Description

Technical Field

[0001] This application relates to the technical field of cleaning condenser balls in thermal power plants, and in particular to a condenser ball separator. Background Technology

[0002] Condensers in general thermal power plants need to be cleaned regularly using a rubber ball cleaning device. The rubber ball cleaning device is a key piece of equipment in the condenser system of thermal power plants for online cleaning of the inner walls of cooling pipes. Its working principle is to put qualified rubber balls into the cooling water pipes to rub and remove dirt from the inner walls of the pipes. The diameter of the qualified rubber balls should be slightly larger than the inner diameter of the cooling pipes. Under the action of the circulating water pressure difference, the rubber balls are squeezed and deformed and enter the cooling water pipes. Through friction, the inner walls of the cooling pipes are cleaned, improving heat exchange efficiency and ensuring the safe and economical operation of the unit.

[0003] After repeated use for a long time, some of the rubber balls become unqualified due to wear and collision. The unqualified rubber balls need to be picked out manually, which is tedious and time-consuming. As for the qualified rubber balls, since there are no effective sorting tools, hundreds or thousands of rubber balls can only be judged by visual inspection and manually picked out. This is not only time-consuming and laborious, but also prone to inaccurate judgment. Often, the unqualified rubber balls are used for a long time, which affects the cleaning effect on the condenser. Utility Model Content

[0004] To address the time-consuming and labor-intensive problem of selecting substandard condenser balls, this application provides a condenser ball sorting device.

[0005] In a first aspect, this application provides a condenser ball separator, which adopts the following technical solution:

[0006] A condenser ball screener includes a platform that is gradually inclined upward from the side closest to the ground to the side furthest from the ground. The platform is provided with a plurality of sieve holes spaced apart for screening unqualified balls. The diameter of the sieve holes is smaller than the diameter of qualified balls. The platform is surrounded by barriers on all four sides. The barriers include baffles located on the side of the platform closest to the ground. The baffles are detachably installed on the platform.

[0007] By adopting the above technical solution, when it is necessary to screen out unqualified rubber balls after long-term use, the rubber balls are poured into the side of the platform away from the ground, so that the rubber balls roll down the slope of the platform. Unqualified rubber balls fall through the sieve holes because their diameter is too small, while qualified rubber balls roll to the baffle, thereby quickly screening out the unqualified rubber balls.

[0008] Optionally, two mounting strips are fixed on the side of the enclosure near the baffle. The mounting strips are perpendicular to the platform and spaced apart at the two end corners of the platform. Limiting grooves are formed through the sides of the mounting strips that are close to each other. The two parallel sides of the baffle are respectively inserted into the limiting grooves, so that the baffle is perpendicular to the platform.

[0009] By adopting the above technical solution, when a qualified rubber ball rolls to the side near the baffle, the baffle can be pulled out vertically to make the rubber ball slide off the platform, which facilitates the collection of qualified rubber balls.

[0010] Optionally, the sieve holes are evenly distributed in an array along the length of the platform, and multiple partitions are fixed at intervals on the platform. The length of the partitions is parallel to the tilt direction of the platform, and the sieve holes are located between two adjacent partitions.

[0011] By adopting the above technical solution, the screening effect of the rubber balls is further improved by setting up baffles, and the rolling process of the rubber balls is guided so that the rubber balls can be screened through the sieve holes.

[0012] Optionally, each of the sieve holes is fixed with a cylinder to receive unqualified rubber balls. The upper end of the cylinder is fixedly connected to the platform and is connected through the sieve hole. The end of the cylinder away from the platform is threadedly connected with a threaded cap.

[0013] By adopting the above technical solution, when unqualified rubber balls fall from the sieve holes, they will enter the cylinder, which collects the unqualified rubber balls, and the unqualified rubber balls can be discharged by removing the threaded cap.

[0014] Optionally, it also includes an adjustment mechanism for extending the rolling distance of the rubber ball on the platform. The adjustment mechanism includes supports fixed on both sides of the platform, with the middle sections of both sides of the platform rotatably connected to the upper ends of the supports. The adjustment mechanism also includes an adjustment component for adjusting the tilt angle of the platform.

[0015] Optionally, the adjustment assembly includes a motor fixed to one side of the platform, a rotating roller fixed to the output end of the motor, mounting seats installed at both ends of the rotating roller, the rotating roller being rotatably connected to the platform through the mounting seats, a telescopic rope wound around the rotating roller, a fixing block fixed below the platform, and the end of the telescopic rope away from the rotating roller being fixedly connected to the fixing block.

[0016] By adopting the above technical solution, the telescopic rope can be extended and retracted by rotating the motor in the forward or reverse direction, thereby enabling the platform to rotate around the pivot, changing the tilt direction of the platform, increasing the rolling distance of the rubber balls on the platform, and improving the screening effect of the rubber balls.

[0017] Optionally, a counterweight is also fixed to the bottom wall of the platform at the end away from the motor.

[0018] By adopting the above technical solution, the counterweight ensures that the telescopic rope can always remain taut.

[0019] Optionally, each of the support sidewalls is also fixed with a support rod, which extends toward the platform. When the platform is tilted so that the rubber ball slides toward the baffle, the support rod abuts against the bottom of the platform.

[0020] By adopting the above technical solution, when the support rod abuts against the platform and supports the platform, it is convenient for the rubber balls on the platform to be discharged.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. When it is necessary to screen out unqualified rubber balls after long-term use, pour the rubber balls onto the side of the platform away from the ground, so that the rubber balls roll down the slope of the platform. Unqualified rubber balls, due to their small diameter, fall through the sieve holes, while qualified rubber balls roll to the baffle, thus quickly screening out the unqualified rubber balls.

