Abstract
The utility model relates to a gas-water back-flushing filter head of a filter pond in water treating engineering, comprising a filter handle and a sleeve tube, wherein, the filter handle and the sleeve tube are in threaded connection; the top of the filter handle is fixedly provided with a cap lid; a cap ring provided with a transversal rib and bottom seam is sheathed between the cap and the sleeve tube. The utility model can uniformly distribute water and air, has favorable back-flushing effect but no dead angle area, and is suitable for homogeneous filter pond. Due to the improvement of the structure, the utility model is very easy to install.
Description
The utility model relates to air-water backwashing filter in filter tank in the engineering of water treatment.
The K type filter that uses in the filter tank at present can not satisfy the uniform requirement of water and air distributing under the condition of homogeneous filtering material, also exists dead angle area during other improved filter distribute water and airs, and hydraulics is bad.In addition, existing filter is structurally all by the filter cap, and filter handle and sleeve pipe are formed, and the filter cap needs fixed bonding on the filter handle during installation, troublesome poeration.
The utility model is to design a kind of novel air-water backwashing filter, and this filter can adapt to the flushing needs in homogeneous filter tank, and distribute water and air does not have dead angle area, and construction and installation simultaneously can be very convenient.
Design of the present utility model is such: a kind of air-water backwashing filter, comprise sleeve pipe and filter handle, and sleeve pipe and filter handle are filtered the handle top and are set firmly cap for being threaded, and hatband is sheathed between cap and the sleeve pipe, establishes the cross rib bar and the end on the hatband and stitches.
Hatband of the present utility model is set between the cap and sleeve pipe of filter handle, cap is arranged on when hatband is installed, and sleeve pipe is arranged down, promptly hatband is fixed between cap and the sleeve pipe when the filter handle is tightened on sleeve pipe, has realized a step integral installation, and is easy and simple to handle.Establish the cross rib bar and end seam and make filter realize that in use bubble diameter is little on hatband, be evenly distributed, distribute water and air does not have dead angle area, has improved hydraulics, and backwash effect is good, adapts to use in the homogeneous filter tank.
Fig. 1 is the structural representation of filter handle of the present utility model
Fig. 2 is the structural representation of hatband of the present utility model
Fig. 3 is the structural representation of sleeve pipe of the present utility model
Fig. 4 is the utility model assembling schematic diagram
Below the utility model is described in further detail in conjunction with the accompanying drawings with an embodiment.
As shown in Figure 1, present embodiment filter handle 1 comprises the cap 4 of upper end, hollow filter bar 5 and external screw thread 6.Hollow filter bar 5 bottom bar sides are established one group of narrow slit 7, use for the air inlet water inlet.
As shown in Figure 2, the hatband 2 of present embodiment vertically is provided with finedraw 8, laterally is provided with cross rib bar 9, leaves end seam 10 in the bottom of hatband 2.
As shown in Figure 3, establish internal thread 11 in the sleeve pipe 3 of present embodiment, with above-mentioned external screw thread 6 couplings.
As shown in Figure 4, present embodiment middle sleeve 3 is fixed on the filter plate in filter tank in use, puts packing ring 12 in sleeve pipe 3 upper ends, for needing of sealing.Establish hatband 2 on packing ring 12, filter handle 1 is inserted in sleeve pipe 3, and in packing ring 12 and the hatband 2, cap 4 is pressed on the hatband 2.Screw by internal and external screw thread 11,6 couplings, fastening above-mentioned each parts are installed a step and are finished.G﹠W mixes in filter during use, through the slit of hatband 2 to filtering layer water distribution uniformity gas distribution.
