Description

Technical Field

[0001] This utility model relates to the field of quartz sand dewatering technology, specifically a dewatering device for the production of high-purity quartz sand. Background Technology

[0002] High-purity quartz sand is a key raw material in high-end fields such as semiconductors, photovoltaics, and optical fibers. The dehydration process in its production directly affects the purity of the product and the efficiency of subsequent processing. Traditional dehydration devices mostly use static filtration or centrifugal separation. Traditional dehydration devices lack an effective stirring mechanism and rely on gravity or simple vibration for dehydration, resulting in serious water retention between quartz sand particles. Therefore, a dehydration device for the production of high-purity quartz sand is proposed to solve the above problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The purpose of this invention is to solve the problem that traditional dewatering devices lack an effective stirring mechanism and rely on gravity or simple vibration for dewatering, resulting in severe water retention between quartz sand particles. Therefore, this invention proposes a dewatering device for the production of high-purity quartz sand.

[0005] (II) Technical Solution

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A dewatering device for producing high-purity quartz sand includes a frame. A dewatering cylinder is detachably connected to the inner side of the frame by bolts. The dewatering cylinder is inclined from left to right. Several crossbars are fixedly connected to the inner side of the dewatering cylinder. The distance between two adjacent crossbars is less than the diameter of the quartz sand. An outlet is opened at the bottom of the dewatering cylinder. A feed hopper is fixedly connected to the top of the dewatering cylinder. A rotating shaft is rotatably connected to the inner side of the dewatering cylinder. A rotating roller is fixedly connected to the outer side of the rotating shaft. Several protrusions are provided on the outer side of the rotating roller. A drive mechanism for rotating the rotating shaft is provided on the frame.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Preferably, the drive mechanism includes a drive motor, which is detachably connected to the frame by bolts. A transmission mechanism is fixedly connected to the outer side of the output end of the drive motor, and the transmission mechanism is fixedly connected to the outer side of the rotating shaft.

[0010] Preferably, a water outlet bucket is fixedly connected to the bottom end of the dehydration cylinder, and the bottom surface of the inner cavity of the water outlet bucket is arc-shaped.

[0011] Preferably, a discharge hopper is fixedly connected to the right end of the dewatering cylinder.

[0012] Preferably, the top of the frame is detachably connected to a rotating seat by bolts, and the rotating shaft is rotatably connected to the inner side of the rotating seat.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] This invention, by setting up a rotating shaft, rotating roller, driving mechanism, and protrusions, allows quartz sand raw material to enter the inclined dewatering cylinder from the feed hopper. The driving mechanism drives the rotating shaft to rotate, which in turn drives the rotating roller to rotate. Under the action of the rotating roller, a tumbling motion is generated. The protrusions drive the quartz sand to move, and the crossbars form a gap filter layer to prevent the quartz sand from falling directly. Under the action of gravity, the quartz sand moves slowly along the inclined direction of the dewatering cylinder, which is higher on the left and lower on the right. The rotation of the rotating roller generates centrifugal force to throw out the water between the particles. Compared with the prior art, this reduces water retention and makes the dewatering effect better. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the embodiments, by Figure 1 and Figure 2A dewatering device for producing high-purity quartz sand is provided, comprising a frame 1, a dewatering cylinder 2 detachably connected to the inner side of the frame 1 by bolts, the dewatering cylinder 2 being inclined from left to right, several crossbars 3 being fixedly connected to the inner side of the dewatering cylinder 2, the distance between two adjacent crossbars 3 being less than the diameter of the quartz sand, an outlet being provided at the bottom end of the dewatering cylinder 2, a feed hopper 4 being fixedly connected to the top end of the dewatering cylinder 2, a rotating shaft 5 being rotatably connected to the inner side of the dewatering cylinder 2, a rotating roller 6 being fixedly connected to the outer side of the rotating shaft 5, several protrusions 11 being provided on the outer side of the rotating roller 6, and a drive mechanism 7 for rotating the rotating shaft 5 being provided on the frame 1.

[0021] With the above setup, after the quartz sand raw material enters the inclined dewatering cylinder 2 from the feed hopper 4, the drive mechanism 7 drives the rotating shaft 5 to rotate, which in turn drives the rotating roller 6 to rotate. Under the rotation of the rotating roller 6, a tumbling motion is generated (the quartz sand is moved by the protrusion 11). The crossbar 3 forms a spaced filter layer, preventing the quartz sand from falling directly. Under the action of gravity, the quartz sand moves slowly along the inclined direction of the dewatering cylinder 2, which is higher on the left and lower on the right. The rotation of the rotating roller 6 generates centrifugal force to throw out the water between the particles. The separated water is continuously discharged through the outlet at the bottom of the dewatering cylinder 2. The dewatered quartz sand is finally discharged from the right end of the dewatering cylinder 2. The inclined structure of the dewatering cylinder 2 forms a gravity flow channel, which, together with the centrifugal dewatering of the rotating roller 6, realizes the simultaneous completion of continuous dewatering and conveying of materials. The spacing design of the crossbar 3 allows for maximum drainage area while blocking the quartz sand, preventing the loss of fine particles. The detachable dewatering cylinder 2 makes it easy to replace the crossbar 3 with different spacings to adapt to the dewatering needs of quartz sand with different particle sizes of 0.2-3mm.

[0022] Reference Figure 1 and Figure 2 The drive mechanism 7 includes a drive motor 71, which is detachably connected to the frame 1 by bolts. A transmission mechanism 72 is fixedly connected to the outer side of the output end of the drive motor 71, and the transmission mechanism 72 is fixedly connected to the outer side of the rotating shaft 5.

[0023] With the above structural configuration, the transmission mechanism 72 can be either a chain and sprocket transmission mechanism or a belt pulley transmission mechanism.

[0024] Reference Figure 1 and Figure 2 The bottom end of the dewatering cylinder 2 is fixedly connected to the water outlet 8, and the bottom surface of the inner cavity of the water outlet 8 is set as an arc surface.

[0025] Through the above structural design, the arc-shaped structure avoids the defect of water accumulation that is easy to occur in the traditional flat-bottom structure, and prevents microorganisms from growing at the bottom of the dewatering cylinder 2 and contaminating the quartz sand.

[0026] Reference Figure 1 and Figure 2 The right end of the dewatering cylinder 2 is fixedly connected to the discharge hopper 9;

[0027] With the above structural design, the flow guide surface radius R=80mm can eliminate the problem of quartz sand accumulating in dead corners caused by traditional straight cylinder discharge.

[0028] Reference Figure 1 and Figure 2 The top of the frame 1 is detachably connected to a rotating seat 10 by bolts, and the rotating shaft 5 is rotatably connected to the inner side of the rotating seat 10.

[0029] Through the above structural design, the rotating seat 10 can play an auxiliary role in bearing weight.
