Description

Technical Field

[0001] This utility model belongs to the field of yellow phosphorus slag water granulation technology, and specifically relates to a fully automatic cleaning type yellow phosphorus slag water granulator. Background Technology

[0002] Currently, steel slag is a complex substance formed by various chemical reactions and slag-forming materials during the steelmaking process. In order to reduce waste, lower costs, and avoid pollution of the environment by steel slag, it is necessary to granulate hydraulic steel slag for reuse.

[0003] The yellow phosphorus slag water also needs to be treated. In combination with existing technology, it is generally treated by air quenching through a combination of air and water. This includes controlling and reducing the production of rock wool by adjusting the pressure and flow rate of water and compressed air, thereby improving the economic benefits of granulated phosphorus slag.

[0004] A search for steel slag granulation technology revealed an existing technology announcement (CN219972343U) for a liquid steel slag air-quenching granulation device. This device, through the coordinated use of an exhaust pipe, air vent, and outlet pipe, utilizes the airflow from the quenching chamber to enhance the separation of steel slag and liquid water. Furthermore, the coordinated use of a shroud, angled nozzles, and a diversion pipe allows for the diversion of some liquid water during the quenching process, which is then sprayed obliquely upwards from the bottom of the quenching chamber. This helps to minimize the inadequate cooling of steel slag that has not been thrown a sufficient distance. This solution employs… The method involves separate water and air jetting for air quenching and granulation. However, if this method is applied to the air quenching treatment of yellow phosphorus slag water, it is difficult to control the mixing of water and air, resulting in poor granulation formation. This is because the water and air are jetted separately from different directions, leading to different contact sequences with the steel slag and thus different effects. Furthermore, if the water and air pressures are not properly adjusted or the water and air cannot be fully mixed during the treatment of yellow phosphorus slag water, the air quenching process will cause the product to be predominantly either rock wool or granulated beads, failing to produce the desired product.

[0005] Further research revealed that a converter steel slag granulation treatment device with the existing technology announcement number CN216738401U uses high-pressure air nozzles to quench and granulate the steel slag. The steel slag is atomized into glassy particles and falls onto the baffle. The actuator motor drives the first gear to rotate, which in turn drives the actuator screw to rotate, causing the sliding sleeve to move. This, in turn, moves the closed baffle, changing the distance between the two closed baffles, thereby controlling the steel slag outflow speed for subsequent screening.

[0006] Firstly, the granulation process not only focuses on dispersing the slag and water, but also depends on the degree of granulation achieved by rapid cooling. However, this solution uses separate high-pressure air to quench the steel slag. Using high-pressure air alone will cause the air to be heated by the processing box after the steel slag has been heated during the subsequent continuous air intake process, which will reduce the cooling effect during air quenching. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully automatic cleaning-type yellow phosphorus slag water granulator. It can introduce cooling water and high-pressure gas into the tank through the water inlet pipe and the main air inlet pipe, and spray them out after mixing at the nozzle. It can not only impact the yellow phosphorus slag water through the combined water and gas, but also cool it by wrapping it with cooling water, thus promoting the granulation effect. Furthermore, it can also allow high-pressure gas to enter the water tank and water pipes through the auxiliary air inlet pipe for impact descaling, and allow the cooling water to flow smoothly.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An automatic cleaning-type yellow phosphorus slag granulator includes a housing, a main air inlet pipe, and a water inlet pipe. The housing is divided into a water tank and a high-pressure chamber by a partition. A nozzle is located on one side of the high-pressure chamber. One end of the main air inlet pipe is connected to the high-pressure chamber. A branch pipe is attached to the water inlet pipe and connected to the water tank. A water pipe is located inside the housing, with one end connected to the water tank and the other end connected to the high-pressure chamber and located inside the nozzle. One end of the water pipe is fitted into the nozzle. A secondary air inlet pipe is attached to the main air inlet pipe and connected to the water inlet pipe. Switches are installed on both the water inlet pipe and the secondary air inlet pipe to control their opening and closing.

[0010] The high-pressure chamber is equipped with a guide plate that can guide the high-pressure gas to be discharged quickly and directly through the nozzle.

[0011] The water tank has openable and closable drain ports on both sides for quick removal of scale.

[0012] The nozzle end is threaded and fixed to the side wall of the housing via a threaded connection.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] Based on existing technology and using an external PLC control system, high-pressure water-air mixed injection is achieved. During the air-quenching and granulation of yellow phosphorus slag, the pressure and flow rate of water and compressed air are adjusted to control and reduce rock wool production, thereby improving the economic efficiency of granulated phosphorus slag. The injection process mainly involves introducing high-pressure gas through the main air inlet pipe and ejecting it through nozzles. Then, cooling water is introduced through the water inlet pipe and ejected through the nozzles. The cooling water and high-pressure gas mix at the nozzles to form a gas-water mixture, impacting the yellow phosphorus slag water. Under the combined effects of water cooling and gas atomization impact, the granulation process of the yellow phosphorus slag water is achieved. In the process, the yellow phosphorus slag is dispersed and cooled by rapid gas impact, and then the cooling process is accelerated by atomized cooling water, which improves the granulation effect. Furthermore, when there is a lot of scale in the water tank and water pipes, the water inlet pipe is closed and the auxiliary air inlet pipe is opened to allow high-pressure gas to enter the water tank along the auxiliary air inlet pipe to impact the inner wall of the water tank and water pipes and blow off the scale, realizing an automated cleaning function. This avoids damage to the granulator caused by steel slag and water quality, greatly improves the air quenching effect of the granulator and reduces the risk of nozzle blockage by scale, thereby ensuring the smooth flow of cooling water.

[0015] Furthermore, compared to the second prior art document in the background section, in this solution, the high-pressure gas and cooling water are transported independently, which can ensure the temperature and impact force of the cooling water and the high-pressure gas itself, which is beneficial for rapid granulation.
