[0026] The following are specific embodiments of the present utility model and in combination with the attached drawings, the technical solutions of the present utility model are further described.

[0027] As Figures 1-5 shown, a vertical deaerator water level detection device includes:

[0028] A water storage tank 1, on which there is a liquid level detection port 11;

[0029] A detection unit 2, the detection unit 2 is arranged at the liquid level detection port 11, and the detection unit 2 includes a thrust rod 26, a liquid level rod 28, a support member 21 and a guide bracket 25 arranged on the support member 21. The guide bracket 25 is provided with chutes 251 arranged in a circumferential array, and the liquid level rod 28 is slidably connected to the support member 21;

[0030] One end of the thrust rod 26 is provided with a floating plate sliding in the chute 251, and the other end thereof is matched with the liquid level rod 28, and a suspension ring 262 is arranged on the floating plate.

[0031] Specifically, a deaerator head 3 is arranged on the water storage tank 1, and oxygen and other gases in the water are taken out through the deaerator head 3, so that the deaerated water flows down into the water storage tank 1. When the water level reaches a certain height, the suspension ring 262 will float and push the thrust rod 26 to slide on the guide bracket 25 until it contacts the liquid level rod 28, and push the liquid level rod 28 to slide towards the liquid level detection port 11 until it slides out of the liquid level detection port 11. By observing the scale line 281 on the liquid level rod 28, the liquid level height in the water storage tank 1 can be obtained.

[0032] As a further embodiment provided by the present utility model, a control switch 4 is provided on the support member 21, and a contact block 286 cooperating with the control switch 4 is provided at one end of the liquid level rod 28. When the adjusting rod 285 makes the bottom plate 287 approach the ejector rod 26, the ejector rod 26 will be quickly in contact with the liquid level rod 28 under the pushing of the floating ring 262. When sliding a certain distance, the contact block 286 of the liquid level rod 28 will trigger the control switch 4, so as to remind of an alarm and stop the deaeration operation. However, the water in the water storage tank 1 does not reach the original liquid level height, and the alarm starts below the original liquid level height. When the adjusting rod 285 makes the bottom plate 287 away from the ejector rod 26, at this time, the distance between the bottom plate 287 and the ejector rod 26 becomes larger, and the longer the time for the ejector rod 26 to contact the bottom plate 287 by the floating ring 262, and the relative liquid level height is also higher than the original liquid level height. The above-mentioned liquid level height refers to the maximum liquid level height of the water storage tank 1. Existing equipment that needs deaeration often connects multiple deaerators, and the water levels of the deaerators can be controlled at a certain height through this device, reducing the phenomenon of unbalanced flow of multiple deaerators.

[0033] As a further embodiment provided by the present utility model, an adjusting rod 285 is threadedly connected to the liquid level rod 28. One end of the adjusting rod 285 is provided with a bottom plate 287 cooperating with the ejector rod 26, and a pull ring 284 is provided at the other end thereof. A pull rope 283 is provided on the pull ring 284; further, scale lines 281 are provided on the liquid level rod 28, and a scale rod 282 engaging with the bottom plate 287 is rotatably connected to the adjusting rod 285. The liquid level rod 28 can be pulled out from the liquid level detection port 11 through the pull rope 283, and then the height of the bottom plate 287 located inside the liquid level rod 28 can be adjusted by rotating the adjusting rod 285, that is, making the bottom plate 287 approach or away from the ejector rod 26.

[0034] As a further embodiment provided by the present utility model, the support member 21 includes a guide sleeve 213, a connecting sleeve 212, and a fixed disk 211 fixed to the liquid level detection port 11. One end of the connecting sleeve 212 is provided with a support portion 2121 engaging with the fixed disk 211, and the other end thereof is threadedly connected to the guide sleeve 213. Reinforcing ribs 241 are provided on the guide sleeve 213 to improve the overall stability. The guide sleeve 213 is pre-placed in the water storage tank 1, the connecting sleeve 212 is clamped to the fixed disk 211, and the connecting sleeve 212 is threadedly connected to the guide sleeve 213 by rotating the fixed disk 211. After continuously rotating for a period of time, the arc portion 2131 on the guide sleeve 213 fits with the inner wall of the water storage tank 1, and the support member 21 is fixed to the inner wall of the water storage tank 1.

[0035] As a further embodiment provided by the present utility model, an arc portion 2131 is provided on the guide sleeve 213. The arc portion 2131 is made of heat-resistant rubber material, so that the arc portion 2131 is completely attached to the inner wall of the water storage tank 1, improving the attachment effect between the guide sleeve 213 and the water storage tank 1.

[0036] As a further embodiment provided by the present utility model, clamping blocks 252 are arranged on the guide bracket 25 in a circumferential array. A spring 253 is arranged between the clamping blocks 252 and the guide. The spring 253 pushes the clamping blocks 252 to engage with the support member 21. By using the pushing effect of the spring 253, the clamping blocks 252 are pushed into the grooves of the guide sleeve 213, fixing the guide bracket 25 to the guide sleeve 213, and at least four clamping blocks 252 are provided.

[0037] As a further embodiment provided by the present utility model, a tapered clamping block 27 is arranged on the guide bracket 25. A temperature-measuring thimble 271 is arranged on the tapered clamping block 27. A water outlet groove 272 is formed on the tapered clamping block 27. The temperature inside the water storage tank 1 is detected by the temperature-measuring thimble 271 to prevent the phenomenon of excessive temperature inside the water storage tank 1.

[0038] As a further embodiment provided by the present utility model, rolling balls 263 in contact with the liquid level rod 28 are arranged on the ejector rod 26. At least two groups of rolling balls 263 are arranged on the ejector rod 26, improving the sliding effect between the ejector rod 26 and the liquid level rod 28 through the rolling balls 263.

[0039] Working principle: The connecting sleeve 212 is clamped to the fixed disk 211, the guide sleeve 213 is placed inside the water storage tank 1, and the arc portion 2131 is attached to the inner wall of the water storage tank 1. Then the fixed disk 211 is rotated to connect the threaded portion of the connecting sleeve 212 with the guide sleeve 213, fixing the guide sleeve 213 to the water storage tank 1. Then the fixed disk 211 is fixed to the liquid level detection port 11 by bolts, improving the installation efficiency. The guide bracket 25 is pre-clamped to the guide sleeve 213 through the clamping blocks 252. The guide bracket 25 is used to limit and support the floating plate 261 and the ejector rod 26. When the liquid level in the water storage tank 1 rises, the floating plate 261 slides upward along the guide bracket 25 axially through the floating ring 262, so that the ejector rod 26 pushes the liquid level rod 28 out of the liquid level detection port 11, exposing the scale line 281, facilitating the observation of the liquid level height inside the water storage tank 1. At the same time, the guide bracket 25 and the support member 21 play a role in guiding and supporting the liquid level rod 28, reducing the influence of bubbles on the liquid level detection and improving the detection accuracy.

[0040] The above technical solution of the present utility model provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single. For the parts not involved in the technical solution of the present application, they are the same as the prior art or can be implemented by the prior art, and will not be elaborated here.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
