Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grease trap used in kitchen drainage, a food and meat factory, a machine parts hardening factory, and so on.

[0002]

[Prior art]

 As a conventional grease trap, which is characterized in that floor surface wastewater is directly introduced on the spot, there is known the public utility model Showa 63-161989. In the above description, B of FIG. 1 is a vertical cross-sectional view of the structure of the grease trap in use, and A of FIG. 1 is a plan view of the grease trap. The lid plate 3'formed with S is installed so as to be in the same horizontal plane, and the inclined bottom plates 10a, 10b, 10c, 10d facing downward are provided between the container body 2'and the back surface of the lid plate 3 '. The funnel body 10 consisting of 11 'is installed, and the reservoir 11' is located above the basket 5'of the container body 2 ', its cross section is square-shaped, and the inner peripheral wall is a rising wall with a constant height h'. 11'a is formed, and a bowl 12 'is fitted therein to form a trap, and dirty water from above the lid plate 3'overflows from the rising wall 11'a through the bowl 12' to cause a trap. It is designed so that it flows down into the sket 5 '.

[0003]

[Problems that the device is trying to solve]

 This had the following drawbacks. (A) Since the basket 5'is installed below the drain trap, the contaminants contained in the floor sewage will be trapped between the trap 11 'and the bowl 12'. There is a risk of blockage, in which case the water flow will be obstructed and drainage from the top surface of the cover plate will not be possible. (B) If the foreign matters in the basket 5'are not frequently removed, the water flow in the container body 2'is blocked. In order to remove this, the lid plate 3 ', the bowl 12' and the funnel body 10 'must be detached and attached, which requires a great deal of labor. (C) Since the basket 5'is installed in the contaminated liquid, the contaminated liquid in the container body 2'is also accompanied when the basket 5'is taken out to remove foreign matters. At that time, the malodor inside the container body 2'is leaked to the outside to cause discomfort. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 A lid plate 3 having a large number of holes S formed only in the inflow chamber A portion of the container body 2 is installed so as to be flush with the floor 1, and a basket 5 for removing foreign matters is further placed under the lid plate 3. A reservoir 11 having a vertical cross-section and an inner peripheral wall forming a rising wall 11a having a constant height h in the center thereof is disposed at a constant height ho above the liquid surface in the container body 2 with its bottom position. The bowl 12 having a square cross section is fitted into the inner peripheral wall of the tank 11, and the waste water from the lid plate 3 is transferred to the inside of the tank 11 through the basket 5, the bowl 12 and the like. Is configured to overflow from the rising wall 11a of the container and flow down into the container body 2, and the deodorant packings 13, 13 'are provided at the joints between the container body 2 and the cover plates 3, 3 ", 3"'. , 13 ″ are installed. The present invention is a grease trap having the above configuration.

[0005]

[Effect of device]

 Sewage during floor cleaning can be made to flow down directly from the lid plate 3 to the container body 2. The basket 5 installed along the way removes contaminants from the wastewater and is installed under the water. It prevents the water flow from being obstructed by the clogging of foreign substances in the trap composed of the reservoir 11 and the bowl 12. The trap prevents the malodor generated in the container body 2 from leaking to the outside. Further, the basket 5 for catching the foreign matters is above the surface of the contaminated liquid of the container body 2, and the contaminated liquid in the container 2 is not accompanied when the basket 5 is taken out. This operation can be done only by removing and attaching the cover plate 3, which is much simpler than in the past. Furthermore, at that time, the odors inside the container body 2 do not leak to the outside due to the traps installed under the water, which is hygienic and does not cause discomfort. Therefore, the defects of (a), (b) and (c) are eliminated.

[0006]

EXAMPLES Examples of the present invention will be described below, but the present invention is not limited to these examples. (A) In the present invention, the liquid level in the container body 2 is divided into chambers A, B and C by the partition plate, and the upper end surfaces of the partition plate 6b and the guide plate 6a both reach the upper edge of the container body 2. Moreover, the deodorant packing 13 'is attached to the upper part of the T-shaped piece 6b "that constitutes the handle of the partition plate 6b, and the container body 2 and the lid plates 3, 3" and 3 "' are joined to each other. , Deodorizing packing 13 is attached to the container body 2 side. Further, a packing receiving base 14 is fixed to the container body 2 at the joint between the lid plates 3 "and 3" ", and a deodorant packing 13" is adhered to the upper part thereof. (B) A lid plate 3 having a large number of holes S formed only in the inflow chamber A portion of the container body 2 is installed so as to be flush with the floor 1, and a basket 5 for removing foreign matters is further provided below the lid plate 3. A reservoir 11 having a vertical cross-section and an inner peripheral wall forming a rising wall 11a having a constant height h in the center is located at a bottom position above the liquid level in the container body 2 at a constant height ho. The bowl 12 having a square cross section is fitted into the inner wall of the reservoir 11 so that the sewage from the lid plate 3 passes through the basket 5, the bowl 12 and the like into the reservoir 11. It is configured to flow down from the rising wall 11a into the container body 2 by overflow. (C) The holes are not formed in the cover plates 3 ″, 3 ″, the handle portion T is formed in a part thereof, and the blind plate 16 is fixed to the back surface of the cover plate in that part.
