Description

Technical Field

[0001] This application relates to the field of feeding devices, and more particularly to a feeding nozzle. Background Technology

[0002] Currently available feeding nozzles are mostly simple straight-cylinder structures (such as...) Figure 1 As shown), or partially rigid, flat, diffused structures (such as...). Figure 2 As shown in the figure, it is not specifically designed for indoor fishpond farming scenarios and powder feed conveying characteristics. In practical applications, the following technical defects exist: powder feed is prone to agglomeration into clumps during the mixing and conveying process with airflow, and airflow is prone to turbulence in the feeding nozzle, resulting in concentrated powder feed drop points after spraying, poor feeding uniformity, causing fish to compete for food, reducing farming efficiency, and also easily causing powder feed accumulation and waste, and polluting the indoor fishpond water quality.

[0003] In most cases, existing technologies require regular manual cleaning of the inner wall of the feeding nozzle to solve this problem. However, regular cleaning is a phased action and cannot remove the powder from the inner wall of the feeding nozzle in real time, thus failing to fundamentally solve problems such as nozzle blockage and uneven feeding. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention application is to provide a feeding nozzle that can prevent material blockage and improve the uniformity of discharge.

[0005] This invention provides a feeding nozzle, comprising: an installation pipe, a feeding component, and a water-blocking component. The installation pipe is connected to a feeding pipe for conveying materials. The feeding component is deformable. The water-blocking component is connected to the connection between the installation pipe and the feeding component, and extends at least partially into the feeding component to form a water-blocking portion surrounding at least a portion of the feeding component. The feeding component includes a feeding section and a connecting section connected to the installation pipe. The connecting section is substantially hollow cylindrical. The feeding section has a hollow structure and includes a first end and a second end distributed axially along the connecting section. The first end is connected to the connecting section or integrally formed, and the second end has a feeding opening that forms a straight line when stationary. The feeding part is defined as follows: a first direction perpendicular to the axial direction of the connecting part and a second direction perpendicular to both the first direction and the axial direction of the connecting part; viewed from the first direction, the feeding part is a first trapezoidal structure, and the shorter side of the first trapezoidal structure is closer to the mounting pipe than the longer side; viewed from the second direction, the feeding part is a second trapezoidal structure, and the longer side of the second trapezoidal structure is closer to the mounting pipe than the shorter side; the feeding opening is located on the longer side of the first trapezoidal structure and on the shorter side of the second trapezoidal structure; when the feeding nozzle is working, airflow flows inside the feeding part, causing the feeding part to deform and allowing the shape of the feeding opening to change between a straight line and an O shape.

[0006] In one possible implementation, the outer diameter of the mounting tube ranges from 20 mm to 30 mm; the length of the short side of the first trapezoidal structure is the same as the outer diameter of the mounting tube, and the length of the long side of the second trapezoidal structure ranges from 48 mm to 72 mm; the length of the long side of the second trapezoidal structure is the same as the outer diameter of the mounting tube, and the length of the short side of the second trapezoidal structure ranges from 1 mm to 3 mm; the heights of the first trapezoidal structure and the second trapezoidal structure are the same, and the heights of both range from 80 mm to 120 mm.

[0007] In one possible implementation, the wall thickness of the feeding component gradually decreases along the direction from the connecting part to the feeding part; the first wall thickness of the end of the connecting part connected to the mounting pipe is in the range of 3mm to 5mm, the second wall thickness of the second end is in the range of 1mm to 3mm, and the second wall thickness is less than the first wall thickness.

[0008] In one possible implementation, the feeding nozzle also includes a baffle located between the water-blocking component and the feeding opening, with the baffle positioned closer to the feeding opening. The baffle is deformable. When the feeding nozzle is in operation, the feeding component deforms, causing the baffle to vibrate and generate an airflow that washes over the material at the feeding opening.

[0009] In one possible implementation, the feeding nozzle further includes multiple vertical reinforcing ribs that extend along the direction from the connecting part to the feeding part. The two ends of the multiple vertical reinforcing ribs extend to the connection between the mounting pipe and the feeding component and the feeding opening, respectively. There is a first preset interval between two adjacent vertical reinforcing ribs. When viewed from the first direction, the multiple vertical reinforcing ribs are located in the first trapezoidal structure.

