Description

Technical Field

[0001] The utility model specifically relates to an on-line granulation system for feed production, belonging to the technical field of feed production. Background Art

[0002] In the process of feed production, it includes processes such as crushing, batching, mixing, and granulation. Among them, before granulation, the powdery materials need to be conditioned, that is, a certain amount of steam is added to the materials, so that under the action of high temperature and high humidity, the gelatinization degree of starch increases significantly, promoting the heat denaturation of proteins in the materials. The denatured proteins are easily enzymolyzed, thereby improving the digestion and utilization rate of pellet feed. At the same time, most pathogenic bacteria (such as harmful bacteria such as Escherichia coli and Salmonella) are heat-intolerant. Using a conditioner to condition the materials at a certain temperature can kill these bacteria and ensure the feed hygiene level. In addition, the materials after high-temperature and humid heat treatment are easier to granulate and form.

[0003] Generally, at the beginning of production, in order to ensure that the materials entering the conditioner first can quickly reach the set conditioning temperature, steam is first introduced into the interlayer of the conditioner for preheating. However, often the first part of the materials entering the conditioner still cannot reach the set conditioning temperature. Therefore, this part of the materials needs to be taken out and then put back into the previous mixing process until the conditioning temperature reaches the set value, and then granulation starts. In the mixing process, generally, oil needs to be sprayed, and there is a problem of secondary addition of oil to the materials returned from the subsequent process, resulting in formula distortion and waste of oil.

[0004] In addition, for the production of pig feed, in order to prevent and control African swine fever, it is required that the conditioning temperature must reach above 85°C, that is, the feed is thoroughly sterilized. When producing pig feed, for the powdery feed with unqualified conditioning temperature at the beginning of production, if manual transfer of the head material is carried out, there is a risk of cross-contamination, and at the same time, the labor intensity of personnel is relatively large.

[0005] Although the prior art "CN205962772U Improved Granular Feed Production Equipment" processes the head material, it takes out the head material after granulation and cooling. It is a granular material and still needs to be pulverized and then returned to the granulation bin to be made, increasing the energy consumption of the granulator, cooler, and pulverizer.

[0006] Therefore, a system with low energy consumption, on-line granulation, and effective utilization of head material is needed. Summary of the Invention

[0007] To solve the problem of handling the headstock material formed during the granulation process, an on-line granulation system for feed production is proposed. In this technical solution, through the settings of the material bin to be granulated, the conditioner, the granulator, and the headstock material recovery device, etc., the orderliness, controllability, and stability of the granulation process are ensured. At the same time, on-line granulation and on-line treatment of the headstock material are realized, reducing the labor intensity; and, the headstock material is effectively recycled, improving the utilization rate of the material and reducing the risk of contamination during the production process, etc.

[0008] To achieve the above technical objectives, the following technical solutions are proposed:

[0009] An on-line granulation system for feed production, including a material bin to be granulated, a conditioner, and a granulator arranged in sequence. An upper level detector Ⅰ is provided at the upper part of the material bin to be granulated, and a lower level detector Ⅰ is provided at the lower part. The discharge port of the material bin to be granulated is connected to the feed inlet of the conditioner through a feeder.

[0010] The conditioner is connected with a steam inlet pipe. A temperature sensor is provided at the discharge port of the conditioner. A guiding three-way is provided between the discharge port of the conditioner and the feed inlet of the granulator. The temperature sensor is arranged on the front side of the process of the guiding three-way. One end of the guiding three-way is communicated with the discharge port of the conditioner, the other end is communicated with the feed inlet of the granulator, and there is also one end of the guiding three-way connected with a headstock material buffer bin.

[0011] An upper level detector Ⅱ is provided at the upper part of the headstock material buffer bin, and a lower level detector Ⅱ is provided at the lower part. A pneumatic gate is provided at the discharge port of the headstock material buffer bin. The discharge port of the headstock material buffer bin is connected to the material bin to be granulated through a return material elevator. A continuous path for headstock material recovery and reuse is formed among the guiding three-way, the headstock material buffer bin, the return material elevator, and the material bin to be granulated.

[0012] Further, a mixer is provided on the front side of the process of the material bin to be granulated. A feeding port is provided on the mixer, and the mixer is connected with an oil pipeline.

[0013] Further, the mixer is connected to the material bin to be granulated through a feeding elevator. A scraper is provided at the discharge port end of the mixer, and the discharge port of the scraper is connected to the feeding elevator.

