Description

Technical Field

[0001] This utility model relates to the field of oxidation furnace technology, and in particular to a dual-channel device for buried scrapers. Background Technology

[0002] Submerged scraper conveyors are continuous conveying equipment used for horizontal, inclined, or vertical transport of bulk materials, widely used in mining, metallurgy, chemical, and building materials industries. Submerged scraper conveyors transport materials through a closed trough and an internal scraper chain. During operation, a motor drives a sprocket, which in turn moves the scraper chain. The material moves along the trough under the push of the scrapers until it is discharged from the discharge port. In existing technologies, the scraper route from the submerged scraper conveyor of the electrostatic precipitator in the oxidizer to the granulation workshop is long, and malfunctions are inevitable during long-term operation. During normal production, the amount of soot is large. When a part of the submerged scraper conveyor entering the granulation workshop malfunctions, it is necessary to stop the machine for repair, which affects the operation of the entire production line, leading to reduced production efficiency and output, thus its practicality needs improvement. Therefore, we propose a dual-channel submerged scraper conveyor device. Summary of the Invention

[0003] To solve the above problems, this utility model provides a dual-channel device for buried scraper.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a dual-channel buried scraper conveyor device, including a buried scraper conveyor 1 with a first ash discharge pipe and a second ash discharge pipe connected to its top. Two sets of ash feeding mechanisms are provided below the buried scraper conveyor 1. Each ash feeding mechanism includes a second buried scraper conveyor and an ash feeding pipe connected to the first buried scraper conveyor. A gate valve is installed on the ash feeding pipe, and its bottom end is connected to the second buried scraper conveyor. An ash discharge valve is also installed on the ash feeding pipe. A support frame 1 is installed at the bottom of the first buried scraper conveyor, and a support frame 2 is installed at the bottom of the second buried scraper conveyor. A moving wheel is installed at the bottom of the second support frame, and a distance adjustment mechanism is provided between adjacent second support frames. A dwelling component is provided at the bottom of the second support frame.

[0006] In the above scheme, the distance adjustment mechanism includes a connecting arm 1 connected to a support frame 2 on one side, and a connecting arm 2 connected to the support frame 2 on the other side, wherein the connecting arm 1 and the connecting arm 2 are movably connected.

[0007] In the above scheme, a limiting post is vertically fixed at the end of the second connecting arm, and a moving groove adapted to the limiting post is opened along the length direction of the first connecting arm. The end of the limiting post is locked to the first connecting arm by a nut.

[0008] In the above scheme, the dwelling component includes a dwelling plate, and movable rods are fixed at the top of both ends of the dwelling plate. The top of the movable rods is movably connected to the second support frame.

[0009] In the above scheme, the top of the moving rod is connected to a ball bearing seat, a ball bearing is installed in the ball bearing seat, and a rolling groove that cooperates with the ball bearing is opened on the second support frame. The rolling groove is in the shape of a "7".

[0010] In the above scheme, a plug pipe is connected to one bottom of the buried scraper conveyor, and the ash delivery pipe is connected to the plug pipe.

