Description

Technical Field

[0001] The invention belongs to food processing equipment, and mainly relates to a corn liquid atomizing nozzle used for corn flour processing. Background Art

[0002] Corn is one of the most widely distributed food crops in the world. Since corn contains a large amount of lecithin, linoleic acid, cereal alcohol, vitamin E, cellulose and other ingredients, it has a variety of health benefits such as lowering blood pressure, lowering blood lipids, anti-atherosclerosis, preventing intestinal cancer, beautifying and delaying aging, and is a healthy food. However, since the corn flour particles produced by the traditional dry processing method are coarse and hard, the food made has a poor taste, poor palatability, and is not easy to digest, and people have always disliked eating it. In order to solve the problems existing in the above-mentioned traditional dry corn flour processing method, a wet corn flour production and processing method has begun to be applied in recent years. The fineness of the corn flour processed by this method is about twice that of wheat flour, and the edible taste is greatly improved. The key technology in the wet corn flour processing process is drying, and the core equipment of the drying operation is the atomizing nozzle of the corn liquid. Since the corn liquid has a high viscosity during drying, the existing atomizing nozzle is very easy to be blocked, which not only has a poor atomization effect of the corn liquid, but also affects the quality of the corn flour after drying, reduces the flour yield, and has low production efficiency, and cannot achieve the purpose of industrial production. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, combine with the actual needs of industrial production and processing of corn flour, and study and design a corn liquid atomizing nozzle with a new structure, so as to achieve the purpose of preventing the nozzle from being easily blocked during the atomization of the corn liquid, achieving good atomization effect, high efficiency, strong applicability, and providing high-quality atomized corn liquid for the drying tower.

[0004] The purpose of the invention is achieved in this way: a cylindrical nozzle core is installed in the barrel cavity of a cylindrical barrel-shaped nozzle shell in an axially movable and adjustable manner through a threaded connection, the lower end of the cylindrical nozzle core is composed of a cylinder and an inverted cone as a whole, a liquid input channel is axially opened in the center of the cylindrical nozzle core, the inner wall surface of the bottom wall of the barrel cavity of the cylindrical barrel-shaped nozzle shell is in an inverted cone shape as a whole, and a spiral groove is arranged on the inverted cone inner wall surface, an annular gap is arranged between the cylinder at the lower end of the cylindrical nozzle core and the inner wall surface of the barrel cavity of the cylindrical barrel-shaped nozzle shell, and the inverted cone at the lower end of the cylindrical nozzle core and the inverted cone inner wall at the bottom end of the barrel cavity of the cylindrical barrel-shaped nozzle shell are A conical annular atomization chamber is formed between the surfaces, an upright conical discharge spray hole connected to the conical annular atomization chamber is provided on the bottom wall of the cylindrical barrel nozzle shell, a right conical boss is provided on the middle section of the cylindrical nozzle core located on the upper part of the inverted cone, an annular gas-material mixing chamber is provided between the outer side of the middle section of the cylindrical nozzle core and the inner wall surface of the cylindrical barrel nozzle shell, the annular gas-material mixing chamber is connected to the conical annular atomization chamber through the annular gap between the cylindrical nozzle core and the cylindrical barrel nozzle shell, a compressed gas inlet is provided on the side wall of the cylindrical barrel nozzle shell, the compressed gas inlet and the feed liquid input channel are respectively connected to the annular gas-material mixing chamber, thereby forming a corn feed liquid atomization nozzle.

