Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of overflow devices, and in particular to an overflow trough. Background Technology
[0002] In the food and pharmaceutical production process, sometimes it is necessary to drop spherical or lumpy materials into an overflow tank for collection, and then use the overflow tank for cleaning, flavoring or other processes before transferring them to the next process.
[0003] In conventional overflow tank designs, liquids or water often enter directly from the top or bottom. This feeding method results in highly irregular flow of liquid materials, carrying spherical or lumpy materials to the bottom of the overflow tank or to the dead zone, where they remain for extended periods. This prolonged retention can affect hygiene and product quality. Utility Model Content
[0004] The purpose of this invention is to provide an overflow trough to prevent materials from remaining in the overflow trough, thereby improving production efficiency and product quality.
[0005] To solve the above-mentioned technical problems, this utility model provides an overflow groove.
[0006] The overflow tank of this utility model includes a tank body and an inlet flow channel and an outlet flow channel fixedly connected to the tank body.
[0007] The tank is divided into a flow stabilization zone and a feeding zone in sequence along the direction away from the liquid inlet channel, and the feeding zone is used to put in materials;
[0008] The flow stabilization zone includes an inlet tank section and at least one set of rectifier tank sections. The inlet channel is connected to the bottom of the inlet tank section for introducing liquid into the inlet tank section. The inlet tank section has a first upper outlet located at the top and connected to the adjacent set of rectifier tank sections. The set of rectifier tank sections includes an adjacent first tank section and a second tank section. The bottom of the first tank section has a lower outlet to connect to the second tank section. The second tank section has a second upper outlet located at the top for liquid to flow out.
[0009] The second upper liquid outlet of the rectifier tank section group adjacent to the feeding area serves as an overflow outlet. The overflow outlet supplies liquid to flow from the second tank section to the feeding area. The lowest point of the overflow outlet is lower than the lowest point of the inlet of the liquid outlet channel.
[0010] The liquid outlet channel is used to draw liquid containing materials out of the tank in a laminar flow manner.
[0011] Furthermore, the bottom of the tank is provided with a partition extending from bottom to top, which divides the tank into a flow stabilization zone and a feeding zone. The gap between the upper end of the partition and the top of the tank forms the overflow port. The upper end of the partition is lower than the lowest point of the inlet of the liquid outlet channel to reduce turbulence.
[0012] Furthermore, the depth of the lower outlet is greater than or equal to the width of the first tank section.
[0013] Furthermore, the width of the second groove segment is greater than or equal to the width of the first groove segment.
[0014] Furthermore, the widths of both the first and second tank sections are greater than or equal to the width of the liquid inlet tank section.
[0015] Furthermore, the depth of the lower liquid outlet is greater than or equal to the depth of the first upper liquid outlet.
[0016] Furthermore, the cross-sectional area of the liquid inlet channel gradually increases towards the direction of the tank.
[0017] Furthermore, the liquid inlet channel has a tapered section.
[0018] Furthermore, the liquid outlet channel is an inclined channel.
[0019] Furthermore, the cross-sectional area of the inclined flow channel gradually decreases in the direction away from the tank.
[0020] Compared with the prior art, the present invention has at least the following beneficial effects:
[0021] This application divides the tank into a flow stabilization zone and a feeding zone. The flow stabilization zone includes an inlet section and a set of rectifying sections. Liquid enters the inlet section through the inlet channel and then enters the rectifying section group through the first upper outlet. The first and second sections of the rectifying section group achieve orderly liquid flow through the lower and second upper outlets. Finally, the liquid is introduced into the feeding zone through the overflow outlet. This structural design allows the liquid to flow smoothly between the sections, reducing turbulence and solving the problem of irregular liquid and material flow in the overflow tank, which causes material to stagnate at the bottom of the tank or in dead zones, affecting hygiene and product quality. This application can more effectively control the flow of liquid, ensuring that the material flows smoothly out of the tank, thereby improving production efficiency and product quality.

