Description

Technical Field

[0001] The present invention belongs to the technical field of vertical mill type electrical energy-saving fans, and particularly relates to a vertical mill type electrical energy-saving fan with a replaceable air filter element quickly. Background Art

[0002] The air filter element of a vertical mill type electrical energy-saving fan is a component for filtering dust and other impurities in the air entering the fan. It is crucial for maintaining the normal operation of the fan and extending its service life. Therefore, it can be known that the existing vertical mill type electrical energy-saving fans basically meet people's usage requirements, but there are still the following problems.

[0003] When the vertical mill type electrical energy-saving fan is in long-term use, the filter element in the vertical mill type electrical energy-saving fan filters dust and other impurities in the air. During the long-term filtering process, dust and other impurities may accumulate in the filter element. When the filter element accumulates in the filter element, it may cause the filter element to be blocked, resulting in a decline in the filtering effect, thereby affecting the normal use of the vertical mill type electrical energy-saving fan. Therefore, it is necessary to replace the filter element in the vertical mill type electrical energy-saving fan. When replacing the filter element, the operator may need to stop the vertical mill type electrical energy-saving fan. Then, the operator removes the filter installed at the air inlet of the vertical mill type electrical energy-saving fan, then takes out the filter element in the filter, then the operator installs a new filter element in the filter, and then installs the filter with the new filter element at the air inlet of the vertical mill type electrical energy-saving fan. However, since there are many replacement steps during the replacement, it may cause the operator to take a long time to replace the filter element, which may affect the operation of the equipment and the production of the factory. For this reason, we propose a vertical mill type electrical energy-saving fan with a replaceable air filter element quickly. Summary of the Invention

[0004] The present invention provides a vertical mill type electrical energy-saving fan with a replaceable air filter element quickly. After the operator installs a new filter element in the filter cavity, the operator removes the old filter cavity from between the first connecting pipe and the second connecting pipe, and then installs the filter cavity with the new filter element between the first connecting pipe and the second connecting pipe again, which is convenient for the operator to quickly replace the filter element, shortens the pause time of the equipment, and improves the convenience of the operator's replacement.

[0005] To achieve the above object, the present invention provides the following technical solution: A vertical mill type electrical energy-saving fan with a quickly replaceable air filter element, comprising a quick assembly component arranged at the corresponding air inlet of the vertical mill type electrical energy-saving fan main body. The quick assembly component includes a first connecting pipe, a filtering chamber, and a second connecting pipe. One end of the first connecting pipe is movably and sealingly connected to the air inlet, the other end of the first connecting pipe is threadedly installed with the filtering chamber, and the other end of the filtering chamber is threadedly installed with the second connecting pipe; Rotating rods are arranged above the quick assembly component, and collar rings are sequentially sleeved on the surface of each rotating rod. A second connecting rod and a first connecting rod are fixedly connected to the surface of the collar ring. Among them, a fixing sleeve respectively sleeved on the surfaces of the second connecting pipe and the first connecting pipe is fixed at the end of the first connecting rod, the second connecting rod is fixed on the filtering chamber, and a filter element is threadedly installed in the middle of the cavity of the filtering chamber.

[0006] Furthermore, sealing plates are symmetrically attached to both end portions of the filtering chamber, and the sealing plates and the filtering chamber are fixedly connected through positioning pins passing through. A limiting block is arranged at the end of the positioning pin.

[0007] Furthermore, second spring grooves are respectively opened at the ends of the positioning pins, and a limiting block and a second spring are respectively arranged inside the second spring grooves. Both end portions of the second spring abut between the two groups of limiting blocks.

[0008] Furthermore, the fixing sleeve is symmetrically fixed on the surface of the second connecting pipe and / or the first connecting pipe by bolts in a threaded manner, and the fixing sleeve close to the rotating rod side is fixedly connected to the first connecting rod.

[0009] Furthermore, first spring grooves are respectively fixed at both end portions of the filtering chamber. A positioning rod passing through the filtering chamber and the second connecting pipe and a first spring respectively abutting between the surface of the positioning rod and the inner wall of the first spring groove are respectively arranged inside the first spring grooves. Rotating blocks fitting on the first spring grooves are respectively fixed on the surface of the positioning rod.

