JP2002161577A - Residual collecting device in grease interceptor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such a problem that a drain pipe at the exit side of a grease interceptor is clogged sometimes due to the troublesome works although oil and fats stuck to a mesh wire or the like must be frequently cleaned since the area of passing holes of the residual cage is fixed and easy to clog without cleaning and the residual is apt to overflow from the residual cage and flow out to the second or the following stage because the installation position of the residual cage is near to the drain water face level and the stainless steel own weight additional to the residual weight is considerably large in a conventional residual interceptor, and hence, it is hard to lift up the cage in collection and hence, the cage is apt to be left as it is. And the reverse condition causes clogging of the drain pipe at the grease interceptor exit side and enlargement of burden of a storage tank. SOLUTION: The residual interceptor is used for collecting residual mixed in drain in the vicinity of the inflow section into a grease interceptor. A fine and extensible net is set to a grease interceptor instead of a conventional residual cage to impart a function to catch even fine residual and removal is facilitated by making use of an adhesive characteristic brought by match of respective meshes of a facial fastener and the net.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for collecting and collecting residues mixed in wastewater, which is a method for replacing a conventional wire mesh or a residue basket made of perforated metal. The present invention relates to a device which has a function of attaching a net having fine eyes and high elasticity and having a function of collecting even fine residues, and further utilizing a bonding property of a mesh of a hook-and-loop fastener and a nylon net to facilitate attachment / detachment.

[0002]

2. Description of the Related Art As shown in FIG. 12, waste water from a kitchen or the like passes through a drain (f) (or drain pipe) and first enters a residue basket (a) from an inlet of a grease interceptor. Residue basket (a)
Is made of stainless steel wire mesh or punched metal of about 6 mesh. Large residues can be recovered by lifting the basket, but fine residues smaller than rice grains can pass through the basket and become grease interceptor. Sludge deposited at the bottom (h)
Becomes The settled sludge must be cleaned and removed every 2 to 4 weeks, but most kitchens outsource the treatment to outside contractors because of industrial waste. Employees collect the residue by lifting the residue basket (a) at the end of each work day, but have to clean the gauze of the residue basket (a) and oils and fats attached to the punching metal part.

[0003]

As shown in FIG. 12, the location of the residue basket (a) is close to the drainage surface (i) (at a low position), and the residue collected is made of stainless steel. If the weight is added, the weight increases, and it is difficult to lift up the residue basket (a) when collecting it. Oils and fats adhering to the wire mesh and punched metal parts of the residue basket (a) need to be cleaned because they cause clogging and odor, but if there is no cleaning space in the kitchen, cleaning is very troublesome. The frequency tends to decrease gradually. Further, since the area of the through hole is constant, the residue basket (a) is clogged with the passage of time due to the adhesion of the residue and oils and fats, and the residue (a) overflows the basket and flows out to the second and subsequent tanks. Since the grease interceptor has a stainless steel or iron lid (b), there is a risk that the grease interceptor may be left unnoticed. Originally, kitchen workers should perform cleaning periodically or whenever sludge accumulation becomes severe.However, in practice, these operations tend to be neglected, and clogging of the drain pipe on the exit side of the grease interceptor tends to occur. This has led to an increase in the load on septic tanks and storage tanks.

[0004]

According to the present invention, a residue collecting net (2) is attached to the inlet of the grease interceptor instead of the conventional residue basket (a) which is one of the causes. Until now, fine residues that have permeated can be collected, and since they are attached directly to the inlet, the danger of overflow can be eliminated. Since the residue collecting net (2) has elasticity, even if the net is clogged with the residue adhering to the inner surface of the net, the net expands due to the expansion of the net itself and has a characteristic that drainage is easily drained. Further, by easily attaching and detaching the net, it is possible to reliably collect the residue by a simple operation, and it is possible to work on the original wastewater purification in which the kitchen worker performs the treatment with the effort.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, as shown in FIGS. 1 to 4, a hook-and-loop fastener (1.
a, 1. b) is installed, and a residue collecting net (2) composed of a fine-mesh nylon braided material is attached. The net is clogged with the residue attached to the inner wall as the residue is collected, but the net expands due to the water pressure inside, and the eyes permeate and the moisture permeates.
Therefore, only the residues can be efficiently collected for a long time without worrying about overflow.

[0006] When the residues are sufficiently collected in the net (2), the net (2) is connected to the hook-and-loop fastener fixture (1.a,
1. b), remove water and collect and dispose of it as garbage.
b) Attach a new net (2).

[0007] By utilizing the adhesive property of the hook-and-loop fastener (3) as a means for attaching the net, anyone can attach and remove the fastener by a simple operation. Since the compatibility of the mesh of the nylon mesh with the residue collection net (2) and the hook-and-loop fastener (3) matches, the net can be strongly held against the force in the inflow direction, and the net can be held vertically (in the removal direction). ) Has the property of being easily peeled off.
When the net (2) is mounted, the net can be mounted simply by covering the residue collecting net (2) with the hook-and-loop fastener (3) and pressing lightly from above.

[0008] The replacement cycle of the residue collection net (2) depends on the amount of residue and the quality of residue (oil content,
Scale, etc.), but 300 visits a day
It is about three days in the average cafeteria for humans, which is a significant improvement in work compared to the conventional method of pulling up and cleaning the residue basket every day.
