Description

Technical Field

[0001] The utility model relates to the technical field of sampling detection, in particular to an automatic sampling system for a tanker truck. Background Art

[0002] Kitchen waste oil is the oil separated from the swill retained and discharged by hotels, restaurants and food processing enterprises, and can be used as raw materials to produce biodiesel, soap, etc. However, due to the complex sources of kitchen waste oil, the composition of kitchen waste oil is not stable. There are differences in different batches of kitchen waste oil.

[0003] Therefore, before using kitchen waste oil, it is necessary to sample and test to determine its composition, so as to adjust the subsequent production process accordingly to achieve the best production effect.

[0004] However, during the transportation of kitchen waste oil, due to the sedimentation effect of gravity, the composition of kitchen waste oil in different areas of a tanker truck is also different. The existing sampling method through the manhole on the top of the tank body cannot accurately reflect the overall situation of the kitchen waste oil in the tank body. As a result, the subsequent production process does not match perfectly with the kitchen waste oil, reducing the raw material conversion rate and the yield rate of good products. Summary of the Utility Model

[0005] In view of this, it is necessary to provide an automatic sampling system for a tanker truck to solve the technical problem that in the prior art, due to the uneven distribution of kitchen waste oil in the tanker truck, the existing sampling method is inaccurate.

[0006] The utility model provides an automatic sampling system for a tanker truck, which includes: a tank body, a circulation pipeline, a circulation pump, a sampling pipe and a control unit. Both ends of the circulation pipeline are connected to the tank body.

One end of the sampling pipe is connected to the circulation pipeline, and the other end is used to discharge the sample. The control unit is arranged on the sampling pipe to control the connection or closing of the sampling pipe.

[0007] Further, it further includes an eddy current distributor, which is connected to the liquid outlet end of the circulation pipeline and is arranged in the tank body.

[0008] Further, the eddy current distributor is arranged vertically to discharge the liquid at different heights.

[0009] Further, it further includes a static mixer, which is arranged on the circulation pipeline and is located between the circulation pump and the sampling pipe.

[0010] Further, it further includes a heater, which is arranged around the sampling pipe.

[0011] Further, it further includes a buffer tank which is arranged on the sampling pipe and is located behind the control unit along the liquid flow direction.

[0012] Further, it further includes a discharging valve which is arranged on the sampling pipe and is located behind the buffer tank along the liquid flow direction.

[0013] Further, the control unit includes a sampling valve arranged on the sampling pipe.

[0014] Further, the sampling valve adopts a pneumatic angle seat valve which is communicated with a gas source through a gas supply pipe, and a solenoid valve is arranged on the gas supply pipe to control the opening and closing of the gas supply pipe.

[0015] Further, the bottom of the tank body is provided with a subsea valve, and its top is provided with a manhole. One end of the circulation pipeline is communicated with the subsea valve, and the other end is inserted into the tank body through the manhole.

[0016] Compared with the prior art, the tanker automatic sampling system provided by the utility model drives the liquid in the tank body to circulate through the circulation pipeline and the circulation pump, so that the liquid in the tank body is evenly mixed, and then samples are taken through the sampling pipe, eliminating the problem of uneven distribution of the liquid in the original tank body, enabling the obtained samples to represent the overall level of the liquid in the tank body, and being beneficial to subsequent production.

[0020] The following will specifically describe the preferred embodiments of the utility model in conjunction with the accompanying drawings. The accompanying drawings constitute a part of this application and are used together with the embodiments of the utility model to explain the principle of the utility model, and are not used to limit the scope of the utility model.

[0021] Please refer to Figure 1, the present utility model provides an automatic sampling system for tank trucks. This automatic sampling system for tank trucks can be applied to the recycling of kitchen waste oil and grease, for sampling and testing before the recycling and reuse of kitchen waste oil and grease, so that the extracted sample can more accurately reflect the overall situation of the kitchen waste oil and grease in the tank body.

[0022] It should be noted that the automatic sampling system for tank trucks of the present utility model is used in but not limited to the sampling of kitchen waste oil and grease, and can also be applied to the sampling of other non-uniform liquids. In the present utility model, only the case where the automatic sampling system for tank trucks is applied to the sampling of kitchen waste oil and grease is taken as an example for illustration, and the principle of the automatic sampling system for tank trucks applied to the sampling of other liquids is substantially the same as that applied to the sampling of kitchen waste oil and grease, and will not be elaborated one by one here.

