Description

Technical Field

[0001] The present invention relates to the technical field of boiler room water make-up, and particularly to a boiler room water make-up and exhaust device. Background Art

[0002] Vacuum exhaust during boiler room water make-up is a key link in boiler operation. Its purpose is to maintain the boiler water level by making up water, and use a vacuum exhaust device to effectively remove the air introduced during the water make-up process, ensuring the safe and efficient operation of the boiler system, and avoiding air affecting the boiler thermal efficiency and causing potential safety hazards.

[0003] In currently existing vacuum degassing units, the exhaust work is generally achieved by continuously pumping vacuum. As the gas in the system is continuously pumped out, the gas release rate exceeds its dissolution rate in the liquid, breaking the original dissolution-release equilibrium state, thereby prompting the gas to be continuously separated from the liquid. However, when the system reaches a stable vacuum level, the gas release and dissolution will gradually tend to a new equilibrium state, and at this time, the degassing rate will significantly slow down. It should be noted that many existing vacuum degassing units are not convenient for performing cyclic vacuum pumping operations. For some gases with high solubility in liquids or difficult to spontaneously release, a single vacuum pumping treatment may not be able to completely remove them. In addition, in the vacuum degassing process, the presence of tiny bubbles in the circulating water is still a challenge. These bubbles enclose air inside and are not easily broken, resulting in the retained air being unable to be effectively removed, thereby affecting the overall degassing effect. In view of the above problems, it is particularly crucial and meaningful to develop an innovative boiler room water make-up and exhaust device aimed at overcoming the limitations of the existing technology. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments.

[0041] Embodiment 1

[0042] As Figures 1-4 and Figures 6-10 shown, the present invention provides a technical solution: a boiler room water replenishment and exhaust device, including a water replenishment and exhaust device 100, and a vacuum mechanism 200 is installed on the water replenishment and exhaust device 100;

[0043] The vacuum mechanism 200 includes a vacuum component 201, and the vacuum component 201 includes a vacuum tank 2011. The piston cylinder 209 is installed above the vacuum tank 2011, and the gear ring 204 is fixedly installed in the vacuum tank 2011. A connector 2016 is installed at the bottom of the vacuum tank 2011, and the connector 2016 can be connected to the water replenishment and exhaust equipment 100, so that the liquid in the vacuum tank 2011 can be output. The connector 2016 is connected to the water replenishment and exhaust equipment 100. Water receiving ends 2012 and vacuum joints 2013 are respectively installed on both sides of the vacuum tank 2011. The water receiving ends 2012 can be connected to the water delivery equipment, so that water can be injected into the vacuum tank 2011. Secondly, the vacuum equipment can be connected to the vacuum joint 2013, so that the vacuum tank 2011 can be smoothly evacuated. An exhaust valve is installed above the vacuum tank 2011. 2014 and a pressure gauge 2015. The exhaust valve 2014 can be used to exhaust the vacuum tank 2011 to avoid excessive pressure inside the vacuum tank 2011. The pressure gauge 2015 can detect the internal pressure of the vacuum tank 2011. A support frame 215 is installed inside the vacuum tank 2011. The drum 213 is rotatably installed on the support frame 215 through a bearing. The drum 213 can maintain stable rotation through the bearing, so that the fixed frame 2162 maintains stable rotation. A first stirring component 216 and a plurality of second stirring components 202 are arranged inside the vacuum component 201. The plurality of second stirring components 202 are arranged longitudinally, and the plurality of second stirring components 202 are connected in transmission through a chain transmission component 205. The upper part of the chain transmission component 205 is also connected in transmission with the transmission component 203. One end of the transmission component 203 is connected in transmission with a gear ring 204.

