AI Technical Summary
The corrosiveness and large particles of cement clinker lead to wear and shortened service life of screw conveyors. Existing technologies improve wear resistance by increasing the thickness of the screw blades, but this results in increased weight and cost.
A non-metallic wear-resistant material is installed on the outer edge of the spiral blade. The material is ceramic or plastic and fixed with glue or bolts to reduce welding and protect the blade from being damaged by hard objects.
It improves the wear resistance and operational stability of the screw conveyor, reduces weight gain, lowers costs, and facilitates assembly and maintenance.

[0026] As shown in Figures 1 to 5 A wear-resistant structure of a cement clinker screw conveyor, comprising,
[0027] The shaft body 1 is provided with a spiral blade 2 along the length direction of the outer peripheral wall, the front end of the shaft body 1 is a feeding end, and the blade 2 comprises an outer side wall 2a and an inner side wall 2b.
[0028] The cladding portion 3 is distributed along the outer peripheral edge 2c of the blade 2 and clads the outer peripheral edge 2c, and the cladding portion 3 is distributed along the length direction of the blade 2,
[0029] The cladding portion 3 is made of a non-metallic wear-resistant material.
[0030] In actual design, by arranging the cladding portion 3 on part of the blade 2, the outer peripheral edge 2c is effectively protected from being damaged by hard objects, and the transportation of the cement clinker is effectively ensured. At the same time, only the outer peripheral edge 2c is cladded, without increasing the weight, and the use stability of the screw shaft is improved. At the same time, the non-metallic material can be fixed by using glue and the like, reducing the welding process.
[0031] Specifically, the wear-resistant material is a ceramic material or a plastic material. The advantages of using these two materials are that the weight is lighter, and the outer peripheral edge 2c of the blade 2 can be better protected, thereby reducing the problem of the outer peripheral edge 2c being broken.
[0032] In the embodiments of the present application, the cladding portion 3 comprises an inner side layer 3b and an outer side layer 3a, and the width of the outer side layer 3a is smaller than the width of the inner side layer 3b. By the width difference, the use of more materials can be reduced, and the protection of the outer peripheral edge 2c can be achieved. At the same time, the outer side layer 3a is in contact with the material at a position of the outer peripheral edge 2c, so the width is smaller,
[0033] The inner side layer 3b is a conveying structure, so the inner side layer 3b is in contact with the inner side wall surface of the blade 2 at a position.
[0034] Specifically, the inner layer 3b and the outer layer 3a are an integral structure, and in actual design, the integral module is a segmented structure, and each segment is embedded into the blade 2.
[0035] In the embodiment of the utility model, the inner layer 3b and the outer layer 3a are provided with a clamping interval 3c, and the outer peripheral edge 2c is arranged in the clamping interval 3c.
[0036] Specifically, the clamping interval 3c and the outer peripheral edge 2c are fixed by glue or bolt 60.
[0037] In the embodiment of the utility model, the outer peripheral wall of the shaft body 1 is provided with a convex rib 4 distributed along the length thereof, and the convex rib 4 and the shaft body 1 are integrally formed. In actual production, the blade 2 is a segmented structure, and the modules are welded and fixed on the shaft body 1 segment by segment. The convex rib 4 can improve the strength of the shaft body 1, reduce the corrosion and collision deformation stress of the shaft body 1, and the convex rib 4 is preselected and then milled and formed.
[0038] In the embodiment of the utility model, the wall surface of the blade 2 towards the feeding end is provided with a wear-resistant block 6, and the wear-resistant block 6 is fixed by a bolt 60. In actual conveying process, the end of the spiral blade 2 generally directly extends into the material, so that the service life of the blade 2 can be improved by the arrangement of the wear-resistant block, and the replacement is facilitated.
[0039] Specifically, the cladding part 3 is provided with a concave line 5 distributed along the width thereof, so as to reduce the thermal expansion damage caused by heating during fitting or use, and improve the service life.
[0040] The cladding part is located at the position of the blade edge in a wedge shape.
[0041] The above only describes the preferred embodiments of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation or direct / indirect application in other related technical fields under the utility model concept of the utility model is included in the patent protection range of the utility model.
