Description
Technical Field
The invention belongs to the technical field of catalyst filling, and particularly relates to a dense-phase filling device.
Background
Dense phase loader is a common catalyst filling equipment in chemical production, however in the process of filling, because the catalyst can be broken and produce the dust, because the dust is very light, it is difficult to throw away the dust again singly through the rotation of cloth charging tray, can cause more catalyst breakage in the process of filling after the dust has been too much to the dust still probably falls in the central point of reactor, influences catalytic reaction effect.
Disclosure of Invention
The invention aims to provide a dense-phase filling device which can recycle nitrogen in the discharging process.
In order to achieve the purpose, the invention provides the following technical scheme:
a dense phase packing apparatus comprising: the device comprises a cylinder, a driving device and a cloth disc; the driving device is arranged below the cylinder body, and the material distribution disc is connected with the driving device; the cloth dish is the hemisphere face structure, is equipped with a plurality of discharge gates on the lateral wall of cloth dish, is equipped with guide vane towards cloth dish inside around the discharge gate, is equipped with the admission nozzle on the lateral wall of barrel.
Furthermore, the driving device is a motor, and a rotating shaft of the motor is fixedly connected with a rotating shaft of the cloth disc.
Furthermore, a support is arranged at the lower end of the cylinder body, and the cylinder body is fixed on the support.
Furthermore, the discharge hole is in an inverted trapezoid shape.
Further, the air inlet nozzle is close to the lower end of the cylinder body.
Furthermore, a flow control valve is arranged at the top of the cylinder body.
The beneficial technical effects are as follows: the invention drives the guide vane to assist the material distribution disc to rotate by air inlet of the air inlet nozzle, and can blow out dust from the material outlet through high-speed gas flow, thereby preventing the dust from falling to the center of the reactor and simultaneously reducing the breakage rate of the catalyst.
Drawings
FIG. 1 is a schematic diagram of the dense phase packing apparatus of the present invention;
fig. 2 is a top view of the cloth tray of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the present invention provides a dense phase packing apparatus comprising: the device comprises a cylinder 1, a driving device 2 and a cloth disc 3; the driving device 2 is arranged below the barrel 1, and the material distribution disc 3 is connected with the driving device 2; the cloth 3 dish is the hemisphere face structure, is equipped with a plurality of discharge gates 31 on the lateral wall of cloth dish 3, is equipped with guide vane 32 around discharge gate 31 towards cloth dish inside, is equipped with inlet nozzle 4 on the lateral wall of barrel 1.
The driving device 3 is a motor, and a rotating shaft of the motor is fixedly connected with a rotating shaft of the cloth disc 3.
The lower end of the cylinder body 1 is also provided with a bracket 5, and the cylinder body is fixed on the bracket 5.
The discharge hole is in an inverted trapezoid shape.
The air inlet nozzle 5 is close to the lower end of the cylinder body 1.
The top of the cylinder 1 is also provided with a flow control valve 6.
The working principle is as follows: when the device is used, the material is discharged from the top end of the barrel body 1, the speed of the discharged material is adjusted through the flow control valve 6, meanwhile, the material distribution disk 3 is driven to rotate through the motor, meanwhile, the air inlet nozzle 4 is connected into an external compressed air source to blow air into the barrel body 1, the rotation of the material distribution disk 3 is assisted, meanwhile, dust generated by crushing the catalyst is blown out, the catalyst is thrown out of the material distribution disk along a flow channel formed by the guide blades 32, and a radial grading filling method can be adopted during material distribution, so that the central part of the reactor is filled with low density, and the opposite wall part of the. The catalyst fine dust is not dropped to the center of the reactor as much as possible.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
