Abstract
The device is used for an external pipe joint structure of the concentrated sulfuric acid tank. The existing welding repair process has large preparation workload before repair; in the welding, digging and polishing processes of the empty and washed sulfuric acid tank, the risk of personal injury exists due to the fact that the metal residual hydrogen overflows and is easy to explode. The utility model comprises a concentrated sulfuric acid tank (1) and a joint (2), wherein the joint comprises a joint head (21), a locking nut (22) and a threaded sleeve (23), the threaded sleeve penetrates through a through hole of the concentrated sulfuric acid tank and is in threaded connection with the locking nut, and the joint head is in threaded connection with the threaded sleeve. The utility model is used for connecting the external pipe joint of the concentrated sulfuric acid tank.
Description
Technical Field
The utility model relates to an external pipe joint structure for a concentrated sulfuric acid tank.
Background
In the use process of the concentrated sulfuric acid tank of the industrial enterprise, the problems of system leakage, untight sealing, irregular connection and disconnection operations and the like cause a small amount of concentrated sulfuric acid leakage, absorb moisture in the air so as to generate corrosion phenomena on the drain outlet of the acid tank, the level meter and the like, and even cause the condition that an external pipeline falls off when serious.
Because the concentrated sulfuric acid tank is made of carbon steel, the inner wall of the acid tank still contains a large amount of hydrogen after flushing, the existing sulfuric acid tank repairing process mainly comprises metal polishing and manual welding, and the existing welding repairing process has large preparation workload before repairing; in the welding, digging and polishing processes of the empty and washed sulfuric acid tank, the risk of personal injury exists due to the fact that the metal residual hydrogen overflows and is easy to explode.
Disclosure of Invention
The utility model aims to solve the problems and provide an external pipe joint structure for a concentrated sulfuric acid tank.
The above object is achieved by the following technical scheme:
the utility model provides a be used for concentrated sulfuric acid tank external connection pipe joint structure, its constitution includes concentrated sulfuric acid tank and connects, the joint include connector, lock nut and screw sleeve, screw sleeve pass behind the through-hole of concentrated sulfuric acid tank with lock nut threaded connection, the connector with screw sleeve threaded connection.
The external pipe joint structure for the concentrated sulfuric acid tank is characterized in that the threaded sleeve is a hollow cylinder with internal threads and external threads, and a sealing step is arranged in the threaded sleeve.
The external pipe joint structure for the concentrated sulfuric acid tank is characterized in that the connector is a hollow cylinder with a flange plate, and the end face of the hollow cylinder is provided with a sealing ring.
Advantageous effects
1. According to the utility model, the drain outlet of the sulfuric acid tank is repaired through the joint structure, and the external pipeline is directly connected with the joint. The sulfuric acid tank body is repaired through the structure without repeated flushing and long-time empty acid tank, so that the preparation work before repair is reduced, the repair period is shortened, meanwhile, the repair process is safe, explosion and personal injury risks are avoided, the sulfuric acid tank body is used for a long time after repair without corrosion and leakage, and the effective guarantee is provided for long-term safe and stable operation of sulfuric acid equipment.

FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic structural view of a joint;
FIG. 3 is a schematic view of the structure of a threaded sleeve;
in the figure: 1. a concentrated sulfuric acid tank; 2. a joint; 21. a connector; 22. a lock nut; 23. a threaded sleeve; 24. a liquid through hole; 25. a seal ring; 26. sealing the step.
Detailed Description
Referring to fig. 1-3, an external pipe joint structure for a concentrated sulfuric acid tank comprises a concentrated sulfuric acid tank 1 and a joint 2, wherein the joint comprises a joint head 21, a locking nut 22 and a threaded sleeve 23, the threaded sleeve penetrates through a through hole of the concentrated sulfuric acid tank and is in threaded connection with the locking nut, and the joint head is in threaded connection with the threaded sleeve.
The threaded sleeve is a hollow cylinder with internal threads and external threads, and a sealing step 26 is arranged in the threaded sleeve;
the connector is a hollow cylinder with a flange, the end face of the hollow cylinder is provided with a sealing ring 25, and the connector is provided with a step matched with a sealing step on the threaded sleeve;
working principle: the connector, lock nut and screw thread sleeve of this device select for use polytetrafluoroethylene material, and the sealing washer is acid and alkali-resistant FFKM perfluoroether sealing washer, during the use, wears out the screw thread sleeve from the drain of the concentrated sulfuric acid tank after washing, tightens up lock nut and realizes locking, then accomplishes the installation of device with connector and screw thread sleeve threaded connection, is connected with external pipe through the ring flange when connecting the takeover outward, like this when carrying out the blowdown, concentrated sulfuric acid passes through screw thread telescopic logical liquid hole 24 and then discharges through the connector, can realize the quick repair to concentrated sulfuric acid tank drain.
