Description
Technical Field
[0001] The present application relates to the technical field of chemical manufacturing, and more particularly, to a stirring tank. Background Art
[0002] Stirring in existing stirring tanks is usually achieved by setting a motor to drive a rotating shaft with blades. The manufacturing cost and maintenance cost of such stirring tanks are relatively high. Especially in the technical field of chemical manufacturing, various corrosive materials are usually encountered, which requires additional consideration of the anti-corrosion performance of key functional devices such as blades and rotating shafts, resulting in a further increase in the use cost of the stirring tank. Summary of the Utility Model
[0003] The purpose of the present application is to provide a stirring tank, which has the advantages of low use cost and easy maintenance.
[0004] The embodiments of the present application are implemented as follows:
[0005] The embodiments of the present application provide a stirring tank, which includes a tank body, an inserted bottom pipe, a spoiler, and a vortex breaker. A fixed joint is provided at the top cover of the tank body. The fixed joint includes an outer joint located outside the tank body and an inner joint located inside the tank body. The outer joint and the inner joint are connected, and the outer joint is connected to the lower end of the tank body through the circulation pipeline of the tank body; the inserted bottom pipe is located inside the tank body, the feeding end of the inserted bottom pipe is connected to the fixed joint, and a liquid outlet is provided on the outer peripheral wall of the inserted bottom pipe; the spoiler protrudes from the inner wall of the tank body and extends along the height direction of the tank body; the vortex breaker is located at the bottom wall of the tank body.
[0006] In the above technical solution, the feeding end of the inserted bottom pipe is connected to the circulation pipeline of the tank body through the fixed joint, and the liquid outlet of the inserted bottom pipe is provided on the outer peripheral wall of the inserted bottom pipe. At the same time, a spoiler and a vortex breaker are added inside the tank body; among them, the feeding end of the inserted bottom pipe is connected to the circulation pipeline of the tank body, so that part of the materials in the tank body can continuously flow out from the liquid outlet of the inserted bottom pipe (equivalent to a power unit); the spoiler protrudes from the inner wall of the tank body and extends along the height direction of the tank body. The materials continuously flowing out from the liquid outlet will form a turbulent flow when flushing on the spoiler, thereby realizing the stirring and mixing of the materials; the vortex breaker is arranged at the bottom wall of the tank body, which can prevent the materials from forming a vortex in the tank body (the formation of a vortex will affect the stirring effect), increase the turbulence and oxygen mass transfer, thereby improving the stirring and mixing effect of the materials. By connecting the feeding end of the inserted bottom pipe to the circulation pipeline of the tank body, providing the liquid outlet of the inserted bottom pipe on the outer peripheral wall of the inserted bottom pipe, and adding a spoiler and a vortex breaker inside the tank body, the present application can realize the stirring and mixing of the materials in the tank body. Compared with the method of setting a motor to drive a rotating shaft with blades for stirring in the tank body, the overall structure of the stirring solution provided by the embodiments of the present application is simpler and the volume of related devices is smaller, having the advantages of low use cost and easy maintenance.
[0007] In some alternative embodiments, the extension direction of the axis of the liquid outlet passes through the spoiler.
[0008] In the above technical solution, the extension direction of the axis of the liquid outlet passes through the spoiler, that is, the material coming out of the liquid outlet can directly impact the spoiler, so that the spoiler can play a better spoiler effect, thereby improving the stirring and mixing effect of the material.
[0009] In some alternative embodiments, along the radial direction of the tank body, the size of the spoiler in the circumferential direction of the tank body gradually decreases.
[0010] In the above technical solution, along the radial direction of the tank body, the size of the spoiler in the circumferential direction of the tank body is set to gradually decrease, so that the spoiler has a greater shearing force on the material, thereby being able to play a better spoiler effect.
[0011] In some alternative embodiments, the spoiler includes a first plate body and a second plate body that are connected to form an included angle. One side of the first plate body away from the second plate body is connected to the inner wall of the tank body, and one side of the second plate body away from the first plate body is connected to the inner wall of the tank body.
