Filtering equipment capable of automatically cleaning middle-deep layer geothermal system and convenient to disassemble

Abstract

The invention belongs to the technical field of pipeline cleaning, and discloses filtering equipment capable of automatically cleaning a medium-deep layer geothermal system and convenient to disassemble. The upper end of a cylinder is blocked by a flange cover plate, the middle of the left side of the cylinder is communicated with a water inlet, the upper end of the right side of the cylinder is communicated with a water outlet, a stainless steel filter screen is detachably arranged in the cylinder, the upper end of the stainless steel filter screen inclines towards the water inlet, and the lower end inclines towards the water outlet; and a dirt isolation plate is arranged at the lower end in the cylinder, the upper end of the dirt isolation plate abuts against the middle of the right side of the stainless steel filter screen, a sewage draining outlet is formed in the lower end of the left side of the cylinder, filter screen clamping grooves are obliquely formed in the inner wall of the cylinder, and the two ends of the stainless steel filter screen are clamped in the filter screen clamping grooves. The equipment can be automatically flushed, dirt is convenient to clean, and the system can be cleaned at any time under the condition that normal operation of system equipment is not influenced; the product specification and the filtering grade can be flexibly customized according to requirements; the filtering area is large, the water passing amount is sufficient, and filth blockage is not easy to form; and floaters in the sewage are not easy to attach to the filter screen to form filth blockage.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning, and in particular relates to automatic cleaning and convenient disassembly filtering equipment for a middle-deep geothermal system. Background technique [0002] At present: Since the project adopts a sewage source heat pump system, the water quality of the sewage water source is poor, and the system uses cyclone desander, backwash filter, Y-type filter and other common filtration equipment in the market, all of which will be due to the small filtration area and insufficient water flow. Rapid dirty blockage occurs, the host is protected, and the system cannot work normally at all. Moreover, the cleaning process with the above equipment is cumbersome and the cleaning time is long, which cannot guarantee the continuous and stable operation of the system. [0003] Through the above analysis, the problems and defects of the existing technology are: the existing water system filtration prod...

AI Technical Summary

Problems solved by technology

[0002] At present: because the project adopts a sewage source heat pump system, the water quality of the sewage water source is poor, and the system uses cyclone desander, backwash filter, Y-type filter and other common filtration equipment in the market, all of which are due to the small filtration area and insufficient water flow. In the event of rapid dirty blockage, host protection, and the system cannot work normally at all

Moreover, the cleaning process with the above equipment is cumbersome and the cleaning time is long, which cannot guarantee the continuous and stable operation of the system

[0003] Through the above analysis, the problems and defects of the existing technology are: the existing water system filtration products in the market will exist in the application of the sewage source heat pump system and other harsh water environment systems: the filtration area is small, the floating objects are difficult to clean, and the filtration equipment It is easy to be dirty and blocked, causing the protection of downstream equipment such as the main engine to fail to work normally; or the existing water system products in the market have a significant effect on sediment filtration and are easy to clean, but cannot overcome dirty and clogged floating objects

The cleaning process is cumbersome and the cleaning time is long, which cannot guarantee the continuous and stable operation of the system
