The working procedure of this embodiment is: before use, the power supply for starting the cooling water circulation system is firstly connected, the semiconductor refrigerating piece 48 starts to work after the power supply is connected, the cooling surface of the semiconductor refrigerating piece 48 is attached to the heat conducting piece 49 arranged on the cooling water tank 45, the cooling agent in the cooling water tank 45 is cooled through the heat conducting piece 49, the radiator 47 is attached to the heating surface of the semiconductor refrigerating piece 48, and the cooling surface of the semiconductor refrigerating piece 48 is cooled through the fan on the radiator 47.
Then, the circulating pump 46 is started, the cooled coolant in the cooling water tank 45 is pumped out and sent into the cooling pipe 25 after the circulating pump 46 works, the coolant can flow into the communicating vessel 26 through the cooling pipe 25, the coolant can flow into the guide pipe 34 in the rotating shaft 27 through the communicating vessel 26, the rotating shaft 27 and the viscous oil disc 29 fixed on the rotating shaft 27 are cooled, the coolant flowing into the guide pipe 34 can flow back into the communicating vessel 26 from the other end of the guide pipe 34, and flows back into the cooling water tank 45 again through the return pipe 24 on the communicating vessel 26 to form circulation, then the motor 28 is started again, and the rotating shaft 27 and the viscous oil disc 29 on the rotating shaft 27 are driven to rotate through the motor 28.
It should be noted that when the oil pan 29 is rotated, since the oil scraping plate 30 is inclined, the lower side protrudes from the oil outlet 39, so that it is ensured that the grease separated from the sewage by the oil pan 29 is scraped off by the oil scraping plate 30 and directly discharged out of the apparatus through the oil scraping plate 30.
At this time, sewage flows into the slag removing bin 3 of the box body 1 through the water inlet pipe 22, the sewage passes through the filter plate 12 after entering the slag removing bin 3, the large sundries in the sewage can be filtered out by the filter plate 12 when passing through the filter plate 12, the filtered sewage can be blocked and gathered by the guide cover 17 below the filter plate 12 after passing through the filter plate 12, and flows out from the water outlet end of the guide cover 17 under the guide of the guide cover 17, the preliminarily filtered sewage flowing out from the water outlet end of the guide cover 17 can fall on the impeller 18, the impeller 18 starts to rotate under the impact of backflow, the impeller 18 drives the connected driving belt pulley 19 to rotate after rotating, the driven belt pulley 20 is driven to rotate after driving to drive the driven belt pulley 20 to rotate, the driving chain wheel 8 in the mounting groove 6 is driven to rotate after the driven belt pulley 20 rotates, the driving sprocket 8 rotates and then cooperates with the driven sprocket 9 to enable the chain 10 sleeved on the driving sprocket 8 and the driven sprocket 9 to rotate, the chain 10 rotates and then drives the sliding frame 7 installed in the installation groove 6 to slide along the installation groove 6 through the driving block 11 on the chain 10, the sliding frame 7 drives the slag scraping plate 13 to move along with the sliding frame 7 through the sliding block 14 when sliding along the installation groove 6, and the sliding frame 7 drives the slag scraping plate 13 to move from the lower side to the higher side on the filtering plate 12 because the installation height of one side of the filtering plate 12 is higher than the other side, the spring 15 above the sliding block 14 is compressed when the sliding frame 7 drives the slag scraping plate 13 to move from the lower side to the higher side on the filtering plate 12, so that the bottom of the slag scraping plate 13 can always keep a sliding fit state with the filtering plate 12, impurities filtered out from the filtering plate 12 can be scraped onto the supporting plate 16 through the movement of the slag scraping plate 13, and finally the impurities are discharged out of equipment through the slag outlet 23.
The sewage after pushing the impeller 18 to rotate passes through the connecting hole 33 on the baffle plate 2 and enters the oil removing bin 4, the lower edge of the oil scraping disc is immersed along with the continuous rising of the liquid level in the oil removing bin 4, as the temperature of the oil scraping disc becomes lower under the action of the coolant, the dissolved grease in the sewage can be adhered and solidified to the surface of the oil sticking disc 29, and the adhered and solidified grease on the surface of the oil sticking disc 29 is scraped off through the oil scraping plate 30 along with the rotation of the oil scraping disc, and finally the grease is discharged out of the device through the oil outlet 39.
