Description

Technical Field

[0001] This utility model relates to the field of zinc oxide powder processing technology, and in particular to a zinc oxide powder drying device. Background Technology

[0002] Zinc oxide, commonly known as zinc white, is an oxide of zinc. It is sparingly soluble in water but soluble in acids and strong alkalis. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, coatings, ointments, adhesives, food, batteries, flame retardants, and other products. However, traditional drying equipment often results in zinc oxide powder with a certain level of moisture and clumping together, leading to poor drying efficiency. Furthermore, as a chemical additive, the gases produced during the drying process can disperse and potentially harm the health of workers.

[0003] Existing drying devices generally use a stirring device to assist hot air drying. However, the stirring device has difficulty solving the problem of zinc oxide agglomeration, resulting in uneven drying. In view of the above problems, this utility model provides a solution. Utility Model Content

[0004] The purpose of this invention is to provide a zinc oxide powder drying device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A zinc oxide powder drying device includes a base, a shell, a drying chamber, a feed inlet, and a discharge outlet. A cap is fitted over the feed inlet, and a plug is inserted into the discharge outlet. Two feeding rollers and a feeding belt are installed inside the drying chamber. The feeding rollers are connected to a motor outside the shell. The two feeding rollers are staggered, one above the other, causing the feeding belt to feed at an angle. Several evenly distributed shovels are fixedly installed on the feeding belt. A collection chamber is located at the lowest point of the drying chamber. When the shovels move to the bottom of the collection chamber with the feeding belt, the shovels... The tip of the material is attached to the bottom of the material collection chamber. The discharge port is located at the bottom of the extrusion chamber. A material distribution shaft is located below the upper feeding roller. The material distribution shaft is equipped with evenly distributed material distribution plates. The material distribution shaft is connected to an externally mounted motor. A fan and a resistance wire are provided on the outer shell. The resistance wire is located near the inner side of the drying chamber. The fan and the material distribution shaft are at the same horizontal position. An exhaust port is provided at the top of the drying chamber. A filter screen, a filter pad, and a filter material are installed in the exhaust port from bottom to top to filter the exhaust gas in sequence to meet emission standards.

[0007] Furthermore, the upper end of the plug cap forms an arc-shaped structure with the bottom cavity of the collection material, which fits in close contact with the tip of the shovel hopper. This structural design prevents the material in the bottom cavity from being scraped clean and thus from being insufficiently dried.

[0008] Furthermore, the bottom of the drying chamber is also provided with an inclined sliding plate, which is tangential to the arc structure of the bottom cavity of the collection chamber. The sliding plate is designed to guide the zinc oxide powder to the bottom cavity of the collection chamber, so that it can be circulated and dried by the shovel hopper.

[0009] Furthermore, the filter material is selected from quartz sand, or porous ceramics, activated carbon and other filter materials may be selected as needed.

[0010] Furthermore, the filter screen is made of metal wire; the filter pad is made of cotton and linen fabric.

[0011] In summary, the present invention has the following beneficial effects: The present invention uses a circulating throwing mechanism composed of a feeding roller, a feeding belt and a shovel hopper to throw zinc oxide material from the bottom of the device, and then the material is dispersed by the rotating material distribution shaft. After being dispersed, the material comes into contact with the hot air blown in by the fan, thereby achieving the purpose of uniform drying and avoiding the situation of uneven drying due to material accumulation.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] like Figure 1 and Figure 2As shown, a zinc oxide powder drying device includes a base 1, a shell 2, a drying chamber 3, a feed inlet 4, and a discharge outlet. A cap 5 covers the feed inlet 4, and a plug 6 is inserted into the discharge outlet. Two feeding rollers 7 and a feeding belt 8 installed between the two feeding rollers 7 are installed inside the drying chamber 3. The feeding rollers 7 are connected to a motor outside the shell 2. The two feeding rollers 7 are staggered, one above the other, so that the feeding belt 8 feeds material at an angle. Several evenly distributed shovels 9 are fixedly installed on the feeding belt 8. A collection chamber 10 is located at the lowest point of the bottom of the drying chamber 3. When the shovels 9 move to the bottom of the collection chamber 10 with the feeding belt 8, the tips of the shovels 9... The discharge port is located at the bottom of the extrusion chamber 10 and is fitted to the bottom of the material collection chamber 10. Below the upper feeding roller 7, there is a material distribution shaft 15. The material distribution shaft 15 is equipped with evenly distributed material distribution plates. The material distribution shaft 15 is connected to an externally mounted motor. The outer shell 2 is equipped with a fan 12 and a resistance wire 13. The resistance wire 13 is located near the inner side of the drying chamber 3. The fan 12 and the material distribution shaft 15 are at the same horizontal position. The top of the drying chamber 3 is equipped with an exhaust port 14. The exhaust port 14 is equipped with a filter screen 16, a filter pad 17 and a filter material 18 installed from bottom to top to filter the exhaust gas in sequence to meet the emission standards.

[0017] Furthermore, the upper end of the plug 6 forms an arc-shaped structure with the bottom cavity of the collection chamber 10, which fits against the tip of the shovel hopper 9. This structural design avoids the material in the bottom cavity of the collection chamber 10 not being scraped clean and thus not being dried sufficiently.

[0018] Furthermore, the bottom of the drying chamber 3 is also provided with an inclined sliding plate 11. The sliding plate 11 is tangent to the arc structure of the collecting bottom cavity 10. The structure of the sliding plate 11 is designed to guide the zinc oxide powder to the collecting bottom cavity 10, so that it can be circulated and dried with the shovel hopper 9.

[0020] Furthermore, the filter screen 16 is made of metal wire; the filter pad 17 is made of cotton and linen fabric.

[0021] Working principle: This utility model uses a circulating throwing mechanism composed of a feeding roller 7, a feeding belt 8 and a shovel 9 to throw zinc oxide material from the bottom of the device. The material is then dispersed by the rotating material distribution shaft 15. After being dispersed, the material comes into contact with the hot air blown in by the fan, thereby achieving uniform drying and avoiding uneven drying due to material accumulation.
