Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically a multi-filtration drying device. Background Technology
[0002] Drying equipment is widely used in many industries such as food, pharmaceuticals, and chemicals. In the well-known technical fields, the pharmaceutical, chemical, pesticide, and food industries often need to use equipment such as vacuum filter presses, filter presses, double cone dryers, and vacuum drying ovens to filter and dry materials.
[0003] Patent (CN217275303U) discloses a filter-type dryer, relating to the technical field of dryers. It includes a housing with a filter assembly inside. The filter assembly includes a cylindrical body, with a conical filter plate fixedly connected to the outer wall of the cylindrical body. The outer wall of the conical filter plate is fixedly connected to the inner wall of the housing. The outer wall of the cylindrical body has evenly spaced first through grooves. A rotating rod is installed inside the cylindrical body, with its top penetrating the inner wall of the cylindrical body. A heating tube is installed on the inner wall of the cylindrical body. This application, through the filter assembly, allows material to fall onto the top of the conical filter plate and slide towards the cylindrical body via the inclined surface of the top of the conical filter plate. The material enters the interior of the cylindrical body evenly through multiple first through grooves for collection, separating the material from small pieces of debris. An arc-shaped plate causes the material to slide and disperse on the top of the bottom plate and be collected through the discharge hole, greatly improving the material recovery efficiency of the dryer.
[0004] The filter-type dryer in the aforementioned patent mainly relies on the downward movement of the material due to its own weight, resulting in poor filtration and drying effects. Utility Model Content

The flexible sealing plate 201 seals the second filter frame 402 on top of the second filter frame 402, and the sealing ring 202 seals the space between the first filter frame 401 and the second filter frame 402.
[0026] In one embodiment, the sealing cap 2 is fixedly connected to the top of the tank body 1 by a number of latches 203. The sealing cap 2 is connected and fixed to the tank body 1 by a number of latches 203, which makes the operation convenient and quick.
[0027] In one embodiment, a support frame 102 is provided on one side of the outer wall of the tank body 1. An L-shaped bracket 103 is hinged to the top of the support frame 102 near the side of the tank body 1. The end of the L-shaped bracket 103 away from the support frame 102 is hinged to the center of the top of the tank body 1. A hydraulic cylinder 104 is hinged to the top of the support frame 102.

[0028] In one embodiment, the tank 1 has a base 105 at its bottom and a plurality of observation windows 106 on its surface. The base 105 supports the bottom of the tank 1, and workers can observe the condition inside the tank 1 through the observation windows 106.
[0029] The working principle of this utility model:
[0030] Refer to the instruction manual appendix Figures 1-5 This utility model comprises a tank body 1, a sealing cover 2, an air inlet pipe 3, a filter frame 4, an exhaust pipe 5, and a drain pipe 6. The tank body 1 provides a drying and filtration space for materials. The sealing cover 2 provides a sealed environment for the tank body 1 to prevent external pollutants from entering the tank body 1 during operation. The filter frame 4 provides a material filtration and containment component inside the tank body 1. The air inlet pipe 3 can serve as an air inlet channel for pressure filtration or vacuum filtration. The exhaust pipe 5 can serve as an exhaust channel for vacuum filtration or pressure filtration. The drain pipe 6 is used to drain waste liquid inside the tank body 1.
[0031] In use, open the sealing cover 2, put the material to be filtered and dried into the filter rack 4, close the sealing cover 2, connect the air inlet pipe 3 to the air supply equipment, open the air extraction pipe 5, and maintain a passage between the air inlet pipe 3 and the air extraction pipe 5. The air supply equipment applies air pressure to the material on the filter rack 4 through the air inlet pipe 3. The air pressure is applied to the surface of the material in the filter rack 4, and the moisture in the material falls down through the filter rack 4 under the compression of the air pressure, thus realizing the pressure filtration and drying treatment of the material. At the same time, the opening of the air extraction pipe 5 can be adjusted to be fully open, three-quarters open, half open, or one-quarter open. With the air supply flow rate of the air inlet pipe 3 remaining constant, the pressure of the pressure filtration and drying treatment can be adjusted, thereby realizing the graded pressure filtration and drying treatment of the material. The operation is convenient and quick.
[0032] Open the air inlet pipe 3 and connect the air extraction device to the air extraction pipe 5. The air extraction device applies suction force to the material on the filter frame 4 through the air extraction pipe 5. The suction force acts on the surface of the material in the filter frame 4, and the moisture in the material falls down through the filter frame 4 under the action of suction force, thereby realizing the filtration and drying treatment of the material. At the same time, the opening of the air inlet pipe 3 can be adjusted to be fully open, three-quarters open, half open, or one-quarter open. With the air extraction power of the air extraction pipe 5 remaining unchanged, the pressure of the filtration and drying treatment can be adjusted, thereby realizing the graded filtration and drying treatment of the material. The operation is convenient and quick.
[0033] This invention can perform pressure filtration or vacuum filtration drying on materials, thereby achieving multiple drying processes and effectively improving the filtration and drying effect of materials.
[0034] The filter frame 4 is designed to include a first filter frame 401 and a second filter frame 402, with filter screens 403 respectively installed at the bottom of both the first filter frame 401 and the second filter frame 402. The first filter frame 401 and the second filter frame 402 can perform dual filtration of materials, which can effectively improve the filtration effect. The support block 404 is used to provide spaced support for the first filter frame 401 and the second filter frame 402, ensuring that the first filter frame 401 and the second filter frame 402 maintain a normal spacing and ensuring the stability of filtration. The first support ring 405 supports the outer wall of the first filter frame 401, and the second support ring 101 provides a support position for the first support ring 405 on the inner wall of the tank 1. When the filter frame 4 is placed inside the tank 1, the first support ring 405 is placed directly on top of the second support ring 101, which ensures the quick placement and installation of the filter frame 4 inside the tank 1 and facilitates the removal of the filter frame 4 from the tank 1 for cleaning.
