Description

Technical Field

[0001] This utility model relates to the field of flue gas denitrification catalyst technology, and in particular to a flue gas denitrification catalyst regeneration device. Background Technology

[0002] Flue gas denitrification catalysts are structures used to purify flue gas. In the flue gas treatment process of thermal power plants, the large-scale combustion of fossil fuels such as coal produces flue gas containing high concentrations of nitrogen oxides. Using flue gas denitrification catalysts can effectively reduce the emission of these harmful gases, reduce pollution to the atmospheric environment, and play a vital role in environmental protection.

[0003] A flue gas denitrification catalyst regeneration and cleaning device, disclosed in CN212999343U, includes a circular block, an inner cavity, and a side groove. The inner cavity is located within the circular block, and the side groove is located on the side surface of the circular block. A cleaning structure is provided on the circular block. The cleaning structure mainly includes a movable plate, a driving part, and a dust suction part. The movable plate is connected to the side groove and the inner cavity through the driving part. The dust suction part is located on the movable plate and the circular block. This invention directly inserts the cleaning part into the denitrification catalyst and cleans the dust by repeatedly inserting and removing it, thus avoiding damage to the denitrification catalyst.

[0004] Existing technologies often have the following drawbacks: After using a honeycomb structure flue gas denitrification catalyst, the catalyst can often be regenerated by cleaning. However, after cleaning the honeycomb structure flue gas denitrification catalyst with a brush, the bristles on the brush tend to stick to dust and become messy, thus reducing the subsequent cleaning and regeneration effect of the flue gas denitrification catalyst.

[0005] Therefore, this utility model provides a flue gas denitrification catalyst regeneration device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where brush bristles on the brush handle tend to easily attract dust and become messy, and to propose a flue gas denitrification catalyst regeneration device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a flue gas denitrification catalyst regeneration device, comprising an installation ring, a servo motor fixedly installed on the inner side of the installation ring, an installation rod fixedly installed on the side wall of the installation ring, an installation plate fixedly installed at the other end of the installation rod, a first gear fixedly installed through the output end of the servo motor via the installation plate, a brush rod rotatably installed inside the installation plate, a second gear fixedly installed on the side wall of the brush rod, a rack slidably connected inside the installation plate, the tooth surface of the rack meshing with the first gear and the second gear, a combing structure provided on the surface of the installation plate, the combing structure comprising a support rod fixedly installed on the surface of the installation plate, a rotating rod rotatably installed inside the support rod, and a plurality of comb plates uniformly fixedly connected to the side wall of the rotating rod.

[0008] The effect achieved by the above-mentioned components is that by setting up a combing structure, it is convenient to flexibly comb the bristles on the side wall of the brush bar, which to a certain extent improves the cleaning efficiency of the honeycomb structure flue gas denitrification catalyst when using the brush bar.

[0009] Preferably, a rectangular block is fixedly connected to the side wall of the support rod, and a retaining frame is slidably connected inside the rectangular block. A retaining groove is opened on the side wall of the rotating rod, and the size of the retaining groove is adapted to the size of the retaining frame.

[0010] The effect achieved by the above components is that the card frame can be inserted into the inside of the card slot to lock the rotating rod after it is twisted.

[0011] Preferably, a spring is fixedly installed between the card frame and the rectangular block.

[0012] The effect achieved by the above components is that the card frame will be inserted into the inside of the card slot by the elastic force of the spring on the rectangular block.

[0013] Preferably, an auxiliary head is fixedly installed on the end side of the card frame, and the auxiliary head is a ladder structure.

[0014] The effect achieved by the above components is that the auxiliary head of the ladder structure improves the efficiency of inserting the card frame into the card slot.

[0015] Preferably, the mounting ring has an internal support structure, the support structure including a support frame slidably mounted inside the mounting ring, and the mounting ring has bolts threadedly connected to its interior.

[0016] The effect achieved by the above components is as follows: by setting up a support structure and adjusting the height of the servo motor twice, the cleaning of the flue gas denitrification catalyst at different height positions is facilitated, and the efficiency of cleaning the flue gas denitrification catalyst is further improved.

[0017] Preferably, the side wall of the support frame is provided with an insertion hole, the size of which is adapted to the size of the bolt.

[0018] The effect achieved by the above components is that inserting the bolts into the inner side of the corresponding sockets improves the stability of fixing the adjusted servo motor.

[0019] Preferably, the support frame has two sliding links inside, and the lower ends of the two sliding links are fixedly mounted with mounting bases.

[0020] The effect achieved by the above components is that the slider restricts the direction of movement of the mounting base.

[0021] Preferably, the support frame is internally threaded with a drive rod, and the drive rod is internally rotatably connected to the mounting base.

[0022] The effect achieved by the above components is that rotating the drive rod will cause relative movement between the mounting base and the support frame.

[0023] In summary:

[0024] 1. In this utility model, the first gear drives the rack, thereby enabling the simultaneous driving of multiple second gears. The second gears drive the relative movement between the brush rod and the comb plate, thus enabling the combing of messy bristles and the cleaning of mud and ash adhering to the bristles. After cleaning, the rotating rod can be flipped and retracted to the side perpendicular to the brush rod, enabling normal use of the brush rod. By setting the combing structure, the flexible combing of the bristles on the side wall of the brush rod is facilitated, which to a certain extent improves the cleaning efficiency of the honeycomb structure flue gas denitrification catalyst after the brush rod is used.

[0025] 2. In this utility model, rotating the drive rod will cause relative movement between the mounting base and the support frame, which facilitates the fine adjustment of the servo motor support height. By setting up the support structure and adjusting the servo motor height twice, it is convenient to clean the flue gas denitrification catalyst at different height positions, further improving the efficiency of cleaning the flue gas denitrification catalyst.

