Description

Technical Field

[0001] This application relates to the field of flue gas dust removal, and specifically relates to a dust collector whose usage state can be automatically adjusted and switched internally. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The quality of a dust collector is closely related to the amount of gas that can be processed, the resistance loss, and the dust removal efficiency, etc. On the other hand, whether the maintenance of the dust collector is complicated and whether the maintenance period is too short will also affect the quality of the dust collector. There are many types of dust collectors. Among them, the dust collector based on dust removal filter bags is one of the most widely used dust collectors. Its dust removal principle is mainly that the air flow enters from the inlet pipe. When the air flow passes through the dust removal filter bag, the surface of the filter bag has the function of filtering dust, so that the air flow coming out of the outlet pipe is the dust-removed air flow. The principle and structure are very simple, and the replacement and maintenance of the dust removal filter bag are relatively convenient, so it is widely used. On the other hand, its dust removal efficiency is mainly based on the quality of the dust removal filter bag. Therefore, how to achieve efficient filtration of the dust removal filter bag has become the key to improvement. For this purpose, on the one hand, the dust removal efficiency of the dust removal filter bag itself can be improved. On the other hand, in actual use, generally, the dust removal filter bags are distributed in an array, and there is usually one inlet pipe and one outlet pipe respectively. Therefore, in fact, the intensity and flux of the air flow experienced by each dust removal filter bag are different. Although there are air guiding devices such as an air inlet hood, an air outlet hood, and even a wind guiding plate, relatively speaking, the dust removal filter bags closer to the inlet pipe still bear more filtering tasks. Therefore, these dust removal filter bags adsorb more dust. On the contrary, the dust removal filter bags farther from the inlet pipe adsorb less dust. Therefore, the following situation will occur. When replacing the filter bags for maintenance, some filter bags must be replaced due to dust pollution, while some filter bags can still be used. Therefore, the replacement cycles of the filter bags in different positions are different, which brings difficulties to the maintenance operation of the dust collector. Summary of the Invention

[0003] Object of the Invention: In order to overcome the defects mentioned in the above prior art, this application discloses a dust collector whose usage state can be automatically adjusted and switched internally.

[0004] Technical Solution: A dust collector includes a dust removal part, an air inlet part, and an air outlet part. The air inlet part includes an inlet pipe and an air inlet hood connected to the inlet pipe. The air outlet part includes an outlet pipe and an air outlet hood connected to the outlet pipe. The dust removal part includes a cylindrical outer shell connected to both the air inlet hood and the air outlet hood, and a plurality of dust removal filter bags located inside the outer shell.

[0005] Furthermore, a circular mounting plate is fixed inside the housing. There are multiple dust removal mounting positions at the circular mounting plate. Each dust removal mounting position has 3 ventilation holes distributed in an equilateral triangle, including 1 inner ventilation hole and 2 outer ventilation holes. A functional unit is installed at each dust removal mounting position. The functional unit includes a rotating shaft, a central rotating plate fixedly connected to the rotating shaft, and 3 dust removal filter bags. A radial connecting plate is connected between each dust removal filter bag and the central rotating plate. The dust removal filter bag includes a cage and a filter bag body. The top end of the cage abuts against the lower surface of the circular mounting plate. A bottom fixing frame is fixed inside the housing. The top end of each rotating shaft passes through the circular mounting plate, and the bottom end passes through the bottom fixing frame. Each rotating shaft is connected to the circular mounting plate through an upper bearing, and each rotating shaft is connected to the bottom fixing frame through a lower bearing.

[0006] Furthermore, the bottom fixing frame includes a central circular plate, an inner circular ring plate, an outer circular ring plate, multiple first connecting plates connecting the central circular plate and the inner circular ring plate, and multiple second connecting plates connecting the inner circular ring plate and the outer circular ring plate. The outer circular ring plate is fixedly connected to the housing, and all the lower bearings are installed at the inner circular ring plate.

[0007] Furthermore, the cage includes a top circular ring, multiple support circular rings, and multiple support vertical rods. The multiple support vertical rods are distributed at equal intervals in a ring shape, and each support vertical rod is fixedly connected to the top circular ring and all the support circular rings.

[0008] Furthermore, the top circular ring abuts against the lower surface of the circular mounting plate, and the top circular ring has a circular groove.

