Crank connecting rod type ball net drawing device

Abstract

This invention relates to a winch connection lever collection net, which comprises the ball collection cylinder, net plate, net plate rotation axis, rubber ball draw-off pipe, flow guiding plate, driving and executive devices and operation devices. The axis is located on the cylinder and the net plate down part is located with a swing rack. The executive device is the winch connection lever structure and the rotation rack and the executive device connection lever are hinged with one end connected to the winch lever. The driving device winch axis is connected to the operation device outside the ball collection cylinder with its winch located on the axis of the cylinder.

Description

technical field [0001] The invention relates to a crank-and-rod ball collecting net device for continuously cleaning condensers with rubber balls, which is used for recycling rubber balls for continuous cleaning of cooling water pipes of condensers of thermal power or nuclear power units and various surface heat exchangers. Background technique [0002] It is an effective method commonly used in thermal power units to continuously and automatically clean the pollution of the cooling water pipe of the condenser with a single rubber ball. For the rubber ball cleaning device that can be put into use, only normal operation and maintenance are required to reduce the end difference of the condenser. The purpose of improving vacuum, saving fuel and increasing efficiency. [0003] The key device in the rubber ball cleaning system is the ball collecting net device, which has been improved many times so far. The patent No. ZL01268792.8 designed by the applicant is that the ball collec...

Problems solved by technology

But the crank-link mechanism in this net receiving device is assembly type, has two crank axle shafts in its structure, is equipped with respectively crank respectively, is provided with common crank in the middle and is connected to two crank separately by crank pin Together, in this way, concentric installation is required, resulting in very high machining accuracy and assembly accuracy, which increases the difficulty and cost of production. In the assembly process, repeated disassembly and assembly and multiple adjustments are required to meet the requirements. The installation operation is troublesome, and assembly The rigidity and strength of the conventional structure are poor, and it is difficult to guarantee the function and quality
