Description
Technical Field
[0001] The utility model relates to the technical field of homogenizer accessories, in particular to a feeding tank with coil pipe cooling. Background Art
[0002] The test homogenizer includes a feeding tank. Materials enter the hydraulic end of the homogenizer from the feeding tank and then return to the feeding tank to complete a cycle of the materials. During the circulating flow process of the materials, the temperature rises rapidly due to friction, and the material temperature is likely to exceed the process requirements, affecting the accuracy of the test. To ensure the accuracy of the test, a cooling structure needs to be provided in the feeding tank.
[0003] Please refer to the attached Figure 1 , the cooling structure of the feeding tank of the prior art homogenizer consists of a hopper 1, an outer jacket 2, a medium outlet joint 3, a medium inlet joint 4, a material outlet joint 5, a U-shaped pipe 6, and a hose 7. The hopper 1 is installed on the top of the feeding tank, the outer jacket 2 is sleeved outside the feeding tank and welded, the medium outlet joint 3 and the medium inlet joint 4 are welded on the outer jacket 2, the material outlet joint 5 is welded at the bottom of the hopper 1, one end of the hose 7 is connected to the hydraulic end of the homogenizer, and the other end of the hose 7 is connected to the hopper 1 through the U-shaped pipe 6.
[0004] The flow process of the materials in the prior art is as follows: The materials are first added into the hopper 1, enter the hydraulic end of the homogenizer from the material outlet joint 5, and after homogenization, return to the hopper 1 through the hose 7 and the U-shaped pipe 6. The flow process of the cooling medium is as follows: The cooling medium enters the outer jacket 2 from the medium inlet joint 4 at the bottom of the outer jacket 2 and then flows out from the medium outlet joint 3 at the top of the outer jacket 2.
[0005] The cooling of the materials is achieved through the heat exchange between the outer jacket 2 and the feeding tank. The contact area between the outer jacket 2 and the feeding tank is small, the cooling effect is poor, and the cooling of the materials located in the middle and at the edge of the feeding tank is uneven. Therefore, a feeding tank with coil pipe cooling is needed to solve the problem of poor cooling effect of the feeding tank cooling structure in the prior art. Summary of the Invention
[0006] The purpose of the utility model is to provide a feeding tank with coil pipe cooling, which can solve the problem of poor cooling effect of the feeding tank cooling structure in the prior art.

[0008] A feed tank with coil cooling, comprising a hopper, an outer jacket, a medium inlet joint, a medium outlet joint, a material outlet joint, a hose, a coil and a feed tank; the hopper is installed at the upper end of the feed tank, and the bottom of the feed tank is communicated with the hydraulic end of the homogenizer through the material outlet joint; the outer jacket is sleeved outside the feed tank, the medium outlet joint is installed at the top of the outer jacket, and the medium inlet joint is installed at the bottom of the outer jacket; the coil is wound and arranged in the cavity between the outer wall of the feed tank and the inner wall of the outer jacket, the hydraulic end of the homogenizer is communicated with one end of the coil, the other end of the coil is communicated with one end of the hose through a coil outlet joint, and the other end of the hose is communicated with the top of the hopper through a U-shaped pipe.
[0009] A high-pressure hose is connected between the hydraulic end of the homogenizer and one end of the coil. One end of the high-pressure hose is communicated with the coil through a coil inlet joint, and the other end of the high-pressure hose is communicated with the hydraulic end of the homogenizer.
[0010] One end of the coil is located at one side of the bottom of the feed tank, and the other end of the coil is wound from the bottom of the feed tank to the top of the feed tank and then extends downward to the bottom of the feed tank.
[0011] The outer jacket is a heat-insulating jacket, and the width of the gap between the inner wall of the outer jacket and the outer wall of the feed tank is greater than the outer diameter of the coil.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. Since the utility model is provided with a coil, which is spirally arranged between the outer jacket and the feed tank, and the material is conveyed by the spiral path, the heat exchange area, path length and time between the material and the cooling medium are greatly increased, so that the cooling uniformity and cooling efficiency of the material are greatly improved, and thus it is beneficial to improve the accuracy of the material homogenization test.
[0014] 2. Since the utility model is provided with a high-pressure hose, the material in the hydraulic end of the homogenizer is pumped into the coil through the high-pressure hose, and can be spirally conveyed upward from the bottom of the coil to the top and then fall back into the hose at the bottom, realizing the smooth and circulating flow of the material, and ensuring the full cooling of the material while not affecting the material homogenization process. Description of the Drawings
[0015] Figure 1 is a schematic structural diagram of a feed tank in the prior art;
[0016] Figure 2 is a schematic structural diagram of the feed tank with coil cooling of the utility model.
