Description

Technical Field

[0001] This utility model relates to the field of uniform distribution plate technology, specifically a uniform distribution plate with a wind cap structure for flue gas treatment. Background Technology

[0002] With the acceleration of industrialization and increasingly stringent environmental protection requirements, flue gas treatment technology has become a key link in industrial emission control. Among various flue gas treatment devices, reactors are widely used in flue gas desulfurization, denitrification, and dust removal due to their high gas-solid contact efficiency. One of the core components ensuring the normal operation of a fluidized bed is the air distribution plate (also known as an air distribution plate). As a key device for airflow distribution, the performance of the air distribution plate directly affects the efficiency, energy consumption, and stability of the entire flue gas treatment system. The working principle of the air distribution plate is based on the physical characteristics of airflow bending multiple times. When the airflow passes through the air distribution plate, it first moves vertically upward, then passes through the bending of the air cap structure, and is then horizontally ejected from the side holes or side seams of the air cap. In the case of material stacking, these horizontally ejected airflows form an air cushion layer between the air cap and the plate, uniformly supporting the material layer, thereby achieving uniform fluidization of solid particles.

[0003] When using a uniform distribution plate, the wind cap is usually fixed to the plate by thread or welding. If threaded connection is used, the wind cap may loosen due to the influence of high-intensity airflow, and the stability of the installation needs to be improved. If welding is used, the wind cap installation is more complicated, requiring the use of a welding gun, which is inefficient. In addition, the wind cap is not easy to disassemble, making maintenance very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a uniformly distributed plate with a wind cap structure for flue gas treatment, which improves the stability of wind cap installation, is simple and convenient to operate, enables quick disassembly and replacement of wind cap, facilitates maintenance, and has high efficiency, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniformly distributed plate with a wind cap structure for flue gas treatment, comprising a plate body and airflow channels uniformly arranged on the plate body, wind caps connected to the airflow channels, the wind caps comprising a cap head and a cap rod connected to the bottom of the cap head, the cap rod being inserted into the airflow channels, connecting ports uniformly connected on the plate body, the connecting ports being aligned with the corresponding airflow channels, and L-shaped grooves provided on the connecting ports, two sliding blocks connected to the outer side of the cap rod, the sliding blocks being connected to the L-shaped grooves, and the sliding blocks being connected to a positioning mechanism for positioning the sliding blocks.

[0006] Preferably, the cap rod is provided with multiple exhaust holes, which are connected to the airflow channel.

[0007] Preferably, the L-shaped groove includes a guide groove and a connecting groove, the guide groove and the connecting groove are connected, and the guide groove and the connecting groove are disposed at the connection port, and the sliding block is matched with the guide groove and the connecting groove.

[0008] Preferably, an inclined block is connected in the connecting groove, and the inclined block presses against the sliding block.

[0009] Preferably, the positioning mechanism includes a positioning rod, a guide block, a spring, and a sliding groove. The guide block is used to guide the positioning rod and matches the sliding groove. The spring is used to drive the positioning rod to move in the direction of the sliding block. The positioning rod is connected to the sliding block.

[0010] Preferably, the slide groove is disposed within the connection port, the guide block is slidably connected to the slide groove, and the guide block is fixedly connected to the positioning rod.

[0011] Preferably, the spring is located inside the groove and is sleeved on the positioning rod, with both ends of the spring connected to the guide block and the connection port.

[0012] Preferably, the top of the sliding block is provided with a limiting groove, and the positioning rod is connected to the limiting groove.

[0013] Preferably, a sealing surface is connected inside the airflow channel, and the sealing surface is connected to the cap rod.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention, by incorporating a positioning mechanism, connects the cap rod to the airflow channel on the plate. The sliding block slides relative to the guide groove, and rotating the cap rod synchronously drives the two sliding blocks to rotate, causing them to insert into the connecting groove. The positioning mechanism then limits the sliding blocks, thus fixing the cap rod and improving the stability of the wind cap installation. Operation is simple and convenient. When the wind cap needs to be disassembled, pulling the positioning rod upwards separates it from the sliding block. Then, rotating the wind cap causes the sliding block to move out of the guide groove, enabling quick disassembly and replacement of the wind cap with high efficiency. 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] Please see Figures 1 to 5 This utility model provides a uniformly distributed plate with a wind cap structure for flue gas treatment, including a plate body 1 and airflow channels 8 uniformly arranged on the plate body 1. Wind caps are connected to the airflow channels 8, and the wind caps include a cap head 2 and a cap rod 3 connected to the bottom of the cap head 2. The cap rod 3 is inserted into the airflow channel 8. Connection ports 4 are uniformly connected on the plate body 1, and the connection ports 4 are aligned with the corresponding airflow channels 8. The connection ports 4 are provided with L-shaped grooves. Two sliding blocks 11 are connected to the outer side of the cap rod 3. The sliding blocks 11 are connected to the L-shaped grooves, and the sliding blocks 11 are connected to a positioning mechanism for positioning the sliding blocks 11.

