Description

TECHNICAL FIELD

[0001] The utility model relates to the field of factory stirring equipment especially a kind of waste dry oil recovery dilution stirring filter device of rolling mill. BACKGROUND

[0002] In the production process of rolling mill, different kinds of lubricating grease are used in each link, part of which can be recycled, for example, when rolling mill produces various sizes of steel, the cold bed apron lattice grid is prone to steel falling, so oil is applied on the surface of apron lattice grid for lubrication to reduce the probability of steel falling, and the required oil product is high-temperature-resistant dry oil grease. During the assembly process of finishing mill of rolling mill, a lot of excess lubricating grease is squeezed on the outer side of bearing, which cannot play its own lubricating role, but after the rolling mill is put into operation, the lubricating grease is washed into the return water channel by cooling water, polluting the turbid circulating water. The bearing special lubricating grease is used for bearing of rolling mill, and the product uses composite lithium-calcium soap thickened high-viscosity mineral base oil, which has good high-temperature resistance. These excess waste dry oils can be recycled. The waste dry oils are collected and used in places where the oil used in equipment does not require high cleanliness, such as the surface of cold bed apron lattice grid. Because the viscosity of these waste dry oils is high and they are mixed with metal impurities, they cannot be directly used and need to be mixed with diluent oil for stirring and dilution. The recycled waste dry oil and recycled diluent oil are mixed in an iron barrel by manual operation, stirred manually, and then taken out manually and put into a small oil barrel, which is laborious, time-consuming and pollutes the surrounding environment. At the same time, the large-particle impurities in waste dry oil will also affect the final yield of steel products during smearing. In order to reduce the labor intensity and improve the efficiency, an electric dilution stirrer is needed to replace manual operation. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a waste dry oil recovery dilution stirring filter device for rolling mill, which can efficiently dilute, stir and filter the collected waste dry oil by adding diluent oil, so that the stirred and diluted oil can be used in places where the oil used in equipment does not require high cleanliness, which can not only recycle waste and reduce cost, but also reduce labor intensity and improve efficiency.

[0013] Figure 2 This is a top view of the measuring ruler of this utility model;

[0014] The components are: 1. base, 2. support column, 3. geared motor, 4. mixing oil tank, 5. lever connection part, 6. lever extension part, 7. oil filling port, 8. groove, 9. support seat, and 10. lever mixing part. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to embodiments:

[0016] like Figure 1 The diagram shows a structural schematic of a waste oil recovery, dilution, stirring, and filtration device for steel rolling mills. It includes a base 1 on the ground, with a vertically upward-pointing support column 2 fixed on the base 1. The support column 2 is a quadrangular prism, with an outward-extending geared motor mounting seat on its top side. The mounting seat has a flat surface, and a geared motor 3 is mounted on it using bolts or welding. The geared motor 3 is suspended in mid-air, with its output shaft pointing vertically downwards. In this embodiment, the geared motor 3 can be a 0.75KW motor integrated into a planetary gear transmission. A lever mounting plate is fixedly fitted onto the output shaft, and at least four levers are fixedly mounted on the bottom surface of the lever mounting plate. The lever body is a rectangular steel sheet, which is then made into a three-section lever. The rectangular steel sheet is vertically bent into an L-shape, with the shorter part of the L-shape being the protruding part 6 of the lever. Figure 2 As shown, the protruding part 6 of the lever is horizontally connected and fixed to the bottom surface of the lever mounting plate. In this embodiment, there are 4 levers, and the lengths of the protruding parts of the four levers are different. This allows each lever to have a different stirring radius. When the levers rotate in the oil drum, the circles drawn by each lever are different and not concentric, resulting in a better stirring effect. The top of the longer L-shaped part is the lever connecting part 5, which is connected to the protruding part and hangs vertically downward. After heating the part of the longer L-shaped part from the middle downward, it is twisted 90 degrees axially and then cooled and shaped. After shaping, the hanging part of the lever is similar to a twisted rope. The rectangular steel sheet is no longer a thin end facing the stirring direction, but a steel sheet twisted 90 degrees with the wide end facing the stirring direction. The wide end face twisted and connected on the lever connecting part 5 is the lever stirring part 10. On the one hand, the contact area between the wide end and the waste dried oil is increased, resulting in a better stirring effect. On the other hand, the lever is made of a single rectangular steel sheet, which is not only strong and not easy to break, but the arc brought by the twist can also play a transition effect, making the stirring smoother.

[0017] The four stirrers hanging on the stirrer mounting disc extend into the stirring oil barrel 4. The stirring oil barrel body is a cylindrical oil barrel, and only a semicircular conical oil filler 7 extending outward is arranged at the edge of the open top to make the opening at the top of the oil barrel larger. Workers can use a shovel to collect waste dry oil and transport the waste oil to the oil barrel at the extended oil filler 7. The oil recovery barrel 4 is provided with an oil outlet at the bottom of the side wall. The side wall of the stirring oil barrel 4 has a certain thickness, and the oil outlet is a circular opening. The oil outlet is provided with a side opening cover. An oil taking pipe with a size matching the oil outlet is additionally provided. When taking oil, the side opening cover is opened, and the oil taking pipe is connected to the oil outlet to realize oil taking. Of course, a shovel can also be used to take oil from the opening of the oil barrel. A filter screen is arranged at the oil outlet of the oil taking pipe to filter out large particles in the oil. The oil outlet of the oil taking pipe is introduced into a small barrel, and the extracted oil is first introduced into the small barrel, and then the small barrel is carried to the subsequent smearing place.

[0018] In order to ensure that the air pressure is sufficient to press the oil out, and at the same time to leave space for the small barrel, the stirring oil barrel 4 is provided with a support seat 9 inserted with the support column 2. The support seat 9 supports the stirring oil barrel 4. The height of the support seat 9 can be adjusted to adjust the height of the stirring oil barrel 4, the depth of the stirrer, and the stirring degree to adapt to stirring oil barrels of different sizes. Specifically, a rectangular groove 8 is formed on the surface close to the stirring oil barrel 4 of the support column 2. The support seat 9 is a plurality of rectangular pads with the same size. The width of the rectangular pad is matched with the width of the groove 8. The rectangular pad can be inserted into the groove 8 of the support column 2. The number of pads can be adjusted as needed.

[0019] In order to further improve the stability of multiple pads and facilitate simultaneous movement, a corresponding long strip-shaped through hole is arranged on the side wall of the groove of the support column. In order to cooperate, a circular through hole is arranged on one end of the rectangular pad inserted into the groove 8. The position of the circular through hole and the long strip-shaped through hole corresponds. When the required number of pads are inserted into the groove 8, a screw rod is used to pass through the circular through hole on the pad and the long strip-shaped through hole on both sides of the groove at the same time. The screw rod is provided with nuts on both sides, which are tightened at the same time. The pad and the support column 2 are fixed, which greatly improves the stability and can even be dragged at the same time.

[0020] When the new type is used, the staff first collects waste dry oil at various places in the steel rolling mill, introduces the waste dry oil into the stirring oil barrel, and then pours dilute oil into the stirring oil barrel according to the amount of waste dry oil, which can be scrap lubricating oil. The reduction motor is started, and the stirrers start to rotate and stir the waste dry oil and the dilute oil. The stirred oil is introduced into a small barrel for subsequent use in places where high cleanliness of lubricating grease is not required, such as smearing the surface of the skirt plate grid of the cooling bed.

[0021] The above-described embodiments are merely preferred embodiments of the present application, and are not intended to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements to the technical solutions of the present application made by those of ordinary skill in the art shall fall within the protection scope of the present application as defined by the claims.
