Description

Technical Field

[0001] This utility model relates to the field of equipment cleaning technology, and in particular to a filter device for a mechanized, zero-electricity, explosion-proof cleaning equipment for oil tanks. Background Technology

[0002] Containers for crude oil and its derivatives must be cleaned and disinfected before each use, whether for refilling with new oil or changing the type of crude oil being stored. The wastewater from this cleaning process contains a large amount of oil-water mixture, which, if discharged directly into the environment, will cause secondary pollution. Therefore, an oil-water mixture treatment system is needed to process the wastewater before discharging it to the outside or for other uses.

[0003] In existing oil-water separation and filtration equipment, some use filter screens or functional filter membranes for filtration. After the filter screens or membranes filter the oil residue, they are burned or otherwise treated harmlessly, and the filtered water is discharged to the outside or reused.

[0004] Filter screens or filter membranes have low filtration efficiency. In existing cases, there are also technical solutions that use sedimentation to filter and separate oil-water mixtures. However, natural sedimentation separation is slow, and the operation and intervention of the sedimentation and separation process are cumbersome and time-consuming, resulting in low efficiency and a large workload.

[0005] A more efficient filtration device that matches cleaning equipment is in high demand right now. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a filter device for a mechanized, zero-electricity, explosion-proof cleaning equipment for oil tanks, which can effectively solve the problems of insufficient functional richness and single functional structure of existing market products, and improve the working efficiency of product functions.

Filtered water outlets are respectively provided at the bottom of the first filter chamber and the second filter chamber. The observation windows are respectively located at the first filter port position of the first filter chamber and the second filter port position of the second filter chamber.

[0016] Figure 3 yes Figure 2 Another embodiment of the structure is shown in the schematic diagram. Detailed Implementation

[0017] like Figure 1-2 As shown in the figure, a specific embodiment of this utility model is a filter device for a mechanized zero-electricity explosion-proof cleaning equipment for oil tanks. The device includes a main body, which comprises a separation chamber 1. A light-transmitting observation window 2 is provided on the side wall of the separation chamber, and a sealed glass is provided on the observation window. An oil-water mixture inlet 3 is provided at the front of the separation chamber, and an inlet pump body 4 is connected to the oil-water mixture inlet. An inlet pipe 5 connects to the rear of the inlet and enters the separation chamber. A filter oil outlet 6 is provided at the lower front end of the separation chamber, and a drain pump body 7 is provided at the filter oil outlet. A filter buffer tank is provided below the outlet of the inlet pipe. 8. Filter holes 9 are provided at the bottom of the filter buffer tank. Two horizontal partitions are provided in the separation chamber, namely a first horizontal partition 10 and a second horizontal partition 11. A first filter port 12 is provided at the top of the first horizontal partition, and a second filter port 13 is provided on the second horizontal partition. The first filter port is a rectangular opening and is higher than the bottom of the filter buffer tank, while the second filter port is a rectangular opening and is lower than the first filter port. The first and second horizontal partitions divide the interior of the separation chamber into a first filter chamber 14, a second filter chamber 15, and a third filter chamber 16. The bottom part of the first and second filter chambers... The filter water outlet 17 is not provided. The observation windows are respectively located at the first filter port of the first filter chamber and the second filter port of the second filter chamber. During operation, the mixed sludge liquid after cleaning the oil tank is adsorbed into the inlet pipe by the inlet pump body and flows into the buffer filter tank through the inlet pipe port. It enters the first filter chamber through the filter holes at the bottom of the buffer filter tank. Large foreign objects or oil stains are filtered out and left in the buffer filter tank, forming a certain turbulence and buffering effect to prevent the new mixed liquid from having too strong an impact force and rushing to the bottom of the first filter chamber, so that the newly entered mixed liquid is flushed to the bottom of the buffer filter tank. The impact stops at the middle of the first filtration chamber after a short distance. Due to the heavier water and lighter oil, the oil floats and the water sinks. The floating oil surface rises to the first filter port and flows into the second filtration chamber. The sinking water is discharged to the outside for secondary use through the lower filter water outlet. The oil mixed with water flowing into the second filtration chamber through the first filter port undergoes secondary water sedimentation and oil-water separation. The continuously rising oil is separated and purified again before flowing into the third filtration chamber through the second filter port. The purified oil flowing into the third filtration chamber is discharged to other treatment equipment through the filter oil outlet. Both the inlet pump and the outlet pump are hydraulic centrifugal pumps.

[0018] The second embodiment of this utility model is as follows:

[0019] like Figure 3As shown, a turbulence fan blade is installed at the bottom of the buffer filter tank, and the turbulence fan blade is rotatably connected to the middle of the rear wall of the separation chamber. After the oil-water mixture filtered by the buffer filter tank flows into the first filter chamber, the flow velocity impacts the turbulence fan blade, causing it to rotate. The turbulence fan blade disperses the oil-water mixture and pushes it out laterally, further buffering and turbulent the flow, increasing the oil-water separation efficiency. Placing the turbulence fan blade in the middle of the separation chamber effectively prevents the oil-water mixture from entering the lower settling water section and being discharged through the filter port, thus improving the filtration effect.

[0020] The turbulence fan blades are rotatably connected to a connecting shaft 18 on the side wall. The connecting shaft is fixedly connected to the side wall of the separation chamber. An oil ball bearing 19 is fitted onto the connecting shaft. The turbulence fan blades include a central fan shaft 20 and fan blades 21 connected to the fan shaft. A shaft hole is provided in the center of the fan shaft, and this shaft hole fits onto the outer wall of the ball bearing. The ball bearing intervention ensures smoother rotation, better connection, and facilitates maintenance and replacement. The fan blades are three in number, evenly distributed along the circumference of the fan blade axis. Two blades are less effective at balancing the impact forces on both sides, while more than three blades are too dense and affect the impact speed. Three blades provide the optimal impact effect.

[0021] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the protection scope of this utility model.
