Subsequent embodiments will not explain this in detail.

[0031] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0032] A type of rotary filter washing and drying machine agitator, such as Figures 1-2As shown, the device includes a rotating shaft 1, a first stirring blade 2, and a second stirring blade 3. The first stirring blade 2 and the second stirring blade 3 are fixed at different heights on the rotating shaft 1, forming a double-layer blade effect. The height of the second stirring blade 3 is higher than that of the first stirring blade 2. The design of fixing the first stirring blade 2 and the second stirring blade 3 at different heights on the rotating shaft 1 to form a double-layer blade allows the agitator to perform three-dimensional stirring of the material in the dryer in the vertical direction.

[0033] like Figure 4 As shown, the first stirring paddle 2 includes a first stirring shaft sleeve 21, a first stirring blade 22, and a first stirring arm 23. The first stirring shaft sleeve 21 is sleeved on the outside of the rotating shaft 1 and fixedly connected to the rotating shaft 1. The first stirring blade 22 is fixedly connected to the outer periphery of the first stirring shaft sleeve 21. The first stirring arm 23 is fixedly connected above the end of the first stirring blade 22 and perpendicular to the length direction of the first stirring blade 22. Figure 6 As shown, the second stirring paddle 3 includes a second stirring shaft sleeve 31, a second stirring blade 32, and a second stirring arm 33. The second stirring shaft sleeve 31 is sleeved on the outside of the rotating shaft 1 and fixedly connected to the rotating shaft 1. The second stirring blade 32 is fixedly connected to the outer periphery of the second stirring shaft sleeve 31. The second stirring arm 33 is fixedly connected above the end of the second stirring blade 32 and its upper end is bent toward the second stirring shaft sleeve 31 so that it forms a single-arm U-shaped structure with the second stirring blade 32.

[0034] like Figure 1 , Figure 3 As shown, there are two first agitator blades 22, and the two first agitator blades 22 are centrally symmetrical with respect to the central axis of the rotating shaft 1. The two first agitator blades 22 cooperate to form a double-arm U-shaped structure; there are also two second agitator blades 32, and the two second agitator blades 32 are centrally symmetrical with respect to the central axis of the rotating shaft 1; the first agitator blades 22 and the second agitator blades 32 are staggered at 90°. The two first agitator blades 22 and the two second agitator blades 32 work together to significantly and effectively improve the washing and drying effects.

[0035] Furthermore, the height of the first stirring shaft sleeve 21 relative to the rotating shaft 1 is adjustable, and the height of the second stirring shaft sleeve 31 relative to the rotating shaft 1 is also adjustable, making the heights of the first stirring blade 22 and the second stirring blade 32 adjustable to meet the washing and drying needs of different materials. Specifically, the first stirring shaft sleeve 21 and the rotating shaft 1 are keyed together to achieve synchronous rotation, and their relative height positions are fixed by bolts. The height of the first stirring blade 22 can be adjusted within a certain range by tightening or loosening the bolts. Similarly, the second stirring shaft sleeve 31 and the rotating shaft 1 are keyed together to achieve synchronous rotation, and their relative height positions are fixed by bolts. The height of the second stirring blade 32 can be adjusted within a certain range by tightening or loosening the bolts. Since the keys forming the mating connections are all located on the rotating shaft 1, the height adjustment range of the first stirring blade 22 and the second stirring blade 32 is set based on the length range of the keys.