[0025] When installing the wind cap, align the two sliding blocks 11 on the outer side of the cap rod 3 with the guide groove 6, then insert the cap rod 3 into the airflow channel 8, and the sliding blocks 11 slide within the guide groove 6. Then rotate the wind cap, simultaneously rotating the two sliding blocks 11, causing them to screw into the connecting groove 10. A positioning mechanism then limits the sliding blocks 11, improving the stability of the wind cap installation. The operation is simple and convenient.

[0026] The cap rod 3 is provided with multiple exhaust holes 7, which are connected to the airflow channel 8. Gas enters into the cap rod 3 through the airflow channel 8 and then exits through the exhaust holes 7. The airflow forms an air cushion layer between the cap and the plate 1, which evenly lifts the material layer, thereby achieving uniform fluidization of solid particles.

[0027] The L-shaped groove includes a guide groove 6 and a connecting groove 10. The guide groove 6 and the connecting groove 10 are connected and are located at the connection port 4. The sliding block 11 is matched with the guide groove 6 and the connecting groove 10.

[0028] An inclined block 12 is connected inside the connecting groove 10. The inclined block 12 applies downward pressure to the sliding block 11, thereby improving the stability of the cap 2 installation.

[0029] The positioning mechanism includes a positioning rod 5, a guide block 13, a spring 14, and a sliding groove. The guide block 13 guides the positioning rod 5 and matches the sliding groove. The spring 14 drives the positioning rod 5 to move towards the sliding block 11. The positioning rod 5 is connected to the sliding block 11. During the process of the sliding block 11 being screwed into the connecting groove 10, the inclined surface on the sliding block 11 slides relative to the bottom of the positioning rod 5, thereby lifting the positioning rod 5. At this time, the spring 14 is stretched until the sliding block 11 presses against the guide block 13, at which point the sliding block 11 stops moving, and the bottom of the positioning rod 5 aligns with the limiting groove 15. The stretched spring 14 drives the positioning rod 5 back to its original position, so that the positioning rod 5 and the limiting groove 15 are connected, thereby limiting the sliding block 11 and improving the stability of the wind cap. This process does not require operation of the positioning rod 5, is simple and convenient, shortens the installation time, and is highly efficient.

[0030] Spring 14 is made of precipitation-hardening stainless steel, which has good elasticity and high temperature resistance, and a long service life. When the sliding block 11 is in the positioning state, spring 14 is slightly stretched or in the normal state to prevent the positioning rod 5 from disengaging from the limiting groove 15.

[0031] A slide groove is provided within the connection port 4, and a guide block 13 is slidably connected to the slide groove, while the guide block 13 is fixedly connected to the positioning rod 5. When the positioning rod 5 is raised or lowered, the guide block 13 slides within the slide groove, providing good guidance for the positioning rod 5 and improving the stability of the raising and lowering of the positioning rod 5.

[0032] The top of the limiting groove 15 is rounded to facilitate the connection between the positioning rod 5 and the limiting groove 15.

[0033] Spring 14 is located in the groove and is sleeved on the positioning rod 5. Both ends of spring 14 are connected to guide block 13 and connection port 4.

[0034] The top of the sliding block 11 is provided with a limiting groove 15, and the positioning rod 5 is connected to the limiting groove 15.

[0035] A sealing surface 9 is connected inside the airflow channel 8. The sealing surface 9 is connected to the cap rod 3. The setting of the sealing surface 9 improves the sealing performance between the cap rod 3 and the airflow channel 8, that is, the wind cap is tightly connected to the plate 1.

[0036] Working principle: In use, insert the cap rod 3 into the airflow channel 8 of the plate 1, causing the sliding block 11 to slide relative to the guide groove 6. Then rotate the wind cap in the following direction: Figure 2 The arrow points to the center, simultaneously rotating the two sliding blocks 11, causing them to gradually slide into the connecting groove 10. The inclined surface of the sliding block 11 slides relative to the bottom of the positioning rod 5, lifting the positioning rod 5 and simultaneously causing the guide block 13 to rise. The spring 14 is stretched until the sliding block 11 is pressed against the inclined block 12, at which point the hood stops rotating. The stretched spring 14 pulls the guide block 13 and the positioning rod 5 back to their original positions, causing the bottom of the positioning rod 5 to insert into the limiting groove 15, thereby limiting the sliding block 11 and improving the stability of the connection between the hood and the plate 1. When the hood needs to be disassembled and replaced, the positioning rod 5 is pulled upwards to separate it from the limiting groove 15. Then, the hood is rotated to move the sliding block 11 out of the connecting groove 10, and the hood is lifted to separate the sliding block 11 from the guide groove 6. This allows for quick disassembly of the hood, facilitating maintenance and repair. The operation is simple, convenient, and efficient.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
