Description

Technical Field

[0001] The utility model relates to the field of cement grinding and powder selection technology experimental equipment, in particular to an angle-adjustable baffle and a cold mold V-shaped powder selection machine. Background Art

[0002] The V-type powder classifier is an important sorting equipment in large-scale cement production lines. The cement material is broken up and sorted on the baffles, so the arrangement of the baffles affects the sorting effect of the V-type powder classifier. In the prior art, the baffles in the V-type powder classifier are arranged in a stepped manner. However, in the actual production process, complex material composition and unstable working conditions will cause the V-type sorting effect of the fixed baffle arrangement to be poor. Therefore, it is necessary to design a baffle angle with adjustable angle, and change the wind direction and wind speed between the baffles by adjusting the angle of the guide plate, so that the V-type powder classifier can always achieve better working performance.

[0003] As an experimental model of the actual V-type powder classifier, the cold mold V-type powder classifier is several times smaller than the actual one but has a similar sorting effect to the actual V-type powder classifier. Therefore, the feasibility of the modification and adjustment can be verified by the cold mold V-type powder classifier before the actual V-type powder classifier is modified. Compared with the large-scale V-type baffle adjustment device (patent number 200920270089.8), the cold mold V-type powder classifier adjustment mechanism has a simple structure, and the baffle can be accurately adjusted with a measurable angle. It can be used for powder selection experiments with baffles at multiple angles, and can also provide experimental methods and basis for the modification of large-scale actual V-type powder classifiers.

[0038] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the utility model. These all fall within the scope of protection of the utility model.

[0039] like Figure 1 As shown, it is a cross-sectional view of an angle-adjustable baffle in an embodiment of the utility model, which can be seen to include a baffle body 100, a fixing mechanism 200, an adjusting mechanism 300 and a reference mechanism 400. Among them, the fixing mechanism 200 is fixed to the baffle body 100, and can also be used to fix it to a V-type powder classifier. The adjusting mechanism 300 is located on one side of the fixing mechanism 200, and is used to adjust the angle of the fixing mechanism 200, thereby driving the position of the baffle body 100, so as to achieve the purpose of changing the angle of the baffle body 100. The reference mechanism 400 is connected to the adjusting mechanism 300 to provide an angle reference for the adjusting mechanism 300.

[0040] For details, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixing mechanism 200 includes a tubular shaft 201, a slot is provided in the middle of the shaft 201, and the rectangular baffle body 100 is inserted between the slots and fixed by fixing parts (such as bolts and nuts). A nut 202 is provided at each end of the shaft 201. Three limiting grooves 203 are also provided at one end of the shaft 201, and the limiting grooves 203 surround the outer wall of the shaft 201 to form a circle.

[0041] The adjustment mechanism 300 includes an angle adjuster, which is composed of an integrally formed gear plate 301 and a rotating handle 302. Figure 4 The gear plate 301 is an annular structure, with gear teeth on its outer periphery and three protruding clips 303 on its inner periphery that match the limit grooves 203 . The rotating handle 302 is plate-shaped, with one end being blunt and the other end connected to one side of the gear plate 301 .

[0042] The reference mechanism 400 includes an angle reference device, which includes a fixed surface 401 and a scale surface 402. The fixed surface 401 is an annular structure, and a plurality of fixing holes 403 are provided on its outer peripheral edge, and its inner diameter is equal to the outer diameter of the shaft 201; the scale surface 402 is a conical annular structure, which is fixed and protrudes from one side of the fixed surface 401, and its inner circumference is gear-shaped, and each gear tooth corresponds to an angle scale.

[0043] Based on the same utility model concept, another embodiment of the utility model further provides a cold mold V-type powder classifier based on an angle-adjustable baffle.

[0044] The cold mold V-type powder classifier includes a V-type powder classifier body 5, the structure of which is consistent with the powder classifier in the prior art, but its internal baffles use several angle-adjustable baffles of the utility model, and the angle-adjustable baffles span the internal cross-section of the powder classifier.

[0045] Specifically, the shaft 201 is connected to the baffle body 100 and passes through the cold mold V-type powder classifier. One end is fixed to the V-selection wall by a fixing nut and a gasket, and the other end is connected to the angle reference, the angle adjuster and the fixing nut.

[0046] The fixing surface of the angle reference device is close to the baffle body, and is sleeved on the shaft rod. The fixing surface is fixed to the V-selected wall surface by bolts, so that the angle reference device is fixed to the V-selected wall surface.

[0047] The end of the shaft on which the angle reference device is installed has a limit groove 203 for fixing the angle adjuster. Specifically, the gear plate 301 of the angle adjuster is sleeved on the shaft 201, and the protruding clip on the inner ring is inserted into the limit groove 203, so as to fix the angle adjuster and the shaft 201. The gear on the outer ring of the gear plate 301 is adapted to fit with the gear teeth on the inner circumference of the angle reference device. It can be seen that the angle reference device can radially fix the angle adjuster. The inner concave part in the middle has a gear, and the gear corresponds to the angle scale, which can accurately adjust the shaft at multiple angles.

[0048] The end is fixed by a fixing nut to prevent axial displacement of the shaft.

[0049] The adjustment process of the baffle adjustment device inside the cold mold V-type powder classifier of this embodiment is as follows: loosen the fixing nuts at both ends of the shaft, pull the angle adjuster out of the angle reference device along the axial direction of the shaft, use the rotating handle to rotate the shaft to the required angle, and then push the angle reference device along the axial direction so that the gear plate fits with the angle reference device. Finally, tighten the fixing nuts at both ends to complete the adjustment of the baffle angle.

[0050] In this embodiment, a cold mold V-type powder separator is selected because its size is several times smaller than the actual size and has a separation effect similar to that of the actual V-separator. In other embodiments, the angle-adjustable baffle is not limited to be used in the actual V-separator.

[0051] The above describes the specific embodiments of the utility model. It should be understood that the utility model is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which does not affect the essence of the utility model. The above preferred features can be used in any combination without conflicting with each other.
