Description

Technical Field

[0001] The utility model relates to the technical field of a buffer silo, in particular to a buffer silo mechanism for preventing air leakage. Background Art

[0002] Buffer silo is a device used for temporary storage and regulation of material flow in industrial production. Its main functions include: buffering material supply, maintaining production continuity and stability, regulating material flow and pressure, ensuring the normal operation of subsequent processes, and playing a role in material homogenization, thereby improving the consistency of product quality. Buffer silo is usually set in the middle of the material conveying pipeline to temporarily store materials conveyed from upstream.

[0003] The utility model patent with application number: CN202322775765.X and publication number: CN220844607U (hereinafter referred to as "prior art 1") discloses a buffer silo with screening function, including a silo body, characterized in that: the silo body is equipped with a buffer assembly, the buffer assembly includes a mounting rod slidably plugged in the center of the silo body, one end of the bottom of the mounting rod is fixedly connected with a buffer frame in contact with the inner wall of the silo body, a convex block is arranged on the top of the circumferential outer wall of the silo body, a screw is threadedly connected in the middle of the convex block, the screw and the top of the mounting rod are rotatably connected with the same connecting plate, the screw and the mounting rod share a transmission assembly, the transmission assembly includes two pulleys rotatably connected on both sides of the outer wall of the top of the connecting plate, and the two pulley sleeves are provided with the same skin;

[0004] The specification of prior art 1 discloses a buffer silo with a screening function. When in use, a buffer component is set to ensure that a buffering effect is played during the falling process of the material; however, in actual applications, since the bottom of the silo is a funnel-shaped structure, when the material in the silo is discharged, the discharge speed of the center position is faster than the discharge speed of the surrounding materials, resulting in a depression in the center position of the material accumulated inside the silo after the valve is closed, which makes the height of the center position of the material smaller, so that the center position of the accumulated material is closer to the discharge port, and the gas outside the discharge port is easier to enter the interior of the silo. Summary of the invention

[0005] The utility model provides a buffer bin mechanism for preventing air leakage, aiming to solve the problem that in the prior art, the buffer bin may leak air due to depressions formed after material accumulation.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A buffer silo mechanism for preventing air leakage comprises a silo shell, a motor, a rotating shaft and an air leakage prevention device, wherein the silo shell is provided with a feed inlet and a discharge port, the discharge port is provided with a discharge valve, and the feed inlet is provided with a feed valve; the motor is installed above the silo shell; one end of the rotating shaft is fixedly connected to the output shaft of the motor, and the other end is rotatably connected to the bottom of the silo shell; the air leakage prevention device is arranged inside the silo shell, and is used to prevent air leakage inside the silo shell;

[0008] Among them, the anti-leakage device includes a spiral blade, a sensor and a material stripping plate. The spiral blade is arranged at the tail end of the rotating shaft, and the lower end of the spiral blade is located in the discharge port. There are two sensors, namely a first sensor and a second sensor. The first sensor is located at the D1 position of the silo shell, and the second sensor is located at the D2 position of the silo shell. The first and second sensors are connected to the feed valve and the discharge valve through the controller, and are used to sense the height of the material inside the silo shell.

[0009] Furthermore, a feed bin is provided on the feed port.

[0010] Furthermore, the feed bin includes a conical feed barrel and a feed pipe, the conical feed barrel is connected to the feed port, and the feed pipe is arranged above the conical feed barrel.

[0011] Furthermore, a support frame is provided outside the silo shell, and the support frame is used to support the silo shell.

[0012] Furthermore, a plurality of angle irons are provided on the outer surface of the silo shell, and the silo shell is connected to the support frame through the plurality of angle irons.

[0013] Furthermore, a mounting frame is provided above the silo shell, a fixed end of the motor is provided on the mounting frame, and a movable end passes through the mounting frame and the silo shell and is rotatably connected to the silo shell.

[0014] Furthermore, the motor is connected to the rotating shaft through a coupling.

[0015] Furthermore, the material shifting plate is an L-shaped structure.

