Description
Technical field: the utility model relates to a kind of stoker.
Background technology: adopt the double belljar stoker to come to be main frame coal feed on the existing producer gas generator, this stoker mainly seals by bell jar, its weak point is that the trim between bell jar and the bell jar seat is vulnerable to damage, and gas leak is serious, the influence safety in production.
Summary of the invention: the purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of good airproof performance, long service life, moushroom valve stoker easy to maintenance are provided.
The utility model includes main shaft, valve body, feed-pipe and expansion pipe, sealing member and casing; Casing includes cover plate, housing and base; Base is provided with discharge port; Valve body includes upper and lower valve and intermediate valve; Last valve is provided with opening for feed, and following valve is provided with discharge port, and the intermediate valve top is provided with boss, and valve is provided with the storing mouth, and main shaft is connected with intermediate valve by key, and following valve is fixed on the base, and intermediate valve is positioned at down above the valve; Last valve cooperates with the intermediate valve boss and is contained in above the intermediate valve; Be connected by slide key between last valve and the housing; The opening for feed place is provided with expansion pipe on the last valve, and feed-pipe is connected with expansion pipe.Main shaft is located by connecting by bearing and bearing support and cover plate and base.
During the supporting use of the utility model and producer gas generator, coal charge enters intermediate valve through feed-pipe and expansion pipe and last valve opening for feed, along with intermediate valve rotates, when intermediate valve storing mouth was corresponding with following valve discharge port, valve discharge port and base discharge port entered in the producer gas generator under the coal charge process.
The utility model is applicable to and the supporting use of producer gas generator.Also be applicable to the weight feed of general solid materials processing.
The utility model good airproof performance, long service life, easy to maintenance, ability with automatic compensation wear and tear, when intermediate valve rotated the generation wear and tear, last valve and intermediate valve were to lower slip, and the wearing and tearing that three valve body junctions, upper, middle and lower are produced all are compensated.
Description of drawings: accompanying drawing is the utility model structural representation.
Embodiment: main shaft 7 is connected with base 15 by bearing 17 and bearing support 16, and main shaft 7 is connected with intermediate valve 2 by key 12.Following valve 1 is fixed on the base 15, and last valve 3 cooperates with intermediate valve 2 boss and is contained in above the intermediate valve 2; Be connected by slide key 13 between last valve 3 and the housing 14; The opening for feed place is provided with expansion pipe 6 on the last valve 3, and feed-pipe 5 is connected with expansion pipe 6.Housing 14 is connected up and down with cover plate 4, base 15.Cover plate 4 is connected with main shaft 15 by bearing 11 and bearing support 10.Bearing support 10 is provided with sealing member 8 and sealing gland 9, prevents that the remaining coal gas in the casing from spilling.