[0012] In the above technical solution, the spoiler includes a first plate body and a second plate body that are connected to form an included angle, so that the side of the spoiler close to the liquid outlet is relatively sharp, which can further increase the shearing force of the spoiler on the material, thereby further improving the spoiler effect of the spoiler.
[0013] In some alternative embodiments, the included angle between the first plate body and the second plate body is 20 - 45°.
[0014] In the above technical solution, the angle of the included angle is limited within a specific range, so that the spoiler has a more appropriate shearing force on the material, thereby being able to play a better spoiler effect.
[0015] In some alternative embodiments, in the radial direction of the tank body, the ratio of the size of the spoiler to the inner diameter of the tank body is 1:(6 - 8).
[0016] In the above technical solution, in the radial direction of the tank body, the ratio of the size of the spoiler to the inner diameter of the tank body is limited within a specific range, so that the spoiler has a more appropriate protruding size on the inner wall of the tank body, thereby being able to play a better spoiler effect.
[0017] In some alternative embodiments, a plurality of spoilers are provided, and the plurality of spoilers are spaced apart along the circumferential direction of the tank body.
[0018] In the above technical solution, a plurality of spoilers spaced apart along the circumferential direction of the tank body are provided. Through the combined action of the plurality of spoilers, a better spoiler effect can be achieved, thereby improving the stirring and mixing effect of the material.
[0019] In some alternative embodiments, the bottom-inserted pipe is provided with a plurality of liquid outlets, the number of the liquid outlets is not greater than that of the spoiler plates, and the extending directions of the axes of the plurality of liquid outlets respectively pass through different spoiler plates.
[0020] In the above technical solution, a plurality of liquid outlets are provided on the bottom-inserted pipe and each liquid outlet is aligned with a spoiler plate at a different position, that is, the materials coming out of the plurality of liquid outlets can directly impact the spoiler plates at different positions, which helps to improve the stirring and mixing effect of the materials.
[0021] In some alternative embodiments, in the radial direction of the tank body, the bottom-inserted pipe is located between the center of the tank body and the inner wall of the tank body.
[0022] In the above technical solution, setting the bottom-inserted pipe at a non-central position of the tank body can effectively prevent the generation of eddy currents, thereby improving the stirring and mixing effect of the materials.
[0023] In some alternative embodiments, the vortex breaker is located at the center of the bottom wall of the tank body.
[0024] In the above technical solution, setting the vortex breaker at the center of the bottom wall of the tank body can achieve a better vortex-breaking effect, thereby improving the stirring and mixing effect of the materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following specifically describes a mixing tank of this application.
[0037] Refer toFigure 1 and Figure 2 In an embodiment of the present application, a stirring tank 10 is provided, which includes a tank body 100, an inserted bottom pipe 200, a spoiler 300, and a vortex breaker 400. A fixed joint 111 is provided at the top cover 110 of the tank body 100. The fixed joint 111 includes an outer joint 111a located outside the tank body 100 and an inner joint 111b located inside the tank body 100. The outer joint 111a and the inner joint 111b are communicated. The outer joint 111a is communicated with the lower end of the tank body 100 through a circulation pipeline (not shown in the figure) of the tank body 100; the inserted bottom pipe 200 is located inside the tank body 100. The feeding end of the inserted bottom pipe 200 is communicated with the fixed joint 111, and a liquid outlet 210 is opened on the outer peripheral wall of the inserted bottom pipe 200; the spoiler 300 protrudes from the inner wall of the tank body 100 and extends along the height direction of the tank body 100; the vortex breaker 400 is located at the bottom wall of the tank body 100.
