Description

A waste oil collection device

technical field

The utility model relates to a waste oil collecting device for the lubrication of an emulsion process in a metallurgical cold-rolled ordinary carbon steel plate.

Background technique

The existing cold-rolled plain carbon steel units generally use emulsion (aqueous solution containing 3-5% emulsifier) for rolling, and its participation in the rolling process has many advantages: one is to reduce the total rolling force; To the role of cooling roll; the third is to reduce the wear of the roll, and so on. However, in the rolling process, the emulsion has been in the process of recycling. When the emulsion is sprayed on the surface of the roll, it takes away the heat of the roll, and also takes away the wear particles of the roll, the tiny particles on the surface of the strip, Lubricating oil for roll bearings (belonging to oil leakage) and other mechanical oil leakage, etc. When these particles and oil spills return to the pool together with the emulsion, the particles can be filtered out by mechanical filtration. At this time, the waste oil is lighter than water in density, so it floats on the water surface, and the longer it floats The waste oil will accumulate more and more, and it will stink more easily. If it is not treated, it will seriously affect the performance indicators of the emulsion, and finally all the emulsion can only be replaced. If the method of manual treatment is adopted: the one, the operating environment is relatively poor, the oil pollution is much, and the safety to workers is relatively poor; the second is that the treatment effect is not very satisfactory, the waste oil treatment is not clean, and the production cost is increased.

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages, thereby providing a waste oil collecting device, which can clean up the waste oil floating in the emulsion in time, greatly improves the waste oil treatment capacity, low production cost and good use effect.

According to the technical solution provided by the utility model, a waste oil collection device includes a small centrifugal pump, a floating ball device, a waste oil collection box, an oil inlet pipe and an oil outlet pipe. The suction port of the small centrifugal pump is installed on a set of floating ball device, and the floating ball device is installed in the emulsion tank, and the outlet end of the small centrifugal pump enters the waste oil collection tank, and the suction device of the floating ball device and the One end of the oil inlet pipe is connected between the inlets of the small centrifugal pump, the other end of the oil inlet pipe is connected with the oil outlet pipe, and the oil outlet pipe is connected between the outlet of the small centrifugal pump and the waste oil collection box.

The floating ball device is composed of a floating ball, a suction device, an adjusting nut and an adjusting bolt. The middle of the floating ball is a hollow structure, 4 floating balls are connected by bending thin plates, and the suction device is fixed by adjusting nuts and adjusting bolts in the middle, and the suction device is like a funnel. The oil inlet pipe must be a hose.

Compared with the prior art, the utility model has the following advantages:

The utility model has a simple, compact and reasonable structure; it can clean up the waste oil floating in the emulsion in time, and the waste oil treatment capacity is greatly improved. Usually, the waste oil collection device only needs to be turned on for 1 to 2 hours a day to remove the waste oil produced by the rolling mill. The waste oil is sucked away, the operation is simple, the production cost is extremely low, and the use effect is good.

Detailed ways

Below the utility model will be further described in conjunction with the embodiment in the accompanying drawing:

As shown in Figure 1 and Figure 2: including small centrifugal pump 1, floating ball device 2, waste oil collection box 3, oil inlet pipe 4, oil outlet pipe 5, floating ball 6, suction device 7, adjusting nut 8 and adjusting bolt 9 wait.

The power source of the utility model is a small centrifugal pump 1, the suction port of the small centrifugal pump 1 is installed on a set of floating ball device 2, and the floating ball device 2 is installed in the emulsion pool, because the liquid level of the emulsion is not fixed , will change along with the change of liquid level height, and float device 2 has solved this problem just in time. The outlet end of the small centrifugal pump 1 enters the waste oil collecting tank 3, and the waste oil entering the tank can be used for the next step of environmental protection treatment. An oil outlet pipe 5 is connected between the outlet of the small centrifugal pump 1 and the waste oil collection box 3; one end of the oil inlet pipe 4 is connected with the float device 2 .

The floating ball device 2 is composed of a floating ball 6 , a suction device 7 , an adjusting nut 8 and an adjusting bolt 9 . The middle of the floating ball 6 is a hollow structure, and it is sealed with the outside world. It mainly plays the role of a float. The four floating balls 6 are connected by bending thin plates, and the suction device 7 is fixed by the adjusting nut 8 and the adjusting bolt 9 in the middle. The suction device 7 is like a funnel;

The use process of the utility model: the middle of the floating ball 6 is a hollow structure, and it is sealed with the outside world, and mainly plays the role of a float. The four floating balls are connected by bending thin plates, and the suction device 7 is fixed by the adjusting nut 8 and the adjusting bolt 9 in the middle. The suction device 7 is like a funnel; when the ball float device 2 was put into the pool like this, the total gravity of the ball float device 2 was less than the buoyancy produced by its total volume, so the ball float device 2 would float on the water surface, and in the suction device Connect the oil inlet pipe 4 between 7 and the inlet of the power source 1. The oil inlet pipe 4 must be a hose, so that it can not affect each other with the change of the liquid level. Connect the outlet between the outlet of the power source 1 and the waste oil collection box 3. Oil pipe 5; at this time, it is necessary to adjust the distance S of the suction device 7 under the liquid surface, which can be adjusted to an appropriate distance by adjusting the nut 8. The distance S should not be too large, if it is too large, too much emulsion will be sucked; it should not be too small, if it is too small, the ability to suck waste oil will be reduced, or even no oil can be sucked. The whole device has just been installed like this, as long as the centrifugal pump is started, it can start working.
