Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and more particularly to a bag dust collector which is easy to repair. Background Art

[0002] Dust collectors are devices that separate dust from flue gases and are commonly used in boilers and other industrial production facilities. Industrial dust collectors are generally used outdoors and are relatively large. When a dust collector malfunctions or requires regular maintenance, a lift is required to lift the operator, making maintenance quite inconvenient. Therefore, further improvements are needed for these large outdoor dust collectors. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the traditional dust collector is inconvenient to repair, so a bag dust collector which is easy to repair is provided, which uses a step ladder combined with a spiral ladder to facilitate operators to climb.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A bag dust collector that is easy to maintain, comprising a dust collector body, a spiral ladder suspended outside the dust collector body, and the spiral ladder fixedly connected to the dust collector body;

[0006] A step ladder is provided below the spiral staircase, and the top of the step ladder extends to the spiral staircase and is detachably connected to the spiral staircase.

[0007] Preferably, a guardrail is provided on the spiral staircase.

[0008] Preferably, guardrails are provided on both the step ladder and the spiral ladder.

[0009] Preferably, the step ladder is arranged in a straight line.

[0010] Preferably, the top end axle pin of the step ladder is hinged with a support rod, and a locking pin is provided at the hinge.

[0011] Preferably, the support rod includes a first telescopic rod, a second telescopic rod and a third telescopic rod, one end of the first telescopic rod is coupled to the second telescopic rod, one end of the second telescopic rod is coupled to the third telescopic rod, and one end of the third telescopic rod is hinged to the step ladder shaft pin;

[0012] The first telescopic rod has one end opposite to the second telescopic rod and one end opposite to the third telescopic rod, both of which have external threads. Both ends of the second telescopic rod and one end of the third telescopic rod opposite to the second telescopic rod have internal threads.

[0013] The beneficial effect of the utility model is that when the lower part of the dust collector body needs to be repaired, only the step ladder is needed; when the higher part of the dust collector body needs to be repaired, the operator climbs up to the spiral staircase through the step ladder, and then stands on the spiral staircase to repair the dust collector body, and the operation is also relatively convenient and simple.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0020] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned direction words are not used to limit the present invention.

[0021] according to Figure 1-3 As shown, a bag dust collector that is easy to maintain includes a dust collector body 1, with a spiral ladder 2 suspended from the dust collector body 1 and fixedly connected to the dust collector body 1; a step ladder 3 is provided below the spiral ladder 2, the top of which extends to the spiral ladder 2 and is detachably connected to the spiral ladder 2. When the lower part of the dust collector body 1 needs to be repaired, only the step ladder 3 is used. When the higher part of the dust collector body 1 needs to be repaired, the operator climbs up the spiral ladder 2 via the step ladder 3, and then stands on the spiral ladder 2 to repair the dust collector body 1, which is relatively convenient and simple to operate.

[0022] according to Figure 1-3As shown, guardrails 4 are provided on both the step ladder 3 and the spiral staircase 2, or guardrails 4 are provided only on the spiral staircase 2. The step ladder 3 is arranged in a straight line. The top axis pin of the step ladder 3 is hinged with a support rod 6, and a locking pin 5 is provided at the hinge. The support rod 6 includes a first telescopic rod 61, a second telescopic rod 62 and a third telescopic rod 63, one end of the first telescopic rod 61 is coupled to the second telescopic rod 62, one end of the second telescopic rod 62 is coupled to the third telescopic rod 63, and one end of the third telescopic rod 63 is hinged to the axis pin of the step ladder 3; one end of the first telescopic rod 61 relative to the second telescopic rod 62 and one end of the second telescopic rod 62 relative to the third telescopic rod 63 are both provided with external threads, and both ends of the second telescopic rod 62 and one end of the third telescopic rod 63 relative to the second telescopic rod 62 are both provided with internal threads.

[0023] Combine Figure 1-3 As shown, when the step ladder 3 is used alone, the support rod 6 arranged at the top of the step ladder 3 plays a supporting role. The free end of the support rod 6 is used to abut against the dust collector body 1, so that there is a gap between the top of the step ladder 3 and the dust collector body 1, which is convenient for the operator to climb higher. The length of the support rod 6 is adjustable and is used to make appropriate adjustments for different maintenance functions. The locking pin 5 is set to lock the support rod 6 when the support rod 6 is propped up to prevent the support rod 6 from being reset due to external force. In addition, a non-slip rubber sleeve is provided at the bottom of the step ladder 3 to prevent the operator from slipping when climbing the step ladder 3.
