Description

Technical Field

[0001] The utility model relates to the technical field of reaction impurity removal equipment, in particular to a potassium feldspar pickling and impurity removal device. Background Art

[0002] Potassium feldspar belongs to the monoclinic crystal system and is typically flesh-red, yellow-white, or other colors. Its characteristics include a low melting point, a long melting interval, and high melt viscosity. Therefore, potassium feldspar is widely used in industrial fields such as ceramic blanks, ceramic glazes, glass, electrical porcelain, abrasive materials, and potash fertilizer manufacturing.

[0003] In actual production, potassium feldspar undergoes a series of pretreatments before use. This includes removing dust and gravel, and using acid washing to remove impurities such as iron, aluminum, phosphorus, titanium, and calcium adhering to the surface of the potassium feldspar.

[0004] Currently, the pickling process for potassium feldspar generally involves the use of a reactor, where the potassium feldspar is deposited inside. During pickling, the appropriate cleaning solution is typically simply injected into the reactor. A stirring rod or stirring bar is then used to stir the potassium feldspar, increasing its contact area with the cleaning solution and thus improving the reaction efficiency.

[0005] However, in actual operation, we observed that the existing pickling process can only remove a thin layer of impurities attached to the surface of potassium feldspar. When the potassium feldspar surface contains a large amount of impurities, the required reaction time is significantly extended. Therefore, we believe it is necessary to develop a new potassium feldspar pickling and impurity removal device that can effectively separate the impurities from the potassium feldspar, thereby shortening the reaction time. Utility Model Content

[0006] In response to the shortcomings of the existing technology, this utility model proposes a potassium feldspar pickling and impurity removal device, which aims to shorten the reaction time. This device effectively solves the problem of excessively long reaction time and frequent incomplete reaction when treating potassium feldspar with a large amount of surface attachments in the current technology.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Please refer to Figure 1 As shown in the figure, the device is a device specially designed for pickling and removing impurities from potassium feldspar. Its unique structure can significantly improve the efficiency of impurity removal.

[0026] Similar to similar devices in the prior art, the main body of this device includes an outer shell 1, and a liquid outlet 8 is provided at the lower part of the outer shell 1, whose function is to discharge the processed liquid.

[0027] In addition, a liquid storage tank is firmly connected to the lower part of the outer shell 1, and a circulation pipe 2 is connected to one side of the liquid storage tank. The circulation pipe 2 is responsible for the circulation and transportation of the liquid, aiming to improve the utilization efficiency of the cleaning liquid.

[0028] Please refer to Figure 1 and Figure 2 As shown, compared with the existing device, the core innovation of this device lies in the addition of an axially arranged transfer tube 4. The upper portion of the transfer tube 4 is connected to the circulation pipe 2 through a connector 3 to achieve a rotational sealing connection, thereby ensuring the sealing performance of the liquid during the circulation process.

[0029] Specifically, if Figure 3 As shown, connector 3 primarily consists of a sleeve threadedly connected to adapter tube 4 and a rubber ring mounted on the outside of circulation tube 2. In practice, a corresponding receiving groove for the rubber ring is designed within the sleeve. When the rubber ring is inserted and secured within the receiving groove, a rotationally sealed connection is achieved between adapter tube 4 and circulation tube 2.

[0030] The lower portion of the transfer tube 4 is connected to multiple cleaning tubes 7, all arranged with their central axes horizontally. Each cleaning tube 7 has a water outlet 6 extending through its side end, with the central axis of the water outlet 6 perpendicular to the central axis of the corresponding cleaning tube 7. This ensures that the cleaning liquid is evenly sprayed onto the surface of the potassium feldspar, achieving optimal cleaning results.

[0031] In addition, if Figure 2 and Figure 4 As shown, a drive mechanism 9 is disposed on the lower side of the outer shell 1. This drive mechanism 9 includes a drive motor 903 arranged along the vertical axis. The output shaft of the drive motor 903 is connected to a follower shaft 902 via a key connection. The follower shaft 902 passes through a through hole at the lower end of the outer shell 1 and forms a rotationally sealed connection with the outer shell 1, thereby ensuring stable operation of the drive mechanism 9.