[0005] The invention creates a process of atomizing corn liquid. The volume of the gas-material mixing chamber and the atomizing chamber can be adjusted according to the feed amount and concentration of the corn liquid to change the pressure and flow rate of the compressed gas, adjust the injection speed and injection force of the nozzle, and ensure the atomization effect. The invention has the characteristics of novel, unique, reasonable, simple structure, easy and convenient adjustment, strong adaptability, no clogging, high efficiency, and can provide high-quality atomized corn liquid for the drying tower. The invention is particularly suitable for use in industrial production operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. A corn liquid atomizing nozzle, wherein a cylindrical nozzle core 7 is installed in the barrel cavity of a cylindrical barrel-shaped nozzle shell 3 through a threaded connection so as to be axially movable and adjustable, the lower end of the cylindrical nozzle core 7 is composed of a cylinder and an inverted cone as a whole, a liquid input channel 6 is axially opened in the center of the cylindrical nozzle core 7, the inner wall surface of the bottom wall of the barrel cavity of the cylindrical barrel-shaped nozzle shell 3 is in an inverted cone shape as a whole, and a spiral groove 8 is provided on the inverted cone inner wall surface, an annular gap is provided between the cylinder at the lower end of the cylindrical nozzle core 7 and the inner wall surface of the barrel cavity of the cylindrical barrel-shaped nozzle shell 3, and an inverted cone at the lower end of the cylindrical nozzle core 7 and the inverted cone inner wall surface of the bottom end of the barrel cavity of the cylindrical barrel-shaped nozzle shell 3 are provided. A conical annular atomizing chamber 2 is formed between the side wall surfaces, a positive conical discharge spray hole 1 connected to the conical annular atomizing chamber 2 is provided on the bottom wall of the cylindrical barrel-shaped nozzle shell 3, a right conical boss is provided on the middle section of the cylindrical nozzle core 7 located at the upper part of the inverted cone, an annular gas-material mixing chamber 4 is provided between the outer side of the middle section of the cylindrical nozzle core 7 and the inner wall surface of the cylindrical barrel-shaped nozzle shell 3, the annular gas-material mixing chamber 4 is connected to the conical annular atomizing chamber 2 through the annular gap between the cylindrical nozzle core 7 and the cylindrical barrel-shaped nozzle shell 3, a compressed gas inlet 5 is provided on the side wall of the cylindrical barrel-shaped nozzle shell 3, and the compressed gas inlet 5 and the liquid input channel 6 are respectively connected to the annular gas-material mixing chamber 4.

[0010] During operation, the corn liquid enters the annular gas-material mixing chamber 4 from the liquid input channel 6 through the high-pressure gas delivery pipe by the feed pump, and the compressed gas enters the annular gas-material mixing chamber 4 from the compressed gas inlet 5 through the high-pressure gas delivery pipe to form an annular airflow, and flows downward at high speed in the axial direction. When passing through the right conical boss of the cylindrical nozzle core 7, the airflow is compressed along the conical surface of the right conical boss to form a hollow annular airflow flowing downward. At this time, the airflow meets the corn liquid, and the corn liquid rotates at high speed under the drive of the airflow, flows downward at high speed in the axial direction, and collides with the radial side wall of the cylindrical nozzle core 7. Under the action of the impact force, the corn liquid is instantly crushed into fine corn flour particles, and the corn flour particles are driven by the airflow and the centrifugal force. It flows downward from the annular gap between the cylinder at the lower end of the cylindrical nozzle core 7 and the inner wall of the cylindrical barrel nozzle shell 3. When passing through the annular gap, the corn liquid is squeezed, and the liquid surface tension and viscosity between the particles gradually weaken, and then enters the conical annular atomization chamber 2. Under the combined action of air flow pressure, centrifugal force and corn liquid gravity, the corn flour particles rotate at high speed in the spiral groove 8 on the inner side surface of the bottom wall of the conical structure of the cylindrical barrel nozzle shell 3 and flow downward. At this point, the corn flour particles have been completely separated, and finally are ejected out in a ring shape at high speed through the upright conical discharge nozzle hole 1 on the lower end of the cylindrical barrel nozzle shell 3, and sent to the drying tower to complete the corn liquid atomization spraying and conveying operation. By rotating the cylindrical nozzle core 7 on the cylindrical barrel nozzle shell 3 and utilizing the threaded fit to adjust the axial movement of the cylindrical nozzle core 7, the volumes of the annular gas-material mixing chamber 4 and the conical annular atomizing chamber 2 can be changed, thereby changing the pressure and velocity of the compressed airflow, and further adjusting the injection velocity and injection force of the nozzle to adapt to and meet the operational requirements of different corn liquid feed amounts and concentration conditions, thereby ensuring the quality and effect of the operation.
