Quartz sand washing and impurity removal dewatering device

Abstract

This utility model discloses a dewatering device for quartz sand after washing and impurity removal, including a dewatering component, a feeding component, and a discharging component. The feeding component is located on one side of the dewatering component, and the discharging component is located at the lower end of the dewatering component. The dewatering component includes a centrifugal dewatering chamber; a screen tube is installed inside the centrifugal dewatering chamber; a drive shaft is installed inside the screen tube; and quartz sand scrapers are installed outside the drive shaft. This utility model uses a servo motor to drive the drive shaft to rotate. The rotating drive shaft drives the feeding screw and the quartz sand scrapers to rotate. The rotating feeding screw spirally pushes the material, pushing the material fed into the hopper into the screen tube. Then, the high-speed rotating quartz sand scrapers centrifugally rotate the quartz sand, using centrifugal force to throw the water contained in the quartz sand out of the screen tube, thereby achieving the separation of quartz sand and water. As the quartz sand material continues to advance, the water-separated quartz sand material inside the screen tube is discharged and collected through the sand discharge pipe.

Description

Technical Field

[0001] This utility model relates to the field of quartz sand dewatering technology, and in particular to a device for dewatering quartz sand after washing and removing impurities. Background Technology

[0002] Quartz sand, a key raw material in industries such as glass manufacturing and photovoltaic panels, needs to be washed to remove impurities such as clay and dust to improve its purity. However, after washing, quartz sand has a high water content. If it directly enters the drying process, it will significantly increase energy consumption and processing time. Therefore, dehydration has become the core step after the washing process. Vibration dehydration devices have become the mainstream equipment and are widely used in small and medium-sized quartz sand processing production lines because of their simple structure and high processing efficiency. They use a vibrating motor to drive the screen to vibrate at high frequency and use the inertial difference between quartz sand particles and water to achieve solid-liquid separation.

[0003] When the screen vibrates, the quartz sand moves along the screen surface under the action of gravity and vibration. Water seeps out through the screen pores, but the quartz sand will form a certain thickness of accumulation layer on the screen surface. The upper layer of particles is blocked by the lower layer of particles, and the probability of contact with the screen is low. Water is difficult to quickly penetrate to the screen surface. Moreover, during the vibration process, the upper layer of quartz sand is prone to "clumping" due to the vibration force. The gaps between the particles are filled with water, making it difficult to be discharged in time through screening. At the same time, when the processing volume is large, the increased load on the screen surface leads to an increase in the thickness of the accumulation layer and a longer separation path for the upper layer of water. Ultimately, the dehydrated quartz sand still contains a large amount of water, which cannot meet the requirements of the subsequent drying process and requires additional drying costs. Utility Model Content

[0004] In order to overcome the problem that existing quartz sand washing and impurity removal vibration dewatering devices rely on vibration screening for dewatering, making it difficult to separate the water in the upper layer of quartz sand in time, resulting in the quartz sand still containing a large amount of water after vibration dewatering, this utility model provides a quartz sand washing and impurity removal dewatering device.

[0005] The technical solution is as follows: A dewatering device for quartz sand after washing and impurity removal includes a dewatering component, a feeding component, and a discharging component; a feeding component is provided on one side of the dewatering component; a discharging component is provided at the lower end of the dewatering component; the dewatering component includes a centrifugal dewatering chamber; a screen tube is provided inside the centrifugal dewatering chamber, and the screen tube is bolted to the inner wall of the centrifugal dewatering chamber; a drive shaft is provided inside the screen tube; a quartz sand scraper is provided outside the drive shaft, and the quartz sand scraper is located inside the screen tube, and the quartz sand scraper is fixedly connected to the drive shaft, and the quartz sand scraper is in contact with the inner wall of the screen tube.

[0006] Furthermore, a feeding pipe is provided on one side of the centrifugal dehydration chamber, and the feeding pipe is integrally formed with the centrifugal dehydration chamber; a feeding screw is provided inside the feeding pipe, and the feeding screw is integrally formed with the drive shaft.

[0007] Furthermore, a servo motor is installed below the feeding tube, and the output end of the servo motor is connected to the feeding screw via a synchronous belt drive.

[0008] Furthermore, a hopper is provided at the upper end of the feeding pipe, and the hopper is connected to the interior of the feeding pipe.

[0009] Furthermore, the mesh size of the screen tube is smaller than the diameter of the quartz sand; the upper end face of the centrifugal dewatering chamber is equipped with a maintenance sealing cover, and the maintenance sealing cover is hinged to the centrifugal dewatering chamber.

[0010] Furthermore, the discharge assembly includes a drainage hopper and a sand discharge pipe; the lower end of the centrifugal dewatering chamber is provided with a drainage hopper, and the drainage hopper and the centrifugal dewatering chamber are integrally formed.

