Background

In the process of fume emission, the fume purification device is used for adsorbing particulate matters or fume in fume, so that the clean exhaust gas is ensured.

Electrostatic fields are widely used in various flue gas cleaning scenarios due to their excellent adsorption properties for soot and particulate matter. However, in the electrostatic field disclosed in the patent number CN215541787U, one end of the insulator is fixedly connected to one side of the frame, and the other end is fixedly connected to the cathode frame. Due to the non-precise structure of the insulator, the threaded mounts Kong Nanyu on both ends of the insulator are coaxial. The screw holes for installing the insulator are produced according to the drawing (namely, the screw holes at the two ends of the insulator are coaxial) on the frame for connecting the cathode frame of the insulator and the electrostatic field, and the screw holes on the shell of the electrostatic field processed according to the drawing cannot normally install the insulator because the screw holes for installing the insulator are different in two times, so that the screw holes on the shell of the electrostatic field can be increased normally, and the insulator can be installed normally. However, after the screw hole on the casing is enlarged, the connection between the insulator and the casing will be unstable, that is, the cathode frame connected with the insulator will be unstable, a plurality of cathode plates connected with the cathode frame may shake under the blowing of the flue gas, and the polar distance in the electrostatic field may change slightly during the flue gas flowing process, so that the electrostatic field is unstable.

Examples

Electrostatic fields are widely used in various dust removing environments due to their excellent dust removing performance. To avoid contact between the cathode frame and the frame or anode plate, an insulator is typically provided between the cathode frame and the mounting frame to ensure that the mounting frame is not charged.

However, in part of the electrostatic field disclosed in CN215541787U, the cathode frame is configured as a square tube, and the convenient side and the inner side of the frame are connected by an insulator. Because the insulator is not a standard component, the axle centers of the mounting holes at two ends of part of the insulator are misplaced. When designing the cathode frame drawing, the insulator is the ideal insulator, and the mounting hole at insulator both ends is on same axis promptly, and the mounting hole of seting up on cathode frame and mounting bracket this moment is coaxial setting too, because the insulator is nonstandard part in fact, and after installing on the cathode frame this moment, on the basis that needs the installation pole on the cathode frame and mounting bracket are perpendicular, the other end of insulator can not align with the through-hole on the mounting bracket.

In order to ensure that the insulator can be normally installed, a mounting hole for mounting the insulator on the mounting frame is required to be reamed. After the mounting holes in the mounting frame are enlarged, a certain gap exists between the bolts for connecting the insulators and the mounting blocks, and the bolts cannot fix the cathode frame well. When flue gas circulates between the cathode plate and the anode plate, the cathode plate fixed through the cathode frame can deviate due to unfixed position of the cathode frame, so that the distance between the cathode plate and the anode plate is changed, and the dust removal efficiency of the electrostatic field is greatly reduced.

The application discloses an electrostatic field, this electrostatic field is integrated square pipe into a platelike cathode holder 40 to through installing insulator 60 between platelike cathode holder 40 and mounting panel 10 opposite two sides, the one end and the cathode holder 40 fixed connection of insulator 60, the other end and mounting panel 10 fixed connection. That is, the insulator 60 is clamped by the cathode frame 40 and the mounting plate 10, and referring to fig. 3, at this time, no matter whether the mounting holes at both ends of the insulator 60 are coaxial, after the mounting plate 10 or the hole for mounting the insulator 60 at the cathode frame 40 is enlarged, the insulator 60 arranged between the plate-shaped cathode frame 40 and the mounting plate 10 can still be well clamped, and the cathode frame 40 and the cathode plate 70 mounted on the cathode frame can still be kept stable in the flue gas flowing process, that is, the polar distance of the electrostatic field is stable, so that the electrostatic field can be ensured to stably purify the flue gas.

