Description

Technical Field

[0001] This invention relates to the field of installation structure technology, and more specifically, to an installation structure for a wall-mounted reheater soot blower. Background Technology

[0002] A wall-mounted reheater is a thermal device primarily used to improve the thermal efficiency of boiler burners. It reheats the exhaust gas during combustion to a higher temperature, allowing a portion of it to be further utilized by the boiler. A soot blower, on the other hand, is a device used to clean flue gas or ash from a boiler or combustion equipment. Its function is to remove ash from inside the combustion equipment by spraying high-speed airflow or vibration, thus maintaining the normal operation and high efficiency of the equipment. Therefore, a wall-mounted reheater soot blower refers to a device installed on a wall-mounted reheater for removing ash.

[0003] Currently, installing soot blowers on wall-mounted reheaters typically requires drilling holes in the reheater. This drilling damages the soot blowers, making them more prone to leaks and shortening the reheater's lifespan. Furthermore, multiple soot blowers are needed to clean the ash and debris from the reheater, increasing installation costs. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a wall-mounted reheater sootblower installation structure that is easy to install, reduces damage to the inlet and outlet headers, thereby extending the service life of the inlet and outlet headers, and facilitates comprehensive cleaning of ash and slag on the wall-mounted reheater.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An installation structure for a wall-mounted reheater sootblower includes an installation assembly and an adjustment assembly. The installation assembly includes an inlet header and an outlet header. Multiple mounting rings are provided at the bottom of both the inlet and outlet headers. Placement grooves are provided on both sides of the top of each mounting ring. A groove is connected to one end of each placement groove. A movable groove is connected to both the upper and lower ends of each groove. A rotating shaft is provided on the inner wall of each movable groove. An adjustment plate is fixedly connected to the outer wall of the rotating shaft. A stop block is rotatably connected to the front end of each adjustment plate. The upper and lower ends of each stop block are slidably connected to the upper and lower ends of the placement groove and the groove, respectively. A tension spring is fixedly connected to one end of each groove. The outer ends of each tension spring are fixedly connected to one end of the inner side of the adjustment plate. A fixing groove is connected to the front end of each placement groove.

[0007] The present invention is further configured such that: the top of the inlet manifold and the outlet manifold are provided with a plurality of mounting rings one, the number of mounting rings one and mounting rings two are the same, and the bottom of the mounting rings one is provided at the top of the mounting rings two.

[0008] The present invention is further configured such that: both sides of the bottom end of the mounting ring are fixedly connected to a fixing post, the fixing post is L-shaped, the fixing post and the fixing groove are matched, and the rear end of the fixing post is set at the front end of the stop block and the stop block limits the fixing post.

[0009] The present invention is further configured such that the shape of the fixing post and the placement groove are matched, and the fixing post slides on the placement groove.

[0010] The present invention is further configured such that: slots are provided on both sides of the front end of the second mounting ring, and the left and right ends of the inlet manifold and the outlet manifold are fixedly connected with card plates corresponding to the front side of the second mounting ring, and the card plates and slots are shaped to fit each other.

[0011] The present invention is further configured such that: the adjustment component includes two bases, each of the two bases having a sliding groove at one end opposite to the other, the rear end of each sliding groove being rotatably connected to a threaded rod, the outer wall of each threaded rod being threadedly connected to a slider, and the outer end of each slider being slidably connected to one end of the outer side of the sliding groove.

[0012] The present invention is further configured such that: each of the inner ends of the slider is provided with an installation groove, the top of the outer end of the installation groove is rotatably connected to the soot blower body, the bottom of the outer end of the installation groove is rotatably connected to a hydraulic rod, and the driving end of the hydraulic rod is rotatably connected to the bottom end of the soot blower body.

[0013] The present invention is further configured such that: a motor is fixedly connected to the front end of each of the bases, and the motor drive end is fixedly connected to the front end of the threaded rod.

[0014] The present invention is further configured such that the bottom end of each base is fixedly connected to the top end of the mounting ring and is positioned above the inlet manifold and the outlet manifold.

