Description

Technical Field

[0001] This utility model belongs to the technical field of KR desulfurizer production equipment, specifically relating to a raw material grinding equipment for preparing calcium oxide-based KR desulfurizer. Background Technology

[0002] In the steelmaking process, the KR desulfurization process is widely used due to its high desulfurization efficiency and strong stability. Calcium oxide-based KR desulfurizer is the core raw material of this process. The preparation of calcium oxide-based KR desulfurizer requires grinding raw materials such as limestone and dolomite to achieve a specific particle size requirement (usually controlled between 80-200 mesh). The uniformity and fineness of the raw material particle size directly affect the efficiency of the subsequent desulfurization reaction. For example, a raw material grinding device with application number "CN202420341323.6" includes a hopper, a crushing mechanism, a grinding mechanism, and a drive mechanism. Support legs are provided at the bottom of the hopper. The crushing mechanism is fixedly mounted on the top of the hopper. The grinding mechanism is rotatably mounted inside the hopper. The drive mechanism is fixedly mounted on one side of the hopper to drive the crushing and grinding mechanisms to rotate. The raw material grinding device described in this utility model, through the crushing mechanism, can crush raw materials of different particle sizes into materials of the same size, facilitating grinding operations. Through the grinding mechanism, the crushed raw materials can be ground into powder or granules. Through the drive mechanism, the crushing and grinding mechanisms can be driven to rotate simultaneously, reducing the use of motors and avoiding space occupation. Through the cover plate, the discharge is ensured to be controlled, preventing material leakage.

[0003] Based on the aforementioned existing technology, it is known that traditional grinding equipment requires manual addition of materials to the grinding mechanism during the grinding operation. However, it is difficult to control the feeding speed when adding materials manually, which further makes it impossible to adjust the subsequent grinding speed and reduces grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a raw material grinding device for preparing calcium oxide-based KR desulfurizer, which can solve the problems mentioned in the background art.

[0005] The specific technical solution adopted in this utility model is as follows: A raw material grinding device for preparing calcium oxide-based KR desulfurizer includes a grinding mechanism. A support mechanism is fixedly connected to the outside of the grinding mechanism. There are two support mechanisms, and the two support mechanisms are fixedly connected to the left and right sides of the outer periphery of the grinding mechanism in opposite directions. Support plate assemblies are fixedly connected to the top surfaces of the two support mechanisms. Vertical plate mechanisms are fixedly connected to the top surfaces of the support plate assemblies. The vertical plate mechanisms are perpendicular to the support plate assemblies. A control motor is fixedly connected to the right side of the vertical plate mechanism. An input gear is installed on the left output shaft of the control motor. A guide shaft assembly is rotatably connected inside the support plate assembly through a bearing seat. A driven gear is fixedly connected to the top of the guide shaft assembly. A stirring assembly is fixedly connected to the outside of the guide shaft assembly.

[0006] The present invention is further configured such that both the driven gear and the input gear are bevel gears, and the driven gear and the input gear mesh and transmit power together, forming a transmission structure.

[0007] The present invention is further configured such that: the main body of the grinding mechanism is a frustoconical structure with a thicker upper part and a thinner lower part; a feeding pipe is fixedly connected to the bottom end of the grinding mechanism; the feeding pipe communicates with the grinding mechanism; and a support leg assembly is fixedly connected to the bottom end surface of the grinding mechanism.

[0008] The present invention is further configured such that: the support leg assembly is arranged longitudinally, and there are three support leg assemblies in total, which are fixedly connected to the bottom end surface of the grinding mechanism in a circular array.

[0009] The present invention is further configured such that: a pad assembly is fixedly connected to the bottom surface of each of the three support leg assemblies, the support leg assemblies and the pad assembly together form a support structure for the grinding mechanism, and a filter plate assembly is fixedly connected to the inner side of the grinding mechanism.

[0010] The present invention is further configured such that: the filter plate assembly has through holes arranged in a ring array inside, the through holes being filter hole components, and a connecting bracket is fixedly connected to the outside of the support plate assembly.

[0011] The present invention is further configured such that: there are two connecting brackets, and the two connecting brackets are fixedly connected to the front and rear sides of the support plate assembly in opposite directions, and the side of the two connecting brackets away from the support plate assembly is fixedly connected to a feeding hopper.

[0012] The present invention is further configured such that: a feeding pipe is fixedly connected to the bottom end of the feeding hopper, the feeding pipe is located directly above the filter plate assembly, and a servo motor is installed on the outer wall of the feeding pipe, and a material plate assembly for controlling the feeding speed is installed on the output shaft of the servo motor.

