Description

Technical Field

[0001] The present invention belongs to the technical field of quartz sand water quenching equipment, and specifically refers to a high-purity quartz sand water quenching device. Background Art

[0002] Water quenching is a process of quickly placing quartz particles after high-temperature roasting into cold water for rapid cooling. During water quenching, the crystal volume suddenly decreases, and the internal stress at the crystal defects rapidly increases, prompting the crystal to crack at the defects. The main purpose of this step is to remove the air bubbles, water patterns, and some enclosed impurities inside the mineral, and at the same time expose the impurities in the inclusions and fissures in the original quartz on the particle surface for subsequent purification processes.

[0003] When quartz particles are roasted and water quenched, affected by temperature changes, the surface of the quartz particles will exfoliate, generating a large amount of small particles and powdered quartz. After the small particles and powdered quartz enter the water quenching pool, they will mix with water, making it difficult to be collected and conveyed by the conveyor belt, and will be lost with the water circulation. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a high-purity quartz sand water quenching device, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a high-purity quartz sand water quenching device, including: A water pool; A conveyor belt, the conveyor belt includes an input section and a lifting section, the input section is located inside the water pool, and the lifting section is located above the water pool; A water tank, arranged above the water pool, and a plurality of filtering units are provided at the bottom of the water tank; A conveying unit, connecting the water pool and the water tank, and conveying the water in the water pool to the water tank for filtration by the filtering units; Wherein, the filtering unit includes a filter cartridge, and the filter cartridge is connected to the water tank; A water collecting cylinder and a cooling cylinder are sequentially sleeved outside the filter cartridge. A water collecting cavity is provided between the filter cartridge and the water collecting cylinder, and a cooling cavity is provided between the water collecting cylinder and the cooling cylinder. An overflow hole for communicating the water collecting cavity and the cooling cavity is provided on the water collecting cylinder, and the overflow hole is located at the top of the water collecting cylinder, so that the water in the water collecting cavity can flow downward from the top of the cooling cavity for cooling, and a drain port is provided at the bottom of the cooling cylinder.

[0006] Further, the water tank is arranged above the lifting section of the conveyor belt, and the drainage direction of the drain port faces the lifting section of the conveyor belt.

[0007] Further, an ultrasonic transducer for generating ultrasonic waves is provided inside the water tank.

[0008] Further, a water outlet pipe corresponding to the number of the filtering units is provided at the bottom of the water tank. The water outlet pipe is communicated with the inside of the water tank, and the filter cartridge is connected to the water outlet pipe.

[0009] Further, a first threaded cap is provided at the top end of the filter cartridge, and an external thread corresponding to the first threaded cap is provided on the water outlet pipe. The filter cartridge is threadedly connected to the water outlet pipe through the first threaded cap.

[0010] Further, a second threaded cap corresponding to the first threaded cap is provided at the top end of the water collecting cylinder. The water collecting cylinder is threadedly connected to the first threaded cap through the second threaded cap.

[0011] Further, an internal thread corresponding to the second threaded cap is provided at the top end of the cooling cylinder. The cooling cylinder is threadedly connected to the second threaded cap.

[0012] Further, the conveying unit includes a conveying pipe and a conveying pump. One end of the conveying pipe is connected to the bottom of the water tank, the other end of the conveying pipe is connected to the top of the water tank, and the conveying pump is connected in series on the conveying pipe.

[0013] Further, a water collecting hopper for narrowing the drainage area is provided at the drainage port, so as to increase the drainage flow rate at the drainage port.

[0014] Further, a bamboo joint pipe capable of adjusting the drainage direction is provided at the bottom of the water collecting hopper.

[0015] The beneficial effects achieved by the present invention with the above structure are as follows: 1. By providing the filtering unit, the water inside the water tank is conveyed to the inside of the water tank by the conveying unit and filtered by the filtering unit. The filtered water falls back into the water tank again, while the powdered quartz sand in the water adheres to the inside of the filtering unit. The powdered quartz sand inside the filtering unit is regularly cleaned and the cleaned powdered quartz sand is collected and conveyed to the subsequent purification process, so as to fully recover the powdered quartz sand in the water and reduce the loss of quartz sand.

