Description

Technical Field

[0001] This utility model relates to the field of quartz sand processing technology, and in particular to a quartz sand calcination machine. Background Technology

[0002] In the calcination process of quartz sand processing, feed dust and calcination flue gas are significant environmental and technological issues. Feed dust mainly originates from fine particles of the quartz sand raw material, which are released during feeding due to mechanical vibration, airflow disturbance, and other factors. This not only harms the health of operators and the operation of equipment but also pollutes the environment. The flue gas generated during calcination contains pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants mainly originate from fuel combustion and the chemical reactions of impurities in the quartz sand. If emitted directly without treatment, they will cause serious air pollution. Therefore, how to effectively control feed dust and treat calcination flue gas is a technical challenge that urgently needs to be solved in the quartz sand processing industry.

[0003] A calcination processing device for purifying quartz sand, disclosed in CN220223612U, includes a calcination box, a discharge pipe, and a gas outlet pipe. The discharge pipe and the gas outlet pipe are respectively connected to the front and one side of the calcination box. A stirring mechanism is installed inside the calcination box, and a filtration mechanism is installed on the top of the calcination box. The filtration mechanism includes a connecting pipe, an automatic valve, a filter box, a fixed frame, and a filter screen. In this calcination processing device for purifying quartz sand, quartz sand particles fall onto the filter screen, which filters out large pieces of quartz sand, allowing smaller pieces of quartz sand to enter the calcination box for calcination processing. This allows for rapid and efficient purification of quartz sand, improving its quality.

[0004] The aforementioned equipment can only filter quartz sand, and the dust generated during the process and the smoke generated during calcination cannot be effectively treated, resulting in poor practicality. Therefore, a new type of quartz sand processing and calcining machine is provided to solve the above problems. Utility Model Content

[0021] Furthermore, air outlets 9 and air inlet pipes 10, which communicate with the interior, are respectively connected to the outer walls of the feed box 7 on both sides. The air inlet pipe 10 is used to connect to an external fan, and the air outlets 9 are used to connect to a bag filter. A discharge box 13 is connected to the discharge port of the calcining cylinder 2, which can screen the quartz sand when it is fed through the feed box 7, ensuring the quality and efficiency of quartz sand calcination. At the same time, the airflow and negative pressure are used to blow the dust during the feeding of quartz sand through the air outlets 9 to the connected bag filter for collection, reducing the interference of dust on the surrounding environment and calcination quality. The discharge box 13 is a hollow structure with openings at the top and bottom. An opening is provided on the surface of the frame 1 directly below the discharge box 13. The discharge box 13 is located inside the opening on the frame 1, and its bottom opening extends into the bottom of the frame 1. The top opening of the discharge box 13 is also present. An air filter 14 connected to the interior of the calcining cylinder 2 is provided. The rotating mechanism 4 includes a servo geared motor 41, a rotating gear 42, and a driven gear ring 43. The driven gear ring 43, which is aligned with the axis of the calcining cylinder 2, is installed on the outer wall of the calcining cylinder 2.