[0013] The technical effects achieved by this utility model are as follows: This invention relates to a raw material grinding device for preparing calcium oxide-based KR desulfurizer. By installing a servo motor on the outer wall of the feeding pipe and using the servo motor to drive the material plate assembly to rotate, the feeding speed of the raw material can be precisely adjusted to match the grinding speed of the grinding mechanism. This effectively avoids the situation where the grinding efficiency decreases due to raw material accumulation or the equipment runs idle due to raw material interruption. Stable feeding can be achieved without manual intervention, significantly improving the continuity and automation of the grinding operation and solving the core technical problems of low efficiency and difficulty in controlling the speed of manual feeding.

[0014] This utility model discloses a raw material grinding device for preparing calcium oxide-based KR desulfurizer. Through a transmission structure consisting of a motor, input gear, and driven gear, the device drives the guide shaft assembly and stirring assembly to rotate. This ensures thorough stirring of the raw materials before they enter the grinding mechanism, resulting in uniform distribution and improved grinding uniformity. This, in turn, guarantees the quality of the subsequent desulfurizer preparation. Simultaneously, the symmetrical support of the support plate assembly by two support structures, along with the support structure composed of the support leg assembly and the pad assembly, provides a stable installation foundation for the vertical plate assembly and the entire grinding mechanism. This prevents displacement due to vibration during operation, further ensuring the stability and reliability of the grinding operation and solving the problems of poor grinding uniformity and insufficient operational stability in existing equipment.

[0016] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-6 As shown, a raw material grinding device for preparing calcium oxide-based KR desulfurizer includes a grinding mechanism 1. A support mechanism 2 is fixedly connected to the outside of the grinding mechanism 1. There are two support mechanisms 2, and the two support mechanisms 2 are fixedly connected to the left and right sides of the outer periphery of the grinding mechanism 1 in opposite directions. Support plate assemblies 201 are fixedly connected to the top surfaces of the two support mechanisms 2. Vertical plate mechanisms 3 are fixedly connected to the top surfaces of the support plate assemblies 201. The vertical plate mechanisms 3 and the support plate assemblies 201 are vertically arranged. A control motor 301 is fixedly connected to the right side of the vertical plate mechanism 3. An input gear 3011 is installed on the left output shaft of the control motor 301. A guide shaft assembly 3012 is rotatably connected inside the support plate assembly 201 through a bearing seat. A driven gear 3013 is fixedly connected to the top of the guide shaft assembly 3012. A stirring assembly 3014 is fixedly connected to the outside of the guide shaft assembly 3012. By setting support mechanisms 2 on both sides of the grinding mechanism 1 and installing vertical plate mechanisms 3 and control motors 301 on the support plate assemblies 201, and cooperating with the input gear 3011, guide shaft assembly 3012, driven gear 3013 and stirring assembly 3014, the automatic stirring and uniform mixing of raw materials during the grinding process can be realized, thereby improving the grinding efficiency and effect.

[0018] Furthermore, both the driven gear 3013 and the input gear 3011 are bevel gear structures, and the driven gear 3013 and the input gear 3011 mesh and transmit power, forming a transmission structure together. By using bevel gear meshing transmission between the input gear 3011 and the driven gear 3013, the power transmission is smooth and efficient, the structure is compact, and high-speed grinding operations can be achieved in a limited space.

[0019] Furthermore, the main body of the grinding mechanism 1 is a frustoconical structure with a thicker top and a thinner bottom. The bottom end of the grinding mechanism 1 is fixedly connected to a feeding pipe 101, which is connected to the grinding mechanism 1. A support leg assembly 1011 is fixedly connected to the bottom end surface of the grinding mechanism 1. By adopting a frustoconical structure with a thicker top and a thinner bottom and connecting the bottom to the feeding pipe 101, the grinding material can be discharged quickly. At the same time, the support leg assembly 1011 provides stable support to ensure the stability of the equipment operation.

[0020] The support leg assembly 1011 is arranged longitudinally, and there are three support leg assemblies 1011 in total. The three support leg assemblies 1011 are fixedly connected to the bottom surface of the grinding mechanism 1 in a ring array. The ring array arrangement of the three support leg assemblies 1011 effectively distributes the weight of the equipment, improves the overall stability, and adapts to the needs of long-term continuous grinding operations.

[0021] Furthermore, pad assemblies 1012 are fixedly connected to the bottom surfaces of the three support leg assemblies 1011. The support leg assemblies 1011 and the pad assemblies 1012 together form a support structure for the grinding mechanism 1. A filter plate assembly 1013 is fixedly connected to the inner side of the grinding mechanism 1. By adding pad assemblies 1012 to the bottom of the support leg assemblies 1011, the anti-slip and shock absorption effects are enhanced. Together with the filter plate assembly 1013, the grinding material is screened and graded to ensure uniform particle size.

