Description

Technical Field

[0001] The invention belongs to the technical field of filtering devices of bag dust collectors, and in particular relates to a combined bag cage. Background Art

[0002] At present, with the increasing requirements of the state on dust emission in the environmental protection industry, dust collectors in many industries need to be renovated and added. At the same time, the location and size of many dust collectors are limited, so they can only be moved to high altitudes. It is proposed that the length of the filter device should be more than 8 meters or longer. The general bag cage is designed to be within 8 meters in length for the convenience of transportation and installation. For bag cages longer than 8 meters, many problems arise in production, transportation, installation and maintenance, and the ideal design requirements cannot be met. It is difficult to ensure the verticality of the center after production and installation. The transportation packaging volume is large and the cost is high. Due to the limitation of the bag cage length, it is necessary to design a high rain shelter on the top of the dust collector, which is costly. The bag cage installation and maintenance are inconvenient. Summary of the invention

[0003] The purpose of the present invention is to provide a combined bag cage to solve the problems of failure to ensure verticality in the production of long bag cages, high transportation costs, and inconvenient installation and maintenance.

[0008] It is further preferred that the vertical support rods and the transverse support rings are both made of stainless steel, and the vertical support rods are uniformly welded to the outer sides of the transverse support rings.

[0009] It is further preferred that the telescopic spring bag cage is bent into a spiral shape by a stainless steel rod, and the telescopic spring bag cage can be compressed and stretched, and the two ends of the telescopic spring bag cage are respectively welded and fixed to a detachable concave pipe and a detachable convex pipe.

[0010] It is further preferred that the detachable connecting pipe is provided with a supporting groove 1 and a supporting groove 2, the end of the vertical support rod is welded to the side wall of the supporting groove 1, and the end of the telescopic spring bag cage is welded to the bottom of the supporting groove 2.

DETAILED DESCRIPTION

[0021] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 to Figure 2 The combined bag cage shown in the figure comprises at least two bag cage monomers 2, such as Figure 1 A structure of three-section bag cage monomers 2 is used, and a detachable and retractable spring bag cage 7 is connected between two adjacent bag cage monomers 2. A connecting pipe 1 is fixed to the top of one of the bag cage monomers 2, and a chassis 8 is fixed to the bottom of one of the bag cage monomers 2.

[0023] When in use, first put the dust removal bag on the outside of the bottom of the bag cage monomer containing the chassis. During the process of installing the bag, the bag cage is lengthened section by section while the bag is installed. The bag cage monomer and the retractable spring bag cage are alternately and detachably connected, and installed upward to the upper mouth of the bag, and then tied to the outside of the lower part of the connecting pipe.

[0024] The upper part of the topmost bag cage monomer and the lower part of the bottommost bag cage monomer have a diameter change in the form of a contraction opening, mainly for the convenience of installation, especially the final contraction of the bottom to enable smooth installation. Considering the unified structure, the same structure is used in the middle.

[0025] For quick connection, the bag cage unit 2 is connected to the retractable spring bag cage 7 via a detachable connecting pipe, which includes a detachable convex pipe 4 and a detachable concave pipe 5. Figure 2 As shown, the detachable male pipe 4 and the detachable female pipe 5 are snap-connected and coaxial.

[0026] In order to facilitate the installation of dust removal bags, the bag cage monomers 2 are circular and have the same diameter. Each bag cage monomer 2 is fixedly connected vertically and horizontally by a plurality of vertical support rods 3 and at least two transverse support rings 6, and the transverse support rings 6 are circular.

[0027] The vertical support rods 3 and the transverse support rings 6 are both made of stainless steel, and the vertical support rods 3 are uniformly welded to the outer sides of the transverse support rings 6 .

[0028] The telescopic spring bag cage 7 is formed by bending a stainless steel rod into a spiral shape, and the telescopic spring bag cage 7 can be compressed and stretched. The two ends of the telescopic spring bag cage 7 are respectively welded and fixed to the detachable concave pipe 5 and the detachable convex pipe 4.

[0029] In order to make the connection more stable, a support groove 1 9 and a support groove 2 10 are provided on the detachable connecting pipe, the end of the vertical support rod 3 is welded to the side wall of the support groove 1 9, and the end of the retractable spring bag cage 7 is welded to the bottom of the support groove 2 10.

[0030] like Figure 3-6 As shown, the detachable convex tube 4 is provided with a protruding clamping tube 14, and a plurality of clamping blocks 13 are provided on the top of the clamping tube 14. The detachable concave tube 5 is provided with a concave clamping tube 2 11 that cooperates with the clamping tube 14, and a plurality of clamping grooves 12 that cooperate with the clamping blocks 13 are provided on the inner wall of the clamping tube 2 11 along the axial direction.

[0031] In terms of transportation, conventional bag cages are fixed and have no telescopic springs. They occupy a large transportation volume during transportation, resulting in high transportation costs. However, this structure adopts a telescopic spring structure. For bag cages of the same length and number, the transportation volume can be reduced by more than half, and the transportation cost is also reduced. Therefore, it is energy-saving and cost-reducing overall.

[0032] In terms of installation, conventional bag cages are fixed, and a relatively large crane is required to lift the bag cage onto the equipment during installation. However, this structure adopts a telescopic spring structure, and a small crane can be used to lift the bag cage onto the equipment during lifting, so overall it saves energy and reduces costs.

[0033] In terms of maintenance, conventional bag cages are fixed and require several people to install, which is particularly inconvenient and laborious. However, this structure adopts a segmented plug-in structure, which is very convenient to install, so it is generally practical and cost-effective.

[0034] In summary, the present invention can reduce the difficulty of bag cage production and better ensure the coaxiality of the bag cage by setting it as a monomer combination structure. In addition, the bag cage monomers are connected by a retractable spring bag cage, and the length of the retractable bag cage can be stretched and compressed as needed, which is suitable for various length requirements and is more convenient to transport and install. The retractable spring bag cage is combined with the bag cage monomer to achieve the bag cage's self-adaptive verticality by relying on gravity.

[0035] In the description of the present invention, the terms "inside", "outside", "longitudinal", "lateral", "upper", "lower", "top", "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.
