Abstract
Description
Technical Field
[0001] The present application relates to the field of material spreading devices, and in particular to a material spreading device for a chain plate dryer. Background Art
[0002] Super absorbent polymer (SAP) is a new type of functional polymer material with strong water absorption and water retention. Super absorbent polymers contain strong hydrophilic groups and have a certain degree of cross-linking. They are insoluble in water and organic solvents, can absorb hundreds to thousands of times their own weight in water, and can retain moisture even under pressure. Super absorbent polymers play an important role in many fields due to their unique physical and chemical properties, and their application range is constantly expanding with the development of science and technology.
[0003] After the polymerization reaction, the polymer gel is crushed and granulated to form gel particles with a size of about 10-20mm. The moisture content of the gel particles is about 50-60%, and the gel particles need to be dried. The chain plate dryer is the most commonly used drying equipment in the production process of super absorbent resin. However, since the gel particles after granulation are very sticky and the width of the dryer chain is also wide, a suitable material spreading mechanism is required to evenly distribute the particles on the chain plate.
[0004] In the related art, a swing spreading mechanism is usually used to achieve this. The unloading end of the spreading mechanism swings back and forth above the chain plate under the drive of a hydraulic cylinder or a servo motor to spread the material evenly on the chain plate. In actual use, the middle of the chain plate can basically ensure uniform spreading of the material, but the two sides of the chain plate are prone to local accumulation of materials, affecting the flatness and uniformity of the material distribution. Utility Model Content

[0009] By adopting the above technical solution, when materials accumulate on both sides of the chain plate, as the chain plate is conveyed, the accumulated materials are transported to the bottom of the installation shaft, and the toggle member will toggle the materials that exceed the laying height toward the incoming material direction, so that the materials on both sides of the chain plate are maintained at the preset laying height, thereby improving the uniformity of material distribution on the rear chain plate, improving the drying effect and drying efficiency of the materials, and avoiding the materials accumulated on both sides of the chain plate from being unable to be dried normally.
[0010] Optionally, the toggle member includes a toggle rod, which is radially arranged along the installation axis. When the toggle rod is vertically facing the chain plate, the distance between the end of the toggle rod and the chain plate is the laying height of the material.

[0033] The following is combined with Figure 1-3 This application is described in further detail.
[0034] Embodiment 1:
[0035] Embodiment 1 of the present application discloses a material spreading device for a chain plate type dryer, referring to Figure 1 and Figure 2 , including a swing auxiliary machine 1, a connecting shaft 2 and a toggle member 3. The swing auxiliary machine 1 is arranged on one side of the dryer, and the unloading port of the swing auxiliary machine 1 faces the chain plate 01 of the dryer. The two ends of the connecting shaft 2 are coaxially fixed with mounting shafts 4. The ends of the two mounting shafts 4 that are away from each other are rotatably mounted on the frame of the dryer, and are connected to a driving mechanism that drives the mounting shafts 4 to rotate. The two mounting shafts 4 are respectively located above the two side edges of the chain plate 01, and the axis of the mounting shaft 4 is perpendicular to the feeding direction. A plurality of toggle members 3 are arranged and fixed on the side of the mounting shaft 4. The minimum spacing between the toggle member 3 and the chain plate 01 is the laying height of the material.
[0036] During specific operation, the driving mechanism drives the installation shaft 4 to rotate, and the toggle member 3 fixed on the side of the installation shaft 4 rotates around the axis of the installation shaft 4. When materials are accumulated on both sides of the chain plate 01, as the chain plate 01 is conveyed, the accumulated materials are transported to the bottom of the installation shaft 4, and the toggle member 3 toggles the materials exceeding the laying height in the direction of the incoming materials, so that the materials on both sides of the chain plate 01 are maintained at the preset laying height, thereby improving the uniformity of material distribution on the rear chain plate 01, improving the drying effect and drying efficiency of the materials, and avoiding the materials accumulated on both sides of the chain plate 01 from being unable to be dried normally.
