Description
Technical field
The utility model relates to a kind of coal injection pipe external member.
Technical background
Coal injection pipe is the key equipment of burning clinker of cement, due to the work of coal injection pipe long term high temperature and each position is heated inequality, especially head end body easily deforms, therefore, often need to dismantle coal injection pipe, the body more renewed is installed, but, traditional coal injection pipe body and burner body are threaded connection, when needing to remove coal injection pipe body, need first whole coal injection pipe handling to be backed out one by one by bolt after on one side, need again bolt to tighten one by one after the coal injection pipe body more renewed, installing/dismounting is extremely required great effort again.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of coal injection pipe external member, and installation and removal are more prone to.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of coal injection pipe external member, comprise coal injection pipe body, described coal injection pipe body is connected with tube connector, described tube connector is connected by bolt with burner body, one end outer wall that described coal injection pipe body is connected with tube connector is provided with projection, one end inwall that described tube connector is connected with coal injection pipe body is provided with the groove coordinated with projection, the other end of described tube connector is provided with inside radius and is greater than the shoulder hole of projection to the vertical range in coal injection pipe body axle center, on described coal injection pipe body outer wall, circumference is distributed with several locating holes, described tube connector is provided with the through hole coordinating with locating hole and align, described tube connector is provided with the alignment pin penetrating through hole and locating hole successively, block is provided with in described shoulder hole, described block and projection against time, locating hole aligns with through hole.
Preferably, described tube connector is provided with positioning seat, the cylinder of described alignment pin is provided with at least one strip projected parts, be provided with the jack of grafting alignment pin cylinder in described positioning seat and be arranged at the locating slot that jack inwall coordinates with strip projected parts, be provided with spring between described alignment pin and tube connector outer wall, described spring housing is connected to positioning seat periphery.
Preferably, one end that described tube connector is connected with burner body is provided with the terminal pad extended radially outward, and described terminal pad circumference is evenly equipped with several connecting holes, and described tube connector is by penetrating bolt and burner body is connected in connecting hole.
The beneficial effects of the utility model are:
The utility model by arranging tube connector between coal injection pipe body and burner body, and coal injection pipe body by projection and the rotary shifted laggard conduct of groove to spacing, circumference is carried out again spacing by alignment pin, when needing installation and removal coal injection pipe, only need the connection of coal injection pipe body and tube connector and be separated, and tube connector can be connected by bolt with burner body always, need frequent work of twisting bolt when eliminating the installation and removal of coal injection pipe body, greatly simplify the installation and removal process of coal injection pipe body and tube connector.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation at a kind of visual angle of tube connector in the utility model;
Fig. 3 is the structural representation at the another kind of visual angle of tube connector in the utility model;
Fig. 4 is the partial enlarged drawing of a-quadrant in Fig. 1;
Fig. 5 is the top view of positioning seat in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1 to Figure 3, the utility model comprises coal injection pipe body 1, described coal injection pipe body is connected with tube connector 2, described tube connector is connected by bolt with burner body 3, one end outer wall that described coal injection pipe body is connected with tube connector is provided with projection 101, one end inwall that described tube connector is connected with coal injection pipe body is provided with the groove 201 coordinated with projection, the other end of described tube connector is provided with inside radius and is greater than the shoulder hole 202 of projection to the vertical range in coal injection pipe body axle center, on described coal injection pipe body outer wall, circumference is distributed with several locating holes 102, described tube connector is provided with the through hole 203 coordinating with locating hole and align, described tube connector is provided with the alignment pin 4 penetrating through hole and locating hole successively, block 2021 is provided with in described shoulder hole, described block and projection against time, locating hole aligns with through hole.One end that described tube connector 2 is connected with burner body is provided with the terminal pad 204 extended radially outward, and described terminal pad circumference is evenly equipped with several connecting holes, and described tube connector is by penetrating bolt and burner body is connected in connecting hole.
As shown in Figure 4 and Figure 5, described tube connector 2 is provided with positioning seat 5, the cylinder of described alignment pin is provided with at least one strip projected parts 401, be provided with the jack 501 of grafting alignment pin cylinder in described positioning seat and be arranged at the locating slot 502 that jack inwall coordinates with strip projected parts, spring 6 is provided with between described alignment pin 4 and tube connector 2 outer wall, it is peripheral that described spring housing is connected to positioning seat 5, location is pulled upwardly rear rotation can make strip projected parts and locating slot misplace, thus make alignment pin keep unlocking the spacing state of coal injection pipe body circumference, multiple alignment pin can be untied one by one by single, and do not need many people to hold.
Installation and removal process of the present utility model is:
During installation, first, rotate to an angle after alignment pin pull-up, strip projected parts and locating slot are misplaced, thus make alignment pin keep unlocking the spacing state of coal injection pipe body circumference, after projection alignment indentation, coal injection pipe body is pushed in tube connector, until the end of coal injection pipe body is against the head end of burner body, now, projection is positioned at shoulder hole, inside radius due to shoulder hole is greater than the vertical range of projection to coal injection pipe body axle center, therefore, coal injection pipe body can rotate and projection and groove are misplaced, thus by coal injection pipe body axial location, coal injection pipe rotates to projection and block against rear, locating hole aligns with through hole, finally, rotate alignment pin, after strip projected parts is alignd with location, decontrol alignment pin, can by coal injection pipe body circumference location, complete the installation of coal injection pipe body.
During dismounting, with above-mentioned, reverse operating was installed.
Be described with regard to the utility model preferred embodiment above, but can not be interpreted as it is restriction to claim.The utility model is not only confined to above embodiment, its concrete structure allows to change, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all belong to the scope that the utility model claims define.
