Description

Technical Field

[0001] The utility model belongs to the technical field of dryers and relates to a filtering structure of a cylindrical cone type filtering dryer. Background Art

[0002] The cylindrical-conical filter-dryer is a device that integrates a filter, a washing machine and a dryer. The cylindrical-conical filter-dryer has multiple functions such as reaction, filtering, washing and drying.

[0003] Existing cylindrical-conical filter dryers, for example, Chinese patent literature discloses a filtering structure of a cylindrical-conical filter washing and drying machine [patent number: 202223040171.6; application publication number: CN218686972U]. The dryer includes a cylinder and a cone detachably fixed to the bottom of the cylinder. The filtering structure includes a first filter assembly arranged along the inner side wall of the cone and a second filter assembly arranged in an installation opening at the bottom of the cone. The second filter assembly is located below the first filter assembly in the vertical direction, and a sealing gasket is provided between the first filter assembly and the second filter assembly.

[0004] The filtering structure of this structure has a filtrate cavity inside the cone, and a filtrate outlet at the bottom of the cone, which is connected to the filtrate cavity. The filtrate in the cylinder enters the filtrate cavity after being filtered by the first filter component. However, since the filtrate outlet is located at the bottom of the cone, new filtrate is required to fill the filtrate cavity after the filtrate at the bottom of the filtrate cavity flows out. A small part of the filtrate flows down from the filtrate cavity, and most of the filtrate enters the filtrate cavity from the bottom of the cylinder through the bottom of the first filter component for filling. That is, the bottom of the first filter component plays the greatest filtering role, while the first filter component in other areas plays a relatively small filtering role, which leads to uneven filtering in various areas of the first filter component, reducing the filtering effect of the first filter component. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and proposes a filtering structure of a cylindrical cone filter dryer, and solves the technical problem of how to make each area of ​​the filtering structure filter evenly and improve the filtering effect of the filtering structure.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a filtering structure of a cylindrical cone filter dryer, the dryer includes a lower cone with a filtrate cavity inside, characterized in that the filtering structure includes a filter screen, a spacer ring fixedly connected to the middle of the filtrate cavity and a plurality of filtrate holes located on the inner side wall of the lower cone, the filter screen is arranged close to the inner side wall of the lower cone, the spacer ring divides the filtrate cavity into two upper and lower non-connected filter cavities, an upper filtrate outlet is provided in the middle of the lower cone, and a lower filtrate outlet is provided at the bottom of the lower cone, the cavity in the dryer is connected to the upper filtrate outlet through the filter screen, the filtrate holes, and the upper filter cavity, and the cavity in the dryer is also connected to the lower filtrate outlet through the filter screen, the filtrate holes, and the lower filter cavity.

[0007] The mixed liquid is placed in the cavity in the dryer, and part of the mixed liquid passes through the filter screen and enters the upper filter chamber through the filtrate hole, and is finally discharged from the upper filtrate outlet. The remaining part of the mixed liquid passes through the filter screen and enters the lower filter chamber through the filtrate hole, and is finally discharged from the lower filtrate outlet. The filtering structure divides the filtrate chamber into two upper and lower unconnected upper filter chambers and lower filter chambers by arranging a partition ring in the middle of the filtrate chamber. The filtrate in the upper filter chamber is discharged through the upper filtrate outlet, the mixed liquid passes through the upper filter screen and enters the upper filter chamber, the filtrate in the lower filter chamber is discharged through the lower filtrate outlet, and the mixed liquid passes through the lower filter screen and enters the lower filter chamber, so that the mixed liquid passes through each area of ​​the filter screen, so that the distribution of the mixed liquid through the filter screen is more uniform, so that each local area of ​​the filter screen plays a filtering role, the filtering effect of the filter screen is improved, and the service life of the filter screen is extended. Moreover, the filtrate outflows in the upper filter chamber and the lower filter chamber do not interfere with each other, and the arrangement of the upper filtrate outlet and the lower filtrate outlet increases the discharge speed of the filtrate, thereby increasing the filtration speed of the filtration structure.

[0008] In the filtering structure of the above-mentioned cylindrical cone filter-dryer, the lower cone includes a main body, a conical upper porous plate and a conical lower porous plate, the bottom of the upper porous plate and the top of the lower porous plate are both welded and fixedly connected to the spacer ring, the upper porous plate and the lower porous plate form the inner side wall of the lower cone, the filtrate hole is located in the upper porous plate and the lower porous plate, the upper filter chamber is formed between the upper porous plate, the spacer ring and the main body, and the lower filter chamber is formed between the lower porous plate, the spacer ring and the main body. This structure allows the upper porous plate and the lower porous plate to be fixedly connected to the main body, integrating the integral structure and improving the stability of the filtering structure.

[0009] In the above-mentioned filter structure of the cylindrical cone filter dryer, there is a gap between the bottom of the upper porous plate and the top of the lower porous plate. The gap is the welding seam, which can improve the firmness of welding the upper and lower porous plates with the spacer ring.

[0010] As another case, in the filtering structure of the above-mentioned cylindrical cone filter-dryer, the lower cone includes a main body and a conical porous plate, the top of the porous plate has a fixing ring, the bottom has a positioning ring, the fixing ring is detachably sealed and connected to the top of the main body, the positioning ring is detachably sealed and connected to the bottom of the main body, the middle of the porous plate is against the spacer ring, the porous plate is the inner side wall of the lower cone, and the filtrate hole is located in the porous plate. This structure makes the porous plate and the main body a split structure, the porous plate can be disassembled and replaced, and the flexibility of use and versatility are improved.

[0011] In the above-mentioned filter structure of the cylindrical cone filter dryer, the upper filtrate outlet is arranged adjacent to the spacer ring, and the bottom surface of the upper filtrate outlet is located below the top surface of the spacer ring in the vertical direction. This structure ensures that the filtrate in the upper filter chamber can be discharged cleanly.

[0012] In the filter structure of the above-mentioned cylindrical cone filter dryer, the filter screen is in a cone shape and is made of metal material. This structure enables the filter screen to be welded and fixedly connected with the porous plate, so that the filter screen and the porous plate are integrated as a whole.

[0013] In the above-mentioned filtering structure of the cylindrical cone filter-dryer, the interior of the lower cone also has a heat exchange chamber, and the heat exchange chamber is in contact with the filtrate chamber.

[0014] Compared with the prior art, the filtration structure of the cylindrical cone filter dryer provided by the utility model has the following advantages:

[0015] 1. This filtering structure divides the filtrate cavity into two unconnected upper and lower filtering cavities through a spacer ring, so that the mixed liquid in the cavity of the dryer is filtered relatively evenly through each area of ​​the filter net, so that each area of ​​the filtering structure is filtered evenly, the filtering effect of the filter net is improved, and the service life of the filter net is extended.

[0016] 2. The filtrate outflows from the upper filter chamber and the lower filter chamber of the filtration structure do not interfere with each other. The filtrate in the upper filter chamber is discharged through the upper filtrate outlet, and the filtrate in the lower filter chamber is discharged through the lower filtrate outlet, thereby increasing the filtrate discharge speed and thus increasing the filtration speed of the filtration structure.
