Description

Technical Field

[0001] This utility model relates to the field of acid cooler technology, specifically to a manhole structure for an acid cooler that requires no handling. Background Technology

[0002] Dry-absorption acid coolers are one of the most important pieces of equipment in sulfuric acid production, and they are also the most difficult to handle when leaks occur during the sulfuric acid production process. Due to reasons such as substandard medium and circulating water quality, acid coolers may be corroded or leak from their structure.

[0003] When dealing with leaks inside the acid cooler, it is necessary to remove the water-side sealing blind flange. Large acid coolers have large blind flanges, making removal labor-intensive and time-consuming. Furthermore, the weight of the blind flange makes removal difficult, and there is a risk of damaging the cathode wires during removal or installation. The numerous bolts used for removing and sealing the blind flange also result in lengthy assembly and disassembly times, requiring significant manual labor and leading to low efficiency. Therefore, we propose a transport-free manhole structure for the acid cooler. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenient maintenance and heavy blind plates that are difficult to disassemble, and to provide a manhole structure for an acid cooler that does not require handling.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A manhole structure for a portable acid cooler includes an acid cooler tube body. Tube box heads are fixedly installed at both ends of the acid cooler tube body. A manhole device is provided on the outer wall of the tube box heads. The manhole device includes an inspection hole located on the side wall of the tube box heads. A base is fixedly installed on the outer wall of the inspection hole. A rotating shaft is fixedly installed on the outer wall of the base away from both ends of the acid cooler tube body. A manhole cover is rotatably installed on the outer wall of the rotating shaft. Several fixing seats are fixedly installed on the outer wall of the base, and several fixing bases are fixedly installed on the outer wall of the manhole cover. A docking seat, and several T-shaped locking seats are respectively installed through and rotatably on the inner walls of several fixed seats. Several fastening knobs are respectively threaded to the outer walls of the ends of the T-shaped locking seats away from the fixed seats. A limiting seat is fixedly installed at the top of the manhole cover away from the outer wall of the inspection hole. A threaded rod is threaded to the inner wall of the limiting seat. A handle is fixedly installed at the end of the threaded rod away from the inspection hole. A blind plate is fixedly installed at the end of the threaded rod near the inspection hole. A C-shaped sealing ring is fixedly installed on the outer side of the blind plate near the inspection hole.

[0007] Preferably, the outer wall of the manhole cover is provided with a handle, the docking seat is provided with a notch, and the T-shaped restraining seat corresponds one-to-one with the notch on the docking seat.

[0009] By employing the above technical solution, this utility model provides a manhole structure for an acid cooler that eliminates the need for handling. The beneficial effects are: this utility model achieves a perfect seal between the blind flange, the acid in the acid cooler tube, and the manhole cover through a C-shaped sealing ring made of acid-resistant rubber; the added manhole device enables handling-free operation, significantly solving the problems of heavy and difficult-to-disassemble traditional blind flanges, and avoiding the risk of damaging the cathode wire during disassembly; at the same time, it greatly reduces labor intensity and man-hours, shortens production downtime, and improves production efficiency and safety.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] A manhole structure for a portable acid cooler, such as Figures 1-3As shown, the device includes an acid cooler tube body 1, with tube box end caps 11 fixedly installed at both ends. A manhole device 2 is provided on the outer wall of the tube box end caps 11, including an inspection hole 21 located on the side wall of the tube box end caps 11. A base 22 is fixedly installed on the outer wall of the inspection hole 21. A rotating shaft 23 is fixedly installed on the outer wall of the base 22 away from both ends of the acid cooler tube body 1. A manhole cover 24 is rotatably installed on the outer wall of the rotating shaft 23. Several fixing seats 25 are fixedly installed on the outer wall of the base 22, and several docking seats 26 and fixing seats 25 are fixedly installed on the outer wall of the manhole cover 24. Several T-shaped locking seats 27 are installed through and rotatably on the inner wall of the manhole cover 24. Several fastening knobs 28 are threadedly connected to the outer wall of the T-shaped locking seats 27 away from the fixed seat 25. A limiting seat 29 is fixedly installed at the top of the outer wall of the manhole cover 24 away from the inspection hole 21. A threaded rod 210 is threadedly connected to the inner wall of the limiting seat 29. A handle 211 is fixedly installed at the end of the threaded rod 210 away from the inspection hole 21. A blind plate 212 is fixedly installed at the end of the threaded rod 210 near the inspection hole 21. A C-shaped sealing ring 213 is fixedly installed on the outer side of the blind plate 212 near the inspection hole 21.

[0018] The outer wall of the manhole cover 24 is provided with a handle, and the docking seat 26 is provided with a notch. The T-shaped locking seat 27 corresponds one-to-one with the notch on the docking seat 26.

[0019] The blind flange 212 fits the inner diameter of the base 22, and the C-shaped sealing ring 213 is made of acid-resistant rubber.

[0020] In the present invention, a manhole structure for a portable acid cooler is provided. When a leak occurs inside the acid cooler tube 1, existing technology typically involves removing the blind sealing plate 212, which is labor-intensive and inconvenient. To address this issue, if access to the acid cooler is required, a blower is installed at the inspection port 21 on the non-working end to remove water vapor from inside the acid cooler tube 1. After removing the water vapor, the handle 211 is rotated, causing the threaded rod 210 to move against the limiting seat 29. The inner wall rotates outward, and the threaded rod 210 drives the blind plate 212 to rotate outward on the inner wall of the base 22. The threaded rod 210 stops after rotating to the top. Through the inspection hole 21, the fastening knob 28 surrounding the outside of the manhole cover 24 is rotated. The fastening knob 28 rotates outward on the outer wall of the T-shaped locking seat 27 away from the base 22, so that the T-shaped locking seat 27 rotates and leaves the notch of the docking seat 26. Pull the handle on the manhole cover 24 outward, thereby completing the separation of the manhole cover 24 from the base 22. The operator can then enter through the inspection hole 21 at the working end to handle the fault.

[0021] After the maintenance is completed, repeat the above operations. Rotate the blind flange 212 to the bottom inner wall of the base 22, and then cover it with the manhole cover 24. The C-shaped sealing ring 213 made of acid-resistant rubber can perfectly seal the blind flange 212, the acid cooler tube 1, and the manhole cover 24. The added manhole device 2 enables hands-free operation, which significantly solves the problem of the traditional blind flange 212 being heavy and difficult to disassemble, and avoids the risk of damaging the cathode wire during disassembly. At the same time, it greatly reduces labor intensity and man-hours, shortens the time affected by production, and improves production efficiency and safety factor.