[0016] Furthermore, bristles are provided at the end of the stripping plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model mainly includes a silo shell, a motor, a rotating shaft and an anti-leakage device. In actual use, the staff first determines that the discharge valve is closed, and then opens the feed valve to put the material into the silo shell through the feed port. When the position of the material is above the D1 position on the silo shell (the highest position of the stored material), the first sensor senses the height of the material, and then controls the discharge valve to open through the controller. At the same time, the motor is controlled to rotate, and the motor drives the spiral blade and the material-diverting plate to rotate. At this time, the material is discharged from the silo shell under the action of the spiral blade. When the height of the material is at the D2 position (the lowest position of the stored material), at this time, since the material in the silo is being discharged, the discharge speed at the center position is faster than the discharge speed of the surrounding materials, resulting in the material being discharged after the valve is closed. The center of the material accumulated inside the silo will be concave. As the shaft continues to rotate, the material shifting plate shifts the higher materials around to the center, so that the material surface remains horizontal. After the material contacts the second sensor, the second sensor drives the feed valve to open and controls the discharge valve to close. The material enters the silo shell from the feed port until the height of the material reaches the D1 position and the feed valve is closed again. The above operation is repeated. The advantage of this setting is that it can ensure that the material will not overflow during storage. After the material is discharged, the first seal is formed by the spiral blades, and the second seal is formed by stacking the material. The material is shifted by the material shifting plate to ensure that the material surface is horizontal, prevent gas from entering from the middle of the material to cause leakage, and form a third seal, which effectively prevents leakage.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the protection scope of the present invention.

[0024] See also Figure 1 and Figure 2 As shown, this embodiment discloses a buffer silo mechanism for preventing air leakage, including a silo shell 101, a motor 104, a rotating shaft 105 and an air leakage prevention device, wherein the silo shell 101 is provided with a feed port 102 and a discharge port 103, the discharge port 103 is provided with a discharge valve, and the feed port 102 is provided with a feed valve; the motor 104 is installed above the silo shell 101; one end of the rotating shaft 105 is fixedly connected to the output shaft of the motor 104, and the other end is rotatably connected to the bottom of the silo shell 101; the air leakage prevention device is arranged inside the silo shell 101, and the air leakage prevention device is used to prevent air leakage inside the silo shell 101;

[0025] The anti-leakage device includes a spiral blade 106, a sensor and a material stripper plate 107. The spiral blade 106 is arranged at the tail end of the rotating shaft 105, and the lower end of the spiral blade 106 is located in the discharge port 103. There are two sensors, namely a first sensor 108 and a second sensor 109. The first sensor 108 is located at the D1 position of the silo shell 101, and the second sensor 109 is located at the D2 position of the silo shell 101. The first and second sensors are connected to the feed valve and the discharge valve through the controller, and are used to sense the height of the material inside the silo shell 101.

[0026] The utility model mainly includes a silo shell 101, a motor 104, a rotating shaft 105 and an anti-leakage device. In actual use, the staff first determines that the discharge valve is closed, and then opens the feed valve to put the material into the silo shell 101 through the feed port 102. When the position of the material is above the D1 position (the highest position of the stored material) on the silo shell 101, the first sensor 108 senses the height of the material and controls the discharge valve to open through the controller. At the same time, the motor 104 is controlled to rotate, and the motor 104 drives the spiral blade 106 and the material-diverting plate 107 to rotate. At this time, the material is discharged from the silo shell 101 under the action of the spiral blade 106. When the height of the material is at the D2 position (the lowest position of the stored material), at this time, since the material in the silo is discharged, the discharge speed of the center position is faster than that of the four positions. The material discharge speed around is faster, resulting in a depression in the center of the material accumulated inside the silo after the valve is closed. As the rotating shaft 105 continues to rotate, the material shifting plate 107 shifts the higher materials around to the center, so that the material surface remains horizontal. After the material contacts the second sensor 109, the second sensor 109 drives the feed valve to open and controls the discharge valve to close. When the height of the material reaches the D1 position, the feed valve is closed again, and the above operation is repeated. The advantage of this arrangement is that it can ensure that the material will not overflow during storage. After the material is discharged, the spiral blade 106 forms a first seal, and the second seal is formed by stacking the material. The material is shifted by the material shifting plate 107 to ensure that the material surface is horizontal, prevent gas from entering from the middle of the material to cause leakage, and form a third seal, which effectively prevents leakage.
