Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a material arch-breaking silo. Background Technology

[0002] When materials are released from the bottom of the silo, some powder raw materials with poor flowability, high viscosity, or high water content often clump, bridge, or block the material due to the pressure of the material above. This affects the normal discharge of materials from the silo. Utility Model Content

[0003] The purpose of this utility model is to provide a material arch-breaking hopper to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a material arch-breaking silo, characterized in that it includes: a silo body, with a feed inlet and an exhaust outlet at the top; a grid, including longitudinal pipes and transverse pipes that are on the same plane and intersecting each other, wherein multiple longitudinal pipes and multiple transverse pipes are arranged parallel to each other, the multiple longitudinal pipes and multiple transverse pipes are interconnected and their ends are all located on the side wall of the silo body, and multiple air outlets are opened at the top of the longitudinal pipes and transverse pipes, and at least one of the longitudinal pipes or transverse pipes is connected to an air inlet pipe for connecting to a gas power source.

[0005] The technical solution has at least the following beneficial effects: When the material enters the silo through the feed inlet, the gas power source introduces gas into the air inlet pipe as the material passes through the grid, causing the gas to be ejected from the air outlet. Under the action of the airflow, longitudinal pipe and transverse pipe, the material is dispersed, so that the material falls evenly and reduces the phenomenon of material clumping, bridging or blockage.

[0006] As a further improvement to the above technical solution, a vibrator is also included to drive the grid to vibrate relative to the silo body. The vibrator can improve the grid's dispersing effect on materials, thereby further reducing the phenomena of material agglomeration, bridging, or blockage.

[0007] As a further improvement to the above technical solution, it also includes a first dispersant and a first motor for driving the first dispersant to rotate. The first dispersant is rotatably mounted on the silo body below the grid. The first motor drives the first dispersant to disperse the material, increasing the looseness of the material and facilitating feeding.

[0008] As a further improvement to the above technical solution, it also includes a second disperser parallel to the first disperser and a drive unit for driving the second disperser to rotate. The second disperser is rotatably mounted on the silo body and located below the first disperser. The drive unit drives the second disperser to further disperse the material, further improving the looseness of the material to facilitate feeding.

[0009] As a further improvement to the above technical solution, the driving component includes a first gear mounted on the first disperser and a second gear mounted on the second disperser, the first gear and the second gear being meshed together. Through the transmission action of the first gear and the second gear, the first motor can simultaneously drive the first disperser and the second disperser to rotate, thereby reducing the number of driving components.

[0010] As a further improvement to the above technical solution, the width of the silo body perpendicular to the axis of the first disperser gradually decreases from top to bottom, and the dispersing range of the second disperser is smaller than that of the first disperser. This facilitates the collection and discharge of materials.

[0011] As a further improvement to the above technical solution, vibrators are installed on both opposite side walls of the silo, and the two vibrators on the two opposite side walls are staggered in the vertical direction. The two vibrators can vibrate the side walls of the silo at different positions to promote material discharge.

[0012] As a further improvement to the above technical solution, transparent viewing windows are installed on both opposite side walls of the chamber, arranged laterally and alternately with the vibrator. These transparent viewing windows allow for easy observation of the interior of the chamber.

[0013] As a further improvement to the above technical solution, a conveying screw is connected to the bottom of the silo body. One end of the conveying screw extends outward from the silo body, and a discharge port and a sampling port are provided on the extended portion. The conveying screw can evenly transport materials to the discharge port and facilitate sampling at the sampling port.

[0014] As a further improvement to the above technical solution, the cross-section of the horizontal tube is circular or polygonal, and the cross-section of the vertical tube is circular or polygonal. Attached Figure Description

[0024] Reference Figure 1-3A material arch-breaking silo includes a silo body 100 and a grid 200. The front and rear width of the silo body 100 gradually decreases uniformly from top to bottom, causing the front and rear opposite sidewalls of the silo body 100 to slope in opposite directions, with the slope angle selectable between 5 degrees and 20 degrees. The left and right sides of the silo body 100 are parallel vertical sidewalls. A feed inlet 110, communicating with the interior, is opened at the center of the top surface of the silo body 100 for allowing material to enter the silo body 100. Exhaust outlets 120, communicating with the interior, are opened on both the left and right sides of the top surface of the silo body 100.

