Description

Technical Field

[0001] This utility model relates to the technical field of preheating devices, and more specifically, to a preheating device for polystyrene production. Background Technology

[0002] In existing technologies, the preheating devices used in polystyrene production cannot easily complete the crushing and collection process of polystyrene during use. This problem seriously restricts production efficiency. Specifically, when the debris and particles generated during the preheating process of polystyrene raw materials need to be recycled, the existing devices lack an effective collection mechanism, resulting in a large amount of valuable materials being wasted.

[0003] During use, the existing device cannot easily disconnect the fixed relationship between the collection box and the filter plate. When cleaning, maintenance or replacement of parts is required, the operator faces a cumbersome disassembly procedure.

[0004] Regarding the core components of the equipment, existing devices cannot easily complete the fixing process between the collection box and the filter plate during use. This technical problem mainly lies in the unreasonable design of the connection mechanism. Traditional fixing methods often use bolt connections or snap-fit ​​structures, which are prone to deformation or loosening under high temperature and high pressure working environments.

[0022] Please see Figures 1-6 A preheating device for polystyrene production includes a collection box 1, on which a crushing assembly is provided. The crushing assembly includes a filter plate 2 and a crushing chamber 3. The filter plate 2 is slidably connected to the collection box 1, and the crushing chamber 3 is disposed on the collection box 1. A drive shaft 4 is rotatably connected in the crushing chamber 3. Two drive shafts 4 are provided. A crushing blade 5 is installed on the drive shaft 4. A meshing gear 6 is connected to one end of the drive shaft 4. A splitting assembly is provided between the collection box 1 and the filter plate 2. The splitting assembly includes a fixing rod 7 and a fixing sleeve 8. The fixing rod 7 is fixedly installed on the collection box 1, and the fixing sleeve 8 is detachably disposed on one end of the fixing rod 7. One end of the fixing sleeve 8 is tightly attached to the filter plate 2, and a moving ring 9 is slidably connected to the fixing sleeve 8.

[0023] A first motor 17 is installed on the collection box 1. The output end of the first motor 17 is connected to a rotating shaft 10. A rotating blade 11 is installed on the rotating shaft 10. The rotating blade 11 is in close contact with one end of the filter plate 2.

[0024] A second motor 14 is installed on the collection box 1. The output end of the second motor 14 is connected to one of the drive shafts 4. An inclined bucket 15 is connected between the crushing box 3 and the collection box 1. A sliding box 16 is slidably connected to the bottom of the collection box 1. A placement cylinder 12 is installed in the sliding box 16. An electric heating wire 13 is sleeved on the outside of the placement cylinder 12.

[0025] A first spring 18 is provided between the moving ring 9 and the fixed sleeve 8, and a moving rod 19 is installed on the moving ring 9.

[0026] An abutment plate 20 is installed on the movable rod 19.

[0027] In this embodiment, material is injected into the crushing chamber 3. The second motor 14 is started, causing the drive shaft 4 at the output end to rotate, which in turn drives the meshing gear 6 to rotate, thereby rotating the crushing blade 5. This completes the crushing of the material. The crushed material falls along the inclined hopper 15 into the collection box 1. The first motor 17 is started, causing the rotating shaft 10 to rotate, which in turn rotates the rotating blade 11. This causes the material falling onto the filter plate 2 to be agitated. During this agitation, some of the material flows along the filter plate... The filter plate 2 falls into the placement cylinder 12 in the sliding box 16, and the material is preheated by the heating wire 13. Then the sliding box 16 is slid out along the collection box 1. When the filter plate 2 needs to be removed after a period of use, the moving ring 9 is slid off along the fixed sleeve 8. During the sliding movement, the first spring 18 is compressed. When the moving ring 9 moves, the moving rod 19 is moved, thereby removing one end of the moving rod 19 from the rotating ring 21 and releasing the fixing of the rotating ring 21.

[0028] Please see Figure 4-6 As an embodiment of a preheating device for polystyrene production with a fixed component: a fixed component is provided on the fixed sleeve 8. The fixed component includes a rotating ring 21 and a rotating sleeve 22. The rotating ring 21 is rotatably connected to the fixed sleeve 8, and the rotating sleeve 22 is connected to the rotating ring 21. An unlocking groove 23 is provided on the rotating sleeve 22.

[0029] A fixing plate 24 is installed on the fixing sleeve 8. A third spring 25 is connected between the fixing plate 24 and the rotating ring 21. One end of the moving rod 19 is inserted into the rotating ring 21. The abutting plate 20 is in close contact with the rotating ring 21. An abutting block 26 is slidably connected on the fixing sleeve 8.

[0030] A second spring 27 is provided between the abutment block 26 and the fixed sleeve 8. One end of the abutment block 26 is adapted to the unlocking groove 23. An insertion groove 28 is provided on the fixed rod 7, and the insertion groove 28 is adapted to the abutment block 26.

[0031] More specifically, the rotating ring 21 is then rotated along the fixed sleeve 8. During rotation, the third spring 25 between the rotating ring 21 and the fixed plate 24 is compressed. As the rotating ring 21 rotates, the rotating sleeve 22 at one end of the rotating ring 21 rotates. During rotation, the unlocking groove 23 is moved, so that the unlocking groove 23 abuts the abutting block 26, thereby causing the abutting block 26 to slide along the fixed sleeve 8. During the movement, the second spring 27 between the abutting block 26 and the fixed sleeve 8 is stretched, so that one end of the abutting block 26 is removed from the insertion groove 28 of the fixed rod 7, thereby releasing the fixation of the fixed rod 7. Then, the fixed sleeve 8 is slid out along the fixed rod 7, and the filter plate 2 can be removed from the fixed rod 7 for cleaning or replacement.

[0032] In summary, during the use or operation of the entire equipment: material is injected into the crushing chamber 3. Starting the second motor 14 rotates the drive shaft 4 at the output end, which in turn rotates the meshing gear 6, thereby rotating the crushing blades 5, thus crushing the material. The crushed material falls along the inclined hopper 15 into the collection box 1. Starting the first motor 17 rotates the rotating shaft 10, which in turn rotates the rotating blades 11, causing the material falling onto the filter plate 2 to be agitated. During this agitation, some of the material... The material falls along the filter plate 2 into the placement cylinder 12 in the sliding box 16, and is preheated by the heating wire 13. Then, the sliding box 16 is slid out along the collection box 1. After the filter plate 2 has been used for a period of time, when it needs to be removed, the moving ring 9 is slid off along the fixed sleeve 8. During the sliding movement, the first spring 18 is compressed. When the moving ring 9 moves, the moving rod 19 is moved, thereby removing one end of the moving rod 19 from the rotating ring 21 and releasing the fixing of the rotating ring 21.

[0033] Next, the rotating ring 21 is rotated along the fixed sleeve 8. During rotation, the third spring 25 between the rotating ring 21 and the fixed plate 24 is compressed. As the rotating ring 21 rotates, the rotating sleeve 22 at one end of the rotating ring 21 is also rotated. During rotation, the unlocking groove 23 is moved, so that the unlocking groove 23 abuts the abutting block 26, thereby causing the abutting block 26 to slide along the fixed sleeve 8. During the movement, the second spring 27 between the abutting block 26 and the fixed sleeve 8 is stretched, so that one end of the abutting block 26 is removed from the insertion groove 28 of the fixed rod 7, thereby releasing the fixation of the fixed rod 7. Then, the fixed sleeve 8 is slid out along the fixed rod 7, and the filter plate 2 can be removed from the fixed rod 7 for cleaning or replacement.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
