Description

Technical Field

[0001] The utility model relates to the technical field of waste gas grease processing, in particular to a sampling device for waste grease processing. Background Art

[0002] Waste grease refers to waste edible animal and plant fats and wastewater containing edible animal and plant fats generated in catering services, food production and processing, and food preparation and sales activities other than daily life. The usual treatment method is to pour the recycled sewage into the raw material pool through the recycling vehicle, and then enter the solid-liquid separator for crushing and heating solid-liquid separation after sedimentation in the raw material pool. The separated slurry enters the reactor and is heated to 80°C in the reactor for reaction. The grease generated by the reactor flows to the oil collection tank for temporary storage.

[0003] At present, when inspectors take samples of grease temporarily stored in the oil collecting tank, they usually use an external sampler to reach into the oil collecting tank for sampling, or directly take samples through the discharge valve. Although the above methods meet the sampling needs of inspectors, there are still many inconveniences. On the one hand, the oil collecting tank cannot be put into use during sampling, that is, the oil collecting tank must be isolated from the grease processing system to ensure the safety of sampling; on the other hand, it is inconvenient for staff to operate, sampling is difficult, time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to solve the above problem and provides a sampling device for waste oil processing.

[0005] The utility model is realized through the following technical scheme: a sampling device for waste oil processing, comprising an oil collecting tank, characterized in that a sampling tube is provided on one side of the bottom of the oil collecting tank, a sampling control valve is provided on the sampling tube, one end of the sampling tube is connected to the oil collecting tank, and the other end is connected to a three-way conversion joint, the lower end opening of the three-way conversion joint is connected to a lower liquid pipe, a drip nozzle is provided at the bottom of the lower liquid pipe, the right end opening is connected to a flushing pipe, a flushing valve is provided on the flushing pipe, and a quick-plug connector is provided at the end of the flushing pipe.

[0006] Furthermore, the quick-connect connector is connected to an external flushing system via a hose.

[0007] Furthermore, the diameter of the lower port of the drip nozzle is 1-2 cm.

[0008] The beneficial effects of the utility model are as follows: the utility model opens another pipeline at one side of the bottom of the oil collecting tank as a sampling tube, and sets a sampling control valve, so that the inspector can directly take samples without being affected by whether the oil collecting tank is in use, and the sampling is safe and convenient. The utility model also sets a quick-connect connector to connect to an external flushing system, and regularly flushes the sampling tube, effectively preventing the sampling tube from being blocked, and avoiding the influence of the sample on the sample caused by the attachment of the sampling tube wall due to long-term sampling.

[0009] The utility model has a simple structural design and strong practicability and can effectively improve the sampling efficiency and sampling safety of inspectors. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the utility model.

[0011] In the attached figure, 1 is an oil collecting tank, 2 is a sampling tube, 3 is a sampling control valve, 4 is a three-way conversion joint, 5 is a liquid down pipe, 6 is a drip nozzle, 7 is a flushing tube, 8 is a flushing valve, and 9 is a quick-connect joint. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with embodiments.

[0013] like Figure 1 As shown, a sampling device for waste oil processing includes an oil collecting tank 1, a sampling tube 2 is provided on one side of the bottom of the oil collecting tank 1, a sampling control valve 3 is provided on the sampling tube 2, one end of the sampling tube 2 is connected to the oil collecting tank 1, and the other end is connected to a three-way conversion joint 4, the lower end opening of the three-way conversion joint 4 is connected to a lower liquid pipe 5, a drip nozzle 6 is provided at the bottom of the lower liquid pipe 5, and the lower end diameter of the drip nozzle 6 is 1-2cm. The right end opening of the three-way conversion joint 4 is connected to a flushing pipe 7, a flushing valve 8 is provided on the flushing pipe 7, and a quick connector 9 is provided at the end of the flushing pipe 7. The quick connector 9 is connected to an external flushing system through a hose, and a flushing pump is provided in the external flushing system. The flushing pump is used to pressurize the medium into the sampling device to achieve flushing.

[0014] When it is necessary to sample and test the processed grease in the oil collecting tank 1, the staff will place the sampling bottle under the drip nozzle 6 and open the sampling control valve 3. At this time, the grease in the oil collecting tank 1 will pass through the sampling tube 2, the three-way conversion joint 4, the down-liquid pipe 5 to the drip nozzle 6, and drip into the sampling bottle from the drip nozzle 6. After the sampling scale in the sampling bottle is met, the sampling control valve 3 is closed to complete the sampling. Then, the sampling bottle is covered with a lid and taken back to the laboratory for testing and analysis to obtain relevant data.

[0015] Since grease is viscous and will adhere to the sampling tube 2, the sampling device needs to be flushed regularly. The flushing medium uses a solution that can dissolve grease. The medium enters the hose through the flushing pump, enters the three-way conversion joint 4 through the hose, and enters the sampling tube 2 and the downpipe 5 for flushing. The flushing solution is discharged through the drip nozzle 6.

[0016] Except for the technical features described in the specification, the other technical features are known to those skilled in the art.
