Abstract
The utility model relates to an electrostatic dust collector cathode transmission device. A motor is arranged on the outer side of a case body with one end thereof opened, a ceramic rotating shaft is arranged on the case body and driven by the motor, the bottom surface on the inner side of the case body is an inclined surface inclining with the horizontal plane; and an electric heater and a platinum heat resistor are arranged inside the case body. The bottom surface on the inner side the case body is not easy to accumulate dust. The cathode transmission device can prevent dust from accumulating and adhering to the surface of the ceramic rotating shaft, so as to solve the creepage and short circuit problems due to dust accumulation on the surface of the ceramic rotating shaft. The cathode transmission device has the advantages of reasonable structure, reliable use and convenient maintenance.
Description
Technical field
The utility model relates to the cathode driving device that a kind of electrostatic precipitator is used.
Background technology
Electrostatic dust collector cathode driving device is the device that is used for the transmission negative electrode, achieves vibrations.The primary structure of existing electrostatic dust collector cathode driving device is: the casing top side that an end is uncovered is provided with a motor, and a porcelain rotating shaft of being equipped with on casing is passed through the transmission mechanism transmission by motor.The main deficiency that above-mentioned existing electrostatic dust collector cathode driving device exists is: at work, dust can be accumulated the bottom in casing, temperature fluctuation is big in the casing, the easy dewfall of dust in the casing also sticks to porcelain rotating shaft surface, when dust when porcelain rotating shaft surface adhesion phenomenon is serious, can cause creepage, the short circuit of porcelain rotating shaft, cause electrostatic precipitator normally not move.In addition, in the above-mentioned electrostatic dust collector cathode driving device, because motor is by the rotating shaft of transmission mechanism transmission porcelain, its complex structure degree increases, appearance and size is big, and the installation of porcelain rotating shaft, change inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of electrostatic dust collector cathode driving device, and the bottom in its casing is difficult for the accumulation dust and porcelain rotating shaft surface also is difficult for having dust adhesion.
For achieving the above object, the utility model adopts following scheme: electrostatic dust collector cathode driving device, the casing outside that one end is uncovered is provided with motor, the one porcelain rotating shaft of being equipped with on casing is by the motor transmission, the bottom surface of box inside is the inclined-plane that tilts with horizontal plane, is provided with electric heater and platinum resistance thermometer sensor, in casing.Control circuit in the electric control cabinet of electric heater and platinum resistance thermometer sensor, and electrostatic precipitator is joined, by the temperature in the platinum resistance thermometer sensor, detection casing, by electric heater to heating in the casing, temperature in casing is lower than going up in limited time of dust close dew temperature, by the energising of control circuit control electric heater, when the temperature in the casing is higher than the close dew temperature of dust, by the outage of control circuit control electric heater.
By such scheme as seen, because the bottom surface of box inside is the inclined-plane, the dust major part that drops on this inclined-plane can be slipped to outside the casing, has guaranteed that the bottom surface of box inside is difficult for the accumulation dust, has significantly reduced the amount of dust in the casing; Because the temperature in the casing is not less than the close dew temperature of dust all the time, like this, can avoids the dust dewfall and adhere to the phenomenon on porcelain rotating shaft surface.Thereby creepage, the short circuit problem that have solved porcelain rotating shaft dust stratification and brought.
The utility model is rational in infrastructure, uses reliable, easy to maintenance.
Description of drawings
Fig. 1 the utility model one example structure schematic diagram;
The right view of Fig. 2 Fig. 1.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1
One end of casing 1 is uncovered, and the interior of casing 1 has heat-insulation layer 1c, and the bottom surface 1b of casing 1 inboard is the inclined-plane that tilts with horizontal plane, and the bottom surface 1b of casing 1 inboard and the angle of horizontal plane are 50 °.Be provided with electric heater 5 and platinum resistance thermometer sensor, 7 in casing 1, the terminals of platinum resistance thermometer sensor, 7 stretch out outside the casing 1.Motor 2 is located on the side of casing 1, and the rotating shaft of motor 2 connects with porcelain rotating shaft 4 by shaft joint 3.Be provided with opening 1a on the top of casing 1, be provided with at opening 1a place and seal up a door 6,6 inside of sealing up a door have heat-insulation layer 6a.Open and seal up a door 6, can install or change porcelain rotating shaft 4 easily.
As seen from Figure 1, control circuit in the electric control cabinet of electric heater 5 and platinum resistance thermometer sensor, 7 and electrostatic precipitator is joined, by the temperature in the platinum resistance thermometer sensor, 7 detection casings 1, temperature in casing 1 is lower than the going up of close dew temperature of dust and prescribes a time limit, by 5 energisings of control circuit control electric heater, when the temperature in the casing 1 is higher than the close dew temperature of dust, by 5 outages of control circuit control electric heater, concrete requirement is: when the temperature in the setting casing 1 is lower than 100 ℃, electric heater 5 energisings, temperature in casing 1 reaches 100 ℃, electric heater 5 outages.By heating in 5 pairs of casings of electric heater 1, can guarantee that the temperature in the casing is higher than the close dew temperature of dust all the time, avoids the dewfall of dust.
Referring to Fig. 2
The terminals of electric heater 5 stretch out outside the casing 1, are provided with a protective cover 8 in casing 1 outside, are being covered the terminals of electric heater 5 by protective cover 8.
