Description

Technical Field

[0001] The utility model relates to a die-casting filter with a convenient filter element replacement, belonging to the field of die-casting filters. Background Art

[0002] In current industrial production, liquid filtration is a crucial link and is widely used in many fields such as chemical, pharmaceutical, food and water treatment. As an important equipment, the performance of die-casting filter directly affects the filtration effect and production efficiency. However, the existing die-casting filters generally have some shortcomings in terms of filter element replacement and connection stability, which limit the user experience and overall performance of the equipment.

[0003] First, existing die-cast filters are often complex in design and cumbersome in operation when it comes to filter element replacement. Traditional filter element replacement usually requires the removal of a large number of fasteners, and even requires professionals to use special tools to complete it, which not only increases maintenance costs, but also prolongs downtime and reduces production efficiency. In addition, the complex replacement process also increases the risk of operating errors and may cause unnecessary damage to the equipment. Secondly, existing die-cast filters also have certain problems in terms of the stability of the connection. Due to the complex and changeable working environment, the connection between the filter and the equipment is often affected by external factors such as vibration and impact, and is prone to loosening and leakage. This not only affects the filtering effect, but may also pose a threat to production safety. Utility Model Content

[0023] See also Figures 1 to 3 A die-cast filter for convenient replacement of filter elements comprises a filter body 1, a connecting plate 2 fixedly connected to the left end and the right end of the filter head of the filter body 1, a connecting pipe 3 fixedly connected to the other side of the connecting plate 2, and a connecting flange 4 fixedly connected to the other end of the connecting pipe 3. A supporting structure for improving the stability of the connection is provided on the outer side of the connecting pipe 3.

[0024] like Figure 1 As shown, the supporting structure includes a fixing ring 5 fixedly connected to the outside of the connecting tube 3, a frame 6 fixedly connected to the top and bottom of the fixing ring 5, a threaded shaft 7 rotatably connected to the inside of the frame 6, a threaded block 8 threadedly connected to the outside of the threaded shaft 7, a fixing plate 9 fixedly connected to the front and back sides of the threaded block 8, and an elastic component arranged between opposite side walls of the fixing plates 9 on the front and rear sides.

[0025] It should be noted that four rotating holes are opened on the inner side of the connecting plate 2 , and the inner sides of the four rotating holes are rotatably connected with bolts 10 , and the connecting plate 2 is fixedly connected to the filter head of the filter body 1 through the bolts 10 .

[0026] The bottom end of the upper threaded shaft 7 is rotatably connected to the inner bottom wall of the upper frame body 6 , and the top end of the lower threaded shaft 7 is rotatably connected to the inner top wall of the lower frame body 6 .

[0027] The top end of the upper threaded shaft 7 is fixedly connected to a twist cap 11, and the bottom end of the lower threaded shaft 7 is also fixedly connected to the twist cap 11. The top end of the upper threaded shaft 7 movably passes through the inner top wall of the upper frame 6 and extends to the inner side of the center of the upper twist cap 11 and is fixedly connected to the upper twist cap 11. The bottom end of the lower threaded shaft 7 movably passes through the inner bottom wall of the lower frame 6 and extends to the inner side of the center of the lower twist cap 11 and is fixedly connected to the lower twist cap 11.

[0028] The elastic component includes a mounting shell 12 fixedly connected between opposite side walls of the front and rear fixing plates 9, three elastic telescopic rods 13 fixedly connected to the inner side of the mounting shell 12, and a support plate 14 fixedly connected between the other ends of the three elastic telescopic rods 13.

[0029] The three upper elastic telescopic rods 13 are fixedly connected to the inner top wall of the upper mounting shell 12, and the three upper elastic telescopic rods 13 are arranged equidistantly in sequence along the left-right direction, and the three lower elastic telescopic rods 13 are fixedly connected to the inner bottom wall of the lower mounting shell 12, and the three lower elastic telescopic rods 13 are arranged equidistantly in sequence along the left-right direction.

[0030] The bottom of the upper support plate 14 and the upper surface of the lower support plate 14 are both fixedly connected with a buffer pad 15 , and the length and width of the buffer pad 15 are respectively equal to the length and width of the support plate 14 .

[0031] The working principle of the above embodiment is:

[0032] The bolts 10 connected by rotating in the four rotating holes opened on the inner side of the connecting plate 2 serve as fastening elements between the connecting plate 2 and the filter head of the filter body 1, allowing the user to quickly separate and reassemble the two through a simple rotating operation. When the filter element needs to be replaced, the user only needs to loosen the bolts 10, remove the connecting plate 2 and its attached connecting pipe 3, connecting flange 4 and other components from the filter body 1, and then replace the filter element;

[0033] The fixing ring 5 is firmly connected to the outside of the connecting pipe 3 to provide basic support for the entire supporting structure. The threaded shaft 7 is connected to the inside of the frame 6 by rotation, allowing the user to drive the rotation of the threaded shaft 7 by rotating the twist cap 11. As the threaded shaft 7 rotates, the threaded block 8 threadedly connected to it will move axially, thereby driving the lifting and lowering adjustment of the fixing plate 9 and the elastic component, and making the elastic component contact the connecting part, thereby supporting the connecting part. The elastic component is composed of a mounting shell 12, an elastic telescopic rod 13 and a support plate 14. The elastic telescopic rod 13 is the main elastic element, which can produce corresponding deformation when subjected to external force to absorb impact and vibration, thereby protecting the filter from external environmental factors. The buffer pad 15 on the support plate 14 further enhances the stability and buffering effect of the support, ensuring a close fit and smooth operation between the filter and the equipment.

[0034] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0035] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
