Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of gas movement form recording equipment in liquid, especially relates to a water model experiment device. BACKGROUND

[0002] Water model refers to using water for numerical simulation and simulation test. In many fluid calculations such as steelmaking, due to the need of engineering simulation, other liquids are used for prior simulation when establishing a model to observe flow field and some other parameters. This can be used as a contactable test for further research.

[0003] At present, water model is needed in many fields to verify the reliability of simulation results of some corresponding data. For example, biomass energy has the advantages of low sulfur, zero emission of carbon dioxide and large storage capacity, and is a renewable and environment-friendly energy source. Biomass pyrolysis technology can effectively convert low utilization rate biomass into high energy liquid fuel, i.e. biomass fast pyrolysis oil, also known as bio-oil. Biomass pyrolysis is a very complex physical and chemical reaction process, which is the result of interaction of more than 300 intermediate products. Numerical simulation of pyrolysis process by computational fluid dynamics (CFD) can help us reveal the causes of complex physical phenomena in the reactor, describe the ability of complex flow in the reactor, and through calculation of detailed characteristic parameters in the reactor, data post-processing can clearly show the state of flow, heat transfer and pyrolysis reaction in the reactor. In order to verify the reliability of the above simulation results, water model is needed for verification.

[0004] However, most of the current water models are single bubble generating devices located in the box, and liquid is added in the box for data simulation. However, some experiments need to adjust the size of the gas bubbles formed in water to

[0005] Different size bubbles are monitored and recorded for subsequent research and simulation verification. In traditional water model test equipment, different size gas inlets need to be frequently replaced to complete the test, and replacing different size gas inlets is time-consuming and laborious.

[0006] In order to solve the above problems, we provide a water model experiment device which can adjust the size of the gas inlet at any time and can complete the water model test. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to overcome the deficiencies in the prior art and provides a water model experiment device.

[0008] The purpose of this utility model is achieved as follows: a water model experimental device includes a generating mechanism, which includes a box, an air inlet at the lower end of the box, and a detection mechanism on the side of the box. Water is placed inside the box, and gas is supplied into the box through the air inlet. The gas forms bubbles through the air inlet, and the detection mechanism records the movement pattern of the bubbles in the water.

[0009] Furthermore, the testing mechanism includes a speed measuring instrument and a terminal. The speed measuring instrument monitors the movement pattern of the bubbles inside the chamber and transmits the monitored signals to the terminal for recording and analysis. The speed measuring instrument and the terminal are existing technologies and will not be described in detail. Other methods can also be used to monitor and record the movement pattern of the bubbles.

[0010] Furthermore, the lower end of the air inlet is connected to an air inlet pipe, the upper end of which is located on the upper outer side of the housing. The upper end of the air inlet pipe is connected to a hose, and the outer end of the hose is connected to an air supply mechanism.

[0011] Furthermore, the hose is equipped with a flow meter and a valve. The flow meter is a flow meter that can control the gas flow rate, which is existing technology and can achieve the above functions, so no further technical details are required. The valve can control whether the gas enters the inlet pipe at the rear end.

[0012] Furthermore, the housing is equipped with a turntable that can rotate around a shaft diameter, and multiple exhaust ports of different sizes are evenly distributed in a ring on the turntable.

[0013] Furthermore, a placement compartment is provided at the bottom, and a motor is installed inside the placement compartment. The output end of the motor drives the turntable to rotate.

[0014] In use, liquid (such as water) is added to the chamber, and gas is supplied to the hose through the gas supply mechanism. The valve is opened, and the gas enters the inlet pipe through the hose. The flow rate of the gas is controlled by a flow meter. The gas enters the chamber through the inlet pipe and generates bubbles. The movement pattern of the bubbles is detected and recorded by a detection mechanism. Since the size of the bubbles generated by different exhaust ports is also different, when it is necessary to monitor the movement pattern of different bubble sizes, the position of the exhaust ports of different sizes on the turntable above the inlet can be adjusted by controlling the rotation of the motor, thereby changing the size of the bubbles passing through the exhaust ports.

[0015] When the turntable rotates, because there is a spring under the lifting block, the upward force of the spring can keep the upper surface of the lifting block in contact with the lower surface of the turntable, thus preventing gaps between the lifting block and the turntable and causing gas to escape from between them; the rotation angle of the motor can be precisely controlled, which is existing technology and will not be described in detail.

