Description

Technical Field

[0001] This utility model relates to the field of industrial processing technology, specifically to a dryer for sodium methylparaben. Background Technology

[0002] Sodium methylparaben is a common chemical substance. It is a water-soluble alkaline preservative with safe, efficient, and broad-spectrum antibacterial properties, and is widely used in the preservation of cosmetics, pharmaceuticals, food, and other industrial products.

[0003] Sodium methylparaben requires drying to reduce its moisture content, improve its purity and stability, and prevent it from becoming damp or undergoing chemical reactions during storage and use. Furthermore, dried sodium methylparaben has better flowability, facilitating packaging, storage, and transportation while reducing the risk of moisture absorption by packaging materials.

[0004] In existing technologies, raw materials containing moisture tend to clump together before entering the drying oven. The clumps increase in volume, making them difficult to dry completely during subsequent drying processes. This results in slow moisture release and affects the drying effect, indicating room for technological improvement. Utility Model Content

[0005] This invention aims to solve the technical problem mentioned above, where the agglomerated raw materials become larger in volume and are difficult to dry completely during subsequent drying, by providing a sodium methylparaben dryer.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a dryer for sodium methylparaben, comprising a machine body, wherein a power assembly is provided on one side of the machine body; and further comprising:

[0007] Screening box; located above the machine body, the screening box is provided with a feed inlet, the screening box is provided with a filter plate, the filter plate is inclined; the area of ​​the pores on the filter plate can be adjusted; the screening box is provided with a discharge channel on the side near the lower end of the filter plate;

[0008] The crushing box is located on one side of the screening box and its upper end is connected to the discharge channel. The internal space of the crushing box is cylindrical, and the lower end is provided with a discharge port connected to the machine body. A filter plate is provided inside the discharge port. The crushing box is equipped with a crushing structure.

[0009] Furthermore, the discharge channel slopes downwards from the screening box to the crushing box.

[0010] Furthermore, the filter plate has several holes through it, the filter plate is hollow inside, and an adjustment plate is slidably provided. The adjustment plate has holes corresponding to the holes.

[0011] Furthermore, a support column is provided near one side of the adjustment plate, and a limiting groove is provided on the filter plate that can slide with the support column; a limiting plate is provided on the support column extending out of the limiting groove.

[0012] Furthermore, the screening box includes a box body and a cover body, the cover body is provided with a rectangular opening corresponding to the feed inlet; a lifting frame is provided below the screening box, and the lower end of the lifting frame is provided with a discharge port communicating with the machine body.

[0013] Furthermore, the crushing structure includes a motor located on the front of the crushing box, the output end of the motor extending into the crushing box and having a rotating shaft, and a plurality of fixing rings on the outside of the rotating shaft, each fixing ring having a symmetrical cutter on the outside, the cutters having different directions.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] Before entering the dryer, the raw materials are first screened. Powdered raw materials are directly fed into the machine body, while agglomerated raw materials are crushed by going through the inclined filter plate into the crushing box until their particle size is reduced to be able to pass through the second filter plate before entering the machine body again. This ensures that the raw materials entering the machine body are all crushed and free of agglomerates, thus improving the drying effect. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] Example 1, in conjunction with Appendix Figure 1 A dryer for sodium methylparaben includes a body 1, a power unit on one side of the body 1, and the body 1 is used to dry the raw material with hot air.

[0023] Combined with appendix Figure 1 , 2 It also includes a screening box 2; located above the machine body 1, the screening box 2 is provided with a feed inlet 3 for feeding; the screening box 2 is provided with a filter plate 4, which is inclined; the raw material is initially screened through the filter plate 4 to separate the agglomerated raw material, which is convenient for subsequent crushing;

[0024] The screening box 2 includes a box body and a cover 11. The cover 11 is provided with a rectangular opening corresponding to the feed inlet 3. The screening box 2 is provided with a lifting frame 12 below. The lower end of the lifting frame 12 is provided with a discharge port 2 that is connected to the machine body 1. The lifting frame 12 can raise the height of the screening box 2, so that the agglomerated raw materials can slide out by gravity.

[0025] Combined with appendix Figure 2 , 3 The area of ​​the pores on the filter plate 4 is adjustable. Specifically, the filter plate 4 has several holes 5 through it. The filter plate 4 is hollow inside and has an adjusting plate 6 that slides on it. The adjusting plate 6 has holes 7 that correspond to the holes 5. A support column 8 is provided on one side of the adjusting plate 6. The filter plate 4 has a limiting groove 9 that slides on the support column 8. The support column 8 extends out of the limiting groove 9 and has a limiting plate 10. In the above structure, by applying force to slide the limiting plate 10 and the support column 8, they move in the limiting groove 9, thereby moving the adjusting plate 6 inside the filter plate 4, adjusting the overlapping area of ​​the holes 5 and 7, thereby adjusting the aperture of the raw material falling through the hole, and determining the specific size of the agglomerates that need to be screened out.

[0026] Combined with appendix Figure 1 The screening box 2 is provided with a discharge channel 13 on the side near the lower end of the filter plate 4. The discharge channel 13 slopes downward from the screening box 2 to the crushing box 14, so that the agglomerated raw materials can slide into the crushing box 14.

[0027] Combined with appendix Figure 1 , 4 The crushing box 14 is located on one side of the screening box 2 and its upper end is connected to the discharge channel 13. The internal space of the crushing box 14 is cylindrical, which facilitates the operation of the crushing structure and reduces dead corners. The lower end of the crushing box 14 is provided with a discharge port 18 connected to the machine body 1. The discharge port 18 is provided with a second filter plate 19. The crushed raw material can be screened again through the second filter plate 19. The agglomerated raw material that is not completely crushed cannot enter the machine body 1 and continue to be crushed.

[0028] Based on the above structure, the crushing box 4 is equipped with a crushing structure, which includes a motor 15 located on the front of the crushing box 14. The output end of the motor 15 extends into the crushing box 14 and is equipped with a rotating shaft 16. Several fixing rings are provided on the outside of the rotating shaft 16. Symmetrical cutters 17 are provided on the outside of each fixing ring. The directions of the cutters 17 are different, which improves the crushing effect. This ensures that the raw materials entering the machine body 1 are not clumped, thereby improving the drying effect and uniformity.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