[0010] In one possible implementation, the feeding nozzle further includes multiple transverse reinforcing ribs, which are arranged around the feeding component circumferentially along the connecting portion and axially along the connecting portion, with a second preset interval between adjacent transverse reinforcing ribs.

[0011] In one possible implementation, the feeding component includes two separation ports extending along the direction from the connecting portion to the feeding portion, the two separation ports communicating with the feeding opening, and the two separation ports being arranged along a second direction; a plurality of transverse reinforcing ribs are detachably connected to the feeding component, and when at least part or all of the plurality of transverse reinforcing ribs are disassembled, the two separation ports can change the vibration characteristics of the feeding opening.

[0012] In one possible implementation, the feeding nozzle also includes a metal wire integrally formed into the mounting tube and / or feeding component, the metal wire having a preset length and being groundable.

[0013] In one possible implementation, the installation pipe, feeding component, and water-blocking component are integrally molded.

[0014] In one possible implementation, the water-blocking part extends along a conical surface, and the inner diameter of the side of the water-blocking part near the feeding opening is larger than the inner diameter of the side of the water-blocking part near the installation pipe.

[0015] The aforementioned feeding nozzle allows materials to smoothly enter the feeding section and be ejected from the feeding opening through the connection between the feeding component and the installation pipe. When gas is flowing, the deformability of the feeding component allows the shape of the feeding opening to change between a straight line and an "O" shape, thereby preventing material from clogging in the feeding nozzle and improving the uniformity of the material output from the feeding nozzle.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0032] To clearly illustrate the technical solution of this application, the following are also defined: Figure 3 The directions shown are front, back, left, right, up, and down.

[0033] like Figure 3As shown, this application embodiment provides a feeding nozzle 100 for feeding and spraying materials. Specifically, the feeding nozzle 100 includes an installation pipe 11, a feeding component 12, and a water-blocking component 13. The installation pipe 11 is connected to a feeding pipe 200 for conveying materials, and the installation pipe 11 is used to fix the feeding nozzle 100 to the feeding pipe 200. The feeding component 12 is deformable and connected to the installation pipe 11, and the feeding component 12 is used to feed materials. The water-blocking component 13 is connected to the connection between the installation pipe 11 and the feeding component 12, and the water-blocking component 13 extends at least partially toward the feeding component 12, thereby enabling the water-blocking component 133 to form a water-blocking portion 131 surrounding at least a portion of the feeding component 12. In this application, the water-blocking component 13 can block condensate generated on the surface of the feeding nozzle in a closed aquaculture environment through the water-blocking portion 131.

[0034] In some embodiments, the material may be powdered feed or fertilizer.

[0035] like Figure 3 and Figure 4 As shown, in one implementation, the feeding component 12 includes a feeding section 121 and a connecting section 122 connected to the mounting pipe 11. The feeding section 121 can change its shape according to the airflow size so that the material can be more evenly distributed inside the feeding section 121, thereby making the material more evenly mixed in the airflow and sprayed out, which facilitates the spraying and delivery of the material, thereby avoiding material contamination and accumulation inside the feeding component 12. At the same time, the connecting section 122 can prevent the material from being blocked and accumulating when it enters the feeding section 121 from the mounting pipe 11, improving the smoothness of material conveying of the feeding nozzle 100, thereby facilitating the meeting of the material spraying and distribution requirements and improving the uniformity of material spraying of the feeding nozzle 100.

[0036] Specifically, the connecting part 122 is basically a hollow cylinder, and the feeding part 121 is a hollow structure and includes a first end 1211 and a second end 1212 distributed along the axial direction of the connecting part 122. The first end 1211 is connected to the connecting part 122 or integrally formed, and the second end 1212 has a feeding opening 123, which is in the shape of an "I" when stationary.

[0037] In some embodiments, the material of the feeding component 12 can be silicone, rubber, or other deformable materials. The feeding component 12 can deform according to the size of the airflow and has a certain rebound and reset characteristics. With the above configuration, the "I"-shaped shape of the feeding opening 123 can compress and guide the material and gas moving in a straight direction into a fan-shaped spray, thereby better distributing the fed material evenly. In addition, since the material sprayed from the "I"-shaped feeding opening 123 is in a flat fan shape, it can accurately spray the material when spraying narrow gaps or channels, avoiding waste caused by spraying material on the outside of gaps or channels, thereby improving the uniformity and accuracy of material spraying by the feeding nozzle 100.

