[0010] As a preferred embodiment of the above technical solution, a guide groove is provided on the outer side of the top end of the barrier cover, a round hole is provided on the top end of the column, and the plug-in rod passes through the inside of the round hole.

[0011] The present invention also provides a filtering method of an industrial filtering device, comprising the following steps: Step 1: Assemble the device and install the filter element: Place the lower shell in the designated position, install the chassis at the bottom of the inner wall of the lower shell, and ensure that it is stable, install the reverse impact cleaning assembly on the top of the chassis, and then install the filter element on the top of the chassis and outside the reverse impact cleaning assembly, ensuring that the filter element fits tightly against the chassis, and then install the fixing assembly to ensure that the top of the filter element is fixed.

[0012] Step 2: Start the filter device: open the air inlet or liquid inlet of the industrial filter device to allow the gas or liquid to be filtered to enter the lower shell. The fluid to be filtered is pressurized to enter the top of the filter element through the guide structure, and the liquid or gas at the bottom is evenly distributed to the outer surface of the filter element.

[0015] Step 5: Maintenance and inspection of the device: Check the filter element's filtration efficiency and integrity regularly and replace it if necessary; Check the moving parts of the reverse impact cleaning assembly to ensure that they are functioning properly; Clean the chassis and bottom of the lower shell of the device to prevent dust accumulation from affecting the filtering effect; Check the bolt structure and sealing parts to ensure the sealing and stability of the device.

Automated cleaning reduces manual intervention, reduces maintenance costs and time, and has good energy-saving effects and environmental protection performance; (2) It achieves efficient and automated cleaning effects, reduces cleaning blind spots, and reduces maintenance costs.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Embodiment 1: The present invention provides an industrial filtration device, such as Figures 1 to 11As shown, it includes: a lower shell 1, an upper shell 2 is installed on the top of the lower shell 1 through a bolt structure, a guide structure 3 is welded inside the upper shell 2, the guide structure 3 is composed of a limit ring, a connecting rod and a barrier ring, the limit ring is fixedly installed inside the upper shell 2, connecting rods are equidistantly formed in one piece inside the upper shell 2, and barrier rings are fixedly connected between the outer sides of multiple connecting rods, a chassis 4 is fixedly installed inside the lower shell 1, a fixing component 5 is fixedly installed on the edge of the top tube of the chassis 4, a filter element 6 is installed at the top of the chassis 4 at a position inside the fixing component 5, and a reverse impact cleaning component 7 is installed at the top of the chassis 4 at a position inside the filter element 6. The reverse impact cleaning component 7 includes a fixed installation A plurality of concave covers 77 are mounted in the middle of the filter element 6, and the number of the concave covers 77 is set to five in total. A movable plate 78 is movably connected to the inside of the plurality of concave covers 77 up and down, and the number of the movable plates 78 is set to five in total. A guide plate 79 is fixedly mounted on the top of the movable plate 78, and a rotating ring 710 is rotatably connected to the outer side of the guide plate 79. The top of the movable plate 78 and the bottom of the guide plate 79 are connected by a pipeline, and the number of the rotating rings 710 is set to five in total. Nozzles 711 are equidistantly penetrated and connected to the top and bottom of the outer surface of the rotating ring 710, and a movable block 712 is slidably connected to the middle of the outer side of the guide plate 79, and a rounded corner is provided on the outer side of the movable block 712.

[0021] like Figures 5 to 7 As shown, multiple mounting posts 71 are fixedly installed between the outer sides of multiple concave covers 77, and a barrier disc 72 is integrally formed at the bottom of the outer surface of the mounting post 71. The outer side of the barrier disc 72 and the inner wall of the filter element 6 fit each other, and multiple convergence covers 73 are embedded and installed on the top of the barrier disc 72. A drainage pipe 74 is fixedly installed at the bottom of the convergence cover 73. A positioning sleeve 76 is rotatably connected inside the barrier disc 72, and a stirring blade 75 is fixedly installed on the outer side of the positioning sleeve 76. Since the convergence hood 73 converges the liquid or gas, the flow rate or pressure of the gas when it is discharged along the drainage tube 74 is increased, which makes it easier to drive the stirring blade 75 to rotate. When the stirring blade 75 rotates, it can drive the positioning sleeve 76 to rotate, which changes the difficulty of rotating the positioning sleeve 76, and under the action of the blocking plate 72, the gas and liquid are blocked, so that the gas or liquid can only flow along the inside of the convergence hood 73.

