Detailed Implementation

[0022] like Figures 1 to 6 As shown, this utility model relates to a feeding and lifting device for ferrotitanium powder raw materials, including a conveying pipe 101 and a feeding mechanism 200 and a diameter-changing mechanism 300 installed on the conveying pipe 101. A conveying fan 102 is installed at the beginning of the conveying pipe 101, and a lifting pipe 103 is installed at the end of the conveying pipe 101. The diameter-changing mechanism 300 includes an adjustable diameter pipe 301 and a discharge pipe 303. The adjustable diameter pipe 301 includes an array of arc-shaped plates 3011. The lower part of the arc-shaped plates 3011 is rotatably connected to the inner wall of the lifting pipe 103. An electric push rod 302 is installed on the upper part of the outer surface of the lifting pipe 103. The piston rod of the electric push rod 302 is connected to the upper part of the arc-shaped plates 3011. The discharge pipe 303 is installed at the upper end of the lifting pipe 103. This utility model has an adjustable diameter pipe structure, which can effectively increase the airflow speed, enhance the carrying capacity of materials, effectively overcome the problem of ferrotitanium powder falling downwards due to its own gravity, and ensure continuous and stable upward conveying of materials.

[0023] Specifically, the feeding mechanism 200 includes a feeding pipe 201 installed on the conveying pipe 101, a rotating shaft 204 rotatably installed inside the feeding pipe 201, and a feeding hopper 203 installed at the upper end of the feeding pipe 201. By adding the titanium iron powder raw material powder into the feeding hopper 203, the material can enter the feeding pipe 201 from the feeding hopper 203, and then enter the conveying pipe 101 through the feeding pipe 201 for pneumatic conveying.

[0024] Furthermore, a feeding plate 205 is arrayed on the rotating shaft 204. The feeding plate 205 is semi-circular. A motor 202 is installed on the side end of the feed pipe 201. The output shaft of the motor 202 is connected to the axis of the rotating shaft 204. When the motor 202 starts, it drives the rotating shaft 204 to rotate. The semi-circular feeding plate 205 on the rotating shaft 204 rotates accordingly. When the ferrotitanium powder in the feed hopper 203 falls onto the feeding plate 205, the ferrotitanium powder is intermittently fed into the conveying pipe 101 as the feeding plate 205 rotates, so that the ferrotitanium raw material powder can enter the conveying pipe 101 relatively evenly.

[0025] It is worth noting that the inner wall of the adjustable diameter pipe 301 is equipped with a flow-dispersing element 3012, which is hemispherical in shape and has a gradually decreasing density from bottom to top. In the lower part, the higher-density flow-dispersing element 3012 divides the airflow into multiple smaller airflows, increasing the contact area with the ferrotitanium raw material powder and promoting the uniform dispersion of the material in the airflow. In the upper part, the lower-density flow-dispersing element 3012 maintains appropriate disturbance while reducing energy loss, optimizing the conveying process, and further improving the overall conveying efficiency of the ferrotitanium raw material powder.

[0026] It is worth mentioning that the upper inner wall of the riser tube 103 is provided with a series of limiting grooves 104, and the lower outer surface of the discharge tube 303 is provided with a series of limiting sliders 304. The lower part of the discharge tube 303 is located inside the riser tube 103, and the limiting sliders 304 are slidably disposed within the limiting grooves 104. The limiting sliders 304 and the limiting grooves 104 allow for the sliding installation of the discharge tube 303.

[0027] It is worth noting that the discharge pipe 303, from bottom to top, includes a straight pipe section 3031, a variable diameter section 3032, and a bent discharge section 3033. The lower end of the straight pipe section 3031 is provided with a conical surface 3034, and the upper end of the adjustable variable diameter pipe 301 is located within the conical surface 3034. The conical surface 3034 of the discharge pipe 303 allows materials to smoothly enter the discharge pipe 303. Due to the smaller opening, the airflow velocity can be increased. When the arc plate 3011 is combined to form the adjustable variable diameter pipe 301, the upper end of the arc plate 3011 is displaced into the conical surface 3034, changing the support position of the discharge pipe 303. This allows the discharge pipe 303 to descend and connect with the upper end of the adjustable variable diameter pipe 301, facilitating material conveying and lifting. At the same time, the conical surface 3034 also facilitates the adjustment and unfolding of the adjustable variable diameter pipe 301.

[0028] Working Principle: This embodiment provides a feeding and lifting device for ferrotitanium powder raw materials. In use, the conveying fan 102 is first turned on, and the powerful airflow generated by the fan enters the conveying pipe 101. Ferrrotitanium powder raw materials are poured in from the feeding hopper 203. The motor 202 starts, driving the rotating shaft 204 to rotate. The semi-circular feeding plate 205 on the rotating shaft 204 rotates accordingly. When the ferrotitanium powder in the feeding hopper 203 falls onto the feeding plate 205, the ferrotitanium powder is intermittently fed into the conveying pipe 101 as the feeding plate 205 rotates, allowing the ferrotitanium powder to enter the conveying pipe 101 relatively evenly. 1. The ferrotitanium raw material powder entering the conveying pipe 101 moves towards the end of the riser pipe 103 under the push of the airflow. The material can be conveyed into the adjustable diameter pipe 301. When the amount of ferrotitanium raw material powder being conveyed is large or the airflow speed is insufficient, the electric push rod 302 works to extend the piston rod, causing the four arc-shaped plates 3011 to rotate and move closer to the center. The four arc-shaped plates 3011 can be combined to form the adjustable diameter pipe 301. At this time, the discharge pipe 303 loses its support under the action of the conical surface 3034 and can automatically descend to contact the upper end of the adjustable diameter pipe 301, thereby making the adjustable diameter pipe 301 and the... The lower end of the discharge pipe 303 is connected to an adjustable reducer 301, which is wider at the bottom and narrower at the top. This increases the airflow velocity, enhances the carrying capacity of the ferrotitanium raw material powder, and prevents the powder from sliding down due to its own weight. Simultaneously, the hemispherical baffle element 3012 installed on the inner wall of the adjustable reducer 301 plays a crucial role. Since the density of the baffle element 3012 gradually decreases from bottom to top, its density is higher at the lower part of the adjustable reducer 301, resulting in a stronger baffle effect on the airflow. This effectively divides the airflow into multiple smaller streams, increasing the contact area between the airflow and the ferrotitanium raw material powder, making the powder more... The ferrotitanium raw material powder is well dispersed in the airflow, further improving the conveying efficiency. As the ferrotitanium raw material powder moves upward, the density of the turbulence element 3012 gradually decreases, which can ensure appropriate disturbance to the airflow and avoid excessive energy loss. The ferrotitanium raw material powder enters the discharge pipe 303 after passing through the adjustable diameter pipe 301. The tapered surface 3034 set at the lower end of the straight pipe section 3031 of the discharge pipe 303 cooperates with the upper end of the adjustable diameter pipe 301, which helps to guide the ferrotitanium raw material powder smoothly into the discharge pipe 303. The ferrotitanium raw material powder is discharged through the bent pipe discharge section 3033 and conveyed to the production equipment at a higher position.
