Description

Technical Field

[0001] The utility model belongs to the technical field of collection devices, and in particular relates to a self-closing air inlet valve and a carbon black collection system. Background Art

[0002] The production process of carbon black is to generate powdered carbon black and flue gas through cracking reaction in the reactor, and terminate the reaction by rapid cooling. The flue gas containing carbon black dust is recovered through waste heat and then goes through a series of processes such as bag filtration, wet granulation, drying and packaging to finally obtain the finished carbon black.

[0003] In the prior art, a fan is usually used to drive the carbon black into a pipeline through airflow for transportation and collection. However, when the air blower fails and stops, the air mixed with powdered carbon black will flow back through the pipeline due to air pressure, resulting in a large amount of carbon black dust being dispersed in the air, causing a large amount of air pollution.

[0047] Please refer to all the drawings. In an illustrative embodiment of the self-closing air inlet valve of the present invention, the self-closing air inlet valve comprises: a connecting pipe 100 having an output end.

[0048] In some embodiments, the output end is used to connect to a carbon black collection system;

[0049] In some embodiments, the self-closing air inlet valve further includes a partition 200 , which is disposed in the connecting pipe 100 , and the partition 200 closes the connecting pipe 100 .

[0050] In some embodiments, a vent 300 is formed through the partition 200 .

[0051] In some embodiments, the self-closing air inlet valve further includes a baffle 500 , and the baffle 500 is disposed on a side of the partition 200 facing the output end.

[0052] In some embodiments, the top of the baffle 500 is hinged in the connecting pipe 100. The baffle 500 closes the vent 300 in a natural state.

[0053] When the airflow drives the carbon black into the connecting pipe 100 , the airflow pushes the baffle 500 to open the vent 300 ; when the airflow stops, the baffle 500 falls down and closes the vent 300 under the action of gravity.

[0054] Through the above solution, the design of the connecting pipe 100, the partition plate 200, and the baffle plate 500 realizes the function of automatically opening the vent 300 under the action of the airflow, and automatically closing the vent 300 when the airflow stops. This design can effectively prevent the reverse flow of carbon black in the system, improve the safety and stability of the system, and avoid pollution.

[0055] In some embodiments, the connecting tube 100 may be a round tube, and the cross section of the connecting tube 100 is circular.

[0056] In some embodiments, the connecting tube 100 may be a square tube, and the cross section of the connecting tube 100 is rectangular.

[0057] In some embodiments, the side of the connecting pipe 100 away from the baffle 500 is the input end. Air enters the connecting pipe 100 through the input end and enters the carbon black collection system from the output end through the vent 300.

[0059] In some embodiments, the partition 200 is tilted, and the partition 200 tilts from top to bottom toward the side close to the output end. In a natural state, the baffle 500 is attached to the side of the partition 200 facing the output end.

[0060] It is worth noting that the material of the baffle 500 can be selected from a material with a lower density to reduce the mass of the baffle 500 , so as to facilitate the air to push the baffle 500 .

[0061] In some embodiments, the partition 200 and the interior of the connecting pipe 100 may be fixedly connected.

[0062] The connection method can be an integrated molding setting, thereby improving the structural strength.

[0068] In some embodiments, the side of the vent 300 facing the output end is connected to the vent pipe 400, and the end surface of the vent pipe 400 facing the output end is inclined from top to bottom toward the output end; the baffle 500 is arranged on the side of the vent pipe 400 facing the output end. The side of the vent 300 facing the output end is connected to the vent pipe 400, and the end surface of the vent pipe 400 is also designed to be inclined. This design makes it easier for the baffle 500 to open the vent 300 under the action of airflow, while ensuring the sealing of the baffle 500 when closing the vent 300.

[0069] In some embodiments, the length direction of the connecting pipe 100 is perpendicular to the partition 200. The vent 300 penetrates the partition 200 along the length direction of the connecting pipe 100 to ensure that the vent 300 has the largest windward surface and improve the amount of airflow.

[0070] In some embodiments, the length direction of the ventilation pipe 400 is the same as the length direction of the connecting pipe 100 .

[0071] In another embodiment, the length direction of the ventilation pipe 400 is perpendicular to the partition plate 200 .

[0081] In some embodiments, a filter screen 700 is disposed at one end of the connecting pipe 100 away from the output end. The filter screen 700 is disposed at one end of the connecting pipe 100 away from the output end, which can effectively filter impurities in the airflow entering the connecting pipe 100, prevent impurities from entering the carbon black collection system, and ensure the purity and working efficiency of the system.

[0082] In some embodiments, the shape of the filter screen 700 is the same as the shape of the opening of the input end of the connecting pipe 100. The filter screen 700 can completely cover the input end of the connecting pipe 100 to ensure its filtering effect.

[0084] In some embodiments, the filter screen 700 is inclined from top to bottom in a direction away from the output end of the connecting pipe 100 .

[0085] In some embodiments, when the baffle 500 closes the vent 300 , the filter 700 is parallel to the baffle 500 .

[0086] In some embodiments, the pressing member 800 is in a frame shape, and its shape is the same as the edge shape of the input end of the connecting pipe 100. The pressing member 800 presses the filter screen 700 tightly against the input end of the connecting pipe 100.

[0087] In some embodiments, a threaded member is passed through the pressing member 800, and the threaded member fixes the pressing member 800 to the connecting pipe 100. In this way, the filter screen 700 is fixed, and when the filter screen 700 needs to be replaced, the threaded member can be removed for replacement.

[0088] In some embodiments, the threaded member passes through the pressing member 800 and the filter screen 700 and is threadedly connected to the input end of the connecting pipe 100 .

[0090] In some embodiments, the threaded member sequentially passes through the pressing member 800, the filter screen 700 and the first flange and is then threadedly connected with a nut. The pressing member 800, the filter screen 700 and the first flange are compressed by the nut and the threaded member to fix the filter screen 700. This method can also adjust the tightness of the filter screen 700 by adjusting the position of the nut.

[0091] In some embodiments, the threaded member includes, but is not limited to, a bolt or a screw.

[0092] In some embodiments, a plurality of screw members are spaced apart along the edge of the pressing member 800 to improve the connection stability.
