Description

Technical Field

[0001] This utility model relates to the field of vacuum deaerator technology, specifically to a descaling vacuum deaerator. Background Technology

[0002] A vacuum deaerator is a device that boils water at a low temperature under vacuum to remove gases such as oxygen, nitrogen, and carbon dioxide. It consists of two main parts: a deaerator tank (deaerator tower) and a vacuum unit.

[0003] Currently, vacuum deaerators lack auxiliary descaling mechanisms. During operation, water typically contains various minerals and suspended solids. As water flows and temperature changes during deoxygenation, some low-solubility minerals, such as calcium and magnesium carbonates and sulfates, may precipitate due to supersaturation, forming deposits that adhere to the inner wall of the deaerator. Therefore, this descaling vacuum deaerator is proposed to incorporate an auxiliary descaling mechanism. Utilizing rotation, flow guidance, and cleaning methods, it increases the contact area and range between water and steam, while simultaneously cleaning the inner wall of the deaerator, scraping away residual deposits to prevent long-term buildup and scale formation, thereby improving performance. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is a descaling vacuum deaerator, including a deaerator water tank, a deaerator tower and a vacuum pump. The top of the deaerator water tank is bolted to the deaerator tower. The top of the deaerator water tank is bolted to one side of the deaerator tower and the vacuum pump is bolted to it.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] To increase the contact area and range between water and steam, and to assist in cleaning the inner wall of the deaerator, thereby improving its performance, such as... Figure 1-3 As shown, the descaling vacuum deaerator of this utility model includes a deaeration water tank 1, a deaeration tower 2, and a vacuum pump 3. The top of the deaeration water tank 1 is bolted to the deaeration tower 2. The top of the deaeration water tank 1 is bolted to one side of the deaeration tower 2, and the vacuum pump 3 is bolted to the side of the deaeration tower 2. The air inlet of the vacuum pump 3 is connected to the deaeration tower 2 through a pipe. A flow guiding component 4 is provided at the top of the deaeration tower 2. A rotating rod 5 is provided at the bottom of the flow guiding component 4. A cleaning component 6 is provided around the rotating rod 5. A recovery component 7 is provided at the bottom of the cleaning component 6 inside the deaeration tower 2.

[0025] The cleaning component 6 includes a stirring blade 601, and the stirring blade 601 is connected to a rotating rod 5 by bolts. A push rod 602 is sleeved on the inner side of the stirring blade 601. One end of the push rod 602 is connected to a push plate 603 by bolts. Scraper blades 604 are welded to both sides of the push plate 603.

[0026] In use, the stirring blade 601, rotating rod 5, push rod 602, push plate 603 and scraper 604 can be used to add an auxiliary cleaning mechanism. By using rotation, diversion and cleaning, the inner wall can be cleaned to remove the deposits attached to the surface and reduce the generation of dirt.

[0027] To improve the quality of descaling and recovery, for example, such as Figure 2 , Figure 4 As shown, the present invention also includes the following: the recycling component 7 includes an annular frame 701, and the deaerator 2 is connected to the annular frame 701 by bolts; a filter plate 702 is fixedly installed in the annular frame 701 by a slot.

[0028] During use, an auxiliary recycling mechanism can be added through the ring frame 701 and filter plate 702 to assist in the recycling of the cleaned dirt through filtration and recycling.

[0029] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a compression spring 605 fixedly installed inside the stirring blade 601 on the inner side of the push rod 602 via a slot, and a rotary motor 8 is provided at the bottom of the deaerator 2, and the rotary motor 8 is connected to the rotating rod 5 via a drive shaft.

[0030] During use, the compression spring 605 facilitates the automatic sliding of the push rod 602 outward by using elastic force, ensuring the quality of auxiliary cleaning. The rotary motor 8 facilitates the reciprocating rotation of the rotating rod 5.

