Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline for a dust collecting system, in particular to a dust collecting pipeline with a long pipeline and a large amount of dust. Background Art
[0002] Existing compound fertilizer plants generally adopt a closed dust collection process in granulation, drying, screening, and material conveying equipment. Dust from each equipment is often sucked through pipes to a centralized dust removal equipment system (cyclone dust collection, bag dust collection + washing and recovery and other tail gas systems) to meet environmental protection requirements. In general, the same dust collection equipment (system) needs to collect dust from multiple dust release sources. The dust collection pipe is long, has many bends, and has uneven power, which leads to frequent blockages in the dust collection pipe. The plant needs to be stopped regularly to clean the dust accumulated in the pipe in order to produce normally, which seriously affects the production capacity and operation efficiency of the plant. Summary of the invention
[0003] In order to overcome the problem that the existing dust collecting pipeline is often blocked and the pipeline needs to be stopped regularly to clean the dust accumulated in the pipeline for normal production, and to ensure the continuous, stable and long-term operation of the device, the utility model provides a dust collecting pipeline device for a dust collecting system, the dust collecting pipeline is provided with an air cannon, and a sedimentation chute is provided in a long-distance horizontal section. The air cannon is installed on the dust collecting pipeline in sequence in a multi-point manner. The air cannon adopts an automatic control program to automatically start and stop according to needs to break the arch and disturb the dust accumulated in the dust collecting pipeline, so as to prevent dust from gathering and clogging in the dust collecting pipeline. The dust after the arch breaking and disturbance still relies on the existing dust collecting power (exhaust fan) to extract and dispose of the dust, so as to ensure the long-term operation of the dust collecting system.
[0004] The technical solution of the utility model is: a dust collecting pipeline for a compound fertilizer device that does not require cleaning, comprising a dust collecting pipeline, an air cannon tube, a sedimentation chute, and a dust collecting branch pipe is arranged on the dust collecting pipeline;
[0005] Multiple air cannon tubes are provided on the dust collection pipe and the dust collection branch pipe;
[0006] A sedimentation chute is provided in the long horizontal section of the dust collection pipeline.
[0007] The air cannon tubes are installed on the dust collecting pipe and the dust collecting branch pipe in a multi-point manner at a certain interval. The air cannon tubes in the horizontal section of the dust collecting pipe are installed at the bottom of the pipe.
[0008] The distance between air cannon tubes is 1m-2m.
[0009] The air cannon tube is installed on the pipeline in a horizontal or inclined manner according to the material conveying direction. When it is installed in an inclined manner, the inclination angle is 20-50°.
[0010] A gravity flap valve is provided at the bottom of the sedimentation chute to discharge the settled dust to the dust collection belt.
[0011] A pipe clamp valve is provided on the dust collecting branch pipe to adjust the opening of each branch pipe.
[0012] Air cannon tubes are installed on the dust collecting pipe in sequence at a certain interval. The air cannon tubes use an automatic control program to automatically start and stop according to needs to break the arch and disturb the dust accumulated in the dust collecting pipe. The dust after the arch breaking and disturbance still relies on the existing dust collecting power (exhaust fan) to extract the dust and enter the subsequent dust collecting device for disposal. A sedimentation chute is set up in the long horizontal section. The settled dust enters the dust collection belt and returns to the production system for recycling. The dust collecting branch pipe is provided with a pipe clamp valve with the same diameter as the branch pipe. The pipe clamp valve is used to adjust the opening of each branch pipe to ensure the negative pressure balance of the entire dust collecting system pipeline. At the same time, the pipe clamp valve is set to automatically switch on and off regularly to ensure that the pipe clamp valve position is not blocked by dust accumulation. After the application of this utility model, it is only necessary to set the frequency of air cannon action in the air cannon tube according to needs to ensure that the dust collecting pipe is not blocked by dust accumulation, and to ensure the long-term continuous and stable operation of the device.

[0014] In the figure: dust collecting pipe 1, air cannon tube 2, pipe clamp valve 3, sedimentation chute 4, gravity flap valve 5, dust collecting belt 6, dust collecting branch pipe 7. DETAILED DESCRIPTION
[0015] As attached Figure 1 As shown:
[0016] A dust collecting pipeline for a compound fertilizer device that does not require cleaning comprises a dust collecting pipeline 1, an air cannon tube 2, and a sedimentation chute 4. The dust collecting pipeline 1 is provided with a dust collecting branch pipe 7; the dust collecting pipeline 1 and the dust collecting branch pipe 7 are both provided with a plurality of air cannon tubes 2; and the long horizontal section of the dust collecting pipeline 1 is provided with a sedimentation chute 4.
[0017] The air cannon tubes 2 are installed on the dust collecting pipe 1 and the dust collecting branch pipe 7 in sequence at intervals of 1.5 m in a multi-point manner. The air cannon tubes 2 of the horizontal section of the dust collecting pipe are installed at the bottom of the pipe.
[0018] The air cannon tube 2 is installed on the pipeline at an angle of 30° according to the material conveying direction.
[0019] A gravity flap valve 5 is provided at the lower part of the sedimentation chute 4 for discharging the settled dust to the dust collection belt 6 .
[0020] A pipe clamp valve 3 is provided on the dust collecting branch pipe 7 to adjust the opening of each branch pipe.
[0021] The air source of air cannon 2 adopts factory compressed air with a pressure of 0.5Mpa--0.8Mpa.
[0022] The sedimentation chute 4 adopts a chute structure that is wide at the top and narrow at the bottom.
[0023] Air cannon 2 uses an automatic control program to automatically start and stop as needed to break and disturb the dust accumulated in the dust collection duct. The dust after breaking and disturbance still relies on the existing dust collection power (exhaust fan) to draw the dust into the subsequent dust collection device for disposal.
[0024] In order to ensure that the pressure of the dust collection system fluctuates within a controllable range, the air cannon tube 2 is not set to operate simultaneously in large quantities. In actual operation, the installation points of each air cannon tube 2 start and stop in sequence (the start and stop interval of each air cannon is controlled within 10-15 minutes), and the dust collection pipeline can still be guaranteed not to be blocked by material accumulation.
[0025] A pipe clamp valve 3 is provided on the dust collecting branch pipe 7 to adjust the opening of each branch pipe to ensure the negative pressure balance of the entire dust collecting system pipeline;
[0026] The pipe clamp valve 3 arranged on the dust collecting branch pipe 7 has the same diameter as the branch pipe, and the pipe clamp valve 3 is arranged to have a regular switching action to ensure that the position of the pipe clamp valve 3 is not blocked by dust accumulation.
[0027] By adopting the above structure, it is only necessary to set the air cannon action frequency according to the needs to ensure that the dust collection pipeline is not blocked by dust accumulation, thereby ensuring the long-term continuous and stable operation of the device.