[0025] The grid 200 includes multiple longitudinal pipes 210 and multiple transverse pipes 220. The longitudinal pipes 210 are parallel to each other and arranged horizontally side by side, as are the transverse pipes 220. Both the longitudinal pipes 210 and the transverse pipes 220 are hollow tubes, and they are arranged perpendicularly to each other on the same horizontal plane, allowing them to communicate with each other. Multiple air vents 230 are arranged side by side along the length of each of the longitudinal pipes 210 and transverse pipes 220. These air vents communicate with the internal cavities of the longitudinal pipes 210 and transverse pipes 220, and the air vents 230 face upwards. The ends of the longitudinal pipes 210 and transverse pipes 220 are installed on the side walls of the silo body 100, so that when material enters the silo body 100 from the feed inlet 110, it passes through the grid 200.

[0026] In this embodiment, the cross-sections of the longitudinal tube 210 and the transverse tube 220 are both circular. In other embodiments, the cross-sections of the longitudinal tube 210 and / or the transverse tube 220 may also be polygons such as triangles, quadrilaterals, pentagons, and hexagons. When the cross-section of the longitudinal tube 210 or the transverse tube 220 is a polygon, one edge of the polygon is arranged facing upwards.

[0027] An air inlet pipe 240 is connected to one end of either the longitudinal pipe 210 or the transverse pipe 220. The air inlet pipe 240 is a flexible pipe and communicates internally with both the longitudinal pipe 210 and the transverse pipe 220. The air inlet pipe 240 extends outside the silo body 100 and is connected to a gas power source. The gas power source provides compressed gas, causing the air inlet pipe 240 to form an airflow, which is then ejected from the air outlet 230. After the material enters the silo body 100 through the feed inlet 110, the gas ejected from the air outlet 230 disperses the material as it passes through the grid 200. Simultaneously, the longitudinal pipe 210 and the transverse pipe 220 also disperse the material, ensuring even falling and reducing the occurrence of agglomeration, bridging, or blockage. Furthermore, the air inlet pipe 240 is equipped with an adjustable valve to regulate the air output from the air outlet 230.

[0028] Furthermore, the material arch-breaking silo also includes a vibrator 300. The vibrator 300 can be installed independently on a frame fixed relative to the silo body 100, or it can be installed on the outer wall of the silo body 100. The vibration output end of the vibrator 300 is connected to the longitudinal tube 210 or the transverse tube 220 in the grid 200, so that the vibrator 300 drives the grid 200 as a whole to vibrate relative to the silo body 100. It can be understood that the ends of the longitudinal tube 210 and the transverse tube 220 can be installed on the side wall of the silo body 100 by means of vibration damping rubber rings, or limiting grooves can be opened on the inner side wall of the silo body 100 to allow the ends of the longitudinal tube 210 and the transverse tube 220 to move and be placed, thereby allowing the ends of the longitudinal tube 210 and the transverse tube 220 to vibrate relative to the silo body 100.

[0029] Furthermore, the material breaking hopper also includes a first motor 410, a first dispersant 420, a drive unit, and a second dispersant 430. Both the first dispersant 420 and the second dispersant 430 are located inside the hopper body 100, with the first dispersant 420 positioned below the grid 200 and the second dispersant 430 positioned below the first dispersant 420.

[0030] The first dispersant 420 includes a first rotating shaft rotatably mounted on the silo body 100. The first rotating shaft is horizontally arranged in the left-right direction. Multiple first rods are arranged side-by-side around the outer periphery of the first rotating shaft. The length direction of each first rod is perpendicular to the axis of the first rotating shaft. A head rod parallel to the first rotating shaft is provided at the end of each first rod furthest from the first rotating shaft, making the overall structure T-shaped. The first motor 410 can be fixedly mounted relative to the silo body 100 using a frame, or it can be mounted on the outer wall of the silo body 100. The output end of the first motor 410 is fixedly connected to one end of the first rotating shaft via a coupling, allowing the first motor 410 to drive the first rotating shaft and the multiple first rods to rotate. This causes the material to be dispersed by the rotating first rotating shaft and the first rods when it passes through the first dispersant 420.

[0031] The second dispersant 430 includes a second rotating shaft rotatably mounted on the hopper 100. The second rotating shaft is horizontally arranged in the left-right direction, that is, parallel to the first rotating shaft. Multiple second rods are arranged side-by-side on the outer periphery of the second rotating shaft, with the length direction of the second rods perpendicular to the axis of the second rotating shaft. The driving component includes a first gear 440 and a second gear 450. The first gear 440 is coaxially mounted on one end of the first rotating shaft, and the second gear 450 is coaxially mounted on one end of the second rotating shaft. The first gear 440 and the second gear 450 are meshed together, so that while the first motor 410 drives the first rotating shaft to rotate, it also simultaneously drives the second rotating shaft and the multiple second rods to rotate via the first gear 440 and the second gear 450. This causes the material to be dispersed by the rotating first rotating shaft and the first rods when it passes through the first dispersant 420.

