Description

Technical Field

[0001] The utility model relates to the technical field of slag discharging of biomass boilers, and particularly relates to a slag discharging device for biomass boilers. Background Technique

[0002] A biomass boiler is a boiler device that uses biomass fuel for combustion. The fuel is fed into the furnace by a screw feeder, where it is gradually preheated, dried, ignited, and burned under the action of high-temperature flue gas and primary air. A large amount of volatile matter is released during this process, and the combustion is intense. After the generated high-temperature flue gas flushes the main heating surface of the boiler, it enters the economizer and air preheater of the boiler's tail heating surface, then enters the dust collector, and finally is discharged into the atmosphere through the chimney. The unvaporized fuel moves towards the rear of the grate until it is completely burned, and finally a small amount of ash residue falls into the slag discharge port behind the grate. Biomass boilers will generate a large amount of ash residue after combustion, and a common biomass boiler slag discharging device is usually used for the slag discharging treatment of automatically outputting and discharging the slag collected at the slag discharge port.

[0003] In the prior art, the biomass boiler slag discharging device does not have a high-temperature slag treatment structure for cooling and heat exchange and a pre-treatment structure for crushing agglomerated slag. It is not convenient to cool and utilize the high-temperature ash residue generated by the biomass boiler for heat exchange and energy conservation. At the same time, when encountering slag ash with insufficient cooling of softened or molten ash particles, it cannot be pulverized, so it is not convenient to uniformly screw out the ash residue for full reuse of resource fertilization, and thus it is impossible to improve the utilization rate of the biomass boiler slag.

[0004] Therefore, it is necessary to design a biomass boiler slag discharging device to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a biomass boiler slag discharging device, which adds a high-temperature slag treatment structure for cooling and heat exchange and a pre-treatment structure for crushing agglomerated slag to the designed biomass boiler slag discharging device, so as to facilitate the full reuse of uniformly screwing out the ash residue for resource fertilization, improve the utilization rate of the biomass boiler slag, and thus solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A biomass boiler slag discharging device, comprising a slag discharging device main body. Inside the slag discharging device main body, a control cavity and a slag conveying cavity are sequentially arranged from left to right. A first motor is embedded and installed on one side of the control cavity close to the slag conveying cavity. A first bearing seat is installed on the inner wall of the slag conveying cavity far from the first motor. A slag conveying screw is rotatably installed between the output end of the first motor and the side adjacent to the first bearing seat. A controller panel is embedded and installed inside the control cavity on the front surface of the slag discharging device main body. A slag discharging valve pipe is installed through the inside of the slag conveying cavity at the left side of the bottom of the slag discharging device main body. A slag inlet is opened through the inside of the slag conveying cavity at the top of the slag discharging device main body. A crushing mechanism is installed through the inside of the slag inlet at the top of the slag discharging device main body. A slag receiving hopper is installed on the top of the crushing mechanism. A heat exchanger is installed inside the slag receiving hopper. An inlet liquid pump and an outlet liquid pump that are connected through the heat exchanger are sequentially installed on the right side of the top of the slag discharging device main body from front to back.

[0008] As a preferred solution of the present utility model, a crushing pair roll is installed inside the crushing mechanism. A second motor is embedded and connected to one end of the crushing pair roll on the left side of the crushing mechanism. A second bearing seat is rotatably connected between the inner wall of the crushing mechanism and the other end of the crushing pair roll. Crushing tooth plates are installed at the front and rear ends of the inner wall of the crushing mechanism.

[0009] As a preferred solution of the present utility model, a connecting square pipe is provided at the top of the slag receiving hopper.

[0010] As a preferred solution of the present utility model, an inlet liquid channel and an outlet liquid channel are sequentially arranged through the right side of the slag discharging device main body inside the right side of the heat exchanger. The output pipeline of the inlet liquid pump is connected through to the inlet liquid channel, and the input pipeline of the outlet liquid pump is connected through to the outlet liquid channel.

[0012] As a preferred solution of the present utility model, a display screen and a plurality of control buttons are provided on the controller panel, and the controller panel is electrically connected to the first motor, the crushing mechanism, the inlet liquid pump, and the outlet liquid pump.

[0013] Beneficial effects: In view of the problem that the slag discharging device of biomass boilers in the prior art does not have a high-temperature slag treatment structure for cooling and heat exchange and a pre-treatment structure for crushing agglomerated slag, which makes it inconvenient to screw out uniform ash slag for full reuse of resource fertilization, and thus unable to improve the utilization rate of biomass boiler slag. In the present utility model, by providing a slag receiving hopper with a heat exchanger, it is convenient to conduct energy-saving heat exchange utilization and cooling treatment on the high-temperature slag generated by the biomass boiler, and through the provided crushing mechanism, the slag after cooling and heat exchange can be crushed and agglomerated, so as to facilitate the screw conveyor to conduct screw output slag discharging treatment. The structure is simple and has a high-temperature slag treatment structure for cooling and heat exchange and a pre-treatment structure for crushing agglomerated slag, thus facilitating the full reuse of uniform ash slag for resource fertilization by screw output, and further improving the utilization rate of the slag discharged from the biomass boiler.