[0031] For example, such as Figure 5 As shown, the present invention also includes a flow guiding component 4 comprising a sleeve 401, the sleeve 401 being bolted to the top of the deaerator 2, a rotating roller 402 being mounted inside the sleeve 401 via a bearing, a spiral blade 403 being bolted to the periphery of the rotating roller 402, and a flow guiding cover 404 being bolted to the bottom of the sleeve 401.

[0032] In use, the sleeve 401, rotating roller 402, spiral blade 403 and guide shroud 404 can make the residual moisture in the steam come into contact with the spiral blade 403 to form water droplets, which are then recycled under their own weight.

[0033] For example, such as Figure 2 As shown, the present invention also includes a swirl film tube 201 located at the bottom of the flow guiding component 4 inside the deaerator 2, a first water inlet 202 opened on one side of the deaerator 2, and a second water inlet 203 opened on the other side of the deaerator 2, and both the first water inlet 202 and the second water inlet 203 are connected to the swirl film tube 201.

[0034] During use, softened water can be easily transported to the deoxygenation tower 2 for auxiliary deoxygenation through the swirl tube 201 and the first inlet 202, and cleaning agent can be easily pumped in for auxiliary flushing and descaling when the machine is stopped through the second inlet 203.

[0035] For example, such as Figure 2 As shown, this utility model also includes a steam pipe 204 located at the bottom of the swirl film tube 201 inside the deaerator tower 2, a steam nozzle 205 located at the top of the steam pipe 204, a steam inlet 206 opened on one side of the surface of the deaerator tower 2, and the steam inlet 206 is connected to the steam pipe 204. A second steam inlet 207 is opened at the bottom of the steam inlet 206 on one side of the deaerator tower 2. A water spray grate 208 is arranged inside the deaerator tower 2 between the steam pipe 204 and the second steam inlet 207. A water collection hood 209 is arranged inside the deaerator tower 2 at the bottom of the water spray grate 208.

[0036] In use, the steam pipe 204, steam nozzle 205, steam inlet 206, second steam inlet 207, water spray grate 208 and water collection hood 209 can be used to perform heat exchange and deoxygenation treatment on the water, and then the water can be recycled by guiding the flow.

[0037] In use, the vacuum pump 3 is manually activated to create a vacuum in the deaerator tower 2 via a connecting pipe. Condensate or demineralized water, supplied by the feed pump, enters the swirl tube 201 through the first inlet 202 and flows out from the bottom of the swirl tube 201 as swirl water. Simultaneously, steam enters the steam pipe 204 through the steam inlet 206 and is sprayed upwards from the steam nozzle 205. Through contact with the swirl water, oxygen is separated from the water. Driven by the vacuum pump 3, the steam, along with some unused steam, passes through the guide shroud 404 into the sleeve 401. The moisture in the steam forms droplets that contact the spiral blades 403 and fall under gravity, along with the deaerated water, through the water grate. The atomized water 208 is further deoxygenated by heat exchange with the steam entering through the second steam inlet 207. The deoxygenated water falls into the deoxygenated water tank 1 for storage. During deoxygenation, the rotary motor 8 can be manually turned on to drive the rotating rod 5 to rotate the stirring blade 601, so that the steam and deoxygenated water can come into full contact, thereby improving the deoxygenation efficiency. At the same time, under the elastic force of the spring 605, the push rod 602 pushes the push plate 603 to slide to the inner wall of the deoxygenation tower 2. The scraper 604 uses rotational friction to assist in cleaning the inner wall surface, thereby reducing the residue of sediment. To further improve the descaling and cleaning quality, a cleaning agent can be pumped in through the second water inlet 203 and sprayed on the inner wall surface of the deoxygenation tower 2 to improve the cleaning and descaling effect.

[0038] The dirt scraped off falls onto the filter plate 702 of the ring frame 701 under its own weight, so that the operators can carry out auxiliary cleaning and maintenance. The overall structure is simple, more reasonable and reliable in use, and has high practical value.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
