Abstract
The utility model discloses a mechanical filter, which comprises a water inlet pipe and a water distribution sieve pipe. The upper end of the water distribution sieve pipe is fixedly connected with the water inlet of the water inlet pipe. The lower end of the water distribution sieve pipe is sealed. The lower end of the water distribution sieve pipe is sealed by a stainless steel plate. The diameter of the water distribution sieve pipe is larger than the diameter of the water inlet pipe. The water distribution sieve pipe is fixedly connected with the water inlet pipe through a flange. The utility model has the advantages the water can be evenly distributed, the effect of water distribution is favorable, full exchange between the raw water the filter medium in the filter layer is ensured, the filter effect is good, filter material losses are reduced, the cost is saved, no filter material is flushed out of the device through the sieve pipe during backwashing and unnecessary losses are reduced.
Description
Technical field
The utility model discloses a kind of mechanical filter that raw water filtration is used that is used for, the prime that is mainly used in recirculated water equipment, supply equipment and the pure water of each enterprises and institutions is handled.
Background technology
Mechanical filter is the device that is used for filtering out the impurity in the former water, and cardinal principle is to want former water to pass through the multiple filtration layer successively to remove the harmful substance in the water.Because of mechanical filter water inlet is press water, if directly water inlet then can destroy filtering layer causes percolation, so water-distributing device must be arranged.The effect of water-distributing device is that former water is evenly distributed, and water is fully contacted with filter medium, to reach best filtering and impurity removing effect.The water-distributing device of tradition mechanical filter is that a stop plank is set below water inlet pipe, links to each other with end socket with four reinforcing bars, and current impinge upon and are reflected on the stop plank on the end socket like this, drip from end socket, thereby reach the shunting purpose.Though such stop plank provides cost savings, and easy to make, Currency end is also extremely obvious: it is inhomogeneous to mainly contain water distribution, and filtering layer is had 5-20 centimetre of destruction of not waiting; During backwash, have filtrate and go out from water inlet, cause the filtrate loss, all must increase the 5%-10% filtrate every year, increased old.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of water distribution evenly, the mechanical filter of good filtration effect.
Technical scheme: a kind of mechanical filter, comprise water inlet pipe, it also comprises the water distribution screen casing, the upper end of water distribution screen casing and the fixed installation of the water inlet of water inlet pipe, the lower end sealing of water distribution screen casing.
Wherein, the lower end of water distribution screen casing seals with stainless-steel sheet.
Wherein, the diameter of water distribution screen casing is greater than the diameter of water inlet pipe.
Wherein, described water distribution screen casing is fixedlyed connected by flange with water inlet pipe.
Wherein, establish filtrates such as anthracite, quartz sand in the mechanical filter, divide into supporting layer, former water enters from the water inlet of top, and in the water-distributing device access arrangement, former water passes through filter course from top to bottom, suspension in the water, colloid, microorganism are held back by filtrate, thereby reach the purpose of filtration.After filter work a period of time, the dirt of holding back in the filtering layer is more and more, fills up the gap between filtrate gradually, at this moment the filter capacity of equipment dies down, must carry out backwash to equipment from bottom to top, carry out work after backwash is finished again, thereby form a working cycles.
Beneficial effect: (1) water-distributing device of the present utility model, water distribution is even, and water distribution is effective, thereby makes the filter medium in former water and the filter course fully exchange good filtration effect.(2) water-distributing device of the present utility model has significantly reduced intake pressure, and Gu Buhui damages filter course, has reduced the filtrate loss, thereby has saved cost.(3) during backwash, filtrate can not gone out equipment by screen casing, reduces and causes unnecessary loss.
Description of drawings
Fig. 1 is an existing machinery structure of filter schematic diagram.
Fig. 2 is the enlarged diagram at A place among Fig. 1.
Fig. 3 is a structural representation of the present utility model.
Fig. 4 is the enlarged diagram at B place among Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The structural representation of the water-distributing device of existing mechanical filter as shown in Figure 1, mechanical filter is a kind of column type equipment, in establish filtrates such as anthracite, quartz sand, divide into supporting layer, former water enters from the water inlet pipe of top, in access arrangement in the water-distributing device, passes through filtering layer from top to bottom.Suspension in the water, colloid, microorganism are held back by filtrate, thereby reach the purpose of filtration.After filter work a period of time, the dirt of holding back in the filtering layer is more and more, fills up the gap between filtrate gradually, at this moment the filter capacity of equipment dies down, must carry out backwash to equipment from bottom to top, carry out work after backwash is finished again, thereby form a working cycles.
As shown in Figure 2, the water-distributing device of original mechanical filter is for to be provided with a water fender 1 in housing, and water fender 1 usefulness reinforcing bar 3 is fixed on the end socket 2.The water that water inlet from end socket 2 enters drops on the water fender 1, because water inlet is a press water, reflexes on the end socket 2 after beating on water fender 1 so intake, and drips from end socket 2 then, thereby reaches the purpose of water distribution.
The structural representation of the utility model water-distributing device is shown in Fig. 3,4, and an end of water distribution screen casing 4 of the present utility model is fixed on by flange 5 on the delivery port of water inlet pipe 6, and the other end of water distribution screen casing 4 is equipped with the corrosion resistant plate sealing.Press water in the water inlet pipe by tiny screen pipe opening form water smoke to around spray, not only evenly but also can not form bigger current and destroy filtering layer, and during backwash, filtrate can not gone out equipment by screen casing, causes unnecessary loss.Wherein, the diameter of water distribution screen casing 4 is greater than the diameter of water inlet pipe 6.
The utility model provides a kind of thinking and method of mechanical filter; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also do some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
