Description

Technical Field

[0001] This utility model relates to the field of metal cone-bottom silos, specifically a metal cone-bottom silo. Background Technology

[0002] A metal cone-bottom silo is a cylindrical silo made of metal with a cone-shaped bottom. It is mainly used to store free-flowing granular products, such as corn and wheat. The cone shape at the bottom allows the granular products to flow smoothly, reducing blockages and accumulation.

[0003] Existing metal conical bottom silos, such as the double-layer conical bottom grain silo proposed in patent application number "CN201510547032.8", include an inner second conical bottom plate and an outer first conical bottom plate. A ventilation cavity is formed between the first and second conical bottom plates. The second conical bottom plate has several holes that communicate with the inside of the grain silo. A fan is connected to an annular air duct through an interface. The annular air duct has an air outlet that communicates with the ventilation cavity. The double-layer conical bottom structure is set up, and the second conical bottom plate is covered with through holes to form a full conical ventilation structure.

[0004] However, existing technologies have shortcomings. Grain kernels are usually accompanied by dust or grain husks. These small particles accumulate at the bottom of the cone-bottom silo, blocking the holes in the second cone bottom plate, causing some holes to be unable to ventilate and affecting the ventilation effect of the cone-bottom silo. Therefore, a metal cone-bottom silo is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a metal cone-bottom hopper to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A metal conical bottom chamber includes an outer conical bottom plate and an inner conical bottom plate. The inner conical bottom plate is fixedly connected to the inside of the outer conical bottom plate, and a ventilation cavity is formed between the outer and inner conical bottom plates. Multiple sets of through holes are opened through the inner conical bottom plate. Multiple sets of sealing frames are fixedly connected to the inner wall of the outer conical bottom plate. A sealing slide plate is slidably connected to each of the multiple sealing frames. Multiple sets of sealing posts are fixedly connected to one side of the sealing slide plate, and a spring is fixedly connected to the other side. The multiple sets of sealing posts are respectively inserted into the multiple sets of through holes for sealing the through holes. The end of the spring is fixedly connected to the inner wall of the sealing frame for pushing the sealing slide plate to reset.

[0008] Preferably, the inner and outer conical base plates are coaxial, and a discharge port is fixedly connected between the lower ends of the inner and outer conical base plates. The discharge port is connected to the interior of the inner conical base plate. An annular air duct is fixedly connected to the outer ring of the discharge port. An air inlet is fixedly connected to the lower end of the annular air duct, and an air outlet is fixedly connected to the upper end of the annular air duct. An air inlet is opened at the lower end of the outer conical base plate, and the end of the air outlet away from the annular air duct is fixedly connected to the air inlet.

[0009] Preferably, multiple sets of fixing columns are fixed between the outer conical base plate and the inner conical base plate to maintain the spatial stability between the outer and inner conical base plates. The multiple sets of fixing columns are located on both sides of multiple sets of sealing frames. Multiple sets of reinforcing ribs are fixed between the upper end of the annular air duct and the outer wall of the outer conical base plate. The multiple sets of reinforcing ribs surround the outside of the discharge port.

[0010] Preferably, the outer ring conical base plate has multiple sets of support columns fixed to its outer wall. The multiple sets of support columns are arranged in a circumferential array and surround the outer ring conical base plate. Reinforcing frames are fixed between adjacent support columns, and bases are fixed to the lower ends of the multiple sets of support columns.

[0011] Preferably, a rotating ring is rotatably installed on the inner wall of the annular duct, and multiple sets of fan blades are fixed to the outside of the rotating ring.

