Abstract

The utility model discloses an automatic deslagging filter, which comprises a container with a liquid inlet and a liquid outlet, and a plurality of filter pipes which are arranged inside the container and possess the filtration function, wherein, inlets of the filter pipes are communicated with the liquid inlet, a front clapboard and a back clapboard are arranged inside the container, two ends of the filter pipes penetrate the font and the back clapboards and are hermetically fixed thereon, a mushroom valve which is matched with the size of the outlet is arranged in the position of the outlet of each filter pipe, a spring which is fixed at the bottom part of the container is arranged on the mushroom valve, the liquid outlet is arranged on the container wall between the front clapboard and the back clapboard, and a deslagging opening is arranged on the wall between the bottom part of the container and the back clapboard. Compared with the prior art, the filter realizes the automatic discharge of the residue, lowers the manufacturing cost, and possesses the high degree of automation.

Description

The automatic discharge filter

Technical field

The utility model relates to a kind of filter with automatic discharge function.

Background technology

In environmental protection; pharmacy; industries such as fruit drink; usually need to use the filter substance to filter; to dispose the assorted fine solid particle that is clipped in the fluid; filter of the prior art; the container that comprises band inlet and liquid outlet; be arranged at the chimney filter with filtering function in the container, fluid enters chimney filter through inlet, filters the back and is discharged by liquid outlet; it does not usually have the automatic discharge function; therefore, after time one length, filter residue will block up and squeeze in chimney filter; need to clean after the special shutdown dismounting; perhaps need to install specially backwashing system and clean filter residue, expended manpower; material resources have increased production cost.

The utility model content

The purpose of this utility model is to provide a kind of filter with automatic discharge function in order to overcome above-mentioned the deficiencies in the prior art.

The purpose of this utility model is achieved in that

A kind of automatic discharge filter, the container that comprises band inlet and liquid outlet, be set up in parallel the several chimney filters in container with filtering function, the import of chimney filter front end communicates with inlet, dividing plate and rear bulkhead before in container, being respectively arranged with, dividing plate and rear bulkhead and sealing and fixing were thereon before the two ends of described chimney filter were passed respectively, the back outlet place of every chimney filter is provided with and exports the cone valve of size coupling, described size coupling is meant that chimney filter exit diameter of a circle size is between cone valve upper surface circular diameter and lower surface circular diameter, cone valve is provided with the spring that is fixed in container bottom, cone valve and outlet offset and form sealing and block outlet under the effect of spring, on the chamber wall before and after described liquid outlet is arranged between the dividing plate, the wall between container bottom and the rear bulkhead is provided with slag-drip opening.

Chimney filter described in the utility model is to be made by the filtering material that has a lot of trickle filtering holes on it.

When the utility model uses, filtrate is pressed in the chimney filter from inlet under the effect of oil pump, when initial, filtrate to the pressure of chimney filter rear end cone valve less than the support force of spring to cone valve, this moment, filter was realized filtering function, filtrate is discharged by the liquid outlet on the ampuliform body wall that is arranged between two dividing plates after chimney filter filters, and filter residue remains in the chimney filter and dashed to cone valve place, chimney filter rear end; Filter residue residual quantity in the chimney filter increases gradually at leisure, make the area that is used to filter in the chimney filter reduce gradually, thereby cause the pressure of filtrate in the chimney filter to increase gradually, when filtrate to the pressure of chimney filter rear end cone valve greater than spring during to the support force of cone valve, this moment, filter was realized deslagging function, cone valve is pushed open by filtrate, and filter residue is being discharged from the chimney filter rear end under the filtrate thrust and automatically outside the slag-drip opening discharge filter; After filter residue was discharged, the area that is used in the chimney filter filter increased, and filtrate pressure reduces, and chimney filter rear end cone valve resets under spring action and pushes against and form sealing with the chimney filter rear port, proceeds to filter, and so circulation has realized the automatic discharging to filter residue.

In sum, than prior art, the utility model is owing to the automatic discharging that has realized filter residue; need not artificial the shutdown during this spline filter and clean, also need not to install backwashing system, thereby saved human and material resources; reduced production cost, its automaticity height.

Description of drawings

Fig. 1 is the utility model cross-sectional view.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

By shown in Figure 1, the automatic discharge filter of present embodiment, the container 3 that comprises band inlet 1 and liquid outlet 2, be set up in parallel the several chimney filters of making by filtering material 4 in container 3 with a lot of trickle filtering holes, chimney filter 4 front end imports 9 communicate with inlet 1, dividing plate 5 and rear bulkhead 11 before wherein being respectively arranged with in the container 3, the two ends of described chimney filter 4 are passed preceding dividing plate 5 and rear bulkhead 11 respectively and are sealingly fastened in two dividing plates 5, on 11, back outlet 10 places of every chimney filter 4 are provided with and export the cone valve 6 of 10 size couplings, cone valve 6 is provided with the spring 7 that is fixed in container 3 bottoms, cone valve 6 will export 10 sealings under the effect of spring 7, dividing plate 5 before and after described liquid outlet 2 is arranged at, on container 3 walls between 11, the wall between container 3 bottoms and the rear bulkhead 11 is provided with slag-drip opening 8.

During use, filtrate is pressed in the chimney filter 4 from inlet 2 under the effect of oil pump, when initial, filtrate is to the pressure of chimney filter 4 rear end cone valves 6 support force less than 7 pairs of cone valves 6 of spring, this moment, filter was realized filtering function, filtrate is discharged by the liquid outlet on container 3 walls that are arranged between two dividing plates 5,11 2 after chimney filter 4 filters, and filter residue remains in the chimney filter 4 and dashed to chimney filter 4 rear end cone valves 6 places; Filter residue residual quantity in the chimney filter 4 increases gradually at leisure, make the area that is used to filter in the chimney filter 4 reduce gradually, thereby cause the pressure of filtrate in the chimney filter 4 to increase gradually, when filtrate to the pressure of chimney filter 4 rear end cone valves 6 during greater than the support force of 7 pairs of cone valves 6 of spring, filter is realized deslagging function, cone valve 6 is pushed open by filtrate, and filter residue is being discharged from chimney filter 4 rear ends under the filtrate thrust and automatically outside slag-drip opening 8 discharge filters; After filter residue was discharged, the area that is used to filter in the chimney filter 4 increased, and filtrate pressure reduces, and chimney filter 4 rear end cone valves 6 reset under the effect of spring 7 and with 10 sealings of chimney filter 4 back outlet, proceed to filter, and so circulation has realized the automatic discharging to filter residue.
