Description

Technical Field

[0001] The invention relates to the technical field of rake dryers, in particular to a rake dryer with self-cleaning residue. Background Art

[0002] The rake dryer is designed specifically for drying specific materials, particularly heat-sensitive materials and those susceptible to oxidation at high temperatures. Since the material is in powder form after drying, this equipment is ideal for materials requiring a powdered finish. The dried material can be packaged directly without the need for additional pulverization. During the drying process, the inner wall of the drying drum is covered with multiple rake teeth, which scrape and stir the material to achieve uniform drying. Due to this operating characteristic, residue often adheres to the left and right sides of the drying drum and to the rake teeth after drying. In practice, cleaning this residue after drying and collecting the powder has multiple benefits: it can slightly increase total material yield and reduce the subsequent cleaning workload of the drying drum, thereby improving overall production efficiency. Traditionally, material accumulates in the gaps between the discharge pipe, drying chamber, and discharge valve, where the material mixing head cannot reach, making it difficult to dry quickly. Short drying times can also result in poor drying of a small portion of the material at the beginning of discharge.

[0020] 2. The rectangular frame of the residue cleaning mechanism is used to block the rectangular opening. The rotation of the servo motor output end drives the rectangular frame to rotate. The rotation of the rectangular frame drives the limit bar, sliding plate and nozzle to rotate, so that the nozzle rotates to the rectangular opening position. The nozzle is connected to the external air supply equipment. Compressed air is ejected from the nozzle to spray off the residual raw materials on the hollow rod, stirring rod and stirring head, reducing the workload of subsequent cleaning, while slightly increasing the total output of materials and improving overall production efficiency.

[0021] 3. The discharge pipe is sealed by a sealing plate. The first connecting pipe is connected to an external air supply device.

The first fixed pipe is used to support the first connecting pipe to prevent the first connecting pipe from being entangled when the sealing plate moves up and down. The sealing plate seals the discharge pipe on the lower side of the drying box.

The discharge pipe 27 is fixedly installed on the lower side of the drying box 21, and the deflection angles of the stirring head 24 on the left side of the discharge pipe 27 and the stirring head 24 on the right side of the discharge pipe 27 are symmetrical on the left and right. The uniform temperature stirring mechanism 2 also includes: a ventilation component, and the two ventilation components are respectively installed on the left and right sides of the hollow rod 22, and a plurality of rectangular openings 28 are provided on the drying box 21.

[0047] The temperature-uniform stirring mechanism 2 uniformly stirs and heats the raw materials, the residue cleaning mechanism 3 cleans the raw material residue remaining on the temperature-uniform stirring mechanism 2 , and the sealing and blocking mechanism 4 seals and blocks the temperature-uniform stirring mechanism 2 .

[0048] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 12 、 Figure 13As shown, the extension pipe 26 of the temperature-uniform stirring mechanism 2 is connected to the external steam supply equipment. The steam enters from the extension pipe 26, passes through the U-shaped pipe 25, and is discharged from the extension pipe 26. Part of the steam is condensed and also discharged from the extension pipe 26. In order to facilitate the discharge of condensed water, the entire equipment can be installed at an angle, such as installing it with the left higher and the right lower. The steam enters from the left extension pipe 26 and is discharged from the right extension pipe 26. The steam heats the stirring rod 23 and the stirring head 24 in the U-shaped pipe 25, and heats the hollow rod 22 at the same time. The raw materials are stirred and heated by the stirring rod 23 and the stirring head 24 in the drying box 21, thereby improving the uniformity of heating inside the raw materials. The heated and dried raw materials are discharged from the discharge pipe 27.

[0049] The ventilation assembly includes: a fixing plate 29 and a sealing frame 210. The fixing plate 29 is fixedly installed at both ends of the hollow rod 22. The end of the extension tube 26 away from the U-shaped pipe 25 passes through the fixing plate 29 and is fixedly installed on the fixing plate 29.

[0056] like Figure 4 、 Figure 8 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 17As shown, the rectangular frame 32 of the residue cleaning mechanism 3 is used to block the rectangular opening 28, and the output end of the servo motor 31 rotates to drive the rectangular frame 32 to rotate. The rotation of the rectangular frame 32 drives the limit bar 33, the sliding plate 34 and the nozzle 35 to rotate, so that the nozzle 35 rotates to the position of the rectangular opening 28. The nozzle 35 is connected to the external air supply equipment, and compressed air is ejected from the nozzle 35 to spray the raw materials remaining on the hollow rod 22, the stirring rod 23 and the stirring head 24, thereby reducing the workload of subsequent cleaning, and at the same time slightly increasing the total output of the material, thereby improving the overall production efficiency.

[0057] The residue cleaning mechanism 3 also includes: a swinging assembly, which is installed in a rectangular frame 32. The swinging assembly includes: a reciprocating motor 37, a connector 38 and a hose 39. The reciprocating motor 37 is fixedly installed in the rectangular frame 32.

The hose 39 is used to supply air to the nozzle 35.

[0058] The output end of the reciprocating motor 37 of the swing assembly moves left and right, driving the connecting head 38 to move left and right. The left and right movement of the connecting head 38 drives the nozzle 35 to move left and right. The left and right movement of the nozzle 35 drives the sliding plate 34 to move left and right. During the left and right movement of the sliding plate 34, the sliding plate 34 always blocks the strip opening 36, so that the raw material will not enter the rectangular frame 32. At the same time, the nozzle 35 moves left and right to spray air, which improves the cleaning effect.

[0059] The residue cleaning mechanism 3 also includes: a sealing assembly, which is installed on the drying box 21, and the sealing assembly includes: a first sealing ring 310, a second sealing ring 311 and a third sealing ring 312, the first sealing ring 310 is fixedly installed on the rectangular opening 28, the second sealing ring 311 and the third sealing ring 312 are both fixedly installed on the front side of the sliding plate 34, and the third sealing ring 312 is located outside the outer wall of the second sealing ring 311.

When the rectangular frame 32 rotates, the first sealing ring 310 seals the gap between the rectangular frame 32 and the drying box 21.

[0062] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, the sealing plate 41 seals the discharge pipe 27, the first connecting pipe 43 is connected to the external air supply equipment, and the first rubber inflatable ring 42 is inflated through the first connecting pipe 43 to expand it, thereby improving the sealing between the sealing plate 41 and the discharge pipe 27. The first fixed pipe 44 is used to support the first connecting pipe 43 to prevent the first connecting pipe 43 from being entangled when the sealing plate 41 moves up and down. The sealing plate 41 seals the discharge pipe 27 on the lower side of the drying box 21. The sealing plate 41 and the drying box 21 have the same curvature, so that raw materials will not accumulate in the discharge pipe 27, which is conducive to the overall uniform drying of the raw materials and avoids the situation where a small part of the raw materials has a poor drying effect at the beginning of discharging.

The limiting rod 45 limits the up and down movement of the sealing plate 41. When the sealing plate 41 moves downward to a preset position, the first rubber inflatable ring 42 is inflated for sealing. The dried raw materials fall from the discharge pipe 27 to the side tube 47, and the raw materials are collected from the two side tubes 47.