[0014] Further, a vibrating air hammer is provided at the lower part of the material bin to be granulated.

[0015] Further, a stirring mechanism is provided inside the conditioner to improve the conditioning quality and efficiency.

[0016] Further, the on-line granulation system further includes a controller. The upper level detector Ⅰ, the lower level detector Ⅰ, the temperature sensor, the guiding three-way, the upper level detector Ⅱ, the lower level detector Ⅱ, the vibrating air hammer, and the pneumatic gate are all electrically connected to the controller. It can better realize the control of the granulation process and realize on-line granulation and on-line treatment of the headstock material.

[0017] In this technical solution, the relationships such as "upper part", "lower part", "one end", "the other end", "yet another end", "between", "front side of the process", "arranged in sequence", "above", "upper", "inside", etc. are defined according to the actual usage situation, which are common terms in this technical field and also common terms for those skilled in the art during actual use.

[0018] In the description of this technical solution, it should also be noted that unless otherwise clearly specified and limited, the terms "arranged", "provided with", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this technical solution can be understood according to specific situations.

[0019] Adopting this technical solution, the beneficial technical effects brought are as follows:

[0020] By means of the settings such as the material bin to be granulated, the conditioner, the granulator and the headstock material recovery device, etc., the present utility model ensures the orderliness, controllability and stability of the granulation process. At the same time, it realizes on-line granulation and on-line treatment of the headstock material, reducing the labor intensity; and, the headstock material is recycled in a timely and effective manner on-line, improving the utilization rate of the material and reducing the risk of being contaminated during the production process, etc.

[0021] Among them, by arranging a headstock material buffer bin at the outlet of the granulator, the headstock material is returned to the material bin to be granulated through a chute pipe and a return material elevator. On the one hand, since the powder is transported in a closed pipeline, the risk of cross-contamination is reduced, and at the same time, the labor intensity of the personnel is reduced; on the other hand, since it is returned to the material bin to be granulated, no additional grease will be added again, which can ensure that the formula is not distorted or over-crushed, etc. That is, after the headstock material with the tempering temperature not meeting the requirements at the beginning of the feed production is taken out by this on-line granulation system, it is transported to the material bin to be granulated through a return material elevator and re-tempered until the required tempering temperature is reached.

[0022] Moreover, a continuous path for headstock material recovery and reuse is formed among the guiding three-way pipe, the headstock material buffer bin, the return material elevator and the material bin to be granulated, which not only improves the stability of headstock material recovery and reuse, but also ensures the stability of the on-line granulation process.

Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] This embodiment provides an on-line pelletizing system for feed production, as Figure 1 shown, which includes a material bin 2 for pelletizing, a conditioner 3 and a pellet mill 4 arranged in sequence. A feeding level detector I 201 is provided at the upper part of the material bin 2 for pelletizing, and a discharging level detector I 202 is provided at the lower part. The discharging port of the material bin 2 for pelletizing is connected to the feeding port of the conditioner 3. The conditioner 3 is connected with a steam inlet pipe. A temperature sensor 7 is provided at the discharging port of the conditioner 3. A guiding three-way pipe 8 is provided between the discharging port of the conditioner 3 and the feeding port of the pellet mill 4. The temperature sensor 7 is arranged on the process front side of the guiding three-way pipe 8. One end of the guiding three-way pipe 8 is communicated with the discharging port of the conditioner 3, the other end of the guiding three-way pipe 8 is communicated with the feeding port of the pellet mill 4, and the guiding three-way pipe 8 also has one end connected to a buffer bin 9 for head material;

[0028] A feeding level detector II 901 is provided at the upper part of the buffer bin 9 for head material, and a discharging level detector II 902 is provided at the lower part. Preferably, a pneumatic gate 10 is provided at the discharging port of the buffer bin 9 for head material. The discharging port of the buffer bin 9 for head material is connected to the material bin 2 for pelletizing through a return material elevator 11. A continuous path for head material recovery and reuse is formed among the guiding three-way pipe 8, the buffer bin 9 for head material, the return material elevator 11 and the material bin 2 for pelletizing.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, this embodiment further defines the layout and structure of the material bin 2 for pelletizing to further illustrate this technical solution.

