Abstract
Disclosed is a back washing water refiltration device for a refrigerated water filter, belonging to the water purification technical field and aiming to solve the problem in recycle of purified water. The utility model adopts the technical proposal that the back washing water refiltration device comprises a filter shell, a water intake chamber, a water outlet chamber and a filtration chamber; the filter shell consists of an upper conical part and a lower columnar part; the water intake chamber is located at the conical part of the shell, the water outlet chamber is located at the upper part of the columnar part of the shell, and the filtration chamber is located between the water intake chamber and the water outlet chamber; an upper baffle, a filtration layer and a lower baffle are sequentially arranged in the filtration chamber from top to bottom; and eyelets are evenly distributed on the upper baffle and the lower baffle. The back washing water refiltration device is connected in a water circulation system of an air conditioner to guide out the recycled water to be purified for the second time, so that the recycled water can be used as back washing water for a reflection tube of the filter. The back washing water refiltration device enables the softened water in the water circulation system to be used fully and the reflection tube can not be jammed due to scale or poor quality of the water, thus reducing the maintenance work amount of the equipment and at the same time ensuring the quality of the water of the water circulation system of the air conditioner.
Description
Technical field
The utility model relates to the water purification treating apparatus, and particularly textile industry chilled water filter backwash water refilters device, belongs to water purification treatment technology field.
Background technology
For a long time, mostly textile enterprise's air conditioner water filter reflection tube backwash water is directly to utilize circulating pump delivery port water supply the carrying out backwash of the air conditioner water circulatory system, utilize recirculated water to carry out the backwash of filter reflection tube, have following problems: the water of returning from the air conditioning chamber contains a large amount of fibers and dust, through recycling once more behind the rotation water filter filtration backwater, in order to guarantee water amount, the water filter screen pack is generally the following stainless (steel) wire of 40 orders, filter effect is relatively poor, still contain more impurity in the water, and the backwash tube eye diameter of rotation water filter is less, these impurity are easy to block the aperture on the reflection tube in backwash process, cause the flushing of water filter filter screen unclean, influence the water filtration effect.In addition, if adopt the running water backwash obviously can cause the waste of water resource.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of and solves that backwash water refilters problem, chilled water filter backwash water simple in structure, easy operating refilters device
The alleged problem of the utility model solves with following technical proposals:
A kind of chilled water filter backwash water refilters device, its special feature is: comprise filter housings, intake chamber, water-supplying chamber and filter chamber in the formation, described filter housings is made up of lower cone part and top column part, described intake chamber is positioned at the housing tapered segment, water-supplying chamber is positioned at housing column part top, the filter chamber is between intake chamber and water-supplying chamber, and the filter chamber is by being provided with overhead gage, filter course, lower baffle under last successively, uniform eyelet on the upper and lower baffle plate.
Above-mentioned chilled water filter backwash water refilters device, and described filter course is a quartz sand, and the eye diameter of described overhead gage, lower baffle is 4～6 millimeters.
Above-mentioned chilled water filter backwash water refilters device, and described intake chamber is provided with water inlet pipe, and water-supplying chamber is provided with outlet pipe, is provided with blow-off pipe in the water-supplying chamber bottom.
The utility model improves as the problem that filter reflection tube backwash water easily stops up reflection tube at the recirculated water that uses the air conditioner water circulatory system, specialized designs a kind of device that air conditioner water circulatory system recirculated water is refiltered.This device inserts in the air conditioner water circulatory system, and recirculated water is drawn, and carries out being used further to filter reflection tube backwash water after secondary filter purifies through described device.Adopt the utility model that the demineralized water in the water circulation system is fully used, reflection tube can not stop up because of water quality inferiority or fouling again, reduce the m of e workload, saved the running water consumption, guaranteed air conditioner water circulatory system water quality requirement simultaneously.The utility model is simple in structure, be easy to realize, good filtration effect, except that textile industry, also can be used in the water purification filter system of other association area.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label is expressed as follows in the accompanying drawing: 1. filter housings; 2. water-supplying chamber; 3. outlet pipe; 4. go up plate washer, 5. the filter chamber; 5-1. filter course; 6. lower baffle plate; 7. intake chamber; 8. water inlet pipe; 9. blow-off pipe.
The specific embodiment
Referring to Fig. 1, during constituting, the utility model comprises the filter housings 1 of upper prop inferior pyramidal shape, be provided with intake chamber 7, water-supplying chamber 2 and filter chamber 5 in the filter housings.Intake chamber is positioned at the tapered segment of lower housing portion, and intake chamber is provided with water inlet pipe 8, is provided with blow-off pipe 9 in intake chamber tapered segment bottom; Water-supplying chamber is positioned at housing column part top, and water-supplying chamber is provided with outlet pipe 3; The filter chamber is between intake chamber and water-supplying chamber, and the filter chamber is by being provided with overhead gage 4, filter course 5-1, lower baffle 6 successively under last, and uniform eyelet on the upper and lower baffle plate, eye diameter are 4～6 millimeters, and filter course adopts quartz sand.
When the utility model uses, it is inserted the water circulation system of refrigeration plant, recirculated water enters intake chamber by water inlet pipe, see through lower baffle plate and enter filter course, discharge the purifying waste water of discharge as filter reflection tube backwash water by the outlet pipe of water-supplying chamber through seeing through last plate washer behind the impurity dirt of filtering layer filtration, purification place to go again.During use, regularly open the blow-off pipe valve and discharge the dirt that accumulates in the intake chamber bottom, to guarantee clean water quality.
