Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically a three-in-one dryer for filtration, washing, and drying. Background Technology

[0002] In traditional chemical and pharmaceutical manufacturing processes, materials after solid-liquid separation typically require three separate steps: filtration, washing, and drying. This usually necessitates the use of three different pieces of equipment, such as filter presses, washing tanks, and dryers. The materials need to be transferred between these devices multiple times.

[0003] However, the material transfer process is time-consuming and labor-intensive, increasing the workload of workers. Furthermore, during open or semi-open transfers, materials are easily contaminated by the external environment or pose a hazard to operators and the environment due to their inherent properties (such as toxicity or flammability). At the same time, material loss is also difficult to avoid. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please see Figure 1 In this embodiment: a three-in-one dryer for filtering, washing and drying includes a tank 1, a drive motor 3 is provided on the tank 1, a stirring assembly 2 is installed at the output end of the drive motor 3, the stirring assembly 2 is located inside the tank 1, a lifting mechanism 4 is installed on one side of the tank 1, the drive motor 3 is connected to the lifting mechanism 4, a filter disc 5 is installed inside the tank 1, and a discharge port 6 is provided on the lower side of the tank 1. In this embodiment, the slurry is pumped into the tank 1 from the inlet. By pressurizing or vacuuming, the liquid passes through the filter disc 5, while the solid is trapped to form a filter cake. At this time, the drive mechanism 3 drives the stirring assembly 2 via a reducer. The lifting mechanism 4 is a hydraulic station that controls the hydraulic cylinder to drive the entire stirring assembly 2 vertically up and down. The stirring assembly 2 can slowly descend and rotate forward, smoothing the surface of the filter cake to prevent cracking and improve filtration efficiency. Then, the stirring assembly 2 is lifted, and washing liquid is added through the washing liquid inlet. The stirring assembly 2 is then started to rotate, allowing the washing liquid to fully mix with the filter cake, achieving displacement washing. For the purpose of heavy slurry washing, the stirring is stopped, and the filtration step is repeated to drain the washing liquid. After the filter cake is washed and qualified, the stirring component 2 is lowered to the surface of the filter cake and the rotation is started to loosen and break the filter cake. At the same time, hot water or steam is introduced into the jacket 8 for heating, and the tank is evacuated. Through the dual action of heating and depressurization, the solvent in the material is rapidly evaporated and extracted by the vacuum system. After the material is dried and qualified, the heating and vacuuming are stopped, the side discharge port 6 is opened, the stirring component 2 rotates in the opposite direction and slowly descends, and the powdered finished product is automatically pushed out from the discharge port 6 like a screw conveyor, completing the entire process.

[0016] Furthermore, the stirring assembly 2 includes a main shaft 201, one end of which is fixedly connected to the output end of the drive motor 3, and stirring blades 202 are fixedly connected to the outer wall of the main shaft 201.

[0017] Preferably, an anti-backflow valve 7 is installed on the other side of the lower part of the tank body 1; a jacket 8 is provided on the outer wall of the tank body 1; a balance valve 9 is installed on one side of the outer wall of the tank body 1; and the stirring blade 202 is S-shaped.

[0018] The working principle and usage process of this utility model are as follows: During the filtration stage, the slurry is pumped into the tank 1 through the inlet. By pressurizing or vacuuming, the liquid passes through the filter disc 5, while the solid is trapped to form a filter cake. At this time, the stirring device assembly 2 can slowly descend and rotate forward. Then, the drive motor 3 is started to drive the main shaft 201 to rotate, which in turn drives the stirring blades 202 to rotate, thus smoothing the surface of the filter disc 5, preventing cracking, and improving filtration efficiency. During the washing stage, the stirring assembly 2 is lifted by activating the lifting mechanism 4, and washing liquid is added through the washing liquid inlet. The stirring assembly 2 is then started to rotate, which in turn drives the drive motor 3 to drive the main shaft 201 to rotate. The main shaft 201 drives the stirring blades 202 to rotate, thereby enabling the washing liquid and filter cake to be fully mixed, achieving the desired effect. After the washing or re-slurry washing is completed, the stirring is stopped, and the filtration step is repeated to drain the washing liquid. During the drying stage, after the filter plate 5 is washed and qualified, the stirring component 2 is lowered to the surface of the filter plate 5, and the drive motor 3 is started to drive the main shaft 201 to rotate. The main shaft 201 drives the stirring blades 202 to rotate to loosen and break the filter cake. At the same time, hot water or steam is introduced into the jacket 8 for heating, and the tank 1 is evacuated. Through the dual action of heating and depressurization, the solvent in the material is rapidly evaporated and extracted by the vacuum system. After the material is dried and qualified, the heating and vacuuming are stopped, the side discharge port 6 is opened, the stirring component 2 rotates in the opposite direction and slowly descends, and the powdered finished product is automatically pushed out from the discharge port 6 like a screw conveyor, completing the entire process.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
