Detailed Description
Examples:
the utility model is further elucidated below in conjunction with the accompanying drawings.
The directions related in the specification are all based on the directions of the feed pellet rapid drying and cooling device in normal operation, are not limited to the directions of storage and transportation, and only represent relative positional relationship and not absolute positional relationship.
As shown in fig. 1-3, the rapid drying and cooling device for the feed pellets comprises a cooling tank 1 and a dust removal bin 2, wherein the bottom of the cooling tank 1 is communicated with the dust removal bin 2, the cooling tank 1 comprises a first bin body 11 and a second bin body 12, the first bin body 11 is positioned in the second bin body 12, and a cooling coil 17 arranged around the first bin body 11 is installed in the second bin body 12; a power motor 13 and a feed inlet 14 are arranged at the top of the cooling tank 1, a rotating shaft 15 is vertically arranged in the first bin 11, one end of the rotating shaft 15 is in power connection with the power motor 13, and a plurality of stirring blades 16 are arranged on the side wall of the rotating shaft 15; the feed inlet 14 is communicated with the first bin 11; after the high temperature feed pellets reach the first housing 11, the cooling coil 17 is fed with a cooling medium, and the low temperature cooling medium exchanges heat with the high Wen Siliao pellets in the first housing 11. At this time, the cooling rate of the feed pellets in the first housing 11 near the inner wall is high, and the cooling rate of the feed pellets in the center region is low, which results in uneven heat and cold of the feed pellets near the inner wall, and breakage of the feed pellets. In order to prevent the problem, the scheme introduces the power motor 13 and the rotating shaft 15, the power motor 13 drives the rotating shaft 15 to rotate, and at the same time, the rotating shaft 15 drives the stirring fan blades 16 to rotate. Under the drive of stirring flabellum 16, the fodder granule in the first storehouse body 11 evenly mixes for the fodder granule in different regions can evenly dispel the heat.
Although the above steps reduce the likelihood of feed pellet breakage, there still occurs some breakage of the feed pellets into powder. Therefore, we need to filter this part of the powder. For this purpose, a filter bed 21 is obliquely arranged in the dust removal bin 2, a filter screen 22 is arranged at the bottom of the filter bed 21, one end of the filter bed 21 is arranged opposite to the cooling tank 1, a discharging channel 23 is arranged at one end of the dust removal bin 2 far away from the cooling tank 1, and the discharging channel 23 is connected with one end of the filter bed 21; the bottom of the dust removal bin 2 is provided with a collection bin 24. The cooled feed pellets fall onto the filter bed 21, and the feed pellets falling onto the filter bed 21 roll toward one end of the filter bed 21 under the influence of gravity of the feed pellets themselves because the filter bed 21 is inclined. In this process, the powder passes through the screen 22 and falls into the collection bin 24, due to the very small particle size of the powder, thereby completing the screening of the feed pellets.
To try to filter the powder, we need to lengthen the time that the feed particles are on the filter bed 21. The desire to extend the time that the feed particles are on the filter bed 21 is to extend the width of the filter bed 21, but this greatly increases the footprint of the filter bed 21. Secondly, the inclination angle of the filter bed 21 is reduced, which reduces the moving speed of the feed particles and thus increases the time the feed particles are on the filter bed 21. For this purpose, the angle between the filter bed 21 and the horizontal plane is a, and a is more than 0 DEG and less than or equal to 30 deg. Through several trials by the staff, we found that the rolling speed of the feed particles on the filter bed 21 was most suitable when a=15°.
In order to accelerate the filtration speed of powder, the top of dust removal storehouse 2 is installed high-pressure air package 3, install high-pressure air flue 31 between filter bed 21 and the high-pressure air package 3, a plurality of high-pressure air vents 32 have been seted up to the side of high-pressure air flue 31 towards filter bed 21. The high-pressure gas bag 3 is filled with low-temperature dry inert gas, and the inert gas reaches the high-pressure air port 32 along the high-pressure air passage 31 and then exits toward the filter bed 21 along the high-pressure air port 32. The high flow rate of inert gas passes through the screen 22 and carries the dust away to the collection bin 24. Therefore, the design solves the problem of dust filtration and performs secondary cooling on the feed particles, so that the temperature of the feed particles meets the standard.
The high flow rate of inert gas, while carrying away the powder, impacts the powder when it comes into contact with the sieve 22, causing the powder to flood the dust bin 2. In order to accelerate the powder guiding speed, a filter mechanism 4 is mounted at the bottom of the collecting bin 24, the filter mechanism 4 comprises a filter bag 41 and an exhaust fan 42, and an opening of the filter bag 41 is communicated with the bottom of the collecting bin 24. Under the guidance of the exhaust fan 42, the powder and the inert gas are rapidly introduced into the collection bin 24 and then into the filter bag 41, and then the powder is intercepted and collected by the filter bag 41, and the inert gas is discharged to the outside.
In order to prevent the impacted powder from reaching the outside to form dust pollution, a sealing soft net 25 is arranged between the filter bed 21 and the discharging channel 23.
In order to control the speed of feed particles entering the dust removal bin 2 and avoid influencing the dust removal effect, a feeding channel 5 is arranged between the cooling tank 1 and the dust removal bin 2, a connecting shaft 51 is vertically arranged in the feeding channel 5, one end of the connecting shaft 51 is connected with the rotating shaft 15, and a spiral blade 52 is arranged on the outer wall of the connecting shaft 51. The design makes driving motor both can drive axis of rotation 15 and stirring vane to stir the fodder granule in the first storehouse body 11, has driven connecting axle 51 and helical blade 52 again, controls the unloading speed of fodder granule.
In this scheme, the both ends of cooling coil 17 are inlet and liquid outlet respectively for guarantee the business turn over of coolant.
In summary, the device has the following advantages: firstly, the feed particles are cooled in the first bin body 11 and then sent to the dust removal bin 2, and the powder in the feed particles is separated out with the aid of the filter bed 21, so that the final quality of the feed is improved. Secondly, the powder separation is assisted by the high-pressure air bag, and the feed particles are cooled secondarily, so that the problem of poor quality of the final product caused by cooling of the feed particles is avoided. Thirdly, the powder is guided to be separated by the filtering mechanism 4, and then the powder is fixed by the filter bag 41, so that the subsequent powder can be reused conveniently.
The foregoing describes in detail specific embodiments of the present utility model, which are the best modes for carrying out the utility model and are not intended to limit the scope of the utility model. Equivalent modifications and substitutions of this utility model will occur to those skilled in the art, and it is intended to be within the scope of the present utility model.
