Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dust net mounting frame for receiving dirt used in a grease trap.
[0002]
[Prior art]
Conventional grease traps are equipped with a metal basket in a tank for storing filth.
[0003]
[Problems to be solved by the invention]
If dirt accumulates in the basket, it must be cleaned regularly. However, this cleaning operation mainly depends on human labor, and thus it takes time and effort. Therefore, it is desired to use an apparatus that can simplify the cleaning work.
[0004]
[Means for Solving the Problems]
In the first invention, four sets of rails that are slidably fitted to each other are connected to each other to form a frame in which two opposite sides are parallel, and the frame slides two parallel sides in the length direction. The waste can be freely changed in size by being moved, and is fixed with fixing means after the frame is set to a predetermined size, and the opening end of the net that receives the dust is hooked around the frame. It is a net mounting frame.
A second invention is a garbage net mounting frame according to the first invention, which employs a net that expands and contracts according to the shape and size of the frame.

[0016]
The first guide 5 and the third guide 7 can be slid with respect to the first rail 1 and the second rail 2 in the direction of arrow A shown in FIG. 3, respectively, and the second guide 6 and the fourth guide 8 are also It can be made to slide with respect to the 1st rail 1 and the 2nd rail 2 in the arrow A direction shown in FIG.
[0017]
The fifth guide 25 and the seventh guide 27 can be slid with respect to the third rail 3 and the fourth rail 4 in the direction of arrow B shown in FIG. 3, respectively, and the sixth guide 26 and the eighth guide 28 are also It can be made to slide with respect to the 3rd rail 3 and the 4th rail 4 in the arrow B direction shown in FIG.
[0018]
As shown in FIG. 6, a partition 54 is inserted in the grease trap 200. As shown in FIG. 7, one side of the partition 54 is partition guides 51a and 51b fixed to the inner wall 53, and the other side is a partition. The partition 51 is detachably attached to the grease trap 200. The partition 54 is sandwiched between the guides 51c and 51d.
[0019]
As shown in FIG. 7, flanges 53a, 53b, 54b are fixed to the inner wall 53 of the grease trap 200, and a flange 54a is fixed to the partition 54 with the height of the upper surface thereof matched.
[0020]
The garbage net mounting frame 100 can change the size of the rectangle of FIG. 1 by sliding the guides with respect to the rails, and is attached to the upper surfaces of the flanges 53a, 53b, 54a and 54b shown in FIG. 3, the lower surfaces 105 to 108 shown in FIG. 3 are landed, and the dust net mounting frame 100 is mounted in the grease trap 200.
[0021]
Each guide can be adjusted by sliding in the directions of arrows A and B in FIG. 3 according to the shape and size of the space partitioned by the inner wall 53 and the partition 54 of the grease trap 200.
[0022]
After adjusting each guide according to the size divided by the inner wall 53 and the partition 54 of the grease trap 200, the upper flanges 1a and 1b of the first rail 1 and the first guide 5 shown in FIG. 1 The guide 5 is engaged with the flanges 5a and 5b so that it cannot slide. Each rail and each guide are caulked in the same manner as the first rail 1 and the first guide 5 so that they cannot slide.
[0023]
When the caulking is fixed at a position where the size of the space 100a (FIG. 1) is minimized without sliding each guide with respect to each rail, the mesh size is 0.5 to 4 mm (preferably 2 mm). The opening edge of the mesh bag 52 (FIG. 5) is hooked on both ends 91a and 91b of the first rail 1 and both ends 92a and 92b of the second rail 2 shown in FIG. receive.
[0024]
When each guide or one of the guides is slid with respect to each rail and the position of the guide is fixed by caulking each rail, the opening edge of the mesh bag is located at the upper right as viewed in FIG. The end 95, the right lower end 96 of the second guide 6, the left upper end 97 of the third guide 7, and the left lower end 98 of the fourth guide 8 are hooked.
[0025]
As filth accumulates in the mesh bag, the opening edge of the mesh bag is dragged toward the space 100a, but is caught by the claws 1e, 1f, 2e, 2f, 3a to 3e, and 4a to 4e, and is firmly held.
[0026]
When the dirt accumulates in the mesh bag and becomes clogged, the handles 20a and 20b (FIG. 1) are held, and the mesh bag (not shown) is removed from the grease trap together with the dust net mounting frame 100. When the bottom of the mesh bag touches the ground, filth may come out from the opening of the mesh bag. The legs 32 and 33 shown in FIG. 4 and the legs 31 and 34 shown in FIG. It has a function that prevents the bottom of the mesh bag from touching the ground when placed on flat ground. The lengths of the legs 31 to 34 in the vertical direction as viewed in FIGS. 4 and 5 are set according to the accumulation amount of filth contained in the net bag.
[0027]
Each rail and each guide may be bonded with an adhesive other than caulking, or may be welded if made of steel, or may be fixed with a bolt and nut.
[0028]
【The invention's effect】
It is possible to easily manufacture a garbage net mounting frame corresponding to various shapes and sizes of grease traps with a small number of members.
[0029]
Since the shape and size of the frame can be changed according to the shape and size of the grease trap, mass production is easy and economical.
[0030]
If a stretchable net is adopted, it is possible to deal with garbage net mounting frames of different sizes, and it is not necessary to prepare a non-stretchable net that matches the size of the frame each time.
