DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 4 The present invention provides a technical solution: a dust removal and environmental protection equipment, including a collecting tube 1, a dust removal box 2 is arranged at the top of the collecting tube 1, a dust suction channel 3 and a collecting channel 10 are respectively arranged in the dust removal box 2, a rotating ring plate 6 is rotatably installed on the inner wall of the dust suction channel 3, a fan 7 is arranged in the rotating ring plate 6, and a filter screen 8 is arranged in the dust suction channel 3.

[0025] After the fan 7 starts working, it absorbs the broken iron filings and smoke in the air and puts them into the dust removal box 2. First, the iron filings and large dust particles are intercepted by the filter 8, and the small dust particles will pass through the filter 8 and continue to pass through the fan 7 into the collection tube 1.

When the threaded column 13 rotates, it drives the moving scraper 14 to move back and forth on the spray pipe 9 to clean the spray port of the spray pipe 9 to prevent dust from blocking the spray port.

[0028] See also Figure 5-Figure 8 The present invention provides a technical solution: a knocking mechanism is provided on the side of the filter screen 8, a feed pipe 5 is provided at the bottom end of the collecting channel 10, the other end of the feed pipe 5 is fixedly connected to the collecting cylinder 1, and the feed pipe 5 extends into the inner cavity of the collecting cylinder 1, a collecting mechanism is provided in the collecting channel 10, the collecting mechanism is located below the baffle 11, a connecting shaft block 35 is movably installed on the side of the baffle 11, and the baffle 11 is located above the collecting channel 10.

[0029] The knocking mechanism includes a knocking rod 21, and the knocking rod 21 is used to knock one side of the filter screen 8 to prevent iron filings and large dust particles from accumulating on the filter screen 8.

[0030] In this embodiment, an adjustment cavity is opened in the inner wall of the dust removal box 2, and a mounting frame 16 is fixedly installed in the adjustment cavity. A second rotating column 17 and a fourth rotating column 23 are movably installed inside the mounting frame 16, and the second rotating column 17 extends out of the outer side of the mounting frame 16 and is movably installed with a second transmission wheel 18. The second transmission wheel 18 is in friction contact with the rotating ring plate 6. A threaded groove is provided on the surface of the fourth rotating column 23 located inside the mounting frame 16, and a seventh driven bevel gear is fixedly installed on the end of the fourth rotating column 23. A push plate 19 is threadedly connected to the outer side of the fourth rotating column 23 through the threaded groove. The second rotating column 17 passes through the push plate 19, and a third driven bevel gear is fixedly installed on the end of the second rotating column 17.

[0031] In this embodiment, a strip-shaped limiting column 38 is fixedly installed on the surface of the second rotating column 17, and the limiting column 38 passes through the second transmission wheel 18. A connecting rod 36 is fixedly installed on the side of the pushing plate 19. The other end of the connecting rod 36 passes through the mounting frame 16 and is movably connected to the side of the second transmission wheel 18. The side of the second transmission wheel 18 is provided with an annular sliding groove 37 connected to the connecting rod 36.

[0032] In this embodiment, the knocking mechanism also includes a rotating shaft 25 and a third rotating column 20. A fourth driven bevel gear is fixedly installed on the outer side of the third rotating column 20, and the third driven bevel gear is meshingly connected with the fourth driven bevel gear. A fifth driven bevel gear is fixedly installed on the outer side of the rotating shaft 25, and the fourth driven bevel gear is meshingly connected with the fifth driven bevel gear. The knocking rod 21 is located between the filter 8 and the fan 7, and the knocking rod 21 and the collecting channel 10 are respectively located on both sides of the filter 8.

[0033] The knocking rod 21 is in the shape of a convex column, so that the knocking rod 21 can knock the filter screen 8 periodically, so that iron filings and large dust particles on the filter screen 8 can fall off the filter screen 8.

[0034] Two groups of knocking rods 21 are arranged between the filter 8 and the fan 7, and each group of knocking rods 21 is arranged at the edge of the filter 8. Firstly, the knocking rods 21 are prevented from hindering the filtering of the filter 8. At the same time, the arrangement of the two groups of knocking rods 21 can increase the uniform knocking of the filter 8 and increase the cleaning efficiency of the filter 8.