[0022] like Figures 5 to 7As shown, a movable column 716 is fixedly installed between multiple movable plates 78, and the movable column 716 is vertically movably connected to the inside of multiple concave covers 77. Round rods 717 are rotatably connected on both sides of the outer surface of the movable column 716. A placement ring 718 is fitted and connected to the outer side of the round rod 717. A wave groove is opened on the top of the placement ring 718. The placement ring 718 is fixedly installed on the top of the blocking disk 72. The concave cover 77 is fixedly installed on the outside of the mounting column 71. A crossbeam is provided between the outer side of the mounting column 71 and the concave cover 77. The spacing between the nozzle 711 and the filter element 6 is one centimeter. In order to facilitate the ejected gas or liquid to impact the inner wall of the filter element 6, so that the liquid or gas flows from the inside of the filter element 6 to the outside, a rectangular rod is fixedly installed inside the positioning sleeve 76, and the movable column 716 is vertically movably connected to the outer side of the rectangular rod, which is convenient for the up and down movement of the movable column 716 without hindering the rotation of the movable column 716. When the positioning sleeve 76 rotates, the movable column 716 is driven to rotate, and when the movable column 716 rotates, the round rod 717 is driven to rotate, so that the round rod 717 moves along the wave groove inside the placement ring 718, thereby causing the movable column 716 to rise, thereby changing the difficulty of rising the movable column 716.

[0023] like Figure 6 and Figure 7 As shown, a mounting bar 713 is fixedly installed on the top of the topmost rotating circle 710, a second stirring blade 714 is fixedly installed on the top of the mounting bar 713, and a connecting column 715 is fixedly installed between two adjacent rotating circles 710; Due to the action of the guide structure 3, the gas or liquid is accelerated, and the accelerated gas or liquid drives the stirring blade 2 714 to rotate. When the stirring blade 2 714 rotates, it drives the mounting bar 713 to rotate. When the mounting bar 713 rotates, it drives the single rotating circle 710 to rotate. When the rotating circle 710 rotates, it drives the remaining rotating circles 710 to rotate through the connecting column 715, so that the multiple nozzles 711 rotate and spray inside the filter element 6, reducing blind spots.

[0024] like Fig.10 and 11 As shown, the fixing assembly 5 includes a column 51 vertically mounted on the top of the chassis 4, a barrier cover 52 is sleeved on the outer side of the column 51 at the top position of the filter element 6, a positioning screw 53 is fixedly installed at the middle of the top of the barrier cover 52, a rotating bar 54 is rotatably connected to the outer side of the positioning screw 53, a nut 55 is threadedly connected to the outer side of the positioning screw 53 at the top position of the rotating bar 54, plug rods 56 are symmetrically welded on both sides of the outer surface of the rotating bar 54, a guide groove is opened on the outer side of the top of the barrier cover 52, a round hole is opened on the top of the column 51, and the plug rod 56 runs through the inside of the round hole; The personnel install the barrier cover 52 on the top of the filter element 6 along the column 51, and then the personnel rotate the rotating bar 54. When the rotating bar 54 rotates, it drives the plug-in rod 56 to enter the round hole of the column 51. Then the personnel tighten the nut 55. The nut 55 rotates and moves along the outside of the positioning screw 53, thereby squeezing the rotating bar 54. After the rotating bar 54 is squeezed, it is fixed, so that the plug-in rod 56 is fixed. After the plug-in rod 56 is fixed, the barrier cover 52 is fixed, which changes the difficulty of fixing the barrier cover 52.

