Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, and in particular to an air-blowing mixed liquid stirring device for testing. Background Art

[0002] The current development process of many products often involves examining the product's ability to operate in impure liquids, and its ability to resist long-term erosion and wear in the presence of foreign matter. Therefore, tests such as impurity resistance and foreign matter resistance have become necessary items to verify many products in the R&D stage.

[0003] Verifying the impurity resistance test often requires taking multiple product samples for verification. Therefore, a multi-station foreign body resistance test bench has emerged. However, during the test, multiple stations often require multiple tanks to store and circulate the impurity liquid, and there are requirements for heat exchange, temperature sampling, and stirring the impurity liquid. As a result, most tanks are currently equipped with components such as agitators, heaters, and temperature sensors. Such multi-station tanks composed of multiple tanks have problems such as complex overall structure, high energy consumption of running multiple heating and stirring devices, cumbersome operation of multiple test components, and high test maintenance costs. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing stirring device is composed of multiple tank bodies, which has high cost, complex structure, high energy consumption, and is inconvenient to operate. In order to overcome the above defects of the existing technology, the present invention provides a method of integrating multiple tank bodies into one and controlling them in a unified manner, making the structure simpler, reducing costs, and greatly improving the convenience of operation.

[0005] In order to achieve the purpose of this utility model, the following technical solutions are adopted:

[0006] An experimental air-blowing mixed liquid stirring device comprises a tank body and at least two mixing stations, all of which are arranged on the tank body. Each mixing station includes a liquid outlet pipe for discharging liquid out of the tank body, a liquid return pipe for returning liquid to the tank body, and an air blow pipe for blowing mixed air into the tank body. The liquid outlet pipe, liquid return pipe, and air blow pipe are all connected to the inner cavity of the tank body. The liquid outlet pipe in any mixing station is connected to the liquid return pipe in the remaining mixing station via a circulation pump to achieve cross-circulation operation. Each liquid outlet pipe and each liquid return pipe is provided with a flow switch. The device integrates multiple tank bodies into one and uniformly controls them, cross-connecting the liquid outlet pipes and liquid return pipes of multiple stations to achieve a circulating flow and achieve a uniform mixing effect. The cross-connection method of the multiple stations can adopt a variety of algorithms. At the same time, the air blow pipe is combined with air-blowing to disperse and stir instead of the existing motor-driven stirring to achieve a uniform mixing effect. The device has certain innovations, a simpler structure, lower cost and energy consumption, and is easy to operate and maintain.

[0007] Preferably, all the mixing stations are arranged transversely and spaced apart on the tank body, and the return pipe, air blow pipe, and liquid outlet pipe in each mixing station are arranged vertically from top to bottom; all the return pipes are aligned transversely and spaced apart; all the air blow pipes are aligned transversely and spaced apart; and all the liquid outlet pipes are aligned transversely and spaced apart. By arranging the return pipes, air blow pipes, and liquid outlet pipes in this manner, the entire structure becomes neater and cleaner, and the liquid can flow directly out from the bottom and return from the top, further facilitating uniform mixing of the liquids.

[0008] Preferably, when there are three mixing stations, the liquid outlet pipe of the left mixing station is connected to the liquid return pipe of the right mixing station; the liquid outlet pipe of the right mixing station is connected to the liquid return pipe of the left mixing station; and the liquid outlet pipe of the middle mixing station is connected to the liquid return pipe of the middle mixing station.

The liquid outlet funnel facilitates the collection of liquid at the bottom, thereby facilitating the liquid to be discharged from the liquid outlet pipe.

[0010] Preferably, the side of the tank is further provided with a heating connection hole for connecting to a heating device, a temperature sampling connection hole for connecting to a temperature sampling device, and a temperature control connection hole for connecting to a temperature control device. This structure replaces the existing need for separate components for stirring, heating, temperature sampling, and temperature control, and integrates the heating connection holes, temperature sampling connection holes, and temperature control connection holes into a single tank body, meeting cost-effectiveness requirements and also facilitating control and collection.

