By adopting corresponding technical means, valuable metals can be extracted from fine sand to reduce the impact on the environment and realize the reuse of resources. Referring to the utility model of a dry mortar dust recovery device with the authorization announcement CN219355699U, it can be seen that the above scheme provides a structure for collecting fine sand by using a screen to sieve after spraying clean water to settle the dust. However, there is a problem that the mud mixed in the fine sand cannot be separated, resulting in a large amount of impurities in the collected fine sand and a high water content in the collected fine sand.

[0020] The above description of the main component symbols is combined with the accompanying drawings and specific implementation methods to further illustrate the present invention in detail. DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1-4 This embodiment provides a fine sand recovery device, including a filtering mechanism 1, a cleaning mechanism 3 fixedly connected below the filtering mechanism 1, a collecting mechanism 4 fixedly connected below the cleaning mechanism 3, and a control mechanism 2 located between the filtering mechanism 1, the cleaning mechanism 3 and the collecting mechanism 4.

[0023] Filter mechanism 1 includes a housing 112, a filter screen 15 mounted within the housing 112, a feed pipe 13 and a nozzle 11 fixedly connected to the housing 112, and an air pump 14 mounted on the feed pipe 13. The feed pipe 13 and nozzle 11 are located above the filter screen 15. The air pump 14 draws fine sand containing mud into the housing 112 through the feed pipe 13. The nozzle 11 sprays lime water, which converts the mud in the fine sand into larger particles and is filtered by the filter screen 15.

[0024] The cleaning mechanism 3 includes a material pipe 33 fixedly connected to the housing 112. The feed end of the material pipe 33 vertically extends through the upper portion of the cleaning pipe 31, and the discharge end of the material pipe 33 vertically extends through the lower portion of the cleaning pipe 31. The material pipe 33 is positioned horizontally within the cleaning pipe 31, and a plurality of holes are provided in the middle of the material pipe 33 for the passage of water. A spiral fin 32 is horizontally mounted within the material pipe 33. A bevel gear I36 is fixedly connected to the opposite side of the spiral fin 32. A bevel gear II37 meshes with the bevel gear I36. A transmission rod 38 is fixedly connected to the bevel gear II37 at one end. A motor 35 is connected to the other end of the transmission rod 38. The cleaning pipe 31 is covered by the material pipe 33. A waterproof ring 34 is mounted on the transmission rod 38 and contacts the cleaning pipe 31. In order to ensure that the transmission rod 38 can rotate without causing water leakage in the device, the waterproof ring 34 in this embodiment is illustrated by using silicone as an example. In other embodiments, rubber or other materials that can undergo a certain degree of deformation and are waterproof can also be used, which will not be elaborated here.

[0025] To facilitate future maintenance and prevent damage to the motor 35 in humid environments, the motor 35 is located outside the cleaning pipe 31. The transmission rod 38 extends through the cleaning pipe 31 and the material pipe 33. When wet, fine sand becomes viscous and difficult to flow. Using a vertical pipe or a pipe with a large inclination would result in insufficient cleaning time. Therefore, in this embodiment, spiral fins 32 are used to transport the soaked fine sand forward at a steady rate while ensuring that the fine sand, which is impregnated with limewater and other meltwater impurities, comes into full contact with the water, resulting in a more effective flushing effect. A stopper is provided on one side of the spiral fin 32 to prevent it from shifting during rotation.

[0026] The collection mechanism 4 comprises a housing 1142 connected to the material pipe 33, an exhaust pipe 41 fixedly attached to the housing 1142, and a heating blanket 43 mounted at the bottom of the inner cavity of the housing 1142. A door is hingedly connected to the housing 1142, and the door can open and close at an angle ranging from 0 to 180 degrees. The control mechanism 2 includes a solenoid valve 121 mounted at the upper end of the material pipe 33 and a solenoid valve 122 mounted at the lower end of the material pipe 33.

[0027] Solenoid valve I21 closes, and suction pump 14 draws the muddy fine sand into housing I12. Nozzle 11 sprays limewater, and the mud in the fine sand is filtered by filter screen 15. Then, solenoid valve I21 opens, solenoid valve II22 closes, and the fine sand flows into material pipe 33. Solenoid valve I21 closes, and clean water flows into cleaning pipe 31. Motor 35 drives spiral fin 32 to rotate. After the water in cleaning pipe 31 has flowed out, solenoid valve II22 opens. After the damp fine sand flows into housing II42, heating blanket 43 dries the fine sand, and the water vapor is discharged through exhaust pipe 41. Solenoid valve II22 closes, solenoid valve I21 opens, and the above process repeats. To remove the fine sand from housing II42, first close solenoid valve II22, then open the housing door on housing II42 to remove the fine sand. After closing the cabinet door, the equipment can be operated again.

[0028] In summary, the fine sand recovery device of this embodiment has the following advantages: the recovery device of the present invention can obtain dry fine sand with less impurities through filtering, washing and drying structures, and the obtained product is of higher quality.

[0029] The naming of the various components involved is based on the functions described in the specification, and is not limited to the specific nouns used in the present invention. Those skilled in the art may also choose other nouns to describe the names of the various components of the present invention.
