Description
技术领域technical field
本实用新型属于化工领域，具体涉及一种方便出料的磨机。The utility model belongs to the field of chemical industry, and in particular relates to a mill for convenient discharging.
背景技术Background technique
矿石开采后，需要使用磨机将矿石原料磨至一定的粒径，磨过后的矿石再进入滚筒筛进行筛选，粒径符合要求的矿粒经过筛孔出料，粒径过大的矿粒则需要返回至磨机重新磨矿，直至达到要求；传统生产中，粒径过大的矿粒经过收集，由工人操作重新投入磨机，磨机投料量越大，产生的大粒径矿粒越多，人工操作越平凡，这在很大程度上增加了工人的劳动强度，并在一定程度上降低了生产效率，因此，需要对粒径过大的矿粒进行机械化处理，使其从筛网回到磨机的过程由机械设备代替。After the ore is mined, it is necessary to use a mill to grind the ore raw material to a certain particle size, and then the ground ore enters the drum screen for screening. It is necessary to return to the mill to re-grind the ore until it meets the requirements; in traditional production, the ore particles with too large particle size are collected and put into the mill again by the workers. The more the manual operation is, the more ordinary it is, which increases the labor intensity of the workers to a large extent and reduces the production efficiency to a certain extent. The process of going back to the mill is replaced by mechanical equipment.

为解决以上技术问题，本实用新型提供一种将大粒径矿粒自动回送的磨机。In order to solve the above technical problems, the utility model provides a mill for automatically returning large-diameter ore particles.
技术方案如下：The technical solution is as follows:
一种磨机，包括磨机本体，其关键在于：在所述磨机本体的出料口连接有出料装置，该出料装置包括出料筒和滚筒筛，其中所述出料筒包括第一筒体和第一螺旋片，所述第一螺旋片安装在所述第一筒体的内壁上，所述滚筒筛包括第二筒体和第二螺旋片，所述第二螺旋片安装在所述第二筒体的内壁上，在所述第二筒体上开设有筛孔，所述第一筒体的一端和第二筒体的开口对接，另一端与所述磨机本体的出料口连接，所述第一筒体和第二筒体的内径相等，所述第一筒体和第二筒体的旋转方向一致，所述第一螺旋片旋向和第二螺旋片的旋向相反，所述第二螺旋片的高度大于所述第一螺旋片的高度。该设计方案的显著效果是，传统的出料筒和滚筒筛的旋转方向与磨机的旋转方向是一致的，一般都为左旋，出料筒和滚筒筛内的螺旋片旋向也是一致的，矿粒按同一顺序排出，矿粒经过滚筒筛的筛选，粒径过大的矿粒在滚筒筛的下料端排出；而通过调整出料筒和滚筒筛内的螺旋片旋向，使磨机来料在出料筒内向前运送，磨机来料在滚筒筛内向后运送，滚筒筛内的螺旋片高度大于出料筒螺旋片的高度，这样，粒径符合要求的矿粒经过滚筒筛的筛选出料，粒径过大的矿粒则会返回磨机重新磨矿，直至大粒径矿粒被磨至符合要求的规格；本设计中通过对滚筒筛进行微小改进，调整对应关系就解决了大粒径矿粒返回磨机的问题，结构简单，实用性强，大大降低了工人的劳动强度。A mill, comprising a mill body, the key lies in: a discharge device is connected to the discharge port of the mill body, the discharge device includes a discharge cylinder and a trommel screen, wherein the discharge cylinder includes a first A cylinder and a first spiral piece, the first spiral piece is installed on the inner wall of the first cylinder, the trommel screen includes a second cylinder and a second spiral piece, the second spiral piece is installed on the On the inner wall of the second cylinder, a screen hole is opened on the second cylinder, one end of the first cylinder is docked with the opening of the second cylinder, and the other end is connected with the outlet of the mill body. The feed port is connected, the inner diameters of the first cylinder and the second cylinder are equal, the rotation directions of the first cylinder and the second cylinder are consistent, and the rotation direction of the first helical piece is the same as that of the second helical piece. On the contrary, the height of the second spiral sheet is greater than the height of the first spiral sheet. The remarkable effect of this design scheme is that the rotation direction of the traditional discharge cylinder and trommel screen is consistent with the rotation direction of the mill, generally left-handed, and the rotation direction of the spiral pieces in the discharge cylinder and trommel screen is also consistent. The ore particles are discharged in the same order. The ore particles are screened by the trommel screen, and the ore particles with too large particle size are discharged at the discharge end of the trommel screen; The incoming material is conveyed forward in the discharge cylinder, and the incoming material of the mill is conveyed backward in the trommel screen. The height of the spiral piece in the trommel screen is greater than that of the discharge cylinder spiral piece. Screen out the material, and the ore particles with too large particle size will be returned to the mill for re-grinding until the large-size ore particles are ground to meet the required specifications; in this design, the trommel screen is slightly improved and the corresponding relationship is adjusted to solve the problem It solves the problem of large-size ore particles returning to the mill, has a simple structure and strong practicability, and greatly reduces the labor intensity of workers.
上述第一筒体和第二筒体固定连接，所述第一筒体和第二筒体同步转动。采用以上方案，第一筒体和第二筒体可以由同一动力源带动，简化了结构。The first cylinder and the second cylinder are fixedly connected, and the first cylinder and the second cylinder rotate synchronously. With the above solution, the first cylinder and the second cylinder can be driven by the same power source, which simplifies the structure.
