Description

Technical Field

[0001] This utility model relates to the field of electrode paste production technology, and in particular to a spray water recovery device for electrode paste production. Background Technology

[0002] In the production of electrode paste (carbon electrodes), the electrodes, after being formed at high temperatures, need to be rapidly cooled through a spray water system. During the spraying process, the water flow, upon contact with the electrode surface, carries a large amount of carbon powder, asphalt volatiles, and heavy metal impurities, forming industrial wastewater with high turbidity and high COD (chemical oxygen demand). Traditional treatment methods mostly involve direct discharge or simple sedimentation, which not only wastes water resources but may also pose environmental risks due to excessive pollutants. Therefore, spray water recovery equipment for electrode paste production has emerged on the market.

[0003] Existing spray water recovery equipment typically uses filter screens to filter spray water. However, during the long-term filtration process, impurities in the spray water gradually accumulate on the filter screen and clog the filter pores. Therefore, there is a need for a spray water recovery device for electrode paste production that can automatically clean the impurities on the filter screen. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a spray water recovery device for electrode paste production. The device utilizes a water collection tank to drive a filter tank that sequentially passes directly below the spray water outlet. The filter screen within the filter tank filters the spray water. The water collection tank causes the filter screen to slide on a limiting rod. When the filter screen passes the break, it rotates under gravity, automatically opening the bottom of the filter tank and discharging the filtered impurities. This device is simple, efficient, safe, reliable, and easy to operate.

[0005] This utility model is achieved through the following technical solution: A spray water recovery device for electrode paste production is provided, including a support frame; an annular water collection tank is mounted on the support frame, and the water collection tank is located directly below the spray water outlet; the water collection tank is divided into several filter tanks arranged around the axis of the water collection tank by baffles, and filter screens are hinged to the bottom of the filter tanks; a limiting rod extending along the movement trajectory of the filter tanks is provided below the water collection tank, the movement trajectory of the filter screens intersects with the limiting rod, and a cut larger than the size of the filter screen is provided on the limiting rod; the water collection tank drives the filter tanks to pass sequentially below the spray water outlet, and the filter screens in the filter tanks filter the spray water; the water collection tank drives the filter screens to slide on the limiting rod, and when the filter screens pass the cut, they rotate under the action of gravity, the bottom of the filter tanks automatically opens, and the impurities filtered out by the filter screens are automatically discharged.

[0006] As an optimization, a cleaning brush is hinged inside the filter tank, and the hinge axis of the cleaning brush is parallel to the hinge axis of the filter screen. The cleaning brush is located at the top of the hinge end of the filter screen, and the hinge end of the cleaning brush is located on the side of the filter tank away from the hinge end of the filter screen. When the filter screen rotates, the cleaning brush rotates on the filter tank under the action of gravity and slides along the filter screen. The cleaning brush cleans the top of the filter screen and scrapes away the impurities attached to the top of the filter screen.

[0007] As an optimization, a slide rail is fixed on the filter screen, the axis of the slide rail is perpendicular to the hinge axis of the filter screen, and the cleaning brush is slidably installed in the slide rail; the slide rail limits the cleaning brush to prevent the cleaning brush from falling off the filter screen.

[0008] As an optimization, the cleaning brush is hinged to the filter tank via a connecting rod, and the cleaning end of the cleaning brush extends along the filter screen; by rotating the cleaning brush on the connecting rod, it is ensured that the cleaning end of the cleaning brush is always in contact with the filter screen.

[0009] As an optimization, a diversion plate is fixed on the side of the baffle. The diversion plate is located directly above the hinge end of the filter screen, and the movement trajectory of the cleaning brush passes directly below the diversion plate. The movement trajectory of the cleaning brush covered by the diversion plate is larger than the size of the cleaning brush. The diversion plate prevents the sprayed water from falling directly between the cleaning brush and the hinge end of the filter screen, increasing the time for impurities to accumulate between the cleaning brush and the hinge end of the filter screen.

[0010] As an optimization, a diversion groove is provided on the diversion plate, with the bottom of the diversion groove away from the slide rail; the diversion groove guides the spray water on the diversion plate, preventing the spray water from falling directly onto the slide rail and increasing the time for impurities to accumulate on the slide rail.

[0011] As an optimization, the top of the baffle is located below the top of the water collection tank, and the spray water outlet is located between the top of the baffle and the top of the water collection tank; the drop between the baffle and the water collection tank prevents the spray water from falling outside the water collection tank.

[0012] As an optimization, the top of the baffle is provided with an inclined surface that faces the filter tank; the inclined surface prevents impurities from accumulating on the top of the baffle.

[0013] The beneficial effects of this utility model are as follows: the water collection tank drives the filter tank to pass directly below the spray water outlet, and the filter screen in the filter tank filters the spray water; the water collection tank drives the filter screen to slide on the limiting rod, and when the filter screen passes the break, it rotates under the action of gravity, the bottom of the filter tank opens automatically, and the impurities filtered out of the filter screen are automatically discharged; the sliding rail limits the cleaning brush to prevent the cleaning brush from detaching from the filter screen. When the filter screen rotates, the cleaning brush rotates on the filter tank under the action of gravity and slides along the filter screen, cleaning the top of the filter screen and scraping away the impurities attached to the top of the filter screen; the cleaning brush rotates on the connecting rod to ensure that the cleaning end of the cleaning brush is always in contact with the filter screen; the diversion plate prevents the spray water from falling directly between the hinge end of the cleaning brush and the filter screen, increasing the time for impurities to accumulate between the hinge end of the cleaning brush and the filter screen.
