Automatic feed-grate linkage-mode coal hot air furnace

Abstract

The invention discloses an automatic feed-grate linkage-mode coal hot air furnace which comprises a combustion chamber, an ash chamber, a secondary combustion chamber, a heat exchange chamber, a coal storage bunker, a middle-chamber coal hopper, an active coal discharge roller, grate fixing shaft, a grate and a grate shifting roller. The middle-chamber coal hopper is mounted in the combustion chamber, the active coal discharge roller is mounted in the middle-chamber coal hopper, and the coal storage bunker is mounted right above the middle-chamber coal hopper; the grate is formed by grate bars which are independent one another, one ends of the grate bars sleeve the grate fixing shaft while the other ends are lapped on the grate shifting roller, the grate shifting roller drives the grate bars to move in an ups and downs manner in rolling, and coal ash on the grate can fall into the ash chamber. The automatic feed-grate coordinated-type coal hot air furnace has the advantages that coal can be stored and automatically fed, more than 10 hours combustion can be sustained by one-time adding of the coal, and the problem that a specially-assigned person is needed to be on duty at night in the greenhouse is solved; a linkage mode of the grate is adopted, so that automatic ash falling is realized, and combustion is facilitated.

Description

technical field [0001] The invention relates to a coal-fired hot-blast stove, in particular to an automatic coal-charging grate linkage type coal-fired hot-blast stove, which belongs to the technical field of agricultural equipment. Background technique [0002] Warming in winter is an important part of the greenhouse industry, and energy consumption has become a large part of the operating cost of the greenhouse. In Europe, the cost of heating the greenhouse in winter is about 30% of the total operating cost of the greenhouse, and the energy consumption required for warming accounts for more than 25% of the entire energy budget. The heating of the greenhouse in winter consumes a lot of energy and the operating cost is too high, which largely limits the improvement of the production efficiency of the greenhouse. The hot blast stove is a kind of high-efficiency heat exchange equipment that can quickly heat a large greenhouse area with less energy consumption. It quickly blo...

Problems solved by technology

[0003] However, the existing coal-fired hot blast stoves require the staff to add coal every 1 or 2 hours, and the temperature fluctuates greatly. The staff cannot rest normally at night, and the work is very hard.

[0004] In addition, since the grate of the existing coal-fired hot blast stove is fixedly installed in the combustion chamber, the grate cannot be moved, so it is easy to accumulate ash on the grate, which is not conducive to combustion.
