Description

Technical Field

[0001] This utility model relates to the technical field of feeding equipment, specifically a feeding device for flue gas desulfurization and denitrification. Background Technology

[0002] Flue gas desulfurization and denitrification technology is a boiler purification technology applied in the chemical industry, which generates nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are major sources of air pollution, so this technology can effectively reduce air pollution. Flue gas desulfurization and denitrification technologies can be divided into three main categories: wet, semi-dry, and dry methods. Wet and semi-dry methods require large amounts of water, and the treatment of byproducts is relatively difficult. In the process of flue gas desulfurization and denitrification, some additives are needed. To save manpower, feeding equipment is used when adding additives to the flue gas desulfurization and denitrification equipment.

[0003] According to the Chinese Patent Publication No. CN221758714U, "A Feeding Device for Flue Gas Desulfurization and Denitrification," this invention solves the problem of existing feeding devices having fixed and non-adjustable feeding pipes. These devices utilize a combination of a flue gas treatment device, a feeding device body, an adjusting block, a discharge pipe, a rotating rod, a worm gear, a worm, and a handle. This addresses the issue that most existing feeding devices have fixed and non-adjustable feeding pipes, making it difficult to quickly align the discharge port of the feeding pipe with the feeding port of the flue gas desulfurization and denitrification equipment. This necessitates constant movement of the feeding device by operators to find the feeding port, causing inconvenience and affecting feeding efficiency. By incorporating a through hole, the rotating rod can pass through the adjusting block, facilitating its flexible rotation within the through hole. A bracket provides auxiliary support for the rotating rod and allows for smoother rotation. A limit ring limits the worm gear, preventing displacement due to wear during rotation.

[0004] However, the above-mentioned device has the problem that packaging bags and other debris often enter the hopper when feeding, and the additives tend to clump together. The feeding equipment can easily cause blockages when carrying the clumped additives. If workers have to clean the debris by hand, it is extremely dangerous. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for flue gas desulfurization and denitrification to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a feeding device for flue gas desulfurization and denitrification, including a feeding structure and a flue gas treatment device, wherein the flue gas treatment device is fixedly connected to the outer wall of the feeding structure;

[0007] The feeding structure includes a support frame, a hopper is fixedly connected to the top of the support frame, a feeding spiral tube is fixedly connected to the bottom of the hopper, a support platform is fixedly connected to the inner wall of the hopper, a guide rod is fixedly connected to the outer wall of the support platform, a return spring is sleeved on the outer surface of the guide rod, an installation frame is slidably connected to the outer surface of the guide rod, and a filter screen is snapped into the inside of the installation frame.

[0008] Preferably, a servo motor is fixedly connected to the outer wall of the hopper, a rotating shaft is fixedly connected to the output end of the servo motor, and an eccentric wheel is fixedly connected to the outer wall of the rotating shaft.

[0009] Preferably, the end of the rotating shaft away from the servo motor extends through the hopper into the interior and is rotatably connected to the hopper via a bearing, and the eccentric wheel is located below the mounting frame.

[0010] Preferably, the top of the reset spring is fixedly connected to the outer wall of the support platform, and the bottom of the reset spring is fixedly connected to the upper surface of the mounting frame.

[0011] Furthermore, when the mounting frame moves upward, it compresses the spring; when the mounting frame moves downward, it pulls the spring. The compression or pulling of the spring will cause the mounting frame to return to its original position.

[0012] Preferably, the inner walls on both sides of the mounting frame are provided with fixing grooves, and fixing blocks are provided inside the fixing grooves, with the top of the fixing blocks being semi-circular.

[0013] Preferably, a fixing spring is fixedly connected to the inner wall of the fixing groove, and the top of the fixing spring is fixedly connected to the bottom of the fixing block.

[0014] Preferably, the outer walls on both sides of the filter screen are provided with positioning grooves, and the shape and size of the positioning grooves are adapted to the shape and size of the fixing grooves.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model involves feeding additives into a hopper and pre-filtering them using a built-in filter screen to prevent packaging bags and other debris from entering the hopper and to prevent the additives from clogging the feed spiral tube. By starting a servo motor, the rotating shaft is driven to rotate, which in turn drives the eccentric wheel to rotate and contact the bottom of the mounting frame. The eccentric wheel presses against the mounting frame, causing the mounting frame to move up and down along the guide rod, while also moving the filter screen up and down. As the additives move up and down on the filter screen, they generate movement, making it easier for clumps of additives to disperse, accelerating the screening and filtration of additives, and making the feeding equipment more efficient and safe.

