Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pressure vessels, and particularly relates to a discharge device for a lined pressure vessel. Background Art
[0002] As pressure vessels become larger and hotter, in order to prevent the internal temperature of the equipment from being too high and affecting the material properties of the metal shell, cast lining or masonry lining is generally used to protect the metal shell. Among them, the reaction equipment needs to be filled with bulk fillers because of the need for medium reaction, and a discharge hole needs to be set at the bottom of the filler section. The discharge hole includes a discharge hole pipe, a flange and a flange cover. The outside of the discharge hole is sealed with bolts through flange 2 and the flange cover, which is convenient for replacing the filler. For ordinary discharge holes, a cylindrical pier is integrally cast at the discharge hole to block the discharge hole. Because the cylindrical pier is very heavy, it is not only very difficult to disassemble and assemble, but also the cylindrical pier is very likely to cause a safety accident of injuring the operator when removing the filler. Therefore, it is of great practical significance to adopt a discharge hole device for pressure vessels with linings. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a unloading device for a lined pressure vessel, which has a simple and compact structure, not only ensuring the original thermal insulation protection effect, but also saving time and effort during unloading operation, and at the same time there is no safety hazard of being hit.
[0004] The utility model is realized by adopting the following technical solutions:
[0005] A discharge device for a lined pressure vessel comprises at least one stopper and at least one casting block, wherein the stopper is fixed to the inner wall of a discharge hole pipe, the casting block comprises a cylinder with a bottom cover and a nut fixed to the outer side of the bottom cover, casting material is cast inside the cylinder, and the outer wall of the cylinder is provided with a longitudinal groove for the stopper to pass through.
[0006] When installing the casting block: after the longitudinal groove of the casting block and the position of the stopper correspond to each other, push the casting block into the discharge hole, rotate the nut at the bottom of the casting block to drive the casting block to rotate, so that the longitudinal groove on the casting block and the position of the stopper are staggered to ensure that the casting block does not fall out, and then repeat the above steps to push in the next casting block. The same applies when disassembling the casting block.
[0007] Further preferably, it also includes a handwheel, a stud with a matching nut is fixed on one side of the handwheel to facilitate the rotation of the nut. When in use, after the stud of the handwheel is screwed into the nut, the handwheel is continued to be screwed to drive the nut to continue rotating, and the nut drives the casting block to rotate.
[0008] Further preferably, in order to make the casting block more securely blocked by the block, the number of the block is 3, which are evenly distributed on the inner wall of the discharge hole pipe close to the outer side, and the number and position of the longitudinal grooves correspond one-to-one to the block.
[0009] Further preferably, the casting block further comprises anchoring nails, and the anchoring nails are fixed on the inner side of the bottom cover of the cylinder, so that the casting material and the cylinder can be integrated, making it convenient to remove the casting material.
[0010] Compared with the prior art, the unloading device provided by the utility model is not only light in weight and convenient for disassembly and assembly, but also can adopt casting blocks of corresponding casting materials of the lining, thereby ensuring the correspondence between the unloading hole and the casting material of the pressure vessel lining, and can save the casting material cost.

[0022] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0023] A discharge device for a lined pressure vessel includes three blocks 3 and three casting blocks 4. The blocks 3 can be evenly distributed at 120° and welded to the inner wall of the discharge hole pipe 5 near the outer side. Preferably, the material of the blocks 3 is the same as that of the inner wall of the discharge hole pipe 5.

The casting block 4 also includes an anchor nail 43, which is fixed to the inner side of the bottom cover of the cylinder 41. When the casting material is poured, an expansion hole is reserved in the center to prevent the casting material from expanding and cracking. After the casting material is formed, the central expansion hole is filled with refractory fiber felt 9.
[0025] A discharge device for a lined pressure vessel also includes a hand wheel 1, and a stud with a matching nut 44 is fixed on one side of the hand wheel 1 for rotating the casting block 4.

The same principle can be applied when removing the casting block 4.
[0029] Preferably, Figure 1 As shown, the spaces between the casting blocks 4 in the discharge hole, the central expansion hole of the casting block 4, and the position of the hand wheel 1 are all filled with refractory fiber felt 9, and then the outer side of the discharge hole is sealed with flange 2 and flange cover by bolts.
[0030] The utility model has the following advantages:
[0031] 1. The casting block 4 is formed by combining multiple pieces according to the actual thickness of the pressure vessel lining castable. It is not only light in weight and convenient for disassembly and assembly, but also the multi-layer castable lined pressure vessel can use the casting block 4 of the corresponding castable, ensuring the correspondence between the lining pressure vessel and the casting block 4, saving costs.
[0032] 2. There are expansion holes inside the casting block 4 to prevent the casting material from drying, expanding and cracking.
[0033] 3. Anchoring nails 43 are arranged inside the casting block 4 to ensure the integrity of the casting block 4.
[0034] 4. There is a nut 44 at the center of the baffle of the casting block 4, and the hand wheel 1 can be screwed into the nut 44 to rotate the casting block 4.
[0035] 5. There are three evenly distributed grooves on the outer periphery of the casting block 4, and the casting block 4 can smoothly pass through the three evenly distributed stoppers 3 by rotating the hand wheel 1.
