DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] In order to solve the technical problem that quartz sand cannot be continuously purified by chlorination in the prior art, the present invention provides a quartz high-temperature chlorination device capable of continuously chlorinating and purifying quartz sand.

[0021] It should be noted that the quartz high-temperature chlorination device described in the present invention is used for but not limited to chlorination purification of quartz sand. For the convenience of explanation, in the present invention, only the application of the quartz high-temperature chlorination device to chlorination purification of quartz sand is used as an example for explanation, and the principle of applying the quartz high-temperature chlorination device to other types of equipment is essentially the same as the principle applied to chlorination purification of quartz sand, which will not be repeated here.

[0022] See also Figure 1 , Figure 1The present invention is a schematic structural diagram of a quartz high-temperature chlorination device in an embodiment of the present invention. The quartz high-temperature chlorination device includes a quartz high-temperature chlorination device, including a preheating mechanism 1, two heat preservation mechanisms 2 and a chlorination mechanism 3. The preheating mechanism 1 is used to continuously preheat the material; the feed ends of the two heat preservation mechanisms 2 can be selectively connected to the discharge end of the preheating mechanism 1 for storing the preheated material; the feed end of the chlorination mechanism 3 can be selectively connected to the discharge end of any one of the two heat preservation mechanisms 2 for chlorinating the material output by the heat preservation mechanism 2 at a preset temperature; when the feed end of the chlorination mechanism 3 is connected to the discharge end of one heat preservation mechanism 2, the communication channel between the feed end of the heat preservation mechanism 2 and the discharge end of the preheating mechanism 1 is closed, and the feed end of the other heat preservation mechanism 2 is connected to the discharge end of the preheating mechanism 1.

[0023] The quartz sand first enters the preheating mechanism 1, which is responsible for continuously preheating the quartz sand to ensure that the quartz sand reaches the initial temperature required for high-temperature chlorination; the preheated quartz sand enters the insulation mechanism 2, which insulates the preheated quartz sand, and the feed end of the chlorination mechanism 3 is selectively connected to any one of the discharge ends of the two insulation mechanisms 2, and the chlorination mechanism 3 chlorinates the quartz sand input by the insulation mechanism 2; when the chlorination mechanism 3 is connected to the discharge end of a certain insulation mechanism 2 for chlorination, the channel between the feed end connected to the insulation mechanism 2 and the preheating mechanism 1 is closed. At this time, the chlorination gas used in the chlorination process of the chlorination mechanism 3 will not enter the preheating mechanism 1 through the chlorination mechanism 3, and, during the unloading process of the insulation mechanism 2, the preheating mechanism 1 can continue The preheated quartz sand is fed into another heat preservation mechanism 2. When the quartz sand in the heat preservation mechanism 2 is exhausted, the heat preservation mechanism 2 is switched so that the communication channel between the heat preservation mechanism 2 and the chlorination mechanism 3 is closed, and the communication channel with the discharge end of the preheating mechanism 1 is connected. The communication channel between the feed end of the other heat preservation mechanism 2 and the discharge end of the preheating mechanism 1 is closed, and the communication channel with the feed end of the chlorination mechanism 3 is connected. Thus, continuous chlorination treatment of the quartz sand can be achieved. Moreover, during the treatment process, no chlorination gas will leak outward through the heat preservation mechanism 2, thereby avoiding the risk of leakage of chlorination gas. Moreover, in the present application, heating and high-temperature chlorination are divided into two links. In both links, a large amount of quartz sand can be treated quickly, which can speed up the high-temperature chlorination treatment of the quartz sand.

[0024] It should be understood that the preheating mechanism 1 can be a continuous heating furnace, a tunnel heating furnace, etc. The heat preservation mechanism 2 can be a heat preservation tank, a heat preservation box, a heat preservation barrel, etc. The chlorination mechanism 3 can be various equipments capable of high-temperature chlorination of quartz sand.

[0025] like Figure 1As shown, in one embodiment, the quartz high-temperature chlorination device also includes two discharging mechanisms 4, the feed ends of the two discharging mechanisms 4 can be selectively connected to the discharging end of the chlorination mechanism 3, and when the feed end of one discharging mechanism 4 is connected to the discharging end of the chlorination mechanism 3, the connecting passage between the feed end of the other discharging mechanism 4 and the chlorination mechanism 3 is closed; when the discharging mechanism 4 is feeding, the discharging end of the discharging mechanism 4 is closed.

