Description

Technical Field

[0001] This utility model relates to the technical field of feed production screening devices, specifically to a feed production screening device with efficient impurity removal function. Background Technology

[0002] In the feed production process, the purity of raw materials plays a decisive role in feed quality. High-quality feed can not only ensure the healthy growth of livestock and poultry and improve breeding efficiency, but also reduce the risk of livestock and poultry diseases caused by feed impurities. However, the raw materials used in current feed production are widely and complex. During collection, transportation and storage, various impurities are easily mixed in. These impurities include not only small sand, dust and straw, but also foreign objects such as branches and metal blocks that are larger than the feed raw materials.

[0003] Existing screening equipment often only has a single or simple filtration structure, which makes it difficult to remove impurities of different properties and sizes in a comprehensive and efficient manner. Although some devices can perform preliminary filtration of small particulate impurities, they are not effective in treating fine dust. This dust not only affects the appearance and taste of feed, but may also cause respiratory diseases in livestock and poultry during feeding. Utility Model Content

[0004] Therefore, this utility model provides a feed production screening device with efficient impurity removal function, which solves the problem that existing screening equipment is unable to comprehensively and efficiently remove impurities of different properties and sizes through a filtration component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feed production screening device with efficient impurity removal function, comprising an outer shell assembly, a filter assembly inside the outer shell assembly, an anti-clogging component inside the filter assembly, the outer shell assembly including an outer shell, a variable frequency fan fixedly mounted on one side of the outer shell, a feed discharge plate fixedly mounted inside the outer shell, impurity discharge channels on both sides of the outer shell, and baffles fixedly mounted on both sides of the outer shell, the filter assembly including a flexible connecting sleeve, a filter channel unit inside the flexible connecting sleeve, a vibrator mounted on the top of the filter channel unit, the filter channel unit including a feed channel, a first filter channel, a second filter channel, and a third filter channel inside the feed channel, a small impurity filter screen at the bottom of the first filter channel, floating dust filter screens on both sides of the second filter channel, and a large impurity filter screen at the bottom of the third filter channel, the anti-clogging component including a motor, a reciprocating screw at one end of the motor, a sliding seat sleeved on the outside of the reciprocating screw, an anti-clogging brush fixedly mounted on the bottom of the sliding seat, and two rubber sleeves fixedly mounted on the outside of the reciprocating screw.

[0006] Preferably, the flexible connecting sleeve is fixedly connected to the outer shell, and the flexible connecting sleeve is fixedly connected to the feed channel.

[0007] Preferably, the first filter channel, the second filter channel, and the third filter channel are connected to each other.

[0008] Preferably, the motor is located outside the housing and is fixedly connected to one side wall of the housing, and the output end of the motor is fixedly connected to one end of the reciprocating lead screw.

[0009] Preferably, the reciprocating lead screw passes through both side walls of the outer casing and is connected to both side walls of the outer casing via bearings; the reciprocating lead screw passes through both side walls of the flexible connecting sleeve; and the reciprocating lead screw passes through both side walls of the feed channel.

[0010] Preferably, the sliding seat is sleeved outside the reciprocating screw and connected to the reciprocating screw through a ball screw pair, and the top of the sliding seat is slidably connected to the top of the third filter channel.

[0011] Preferably, the bottom of the anti-clogging brush is in contact with the large impurity filter screen.

[0012] Preferably, the rubber sleeve is in contact with the sidewall of the third filter channel.

[0013] The present invention has the following advantages:

[0014] 1. The three-stage filtration structure constructed through the filtration components is designed to address different types of impurities. The small impurity filter in the first filtration channel, in conjunction with a vibrator, efficiently separates small particles such as sand and gravel. The second filtration channel, with the assistance of a variable frequency fan and a dust filter, precisely removes fine dust particles. The large impurity filter in the third filtration channel intercepts large foreign objects such as tree branches, achieving comprehensive removal from fine dust to large impurities. This overcomes the limitations of the single filtration structure in existing equipment, adapts to the impurity removal needs of feed ingredients from complex sources, and provides comprehensive, efficient, and highly adaptable impurity removal.

