Description

Technical Field

[0001] The utility model relates to the field of bag dust collectors. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of filter cloth woven from fiber fabric materials or non-woven felt. The filter bag uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

Implementation

[0020] like Figure 1 As shown, a detachable ash storage bucket, the upper cover body 1 is detachably covered on the lower cylinder 2, the upper cover body 1 has a central tube for connecting the dust outlet of the bag dust collector, the central tube is connected to the interior of the covered lower cylinder 2, when the ash discharge valve of the bag dust collector is opened, the dust enters the lower cylinder 2 through the central tube. In one embodiment, the upper cover body 1 is a circular plate, the central tube at the center of its upper part is integrally connected to the upper cover body 1 or flange-connected, and the central tube is connected to the dust outlet of the bag dust collector through a flange. In order to reinforce the central tube, the central tube and the upper surface of the upper cover body 1 are reinforced by a rib plate.

[0021] like Figure 1 and Figure 2 As shown, there are two first side ears 4 on the outer side of the upper surface of the upper cover body 1. In one embodiment, each first side ear 4 is a rectangular parallelepiped structure, and each first side ear 4 is fixed on the upper surface of the edge of the upper cover body 1, so that the lower surface of the upper cover body 1 is easy to form a seal with the mouth of the lower cylinder 2. In another embodiment, it can also be prepared that the radius of the upper cover body 1 is equal to the outer diameter of the lower cylinder 2, the first side ear 4 and the upper cover body 1 are in the same horizontal plane, and the first side ear 4 is connected to the outer circle of the upper cover body 1. The connecting line of the two first side ears 4 intersects with the central axis of the upper cover body 1, and there are two second side ears 7 on the outer side of the upper part (mouth) of the lower cylinder 2, and the connecting line of the two second side ears 7 intersects with the central axis of the lower cylinder 2. There are two mop handles on the outer side of the upper part of the lower cylinder 2, and the connecting line of the two mop handles intersects with the central axis of the lower cylinder 2 and is symmetrical about the connecting line of the two second side ears 7. The two mop handles are used to drag the separated lower cylinder 2. The levels of the two second side ears 7 and the upper surfaces of the two mop handles are lower than the level of the mouth of the lower cylinder 2. In one embodiment, the upper cover 1 has a rubber ring at a position corresponding to the mouth of the lower cylinder 2 (when closed), and the lower surface of the rubber ring is a plane, so that when closed, the upper cover 1 and the lower cylinder 2 can be effectively sealed.

[0022] When the upper cover 1 is covered on the lower cylinder 2, each first side ear 4 corresponds to a second side ear 7 in the vertical direction. The upper surface of the second side ear 7 is a plane, and the second side ear 7 is a semi-inverted cone, which can ensure that the connection between the second side ear 7 and the lower cylinder 2 will not loosen. The second side ear 7 can also be other shapes, as long as it can ensure a tight connection with the outer wall of the lower cylinder 2 and can accommodate the connecting counterbore 71 and the annular expansion cavity 72.

[0023] like Figure 3-8As shown, each first side ear 4 has a first cavity 41 inside, and the first cavity 41 is a short rectangular structure. In each first cavity 41, there are two shaft supports 42 fixed to the inner wall of the first cavity 41, and the shaft support 42 is a device fixed to the lower cylinder 2. In one embodiment, the shaft support 42 is a rectangular parallelepiped, and the upper surface and / or lower surface of the shaft support 42 is fixed to the lower cylinder 2. Each shaft support 42 has an shaft countersunk hole, and the two ends of the transverse axis 5 are respectively located in a shaft countersunk hole, and the shaft countersunk hole is a support for installing the transverse axis 5. The transverse axis 5 can rotate in the shaft countersunk hole. A transverse gear 51 is fixedly installed in the center of the transverse axis 5. In the present invention, the central axis of the transverse gear 51 is parallel to the horizontal plane. A point in the center of the periphery of each transverse gear 51 is connected (can be welded or integrally connected) to the handle end 31 at one end of the annular handle 3, and each first side ear 4 has an annular slit 43, which is perpendicular to the transverse axis 5, and each end of the annular handle 3 is in an annular slit 43. The purpose of the annular slit 43 on the first side ear 4 is to enable the annular handle 3 to be reversed along the annular slit 43, thereby rotating the transverse axis 5.

[0024] Each first side ear 4 has a longitudinal shaft 6, which passes through the first cavity 41 from top to bottom. The longitudinal shaft 6 is fixedly connected to the portion of the longitudinal shaft 6 inside the first cavity 41 with a longitudinal gear 61, which meshes with the transverse gear 51. A stopper 63 is provided at the lower portion of the longitudinal shaft 6. When the transverse shaft 5 rotates, the longitudinal gear 61 is driven to rotate, so that the stopper 63 rotates around the central axis of the longitudinal shaft 6.

[0025] Each second side ear 7 has a connecting counterbore 71, the bottom of the connecting counterbore 71 has an annular expansion cavity 72, the peripheral side of the connecting counterbore 71 has a vertical fan-shaped slit 73, the radius of the longitudinal axis 6 is less than or equal to the inner diameter of the connecting counterbore 71, the maximum distance from the stopper 63 to the central axis of the longitudinal axis 6 is greater than the inner diameter of the connecting counterbore 71, the maximum distance from the stopper 63 to the central axis of the longitudinal axis 6 is less than or equal to the maximum distance from the annular expansion cavity 72 to the central axis of the connecting counterbore 71, and the maximum distance from the stopper 63 to the central axis of the longitudinal axis 6 is less than or equal to the maximum distance from the annular expansion cavity 72 to the central axis of the connecting counterbore 71, and the maximum distance from the stopper 63 to the central axis of the longitudinal axis 6 is less than or equal to the maximum distance from the annular slit 43 to the central axis of the connecting counterbore 71. When the annular handle 3 is in a vertical state, the center of the stopper 63 on the longitudinal axis 6 vertically corresponds to the center of the fan-shaped slit 73 of the connecting counterbore 71.

[0026] When the stopper 63 is a fan-shaped cone block, the central angle α of the cross section of the stopper 63 is 15-30°; the cross section of the fan-shaped slot 73 is a fan-shaped cone block, and the central angle of the cross section of the fan-shaped slot 73 is 20-40°.

[0027] When the upper cover 1 is covered on the lower cylinder 2, the end of the longitudinal axis 6 extends into the connecting counterbore 71. Due to the presence of the fan-shaped slit 73, the stopper 63 enters the annular expansion cavity 72 from the fan-shaped slit 73. When the longitudinal axis 6 rotates, the fan-shaped slit 73 and the stopper 63 are no longer aligned. At this time, the stopper 63 prevents the longitudinal axis 6 from leaving the connecting counterbore 71. The stopper 63 is a fan-shaped cone block, which can effectively ensure the sealing of the two (the upper cover and the lower cylinder) during rotation, and avoid the problem that the upper surface of the stopper is flat and cannot be rotated due to insufficient insertion.

[0028] There are wheels at the bottom of the lower cylinder 2, so that the lower cylinder 2 can be moved easily.
