Technical Field

[0001] The invention belongs to the technical field of powder processing, and in particular relates to a catheter device for powder processing with anti-blocking and foreign body discharge functions. Background Art

[0002] During the calcination process of magnesium oxide powder, block-shaped foreign matter sometimes falls from the calcination furnace. If these foreign matter are not discharged from the pipeline in time, the cross-sectional area of ​​the pipeline will become smaller and smaller, thereby increasing the pipeline resistance, thereby causing a decrease in the output of magnesium oxide powder. In severe cases, the pipeline may even be completely blocked. At this time, production can only be stopped and the pipeline unblocked, which will ultimately affect the stability and efficiency of the calcination preparation of magnesium oxide powder.

[0013] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a catheter device with anti-blocking and foreign body removal functions for powder processing includes an air inlet pipe 1, an intermediate pipe 2, an air outlet pipe 3, a collecting bucket 4, a check valve 5 and a discharge pipe 6; the air inlet pipe 1 is arranged obliquely, and the upper end of the air inlet pipe 1 is used to receive the dust-containing gas; the intermediate pipe 2 is arranged horizontally, and the pipe opening at one end of the intermediate pipe 2 is sealed and connected with the lower end of the air inlet pipe 1; the air outlet pipe 3 is arranged vertically, and the lower end of the air outlet pipe 3 is sealed and connected with the other end of the intermediate pipe 2. The upper end of the pipe is sealed and connected to the roasting furnace; the collecting bucket 4 is located below the intermediate pipe 2 and the air outlet pipe 3, and the collecting bucket 4 is sealed and connected to the intermediate pipe 2 and the air outlet pipe 3; the check valve 5 is located below the collecting bucket 4, the check valve 5 is vertically arranged, and the upper end valve port of the check valve 5 is sealed and connected to the bottom outlet of the collecting bucket 4; the discharge pipe 6 is located below the check valve 5, the discharge pipe 6 is vertically arranged, the upper end pipe port of the discharge pipe 6 is sealed and connected to the lower end valve port of the check valve 5, and the lower end pipe port of the discharge pipe 6 is connected to the collecting box.

[0015] The cone surface inclination angle of the collecting hopper 4 is not less than 45°, so that the block-shaped foreign matter dropped from the roasting furnace will not adhere to the cone surface side wall of the collecting hopper 4, but will directly slide into the check valve 5 at the bottom of the collecting hopper 4.

[0016] The check valve 5 adopts a self-opening structure, including a valve housing 7 and a valve core 8. A guide limit plate 9 is fixedly arranged inside the valve housing 7. The guide limit plate 9 adopts a semicircular structure and is arranged to be tilted downward; the valve core 8 adopts a semicircular structure, the straight edge of the valve core 8 is hinged to the straight edge of the guide limit plate 9, and the straight edge of the valve core 8 is externally connected to a counterweight block 10, and the counterweight block 10 is located below the guide limit plate 9; in the initial state, the valve core 8 is in a horizontal posture, and the check valve 5 is in a closed state; when the self-weight of foreign matter accumulated on the valve core 8 exceeds the reaction force exerted by the counterweight block 10, the valve core 8 flips downward, and the check valve 5 is in an open state.

[0017] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings:

[0018] When the roasting furnace is in operation, it will continuously generate high negative pressure, and the dust-containing gas will be sucked into the roasting furnace through the air inlet pipe 1, the intermediate pipe 2 and the air outlet pipe 3 in sequence under the high negative pressure. In this process, although the angle between the air inlet pipe 1 and the air outlet pipe 3 is relatively small, the existence of the intermediate pipe 2 can effectively reduce the resistance of the dust-containing gas in the process of entering the air outlet pipe 3 from the air inlet pipe 1, ensuring that most of the magnesium oxide dust can enter the roasting furnace with the dust-containing gas, and only a very small amount of magnesium oxide dust will fall into the collection bucket 4. At the same time, under the high negative pressure generated by the roasting furnace, a small amount of air will be sucked in through the check valve 5, and this air will have a secondary lifting effect on the dust in the collection bucket 4 during the inhalation process, and then be sucked back into the roasting furnace.

[0019] As the roasting furnace is running, the block foreign matter in the roasting furnace will fall under the influence of gravity, and directly fall into the check valve 5 at the bottom of the collection bucket 4 through the air outlet pipe 3, and gradually accumulate on the valve core 8. As the amount of block foreign matter accumulates, until the self-weight of the block foreign matter exceeds the reaction force applied by the counterweight 10, the valve core 8 begins to flip downward, the check valve 5 is automatically opened, and the foreign matter accumulated on the valve core 8 can smoothly pass through the check valve 5 and fall into the discharge pipe 6 below, and finally be discharged from the discharge pipe 6 to the collection box for unified storage. As the foreign matter is discharged, the reaction applied by the counterweight 10 resumes its effect, and pulls the valve core 8 back to the horizontal posture under the action of the lever, so that the check valve 5 returns to the closed state again.

[0020] The solutions in the embodiments are not intended to limit the patent protection scope of the present invention. All equivalent implementations or changes that do not deviate from the present invention are included in the patent scope of this case.
