[0002] This utility model relates to the field of powder refining agent production technology, and in particular to a powder refining agent dispensing machine. Background Technology

[0003] At the end of the production process of spray-dried refining agent, it needs to be packaged. Generally, a filling machine is used for filling. The filling machine can fill various packaging containers such as bags, cans, bottles and tubes into quantitative quantities.

[0004] In existing technologies, the feeding method of the dispensing machine relies on the dispensing screw to discharge the material. However, in actual situations, the powder may contain moisture during the processing, which can easily cause it to stick together, making the material flow poorly inside the screw and resulting in uneven discharge, affecting the dispensing efficiency and quality. Therefore, a powder spraying refining agent dispensing machine is proposed to solve this problem. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] A powder refining agent dispensing machine includes: a dispensing hopper 1 with a powder outlet 101 at the bottom; a hopper cover 2 located on the upper part of the dispensing hopper 1, with an inlet 201 and a through hole 202; a dispensing screw 3 passing through the through hole 202 and extending to the powder outlet 101 at the bottom of the dispensing hopper 1; and a heat exchange shell 4 fitted onto the lower part of the dispensing hopper 1, with an internal cavity for gas flow. An air inlet pipe 401 is located on the upper part of one side of the heat exchange shell 4, and an installation hole 402 is located on the lower part of the other side of the heat exchange shell 4. High-temperature gas enters the cavity through the air inlet pipe 401 to heat the dispensing hopper 1 and dry the powder inside the dispensing hopper 1.

[0024] In one embodiment, such as Figure 1 As shown, the powdered refining agent is added through the feed hole 201 of the hopper cover 2. The equipment is started. The end of the dispensing screw 3 located outside the dispensing hopper 1 is connected to the output shaft of the motor (not shown in the figure). The motor drives the dispensing screw 3 to rotate. The rotation of the dispensing screw 3 drives the powdered refining agent to be discharged for dispensing.

[0025] To reduce the adhesion of the powdered refining agent to the inner wall of the dispensing hopper 1 and the dispensing screw 3, in one embodiment, such as Figure 2 , 3 As shown, the surface of the dispensing screw 3 and the interior of the dispensing hopper 1 are provided with an impact rod 301 and a stirring rod 302 from top to bottom; the interior of the dispensing hopper 1 is provided with spring plates 103 arranged in a circular array, and the spring plates 103 and the impact rod 301 are at the same horizontal height.

[0026] The rotation of the dispensing screw 3 drives the stirring rod 302 to rotate, which stirs the sprayed refining agent and reduces the agglomeration of the sprayed refining agent itself. At the same time, the dispensing screw 3 also drives the impact rod 301 to rotate. During the rotation, the impact rod 301 continuously collides with the spring plate 103 inside the dispensing hopper 1, generating vibration and reducing the adhesion of the sprayed refining agent to the inner wall of the dispensing screw 3 and the dispensing hopper 1.

[0027] To further reduce adhesion or clumping caused by factors such as moisture content in the powdered refining agent, in one embodiment, such as Figure 1 , 3As shown in Figure 4, an air outlet assembly 5 is installed in the mounting hole 402. The air outlet assembly 5 includes an expanded end 502 located outside the heat exchange shell 4 and an installation tube 501 located in the mounting hole 402 and extending into the heat exchange shell 4. The side wall of the end of the installation tube 501 extending into the heat exchange shell 4 is provided with a plurality of air outlet holes 5011. A limiting plate 503 is provided inside the expanded end. A spring 504 is provided between the limiting plate 503 and the bottom of the installation tube 501. The diameter of the limiting plate 503 is larger than the diameter of the installation tube 501, and the diameter of the limiting plate 503 is smaller than the diameter of the expanded end 502.

[0028] High-temperature gas enters the cavity inside the heat exchange shell 4 through the inlet pipe 401 located above the heat exchange shell 4. When the gas pressure inside the heat exchange shell 4 is less than the elastic force of the spring 504, the limiting plate 503 closes the connection between the expansion end 502 and the mounting pipe 501, allowing the gas to fill the cavity of the heat exchange shell 4. This enables the high-temperature gas to fully exchange heat with the wall of the dispensing hopper 1, quickly and effectively removing moisture, improving the flowability of the powder, and drying the powdered refining agent inside the dispensing hopper 1. The effect of this further reduces the adhesion and clumping of the powdered refining agent itself, thereby improving the uniformity of the powdered refining agent output. When the air pressure inside the mounting pipe 501 is greater than the pressure of the spring 504, the gas inside the mounting pipe 501 pushes the limiting plate 503 to move towards the expansion end 502, and the gas in the cavity of the heat exchange shell 4 flows out, so as to protect the safe operation of the equipment and avoid excessive air pressure, which could cause the equipment to deform. At the same time, a one-way valve is provided on the air inlet pipe 401 to ensure the direction of gas flow.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
