Technical Field

[0001] The utility model relates to the technical field of reaction kettles, and particularly relates to an anti-corrosion base of a sampling device for a reaction kettle. Background Art

[0002] In industries such as chemical engineering, pharmaceuticals, and food, reaction kettles are used as reaction containers or devices. In order to detect the reaction degree in the reaction kettle and judge the reaction end point, sampling and analysis are required during the production process. There are generally two sampling methods. One is the traditional direct sampling from the sampling ports left at the upper or lower part of the reaction kettle, and the other is sampling using the vacuum principle. Most of the existing sampling devices are applicable to non-corrosive scenarios. The sampling devices for corrosive scenarios have complex structures, large processing difficulties, small application ranges, and poor protection capabilities for strongly corrosive media. Therefore, it is urgent to design a sampling device that can overcome the above defects. The existing sampling device includes a base, a sampling pipe, and a valve group pipeline. If it is to be applicable to corrosive scenarios, at least the base and the sampling pipe need to be applicable to corrosive scenarios. Content of the Utility Model

Detailed implementation manners

[0024] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] Such as Figures 1-4As shown in the figure, this embodiment provides an anti-corrosion base for a reactor sampling device, which includes a base 1 and a sampling inner tube 2. A first groove 11 is provided at the top of the base 1, and a first flange 21 is provided on the circumferential side of the top of the sampling inner tube 2. The first flange 21 is adapted to the first groove 11. The first flange 21 is installed in the first groove 11 and fixed by a connecting member (such as a bolt) so that the sampling inner tube 2 and the base 1 can be fixed as a whole. A first through hole 12 communicating with the bottom surface of the base 1 is provided at the bottom of the first groove 11. The upper part of the sampling inner tube 2 is inserted into the first through hole 12, and the lower end of the sampling inner tube 2 extends out of the first through hole 12. Generally, the length of the sampling inner tube 2 is determined according to the liquid level height in the reactor. The base 1 is a plastic base, and the sampling inner tube 2 is a metal tube (such as a stainless steel tube) with plastic anti-corrosion layers provided on the inner and outer sides of the metal tube.

[0026] By using the base 1 made of plastic material and the sampling inner tube 2 formed by wrapping a plastic anti-corrosion layer around a metal tube, it can adapt to the vast majority of corrosive scenarios and has a wide applicability. The sampling inner tube 2 formed by wrapping a plastic anti-corrosion layer around a metal tube has greatly improved strength compared with a plastic tube, can adapt to vibrating scenarios, will not be bent, and has high durability. The base 1 is provided with a first through hole 12, and the sampling inner tube 2 is inserted into the first through hole 12. In this way, through a special structural design, it can be conveniently connected to the upper suction pipe and the right return pipe.

[0027] In this embodiment, the base 1 is further provided with a plurality of vertical second through holes 13, and the plurality of second through holes 13 are evenly distributed around the circumference of the first groove 11. Generally, the number and positions of the second through holes 13 correspond to the bolt holes or through holes of the flange interface at the top of the reactor; the second through holes 13 also correspond to the through holes on the flange of the suction pipe. In this way, the base 1 can be fixed to the reactor and can also be connected to the suction pipe; the suction pipe is communicated with the reactor through the sampling inner tube 2.

[0028] In this embodiment, a plurality of first bolt holes 14 are further provided at the bottom of the first groove 11, and the plurality of first bolt holes 14 are evenly distributed around the circumference of the first through hole 12; a plurality of third through holes 22 are provided on the first flange 21, and the plurality of third through holes 22 are provided in one-to-one correspondence with the plurality of first bolt holes 14. The third through holes 22 are used for inserting connecting members such as bolts so as to fix the first flange 21 in the first groove 11 by using bolts, and further fix the sampling inner tube 2 and the base 1.

[0029] In this embodiment, the first flange 21 and the metal tube are integrally formed. Therefore, the material of the first flange 21 is the same as that of the metal tube. The integral formation of the first flange 21 and the metal tube can improve the connection strength between the two.

[0030] In this embodiment, the anti-corrosion base further includes a sampling outer tube 15. The sampling outer tube 15 is vertically arranged at the bottom of the base 1. The sampling outer tube 15 is sleeved outside the sampling inner tube 2, and an annular channel is provided between the sampling outer tube 15 and the sampling inner tube 2. A fourth through hole 17 communicating the annular channel and the outer space on the side of the base 1 is provided on the side of the base 1. Generally, the length of the sampling outer tube 15 is determined according to the liquid level height in the reactor. After installation, the lower end of the sampling inner tube 2 is closer to the bottom of the reactor than the lower end of the sampling outer tube 15. The inner diameter of the sampling outer tube 15 should be larger than the outer diameter of the sampling inner tube 2 to form an annular channel. The fourth through hole 17 is used as a reflux hole to connect the reflux pipeline and the annular channel, so that the material can flow back to the reactor.

[0031] In this embodiment, the base 1 and the sampling outer tube 15 are integrally formed. Since the base 1 is made of plastic material, the sampling outer tube 15 is also made of plastic material. The integral formation of the base 1 and the sampling outer tube 15 can improve the connection strength between the two.

[0032] In this embodiment, a convex platform 16 protrudes from the side of the base 1. The convex platform 16 is provided with a second groove 18, and the fourth through hole 17 is located at the center of the second groove 18. The second groove 18 is used to install the flange of the reflux pipeline. Therefore, the second groove 18 is adapted to the flange of the reflux pipeline. A plurality of second bolt holes 19 are provided at the bottom of the second groove 18, and the plurality of second bolt holes 19 are evenly arranged around the circumference of the fourth through hole 17. It should be noted that the second bolt holes 19 correspond to the through holes on the flange of the reflux pipeline. In this way, the base 1 and the reflux pipeline can be fixed by bolts and other connecting parts, and the reflux pipeline is communicated with the reactor through the fourth through hole 17 and the annular channel.
