Technical Field

[0001] The utility model relates to the technical field of high-precision gas flow distribution plates, and particularly relates to a high-precision gas flow distribution plate. Background Art

[0002] According to a tube-type gas distributor and a gas-solid fluidized reactor disclosed in Chinese Patent Publication No. CN114432973A, the tube-type gas distributor includes: a main pipe and a plurality of branch pipes connected to the main pipe. A main pipe air inlet is provided on the main pipe, a plurality of air distribution holes are provided on the branch pipes, and a flow discharge hole is provided in the tail region of the branch pipes. During the use of this tube-type gas distributor, the initial design effect of the tube-type gas distributor is not reduced, blockage will not occur, and the actual use effect will not be damaged to varying degrees with the increase of the use time.

[0003] When the above-mentioned technology is used, only a fixed amount of gas can pass through, and the gas passing amount cannot be changed according to the amount of liquid. In this way, when the amount of liquid inside the tank is too small, the gas distributor that can only pass a fixed amount of gas in the above-mentioned technology will cause waste. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the gas passing amount cannot be changed according to the amount of liquid in the prior art, and a high-precision gas flow distribution plate is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a high-precision gas flow distribution plate includes a primary air pipe. Two secondary air pipes are provided on both sides of the primary air pipe. Two flanges are provided between the two secondary air pipes and the primary air pipe. An air inlet pipe is provided on the bottom surface of the primary air pipe. A flange is provided on the bottom surface of the air inlet pipe. Installation grooves are provided on the surfaces of the five flanges. Two clamping blocks are provided inside each of the two secondary air pipes, and four clamping blocks are provided inside the primary air pipe. Two damping blocks are provided inside the primary air pipe. Return springs are provided inside each of the two secondary air pipes. Sealing gaskets are provided on both sides of the primary air pipe. Six tertiary air pipes are provided on the surfaces of the primary air pipe and the two secondary air pipes. Two air caps are provided inside the primary air pipe. Card slots are provided on the surfaces of the two air caps. A filter screen is provided at the bottom of the air inlet pipe.

[0006] Preferably, the two flanges are welded to both ends of the primary air pipe. The two flanges are both welded to one end of the two secondary air pipes close to the primary air pipe. The flange is welded to the bottom surface of the air inlet pipe.

[0007] Preferably, the two secondary air pipes are connected to the primary air pipe through flanges. The two sealing gaskets are both installed in the installation grooves on the surfaces of the flanges of the two secondary air pipes and the primary air pipe.

[0008] Preferably, both of the said clamping blocks are provided on the bottom surface and the top surface inside the secondary air pipe. The four said clamping blocks are evenly provided at both ends of the primary air pipe in groups of two, one on top of the other. The positions of the clamping blocks installed inside the primary air pipe and the two secondary air pipes are the same.

[0009] Preferably, the two said clamping grooves are provided at the bottom end and the top end of the air cap, and the two clamping grooves of the air cap are both installed on the clamping block 6 of the primary air pipe.

[0010] Preferably, the two said damping blocks are evenly provided on both sides of the intake pipe, and the damping blocks are welded to the inner surface of the primary air pipe.

[0011] Preferably, the filter screen is installed in the installation groove of the bottom flange of the intake pipe.

[0012] Beneficial effects

[0013] In the present utility model, two secondary air pipes are connected to the primary air pipe through flanges. A return spring is provided inside the two secondary air pipes. The two air caps are installed on the clamping blocks inside the primary air pipe through clamping grooves. Two damping blocks are welded inside the primary air pipe. The damping blocks are provided on the side of the air cap away from the return spring. One end of the return spring abuts against the end of the secondary air pipe, and the other end of the return spring abuts against the air cap. When in use, gas enters the primary air pipe through the intake pipe. Since the air cap blocks the gas from the tertiary air pipe at the middle position of the primary air pipe to other tertiary air pipes, the gas entering the primary air pipe will then be aerated through the tertiary air pipes on the surface of the primary air pipe and mixed with the liquid for gas-liquid mixing. When the liquid is too much, the air pressure entering the primary air pipe through the intake pipe can be increased. The excessive air pressure will squeeze the air caps at both ends inside the primary air pipe, causing the air caps to move along the direction of the clamping blocks to both sides. When the air caps move and expose the other tertiary air pipes, the other tertiary air pipes can be ventilated. When the liquid is too little, the air pressure entering the primary air pipe inside the intake pipe can be reduced, causing the air caps to return to their original positions through the return springs. During the reset process, the two damping blocks inside the primary air pipe will block the air caps to prevent the air cap at one end from entering the secondary air pipe at the other end, solving the drawback that the gas throughput cannot be changed according to the amount of liquid.

