Description

Technical Field

[0001] This utility model relates to the field of quartz sand processing technology, specifically to a quartz sand water quenching device. Background Technology

[0002] The purification of quartz sand requires multiple processes, including crushing, calcination, water quenching, and acid washing. Among these, the water quenching process is a key link between high-temperature calcination and deep purification, and it directly determines the efficiency of impurity exposure and the subsequent purification cost.

[0003] The water quenching process involves rapid cooling after high-temperature calcination to create cracks inside the quartz sand, exposing inclusions and impurities for subsequent acid washing. However, during water quenching, the spray mechanism impacts the quartz sand in a single direction, which cannot fully wash the quartz sand, affecting the water quenching effect and hindering the subsequent deep purification of the quartz sand.

[0009] Each of the spraying mechanisms includes an annular support and multiple nozzles mounted on the annular support, wherein one nozzle is located in the hollow part of the annular support and is connected to the annular support by multiple connecting rods, and the remaining multiple nozzles are equidistantly distributed around the annular support along the inward edge of the annular support.

[0010] Each nozzle has multiple spray holes with different spray angles.

[0011] Furthermore, the inward-facing edge of each of the annular supports is trumpet-shaped, and the larger opening end of the trumpet-shaped annular support faces vertically upward.

[0012] Multiple nozzles, arranged around the corresponding annular support, are tilted along the flared edge.

[0013] Furthermore, among the multiple nozzles arranged in a ring, the spray angles of multiple water jets on the same nozzle are all oriented towards the corresponding nozzle axis, so that the water jets from multiple water jets with different spray angles on the same nozzle converge at the same point, and form an umbrella-shaped multi-jet stream during the convergence process.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This application provides a quartz sand water quenching device, which solves the problem of the spray mechanism impacting quartz sand in a single direction during the existing water quenching process, and realizes efficient water quenching of quartz sand.

[0039] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0040] In the existing technology, the water quenching process causes cracks to form inside the quartz sand after high-temperature calcination and rapid cooling, exposing inclusion impurities for subsequent acid washing to remove. However, during the water quenching process, the spraying mechanism impacts the quartz sand in a single direction, which cannot fully wash the quartz sand, affecting the water quenching effect and hindering the subsequent deep purification of the quartz sand.

[0041] Research has found that, for example Figures 1-9 As shown, by installing multiple spraying mechanisms inside the water quenching frame and setting multiple spray holes with different spray angles on the nozzles of the spraying mechanisms, the spraying mechanisms can impact the quartz sand from multiple angles and directions. This can fully expose the gas-liquid inclusions and impurities inside the quartz sand for subsequent acid washing and removal, achieving a better water quenching effect. The equipment has a high degree of automation, requires no large amount of manual operation, and reduces labor intensity and production costs.

[0042] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figures 1-5 As shown, a quartz sand water quenching device is used to water quench quartz sand after calcination in a calcining furnace, including a water quenching frame 1 and multiple spraying mechanisms 2 installed inside the water quenching frame 1.

[0044] Each of the spraying mechanisms 2 includes an annular support 21 and a plurality of nozzles 211 mounted on the annular support 21. One nozzle 211 is located in the hollow part of the annular support 21 and is connected to the annular support 21 by a plurality of connecting rods 212. The remaining plurality of nozzles 211 are distributed equidistantly around the inner edge of the annular support 21.

[0045] Each nozzle 211 has multiple spray holes 213 with different spray angles.

[0046] By installing multiple spray mechanisms 2 inside the water quenching frame 1, the calcined quartz sand is rapidly cooled by the spray mechanisms 2. The rapid cooling causes cracks to form inside the quartz sand, exposing inclusion impurities for subsequent acid washing to remove them.

[0047] Furthermore, during the water quenching process, by setting multiple water spray holes 213 with different spray angles on the nozzle 211, the spraying mechanism 2 can impact the quartz sand from multiple angles, thereby fully exposing the gas-liquid inclusions and impurities inside the quartz sand for subsequent acid washing and removal, achieving a better water quenching effect. The equipment has a high degree of automation, requiring no large amount of manual operation, thus reducing labor intensity and production costs.

