The feed spraying system comprises a spraying tank, a material conveying device 3 and a spraying device 4.

The spraying device 4 is used for mixing the additive and the inert carrier and forming a suspension and spraying the suspension containing the additive components onto the feed. In this example, for ease of description, the suspension sprayed onto the feed is generally referred to as an additive.

The number of the spraying tanks is two, and the two spraying tanks are a first spraying tank 1 and a second spraying tank 2 respectively. The spraying tank is provided with a feed inlet for feed and a discharge outlet for feed and discharge. The material conveying device 3 is arranged between the two spraying tanks, the first spraying tank 1 is located at the upstream of the material conveying device 3 along the conveying direction of feed, and the second spraying tank 2 is located at the downstream of the material conveying device 3, so that the feed in the first spraying tank 1 can be conveyed to the second spraying tank 2 through the material conveying device 3. Specifically, one end of the material conveying device 3 is connected with a discharge port of the first spraying tank 1, and the other end of the material conveying device 3 is connected with a feed port of the second spraying tank 2.

The two spraying devices 4 are respectively connected with the two spraying tanks, and the two spraying devices 4 respectively spray the feed in the two spraying tanks. The spraying device 4 comprises a material liquid tank, an air compressor 43 and an air-liquid spray head 44. The feed liquid jar is used for storing and mixing the additive, and feed liquid jar and air compressor 43 all are connected with gas-liquid shower nozzle 44 through pipeline 8. The air compressor 43 is used for compressing external air and delivering the compressed air to the gas-liquid spray head 44, and the gas-liquid spray head 44 is used for mixing and atomizing the compressed air from the air compressor 43 and the additive from the feed liquid tank and spraying the mixture onto feed so as to realize the spraying treatment of the feed. The feed is sprayed by adopting the gas-liquid spray head 44, the additive and the compressed air are mixed and sprayed to be in an atomized state, the spraying range is wider, the additive can be uniformly sprayed on the feed, and the absorption of the additive by the feed is facilitated.

Correspondingly, the number of the feed liquid tanks is two, and the two feed liquid tanks are a first feed liquid tank 41 and a second feed liquid tank 42 respectively. The gas-liquid spray head 44 is disposed on the side wall of the spray can so that the gas-liquid spray head 44 can spray the additive to the feed in the spray can.

Specifically, the first spray can 1 has a cylindrical cavity structure, and the interior of the first spray can 1 has a storage chamber 11 for containing feed. The pan feeding mouth of first spraying jar 1 is provided with feeder hopper 13, and feeder hopper 13 and the storage chamber 11 of first spraying jar 1 communicate. During feeding, feed is fed into the first spray tank 1 through the feed hopper 13. The feeder hopper 13 is located at the top of the first spray can 1, and the discharge port of the first spray can 1 is located at the bottom of the first spray can 1. A first stirrer 12 is arranged in the storage cavity 11 of the first spraying tank 1, and the first stirrer 12 is used for stirring the feed in the storage cavity 11. A plurality of gas-liquid spray nozzles 44 are provided on the side wall of the first spray tank 1, and the plurality of gas-liquid spray nozzles 44 are distributed at intervals along the circumferential direction of the first spray tank 1. The first material liquid tank 41 is connected with a gas-liquid spray nozzle 44 on the first spraying tank 1 through a pipeline 8, and the air compressor 43 is correspondingly connected with the gas-liquid spray nozzle 44 on the first spraying tank 1 through the pipeline 8. The conduit 8 is provided with a high pressure pump 46 and a valve 47 at the end near the first stock solution tank 41, the high pressure pump 46 being used to drive the flow of additive from the first stock solution tank 41 along the conduit 8 towards the gas-liquid spray head 44. The valve 47 is used to control the on-off of the pipe 8. The gas-liquid spray head 44 is located at the upper part of the first spray tank 1, and the gas-liquid spray head 44 is disposed adjacent to the feed inlet. During the spraying process, feed falls from the feed hopper 13 and enters the storage chamber 11 through the inlet of the first spray tank 1. During the feed fall, the plurality of gas-liquid spray heads 44 spray the additive toward the feed. The simultaneous spraying of the additive from the periphery of the feed by the plurality of gas-liquid spray heads 44 advantageously allows the additive to be uniformly sprayed on the feed. Meanwhile, the feed is sprayed in the falling process of the feed, the feed rolls and collides in the air, and the gap between the feeds is continuously changed, so that the additives are uniformly sprayed on the feed. The feed sprayed with the additive falls down and is deposited in the storage chamber 11, and the first stirrer 12 stirs and mixes the feed in the storage chamber 11 so that the additive and the feed are sufficiently mixed.