[0017] In the figure, 1 is a hopper, 2 is an outer jacket, 3 is a medium outlet joint, 4 is a medium inlet joint, 5 is a material outlet joint, 6 is a U-shaped tube, 7 is a hose, 8 is a coil pipe, 801 is a coil pipe outlet joint, 802 is a coil pipe inlet joint, 9 is a feed tank, 10 is the hydraulic end of a homogenizer, and 11 is a high-pressure hose. Detailed implementation mode
[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0019] Please refer to the attached Figure 2 , a feed tank with coil pipe cooling, comprising a hopper 1, an outer jacket 2, a medium outlet joint 3, a medium inlet joint 4, a material outlet joint 5, a hose 7, a coil pipe 8 and a feed tank 9; the hopper 1 is installed at the upper end of the feed tank 9, and the bottom of the feed tank 9 is communicated with the hydraulic end 10 of the homogenizer through the material outlet joint 5; the outer jacket 2 is sleeved outside the feed tank 9, the medium outlet joint 3 is installed at the top of the outer jacket 2, and the medium inlet joint 4 is installed at the bottom of the outer jacket 2; the coil pipe 8 is spirally arranged in the cavity between the outer wall of the feed tank 9 and the inner wall of the outer jacket 2, the hydraulic end 10 of the homogenizer is communicated with one end of the coil pipe 8, the other end of the coil pipe 8 is communicated with one end of the hose 7 through the coil pipe outlet joint 801, and the other end of the hose 7 is communicated with the top of the hopper 1 through the U-shaped tube 6.
[0020] Through the arrangement of the coil pipe 8 in the cavity between the feed tank 9 and the outer jacket 2, the coil pipe 8 is used to convey materials, so that when the materials flow through the coil pipe 8, the contact area and contact path length between the materials and the cooling medium in the cavity are greatly increased, and the time of the cooling process is increased, thereby effectively improving the cooling effect on the materials.
[0021] The cooling medium enters the outer jacket 2 through the medium inlet joint 4, and flows out from the medium outlet joint 3 after fully contacting the coil pipe 8 between the feed tank 9 and the outer jacket 2. The smaller the diameter of the coil pipe 8, the better the heat exchange effect between the materials and the cooling medium through the coil pipe 8, that is, the better the cooling uniformity and cooling efficiency. The diameter of the coil pipe 8 is adaptively set according to the smooth flow requirement of the materials.
[0022] The present utility model only changes the flow mode of the materials, and the flow homogenization process of the materials is the same as that of the prior art, which will not be elaborated here.
[0023] A high-pressure hose 11 is connected between the hydraulic end 10 of the homogenizer and one end of the coil pipe 8. One end of the high-pressure hose 11 is communicated with the coil pipe 8 through the coil pipe inlet joint 802, and the other end of the high-pressure hose 11 is communicated with the hydraulic end 10 of the homogenizer through a boosting device.
[0024] Preferably, a pressurizing device such as a booster pump can be used to transport the material at the hydraulic end 10 of the homogenizer into the high-pressure hose 11, so that the material enters the coil 8 with a relatively small diameter through the coil inlet joint 802 via the high-pressure hose 11, and the pressure is used to ensure the spiral flow of the material in the coil 8. The pressurizing pressure can be adaptively set according to the flow requirements of the material.
[0025] One end of the coil 8 is located on one side of the bottom of the feed tank 9, and the other end of the coil 8 spirally winds from the bottom of the feed tank 9 to the top of the feed tank 9 and then extends downward to the bottom of the feed tank 9.
[0026] Since the hydraulic end 10 of the homogenizer is located below the feed tank 9, the material can enter the bottom of the coil 8 after homogenization, extend spirally from the bottom to the top through the coil 8, and finally flow back downward from the top to the hose 7, maximizing the flow path of the material in the coil 8, increasing the cooling contact area, prolonging the cooling time, and improving the cooling effect.
[0027] The jacket 2 is a heat-insulating jacket, and the gap width between the inner wall of the jacket 2 and the outer wall of the feed tank 9 is greater than the outer diameter of the coil 8.
[0028] The jacket 2 can be made of a material with good heat-insulating performance, or heat-insulating material can be wrapped around the outside of the jacket 2 to achieve the heat-insulating effect, so as to ensure the sufficient heat exchange between the cooling medium and the coil 8. Enough gaps should be reserved between the inner diameter of the jacket 2 and the outer wall of the feed tank 9 to ensure the spiral installation of the coil 8 and accommodate enough cooling medium to ensure the cooling effect.
[0029] Please refer to the attached Figure 2 , the working process and working principle of the present utility model are as follows:
[0030] The flow process of the material is as follows: The material is first added to the hopper 1, and the material enters the hydraulic end 10 of the homogenizer from the material outlet joint 5. After being homogenized by the homogenizer, it enters the coil 8 through the high-pressure hose 11 via the coil inlet joint 802. During the process of the material spirally rising through the coil 8, heat exchange is carried out between the coil 8 and the cooling medium. The heat exchange contact area is large and the path is long, so as to fully cool the material. After the material spirals to the top of the feed tank 9, it then flows downward to the bottom of the feed tank 9, enters the hose 7 through the coil outlet joint 801, and finally returns to the hopper 1 through the U-shaped tube 6 to complete a cycle process.
[0031] The flow process of the cold zone medium is as follows: The cooling medium enters the cavity between the outer wall of the feed tank 9 and the inner wall of the jacket 2 through the medium inlet joint 4, and the cooling medium contacts the coil 8 to achieve heat exchange, and then flows out through the medium outlet joint 3.
[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