[0044] Above the first stirring assembly 216, a rotary drum 213 is fixedly connected. A spiral groove 214 is provided inside the rotary drum 213. A rotary drive assembly 207 is slidably connected in the spiral groove 214. The rotary drive assembly 207 penetrates upward through the piston cylinder 209 and is connected to the sealing plug 217. Two air vents 218 are provided on the sealing plug 217. A valve assembly 208 is arranged in the air vents 218. The valve assembly 208 includes a valve rod 2082 and four groups of connecting pieces 2084. A sealing ball 2081 is installed on the valve rod 2082. The lower part of the air vent 218 is conical. Through the conical setting of the air vent 218, the sealing ball 2081 can smoothly close the air vent 218. The sealing ball 2081 seals the air vent 218. The number of each group of articulated frames 2083 is two. Four of the articulated frames 2083 are fixedly connected to the valve rod 2082. Both of the two articulated frames 2083 are respectively articulated to the two connecting pieces 2084 through pin shafts. A telescopic rod 2085 and a first spring 2086 are fixedly connected between the two connecting pieces 2084. When the valve rod 2082 contacts the retaining ring 2066 downward, the valve rod 2082 drives the sealing ball 2081 to move upward. At the same time, the first spring 2086 deforms and turns. When the first spring 2086 crosses the horizontal line, the first spring 2086 resets, thereby positioning the position of the sealing ball 2081, enabling the second spring 210 to smoothly drive the sealing plug 217 to complete the upward reset. When the valve rod 2082 contacts the top wall of the piston cylinder 209 upward, at this time, the valve rod 2082 drives the sealing ball 2081 to close the air vent 218 downward, so that a new round of vacuum pumping operation can be carried out again. And the sealing plug 217 is arranged in the piston cylinder 209. The piston cylinder 209 is assembled above the vacuum assembly 201. A piston position adjustment assembly 206 is arranged through the piston cylinder 209 and the sealing plug 217. The piston position adjustment assembly 206 includes a handle 2062. A screw rod 2061 is fixedly connected below the handle 2062. The screw rod 2061 is rotatably installed on the piston cylinder 209 through a bearing. A nut 2063 is threadedly connected to the screw rod 2061. A connecting plate 2064 is fixedly installed on the nut 2063. Two slide rods 2065 are fixedly connected below the connecting plate 2064. The two slide rods 2065 penetrate downward through the piston cylinder 209 and the sealing plug 217 and are fixedly connected to the retaining ring 2066. By rotating the screw rod 2061 through the handle 2062, the screw rod 2061 and the nut 2063 are in threaded transmission, so that the nut 2063 drives the connecting plate 2064 and the slide rods 2065 to move. The slide rods 2065 adjust the up and down position of the retaining ring 2066, thereby adjusting the distance between the retaining ring 2066 and the valve rod 2082, facilitating adjusting the movement stroke of the sealing plug 217 according to actual needs for reciprocating vacuum pumping operation. Secondly, when the retaining ring 2066 is lowered to the bottom wall position of the piston cylinder 209, at this time, the valve rod 2082 no longer contacts the retaining ring 2066 downward, so that it is possible to choose whether to perform reciprocating vacuum pumping operation according to requirements. A filter port 212 is installed above the piston cylinder 209.The ventilation above the sealing plug 217 can be maintained through the filtering port 212, enabling the smooth movement of the sealing plug 217. Moreover, the filtering port 212 can filter the gas. A retaining ring 211 is fixedly connected to the lower part of the inner cavity of the piston cylinder 209. The downward position of the sealing plug 217 can be limited by the retaining ring 211. A second spring 210 is fixedly connected to the bottom wall of the piston cylinder 209. The second spring 210 can drive the sealing plug 217 to reset upward. And the elastic potential energy of the second spring 210 is greater than the elastic potential energy of the first spring 2086, so that the valve stem 2082 can overcome the elastic force of the first spring 2086 when it contacts the top wall of the piston cylinder 209 upward, and then the valve stem 2082 can move downward smoothly. The top end of the second spring 210 is fixedly connected to the sealing plug 217. The piston position adjusting assembly 206 extends downward to the lower part of the inner cavity of the piston cylinder 209.,

[0045] In this embodiment, through the vacuum joint 2013 and the vacuum equipment, at this time, the vacuum tank 2011 can be evacuated by the vacuum equipment. During the evacuation process, the sealing plug 217 moves downward and drives the deformation of the second spring 210. When the valve stem 2082 contacts the retaining ring 2066 downward, at this time, the valve stem 2082 drives the sealing ball 2081 to move upward, and the sealing ball 2081 automatically opens the ventilation port 218, enabling the second spring 210 to release the elastic force and reset, and the sealing plug 217 resets upward until the valve stem 2082 contacts the top wall of the piston cylinder 209 upward, causing the valve stem 2082 to drive the sealing ball 2081 to close the ventilation port 218. At this time, the vacuum operation can be carried out again. By repeating this process, the reciprocating evacuation operation can be realized, which is conducive to the rapid release of gas, improves the degassing shrinkage rate, and facilitates the complete removal of gas.