[0011] Preferably, the top of the tank body is further provided with an air vent and a pressure relief port for connecting to a pressure relief device. By integrating the air vent and the pressure relief port into one tank body, control is facilitated while meeting cost-effectiveness requirements.

[0012] Preferably, the top of the tank body is further provided with a liquid infusion port; a plugging cover is detachably connected to the liquid infusion port, so that the mixed reagent prepared before the test can be conveniently added into the tank body through the liquid infusion port.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 2As shown, an experimental air-blowing mixed liquid stirring device includes a tank body 1 and at least two mixing stations arranged on the tank body 1. All mixing stations are distributed on the tank body 1. Each mixing station includes a liquid outlet pipe 2 for outputting liquid to the outside of the tank body 1, a liquid return pipe 3 for returning liquid to the tank body, and a blowing pipe 4 for mixing and blowing air into the tank body 1. The blowing pipe 4 is connected to the external blowing device and realizes blowing air into the interior through the blowing pipe 4 to promote uniform stirring of the internal liquid. The stirring by blowing replaces the mechanical method of the traditional motor-driven stirrer, which can achieve the requirements of reducing failure rate, improving reliability, facilitating operation and easy maintenance. The liquid outlet pipe 2, the liquid return pipe 3 and the blowing pipe 4 are all connected to the inner cavity of the tank body 1. One liquid outlet pipe 2 corresponds to one liquid return pipe 3. During the connection process, the liquid outlet pipe 2 in any mixing station is connected to the liquid return pipe 3 in the remaining mixing station through a circulation pump to achieve cross-circulation operation. The liquid outlet pipe 2 is connected to a circulation pump, which is then connected to the test product through the circulation pump, and finally connected back to the liquid return pipe 3 to form a circulation loop. The liquid return pipe 3 of multiple stations adopts a cross-circulation operation. At the same time, the cross-connection method of multiple stations can adopt a variety of algorithm forms, and the mixed liquid is blown away by the blowing pipe 4 to achieve uniform stirring. It has certain innovations and meets the requirements of structural simplicity. Each liquid outlet pipe 2 and each liquid return pipe 3 is provided with a flow switch 5. The flow switch 5 can control the opening and closing of each pipe, thereby facilitating better testing of various algorithm forms. The device integrates multiple tanks into one and uniformly controls them, cross-connects the liquid outlet pipes 2 and liquid return pipes 3 of multiple stations, can achieve circulation flow, and achieve the effect of uniform stirring. The cross-connection method of multiple stations can adopt a variety of algorithm forms. At the same time, the blowing pipe 4 uses air-blowing to disperse and stir instead of the existing motor-driven stirring to achieve the effect of uniform stirring. It has certain innovations, a simpler structure, lower cost and energy consumption, and is easy to operate and maintain.

[0023] like Figure 1 and Figure 2As shown, in this embodiment, the device is provided with three mixing stations, which are arranged horizontally and evenly spaced on the tank body 1. The return pipe 3, air blowing pipe 4 and liquid outlet pipe 2 in each mixing station are vertically aligned from top to bottom and arranged at intervals; the three return pipes 3 are horizontally aligned and arranged at intervals; the three air blowing pipes 4 are horizontally aligned and arranged at intervals; and the three liquid outlet pipes 2 are horizontally aligned and arranged at intervals. By arranging the return pipe 3, air blowing pipe 4 and liquid outlet pipe 2 in this manner, the entire structure can be made neater and cleaner, the pipelines are clearer, the connection is convenient, the connection error rate is reduced, and the liquid is conveniently discharged directly from the bottom and returned from the top, further facilitating uniform mixing of the liquids. The connection method of this embodiment is as follows: the liquid outlet pipe 2 of the left mixing station is connected to the return pipe 3 of the right mixing station; the liquid outlet pipe 2 of the right mixing station is connected to the return pipe 3 of the left mixing station; and the liquid outlet pipe 2 of the middle mixing station is connected to the return pipe 3 of the middle mixing station. Through the left-right cross connection mode, the mixed liquid is allowed to circulate crosswise to achieve a uniform stirring effect.

