Description

Technical Field

[0001] The invention relates to the technical field of glass preparation, in particular to quartz sand acid leaching processing equipment for glass preparation. Background Art

[0002] High-purity quartz sand is a very stable neutral mineral filler that does not contain crystalline water and will not react chemically with the filled material. Therefore, it is widely used in the field of glass preparation.

[0003] In the selection of refined quartz sand and high-purity quartz sand, in order to better improve the quality and output of quartz sand purification, combined with the characteristics of quartz sand being insoluble in acid and slightly soluble in KOH solution, it is necessary to use acid leaching to treat quartz sand. After acid leaching, sodium hydroxide is needed to neutralize the quartz sand until all the quartz sand is neutralized and the alkali solution is released.

[0004] Most of the existing quartz sand neutralization and deacidification are carried out in the same tank body as the acid leaching. Since the quartz sands are piled together and the quartz sands are in the form of fine particles, it is difficult to ensure that the quartz sands at the bottom are fully neutralized during neutralization. It takes a long time to ensure that the neutralization is in place, and the alkali solution slowly penetrates to the bottom to neutralize the quartz sands, so the efficiency is relatively low. For example, a high-purity quartz sand acid leaching processing equipment with a Chinese authorization publication number of CN115991477B can completely neutralize the quartz sand through the material washing mechanism to ensure the quality of the quartz sand acid leaching, but there are the following defects: the quartz sand to be neutralized in the tank body is transported to the top of the material receiving box by the lifting unit to transport the quartz sand in the material grabbing box to the top of the material receiving box, which has a complex structure, and it is also necessary to complete the sealing between the washing chamber and the tank body to prevent the quartz sand from flowing into the tank body again, and the quartz sand is taken out of the tank body in turn for neutralization and cleaning in batches. Compared with the traditional quartz sand neutralization, although the neutralization quality can be improved, the neutralization efficiency is still not high. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 The present invention is described in further detail.

[0034] Embodiment 1

[0036] The movable neutralization frame includes a frame body 7 sleeved on a rotating shaft 6, a discharge port 8 is provided on the lower surface of the frame body 7, and an intermittent drive mechanism 9 is connected to the input side of the rotating shaft 6; specifically, Figure 2The frame 7 is divided into three chambers by a partition, namely, a collection chamber 701, a neutralization chamber 702 and a discharge chamber 703. The discharge port 8 is arranged on the lower surface of the discharge chamber 703, and the three chambers are not connected to each other. When the frame 7 rotates intermittently with the rotating shaft 6 as the center, the collection chamber 701, the neutralization chamber 702 and the discharge chamber 703 are switched in sequence, so as to realize the uninterrupted discharge, neutralization and discharge of the quartz sand in the tank body 1. One end of the rotating shaft 6 is plugged into the center of the lower surface of the tank body 1, and the other end is plugged into the center of the bracket 2. The intermittent drive mechanism 9 is composed of an incomplete gear 901, a rotating gear 902 and a motor. The output end of the motor is plugged into the center of the incomplete gear 901. The incomplete gear 901 cooperates with the rotating gear 902, and the rotating gear 902 is sleeved on the rotating shaft 6; the gear ratio of the gear teeth on the surface of the incomplete gear 901 to the rotating gear 902 is 1:3. When the incomplete gear 901 rotates one circle, the rotating gear 902 rotates one third of a circle, thereby realizing the intermittent conversion of the three chambers.

[0037] The mixing mechanism includes a mixer 10 located in the frame 7. Specifically, the mixer 10 includes a mixing shaft 1001 respectively inserted into the three chambers. The outer wall of the mixing shaft 1001 is evenly distributed with multiple mixing plates 1002. The mixing plates 1002 are provided with multiple mixing rods on the side facing the bottom of the inner cavity of the chamber. When the mixing shaft 1001 rotates, the multiple mixing plates 1002 will rotate with the mixing shaft 1001 as the center, thereby driving the lower mixing rod to stir the quartz sand located in the frame 7. By arranging the mixer 10 in each chamber, when collecting materials, the mixer 10 can break up the fallen quartz sand, which is not easy to accumulate, and is convenient for mixing with sodium hydroxide alkali solution later. When neutralizing, the mixer 10 can promote the contact between the sodium hydroxide alkali solution and the quartz sand after acid leaching to ensure the quality of neutralization. When discharging, the mixer 10 can effectively discharge the neutralized quartz sand from the discharge port 8. The input side of the mixer 10 is connected to the rotating shaft 6 through a transmission structure; specifically, the transmission structure includes a ring gear 13 fixed on the bracket 2, a support plate 14 is laterally fixed to the side wall of the rotating shaft 6, and a driven gear 15 is connected to the end of the support plate 14 away from the rotating shaft 6, and the driven gear 15 is meshed with the inner wall of the ring gear 13, and a mixing shaft 1001 is fixedly inserted at the center of the driven gear 15, that is, when the rotating shaft 6 rotates, it will drive the driven gear 15 at one end of the support plate 14 to rotate, and under the action of the teeth on the inner wall of the ring gear 13, the driven gear 15 will rotate, and it is stationary relative to each chamber to achieve mixing in each chamber.

