Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil fume exhaust pipes, in particular to an oil collecting device for the oil fume exhaust pipe. Background Art
[0002] Usually, the kitchen range fumes exhaust system directly connects the horizontal range fumes exhaust duct to the vertical air duct, or lines the horizontal range fumes exhaust duct and the vertical air duct with stainless steel air duct. However, at the beginning of the range fumes exhaust system, the oil in the flue gas is still in gaseous state. When it hits the air duct at the rear end, it will become liquid when it is cooled. As the temperature drops and time passes, these liquid oils will adhere to the wall of the air duct, and more and more, so as to affect the normal air speed of the air duct and the range fumes exhaust effect. Over time, it will also corrode the air duct, causing pollution such as oil leakage, and there are also safety hazards.
[0003] Prior art CN 215832014 U discloses an oil collection device for kitchen exhaust ducts. The device comprises an oil fume delivery pipe, a vertical exhaust duct with a closed lower end and a collection assembly installed therein. The collection assembly comprises an oil collection hopper connected to the lower end of the vertical exhaust duct, and an oil removal bucket threadedly connected to the lower end of the oil collection hopper. A flow guide assembly is installed within the vertical exhaust duct. Although the oil collection device can collect some oil within the exhaust duct, the flow guide plate of the flow guide assembly is located at the corner between the vertical exhaust duct and the horizontal exhaust duct. This not only affects the air velocity within the exhaust duct but also reduces the oil collection effect. The diverted oil fume will adhere to the duct wall at the corner, thus preventing effective oil collection. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an oil collecting device for an oil fume exhaust pipe.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Furthermore, the air guide plate includes a main air guide plate and an auxiliary air guide plate. The main air guide plate is arranged on the inner wall of the vertical air duct connected to the opposite side of the horizontal air duct, and the auxiliary air guide plate is arranged on the inner wall of the vertical air duct connected to the side of the horizontal air duct. The lower end of the main air guide plate is an arc-shaped plate, the upper end of the main air guide plate is a wavy plate, and the auxiliary air guide plate is a wavy plate; the air guide plate is arranged to be wavy to retain oil smoke to a greater extent.
[0008] Furthermore, the lower end of the main air guide plate is flush with the lower ends of the horizontal air duct and the vertical air duct, which will not affect the wind speed of the smoke exhaust and has a guiding effect.
[0009] Furthermore, the oil collecting device includes an oil collecting hopper and an oil collecting tank. The oil collecting tank is provided at the bottom of the oil collecting hopper, and an oil drain pipe is provided at the bottom of the oil collecting tank. A ball valve is provided on the oil drain pipe. There is no need to disassemble the oil for draining. It is more convenient to drain the oil through the ball valve and the oil drain pipe.
[0010] Furthermore, an oil level gauge is provided on the oil collecting tank, which facilitates observation of the oil level in the oil collecting tank and timely cleaning.
[0011] Furthermore, the inner walls of the oil collecting hopper and the oil collecting tank are provided with an amphiphobic coating to prevent oil from adhering to the inner walls and reduce cleaning and maintenance.
[0012] Furthermore, a biphobic coating is provided on the surface of the air guide plate, so that the oil smoke blocked on the air guide plate can flow into the oil collecting hopper and the oil collecting tank better.
[0013] Furthermore, the amphiphobic coating is a Teflon amphiphobic coating or a silicon dioxide nano-amphiphobic coating or a nano-ceramic coating.
[0014] The beneficial effects of the present invention are as follows: the device can effectively discharge the smoke oil on the pipe wall at the starting end of the oil fume exhaust duct, effectively ensure the normal operation of the oil fume exhaust system, reduce the corrosion of the air duct caused by the smoke oil pushing, and at the same time has the advantages of easy operation, simple production and strong versatility.
