Description

Technical Field

[0001] This utility model relates to the field of green mud processing technology, specifically to a papermaking green mud drying device that prevents clumping. Background Technology

[0002] Papermaking green mud is a solid waste generated during the pulping and papermaking processes in the paper industry, primarily originating from the alkali recovery stage of the papermaking process. In alkaline pulping, chemicals such as sodium hydroxide are used to cook wood or other fiber raw materials to remove impurities like lignin, allowing the fibers to separate for papermaking. During this process, some inorganic mineral components in the raw materials (such as compounds of silicon, calcium, magnesium, and aluminum) circulate in the system along with the cooking liquor. When the cooking liquor undergoes alkali recovery treatment, these inorganic components gradually accumulate and form precipitates, which constitute papermaking green mud. For example, silica in the raw materials reacts with alkali during cooking to form compounds such as sodium silicate, which, in subsequent treatment steps, becomes part of the green mud due to changes in chemical equilibrium and physical precipitation.

[0003] These green muds can be recycled and processed to produce building materials. However, these papermaking green muds tend to clump together when dried. Green muds often need to be in powder or granule form to facilitate subsequent processing and utilization. Therefore, it is necessary to prevent the green muds from clumping due to loss of moisture during the drying process.

[0004] To address this problem, this invention provides a papermaking green mud drying device that prevents clumping. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a papermaking green mud drying device that prevents clumping, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a papermaking green mud drying device for preventing caking, comprising a protective cover, an anti-caking component on the top of the protective cover, and a movable component on the bottom of the protective cover; the anti-caking component includes a mounting base, a placement box inserted into the top of the mounting base, a support rod fixedly connected to the top of the protective cover, a top plate fixedly connected to one end of the support rod, a central rod rotatably connected inside the top plate, an assembly plate fixedly connected to one end of the central rod, the anti-caking component further comprising a rotating roller, one end of the rotating roller rotatably connected inside the assembly plate, crushing teeth fixedly connected to the outer wall of the rotating roller, concave blocks fixedly connected to the inner wall of the protective cover, and heating rods fixedly installed between the inner walls of the concave blocks.

[0007] Furthermore, a first servo motor is fixedly installed on the top of the top plate, and the output shaft of the first servo motor is fixedly connected to one end of the center rod.

[0008] The above technical solution is used to provide power to drive the center rod to rotate.

[0009] Furthermore, the outer wall of the protective cover is fixedly connected to a protrusion, and the anti-caking assembly also includes a protective cylinder. A hydraulic rod is fixedly installed inside the protective cylinder, and the movable end of the hydraulic rod is fixedly connected to the bottom of the protrusion.

[0010] The above-mentioned technical solution is used to lift the protective cover upwards.

[0011] Furthermore, the movable component includes a nut block, which is fixedly connected to the bottom of the mounting base, and rollers are rotatably connected between the inner walls of the nut block.

[0012] The above technical solution is used to support the mounting base and enable it to move.

[0013] Furthermore, an auxiliary block is fixedly connected to the bottom of the mounting base, and the moving component also includes a protective plate. A limit rod is fixedly connected between the two protective plates, and the limit rod is slidably connected to the inside of the auxiliary block.

[0014] The above technical solution is used to make the mounting base more stable when it is moved.

[0015] Furthermore, a lead screw is rotatably connected between the two guard plates. The lead screw is internally threaded to the nut block. A second servo motor is fixedly installed on one side of the guard plate, and the output shaft of the second servo motor is fixedly connected to one end of the lead screw.

[0016] By adopting the above technical solution, power is provided to drive the lead screw to rotate, ultimately causing the nut block to move.

[0017] Beneficial effects

[0018] This invention provides a papermaking green mud drying device to prevent clumping. Compared with the prior art, it has the following advantages:

[0019] 1. The papermaking green mud drying device for preventing clumping first puts the green mud into the placement box, then starts the second servo motor to drive the lead screw to rotate. After the lead screw rotates, under the restriction of the limit rod and the auxiliary block, it will cause the nut block to drive the mounting base to move to one side until it moves to the bottom of the protective cover. The bottom of the placement box is connected to the mounting base through a rectangular plug to facilitate quick disassembly of the placement box for replacement and cleaning.

