Abstract

The utility model provides an adjustable temp. And humidity preservation device for granary used to store the grain. The device uses a vacuum-pumping system driven by a vacuum pump to extract the humid gas in the grain hoarder and interpolate dry fresh air to adjust the temperature difference inside and outside the grain hoarder, decrease the water content of the grain and achieve the safe grain storing without turning over the grain hoarder and sunning. The vacuum-pumping system adopts a stop valve and a filter to make the vacuum pump and a suction device communicated together. The utility model has the advantages of convenient operation, low cost, few energy consumption and improving the effective grain storing area of the floor.

Description

Adjustable temp. and humidity preservation device for granary

The utility model provides a kind of granary that is used to store grain to fall wet thermoregulating fresh-keeping device.

At present, the grain that is stored in granary often adopts thermometric, observation, falls to store up, the way of airing, regulates and stores up internal-external temperature difference, reduces grain moisture content, in case the grain moldy metamorphism.But, this way of grain bin, airing, big, the many labor intensive of floor space, material resources, financial resources increase the grain storage cost.Methods such as seal up for safekeeping in the employing seabed that also has, cobalt 60 sterilizations store grain, but being subjected to condition limits, and are difficult for promoting.For the grain of high moisture content, available heat drying kiln reaches the purpose that reduces water content, but because the kiln temperature inequality often causes local coking of the grain that is dried or the not saturating local moisture content of drying higher.Also have a kind of ventilation storehouse that is used for reducing water content specially, because of cost height, energy consumption are big, required auxiliary conveying equipment is many, so still can not generally use.

The purpose of this utility model provides a kind of granary and falls wet thermoregulating fresh-keeping device, it can not only make grain without fall to store up, not airing can reach the purpose of falling wet temperature adjustment, and installation, easy and simple to handle, less energy consumption, reduction grain storage cost.

The purpose of this utility model is achieved in that the vacuum-pumping system that utilizes vavuum pump to drive, the wet gas of granary inside is extracted out, mend than dry live gas, to finish without the temperature difference inside and outside storing up, the water content that reduces grain, the task of safe grain storage are regulated in grain bin, not airing.This device comprises vavuum pump and is attached thereto logical vacuum-pumping system.This vacuum-pumping system adopts non-return valve and filter, vavuum pump and air extractor are communicated with, air extractor is coated by gauze and has the center exhaust tube of passage and the ring of bleeding is formed, and the pipe end of drawing of the exhaust tube and the ring of bleeding seals with seal or is connected with the non-return valve end with tube connector.Gauze can be made with anti-rust metal gauze or non-toxic plastic gauze.The center exhaust tube also can have the breather pipe that is radial arrangement.How much quantity of the air extractor of putting in each granary can determining according to actual grain storage amount.

Owing to adopt vacuum-pumping system directly the wet gas in the granary to be extracted out, mend fresh dry gas, reconciled and stored up the inside and outside temperature difference, reduced the water content of grain, so can not fall grain bin, not airing.Therefore, can save, reduce transporting equipment and workmen, reduce the grain storage cost, improve effective grain storage area in place because of falling loss and the funds spending that grain bin, airing cause.The condition that result wet, temperature adjustment also can destroy the microbial reproduction existence that grain itself carries falls in vacuum suction in addition, can prevent the grain moldy metamorphism.In traditional airing grain process, compositions such as the starch in the grain, protein, fat, sugar are caused damage easily by long-term ultraviolet ray irradiation, adopt this device can overcome above-mentioned defective, and the contained composition of grain is suffered a loss less, reach fresh-keeping purpose.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 3 is the structural representation of a kind of center of the utility model exhaust tube.

Fig. 4 is the vertical view of Fig. 3.

Describe concrete structure of the present utility model and operating position in detail according to Fig. 1～4.This device comprises that vavuum pump 10 and coupled logical vacuum-pumping system, this vacuum-pumping system adopt general non-return valve 8 and filter 9, are communicated with vavuum pump with air extractor.Air extractor bleed by center exhaust tube 1, centre that ring 2, outer ring bleed that the center exhaust tube 1 of passage is formed, had to ring 3 and the ring 2,3 of bleeding all with galvanized metal gauze coating, in case grain enters passage.The center exhaust tube 1 and the bleeding of ring 2,3 of bleeding are drawn pipe end, at ordinary times with 16 sealings of fluid sealant bowl, when needs are bled, get lower adhesive bowl 16 and change withstand voltage tube connector 7 and be connected with non-return valve 8 on the filter 9.Quantity by center exhaust tube 1, ring 2,3 air extractors of forming of bleeding is installed in granary, what can determine according to the actual grain storage amount of granary, be advisable to place 4 groups of air extractors for the standard granary, for the air extractor that is placed on the granary top, the ring 3 of bleeding of outer ring wherein can be cancelled and not put.Center exhaust tube 1 in the air extractor can adopt the breather pipe (shown in Fig. 3,4) that coats gauze and be radial arrangement in addition, in same granary, also can put into 4 groups of these air extractors, its fairlead of bleeding also is communicated with 16 sealings of fluid sealant bowl or with withstand voltage tube connector 7.

Fitting operation of the present utility model is performed such: when new grain is made to store up storehouse or grain in storage for years and stored up, earlier fairlead 7 ends of respectively bleeding in the air extractor are arranged on wind direction one side when doing to store up, so that extract the trickle foreign material that accumulate in this side grain out.Bleeding in each air extractor drawn pipe end and installed fluid sealant bowl 16, adds water in the filter 9 that division board, moisture separator are housed, and the water yield is dug built in 1/2 place of water level meter 13 marks and is advisable.Good seal ring flange 12 is connected withstand voltage tube connector 7 with the fairlead of bleeding of being bled, check that power supply makes vavuum pump 10 turn to running in accordance with regulations.Vavuum pump 10 by tube connector 11, non-return valve 8 and after filter 9 is communicated with, is assembled on the mobile device, is convenient between each granary, move.Start vavuum pump 10, whenever took out 5～6 minutes, till changing the fairlead of bleeding and exhausting.The number of times and bleeding blanking time of bleeding of each granary is determined according to storing up in the storehouse variations in temperature and extraneous weather condition.Generally behind rainy day or rain, during the air too wet, do not bleed as far as possible.As variations in temperature must be bled in storing up, can suitably start shooting bleeds adjust to store up in temperature, but air is when dry, should in time bleed and discharge wet gas in storing up, to reduce the moisture of grain.Work finishes, and opens the discharging valve 4 of filter 9, and water is drained keeping.
