Description

Technical Field

[0001] The utility model relates to the field of drying machine filtering, in particular to a filtering mesh ring. Background Art

[0002] A desiccant generally refers to a compressed air adsorption dryer, which is used for drying air after compression. The desiccant combines the advantages of pressure swing adsorption and temperature swing adsorption, adsorbs at room temperature and high steam partial pressure, and resolves at higher temperature and low steam partial pressure, that is, the moisture adsorbed by the adsorbent during the adsorption process can be completely removed during the regeneration process by relying on the combined action of the thermal diffusion of dry air heating and the low partial pressure. The adsorbed wet air enters the drying tank from the lower tube and flows through the adsorbent bed from bottom to top, and the dry air is discharged from the upper tube. In the process of wet air entering and exiting the drying tank, it is easy to carry desiccant into the pipeline, which will not only block the pipeline but also easily make the air drying effect worse. At present, a filter mesh is set at the inlet and outlet of the drying tank, but the single-layer filter mesh is easily deformed and damaged due to the high pressure during the filtration process, thus affecting the filtration effect. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a filter mesh ring, which has the advantages of solving the problems raised in the above background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A filter mesh ring comprises a mesh ring body, both sides of which are sleeved with mounting bone rings, an inner wall of the mesh ring body is fixedly connected with multiple layers of filter screens, a support assembly is provided on the side of the multiple layers of filter screens away from the mesh ring body, the support assembly comprises a support inner cylinder fixedly connected to the inner wall of the multiple layers of mesh ring, a plurality of filter holes are penetrated through the outer wall of the support inner cylinder, a plurality of telescopic rods are provided between the inner walls of the support inner cylinder, springs are sleeved on the outer sides of the plurality of telescopic rods, a reinforcing mesh ring is sleeved on the outer side of the mesh ring body, a plurality of reinforcing ribs are fixedly connected between the reinforcing mesh ring and the mesh ring body.

[0006] By adopting the above technical solution, the mesh ring body is used to be installed on the wet air inlet and outlet of the drying tank of the dryer. When the air enters the air inlet and outlet of the drying tank, the quality of compressed air filtration can be improved by setting the multi-layer filter screen in the mesh ring body. At the same time, when the compressed air is filtered, strong pressure will be generated. At this time, the support inner tube and the setting of the telescopic rod and the spring in the supporting inner tube play a certain supporting and protective role, avoiding the large pressure from damaging the mesh ring body. At the same time, during the filtering process, the reinforced mesh ring and the reinforcing ribs sleeved on the outside of the mesh ring body can also play a filtering and supporting role, avoiding the huge impact force from damaging the mesh ring body, and reducing the probability of deformation and damage to the mesh ring body.

[0007] It is further provided that: the reinforcing mesh ring is welded in one piece.

[0008] By adopting the above technical solution and strengthening the setting of the network circle, a certain filtering and protective effect can be achieved.

[0009] It is further provided that: the outer side of the spring is coated with an anti-rust layer.

[0010] By adopting the above technical solution, the provision of the anti-rust layer can effectively protect the spring, avoid damage to the spring caused by long-term filtering work, and indirectly increase the service life of the spring.

[0011] It is further configured that: a protective layer is coated on the outer side of the reinforcing rib.

[0012] By adopting the above technical solution, the setting of the reinforcing ribs plays a supporting role to prevent the mesh ring body from deformation and damage. At the same time, the protective layer on the outside of the reinforcing ribs can effectively protect the reinforcing ribs and increase the service life of the reinforcing ribs.

[0013] Further configuration: the filter holes are all fixedly connected with filter meshes

[0014] By adopting the above technical solution, the supporting inner cylinder also plays a supporting and filtering role, and the cooperation of the filter holes in the barrel cover and the filter mesh can improve the filtering quality to a certain extent.

[0015] In summary, the utility model has the following beneficial effects:

[0016] In the utility model, the mesh ring body is used to be installed on the wet air inlet and outlet of the drying tank of the dryer. When the air enters the air inlet and outlet of the drying tank, the multi-layer filter screens in the mesh ring body can improve the quality of compressed air filtration. At the same time, strong pressure will be generated during the compressed air filtration process. At this time, the support inner cylinder and the telescopic rod and spring in the support inner cylinder play a certain supporting and protective role, avoiding the large pressure from damaging the mesh ring body. At the same time, during the filtering process, the reinforced mesh ring and the reinforcing ribs sleeved on the outside of the mesh ring body can also play a filtering and supporting role, avoiding the huge impact force from damaging the mesh ring body, and reducing the probability of deformation and damage to the mesh ring body.