[0023] This automatic sampling system for tank trucks includes a tank body 1, a circulation pipeline 2, a circulation pump 3, a sampling pipe 4, and a control unit 5. Both ends of the circulation pipeline 2 are connected to the tank body 1, and the circulation pump 3 is arranged on the circulation pipeline 2 to drive the liquid in the tank body 1, which is kitchen waste oil and grease in this embodiment, to circulate along the circulation pipeline 2. One end of the sampling pipe 4 is connected to the circulation pipeline 2, and the other end is used to flow out the sample. The control unit 5 is arranged on the sampling pipe 4 to control the connection or closing of the sampling pipe 4.

[0024] By driving the kitchen waste oil and grease in the tank body 1 to circulate through the circulation pipeline 2 and the circulation pump 3, the kitchen waste oil and grease in the tank body 1 are mixed evenly, and then sampled through the sampling pipe 4, eliminating the problem of uneven distribution of the kitchen waste oil and grease in the original tank body 1. The obtained sample can represent the overall level of the kitchen waste oil and grease in the tank body 1, which is beneficial to subsequent production.

[0025] In some embodiments, the bottom of the tank body 1 has a subsea valve, and the top has a manhole. One end of the circulation pipeline 2 is connected to the subsea valve, and the other end is inserted into the tank body 1 through the manhole.

[0026] In some embodiments, it further includes a vortex distributor 6. The vortex distributor 6 is connected to the liquid outlet end of the circulation pipeline 2, and the vortex distributor 6 is arranged in the tank body 1. The vortex distributor 6 can disperse the kitchen waste oil and grease flowing out from the circulation pipeline 2 and accelerate the uniform mixing of the kitchen waste oil and grease in the tank body 1.

[0027] In the preferred embodiment, the vortex distributor 6 is arranged in the vertical direction to discharge the kitchen waste oil and grease to different heights. Discharging the kitchen waste oil and grease to different heights enables the kitchen waste oil and grease to be mixed evenly faster.

[0028] In some embodiments, it further includes a static mixer 7. The static mixer 7 is arranged on the circulation pipeline 2 and is located between the circulation pump 3 and the sampling pipe 4. The static mixer 7 can further mix and stabilize the kitchen waste oil and grease in the circulation pipeline 2, which is beneficial to sampling by the sampling pipe 4.

[0029] In some embodiments, a heater is further included. The heater is arranged around the sampling pipe 4 for heating the sampling pipe 4 to prevent the kitchen waste oil and fat in the sampling pipe 4 from solidifying and improve the fluidity of the kitchen waste oil and fat. The heater can adopt an electric heating wire and be wound around the sampling pipe 4.

[0030] In some embodiments, a buffer tank 8 is further included. The buffer tank 8 is arranged on the sampling pipe 4 and is located behind the control unit 5 along the liquid flow direction. The kitchen waste oil and fat sample flowing out of the circulation pipeline 2 first enters the buffer tank 8 for buffering.

[0031] In some embodiments, a discharging valve 9 is further included. The discharging valve 9 is arranged on the sampling pipe 4 and is located behind the buffer tank 8 along the liquid flow direction. After the kitchen waste oil and fat is buffered by the buffer tank 8, the discharging valve 9 is opened and the kitchen waste oil and fat flows out of the sampling pipe 4 for test detection.

[0032] In some embodiments, the control unit 5 includes a sampling valve 51 arranged on the sampling pipe 4. The sampling valve 51 can control the opening and closing of the sampling pipe 4.

[0033] In a preferred embodiment, to solve the problem that the solenoid valve is blocked by oil residue and cannot be completely closed, resulting in material leakage, the sampling valve 51 preferably adopts a pneumatic angle seat valve. The pneumatic angle seat valve is communicated with a gas source 53 through a gas supply pipe 52. A solenoid valve 54 is arranged on the gas supply pipe 52. A power supply 55 supplies power to the solenoid valve 54 and controls whether the solenoid valve works, so as to control the opening and closing of the gas supply pipe 52 and indirectly control the opening or closing of the sampling valve 51.

[0034] Compared with the prior art, the tanker automatic sampling system provided by the present utility model drives the liquid in the tank to circulate through the circulation pipeline and the circulation pump, so that the liquid in the tank is evenly mixed, and then samples are taken through the sampling pipe, eliminating the problem of uneven distribution of the liquid in the original tank, enabling the obtained samples to represent the overall level of the liquid in the tank, and being beneficial to subsequent production.

[0035] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model.
