Description

Technical Field

[0001] The utility model relates to the technical field of carbon black production equipment, in particular to a carbon black sampling device with better air tightness and greater safety. Background Art

[0002] With the rapid development of industrial technology, carbon black, as an important industrial raw material, has been widely used in many fields such as rubber, plastics, inks, and coatings. In the production and use of carbon black, accurate measurement and sampling analysis of its content is particularly important. However, traditional carbon black sampling equipment has many deficiencies in air tightness and safety, which affects the accuracy of sampling results and the safety of operators.

[0003] During the sampling process, the traditional carbon black sampling equipment often causes the carbon black samples to be contaminated by the external environment due to unreasonable equipment structure or poor sealing performance, thus affecting the accuracy of the measurement results. In addition, the dust and harmful gases that may be generated during the sampling process pose a potential threat to the health of the operators and reduce the safety of the sampling process.

[0004] Therefore, developing a carbon black sampling device with good air tightness and safety is of great significance for improving the accuracy of carbon black content measurement and ensuring the safety of operators. This patent aims to provide a new type of carbon black sampling device, which can achieve efficient and accurate carbon black sampling by optimizing the device structure and sealing performance, while ensuring the safety and reliability of the operation process.

[0005] Specifically, the patented carbon black sampling equipment uses advanced sealing technology to ensure the isolation of the equipment from the external environment during the sampling process, effectively preventing the carbon black sample from being contaminated. At the same time, the equipment is equipped with an efficient dust collection device and a harmful gas treatment system, which can collect and treat the dust and harmful gases generated during the sampling process in real time to ensure the health and safety of the operator.

[0006] For example, a Chinese patent (application number: 202222025106.X) discloses an automatic sampling device for carbon black, including a conveying motor, wherein the output end of the conveying motor is connected to a reducer, and a rotating shaft is provided at the output end of the reducer, a sampling tube is sleeved on the rotating shaft, a feeding port is provided on the sampling tube away from the reducer, a discharge pipe connected to the inside of the sampling tube is provided at the bottom of the sampling tube close to the reducer, a sample storage container is provided at the bottom of the discharge pipe, and a spiral blade is provided on the rotating shaft between the discharge pipe and the feed port. The utility model can achieve online continuous and uniform sampling, provide more real and accurate samples for carbon black quality testing, reduce the number of carbon black production operation adjustments, and make the production process more stable. The utility model adopts sealed sampling and will not cause pollution to the surrounding environment.

[0007] However, during the sampling process of this type of equipment, outside air will still enter the cracking equipment from the discharge gap, posing a potential safety hazard to production. Utility Model Content

[0008] In order to solve the above problems, the embodiment of the utility model provides a carbon black sampling device with good air tightness, simple structure and easy operation.

[0009] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a carbon black sampling device, comprising a hopper connected to a production device, a sampling module is arranged on the outside of the hopper, and a conveying device is arranged between the sampling module and the hopper;

[0010] The sampling module comprises a silo, a feed pipe connected to a conveying device is arranged on the top of the silo, a first valve is arranged on the feed pipe, a sampling port is arranged at the bottom of the silo, and a second valve is arranged at the sampling port.

[0011] As a further improvement of the above technical solution:

[0012] The conveying device comprises a conveying pipeline, in which a spiral blade is arranged, one end of the conveying pipeline extends into the hopper, and the other end of the conveying pipeline is provided with a driving source for driving the spiral blade to rotate.

[0013] A discharge port connected to a feed pipe is arranged in the middle of the conveying pipeline, and a feed port is arranged on the upper surface of one end of the conveying pipeline located in the hopper.

[0014] A material guide plate is arranged in the material bin, and a cleaning port is arranged on the side wall of the material bin.

[0015] The material guide plate is installed obliquely at the bottom of the material bin, and the lower end of the material guide plate faces the sampling port.

[0016] The beneficial effects of the embodiments of the utility model are as follows: 1. A carbon black sampling device comprises a hopper connected to a production equipment, a sampling module is arranged on the outside of the hopper, a conveying device is arranged between the sampling module and the hopper, the sampling module comprises a silo, a feeding pipe connected to the conveying device is arranged on the top of the silo, a first valve is arranged on the feeding pipe, a sampling port is arranged at the bottom of the silo, a second valve is arranged at the sampling port, and the silo is sealed during feeding and discharging by the two valves to ensure that outside air does not enter the silo during the carbon black taking process, thereby ensuring the air tightness and safety of the entire equipment during sampling.

[0017] 2. The design of the guide plate can ensure that the material is accumulated in the silo toward the sampling port, and when sampling, it can prevent outside air from entering the entire cracking equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] like Figure 1-3 As shown, the carbon black sampling device of this embodiment includes a hopper 1 connected to the production equipment, a sampling module is installed on the outside of the hopper 1, and a conveying device is provided between the sampling module and the hopper 1, and the material can be conveyed into the sampling module through the conveying device;

[0024] The sampling module includes a silo 2. A feed pipe 3 connected to a conveying device is provided on the top of the silo 2. A first valve 4 is provided on the feed pipe 3. A sampling port 5 is provided at the lower part of the silo 2. A second valve 6 is provided at the sampling port 5. During the sampling process, the first valve 4 is used to cut off the connection between the silo and the conveying device, and then the second valve 6 is opened to perform sampling operations. The first valve 4 and the second valve 6 are double-blocked during sampling, which can ensure the airtightness and safety during the sampling operation.

[0025] The conveying device includes a conveying pipe 7, in which a spiral blade 8 is provided. One end of the conveying pipe 7 extends into the hopper 1, and the other end is provided with a driving source 9 for driving the spiral blade 8 to rotate. The carbon black is conveyed through the conveying pipe 7, which can ensure the air tightness during the conveying process and prevent the material from contacting with the outside air during transportation.

[0026] A discharge port 10 connected to the feed pipe 3 is provided in the middle of the conveying pipe 7, and a feed port 11 is provided on the upper surface of one end of the conveying pipe 7 located in the hopper 1. The feed port 11 is located in the hopper, and the discharge port 10 is connected to the feed pipe 3. Both places are in a sealed state to ensure air tightness during the conveying process.

[0027] A material guide plate 12 is provided in the silo 2, and a cleaning port 13 is provided on the side wall of the silo 2. The cleaning port 13 is designed separately from the sampling port 5, and the cleaning port 13 is covered with a sealing plate and is in a sealed state during normal operation.

[0028] The guide plate 12 is installed obliquely at the bottom of the silo 2, with the lower end of the guide plate 12 facing the sampling port 5. After the carbon black is transported into the silo 2, it will accumulate at the sampling port 5 under the action of the guide plate 12. The advantage of this design is that when sampling is required, the second valve 6 is opened, and the material will fall first because it is accumulated at the sampling port 5. After the sampling is completed, the second valve 6 can be closed, and the outside air will not enter the silo during the whole process.