[0038] like Figure 5 and Figure 6 As shown, a first direction perpendicular to the axial direction of the connecting portion 122 and a second direction perpendicular to both the first direction and the axial direction of the connecting portion 122 are further defined.

[0039] like Figure 5 As shown, when viewed from the first direction, the feeding section 121 is a first trapezoidal structure 101, and the shorter side L1 of the first trapezoidal structure 101 is closer to the mounting pipe 11 than the longer side L2.

[0040] like Figure 6 As shown, when viewed from the second direction, the feeding section 121 is a second trapezoidal structure 102, and the long side L4 of the second trapezoidal structure 102 is closer to the mounting pipe 11 than the short side L3.

[0041] like Figure 5 and Figure 6 As shown, the feeding opening 123 is located on the long side L2 of the first trapezoidal structure 101 and on the short side L3 of the second trapezoidal structure 102. With this configuration, when the feeding nozzle 100 is working, airflow flows through the feeding component 12, and the material is mixed in the airflow and conveyed together. By adjusting the ratio of the material supply to the airflow magnitude (air-to-material ratio), the feeding density at the feeding opening 123 can be controlled, i.e., the amount of material sprayed by the feeding nozzle 100 per unit time. Because the feeding component 12 can deform accordingly during operation, the shape of the feeding opening 123 can be in a straight line (refer to...). Figure 3 ) to "O" shape (refer to) Figure 4 The shape between the two is continuously transformed.

[0042] Specifically, during normal operation, a stable airflow flows within the feeding component 12. Under the action of the airflow, the feeding opening 123 opens from a stationary "I" shape to an "O" shape in the working state. Since the feeding component 12 has deformation recovery capability, the feeding opening 123 has a certain contraction force after opening. After the feeding opening 123 slightly contracts, the interaction force between it and the stable airflow increases, causing the feeding opening 123 to open again. Thus, the feeding opening 123 can continuously and cyclically alternate rapidly from an "I" shape to an "O" shape. Furthermore, the rapid alternation of the feeding opening 123 from an "I" shape to an "O" shape has a certain amplitude and frequency, making it difficult for materials to accumulate at the feeding opening 123 and improving the anti-clogging capability of the feeding nozzle 100. Furthermore, through the above-mentioned configuration, when the feeding opening 123 undergoes corresponding deformation, the inner wall surface of the feeding section 121 will also undergo slight deformation. Under the combined action of the airflow and the deformation of the inner wall surface of the feeding section 121, the material inside the feeding nozzle 100 can be prevented from sticking and accumulating, thereby improving the uniformity of material spraying from the feeding nozzle 100, better controlling the distribution range of material spraying, and thus better meeting the distribution requirements of the feeding operation.

[0043] In this application, the first direction refers to Figure 3 The vertical direction in the middle, the second direction refers to Figure 3 The left and right directions in the middle.

[0044] like Figure 7 and Figure 8 As shown, in this embodiment, the length of the short side L1 of the first trapezoidal structure 101 is the same as the outer diameter D of the mounting pipe 11, and the length L4 of the long side of the second trapezoidal structure 102 is the same as the outer diameter D of the mounting pipe 11. With this configuration, even if the feeding device 12 deforms during normal operation, the material can still enter the feeding device 12 normally, avoiding blockage.

[0045] In one implementation, the outer diameter D of the mounting tube 11 ranges from 20 mm to 30 mm. The length L2 of the long side of the first trapezoidal structure 101 ranges from 48 mm to 72 mm. The length L3 of the short side of the second trapezoidal structure 102 ranges from 1 mm to 3 mm.

[0046] Specifically, the outer diameter D of the mounting tube 11 ranges from 22mm to 28mm. The length L2 of the long side of the first trapezoidal structure 101 ranges from 54mm to 66mm. The length L3 of the short side of the second trapezoidal structure 102 ranges from 1.5mm to 2.5mm.

