Abstract

The utility model provides a pretreatment device for aquaculture sewage, which effectively solves the problems that in the prior art, a filter screen needs to be cleaned frequently, the filtering effect is not guaranteed, and the filter screen is not convenient to replace; the technical scheme includes that the device comprises a cylindrical shell which is inclined and has an opening at the left end, the left end of the shell is lower than the right end, a feed inlet is formed in the upper side of the middle of the shell, a first flange is fixed at the left end of the shell, a cylindrical screen which is coaxial with the shell and has a left opening is arranged in the shell, a second flange is arranged at the left end of the screen, the first flange and the second flange are fixed together through a plurality of screws, a water outlet is formed at the left end of the screen, an annular interval is formed between the shell and the screen, a spiral auger capable of rotating actively is arranged in the annular interval, and a discharge outlet; the utility model discloses the structure is ingenious, and compact structure can realize self-cleaning to adopt the outside to filter to the filter screen center, the space of filterable space and the ejection of compact is comparatively independent, conveniently changes the filter screen.

Description

Breed sewage pretreatment device

Technical Field

The utility model relates to a aquaculture sewage treatment plant technical field, especially breed sewage pretreatment device.

Background

When the cultivation sewage is treated, large-particle objects in the sewage need to be separated firstly, and then the cultivation sewage is further treated. Divide into two big categories among the prior art, one is traditional screen cloth filters, and this kind of mode needs frequent change or clearance to the screen cloth, and it is secondly the screen cloth that adopts helical blade and casing form filters, and sewage gets into from the filter screen center, and the large granule is detained in the tube-shape screen cloth, and most moisture flows out from the lateral wall of screen cloth, but the not good condition of filter effect appears very easily to this kind of equipment to the filter screen has a plurality of fix with screws in the frame, is difficult to change the filter screen.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a breed sewage pretreatment device, the effectual filter screen that has solved among the prior art needs frequent clearance, filter effect do not guarantee, the problem of the change filter screen of being not convenient for.

The technical scheme who its solve is, including the cylindrical casing of slope form and left end open-ended, the casing left end is less than the right-hand member, there is the feed inlet casing middle part upside, be fixed with first ring flange on the casing left end, there is coaxial and the cylindrical screen cloth of opening left with the casing in the casing, the screen cloth left end has the second ring flange, first ring flange is in the same place through a plurality of fix with screws with the second ring flange, the screen cloth left end has the delivery port, there is annular interval between casing and the screen cloth, there is the spiral auger that can initiatively rotate in the annular interval, there is the discharge gate casing right-hand member downside.

The utility model discloses the structure is ingenious, and compact structure can realize self-cleaning to adopt the outside to filter to the filter screen center, the space of filterable space and the ejection of compact is comparatively independent, conveniently changes the filter screen.

Fig. 2 is a schematic view of the housing structure of the present invention.

Fig. 3 is a schematic view of the connection between the spiral auger and the circular plate of the present invention.

Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

By figure 1 to figure 3, the utility model discloses a slope form and left end open-ended

cylindrical shell

1, 1 left end of casing is less than the right-hand member, there is feed inlet 2 casing 1 middle part upside, be fixed with first ring flange 3 on the 1 left end of casing, there is cylindrical screen cloth 4 left with 1 coaxial and opening of casing in the casing 1, screen cloth 4 left end has second ring flange 5, first ring flange 3 is in the same place through a plurality of fix with screws with second ring flange 5, screen cloth 4 left end has delivery port 6, there is annular interval between casing 1 and the screen cloth 4, have ability initiative pivoted spiral auger 7 in the annular interval, there is the discharge gate casing 1 right-hand member downside.

In order to realize the active rotation of the spiral angle, a circular plate 8 is fixed at the right end of the spiral auger 7, a motor 9 is connected to the circular plate 8, and the motor 9 is fixed at the right end of the shell 1.

A horizontal bottom plate 10 is arranged below the shell 1, and the bottom plate 10 and the shell 1 are fixed together through a plurality of support rods 11.

It should be noted that it is preferable to install a seal ring on the outer circumferential surface of the circular plate 8 to prevent leakage.

During the use, starter motor 9 pours sewage into it from feed inlet 2, and motor 9 drives spiral auger 7 and rotates, and the large granule impurity in the sewage is stayed in the cavity that screen cloth 4 and casing 1 are constituteed, and moisture enters into 4 intracavity of screen cloth and flows out from delivery port 6, and at this in-process, promote filtration efficiency, at spiral auger 7 rotation in-process, large granule impurity is upwards concentrated and is discharged from the discharge gate, and spiral auger 7 is different clears up screen cloth 4 surface.

The utility model discloses the structure is ingenious, can realize self-cleaning to adopt the outside to filter to the filter screen center, the space of filterable space and the ejection of compact is comparatively independent, conveniently changes the filter screen.