[0009] Thus, the circular groove can be used to fixedly install the top end of the filter bag body.

[0010] Further, a column is fixed at the center circular plate. A motor box is connected between the top end of the column and the lower surface of the circular mounting plate. A driving motor is installed inside the motor box. A driving plate is installed inside the housing above the circular mounting plate. The driving plate includes a movable plate, an inner sliding plate connected to the movable plate, and an outer sliding plate connected to the inner sliding plate through an inverted U-shaped frame. The motor shaft of the driving motor passes through the circular mounting plate and is connected to the movable plate to drive the movable plate to rotate. The outer sliding plate has an inner arc edge, and a driving tooth unit is provided at the inner arc edge. The driving tooth unit includes a plurality of tooth teeth distributed at equal intervals in an arc shape. A passive gear is fixed at the rotating shaft. When the driving tooth unit passes by the passive gear, the rotating shaft corresponding to the passive gear rotates 120 degrees. The driving plate can be in a standby state. In the standby state, the driving plate is located at one of the dust removal installation positions, and the first through hole faces the first ventilation hole of this dust removal installation position. The two second through holes respectively face the two second ventilation holes of this dust removal installation position, and the driving tooth unit is not engaged with the passive gear of this dust removal unit.

[0011] Further, a plurality of pressing units are installed on the upper surface of the circular mounting plate. The number of the pressing units is equal to that of the rotating shafts and they correspond to each other one by one. The pressing unit includes a fixed block, an arc-shaped panel connected to the fixed block, and a U-shaped pressing plate connected to the arc-shaped panel and capable of pressing the passive gear.

[0012] The pressing unit can press the passive gear. Thus, under the action of the pressing unit, the rotating shaft will not rotate accidentally under the action of the dust removal air flow, but can rotate under the strong driving of the driving tooth unit.

[0013] Further, in the standby state, the axis of the first through hole is collinear with the axis of the first ventilation hole, and the axis of each second through hole is collinear with the axis of the corresponding second ventilation hole.

[0014] Further, the diameters of the first through hole, the second through hole, the first ventilation hole, and the second ventilation hole are equal.

[0015] Thus, the first through hole can be used corresponding to the first ventilation hole, and the second through hole can be used corresponding to the second ventilation hole.

[0016] Further, the inner sliding plate has a first through hole, and the outer sliding plate has two second through holes; an inner shielding unit is installed at the inner sliding plate, and two outer shielding units are installed at the outer sliding plate; the inner shielding unit includes a first rotary cylinder, a first rotary plate driven by the first rotary cylinder, a first arc-shaped panel connected to the first rotary plate, and a first cover plate connected to the first arc-shaped panel and capable of closing the first through hole; the outer shielding unit includes a second rotary cylinder, a second rotary plate driven by the second rotary cylinder, a second arc-shaped panel connected to the second rotary plate, and a second cover plate connected to the second arc-shaped panel and capable of closing the second through hole.

[0017] Further, a cylindrical block is fixed to the top end of the rotating shaft, and a triangular pyramid-shaped slot is provided at the cylindrical block; a plurality of vertical sliding rails are fixed to the inner side wall of the housing, and a locking unit is installed in the housing. The locking unit includes a lifting ring and a plurality of mounting brackets fixedly connected to the lifting ring. The mounting bracket includes a first horizontal rod fixedly connected to the lifting ring, an arc-shaped rod connected to the first horizontal rod, a second horizontal rod connected to the arc-shaped rod, and a vertical rod fixedly connected to the second horizontal rod. A plug block matching the slot is fixed to the bottom end of the vertical rod. The lifting ring has a sliding rail groove matching the vertical sliding rail, and electric lifting rods are connected between at least two mounting brackets and the circular mounting plate.

[0018] The arc-shaped rod at the mounting bracket makes the mounting bracket have a certain elasticity, so that the plug block can more easily press against the slot to lock the position of the cylindrical block, making the position of the rotating shaft more stable.

