Reference numerals: the air-out device comprises a master slice 1, a positioning groove 11, a hole 12, a groove 13, a screw 14, an air-out piece 2, a bulge 21, an air-out hole 22, a flow sensor 31, an electromagnetic flow valve 32 and a fan 33.
Detailed Description
The following describes an implementation structure of the present invention with reference to the drawings.
Example one
As shown in fig. 1 to 5, a split type fire grate segment comprises a master segment 11 and an air outlet segment 2, wherein a groove 13 is formed in a first end of the master segment 1, the groove 13 is connected with the air outlet segment 2 in a matched manner, an air outlet hole 22 is formed in the air outlet segment 2, and the air outlet segment is in a pyramid shape.
In order to connect the air outlet piece and the master piece, a groove 13 of the air outlet piece is provided with a hole 12, a first end of the air outlet piece is provided with a threaded hole, and the threaded hole is connected with the threaded hole 12 through a screw (of course, the first end of the air outlet piece is provided with a through hole and can be connected through a bolt) so as to fix the air outlet piece 2.
In order to position the air outlet sheet quickly, a positioning groove 11 is further formed in the groove 13, and a protruding portion 21 is further arranged at one end, matched with the positioning groove 11, of the air outlet sheet 2 and is used for being connected with the positioning groove 11.
In order to prevent rubbish from blocking the exhaust vent 22, a split type fire grate piece still includes air volume control device, and air volume control device includes electromagnetic flow valve 32, pipeline, flow sensor 31 and chip, one set of air volume control device is all connected to every exhaust vent 22, and wherein, electromagnetic flow valve 32, flow sensor 31 and exhaust vent 22 are through the pipeline order and are connected, the chip respectively with electromagnetic flow valve 32 and flow sensor 31 electricity are connected, wherein the chip through drive circuit with electromagnetic flow valve 32 electricity is connected.
Further, the split-type fire grate segment further comprises a fan 33, wherein the fan 33 is electrically connected with the chip and provides air volume for the air volume control device, and the chip is electrically connected with the fan through an amplifying circuit.
The working principle is as follows:
because the air outlet hole 22 on the air outlet sheet is a damaged part, when the air outlet hole 22 is damaged, the air outlet sheet is directly replaced, so that the economic cost and the maintenance period can be reduced; in addition, when the air quantity is not controlled, when a certain air outlet hole 22 is blocked or the air outlet quantity of the certain air outlet hole 22 is reduced when the garbage quantity is more, the local combustion of the combustion furnace is insufficient, and meanwhile, due to the reduction of the air outlet quantity of the air outlet hole 22, the local temperature is too high and the air cooling cannot be reasonably carried out, so that the loss of an air outlet sheet is accelerated, and the air quantity control is added; plug up certain exhaust vent 22 or cause the air output of certain exhaust vent 22 to reduce when rubbish volume is more, detect 31 and give the chip with signal transmission by flow sensor, the chip will control the input of corresponding electromagnetic flow valve 32 increase flow, increase the power of fan 33 simultaneously, and then produce the rubbish that this exhaust vent 22 will be plugged up to bigger wind pressure and amount of wind and blow away, increase the oxygen of local position simultaneously, can not cause the local combustion insufficient, adopt local flow control, can not cause whole amount of wind to show to increase and improve the excess air coefficient of grate top combustion area, and then lead to strengthening the burning of rubbish on the grate, make the furnace temperature show and rise.
The above description is only a detailed description of the present invention. The scope of the present invention is not limited thereto, and any changes or simple substitutions which are not thought of through creative work should be covered within the scope of the present invention.
