Abstract
Provided is a cement kiln tube body cooling automatic control system. A track is paved on one side of a cement kiln, a transmission device is installed on a small car frame where a fan is arranged, and the transmission device is mainly used for driving the fan to move freely and parallelly on the track by driving wheels. A kiln body infrared scanner system communicates with a computer control system which reads kiln body temperature alarm signals and over-temperature positions in the kiln body infrared scanner system, and through internal calculation, output signals control input quantity and cooling position of the fan so that the effect of reducing surface temperature of a kiln body can be achieved. The system effectively avoids partial overheating of the kiln body, protects fireproof tiles on the inner wall of the kiln from falling, greatly reduces maintenance amount of the kiln body, improves yield of cement clinker, simultaneously saves energy, and reduces possible dangers caused by manual operation.
Description
Technical field
The present invention relates to a kind of cement plant and control system, refer more particularly to cement kiln cylindrical shell cooling automatic control system.
Background technology
In present dry-process cement rotary kiln was produced, the cooling of cylinder of rotary kiln was a kind of supplementary means in its precal cination technique, and the high velocity air that promptly when calcining cement clinker, produces with blower fan blows to kiln cylinder body, i.e. clinkering zone, and the hot-spot place reduces the temperature at this place.At present known by trolley frame, anti-downly take turns, kiln cylinder body cooling device that blower fan, air duct nozzle are formed, it is the employing manually-operated, cooling device is dragged to assigned address cools off; A plurality of blower fan cover type types of cooling of employing are also arranged, but the waste that can produce power consumption like this.Because the variability of the position that drum surface is overheated; Adopt the manually-operated cooling device to be prone to produce hysteresis quality, promptly can not promptly and accurately arrive the position that needs cooling, but also operating personnel are in the hazardous environment of high temperature; Therefore; Can cause coming off of kiln inwall refractory brick, both increase the maintenance capacity of kiln cylinder body, also reduce the quality and the output of clinker simultaneously.
Summary of the invention
The present invention is for solving a kind of cement kiln cylindrical shell cooling system that has transmission device, adopts intelligent automatic control that the problem that exists in the above-mentioned technology provides.
The present invention addresses the above problem the technical scheme that adopts to be:
Be equipped with track in cement kiln one side, this track is parallel with the kiln body, and the trolley frame at blower fan place is through its four wheels parallel rolling in orbit; On the trolley frame at blower fan place transmission device is installed, described transmission device is made up of motor, shaft coupling and decelerator, thereby the main effect of this transmission device is to drive free in orbit parallel the moving of blower fan through driving wheel.The quantity of blower fan is confirmed according to the scale of on-the-spot cement kiln.
Computer control system is introduced in the startup of blower fan and stop signal, the rotating signal of the wheel transmission mechanism of trolley frame is introduced computer control system; Kiln shell noctovisor scan instrument system and computer control system are communicated; Computer control system therefrom reads kiln shell heat alarm and overtemperature position; Through internal calculation; The input quantity and the cool position of output signal controlling blower fan, thus reach the effect that reduces the kiln cylinder body surface temperature.
Advantage that has of the present invention and good effect are: owing on the trolley frame at blower fan place, transmission device is installed; And kiln shell noctovisor scan instrument system and computer control system communicated, input quantity that then can intelligent control blower fan reaches cool position automatically and efficiently; Not only effectively prevent the hot-spot of kiln cylinder body; Protect kiln inwall refractory brick and it is come off, significantly reduced the maintenance capacity of kiln cylinder body, improved the output of clinker; Practiced thrift the energy simultaneously, reduced because of the issuable danger of manually-operated.
Description of drawings
The present invention further specifies below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the present invention controls system configuration figure.
Among the figure
1. blower fan 2. transmission devices 3. trolley frames 4. tracks 5 computer control systems
6. industrial switch 7. kiln shell temperature surface sweeping instrument systems 8. Programmable Logic Controller PLC.
The specific embodiment
In the drawings, be equipped with track 4 in cement kiln one side, this track 4 is parallel with the kiln body, blower fan 1 with certain fixed angle on trolley frame 3, trolley frame 3 through its four wheels can be on track 4 parallel rolling; Transmission device 2 is installed on trolley frame 3, and described transmission device 2 is made up of motor, shaft coupling and decelerator, thereby this transmission device 2 can drive blower fan 1 free parallel moving on track 4 through driving wheel.The quantity of blower fan 1 is confirmed according to the scale of on-the-spot cement kiln.
The startup of blower fan 1 and stop signal are introduced computer control system 5 through Programmable Logic Controller PLC8, the motor positive and inverse signal of the wheel drive 2 of trolley frame 3 is introduced computer control system 5; Kiln shell noctovisor scan instrument system 7 and computer control system 5 are communicated; Computer control system 5 therefrom reads kiln shell heat alarm and overtemperature position; Through internal calculation; The input quantity and the cool position of signal output control blower fan 1, thus reach the effect that reduces the kiln cylinder body surface temperature.