[0016] 2. By providing a water collecting cavity and a cooling cavity inside the filtering unit, the water filtered by the filter cartridge is collected in the water collecting cavity, then flows through the overflow hole at the top of the water collecting cylinder into the cooling cavity and flows downward along the top of the cooling cavity, so as to increase the flow path of the water and reduce the water temperature. Finally, since the water in the water tank is circulated and conveyed to the inside of the filtering unit by the conveying unit, the water can be cooled in a cycle, avoiding the increase of the water temperature in the water tank, thereby maintaining the water quenching effect of the quartz sand.

[0017] 3. By adjusting the drainage direction of the filtering unit, the discharged water can wash the lifting section of the conveyor belt and the quartz sand on the lifting section, wash the powdered quartz sand adhering to the conveyor belt and large - particle quartz sand into the pool, and be filtered and collected by the filtering unit, so as to fully separate the powdered quartz sand generated in the water quenching process from the large - particle quartz sand, which can reduce the power consumption during subsequent quartz sand crushing.

Together with the embodiments of the present invention, they are used to explain the present invention, and do not constitute a limitation to the present invention. Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a high-purity quartz sand water quenching device, which includes a water tank 1 and a conveyor belt 2. The conveyor belt 2 is provided with an input section and a lifting section. The input section of the conveyor belt 2 is located in the water tank 1, and the liquid level height of the water in the water tank 1 is above the input section of the conveyor belt 2.

[0024] The water tank 1 is located at the outlet of the roasting furnace, and the outlet of the roasting furnace extends above the input section of the conveyor belt 2. In this way, the quartz sand output from the outlet of the roasting furnace can fall into the input section of the conveyor belt 2 located in the water tank 1. And since the input section of the conveyor belt 2 is located in the water, the quartz sand falling into the input section of the conveyor belt 2 can contact the water in the water tank 1 to achieve water quenching of the quartz sand. At the same time, the conveyor belt 2 continuously conveys, and conveys the water-quenched quartz sand outside the water tank 1 for stacking and collection.

[0025] In a specific embodiment, the conveyor belt 2 adopts a mesh chain conveyor belt, and its conveying surface is composed of mesh chains with mesh holes. When the quartz sand is output from the water to the outside, it can play a role in draining water and separating the quartz sand from the water.

[0026] The lifting section of the conveyor belt 2 is located above the water tank 1. During the process of lifting the quartz sand, the residual water of the quartz sand drips downward and falls into the water tank 1, reducing the loss of water. Correspondingly, it can also reduce the loss of quartz sand in the water.

[0027] Combined with Figure 1 and Figure 2As shown in the figure, a water tank 3 is provided above the water pool 1. A plurality of filter units 4 are arranged in an array at the bottom of the water tank 3. The water pool 1 and the water tank 3 are connected by a conveying unit. The water inside the water pool 1 is conveyed to the inside of the water tank 3 through the conveying unit, distributed from the water tank 3 to the inside of the plurality of filter units 4, and the water is filtered by the filter units 4. The filtered water falls back into the water pool 1, and the powdered quartz sand in the water adheres to the inside of the filter units 4. The powdered quartz sand inside the filter units 4 is regularly cleaned and collected, and then conveyed to the subsequent purification process. While cleaning, the filtering effect of the filter units 4 can be restored.

[0028] In this way, during water quenching, the high-temperature quartz sand output from the outlet of the roasting furnace falls into the water pool 1, realizing the water quenching of the quartz sand. At the same time, the quartz sand falling into the water pool 1 is supported by the input section of the conveyor belt 2. As the conveyor belt 2 continuously conveys, the water-quenched quartz sand is conveyed out of the water pool 1 and stacked for collection. During the water quenching process, the conveying unit conveys the water inside the water pool 1 to the inside of the water tank 3, and it is filtered by the filter unit 4. The filtered water falls back into the water pool 1, while the powdered quartz sand in the water adheres to the inside of the filter unit 4. The powdered quartz sand inside the filter unit 4 is regularly cleaned and collected, and then conveyed to the subsequent purification process, fully recovering the powdered quartz sand in the water, reducing the loss of quartz sand, and while cleaning, the filtering effect of the filter unit 4 can be restored.

