Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a wear-resistant plate structure for an air outlet on an upper casing of a quicklime crushing and air separation integrated machine. Background Art

[0002] The integrated fan is the key structure of the quicklime gas separation machine. The throat of the traditional fan end casing is the airflow dividing point, which is greatly impacted by the material and suffers severe wear, repeatedly causing wear and tear shutdown accidents. Figure 2 In the previous design, a liner was installed in the casing. Although the liner can prevent the material from wearing the casing, the liner will also wear at the throat, and eventually the casing will be worn to the point of air leakage, resulting in a short service life. In addition, the connection between the liner plates is located at the throat, which makes a lot of noise. In this design, the throat is designed as an integral wear-resistant plate casting structure, which reduces airflow disturbances, extends the service life of this part by more than 5 times, reduces the fan noise by more than 20 decibels, and thickens the wear-resistant plate at the throat to increase service life, solve the problem of dust overflow caused by wear, reduce downtime, and greatly increase the reliability of the whole machine. It is an innovative design. Utility Model Content

[0003] The purpose of the utility model is to provide a wear-resistant plate structure for the air outlet of the upper casing of a quicklime crushing and air separation integrated machine, so as to solve the problems of easy wear and high noise at the throat of the casing proposed in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the wear-resistant plate structure of the air outlet of the quicklime crushing and gas separation integrated machine includes a plurality of lining plates fixed on the inner wall of the casing, and the lining plates are connected to each other. The two lining plates located at the throat of the casing are throat lining plate 1 and throat lining plate 2 respectively. The upper part of throat lining plate 1 is fixed to the inner wall surface of the air outlet of the casing. The bottom of throat lining plate 1 is provided with an integrally formed protrusion, and the inner wall surface of the protrusion is a smooth arc surface, and the connecting port formed between the protrusion and throat lining plate 2 deviates from the throat of the casing.

[0005] Preferably, the throat of the casing is planar and fits in place with the protrusion, and two ends of the plane form two obtuse angles with the air outlet of the casing and the volute respectively.

[0006] Preferably, the connection between the protrusion and the throat lining plate 2 is greater than 5 cm away from the throat of the casing.

[0007] Preferably, a plurality of reinforcing ribs are provided on an inner wall surface of the throat lining plate.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The utility model discloses a wear-resistant plate structure for the air outlet of the upper casing of the quicklime crushing and air separation integrated machine. By thickening the bottom of the throat lining to form a bulge, the wear resistance of the lining is increased, thereby indirectly improving the service life of the casing. At the same time, the throat lining connection port deviates from the throat of the casing, thereby reducing noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] See also Figure 2 In order to improve the throat position diagram before, the bottom of the throat liner three 5 is the throat scouring point 7, which is subject to large impact and wear. When this place is completely worn, the casing will also be easily worn, resulting in leakage, and the connection between the throat liner four 6 and the throat liner three 5 is located at the scouring point 7, which generates loud noise.

[0015] See Figure 3 The wear-resistant plate structure of the air outlet of the quicklime crushing and air separation integrated machine includes multiple lining plates fixed to the inner wall of the casing. The lining plates are connected to each other. The two lining plates located at the throat of the casing are throat lining plate 1 and throat lining plate 2. The upper part of throat lining plate 1 is fixed to the inner wall of the casing air outlet. The bottom of throat lining plate 1 is provided with an integrally formed protrusion 4. The inner wall surface of protrusion 4 is smooth and cambered, and the connection port 3 formed between protrusion 4 and throat lining plate 2 deviates from the throat of the casing. The thickness of protrusion 4 is thicker than that of the previous lining plate, so its wear resistance is also stronger. The connection port 3 between the two throat lining plates deviates from the throat of the casing, and the distance between the connection port 3 and the throat of the casing is greater than 5 cm, which means that it deviates from the airflow demarcation point, which can effectively reduce noise.

[0016] Furthermore, the throat of the casing is flat and fits in with the protrusion 4, and the two ends of the plane form two obtuse angles with the casing air outlet and the volute respectively. Multiple reinforcing ribs are set on the inner wall of the throat lining 1 to improve the structural strength.
