[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0037] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a silicate cement screening device, comprising a screening chamber 1, a feeding port 3 is connected to the right side of the top of the screening chamber 1, a box cover 4 is rotatably connected to the top of the screening chamber 1, screening plates 5 evenly distributed from top to bottom are fixedly connected to the inside of the screening chamber 1, a plurality of screening plates 5 are provided with a feed chute 6 on the top, a plurality of screening outlets 7 are connected to the left side of the screening chamber 1, a feed port 8 is connected to the bottom of the screening chamber 1, a fixing block 9 is fixedly connected to the bottom of the fixing block 9, a vibration motor 10 is fixedly connected, and a noise reduction mechanism 2 is provided on the outer wall of the screening chamber 1.
[0038] Specifically, the raw materials are placed through the feed port 3 on the screening chamber 1, and a plurality of screening plates 5 are fixed inside the screening chamber 1. The screening plates 5 are designed with a side convex shape, which can effectively slow down the speed of the raw materials passing through the screening plates 5. A plurality of evenly distributed feed troughs 6 are provided on the top of the screening plates 5, and the raw materials of different particle sizes are screened from top to bottom through the feed troughs 6. The screened raw materials flow out through different screening outlets 7, and the finest raw materials flow out through the feed port 8 at the bottom of the screening chamber 1. When the raw materials are screened, the entire screening chamber 1 is vibrated by starting the vibration motor 10 at the bottom of the screening chamber 1, which is more effective for screening the raw materials.
[0039] Reference Figure 1 and Figure 3The noise reduction mechanism 2 includes a plurality of fixed plates 201, and the opposite sides of the plurality of fixed plates 201 are fixedly connected to the opposite sides of the screening chamber 1, and the bottoms of the plurality of fixed plates 201 are fixedly connected to connecting columns 202. The outer walls of the plurality of connecting columns 202 are slidably connected to support columns 203, the inner bottoms of the plurality of supporting columns 203 are fixedly connected to buffer pads 204, the tops of the plurality of buffer pads 204 are fixedly connected to springs 205, the tops of the plurality of springs 205 are fixedly connected to the bottom ends of the connecting columns 202, the inner walls of the plurality of supporting columns 203 are fixedly connected to sound insulation layers 206, the tops of the plurality of supporting columns 203 are fixedly connected to sealing rings 207, and the outer walls of the plurality of connecting columns 202 are slidably connected to the inner sides of the sealing rings 207. Multiple adjacent support columns 203 are fixedly connected with support frames 208, the top left and right sides of the multiple support frames 208 are fixedly connected with reinforcement plates 209, the farthest sides of the multiple reinforcement plates 209 are fixedly connected to the opposite side of the support column 203, and the bottoms of the multiple support columns 203 are fixedly connected with sound insulation pads 210.
[0040] Specifically, multiple fixed plates 201 are fixed on both sides of the screening chamber 1, and the support column 203 and the fixed plate 201 are connected by a connecting column 202. A buffer pad 204 is fixed to the inner bottom of the support column 203, and a spring 205 is fixed to the top of the buffer pad 204. When the screening chamber 1 vibrates, the spring 205 inside the support column 203 cooperates with the buffer pad 204 for buffering. The buffer pad 204 is made of rubber material and can reduce the impact and vibration between moving parts and prevent them from being transmitted to the surrounding environment or adjacent structures. This can greatly reduce the impact of the connecting column 202 on the support column 203. At the same time, a sound insulation layer 206 is fixed on the inner wall of the support column 203. The sound insulation layer 206 is made of rubber material, which can effectively isolate vibration and reduce noise transmission. The spring 205 is squeezed in the sound insulation layer 206, which can reduce the noise generated by the spring 205. At the same time, the sealing ring 207 on the support column 203 is used to seal the gap between the connecting column 202 and the support column 203.
[0041] In addition, by installing sound insulation pads 210 at the bottom of the support columns 203, the sound insulation pads 210 have a strong sound insulation effect, thereby reducing the vibration sound generated by the support columns 203 and the ground. Among them, the support columns 203 are connected by support frames 208, and multiple reinforcement plates 209 are used to improve the stability and firmness of the entire device, so that the entire device can remain stable during operation and avoid shaking or tilting. At the same time, the support frame 208 also fully considers the load-bearing and force-bearing conditions of the device, and is made of high-strength materials and advanced processes, ensuring that the connection between the support columns 203 is firm and reliable, and can withstand greater pressure and shear force.
[0042] Reference Figure 1 and Figure 2 A switch box 11 is fixedly connected to the front side of the screening chamber 1, a dust cover 12 is rotatably connected to the front side of the switch box 11, the switch box 11 is electrically connected to the vibration motor 10, and a lifting ring 13 is fixedly connected to the front and rear sides of the screening chamber 1.
[0043] Specifically, the switch box 11 can facilitate users to accurately control the operating equipment on the entire device. A dust cover 12 is connected to the front side of the switch box 11. The dust cover 12 can effectively reduce the dust from entering the interior of the switch box 11 and causing damage to the components inside the switch box 11. Lifting rings 13 are fixed on both sides of the screening chamber 1 to ensure the stability of the device during transportation.
[0044] Working principle: First, when screening the cement raw materials, pour the raw materials through the feed port 3 on the screening chamber 1, and then start the vibration motor 10 at the bottom of the screening chamber 1 to screen the raw materials on the screening plate 5. The top of the screening plate 5 is designed with a side convex shape, which can effectively slow down the flow speed of the raw materials, so that the raw materials can be fully screened and filtered on the screening plate 5. The filtered raw materials flow down through the discharge trough 6 on the screening plate 5, and after screening layer by layer, different raw material particles finally flow out through the screening outlet 7 and the discharge port 8 for use;
[0045] When the whole device is noise-reduced, the screening chamber 1 is fixed by the fixing plate 201, and the fixing plate 201 is connected to the support column 203 by the connecting column 202. When vibrating, the impact of the vibration is offset by the spring 205 inside the support column 203 and the buffer pad 204. At the same time, the spring 205 will generate a lot of noise when it is continuously squeezed. At this time, the noise generated by the spring 205 is isolated by the sound insulation layer 206 inside the support column 203, and the connection between the connecting column 202 and the support column 203 is sealed by the sealing ring 207, so that a lot of noise generated by the device during operation can be reduced, thereby improving the quality of the working environment.
[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