[0029] In a specific embodiment, the conveying unit includes a conveying pipe 32 and a conveying pump 33. One end of the conveying pipe 32 is connected to the bottom of the water pool 1, the other end of the conveying pipe 32 is connected to the top of the water tank 3, and the conveying pump 33 is connected in series on the conveying pipe 32. Under the pumping of the conveying pump 33, the water inside the water pool 1 is conveyed to the inside of the water tank 3 through the conveying pipe 32. And because the conveying pipe 32 is connected to the bottom of the water pool 1, therefore, the quartz sand deposited in the water pool 1 can also be conveyed into the water tank 3, fully filtering and collecting the powdered quartz sand in the water pool 1.

[0030] Correspondingly, the water in the water pool 1 is pumped and filtered from the bottom, and the filtered water falls into the water pool 1 from above the water pool 1, enabling the water in the water pool 1 to circulate.

[0031] Combined Figure 4 and Figure 5 As shown in the figure, the filter unit 4 includes a filter cylinder 41. The filter cylinder 41 is connected to the water tank 3 and is used for filtering and collecting powdered quartz sand.

[0032] In a specific embodiment, the filtering direction of the filter cylinder 41 is from the inside to the outside. The water in the water tank 3 flows into the inside of the filter cylinder 41 and permeates from the inside of the filter cylinder 41 to the outside of the filter cylinder 41. The powdered quartz sand in the water adheres to the inner wall of the filter cylinder 41. At the same time, the space inside the filter cylinder 41 can play a role in collecting quartz sand.

[0033] Further, a water collecting cylinder 42 and a cooling cylinder 43 are successively sleeved outside the filter cartridge 41. A water collecting cavity 401 is provided between the filter cartridge 41 and the water collecting cylinder 42, and a cooling cavity 402 is provided between the water collecting cylinder 42 and the cooling cylinder 43. An overflow hole 421 is provided on the water collecting cylinder 42, so that the water collecting cavity 401 and the cooling cavity 402 can communicate with each other, and the overflow hole 421 is located at the top of the water collecting cylinder 42. The water in the water collecting cavity 401 can flow downward from the top of the cooling cavity 402, increasing the flow path of the water, enabling the water to cool down, and a drain port is provided at the bottom of the cooling cylinder 43. The water in the cooling cavity 402 finally drains out to the water tank 1 through the drain port.

[0034] In this way, the water seeping out from the inside to the outside of the filter cartridge 41 is collected in the water collecting cavity 401, then flows into the cooling cavity 402 through the overflow hole 421 at the top of the water collecting cylinder 42, and flows downward along the top of the cooling cavity 402, thereby increasing the flow path of the water. During the flowing process of the water, the water temperature can be reduced. Finally, the water in the cooling cavity 402 drains out to the water tank 1 through the drain port. Since the water in the water tank 1 is circulated and transported to the filtering unit 4 by the conveying unit, the water can be cooled cyclically, preventing the water temperature in the water tank 1 from rising, and thus maintaining the water quenching effect of the quartz sand.

[0035] In an alternative embodiment, a set of fans can be arranged on one side of the water tank 3, and the blowing direction of the fans can be adjusted to face the filtering unit 4, and the blowing area of the fans can cover all the filtering units 4. By using the fans to blow air to the filtering unit 4, since the water in the filtering unit 4 finally flows downward from the outermost cooling cavity 402 (i.e., inside the cooling cylinder 43), the airflow blown by the fans can act on the outer wall of the cooling cylinder 43 and take away heat, thereby accelerating the cooling rate of the water in the cooling cavity 402.

[0036] Combined Figure 1 and Figure 2 As shown, the water tank 3 is specifically arranged above the lifting section of the conveyor belt 2, and the drainage direction of the drain port of the cooling cylinder 43 is towards the lifting section of the conveyor belt 2.

