Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A biomass boiler air chamber ash cleaning device comprises an air chamber pipeline body 1, a cleaning component 2 is arranged inside the air chamber pipeline body 1, and a storage component 3 is arranged below the air chamber pipeline body 1;

[0031] The cleaning component 2 includes a liquid storage tank 201, a hydraulic pump 202, a water outlet pipe 203 and an atomizing nozzle 204. The liquid storage tank 201 is arranged at the top of the air chamber pipe body 1, the hydraulic pump 202 is arranged at the inner top of the air chamber pipe body 1, the water outlet pipe 203 is bolted to the bottom output end of the air chamber pipe body 1, the atomizing nozzle 204 is arranged below the water outlet pipe 203, the input end of the hydraulic pump 202 is connected to the interior of the liquid storage tank 201, and the interior of the water outlet pipe 203 is connected to the output end of the hydraulic pump 202.

[0032] Specifically, Figure 2 As shown, the storage assembly 3 includes a feed pipe 301, a gathering bucket 302 and a storage barrel 303. The feed pipe 301 is arranged below the air chamber pipe body 1, the gathering bucket 302 is arranged below the feed pipe 301, and the storage barrel 303 is threadedly connected to the bottom of the gathering bucket 302.

[0033] Specifically, Figure 2 As shown, a fan 4 is disposed inside the air chamber pipe body 1 , and the fan 4 is located on one side of the water outlet pipe 203 .

[0034] Specifically, Figure 2 As shown, a filter plate 5 is disposed inside the air chamber pipe body 1 , and the filter plate 5 is located on the other side of the water outlet pipe 203 , and the filter plate 5 is located on the upper side of the feed pipe 301 .

[0035] Specifically, Figure 2 As shown, a blocking plate 6 is arranged on one side of the filter plate 5 , and the height of the blocking plate 6 is only half of the height of the filter plate 5 .

[0036] Specifically, Figure 2 As shown, a filter screen 7 is disposed inside the storage bucket 303, and the filter screen 7 divides the interior of the storage bucket 303 into two spaces of equal size.

[0037] First, the liquid in the liquid storage tank 201 is extracted and pressurized by the hydraulic pump 202, and then the liquid is pushed into the water outlet pipe 203. At the end of the water outlet pipe 203, the liquid is atomized into fine droplets by the atomizing nozzle 204. These atomized droplets are mixed with air in the air chamber pipe body 1 to form a gas-liquid mixture. Inside the air chamber pipe body 1, the fan 4 runs to generate airflow. This airflow helps the atomized droplets to mix better with the air and push the mixture to flow downward. At the same time, the airflow generated by the fan 4 also helps to blow up the dust or other particles in the air chamber pipe body 1. When these dust or particles are blown up, they will pass through the filter plate 5. The function of the filter plate 5 is to capture and filter out these particles, so that clean air can pass through and the dust is trapped. In order to improve the filtering effect, a baffle plate 6 is also provided on one side of the filter plate 5. The height of the baffle plate 6 is the height of the filter plate 5, which can increase the contact area between the particles and the filter plate 5 and improve the filtering efficiency. As time goes by, a certain amount of dust will accumulate on the filter plate 5. In order to clean the dust, the feed pipe 301 is arranged below the filter plate 5. When it is necessary to clean the dust, the feed pipe 301 is opened. The dust falls into the collection bucket 302 through the feed pipe 301 under the action of gravity. The collection bucket 302 is located below the feed pipe 301 and is used to collect the dust falling from the filter plate 5. Finally, the dust in the collection bucket 302 is collected by a threaded storage barrel 303. A filter screen 7 is arranged inside the storage barrel 303. The filter screen 7 divides the interior of the storage barrel 303 into two spaces of the same size. When dust and water fall into the storage barrel 303, the dust particles will be blocked by the filter screen 7 in the upper layer, and the waste liquid will be deposited in the lower layer. This design is convenient for users to perform solid-liquid separation.

[0038] Specifically, Figure 3 As shown, a reinforcing plate 8 is provided between the air chamber pipe body 1 and the feed pipe 301 , and the reinforcing plate 8 is made of 310 stainless steel.

[0039] Specifically, Figure 3 As shown, gripping handles 9 for disassembling and installing the storage bucket 303 are provided on both sides of the storage bucket 303 .

[0040] The reinforcing plate 8 is arranged between the air chamber pipe body 1 and the feed pipe 301. Its main function is to enhance the stability and durability of the structure. Since the air chamber pipe body 1 and the feed pipe 301 are key components in the system, they need to withstand the vibration and pressure generated by the fan 4, hydraulic pump 202 and other equipment. By using 310 stainless steel as the material of the reinforcing plate 8, it can be ensured that it has high corrosion resistance and high temperature oxidation resistance, so that it can maintain stable performance in various working environments. In addition, the reinforcing plate 8 can also effectively prevent the air chamber pipe body 1 and the feed pipe 301 from vibrating or pressuring. The main function of the holding handle 9 is to facilitate the user to disassemble and install the storage bucket 303. When cleaning or replacing the storage bucket 303, the user can easily lift and put down the storage bucket 303 by holding the handle 9, which reduces the complexity and labor intensity of the operation. In addition, the design of the holding handle 9 can also ensure that the user can stably control the position and direction of the storage bucket 303 during operation to avoid accidental collision or falling. By adding the holding handle 9, the humanized design of the system is improved, making the user's operation more convenient and safe.

[0041] By adopting the above technical solution, the problem that the inner wall of the air chamber pipe in the existing boiler air chamber is cleaned by a hard-bristle brush, but no matter how the dust is cleaned, some dust will still adhere to the corners of the inner wall of the pipe that cannot be cleaned is solved.

[0042] Working principle: When the present application is in use, first, the liquid in the liquid storage tank 201 is extracted and pressurized by the hydraulic pump 202, and then the liquid is pushed into the water outlet pipe 203. At the end of the water outlet pipe 203, the liquid is atomized into fine droplets by the atomizing nozzle 204. These atomized droplets are mixed with air in the air chamber pipe body 1 to form a gas-liquid mixture, and enter the discharge pipe 301 inside the air chamber pipe body 1. The fan 4 generates airflow when it runs. This airflow helps the dust to be blown to the bottom of the atomizer and pushes the mixture to flow downward. At the same time, the airflow generated by the fan 4 also helps to blow up the dust or other particles in the air chamber pipe body 1. When these dust or particles are blown up, they will pass through the filter plate 5. The function of the filter plate 5 is to capture and filter out these particles, so that clean air can pass through and the dust is trapped. In order to improve the filtering effect, a blocking plate 6 is also provided on one side of the filter plate 5. The blocking plate 6 is half the height of the filter plate 5, so that the contact area between the particles and the filter plate 5 can be increased, and the filtering efficiency can be improved. As time goes by, a certain amount of dust will accumulate on the filter plate 5. In order to clean the dust, the feed pipe 301 is arranged below the filter plate 5. When the dust needs to be cleaned, the feed pipe 301 is opened, and the dust and waste liquid fall into the collection bucket 302 through the feed pipe 301 under the action of gravity. The collection bucket 302 is located below the feed pipe 301 and is used to collect the dust falling from the filter plate 5. Finally, the dust in the collection bucket 302 is collected by a threaded storage barrel 303. A filter screen 7 is arranged inside the storage barrel 303. The filter screen 7 divides the interior of the storage barrel 303 into two spaces of the same size. When dust and water fall into the storage barrel 303, the dust particles will be blocked by the filter screen 7 in the upper layer, and the waste liquid will be deposited in the lower layer. This design facilitates users to perform solid-liquid separation.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
