Description

Technical Field

[0001] This utility model relates to the field of concentrated liquid filling, and more specifically, to a double-sided liquid inlet and return type filling and storage circulation tank. Background Technology

[0002] In traditional concentrated liquid filling processes, the concentrated liquid is transported into the concentrated liquid packaging container through pipelines, and a sanitary pump drives the liquid to enter the bottle under pressure. However, when the pressure is low or the voltage fluctuates, or when the amount of concentrated liquid entering the pipeline is small, it is difficult for the concentrated liquid to collect at the outlet. This results in poor discharge of the last small amount of concentrated liquid from the packaging container each time, unstable filling volume, and easy liquid residue, leading to wasted costs.

[0003] To address the aforementioned issues, patent application CN202322423808.8 describes a filling and storage circulation tank. This tank improves the tank structure to enhance the recovery rate of the concentrate, ensure stable filling volume, and reduce liquid residue. However, in practical use, we found that tilting the circulation tank leads to no liquid in the side output pipe. Furthermore, since both the inlet and outlet pipes are located above the circulation tank, the manual drain diaphragm valve can only open for automatic draining when the tank pressure exceeds the pipe pressure. Additionally, this technical solution uses a single return pipe; if the diaphragm valve malfunctions, backflow problems arise, posing a risk. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided liquid inlet and return type filling and storage circulation tank, which can improve the problems of liquid not coming out of the filling nozzle and avoid backflow failure in existing circulation tanks.

[0005] The embodiments of this utility model are implemented as follows:

[0006] A double-sided liquid inlet and return type filling and storage circulation tank includes: a circulation tank body and a filter screen disposed inside the circulation tank body. The circulation tank body consists of a cylindrical tank body in the middle and hemispherical seals disposed at both ends of the cylindrical tank body. Multiple filling nozzles are evenly spaced at the bottom of the cylindrical tank body. Liquid inlet ports are provided at the bottom of the two hemispheres at both ends, and the liquid inlet ports are connected to a one-to-two liquid inlet pipeline. Return ports are provided at the top of the two hemispheres at both ends, and the return ports are connected to a two-in-one return pipeline. Two sets of breathing components are provided at the top two ends of the cylindrical tank body. The filter screen is assembled at both ends of the cylindrical tank body. The mesh density of the filter screen gradually decreases from the return port to the inlet port. The filter screen has an overall arc-shaped structure and is concave towards the cylindrical tank body.

[0007] In a preferred embodiment of the present invention, the above-mentioned filling and storage circulation tank further includes a fishbone positioning frame. Fasteners for fixing the circulation tank body are provided at both ends of the fishbone positioning frame. The middle part of the fishbone positioning frame is fishbone shaped and is provided with a positioning notch for positioning and penetration of the filling nozzle. The fishbone positioning frame is welded to the filling equipment.

[0008] In a preferred embodiment of this utility model, the fastener includes a shock-absorbing platform and an adjusting screw. The upper part of the shock-absorbing platform is provided with a flange for connecting the circulating tank, and the bottom of the shock-absorbing platform is provided with two sets of threaded grooves. The threaded grooves of the fishbone positioning frame are provided with hollow guide posts with internal threads at the corresponding holes. The hollow guide posts are inserted into the threaded grooves. The adjusting screw is inserted from the through hole below the guide post of the fishbone positioning frame, and a fastening nut is mounted on the adjusting screw.

[0009] In a preferred embodiment of this utility model, the filter screen and the cylindrical tank are detachably connected.

[0010] In a preferred embodiment of this utility model, the filter screen is provided with three aperture sizes, which are successively divided by a circle with a radius of 1 / 4 hemisphere, a circle with a radius of 1 / 2 hemisphere, and a circle with a radius of one hemisphere, forming a filter screen with an increased aperture size.

[0011] In a preferred embodiment of this utility model, a first automatic diaphragm valve is provided on the two-way inlet pipeline, and a second automatic diaphragm valve is provided on the two-way return pipeline.