[0015] 2. The anti-clogging component, driven by a motor-driven reciprocating screw, moves the anti-clogging brush back and forth to clean, effectively preventing large impurities from clogging the filter screen and ensuring continuous and efficient screening. The combination of the rubber sleeve and the sealing structure prevents impurities from entering the transmission parts, reducing equipment failure. At the same time, the flexible connection design of the soft connecting sleeve does not affect the vibration screening effect and reduces the overall shaking of the device. The reasonable structural layout of each component makes subsequent maintenance operations such as cleaning or replacing the filter screen simpler, ensuring stable and reliable operation and convenient maintenance.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1 -Appendix Figure 4 This utility model provides a feed production screening device with high-efficiency impurity removal function, including an outer shell assembly 10, a filter assembly 20 inside the outer shell assembly 10, an anti-clogging component 30 inside the filter assembly 20, an outer shell assembly 10 including an outer shell 11, a variable frequency fan 12 fixedly mounted on one side of the outer shell 11, a feed discharge plate 13 fixedly mounted inside the outer shell 11, impurity discharge channels 14 on both sides of the outer shell 11, and baffles 15 fixedly mounted on both sides of the outer shell 11. The filter assembly 20 includes a flexible connecting sleeve 21, a filter channel unit 22 inside the flexible connecting sleeve 21, and a vibrator 2 on the top of the filter channel unit 22. 3. The filter channel unit 22 includes a feed channel 221. The feed channel 221 is provided with a first filter channel 222, a second filter channel 224, and a third filter channel 226. The bottom of the first filter channel 222 is provided with a small impurity filter screen 223. Both sides of the second filter channel 224 are provided with floating dust filter screens 225. The bottom of the third filter channel 226 is provided with a large impurity filter screen 227. The anti-clogging component 30 includes a motor 31. One end of the motor 31 is provided with a reciprocating lead screw 32. A sliding seat 33 is sleeved on the outside of the reciprocating lead screw 32. An anti-clogging brush 34 is fixedly provided at the bottom of the sliding seat 33. Two rubber sleeves 35 are fixedly sleeved on the outside of the reciprocating lead screw 32.

[0025] In this embodiment, to achieve the goal of efficient and phased removal of impurities of different properties and sizes from feed, the filter channel unit 22 is divided into a first filter channel 222, a second filter channel 224, and a third filter channel 226, forming a phased filtration structure: the small impurity filter screen 223 at the bottom of the first filter channel 222 can specifically filter small particulate impurities, and the high-frequency vibration of the vibrator 23 enhances the impurity separation efficiency, with small impurities being discharged through the impurity discharge channel 14 below; the floating dust filter screens 225 on both sides of the second filter channel 224 cooperate with the variable frequency fan 12 on one side of the outer casing 11, and the airflow generated by the variable frequency fan 12 can remove floating dust from the feed. The side dust filter 225 blows out of the second filter channel 224; the large impurity filter 227 at the bottom of the third filter channel 226 intercepts large impurities, and the feed discharge plate 13 set below it can receive the screened qualified feed to ensure the orderly discharge of feed. At the same time, the two rubber sleeves 35 on the outside of the reciprocating screw 32 in the anti-clogging component 30 can seal the gap between the third filter channel 226 and the reciprocating screw 32. Combined with the existing sealing structure at the connection between the reciprocating screw 32 and the sliding seat 33, it can effectively prevent impurities from entering the transmission part. With the anti-clogging brush 34 cleaning the large impurity filter 227, it further ensures the continuous and stable operation of the device.

[0026] To ensure smooth feed flow between filtration channels, the device employs the following technical solution: A flexible connecting sleeve 21 is externally and fixedly connected to the outer shell 11, while the inner part of the flexible connecting sleeve 21 is fixedly connected to the feed channel 221. The first filtration channel 222, the second filtration channel 224, and the third filtration channel 226 are interconnected. The flexible connecting sleeve 21 has a certain elastic deformation capability. When the vibrator 23 drives the filtration channel unit 22 to vibrate, it can flexibly connect the filtration channel unit 22 to the outer shell 11, preventing the vibration from being directly transmitted to the outer shell 11 and causing the entire device to shake. This ensures the stability of the filtration channel unit during vibration and does not affect the auxiliary effect of vibration on feed screening. The interconnected design of the first filtration channel 222, the second filtration channel 224, and the third filtration channel 226 allows feed that has undergone small particle impurity screening through the first filtration channel 222 to naturally flow into the second filtration channel 224 for dust removal. The treated feed then smoothly enters the third filtration channel 226 for large impurity filtration, forming a continuous screening process and preventing feed from stagnating and accumulating during transport.

