Abstract
The utility model discloses a water cap for a shell and tube reactor, which comprises a water cap plug (1), a water cap end tube (2) and a water cap winding wire (3). The utility model is characterized in that the water cap plug (1) is composed of a lug boss (4) and an external thread part (5); the water cap end tube (2) is composed of an internal thread part (6) and a lug boss (7); the water cap winding wire (3) is composed of a titanium ring (8), a titanium winding wire (9) and a titanium plate (10); the water cap winding wire (3) is sheathed in the water cap end tube (2); and the threaded connection of the water cap plug (1) and the water cap end tube (2) fixes the water cap winding wire (3). In the utility model, the water cap plug is separated from the water cap winding wire, and thus, the titanium winding wire can not become loosened and the water cap can not be damaged in the detaching process of the water cap, thereby solving the problem of difficulty in detaching the water cap; and meanwhile, the inside of the water cap winding wire can be cleaned more easily.
Description
Technical field
The utility model relates to a kind of shell and tube reactor water cap, and particularly a kind of acetate product that is used for is produced used shell and tube reactor water cap.
Background technology
Because wrapping wire is simple in structure, circulation is relatively large, processes also fairly simplely, and the most of wrapping wire that adopts of existing acetic acid esters shell and tube reactor water cap processes.Yet existing water cap is generally formed by water cap wrapping wire that has capstan nut and water cap end pipe, and the water cap wrapping wire that has capstan nut wherein comprises capstan nut, band male thread portion, titanium wrapping wire and titanium plate.Wherein, Capstan nut, band male thread portion, titanium wrapping wire all adopt welding manner to be connected with the titanium plate; And water cap end pipe racks has internal thread; The water cap wrapping wire that will have a capstan nut is through being threaded and water cap end pipe couples together, and then water cap end pipe is fixed on the two ends of reactor tubulation through the mode of welding.Though this water cap is simple in structure, handling ease, the problem below existing: 1, nut is welded on the water cap, the water cap is not easy dismounting, and more painstaking when unloading the water cap, operating efficiency is low; 2, defocused when catalyst junction, because catalyst stops up the gap of water cap and reaction tube live, can cause the titanium wrapping wire to scatter when unloading the water cap through rotation, cause the damage of water cap; 3, these each parts of water cap wrapping wire that have capstan nut clean also very difficulty owing to all adopt the connected mode of welding so have the inside of the water cap wrapping wire of capstan nut.
Summary of the invention
The utility model solves can above problem, and a kind of dismounting that is easy to is provided, and is difficult for damage and easy cleaned shell and tube reactor water cap in the process of dismounting.
In order to solve above-mentioned technical problem; The utility model is realized through following technical scheme: a kind of shell and tube reactor water cap, comprise water cap plug, water cap end pipe, water cap wrapping wire, and it is characterized in that: water cap plug is grouped into by boss and external thread part; Water cap end pipe is made up of band female thread portion and boss; Water cap wrapping wire is made up of titanium ring, titanium wrapping wire and titanium plate, and in the water cap wrapping wire cover entry cap end pipe, water cap plug is fixed water cap wrapping wire with being threaded of water cap end pipe.
Described water cap plug top is drilled with aperture.
Adopt between described titanium ring, titanium wrapping wire and the titanium plate and be welded to connect.
Described titanium wrapping wire is a regular polygon, and the inner ring of titanium ring is the inscribed circle of titanium wrapping wire.
The external diameter of described titanium ring is between the internal diameter of the internal diameter of boss and band female thread portion.
Described boss is a regular polygon.
In the utility model, on the basis of original water cap, improve, the water cap is transformed into three parts by original two parts; The water cap wrapping wire that will have capstan nut transform water cap plug and water cap wrapping wire as, after the transformation, only needs water cap plug is back-outed from water cap end pipe during dismounting water cap; The water cap wrapping wire taking-up of cover entry cap end pipe is got final product, need not rotate water cap wrapping wire, therefore the titanium wrapping wire can not take place and scatter; The situation that the water cap damages has solved the difficult problem of water cap dismounting.Simultaneously, water cap plug and water cap wrapping wire are separated, make the inside of water cap wrapping wire be more prone to clean.
Description of drawings
Fig. 1 is the assembly structure sketch map of the utility model;
Fig. 2 is the structural representation of each parts of the utility model;
Fig. 3 is the vertical view of water cap plug;
Among the figure, 1 is water cap plug, and 2 is water cap end pipe, and 3 is water cap wrapping wire, and 4 is boss, and 5 is male thread portion, and 6 are the band female thread portion, and 7 is boss, and 8 is the titanium plate, and 9 is the titanium wrapping wire, and 10 is the titanium plate, the 11st, and aperture.
The specific embodiment
Below in conjunction with accompanying drawing and practical implementation instance the utility model is done further to set forth.
Can know that from Fig. 1, Fig. 2 the utility model shell and tube reactor water cap comprises water cap plug 1; Water cap end pipe 2, water cap wrapping wire 3, wherein water cap plug 1 is made up of with male thread portion 5 boss 4 of a regular polygon; Water cap end pipe 2 is made up of with boss 7 band female thread portion 6; Water cap wrapping wire 3 is made up of the titanium wrapping wire 9 and the titanium plate 10 of titanium ring 8, regular polygon, and wherein the inner ring of titanium ring 8 is inscribed circles of titanium wrapping wire 9, and the external diameter of titanium ring 8 is between the internal diameter of the internal diameter of boss 7 and band female thread portion 6.In the water cap wrapping wire 3 cover entry cap end pipes 2; Water cap wrapping wire 3 is fixing through water cap plug 1 then with being threaded of water cap end pipe 2; Titanium ring 8, titanium wrapping wire 9 and titanium plate 10 all are to adopt the mode of welding to be connected, and water cap end pipe 2 is fixed on the two ends of the tubulation of reactor through the mode of welding.Can know that from Fig. 3 water cap plug 1 top is drilled with aperture 11.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
