Description

Technical Field

[0001] The utility model belongs to the technical field of bag dust collectors, in particular to a dust filter bag component of a bag dust collector. Background Art

[0002] The air box bag dust collector is a widely used separation equipment, widely used in food, chemical, 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, but the most important component is the filter bag for filtering dust. When dust removal is performed, the filter bag filters the dust entering the dust collector. When too much dust is attached to the filter bag, the jet device on the dust collector blows air into the filter bag to expand the filter bag and blow off the attached dust to ensure the dust removal and filtration efficiency of the filter bag. However, this traditional cleaning method is not effective. After long-term use, the filtration efficiency of the filter bag will still decrease.

[0003] The Chinese patent with the authorization announcement number CN115970403B discloses a high-efficiency pulse dust collector. When cleaning the dust attached to the surface of the filter bag, the pulse generator sprays compressed air to expand the filter bag and vibrate to remove some sticky dust attached to the filter bag. After the pulse cleaning is completed, the output end of the first hydraulic cylinder moves back and forth, driving the rack to slide back and forth, and the rack drives all the gears to rotate back and forth. The rotation of the gear drives the positioning ring to rotate back and forth, and the soft paddle contacts the surface of the filter bag to vibrate the surface of the filter bag; at the same time, the output end of the second hydraulic cylinder moves back and forth, driving the positioning plate to move back and forth along the height direction of the lower box body. When the positioning plate moves up and down, the sticky dust particles attached to the inner wall of the lower box body can be scraped off; the soft paddle vibrates the filter bag in the circumferential and longitudinal directions, accelerating the separation of sticky dust particles on the surface of the filter bag from the filter bag, and ensuring the dust removal efficiency of the pulse dust collector.

[0004] However, compared with the traditional dust collector, the above patent adds many cleaning structures for the filter bags, which increases the production and use costs of the equipment, and this cleaning method is difficult to modify on the basis of the existing traditional dust collector, which is not conducive to popularization of production and use. While adding the cleaning structure, the failure rate of the dust collector will also increase, thereby increasing the maintenance time and maintenance cost of the equipment. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model solves the technical problem of effectively increasing the surface area of ​​the dust filter bag without changing the occupied volume by arranging a star-shaped dust filter bag, thereby improving the filtering efficiency; and when the dust filter bag is cleaned by a paint spraying device, the star-shaped dust filter bag has a better expansion effect and a better vibration dust removal effect, which can effectively improve the cleaning effect to ensure the filtering efficiency of the dust filter bag and increase its service life.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0007] A dust filter bag component of a bag dust collector comprises a shaft rod, on which a plurality of brackets are evenly distributed and fixedly connected, each leg of the bracket is fixedly connected to a support rod, and a dust filter bag with a star-shaped cross section is sleeved on the outer side of the support rod.

[0008] By setting a star-shaped dust filter bag, the surface area of ​​the dust filter bag can be effectively increased without changing the occupied volume, thereby improving the filtration efficiency; and when the dust filter bag is cleaned by the paint spraying device, the star-shaped dust filter bag has a better expansion effect and a better vibration dust removal effect, which can effectively improve the cleaning effect to ensure the filtration efficiency of the dust filter bag and increase its service life.

[0009] Furthermore, a disc-shaped bottom plate is fixedly connected to the bottom end of the support rod.

[0010] Furthermore, an annular top ring is fixedly connected to the top end of the support rod, the upper and lower ends of the dust filter bag are fixedly connected to the top ring and the bottom plate respectively, and the shaft rod is fixedly connected to the bottom plate.

[0011] By providing the top ring and the bottom plate, the dust filter bag can be effectively fixed to improve the overall structural strength.

[0012] Furthermore, a plurality of elastic ropes are evenly distributed and fixedly connected between the top ring and the bottom plate in a circumferential direction.

[0013] Furthermore, each of the elastic ropes is located on the outside of the dust filter bag, and each of the elastic ropes is located at a recessed portion of the dust filter bag toward the inside.

