Embodiment 1

[0042] An airbag-sealed side shot peening structure, comprising:

[0043] A material cylinder 2, a spray gun 2a is installed inside the material cylinder 2;

[0044] The turntable assembly 3, the turntable assembly 3 is rotatably arranged inside the material cylinder 2, the turntable assembly 3 is in the shape of a disc, and there is a gap between the edge of the turntable assembly 3 and the inner wall of the material cylinder 2;

[0045] The rotary driver 4 is fixedly installed on the material cylinder 2, and the output end of the rotary driver 4 is connected to the turntable assembly 3 through transmission;

[0046] Also includes,

[0047] The hollow sealing ring 5 is coaxially installed inside the material cylinder 2, and the hollow sealing ring 5 is arranged between the material cylinder 2 and the turntable assembly 3;

[0048] Filling device (not shown in the figure), the filling device is fixedly installed on the material cylinder 2, and the filling device is used to f...

Embodiment 2

[0093] The difference from Example 1 is:

[0094] One side of the material cylinder 2 is provided with a discharge pipe 2c whose bottom end is flush with the top surface of the turntable assembly 3, and a valve (not shown in the figure) is installed on the discharge pipe 2c.

[0095] Specifically, except for the discharge state, the valve always closes the discharge pipe 2c, so that the material will not be removed through the discharge pipe 2c. When discharging is required, the valve is opened, so that the material can be discharged through the discharge pipe 2c, and the valve It can be a butterfly valve or a cylinder driven piston.

[0096] Working principle of embodiment two:

[0097] Step 1: start the air pump, the air pump fills the hollow sealing ring 5 with gas, and the hollow sealing ring 5 expands to block the gap between the material cylinder 2 and the turntable assembly 3;

[0098] Step 2, the spray gun 2a sprays the material into the material tank 2 until the mat...

Abstract

The invention relates to the field of fluidized beds, in particular to an air bag sealing type side spraying pelleting structure, which comprises a material cylinder, a rotary disc assembly and a rotary driver and further comprises a hollow sealing ring, which is coaxially installed in the material cylinder, and is arranged between the material cylinder and the rotary disc assembly; a filling device,which is fixedly installed on the material cylinder, and is used for filling the interior of the hollow sealing ring so that the hollow sealing ring can block a gap between the material cylinder and the rotary disc assembly after expanding; and an air source, which is communicated with the interior of the material cylinder. The output end of the air source is located below the rotary disc assembly. Through the hollow sealing ring, the filling device and the air source, the technical effect that the turntable does not need to be lifted is achieved, and the technical problems that a turntable in the prior art is complex in structure and high in failure rate are solved.

Description

technical field [0001] The invention relates to the field of fluidized beds, in particular to an airbag-sealed side spray pelletizing structure. Background technique [0002] The side-spray pelletizing structure is a common structure for fluidized bed equipment to deal with the pelletizing and pellet coating process. [0003] Such as figure 1 As shown, the height of the turntable of the traditional structure is adjusted, that is figure 1 The turntable height adjustment mechanism 1 in the middle, when feeding and unloading, the turntable needs to be adjusted to a low position, and the inclined surface of the turntable circle fits the cylinder inclined surface, so that the powder will not fall; when making pellets, the turntable needs to be adjusted to a high position, The inclined surface of the turntable circle is separated from the inclined surface of the cylinder body, and the turntable rotates at a high degree under the drive of the reducer. Because the turntable needs...
