Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement production, and more specifically, to a device for adjusting the proportion of coal-fired slag in cement production. Background Technology
[0002] Cement, as a powdered hydraulic inorganic binder, forms a paste when mixed with water. It hardens in air or water and firmly binds materials such as sand and stone together, making it widely used in civil engineering, water conservancy, and national defense projects. Coal ash is a solid waste generated during coal combustion. Its chemical composition mainly includes silicon dioxide and aluminum oxide, and it contains unburned coal dust and residual carbon, which possesses a certain amount of calorific value.
[0003] In existing technologies, the cement production process requires the addition of coal slag. However, because the coal slag is not finely processed, its particle size is relatively large, making it difficult to mix and proportion with cement clinker, thus reducing mixing efficiency. Furthermore, due to the lack of precise proportioning equipment, multiple devices are needed for repeated proportioning, which is cumbersome and prone to errors, resulting in inaccurate proportioning of coal slag and inconvenience in use. Therefore, we propose an improvement by creating a coal slag proportioning adjustment device for cement. Utility Model Content
[0004] The purpose of this invention is to address the problem that the large particle size of existing coal-fired slag reduces the efficiency of mixing and proportioning; the process is complicated and prone to errors, resulting in inaccurate proportioning of coal-fired slag and inconvenience in use.
[0005] In order to achieve the above-mentioned utility model objectives and improve the above-mentioned problems, this utility model provides a coal slag ratio adjustment device for cement, including a support column, an adjustment component, and a compaction component. The top of the support column is provided with an adjustment component for adjusting the coal slag ratio, and the top of the adjustment component is provided with a compaction component for compacting the coal slag into fine pieces.
[0006] The adjustment assembly includes a material trough fixed to the top of a support column. A sliding groove is provided inside the material trough, and a material support frame is slidably connected inside the sliding groove. A connecting rod is fixedly connected to one side of the material support frame, and a telescopic cylinder is fixedly connected to the bottom end of the connecting rod. A weight sensor is provided below the material support frame, and the weight sensor is electrically connected to a control panel. An actuator is electrically connected to the control panel.
[0007] As a preferred technical solution of this application, a feed inlet is provided at one end of the feed trough.
[0008] As a preferred technical solution of this application, a feed pipe is fixedly connected below the feed inlet.
[0009] As a preferred technical solution of this application, a buffer plate is fixedly connected inside the feed pipe.
[0010] As a preferred technical solution of this application, the angle between the buffer plate and the inner wall of the feed pipe is 60°.
[0011] As a preferred technical solution of this application, the compaction assembly includes a connecting column disposed above the material trough, a rotating rod rotatably connected to the top of the connecting column, a fixed plate fixedly connected to the surface of the rotating rod, a rotating groove formed on the side of the fixed plate, a rotating cylinder rotatably connected inside the rotating groove, a rotating plate fixedly connected to one end of the rotating rod through the interior of the rotating cylinder, a fixed rod fixedly connected to the bottom end of the rotating plate, a compaction cylinder rotatably connected to the surface of the fixed rod, and a first drive motor rotatably connected to the other end of the rotating rod.
[0012] As a preferred technical solution of this application, the rotating cylinder has screening holes on its surface.
[0013] As a preferred technical solution of this application, a second drive motor is fixedly connected to one end of the rotating cylinder.
[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. Through the set rotating drum, crushing drum, and through hole, coal slag is manually put into the rotating drum. The second drive motor drives the rotating drum to rotate, and gravity causes the slag to tumble and fall to the bottom of the drum. Then, the first drive motor is started, and the crushing drum is driven to rotate through the transmission mechanism to crush the coal slag in the rotating drum. The crushed slag falls into the adjustment component below through the through hole. This realizes the tumbling and crushing of coal slag, improves the mixing ratio efficiency, and solves the problem that the process in the existing technology is complicated and prone to errors, resulting in inaccurate proportioning of coal slag and inconvenience in use.
[0017] 2. Through the set weight sensor, the bearing frame and the actuator, the finely crushed coal slag in the rotating drum falls into the bearing frame. After the weight sensor reaches the preset weight ratio, the signal is transmitted to the control panel. The control panel instructs the actuator to start the telescopic motor, push the bearing frame above the feed inlet, and the slag falls into the feed pipe. After being decelerated by the buffer plate, it enters the mixing and proportioning equipment. This realizes the turning and crushing of coal slag, improves the mixing and proportioning efficiency, and solves the problem that the large particle size of coal slag in the existing technology reduces the mixing and proportioning efficiency.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] Example
[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A device for adjusting the proportion of coal slag in cement, comprising a support column 1, an adjustment component 2, and a compaction component 3. The top of the support column 1 is provided with an adjustment component 2 for adjusting the proportion of coal slag, and the top of the adjustment component 2 is provided with a compaction component 3 for compacting the coal slag into fine pieces.
