Description

Technical Field

[0001] The invention relates to the technical field of anti-collision devices, in particular to an anti-collision device for a sampling port of a water washing kettle. Background Art

[0002] In chemical production, it is often necessary to extract materials from a water washing kettle for testing. The inner surface of existing water washing kettles is coated with enamel. The current sampling method is to use an iron or steel sampling bucket to take samples from a sampling port deep into the water washing kettle. The enamel around the sampling port is often damaged during sampling, which will directly affect the water washing kettle and even cause the water washing kettle to be scrapped.

[0003] To this end, a Chinese patent with publication number "CN202793849U" announced "a water washing kettle sampling port anti-collision device", whose main structure includes a water washing kettle and a sampling port on the water washing kettle, an elastic anti-collision sleeve is arranged in the sampling port, the anti-collision sleeve and the sampling port are tightly fitted, an annular boss is arranged on the upper edge of the anti-collision sleeve, and a plug is inserted in the anti-collision sleeve. In the water washing kettle sampling port anti-collision device, the boss prevents the anti-collision sleeve from entering the water washing kettle due to external forces, and avoids the enamel layer on the inner surface of the sampling port in actual use, thereby protecting the water washing kettle.

[0004] However, in actual use, after a single sampling is completed, the sampling port of the water washing kettle needs to be closed. Therefore, the anti-collision sleeve needs to be taken out after use, and needs to be installed in the sampling port when in use. Since some chemical liquid will remain in the anti-collision sleeve during the sampling process, it is necessary to be careful when taking and placing the anti-collision sleeve. The above-mentioned anti-collision device for the sampling port of the water washing kettle does not have effective personnel protection measures for taking and placing the anti-collision sleeve, and there is a great safety hazard.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A collision prevention device for a sampling port of a water washing kettle is fixedly installed on the surface of a kettle body of a reactor. In order to realize an adsorption-type fixed connection with the reactor body, a vacuum adsorption mechanism 1 is required, wherein a first longitudinal hollow shell 11 with a hollow structure is arranged inside the vacuum adsorption mechanism 1, an embedded ring body 110 partially placed in the first longitudinal hollow shell 11 and capable of longitudinally moving relative to the first longitudinal hollow shell 11, and an annular sealing ring 111 embedded in the bottom of the embedded ring body 110 and capable of being adsorbed and fixed on the surface of the kettle body near the sampling port of the reactor after the gas inside the first longitudinal hollow shell 11 is extracted, and the annular sealing ring 111 is pressed against the surface of the kettle body at the installation position.

[0029] For the specific structure of the vacuum adsorption mechanism 1, please refer to Figure 3 and Figure 4 , comprising a No. 1 longitudinal hollow shell 11, the top of which is provided with a gas flow channel 112 which is connected to a No. 1 cylindrical cavity 12 and has a gas valve installed inside, the interior of the No. 1 longitudinal hollow shell 11 is provided with a No. 1 cylindrical cavity 12 with an open bottom end, the center of the No. 1 longitudinal hollow shell 11 is provided with a longitudinal inner hollow tube structure 13, the top of the inner hollow tube structure 13 is provided with a top docking plate 14 of an integrated structure, and the interior of the inner hollow tube structure 13 is provided with a No. 2 cylindrical cavity 15 with an open top end.

[0039] When in use, the annular sealing ring 111 is pressed against the surface of the kettle body at the installation position, and the No. 1 longitudinal hollow shell 11 is pressed downward, and then a vacuum device is required to extract the gas from the inside of the No. 1 cylindrical cavity 12, and the inside of the No. 1 cylindrical cavity 12 forms a vacuum state. At this time, the annular sealing ring 111 forms an adsorption phenomenon on the kettle body, and the No. 1 longitudinal hollow shell 11 will move downward relatively, and the No. 1 coil spring 113 will be compressed. The compressed No. 1 coil spring 113 forms a downward elastic pressure on the annular sealing ring 111, so that the annular sealing ring 111 is stably adsorbed on the surface of the kettle body, and after installation, when the transverse When the limit rod 210 is inserted into the limit groove 28 of the No. 1 rod body, the anti-collision sleeve 34 extends into the sampling port of the reactor.
