[0002] Calcination is the process of heat treating the catalytic purifier at a relatively high temperature. The purpose of calcination is to remove the volatile components in the catalytic purifier precursor by thermal decomposition, so that the catalytic purifier has stable catalytic purification performance. At the same time, through the solid phase reaction during the high temperature calcination process, the catalytic purifier can obtain a certain shape, particle size, pore structure and specific surface area, increase the stability of the active components of the catalytic purifier, and enhance the mechanical strength.

[0024] An adding unit for adding baking gas is provided inside the housing 1 .

[0025] See also Figure 5 The added component includes a fixed cylinder 5 fixedly mounted on the inner bottom wall of the box body 1 and extending to the interior of the inner cylinder 3, a plurality of stirring blades 6 are fixedly mounted on the surface of the fixed cylinder 5, a plurality of one-way nozzles 7 staggered with the stirring blades 6 are fixedly mounted on the surface of the fixed cylinder 5, a connecting box 9 is also fixedly mounted on the surface of the box body 1, a heating and air supply component for heating the catalytic purifier precursor is arranged inside the connecting box 9, an air inlet pipe 10 is fixedly mounted on the top of the connecting box 9, an air supply pipe 8 connected to the rotating cylinder 4 is fixedly mounted on one side of the connecting box 9, and a connecting pipe 11 for connecting to a roasting gas source is fixedly mounted on the other side of the connecting box 9.

[0026] Among them, by connecting the roasting gas source through the connecting pipe 11, the roasting gas required by the catalytic purifier precursor can be conveniently added to the inside of the box 1 through the one-way nozzle 7. The arrangement of multiple one-way nozzles 7 allows the roasting gas to be distributed more widely when added to the inside of the box 1, and the inner cylinder 3 can be rotated by the driving device, and the gas in the box 1 can be stirred by cooperating with the arrangement of the stirring blades 6, so that the roasting body is distributed more evenly and fully reacts with the catalytic purifier precursor, thereby greatly improving the effect of catalytic purifier roasting.

[0027] See also Figure 3 In this embodiment, the driving assembly includes a motor 20 fixedly mounted on the surface of the housing 1, a rotating shaft 21 extending into the interior of the housing 1 is fixedly mounted on the output end of the motor 20, a bevel gear 22 is fixedly mounted on one end of the rotating shaft 21 located inside the housing 1, and a bevel gear ring 19 meshing with the bevel gear 22 is fixedly mounted on the surface of the rotating drum 4.

[0028] The starter motor 20 drives the bevel gear 22 to rotate, thereby rotating the drum 4 through the bevel gear ring 19, thereby rotating the inner drum 3. When the inner drum 3 rotates, it drives the purified catalyst precursor to rotate, and cooperates with the stirring blades 6 to stir the catalytic purifier precursor.

[0029] The stirring blades 6 can not only stir the catalyst purifier precursor, but also stir the gas environment inside the inner tube 3, so that the roasting gas can be fully mixed and reacted with the catalyst purifier precursor.

[0030] In this embodiment, the stirring blade 6 is hollow and connected to the fixed cylinder 5. A temperature sensor is fixedly installed on the top of the fixed cylinder 5. A controller 14 for controlling the entire device is fixedly installed on the surface of the box body 1. A first solenoid valve 13 is fixedly installed on the surface of the intake pipe 10.

[0034] When it is necessary to add roasting gas, the connecting pipe 11 is connected to the required external gas source, and then the first solenoid valve 13 is closed and the second solenoid valve 12 is opened. Under the action of the fan 16, the roasting gas required for the catalytic purifier precursor is added to the inner tube 3 through the one-way nozzle 7. The setting of multiple one-way nozzles 7 allows the roasting gas to be distributed more deeply when added to the inner tube 3, and the roasting gas in the inner tube 3 can be stirred in conjunction with the setting of the stirring blades 6, so that the roasting gas is distributed more evenly and can fully react with the catalytic purifier precursor, greatly improving the effect of purifying the catalyst roasting.

[0035] In addition, the electric heating wire 15 is used to heat the air, and can also preheat the added roasting gas according to demand, so as to improve the effect of the reaction between the roasting gas and the catalyst purifier precursor.

[0036] In this embodiment, a sealing sleeve 18 is fixedly mounted on the inner bottom wall of the inner cylinder 3 , and the fixed cylinder 5 is rotatably connected to the inner wall of the sealing sleeve 18 .

[0039] The exhaust pipe 23 is used to discharge the flue gas generated when the catalytic purifier is roasted, and the gas purification device 24 is used to filter and purify the flue gas. This is a prior art and will not be described in detail here.

[0040] See also Figure 1 In this embodiment, a first fixing block 25 is fixedly installed on the surface of the box body 1, and a second fixing block 26 is fixedly installed on the surface of the box cover 2. A screw rod 27 is threadedly installed on the inner wall of the second fixing block 26.

The taking out method is not too limited, and the catalytic purifier can also be extracted by an external pump body.

[0042] When the present embodiment is in use, the catalytic purifier precursor is placed inside the inner tube 3, the second solenoid valve 12 is closed, the first solenoid valve 13 is opened, the fan 16 is started to extract the roasting gas and heat it through the electric heating wire 15, and the heated hot air will enter the interior of the fixed tube 5 through the air supply pipe 8, and finally be sprayed out through the one-way nozzle 7 to heat and roast the catalytic purifier precursor. During the roasting process, the motor 20 can be started to drive the bevel gear 22 to rotate, so that the rotating drum 4 can be rotated through the bevel gear ring 19, thereby rotating the inner tube 3. When the inner tube 3 rotates, it will drive the catalytic purifier precursor to rotate, and the stirring blades 6 can be used to stir the catalytic purifier precursor, and at the same time, the hot air can be distributed more evenly in the inner tube 3, thereby improving the efficiency of the catalytic purifier roasting.

[0043] When it is necessary to add other roasting gases, the connecting pipe 11 is connected to the required external gas source, and then the first solenoid valve 13 is closed and the second solenoid valve 12 is opened. Under the action of the fan 16, the roasting gas is added to the inner tube 3 through the one-way nozzle 7. The setting of multiple one-way nozzles 7 allows the roasting gas to be more widely distributed when added to the inner tube 3, and the setting of the stirring blades 6 can stir the gas environment in the inner tube 3, so that the roasting gas is more evenly distributed and can fully react with the catalyst purifier precursor, thereby greatly improving the effect of purifying the catalyst roasting.