[0047] More specifically, the outer diameter D of the mounting pipe 11 ranges from 25mm. The length L2 of the long side of the first trapezoidal structure 101 ranges from 60mm. The length L3 of the short side of the second trapezoidal structure 102 ranges from 2mm. The height H of the first trapezoidal structure 101 and the second trapezoidal structure 102 is the same, and the height H of both ranges from 80mm to 120mm. Specifically, the height H of both ranges from 90mm to 110mm. More specifically, the height H of both ranges from 99mm. By setting the above three sets of parameters, the uniformity of material distribution can be ensured even when the airflow magnitude changes. Furthermore, through the above configuration, the outer diameter D of the mounting pipe 11 is consistent with the short side L1 of the first trapezoidal structure 101 and the long side L4 of the second trapezoidal structure 102. This ensures that the material can smoothly enter the feeding device 12 from the mounting pipe 11 even when the feeding device 12 is deformed. It also avoids the material accumulating on the pipe wall of the mounting pipe 11 due to the reduced airflow velocity caused by the outer diameter D being too large. In addition, it avoids the material getting stuck inside the mounting pipe 11 due to the narrow space caused by the outer diameter D being too small, thereby preventing material blockage and improving the efficiency of material feeding.

[0048] By setting the above, it is possible to avoid the excessive amplitude of the feeding opening 123 due to an excessively large length L3, which would increase the scale weight, and to avoid the excessively small amplitude of the feeding opening 123 due to an excessively small length L3, which would also increase the scale weight, thereby improving the anti-clogging ability of the feeding component 12.

[0049] Furthermore, the above settings prevent the material spraying from becoming too dispersed due to an excessively large length L2, and also prevent the material spraying from becoming too concentrated and the dispersion effect from becoming too insignificant due to an excessively small length L2, thus achieving the optimal material spraying dispersion effect. Additionally, the excessive height H prevents the feeding component 12 from becoming too heavy, causing it to collapse at the feeding opening 123 and resulting in uneven spraying. Conversely, the excessively small height H prevents the mixing stroke of the material and gas in the feeding component 12 from becoming too short, leading to insufficient mixing, thereby improving the uniformity of material spraying.

[0050] like Figure 7 As shown, in this embodiment, the wall thickness of the feeding member 12 gradually decreases along the direction from the connecting part 122 to the feeding part 121. The rigidity of the wall thickness of the feeding member 12 decreases as the wall thickness decreases, and the part with a smaller wall thickness has better deformation capacity, thereby ensuring that the feeding member 12 can maintain good deformation performance.

[0051] In one implementation, the first wall thickness T1 of the end of the connecting part 122 connected to the mounting tube 11 ranges from 3mm to 5mm, the second wall thickness T2 of the second end 1212 ranges from 1mm to 3mm, and the second wall thickness T2 is less than the first wall thickness T1.

[0052] Specifically, the first wall thickness T1 of the end of the connecting part 122 connected to the mounting tube 11 ranges from 3.5mm to 4.5mm, and the second wall thickness T2 of the second end 1212 ranges from 1.5mm to 2.5mm.

[0053] More specifically, the first wall thickness T1 of the end of the connecting part 122 connected to the mounting tube 11 is in the range of 4 mm, and the second wall thickness T2 of the second end 1212 is in the range of 2 mm.

[0054] Through the above settings, the feeding component 12 can be guaranteed to have both deformability and deformation recovery capability. The first wall thickness T1 of the feeding component 12 utilizes a relatively high thickness to provide a certain structural rigidity to maintain the overall shape of the feeding component 12, and drives the second wall thickness T2 of the feeding component 12 to recover deformation when no airflow passes through the feeding component 12. In addition, through the above settings, it is possible to avoid the first wall thickness T1 being too large, which would lead to excessive structural rigidity of the feeding component 12 and reduce its deformation capability, and it is also possible to avoid the first wall thickness T1 being too small, which would lead to insufficient structural rigidity and inability to recover deformation. Furthermore, it is possible to avoid the second wall thickness T2 being too large, which would lead to insensitive opening of the feeding opening 123, and it is also possible to avoid the second wall thickness T2 being too small, which would lead to untimely closing of the feeding opening 123, thereby ensuring that the deformation capability of the feeding component 12 is within the optimal range.

