Traditional mixing equipment can usually only perform a single functional operation, such as a single mixing equipment, a single filtering equipment, and a single drying equipment. This not only increases the investment cost of equipment and manpower, but also has low work efficiency and cannot quickly complete the drying of materials. In addition, it is very easy to cause pollution to the environment or materials during the process of transferring materials.

[0003] The Chinese patent application number CN201210436395.0 discloses a multifunctional machine for filtering, washing and drying, which integrates the three functions of filtering, washing and drying, reduces the investment cost of equipment and manpower, improves work efficiency, and avoids pollution caused by material transfer. The inner cavity of the cylinder of this multifunctional machine for filtering, washing and drying adopts a single stirring paddle, which stirs the material to achieve washing and drying heating. The area that can be stirred by a single stirring paddle is relatively limited, which will cause the material outside the stirring area to not be fully stirred by the stirring paddle, resulting in insufficient washing, which not only reduces the washing efficiency, but also affects the output quality and efficiency of the finished product.

[0027] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, at least one folding paddle assembly 2 and at least one bottom scraping paddle assembly 3 are arranged inside the container assembly 1 of the three-in-one filtering, washing and drying device of the present invention, and at least one first driving assembly 4 and at least one second driving assembly 5 are arranged on the top of the container assembly 1. One first driving assembly 4 is connected to one folding paddle assembly 2 to drive one folding paddle assembly 2, and one second driving assembly 5 is connected to one bottom scraping paddle assembly 3 to drive one bottom scraping paddle assembly 3. In this embodiment, two folding paddle assemblies 2 and one bottom scraping paddle assembly 3 are arranged in the container assembly 1, and the two folding paddle assemblies 2 are arranged on opposite sides of the bottom scraping paddle assembly 3. When the folding paddle assembly 2 rotates, a downward force is generated, which will press the material downward in one direction.

[0029] like Figure 1 , Figure 2As shown, the container assembly 1 includes an upper cylinder 11 and a lower cylinder 12. The upper cylinder 11 is supported by a bracket 13, and the lower cylinder 12 is detachably connected to the bottom of the upper cylinder 11. After the lower cylinder 12 is removed from the upper cylinder 11, it can be moved out from the bottom of the upper cylinder 11. A pneumatic assembly 6 is arranged on the side wall of the upper cylinder 11, and a plurality of lifting assemblies 7 are arranged below the lower cylinder 12. The plurality of lifting assemblies 7 can drive the lower cylinder 12 to rise and fall. Each lifting assembly 7 is provided with a cylinder 71 and a positioning device 72. The pneumatic assembly 6 provides compressed air to the cylinder 71 to lift and fall the cylinder 71. The lifting and falling of the cylinder 71 controls the lifting and falling of the lower cylinder 12. The positioning device 72 is used to position the lower cylinder 12.

[0030] like Figure 2 As shown, the outer periphery of the barrel 111 of the upper barrel 11 is provided with a jacket 112 and a heat preservation layer 113, and the jacket 112 is located between the barrel 111 and the heat preservation layer 113. A heating medium can be circulated in the jacket 112, and the heating medium circulates in the jacket 112 to heat the material inside the container assembly 1, thereby increasing the drying speed. The heat preservation layer 113 can have a heat preservation effect on the material inside the container assembly 1, which is more conducive to improving the drying efficiency, and improving the output quality and efficiency of the finished product. A feed port 15 and a spray port 16 are provided at the top of the upper barrel 11, and the material is input from the feed port 15, and the washing liquid is sprayed from the spray port 16 to spray and wash the material. A discharge port 17 is provided at the bottom of the upper barrel 11, and the washed and dried material is discharged from the discharge port 17. The lower cylinder 12 is a spherical cap-shaped cylinder, and a filter assembly 14 is laid flat on the top thereof. The filter assembly 14 includes a filter cloth 141, a filter plate 142 and a grid plate 143 arranged in sequence from top to bottom. After the washing liquid washes the material, it is filtered by the filter assembly 14 and enters the lower cylinder 12. A liquid outlet 18 is provided at the bottom of the spherical cap of the lower cylinder 12, and the washing liquid entering the lower cylinder 12 is discharged from the liquid outlet 18. A plurality of support rods 121 are vertically extended downward from the bottom of the lower cylinder 12, and a roller 122 is provided at the bottom of the support rod 121. After the lower cylinder 12 is lowered and placed on the bottom surface, it can be moved outward by the roller 122, so as to facilitate the cleaning of the residual material on the filter assembly 14.