[0024] The specific embodiments of the present utility model will be described below with reference to the attached drawings. Specific embodiment one:

[0026] Refer to Figures 1-7, a high-precision gas flow distribution plate, comprising a primary gas pipe 1. Secondary gas pipes 2 are provided on both sides of the primary gas pipe 1. Two flanges 3 are provided between the two secondary gas pipes 2 and the primary gas pipe 1. An intake pipe 7 is provided on the bottom surface of the primary gas pipe 1. A flange 3 is provided on the bottom surface of the intake pipe 7. Mounting grooves 12 are provided on the surfaces of the five flanges 3. Two clamping blocks 6 are provided inside each of the two secondary gas pipes 2, and four clamping blocks 6 are provided inside the primary gas pipe 1. Two damping blocks 10 are provided inside the primary gas pipe 1. Return springs 13 are provided inside each of the two secondary gas pipes 2. Sealing gaskets 5 are provided on both sides of the primary gas pipe 1. Six tertiary gas pipes 4 are provided on the surfaces of the primary gas pipe 1 and the two secondary gas pipes 2. Two gas caps 9 are provided inside the primary gas pipe 1. Card slots 11 are provided on the surfaces of the two gas caps 9. A filter screen 8 is provided at the bottom of the intake pipe 7. The two flanges 3 are welded to both ends of the primary gas pipe 1. The two flanges 3 are both welded to one end of the two secondary gas pipes 2 close to the primary gas pipe 1. The flange 3 is welded to the bottom surface of the intake pipe 7. The two secondary gas pipes 2 are connected to the primary gas pipe 1 through the flanges 3. The two sealing gaskets 5 are both installed in the mounting grooves 12 on the surfaces of the flanges 3 of the two secondary gas pipes 2 and the primary gas pipe 1. The two clamping blocks 6 are both provided on the bottom and top surfaces inside the secondary gas pipes 2. The four clamping blocks 6 are evenly provided in two groups, one above the other, at both ends of the primary gas pipe 1. The positions of the clamping blocks 6 installed inside the primary gas pipe 1 and the two secondary gas pipes 2 are the same. The two card slots 11 are provided at the bottom and top ends of the gas caps 9, and the two card slots 11 of the gas caps 9 are both installed on the clamping blocks 6 of the primary gas pipe 1. The two damping blocks 10 are evenly provided on both sides of the intake pipe 7, and the damping blocks 10 are welded to the inner surface of the primary gas pipe 1. The filter screen 8 is installed in the mounting groove 12 of the flange 3 on the bottom surface of the intake pipe 7.

[0027] On both the left and right sides of the primary air pipe 1, secondary air pipes 2 are provided. At both the left and right ends of the primary air pipe 1, flanges 3 are welded. At one end of each of the two secondary air pipes 2 close to the primary air pipe 1, a flange 3 is welded. The two secondary air pipes 2 are connected to the primary air pipe 1 through the flanges 3. At the bottom surface in the middle of the primary air pipe 1, an intake pipe 7 is provided, and a flange 3 is welded to the bottom surface of the intake pipe 7. Installation grooves 12 are provided on the surfaces of all five flanges 3. And in the installation grooves 12 at the connection points of the two secondary air pipes 2 and the flanges 3 at both ends of the primary air pipe 1, gaskets 5 are provided. The gaskets 5 will play a sealing role when the gas inside the primary air pipe 1 leads to the secondary air pipes 2 at both ends. And on the inner surface of the gasket 5, two clamping blocks 6 are also provided to prevent gas from leaking out through the connection points of the two flanges 3 when the gas flows inside the primary air pipe 1 and the secondary air pipes 2. Inside the two secondary air pipes 2, return springs 13 are provided. The return springs 13 will reset the air caps 9 inside the primary air pipe 1. And the two air caps 9 are installed on the clamping blocks 6 inside the primary air pipe 1 through the card slots 11 at the top and bottom of the surface. The clamping blocks 6 inside the primary air pipe 1 and the secondary air pipes 2 will limit the positions of the air caps 9 to prevent the air caps 9 from collapsing to both sides under the push of the gas or the return springs 13 when the air caps 9 move. The air caps 9 are arranged on both the left and right sides of the intake pipe 7. Inside the primary air pipe 1, two damping blocks 10 are welded. The two damping blocks 10 are arranged on the side of the air caps 9 away from the return springs 13. One end of the return spring 13 abuts against the end of the secondary air pipe 2, and the other end of the return spring 13 abuts against the air cap 9. During use, the air pressure entering the primary air pipe 1 through the intake pipe 7 can be controlled according to the liquid inside the tank body. When the liquid inside the tank body is too little, gas enters the primary air pipe 1 through the intake pipe 7. Since the two air caps 9 inside the primary air pipe 1 will block the gas leading to the tertiary air pipe 4 except for the position in the middle of the primary air pipe 1, the gas entering the primary air pipe 1 at this time will be blocked by the air caps 9 inside the primary air pipe 1 from leading to the secondary air pipes 2 on both sides, so that the gas can only pass through the tertiary air pipe 4 in the middle of the surface of the primary air pipe 1 for aeration and gas-liquid mixing with the liquid, reducing the gas passing through the other tertiary air pipes 4 and carrying out gas-liquid exchange with the liquid inside the tank body through the other tertiary air pipes 4, thereby reducing waste. The tertiary air pipe 4 is welded to the surfaces of the primary air pipe 1 and the secondary air pipes 2, and the tertiary air pipe 4 communicates with the primary air pipe 1 and the secondary air pipes 2. On both sides of the surfaces of the two secondary air pipes 2 and the primary air pipe 1, tertiary air pipes 4 are provided. When the liquid is too much, the air pressure entering the primary air pipe 1 through the intake pipe 7 can be increased. The excessive air pressure will squeeze the air caps 9 at both ends inside the primary air pipe 1, causing the air caps 9 to move along the direction of the clamping blocks 6 to both sides. When the air caps 9 move, the other tertiary air pipes 4 blocked by the air caps 9 will be gradually exposed. At this time, the other tertiary air pipes 4 can be ventilated, and gas enters the other tertiary air pipes 4 to carry out gas-liquid exchange with the liquid inside the tank body, thereby improving the exchange efficiency to cope with the excessive liquid inside the tank body.When the liquid gradually decreases, the air pressure entering the interior of the primary air pipe 1 through the air inlet pipe 7 can be reduced, causing the air cap 9 to return to its original position through the return spring 13. During the return process, the two damping blocks 10 inside the primary air pipe 1 will block the air cap 9 to prevent the air cap 9 at one end from entering the secondary air pipe 2 at the other end. Inside the air inlet pipe 7, the filter screen 8 will block the particles in the gas to prevent the particles from blocking the air holes on the surface of the tertiary air pipe 4.

