Abstract

The utility model belongs to an adjunctive device of a boiler. Concretely, the utility model relates to an automatic vibration compound sieve. The utility model is suitable for a positive rotation chain-grate boiler. The automatic vibration compound sieve is composed of a cam, a vibration handle, a vibration arm, the compound sieve, a gear wheel, a chain, etc., wherein, a rotary drum axle is tightly matched with the gear wheel; a big gear is matched with the gear wheel by the chain in a rotation mode; a big gear wheel axle is matched with a shaft sleeve arranged on a machine frame in a slide mode; the cam is arranged on the big gear wheel axle and is tightly matched with the big gear wheel axle; the cam is connected with the vibration handle fixed on the vibration arm; the vibration arm is fixed on a shaft of the compound sieve. The utility model uses the power of rotary drum rotation in a stratification coaling device causes the compound sieve to be always in a sieving and moving state. The utility model has the advantages that the fired coal is effectively prevented from blocking sieve holes, the continuous uniform stratification coal supply can be realized, the aims of high efficiency and energy-saving can be achieved, and at the same time, the work strength is reduced.

Description

Automatically shake composite screen

The utility model belongs to boiler affiliated equipment, more precisely is a kind of automatic vibrations composite screen, and being applicable to just changes chain-grate boiler.

The layering coal supply apparatus that is just changeing at present chain-grate boiler generally adopts fixedly composite screen, when coal-fired moisture content is bigger, when being subjected to the sleet factor affecting, fire coal often blocks sieve aperture, be unfavorable for coal-fired layering, usually by fireman's manual cleanup, waste time and energy, labour intensity is bigger, look after for the moment less than, coal-fired layering is not smooth, and heat generation rate descends, and wastes energy.

In view of this, the purpose of this utility model is to provide a kind of and guarantees that coal-fired layering shakes composite screen smoothly automatically, the utility model utilizes the power that drum rotates in the layering coal supply apparatus, make composite screen all the time at the state of sieving, effectively overcome the coal-fired sieve aperture that blocks, realize continuous even laminating coal supply, reach energy-efficient purpose, reduced labour intensity simultaneously.

The purpose of this utility model realizes by following technical measures: shake composite screen automatically by cam, vibration handle, vibrations arm, composite screen, gear, compositions such as chain, wherein, drum axle and gear tight fit, gear wheel by chain and gear rotation movingly, Large Gear Shaft During is slidingly matched with the axle sleeve of device on frame, cam gear is on Large Gear Shaft During, with the Large Gear Shaft During tight fit, cam be fixed on the vibration handle of vibrations on the arm and be connected, the vibrations arm be fixed on composite screen spool on.

In conjunction with the accompanying drawings structure of the present utility model is further described in detail.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a left view of the present utility model.

Fig. 1 is embodiment of the present utility model.

With reference to Fig. 1, shake composite screen automatically by cam 5, vibration handle 4, vibrations arm 10, composite screen 9, gear 2, chain 3 compositions such as grade, wherein, drum axle 11 and gear 2 tight fits, gear wheel 6 is rotatably assorted by chain 3 and gear 2, Large Gear Shaft During 7 is slidingly matched with the axle sleeve 8 of device on frame 1, and cam 5 devices are on Large Gear Shaft During 7, with Large Gear Shaft During 7 tight fits, cam 5 be fixed on the vibration handle 4 of vibrations on the arm 10 and be connected, vibrations arm 10 be fixed on composite screen 9 spool on.

During use, the drum gear drives the gear wheel running by chain, the flange of cam whenever circle on the vibration composite screen axle the vibration handle once, make composite screen be in the periodic vibration state, fire coal on the compass screen surface is in the state of sieving all the time, can effectively coal-fired layering be handled, improve the thermal efficiency of boiler, realize energy-efficient purpose.

Claims

1, a kind of automatic vibrations composite screen, by cam, the vibration handle, the vibrations arm, composite screen, gear, compositions such as chain, it is characterized in that: drum axle and gear tight fit, gear wheel by chain and gear rotation movingly, Large Gear Shaft During is slidingly matched with the axle sleeve of device on frame, cam gear is on Large Gear Shaft During, with the Large Gear Shaft During tight fit, cam be fixed on the vibration handle of vibrations on the arm and be connected, the vibrations arm be fixed on composite screen spool on.
