Abstract

The utility model relates to a controllable conveyer for a pulverizer, which includes the pulverizer. The controllable conveyer is characterized in that: the controllable conveyer comprises a power unit, a speed reducer, a conveying auger, a feed inlet, an air-replenishing and residue-returning orifice and an air-replenishing and residue-returning hopper; the power output end of the power unit is connected with the input end of the speed reducer; the output end of the speed reducer is connected with the conveying auger; a feed housing is sleeved on the conveying auger; the top of the feed housing is the feed inlet; the discharge outlet of the feed housing is connected with the feed inlet of the air-replenishing and residue-returning hopper; the discharge outlet of the air-replenishing and residue-returning hopper is connected with the feed inlet of the pulverizer; and the upper end of the air-replenishing and residue-returning hopper is the air-replenishing and residue-returning orifice. The utility model has the advantages that: since the conveyer is an external independent unit, the conveyer cannot be affected by the operation of the pulverizer; after the needed material quantity is set, the conveyer can keep a stable conveying state, consequently, the production of the pulverizer can be kept stable, and the pulverizer can operate at full capacity, and can reach the highest capacity.

Description

A kind of controllable type feeding device that is used for pulverizer

(1) technical field:

The utility model relates to a kind of size reduction machinery, especially a kind of controllable type feeding device that is used for gradation type cutter formula pulverizer.

(2) background technology:

The feeding device (see figure 3) of existing pulverizer connects one with pulverizer; form an airtight system; conveyer device﹠apos is owing to be subjected to wind-force system in, and is fast during the material of the influence conveying of blast, the time slow; the time many; the time few, cause pulverizer load unstable, influenced the pulverizer operate as normal; often need to shut down maintenance, reduced the production capacity of pulverizer greatly.

(3) utility model content:

The purpose of this utility model is to design a kind of controllable type feeding device that is used for pulverizer, it can solve the deficiencies in the prior art, because this device is external self-contained unit, so can not be subjected to the influence of pulverizer work, stable working state, the production efficiency height.

The technical solution of the utility model: a kind of controllable type feeding device that is used for pulverizer, comprise pulverizer, it is characterized in that it by power unit, decelerator, conveyer device﹠apos, charging aperture, charging housing, mend wind and return cinder notch and mend wind and return slag bucket and constitute; The input of the clutch end connection reducer of said power unit; The output of said decelerator connects conveyer device﹠apos; Said conveyer device﹠apos is with the charging housing outward; The top of said charging housing is a charging aperture; The discharging opening of said charging housing connects mends the charging aperture that wind returns slag bucket; The discharging opening that said benefit wind returns slag bucket is connected with the charging aperture of pulverizer; Said benefit wind goes back to the upper end of slag bucket and returns cinder notch for mending wind.

Above-mentioned said power unit is a variable-frequency motor, and is connected with decelerator according to the V-belt.

The course of work of the present utility model: the belt pulley on the variable-frequency motor, pass through the V-belt, drive the belt pulley on the decelerator, after slowing down, the drive auger rotates, and by the rotation of auger, material is pushed into benefit wind by the charging housing returns in the slag bucket, mend wind and return the interior material of slag bucket by deadweight, the negative pressure wind in flowability and the pulverizer is drawn in the pulverizer chamber.

Superiority of the present utility model: because this device is external self-contained unit, so can not be subjected to the influence of pulverizer work, setting under the situation of required inventory, this device can keep stable defeated material state, make pulverizer produce held stationary, operate at full capacity, and reach the highest production capacity.

(4) description of drawings:

Fig. 1 is the related a kind of structural representation that is used for the controllable type feeding device of pulverizer of the utility model.

Fig. 2 is applied to the schematic diagram of pulverizer for the related a kind of controllable type feeding device that is used for pulverizer of the utility model.

Fig. 3 is the prior art constructions schematic diagram.

Wherein, 1 is motor, and 2 is decelerator, and 3 is conveyer device﹠apos, and 4 is charging aperture, and 5 are the charging housing, and 6 for benefit wind returns cinder notch, and 7 for benefit wind returns slag bucket, and 8 is pulverizer, and 9 mend wind for charging returns the skull body.(4 is charging aperture among Fig. 3, and 6 is to mend wind to return cinder notch among Fig. 3)

(5) specific embodiment:

Embodiment: a kind of controllable type feeding device (seeing Fig. 1, Fig. 2) that is used for pulverizer, comprise pulverizer 8, it is characterized in that it by power unit, decelerator 2, conveyer device﹠apos 3, charging aperture 4, charging housing 5, mend wind and return cinder notch 6 and mend wind and return slag bucket 7 and constitute; The input of the clutch end connection reducer 2 of said power unit; The output of said decelerator 2 connects conveyer device﹠apos 3; The said conveyer device﹠apos 3 outer charging housings 5 that are with; The top of said charging housing 5 is a charging aperture 4; The discharging opening of said charging housing 5 connects mends the charging aperture that wind returns slag bucket 7; The discharging opening that said benefit wind returns slag bucket 7 is connected with the charging aperture of pulverizer 8; Said benefit wind goes back to the upper end of slag bucket 7 and returns cinder notch 6 for mending wind.

Above-mentioned said power unit is a variable-frequency motor 1, and is connected with decelerator 2 according to the V-belt.(seeing Fig. 1, Fig. 2)
