Description

Technical Field

[0001] The utility model belongs to the technical field of oil-water separation, and in particular relates to a novel oil-water separation device for escalators. Background Art

[0002] The transmission mechanism of the escalator is mainly chain transmission, and the chain needs lubrication. Generally, the dripping lubricant is collected by the oil pan under indoor working conditions. However, under outdoor working conditions, due to the intrusion of rainwater, the volume of the oil pan is limited, and the oily water will overflow the escalator and enter the urban sewage official website to cause pollution. At present, the national and local governments have successively issued standards for sewage discharge, which have high requirements for the oil content in sewage, and the existing oil-water separation devices for escalators have the following problems:

[0003] For example, the Chinese patent, publication number: CN201220435368.7 "An escalator oil-water separator", only relies on the different densities of oil and water to separate by gravity, which is difficult to meet the high discharge standards of sewage. However, when there is no water flowing in, the stored oil cannot be stored in a centralized manner, which is inconvenient for maintenance personnel to clean up.

[0004] For example, the Chinese patent, publication number: CN201520183190.5 "An oil-water separator for outdoor escalators", only relies on the gravity separation of oil and water by different densities, which is difficult to meet the high discharge standards of sewage;

[0005] For example, the Chinese patent, publication number: CN201510523705.6 "An outdoor escalator oil-water separator", only relies on the different densities of oil and water to separate by gravity, which is difficult to meet the high discharge standards of sewage; due to the open structure, the oily sewage is directly flushed into the sewer, which also cannot meet the high discharge standards of sewage;

[0006] For example, the Chinese patent, publication number: CN201922023971.9 "Escalator Oil-Water Separator", only relies on the difference in oil and water density to separate by gravity. When the water volume is large, it cannot ensure effective separation, and even the oily sewage is directly flushed into the sewer, which cannot meet the high sewage discharge standards;

[0007] Therefore, a novel oil-water separation device for escalators is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] See also Figure 1-3 The utility model provides a novel oil-water separation device for escalators, comprising an oil-water separation tank 1, a velocity separation baffle 2, a gravity stratification component 3, an oil discharge pipe 4, a sewage inflow chamber 5, a first separation chamber 6, a second separation chamber 7 and a cover body 9. The oil discharge pipe 4 is connected to the oil-water separation tank 1, and the velocity separation baffle 2 and the gravity stratification component 3 are both connected to the oil-water separation tank 1. By setting the velocity separation baffle 2, the oil layered above can flow into the first separation chamber 6 through the velocity separation baffle 2;

[0025] The sewage inflow chamber 5 is arranged between the oil-water separation tank 1 and the partition, the first separation chamber 6 is arranged between the velocity separation partition 2 and the gravity stratification partition 31, and the gravity stratification partition 31 is arranged between the velocity separation partition 2 and the oil discharge pipe 4. By arranging the oil discharge pipe 4, the separated oil inside the second separation chamber 7 can be discharged through the oil discharge pipe 4;

[0026] The second separation chamber 7 is arranged between the oil drain pipe 4 and the gravity stratification partition 31. Four mounting components 8 are connected to the upper surface of the oil-water separation tank 1. The cover body 9 is arranged between the four mounting components 8. The mounting component 8 includes a mounting plate 81. The mounting plate 81 is connected to the upper surface of the oil-water separation tank 1. A through-mounting hole 82 is provided in the mounting plate 81. By setting the mounting hole 82, an external bolt can be passed through the mounting hole 82 and the device can be installed at a suitable position.

[0027] The first separation chamber 6 is connected to the second separation chamber 7 through four through grooves 32. By providing the through grooves 32, the oil in the first separation chamber 6 can flow into the second separation chamber 7 through the through grooves 32.

[0028] The height of the flow rate separation baffle 2 is higher than the height of the through groove 32 and the oil drain pipe 4, the height of the flow rate separation baffle 2 is lower than the height of the gravity stratification baffle 31, the height of the oil drain pipe 4 is lower than the height of the cover body 9 and the gravity stratification baffle 31, and the height of the oil drain pipe 4 is lower than the height of the through groove 32.

[0029] The working principle and use process of the utility model are as follows: oil and water are passed from the sewage inflow chamber 5 into the oil-water separation tank 1. Since the density of water is greater than that of oil, the oil and water flowing into the oil-water separation tank 1 are stratified, with oil on the top and water on the bottom. When the oil and water continue to be passed into the oil-water separation tank 1, the oil on the top can flow into the first separation chamber 6 from above the velocity separation baffle 2. Since the height of the velocity separation baffle 2 is higher than the height of the oil discharge pipe 4 and lower than the height of the gravity stratification baffle 31, the oil flowing into the first separation chamber 6 can pass through the through groove 32 and into the second separation chamber 7 and flow out from the oil discharge pipe 4.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
