Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] The present invention is an improvement based on the existing filter washing press dryer. An ultrasonic vibration device 2 is added in the container body 1 of the existing filter washing press dryer to disperse materials, vibrate and discharge slag, and clean without dead corners, preventing residual materials from batch change; a polymer microporous tube is used to replace the filter tube in the existing filtration area, and it has a high interception rate and no risk of foreign matter dissolution.

[0020] For the existing filter washing press dryer, the invention patent with the publication number of CN113413662A can be selected. In the present invention, it is incorporated into the present invention in its entirety to explain the specific composition of the filter washing press dryer in the present invention.

[0021] As Figure 1-2 shown, the present invention provides a filter washing press dryer, in which an ultrasonic vibration device 2 is arranged in the container body 1 for dispersing materials, vibrating and discharging slag, and cleaning without dead corners, preventing residual materials from batch change; The filter tube in its filtration area 3 uses a polymer microporous tube, which has a high interception rate and no risk of foreign matter dissolution. The filter tube is installed on a circular row of pipes. The circular row of pipes is made of steel, titanium, or non-metallic materials, specifically, for example, the circular row of pipes disclosed in the invention patent with the publication number of CN113413662A.

[0022] In the present invention, the ultrasonic vibration device 2 includes: A rod-shaped ultrasonic device 21, which is arranged on the side wall of the container body 1; An annular ultrasonic device 22, which is arranged on the bottom of the container body 1.

[0023] The rod-shaped ultrasonic device is a piece of equipment that applies ultrasonic technology to a specific shape, namely, the rod shape. It is commonly used to generate high-intensity ultrasonic vibration waves. The core of this device lies in its ability to convert electrical energy into mechanical vibration, thereby generating ultrasonic waves. In industrial and laboratory environments, the rod-shaped ultrasonic device is widely used due to the flexibility of its form. It can be easily installed inside various containers or pipes, or even directly immersed in liquids. When working, the rod-shaped ultrasonic device generates a cavitation effect in the medium through high-frequency vibration (usually in the range of 20 kHz to several hundred kHz), that is, tiny bubbles are formed in the liquid and quickly collapse, releasing a huge amount of energy. This process can effectively promote the dispersion of solid particles, emulsification, cell disruption, or accelerate chemical reactions in the liquid. At the same time, it can also be used for surface cleaning to remove contaminants that are difficult to peel off because the ultrasonic vibration can penetrate into tiny gaps. In the context of the filtration, washing, and pressing dryer you mentioned, the rod-shaped ultrasonic device is installed on the side wall of the container body, and its main functions include but are not limited to: Disperse materials: Help disperse large particle substances to prevent clogging of the filtration system.

[0024] Vibrate and discharge residue: Promote the shedding of solid particles remaining on the filter medium after filtration through vibration, facilitating cleaning and regeneration.

[0025] Clean without dead corners: The penetration of ultrasonic waves enables every corner inside the container to be subjected to the cleaning effect, improving the cleaning efficiency.

[0026] Therefore, the rod-shaped ultrasonic is not only a physical treatment means but also one of the key technologies to improve filtration efficiency and simplify the maintenance process.

[0027] The ring-shaped ultrasonic device is an ultrasonic emission device designed in a ring shape, mainly used to generate a circumferential ultrasonic field. In industrial applications, especially in the fields of cleaning, homogenization, and reaction promotion, the ring-shaped ultrasonic device demonstrates unique advantages. The working principle and function overview of the ring-shaped ultrasonic device are as follows: Structural features: The ring-shaped ultrasonic device usually consists of a ring-shaped outer shell made of stainless steel or other corrosion-resistant materials, which encloses ultrasonic vibrators (transducers). These vibrators generate ultrasonic vibrations through electromagnetic excitation, and the vibrations are then transmitted to the liquid or slurry in contact with them.

[0028] Installation location: In the present invention, the ring-shaped ultrasonic device is installed at the bottom of the container body. Such a layout is designed to ensure that ultrasonic waves can propagate uniformly upward from the bottom of the container, achieving efficient cleaning of all surfaces inside the container and uniform dispersion of materials.

[0029] Working principle: Through high-frequency vibration (generally from 20 kHz to several hundred kHz), the annular ultrasonic device generates a strong cavitation effect in the liquid medium. This effect includes the formation, growth, and sudden collapse of tiny bubbles, releasing energy shock waves, effectively removing solid deposits adhering to the container wall and other hard-to-reach areas, and at the same time strengthening the mixing and dispersion process of the materials.

[0030] Advantages: Comprehensive cleaning: The annular design ensures that the ultrasonic wave covers the bottom and nearby areas of the container, reducing the cleaning blind spots.

[0031] Efficient material handling: Helps to accelerate the separation of solids and liquids, improving the pretreatment effect before filtration.

[0032] Energy consumption reduction: Compared with traditional mechanical stirring, ultrasonic cleaning and dispersion are more energy-efficient.

