[0001] The utility model relates to the technical field of manufactured sand production and processing, in particular to a water circulation utilization device for wet manufactured sand production. Background Technique

[0002] When preparing manufactured sand, first, stones need to be conveyed into a crusher for crushing, and then the crushed stone particles are transported to a screening machine through a conveyor belt. The vibrating screen on the screening machine is used to screen them, and the stone particles that meet the regulations are screened into a sand washer, and the stone particles are washed with water through the sand washer to obtain manufactured sand;

[0003] When the existing water circulation utilization device for wet manufactured sand production is in use, the wastewater after sand washing is filtered through a filtering mechanism to filter the sand bodies and sundries in the wastewater, so that the water body is cleaned and then conveyed into the sand washer for reuse, so as to achieve the effect of saving water resources. However, during the filtering process of the wastewater, the filtered sundries and fine sand will accumulate on the surface of the filtering mechanism, which not only easily blocks the filtering mechanism and reduces the filtering effect, but also needs to be manually shut down and cleaned later, which is time-consuming and laborious and also reduces the work efficiency. For this reason, we propose a water circulation utilization device for wet manufactured sand production. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a water circulation utilization device for wet manufactured sand production, which can effectively solve the problems in the background technique.

One side of the upper surface of the filtering tank is provided with a liquid delivery port. The top end of the liquid delivery port is interconnected with a liquid suction pipe, and the end of the liquid suction pipe extends into the interior of the sand washer. A liquid suction pump is provided at the end of the liquid suction pipe. The bottom end of the liquid delivery port is fixedly connected with a liquid injection pipe. The top end of the filtering tank is inlaid with a motor, and the power output end of the motor penetrates through the top end of the filtering tank and extends to the top end of the inner cavity of the filtering tank. The power output end of the motor is detachably connected with a filtering cylinder. The bottom end of the filtering cylinder is interconnected with a discharge assembly. The top end of the discharge assembly is detachably connected with a scraping frame, and the scraping frame extends into the filtering cylinder, and the edge of the scraping frame is attached to the inner side wall of the filtering cylinder.

[0006] Preferably, the discharge assembly includes a drain pipe detachably connected to the bottom end of the filtering tank, and the drain pipe is interconnected with the bottom end of the filtering tank. A waste discharge pipe is vertically and fixedly connected to the center position of the top end of the drain pipe and penetrates through the bottom end of the drain pipe and extends to the outside of the bottom end of the drain pipe.

[0007] Preferably, a connecting shaft is fixedly connected to the top end of the impurity discharge pipe, and the impurity discharge pipe is rotatably connected to the bottom end of the filter cylinder through the connecting shaft. A fixing rod for fixing the scraping rack is fixedly connected to the central position of the impurity discharge pipe.

[0008] Preferably, a bottom plate is fixedly connected to the bottom end of the sand washer.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By setting the filter tank, motor, filter cylinder and scraping rack to cooperate with each other, the waste water after sand washing is sucked by the water suction pump provided in the water suction and conveyed into the filter cylinder inside the filter tank through the water suction pipe. The waste water is filtered by the filter cylinder, and while filtering, the motor drives the filter cylinder to rotate to achieve a centrifugal effect, so that the water body quickly passes through the filter cylinder and is thrown into the inner cavity of the filter tank, and the filtered sand and sundries remain in the filter cylinder, thereby achieving the rapid filtering effect of the sand washing waste water. During the rotation of the filter cylinder, the inner wall will scrape against the scraping rack, so as to avoid the problem that sand or sundries adhere to the inner wall of the filter cylinder and cause blockage of the filter cylinder while centrifugally filtering. Compared with the traditional filtering method, the filtering efficiency can be effectively improved, and then the recycling treatment efficiency of the waste water can be improved.

[0014] 2. By setting the filter tank, filter cylinder, discharge assembly and water guide pipe to cooperate with each other, during the filtering process, the filtered water body will flow down along the inner wall of the filter tank, flow out through the drain pipe and enter the sand washer through the water guide pipe for recycling, avoiding waste of water resources.

The power output end of the motor 5 is detachably connected with a filter cartridge 11. The bottom end of the filter cartridge 11 is interconnected with a discharging assembly 8. The top end of the discharging assembly 8 is detachably connected with a scraping frame 13, and the scraping frame 13 extends into the filter cartridge 11, and the edge of the scraping frame 13 is in contact with the inner side wall of the filter cartridge 11; the waste water is filtered by the filter cartridge 11, and while filtering, the motor 5 is used to drive the filter cartridge 11 to rotate, so as to achieve a centrifugal effect, so that the water body quickly passes through the filter cartridge 11 and is thrown into the inner cavity of the filter tank 4, and the filtered sand and impurities remain in the filter cartridge 11, so as to achieve a rapid filtering effect of the sand washing waste water, and during the rotation of the filter cartridge 11, the inner wall will scrape against the scraping frame 13, so as to avoid the problem that sand or impurities adhere to the inner wall of the filter cartridge 11 and cause blockage of the filter cartridge 11 while centrifugally filtering.

[0022] Among them, the discharging component 8 includes a drain pipe 802 detachably connected to the bottom end of the filter tank 4, and the drain pipe 802 is interconnected with the bottom end of the filter tank 4. At the center position of the top end of the drain pipe 802, a waste discharging pipe 801 is vertically and fixedly connected, passing through the bottom end of the drain pipe 802 and extending to the outside of the bottom end of the drain pipe 802. The top end of the waste discharging pipe 801 is fixedly connected with a connecting shaft 12, and the waste discharging pipe 801 is rotationally connected to the bottom end of the filter cylinder 11 through the connecting shaft 12. A fixing rod 14 for fixing the scraping rack 13 is fixedly connected at the center position of the waste discharging pipe 801. During the filtering process, the water body thrown out will flow down along the inner wall of the filter tank 4, flow out through the drain pipe 802 and enter the sand washer 2 along the water guide pipe for recycling, avoiding waste of water resources. When discharging impurities, only need to open the valve at the bottom end of the waste discharging pipe 801, then the impurities and sand can be discharged outwards along the waste discharging pipe 801, without manual shutdown for manual cleaning, saving time and effort and effectively improving the work efficiency.

[0023] Among them, the bottom end of the sand washer 2 is fixedly connected with a bottom plate 1.
