Description

Technical Field

[0001] This utility model relates to the field of polyester polyol production technology, and in particular to a feeding mechanism for polyester polyol production. Background Technology

[0002] The feeding mechanism for polyester polyol production is used to filter the raw materials used in the production of polyester polyol. However, general feeding mechanisms lack measures to handle and isolate the material, resulting in a large amount of material remaining in the filtration area of ​​the feeding mechanism, which reduces the feeding efficiency. The "Feeding Mechanism for Polyester Polyol Production" disclosed on the China Patent Network, with application number "202322062876.6", uses a rotating component to drive a rotating cylinder and an arc-shaped cylinder to rotate, which in turn drives the feeding hopper, feeding pipe, and threaded guide cylinder to rotate simultaneously. By feeding the material into the feeding hopper, the raw material enters the threaded guide cylinder through the feeding pipe. As the rotating cylinder drives the threaded guide cylinder to rotate, the raw material is subjected to centrifugal force from the threaded guide cylinder, thereby reducing the possibility of blockage in the feeding mechanism. However, the material is scattered by the centrifugal force of rotation, which increases the risk of material adhering to the inner wall of the feeding mechanism, thus increasing the difficulty of cleaning the feeding mechanism. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-6 This utility model provides a feeding mechanism for polyester polyol production, comprising: a housing 1, a sealing plate 13 on the upper surface of the housing 1, a feeding pipe 2 slidably connected to the surface of the sealing plate 13, a discharge pipe 4 and a discharge pipe 3 respectively provided inside the housing 1 and on the right surface, the discharge pipe 4 and the feeding pipe 2 being distributed vertically opposite each other and communicating with each other, the feeding pipe 2, the discharge pipe 4 and the discharge pipe 3 forming the material conveying structure of the feeding mechanism, two baffles 8 fixedly connected to the surface of the feeding pipe 2, the two baffles 8 being located on the upper and lower sides of the sealing plate 13 respectively, when the baffle 8 above the sealing plate 13 contacts the sealing plate 13, the lower end of the feeding pipe 2 contacts the upper surface of the filter plate 5, when the filter element is replaced, the baffle 8 below the sealing plate 13 engages with the sealing plate 13, the baffle 8 being used to limit the height of the feeding pipe 2.

[0025] Specifically, the material enters the interior of the housing 1 through the feeding pipe 2. Then, the feeding pipe 2 is pressed down so that it contacts the filter plate 5. The material then passes through the filter plate 5 and enters the interior of the discharge pipe 4. The material inside the discharge pipe 4 is discharged through the discharge pipe 3. When the filter plate 5 needs to be replaced, the feeding pipe 2 is lifted so that the baffle 8 below engages with the sealing plate 13, thereby moving the feeding pipe 2 away from the filter plate 5. The filter plate 5 can then be rotated and replaced.

[0026] The housing 1 is equipped with a servo motor 6 and a material box 7. The output end of the servo motor 6 is fixedly connected to a mounting rod 17. Both ends of the mounting rod 17 are fixedly connected to filter plates 5. When the feeding mechanism is used, the filter plates 5 at both ends of the mounting rod 17 are located directly above the discharge pipe 4 and the material box 7, respectively. The length and width of the discharge pipe 4 and the length and width of the material box 7 are both greater than the diameter of the filter plate 5. The diameter of the feeding pipe 2 is smaller than the diameter of the filter plate 5. The above components work together to form a rotating filter plate 5 replacement structure, which improves the convenience of handling filter plate 5 blockage.

[0027] Specifically, when using the feeding mechanism, the servo motor 6 drives the mounting rod 17 to rotate, and the filter plates 5 at both ends of the mounting rod 17 are moved to change position, thereby achieving the purpose of replacing the filter plate 5 below the feeding pipe 2.

[0028] An observation window 9 is snapped onto the surface of the sealing plate 13. A connecting rod 18 is fixedly connected to the lower surface of the observation window 9. The lower end of the connecting rod 18 is fixedly connected to the upper surface of the material box 7. A cleaning component 10 and two lifting parts 11 are provided on the surface of the observation window 9. The lower end of the cleaning component 10 penetrates through the sealing plate 13. The lifting parts 11 are fixedly connected to the left and right surfaces of the observation window 9. The lifting parts 11 consist of a side plate and a handle. The side plate is fixedly connected to the surface of the observation window 9, and the handle is fixedly connected to the upper surface of the side plate. The lifting parts 11 are connected to the connecting rod 18. The rod 18 improves the ease of handling the material box 7. The cleaning component 10 consists of a long rod 12, a brush 14, and a ball bearing 15. The brush 14 contacts the upper surface of the filter plate 5 above the material box 7. The lower end of the long rod 12 passes through the sealing plate 13 and is fixedly connected to the upper surface of the brush 14. The long rod 12 is fixedly connected to the inner shaft of the ball bearing 15. A spring 16 is fixedly connected to the upper surface of the inner shaft of the ball bearing 15. The upper end of the spring 16 is fixedly connected to the upper end of the long rod 12. The cleaning component 10 is used to improve the ease of cleaning the filter plate 5.

[0029] Specifically, when processing the filtered material, the observation window 9 is lifted using the lifting component 11. The observation window 9 drives the material box 7 to rise via the connecting rod 18, thereby removing the material box 7. When cleaning the material isolated on the upper surface of the filter plate 5, the long rod 12 is pressed down to make the brush 14 contact the filter plate 5. Then, the long rod 12 is rotated to use the brush 14 to clean the material isolated on the surface of the filter plate 5. The swept-off material falls directly into the interior of the material box 7.

[0030] Working principle: When it is found that too much material has accumulated on the filter plate 5 below the feeding pipe 2, the feeding pipe 2 is lifted, and then the servo motor 6 is used to rotate and replace the filter plate 5. At this time, the filter plate 5 that was originally opposite to the feeding pipe 2 is moved to the top of the material box 7. Then the feeding pipe 2 is pressed down to continue adding material. At the same time, the long rod 12 is pressed down to make the brush 14 contact the upper surface of the filter plate 5, and the long rod 12 is rotated to use the brush 14 to sweep off the material accumulated on the top of the filter plate 5. When it is necessary to collect the material, the servo motor 6 is used to rotate the filter plate 5 to a position away from the material box 7, and then the lifting part 11 is used to lift it up to remove the material box 7.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