[0010] Furthermore, a handle is arranged between the two groups of rotating blocks, and rotating shafts penetrate through both end portions of the handle. Both end portions of the rotating shafts are fixed on a pull rod, and another rotating shaft penetrating through the rotating block is fixed at the end of the pull rod.

[0011] Furthermore, limiting rods penetrate through the surface of the fixing sleeve, and the limiting rods are respectively fixed on the outer side walls of the second connecting pipe and the first connecting pipe.

[0012] The beneficial effects of the present invention are:

[0013] 1. The vertical mill type electric energy-saving fan with a quickly replaceable air filter element is provided with a second connecting rod, a collar and a rotating rod. After the filter chamber is no longer fixed to the first connecting pipe and the second connecting pipe, the operator pushes the filter chamber equipped with a new filter element to move. The filter chamber equipped with the new filter element drives the second connecting rod to move, and the second connecting rod drives the collar to rotate on the surface of the rotating rod, so that the filter chamber with the old filter element inside is moved away from between the first connecting pipe and the second connecting pipe, thereby installing the filter chamber with the new filter element inside between the first connecting pipe and the second connecting pipe, facilitating the operator to replace the filter element, reducing the time for the operator to turn off the main body of the vertical mill type electric energy-saving fan, and improving the convenience of replacement for the operator.

[0014] 2. The vertical mill type electric energy-saving fan with a quickly replaceable air filter element is provided with a sealing plate, a positioning pin and a limiting block. The positioning pin penetrates through the filter chamber and the sealing plate, and then the limiting block blocks the surface of the filter chamber to install the sealing plate on the filter chamber. When the filter chamber is not in use, it is convenient to block both sides of the filter chamber to prevent dust or other sundries from falling into the unused filter chamber, improving the usability of the filter chamber.

[0026] In order to further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail with reference to the accompanying drawings as follows.

[0027] Embodiment:

[0028] Please refer to Figure 1 - Figure 9 , a vertical mill type electrical energy-saving fan with a quickly replaceable air filter element, including a quick assembly component arranged at the air inlet 2 corresponding to the vertical mill type electrical energy-saving fan main body 1. The quick assembly component includes a first connecting pipe 3, a filter chamber 4, a filter element 5 and a second connecting pipe 6. One end of the first connecting pipe 3 is movably and hermetically connected to the air inlet 2, the other end of the first connecting pipe 3 is threadedly installed with a filter chamber 4, and a filter element 5 is threadedly installed in the middle of the filter chamber 4. The other end of the filter chamber 4 is threadedly installed with a second connecting pipe 6. Rotating rods 12 are arranged above the second connecting pipe 6, the filter chamber 4 and the first connecting pipe 3, and collars 11 are sequentially sleeved on the surface of the rotating rods 12. Second connecting rods 10 and first connecting rods 9 are respectively welded on the surface of the collars 11. The end of the first connecting rod 9 is welded with fixed sleeves 13 respectively sleeved on the surfaces of the second connecting pipe 6 and the first connecting pipe 3. The second connecting rod 10 is welded on the filter chamber 4, as Figure 7 shown.

[0029] Specifically, an air inlet 2 is welded to one end of the vertical mill type electrical energy-saving fan main body 1, and a first connecting pipe 3 is threadedly installed on the surface of the air inlet 2.

[0030] Working principle: When the operator needs to replace the old filter element 5, the operator first picks up the new filter element 5 and installs the new filter element 5 into the filter chamber 4 arranged outside the first connecting pipe 3 and the second connecting pipe 6. After the new filter element 5 is installed in the outer filter chamber 4, the operator disassembles the filter chamber 4 installed between the first connecting pipe 3 and the second connecting pipe 6, so that the first connecting pipe 3 and the second connecting pipe 6 are no longer fixedly connected to the filter chamber 4. Then the operator pushes the filter chamber 4 with the new filter element 5 installed inside, so that the filter chamber 4 drives the collar 11 to rotate on the surface of the rotating rod 12 through the second connecting rod 10. And the collar 11 rotates on the surface of the rotating rod 12, so that the second connecting rod 10 drives the filter chamber 4 with the old filter element 5 installed in the middle to move, so that the filter chamber 4 with the old filter element 5 installed in the middle is moved out from between the first connecting pipe 3 and the second connecting pipe 6, and the filter chamber 4 with the new filter element 5 installed in the middle is moved to between the first connecting pipe 3 and the second connecting pipe 6. Subsequently, the operator threadedly installs the filter chamber 4 with the new filter element 5 installed in the middle to the first connecting pipe 3 and the second connecting pipe 6. Then the operator takes out the old filter element 5 from the filter chamber 4. When the operator replaces the filter element 5, it is no longer necessary for the operator to close the vertical mill type electric energy-saving fan main body 1 for a long time, reducing the closing time of the vertical mill type electric energy-saving fan main body 1 for the operator and improving the convenience of replacement for the operator. In this technical solution, the vertical mill type electric energy-saving fan main body 1, the air inlet 2, the first connecting pipe 3, the filter chamber 4, the filter element 5 and the second connecting pipe 6 are widely used in this field, and their structures and principles are well-known to those skilled in the art, so no further details will be given here.

