Technical Field
[0001] This utility model relates to the field of aquatic feed additive production technology, specifically to an airflow balancing mixing chamber for feed additive production. Background Technology
[0002] In the production process of aquatic feed additives, an aquatic feed additive often involves multiple components, which requires a practical mixing device to mix the multiple components evenly. The mixing effect of the mixing device directly affects the use effect of the aquatic feed additive. Existing aquatic feed additive mixing devices mostly use agitators to mix. When the additive components involve large particles that clump together, they need to be dispersed and crushed by a pulverizer before being mixed with other components, which affects the efficiency of production and processing.
[0003] According to a public announcement of a mixing device for the production of aquatic feed additives (Announcement No.: CN209138520U), the above application includes a gas mixing chamber and a stirring mixing chamber that are connected at the top and bottom to form a gourd-shaped structure. The inner wall of the gas mixing chamber is provided with a gas equalization injection component for injecting gas into the gas mixing chamber. A transverse spiral stirring component is provided in the stirring mixing chamber. The lower end of the stirring mixing chamber is provided with a discharge port.
[0004] However, the nozzles of the above-mentioned airflow mixing chamber are only set on the inner wall of the chamber. The airflow from the wall nozzles mainly develops along the wall or tangentially, forming a circulation or vortex. This does not adequately drive the powder in the central area of the chamber, easily forming a dead zone in the center, resulting in insufficient mixing in the central area and reduced mixing uniformity. In view of this, we propose an airflow balance mixing chamber for feed additive production. Utility Model Content
[0005] The purpose of this invention is to provide an airflow balancing mixing chamber for feed additive production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an airflow balancing mixing chamber for feed additive production, comprising a chamber body, a feed cover on the top of the chamber body, and an air mixing assembly inside the chamber body, the air mixing assembly comprising:
[0007] The motor has a rotating shaft fixedly connected to its output end. An air inlet groove is provided on the side wall of the rotating shaft, and an air inlet pipe is sleeved on the side wall of the rotating shaft.
[0008] The first trachea has a push plate fixedly connected to its end face, and a blocking inclined plate fixedly connected to the side wall of the push plate.
[0009] A stirring rod, the end face of which is fixedly connected to a stop block.
[0010] Preferably, a discharge flange is fixedly connected to the bottom of the silo body, and the bottom of the discharge flange is fixedly connected to a solenoid valve to control the feeding of feed.
[0011] Preferably, the motor is fixedly connected to the top end face of the chamber, and the rotating shaft is hollow, allowing gas to enter the interior of the rotating shaft.
[0012] Preferably, the air intake pipe is located outside the air intake slot, and the air intake pipe is fixedly connected to an external air supply device, through which air is supplied to the air intake pipe and the rotating shaft.
[0013] Preferably, the air pipe is fixedly connected to the side wall of the rotating shaft, the push plate is movably connected to the bottom of the chamber, and the push plate has an air outlet on the side near the obstruction plate.
[0014] Preferably, the stirring rod is fixedly connected to the side wall of the rotating shaft, and the number of stirring rods is set in several groups, with the lengths of the stirring rods in the several groups being different.
[0015] Preferably, the stirring rod is tubular, the baffle is inclined, and the baffle extends above the stirring rod to reduce the probability of particles entering the interior of the stirring rod.
[0016] Preferably, an air pipe II is fixedly connected to the side wall of the rotating shaft, a wall scraper block is fixedly connected to the end face of the air pipe II, and an oblique jet hole is fixedly connected to the side wall of the wall scraper block.
[0017] Compared with the prior art, this utility model provides an airflow balancing mixing chamber for feed additive production, which has the following beneficial effects:
[0018] 1. This airflow balancing mixing chamber for feed additive production uses a pneumatic mixing component. Part of the gas is ejected from the air outlet on one side of the push plate, which creates a local airflow while rotating and pushing, picking up powder from the bottom or corners and improving bottom circulation. The other part of the gas is ejected through the end face of the stirring rod, which directly introduces the airflow into the central area, enhancing central circulation, helping to disperse materials with different densities, improving the uniformity of components with different densities, and guiding materials with inclined plates and blocks to guide falling materials to other positions in the chamber, reducing the amount of accumulation above the nozzle, keeping the area near the nozzle relatively clean, and reducing the risk of blockage when the jet stops.
[0019] 2. The airflow balance mixing chamber for feed additive production has a wall scraper that can scrape off powder adhering to the wall during rotation, preventing sedimentation and avoiding dead corners caused by powder accumulation on the wall, thus reducing local blockage. The oblique jet can blow the scraped powder towards the center of the chamber, forming a local airflow circulation, which is conducive to three-dimensional circulation and mixing of materials and improves the uniformity of mixing.

[0027] like Figures 1-6 As shown, this utility model provides a technical solution: an airflow balancing mixing chamber for feed additive production, including a chamber body 1, a feed cover 2 on the top of the chamber body 1, and an air mixing component 3 inside the chamber body 1. The air mixing component 3 includes a motor 301, a rotating shaft 302, an air inlet groove 303, an air inlet pipe 304, an air pipe 305, a push plate 306, a baffle plate 307, a stirring rod 308, and a baffle block 309.