[0023] 2. When a qualified rubber ball rolls to the side near the baffle, the baffle can be pulled out vertically to make the rubber ball slide off the platform, making it easy to collect the qualified rubber balls.

[0024] 3. By rotating the motor in the forward or reverse direction, the telescopic rope can be extended or retracted, which in turn allows the platform to rotate around the pivot, changing the platform's tilt direction and increasing the rolling distance of the rubber balls on the platform, thus improving the screening effect of the rubber balls.

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0030] This application discloses a condenser ball sorter.

[0031] Reference Figure 1 and Figure 2 A condenser ball screener includes an adjustment mechanism 1 and a platform 2 mounted on the adjustment mechanism 1. The adjustment mechanism 1 includes two supports 11 fixed to the ground. The platform 2 is horizontally inclined between the two supports 11, with the supports 11 located in the middle of the platform 2 and rotatably connected to the side wall of the platform 2. This allows the platform 2 to gradually tilt upwards from the side closer to the ground to the side farther away from the ground, and the platform 2 can rotate vertically. Support rods 12 are fixed to the supports 11 to provide inclined support for the bottom of the platform 2, ensuring the platform 2 can be stably inclined on the supports 11. The platform 2 is used to receive the balls to be screened. Barriers 21 are vertically fixed to all four sides of the platform 2 to reduce the chance of balls falling from the platform 2 to the ground. The platform 2 has multiple evenly spaced sieve holes 22, the diameter of which is smaller than the diameter of a qualified ball, allowing unqualified balls whose diameter has decreased due to wear to enter the sieve holes 22. When screening out unqualified rubber balls, pour the rubber balls onto the higher side of platform 2, so that the rubber balls roll down the slope of platform 2. Qualified rubber balls roll to the lower side of platform 2, and unqualified rubber balls fall into the sieve holes 22.

[0032] A cylinder 23 is fixed through each sieve hole 22. The cylinder 23 is vertically fixed to the lower surface of the platform 2. The lower end of the cylinder 23 is threadedly connected to a threaded cap 231. Unqualified rubber balls will automatically enter the cylinder 23 and be temporarily stored in the cylinder 23. When the unqualified rubber balls accumulate to a certain amount, the unqualified rubber balls collected in the cylinder 23 will fall out by rotating the threaded cap 231, which will facilitate subsequent processing.

[0033] The upper surface of platform 2 is also vertically fixed with multiple spaced and parallel partitions 24. The length direction of the partitions 24 is parallel to the length direction of platform 2, and there are sieve holes 22 between two adjacent partitions 24. The partitions 24 play a guiding role in the tilting and sliding of the rubber balls.

[0034] Reference Figure 2 and Figure 3The enclosure 21 on the side of platform 2 closest to the ground includes a detachable baffle 211. Two mounting strips 212 are fixed on the side of the enclosure 21 closest to the baffle 211. The mounting strips 212 are perpendicular to platform 2 and are positioned opposite each other on both sides of the baffle 211. Limiting grooves 213 are provided on the side of the two mounting strips 212 closest to each other. The two parallel sides of the baffle 211 are inserted into the limiting grooves 213 respectively, so that the baffle 211 will not detach from the upper surface of platform 2 in the horizontal direction. When the baffle 211 is in the limiting groove 213, it blocks the rubber balls on platform 2. When the baffle 211 is pulled out vertically from the limiting groove 213, the rubber balls can slide down the slope of platform 2, so that qualified rubber balls fall off platform 2, which is convenient for subsequent collection of qualified rubber balls.

[0035] Reference Figure 1 The adjustment mechanism 1 also includes an adjustment component 13 for tilting the platform 2. The adjustment component 13 includes a motor 131 fixed to one end of the platform 2. The motor 131 is located on the side of the platform 2 away from the baffle 211. A rotating roller 132 is coaxially fixed to the output end of the motor 131. A mounting base 133 for mounting the rotating roller 132 is also fixed on the platform 2, allowing the rotating roller 132 to be rotatably mounted on the mounting base 133. A telescopic rope 134 is wound around the outside of the rotating roller 132. The forward or reverse rotation of the output shaft of the motor 131 can realize the extension and retraction of the telescopic rope 134. A fixing block 135 is fixed to the bottom of the platform 2. The fixing block 135 is fixed to the ground. The telescopic rope 134 extends away from the rotating roller 132 and is fixedly connected to the fixing block 135. A counterweight 136 is fixed to the end of the platform 2 away from the motor 131 to further ensure that the telescopic rope 134 can remain taut. When the extended length of the telescopic rope 134 becomes shorter, the platform 2 gradually tilts upward from the side closer to the fixed block 135 to the side farther away from the fixed block 135. When the extended length of the telescopic rope 134 becomes longer, the platform 2 gradually tilts downward from the side closer to the fixed block 135 to the side farther away from the fixed block 135, so that the rubber balls on the platform 2 can roll back and forth, improving the screening effect of the rubber balls.

[0036] The implementation principle of the condenser ball screener in this application embodiment is as follows: When it is necessary to screen unqualified balls, the balls are poured onto the platform 2, and then the motor 131 is started to retract the telescopic rope 134, thereby realizing the vertical rotation of the platform 2 on the support 11, and thus realizing the reciprocating rolling of the balls on the platform 2. Unqualified balls, due to their small diameter, enter the sieve hole 22 and are collected by the cylinder 23. Qualified balls are finally removed by disassembling the baffle 211, allowing the qualified balls to slide out of the platform 2 from the baffle 211 for convenient subsequent collection and use.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
