Description

Technical Field

[0001] This application belongs to the technical field of emulsion filtration, and particularly relates to a filter element assembly and an emulsion filtration device. Background Art

[0002] Emulsion can be used for cooling and lubricating rolls, etc. The used emulsion needs to be filtered by equipment such as a filter element before it can be put into use again. The filter element can be installed in the emulsion filtration device. The emulsion enters the emulsion filtration device and flows out of the emulsion filtration device into other devices after being filtered by the filter element of the emulsion filtration device.

[0003] Currently, one end of the filter element is sleeved with an annular sealing base. The outer peripheral wall of the sealing base is then matched with the installation groove for assembling the filter element in the emulsion filtration device. An annular protrusion also needs to be provided on the outer peripheral wall of the sealing base to achieve axial positioning relative to the installation groove. The sealing base plays a role in sealing and fixing the filter element. Therefore, it needs to be prepared with a relatively large volume, which correspondingly increases the overall preparation and maintenance costs. Moreover, if the sealing base ages and is damaged, it will affect the position of the filter element. The relatively large sealing base may also move, causing the emulsion circuit to be blocked, both of which will affect the normal operation of the filter element. The preparation, maintenance costs and reliability of the filter element-related equipment are not ideal enough. Summary of the Utility Model

[0020] In some embodiments, the cross section of the side wall of the mounting groove is circular, and the side wall of the mounting groove is in clearance fit with the outer peripheral wall of the open end.

[0021] Beneficial effects provided by one or more embodiments of the present application:

[0022] The filter element device has at least two barrel-shaped filter elements. The two axial ends of the filter element are respectively a closed end and an open end. The filter element can be abutted against the bottom surface of the installation groove provided in the emulsion filtration device through the open end to provide support for the filter element. A circular groove for cooperating with the annular seal is provided on the outer peripheral wall of the open end of the filter element. The outer peripheral wall of the annular seal is in sealing cooperation with the side wall of the installation groove, so that the filter element can be supported and fixed.

[0034] Next, the present application will be described in conjunction with the accompanying drawings:

[0035] Figure 1The structural schematic diagram of a filter element assembly in some or certain embodiments of the present application is shown. Referring to Figure 1 As can be seen, the embodiments of the present application provide a filter element assembly for assembling with at least two mounting grooves 101 of an emulsion filtering device, including:

[0036] A filter element 1, which is barrel-shaped and has a closed end 11 and an open end 12 at both axial ends respectively. An annular groove 121 surrounding the open end 12 is provided on the outer peripheral wall of the filter element 1, and the open end 12 is used to abut against the bottom surface 1011 of the corresponding mounting groove 101.

[0037] An annular seal 2, which is hermetically sleeved in the annular groove 121, and the outer peripheral wall is used for hermetic cooperation with the side wall 1012 of the mounting groove 101.

[0038] A fixing plate 3, which is detachably connected to the closed ends 11 of at least two filter elements 1 arranged side by side.

[0039] The filter element device has at least two barrel-shaped filter elements 1, and the axial ends of the filter element 1 are respectively a closed end 11 and an open end 12. The filter element 1 can abut against the bottom surface 1011 of the mounting groove 101 provided in the emulsion filtering device through the open end 12 to provide support for the filter element 1. An annular groove 121 for cooperating with the annular seal 2 is provided on the outer peripheral wall of the open end 12 of the filter element 1. The outer peripheral wall of the annular seal 2 is hermetically cooperated with the side wall 1012 of the mounting groove 101, so that the filter element 1 can be supported and fixed. The volume of the annular seal 2 will not be too large, which can reduce the sealing cost between the filter element 1 and the emulsion filtering device. And even if the annular seal 2 has problems such as aging and damage, the filter element 1 can still be supported by the abutment of the open end 12 and the bottom surface 1011 of the mounting groove 101. The small volume of the annular seal 2 is not easy to block the emulsion circuit, which can reduce the preparation and maintenance costs of the filter element 1 and the related emulsion filtering device, and the use reliability of the filter element 1 can also be improved. And the closed ends 11 of at least two filter elements 1 arranged side by side are all detachably connected to the fixing plate 3. Then, in addition to the support obtained by the filter element 1 through the abutment of the open end 12 and the mounting groove 101, the closed ends 11 of multiple filter elements 1 can also be jointly supported by the fixing plate 3. Both ends of each filter element 1 can be supported and positioned, preventing the filter element 1 from shifting due to seal aging and affecting the normal operation of the filter element 1. Similarly, it is beneficial to improve the working reliability of the filter element 1, and to a certain extent, solve the technical problems that the preparation, maintenance costs and reliability of the equipment related to the filter element 1 are not ideal enough.

