Abstract

The utility model discloses a parallel ventilated grain bin. An opening at the upper end of a bin body (1) is sealed by a bin cover (2); air pipes are arranged on the inner walls of two sides of the bin body (1) perpendicularly to a bin bottom; an air inlet pipe (3) is arranged on one side of the bin body (1); an air outlet pipe (4) is arranged on the other side of the bin body (1); through holes are distributed on the walls of the air inlet pipe (3) and the air outlet pipe (4); the upper ends of the air inlet pipe (3) and the air outlet pipe (4) are sealed; the lower ends of the air inlet pipe (3) and the air outlet pipe (4) are communicated respectively through an air inlet main pipe (5) and an air outlet main pipe (6); an air inlet (5a) extending out of the bin body (1) is connected to the lateral wall of the air inlet main pipe (5); and a fan joint (6a) extending out of the bin body (1) is connected to the lateral wall of the air outlet main pipe (6). The parallel ventilated grain bin has the advantages of simple structure, reasonable design, horizontal air flow and better effect as parallel ventilation is adopted. Simultaneously, as negative-pressure ventilation is adopted, air use quantity is small, pathways of air inside grain piles are long, air force is large, and different air media can be used for finishing different ventilation operations.

Description

The silo of parallel ventilation

Technical field

The utility model belongs to a kind of silo.Specifically a kind of silo that can carry out parallel ventilation.

Background technology

At present, the grain storage of domestic most chamber storehouse all adopts plastic foil airtight, and structure is: in the bottom perforate of stacking the grain heap, serve as to be 0.5 meter full open aperture air chimney apart from semicircle diameter is set with 6 meters, be called for short cage on the ground.During ventilation, open on film with 6 meters be 30 of being opened of distance greater than 1 hole, or progressively open film and could ventilate.The silo defective of this structure is: perforate does not have certain foundation, and this ventilation method air dielectric moves both vertically in the grain heap, and the dead angle is a lot, the effect extreme difference.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of silo that carries out parallel ventilation.

The technical solution of the utility model is as follows: a kind of silo of parallel ventilation, warehouse is a rectangle, the warehouse upper end is uncovered to be sealed by Cang Gai, its key is: perpendicular to standing at the bottom of the storehouse airduct is arranged on the inwall of described warehouse both sides, wherein a side is a blast pipe, opposite side is a discharge pipe, be distributed with gravity vent on described blast pipe and the discharge pipe tube wall, described blast pipe and the sealing of discharge pipe upper end, each free air intake of lower end is responsible for and connection is responsible in air-out, described air intake is responsible for sidewall and is connected with the air intake that stretches out outside the warehouse, and described air-out is responsible for sidewall and is connected with the fan interface that stretches out outside the warehouse.And the connection blower fan, open blower fan warehouse is ventilated, because warehouse air pressure is lower than extraneous, extraneous air just enters from blast pipe, air is advanced then by blast pipe discharges from discharge pipe, forms parallel ventilation.

The blast pipe and the discharge pipe of above-mentioned warehouse both sides are symmetrical arranged.Be symmetrical arranged the parallel ventilation of easier formation.

Above-mentioned blast pipe is identical with the discharge pipe structure, according to former be 8288m with air quantity ³/ h blower fan, 7 of described blast pipes are one group, and each group is responsible for by same air intake and is communicated with, and each root air intake is responsible for an air intake is set.7 one group connects a blower fan, the best results that makes ventilation.

Distance between above-mentioned adjacent blast pipe and the adjacent discharge pipe is 3m.Rule of thumb grain heap radius is about 1.5 settings, and ventilation effect is better.

The area of above-mentioned blast pipe and gravity vent that discharge pipe is opened is 25～35% of a whole airduct sidewall area, and require its performance wind speed be 0.1～0.15m/s.

Beneficial effect: the utility model is simple in structure than vertical ventilation, uses one of blower fan less, uses pipeline less.Reasonable in design, the air bottom horizontal flow sheet, better for parallel ventilation effect, little with air quantity, air is piled path length midway at grain, and wind is big, and available different air dielectric is finished different ventilatings.As do the circulatory fumigation dispenser, only air intake need be connected with the air outlet of blower fan.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, 2, the silo of a kind of parallel ventilation of the utility model, warehouse 1 is a rectangle, warehouse 1 upper end is uncovered by 2 sealings of storehouse lid, warehouse 1 adopts body of wall to surround, and perpendicular to symmetry at the bottom of the storehouse is upright airduct is arranged on the described warehouse 1 both sides inwall, and wherein a side is a blast pipe 3, opposite side is a discharge pipe 4, and the distance between described adjacent blast pipe 3 and the adjacent discharge pipe 4 is 3m.Be distributed with gravity vent on described blast pipe 3 and discharge pipe 4 tube walls, the area of described blast pipe 3 and discharge pipe 4 gravity vent of opening is 25～35% of a whole airduct sidewall area.Described blast pipe 3 and the sealing of discharge pipe 4 upper ends, each free air intake person in charge 5 of lower end and air-out are responsible for 6 and are communicated with, described blast pipe 3 is one group with 7, and each group is responsible for 5 by same air intake and is communicated with, and each root air intake is responsible for 5 an air intake 5a who stretches out outside the warehouse 1 is set.Described discharge pipe 4 is one group with 7 also, and each group is responsible for 6 by same air-out and is communicated with, and each root air-out is responsible for 6 a fan interface 6a who stretches out outside the warehouse 1 is set.When storing grain, grain pushes away at storehouse inner height and blast pipe 3 and discharge pipe 4 highly suitable, covers sealing with film then on grain.
