Abstract

The utility model discloses a rubber fine crusher, which comprises a charging hopper, a crushing chamber, a movable knife, a fixed knife, a knife holder, a shell, a cooling device, a discharging device and a bracket, wherein the charging hopper is fixed on the upper part of the shell, the crushing chamber is positioned under the charging hopper, the fixed knife is fixed on the inner end surface of the crushing chamber, the movable knife is fixed on the rotating knife holder which is positioned in the middle of the crushing chamber, the discharging device is positioned under the knife holder and the cooling device is tightly attached to the outside of the crushing chamber. The rubber fine crusher can crush rubber particles of 6-12MM into fine rubber granules of 1-3MM, and the rubber particles of 6-12MM can be charged into the crushing chamber by the charging hopper. Rubber and fibres in the rubber particles can be completely separated by depending the shearing and the tearing of the movable knife and the fixed knife in the process of crushing. The obtained mixed materials of the rubber particles and the fibres after crushing can be transported into a next process by a blower for separation, and consequently, the rubber and the fibres can be completely separated. The utility model has the advantages of reasonable structure and convenient operation.

Description

The rubber fine 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 fine crusher, and it is the tiny rubber grain of 1-3mm that the 6-12mm rubber grain after it will be pulverized by intermediate crusher is at normal temperatures further pulverized.

For achieving the above object, the utility model includes material bin, pulverizing chamber, moving knife, stationary knife, tool rest, shell, cooling device, blanking device and support, wherein, material bin is fixed in shell upper, pulverizing chamber is positioned at the material bin below, and stationary knife is fixed on the inner face of pulverizing chamber, and 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 cooling device then fits in the pulverizing chamber outside.

Described 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 support.

The beneficial effects of the utility model are: it can will be sent into the tiny rubber grain that 6-12mm micelle in the pulverizing chamber is broken into 1-3mm by material bin, and in crushing process, the shearing that can rely on moving knife and stationary knife with tear, rubber in the micelle is separated fully with fiber, the micelle that obtains after the pulverizing, fiber mixture pass through the next process-sorting that delivers into of blower fan, thereby rubber is separated fully with fiber, its structure is comparatively reasonable, very easy to use, and have 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 a cutaway view of the present utility model

Accompanying drawing 2 is the side view (removing moving knife) of accompanying drawing 1

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 accompanying drawing 1 and the accompanying drawing 2: rubber fine crusher of the present utility model includes material bin 1, pulverizing chamber 9, moving knife 8, stationary knife 3, tool rest 7, shell 2, cooling device 4, blanking device 6; Wherein, material bin 1 is fixed in shell 2 tops, and material bin 1 can adopt double-deck interstitital texture, the noise during with reduction work; Pulverizing chamber 9 is positioned at hopper 1 below, and stationary knife 3 is screwed, and around the inner face annular spread of pulverizing chamber 9; 8 of the moving knife that matches with stationary knife 3 are screwed on the rotary knife base 7 that is positioned at pulverizing chamber 9 middle parts, tool rest 7 is the hexagonal shape, and by being fixed on motor 10 on the support 5 (motor can adopt heat overload protector, to guarantee that motor can not be damaged under abnormal conditions) drive, moving knife 8 is fixed on the inner face at tool rest 7 each angle, stationary knife 3 and moving knife 8 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 7, and its screen cloth is a vibratory sieve, can employing activity rotational structure, and 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; 4 of cooling devices fit in pulverizing chamber 9 outsides, are connected with the cooling water of circulation in it, to reduce the temperature of pulverizing chamber 9, 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 rubber grain via the 6-12mm that obtains after the pulverizing of rubber intermediate crusher is sent in the material bin 1 of fine crusher by conveyer, and enter pulverizing chamber 9 via hopper 1, rubber grain in pulverizing chamber 9 in the shearing of stationary knife 3 and moving knife 8 with tear under the effect and be broken, fiber in the rubber grain is separated fully with rubber, during pulverizing, by changing the size that screen cloth changes mesh, can control the fineness of discharging particle, pulverize the micelle of coming out from pulverizing chamber 9, fiber mixture passes through the next process-sorting that delivers into of blower fan, thereby rubber is separated fully with fiber.The utility model adopts full-enclosed structure and reasonably inner combination, and the noise during work is greatly diminished.
