Description

Technical Field

[0001] The utility model belongs to the technical field of spirulina powder production, in particular to a circulating air spirulina powder conveying device. Background Art

[0002] Spirulina powder, as the name implies, is a powder made by grinding spirulina. Due to the characteristics of spirulina itself, spirulina powder has a certain preventive and inhibitory effect on the three highs, and has a certain therapeutic effect on chronic gastrointestinal diseases, gastric and duodenal ulcers. It can relieve constipation and treat hemorrhoid scars, and can beautify and lose weight. In the production process of spirulina powder, it is often necessary to transport spirulina powder. In order to facilitate its transportation, a conveying device is used;

[0003] The existing document with publication number CN217275434U discloses a circulating conveying structure for spirulina processing, comprising a base, a connecting frame fixedly connected to the top of the base, a feeding pipe fixedly connected to the upper end of the connecting frame, an air inlet pipe and an air exhaust pipe fixedly connected to the upper and lower ends of the feeding pipe, respectively, an air inlet fan and an air exhaust fan are installed in the air inlet pipe and the air exhaust pipe, respectively, a rotating motor is fixedly provided on the top of the air inlet pipe by bolts, and a feeding hopper is fixedly connected to the top of the air inlet pipe;

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the above-mentioned circulating conveying structure, a feed hopper is fixedly connected to the top of the air inlet pipe, and spirulina powder is added into the air inlet pipe through the feed hopper, so that the spirulina powder is mixed with the airflow in the air inlet pipe. However, it lacks a structure to assist the mixing of spirulina powder and airflow, resulting in insufficient mixing of spirulina powder and airflow, which affects the conveying efficiency of spirulina powder.

[0006] 2. In the above-mentioned circulating conveying structure, a second filter is fixedly provided at the bottom of the exhaust pipe, and the airflow and spirulina powder are separated by the second filter. However, during the separation process, part of the spirulina powder will adhere to the second filter and cause blockage, thereby affecting the unloading efficiency of the spirulina powder.

[0045] See also Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, on the basis of the specific embodiment 1, a discharge pipe 15 is penetrated on one side outer wall of the feed shell 1, and a one-way valve is further provided on the discharge pipe 15 to limit the direction of airflow movement, and a discharge assembly 3 is provided at one end of the discharge pipe 15 away from the feed shell 1, and a discharge shell 31 in the discharge assembly 3 is located on one side of the feed shell 1, and the end of the discharge pipe 15 away from the feed shell 1 penetrates one side outer wall of the discharge shell 31 and extends to the inner side of the discharge shell 31, and a sieve plate 32 is fixedly connected to the upper part of the inner part of the discharge shell 31, and the surface of the sieve plate 32, etc. Sieve holes 321 are provided at intervals, and the diameter of the sieve holes 321 is smaller than the particle size of the spirulina powder.

The center positions of the front and rear end surfaces of the discharge shell 31 are fixedly connected with electric push rods 333, and the output ends of the electric push rods 333 pass through the end surface of the discharge shell 31 and are fixedly connected to the scraper 33.

[0046] Specifically, a return air pipe 16 passes through the top center position of the discharge shell 31, and one end of the return air pipe 16 away from the discharge shell 31 passes through the lower side of the outer wall of the feed shell 1 and extends to the lower inside of the feed shell 1. A discharge pipe 311 passes through the bottom center position of the discharge shell 31, and an L-shaped seat 312 is welded on the upper side of the outer wall of the other side of the discharge shell 31, and a connecting groove 3121 is opened on the horizontal support arm of the L-shaped seat 312.

Specific embodiment three

[0050] See also Figure 1 , Figure 2 and Fig. 9As shown, based on Example 1 and Example 2, a heating box 4 is fixedly connected above the front end surface of the feed shell 1, and a plurality of groups of resistance wires 41 are fixedly connected to the interior of the heating box 4 at equal intervals in the horizontal direction, and both ends of the resistance wires 41 pass through the front end surface of the heating box 4, and an air outlet pipe 42 and an air inlet pipe 43 are respectively penetrated on both sides of the front end surface of the heating box 4, and the ends of the air outlet pipe 42 and the air inlet pipe 43 away from the heating box 4 respectively pass through both sides of the front end surface of the feed shell 1 and extend to the interior of the feed shell 1.

[0052] Furthermore, a battery is also provided on the heating box 4, and the two ends of the resistance wire 41 are electrically connected to the positive and negative electrodes of the battery through wires. This is a common existing technology, so it is not shown in detail in the text and figures.

[0053] The operation process of this embodiment is: turn on the power supply of the resistance wire 41 so that the battery supplies power to the resistance wire 41. After the resistance wire 41 is energized, it emits heat, thereby heating the air in the heating box 4. Since the temperature in the heating box 4 rises and the pressure increases, the one-way valve on the air outlet pipe 42 is opened at this time. Under the action of pressure, the hot air in the heating box 4 enters the feed shell 1 through the air outlet pipe 42, so that the temperature in the feed shell 1 rises, thereby drying the spirulina powder in the feed shell 1. Finally, the one-way valve on the air inlet pipe 43 is opened. At this time, since the pressure in the feed shell 1 increases, the air in the feed shell 1 enters the heating box 4 through the air inlet pipe 43 for secondary heating, thereby drying the spirulina powder in the feed shell 1.