[0038] The material discharge control mechanism includes valves 11 located at the first discharge port 3, the second discharge port 5 and the discharge port 8; the first discharge port 3, the second discharge port 5 and the discharge port 8 are arranged at equal angles with the rotating shaft 6 as the axis, that is, the first discharge port 3, the second discharge port 5 and the discharge port 8 in this embodiment control the discharge of the processed quartz sand above through the corresponding valves 11, and the corresponding rotating shaft 6 is provided with a cam 12 for sequentially controlling the opening of each valve 11; the cam 12 includes a raised portion 1201 for controlling the movement of the valve plate 1103 to sequentially open the first discharge port 3, the second discharge port 5 and the discharge port 8, and there is a recessed portion 1202 in the arc transition between adjacent raised portions 1201. After the rotating gear 902 rotates one-third of a circle, one side of the valve plate 1103 is located at the edge of the raised portion 1201. Specifically, in combination with Figure 3 The material valve 11 includes a fixed plate 1101, a guide rod 1102 passing through the fixed plate 1101, a valve plate 1103 is provided at one end of the guide rod 1102, and a spring 1104 is provided between the valve plate 1103 and the fixed plate 1101. Since the first discharge port 3, the second discharge port 5 and the discharge port 8 correspond to the discharge of the tank body 1, the discharge of the alkali liquid barrel 4 and the discharge of the discharge cavity 703 respectively, by setting the first discharge port 3, the second discharge port 5 and the discharge port 8 at corresponding positions respectively, when the rotating shaft 6 rotates intermittently, the raised portion 1201 of the cam 12 will pass through the material valve 11 at the first discharge port 3, the second discharge port 5 and the discharge port 8 in sequence. It should be noted that the projection area of ​​the raised portion 1201 in the vertical direction is smaller than the area of ​​each chamber, so When the material collecting chamber 701, the neutralization chamber 702 and the discharge chamber 703 are converted in sequence, when the protrusion 1201 gradually opens the material valve 11, the material valve is already located above the chamber, so there will be no material spillage. When the material collecting chamber 701, the neutralization chamber 702 and the discharge chamber 703 are converted, the position of the protrusion 1201 is to open the material valve 11 to the maximum. When the three chambers are converted again, the material valve 11 will be closed under the action of the spring 1104 because the recessed portion 1201 gives way to avoid mixing of the three chambers.

[0039] As a preferred method of this embodiment, refer to Figure 1 The fixed plate 1101 at the first discharge port 3 and the second discharge port 5 is fixed on the tank body 1, and the fixed plate 1101 at the discharge port 8 is fixed on the side wall of the frame body 7. The valve plate 1103 at the discharge port 8 is different from the valve plates 1103 at the first discharge port 3 and the second discharge port 5. It adopts an L-shaped valve plate. The valve plates corresponding to the first discharge port, the second discharge port 5 and the discharge port 8 are all provided with matching discharge openings. The bottom of the L-shaped valve plate is located at the lower discharge port 8, and the top bypasses the side wall of the frame body 7 to cooperate with the cam 12. When the cam 12 rotates, it can synchronously drive the valve plates 1103 below the first discharge port 3, the second discharge port 5 and the discharge port 8 to move. Figure 4After the rotating gear 902 rotates one third of a circle, one side of the valve plate 1103 is located at the edge of the raised portion 1201, and the material can be unloaded after the rotation is completed.

[0040] Working principle: Start the motor of the intermittent drive mechanism 9. Driven by the output end of the motor, the three chambers in the frame 7 pass through the first discharge port 3, the second discharge port 5 and the discharge port 8 alternately in turn. During the process of passing through the first discharge port 3, the second discharge port 5 and the discharge port 8, the cam 12 will control the material valve 11 to open, that is, the acid-leached quartz sand in the tank body 1 is placed into the collection chamber 701. During the intermittent rotation process, when the collection chamber 701 rotates to the bottom of the alkali liquid barrel 4, it becomes a neutralization chamber. 702, the sodium hydroxide in the alkali liquid barrel 4 neutralizes the alkali liquid and acid-leaches the quartz sand to cause neutralization, and then rotates intermittently, and the neutralization chamber 702 becomes the discharge chamber 703, and the quartz sand in the discharge chamber 703 that has been neutralized is discharged, and this cycle is repeated to achieve uninterrupted discharge, neutralization, and discharge of the quartz sand in the tank body 1. At the same time, in this process, the mixer 10 located in the frame 7 can mix the material in each chamber, which promotes the neutralization quality and efficiency, does not need to be lifted, and reduces the processing cost.

[0041] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