[0046] Embodiment 2

[0047] Combined with Figure 5 and Figures 7-8 it is obtained that: The first stirring assembly 216 includes a fixing frame 2162. The top of the fixing frame 2162 is fixedly connected to the rotating cylinder 213. Turbulence generating vanes 2161 are fixedly connected to the middle parts on both sides of the fixing frame 2162. By driving the turbulence generating vanes 2161 to rotate through the fixing frame 2162, the turbulence generating vanes 2161 can stir the liquid to eliminate bubbles;

[0048] The transmission assembly 203 includes a rotating shaft 2032. The rotating shaft 2032 is rotatably installed on the fixing frame 2162 through two bearings. One end of the rotating shaft 2032 is fixedly connected to a gear 2031. The gear 2031 meshes with the gear ring 204. Through the transmission between the gear 2031 and the gear ring 204, the power transmission can be realized, and thus the chain transmission assembly 205 can be driven to rotate;

[0049] The second stirring assembly 202 includes a stirring shaft 2021, which is rotatably mounted on a fixed frame 2162 via two bearings. Both ends of the stirring shaft 2021 are fixedly connected with a plurality of stirring blades 2022. The stirring shaft 2021 drives the stirring blades 2022 to rotate, so that the stirring blades 2022 move up and down to cooperate with the spoiler 2161 to perform flow disturbance operations on the liquid in different directions, thereby improving the efficiency of bubble elimination;

[0050] The rotation driving assembly 207 includes a movable rod 2071, the top end of which is fixedly connected to the sealing plug 217, and the movable rod 2071 passes through the piston cylinder 209 and is fixedly connected to two roller rods 2072. The roller rods 2072 slide in the spiral groove 214, so that the roller rods 2072 can control the rotation of the rotating drum 213 through the arc surface of the spiral groove 214, thereby driving the first stirring assembly 216 to realize the rotation. The two roller rods 2072 slide in the spiral groove 214;

[0051] The chain drive assembly 205 includes multiple sprockets 2051, and the multiple sprockets 2051 are respectively fixedly mounted on the rotating shaft 2032 and the multiple stirring shafts 2021. The multiple sprockets 2051 are connected through the chain 2052. The chain 2052 can be meshed with the multiple sprockets 2051 to achieve synchronous rotation between the multiple sprockets 2051, so that the multiple stirring shafts 2021 can achieve synchronous rotation.

[0052] In this embodiment: vacuuming operation is performed by moving the sealing plug 217 up and down, so that the sealing plug 217 drives the movable rod 2071 to move up and down, and the movable rod 2071 drives the roller rod 2072 to move up and down, and the roller rod 2072 drives the fixed frame 2162 and the spoiler 2161 to rotate through the arc surface of the spiral groove 214. At the same time, the fixed frame 2162 drives the first stirring component 216 and the transmission component 203 to revolve, so that the gear 2031 and the ring gear 204 are transmitted, the gear 2031 drives the rotating shaft 2032 to rotate, and the rotating shaft 2032 can drive the sprocket 2051 to rotate. Under the transmission of the chain 2052, multiple sprockets 2051 rotate synchronously, and multiple stirring shafts 2021 rotate synchronously. The stirring shaft 2021 drives the stirring blade 2022 to rotate up and down. This method can realize the turbulence operation of the liquid in the vacuum tank 211 in different directions, so that the bubbles in the liquid can be easily eliminated, thereby significantly improving the exhaust effect.

[0053] Example 3

[0054] Combination Figure 4 , Figures 6-7 and Figure 9, it is obtained that: the vacuum mechanism 200 includes a vacuum assembly 201, a first stirring assembly 216 and a plurality of second stirring assemblies 202 are arranged inside the vacuum assembly 201. The plurality of second stirring assemblies 202 are longitudinally arranged, and the plurality of second stirring assemblies 202 are drivingly connected through a chain drive assembly 205. Above the chain drive assembly 205 is also drivingly connected to a drive assembly 203, and one end of the drive assembly 203 is drivingly connected to a gear ring 204;

[0055] Above the first stirring assembly 216 is fixedly connected with a rotating cylinder 213. A spiral groove 214 is opened inside the rotating cylinder 213. A rotary drive assembly 207 is slidably connected in the spiral groove 214. The rotary drive assembly 207 passes through the piston cylinder 209 upward and is connected to a sealing plug 217. Two air vents 218 are opened on the sealing plug 217. A valve assembly 208 is arranged in the air vents 218. The sealing plug 217 is arranged in the piston cylinder 209. The piston cylinder 209 is assembled above the vacuum assembly 201. A piston position adjusting assembly 206 passes through the piston cylinder 209 and the sealing plug 217. The piston position adjusting assembly 206 extends downward to the lower part of the inner cavity of the piston cylinder 209.

