Description

Technical Field

[0001] This utility model belongs to the field of ball-collecting net technology, and specifically relates to an anti-clogging conical ball-collecting net with online self-cleaning function. Background Technology

[0002] In current industrial applications, rubber ball cleaning devices are widely used to clean various surfaces, especially in generator sets, to clean the fouling inside the condenser to improve heat exchange efficiency. These devices typically include a conical (funnel-shaped) ball collecting net to recover the rubber balls after cleaning.

[0003] However, existing ball cleaning devices have several significant drawbacks. First, they often fail to effectively recover balls when water quality is poor or the circulating water flow rate is abnormal (too high or too low). In such cases, the balls may be trapped in the ball-collecting net instead of being properly recovered, thus affecting cleaning efficiency. Second, existing ball-collecting nets lack online self-cleaning capabilities, meaning that manual cleaning is required when the net is heavily soiled. This not only reduces operational efficiency but may also lead to unplanned generator shutdowns in emergencies. Furthermore, due to the large contact area between the conical ball-collecting net and the circulating water, vortices are easily generated at the bottom ball outlet, causing poor ball discharge, especially when a large number of balls are being recovered simultaneously, making blockages more likely.

[0004] To address these issues, some existing patent documents attempt to alleviate blockage by partially opening the mesh plate. However, these methods do not fundamentally solve the problem and may be ineffective in some cases, leading to severe blockage, cracking, or deformation of the mesh plate, which in turn affects the normal operation of the entire device.

[0005] Therefore, there is an urgent need for a clog-resistant conical ball catcher with online self-cleaning function, which can realize online self-cleaning, automatic sewage discharge, anti-clogging of the ball outlet, and anti-jamming of the transmission assembly, so as to improve cleaning efficiency, reduce manual intervention, and ensure stable operation of the device under complex working conditions.

[0079] When the mesh holes of the mesh plate 2 are seriously blocked, the motor two 72 is started, the output shaft of the motor two 72 rotates to drive the left and right helical screw 7 to rotate, when the left and right helical screw 7 rotates, the sliding block 70 moves, when the sliding block 70 moves, the connecting rod 20 moves, and then the mesh plate 2 moves, the distance between the two mesh plates 2 is generated, and the sundries on the mesh plate 2 are washed away under the impact force of the water flow, thereby improving the cleaning efficiency and reducing the decline in cleaning efficiency caused by the blockage of the mesh holes. Not only improves the convenience of use, but also reduces the need for manual intervention, improves the automation level of the equipment;

[0080] When the motor one 71 works, the output shaft of the motor one 71 rotates to drive the bevel gear one 62 to rotate, when the bevel gear one 62 rotates, the bevel gear two 63 rotates, when the bevel gear two 63 rotates, the rotatable drain pipe 4 rotates, when the rotatable drain pipe 4 rotates, the trapezoidal drain scraper 40 rotates, the rubber scraper connected with the trapezoidal drain scraper 40 cleans the mesh plate 2, the L-shaped drain pipe 42 is connected with the cleaning pump or the rubber ball pump, under the action of negative pressure and the cleaning pump or the rubber ball pump, the sundries on the mesh plate 2 are removed through the rotatable drain pipe 42 and the L-shaped drain pipe 42;

[0081] When the rotatable drain pipe 4 rotates, the anti-blocking spoiler 50 rotates to disturb the water flow in the ball outlet chamber 8, preventing the rubber ball or sundries from accumulating and blocking the inner cavity of the ball outlet chamber 8. The rubber ball outlet pipe 51 is a 120° elbow pipe, which prevents the pressure loss of the traditional right-angle elbow pipe from causing the rubber ball flowing through the ball outlet chamber 8 to accumulate and block.
