Description

Technical Field

[0001] The invention relates to the field of dust removal filter bags, and in particular to a graphene dust removal filter bag that is easy to disassemble and replace and a dust removal method thereof. Background Art

[0002] Graphene dust filter bags, as an important component in modern industrial dust removal equipment, are mainly composed of graphite fiber and glass fiber (or other reinforcing fibers). The addition of graphite fiber not only improves the conductivity of the filter bag, but also enhances its high temperature resistance, corrosion resistance and other characteristics. At the same time, reinforcing fibers such as glass fiber give the filter bag good mechanical strength and stability. The graphene dust filter bag adopts a multi-layer composite structure, and graphite fiber and glass fiber and other materials are tightly combined through a special process. This structure enables the filter bag to have high filtration efficiency and low resistance while maintaining excellent performance.

[0003] The outer wall needs to be replaced after a period of use. The bag body and cage frame are an integrated structure and need to be replaced as a whole. The replacement process requires cumbersome disassembly and assembly steps. At the same time, as a consumable for dust removal, the overall replacement cost is relatively high.

[0038] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0039] like Figure 1-6 As shown, the present invention proposes a graphene dust filter bag that is easy to disassemble and replace, comprising a bag body 1, the opening end of the bag body 1 is formed with a bag opening clamp ring 11 with a single-side protrusion, and a support ring 12 is installed at the bottom;

[0040] The upper opening of the bag body 1 is stretched into a ring shape by the annular bag opening clamp ring 11, and the lower part is supported by the support ring 12 to achieve support for the upper and lower parts, so that the upper and lower parts of the bag body 1 are always in an open state;

[0041] The clamping mechanism includes an outer ring frame 21 sleeved on the outer periphery of the bag mouth clamp ring 11, a gasket 22 is placed in the clamping gap between the two, and a raised first combined ring plate 23 is also installed on the top of the outer ring frame 21;

[0042] The cage mechanism includes a flower plate frame 31 arranged above the outer ring frame 21, and a second combination ring plate 32 matched with the gasket 22 is formed on the flower plate frame 31, and a cage frame ring 33 is clamped in the second combination ring plate 32, and cage frame rods 34 are formed in an array on the cage frame ring 33;

[0043] The inner support mechanism includes a support plate 51 installed at intervals on each cage frame ring 33, a cylinder 52 is installed on the support plate 51, a movable piston rod 53 is installed at the output end of the cylinder 52, and the other end of the piston rod 53 is connected to a shaft frame 54, a shaft rod 55 passes through the middle of the shaft frame 54, and a pulley 56 is installed on the shaft rod 55;

[0044] The lifting mechanism includes a rod seat 61 arranged on the outside of the bag body 1, on which a guide rod 62 and a screw 63 are installed. The screw 63 is connected to the output end of the screw motor 64, and the outer wall is sleeved with a screw slide 65 sliding along the guide rod 62. The screw slide 65 is connected to the outer ring frame 21 through a clamp 66.

[0045] It should be noted that the filter bag is improved into a split structure, and the bag body 1 and the cage mechanism are fixed by a clamping mechanism. When replacing, only the bag body 1 needs to be replaced. On the one hand, the tedious steps of installation at the flower plate mouth are eliminated, and on the other hand, the problem of high consumables cost in overall replacement is solved.

[0046] In this embodiment, when the bag body 1 is installed, the bag mouth clamp ring 11 on the upper part of the bag body 1 is installed on the outer ring frame 21, and the raised part of the bag mouth clamp ring 11 is embedded in the inner part of the outer ring frame 21 to pre-fix the upper part of the bag body 1. Because the outer ring frame 21 cooperates with the lifting mechanism, the screw motor 64 drives the screw 63 at the output end to rotate, and the screw slide 65 is controlled by the spiral of the screw 63 to make an up and down linear displacement along the guide rod 62. The outer ring frame 21 connected by the clamping member 66 drives the bag body 1 to make a synchronous displacement, which plays a role in guiding the bag body 1 upward, until the flower plate frame 31 and the outer ring frame 21 are plugged and fixed by the second combined ring plate 32 and the first combined ring plate 23, and the installation of the bag body 1 is completed;

[0047] The cage frame mechanism includes a cage frame ring 33 and a cage frame rod 34 which are stacked. Although the cage frame ring 33 is not in direct contact with the bag body 1, the bottom of the cage frame rod 34 penetrates into the slot of the support ring 12. Since the upper part of the support ring 12 is a slotted structure and the outer wall is attached to the inner wall of the bag body 1, on the one hand, the cage frame rod 34 is limited to achieve contact between the cage frame rod 34 and the bag body 1, and on the other hand, the support ring 12 can prevent the cage frame rod 34 from piercing the bag body 1.