[0014] This invention utilizes a sealing frame and other structures installed between the outer and inner conical bottom plates. Multiple sets of sealing posts correspond to multiple sets of through holes. A spring compresses a sealing sliding plate, causing the sealing sliding plate to drive the sealing posts to engage with the through holes, thus sealing the through holes and preventing dust and grain shavings from clogging them. When hot air is introduced into the ventilation chamber, the increased pressure compresses the sealing sliding plate, causing the sealing posts to disengage from the through holes, opening them. Air then enters the inner conical bottom plate through the through holes, ventilating and drying the grain inside the conical bottom silo. This metal conical bottom silo can both ventilate and dry the grain at the bottom of the silo and prevent the through holes from clogging, ensuring the ventilation effect of the conical bottom silo.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A metal cone-bottom hopper, such as Figures 1-6 As shown, it includes an outer conical base plate 1 and an inner conical base plate 2. The inner conical base plate 2 is fixed inside the outer conical base plate, and a ventilation cavity is formed between the outer conical base plate 1 and the inner conical base plate 2. Multiple sets of through holes 3 are opened through the inner conical base plate 2. Multiple sets of sealing frames 9 are fixed to the inner wall of the outer conical base plate 1. Each set of sealing frames 9 is slidably connected to a sealing slide plate 10. Multiple sets of sealing posts 11 are fixed to one side of the sealing slide plate 10, and a spring 12 is fixed to the other side. The multiple sets of sealing posts 11 are respectively inserted into the multiple sets of through holes 3 for sealing the through holes 3. The end of the spring 12 is fixed to the inner wall of the sealing frame 9 for pushing the sealing slide plate 10 to reset.

[0026] By installing a sealing frame 9 between the outer conical bottom plate 1 and the inner conical bottom plate 2, multiple sets of sealing columns 11 correspond to multiple sets of through holes 3. Springs 12 compress the sealing sliding plate, causing the sealing sliding plate to drive the sealing columns 11 to insert into the through holes 3, thus sealing the through holes 3 and preventing dust and grain shavings from clogging them. When hot air is introduced into the ventilation chamber, the pressure increases, which compresses the sealing sliding plate, causing the sealing columns 11 to disengage from the through holes 3. The through holes 3 open, and air enters the inner conical bottom plate 2 through the through holes 3, ventilating and drying the grain in the conical bottom silo. This metal conical bottom silo can both ventilate and dry the grain at the bottom of the conical bottom silo and prevent the through holes 3 from clogging, ensuring the ventilation effect of the conical bottom silo.

[0027] Spring 12 is always in a compressed state, sealing the sealing sliding plate and sealing frame 9. The air pressure in the ventilation cavity compresses and pushes the sealing sliding plate to slide, ventilating into the ventilation cavity. This increases the air pressure and compresses the sealing sliding plate. The sealing column 11 may produce two phenomena: one is that the sealing column 11 is always detached from the through hole 3 during ventilation; the other is that the sealing column 11 reciprocates in and out of the through hole 3 during ventilation, with pressure relief and pressure increase occurring repeatedly in the ventilation cavity. Both of these can block the through hole 3 during non-ventilation and open the through hole 3 during ventilation.

[0028] A limit frame 13 is provided on the sealing frame 9 to limit the position of the sealing slide plate 10 and prevent the sealing post 11 from being overly inserted into the through hole 3.

[0029] Similarly, the cylindrical silo at the top of the cone-bottom silo can be designed as a double-layer structure, which can provide additional ventilation to the top of the cone-bottom silo.

[0030] like Figures 1-4 As shown, the inner conical base plate 2 and the outer conical base plate 1 are coaxial. A discharge port 5 is fixedly connected between the lower ends of the inner conical base plate 2 and the outer conical base plate 1. The discharge port 5 is connected to the interior of the inner conical base plate 2. An annular air duct 6 is fixedly connected to the outer ring of the discharge port 5. An air inlet 7 is fixedly connected to the lower end of the annular air duct 6. An exhaust port 8 is fixedly connected to the upper end of the annular air duct 6. An air inlet 14 is opened at the lower end of the outer conical base plate 1. The end of the exhaust port 8 away from the annular air duct 6 is connected to the air inlet 14.

