Description

Hammer crusher

Technical field

The present invention relates to a kind of disintegrating apparatus that is used for industries such as feed, food, chemical industry, medical treatment, especially relate to a kind of hammer crusher.

Background technology

Beater disintegrating machine is made up of charging aperture, body, rotor, hammer leaf, sieve sheet and pressure screen frame (unit) thereof, motor, discharging opening etc. usually, during work, by the driven by motor rotor, make epitrochanterian hammer leaf rotation, material enters the back from charging aperture and is pulverized by the continuous hammering of hammer leaf, material powder after the pulverizing passes the sieve aperture of sieve sheet, discharges from the pulverizer discharging opening.There is following problem in the pulverizer of prior art:

After material advanced pulverizer, hammer leaf and material rotated together, and hammer leaf and material relative velocity can diminish, and pulverizer requires hammer leaf to material relative velocity height for improving crush efficiency.

Summary of the invention

The object of the invention is to overcome above-mentioned prior art defective, provides a kind of and can effectively improve the crush efficiency hammer crusher.

Purpose of the present invention is achieved through the following technical solutions, hammer crusher, mainly comprise charging aperture, hammer leaf, rotor, sieve sheet and press screen frame (unit), discharging opening, body, motor, also comprise and decide the hammer grillage, the described grillage of hammering into shape surely is fixed on the pulverizer charging aperture, surely hammer grillage and the parallel relative installation of hammer leaf Plane of rotation into shape, and a spacing is arranged.Hammer leaf when rotation, not can with hammer grillage surely into shape and contact.When material enters, be subjected to form a material ring that rotates after the hammer leaf hammering, material was pulverized once more after material ring bump was hammered grillage surely into shape, hammered grillage simultaneously surely into shape and had also lowered material ring rotary speed, the relative velocity of follow-up hammer leaf and material hammering is increased, thereby improve crush efficiency.

The sieve sheet is installed in presses on the screen frame (unit), presses the below of screen frame (unit) to be provided with contiguous block, and contiguous block is installed vibrating motor down, and this vibrating motor is connected with pressing screen frame (unit) by contiguous block.Make by isolation mountings such as springs and to press screen frame (unit) and body to separate, make sieve sheet and press screen frame (unit) independently to vibrate, sieve sheet and hammer grillage surely into shape and do not bump, also do not collide with hammer leaf.During the vibration of sieve sheet, make sieve aperture constantly obtain cleaning, improve greatly, effectively improve the screen blinding phenomenon by the ability of sieving of comminuting matter.

Surely the spacing of hammering grillage and hammer leaf Plane of rotation into shape is that the 1-50 millimeter is proper, and this spacing is neglected material pulverizing requirement greatly and decided, and thinner powder can select less spacing.Spacing can be adjusted by the width of regulating the hammer leaf separation sleeve, changes the hammer leaf separation sleeve of different in width, can reach the purpose that grillage and hammer leaf Plane of rotation spacing are hammered in change surely into shape, perhaps by adjusting the thickness of deciding the hammer grillage this spacing is regulated.

Surely hammer grillage quantity into shape and can be one or more, hammer grillage surely into shape, be arranged in parallel with the hammer leaf Plane of rotation often for tabular according to the width of pulverizer inner chamber.Surely hammer that grillage length will stretch into the material ring and hammer leaf is overlapping into shape, but do not contact with rotor.Surely hammer into shape two protuberances are set on the grillage, flat shape can be any one of U font or polygon or circular arc, also can be the combination between them, and protuberance and charging aperture are fixed.

For increasing wearability and toughness, hammer grillage surely into shape and can adopt high strength alloy steel to make, perhaps make at ordinary steel surface soldered high strength alloy steel.

The present invention can apply to horizontal pulverizer, also can apply to the pulverizer of vertical crusher or other type.

Decide hammer grillage pulverizer by being equipped with of said structure configuration, can both keep bigger relative speed difference to material at pulverizer mouth hammer mills, thereby help improving crush efficiency, further improve by the uniformity of comminuting matter.

Description of drawings

Fig. 1 is the first embodiment of the invention structural representation.

Fig. 2 is the generalized section of A-A among Fig. 1.

Fig. 3 is the second embodiment of the invention structural representation.

Fig. 4 is the generalized section of B-B among Fig. 3.

The specific embodiment

The present invention is described in further detail below in conjunction with accompanying drawing and the specific embodiment:

Pulverizer as shown in Figure 1 and Figure 2, it is a horizontal pulverizer, by charging aperture 1, hammer leaf 2, rotor 3, hammer grillage 4, motor 6, discharging opening 7, body 8, sieve sheet 9 and press screen frame (unit) 13 etc. to form into shape surely.

Surely it is relative with hammer leaf 2 Plane of rotations and keep 5 millimeters spacings to hammer grillage 4 into shape, hammers grillage 4 and hammer leaf 2 and material surely into shape and meets mutually and touch part and can adopt high strength alloy steel.

Hammer leaf 2 is divided into 4 groups of installations, adopts separation sleeve to fix between every group of hammer leaf.During hammer leaf 2 rotation, can not contact with hammering grillage 4 surely into shape, relative with hammer leaf 2 Plane of rotations, hammer surely that grillage length will stretch into the material ring and hammer leaf is overlapping into shape, but do not contact with rotor.Surely hammer into shape two protuberances are set on the grillage, flat shape is the U font, and protuberance and charging aperture are fixed.When material when charging aperture 1 enters, be subjected to hammer leaf 2 hammerings and with hammer grillage 3 bumps surely into shape, after material is obstructed, the suitable hammering speed of favourable raising and hammer leaf, effectively raising is to material grinding efficient.

Fig. 3, shown in Figure 4 is another embodiment of the present invention.This pulverizer is a kind of horizontal pulverizer, its basic structure is identical with embodiment shown in Fig. 1, Fig. 2, the sieve sheet is installed in presses on the screen frame (unit), but below pressure screen frame (unit) 13, be provided with contiguous block, contiguous block is installed vibrating motor 11 down, and this vibrating motor is connected in aggregates with the pressure screen frame (unit) by contiguous block, will press screen frame (unit) and sieve sheet and body 8 thereof to separate by spring 12 isolation mountings such as grade, make sieve sheet 9 and pressure screen frame (unit) 13 thereof independently to vibrate, sieve sheet 9 is not collided with hammer leaf 2.The amplitude of sieve sheet 9 is at the 1-5 millimeter, and vibration frequency is 50 hertz.Can make the vibration of sieve sheet under vibrating motor 11 effects, thereby improve stifled sieve phenomenon, to material grinding such as the high fibers of little sieve aperture fine powder material high-moisture, effect is obvious especially.

The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all belongs within the scope of technical solution of the present invention any simple modification, equivalent variations or modification that above embodiment did.
