Description

Technical Field

[0001] This invention relates to the field of electrostatic precipitator anode plate installation technology, specifically to an anode plate conveying device based on a BEH type electrostatic precipitator. Background Technology

[0002] Electrostatic precipitators are currently widely used in industries such as thermal power generation, chemical industry, cement and building materials industry, and metallurgical and mining industry for flue gas dust removal, coal ash treatment, dust control, and material recycling. The anode plate is the core component of the electrostatic precipitator. The acceptance criteria for the anode plate are: straight, high strength, high rigidity, and not easily twisted.

[0003] The BEH type electrostatic precipitator is a high-efficiency and energy-saving electrostatic precipitator, characterized by its small footprint, high degree of automation, simple operation and maintenance, and high dust removal efficiency. It is now widely used in various industries. The anode and cathode system is a key component of the BEH type electrostatic precipitator, and its installation quality has a significant impact on the dust removal efficiency after the precipitator is put into operation. Among them, the deformation control of the anode plate is the key to the installation quality of the anode plate.

[0004] The BEH type electrostatic precipitator uses BE plates as anode plates, and a typical anode plate array consists of 5 BE plates. Each BE plate is rolled from a 1.2–1.5 mm thick sheet, with a flat center and hooked ends. The anode plate array consists of 5 BE plates fixed at both ends with fixing plates. It is typically about 15 meters long and 2 meters wide, with approximately 900 arrays. Currently, the anode plate arrays are mainly transported manually, stacked, and handled manually. During transport, the uneven stress on the long and heavy plates can easily cause bending, resulting in inconsistent spacing between the plates and reducing the efficiency of the electrostatic precipitator.

[0005] Utility model patent CN 201470479 U discloses an anti-sway device for anode plates in an electrostatic precipitator. To address the problems of existing anti-sway devices for anode plates, such as difficulty in installation, high cost, and difficulty in ensuring the spacing between anode plates, this utility model connects the lower end of the anode plate to the electrostatic precipitator housing via anti-sway rods. Several anti-sway rods are set at specified intervals on the anode plate between the suspension rod and the anti-sway rods. This provides advantages such as convenient processing, transportation, and installation, ensuring the spacing between anode plates, and improving dust removal efficiency. However, the aforementioned patent uses anti-sway rods to fix the anode plates, only for fixing them during use, and does not explain how to improve the efficiency of anode plate handling during transport.

[0006] Therefore, given the large number of anode plates in the BEH type electrostatic precipitator, the large size of each group, and the thinness of the plates, after assembly, the anode plates need to be transported into packaging boxes. During hoisting, the anode plates need to be lifted from the packaging boxes onto the hoisting equipment at the hoisting site. Using traditional hoisting methods or manual handling during this process is inefficient, wastes manpower and resources, and easily leads to deformation and damage of the anode plates. Therefore, those skilled in the art urgently need a safe and reliable anode plate transport device that ensures no deformation during transport, greatly reduces anode plate damage, saves manpower, and significantly improves work efficiency. Summary of the Invention

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be described below in conjunction with specific embodiments and accompanying drawings.

[0027] The anode plates used in BEH type electrostatic precipitators are BE plates, and a typical anode plate array consists of 5 BE plates. Each BE plate is rolled from a 1.2–1.5 mm thick coil, with a flat center and hooked ends. The anode plate array consists of 5 BE plates fixed at both ends with fixing plates, typically about 15 meters long and 2 meters wide, with approximately 900 arrays. Therefore, improving the handling quality of the anode plate array during transport and handling is a crucial factor in addressing anode plate array quality issues.

[0028] like Figure 1-7 As shown, an anode plate row transport device based on a BEH type electrostatic precipitator includes a lifting device, which generally uses a large crane. The anode plate row 10 is composed of several anode plates arranged side by side. Hooks perpendicular to the anode plates are provided between the anode plates. The hooks include hook columns perpendicular to the anode plates, hook plates perpendicular to the hook columns and extending towards the central axis of the anode plates, and hooks on both sides extending inward into the anode plates to form inverted "L"-shaped corner hooks 101. Hooks between the anode plates extend to both sides to form "T"-shaped middle hooks 102.

[0029] The anode plate conveying device includes a rigid hanger 20 connected to the lifting device. The rigid hanger has a main frame 201, a lower lifting lug 202, an upper shackle 203, a sling 204, and a lower shackle 205. The sling is connected to the main frame through the upper shackle, and the lower shackle is located below the sling. Two slings are set at the same position on the main frame, and the two slings form a sling group. The sling group is set according to the actual situation. The same position mentioned here is based on the relative position at the same distance from the break point of the main frame, and is not limited to the slings being installed at the same point on the main frame. The main frame is connected to the crane through the upper lifting lug 206.

[0030] The upper and lower shackles are made of 2t finished shackle parts, and the slings can be composed of one or more of the following: wire rope, chain, sling, and strap.

[0031] The anode plate transport device also includes a tooling hoist 30 connected to the anode plate assembly via a lower retaining ring. The tooling hoist includes a main beam 40 connected to a sling via the lower retaining ring, a clamping structure 50 mounted on the main beam for gripping the anode plate assembly, a clamping plate 501 that clamps onto the hook after rotation, and a clamping plate connector for connecting the main beam and the clamping plate. The main beam is perpendicular to the rigid hanger. The clamping plate is made of 10mm steel plate. The length L1 of the clamping plate is greater than the distance L2 between the closest points of the hook plates installed on both sides of the anode plate, and less than the distance L3 between the hook posts set on both sides of the anode plate.