Specifically, referring to fig. 1-3, the electrostatic field provided by the present utility model includes two mounting plates 10 disposed in parallel, a first fixing rod 20 is disposed between the two mounting plates 10, and two ends of the first fixing rod 20 are fixedly connected to the two mounting plates 10, respectively. The first fixing rod 20 is mounted with a plurality of anode plates 30 parallel to each other, and the anode plates 30 are spaced apart. For mounting the cathode plate 70, two cathode frames 40 are also provided, and two mounting plates 10 are provided between the two cathode frames 40. A plurality of insulators 60 are provided between the mounting plate 10 and the cathode frame 40, and both ends of the insulators 60 are fixedly connected to opposite sides of the mounting plate 10 and the cathode frame 40, respectively, so that the cathode frame 40 and the mounting plate 10 are parallel. A second fixing rod 50 is provided between the two cathode frames 40, the second fixing rod 50 is provided between the two cathode frames 40 and passes through the mounting plate 10 and the plurality of anode plates 30, and both ends of the second fixing rod 50 are fixedly connected with the two cathode frames 40, respectively, and the second fixing rod 50 is not connected with the anode plates 30. A plurality of cathode plates 70 parallel to the anode plates 30 are mounted on the second fixing bar 50, and the cathode plates 70 are mounted on the second fixing bar 50 between the two mounting plates 10 at a spaced apart interval, in contrast to fig. 3 and 4, when one cathode plate 70 is disposed between two adjacent anode plates 30 and the cathode plates 70 are not connected to the first fixing bar 20.

The cathode plate 70 and the anode plate 30, which are spaced apart and disposed parallel to each other, constitute the plates of the electrostatic field. And the cathode plate 70 is connected with the cathode frame 40, when the cathode frame 40 is electrified, an electrostatic field is formed between the cathode plate 70 and the anode plate 30, and when the smoke passes through the electrostatic field, the smoke and the particulate matters in the smoke are adsorbed on the anode plate 30 under the action of the electrostatic field.

When the insulator 60 is clamped by the cathode frame 40 and the mounting plate 10, whether the mounting holes of the insulator 60 are coaxial or not does not affect the clamping of the insulator 60 by the cathode frame 40 and the mounting plate 10, so that the stability of the cathode frame 40 and the mounting plate 10 is maintained.

For ease of installation, the first securing lever 20 is perpendicular to the mounting plate 10, and the anode plate 30 is parallel to the mounting plate 10. Since the length direction of the insulator 60 can be polished so that the length of the insulator 60 between the cathode holder 40 and the mounting plate 10 is uniform, the plate-shaped cathode holder 40 can be kept parallel to the mounting plate 10, and the second fixing rod 50 is similarly convenient to mount, and the second fixing rod 50 presses the cathode holder 40 against the insulator 60.

The anode plate 30 and the second fixing bars 50, the cathode plate 70 and the first fixing bars 20 cannot be communicated, so that the cathode plate 70 is prevented from being communicated with the anode plate 30. Specifically, as shown in fig. 8 to 11, a first avoiding portion 31 is provided on the anode plate 30, and the first avoiding portion 31 is configured to avoid the second fixing rod 50. The cathode plate 70 is provided with a second escape portion 71, and the second escape portion 71 is configured to escape the first fixing rod 20.

The shapes of the first avoidance portion 31 and the second avoidance portion 71 are not limited, and the first avoidance portion 31 may avoid the second fixing rod 50, and the second avoidance portion 71 may avoid the first fixing rod 20.

Preferably, in an embodiment of the present utility model, in order to facilitate the processing of the first relief portion 31 and the second relief portion 71, punching is generally performed on the cathode plate 70 and the anode plate 30, i.e., circular holes are punched in the cathode plate 70 and the anode plate 30.

The insulators 60 are generally symmetrically positioned to balance the forces on the cathode plate 70.

Because the cathode plate 70 is thinner, six first avoidance portions 31 which are symmetrically arranged are arranged on the anode plate 30, that is, six second fixing rods 50 which are symmetrically arranged are arranged on the anode plate 30 to fix the cathode plate 70.

To avoid the second fixing lever 50, the first fixing lever 20 is disposed at four corners of the mounting plate 10.

