DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 The present invention provides a technical solution: a uniform distribution device for a fluidized bed chlorination furnace, including a furnace body 1, a conveying and driving device 2, and a linkage and leveling device 3. The overall structure of the uniform distribution device for a fluidized bed chlorination furnace in this application is compact and the functions are integrated.

[0023] The furnace body 1 serves as the main framework of the uniform distribution device for a fluidized bed chlorination furnace in this application. The inner cavity of the furnace body 1 provides a necessary space and environment for the fluidized bed chlorination reaction of hafnium oxide raw materials. Further, the linkage and leveling device 3 is slidably connected in the inner cavity of the furnace body 1. This design ensures that the raw materials can be evenly leveled during the reaction process, thereby improving the reaction efficiency and product quality.

[0024] As Figure 1 shown, the furnace body 1 has two feeding positions. A first feeding port is provided on one side wall of the furnace body 1 near the top surface of the furnace body 1, and the first feeding port leads to the first raw material; a second feeding port is provided at the connection between the furnace body 1 and the conveying and driving device 2, and the second feeding port leads to the second raw material.

[0025] The conveying and driving device 2 serves as the core component for power transmission. A cam 5 mechanism is provided at one end of the conveying and driving device 2, and the cam 5 is used to drive the linkage and leveling device 3 to perform periodic reciprocating motion to achieve dynamic leveling and mixing of the raw materials.

[0026] Specifically, the linkage and leveling device 3 is composed of three main parts: an upper sieve plate 31, a lower sieve plate 32, and an elastic connecting member 33. Among them, the bottom surface of the upper sieve plate 31 is elastically connected to the top surface of the lower sieve plate 32 through the elastic connecting member 33. This design not only ensures the stability of the sieve plate during the movement process, but also enables the raw materials to form an effective screening and leveling effect between the upper and lower sieve plates, further promoting the uniform progress of the reaction.

[0027] Among them, the structure of the elastic connecting member 33 is as Figure 3As shown, the elastic connecting member 33 is in the form of a sleeve rod. The elastic connecting member 33 includes a rod sleeve and a connecting rod. The rod sleeve is sleeved on the outer side wall of the connecting rod, and the connecting rod is slidably connected inside the rod sleeve. The top surface of the connecting rod is connected to the inner top surface of the rod sleeve through a spring. The design of the elastic connecting member 33 elastically connects the upper sieve plate 31 and the lower sieve plate 32, and can avoid damage caused by hard connection while transmitting power.

[0028] A snap ring 6 is arranged in the inner cavity of the furnace body 1, and the snap ring 6 is fixed at a preset position on the inner wall of the furnace body 1. Specifically, the snap ring 6 is made of a material with high strength, high temperature resistance and corrosion resistance, such as stainless steel or special alloy, to ensure stability and durability in the high-temperature chlorination reaction environment. The shape of the snap ring 6 matches the edge contour of the bottom surface of the upper sieve plate 31, and the bottom surface of the upper sieve plate 31 is firmly clamped with the snap ring 6. This clamping method not only ensures the accurate positioning of the upper sieve plate 31 in the inner cavity of the furnace body 1, but also allows the upper sieve plate 31 to move up and down in a certain range along the vertical direction when subjected to external forces such as the push of the cam 5, so as to realize the function of spreading the raw materials evenly. It should be noted here that the snap ring 6 is restored to the correct position when the upper sieve plate 31 drops, that is, the upper sieve plate 31 returns to the horizontal position, so that the upper sieve plate 31 can ensure that the initial position is horizontal in each vibration.

[0029] At the same time, the setting of the snap ring 6 also enhances the stability of the upper sieve plate 31, prevents it from shifting or shaking during the reaction process, and ensures the smooth progress of the production process.

[0030] The conveying and driving device 2 mainly includes three core components: a first motor 21, a driving housing 23 and an auger 24.

[0031] The first motor 21 serves as the power source of the conveying and driving device 2. The first motor 21 is a high-performance explosion-proof motor, which can adapt to the flammable and explosive gas environment that may be generated during the boiling chlorination production process of hafnium oxide. The driving end of the first motor 21 is tightly connected to one end of the auger 24 through the high-precision coupling 22 to ensure the stability and reliability of power transmission. The rotation speed of the first motor 21 can be accurately adjusted according to actual production requirements to control the conveying speed of the raw materials.