[0035] When there are a lot of iron filings and large dust particles adsorbed on the filter screen 8, the dust removal effect inside the dust removal box 2 is reduced, and the iron filings and large dust particles will accumulate on the movable plate 22. Under the action of gravity, the movable plate 22 will drive the sliding plate 28 to slide on the fixed column 27, and drive the rotating gear 26 to rotate. When the rotating gear 26 rotates, it drives the fourth rotating column 23 to rotate through the sixth driven bevel gear and the seventh bevel gear, and drives the push plate 19 to move in the installation frame 16 through the threaded groove on the fourth rotating column 23. The push plate 19 will drive the second transmission wheel 18 to move on the second rotating column 17 through the connecting rod 36 and the limiting column 38, and the connecting rod 36 is movably connected to the second transmission wheel 18 through the annular sliding groove 37, so that the second transmission wheel 18 It will contact the rotating ring plate 6 and rotate, and the second transmission wheel 18 is installed on the second rotating column 17 through the limiting column 38, so that the second rotating column 17 will rotate together, and will drive the third rotating column 20 to rotate through the third driven bevel gear and the fourth driven bevel gear. When the third rotating column 20 rotates, it will drive the rotating shaft 25 to rotate through the fourth driven bevel gear and the fifth driven bevel gear. When the rotating shaft 25 rotates, it will drive the knocking rod 21 to periodically knock the filter 8, so that the iron filings and large particles of dust on the filter 8 fall off the filter 8, preventing the flue gas dust from being blocked by the blocked filter 8, ensuring the collection of flue gas dust by the fan 7, and also protecting the fan blades of the fan 7 from being hit by iron filings and large particles of dust, thereby increasing the service life of the fan 7.

[0036] See also Figure 9-13 The present invention provides a technical solution: a collecting mechanism collects the iron filings and large dust particles dropped from the filter screen 8, and collects them into the collecting cylinder 1 through the discharge pipe 5.

[0037] In this embodiment, the collecting mechanism includes a movable plate 22, a sliding plate 28 is fixedly installed at the bottom end of the movable plate 22, an adjusting groove is opened on the side wall of the collecting channel 10, a fixed column 27 is fixedly installed on the inner wall of the adjusting groove, the fixed column 27 passes through the sliding plate 28, a compression spring 29 is fixedly installed at the bottom end of the sliding plate 28, the compression spring 29 is sleeved on the outer side of the fixed column 27, and the bottom end of the compression spring 29 is fixedly connected to the side wall of the sliding channel 10, a gear portion is provided on the side of the sliding plate 28, a fifth rotating column 24 is movably installed inside the adjusting groove, a sixth driven bevel gear and a rotating gear 26 are respectively fixedly installed on the outer side of the fifth rotating column 24, the sixth driven bevel gear is meshed with the seventh driven bevel gear, and the sliding plate 28 is meshed with the rotating gear 26 through the gear portion.

[0038] A conical collecting groove is provided on the top surface of the collecting channel 10, and the conical collecting groove is close to the side of the filter screen 8, so that the iron filings and large dust particles on the filter screen 8 can enter the collecting channel 10 through the conical collecting groove under the action of gravity.

[0039] In this embodiment, a connecting groove 30 is opened on the inner wall of the dust removal box 2. The connecting groove 30 is located around the collecting channel 10 and is not connected to the collecting channel 10. The first piston plate 31 and the second piston plate 32 are movably installed inside the connecting groove 30. The top end of the first piston plate 31 is fixedly connected to the bottom end of the sliding plate 28. The bottom end of the sliding plate 28 passes through the inner wall of the dust removal box 2 and extends into the connecting groove 30.

[0040] In this embodiment, the side of the second piston plate 32 passes through the inner wall between the connecting groove 30 and the collecting channel 10 and is fixedly installed with the pushing column 33. The top of the pushing column 33 is in active contact with the bottom end of the baffle 11. The inner wall between the connecting groove 30 and the collecting channel 10 is penetrated by a sliding hole matching the pushing column 33. A leak-proof plate 34 is fixedly installed on one side of the sliding hole at the bottom end of the second piston plate 32. The leak-proof plate 34 seals the sliding hole when the pushing column 33 rises to prevent the air pressure in the connecting groove 30 from leaking out, thereby preventing the second piston plate 32 from moving in the connecting groove 30 when the first piston plate 31 moves.