[0037] When the water filtered by the filtering unit 4 drains downward, it can wash the lifting section of the conveyor belt 2 and the quartz sand on the lifting section, washing the powdered quartz sand adhered to the conveyor belt 2 and the large - particle quartz sand into the water tank 1, so that the powdered quartz sand generated during the water quenching process is uniformly filtered and collected by the filtering unit 4, and the conveyor belt 2 outputs only large - particle quartz sand; Since the large - particle quartz sand needs to be further crushed and then ground, while the powdered quartz sand does not need further crushing, therefore, during water quenching, by using the flushing of the water flow to separate the powdered quartz sand from the large - particle quartz sand, the power consumption during the subsequent crushing of the quartz sand can be reduced.

[0038] Furthermore, an ultrasonic transducer 11 for generating ultrasonic waves is provided inside the water tank 1. The ultrasonic waves are used to clean the quartz sand in the water, causing the powdered quartz sand attached to the large-grained quartz sand to fall off into the water, thereby enhancing the separation effect between the large-grained quartz sand and the powdered quartz sand.

[0039] Combined with Figure 3 、 Figure 5 and Figure 6 As shown, the bottom of the water tank 3 is provided with water outlet pipes 31 corresponding to the number of the filtering units 4. The water outlet pipes 31 are in communication with the inside of the water tank 3, and the filter cartridges 41 are connected to the water outlet pipes 31.

[0040] In a specific embodiment, a first threaded cap 411 is provided at the top of the filter cartridge 41, and an external thread corresponding to the first threaded cap 411 is provided on the water outlet pipe 31. The filter cartridge 41 is threadedly connected to the water outlet pipe 31 through the first threaded cap 411.

[0041] In this way, the filter cartridge 41 can be quickly disassembled and assembled by using threaded connection, improving the cleaning efficiency of the filter cartridge 41.

[0042] Combined with Figure 5 and Figure 7 As shown, a second threaded cap 422 corresponding to the first threaded cap 411 is provided at the top of the water collecting cylinder 42. Threads are provided on both the inner and outer sides of the first threaded cap 411, and the water collecting cylinder 42 is threadedly connected to the outer side of the first threaded cap 411 through the second threaded cap 422.

[0043] In a specific embodiment, the tightening direction of the second threaded cap 422 is the same as that of the first threaded cap 411. When the second threaded cap 422 is threadedly connected and tightened with the first threaded cap 411, the first threaded cap 411 will not be dragged in the loosening direction and will maintain the tightened state with the water outlet pipe 31.

[0044] Combined with Figure 5 and Figure 8 As shown, an internal thread corresponding to the second threaded cap 422 is provided at the top of the cooling cylinder 43. Threads are provided on both the inner and outer sides of the second threaded cap 422, and the cooling cylinder 43 is threadedly connected to the outer side of the second threaded cap 422.

[0045] In a specific embodiment, the tightening direction of the cooling cylinder 43 is the same as that of the second threaded cap 422 and the first threaded cap 411. When the cooling cylinder 43 is threadedly connected and tightened with the second threaded cap 422, the first threaded cap 411 and the second threaded cap 422 will not be dragged in the loosening direction.

[0046] In an alternative embodiment, the connection sealing performance between the first threaded cap 411 and the water outlet pipe 31, between the second threaded cap 422 and the first threaded cap 411, and between the cooling cylinder 43 and the second threaded cap 422 can be increased by winding raw material tape.

[0047] Combined with Figure 4 and Figure 5 As shown, a water collecting hopper 431 for narrowing the drainage area is provided at the drainage outlet, so as to increase the drainage flow rate at the drainage outlet and enhance the flushing effect on the conveyor belt 2 and the quartz sand.

[0048] Furthermore, a corrugated pipe 432 capable of adjusting the drainage direction is provided at the bottom of the water collecting hopper 431. By adjusting the corrugated pipes 432 at the bottoms of multiple filtering units 4, the drainage can cover the conveying width of the conveyor belt 2, thereby improving the flushing effect on the conveyor belt 2 and the quartz sand.