[0011] In the above scheme, a rubber block is connected to the bottom of the retention plate.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a submerged scraper conveyor and two sets of ash feeding mechanisms, the submerged scraper conveyor first transports the flue dust from ash discharge pipe one and ash discharge pipe two to the next stage. Then, in conjunction with the ash feeding pipe, the flue dust in the scraper conveyor first is fed downwards into the submerged scraper conveyor second. Compared with the prior art, when one of the submerged scraper conveyors second malfunctions, there is no need to stop the entire production line. Simply close the gate valve on the malfunctioning side and the ash discharge valve to stop ash discharge. Then, open the gate valve on the ash feeding pipe on the other side and open the ash discharge valve on that side to transport the flue dust in the submerged scraper conveyor first, avoiding disruption to the entire production line operation and preventing any impact on production efficiency. To ensure output and effectively improve practicality, a moving wheel and distance adjustment mechanism are installed. Different production lines have different ash feeding pipe positions. The moving wheel adjusts the distance between connecting arm one and connecting arm two. Nuts are then used to lock the limiting post and connecting arm one, locking them together and achieving the desired distance adjustment. A dwelling assembly is installed. By adjusting the position of the moving rod along the rolling groove, the dwelling plate moves up and down. When the dwelling plate is at the same height as the moving wheel, it abuts against the ground, increasing the contact area and friction. This prevents the support frame two from sliding under the movement of the moving wheel, improving the stability of the scraper conveyor two. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a buried scraper dual-channel device, including a buried scraper conveyor 1 with a first ash pipe 2 and a second ash pipe 3 connected to the top. The first ash pipe 2 and the second ash pipe 3 are respectively the ash pipe of the waste heat boiler and the ash pipe of the electrostatic precipitator. Two sets of ash feeding mechanisms are provided below the buried scraper conveyor 1. The ash feeding mechanism includes a second buried scraper conveyor 8 and an ash feeding pipe 5 connected to the first buried scraper conveyor 1. The buried scraper conveyor 1 and the second buried scraper conveyor 8 in the figure are partial structures, and their lengths are set according to actual application requirements. Both the first buried scraper conveyor 1 and the second buried scraper conveyor 8 are chain driven and driven by a servo motor. The buried scraper is divided into upper and lower layers, and the conveying order of the upper and lower layers of buried scraper is opposite.

[0021] Specifically, during the production of the oxidizer, the flue gas produced is cooled by the waste heat boiler. Some of the soot will enter the buried scraper conveyor 1 from the ash discharge pipe 2. The flue gas then enters the electrostatic precipitator. While cooling the flue gas, the electrostatic precipitator also removes dust from the flue gas. The soot in the flue gas will fall onto the anode plate and the bottom of the electrostatic precipitator, and then fall into the buried scraper conveyor 1 along the ash discharge pipe 23.

[0022] Furthermore, the bottom of the buried scraper conveyor 1 is connected to the insertion pipe 4, and the ash conveying pipe 5 is sealed to the insertion pipe 4. At the same time, the bottom end of the ash conveying pipe 5 is connected to the buried scraper conveyor 2 8 through a rotary joint, so that the ash conveying pipe 5 can be disassembled from the buried scraper conveyor 1. When the ash conveying pipe 5 is blocked due to excessive dust accumulation, it is convenient to repair the ash conveying pipe 5.

[0023] Specifically, such as Figure 1 As shown, the right-side submerged scraper conveyor 28 is the conveying line from the oxidation furnace to the granulation workshop, while the other-side submerged scraper conveyor 28 is the conveying line from the reduction furnace to the granulation workshop. The ash-feeding pipe 5 connected to the right-side submerged scraper conveyor 28 is the ash-feeding pipe for the oxidation furnace, and the other-side ash-feeding pipe 5 is the ash-feeding pipe for the reduction furnace.

[0024] A slide valve 6 is installed on the ash conveying pipe 5. The bottom end of the ash conveying pipe 5 is connected to the buried scraper conveyor 8. An ash discharge valve 7 is also installed on the ash conveying pipe 5.

[0025] Specifically, after opening the ash discharge valve 7, the flue gas will enter the buried scraper conveyor 8 through the ash delivery pipe 5 and be transported to the granulation workshop. The ash is fed into the buried scraper conveyor 8 through the ash delivery pipe 5 and the ash discharge valve 7. In case of emergency, the slide valve 6 is opened, and the flue gas from the oxidizer can go to the buried scraper 9 from the reduction furnace to the granulation workshop. This allows sufficient time to repair the scraper from the oxidizer to the granulation workshop without affecting the normal production of the oxidizer.

