Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a grease trap used in kitchen drainage, food and meat factories, machinery parts hardening factories, etc.

(Prior art) Conventionally, to collect oil and fat from the grease trap, the top cover is opened and the oil is scooped out periodically from the top of the tank using a ladle, or a dam is placed in a part of the oil separation chamber for overflow. There is a system in which the overflow is collected from the dam.

(Problems that the invention aims to solve) The former method of using a ladle in the above work is very laborious because it requires manual labor, whereas the method of overflowing causes a large amount of water other than oil and fat to be produced due to fluctuations in the amount of sewage flowing in. There is a problem that the oil and fat recovery efficiency is not constant because the oil is sometimes taken out.

The present invention aims to solve the above problems.

(Means to solve the problem) The configuration of the present invention will be explained based on the drawings.

Figure 1 is a plan view with the upper cover of the rear half broken away, Figure 2 is a longitudinal sectional view of the same, Figure 3 is a side view of the same, and Figure 4 is an enlarged detail of the oil and fat collection section. It is a diagram.

1 is the apparatus main body, 2 is a polluted water inflow pipe, 3 is a basket, 4a, 4b and 5a, 5b are guide plates and partition plates for dividing the interior into basket chamber A, fat separation chamber B, and trap chamber C; 6 is the trap body, 7 is the outflow pipe, 8, 8', 8''... is the cover plate,
Reference numerals 9 and 9' are baffle plates, and their construction is the same as that of the conventional one.

In the present invention, in the above-mentioned structure, an oil and fat collecting disk is disposed in a part of the oil and fat separation chamber B and trap chamber C so as to rotate at all times, and this will be explained below.

11 and 11' are bridge rods installed between the front wall 1a and the rear wall 1b in the upper part of the device main body,
A motor (not shown) is connected to the bridge rods 11 and 11'.
Support legs 12a, 12b, 1 of the case 12 with built-in
2'a and 12'b are attached, and a shaft 13 driven by the motor is provided in a relationship that is orthogonal to each other between the bridge rods 11 and 11' at approximately the center of the room. 14' is a bearing for this purpose.

Therefore, the shaft 13 held between the bearings 14 and 14'
A plurality of disks 15, 15', 15'' are placed at appropriate intervals within the chamber, and about 1/3 of their diameter is immersed perpendicularly to the liquid water level in the tank. 2 in the chamber and 1 in the chamber c).
16 is a chain ring provided at the end of the shaft 13, 17 is a chain connected to the drive side of the motor, and each disc 15, 15', 15''... is slowly rotated by the drive of the motor. It is becoming more and more common.

Reference numeral 18 denotes a collecting device for collecting oil deposited on the front and back surfaces of the disks by rotation of each of the disks 15, 15', 15'', and includes an oil receiver equipped with a scraping blade. Specifically, as shown in Fig. 4, the oil receiver 19 has a front wall f open and about 1/3 of the discs 15, 15', 15''... on the bottom side. Slits 20a, 20b that can be inserted,
20c... is bored, and the rear wall has a notch 21.
The supporting legs 22, 22'
The slits 20a, 20b, 20c, .

Therefore, each slit 20a, 20b, 20c
. . . is a disk 1 in which elastic tongues 23, 23 made of rubber or the like are attached in a V-shape to the groove edges in the opposing longitudinal direction, and the tip edges are in constant contact with the front and back surfaces of the disk.
5, 15', 15'', . . . by rotating in the direction of arrow A, the oil and fat deposited on the front and back surfaces are removed.

Reference numeral 24 denotes an oil tank located at the rear of the oil receiver 19, and in the illustrated example, the notch 21 of the oil tank is located at a position that slightly enters the inside of the opening 24a, and there are holes at both ends of the opening 24a. Wing plates 25, 25
are attached so as to be locked on the bridge rods 11, 11', and handles 26, 26 are attached to both ends facing upward for convenient removal.

(Function) The present invention has the above-mentioned configuration, and the discs 15, 15', 15'' are constantly or intermittently rotated in the direction of arrow A by the drive of the motor, and thereby the chamber B and the chamber The fat S floating on the liquid surface in C adheres to each rotating disk 15, 15', 15'', which is immersed in the liquid surface by about 1/3, and moves upward. However, these adhered fats are scraped off into the oil pan 19 by coming into contact with the tongues 23, 23 that roll downward, and are thus scraped into the oil pan 19. The oil and fat that is removed is stored in the oil tank 24 through the notch 21. In anticipation of the oil tank 24 becoming full, the lid plate 8' is periodically opened to allow the oil to be taken out to the outside.At this time, a lamp lights up to indicate that a certain amount of oil is stored in the oil tank 24. It is also possible to notify the user by issuing an alarm.

The liquid from which the oil and fat content has been removed is stored in the trap body 6.
It flows into the main body through the opening 6a and is discharged to the outside via the outflow pipe 7.

(Effects of the invention) As mentioned above, the present invention rotates the disk in a direction perpendicular to the liquid surface while immersing a certain area of the disk, so that oil and fat are constantly attached to both sides of the disk and then lifted. Since the particles are scraped upward, efficient collection is achieved.

Furthermore, the collection work is automatically performed by a motor and does not require any human power, contributing to labor savings.