[0026] Specifically, after the chlorination is completed, the discharge end of the chlorination mechanism 3 can be selectively connected to any one of the two discharge mechanisms 4. At this time, the feed end connected to the discharge mechanism 4 is opened, and the discharge end is closed. At this time, the quartz sand enters the discharge mechanism 4, and the chlorination gas cannot directly leak outward through the discharge mechanism 4. When the quartz sand contained in the discharge mechanism 4 reaches a preset amount, the discharge mechanism 4 is switched so that the other discharge mechanism 4 is connected to the discharge channel of the chlorination mechanism 3.

[0027] By setting up two discharging mechanisms 4, one of the two discharging mechanisms 4 is used for feeding and the other for discharging, the quartz sand produced by continuous chlorination can be continuously discharged into the discharging mechanism 4 and continuously discharged through the discharging mechanism 4. Moreover, when the quartz sand enters the discharging mechanism 4 through the chlorination mechanism 3, no leakage of chlorination will occur.

[0028] It should be understood that the discharging mechanism 4 can be a discharging bin, a discharging barrel, a discharging tank, etc.

[0029] like Figure 3 As shown, in one embodiment, the chlorination mechanism 3 includes a quartz sleeve 31, a feed pipe 32, a discharge pipe 33 and a quartz tube 34. The feed pipe 32 and the discharge pipe 33 are connected to the quartz sleeve 31 and are respectively located at the two ends of the quartz sleeve 31. The feed pipe 32 can selectively connect to any one of the two insulation mechanisms 2, and the discharge pipe 33 can selectively connect to any one of the two discharge mechanisms 4. The peripheral wall of the quartz sleeve 31 is provided with an exhaust hole; the quartz tube 34 can be rotatably built into the quartz sleeve 31, and the outer wall of the quartz tube 34 is provided with a gas supply hole 34a connected to the interior.

[0030] The material enters the quartz sleeve 31 through the feed pipe 32, and undergoes a chlorination reaction in the quartz tube 34. After the reaction is completed, the material is discharged through the discharge pipe 33; the outer wall of the quartz tube 34 is provided with a gas supply hole 34a for supplying chlorine or other chlorinating agents into the quartz tube 34, and since the gas supply hole 34a is provided on the quartz tube 34, a plurality of gas supply channels can be provided on the quartz tube 34, or a strip-shaped gas supply hole 34a can be provided, so that the position of the chlorine gas inlet quartz sleeve 31 can be distributed along the length direction of the quartz sleeve 31, so that the chlorine gas enters more evenly, avoiding the problem of uneven chlorine gas distribution caused by single gas intake and single gas exhaust; at the same time, the peripheral wall of the quartz sleeve 31 is provided with an exhaust hole for discharging waste gas generated during the reaction; by providing the quartz sleeve 31 and the quartz tube 34, the quartz tube 34 can withstand the corrosion of chlorine.

[0031] like Figure 6 As shown, in one embodiment, the inner diameter of the gas supply hole 34 a gradually decreases along the direction approaching the outer wall of the quartz tube 34 .

[0032] Through the above arrangement, when the chlorinated gas approaches the outlet end of the gas supply hole 34a, the gas pressure gradually increases, which can increase the pressure of the chlorinated gas contacting the quartz sand, and facilitate the full mixing of the quartz sand and the chlorinated gas. Secondly, after the pressure increases, it can prevent the quartz sand from contacting or approaching the outlet of the gas supply hole 34a; moreover, since the inner diameter of the gas supply hole 34a gradually decreases in the direction close to the outer wall of the quartz tube 34, the size of the outlet of the gas supply hole 34a is relatively small, and it is not easy to be blocked by relatively large particles of quartz sand.

[0033] like Figure 2 and Figure 3 As shown, in one embodiment, the chlorination mechanism 3 further includes a driving member 35, and the driving member 35 is connected to the quartz tube 34, and is used to drive the quartz tube 34 to rotate around its own axis.

[0034] It should be understood that the driving member 35 can be a belt transmission mechanism, a gear transmission mechanism, a chain transmission mechanism, etc. driven by a motor.

