Description

Biomass particle feeding and burning device for heating equipment

Technical Field

The utility model relates to a heating equipment technical field especially relates to a living beings granule pay-off burner for heating equipment.

Background

The biomass particle combustion device is a combustion device of high-density solid fuel pressed by biomass agricultural and forestry wastes (such as straws, branches, barks, shells and the like), wood processing leftover materials (such as wood powder, sawdust, wood shavings, leftover materials and the like), building mould waste plates, square timbers, decorative wood leftover materials and other organic matters, generates high-temperature hot flame in a suspension, boiling and semi-gasification cracking combustion mode, and transfers the heat of the high-temperature flame to thermal equipment in a radiation and convection heat transfer mode. The biomass particle combustion device is environment-friendly combustion equipment, provides a brand-new technical scheme for modifying clean fuel for petrochemical fuel equipment, is popular with customers, and is widely applied to various heat energy industries such as boilers, die casting machines, industrial furnaces and kilns, incinerators, smelting furnaces, kitchen equipment, drying equipment, food drying equipment, ironing equipment, paint baking equipment, road building mechanical equipment, industrial annealing furnaces, asphalt heating equipment and the like. However, the existing biomass particle combustion device (as shown in fig. 1 and 2, the existing biomass particle combustion device) is generally formed by combining a bin body 10 and a furnace body 20, a feeding screw 101 is arranged in the bin body 10, the feeding screw 101 is connected with a material conveying pipeline, a discharge port of the material conveying pipeline is connected with a combustion box 201, the combustion box 211 is located in the furnace body 20, a control panel 102 is arranged on the bin body 10, the control panel 102 can control biomass particles to enter the bin body 10, the existing material conveying pipeline has two modes of free blanking and open front end of a direct-pushing combustion box, but the structure of the existing material conveying pipeline has defects:

the first mode, the biomass particle burner of free blanking formula, the conveying pipeline is installed in burning box 201 upper end one side, it has the feed inlet to open in burning box 201 upper end, the biomass particle gets into the feeding spiral from the feed bin body and freely falls into burning box 201 through the conveying pipeline in, then burn at burning box 201, because the biomass particle is in burning box 201, its burning biomass particle process biomass particle does not flow, the ash content after the burning constantly overstock in burning box 201, the overstock can make the burning condition worsen, thereby can cause vicious circle, can burn very fast like this, be unfavorable for long-term use.

Secondly, a feeding hole is formed in one side end of the combustion box 201, the feeding hole and a discharging hole of the feeding pipeline are on the same horizontal line, biomass particles are directly pushed into the combustion box 201 with the open front end from the feeding pipeline of the storage bin body through a feeding screw, the biomass particles are combusted in the combustion box 201, the feeding pipeline and the combustion box 201 are on the same horizontal line, continuous biomass particles enter the combustion box 201 from the feeding hole in the side end, the biomass particles which are continuously fed and are combusted move towards the feeding hole in the open end, the feeding hole without burning ash can be pushed into the combustion box 201, the biomass particles can be insufficiently combusted in the combustion box 201, fuel is wasted, and the overall heat taking efficiency is affected.

In conclusion, for the biomass particle combustion device, the combustion in the combustion box is insufficient, the combustion efficiency is low, and the use requirements of people cannot be met.