[0048] Specifically, each of the spraying mechanisms 2 is fixedly connected to the water quenching frame 1 via a connector 20, and the connection between the connector 20 and the water quenching frame 1 can be fixed in a detachable manner or by welding.

[0049] Among them, the end of the connector 20 near the spray mechanism 2 is fixed to the annular support 21 on the spray mechanism 2 by welding;

[0050] Multiple spraying units 2 all use external water pumps to spray and cool the quartz sand.

[0051] like Figures 2-5 As shown, the inner edge of each of the annular supports 21 is trumpet-shaped, and the larger opening end of the trumpet-shaped annular support 21 is vertically upward.

[0052] Multiple nozzles 211 arranged around the corresponding annular support 21 are all tilted along the flared edge.

[0053] By setting the annular support 21 in a trumpet shape, the spraying range of the spraying mechanism 2 towards the direction of quartz sand falling is expanded. Combined with the design of water spray holes 213 at different angles on each nozzle 211, the multi-angle and multi-directional surrounding spray can fully expose the gas-liquid inclusions and impurities inside the quartz sand, thereby improving the water quenching effect of the quartz sand.

[0054] Specifically, when setting the spray angle of the spray holes 213 on the nozzle 211:

[0055] Among the multiple nozzles 211 arranged around each other, the spray angles of multiple water jet holes 213 located on the same nozzle 211 are all oriented towards the axis of the corresponding nozzle 211, so that the water jets from multiple water jet holes 213 with different spray angles on the same nozzle 211 converge at the same point and form an umbrella-shaped multi-jet stream during the convergence process.

[0056] While achieving multi-angle and multi-directional spraying, it can enhance the water spray intensity of nozzle 211;

[0057] Furthermore, the water jets from multiple nozzles 213 at different spray angles on the same nozzle 211 converge at the same point and form an umbrella-shaped multi-jet stream during the convergence process. Compared with the parallel multi-jet streams, the adjacent umbrella-shaped jet streams gradually approach each other during the spraying process. The quartz sand falling into the jet stream can receive a more thorough impact from multiple angles in a short time in the gradually approaching jet stream.

[0058] Specifically, when setting up spray mechanism 2:

[0059] Multiple spraying mechanisms 2 can be arranged in layers within the water quenching frame 1, and the multiple spraying mechanisms 2 between adjacent layers are arranged in a staggered and orderly manner so that the multiple spraying mechanisms 2 can achieve a better cooling effect on the water quenching of quartz sand.

[0060] like Figures 1-6 As shown, the multiple spraying mechanisms 2 located on the upper layer of the water quenching frame 1 correspond one-to-one with the multiple discharge furnace pipes 4 on the calcining furnace.

[0061] Each of the discharge furnace pipes 4 is located above the corresponding spraying mechanism 2, and the direction of free fall of the quartz sand falling from the discharge port of the discharge furnace pipe 4 is consistent with the axial direction of the corresponding spraying mechanism 2.

[0062] The trough-shaped spray mechanism 2 is used to impact the quartz sand that falls freely along the axis of the corresponding spray mechanism 2. The trough-shaped spray mechanism 2 can buffer the falling quartz sand, allowing the nozzle 211 to impact the quartz sand for a longer time, thereby achieving a better impact effect.

[0063] like Figures 2-3 As shown, a flow port 22 is formed between two adjacent nozzles 211 for the flow of quartz sand, so that the quartz sand falling onto the spraying mechanism 2 can flow out of the spraying mechanism 2 along the flow port 22.

[0064] like Figure 1 , Figures 7-9 As shown, each of the water-quenching frames 1 has two pads 10 at its bottom, and a cavity is formed between the two pads 10.

