Description

Technical Field

[0001] This utility model belongs to the technical field of dust collection devices, specifically a dust collection device for Raymond mills. Background Technology

[0002] Raymond mill, also known as a suspension roller mill or pendulum mill, is a high-fineness powder processing equipment widely used in mining, chemical, construction and other industries. The Raymond mill mainly consists of a main unit, analyzer, fan, finished product cyclone separator, micro-powder cyclone separator, and air ducts. The main unit includes key components such as the frame, inlet volute, shovel, grinding rollers, grinding ring, and casing. The working principle of the Raymond mill is as follows: the material to be pulverized is added into the mill through the feed hopper on the side of the casing. The grinding rollers, suspended on the main unit's frame, revolve around the vertical axis while simultaneously rotating on their own axis. Due to centrifugal force during rotation, the grinding rollers swing outwards and press tightly against the grinding ring. At this time, the shovel scoops up the material and delivers it between the grinding rollers and the grinding ring, where the rolling and crushing action of the grinding rollers achieves the purpose of pulverizing the material. However, existing Raymond mills generate dust during the discharge process, affecting the working environment and the health of operators, resulting in poor performance. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a dust collection device for Raymond mills, which effectively solves the problem that dust will be scattered during the discharge process of existing Raymond mills, thereby affecting the working environment and the health of operators.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A dust collection device for a Raymond mill, comprising a pad, a Raymond mill body fixedly installed at one end of the top of the pad, a storage hopper fixedly installed at the other end of the top of the pad, and an equipment base fixedly installed at the other end of the top of the pad and below the storage hopper. A material pipe is fixedly installed between the top of the Raymond mill body and the top of the storage hopper, a discharge valve is fixedly installed at the bottom of the storage hopper, a placement plate is provided above the equipment base, and both sides of the top of the placement plate are fixedly connected to the bottom of the storage hopper by tie rods. A dust collection box is fixedly installed on one side of the storage hopper, and a conveying pipe is fixedly installed at one end of the dust collection box. One end of the conveying pipe extends into the interior of the equipment base and is fixedly installed with a rotating joint. The rotating joint is fixedly installed in the middle of the top of the equipment base. A rotating pipe is rotatably installed on the top of the rotating joint. Three support pipes are fixedly installed at equal intervals in a ring on the upper end surface of the rotating pipe. A dust collection hopper is fixedly installed on the top of each of the three support pipes. A filter hopper is fixedly installed at one end of the dust collection box by bolts. An impeller is provided at the other end of the dust collection box. A drive motor is fixedly installed at the bottom of the dust collection box. A transmission component is provided at the output end of the drive motor. The transmission component is connected to the rotating pipe and the impeller. When the drive motor is running, it outputs power to the rotating pipe and the impeller through the transmission component.

[0005] Preferably, the transmission assembly includes a drive gear, a support frame is rotatably mounted on the bottom of the drive gear, the top of the support frame is fixedly connected to the bottom of the dust collection box, a driven gear is meshed on one side of the drive gear, and a shaft is fixedly mounted in the middle of the driven gear.

[0006] Preferably, the top of the shaft extends into the interior of the dust collection box and is fixedly installed with a driving bevel gear. The upper end of the shaft surface is rotatably connected to the lower part of the dust collection box through an upper bushing. A driven bevel gear is meshed with one side of the driving bevel gear surface. One side of the driven bevel gear is rotatably connected to the inner wall of one end of the dust collection box. The other side of the driven bevel gear is fixedly connected to the impeller.

[0007] Preferably, a lower bushing is rotatably mounted on the lower end of the shaft surface, and the surface of the lower bushing is fixedly connected to the storage hopper via a connecting rod. A drive sprocket is fixedly mounted on the bottom of the shaft, and a positioning strip is rotatably mounted on the bottom of the drive sprocket.

A driven sprocket is fixedly mounted on the surface of the rotating tube, and a chain meshes between the driven sprocket and the drive sprocket.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator grinds the material through the Raymond mill body. The ground powder enters the storage hopper through the material pipe for storage. The operator places the receiving cylinder inside the placement tray and then opens the discharge valve to discharge the material. At the same time as the material is discharged, the operator starts the drive motor to drive the drive gear to rotate along the support frame. When the drive gear rotates, it drives the shaft to rotate inside the upper and lower bushings through the driven gear. When the shaft rotates, it drives the drive sprocket to rotate along the positioning strip. When the drive sprocket rotates, it drives the driven sprocket to rotate through the chain. When the driven sprocket rotates, it drives the rotating tube to rotate along the rotating joint. When the rotating tube rotates, it drives the three dust collection buckets to rotate through the three support tubes.

[0009] While the shaft rotates, it also drives the driven bevel gear to rotate via the active bevel gear. The rotation of the driven bevel gear drives the impeller to rotate and draw in air. Thus, the dust flying during material feeding is evenly and comprehensively sucked into the rotating tube through three rotating dust collection hoppers. The dust entering the rotating tube will pass through the rotating joint and conveying pipe into the filter hopper inside the dust collection box for storage, thereby preventing dust from scattering during material feeding and ensuring a safe working environment. A movable door is hinged on one side of the dust collection box, which operators can open to remove the filter hopper for cleaning. This dust collection device can prevent dust from scattering during the discharge process of the Raymond mill, thereby ensuring a safe working environment and protecting the health of the operators.

[0020] During use, the operator grinds the material through the Raymond mill body 2. The ground powder enters the storage hopper 3 through the material pipe 5 for storage.
