Description

Trash device

Technical Field

The invention relates to the technical field of trash holding and cleaning, in particular to a trash holding device.

Background

The most important component of the trash holding device is a trash rack, which is generally a frame-grid structure disposed in front of the water inlet for holding water plants and other trash (generally called as trash) carried by the water flow. The garbage blocking device is applied to a circulating water system of a thermal power plant, wherein the frame grid type structure is arranged in the circulating water inlet flow channel and used for intercepting hard particulate matters and flexible garbage entering an inlet of a circulating water pump, so that no solid particulate matters in circulating water enter the circulating water pump, the circulating water inlet flow channel is prevented from being blocked by the garbage, and the normal operation of the circulating water system of the thermal power plant is met.

The original common trash rack can cause the garbage intercepted in front of the trash rack to be flushed into water again to enter the circulating water pump due to the flushing of water flow in the hoisting process. Some circulating water systems are provided with secondary filter screens, but the secondary filter screens have the problems that hydraulic resistance in a pipeline system of an outlet of a circulating water pump is obviously increased, circulating water flow is obviously reduced, circulating pump current is increased, and circulating water flow entering a condenser is reduced. The pressure difference is regulated to be 4.9-6.9 kpa by secondary filter screen specification, the actual operation is very high, the pressure difference of some unit secondary filter screens is more than 20kpa for a long time, the cleaning is troublesome, and the labor intensity of workers is high.

At present, the method for cleaning the trash rack mainly comprises manual trash cleaning and mechanical trash cleaning, wherein manual trash cleaning is carried out manually, and mechanical trash cleaning is carried out by a mechanical trash cleaning machine generally. However, both often have the following problems in their work: although manual dirt removal is thorough, the work is extremely heavy, the efficiency is low, the potential safety hazard of a human body exists, and in order to thoroughly remove impurities, a mode of lifting a grid to remove dirt after a circulating pump stops running is needed, so that the normal running of a unit is influenced; the mechanical sewage disposal has various types of sewage disposal machines, but the problems of incomplete sewage disposal exist.

In summary, how to effectively solve the problems of time and labor waste, incomplete cleaning and the like in trash rack cleaning is a problem which needs to be solved urgently by a person skilled in the art at present.