[0032] The transmission housing 23 is the support and protection structure of the conveying transmission device 2. It is made of a strong and durable metal material and is firmly fixed to the outer wall of the furnace body 1 by fasteners such as bolts. An inner cavity is provided inside the transmission housing 23, and the inner cavity of the transmission housing 23 communicates with the inner cavity of the furnace body 1 so that the raw materials can smoothly enter the inner cavity of the furnace body 1 from the transmission housing 23. The inner cavity surface of the transmission housing 23 is finely processed to ensure the smooth rotation of the auger 24 therein and reduce the friction and blockage of the raw materials during transportation.

[0033] The auger 24 is a key execution component of the conveying transmission device 2. It consists of a long shaft and spiral blades. The auger 24 is installed in the inner cavity of the transmission housing 23 through high-precision bearings and rotates under the drive of the first motor 21. At the same time, the other end of the auger 24 is fixedly connected to the cam 5. When the auger 24 rotates, the cam 5 also rotates, thereby pushing the linkage leveling device 3 to move up and down to achieve the leveling function of the raw materials.

[0034] In addition, the overall layout of the conveying transmission device 2 is carefully designed to ensure the coordinated cooperation and efficient operation among various components. The feeding port and discharging port of the transmission housing 23 are reasonably positioned to facilitate the addition and discharge of raw materials. As Figure 1 shown, a conical feeding bin is provided at the top of the transmission housing 23, and the raw materials fall into the inner cavity of the transmission housing 23 and are conveyed into the inner cavity of the furnace body 1 through the auger 24.

[0035] A rotatable auxiliary device 4 is carefully arranged in the inner cavity of the furnace body 1. The auxiliary device 4 is located directly above the upper sieve plate 31 to effectively assist in processing the raw materials on the upper sieve plate 31. The presence of the auxiliary device 4 aims to further optimize the distribution state of the raw materials on the upper sieve plate 31, enhance the contact effect between the raw materials and the reaction gas, thereby improving the efficiency and product quality of the hafnium oxide fluidized chlorination reaction. The auxiliary device 4 can also clear the raw material residues on the upper sieve plate 31 through frequent sweeping to avoid blockage of the upper sieve plate 31 caused by raw material residues.

[0036] The auxiliary device 4 is a highly integrated mechanical system, mainly composed of three core components: the second motor 41, the connecting rod 42, and the rotating brush 43.

[0037] The second motor 41 serves as the power driving source of the auxiliary device 4. The second motor 41 is a high-performance explosion-proof motor, with excellent high-temperature resistance and corrosion resistance, and can adapt to the complex and harsh working conditions during the production process of hafnium oxide boiling chlorination. The second motor 41 includes a fixed end and a driving end. The second motor 41 is fixedly connected to the top surface of the furnace body 1 to ensure that the second motor 41 will not shake or displace during operation. The driving end of the second motor 41 passes through the top surface of the furnace body 1 through a sealing structure and extends into the inner cavity of the furnace body 1 to provide power support for subsequent transmission components.

[0038] The connecting rod 42 is a key transmission component between the second motor 41 and the rotating brush 43. It is made of high-strength and high-rigidity metal materials to ensure that it will not deform or break during power transmission. The top end of the connecting rod 42 is tightly connected to the driving end of the second motor 41 through precision connectors such as couplings to ensure the high efficiency and stability of power transmission. The bottom end of the connecting rod 42 is fixedly connected to the top surface of the rotating brush 43 by means of welding or bolt connection to form an organic whole. In this application, the connecting rod 42 can adopt the same structure as the elastic connecting piece 33.

[0039] The rotating brush 43 is an execution component of the auxiliary device 4. The rotating brush 43 directly acts on the raw materials on the upper sieve plate 31. The bottom surface of the rotating brush 43 is in close contact with the top surface of the upper sieve plate 31. Driven by the second motor 41, the connecting rod 42 drives the rotating brush 43 to perform a rotational motion. The bristles of the rotating brush 43 are made of special wear-resistant and high-temperature-resistant materials, with good elasticity and toughness, and can effectively turn, stir and spread the raw materials on the upper sieve plate 31 during rotation, further promoting the uniform distribution of the raw materials, increasing the contact area between the raw materials and the reaction gas, and improving the reaction efficiency between the raw materials and the reaction gas.

[0040] In addition, the overall design of the auxiliary device 4 fully considers the coordinated cooperation with other components in the furnace body 1. During operation, parameters such as the rotation speed and rotation direction of the auxiliary device 4 can be flexibly adjusted according to actual production requirements to achieve the best production effect.

[0046] The third stage: Start the second motor 41 to drive the rotating brush 43 to rotate, further sweep and spread the raw materials, and also prevent caking;

[0047] Continuous operation:

[0050] The auxiliary device 4 continuously works to maintain the dispersed state of the materials;
