Description

Technical Field

[0001] The present application relates to the field of quartz sand processing, and in particular to a quartz sand pickling device. Background Art

[0002] Quartz sand is generally obtained from ore through screening, magnetic separation, flotation, pickling and other steps. During the processing, in order to improve the purity of quartz sand, quartz sand needs to be pickled.

[0003] At present, there are two main methods for pickling quartz sand: static pickling and dynamic pickling. Static pickling is to soak the quartz sand in the pickling solution, and dynamic pickling is to put the quartz sand into the pickling tank, continuously add new pickling solution into the tank, and continuously discharge the old pickling solution to keep the pH value within a certain range.

[0004] However, during the static pickling process, the contact area between the quartz sand and the pickling liquid is limited, resulting in low impurity removal efficiency and a long time consumption. In the dynamic pickling process, the quartz sand is flushed by continuously introducing the pickling liquid, resulting in a large consumption of the pickling liquid. Utility Model Content

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a quartz sand pickling device. Figure 1 and Figure 2A quartz sand pickling device includes a tank body 2 with an opening at the top. The tank body 2 includes a barrel 21 and a tapered portion 22. The barrel 21 is cylindrical, and the diameter of the tapered portion 22 gradually decreases as it moves away from the barrel 21. A drain pipe 5 is coaxially fixed to the bottom of the tank body 2, that is, the end of the tapered portion 22 away from the barrel 21. The drain pipe 5 is connected to the inside of the tank body 2 and is controlled by an electromagnetic valve. A sieve plate 8 is fixed in the tank body 2. The sieve plate 8 is located at one end of the cylinder 21 close to the cone 22, and its diameter is consistent with the inner diameter of the cylinder 21. A plurality of sieve holes 9 are provided on the sieve plate 8, and the plurality of sieve holes 9 are evenly spaced. The tank body 2 is provided with an inflation component 3 for inflating the pickling liquid and quartz sand in the tank body 2, and the tank body 2 is provided with an ultrasonic component 7 for ultrasonically applying ultrasound to the quartz sand and the pickling liquid. After the pickling is completed, in order to facilitate the discharge of the quartz sand, the tank body 2 is provided with a sand discharge component 4 for discharging the quartz sand on the sieve plate 8.

[0034] In the embodiment of the present application, in order to facilitate the inflation of the tank body 2 from the bottom of the tank body 2, refer to Figure 1 The aeration assembly 3 includes a fan 31 and an aeration pipe 32. The fan 31 is fixed to the outer wall of the barrel 21. One end of the aeration pipe 32 is connected to the output end of the fan 31, and the other end is connected to the drain pipe 5. Specifically, the fan 31 is located at the end of the barrel 21 away from the conical portion 22 and is fixed to the outer wall of the barrel 21. The end of the aeration pipe 32 away from the fan 31 is connected to the peripheral wall of the drain pipe 5. When the quartz sand needs to be pickled, the fan 31 is started and compresses the air. The air is then filled into the tank body 2 through the aeration pipe 32 and the drain pipe 5. Since the drain pipe 5 is coaxially arranged with the tank body 2, the uniform diffusion of the compressed air into the surrounding area when entering the tank body 2 is improved. Moreover, when the compressed air passes through the sieve plate 8, the evenly distributed sieve holes 9 on the sieve plate 8 further disperse the compressed air, thereby facilitating contact with the quartz sand. This also improves the uniformity of the compressed air distribution. In other embodiments, the end of the inflation tube 32 away from the fan 31 is connected to the outer wall of the cone 22 of the tank body 2, and the inflation tube 32 is connected to the inside of the tank body 2, and the compressed gas can enter the tank body 2 from below the sieve plate 8.

[0035] After the quartz sand is pickled, in order to discharge the quartz sand from the tank body 2, the fan 31 is first turned off. At this time, the quartz sand falls onto the sieve plate 8 under the action of gravity. The solenoid valve on the drain pipe 5 is controlled to open the drain pipe 5 to discharge the pickling liquid in the tank body 2. Finally, the quartz sand is discharged from the sieve plate 8 to the tank body 2 through the sand discharge assembly 4. Figure 2 and Figure 3The cylindrical portion 21 has an inlet hole 15 and a sand outlet hole 16 formed on its circumferential wall. Both the inlet hole 15 and the sand outlet hole 16 are located on the side of the sieve plate 8 away from the conical portion 22, i.e., on the sieve plate 8. The bottom side of the sand outlet hole 16 is flush with the upper surface of the sieve plate 8, and the inlet hole 15 is higher than the upper surface of the sieve plate 8. The sand discharge assembly 4 includes an inlet pipe 41 and a sand outlet pipe 42. One end of the inlet pipe 41 is connected to the cylindrical portion 21 through the inlet hole 15, and the other end is connected to the external high-pressure fluid and is opened and closed by a solenoid valve. The sand outlet pipe 42 is connected to the cylindrical portion 21 through the sand outlet hole 16. A sealing member is provided on the sand outlet pipe 42. Specifically, the sand outlet pipe 42 is bent, with one end close to the tank body 2 in the horizontal direction and the other end in the vertical direction, so that the quartz sand can fall under the action of gravity. The sealing member is provided on the end of the sand outlet pipe 42 close to the tank body 2.