In order to make the thinner anode plate 30 more stable during the flue gas flow process, four symmetrical third fixing rods 80 are also provided in the middle of the anode plate 30. Both ends of the third fixing rod 80 are fixedly connected with the mounting plate 10, respectively, and the third fixing rod 80 is connected with the anode plate 30, not with the cathode plate 70.

Preferably, in one embodiment of the present utility model, four insulators 60 are provided between the mounting plate 10 and the cathode frame 40 in order to stabilize the mounting of the thinner cathode frame 40.

In order to facilitate the installation of the insulator 60, the end of the third fixing rod 80 provided at the middle of the anode plate 30 is generally connected to the installation hole of one end of the insulator 60.

Referring to fig. 6 and 7, when the cathode plate 70 or the anode plate 30 has a sufficient strength, only one set of two insulators 60, which are symmetrical, may be provided to fix the cathode plate 70, and as such, the number of the first fixing bars 20 and the second fixing bars 50 should be reduced. When only two first fixing bars 20 are provided, the first fixing bars 20 may be directly connected to the two insulators 60.

It should be understood that the number of the insulators 60, the first fixing bars 20 (the third fixing bars 80, both for fixing the anode plates 30), and the second fixing bars 50 is determined according to the strength of the cathode plates 70 and the anode plates 30. When the cathode plate 70 and the anode plate 30 are thin, the insulator 60, the first fixing rod 20 (the third fixing rod 80, both for fixing the anode plate 30), and the second fixing rod 50 may be provided in several groups, and when the cathode plate 70 and the anode plate 30 have sufficient strength, the insulator 60, the first fixing rod 20 (the third fixing rod 80, both for fixing the anode plate 30), and the second fixing rod 50 may be provided as shown in fig. 7 of the present utility model.

In order to avoid that the flue gas contaminates the insulator 60 to make the cleaning period of the electrostatic field shorter, in combination with fig. 1 and 3, the first polar plate close to the mounting plate 10 is generally set as the anode plate 30, so that the mounting plate 10 does not act as the anode plate 30 to adsorb the flue gas, and simultaneously adsorbs the flue gas close to the mounting plate 10, so that the speed of the insulator 60 polluted by the flue gas is slowed down, and the cleaning period of the whole electrostatic field is prolonged.

In order to facilitate the installation of the cathode plate 70 and the anode plate 30, the first fixing lever 20, the second fixing lever 50, and the third fixing lever 80 adopt the same structure. In this application, the first fixing rod 20 is taken as an example, and the structures of the second fixing rod 50 and the third fixing rod 80 are similar to those of the first fixing rod 20, so that the description thereof will be omitted.

Referring to fig. 14, the first fixing rod 20 includes a first core rod 21 and a plurality of first sleeve rods 22, wherein the first core rod 21 passes through a plurality of anode plates 30 and both ends of the core rod and the mounting plate 10 are fixedly coupled by nuts.

Specifically, the first core rod 21 is threaded at both ends, and the unthreaded section of the first core rod 21 has an outer diameter larger than that of the mounting plate 10 at which the first core rod 21 is mounted. The unthreaded section of the first core rod 21 has an outer diameter that is smaller than the outer diameter of the bore in the anode plate 30 for passing through the first core rod 21. The first sleeve rod 22 is sleeved on the outer wall of the first core rod 21, and two adjacent first sleeve rods 22 are used for clamping the anode plate 30.

At least two first rods 22 have a length, one first rod 22 having a length equal to the spacing between the mounting plate 10 and the adjacent anode plate 30, and one first rod 22 having a length equal to the spacing between the adjacent anode plates 30.

Similarly, the second fixing rod 50 includes a second core rod and a second stem 52, and the third fixing rod 80 includes a third core rod and a third stem.

In the mounting, the first core bar 21 and the second core bar are first fixed to the mounting plate 10 by nuts, and then the insulator 60 and the third core bar corresponding to the mounting plate 10 on the side are fixed, and the cathode frame 40 is mounted on the insulator 60.

