Description
Technical field
The utility model relates to one and lands cast-iron boiler, is specifically related to a kind of built-in anti-dry burning device landing cast-iron boiler.
Background technology
At present, the cast-iron boiler that lands is applied to gerotor type system more.During installation, open tank is set at system primary side height point.Water tank need maintain water state, ensures to be full of water in boiler, prevents dry combustion method.This anti-dry mode depends on system, if boiler applications is when pressure bearing system, need rethink anti-dry; In this mode, if open tank moisturizing not in time, time also anhydrous in boiler, system still can be burnt heating, therefore there is the hidden danger of boiler dry combustion method; For avoiding system lack of water, need checking of special messenger's not timing, not intelligence.
Utility model content
The purpose of this utility model is to provide one automatically can to detect in boiler whether lack of water, and the device of the timely moisturizing anti-dry of reminding user, improves to land the safety in utilization of cast-iron boiler.
The utility model discloses a kind of anti-dry burning device of console mode cast-iron boiler, be connected with the outlet pipe of console mode cast-iron boiler cast-iron stove sheet highest point, comprise water-level probe, wire, controller and ground wire thereof, the through hole running through its tube wall is offered in the upside of outlet pipe, water-level probe is connected in this through hole, the inside and outside end of outlet pipe is stretched into by wire connection controller in its inner, and the ground wire of controller is connected with boiler body.
Described water-level probe comprises metal probe and 95 porcelain bushings, the shape of metal probe is L-type, 95 porcelain bushings are covered in outside the vertical section of metal probe, arrange resistant to elevated temperatures insulated enclosure circle or apply resistant to elevated temperatures fluid sealant between the through hole on the outer wall of 95 porcelain bushings and described outlet pipe.
The vertical section of described metal probe has the support ring making described 95 earthenware location, the endoporus sidewall of 95 earthenwares has corresponding scrobicular ring, has insulating washer between the two ends of support ring and scrobicular ring.
The vertical section outer end of described metal probe and described wire bonds, weld is positioned at described 95 porcelain bushings.
Water-level probe of the present utility model is connected on the outlet pipe of console mode cast-iron boiler, and the inner of its metal probe is stretched in outlet pipe.When being full of water in boiler, metal probe contacts with water and by water and body of heater and ground conductive, controller default system has water, and boiler can normal combustion heating; When metal probe be in vacant state do not contact water time, controller default system lack of water, locking system also sounds the alarm, the timely moisturizing of reminding user, after moisturizing completes, controller deactivation system lock, boiler recover normal operating conditions.The anti-dry mode in the past that overcomes depends on the limitation of system, adopts single needle to detect and is built in boiler internal, and reduce to install and take up an area, improve the flexibility of boiler erection, the detection control accessible site of water level is in the control system of boiler.Completely avoid the appearance of boiler dry combustion method phenomenon, improve safety in utilization.
Anti-dry burning device is arranged at boiler internal in addition, and normal-pressure boiler and bearing boiler are all applicable.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model discloses a kind of built-in anti-dry burning device of console mode cast-iron boiler, be connected with the outlet pipe 5 of console mode cast-iron boiler cast-iron stove sheet highest point, comprise water-level probe 1, wire 2, controller 3 and ground wire 4 thereof, the through hole running through its tube wall is offered in the upside of outlet pipe 5, water-level probe 1 is connected in this through hole, and the inside and outside end of outlet pipe 5 is stretched into by wire 2 connection control device 3 in its inner, and the ground wire of controller 3 is connected to the outer wall of outlet pipe 5.
Water-level probe 1 comprises metal probe 11 and 95 porcelain bushing 12, the shape of metal probe 11 is L-type, 95 porcelain bushings 12 are covered in outside the vertical section of metal probe 11, arrange resistant to elevated temperatures insulated enclosure circle or apply resistant to elevated temperatures electric insulating sealant between the through hole on the outer wall of 95 porcelain bushings 12 and outlet pipe 5.
The vertical section of metal probe 11 there is the endoporus sidewall of support ring 13,95 porcelain bushing 12 that 95 porcelain bushings 12 are located have corresponding scrobicular ring, between the two ends of support ring 13 and scrobicular ring, have packing ring 14.
The vertical section outer end of metal probe 11 is welded with wire 2, and weld is positioned at 95 porcelain bushings 12.
Water-level probe of the present utility model is connected on the outlet pipe of console mode cast-iron boiler, and the inner of its metal probe is stretched in outlet pipe.When being full of water in boiler, metal probe contacts with water and by water and body of heater and ground conductive, controller default system has water, and boiler can normal combustion heating; When metal probe be in vacant state do not contact water time, controller default system lack of water, locking system also sounds the alarm, the timely moisturizing of reminding user, after moisturizing completes, controller deactivation system lock, boiler recover normal operating conditions.The anti-dry mode in the past that overcomes depends on the limitation of system, adopts single needle to detect and is built in boiler internal, and reduce to install and take up an area, improve the flexibility of boiler erection, the detection control accessible site of water level is in the control system of boiler.Completely avoid the appearance of boiler dry combustion method phenomenon, improve safety in utilization.
Anti-dry burning device is arranged at boiler internal in addition, and normal-pressure boiler and bearing boiler are all applicable.
As shown in Figure 3, one end of resistance R1 is connected with the pin VCC of single-chip microcomputer IC1 and positive source, and any one I/O mouth (herein called after IN1) and the metal probe 11 of the other end and single-chip microcomputer IC1 are connected; Metal probe 11 is placed in outlet pipe 5, to be separated do not contact by 95 porcelain bushings 12 with outlet pipe 5; The pin GND common ground of outlet pipe 5 and single-chip microcomputer IC1.Under exsiccosis, by resistance R1, IN1 is forced to be set to high level; Under having water (namely metal probe 11 partly or entirely enters in water) state, utilize the electric conductivity of impure water, by metal probe 11, aqueous medium and outlet pipe 5, make IN1 and ground wire realize conducting, IN1 is pulled to low level.According to low and high level Cleaning Principle, single-chip microcomputer reads the level state of IN1 in real time: if high level, is exsiccosis; If low level, then for there being water state.
