Description

Technical Field

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

[0002] The background technology behind condenser rubber ball cleaning machines stems from the maintenance needs of condensers in thermal power plants. Traditional cleaning technologies include both stop-and-go cleaning and non-stop online cleaning. Rubber ball cleaning, a non-stop online cleaning technique, is widely used. Rubber ball cleaning involves injecting rubber balls into the condenser. These balls enter the heat exchange tubes from the lower chamber, where they rub against the tube walls to remove dirt. The balls then exit from the upper chamber for subsequent recovery.

[0003] When the existing condenser is cleaned with rubber balls, when the cleaning liquid enters the lower chamber, eddy currents are easily generated, causing the rubber balls to accumulate there. In addition, there is a certain dead zone in the lower chamber, which is not conducive to the dispersion of the rubber balls into each heat exchange tube, resulting in incomplete cleaning, thereby reducing the working efficiency of the condenser due to the influence of dirt. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: when the existing condenser is cleaned with rubber balls, when the cleaning liquid enters the lower chamber, eddy currents are easily generated, causing the rubber balls to accumulate here, and there is a certain dead zone in the lower chamber, which is not conducive to the dispersion of the rubber balls into each heat exchange tube, resulting in incomplete cleaning, thereby reducing the working efficiency of the condenser due to the influence of dirt. A dual-flow surface condenser rubber ball cleaning system is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The condenser tube of the present invention is a kind of double-flow surface type condenser rubber ball cleaning system, comprising a condenser body, wherein a plurality of heat exchange tubes are fixedly embedded in the condenser body, and end covers are fixedly connected to the end covers at both ends by flanges. A ball cavity is opened in the two end covers, and a partition plate is fixedly installed on the inner wall of the end cover on the right side. The partition plate divides the ball cavity into an upper cavity and a lower cavity. A return pipe and an inlet pipe are fixedly installed on the surface of the end cover on the right side. The interior of the return pipe is connected with the upper cavity, and the interior of the inlet pipe is connected with the lower cavity. The upper cavity is provided with a propeller, and a rotating rod is provided in the return pipe, one end of the rotating rod is fixedly connected to the propeller, and the other end is connected to a ball receiving component, the rotating rod is provided with a partial reciprocating thread, and a movable sleeve is sleeved on the thread, and the movable sleeve is connected to a pressure rod through a sliding sealing component, the pressure rod is located in the inlet pipe, and is rotatably sleeved with a guide plate, and the guide plate is rotatably connected to the partition plate through a rotating shaft.

[0007] Preferably, the ball collecting component includes a rotating block fixedly sleeved on one end of the rotating rod, and a ball collecting net is fixedly installed on the inner wall of the return pipe, and the surface of the ball collecting net is in sliding contact with the rotating block.

[0008] Preferably, the sliding sealing component includes a sliding rod, and sliding grooves are provided on the lower surface of the return pipe and the upper surface of the inlet pipe. One end of the sliding rod is fixedly connected to the movable sleeve, and the other end is fixedly connected to the pressure rod. Two sealing strips are fixedly sleeved on the sliding rod, and the two sealing strips are in sliding sealing contact with the inner walls of the return pipe and the inlet pipe respectively.

[0009] Preferably, the return pipe is fixedly connected to the ball-distributing component via the ball-receiving pipe, and the inlet pipe is fixedly connected to the ball-distributing component via the ball-distributing pipe.

[0010] Preferably, the ball-serving component includes a ball-serving device, and a water pump is fixedly mounted on the upper surface of the ball-serving device.

[0011] Preferably, a ball placing port and a ball taking port are provided on the surface of the ball launcher, the ball placing port and the ball receiving tube are located at the same horizontal plane, and the ball taking port and the ball launching tube are located at the same horizontal plane.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the cleaning liquid flows through the propeller, it will rotate, and then cooperate with the rotating rod, the movable sleeve sliding rod and the pressure rod to push and pull the guide plate back and forth to rotate axially around the rotating axis, thereby destroying the vortex zone in the lower chamber. When the guide plate gradually turns upward, the rubber ball can be pushed from top to bottom into each heat exchange tube, avoiding the dead zone in the lower half, so that the rubber ball evenly enters each heat exchange tube for cleaning, thereby improving the cleaning efficiency and enhancing the cleaning effect.

[0014] When the rotating rod rotates, it drives the rotating block to rotate together, thereby pushing the rubber balls left on the surface of the ball collecting net into the ball collecting tube, thereby improving the ball collection rate of the rubber ball cleaning system.
