DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0030] Reference Figure 1-6 A detection reactor for petrochemical industry comprises a reactor body 1, a feeding pipe 2 is arranged on the top of the reactor body 1, materials are added into the reactor body 1 through the feeding pipe 2 and react inside the reactor body 1, a discharge pipe 3 is arranged on one side of the bottom of the reactor body 1, and the reacted materials are discharged from the discharge pipe 3. Both the feeding pipe 2 and the discharge pipe 3 are equipped with valves.

[0031] If gas is generated during the reaction, it can be discharged from the feeding pipe 2, or detected and collected using existing detection equipment.

[0032] A plurality of pillars 4 are installed around the bottom of the kettle body 1, and the pillars 4 support the entire kettle body 1 so that its bottom is separated from the ground. A first motor 5, a second motor 6 and a water pump 7 are installed on the upper side of the kettle body 1. A rotating shaft 9 located inside the kettle body 1 is installed at the driving end of the first motor 5, and a plurality of stirring rods 10 are installed on the rotating shaft 9.

[0033] The first motor 5 drives the rotating shaft 9 and the stirring rod 10 to rotate, so as to mix and stir the materials inside the kettle body 1.

[0034] There are four second motors 6, and the driving end of the second motor 6 is installed with a threaded rod 15 located inside the kettle body 1, and each threaded rod 15 is threadedly installed with a slider with a hole, and the slider with a hole 16 is installed together with a cleaning ring 17, and an annular tube 18 is installed on the upper side of the cleaning ring 17. In this embodiment, the annular tube 18 is installed on the upper side of the cleaning ring 17 by means of multiple vertical poles.

[0035] A plurality of spray pipes 22 are installed on the outer sides of the annular pipe 18 . A hose 8 is installed on the annular pipe 18 . The hose 8 is installed with the water outlet of the water pump 7 .

[0036] The second motor 6 drives the corresponding threaded rod 15 to rotate. The threaded cooperation between the threaded rod 15 and the perforated slider 16 can cause the cleaning ring 17 and the annular tube 18 to move up and down together. The cleaning ring 17 cleans the scale adsorbed inside the kettle body 1 through friction. At the same time, the water pump 7 supplies water to the hose 8, the annular tube 18 and the nozzle 22. The sprayed water flow can wash the scale on the inner wall of the kettle body 1 and make it fall to the bottom.

[0037] A perforated plate 12 is installed on the inner wall of the kettle body 1 near the bottom, and a plurality of through holes are opened in the perforated plate 12. A lifting sealing frame 13 is provided on the lower side of the perforated plate 12. The lifting sealing frame 13 is lifted and installed on the inner wall of the bottom of the kettle body 1 through an electric lifting rod 14. The lifting sealing frame 13 includes sealing columns 21, and the sealing columns 21 correspond to the through holes of the perforated plate 12 one by one.

[0038] When the material reacts, the lifting sealing frame 13 is kept at a high position by the electric lifting rod 14. At this time, the sealing column 21 therein just blocks the through hole of the perforated plate 12, thereby sealing the perforated plate 12, and the reacted material is discharged from the kettle body 1 through the discharge pipe 3.

[0039] After the reaction, and when cleaning the scale in the kettle body 1, the lifting sealing frame 13 falls to a low position through the action of the electric lifting rod 14, at which time the sealing column 21 leaves the through hole, and the scale and sewage can flow out of the kettle body 1 through the through hole for discharge.

[0040] A slide groove is vertically provided on the inner side wall of the kettle body 1 , the threaded rod 15 and the sliding block 16 with holes are both located in the slide groove, and the outer side wall of the cleaning ring 17 is in friction contact with the inner side wall of the kettle body 1 .

[0041] The lifting sealing frame 13 further includes a plurality of annular rods 19 with different diameters. The annular rods 19 are connected and fixed to each other via a plurality of supporting rods 20 . The sealing columns 21 are installed on the upper sides of the annular rods 19 .

[0042] The structural composition characteristics of the lifting sealing frame 13 can avoid affecting the normal discharge of scale and sewage when it is lowered to a low point.

[0043] There are multiple stirring rods 10, and the length of each stirring rod 10 is smaller than the radius of the cleaning ring 17 and the annular tube 18. The stirring rod 10 will not collide with the cleaning ring 17 and the annular tube 18 when rotating. Example

[0044] The second embodiment is based on the first embodiment: a plurality of cleaning plates 11 are installed at the bottom end of the rotating shaft 9, the cleaning plates 11 are in the shape of strip plates, and the bottom wall of the cleaning plates 11 is in frictional contact with the top wall of the perforated plate 12. The length of the cleaning plates 11 is smaller than the radius of the cleaning ring 17 and the annular tube 18. The cleaning plates 11 will not collide with the cleaning ring 17 and the annular tube 18 when rotating.

[0045] The cleaning plate 11 can rotate along with the rotating shaft 9 to clean the perforated plate 12 to ensure its cleanliness, avoid clogging of the perforated plate 12, and ensure that the scale in the kettle body 1 can be discharged smoothly and thoroughly.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