[0031] Further explanation, as Figure 3 and Figure 9As shown, sealing plates 23 are symmetrically fitted on both side ends of the filter chamber 4, and positioning pins 18 are passed through the sealing plates 23 and the filter chamber 4 on all sides. The ends of the positioning pins 18 are elastically connected to limit blocks 20 that abut against the surface of the filter chamber 4. Second spring grooves 21 are opened on the ends of the positioning pins 18, and the second spring grooves 21 are respectively provided with limit blocks 20 and second springs 24. Both side ends of the second spring 24 abut between the two groups of limit blocks 20. When the filter chamber 4 is taken out from between the first connecting tube 3 and the second connecting tube 6, and the old filter element 5 is taken out from the filter chamber 4, the operator then takes the sealing plates 23 and inserts the sealing plates 23 into both sides of the filter chamber 4. The operator then takes the positioning pins 18 and presses the limit blocks 20 set at the ends of the positioning pins 18. After the limit blocks 20 are squeezed, the limit blocks 20 slide in the second spring grooves 21, and the limit blocks 20 are pressed in the second spring grooves 21. During sliding, the limit block 20 squeezes the second spring 24, causing the second spring 24 to undergo elastic deformation. After the second spring 24 undergoes elastic deformation, the second spring 24 avoids the limit block 20, allowing the limit block 20 to enter the second spring groove 21. Subsequently, the operator passes the positioning pin 18 through the filter chamber 4 and the sealing plate 23. After the positioning pin 18 passes through the filter chamber 4 and the sealing plate 23, the limit block 20 is no longer pressed by the filter chamber 4 and the sealing plate 23, and the limit block 20 no longer squeezes the second spring 24. The elastic deformation of the second spring 24 is restored, and the second spring 24 pushes the limit block 20 to move, causing the limit block 20 to move out of the second spring groove 21, and the limit block 20 is attached to the surface of the filter chamber 4, thereby installing the sealing plate 23 on both sides of the filter chamber 4. By shielding both sides of the filter chamber 4, dust or other debris is prevented from falling into the unused filter chamber 4, thereby improving the usability of the filter chamber 4.

[0032] Further explanation, such as Figure 7 As shown, two groups of fixing sleeves 13 are symmetrically arranged, and the two groups of fixing sleeves 13 are respectively sleeved on the surfaces of the second connecting tube 6 and the first connecting tube 3, and the two groups of fixing sleeves 13 are fixed to the surfaces of the second connecting tube 6 and the fixing sleeves 13 by bolt thread connection. The fixing sleeves 13 on the side close to the rotating rod 12 are fixed with the first connecting rod 9. When the operator needs to install the rotating rod 12 on the first connecting tube 3 and the second connecting tube 6, the operator first takes the fixing sleeves 13 and sleeves the two groups of fixing sleeves 13 on the surfaces of the second connecting tube 6 and the first connecting tube 3. Then, the operator installs the fixing sleeves 13 on the surfaces of the second connecting tube 6 and the first connecting tube 3 by bolt thread installation, so that the fixing sleeves 13 mount the rotating rod 12 on the first connecting tube 3 and the second connecting tube 6 through the first connecting rod 9.

