Description

Technical Field

[0001] This utility model relates to the technical field of sampling devices for coking production, and in particular to a continuous sampling device for coal coking. Background Technology

[0002] Coking, also known as high-temperature coal carbonization, refers to a coal conversion process that uses coal as raw material, heats it to about 950°C in the absence of air, and produces coke through high-temperature carbonization. Simultaneously, it yields coal gas and coal tar, and recovers other chemical products. The main use of coke produced by coal coking is in iron smelting, with a small amount used as a chemical raw material in the manufacture of calcium carbide, electrodes, etc.

[0003] In the coal coking production process, to ensure safety and environmental protection, it is necessary to periodically sample and test the gases generated during production at specific locations. However, existing sampling devices are often independent components, requiring the device to be placed at the sampling port for operation, and then removed for sample extraction and testing. This process is not only cumbersome but also prevents continuous sampling, thus affecting sampling and testing efficiency. Therefore, this application proposes a continuous sampling device for coal coking to solve the aforementioned problems. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a continuous sampling device for coal coking. The technical solution to the problem it solves is as follows: it includes a sampling cylinder, characterized in that a flange is connected to a docking plate at the upper end of the sampling cylinder, a pull-out device electrically connected to a controller is arranged at the upper end of the docking plate, a sampling component is integrally and coaxially arranged at the lower end of the sampling cylinder, a discharge component is fixedly connected to one side of the bottom of the sampling cylinder, a stopper rod is coaxially and slidably connected to the sampling cylinder, and a piston that slides against the inner wall of the sampling cylinder is coaxially and fixedly connected at the lower end of the stopper rod.

[0005] The pull-out device includes two support rods fixedly connected to the docking plate. The upper ends of the two support rods are fixedly connected to I-shaped connecting seats. The connecting seats are rotatably connected to the opposite ends of the docking plate by a lead screw. The connecting rods are also fixedly connected to the opposite ends of the docking plate by a vertical shaft. The right end of the lead screw is threadedly connected to the vertical moving rod. The left end of the vertical moving rod is slidably connected to the vertical shaft. The middle part of the stopper rod is fixedly connected to the stopper rod. A motor for driving the lead screw is fixedly connected to the connecting seat.

[0006] Preferably, the left end of the vertical moving rod is integrally provided with a guide sleeve that is slidably connected to the vertical rod, and the right end of the vertical moving rod is integrally provided with a threaded sleeve that is threadedly connected to the lead screw.

[0007] Preferably, the sampling assembly includes a sampling head arranged coaxially with the sampling cylinder, and a first one-way valve is fixedly installed inside the sampling head. The first one-way valve only allows external gas to flow unidirectionally into the sampling cylinder.

[0008] Preferably, the sampling assembly includes a sampling head that is fixedly connected to one side of the bottom of the sampling cylinder. A second one-way valve is fixedly installed inside the sampling head. The second one-way valve only allows the gas in the sampling cylinder to flow unidirectionally to the outside. The outlet end of the sampling head is fixedly connected to the inlet end of a long conduit.

[0009] Preferably, the upper end of the sampling cylinder is integrally provided with a docking flange for connection to the docking plate flange.

[0010] The beneficial effects of this utility model are:

[0011] This application allows the device to be fixed to locations requiring frequent sampling via bolts through the connecting holes on the connector. When sampling is needed, simply control the motor to rotate forward for the set stroke. This causes the lead screw to rotate forward by the corresponding stroke, which in turn drives the vertical moving rod to move upward along the vertical axis by the same stroke. The vertical moving rod then moves the stopper rod upward along the sampling cylinder in the same manner. The upward movement of the stopper rod draws in external gas through the piston, allowing the gas to pass through the sampling head and the first one-way valve into the sampling cylinder. Then, the motor is restarted in reverse to complete the same stroke. This reverse rotation causes the lead screw to reverse its stroke and drive the stopper rod downward to reset, discharging the extracted gas through the long conduit of the discharge assembly. The operator only needs to collect the sample at the outlet end of the long conduit. This application features a simple structure, ease of use, and strong practicality. Furthermore, it allows for continuous sampling by controlling the motor of the extraction device, significantly improving sampling and testing efficiency. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0019] In the first embodiment, the technical solution is that the present application can be fixed to the part that needs frequent sampling by means of bolts through the connecting hole 21 on the connecting seat 9. When sampling is required, the motor 13 is controlled to rotate forward by a set stroke, and the lead screw 10 will rotate forward by the corresponding stroke. The forward rotation of the lead screw 10 will drive the vertical moving rod 12 to move upward along the vertical axis 11 by the corresponding stroke. The vertical moving rod 12 will drive the stopper rod 6 to move upward along the sampling cylinder 1 in the same way. The upward movement of the stopper rod 6 will draw in the external gas through the piston 7, so that the external gas enters the sampling cylinder 1 through the sampling head 16 and the first one-way valve 17. Then, the motor 13 is started to reverse the stroke in the same way. The reverse rotation of the motor 13 will cause the lead screw 10 to reverse the corresponding stroke and drive the stopper rod 6 to return downward. The extracted gas will then be discharged through the long conduit 20 of the discharge assembly 5. The operator only needs to collect the sample at the outlet end of the long conduit 20. This application has a simple structure, is easy to use, and is highly practical. It can also continuously sample by controlling the motor 13 of the pull-out device 3, which greatly improves the efficiency of sampling and detection.

[0020] In Example 2, based on Example 1, specifically, during use, this application is fixed at the sampling point using bolts through the connecting hole 21 on the connecting seat 9. During sampling, the motor 13 of the pull-out device 3 is started to rotate forward to the set stroke. The motor 13 then drives the lead screw 10, which is rotatably connected between the docking plate 2 and the connecting seat 9, to rotate forward to the corresponding stroke. The forward rotation of the lead screw 10 drives the vertical moving rod 12 through the threaded sleeve 15. The vertical moving rod 12 is restricted by the sliding connection between the guide sleeve 14 and the vertical shaft 11. Therefore, the forward rotation of the lead screw 10 drives the vertical moving rod 12 to move upward. The vertical moving rod 12 then drives the stopper rod 6 to move upward a corresponding distance. The upward movement of the stopper rod 6 drives the piston 7 to move upward synchronously. Under the action of the piston 7, the gas at the sampling point enters the sampling cylinder 1 through the sampling head 16 and the first one-way valve 17 of the sampling assembly 4, thereby completing the gas sampling operation.

[0021] After sampling is completed, the motor 13 is restarted in reverse to form the same result. The reverse rotation of the motor 13 will cause the lead screw 10 to rotate synchronously in reverse. In turn, the lead screw 10 will drive the vertical moving rod 12 and the stopper rod 6 to move downwards by the corresponding stroke. As a result, the piston 7, which is fixedly connected to the stopper rod 6, will also move downwards to reset. During the downward movement and reset of the piston 7, the sample gas in the sampling cylinder 1 will be compressed through the second one-way valve 19 and the sample discharge head 18, so that the sample gas in the sampling cylinder 1 can enter the long conduit 20. The operator can collect the sample at the other end of the long conduit 20.

[0022] In Embodiment 3, based on Embodiment 2, the I-shaped connecting seat 9 facilitates the connection between this application and the equipment at the sampling point, thereby completing the fastening of this application. The two support rods 8 provide stable support and connection for the pull-out device 3 of this application.
