Description

Filter roller inspection port

Technical Field

The utility model relates to an aquaculture equipment, specifically speaking are a drum filter for aquaculture.

Background

Drum filters are increasingly widely used for filtering sewage in aquaculture, and can play a role in microfiltration of water and filter excrement impurities larger than meshes.

The drum of the drum filter is currently a closed cylinder. The cylinder skeleton is generally made of a punching plate with a large inspection opening, a plastic cylinder, a thick iron net, namely a skeleton large net and the like. The skeleton inspection opening is small, and the width can not enter arms or tools.

Therefore, if the inside of the roller is blocked, only the whole roller can be disassembled, and the blockage can be taken out, which is very inconvenient.

Disclosure of Invention

The utility model provides a filter cylinder inspection hole, its purpose is to solve prior art's shortcoming, and it is more convenient to maintain drum filter's cylinder, and efficiency is higher.

The utility model provides a technical scheme that its technical problem adopted is:

filter cylinder inspection opening, its characterized in that:

an inspection opening is formed in a framework large net of the roller, and the cross section of the inspection opening is larger than a circle with the diameter of 20 cm; the framework is welded on the framework large net outside the edge of the inspection opening, a piece of covering net covers the inspection opening and the framework, and screws penetrate through the covering net and the framework to enable the covering net to be fixed on the framework and cover the inspection opening.

The inspection opening is square, long-strip or round.

The framework big net of the roller is also covered with a fine net with the aperture smaller than that of the framework big net, and a screw penetrates through the fine net, the covering net and the frame to fix the fine net and the covering net together.

The utility model discloses an useful part lies in:

the utility model discloses open out the local big net of big inspection opening reuse cover of skeleton big net and fix, make things convenient for hand or instrument to get into, consequently needn't disassemble the cylinder and just can stretch into arm or instrument and take out the plug.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a state diagram of the inspection hole covered by the covering net of the present invention;

fig. 2 is a view showing the state of the cover net of the present invention.

Detailed Description

In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor. In order to facilitate an understanding of the invention, the invention is described in more detail below with reference to the accompanying drawings and specific examples.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. As used in this specification, the terms "upper," "lower," "inner," "outer," "bottom," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the invention and simplicity in description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 and 2:

the drum 1 is supported on a frame 100, a geometric inspection opening 3 is formed on a framework large net 2 of the drum 1, the shape of the inspection opening 3 can be square, long strip, round and the like, and the cross section of the inspection opening 3 is larger than a circle with the diameter of 20 cm. That is, a circle with a diameter of 20cm can be completely contained at the position of the inspection opening 3, so that the arms of a general male can be extended in for maintenance work.

The inspection hole 3 is shown as a square, a frame 4 is welded on the skeleton large net 2 outside the edge of the inspection hole 3, a piece of cover net 5 is covered on the inspection hole 3 and the frame 4, and a screw 6 penetrates through the cover net 5 and the frame 4 to fix the cover net 5 on the frame 4 and shield the inspection hole 3.

In order to keep the strength of the skeleton net 2 from deforming when the hand or tool is put into maintenance, the frame 4 needs to be firmly connected to the skeleton net 2.

The skeleton large net 2 of the roller 1 is covered with a fine net (not shown in the figure) with the aperture smaller than that of the skeleton large net 2, and the fine net can be assembled and disassembled conveniently, so that the skeleton large net 2 is wrapped by the whole large fine net without refitting the fine net.

The fine mesh can also be combined with the inspection opening 3 separately, namely a screw 6 penetrates through the fine mesh, the covering mesh 5 and the frame 4 to fix the fine mesh and the covering mesh 5 together, and the fine mesh and the covering mesh 5 are taken up or lifted up like a cover directly during maintenance.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other. The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
