fully with rubber, steel wire can be recycled by concentration equipment, and the particle that obtains after the pulverizing then can be delivered to follow-up equipment in small, broken bits via conveyer belt and further handle.Its structure is comparatively reasonable, and is very easy to use, and has that blanking is smooth and easy, noise is little, the life-span is long, low power consumption and other advantages.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is an outside drawing of the present utility model

Accompanying drawing 2 is a cutaway view of the present utility model

Accompanying drawing 3 is the side view of accompanying drawing 2

The specific embodiment

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1 ~ 3: rubber intermediate crusher of the present utility model includes down hopper 1, pulverizing chamber 2, moving knife 3, stationary knife 5, tool rest 9, shell 8, cooling device 4, blanking device 6, concentration equipment 7; Wherein, hopper 1 is fixed in shell 8 tops, and hopper 1 can adopt double-deck interstitital texture, the noise during with reduction work; Pulverizing chamber 2 is positioned at hopper 1 below, and stationary knife 5 is screwed, and around the inner face annular spread of pulverizing chamber 2; 3 of the moving knife that matches with stationary knife 5 are screwed on the rotary knife base 9 that is positioned at pulverizing chamber 2 middle parts, tool rest 9 is the hexagonal shape, and by being fixed on motor 11 on the frame 10 (motor can adopt heat overload protector, to guarantee that motor can not be damaged under abnormal conditions) drive, moving knife 3 is fixed on the inner face at tool rest 9 each angle, stationary knife 5 and moving knife 3 constitute shears the herringbone knife structure, so that working angles is more reasonable, energy consumption is lower; Blanking device 6 is positioned at the below of tool rest 9, its screen cloth is a vibratory sieve, can employing activity rotational structure, to prevent the distortion of screen cloth in powerful extrusion process, guarantee the distance of moving knife and screen cloth, thereby make the pulverizing discharging quicker, screen cloth links to each other with the conveyer belt 71 of concentration equipment 7, delivers to concentration equipment 7 with the material after will pulverizing; 4 of cooling devices fit in pulverizing chamber 2 outsides, are connected with the cooling water of circulation in it, to reduce the temperature of pulverizing chamber 2, make the micelle of pulverizing can be not bonding in the high speed crushing process, thereby increase work efficiency and service life of cutter and bearing.

Brief description operation principle of the present utility model once: the tire blob of viscose is sent in the hopper 1 via conveyer, and enter pulverizing chamber 2 via hopper 1, blob of viscose in pulverizing chamber 2 in the shearing of stationary knife 5 and moving knife 3 with tear under the effect and be broken, the material that meets the requirements arrives on the conveyer belt 71 of concentration equipment 7 by the screen cloth of blanking device 6, steel wire with magnetic is held by the magnetic roller 72 in the concentration equipment 7, the rubber that does not possess magnetic then falls down, thereby makes the steel wire in the blob of viscose separate fully with rubber.What do not meet the demands is broken repeatedly till passing through screen cloth in pulverizing chamber 2.By changing the size that screen cloth changes mesh, can control the size of discharging particle.The heat that produces in the shattering process is taken away by the cooling fluid in the cooling device 4.
