DETAILED DESCRIPTION

[0028] The following will be described in detail in combination with the accompanying Figures 1-3 The present application will be further described in detail.

[0029] The embodiment of the present application discloses a distilled water preparation equipment. Referring to Figure 1 , Figure 2 and Figure 3The system includes a heater 1, a condenser 2, and a water storage tank 3, which are connected by a transmission pipe 4. An abutment plate 5 is provided on the inner wall of the transmission pipe 4, and a filter screen 6 is provided on the abutment plate 5. An installation plate 10 is provided around the filter screen 6, and the installation plate 10 is placed on the surface of the abutment plate 5. Replacement notches 7 are provided on the transmission pipe 4 between the heater 1 and the condenser 2, and between the condenser 2 and the water storage tank 3. Each replacement notch 7 is semi-circular and located above the filter screen 6. A closing ring 8 is provided within each replacement notch 7. The closing ring 8 is semi-circular and its shape matches the replacement notch 7. Arc-shaped pieces 16 are provided at both ends of the closing ring 8. The arc-shaped pieces 16 are made of elastic material and are fitted to the outer wall of the transmission pipe 4. Fasteners 17 are provided on the arc-shaped pieces 16. In this embodiment, the fasteners 17 are bolts, used to fix the closing ring 8 to the transmission pipe 4.

[0030] Reference Figure 1 and Figure 2 The surface of the abutment plate 5 is formed with several guide posts 9. The bottom wall of the mounting plate 10 is provided with several guide holes 11 for the guide posts 9 to be inserted. The periphery of the guide posts 9 is fitted with a return spring 12, which abuts against the mounting plate 10 and the abutment plate 5. The inner wall of the sealing ring 8 is formed with a stabilizing block 13, which abuts against the top wall of the mounting plate 10. The side of the stabilizing block 13 away from the sealing ring 8 is provided with a guide surface 14 to prevent liquid from accumulating on the stabilizing block 13. When the sealing ring 8 is installed and fixed, the return spring 12 is in a compressed state. When the sealing ring 8 is removed, the return spring 12 releases its elastic potential energy, thereby lifting the mounting plate 10 upward. The periphery of the mounting plate 10 is provided with a pick-up and put-down notch 15 for easy picking up of the mounting plate 10. Each transmission pipe 4 is provided with an on / off valve 18, so that when the filter screen 6 is replaced, the transmission pipe 4 can be closed by the on / off valve 18 to prevent distilled water leakage.

[0031] Reference Figure 1 and Figure 2 A transfer container 19 is provided between the condenser 2 and the water storage tank 3. The transfer container 19 is connected to a discharge pipe 20. Solenoid valves 21 are provided at the connection points between the transfer container 19, the discharge pipe 20, and the water storage tank 3. A water quality analyzer 22 is provided inside the transfer container 19. The water quality analyzer 22 is communicatively connected to a control module 23. In this embodiment, the control module 23 is a PLC controller. The solenoid valves 21 are all controlled by the control module 23. The control module 23 controls the opening and closing of the corresponding solenoid valves 21 based on the detection results of the water quality analyzer 22. If the detection result is qualified, the solenoid valve 21 on the water storage tank 3 is opened and the solenoid valve 21 on the discharge pipe 20 is closed. Conversely, the solenoid valve 21 on the water storage tank 3 is closed and the solenoid valve 21 on the discharge pipe 20 is opened. At the same time, the staff can also determine whether the filter screen 6 needs to be replaced based on the opening and closing status of the two solenoid valves 21.

[0032] The implementation principle of the distilled water preparation device in this application embodiment is as follows: When the filter screen 6 needs to be replaced, the closing ring 8 only needs to be removed from the transmission pipe 4. Without the contact of the stabilizing block 13, the return spring 12 releases its elastic potential energy, which lifts the mounting plate 10 and the filter screen 6 upwards, so that the filter screen 6 can be taken out from the replacement notch 7. Since the replacement notch 7 is opened in a semi-circular shape, it will not interfere with the filter screen 6 when it is replaced, which improves the convenience of replacing the filter screen 6 and avoids the system blockage problem caused by the inconvenience of replacing the filter screen 6 after long-term use. This improves the purity of distilled water and production efficiency.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
