Abstract
The utility model relates to an automatic electric heater controlled by a micro computer. An electric heat exchanger is made into small barrel type electric heat exchangers which can be installed in series connection and parallel connection. A logic circuit of an original relay is replaced by an industrial programmable controller, and a variable frequency speed regulator is added, so that the batch production is controlled by the electric heat exchanger. The utility model has the advantages of low cost and more functions.
Description
The utility model belongs to the improvement of electric heating equipment.
Electric heating equipment with pollution-free, noiselessness, unmanned, easy to maintenance, expense is low, advantage such as easy to install is subjected to people's welcome very much.Chinese patent (CNZL88215841.1) has designed a kind of full-automatic electric heating heating plant, mainly contain electrical heat exchanger, electrical control cabinet, heating therrmodynamic system three parts composition, it has following shortcoming: the one, and its heat exchanger is a big body of heater of monotubular formula, then need to carry out one-piece design and manufacture as manufacturer production according to user's requirement difference, make production cost improve like this, be unfavorable for producing in batches; The 2nd, the control protection electric circuit in its electrical control cubicles adopts relay logic control protection circuit; it also needs artificial the input when the increase and decrease of electrothermal tube; really do not reach full-automatic; and structure is numerous and diverse, volume is big, defencive function is few, fault is more, these drawbacks limit the application of this electric heating equipment.
The purpose of this utility model is, this electric heating equipment is improved, to overcome above-mentioned shortcoming.
Of the present utility model being characterised in that, electrical heat exchanger is made into the plant with tubular electrical heat exchanger that can make up installation, in each little tube three electrothermal tubes are installed, can combine several plant with tubular electrical heat exchangers with series connection or parallel connection that recirculated water is imported and exported; In electrical control cabinet, replace former relay logic circuit, and increased variable-frequency governor with industrial Programmable Logic Controller.
By as can be seen above-mentioned, size according to user's heating area, with a plant with tubular electrical heat exchanger is elementary cell, can combine several electrical heat exchanger connection in series-parallel, make the electrical heat exchanger typing to produce in batches like this, not only reduced cost, and in use keep in repair, replacing, dismounting all become and be easy to; Substitute former relay logic circuit with industrial Programmable Logic Controller, have not only that volume is little, function is strong, reliable operation, advantage that fault rate is low, and can also increase the function of self-clocking, automatic trouble diagnosis, when the increase and decrease of electrothermal tube, need not artificial input, and increased the function of frequency control automatic constant pressure moisturizing, realized the level pressure circulation of heating system, need not to replenish, saved equipment investment with special equipment level pressure such as air pressure tanks.
Accompanying drawing 1 is the structural representation of the plant with tubular electrical heat exchanger of the designed electric heating equipment of the utility model, and 1 is heat-insulation layer among the figure, and 2 is cylindrical shell, and 3 is electrothermal tube, and 4 is intake-outlet, and 5 is end cap, and 6 is protective cover.Accompanying drawing 2 is the instance graph of a circuit connection principle in the electrical control cabinet, accompanying drawing 3 is for adopting the connection principle instance graph of the Japanese fuji NB1-P24 of company type industry Programmable Logic Controller (PLC), and accompanying drawing 4 is for adopting the connection principle instance graph of the Japanese fuji FVR-G75 of company type variable-frequency governor.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, designed electrical heat exchanger can be made into the plant with tubular of φ 300, in each little tube three electrothermal tubes are installed, if select the electrothermal tube of 10KW for use, then the aggregate power of each little tube is 30KW, can supply 50 square metres of heating in the area, Xi'an, so can be according to the demand of user heating area, several little tube series connection or combination in parallel are installed, at most can 1 tens little tubes be combined.Circuit in the electrical control cabinet and the basically identical of CNZL88215841.1, accompanying drawing 2 has provided the wiring example, the wiring example of the secondary line in the electrical control cabinet is then provided by accompanying drawing 3 and accompanying drawing 4, Programmable Logic Controller in the secondary line and variable-frequency governor remove Japanese fuji company, also can select Mitsubishi for use, Sanyo, Siemens, Omron and homemade, the industry Programmable Logic Controller in use should be according to user's demand, required function and parameter are compiled into software, being input to computer with programmable device solidifies among the ROM, circulation is carried out, and these are easy to do to the professional who does automatic control or software.Heating hot-water heating system in the utility model with other do not change the part then all with CNZL88215841.1 in consistent, just repeat no more here.