[0027] To achieve stable operation of the anti-clogging component 30 and prevent filter clogging, the device employs the following technical solution: Motor 31 is located outside the outer casing 11 and fixedly connected to one side wall of the outer casing 11. The output end of motor 31 is fixedly connected to one end of reciprocating screw 32. The reciprocating screw 32 passes through both side walls of the outer casing 11 and is connected to both side walls of the outer casing 11 via bearings. The reciprocating screw 32 also passes through both side walls of the flexible connecting sleeve 21 and both side walls of the feed channel 221. A sliding seat 33 is sleeved outside the reciprocating screw 32 and connected to the reciprocating screw 32 via a ball screw pair. The top of the sliding seat 33 is slidably connected to the top of the third filter channel 226. The bottom of the anti-clogging brush 34 contacts the large impurity filter screen 227. The rubber sleeve 35 contacts the side wall of the third filter channel 226. The motor 31 is fixed outside the outer casing 11, preventing internal feed clogging. To prevent impurities from contaminating or interfering with the motor, its output directly drives the reciprocating screw 32. A bearing connection ensures the reciprocating screw 32 rotates stably on the housing 11. The design of the reciprocating screw 32, which passes through all components, allows power to be effectively transmitted to the filter channel unit 22. Combined with the ball screw pair connection, the sliding seat 33 smoothly reciprocates as the reciprocating screw 32 rotates. The sliding connection between the sliding seat 33 and the top of the third filter channel 226 further enhances the stability of the movement. The anti-clogging brush 34, in contact with the large impurity filter screen 227, continuously cleans the screen under the action of the sliding seat, promptly removing attached large impurities. The rubber sleeve 35, in contact with the side wall of the third filter channel 226, fills the gaps at the reciprocating screw's penetration point, preventing feed and impurities from leaking out or entering the internal gaps of the device, ensuring the sealing of the filtration process and the coordination of the device's operation.

[0028] The usage process of this utility model is as follows: When using this utility model, first turn on the variable frequency fan 12 and vibrator 23, and input the feed to be screened into the feed channel 221 through the feed inlet. After the feed enters the first filter channel 222, under the high-frequency vibration generated by the vibrator 23, the distance between the feed particles increases and the fluidity is enhanced. Small particles such as sand, gravel, and straw are driven by their own weight and the impact force generated by the vibration, passing through the small impurity filter screen 223 and falling into the impurity discharge channel 14 below, and then being discharged outside the device. Subsequently, the feed enters the second filter channel 224. The airflow generated by the variable frequency fan 12 flows in the channel, raising the tiny floating dust in the feed. The floating dust moves with the airflow and is blown out of the second filter channel 224 through the floating dust filter screen 225 on the other side, merging with the small particles of impurities screened out by the small impurity filter screen 223. The feed particles continue to enter the third filter channel 226. In the third filter channel 226, the large impurity filter screen 227 intercepts larger impurities such as branches and metal blocks. Qualified feed... The large impurities fall onto the feed discharge plate 13 through the large impurity filter screen 227 and are then discharged from the feed discharge plate 13, completing the screening process. The large impurities are discharged through the outlet of the third filter channel 226. Throughout the screening process, the motor 31 works continuously, and its output shaft drives the reciprocating screw 32 to rotate. Since the sliding seat 33 is connected to the reciprocating screw 32 through a ball screw pair, the rotation of the reciprocating screw 32 drives the sliding seat 33 to perform reciprocating linear motion on the reciprocating screw 32. The anti-clogging brush 34 fixed at the bottom of the sliding seat 33 moves synchronously with the sliding seat 33. The large impurity filter screen 227 is continuously cleaned to prevent large particles from clogging the filter screen pores, ensuring the filtration efficiency and unobstructed flow of the large impurity filter screen 227. At the same time, the rubber sleeve 35 fixedly fitted on the outside of the reciprocating screw 32 can seal and protect the gap between the third filter channel 226 and the reciprocating screw 32 during the sliding process, preventing impurities from entering. Meanwhile, the connection between the reciprocating screw 32 and the sliding seat 33 is sealed using existing technology to prevent impurities from entering. The baffle 15 protects the motor 31 to prevent impurities from falling in.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
