Description

Technical Field

[0001] The utility model relates to the technical field of ash conveying, in particular to an automatic pneumatic ash conveying system. Background Art

[0002] Thermal power generation, or thermal power, refers to a method of generating electricity by converting the heat energy generated by the combustion of combustibles (mainly coal, but also other combustibles such as natural gas, fuel oil, etc.) into electrical energy through a power generation device. The fly ash generated by coal combustion in a thermal power plant is collected in the dust collector hopper, then falls into the ash silo pump, and is transported to the ash storage by compressed air. Pneumatic ash conveying systems have been widely used in thermal power plants. However, the traditional pneumatic ash conveying system has a low degree of automation, including blockage removal and adjustment of ash conveying intervals, which requires manual operation by operators, resulting in a large workload. Utility Model Content

[0003] The utility model provides an automatic pneumatic ash conveying system, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] An automatic pneumatic ash conveying system comprises an outer sleeve, a feed pipe, a purge pipe and a cavity, wherein the outer sleeve is provided with a cavity, the inner side of the outer sleeve is provided with a feed pipe, the top end of the feed pipe is a feed inlet, the cavity is connected with the feed pipe through a purge pipe, both ends of the feed pipe are provided with flanges, a plurality of feed pipes are connected and fixed by flanges and bolts, an air pressure sensor is installed at the feed end of the feed pipe, and the air pressure sensor is electrically connected to a controller.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, an air inlet pipe is provided on the outer sleeve, and the air inlet pipe is communicated with the cavity.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] The air inlet pipe is directly connected to the cavity inside the outer sleeve, ensuring that the compressed air can enter the cavity quickly and efficiently. This design reduces the loss of energy during the transmission process and improves the overall efficiency of the system.

[0010] Furthermore, a purge port is provided through the feed pipe, and the interior of the feed pipe is connected to the purge pipe through the purge port.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The design of the purge port allows the compressed air in the purge pipe to directly enter the discharge pipe to directly purge and disturb the ash. This design helps prevent the ash from agglomerating or clogging in the discharge pipe during transportation, ensuring smooth and continuous transportation.

[0013] Furthermore, the air inlet pipe is connected to an air pump.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] As the power source of the system, the air pump can continuously and stably provide compressed air to the air inlet pipe. This stable air source is the basis for the normal operation of the pneumatic ash conveying system, ensuring the smooth transportation of ash in the pipeline. The compressed air provided by the air pump forms a high-speed airflow in the air inlet pipe, which has a strong blowing and pushing effect on the ash. This strong blowing and pushing effect helps to reduce the friction resistance and adhesion of the ash in the pipeline, thereby improving the transportation efficiency.

[0016] Furthermore, a solenoid valve is installed between the air pump and the air intake pipe, and the solenoid valve is electrically connected to the controller.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] Through the electrical connection between the solenoid valve and the controller, the system can realize automatic air source control. The controller can automatically open or close the solenoid valve according to the preset program or real-time working condition data, thereby controlling the start and stop of the air pump and the delivery of compressed air. This kind of automatic control greatly reduces the need for manual operation and improves the automation level and production efficiency of the system.

[0019] Furthermore, the angle between the purge pipe and the feed pipe is fifteen degrees.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The 15-degree angle design ensures that the compressed air ejected from the purge pipe impacts the ash in the discharge pipe at a suitable angle. This angle design will not cause the airflow to directly hit the pipe wall, resulting in energy loss, but can also effectively purge and disturb the ash, preventing the ash from agglomerating or clogging in the discharge pipe.

[0022] Furthermore, the purge pipes are distributed in a circular array along the tangent line of the feed pipe on the outside of the feed pipe.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The purge pipes arranged in an annular array can ensure that the outer side of the feed pipe is evenly purged. This design allows compressed air to be sprayed along the tangent direction of the feed pipe to form a continuous, surrounding purge airflow, thereby effectively preventing the ash from accumulating or agglomerating near the outer wall of the feed pipe.

[0025] Furthermore, a plurality of purge pipes are provided between the outer sleeve and the feed pipe.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] Multiple groups of purge pipes can purge the ash in the discharge pipe from different angles and positions, forming a more comprehensive and uniform purge effect. This design helps to completely remove the lumps and accumulations in the ash, ensuring the smooth transportation of the ash. By enhancing the purge effect, multiple groups of purge pipes can significantly improve the fluidity of the ash and reduce the resistance and energy consumption of the ash during transportation. This helps to improve the overall transportation efficiency of the system and reduce operating costs.

[0028] The beneficial effects of the utility model are:

[0029] Powered by an air pump and combined with the design of the air inlet pipe and cavity, the system can efficiently deliver compressed air to the outer sleeve, and use the kinetic energy and pressure energy of the air to transport the ash. This pneumatic conveying method has the characteristics of low flow rate, low resistance, and high efficiency, which can significantly improve the ash conveying efficiency. There are multiple groups of purge pipes between the outer sleeve and the discharge pipe, and the angle between the purge pipe and the discharge pipe is fifteen degrees, and they are distributed in a circular array along the tangent of the discharge pipe. This design can ensure that the ash is fully purged and disturbed during the transportation process, prevent the ash from agglomerating or clogging in the pipeline, and ensure smooth transportation.

