Abstract
The utility model discloses a powder electrostatic monitor comprising a monitor shell and a constant volume dumpable charge chamber arranged in the monitor shell, wherein the charge chamber is connected with the charge display list out of the monitor shell. The charge chamber supports on the monitor shell through a charge chamber shaft and can rotate around the shaft. The charge chamber can also support inner the monitor shell and have an on-off movable door arranged at the lower opening. The powder electrostatic monitor can detect the charge quantity (Muc/kg) in unit quality of powder material directly and has the advantages of accurate results, simple structure and convenience for using, thus is suitable for powder electrostatic detecting in petrochemical enterprises. The utility model is not only suitable for predicting and evaluating the electrostatic burning and explosion risks of powder silos, but also can get ideal electric eliminating efficiency and reliable monitoring when being used together with the powder electrostatic eliminating devices.
Description
Affiliated technical field
The utility model relates to a kind of electrostatic monitoring device that the petrochemical industry powder material is carried that is used for.
Background technology
The powder material of petroleum chemical industry (as polyolefin) is sent in the operation process of storehouse at wind, can produce a large amount of static, and these charged materials not only can adsorb tube wall or be bonded to piece, directly influences product quality and wind send efficient; And along with the gathering of static, very easily bring out the burning and the blast of feed bin powder, even lead to major accidents such as fatal crass, therefore, the situation of change of monitoring powder electrostatic timely and accurately seems very important.Present electrostatic monitor all is by electrostatic potential in monitoring conveying pipeline or the feed bin and the strong and weak size that reflects material volume charge amount indirectly of static electric field, these class methods are because of can not directly reflecting the absolute value of the charged quantity of electric charge of feed bin material, easily cause bigger test error, bring difficulty for the prediction and the assessment of static charge, and directly influence is eliminated with efficient to effective control of static charge.
Summary of the invention
In order to overcome the prior art above shortcomings, the purpose of this utility model is to provide a kind of electrostatic monitor that can directly detect powder electrostatic lotus amount, and it not only has simple in structure, and accurate measurement, easy to detect.
The technical scheme in the invention for solving the technical problem is: this powder electrostatic monitor, comprise the monitor housing, be provided with dumpable constant volume electric charge chamber in the monitor housing, the external electric charge indicator gauge of this constant volume electric charge chamber and monitor interconnects.
In a preferred implementation, electric charge chamber shaft support is passed through on the inwall of monitor housing in described constant volume electric charge chamber, and can be with electric charge chamber shaft swing.
Another preferred embodiment in, described constant volume electric charge chamber is supported on the monitor inner walls, its end opening is provided with able to turn on or off dodge gate.
Adopt powder electrostatic monitor of the present utility model, owing in the monitor housing, be provided with constant volume electric charge chamber, send in the material process at wind, the electric charge chamber just can collect the charged material of certain mass, and directly detect the quantity of electric charge (μ c/kg) of material unit mass, continuous data is accurate, and is easy to detect; Also because pivot structure or end opening are adopted in constant volume electric charge chamber is movable door structure, can carry out the material collection easily and topple over, be beneficial to repeated detection, realized timely monitor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is specified.
Fig. 1 is the structural representation of first embodiment of the utility model powder electrostatic monitor;
Fig. 2 is the structural representation of another embodiment of the utility model powder electrostatic monitor.
Embodiment
Shown in Figure 1 is the utility model powder electrostatic monitor first embodiment.The two ends of the monitor housing 1 of tubulose all are fixedly connected with ring flange, so that the feeding pipe of monitor series connection with it is connected; On the tube wall of monitor housing 1, be provided with one and hold the cavity of constant volume electric charge chamber 2, constant volume electric charge chamber 2 is supported on the monitor housing 1 by electric charge chamber rotating shaft 2-1, the Faraday cylinder structure is adopted in constant volume electric charge chamber 2, and promptly constant volume electric charge chamber 2 is the double-barrel structure of mutually insulated socket.By rotating the handle outside the monitor housing 1 or driving cylinder, drive affixed with it electric charge chamber axle 2-1 swing and constant volume electric charge chamber 2 is tilted, when constant volume electric charge chamber 2 tilts, its upper oral part stretches in the monitor housing 1, one inclined-plane of infraoral and cavity matches, form tilting cup-like structure, behind the collected constant volume electric charge of the material chamber 2, with the constant volume electric charge chamber 2 mutual electric charge indicator gauges that are electrically connected, just directly show the quantity of electric charge size in the constant volume electric charge chamber 2, to finish the detection of the unit mass quantity of electric charge, detection finishes, and backward rotation electric charge chamber rotating shaft 2-1 makes constant volume electric charge chamber 2 be in vertical position, its infraoral breaks away from inclined-plane in cavity and open-minded, the constant volume quantity of electric charge 2 has become tubular structure from cup-shaped, and the material of being gathered is toppled over along infraoral and is back in the conveying pipeline, so that acquisition testing once more.This structure can conveniently be used, and does not influence wind again and send material unimpeded in conveying pipeline.
Shown in Figure 2 is another embodiment of the utility model powder electrostatic monitor.Except that the tilting structure of constant volume electric charge chamber 2 be different from embodiment illustrated in fig. 1, all the other structures are identical.Faraday's cartridge type structure is still adopted in constant volume electric charge chamber 2, and the cylindrical shell of constant volume electric charge chamber 2 is fixedly attached on the inwall of monitoring body housing 1, this constant volume electric charge chamber 2 be provided with can opening and closing dodge gate 2-3, dodge gate 2-3 is connected on the outer cylinder body of constant volume electric charge chamber 2 by door pivot 2-2, same by turning handle or driving cylinder, drive the opening and closing that affixed with it door pivot 2-2 carries out dodge gate 2-3, finish sampling when closing dodge gate 2-3, the electric charge indicator gauge shows the quantity of electric charge size of tested material; Open dodge gate 2-3 and gather material and then toppled over and send conveying pipeline back to and form empty tube shape, material still can be by therebetween.It has characteristics simple in structure, easy to use.This monitor not only can be used for powder material warehouse static and fires dangerous prediction and assessment, particularly unites use with the powder electrostatic cancellation element, can reach desirable disappear electrical efficiency and monitoring reliably.
The above only is two preferred implementations of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement (as tilting structure mode of constant volume electric charge chamber etc.), these should be considered as belonging to protection domain of the present utility model equally.
