Description

Technical Field

[0001] The utility model relates to the technical field of a generator cooling water purification device, and specifically to a generator cooling water purification device. Background Art

[0002] A generator is a device that converts mechanical energy into electrical energy. Its operating principle is based on the law of electromagnetic induction. It mainly generates induced electromotive force by rotating mechanical parts cutting magnetic lines in a magnetic field, thereby outputting current. Generators are widely used in many fields such as power generation, industry, and transportation. The stator part of the generator will generate high temperature during use, and a cooling device is required to circulate and cool it to ensure the normal operation of the stator part. The circulation process of cooling water is that the cooling water in the stator is pumped out from the water tank through a cooling water pump - then the cooling water is connected to the exchanger through a pipe, and then cooled by the exchanger, and then the cooling water is adjusted by the temperature valve and flow valve, and then the impurities in the water are filtered, and then it will flow into the stator part, and then the high temperature carrying the wire rod will flow back to the water tank.

[0003] In the prior art, improper control of the water quality of cooling water in the generator causes the pH value of the cooling water to gradually decrease during use, resulting in a chemical corrosion reaction between the cooling water and the wire rods. The corrosion causes an increase in copper ions. After saturation is reached, the precipitated sediments will cause blockage inside the hollow conductor, causing the wire rod temperature to rise, and the equipment is forced to reduce load or shut down for maintenance, reducing the use effect of the generator.

[0005] The technical solution of the utility model is as follows:

[0006] A generator cooling water purification device comprises a cooling shell and a pH sensor, wherein the pH sensor is detachably fixedly connected to the cooling shell, and an inlet joint connected to an outlet end of a stator transmission compartment and an outlet joint connected to an inlet end of an internal cooling water tank are detachably fixedly connected to the upper and lower sides of the same side of the cooling shell, respectively, a first water storage tank is provided between the water inlet joint and the water outlet joint, a purification component for purifying cooling water is connected to the first water storage tank, a first gas delivery tank and a second gas delivery tank for transporting high-temperature gas precipitated from the cooling water are provided in the cooling shell, a transmission motor for driving the purification component is fixedly connected to the outer wall of the cooling shell, and a cover is detachably fixedly connected to the cooling shell.

[0007] Furthermore, the purification component includes a linkage column, which is slidably connected to the inner wall of the cooling shell, and a transmission rack is fixedly connected to the upper end of the linkage column. A transmission gear is meshed on one side of the transmission rack, and the transmission gear is rotatably connected in the cooling shell. The driving shaft of the transmission motor is coaxial with the transmission gear and is fixedly connected.

[0008] One end of the linkage column away from the transmission rack is rotatably connected to the first linkage plate, one side of the first linkage plate away from the transmission rack is fixedly connected to the transmission plate, and one end of the transmission plate away from the first linkage plate is fixedly connected to the second linkage plate.

[0009] Furthermore, the first linkage plate is coaxial with the first water storage tank and has a gap therebetween. A plurality of guide blocks are fixedly connected to the inner wall of the first water storage tank. A water stirring plate is rotatably connected to the upper side of the first linkage plate. The inner wall of the first water storage tank is a truncated cone that is narrow at the bottom and wide at the top.

[0010] Furthermore, a second water storage tank is provided on one side of the first water storage tank, a reflux tank and a discharge tank are provided on the upper and lower sides between the first water storage tank and the second water storage tank, respectively, the pH value sensor is detachably fixedly connected in the second water storage tank, and the second linkage plate abuts against the inner wall of the second water storage tank.

[0011] The transmission plate is provided with a drain hole, which is communicated with the drain groove. The transmission plate is in close contact with the inner wall of the first water storage groove on the side facing the drain groove.

[0012] A filter screen is fixedly connected to the inner wall of the reflux tank.

[0013] Furthermore, the first gas transmission tank and the second gas transmission tank are opened on the upper side of the second water storage tank.

[0016] Furthermore, the sealing cover is arranged above the second water storage tank.

