Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to a wastewater treatment tank which is installed on the floor of a kitchen facility or the like and treats wastewater from the kitchen facility.

2. Description of the Related Art A wastewater treatment tank which has a box-shaped inner and outer tank body having a bottom plate and a side plate and which is provided on a floor of a kitchen facility or the like with an insulating wall interposed, and which treats wastewater from the kitchen facility is already known. .

In such a wastewater treatment tank, both the box-shaped inner and outer tank bodies are manufactured in advance as an integrated body, and a bolt is attached to the outside of the side plate of the inner tank body to form a heat insulation wall having a predetermined size. Attach a heat insulating wall to the inner tank body by making a hole in the position facing the bolt, inserting a bolt into this hole and joining the joints of each heat insulating wall with heat resistant adhesive or nails, and then to the outer tank body. It was constructed by bonding.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, in the waste water treatment tank as described above, when the heat insulating wall is attached to the inner tank body, a bolt hole is accurately formed at a position facing the bolt, and after inserting the bolt into the hole, Since it is necessary to join the joints of the heat insulation walls, it is difficult to work at the construction site and the construction period is long.In addition, the inner and outer tanks, heat insulation walls, etc. are pre-molded in one piece, so during the installation work or the year of use. There was a problem that if part of it was damaged over the course of the month, the entire part had to be replaced.

Therefore, an object of this invention is to solve the problems of the conventional wastewater treatment tank as described above, to facilitate the whole manufacturing work including the installation of the heat insulation wall, and to shorten the construction period. It is an object of the present invention to provide a wastewater treatment tank which does not need to be entirely replaced by replacing only a part having a damaged part when the part is damaged.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention comprises a heat insulating wall integrally formed in advance, and the outer tank body has a bottom plate and a side plate which are separately formed. The inner tank body is fitted inside the box-shaped heat insulating wall, the side plates of the outer tank body are attached to the outer surface of the heat insulating wall, and the side plates are detachably connected by connecting members, and the bottom plate is attached to this. The outer tub body is formed by surrounding it with a cage-shaped support member, and the upper end of the vertically connecting pillar of this support member is detachably connected to the flange of the outer tub body. .

In the wastewater treatment tank of the present invention as described above, the inner tank body is inserted into the box-shaped heat insulating wall body, and this heat insulating wall is surrounded by the bottom plate and the side plate of the outer tank body, and each side plate can be attached and detached by the connecting member. They are connected to each other, and the whole is housed in the cage-shaped supporting member, and the vertically connecting columns of the cage-shaped supporting member are detachably coupled to the flange of the outer tank body.

Embodiment In the embodiment of the present invention shown in the drawings, reference numeral 1 denotes a box-shaped inner tank body, which has an outwardly projecting flange on an upper portion of a tank body 2 composed of a bottom plate and a side plate, and a plurality of flanges are provided on this flange. A connecting plate 4 is attached, and a connecting hole 5 is provided in the connecting plate 4.

Reference numeral 7 denotes a box-shaped outer tank body, which has one bottom plate 8 and four side plates 9 formed separately as shown in FIG. 1 before assembly, and 10 has adjacent side plates 9 at both side edges thereof. 4 shows four angled connecting members to be connected (only three are shown in FIG. 1). Then, the side plate 9 and the connecting member 10 are provided with through holes 11 and 12 for mounting a coupling fitting for connecting both members.

Reference numeral 14 denotes a heat insulating wall interposed between the inner and outer tank bodies 1 and 7, and this heat insulating wall 14 has one bottom plate 15 and four side plates 16 preformed, and the joints thereof are heat-resistant adhesive or nails. It is constructed by joining with.

Reference numeral 18 denotes a cage-shaped supporting member, and the supporting member 18 is a bottom plate 8
It has a lateral support portion 19 for support and a connecting column 20 which is established upward from both ends thereof, and a connecting portion 21 at the upper end of the connecting column 20.
A connecting hole 22 is provided at a position facing the connecting plate 4 of the inner tank body 1 and at a position corresponding to the connecting hole 5.

When assembling the wastewater treatment tank by the above-mentioned thing, each side of the inner tank body 1 configured in advance is attached to the outer periphery of the heat insulating wall 14 having the same structure, and the side plate 9 of the outer tank body 7 is attached. The side plate 9 is detachably connected by the connecting member 10, and the thus constructed one is housed in the supporting member 18 so as to be mounted on the bottom plate 8 placed on the supporting portion 19 of the supporting member 18, and The connecting portion 21 of the connecting column 20 of the support member 18 is detachably connected to the inner tank body 1 by a connecting tool inserted into the connecting holes 5 and 22.

In addition, the drainage pipe 2 shown in Figs.
Although 3 is provided, it is omitted in FIG.

In this way, the entire configuration is completed, and this is installed in the opening provided in the floor 25 of the building, as shown in FIGS. 1 to 4, in the same manner as the conventional wastewater treatment tank of this type, 26 indicates a manhole.

In such a case, for example, when the bottom plate 8 or the side plate 9 of the outer tank body 7 is damaged, the entire body is taken out from the opening of the floor 25, and the support member 18 and the inner tank body 1 are connected. And the side plate 9 and the connecting member 10 are released from each other, the parts are disassembled into the state shown in FIG. 1, only the damaged parts are replaced, and the parts are reassembled. Install it like.

Advantageous Effects of Invention The present invention is as described above, in which the inner tank body and the heat insulating wall are integrally formed in advance as in the conventional case, the outer tank body is formed with the bottom plate and the side plate separately, and each side plate is connected by the connecting member. Since it is detachably connected to the inner tank body and the heat insulating wall by a supporting member, when attaching the heat insulating wall to the inner tank body, bolts are attached to the inner tank body and heat insulation is performed. It is not necessary to provide a through hole for penetrating the bolt on the wall to connect the two, and therefore the assembling process is extremely simple, and the entire structure can be achieved very easily at the manufacturing factory or construction site. If a part of the outer tub body is damaged, the whole part can be disassembled and replaced with a new one in a simple procedure. The effect is that it can be stretched.
