Description

Technical Field

[0001] This utility model relates to a condenser ball cleaning system for power plants, specifically a high-efficiency ball counting device. Background Technology

[0002] In the production process of thermal power plants, the condenser ball cleaning system is an indispensable device to ensure the cleanliness of the condenser. However, in daily operation, the addition and counting of the condenser balls are all done manually, which results in large statistical errors and waste of labor. Assuming that it is operated once a day, with 300 condenser balls added at a time, each addition and counting of condenser balls takes more than 30 minutes, which greatly wastes labor resources.

[0003] To address this, patent application number 202320096889.2 discloses a rapid counting device for rubber balls, and patent application number 201410397977.1 discloses a condenser rubber ball recovery and counting device. However, because the rubber balls are soft and have a certain degree of stickiness when wet, they tend to stick together in the rubber ball storage hopper, making it difficult to count the balls smoothly, which has certain defects in use. Utility Model Content

[0004] In view of this, the present invention discloses a high-efficiency rubber ball counting device to solve the problem of the counting tube opening being blocked by the mutual adhesion between rubber balls when using the existing rubber ball counting device.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A high-efficiency rubber ball counting device includes a support frame and a rubber ball storage hopper fixed to the top of the support frame. A sorting disk is rotatably mounted at the bottom of the rubber ball storage hopper, and the sorting disk is connected to a drive motor fixed to the support frame. The edge of the sorting disk is also provided with multiple sorting ports for receiving rubber balls, and a rubber ball lowering hole is opened at the bottom of the rubber ball storage hopper corresponding to one of the sorting ports. An electric gate valve is also installed on the rubber ball lowering hole. A photoelectric sensor is installed next to the rubber ball lowering hole, and the photoelectric sensor is directly facing the rubber ball lowering hole. A ball receiving slide is also provided directly below the rubber ball lowering hole, and the ball receiving slide is fixedly connected to the support frame.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] This invention, in use, uses a sorting disc to agitate the rubber balls stored in the ball storage hopper. Whether the rubber balls are new or have been recycled and moistened, they are dispersed into the sorting holes under the centrifugal force of rotation. As the sorting disc rotates, they are propelled forward until they fall into the ball discharge hole and are discharged, thus completing the ball counting process. The entire process is simple and efficient, solving the problem of rubber balls easily sticking together in the hopper and failing to be discharged for counting without affecting the counting process.

[0012] The present invention will be further explained below with reference to the accompanying drawings.

[0013] like Figure 1-2 As shown, a high-efficiency rubber ball counting device includes a support 1 and a rubber ball storage hopper 2 fixed to the top of the support 1. A sorting disk 8 is rotatably arranged at the bottom of the rubber ball storage hopper 2, and the sorting disk 8 is connected to a drive motor 3 fixed on the support 1. The edge of the sorting disk 8 is also provided with multiple sorting ports 9 for receiving rubber balls, and a rubber ball lowering hole 7 is opened at the bottom of the rubber ball storage hopper 2 corresponding to the position of one of the sorting ports 9. An electric gate valve 6 is also installed on the rubber ball lowering hole 7. A photoelectric sensor 5 is installed next to the rubber ball lowering hole 7, and the photoelectric sensor 5 is directly facing the rubber ball lowering hole 7. A ball receiving slide 4 is also provided directly below the rubber ball lowering hole 7, and the ball receiving slide 4 is fixedly connected to the support 1.

[0014] The photoelectric sensor 5 is linked and controlled in conjunction with the drive motor 3 and the electric gate valve 6. Specifically, the linkage control can be achieved through a PLC control system or a DCS control system, both existing technologies.

[0015] The specific working process of this utility model is as follows:

[0016] First, close the electric gate valve 6, pour a number of rubber balls into the rubber ball storage hopper 2, and start the drive motor 3 to drive the sorting disk 8 to rotate. The rubber balls that are clustered in the rubber ball storage hopper 2 are dispersed to the edge and enter the sorting port 9 under the action of the centrifugal force of the rotation of the sorting disk 8. If there are any sticky rubber balls, they can also be broken up by the shear force when entering the sorting port 9. After the rubber balls smoothly enter the sorting port 9, they rotate forward with the sorting disk 8 until they are directly opposite the rubber ball lower ball hole 7 and the balls are discharged. Since the bottom of the rubber ball lower ball hole 7 is narrow and only one rubber ball is allowed to pass through, it can avoid multiple balls falling at the same time and the ball discharge speed being too fast, which would affect the counting. Open the electric gate valve 6. When the rubber ball falls into the ball receiving slide 4, it will block the photoelectric sensor 5, causing its photoelectric signal to change, completing one count. After the next ball falls and blocks it, the signal will change again, completing another count. This cycle continues until all the rubber balls have fallen. The number of rubber balls can be obtained by accumulating the number of signal changes by the host computer. In addition, if a specific number of rubber balls are required, the host computer can close the electric gate valve 6 and the drive motor 3 after obtaining the corresponding number of rubber balls to stop dispensing the balls.
