Problems solved by technology

[0004] However, in the above-mentioned dust collector, because the bottom of the box is a tapered structure, the length of the filter bag in the box is reduced, thereby reducing the filter area of ​​the filter bag. During operation, the filter bag is prone to blockage, reducing the filtration efficiency. Frequent dredging is required, which shortens the service life of the filter bag; in addition, in this dust collector, the shape of the filter bag is fixed, and when the filter bag is blocked, the pulse generator is used to dredge it. After some meshes of the bag are dredged, when the air is blown again, the air is generally discharged from the dredged meshes, and it is difficult to act on other parts of the filter bag that have not been dredged, resulting in poor dredging effect of the filter bag. When the equipment is restarted to purify the air , these dredged meshes are easily blocked, which further leads to a short service life of the filter bag, requiring frequent dredging or replacement of the filter bag

Embodiment 1

[0042] like Figure 1-9 As shown, the crusher dust collector of Example 1 includes a casing 1, an exhaust chamber 2 is connected above the casing 1, an air inlet 1-1 is opened on the side wall of the casing 1, and an ash discharge is opened at the bottom Port 1-2, an ash hopper 3 is connected below the ash discharge port 1-2; one end side wall of the exhaust chamber 2 is provided with an exhaust port 2-1, and the other end is connected with a blowing system 10, and the exhaust port 2 -1 is provided with an exhaust valve 4; the shell 1 is cylindrical, and its horizontal cross section is square, the shell 1 is provided with a filter bag 5 that communicates with the exhaust chamber 2, and the filter bag 5 is provided with a deformation support mechanism 6 The bottom of the air inlet 1-1 is provided with a dust-carrying film 7 that is sleeved outside the bottom end of the filter bag 5, and the dust-carrying film 7 is made of latex, and its outer edge passes through the looped fram...

Embodiment 2

[0053] like Figure 10 and Figure 11As shown, the crusher dust collector of Embodiment 2 is based on Embodiment 1, except that the shaping mechanism 8 includes a shaping airbag 8a and a first two-way air pump 8b that communicate with each other. The first bidirectional air pump 8b is fixed on the casing 1 in the synthesized space and connected to the ash-carrying membrane 7 .

[0054] In this embodiment, the first two-way air pump 8b is used to pump air from the shaping airbag 8a, so that the shaping airbag 8b shrinks toward the inner bottom wall and the inner side wall of the housing 1, which drives the shape of the ash-carrying film 7 to change, thereby making the ash-carrying film 7 change its shape. 7 form as Figure 10 The barrel-shaped opening shown is upward, so that a filter bag 5 with a larger filtering area can be placed in the housing 1; The center expands and drives the ash-carrying film 7 to deform, so that the ash-carrying film 7 forms such as Figure 11 In ...

Abstract

The present invention disclosed a crusher dust collector, including the shell and exhaust chamber. The air inlet was opened on the shell, and the bottom was connected to the ash through the gray outlet.The shell is columnar, with a filter bag in the shell; a deformation support mechanism is set inside the filter bag; the ash carrier made of elastic material below the air inlet, the outer edge of the outer edge is connected to the inner wall of the shell to the inner wall connectionInner edge to connect to the ash outlet; the back of the ash to the side of the filter bag is connected to a plastic surgery mechanism. The gray film has two shapes. The first shape is the bucket shape of the opening, and the second shape is a cone -shaped shape.The crusher dust collector can facilitate the length of the filter bag through the cylindrical shell and the first -shaped gray film, thereby expanding the filtration area, enhancing the filtering effect, and extending the use cycle.Falling dust, combined with the blowing system, improve the dredging effect of the filter bag, and adjust the gray film to the second shape to facilitate the gray.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust collector for a crusher. Background technique [0002] Crusher dust collector is a new type of bag filter, suitable for capturing fine, dry, non-fibrous dust, with the advantages of low resistance, simple maintenance and reliable operation. In the dust collector of the crusher, the shell is divided into a filter bag room and a clean air room by a flower plate. The filter bag is arranged under the flower plate and located in the filter bag room. The clean air chamber above the plate communicates. After the dust-laden flue gas enters the filter bag room from the air intake pipe, when passing through the filter bag, the dust is blocked outside the filter bag, and the purified air flows upward in the filter bag, enters the clean air chamber, and then is discharged through the exhaust pipe. [0003] In order to facilitate the falling of dust and impurities into the ash h...