[0065] The bottom of the water quenching frame 1 is equipped with multiple sealing structures 11 that correspond one-to-one with the spraying mechanism 2;

[0066] Each sealing structure 11 is equipped with a water pumping pipe 30 and multiple spray pipes 3 that are connected to the water pumping pipe 30. The side of each spray pipe 3 away from the sealing structure 11 is connected to multiple spray holes 213 on the corresponding nozzle 211. The side of the multiple water pumping pipes 30 away from the sealing structure 11 is connected to a water pump through a pump pipe to control the spraying of multiple spraying mechanisms 2.

[0067] The multiple water pumping pipes 30 are all located inside the overhead cavity to facilitate the spraying operation of the spraying mechanism 2.

[0068] Specifically, when setting the discharge furnace pipe 4, the diameter of the discharge furnace pipe 4 is smaller than the outer diameter of the nozzle 211, so that the quartz sand discharged from the discharge furnace pipe 4 is within the scouring area of ​​the nozzle 211 directly below the discharge furnace pipe 4, which facilitates the quartz sand to achieve a better water quenching effect.

[0069] It should be noted that the sealing structure 11 has good sealing performance with the water quenching frame 1, the spray pipe 3 and the water pumping pipe 30, and the relevant parts of the water quenching equipment are resistant to high temperature, which can meet the water quenching requirements of quartz sand.

[0070] Specifically, multiple water suction pipes 30 and pump pipes form a multi-pass pipe to enable multiple spraying mechanisms 2 to spray water simultaneously.

[0071] During operation, the water quenching frame 1 equipped with the spraying mechanism 2 is placed below the corresponding discharge tube 4 of the calcining furnace. At this time, the discharge port of the discharge tube 4 is located at the center of the uppermost spraying mechanism 2, and the free fall direction of the quartz sand flowing out of the discharge port of the discharge tube 4 is consistent with the vertical direction of the corresponding spraying mechanism 2.

[0072] When the quartz sand is water quenched, the water pump is started and multiple spraying mechanisms 2 are controlled to perform spraying operations. During the spraying process, multiple nozzles 211 on the spraying mechanism 2 impact the quartz sand falling freely along the vertical direction of the spraying mechanism 2 at multiple different angles, which fully exposes the gas-liquid inclusions and impurities inside the quartz sand, improves the water quenching effect of the quartz sand, and facilitates the efficient acid washing and removal of the gas-liquid inclusions and exposed impurities inside the quartz sand in the subsequent process, thereby achieving the subsequent deep purification of the quartz sand.

[0073] Specifically, the installation of the spray pipe 3, the water pump 30, and the water pump on the spray mechanism 2 can be carried out using conventional installation methods, and the assembly of the spray mechanism 2 will not be described in detail here.

[0074] In summary, compared with existing technologies, it has the following beneficial effects:

[0075] 1. By installing multiple spray mechanisms 2 inside the water quenching frame 1, the calcined quartz sand is rapidly cooled by the spray mechanisms 2. The rapid cooling causes cracks to form inside the quartz sand, exposing inclusion impurities for subsequent acid washing to remove them.

[0076] Furthermore, during the water quenching process, by setting multiple water spray holes 213 with different spray angles on the nozzle 211, the spraying mechanism 2 can impact the quartz sand from multiple angles, thereby fully exposing the gas-liquid inclusions and impurities inside the quartz sand for subsequent acid washing and removal, achieving a better water quenching effect. The equipment has a high degree of automation, requiring no large amount of manual operation, thus reducing labor intensity and production costs.

[0077] 2. By setting the annular support 21 to a trumpet shape, the spraying range of the spraying mechanism 2 towards the direction of quartz sand falling is expanded. Combined with the design of water spray holes 213 at different angles on each nozzle 211, the multi-angle and multi-directional surrounding spray can fully expose the gas-liquid inclusions and impurities inside the quartz sand, thereby improving the water quenching effect of the quartz sand.

[0078] 3. By converging the water jets from multiple nozzles 213 at different spray angles on the same nozzle 211 at the same point, and forming an umbrella-shaped multi-jet stream during the convergence process, the adjacent umbrella-shaped jet streams gradually approach each other during the spraying process. The quartz sand falling into the jet stream can receive a more thorough impact from multiple angles in a short time in the gradually approaching jet stream.
