Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, and more specifically to a rotor type coal powder metering device. Background Art

[0002] The existing rotor-type coal powder meter needs to process the coal powder through blowing and rotating wheels, and then send it into a specific space for metering to ensure that the amount of coal powder is relatively accurate. However, the feed ports of the existing rotor-type coal powder meter are mostly simple in structure and small in number, making it difficult to ensure that the coal powder entering the device is evenly dispersed at one feed port, and even agglomeration may occur due to excessive humidity. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a rotor-type coal powder metering device to solve the problem that the feed inlets of the existing rotor-type coal powder meters in the above-mentioned background technology are mostly simple in structure and small in number, making it difficult to ensure that the coal powder entering the device is evenly dispersed at one feed inlet, and even causing agglomeration due to excessive humidity.

[0004] The utility model provides the following technical scheme: it comprises an equipment bottom plate, a rotor barrel body is fixedly installed on the top of the equipment bottom plate, a motor is arranged on the top of the rotor barrel body, the bottom end of the motor extends to the interior of the rotor barrel body, a pulverized coal rotor mixer is fixedly installed on the bottom end of the motor, a discharge port is provided on one side of the rotor barrel body, two feed ports are provided on one side of the top end of the rotor barrel body, filter screens are installed on the feed ports through magnet adsorption, and the aperture sizes of the two filter screens are different, a metering weighing box is fixedly installed on one side of the equipment bottom plate, one side of the metering weighing box extends to the interior of the discharge port, and a humidity sensor is fixedly installed inside the feed port. When in use, the coal powder pile to be measured is connected to the two feed ports through the air duct and the fan, so that the coal powder can pass through the two feed ports and enter the rotor barrel body more evenly. When the particle size of the coal powder needs to be screened to prevent agglomeration, a filter screen can be installed at the feed port through a magnet to filter the coal powder by particle size. Not only can coal powder of different particle sizes be screened out, but the humidity sensor inside the feed port can monitor the humidity and particle size of the coal powder at the feeding point of each feed port in real time. In actual use, it effectively solves the problem that the feed ports of existing rotor-type coal powder meters are mostly simple in structure and small in number, and it is difficult to ensure that the coal powder entering the device is evenly dispersed at one feed port, and even the problem of excessive humidity and agglomeration may occur.

[0005] Furthermore, a bottom support frame is fixedly installed at the bottom end of the bottom plate of the device, the main body of the bottom support frame is made of stainless steel metal, and six moving wheels are movably installed at the bottom end of the bottom support frame through a rotating shaft. When in use, the bottom support frame made of stainless steel has better structural strength and load-bearing performance, and multiple moving wheels can drive the device to move quickly to other places.

[0006] Furthermore, two anti-skid supports are fixedly installed on both sides of the bottom plate of the device, and the bottom ends of the anti-skid supports are uniformly provided with anti-skid patterns. When in use, when it is necessary to reduce the vibration of the device, the four anti-skid supports can be activated, and after the anti-skid supports are extended downward, they are completely in contact with the ground, which can significantly reduce a part of the vibration of the device.

[0007] Furthermore, two dust concentration sensors are fixedly installed on the top of the bottom plate of the equipment, and the dust concentration sensors are arranged at the connection between the weighing box and the discharge port. When in use, in order to prevent the coal powder from leaking into the air due to a gap at the connection between the discharge port and the weighing box, a dust concentration sensor is installed near the connection between the discharge port and the weighing box to detect the coal powder concentration.

[0008] Furthermore, a tempered glass observation window is provided in front of the rotor barrel body, and the outer surface of the coal powder rotor mixer and the inner wall of the rotor barrel body are both electroplated with a layer of tungsten steel metal. When in use, the user can observe the rotation of the coal powder inside the rotor barrel body through the tempered glass observation window to prevent the inside of the rotor barrel body from being blocked. At the same time, the tungsten steel metal electroplated on the coal powder rotor mixer and the rotor barrel body can enhance the wear resistance of the equipment.

[0009] Furthermore, the feed port and the rotor barrel body are fixedly connected to each other through a plurality of threaded rods and sealing pads. When in use, the user can separate the feed port and the rotor barrel body by removing the threaded rods of the feed port, and then clean the inside of the feed port to prevent blockage.