[0030] The system controls the solenoid valve through the controller to start and stop the air pump and control the delivery of compressed air. At the same time, the air pressure sensor installed in the feeding pipe can monitor the air pressure in the pipeline in real time and feed the data back to the controller. This intelligent control and automation design enables the system to automatically adjust the working state according to the actual situation in the pipeline, improving the stability and reliability of the system.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0042] See also Figures 1 to 4 As shown, the embodiments provided by the utility model:

[0043] Embodiment 1: An automatic pneumatic ash conveying system includes an outer sleeve 8, a feed pipe 9, a purge pipe 10 and a cavity 11. The outer sleeve 8 is provided with a cavity 11. The outer sleeve 8 is provided with an air inlet pipe 5, and the air inlet pipe 5 is connected to the cavity 11. The air inlet pipe 5 is directly connected to the cavity 11 in the outer sleeve 8, ensuring that compressed air can enter the cavity 11 quickly and efficiently. This design reduces the loss of energy during the transmission process and improves the overall efficiency of the system. The air inlet pipe 5 is connected to an air pump 1. As the power source of the system, the air pump 1 can continuously and stably provide compressed air to the air inlet pipe 5. This stable air source is the basis for the normal operation of the pneumatic ash conveying system and ensures the smooth transportation of ash in the pipeline. The compressed air provided by the air pump 1 forms a high-speed airflow in the air inlet pipe 5, which has a strong purge and push effect on the ash. This strong purging and pushing action helps to reduce the friction resistance and adhesion of the ash in the pipeline, thereby improving the transportation efficiency. A solenoid valve 3 is installed between the air pump 1 and the air inlet pipe 5, and the solenoid valve 3 is electrically connected to the controller 2. The solenoid valve 3 is controlled by the controller 2. Through the electrical connection between the solenoid valve 3 and the controller 2, the system can realize automatic air source control. The controller 2 can automatically open or close the solenoid valve 3 according to the preset program or real-time working condition data, thereby controlling the start and stop of the air pump 1 and the delivery of compressed air. This automatic control greatly reduces the need for manual operation and improves the automation and production efficiency of the system. A feed pipe 9 is provided on the inner side of the outer sleeve 8, and the top of the feed pipe 9 is a feed port 7. The cavity 11 is connected to the feed pipe 9 through a purge pipe 10. Multiple groups of purge pipes 10 are provided between the outer sleeve 8 and the feed pipe 9. Multiple groups of purge pipes 10 can purge the ash in the feed pipe 9 from different angles and positions, forming a more comprehensive and uniform purge effect. This design helps to completely remove the lumps and accumulations in the ash and ensure the smooth transportation of the ash. By enhancing the purging effect, multiple groups of purging pipes 10 can significantly improve the fluidity of the ash and reduce the resistance and energy consumption of the ash during transportation. This helps to improve the overall transportation efficiency of the system and reduce operating costs. The angle between the purging pipe 10 and the discharge pipe 9 is fifteen degrees. The fifteen-degree angle design can ensure that the compressed air ejected from the purging pipe 10 impacts the ash in the discharge pipe 9 at a suitable angle. This angle design will not cause the airflow to directly rush to the pipe wall to cause energy loss, but can effectively purge and disturb the ash to prevent the ash from caking or clogging in the discharge pipe 9. The purging pipes 10 are distributed in a circular array along the tangent of the discharge pipe 9 on the outside of the discharge pipe 9. The purging pipes 10 distributed in a circular array can ensure that the outside of the discharge pipe 9 is evenly purged.This design enables compressed air to be ejected along the tangential direction of the feed pipe 9, forming a continuous, surrounding purge airflow, thereby effectively preventing the ash from accumulating or agglomerating near the outer wall of the feed pipe 9. A purge port 12 is provided through the feed pipe 9, and the interior of the feed pipe 9 is connected to the purge pipe 10 through the purge port 12. The design of the purge port 12 allows the compressed air in the purge pipe 10 to directly enter the interior of the feed pipe 9, and directly purge and disturb the ash. This design helps to prevent the ash from agglomerating or clogging in the feed pipe 9 during transportation, ensuring the smoothness and continuity of transportation. Flanges 6 are provided at both ends of the feed pipe 9, and multiple feed pipes 9 are connected and fixed by flanges 6 and bolts. An air pressure sensor 4 is installed at the feed end of the feed pipe 9, and the air pressure sensor 4 is electrically connected to the controller 2. The data in the feed pipe 9 is fed back to the controller 2 through the air pressure sensor 4, so that the controller 2 can interlock the solenoid valve 3.

[0044] When an automatic pneumatic ash conveying system based on Example 1 is used: the air pump 1 provides power, and combined with the design of the air inlet pipe 5 and the cavity 11, the system can efficiently convey compressed air into the outer sleeve 8, and use the kinetic energy and pressure energy of the air to achieve the conveying of ash. This pneumatic conveying method has the characteristics of low flow rate, small resistance, and high efficiency, which can significantly improve the ash conveying efficiency, and multiple groups of purge pipes 10 are provided between the outer sleeve 8 and the discharge pipe 9, and the angle between the purge pipe 10 and the discharge pipe 9 is fifteen degrees, and they are distributed in a circular array along the tangent of the discharge pipe 9. This design can ensure that the ash is fully purged and disturbed during the conveying process, prevent the ash from agglomerating or clogging in the pipeline, and ensure the smoothness of the conveying.

[0045] The system controls the solenoid valve 3 through the controller 2 to realize the start and stop of the air pump 1 and the delivery control of compressed air. At the same time, the air pressure sensor 4 installed in the feeding pipe 9 can monitor the air pressure in the pipeline in real time and feed the data back to the controller 2. This intelligent control and automation design enables the system to automatically adjust the working state according to the actual situation in the pipeline, improving the stability and reliability of the system.
