Abstract

The utility model discloses a leveling filter head, comprising a filter cap (1), a pre-embedded element (2), and a filter rod (7), wherein the upper and middle portions of the pre-embedded element (2) and the upper portion of the filter rod (7) are arranged with screws (6), the filter cap and the filter rod are connected and engaged with the pre-embedded element via screws, the lower end of the filter rod is arranged with a filter screen (10), the upper end of the filter rod is provided with an open slot (10), the upper end of the filter rod (7) is arranged with a ratchet sheet (4) at outer surface integrated with the filter rod, the inner hole of the pre-embedded element (2) is arranged with a positioning bar (5) integrated with the pre-embedded element, the ratchet sheet (4) has flexibility. When adjusts the filter rod, the ratchet sheet (4) on the filter rod can overpass the positioning bar (5), therefore, when the filter rod is adjusted in the pre-embedded element, the utility model can avoid special spanner to level the air outlets on the filter head at one plane, to confirm uniform reverse-washing effect, with better washing effect, short reverse-washing time, easy installment and adjustment of filter head, saved time and saved installment cost.

Description

The leveling filter

Technical field

The utility model relates to a kind of hydrotreater filter, the leveling filter on especially a kind of hydrotreater filter.

Background technology

At present, in UBAF fresh water (FW) processing procedure, two ends all to be housed on the filter plate in its filter tank all with the filter of filtering cap, not only its water treatment good filtration effect, and its filter cap is difficult for stopping up, and clears up also very convenient, thereby water treatment efficiency is higher, and water treatment operating cost is lower.At present, adjustable filter all adopts threaded adjusting and uses nut check, but use the filter of this nut check structure, also there is following weak point: the one, need special-purpose special spanner that nut is locked, each filter needs a nut, because filter installation quantity is big, thereby special-purpose special spanner quantity is many, thereby mounting cost and material cost height; The 2nd, it is not too convenient to operate when nut check is installed, and installation effectiveness is lower; The 3rd, need the workman below filter plate, to install, labour intensity is big, and working environment is bad, inefficiency.

The utility model content

At the problem that above-mentioned existing adjustable filter exists, the utility model provides a kind of fitting operation convenience, has not needed locking nut and special-purpose special spanner, installation effectiveness height and mounting cost and the leveling filter that the cost of material is low.

The purpose of this utility model is to realize like this, it comprises the filter cap described leveling filter, the filter bar, built-in fitting, described built-in fitting casting is fixed on the filter plate, at built-in fitting inner chamber epimere and middle part and filter bar epimere be equipped with screw thread, filter cap and filter bar and built-in fitting screw thread are movably connected, be provided with venthole and disappointing groove at filter bar hypomere, be provided with grating in filter bar lower end, be provided with open slot in filter bar upper end, be provided with and filter rod all-in-one-piece spinal plate at filter bar epimere outer surface, be provided with the positioning strip that forms one with built-in fitting on the axial inner surface of built-in fitting two thread segments, described spinal plate has elasticity, when regulating the filter bar, the spinal plate on the filter bar can be crossed positioning strip.

The open slot of described filter bar upper end is two, and is symmetrical arranged, and also can be other a plurality of open slots, evenly is provided with at interval; The grating of described filter bar lower end is an integral body with the filter bar, and the external diameter of its grating is less than filter bar external diameter, and the effluent trough on the described filter cap is inclined upwardly a little, and the width of the effluent trough on its filter cap is greater than the effluent trough width on the grating.

The utility model is owing to be provided with screw thread and positioning strip in built-in fitting, on the filter bar, be provided with screw thread and the spinal plate that matches with built-in fitting, thereby when its filter bar is regulated in built-in fitting, do not need special-purpose special spanner and locking nut, just can guarantee to regulate venthole position on the filter on same horizontal plane, can not only guarantee that backwash effect is even, cleaning performance is good, and the filter fitting operation is convenient, and it is low that labour intensity is installed, and saves mounting material and installation work-hour expense.

Description of drawings

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the A-A cutaway view of Fig. 1.

In the drawings, 1, filter cap 2, built-in fitting 3, open slot 4, spinal plate 5, positioning strip 6, screw thread 7, filter bar 8, venthole 9, groove 10, grating lose heart

The specific embodiment

In Fig. 1 and Fig. 2, the utility model is by filter cap 1, filter bar 7, built-in fitting 2 is formed, built-in fitting 2 is ladder barrel shape, built-in fitting 2 casting are fixed on the filter plate, at built-in fitting 2 endoporus epimeres and middle part and filter bar epimere be provided with screw thread 6, its built-in fitting lower end is a taper barrel, on internal surface of hole on the built-in fitting 2, be provided with four positioning strips of evenly arranging 5, positioning strip 5 forms with built-in fitting 2 whole manufacturings, positioning strip 5 highly is enough to stop spinal plate 4 freely to cross positioning strip, positioning strip 5 can be one, also can be other many evenly is provided with at interval, on filter bar 7 outer surfaces, be provided with and filter the spinal plate 4 of rod all-in-one-piece, when positioning strip is four, spinal plate is preferably two symmetric arrangement, certainly spinal plate also can be a slice, the outermost end size of spinal plate 4 is less than built-in fitting top circular hole internal diameter, described spinal plate 4 has certain elasticity, when regulating the filter bar with the external force rotation, spinal plate 4 can be crossed positioning strip 5, when stopping to regulate the filter bar, spinal plate 4 is limited between the positioning strip 5, because spinal plate 4 free slewing area between positioning strip 5 is very little, thereby spinal plate freely rotates the distance that causes that the filter bar moves up and down, relative filter bar is regulated the error that highly allows and can be ignored, thereby can be with filter bar 7 relative fixed, filter cap 1 is provided with acclivitous a little effluent trough, the effect that the loss of flood peak is reduced is arranged, the width of its filter cap 1 upper water-out groove is greater than the width of grating 10 upper water-out grooves on the filter bar, make suspension be difficult for stopping up the filter cap, its filter bar 7 bottoms are provided with venthole 8 and disappointing groove 9 simultaneously, filter bar 7 lower ends also are provided with the grating 10 of the vertical barrier type structure of taking tank out of, grating is made with the filter bar is whole, and grating 10 external diameters are less than filter bar 7 external diameters, the filter bar is laterally taken up room to be reduced, the filter bar is arranged more compact and reasonable, filter bar 7 tops are arranged with two open slots 3, also can be four grooves or six grooves that evenly are provided with, when regulating the filter bar, only need insert in the open slot 3, just can regulate the height of filter bar with light instrument.
