[0002] In the process of cement production, solid cement materials need to go through the steps of crushing and mixing, and a large amount of dust will be generated during the processing, which will seriously affect the air quality of the surrounding environment and the physical and mental health of the workers. Therefore, relevant dust removal equipment is needed to remove the dust generated in the cement production process.

[0003] When existing dust removal equipment is used to remove dust generated in the cement production process, most of them allow the dust-laden air to pass through the built-in filter of the dust removal equipment, and use the filter to filter and intercept the dust in the air. However, as the dust removal continues, more and more dust is intercepted on one side of the filter, and the filter is prone to clogging. Therefore, the filter needs to be cleaned regularly. In the prior art, the filter is mostly cleaned manually, and the efficiency of manual cleaning of the filter is relatively low. In addition, the dust removal equipment needs to be stopped during the cleaning process of the filter, which will affect the subsequent filtration of the dust-laden flue gas and make the filtration efficiency of the dust-laden flue gas relatively low.

DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

The connection plate 10 is hollow inside, the air intake pipe 20 is arranged at one side edge of the connection plate 10 and communicates with the inner cavity of the connection plate 10, the exhaust pipe 30 is arranged at the other side edge of the connection plate 10 and communicates with the inner cavity of the connection plate 10, the air intake pipe 20 and the exhaust pipe 30 are arranged opposite to each other, the filter screen 60 is provided with a plurality of groups, and a plurality of the filter screens 60 are arranged at The interior of the connecting plate 10 is distributed in a ring-shaped interval. The first driving assembly 40 is installed on one side of the connecting plate 10, and is used to drive a plurality of the filter screens 60 to rotate intermittently. The second driving assembly 70 and the piston assembly 80 are installed on the other side of the connecting plate 10. When a group of the filter screens 60 are removed from between the intake pipe 20 and the exhaust pipe 30, the second driving assembly 70 is used to drive the piston assembly 80 to move. When the piston assembly 80 moves, air is pressed into the interior of the connecting plate 10 to blow away the dust intercepted on the group of the filter screens 60.

[0017] Initially, a group of filters 60 is located between the air intake pipe 20 and the exhaust pipe 30. When it is necessary to remove dust generated during cement production, an external pump group (not shown in the figure) can be used to pump dust-containing air from the air intake pipe 20 to the inside of the adapter plate 10, and then discharged from the exhaust pipe 30. At this time, the dust-containing air can pass through the filter 60 located between the air intake pipe 20 and the exhaust pipe 30, and the group of filters 60 is used to filter and intercept dust in the air to achieve the purpose of dust removal. In the above process, the first drive assembly 40 drives the plurality of filters 60 to rotate intermittently, so as to adjust the plurality of filters 60 to the position between the air intake pipe 20 and the exhaust pipe 30 in sequence. , so that several filters 60 can participate in the filtering and interception of air dust, and when a group of filters 60 is removed from between the intake pipe 20 and the exhaust pipe 30, the second driving assembly 70 drives the piston assembly 80 to move, and the piston assembly 80 presses air into the inside of the connecting plate 10 when it moves. After the air flow enters the inside of the connecting plate 10, it passes through the filter 60 removed from between the intake pipe 20 and the exhaust pipe 30 in the reverse direction, and then blows away the dust intercepted on the filter 60, thereby realizing automatic cleaning of the filter 60, avoiding clogging of the filter 60 caused by excessive dust on the filter 60, and ensuring that the filter 60 can continuously and efficiently filter the dust-containing air.

[0018] See also Figure 1 In one embodiment, the first driving assembly 40 includes a rotating shaft 401, a motor 402, an incomplete gear 403, a gear 404 and a rotating disk 405, the rotating shaft 401 passes through the connecting disk 10 along the axial direction of the connecting disk 10, the rotating disk 405 is arranged inside the connecting disk 10, the rotating disk 405 is fixedly connected to the rotating shaft 401, the motor 402 is fixedly installed on one side of the connecting disk 10, the incomplete gear 403 is installed at the output end of the motor 402, the gear 404 is fixedly arranged at one end of the rotating shaft 401 and can intermittently mesh with the incomplete gear 403, the rotating disk 405 is provided with a plurality of through openings distributed in an annular manner at an eccentric position, a plurality of the filter screens 60 are installed in a one-to-one correspondence inside the plurality of through openings, and protective columns 101 are fixedly arranged at the center positions on both sides of the connecting disk 10, and the protective columns 101 are sleeved on the outside of the rotating shaft 401.