[0015] The present invention is further configured such that: multiple reheater pipes are fixedly connected to the bottom of the inlet header and the outlet header; an inlet pipe is fixedly connected to the front end of the inlet header; and an outlet pipe is fixedly connected to the front end of the outlet header.

[0016] The advantages of this invention are:

[0017] 1. The soot blower can be directly installed on the inlet and outlet manifolds via the snap-fit ​​structure on mounting ring one and mounting ring two. This is convenient, quick, and efficient, and eliminates the need for drilling holes in the inlet and outlet manifolds, thus reducing damage to them and extending their service life.

[0018] 2. By setting the sootblower bodies relative to each other, only two opposing sootblower bodies are needed for cleaning. The position and angle of the sootblower bodies can be adjusted and they are arranged in a cross shape, which facilitates comprehensive cleaning of ash and slag on the wall-mounted reheater. Moreover, it is not necessary to install multiple sootblower bodies to complete the ash and slag cleaning, thereby reducing installation costs. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figure 1-7 The present invention provides the following technical solutions:

[0031] Specifically, a wall-mounted reheater sootblower installation structure is provided, including an installation component 1 and an adjustment component 2. The installation component 1 includes an inlet header 104 and an outlet header 105. Multiple installation rings 103 are provided at the bottom of both the inlet header 104 and the outlet header 105. Placement grooves 106 are provided on both sides of the top of the installation rings 103. A groove 111 is connected to one end of the inner side of each placement groove 106. A movable groove 108 is connected to both the upper and lower ends of the groove 111. A rotating shaft 109 is provided on the inner wall of each movable groove 108. An adjustment plate 107 is fixedly connected to the outer wall of the rotating shaft 109. A stop block 113 is rotatably connected to the front end of each adjustment plate 107. The upper and lower ends of the stop block 113 are slidably connected to the upper and lower ends of the placement groove 106 and the groove 111, respectively. A tension spring 110 is fixedly connected to one end of the inner side of each groove 111. The outer end of the tension spring 110 is fixedly connected to one end of the inner side of each adjustment plate 107. A fixing groove 112 is connected to the front end of each placement groove 106.

[0032] To further explain, both the inlet header 104 and the outlet header 105 are provided with multiple mounting rings 101 at their tops. The number of mounting rings 101 and mounting rings 103 is the same. The bottom of each mounting ring 101 is located at the top of the mounting ring 103. The mounting rings 101 and 103 are installed on the inlet header 104 and the outlet header 105, and are symmetrically arranged during installation.

[0033] To further explain, both sides of the bottom end of the mounting ring 101 are fixedly connected to fixing posts 115. The fixing posts 115 are L-shaped and fit the shape of the fixing groove 112. The rear ends of the fixing posts 115 are set at the front end of the stop block 113, and the stop block 113 limits the fixing posts 115. During installation, the fixing posts 115 are inserted into the fixing groove 112, and the stop block 113 limits the fixing posts 115 to prevent them from sliding out after installation, thus achieving installation. It also protects the inlet manifold 104 and the outlet manifold 105, avoiding drilling in the inlet manifold 104 and the outlet manifold 105.

[0034] To further explain, the fixed post 115 and the placement groove 106 are shaped to fit together, and the fixed post 115 slides on the placement groove 106. Because the shapes fit together, installation is convenient and quick, and during installation, the fixed post 115 needs to be slid along the surface of the placement groove 106.

[0035] To further explain, slots 114 are provided on both sides of the front end of the second mounting ring 103. The left and right ends of the inlet header 104 and the outlet header 105 are fixedly connected to the front side of the second mounting ring 103. The shapes of the slots 114 and the slots 102 are matched. During installation, the slots 114 are first snapped onto the slots 102. There is friction between the slots 102 and the slots 114. Therefore, the friction can prevent the slots 114 from slipping off the slots 102, thereby preventing the second mounting ring 103 from slipping off the slots 102. This makes the second mounting ring 103 tightly snapped onto the lower surface of the inlet header 104 and the outlet header 105, thereby achieving basic installation.

