The utility model is characterized in that an electric control case is arranged on upper part of the electrical heating chamber. An air inlet interface flange is arranged on left side of the electrical heating chamber and a discharge flange is arranged on right side of the electrical heating chamber. Exposed iron chrome-nickel alloy heating cord is adopted to heat inside the electrical heating chamber and is fixed to an electric porcelain column which is connected to a power supply. The ozone mixing chamber is equipped with an enclosure with an ozone intake on top of the ozone mixing chamber. An inlet flange is arranged on left side of the ozone mixing chamber and a discharge flange is arranged on right side. A temperature sensor probe is equipped in the ozone mixing chamber. The device is simple in structure, usable, convenient to be maintained, movable, is low in cost, and high in efficiency, can be used as both an automatic control electric heater for exclusive use of large mobile grain depots and a subsidiary heating device on general granary ventilators.
Description
Technical field
The device that the utility model relates to use in a kind of large-scale mobile grain during procedure of storing grain aeration drying system a kind of efficient, moves, can control heating.
Background technology
The auxiliary heating of drying generator is exactly by the suitable heat of interpolation, and the drying medium temperature is improved, and purpose is the condition that an approximate summer or early autumn are provided to drying generator, makes drying generator not limited by air conditions, finishes dry run faster and better.Drop to 18% when following when grain moisture content in the silo dry run, especially winter, spring, cold and moist weather is unfavorable for drying, further drop to moisture below the safe storage line and will need considerable time.Adopt auxiliary heating can shorten required time and minimizing expenses.
The assisted heating device of market sale now mainly contains coal-fired heater, fuel oil (gas) heater and electric heater.Coal-fired heater and fuel oil (gas) heater volume is huge, it is big to pollute, cost is high, move inconvenience, control is difficult can't be installed in portable with regard in the system of storehouse; And in the fixed force ventilation of the silo that electrical heating is mainly used in, move, control and all compare difficulty, be difficult to the portable drying generator of adaptation system, therefore need produce a kind of removable, low cost, has the ozone hybrid chamber, can be used for the assisted heating device of large-scale mobile drying generator system easy to maintenance, high efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of silo Special Automatic control electric heater, this apparatus structure is simple, easy to use, easy to maintenance, removable, cost is low, efficient is high, can be used for the Special Automatic control electric heater of large-scale mobile grain depot, also can be used for the assisted heating device on the general silo ventilation equipment.
The Special Automatic control electric heater of a kind of silo, form by electrical heating chamber and ozone hybrid chamber two parts, it is characterized in that electric control box being arranged, support by supporting leg below the electrical heating chamber, but front, electrical heating chamber is the door of folding on top, electrical heating chamber, above the door door lock is arranged, left side, electrical heating chamber is the air intake flange, and the right side is an outlet(discharge) flange, and the fe-cr-ni alloy heating wire of bareing is equipped with in inside, electrical heating chamber, heating wire is fixed on the insulation porcelain knob, and the electrothermic wire insulation binding post is received on the power supply; Described ozone hybrid chamber has a shell, and ozone hybrid chamber upper end is the ozone inlet, and ozone hybrid chamber left side is an inlet flange, and the right side is an outlet(discharge) flange, in the ozone hybrid chamber temperature sensor probe is housed.
Be connected with screw between the inlet flange in ozone hybrid chamber left side and the outlet(discharge) flange on right side, electrical heating chamber.
The fe-cr-ni alloy heating wire adopts star connection.
The electrical heating chamber is the square electrical heating chamber of a tape insulation heat-insulation layer, and insulation material is housed in heat-insulation layer.
Of the present utility model have thermal efficiency height, simple in structure, have the ozone hybrid chamber concurrently, can supportingly be used for the three-dimensional drying generator of large-scale mobile system.
Description of drawings
Fig. 1 the utility model electric heater external structure schematic diagram.
Fig. 2 the utility model electric heater internal structure schematic diagram.
Fig. 3 the utility model electric heater control system schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, the utility model is made up of two parts: electrical heating chamber 18 and ozone hybrid chamber 13, but front, electrical heating chamber is the door 6 of folding, and door lock 8 is arranged above, can be easy to open, and is convenient to maintenance; Top is electric control box 1, is supported by supporting leg 7 below; The left side is an air intake flange 5, and the right side is an outlet(discharge) flange 9.
The ozone hybrid chamber has a shell 11, and the upper end is an ozone inlet 3, and drying medium and ozone are sent into the grain heap and carried out drying and remove mould after this mixes, and the left side is an inlet flange 10, is connected with heater outlet flange 9 usefulness screws 2; The right side is an outlet(discharge) flange 4.
The fe-cr-ni alloy heating wire 14 of bareing is equipped with in electric heater of the present utility model inside, heating wire is fixed on the insulation porcelain knob 16, electrothermic wire insulation binding post 12 is received on the power supply, this figure only draw one mutually the electricity heater strip, the heater strip that three-phase electricity is arranged in the reality adds insulation material 15, temperature sensor probe 17 feedback heater export temperature in the middle of ectonexine, when temperature is too high, stop heating, see accompanying drawing 2.
As shown in Figure 3, the utility model electric heater adopts three-phase four-wire power supply mode, L1, L2, L3
Three-phase 380V, N are zero line.HK is an automatic air circuit breaker, and FU1 is the major loop fuse, and KM is the A.C. contactor of control electric heater ZW,
The automatic air circuit breaker HK that closes, the control loop electric current is through control fuse FU2, and power supply indicator XD1 lights; Temperature controller TK serves electricity, shows current electric heater outlet temperature; Press starting button SQ2, A.C. contactor KM gets electric adhesive, and electric heater ZW begins heating (the heater heating wire adopts star connection), the KM self-insurance, and heater relay indicating light XD2 lights.
Press stop button SQ1, A.C. contactor KM dead electricity, the major loop contact disconnects, and heater quits work, and the KM auxiliary contact disconnect and lose self-insurance, and relay indicating light extinguishes.
When heater was worked, when outlet temperature was higher than temperature controller TK setting value, the auxiliary normally-closed contact of TK disconnected, and makes contactor KM dead electricity, cuts off the power supply of heater, and heater is quit work, and plays a protective role.