[0019] The incomplete gear 403 is driven to rotate by the motor 402. When the incomplete gear 403 is out of mesh with the gear 404, the turntable 405 remains stationary inside the adapter plate 10, so that a group of filters 60 is located between the intake pipe 20 and the exhaust pipe 30 to filter the dust-containing air flowing through the inside of the adapter plate 10. When the incomplete gear 403 is in mesh with the gear 404, the incomplete gear 403 drives the gear 404 to rotate a certain angle, thereby driving the rotating shaft 401 and the turntable 405 to rotate a certain angle. When the turntable 405 rotates a certain angle, it drives several filters 60 to rotate a certain angle, so that the filter 60 located between the intake pipe 20 and the exhaust pipe 30 is rotated away from the current position, and at the same time, the next group of filters 60 is rotated to between the intake pipe 20 and the exhaust pipe 30 to continue filtering the subsequent dust-containing air.

[0020] See also Figure 1 , Figure 2 , Figure 4 as well as Figure 5 In one embodiment, the piston assembly 80 includes a piston rod 802, an air cylinder 803, a piston block 805 and an elastic member 806. The air cylinder 803 is fixedly arranged on one side edge of the connecting plate 10 and communicates with the inner cavity of the connecting plate 10. The piston block 805 is movably arranged inside the air cylinder 803. One end of the piston rod 802 is fixedly connected to the piston block 805, and the other end extends to the outside of the air cylinder 803. One end of the elastic member 806 is connected to the inner wall of the air cylinder 803, and the other end is connected to the piston block 805, which is used to provide elastic support for the piston block 805. The piston rod 802 is located in the air cylinder 80 A connecting rod 801 is fixedly arranged at one end of the outer portion of the second driving assembly 70, the second driving assembly 70 comprises a roller 701, a spiral plate 702 and a strip plate 703, the roller 701 is fixedly arranged at one end of the rotating shaft 401 away from the gear 404, the spiral plates 702 are provided in a plurality of groups, the plurality of spiral plates 702 are distributed in an annular manner and fixedly arranged on the circumferential side wall of the roller 701, two adjacent groups of the spiral plates 702 are connected by the strip plate 703, the strip plate 703 is arranged along the axial direction of the roller 701, the end of the connecting rod 801 away from the piston rod 802 extends to the inner side of the spiral plate 702 and is in contact with the spiral plate 702.

[0021] When the motor 402 drives the incomplete gear 403 to rotate and then drives the shaft 401 and the turntable 405 to rotate intermittently, the shaft 401 can also drive the roller 701 and the plurality of spiral plates 702 on the circumferential side wall of the roller 701 to rotate intermittently. When a group of filters 60 located between the intake pipe 20 and the exhaust pipe 30 rotates away from the current position, a group of spiral plates 702 on the circumferential side wall of the roller 701 acts on the connecting rod 801. The connecting rod 801 is pushed by the spiral plates 702 and then drives the piston rod 802 to move outside the air storage cylinder 803, thereby pulling the piston block 805 so that the piston block 805 moves along the inside of the air storage cylinder 803, thereby completing the air extraction action. When the elastic member 806 is compressed, the connecting rod 801 slides along the side wall of the current spiral plate 702; when a group of filters 60 located between the intake pipe 20 and the exhaust pipe 30 rotates away from the current position, the group of filters 60 can be rotated to the outlet end of the air storage cylinder 803, and the connecting rod 801 slides away from one end of the current spiral plate 702. At this time, the elastic member 806 pushes the piston block 805 to make the piston block 805 move in the opposite direction along the inside of the air storage cylinder 803, and then the air inside the air storage cylinder 803 is compressed and sent to the inside of the connecting plate 10. After entering the inside of the connecting plate 10, the air can pass through the group of filters 60 in the opposite direction to blow away the dust intercepted on one side of the group of filters 60, thereby realizing the automatic cleaning of the group of filters 60.

[0022] See also Figure 4 as well as Figure 5 In one embodiment, a guide strip 807 is fixedly provided on the inner wall of the gas storage cylinder 803 along the axial direction, and a groove (not shown in the figure) adapted to the guide strip 807 is opened on the circumferential side wall of the piston block 805.

[0023] The circumferential side wall of the piston block 805 is slidably matched with the guide strip 807 through the groove, so that the spiral plate 702 can smoothly push the connecting rod 801 when rotating, and then drive the piston block 805 to move smoothly along the inside of the air storage cylinder 803 through the piston rod 802, so as to smoothly pump air.