[0040] It should be noted that at least two mounting grooves 101 can be provided on the base 10 of the emulsion filtering device, and each mounting groove 101 can cooperate with the open end 12 of the corresponding filter element 1. The emulsion filtering device usually also has through holes for emulsion that communicate with the mounting grooves 101 to receive the emulsion flowing out from different pipelines or other devices. After the emulsion enters the mounting groove 101, it enters the open end 12 to be filtered and purified by the filter element 1. Figure 1 The arrow in

[0041] In some embodiments, the fixing plate 3 and the closed end 11 are detachably connected by fasteners 4.

[0042] Using the fasteners 4 to achieve the detachable connection between the fixing plate 3 and the closed end 11 is convenient to implement, easy to operate, and has a low maintenance cost.

[0043] In some embodiments, the fastener 4 is columnar and is sequentially inserted to connect the fixing plate 3 and the closed end 11. The filter element assembly further includes a buffer pad 5 sleeved on the fastener 4 and located between the fixing plate 3 and the closed end 11 of the filter element 1.

[0044] It is convenient to operate, and the buffer pad 5 can play a buffering role to prevent the two closed ends 11 from contacting and wearing with the fixing plate 3, which is beneficial to improving the service life and reliability of the filter element assembly.

[0045] In some embodiments, the fixing member can be a fixing bolt. The fixing plate 3 can be provided with a light hole, and the closed end 11 can be provided with a threaded blind hole. After the fixing bolt is movably inserted into the fixing plate 3, it is then inserted into the threaded blind hole to be in threaded cooperation with the closed section. It is convenient for disassembly and assembly and easy to maintain.

[0046] In some embodiments, a corresponding buffer pad 5 can be provided between the closed end 11 of each filter element 1 and the fixing plate 3, and the buffer pad 5 can be a colloidal buffer pad 5. It is easy to obtain and prepare.

[0047] In some embodiments, the fixing plate 3 is an annular plate whose axis extends in the same direction as the axis of the filter element 1, and a plurality of filter elements 1 are detachably connected to the fixing plate 3 at intervals along the circumferential direction of the annular plate. It is beneficial to the uniform purification and recovery of the emulsion.

[0048] In some embodiments, the fixing plate 3 can also be set as a circular plate of different shapes or set as a plate-like structure of other shapes according to requirements, and through holes for the emulsion to flow through can also be provided on the fixing plate 3.

[0049] Figure 2 The structural schematic diagram of a filter element in some embodiments or certain embodiments of the present application is shown. Refer to Figure 2It can be known that in some embodiments, at least two annular grooves 121 are provided on the outer peripheral wall of the open end 12, and each annular groove 121 is provided with a corresponding annular seal 2, and the annular seal 2 is an O-ring.

[0050] At least two annular grooves 121 are provided on the outer peripheral wall of the open end 12, and a corresponding annular seal 2, which can be an O-ring, is fitted in each annular groove 121, which can improve the sealing effect, and the preparation cost of the O-ring is relatively low, which is beneficial to reducing the preparation and maintenance costs of the filter element assembly.

[0051] Figure 3 The bottom view of a filter element in some embodiments of the present application is shown. In combination with Figure 2 and Figure 3 , in some embodiments, the filter element 1 includes a barrel body portion 13, a sealing head portion and an annular bottom portion. The barrel body portion 13 is in a cylindrical shape, the sealing head portion is covered at one end of the barrel body portion 13 and is configured as the closed end 11, and the annular bottom portion is coaxially connected to the barrel body portion 13 and is configured as the open end 12. The filter element 1 adopting the structure described in this paragraph is convenient for the preparation of the filter element 1 and to achieve the cooperation with the emulsion filtering device.

[0052] In some embodiments, the barrel body portion 13 is in a conical cylindrical shape, and the sealing head portion is provided at the end with a smaller diameter of the barrel body portion 13. Then the annular bottom portion configured as the open end 12 is provided at the end with a larger diameter of the barrel body portion 13. The filtering effect of the filter element 1 is better, and the annular bottom portion can provide better support for the filter element 1.

[0053] In some embodiments, one end of the annular bottom portion is fixedly bonded and welded to the end with a larger diameter of the barrel body portion 13. This is beneficial to improving the overall stability of the filter element 1. The sealing head portion may be provided with a threaded hole 111 threadedly connected to the fastener 4.

