Description

Technical Field

[0001] The utility model belongs to the technical field of material blanking application in a tail smoke chamber of a cement kiln, and particularly relates to a material blanking plate which is resistant to material blanking impact. Background Art

[0002] The kiln tail discharge plate is installed at the smoke chamber discharge port at the tail of the rotary kiln body to guide the discharge of calcined materials.

[0003] At present, after the traditional kiln tail discharge plate is installed, it is subjected to the impact and wear of the calcined material discharged from the rear kiln mouth, which causes the casting material to be damaged. There is a phenomenon that large pieces of casting material fall off (in severe cases, the kiln tail smoke chamber discharge tongue plate assembly is dragged away by the rear kiln mouth). This requires regular maintenance and frequent replacement, which increases economic costs. Frequent shutdowns for maintenance also reduce production efficiency. At the same time, there is also leakage at the kiln tail, which leads to production safety and environmental protection problems.

[0004] After searching: Application No. / Patent No. 201320287608.8, a dry-process cement kiln tail smoke chamber discharge tongue assembly with a long service life is disclosed, including several discharge tongue plate units, the structure of each discharge tongue plate unit is as follows: including a discharge tongue plate with a rear end portion bent downward, the rear end edge of the discharge tongue plate is fixed to the connecting end plate, two reinforcing ribs are arranged between the connecting end plate and the lower surface of the middle and rear part of the discharge tongue plate, the front end of the discharge tongue plate is fixed to a casting baffle located above the discharge tongue plate, two reinforcing ribs with holes are arranged between the casting baffle and the upper surface of the middle and front part of the discharge tongue plate, "V"-shaped anchors are spot welded and fixed in the holes, and "V"-shaped anchors are welded and fixed on the upper surface of the discharge tongue plate; the connecting end plate of each discharge tongue plate unit is fastened to the lower end flange of the discharge slope of the tail smoke chamber by bolts, all the discharge tongue plate units are arranged in a circular arc, and then castable is applied on the above structure to form a castable layer.

[0005] After analysis, the problem is: the reinforcing ribs of the blanking tongue assembly are symmetrically arranged on the blanking tongue, and during the blanking process, the material will impact the blanking tongue. In this way, the reinforcing ribs cannot directly bear the pressure of the blanking tongue, and the blanking tongue will be deformed after long-term use.

[0006] Therefore, based on the above problems, the present invention provides a blanking plate that is resistant to blanking impact. Utility Model Content

[0022] Example 1

[0023] like Figure 1 and Figure 2 The rotary kiln tail guard plate shown in the figure includes an arc-shaped fixing portion 100, a sloped discharge portion 101, a set of inclined support ribs 102, two sets of fixing screw holes 103, a horizontal support rib 104 and a horizontal limit clamping plate 105;

[0024] One end surface of the sloped blanking portion 101 is connected to one side wall of the arc-shaped fixing portion 100.

[0025] The two sets of fixing screw holes 103 are evenly distributed in the other end surface of the arc-shaped fixing portion 100.

[0026] The horizontal limiting clamping plate 105 is arranged on one end surface of the sloped blanking portion 101.

[0027] The horizontal supporting rib 104 is arranged on the end face of the symmetrical center line of the sloped blanking portion 101, and one end is connected to the horizontal limiting clamping plate 105.

[0028] A set of oblique support ribs 102 are provided on one side of the sloped blanking portion 101, and the two ends are connected to the horizontal support ribs 104 and the horizontal limit clamping plate 105 respectively;

[0029] A group of oblique supporting ribs 102 are V-shaped and arranged on one side of the sloped blanking portion 101 .

[0030] The working principle is: when the material impacts the sloped blanking part 101, a group of inclined supporting ribs 102 and transverse supporting ribs 104 directly support the sloped blanking part 101 to improve the impact resistance of the sloped blanking part 101.

[0031] In addition, preferably, a group of inclined support ribs 102 and transverse support ribs 104 are respectively set to slope structures, and the height dimension gradually decreases from the connection surface with the transverse limit clamp 105 to the other end face. Such a design structure matches the slope angle of the sloped blanking part 101, saving raw materials while not affecting its load-bearing capacity.

[0032] Example 2

[0033] On the basis of the first embodiment, the blanking plate resistant to blanking impact further includes a horizontal limiting clamping plate screw groove 1051 provided in the end surface of one end of the horizontal limiting clamping plate 105, and a horizontal L-shaped sloped blanking protective layer 106 provided on the surface of the sloped blanking portion 101, and a countersunk screw hole 1061 provided in the end surface of one end of the horizontal L-shaped sloped blanking protective layer 106, and a bolt 107 for fixing the sloped blanking portion 101 and the horizontal L-shaped sloped blanking protective layer 106 through the countersunk screw hole 1061 and the horizontal limiting clamping plate screw groove 1051;

[0034] The sloped blanking portion 101 and the horizontal L-shaped sloped blanking protective layer 106 respectively include, but are not limited to, ceramic alloy stainless steel, and the bolts 107 are high-temperature resistant bolts.

[0035] The working principle is: the horizontal L-shaped sloped material protection layer 106 is located on the surface of the sloped material portion 101. When the material is discharged and impacted, the material contacts the horizontal L-shaped sloped material protection layer 106, thereby covering and protecting the sloped material portion 101 and effectively extending the durability of the overall structure.

[0036] In addition, preferably, the width and slope structure dimensions of the sloped blanking portion 101 and the horizontal L-shaped sloped blanking protective layer 106 are the same;

[0037] Among them, one side of the horizontal L-shaped sloped material cutting protection layer 106 is tightly attached to the surface of the sloped material cutting part 101. At the same time, the horizontal L-shaped sloped material cutting protection layer 106 fully covers the surface of the sloped material cutting part 101 after assembly, realizing all-round and dead-angle-free protection of the sloped material cutting part 101 against material impact.

[0038] In addition, the thickness of the arc-shaped fixing portion 100 is preferably greater than the thickness of the sloped blanking portion 101, so that the arc-shaped fixing portion 100 is used to be firmly and stably fixed to the fixing components of the cement kiln tail smoke chamber.

[0039] The blanking plate of this structure that is resistant to blanking impact refers to Example 1 and Example 2. It has two design structures and forms two assembly working modes, which can adapt to different design, assembly and use requirements.