[0012] In a preferred embodiment of this utility model, a spray ball is provided at the liquid inlet.

[0013] The beneficial effects of this utility model embodiment are:

[0014] 1. The improved filling and storage circulation tank has changed the original inlet and outlet pipelines and methods. The original top inlet has been changed to simultaneous inlet from both ends of the bottom of the circulation tank. When the circulation tank is tilted, it will not cause the filling nozzles on the side to have no concentrated liquid output. At the same time, compared with the original single pipeline relying on pressure for liquid return, it has been redesigned to return from the top of both sides of the circulation tank. This means that when the diaphragm valve malfunctions and the return on one side fails, the other side can still continue to operate.

[0015] 2. The filtration device inside the circulating tank has been improved. A concave arc-shaped filter screen is installed between the hemispherical and cylindrical tank bodies, which allows impurities to be retained in the spherical space formed by the hemispherical body and the filter screen when liquid is fed in. In addition, in case of tilting, the mesh density of the filter screen gradually decreases from the return pipe to the inlet pipe, so that the filter screen has a certain capacity for storing concentrate, thereby further preventing the filling nozzle on the tilted side from having no concentrate output.

[0028] First Embodiment

[0029] Please refer to Figure 1-4 This embodiment provides a double-sided liquid inlet and return type filling and storage circulation tank. The filling and storage circulation tank includes: a circulation tank body 110, a filter screen 120 disposed in the circulation tank body 110, and a fishbone positioning frame 130 for fixing the circulation tank body 110.

[0030] This embodiment addresses the issue of the filling nozzle 111 not dispensing concentrate due to tilting of the filling and storage circulation tank caused by environmental or assembly reasons during actual use. The structure of the circulation tank body 110 has been improved.

[0031] The circulation tank body 110 is formed by a central cylindrical tank 112 and hemispherical bodies 113 at both ends of the cylindrical tank 112, which are sealed together. The cylindrical tank 112 is designed to be cylindrical with an arc-shaped bottom, allowing the concentrated liquid inside the circulation tank body 110 to smoothly enter the filling nozzle 111. Multiple filling nozzles 111 are evenly spaced at the bottom of the cylindrical tank 112. Each filling nozzle 111 is also equipped with a manual drain assembly, which is connected to one of the filling nozzles. The manual drain assembly includes a manual drain diaphragm valve, which is connected to the circulation tank body 110 via a differential pressure switch. Two sets of breather assemblies 114 are located at both ends of the top of the cylindrical tank 112 for discharging gas from the circulation tank.

[0032] The bottom of each of the two hemispheres 113 is provided with a liquid inlet 115, and a spray ball 116 is installed at each liquid inlet 115. The two liquid inlets 115 are connected to a two-way liquid inlet pipeline 117. A first automatic diaphragm valve 118 is installed on a branch of the two-way liquid inlet pipeline 117 to control the liquid inlet channel separately. When the first automatic diaphragm valve 118 on one side fails, the first automatic diaphragm valve 118 on the other side can continue to complete the liquid inlet operation, thereby ensuring the normal operation of the process. The top of each of the two hemispheres 113 is provided with a return liquid inlet, which is connected to a two-in-one return liquid pipeline 115. Similarly, a second automatic diaphragm valve 119 is installed on a branch of the two-in-one return liquid pipeline 115. This redundant design ensures the normal operation of the process.

[0033] This embodiment also redesigns a filter screen 120 to prevent the concentrate at the higher filling nozzle 111 position from being quickly transferred to the lower position due to the tilt when the circulation tank is tilted, so that there is no or very little concentrate flowing out from the higher filling nozzle 111 position.

[0034] The filter screen 120 is assembled at both ends of the cylindrical tank 112. The filter screen 120 and the cylindrical tank 112 are detachably connected, for example, by snap-fit ​​or by internal thread connection with the cylindrical tank 112. The mesh density of the filter screen 120 gradually decreases from the return pipe port to the inlet pipe port 115. The filter screen 120 has an overall arc-shaped structure and is recessed towards the cylindrical tank 112.

