Description

Technical Field

[0001] The utility model relates to the technical field of dust removal pipes, in particular to an end interface of a dust removal pipe with a collection function. Background Art

[0002] The dust removal duct system effectively encloses the silo discharge area by using powerful dust suction. A top suction hood is installed above the silo discharge port, and a duct is installed at the top of the top suction hood for powerful dust suction.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1:

[0020] A dust removal pipe end interface with a collection function, comprising a fixed pipe body 1, a lower speaker housing body 2, an air volume regulator 3, an upper speaker housing body 4 and an air flow baffle 5. The upper end of the fixed pipe body 1 is provided with a lower speaker housing body 2, and the interior of the lower speaker housing body 2 is provided with an air flow baffle 5. Figure 4 As shown, an air volume regulator 3 is provided at the upper end of the fixed tube body 1, and an upper speaker mask body 4 is provided at the bottom end of the air volume regulator 3, and the upper speaker mask body 4 is covered at the upper port of the lower speaker mask body 2, and a first annular air channel 401 is formed between the port of the upper speaker mask body 4 and the port of the lower speaker mask body 2. The bottom end of the fixed tube body 1 is connected to the upper end of the top suction hood in the area where dust removal is required. Since a first annular air channel 401 is left between the upper speaker mask body 4 and the lower speaker mask body 2, the gap between the upper speaker mask body 4 and the lower speaker mask body 2 can be adjusted by controlling the lifting and lowering of the upper speaker mask body 4, thereby changing the gap in the first annular air channel 401 and changing the size of the air intake at the first annular air channel 401, and then changing the air pressure difference between the top of the lower speaker mask body 2 and the bottom end of the fixed tube body 1. The negative pressure difference can be adjusted according to the particulate material to avoid small particulate materials being sucked out and wasted due to excessive air pressure difference.

[0021] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: the utility model controls the lifting and lowering of the upper speaker mask body 4, adjusts the distance between the upper speaker mask body 4 and the lower speaker mask body 2, changes the gap of the first annular air channel 401, and thus changes the size of the air intake at the first annular air channel 401, and then changes the air pressure difference between the top of the lower speaker mask body 2 and the bottom of the fixed tube body 1. The negative pressure difference can be adjusted according to the particulate material to avoid small particulate materials being sucked out and wasted due to excessive air pressure difference. Example 2:

[0022] like Figure 4 As shown, the airflow baffle 5 includes a connecting ring 501, which is connected to the inner wall of the fixed tube body 1 through a thread. The middle part of the connecting ring 501 is a coarse filter plate 502, and the middle part of the coarse filter plate 502 is provided with an inner thread seat 5021. The inner thread seat 5021 is connected to a shaft 503. The upper end of the shaft 503 is connected to a blocking plate 504. The blocking plate 504 is an umbrella-shaped pleated cover. When the air carrying dust or a small amount of material is guided from bottom to top along the fixed tube body 1, the airflow is blocked at the blocking plate 504. Under the obstruction, according to the principle of particle kinematics, large particles of material gather and sink in the middle of the axis of the upper trumpet mask body 4, while small particles of impurities such as dust are sucked out upward along the air volume regulator 3; a return port 5041 is opened on the outer periphery of the blocking plate 504 and corresponding to each wrinkled edge, so that the particle material that sinks in the middle of the upper trumpet mask body 4 is guided downward; large particles of material gather and sink at the upper end of the fixed tube body 1 close to the inner wall, and a return trough 5022 is opened on the outer periphery of the coarse filter plate 502 for guiding the material down.

[0023] The surface of the coarse filter plate 502 is provided with evenly distributed sieve holes for the particulate materials. In the suction airflow on the fixed pipe body 1, the particulate materials are initially partially screened to prevent large particles from being sucked out.

[0024] A screw portion is provided at the bottom of the shaft rod 503, and the threaded rod portion at the bottom of the shaft rod 503 is threadedly connected to the inner thread seat 5021. A hexagonal turn head 5031 is provided at the bottom end of the shaft rod 503. A second annular air channel is left between the cover edge of the blocking plate 504 and the inner wall of the lower horn cover body 2. By rotating the hexagonal turn head 5031, the gap of the second annular air channel can be adjusted according to the size of the particulate material.

[0025] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: when the air carrying dust or a small amount of material is guided from bottom to top along the fixed pipe body 1, the airflow is blocked by the blocking plate 504. According to the principle of particle kinematics, large particles of material gather and sink in the middle of the axis of the upper speaker cover body 4, while small particles of impurities such as dust are sucked out upward along the air volume regulator 3.

[0026] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