[0041] The iron filings and large dust particles collected on the movable plate 22 will cause the movable plate 22 to move downward due to their gravity, and can drive the fourth rotating column 23 to rotate through the sliding plate 28, the rotating gear 26, the sixth driven bevel gear and the seventh driven bevel gear. The second transmission wheel 18 can be brought into contact with the rotating ring plate 7 through the pushing plate 19 and the connecting rod, so as to achieve the cleaning effect of the knocking rod 21 on the filter screen 8. At the same time, during the downward movement of the sliding plate 28, the sliding plate 28 will drive the first piston plate 31 to move in the connecting groove 30, and maintain a sealed state with the connecting groove 30. When the first piston plate 31 moves in the connecting groove 30, The second piston plate 32 is squeezed toward the other end of the connecting groove 30. When the second piston plate 32 moves, the baffle 11 will rotate through the connecting shaft block 35 through the pushing column 33, so that the collecting channel 10 is exposed. The baffle 11 will be inclined with respect to the top opening of the collecting channel 10, so that the knocking rod 21 can easily collect the iron filings and large particles of dust knocked off the filter 8 into the collecting channel 10. After being knocked off, the iron filings and large particles of dust on the filter 8 enter the collecting tube 1 through the collecting channel 10, thereby ensuring the normal filtration of the filter 8. The knocking rod 21 knocking on the filter 8 can prevent the filter 8 from being blocked by iron filings or large particles of dust.

[0042] When the gravity of the iron filings and large particles of dust on the movable plate 22 becomes smaller, the squeezing force of the movable plate 22 on the compression spring 29 through the sliding plate 28 will disappear, and the sliding plate 28 will return to its original position under the elastic force of the compression spring 29, so that the first piston plate 31 will also move in the connecting groove 30, and at the same time will drive the second piston plate 32 to move together, the second piston plate 32 will slide down, and the baffle 11 will return to its original position through the connecting rod 36, and the baffle 11 will cover the collecting channel 10 again to prevent the iron filings and large particles of dust in the discharge pipe 5 from returning to the filter 8 from the discharge pipe 5 under the negative pressure of the fan 7.

[0043] The movable plate 22 moves upward or downward in the collecting channel 10 under the action of the gravity of the iron filings and large particles of dust, which causes the second transmission wheel 18 to intermittently contact the rotating ring plate 7, so that the knocking mechanism can intermittently knock the filter screen 8 to prevent the filter screen 8 from being blocked, while protecting the fan 7 from being damaged by the iron filings and large particles of dust.

[0044] See also Figure 1-Figure 13 The present invention provides a technical solution: a dust removal method for dust removal and environmental protection equipment, comprising the following steps: Step 1: Start the motor 4, and drive the fan 7 to work through the first transmission wheel 12 and the rotating ring plate 6 to collect iron filings and large dust particles. The filter 8 intercepts the iron filings and large dust particles, while the small dust particles pass through the filter 8 and are collected in the collection tube 1 under the action of the water flow of the spray pipe 9. The spray will increase the weight of the dust in the dust removal box 2, so that the dust in the dust removal box 2 can be quickly collected in the collection tube 1; Step 2: The iron filings and large dust particles at the filter screen 8 are collected through the collecting channel 10 and the feeding pipe 5. When the filter screen 8 is blocked, the movable plate 22 moves downward and is meshed and connected with the rotating ring plate 6 through the second transmission wheel 18, and the second rotating column 17 and the third rotating column 20 drive the knocking rod 21 in the knocking mechanism to knock the iron filings and large dust particles remaining in the filter screen 8, so that the iron filings and large dust particles are knocked off the filter screen 8 and fall at the bottom end of the side of the filter screen 8, and then enter the collecting channel 10 and the feeding pipe 5 into the collecting cylinder 1; Step three: Iron filings and large particles of dust will fall into the conical collecting trough through the conical collecting trough and be collected on the movable plate 22. The movable plate 22 will move downward due to the gravity of the iron filings and large particles of dust. When the movable plate 22 moves downward, the first piston plate 31, the second piston plate 32, the connecting groove 30 and the push column 33 will cooperate to make the baffle 11 rotate, and be inclined to the top surface of the collecting channel 10, so that the iron filings and large particles of dust can enter the collecting channel 10. After the iron filings and large particles of dust on the side of the filter 8 enter the collecting channel 10, the protective plate 11 will return to its original position to block the collecting channel 10 to prevent the iron filings and large particles of dust in the discharge pipe 5 from returning to the filter 8 under negative pressure.