[0031] like Figure 3 As shown, the folding paddle assembly 2 includes a folding paddle main shaft 21 and a plurality of folding paddle blades 22. The plurality of folding paddle blades 22 are arranged on the folding paddle main shaft 21 at intervals from top to bottom. Each folding paddle blade 22 is radially arranged on the folding paddle main shaft 21. The blades on both sides of the folding paddle main shaft 21 are inclined downward, and the inclination directions of the blades on both sides are opposite.

[0032] like Figure 4As shown, the scraping paddle assembly 3 includes a scraping paddle main shaft 31, a scraping paddle blade 32, a half paddle blade 33 and a rotatable joint 39. The scraping paddle blade 32 and the half paddle blade 33 are arranged on the scraping paddle main shaft 31 at intervals. The scraping paddle blade 32 is located at the bottom of the scraping paddle main shaft 31, and the half paddle blade 33 is located at the middle and lower part of the scraping paddle main shaft 31; the joint 39 is connected to the top of the scraping paddle main shaft 31. Figure 1 As shown, the bottom scraping blade 32 of the bottom scraping paddle assembly 3 is located below the lowest folding blade 22 of the folding paddle assembly 2, and the top view projection surface of the folding paddle 22 is located within the top view projection surface area of ​​the bottom scraping blade 32, that is, the stirring area of ​​the bottom scraping blade 32 includes the stirring area of ​​each folding paddle assembly 2; the half blade 33 of the bottom scraping paddle assembly 3 is located between two adjacent folding blades 22 of the folding paddle assembly 2, and the two sides of the half blade 33 extend outward to be located below the folding blade 22; the stirring area of ​​the bottom scraping paddle assembly 3 is close to the folding paddle assembly The stirring areas of the folding paddle assembly 2 are staggered, which is more conducive to covering various areas inside the container assembly 1, expanding the stirring area range, fully washing the materials, improving the washing efficiency, and improving the output quality and efficiency of the finished product; and the folding paddles 22 of the folding paddle assembly 2 and the half paddles 33 of the scraping paddle assembly 3 can press the floating materials downward when they rotate, so that the floating materials can be stirred by the paddles, ensuring that the floating materials can also be stirred and washed by the stirring blades, so that the materials can be washed more fully, the washing efficiency is higher, and the output quality and efficiency of the finished product are higher. The scraping blade 32 of the scraping paddle assembly 3 is close to the top surface of the filter assembly 14. There is a spacing between the bottom surface of the scraping blade 32 and the top surface of the filter assembly 14, and the spacing value is about 5 to 10 mm. The scraping blade 32 ensures that the filter assembly 14 does not interfere with the rotation of the scraping paddle assembly 3, while also allowing the scraping blade 32 to stir the material that has sunk to the bottom of the filter assembly 14, so that the material that has sunk to the bottom can also be stirred and washed by the stirring blade, so that the material washing is more complete, the washing efficiency is higher, and the output quality and efficiency of the finished product are higher.

[0033] like Figure 5 , Figure 6 As shown, the bottom scraping paddle main shaft 31 of the bottom scraping paddle assembly 3 is a hollow shaft, and a hollow medium pipe 393 is vertically connected to the joint 39. The medium pipe 393 is vertically inserted into the bottom scraping paddle main shaft 31 along the axial direction, and an outer channel 311 and an inner channel 312 are separated inside the bottom scraping paddle main shaft 31. The outer channel 311 is an annular channel between the medium pipe 393 and the bottom scraping paddle main shaft 31, and the inner channel 312 is a central channel of the medium pipe 393. A medium inlet 391 and a medium outlet 392 are provided on the joint 39, and the medium inlet 391 is connected to the inner channel 312, and the medium outlet 392 is connected to the outer channel 311.

[0034] like Figure 5 , Figure 7As shown, a shaft sleeve 34 is fixedly inserted in the middle of the scraping blade 32 of the scraping blade assembly 3, and is sleeved to the bottom of the scraping blade main shaft 31 through the shaft sleeve 34. A spacer 35 is arranged in the shaft sleeve 34. The spacer 35 is inserted between the scraping blade main shaft 31 and the medium pipe 393 and blocked in the outer channel 311. The medium pipe 393 passes through the center of the spacer 35. The spacer 35 blocks the outer channel 311 from the bottom end of the inner channel 312 to prevent the outer channel 311 from being directly connected to the bottom end of the inner channel 312. The bottom cover of the scraping blade main shaft 31 and the shaft sleeve 34 is provided with a bottom cover 36 to cover the bottom opening of the scraping blade main shaft 31 and the shaft sleeve 34.

