Description

Technical Field

[0001] This utility model relates to the technical field of powder tank semi-trailers, specifically to a tank structure for a vertical powder tank semi-trailer. Background Technology

[0002] A powder tanker truck, also known as a powder and granular material transport vehicle, is a specialized vehicle used for transporting powdery and granular materials. It utilizes pneumatic conveying principles to draw materials into or discharge them from the tank, and is widely used in various industries such as chemical, building materials, and food processing. Powder tanker trucks typically have a tank body for holding the goods; the tank body, as the core component of the truck, undertakes the important task of storing and transporting powdery and granular materials.

[0003] The bottom of the tank is generally designed in a conical shape. This design facilitates the smooth discharge of materials during unloading by relying on their own gravity and pneumatic conveying, reducing the amount of material residue at the bottom of the tank.

[0004] However, most powder tank semi-trailers only have one cone, resulting in a slow unloading speed. After unloading, powder particles may adhere to the inner wall, leading to incomplete unloading and potential blockage of the unloading port. Therefore, this does not meet the existing requirements. To address this, we propose a tank structure for a vertical powder tank semi-trailer. Utility Model Content

[0005] The purpose of this utility model is to provide a tank structure for a vertical powder tank semi-trailer, in order to solve the problems mentioned in the background art, such as most powder tank semi-trailers having only one cone, slow unloading speed, and the possibility of powder particles adhering to the inner wall after unloading, resulting in incomplete unloading, and the possibility of blockage at the unloading port.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tank structure for a vertical powder tank semi-trailer, comprising a tank body, wherein a storage cavity is provided inside the tank body, and threaded rods are installed at the top and bottom of the storage cavity. An annular plate is fitted on the outer surface of the two threaded rods, and an annular brush plate is installed on the outer surface of the annular plate. Four discharge ports are evenly provided on the lower end face of the tank body, and a discharge hopper is fixedly installed on the inner side of the discharge ports. A dispersing device is provided on the inner side of the discharge hopper, and the dispersing device includes a rotating shaft. Multiple dispersing rods are evenly installed on the outer surface of the rotating shaft. A drive device for rotating the rotating shaft is installed on one side of the discharge hopper. A sealing cover is fitted on the lower part of the outer surface of the discharge hopper, and a sealing plate is fixedly installed on the upper end face of the inner wall of the sealing cover.

[0007] Preferably, a feed pipe is installed on one side of the upper end face of the tank, and a cover plate is threadedly connected to the upper end face of the feed pipe. A number of bristles are evenly installed on the outer surface of the annular brush plate.

[0008] Preferably, the outer surface of the hopper is provided with an external thread, the inner surface of the sealing cover is provided with an internal thread, and the internal thread and the external thread are screwed together, so that the sealing plate can be inserted into the inner side of the hopper.

[0009] Preferably, a second motor is installed above and below one side of the tank via a motor cavity. The output end of the second motor is fixedly connected to one end of the threaded rod via a short shaft. The other end of the threaded rod is rotatably connected to the inner wall of the storage cavity via a bearing. Threaded holes are provided above and below the outer surface of the annular plate, and the threaded rod is screwed into the threaded holes.

[0010] Preferably, the driving device includes a housing, a first motor is mounted on the top surface of the inner wall of the housing, a vertical shaft is fixedly connected to the output end of the first motor, a driving bevel gear is sleeved on the outer surface of the vertical shaft, a driven bevel gear is provided on one side of the driving bevel gear, and a horizontal shaft is welded to the inner ring of the driven bevel gear.

[0011] Preferably, the driving bevel gear meshes with the driven bevel gear, the other end of the horizontal shaft is fixedly connected to one end of the rotating shaft, the other end of the rotating shaft is rotatably connected to the inner wall of the hopper through a bearing, the upper end face of the shell is fixedly connected to the lower end face of the tank, and the outer surface of the shell is fixedly connected to the outer surface of the hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a threaded rod, an annular plate, an annular brush, and an annular brush plate. After the material is fed, the switch of the second motor can be turned on. The second motor drives the threaded rod to rotate, thereby causing the annular plate to move left and right on the outer surface of the threaded rod, which in turn drives the annular brush plate to move left and right. The brush bristles can clean the inner wall of the storage cavity and brush off the powder adhering to the inner wall of the storage cavity, thereby reducing material residue.

[0014] 2. This utility model, by setting up a driving device and a dispersing device, can control the switch of the first motor. The first motor drives the vertical shaft to rotate, which in turn drives the active bevel gear to rotate. The rotation of the active bevel gear drives the driven bevel gear to rotate, which in turn drives the horizontal shaft to rotate. The rotation of the dispersing rod can stir the powder passing through the hopper, accelerate the discharge, and prevent powder blockage. This utility model can avoid the hopper from getting blocked and can accelerate the discharge speed. Attached Figure Description

[0024] A second motor is installed on the upper and lower sides of one side of the tank 1 through a motor cavity. The output end of the second motor is fixedly connected to one end of the threaded rod 6 through a short shaft. The other end of the threaded rod 6 is rotatably connected to the inner wall of the storage cavity 2 through a bearing.