[0017] The beneficial effects of the utility model are:

[0018] The purification component can change the cooling water flow rate through the first water tank, so that part of the cooling water is cooled by the accelerated flow, and at the same time, it can oscillate the cooling water. This oscillation can be fed back to the outlet end of the wire rod, impacting the sediment blocking the outlet end of the wire rod, thereby reducing the working temperature of the wire rod, thereby ensuring the stable operation of the equipment. The change in flow rate will change the pressure of the cooling water passing through the first water tank. Through the Bernoulli distance, the faster the flow rate, the smaller the pressure. When a flow rate difference occurs in the first water tank, a pressure difference is bound to occur, that is, the water outlet joint has a greater extraction force on the cooling water in the first water tank, causing the precipitated sediments to collide and break with each other, and are not easy to accumulate. Then, through the external filtering equipment, the water quality of the cooling water can be guaranteed, which further ensures the stability of the generator, so that the generator can operate stably for a long time.

DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 to Figure 6 As shown, this embodiment proposes a generator cooling water purification device, including a cooling shell 11 and a pH sensor 3, wherein the cooling shell 11 is connected between the generator stator part and the cooling water tank, the pH sensor 3 is detachably fixedly connected in the cooling shell 11, and a water inlet joint 12 connected to the outlet end of the stator transmission compartment and a water outlet joint 13 connected to the inlet end of the internal cooling water tank are detachably fixedly connected to the upper and lower sides of the same side of the cooling shell 11, respectively, and the water inlet joint 12 and the water outlet joint 13 are both standard parts, which have a fixed service life and need to be replaced, so a detachable fixed connection is adopted, such as a threaded connection, and a sealing tape is wrapped around the connected joint to ensure sealing;

[0029] Further explanation, the first water storage tank 111 is provided between the water inlet joint 12 and the water outlet joint 13, and the first gas delivery tank 115 and the second gas delivery tank 116 for delivering the high-temperature precipitated gas in the cooling water are both provided in the cooling shell 11. When the high-temperature and high-pressure cooling water flows into the second water storage tank 119, a large amount of carbon dioxide in the cooling water will be precipitated due to the high temperature. An air pump is connected to the outer end of the second gas delivery tank 116 to extract the precipitated carbon dioxide, and then the pH value of the cooling water transmitted by the pH sensor 3 is used to consider whether to inject ammonia into the cooling shell 11 through another air pump in the first gas delivery tank 115. In addition, the cooling water in the second water storage tank 119 can also be treated with alkali through the first gas delivery tank 115 to increase the pH value of the cooling water. When the pH value of the cooling water is greater than 8, the corrosion rate of copper is sharply reduced, that is, the service life of the wire rod is increased.

[0030] It is further explained that the purification component 2 for purifying the cooling water is connected to the first water storage tank 111, and the transmission motor 14 for driving the purification component 2 is fixedly connected to the outer wall of the cooling shell 11. The transmission motor 14 drives the purification component 2 to work. The purification component 2 can change the flow rate of the cooling water passing through the first water storage tank 111, so that part of the cooling water that accelerates the flow is cooled, and at the same time, the cooling water can be shaken. This shaking effect can be fed back to the outlet end of the wire rod, and the sediment blocking the outlet end of the wire rod is impacted, thereby reducing the working temperature of the wire rod, that is, ensuring the stable operation of the equipment. The change in flow rate will change the pressure of the cooling water passing through the first water storage tank 111. Through the Bernoulli distance, the faster the flow rate, the lower the working temperature of the wire rod. The faster the flow rate, the smaller the pressure. When a flow rate difference occurs in the first water tank 111, a pressure difference is bound to occur, that is, the water outlet joint 13 has a greater extraction force on the cooling water in the first water tank 111, so that the precipitated precipitates collide and break with each other, and are not easy to accumulate. Then, through the external filtering equipment, the water quality of the cooling water can be guaranteed, and the stability of the generator is further guaranteed, so that the generator can operate stably for a long time. The cover 16 is detachably fixedly connected to the cooling shell 11. Because the pH sensor 3 has a service life and the internal cavity of the cooling shell 11 needs to be kept closed, the connection between the cover 16 and the cooling shell 11 is a detachable fixed connection, such as a threaded connection, and a sealing tape is wrapped around the connection position to ensure sealing.