[0026] Specifically, by setting up a submerged scraper conveyor 1 and two sets of ash feeding mechanisms, the submerged scraper conveyor 1 transports the flue dust from the ash discharge pipe 2 and the ash discharge pipe 3 to the next stage. In conjunction with the ash feeding pipe 5, the flue dust in the scraper conveyor 1 is fed downward into the submerged scraper conveyor 2 8. Compared with the existing technology, when one of the submerged scraper conveyors 2 8 fails, there is no need to stop the machine. Just close the gate valve 6 on the faulty side and close the ash discharge valve 7 to stop ash discharge. Then open the gate valve 6 on the ash feeding pipe 5 on the other side and open the ash discharge valve 7 on that side to transport the flue dust in the submerged scraper conveyor 1. This avoids affecting the operation of the entire production line, prevents production efficiency from being affected, ensures output, and effectively improves practicality.

[0027] The bottom of the buried scraper conveyor 1 is equipped with a support frame 9, the bottom of the buried scraper conveyor 2 is equipped with a support frame 10, the bottom of the support frame 2 is equipped with a moving wheel 11, and a distance adjustment mechanism 12 is provided between adjacent support frames 2 10.

[0028] Furthermore, the distance adjustment mechanism 12 includes a connecting arm 121 connected to a support frame 2 10 on one side. The connecting arm 121 is connected to the support frame 2 10 by fasteners. A connecting arm 2 122 is connected to the support frame 2 10 on the other side by fasteners. The connecting arm 121 and the connecting arm 2 122 are movably connected.

[0029] Furthermore, a limiting post 123 is vertically fixed at the end of the connecting arm 2 122, and a moving groove 124 adapted to the limiting post 123 is provided along the length direction of the connecting arm 1 121. The width of the moving groove 124 is the same as the diameter of the limiting post 123. The end of the limiting post 123 extends upward through the moving groove 124 and is locked to the connecting arm 1 121 by a nut 125.

[0030] Specifically, by setting the moving wheel 11 and the distance adjustment mechanism 12, the position of the ash feeding pipe 5 is different for different production lines. The moving wheel 11 is used to adjust the distance between the connecting arm 121 and the connecting arm 222. Then, the nut 125 is used to lock the limiting post 123 and the connecting arm 121, so that the connecting arm 121 and the connecting arm 222 are locked to each other, thus achieving the purpose of distance adjustment.

[0031] The support frame 2 10 is equipped with a dwelling component 13 at its bottom;

[0032] Furthermore, the dwelling assembly 13 includes an L-shaped dwelling plate 131, with movable rods 133 fixed at the top of both ends of the dwelling plate 131, and the top of the movable rods 133 being movably connected to the support frame 10.

[0033] Furthermore, the top of the moving rod 133 is connected to a ball bearing seat 134, and a ball bearing 135 is installed inside the ball bearing seat 134. The support frame 10 has a rolling groove 136 that mates with the ball bearing 135; the rolling groove 136 is shaped like a "7". Figure 3 As shown, by moving the moving rod 133 along the rolling groove 136 to the leftmost end, the stationary plate 131 is separated from the ground and is in a moving state. By moving the moving rod 133 along the rolling groove 136 to the rightmost end, the stationary plate 131 is in contact with the ground and is in a stationary state.

[0034] Furthermore, a rubber block 132 is connected to the bottom of the dwell plate 131. The rubber block 132 can not only increase friction, but also reduce wear and extend service life by utilizing the wear-resistant properties of rubber.

[0035] Specifically, by setting up the dwelling component 13, the position of the moving rod 133 is adjusted up and down along the rolling groove 136, which drives the dwelling plate 131 to move up and down. When the dwelling plate 131 is at the same height as the moving wheel 11, the dwelling plate 131 abuts against the ground, increasing the contact area with the ground, thereby increasing the friction, preventing the support frame 2 10 from sliding under the drive of the moving wheel 11, and improving the stability of the buried scraper conveyor 2 8.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