[0031] The grain is located inside the inner conical bottom plate 2 and can be discharged through the discharge port 5. When storing the grain, the discharge port 5 is blocked, and the air inlet 7 is connected to an external hot air fan. There are multiple sets of air inlets 7, which can be blocked or connected to an external hot air fan as needed to fill the annular air duct 6 with air. The air enters the inner conical bottom plate 2 through the exhaust port 8 and the air inlet 14 to ventilate and dry the grain inside the inner conical bottom plate 2.

[0032] like Figures 1-4As shown, multiple sets of fixing columns 4 are fixed between the outer conical base plate 1 and the inner conical base plate 2 to maintain the spatial stability between the outer conical base plate 1 and the inner conical base plate 2. The multiple sets of fixing columns 4 are located on both sides of the multiple sets of sealing frames 9. Multiple sets of reinforcing ribs 15 are fixed between the upper end of the annular air duct 6 and the outer wall of the outer conical base plate 1. The multiple sets of reinforcing ribs 15 surround the outside of the discharge port 5.

[0033] The fixed column 4 increases the stability between the outer ring conical base plate 1 and the inner ring conical base plate 2, making them connected and fixed. The reinforcing rib 15 increases the structural stability between the outer ring conical base plate 1 and the annular duct 6.

[0034] like Figures 1-3 As shown, multiple sets of support columns 20 are fixed to the outer wall of the outer ring conical base plate 1. The multiple sets of support columns 20 are arranged in a circular array and surround the outside of the outer ring conical base plate 1. A reinforcing frame 22 is fixed between adjacent support columns 20. A base 21 is fixed to the lower end of each set of support columns 20.

[0035] The support column 20 supports the cone-shaped bottom compartment, the reinforcement frame 22 increases the support capacity of the support column 20, and the base 21 increases the contact area between the support column 20 and the ground, thereby increasing the stability of the support column 20.

[0036] like Figures 3-6 As shown, a rotating ring 16 is rotatably installed on the inner wall of the annular duct 6. Multiple sets of fan blades 17 are fixed to the outside of the rotating ring 16. The multiple sets of fan blades 17 are arranged in a circumferential array. The air inlet 7 is located below the fan blades 17, and the air outlet 8 is located above the fan blades 17.

[0037] When ventilation is provided in the air inlet 7, the air enters the annular duct 6 and applies a thrust to the inclined fan blades 17, causing the fan blades 17 to rotate and drive the rotating 16 to rotate. This causes the fan blades 17 to turbulent the airflow in the annular duct 6, preventing the air entering the air inlet 7 from entering the exhaust outlet 8 nearby, and increasing the uniformity of the airflow in the annular duct 6.

[0038] like Figure 4 and Figure 6 As shown, an annular groove 18 is provided between the inner wall of the rotating ring 16 and the inner wall of the annular air duct 6, and multiple sets of ball bearings 19 are rolled and installed in the annular groove 18.

[0039] The ball bearing 19 reduces the friction between the rotating ring 16 and the inner wall of the annular duct 6, making it easier for the rotating ring 16 to rotate.

[0040] The working principle of the metal cone-bottom chamber provided by this utility model is as follows:

[0041] By installing a sealing frame 9 between the outer conical bottom plate 1 and the inner conical bottom plate 2, multiple sets of sealing columns 11 correspond to multiple sets of through holes 3. Springs 12 compress the sealing sliding plate, causing the sealing sliding plate to drive the sealing columns 11 to insert into the through holes 3, thus sealing the through holes 3 and preventing dust and grain shavings from clogging them. When hot air is introduced into the ventilation chamber, the pressure increases, which compresses the sealing sliding plate, causing the sealing columns 11 to disengage from the through holes 3. The through holes 3 open, and air enters the inner conical bottom plate 2 through the through holes 3, ventilating and drying the grain in the conical bottom silo. This metal conical bottom silo can both ventilate and dry the grain at the bottom of the conical bottom silo and prevent the through holes 3 from clogging, ensuring the ventilation effect of the conical bottom silo.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
