Description

Technical Field

[0001] The utility model relates to the technical field of condenser cleaning, in particular to a rubber ball cleaning system. Background Art

[0002] The condenser is one of the key equipment in a thermal power plant. It plays an important role in condensing the unsaturated steam in the turbine into water. However, due to long-term operation and the accumulation of scale in the circulating cooling water, the heat exchange effect of the condenser gradually decreases. In order to improve the heat exchange effect of the condenser, a rubber ball cleaning system is generally used to regularly clean the stainless steel pipes of the condenser.

[0003] The rubber ball cleaning system usually includes a ball receiving room, a ball return pipe, a ball outlet pipe, a rubber ball pump and a ball receiving net. One end of the ball receiving room is connected to the water inlet pipe of the condenser through the ball outlet pipe, and the other end of the ball receiving room is connected to the water outlet pipe of the condenser through the ball return pipe. The ball return pipe is provided with a ball receiving net and a rubber ball pump. When the rubber ball pump is started, the rubber balls in the ball receiving room circulate in the pipeline system composed of the ball outlet pipe, the condenser and the ball inlet pipe under the action of water pressure to clean the condenser. After the cleaning is completed, the ball receiving room stops discharging balls, and the rubber ball pump continues to work until all the rubber balls in the pipeline system return to the ball receiving room, and then the rubber ball pump is turned off. Due to the pressure difference between the inlet and outlet pipes of the condenser, after the rubber ball pump is turned off, the water flow in the cleaning pipeline will flow in the reverse direction, and the rubber balls originally returned to the ball receiving room will be flushed to the rubber ball pump or the ball receiving net again, which not only accelerates the wear of the rubber balls, but also increases the return water resistance, affecting the safety of system operation.

[0004] In order to prevent the rubber balls from flowing back, a valve is usually installed on the pipeline between the ball collecting room and the rubber ball pump. After all the rubber balls in the pipeline system return to the ball collecting room, the valve and the rubber ball pump are closed. Although this can prevent the rubber balls from flowing back to the rubber ball pump and the ball collecting net to a certain extent, some rubber balls will still remain in the pipeline between the valve and the ball collecting room. The ball collecting rate of the ball collecting room is low, or the balls are blocked in the valve, causing the valve to get stuck and the operation of the entire cleaning system to become abnormal.

[0026] In this article, an XYZ coordinate system is established, and it should be noted that the aforementioned X-axis, Y-axis, and Z-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] The existing valves set on the pipeline between the ball collecting room and the rubber ball pump include manual ball valves and check valves. When setting the manual ball valve, there are two control methods: first close the manual ball valve and then close the rubber ball pump, or first close the rubber ball pump and then close the manual ball valve. If the former is selected, there will not only be problems such as the rubber ball blocking the manual ball valve and the rubber ball flowing back to the pipeline between the manual ball valve and the ball collecting room, which is inconvenient to count and has a low ball collection rate, but also the rubber ball pump will be pressurized, the bearing seal of the pump body will be easily damaged and leak, and even the pump body will burst, and the system operation stability will be poor; if the latter is selected, the rubber ball will seriously flow back during the period between closing the rubber ball pump and closing the manual valve, and the hand ball effect will be poor. When setting the check valve, when closing the rubber ball pump, the check valve is closed at the same time, and there will be rubber balls retained in the pipeline between the ball collecting room and the check valve, which is inconvenient to clean and count, has a low ball collection rate, and is prone to the phenomenon of rubber balls blocking the check valve.

[0028] like Figure 1-Figure 3 As shown, a rubber ball cleaning system of an embodiment of the utility model includes a ball receiving chamber 1, a ball return tube assembly 2 and a check mechanism 3, wherein the ball return tube assembly 2 includes a ball return tube 21, one end of the ball return tube 21 extends into the ball receiving chamber 1, and the check mechanism 3 includes a check plate 31, the upper portion of the check plate 31 is rotatably connected to the end of the ball return tube 21 extending into the ball receiving chamber 1, and the rotation axis is perpendicular to the axis of the pipe mouth, and the check plate 31 is used for rotating the cover arranged at the pipe mouth.

