Technical Field

[0001] The utility model relates to the technical field of pulverizing devices, in particular to a wear-resistant raw material pulverizer for the inner lining of thermal energy equipment. Background Art

[0002] In the production of refractory materials, the main steps are to crush the raw materials and grind them into powder, then mix the various raw materials according to different proportions, and stir the mixed raw materials evenly through mixing equipment, and finally package them into bagged products. Before the various raw materials are mixed, the crushed raw materials are ground into powder, and a ball mill is needed to make the raw materials more fully crushed, thereby ensuring the quality of the refractory materials.

[0003] During the operation of the existing ball mill, the sizes of the crushed particles of the materials are different. The crushed particle size of some materials is small and meets the crushing requirements in advance, while the crushed particle size of the remaining materials is large and it takes a long time to meet the crushing requirements. In order to make the vast majority of material particles meet the crushing requirements, it is necessary to ensure that the ball mill runs for a sufficiently long time. During this period of time, the particles that meet the crushing requirements in advance cannot be separated and discharged, which affects the crushing of the remaining particles by the ball mill, resulting in a low crushing efficiency of the ball mill.

[0004] Therefore, it is necessary to propose a wear-resistant raw material crusher for the lining of thermal energy equipment to improve the crushing efficiency of the ball mill. Utility Model Content

[0010] Furthermore, a limit rod is provided on the inner wall of the conveying tank. The limit rod is located at one end of the conveying tank where the discharge port is located. The limit rod contacts one end of the conveying tank and is rod-shaped.

[0011] Furthermore, the guide plate is fixedly connected to the inner wall of the conveying tank.

DETAILED DESCRIPTION

[0021] In order to make the technical means, technical features, utility model objectives and technical effects achieved by the utility model easy to understand, the utility model is further explained below with reference to specific illustrations.

[0022] Embodiment 1:

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a wear-resistant raw material crusher for the lining of thermal energy equipment, including a base 1, the base 1 is provided with a power device 2 and a crushing tank 3, a grinding piece 4 is arranged in the crushing tank 3, the inner wall of the crushing tank 3 is provided with filter holes 5, the filter holes 5 are evenly distributed on the crushing tank 3 along the axial direction and the circumferential direction, the filter holes 5 are circular, a conveying tank 6 is sleeved on the outer side of the crushing tank 3, the inner wall of the conveying tank 6 is processed with a guide plate 8 by a machine tool, the conveying tank 6 is fixedly connected to the crushing tank 3, the conveying tank 6 is rotatably connected to the base 1 through a bearing, and the power device 2 and the crushing tank 3 are provided. The device 2 drives the conveying tank 6 to rotate, and a discharge port 7 is opened at one end of the conveying tank 6, and the guide plate 8 is retracted toward the discharge port 7. Preferably, the power device 2 includes a motor 14, a reducer 15, a driving gear 16 and a driven gear 17. The motor 14 is fixed to the base 1 with screws, and the motor 14 is connected to the reducer 15 by a key. The driving gear 16 is keyed to the output shaft of the reducer 15, and the driven gear 17 is meshed with the driving gear 16 for transmission. The driven gear 17 is an outer ring gear or an annular gear, and is fixed to the side wall of the conveying tank 6 with screws.

[0024] Preferably, a feed channel 9 is opened on the top of the crushing tank 3, and a feed port 10 is provided at a position on the conveying tank 6 corresponding to the feed channel 9. The feed port 10 and the feed channel 9 are circular, and the material to be crushed can be put into the crushing tank 3 and the conveying tank 6 through the feed port 10.

[0025] Preferably, the conveying tank 6 is connected with an end cover 11 by means of screws. The end cover 11 is located at the opposite end of the conveying tank 6 where the discharge port 7 is located. The end cover 11 is also fixedly connected to the crushing tank 3 by means of screws.

