Abstract
The utility model relates to a filtering unit of a disk sheet type filter, which belongs to the designing and manufacturing technology field of the filtering unit of the disk sheet type filter, and comprises a filtering unit shell body, backwashing thrust jets and a valve body. Three backwashing thrust jets are arranged in the filtering unit shell body; a tangential jet orifice is arranged on the wall of each thrust jet; and the three backwashing thrust jets are arranged in the shell body in a circumference trisection manner. Because the three backwashing thrust jets are arranged in the shell body and the tangential jet orifice is arranged on each thrust jet, the number of the jet orifices is increased, the flow speed of a backwashing medium is increased greatly, and the equipment pressure and the flow rate loss can be lightened. The filtering unit ensures the safe operation of the equipment, is an ideal filtering unit, and solves the problem that the existing product cannot meet the large flow need because the flow rate is limited.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of the filter element of discal filter.
Background technology
At present, employed filter element on discal filter is made of valve body and cell filter, and there is housing the cell filter outside, and there is the backwash jet pipe inside, the outer cover sabot sheet post of jet pipe.Valve body is positioned at the filter unit bottom.The backwash jet pipe is connected with the processing water pipe of valve body pars intermedia.But the backwash jet pipe in the existing product is a mono-tube design, and the tangential spray orifice amount that is provided with around jet pipe is relatively just few so, so will influence the flow and the flow velocity that are filtered medium, causes operating pressure to increase.Will bring hidden danger to equipment safety operation.In addition, existing valve body is the monofilm chip, because its flow is restricted.Therefore do not satisfy the needs of big flow.Therefore say that at present employed filter element is not very desirable in design on fluid device.
Summary of the invention
The purpose of this utility model provides a kind of filter filter element that can improve the flow that is filtered medium effectively.To solve the practical problem that existing product exists.
Structure of the present utility model is as shown in drawings: be made of filter element housing, backwash jet pipe and valve body.In filter housings, have three backwash jet pipes, on every jet pipe wall, all have tangential spray orifice.Three backwash jet pipes are pressed the setting of circumference trisection in housing, form a circulation passage between the backwash jet pipe.In the upper end of backwash jet pipe one clamping sleeve is arranged.At backwash jet pipe outside suit disc post.The disc post constitutes by filter is stacked.The clamping sleeve spiral-lock is in backwash jet pipe upper end, and seat is pressed on the disc post.Top at the backwash jet pipe has relief hole, in the filter element lower part of frame one valve body is arranged, and valve body lower portion has the unit media outlet.Side at valve body has medium inlet, a unit.Opposite side at valve body has a sewage draining exit.Be provided with tangent line eddy flow passage in the inboard, medium inlet.In eddy flow passage front one diaphragm valve valve port is arranged, there is an inlet diaphragm at diaphragm valve valve port place.There is a spring base diaphragm inboard, has spring on the spring base, and the top of spring contacts with diaphragm, at the rear side of tangent line eddy flow passage one blowdown barrier film valve port is arranged, and there is a sewage draining exit diaphragma of mouth sheet at blowdown barrier film valve port place.There is a spring base sewage draining exit diaphragm inboard, has spring on the spring base.The utility model is furnished with electric control gear and pressure source distributor, is used for monitoring media discharge pressure and flow, and commands each position to make corresponding action.Use of the present utility model is that it is installed on the discal filter.Medium inlet, media outlet and sewage draining exit are connected with respective line respectively.
The utility model is simple in structure, and is reasonable in design, owing to have three backwash jet pipes in the housing, all have tangential spray orifice on the every jet pipe, so just form the increase of nozzle hole number, can increase considerably the flow velocity of backwash medium, alleviated the loss of the pressure and the flow of equipment.Having ensured the safe operation of equipment, is a kind of desirable filter element.