[0034] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0035] The following is in conjunction with the instruction manual appendix. Figure 1 To be continued Figure 4 The overflow groove of this utility model will be introduced.
[0036] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application proposes an overflow tank, including a tank body 1 and an inlet flow channel 20 and an outlet flow channel 30 fixedly connected to the tank body 1.
[0037] The tank 1 is divided into a flow stabilization zone and a feeding zone 16 in sequence along the direction away from the liquid inlet channel 20. The feeding zone 16 is used to put in materials.
[0038] The flow stabilization zone includes an inlet tank section 10 and at least one set of rectifier tank sections. The inlet channel 20 is connected to the bottom of the inlet tank section 10 and is used to introduce liquid into the inlet tank section 10. The inlet tank section 10 has a first upper outlet 11 located at the top and connected to the adjacent rectifier tank section group. The rectifier tank section group includes an adjacent first tank section 12 and a second tank section 13. The bottom of the first tank section 12 has a lower outlet 14 to connect to the second tank section 13. The second tank section 13 has a second upper outlet 15 located at the top for liquid to flow out.
[0039] The second upper liquid outlet 15 of the rectifier tank section group adjacent to the feeding area 16 serves as an overflow outlet. Liquid is supplied from the second tank section 13 to the feeding area 16 through the overflow outlet. The lowest point of the overflow outlet is lower than the lowest point of the inlet of the liquid outlet channel 30.
[0040] The liquid outlet channel 30 is used to draw liquid containing material out of the tank 1 in a laminar flow manner.
[0041] This application divides the tank 1 into a flow stabilization zone and a feeding zone 16. The flow stabilization zone includes a liquid inlet section 10 and a rectifier section group, such as... Figure 2 As shown by the arrows, liquid enters the inlet tank section 10 from the inlet channel 20, and then enters the rectifier tank section group through the first upper outlet 11. The first tank section 12 and the second tank section 13 in the rectifier tank section group achieve orderly liquid flow through the lower outlet 14 and the second upper outlet 15. Finally, the liquid is introduced into the feeding area 16 through the overflow port. This structural design allows the liquid to flow smoothly between the tank sections, reducing turbulence and solving the problem of irregular liquid and material flow in the overflow tank, which causes material to stagnate at the bottom of the tank or in dead zones, affecting hygiene and product quality. This application can more effectively control the flow of liquid, ensuring that the material flows smoothly out of the tank 1, thereby improving production efficiency and product quality.
[0042] Furthermore, in some embodiments, the bottom of the tank 1 is provided with a partition 19 extending from bottom to top, the partition 19 dividing the tank 1 into a flow stabilization zone and a feeding zone 16, the gap between the upper end of the partition 19 and the top of the tank 1 forms the overflow port, and the upper end of the partition 19 is lower than the lowest point of the inlet of the liquid outlet channel 30 to reduce turbulence.
[0043] Specifically, the partition 19 can be configured in several ways. For example, the partition 19 can extend vertically, and its height and width can be adjusted according to the dimensions of the tank 1 and the requirements of liquid flow. The material of the partition 19 can be selected to be corrosion-resistant and wear-resistant to ensure its long-term stability. In addition, the size of the gap between the upper end of the partition 19 and the top of the tank 1 can be optimized according to the liquid flow rate and velocity to further reduce turbulence.
[0044] By setting a partition 19 extending upwards from the bottom of the tank 1, the tank 1 is divided into a flow stabilization zone and a feeding zone 16. The gap between the upper end of the partition 19 and the top of the tank 1 forms an overflow port, and the upper end of the partition 19 is lower than the lowest point of the inlet of the liquid outlet channel 30. This design effectively reduces turbulence in the liquid flow and ensures the stability of the liquid flow. The partition 19 not only realizes the functional zoning of the tank 1, but also optimizes the liquid flow path by controlling the height of the overflow port, reducing turbulence in the liquid flow process, thereby improving the working efficiency of the overflow tank and the uniformity of liquid treatment.