[0016] Furthermore, a heating mechanism is installed at the bottom of the chamber to achieve precise temperature control of the water inside the chamber, thereby enabling the monitoring of the movement pattern of bubbles in liquids at different temperatures.

[0017] Beneficial effects: This device can monitor air bubbles and adjust the size of the exhaust port in the water as needed. During the adjustment of the exhaust port, a lifting block that can move up and down can prevent gaps between the lifting block and the turntable, which would cause gas to overflow from between them. The upper end of the air inlet pipe is located at the top of the chamber, which can prevent water in the chamber from overflowing into the hose through the upper end of the air inlet pipe.

[0025] Example 1, as shown in Figures 1-5, achieves the purpose of this utility model as follows: A water model experimental device includes a generating mechanism 4, which includes a housing 401. An air inlet is provided at the lower end of the housing 401, and a detection mechanism is provided on the side of the housing 401. Water is placed inside the housing 401, and gas is supplied into the housing 401 through the air inlet. The gas forms bubbles through the air inlet, and the detection mechanism records the movement pattern of the bubbles in the water.

[0026] The detection mechanism includes a speed measuring instrument 3 and a terminal 7. The speed measuring instrument 3 monitors the movement pattern of the bubbles in the box 401 and transmits the monitored signals to the terminal 7 for recording and analysis. The speed measuring instrument 3 and the terminal 7 are existing technologies and will not be described in detail. Other methods can also be used to monitor and record the movement pattern of the bubbles.

[0027] An air inlet pipe 403 is connected to the lower end of the air inlet. The upper end of the air inlet pipe 403 is located on the upper outer side of the housing 401. The upper end of the air inlet pipe 403 is connected to the hose 5. The outer end of the hose 5 is connected to the air supply mechanism 6. The air supply mechanism 6 is existing technology and will not be described in detail.

[0028] The hose 5 is equipped with a flow meter 1 and a valve 2. The flow meter 1 is a flow meter that can control the gas flow rate. It is existing technology and can achieve the above functions. No further technical details are required. The valve 2 can control whether the gas enters the inlet pipe 403 at the rear end.

[0029] The housing 401 contains a turntable 404 that can rotate around a shaft diameter. Multiple rings are evenly distributed on the turntable 404.

[0030] There are several exhaust ports of different sizes. A storage compartment is located at the bottom, containing a motor 405. The output of motor 405 drives a turntable 404 to rotate. A lifting groove is provided at the upper end of the air inlet, within which a lifting block 409 is movable vertically. A through hole is provided in the middle of lifting block 409. A telescopic tube 408 is fixedly installed at the lower end of lifting block 409, and a spring 407 is installed on the outer side of the lower end of lifting block 409, with the lower end of spring 407 connected to the bottom of the lifting groove. A heating mechanism 406 is located at the bottom of the housing 401, heating the water inside the housing 401.

[0031] In use, liquid (such as water) is added to the housing 401, and gas is supplied to the hose 5 through the gas supply mechanism 6. The valve 2 is opened, and the gas enters the air inlet pipe 403 through the hose 5. The flow rate of the gas is controlled by the flow meter 1. The gas enters the housing 401 through the air inlet pipe 403 and generates bubbles. The movement pattern of the bubbles is detected and recorded by the detection mechanism. Since the size of the bubbles generated by different exhaust ports is also different, when it is necessary to monitor the movement pattern of different bubble sizes, the rotation of the motor 405 can be controlled to adjust the position of the exhaust ports of different sizes on the turntable 404 above the air inlet, thereby changing the size of the bubbles passing through the exhaust ports.

[0032] When the turntable 404 is rotated, because a spring 407 is installed below the lifting block 409, the upward elastic force of the spring 407 can keep the upper surface of the lifting block 409 in contact with the lower surface of the turntable 404, thus preventing gaps between the lifting block 409 and the turntable 404 and causing gas to leak out. The rotation angle of the motor 405 can be precisely controlled, which is existing technology and will not be described in detail.

[0033] Furthermore, a heating mechanism 406 is provided at the bottom of the chamber 401, which can achieve precise temperature control of the water inside the chamber 401, thereby enabling the monitoring of the movement pattern of bubbles in liquids at different temperatures.
