Description

A kind of cement rotary kiln

Technical field

The present invention relates to manufacture of cement manufacture field, specifically a kind of cement rotary kiln.

Background technique

Cement: powdery hydraulicity inorganic coagulation material.At slurry after adding water and stirring, can harden in air or in water Hardening, and can the materials such as sand, stone are cemented together securely.In the process of manufacture of cement, need using to revolution Kiln is processed, and cement rotary kiln belongs to building equipment class, is the one kind in limekiln.Rotary kiln can be divided by processing material difference Cement rotary kiln, chemical metallurgy rotary kiln and lime rotary kiln.Cement rotary kiln is clinker dry and wet production line Capital equipment.Cement kiln is mainly used for calcination of cement clinker, divides dry production cement kiln and wet production cement kiln two major classes.

Rotary kiln is typically mounted in the workshop of production cement, but since workshop dust is larger, a large amount of dust It easily adheres in the rotational structure of rotary kiln, since a large amount of adherency of dust are possible to cause the rotational structure of rotary kiln to rub It wipes power to increase, so that making the rotation of rotary kiln influences, in some instances it may even be possible to will appear the stuck phenomenon of rotary kiln.

Summary of the invention

For the problems of the prior art, the present invention provides a kind of cement rotary kilns.

The technical solution adopted by the present invention to solve the technical problems is: a kind of cement rotary kiln, including pedestal, revolution knot Structure, scrapes grey structure and anti-blockage structure at the structure that oils, and the top of the pedestal for playing the role of fixing and supporting is connected with For carrying out the revolving structure of rotation calcining to cement；The pedestal is connected with close to one end of the revolving structure and is used for The structure that oils described in upper oil lubrication is carried out to the revolving structure, the top of the pedestal is connected with for tying to the revolution Structure carries out the described of cleaning dust and scrapes grey structure；The pedestal is internally connected with for scraping grey structure to described to carry out shake anti- The anti-blockage structure of blocking.

Specifically, the revolving structure includes vertical plate, fixed column, roll shaft, pivoted housing, link block and kiln body, the vertical plate is set Have multiple, multiple vertical plates are both secured to the top of the pedestal, fixed between the vertical plate being set in parallel at two The fixed column of cylindrical structure is rotatably connected to the roll shaft in the outside of the fixed column, and the roll shaft is transversal Face is I-shaped structure, and the pivoted housing of arc, and the width of the pivoted housing are rotatably connected between two roll shafts Less than the width of the interior grooves of the roll shaft, the inside circular array of the pivoted housing is fixed with multiple link blocks, more The kiln body of a link block away from one end stationary annular of the pivoted housing.

Specifically, the structure that oils includes protective jacket, first rotating shaft, belt, the second shaft and oil groove, trapezium structure The perpendicular relationship of protective jacket is fixed on the top of the pedestal, and the inner rotation of the protective jacket is connected with described first turn Axis, the inner rotation of the pedestal is connected with second shaft, and the first rotating shaft is closed with second shaft in parallel System is equipped with the belt of kidney-shaped, and the first rotating shaft and described in the outside of the first rotating shaft and second shaft Second shaft is rotatablely connected with the belt, and the belt is equipped with multiple oil grooves, and the oil groove is in parallel four Side shape structure.

Specifically, described, to scrape grey structure include limit plate, scraper plate, fuel feed hole, rubber pad, filter screen and collecting tank, described There are two limit plate is set, two limit plates are fixed on the top of the pedestal in parallel relation, two limit plates it Between fix the scraper plate of rectangular parallelepiped structure, be fixed with described in trapezium structure in one end away from the pedestal of the scraper plate Rubber pad, and the rubber pad and the pivoted housing are rotatablely connected, the pedestal is equipped with the fuel feed hole of rectangular configuration, described The inside of pedestal is equipped with the collecting tank, and the inside of the pedestal is equipped with the filter screen, and the section of the filter screen is arc Shape structure.

Specifically, the anti-blockage structure includes mandril, bull stick, spring and rubber block, the mandril is fixed on described The outside of two shafts, and the mandril is arcuate structure away from one end of second shaft, the bar rotation is connected to institute The inside of pedestal is stated, the bull stick is fixed with the rubber block of rectangular parallelepiped structure, and institute away from one end of second shaft It states rubber block and the filter screen contradicts, the spring is fixed between the bull stick and the pedestal.

Beneficial effects of the present invention:

(1) a kind of cement rotary kiln of the present invention, by the rotation of revolving structure can be to revolving structure inside Cement carries out sufficient calcination process, and rotational structure is able to drive the structure that oils and carries out to revolving structure while rotation Oil work guarantees that revolving structure at work will not be due to a large amount of dusts so as to adequately just lubricate revolving structure Adherency causes frictional force to increase or even the stuck situation of revolving structure occur, has achieved the effect that make revolving structure more good berth, Grey structure is scraped by installing on the base, the dust being adhered on revolving structure can timely be cleared up, thus The structure that can guarantee to oil preferably works, additionally it is possible to the Excess lubricating oil for the structure injection that oils is collected, so as to The waste of lubricating oil is avoided, and oils structure while work, can constantly be hit by anti-blockage structure and scrape grey structure, It has dust at work so as to avoiding scraping grey structure to result in blockage, influences the work for scraping grey structure, that is, pass through the knot that oils The setting of structure can react on and scrape grey structure, enable to scrape grey structure and preferably work.

(2) a kind of cement rotary kiln of the present invention was rotated since pivoted housing and belt are mutually contradicted in pivoted housing Cheng Zhong, being able to drive belt also can be as rotation, one end of belt extends to inside the collecting tank equipped with lubricating oil, and in belt The oil groove for being equipped with multiple parallelograms can drive belt to rotate counterclockwise, belt that is, when pivoted housing rotates clockwise On oil groove the lubricating oil inside collecting tank can be contained, then reach contradicted with pivoted housing when, then will be in oil groove The outside of the lubricating oil injection pivoted housing in portion, so as to adequately be lubricated pivoted housing, so as to avoid due to a large amount of ashes Dirt is adhered to the damage that pivoted housing is caused on pivoted housing, by the setting of scraper plate, can carry out to the dust adhered to outside pivoted housing timely Scraping work guarantee the work of pivoted housing so as to clear up dust, and lubricating oil extra on pivoted housing can also be collected It is able to drive and turns so as to avoid the waste of lubricating oil, and through the second shaft while rotation into the inside of collecting tank Bar hits filter screen, so as to avoid the blocking of filter screen.
