Abstract
The utility model discloses a special filter element for an automatic reverse-flushing filter. The special filter element comprises an upper joint, a lower joint and a punched-plate framework, wherein a filtering net is attached on the punched-plate framework; a hydraulic rotating element is mounted in the middle of the filter element. According to the special filter element for the automatic reverse-flushing filter, disclosed by the utility model, the hydraulic rotating element with a special design is adopted and can solve the problems that the conventional filter element structure is easily blocked by large foreign matters, and ideal reverse-flushing effect cannot be realized in the filtering net; the special filter element has a good reverse-flushing effect, is ingenious in design, easy to implement, and suitable for vertical type and horizontal type full-automatic reverse-flushing filters.
Description
Technical field
The utility model belongs to the full-automatic back washing filter field, belongs to specifically a kind of single-purpose filtering element in this field.
Background technology
The filter cartridge construction of filter is generally check configuration or bi-directional configuration at present; bi-directional configuration filter core wherein; because its two-way water inlet; and the inner retaining element of installing is such as truncated conical shape, with respect to the unidirectional filter core of comparable size; two-way filter core has the actual usable floor area of filter screen large; the advantages such as backwash effect is good, but the impurity of bulky grain or strip is easily stopped up by the intermediary element of two-way filter core inside, thus affect the operating efficiency of filter.
The utility model content
Technical problem to be solved in the utility model just provides a kind of minimizing foreign material and stops up, and optimizes the single-purpose filtering element of backwash effect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of automatic backwashing filter single-purpose filtering element comprises the filter core top connection, the filter core lower contact, and filter core punched-plate skeleton is attached with screen pack at filter core punched-plate skeleton, at the middle part of filter core the waterpower driven rotary element is installed.
Further, described waterpower driven rotary element is installed on the filter core by the mode of sintering and/or welding.
Further, described waterpower driven rotary element is impeller shape.
Further, the impeller of described waterpower driven rotary element is two.
The beneficial effects of the utility model are:
Automatic backwashing filter single-purpose filtering element disclosed in the utility model, waterpower driven rotary element by particular design, can solve present filter cartridge construction is easily stopped up by large-scale foreign material, the problem that filter screen inner counter developing result is undesirable, this single-purpose filtering element backwash effect is good, design ingeniously, easy to implement, be applicable to vertical and Horizontal type automatic backwash filter.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1 disclosed automatic backwashing filter single-purpose filtering element.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Embodiment 1, and as shown in Figure 1, the present embodiment discloses a kind of automatic backwashing filter single-purpose filtering element, comprise filter core top connection 1, filter core lower contact 5, filter core punched-plate skeleton 4, be attached with screen pack 3 at filter core punched-plate skeleton, at the middle part of filter core waterpower driven rotary element 2 be installed.Described waterpower driven rotary element is installed on the filter core by the mode of sintering and/or welding.Described waterpower driven rotary element is impeller shape.The impeller of described waterpower driven rotary element is two.
When filter core carries out the backwash state, impeller shape waterpower driven rotary element is owing to pressure reduction rotates in the middle of the filter core, the turning effort of waterpower driven rotary element makes particularly backwash side of filter core inside form spiral flow field, thereby the impurity that is attached to filter core inside more easily is rinsed; When backwash was carried out in the opposite side outlet of filter core, the waterpower driven rotary element can counter-rotate, even large granular impurity is blocked in waterpower driven rotary element place like this, also can therefore rinse out.
Traditional filter-core back-flushing is washed in the process, and the flow field of filter core inside is the linear pattern flow field, and is although retaining element has played the speedup effect to the recoil wash in the middle of it, middle in case obstruction can greatly reduce backwash effect; And the disclosed filter core of the present embodiment, wash side at filter-core back-flushing obviously strong spiral flow field is arranged, and this spiral flow field direction is washed alternately changing of side according to filter-core back-flushing, thereby make the filter core mid portion, the impurity that is attached to the impurity on the screen pack or is blocked in the waterpower driven rotary element all is easy to be rinsed.
The disclosed automatic backwashing filter single-purpose filtering element of the present embodiment, waterpower driven rotary element by particular design, can solve present filter cartridge construction is easily stopped up by large-scale foreign material, the problem that filter screen inner counter developing result is undesirable, this single-purpose filtering element backwash effect is good, design ingeniously, easy to implement, be applicable to vertical and Horizontal type automatic backwash filter.