[0032] There are no fewer than two sets of tooling and lifting equipment depending on the length of the anode plate bar. Generally, one set of tooling and lifting equipment is set at a distance of 2 to 3 meters. For a 15-meter-long anode plate bar, four sets of tooling and lifting equipment are usually set.

[0033] The main beam includes a horizontally arranged cross plate 401 and two vertically arranged vertical plates 402 on both sides of the cross plate. The top of the two vertical plates forms an opening 403 in the main beam. The clamping plate connector includes a fixed steel plate 404 installed at the opening of the main beam, a connecting shaft 502 passing through the fixed steel plate and the cross plate, an adjusting plate 503 set above the connecting shaft, and a clamping plate installed below the connecting shaft. The connecting shaft is rotatably connected to the fixed steel plate and the cross plate, and the connecting shaft is fixedly connected to the adjusting plate and the clamping plate. The main frame and the main beam can be assembled and welded using channel steel, angle steel, and small-diameter steel pipes. The cross plate is provided with a main beam lifting lug 405, which is connected to a lower clamping ring. The main beam lifting lug is prefabricated from a 10mm steel plate and welded to the cross plate.

[0034] A limiting platform 5021 is provided above the horizontal plate and below the fixed steel plate for the connecting shaft. The horizontal plate and the fixed steel plate are provided with through holes for installing the connecting shaft. The outer diameter of the limiting platform is larger than the inner diameter of the through hole. The limiting platform is used to limit the position and rotation of the connecting shaft. During installation, after fixing the horizontal plate and the vertical plate, the connecting shaft is placed, and finally the fixed steel plate is placed and welded to the opening of the main beam.

[0035] Multiple sets of snap-fit ​​structures are evenly arranged on the main beam. An adjusting connector is provided between the evenly arranged snap-fit ​​structures. The adjusting connector includes a connecting plate 504. The connecting plate is rotatably connected to the adjusting plate. The connecting plate is sequentially connected to the adjusting plates on the multiple sets of snap-fit ​​structures. When the connecting plate is moved, the adjusting plates rotatably connected to the connecting plate move simultaneously.

[0036] Specifically, when adjusting the connecting plate, an adjusting handle 505 can be set at one end of the connecting plate. The adjusting handle is fixedly connected to the connecting plate. Pulling the adjusting handle moves the connecting plate. In addition to pulling manually, the adjusting handle can also be pulled using a tool. When using a tool, a controller for pushing and pulling the adjusting handle is set on the outside of the vertical plate. The controller includes a servo cylinder and a straight rod driven by the servo cylinder. The front end of the straight rod is rotatably connected to the adjusting handle.

[0037] The rotating connections described above can use existing rotating connection methods such as hole-shaft rotation mode and bearing rotation mode. Fixed connections can be achieved by welding or nut-bolt connection structures or methods.

[0038] Furthermore, when using tools to push and pull the connecting plate, there is another form. Specifically, the snap-fit ​​structure also includes a drive mechanism that drives the snap-fit ​​plate to rotate. The drive mechanism includes a servo hydraulic pump 506 mounted on the horizontal plate. A push-pull rod 507 is provided at the front end of the servo hydraulic pump, and a drive tooth 508 is provided at the front end of the push-pull rod. A driven tooth 509 is provided on the connecting shaft. The drive tooth and the driven tooth mesh. The servo hydraulic pump drives the push-pull rod to move forward or backward. The meshing of the drive tooth and the driven tooth drives the connecting shaft to rotate. When installing the drive structure, it can be installed at only one of the connecting shafts. Usually, the drive mechanism is placed at the outermost connecting shaft. The drive mechanism is installed above or below the horizontal plate depending on the actual situation. When installed above, it is convenient to protect the drive mechanism. When installed below, it is convenient to install.

[0039] Furthermore, in order to prevent the card plate from easily detaching and loosening from the hook, the front end of the hook plate is provided with a hook body 103 facing the anode plate, and the card plate is provided with a groove 510. When the card plate is engaged with the hook, the hook body is engaged in the groove, thereby preventing the card plate from easily detaching from the anode plate.

[0040] Furthermore, when manually pulling the adjustment handle, a pull rope is installed at the top of the handle. After the pull rope is engaged with the hook in the clamping plate, it is used to tighten the adjustment handle and prevent the adjustment handle from becoming loose.

[0041] In use, during the transport of the anode plates of the BEH electrostatic precipitator, the anode plate transport device is used to first lift the rigid frame with hoisting machinery. The rigid frame and tooling are then lifted above the anode plate array. Four sets of tooling are evenly placed on the anode plate array to be hoisted. By operating the adjustment handle or drive mechanism, the clamping plate is engaged with the hooks on both sides of the anode plate array. The hoisting machinery is then directed to hoist and transport the anode plate array. After being transported to the packaging box or hoisting device, the clamping plate is then removed from the hooks on both sides of the anode plate array by operating the adjustment handle or drive mechanism. The BEH electrostatic precipitator anode plate transport device is then moved above the next set of anode plate arrays for hoisting.