[0045] Preferably, in one embodiment, only one set of the rectifier tank section is provided. The flow stabilization zone is provided with a first partition 17 and a second partition 18, thereby dividing the flow stabilization zone into an inlet tank section 10, a first tank section 12, and a second tank section 13. The first partition 17 is fixed to the bottom of the tank body 1 and is lower than the top of the tank body 1 to form the first upper outlet 11. The second partition 18 is fixed to the top of the tank body 1, and there is a gap between the bottom of the second partition 18 and the bottom of the tank body 1 to form a lower outlet 14. In other embodiments, multiple sets of rectifier tank section groups can be provided to further reduce turbulence during liquid flow.
[0046] Furthermore, in some embodiments, the depth of the lower outlet 14 is greater than or equal to the width of the first tank segment 12.
[0047] Specifically, the depth of the lower outlet 14 can be achieved by adjusting the structural design of the tank 1, for example, by precisely controlling the machining dimensions of the tank 1 during manufacturing. Alternatively, the depth of the lower outlet 14 can also be achieved by setting adjustable baffles or partitions, allowing for flexible adjustment of the depth according to actual needs. As a preferred embodiment, the depth of the lower outlet 14 can be equal to the width of the first tank section 12 to ensure an increased flow channel area, thereby reducing the Reynolds number and minimizing turbulence.
[0048] This application, by specifying that the depth of the lower outlet 14 is greater than or equal to the width of the first channel section 12, effectively increases the flow channel area, thereby reducing the Reynolds number, decreasing turbulence, and ensuring that the liquid maintains a stable flow state when flowing from the first channel section 12 to the second channel section 13. This design avoids liquid flow instability caused by insufficient depth of the lower outlet 14, thus reducing turbulence and improving the uniformity and controllability of liquid flow.
[0049] Furthermore, in some embodiments, the width of the second slot segment 13 is greater than or equal to the width of the first slot segment 12.
[0050] Specifically, the width of the second channel segment 13 can be achieved in various ways. For example, the width of the second channel segment 13 can be designed to be the same as or slightly larger than the first channel segment 12. As a preferred embodiment, the width of the second channel segment 13 can be designed to be 1.2 to 1.5 times the width of the first channel segment 12 to ensure that the liquid can maintain smooth flow when flowing through the second channel segment 13. In addition, the width of the second channel segment 13 can also be adjusted according to the liquid flow rate and velocity in the actual application scenario to further optimize the flow effect.
[0051] This application increases the width of the second channel section 13, thereby increasing the flow area, reducing the Reynolds number, and minimizing turbulence. This ensures smooth flow of liquid as it passes through the second channel section 13, avoiding problems such as liquid stagnation or poor flow caused by insufficient channel width. This design helps improve the flow efficiency of liquid in the overflow channel, ensuring that materials can smoothly pass through the overflow channel and enter the next process.
[0052] Furthermore, in some embodiments, the widths of the first tank segment 12 and the second tank segment 13 are both greater than or equal to the width of the liquid inlet tank segment 10.
[0053] The widths of the first tank section 12 and the second tank section 13 can be set to 1.2 to 1.5 times the width of the inlet tank section 10 to further optimize the flow channel area. As a preferred embodiment, the width of the first tank section 12 can be equal to the width of the second tank section 13 to ensure more uniform liquid flow within the tank 1. Furthermore, the widths of the first tank section 12 and the second tank section 13 can be adjusted according to actual needs; for example, when the liquid flow rate is high, the width can be appropriately increased to reduce the Reynolds number and decrease turbulence.
[0054] This application effectively increases the flow channel area by setting the width of the first channel section 12 and the second channel section 13 to be greater than or equal to the width of the liquid inlet channel section 10, thereby reducing the Reynolds number and turbulence. This design helps ensure a more uniform flow of liquid within the tank 1, reducing irregularities in liquid flow, thus preventing material from being carried into the bottom of the overflow tank or dead zones, reducing material retention, and improving hygiene and product quality. Specifically, due to the increased flow channel area, the flow velocity of the liquid within the tank 1 is reduced, thereby reducing turbulence and making the liquid flow more stable.
