Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic slag removal systems, and relates to a slag collection device for a hydraulic slag removal system in a thermal power plant boiler. Background Technology

[0002] A hydraulic ash removal system is a system used in thermal power plants to remove and transport ash produced after boiler combustion to a specific location using the impact and conveying capacity of water. It mainly includes an ash discharge pool, a transfer pool, and an ash removal machine. Water flows into the ash removal machine and settles at the bottom. A scraper conveying device at the bottom of the machine removes the settled impurities.

[0003] During the operation of boilers in thermal power plants, the practice of co-firing coal to improve economic efficiency has brought positive effects, but it has also led to a large amount of scum in the ash removal pond. The ash removal machine is unable to remove the scum on the water surface, and when the water overflows from the machine, the scum also overflows, causing environmental pollution, affecting the normal operation of the ash removal system, and reducing the system's efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model discloses a scum collection device for a hydraulic scum removal system in a thermal power plant boiler. The device includes a support frame 1, which is a rectangular frame fixedly installed above a transfer pool. A sinking rail 2 is installed inside the transfer pool. The sinking rail 2 includes tracks 21 parallel to both sides of the transfer pool, each track 21 having a sinking block 3 slidably mounted on it. The device also includes a net with four first hooks 41 at its opening. The first hooks 41 are respectively installed at two corners of the support frame 1 and at the sinking block 3. The opening of the net faces the water flow direction of the transfer pool. At least two second hooks 42 are installed at the end of the net furthest from the opening, at the two corners of the support frame 1 furthest from the sinking rail 2.

[0025] Specifically, a support frame 1 is installed above the transfer pool, and a net is hung under the support frame 1. The net is opened in the direction of water flow through the first hook 41, so that the upper layer of water flows through the net.

[0026] In this way, by setting up a sludge net in the upper layer of the water flow, the scum on the surface of the water flow is left in the sludge net as the water flows through it, thereby reducing the amount of scum entering the sludge removal machine.

[0027] In some feasible methods, the support frame 1 is a stainless steel rectangular frame, which is fixedly installed above the transfer pool by bolts. The track 21 is a C-shaped track, which can be made of stainless steel bent parts or opened on the side wall of the transfer pool. The sinking block 3 is used to provide the weight for the sinking of the net, so that the opening side of the net can be submerged in the water. The sinking block 3 and the support frame 1 are equipped with lifting rings to facilitate the attachment of the first hook 41 and the second hook 42. The net is suspended from the support frame 1 by the second hook 42, reducing the impact of the net on the flow of sediment below the water. The net is a pocket-shaped scooping net selected according to the size of the scum particles.

[0028] In some feasible ways, the sinking block 3 is made of ceramic material. The water in the hydraulic slag removal system is a high-temperature and corrosive environment. By using ceramic material, the service life of the sinking block 3 can be improved. At the same time, the track 21 can also be made of corrosion-resistant materials such as high-temperature resistant engineering plastics to improve its service life.

[0029] As a specific embodiment of the slag collection device of the hydraulic slag removal system of a thermal power plant boiler provided in the application, the support frame 1 is connected to two fixing blocks 11, and the first hook 41 is respectively installed on the fixing blocks 11. The fixing blocks 11 are respectively located at the upper end of the sinking rail 2. The sinking block 3 is fixedly installed with a gathering rope 43, which can slide through the fixing block 11.

[0030] Overall, by setting up the drawstring 43, after a certain amount of scum has been collected, the drawstring 43 is tightened to close the opening of the net, making it easy to retract the net to clean the scum or replace the net.

[0031] In some feasible methods, the fixing block 11 is a rectangular block. To facilitate the fixing of the fixing block 11 after placement, the support frame 1 has a through hole at the corresponding position. A connecting plate is provided on the side of the rectangular block, and a positioning pin is inserted into the connecting plate. During installation, the positioning pin is inserted into the corresponding through hole of the support frame 1.

[0032] Furthermore, the drawstring 43 is slidably mounted with an adjustment block 44, which is threadedly connected to a fixing bolt 441. When the fixing bolt 441 is tightened, it abuts against the drawstring 43.

[0033] It should be understood that by setting the adjustment block 44, it is convenient to adjust the lowering length of the gathering rope 43, thereby adjusting the lowering length of the net so that the net can adapt to changes in water level.

[0034] In some feasible ways, the adjusting block 44 is a rectangular block with a through hole in the middle and a threaded hole on the side.

[0035] Furthermore, it also includes a replacement rail 5, which is located in the middle of the support frame 1. The replacement rail 5 has the same structure as the sinking rail 2. A connecting rail 51 is installed at the bottom of the replacement rail 5, and the end of the connecting rail 51 away from the replacement rail 5 is connected to the bottom of the sinking rail 2.

[0036] It should be understood that by setting up the replacement net rail 5 and the connecting rail 51, it is convenient to replace the net after the scum has been collected. After the net is full of scum, the second hook 42 is disengaged, the sinking block 3 of the new net to be replaced is placed into the replacement net rail 5, and the full net is pulled out from the sinking rail 2 by the drawstring rope 43. Then, the sinking block 3 is guided from the replacement net rail 5 along the connecting rail 51 into the sinking rail 2 by the drawstring rope 43, and the drawstring rope 43 is adjusted to a suitable length.

[0037] In some feasible methods, the replacement rail 5 has the same structure as the sinking rail 2. In order to facilitate the movement of the sinking block 3 under the guidance of the coiling rope 43, the sinking block 3 is set as a spherical block, and the two ends of the connecting rail 51 are arc-shaped rails.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
