Description

Technical Field

[0001] This utility model relates to the field of air separator technology, and in particular to an air separator for grain processing. Background Technology

[0002] A wind separator is an important piece of equipment in modern grain processing, mainly used for cleaning and grading grains. Its working principle is to generate specific airflow to separate impurities and substandard particles from qualified grains, thereby improving grain quality. A wind separator typically includes an inlet, a fan, a screen, and an outlet. During operation, grain enters the equipment through the inlet, and the airflow generated by the fan blows away light impurities (such as dust and straw), while the heavier, qualified grains are filtered out. This separation process not only removes impurities but also effectively improves the purity and market value of the grain. The advantage of using a wind separator lies in its efficient and rapid cleaning capabilities, enabling the processing of large quantities of grain in a limited time, thus improving production efficiency.

[0003] However, most of the existing air separators used in grain processing separate impurities that are lighter than the grain, and are not suitable for screening impurities that are heavier than the grain. As a result, large impurities are easily retained in the grain, which can cause the processing machine to malfunction during subsequent processing. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an air separator for grain processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grain processing air separator includes a housing with two symmetrically symmetrically arranged impurity outlets on its surface. A sieve plate is disposed between the two outlets and is fixedly connected to the inside of the housing. Multiple protective boxes are symmetrically fixedly connected to the bottom of the sieve plate, and each of the protective boxes is equipped with an impact mechanism for impacting the sieve plate. A second airflow is provided on one side of the housing, and an air roller is rotatably connected inside the second airflow. Multiple mixing chambers are provided on the surface of the air roller, and each of the mixing chambers is equipped with a mixing mechanism for mixing the grain. A third synchronous wheel is fitted onto one end of the air roller, and the surface of the third synchronous wheel is equipped with a rotation mechanism for rotating the air roller. By setting up the sieve plate, excessively large impurities can be separated, thereby preventing excessively large impurities from entering the grain.

[0007] As a further embodiment of this utility model, the impact mechanism includes a support column, which is fixedly connected to the inner surface of the protective box. An impact plate is sleeved on the surface of the support column, and the impact plate and the sieve plate are mutually coordinated. A spring is sleeved on the surface of the support column. The top end of the impact plate is fixedly connected to the bottom end of the impact plate, and the bottom end of the spring is fixedly connected to the inner surface of the protective box. A rack is fixedly connected to one side of the impact plate, and a first gear is engaged on the surface of the rack. A first rotating shaft is sleeved on one side of the first gear, and the first rotating shaft is rotatably connected to one side of the housing. A first synchronous wheel is sleeved on the surface of the first rotating shaft near the third synchronous wheel. By setting the impact plate, the sieve plate can be impacted.

[0008] As a further embodiment of this utility model, the stirring mechanism includes two support rings, which are respectively fixedly connected to both ends of the stirring chamber. The two support rings are rotatably connected to the same second rotating shaft. Multiple stirring rods are fixedly connected to the surface of the second rotating shaft, and the multiple stirring rods are slidably connected inside the stirring chamber. A second gear is fixedly connected to one end of the second rotating shaft, and a toothed ring is fitted on the surface of the second gear. The toothed ring is fixedly connected to one side of the inside of the shell. By setting up the stirring rods, the grain can be stirred.

[0009] As a further embodiment of this utility model, the rotating mechanism includes a motor, which is fixedly connected to the housing. The output shaft of the motor is fixedly connected to a fourth synchronous pulley. The surfaces of the third and fourth synchronous pulleys are fitted with the same second synchronous belt. The surface of the air roller near the first synchronous pulley is fitted with a second synchronous pulley. The surfaces of the first and second synchronous pulleys are fitted with the same first synchronous belt. The top of the housing has a feed inlet, and the bottom of the feed inlet has a discharge outlet. The side of the housing near the discharge outlet has a first air separator. Fans are fixedly connected to the ends of the housing near the first air separator and the second air separator. By setting the synchronous belt, the air roller and the first rotating shaft can be rotated.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a pre-screening technique using a sieve plate to separate grains, thus preventing excessively large impurities from entering the grains. This effectively solves the problem that most methods only separate impurities lighter than the grains, making it difficult to screen heavier impurities. Consequently, large impurities tend to remain inside the grains, leading to machine malfunctions during subsequent processing. A sieve plate is installed at the bottom of the feed inlet. This sieve plate allows for the screening of impurities larger than the grains, preventing them from moving downwards with the grains. Because the first gear is designed with a missing gear, it will stop driving the impact plate downwards when it rotates to a certain angle. A spring is installed at the bottom of the impact plate. When the first gear and rack no longer engage, the spring will drive the impact plate to quickly reset, allowing it to impact the sieve plate. This impact generates vibration in the sieve plate, preventing blockage. Attached Figure Description

