Description

Technical Field

[0001] This utility model relates to the field of tin smelting fuming furnace technology, and in particular to a uniform feeding and sealed feeding device for a tin smelting fuming furnace. Background Technology

[0002] A fuming furnace is a device that blows a mixture of air and pulverized coal into liquid slag, causing certain valuable metals in the slag to volatilize in the form of metals, oxides, or sulfides. Fuming furnaces were originally used to process lead blast furnace slag, but they are also required for processing tin smelting.

[0003] A search of the Chinese patent "Uniform Feeding and Sealed Feeding Device for Tin Smelting Furnace" (publication number CN218210820U) reveals that this patent adjusts the material feeding area by controlling the distance between two movable plates, thereby changing the material feeding rate. Furthermore, by incorporating a uniform feeding component, the incoming material is stirred, ensuring its even distribution within the furnace body and preventing material accumulation that could affect the smelting efficiency of the fumigation furnace. The device uses a movable track and sliding block to move the two movable plates to opposite sides, adjusting the distance between them and thus regulating the material feeding area. The drive shaft 4 rotates the stirring blades to disperse the material. However, when conveying material through the gap between the two movable plates, material easily accumulates and clogs on the plates. Moreover, the gap between the plates controls the material's falling speed and efficiency, resulting in an unsatisfactory feeding effect and hindering efficient and uniform material conveying, ultimately reducing the device's feeding efficiency.

[0004] Therefore, a closed feeding device for uniform feeding in a tin smelting fuming furnace is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a closed feeding device for uniform feeding in a tin smelting fuming furnace in order to solve the above problems, thereby improving the problem of inconvenient and inefficient uniform material conveying.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a uniform feeding and sealed feeding device for a tin smelting fuming furnace, comprising a processing cylinder with a cylinder cover fixedly installed at the top; a feeding mechanism, which can quickly and uniformly convey materials, is disposed on the inner wall of the processing cylinder; wherein, the feeding mechanism includes an auger rotatably connected to the middle of the inner wall of the processing cylinder, a storage trough is opened at the top of the processing cylinder, the auger is rotatably connected to the bottom of the storage trough, a guide plate is fixedly connected to the bottom of the auger, and a stirring assembly is disposed at the bottom of the inner wall of the processing cylinder. The auger can uniformly convey the material in the storage trough, and the guide plate can guide and diffuse the material to prevent the material from accumulating in the processing cylinder, thus enabling uniform material conveying.

[0007] Preferably, the feeding mechanism further includes a rotating rod rotatably connected to the top of the auger. Two first stirring rods are fixedly connected to both sides of the rotating rod. The first stirring rods are rotatably connected to the storage tank. The rotating rod and the first stirring rods cooperate to stir the material in the storage tank, preventing it from accumulating and clogging in the storage tank.

[0008] Preferably, the top of the guide plate is provided with several evenly distributed guide grooves. The guide grooves on the guide plate can prevent the material from accumulating in the processing cylinder when falling and can disperse and distribute the material.

[0009] Preferably, a motor is fixedly installed at the top of the cylinder cover, and the output shaft of one end of the motor is fixedly connected to the rotating rod. The motor can drive the rotating rod and the auger to rotate, thereby improving the effectiveness of the device.

[0010] Preferably, a feeding groove is provided on one side of the top of the cylinder cover, and a sealing cap is snapped onto the top of the feeding groove. The feeding groove can hold materials, and the sealing cap can seal the feeding groove, thereby improving the sealing performance of the device.

[0011] Preferably, the stirring assembly includes a connecting rod rotatably connected to the bottom of the inner wall of the processing cylinder, and two second stirring rods are fixedly connected to both sides of the bottom of the connecting rod. The connecting rod and the second stirring rods cooperate to stir the material in the processing cylinder, which can prevent the material from accumulating and distribute the material evenly.

[0012] Preferably, a locking block is fixedly connected to the top end of the connecting rod, and the locking block is engaged with the bottom end of the guide plate. The connecting rod is connected to the guide plate through the locking block, and the connecting rod rotates along with the auger when it rotates.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up a feeding mechanism, the inner bottom wall of the storage trough is conical, which can guide the material and make it contact with the auger. As the auger rotates, the material can be conveyed. The material conveying efficiency can be controlled by controlling the rotation speed of the auger. When the auger rotates, it generates shearing force, which can crush and disperse the material to a certain extent, improving the processing effect of the device. The guide plate and the guide trough work together to disperse the material and prevent material accumulation. The rotating rod drives the first stirring rod to rotate to prevent material accumulation in the storage trough. The motor can drive the rotating rod and the auger to rotate. The sealing cover can seal the feed trough, which can uniformly feed the tin smelting fuming furnace and improve the material conveying efficiency.

