Description

Technical Field

[0001] This utility model relates to a chlorination equipment for quartz sand purification, belonging to the field of quartz sand purification technology. Background Technology

[0002] Quartz sand purification generally involves high-temperature heating, which causes impurities in the quartz sand to undergo physical or chemical changes at high temperatures, thereby separating them from the quartz.

[0003] There are various types of chlorination purification furnaces in the prior art, such as a three-stage chlorination purification furnace for high-purity quartz sand disclosed in CN119034645A, and a chlorination purification equipment and purification method for high-purity quartz sand disclosed in CN118698480A.

[0004] The technical solutions disclosed in the aforementioned patent documents still have the following technical problems, based on practical experience:

[0005] During the feeding process of the preheated quartz sand into the purification furnace, it is fed into the cold end of the furnace. The quartz sand comes into contact with chlorides generated by hydrogen chloride at the cold end. These chlorides (potassium, calcium, iron, copper, etc.) can contaminate the product and affect its quality. Air and impurities can also easily enter the furnace through the inlet and outlet, contaminating the product and affecting its quality.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] This invention addresses the shortcomings of the prior art by providing a quartz sand purification and chlorination equipment that enables high-temperature feeding, preventing air and impurities from entering the furnace through the inlet and outlet and contaminating the product, thus ensuring product quality.

[0008] To solve the above technical problems, the present invention adopts the following technical solution:

[0009] A quartz sand purification and chlorination equipment includes an inclined purification furnace body, a rotatable purification pipe running through the furnace body, a guide pipe that rotates synchronously with the feed end of the purification pipe, and a discharge end of the guide pipe located in the high-temperature section inside the purification furnace body. A feeding pipe is installed inside the feed end of the guide pipe, and a gas conduit a runs through the feeding pipe. A gas collecting guide hood is installed on the discharge end of the purification pipe, and a gas conduit b runs through the gas collecting guide hood.

[0010] Furthermore, the inner wall of the purification pipe is provided with a plurality of circumferentially distributed protrusions along its length.

[0011] Furthermore, the outer wall of the guide tube is provided with multiple protrusions distributed in a circular pattern. The protrusions and ridges are connected by a spline positioning method to realize the concentric synchronous transmission of the purification pipe and the guide tube.

[0012] Furthermore, the discharge end of the guide tube adopts a constricted structure, and the constricted structure has multiple evenly distributed round holes.

[0013] Furthermore, a feeding hopper is provided at the end of the feeding pipe away from the guide pipe.

[0014] Furthermore, a DC vibrator is installed at the bottom of the feeding pipe, and a feeding hole is provided at the discharge end of the feeding pipe.

[0015] Furthermore, a connecting sleeve is provided at the connection between the feeding pipe and the guide pipe.

[0016] Furthermore, an exhaust gas collection hood is installed on the outside of the discharge end of the feeding pipe, and the exhaust gas collection hood is fastened to the inlet end of the purification pipe.

[0017] Furthermore, the gas conduit b is fixedly connected to the gas collection guide hood via a Morse taper fixing member.

[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0019] In this invention, the feeding pipe is connected to the guide pipe at its end. The guide pipe and the purification pipe are positioned by a spline to achieve concentric synchronous transmission. The equipment can continuously feed materials by means of the rotating spiral principle through its own tilt angle. The discharge port of the guide pipe is set in the high-temperature section inside the purification furnace to achieve feeding in the high-temperature section. This isolates the product from the chloride generated by hydrogen chloride at the cold end, preventing chlorides (potassium, calcium, iron, copper, etc.) from contaminating the product and ensuring product quality.

[0020] This invention uses gas protection devices installed at the inlet and outlet of the purification pipeline to replace the air inside the pipeline with nitrogen saturation, thereby controlling and preventing air and impurities from contaminating the product and ensuring product quality.

Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown in the figure, this utility model provides a quartz sand purification and chlorination equipment, including a purification furnace body 1 arranged at an inclination, a rotatable purification pipe 2 passing through the purification furnace body 1, a guide pipe 3 that rotates synchronously with the feed end of the purification pipe 2, the discharge end of the guide pipe 3 being located in the high-temperature section inside the purification furnace body 1, and a feeding pipe 5 being installed in the feed end of the guide pipe 3.

[0029] The inner wall of the purification pipe 2 is provided with a plurality of circumferentially distributed protrusions 201 along its length. The protrusions 201 can not only fully homogenize the product in the pipe, but also improve the strength of the pipe body.

[0030] The outer wall of the guide pipe 3 is provided with a plurality of protrusions 301 distributed in a circular pattern. The protrusions 301 and the convex ridges 201 are connected by a spline positioning method to realize the concentric synchronous transmission of the purification pipe 2 and the guide pipe 3. The guide pipe 3 is continuously fed by utilizing its own tilt angle and the principle of rotating spiral.

[0031] The discharge end of the guide pipe 3 adopts a constricted structure with multiple evenly distributed circular holes 302. The material in the guide pipe 3 enters the purification pipe 2 through the circular holes 302. The constricted structure can reduce nitrogen spillage, improve feeding efficiency, avoid backflow, and improve the overall yield.

[0032] The feeding pipe 5 is equipped with a feeding hopper 7 at the end away from the guide pipe 3, and a gas conduit a8 is installed inside the feeding pipe 5. The gas conduit a8 is used to protect the input of nitrogen gas and prevent air and impurities from contaminating the product during the feeding process.

[0033] A DC vibrator is installed at the bottom of the feeding pipe 5, and a feeding hole 501 is provided at the discharge end of the feeding pipe 5. The DC vibrator provides power for feeding, so that the material enters the guide pipe 3 evenly and slowly through the feeding hole 501.

[0034] A connecting sleeve 6 is provided at the connection between the feeding pipe 5 and the guide pipe 3.

[0035] An exhaust gas collection hood 4 is installed on the outside of the discharge end of the feeding pipe 5, and the exhaust gas collection hood 4 is fastened to the inlet end of the purification pipe 2. The exhaust gas collection hood 4 is used to collect the chlorine gas generated in the reaction inside the purification pipe 2, and after the exhaust gas is treated and meets the emission standards, it is discharged.

[0036] A gas collecting guide hood 9 is installed at the outlet end of the purification pipeline 2. A gas conduit b11 is installed inside the gas collecting guide hood 9. The gas conduit b11 is fixedly connected to the gas collecting guide hood 9 through a Morse taper fixing member 10. The gas conduit b11 is used for the input of nitrogen and hydrogen chloride gas.

[0037] The specific working principle of this utility model is as follows:

[0038] In this invention, the feeding pipe 5 is connected to the guide pipe 3 at its end. The guide pipe 3 and the purification pipe 2 are positioned by a spline to achieve concentric synchronous transmission. The guide pipe 3 can continuously feed material by utilizing its own tilt angle and the principle of rotating spiral. The outlet of the guide pipe 3 is located in the high-temperature section inside the purification furnace, enabling feeding in the high-temperature section. This isolates the product from contact with chlorides generated by hydrogen chloride at the cold end, preventing secondary contamination of the product by chlorides (potassium, calcium, iron, copper, etc.) and ensuring product quality.

[0039] This invention uses a gas protection device installed at the inlet and outlet of the purification pipeline 2 to replace the air in the pipeline with nitrogen saturation, thereby controlling and preventing secondary pollution of the product by air and introduced impurities.