[0019] Further, a wireless communication unit is further included. The first rotary plate is connected to a detection substrate. A light source part and an image acquisition part are installed on the lower surface of the detection substrate. The first cover plate is made of a transparent material; a plurality of connection grooves are provided on the upper surface of the circular mounting plate. The number of the connection grooves is equal to that of the first ventilation holes and they correspond to each other one by one. Each first ventilation hole is connected to a connection groove; the first rotary cylinder and the two second rotary cylinders can be in a closed state and an open state. When the first rotary cylinder and the two second rotary cylinders are in the closed state, the first cover plate closes the first through hole, and each second cover plate closes the corresponding second through hole; when the first rotary cylinder and the two second rotary cylinders are in the open state, the first cover plate does not close the first through hole, and each second through hole is not closed by the corresponding second cover plate, and the first cover plate is located above one of the connection grooves.

[0020] Further, a diversion inclined surface is provided at the connection groove.

[0021] Thus, a part of the filtered air flow can impact the first cover plate along the diversion inclined surface.

[0022] Further, both the first cover plate and the second cover plate are circular.

[0023] Further, both the first arc panel and the second arc panel are semi-cylindrical.

[0024] Further, the upper surface of the circular mounting plate has an annular chute, and the inner sliding plate is provided with an arc-shaped slider that cooperates with the annular chute; the inner sliding plate has an outer arc edge, and the inner side of the outer sliding plate has an inner arc edge and the outer side has an outer arc edge; there are two inverted U-shaped frames.

[0025] Thus, the connection of the two inverted U-shaped frames is more stable, and the design of the inverted U-shaped frame is used to avoid the cylindrical block.

[0026] Further, a plurality of dust removal mounting positions are distributed at equal intervals in a ring shape; the number of both the dust removal mounting positions and the mounting brackets is 6.

[0027] Further, the housing is also provided with a maintenance port, and a maintenance door is provided at the maintenance port.

[0028] Further, a dust cleaning unit can also be installed inside the housing.

[0029] Further, a dust feeding pipe is also connected to the air inlet pipe.

[0030] Further, fixed flanges are fixed to the top of the air inlet hood, the bottom of the air outlet hood, the top and the bottom of the housing, and both the air inlet pipe and the air outlet pipe are L-shaped pipes.

[0031] Further, the plug block includes a triangular cylindrical part and a triangular conical part connected to the triangular cylindrical part.

[0032] Further, there are 2 - 6 electric lifting rods.

[0033] Beneficial effects: The dust collector of the present application adopts a method of taking three dust removal filter bags as a group. Thus, during specific use, a group formed by three dust removal filter bags can rotate, so that one of the dust removal filter bags can be rotated to a position close to the air inlet pipe alternately, thereby alternately using the dust removal filter bags to undertake the heaviest dust removal task. Thus, after a cycle of use, the degrees of use of the three dust removal filter bags in the same group are close, so that they can be replaced together when replacing the dust removal filter bags.

[0034] On the other hand, when the three - in - one dust removal filter bags perform state switching, the dust collector does not need to be shut down, and the state can be switched during the dust removal process.

[0035] In addition, the dust collector of the present application can achieve the monitoring function of the dust removal effect, and the monitoring information can be remotely transmitted to help the control room monitor the dust removal work. Description of the Drawings

The driving plate can be in a standby state. In the standby state, the driving plate is located at one of the dust removal installation positions, and the first through hole 7.2.1 faces the first ventilation hole 3.2.1 of this dust removal installation position.

The lifting ring 6.1 has a slide rail chute matching the vertical sliding rail 3.4, and electric lifting rods 6.4 are connected between at least two mounting brackets 6.2 and the circular mounting plate 3.1.In addition, in order to monitor the dust removal effect, it further includes a wireless communication unit. The first rotating plate 7.2.3 is connected to a detection substrate. A light source part and an image acquisition part 7.2.7 are installed on the lower surface of the detection substrate 7.2.6. The first cover plate 7.2.5 is made of a transparent material. The upper surface of the circular mounting plate 3.1 has a plurality of connecting grooves 3.7. The number of the connecting grooves 3.7 is equal to that of the first ventilation holes 3.2.1 and they correspond to each other one by one. Each first ventilation hole 3.2.1 is connected to a connecting groove 3.7. The first rotating cylinder 7.2.2 and the two second rotating cylinders 7.4.2 can be in a closed state and an open state. When the first rotating cylinder 7.2.2 and the two second rotating cylinders 7.4.2 are in the closed state, the first cover plate 7.2.5 closes the first through hole 7.2.1, and each second cover plate 7.4.5 closes the corresponding second through hole 7.4.1. When the first rotating cylinder 7.2.2 and the two second rotating cylinders 7.4.2 are in the open state, the first cover plate 7.2.5 does not close the first through hole 7.2.1, and each second through hole 7.4.5 does not close the corresponding second through hole 7.4.1, and the first cover plate 7.2.5 is located above one of the connecting grooves 3.7.

