[0002] In the field of catalyst production equipment technology, the feeding process of light powder is a key link. However, traditional feeding devices have some problems when handling light powder. Due to the fine particles and light weight of light powder, it is easy to generate a lot of dust during the feeding process, which not only affects the working environment, but also may threaten the health of operators.

[0003] In addition, traditional feeding devices often fail to achieve uniform mixing of powder materials during the feeding process, resulting in unstable quality in the subsequent production process. At the same time, flying dust may also clog the equipment, affecting the normal operation of the equipment and increasing maintenance costs. In view of this, we propose a gas internal circulation device for feeding light powder materials. Utility Model Content

[0024] A gas internal circulation device for feeding light powder materials comprises a feeding funnel 1 and a filling funnel 2 plugged into the top of the feeding funnel 1, a feeding tube 3 is integrally formed at the bottom of the feeding funnel 1, a gas riser 5 for connecting the feeding funnel 3 to the feeding funnel 1 is provided on the outer side of the feed tube 3, an air pump 6 is installed on the gas riser 5, an annular support net 10 is provided on the top of the feeding funnel 1, an extension tube 50 is integrally formed at one end of the gas riser 5 located in the feeding funnel 1, a movable tube 51 is rotatably installed on the inner wall of one end of the extension tube 50 away from the gas riser 5 through a bearing 52, at least one turbine blade 53 is fixedly installed on the inner wall of the movable tube 51, and a plurality of evenly distributed air outlet holes 510 are opened on the circumferential outer wall of the movable tube 51. By setting up an air pump 6, the gas in the delivery funnel 1 moves downward, which can accelerate the sedimentation of the gas in the delivery funnel 1. At the same time, a movable tube 51 that can rotate under the drive of a turbine blade 53 is set. The movable tube 51 rotates simultaneously during the process of the gas in the movable tube 51 being discharged from the air outlet 510, which can mix the dust raw materials added to the delivery funnel 1 and improve the mixing effect when the dust raw materials are added.

[0025] As a preferred embodiment of the present invention, a support block 11 for supporting the sub-packaging funnel 2 is welded at the top center of the delivery funnel 1, and a feeding pipe 21 at the bottom of the sub-packaging funnel 2 passes through the support block 11 respectively. A through hole for the feeding pipe 21 to pass through is provided at the top of the delivery funnel 1, and a solenoid valve 22 is installed on the feeding pipe 21. The support block 11 is arranged at the top center of the delivery funnel 1 to provide a stable support for the sub-packaging funnel 2. The design of the feeding pipe 21 enables the powder to smoothly enter the delivery funnel 1 from the sub-packaging funnel 2, and the solenoid valve 22 can effectively control the flow of the powder to achieve quantitative delivery.

[0026] As a preferred embodiment of the present invention, a baffle 12 is hingedly installed at one side of the perforation at the bottom of the delivery funnel 1, and a torsion spring is installed between the baffle 12 and the bottom of the delivery funnel 1. The perforation of the delivery funnel 1 can be conveniently opened or closed by the hinged baffle 12, so as to facilitate the installation or removal of the dispensing funnel 2. The design of the torsion spring enables the baffle 12 to automatically reset when no external force is required, thereby improving the convenience of use.

[0027] As a preferred embodiment of the present invention, a feeding cover 20 is hingedly mounted on the top of the dispensing funnel 2, and a handle is mounted on the feeding cover 20. The feeding cover 20 hingedly mounted on the top of the dispensing funnel 2 can prevent the powder from being damp or contaminated during storage.

[0028] As a preferred embodiment of the present invention, a blocking net 33 is installed at the pipe opening at one end where the gas riser 5 is connected to the material discharge pipe 3. The blocking net 33 installed at the connection between the gas riser 5 and the material discharge pipe 3 can effectively prevent the powder from entering the gas riser 5, thereby ensuring the normal operation of the air pump 6 and the smooth circulation of the gas.

[0029] As a preferred embodiment of this embodiment, a cleaning mechanism for cleaning the blocking net 33 is installed inside the feeding tube 3. The cleaning mechanism includes a fixed block 30 fixedly connected to the inner wall of the feeding tube 3, a scraper 32 is provided below the fixed block 30, and an electric telescopic rod 31 for driving the scraper 32 to move up and down is installed on the fixed block 30. Through the cleaning mechanism installed inside the feeding tube 3, the blocking net 33 can be cleaned regularly to prevent powder from clogging the mesh. The design of the electric telescopic rod 31 and the scraper 32 makes the cleaning process automatic and improves work efficiency.

[0030] As a preferred embodiment of the present invention, when the piston rod of the electric telescopic rod 31 is extended to the longest, the scraper 32 moves to the bottom of the blocking net 33. This ensures effective cleaning of the blocking net 33 and avoids the residue of powder.

[0031] As a preferred embodiment of the present invention, a mounting plate 4 is fixedly connected to the bottom of the feed pipe 3, and a mounting hole is provided at each of the four corners of the mounting plate 4. The mounting plate 4 and the mounting hole design at the bottom of the feed pipe 3 enable the entire device to be conveniently installed in various working environments, thereby improving the applicability and flexibility of the device.

[0032] When the utility model's light powder feeding gas internal circulation device is used:

[0033] First, the user opens the feeding cover 20 on the top of the dispensing funnel 2 and adds the powdery raw material into the dispensing funnel 2. Then, by controlling the opening and closing of the solenoid valve 22, the powdery raw material can be quantitatively fed from the dispensing funnel 2 to the feeding funnel 1 through the feeding pipe 21.

[0034] During the delivery process, the air pump 6 starts to work, sucks in external air through the gas riser 5 and pumps it into the extension tube 50. The gas in the extension tube 50 then enters the movable tube 51, and pushes the turbine blades 53 to make the movable tube 51 start to rotate. When the gas is discharged through the gas outlet 510 of the movable tube 51, due to the rotation of the movable tube 51, the discharged gas can act more evenly on the powdery raw material, which is conducive to the uniform dispersion of the gas and can also promote the full mixing of the powdery raw material in the delivery funnel 1.

[0035] Due to the arrangement of the support net 10 in the delivery funnel 1, the gas flow direction is still downward, which accelerates the settling of dust in the delivery funnel 1 and effectively reduces the flying of dust.

[0036] During the discharge of the powdery raw materials through the discharge pipe 3 , part of the powdery raw materials may be blocked by the blocking net 33 to ensure that they do not enter the gas riser 5 , thereby ensuring the normal operation of the air pump 6 and the smooth circulation of the gas.

[0037] As time goes by, a certain amount of powdery raw materials may accumulate on the blocking net 33. At this time, the blocking net 33 can be regularly cleaned by controlling the extension and retraction of the electric telescopic rod 31 to drive the scraper 32 to move up and down, so as to prevent the powdery raw materials from clogging the mesh and ensure the continuous and effective operation of the device.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