[0038] In the present application, the feeding end of the inserted bottom pipe 200 is communicated with the circulation pipeline of the tank body 100 through the fixed joint 111, and the liquid outlet 210 of the inserted bottom pipe 200 is opened on the outer peripheral wall of the inserted bottom pipe 200. At the same time, a spoiler 300 and a vortex breaker 400 are added inside the tank body 100. Among them, the feeding end of the inserted bottom pipe 200 is communicated with the circulation pipeline of the tank body 100, so that a part of the material in the tank body 100 can continuously flow out from the liquid outlet 210 of the inserted bottom pipe 200 (equivalent to a power unit); the spoiler 300 protrudes from the inner wall of the tank body 100 and extends along the height direction of the tank body 100. The material continuously flowing out from the liquid outlet 210 will form a turbulent flow when washing on the spoiler 300, thereby realizing the stirring and mixing of the material; the vortex breaker 400 is arranged at the bottom wall of the tank body 100, which can prevent the material from forming a vortex in the tank body 100 (the formation of a vortex will affect the stirring effect), increase the turbulence and oxygen mass transfer, thereby improving the stirring and mixing effect on the material. In the present application, by communicating the feeding end of the inserted bottom pipe 200 with the circulation pipeline of the tank body 100, opening the liquid outlet 210 of the inserted bottom pipe 200 on the outer peripheral wall of the inserted bottom pipe 200, and adding a spoiler 300 and a vortex breaker 400 inside the tank body 100 at the same time, the stirring and mixing of the material in the tank body 100 can be realized. Compared with the method of setting a motor-driven rotating shaft with blades in the tank body 100 for stirring, the overall structure of the stirring scheme provided by the embodiment of the present application is simpler and the volume of related devices is smaller, having the advantages of lower use cost and easy maintenance.
[0039] It should be noted that in the field of chemical manufacturing technology, in order to prevent materials from depositing in the tank body 100, the chemical tank body 100 usually comes with a circulation pipeline (generally, a pipeline with a power pump is set to first extract the materials in the tank body 100 from the tank body 100, and then transport the extracted materials back to the tank body 100 from the top of the tank body 100 to achieve the circulation of the materials). In the embodiments of the present application, the circulation pipeline will not be introduced in detail, and specific settings can be made according to the conventional selection in this field.
[0040] It should be noted that the number of the bottom insertion pipes 200 is not limited and can be adjusted according to the size of the tank body 100 and actual needs. For example, if the volume of the tank body 100 is small, only one or two bottom insertion pipes 200 can be set; if the volume of the tank body 100 is large, four or five bottom insertion pipes 200 can be set.
[0041] It should be noted that the connection mode between the feed end of the bottom insertion pipe 200 and the inner joint 111b is not limited. For example, it can be connected through an adapter.
[0042] As an example, the extending direction of the axis of the liquid outlet 210 passes through the spoiler 300.
[0043] In this embodiment, the extending direction of the axis of the liquid outlet 210 passes through the spoiler 300, that is, the materials coming out of the liquid outlet 210 can directly impact the spoiler 300, so that the spoiler 300 can play a better flow disturbing effect, thereby improving the stirring and mixing effect on the materials.
[0044] In other possible embodiments, the extending direction of the axis of the liquid outlet 210 may not pass through the spoiler 300 either.
[0045] It should be noted that the specific configuration of the spoiler 300 is not limited and can be adjusted according to actual needs (for example, the spoiler 300 can be a solid structure or a hollow structure), as long as it can play a flow disturbing effect.
[0046] Refer to Figure 3 , as an example, along the radial direction of the tank body 100, the size of the spoiler 300 in the circumferential direction of the tank body 100 gradually decreases.
[0047] In this embodiment, along the radial direction of the tank body 100, the size of the spoiler 300 in the circumferential direction of the tank body 100 is set to gradually decrease, so that the spoiler 300 has a greater shear force on the materials, thereby being able to play a better flow disturbing effect.
[0048] Refer to Figure 3, as an example, the spoiler 300 includes a first plate body 310 and a second plate body 320 that are connected to form an included angle. One side of the first plate body 310 away from the second plate body 320 is connected to the inner wall of the tank body 100, and one side of the second plate body 320 away from the first plate body 310 is connected to the inner wall of the tank body 100.
