Description

Technical Field

[0001] This utility model relates to the field of porcine hemoglobin powder production, and in particular to a spray drying atomizer for preventing clogging in porcine hemoglobin powder production. Background Technology

[0002] In the spray drying production of porcine hemoglobin powder, the storage tank and atomization process face practical challenges: porcine hemoglobin solution is highly viscous and rich in protein, and long-term static storage in the storage tank easily leads to the adhesion of proteins to the inner wall of the tank, forming a scale layer that is difficult to remove. This scale not only reduces the effective capacity of the storage tank but may also cause localized corrosion of the equipment due to thickening, affecting its service life. Meanwhile, traditional atomizers often use single-axis stirring or static mixing methods, which are insufficient for stirring highly viscous solutions. Single-axis stirring is difficult to cover the edges and bottom of the tank, easily causing uneven solution concentration. Long-term storage further exacerbates protein precipitation and aggregation, forming a gel-like substance adhering to the bottom of the tank, affecting subsequent atomization quality and nozzle unobstructed flow, resulting in unstable product quality and reduced production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a spray dryer atomizer for preventing clogging in the production of porcine blood cell protein powder, in order to solve the problems mentioned in the background art.

It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0014] This utility model provides a technical solution: a spray dryer atomizer for preventing clogging in the production of porcine blood globulin powder, such as... Figure 1 , Figure 2 As shown, it includes an outer shell 1, a liquid storage tank 2 inside the outer shell 1, a coaxial counter-propeller mechanism 3 on the liquid storage tank 2, a stirring and scraping structure 4 connected to the power below the coaxial counter-propeller mechanism 3, and a centrifugal atomizing mechanism 5 below the liquid storage tank 2.

[0015] like Figure 2 , Figure 3 As shown, the coaxial counter-propeller mechanism 3 includes a motor 301, a working cylinder 302 below the motor 301, a transmission rod 303 connected to the output end of the motor 301, a bevel gear 304 on the transmission rod 303, a bevel gear 305 movably disposed inside the working cylinder 302, the bevel gear 304 meshing with the bevel gear 305, a transmission sleeve 306 movably disposed on the transmission rod 303, a bevel gear 307 on the top of the transmission sleeve 306, the bevel gear 305 meshing with the bevel gear 307, the transmission rod 303 and the transmission sleeve 306 extending into the storage tank 2, and a sealed bearing 308 at the contact point between the transmission rod 303 and the transmission sleeve 306 and the storage tank 2.

[0016] like Figure 2 , Figure 5As shown, the stirring and scraping structure 4 includes a rotating connector 401, which is rotatably disposed at the bottom of the storage tank 2. The top of the rotating connector 401 is connected to the transmission rod 303. An anchor-type inner wall scraper 402 is provided on the rotating connector 401. The portion of the transmission outer sleeve 306 extending into the storage tank 2 is provided with a stirring rod 403.

[0017] like Figure 5 As shown, the top of the storage tank 2 is provided with an inlet pipe 201, and the bottom of the storage tank 2 is provided with a drain port 202. Several drain ports 202 are arranged in a ring around the rotating connector 401. Below the drain port 202 is a delivery funnel 203. Below the delivery funnel 203 is an electrically controlled on / off valve 204. Below the electrically controlled on / off valve 204 is a delivery pipe 205. The bottom end of the delivery pipe 205 is provided with a rotating bearing 206.

[0018] like Figure 6 As shown, a support frame 501 is provided on the rotary bearing 206, and a motor 502 is provided at the other end of the support frame 501. A rotating rod 503 is provided below the motor 502, and a gear 504 is connected to the bottom end of the rotating rod 503. A delivery pipe 505 is connected below the rotary bearing 206, and a gear ring 506 is provided on the delivery pipe 505. The gear 504 meshes with the gear ring 506, and a rotary atomizer 507 is provided below the gear ring 506.

[0019] In practice, before use, the porcine hemoglobin solution is transported to the storage tank 2 through the input pipe 201. Motor 301 is started, driving the transmission rod 303 to rotate. The bevel gear 304 on the transmission rod 303 drives the bevel gear 305 to rotate, which in turn drives the bevel gear 307 on the transmission sleeve 306. This causes the transmission rod 303 and the transmission sleeve 306 to rotate in opposite directions, thereby driving the stirring and scraping structure 4 to stir the solution in the storage tank 2 and simultaneously scrape away any material that may be adhering to the tank wall to prevent blockage.

[0020] When the electrically controlled on / off valve 204 is opened, the solution in the storage tank 2 is delivered to the delivery pipe 505 of the centrifugal atomizing mechanism 5 via the delivery funnel 203, delivery pipe 205, and rotating bearing 206. The second motor 502 is started, driving the rotating rod 503 and gear 504 to rotate. The gear 504 meshes with the gear ring 506, driving the delivery pipe 505 and the rotating atomizer 507 below to rotate at high speed. Under centrifugal force, the solution is thrown out from the rotating atomizer 507, forming fine droplets that enter the subsequent spray drying stage.

[0021] During operation, continuously monitor the solution level and agitation in storage tank 2, and adjust the solution delivery rate via the electrically controlled on / off valve 204. If poor solution delivery or atomization is detected, adjust the speeds of motor 301 and motor 502 via an external controller to optimize agitation and atomization.

[0022] After use, first close the electrically controlled on / off valve 204 to stop the solution delivery. Continue running motor 1 301 and motor 2 502 for a period of time to clean the storage tank 2 and drain the residual solution in the delivery pipe 505. Then turn off motor 1 301 and motor 2 502 to complete the equipment operation.
