Description

Technical Field

[0001] The utility model belongs to the technical field of quartz sand purification, and in particular relates to a quartz sand drying centrifuge. Background Art

[0002] The main purpose of quartz sand purification is to remove mineral impurities, metal ions, organic matter, etc., and improve the purity of silicon dioxide (SiO2). High-purity quartz sand is widely used in many high-tech fields such as semiconductors, optical fibers, solar energy, and glass manufacturing. Quartz sand purification methods are mainly divided into two categories: physical method and chemical method, as well as a comprehensive method combining the two. The physical method includes water washing: physical impurities such as mud and impurities in quartz sand are removed by water washing. Water washing is a basic pretreatment method that can increase the purity of quartz sand to about 90% to 95%.

[0003] After the quartz sand is washed by water, the physical impurities such as mud and dust attached to its surface will be removed, making the quartz sand cleaner. Then, the wet quartz sand will be sent to the drying equipment, and the excess water will be quickly removed through the action of centrifugal force to achieve a certain degree of dryness. The dried quartz sand is not only convenient for subsequent storage and transportation, but also provides better conditions for further purification. Next, the dried quartz sand will enter the next stage of purification or processing as needed.

[0004] The existing quartz sand drying device generally relies on filter bags to carry quartz sand during operation, and places and lifts the quartz sand through a crane. Although this method can effectively achieve the drying of quartz sand, after the drying is completed, it is necessary to manually operate the fixing assembly to cancel the fixation of the filter bag, and use the crane again to lift the filter bag together with the quartz sand from the drying device, and then open the discharge port at the bottom of the filter bag to discharge the quartz sand. This process not only increases the labor intensity of the operator, but also involves multiple fixing and releasing steps, as well as repeated use of the crane, which makes the unloading rate of the quartz sand relatively slow, affecting the quartz sand drying efficiency. Utility Model Content

[0005] The utility model aims to provide a quartz sand drying centrifuge to solve the problem that the quartz sand unloading rate is relatively slow due to multiple fixing and unfixing steps and repeated use of a crane, thus affecting the quartz sand drying efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quartz sand drying centrifuge, comprising an outer tank, an inner tank is arranged inside the outer tank, a plurality of water filtering holes are opened on the inner tank, a protrusion is arranged on the top of the inner tank, and a thread is arranged on the outer wall of the inner tank below the annular protrusion, an annular pressing member is threadedly sleeved on the top of the inner tank through a thread, a collecting member is arranged between the outer tank and the inner tank, the collecting member comprises a circular ring segment, a truncated cone segment and a collecting segment, the circular ring segment can be rotatably sleeved on the inner tank, the truncated cone segment connects the circular ring segment and the collecting segment, and the side of the collecting segment away from the circular ring segment is connected to the inner wall of the outer tank;

[0007] A filter bag is placed inside the inner tank.

[0008] Furthermore, the bottom of the inner tank is mounted on the output shaft of the driving motor, and the driving motor is mounted on the bottom of the outer tank.

[0009] Furthermore, an outer ring member is rotatably sleeved on the bottom of the inner tank, and the outer ring member is mounted on the inner wall of the outer tank through a plurality of connecting rods.

[0010] Furthermore, a No. 1 groove is provided at the bottom of the inner tank, a No. 2 groove is provided at the inner wall of the outer ring, and balls are provided in both the No. 1 groove and the No. 2 groove.

[0011] Furthermore, a handle is connected to the annular pressing member.

[0012] Furthermore, a hanging ring is provided in the middle of the inner cavity of the filter bag.

[0013] Furthermore, the top of the inner tank is arc-shaped.

[0014] Furthermore, a sealing cover is hingedly provided on one side of the outer tank, and an inner tank cover plate is rotatably provided in the middle of the sealing cover.

[0015] Furthermore, the collecting section is in a circular ring shape, the middle height of the top of the collecting section is higher than the heights on both sides to form a slope, and the outer tank is provided with a material receiving port at the lowest point of the slope.

[0016] Furthermore, a water outlet pipe is provided at the bottom of one side of the outer tank.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The quartz sand drying centrifuge achieves a stable clamping of the filter bag through the design of the clamping piece and the protrusion. After the drying operation is completed, the operator can use the crane to easily and accurately lift and flip the filter bag as a whole through the lifting ring in the middle of the filter bag. Under the natural effect of gravity, the quartz sand falls onto the collecting piece between the outer tank and the inner tank, thus achieving efficient and orderly collection of the quartz sand after drying. There is no need to lift the filter bag for bottom discharge, which improves the operating convenience and work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A lifting ring 410 is provided in the middle of the inner cavity of the filter bag 40 . The filter bag 40 is lifted up in the middle by the lifting ring 410 and the crane, so that the quartz sand inside the filter bag 40 falls outward and falls onto the collecting piece 340 between the outer tank 10 and the inner tank 30 .

[0033] See also Figure 1 , Figure 2 , Figure 4The collecting member 340 includes a circular segment 341, a truncated cone segment 342 and a collecting segment 343.

[0036] The working principle and use process of the utility model are as follows: (1) Installation: The bottom of the filter bag 40 is sleeved on the cylindrical member 310, and the top of the filter bag 40 is flipped to below the protrusion 303, and then the clamping member 330 is rotated upward by the handle 331, so that the clamping member 330 and the protrusion 303 clamp the filter bag 40.

[0037] (2) Dehydration: Pour quartz sand into the filter bag 40, close the sealing cover 50 to prevent the quartz sand from being thrown out during high-speed rotation, and drive the inner tank 30 to rotate through the driving motor 20. Under the action of centrifugal force, the filter bag is close to the inner wall of the inner tank 30, and the water inside the quartz sand will be thrown out.
