In one embodiment, referring to fig. 1 to 3, a cathode frame 100 includes a cathode suspension beam 110, a cathode wire 120, a first connecting member 130, and a pushing member 140. The cathode lines 120 are suspended from the cathode hanger beam 110, and a plurality of cathode lines 120 are arranged at intervals along the length direction of the cathode hanger beam 110. The longitudinal direction is a direction in which the longest side of the cathode suspension beam 110 is located. One end of the first connector 130 is movably connected to the cathode hanging beam 110, and the other end of the first connector 130 is connected to the cathode line 120. The pushing member 140 abuts or is connected to the cathode line 120 for pushing the cathode line 120 to move.
The conventional wet electrostatic precipitator cathode frame 100 includes cathode hanger beams 110 and cathode wires 120. Pressure-bearing insulators 200 are arranged at two ends of the electric dust collector shell 300, and the cathode hanging beam 110 is transversely arranged on the two pressure-bearing insulators 200. The upper ends of a plurality of cathode wires 120 are hung on the cathode hanging beam 110 at regular intervals, a piece of anode plate 150 is arranged between every two adjacent cathode wires 120, the lower ends of the cathode wires 120 are connected with the anti-swing rod, the two ends of the anti-swing rod are connected with the shell 300 of the electric dust collector through the connecting plate processed with the long-hole groove, the long-hole groove is vertically downward, the two ends of the anti-swing rod can slide in the long-hole groove, and the position of the cathode wires 120 can be adjusted. However, the anti-swing rod is arranged in the wet electric dust collector, so that the wet electric dust collector is higher in height, and the cost is increased. In addition, after the anti-swing rod is used, the creepage phenomenon is easily generated in the wet electric dust collector, so that the normal operation of the wet electric dust collector is influenced.
However, the cathode frame 100 of the present embodiment connects the cathode line 120 to the cathode hanger beam 110 by providing the first connection member 130. The cathode line 120 is connected to the first connecting member 130 and the pushing member 140, respectively. When the pushing member 140 is moved, since the first connecting member 130 can move relative to the cathode hanging beam 110, the pushing member 140 drives the cathode wire 120 to drive the first connecting member 130 to move relative to the cathode hanging beam 110, and finally the cathode wire 120 moves relative to the cathode hanging beam 110, so as to adjust the distance from the cathode wire 120 to the anode plate 150, which is beneficial to adjusting the dust removal efficiency of the electric dust remover at any time. This negative pole frame 100 simple structure need not use and prevents the pendulum rod, is favorable to reducing electrostatic precipitator's height, and reduce cost effectively reduces the production of creepage phenomenon simultaneously, is favorable to improving electrostatic precipitator's life.
In one embodiment, referring to fig. 1 to 3, the cathode hanging beam 110 is provided with a first mounting hole 111 along the length direction thereof, one end of the first connecting element 130 is inserted into the first mounting hole 111, and the first connecting element 130 is movable in the first mounting hole 111 along the length direction of the cathode hanging beam 110. Specifically, the first mounting hole 111 may be a kidney-shaped hole, the first connecting member 130 may be a rod member, and an end cap is disposed at the top of the rod member. After the rod piece is arranged in the waist-shaped hole in a penetrating mode, the end cover of the rod piece cannot pass through the waist-shaped hole due to the fact that the end cover is large in size, and therefore the rod piece can move in the waist-shaped hole along the length direction of the waist-shaped hole. The end of the rod far from the end cap is connected with the end of the cathode wire 120 by screwing, welding, etc., and is not limited in this respect. Thus, when the pushing member 140 drives the cathode wire 120 to move, the cathode wire 120 drives the rod member to move in the kidney-shaped hole, and finally the cathode wire 120 moves relative to the cathode hanging beam 110, so that the distance from the cathode wire 120 to the anode plate 150 can be adjusted, which is beneficial to conveniently and rapidly adjusting the dust removal efficiency of the electric dust collector.
As another alternative, referring to fig. 1 and 4, the cathode frame 100 further includes a second connecting member 160. The second connecting member 160 is fixed to the cathode hanging beam 110, the second connecting member 160 is provided with a second mounting hole 161, one end of the first connecting member 130 is inserted into the second mounting hole 161, and the first connecting member 130 can move in the second mounting hole 161 along the length direction of the cathode hanging beam 110. Specifically, the second connection member 160 may be an angle steel connection member, one end of which is connected to the cathode hanging beam 110, and the other end of which is provided with a second mounting hole 161. The angle iron connector includes a first folded surface 162 and a second folded surface 163, and the first folded surface 162 is fixed to the cathode suspension beam 110 by welding, screwing, or the like. The second folded surface 163 is parallel to the surface of the cathode hanging beam 110 facing the cathode line 120, and the second folded surface 163 is provided with a second mounting hole 161. The second mounting hole 161 is a kidney-shaped hole formed along the length direction of the cathode hanging beam 110, and the first connecting member 130 may still be a rod member having an end cap at the top thereof. After the rod piece is arranged in the waist-shaped hole in a penetrating mode, the end cover of the rod piece cannot pass through the waist-shaped hole due to the fact that the end cover is large in size, and therefore the rod piece can move in the waist-shaped hole along the length direction of the waist-shaped hole. The end of the rod far from the end cap is connected with the end of the cathode wire 120 by screwing, welding, etc., and is not limited in this respect. Thus, when the pushing member 140 drives the cathode wire 120 to move, the cathode wire 120 drives the first connecting member 130 to move in the second mounting hole 161, and finally the cathode wire 120 moves relative to the cathode hanging beam 110, so that the distance from the cathode wire 120 to the anode plate 150 can be adjusted, which is beneficial to changing the dust removal efficiency of the electric dust remover.