Wherein in order to avoid overflow from the oil outlet 39 caused by overhigh sewage liquid level, the height of the water outlet pipe arranged on the side wall of the oil removal bin 4 cannot exceed the height of the oil outlet 39, and meanwhile, in order to ensure that the liquid level can be immersed into the oil sticky disc 29, the sewage which is not degreased in the process of rising the liquid level is prevented from flowing out, a buoyancy valve 32 is further arranged on the water outlet pipe, and the buoyancy valve 32 is opened only when the liquid level rises to a pressure which exceeds the opening pressure of the buoyancy valve 32, and at the moment, the sewage can be discharged through the water outlet pipe 31. In this process, since the density of the grease is smaller than that of the water, the grease always floats on the surface of the water, so that the liquid level of the sewage is raised above the buoyancy valve 32 after the sewage rises to push the buoyancy valve 32, and the grease is ensured not to flow out of the water outlet pipe before being filtered and deoiled by the oil pan 29.
In order to prevent the slag scraping plate 13 from pushing impurities on the filter plate 12 in the direction, a limit hole 37 is formed in one side of the sliding frame 7, a plug pin 36 is slidably arranged on the other side, a reset column 35 is arranged on the inner wall of the installation groove 6 opposite to the limit hole 37, a limit column 38 is arranged on the inner wall of the installation groove 6 opposite to the plug pin 36, the plug pin 36 is not fully inserted into the sliding frame 7 in the initial state, the plug pin 36 is pushed to be inserted into the sliding frame 7 when the slag scraping plate 13 moves to the higher side of the filter plate 12, and at the moment, the plug pin 36 is pushed to move upwards to the limit position by the filter plate 12, so that the plug pin 36 is positioned below the sliding block 14 after being inserted, the slag scraping plate 13 is prevented from being positioned at the upper limit position, the bottom of the slag scraping plate 13 is separated from the filter plate 12 after being reversely moved, and the impurities on the slag scraping plate 13 can not be reversely pushed to move, so that the blocking is caused; when the scraper 13 moves to the lower side of the filter plate 12, the reset post 35 is inserted into the limit hole 37 to push the latch 36 to move reversely, the latch 36 after the reverse movement is withdrawn from the lower side of the slider 14, when the scraper 13 moves to the higher side of the filter plate 12 again and the reset post 35 moves out from the lower side of the slider 14, the spring 15 stretches to push the slider 14 to move downwards, so that the bottom of the scraper 13 contacts the filter plate 12 again, and the filter plate 12 is cleaned.
In the embodiment, the oil pan 29 is made of stainless steel, and a sealing ring is arranged at the joint of the rotating shaft 27 and the communicating vessel 26 to prevent the coolant from leaking in the circulating process; in order to ensure that the impeller 18 pushed by water flow can drive the slag scraping plate 13 to normally move on the filter plate 12, the diameter of the driving belt wheel 19 is smaller than that of the driven belt wheel 20, so that the driving belt wheel 19 and the driven belt wheel 20 form a speed reducing mechanism, and the purpose of increasing the torque of the driving chain wheel 8 by reducing the rotating speed is achieved.
It is noted in this embodiment that the difference in height between the upper side and the lower side of the filter plate 12 does not exceed the distance the scraper 13 moves in the carriage 7. In order to prevent the latch 36 from falling off during the movement of the sliding frame 7, a limiting block 43 is arranged at the end of the latch 36, and a matched limiting groove 44 is arranged at a corresponding position on the limiting hole 37, so that the limiting block 43 can not influence the sliding of the sliding block 14 in the sliding frame 7 when the latch 36 is in an inserted or non-inserted state; in order to avoid the influence of the heat sink 47 on the cooling effect of the coolant in the cooling water tank 45 after the heat sink 47 is in contact with the cooling water tank 45, a heat insulating pad 50 is provided between the heat sink 47 around the semiconductor cooling fin 48 and the side wall of the cooling water tank 45.