[0055] Furthermore, in some embodiments, the depth of the lower outlet 14 is greater than or equal to the depth of the first upper outlet 11.
[0056] The depth of the lower outlet 14 can be achieved by adjusting the structural design of the tank 1, for example, by precisely controlling the machining dimensions of the tank 1 during manufacturing. As a preferred embodiment, the depth of the lower outlet 14 can be achieved by installing an adjustable baffle inside the tank 1, thereby flexibly adjusting the depth of the lower outlet 14 according to actual needs.
[0057] By increasing the depth of the lower outlet 14, sufficient depth is ensured for the liquid to flow inside the tank 1, thereby increasing the flow channel area, reducing the Reynolds number, reducing turbulence, and thus reducing instability in the liquid flow process.
[0058] Furthermore, in some embodiments, the cross-sectional area of the liquid inlet channel 20 gradually increases toward the tank body 1.
[0059] Specifically, the cross-sectional area of the inlet channel 20 can be gradually increased in several ways. For example, the inlet channel 20 can be designed as a conical section, with its cross-sectional area gradually increasing from the inlet to the outlet; or, the inlet channel 20 can adopt a stepped design, with each segment having a larger cross-sectional area than the previous segment; in addition, the inlet channel 20 can also achieve a gradual increase in cross-sectional area through a curved transition. These design methods can effectively increase the channel area, thereby reducing the Reynolds number and causing the liquid to gradually slow down when entering the tank 1, making the liquid flow in the tank 1 more uniform and controllable.
[0060] In a preferred embodiment, the conical section can be achieved by adjusting the inclination angle of the inner wall of the flow channel. For example, the inclination angle of the inner wall of the flow channel can be between 5 and 15 degrees to ensure the smoothness of the liquid flow. In addition, the length of the conical section can be adjusted according to actual needs. For example, the length of the conical section can be set to 1 / 3 to 1 / 2 of the total length of the liquid inlet flow channel 20 to optimize the liquid flow effect.
[0061] Furthermore, in some embodiments, the liquid outlet channel 30 is an inclined channel.
[0062] Specifically, the design of the inclined flow channel can be achieved in several ways. For example, the inclination angle of the inclined flow channel can be adjusted according to the flow characteristics of the liquid material to ensure that the liquid is drawn out of the tank 1 in a laminar flow manner. As a preferred embodiment, the inclination angle of the inclined flow channel can be between 10° and 30°, which can effectively reduce the irregularity of the liquid flow. In addition, the cross-sectional area of the inclined flow channel can also gradually decrease in the direction away from the tank 1 to further optimize the stability of the liquid flow.
[0063] The inclined flow channel design helps the liquid to exit the tank 1 in a laminar flow manner, reducing the irregularity of the liquid flow, thereby preventing spherical or blocky materials from being carried into the bottom of the overflow tank or dead zone, reducing long-term material retention, and improving hygiene and product quality.
[0064] Furthermore, in some embodiments, the cross-sectional area of the inclined channel gradually decreases in the direction away from the tank 1.
[0065] Specifically, the cross-sectional area of the inclined flow channel can be gradually reduced in various ways, such as by using a tapered design, so that the width or height of the flow channel gradually decreases from the end closer to the tank 1 to the end farther away from the tank 1. As a preferred embodiment, the cross-sectional area of the inclined flow channel can decrease linearly, that is, the width or height of the flow channel decreases uniformly. Another possible implementation is to use a non-linear reduction, for example, the width or height of the flow channel decreases according to a specific curve, to adapt to different liquid flow requirements. In addition, the material of the inclined flow channel can be selected to be corrosion-resistant and wear-resistant to ensure stable performance during long-term use.
[0066] By gradually reducing the cross-sectional area of the inclined flow channel away from the tank 1, it helps to control the flow rate and volume of the liquid, ensuring the stability of the liquid flow in the channel.
[0067] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
