Technical Field

[0001] The utility model belongs to the technical field of dryers and relates to a filter cloth installation structure of a cylindrical cone filter 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 filter structure of this structure includes a first filter assembly, which includes a filter cloth and a pressing plate. After the filter cloth has been used for a period of time, various impurities will adhere to the filter cloth, and it needs to be cleaned or replaced. However, the filter cloth and the pressing plate of the first filter assembly of this structure are integrated into one, and the filter cloth cannot be removed, which makes it difficult to clean and replace the filter cloth. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art, proposes a mounting structure for filter cloth of a cylindrical cone filter dryer, and solves the technical problem of how to make the filter cloth easy to clean and replace.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a mounting structure for filter cloth of a cylindrical cone filter dryer, the dryer includes a lower cone with a filtrate cavity inside, the bottom of the lower cone has a filtrate outlet connected to the filtrate cavity, characterized in that the inner wall of the lower cone has a plurality of first filtrate holes, the mounting structure includes a conical pressing plate, the pressing plate has a plurality of second filtrate holes, the top of the pressing plate has an annular pressing edge protruding outward along the circumferential direction, the filter cloth is conical, and the top of the filter cloth has an annular flange protruding outward along the circumferential direction The top of the lower cone has an annular step groove, the filter cloth is arranged against the inner wall of the lower cone, the annular flange is arranged against the step surface of the step groove, the pressing plate presses the filter cloth against the inner wall of the lower cone, the annular pressing edge presses the annular flange against the step surface, a fastener passes through the annular pressing edge and the annular flange and is inserted into the lower cone, so that the pressing plate is detachably connected to the lower cone, and the cavity in the dryer is connected to the filtrate cavity through the second filtrate hole, the filter cloth, and the first filtrate hole.

[0007] During installation, first place the filter cloth against the inner wall of the lower cone, and place the annular flange against the step surface of the step groove, then place the pressing plate so that the pressing plate presses the filter cloth against the inner wall of the lower cone, and the annular pressing edge presses the annular flange against the step surface, and then fixes the pressing plate to the lower cone through the fasteners. The mixed liquid in the dryer cavity first passes through the second filtrate hole, then is filtered by the filter cloth, and then the filtered filtrate enters the filtrate cavity through the first filtrate hole, and finally is discharged through the filtrate outlet. When the filter cloth needs to be cleaned or replaced after filtering for a period of time, loosen the fasteners, first remove the pressing plate, and then take out the filter cloth. The filter cloth is easy to take out, so that the filter cloth is easy to clean and replace.

The positioning column plays a positioning role, so that the filter cloth and the pressing plate are arranged at the set position, so that the filter cloth will not deviate from the set position, so that the filter cloth has a better filtering effect. At the same time, the positioning column is inserted into the first positioning hole and the second positioning hole, and the positioning column will not hinder the removal of the pressing plate and the filter cloth.

[0009] In the above-mentioned installation structure of the filter cloth of the cylindrical cone filter dryer, the annular pressing edge is entirely located in the step groove, and the annular flange is entirely located in the step groove. The structure is compact, so that the setting of the annular pressing edge and the annular flange will not hinder the connection between the lower cone and the upper cylinder.

[0010] In the above-mentioned installation structure of the filter cloth of the cylindrical cone filter dryer, the flow cross-sectional area of ​​the second filtrate hole is larger than the flow cross-sectional area of ​​the first filtrate hole. This structure allows the mixed liquid in the dryer cavity to flow to the filter cloth better, and the filtrate after being filtered by the filter cloth can flow to the filtrate cavity better.

[0011] In the installation structure of the filter cloth of the cylindrical cone filter dryer, three adjacent first filtrate holes are arranged in an equilateral triangle, and three adjacent second filtrate holes are arranged in an equilateral triangle, so that the positions of the first filtrate holes and the second filtrate holes are arranged reasonably, the flow cross-sectional area is large, and the filtering speed is improved.

[0012] In the above-mentioned installation structure of the filter cloth of the cylindrical cone filter dryer, the bottom of the pressing plate, the bottom of the filter cloth and the bottom of the conical lower cone are flush with each other. This structure can achieve the best filtering effect for the mixed liquid in the bottom of the dryer cavity.

[0013] In the above-mentioned installation structure of filter cloth of cylindrical-cone filter-dryer, the fastener is a bolt or a screw.

[0014] In the above-mentioned installation structure of filter cloth of cylindrical-cone filter-dryer, the pressing plate is made of metal material.

[0015] Compared with the prior art, the installation structure of the filter cloth of the cylindrical-conical filter dryer provided by the utility model has the following advantages:

[0016] 1. This installation structure presses the filter cloth through the pressing plate, so that the position of the filter cloth will not deviate from the set position. At the same time, the pressing plate is detachable. The filter cloth can be taken out by removing the pressing plate, so that the filter cloth is easy to clean and replace.

[0017] 2. This installation structure positions the annular flange and the annular pressing edge through fasteners and positioning columns, so that the positions of the pressing plate and the filter cloth are accurate, and the filter cloth is located at the set position without deviation, thereby improving the filtering effect of the filter cloth.