[0025] The present invention also provides a filtering method of an industrial filtering device, comprising the following steps: Step 1: Device assembly and filter element installation: Place the lower shell 1 at the designated position, install the chassis 4 at the bottom of the inner wall of the lower shell 1, and ensure that it is stable, install the reverse impact cleaning component 7 on the top of the chassis 4, and then install the filter element 6 on the top of the chassis 4 and on the outside of the reverse impact cleaning component 7, ensuring that the filter element 6 fits tightly against the chassis 4, and then install the fixing component 5 to ensure that the top of the filter element 6 is fixed.

[0026] Step 2: Start the filtering device: open the air inlet or liquid inlet of the industrial filtering device, so that the gas or liquid to be filtered enters the lower shell 1, and the fluid to be filtered is pressurized to enter the top of the filter element 6 through the action of the guide structure 3, and the liquid or gas at the bottom is evenly distributed on the outer surface of the filter element 6. Under the action of pressure or gravity, the fluid passes through the filter medium of the filter element 6 to separate the solid particles from the fluid. The filtered fluid flows from the outside to the inside of the filter element 6, and at this time flows downward through the lower shell 1 and is discharged through the air outlet or liquid outlet.

[0027] Step three: the cleaning function of the reverse impact cleaning component is started: when the gas or liquid flows, the gas or liquid drives the stirring blade 75 to rotate under the action of pressure, and the stirring blade 75 causes the movable column 716 to rotate. When the movable column 716 rotates, the round rod 717 rises or falls along the outside of the placement ring 718, and the rising or falling of the round rod 717 drives the movable column 716 to rise or fall. When the movable column 716 rises or falls, it drives the movable plate 78 to rise or fall. When the movable plate 78 rises or falls, the gas or liquid inside the concave cover 77 enters the inside of the guide plate 79, and at the same time, the gas or liquid flushes the inside of the filter element 6 along the rotating circle 710 and the nozzle 711 connected to the outside of the guide plate 79. At the same time, when the rotating circle 710 rotates, the nozzle 711 sprays the compressed gas or cleaning liquid inside the filter element 6 outward, forming a reverse rotation impact to blow off the dust or particles on the surface of the filter element 6.

[0028] Step 4: Dust collection and discharge after cleaning: The blown dust or particles are finally deposited at the bottom of the lower shell 1 and discharged to the outside of the device through a special sewage outlet.

[0029] Step 5: Maintenance and inspection of the device: Regularly check the filtration efficiency and integrity of the filter element 6 and replace the filter element 6 if necessary; Check the moving parts of the reverse impact cleaning assembly 7 to ensure that it is operating normally; Clean the chassis 4 and the bottom of the lower shell 1 of the device to prevent dust accumulation from affecting the filtering effect; Check the bolt structure and sealing parts to ensure the sealing and stability of the device.

