Abstract

The utility model relates to a catch basin and collecting sump type sewage filtering water intake system, which comprises a filtering structure layer (1), a catch basin (2), and a collecting sump (3). The filtering structure layer (1) comprises reticular filtering material, a variety of profile steel and steel pipes, and other frameworks, which has the elementary filtering function, and granular and suspending noxious foreign bodies can be eliminated to prevent a pipeline, a valve, a sewage pump, a heat exchanger or a heat pump unit and other equipments from being blocking up. The passing-water area is mainly and directly related to the flow rate and the water intake quantity of the sewage in the pipe. The cross section of the catch basin can be semicircular, triangular, trapezoid, quadrate, rectangular, and other shapes. The collecting sump can be combined with the sewage inspection, the structure is simple and applicable, the manufacture and the installation are easy, the operation and the management are convenient, the elementary filtering requirements to the city sewage can be met, and thus the catch basin and collecting sump type sewage filtering water intake system is the essential equipment which applies the heat pump technology and the relative equipment to extract the low temperature heat energy contained in the city sewage, and used for an air conditioner which heats and supplies heat in winter and refrigerates in summer.

Description

Catch basin and sump formula sewage water filtration water intake system

Affiliated technical field

The utility model relates to a kind of catch basin and sump formula sewage intake system.

Background technology

Municipal sewage (sanitary sewage, production waste drainage, rainwater etc.), summer temp is more than 18-26 ℃, and winter temperature is more than 8-18 ℃, and pH value is generally 6-8, and the suspension foreign material are more.

The quantity of municipal sewage is very huge, and it is very wide to distribute around our production, life, dwelling environment, wherein contains very many low temperature heat energies, can extract recycling fully, should not discard in vain.

Using heat pump technical principle and relevant device thereof when the user needs heating winter, can extract the low temperature heat energy that reclaims wherein, and it can also be promoted temperature municipal sewage as low-temperature heat source, and conveying passes to the user and utilizes.When the user needs refrigeration air-conditioner summer, can discharge heat energy to it sewage as low-temperature water source (cooling water source) again, reach the purpose of refrigeration air-conditioner for the user.

Municipal sewage is a kind of utilizable water resource of preciousness, but, extracting and using in the process of municipal wastewater flow process, suspension that contains in the sewage and graininess foreign material are for harmful, easily cause the obstruction of pipeline, valve, water pump, heat transmission equipment or source pump equipment, source pump can not normally be moved.

At present, known equipment of fetching water from sewage does not generally have good preliminary filtering function.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of catch basin and sump formula sewage intake system with preliminary filtering function, can effectively remove graininess and suspension foreign material in the decontaminated water.

The technical scheme in the invention for solving the technical problem is: this water intake system mainly is made of catch basin, sump, filtration layer three parts.The cross section of catch basin can be semicircle, circular arc, triangle, square, trapezoidal, multiple shape such as rectangle.The filtration layer is installed above the catch basin, it mainly is by expanded metal lath, stainless steel cloth, Web materials such as nylon wire, single or multiple lift is formed, useful various shaped steel, the skeleton that steel pipe is made, each intensity of certain rigidity is arranged, has decay resistance, has good water permeability (crossing the water-based energy), its total discharge area population size, with the flow velocity and the sewage intake quantity of sewage in the pipe duct direct relation is arranged, because the swabbing action of foul water pump, sewage in sump and the catch basin is taken away, form vacuum state, sewage in the pipe duct penetrates filtration layer seepage flow and enters catch basin and sump, requiring sewage to seep water the flow velocity that penetrates filtration beds should be less than the flow velocity of sewage in the pipe duct, be filtered a layer blocking harmful foreign material in the sewage and be subjected to one by the strength of vacuum suction in the catch basin, also to be subjected to the impact strength that effluent flow rate produces in the pipe duct in addition, the absorption strength that harmful foreign material are subjected to should be less than the impact strength of sewage, can in time be impacted and take away by the sewage in the pipe duct, be unlikely resting on for a long time on the filtration layer, influence the water permeability and the sewage intake quantity of filtration beds.Catch basin can be installed in the bottom of sewage pipe duct, also can be installed on the sidewall of sewage pipe duct, and sump can also combine with the sewage manhole.

The beneficial effects of the utility model are: install and use catch basin and sump formula water intake system, can be in extraction and application sewage, sewage is effectively carried out preliminary filtration treatment, remove the graininess and the suspension foreign material that contain in the decontaminated water, prevent blocking pipe, valve, water pump, heat transmission equipment or source pump equipment, its simple in structure being suitable for has wide range of applications, make and install easily, use and management is convenient.
