Description

Rolling type filter

Technical Field

The utility model relates to a chemical industry, electric power technology, municipal administration environmental protection sewage treatment, in particular to roll formula filter.

Background

At present, automatic online water sampling analysis often causes sampling difficulty and overlarge maintenance amount due to dirt of water quality in a pipeline. The problem generally exists in the fields of general chemical industry, electric power technology and municipal environmental protection sewage treatment in China in the aspect of monitoring the regeneration and discharge of sewage.

The regeneration of sewage and the monitoring sampling process of discharging are the process that a needs continuous sampling, and the accurate instrument of cooperation carries out the analysis of each multiple primitive, and in actual operation, the ordinary filter that sets up in the sample pipeline is often blockked up by a large amount of aquatic debris, and the unable measurement system that flows into monitoring instrument of sample water leads to the regeneration of sewage and discharges the process and pause, often need shut down to unpick and wash the ordinary filter that debris blockked up, resumes again. Such frequent failures consume a large amount of labor and cause a serious waste water regeneration energy loss and reduce the efficiency of waste water discharge treatment.

SUMMERY OF THE UTILITY MODEL

Not enough to current technique, the utility model provides a roll formula filter.

In order to realize the purpose, the utility model adopts the technical scheme that: the utility model provides a roll formula filter, includes rose box body and filter tank lid, the rose box this internally separate out clean water storehouse and dirt storehouse through the baffle, clean water storehouse and dirt storehouse upper end are equipped with the filter chamber that is used for filtering the blowdown, the filter chamber is separated with clean water storehouse through the filter screen that the slope set up and is formed, the filter tank lid is equipped with the water sample import with the filter chamber intercommunication, the rose box body be equipped with the filtration water sample export of clean water storehouse intercommunication and with the drain of dirt storehouse intercommunication, the filter chamber passes through the filtration pore and the clean water storehouse intercommunication of filter screen, the filter chamber has the filth escape orifice with dirt storehouse intercommunication, after the water sample gets into the filter chamber from the water sample import and filters the back through the filter screen, the clean water gets into clean water storehouse, filth in the water sample rolls to filth escape orifice to the dirt storehouse from the filter screen that the slope set.

The filter screen be semicircle cone structure, and the filter screen is less than the internal diameter of filth escape orifice near the one end internal diameter of water sample import.

The filter box cover and the filter box body are fixedly assembled through fastening bolts.

And a sealing gasket is arranged at the contact part between the filter box cover and the filter box body.

The utility model has the advantages that: the utility model provides a roll formula filter, traditional filter system need frequent work system wash the change, need a large amount of engineering expenditures that consume. This filter exempts from to wash, avoids blockking up, avoids the work system often to shut down, can practice thrift a large amount of maintenance costs, improves production efficiency, and this roll formula filter has solved the chemical industry, and electric power technology, in the municipal environmental protection sewage treatment field, the sample difficulty that sample analysis instrument often met in the regeneration of sewage and the emission, and need not system pressure, and it is very effective, convenient to the filtration water intaking of large capacity.

Detailed Description

As shown in fig. 1, a rolling filter comprises a filter box body 100 and a filter box cover 200, wherein the filter box body 100 is internally separated into a clean water bin 300 and a dirt bin 400 by a partition plate, the upper ends of the clean water bin 300 and the dirt bin 400 are provided with filter chambers 500 for filtering and discharging dirt, the filter chambers 500 are separated from the clean water bin 300 by obliquely arranged filter screens 600, the filter box cover 200 is provided with a water sample inlet 210 communicated with the filter chambers 500, the filter box body 100 is provided with a filtered water sample outlet 110 communicated with the clean water bin 300 and a dirt discharge outlet 120 communicated with the dirt bin 400, the filter chambers 500 are communicated with the clean water bin 300 through filter holes of the filter screens 600, the filter chambers 500 are provided with a dirt discharge port 510 communicated with the dirt bin 400, when a water sample enters the filter chambers 500 from the water sample inlet 210 and is filtered by the filter screens 600, clean water enters the clean water bin 300, dirt in the water sample rolls from the obliquely arranged filter screens 600 to the dirt discharge port 510 and is discharged to the dirt bin 400, according to the characteristics of the large-caliber dirt discharge opening 510 of the inclined filter cavity 500 of the rolling filter, by utilizing the self pressure of the pipeline flow, when water flows into the filter cavity 500, one part of water flows through the filter screen 600 of the filter cavity 500 to enter the clean water bin 300 and passes through the outlet of the clean water bin for use by analytical equipment, the other part of water flows and impurities are filtered into the sampling branch of the instrument through the wall of the cone-shaped filter screen 600 by a small water source in the high-position pressure-resistant self-washing filter cavity, so that the normal sampling of the instrument is ensured, and particles with the mesh number larger than that of the filter screen 600 pass through the filter along with the pipeline water flow are formed into the large outlet of the filter cavity 500 by the obliquely arranged filter screen 600 towards the low position and roll.

Filter screen 600 be half cone structure, and the one end internal diameter that filter screen 600 is close to water sample import 210 is less than the internal diameter of filth escape orifice 510, the filth escape orifice 510 of heavy-calibre really reaches impurity and can not adhere on filter screen 600, guarantees the continuity of analytical instrument water intaking.

The filter box cover 200 and the filter box body 100 are fixedly assembled through the fastening bolts 220, the screw assembling and fixing effects are good, the installation and the disassembly are convenient, the operation is convenient, and the sealing effect is good by matching with the sealing washer 230.

The contact part between the filter box cover 200 and the filter box body 100 is provided with a sealing gasket 230, and the sealing gasket 230 has a good sealing effect, so that the sewage in the filter box is prevented from overflowing from the space between the filter box body 100 and the filter box cover 200.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that simple modifications and substitutions by those skilled in the art are within the scope of the present invention without departing from the spirit and scope of the present invention.