[0053] The connecting groove 3.7 has a diversion inclined surface. Both the first cover plate 7.2.5 and the second cover plate 7.4.5 are circular. Both the first arc-shaped plate 7.2.4 and the second arc-shaped plate 7.4.4 are semi-cylindrical rings. The upper surface of the circular mounting plate 3.1 has an annular sliding groove 3.3. The inner sliding plate 7.2 has an arc-shaped slider that cooperates with the annular sliding groove 3.3. The inner sliding plate 7.2 has an outer arc-shaped edge. The inner side of the outer sliding plate 7.4 has an inner arc-shaped edge and the outer side has an outer arc-shaped edge. There are two inverted U-shaped frames 7.3. A plurality of dust removal installation positions are distributed at equal intervals in a ring shape. The number of both the dust removal installation positions and the mounting frames 6.2 is 6. Fixed flanges are fixed at the top of the air inlet hood 1.1, the bottom of the air outlet hood 2.1, the top and the bottom of the housing. Both the air inlet pipe 1.2 and the air outlet pipe 2.2 are L-shaped pipes.

[0054] As shown in the figure, for the dust collector of the present application, air enters from the lower intake pipe, and after passing through the dust removal filter bag, it exits from the upper outlet pipe. As described in the figure, the internal dust removal filter bags are circularly divided into an inner ring and an outer ring. Therefore, the dust removal filter bags in the inner ring are closer to the intake pipe, so they are more polluted and have a shorter replacement cycle. The dust removal filter bags in the outer ring are farther from the intake pipe, so they are less polluted and have a longer replacement cycle. However, the innovation of the present application lies in that three dust removal filter bags are grouped together and connected to the rotating shaft. Thus, through the rotation of the rotating shaft, the three filter bags can be respectively in the position of the inner ring, so that the three filter bags are dusted in both the inner ring position and the outer ring position within one replacement cycle, making the replacement cycles of the three dust removal filter bags consistent, which is more convenient for the maintenance of the dust collector.

[0055] Specifically, each time the position of the dust removal filter bag is adjusted, as Figure 9 shown, the locking unit is first unlocked as described above, and the first and second cover plates rotate to close the first and second through holes. Thus, when the driving plate rotates, the first ventilation hole and the two second ventilation holes of the functional unit in the adjusted state will be in a closed state, preventing unfiltered flue gas from rising above the circular mounting plate. Next, as Figure 10 shown, the driving motor drives the driving plate to rotate. Thus, during the rotation of the driving plate, the driving tooth unit will engage with the passive gear, and when the driving tooth unit disengages from the passive gear, the rotating shaft just rotates 120 degrees (just rotating one of the dust removal filter bags in the outer ring to the inner ring position and rotating the original dust removal filter bag in the inner ring to the outer ring position). Next, as Figure 11 shown, the driving plate moves to the next dust removal installation position, and the first and second cover plates open, enabling the dust removal filter bag at this dust removal installation position to be used for dust removal. Next, as Figure 12 shown, the locking unit descends and locks, so that the plug matches the slot, thereby locking and fixing the position of the rotating shaft. The function of the plug is, on the one hand, to lock the cylindrical block, and on the other hand, since the plug is triangular pyramid-shaped, even if there is a certain error in the driving of the passive gear by the driving tooth unit, this error can be corrected by the plug after the plug is inserted into the slot.

[0056] In addition, during normal dust removal, part of the dust-removed airflow will impact the first cover plate under the action of the guiding inclined plane. Since the first cover plate is transparent, the dust removal effect of the airflow can be monitored by collecting the image of the first cover plate. Moreover, the adjustment of the states of the functional units at each dust removal installation position can be carried out at intervals. For example, after the state of the functional unit at one dust removal installation position is adjusted, the dust collector is allowed to operate for a period of time, and then the state of the functional unit at the next dust removal installation position is adjusted. As a result, the detection substrate can stay at the detection installation position opposite to the detection installation position where the drive board is located for a relatively long time, so that each detection installation position can be monitored.

[0057] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
