[Problems that the device is trying to solve]

 This had the following drawbacks. (A) The method of opening the lid plate of the container body and removing the contaminants inside with a ladle requires a great deal of labor for opening and closing the lid plate and discharging the contaminants, and the disposal of the contaminants is simple. Can not. Even in the method of removing with a vacuum device, opening and closing of the lid plate and installation of the vacuum device cannot be easily performed, and this method also requires a great deal of labor. (B) Even in the method of Utility Model Publication 62-35738, it takes a lot of labor to open and close the lid plate 3a, and the contact material 16 is placed in the polluted liquid, so that it is taken out of the container body 2 '. At this time, the contaminated liquid inside is accompanied, and the treatment is confused, and at the same time, the malodor inside the container body 2 ′ leaks to the outside to cause discomfort. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 (A) The drainage pump 6 is installed in the oil / water separation chamber S of the container body 2, and a suction chamber 6a is attached to the suction part to partition it from the external oil / water separation chamber S. A suction pipe 6a 'having a suction port i which is lowered by a height h of a contaminated liquid such as oil is connected to the suction chamber 6a. A discharge pipe 6b is connected to the discharge part j of the drainage pump 6, and is connected to a contaminant discharge port 6b ″ through a contaminant discharge amount control valve 6b ′ installed outside the container body 2. (b) Drainage pump The power cable 6c of 6 is connected to a drain pump operating panel 14 installed outside the container body 2. This drain pump operating panel 14 is provided with an electromagnetic switch 14a and a time switch 14b, and the drain pump 6 is installed. Periodic constant time automatic operation and manual operation shall be possible. (C) A reservoir 11 is installed under the polluted liquid discharge port 6b ″, and a drainage port 15 for filtered water is installed inside the reservoir 11. The drainage port 15 and the outflow chamber T of the container body 2 are connected by a filtered water discharge pipe 15a. Inside the reservoir 11, a filter medium storage basket 12 made of a mesh plate is installed, and a filter medium 13 for leaving oil and the like in the polluted liquid therein is installed therein. The present invention is a grease trap having the above configuration.

[0005]

[Effect of device]

 In the oil / water separation chamber S, oil and the like contained in the contaminated liquid that has passed through the contaminant removing basket 7 floats above the oil and water. When the water level of the container body 2 is in a steady state, the drainage pump 6 is operated for a fixed time, so that the contaminated liquid having a liquid height h containing oil and the like is sucked from the suction port i of the suction pipe 6a '. ', The suction chamber 6a, the discharge pipe 6b, the contaminant discharge amount control valve 6b', and the contaminant discharge port 6b ", and the filter medium in the filter medium storage basket 12 installed inside the reservoir 11. When the polluted liquid passes through the filter medium 13, the oil and the like remain inside the filter medium 13 and only the water passes through the mesh of the filter medium storage basket 12 and the reservoir 11. It is discharged to the discharge chamber T of the container main body 2 through the drainage port 15 installed at the bottom and the discharge pipe 15a.The residue in the filter medium 13 is regularly removed and the filtration efficiency is lowered by long-term use. The filter medium 13 is replaced regularly. The operating time of 6 is set by the time switch 14b in the drainage pump operating panel 14 after adjusting the pollutant discharge amount control valve 6b ', whereby the lid plate 3a is opened / closed for removing oil and the like in the pollutant. Is unnecessary, and the oil and the like remaining in the filter material 13 has no water content, and therefore can be easily removed and treated.

A suction pipe 6a having a suction port i having a height h lower than that of a contaminant such as oil is connected to the chamber 6a. A discharge pipe 6b is connected to the discharge part j of the drainage pump 6, and is connected to the contaminant discharge port 6b ″ through a contaminant discharge amount control valve 6b ′ installed outside the container body 2. (b) Drainage pump The power cable 6c of 6 is connected to the drainage pump operating panel 14 installed outside the container body 2. The drainage pump operating panel 14 is provided with an electromagnetic switch 14a and a time switch 14b, and the drainage pump 6 is installed. It shall be possible to perform periodic constant-time automatic operation and manual operation. (C) A reservoir 11 is installed under the contaminated liquid discharge port 6b ″, and a drainage port 15 for filtered water is installed inside the reservoir 11. The water drainage port 15 and the outflow chamber T of the container body 2 are connected by a filtered water discharge pipe 15a. A filter medium storage basket 12 made of a mesh plate is installed inside the reservoir 11, and oil or the like in the contaminated liquid remains inside. The filter medium 13 is installed. (D) In the above structure, when the water level of the container body 2 is in a steady state, the drainage pump 6 is operated for a fixed time so that the liquid level h containing oil or the like is increased from the suction port i of the suction pipe 6a '. The filter medium installed inside the reservoir 11 after the contaminated liquid passes through the suction pipe 6a ′, the suction chamber 6a, the discharge pipe 6b, the contaminated liquid discharge amount control valve 6b ′ and the contaminated liquid discharge port 6b ″. It is discharged into the filter medium 13 in the storage basket 12. When the contaminated liquid passes through the filter medium 13, its oil content and the like remains inside, and only water passes through the filter medium storage basket 12. Is discharged to the discharge chamber T of the container main body 2 through the mesh of the container, the drainage port 15 installed at the bottom of the storage box 11, and the discharge pipe 15a. The filter media 13 whose filtration efficiency has decreased due to The operating time of the drainage pump 6 is set by the time switch 14b in the drainage pump operation panel 14 after adjusting the pollutant discharge amount control valve 6b '. 5a and the discharge pipe 5 discharge the product to the outside of the container body 2.