It is understood that the first connecting member 130 may have other connecting structures besides the above-mentioned rod structure, and is not limited in particular. The second connecting member 160 may be an angle steel connecting member or a metal plate, one end of the metal plate is fixed to the cathode suspension beam, and the other end of the metal plate is provided with a second mounting hole 161 for penetrating the first connecting member 130.
Further, referring to fig. 1 to 3, the first connecting member 130 includes a pin shaft seat 131 and a pin shaft 132 passing through the pin shaft seat 131, the pin shaft seat 131 is movably connected to the cathode hanging beam 110, the pin shaft 132 is disposed in the pin shaft seat 131, and an end of the pin shaft 132 extends out of the pin shaft seat 131 and is connected to the cathode wire 120. Specifically, the cathode hanging beam 110 is provided with a waist-shaped hole, the width of the waist-shaped hole is smaller than the outer diameter of the pin shaft seat 131, the width of the waist-shaped hole is larger than or equal to the inner diameter of the pin shaft seat 131, and the length of the waist-shaped hole is larger than the outer diameter of the pin shaft seat 131. Thus, the pin shaft seat 131 does not pass through the kidney-shaped hole, but only outside the kidney-shaped hole, but the pin shaft 132 can pass through the kidney-shaped hole. Thus, one end of the pin 132 is inserted into the pin holder 131, and the other end of the pin 132 is connected to the cathode ray 120 through the kidney hole. The other end of the pin 132 is connected to the cathode line 120 by screwing. It is understood that the pin 132 and the cathode wire 120 may be connected together by welding or other methods. And is not particularly limited herein. Thus, when the pushing member 140 drives the cathode wire 120 to move, the cathode wire 120 drives the pin shaft 132 and the pin shaft seat 131 to move along the kidney-shaped hole, and finally the cathode wire 120 moves relative to the cathode hanging beam 110, so that the distance from the cathode wire 120 to the anode plate 150 can be adjusted, and the dust removal efficiency of the electric dust remover can be changed.
In one embodiment, referring to fig. 5, the pushing members 140 are disposed corresponding to the cathode lines 120, the pushing members 140 are connected to the cathode lines 120, and when the pushing members 140 move, the pushing members 140 drive the cathode lines 120 to move. Since the pushing member 140 and the cathode wire 120 are connected, when the pushing member 140 moves, the cathode wire 120 moves along with the pushing member, and the first connecting member 130 connected to the cathode wire 120 also moves along the length direction of the cathode suspension beam 110, so that the cathode wire 120 moves relative to the cathode suspension beam 110, thereby adjusting the distance from the cathode wire 120 to the anode plate 150.
As another alternative, please refer to fig. 1 and fig. 2, two side surfaces of the cathode line 120 respectively abut against at least one pushing member 140, and the pushing member 140 abuts against the side surface of the cathode line 120. When the pushers 140 on the two sides of the cathode line 120 move in the same direction for an equal distance, the pushers 140 drive the cathode line 120 to move. Since the pushers 140 and the cathode lines 120 are in an interference relationship, the pushers 140 on both sides of the cathode lines 120 sandwich the cathode lines 120. When the pushers 140 on both sides of the cathode line 120 move in the same direction for an equal distance, the cathode line 120 clamped between the pushers 140 also moves in the same direction for an equal distance, and the first connecting member 130 connected to the cathode line 120 also moves in the length direction of the cathode suspension beam 110, so that the cathode line 120 moves relative to the cathode suspension beam 110, and the distance from the cathode line 120 to the anode plate 150 can be adjusted.
Further, referring to fig. 1 and 2, the cathode hanging beam 110 has a fixing portion 112 on a surface thereof facing the cathode line 120, and the pushing member 140 is movably connected to the fixing portion 112. Specifically, the fixing portion 112 is provided with a through hole (not shown), and the pushing member 140 is inserted into the through hole.
Referring to fig. 5, when the pushing members 140 and the cathode lines 120 are disposed in a one-to-one correspondence, the fixing portions 112 and the cathode lines 120 are also disposed in a one-to-one correspondence. A fixing part 112 is provided at one side of a cathode line 120, and a pushing part 140 is connected to the cathode line 120 after passing through a through hole of the fixing part 112. At this time, only the pushing member 140 needs to be controlled to move relative to the fixing portion 112, the pushing member 140 drives the cathode wire 120 to move toward the direction close to the fixing portion 112 or away from the fixing portion 112, and the first connecting member 130 connected to the cathode wire 120 is also driven by the cathode wire 120 to move along the length direction of the cathode hanging beam 110, so that the cathode wire 120 finally moves relative to the cathode hanging beam 110.