[0024] See also Figure 1 as well as Figure 2 In one embodiment, a collecting assembly 50 is further provided on the side of the connecting plate 10 away from the air storage cylinder 803. After the air passes through the filter 60 in reverse to blow the dust off the filter 60, the collecting assembly 50 is used to collect the blown dust.

[0025] See also Figure 1 , Figure 3 as well as Figure 4In one embodiment, the collecting assembly 50 includes a collecting pipe 501 and a collecting box 502. The collecting pipe 501 is fixedly arranged on the side wall of the connecting plate 10 and is connected to the inner cavity of the connecting plate 10. The end of the collecting pipe 501 away from the connecting plate 10 is connected to the collecting box 502. The collecting pipe 501 and the air storage cylinder 803 are arranged opposite to each other. The end of the collecting box 502 away from the collecting pipe 501 is provided with an exhaust port, and a partition net 503 is installed in the exhaust port.

[0026] After the piston block 805 moves in the opposite direction along the inside of the air cylinder 803 to pressurize the air inside the air cylinder 803 to the inside of the connecting plate 10, the air flows in the opposite direction through the filter 60 to blow away the dust intercepted on the filter 60. After the dust is blown away, it enters the collection tube 501 together with the air flow, and then enters the collection box 502 from the collection tube 501. Finally, the air flows through the partition 503 and is discharged to the outside, while the dust is intercepted by the partition 503 inside the collection box 502, thereby realizing dust collection.

[0027] See also Figure 2 , Figure 3 , Figure 4 as well as Figure 5 In one embodiment, a gas supply pipe 804 is disposed on the side wall of the gas storage cylinder 803, and a one-way valve (not shown in the figure) is disposed inside the gas supply pipe 804 and the collecting pipe 501.

[0028] When the spiral plate 702 pushes the connecting rod 801 and then drives the piston block 805 to move along the inside of the air cylinder 803, the one-way valve inside the air supply pipe 804 is in an open state, and the one-way valve inside the collecting pipe 501 is in a closed state. The outside air responds to the movement of the piston block 805 and enters the air cylinder 803 through the air supply pipe 804. When the connecting rod 801 slides away from one end of the spiral plate 702 and the elastic member 806 pushes the piston block 805 to move in the opposite direction along the inside of the air cylinder 803, the one-way valve inside the air supply pipe 804 is in a closed state, and the one-way valve inside the collecting pipe 501 is in an open state, so that the air inside the air cylinder 803 can be smoothly pressed and sent to the inside of the connecting plate 10, so as to smoothly backwash and clean the filter 60.

[0029] In one embodiment, the elastic member 806 may be a spring or a metal spring, which is not limited here.

[0030] In the embodiment of the present invention, initially, a group of filters 60 is located between the air intake pipe 20 and the exhaust pipe 30. When it is necessary to remove dust generated in the cement production process, an external pump group (not shown in the figure) can be used to pump the dust-containing air from the air intake pipe 20 to the inside of the connecting plate 10, and then discharged from the exhaust pipe 30. At this time, the dust-containing air can pass through the filter screen 60 located between the air intake pipe 20 and the exhaust pipe 30, and the group of filters 60 can be used to filter and intercept dust in the air to achieve the purpose of dust removal; in the above process, the first drive component 40 drives the plurality of filters 60 to rotate intermittently, so as to adjust the plurality of filters 60 to between the air intake pipe 20 and the exhaust pipe 30 in turn, so that the plurality of filters 60 can participate in the filtering and interception of air dust, and when a group of filters 60 is moved from the air intake pipe 20 to the exhaust pipe 30, the plurality of filters 60 can be moved from the air intake pipe 20 to the exhaust pipe 30. After the air pipe 30 is removed, the piston assembly 80 is driven to move by the second drive assembly 70. When the piston assembly 80 moves, air is pressed into the connecting plate 10. After the air flow enters the connecting plate 10, it passes through the filter 60 removed from between the intake pipe 20 and the exhaust pipe 30 in the reverse direction, and then the dust intercepted on the filter 60 is blown away, thereby realizing automatic cleaning of the filter 60, avoiding clogging of the filter 60 due to excessive dust on the filter 60, and ensuring that the filter 60 can continuously and efficiently filter the dust-containing air. Compared with the prior art, when removing the dust generated in the cement production process, the filter 60 used to filter the dust-containing air can be automatically cleaned online, thereby avoiding clogging of the filter 60 due to excessive dust on one side of the filter 60, and improving the filtering efficiency of the dust-containing air.
