Description

Technical Field

[0001] This utility model belongs to the technical field of ultrafine powder preparation equipment, and in particular relates to a powder collector and pulverizing system with sterilization function. Background Technology

[0002] Air jet mills utilize high-pressure gas to drive high-speed collisions between materials, thereby achieving the purpose of pulverization. They are widely used in powder processing. Air jet mills mainly include an air jet mill chamber, a classifying impeller, a powder collector, and an induced draft fan.

[0003] The raw materials used in powder production, or those used during storage and transportation, can become contaminated with various bacteria. Some raw materials have numerous tiny grooves or crevices on their surfaces, which can easily harbor bacteria that are difficult to eliminate. Therefore, removing bacteria from raw materials before pulverization is challenging. The best approach is to sterilize the finished powder after pulverization. Therefore, the main objective of this application is to determine how to sterilize the powder during the collection process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a powder collector and pulverizing system with enhanced sterilization capabilities, which can sterilize the powder during the finished powder collection process to improve the quality of the finished powder product.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed:

[0006] A powder collector with sterilization function includes:

[0007] An upper chamber is located above the top plate of the shell, and a lower chamber is located below the bottom plate of the shell. A discharge pipe is located at the lower end of the lower chamber, and a feed pipe is located in the upper chamber. An air outlet pipe is connected to the side wall of the shell, and the end of the air outlet pipe is connected to the induced draft fan.

[0008] The filter tube has multiple tubes, with its two ends passing through the bottom plate and top plate of the shell respectively. The upper end of the filter tube is connected to the upper chamber, and the lower end of the filter tube is connected to the lower chamber.

[0009] The number of ultraviolet lamps is the same as that of the filter tubes, and they are inserted into the filter tubes one by one. The upper end of the ultraviolet lamp tube passes through the top of the upper chamber, and a power connector is provided at the top of the ultraviolet lamp tube.

[0010] The pulverizing system includes an air jet mill and the aforementioned powder collector with sterilization function, wherein the outlet of the air jet mill is connected to the feed pipe.

[0011] The beneficial effects of this invention are as follows: This solution utilizes the process of powder separation from airflow within the filter tube for sterilization via ultraviolet light, effectively ensuring that all finished materials pass through the sterilization area to guarantee the sterilization effect. Furthermore, the solution introduces the material into the filter tube while allowing airflow to exit from the outside, effectively confining the powder within a limited space, thus ensuring full contact between the ultraviolet light and the powder.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a powder collector with a better sterilization function includes: a shell 1, a filter tube 2 and a UV lamp tube 3.

[0024] An upper chamber 11 is provided above the top plate of the shell 1, and a lower chamber 12 is provided below the bottom plate of the shell 1. A discharge pipe 14 is provided at the lower end of the lower chamber 12, and a feed pipe 13 is provided in the upper chamber 11. An air outlet pipe 15 is provided on the side wall of the shell 1, and the end of the air outlet pipe 15 is connected to the induced draft fan 4.

[0025] The filter tube 2 has multiple tubes, with its two ends passing through the bottom plate and top plate of the housing 1 respectively. The upper end of the filter tube 2 is connected to the upper chamber 11, and the lower end of the filter tube 2 is connected to the lower chamber 12.

[0026] The number of ultraviolet lamps 3 is the same as that of filter tubes 2, and they are inserted into filter tubes 2 in a one-to-one correspondence. The upper end of the ultraviolet lamp 3 passes through the top of the upper chamber 11, and a power connector is provided at the top of the ultraviolet lamp 3.

[0027] The pulverized powder is automatically fed into the upper chamber 11 through the feed pipe 13 under the negative pressure airflow generated by the blower 4, and then automatically flows into the filter pipe 2 under the negative pressure airflow. After entering the filter pipe 2, the powder will either swirl and stop inside the filter pipe 2 under the negative pressure airflow, or flow downward along the filter pipe 2 and enter the lower chamber 12, and then enter the blower 4 through the discharge pipe 15. The negative pressure airflow is filtered through the filter pipe 2 and then enters the blower through the air outlet pipe 15. After entering the filter pipe 2, the powder enters the irradiation range of the ultraviolet lamp 3. The ultraviolet light generated by the ultraviolet lamp 3 is used to sterilize the powder, which can effectively sterilize the finished powder product to ensure the quality of the finished powder product.

[0028] Preferred, such as Figure 1 , Figure 2 As shown, the housing 1 is a cylindrical structure, and the filter tubes 2 are arranged in a circular array inside the housing 1 to ensure the balance of negative pressure airflow in all parts of the housing 1.

[0029] Preferably, the ultraviolet lamp tube 3 is coaxially arranged inside the filter tube 2 to ensure the uniformity of ultraviolet irradiation to all parts of the filter tube 2.

[0030] Preferred, such as Figure 3 As shown, a soft material ring 51 is coaxially fixed inside the filter tube 2. The ultraviolet lamp tube 3 passes through the ring 51, and the ring 51 is in contact with the outer wall of the ultraviolet lamp tube 3. The ultraviolet lamp tube 3 is vertically movable. Specifically, the ultraviolet lamp tube 3 can be moved by manually pulling the upper end of the ultraviolet lamp tube 3. When the ultraviolet lamp tube 3 moves up and down, it will move relative to the ring 51, thereby using the ring 51 to scrape off the dust attached to the surface of the ultraviolet lamp tube 3. By regularly cleaning the dust on the outside of the ultraviolet lamp tube 3, the irradiation brightness of the ultraviolet lamp tube 3 can be effectively guaranteed, and the sterilization effect of the ultraviolet lamp tube 3 can be prevented from being reduced due to dust adhesion. The ring 51 is made of nylon or plastic.

[0031] Preferred, such as Figure 2 , Figure 3 , Figure 4 As shown, a protective sleeve 31 is coaxially fitted on the outer side of the upper end of each ultraviolet lamp tube 3. The protective sleeve 31 passes through the top of the upper chamber 11, and a sealing structure is provided between the outer wall of the protective sleeve 31 and the mounting hole of the upper chamber 11. For example, a sealing ring is provided on the inner wall of the mounting hole to prevent powder leakage. The protective sleeve 31 is connected to the lower end of the same lifting rod 33 through a connecting plate 32. The lifting rod 33 is connected to the movable end of a lifting cylinder 34. With the above design, the lifting cylinder 34 can be used to simultaneously control all ultraviolet lamp tubes 3 to move in the vertical direction, thereby improving the automation level of the powder collector.

[0032] Preferred, such as Figure 3 , Figure 5As shown, the filter tube 2 has two parallel connecting rods 52 inside, and a ring 51 is connected between the two connecting rods 52. Multiple rings 51 are arranged in an array along the length of the connecting rods 52 and cover the length range of the ultraviolet lamp tube 3. This structural design can effectively reduce the movement stroke of the ultraviolet lamp tube 3. As long as the movement stroke of the ultraviolet lamp tube 3 is greater than or equal to the distance between the rings 51, the outer wall of the entire ultraviolet lamp tube 3 can be dusted.

[0033] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