[0031] like Figure 1 to Figure 5As shown, the purification component 2 includes a linkage column 21, which is slidingly connected to the inner wall of the cooling shell 11, the upper end of the linkage column 21 is fixedly connected to the transmission rack 23, one side of the transmission rack 23 is meshed with the transmission gear 22, and the transmission gear 22 is rotatably connected in the cooling shell 11, and the driving shaft of the transmission motor 14 is coaxial and fixedly connected to the transmission gear 22. The end of the linkage column 21 away from the transmission rack 23 is rotatably connected to the first linkage plate 25, and the side of the first linkage plate 25 away from the transmission rack 23 is fixedly connected to the transmission plate 26, and the end of the transmission plate 26 away from the first linkage plate 25 is fixedly connected to the second linkage plate 27. The transmission gear 22 is an intermittent gear. The transmission gear 22 is driven by the transmission motor 14 to rotate one circle, which can drive the transmission rack 23 to move downward to the lowest position, and the downward-moving first linkage plate 25 can move the first linkage plate 25 to the second linkage plate 27. The water pressure on the lower side of the first linkage plate 25 oscillates, and this oscillation can act on the outlet end of the rod material, and can flush and oscillate the outlet section of the rod material, ensuring that the rod material is not easily blocked, so that the equipment can operate stably for a long time, and then the meshing part of the transmission gear 22 and the transmission rack 23 is separated, so that the first linkage plate 25 can be gradually moved upward under the action of the high temperature and high pressure on the lower side of the first linkage plate 25, and the cooling water flow rate through the gap between the first linkage plate 25 and the first water storage tank 111 is changed. The change in flow rate will lead to a change in pressure. When the flow rate is faster and the pressure is smaller, the suction force of the upper side of the first linkage plate 25 on the precipitate precipitated from the lower side of the first linkage plate 25 becomes greater, thereby making it difficult for the precipitate precipitated by the cooling water to precipitate, and it can be cleaned more cleanly, that is, the water quality of the cooling water is guaranteed.

[0032] like Figure 1 to Figure 3As shown, the first linkage plate 25 is coaxial with the first water storage tank 111 and a gap is left, so that when the high-temperature and high-pressure cooling water on the lower side of the first linkage plate 25 passes through the gap between the first linkage plate 25 and the first water storage tank 111, the flow rate increases, thereby reducing the temperature of the cooling water and accelerating the cooling effect of the cooling water. At this time, the upper side of the first linkage plate 25 is equivalent to the lower side of the first linkage plate 25 being in a negative pressure state, so that the upper side of the first linkage plate 25 can generate a greater suction force, so that the precipitate precipitated from the lower side of the first linkage plate 25 can be extracted by this suction force, thereby ensuring the water quality of the cooling water. A plurality of guide blocks 112 are fixedly connected to the inner wall of the first water storage tank 111, and a plurality of guide blocks 112 guide the cooling water passing through the gap between the first linkage plate 25 and the first water storage tank 111, so that the cooling water When water circulates, it can drive the water stirring plate 24 to rotate, so that the cooling water with a partially changed pH value can be mixed with the original cooling water more quickly when it flows back, that is, to ensure that the overall pH value of the cooling water is stable. The water stirring plate 24 is rotatably connected to the upper side of the first linkage plate 25. The inner wall shape of the first water storage tank 111 is a truncated cone with a narrow bottom and a wide top. When the first linkage plate 25 moves up and down under the action of high-pressure and high-temperature cooling water, the gap between the first linkage plate 25 and the first water storage tank 111 gradually increases, so that the flow rate of the cooling water passing through the first water storage tank 111 is always changing. The changing flow rate can repeatedly oscillate the cooling water, making it difficult for sediment precipitated in the cooling water to accumulate, thereby increasing the subsequent water quality filtration effect of the cooling water and ensuring the water quality of the cooling water.

