DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1:

[0026] Reference Figure 1-5 A filtering device for solid catalysts, comprising a tank body 1, on which a feed port 102 is arranged, and further comprising: four sets of mounting rings 201, all of which are fixedly connected to the tank body 1; multiple sets of spring members 202, all of which are connected to the mounting rings 201; a filter screen 1 203, a filter screen 204, a filter screen 3 205, and a filter screen 4 206, which are sequentially connected to the spring members 202 of the four sets of mounting rings 201 from top to bottom, the filter screen 1 203, the filter screen 204, the filter screen 3 205, and the filter screen 4 206 are consistent with the inner diameter of the tank body 1, and the filter hole sizes decrease sequentially from top to bottom; multiple sets of rotating doors 10 1, are all rotatably connected to the tank body 1, the rotating door 101 is used to take out the catalyst located on the filter screen, a telescopic motor 4 is fixedly connected to the tank body 1, the telescopic end of the telescopic motor 4 is used to knock the uppermost filter screen 203, the bottoms of the filter screens 1 203, 204, 205 are all fixedly connected with auxiliary rods 403, the auxiliary rods 403 are used to squeeze the filters below, the filter screens 1 203, 204, 205, 206 are all fixedly connected with knocking plates 402, and the knocking plates 402 are respectively located below the knocking rod 401 and the auxiliary rod 403.

[0027] like Figure 2 As shown, the filters are arranged at equal intervals from top to bottom, and the top filter hole is the largest, and the bottom filter hole is the smallest. At this time, the solid catalyst to be filtered is poured into the feed port 102. At this time, after the fixed catalyst is poured in, it will contact the top filter screen 203, and then the catalyst will jump on the filter screen 203. Small particles of catalyst will fall onto the filter screen 204 below, and the larger ones will remain on the filter screen 203. The same is true for the bottom. In this way, the catalyst can be classified. After the classification is completed, the rotating door 101 can be opened to take out the catalyst on the filter screen, and the finest powdered catalyst will be left at the bottom of the tank 1.

[0028] At this point, catalysts of different particle sizes can be obtained, and the specific size can be determined by selecting filters with different mesh sizes according to demand, so that the catalyst of the required size can be obtained.

[0029] When in use, in order to facilitate the classification and filtering of the catalyst, the telescopic motor 4 can be started, so that the telescopic end of the telescopic motor 4 continuously and intermittently squeezes the knocking plate 402 on the filter screen 203 below, and at the same time, the filter screen 203 moves downward, so that the auxiliary rod 403 knocks the filter screen 204 below, and this cycle is repeated until the filter screen 4 206 also vibrates up and down. At this time, the classification and filtering of the catalyst on the filter can be achieved.

[0030] Embodiment 2:

[0031] Reference Figure 1-5 , a filtering device for solid catalyst, which is basically the same as Example 1, and further includes: a water tank 3, an air pump 301 is connected to the water tank 3, an air inlet pipe 302 is connected to the air inlet end of the air pump 301, and the air inlet pipe 302 is communicated with the interior of the tank body 1.

[0032] During use, due to vibration and other reasons, some powder will diffuse in the air. At this time, the air pump 301 is started to adsorb the powder diffused in the air, and then discharged through the air outlet to enter the water tank 3 and contact with water. At this time, the powdered catalyst will contact with water and then mix with water. The subsequent gas will be discharged through the top and contact with the outside world. Some catalysts that are insoluble in water may be discharged with the gas. Therefore, when using, attention should be paid to the specific type of catalyst.

[0033] Embodiment 3:

[0034] Reference Figure 1-3 , a filtering device for solid catalyst, which is basically the same as Example 1, and further: a plurality of groups of liquid outlets 103 are arranged at the bottom of the tank body 1 along the circumferential inclination, and a liquid inlet pipe 104 is connected to the tank body 1, and the liquid inlet pipe 104 is communicated with the liquid outlet 103.

[0035] By setting the liquid outlet 103, after use, the rotating door 101 is closed, and the catalyst remaining in the tank body 1 is dissolved by the continuously formed vortex water flow, which is convenient for cleaning, and the water-insoluble catalyst cannot be used.

[0036] The utility model can filter the catalyst by setting the filter screens with various mesh sizes, filter and screen out the unsuitable catalyst, and then obtain the catalyst of the required size, which can be used in fine chemical industry.

[0037] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
