[0025] See also Figures 1 to 3, now an activated liner for a solid waste mill provided by the utility model is described. The activated liner for a solid waste mill comprises a top plate 1 and a side plate 2 which are arranged perpendicularly to each other, the top plate 1 is mounted and fixed on the inner wall of the mill drum, the side plate 2 comprises a first plate body 21 and a second plate body 22 which are connected to each other, the first plate body 21 is arranged perpendicularly to the central axis of the mill drum, the first plate body 21 is penetrated by a discharge hole for the material to pass through, the second plate body 22 is located on one side of the first plate body 21, and is inclined toward the side facing the material, and has a return angle with the first plate body 21.
[0026] The utility model provides an activated liner for a solid and hazardous waste processing mill. Compared with the prior art, on the one hand, a first plate body 21 is provided to hinder the transmission of materials; on the other hand, a second plate body 22 is provided, and the second plate body 22 is inclined toward the side facing the materials, so that a material return angle is provided between the first plate body 21 and the second plate body 22. When the second plate body 22 rotates with the mill drum, the materials transmitted to the second plate body 22 will be subjected to the reverse action force of the second plate body 22, so that this part of the materials is transmitted in the reverse direction, forming a counter-action with the materials transmitted in the forward direction, thereby slowing down the flow speed of the materials.
[0027] In this embodiment, the return angle is between 120° and 150°. If the return angle is too large, the return effect of the second plate 22 will not be obvious. If the return angle is too small, it will easily cause materials to accumulate between the first plate 21 and the second plate 22.
[0028] In some embodiments, see Figures 1 to 3 The top plate 1 is an arc-shaped plate adapted to the side wall of the mill. A plurality of lifting ridges 11 are provided on the end surface of the top plate 1 facing the side plate 2. In the present embodiment, the cross section of the lifting ridge 11 is semicircular. The lifting ridge 11 is parallel to the central axis of the mill drum. A plurality of lifting ridges 11 are spaced apart along the width direction of the top plate 1. In the present embodiment, the width direction of the top plate 1 is perpendicular to the central axis of the mill drum. By providing the lifting ridges 11, in the process of the top plate 1 rotating with the mill drum, the lifting ridges 11 increase the friction between the top plate 1 and the grinding body and the material, enhance the lifting capacity of the top plate 1 to the grinding body and the material, and directly improve the operating efficiency of the mill.
[0029] In this embodiment, a mounting hole 12 penetrating the top plate 1 is provided on the end surface of the top plate 1 facing the side plate 2. The number of the mounting holes 12 is two, and the two mounting holes 12 are spaced and symmetrically arranged along the width direction of the top plate 1. In application, the top plate 1 can be bolted and fixed to the inner wall of the grinding mill drum by using bolts through the mounting holes 12.
[0030] In some embodiments, see Figures 1 to 3The discharge hole includes a first hole body 201 and a second hole body 202. The first hole body 201 is located in the upper half of the first plate body 21, and the cross-sectional area of the first hole body 201 is set to be not less than 1 / 2 of the cross-sectional area of the upper half of the first plate body 21. There are multiple second hole bodies 202, and the multiple second hole bodies 202 are evenly arranged in the lower part of the first plate body 21, and the sum of the cross-sectional areas of the multiple second hole bodies 202 is set to be smaller than the cross-sectional area of the first hole body 201. In practical applications, the cross-sectional areas of the multiple second hole bodies 202 in the lower half of the first plate body 21 are much smaller than those of the first hole body 201. The purpose of setting the second hole body 202 is to enable the material that meets the particle size requirements to be discharged through the second hole body 202 in time, thereby improving the working efficiency. In this embodiment, the cross-sectional area of the first hole body 201 is relatively much larger. On the one hand, the provision of the second hole body 202 reduces the weight of the entire activated liner, reduces the amount of materials used in the activated liner processing, and reduces the manufacturing cost. On the other hand, when the material in the mill drum is accumulated too high, the material can be quickly discharged through the first hole body 201, avoiding serious accumulation of materials in the mill drum and the problem of heavy operating load.
[0031] In this embodiment, in order to improve the flow effect of the first hole body 201 and the second hole body 202 , rounded corners are provided at the edges of the first hole body 201 and the second hole body 202 .
[0032] In some embodiments, see Figures 1 to 3 , the width of the second plate 22 is set to be greater than or equal to 2 / 3 of the width of the first plate 21, and the height of the second plate 22 is set to be 1 / 2 of the height of the first plate 21. If the length of the second plate 22 is too long, it will cause the second plate 22 to extend too much toward the side facing the material, so that the second plate 22 will bear too much impact from the grinding body and the material, resulting in a reduction in the service life of the second plate 22. In practical applications, the height of the material in the mill drum should not be piled too high. The height of the second plate 22 is set to half the height of the first plate 21, which can meet the material height requirements in the mill drum while reducing the amount of material used to make the activated lining plate and reducing the production cost.
[0033] Optionally, the top plate 1, the first plate body 21 and the second plate body 22 are integrally formed. In reality, the activated liner is usually made of wear-resistant metal materials through casting. During processing, the top plate 1, the first plate body 21 and the second plate body 22 are integrally formed, which can reduce the subsequent processing steps and improve the processing efficiency.
[0034] In some embodiments, see Figures 1 to 3In order to prevent the second plate body 22 from wearing too quickly during application, a protective structure is provided on the side wall of the second plate body 22 facing the material. Specifically, the protective structure includes a plurality of protrusion groups arranged at intervals along the width direction of the second plate body 22, each protrusion group includes a plurality of hemispherical protrusions 203 longitudinally spaced on the second plate body 22, and similar hemispherical protrusions 203 in two adjacent protrusion groups are staggered with each other.
[0035] In practical applications, by providing the hemispherical protrusion 203 on the second plate 22, the abrasive and the grinding body can first contact the hemispherical protrusion 203 when colliding with the second plate 22, so that the hemispherical protrusion 203 bears most of the impact, thereby preventing the material and the grinding body from directly impacting the end surface of the second plate 22, causing the second plate 22 to wear too quickly. The above description is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