[0032] Understandably, since the second dispersant 430 is located below the first dispersant 420, and the front-to-back width of the silo 100 gradually decreases uniformly from top to bottom, the dispersing range of the second dispersant 430 is smaller than that of the first dispersant 420, thus preventing interference with the silo 100. In other embodiments, the driving component can also be a second motor, with its output end connected to the second rotating shaft via a coupling. The second motor can also be mounted separately on a frame fixed relative to the silo 100, or it can be mounted on the outer wall of the silo 100.

[0033] Furthermore, the material breaking hopper also includes at least two vibrators 500 and at least two transparent viewing windows 510. The at least two vibrators 500 are respectively distributed on the front and rear opposite side walls of the hopper body 100. The at least two transparent viewing windows 510 are respectively distributed on the front and rear opposite side walls of the hopper body 100, and are arranged laterally in a staggered manner with the corresponding vibrators 500. Through the transparent viewing windows 510, the internal condition of the hopper body 100 can be easily observed from the front and rear sides, thereby adjusting the air output of the vent 230, the power of the vibrator 300, and the rotational speed of the first motor 410, etc., to better prevent material agglomeration, bridging, or blockage.

[0034] In this embodiment, a total of four vibrators 500 are provided. Two vibrators 500 are distributed on the front side of the silo body 100, and two vibrators are distributed on the rear side of the silo body 100. The vibrators 500 on different sides are staggered in the vertical direction. For example, the front vibrator 500 is located at the lower part of the silo body 100, and the rear vibrator 500 is located at the upper part of the silo body 100. The vibrators 500 on different sides can vibrate the side wall of the silo body 100 at different positions to prevent material agglomeration, bridging, or blockage, and promote material discharge.

[0035] Furthermore, the material breaking hopper also includes a conveying screw 600, which comprises a shell, a screw shaft, and a drive motor. The drive motor can be separately mounted on a frame relative to the hopper body 100, or it can be mounted on the outer wall of the hopper body 100. The top of a portion of the shell is connected to the bottom of the hopper body 100, allowing material passing through the hopper body 100 to fall onto the screw shaft within the shell. The length of the shell and screw shaft extends beyond the hopper body 100, and a discharge port 610 is provided at the bottom of the portion extending beyond the hopper body 100. A sampling port 620 is provided above the corresponding discharge port 610. The drive motor drives the screw shaft to rotate, thereby allowing the material falling onto the screw shaft to be conveyed to the discharge port 610 and output as the screw blades rotate.

[0036] When materials containing moisture enter the upper part of the silo 100 through the feed inlet 110, compressed air is introduced into the grid 200 and the materials are dispersed by the vibration of the vibrator 300, which promotes the uniform entry of materials into the middle and rear processes of the silo 100. At the same time, the opening of the compressed air valve and the vibration intensity of the vibrator 300 can be adjusted to control the flow rate of the materials, prevent the formation of "rat holes" or "rushing" phenomena in the silo 100, and thus achieve more stable and controllable feeding.

[0037] When high-temperature materials enter the silo 100, water droplets may form on the inner wall of the silo 100, resulting in a high moisture content. At this time, under the action of the vibrating grid 200, the rapper 500, and the dispersant, the hot air can be discharged from the exhaust port 120 at the top. This prevents caking, "rat holes," and other blockages.

[0038] In addition, the grid 200 is made according to the size of the hopper 100. The gap between the air outlet 230 and the grid 200 can be adjusted according to the material flow state to keep it as suitable as possible, so as to avoid it being too small or too small to achieve the air blowing effect.

[0039] In practice, the grid 200, air inlet pipe 240, vibrator 300, and rapper 500 can be installed first. Material enters the upper part of the silo 100. Under the action of the grid 200, which has a vibrator 300 and an air outlet 230, the material is evenly fed to the first disperser 420 and the second disperser 430. The rapper 500 prevents material from caking or blocking within the silo 100. After being dispersed by the dispersers, the material is then conveyed to the downstream process via the bottom conveyor screw 600. The transparent window 510 allows for simultaneous observation of the material's condition within the silo 100.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
