Description

Technical Field

[0001] The utility model belongs to the technical field of filtering devices, and in particular relates to a filtering device for cold rolling oil processing. Background Art

[0002] Cold rolling oil is a special lubricating oil used to prevent oxidation and corrosion on the surface of steel plates during the cold rolling process.

[0003] After use, cold rolling oil is often mixed with impurities such as iron filings, causing the intact rolling oil to be artificially discarded in the process. The existing filtering devices often have low processing accuracy for iron filings and take a long time. Therefore, due to the lack of effective processing methods, some of the used cold rolling oil can only be used as sintering raw materials or directly landfilled, which is likely to cause environmental pollution. Therefore, there is an urgent need for a filtering device for cold rolling oil processing that is efficient and can effectively filter out iron filings in cold rolling oil. Utility Model Content

[0004] In view of the above problems, the utility model provides a filtering device for cold rolling oil processing.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a filtering device for cold rolling oil processing, including a filter tank and a filter cover plate, the upper end of the filter tank is fitted with the lower end of the filter cover plate, the filter tank includes a filter tank body, the filtering device for cold rolling oil processing also includes a rotating adsorption filtering mechanism and a fixed adsorption filtering mechanism, the rotating adsorption filtering mechanism includes a rotating frame, an elastic member, a magnetic rod assembly and a variable speed motor, the upper end of the rotating frame is detachably connected to the variable speed motor, the magnetic rod assembly is detachably connected to the rotating frame through an elastic member, and the fixed adsorption filtering mechanism is installed on the inner side of the filter tank body.

[0006] Preferably, the fixed adsorption and filtering mechanism comprises an electromagnet magnetic attraction member and a fixed support portion, the length direction of the electromagnet magnetic attraction member is vertical, and the electromagnet magnetic attraction member and the fixed support portion are slidably connected.

[0007] Preferably, the magnetic bar assembly comprises a magnetic bar and a slider, the length direction of the magnetic bar is vertical, and the magnetic bar and the slider are detachably connected.

[0008] Preferably, the rotating frame comprises a slide groove portion and a rotating shaft, the slide groove portions are multiple in number, the length direction of the rotating shaft is vertical, and the multiple slide groove portions are evenly distributed around the circumference of the rotating shaft.

[0009] Preferably, the elastic member is a spring, and the elastic member includes a first spring and a second spring, and the length of the first spring is greater than the length of the second spring.

[0010] Preferably, the filtering device for cold rolling oil processing also includes a first filter screen and a second filter screen, the first filter screen is located at the upper end of the second filter screen, the rotating adsorption filtering mechanism is located between the first filter screen and the second filter screen, the first filter screen is provided with a plurality of filter holes one, the second filter screen is provided with a plurality of filter holes two, and the aperture of the filter hole one is larger than the aperture of the filter hole two.

[0011] Preferably, the first filter screen and the second filter screen are both magnetic filter screens.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] (1) The magnetic bar assembly is detachably connected to the rotating frame through an elastic member, and the speed of the variable speed motor can be adjusted, so that the magnetic bar assembly can continuously move during the process of adsorbing iron chips, and can adsorb more iron chips in the cold rolling oil. The movement range of the magnetic bar assembly is expanded, and the filtering effect of iron chips impurities in the cold rolling oil is good. At the same time, since the iron chips have a certain dead weight, when the rotating frame rotates, the iron chips are affected by the centrifugal force and move to the fixed adsorption and filtering mechanism. Through the cooperation of the fixed adsorption and filtering mechanism and the rotating adsorption and filtering mechanism, the adsorption effect of iron chips is good, the filtering time is saved, the filtering efficiency is high, and the iron chips in the cold rolling oil can be effectively filtered out;

[0014] (2) The electromagnet magnetic attraction part is slidably connected to the fixed support part. When the electromagnet magnetic attraction part is not powered, the iron filings will automatically fall off, making it easy to clean the iron filings after the filtration is completed;

[0015] (3) Both the first filter and the second filter are magnetic filters. The first filter plays a certain role in preliminary filtering and adsorption of iron filings, preventing larger iron filings from falling into the first filter and causing damage to the inner wall of the filter tank during rotation.

