the utility model provides a mounting structure of filter core, its characterized in that, including setting up in the filter and be used for separating solid particle's sedimentation tube and setting up just be used for secondary separation's filter core on the sedimentation tube, be provided with the air inlet that supplies the gaseous entering of taking solid impurity and with pure gas outlet on the filter respectively.

In a preferred embodiment of the utility model, a centering assembly is also included, disposed within the filter and ensuring the tightness of the filter cartridge.

In a preferred embodiment of the utility model, the centering assembly comprises a centering frame which is arranged on the filter element and can ensure that the center line of the filter element is parallel to the center line of the filter, a centering disc which is arranged on the filter element and can ensure that the upper end surface and the lower end surface of the filter element are sealed, and a pull rod which is connected with the centering frame and the centering disc.

In a preferred embodiment of the utility model, the tie rod is connected to the centering frame and centering disc by a bolt assembly.

In a preferred embodiment of the utility model, the interior of the settling tube is of a hollow structure.

In a preferred embodiment of the utility model, the sides of the settling tube are connected to the filter by a mounting plate.

In a preferred embodiment of the utility model, the bottom of the filter cartridge is connected to the settling tube by a bottom plate.

Due to the adoption of the technical scheme, the utility model has the beneficial effects that: according to the utility model, solid particles can be separated before materials enter the filter element, in the process of passing through the sedimentation pipe, bigger solid particles fall down and are separated in the process, the materials enter the filter element, and the purer gas is discharged from the upper part through secondary separation of the filter element.

Detailed Description

The utility model is further described below in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the implementation of the utility model easy to understand.

Referring to fig. 1 to 3, a filter cartridge mounting structure includes a settling tube 10 provided in a filter 1 for separating solid particles and a cartridge 20 provided on the settling tube 10 for secondary separation, and an air inlet 1a into which a gas of solid impurities enters and an air outlet 1b from which a pure gas is discharged are provided on the filter 1, respectively. The bottom of the filter cartridge 20 in this embodiment is connected to the sedimentation tube 10 by a bottom plate 21. Specifically, the perpendicularity between the upper surface of the bottom plate 21 and the center line of the filter element 20 is ensured, which is beneficial to the tightness between the filter element 20 and the upper surface of the seat plate 10.

In order to ensure the tightness of the filter cartridge, the centering assembly 30 in this embodiment further comprises a centering assembly 30 disposed in the filter 1, wherein the centering assembly 30 in this embodiment comprises a centering frame 31 disposed on the filter cartridge 20 and capable of ensuring that the center line of the filter cartridge 20 is parallel to the center line of the filter 1, a centering disc 32 disposed on the filter cartridge 20 and capable of ensuring that the upper and lower end surfaces of the filter cartridge 20 are sealed, and a pull rod 33 connected with the centering frame 31 and the centering disc 32. The tie rod 33 is connected to the centering bracket 31 and the centering disc 32 by a bolt assembly. Specifically, the bolt assembly comprises a bolt and a nut, and the pull rod 33 is fastened by the nut, so that a certain pretightening force between the end of the filter element 20 and the centering disc 32 is more beneficial, and the sealing is more effective.

Inside the sedimentation tube 10 is a hollow structure 10a, the side of the sedimentation tube 10 in this embodiment being connected to the filter 1 by means of a mounting plate 11.

The working principle of the utility model is as follows:

when gas enters the filter 1 and passes through the sedimentation tube 10, a certain pressure exists, a part of smaller particles enter the sedimentation tube 10, and when the gas rises, bigger solid particles can touch the wall of the sedimentation tube 10, so that the lift force can be lost, and the bigger solid particles can continuously fall due to gravity, so that the bigger solid particles fall and are separated in the process, the tiny materials enter the filter element 20, and the purer gas is discharged from the air outlet 1b at one side of the top of the filter 1 through secondary separation of the filter element 20.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
