Background technology
At present, the steam sootblower for industrial heating furnace convection cell, convection tube and Industrial Boiler boiler tube is to adopt comparatively advanced overheating steam blowing ash device.Such soot blower is that the frame for movement by the speed-changing rotation gear becomes driving mechanism, by the conducting of director circle dish and travel switch control steam, ejects high-temperature high-pressure overheat steam by sleeve type structure, realizes the ash that blows to convection bank etc.Its complex structure is prone to gas leakage between sleeve, reliability is low.The blowing pipe that whole circle rotates is all at ejection steam, and the convection tube of convection cell is only in the up and down both sides of blowing pipe, and the jet so that blowing pipe of whole circle is when going to horizontal position, and steam sprays to furnace wall becomes invalid injection, waste steam; The steam straight hole blows out, and it is low to blow grey efficient.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of intelligent control non-flexible synchronous soot blower system, cancelled the independent heating coil system of prior art, reduce the steam amount of expending, reduced the equipment use amount, realize its intelligent control, simple in structure, reliable, part is few, consume the few energy saving type synchronous telescopic soot blower of quantity of steam.
The technical scheme that realizes above-mentioned purpose is: the non-flexible synchronous soot blower system of a kind of intelligent control, it is characterized in that: comprise industrial furnace bindiny mechanism, blow grey magnetic valve, motor, motor support plate, blowing pipe, the blowing pipe tube connector, steam connection, heating coil flue gas leading and decelerator, describedly blow grey tube connector and be connected in the industrial furnace bindiny mechanism, blow and also be fixedly connected with travelling gear on the grey tube connector, the front end that blows grey tube connector is connected with blowing pipe, also be provided with the steam ozzle on the blowing pipe, the rear end of blowing grey tube connector is connected with the outlet of blowing grey magnetic valve, blows grey tube connector and is equipped with airtight and watertight padding with the outlet junction of blowing grey magnetic valve; Described motor support plate is installed on a side of industrial furnace bindiny mechanism, electric machine is on motor support plate, the output shaft of motor is connected with decelerator, be fixedly connected with driving gear on the output shaft of decelerator, travelling gear on driving gear and the blowing pipe forms gear pair, at travelling gear rotation sensor is installed, the rotation inducing receiver that is used with rotation sensor is installed in industrial furnace bindiny mechanism; Described steam connection is connected with the input port of blowing grey magnetic valve by flange, and thermocouple also is installed on the steam connection, and described heating coil flue gas leading is connected with steam connection, also is provided with the heating coil magnetic valve on the heating installation flue gas leading.
Rotation sensor of the present invention and rotation inducing receiver can be angular measure chi induction pieces.
Rotation sensor of the present invention and rotate inducing receiver and can be approach switch is separately installed with the transmitting terminal of approach switch in two different angles of travelling gear, and the receiving terminal of an approach switch is installed in industrial furnace bindiny mechanism.
The invention has the beneficial effects as follows: cancel independent heating coil system, can reduce the equipment use amount, reduce and take up an area, reduce controlled quentity controlled variable, minimizing potential safety hazard.
Reduce original electrical control cabinet system, reduce system cost.
Reduce steam consumption, reliability height, blow grey efficient height.
The soft control of intelligent automation, affected simple, low in energy consumption.
Have energy-conservationly, efficient, handled easily is installed, simple in structure, when having reduced worker and the advantage of materials'use amount.

The specific embodiment
Embodiment 1
As shown in Figure 1, the present invention mainly by industrial furnace bindiny mechanism 1, blow grey magnetic valve 2, motor 3, motor support plate 4, blowing pipe 5, blowing pipe tube connector 6, steam connection 7, heating coil flue gas leading 8 and decelerator 12 and form.
Blowing grey tube connector 6 is connected in the industrial furnace bindiny mechanism 1, blow on the grey tube connector 6 and also be fixedly connected with travelling gear 9, the front end that blows grey tube connector 6 is connected with blowing pipe 5, also have steam ozzle 10 on the blowing pipe 5, the rear end of blowing grey tube connector 6 is connected with the outlet of blowing grey magnetic valve 2, blows grey tube connector 6 and is equipped with airtight and watertight padding 11 with the outlet junction of blowing grey magnetic valve 2.
Motor support plate 4 is installed on a side of industrial furnace bindiny mechanism 1, motor 3 is installed on the motor support plate 4, the output shaft of motor 3 is connected with decelerator 12, be fixedly connected with driving gear 13 on the output shaft of decelerator 12,9 one-tenth gear pairs of driving gear set on driving gear 13 and the blowing pipe 5, at travelling gear 9 goniometer gage induction pieces 14 is installed, the receiving device 15 of the goniometer gage induction pieces that is used with goniometer gage induction pieces 14 is installed in industrial furnace bindiny mechanism 1.
Steam connection 7 is connected with the input port of blowing grey magnetic valve 2 by flange, and thermocouple 16 also is installed on the steam connection 7, and heating coil flue gas leading 8 is connected with steam connection 7, also is provided with heating coil magnetic valve 17 on the heating installation flue gas leading 8.
Embodiment 2
As shown in Figure 2, the structure of embodiment 2 is identical with embodiment 1, the receiving device 15 of goniometer gage induction pieces 14 and goniometer gage induction pieces adopts approach switch, be separately installed with the transmitting terminal 18 and 19 of approach switch in two different angles of travelling gear 9, the receiving terminal 20 of an approach switch is installed in industrial furnace bindiny mechanism 1.
The course of work of the present invention:
The ash beginning is blown by system, open heating coil magnetic valve 17, steam passes into the front pipe-line system of soot blower, enter heating coil discharge leader 8, heating coil discharge leader 8 access factory system gas recovery systems are realized recycling, reach setting-up time, thermocouple 16 detects the rising of pipe-line system temperature and reaches the pipeline serviceability temperature, stops heating coil.
As shown in Figure 1, embodiment one is the rotary grey process of blowing, at first open and blow grey magnetic valve 2 conducting steam soot blowings, blowing pipe 5 rotates under the drive of motor 2, when blowing pipe 5 rotations reach desired location, receiving device 15 output orders of goniometer gage induction pieces are given and are blown grey magnetic valve 2, blowing grey magnetic valve 2 closes and stops to blow ash, blowing pipe 5 continues to rotate to reach to blow grey position, blow grey magnetic valve 2 and open, reach when not needing to blow grey position when blowing pipe 2 rotates, receiving device 15 output orders of goniometer gage induction pieces are given and are blown grey magnetic valve 2, blow grey magnetic valve 2 and close, circulate to form with this and blow synchronously grey function.
As shown in Figure 2, embodiment two blows grey process for the swing rotary formula, when blowing pipe 5 turns to the position of transmitting terminal 18 of approach switch, motor 2 inverted machine power supplys, motor 2 counter-rotatings, blowing pipe 5 oppositely blows ash, when blowing pipe 5 turns to the position of transmitting terminal 19 of approach switch, motor 2 is just connecing motor power, and motor 2 forwards form and so forth and decide the angle rotary synchronous.
