Description

Technical Field

[0001] This utility model belongs to the field of waste salt treatment technology, specifically relating to a high-temperature melting furnace for waste salt. Background Technology

[0002] Waste salt refers to wastewater containing large amounts of inorganic salts generated during chemical production processes. The high inorganic salt content in this wastewater can cause serious environmental pollution if directly discharged into the environment. Therefore, waste salt treatment is essential. Waste salt fusion heat treatment is a method that heats the waste salt to a high temperature, causing it to melt and decompose. This method decomposes the inorganic salts in the waste salt into oxides, chlorides, and other substances, thereby purifying the wastewater. Simultaneously, this method can also burn off the organic matter in the waste salt, thus reducing the environmental impact of organic matter.

[0003] According to patent number CN202322915403.6, a high-temperature melting furnace for waste salt treatment includes: a vertically placed furnace body, and a stirring mechanism and a collecting mechanism are arranged inside the furnace body. The stirring mechanism includes a furnace cover fixed to the top of the furnace body by bolts and a reaction cylinder arranged inside the furnace body parallel to the furnace body. A vertically placed long cylindrical rod is arranged inside the furnace cover.

[0004] The above-mentioned solution has certain technical defects in actual use. Since the scraper is only set on the side, it can only scrape and clean the side wall of the furnace body, and it is difficult to act on the bottom, resulting in the adhesion of solid salt at the bottom, which is not conducive to material discharge. Moreover, in the above-mentioned solution, since the large gear and the large disc rotate coaxially with the long cylindrical rod, and the rolling roller is installed on the large disc, the large disc rotates coaxially while the large gear rotates, so the meshing of the small gear and the large gear is in a fixed state. The large gear cannot drive the small gear to rotate, which makes the rolling roller unable to rotate, thus losing the function of turning the bottom material. Therefore, we propose a high-temperature melting furnace for waste salt. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature melting furnace for waste salt to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature melting furnace for waste salt, comprising a furnace body, an auger, and arc-shaped stirring rods. A furnace cover is provided on the top of the furnace body. A drive shaft is movably connected to the bottom center of the furnace cover via a bearing. An auger is spirally arranged around the outer periphery of the drive shaft. Multiple layers of arc-shaped stirring rods are also arranged around the outer periphery of the drive shaft. Side scrapers are fixedly connected to the ends of multiple arc-shaped stirring rods located on the same side of the drive shaft. A bottom scraper is provided on one side of the bottom of the side scraper. The end of the bottom scraper away from the side scraper is fixedly connected to the bottom of the drive shaft. The cross-sections of the side scraper and the bottom scraper are both triangular structures.

[0007] Preferably, a drive motor is fixedly installed at the top center of the furnace cover, and the end of the output shaft of the drive motor is fixedly connected to the top of the transmission shaft.

[0008] Preferably, the top two sides of the furnace body are fixedly installed with snap-fit ​​seats by welding, and the bottom two sides of the furnace cover are provided with snap-fit ​​rods. The furnace cover is fixedly snapped to the furnace body by the snap-fit ​​rods and snap-fit ​​seats.

[0009] Preferably, an observation port is provided at the middle of one side of the furnace body, and a control panel is installed below the side of the furnace body with the observation port.

[0010] Preferably, a discharge port is provided at the bottom of the other side of the furnace body, and a valve body is installed inside the discharge port.

[0011] Preferably, an exhaust port is provided at the top of the side of the furnace body away from the discharge port, and the exhaust port extends into the interior of the furnace body and communicates with the top of its interior.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting an arc-shaped stirring rod on the outer periphery of the drive shaft, the waste salt material is gathered towards the drive shaft while achieving a stirring effect. This, combined with the auger, tumbles the waste salt material from the bottom layer to the top layer, thereby improving the uniform heating of the waste salt material and enhancing the treatment effect and efficiency of the waste salt material.