[0033] In summary, the annular ultrasonic device plays an important role in improving the cleaning efficiency and promoting the uniform processing of materials in the present invention, and is one of the key components to improve the overall equipment efficiency.

[0034] In the present invention, the filtering area 3 includes an upper filtering area 31 provided at the upper part of the container body 1, a middle filtering area 32 provided in the middle of the container body 1, and a bottom filtering area 33 provided at the bottom of the container body 1.

[0035] In the present invention, both the upper filtering area 31 and the middle filtering area 32 are provided with circular ring-shaped pipes, and the inverted filtering pipes are installed on the circular ring-shaped pipes.

[0036] Preferably, one or more filter plates are provided on the bottom filtering area 33.

[0037] In the present invention, a spray washing device 4 is provided at the top end of the container body 1 to facilitate spraying during the processing.

[0038] In the present invention, an upward discharge device 5 is provided at the bottom of the container body.

[0039] The upward discharge device is a fitting in the filter washing and pressing dryer, mainly used for the discharge process of solid materials or filter residues. Its design purpose is to efficiently and cleanly discharge the filtered and washed materials from the bottom of the container, while reducing material blockage and residue. The specific characteristics and working principle can be summarized as follows: Design features: The upward discharge device usually includes retractable or rotatable discharge components, which can expand outward when opened to increase the discharge port area and ensure smooth material flow. The design emphasizes sealing and self-cleaning capabilities, reducing the risk of material adhesion and cross-contamination.

[0040] Working principle: During operation, through a driving mechanism (such as hydraulic, pneumatic or electric), the components of the discharging device are actuated to gradually unfold and expose the material layer at the bottom of the container. The material slides out of the container along the unfolded discharging surface under the action of gravity or slight auxiliary pushing, and enters the next process or a collecting container. After discharging is completed, the device resets and closes to keep the system sealed and ready for the next round of operation.

[0041] In the present invention, preferably, a telescopic connecting sleeve switching device is adopted. The lifting of the central shaft is controlled by two cylinders to push the sealing sleeve with radial sealing. When it extends, the flow channel opens, and when it contracts, the flow channel closes.

[0042] Application advantages: Improve efficiency: The fast and large-area discharging design reduces the emptying time and increases the production efficiency.

[0043] Reduce losses: The smooth discharging surface and well-controlled discharging rate contribute to reducing material breakage and losses.

[0044] Easy to clean and maintain: The design takes into account the convenience of cleaning and reduces the shutdown maintenance time.

[0045] Flexibility: It is applicable to various material characteristics and throughput, and the unfolding degree and discharging rate can be adjusted according to actual requirements.

[0046] In the present invention, the upward-unfolding discharging device is located at the bottom of the container body and cooperates with ultrasonic cleaning, polymer microporous filter tubes, etc. to jointly form a set of efficient and automated material processing system, ensuring the continuity and efficiency of the entire technological process.

[0047] In the present invention, it further includes: A stirring device 6, which is used to stir the material in the container body 1.

[0048] Among them, preferably, an upper stirring paddle, a middle stirring paddle and a bottom stirring blade are provided on the stirring device 6, and preferably a scraper is provided on the bottom stirring blade for scraping materials or slag.

[0049] The usage method of the present invention is as follows: (1) The stirring device of the present invention needs to be equipped with a frequency converter, and the frequency of each filtration section is adjusted according to the solid content; (2) The filtration medium used in the present invention is a polymer microporous tube. When the equipment is initially fed, the pressure shall not exceed 0.05 MPa, and it starts at low pressure to prevent the initial blockage of the filter tube and plate; (3) Precautions for using the rod-shaped ultrasonic device: The main function of the rod-shaped ultrasonic device is to separate materials and remove the filter cake attached to the filter element. When using, the frequency of the ultrasonic wave needs to be adjusted according to requirements to meet the process requirements; (4)Precautions for using the ring ultrasonic device: The main function of the ring ultrasonic device is to disperse materials, enable the materials to react fully, increase the reaction speed, and prevent the materials from settling quickly. Pay attention to adjusting the frequency of the ultrasonic wave and the installation position at the bottom to meet the process requirements; (5)Precautions for using the hollow plate at the bottom: The bottom adopts a hollow plate structure. During the reaction process, a small amount of materials settling at the bottom float up through internal air bubbling for full reaction to achieve no dead angle. The air source pressure of the bubbling gas must be guaranteed to be 0.4 - 0.6 MPa; (6)According to the process requirements, after the materials are washed, reacted, filtered, and pressed dry in this device, they can be completely transported to other reaction kettles for re - reaction through the upward - spreading discharging device in the middle of the bottom hollow plate, and then transported back to this device for filtration and pressing dry again. The lifting power of the upward - spreading discharging device comes from a cylinder, and the air intake pressure of the cylinder must be guaranteed to be greater than or equal to 0.5 MPa.

[0050] The above is only the preferred specific implementation mode of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, based on the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