[0029] Specifically, the ball receiving chamber 1 can be a cylindrical structure arranged along the direction shown by the Z axis, and a rubber ball pump is provided on the ball return pipe 21. The ball return pipe 21 can be a circular tube. One end of the ball return pipe 21 extends into the ball receiving chamber 1, and the other end of the ball return pipe 21 is connected to the condenser. The rubber balls flowing out of the ball outlet of the ball receiving chamber 1 enter the condenser through the pipeline, and finally return to the ball receiving chamber 1 from the ball return pipe 21.

[0030] A circular check plate 31 is provided at the mouth of the ball return tube 21. The check plate 31 is located at the end of the ball return tube 21 extending into the ball receiving chamber 1, and can be fitted with the end surface of the mouth of the ball return tube 21 to block the mouth of the ball return tube 21. The end of the ball return tube 21 extending into the ball receiving chamber 1 is generally horizontally arranged (i.e. arranged along the direction indicated by the Y axis or inclined relative to the Y axis), and the upper part of the check plate 31 is connected to the top wall of the ball return tube 21 by hinges, rotating shafts, hinges, etc. to achieve vertical rotation around the rotation axis (i.e. the axis parallel to the direction indicated by the X axis). The check plate 31 can be turned upward relative to the ball return tube 21 under the action of water pressure to open, and can also be turned downward relative to the ball return tube 21 under the action of gravity to close the ball return tube 21.

[0031] In this embodiment, when the rubber ball cleaning system is working, that is, the rubber ball pump on the ball return pipe 21 is started, the water pressure pushes the check plate 31 to flip upward relative to the ball return pipe 21, the pipe mouth of the ball return pipe 21 is opened, and the rubber balls coming out of the ball receiving chamber 1 enter the condenser and return to the ball receiving chamber 1 through the ball return pipe 21, and the reciprocating cycle is carried out to clean the condenser; when all the rubber balls return to the ball receiving chamber 1, the rubber ball cleaning system stops working, that is, the rubber ball pump is closed, and the check plate 31 rotates downward relative to the ball return pipe 21 under the action of gravity, and fits with the pipe mouth end face of the ball return pipe 21 under the impact of the backflow water, and the ball return pipe 21 is blocked, which effectively avoids the problem of the backflow water flushing the rubber balls in the ball receiving chamber 1 back to the ball return pipe and the rubber balls clogging the valve, making the cleaning and counting of the rubber balls more convenient, the ball collection rate is higher, and the overall operation of the cleaning system is safer. In addition, at the moment of closing the rubber ball pump, the check plate is automatically closed. Compared with the manual closing of the valve, the operation is more convenient and efficient. Compared with the closing of the valve first and then the rubber ball pump, the rubber ball pump has no pressure holding phenomenon, the service life of the rubber ball pump is longer, and the system operation is safer and more reliable. Moreover, the ball return pipe 21 extends into the ball receiving chamber 1, and the rubber ball enters the internal space of the ball receiving chamber 1 along the ball return pipe 21 and then is output from the ball return pipe 21, which is conducive to the uniform diffusion of the rubber ball in the ball receiving chamber 1 and avoids the rubber ball blocking the outlet of the ball return pipe.

[0032] like Figure 2 As shown, optionally, the check mechanism 3 also includes a connecting seat 32, a rotating shaft 33 and a connecting ear 34, the connecting seat 32 is arranged on the outer wall of the ball return tube 21, the connecting ear 34 is provided on the upper part of the check plate 31, the connecting ear 34 is rotatably connected to the connecting seat 32 through the rotating shaft 33, the rotating shaft 33 passes through the connecting seat 32 and the connecting ear 34, and the axis where the rotating shaft 33 is located is the rotating axis.

[0033] Specifically, a connecting seat 32 is provided on the top of the outer wall of the ball return tube 21 , and an L-shaped connecting ear 34 can be welded and fixed on the upper part of the check plate 31 .

