Description

Novel ball collecting device

Technical Field

The utility model belongs to the technical field of the rubber ball washs, specifically a novel receive ball ware.

Background

The rubber ball cleaning system is a widely applied device for cleaning condenser cooling pipes in the working process on line by using rubber balls. The ball collector is one of indispensable devices of a cleaning system. The structure of the interior of the ball collecting device is improved on the basis of the rubber ball cleaning system independently researched and developed by our company, the ball collecting rate and the pollution discharge capacity of the system are greatly improved, the safety of the system is improved, and the rubber ball cleaning system is further improved.

The ball collecting rate is one of important indexes for measuring the cleaning degree of the condenser pipe, and the quality of the ball collecting rate is directly related to the action of a rubber ball cleaning system. At present, a rubber ball cleaning system developed by our company is superior to rubber ball cleaning systems of most other companies in ball collection rate on the aspects of mechanical structure, electrical control and the like, and is well proved in practical application cases of various thermal power plants, cement plants and the like.

However, when the impurities in the circulating water of the condenser are complicated and the impurities are numerous, the impurities are mixed with the rubber balls and attached to the net surface of the ball collecting net, and the steel wire brush of the ball collecting device cannot smoothly clean the rubber balls from the ball collecting net due to the blocking effect of the impurities, so that the ball collecting quantity is reduced, and the ball collecting rate is reduced. In addition, when the pressure difference between the cooling water inside and outside the ball receiving net is too high, the rubber balls can be firmly attached to the meshes of the ball receiving net due to the action of the water pressure, and the purpose that the steel wire brush cannot effectively clean the rubber balls can be caused.
