Problems solved by technology

But it still has the following problems: Its multi-stage driven reverse-push grate can meet the different requirements of waste incineration for the frequency of grate movement at different stages. In fact, it can only be adjusted by adjusting the reverse-push furnace The action frequency of the grate is used to adjust the material layer to achieve the purpose of load regulation, and due to the limitation of the grate arrangement angle, the garbage will naturally fall under the action of gravity after being piled to a certain extent; so this structure is also difficult to actively control The thickness of the garbage material layer, so it cannot guarantee that the incinerator can always run at a stable load; in addition, its structure is relatively complicated, and the investment cost of equipment is relatively high

Embodiment 1

[0014] Embodiment 1, the two-stage domestic waste incinerator with adjustable material layer in this embodiment, its structure can be seen from Figure 1, it contains a furnace body 1 with a blanking groove 1a, a Feeder 2, reverse push type fire grate 3, forward push type fire grate 4, air chamber and ash chamber 5 under the fire grate and slag discharger 6 under the slag discharge channel 7, its fire grate sheet contains solid The fixed piece a bound on the furnace body and the movable piece b arranged between the two adjacent fixed pieces at intervals and connected with the reciprocating rod 9, and the grate is divided into front and rear sections along the running direction of the garbage, close to the falling The front section of the hopper 1 is a downward-sloping reverse-push fire grate 3, and the rear section is a forward-push fire grate 4. A height difference H is provided at the junction of the front and rear two sections of the fire grate; Two rows of two-stage fire gr...

Embodiment 2

[0022] Embodiment 2, the two-stage domestic waste incinerator with adjustable material layer in this embodiment, its structure can be seen from Figure 1, and it differs from Embodiment 1 in that its forward-push fire grate 4 is the best Like the reverse-push grate, it is set to incline to the right and down, and the inclination angle β of the grate to the horizontal direction is 20° to 30°. To ensure that the garbage residue fully incinerated by the reverse-push grate can also stay on the forward-push grate for 10 to 30 minutes, and then leave the grate under the double action of the garbage residue's own gravity and the forward-push grate 4 , into the slag discharge channel 6 and output by the slag discharge machine 7. The slag loss-on-ignition rate of this embodiment is ≤3%.

Abstract

A house garbage incinerator of two sections type with material layer being able to be adjusted consists of incinerator body, material feeder, fire grate with front section in positive pushing type and back section in negative pushing type, wind chamber, ash basin, slag releasing channel and slag releasing device. It is featured as setting device for adjusting height of material layer at position of incinerator body with tail end of fire grate in negative type, forming said adjusting device by baffle shaft in bearing base and baffle for adjusting height of material layer as well as driving mechanism for driving baffle shaft.

Description

technical field [0001] The invention relates to a domestic waste incinerator for incinerating domestic waste and having two stages of reverse-push and forward-push grate, especially a domestic waste incinerator that can adapt to a large fluctuation range of physical composition and calorific value. Two-stage domestic waste incinerator with adjustable material layer for waste incineration. Background technique [0002] The domestic waste incinerator provided by Chinese patent 02111455.2 is an ignition self-igniting type domestic waste incinerator with adjustable intake air volume. The air chamber and slag extractor located under the fire grate, wherein the fire grate includes a fixed piece fixed on the furnace body and a movable piece arranged between two adjacent fixed pieces at intervals and connected with a reciprocating rod. The grate is divided into two sections, the front section and the back section along the direction of garbage running. The front section close to th...
