Description

[Detailed Description of the Invention] The present invention relates to a contact material consisting of a net pipe and a joint spacer that can be filled into an aeration tank for water treatment or the like while maintaining a constant interval.

Conventionally, when filling a net pipe into an aeration tank for water treatment, etc., there are many methods in which the net pipe is packed as is.

The disadvantage in this case is that the net pipes come in contact with each other on many surfaces, and the surface area of the contact material with which microorganisms come into contact with each other decreases due to the contact surface, and the specific surface area becomes small. Because it was easily clogged, it was inefficient and required many net pipes, making it an expensive contact material.

It is also possible to skewer the net pipes using ordinary round pipes and fill them at regular intervals, but the structure becomes complicated and the cost increases.

In the first place, it is better for contact materials such as aeration tanks to have low resistance to water flow in all directions and to have contact surfaces uniformly arranged.

Since the initial contact surface of the contact material becomes thicker due to the attachment of microorganisms and the like, and the contact area naturally increases, a network structure with intervals is ideal.

The purpose of the present invention is that a net pipe and a joint spacer with a large opening ratio can be used in combination as a contact material for water treatment aeration tanks, etc., and the surface area that microorganisms etc. come into contact with is increased. Net pipes and joints are efficient because they can maintain a constant spacing between the net pipes to prevent clogging, and the net pipes can be firmly jointed with one touch, making it easy to fill the aquarium, with low water flow resistance, and inexpensive net pipes and joints. The object of the present invention is to provide a contact material consisting of a spacer.

Hereinafter, embodiments of the present invention will be specifically described based on the drawings.

Figures 1 to 3 show the first embodiment of the present invention. Figure 1 is a plan view of a joint spacer for a net pipe, Figure 2 is a side view of a joint spacer for a net pipe, and Figure 3 is a diagram of a joint spacer for a net pipe. Fig. 3 shows a front view of the joint spacer attached to the holder.

The joint spacer S for net pipes of this embodiment is a joint spacer that can joint the net pipe N with a certain space using a contact material filled in an aeration tank for water treatment, etc. It is a joint spacer that can joint the net pipe N with a certain space. X with hole 3 to form
A net pipe engagement hole formed integrally with a plurality of Y-direction space frames 2 forming Y-direction spaces on the left and right sides of the X-direction space frame 1 and having a plurality of openings on the left and right sides of the X-direction space frame 1. 6, and the dimensions of the net pipe engagement hole 6 are made to be approximately the same as the outer diameter dimension of the net pipe N, and the engagement foot frame 4 is attached to the X direction space frame 1. A plurality of engaging pieces 5 are provided on the Y-direction space frame 2.

Here, it is better to mold the joint spacer S from a chemical-resistant, weather-resistant, and elastic resin such as polyethylene or PP.

Although the engaging leg frame 4 in this embodiment is not necessarily necessary, the engaging leg frame 4
If there is, the joint spacer S will be more stable.

When the joint spacer S for net pipes with such a structure is inserted into the net pipes N side by side,
The X-direction space frame 1, the Y-direction space frame 2, and the engaging foot frame 4 of the joint spacer S engage with the outer surface of the net pipe N, and the engaging piece 5 is inserted into the mesh 8 of the net pipe N, and the mesh line It can be attached to 7.

Here, the joint spacers S may be randomly attached to the net pipes N at appropriate intervals.

Also, if a locking piece is provided at one end of the Y-direction space frame 2 of the joint spacer S, and a hole is provided at the other end, the joint spacers S can be elastically connected to each other. Adjacent spacers S can be jointed together to firmly fix the entire contact material.

Figures 4 and 5 show a second embodiment of the present invention, with Figure 4 being a plan view when the joint spacer is fitted into the net pipe, and Figure 5 being a front view. be.

The joint spacer S for a net pipe according to this embodiment has a hole 9 also provided in the Y-direction space frame and is formed with different left and right lengths, and the other configurations and structures are the same as those of the first embodiment. It is.

As is clear from the above, according to the present invention, a net pipe and a joint spacer with a large opening ratio can be used in combination as a contact material in an aeration tank for water treatment, etc., and the net pipes can be connected to each other to prevent clogging. It is practical because it is possible to maintain a constant spacing, joint the net pipe with one touch, easily fill the aquarium, has low water flow resistance, and provides an inexpensive contact material consisting of the net pipe and joint spacer. This has a great effect.
