Abstract

The invention discloses a crushing type blockage prevention device which relates to a blockage prevention device for a sewage heat exchange system and aims to solve the problems of incomplete filtration, miscellaneous clearing operation, big temperature difference loss of the water source and high operating cost in the prior art in the process of processing big-grain sundries contained in the sewage which enters the equipment such as heat exchange equipment. The crushing type blockage prevention device comprises a fixed outer cylinder, a rotary inner cylinder, a shell barrel, a driving device, a plurality of inner blades and equal number of outer blades. The rotary inner cylinder and the fixed outer cylinder are respectively arranged inside the shell barrel; the fixed outer cylinder is sleeved outside the rotary inner cylinder; the driving device is arranged on the upper end face of the shell barrel; the inner blades are distributed on the outer circumferential side face of the rotary inner cylinder; the outer blades which are equal in number with the inner blades and correspond with the inner blades one by one are distributed on the inner circumferential side face of the fixed cylinder; and the rotation direction of each inner blade which takes the shape of a right-handed spiral cylindrical plane is opposite to the rotation direction of the corresponding outer blade. The crushing type blockage prevention device is used for processing the big-grain sundries contained in the sewage which enters the heat exchange system.

Description

technical field [0001] The invention relates to an anti-clogging device for a sewage heat exchange system, in particular to a device for crushing and treating raw sewage entering heat exchange equipment and other equipment, and large particles of dirt in surface water sources. Background technique [0002] In industrial or energy systems, especially in energy systems that use urban raw sewage and surface water sources (river water, river water, lake water, sea water, etc.) Treatment will lead to blockage of heat exchange equipment, and even damage to important equipment such as heat pump units, which will affect the effective operation of the system. Anti-clogging treatment is carried out on the sewage before entering the heat exchange equipment. The common equipment has an anti-blocking machine (for example: the Chinese patent number is ZL200410043654.9, and the invention patent with a publication date of March 16, 2005 provides a kind of roller grid. The urban sewage hydr...