[0020] 2. In this anti-caking papermaking green mud drying device, after the placement box is moved below the protective cover, the hydraulic rod is activated to lower the protective cover, which then surrounds the entire placement box. The heating rod can then be turned on to generate heat, raising the temperature inside the protective cover to dry the green mud. After that, the first servo motor is activated, which in turn drives the central rod to rotate. The central rod then drives the assembly plate to rotate, and the rotation of the assembly plate causes the rotating roller to rotate accordingly. When the rotating roller comes into contact with the green mud, it will also rotate due to friction. In this way, the crushing teeth on the outer wall of the rotating roller will repeatedly crush the surface of the green mud to prevent it from clumping, so that it can eventually form powder or granules.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4 This application provides an anti-caking papermaking green mud drying device, including a protective cover 1. An anti-caking component 2 is disposed on the top of the protective cover 1, and a movable component 3 is disposed on the bottom of the protective cover 1. The anti-caking component 2 includes a mounting base 21, with a placement box 22 inserted into the top of the mounting base 21. A support rod 23 is fixedly connected to the top of the protective cover 1, and a top plate 24 is fixedly connected to one end of the support rod 23. A central rod 26 is rotatably connected inside the top plate 24, and an assembly plate 27 is fixedly connected to one end of the central rod 26. The anti-caking component 2 also includes a rotating roller 28, one end of which is rotatably connected to the inside of the assembly plate 27. Crushing teeth 29 are fixedly connected to the outer wall of the rotating roller 28. Concave blocks 213 are fixedly connected to the inner wall of the protective cover 1, and heating rods 214 are fixedly installed between the inner walls of the concave blocks 213. A first servo motor 25 is fixedly installed on the top of the top plate 24, and the output shaft of the first servo motor 25 is fixedly connected to one end of the central rod 26. The outer wall of the protective cover 1 is fixedly connected with a protrusion 212. The anti-caking component 2 also includes a protective cylinder 210. A hydraulic rod 211 is fixedly installed inside the protective cylinder 210. The movable end of the hydraulic rod 211 is fixedly connected to the bottom of the protrusion 212.

[0030] In specific implementation: After the placement box 22 moves below the protective cover 1, the hydraulic rod 211 is activated to drive the protective cover 1 to descend, and the protective cover 1 surrounds the entire placement box 22. Then, the heating rod 214 can be turned on to generate heat, raising the temperature inside the protective cover 1 to dry the green mud. Then, the first servo motor 25 is activated, which drives the central rod 26 to rotate. The central rod 26 drives the assembly plate 27 to rotate, and the rotation of the assembly plate 27 causes the rotating roller 28 to rotate as well. When the rotating roller 28 comes into contact with the green mud, it will also rotate due to friction. In this way, the crushing teeth 29 on the outer wall of the rotating roller 28 will repeatedly crush the surface of the green mud to prevent it from clumping, so that it can eventually form powder or granules.

[0031] Reference Figures 1 to 4 In one aspect of this embodiment, the moving component 3 includes a nut block 35, which is fixedly connected to the bottom of the mounting base 21. Rollers 36 are rotatably connected between the inner walls of the nut block 35. An auxiliary block 32 is fixedly connected to the bottom of the mounting base 21. The moving component 3 also includes guard plates 31, with a limit rod 33 fixedly connected between the two guard plates 31. The limit rod 33 is slidably connected to the interior of the auxiliary block 32. A lead screw 34 is also rotatably connected between the two guard plates 31, and the lead screw 34 is threadedly connected to the interior of the nut block 35. A second servo motor 37 is fixedly mounted on one side of the guard plate 31, and the output shaft of the second servo motor 37 is fixedly connected to one end of the lead screw 34.

[0032] In practice: First, put the green mud into the placement box 22, then start the second servo motor 37 to drive the lead screw 34 to rotate. After the lead screw 34 rotates, under the restriction of the limit rod 33 and the auxiliary block 32, it will cause the nut block 35 to drive the mounting base 21 to move to one side until it moves directly under the protective cover 1. The bottom of the placement box 22 is connected to the mounting base 21 through a rectangular plug to facilitate quick disassembly of the placement box 22 for replacement and cleaning.

[0033] All electrical devices in this plan are powered by an external power source.

[0034] Working principle: First, the green mud is placed into the placement box 22. Then, the second servo motor 37 is started, which drives the lead screw 34 to rotate. After the lead screw 34 rotates, under the constraint of the limit rod 33 and the auxiliary block 32, it will cause the nut block 35 to move the mounting base 21 to one side until it moves directly under the protective cover 1. The bottom of the placement box 22 is connected to the mounting base 21 through a rectangular insert for easy disassembly of the placement box 22 for replacement and cleaning. When the placement box 22 moves under the protective cover 1, the hydraulic rod 211 is started, which drives the protective cover 1 to descend. The protective cover 1 covers the entire placement box 22. 2. After surrounding the mud, the heating rod 214 can be turned on to generate heat, raising the temperature inside the protective cover 1 to dry the green mud. Then, the first servo motor 25 is started, which in turn drives the central rod 26 to rotate. The central rod 26 in turn drives the assembly plate 27 to rotate, and the rotation of the assembly plate 27 causes the rotating roller 28 to rotate as well. When the rotating roller 28 comes into contact with the green mud, it will also rotate due to friction. In this way, the crushing teeth 29 on the outer wall of the rotating roller 28 will repeatedly crush the surface of the green mud to prevent it from clumping, so that it can eventually form powder or granules.