[0017] Secondly, this utility model involves pressing the filter screen into the installation frame. When the positioning groove on the filter screen aligns with the fixing groove in the installation frame, the fixing spring in the fixing groove applies an outward force to the fixing block, causing the fixing block to disengage from the fixing groove and engage with the positioning groove, thus completing the installation of the filter screen. After the additive is filtered, simply pull the filter screen outward to compress the fixing block, causing it to disengage from the positioning groove and retract into the fixing groove, thus completing the disassembly of the filter screen. This structure is simple, easy to assemble and disassemble, and convenient for workers to clean and replace the filter screen. Attached Figure Description

[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] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-4 A feeding device for flue gas desulfurization and denitrification includes a feeding structure 1 and a flue gas treatment device 2, wherein the flue gas treatment device 2 is fixedly connected to the outer wall of the feeding structure 1.

[0027] The feeding structure 1 includes a support frame 101, a hopper 102 fixedly connected to the top of the support frame 101, a feeding spiral tube 103 fixedly connected to the bottom of the hopper 102, a support platform 104 fixedly connected to the inner wall of the hopper 102, a guide rod 105 fixedly connected to the outer wall of the support platform 104, a reset spring 106 sleeved on the outer surface of the guide rod 105, and a mounting frame 107 slidably connected to the outer surface of the guide rod 105. A filter screen 108 is snapped into the inside of the mounting frame 107.

[0028] A servo motor 109 is fixedly connected to the outer wall of the hopper 102. A rotating shaft 110 is fixedly connected to the output end of the servo motor 109. An eccentric wheel 111 is fixedly connected to the outer wall of the rotating shaft 110.

[0029] The end of the rotating shaft 110 away from the servo motor 109 extends through the hopper 102 into the interior and is rotatably connected to the hopper 102 via a bearing. The eccentric wheel 111 is located below the mounting frame 107.

[0030] The top of the reset spring 106 is fixedly connected to the outer wall of the support platform 104, and the bottom of the reset spring 106 is fixedly connected to the upper surface of the mounting frame 107.

[0031] Through the above technical solution, the additive is put into the hopper 102 and filtered in advance by the filter screen 108 to prevent packaging bags and other debris from entering the hopper 102 and to prevent the additive from clogging the inside of the feed spiral tube 103. The servo motor 109 is started to drive the rotating shaft 110 to rotate, which also drives the eccentric wheel 111 to rotate and contact the bottom of the mounting frame 107. The eccentric wheel 111 squeezes the mounting frame 107, causing the mounting frame 107 to move up and down along the guide rod 105. At the same time, it also drives the filter screen 108 to move up and down. In this way, the additive moves when the filter screen 108 moves up and down, making it easier for the clumps of additive to disperse, speeding up the screening and filtration of the additive, and making the feeding equipment more efficient and safe.

[0032] Example 2

[0033] Please see Figure 1-4 Furthermore, based on Example 1, a feeding device for flue gas desulfurization and denitrification is obtained, comprising a feeding structure 1 and a flue gas treatment device 2, wherein the flue gas treatment device 2 is fixedly connected to the outer wall of the feeding structure 1.

[0034] The feeding structure 1 includes a support frame 101, a hopper 102 fixedly connected to the top of the support frame 101, a feeding spiral tube 103 fixedly connected to the bottom of the hopper 102, a support platform 104 fixedly connected to the inner wall of the hopper 102, a guide rod 105 fixedly connected to the top of the support platform 104, a reset spring 106 sleeved on the outer surface of the guide rod 105, a mounting frame 107 slidably connected to the outer surface of the guide rod 105, and a filter screen 108 snapped into the inside of the mounting frame 107.

[0035] The mounting frame 107 has fixing grooves 112 on both sides of its inner wall. Fixing blocks 113 are provided inside the fixing grooves 112, and the top of the fixing blocks 113 is semi-circular.

[0036] A fixing spring 114 is fixedly connected to the inner wall of the fixing groove 112, and the top of the fixing spring 114 is fixedly connected to the bottom of the fixing block 113.

[0037] The filter screen 108 has positioning grooves 115 on both outer walls, and the shape and size of the positioning grooves 115 are adapted to the shape and size of the fixing grooves 112.

[0038] With the above technical solution, by pressing the filter screen 108 into the mounting frame 107, when the positioning groove 115 on the filter screen 108 is aligned with the fixing groove 112 in the mounting frame 107, the fixing spring 114 in the fixing groove 112 applies an outward force to the fixing block 113, causing the fixing block 113 to disengage from the fixing groove 112 and engage with the positioning groove 115, thus completing the installation of the filter screen 108. After the additive is filtered, simply pull the filter screen 108 outward to compress the fixing block 113, causing it to disengage from the positioning groove 115 and retract into the fixing groove 112, thus completing the disassembly of the filter screen 108. This structure is simple, easy to assemble and disassemble, and convenient for workers to clean and replace the filter screen 108.

[0039] In use: First, the operator installs the filter screen 108 into the mounting frame 107, starts the servo motor 109 to drive the eccentric wheel 111 to rotate and drive the mounting frame 107 and the filter screen 108 to reciprocate. Then, the additive is poured into the hopper 102 and filtered through the filter screen 108. Finally, the filtered additive is fed into the flue gas treatment equipment 2 through the feed spiral pipe 103 for flue gas desulfurization and denitrification.