[0035] By setting the driving member 35, the driving member 35 can drive the quartz tube 34 to rotate. During the rotation of the quartz tube 34, the position of the gas supply hole 34a changes, which can change the position where the chlorine gas enters the quartz sleeve 31, so that the chlorine gas and the quartz sand can be mixed more evenly.

[0036] It should be understood that the quartz sand can move along the axial direction of the quartz sleeve 31 under the action of gravity, or can move along the axial direction of the quartz sleeve 31 under the drive of external force, such as Figure 3As shown, in one embodiment, the chlorination mechanism 3 further includes a spiral driving portion 36 , which is connected to the quartz tube 34 and is used to rotate driven by the rotating quartz tube 34 to drive the material to move along the axial direction of the quartz sleeve 31 .

[0037] Specifically, when the driving member 35 drives the quartz tube 34 to rotate, the quartz tube 34 drives the spiral driving part 36 to rotate. The rotating spiral driving part 36 can stir the quartz sand in the quartz sleeve 31, so that the quartz sand and the chlorine are evenly mixed and released, and the rotating spiral driving part 36 can also push the quartz sand to move along the axial direction of the quartz sleeve 31, so that the quartz sand moves from the feeding end to the discharging end of the quartz sleeve 31.

[0038] In the process of chlorination of quartz sand, waste gas will be generated. There may be some unreacted chlorine in the waste gas. In order to avoid the waste gas endangering human safety and environmental safety, such as Figure 1 and Figure 3 As shown, in one embodiment, the chlorination mechanism 3 also includes a shell 37; the quartz sleeve 31 is built into the shell 37; the quartz high-temperature chlorination device also includes a negative pressure exhaust mechanism 5, and the air inlet end of the negative pressure exhaust mechanism 5 is connected to the shell 37.

[0039] By setting up the shell 37, the waste gas formed by high-temperature chlorination in the quartz sleeve 31 is discharged into the shell 37 through the exhaust hole. The shell 37 can collect and gather the waste gas formed by high-temperature chlorination. Driven by the negative pressure exhaust mechanism 5, the waste gas is discharged to a preset location for treatment, thereby preventing the waste gas from harming the environment and human safety.

[0040] It should be understood that the negative pressure exhaust mechanism 5 can be a vacuum pump, a negative pressure fan, etc.

[0041] During the rotation of the quartz tube 34, the quartz sand in the quartz sleeve 31 will be stirred, which may cause the quartz sand to flow out from the exhaust hole. Figure 6 As shown, in one embodiment, the chlorination mechanism 3 further includes an interception net 3a, which is arranged relative to the exhaust hole and connected to the quartz tube 34. The interception net 3a is used to intercept the material entering the exhaust hole.

[0042] By providing the interception net 3a at the exhaust hole, the quartz sand in the quartz sleeve 31 can be prevented from flowing out of the exhaust hole, and the interception net 3a will not hinder the exhaust gas from being discharged.

[0043] In the process of high temperature chlorination of quartz sand, in order to maintain the quartz sand at a preset temperature, for this purpose, Figure 3 and Figure 6 As shown, in one embodiment, the chlorination mechanism 3 further includes a heating element 38 , and the heating element 38 is connected to the quartz sleeve 31 for heating the material in the quartz sleeve 31 .

[0044] The heating element 38 can be provided to heat the quartz sand during the chlorination process and maintain the quartz sand at a set temperature.

[0045] It should be understood that the heating element 38 may be an electric heating wire, which may be arranged around the quartz sleeve 31 , or the heating element 38 may be a gas heating device, etc.

[0046] Since the quartz tube 34 rotates along its own axis under the direction of the driving member 35, in order to inject chlorine into the rotating quartz tube 34, in one embodiment, the chlorination mechanism 3 also includes an air inlet member 39, and the air inlet member 39 includes an air inlet pipe 391. The air inlet pipe 391 can be rotatably connected to the quartz tube 34 and is sealed to the quartz tube 34.

[0047] When chlorine needs to be injected into the quartz tube 34, the chlorine enters the quartz tube 34 through the air inlet pipe 391, and then enters the quartz sleeve 31 through the quartz tube 34. Since the air inlet pipe 391 is rotatably connected to the quartz tube 34, the air inlet pipe 391 can be relatively fixed when the quartz tube 34 rotates. Moreover, since the air inlet pipe 391 is sealed to the quartz tube 34, it is possible to prevent chlorine from flowing out through a possible gap between the air inlet pipe 391 and the quartz tube 34.

