Description

[0002] The main steps of quartz sand purification process are: sand feeding, sand washing, and sand discharge. According to the current quartz sand purification process, it takes about 20 hours for the reactor to discharge 300 tons of sand, which is time-consuming and seriously affects the production efficiency. The main reason for the slow sand discharge speed of the reactor is that the quartz sand will have faults and hardening after the acid discharge process. The faults prevent water from forming fluids in the gaps between the sands, and the water penetration rate is very slow, which makes the quartz sand unable to flow. The quartz sand becomes hardened and cannot form a fluid in the tank body, so it cannot be discharged quickly, which requires a lot of time to discharge the sand, and it is also prone to danger.

Among them, the first main water inlet 111, the second main water inlet 112 and the third main water inlet 113 are arranged on one side of the reactor cover 1, and the fourth main water inlet 23 is arranged at the bottom of the reactor body 2. The first main water inlet 111 directly guides the water flow from the reactor cover 1 into the reactor body 2; the second main water inlet 112 is connected to the first extension pipe 1121, and when the water flow flows in from the second main water inlet 112, the water flow is guided into the interior of the reactor body 2 through the first extension pipe 1121; the third main water inlet 113 is connected to the second extension pipe 1131, and the second extension pipe 1131 is suspended 2 meters above the first side water inlet assembly 21. When the water flow flows in from the third main water inlet 113, the water flow is guided into the reactor body 2 through the second extension pipe 1131.

[0026] Specifically, the diameter of the first main water inlet 111 is set to 100mm, the diameters of the second main water inlet 112 and the third main water inlet 113 are both set to 150mm, the diameter of the fourth main water inlet 23 is set to 80mm, and the diameters of the first side water inlet assembly 21 and the second side water inlet assembly 22 can be set to 60-100mm, preferably 80mm.

At the same time, open some water inlets in the first side water inlet assembly 21 and the second side water inlet assembly 22 to perform auxiliary sand flushing.

When the recoil arc reaches a predetermined arc, open the second main water inlet 112 to perform backwashing and sand discharge. By using multiple water inlets in coordination, the effect of rapid sand discharge can be achieved.

[0028] In one embodiment, the bottom of the reactor body 2 is further provided with a first auxiliary sand discharge port 25 and a second auxiliary sand discharge port 26. In this embodiment, the first auxiliary sand discharge port 25 and the second auxiliary sand discharge port 26 are arranged opposite to each other at the bottom of the reactor body 2. When the main sand discharge port 24 cannot discharge sand quickly, the first auxiliary sand discharge port 25 and the second auxiliary sand discharge port 26 can be opened to perform auxiliary sand discharge, so as to ensure that the quartz sand in the reactor body 2 can be discharged in time and speed up the sand discharge.

[0029] In one embodiment, a circulation heating hole 28 is provided at the bottom of the side wall of the reactor body 2. In this embodiment, the circulation heating hole 28 is provided at the bottom of the reactor body 2 for connecting an external temperature controller and controlling the temperature inside the reactor body 2 by using the temperature controller.

[0030] In one embodiment, the top of the reactor cover 1 includes a first semicircular cover 11 and a second semicircular cover 12, an opening is provided between the first semicircular cover 11 and the second semicircular cover 12, and the first main water inlet 111, the second main water inlet 112 and the third main water inlet 113 are arranged side by side on the first semicircular cover 11. In this embodiment, the opening is a long strip opening, which is arranged in the middle of the reactor cover 1, and the first semicircular cover 11 is separated from the second semicircular cover 12, and the first main water inlet 111, the second main water inlet 112 and the third main water inlet 113 are arranged side by side at one end of the first semicircular cover 11 close to the opening.

[0031] In one embodiment, the second semicircular cover body 12 is provided with a maintenance hole 121, a sand inlet hole 122, and an acid inlet hole 123. In this embodiment, the maintenance hole 121 and the sand inlet hole 122 are arranged side by side at one end of the second semicircular cover body 12 close to the opening, the maintenance hole 121 corresponds to the first main water inlet 111, the sand inlet hole 122 corresponds to the second main water inlet 112, and the acid inlet hole 123 is arranged on the second semicircular cover body 12.

In this embodiment, the first extension pipe 1121 is bent outward, so that the water flows into the first extension pipe 1121 from the second main water inlet 112 and flushes the sand laterally to prevent uneven sand flushing from causing quartz sand to agglomerate and be unable to be discharged. The second extension pipe 1131 is arranged straight, and the water flows into the third main water inlet 113 and flushes the sand downward.

[0036] An embodiment of the present invention further provides a quartz sand reactor, comprising the sand discharge structure of the quartz sand reactor as described above.

At this time, the fourth main water inlet is opened for sand flushing, and the third side water inlet and the sixth side water inlet are opened for auxiliary sand flushing to ensure that the quartz sand is in a fluid state and can be discharged from the main sand discharge port. During the discharge of the quartz sand, when the height of the quartz sand drops to the position of the second extension pipe, the third main water inlet is opened for backwashing and sand discharge, and when the recoil arc is close to the bending arc of the first extension pipe, the second main water inlet is opened for backwashing and sand discharge, so that the quartz sand can be quickly discharged from the main sand discharge port.

[0041] A quartz sand sensor may be provided in the reactor body, and the quartz sand sensor may be an infrared sensor. When a fault or hardening phenomenon is sensed in the reactor body, an alarm is issued to remind the operator to open the first side water inlet, the second side water inlet, the fourth side water inlet and the fifth side water inlet for sand flushing to ensure that the sand discharge process proceeds smoothly. The first side water inlet, the second side water inlet, the fourth side water inlet and the fifth side water inlet may be connected to sand flushing pipes of different lengths and different bending directions to ensure that faults or hardening phenomena at different positions inside the reactor body can be handled in time.
