DETAILED DESCRIPTION
[0024] The utility model will be further elaborated in the following with the drawings and examples.
[0025] As Figures 1-2 The utility model discloses a high temperature resistant low emission filter cartridge, including lower cover body 4, the fixed setting of a plurality of support rods 10 along the annular of lower cover body 4, wherein filter core 1 is set on the periphery of support rod 10, and the support of its inside is realized by means of support rod 10. The periphery of filter core 1 is fastened by tightening belt 14, and tightening belt 14 is axially spaced distribution.
[0026] The outer edge of lower cover body 4 is formed with baffle ring 5 upwards, and baffle ring 5 further tightly binds the bottom periphery of filter core 1.
[0027] The upper side of filter core 1 is provided with upper cover body 2 for pressing and connecting to mounting plate 12, wherein the inner ring of lower cover body 4 is fixedly installed with two long rods 3 opposite, long rod 3 extends and penetrates the through -hole 8 of the corresponding opening of upper cover body 2, and the upper end of long rod 3 is provided with screw thread 7, and the position of upper cover body 2 is pressed and limited by external bolt 9, and lower cover body 4 forms an integrated wrapping filter core 1.
[0028] Considering that the exhaust gas is easy to not filter through the circumferential filter core 1 and directly leak from the upper side and the junction of upper cover body 2, which greatly affects the exhaust gas filtration efficiency.
[0029] As shown in the drawing, Figure 3 The lower side of upper cover body 2 is provided with annular slot 11, which wraps the upper side of filter core 1 and is attached to the upper end surface, and the peripheral sidewall of the bottom of upper cover body 2 at slot 11 is attached to filter core 1, further preventing exhaust gas from passing through the gap between upper cover body 2 and filter core 1, and enhancing the sealing of filtration. Of course, for some disposable filter core 1, it can also be coated with glue to achieve more efficient sealing.
[0030] For the convenience of external assembly of the whole filter cartridge, upper cover body 2 is further improved, specifically, referring to the drawing, Figure 4As shown, the circumferential outer edge of the upper cover body 2 is integrally formed with an extension 6 (specifically, a ring-shaped outward protrusion), and an inlet clamping groove 61 is formed at the same direction rotation position (such as counterclockwise or clockwise) of the extension 6. The inlet clamping groove 61 forms a slot with a certain entering length, and an accommodation groove 62 is formed at the inner side position.
[0031] Correspondingly, a clamping column 13 corresponding to the number of extensions 6 is fixed on the corresponding outer mounting plate 12. All clamping columns 13 are located at the rotation position of the extension 6, so that the clamping column 13 can be clamped into the extension 6 one by one.
[0032] It should be noted that the entering width of the inlet clamping groove 61 is always consistent, and the radial length of the accommodation groove 62 is greater than the width of the inlet clamping groove 61.
[0033] As shown in the accompanying drawings Figure 5 As shown, the extension 6 adopts a fixed column 131 fixed to the mounting plate 12. The upper end of the fixed column 131 is connected with an elastic column 133 having a deformation ability. The size of the elastic column 133 is greater than the width of the inlet clamping groove 61, and is adapted to the radial size of the accommodation groove 62. After the filter cartridge is rotated by force, the elastic column 133 can be clamped into the accommodation groove 62, and is restored to be clamped in the accommodation groove 62 through the elastic column 133, so that the upper cover body 2 is limited on the mounting plate 12.
[0034] The fixed column 131 does not contact (is located below) the inlet clamping groove 61. For example, the fixed column 131 can be embedded in the mounting plate 12, or the size of the fixed column 131 can be reduced to be able to rotate into the inlet clamping groove 61.
[0035] The circumferential direction of the elastic column 133 is provided with a plurality of deformation grooves 132. The deformation grooves 132 are long strips and are arranged in the axial direction of the elastic column 133, so that the elastic column 133 is more conducive to deformation. The elastic column 133 can adopt a material that can be deformed and reset, such as a memory metal alloy, a shape memory plastic (SMP), a heat resilient plastic (HPE), and the like.
[0036] The mounting plate 12 described above is specifically a dust collector inner connecting part structure. The present scheme does not improve the dust collector, so it is not described. Only the mounting plate 12 with a connection relationship is shown. When used, the filter cartridge can be placed from top to bottom into the mounting plate 12. The upper cover body 2 is clamped and fastened with the mounting plate 12 by a larger force, so as to realize quick assembly.
[0037] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without deviating from the scope of the present invention. The novel technical scope is not limited to the content in the specification, and the scope of protection must be determined according to the scope of claims.