[0056] In this embodiment: the vacuum tank 2011 is evacuated by a vacuum device. The evacuation can drive the sealing plug 217 to move downward. The sealing plug 217 deforms the second spring 210. When the valve assembly 208 contacts the retaining ring 2066 downward, the valve assembly 208 opens the air vent 218. At this time, the second spring 210 drives the sealing plug 217 to reset upward until the valve assembly 208 contacts the top wall of the piston cylinder 209 upward to close the air vent 218. In this way, the reciprocating evacuation operation can be carried out. During the evacuation process, the sealing plug 217 also drives the rotary drive assembly 207 to move, so that the rotary drive assembly 207 cooperates with the spiral groove 214 to realize the revolution of the first stirring assembly 216 and the second stirring assemblies 202. At the same time, the drive assembly 203 can be in transmission with the gear ring 204, and the chain drive assembly 205 is linked to drive the second stirring assemblies 202 to rotate, so that the liquid inside the vacuum tank 2011 flows in different directions, thereby the efficiency of eliminating bubbles can be accelerated, and at the same time, the exhaust effect can be greatly improved by cooperating with the reciprocating evacuation, so that the overall processing efficiency can be improved.

[0057] The working principle of the present invention is as follows: Water is injected into the vacuum tank 2011 through the water receiving end 2012 connected to the water conveying device. During the vacuum pumping operation, the vacuum device is connected through the vacuum joint 2013, and then the vacuum pumping operation is carried out. During the vacuum pumping process, the sealing plug 217 moves downward, and the sealing plug 217 squeezes the second spring 210 downward. When the valve stem 2082 contacts the retaining ring 2066 downward, the valve stem 2082 drives the sealing ball 2081 to move upward. At the same time, the upward movement of the valve stem 2082 can drive the first spring 2086 and the telescopic rod 2085 to deflect. When it exceeds the horizontal point, the first spring 2086 is reset obliquely upward, fixing the position of the sealing ball 2081. At this time, the vent 218 is opened, and the second spring 210 drives the sealing plug 217 to reset upward. When the valve stem 2082 contacts the top wall of the piston cylinder 209 upward, at this time, the valve stem 2082 drives the sealing ball 2081 to reset downward, closing the vent 218 with the sealing ball 2081. At this time, the vacuum pumping operation continues, causing the sealing plug 217 to continue to move downward, and the vacuum pumping operation is carried out reciprocally, and then the exhaust operation can be carried out;

[0058] When the sealing plug 217 moves up and down, the sealing plug 217 drives the movable rod 2071 to move up and down, and the movable rod 2071 drives the roller rod 2072 to move up and down, causing the roller rod 2072 to slide in the spiral groove 214. And the roller rod 2072 controls the rotation of the rotating cylinder 213 through the arc surface of the spiral groove 214. The rotating cylinder 213 drives the fixed frame 2162 to rotate, and the fixed frame 2162 drives the spoiler 2161 to rotate. At the same time, the fixed frame 2162 drives the second stirring assembly 202 to revolve, and the transmission assembly 203 rotates following the fixed frame 2162, enabling the gear 2031 to drive with the gear ring 204. The gear 2031 drives the rotating shaft 2032 to rotate, and the rotating shaft 2032 drives the sprocket 2051 to rotate. The sprocket 2051 meshes and drives with the chain 2052, causing multiple sprockets 2051 to rotate synchronously, and now enabling the stirring shaft 2021 to rotate synchronously. The stirring shaft 2021 drives the stirring blades 2022 to rotate, causing the stirring blades 2022 and the spoiler 2161 to carry out turbulent flow operations on the liquid in different directions, eliminating bubbles, and then cooperating with the vacuum pumping to achieve a better exhaust operation.
