Description

Intelligent temperature control roofing spray temperature control grain storage silo

Technical field

The utility model relates to silo grain storage control temperature storage control device field.

Background technology

At present, the grain storage of silo roofing water spray temperature control is one and suits measures to local conditions cost-effective practical technique.Because of it has small investment, easy and simple to handle, energy consumption is low, is convenient to management, but characteristics such as recycling rate of waterused height, and is generally applying domestic various places.Cooling water source is divided into running water circulation cooling, mountain spring water and well water sub-cooled three classes substantially; The spray control model of taking develops into by microcomputer timing and controls the batch (-type) spray automatically then by the round-the-clock spray of Artificial Control originally.And above no matter which kind of mode is quite big in the waste of the resource and the energy; And there is when the storehouse temperature is too high the stiff pattern of mechanization that system was but also moving when system did not but also start or the storehouse temperature suits.Be difficult to like this guarantee that the grain of storage is not subjected to the influence of external high temperature in summer.

Technology contents

The purpose of this utility model is exactly to provide intelligent temperature control roofing spray temperature control grain storage silo at the existing silo roofing water spray above-mentioned deficiency of temperature control grain storage mode, comprise silo 1, it also has shower 2, water pump 3, intelligent temperature controller 4 to form, and intelligent temperature controller is made up of temperature controller A, time relay KT, A.C. contactor KM, section breaker; Shower 2 is installed on the silo 1 roof face, shower 1 communicates with the delivery port of water pump 2, the thermosensitive probe A-1 of temperature controller A is placed in the silo, thermosensitive probe A-1 is transferred to temperature controller A with the temperature signal of impression, temperature controller A sends control signal and gives time relay KT, time relay KT is electrically connected with A.C. contactor KM, and A.C. contactor KM is electrically connected with section breaker, the motor of section breaker water pump 3.Shower 2 is made up of aqueduct and one group of shower nozzle, and aqueduct is installed on the silo 1 roof face, has one group of water jet on the aqueduct, and one group of shower nozzle is installed in aqueduct water jet place.

The utility model has the advantages that: 1, early summer to autumn end is utilized the water supply spray system that roofing is installed, and in conjunction with the temperature control delay circuit system of thermistor probe control in the silo, controls water automatically and sprays or the shutdown system operation at roofing.Make to remain default temperature value in the storehouse, and reach grain low temperature, guarantee the quality, the purpose of fresh-keeping storage.Both reduce energy waste, saved expenses again, saved man-hour.2, be 0.16% by its fatty acid value increasing degree of grain in this silo of evidence, be lower than fatty acid value increasing degree (0.22%) in the common silo.Show that it has realized the quality increment.3, because the grain stack temperature is constant, shortens aeration-cooling cycle and time, thereby also reduced the dry matter consumption and the moisture decrement of grain, can obtain considerable economic.4, constant low temperature can suppress insect pest effectively.Also alleviated simultaneously because of repeating the stifling expenses of bringing and, meeting the demand for development of green grain storage the pollution of grain.

Embodiment

Concrete implement silo be No. 2 storehouses of Yuling State Grain Storehouse, Jingmen City, Hubei (length * wide * height=52m * 18m * 6m), grain storage is a late long grain nonglutinous rice, airtight storage, grain is piled high 4.5m, average moisture 13.2% contains and mixes 0.6%, quantity 2543t.Adopt well water to do the water source, pump power is 2kW, and lift is 40m; Shower nozzle has 9 in rocking arm shower nozzle (7 sprinkling irrigation diameters are 18m, and 2 sprinkling irrigation diameters are 10m) and 40 in lotus leaf shower nozzle (the sprinkling irrigation diameter is 1m); The every interval 1m of PVC aqueduct installs 1 lotus leaf shower nozzle, and every 5m adorns the Yuanan ZH type rocking arm shower nozzle.The thermosensitive probe of temperature controller is fixed on arch bar following about 40cm place in roof in the test cabin; Thermosensitive probe is transferred to temperature controller with the temperature signal of impression, and temperature controller sends control signal and gives the time relay, and the time relay is electrically connected with A.C. contactor, and A.C. contactor is electrically connected with section breaker, the motor of section breaker water pump.

During use, set temperature controller temperature-control range summer generally at 25 ℃, the time relay is set to move 5 minutes cyclic extensions program of 3 minutes time delay intervals, to reach object of energy saving.Go into the mid-autumn in the Summer Solstice, when The hot sun is high in the sky, when temperature is higher, connect power supply, to dirty, the water of Z H type rocking arm shower nozzle ejection can be poured in the diameter 18m Anywhere along tile for timing water-feeding, the water of lotus leaf shower nozzle ejection.When grain temperature is higher than 25 ℃, temperature controller is passed to the time relay with enabling signal, the time relay is passed to A.C. contactor with signal, A.C. contactor is passed to section breaker with signal, section breaker starts pump working, and when water pump operation after 3 minutes, the time relay is passed to section breaker with cut-off signal by A.C. contactor, section breaker disconnects pump power, and water pump quits work.After pump power quit work 5 minutes, the time relay was passed to section breaker with enabling signal by A.C. contactor again, and section breaker starts pump power, and water pump is started working.Circulation so repeatedly, when grain temperature is lower than 25 ℃, temperature controller will start cut-off signal and pass to section breaker by the time relay and A.C. contactor, and section breaker starts pump working, disconnects pump power, and water pump quits work.In concrete operations, also should regulate time relay delay time according to cooling-down effect, the control water spraying time makes it to reach optimum efficiency.
