A stepped oil separation tank

Abstract

This application discloses a stepped grease trap, relating to the field of grease traps, comprising multiple equally arranged storage tanks. Each storage tank has an internal filtration mechanism, a snap-fit ​​mechanism on one side, and equally distributed tank covers on the top. The snap-fit ​​mechanism includes an inlet pipe and an outlet pipe respectively fixedly installed on both sides of the storage tank. This invention uses the snap-fit ​​mechanism to quickly connect the inlet and outlet pipes, thereby connecting two storage tanks. The lower and upper arc-shaped snap-fit ​​plates are fully snapped onto the outer sides of the adjacent first and second annular plates. Flipping the T-shaped rod upwards causes the J-shaped snap-fit ​​plate to flip, snapping it onto a limiting shaft. Under the action of a spring, the limiting ring moves, pressing the J-shaped snap-fit ​​plate onto the limiting shaft, thus fixing the upper and lower arc-shaped snap-fit ​​plates, thereby quickly connecting the inlet and outlet pipes. This invention provides a quick connection between the inlet and outlet pipes.

Description

Technical Field

[0001] This utility model relates to the field of grease trap technology, and in particular to a stepped grease trap. Background Technology

[0002] In the process of rapid global industrialization and urbanization, the problem of oily wastewater discharge is becoming increasingly serious. Oily wastewater mainly comes from many fields such as catering, petrochemical, machinery processing, and food processing. If it is discharged directly without effective treatment, it will not only cause serious damage to the aquatic ecosystem and threaten the survival of aquatic organisms, but also cause a series of environmental problems.

[0003] Oily wastewater flows into the first stage of the grease trap from the inlet. In each stage, the wastewater is in a relatively static state, and oil droplets and water droplets separate due to their different densities. The wastewater flows through each stage in sequence, and a similar gravity separation process takes place at each stage. After separation through multiple stages, wastewater that is basically free of grease or has a very low oil content is discharged from the outlet of the grease trap.

[0004] Existing stepped grease traps have a relatively small number of isolation tanks and cannot completely separate oily wastewater. When connecting two or more grease traps, it is necessary to use a wrench to tighten several bolts, which is a rather cumbersome process. Therefore, a stepped grease trap is proposed.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 This is the first embodiment of the present utility model. This embodiment provides a stepped oil separator, which includes multiple liquid storage tanks 1 arranged in an even manner. A filter mechanism 2 is provided in the inner cavity of the liquid storage tank 1. A snap-fit ​​mechanism 3 is provided on one side of the liquid storage tank 1. The top of the liquid storage tank 1 is provided with an evenly distributed tank cover 4.

[0031] Specifically, the first liquid storage tank 1 is one-third higher than the connected second liquid storage tank 1, and the tank covers 4 are evenly placed on top of the liquid storage tank 1. Through multiple liquid storage tanks 1, the oil and water processing path can be extended, and the oil and water can be completely separated.

[0032] The snap-fit ​​mechanism 3 includes an inlet pipe 301 and an outlet pipe 302 that are respectively fixedly installed on both sides of the liquid storage tank 1. A first annular plate 303 is fixedly installed on the outer surface of the outlet pipe 302, and a second annular plate 304 is fixedly installed on the outer surface of the inlet pipe 301.

[0033] Specifically, the outlet pipe 302 is installed on one side of the liquid storage tank 1 at a position lower than the inlet pipe 301 is installed on one side of the liquid storage tank 1. The outlet pipe 302 is inserted into the inlet pipe 301, and then the first annular plate 303 is completely pressed against one side of the second annular plate 304, thereby enabling quick connection.

[0034] The locking mechanism 3 also includes an upper arc locking plate 306 and a lower arc locking plate 305. Fixing blocks 312 are symmetrically installed on the outer surfaces of the upper arc locking plate 306 and the lower arc locking plate 305. Limiting shafts 309 are fixedly connected to the opposite side of the two fixing blocks 312.

[0035] Specifically, after inserting the outlet pipe 302 into the inlet pipe 301, the first annular plate 303 is completely attached to one side of the second annular plate 304. At this time, the lower arc clamping plate 305 and the upper arc clamping plate 306 completely wrap the first annular plate 303 and the second annular plate 304. The first annular plate 303 and the second annular plate 304 are compacted and have a sealing function, which can quickly connect the outlet pipe 302 and the inlet pipe 301.

[0036] The other two fixed blocks 312 are rotatably provided with T-shaped rods 311 on opposite sides. J-shaped clamping plates 310 and limiting rings 307 are movably installed on the outer surface of the T-shaped rods 311. Springs 308 are provided at the top of the J-shaped clamping plates 310 and the limiting rings 307.

[0037] Specifically, manually pull the limiting ring 307 upward on the outer surface of the T-shaped rod 311 to move the limiting ring 307, flip the T-shaped rod 311 upward on the opposite side of the two fixing blocks 312, and lock the T-shaped rod 311 onto the outer surface of the limiting shaft 309. Under the action of the spring 308, push the limiting ring 307 downward on the outer surface of the T-shaped rod 311 to fix the J-shaped clamping plate 310, thereby connecting the upper arc clamping plate 306 and the lower arc clamping plate 305, and then connecting the water inlet pipe 301 and the water outlet pipe 302.

