Abstract

A basket filter comprises a seat body with a water inlet and a water outlet, a filter basket arranged in the seat body and a cover plate covered on the upper surface of the seat body, wherein the cover plate is screwed and fixed on the surface of the seat body through a plurality of sets of bolt structures; the bottom of the dirt collecting hopper is provided with a drain pipe, and a drain valve is arranged after the drain pipe extends out of the side wall of the bottom of the seat body. The filtering basket comprises a basket net with filtering holes densely distributed on the upper part and a funnel-shaped sewage collecting hopper on the lower part; the bottom of dirty fill of collection is equipped with the blow off pipe, is equipped with the drain valve after its lateral wall that stretches out the pedestal bottom, so in whole filtering process, the filth of filtering out slowly deposits the back and collects the dirty fill of collection, when the filth collects the certain degree, unscrews the drain valve, just can make the filth automatic discharge go, just so need not unscrew bolt structure one by one and open the apron and just can take out the filter basket and come the decontamination, therefore its structure is more reasonable, it is more convenient to use.

Description

basket filter

technical field

The invention relates to a swimming pool or aquarium equipment, in particular to a filter used to filter water in a swimming pool or a culture pond.

Background technique

The current filter used to filter the water in the swimming pool basically adopts the basket structure of the filter basket. After the sewage enters the water inlet of the filter, the filter basket with dense mesh on the surrounding wall intercepts and filters the dirt. Finally, relatively clean water flows out from the mesh, and then discharged from the outlet of the filter to achieve the purpose of filtration. The current type of basket filter, after using for a period of time, needs to twist many bolts on the top surface of the filter to open the cover plate, and then the filter basket in the filter can be taken out to pour out the dirt, and then Then put the filter basket back, cover the cover again, and finally lock all the bolts. As can be seen from the above, the current basket filter is very inconvenient when dumping the filtered dirt, so the applicant has improved the basket filter.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a basket filter with a more reasonable structure and more convenient use.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

A basket filter, comprising a base body with inlet and outlet ports, a filter basket installed in the base body, and a cover plate covering the upper surface of the base body, the cover plate is screwed and fixed to the base body through multiple sets of bolt structures On the surface, the filter basket includes a net with filter holes densely covered on the upper part and a funnel-shaped dirt collecting hopper at the lower part; There is a drain valve.

In an improved solution to the above-mentioned basket filter, the filter basket is eccentrically loaded into the seat body and leans against the water inlet; a filter basket water inlet facing the water inlet is opened on the basket net.

In an improved solution to the above-mentioned basket filter, the filter basket is inserted and installed into the seat body through an eccentric plate, and the eccentric plate is inserted into the seat body with a transition fit.

Compared with the prior art, the beneficial effects of the present invention are: since the filter basket includes a basket with densely covered filter holes on the upper part and a funnel-shaped dirt collecting bucket at the bottom; a sewage discharge pipe is arranged at the bottom of the dirt collecting bucket, which There is a drain valve behind the side wall protruding from the bottom of the seat body, so during the whole filtration process, the filtered dirt slowly settles down and is collected into the dirt collection bucket. When the dirt is collected to a certain extent, unscrew it to drain valve, the dirt can be automatically discharged, so that every time the dirt needs to be cleaned, it is not necessary to unscrew the bolt structure one by one to open the cover plate to take out the filter basket for cleaning, so the structure of the present invention is more reasonable and more convenient to use.

Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

【Description of drawings】

Fig. 1 is the three-dimensional schematic diagram of the embodiment of the present invention;

Fig. 2 is the structural representation of the embodiment of the present invention;

Fig. 3 is the assembly schematic diagram of the embodiment of the present invention;

Fig. 4 is a schematic perspective view of a filter basket according to an embodiment of the present invention.

【detailed description】

The present invention is a basket filter, as shown in Figures 1 to 4, comprising a seat body 1 with inlet and outlet ports 11, 12, a filter basket 2 installed in the seat body 1, and a cover on the seat body 1 upper surface The cover plate 3 is screwed and fixed to the surface of the seat body 1 through multiple sets of bolt structures 4. Here, the filter basket 2 includes a basket 21 densely covered with filter holes 211 on the upper part and a funnel-shaped lower part. Sewage collecting bucket 22 ; a sewage discharge pipe 5 is provided at the bottom of the sewage collecting bucket 22 , and a drain valve 6 is provided behind the side wall of the bottom of the seat body 1 . When the basket filter is working, the sewage enters the filter basket 2 from the water inlet 11. At this time, the dirt in the water cannot pass through the filter hole 211, so the relatively clean water after filtering comes out from the filter hole and then passes through the water outlet. 12 discharge, during the whole filtration process, the filtered dirt slowly settles down and is collected into the dirt collection bucket 22, when the dirt is collected to a certain extent, unscrew the drain valve 6, and the dirt can be automatically discharged , When decontamination is to be done every time like this, it is not necessary to unscrew the bolt structure 4 one by one and take out the filter basket to decontaminate after the cover plate is opened, so the structure of the present invention is more reasonable and more convenient to use.

The filter basket of the current filter is located in the center, so that the filtered water will come out evenly from the filter holes around the filter basket, and will hit the inner wall of the seat body and then backwash, making the flow of filtered water more chaotic. This is not conducive to the discharge of filtered water. For this reason, preferably, as shown in Figures 2 to 4, the filter basket 2 is eccentrically loaded into the seat body 1 and leans against the water inlet 11; The filter basket water inlet 212 of the water port 11. Since the filter basket 2 leans eccentrically towards the water inlet, the water flow can flow smoothly from the filter hole 211 to the water outlet 12, thereby facilitating the filtration and drainage of water; The water outlet makes the space A towards the water outlet 12 in the seat relatively large, which can reduce the resistance of the water pump connected to the water outlet, thereby facilitating drainage. Preferably, the angle of the dirt collecting bucket 22 is the best between 55-60, because if the angle is too small, the dirt collecting bucket will be done relatively high, resulting in a larger shape of the whole filter; and if the angle is too large If it is not, it is not conducive to the dirt in the sewage collecting bucket to slide to the bottom of the bucket, which is not conducive to sewage discharge.

In order to facilitate the installation of the filter basket, here, the filter basket 2 is inserted into the seat body 1 through the eccentric plate 7, and the eccentric plate 7 is inserted into the seat body 1 with a transition fit, and the eccentric plate can also make The filter basket avoids shaking under the impact of water.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art through this disclosure that the present invention can be modified without departing from the principle and spirit scope of the present invention defined by the claims. various changes or modifications. Therefore, the detailed description of the embodiments of the present disclosure is only for explanation, not for limiting the present invention, but the scope of protection is defined by the content of the claims.
