Problems solved by technology

Although continuous and uninterrupted fuel addition can be achieved, there are still some deficiencies in the control of the fuel level of the combustion furnace, and the relationship between the material level and the feed cannot be effectively controlled.
This shows that the prior art scheme is also difficult to meet people's actual needs

Embodiment 1

[0025] It includes a detection signal transmitting device, a detection signal receiving device and a feed control device. A detection signal transmitting device and a detection signal receiving device are arranged on both sides of the furnace 6. The side is horizontally corresponding, and the horizontal emission line of the detection signal emission port is the positioning position of the charge combustion.

[0026] The detection signal transmitting head 1 of the detection signal transmitting device is connected to the detection signal transmitting head support 3, the detection signal transmitting head support 3 is connected to the furnace 6, and one end of the detection signal transmitting head support 3 is outside the furnace 6 for transmitting Head interface, and the other end is a detection signal emission port 13 in the furnace 6; the furnace 6 is connected with the feed pipe 7. The detection signal receiving head 12 of the detection signal receiving device is connected t...

Abstract

The invention relates to a burning furnace burden level control design method, a control device and a control method. The design method comprises the following steps of: designing a settled position and a relative position for burning furnace burden according to the sizes of a hearth and a furnace mouth or by combining burning firepower; stopping a feeding device from feeding by using a feeding control device when the position of the furnace burden in the hearth is higher than the settled position; and starting the feeding device to feed by using the feeding control device when the position of the furnace burden in the hearth is lower than the settled position, wherein the position of the furnace burden after the feeding device is started each time is higher than the settled position; the position which is higher than the settled position is the relative position for burning the furnace burden; and in a stable burning interval, the furnace burden is burnt between the settled position and the relative position. The feeding process is controlled by using the settled position of the burden level of a fuel in the hearth; and through reciprocating work, the position of the fuel in the hearth is stabilized, sustained burning is realized, and a persistent long-term fire demand is met.

Description

technical field [0001] The invention belongs to household furnaces or stoves with solid fuel, and relates to a design method, a control device and a control method for a combustion furnace material level control of a fully automatic feed combustion furnace in which the fuel is combusted from top to bottom. Background technique [0002] The combustion device that uses the top-down combustion method for fuel has been continuously developed. The existing feeding device is "closed biomass fuel feeding device", patent number: CN200820185125.6. The flap door device of the device, the flap door device is provided with a fuel inlet, the lower end of the screw device communicates with a metering silo, and the metering hopper is equipped with a fuel level detection device; another example is the applicant CN201110072JS3.7 of "A Fully Automatic Feeding Combustion Furnace and Furnace Fuel Feeding Device", which adopts the method of mobile replenishment and push-type feeding, and realize...
