Abstract

The utility model discloses a device for solving blanking of a rotary kiln, which comprises a rotary kiln barrel body. The device for solving blanking of the rotary kiln is characterized in that a feed end of the rotary kiln barrel body is provided with three-level blockings which are arranged from inside to outside in the rotary kiln with each higher than the previous, a first level blocking is a plane step type blocking, a second level blocking is a slope type blocking and a third level blocking is an upright steel plate block. By reducing the inner diameter of the feed end of the rotary kiln, a high slope or a blocking wall is formed so that materials do not perform counter motion after three blockings. Simultaneously, according to the device for solving blanking of rotary kiln, a feed inlet pipe enables dynamical state of the materials to change when the materials are fed and exhaust performs counter motion, accordingly, the blanking is greatly reduced and the problem of blanking dust originally polluting materials seriously and harming the health of workers is solved. Therefore, dusts produced by industries of using rotary industry kiln stoves such as industries of ceramsite, cement, chemical engineering and the like are reduced, the environment is protected, which are beneficial to the health of workers, and the factories can reduce the number of employees, reduce investment, lower the producing cost and decrease labor intensity of workers.

Description

A kind of device that solves rotary kiln blanking problem

Technical field

The utility model relates to reduce the device that the rotary kiln blanking forms.The industry that relates to is the industry that haydite sand, cement, chemical industry etc. use rotatable Industrial Stoves.Affiliated technology is the process technology equipment of these industries.

Background technology

The swinging Industrial Stoves are widely used in industries such as haydite sand, cement, chemical industry; In of the rotation of swinging kiln feed end material with the kiln body; A small amount of material is not gone ahead with the kiln body, retreats because of the Mechanics Cause of complicacy is reverse on the contrary, and is overflowed and formed blanking by charging aperture.In the industry of using kiln, though blanking has only 5-10%, the PR of these industries is bigger, and the absolute quantity of blanking is usually very considerable; And can also need the special messenger to clear up blanking simultaneously, and blanking is sent back to the place that feeds intake because of the blanking problem produces dust at this position; Therefore machinery, power consumption have been increased; Reduced production efficiency, therefore in plant produced, this has become the puzzlement and the difficult problem of aspects such as management, environmental protection.For many years, this difficult problem never finds better way.

Summary of the invention

In order to solve the blanking problem of rotary kiln, the utility model provides a kind of device that solves rotary kiln blanking problem.

The technical scheme of the utility model is achieved in that

The cylinder of rotary kiln feed end is provided with three grades to be stopped, three grades stop that one-level exceeds one-level by outside in the kiln, and being respectively the first order is that the plane step stops, the second level is that ramp type stops, the third level is that the vertical type steel plate stops.

Said plane step stops that the cylinder of rotary kiln feed end plays 970mm in kiln.

Ramp type stops that being positioned at the plane step stops on the termination cylinder of rotary kiln inwall.

The utility model device is through reducing the internal diameter of rotary kiln feed end; Form the high slope or the wall of blocking, make material after stopping for three times, no longer counter motion; Material dynamics state when the feed pipe of the utility model has also changed charging and tail gas reverse movement simultaneously; Can reduce blanking in a large number like this, make and pollute material originally seriously, the healthy blanking airborne dust problem of infringement workman has obtained solution.Thereby make the industry of use swinging Industrial Stoves such as haydite, cement, chemical industry reduce dust, protected environment, useful workman is healthy, also can reduce factory's recruitment, reduces investment, reduces production costs, and reduces labor strength.

Description of drawings

Accompanying drawing is the structural representation of the utility model;

Below in conjunction with accompanying drawing the content of the utility model is done further explain.

The specific embodiment

The cylindrical shell feed end inner lining structure of rotary kiln is generally the garden cylindricality of self-consistentency.The utility model forms slope of a step at feed end, and high platform mainly plays metope shelves wind and the effect of shelves material, and by strong diminuendo; And the material that stops also from more to less, and the effect on slope is that the less fines shelves of residue of iron plate circle and slope self institute shelves are lived, and lets their downslides be back to leading portion; Cylindrical shell with kiln rotates; Move forward, this version has increased the reverse movement resistance that material causes because of wind-force and solid accumulation, thereby has solved the blanking problem of rotary kiln.

The utility model is that the rotary kiln feed end stops liner for three grades; Three grades of utility model stop that one-level exceeds one-level by outside in the kiln, and the first order is the plane step; The second level is ramp type; The third level is that the vertical type steel plate stops, resistance shelves effect one-level is stronger than one-level, thereby has solved the problem of rotary kiln end blanking effectively.

The utility model structure by the plane step stop 1, ramp type stop 2 and vertical type stop that 3 form, as follows:

(1) the plane step stops 1, apart from feed end farthest, belongs to the top of this device.Rise at the kiln feed end and in kiln, to measure 970mm; Reserve and originally put start position; Throat thickness is 18mm on kiln tube inwall; The steel plate ring of wide 200mm above (because of heat-insulation layer, the flame retardant coating that highly contains the kiln body) puzzles heat-insulation layer, the flame retardant coating liner of kiln again, and the first that carries out this device then makes.Be to use T-17 standard refractory brick to build by laying bricks or stones to form the high 50--240mm that is during making, the stopping of long one-level plane step for 465mm.

(2) ramp type stops 2, and is placed in the middle with the feed end distance, belongs to the stage casing of this device.Earlier on the termination kiln tube inwall of this device first 1; Throat thickness is 18mm; The steel plate ring of wide 400mm above (because of heat-insulation layer, the flame retardant coating that highly contains the kiln body) puzzles heat-insulation layer, the flame retardant coating liner of kiln again, carries out the second portion of this device then and makes.Build formation by laying bricks or stones with heterotypic fire brick during making, the initiating terminal height stops high 320--520mm at 50--240mm, long ramp type resistance shelves for 465mm.

(3) vertical type stops 3, and its thick 18mm is tall and big in the steel plate ring of 420--960mm (because of heat-insulation layer, the flame retardant coating that highly contains the kiln body), and feed end cylindrical shell direct and kiln is welded.

This structure is applicable to rotary kiln, and size changes with the barrel diameter of rotary kiln.

The utility model at the charging port, get into kiln cylinder body 465mm place, the 948mm place, each steel plate ring of welding a thick 18mm links to each other with the kiln barrel, the width ecto-entad of steel plate horse stable reduces, but each size is identical with the height of peer.Then between this from inside to outside, inwardly build this structure by laying bricks or stones by wall with standard or heterotypic fire brick.Structure among way such as this paper 3 is formed said.At first play one and increase platform,, increase by one again and increase the slope, and form the discrepancy in elevation with the port steel plate ring up to rotary kiln charging port after 465mm.So just form two steps, three grades of barrier structures of a shelves wall.

This device is nonstandard design, and processing is to carry out at the scene that equipment is installed.Device size will determine according to the size of rotary kiln diameter, and can only on rotary kiln, use.
