Preferably, a side door is provided on one side of the garbage collection box to facilitate removal of internal garbage at the bottom.

Preferably, the guide soft plate is made of rubber, which can deform when the arc-shaped scraper comes into contact to avoid interference.

Compared with the prior art, the beneficial effects of the present invention are as follows:

1) By installing a buffer plate on one side of the water inlet pipe in the oil removal chamber, it can not only buffer the water flow, but also act as a guide, so that the lighter oil can quickly float on the water surface, which facilitates subsequent oil removal and cleaning work. conduct;

2) By setting up two sets of oil suction mechanisms, and cooperating with the lifting mechanism, the oil suction mechanisms can be raised or lowered at the transfer ports at both ends of the limit frame II. Even if one group of oil suction mechanisms needs to be desorbed, the normal operation of the other group of oil suction mechanisms can be ensured. operation to achieve the effect of cyclic oil removal and greatly improve the oil removal efficiency;

3) The built-in motor driving wheel in the oil suction mechanism reciprocates in the limit frame II. The hub motor drives the oil suction roller to rotate. The electric telescopic rod I controls the height of the connecting frame through the telescopic frame to adjust the height of the oil suction roller to complete various liquid levels. At the same time, the cleaning plates set on the movable frames at both ends of the fixed shaft can clean the side walls of the oil removal chamber during the reciprocating motion, and guide the oil dirt near the side walls to the side of the oil suction roller through the guide soft plate. , complete the oil suction work. When changing the movement direction of the oil suction roller, the motor II output end gear meshing drive can also be used to drive the movable frame to rotate, thereby controlling the direction of the cleaning plate, ensuring the cleaning and guiding of the side oil stains, greatly improving the oil absorption efficiency and range, which can prevent oil stains from being adsorbed on the side wall of the oil removal chamber for a long time and causing pollution;

4) In the oil scraping mechanism, by setting up two sets of arc-shaped scrapers that are in contact with each other and chamfering the concave and convex areas respectively, it can play a guiding role. At the same time, when the arc-shaped scrapers scrape the oil suction roller, The bumps can penetrate deep into the oil suction roller for squeezing, so that the oil suction roller can be scraped more thoroughly. The anti-overflow baffle can prevent oil stains from overflowing the arc-shaped scraper and being absorbed by the oil suction roller again. After the oil stains are scraped out, they will be collected and flowed out through the oil guide groove. Gravity finally drips into the oil receiving box. Due to the low overall temperature of the oil receiving box, the oil solidifies after dripping into the oil receiving box, and is extended by the electric telescopic rod IX, driving the oil scraper to move to the movable door. When it is turned sideways, the tilted top plate pushes up the movable door, and then the solidified oil dirt blocks fall into the oil dirt collection box below and are collected and stored uniformly. This completes the scraping and cleaning of the oil suction roller, and simultaneously completes the collection of oil dirt, which not only affects the oil suction roller. Scraping oil is more thorough, and the preservation of oil contamination can also effectively prevent oil from splashing or adsorbing on the side walls of the equipment to form an oil layer;

5) When the oil suction roller moves to close to one end of the fixed scraper, the electric telescopic rod IV drives the movable beam to move so that the brush fits one side of the oil suction roller. Then the electric telescopic rod V reciprocates and contracts, driving the brush to reciprocate along the movable beam. At the same time, the water pump II in the clean water tank flows into the shunt pipe, and sprays out through the nozzle on the fixed water tank, and cooperates with the brush to complete the scrubbing operation of the oil suction roller, and through the rotation of the oil suction roller and the fixed scraper, the clean water is Extrusion, in this way, the oil suction roller can be deeply cleaned, so that the oil suction roller always maintains a strong oil absorption capacity, and avoids the accumulation of oil in deep layers, which affects the oil absorption effect;

6) By setting up a filtration method in which the filter box and the filter plate cooperate, it is different from the existing filter plates placed horizontally or vertically or at an angle. Three-dimensional filtration is achieved through the filter box and the filter plate, which can achieve solid-liquid separation of large flow sewage. It can effectively prevent solid waste from blocking the filter holes under the impact of water flow. The three-dimensional filtration method greatly improves the filtration efficiency and effectively ensures the efficiency of solid-liquid separation;

7) When the filter box cooperates with the filter plate for solid-liquid separation, the electric telescopic rod VIII drives the top plate I to move, and cooperates with the thimble I to clean the filter holes on the side wall of the filter box to avoid clogging of the filter holes and complete one side of the filter box. After the filter holes are cleaned, the top plate I is reset. At this time, the motor VIII is driven by gear meshing to drive the movable disk to rotate, which drives the filter box to rotate as a whole, so that the uncleaned side faces the top plate I, and the cleaning of the filter holes on the side of the filter box is completed again. Working, through the cooperation of the top plate Ⅰ and the ejector pin Ⅰ, the filter holes of the filter box can be quickly cleaned, further avoiding the clogging of the filter holes and improving the filtration efficiency;

8) Use the electric telescopic rod VI to drive the fixing frame II to move along the chute on the inside of the filter box, driving the filter plate to move so that the filter plate is flush with the top of the filter box. Then, through the extension of the electric telescopic rod VII, the top plate II is raised. As a result, the ejector pin II is inserted into the filter hole on the filter plate to complete the cleaning of the filter hole on the filter plate, and the head of the ejector pin II will be flush with the surface of the filter plate to prevent garbage from clogging the filter hole again during the scraping process, and then cooperate with scraping. The mechanism completes the removal of solid waste. The setting of the top plate II and the thimble pin II can clean the filter holes on the filter plate. At the same time, during the process of scraping the solid waste, the thimble pin II can always be inside the filter hole and flush with the filter plate. , to prevent garbage from being squeezed into the filter holes during the process of scraping garbage, ensuring the scraping effect while effectively avoiding clogging of the filter plate and ensuring solid-liquid separation efficiency.