[0031] A mixer 1 is provided on the front side of the process of the pelletizing material bin 2. A feeding port 101 is provided on the mixer 1, and an oil pipeline 12 is connected to the mixer 1. The mixer 1 is connected to the pelletizing material bin 2 through a feeding elevator 13. A scraper conveyor 14 is provided at the discharge port end of the mixer 1, and the discharge port of the scraper conveyor 14 is connected to the feeding elevator 13. Therefore, in this technical solution, the recycled head material is directly recycled to the pelletizing material bin 2, rather than the mixer 1 or the crusher, etc., to ensure that the feed formula is not distorted or over-crushed, etc.

[0032] In addition, a vibrating air hammer 203 is provided at the lower part of the pelletizing material bin 2. Among them, when the material in the pelletizing bin is not flowing smoothly, the vibrating air hammer 203 can be started to ensure smooth feeding.

[0033] Example 3

[0034] On the basis of Examples 1-2, this example further defines the layout and structure of the conditioner 3 to further illustrate this technical solution.

[0035] The feed inlet of the conditioner 3 is connected to the discharge port of the pelletizing material bin 2 through a feeder 5, which ensures that the material in the pelletizing material bin 2 is fed into the conditioner 3 orderly, controllably and stably, and improves the orderliness of material transfer.

[0036] A stirring mechanism 301 is provided inside the conditioner 3 to improve the conditioning quality and efficiency.

[0037] Example 4

[0038] On the basis of Examples 1-3, in this example, in order to improve the automatic control and on-line performance of the pelletizing process, it is further defined that the on-line pelletizing system further includes a controller, and the upper level detector I 201, the lower level detector I 202, the temperature sensor 7, the guiding three-way 8, the upper level detector II 901, the lower level detector II 902, the vibrating air hammer 203 and the pneumatic gate 10 are all electrically connected to the controller.

[0039] Example 5

[0040] Based on Examples 1-4, provided: An on-line processing process for feed head material, a head material buffer bin 9 and a return material elevator 11 are arranged at the discharge port of the pelletizing machine 4 in the existing feed pelletizing section. As Figure 1 shown, the specific process is as follows:

[0041] I. The materials used for feed production are crushed, mixed, and various oils are added during mixing. Then, the mixed powdery materials are lifted and enter the pelletizing bin.

[0042] II. The material bin 2 to be granulated is equipped with high and low level sensors (upper level detector I 201, lower level detector I 202) and a vibrating air hammer 203. When the upper level detector I 201 alarms, the feeding in the previous process section is stopped; when the lower level detector I 202 alarms, the central control personnel are reminded to replenish the materials in the bin in time; when the materials in the material bin 2 to be granulated are not flowing smoothly, the vibrating air hammer 203 can be started to ensure smooth feeding.

[0043] III. The powdery materials enter the conditioner 3 through the feeder 5, and steam is introduced into the conditioner 3 to enable the powdery materials to come into full contact and mix with the steam. For pig feed, generally, the conditioning temperature is required to be above 85 °C. On the one hand, starch gelatinization is beneficial to digestion, and at the same time, it plays a role in sterilization and disinfection to avoid African swine fever.

[0044] IV. The conditioning temperature is detected by the temperature sensor 7 set at the outlet of the conditioner 3. When starting up, the material temperature is relatively low. The guide material three-way pipe 8 is connected to the headstock buffer bin 9 (the guide material three-way pipe 8 is turned to position ②), and the powder materials enter the headstock buffer bin 9 through the chute. After the upper level detector II 901 is triggered, the return material elevator 11 and the pneumatic gate 10 are started in sequence to lift and convey the materials in the headstock to the bin to be granulated; when the lower level detector II 902 is triggered, through time delay setting, it is ensured that the materials in the headstock buffer bin 9 are discharged completely and lifted into the material bin 2 to be granulated; then, the pneumatic gate 10 and the return material elevator 11 are closed and stopped in sequence.

[0045] When the conditioning temperature reaches the set value, the guide material three-way pipe 8 is connected to the granulator 4 (the guide material three-way pipe 8 is turned to position ①). At this time, the powder materials enter the chamber of the granulator 4 for granulation. After granulation, it enters the next process.

[0046] Among them, when the granulator 4 is just started up, for the headstock materials that have not reached the conditioning temperature, they are returned to the bin to be granulated through the on-line treatment process for re-conditioning. When the conditioning temperature is reached, the powder materials are then fed into the granulation chamber for granulation. Since the headstock materials are subjected to on-line treatment in a closed pipeline, on the one hand, the risk of cross-contamination of materials is reduced, and on the other hand, the labor intensity of personnel is reduced.
