Description

Technical Field

[0001] The utility model belongs to the technical field of reactor design, in particular to a protective structure of a reactor. Background Art

[0002] A reactor is a comprehensive reaction vessel, with its structure, functions, and accessories designed according to reaction conditions. From feeding to reaction to discharging, pre-set reaction steps can be completed with a high degree of automation, with strict control over key parameters such as temperature, pressure, mechanical control (stirring, ventilation, etc.), and reactant / product concentrations. Its structure generally consists of a reactor body, transmission device, stirring device, heating device, cooling device, and sealing device.

[0003] At present, a Chinese patent with publication number CN221656549U and publication date September 6, 2024 discloses a reactor for the production of chromium formate, including: a reactor tank body and a drain valve installed under the reactor tank body, and a hard pipe is installed on one side of the drain valve, and a pump body is installed at the tail end of the hard pipe; a collecting mechanism is provided on one side of the pump body, and a base is installed at the bottom of the pump body; the collecting mechanism includes a waste box and a fixed plate, a water inlet is provided on the top of the waste box, the water inlet is connected to the pump body through a material guide pipe, a slide is provided on the front of the waste box, and both ends of the fixed plate are fixedly connected to a limit block and a slider, the limit block is slidably connected to the slide, and a filter is installed on the upper end of the fixed plate, and a cleaning part is provided inside the waste box.

[0004] During the long-term use of the reactor, the sealing performance of the connection structure at the drain valve position will become increasingly poor, which may result in leakage at the connection between the drain valve and the reactor. Furthermore, since the chemical substances in the reactor may be highly corrosive and chemically toxic, once they come into contact with the operator, they may easily endanger the operator's personal safety. Utility Model Content

[0005] The utility model aims to provide a protective structure for a reactor, which can collect leaked chemical substances when leakage occurs.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a protective structure for a reactor, comprising a foundation installed at the lower end of the reactor, a floor for installing the upper end of the reactor, and four columns arranged on the periphery between the foundation and the floor and located on the periphery of the reactor. A square annular groove is provided on the upper surface of the foundation and located on the periphery of the reactor, a supporting mesh plate is provided on the upper side of the annular groove, a sewage pipe is provided on one side of the foundation, one end of the pipe is connected to the annular groove and the other end is connected to the wastewater treatment tank, and a plurality of protective cloth strips evenly spaced in the vertical direction are provided between two adjacent columns.

[0007] The present invention is further configured as follows: movable columns for connecting the ends of multiple protective cloth strips are provided on the sides of the columns, and connecting pieces for detachably connecting the two movable columns are provided between the two adjacent columns.

[0008] The utility model is further configured as follows: a long groove for the protective cloth strip to pass through is opened in the side of the column, a cylindrical groove which is connected to the long groove and has a circular cross-section is opened in the column, a connecting shaft for connecting multiple protective cloth strips away from one end of the movable column is rotatably connected in the cylindrical groove, the upper end of the connecting shaft is sleeved with a return torsion spring which has one end welded to the connecting shaft and the other end welded to the inner wall of the cylindrical groove, and a shaft sleeve for the lower end of the connecting shaft to be embedded in is provided in the lower end of the cylindrical groove.

[0009] The utility model is further configured as follows: the connecting member includes a connecting block arranged on a movable column on one side, a connecting column arranged on a movable column on the other side, a card slot opened in the connecting block and the upper end of which is communicated with the outside world, an open groove opened on the outer wall of the connecting block and communicated with the card slot, and a card head arranged at one end of the connecting column away from the movable column and used to be embedded in the card slot, and the open groove is U-shaped and the width is equal to the cross-sectional diameter of the connecting column.

[0010] The present invention is further configured as follows: a plurality of the connecting blocks and connecting columns are provided and are evenly spaced and distributed along the extension direction of the movable column.

[0011] The utility model is further configured as follows: an anti-corrosion coating is coated on the upper surface of the foundation.

[0012] In summary, the present invention has the following beneficial effects:

[0013] 1. When the liquid in the reactor leaks, the square annular groove on the upper surface of the foundation and located around the reactor will collect the leaked liquid into the annular groove and then be discharged to the wastewater treatment tank through the sewage pipe. The support mesh plate on the upper side of the annular groove is for people to step on, so as to prevent operators from stepping on empty space in the annular groove. Finally, the leaked chemical substances can be collected in the event of a leak.

[0014] At the same time, the columns are used to support and protect the sides of the reactor. Multiple protective cloth strips are set between two adjacent columns to surround the sides of the reactor, thereby isolating the reactor and preventing passers-by from accidentally entering the reactor and touching the leaked liquid. Since the outer wall of the reactor is still hot, the protective cloth strips can also reduce the possibility of people touching the outer wall of the high-temperature reactor, which is conducive to reducing the occurrence of scalding accidents.

[0015] 2. When the protective cloth strip needs to be opened, the two movable columns can be separated after the connector is disassembled, thereby quickly opening the protective cloth strip;

[0016] 3. After the two movable columns are separated, the elastic restoring force of the return torsion spring drives the connecting shaft to rotate, thereby reeling in the multiple protective cloth strips through the connecting shaft until the movable column abuts against the outside of the long slot. At this point, the protective cloth strips are reeled into the column. Moving the movable column away from the column drives the connecting shaft to rotate in the opposite direction, and the return torsion spring elastically contracts again, unwinding the protective cloth strips from the connecting shaft.

[0017] 4. When you need to connect two moving columns together, insert the clamp on one moving column into the clamping slot on the other moving column from top to bottom. This will quickly connect the two moving columns.

[0018] 5. By providing multiple connection blocks and connection columns and evenly distributing them along the extension direction of the movable column, the connection of multiple connection blocks and connection columns can facilitate the stable connection between the two movable columns;

[0019] 6. Utilize the anti-corrosion coating applied on the upper surface of the foundation, the anti-corrosion coating can protect the foundation and prevent the liquid leaking on the upper surface of the base from corroding the foundation. BRIEF DESCRIPTION OF THE DRAWINGS
