Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of quartz sand processing, and relates to a leakage prevention device for a quartz sand purification furnace. Background Art
[0002] Quartz sand is a common and widely used non-metallic mineral raw material in nature. Ordinary quartz sand is mainly used in traditional fields with low requirements for quartz sand purity, such as glass products, building materials, ceramic products, mechanical casting, cement products, refractory materials, etc. Its preparation is simple, and only screening and separating impurities from the original ore or using a simple ore dressing process can meet the requirements. Most of the quartz sand produced in China is applied in these fields. High-purity quartz sand refers to quartz sand with a SiO₂ content greater than 99.995% and a total impurity element content less than 50×10⁻⁶.
[0003] Among the existing quartz sand purification methods, thermal chlorination can effectively purify quartz sand, and the overall level of the total impurity element content less than 50×10⁻⁶ can be achieved. However, for the existing purification equipment, it is impossible to avoid the leakage of gases such as HCl, Cl₂, and NH₄Cl during the production process.
[0004] The feeding end of the existing horizontal quartz sand purification furnace equipment is as Figure 1 shown. The feeding pipe extends into the inner part of the feeding end of the purification pipe. There is a simple exhaust device at the port, and there is no harmful gas leakage prevention device. Harmful gas leakage is likely to occur at the quartz sand feeding port and the discharging port, threatening the safety of personnel, environmental protection, and equipment. Summary of the Utility Model
[0005] The purpose of the present utility model is to address the above problems existing in the prior art and propose a leakage prevention device for a quartz sand purification furnace.
[0006] The purpose of the present utility model can be achieved by the following technical solutions: A leakage prevention device for a quartz sand purification furnace includes a purification pipe. One end of the purification pipe is connected with an exhaust hood, and the connection between the purification pipe and the exhaust hood is sealed. The exhaust hood is provided with a feeding pipe. The feeding pipe includes a vertical part and an extension part. The extension part extends into the purification pipe, and the diameter of the extension part decreases towards the side of the purification pipe. The tail of the extension part is arranged in a semi-open shape.
[0007] In the above-mentioned leakage prevention device for a quartz sand purification furnace, the exhaust hood is further provided with an air outlet pipe, and the bottom of the air outlet pipe is in a flared shape.
[0008] In the above-mentioned leakage prevention device for a quartz sand purification furnace, the connection between the feeding pipe hole and the exhaust hood is adhesively connected with a high-temperature adhesive.
[0009] In the above anti-leakage device for a quartz sand purification furnace, the air outlet pipe and the exhaust hood are connected by a ground joint.
[0010] In the above anti-leakage device for a quartz sand purification furnace, the exhaust hood is a double-layer quartz glass hood.
[0011] Compared with the prior art, the utility model is provided with a feed pipe hole, an air extraction hole, and a purification pipe hole on the exhaust hood, which are respectively connected to a feed pipe, an air outlet pipe, and a purification pipe; among them, the feed pipe hole is adhesively connected with high-temperature glue, the air outlet pipe is connected by a ground joint, and the purification pipe is connected by a flexible connection. Each connection is well sealed, and the gas coming out of the purification pipe is extracted from the air outlet pipe at the top for tail gas treatment to prevent the leakage of harmful gases; at the same time, the feed pipe is designed in a conical shape, which hinders the gas from escaping from the feed pipe when there is quartz sand in the pipe, and the tail of the feed pipe is designed to be semi-open to prevent the blockage of quartz sand.