[0049] Working principle of the present invention: During water quenching, water is added into the water tank 1, and the liquid level of the water is higher than the input section of the conveyor belt 2. The high-temperature quartz sand output from the outlet of the roasting furnace falls into the water tank 1, realizing the water quenching of the quartz sand. At the same time, the quartz sand falling into the water tank 1 is supported by the input section of the conveyor belt 2. As the conveyor belt 2 continuously conveys, the water-quenched quartz sand is conveyed out of the water tank 1 and stacked for collection; During the water quenching process, the conveying unit conveys the water inside the water tank 1 into the water tank 3, and it is filtered by the filter cartridge 41. The powdered quartz sand in the water adheres to the inside of the filter cartridge 41. The powdered quartz sand inside the filter cartridge 41 is regularly cleaned and collected, and then conveyed to the subsequent purification process, fully recovering the powdered quartz sand in the water, reducing the loss of quartz sand, and while cleaning, enabling the filtering unit 4 to restore the filtering effect; The water filtered by the filter cartridge 41 seeps outwards and converges into the water collecting cavity 401, and then flows through the overflow hole 421 at the top of the water collecting cylinder 42 into the cooling cavity 402, and flows downward along the top of the cooling cavity 402, thereby increasing the flow path of the water. During the flowing process of the water, the water temperature can be reduced. Finally, the water in the cooling cavity 402 is discharged into the water tank 1 through the drainage outlet. Since the water in the water tank 1 is circularly conveyed to the filtering unit 4 by the conveying unit, the water can be circularly cooled, preventing the water temperature in the water tank 1 from rising, thereby maintaining the water quenching effect of the quartz sand; A group of fans can be arranged on one side of the water tank 3, and the blowing direction of the fans is adjusted to face the filtering unit 4, and the blowing area of the fans can cover all the filtering units 4. The airflow blown by the fans can act on the outer wall of the cooling cylinder 43 and take away heat, thereby accelerating the cooling speed of the water in the cooling cavity 402; When the water filtered by the filtering unit 4 is discharged downward, it can flush the lifting section of the conveyor belt 2 and the quartz sand on the lifting section, washing the powdered quartz sand adhered to the conveyor belt 2 and the large-particle quartz sand into the water tank 1, so that the powdered quartz sand generated during the water quenching process is uniformly filtered and collected by the filtering unit 4. The quartz sand output by the conveyor belt 2 is all large-particle quartz sand. The large-particle quartz is further crushed and then purified, while the powdered quartz sand does not need to be further crushed; Therefore, during water quenching, by using the flushing of water flow to separate powdered quartz sand from large-grained quartz sand, the power consumption during subsequent crushing of quartz sand can be reduced; An ultrasonic transducer 11 for generating ultrasonic waves is provided inside the water tank 1, and the ultrasonic waves are used to clean the quartz sand in the water, so that the powdered quartz sand attached to the large-grained quartz sand falls off into the water, increasing the separation effect between the large-grained quartz sand and the powdered quartz sand.

[0050] In summary of the above embodiments: By setting up the filtering unit 4, the water inside the water tank 1 is transported to the inside of the water tank 3 by the conveying unit and filtered by the filtering unit 4. The filtered water falls back into the water tank 1 again, while the powdered quartz sand in the water adheres to the inside of the filtering unit 4. The powdered quartz sand inside the filtering unit 4 is cleaned regularly, and the cleaned powdered quartz sand is collected and transported to the subsequent purification process, fully recovering the powdered quartz sand in the water and reducing the loss of quartz sand.

[0051] By arranging a water collecting cavity 401 and a cooling cavity 402 inside the filtering unit 4, the water filtered by the filter cartridge 41 gathers in the water collecting cavity 401, then flows into the cooling cavity 402 through the overflow hole 421 at the top of the water collecting cylinder 42 and flows downward along the top of the cooling cavity 402, thereby increasing the flow path of the water and enabling the water temperature to be reduced. Finally, since the water in the water tank 1 is circulated and transported to the filtering unit 4 by the conveying unit, the water can be cooled in a cycle, preventing the water temperature in the water tank 1 from rising, and thus maintaining the water quenching effect of the quartz sand.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0053] The above describes the present invention and its implementation manners. Such description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
