[0023] Reference Figure 1-Figure 4 A detachable negative pressure suction pneumatic conveying device comprises a material tank 7, a negative pressure pump 1 is fixed to the top outer wall of the material tank 7 by bolts, a connecting pipe 2 is connected and fixed to one side of the material tank 7, and one end of the air inlet of the negative pressure pump 1 is connected to the material tank 7, a shell 3 is installed at the bottom end of the connecting pipe 2, a feed pipe 4 is connected to the bottom of the shell 3, an inner shell 6 is connected to the bottom end of the feed pipe 4, an outer shell 5 is sleeved on the outer side of the inner shell 6, and the inner shell 6 and the outer shell 5 are fixed by a connecting assembly, an inclined plate 11 is obliquely installed on the inner wall of the shell 3, a plurality of through holes 13 are opened inside the inclined plate 11, and the negative pressure pump 1 makes the material tank 7 Negative pressure is generated, and the external powder enters the shell 3 through the feed pipe 4. The through hole 13 on the baffle 12 filters the powder, so that the larger particles of material are filtered to the bottom of the baffle 12. Since the baffle 12 is designed to be inclined, the larger particles of material move upward along the slope of the baffle 12 under the action of suction, so it will not affect the normal powder transportation. An openable partition component is provided on the top of the inner shell 6. When the transportation is completed or there are more larger particles of material accumulated at the bottom of the baffle 12, the negative pressure pump 1 is stopped. At this time, the accumulated larger particles of material fall downward to the top of the partition component.

[0024] In the present invention, it should be noted that the connecting component includes two L-shaped plates 10, which are respectively fixed to the outer walls of both sides of the inner shell 6 by bolts, and the internal threads of the L-shaped plates 10 are connected with threaded rods 8, one end of the threaded rods 8 is rotatably connected with a clamping block 9, and the clamping block 9 contacts the top outer wall of the inner shell 6, and the threaded rods 8 are rotated to move the clamping block 9 until it is separated from the top of the inner shell 6, and then the outer shell 5 is moved downward to separate it from the inner shell 6, so as to facilitate the staff to centrally process the collected materials, and the partition component includes a plurality of fixed plates 15, and the plurality of fixed plates 15 are symmetrically fixed on the bottom inner wall of the inner shell 6, and a connecting shaft 19 is rotatably connected between the two fixed plates 15, and a baffle 12 is fixed to the outer side of the connecting shaft 19 by bolts, and both ends of the connecting shaft 19 are sleeved with torsion springs 14, and the two ends of the torsion spring 14 are respectively connected to the connecting shaft 19 and the fixed plate 19. The fixed plates 15 are fixed, and the two baffles 12 are closed and contacted to completely block the feed opening at the top of the inner shell 6. The top inner wall of the inner shell 6 is fixed with a protrusion 18 by bolts, and an electric telescopic rod 17 is fixed with a bracket 16 by bolts on one side of the protrusion 18. The extended end of the electric telescopic rod 17 is fixed with a bracket 16 by bolts, and the bracket 16 is in contact with the bottom of the baffle 12. The electric telescopic rod 17 is started, and the electric telescopic rod 17 contracts to separate the bracket 16 from the baffle 12. At this time, under the action of the gravity of the baffle 12 and the gravity of the material, the torsion spring 14 is deformed, causing the baffle 12 to rotate downward and open. At this time, larger particles of material enter the inner shell 6 and fall to the bottom of the outer shell 5, thereby facilitating the collection and processing of larger particles of material. A rubber pad is bonded to the bottom of the block 9, and one end of the threaded rod 8 passes through the L-shaped plate 10 and is welded with a knob to facilitate the staff to rotate the threaded rod 8.

At this time, the external powder enters the shell 3 through the feed pipe 4, and the through hole 13 on the baffle 12 filters the powder, so that the larger particles of material are filtered to the bottom of the baffle 12. When the transportation is completed or there are a lot of larger particles of material accumulated at the bottom of the baffle 12, stop the negative pressure pump 1. At this time, the accumulated larger particles of material fall down into the baffle 12, and then start the electric telescopic rod 17. The electric telescopic rod 17 contracts to separate the bracket 16 from the baffle 12. At this time, under the action of the gravity of the baffle 12 and the gravity of the material, the torsion spring 14 is deformed, causing the baffle 12 to rotate downward and open. At this time, the larger particles of material enter the inner shell 6 and fall to the bottom of the outer shell 5, which facilitates the collection and processing of the larger particles of material.