The second and third loop bars 52, 52 likewise have a variety of lengths to suit their installation environment.

After the first core rod 21, the second core rod, and the third core rod are installed, the first rod 22 and the third rod are sequentially placed, and then the anode plate 30 is allowed to be placed. After the second stem 52 is placed on the second core rod, the cathode plate 70 is placed on the second stem 52.

The above steps are repeated to sequentially place the cathode plate 70 and the anode plate 30 at intervals.

Then, the first core bar 21 is fixed by the nut, the insulator 60 at the other side mounting plate 10 is fixed to the third core bar, the cathode plate 70 at the other side is fixed to the insulator 60, and then the second core bar is fixed to the cathode frame 40 by the nut.

In order to make the polar plate not easy to deform due to external interference, a corner protector 90 is usually arranged between the two mounting plates 10, and two ends of the corner protector 90 are respectively fixedly connected with the two mounting plates 10. As shown in fig. 1-2 and 4, corner protector 90 wraps the corners of anode plate 30 to prevent anode plate 30 from being deformed by force.

The corner protector 90 is typically fixedly attached to the mounting plate 10 by means of core back nails, thereby making the electrostatic field more stable. Meanwhile, the loose core nails are easy to detach, so that the maintenance of the electrostatic field is convenient.

To avoid communication between the cathode plate 70 and the anode plate 30, the forward projection of the cathode plate 70 is within the forward projection of the anode plate 30 so that the cathode plate 70 and the corner protector 90 do not come into contact.

Further, in order to make the corner protector 90 have a better protection effect on the anode plate 30, as shown in fig. 12 to 13, grooves 91 are provided on the corner protector 90 to be matched with the number of the anode plates 30, and the grooves 91 are used for limiting the anode plates 30. I.e., the width of the recess 91 is slightly greater than the thickness of the anode plate 30, so that the characters of the anode plate 30 are well constrained, and the polar distance of the electrostatic field is stable.

Referring to fig. 4 or 6, the mounting plate 10 is generally provided as a "" shaped mounting plate 10, and the cathode frame 40 is disposed within the opening of the mounting plate 10 so that the rigidity of the mounting plate 10 is enhanced. While the uncharged mounting plate 10 surrounds the charged cathode frame 40 to avoid human false touches.

As shown in fig. 5, in order to facilitate holding of the electrostatic field, a hand-held portion is provided on the cathode holder 40, and the sheet metal at the hand-held portion is bent inward so that the sheet metal at the place is not cut by hand.

The utility model also discloses an installation method of the electrostatic field, which is used for installing the electrostatic field. The method comprises the following steps:

step S1): taking a mounting plate 10, fixedly connecting one end of a first core rod 21 to one side of the mounting plate 10, fixedly connecting one end of an insulator 60 to the opposite side of the mounting plate 10, fixedly connecting the other end of the insulator 60 to a cathode plate 70, and fixedly connecting one end of a second core rod with the cathode plate 70 by penetrating through the mounting plate 10;

step S2): the first sleeve rod 22 and the anode plate 30 are placed on the first core rod 21 in sequence, the second sleeve rod 52 and the cathode plate 70 are placed on the second core rod, and one anode plate 30 is placed after one cathode plate 70 is placed;

step S3): another mounting plate 10 is fixedly connected to the other end of the first core rod 21;

step S4): taking a corner protector 90, and respectively connecting two ends of the corner protector 90 with two mounting plates 10;

step S5): an insulator 60 is fixedly attached to the other mounting plate 10, and the other cathode frame 40 is mounted on the insulator 60 after the insulator 60 is mounted.

Then, the first core rod 21 is fixed by a nut, the insulator 60 at the mounting plate 10 at the other side is fixed to the third core rod, the cathode plate 70 at the other side is fixed to the insulator 60, and then the second core rod is fixed to the cathode frame 40 by a nut, thereby completing the installation of the electrostatic field.