[0036] Further explanation: The adjustment component 2 includes two bases 204. Each base 204 has a sliding groove 201 at one end opposite to the others. A threaded rod 202 is rotatably connected to the rear end of each sliding groove 201. A slider 205 is threadedly connected to the outer wall of each threaded rod 202. One end of each slider 205 is slidably connected to the outer end of the sliding groove 201. An installation groove is provided on the inner end of each slider 205. A sootblower body 203 is rotatably connected to the top of the outer end of each installation groove. A hydraulic rod 207 is rotatably connected to the bottom of the outer end of each installation groove. The driving end of each hydraulic rod 207 is rotatably connected to the bottom end of the sootblower body 203. A motor 206 is fixedly connected to the front end of each base 204. The driving end of each motor 206 is fixedly connected to the front end of the threaded rod 202.

[0037] In addition, by starting the motor 206, the threaded rod 202 is rotated. The threads of the threaded rods 202 on both sides are symmetrical, and the rotation directions on both sides of the threaded rod 202 are opposite. Due to the thread effect of the threaded rod 202, the slider 205 moves backward, changing the position of the sootblower body 203. The hydraulic rod 207 is started, which moves the sootblower body 203 downward, thereby changing the angle of the sootblower body 203 to a cross state. Therefore, it is convenient to clean the ash and slag at different locations on the reheater pipe 4. Moreover, it is not necessary to install multiple sootblower bodies 203 to complete the ash and slag cleaning, thereby reducing the installation cost.

[0038] To further explain, the bottom of the base 204 is fixedly connected to the top of the mounting ring 101 and is positioned above the inlet header 104 and the outlet header 105. The base is installed on the inlet header 104 and the outlet header 105 through the mounting ring 101.

[0039] To further explain, multiple reheater pipes 4 are fixedly connected to the bottom of the inlet header 104 and the outlet header 105. The reheater pipes 4 reheat the steam to make it superheated steam. An inlet pipe 5 is fixedly connected to the front end of the inlet header 104, and an outlet pipe 3 is fixedly connected to the front end of the outlet header 105. Steam enters from the inlet pipe 5, while superheated steam exits from the outlet pipe 3.

[0040] The working principle of the wall-mounted reheater sootblower installation structure provided by this invention is as follows: First, align the slot 114 on the mounting ring 103 with the clamping plate 102, and then install the mounting ring 103 on the clamping plate 102, thereby installing it on the inlet header 104 and the outlet header 105. Since the inner diameter of the mounting ring 103 is the same as the outer diameter of the inlet header 104 and the outlet header 105, it fits tightly during installation to prevent loosening. Then, place the mounting ring 101 on the mounting ring 103, and position the fixing post 115 along the placement groove 1. 06. During sliding, the device contacts the adjusting plate 107 and presses the front part of the adjusting plate 107, causing the front of the adjusting plate 107 to move inward, along with the stop block 113. Simultaneously, the rotating shaft 109 moves backward and stretches the tension spring 110, causing the stop block 113 to fully enter the groove 111. When the fixing post 115 fully enters the fixing groove 112, the restriction on the stop block 113 is released. The resetting action of the tension spring 110 resets the adjusting plate 107, causing the rotating shaft 109 to move forward, while the stop block 113 moves outward. The motor 206 moves and limits the fixing post 115, thereby limiting and fixing the mounting ring 101. This fixes the mounting ring 101 and mounting ring 103 onto the inlet header 104 and outlet header 105, facilitating installation and increasing efficiency. Installation can be performed without drilling holes in the inlet header 104 and outlet header 105, thus protecting them and extending their service life. Furthermore, the motor 206 drives the threaded rod 202... The screw rods 202 on both sides rotate in opposite directions, while the screws on both sides rotate in opposite directions. Due to the screw effect of the screw rods 202, the slider 205 moves backward, changing the position of the sootblower body 203. The hydraulic rod 207 then moves the sootblower body 203 downward, thus changing the angle of the sootblower body 203 to a cross state. This facilitates the cleaning of ash and slag at different locations on the reheater pipe 4, and the cleaning of ash and slag can be completed without installing multiple sootblower bodies 203, thereby reducing installation costs.