Referring to fig. 2, when two side surfaces of the cathode line 120 respectively abut against at least one pushing member 140, two sides of one cathode line 120 are respectively provided with a fixing portion 112. Specifically, the fixing portion 112 is provided with a through hole, and the pushing member 140 is disposed through the through hole. The pushing members 140 on both sides of the cathode line 120 respectively penetrate through the through holes of the fixing portions 112 on both sides of the cathode line 120 and then abut against the cathode line 120. At this time, it is only necessary to move the pushing members 140 on both sides of the cathode line 120, so that the pushing members 140 move relative to the fixing portion 112, and the pushing members 140 on both sides of the cathode line 120 move in the same direction, and the cathode line 120 sandwiched between the pushing members 140 also moves. The first connecting member 130 connected to the cathode wire 120 is also moved along the length direction of the cathode hanging beam 110 by the cathode wire 120, and finally the cathode wire 120 is moved relative to the cathode hanging beam 110. Since the anode plate 150 is fixedly disposed in the cathode frame 100, the distance between the cathode wire 120 and the anode plate 150 is changed after the cathode wire 120 moves, thereby changing the dust removing efficiency of the electric dust remover. Thus, a better dust removal effect can be obtained by continuously adjusting the position of the cathode line 120 relative to the anode plate 150.
Specifically, referring to fig. 2, the fixing portion 112 is a flat steel, and the pushing member 140 is an adjusting bolt. The flat steel is disposed on a surface of the cathode hanging beam 110 facing the cathode wire 120, and a length direction of the flat steel is perpendicular to a length direction of the cathode hanging beam 110.
The flat steels are arranged on the cathode hanging beam 110 in parallel and at a certain distance, and a cathode wire 120 is arranged between every two flat steels. The flat steel is provided with a through hole, and the adjusting bolt is arranged in the through hole in a penetrating way and abutted to the cathode wire 120. The adjusting bolt is provided with a nut in a penetrating mode, and the adjusting bolt is screwed up through the nut after penetrating through the through hole, so that the adjusting bolt is fixed on the flat steel. When the cathode wire 120 needs to be moved, the nuts are loosened, and the adjusting bolts on the two sides of the cathode wire 120 are moved, so that the adjusting bolts move relative to the flat steel, and the adjusting bolts on the two sides of the cathode wire 120 need to move towards the same direction, so that the cathode wire 120 clamped between the adjusting bolts also moves along with the adjusting bolts. The first connecting member 130 connected to the cathode wire 120 is also moved along the length direction of the cathode hanging beam 110 by the cathode wire 120, and finally the cathode wire 120 is moved relative to the cathode hanging beam 110. After the cathode lines 120 move, the distance between the cathode lines 120 and the anode plate 150 is also changed, thereby changing the dust removal efficiency of the electric dust remover. As another alternative, a flat steel is disposed on only one side of the cathode wire 120, a through hole is formed in the flat steel, and an adjusting bolt is inserted into the through hole and connected to the cathode wire 120. The end of the adjusting bolt is welded or screwed to the cathode wire 120. The adjusting bolt is provided with a nut in a penetrating mode, and the adjusting bolt is screwed up through the nut after penetrating through the through hole, so that the adjusting bolt is fixed on the flat steel. When the cathode wire 120 needs to be moved, the nut is only required to be unscrewed, and then the adjusting bolt on one side of the cathode wire 120 is moved, so that the adjusting bolt moves relative to the flat steel, and the cathode wire 120 connected with the adjusting bolt also moves along with the adjusting bolt. The first connecting member 130 connected to the cathode wire 120 is also moved along the length direction of the cathode hanging beam 110 by the cathode wire 120, and finally the cathode wire 120 is moved relative to the cathode hanging beam 110. After the cathode lines 120 move, the distance between the cathode lines 120 and the anode plate 150 is also changed, thereby changing the dust removal efficiency of the electric dust remover.
It is understood that the fixing portion 112 may have other structures such as a metal ring fixed on the surface of the cathode suspension beam 110 facing the cathode wire 120, besides the flat steel. And the adjusting bolt penetrates through the metal ring and then the nut is screwed down, so that the adjusting bolt is fixed on the metal ring. Therefore, the specific structure of the fixing portion 112 is not limited herein. The pushing member 140 may be a screw rod or the like, instead of an adjusting bolt, and is not limited herein.
In one embodiment, referring to fig. 1, a wet electric dust collector includes a housing 300 and the cathode frame 100 according to any of the above embodiments, wherein the cathode frame 100 is disposed in the housing 300. Since the wet electric precipitator includes the cathode frame 100 described above, the technical effects are brought by the cathode frame 100, and the beneficial effects already include the beneficial effects of the cathode frame 100, so that no further description is provided herein.
This negative pole frame 100 need not use and prevents the pendulum rod, only needs impeller 140 to drive the removal of negative pole line 120, effectively reduces wet-type electrostatic precipitator's height, also can prevent to produce the creepage phenomenon in the wet-type electrostatic precipitator simultaneously, guarantees electrostatic precipitator's normal operating.