[0034] In this embodiment, the upper portion of the check plate 31 is rotatably connected to the connecting seat 32 on the ball return tube 21 via a rotating shaft 33 arranged along the direction indicated by the X-axis, thereby realizing the up and down rotational connection of the check plate 31 relative to the ball return tube 21, and the connection method is simple.

[0035] like Figure 2 As shown, optionally, the check mechanism 3 also includes a limit plate 35, the connecting seat 32 is provided with two and is arranged opposite to each other, the connecting ear 34 is rotatably arranged between the two connecting seats 32, and the limit plate 35 is arranged on one side of the two connecting seats 32 close to the inner wall of the ball receiving room 1, and the limit plate 35 is used to abut against the connecting ear 34 when the check plate 31 is flipped upward to limit the upward flipping angle of the check plate 31.

[0036] Specifically, the two connecting seats 32 are spaced apart in the direction indicated by the X-axis, the connecting ears 34 extend between the two connecting seats 32, the rotating shaft 33 passes through the two connecting seats 32 and the connecting ears 34 in sequence, and the limiting plate 35 is arranged on the side of the two connecting seats 32 close to the inner wall of the ball receiving chamber 1, that is, the limiting plate 35 is located on the side of the rotating direction of the rotating shaft 33, including the limiting plate 35 is arranged between the two connecting seats 32, and the limiting plate 35 is arranged on the side of the end surface of the two connecting seats 32 close to the inner wall of the ball receiving chamber 1. The limiting plate 35 can be integrally formed with the connecting seat 32, and the limiting plate 35 and the two connecting seats 32 enclose a U-shaped structure with the opening facing the side of the check plate 31.

[0037] In this embodiment, when the check plate 31 rotates upward in the counterclockwise direction, it stops rotating when the connecting ear abuts against the limit plate 35, thereby limiting the rotation of the check plate 31 and preventing the check plate 31 from being unable to return to its original position under the action of gravity due to excessive upward rotation angle.

[0038] like Figure 2 As shown, optionally, the check mechanism 3 further includes a counterweight block 36 , and the counterweight block 36 is disposed at the lower portion of the check plate 31 .

[0039] Specifically, the counterweight block 36 can be a round block, which can be welded and fixed to the lower part of the check plate 31. The weight of the counterweight block 36 can be balanced according to the pressure of the rubber ball pump and the buoyancy of the check plate 31 in the ball receiving chamber 1. It should not be too light or too heavy. For example, the outlet pressure of the rubber ball pump is 0.3Mpa, and the weight of the counterweight block 36 is about 300 grams.

[0040] The weight of the check plate 31 is increased by providing the counterweight 36, so that when the rubber ball pump is turned off, the check plate 31 can rotate downward more quickly to block the pipe opening of the ball return pipe 21, and can also prevent the check plate 31 from floating up when the rubber ball pump is turned off to a certain extent.

[0041] Optionally, the check plate 31 and the connecting ear 34 are both made of stainless steel.

[0042] In this embodiment, the check plate 31 is made of stainless steel, mainly considering that the check plate 31 is in water for a long time, and the stainless steel material is corrosion-resistant, which can ensure that the check plate 31 will not be corroded and damaged. The connecting ear 34 on the upper part of the check plate 31 is made of stainless steel, which has a large rigidity, so that the connecting ear 34 can withstand the strong impact force of the rubber ball pump when starting, thereby extending the service life of the entire check mechanism.

[0043] like Figure 2-Figure 3As shown, optionally, the pipe opening at one end of the ball return pipe 21 extending into the ball receiving chamber 1 is an oblique pipe opening 211, and the pipe opening end face of the oblique pipe opening 211 is arranged to be inclined upward.

[0044] Specifically, the end of the ball return tube 21 extending into the ball receiving chamber 1 is provided with an inclined tube opening 211 inclined downward, that is, the projection of the upper part of the ball return tube 21 on the horizontal plane falls within the projection of the lower part of the ball return tube 21 on the horizontal plane. By providing the inclined tube opening 211 with the tube opening end face inclined upward, the check plate 31 is closely attached to the tube opening end face of the inclined tube opening 211 when rotating downward under the action of gravity, and the check plate 31 has a better blocking effect on the ball return tube 21, thereby preventing the rubber ball from flowing back.

