Description

Technical Field

[0001] The invention relates to the technical field of dust removal, in particular to a powder sprayer for conveying powder for pre-treating air entering a filter cartridge of dust removal equipment. Background Art

[0002] At present, domestic industrial dust removal equipment is unable to completely remove oily, sticky flue gas, flue gas mixed with sparks, water-containing, and high-dust air before entering the dust collector, which will inevitably cause the dust removal filter material to be frequently blocked and unable to work normally after being stuck, resulting in increased frequency of filter material replacement, maintenance, and operating costs, and increased uncertainty in equipment downtime. Especially in the working environment of underground pipelines, when the water and dust content are high and the oil content at the construction site is high, effective treatment before air filtration is an important guarantee to ensure a clean environment and good health, and is also a necessary means to extend the service life of the filter paper and reduce safety accidents.

[0003] The prior art proposes a technical improvement structure of adding a powder sprayer before air filtration. The patent with publication number CN103961953A and titled "A special dust collector for sticky dust and dust removal method" provides a special dust collector for sticky dust, including a vertical dust collector, wherein a mixing cylinder is provided below the filter cartridge of the vertical dust collector, the lower end of the mixing cylinder is located on the cylinder, the upper end of the mixing cylinder is sealed relative to the upper end of the filter cartridge, a feeding nozzle is provided at the lower part of the mixing cylinder, the feeding nozzle is connected to a pneumatic conveyor through a feeding pipe, and the pneumatic conveyor is located at the suction In the conveying pipe of the dust hood, when the dust collector sucks the sticky dust, the negative pressure airflow generated by the centrifugal fan absorbs the sticky dust through the dust hood. At the same time, the pneumatic conveyor located in the conveying pipe of the dust hood generates a siphon when the negative pressure airflow passes through, sucking the anti-sticking powder (such as talcum powder) in the mixing barrel into the pneumatic conveyor through the conveying pipe and mixing it with the sticky dust passing through the pneumatic conveyor. Then, it enters the filter cartridge, and after being filtered by the filter cartridge, it falls into the mixing barrel and is mixed with the sticky dust passing through the pneumatic conveyor. Then, it enters the filter cartridge. This device mixes the anti-sticking powder into the dust in the dust hood to reduce the viscosity of the dust. However, in engineering practice, due to the friction and electrostatic effect between the powder particles, problems such as wall adhesion, arching and bridging, and rat holes are prone to occur, resulting in the powder being unable to be uniform under the action of the negative pressure airflow, and the weight cannot be controlled, which will directly affect the effect of the pre-treatment of the filtered air.

[0052] In addition, the specific implementation methods of some control systems of the powder forming device, as well as the structures, principles or other structural shapes that achieve equivalent functions by generating signals from sensors and then converting them into manipulation and visual scenes, should be easy for technical personnel in this field to conceive, so they will not be described in detail here.

[0053] In addition, it also includes cables and other auxiliary equipment, such as control switches, etc. This should be easy to conceive for those skilled in the art, so it will not be described in detail here.

[0054] The powder forming device provided in the above embodiments of the present application has at least the following characteristics:

[0055] In the powder forming device provided in the embodiment of the present application, the silo is fixed in the air with the first mounting bracket and the body part, which improves the monitoring accuracy of the powder quality inside the storage barrel and improves the detection sensitivity; the third mounting bracket and the second mounting bracket are arranged on the side of the silo, and the through hole opened in the second mounting bracket is arranged on the same axis as the through hole opened in the third mounting bracket, which is convenient for the assembly and maintenance of the transmission part; by connecting the powder conveying pipe with the silo and cleverly arranging the rotary shaft at the connection between the powder conveying pipe and the silo, the powder is transferred from the silo to the powder spraying pipe under the action of the spiral blade, thereby realizing timing and Quantitative and continuous powder output; the powder conveying pipe and the silo are arranged in parallel and spaced apart, so that the powder can be measured during the circuitous transportation of the pipeline, making the structure of the whole set of powder sprayer relatively compact and with high space utilization; the weighing sensor arranged on the storage barrel can grasp the residual powder in the storage barrel in real time, and can send out an alarm or shutdown signal when the threshold is reached, thereby ensuring the safety and reliability of the whole purification system; the sensor and the sensor bracket can be matched with each other to monitor the transmission part in real time, and then the operating status of the powder sprayer can be judged, which improves the efficiency of powder spraying. The automation and intelligence of the powder maker; the stirring rollers arranged at intervals along the axial direction of the stirring shaft can fully stir the powder inside the working part; the crossbeam arranged at the end of the stirring roller away from the stirring shaft improves the stirring efficiency, especially for the powder on the inner wall of the working part, reduces the aggregation of the powder on the inner wall, thereby avoiding many disadvantages caused by the powder sticking to the wall; through the connection between the reducer and the rotary shaft drive, through the transmission mechanism arranged on the rotary shaft and the stirring mechanism, and respectively connected to the rotary shaft and the stirring mechanism, a transmission linkage is formed, which can be conveniently driven by the reducer. The driving rotary shaft and the stirring mechanism rotate at the same time, thereby realizing the stirring of the powder in the cavity inside the working part, and driving the powder entering the conveying part from the working part at the same time; by controlling the speed of the reducer, the powder entering the conveying part from the working part can be accurately controlled, and the timed, quantitative and continuous powder output can be realized. It is not affected by the friction between the powder particles, electrostatic effects and other factors that cause wall sticking, arching and bridging, rat holes and other problems. It can effectively solve the problems of uneven discharge and uncontrollable dosage caused by the characteristics of the powder. It has a simple structure, convenient operation, strong practicality, and is easy to promote and use.
