Description

Technical Field

[0001] This utility model belongs to the technical field of liquid feed conveying equipment, specifically, it relates to a non-powered liquid feed anti-sinking pipe. Background Technology

[0002] Liquid feed is mainly used in aquaculture, pig farming, and other livestock farming. Compared to traditional dry feed, liquid feed has higher palatability and digestibility, better meeting the nutritional needs of pigs, reducing feed waste, and improving the economic efficiency of farms. On the one hand, liquid feed can bring direct benefits to farms; on the other hand, it can reduce labor costs. Traditional farming involves manually transporting feed to the feeding area, and the larger the farm, the higher the labor costs.

[0003] To address the aforementioned issues, modern aquaculture utilizes facilities such as mixing tanks, pump units, and sterile pipelines. The feed, prepared in proportion, is mixed in the mixing tank and then pumped by the pump unit to the sterile pipeline leading to the feeding area. It is automatically delivered at fixed times and locations, significantly reducing labor costs compared to traditional manual feeding methods.

[0004] However, pipeline transportation of liquid feed has the following problems:

[0005] Liquid feed consists of basic raw materials, protein sources, vitamins, minerals, etc., mixed together to form a liquid with fluidity. Its consistency varies depending on the water ratio, ranging from thin to thick. During flow in a horizontal pipe, high-density substances tend to settle at the bottom, while low-density substances flow away, leaving some high-density substances behind.

[0006] The aforementioned problem of high-density material settling mainly occurs in horizontal pipes. Current methods address this by adding a booster pump to the water pipes to increase pressure and flow rate, flushing away the settled high-density material. While this method solves the settling problem, it also increases equipment and electricity costs. The booster pump itself is not inexpensive, and it needs to be activated every time liquid feed is transported, further increasing electricity costs. Therefore, although this method solves the problem, it significantly increases costs for farms, resulting in low cost-effectiveness. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a non-powered liquid feed anti-sinking pipe, comprising a cylinder open at both ends and a helical blade installed inside the cylinder; at least one helical blade is provided, the helical blade extends along the axial direction of the cylinder and the axial length of the helical blade is not less than 2 / 3 of the cylinder length; the two ends of the central axis of the helical blade are respectively connected to the inner wall of the cylinder through brackets, thereby allowing the helical blade to rotate and connect to the inside of the cylinder; the cross-section of the helical blade is concave, and the blade surface of the helical blade is distributed with axial through holes.

[0008] The preferred embodiment of the non-powered liquid feed anti-settlement pipe provided by this utility model is as follows: There are two spiral blades, which are installed parallel to each other inside the cylinder, and the two spiral blades rotate in opposite directions. Furthermore, the grooved surfaces of the two spiral blades face the liquid inlet end of the cylinder. The liquid feed flowing through the cylinder will drive the two spiral blades to rotate, but the two spiral blades rotate in opposite directions. This is to avoid the situation where the rotation directions are the same, which would easily create a slow-flow zone downstream, causing high-density substances to settle. The reverse rotation can create turbulence, which is equivalent to secondary stirring inside the cylinder, improving the anti-settling effect.

[0009] The preferred embodiment of the non-powered liquid feed anti-sinking pipe provided by this utility model is as follows: the front edge of the inner sidewall and the front edge of the outer sidewall of each spiral blade are provided with rounded corners or chamfers, and both ends of each central shaft are provided with chamfers. All chamfers or rounded corners face the liquid inlet end, that is, opposite to the flow direction of the liquid feed. The rounded corners and chamfers are used to reduce flow resistance.

[0010] The preferred embodiment of the non-powered liquid feed anti-sinking pipe provided by this utility model is as follows: both ends of each central shaft are connected to a corresponding bracket via sealed bearings. The sealed bearings can be used underwater, preventing water and small particles in the liquid feed from entering the sealed bearings and thus not affecting their lifespan. Furthermore, the sealed bearings reduce the rotational resistance of the helical blades, allowing them to rotate even at low flow rates.

