[0002] With the continuous acceleration of urbanization and the continuous improvement of people's living standards, the catering industry is developing day by day in cities, bringing many problems to be solved urgently. In particular, the oil fume purification of kitchen exhaust pipes is not thorough, there is no corresponding fire prevention measure, a large amount of oil scale accumulates in the pipes after long-term use and cannot be cleaned in time, and the open fire on the stove is easily inhaled into the interior of the oil fume pipe well. The accumulated oil scale in the pipe is extremely easy to cause a fire when encountering an open fire. At the same time, the unpurified oil fume is directly discharged outdoors, causing air pollution to the surrounding environment and affecting people's daily life, life and property safety. At the same time, due to the long-term inability to clean the accumulated oil scale inside the kitchen oil fume well, the pipe connecting to the oil separation tank is blocked. Manually cleaning the pipe is time-consuming, laborious, extremely unhygienic and ineffective. Even if there is a cleaning port, it is very difficult to clean the blockage in a short time, causing inconvenience to later use and maintenance. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the technical solutions of the present utility model will be further described in detail below with reference to the drawings in the embodiments of the present utility model.

[0017] Referring to Figures 1 to 4 , a kitchen oil fume well oil dilution and anti-blockage dredging device according to the present utility model includes a timing discharge box 4, a transmission pipe 3, an oil guiding rack 5, an oil collecting tank 8 and a bottom groove 10. The oil guiding rack 5, the oil collecting tank 8 and the bottom groove 10 are successively installed in the oil fume well 1 from top to bottom. The timing discharge box 4 is installed on the outer side wall of the oil fume well 1 and can discharge the diluent regularly and quantitatively. The transmission pipe 3 is connected to the outlet end of the timing discharge box 4 and is spirally arranged inside the top port of the oil collecting tank 8 in a circumferential manner. A plurality of spray nozzles 7 are provided on the pipe body of the transmission pipe 3 spiraling around the top port of the oil collecting tank 8.

[0018] A fire door 2 is provided on the side wall of the fume well 1, and the installation height of the oil collecting tank 8 is equivalent to the height of the fire door 2. The device is located in the middle and lower part of the fume well 1. The oil collecting tank 8 is close to the fire door 2 to facilitate daily cleaning and maintenance.

[0019] A support beam 9 is fixedly mounted within the fume silo 1 via expansion bolts 6. A funnel-shaped oil sump 8 is removably mounted on this support beam 9. A funnel-shaped oil guide frame 5 is secured within the fume silo 1 via expansion bolts 6. A bottom trough 10 is located at the very bottom of the fume silo 1 and is connected to a conduit 11 that connects to the grease trap.

[0020] The timed discharge box 4 consists of an intelligent controller panel, a storage container and a pump. It can discharge diluent in a timed and quantitative manner. It is easy to adjust, safe and controllable. It is installed on the outside of the fume well 1. During installation, a 30mm hole is reserved on the wall of the fume well 1. The transmission pipe 3 is connected to the outlet end of the timed discharge box 4 through the hole.

[0021] The cross-sectional dimensions of the oil guide frame 5 are similar to those of the oil fume well 1, with a larger upper end and a smaller lower end, forming a funnel shape; the sides of the oil guide frame 5 are fixed to the wall of the oil fume well 1 with fixed expansion bolts 6, and the gaps are sealed with oil-isolating sealant 12 to prevent oil and dirt from leaking along the gaps.

[0022] The utility model uses a supporting beam 9 to support the oil collecting tank 8, and fixes the supporting beam 9 to the side wall of the oil fume pit 1 through an expansion bolt 6. The oil collecting tank 8 can slide on the L-shaped stainless steel supporting beam 9, and its installation height matches the height of the door opening of the fire door 2. The fire door 2 can be opened to take out the oil collecting tank 8 for cleaning and maintenance.

[0023] A plurality of transmission pipes 3 are arranged in a spiral circle around the inner side of the oil collecting tank 8, and nozzles 7 are evenly and equidistantly arranged on the transmission pipes 3. Diluent can be sprayed out from the nozzles 7. After the oil stains are diluted and dissolved, the diluted mixture will flow into the bottom tank 10 along the side wall of the oil collecting tank 8.

[0024] The bottom tank 10 is located at the bottom of the oil smoke pit 1 and is fixed by expansion bolts 6. A stainless steel conduit 11 connected to the grease trap is provided at the bottom of the bottom tank 10 to facilitate the flow of the diluted oil and dirt mixture into the grease trap.

[0025] To sum up, the working principle of this device is as follows: when oil smoke is sucked into the oil smoke well 1, oil stains accumulate on the side walls and slide downward along the inner wall of the well. The oil stains first flow into the oil guide frame 5, which is funnel-shaped, and the oil stains flow into the oil collecting tank 8 along the side walls of the oil guide frame 5. At the same time, the diluent is pumped out from the inside of the dilution timing discharge box 4 and flows into the oil collecting tank 8 along the transmission pipe 3. After the oil stains are diluted and dissolved, the diluted mixture flows into the bottom tank 10 along the side walls of the oil collecting tank 8 and flows into the grease trap through the conduit 11.

[0026] Under the action of gravity, this device can collect and dilute the oil dirt remaining in the oil fume duct in the oil collection tank, and quickly discharge the diluted oil and dirt mixture to the oil interceptor, preventing pipeline blockage caused by the accumulation of oil dirt and avoiding fires caused by oil dirt encountering an open flame. Moreover, this device can perform stably under high load and impact load, is convenient for construction, labor-saving in installation, can improve construction efficiency, and has characteristics such as anti-slip and anti-corrosion. At the same time, the utility model combines a civil engineering kitchen oil fume duct, a Class A fireproof steel door for maintenance, and an integrated oil fume dilution, anti-blocking and dredging device prefabricated in the factory, with a simple and concise shape, beautiful and generous, can be effectively connected with the traditional oil interceptor, and the device is convenient and flexible to replace, can greatly reduce the cleaning difficulty and cleaning time, reduce the construction and later maintenance costs. At the same time, this device can meet the requirements of standardized design, production and construction, and has a high degree of industrialization. This device is more practical, flexible and economical than other similar kitchen oil fume duct oil fume dilution, anti-blocking and dredging devices.
