Description

Technical Field

[0001] This utility model relates to the field of chemical waste oil extraction technology, specifically a device for extracting chemical waste oil from chemical wastewater. Background Technology

[0002] With the rapid development of industries such as fine chemicals, petrochemicals, and pharmaceuticals, the oily wastewater discharged during production processes not only contains high concentrations of organic pollutants but also carries large amounts of floating oil, emulsified oil, and heavy hydrocarbons. If this waste oil is discharged directly into subsequent biological treatment systems without effective recovery, it will significantly inhibit microbial activity, increase the treatment load, and even cause secondary pollution; at the same time, the waste oil itself has considerable resource value. Therefore, efficient and low-energy oil-water separation and waste oil extraction before wastewater enters advanced treatment has become a key step in energy conservation, emission reduction, cost reduction, and efficiency improvement in the industry. Fixed structures prevent the oil absorption interface from adjusting in real time according to liquid level, oil layer thickness, or fluctuations in incoming water, resulting in "dry suction" or "over-suction" phenomena, reducing the recovery rate. Utility Model Content

[0003] The purpose of this invention is to provide a device for extracting chemical waste oil from chemical wastewater, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for extracting chemical waste oil from chemical wastewater, comprising a wastewater tank, an inlet valve and a drain valve respectively provided on both sides of the wastewater tank, a height adjustment assembly provided in the inner cavity of the wastewater tank, the height adjustment assembly including a rotating shaft, the rotating shaft being movably sleeved on the upper part of the inner cavity of the wastewater tank, a support block being fixedly sleeved on the outer side of the rotating shaft, a telescopic rod being connected to the outer side of the support block, an oil suction plate being connected to one end of the telescopic rod, an external thread being provided on one side of the rotating shaft, a threaded cylinder being threaded to the outer side of the external thread, a moving block being connected to one end of the threaded cylinder, a connecting rod being hinged to the outer side of the moving block, and one side of the connecting rod being hinged to the inner side of the oil suction plate.

[0005] As a further improvement of this utility model, a first motor is installed on the side of the sewage tank, and the output end of the first motor is connected to a rotating shaft.

[0006] As a further improvement of this utility model, the outer side of the support block is provided with four telescopic rods and oil-absorbing plates, which are distributed along the four sides of the support block.

[0007] As a further improvement of this utility model, a base is installed at the bottom of the sewage tank, a second motor is installed at the bottom of the base, the output end of the second motor is connected to a stirring blade located in the inner cavity of the sewage tank, and a heating rod is installed at the bottom of the inner cavity of the sewage tank.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This device for extracting chemical waste oil from chemical wastewater connects the outer side of the rotating shaft to a threaded cylinder via an external thread. Rotating the threaded cylinder causes the moving block to move on the outer side of the rotating shaft. Since the oil suction plate is connected to the support block and the moving block via a telescopic rod and a connecting rod, the distance between the oil suction plate and the rotating shaft can be adjusted. This allows for easy adjustment of the position of the oil suction plate according to the height of the wastewater in the wastewater tank, making this device suitable for use with wastewater of different amounts and depths in the wastewater tank.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides a device for extracting chemical waste oil from chemical wastewater, including a wastewater tank 1. The wastewater tank 1 is provided with an inlet valve 2 and a drain valve 3 on both sides. The inner cavity of the wastewater tank 1 is provided with a height adjustment component 4, which includes a rotating shaft 42. The rotating shaft 42 is movably sleeved on the upper part of the inner cavity of the wastewater tank 1. A support block 43 is fixedly sleeved on the outer side of the rotating shaft 42. A telescopic rod 44 is connected to the outer side of the support block 43. One end of the telescopic rod 44 is connected to an oil suction plate 45. One side of the rotating shaft 42 is provided with an external thread 46. A threaded cylinder 47 is threaded to the outer side of the external thread 46. One end of the threaded cylinder 47 is connected to a moving block 48. A connecting rod 49 is hinged to the outer side of the moving block 48. One side of the connecting rod 49 is hinged to the inner side of the oil suction plate 45. The outer side of the rotating shaft 42 is connected to the threaded cylinder 47 via the external thread 46. By rotating the threaded cylinder 47, the moving block 48 is moved to the outside of the rotating shaft 42. Since the oil suction plate 45 is connected to the support block 43 and the moving block 48 via the telescopic rod 44 and the connecting rod 49 respectively, the distance between the oil suction plate 45 and the rotating shaft 42 can be adjusted. This makes it easy to adjust the position of the oil suction plate 45 according to the height of the sewage in the sewage tank 1, so that this device is suitable for use in sewage of different amounts and depths in the sewage tank 1.

[0021] A first motor 41 is installed on the side of the sewage tank 1, and the output end of the first motor 41 is connected to a rotating shaft 42. The first motor 41 is connected to the rotating shaft 42, and the first motor 41 drives the rotating shaft 42 and the oil suction plate 45 to rotate, thereby rotating the oil suction plate 45 to pick up the oil for cleaning.

[0022] The support block 43 is equipped with four telescopic rods 44 and oil suction plates 45 on its outer side, which are distributed along the four sides of the support block 43. Four sets of oil suction plates 45 are provided on the outer side of the rotating shaft 42, allowing one oil suction plate 45 to be replaced with another when it is full of oil, enabling continuous oil extraction and improving work efficiency.

[0023] A base 5 is installed at the bottom of the wastewater tank 1, and a second motor 6 is installed at the bottom of the base 5. The output end of the second motor 6 is connected to a stirring blade 7 located inside the wastewater tank 1. A heating rod 8 is installed at the bottom of the inner cavity of the wastewater tank 1. By activating the heating rod 8, the wastewater in the wastewater tank 1 is heated, preventing the oil from solidifying. The second motor 6 drives the stirring blade 7 to rotate, ensuring that the wastewater in the wastewater tank 1 is heated evenly and accelerating the extraction of waste oil.

[0024] There are four sets of heating rods 8, which are distributed at the four corners of the bottom of the sewage tank 1. The heating efficiency is improved by setting multiple sets of heating rods 8.

[0025] Working principle: When using this device, the wastewater requiring oil extraction is poured into the wastewater tank 1 through the inlet valve 2. The second motor 6 and the heating rod 8 are started respectively. The heating rod 8 heats the wastewater, and the second motor 6 drives the stirring blade 7 to rotate, so that the wastewater in the wastewater tank 1 can be heated quickly. According to the amount of wastewater in the wastewater tank 1, the rotating screw cylinder 47 drives the moving block 48 to move, thereby driving the oil suction plate 45 to move along the telescopic rod 44, so that the oil suction plate 45 comes into contact with the wastewater. The oil suction plate 45 absorbs the oil in the wastewater. When it is full, the first motor 41 drives the rotating shaft 42 to rotate the unused oil suction plate 45 to come into contact with the wastewater. The oil-covered oil suction plate 45 is cleaned off with external tools.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