The second spray can 2 has a cylindrical cavity structure, and a storage cavity 11 for accommodating feed is formed in the second spray can 2. The feed inlet of the second spraying tank 2 is connected with the discharge outlet of the first spraying tank 1 through a feed conveying device 3, so that the feed in the first spraying tank 1 is conveyed into the second spraying tank 2 through the feed conveying device 3. The feed inlet of the second spray tank 2 is located at the top of the second spray tank 2 so that feed falls from the top of the second spray tank 2 into the storage chamber 11. A plurality of gas-liquid spray nozzles 44 are arranged on the side wall of the second spray tank 2, and the plurality of gas-liquid spray nozzles 44 are distributed at intervals along the circumferential direction of the second spray tank 2. The second material liquid tank 42 is connected with a gas-liquid spray nozzle 44 on the second spraying tank 2 through a pipeline 8, and the air compressor 43 is correspondingly connected with the gas-liquid spray nozzle 44 on the second spraying tank 2 through the pipeline 8. The conduit 8 is provided with a high pressure pump 46 and a valve 47 at the end adjacent the second charge tank 42, the high pressure pump 46 being used to drive the flow of additive from the second charge tank 42 along the conduit 8 towards the gas-liquid spray head 44. The valve 47 is used to control the on-off of the pipe 8. A gas-liquid spray head 44 is located at the upper part of the second spray tank 2, the gas-liquid spray head 44 being arranged adjacent to the feed opening. During the spraying process, the feed falls from the feed inlet of the second spray tank 2, and during the feed falling process, the plurality of gas-liquid spray heads 44 spray the additive toward the feed. The simultaneous spraying of the additive from the periphery of the feed by the plurality of gas-liquid spray heads 44 advantageously allows the additive to be uniformly sprayed on the feed. Meanwhile, the feed is sprayed in the falling process of the feed, the feed rolls and collides in the air, and the gap between the feeds is continuously changed, so that the additives are uniformly sprayed on the feed. The feed after spraying the additive falls and is deposited in the storage chamber 11 of the second spray tank 2. Finally, the feed is discharged through the discharge port 21 on the second spray can 2, and the spray treatment of the feed is completed.

It will be appreciated that the feed in the feed spray system is sprayed twice, i.e. a first spray in the first spray tank 1 and a second spray in the second spray tank 2. Because the feed is compact in texture, the absorption speed of the feed to the additive is slower after the additive is sprayed on the surface of the feed. After the feed is sprayed for the first time, one part of the additive on the surface of the feed gradually permeates into the feed, and the other part of the additive is lost in the process of mixing the feed and in the process of contacting with equipment. Meanwhile, the additive is mainly adsorbed on the surface layer of the feed, so that the surface layer of the feed falls off in the falling process and the conveying process of the feed, and the content of the additive in the feed can be reduced. Thus, the feed after the first spraying treatment is fed into the second spraying tank 2 through the feeding device 3, and the feed is subjected to the second spraying treatment in the second spraying tank 2. The additive sprayed for the first time is permeated into the inner layer of the feed, and the additive sprayed for the second time is adsorbed on the surface layer of the feed again and gradually permeated inwards. The feed with the surface layer falling off can be sprayed with the additive again to increase the content of the additive in the feed. The feed spraying system is used for spraying the feed twice, so that the additive permeates into the feed twice. Compared with the process of spraying once, the method can avoid the loss of the additive sprayed on the surface of the feed due to the fact that the additive cannot quickly permeate into the feed, further ensure the content of the additive in the feed and ensure the processing quality of the feed.

Optionally, the first agitator 12 comprises a motor, a connecting shaft and an agitating blade. The motor is installed in the bottom of first spraying jar 1, and the connecting axle sets up with first spraying jar 1 is coaxial, and the output transmission of connecting axle and motor is connected. The stirring vane is a plurality of, and a plurality of stirring vane are along the length direction interval distribution of connecting axle. The free ends of the stirring vanes extend towards the chamber wall of the storage chamber 11. The motor is used for driving the connecting shaft to rotate so as to realize stirring treatment on the feed in the storage cavity 11.

Optionally, a screen 22 is arranged in the storage cavity 11 of the second spraying tank 2, and the screen 22 is used for filtering powder and scraps of the feed falling off due to collision in the conveying process so as to obtain a granular feed finished product with uniform size. The screen 22 is obliquely disposed in the storage chamber 11 and partitions the storage chamber 11 into an upper chamber and a lower chamber. The upper chamber is located above the lower chamber. The feed is deposited in the upper chamber after falling from the feed inlet of the second spray tank 2. Under the filtering action of the screen 22, the powder and the scraps fall into a lower chamber through holes on the screen 22, and the lower chamber collects the powder and the scraps. A discharge hole 23 is arranged on the wall of the lower chamber, and a material removing door is arranged on the upper cover of the discharge hole 23. When the powder and the scraps in the lower cavity are deposited to a certain amount, the powder and the scraps in the lower cavity can be removed through the discharge hole 23. For the convenience of discharging powder and scraps in the lower cavity, the bottom surface of the lower cavity is curved, the discharge hole 23 is arranged on the bottom surface of the lower cavity, and the discharge hole 23 is positioned at the lowest part of the lower cavity so as to be beneficial to discharging the powder and scraps through the discharge hole 23. The discharge port 21 is provided at the lowest position of the upper chamber, and the fodder falls onto the screen 22 and slides down the screen 22, and finally is discharged from the discharge port 21.

