Problems solved by technology

[0006] 2. Generate acid mist and pollute the environment:
[0007] Hydrochloric acid is volatile, and the acid mist generated during unloading and transshipment is not easy to deal with, and even more harmful to human health;
[0008] 3. High water consumption for cleaning:
[0009] After soaking, some strong acids and salts penetrate into the quartz ore or potassium sodium ore. To release these strong acids and salts from the mine requires repeated soaking and cleaning, which not only consumes a lot of water, but also makes it difficult to discharge no waste water. ;
[0010] 4. The effect of yellow skin treatment is not good
[0011] The current quartz ore or potassium sodium ore is basically cold soaked in the strong acid soaking process, the treatment effect of the yellow skin is poor, and the whiteness is low
Although some production plants use thermal soaking and use steam as a heat source, it will cause a large amount of tail gas during soaking, which will increase the difficulty of tail gas treatment; the liquid level will rise during the soaking process, and the acid concentration will gradually decrease, which is unfavorable for the repeated use of acid. The removal effect of yellow skin is poor, and the amount of acid is large, which increases the difficulty of wastewater treatment
At the same time, it is necessary to add boilers and other equipment
[0012] 5. High operating costs
[0013] Due to improper workmanship and various equipment, the operating cost is high

Embodiment 1

[0043] The yellow bark processing equipment of quartz ore or potash sodite ore soaks and cleans the kettle, and its center pipe 16 is made of multi-section round pipes connected by straight joints 17 .

[0044] Use yellow skin treatment equipment of the present invention to soak, the step of cleaning of quartz ore is:

[0045] (1) Pull the first vibrating ring 14 and the second vibrating ring 15 to the top of the central tube 16 with a rope, and connect and install the multi-section circular tubes of the central tube 16 through the straight joint 17;

[0046] (2) Crushing the quartz ore to a particle size of 10mm to 20mm, the crushed quartz ore particles are input into the rotary kiln drying cylinder and heated in reverse with the hot air after heat exchange, and the quartz ore particles are heated to 150°C;

[0047] (3) Add the hydrochloric acid after soaking the quartz ore particles in the immersion cleaning kettle, and the hydrochloric acid concentration in this kettle is a...

Embodiment 2

[0054] Except that in the (2) step, the quartz ore particles are heated to 180°C, the hydrochloric acid in the kettle in the 3rd step regulates the mass concentration to be 24%, the liquid level of the (4) step hydrochloric acid is 250mm higher than the quartz ore particle top surface, (5) In the step, the cleaning wastewater is neutralized to pH=8 and then the ore particles are cleaned by the clear water after pressure filtration, until the pH of the cleaning water sampled from the first detection port 9 is 6.2 and the first detection port 9 Except that the ore particles above the same level are transferred to the unloading stage, all the other steps are the same as in Example 1.

Embodiment 3

[0056]Except that in the (2) step, the quartz ore particles are heated to 210°C, in the third step, the concentration of hydrochloric acid in the kettle is adjusted to be 26%, the liquid level of the (4) step hydrochloric acid is 300mm higher than the top surface of the quartz ore particles, (5) In the step, the cleaning waste water is neutralized to pH=9 and then the clear water after the press filter is used to clean the quartz ore grains, until the pH of the cleaning water of the cleaning water sampled from the first detection port 9 is 6.5 Except that the quartz ore particles above the same level as the first detection port 9 are transferred to the unloading stage, all the other steps are the same as in Embodiment 1.

[0057] In the applicant's experiment, a polypropylene pipe with a diameter of 500mm was used as the wall of the soaking and cleaning kettle, and a polypropylene pipe with a diameter of 110mm was used as the center pipe. figure 1 , 2 Make a Soaking Wash Kett...

Abstract

The invention discloses a yellow peel treatment process and yellow peel treatment equipment for quartz mine or alkalifeldspar mine. The yellow peel treatment process comprises the following steps: crushing the quartz mine or the alkalifeldspar mine into mineral particles with particle sizes of 10-20mm, feeding the mineral particles in a drying barrel of a rotary kiln and heating the mineral particles to 150-210 DEG C, then transferring the mineral particles into a soaking cleaning kettle and soaking the mineral particles with hydrochloric acid for 8 hours, then draining hydrochloric acid, transferring the quartz mineral particles or the alkalifeldspar mineral particles in a cleaning phase, and cleaning the mineral particles in a mist-spraying manner through clear water after neutralization pressure-filtration; and unloading while cleaning the mineral particles until the pH value of water is 6.0-6.5, and drying the obtained mineral particles through the drying barrel of the rotary kiln to obtain a finished product. According to the yellow peel treatment process and the yellow peel treatment equipment, which are disclosed by the invention, the quartz mine or the alkalifeldspar mine is soaked and cleaned through a kettle body integrating a soaking function and a cleaning function, heated by virtue of hot air, and soaked through adopting a mist-spraying cleaning method instead of a cleaning pool, thus equipment investment is reduced, repeated use of acid is benefited, cleaning water consumption is reduced, yellow peel removal efficiency is increased, and the yellow peel treatment process and the yellow peel treatment equipment are suitable for large-scale production.

Description

technical field [0001] The invention relates to a process and equipment for treating yellow skin of quartz ore or potassium sodium ore. [0002] technical background [0003] At present, the yellow skin treatment of quartz ore ore is basically that the quartz ore ore is soaked in hydrochloric acid after crushing, and the hydrochloric acid is drained after soaking, and the quartz ore ore is transported to the cleaning tank. Add water to soak and wash repeatedly, and dry the qualified quartz ore or potash sodite ore to obtain the product. There are following problems in this technique: [0004] 1. Large investment in equipment: [0005] This process requires the construction of a series of cleaning pools. Because the soaked quartz ore or potassium soda ore contains strong acid, it requires high acid resistance for transport and transportation equipment; [0006] 2. Generate acid mist and pollute the environment: [0007] Hydrochloric acid is volatile, and the acid mist gene...
