Technical Field

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

[0002] The oil removal device is used to remove oil from oily wastewater. The oil removal device consists of a support frame, a motor, a magnet wheel, a steel belt, a mounting frame, a guide wheel, a collection box, an oil scraper, and an oil pipe. When using the oil removal device, the support frame is fixed to the wastewater tank with screws, and then the steel belt is installed on the magnet wheel. The steel belt is located in the wastewater tank. The motor is started to rotate the magnet wheel, so that the guide wheel and the magnet wheel on the mounting frame absorb the steel belt and cooperate to make the steel belt rotate, so that the steel belt passes through the water surface and adheres to the oil. As the steel belt rotates, it is scraped into the collection box by the oil scraper in the collection box, and then flows into the external receiving barrel through the oil pipe, thereby removing oil from the oily wastewater.

[0003] The inventor discovered in his daily work that when the oil removal device is in use, since the lower part of the steel belt is placed in the wastewater tank, oil will adhere to both sides of the steel belt when it passes through the water surface, and oil will adhere to the space between the steel belt and the magnet wheel, which may affect the rotation of the steel belt.

[0006] The effect achieved by the above components is: by setting up a scraping assembly, when it is necessary to scrape one side of the steel belt and the magnet wheel, the steel belt rotates, and the scraping block on the inner wall of the groove block contacts the steel belt, thereby scraping off the oil attached to the steel belt, thereby preventing it from entering between the magnet wheel and the steel belt, and thus achieving the effect of avoiding affecting the rotation of the steel belt as much as possible.

[0007] Preferably, one end of the scraper block is fixedly connected to a first spring, and the other end of the first spring is fixed to the grooved block.

[0008] The effect achieved by the above components is that the first spring is provided to squeeze the scraper block so as to fully contact the steel strip.

[0009] Preferably, an auxiliary hole is opened on one side of the scraping block, and a mounting frame is fixedly connected to the front side of the support frame.

[0010] The effect achieved by the above components is that the scraping block scrapes off the oil by providing the auxiliary hole, and the oil falls from the auxiliary hole.

[0011] Preferably, the slotted block is inserted into the installation frame, and a latch is inserted into the upper end of the installation frame.

[0012] The effects achieved by the above components are: dragging the latch to separate it from the grooved block, and then dragging the grooved block to separate it from the mounting frame, so that the scraping block can be cleaned.

[0013] Preferably, the latch is inserted into the slotted block, and a second spring is fixedly connected between the latch and the mounting frame.

[0014] The effect achieved by the above components is: by providing the second spring, the second spring pulls the latch and performs auxiliary limiting on the latch.

[0016] The effect achieved by the above components is: when the magnet wheel needs to be installed on the mounting rod, the magnet wheel is dragged to be locked into the mounting rod, and the pushing mechanism is used to move the push block, thereby pushing the insertion rod to be inserted into the magnet wheel, thereby fixing the magnet wheel.

[0017] Preferably, a screw rod is threadedly inserted into one end of the mounting rod, and the screw rod is rotatably connected to the push block.

[0018] The effect achieved by the above components is: twisting the screw rod causes the push block to move.

[0019] In summary, the beneficial effects of the present invention are as follows:

[0020] In the utility model, a scraping assembly is provided. When it is necessary to scrape one side of the steel belt and the magnet wheel, the steel belt rotates, and the scraping block on the inner wall of the groove block contacts the steel belt, thereby scraping off the oil attached to the steel belt, thereby preventing the oil from entering between the magnet wheel and the steel belt, thereby avoiding affecting the rotation of the steel belt as much as possible. The problem that the lower part of the steel belt is placed in the wastewater tank, so that when the steel belt passes through the water surface, oil will be attached to both sides of the steel belt, and oil will be attached between the steel belt and the magnet wheel, thereby possibly affecting the rotation of the steel belt is solved.

[0029] Reference Figure 3 and Figure 4 As shown, in this embodiment: the scraping assembly 2 includes a grooved block 21 arranged on the front side of the support frame 1, and the inner wall of the grooved block 21 is slidably connected with a scraping block 22. By setting the scraping assembly 2, when it is necessary to remove one side of the steel belt 12 and the magnet wheel 6, the steel belt 12 rotates, and the scraping block 22 on the inner wall of the grooved block 21 contacts the steel belt 12, thereby scraping off the oil attached to the steel belt 12, thereby avoiding it from entering between the magnet wheel 6 and the steel belt 12, and thus achieving the effect of avoiding affecting the rotation of the steel belt 12 as much as possible. One end of the scraping block 22 is fixedly connected to a first spring 23, and the other end of the first spring 23 is fixed to the grooved block 21. By setting the first spring 23, the scraping block 22 is squeezed to contact the steel belt 12. The belt 12 is in full contact, an auxiliary hole 24 is opened on one side of the scraper block 22, and a mounting frame 25 is fixedly connected to the front of the support frame 1. By setting the auxiliary hole 24, the scraper block 22 scrapes off the oil, thereby falling from the auxiliary hole 24, and the grooved block 21 is inserted into the mounting frame 25. A latch 26 is inserted at the upper end of the mounting frame 25. The latch 26 is dragged to separate it from the grooved block 21, and then the grooved block 21 is dragged to separate it from the mounting frame 25, so that the scraper block 22 can be cleaned.

A screw rod 34 is threadedly inserted at one end of the mounting rod 5, and the screw rod 34 and the push block 33 are rotatably connected. The screw rod 34 is twisted to move the push block 33.

[0031] Working principle:

[0032] When using the oil removal device, the support frame 1 is fixed to the wastewater tank by screws, and then the steel belt 12 is installed on the magnet wheel 6. The steel belt 12 is located in the wastewater tank, and the motor 4 is started to make the magnet wheel 6 rotate, so that the guide wheel 8 on the mounting frame 7 and the magnet wheel 6 adsorb the steel belt 12 and cooperate to make the steel belt 12 rotate, so that the steel belt 12 passes through the oil attached to the water surface. As the steel belt 12 rotates, it is scraped into the collection box 9 by the scraping block 11 in the collection box 9, and then flows into the external receiving barrel through the oil pipe 10, thereby degreasing the oily wastewater. When it is necessary to remove one side of the steel belt 12 and the magnet wheel 6 for scraping, the steel belt 12 rotates, and the scraping block 22 on the inner wall of the groove block 21 contacts the steel belt 12, thereby scraping off the oil attached to the steel belt 12, thereby preventing it from entering between the magnet wheel 6 and the steel belt 12, and then In order to avoid affecting the rotation of the steel belt 12 as much as possible, the first spring 23 is provided to squeeze the scraper block 22 so that it is in full contact with the steel belt 12. By providing the auxiliary hole 24, the scraper block 22 scrapes off the oil, so that it falls from the auxiliary hole 24, dragging the latch 26 to separate it from the grooved block 21, and then dragging the grooved block 21 to separate it from the mounting frame 25, so that the scraper block 22 can be cleaned. By providing the second spring 27, the second spring 27 pulls the latch 26 to assist in limiting the latch 26. When the magnet wheel 6 needs to be installed on the mounting rod 5, the magnet wheel 6 is dragged so that it is stuck in the mounting rod 5, and the screw rod 34 is turned to move the push block 33, so that the push block 33 moves, thereby pushing the insertion rod 32 to be inserted into the magnet wheel 6, and then fixing the magnet wheel 6.