[0033] like Figure 1 to Figure 5 As shown, the second water storage tank 119 is opened on one side of the first water storage tank 111, and the reflux tank 114 and the discharge tank 118 are respectively opened on the upper and lower sides between the first water storage tank 111 and the second water storage tank 119. The pH sensor 3 is detachably fixedly connected in the second water storage tank 119. The pH sensor 3 has a service life and needs to be replaced regularly, so it needs to be detachably fixedly connected. The second linkage plate 27 abuts against the inner wall of the second water storage tank 119. When the second linkage plate 27 moves upward, the cooling water on the upper side of the second linkage plate 27 will be moved upward, so that the second linkage plate 27 will bring this part of the cooling water into contact with the pH sensor 3, and return this part of the cooling water to the first water storage tank 111 through the reflux tank 114. The pH sensor 3 is not continuously soaked in the cooling water, so the corrosion rate of the cooling water to the pH sensor 3 is reduced, thereby increasing the service life of the pH sensor 3.

[0034] The drain hole 261 is opened on the transmission plate 26, and the drain hole 261 is communicated with the discharge groove 118. The transmission plate 26 is tightly abutted against the inner wall of the first water storage tank 111 facing the discharge groove 118. The high-temperature cooling water in the first water storage tank 111 can flow into the second water storage tank 119 through the drain hole 261 and the discharge groove 118. At the same time, when the transmission plate 26 moves upward, the drain hole 261 and the discharge groove 118 are no longer communicated, so that the first water storage tank 111 and the second water storage tank 119 become two independent cavities, thereby completing different working functions.

[0035] The filter screen 15 is fixedly connected to the inner wall of the reflux tank 114, so that when part of the cooling water whose pH value has been changed in the second water storage tank 119 flows back to the first water storage tank 111, it is filtered, and the precipitate precipitated from part of the cooling water is filtered to ensure the water quality of the cooling water in the first water storage tank 111.

[0036] like Figure 1 and Figure 2 As shown, the first gas delivery tank 115 and the second gas delivery tank 116 are opened on the upper side of the second water storage tank 119. When high-temperature and high-pressure cooling water flows into the second water storage tank 119, a large amount of carbon dioxide in the cooling water will be precipitated due to the high temperature. An exhaust pump is connected to the outer end of the second gas delivery tank 116 to extract the precipitated carbon dioxide, and then the pH value of the cooling water transmitted by the pH sensor 3 is used to consider whether to inject ammonia into the cooling shell 11 through another exhaust pump in the first gas delivery tank 115.

[0037] In addition, the cooling water in the second water storage tank 119 may be treated with alkali by the first gas delivery tank 115 to reduce the pH value of the cooling water.

[0038] like Figure 1 and Figure 2 As shown, a cooling tank 117 for cooling the cooling water in the second water tank 119 is opened on the upper side of the second water tank 119, and circulating water is injected into the cooling tank 117, and the cooling water in the second water tank 119 is cooled by the flowing water.

[0039] like Figure 1-2 and Figure 4 As shown, the transmission groove 113 is opened on the upper side of the first water storage tank 111, the transmission gear 22 abuts against the inner wall of the transmission groove 113, the linkage column 21 abuts against the inner wall of the transmission groove 113, and the transmission groove 113 is separated from the first water storage tank 111, so as to ensure that the cooling water will not directly contact the transmission gear 22, thereby ensuring that the transmission gear 22 can be used normally with the transmission rack 23.

[0040] like Figure 1-2As shown, the cover 16 is disposed above the second water storage tank 119. Because the pH sensor 3 has a service life and the inner cavity of the cooling shell 11 needs to be kept closed, the connection between the cover 16 and the cooling shell 11 is a detachable fixed connection.

[0041] The principle of this embodiment is:

[0042] The original circulation route of the generator cooling water is as follows: 1. The cooling water pump pumps out the water in the water tank → 2. The cooling water passes through the exchanger to reduce the water temperature → 3. The cooling water is regulated by the temperature valve and the flow valve → 4. The regulated cooling water is filtered by the filter device → 5. The cooling water flows in from the inlet end of the hollow part of the wire rod in the stator device and flows out from the outlet end of the hollow part of the wire rod, cooling the high temperature generated by the wire rod and transferring the heat → 6. The cooling water carrying the high temperature of the wire rod flows back to the water tank through the pipeline, completing a working closed loop;