[0037] Specifically, refer to Figure 1 and Figure 2 The toggle member 3 is configured as a toggle rod 31, which is a cylindrical rod structure, and is used to directly contact the material that exceeds the laying height and to push the material in the direction of the incoming material to ensure the uniformity of the material distribution at the rear. In other embodiments, the toggle rod 31 can also be configured as a rod with a rectangular or triangular cross-section; in addition, the toggle rod 31 can also be configured as a plate, but since the plate has a certain wind resistance when rotating, it is preferably a rod in this embodiment, which can achieve faster rotation.
[0038] Further, refer to Figure 1 and Figure 2The toggle rod 31 is arranged along the radial direction of the mounting shaft 4. The minimum distance between the toggle rod 31 and the chain plate 01 is the distance between the end of the toggle rod 31 and the chain plate 01 when the toggle rod 31 is perpendicular to the chain plate 01. The distance is the same as the laying height of the material. When the mounting shaft 4 rotates, the toggle rod 31 rotates synchronously, and its end can push away the material that exceeds the laying height, thereby improving the uniformity of material distribution.
[0039] Preferably, a plurality of toggle rods 31 are evenly distributed around the mounting shaft 4. This structure can effectively improve the effect of the toggle rods 31 in separating materials.
[0040] Further, refer to Figure 1 and Figure 2 , the toggle rods 31 are configured into multiple groups, each group includes two toggle rods 31, and the two toggle rods 31 in the same group are coaxially arranged, and the toggle rods 31 in each group are distributed at equal intervals. In other embodiments, each group of toggle rods 31 can also be configured with other numbers, for example, each group includes four toggle rods 31, and each group of four toggle rods 31 is distributed in a cross shape. By arranging the toggle rods 31 regularly, it is possible to achieve a better effect of separating materials when fewer toggle rods 31 are set, thereby improving the efficiency of separating materials.
[0041] Further, refer to Figure 1 and Figure 2 , from both sides of the chain plate 01 to the direction close to the center of the chain plate 01, the axes of each group of toggle rods 31 are staggered at a fixed angle in sequence, and the toggle rods 31 are distributed in a spiral shape along the axis direction of the installation shaft 4. The spiral distribution makes it easier for the installation shaft 4 and the toggle rods 31 to rotate at a high speed, so as to achieve a better toggle effect and avoid missing some accumulated materials due to insufficient rotation speed.
[0042] In this embodiment, the axis difference between two adjacent groups of toggle rods 31 is preferably 20 degrees. In other embodiments, it can be set to other angles according to actual needs.
[0043] Preferably, the spacing between two adjacent groups of toggle rods 31 is 150-250 mm, preferably 200 mm in this embodiment. Appropriate spacing can meet the need of toggle materials, while not affecting the high-speed rotation of the mounting shaft 4 and the toggle rod 31.
[0044] The implementation principle of Example 1 of the present application is: as the installation shaft 4 rotates, the toggle rod 31 continuously separates the material exceeding the laying height to the incoming direction, ensuring that the material on the chain plate 01 is evenly distributed, thereby improving the drying effect and efficiency.
[0045] Embodiment 2:
[0046] The difference between this embodiment and embodiment 1 is that:
[0047] Reference Figure 3A chain plate type dryer paving device also includes a mounting frame 5, which is fixed to the dryer and located above the chain plate 01. Two mounting shafts 4 are rotatably arranged on the mounting frame 5 and are respectively connected to driving mechanisms. The two mounting shafts 4 are arranged in a V-shaped structure, and the opening of the V-shaped structure faces the swing auxiliary machine 1, that is, towards the incoming direction.
[0048] When the two mounting shafts 4 rotate, the toggle member 3 is driven to rotate around the axis of the mounting shaft 4, and the material exceeding the laying height is pushed back to the incoming direction. Since materials are easily accumulated on both sides of the chain plate 01, the materials are pushed away along the feeding direction, and the materials will accumulate on both sides of the chain plate 01 in the incoming direction. By setting the mounting shaft 4 to a V-shaped structure, the toggle member 3 pushes the material toward the middle of the chain plate 01 to avoid continuous accumulation of materials on both sides.
[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