A rack 204 is fixedly connected to one side of the impact plate 203, and a first gear 205 is fitted on the surface of the rack 204.

A first synchronous wheel 207 is sleeved on the surface of the first rotating shaft 210 near the third synchronous wheel 307. By setting the impact plate 203, the sieve plate 2 can be impacted.

[0024] Reference Figure 6 and Figure 7 In a preferred embodiment, the stirring mechanism includes two support rings 302, which are fixedly connected to both ends of the stirring chamber 301. The two support rings 302 are rotatably connected to the same second rotating shaft 303. Multiple stirring rods 304 are fixedly connected to the surface of the second rotating shaft 303, and the multiple stirring rods 304 are slidably connected inside the stirring chamber 301.

The ends of the housing 1 near the first air separator 104 and the second air separator 105 are fixedly connected to a fan 106. Through the setting of the synchronous belt, the air roller 3 and the first rotating shaft 210 can be rotated.

[0026] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the blower 106 and motor 308 are started first, and then the grain is poured into the housing 1 through the feed inlet 101. A sieve plate 2 is installed at the bottom of the feed inlet 101. Through the setting of the sieve plate 2, impurities larger than the grain can be screened to prevent them from moving down with the grain. A second synchronous belt 310 is installed on the output shaft of the motor 308, and the other end of the second synchronous belt 310 is installed on one side of the air roller 3. Thus, when the motor 308 is started, the air roller 3 will rotate synchronously. A first synchronous belt 208 is also installed on one side of the air roller 3, and the other end of the first synchronous belt 208 is engaged with the first rotating shaft 210. So when the air roller 3 rotates, the first rotating shaft 210 will also rotate synchronously. A first gear 205 is sleeved on the surface of the first rotating shaft 210, and the first gear 205 is engaged with the rack 204 on one side of the impact plate 203. So when the first gear 205 rotates, it can make the impact plate 203 move downward. However, the first gear 205 is set with a missing gear, so when the first gear 205 rotates to a certain angle, it will not be able to continue to drive the impact plate 203. The impact plate 203 is lowered, and a spring 206 is installed at the bottom. When the first gear 205 and the rack 204 no longer engage, the spring 206 will drive the impact plate 203 to quickly reset, so that it can impact the screen plate 2. The impact can make the screen plate 2 vibrate, thus preventing the screen plate 2 from clogging. A wind roller 3 is installed at the bottom of the screen plate 2, and multiple mixing chambers 301 are opened on the surface of the wind roller 3. After the grain passes through the screen plate 2, it will enter the mixing chamber 301. Multiple stirring rods 304 are installed inside the mixing chamber 301, and the same second rotor is installed between the multiple stirring rods 304. A second gear 305 is installed at one end of the second rotating shaft 303. The second gear 305 cooperates with the gear ring 306 inside the housing 1. So when the wind roller 3 drives the stirring rod 304 to rotate, the stirring rod 304 will also rotate on its own axis. By stirring the grain with the stirring rod 304, the phenomenon of grain and impurities sticking together can be avoided. Two fans 106 are installed on one side of the housing 1. The two fans 106 cooperate with the first air separation port 104 and the second air speed 105. So when the grain is on the side of the first air separation port 104 and the second air speed 105, impurities can be separated.
