A storage tank in which liquids can flow and mix.

Abstract

This utility model provides a storage tank for internal liquid flow and mixing, including a tank body. The bottom of the tank body's inner cavity has multiple suction ports, and the inner wall of the tank body has a discharge port. A liquid delivery pipeline is provided between the suction ports and the discharge port, connecting all the suction ports and the discharge port. A liquid delivery pump is installed on the liquid delivery pipeline. The pump causes the liquid stored in the tank cavity to flow from the suction ports into the discharge ports and then out, thereby causing the liquid stored in the tank cavity to flow and mix. This proposed storage tank for internal liquid flow and mixing effectively addresses material stratification and deterioration of the material at the bottom of the tank. By using a liquid delivery pipeline between the suction ports and the discharge ports, the liquid stored in the tank cavity flows from the suction ports into the discharge ports, allowing the material at the bottom of the tank to flow back into the tank through the liquid delivery pipeline, creating liquid flow and mixing of the materials.

Description

Technical Field

[0001] This utility model belongs to the field of storage tank technology, and in particular relates to a storage tank in which liquids can flow and mix. Background Technology

[0002] The liquid caprolactam tank uses a top inlet for material inlet, with the feed pipe extending 200mm into the tank bottom and the discharge pipe 290mm from the tank bottom. The close proximity of the discharge pipe to the feed inlet results in poor circulation and mixing, causing the liquid caprolactam in the tank to easily form material stratification. The material at the bottom of the tank forms a blind zone that does not circulate for a long time, leading to material deterioration.

[0003] Existing technical solutions to address the issues of material stratification and deterioration of the bottom material in liquid caprolactam include:

[0004] Mechanical stirring: The liquid is made to flow and mix by rotating an electric motor-driven stirrer (such as a paddle or turbine).

[0005] Gas injection mixing: Liquid is drawn from the storage tank and re-injected through an external circulation pump to form a circulating flow and achieve the purpose of mixing.

[0006] Static mixer: A static mixer is installed inside the storage tank or on the outlet pipeline. The liquid is divided and recombined as it passes through, thus achieving mixing.

[0007] Ultrasonic mixing: Utilizing the cavitation effect generated by ultrasound in liquids to create microflows and mixing.

[0008] However, mechanical stirring has disadvantages: complex equipment, high energy consumption, and high maintenance costs; gas jet mixing: weak mixing effect, not suitable for high viscosity liquids; static mixers: only suitable for continuous flow systems, not suitable for static storage tanks; ultrasonic mixing: high equipment cost, suitable for small capacity storage tanks. Utility Model Content

[0009] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model embodiment is to provide a storage tank in which liquid can flow and mix.

[0010] The technical solution adopted in this embodiment of the utility model is a storage tank in which liquid can flow and mix, including a tank body. The bottom of the inner cavity of the tank body is constructed with multiple suction ports, and the inner wall of the tank body is constructed with a discharge port. A liquid delivery pipeline is provided between the suction ports and the discharge port. The liquid delivery pipeline connects all the suction ports and the discharge port, and a liquid delivery pump is installed on the liquid delivery pipeline. The liquid delivery pump causes the liquid stored in the inner cavity of the tank to enter from the suction ports and be discharged from the discharge ports, so as to make the liquid stored in the inner cavity of the tank flow and mix.

[0011] Furthermore, a suction pipe is provided at the bottom of the inner cavity of the tank, and the suction pipe is connected to the infusion pipeline, with the suction port constructed on the suction pipe.

[0012] Furthermore, the suction tube is provided with multiple branch tubes, both of which are parallel to the bottom surface of the inner cavity of the can, and the branch tubes are connected to the suction tube. The opening of the branch tube away from the suction tube forms the suction port.

[0013] Furthermore, multiple branch tubes are respectively arranged on both sides of the suction tube, and the lengths of the multiple branch tubes are not equal.

[0014] Furthermore, the discharge port is an ejector, which is connected to the infusion pipeline.

[0015] Furthermore, the injector includes a connecting pipe that is fixed through the tank wall of the tank body. One end of the connecting pipe located outside the tank body is connected to the infusion pipeline, and the other end of the connecting pipe located inside the tank body is connected to an elbow pipe. The end of the elbow pipe away from the connecting pipe is connected to a nozzle, and the elbow pipe is bent upward so that the nozzle is tilted upward.

