Abstract
The utility model relates to a guiding and pressure-reducing device for a grain silo. The utility model is characterized in that the guiding and pressure-reducing device is composed of a central guide tube which is vertically arranged and used for transferring the grain in and out of the grain silo. Holes used for transferring the grain in and out of the grain silo are uniformly arranged on the tube wall of the central guide tube. An upper opening of the central guide tube is fixed on the top of the silo, and a lower opening is arranged at the point of a bell mouth of the silo. The utility model can not only effectively solve the problem of dynamic overpressure but also the phenomenon of automatic grading when grain enters the silo.
Description
The utility model relates to a kind of storage device, relates to a kind of grain storage silo water conservancy diversion pressure purger specifically.
Produce travelling load during the discharging of grain storage silo and cause that the dynamic overpressure problem of silo wall and funnel is the problem that the various countries scholar is paid close attention to always.Grasp substantially although produce the factor of travelling load, provide the computing formula of considering travelling load and solve actual engineering problem is that all right ripe.But the various countries scholars also find and by many evidences, if can change the liquid form of grain when discharging in the silo, just can eliminate the dynamic overpressure problem that produces owing to discharging.Use the earliest abroad that a kind of to be called as relief pipe (being called anti-dynamic load pipe in the translation) device be in the fifties, formally be published in 1956 (can referring to " silo theory and practice " translations), can eliminate the dynamic overpressure problem that produces owing to discharging with this device.
What China used the relief pipe device the earliest is jiangsu wuxi county grains bureau.Its version is round tube, has some holes on the tube wall, and the lower port of pipe is located in bell mouth place of silo, and it highly is about about 4/5 of silo height.The relief pipe device that this grains bureau adopted is same as the external at that time device that adopts, the function of this device only is dynamic overpressure phenomenon when eliminating discharging and design-calculated, storage process aspect for grain does not have the improvement effect, the automatic classification phenomenon when putting in storage as grain.The automatic classification of so-called grain is exactly that grain is risen freely from the storehouse and thrown following time, quality is good under the effect of gravity will flow in the middle part from great particle, impurity will be thrown near the bulkhead and will be deposited in together in grain that deadweight of poor quality is little and the grain, and impurity by chance is exactly to cause the grain mouldy main root that goes bad easily in these ropy grains and the grain.
The purpose of this utility model is exactly at the problems referred to above and deficiency, both can effectively solve the dynamic overpressure problem for the grain storage industry provides a kind of, the grain storage silo water conservancy diversion pressure purger of the automatic classification phenomenon in the time of can solving grain again and put in storage.
The purpose of this utility model can adopt following measure to realize:
Grain storage silo of the present utility model is made up of a centre pipe that is used for grain turnover storehouse of vertically setting up with the water conservancy diversion pressure purger; Be evenly equipped with the hole that is used for the grain turnover on the tube wall of described centre pipe, its Cang Ding that is fixed in suitable for reading, bell mouth place in end opening extend neck storehouse.
In order to strengthen the stability of centre pipe, the reinforced pipe that to be evenly equipped with four cross sectional shapes on the outer tube wall around described centre pipe be semicircular structure, the common formation of described four reinforced pipes and centre pipe one integral structure is evenly equipped with the hole that is used for the grain turnover from top to bottom on the tube wall of the centre pipe between per two adjacent reinforced pipes.
In order to realize the measurement automation of material level, the material level proving installation can be installed in the inner chamber of a reinforced pipe in described four reinforced pipes, and on the wall of this pipe, offer the hole that is used for the grain turnover from top to bottom.
The utility model principle of work and advantage thereof are as follows:
Grain enters centre pipe by the centre pipe mouth of pipe that is positioned at Cang Ding when a, warehouse entry, in the hole that is provided with on being arranged on the centre pipe tube wall flows as the storehouse automatically.Because during the grain warehouse entry is to flow in the storehouse in order by centre pipe, so eliminated the automatic classification phenomenon when grain puts in storage, so still be blended in behind impurity and the ropy grain warehouse entry among the whole grain heap, relatively disperse, also just be difficult for producing the moldy metamorphism phenomenon.
B, when putting out cereal, in the storehouse grain of grain heap surface will flow in an orderly manner automatically centre pipe by the storehouse at the bottom of bell mouth flow to outside the storehouse on the conveyer, grain below the grain heap surface is transfixion then, grain from the top layer flow into from level to level centre pipe unload deliver from godown outside, can not produce because grain heap overall flow and grain heap knot encircle the generation of the dynamic overpressure force phenomenon that causes bulkhead.The avoiding of this phenomenon takes place bring benefit also can for the design of silo, as can not considering the supercharging coefficient of dynamic pressure in the design, reduces the silo cost.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
As shown in Figure 1, grain storage silo of the present utility model is made up of a centre pipe (1) that is used for grain turnover storehouse of vertically setting up with the water conservancy diversion pressure purger; Its (2) suitable for reading are fixed in Cang Ding, bell mouth place in end opening (3) extend neck storehouse; In order to strengthen the stability of centre pipe, the reinforced pipe (5) that to be evenly equipped with four cross sectional shapes on the outer tube wall around described centre pipe (1) be semicircular structure, described four reinforced pipes (5) constitute an integral structure jointly with centre pipe (1), are evenly equipped with the hole (4) that is used for the grain turnover on the tube wall of the centre pipe (1) between the per two adjacent reinforced pipes (5) from top to bottom.
In order to realize the measurement automation of material level, material level proving installation (7) is installed in the inner chamber of a reinforced pipe in described four reinforced pipes (5), and on the wall of this pipe, is offered the hole (6) that is used for the grain turnover from top to bottom.
