Description

Technical Field

[0001] The utility model belongs to the technical field of air box bag dust collectors, in particular to an air box bag dust collector which is convenient for replacing filter bags. Background Art

[0002] The air box bag dust collector is a widely used separation equipment, which is widely used in food, chemical industry, construction engineering and other fields. Dust removal has always been an important part of environmental governance. Dust removal devices are needed in various fields for dust removal. Dust removal devices also have various structural types.

[0003] In the prior art, during the operation of the pulse dust collector, the filter bags need to be cleaned and replaced regularly. However, when the filter bags are actually replaced in the pulse dust collector, the traditional structure adopted by the current pulse dust collectors can meet the needs of operation and replacement, but the replacement efficiency is low, and the replacement operation is difficult and labor-intensive.

[0004] The Chinese patent with the authorization announcement number CN114053793B discloses a vertical pulse back-blowing explosion-proof dust collector, including a purification chamber, a bearing keel, an adjustment mechanism, a dust bag frame, a protective cover, a negative pressure fan, a guide pipe, a shunt pipe, a flexible drainage pipe, a connecting pipe head and a driving circuit; the purification chamber is symmetrically distributed on both sides of the center line of the bearing keel and is covered outside the bearing keel, the dust bag frame is respectively embedded in the two purification chambers, the dust bag frame is connected to the connecting pipe head, and the connecting pipe head is connected to the shunt pipe through a flexible drainage pipe. Its use method includes three steps: system assembly, overall replacement of filter bags, and precise replacement of filter bags, so as to improve the integration and modularization of bag dust collector equipment, improve the efficiency and continuity of dust removal operations; improve the efficiency of filter bag installation, positioning and replacement operations, and use the elastic deformation capacity of filter bags to effectively improve the efficiency of dust and other pollutants in the filter bags.

[0005] However, the above patent uses electromagnets to fix the filter bags. Although it can achieve a good fixing effect and facilitate replacement, the use of electromagnets increases the cost of the equipment, which is not worth the cost just for the convenience of replacing the filter bags. In addition, during long-term use, the electromagnets are prone to failure due to many reasons such as line aging or mechanical vibration of the equipment, which only increases the maintenance time and cost of the equipment and is not conducive to actual use.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0026] refer to Figure 1-6, an air box bag dust collector which is easy to replace filter bags, comprises a box body 10, a perforated plate 26 is fixedly connected inside the box body 10, a plurality of through holes are evenly distributed on the perforated plate 26, a dust filter bag bracket 30 is inserted into each through hole on the perforated plate 26, a dust filter bag 25 is sleeved on the outer side of each dust filter bag bracket 30, a lock buckle 29 for locking the dust filter bag 25 on the perforated plate 26 is provided at each through hole on the perforated plate 26, a mounting ring 32 is fixedly connected to the top of each dust filter bag bracket 30, the diameter of each mounting ring 32 is larger than the diameter of the through hole on the perforated plate 26, and the top annular edge of each dust filter bag 25 is fixedly connected to the corresponding mounting ring 32.

[0027] A dust bag holder 30 corresponding to the diameter of the through hole on the perforated plate 26 is used to replace the problem of interference fit between the traditional filter bag and the perforated plate 26, which is inconvenient to install and replace. The filter bag is initially fixed to the perforated plate 26 using a mounting ring 32 to prevent it from falling during installation or replacement.

[0028] For further reference, Figure 4-6 The bottom of each lock buckle 29 is provided with a conical end 33 for locking the dust filter bag 25 on the perforated plate 26. The maximum diameter of the conical end 33 is larger than the diameter of the through hole on the perforated plate 26. The lock buckle 29 is made of elastic metal material. A plurality of slots 34 for avoiding the rod-shaped structure of the dust filter bag bracket 30 are evenly distributed at the conical end 33. The portion of the lock buckle 29 located on the upper side of the perforated plate 26 completely wraps the mounting ring 32.

[0029] The dust filter bag 25 is propped up and firmly buckled on the perforated plate 26 by the tapered end 33, and the locking buckle 29 wraps and fixes the mounting ring 32, so that the filter bag is simply, stably and firmly fixed on the perforated plate 26, and the sealing of the contact between the perforated plate 26 and the dust filter bag 25 is effectively improved, and the filtering effect is improved. The shape of the tapered end 33 can automatically shrink during plug-in installation to facilitate installation and increase the installation speed. The locking buckle 29 has a low production cost, a simple and stable structure, and a good fixing effect, and is suitable for wide promotion and use.

[0030] For further reference, Figure 4 A pull rope 31 is fixedly connected to the end of each lock buckle 29 at the conical end 33, and a pull ring 28 is fixedly connected to the upper end of each pull rope 31.

[0031] When the lock buckle 29 needs to be removed to replace the dust filter bag 25 , the lock buckle 29 can be simply and conveniently removed by pulling the pull rope 31 to shrink the tapered end 33 , thereby facilitating replacement work and improving the efficiency of replacing the dust filter bag 25 .

[0032] In this embodiment, during installation, the dust filter bag 25, the dust filter bag bracket 30 and the mounting ring 32 are first inserted into the through hole on the perforated plate 26 until the mounting ring 32 is hung on the edge of the through hole of the perforated plate 26 and no longer falls. Then, the lock buckle 29 is inserted from the center of the mounting ring 32. Since the lock buckle 29 is made of elastic metal, when the operator presses down the lock buckle 29, the tapered end 33 is restricted by the mounting ring 32 and shrinks inward, so that the diameter at the tapered end 33 is reduced to facilitate entry.

[0033] Subsequently, when the conical end 33 passes through the mounting ring 32, the conical end 33 unfolds again under the elasticity of the lock buckle 29 itself, and props up the dust filter bag 25 and firmly buckles it on the perforated plate 26. At the same time, the lock buckle 29 wraps and fixes the mounting ring 32, so that the filter bag is simply, stably and firmly fixed on the perforated plate 26, and the sealing of the contact between the perforated plate 26 and the dust filter bag 25 is effectively improved, thereby improving the filtering effect.

[0034] When replacing the dust filter bag 25, the lock buckle 29 can be simply and conveniently removed by pulling the pull rope 31 to shrink the tapered end 33, thereby facilitating replacement.

[0035] Moreover, the fixing method is simple and efficient, low in cost, low in failure rate, easy to maintain and suitable for wide promotion.

[0036] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0037] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0038] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field.