[0038] The water outlet pipe 302 is adapted to the water inlet pipe 301. The upper arc plate 306 is hinged to the top of the lower arc plate 305. The J-shaped plate 310 is movably engaged with the outer surface of the limiting shaft 309. The limiting ring 307 is fixedly connected to the top of the J-shaped plate 310.

[0039] Furthermore, the lower arc plate 305 and the upper arc plate 306 are completely locked onto the outer sides of the adjacent first annular plate 303 and second annular plate 304. The T-shaped rod 311 is flipped upward, causing the J-shaped plate 310 to flip. The J-shaped plate 310 slides upward on the outer side of the T-shaped rod 311. Then, the J-shaped plate 310 is fitted and locked onto the limiting shaft 309. At this time, under the action of the spring 308, the limiting ring 307 is pushed to move, thereby pressing the J-shaped plate 310 onto the limiting shaft 309 and fixing the upper arc plate 306 and the lower arc plate 305, thereby quickly connecting the water inlet pipe 301 and the water outlet pipe 302.

[0040] Example 2

[0041] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a filter mechanism 2 capable of filtering oil and water containing impurities.

[0042] The filtration mechanism 2 includes an upper baffle 201 and a lower baffle 202 symmetrically installed on the inner surface of the liquid storage tank 1. A perforated plate 204 is fixedly connected to the inner surface of the liquid storage tank 1, and a collection basket 205 is movably installed inside the perforated plate 204.

[0043] Specifically, the oil and water containing impurities flow into the collection basket 205. Under the action of the collection basket 205, the impurities are collected. After the basket is full, the collection basket 205 is lifted out of the perforated plate 204 and the collected impurities are disposed of in a centralized manner. Under the action of the lower baffle 202, the flow rate of oil and water at the bottom of the perforated plate 204 is slowed down. Since the density of oil is less than that of water, the oil in the oil-water mixture moves slowly upward.

[0044] A U-shaped plate 203 is fixedly installed on one side of the inner surface of the liquid storage tank 1, and an air outlet pipe 206 is fixedly installed at the bottom of the inner surface of the liquid storage tank 1.

[0045] Specifically, the U-shaped plate 203 can block the uppermost layer of oil in the oil-water mixture from flowing out. When the oil-water mixture is slowly vented in the vent pipe 206, the air bubbles can increase the upward flow speed of the oil droplets in the oil-water mixture that are flowing upward more slowly.

[0046] The inlet of the vent pipe 206 passes through the perforated plate 204 and is located at the bottom of the cover 4. The outlet of the vent pipe 206 is divided into eight branches and is evenly distributed on the bottom of the inner surface of the liquid storage tank 1.

[0047] Furthermore, the oil and water containing impurities flow into the collection basket 205. Under the action of the collection basket 205, the impurities are collected. After the basket is full, the collection basket 205 is lifted out of the perforated plate 204 and the impurities are processed in a concentrated manner. Under the action of the lower baffle 202, the flow speed of the oil and water at the bottom of the perforated plate 204 is slowed down. The upper baffle 201 blocks the oil surface of each compartment. The oil and water are then processed through multiple storage tanks 1.

[0048] Working principle: When multiple liquid storage tanks 1 need to be connected, insert the outlet pipe 302 on one side of liquid storage tank 1 into the inlet pipe 301 of another liquid storage tank 1, so that the first annular plate 303 is completely attached to one side of the second annular plate 304. Then, completely lock the lower arc clamping plate 305 and the upper arc clamping plate 306 onto the outside of the attached first annular plate 303 and second annular plate 304. Flip the T-shaped rod 311 upwards, causing the J-shaped clamping plate 310 to flip, thus securing the J-shaped clamping plate 310 on the T-shaped rod. Slide the outer side of 311 upwards, and then fit the J-shaped clamping plate 310 onto the limiting shaft 309. At this time, under the action of the spring 308, push the limiting ring 307 to move, thereby pressing the J-shaped clamping plate 310 onto the limiting shaft 309, fixing the upper arc clamping plate 306 and the lower arc clamping plate 305, thereby quickly connecting the water inlet pipe 301 and the water outlet pipe 302, thus connecting the two liquid storage tanks 1. Open the top cover 4 of the liquid storage tank 1 and insert the air pipe at the output end of the air pump into the... The vent pipe 206 extends to one end above the perforated plate 204. The air pump is a conventional structure, identical to existing publicly disclosed designs. It slowly discharges gas from the vent pipe 206 located at the bottom of the inner surface of the storage tank 1. Oil and water containing impurities flow into the storage tank 1 from the inlet pipe 301. Impurities are collected by the collection basket 205, and the oil and water fall below the collection basket 205. The upper baffle 201 blocks the oil surface, and the lower baffle 202... The flow rate of the oil-water mixture is blocked. When the vent pipe 206 vents the oil-water mixture, the oil droplets that float slowly in the oil-water mixture are accelerated to increase their floating speed. When the oil-water mixture flows into the compartment where the U-shaped plate 203 is located, the oil on its surface is reduced compared to the first compartment. Finally, the water mixed with less oil flows out from the water outlet pipe 302 and settles again. After settling in the three liquid storage tanks 1, the oil and impurities in the oil-water mixture containing impurities are completely removed, and finally the water is discharged.
