Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a low-impurity weaned piglet feed processing device, comprising a discharge pipe 1, a material separation device 2, a connecting pipe 3, a feeder 4, an isolation net 6, a dust collector 7, a second air lock 11, and a third air lock 12; the discharge pipe 1 is vertically arranged, the upper end of the discharge pipe 1 is connected to the feeder 4, the feeder 4 is arranged at the upper end of the discharge pipe 1, a hopper 8 is arranged on the feed inlet above the feeder 4, the lower end of the discharge pipe 1 is connected to the third air lock 12, the third air lock 12 is arranged at the lower end of the discharge pipe 1, the two ends of the connecting pipe 3 are respectively connected to the discharge pipe 1 and the material separation device 2, the connecting pipe 3 is inclined, and the connecting pipe 3 and the material separation device 2 are connected. The horizontal height of the connected port is lower than the horizontal height of the port connecting the connecting pipe 3 and the discharge pipe 1; an air vent 5 is arranged on the pipe wall of the discharge pipe 1, and outside air can enter the discharge pipe 1 from the air vent 5; the air vent 5 is directly opposite to the port connecting the connecting pipe 3 and the discharge pipe 1, and the horizontal height area range of the air vent 5 covers the horizontal height area range of the port connecting the connecting pipe 3 and the discharge pipe 1; the air vent 5 and the port connecting the connecting pipe 3 and the discharge pipe 1 are respectively located on opposite sides of the discharge pipe 1; the isolation net 6 is arranged on the air vent 5; the lower end of the material separation device 2 is connected to the second air shut-off device 11, and the upper end of the material separation device 2 is connected to the air inlet of the dust collector 7 through the air duct 13.

[0027] In order to improve the impurity removal efficiency, the discharge pipe 1 can be configured as a square pipe, that is, a pipe with a square cross section.

[0028] During the impurity removal process, a material separation device 2 of a suitable type or specification can be selected according to the actual situation of the site to complete the separation of the gas-solid system;

[0029] The function of the material separation device 2 is to separate the airflow and the impurity-free material entering therein and discharge them from the material separation device 2, thereby completing the separation of the gas-solid system;

[0030] The material separation device 2 may be an expanded cavity shell; the material separation device 2 may also be an expanded cavity shell with a horizontal cross section that is a polygon (such as a quadrilateral, hexagon, octagon, etc.) greater than or equal to four sides; the material separation device 2 is arranged vertically;

[0031] In order to further reduce processing costs and better improve the impurity removal effect of feed, the material separation device 2 uses a cyclone separator (a cyclone separator is a device used for separation of gas-solid systems).

[0032] In order to improve the impurity removal efficiency, the connecting pipe 3 can be set as a square pipe, that is, a pipe with a square cross section.

[0033] In order to control the material flow more stably, make the material flow state better, and further improve the impurity removal efficiency, the feeder 4 can be set as an impeller feeder.

[0034] On the basis of ensuring the impurity removal effect, in order to enable the feeder 4 to flexibly adapt to a wider range of process conditions, the feeder 4 is frequency-controlled.

[0035] In order to improve the recovery rate of feed during processing and reduce material loss, the dust collector 7 can be configured as a cylindrical pulse bag dust collector.

[0036] On the basis of ensuring the impurity removal effect, in order to allow the air volume to be flexibly adjusted to adapt to a wider range of process requirements, the fan 9 of the dust collector 7 is frequency-controlled.

[0037] When the low-impurity weaned piglet feed processing device is used, the dust collector 7 is started, and the fan 9 of the dust collector 7 and the first-off blower 10 of the dust collector 7 are both started to work; the fan 9 of the dust collector 7 can be flexibly adjusted to an appropriate speed according to the process parameter requirements in the production and processing of weaned piglet feed, so that the suction volume of the fan 9 is in an optimal impurity removal effect state; due to the suction effect of the fan 9 of the dust collector 7, the outside air flows into the discharge pipe 1 from the vent 5 on the pipe wall of the discharge pipe 1, and the isolation net 6 serves to isolate impurities in the air from entering the discharge pipe 1 with the air flow. If there are impurities in the air flow, they will not be able to pass through the isolation net 6, and thus cannot enter the discharge pipe 1, thereby reducing the chance of impurities entering the material with the air flow; further, the air flow flows into the port where the connecting pipe 3 is connected to the discharge pipe 1, and further, the air flow enters the connecting pipe 3.

[0038] Start the second air shutoff 11 and the third air shutoff 12; start the feeder 4, and flexibly adjust the rotation speed of the feeder 4 according to the process parameter requirements in the production and processing of weaned piglet feed, so that the instant feeding amount of the feeder 4 is in the best impurity removal effect state.

[0039] The weaned piglet feed is introduced into the hopper 8, and the weaned piglet feed in the hopper 8 is stably and evenly fed into the upper end inlet of the discharge pipe 1 through the feeder 4, and the material falls stably and evenly in the discharge pipe 1. When the material flows through the vent 5, it is affected by the airflow flowing into the vent 5. The weaned piglet feed is powdery and light and will enter the connecting pipe 3 with the airflow. The impurities (stones, small iron parts, etc.) mixed in the weaned piglet feed will continue to fall in the discharge pipe 1 because they are heavier, so that the impurities such as stones and small iron parts in the weaned piglet feed that are not conducive to ensuring better digestion of weaned piglets and will cause hidden dangers to ensuring the feeding level of weaned piglets are separated and removed; after the separated impurities such as stones and small iron parts fall into the lower end of the discharge pipe 1, they are discharged through the third air shut-off device 12, and the operator can collect the separated and discharged impurities with containers such as material bags or material barrels.

[0040] By matching and adjusting the feeding speed of the feeder 4 and the suction speed of the fan 9, the suction speed of the fan 9 can be low enough to make the airflow through the material separation device 2 smoother, minimize energy consumption, reduce production costs, and achieve the best impurity removal effect.

[0041] After the above-mentioned impurity removal treatment, the clean weaned piglet feed entering the connecting pipe 3 further enters the material separation device 2. After the material separation action of the material separation device 2, the material falls into the bottom of the material separation device 2 and is accumulated. The material can be separated and discharged through the second air lock 11 at the lower part of the material separation device 2. Low-impurity weaned piglet feed can be obtained from the discharge port of the second air lock 11. The operator can collect the separated and discharged materials, or connect the discharge port of the second air lock 11 with the feed port of the device of the next processing step to further process the materials. The air flow flows out from the upper part of the material separation device 2 and enters the dust collector 7 through the air duct 13. The dust collector 7 recovers the material remaining in the air flow and discharges the recovered material from the first air lock 10. Low-impurity weaned piglet feed can be obtained from the discharge port of the first air lock 10. The operator can collect the discharged material or connect the discharge port of the first air lock 10 with the feed port of the device of the next processing step, thereby improving the recovery rate of the feed during the processing and reducing material loss.