[0055] like Figure 9 As shown, in this embodiment, the feeding nozzle 100 also includes a material baffle 14. The material baffle 14 vibrates when the feeding member 12 deforms, generating an airflow that washes away the material at the feeding opening 123, thereby preventing material from adhering to the feeding opening 123. Specifically, the material baffle 14 is located between the water-blocking member 13 and the feeding opening 123, and is positioned closer to the feeding opening 123. The material baffle 14 is deformable. Through this arrangement, the vibration generated by the material baffle 14 can be better transmitted to the feeding opening 123. Simultaneously, the airflow generated by the vibration of the material baffle 14 blows away the material near the feeding opening 123, thus helping to prevent material from adsorbing and accumulating on the outside of the feeding opening 123, preventing material from becoming moldy and falling off, thereby affecting the feeding effect.

[0056] like Figure 10As shown, the feeding nozzle 100 also includes multiple vertical reinforcing ribs 15. The vertical reinforcing ribs 15 are used to adjust the amplitude and frequency of the feeding component 12 at different wind speeds, thereby improving the anti-clogging capability of the feeding nozzle 100 when the wind speed at the feeding opening 123 is inconsistent. In one embodiment, the multiple vertical reinforcing ribs 15 extend along the direction from the connecting portion 122 to the feeding portion 121, with both ends of the multiple vertical reinforcing ribs 15 extending to the connection between the mounting pipe 11 and the feeding component 12, and to the feeding opening 123, respectively. There is a first preset interval Y1 between two adjacent vertical reinforcing ribs 15. Viewed from the first direction, the structure of the multiple vertical reinforcing ribs 15 is located within the first trapezoidal structure 101. Through the above arrangement, by adjusting the first preset interval Y1 of the vertical reinforcing ribs 15 at different wind speeds, the amplitude and frequency of the feeding component 12 can be adjusted to achieve the best anti-clogging effect. Furthermore, when the material characteristics are different, such as different particle sizes or different moisture contents, the deformation characteristics of the feeding component 12 can be changed by adjusting the number of vertical reinforcing ribs 15 and the first preset interval Y1. This allows the feeding component 12 to adapt to different air-to-material ratios (the ratio of air flow rate to material quantity), preventing the feeding nozzle 100 from becoming clogged due to different material characteristics, thereby improving the feeding efficiency of the feeding nozzle 100.

[0057] like Figure 11 As shown, the feeding nozzle 100 also includes multiple transverse reinforcing ribs 16. The transverse reinforcing ribs 16 are used to adjust the amplitude and frequency of the feeding component 12 at different wind speeds, thereby improving the anti-clogging capability of the feeding nozzle 100 when the wind speed at the feeding opening 123 is inconsistent. In one embodiment, multiple transverse reinforcing ribs 16 are arranged circumferentially around the feeding component 12 along the connecting portion 122, and are arranged axially along the connecting portion 122, with a second preset interval Y2 between adjacent transverse reinforcing ribs 16. Through this arrangement, adjusting the second preset interval Y2 of the transverse reinforcing ribs 16 at different wind speeds allows the amplitude and frequency of the feeding opening 123 to be adjusted to achieve the optimal anti-clogging effect. Furthermore, when the material characteristics are different, such as different particle sizes or different moisture contents, the deformation characteristics of the feeding component 12 can be changed by adjusting the number of transverse reinforcing ribs 16 and the second preset interval Y2, so that the feeding component 12 can adapt to different air-to-material ratios (the ratio of air flow rate to material quantity), avoid the feeding nozzle 100 from being blocked due to different material characteristics, and thus improve the feeding efficiency of the feeding nozzle 100.

