The material to be reacted can be injected into the inner cavity of the reactor shell 21 through the reaction medium inlet 22, so that the material undergoes a chemical reaction in the inner cavity of the reactor shell 21 and is discharged through the reaction medium outlet 23. When the catalyst at the unloading port 27 is being discharged, the electric control valve 2 17 on the left side of the outer wall of the two-way pipe 14 can be closed, and the electric control valve 1 16 on the outer wall of the discharge pipe 15 can be opened at the same time, so that the catalyst is discharged from the discharge pipe 15, and the dust removal cleaning liquid can be injected into the inner cavity of the dust removal box 12 through the water inlet 18.

[0023] like Figure 4 As shown, a feeding pipe 115 is fixedly connected to the left side of the filling box 11, a pump body shell 111 is fixedly installed on the right side of the inner wall of the filling box 11, and a material extraction pump 112 is fixedly installed in the inner cavity of the pump body shell 111.

[0025] like Figure 5 As shown, a filter channel 121 is provided inside the dust removal box 12, and the two-way pipe 14 and the water inlet 18 are both connected to the filter channel 121.

A threaded hole 124 is provided on the front side of the dust removal box 12, and the inner circle of the threaded hole 124 is connected to the inner cavity of the square card slot 122. The inner cavity of the threaded hole 124 is threadedly installed with a threaded cover 125, and a plurality of rotating handles 126 are fixedly installed on the outer wall of the front side of the threaded cover 125 in a circular array, and a square column 127 is movably installed on the rear side of the threaded cover 125.

The three positioning card plates 129 are respectively engaged with the three positioning slots 123.

[0026] When the inner wall of the reactor shell 21 needs to be dusted and cleaned, the liquid extraction pump 13 is started, and the dust removal cleaning liquid in the inner cavity of the filter channel 121 is discharged into the reactor shell 21 through the connection between the water outlet pipe 131 and the loading port 26. Because the feed pipe 113 is connected to the inclined side of the water outlet pipe 131, the cleaning liquid will not enter the feed pipe 113. After the dust removal cleaning liquid is filled in the reactor shell 21, the internal dust and impurities can be mixed. Then, the electric control valve 2 17 is opened and the electric control valve 1 16 is closed, so that the dust removal cleaning liquid mixed with dust and impurities can enter the inner cavity of the filter channel 121. Under the suction of the liquid extraction pipe 132, the water source The three-layer filter screen 128 will filter the dust and impurities so that they adhere to the surface. The filtered cleaning liquid can be used for dust removal and cleaning again. When the filter screen 128 needs to be cleaned, the threaded cover 125 can be rotated by the rotating handle 126 to rotate it in the threaded hole 124 and move it outward until it falls off.

[0027] The working principle of the dust-removable filling machine for the column is described in detail below.

[0028] like Figure 1-5 As shown, when the filling box 11 is filled with catalyst, the catalyst is added to the inner cavity of the filling box 11 through the feeding pipe 115, and then the extraction pump 112 in the pump body shell 111 is started, so that the catalyst in the filling box 11 is sucked into the filling box 11 through the extraction pipe 114, and the catalyst is connected with the feed pipe 113 and the outlet pipe 131 to allow the catalyst to enter the inner cavity of the reactor shell 21 from the loading port 26. At the same time, the catalyst can be replaced through the unloading port 27. The heat exchange medium can be input into the array of tubes in the inner cavity of the reactor shell 21 through the heat exchange medium inlet 24, and the heat exchange medium can be discharged through the heat exchange medium outlet 25. The material to be reacted can be injected into the inner cavity of the reactor shell 21 through the reaction medium inlet 22, so that the material undergoes a chemical reaction in the inner cavity of the reactor shell 21, and then discharged from the reaction medium outlet 23. When the catalyst in the unloading port 27 is discharged, the electric control valve 2 17 on the left side of the outer wall of the two-way pipe 14 can be closed, and the electric control valve 1 16 on the outer wall of the discharge pipe 15 can be opened at the same time, so that the catalyst is discharged from the discharge pipe 15. The dust removal cleaning liquid can be injected into the inner cavity of the dust removal box 12 through the water inlet 18. When the inner wall of the reactor shell 21 needs to be dusted and cleaned, the liquid extraction pump 13 can be started to use the suction pump 13 to remove the dust. The liquid pipe 132 discharges the dust removal cleaning liquid in the inner cavity of the filter channel 121 into the reactor shell 21 by connecting the outlet pipe 131 with the loading port 26. Because the feed pipe 113 is connected to the inclined side of the outlet pipe 131, the cleaning liquid will not enter the feed pipe 113. After the dust removal cleaning liquid is filled in the reactor shell 21, the internal dust and impurities can be mixed. Then, the electric control valve 2 17 is opened and the electric control valve 1 16 is closed, so that the dust removal cleaning liquid mixed with dust and impurities can enter the inner cavity of the filter channel 121. Under the suction of the liquid extraction pipe 132, the water source will pass through the three-layer filter screen plate 128 for filtration. , so that dust and impurities adhere to its surface, and the filtered cleaning liquid can be used for dust removal and cleaning again. When the filter screen plate 128 needs to be cleaned, it is only necessary to use the rotating handle 126 to rotate the threaded cover 125 to rotate it in the threaded hole 124 and move it outward until it falls off, and then the square column 127 can be pulled out of the filter screen plate 128. After cleaning, it is only necessary to align the three positioning card plates 129 with the three positioning grooves 123 for installation, and make the square column 127 be inserted into the square card groove 122, so that the filter screen plate 128 is exactly located in the inner cavity of the filter channel 121, and then rotate and tighten the threaded cover 125.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
