Description
Technical field
The utility model belongs to level gauging technical field, specifically a kind of device detecting biomass fuel material level.
Background technology
Level-sensing device has a wide range of applications in the industrial production, and its effect is the material level change checking solid material in container.Common level-sensing device mainly contains following a few class: capacitance level meter, ultrasonic material level detection unit, radar type level-sensing device, laser type level-sensing device, radio frequency admittance level-sensing device, Plumb-bob Material Level Meter, ray type level-sensing device, weighing level indicator and resistance move formula level-sensing device etc.
Different level-sensing devices has measuring principles different separately and the scope of application, in use has respective defect.Sensor as capacitance level meter must be arranged on Cang Ding, and rapier must vertically insert, and shell bottom line reliably must connect earth mat; Ultrasonic material level detection unit can not at high temperature work, and the change of propagation medium can affect measuring accuracy; Easily there is the faults such as probe stammerer in radar type level-sensing device, was not suitable for hot environment; Laser type level-sensing device is subject to Band Interference, and cost is high; The specific inductive capacity of radio frequency admittance level-sensing device to material has requirement; Ray type material level is in respect of radioactive contamination and cost is higher; Resistance move formula level-sensing device can not high temperature resistant, easily break down, simply can only check the material level that rolls off the production line, controlling level can not be shown in real time.On the whole, the non-mechanical level-sensing device that direct signal is measured also easily occurs that high temperature signal is elegant and contaminated phenomenon of popping one's head in.But, as Plumb-bob Material Level Meter can only be arranged on container top, easily there is disorder cable phenomenon in mechanicalness level-sensing device; Weighing level indicator equipment is huge, take up room large.In biomass pyrolysis process, temperature high (about 500 DEG C), material component is numerous and diverse, there are high-temperature fuel gas, carbon dust, tar, high-temperature heat carrier, wherein tar can bond sensor and being corrosive, therefore environment is very harsh, and need in production run the real-time test and monitoring of level of filler material, existing common level-sensing device can not be applicable to the material-level measure of biomass fuel.
Chinese patent literature CN202195853U discloses a kind of blade type level gage for level gauging in the bulk material containers such as sack cleaner, belong to resistance and move formula level-sensing device, it comprises blade, transmission shaft, propulsion system and signal acquisition and control device, the output shaft of propulsion system is connected with transmission shaft, transmission shaft is fixed with blade, and signal acquisition and control device is connected with propulsion system.The detection signal of signal acquisition and control device derives from propulsion system, and material-level measure signal acquisition point is unreasonable.In addition, owing to being that propulsion system directly drive transmission shaft, then the installation site of propulsion system is from hopper close together, works in high temperature environments, and propulsion system and signal acquisition and control device can shorten the life-span.
Utility model content
In order to solve prior art existing defects, the utility model provides one and is suitable for hot environment work, detects material level living beings torque type level-sensing device accurately.
In order to realize above object, the technical scheme that the utility model is taked is: a kind of living beings torque type level-sensing device, comprise the feeler lever with resisting force sheet and the propulsion system driving feeler lever to rotate, and signal acquisition and control device, install torque rotary speed sensor between described propulsion system and feeler lever, described signal acquisition and control device is electrically connected with torque rotary speed sensor.
Further, between described torque rotary speed sensor and feeler lever, gear train is set.
Described gear train is made up of chain, the drive sprocket being installed on torque rotary speed sensor and the driven sprocket that is installed on feeler lever.
Compared with prior art, the utility model utilizes torque rotary speed sensor to detect the torque/speed variable signal of feeler lever, the controlling level of material is changed into the digital signal of torque/speed, show controlling level in real time by signal acquisition and control device, and material level is precisely controlled.Also have the following advantages:
1, a feeler lever only need be set and just can realize accurately automatically detecting or controlling, smart structural design material level bound;
2, feeler lever is separated by gear train interval with signal acquisition and control device, and the electronic component of signal acquisition and control device can be made away from hopper, not by the impact of the severe rugged environments such as high temperature, burn into dust, tar bonding.
Accompanying drawing explanation
Fig. 1 is the structural representation of living beings torque type level-sensing device.
Embodiment
As shown in Figure 1, living beings torque type level-sensing device is primarily of propulsion system, torque rotary speed sensor 5 and gear train, feeler lever composition.
Be made up of base 1, motor 2, reductor 3, shaft coupling 4, torque rotary speed sensor 5, chain 6, drive sprocket, driven sprocket, hopper 7, resisting force sheet 8, feeler lever 9, bearing seat 11 and signal acquisition and control device 10.
Base 1 installs propulsion system, and propulsion system comprise motor 2, reductor 3 and shaft coupling 4, and reductor 3 is connected by shaft coupling 4 with torque rotary speed sensor 5.Torque rotary speed sensor 5 is electrically connected with signal acquisition and control device 10.
Gear train is made up of chain 6, drive sprocket and driven sprocket.Drive sprocket is installed on torque rotary speed sensor 5, and driven sprocket is installed on feeler lever 9 one end.
Bearing seat 11 installs hopper 7 and feeler lever 9.Feeler lever 9 other end to stretch in hopper 7 and installs a resisting force sheet 8 at end.
The principle of work of living beings torque type level-sensing device is: motor 2 drives reductor 3 to rotate, reductor 3 output speed < 30 turns/min.Reductor 3 is rotated by shaft coupling 4 motoring torque speed probe 5, and torque rotary speed sensor 5 drives feeler lever 9 to rotate by driving chain 6, and resisting force sheet 8 rotates together along with feeler lever 9.When resisting force sheet 8 rotates, the resistance produced due to different controlling level is different, thus the rotating torque conveying to torque rotary speed sensor 5 is also different, signal acquisition and control device 10 to collect signal registration different, therefore the registration of signal acquisition and control device 10 just can react the height of material level in hopper.
Living beings torque type level-sensing device before use, need draw initial registration to signal acquisition and control device zeroing in hole capital after selling all securities situation.During use, according to the measurement change in resistance of concrete material level and the proportionate relationship of initial registration, just the height of material is directly determined by the registration of signal acquisition and control device 10, simultaneously the controlling level that bound controls in container automatically can be set according to actual service condition, thus reach Real-Time Monitoring material level and automatically control the object of controlling level.
Rule of thumb known, can by changing size, shape, the quantity of resisting force sheet, or change the range of torque rotary speed sensor thus adapt to the monitoring of various level of filler material height, usable range is widely.
