Description

Technical Field

[0001] The utility model relates to the technical field of oily wastewater recycling devices, in particular to an oily wastewater recycling device. Background Art

[0002] The oily wastewater recovery device uses physical principles to efficiently separate the grease in the wastewater, and guides the separated grease to the collection device through a specific outlet pipe. The treated wastewater can be recycled or discharged in compliance with regulations. This device provides an effective means for the treatment of oily wastewater, but the existing device is driven by multiple motors to purify the oily wastewater. There is still room for improvement in resource utilization, and the waste grease removal mechanism needs to be regularly maintained by staff, otherwise the cleaning of the oily wastewater will not be thorough enough, affecting the cleaning effect of the waste grease. Utility Model Content

[0003] The purpose of the utility model is to provide an oily wastewater recycling device in order to solve the above-mentioned problem. The power conversion mechanism utilizes the force of water flow, and drives the guide mechanism through the second synchronous belt to scrape off the waste grease floating on the water surface. When the scraper in the guide mechanism enters the cleaning mechanism, it will push the ball in the cleaning mechanism, thereby causing the brush to clean one side of the scraper.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] An oily wastewater recycling device comprises: a wastewater treatment tank, a power conversion mechanism and a guide mechanism, wherein the guide mechanism and the power conversion mechanism are both arranged on the front side of the inner wall of the wastewater treatment tank;

[0006] The power conversion mechanism comprises a first rotating shaft, three first support plates are arranged on the front and rear sides of the first rotating shaft, a support rod is fixedly arranged on the front side of the first support plate, a semicircular groove is fixedly arranged on the front side of the support rod, and drainage ports are arranged on both the front and rear sides of the semicircular groove;

[0007] The guiding mechanism comprises two second rotating shafts, a first synchronous belt is arranged between the outer circles of the two second rotating shafts, and a plurality of scrapers are fixedly arranged on the rear side of the first synchronous belt.

[0008] Furthermore, a waste removal mechanism is provided on the rear side of the inner wall of the wastewater treatment box, and a cleaning mechanism is provided on one side of the waste removal mechanism.

[0009] Furthermore, the cleaning mechanism comprises a collecting plate, a second supporting plate is fixedly provided on a side of the collecting plate away from the waste discharging mechanism, and a first torsion spring gear and a second torsion spring gear are longitudinally rotatably provided on the rear side of the second supporting plate.

[0010] Furthermore, a bent rod is provided on the outer circle of the first torsion spring gear, a ball is fixedly provided on the side of the bent rod close to the waste removal mechanism, a third rotating shaft is fixedly provided on the rear side of the second torsion spring gear, a support handle is fixedly provided on the shaft body of the third rotating shaft, and a brush is provided on the top side of the support handle.

[0011] Furthermore, the waste removal mechanism includes a motor frame, a collecting bent plate is fixedly arranged at the lower front side of the motor frame, and a dragon roller is arranged at the front side of the motor frame and connected to the motor.

[0012] Furthermore, a waste treatment mechanism is arranged at the front side of the wastewater treatment box, and the waste treatment mechanism includes a waste residue collection box, blocking plates are fixedly arranged on both sides of the top side of the waste residue collection box, and a discharge outlet is slidably arranged at the front side of the waste residue collection box.

[0013] Furthermore, the power conversion mechanism and the guide mechanism are directly provided with a second synchronous belt.

[0014] Furthermore, a wastewater outlet is provided on one side of the wastewater treatment tank, a water storage tank is provided on the other side, and an air flotation device is provided on the top side of the wastewater treatment tank.

[0015] With the above structure, after the oily wastewater flows out from the wastewater outlet, it enters the wastewater treatment box, and then flows into the groove of the air flotation device. The air flotation device generates bubbles to wrap the grease and waste particles in the oily wastewater. The bubbles bring the grease and waste particles out of the horizontal plane, so that the grease and waste particles remain on the horizontal plane. Then, the scraper in the guide mechanism scrapes the grease from the horizontal plane into the waste removal mechanism. The water after the grease is removed flows out from the bottom into the water storage tank. When it flows into the middle of the water storage tank, it pushes the power conversion mechanism, so that the power conversion mechanism drives the guide mechanism through the second synchronous belt, so as to clean the wastewater at all times. When the scraper moves with the first synchronous belt, it will contact the ball in the cleaning mechanism, and the scraper pushes the ball to one side. The ball rotates the first torsion spring gear through the bent rod, and the first torsion spring gear rotates with the second torsion spring gear. The first torsion spring gear and the second torsion spring gear rotate relative to each other through meshing. At this time, the third rotating shaft and the support handle on the rear side of the second torsion spring gear will rotate in the direction of the scraper movement, and the brush on the support handle will clean one side of the scraper.

[0016] In summary, the beneficial effects of the utility model are: the power conversion mechanism provides power to the purified wastewater, drives the guide mechanism to clean the wastewater, and the guide mechanism also drives the cleaning mechanism to clean the guide mechanism itself, thereby improving resource utilization;

[0017] The waste grease sent by the scraper in the guiding mechanism is collected by the waste discharge mechanism and transported to the waste treatment mechanism for centralized treatment of the waste grease. The cleaning mechanism itself also has a collecting plate that can guide the waste grease, and cleans up the waste grease stuck on the guiding mechanism after the guiding mechanism is cleaned, so that the guiding mechanism maintains a better cleaning effect.