[0028] In one embodiment of this utility model, a motor 301 is fixedly connected to the top end face of the chamber 1, and a rotating shaft 302 is fixedly connected to the output end of the motor 301. An air inlet groove 303 is provided on the side wall of the rotating shaft 302. The rotating shaft 302 is hollow, so that gas can enter the interior of the rotating shaft 302. An air inlet pipe 304 is sleeved on the side wall of the rotating shaft 302. The air inlet pipe 304 is located outside the air inlet groove 303. The air inlet pipe 304 is fixedly connected to an external air supply device, and air is supplied to the air inlet pipe 304 and the rotating shaft 302 through the external air supply device.
[0029] Air pipe 305 is fixedly connected to the side wall of rotating shaft 302. A push plate 306 is fixedly connected to the end face of air pipe 305. A shielding inclined plate 307 is fixedly connected to the side wall of push plate 306. Push plate 306 is movably connected to the bottom of chamber 1. An air outlet is provided on the side of push plate 306 near shielding inclined plate 307.
[0030] The stirring rod 308 is fixedly connected to the side wall of the rotating shaft 302. Several sets of stirring rods 308 are provided, and the lengths of the stirring rods 308 are different. A stop block 309 is fixedly connected to the end face of the stirring rod 308. The stirring rod 308 is arranged in a tubular shape, and the stop block 309 is arranged in an inclined shape. The stop block 309 extends above the stirring rod 308 to reduce the probability of particles entering the interior of the stirring rod 308.
[0031] The bottom of the silo 1 is fixedly connected to a discharge flange 7, and the bottom of the discharge flange 7 is fixedly connected to a solenoid valve to control the feeding of feed.
[0032] Motor 301 drives shaft 302, stirring rod 308 and push plate 306 to rotate. Push plate 306 is movably connected to the bottom of bin 1. Push plate 306 floats slightly or adheres to the bottom surface when rotating, which can push up the residual material at the bottom to avoid sedimentation and ensure that the bottom material also enters the circulation mixing. Stirring rod 308 can drive the material near the shaft and bottom when rotating, break up sediment clumps, prevent dead corners and improve the uniformity of mixing.
[0033] An external air supply device supplies air to the air inlet pipe 304 and the rotating shaft 302. Part of the air is ejected through the air pipe 305 and the push plate 306 from the air outlet slot on the side of the push plate 306 near the obstruction inclined plate 307. This creates a local airflow while the shaft is rotating, which picks up the powder at the bottom or corners and improves the bottom circulation. Another part of the air is ejected through the end face of the stirring rod 308. The air jet from the end face of the stirring rod 308 directly introduces the airflow into the central area, enhancing the central circulation, helping to disperse materials with different densities, and improving the uniformity of the components with different densities.
[0034] A baffle plate 307 is fixedly connected to the side wall of the push plate 306, and a baffle 309 extends above the stirring rod 308. The baffle plate 307 and the baffle 309 guide the material and guide the falling material to other positions in the silo 1, reduce the amount of material accumulated above the nozzle, keep the area near the nozzle relatively clean, and reduce the risk of blockage when the jet stops.
[0035] In addition, an air pipe 4 is fixedly connected to the side wall of the rotating shaft 302, a wall scraper 5 is fixedly connected to the end face of the air pipe 4, and an oblique jet nozzle 6 is fixedly connected to the side wall of the wall scraper 5. The air pipe 4 guides the airflow to the end face and side wall nozzle of the wall scraper 5. The wall scraper 5 fits against the inner wall of the chamber 1. When rotating, it can scrape off the powder adhering to the wall, avoid deposition, prevent the accumulation of powder on the wall to form dead corners, and reduce local blockage. The oblique jet can blow the scraped powder towards the center of the chamber 1 to form a local airflow circulation, which is conducive to the three-dimensional circulation and mixing of materials and improves the mixing uniformity. The oblique direction of the nozzle itself is not easily blocked by the scraped powder.
[0036] In this invention, during use, the stirring rod 308 and the push plate 306 rotate. The push plate 306 is movably connected to the bottom of the chamber 1. When rotating, the push plate 306 floats slightly or adheres to the bottom surface, which can push up the residual material at the bottom to avoid sedimentation and ensure that the bottom material also enters the circulation mixing. When rotating, the stirring rod 308 can drive the material near the axis and the bottom to break up the sediment clumps. A part of the gas is ejected through the air pipe 305 and the push plate 306 from the air outlet slot opened on the side of the push plate 306 near the shielding inclined plate 307. This can form a local airflow while rotating and pushing, which can roll up the powder at the bottom or corners and improve the bottom circulation. Another part of the gas is ejected through the end face of the stirring rod 308. The jet from the end face of the stirring rod 308 directly introduces the airflow into the axis area, enhances the central circulation, and improves the uniformity of the density difference components.
[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
