Abstract

The utility model discloses a sand removing filter for water supply well for purifying water, which can be effectively used for the water supply well to solve the problem of sand removing during the flow rate of feeding water changing; the lower side of the barrel is provided with a sand removing pipe outlet and a well water pipe inlet, the upper part of the barrel is provided with a pure water outlet pipe, the pure water outlet pipe is communicated with a gravel filtering pipe in the barrel through a flange by a bend, and the pipe wall of the gravel filtering pipe is provided with a bridge water inlet. The utility model has the advantages of novel structure, easy use and installation, simple operation, long service life, no need of backwashing, uneasy blockage of the filter bed, small pressure loss, influence-free from the water quantity, flow rate and sand size, safety and reliability, wide appliance, great foreground, and improved economical and social benefits.

Description

Water supply well removes sand filter

One, technical field

The water supply well that the utility model relates to a kind of usefulness of purifying waste water removes sand filter.

Two, background technology

Water is basis and the lifeblood that the mankind depend on for existence.Totally whether the quality of its water quality, is directly connected to human life, production and development.Since whole world population increase in recent years, the industry great development, the variation of global climate, freshwater resources are shortage more and more, for this reason, global people are being raised a cry of warning for the sustainable development of water resource, seek countermeasure, the exploitation of water resource, particularly phreatic exploitation is paid close attention to by people always.Underground water is generally at the 4th tight unconsolidated formation Cheng Jing, exist the higher problem of sand content in various degree, in order to satisfy people's needs, often to purify desanding again, and hydrocyclone is generally adopted in water supply well desanding at present or filter desander, owing to structural reason, its result of use is also unsatisfactory, with the hydrocyclone is example, it is by cylinder, cone, the desanding tube, water inlet pipe, formations such as outlet pipe, when work, contain sand and the water two-phase fluid tangentially enters in the cylinder by water inlet pipe, along the inwall gyration, because the density of sand is greater than water, thereby under the inwall of action of centrifugal force lower edge, slide in the desanding jar of desander bottom, discharge by valve, in addition, because the high speed rotary motion of fluid makes the center of cyclone form a low-pressure area, water then enters water system by top fluid flow tube (outlet pipe), and at present, the supply equipment of general well adopts the frequency conversion automatic water-supply more, promptly regulates the flow velocity and the water yield of water pump automatically according to the water consumption size, like this, its water intake velocity is a variable, and the water inlet caliber also must be along with variation, so, when the water inlet change in flow, because centrifugal force is variable, hydrocyclone then can not reach the desanding purpose, does not satisfy in people's life and the production actual needs to water, therefore, the innovation of desander is imperative.

Three, utility model content

At above-mentioned situation, the purpose of the utility model just provides a kind of novel water supply well and removes sand filter, can be effective to water supply well, desanding problem when intaking change in flow to solve, the technical scheme of its solution is, the cylindrical shell downside has the sediment outflow mouth of pipe and well water water inlet pipe mouth, and the water purification outlet pipe is arranged at cylindrical shell top, the water purification outlet pipe is connected with the gravel strainer that is contained in the tube through flange by elbow, the bridge-type inlet opening is arranged on the gravel strainer wall, the utility model novel structure uniqueness, easy to install, simple to operate, long service life does not need backwash, and filter course is difficult for stopping up, the pressure loss is little, be not subjected to the influence of the water yield and flow velocity and sand grains size, safe and reliable, widely applicable, DEVELOPMENT PROSPECT light has good economic and social benefit.

Four, description of drawings

Fig. 1 is a structural outer front view of the present utility model.

Fig. 2 is shell portion sectional front view of the present utility model (clipping top water purification outlet pipe).

Fig. 3 is a vertical view of the present utility model.

Fig. 4 cuts enlarged drawing open for gravel strainer structure partial of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Provide by Fig. 1, Fig. 2, Fig. 4, the utility model is that the sediment outflow mouth of pipe 2 and well water water inlet pipe mouth 3 are arranged at the bottom of cylindrical shell 1, water purification outlet pipe 6 is arranged at cylindrical shell 1 top, water purification outlet pipe 6 is connected with the gravel strainer that is contained in the cylindrical shell 1 by elbow 7 and flange 5, gravel strainer is to have bridge-type inlet opening 10 on the perisporium of water pipe 4, and the hole of bridge-type inlet opening 10 is encircleed 9 external seals and is pasted with gravel filter course 8.Bridge-type inlet opening 10 is meant that the inlet opening on water pipe 4 perisporiums is the bridge opening formula, and the inlet opening communicates with the two side holes of hole arch 9, because tube wall is rough and uneven in surface, the gravel filter course is firm, and the intensity height is difficult for breaking, and helps improving the filter sand effect.Cylindrical shell 1 is generally rounded, the quantity of the gravel strainer in its cylindrical shell 1 what, visual water yield what and different, present embodiment provides 4 pipes, can adorn a pipe for general 10 tons/hour, two in 20 tons/little fashionable dress, the rest may be inferred, but be equipped with one at least in the cylindrical shell; The gravel filter course can adopt quartzy gravel bed commonly used, also can adopt adhesive, curing agent, gravel material (quartz gravel) and ethanol to be mixed and made into, and is mounted on the pipe bridge opening part through dress mould, the demoulding, sturdy and durable, good filtration effect through practice, the utlity model has following obvious good effect:

(1) simple to operate in easy for installation, the running, in drawing water, only need the Open valve then can be about 30 seconds during sediment outflow solids in the container or sand grains emptying.

(2) long service life is filtered and be need not special backwash, and filter course is difficult for stopping up.

(3) pressure loss is little, and the general pressure loss is at 0.01-0.05MPa.

(4) compare with hydrocyclone, be not subjected to the influence of other factorses such as flow velocity and sand grains size, and safety and reliability.

(5) scope of application is extensive, can be used for any water supply well desanding, and can play the filtration of foreign material or other solids in fields such as industrial colling and sewage disposals.

The utility model is that creative contribution must be made and be benefited the society and the mankind to the innovation of existing water supply well desanding filter.