[0014] By setting up elastic ropes, after the dust collector uses jets to clean the dust bag and make the dust bag expand, the elasticity of the elastic ropes is used to restore the dust bag to its original star-shaped state, thereby maintaining the original working efficiency and working state of the dust bag, avoiding repeated maintenance by personnel and increasing its service life.

[0015] In summary, compared with the prior art, the beneficial effects of the present invention are:

[0022] 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.

[0023] refer to Figure 1-4 A dust filter bag component of a bag dust collector includes a shaft rod 38, on which a plurality of brackets 40 are evenly distributed and fixedly connected, each leg of the bracket 40 is fixedly connected to a support rod 39, and a dust filter bag 25 with a star-shaped cross-section is sleeved on the outer side of the support rod 39.

[0024] By providing a star-shaped dust filter bag 25, the surface area of ​​the dust filter bag 25 can be effectively increased without changing the occupied volume, thereby improving the filtering efficiency; and when the dust filter bag 25 is cleaned by the paint spraying device, the star-shaped dust filter bag 25 has a better expansion effect and a better vibration dust removal effect, which can effectively improve the cleaning effect to ensure the filtering efficiency of the dust filter bag 25 and increase its service life.

[0025] For further reference, Figure 1-2 The bottom end of the support rod 39 is fixedly connected to a disc-shaped bottom plate 36, the top end of the support rod 39 is fixedly connected to an annular top ring 35, the upper and lower ends of the dust filter bag 25 are fixedly connected to the top ring 35 and the bottom plate 36 respectively, and the shaft rod 38 is fixedly connected to the bottom plate 36.

[0026] By providing the top ring 35 and the bottom plate 36 , the dust filter bag 25 can be effectively fixed to improve the overall structural strength.

[0027] For further reference, Figure 3 A plurality of elastic ropes 37 are evenly distributed and fixedly connected between the top ring 35 and the bottom plate 36 in the circumferential direction. Each elastic rope 37 is located outside the dust filter bag 25 , and each elastic rope 37 is located at a concave portion inside the dust filter bag 25 .

[0028] By providing the elastic rope 37, after the dust collector performs jet cleaning on the dust filter bag 25 to expand the dust filter bag 25, the elasticity of the elastic rope 37 is utilized to restore the dust filter bag 25 to its original star-shaped state, thereby maintaining the original working efficiency and working state of the dust filter bag 25, avoiding repeated maintenance by personnel and increasing the service life.

[0029] In this embodiment, when in use, the user can directly use this patent on the existing dust collector to replace the traditional cylindrical filter bag. When the dust collector is working, the star-shaped dust filter bag 25 uses a larger surface area than the traditional cylindrical filter bag of the same volume, so that the dust can be filtered more efficiently, greatly improving the filtering effect.

[0030] After using the present invention for a long time, a large amount of dust will adhere to the surface of the dust filter bag 25, affecting the filtering efficiency of the dust filter bag 25. At this time, the jet device on the original dust collector is operated to spray high-pressure air into the dust filter bag 25, and the dust filter bag 25 will expand outward. Due to the star-shaped setting of the dust filter bag 25, its expansion effect is better, making the effect of expansion and shaking off dust better, thereby improving the cleaning effect of the dust filter bag 25 and further improving the filtering efficiency of the dust filter bag 25.

[0031] While the dust filter bag 25 expands, the elastic rope 37 is also squeezed and deformed outward. After the dust filter bag 25 expands, when air is no longer injected into the dust filter bag 25, the dust filter bag 25 will be gathered inward again under the elasticity of the elastic rope 37. In the process of the dust filter bag 25 gathering, due to the support of the support rod 39, the dust filter bag 25 returns to the star-shaped state and continues to maintain the original working efficiency and work stably, avoiding the dust filter bag 25 from being unable to recover after expansion, thereby reducing the cost and time of manual maintenance.

[0032] Moreover, the use of this patent does not require modification of the original dust collector, and can effectively improve the filtering effect, and avoid problems such as unstable equipment operation caused by modified equipment.

[0033] 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.

[0034] 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.

[0035] 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. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the present application, and should be within the scope of protection of the claims attached to the present application.
