Description

Technical Field

[0001] The utility model relates to the technical field of cleaning a grease trap, in particular to a grease trap which is convenient for removing slag. Background Art

[0002] The grease trap is a wastewater pretreatment structure that uses the density difference between oil droplets and water to produce a flotation effect to remove floating oil substances in oily wastewater. The structure of the grease trap is mostly horizontal flow. The oily wastewater enters the rectangular grease trap through the water distribution tank and flows slowly in the horizontal direction. During the flow, the oil floats to the water surface and is pushed into the oil collecting pipe by the oil collecting pipe or the oil scraper installed on the surface of the tank and flows into the dewatering tank. The heavy oil and other impurities that settle in the grease trap accumulate in the sludge bucket at the bottom of the tank and enter the sludge pipe through the sludge discharge pipe. The wastewater treated by the oil trap overflows into the drainage channel and is discharged outside the tank for subsequent treatment to remove emulsified oil and other pollutants.

[0003] Grease traps are mostly built with reinforced concrete, and some are built with masonry. On a rectangular plane, they are divided into 2 to 4 grids along the direction of water flow, and the width of each grid is generally not more than 6 meters, so that the water is evenly distributed. The effective water depth does not exceed 2 meters, and the length of the grease trap is generally more than 4 times the width of each grid. Grease traps often use chain-belt oil scrapers and mud scrapers to scrape floating oil and bottom sludge respectively. Generally, a set of oil scrapers and mud scrapers are installed in each grid, and a sludge bucket is set. If a baffle is added in the middle of each grid, oil scrapers and mud scrapers are installed on both sides of the baffle, and a sludge bucket is set, it is called a two-stage grease trap, which can improve the oil removal efficiency, but the equipment increases and the energy consumption increases. If several inclined plates are added to the grease trap, the oil removal efficiency can also be improved, but the construction investment is higher. In cold areas, in order to prevent the solidification of oil products in winter, a steam pipe can be set at the bottom of the oil collecting pipe for heating. Grease traps are usually covered, and a steam pipe is installed under the cover to keep warm, prevent fire and oil volatilization, and prevent dust and sand from entering.

[0004] During the cleaning process of the existing grease trap, since most of the oil residue will be present in the filter residue basket during the oil separation process, the grease trap can be cleaned by simply lifting the filter residue basket and pouring it down. However, during the oil separation process, the oil solution will also pass through the filter tank, so that a certain amount of oil residue will remain in the filter tank, which requires multiple cleanings. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a grease trap which is convenient for removing slag.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] When the filter interception plate is reversely clamped into the interior of the oil separator by the clamping block, the slag discharge hole faces upward, and then during the processing, the oil residue will be discharged into the filter tank through the slag discharge hole.

[0014] In addition, a preferred structure is that a filter residue basket corresponds to the area directly below the water inlet at the top of the end cover, and guide plates are provided on both sides of the filter residue basket.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , a grease trap for easy slag removal, comprising a grease trap 1, an end cover 2 is arranged on the top of the grease trap 1, a lifting handle 4 is arranged on the top of the end cover 2, and a water inlet 3 is opened on one side of the top of the end cover 2;

[0023] A filter basket 6 is provided on one side of the grease trap 1, and a filter interception plate 7 is fixedly installed on one side of the filter basket 6 through a clamping block 8. An opening 18 is provided on the top of the filter interception plate 7, and a slag discharge hole 13 and a filter screen 17 are provided on the sides of the filter interception plate 7.

[0024] A partition plate 15 is disposed in the middle section of the filter interception plate 7 , and a return spring 14 is disposed around the partition plate 15 at a position away from the opening 18 .

[0025] At the same time, a filter pool 11 is arranged on one side of the filter interception plate 7 , an oil outlet box 10 is arranged on one side of the filter pool 11 , and an oil outlet port 5 is connected to the end of the oil outlet box 10 .

[0026] In addition, a depth filter 12 is disposed on the other side of the grease trap 1 , and a water outlet 16 is connected to the end of the depth filter 12 .

[0027] Furthermore, after the drawer box 9 is inserted into the opening 18 , the partition 15 will move downward until the return spring 14 at the bottom of the partition 15 is squeezed to a completely squeezed state, and the return spring 14 at the top of the partition 15 is in a tensioned state.

[0028] Moreover, when the filter interception plate 7 is reversely clamped into the interior of the oil separator 1 through the clamping block 8, the slag discharge hole 13 faces upward, and then during the processing, the oil residue will be discharged into the filter tank through the slag discharge hole 13.

[0029] The filter residue basket 6 corresponds to the bottom of the water inlet 3 at the top of the end cover 2 , and guide plates 19 are provided on both sides of the filter residue basket 6 . The guide plates 19 can effectively discharge the oil-water mixture into the filter residue basket 6 .

[0030] In this embodiment, clean water is first added to the water inlet 3 at the top of the end cover 2 , and then the water flows out through the water outlet 16 , but the oil residue cannot pass through the filter screen 17 , so the oil residue still exists in the filter residue basket 6 .

[0031] First, take out the filter interception plate 7 through the block 8, and then take out the pull-out box 9 through the opening 18. Then, insert the filter interception plate 7 into the grease trap 1 in the opposite direction through the block 8 so that the slag discharge hole 13 faces upward, and then insert the pull-out box 9 into the opening 18. After the pull-out box 9 enters the filter interception plate 7.

[0032] The partition 15 is squeezed until the partition 15 squeezes the return spring 14 at the bottom of the partition 15 to a completely squeezed state, so that the partition also completely blocks the filter screen 17.

[0033] At this time, after clean water is poured in from the water inlet 3 at the top of the end cover 2, the oil residue in the filter residue basket 6 will be discharged into the filter tank from the residue discharge hole 13. At this time, the filter residue basket 6 is disassembled, and all the oil residue is cleaned into the oil outlet box 10. The oil outlet box 10 is then taken out and can be directly dumped, so that the oil residue is completely cleaned.

[0034] In the utility model, by replacing the positions of the filter screen 17 and the residue discharge hole 13 on the filter interception plate 7, the oil residue can be discharged from different channels, so that the oil residue in the oil separator 1 can be removed more efficiently, and the filter residue basket 6 can be disassembled, so that the oil residue can be cleaned with a single cleaning.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