[0030] The adjusting assembly 2 includes a material trough 201 fixed to the top of the support column 1. A sliding groove 202 is formed inside the material trough 201, and a material support frame 203 is slidably connected inside the sliding groove 202. A connecting rod 204 is fixedly connected to one side of the material support frame 203, and a telescopic cylinder 205 is fixedly connected to the bottom end of the connecting rod 204. A weight sensor 206 is installed below the material support frame 203, and the weight sensor 206 is electrically connected to a control panel 207. The control panel 207 is electrically connected to an actuator 208. When the finely crushed coal ash falls from inside the upper rotating cylinder 304, the coal ash falls into the material support frame 203, causing the material support frame 203 to... The weight sensor 206 of the container begins to sense the weight accumulated inside its material support frame 203. When the weight sensor 206 senses the weight that needs to be proportioned, it transmits an electrical signal to the control panel 207 via an electrical connection. Subsequently, the control panel 207 controls the actuator 208 to start the telescopic motor via an electrical connection, causing the telescopic end of the telescopic cylinder 205 to extend and push the material support frame 203 toward the feed inlet 4. When the material support frame 203 is pushed above the feed inlet 4, the coal slag inside the material support frame 203 falls into the feed pipe 5. The feed pipe 5 is buffered by the buffer plate 6 to reduce the speed at which the coal slag falls into the mixing and proportioning equipment. This allows for sensing and adjustment of the coal slag feed rate, making it convenient to use.
[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the compaction assembly 3 includes a connecting column 301 disposed above the material trough 201. A rotating rod 302 is rotatably connected to the top of the connecting column 301. A fixed disk 303 is fixedly connected to the surface of the rotating rod 302. A rotating groove is formed on the side of the fixed disk 303. A rotating cylinder 304 is rotatably connected inside the rotating groove. One end of the rotating rod 302 passes through the interior of the rotating cylinder 304 and is fixedly connected to a rotating plate 305. A fixed rod 306 is fixedly connected to the bottom end of the rotating plate 305. A compaction cylinder 307 is rotatably connected to the surface of the fixed rod 306. A first drive motor 308 is rotatably connected to the other end of the rotating rod 302. In use, coal ash is manually placed inside the rotating cylinder 304, and then the second drive motor 308 is rotated. The drive motor 8 drives the rotating drum 304 to rotate, which in turn drives the coal slag inside the rotating drum 304 to rotate. Due to gravity, when the coal slag rotates to the upper part inside the rotating drum 304, it begins to flip and fall to the bottom of the rotating drum 304. Then, the first drive motor 308 is started, which drives the rotating rod 302 to rotate. The rotating rod 302 then drives the rotating plate 305 to rotate, which in turn drives the crushing drum 307 to rotate. The crushing drum 307 begins to crush and pulverize the coal slag inside the rotating drum 304. The crushed coal slag then falls through the through hole into the adjusting component 2 below. This process of flipping and crushing the coal slag improves the mixing efficiency.
[0032] The usage process of the cement slag proportioning adjustment device provided by this utility model is as follows:
[0033] In operation, the coal ash is manually placed inside the rotating drum 304. Then, the second drive motor 8 is rotated, causing the rotating drum 304 to rotate. The rotating drum 304 then rotates the coal ash inside. Due to gravity, when the coal ash reaches the upper part of the rotating drum 304, it begins to tumble and fall to the bottom. Then, the first drive motor 308 is activated, causing the rotating rod 302 to rotate. The rotating rod 302 then rotates the rotating plate 305, which in turn rotates the crushing drum 307. The crushing drum 307 then begins to crush and finely pulverize the coal ash inside the rotating drum 304. The crushed coal ash then falls through the through-hole into the adjusting assembly 2 below. When the finely crushed coal slag inside the upper rotating drum 304 falls into the material receiving frame 203, the weight sensor 206 below the material receiving frame 203 begins to sense the weight accumulated inside the material receiving frame 203. When the weight sensor 206 senses the weight that needs to be proportioned, it transmits an electrical signal to the control panel 207 via an electrical connection. Subsequently, the control panel 207 controls the actuator 208 to start the telescopic motor via an electrical connection, causing the telescopic end of the telescopic cylinder 205 to extend and push the material receiving frame 203 towards the feed inlet 4. When the material receiving frame 203 is pushed above the feed inlet 4, the coal slag inside the material receiving frame 203 falls into the feed pipe 5, and the speed at which it falls into the mixing and proportioning equipment is reduced by the buffer plate 6 inside the feed pipe 5.
