[0002] Quartz square crucible, also known as quartz glass ceramics, is a high-temperature non-stick stone mainly composed of silicon dioxide. It is widely used in many fields due to its non-toxic, odorless and corrosion-resistant characteristics. For example, in the metallurgical industry, quartz crucibles can be used for metal smelting and alloy preparation to ensure stability and safety during the smelting process. In the ceramic industry, quartz crucibles can be used for high-temperature firing of ceramic products to improve product quality and performance. In the electronics industry, quartz crucibles can be used to prepare semiconductor materials and electronic components.

[0003] However, when producing quartz crucibles, it is necessary to mix pretreated quartz sand with auxiliary materials such as clay, feldspar, boric acid, etc. in a certain proportion, add water to make slurry, and then pour the slurry into a square mold, and form a square quartz crucible green body through a drying and curing process. However, since there is no cooling device in the existing reactor, when various raw materials such as quartz sand are placed in the reactor for mixing and stirring, the stirring blades will rub against various raw materials, which may easily cause some raw materials to heat up and undergo qualitative changes, reducing the stirring effect of the slurry, thereby affecting the quality of the quartz crucible. Therefore, those skilled in the art provide a quartz sand slurry stirring device for square crucible production to solve the problems raised in the above-mentioned background technology.

[0023] Combination Figure 1-Figure 6 As shown, a cavity 101 is provided inside the tank body 1, and the inner tank 2 is installed inside the cavity 101, and a first spiral groove 102 is provided on the inner wall of the cavity 101, and a second spiral groove 201 is provided on the outer wall of the inner tank 2 at a position corresponding to the first spiral groove 102, and the second spiral groove 201 is fitted with the first spiral groove 102, and a water inlet 103 and a water outlet 104 are respectively provided at positions corresponding to the end and tail of the first spiral groove 102 on the outer wall of the tank body 1, and the water inlet 103 and the water outlet 104 are respectively provided. 04 are both connected with the first spiral groove 102 and the second spiral groove 201, and a threaded ear 11 is arranged on the outer side of the opening of the cavity 101 around the upper end surface of the tank body 1, and an annular ear 21 is arranged on the outer wall of the inner tank 2 located above the tank body 1, and the annular ear 21 is engaged with the inside of the threaded ear 11 and tightly attached to the upper end surface of the tank body 1, and a tank cover 3 for closing the opening of the cavity 101 is arranged above the tank body 1, and the tank cover 3 is threadedly mounted on the outer wall of the threaded ear 11 and pressed tightly against the upper end surface of the annular ear 21.

[0024] In one embodiment, when cooling the slurry in the tank body 1, the cooling water pipes at the input end and the output end of the water tank can be installed on the water inlet pipe 12 and the drain pipe 13 respectively, so that the cooling water inside the water tank can flow into the cooling water pipe and enter the water inlet pipe 12 through the pumping of the water pump, and the cooling water can flow from the water inlet 103 into the spiral cooling channel composed of the first spiral groove 102 and the second spiral groove 201, and then the cooling water can flow through the spiral cooling channel and flow from the water outlet 104 into the drain pipe 13, and the cooling water can flow through the drain pipe 13 and the cooling water. The water pipe enters the water tank, completing the circulation of cooling water, and can allow the cooling water to circulate in the spiral cooling channel to cool the slurry, preventing various raw materials from heating up due to friction with the stirring blades, and avoiding the quality of the crucible green body caused by the heating and deterioration of some substances in the slurry. In addition, when the slurry is kept warm, the temperature of the cooling water circulating in the spiral cooling channel can be changed according to the temperature of the slurry, so that the temperature of the cooling water is consistent with the temperature of the slurry, preventing the temperature of the slurry in the inner tank 2 from losing, thereby realizing temperature control of the quartz sand slurry and improving the quality of the quartz crucible.

[0025] In one embodiment, when the cooling water flows into the spiral cooling channel, since the diameter of the inner tank 2 is the same as the inner diameter of the cavity 101, the outer wall of the inner tank 2 is tightly attached to the inner wall of the cavity 101, so that the first spiral groove 102 and the second spiral groove 201 can fit tightly, and the cooling water will not leak in the spiral cooling channel. The cooling water can flow around the outer wall of the inner tank 2, thereby improving the cooling effect on the inner tank 2 and having strong practicality. Moreover, after long-term use, the annular support ear 21 can be directly pulled out from the annular groove 105 to remove the inner tank 2 from the cavity 101, and the inner wall of the tank body 1 and the outer wall of the inner tank 2 can be cleaned, thereby avoiding the blockage of the spiral cooling channel caused by scale generated on the inner wall of the tank body 1 and the outer wall of the inner tank 2, ensuring the circulation of cooling water, and facilitating the subsequent maintenance work.

[0026] In one embodiment, when various raw materials are stirred, various raw materials can be first placed in the inner tank 2 in a certain proportion, and the tank cover 3 can be covered on the top of the tank body 1 to seal the tank body 1 and the inner tank 2. The tank cover 3 can then be installed on the threaded ear 11 through the threaded groove 301, so that the tank cover 3 is pressed tightly against the upper end surface of the annular ear 21 on the top of the inner tank 2 to limit the position of the inner tank 2 and prevent the inner tank 2 from shaking. This avoids the leakage of cooling water in the spiral cooling channel caused by the inner tank 2 shaking up and down in the cavity 101. In addition, the gap between the tank cover 3 and the inner tank 2 can be sealed by the sealing gasket 22 to prevent the slurry from shaking during stirring, thus avoiding the trouble of slurry waste caused by the slurry shaking to the outside of the inner tank 2 during stirring. This has strong practicality.

[0027] The working principle of the utility model is as follows: when mixing the quartz crucible slurry, various raw materials can be put into the inner tank 2 in a certain proportion, and the tank cover 3 can be covered on the top of the tank body 1 to seal the tank body 1 and the inner tank 2, and then the tank cover 3 can be installed on the threaded lug 11 through the threaded groove 301, and the raw materials in the inner tank 2 can be stirred by the stirring motor and the stirring rod installed on the tank cover 3. At the same time, the cooling water pipes at the input end and the output end of the water tank are respectively installed on the water inlet pipe 12 and the drain pipe 13, so that the cooling water inside the water tank can flow into the cooling water pipe and the water inlet pipe 12 through the pumping of the water pump, and the cooling water can flow from the water inlet 103 into the spiral cooling channel composed of the first spiral groove 102 and the second spiral groove 201. The cooling water is then allowed to flow through the spiral cooling channel and flow from the water outlet 104 into the drain pipe 13, and the cooling water is allowed to flow through the drain pipe 13 and the cooling water pipe into the water tank, completing the circulation of the cooling water. The cooling water can circulate in the spiral cooling channel to cool the slurry, prevent the various raw materials from heating up due to friction with the stirring blades, and avoid the situation where the quality of the crucible green body is affected by the heating and deterioration of some substances in the slurry, thereby improving the quality of the quartz crucible. In addition, when the slurry is kept warm, the temperature of the cooling water circulating into the spiral cooling channel can be changed according to the temperature of the slurry, so that the temperature of the cooling water is consistent with the temperature of the slurry, thereby preventing the temperature of the slurry in the inner tank 2 from being lost, thereby achieving temperature control of the quartz sand slurry.
