Abstract

The utility model relates to a filter plate used in filter tanks and comprises a plate body (1) and screw holes (2) which are arranged on the plate body (1) and used for installing a filter head; wherein, the screw holes (2) are uniformly distributed on the plate body (1) and formed by embedded parts; inclined planes (11) are positioned on both sides of the plate body (1); semicircular gaps (12) are respectively arranged on both ends of the plate body (1). The filter plate of the utility model is made of reinforced concrete and composite materials; compared with the prior art, the filter plate enables a plurality of filter plates to be provided with a groove which is provided with an inverted triangular section for pouring the concrete and arranged at the splicing position between the two neighboring filter plates when a plurality of filter plates are mutually spliced, so with the mode that the neighboring filter plates can be connected through the pouring of the concrete, no gaps exist among the filter plates and the total sealed state is reached, which ensures the sealing performance and the firmer connection of the filter plates.

Description

A kind of filter plate that is used for filtering ponds

Technical field

The utility model relates to a kind of technical field of filtering ponds, relates in particular to a kind of filter plate that is used for filtering ponds.

Background technology

Filtering ponds are quite extensive in Application for Field such as town water supply processing, industrial water supply processing, industrial cycle water treatment, sewage disposals.Present filtering ponds generally are made up of filtering ponds pond body, filtrate filtering layer, filtrate bearing device and the water dispensing apparatus etc. that is used for the backwash filtrate.Filtrate bearing device wherein generally adopts filter plate, be a kind of sheet material that is evenly distributed with mesh or slit, and the filtrate in the filtering ponds has the cobble of employing, quartz sand or anthracitic, also have and adopt fiber filtering, existing common filter plate adopts PP (polypropylene) reinforcement plate, bearing capacity is relatively poor in actual the use, can only reach 500kg/m ², filter plate deforms easily, and the glacing flatness of its amount of deflection increase, filter plate is descended, and can have a strong impact on the normal use of filter plate, then the performance of influence filtration; And, need be equipped with filter toward contact on the filter plate in order to realize backwash process, this has just increased the burden of filter plate more.

On the other hand, because the area of filtering ponds pond body is bigger, the filter plate in filtering ponds is spliced by a plurality of unit filter plate often, and such as 500mm * 333mm specification, it can be combined into 1m ², 1.5m ²And the area of plane of multiple, make filter plate can be applicable to the filtering ponds of different sizes, each unit filter plate is fixed on the filter beam by screw, and existing four sides of filter plate are vertical plane, during actual installation, be prone to the slit in splicing place between two filter plates, water purification after the filtration and backwashing water are easily from the random percolation in the slit between the filter plate and mistake, therefore, existing filter plate sealing property when practice can not be guaranteed.

Summary of the invention

Technical problem to be solved in the utility model is the filter plate that is used for filtering ponds that can guarantee sealing property when providing a kind of actual installation at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the filter plate of filtering ponds, includes plate body and be opened in being used on the plate body screw of filter is installed, and it is characterized in that: the both sides at described plate body are provided with the inclined plane.

Wherein, filter plate adopts armored concrete and composite to make, promptly in concrete, add fibrous composite, like this, not only can avoid filter plate in prefabricated process, to crack, but also can improve the intensity and the toughness of filter plate, make the filter plate of 50mm thickness just can guarantee to bear 1000kg/m ²Load.

For evenly collecting filter back water purification, described screw is good on the plate body to be evenly distributed on, and can adopt steel or plastic built-in fitting to form, and like this, filter just can be evenly distributed on the filter plate accordingly.

As further improvement, the two ends of described plate body can be respectively arranged with semicircle breach, and like this, filter plate can pass this semicircle breach by follower bolt and be installed on the filter beam, conveniently carries out fastening to filter plate.

Compared with prior art, the utility model advantage is: be designed to the inclined plane by the both sides with the filter plate plate body, make the polylith filter plate when splicing mutually, splicing place between adjacent two filter plates, be between both inclined planes, have a cross section and be the groove of del, for concrete pouring, like this, there is not the slit in the mode that adjacent filter plate is coupled together by concrete casting between the filter plate, reach the state of sealing fully, guaranteed the sealing property of filter plate, and connected also more firm; And be covered with whole filtering ponds plane by the splicing of polylith filter plate, practical application is very flexible, can adapt on the filtering ponds of different sizes.Filter plate of the present utility model adopts armored concrete and composite to make, and design feature is in conjunction with the material behavior of filter plate, and is simple in structure, fixed, and good seal performance is easy to implement.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 be among Fig. 1 A-A to cutaway view.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 2, the filter plate that this is used for filtering ponds includes plate body 1 and is opened in being used on the plate body 1 screw 2 of filter is installed;

Described screw 2 is to be evenly distributed on the plate body 1, and adopts built-in fitting to form;

Be provided with inclined plane 11 in the both sides of described plate body 1, the two ends of plate body 1 are respectively arranged with semicircle breach 12.

Claims

1, a kind of filter plate that is used for filtering ponds includes plate body (1) and is opened in the screw that is used to install filter (2) on the plate body (1), it is characterized in that: be provided with inclined plane (11) in the both sides of described plate body (1).

2, the filter plate that is used for filtering ponds according to claim 1 is characterized in that: described screw (2) is to be evenly distributed on the plate body (1), and adopts built-in fitting to form.