[0022] The filter plate assembly 1013 has through holes arranged in a ring array inside, which are filter hole components 1014. A connecting bracket 2011 is fixedly connected to the outside of the support plate assembly 201. The filter hole components 1014 on the filter plate assembly 1013 are arranged in a ring array, which can accurately control the particle size of the material. At the same time, the connecting bracket 2011 strengthens the connection between the support plate assembly 201 and the feeding system.

[0023] Furthermore, there are two connecting brackets 2011, and the two connecting brackets 2011 are fixedly connected to the front and rear sides of the support plate assembly 201 in opposite directions. The side of the two connecting brackets 2011 away from the support plate assembly 201 is fixedly connected to the feeding hopper 2012. By symmetrically installing the two connecting brackets 2011 and connecting them to the feeding hopper 2012 respectively, the synchronous feeding on both sides can be achieved, thereby improving the raw material supply efficiency and reducing the waiting time during the grinding process.

[0024] Furthermore, a feeding pipe 2013 is fixedly connected to the bottom end of the feeding hopper 2012. The feeding pipe 2013 is located directly above the filter plate assembly 1013, and a servo motor 2014 is installed on the outer wall of the feeding pipe 2013. A material plate assembly 2015 for controlling the feeding speed is installed on the output shaft of the servo motor 2014. Since the feeding pipe 2013 is located directly above the filter plate assembly 1013, the servo motor 2014 drives the material plate assembly 2015 to precisely control the feeding speed, so that the grinding speed matches the feeding speed, avoids material accumulation or interruption of supply, and improves the overall production efficiency.

[0025] The working principle of this utility model is as follows: In use, firstly, the support leg assembly 1011 at the bottom of the grinding mechanism 1 and the pad assembly 1012 at the bottom of the support leg assembly 1011 together form a support structure, which stably supports the entire grinding equipment and prevents the equipment from shifting position due to vibration during operation; at the same time, the two support mechanisms 2 fixed to the left and right sides of the outer periphery of the grinding mechanism 1 provide vertical fixed support for the support plate assembly 201 at its top, ensuring that the support plate assembly 201 remains in a horizontal and stable state, laying the foundation for subsequent component installation and operation; The raw materials for preparing calcium oxide-based KR desulfurizer are added into the feed hopper 2012, which is fixed to the outside of the support plate assembly 201 by the connecting bracket 2011. Then, the servo motor 2014 installed on the outer wall of the feed pipe 2013 is started. The output shaft of the servo motor 2014 drives the material plate assembly 2015 to rotate. By adjusting the rotation angle of the material plate assembly 2015, the size of the raw material falling channel inside the feed pipe 2013 is changed, thereby precisely controlling the feeding rate of the raw material and making the raw material stably transported at a preset speed to the filter plate assembly 1013 located directly below the feed pipe 2013. The control motor 301 fixed on the right side of the upright plate mechanism 3 is activated. The output shaft on the left side of the control motor 301 drives the input gear 3011 mounted on it to rotate synchronously. Since the input gear 3011 and the driven gear 3013 fixed at the top of the guide shaft assembly 3012 are both bevel gears and mesh with each other, the rotational power of the input gear 3011 is transmitted to the driven gear 3013 through meshing transmission, driving the driven gear 3013 to rotate. When the driven gear 3013 rotates, it drives the guide shaft assembly 3012 fixedly connected to it to rotate. The guide shaft assembly 3012 is rotatably connected to the support plate assembly 201 through the bearing seat to ensure rotational stability. The stirring assembly 3014 fixed on the outside of the guide shaft assembly 3012 rotates together with the guide shaft assembly 3012 to stir the raw material above the filter plate assembly 1013, so that the raw material is evenly dispersed and avoids the accumulation of raw material. The raw materials, uniformly stirred by the stirring component 3014, are continuously pushed by the stirring component 3014 and reciprocate in contact with the filter plate assembly 1013 of the grinding plate structure in the grinding mechanism 1 to achieve automated grinding. The ground material enters the grinding mechanism 1 under its own gravity, and the grinding mechanism 1 grinds the raw materials. The ground raw materials fall to the filter plate assembly 1013, and the filter hole assembly 1014 opened inside the filter plate assembly 1013 screens the particle size of the ground raw materials. The raw materials that meet the requirements fall into the bottom of the grinding mechanism 1 through the filter hole assembly 1014, and are finally discharged from the equipment through the feed pipe 101 that is connected to the grinding mechanism 1, completing the raw material grinding process. Throughout the process, the upright plate mechanism 3 remains fixed in a vertical position with the support plate assembly 201, providing stable installation support for the control motor 301 and ensuring continuous and stable power transmission.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
