Abstract
The utility model discloses an automatic controlled electric heating boiler which is a hot water circulation circuit composed of a water pipeline, a heat using device, a water pump and a boiler tank body. An electric heater is arranged in the boiler tank body and connected with an automatic control circuit; a power supply power through the control circuit. The utility model has the advantages of high thermal efficiency, low energy consumption, no pollution, small occupation of land, few required staffs and high safety.
Description
The utility model belongs to heating installation, is specifically related to a kind of boilers heated electrically.
At present, domestic warming and hot-water supply still adopt coal-burning boiler or oil burning boiler technology.Above-mentioned technology be the heat that produces of coal and oil through tubular heat exchanger feedsupply heat, its thermal efficiency depends on the heat exchange efficiency of heat exchanger, the part heat has emitted by flue, not only wastes energy, and also atmosphere is produced and pollutes.In addition, also have storage of fuels to take up an area of big, many deficiencies such as need are many with personnel, heat cost height.
The purpose of this utility model provides a kind of thermal efficiency height, low, the free of contamination automatic control boilers heated electrically of energy consumption.
For achieving the above object, the solution that adopts of the utility model is: control boilers heated electrically automatically by water lines, form hot water circulation loop with hot facility, water pump and boiler tank body.In the boiler tank body electric heater is housed, electric heater is connected to automatic control circuit, and power supply is powered through control circuit.
The utility model is a heat-carrying agent with water still, and is the heat supply energy with the electricity.Because the heat of electricity conversion is all supplied with water, no heat energy loss does not have three waste discharge again, does not pollute.Also have simultaneously simple in structure, easy to operate, take up an area of less, characteristics such as operating personnel are few, safe and reliable, easy to maintenance, service life is long, applied widely.
Further specify structure of the present utility model below in conjunction with drawings and embodiments.
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of boiler tank body;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the electrical schematic diagram of control circuit;
Fig. 5 is the structural representation of the utility model embodiment 2.
Boilers heated electrically is formed hot water circulation loop by water lines 1, radiator 2, water pump 6 and boiler tank body 7; Constitute the electrical heating part of boiler by electrothermal tube 11, control circuit 8, thermometer 3 and temperature detect switch (TDS) 9.In embodiment 1, boiler tank body 7 is as a whole, several electrothermal tubes of evenly arranging 11 are arranged in the tank body 7, and electrothermal tube 11 is to be inserted in the tank body 7 by the insulation base 14 that embeds on tank body 7 tank skins, in the tank body outside that is embedded with base 14 zones patchboard guard shield 15 is arranged.The interface and the delivery port 16 of jointing temp table 3, Pressure gauge 4, safety valve 5 are arranged respectively above the tank body 7, base 18 is arranged below, discharging hole 12 and water inlet 17, the water pipeline 1 in delivery port 16 and water inlet 17 and the hot water circulation loop links.In the control circuit schematic diagram of Fig. 4, the 19th, isolating switch, the 20th, current transformer, the 21st, A.C. contactor, the 22nd, pump motor, the 11st, electric heater, the 23rd, voltmeter, the 24th, ammeter, the 25th, manual, automatic change-over, the 9th, temperature detect switch (TDS), the 26th, contactor solenoid, the 27th, firing switch, the 28th, often open, normally closed contact, the 29th, red green indicator lamp.Three phase mains is through A.C. contactor 21 water pump motors 22 and electric heater 11 in the main circuit, in the control circuit power firestreak through manually, automatic change-over 25, temperature detect switch (TDS) 9, contactor coil 26, firing switch 27, often open, normally closed contact 28, red green indicator lamp 29 are connected wires zero line.In embodiment 2, the heating tank body 7 of one group of series connection is arranged, in each heating tank body one group of electric heater 11 is arranged.The course of work of the present utility model is, at first hot water circulation loop is filled with water by running water inlet valve 10, close then into penstock 10, send electricity to give heater 11 by control circuit 8, after water in the boiler tank body 7 reached uniform temperature, starting water pump 6 was after reaching to fixed temperature, by temperature detect switch (TDS) 9 control heating automatically, keep water temperature.For guaranteeing safety, tank body 7 is provided with temperature-detecting device 3, Pressure gauge 4, safety valve 5, and water pipeline 1 is provided with atmospheric valve 13.Temperature-detecting device 3 is connected with temperature detect switch (TDS) 9, and the highest water temperature of temperature detect switch (TDS) 9 restrictions is no more than 90 ℃, so can not produce vapour pressure, guarantees security of operation.
