It has good binding and durability and is widely used in construction projects such as concrete, mortar, blocks, and bricks. Cement grinding refers to the process of finely grinding cement clinker through grinding equipment to achieve a certain fineness requirement. The purpose of cement grinding is to increase the surface area of ​​cement, improve its activity, and enhance its binding properties, thereby improving the strength and durability of concrete.

[0003] For example, the grinding device for cement processing disclosed in Chinese invention patent / utility model patent (application number: CN222401595U) includes a grinding cylinder, a first grinding column and a second grinding column are sleeved on the inner arc surface of the grinding cylinder, the first grinding column is set on the top of the second grinding column, a first funnel groove is opened in the center of the first grinding column, a second funnel groove is opened in the center of the second grinding column, a first conical grinding column and a second conical grinding column are rotatably connected in the first funnel groove and the second funnel groove respectively, and a rotating mechanism for rotating the first conical grinding column and the second conical grinding column is provided inside the grinding cylinder.

[0004] Although the above patents can make the grinding finer, the above devices still have the following problems: During the use of the device, since the device directly grinds the material, when the material is damp, it is easy for the material to stick together, which reduces the grinding quality of the material and affects the subsequent processing of the material. Therefore, we have made improvements to this and proposed a solid waste raw material grinding device. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when materials are damp, they tend to stick together, which reduces the grinding quality of the materials.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a solid waste raw material grinding device, comprising a device body, a first support frame fixedly connected to the top of the device body, a motor fixedly connected to the top of the first support frame, the output end of the motor rotatably passing through the top of the first support frame and extending to the outside of the first support frame, a rotating shaft fixedly connected to the output end of the motor via a coupling, the bottom end of the rotating shaft rotatably passing through the top of the device body and extending to the interior of the device body, a cylinder fixedly connected to the upper surface inside the device body, a power shaft rotatably connected to the interior of the device body extending to the interior of the cylinder, the interior of the power shaft having a hollow structure, a drying and dispersing device provided on the top of the device body, and a rotating frame fixedly connected to the outer surface of the rotating shaft.

[0007] As a preferred technical solution of this application, the drying and dispersing device includes a second support frame, the bottom of the second support frame is fixedly connected to the top of the equipment body, a gas box is fixedly connected to the top of the second support frame, the interior of the gas box is a hollow structure, a fan is installed on the gas box, the exhaust end of the fan is connected to the interior of the gas box, the top of the power shaft rotates through the interior of the second support frame and extends into the interior of the gas box, and a stirring rod is fixedly connected to the power shaft.

[0008] As a preferred technical solution of this application, the bottom plate of the rotating frame is provided with mesh holes.

[0009] As a preferred technical solution of this application, the gas box is provided with an exhaust groove, and a filter plate is provided inside the exhaust groove.

[0010] As a preferred technical solution of this application, sprockets are fixedly connected to both the rotating shaft and the power shaft, and chains are meshed with the outer surfaces of the sprockets.

[0011] As a preferred technical solution of this application, the two sprockets are driven by a chain.

[0012] As a preferred technical solution of this application, a support rod is fixedly connected inside the device body, and a disturbance rod is fixedly connected to the bottom of the support rod.

[0013] As a preferred technical solution of this application, a base plate is fixedly connected to the bottom end of the power shaft, and the base plate is frustum-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. By setting up a fan, power shaft, stirring rod, and filter plate, the power shaft drives the stirring rod to rotate, which can break up the raw material. At the same time, the hot air inside the gas box enters the inside of the power shaft and is discharged through the filter plate to heat and dry the material. This allows the material to be ground more smoothly and reduces the occurrence of material sticking together due to moisture to a certain extent, making the material easier to grind.

[0017] 2. The base plate and rotating frame enable the discharged material to be dispersed, allowing it to fall more evenly into the rotating frame. The rotating frame then scatters the material, ensuring more uniform grinding. The rotating shaft drives the rotating frame to rotate, causing the disturbance rod to agitate the material inside and facilitate its smoother fall. This makes subsequent grinding more convenient and ensures a certain level of grinding quality. Attached Figure Description

The rotating frame 16 is set on the upper side of the grinding structure. The material can be poured out through the rotating frame 16, and the material can be ground more evenly.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3, Figure 4 As shown, the drying and dispersing device includes a second support frame 9, the bottom of which is fixedly connected to the top of the equipment body 1. A gas box 10 is fixedly connected to the top of the second support frame 9. The gas box 10 has a hollow interior and is equipped with heating pipes to heat the gas. A fan 18 is mounted on the gas box 10. The fan 18 is an existing structure and will not be described in detail here. The exhaust end of the fan 18 is connected to the interior of the gas box 10, allowing gas from the external environment to be introduced into the gas box 10 and heated.

At the same time, the power shaft 8 can rotate, and the power shaft 8 drives the stirring rod 11 to rotate, which can make the stirring rod 11 break up the raw material. At the same time, the hot air inside the gas box 10 enters the interior of the power shaft 8 and is discharged through the filter plate 17, which can heat and dry the material, so that the material can be ground more smoothly and to a certain extent reduce the occurrence of material sticking together due to moisture, so that the material can be ground more smoothly.

[0036] The bottom plate 13 allows the discharged material to be dispersed, so that the material can fall more evenly into the interior of the rotating frame 16. The rotating frame 16 can scatter the material and make it more evenly ground. The rotating shaft 4 drives the rotating frame 16 to rotate, so that the disturbance rod 15 can disturb the material inside the rotating frame 16 and make the material fall more smoothly, making the subsequent grinding process of the material more convenient and ensuring the grinding quality of the material to a certain extent.