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] Example 1

[0034] Combine the following Figures 1 to 7 Specifically describe the filtering device for cold rolling oil processing, such as Figure 1 and Figure 2 As shown, a filtering device for cold rolling oil processing includes a filter tank 1 and a filter cover plate 4, the upper end of the filter tank 1 is attached to the lower end of the filter cover plate 4, the filter tank 1 includes a filter tank body 11, and the filtering device for cold rolling oil processing also includes a rotating adsorption filter mechanism 2 and a fixed adsorption filter mechanism 3, as shown in FIG. Figure 3 and Figure 4As shown, the rotating adsorption and filtering mechanism 2 includes a rotating frame 21, an elastic member 24, a magnetic rod assembly 22 and a variable speed motor 23. The upper end of the rotating frame 21 is detachably connected to the variable speed motor 23. The magnetic rod assembly 22 is detachably connected to the rotating frame 21 through the elastic member 24. The fixed adsorption and filtering mechanism 3 is installed on the inner side of the filter tank body 11.

[0035] like Figure 1 and Figure 7 As shown, the fixed adsorption and filtering mechanism 3 includes an electromagnet magnetic attraction member 31 and a fixed support portion 32. The length direction of the electromagnet magnetic attraction member 31 is vertical, and the electromagnet magnetic attraction member 31 and the fixed support portion 32 are slidably connected.

[0036] like Figure 5 and Figure 6 As shown, the magnetic bar assembly 22 includes a magnetic bar 27 and a slider 28. The magnetic bar 27 is vertical in length, and the magnetic bar 27 and the slider 28 are detachably connected.

[0037] like Figure 5 As shown, the rotating frame 21 includes a slide groove portion 25 and a rotating shaft 26 . There are multiple slide groove portions 25 . The length direction of the rotating shaft 26 is vertical. The multiple slide groove portions 25 are evenly distributed around the circumference of the rotating shaft 26 .

[0038] The variable speed motor 23 is detachably connected to the upper end of the rotating shaft 26 .

[0039] like Figure 4 As shown, the elastic member 24 is a spring, and the length of the elastic member 24 varies. The elastic member 24 includes spring one and spring two, and the length of spring one is greater than the length of spring two. During rotation, the movement trajectories of different magnetic bar assemblies 22 are cylinders with different inner diameters. The different lengths of the elastic member 24 ensure that the iron filings at different locations away from the axis of the filter tank 1 can fit as closely as possible with different magnetic bar assemblies 22.

[0040] like Figure 1 As shown, the filtering device for cold rolling oil processing also includes a first filter screen 5 and a second filter screen 6. The first filter screen 5 is located at the upper end of the second filter screen 6. The rotary adsorption filtering mechanism 2 is located between the first filter screen 5 and the second filter screen 6. The first filter screen 5 is provided with a plurality of filter holes 1, and the second filter screen 6 is provided with a plurality of filter holes 2. The aperture of the filter hole 1 is larger than the aperture of the filter hole 2.

[0041] The first filter screen 5 and the second filter screen 6 are both magnetic filter screens.

[0042] like Figure 1 As shown, the filter tank 1 further includes a liquid outlet 12 , which is located at the lower end of the filter tank body 11 , and the outer side of the liquid outlet 12 is connected to the one-way valve, and a liquid inlet is provided at the upper end of the filter cover plate 4 .

[0043] Working principle of the filter device for cold rolling oil processing:

[0044] The cold rolling oil to be processed is injected from the liquid inlet at the upper end of the filter cover plate 4, and the cold rolling oil to be processed passes through the second filter screen 6 and enters the cavity of the filter tank body 11 where the fixed adsorption filter mechanism 3 is located. The variable speed motor 23 is started, and the variable speed motor 23 performs variable speed rotation motion, thereby driving the multiple slide groove parts 25 to perform circular motion through the rotating shaft 26. Since the speed of the variable speed motor 23 is variable, the centrifugal force exerted on the magnetic rod assembly 22 will also change. Since the magnetic rod assembly 22 is slidably connected to the slide groove part 25 through the elastic member 24, the magnetic rod assembly 22 will slide relatively, thereby expanding the filtering and adsorption range for iron filings and improving the filtering and adsorption efficiency. At the same time, part of the iron filings moves to the inner wall edge of the filter tank body 11 under the action of centrifugal force. At this time, the electromagnet magnetic suction member 31 detachably mounted on the fixed support part 32 adsorbs this part of the iron filings, thereby adsorbing and filtering the iron filings in the cold rolling oil, and the cold rolling oil that meets the requirements flows out through the liquid outlet 12 to proceed to the next step.

[0045] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