[0045] Here, the included angle between the end face of the pipe mouth and the vertical plane (XZ plane) can be 15°, that is, the check plate 31 can be rotated downward by 75° relative to the horizontal plane, and then fit with the end face of the pipe mouth of the inclined pipe mouth 211 .

[0046] like Figure 1 and Figure 3 As shown, optionally, the ball receiving room 1 includes a ball receiving room body 11 and a ball receiving room cover 12 , one end of the ball receiving room body 11 is open to form a ball throwing opening 111 , and the ball receiving room cover 12 is used to cover the ball throwing opening 111 .

[0047] Specifically, the top of the ball receiving chamber body 11 is open to form a ball throwing opening 111, and the ball receiving chamber cover plate 12 is rotatably connected to the ball receiving chamber body 11, and the two are sealed.

[0048] In this embodiment, the ball receiving chamber cover 12 is opened upwards, and the rubber balls are thrown into the ball receiving chamber body 11 from the ball throwing port 111 to participate in the system circulation, which is convenient for timely replenishment of the rubber balls. After the rubber balls are replenished, the ball receiving chamber cover 12 is closed to ensure that no water stains will seep out when the system is in use.

[0049] In some embodiments, the ball receiving chamber cover 12 is provided with an observation port 121, an exhaust hole 122 and a handle 123. The observation port 121 can be made of a transparent material, through which the rubber balls in the ball receiving chamber body 11 can be observed. The handle 123 is convenient for lifting the ball receiving chamber cover 12. A threaded hole cover is provided at the exhaust hole 122. Opening the hole cover can eliminate the enclosed pressure in the ball receiving chamber body 11.

[0050] like Figure 1-Figure 3As shown, optionally, the ball receiving room 1 also includes a ball receiving frame 13, which is arranged in the ball receiving room body 11 and below the end of the ball return tube 21 extending into the ball receiving room 1, and the ball receiving frame 13 includes a filter screen cylinder 131, a lower ball tube 132 and a first valve 133. The upper part of the wall of the filter screen cylinder 131 is provided with filter holes, the upper end surface of the filter screen cylinder 131 extends radially to be connected to the inner wall of the ball receiving room body 11, the lower end of the filter screen cylinder 131 is connected to the lower ball tube 132, and the first valve 133 is arranged on the lower ball tube 132.

[0051] Specifically, the ball receiving frame 13 is arranged toward the ball pitching port 111, so as to facilitate the replenishment or removal of rubber balls from the ball pitching port 111. The filter screen cylinder 131 is located below the end of the ball return tube 21 extending into the ball receiving chamber 1. The rubber balls returning from the ball return tube 21 can smoothly fall into the ball receiving frame 13 under the action of gravity and the push of water flow, so as to facilitate the collection of balls. The filter screen cylinder 131 includes a straight cylindrical structure at the top and an inverted cone structure at the bottom. The straight cylindrical structure has a large capacity, which is conducive to collecting balls, and filter holes are arranged on its wall to facilitate water leakage; the inverted cone structure has a guiding function, and no filter holes are arranged on its wall, so it can store water, and the rubber balls can be carried by the water flow into the lower ball tube 132 and fall from the lower ball tube 132, so as to ensure the ball dropping effect.

[0052] In some other embodiments, the filter screen cylinder 131 may be an inverted cone structure as a whole, with filter holes provided at the upper portion of the inverted cone structure and no filter holes provided at the lower portion, which can also ensure the ball-loading effect.

[0053] The upper end surface of the filter screen cylinder 131 extends radially outward to form an edge to facilitate connection with the inner wall of the ball receiving chamber body 11, that is, there is a gap between the circumferential side wall of the filter screen cylinder 131 and the ball receiving chamber body 11, and the lower ball tube 132 is connected to the bottom of the filter screen cylinder 131. The water in the filter screen cylinder can enter the gap between the filter screen cylinder 131 and the ball receiving chamber body 11 from the filter holes on the circumferential side wall of the filter screen cylinder 131 and then flow out downward.