[0054] Figure 4 The present application is shown Figure 2 The enlarged schematic view of the B position of the filter element in Figure 5 The present application is shown Figure 2 The enlarged schematic view of the C position of the filter element in Figures 2 to 5 , in some embodiments, the barrel body portion 13 includes weft strips 131 spirally wound into a spring structure and warp strips 132 welded to the weft strips 131. A plurality of warp strips 132 are spaced apart along the circumferential direction of the spring structure, and the length direction of the warp strips 132 extends along the axial direction of the spring structure. The strength and filtering effect of the filter element 1 are better, which is beneficial to improving the use reliability of the filter element 1.

[0055] In some embodiments, the sealing head portion or the closure 11 can be a structure such as a cover plate, and the annular bottom portion can be in an annular plate shape. This is convenient for the preparation of the filter element 1.

[0056] Based on the same inventive concept, the present application also provides an emulsion filtering device, which includes:

[0057] A base 10, provided with at least two mounting grooves 101 arranged side by side, and emulsion through holes 102 corresponding to and communicating with the bottom surfaces 1011 of each mounting groove 101.

[0058] The filter element assembly as described above, the open end 12 of each filter element 1 abuts against the bottom surface 1011 of the corresponding mounting groove 101, and the outer peripheral wall of the annular seal 2 is in sealing fit with the side wall 1012 of the mounting groove 101.

[0059] A housing 30, sleeved on the base 10 and having a receiving cavity 20 for receiving the filter element assembly.

[0060] For the structure of the filter element assembly and its corresponding technical effects, reference can be made to the foregoing, and details will not be elaborated here. The base 10 of the emulsion filtering device is provided with mounting grooves 101 and is matched with the filter element assembly, having a good sealing effect and a simple sealing structure. The housing 30 and the base 10 can form a receiving cavity 20 for receiving the filter element assembly. The base 10 can divide the receiving cavity 20 of the housing 30 into two parts. The housing 30 can be respectively provided with an emulsion inlet 301 and an emulsion outlet 302 on both sides of the base 10. The emulsion enters from the emulsion inlet 301, then enters the filter element 1 through the emulsion through hole 102 of the base 10, and can flow out from the emulsion outlet 302 and be introduced into the required equipment after passing through the filter element 1.

[0061] In some embodiments, the cross-section of the side wall 1012 of the mounting groove 101 is circular, and the side wall 1012 of the mounting groove 101 is in clearance fit with the outer peripheral wall of the open end 12. It has a good matching effect with the filter element 1 and is convenient for the installation of the filter element 1.

[0062] In some embodiments, the axes of at least two mounting grooves 101 can extend along the same direction. The emulsion through holes 102 corresponding to the mounting grooves 101 can be coaxially arranged with the mounting grooves 101, and each emulsion through hole 102 penetrates through the base 10. It is convenient for the flow and filtration of the emulsion.

[0063] In some embodiments, after adopting the filter element assembly and the emulsion filtering device described in the present application, on the premise of ensuring the sealing effect, the volume of the seal is greatly reduced, and the annular seal 2 is set as an O-ring. The cost of a single seal is only 5 yuan. Although the number of seals supporting each filter element 1 changes from 1 to 2, the cost is still greatly reduced, saving 30,240 yuan in spare part costs per year: 3×18×150×4 - 3×18×2×5×4 = 30,240 yuan.

[0064] Moreover, after adopting the filter element assembly and the emulsion filtering equipment described in the present application, the wall thickness of the annular seal 2 can be only 4 mm, and even if it corrodes and falls off, it will not cause the problem of pipeline blockage. It saves about 12,500 yuan of pipeline cleaning man-hour cost every year. And if the filter element 1 is not tightly sealed, the cleanliness of the emulsion will be reduced. The falling off of the seal of the filter element 1 causes the blockage of the emulsion pipeline and affects the emulsion flow rate. Both the cleanliness of the emulsion and the emulsion flow rate determine the surface quality of the strip steel products in the steel mill. 300 tons of downgraded products are caused by the problems of emulsion cleanliness and emulsion flow rate every year, and the benefit affected per ton of steel is 150 yuan. Therefore, the new technology creates a benefit of 300 * 150 = 45,000 yuan every year.

[0065] In summary, after adopting the newly designed filter element 1, the benefit created every year is 30,240 + 12,500 + 45,000 = 87,740 yuan.

[0066] It should be noted that the coaxiality involved in the present application means that the axes of related components extend in the same direction. The outer peripheral wall involved in the present application is the peripheral wall with a larger diameter of a ring structure or a cylindrical structure.
