Currently, testing the fluidization velocity of molecular sieves is a key step in evaluating their performance.

[0003] At present, the common molecular sieve fluidization velocity test method mainly relies on the traditional fluidized bed device, and the fluidization velocity is calculated by measuring the pressure drop and flow rate in the fluidized bed. However, this method is easily affected by environmental factors such as temperature and pressure, resulting in unstable test results. Utility Model Content

[0015] The outer wall of the cross section of the sliding frame is of a T-shaped structure, and a filter screen is fixedly connected to the inner wall of the sliding frame.

[0016] With the above mechanism, through the setting of the sliding frame, it is convenient to install the filter screen. The filter screen directly filters the vapor, and the slidably connected sliding frame facilitates its disassembly.

[0017] An exhaust port is provided on the outer wall of the top of the filter box, and an exhaust head is fixedly connected to the inner wall of the exhaust port.

A control panel is fixedly connected to the outer wall of the box body, and the control panel is electrically connected to the heating wire and the flow velocity sensor.

[0020] With the above mechanism, through the setting of the control panel, it is convenient to control the heating wire and the flow velocity sensor.

[0021] In summary, the beneficial effects of the present application are as follows:

Detailed implementation manners

[0031] The following will further elaborate on this application in conjunction with Figure 1-6 For a more detailed description of this application.

[0032] Please refer to Figure 1-3 , a boiling device for testing the fluidization velocity of molecular sieves, comprising a box body 1, a filtering component 4 installed on the top of the box body 1, and a boiling mechanism 7 installed inside the box body 1. The boiling mechanism 7 includes a support base 8 fixedly connected to the inner wall of the box body 1, and a heating base 9 is fixedly connected to the outer wall of the top of the support base 8. A heating bottle 10 is arranged on the outer wall of the top of the heating base 9, a clamping joint 11 is clamped on the outer wall of the top of the heating bottle 10, a flow rate sensor 6 communicated with the filtering component 4 is installed on the inner wall of the top of the box body 1, and the flow rate sensor 6 and the clamping joint 11 are connected by the same connecting pipe 12.

[0033] During use, the setting of the box body 1 facilitates the protection of the boiling mechanism 7. The heating base 9 in the boiling mechanism 7 facilitates the installation of the heating bottle 10. The setting of the heating bottle 10 facilitates the holding of the liquid to be tested. The cooperation between the clamping joint 11 on the heating bottle 10 and the connecting pipe 12 facilitates the detection of the gas flow rate in cooperation with the flow rate sensor 6.

[0034] Refer to Figure 5, a circular groove 13 is formed on the outer wall of the top of the heating base 9, and a heating wire 14 with a spiral structure is fixedly connected to the inner wall of the circular groove 13. The circular groove 13 facilitates the fixed installation of the heating wire 14, and the heating wire 14 facilitates heating the liquid in the heating bottle 10 to boiling.

[0035] Refer to Figure 5 , the inner diameter of the heating wire 14 is larger than the outer diameter of the heating bottle 10. By setting the inner diameter of the heating wire 14 to be larger than the outer diameter of the heating bottle 10, it is avoided that the heating bottle 10 directly contacts the heating wire 14, thereby avoiding damage to the outer wall of the heating bottle 10.

[0036] Refer to Figure 1 , an observation port is formed on the outer wall of one side of the box body 1, and an observation window 2 is fixedly connected to the inner wall of the observation port. Through the design of the observation window 2, the fluidization state of the molecular sieve can be directly observed, improving the convenience and operability of the experiment.

[0037] Refer to Figure 6 , the filtering assembly 4 includes a filtering box 15 fixedly connected to the outer wall of the top of the box body 1, and an opening is formed on the outer wall of one side of the filtering box 15. A sliding frame 17 is slidably connected to the inner wall of the opening. The filtering box 15 facilitates filtering the steam entering it.

[0038] Refer to Figure 6 , the cross-section outer wall of the sliding frame 17 is of a T-shaped structure, and a filter screen 18 is fixedly connected to the inner wall of the sliding frame 17. The sliding frame 17 facilitates the installation of the filter screen 18, and the filter screen 18 directly filters the steam, and the slidably connected sliding frame 17 facilitates its disassembly.

[0039] Refer to Figure 6 , an exhaust port is formed on the outer wall of the top of the filtering box 15, and an exhaust head 16 is fixedly connected to the inner wall of the exhaust port. The exhaust head 16 facilitates the installation of other drainage gas pipes.

[0040] Refer to Figure 4 , the flow rate sensor 6 is communicated with the filtering box 15. A box door 5 is hinged to the outer wall of one side of the box body 1, and a control panel 3 is fixedly connected to the outer wall of the box body 1. The control panel 3 is electrically connected to the heating wire 14 and the flow rate sensor 6. The control panel 3 facilitates the control of the heating wire 14 and the flow rate sensor 6.

[0041] The implementation principle of this application is as follows: When in use, first insert the heating bottle 10 filled with the sample into the circular groove 13 on the heating base 9, and then sleeve the clamping connector 11 on the heating bottle 10. When the heating wire 14 is started, it directly heats the liquid in the heating bottle 10 to boiling. After the liquid boils, the vapor directly enters the flow velocity sensor 6 through the connecting pipe 12. The setting of the flow velocity sensor 6 facilitates the real-time monitoring of the gas flow velocity. The gas enters the filtering assembly 4 through the flow velocity sensor 6. The filter screen 18 in the filtering assembly 4 facilitates filtering out impurities in the gas. At the same time, when it is necessary to clean the filter screen 18 later, directly pull out the sliding frame 17 from the filter box 15, so as to facilitate a comprehensive cleaning of the filter screen 18. The setting of the control panel 3 facilitates the real-time monitoring of the electrical components in the boiling device.
