Technical Field
[0001] The utility model relates to the technical field of silo material feeding, in particular to a silo with a material smooth decompression chamber. Background Art
[0002] In the process of using a silo to transport powdered materials, since the silo is usually a structure with a large upper end and a small lower end, blockages often occur during the process of transporting materials from top to bottom due to problems such as the humidity, viscosity and particle size of the materials. Since the blockage is inside the silo, there are many inconveniences in clearing it; the commonly used clearing methods in the prior art include clearing the blocked part of the silo by vibration and knocking to clear the material, or breaking and clearing the blocked part by opening holes at the blocked position of the silo, and clearing the blockage by adding air cannons and other operating methods. The above methods are not only cumbersome and inefficient, but also only treat the symptoms and not the root cause. They can only be operated passively after the silo is blocked, and cannot actively assist in clearing the blockage during the material discharge process; therefore, there is an urgent need for a silo with a material smooth decompression chamber that can assist in clearing the silo during the material discharge process to ensure smooth material discharge from the silo.

[0019] The following is a clear and complete description of the present invention in conjunction with the accompanying drawings and embodiments:
[0020] like Figures 1 to 3As shown, a silo with a material smooth decompression chamber described in the utility model includes a silo body 1, a decompression chamber connected to the interior of the silo body 1 is provided on the silo body 1, and the decompression chamber is arranged in the easily blocked area in the lower middle part of the silo body 1; the decompression chamber includes a guide cover 2 coaxially arranged on the outside of the silo body 1, the guide cover 2 is made of a metal steel plate that can withstand a certain pressure, the inside of the guide cover 2 is hollow to form a cavity for transitional storage of unblocked airflow, a plurality of guide pipes 3 connected to the interior of the guide pipe 2 are provided on the inner wall of the guide cover 2, the guide pipes 3 pass through the silo body 1 and are connected to the inside of the silo body 1; a gas pipeline 7 connected to the gas source is provided on the outside of the guide cover 2, the gas pipeline 7 is usually connected to a pulse valve, the pulse valve is connected to a buffer tank, and the buffer tank is connected to the gas source so as to transport gases of different pressures into the silo body 1 according to demand.
[0021] During operation, the continuous or regular delivery of controlled gas into the silo body 1 can assist the falling of materials, ensure the smoothness of material discharge from the silo body 1, and effectively prevent the adhesion of materials to the inner wall of the silo body 1, so as to avoid the accumulation of materials on the inner wall of the silo body 1 and cause blockage.
[0022] Furthermore, the opening at one end of the flow guide pipe 3 located inside the silo body 1 is tilted downward so that the output gas flows along the material conveying direction, realizing the auxiliary pushing of the material by the high-pressure gas, and ensuring fast and smooth material discharge. In addition, the flow guide pipes 3 are arranged in multiple rows along the circumferential direction of the inner wall of the flow guide cover 2, and the flow guide pipes 3 of two adjacent rows are arranged alternately up and down to ensure the area covered by the airflow, thereby realizing all-round pushing of the material.
[0023] In addition, a baffle 4 is provided at the front end of each column of partial flow guide tubes 3, and the baffle 4 and the front end of the flow guide tube 3 are spaced apart by a connecting rod 5. In this way, during the high-pressure gas transmission process, the high-pressure gas can be output from the gap between the baffle 4 and the flow guide tube 3 through the interception of the baffle 4. At this time, the high-pressure gas can move along the inner wall of the silo body 1, thereby achieving the purpose of removing the material adhered to the inner wall of the silo body 1, effectively reducing the probability of material accumulation and adhesion on the inner wall of the silo body 1, and providing a guarantee for the smooth falling of the material. Among them, the baffles 4 arranged on the flow guide tubes 3 of two adjacent columns are arranged alternately up and down to achieve the cleaning operation at different heights inside the silo body 1.
[0024] Preferably, in this embodiment, the connecting rod 5 is movably connected to the guide tube 3, so that after the high-pressure gas is cut off, the push baffle 4 can be fitted with the end of the guide tube 3 due to the pressure difference between the inside and outside of the silo body 1, thereby reducing the probability of material blocking the gap between the baffle 4 and the guide tube 3 during the unloading process. This situation is generally suitable for regular delivery of high-pressure gas; specifically, a slide groove can be opened on the side wall of the guide tube 3, and the connecting rod 5 is slidably set in the slide groove.
[0025] In addition, a conical guide platform 6 is provided at one end of the baffle plate 4 close to the inside of the guide tube 3, and the tip of the guide platform 6 is arranged toward the inside of the guide tube 3. The setting of the guide platform 6 can provide guidance for the output high-pressure gas, and smoothly and orderly guide the gas along the arc-shaped slope of the guide platform 6, avoiding the impact of direct action on the baffle plate 4 on the baffle plate 4.
[0026] Furthermore, the guide cover 2 in this embodiment is a detachable two-part structure; and the two split guide covers 2 are non-conductively arranged; each split guide cover 2 is provided with a gas pipeline 7. Two split guide covers 2 are independently connected to a gas pipeline 7 to ensure the balance of the gas input into the silo body 1; wherein the gas pipeline 7 is preferably arranged in the middle of each guide cover 2; each split guide cover 2 is provided with an annular guide cavity 8 at the top, and a plurality of diverter cavities 9 are provided at the lower part of the guide cavity 8, and the number of diverter cavities 9 is the same as that of the guide tubes 3, and the guide tubes 3 of the corresponding columns are connected with the corresponding diverter cavities 9, and the gas input into the guide cover 2 first enters the guide cavity 8, and is distributed to each diverter cavity 9 by the guide cavity 8, and is discharged by the guide tube 3 connected with the diverter cavity 9.
[0027] Furthermore, in this embodiment, the exterior of the silo body 1 is preferably configured as a hyperbolic structure to further ensure smooth material transportation; in addition, a plurality of vibrating machines 10 are spaced apart outside the silo body 1 to assist in solving the problems of silo blockage and bulking, ensuring the smooth falling of materials, and being easy to operate and highly practical.