[0035] like Figure 4 , Figure 8 As shown, the bottom scraping blade 32 is an arc blade with a triangular longitudinal section, and the arc bending directions of the blades on the two sides of the bottom scraping blade main shaft 31 are opposite. The bottom scraping blade 32 adopts an arc blade, which has a larger stirring contact area, a larger washing area and a larger heating and drying area, and a better washing effect and heating and drying effect. When the bottom scraping paddle assembly 3 rotates, it rotates forward along the arc direction of the bottom scraping blade 32, and it rotates reversely against the arc direction of the bottom scraping paddle assembly 3: when washing materials, the bottom scraping paddle assembly 3 rotates reversely, and the bottom scraping blade 32 can smooth the cracks on the surface of the filter cake formed by the bottom material to prevent the detergent from breaking along the cracks; when drying materials, the bottom scraping paddle assembly 3 rotates forwardly, and the bottom scraping blade 32 can scrape the filter cake formed by the bottom material layer by layer, heat the wet filter cake evenly, accelerate the evaporation of the detergent, and dry the materials more fully; when discharging materials, the bottom scraping paddle assembly 3 rotates forwardly, and the bottom scraping blade 32 can scrape the dry materials and push the materials out of the discharge port 17. The top angle of the triangular longitudinal section corresponds to the top edge of the scraping blade 32, and the bottom edge of the triangle corresponds to the bottom surface of the scraping blade 32. The top edge of the scraping blade 32 is a sharp edge, which is more conducive to stirring the floating materials. The bottom surface of the scraping blade 32 is a flat surface, which is more conducive to stirring and rubbing the sinking materials, driving the sinking materials to rotate together, so that the sinking materials are fully washed and dried, and the output quality and efficiency of the finished product are improved. Figure 7 , Fig. 9As shown, the bottom scraping blade 32 has a cavity inside, and a partition 323 is horizontally arranged in the internal cavity. The partition 323 divides the internal cavity into an inner lower cavity 321 and an inner upper cavity 322. There is a distance between the outer edge of the partition 323 and the outer wall of the bottom scraping blade 32 to form a flow channel 324. The flow channel 324 connects the inner lower cavity 321 and the inner upper cavity 322. A medium outflow channel 37 and a medium inflow channel 38 are provided on the wall surface of the shaft sleeve 34 and the bottom scraping paddle main shaft 31. The medium outflow channel 37 connects the inner channel 312 with the inner lower chamber 321, and the medium inflow channel 38 connects the inner upper chamber 322 with the outer channel 311. Thus, a heating medium circulation channel is formed inside the bottom scraping paddle assembly 3, which includes a medium inlet 391 → inner channel 312 → medium outflow channel 37 → inner lower chamber 321 → flow channel 324 → inner upper chamber 322 → medium inflow channel 38 → outer channel 311 → medium outlet 392. The heating medium flows in the circulation channel to dry the material. The medium circulates in the circulation channel, which avoids the heating medium from being stagnant or staying inside the bottom scraping paddle assembly 3, thereby ensuring the drying effect and improving the drying efficiency.

[0036] When the present invention is actually used, the material is input into the container assembly 1 from the feed port 15, and the washing process is first performed: the spray port 16 sprays washing liquid into the container assembly 1 to spray and wash the material, and the folding blade paddle assembly 2 and the scraping bottom paddle assembly 3 are driven by the corresponding driving assembly to rotate at high speed. At this time, the scraping bottom paddle assembly 3 rotates in the opposite direction to stir and wash the material. After the washing liquid washes the material, it is filtered through the filter assembly 14 and then enters the lower cylinder 12 and is discharged from the liquid outlet 18. After the washing operation is completed, the material continues to undergo a drying process in the container assembly 1: the heating medium is circulated into the jacket 112 of the upper cylinder 11 and the circulation channel of the scraping bottom paddle assembly 3 respectively, and the material is heated and dried. During the drying process, the folding blade paddle assembly 2 and the scraping bottom paddle assembly 3 keep rotating at high speed, and the scraping bottom paddle assembly 3 rotates forwardly. After the drying operation is completed, the folding blade paddle assembly 2 stops rotating, and the scraping bottom paddle assembly 3 keeps rotating at high speed. At this time, the scraping bottom paddle assembly 3 rotates forwardly to push the material to the discharge port 17 for discharge. After the discharge is completed, the connection of the lower cylinder 12 is removed, and the lifting assembly 7 moves the lower cylinder 12 down to the ground. After the lower cylinder 12 is moved out, the residual materials on the filter assembly 14 can be cleaned.

[0037] The above description is an explanation of the present invention, not a limitation of the present invention. The present invention may be modified in any form without violating the spirit of the present invention.
