DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0021] refer to Figures 1 to 4

[0022] A dewaxing wastewater treatment tank comprises a tank body 100, in which a grease trap 110 is arranged, and the front and rear parts above the grease trap are rotatably connected with transverse rotating shafts 120 respectively, wherein one transverse rotating shaft is driven to rotate by a driving mechanism, sprockets 121 are fixed to both sides of the transverse rotating shaft, a driving chain 122 is wound between the front and rear sprockets on the same side, a transverse scraper 130 is fixed between the two driving chains, and a receiving groove 150 for receiving foam scum is arranged on the rear side of the grease trap, so that the scum can be scraped into the receiving groove by the transverse scraper for collection and removal.

[0023] In this embodiment, in order to drive the transverse rotating shaft to rotate, the driving mechanism includes a mounting frame 140 fixed to the rear side of the pool body, a reduction motor 141 is fixed to the mounting frame, a driving gear 142 is fixed to the output end of the reduction motor, a driven gear 143 is fixed to one end of the transverse rotating shaft located at the rear side, and a transmission chain 144 is wound between the driving gear and the driven gear. Thus, the reduction motor drives the driving gear to drive the driven gear to rotate, thereby realizing the rotation of the transverse rotating shaft.

[0024] In this embodiment, in order to better collect scum, both side walls of the receiving groove are inclined surfaces 151, and a waste slag discharge pipe 152 is connected to the bottom of the receiving groove. The waste slag discharge pipe is inclined downward, and a waste slag collection container 153 is arranged at the lower side of the output port of the waste slag discharge pipe. The waste slag is collected by the waste slag collection container for centralized treatment.

[0025] In this embodiment, in order to better discharge the scum, a guide slope 111 is connected to the upper part of the rear side wall of the grease trap to assist in discharging the foam scum, and a transverse scraper is used to keep the guide slope in an inclined state during the upward rotation process, so that the scum and foam fall into the receiving groove.

[0026] In this embodiment, the grease trap is divided into a first filter tank 113 and a second filter tank 114 by a vertical partition 112 arranged longitudinally, and a slot 115 is provided between the lower end of the vertical partition and the bottom plate of the isolation tank to connect the first filter tank and the second filter tank, and a baffle 116 connected to the bottom plate of the isolation tank and close to the partition is provided in the second filter tank. The foam film and scum float on the upper surface of the wastewater in the filter tank, and the wastewater flows into the second filter tank through the slot.

[0027] In this embodiment, a dewaxing wastewater inlet pipe 117 is provided on one side wall of the upper part of the first filter tank, and a one-way valve is provided on the dewaxing wastewater inlet pipe to avoid siphoning.

[0028] In this embodiment, in order to better scrape off the scum on the upper surface of the first filter tank and the second filter tank, a notch 131 is provided in the middle of the scraper to avoid the vertical partition.

[0029] In this embodiment, in order to realize the connection between the transverse scraper and the drive chain, an angle plate 132 is installed on one of the links of the two drive chains, and a connecting plate 133 is transversely fixed between the two angle plates. The transverse scraper is fixed on the connecting plate, so that the rotation of the two drive chains drives the transverse scraper to rotate, and then is used to scrape the scum on the surface of the oil separator. When the transverse scraper rotates to the bottom of the transverse shaft located at the rear side, the distance from the cantilever end of the transverse scraper to the center of the transverse shaft is slightly greater than the distance from the guide slope to the center of the transverse shaft, and because the transverse scraper is a plastic plate or a rubber plate, the transverse scraper can be slightly deformed when it contacts the guide slope, so as to better scrape the scum and foam into the receiving groove.

[0030] In this embodiment, a control cabinet is provided on one side of the pool body, and a timer is provided in the control cabinet to intermittently start the reduction motor, scrape the scum by the transverse scraper, and stop the reduction motor after rotating for a certain period of time. Alternatively, the reduction motor can be started and stopped manually by a worker.

[0031] In this embodiment, a reaction pool 160 is further provided on one side of the isolation pool in the pool body. A second transverse scraper 170 for scraping off the scum on the upper surface of the reaction pool is provided on the upper side of the reaction pool, and a second receiving groove 180 is provided on the rear side of the reaction pool. The second receiving groove is connected to the waste collection container via a second waste discharge pipe 181 so as to receive the scum, foam, etc. scraped off by the second transverse scraper. A second transverse rotating shaft 190 is provided at the front and rear parts of the upper side of the reaction pool, and one end of the transverse rotating shaft at the rear side is connected to the driven gear, so that the transverse rotating shaft and the second transverse rotating shaft are synchronously driven by the driving mechanism to reduce costs. Second sprockets are fixed on both sides of the two second transverse rotating shafts, and a second chain is wound around the second sprocket on the same side, and the two sides of the second transverse scraper are respectively connected to one of the links of the two second chains.

[0032] If the words "first", "second" and the like are used in the above-mentioned utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above-mentioned words have no special meaning.

[0033] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0034] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0035] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated forming process.

[0036] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
