Description

Technical Field

[0001] This utility model relates to the field of pulverized coal silos, specifically a high-efficiency pulverized coal silo feeding device. Background Technology

[0002] A pulverized coal silo is a type of fuel transfer station. For boilers with storage-type fuel supply, which have both coal silos and pulverized coal silos, the control of pulverized coal particles is particularly important.

[0003] Existing patent CN213802024U discloses a pulverized coal silo feeding device. The output of a first motor drives a connecting rod to rotate via a first gearbox. The rotating connecting rod drives an arc-shaped blade to rotate, which stirs the pulverized coal within the storage silo. This design prevents large-scale lumps of pulverized coal from clogging the storage silo, thus avoiding equipment malfunctions and reduced efficiency. When the feeding port is blocked, a second hydraulic rod is activated. The telescopic end of the second hydraulic rod, through rollers and a first connecting column, displaces a first L-shaped plate. The first L-shaped plate is positioned appropriately, aligning the conical impeller with the feeding port. Corresponding to the opening, the baffle of the discharge port is opened, and then the second motor is turned on. The output end of the second motor rotates through the connecting shaft of the second gearbox, which drives the conical impeller to rotate. Then the first hydraulic rod is activated, and the telescopic end of the first hydraulic rod rises. Through the short L-shaped plate, the first L-shaped plate and the conical impeller rise. The conical impeller rotates and enters the discharge port, breaking up the clumps of coal powder. The broken coal powder falls onto the guide plate, preventing the coal powder from accumulating at the upper end of the first L-shaped plate. This setting has a good unblocking effect. The breaking device is in direct contact with the clumps of coal powder, making the breaking up more thorough, faster, and more convenient.

[0004] The existing equipment disperses the coal powder, but because coal lumps remain in the coal powder, the existing equipment cannot crush the coal lumps, causing the coal lumps to get stuck at the discharge port and reducing the feeding speed. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency coal powder silo feeding device to solve the problem that existing devices cannot crush coal blocks, causing coal blocks to get stuck at the discharge port and reduce the feeding speed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency coal powder silo feeding device, comprising a silo body, an electric motor installed on the top of the silo body, a fixed cylinder fixed to the output end of the electric motor, the electric motor rotating to drive the fixed cylinder to rotate, and the fixed cylinder penetrating into the interior of the silo body, a screen fixed to the inner wall of the silo body, the screen fixed to the inner wall of the silo body, the screen located at the bottom of the fixed cylinder, a fixed block fixed to the top of the screen, the screen fixed to the fixed block, the fixed block penetrating into the interior of the fixed cylinder, a first conical tooth fixed to the top of the fixed block, the fixed block fixing the first conical tooth, two sets of second conical teeth meshingly connected to the two sides of the outer surface of the first conical tooth, the second conical tooth rotating through the meshing connection of the first conical tooth, and grooves provided on both sides of the fixed cylinder.

[0007] As a further improvement of this utility model: a fixing post is fixed on one side of each of the two sets of second conical teeth. When the second conical teeth rotate, they drive the fixing post to rotate, and the fixing post penetrates the interior of the groove.

[0008] As a further embodiment of this utility model: a fixed shaft is fixed to the outer surface of the fixed column. The fixed shaft prevents the fixed column from affecting the fixed cylinder when it rotates. The fixed shaft is located on the inner wall of the groove. A rolling cylinder is fixed to one side of the fixed column. When the fixed column rotates, it drives the rolling cylinder to make a circular motion while rotating on its own axis.

[0009] As a further embodiment of this utility model: a feed inlet is fixed on one side of the top of the silo body, and the silo body fixes the feed inlet; a discharge outlet is fixed on the bottom of the silo body, and the silo body fixes the discharge outlet.

[0010] As a further embodiment of this utility model: the output end of the motor is fixed with a first fixing rod, and when the motor rotates, it drives the first fixing rod to rotate, and the first fixing rod passes through the top of the first conical tooth.

[0011] As a further embodiment of this utility model: a second fixing rod is fixed to the bottom of the first fixing rod, and the first fixing rod rotates to drive the second fixing rod to rotate, and the second fixing rod passes through the bottom of the fixing block.

[0012] As a further embodiment of this utility model: a fixing plate is fixed to the bottom of the second fixing rod. When the second fixing rod rotates, it drives the fixing plate to rotate.

When the first conical tooth rotates, it drives the fixed column to rotate. When the fixed column rotates, it drives the crushing cylinder to rotate. When the crushing cylinder rotates, it crushes the coal blocks and prevents them from getting stuck at the discharge port.

[0015] 2. By setting up an electric motor, the rotation of the electric motor drives the first fixed rod to rotate, the rotation of the first fixed rod drives the second fixed rod to rotate, the rotation of the second fixed rod drives the fixed plate to rotate, and the rotation of the fixed plate drives the stirring rod to rotate.
