Description

Technical Field

[0001] The utility model relates to the technical field of medicine processing, in particular to a boiling granulator which can make materials perform cyclonic motion. Background Art

[0002] Fluidizing dryer is a drying equipment that heats the air through a heat exchanger to form hot air. The clean hot air is distributed through a valve plate into the body of the fluidizing dryer. The wet material that enters the body of the dryer from the feeder is boiled by the hot air. Since the hot air is in extensive contact with the material, the heat and mass transfer process is increased, so the material can be dried in a shorter time. Fluidizing dryer can be used for drying pharmaceuticals, chemical raw materials, food, grain processing, and feed.

[0003] At present, the airflow distribution plate of the silo of the existing boiling granulator is a perforated mesh plate, and the direction of the holes is perpendicular to the bottom plate. When the airflow enters from the bottom, the airflow direction is perpendicular to the hole plate and upward, blowing up the material to achieve a boiling effect. This method has high requirements on the strength of the airflow, which makes it easy for the material to stick to the filter bag. The filter bag cannot maintain a high filtration efficiency for a long time. At the same time, the use range of the airflow is small, which causes the granulator to require a longer working time. Utility Model Content

[0004] The utility model aims to solve the above-mentioned shortcomings of the prior art and provides a boiling granulator which can make materials move in a cyclonic manner to solve the above-mentioned problems.

[0005] The utility model adopts a technical solution to solve the technical problem: the boiling granulator capable of making materials perform cyclonic motion comprises a bottom bin, a material bin, a main bin and a top bin; the air inlet end of the bottom bin is externally connected with an air inlet pipe; a spoiler located above the air inlet end is arranged in the bottom bin; a cyclonic distribution plate located above the spoiler is arranged at the air inlet end of the material bin; the spoiler can divert the airflow into several streams when the airflow passes through, and ensure that each diverted airflow can be directly sent to the cyclonic distribution plate from all sides; the cyclonic distribution plate makes the airflow present a state of rotational motion when the airflow passes through, and allows the material to be driven to perform cyclonic boiling motion by the rotational motion of the airflow.

[0006] For further improvement, a mounting plate which does not hinder the airflow passing through the air intake end is provided at the air intake end of the bottom bin, a socket is provided at the center position of the mounting plate, a mounting rod is provided in the socket, and the spoiler is provided on the mounting rod.

[0008] For further improvement, an external frame is provided outside the cyclone distribution plate for positioning the cyclone distribution plate at the air inlet of the silo, and the external frame is arranged at the air inlet end of the silo by means of bolts.

[0009] Further improvement, the cyclone distribution plate includes a spliced ​​inner plate and a plurality of spliced ​​outer plates arranged on the outer peripheral surface of the spliced ​​inner plate and distributed along its circumferential direction, and the spliced ​​inner plate and the spliced ​​outer plate are both provided with a plurality of second through holes inclined in the same direction.

[0010] Further improvement, the inclined direction of the second through hole and the tangent direction inwardly present an angle of 10°-15°.

[0011] The beneficial effects of the utility model are:

[0012] The utility model utilizes a spoiler to split the airflow, so that the flow rate and flow state of each split airflow are balanced, not only from the middle one, but also can expand the use range of the airflow. The cyclone distribution plate makes the airflow passing through it rotate, and the rotational motion makes the airflow and temperature more uniform. Only a small air volume is needed to achieve a good boiling effect, and it is difficult to bed. The granulation effect is more uniform and denser, and the boiling height of the material is reduced, and the material is less likely to stick to the filter bag. The filter bag can maintain a high filtration efficiency for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

The cyclone distribution plate 4 makes the airflow present a state of rotational motion when the airflow passes through, and allows the rotational motion of the airflow to drive the material to perform cyclonic boiling motion. The principle of the utility model is that the airflow is firstly diverted by the spoiler 3, so that the flow rate and flow state of each diverted airflow are balanced, not just from the middle one, but also can expand the use range of the airflow, the cyclone distribution plate 4 makes the airflow passing through it rotate, the rotational motion makes the airflow and temperature more uniform, only a small amount of air is needed to achieve a good boiling effect, and it is difficult to bed, the granulation effect is more uniform and denser, and the boiling height of the material is reduced, the material is less likely to stick to the filter bag, and the filter bag can maintain a high filtration efficiency for a long time.

Such a configuration enables the spoiler 3 to be located at the center position of the bottom bin 11, so that the airflow can be evenly dispersed to various positions after being diverted by it, and it is convenient to assemble and disassemble, that is, the mounting rod 511 provided on the spoiler 3 can be inserted into the socket 51, and the area of ​​the mounting plate 5 only needs to meet the installation requirements of the socket 51. This method will not hinder the airflow from entering the bottom bin 11, and the two ends of the mounting plate 5 are fixed to the inner wall of the air inlet end of the bottom bin 11 by welding.

[0020] The spoiler 3 includes a mounting base plate 31, and a baffle 32 arranged on the outer peripheral surface of the mounting base plate 31 and distributed along the circumferential direction thereof. The mounting base plate 31 is arranged on the mounting rod 511, and the outer diameter of the baffle 32 gradually increases from bottom to top, and a plurality of first through holes 321 perpendicular to the mounting base plate 31 are arranged on the outer peripheral surface of the baffle 32, that is, the baffle 32 is configured in a conical shape by virtue of the setting that the outer diameter is small at the bottom and large at the top after it is in a circle, so that the area that the spoiler 3 can cover is increased, and a plurality of first through holes 321 are used to divert the airflow that rushes straight in, so as to ensure that the flow rate and flow state of each diverted airflow are balanced, so that the temperature acting on the material is more uniform.

[0021] An external frame 6 is provided outside the cyclone distribution plate 4 for positioning the cyclone distribution plate 4 at the air inlet of the silo 12. The external frame 6 is set at the air inlet end of the silo 12 by bolts.

The spliced ​​inner plate 41 and the spliced ​​outer plate 42 are both provided with a plurality of second through holes 7 inclined in the same direction. The cyclone distribution plate 4 is composed of the spliced ​​inner plate 41 and the plurality of spliced ​​outer plates 42, and the spliced ​​inner plate 41 and the plurality of spliced ​​outer plates 42 are welded together, so that it can be ensured that the inclination direction of the second through holes 7 on each spliced ​​outer plate 42 is in one direction, i.e., clockwise or counterclockwise around the circumference, which is also convenient for molding during processing.

[0023] The inclination direction of the second through hole 7 and the tangent direction are at an angle of 10°-15° inwardly, and the angle can be selected within the range of 10°-15°, that is, when the second through hole 7 is formed on the spliced ​​outer panel 42, the angle presented by the second through hole 7 is not limited to a single angle, which reduces the processing requirements, and such an angle also enables the airflow to ensure the effectiveness and efficiency of this motion state when it is in a cyclonic rotational motion.
