Abstract
The utility model provides a safety monitoring system for on living beings heating stove, its characterized in that: including current transformer, relay, power one, power two and wire, current transformer, relay and power one pass through the wire series connection, current transformer passes through the wire electricity with the live wire of water pump or exhaust fan on the living beings heating stove and is connected, whether current transformer detection circuitry has the current change, relay, power two pass through the wire with the pay-off motor on the living beings heating stove and form series circuit. The utility model provides a whether normal behavior's of exhaust fan or water pump safety monitoring system for on living beings heating stove is judged to the electric current that detects exhaust fan or water pump through independent external current transformer detection device.
Description
Technical Field
The utility model relates to a living beings heating stove technical field especially relates to a safety monitoring system for on living beings heating stove.
Background
Biomass heating furnaces (wood-fired particle furnaces) are roughly divided into two main types at present, and one type is a heating mode that a warm air furnace burns wood particles, cold air around the heating furnace is heated, and forced convection is carried out through a fan. The other type is a water heating furnace, which takes hot water as a heating medium, is connected with a radiator or a ground heating pipe through a pipeline and adopts a heat supply mode of forced circulation of a water pump.
No matter the air heating stove or the water heating stove, the built-in forced-exhaust fan needs to forcibly exhaust the flue gas combusted in the heating stove, and simultaneously introduces the air participating in combustion so as to ensure that the interior of the hearth is in a negative pressure state. When the forced-ventilated fan fails, the biomass heating furnace always automatically feeds materials, wood particles are not completely combusted, a large amount of smoke is generated in the hearth and cannot be discharged in time, the pressure in the hearth rises and is in positive pressure, and therefore the smoke overflows. When the circulating water pump of the water heating furnace breaks down, the water in the water tank of the water heating furnace does not circulate any more and rises all the time, and a large amount of gas is generated to impact the water tank to cause leakage. Therefore, the automatic feeding must be cut off immediately when the circulating water pump fails, so that the water temperature does not rise continuously and is always within a safe temperature range.
SUMMERY OF THE UTILITY MODEL
Based on the problem, the utility model aims to provide a whether normal behavior's of exhaust fan or water pump safety monitoring system for on living beings heating stove is judged to the electric current that detects exhaust fan or water pump through independent external current transformer detection device.
Aiming at the problems, the following technical scheme is provided: a safety monitoring system for biomass heating stove which characterized in that: including current transformer, relay, power one, power two and wire, current transformer, relay and power one pass through the wire series connection, current transformer passes through the wire electricity with the live wire of water pump or exhaust fan on the living beings heating stove and is connected, relay, power two pass through the wire with the pay-off motor on the living beings heating stove and form series circuit.
The utility model has the advantages that:
the safety monitoring system has the function of immediately cutting off automatic feeding when the forced exhaust fan fails, so that fuel supply is avoided, and a large amount of smoke is not accumulated in the hearth so as not to overflow; or the automatic feeding is immediately cut off when the circulating water pump fails, so that the water temperature cannot be continuously increased and is always within a safe temperature range.
When the safety monitoring system works, a power supply is turned on, when the circulating water pump or the forced exhaust fan works, the current transformer detects that a circuit has current change, a relay connected with the feeding motor is attracted, and the circuit where the feeding motor is located is normally connected; when the water pump or the forced exhaust fan breaks down and is disconnected, the current transformer detects that no current changes exist in the circuit, the relay connected with the feeding motor is disconnected, and the circuit where the feeding motor is located stops working when the circuit is disconnected.
Drawings
Fig. 1 is a schematic structural diagram of a safety monitoring system in an embodiment of the present invention;
the figure shows schematically: 1-a current transformer; 2-a relay; 3, a first power supply; 4, a second power supply; 5-a wire; 6-water pump or exhaust fan; 7-a feeding motor;
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in figure 1, a safety monitoring system for biomass heating stove, including current transformer 1, relay 2, power 3, power two 4 and wire 5, current transformer 1, relay 2 and power 3 pass through wire 5 series connection, current transformer 1 passes through wire 5 with the live wire of water pump or exhaust fan 6 on the biomass heating stove and is connected electrically, relay 2, power two 4 and the pay-off motor 7 on the biomass heating stove pass through wire 5 and form series circuit.
When the safety monitoring system works, the first power supply 3 is turned on, when the circulating water pump or the forced exhaust fan 6 works, the current transformer 1 detects that the circuit has current change, the relay 2 connected with the feeding motor 7 is attracted, and the circuit where the feeding motor 7 is located is normally connected; when the water pump or the forced exhaust fan 6 is disconnected due to faults, the current transformer 1 detects that no current changes exist in a circuit, the relay 2 connected with the feeding motor 7 is disconnected, and the circuit where the feeding motor 7 is located stops working when the circuit is disconnected.
The safety monitoring system immediately cuts off automatic feeding when the forced exhaust fan fails, so that fuel supply is avoided, and a large amount of smoke is not accumulated in the hearth to overflow; or the automatic feeding is immediately cut off when the circulating water pump fails, so that the water temperature cannot be continuously increased and is always within a safe temperature range.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations of the above assumption should also be regarded as the protection scope of the present invention.
