Description

Technical Field

[0001] The invention belongs to the technical field of titanium slag treatment, and in particular is a low-temperature acid leaching device for blast furnace titanium slag based on a water quenching process. Background Art

[0002] Blast furnace titanium slag is a high-grade titanium resource, usually coexisting with iron, silicon, aluminum, magnesium and other elements. Due to its complex mineral composition and physical and chemical properties, blast furnace titanium slag is difficult to use directly in traditional smelting processes and is often accumulated as solid waste, resulting in resource waste and environmental pollution.

[0003] The treatment and resource utilization of blast furnace titanium slag is a research hotspot in the field of metallurgy and materials science. The low-temperature acid leaching device for blast furnace titanium slag based on water quenching process is an industrial equipment specially used to treat blast furnace titanium slag. The working principle of the device is to quickly cool the blast furnace titanium slag through a water quenching process to fix its mineral phase and reduce thermal decomposition, and then use acid leaching under low temperature conditions to extract titanium and other valuable metals. The design goal is to achieve efficient resource utilization of blast furnace titanium slag, reduce environmental pollution, and at the same time improve metal recovery rate and economic benefits.

[0004] However, the existing low-temperature acid leaching equipment for blast furnace titanium slag based on the water quenching process cannot adjust the water vapor transfer rate in time during use, and cannot quickly control the cooling rate, resulting in inconsistent cooling effect of the blast furnace titanium slag, affecting the efficiency of subsequent acid leaching treatment and metal recovery rate. Summary of the invention

[0009] Furthermore, the water outlet is connected to a waste liquid treatment box via a connecting pipe, the steam outlet is connected to the waste liquid treatment box via a connecting pipe and an air pump is provided at the connection, and the waste liquid treatment box is connected to the water storage tank via a connecting pipe.

[0010] Description: The water vapor after water quenching flows out through the steam outlet to the waste liquid treatment box. At the same time, the waste liquid after water quenching flows out through the water outlet to the waste liquid treatment box. After being treated in the waste liquid treatment box, it is re-pumped into the water storage tank for recycling. It has the advantages of energy saving and emission reduction, conforms to the concept of green production, and is conducive to environmental protection.

[0011] Furthermore, the waste liquid treatment box includes a filter inner box and an insulated bottom box mounted on the outer wall of the bottom end of the filter inner box, a filter layer is arranged inside the filter inner box, a U-shaped condenser is arranged inside the insulated bottom box, a three-way pipe is connected to the side wall of the insulated bottom box, the other two ends of the three-way pipe are respectively connected to the water outlet and the steam outlet, an automatic opening and closing valve is arranged on the side wall of the filter inner box and at the lower end of the filter layer, a temperature sensor is arranged in the insulated bottom box, and a constant temperature heating plate is arranged on the inner wall of the insulated bottom box.

Compared with directly placing it in the acid leaching body, the titanium slag containing frame can effectively prevent the blast furnace titanium slag from being lost during the acid leaching process, reduce material loss, and improve resource utilization. After the acid leaching is completed, the blast furnace titanium slag and the titanium slag containing frame can be easily taken out as a whole, and the loading and unloading of the blast furnace titanium slag can be realized, and the operation is efficient and convenient.

The blast furnace titanium slag placed in each mesh containing frame is acid-leached by stirring, which can ensure that the acid liquid is in full contact with the blast furnace titanium slag, improve the uniformity of acid leaching, and improve the efficiency and effect of blast furnace titanium slag treatment.

[0021] Furthermore, a reinforcing support rod is provided at the bottom end of the guide plate.

[0022] Note: The bottom end of the guide plate is supported by reinforcing the support rod to improve the installation stability of the guide plate.

[0023] Furthermore, a liquid level sensor is provided in the overflow drainage box, and an exhaust port is provided on the side wall of the alkaline reagent box.

[0024] Description: The liquid level in the overflow drain tank is monitored in real time by the liquid level sensor, which facilitates the timely cleaning of the waste liquid after acid leaching.

[0026] Description: When the water vapor regulating unit is in use, under normal circumstances, each regulating blocking block will block the corresponding through-port, and the water vapor generated by the water quenching treatment will flow out through each buffer mesh plate. When the amount of water vapor generated increases and the temperature inside the water quenching body is too high, the regulating blocking block will be moved out from the corresponding through-port through the compression effect of the micro electric telescopic rod, so that the water vapor will flow out from each through-port and the buffer mesh plate at the same time, thereby increasing the outflow rate of water vapor and maintaining the temperature inside the water quenching body, effectively avoiding overheating during the water quenching process and ensuring the stability and consistency of the water quenching effect.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

At the same time, the upper end of the placement platform is set as an inclined structure, which helps the blast furnace titanium slag to flow out more smoothly after the water quenching process, reduces the need for manual cleaning, and improves the processing efficiency;

[0029] (2) During the acid leaching treatment, the titanium slag holding rack is lifted and moved as a whole by a hydraulic scissor frame, so that the entire titanium slag holding rack can be conveniently placed in the acid leaching body. The acid leaching liquid passes through the mesh holding frame to perform acid leaching on the blast furnace titanium slag. Compared with directly placing the slag in the acid leaching body, the titanium slag holding rack can effectively prevent the blast furnace titanium slag from being lost during the acid leaching process, thereby reducing material loss and improving resource utilization. After the acid leaching is completed, the blast furnace titanium slag and the titanium slag holding rack can be conveniently taken out as a whole, so that the blast furnace titanium slag can be loaded and unloaded, and the operation is efficient and convenient.

[0047] Example 2

[0048] This embodiment discloses a method for using a blast furnace titanium slag low-temperature acid leaching device based on a water quenching process according to embodiment 1, which specifically comprises the following steps:

[0049] S1, placing the blast furnace titanium slag to be treated on the upper end of the placement net 201 through the delivery port, pumping the water in the water storage tank 11 into the water quenching body 1 by means of pumping, and evenly spraying it on the blast furnace titanium slag for water quenching treatment, and the treated waste liquid falls into the water filter box 200 through the placement net 201, and the water vapor generated after the water quenching treatment is discharged through the water vapor regulating unit 21 and the steam outlet 10;

[0066] In step S1, the water vapor after water quenching flows out to the waste liquid treatment box 28 through the steam outlet 10, and at the same time, the waste liquid after water quenching flows out to the waste liquid treatment box 28 through the water outlet 202. The water vapor and waste liquid after water quenching flow into the thermal insulation bottom box 281 through the three-way pipe 284, and are condensed and cooled through the U-shaped condenser 283 to form a to-be-treated liquid. At the same time, the temperature of the to-be-treated liquid is detected by the temperature sensor 285 to ensure that the temperature of the to-be-treated liquid is 2-3°C higher than the water temperature required by the water quenching process. If the temperature is too high, the condensation temperature of the U-shaped condenser 283 is lowered. When the temperature is suitable, the to-be-treated liquid enters the filter inner box 280, is filtered through the filter layer 282, and is pumped back to the water storage tank 11 for recycling;

[0067] In step S1, when the blast furnace titanium slag is placed on the placing grid 201 for water quenching treatment, the placing grid 201 is vibrated up and down through the interaction force between the exciting electromagnet 205 and the corresponding armature 204. At this time, the spring rod 23 will also be compressed and restored synchronously, so that the blast furnace titanium slag on the placing grid 201 can be fully dispersed during the water quenching process.
