Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter cartridges, in particular to a dust removal filter cartridge which is easy to install. Background Art

[0002] The dust filter cartridge is a star-shaped filter cartridge made of a certain length of stiff filter material folded into pleats and glued end to end. There are many types of filter cartridges, which are divided into thin and long and thick and short. The thin and long filter cartridge (such as φ≤160, L=1~2m) has large gaps and large angles between pleats (such as 45 pleats), fewer and shallower pleats, and a filtration area 2~5 times larger than that of a filter bag with the same diameter and length. It is easy to clean and has good effect. It is suitable for filtering dust with a concentration of ≥15g / m3 and a filtration wind speed of 0.6~1.2m / min. The thick and short filter cartridge (such as φ350, L=0.66 m) It has a large diameter, short length, many pleats (120 to 350 pleats) and deep, small gaps between pleats, and a large filtration area, which is 14 to 35 times larger than the filter bag with the same diameter and length. It is suitable for layout in places with small areas and small spaces. However, due to the small pleat angles, dust is easy to accumulate and difficult to clean. It is suitable for filtering and dust removal of dust with a concentration of ≤5g / m3. The filtration wind speed should not be greater than 0.6m / min. The dust removal filter cartridge can greatly increase the effective filtration area, ensure a low and stable pressure difference, and increase the air flow rate. It is particularly suitable for industries with high dust concentrations.

[0003] The inventor discovered the following problems in the prior art during the process of realizing the utility model: the existing dust filter cartridge is not easy to install and disassemble during use, which affects people's operation and is not easy to better meet people's use needs.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1The utility model provides a technical solution: a dust filter cartridge that is easy to install, including an annular sleeve 2 and an annular base 12. The upper end of the annular sleeve 2 is provided with a cylinder 1, the annular sleeve 2 is movably installed in the annular base 12, the side wall of the annular sleeve 2 is provided with a pair of jacks 3, and the annular base 12 is provided with a pair of adjustment mechanisms. The adjustment mechanism includes a cavity 8 installed in the annular base 12, the bottom surface of the cavity 8 is provided with a pair of springs 9, and the upper ends of the pair of springs 9 are connected with a lifting block 7. The upper end of the lifting block 7 is provided with a connecting rod 11, the connecting rod 11 is movably connected to the upper wall surface of the annular base 12 and is provided with a button 10, the side wall surface of the lifting block 7 is provided with a short rod 6, and an insertion rod 4 is movably inserted between the cavity 8 and the side wall surface of the annular base 12, and a strip groove 5 is provided in the insertion rod 4, and the short rod 6 is movably connected in the strip groove 5.

[0016] The present embodiment is further configured such that a pair of insertion rods 4 can be movably inserted into a pair of insertion holes 3. The insertion rods are inserted into the insertion holes and are closely attached to the inner walls of the insertion holes, which can reduce vibration.

[0017] The present embodiment is further configured such that one end of a pair of insertion rods 4 is provided with an inclination angle, which helps the annular sleeve to be flexibly inserted into the annular base.

[0018] In this embodiment, the pair of strip grooves 5 are further configured to have an inclination angle. The inclination angle is used to realize the transmission function, and the movement control of the insertion rod is realized by pressing the button.

[0019] This embodiment is further configured such that a filter layer is provided in the cylinder 1. The filter layer is used to block dust and realize a filtering function.

[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0021] Embodiment: First, the annular sleeve 2 and the cylinder 1 can be flexibly inserted into the annular base 12. At this time, the insertion rod 4 is squeezed to move the insertion rod 4, and the movement of the insertion rod 4 drives the bar groove 5 to move. The movement of the bar groove 5 drives the short rod 6 to move downward, and the short rod 6 moves downward to drive the lifting block 7 to move downward and the spring 9 is compressed. When the annular sleeve 2 is inserted into the annular base 12, the annular sleeve 2 can be rotated to align the insertion hole 3 with the insertion rod 4. At this time, the spring 9 rebounds and resets, and the insertion rod 4 can be moved into the insertion hole 3 to fix the annular sleeve 2. When the annular sleeve 2 is inserted into the annular base 12, the bottom of the annular base 12 has a limit plate to prevent the annular sleeve 2 from being over-inserted into the annular base 12. The lower end of the annular base 12 has a fan for vacuuming, and the input end of the fan is connected with the annular sleeve 2 through the annular base 12. After use, a pair of buttons 10 can be pressed at the same time to drive a pair of connecting rods 11 to move downward. The downward movement of the pair of connecting rods 11 drives the spring 9 to be compressed and the insertion rod 4 to move out of the socket 3, so that the annular sleeve 2 can be disassembled.

[0022] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
