DETAILED DESCRIPTION

[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] Embodiment 1

[0029] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 2 As shown, a safe portable dust collecting device includes a material guiding mechanism, a material receiving structure and a protective mechanism.

[0030] The material guiding mechanism comprises a first material guiding trough 1 , the top and bottom of the first material guiding trough 1 are both open, the top opening size is larger than the bottom opening size, and the dust enters the first material guiding trough 1 through the top opening of the first material guiding trough 1 .

[0031] The bottom of the first guide trough is connected to the second guide trough 12 through an ash discharge valve. Figure 2 As shown, the top and bottom ends of the second material guiding trough are both open, and the cross-section of the second material guiding trough is square.

[0032] The top inlet of the ash discharge valve is connected to the bottom opening of the first material guide trough, and the bottom outlet of the ash discharge valve is connected to the top opening of the second material guide trough 12, ensuring that the dust enters the receiving bucket 10 smoothly and does not overflow during the falling process. The ash discharge valve adopts a star-shaped ash discharge valve 3. A photoelectric switch 4 is provided on the star-shaped ash discharge valve 3, which is used to detect the action state of the ash discharge valve in real time to determine whether blockage occurs. The star-shaped ash discharge valve 3 is used to control the discharge of dust, ensure that the dust is discharged evenly, and prevent dust accumulation.

[0033] The first material guiding trough is provided with a compressed air blowing mechanism for periodically blowing the inner side surface of the first material guiding trough 1 to reduce the risk of blockage.

[0034] The material receiving mechanism includes a material receiving bucket 10 , which is arranged below the bottom outlet of the second material guiding trough 12 . After the dust is unloaded by the star-shaped dust unloading valve 3 , the dust enters the material receiving bucket 10 through the bottom outlet of the second material guiding trough 12 .

[0035] Specifically, the tobacco dust collection bag is fixed at the top of the material receiving barrel 10 by the edge pressing ring 8 to ensure that the bag does not shift or fall off. When the tobacco dust collection bag is full of dust, the edge pressing ring 8 is removed and the tobacco dust collection bag on the material receiving barrel 10 can be replaced.

[0036] like Figure 2 As shown, a receiving bucket handle 9 is provided on the outer side wall of the receiving bucket 10 , and a universal wheel 11 is provided at the bottom, so that the receiving bucket 10 can be conveniently moved by pulling the receiving bucket handle 9 .

[0037] In order to prevent dust from falling through the bottom opening of the second material guide chute when replacing a new tobacco dust collection bag, a slide groove is transversely provided at the bottom opening of the second material guide chute, and a plug plate 7 is slidably installed on the slide groove. The plug plate 7 is slidably arranged along the slide groove to close the bottom opening of the second material guide chute 12. The plug plate 7 is used to be inserted when replacing the tobacco dust collection bag in the receiving barrel 10 to prevent dust from falling further, thereby ensuring cleanliness and safety during the replacement process.

[0038] When it is necessary to replace the tobacco dust collecting bag on the receiving barrel 10, first insert the plug plate 7 into the slide groove so that the plug plate 7 closes the bottom opening of the second material guide groove, and then pull out the receiving barrel 10 to replace the tobacco dust collecting bag. After replacing the tobacco dust collecting bag, push the receiving barrel 10 back under the bottom opening of the second material guide groove, remove the plug plate 7 to continue collecting dust.

[0039] Considering that dust may overflow when falling through the bottom opening of the second material guide trough to the receiving bucket 10, a protective mechanism is provided, such as Figure 1 and Figure 2 As shown, the protection mechanism is used to cover the outside of the material receiving mechanism to prevent dust from overflowing and leaking, and also plays a protective role. The protection mechanism includes a protection shell 6, and an openable observation window 5 is provided on one side of the protection shell 6.

[0040] like Figure 2As shown, the protective housing 6 is surrounded by four plate-like structures to form a housing structure with two openings at both ends and a rectangular cross-section, and one side of the plate-like structure with the observation window 5 is hinged to the adjacent plate-like structure and used as a switch door, and the other side of the adjacent plate-like structure can be provided with a locking structure, and the locking structure is not limited, as long as it can achieve locking of the plate-like structure with the observation window 5. The dust collection condition of the receiving bucket 10 inside the protective housing 6 can be observed through the observation window 5 to ensure the normal operation of the equipment.

[0041] It is understandable that the top opening size of the protective shell 6 is adapted to the bottom size of the second material guide trough 12, and the top edge of the protective shell 6 and the bottom opening of the second material guide trough 12 can be fixedly connected by a flanging structure and bolts and nuts.

[0042] like Figure 1 As shown, the first material guide trough of this embodiment is an inverted tetrahedral structure, and the compressed air blowing mechanism 2 includes an annular pipeline 21, which is sleeved on the outside of the first material guide trough 1, and the inner side of the annular pipeline is connected to the inner side of the first material guide trough 1 through a plurality of connecting pipes 22 and is provided with an air nozzle. The inner side of the annular pipeline of this embodiment is connected to the inner side of the first material guide trough 1 through four connecting pipes 22, and each side of the tetrahedral structure is correspondingly provided with a group of connecting pipes 22.

[0043] Specifically, the connecting pipe penetrates the side wall of the first material guide groove, a sealing ring is arranged between the connecting pipe and the side wall of the first material guide groove, and the jetting direction of the air nozzle is preferably arranged downward or obliquely downward along the side wall of the first material guide groove. It can be understood that the annular pipeline is also connected to the gas source.

[0044] The annular pipeline is provided with high-pressure gas through an air source, and the high-pressure gas reaches the inner side of the first material guide trough through a connecting pipe and is ejected through an air nozzle to achieve soot blowing on the inner side of the first material guide trough, thereby reducing the risk of blockage of the bottom opening of the first material guide trough.

[0045] The photoelectric switch 4 of this embodiment is installed on the star-shaped ash discharge valve 3, and is used to detect the operating state of the star-shaped ash discharge valve 3 in real time to determine whether material blockage occurs. When an abnormality is detected, the photoelectric switch will sound an alarm to remind the operator to perform maintenance.

[0046] The controller 13 is connected to the photoelectric switch 4 and the compressed air blowing mechanism 2 through a signal line. According to the judgment of the photoelectric switch 4 on the material blocking situation, the blowing force of the compressed air blowing mechanism 2 can be adjusted to effectively improve the blowing efficiency. It can be understood that there is an ash discharge valve under the first material guide trough to play an air locking role, and the entire space is closed, so the dust at the first material guide trough will not overflow.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