[0032] At the same time, the upper end of the follower shaft 902 is firmly connected to a fixing member 901 , and the fixing member 901 is fixedly connected to the plurality of cleaning pipes 7 via the connecting member 3 , so that the cleaning pipes 7 can rotate synchronously with the follower shaft 902 .

[0033] Specifically, the lower end of the outer shell 1 is provided with a through-hole, into which the fixing member 901 and the follower shaft 902 are inserted and secured. Furthermore, the outer portions of the fixing member 901 and the follower shaft 902 located within the through-hole are covered with rubber rings, the outer walls of which are fixedly connected to the outer shell 1. In this way, the rubber rings ensure a rotationally sealed connection between the fixing member 901, the follower shaft 902, and the outer shell 1.

[0034] In actual application, the multiple cleaning pipes 7 rotate around the central axis of the transfer pipe 4, which not only allows the cleaning liquid discharged from the water outlet 6 to effectively flush the potassium feldspar and completely remove the attachments on its surface, but also the movement of the cleaning pipes 7 inside the potassium feldspar can achieve a turning effect on the potassium feldspar, ensuring that each potassium feldspar is fully flushed.

[0035] Furthermore, this device features a specially designed outlet hole 6 at the side of the cleaning tube 7, comprising outlet hole I and outlet hole II. The central axis of outlet hole I is perpendicular to the central axis of the transfer tube 4, while the central axis of outlet hole II is parallel to the central axis of the transfer tube 4. This design allows the cleaning fluid sprayed from outlet hole II to form liquid lubrication between adjacent layers of potassium feldspar. This increases the frequency of exchange between the upper and lower layers of potassium feldspar as the cleaning tube 7 moves and stirs the potassium feldspar, achieving a comprehensive cleaning effect.

[0036] At the same time, water outlet hole I completely penetrates cleaning tube 7. This allows different cleaning purposes to be achieved according to different cleaning needs as cleaning tube 7 moves and stirs the potassium feldspar. Specifically, as cleaning tube 7 moves, it impacts the potassium feldspar, causing it to move up and down. At this time, some water outlet holes I are close to the potassium feldspar they impact, and the sprayed cleaning liquid has a strong impact on the potassium feldspar, ensuring that attached objects are knocked off. As cleaning tube 7 continues to move, the potassium feldspar at its upper and lower ends move toward each other due to lack of support, entering the radiation range of the other part of water outlet hole I. At this time, the potassium feldspar moving in opposite directions is far away from the cleaning liquid sprayed from water outlet hole I, and the radiation effect of the cleaning liquid is stronger, thereby expanding the radiation range of the cleaning liquid and ensuring that the potassium feldspar is thoroughly cleaned.

[0037] In addition, if Figure 2 、 Figure 5 、 Figure 6 As shown, the lower side of the outer shell 1 is further provided with a plurality of baffles 13, which are arranged in parallel and equidistantly around the central axis of the follower shaft 902. Each baffle 13 is provided with a through slot 16, which forms a one-to-one correspondence with the liquid outlet 8 to ensure smooth discharge of liquid.

[0038] Therefore, to effectively soak the potassium feldspar with the cleaning fluid and prolong the reaction time between the cleaning fluid and the potassium feldspar, this device utilizes a sliding connection with a positioning rod 14 on the side of each baffle 13 facing away from the driven disk 15. The end of the positioning rod 14 facing away from the driven disk 15 is fixedly connected to the outer shell 1 via a fixing plate 18. This utilizes the positioning rod 14 to achieve a sliding connection between the baffle 13 and the outer shell 1. By sliding the baffle 13, the corresponding relationship between the through slot 16 and the liquid outlet 8 can be flexibly adjusted.

[0039] Furthermore, in this device, a sealing gasket 17 is fixedly connected to the upper end of each baffle 13 , and the sealing gasket 17 is in close contact with the lower end surface of the outer shell 1 .

[0040] Furthermore, this device features a compression spring 19 sleeved around the outside of each positioning rod 14. The two axial ends of the compression spring 19 are in close contact with the fixed plate 18 and the baffle 13, respectively. This design ensures that the baffle 13 quickly returns to its original position when no external forces are acting on it. When the compression spring 19 is unaffected by external forces, the sealing gasket 17 is positioned directly below the liquid outlet 8, effectively preventing liquid leakage under normal conditions.

