Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the automatic sampling device disclosed in the present application, the sampling device is composed of a sampling pipeline 11, an electric telescopic rod 12, a sampling bin 13, a sampling port 14, a sealing ring 15, a spring 16, a limiting member 17, and the like, specifically, the sampling pipeline 11 is installed on a feeding pipeline, and two ends of the feeding pipeline are connected with different production equipment for transferring raw materials between processes.

The electric telescopic rod 12 is installed on the sampling pipeline 11, and the piston of the electric telescopic rod 12 extends into the sampling pipeline 11. The sampling chamber 13 is fixed on the piston of the electric telescopic rod 12 and can do linear reciprocating motion along the axis of the sampling pipeline 11.

In some possible implementations, the electric telescopic rod 12 uses an electric cylinder.

The sampling bin 13 is provided with a sampling port 14, the sampling bin 13 is further sleeved with a sealing ring 15, and the sealing ring 15 is used for sealing the sampling port 14 on the sampling bin 13. The movement of the sealing ring 15 is effected by a spring 16 and a stop 17.

The two ends of the spring 16 are respectively connected with the sampling bin 13 and the sealing ring 15, and are used for pulling the sealing ring 15 to close the sampling port 14, and the limiting piece 17 is fixed on the inner wall of the sampling pipeline 11 and is used for enabling the sealing ring 15 to stay in the sampling pipeline 11.

When the sampling device is used for sampling, the electric telescopic rod 12 acts to push the sampling bin 13 to move out of the sampling pipeline 11, the sampling bin is intercepted by the limiting piece 17, the sealing ring 15 stays in the sampling pipeline 11, and the sampling bin 13 extends out of the sampling pipeline 11.

The sampling bin 13 extends out of the sampling pipeline 11 and then enters the feeding pipeline, the sampling port 14 on the sampling bin 13 is changed into an open state from a closed state, a part of raw materials in the feeding pipeline enters the sampling bin 13, then the sampling bin 13 retracts into the sampling pipeline 11, and the sampling port 14 on the sampling bin 13 is changed into a closed state from an open state.

In the sampling process, the electric telescopic rod 12 can move for multiple times, and a certain amount of sample can be collected in each movement, so that the sample can more accurately react the proportion among the components in the raw materials.

Referring to fig. 3, as an embodiment of the automatic sampling device, a sampling port 111 and a cover plate 112 are added to the sampling pipe 11, and the cover plate 112 is used to close the sampling port 111. Specifically, after the sampling is completed, the worker can open the cover plate 112, take out the sample in the sampling chamber 13 from the sampling port 111 or remove the sampling chamber 13 from the electric telescopic rod 12 and replace the sampling chamber 13 with a new one, that is, the sampling chamber 13 can be detachably connected to the piston of the electric telescopic rod 12, for example, by using a screw connection.

In some possible implementations, the cover plate 112 is hinged to the sampling pipe 11.

In other possible implementations, the cover plate 112 may be removably secured to the sampling pipe 11, for example using a bolted connection.

Referring to fig. 2, as an embodiment of the automatic sampling device provided by the application, the number of the sampling ports 14 is multiple and the sampling ports are uniformly distributed on the sampling bin 13, so that in a single sampling process, samples at multiple different positions can be obtained, and the sampling result can be more accurate.

Referring to fig. 1 and 2, as a specific embodiment of the automatic sampling device provided by the application, a purge pipeline 21 is further added, a first end of the purge pipeline 21 extends into the sampling pipeline 11 and faces one end of the sampling pipeline 11, which is used for being connected with the feeding pipeline, and the purge pipeline 21 is used for injecting compressed gas into the sampling pipeline 11, so that the gas pressure in the sampling pipeline 11 is increased, and raw materials in the feeding pipeline are prevented from entering the sampling pipeline 11.

Referring to fig. 1 and 4, the air intake of the purge line 21 is realized by a valve, and when the switch is closed, the valve is powered on and is changed from a closed state to an open state, and when the switch is powered off, the valve is closed.

The control of the electric telescopic rod 12 is realized by a timer and a commutator, the timer works after being electrified, the commutator signals are given according to the frequency, and the commutator changes the current direction once inputting to the electric telescopic rod 12 when receiving one signal, thereby realizing the extension and retraction of the piston of the electric telescopic rod 12.