[0024] like Figure 1 and Figure 2 As shown, a liquid outlet funnel 11 is provided at the bottom of the tank body 1 corresponding to each liquid outlet pipe 2; the top of the liquid outlet funnel 11 is connected to the inner cavity of the tank body 1; and the bottom of the liquid outlet funnel 11 is connected to the liquid inlet end of the liquid outlet pipe 2. The liquid outlet funnel 11 can facilitate the collection of liquid at the bottom, thereby facilitating the liquid to be sent out from the liquid outlet pipe 2. The side of the tank body 1 is also provided with a heating connection hole 12 for connecting to a heating device, a temperature connection hole 13 for connecting to a temperature sampling device, and a temperature control connection hole 14 for connecting to a temperature control device. The top of the tank body 1 is also provided with an air vent 15 and a pressure relief port 16 for connecting to a pressure relief device. The pressure relief device is a safety valve and a regulating valve. The air vent 15 is connected to the safety valve, and the pressure relief port 16 is connected to the regulating valve. The regulating valve can adjust the internal pressure according to the test needs and release the internal pressure after the test, so as to better control the internal pressure and facilitate the test. The above structure changes the existing multiple test stations that rely on the rotating mechanical stirring of each station and need to be equipped with stirring, heating, temperature sampling, temperature control and other components separately. The present embodiment integrates multiple tank bodies of multiple stations into one, making the entire structure simpler and more convenient to operate, and uniformly arranges components such as heating, temperature sampling, temperature control, exhaust, and pressure relief on an integral tank body, meeting the needs of cost economy, and also facilitating control and test collection. A fluid infusion port is also provided on the top of the tank body 1; a plugging cover 6 is detachably connected to the fluid infusion port, and the plugging cover 6 is detachable by means of a threaded connection or a snap-on connection. The fluid infusion port allows for the convenient addition of mixed reagents prepared before the test into the tank body 1, and the required reagents can also be added during the experiment, further facilitating the addition of reagents.

[0025] When there are more than three mixing stations on the device, various algorithms can be used according to actual test requirements. For example, when there are four mixing stations, the liquid outlet pipe 2 of the leftmost mixing station is connected to the liquid return pipe 3 of the rightmost mixing station; the liquid outlet pipe 2 of the middle left mixing station is connected to the liquid return pipe 3 of the middle right mixing station; the liquid outlet pipe 2 of the middle right mixing station is connected to the liquid return pipe 3 of the middle left mixing station; and the liquid outlet pipe 2 of the rightmost mixing station is connected to the liquid return pipe 3 of the leftmost mixing station. Through cross-connection, various algorithms can be used to achieve the effect of uniform mixing of mixed reagents according to the parameter requirements of different impurity tests.

[0026] In summary, the advantage of the present invention is that the device adopts an integrated one-piece tank body 1, which avoids multiple stations and multiple tank bodies, resulting in complex structure, large floor space, poor reliability, and improves economy. It reduces the overall processing difficulty in production, while extending the life of the test box and increasing its reuse capacity. It also adopts a multi-station air-blowing method to disperse the mixed liquid for stirring, which reduces energy consumption, has a simple structure, and is convenient for maintenance compared to motor-driven stirring. At the same time, the cross-connection method of multiple stations can adopt a variety of algorithm forms. According to the parameter requirements of different impurity tests, it can adjust whether to heat, collect temperature, control temperature, and whether to blow air for stirring. It can be applied to a variety of multi-station stirring cycle modes, and the cross-type liquid return stirring method is used alone for testing, which meets the needs of multiple parameters and a wide range of applicable conditions. The overall device has a certain degree of innovation and achieves the effect of uniform stirring. It has a simpler structure, lower cost and energy consumption, and is easy to operate and maintain.
