Description

Technical Field

[0001] This utility model relates to an industrial cleaning auxiliary equipment, specifically a granular material cleaning device. Background Technology

[0002] Granular materials such as silica sand and quartz sand are essential raw materials for high-tech industries such as photovoltaic cells, semiconductors, fiber optic communications, specialty glass, precision instruments, aerospace, and defense. With the rapid development of these high-tech industries, the purity requirements for these materials are becoming increasingly stringent. Granular materials need to be cleaned to remove impurities. In existing technologies, cleaning is initially carried out in a cleaning tank, which consumes a large amount of cleaning fluid and has low cleaning efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a granular material cleaning device to address the shortcomings of existing technologies.

[0004] The technical solution adopted in this utility model is as follows.

[0005] A granular material cleaning device, characterized in that it includes a base, a drum rotating frame, a drum, a cleaning liquid supply device, and a cleaning liquid collection device.

[0006] The left end of the drum is movably connected to a left barrel cover, and a horizontal liquid outlet pipe is coaxially connected to the left side of the left barrel cover; the right end of the drum is connected to a right barrel cover, and a horizontal liquid inlet pipe is coaxially connected to the right side of the right barrel cover; a driven gear plate is connected to the horizontal liquid inlet pipe; a drum bearing is fitted on both the horizontal liquid inlet pipe and the horizontal liquid outlet pipe.

[0007] The two roller bearings of the roller are connected to the roller rotating frame; the left end of the roller rotating frame is hinged to the base.

[0008] The right side of the base is equipped with a drive gear arranged horizontally along the central axis; the drive gear is connected to a gear drive motor mounted on the base or the ground.

[0009] A roller bearing fixing frame is longitudinally provided at both the left and right ends of the top surface of the base. When the roller is placed on the base, each roller bearing is connected to a roller bearing fixing frame, the central axis of the roller is parallel to the ground, and the drive gear meshes with the driven gear plate.

[0010] The right end of the rotating drum frame is hinged to the connecting frame. A lifting device is provided on the right side of the drive gear. The lifting device includes a lifting drive device and a vertically arranged guide rail. The lifting slider is installed on the guide rail and is connected to the lifting drive device. The connecting frame is hinged to the lifting slider. When the lifting slider is at its highest position, the angle between the central axis of the drum and the horizontal plane is an acute angle.

[0011] The horizontal inlet pipe is movably connected to the cleaning fluid supply device; the horizontal outlet pipe is movably connected to the cleaning fluid collection device.

[0012] During cleaning, the drum containing granules is placed on the drum rotating frame, with each drum bearing connected to a drum bearing fixing bracket. A certain amount of cleaning fluid is supplied to the horizontal inlet pipe by the cleaning fluid supply device. The drive gear drives the drum to rotate along its central axis, initiating the cleaning process. After cleaning one end for a period of time, the lifting slider rises, slowly raising the right end of the drum rotating frame. Most of the supernatant of the cleaning fluid inside the drum flows into the cleaning fluid collection device through the horizontal outlet pipe. Then, the lifting slider returns to its original position. At this point, only a small amount of cleaning fluid remains in the lower part of the drum's inner cavity. This process is repeated until cleaning is complete. Finally, the horizontal inlet pipe is disconnected from the cleaning fluid supply device, and the horizontal outlet pipe is disconnected from the cleaning fluid collection device, allowing the drum to be removed. The beneficial effects of this invention are: the connecting frame is hinged to the lifting slider, allowing the drum rotating frame to be raised slowly, facilitating the filtration of the supernatant inside the drum; and a geared drive motor allows the drum to rotate in a horizontal position, achieving cleaning. The horizontal inlet pipe is movably connected to the cleaning fluid supply device; the horizontal outlet pipe is movably connected to the cleaning fluid collection device. The cleaning fluid enters and exits in a single flow, allowing for multiple cleaning cycles in a closed environment. Each injection of cleaning fluid does not exceed half the volume of the drum's inner cavity, enabling multiple cleaning cycles for the material. The cleaning is thorough with minimal cleaning fluid consumption. After cleaning, only a small amount of cleaning fluid remains in the lower part of the drum's inner cavity. The drum is lightweight, making it easy to move and remove the cleaned material.

[0013] As a preferred technical solution, the cleaning fluid supply device is located above the right end of the horizontal inlet pipe; the cleaning fluid collection device is located below the left end of the horizontal outlet pipe.

[0014] As a preferred technical solution, the cleaning fluid supply device includes a first cleaning fluid supply tank and a first supply pipe, the first cleaning fluid supply tank being connected to the first supply pipe; the first supply pipe being connected to the right end of the horizontal inlet pipe via a supply connector; the cleaning fluid collection device includes a first cleaning fluid collection tank and a first drain pipe, the first cleaning fluid collection tank being connected to the first drain pipe; the first drain pipe being connected to the left end of the horizontal outlet pipe via a drain connector.

[0015] As a preferred technical solution, the cleaning fluid supply device includes a second cleaning fluid supply tank, a third cleaning fluid supply tank, and a three-way valve for fluid supply. The second cleaning fluid supply tank is connected to the three-way valve for fluid supply via a second fluid supply pipe, and the third cleaning fluid supply tank is connected to the three-way valve for fluid supply via a third fluid supply pipe. The three-way valve for fluid supply is connected to a fourth fluid supply pipe, and the fourth fluid supply pipe is connected to the right end of the horizontal inlet pipe via a fluid supply connector.

[0016] The cleaning fluid collection device includes a second cleaning fluid collection tank, a third cleaning fluid collection tank, and a drain three-way valve. The second cleaning fluid collection tank is connected to the drain three-way valve via a second drain pipe, and the third cleaning fluid collection tank is connected to the drain three-way valve via a third drain pipe. The drain three-way valve is connected to a fourth drain pipe, and the fourth drain pipe is connected to the left end of the horizontal drain pipe via a drain connector.

[0017] Using this technical solution, different cleaning solutions can be supplied by a second and a third cleaning solution supply tank. For example, one can supply acid and the other can supply deionized water. After acid washing, the material can be washed with water in the granular material cleaning device to obtain high-purity, clean granules. One of the second and third cleaning solution collection tanks collects the acid solution after washing, and the other collects the deionized water after washing.

[0018] As a preferred technical solution, the lower left end of the roller rotating frame is connected to the base via a longitudinal hinge shaft.

[0019] As a preferred technical solution, the lifting device includes a lifting device bracket, a lifting drive device and a guide rail mounted on the lifting device bracket; a horizontal rotating shaft is installed between the lifting device bracket and the base, and a drive gear and a drive wheel are mounted on the horizontal rotating shaft, with the drive wheel connected to a geared drive motor mounted on the ground via a transmission chain.

[0020] With this technical solution, the two ends of the horizontal rotating shaft are connected to the lifting device bracket and the base respectively, making the horizontal rotating shaft relatively stable.

The horizontal inlet pipe 34 is movably connected to the cleaning fluid supply device; the horizontal outlet pipe 32 is movably connected to the cleaning fluid collection device. The cleaning fluid enters and exits in a single flow, allowing for multiple cleaning cycles in a closed environment. Each injection of cleaning fluid does not exceed half the volume of the drum's inner cavity, enabling multiple cleaning cycles that are thorough and consume minimal cleaning fluid. After cleaning, only a small amount of cleaning fluid remains in the lower part of the drum's inner cavity, making it lightweight and easy to move the drum and remove the cleaned material.
