The grinder comprises a rack, wherein an enclosure is installed on the rack; a main shaft passes through the rack and is connected with the two end faces of the enclosure via bearing blocks; a feeder and a discharger are respectively arranged at the two ends of the enclosure; a grinding cavity is arranged in the enclosure; knife rests on the main shaft are installed in the grinding cavity; and blades are distributed on the peripheries of the knife rests. The grinder is characterized in that the blades are in clearance fit with the inner walls of the grinding cavity; and the clearance is 1-2mm. The grinder has the beneficial effect that the grinding effect and the power consumption can be considered.

Description

Pulverizer

Technical field

The utility model relates to a kind of pulverizer, belongs to the chemical industry equipment field.

Background technology

Amino film plastics (specifically can referring to GB13454-92) refers to take urea-formaldehyde resin or melamine resin as base material, the industrial chemicals that adds cellulose, curing agent and other additives and make is mainly used in being pressed into the structural members such as tableware, electric switch.Existing amino molding production method and equipment exist automaticity low, the shortcomings such as efficient deficiency, and production equipment wherein mostly is common chemical industry equipment, lacks the specific aim to amino film plastics itself.The shortcomings such as the utility model relates to the pulverizer of in production process, material being pulverized, and existing pulverizer exists production efficiency low, and power consumption is large.

The utility model content

The applicant studies and improves for the prior art above shortcomings, and a kind of efficient pulverizer is provided.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to the utility model for above-mentioned:

The utility model comprises frame, on described frame, casing is installed, main shaft passes described frame and is connected with two end faces of casing by bearing block, described casing two ends arrange respectively feeder and discharger, in described casing, crushing chamber is set, the knife rest that is arranged on main shaft is set in described crushing chamber, described knife rest circumferentially is distributed with blade, the inwall matched in clearance that it is characterized in that described blade and crushing chamber, this gap width are 1mm-2mm.

Technique effect of the present utility model is that the gap between Disintegrating knife and crushing chamber inwall is 1mm-2mm, can take into account crushing effect and power consumption.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the side view of Fig. 1 intermediate slide part.

The specific embodiment

See Fig. 1, the utility model comprises frame 8, and casing 9 is installed on frame, the interior crushing chamber 11 that arranges of casing 9, and main shaft 4 passes crushing chamber 11, and the two ends of main shaft 4 are connected with the end face of casing 9 by bearing block 10.Knife rest 5 is installed on main shaft 4, Disintegrating knife 14 is installed on knife rest 5, blade 14 and crushing chamber 11 matched in clearance, main shaft 4 both sides arrange respectively left wind wheel 13 and right wind wheel 12, and casing 9 two ends arrange feeder 3 and discharger 6.The right-hand member of main shaft 4 connects belt pulley 7, and main shaft 4 connects power source by belt pulley 7 and belt (not shown in FIG.).During the utility model work, main shaft 4 high-speed rotation, effect by left wind wheel 13 and right wind wheel 12 and blade 14 makes the interior generation negative pressure of crushing chamber 11, material is entered by feeder 3, effect due to centrifugal force, material is got rid of to the madial wall of crushing chamber 11, and material is subject to friction between the madial wall of Disintegrating knife 14 and crushing chamber 11, airflow function is pulverized it, simultaneously under the effect of air pressure from 6 sections self-emptyings of discharger.Feeder 3 upper ends of utility model arrange air inlet, are used for replenishing of air-flow.See Fig. 1, Fig. 2, Disintegrating knife 14 circumferentially is distributed on knife rest 5, every circle knife rest 1 or knife rest 2 are one group, knife rest 5 quantity of the present utility model are the 2-3 group, show according to experiment, for the amino film plastics described in background information in the utility model, in the situation that the knife rest diameter is the 200mm left and right, the quantity of every group of Disintegrating knife 14 is 12-14, the quantity of Disintegrating knife 14 is more, and the windage of rotating generation is larger, although the good crushing effect energy consumption is large, the preferred amount of Disintegrating knife 14 of the present utility model is 13, can take into account crushing effect and power consumption.

Gap between the utility model Disintegrating knife 14 and crushing chamber 11 inwalls is set to 1mm-2mm, and preferred version is 1.5mm.This gap width is larger, pulverize output higher, but crushing effect is poor, and the gap is less, good crushing effect, but yield poorly, and power consumption is large, causes production efficiency the, and the disclosed technical scheme of the utility model can for the characteristic of amino film plastics, be taken into account output and efficient.

Claims (1)

1. pulverizer, comprise frame, on described frame, casing is installed, main shaft passes described frame and is connected with two end faces of casing by bearing block, and described casing two ends arrange respectively feeder and discharger, in described casing, crushing chamber are set, the knife rest that is arranged on main shaft is set in described crushing chamber, described knife rest circumferentially is distributed with blade, it is characterized in that the inwall matched in clearance of described blade and crushing chamber, and this gap width is 1mm-2mm.