The feed in the upper cavity is subjected to the second spraying treatment, so that the surface of the feed is more moist. To avoid that the wet powder and the scraps block the holes of the screen 22, an air pipe is further arranged in the lower cavity, and hot air is blown to the screen 22 by the air pipe so as to avoid that the wet powder and the scraps are adhered to the screen 22. The air pipe is parallel to the screen 22 in the blowing direction, and is subjected to one-time blowing treatment at certain intervals, so that powder and scraps are prevented from falling smoothly.

Optionally, two air compressors 43 are provided, and the two air compressors 43 are respectively connected with the gas-liquid spray heads 44 on the two spraying tanks. A cooler 45 is further arranged between the air compressor 43 and the gas-liquid spray nozzle 44, the cooler 45 comprises a plurality of heat exchange tube groups, and the heat exchange tube groups are utilized to exchange heat with the compressed air and cool the compressed air. It is understood that some of the additive components (e.g., vitamins, enzyme preparations) are heat sensitive. The temperature of the processed granular feed is high, and the high temperature can cause the loss of additives in the feed. The compressed air is cooled by the cooler 45, so that the compressed air with lower temperature can play a role in cooling the feed, so that the feed is synchronously cooled during spraying treatment, the additive is prevented from being lost due to high temperature, and the processing quality of the feed is ensured.

Alternatively, the first material liquid tank 41 and the second material liquid tank 42 are identical in structure. A liquid storage chamber 410 for containing an additive is provided in each of the first material liquid tank 41 and the second material liquid tank 42. A second stirrer 411 for stirring the additive is provided in the liquid storage chamber 410. The structure and function of the second pulsator 411 are the same as those of the first pulsator 12, and will not be described again here. The top and bottom of the material liquid tanks are respectively provided with a feed inlet and a discharge outlet, the feed inlets of the first material liquid tank 41 and the second material liquid tank 42 are respectively provided with a raw material bin 6, and raw materials (such as vitamins, enzyme preparations, inert carriers and the like) of the additives are added into the corresponding liquid storage cavities 410 through the raw material bin 6. In practical application, a plurality of raw material bins 6 can be arranged, and a plurality of additive raw materials are respectively added by using the plurality of raw material bins 6. For example, when the additive raw materials are three, three raw material bins 6 are provided correspondingly, and each raw material bin 6 is used for containing one additive raw material. It is also possible to divide the interior of the raw material bin 6 into a plurality of compartments, each compartment containing a respective additive raw material. A meter 7 is arranged between the raw material bin 6 and the feed liquid tank, and the meter 7 is used for metering the added raw materials so as to meet the requirement that the raw material component ratio of the additive in the liquid storage cavity 410 meets the technological index.

Optionally, referring to fig. 2, the feed spraying system further comprises a temporary storage tank 5, the temporary storage tank 5 being used for temporarily storing feed.

Correspondingly, the number of the material conveying devices 3 is two, the top and the bottom of the temporary storage tank 5 are respectively provided with a material inlet and a material outlet, and the material inlet and the material outlet of the temporary storage tank 5 are respectively connected with the two spraying tanks through the two material conveying devices 3. Specifically, the discharge gate of first spraying jar 1 passes through the feed mechanism 3 and is connected with the pan feeding mouth that faces storage tank 5, and the pan feeding mouth of second spraying jar 2 passes through the feed mechanism 3 and is connected with the discharge gate that faces storage tank 5. The feed subjected to the first spraying treatment by the first spraying tank 1 is conveyed into the temporary storage tank 5 through the conveying device 3. The temporary storage tank 5 stores the feed so that the additive sufficiently permeates into the feed. A discharge hole of the temporary storage tank 5 is provided with a control valve, and the control valve is connected with a timer. When the feed is kept stand in the temporary storage tank 5 for a certain time, the control valve is opened, and the feed in the temporary storage tank 5 is conveyed into the second spraying tank 2 through the conveying device 3 and is subjected to second spraying treatment.

In practical application, two spraying tanks can be used to spray the feed twice respectively, and the additive sprayed by the spraying device 4 to the feed is the same. Different additives can also be stored in the two feed liquid tanks, namely, two different additives are sprayed on the feed. As one additive is fully absorbed by the feed after the first spraying treatment, enough additive can be ensured to be attached to the surface layer of the feed during the second spraying, so that the content of the two additives in the feed is ensured, and the processing quality of the feed is ensured.

The remarkable effects of this embodiment are: through setting up two spraying jars, utilize two spraying jars to carry out twice spraying to the fodder and handle for the additive divides two to permeate to the fodder inside.
