DETAILED DESCRIPTION

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0025] Specific embodiment 1 of the drying and collecting device for blood globulin powder of the present invention, as Figure 1 、 Figure 2As shown, the drying and collecting equipment for hemoglobin powder includes a main shell 1, an air heating structure 2, an atomizing structure 3 and a feeding mechanism. A first hot air port 101, a second hot air port 102 and a spray head 110 are provided in the inner cavity of the main shell 1; the first hot air port 101 and the second hot air port 102 are respectively arranged on opposite side walls of the main shell 1, and the air flow direction of the first hot air port 101 is parallel to the air flow direction of the second hot air port 102 and is staggered to form a vortex airflow zone in the inner cavity of the main shell 1; the spray head 110 is arranged at one axial end of the vortex airflow zone, and the main shell 1 is also provided with a discharge port 120 located at the other axial end of the vortex airflow zone, and the feeding mechanism is installed at the discharge port 120; a mist pipeline 30 is connected between the atomizing structure 3 and the spray head 110, and the air heating structure 2 and the first hot air port 101, and the air heating structure 2 and the second hot air port 102 are connected by a gas pipeline 20.

[0026] The drying and collecting equipment for hemoglobin powder adopts an overall structural design of a main shell 1, an air heating structure 2, an atomizing structure 3 and a feeding mechanism. A first hot air port 101 and a second hot air port 102 are respectively arranged on opposite side walls of the main shell 1. The airflow direction of the first hot air port 101 is parallel to the airflow direction of the second hot air port 102 and they are staggered. That is, the two airflows in opposite and staggered directions meet in the inner cavity of the main shell 1 to form a vortex airflow area. The hot air in the vortex airflow area has a high density and a fast flow speed, and has higher heat and kinetic energy.

[0027] The spray head 110 is arranged at one axial end of the vortex airflow zone, and the atomizing structure 3 is used to generate mist from the concentrated blood cell solution. The mist is sprayed into the vortex airflow zone through the spray head 110 via the mist pipeline 30. The mist enters the vortex airflow zone and is fully contacted and mixed with the hot air, and the mixing is more uniform. In addition, the mist generates a synchronous vortex motion with the movement of the hot air, which prolongs the heating time of the mist in the inner cavity of the main shell 1, effectively evaporates water to obtain thoroughly dried blood cell protein powder, and has a good drying effect and higher powder making efficiency.

[0028] In this embodiment, the main housing 1 includes a cylindrical body 10, a top cover 11 fixed to the upper portion of the cylindrical body 10, and a bottom plate fixed to the lower portion of the cylindrical body 10. A spray head 110 is disposed on the top cover 11, a discharge port 120 is disposed on the bottom plate, a first hot air outlet 101 and a second hot air outlet 102 are disposed at opposing positions on the sidewalls of the cylindrical body 10, and the axis of the vortex airflow zone is parallel to the axis of the cylindrical body 10. The cylindrical body 10 is cylindrical in shape, and its axis extends vertically.

[0029] The first hot air outlet 101 and the second hot air outlet 102 are arranged symmetrically about the central axis of the cylindrical body 10. That is, the first hot air outlet 101 is arranged on the wall of the cylindrical body 10 on the left side of the central axis, and the second hot air outlet 102 is arranged on the wall of the cylindrical body 10 on the right side of the central axis. In addition, the airflow of the first hot air outlet 101 flows through the rear area inside the cylindrical body 10, and the airflow of the second hot air outlet 102 flows through the front area inside the cylindrical body 10. Figure 2 As shown, two hot air flows in opposite directions and staggered front to back meet in the middle of the cylindrical barrel 10 to form a vortex airflow area, so that the mist and the hot air are fully contacted and mixed, extending the heating time of the mist in the inner cavity of the main shell 1, and effectively evaporating the moisture to obtain thoroughly dried hemoglobin powder.

[0030] An exhaust port 122 is located on the bottom plate near the discharge port 120. This port is fitted with a breathable filter cloth. Specifically, the breathable filter cloth is a non-woven filter cloth. The micropores of the non-woven filter cloth allow heated air and water vapor to escape, keeping the hemoglobin powder trapped within the breathable filter cloth, effectively separating gas and particles. To meet different usage requirements, the breathable filter cloth can be made of synthetic fiber cloth, glass fiber cloth, or cotton canvas, all of which can also separate gas and particles.

[0031] The bottom plate is a bucket-shaped structure 12 with a lower center and a higher periphery, and a discharge port 120 is located in the middle of the bucket-shaped structure 12. Specifically, the bucket-shaped structure 12 is conical in shape, and a powder blocking structure is provided on its upper side. Multiple powder blocking structures are arranged at intervals along the circumference of the bucket-shaped structure 12. Furthermore, each powder blocking structure is a powder blocking plate 121, which extends outward from the center of the bucket-shaped structure 12 and is arranged at an angle opposite to the rotation direction of the vortex airflow zone.

[0032] In other words, the powder retaining plates 121 are straight plates whose length does not extend radially along the bucket-shaped structure 12, but rather is arranged at an angle in the opposite direction of the vortex airflow zone. Under the guiding action of the powder retaining plates 121, the vortex airflow forms a centripetal distribution motion between the powder retaining plates 121. Due to the centripetal sweeping force generated by the vortex airflow, the powder particles move along the sides of the powder retaining plates 121 toward the discharge port 120, accelerating the discharge of the powder particles and preventing the continuous accumulation of hemoglobin powder in the bucket-shaped structure 12, preventing smooth discharge.

[0033] In other embodiments, in order to meet different usage requirements, the powder baffle can be designed as an arc-shaped powder baffle, which is bent outward from the center of the bucket-shaped structure in the opposite direction of the rotation of the vortex airflow zone. The arc-shaped side of the arc-shaped powder baffle can also be used to make the vortex airflow form a centripetal distribution motion between the arc-shaped powder baffles, thereby accelerating the discharge speed of the powder particles.

[0034] The feeding mechanism is a spiral feeding mechanism 4, comprising a feeding tube 40, a spiral structure, and a drive motor. The drive motor is in driving connection with the spiral structure. A discharge pipe 13 is connected between the discharge port 120 of the bottom plate and the feeding tube 40. Furthermore, the spiral structure comprises a spiral brush 41 arranged in a spiral shape, which frictionally engages with the inner wall of the feeding tube 40. Powder particles enter the feeding tube 40 through the discharge pipe 13, and the bristles of the spiral brush 41 scrape the inner wall of the feeding tube 40, thereby continuously conveying the powder particles in the feeding tube 40 until discharge. The spiral brush 41 is designed to completely scrape and convey the hemoglobin powder in the tube.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