[0036] In order to facilitate the opening and closing of the sand pipe 42, refer to Figure 3 The sand outlet pipe 42 is provided with a plug-in hole 14 on its peripheral wall. In the embodiment of the present application, the plug-in hole 14 is located on the upper peripheral wall of the sand outlet pipe 42. In other embodiments, the plug-in hole 14 can be provided on any side peripheral wall of the sand outlet pipe 42 except the lower side. The blocking member includes a blocking plate 10, which is movably connected to the plug-in hole 14. Furthermore, in order to improve the stability of the blocking plate 10 when inserting and withdrawing the sand outlet pipe 42, a limiting groove 13 is provided on the inner wall of the sand outlet pipe 42. The limiting groove 13 is U-shaped, and its opening is arranged toward the plug-in hole 14. The blocking plate 10 is plugged and matched with the limiting groove 13, that is, the thickness of the blocking plate 10 is consistent with the width of the limiting groove 13.

[0037] In order to facilitate the control of the blocking plate 10, refer to Figure 3 The opening of the plug hole 14 on the sand outlet tube 42 is stepped. A limit plate 11 is fixed to one end of the sealing plate 10 located outside the sand outlet tube 42. The limit plate 11 is embedded in the stepped portion of the plug hole 14 and abuts against the outer wall of the sand outlet tube 42. The side of the limit plate 11 away from the sealing plate 10 is flush with the side of the opening of the plug hole 14 of the sand outlet tube 42. A handle 12 is fixed to the surface of the limit plate 11 away from the sealing plate 10.

[0038] After the quartz sand is pickled, the inlet pipe 41 is opened through the solenoid valve on the inlet pipe 41, so that the external high-pressure fluid impacts the quartz sand on the sieve plate 8, and at the same time, the sealing plate 10 is pulled out of the sand outlet pipe 42 through the handle 12, thereby flushing the quartz sand into the sand outlet pipe 42, and then discharged from the tank body 2 along the sand outlet pipe 42.

[0039] Reference Figure 1 The ultrasonic component 7 uses an ultrasonic vibration plate, which is fixed on the inner wall of the cylindrical portion 21 of the tank body 2, so as to ultrasonically treat the quartz sand and the pickling liquid, and utilizes the cavitation effect to further improve the impurity removal efficiency of the quartz sand.

[0040] In order to avoid as much as possible the impurities from entering the tank from the opening of the tank body 2 during the process of pickling and discharging the quartz sand, refer to Figure 1 The opening of the tank body 2 is covered with a cover plate 1. Furthermore, in order to balance the air pressure in the tank body 2 when the inflation component 3 inflates the tank body 2, a plurality of air holes 6 are provided on the cover plate 1.

[0041] The implementation principle of a quartz sand pickling device in an embodiment of the present application is as follows: quartz sand and pickling liquid are added into the tank body 2 through the top opening of the tank body 2, and then the cover plate 1 is covered. When the quartz sand needs to be pickled, the fan 31 is started, the fan 31 compresses the air, and then fills it into the tank body 2 through the inflation pipe 32 and the discharge pipe 5. The compressed gas passes through the sieve holes 9 on the sieve plate 8 and blows the quartz sand, so that the quartz sand is suspended in the pickling liquid and the quartz sand and the pickling liquid are in a dynamic contact state. The ultrasonic vibration plate is started to perform ultrasonic treatment on the dynamic quartz sand and the pickling liquid. After the quartz sand is pickled, in order to discharge the quartz sand from the tank body 2, the fan 31 and the ultrasonic vibration plate are first turned off. At this time, the quartz sand falls onto the sieve plate 8 under the action of gravity, and the drain pipe 5 is opened by the solenoid valve on the drain pipe 5 to discharge the pickling liquid in the tank body 2. Finally, the inlet pipe 41 is opened by the solenoid valve on the inlet pipe 41, so that the external high-pressure fluid impacts the quartz sand on the sieve plate 8. At the same time, the sealing plate 10 is pulled out of the sand outlet pipe 42 through the handle 12, so that the quartz sand is flushed into the sand outlet pipe 42, and then discharged from the tank body 2 along the sand outlet pipe 42.