[0054] In this embodiment, when it is necessary to start cleaning the condenser, the first valve 133 is opened, and the rubber ball falls from the lower ball tube 132 into the lower space of the ball receiving chamber body 11, and water flows into the lower space of the ball receiving chamber body 11 from the gap between the lower ball tube 132 and the filter screen cylinder 131 and the ball receiving chamber body 11, and flows out from the ball outlet.

[0055] When it is necessary to stop cleaning, the first valve 133 on the lower ball tube 132 is closed. At this time, the rubber balls cannot be discharged downward and accumulate in the filter screen cylinder 131. However, the cleaning water can still pass through the filter holes and flow downward through the gap between the circumferential side wall of the filter screen cylinder 131 and the ball receiving chamber body 11. Furthermore, during the ball collecting process, the rubber balls in the entire cleaning system will only enter the ball receiving chamber body 11 and will not flow out of the ball receiving chamber body 11. After all the rubber balls have returned to the ball receiving chamber body 11, the rubber ball pump is turned off.

[0056] It should be noted that the diameter of the filter holes on the filter screen cylinder 131 is smaller than the diameter of the rubber ball.

[0057] like Figure 1 and Figure 3 As shown, optionally, the rubber ball cleaning system also includes a ball outlet pipe assembly 4, the ball outlet pipe assembly 4 includes a ball outlet pipe 41, the ball receiving chamber body 11 is arranged in an inverted cone-shaped bucket below the ball receiving frame 13, and one end of the ball outlet pipe 41 is connected to the inverted cone-shaped bucket.

[0058] Specifically, the inverted cone bucket has a converging effect, which increases the outflow speed of the rubber balls and water in the ball receiving chamber body 11. The end of the ball outlet pipe 41 away from the ball receiving chamber 1 is connected to the condenser. The rubber balls and water in the ball receiving frame 13 enter the lower space of the ball receiving chamber 1, and enter the ball outlet pipe 41 from the ball outlet, and finally reach the condenser.

[0059] like Figure 1 and Figure 3 As shown, optionally, the ball outlet pipe assembly 4 also includes a second valve 42 provided on the ball outlet pipe 41; and / or, the ball return pipe assembly 2 also includes a third valve 22 provided on the ball return pipe 21; and / or, the rubber ball cleaning system also includes a drain pipe assembly 5, and a section of the ball outlet pipe 41 between the second valve 42 and the ball receiving chamber 1 is connected to the drain pipe assembly 5, and when the second valve 42 and the third valve 22 are closed, the drain pipe assembly 5 is used for drainage.

[0060] Specifically, the drain pipe assembly 5 may include a drain pipe 51 and a fourth valve 52. The fourth valve 52 is arranged on the drain pipe 51. A section of the ball outlet pipe 41 between the second valve 42 and the ball receiving chamber 1 is connected to the drain pipe assembly 5, that is, the drain pipe 51 and an end of the ball outlet pipe 41 close to the ball outlet are connected to each other.

[0061] In this embodiment, when the cleaning system works normally, the fourth valve 52 is in a closed state.

[0062] When it is necessary to clean the interior of the ball receiving room 1 or to count the ball collection rate, first close the first valve 133 and the rubber ball pump to collect all the rubber balls into the ball receiving room 1, then close the second valve 42 and the third valve 22, open the exhaust hole 122 to relieve the pressure in the ball receiving room 1, and then open the fourth valve 52, and the water in the ball receiving room 1 is discharged from the drain pipe 51, so as to facilitate counting the number of rubber balls in the ball receiving room 1 and cleaning the ball receiving room 1.

[0063] It should be noted that the first valve 133 , the second valve 42 , the third valve 22 and the fourth valve 52 may be manual valves or electric valves.

[0064] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