[0011] The preferred embodiment of the non-powered liquid feed anti-sinking pipe provided by this utility model is as follows: the support includes multiple connecting rods, and the two ends of each connecting rod are fixedly connected to the outer ring of the corresponding sealing bearing and the inner wall of the cylinder, respectively; the cross-sectional shape of each connecting rod is triangular, and the top edge of the connecting rod faces the liquid inlet end of the cylinder. Each support has three connecting rods, which are located on both sides and above or below the sealing bearing, and the shape of the connecting rods is also designed to reduce flow resistance.

[0012] The preferred embodiment of the non-powered liquid feed anti-sinking pipe provided by this utility model is as follows: both ends of the cylinder are respectively provided with stepped surfaces for connection. The stepped surfaces at both ends of the cylinder can be adapted to the liquid feed conveying pipeline, and the conveying pipeline is provided with steps corresponding to the stepped surfaces. The two are then sealed by a sealing ring, making the connection seamless and easy to assemble and disassemble. It can be used in most existing conveying pipelines.

[0013] The beneficial effects of the non-powered liquid feed anti-sinking pipe of this utility model are as follows:

[0014] 1. The two ends of the cylinder are connected to the liquid feed conveying pipeline. It is mainly used in horizontal pipe sections where sedimentation is prone to occur. When the liquid feed flows through the cylinder, it will drive the spiral blades to rotate. At the same time, the spiral blades will lift up the sedimented high-density material, and achieve a stirring effect while conveying. This can greatly reduce the problem of high-density material sedimentation and accumulation in horizontal pipe sections.

[0015] 2. Compared with existing dust suppression methods using booster pumps, the spiral blades themselves do not require additional power, meaning they do not consume electricity and therefore do not increase the farm's electricity costs.

[0016] 3. The cylindrical and spiral blade structure is simple and the manufacturing cost is much lower than that of a booster pump. The cost of adding an anti-settlement pipe every 5 meters or 8 meters in the conveying pipeline is relatively low, and the same anti-settlement effect can be achieved.

[0017] This utility model also provides another type of non-powered liquid feed anti-sinking pipe, including a cylinder open at both ends and guide vanes installed inside the cylinder, wherein limiting steps are respectively provided inside both ends of the cylinder. At least one guide vane is provided, and one long side of the guide vane is axially fixedly connected to the inner surface of the cylinder, and the guide vane can rotate clockwise or counterclockwise. Specifically, two guide vanes are provided, and the two guide vanes are symmetrically distributed inside the cylinder.

[0018] The beneficial effects of the non-powered liquid feed anti-sinking pipe of this utility model are as follows:

[0019] The liquid feed flows through the inside of the cylinder and is guided by two guide vanes, causing the liquid feed to rotate while flowing. Finally, it flows in a spiral flow in the conveying pipe, effectively solving the problem of sedimentation of high-density substances in liquid feed. Attached Figure Description

[0029] In view of the shortcomings of the prior art, the inventor of this utility model has, through long-term research and extensive practice, proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process, and its principles in conjunction with the accompanying drawings and specific implementation examples.

[0030] Example 1:

[0031] like Figure 1 As shown, Embodiment 1 provides a non-powered liquid feed anti-sinking pipe, including a cylinder 1 open at both ends, with stepped surfaces 10 at each end for connection. The stepped surfaces 10 at both ends of the cylinder 1 can be adapted to liquid feed conveying pipelines, which have steps corresponding to the stepped surfaces 10. The two are then sealed by a sealing ring, ensuring a sealed connection. This allows for easy assembly and disassembly and can be used with most existing conveying pipelines.