[0026] Preferably, a limit rod 12 is provided on the inner wall of the conveying tank 6. The limit rod 12 is rod-shaped and has a circular cross-section. The limit rod 12 is located at one end of the conveying tank 6 where the discharge port 7 is located. The limit rod 12 contacts one end of the conveying tank 6. Preferably, the guide plate 8 is welded to the inner wall of the conveying tank 6. When the conveying tank 6 and the crushing tank 3 rotate at high speed, if the conveying tank 6 and the crushing tank 3 are not fixed, the crushing tank 3 may rotate relative to the conveying tank 6. The crushing tank 3 can be fixed to the end cover 11 by screws, and the end cover 11 is fixed to the conveying tank 6 by screws. The limit rod 12 It can support one end of the crushing tank 3, and the other end of the crushing tank 3 is fixed by the end cover 11. The limiting rod 12 and the end cover 11 can prevent the crushing tank 3 from axial movement. The guide plate 8 can support the crushing tank 3 in the radial direction, so that the crushing tank 3 is always coaxial with the conveying tank 6. The screws fix the end cover 11 and the conveying tank 6, and the screws fix the end cover 11 and the crushing tank. Therefore, the crushing tank 3 and the conveying tank 6 can be fixed in the circumferential direction to prevent the crushing tank 3 and the conveying tank 6 from relative rotation. The relative fixation of the conveying tank 6 and the crushing tank 3 can be achieved through the limiting rod 12, the guide plate 8 and the end cover 11.

[0027] Preferably, the grinding member 4 is spherical and made of a metal material with a high density such as steel. The high density results in a large weight, which can ensure the grinding effect.

[0028] Preferably, the end cover 11 is fixedly connected to the crushing tank 3 by screws.

[0029] Preferably, a filter screen 13 is provided in the filter hole 5, and the filtering accuracy of the filter screen 13 is higher than the filtering accuracy of the filter hole 5. Since the crushing tank 3 is generally made of metal, if the aperture of the filter hole 5 is too small, it is difficult to process. The filter screen 13 is installed in the filter hole 5, and the filter screen 13 with appropriate filtering accuracy can be selected according to the crushing requirements. When some fine particles that meet the crushing standards enter the filter hole 5, they can pass through the filter screen 13 and be discharged, while the material particles that do not meet the standards cannot pass through the filter screen 13 after entering the filter hole 5 and remain in the filter hole 5. As the rotating filter hole 5 rotates to the height of the crushing tank 3, the material will fall from the filter hole 5 back into the crushing tank 3, and continue to be ground and crushed by the grinding piece 4.

[0030] Preferably, the filter screen 13 is made of a relatively hard metal or metal alloy. Preferably, the filter holes 5 are evenly distributed on the side wall of the crushing tank 3. Preferably, the crushing tank 3 and the conveying tank 6 are both cylindrical in shape.

[0031] The material in the crushing tank 3 is ground by the grinding element 4 under the action of its own gravity and the centrifugal force in the tank, and the material that meets the standards in advance enters the filter hole 5 and then passes through the filter screen 13 and is discharged into the conveying tank 6. As the guide plate 8 is gathered toward the discharge port 7, the guide plate 8 in the conveying tank 6 will guide the crushed particles that meet the requirements to the discharge port 7 and discharge them out of the conveying tank 6, while the particles that do not meet the standards will be blocked by the filter screen 13. As the crushing tank 3 rotates, the particles will return to the tank body of the crushing tank 3 from the filter hole 5 again, and finally be crushed by the grinding element 4, so as to achieve the filtering and separation of particles that meet the requirements and particles that do not meet the requirements.

[0032] Since the material is always at the bottom of the crushing tank 3 during grinding, when it enters the conveying tank 6 through the filtering hole 5, it is also located at the bottom of the conveying tank 6, and with the rotation of the conveying tank 6, under the action of the guide plate 8, it gradually moves to the discharge port 7 to realize the output of qualified materials. The whole process realizes the separation of qualified materials from substandard materials, so that the crushing tank 3 is always filled with substandard materials, and the grinding part 4 only grinds substandard materials. The qualified materials have been filtered into the conveying tank 6, so the qualified materials will not hinder the grinding of the grinding part 4, thereby improving the grinding efficiency of the grinding part 4. Compared with the traditional technology, the present technical solution can separate the particles that meet the requirements from the materials when working, thereby freeing up space for the remaining particles, and also makes the grinding part 4 not be disturbed when grinding the remaining particles, thereby improving the grinding efficiency of the ball mill.

[0033] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
