Abstract
The utility model discloses an adjustable filter head of a cast-in-place filter plate. The adjustable filter head comprises a filter cap, a filter seat, a filter rod and a template, wherein the filter cap and the filter seat are fixed through threaded connection; the filter seat is in threaded connection with the filter rod and the template respectively; and matched fixing clamp strips are arranged on the filter rod and the template. The filter rod can be adjusted up and down in the filter seat and has good fastening perforamnce. The adjustable filter head disclosed by the utility model is mounted and controlled by a template; and due to the dimensional consistency of the filter seat product and the close fit between the filter seat and the template, the levelness of the top surfaces of the template and the filter seat is controllable, and the levelness of the cast-in-place reinforced concrete filter plate is ensured in a controllable range; Through the thread adjustment of the filter seat and the filter rod, the back-washing air inlet hole and air inlet strip slit of each filter rod can be conveniently kept at the same horizontal height, and the requirements on quality are sufficiently met; and since the matched clamp strips fixed in interference fit are arranged on the filter rod and the filter seat or template, the position of the filter rod does not change due to the back-washing vibration. The long-term operation effect of the air-water back washing and filtering of a filter pond is guaranteed.
Description
Technical field
The utility model belongs to water-treatment technology field, relates to a kind of cast-in-place filter plate pattern adjustable filter head.
Background technology
Filtration plays the final effect of checking on as a critical process of waterworks, sewage treatment plant to the whole system treatment effect, and its operating condition directly influences the quality of water factory's product water.And the regeneration of filter ability is again the key of filter tank stable and high effective operation.Be to improve the recovery effects of filter tank filtering layer retaining power, along with development of technology adopts in newly-built, the reconstruction filter tank of water factory in recent years: first gas is washed, and gas, water are united and washed again, and gas, the water backwashing mode of washing have obtained comparatively satisfied effect at last.
And the gas in filter tank, water backwashing the most key be backwash air inlet between each filter of control, inflow uniformity.Stipulate in " plumbing design manual " the 3rd town water supply that for this reason " when prefabricated board was installed, the horizontal error of every block of plate should be less than 1mm, and the horizontal error of whole pond inner plate surface must not be greater than 3mm." be in each same level height basically respectively to guarantee each filter air admission hole, air inlet bar shaped seam.
The filter plate that use at present in gas, water backwashing filter tank has two kinds of prefabricated filter plate and cast-in-place filter plates; Filter also has fixed and adjustable two kinds.Fixedly be adapted to prefabricated filter plate; Adjustable filter is adapted to cast-in-place filter plate especially, also is adapted to prefabricated filter plate.Application number is that 200610110597.0 one Chinese patent application discloses a kind of pattern adjustable filter head, by built-in fitting, is screwed in the adjustable type filter cap at built-in fitting top, is contained in the inner filter bar of built-in fitting and forms.Two or more regulating parts are arranged at the top of filter bar, and two groups or more zigzag barb is arranged at the bottom of built-in fitting.This pattern adjustable filter head has strengthened the horizontal error scope of cast-in-situ steel reinforced concrete filter plate to a certain extent owing to exist between filter block and the template and cooperate untight problem; And not good maybe the long-time running effect in gas, water backwashing filter tank being had a negative impact of tightness of filter bar.
The utility model content
The goal of the invention of the utility model is: the problem to above-mentioned existence provides a kind of cast-in-place filter plate pattern adjustable filter head.This cast-in-place filter plate pattern adjustable filter head is skillfully constructed, and is simple in structure, cooperates tight between good, the filter block of tightness of filter bar and the template.
For realizing above-mentioned purpose, the utility model solves the technical scheme that its technical problem adopted and is:
Cast-in-place filter plate pattern adjustable filter head comprises filter cap, filter block, filter bar and template, and said filter cap is connected fixing with filter block; Said filter block is threaded fixing with filter bar and template respectively; Said filter bar and template are provided with the card article that is threaded and is complementary.
As optimal way, said filter block is provided with and filters the card article that the card article of bar is complementary.
As optimal way, also be provided with the non-return latch that is complementary on said filter block and the template.
As optimal way, said filter block also is provided with the non-return latch that vertically is complementary with filtering on the cap.
Adopt between the utility model filter bar and filter block or the template to be threaded, and be provided with the card article that is complementary.Rotate the filter bar and regulate filter bar high and low position relatively in filter block, through being arranged on card article and the interference fit between the card article on filter block or the template on the filter bar, reach relative fixed, loosening purpose is threaded when preventing to shake.Can suitably adjust value of interference fit according to the mechanical property of injected plastics material during Mould Machining, make the filter bar of injection moulding in filter block, both can regulate the relative high and low position of filter bar through rotating; Can make its relative fixed and not damage card article through card article again.
The utility model filter filter block also is provided with the vertical non-return latch that is complementary with filtering on the cap; Can prevent to filter cap and fail to tighten fully the filter cap because of tight perhaps other transient causes of quality control on construction; Cause the filter tank in long-time running, filter cap case accident in gas, the water backwashing vibrations.
Also be provided with the non-return latch that is complementary on the utility model filter filter block and the template, it is loosening to be threaded in the time of can preventing in cast-in-situ concrete construction vibrations, cooperates tight between filter block and the template.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
The utility model discloses a kind of cast-in-place filter plate pattern adjustable filter head, be skillfully constructed, simple in structure.Comprise filter cap, filter block, filter bar and template.Said filter cap is threaded fixing with filter block, filter block is threaded with filter bar and template respectively, and filter bar and template are provided with the fixing strip that is complementary.But filter bar up-down adjustment and tightness in filter block is good.
The utility model closely cooperates between the uniformity of filter block product size, filter block and the template through the template installation and control, makes the levelness of template, filter block end face controlled, has guaranteed that the levelness of cast-in-situ steel reinforced concrete filter plate is in controlled range; Through the threaded adjusting of filter block with the filter bar, easily make backwash air admission hole, the air inlet bar shaped seam of respectively filtering bar be in same level height respectively, fully satisfy quality requirement; The interference fit that the card article that is complementary is set on logical filtering rod and filter block or the template is fixed, make the filter bar can the filter tank for a long time in long-time running, gas, water backwashing produce change in location in vibrating; Filter block also is provided with the vertical non-return latch that is complementary with filtering on the cap, can prevent the filter tank in long-time running, filter cap case accident in gas, the water backwashing vibrations.Ensured the long-time running effect of filter tank gas, water backwashing and filtration.