[0048] The setting of the internal support mechanism can expand the middle section of the bag body 1 internally, and the cylinder 52 drives the piston rod 53 to extend, driving the shaft frame 53, the shaft rod 55 and the pulley 56 to move toward the inner wall of the bag body 1 until the pulley 56 is attached to the bag body 1, thereby providing internal support to the middle section of the bag body 1 at equal angles, thereby indirectly achieving the coordination between the bag body 1 and the cage frame ring 33.

[0049] like Figure 3 As shown, a "ring-shaped" cavity is reserved between the second combined ring plate 32 and the first combined ring plate 23, and the sealing mechanism includes an airbag component 41 arranged between the second combined ring plate 32 and the gasket 22. The airbag component 41 is a deformable component with a built-in inflatable cavity, and a vent valve 42 is installed inside that passes through the upper part of the flower plate frame 31. The upper and lower parts of the airbag component 41 are also provided with sealing gaskets 43 attached to the outer ring frame 21 and the flower plate frame 31.

[0050] As an example of sealing during installation of the bag body 1: in order to prevent dust-containing gas from penetrating through the combination of the clamping mechanism and the sealing mechanism and causing the dust-containing gas to be discharged, after the bag body 1 is installed, air is inflated into the airbag component 41 through the vent valve 42. Since the airbag component 41 is a deformable component, it inflates and expands outward, pushing the sealing gasket 43 to a position that is tightly attached to the outer ring frame 21 and the flower plate frame 31, thereby sealing the gap at the connection and ensuring the sealing of the connection.

[0051] As an example of disassembly of a graphene dust filter bag: since the bag body 1 eliminates the traditional bolt structure as a connecting part, its support during installation is achieved through an external lifting mechanism. Therefore, when disassembling, the outer ring frame 21 connected to the clamping part 66 is moved downward by sliding the screw slide 65 in the lifting mechanism, thereby separating the outer ring frame 21 from the flower plate frame 31, and the bag body 1 is removed from the ring plate frame 31, and the bag body 1 can be replaced.

[0052] When disassembling, the inner support mechanism needs to be reset to the initial position, that is, the pulley 56 has no contact with the inner wall of the bag body 1, so as to prevent the pulley 56 from scratching the vertically movable bag body 1.

[0053] It should be added that: the inner layer of the bag body 1 is made of graphene material; due to the addition of graphite fiber, the graphene dust filter bag also has good conductive properties. This feature makes the filter bag have unique application advantages in occasions such as electrostatic dust removal. After being powered on and heated, it has adsorption properties, which can dry and adsorb wet dust, and increase the drying and separation effects during the transmission of dust-containing gas.

[0054] In order to facilitate the cleaning of the bag body 1 after it becomes dirty, further, a purge mechanism is provided inside or outside the bag body 1, and the purge mechanism cleans the dust attached to the bag body 1 by supplying air.

[0055] like Figure 1 and Figure 6 As shown, the rotating mechanism includes a rotating disk 72 arranged below the bag body 1. The rotating disk 72 is controlled to rotate by the driving device 71. The inner cavity of the rotating disk 72 is provided with a clamping groove. The rotating disk 72 and the support ring 12 are respectively attached to the outer wall and the inner wall of the bag body 1.

[0056] In one embodiment, when the bag body 1 is purged, the rotating mechanism can be used, and the driving device 71 drives the rotating disk 72 to rotate, thereby driving the bag body 1 to rotate. At this time, the bag mouth clamp ring 11 rotates along the inside of the outer ring frame 21. At the same time, the internal cage frame rod 34 can rotate along the slot of the support ring 12, playing the role of orbital circular guide. At the same time, because the contact position between the internal support mechanism and the bag body 1 is designed as a pulley 56, the pulley 56 can rotate in a circle along the shaft 55, and the end face attached to the inner wall of the bag mouth clamp ring 11 is a smooth curved surface structure. When the bag body 1 rotates, its contact with the smooth curved surface of the pulley 56 causes less damage to the bag body 1, so that the bag body 1 can be rotated 360° and evenly receive gas blowing, thereby improving the surface cleaning effect of the bag body 1.

[0057] A dust removal method comprises the following steps:

[0058] Step 1: Install the cage mechanism at the opening of the flower plate, install the bag body 1 at the clamping mechanism through the bag opening clamp ring 11, lift the bag body 1 upward through the lifting mechanism, and install it in combination with the cage mechanism at the opening of the flower plate to establish a dust filtering channel;

[0059] Step 2: During dust removal, the bag body 1 is electrified. The graphene material has conductive properties and has adsorption properties after being electrified and heated, and can dry and adsorb the dust with humidity;

[0060] Step 3: After the dust removal is completed, the bag body 1 is powered off, and the surface of the bag body 1 is purged by the purging mechanism;

[0061] Step 4: The bag body 1 is driven to rotate by the rotating mechanism to sweep the surface at all angles.

[0062] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
