Description
Technical Field
The utility model relates to a novel feed bin charge level meter device.
Background
The common level meters include a rotation-resisting level meter, a radar level meter, a heavy hammer level meter and the like. The rotation-resistant material level meter cannot be completely sealed, so that faults such as motor faults, spindle jamming and the like often occur, and real-time monitoring cannot be achieved; the radar level gauge measures the level by means of the reflection receiving time of radar waves, so that a large measuring error is generated when the material flies upward; the heavy hammer material level meter adopts a simple mechanical structure, is easy to generate faults of hammer burying, rope breaking and the like, and is inconvenient for continuously measuring the material level. In the field of material level measurement, no better measuring bin powder exists.
The level meter is a metering instrument for measuring the level of materials in a stock bin/container/storage and the like, converts a level signal (switching value or continuous quantity) into an electric signal (analog signal or digital signal) and transmits the electric signal to the PLC/DCS, and assists an automatic system to control discharging, feeding or stopping feeding so as to keep the level height in the stock bin. The level meter can measure the material level of materials in various states, such as liquid, slurry, ash, powder, particle, block and the like, and is widely applied to various industries.
In the waste incineration industry, the storage bin mainly comprises a lime bin, an active carbon bin, a fly ash bin and the like, and the common characteristic is that solid powder is very fine and has a continuous feeding state; the fly ash stored in the fly ash bin is in a high-temperature state, and needs the level meter to continuously operate all day long, so that higher requirements on the performance and the reliability of the level meter are provided. In the field of material level measurement, no better equipment for measuring powder in a storage bin exists. Therefore, there is a need to develop new silo level measurement techniques and equipment.

The sampling head is arranged in the material below, and compressed air passes through the sampling head and gets into the material below, and the material can be blown under the pressure that constantly risees, detects pressure variation when the manometer, can judge the pile up height of material through the reading.
The main drawback of the existing solutions is the large measurement error. The bulk density distribution of the materials in the bin is not uniform in the three-dimensional space, and the bulk density distribution of different batches of materials above the sampling opening is also possibly non-uniform, so that the gravity of different batches of materials at different moments is irregular. Although the scheme also provides that the material level measurement experiment is carried out on the material in advance, the repeated experiment for many times improves the accuracy of the material level meter during formal measurement, the frequent experiment during the daily operation is impossible, the reliability of the material level meter can be greatly reduced, and the workload of operators is increased. In addition, the purging electromagnetic valve is required to work after the work is finished, so that the purpose of continuously measuring the material level cannot be realized, the service life of the sampling tube is greatly reduced by frequent purging, and the operation cost of the device is indirectly increased.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Unless otherwise defined, all references herein to upper, lower, left, right, front, rear, inner and outer, etc., are to be interpreted as referring to upper, lower, left, right, front, rear, inner and outer, etc., in the drawings to which the invention is applied, and are hereby incorporated by reference.
Example 1
The embodiment 1 of the utility model provides a as shown in fig. 1, novel charge level indicator mainly has fixed plate 1, gasbag pipe 2, buckle 3, buffer tank 4, manometer 5, temperature sensor 6, compressed air jar 7 etc. to constitute. The fixing plate 1 is made of high-temperature resistant materials and is high in stability. The air bag tube 2 is a long, soft and airtight tube, and is also resistant to high temperature. The plurality of buckles 3 clamp the air bag pipe on the fixing plate. The connection mode of buckle and fixed plate is metal bolt connection, is difficult to not hard up.
The upper part of the air bag pipe is connected with the buffer tank 4, and the buffer tank has larger volume but good sealing effect.
Above the buffer tank there is a pressure gauge 5 and a temperature sensor 6 which can detect the pressure and temperature of the gas in the buffer tank. The buffer box is connected with a compressed air interface, and a compressed air tank 7 is arranged beside the buffer box and connected with the buffer box through an electromagnetic valve 8.
The system of example 1 works as follows: the device is integrally installed at the top of a storage bin needing to detect the material level, can adhere to the wall and can also be installed at the middle position. The fixed plate and the length of the air bag pipe are enough to be inserted into the bottom of the storage bin, when the material rises, the lower part of the air bag pipe is submerged, the submerged part of the air bag pipe is flattened, the air pressure of the upper buffer box rises, air pressure data can be obtained through the pressure gauge, when the material rises to the highest position, the air pressure of the buffer box reaches the maximum value at the moment. The materials can correspond to different air pressure values of the buffer box at different positions of the storage bin. Through experiments, the positive correlation formula of the material position and the air pressure can be determined. Atmospheric pressure numerical value converts the signal of telecommunication into, and the DCS center control system is transmitted again, converts material position data into, and the operating personnel can conveniently look over the real-time material height of feed bin. Meanwhile, the material data has high and low level alarm, and when the material reaches a low level value or a high level value, the system can send out alarm. In order to prevent the influence of temperature change on the air pressure, the change of the air temperature is also considered by the calculation program of the material position, the air temperature data of the buffer box is transmitted to the central control system through the temperature sensor, the air pressure data is corrected to the air pressure corresponding to the preset temperature value and then is included in the calculation program of the material position, and the value of the material position can be more accurate.
In order to prevent errors caused by system air leakage after long-term use, the device can be calibrated regularly. The material is firstly emptied, the electromagnetic valve is opened, clean compressed air which is subjected to water removal, oil removal and impurity removal enters the buffer tank, and the air bag pipe is completely opened. When the pressure rises to a calibration set value, the electromagnetic valve is closed, and the calibration is finished.
In addition, the device can also self-check, when compressed air gets into the gasbag pipe, continuously steps up, and pressure rises to the self-check setting value, closes the solenoid valve, if pressure can guarantee that a period of time does not descend, proves that the device does not have the gas leakage problem.
Example 2
The working process of the system of the embodiment 2 is different from that of the embodiment 1 in that when the materials rise to submerge the lower part of the air bag pipe, the submerged part of the air bag pipe is flattened, the submergence can be detected by the laser radar detector 9 in real time, and the material level data is directly transmitted to the central control system.
Due to the isolation effect of the air bag pipe, the materials flying around in the feeding process cannot influence the transmission of radar waves, and the accuracy of detecting the materials by the detector cannot be influenced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions on some technical features, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of the present invention.