[0016] Furthermore, the connecting pipe is circumferentially fixedly connected with several stiffening plates, which are also fixedly connected to the inner wall of the tank.

[0017] Compared with existing technologies, the liquid flowable mixing tank proposed in this technical solution can effectively deal with the situation of material stratification and deterioration of material at the bottom of the tank. By setting up a liquid delivery pipeline between the inlet and outlet, the liquid stored in the inner cavity of the tank enters from the inlet and exits from the outlet, so that the material at the bottom of the tank flows back into the tank through the liquid delivery pipeline to form liquid flow and mix the materials.

[0018] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit the present invention.

[0025] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0026] See Figures 1 to 2 This utility model provides a storage tank for mixing liquids within the tank, comprising a tank body 1. The bottom of the inner cavity of the tank body 1 has multiple suction ports, and the inner wall of the tank body 1 has a discharge port. A liquid delivery pipeline is provided between the suction ports and the discharge port, connecting all the suction ports and the discharge port. A liquid delivery pump is installed on the liquid delivery pipeline. The liquid delivery pump causes the liquid stored in the inner cavity of the tank body 1 to flow from the suction ports into the discharge ports and then discharge, thereby mixing the liquids within the inner cavity of the tank body 1. This technical solution can effectively address the issues of material stratification and deterioration of the material at the bottom of the tank. By providing a liquid delivery pipeline between the suction ports and the discharge ports, the liquid stored in the inner cavity of the tank flows from the suction ports into the discharge ports, allowing the material at the bottom of the tank to flow back into the tank through the liquid delivery pipeline, thus creating liquid flow and mixing the materials.

[0027] In some embodiments, a suction pipe 2 is provided at the bottom of the inner cavity of the tank 1 and is connected to the infusion pipeline. The suction port is constructed on the suction pipe 2 and extends to the bottom of the inner cavity of the tank 1. This can extend the distance between the suction port and the discharge port and allow the suction port to draw in liquid from the bottom of the inner cavity of the tank 1, which helps to form a liquid flow in the inner cavity of the tank 1 and mix the materials.

[0028] In some embodiments, the suction pipe 2 is provided with multiple branch pipes 3. Both the suction pipe 2 and the branch pipes 3 are arranged parallel to the bottom surface of the inner cavity of the tank 1, and the branch pipes 3 are connected to the suction pipe 2. The opening of the branch pipe 3 away from the suction pipe 2 forms a suction port. Multiple branch pipes 3 can extend to different positions at the bottom of the inner cavity of the tank 1 to draw in materials, reducing the material flow blind zone at the bottom of the inner cavity of the tank 1. Furthermore, having multiple suction ports helps to prevent material deterioration caused by long-term non-circulation of materials in the bottom of the tank. Multiple branch pipes 3 increase the circulation of materials at the bottom of the storage tank, contributing to the long-term stable storage of the product quality within the tank 1.

[0029] In some embodiments, a plurality of branch pipes 3 are respectively disposed on both sides of the suction pipe 2, and the lengths of the plurality of branch pipes 3 are unequal. This helps the branch pipes 3 to extend to different positions at the bottom of the inner cavity of the tank 1 to draw in materials, thereby reducing the blind zone of material flow at the bottom of the inner cavity of the tank 1.

[0030] In some embodiments, the discharge port is an ejector 4, which is connected to a liquid delivery pipeline. The ejector 4 sprays material to form a material jet inside the tank 1, which can enhance the material flow inside the tank 1 and help improve the material mixing effect.

[0031] In some embodiments, the injector 4 includes a connecting pipe 41, which is fixed through the tank wall of the tank body 1. One end of the connecting pipe 41 located outside the tank body 1 is connected to a delivery pipeline, and the other end of the connecting pipe 41 located inside the tank body 1 is connected to an elbow pipe 42. The end of the elbow pipe 42, away from the connecting pipe 41, is connected to a nozzle 43. The elbow pipe 42 is bent upwards, causing the nozzle 43 to be angled upwards. This upward-angled nozzle 43 ejects an upward-angled jet, which enhances the flow of material within the tank body 1 and helps improve the mixing effect.

[0032] In some embodiments, a plurality of stiffening plates 44 are fixedly connected circumferentially to the connecting pipe 41, and the stiffening plates 44 are also fixedly connected to the inner wall of the tank body 1. The stiffening plates 44 are used to strengthen the connection between the connecting pipe 41 and the inner wall of the tank body 1.

[0033] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