[0041] Specifically, this device features a driven disc 15 connected via a key to the output shaft of the drive shaft. This driven disc 15 is positioned on the underside of the outer shell 1. The operation of driven disc 15 enables the periodic movement of baffle 13, thereby periodically displacing the cleaning fluid within the outer shell 1. This ensures that the cleaning fluid remains within the effective range, thereby ensuring that the reaction rate between the cleaning fluid and potassium feldspar meets established requirements.

[0042] Specifically, a plurality of support rods 10 are fixedly connected to the upper end of the driven disk 15, and a one-to-one correspondence is formed between these support rods 10 and the plurality of baffles 13. Therefore, in actual application, by limiting the contact between the support rods 10 and the baffles 13, the positional relationship between the support rods 10 and the baffles 13 during the movement of the driven disk 15 can be utilized to ensure that when the support rods 10 contact the baffles 13, the through grooves 16 are located directly below the liquid outlet 8, thereby achieving smooth discharge of liquid.

[0043] Furthermore, this device features a special design for the side of each baffle 13 near the driven disk 15, with arcuate segments I 20 and II 21. The central axis of arcuate segment I 20 is located at the end of the baffle 13 facing away from the driven disk 15. In actual operation, when the support rod 10 contacts arcuate segment I 20, the baffle 13 moves toward the fixed plate 18, away from the driven disk 15, as the driven disk 15 moves. At this point, the horizontal projection areas of the liquid outlet 8 and the through-slot 16 increase, thereby enabling liquid discharge.

[0044] At the same time, the central axis of arc segment II 21 coincides with the central axis of driven shaft 902. This design ensures that when support rod 10 contacts baffle 13, the distance between baffle 13 and the central axis of driven disc 15 remains unchanged, thereby extending the time during which the horizontal projection area of ​​liquid outlet 8 coincides with the horizontal projection area of ​​through groove 16, ensuring that the liquid inside outer shell 1 can be completely discharged.

[0045] It should be noted that in actual operation, as the driven disk 15 rotates, a single support rod 10 will first contact arc segment I 20 and then arc segment II 21. Furthermore, a smooth transition is achieved between arc segment I 20 and arc segment II 21, which not only reduces impact but also ensures that when the support rod 10 contacts arc segment I 20, the horizontal projection areas of the liquid outlet 8 and the through-slot 16 are maximized, thereby ensuring that the liquid inside the outer shell 1 can be completely discharged.

[0046] Furthermore, a driven tube 12 is sleeved on the outer side of each support rod 10 , and the driven tube 12 is rotatably connected to the support rod 10 through a bearing 11 , thereby ensuring the rotational flexibility of the support rod 10 .

[0047] Furthermore, a support filter 5 is provided at the lower end of the outer shell 1 . The support filter 5 is arranged at the lower side of the cleaning pipe 7 , and its main function is to effectively prevent potassium feldspar from entering the liquid outlet 8 .

[0048] At the same time, in order to ensure that potassium feldspar does not embed into the filter holes of the supporting filter screen 5, the thickness of the supporting filter screen 5 is strictly controlled to be no more than five millimeters.

[0049] In actual application, this utility model:

[0050] The cleaning pipe 7 rotates around the central axis of the transfer tube 4, flushing debris from the surface of the potassium feldspar through the water outlet 6 and ensuring thorough cleaning by turning the potassium feldspar. The device features specially designed water outlets I and II: outlet I is perpendicular to the central axis of the transfer tube 4, while outlet II is parallel to it, achieving different cleaning effects. The underside of the outer shell 1 is equipped with a baffle 13, with a through slot 16 corresponding to the liquid outlet 8, facilitating the discharge of the cleaning fluid. The baffle 13 is connected to the outer shell 1 via a positioning rod 14 and a compression spring 19, enabling periodic movement to facilitate cleaning fluid replacement. The driven disc 15 is connected to the support rod 10, which works in conjunction with the baffle 13 to ensure smooth discharge of the cleaning fluid. The baffle 13 features an arc-shaped section to optimize the discharge of the cleaning fluid. Furthermore, a support filter 5 is installed below the cleaning pipe 7 to prevent potassium feldspar from accidentally entering the liquid outlet 8, and its thickness is controlled to within five millimeters.

[0051] In particular, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