[0032] This embodiment also includes helical blades 2 installed inside the cylinder 1. There may be two helical blades 2, or one, three, etc., depending on the size of the cylinder 1; this embodiment does not impose any restrictions. The two helical blades 2 extend along the axial direction of the cylinder 1, and the axial length of each helical blade 2 is not less than 2 / 3 of the length of the cylinder 1. The length of the helical blades 2 has a significant impact on the stirring effect, but the length of the helical blades 2 cannot exceed the length of the cylinder 1.

[0033] The specific connection structure between the helical blade 2 and the cylinder 1 is as follows:

[0034] The two ends of the central shaft 8 of the spiral blade 2 are connected to the inner wall of the cylinder 1 via brackets, thereby allowing the spiral blade 2 to rotate within the cylinder 1. Specifically, the two ends of each central shaft 8 are connected to the corresponding bracket via sealed bearings 3. The sealed bearings 3 can be used underwater, preventing water and small particles in the liquid feed from entering the sealed bearings 3 and thus not affecting their lifespan. The sealed bearings 3 also reduce the rotational resistance of the spiral blade 2, allowing it to rotate even at low flow rates. Furthermore, the bracket includes three connecting rods 4, but is not limited to three. The two ends of each connecting rod 4 are fixedly connected to the outer ring of the corresponding sealed bearing 3 and the inner wall of the cylinder 1, respectively. The cross-sectional shape of each connecting rod 4 is triangular, and the top edge of each connecting rod 4 faces the liquid inlet end of the cylinder 1. The three connecting rods 4 of each bracket are located on either side and above or below the sealed bearing 3, and the shape of the connecting rods 4 is also designed to reduce flow resistance.

[0035] Although the two helical blades 2 are installed parallel inside the cylinder 1, they rotate in opposite directions. The liquid feed flowing through the cylinder 1 drives the two helical blades 2 to rotate. If the two helical blades 2 rotate in the same direction, a slow-flow zone is easily formed downstream, causing high-density materials to settle. Reverse rotation creates turbulence, effectively performing secondary stirring within the cylinder 1 and improving the anti-settling effect.

[0036] To allow rotation at low flow rates, the spiral blade 2 in this embodiment has a concave cross-section, with the concave side facing the liquid inlet end of the cylinder 1. The rotating spiral blade 2 creates a scooping motion, and the concave spiral blade 2 structure can easily move the settling high-density material, resulting in better anti-settling effect. In addition, each spiral blade 2 has axial through holes 5 distributed on its blade surface 9. The purpose of the through holes 5 is to prevent feed particles from adhering to the blade surface 9 and forming residue.

[0037] The structure of the spiral blade 2 is further refined: Rounded corners or chamfers are provided on the front of the inner wall 6 and the front of the outer wall 7 of each spiral blade 2. Here, the inner wall 6 and outer wall 7 refer to the sidewalls of the U-shaped spiral blade 2 closest to the central axis 8 and the sidewalls furthest from the central axis 8, with the blade surface 9 located between these two sidewalls. Chamfers are provided at both ends of each central axis 8, and all chamfers or rounded corners face towards the liquid inlet end, i.e., opposite to the flow direction of the liquid feed. The rounded corners and chamfers are designed to reduce flow resistance and minimize the impact of the anti-sinking pipe on the transport of liquid feed.

[0038] Example 2:

[0039] like Figures 5 to 7As shown, Embodiment 2 provides another type of non-powered liquid feed anti-sinking pipe, including a cylinder 1 open at both ends and guide vanes 11 installed inside the cylinder 1. Limiting steps 12 are provided inside both ends of the cylinder 1. Two conveying pipes are inserted into both ends of the cylinder 1 until they contact the limiting steps 12. There are two guide vanes 11, but not limited to two; there can be three, four, etc., and this embodiment does not impose any limitation. One long side of the guide vane 11 is axially fixed to the inner surface of the cylinder 1, and the guide vane 11 can rotate clockwise or counterclockwise. Specifically, there are two guide vanes 11, symmetrically distributed inside the cylinder 1.

[0040] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