[0028] When the gas flow distributor is in use, gas enters the interior of the primary air pipe 1 from the air inlet pipe 7 and evenly flows to the secondary air pipes 2 on both sides of the primary air pipe 1. The gas flowing into the primary air pipe 1 and the secondary air pipes 2 evenly flows to the tertiary air pipes 4 that communicate with the primary air pipe 1 and the secondary air pipes 2, and the gas is transported into the tank interior through the through holes on the surface of the tertiary air pipe 4, thereby achieving the effect of uniform gas distribution. Specific Embodiment Two:

[0030] Refer to Figures 1-7 , for a high-precision gas flow distribution plate, further based on the basic structure in Specific Embodiment One, a connecting pipe can be added between the surfaces of the primary air pipe 1 and the two secondary air pipes 2 and the middle of the tertiary air pipe 4. The connecting pipe is welded to the surfaces of the primary air pipe 1 and the secondary air pipes 2, and a flange 3 is provided at one end of the connecting pipe close to the tertiary air pipe 4. A flange 3 is provided at one end of the tertiary air pipe 4 close to the connecting pipe. The tertiary air pipe 4 is connected to the connecting pipe through the flange 3. In this way, when the tertiary air pipe 4 is damaged, the fixing bolts of the corresponding flange 3 of the damaged tertiary air pipe 4 can be removed to separate the damaged tertiary air pipe 4 from the connecting pipe. At this time, a new tertiary air pipe 4 can be installed on the original damaged connecting pipe through the flange 3. In this way, when the tertiary air pipe 4 is damaged, it is not necessary to replace the entire secondary air pipe 2 and the primary air pipe 1, greatly reducing the replacement cost.

[0031] In summary:

[0032] 1. Two secondary air pipes 2 are connected to the primary air pipe 1 through flanges 3. A return spring 13 is arranged inside the two secondary air pipes 2. And two air caps 9 are installed on the clamping blocks 6 inside the primary air pipe 1 through clamping grooves 11. Two damping blocks 10 are welded inside the primary air pipe 1. The damping blocks 10 are arranged on the side of the air cap 9 away from the return spring 13. One end of the return spring 13 abuts against the end of the secondary air pipe 2, and the other end of the return spring 13 abuts against the air cap 9. When in use, gas enters the primary air pipe 1 through the inlet pipe 7. Since the air cap 9 blocks the gas from other tertiary air pipes 4 except the tertiary air pipe 4 at the middle position of the primary air pipe 1, the gas entering the inside of the primary air pipe 1 will pass through the tertiary air pipes 4 on the surface of the primary air pipe 1 for aeration and perform gas-liquid mixing with the liquid. When the liquid is too much, the air pressure entering the primary air pipe 1 through the inlet pipe 7 can be increased. The excessive air pressure will squeeze the air caps 9 at both ends inside the primary air pipe 1, causing the air caps 9 to move along the direction of the clamping blocks 6 to both sides. When the air caps 9 move and expose the other tertiary air pipes 4, the other tertiary air pipes 4 can be ventilated. When the liquid is too little, the air pressure entering the inside of the primary air pipe 1 through the inlet pipe 7 can be reduced, so that the air caps 9 return to their original positions through the return springs 13. During the reset process, the two damping blocks 10 inside the primary air pipe 1 will block the air caps 9 to prevent the air cap 9 at one end from entering the secondary air pipe 2 at the other end, solving the defect that the gas passage amount cannot be changed according to the amount of liquid.
