Abstract
The utility model relates to an impact type powder and particle flow meter, which belongs to electronic metering equipment. The impact type powder and particle flow meter is composed of a test body, a load sensor, a signal amplifier and a data processing system. The utility model is characterized in that the load sensor is arranged on the back of a test board in the test body in the method of surface contact; a box type anti eccentric load structure is used. The utility model has the advantages of simple structure, reliability, high measuring precision and strong applicability, and can be used for the automatic metering, automatic proportioning and automatic control of powder and particle materials in the industries of chemical industries, building materials, foods, electric power, metallurgy, etc.
Description
The utility model provides a kind of impact type powder flowmeter, belongs to a kind of metering outfit in electronic surveying field.
Along with the development of industrial automation, the electronic sensor The Application of Technology, impact type powder flowmeter is applied to building materials, chemical industry, grain, mine more and more widely, controls industries such as gold.Using more impact type powder flowmeter in the market is that momentum with material utilizes differential transformer to become alternating signal, through instrument system alternating signal is handled to outflow again, this old-fashioned flowmeter is complicated in mechanical structure, bulky not only, and poor anti jamming capability.In order to overcome its shortcoming, a kind of improved impact type powder flowmeter appears again on the market, adopt load sensor to replace differential transformer, a transmission rod is installed at the check-out console back side, one end of transmission rod is fixed on the check-out console, the other end is fixed on the first end of weighing of load sensor, through transmission rod the material momentum is passed on the load sensor, utilize load sensor to measure material and drop on the momentum that produces on the check-out console, load sensor output direct current signal send data handling system to handle to outflow after the instrument processing and amplifying.This improved impact type powder flowmeter is compared with old-fashioned flowmeter, physical construction is simple, volume is little, and the anti-environmental interference ability of system is enhanced, but because the momentum signal of material must be delivered on the load sensor from check-out console through transmission rod, so exist measuring accuracy not high enough, simultaneously because load sensor is to contact by transmission rod and check-out console, this way of contact makes physical construction reliable inadequately, is easy to generate fault.
The purpose of this utility model is to provide the impact type powder that a kind of physical construction is reliable, measuring accuracy is high flowmeter.
The impact type powder flowmeter that the utility model provides is made up of detection bodies (1), load sensor (2), signal amplifier (3) and data handling system (4).Described detection bodies (1) comprises housing (1a), charging aperture (1b), rectification mouth (1c), check-out console (1d), flange (1e), division board (1f), demarcates mouthful (1g) and blanking port (1h) etc., its feature is the back side that described load sensor (2) is installed in check-out console (1d), its weigh first side with the face way of contact be fixed on check-out console (1d) all-in-one-piece support (1i) on, an end face of load sensor (2) is fixed on the housing (1a) of detection bodies (1).This impact type powder flowmeter adopts the load sensor of box anti-bias load structure.The principle of work of this impact type powder flowmeter be powder grain material after testing the charging aperture (1b) of body (1) enter in the detection bodies, drop on equably on the tilted-putted check-out console (1d) through the rectification mouth again, be loaded on load sensor (2) the detection load signal at check-out console (1d) back side, this signal is converted to dc signal through load sensor (2), outputting standard signal again after signal amplifier (3) adjust to amplify is transferred to standard signal data handling system (4) then and carries out data such as calculation process provides instantaneous delivery, integrated flow, the flow of putting into several classes.Demarcate for convenient, also be provided with in the utility model detection bodies and demarcated mouthful (1g) and a division board (1f).Since the employed load sensor of impact type powder flowmeter that provides of the utility model directly be fixed on check-out console (1d) all-in-one-piece support (1i) on, reduced the loss of detection load signal in transmittance process, thereby improved measuring accuracy.Simultaneously, because load sensor is fixed between check-out console (1d) and housing (1a), load sensor (2) weigh first side with the face way of contact directly be fixed on check-out console (1d) all-in-one-piece support (1i) on, this way of contact improved the reliability of physical construction.Again since the utility model in load sensor (2) adopted the resistance strain gage sensor of box anti-bias load structure, thereby reduced requirement to the tested material discharged way, make impact type powder flowmeter adaptability provided by the utility model stronger.
Impact type powder flowmeter provided by the utility model has measuring accuracy height (dynamically can reach 1%, static state can reach 0.1%), and anti-environmental interference ability is strong, and physical construction is simple, reliable, and volume is little, and is easy for installation, and adaptability is strong.Be widely used in numerous industries such as building materials, chemical industry, grain, electric power, mine, metallurgy, under the different occasions to the automatic gauge of powder grain material, automatic blending, control etc. automatically.
Description of drawings
1, the utility model provides impact type powder flow meter signal to transmit block scheme.
2, the utility model provides impact type powder flowmeter structure synoptic diagram.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.The housing (1a) of detection bodies in the utility model (1) is made by general steel plate, and check-out console (1d) and support (1i) adopt corrosion resistant plate to make, and the check-out console smooth surface becomes 65 ° of angles to be placed in the detection bodies with surface level.Load sensor (2) adopts box anti-bias load structure precision resister strain-gauge transducer (precision can reach 0.05%), signal amplifier (3) output following standard signal: 0-5V, 0-10V, 0-10mA, 4-20mA.Data handling system (4) can adopt digital instrument, intelligence instrument, also can directly adopt computer system.
Claims (2)
1, a kind of impact type powder flowmeter, by detection bodies (1), load sensor (2), signal amplifier (3) and data handling system (4) are formed, described detection bodies (1) comprises housing (1a), charging aperture (1b), rectification mouth (1c), check-out console (1d), flange (1e), division board (1f), demarcate mouthful (1g) and a blanking port (1h), it is characterized in that described load sensor (2) is installed in check-out console (1d) back side, its weigh first side with the face way of contact be fixed on check-out console (1d) all-in-one-piece support (1i) on, the other end of load sensor (2) is fixed on the detection bodies housing (1a).
