Detailed Description of the Embodiment

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment:

[0026] Referring to Figures 1-4 , a steam treatment machine liquid tank liquid level automatic detection and control device disclosed by the present invention includes a water tank 1. The upper end of the water tank 1 is symmetrically and fixedly connected with a condensate pipe inlet connecting pipe 2 and a liquid addition and replenishment pipe 3. The lower part of the side of the water tank 1 is fixedly connected with a liquid outlet pipe 5, and a liquid outlet pump 6 is installed on the other side of the liquid outlet pipe 5;

[0027] A liquid level gauge installation groove 9 is provided on the side wall of the water tank 1, and an electronic liquid level gauge 10 is arranged between the side walls of the liquid level gauge installation groove 9;

[0028] A connecting member is provided on the electronic liquid level gauge 10 and is connected to the liquid level gauge installation groove 9. The connecting member includes a connecting base 11. The upper end of the connecting base 11 is fixedly connected with an installation frame 17 with openings on both sides. The lower end of the electronic liquid level gauge 10 is fixedly connected with a connecting plate 18 with an opening at the lower end.

[0029] A detachable mechanism 16 is provided between the connecting plate 18 and the installation frame 17 for fixing between the connecting plate 18 and the installation frame 17.

[0030] In this embodiment, the condensate inlet connecting pipe 2 is filled with the coolant water for the steam processor. Preferably, a cooling component for the coolant water, such as a condenser, can be provided in the condensate inlet connecting pipe 2. The condensate inlet connecting pipe 2 and the liquid outlet pump 6 are respectively connected to the condensate water outlet pipe and the inlet pipe of the steam engine. After the condensate water outlet pipe enters the water tank 1 from the condensate inlet connecting pipe 2, the electronic liquid level gauge 10 measures the liquid in the water tank 1 multiple times to detect the average water level in the water tank 1. When it is in a state where the water is consumed, the electric valve 4 is opened, and the liquid adding and replenishing pipe 3 is connected to the external water source and water pump. Water is filled into the water tank 1 from the outside through the liquid adding and replenishing pipe 3. A PCL controller is also provided on the outer side of the water tank 1. The electronic liquid level gauge 10, the liquid outlet pump 6, and the electric valve 4 are signal-connected to the PCL controller. The PCL controller, the electronic liquid level gauge 10, the liquid outlet pump 6, and the electric valve 4, etc. are electrically connected to the external power supply. The PCL controller controls the start of the external water pump and the liquid outlet pump 6 by detecting the data of the electronic liquid level gauge 10, realizing the automatic detection, automatic liquid replenishment, and condensate water transportation of the condensate water tank 1. As the electronic liquid level gauge 10 is used for a long time, the sensitivity may become not high and the detection effect may become poor. At this time, the electronic liquid level gauge 10 is driven away from the water tank 1 through the connecting base 11, and the connecting plate 18 and the installation frame 17 are detachably fixed through the detachable mechanism 16. Here, the electronic liquid level gauge 10 and the connecting plate 18 can be adhered together with waterproof glue or fixed together with bolts. Connecting and disassembling the electronic liquid level gauge 10 to the connecting base 11 can drive the electronic liquid level gauge 10 to leave the water tank 1 together, facilitating the replacement or maintenance of the electronic liquid level gauge 10.

[0031] Further, for details, please refer to Figure 2 and Figure 3 An installation part is provided on the electronic liquid level gauge 10. The installation part is a side protection plate 12 fixedly connected to one side of the connecting base 11. The upper end of the side protection plate 12 is fixedly connected with a T-shaped top support 13, and there is an installation gap between the T-shaped top support 13 and the upper end of the electronic liquid level gauge 10.

[0032] In this embodiment, the upper part of the T-shaped top support 13 and the electronic liquid level gauge 10 do not come into contact. When installing the electronic liquid level gauge 10, the electronic liquid level gauge 10 can be attached to the bottom of the T-shaped top support 13. The side protection plate 12 and the connection base 11 not only play a role in installing the electronic liquid level gauge 10 here, but also have a protective function, so that the following L-shaped block 1601 can be located above the upper slot of the installation frame 17.

