Abstract
The utility model provides a static electricity removing device used for preventing powder static electricity electrically shocking human body and explosion accidents. The utility model discloses a fully automatic powder static electricity removing device, relating to an ion generator whose upper end is provided with a flange disk. The inner cavity of a housing is provided with a high pressure module which is connected with a corona terminal, and the corona terminal is fixed on a base plate. An air pressure signal pipe and a signal cable of the ion generator are respectively connected with corresponding interfaces of a controller, and a wiring terminal plate, a program controller, a pressure switch and a power supply are arranged in the controller. An air switch is arranged on the housing. Ion wind is used for neutralizing the static electricity of objects, which means that positive charges and negative charges are neutralized. The technology of removing electricity by the ion wind is applied in the process of powder feeding, and the electricity which is carried by the powder is lowered below a safety margin. A gas-electricity interlocking system is used for ensuring that the power supply can be cut off when the wind stops, and the accidents of electric shock of the static electricity for human bodies and explosion can be efficiently overcome.
Description
One, technical field:
The utility model belongs to the safety engineering field, in particular for preventing that powder electrostatic is to the electric shock of human body and the static eraser of blast accident.
Two, background technology:
In order to eliminate the electrostatic hazard of powder, people have done number of research projects, the method that has found some to reduce and prevent electrostatic hazard, for example, can be by reducing velocity of medium, adding methods such as antistatic agent, humidification reduce or eliminate static from process aspect harm.Use consumer appliance eliminate static be exactly the reversed polarity charging neutrality medium that produces with consumer appliance with electrostatic charge.Main at present consumer appliance commonly used has self-inducting, additional power source formula and radioactive ray formula.
The electrical efficiency that disappears of radioactive ray formula consumer appliance is a contradiction with safety.For safe in utilization, strict restriction is established a capital in the selection of radioactive source and radiation metering really in the radioactive ray formula consumer appliance.Therefore, the electric energy power that disappears of radioactive ray formula consumer appliance is minimum usually.
The electric principle that disappears of self-inducting consumer appliance is that the electrostatic field of using charged powder self makes the induction electrode tip of ground connection produce corona discharge, eliminates the electrostatic charge of powder self by the reversed polarity ion of corona discharge generation.Therefore, when the electric field strength of powder is little after to a certain degree, corona discharge no longer takes place in the electrode of self-inducting consumer appliance, so the powder electrostatic lotus can not be eliminated fully, still exists certain danger.
At present, most popular consumer appliance is an additional power source formula Xelminator.Additional power source formula consumer appliance is of a great variety, comprises AC power formula, direct current unipolarity and bipolarity consumer appliance.Wherein, the ion wind type consumer appliance is developed in order to overcome the less shortcoming of conventional consumer appliance sphere of action, its advantage is by the wind-force effect, make the useful effect space of consumer appliance increase many, but be not specifically designed to the consumer appliance that powder electrostatic is eliminated, have only Artificial Control to carry out powder electrostatic and eliminate.
Three, summary of the invention:
The purpose of this utility model overcomes above-mentioned not enough problem exactly, and a kind of automatic powder static eraser is provided, and adopts the automatic tracking type electric control that disappears, and makes the powder residual charge reduce to minimum, satisfies the produced on-site requirement.
The technical scheme that the utility model is adopted for achieving the above object is: the automatic powder static eraser, relate to ion generator, described ion generator upper end is a ring flange, in the housing inner chamber high-pressure modular is housed, high-pressure modular connects the corona terminal, and the corona terminal is fixed on the base plate, and ion generator air pressure signal pipe, signal cable are connected with controller the corresponding interface respectively, connecting terminal block, program controller, pressure switch and power supply are installed in the controller, air switch is arranged on the housing.
Also be connected to transducer on the described controller.
The utility model has the advantages that: utilize ion wind that object static is neutralized, it is the positive and negative charge neutralization, the ion wind deionization technology is applied to powder blanking process, body of powder electrification is reduced to below the safety margin, gas-the lock system is electrically connected in employing, disconnected power down source has overcome electric shock and the blast accident of powder electrostatic to human body effectively when guaranteeing blowing-out.
In the commercial Application process, when charged powder passed through the flange form ion generator, the most of static of powder was neutralized by the reversed polarity ion, and remaining electrostatic charge is detected by the powder electrostatic transducer and feeds back to computer blurs controller.Fuzzy controller carries out fuzzy reasoning to the electrostatic signal and the set-point of feedback, and the result controls program control high-pressure modular by inference, thereby regulates the ion output polarity and the output variable of flange form ion generator, the final purpose that realizes eliminating powder electrostatic.
The static of powder is eliminated numeric ratio and is seen Table 1
Table 1 powder electrostatic is eliminated the numerical value comparison sheet
| The preceding charge-mass ratio (μ C/kg) of the electricity that disappears | 0.1351 | ?0.1995 | ?0.2233 | ?0.2762 | ?0.3060 |
| Electricity back charge-mass ratio (μ C/kg) disappears | 0.0023 | ?0.0036 | ?0.0055 | ?0.0042 | ?0.0066 |
Found out by data in the table: this utility model electric effect that disappears is obvious.
Four, description of drawings:
Accompanying drawing is the utility model structural representation.
Five, embodiment:
Automatic powder static eraser as shown in Figure 1, being used for polypropylene powder static eliminates, its ion generator upper end is a ring flange 6, in housing 2 inner chambers high-pressure modular 8 is housed, high-pressure modular 8 is connected with 6 corona terminals 9, the quantity of corona terminal 9 is decided according to actual conditions, for example can be 8 or more, corona terminal 9 is fixed on the base plate 5, under the control of high-pressure modular, launch ion flow, ion generator air pressure signal pipe 3, signal cable 4 is connected with controller the corresponding interface respectively, connecting terminal block 12 is installed in the controller, PLC program controller 11, pressure switch 14, Switching Power Supply 13 has air switch 10 on the housing 7, the program controller 11 of controller also is connected to transducer 15, a controller can connect a plurality of ion generators and transducer simultaneously, can connect 4 groups as figure.
During work, the ion generator flange is mounted on the polypropylene flash distillation still port of export, connect source of the gas 1, the powder electrostatic transducer is installed on the bottom of packaging bag, the fuzzy controller of computer is installed in control room's (or being installed in the scene), energized, powder promptly are eliminated static behind the ion generator passage, then packing.Transducer imports the powder electrostatic signal into computer fuzzy controller, and controller removes to control high-pressure modular according to the polarity and the size of input signal, thereby reaches the ionic size of control ion generator and the purpose of polarity.