[0049] In this embodiment, the spoiler 300 includes a first plate body 310 and a second plate body 320 that are connected to form an included angle, so that one side of the spoiler 300 close to the liquid outlet 210 is relatively sharp, which can further improve the shearing force of the spoiler 300 on the material, and thus further improve the flow disturbing effect of the spoiler 300.
[0050] It should be noted that the angle of the included angle is not limited. For example, it can be an acute angle, a right angle, or an obtuse angle, and can be specifically adjusted according to actual needs.
[0051] As an example, the included angle between the first plate body 310 and the second plate body 320 is 20 to 45°, for example but not limited to any one of the point values of 20°, 25°, 30°, 35°, 40° and 45° or the range values between any two of them.
[0052] In this embodiment, the angle of the included angle is limited within a specific range so that the spoiler 300 has a more suitable shearing force on the material, and thus can exert a better flow disturbing effect.
[0053] It can be understood that the protruding size of the spoiler 300 on the inner wall of the tank body 100 is closely related to the flow disturbing effect it can exert. Based on this, the protruding size of the spoiler 300 on the inner wall of the tank body 100 can be limited.
[0054] As an example, in the radial direction of the tank body 100, the ratio of the size of the spoiler 300 to the inner diameter of the tank body 100 is 1:(6 - 8), for example but not limited to any one of the point values of 1:6, 1:6.5, 1:7, 1:7.5 and 1:8 or the range values between any two of them.
[0055] In this embodiment, in the radial direction of the tank body 100, the ratio of the size of the spoiler 300 to the inner diameter of the tank body 100 is limited within a specific range so that the spoiler 300 has a more suitable protruding size on the inner wall of the tank body 100, and thus can exert a better flow disturbing effect.
[0056] Refer to Figure 1 , as an example, a plurality of spoilers 300 are provided, and the plurality of spoilers 300 are distributed at intervals along the circumferential direction of the tank body 100.
[0057] In this embodiment, a plurality of spoiler plates 300 are arranged at intervals along the circumferential direction of the tank body 100. Through the combined action of the plurality of spoiler plates 300, a better flow disturbance effect can be achieved, thereby improving the stirring and mixing effect of the material.
[0058] It should be noted that the specific number of the spoiler plates 300 is not limited and can be adjusted according to actual needs. For example, it can be three, four or five.
[0059] As an example, the bottom insertion pipe 200 is provided with a plurality of liquid outlets 210, and the number of the liquid outlets 210 is not greater than the number of the spoiler plates 300. The extending directions of the axes of the plurality of liquid outlets 210 respectively pass through different spoiler plates 300.
[0060] In this embodiment, a plurality of liquid outlets 210 are provided on the bottom insertion pipe 200 and each liquid outlet 210 is aligned with the spoiler plates 300 at different positions, that is, the materials coming out of the plurality of liquid outlets 210 can directly impact the spoiler plates 300 at different positions, which helps to improve the stirring and mixing effect of the materials.
[0061] In other possible embodiments, it can also be that only one liquid outlet 210 is provided on one bottom insertion pipe 200.
[0062] It should be noted that the shape and size of the liquid outlet 210 are not limited and can be adjusted according to actual needs.
[0063] Refer to Figure 1 , as an example, in the radial direction of the tank body 100, the bottom insertion pipe 200 is located between the center of the tank body 100 and the inner wall of the tank body 100.
[0064] In this embodiment, by arranging the bottom insertion pipe 200 at a non - central position of the tank body 100, the generation of vortex can be effectively prevented, thereby improving the stirring and mixing effect of the material.
[0065] Refer to Figure 1 , as an example, the vortex breaker 400 is located at the center of the bottom wall of the tank body 100.
[0066] In this embodiment, by arranging the vortex breaker 400 at the center of the bottom wall of the tank body 100, a better vortex breaking effect can be achieved, thereby improving the stirring and mixing effect of the material.
[0067] It should be noted that for the structural or functional units in the mixing tank 10 that are not specifically described or limited, they can be set according to the conventional selection in the art.
[0068] As an example, the bottom insertion pipe 200 is made of corrosion - resistant PP or PVC material.
[0069] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