[0030] Working principle: During the actual use of the device, the lower shell 1 is moved to a predetermined position, and then the reverse impact cleaning component 7 is installed between the chassis 4, and then the filter element 6 is installed, and then the fixing component 5 is installed. At this time, the personnel install the barrier cover 52 on the top of the filter element 6 along the column 51, and then the personnel rotate the rotating bar 54. When the rotating bar 54 rotates, it drives the plug-in rod 56 to enter the circular hole of the column 51, and then the personnel screw the nut 55. The nut 55 rotates and moves along the outside of the positioning screw 53, thereby squeezing the rotating bar 54, and the rotating bar 54 is fixed after being squeezed, so that the plug-in rod 56 is fixed, and after the plug-in rod 56 is fixed, the barrier cover 52 is fixed. This method not only improves the efficiency of installation and maintenance through modular installation and quick fixing, but also enhances the sealing, stability and reliability of the cleaning function of the device. At the same time, this design reduces the requirements for operator skills and reduces maintenance costs and downtime; Then, the air inlet of the industrial filter device is opened to allow the gas to be filtered to enter the lower shell 1. At this time, the gas is filtered through the filter element 6. Since the lower shell 1 and the upper shell 2 are continuously pressurized, the gas flows along the inside of the convergence cover 73. The flowing gas is pressurized through the convergence cover 73, and the pressurized gas is quickly discharged along the drainage pipe 74. The rapidly flowing gas after pressurization drives the stirring blade 75 to rotate. When the stirring blade 75 rotates, it can drive the positioning sleeve 76 to rotate. When the positioning sleeve 76 rotates, it drives the movable column 716 to rotate. When the movable column 716 rotates, it drives the round rod 717 to rotate, so that the round rod 717 moves along the wave groove of the placement ring 718, thereby causing the movable column 716 to rise. When the movable column 716 rises, it drives multiple movable plates 78 to rise. When the movable column 716 cannot When the movable column 716 is at the highest point between the wave trough and the ground, the movable column 716 is driven down by the gravity of the multiple movable plates 78, so that the movable column 716 drives the round rod 717 to move up and down along the outer side of the wave trough. When the movable plate 78 descends, the gas inside the concave cover 77 is squeezed, so that the gas inside the concave cover 77 enters the inside of the guide plate 79 along the pipeline at the top of the movable plate 78, and enters the inside of the rotating circle 710 along the guide plate 79, and finally sprays from the inside of the filter element 6 to the outside along the nozzle 711, which can remove impurities on the surface of the filter element 6 in real time during the filtration process, extend the service life of the filter element 6, improve the filtration efficiency and stability, and reduce the number of cleaning times. The automatic cleaning reduces manual intervention, reduces maintenance costs and time, and has good energy-saving effects and environmental protection performance. When the movable plate 78 is lifted or lowered, the nozzle 711 is lifted or lowered by the action of the guide plate 79 and the rotating circle 710, thereby increasing the spraying range. In addition, due to the action of the guide structure 3, the gas or liquid is accelerated, and the accelerated gas or liquid drives the stirring blade 2 714 to rotate. When the stirring blade 2 714 rotates, it drives the mounting bar 713 to rotate. When the mounting bar 713 rotates, it drives the single rotating circle 710 to rotate. When the rotating circle 710 rotates, it drives the remaining rotating circles 710 to rotate through the connecting column 715, thereby making the multiple rotating circles 710 rotate. The nozzles 711 rotate and spray inside the filter element 6, and at the same time drive the movable block 712 to slightly collide with the inner wall of the filter element 6. When the movable block 712 collides with the filter element 6, it drives the movable block 712 to enter the rotating circle 710. At this time, the movable block 712 is stored and moved repeatedly, so as to achieve the purpose of knocking and dust removal on the filter element 6, thereby achieving an efficient and automatic cleaning effect, reducing the cleaning blind area, reducing the maintenance cost, and having good environmental protection and energy-saving performance, and significantly improving the cleaning efficiency and reliability of the device; Finally, the filtered dust is discharged from the device along the gas outlet port at the bottom end of the chassis 4, thereby completing the overall filtration of the gas.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.

When the movable column (716) rotates, the round rod (717) rises or falls along the outer side of the placement ring (718). The rising or falling of the round rod (717) drives the movable column (716) to rise or fall. When the movable column (716) rises or falls, it drives the movable plate (78) ) rises or falls, and when the moving plate (78) rises or falls, the gas or liquid inside the concave cover (77) enters the inside of the guide plate (79), and at the same time, the gas or liquid flushes the inside of the filter element (6) along the rotating circle (710) and the nozzle (711) connected to the outside of the guide plate (79). At the same time, when the rotating circle (710) rotates, the nozzle (711) sprays the compressed gas or clean liquid inside the filter element (6) outward, forming a reverse rotation impact, and blowing off the dust or particles on the surface of the filter element (6); Step 4: dust collection and discharge after cleaning: the blown dust or particles are finally deposited at the bottom of the lower shell (1) and discharged to the outside of the device through a special sewage outlet; Step 5: Maintenance and inspection of the device: Regularly check the filtration efficiency and integrity of the filter element (6) and replace the filter element (6) if necessary; Check the moving parts of the reverse impact cleaning assembly (7) to ensure that they are functioning properly; Cleaning the bottom of the device chassis (4) and the bottom of the lower shell (1) to prevent dust accumulation from affecting the filtering effect; Check the bolt structure and sealing parts to ensure the sealing and stability of the device.