[0058] like Figure 11As shown, the feeding component 12 includes two separation ports 124 extending along the direction from the connecting portion 122 to the feeding portion 121. The anti-clogging effect of the feeding nozzle 100 is adjusted by regulating the opening degree of the separation ports 124. In one embodiment, the two separation ports 124 are connected to the feeding opening 123, and the two separation ports 124 are arranged along a second direction. A plurality of transverse reinforcing ribs 16 are detachably connected to the feeding component 12. When at least part or all of the plurality of transverse reinforcing ribs 16 are disassembled, the two separation ports 124 can change the vibration characteristics of the feeding opening 123. With the above arrangement, by disassembling different numbers of transverse reinforcing ribs 16, the opening degree of the separation ports 124 can be changed, thereby regulating the vibration characteristics of the feeding opening 123. In addition, under the action of airflow, the upper and lower parts of the feeding component 12 vibrate. Due to the presence of the separation ports 124, the upper and lower parts of the feeding component 12 slap each other during vibration, further improving the anti-adsorption properties of the material on the inner wall of the feeding component 12, thereby improving the anti-clogging ability of the feeding nozzle 100.

[0059] In this embodiment, when the outer diameter D is set to 22mm, the height H to 99mm, the length L3 of the short side of the second trapezoidal structure to 1mm, the first wall thickness T1 to 3mm, and the second wall thickness T2 to 1mm, the feeding opening 123 will produce different degrees of opening and closing vibrations when material-carrying gas with different flow rates is introduced into the feeding nozzle 100 (with a constant gas-to-material ratio). As the wind speed gradually increases, the amplitude of the feeding opening 123 first increases rapidly and then the increase slows down. After the amplitude of the feeding opening 123 reaches 20mm, it begins to slowly decrease; the vibration frequency of the feeding opening 123 continuously increases with the increase of wind speed. By comparing the weight of the feeding nozzle 100 before and after the test, the scale weight under different wind speeds for the same operating time can be calculated. Based on the data, it can be concluded that the feeding nozzle 100 has a good anti-scaling effect when the wind speed is greater than or equal to 4m / s and less than or equal to 6m / s.

[0060] Understandably, when the wind speed is too high or too low, or the powder fineness is different, adjustments can be made through installation and other means. Figure 9 , Figure 10 The nozzle shown can ultimately achieve a good anti-scaling effect. Specific experimental data are shown in the anti-scaling effect parameter table for the feeding nozzle.

[0062] like Figure 12 As shown, the feeding nozzle 100 also includes a metal wire 17, which can remove static electricity from the feeding nozzle 100, thereby preventing the electrostatic adsorption of materials. In one embodiment, the metal wire 17 is integrally formed on the mounting tube 11 and / or the feeding component 12, and the metal wire 17 has a preset length and can be grounded.

[0063] In some embodiments, the portion of the metal wire 17 near the feeding nozzle 100 is located inside the feeding pipe 200. The portion of the metal wire 17 away from the feeding nozzle 100 can pass through the wall of the feeding pipe 200 and is located on the outside of the feeding pipe 200 and grounded. The metal wire 17 is sealed to the wall of the feeding pipe 200 to prevent airflow and material leakage to the outside of the feeding pipe 200. Through this arrangement, the metal wire 17 can remove static electricity generated by the feeding nozzle 100 during the feeding process, thereby preventing the feeding nozzle 100 from adsorbing material and improving the anti-clogging effect of the feeding nozzle 100.

[0064] like Figure 3 As shown, in one embodiment, the mounting pipe 11, the feeding component 12, and the water-blocking component 13 are integrally formed, which facilitates smoother material conveying inside the feeding nozzle 100. With this configuration, there are no connecting gaps inside the feeding nozzle 100, preventing material accumulation at these gaps and thus improving the anti-clogging effect of the feeding nozzle 100. Furthermore, it prevents mold and other microorganisms from surviving at the connecting gaps inside the feeding nozzle 100, thereby avoiding contamination of the fed material and improving material safety.

[0065] like Figure 3 and Figure 7 As shown, in one embodiment, the water-blocking part 131 extends along a conical surface, and the inner diameter of the side of the water-blocking part 131 near the feeding opening 123 is larger than the inner diameter of the side of the water-blocking part 131 near the mounting pipe 11. With this arrangement, water flow cannot flow from the side of the water-blocking part 131 near the feeding opening 123 to the side of the water-blocking part 131 near the mounting pipe 11, thereby preventing water from flowing to the feeding opening 123, preventing material from accumulating and adhering to the damp feeding opening 123, preventing material from clumping, moldy, and falling off, and thus improving the uniformity and safety of material feeding by the feeding nozzle 100.

[0066] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