[0048] When the quartz sand after high temperature chlorination treatment enters the discharging mechanism 4, part of the waste gas may enter the discharging device. In order to avoid the harm of this part of waste gas to the environment and human safety, Figure 1 As shown, in one embodiment, the air inlet end of the negative pressure exhaust mechanism 5 can be selectively connected to the two discharge mechanisms 4. When the feed end of the discharge mechanism 4 is connected to the discharge end of the chlorination mechanism 3, the communication channel between the discharge mechanism 4 and the negative pressure exhaust mechanism 5 is closed.

[0049] When the quartz sand that has been treated at high temperature enters the discharging mechanism 4, the negative pressure exhaust mechanism 5 will exhaust the gas in the discharging mechanism 4, and can extract the waste gas in the discharging mechanism 4. Moreover, during the feeding process of the discharging mechanism 4, the connecting channel between the discharging mechanism 4 and the negative pressure exhaust mechanism 5 is closed, which can prevent the falling quartz sand from entering the connecting channel and prevent the flowing quartz sand from clogging the channel.

[0050] like Figure 4 , 5, 7, in one embodiment, the housing 37 includes a shell 372, a bracket 371, and a first sealing ring 373. The bracket 371, the quartz sleeve 31, and the heating element 38 are built in the shell 372. The quartz sleeve 31 is connected to the bracket 371. The interior of the quartz tube 34 is hollow and one end is open. The open end of the quartz tube 34 is built in the shell 372, and the closed end can rotate through the shell 372. The driving member 35 is arranged outside the shell 372 and connected to the quartz tube 34; the first sealing ring 373 is connected to the shell 372 and is arranged at the place where the quartz tube 34 passes through the shell 372. The first sealing ring 373 is sealed. The air inlet member 391 is sealed to fit the quartz tube 34; one end of the air inlet tube 391 is inserted into the open end of the quartz tube 34, and the other end can be rotated to pass through the outer shell 372; the air inlet member 39 also includes two bearings 392, a second sealing ring 393 and a third sealing ring 394. The two bearings 392 are embedded in the open end of the quartz tube 34 and are arranged between the quartz tube 34 and the air inlet tube 391. The second sealing ring 393 is connected to the quartz tube 34, and the sealing sleeve is arranged on the air inlet tube 391. The third sealing ring 394 is connected to the outer shell 372 and is arranged at the place where the air inlet tube 391 passes through the outer shell 372. The third sealing ring 394 is sealed to fit the air inlet tube 391.

[0051] By providing the outer shell 372, the bracket 371, and the first sealing ring 373, the quartz tube 34, the connection point between the air inlet pipe 391 and the quartz tube 34 are all confined within the outer shell 372, and the air inlet pipe 391 and the quartz tube 34 passing through the outer shell 372 are sealed by the third sealing ring 394 and the first sealing ring 373, so that the possible leakage positions can be confined within the outer shell 372 to avoid leakage of chlorinated gas; secondly, by providing two bearings 392, the air inlet pipe 391 needs to rotate with the quartz tube 34 while being connected to the quartz tube 34, and by providing the second sealing ring 393, the second sealing ring 393 can seal the connection point between the air inlet pipe 391 and the quartz tube 34 to avoid leakage of chlorinated gas from the connection point between the air inlet pipe 391 and the quartz tube 34, so that the chlorinated gas can only flow out after reacting with the quartz sand.

[0052] like Figure 1 As shown, in one of the embodiments, the air inlet end of the negative pressure exhaust mechanism 5 can be selectively connected to the two insulation mechanisms 2. After all the quartz sand in the insulation mechanism 2 enters the chlorination mechanism 3, the feed end and the discharge end of the insulation mechanism 2 are closed, and the gas in the insulation mechanism 2 is extracted through the negative pressure exhaust mechanism 5 to prevent the exhaust gas from being discharged outward through the insulation mechanism 2.

[0053] It should be understood that in the present invention, the closing, sealing, opening and connecting of pipelines are all achieved by switching valves, and the valves can be manual valves or solenoid valves.

[0054] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention.