[0033] Further explanation: first spring grooves 16 are respectively welded to the two side ends of the filter chamber 4, and the first spring grooves 16 are respectively provided with positioning rods 14 penetrating the filter chamber 4 and the second connecting tube 6 and first springs 17 respectively abutting between the surface of the positioning rod 14 and the inner wall of the first spring groove 16. Rotating blocks 15 that fit on the first spring grooves 16 are welded to the surfaces of the positioning rods 14. A handle 7 is provided between the two groups of rotating blocks 15, and rotating shafts 19 are penetrated at both side ends of the handle 7. Both side ends of the rotating shaft 19 are welded to the pull rod 8. Another rotating shaft 19 penetrating the rotating block 15 is welded to the end of the pull rod 8. When the operator separates the filter chamber 4 from the first connecting tube 3 and the second connecting tube 6, the operator pulls the handle 7. 7 The pull rod 8 is driven to move by the rotating shaft 19, and the pull rod 8 drives another rotating shaft 19 to move, and the other rotating shaft 19 drives the rotating block 15 to move. When the rotating block 15 moves, the rotating block 15 drives the positioning rod 14 to slide in the first spring groove 16, and when the positioning rod 14 slides in the first spring groove 16, the first spring groove 16 squeezes the first spring 17, so that the first spring 17 is elastically deformed. After the first spring 17 is elastically deformed, the first spring 17 avoids the positioning rod 14, so that the positioning rod 14 is moved out of the second connecting pipe 6 and the filter chamber 4, so that the positioning rod 14 no longer fixes the second connecting pipe 6 and the filter chamber 4, and it is convenient for the operator to move by pulling the two groups of positioning rods 14;

[0034] When the operator needs to install the filter chamber 4 between the first connecting tube 3 and the second connecting tube 6, the operator first pulls the handle 7, and the handle 7 drives the pull rod 8 to move through the rotating shaft 19, and the pull rod 8 drives another rotating shaft 19 to move, and the other rotating shaft 19 drives the rotating block 15 to move. When the rotating block 15 moves, the rotating block 15 drives the positioning rod 14 to slide in the first spring groove 16, and when the positioning rod 14 slides in the first spring groove 16, the first spring groove 16 squeezes the first spring 17, causing the first spring 17 to undergo elastic deformation. After the first spring 17 undergoes elastic deformation, the first spring 17 avoids the positioning rod 14, and the first spring 17 enters the first spring groove 16. Then the operator pushes the filter chamber 4, and the filter chamber 4 drives the positioning rod 14 to move through the first spring groove 16, so as to move the filter chamber 4 to the first connecting tube 3 and the second connecting tube 6. The first connecting tube 3 and the second connecting tube 6 are connected, and the positioning rod 14 is aligned with the through holes opened on the surfaces of the first connecting tube 3 and the second connecting tube 6. Then the operator releases the handle 7, and the handle 7 no longer restricts the pull rod 8 through the rotating shaft 19, and the pull rod 8 no longer restricts the rotating block 15 through another rotating shaft 19. After the rotating block 15 no longer squeezes the first spring 17 through the positioning rod 14, the elastic deformation of the first spring 17 is restored, and the first spring 17 pushes the positioning rod 14 to move, so that the positioning rod 14 is moved out of the first spring groove 16, and the positioning rod 14 passes through the second connecting tube 6 and the through holes opened on the surfaces of the first connecting tube 3, and the filter chamber 4 is pre-installed between the first connecting tube 3 and the second connecting tube 6 to prevent the filter chamber 4 from shaking between the first connecting tube 3 and the second connecting tube 6 when the operator installs the first connecting tube 3, the filter chamber 4 and the second connecting tube 6.

[0035] To further illustrate, the surface of the fixing sleeve 13 is penetrated by the limiting rod 22, and the limiting rod 22 is respectively welded on the outer side walls of the second connecting tube 6 and the first connecting tube 3. When the operator installs the fixing sleeve 13 on the surfaces of the second connecting tube 6 and the first connecting tube 3, the operator takes the fixing sleeve 13 and aligns the fixing sleeve 13 with the limiting rod 22 fixed on the surfaces of the first connecting tube 3 and the second connecting tube 6. Then, the operator pushes the fixing sleeve 13, and the through hole opened on the surface of the fixing sleeve 13 is sleeved on the surface of the limiting rod 22, so that the limiting rod 22 limits the fixing sleeve 13, so as to avoid the two groups of fixing sleeves 13 sliding on the surface of the second connecting tube 6 when the operator performs threaded installation on the two groups of fixing sleeves 13, thereby improving the convenience of installation by the operator.
