Abstract
The utility model relates to a feeding blocking prevention method for a biomass gasification furnace and a device. The device comprises a material level meter, a stirring device and an automatic control device. Mutual feedback happens to the stirring device and the material level meter via the automatic control device. When a material is detected by the material level meter, an electric signal is transmitted to the automatic control device, and the stirring device is started for stirring. When the material drops below the material level meter, an electric signal is generated to be transmitted to the automation control device, and stirring is stopped. Therefore, stable feeding of the biomass gasification furnace can be realized, problems of raw materials are blocked due to unmatched feeding speed and irregular raw materials can be solved for the hopper, and a method for automatic control according to the material stacking situation can be realized at the same time.
Description
Technical field
The utility model relates to a kind of biomass gasifying furnace anti-blocking device in feeding, relates in particular to a kind of charging automatic anti-blocking control device of realizing, and belongs to biomass thermal chemical reversion technical field.
Background technology
In actual production and large-scale pilot experiment, biomass gasifying furnace generally adopts bucket elevator-hopper-screw feeder feeding manner, and feed rate often needs bucket elevator and screw feeder to jointly control.When bucket elevator delivery rate with screw feeder motor speed is not mated, during raw materials size irregularity, add elevating hopper bottom size less, raw material can be deposited in hopper, causes fed material from being blocked.In actual production process, to gasification furnace charging monitoring and adjustment, be all that this means expend time in by manual and monitoring in real time, efficiency is lower.Charging is stable is the condition precedent that guarantees gasification furnace smooth operation, realizes feed system and do not stop up in gasification furnace actual production, and smooth operation is very important.
Summary of the invention
The utility model relates to a kind of biomass gasifying furnace anti-blocking device in feeding, can realize biomass gasifying furnace charging stable, solve hopper because of the problem of the raw material obstruction that feed rate is not mated, raw material irregularity causes, realized a kind of method of automatically controlling according to solid accumulation situation simultaneously.
For achieving the above object, the utility model is taked following technical scheme:
A biomass gasifying furnace anti-blocking device in feeding, it comprises hopper, level-sensing device, mixing device and automatic control device, wherein,
Described level-sensing device is arranged on hopper one side, its depth of probe is 1/4 hopper height, this level-sensing device distinguishes that for detecting in time material feedback signal transmit, when material rises to level-sensing device or drop under level-sensing device, level-sensing device can detect in time distinguishes that material feedback signal transmit;
Described mixing device comprises mixing device motor, S. A. and shaft, wherein, described S. A. is deep into 3/4 position in hopper along hopper line of centers, it is of a size of 10～15cm, and described S. A. bottom is divided into 3 shafts of well-distributed, described shaft and S. A. are at 45 °, and and bucket wall between distance be 5cm;
Described automatic control device comprises mixing device motor autonomous cruise speed system and level-sensing device chromacoder, wherein, described mixing device motor autonomous cruise speed system is for controlling mixing device motor start-stop according to level-sensing device signal, in the time of under material is positioned at level-sensing device, mixing device motor standing time can be realized control lag 15～20s, thereby guarantee that material in hopper fully enters screw feeder
Described mixing device and level-sensing device feed back mutually by automatic control device, when level-sensing device detects material, electric signal transmission is to automatic control device, starting mixing device stirs, in the time of under material drops to level-sensing device, produce electric signal transmission to mixing device motor autonomous cruise speed system, stop stirring.
Above-mentioned anti-blocking device in feeding adopts automatic identification, signal feedback and inverse feedback to realize the control of material level in hopper, has reduced the fed material from being blocked causing because of many reasons, and this automatic controllable system is very convenient, useful in biomass gasifying furnace operational process.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model content is described further.
As shown in Figure 1, anti-blocking device in feeding consists of autonomous cruise speed system 1, level-sensing device 2 and mixing device.Mixing device comprises mixing device motor 3, S. A. 5 and shaft 6.Level-sensing device 2 and mixing device motor 3 feed back mutually by autonomous cruise speed system 1, realize charging choke preventing function.3/4 position during S. A. 5 deeply struggles against along hopper 4 line of centerss, is of a size of 10～15cm.S. A. 5 bottoms are divided into 3 shafts 6, and shaft 6 undersized are in S. A. 5 sizes, at 45 ° with rotation 5, be uniformly distributed, and the about 5cm of distance between hopper 4 walls, as shown in Figure 2.
As shown in Figure 1, in gasifier operation process, raw material constantly drops in hopper 4, through screw feeder 8, carry, enter in gasification furnace 9, when not mating because of speed or raw material irregularity causes the hopper 4 former charge bridges in below to pile up, raw material material level in hopper 4 rises, when material level touches level-sensing device 4, level-sensing device 2 produces signal and is transferred to automatic control device 1, automatic control device 1 change over signal is also controlled startup mixing device motor 3, S. A. 5 rotarily drives shaft 6 thereupon and stirs, break the hopper 4 former charge bridge states in below, raw material recovers normal transport, now, material level can decline, when material level drops to level-sensing device 2 below, level-sensing device 2 produces signal and is transferred to automatic control device 1, automatic control device 1 change over signal control lag 15～20s stop mixing device motor 3, complete choke preventing function.
Obviously; the above-mentioned specific embodiment of the present utility model is only for the utility model example is clearly described; and be not the restriction to the utility model embodiment; to those skilled in the art; can also easily make on the basis of the above description other pro forma variation or substitute, and these changes or alternative also by within being included in the definite protection domain of the utility model.