[0014] 2. By setting a side scraper at the end of the arc-shaped stirring rod, in conjunction with the bottom scraper at the bottom of the drive shaft, the inner wall and bottom surface of the furnace can be scraped and cleaned, removing the solid waste salt adhering to the inner wall and bottom surface of the furnace, thereby improving the discharge effect and efficiency of waste salt materials, so that they can be fully decomposed and burned.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution for a high-temperature melting furnace for waste salt: it includes a furnace body 1, an auger 12, and arc-shaped stirring rods 13. A furnace cover 8 is provided on the top of the furnace body 1. A drive shaft 11 is movably connected to the bottom center of the furnace cover 8 via a bearing. An auger 12 is spirally arranged around the outer periphery of the drive shaft 11. Multiple layers of arc-shaped stirring rods 13 are also arranged around the outer periphery of the drive shaft 11. Side scrapers 14 are fixedly connected to the ends of multiple arc-shaped stirring rods 13 located on the same side of the drive shaft 11. A bottom scraper 15 is provided on one side of the bottom. The end of the bottom scraper 15 away from the side scraper 14 is fixedly connected to the bottom of the drive shaft 11. The cross-sections of the side scraper 14 and the bottom scraper 15 are both triangular structures. The arc-shaped stirring rod 13 is used to collect the waste salt material when it rotates. Together with the auger 12, it can turn the bottom waste salt material to the upper layer. Together with the side scraper 14 and the bottom scraper 15, it can simultaneously scrape and clean the inner wall and bottom surface of the furnace body 1.

[0021] Specifically, a drive motor 10 is fixedly installed at the top center of the furnace cover 8, and the end of the output shaft of the drive motor 10 is fixedly connected to the top of the transmission shaft 11.

[0022] Specifically, the top two sides of the furnace body 1 are fixedly installed with locking seats 7 by welding, and the bottom two sides of the furnace cover 8 are provided with locking rods 9. The furnace cover 8 is fixedly locked to the furnace body 1 by the locking rods 9 and locking seats 7.

[0023] Specifically, an observation port 2 is provided in the middle of one side of the furnace body 1, and a control panel 3 is installed below the side of the furnace body 1 with the observation port 2.

[0024] Specifically, a discharge port 4 is provided at the bottom of the other side of the furnace body 1, and a valve body 5 is installed inside the discharge port 4.

[0025] Specifically, an exhaust port 6 is provided at the top of the side of the furnace body 1 away from the discharge port 4. The exhaust port 6 extends into the interior of the furnace body 1 and communicates with its interior top.

[0026] In this embodiment, during use, after the waste salt material is added into the furnace body 1, the heating components inside the furnace body 1 are activated via the control panel 3 to heat the waste salt. Then, the drive motor 10 drives the transmission shaft 11 to rotate, causing the arc-shaped stirring rod 13 to rotate around the transmission shaft 11. Utilizing the arc-shaped structure of the arc-shaped stirring rod 13, the waste salt material gradually gathers in the middle of the transmission shaft 11 during rotation. Simultaneously, the rotation of the transmission shaft 11 also drives the auger 12 to rotate, which tumbles the gradually gathering waste salt material, causing the bottom layer material to surge to the top, thereby ensuring proper heating. The uniformity is achieved by simultaneously rotating the arc-shaped stirring rod 13, which drives the side scraper 14 to scrape the inner wall of the furnace body 1 to prevent waste salt from adhering. Furthermore, the bottom scraper 15, driven by the transmission shaft 11 and the arc-shaped stirring rod 13, scrapes the bottom surface of the furnace body 1 to prevent solid waste salt from adhering to its bottom. This design allows for the simultaneous stirring of waste salt material inside the furnace body 1, collection and tumbling of the waste salt material, and, in conjunction with the side scraper 14 and bottom scraper 15, scraping and cleaning to prevent waste salt material from adhering, greatly improving the efficiency and effectiveness of waste salt discharge.