[0036] Specifically, such as Figure 4As shown, the first stirring blade 22 has a first blade 221 and a second blade 222; the first blade 221 is a flat plate arranged in the longitudinal direction and its bottom protrudes relative to the bottom of the first stirring shaft sleeve 21. The portion of the first blade 221 that protrudes relative to the first stirring shaft sleeve 21 has a scraping surface 223 and spaced notches 224; the second blade 222 is connected to the upper end of the first blade 221 and bends at an obtuse angle with the first blade 221, and the longitudinal width of the inner end of the second blade 222 is greater than the longitudinal width of the outer end. The inner bottom end of the first blade 221 is provided with a first stirring bar 225 extending to the bottom of the first stirring shaft sleeve 21. The first stirring blade 22 stirs the slurry at the bottom of the tilting filter washing dryer, requiring continuous stirring and agitation. The first blade 221 and the second blade 222 work together. The first blade 221 can penetrate deep into the slurry at the bottom of the equipment, effectively scraping up the slurry deposited at the bottom, preventing slurry from accumulating and clumping, ensuring that all slurry in the dryer participates in the stirring process, greatly improving the uniformity and efficiency of stirring. After the first blade 221 scrapes up the slurry at the bottom, the second blade 222 can then lift the slurry upwards and spread it outwards. Simultaneously, the longitudinal width of the inner end of the second blade 222 is greater than the longitudinal width of the outer end, creating a gradual dispersion effect from the inside out during the lifting and spreading process, further increasing the range and degree of slurry agitation, allowing slurry from different layers and positions to be fully mixed. When the first blade 221 rotates, the slurry passes through the notch 224, forming an irregular flow, thus generating turbulence in the stirring area. This turbulence breaks the laminar flow of the slurry, causing more collisions and mixing between different parts of the slurry, further improving the mixing effect and quality. The scraper surface 223 closely adheres to the bottom inner wall of the dryer, scraping off the slurry adhering to the bottom. This not only helps prevent slurry residue and solidification at the bottom but also ensures the cleanliness of the dryer's interior, reduces material loss, and improves product recovery rate. The first stirring bar 225 can stir and clean the slurry around the bottom of the first stirring shaft sleeve 21. During the stirring process, the first stirring bar 225 prevents slurry from accumulating at the bottom of the shaft sleeve, avoiding interference with the normal operation of the stirring shaft sleeve due to slurry accumulation. It also helps maintain the cleanliness around the shaft sleeve, extending its service life.

[0037] The second stirring shaft sleeve 31 is fitted at the bottom of the rotating shaft 1, and at least one first stirring bar 225 has a second stirring bar 226 extending to the center of the rotating shaft 1 at its inner end, and the second stirring bar 226 is located below the rotating shaft 1; this further effectively prevents the slurry from accumulating at the bottom of the sleeve.

[0038] The first stirring arm 23 is a flat plate arranged longitudinally, with a longitudinally arranged folded bar 24 connected to its inner end. The folded bar 24 is bent at an obtuse angle to the first stirring arm 23. The first stirring arm 23 can perform a relatively wide stirring action in the longitudinal space within the equipment. Combined with the folded bar 24, the longitudinal range of stirring is further increased, ensuring that slurry at different heights is fully stirred, avoiding dead zones and improving the mixing uniformity of the slurry within the entire dryer. Furthermore, the folded bar 24 alters the flow direction of some materials; some slurry flows along the direction of the folded bar 24, while another part collides and mixes with the slurry flow originally driven by the first stirring arm 23. This interaction of slurry flowing in different directions creates a complex flow field within the dryer, increasing the contact and mixing opportunities between slurries and further enhancing the stirring effect.

[0039] The notch 224 is trapezoidal in shape, wider at the bottom and narrower at the top. During mixing, the larger bottom opening of the trapezoidal notch 224 allows for more effective intake of the slurry from the bottom. When the first stirring blade 22 rotates, a large amount of slurry can flow into the notch 224. As the stirring blade rotates, due to the narrower top of the notch, the slurry is compressed as it flows upwards, causing it to exit from the top of the notch 224 at a faster speed. This intake and discharge process creates a strong localized slurry flow, resulting in more intense collisions and mixing with the surrounding slurry, further improving the mixing degree within the mixing area.

[0040] like Figure 6 As shown, the second stirring blade 32 is a long cylindrical body extending horizontally, and the second stirring arm 33 is a flat plate extending longitudinally. The second stirring blade 32, being a long cylindrical body extending horizontally, pushes the surrounding material into a horizontal annular flow during rotation, and exerts a certain amount of compression and shearing action on the material, breaking up larger material clumps. The second stirring arm 33, being a flat plate extending longitudinally, drives the material into a longitudinal flow during stirring, and also beats and disperses the material during the stirring process, resulting in more effective dispersion of the material within the equipment. These two different material flows intertwine, forming a complex flow pattern, which makes the collision and mixing between materials more thorough, further improving the stirring effect.

[0041] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