[0011] Furthermore, a sand discharge pipe is provided on one side of the drainage hopper, and the sand discharge pipe is integrally formed with the centrifugal dewatering chamber, and the sand discharge pipe is located at the end away from the feeding pipe.

[0012] The beneficial effects are as follows: In the entire process of separating quartz sand and water, the servo motor first provides the power source to drive the transmission shaft to rotate. This rotational transmission process forms the basis for all subsequent processing actions, enabling the transmission shaft to simultaneously drive the feeding screw and the quartz sand scraper to operate synchronously. The rotating feeding screw generates a continuous pushing force through its spiral structure, steadily pushing the quartz sand material pre-loaded into the hopper forward. During this pushing process, the material gradually moves along a predetermined path and is ultimately precisely conveyed into the inside of the screen tube, preparing for subsequent separation operations. When the material enters the screen... After the tube, the high-speed rotating quartz sand scraper plays a key role. It drives the quartz sand to undergo violent centrifugal rotation. Under the strong action of centrifugal force, the water contained in the quartz sand is effectively separated from the quartz sand particles and thrown out of the screen tube through the screen holes. Thus, the separation and processing function of quartz sand and water is successfully realized. As the feeding screw continuously pushes the quartz sand material, the quartz sand material that has completed water separation inside the screen tube continues to move forward under the push of the subsequent material and is finally discharged smoothly from the sand discharge pipe for centralized collection and processing. The entire separation and processing process is thus completed in one cycle.

[0013] By setting up a drainage hopper, the centrifugal dewatering chamber intercepts the water thrown out from the screen tube. The water on the inner wall of the centrifugal dewatering chamber falls down along the drainage hopper due to gravity, thereby realizing the function of collecting water from the quartz sand and reducing maintenance difficulty.

The dewatering component 1 includes a centrifugal dewatering chamber 101. A screen tube 104 is provided inside the centrifugal dewatering chamber 101, and the screen tube 104 is bolted to the inner wall of the centrifugal dewatering chamber 101. A drive shaft 102 is provided inside the screen tube 104. A quartz sand scraper 103 is provided outside the drive shaft 102, and the quartz sand scraper 103 is located inside the screen tube 104. The quartz sand scraper 103 is fixedly connected to the drive shaft 102, and the quartz sand scraper 103 is in contact with the inner wall of the screen tube 104.

[0023] A feeding pipe 201 is provided on one side of the centrifugal dehydration chamber 101, and the feeding pipe 201 is integrally formed with the centrifugal dehydration chamber 101; a feeding screw 203 is provided inside the feeding pipe 201, and the feeding screw 203 is integrally formed with the drive shaft 102.

[0024] A servo motor 204 is installed below the feeding pipe 201, and the output end of the servo motor 204 is connected to the feeding screw 203 via a synchronous belt drive.

[0025] A hopper 202 is provided at the upper end of the feeding pipe 201, and the hopper 202 is connected to the interior of the feeding pipe 201.

[0026] The mesh size of the screen tube 104 is smaller than the diameter of the quartz sand; the upper end face of the centrifugal dewatering chamber 101 is provided with a maintenance sealing cover 105, and the maintenance sealing cover 105 is hinged to the centrifugal dewatering chamber 101.

[0027] In the entire process of separating quartz sand and water, the servo motor 204 first provides the power source to drive the drive shaft 102 to rotate. This rotational transmission process forms the basis for all subsequent processing actions, enabling the drive shaft 102 to simultaneously drive the feeding screw 203 and the quartz sand scraper 103 to operate synchronously. The rotating feeding screw 203 generates a continuous pushing force through its spiral structure, steadily pushing the quartz sand material pre-loaded into the hopper 202 forward. During this pushing process, the material gradually moves along a predetermined path and is finally precisely conveyed into the screen tube 104, preparing for subsequent separation operations. When the material enters the screen tube 104... Then, the high-speed rotating quartz sand scraper 103 plays a key role. It drives the quartz sand to rotate violently by centrifugation. Under the strong action of centrifugal force, the water contained in the quartz sand is effectively separated from the quartz sand particles and thrown out of the screen tube 104 through the screen holes. Thus, the separation and processing function of quartz sand and water is successfully realized. As the feeding screw 203 continuously pushes the quartz sand material, the quartz sand material that has completed the water separation inside the screen tube 104 continues to move forward under the push of the subsequent material and is finally discharged smoothly from the sand discharge pipe 302 for centralized collection and processing. The entire separation and processing process is thus completed in one cycle.

[0031] By setting up the drainage bucket 301, the centrifugal dewatering chamber 101 intercepts the water thrown out from the screen tube 104. The water on the inner wall of the centrifugal dewatering chamber 101 falls down along the drainage bucket 301 due to gravity, thereby realizing the function of collecting water from the quartz sand and reducing maintenance difficulty.