[0043] The device is placed between the fifth step and the sixth step, and the modified partial circulation route is: 5. Cooling water flows in from the inlet end of the hollow part of the wire rod in the stator device and flows out from the outlet end of the hollow part of the wire rod, cooling the high temperature generated by the wire rod and carrying and transferring the heat → the cooling water flows into the purification device, the purification device cools and purifies the cooling water in the stator device, and at the same time, impacts and washes the outlet end of the hollow part of the wire rod to reduce the blockage of the outlet end of the wire rod and increase the cleaning effect of the sediment. At the same time, the flow rate of the purification device is always in a changing state, which can make sediments of different volumes collide with each other, break the sediments, and be discharged together with the cooling water → 6. The cooling water carrying the high temperature of the wire rod flows back to the water storage tank through the pipeline;

[0044] The high-temperature and high-pressure cooling water flowing out of the stator device flows into the first water storage tank 111 from the water outlet joint 13, and the operation starts when the cooling water fills the first water storage tank 111 and can flow out from the water inlet joint 12:

[0045] The transmission motor 14 is started to work, driving the transmission gear 22 to rotate half a circle, and then the transmission rack 23 moves downward, so that the first linkage plate 25 moves downward. The downward movement of the first linkage plate 25 is a fast action, so the first linkage plate 25 gives a shock impact to the cooling water on the lower side of the first linkage plate 25, so that part of the cooling water can flow back into the stator device and impact the sediment on the hollow outlet end of the wire rod. The cooling water that flows back is added to the cooling water that continuously enters from the other end of the stator device, so that the pressure in the stator device becomes larger, so that the sediment attached to the outlet end of the wire rod can be squeezed into the first water storage tank 111 by this pressure. Each downward movement of the first linkage plate 25 can flush the outlet end of the wire rod;

[0046] At the same time, because the inner wall shape of the first water storage tank 111 is a truncated cone that is wide at the top and narrow at the bottom, the first linkage plate 25 moves downward, and the gap between the first linkage plate 25 and the inner wall of the first water storage tank 111 will become smaller. When the high temperature on the lower side of the first linkage plate 25 passes through the gap, the flow rate will increase, and then the pressure will decrease. The cooling water on the lower side of the first linkage plate 25 will push the first linkage plate 25 upward. At the same time, the sediment squeezed into the lower side of the first linkage plate 25 can also move upward by the pressure difference generated by the flow rate, thereby increasing the cleaning effect of the sediment and ensuring the water quality of the cooling water. In addition, a part of the cooling water can also flow into the second water storage tank 119 through the drainage hole 261. When the first linkage plate 25 moves upward due to the water pressure, the second linkage plate 27 is also moved upward through the transmission plate 26. After the second linkage plate 27 moves upward, the drainage hole 261 will be staggered with the part that is connected to the drainage groove 118, so that the first water storage tank 111 and the second water storage tank 119 become independent and separated cavities. The cooling water of the second water storage tank 119 flows upward through the narrow channel on the upper side of the second water storage tank 119, and the pH sensor 3 detects the pH value of this part of the cooling water. Because the pH sensor 3 is not always immersed in the cooling water, the corrosion efficiency of the outer surface of the pH sensor 3 is reduced, thereby increasing the service life of the pH sensor 3. At the same time, because the carbon dioxide precipitated by high temperature can be extracted by the external vacuum pump through the second gas delivery tank 116, the carbon dioxide content in the cooling water is reduced, and the water quality of some cooling water can be improved. According to the inspection result of the pH sensor 3, ammonia or some alkaline materials can be injected into the second water storage tank 119 through the first gas delivery tank 115. The first gas delivery tank 115 and the second gas delivery tank 116 cannot work synchronously. Finally, the treated cooling water moves up to the reflux tank 114, and after being filtered by the filter screen 15, it will flow into the first water storage tank 111 and flow out from the water inlet joint 12 together with other original cooling water;

[0047] When the first linkage plate 25 moves down to the lowest position, when the cooling water passes through the gap between the first linkage plate 25 and the first water storage tank 111, it will be guided by the guide block 112, thereby causing the cooling water to swirl. This swirling cooling water can rotate with the stirring plate 24, so that part of the cooling water returning from the reflux tank 114 can be quickly mixed with the original cooling water, ensuring the overall stability of the cooling water quality.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