[0035] For details, please see Figure 4The filter screen 120 has three pore sizes, defined by circles of 1 / 4 hemisphere 113 radius, 1 / 2 hemisphere 113 radius, and 1 / 3 hemisphere 113 radius. The pore size within the 1 / 4 hemisphere 113 radius circle is the first pore size 121, the pore size within the 1 / 2 hemisphere 113 radius circle is the second pore size 122, and the pore size within the hemisphere 113 radius circle is the third pore size 123, resulting in a filter screen 120 with an increased pore size component. The third pore size = 2 * the second pore size = 4 * the first pore size. The filter screen 120 includes at least one filling nozzle 111, so that when tilted, the flow rate of the concentrate at the higher filling nozzle 111 is slowed down, allowing the concentrate to be discharged from the higher filling nozzle 111.

[0036] Please see Figure 1-3 The filling and storage circulation tank also includes a fishbone positioning frame 130, which is used to improve the stability of the circulation tank and prevent tilting. The fishbone positioning frame 130 has fasteners on the two end platforms 131 to fix the circulation tank body 110. The middle part of the fishbone positioning frame 130 is composed of arc-shaped retaining rings 001 distributed in a fishbone shape. The fishbone positioning frame 130 matches the bottom shape of the circulation tank. The fishbone part in the middle of the fishbone positioning frame 130 is arc-shaped and has a positioning notch 139 for positioning and passing through the double-row filling nozzles 111. The fishbone positioning frame 130 is welded to the frame of the filling equipment.

[0037] Specifically, the fasteners can adjust the level of the circulation tank. They include a shock absorber 132 and an adjusting screw 133. The upper part of the shock absorber 132 is provided with a flange 134 for connecting and fixing the circulation tank. The bottom of the shock absorber 132 is provided with two sets of threaded grooves 135. The corresponding holes of the threaded grooves 135 of the fishbone positioning frame 130 are provided with hollow guide posts 136 with internal threads. The hollow guide posts 136 are inserted into the threaded grooves 135 to provide assembly positioning and also to ensure that the adjusting screw 133 plays a guiding role when lifting the shock absorber 132. The adjusting screw 133 is inserted into the through hole below the guide post of the fishbone positioning frame 130, and a fastening nut 137 is installed on the adjusting screw 133.

[0038] Furthermore, a washer 138 can be provided between the fastening nut 137 and the adjusting screw.

[0039] A level detection sensor or monitor is installed on the body of the circulating tank. When a tilt occurs, the fastening nut 137 is removed, and the adjusting screw 133 is continuously drilled in so that the adjusting screw 133 lifts the vibration damping table 132. After leveling, the fastening nut 137 is tightened, so that the internal thread of the hollow guide post 136 and the fastening nut 137 simultaneously fix the adjusting screw 133 to prevent the adjusting screw 133 from moving.

[0040] In summary, the advantages of the dual-sided liquid inlet and return filling and storage circulation tank in this embodiment are:

[0041] 1. The improved filling and storage circulation tank has changed the original inlet and outlet pipeline and method. The original top inlet has been changed to simultaneous inlet from both ends of the bottom of the circulation tank. When the circulation tank is tilted, the filling nozzle 111 on the side will not have no concentrated liquid output. At the same time, compared with the original single pipeline relying on pressure for liquid return, it has been redesigned to return from the top of both sides of the circulation tank. This means that when the diaphragm valve malfunctions and the return on one side fails, the other side can still continue to operate.

[0042] 2. The filtration device inside the circulating tank has been improved. A concave arc-shaped filter screen 120 is set between the hemisphere 113 and the cylindrical tank 112, so that when liquid is fed in, impurities can be stored in the spherical space formed by the hemisphere 113 and the filter screen 120. At the same time, in case of tilting, the mesh density of the filter screen 120 gradually decreases from the return pipe port to the inlet pipe port 115, so that the filter screen 120 has a certain concentration storage capacity, thereby further avoiding the situation where the filling nozzle 111 on the tilted side has no concentration output.
