Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a nitrogen bubbling device for a kettle bottom valve with uniform stirring. Background Art

[0002] Reactor is a comprehensive reaction vessel, generally used as a reaction vessel for the process of sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, condensation and other processes of various chemical raw materials. Reactor is usually equipped with mechanical stirring to make the reaction materials stir evenly, but some special reaction types are not suitable for mechanical stirring, such as polymethyl triethoxy, which is a series of silicone waterproofing agent products;

[0003] It is found in actual use that the existing reactor has the following deficiencies:

[0004] When solid materials are added, they tend to sink to the bottom and accumulate at the bottom valve of the kettle, resulting in a dead corner for stirring, causing incomplete reaction and affecting the yield of the product.

[0005] And when the reaction is finished and the material is discharged, due to the sedimentation of the materials, some materials accumulate and stick to the inner wall of the bottom valve of the kettle, which can easily cause the bottom valve of the kettle to be blocked and affect the smoothness of the discharge.

[0006] Therefore, the present application provides a nitrogen bubbling device for a bottom valve of a kettle with uniform stirring to meet the demand. Utility Model Content

[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a nitrogen bubbling device for a kettle bottom valve with uniform stirring.

[0008] The technical problem to be solved by the utility model is to provide a nitrogen bubbling device for a kettle bottom valve with uniform stirring so as to solve the problems of the existing nitrogen bubbling device for a kettle bottom valve with uniform stirring.

When the reaction is completed and the material is discharged, it can avoid the material sticking to the surface of the kettle bottom valve and causing blockage, making the discharge smoother.

[0022] 3. When the nitrogen passes through the bubbling holes of the disc-shaped distributor, the compressed airflow impacts the recoil block, causing the rubber recoil block to swell, and the recoil block moves left and right through the telescopic spring between the recoil block and the distributor. The recoil block can push the connecting rod and the cleaning block to move left and right, so that the cleaning block continuously moves in and out of the opening of the nitrogen delivery pipe. The shape of the circular cleaning block fits the nitrogen delivery pipe. The cleaning block can extend into the opening of the nitrogen delivery pipe to clean the inner wall of the nitrogen delivery pipe to avoid blockage at the opening of the nitrogen delivery pipe, effectively ensuring the normal output of nitrogen.

DETAILED DESCRIPTION

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model provides a uniformly stirred kettle bottom valve nitrogen bubbling device, comprising: a kettle body 1, a jacket 2, a feeding port 3, a kettle bottom valve 4, a nitrogen delivery pipe 5, a connecting flange 6, a limit seat 7, a connecting seat 8, a fixed bracket 9, a distributor 10, a recoil block 11, a telescopic spring 12, a connecting rod 13 and a cleaning block 14, the outer layer of the kettle body 1 is equipped with a jacket 2, the upper end of the kettle body 1 is equipped with a feeding port 3, the bottom of the kettle body 1 is equipped with a kettle bottom valve 4, and the side of the kettle bottom valve 4 is equipped with a nitrogen delivery Pipe 5, a connecting flange 6 is installed on the side of the nitrogen delivery pipe 5, a limiting seat 7 is installed on the surface of the side of the nitrogen delivery pipe 5 away from the connecting flange 6, a connecting seat 8 is installed on the side of the nitrogen delivery pipe 5 away from the connecting flange 6, a distributor 10 is installed on the outside of the connecting seat 8 through a fixed bracket 9, a recoil block 11 is installed on the side of the distributor 10, a telescopic spring 12 is installed on the inner surface of the recoil block 11, a connecting rod 13 is installed in the middle of the inner side of the recoil block 11, and a cleaning block 14 is installed on the other end of the connecting rod 13.

[0032] In this embodiment, the nitrogen delivery pipe 5 transversely penetrates the kettle bottom valve 4 and extends to the interior of the kettle bottom valve 4, and the connecting seat 8 is located inside the kettle bottom valve 4, connecting the nitrogen device with the connecting flange 6, and nitrogen can be passed from the nitrogen device into the kettle bottom valve 4 through the nitrogen delivery pipe 5.

[0033] In this embodiment, the connecting seat 8 is in a circular shape, and the connecting seat 8 is sleeved between the two groups of limit seats 7. The connecting seat 8 and the nitrogen delivery pipe 5 are movably connected. When the nitrogen is sprayed out horizontally from the nitrogen delivery pipe 5, it can promote the rotational flow of the liquid in the kettle bottom valve 4, thereby disturbing the materials deposited in the kettle bottom valve 4, preventing the solid materials from sinking to the bottom after feeding and accumulating at the kettle bottom valve 4, making the reaction more complete. The airflow and water flow are in contact with the distributor 10 opposite, so that the connecting seat 8 and the distributor 10 can move left and right along the nitrogen delivery pipe 5.

[0034] In this embodiment, the distributor 10 is disc-shaped, and the surface of the distributor 10 is evenly distributed with circular bubbling holes 1001 in a ring shape. When nitrogen is sprayed out horizontally from the nitrogen delivery pipe 5, the nitrogen passes through the disc-shaped distributor 10, causing the airflow and water flow to pass through the circular bubbling holes 1001 and form nitrogen bubbles. The nitrogen bubbles rise and burst in the liquid, completing the removal of dirt on the surface of the kettle bottom valve 4. When the reaction is completed and the material is discharged, it can avoid the material sticking to the surface of the kettle bottom valve 4 to cause blockage, making the discharge smoother.

[0036] In this embodiment, the recoil block 11 is arc-shaped and is made of rubber material. When the nitrogen passes through the bubbling hole 1001 of the disc-shaped distributor 10, the compressed airflow impacts the recoil block 11, causing the recoil block 11 made of rubber material to swell, and through the telescopic spring 12 between the recoil block 11 and the distributor 10, the recoil block 11 moves left and right.

[0037] In this embodiment, two groups of telescopic springs 12 are provided, and the two groups of telescopic springs 12 are transversely installed at the upper and lower ends of the recoil block 11 and the distributor 10 respectively.

[0038] In this embodiment, the connecting rod 13 extends from the middle of the distributor 10 horizontally to the opening of the nitrogen delivery pipe 5, and the cleaning block 14 is arranged opposite to the opening of the nitrogen delivery pipe 5. When the recoil block 11 moves left and right due to the impact force, it can push the connecting rod 13 and the cleaning block 14 to move left and right, so that the cleaning block 14 continuously enters and exits the opening of the nitrogen delivery pipe 5.

[0039] In this embodiment, the cleaning block 14 is in an annular shape, and the cleaning block 14 fits with the nitrogen delivery pipe 5. The shape of the annular cleaning block 14 fits with the nitrogen delivery pipe 5. The cleaning block 14 can be inserted into the opening of the nitrogen delivery pipe 5 to clean the inner wall of the nitrogen delivery pipe 5, thereby avoiding blockage at the opening of the nitrogen delivery pipe 5 and effectively ensuring the normal output of nitrogen.
