Abstract
The utility model relates to an electric heater for heating of an agriculture shed, belonging to the technical field of agricultural equipment. The electric heater is characterized in that an upper metal cooling body with a cavity and a lower metal cooling body with a cavity are stacked and fixed, wherein the interlayer part is provided with a through hole; the upper metal cooling body is provided with a heat-conducting medium oil intake hole; a metal heat exchange tube is across and airtightly fixed in the lower metal cooling body; two ends of the metal exchange tube are respectively communicated with a water inlet and a water outlet; the cooling bodies are filled with heat-conducting medium oil, and the metal exchange tube is filled with circulating water; the top of a heating body is provided with a water feeding port; a heating resistor stick is fixed in the heating body; and the upper part and the lower part of the heating body are respectively provided with a circulating water return port and a circulating water outlet. The electric heater disclosed by the utility model has the beneficial effects of having no pollution to environment, saving the labor cost as well as investment and maintenance operating cost of a boiler and facilities, improving the thermal efficiency and reducing the vegetable or flower production cost of the shed; and by taking coal as an energy source for example, the electric heater can save the production cost by more than 30%.
Description
Technical field
The utility model belongs to the farm equipment technical field.
Background technology
At present, in agriculture vegetables and flower planting process, low temperature all uses the plastic tunnel plantation during winter; But need heating in the booth, generally adopt burning coal heating means, need artificial and boiler facility for improving temperature of shed; Because the coal energy cost is higher, directly cause heating cost high simultaneously.
Summary of the invention
The purpose of the utility model is: a kind of agricultural booth heating electric heater is provided, and it can be the booth heating efficiently, at low cost.
The technical scheme of the utility model: have on the cavity, following heat dissipation metal body stack is fixing, and the interlayer of stack partly has through hole; On last heat dissipation metal body, have heat-conducting medium oil fuel feed hole; Crossing the airtight metal heat exchanger tube that is fixed with in the heat dissipation metal body down, metal heat exchanger tube two ends are communicated with water inlet and delivery port respectively, on cavity; Fill oily heat-conducting medium oil in the following heat dissipation metal body, in the metal heat exchanger tube, be filled with cycle water.
Be provided with the filler at the calandria top, be fixed with the heating resistor rod in the calandria, on the calandria, following two parts do not have and loop back the mouth of a river and circulating outlet.
The beneficial effect of the utility model is: environmentally safe; Saved labour cost; Saved the investment of boiler and facility and safeguarded running cost, improved the thermal efficiency, reduced booth and produced vegetables or flowers cost; To use coal to be example as the energy, the utility model can save production cost more than 30%.
Description of drawings
Fig. 1 is that structure chart cuts open in the utility model radiator office;
Fig. 2 is the utility model radiator A--A cutaway view;
Fig. 3 is the utility model calandria structure chart.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in the figure, the 1st, radiator, the 2nd, link, the 3rd, heat-conducting medium oil fuel feed hole, the 4th, upper and lower heat dissipation metal body interlayer, the 5th, interlayer through hole, the 6th, heat-conducting medium oil, the 7th, metal heat exchanger tube, the 8th, water inlet, the 9th, delivery port; The 10th, calandria, the 11st, filler, the 12nd, heating resistor rod, the 13rd loops back the mouth of a river, the 14th, circulating outlet, the 15th, cycle water, the 16th, temperature detect switch (TDS).
Have on cavity rectangular, following heat dissipation metal body stack is fixing, and the interlayer 4 between the upper and lower heat dissipation metal body has interlayer through hole 5; So that heat-conducting medium oil 6 flows in radiator; Metal heat exchanger tube 7 passes across down the heat dissipation metal body, metal heat exchanger tube 7 through water inlet 8 and delivery port 9 and calandria 10 circulating outlet 14 and loop back the mouth of a river 13 and be communicated with, hot water is circulated between calandria 10 and radiator 1; Accelerate to flow for impelling hot water; Also can between the pipeline of water inlet 8 and circulating outlet 14, add a water pump, can set in advance, realize regulation and control through temperature detect switch (TDS) 16 to canopy temperature; Each calandria 10 can drive several groups or tens groups of radiators 1, and each radiator 1 serial connection connection reaches whole circular.