[0015] 2. By setting up a stirring component, when the material falls into the processing cylinder, the connecting rod is embedded in the guide plate through the top locking block. The locking block is cross-shaped. When the auger drives the guide plate to rotate, the connecting rod rotates along with the locking block, driving the second stirring rod to stir the material in the processing cylinder, preventing material accumulation and improving the processing effect of the tin smelting fuming furnace on the material.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4As shown, a uniform feeding and sealed feeding device for a tin smelting fuming furnace includes a processing cylinder 1 with a cylinder cover 2 fixedly installed at its top; a feeding mechanism 3, capable of rapidly and uniformly conveying materials, is disposed on the inner wall of the processing cylinder 1; wherein, the feeding mechanism 3 includes an auger 301 rotatably connected to the middle of the inner wall of the processing cylinder 1, a storage trough 302 is opened at the top of the processing cylinder 1, the auger 301 is rotatably connected to the bottom end of the storage trough 302, and a guide plate 303 is fixedly connected to the bottom end of the auger 301. A stirring assembly 310 is provided at the bottom of the inner wall. When the auger 301 rotates, it can quickly convey the material in the storage tank 302. The auger 301 is located at the center column of the conical bottom of the storage tank 302, which can contact the material and improve the conveying effect. The material falls onto the guide plate 303 as the auger 301 moves downward. The conical guide plate 303 can guide and disperse the material, which can quickly and evenly convey the material to the tin smelting fuming furnace and improve the smelting effect of the tin smelting fuming furnace on the material.

[0023] like Figure 2 and Figure 3 As shown, the feeding mechanism 3 also includes a rotating rod 304 rotatably connected to the top of the auger 301. Two first stirring rods 305 are fixedly connected to both sides of the rotating rod 304. The first stirring rods 305 are rotatably connected to the storage tank 302. Several evenly distributed guide grooves 306 are opened at the top of the guide plate 303. A motor 307 is fixedly installed at the top of the cylinder cover 2. The output shaft of one end of the motor 307 is fixedly connected to the rotating rod 304. A feed groove 308 is opened on one side of the top of the cylinder cover 2. A sealing cap 309 is snapped onto the top of the feed groove 308. 307 can drive the first stirring rod 305 on the rotating rod 304 to rotate and stir the material in the storage tank 302, preventing the material from accumulating and clogging in the storage tank 302. When the rotating rod 304 rotates, it drives the auger 301 to transport the material. The guide plate 303 and the guide trough 306 cooperate to guide and disperse the material. The material enters the processing cylinder 1 through the feed trough 308 on the cylinder cover 2, which can place and store the material, improve the material conveying efficiency of the device, and improve the material utilization effect of the tin smelting fuming furnace.

[0024] like Figure 4As shown, the stirring assembly 310 includes a connecting rod 3101 rotatably connected to the bottom of the inner wall of the processing cylinder 1. Two second stirring rods 3102 are fixedly connected to both sides of the bottom of the connecting rod 3101. A locking block 3103 is fixedly connected to the top of the connecting rod 3101. The locking block 3103 is locked to the bottom of the guide plate 303. When the auger 301 drives the guide plate 303 to rotate, the connecting rod 3101 rotates along with the cross-shaped locking block 3103 in the mounting section, driving the second stirring rods 3102 to stir the material in the processing cylinder 1, preventing the material from accumulating in the processing cylinder 1, and improving the smelting effect of the tin smelting furnace on the material.

[0025] In use, the material enters the storage tank 302 through the feed trough 308. The controller drives the motor 307 to rotate the first stirring rods 305 on both sides of the rotating rod 304 to stir the material and prevent it from accumulating. At the same time, the rotating rod 304 drives the auger 301 to rotate, which contacts the material and conveys it to the bottom of the processing cylinder 1. The material contacts the guide plate 303. The guide plate 303 cooperates with the guide trough 306 to guide and disperse the material. The material falls into the processing cylinder 1. The guide plate 303 drives the connecting rod 3101 and the second stirring rods 3102 on both sides to rotate through the locking block 3103 to stir the material. When the material is processed in the tin smelting fuming furnace, the sealing cover 309 is then locked onto the feed trough 308 to seal it.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