[0033] Further, specifically, please refer to Figure 4 , the detachable mechanism 16 includes two L-shaped blocks 1601. Both of the two L-shaped blocks 1601 are slidably connected to the inside of the connecting plate 18, and the two side end portions of the two L-shaped blocks 1601 are respectively caught in the two side openings of the installation frame 17. Spring 1603 is fixedly connected between the two side walls of the two L-shaped blocks 1601 and the connecting plate 18.

[0034] In this embodiment, when squeezing the two L-shaped blocks 1601, the spring 1603 is in a compressed state. Insert the L-shaped block 1601 into the installation frame 17. The side wall of the installation frame 17 squeezes the L-shaped block 1601, so that the spring 1603 is always in a compressed state. When the side end of the L-shaped block 1601 reaches the side opening of the installation frame 17, the L-shaped block 1601 is not affected by the acting force of the inner wall of the installation frame 17. Due to its own elasticity, the spring 1603 restores, and pushes the side end of the L-shaped block 1601 to be caught in the slot on the side of the installation frame 17, realizing the detachable fixation of the connecting plate 18 and the installation frame 17.

[0035] Further, specifically, please refer to Figure 4 , the detachable mechanism 16 further includes two sliding rods 1602. Both of the two sliding rods 1602 are fixedly connected between the side walls of the connecting plate 18, and both of the two L-shaped blocks 1601 are slidably connected to the circumferential sides of the two sliding rods 1602.

[0036] In this embodiment, the L-shaped block 1601 is slidably connected to the surface of the sliding rod 1602, which can make the L-shaped block 1601 always move in a straight line and prevent the L-shaped block 1601 from shaking during the movement.

[0037] Further, specifically, please refer to Figure 3 , both sides of the T-shaped top support 13 are fixedly connected with connecting ears 14. Connecting bolts 15 are arranged in both of the two connecting ears 14, and both of the two connecting bolts 15 are threadedly inserted into the upper end of the water tank 1.

[0038] In this embodiment, for the connecting ear 14 and the connecting bolt 15, the connecting bolt 15 is connected to the water tank 1 through the threaded hole opened on the upper side of the water tank 1. The upper end of the connecting bolt 15 can catch the connecting ear 14, which can prevent the connecting ear 14 from moving upward and leaving the water tank 1.

[0039] Further, for specific reference, please refer to Figure 2 , an impact-proof plate 7 is fixedly connected to the inner top wall of the water tank 1, and the impact-proof plate 7 is located directly below the notch of the liquid addition and replenishment pipe 3, and the side of the impact-proof plate 7 is close to the side wall of the water tank 1.

[0040] In this embodiment, the impact-proof plate 7 is similar to an "L" shape. When the liquid addition and replenishment pipe 3 adds liquid, the water falls on the impact-proof plate 7 and flows downward along the gap between the impact-proof plate 7 and the side wall of the water tank 1, which can slow down the flow rate of the water and prevent the electronic liquid level gauge 10 from being damaged by the impact of the water flow.

[0041] Further, for specific reference, please refer to Figure 2 , a plurality of speed bumps 8 are fixedly connected to the upper end of the liquid receiving part of the impact-proof plate 7, and the plurality of speed bumps 8 are evenly distributed on the upper end of the liquid receiving part of the impact-proof plate 7.

[0042] In this embodiment, a liquid receiving part is provided at the lower part of the impact-proof plate 7, and the liquid receiving part is inclined. The speed bumps 8 can reduce the falling speed of the water flow.

[0043] The implementation principle of the above embodiment is as follows: Pull the T-shaped top support 13 outwards. The T-shaped top support 13 drives the electronic liquid level gauge 10 out of the water tank 1 through the connecting base 11 and the side protection plate 12, squeezes the two L-shaped blocks 1601, the two end parts of the L-shaped blocks 1601 contract into the installation frame 17, and the spring 1603 is in a compressed state. Pull the electronic liquid level gauge 10 upwards, and the side wall of the installation frame 17 squeezes the L-shaped blocks 1601, so that the spring 1603 is always in a compressed state until the L-shaped blocks 1601 leave the installation frame 17, realizing the disassembly of the connecting plate 18 and the installation frame 17, and thus realizing the disassembly of the electronic liquid level gauge 10 and the connecting base 11, and maintenance personnel can repair or replace the electronic liquid level gauge 10.

[0044] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0045] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