[0032] Reference Figure 1 As shown, this utility model provides a technical solution: a flue gas denitrification catalyst regeneration device, including an installation ring 1, a servo motor 2 fixedly installed on the inner side of the installation ring 1, an installation rod 3 fixedly installed on the side wall of the installation ring 1, an installation plate 4 fixedly installed on the other end of the installation rod 3, a first gear 5 fixedly installed through the output end of the servo motor 2 through the installation plate 4, a brush rod 10 rotatably installed inside the installation plate 4, a second gear 9 fixedly installed on the side wall of the brush rod 10, a rack 6 slidably connected inside the installation plate 4, the tooth surface of the rack 6 meshing with the first gear 5 and the second gear 9, a combing structure 7 provided on the surface of the installation plate 4, and a support structure 8 provided inside the installation ring 1.

[0033] The following section will explain the specific setup and function of its sorting structure 7 and support structure 8.

[0034] Reference Figures 1-3 As shown in this embodiment: the combing structure 7 includes a support rod 71 fixedly installed on the surface of the mounting plate 4. A rotating rod 72 is rotatably installed inside the support rod 71, and several comb plates 73 are uniformly fixedly connected to the side wall of the rotating rod 72. By setting the combing structure 7, the flexible combing of the bristles on the side wall of the brush rod 10 is facilitated, which to a certain extent improves the cleaning efficiency of the honeycomb structure flue gas denitrification catalyst using the brush rod 10. A rectangular block 75 is fixedly connected to the side wall of the support rod 71. A retaining frame 76 is slidably connected inside the rectangular block 75. A retaining groove 74 is opened on the side wall of the rotating rod 72. The size of the retaining groove 74 is adapted to the size of the retaining frame 76. The retaining frame 76 is inserted into the inside of the retaining groove 74 to realize the locking operation of the rotating rod 72 after twisting. A spring 77 is fixedly installed between the retaining frame 76 and the rectangular block 75. The retaining frame 76 is inserted into the inside of the retaining groove 74 by the elastic force of the spring 77 on the rectangular block 75. An auxiliary head 78, which has a trapezoidal structure, is fixedly installed on one end of the card frame 76. The trapezoidal structure of the auxiliary head 78 improves the efficiency of inserting the card frame 76 into the card slot 74.

[0035] Reference Figure 1 and Figures 4-5 As shown, specifically, the support structure 8 includes a support frame 81 slidably mounted inside the mounting ring 1, with bolts 86 threadedly connected to the inside of the mounting ring 1. By setting up the support structure 8, the cleaning of the flue gas denitrification catalyst at different height positions is facilitated through two adjustments to the height of the servo motor 2, further improving the efficiency of cleaning the flue gas denitrification catalyst. The side wall of the support frame 81 has insertion holes 85, the size of which matches the size of the bolts 86. Inserting the bolts 86 into the corresponding insertion holes 85 improves the stability of fixing the adjusted servo motor 2. Two sliding strips 84 are slidably connected inside the support frame 81, and mounting seats 82 are fixedly mounted at the lower ends of the two sliding strips 84. The sliding strips 84 limit the movement direction of the mounting seats 82. A drive rod 83 is threadedly connected inside the support frame 81, and the drive rod 83 is rotatably connected to the mounting seat 82. Rotating the drive rod 83 causes relative movement between the mounting seat 82 and the support frame 81.

[0036] Working principle: When it is necessary to comb the bristles on the brush rod 10, the retaining frame 76 can be pulled out, and the rotating rod 72 inside the support rod 71 can be rotated. When the comb plate 73 is rotated to the position against the side wall of the brush rod 10, the retaining frame 76 is released. At this time, the retaining frame 76 will be inserted into the inner side of the retaining slot 74 by the elastic force of the spring 77 on the rectangular block 75. The auxiliary head 78 with the trapezoidal structure improves the efficiency of the retaining frame 76 being inserted into the inner side of the retaining slot 74. At this time, the locking operation of the rotated rod 72 after rotation can be realized. At this time, the servo motor 2 is started, and the servo motor 2 will drive the first gear 5 to rotate. The first gear 5 will drive the gear... The drive bar 6 enables the simultaneous operation of multiple second gears 9. The second gears 9 drive the relative movement between the brush rod 10 and the comb plate 73, thereby combing the messy bristles and cleaning the mud and ash adhering to the bristles. After cleaning, the rotating rod 72 can be flipped and retracted to the side perpendicular to the brush rod 10, allowing the brush rod 10 to be used normally. By setting the combing structure 7, the flexible combing of the bristles on the side wall of the brush rod 10 is facilitated, which to a certain extent improves the cleaning efficiency of the honeycomb structure flue gas denitrification catalyst after the brush rod 10 is used.

[0037] When it is necessary to clean the flue gas denitrification catalysts at different heights in rows, the mounting base 82 can be placed on the ground. By sliding the support frame 81 inside the mounting ring 1, the height of the servo motor 2 can be quickly adjusted. At this time, rotating the bolt 86 and inserting it into the inner side of the corresponding socket 85 improves the stability of fixing the adjusted servo motor 2. Then, rotating the drive rod 83 will push the mounting base 82 and the support frame 81 to move relative to each other, which facilitates the fine adjustment of the support height of the servo motor 2. By setting up the support structure 8 and adjusting the height of the servo motor 2 twice, the cleaning of the flue gas denitrification catalysts at different heights is facilitated, further improving the efficiency of cleaning the flue gas denitrification catalysts.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
