Description

The holding furnace heater

One, technical field

The utility model relates to the matching used aluminium liquid of a kind of heater of holding furnace, particularly air injection machine holding furnace heater.

Two, background technology

Traditional holding furnace heater (as shown in Figure 3-4) is made up of three Elemas 9,10,11, and wherein 9b, 10b, 11b three end Y shapes connect, and 9a, 10a, 11a are tightly connected with the power supply of holding furnace switch board output respectively and form the galvanic circle and heat.Because of single Elema can only bear 110V voltage, can not directly be connected with the supply voltage of 380V, between Elema and switch board power supply, must increase a dedicated transformer and change voltage swing, transformer rated power is 40KVA.There is following defective in this heater:

1. every transformer amount of money to produce 150 insulation furnace gauges every year, needs 1,650,000 yuan about 1.1 ten thousand yuan, increases cost of investment, and transformer rated power is 40KVA simultaneously, and user in use consumed power is bigger;

2. noise is bigger in the course of the work for transformer, influences working environment;

3. Elema in use can constantly wear out, and resistance increases gradually, and power diminishes gradually, by transformer control voltage inconvenience;

4. it is bigger that single Elema bears electric heating, easily oxidation, and service life is short.

Three, utility model content

Main purpose of the present utility model is, overcome the defective that above-mentioned existing holding furnace heater exists, and provide a kind of heater of new structure, technical problem underlying to be solved is to improve the holding furnace heater, save the holding furnace manufacturing cost, prolong the service life of heating element heater, do not add thermal effect but do not influence holding furnace simultaneously.

The purpose of this utility model and to solve its subject matter be to adopt following technical scheme to realize.According to a kind of holding furnace heater that the utility model proposes, comprise Elema 1,2,3,4,5,6, braided wire 7, Elema fixed cover 12, earthenware 13, described Elema 1,2,3,4,5,6 two ends are with earthenware 13 respectively, and be fixed on body of heater 8 tops with described Elema fixed cover 12, described Elema 1b and 2b, 3b and 4b, 5b and 6b are connected in series by described braided wire 7, described Elema 2a, 4a, 6a connects by described braided wire 7Y shape, 1a, 3a, 5a is connected with the control power supply by described braided wire 7 respectively, forms the galvanic circle.

The utility model is not influencing under the prerequisite that adds thermal effect, in each installation room, increase an Elema, do not need to connect again transformer, just can directly be connected, save cost of investment, increase economic efficiency with the switch board supply voltage, and make the employee convenient in operating process, reduce noise simultaneously, improve working environment, also reach energy-saving effect.In addition, two Elemas are connected in series, and have reduced the average caloric value of Elema, improve Elema service life.

Four, description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model structural representation;

Fig. 2: the utility model circuit theory diagrams;

Fig. 3: the structural representation before the utility model does not improve;

Fig. 4: the circuit theory diagrams before the utility model does not improve;

1,2,3,4,5,6-Elema among the figure:; 7-braided wire; 8-body of heater; 12-Elema fixed cover; 13-earthenware.

Five, embodiment

As shown in Figure 1, the two ends of Elema 1,2,3,4,5,6 are with earthenware 13 respectively, and be fixed on body of heater 8 tops, Elema 1b and 2b, 3b and 4b with Elema fixed cover 12,5b and 6b are connected in series by braided wire 7, Elema 2a, 4a, 6a connect by braided wire 7Y shape respectively, and 1a, 3a, 5a are connected with the control power supply by braided wire 7 respectively, form the galvanic circle, when the control power connection, the heater operate as normal.By enforcement of the present utility model, reduced the manufacturing cost of holding furnace, prolong heating element heater service life, save energy consumption.

The utility model is novel, and effect is obvious, and is simple in structure, implements easily.

Claims (1)

1. holding furnace heater, it is characterized in that: comprise Elema (1,2,3,4,5,6), braided wire (7), Elema fixed cover (12), earthenware (13), described Elema (1,2,3,4,5,6) two ends are with earthenware (13) respectively, and be fixed on body of heater (8) top with described Elema fixed cover (12), described Elema (1b) with (2b), (3b) with (4b), (5b) Yu (6b) be connected in series by described braided wire (7), described Elema (2a), (4a), (6a) connect by described braided wire (7) Y shape, (1a), (3a), (5a) be connected with the control power supply by described braided wire (7) respectively, form the galvanic circle.
