Technical field

The present invention relates to detection device technical fields, and in particular to a kind of rotary type anticorrosion detection device.

Background technique

The installation of the temperature measuring instrument of ore pulp in aluminium oxide bayer process production process, the autoclave of high pressure digestion Process refers to the design method and installation method of France Bi Sinie.I.e. as shown in Figure 1, by by pulp temp measuring instrument 02 is directly installed on the shell of autoclave 01, and temperature measuring set 02 protrudes into the shell of autoclave 01.

In production process, since the ore pulp in autoclave contains alkali, temperature measuring instrument can be produced under high temperature and high pressure condition Raw biggish abrasion.The shell that long-time service will lead to temperature measuring instrument is worn out, passes through so as to cause the ore pulp in autoclave Temperature measuring instrument, and then the generation for leading to production accident is revealed from the shell of autoclave.

Summary of the invention

In view of the deficiencies of the prior art, the present invention discloses a kind of rotary type anticorrosion detection device, is able to solve temperature survey Measure the worn out problem of shell caused by instrument is used for a long time.

In order to achieve the above object, the present invention is achieved by the following technical programs:

A kind of rotary type anticorrosion detection device, including autoclave outer housing and autoclave inner housing, in the autoclave It is provided with protection sleeve pipe at the top of outer housing, the protection sleeve pipe is from the autoclave outer housing to the autoclave inner housing Internal stretch is provided with temperature instrument in the protection sleeve pipe, the autoclave outer housing is provided with mounting groove, institute Top and the mounting groove rotation connection for stating protection sleeve pipe, are provided with guide groove, the guiding in the autoclave inner housing Slot extends along the rotation direction of the protection sleeve pipe, throwing of the mounting groove on the direction perpendicular to the autoclave inner housing Shadow is fallen in the guide groove, and the protection sleeve pipe passes through the guide groove, the temperature instrument and the protection sleeve pipe Coaxial arrangement.

Preferred technical solution is provided with mounting hole in the side wall of the mounting groove, sets in the side wall of the protection sleeve pipe It is equipped with the shaft with mounting hole coaxial arrangement, the shaft and mounting hole rotation connection, the protection pipe sleeve is along institute State circumferentially rotating for mounting hole.

Further preferred technical solution is provided with the first arcwall face in the mounting groove, and first arcwall face is along institute The circumferentially extending for stating mounting hole is provided with the second arcwall face on the top of the protection sleeve pipe, and first arcwall face is described in The sliding of second arcwall face.

Further preferred technical solution is provided with the first positioning surface, first positioning in one end of the guide groove Face is obliquely installed, and the other end of the guide groove is provided with the second positioning surface, second positioning surface is obliquely installed.

Further preferred technical solution is provided with third positioning surface, the third positioning in one end of the guide groove Face is obliquely installed, and the other end of the guide groove is provided with the 4th positioning surface, the 4th positioning surface is vertically arranged.

Further preferred technical solution is provided with the first guide face in the side of the protection sleeve pipe, and described first leads A part that the cross-sectional shape of stream interface is provided in round is provided with the second refluence face, institute in the other side of the protection sleeve pipe The cross-sectional shape for stating the second guide face is set as a part of ellipse, first guide face and the second guide face light Slip.

Further preferred technical solution, the autoclave outer housing and the autoclave inner housing separate setting, in institute It states and forms protection chamber between autoclave outer housing and the autoclave inner housing.

The present invention discloses a kind of rotary type anticorrosion detection device, has the advantage that

Temperature instrument is protected by the protection sleeve pipe of setting, can effectively avoid containing under high temperature and high pressure condition Contact of the alkali ore pulp with temperature instrument, to avoid the worn out caused ore pulp of the shell of temperature measuring instrument from autoclave Shell leakage, and then the security performance of autoclave and temperature instrument is improved, be conducive to stablizing for production process and carry out.

The protection sleeve pipe of setting can follow the flow direction of ore pulp to rotate in the course of work, can effectively reduce protective case The active force from ore pulp that the radial direction of pipe is subject to, so that ore pulp caused by avoiding protection sleeve pipe from being broken is let out from the shell of autoclave Dew, and then improve the service life of protection sleeve pipe.

The rotation direction and rotational angle of protection sleeve pipe are limited by the guide groove of setting, can effectively avoid protecting Protecting pipe rotates the direction of excessive angle and mistake under the action of ore pulp, to avoid protection sleeve pipe and temperature instrument The random motion in autoclave, and then improve the stabilization of temperature instrument and the precision of testing result.

By the way that mutually matched first arcwall face and the second arcwall face is arranged, the rotation of protection sleeve pipe can be drawn It leads, to improve the smooth degree of protection sleeve pipe rotation process, furthermore it is possible to after shaft stress or aging fracture, to protection sleeve pipe Rotation be supported, to guarantee the normal rotation of protection sleeve pipe.

The first positioning surface and the second positioning surface being arranged being capable of maximum rotation angles at the both ends of guide groove to protection sleeve pipe Degree is defined, while the first positioning surface and the second positioning surface are obliquely installed, can in the first positioning surface and the second positioning surface and When the outer wall contact of protection sleeve pipe, sufficiently large contact area is provided, to reduce the outer wall of protection sleeve pipe in contact position Pressure, to improve the service life of protection sleeve pipe.

Water conservancy diversion is carried out to ore pulp by the first guide face of setting, enables to ore pulp along the first water conservancy diversion towards protection sleeve pipe Two sides flowing, to reduce direct impact of the ore pulp to the first guide face, by the second guide face of setting to ore pulp carry out into The guidance of one step enables to the ore pulp of the two sides of protection sleeve pipe to be adjacent to the two sides flowing of protection sleeve pipe, to improve protection sleeve pipe With the time of contact of ore pulp, and then improve temperature instrument detection time and detection effect.
