Description

Technical Field

[0001] This utility model relates to the field of water recycling technology, specifically to a water recycling treatment device for the preparation of manufactured sand. Background Technology

[0002] In a water-washed manufactured sand production line, water is mainly used in two stages: Washing: The sand washing machine removes mud, dust, and excess fine powder from the finished sand. Dewatering: After being treated by a dewatering screen, the moisture content of the finished sand is reduced, allowing it to be used directly in concrete construction.

[0003] The washing process of manufactured sand generates a large amount of muddy wastewater, which needs to be treated to achieve resource recovery and emission reduction. A water circulation treatment device is used to remove impurities from the water before reuse in production. However, with long-term use, impurities tend to adhere to the surface of the filter cartridges in existing water circulation treatment equipment. This requires stopping the fluid flow to clean the impurities from the filter cartridge surface, and frequent disassembly of the filter cartridges affects the normal operation of the water circulation treatment. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a water recycling treatment device for the preparation of manufactured sand, thereby solving the water recycling problem.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A water recycling treatment device for manufactured sand preparation, comprising: Filter; The water inlet is located at the bottom of the filter; The flow guiding channel is a set, which is opened at the bottom of the filter and connected to the water inlet; The filter cartridges are a set, installed at an angle on both sides inside the filter. One drive unit, consisting of a set, is installed on both sides of the filter and is used to drive a set of filter cartridges to rotate; The impurity discharge channel is located inside the filter and at the bottom of a set of filter cartridges; The waste discharge pipe is inserted at the front end of the filter and is connected to the waste discharge channel; The water outlet is located at the top of the filter and has an internal flow regulating mechanism; The differential pressure gauge is installed at the rear end of the filter and is connected to the inlet and outlet pipes respectively.

[0006] Furthermore, the flow regulating mechanism includes a drive shaft that is movably inserted into the filter. The rear end of the drive shaft is connected to a connecting rod one, and the front end of the connecting rod one is hinged to a connecting rod two. A guide sealing ring is installed inside the water outlet, and a regulating valve is movably inserted inside the guide sealing ring. The rear end of the regulating valve is hinged to the connecting rod two, and several water outlet holes are evenly opened on the outer surface of the front end of the regulating valve.

[0007] Furthermore, the front end of the filter housing has a second drive device installed on its upper end. The rotating end of the second drive device is movably inserted into the housing via a worm gear, and the front end of the drive shaft meshes with the worm gear via a worm wheel. The second drive device is a stepper motor. The second drive device drives the worm wheel to rotate via the worm gear, and pulls the position of the regulating valve through connecting rod one and connecting rod two. The regulating valve is cylindrical, and several water outlet holes are evenly opened on the outer surface of the front end. The filtered water can be discharged through several water outlet holes. By adjusting the position of the regulating valve, the flow rate of the water flowing out of the outlet can be adjusted, which is convenient for subsequent sand washing.

[0008] Furthermore, a set of cleaning brushes that fit against the filter cartridge are fixedly installed on the inner wall of the filter, and cleaning ports corresponding to the cleaning brushes are opened on both sides of the filter. When the filter cartridge rotates, the cleaning effect can be improved by cooperating with the cleaning brushes, and the cleaning ports can be used to clean and replace the cleaning brushes.

[0009] Furthermore, the top of each set of filter cartridges is connected to the inner wall of the filter via a sealing bearing ring, which facilitates the filter cartridges to filter impurities in muddy wastewater.

[0010] Furthermore, a manual control valve is installed on the discharge pipe to facilitate manual opening or closing of the discharge pipe.

[0011] This utility model provides a water recycling treatment device for manufactured sand preparation, which has the following beneficial effects: muddy wastewater flows into the filter through the inlet, and a set of filter cartridges can filter impurities in the wastewater. The filtered water is discharged through the outlet and reused in production, realizing resource recovery and emission reduction. Impurities are trapped on the surface of the filter cartridges. When the differential pressure gauge detects a large differential pressure between the inlet and outlet pipelines, the impurity discharge pipe is opened, and the drive device drives the filter cartridges to rotate. Impurities are discharged through the impurity discharge pipe, realizing the self-cleaning of the filter cartridges. There is no need to stop the fluid flow, ensuring the normal use of water recycling treatment. Attached Figure Description
