Description

Technical Field

[0001] The utility model belongs to the technical field of energy-enhancing blowing devices for conveying pipelines, in particular to an energy-enhancing blowing device for pneumatic conveying pipelines of powder products. Background Art

[0002] When dense phase transportation is carried out in long-distance conveying pipelines, high-pressure and low-gas-speed transportation is usually used to transport materials. Under normal circumstances, the materials will accumulate at the bottom of the pipeline. Compressed air enters the long-distance conveying pipeline and flows over the surface of the conveyed materials at a certain speed. The fast-flowing compressed air passes through the surface of the materials, and the materials are driven to circulate forward in piles, thereby forming sections of plunger-shaped sand dunes in the conveying pipe. Therefore, it takes time to introduce compressed gas into the long-distance conveying pipeline to push the materials forward, and the power source of the material movement mainly comes from the high and low pressure difference formed by the compressed air entering the pipeline;

[0003] However, in the existing dense phase conveying, because the long-distance conveying pipeline spans multiple workshops, although the compressed gas is injected in sections, the gas pressure becomes low due to the material pushing consumption over a certain distance, and the gas blowing effect of the material in the tail section is not good. Therefore, it is urgently necessary to design an energy-enhancing blowing device for pneumatic conveying pipelines of powder products to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an energy-boosting blowing device for a pneumatic conveying pipeline of powder products, which solves the problem that the material cannot be blown due to insufficient power source for material movement in a long-distance conveying pipeline.

[0005] In order to solve the above technical problems, the utility model provides an energy-boosting blowing device for a pneumatic conveying pipeline of powder products. The conveying pipeline is composed of several sections of pipelines. The energy-boosting blowing devices are divided into several groups, and each group of the energy-boosting blowing devices includes a first gas pipeline, a second gas pipeline, an anti-backflow component and several nozzle assemblies, and a short-section pipeline installed between two adjacent sections of the conveying pipeline. The first gas pipeline is connected to a gas storage system, the anti-backflow component is arranged at the end of the short-section pipeline, the air inlet end of the second gas pipeline is connected to the first gas pipeline, and the air outlet end is connected to the short-section pipeline through several nozzle assemblies, and the injection end of each nozzle assembly penetrates into the short-section pipeline of the corresponding section.

[0006] Furthermore, the second gas pipeline spiral disk is arranged on the short section pipeline.

[0007] Furthermore, the second gas pipeline is provided with a solenoid valve, and the solenoid valve is connected to a one-way valve.

[0008] Furthermore, the anti-backflow assembly includes a fixed seat, a rotating shaft and a baffle plate. The fixed seat is connected to the end of the short section of the pipe through a flange. A limiting step is provided in the fixed seat. The baffle plate is arranged in the fixed seat through the rotating shaft. The baffle plate contacts the limiting step to block a certain amount of gas from flowing back into the previous section of the delivery pipeline.

[0009] Furthermore, several of the nozzle assemblies include injection pipes and nozzles, the injection pipes are obliquely arranged at intervals on the spirally arranged second gas pipe, and their injection ends pass through the side walls of the short section pipe and extend into the short section pipe and are connected to the nozzles, and the injection end of each nozzle is arranged toward the next section of the conveying pipe.

[0010] Furthermore, the inclination angle between each of the injection pipes and the corresponding section of the short pipe section is 15-30 degrees.

[0011] Beneficial effects of the utility model: the design of the energy-boosting blowing device between the two sections of the conveying pipeline in the utility model can effectively add gas into the corresponding short-section pipeline in sections, and at the same time, the plurality of nozzle assemblies arranged in a spiral can be selected to intermittently or continuously supply air to the short-section pipeline according to needs. The intermittent air supply method can effectively save the amount of compressed air. Intermittently or continuously supplying air to the short-section pipeline can improve the conveying effect of powder products, and at the same time, it can also prevent the pressure of the compressed gas from being released to low pressure in a short time, so as to solve the problem that the pressure is reduced when the airflow flows in the long-stroke pipeline and cannot play the role of conveying or blowing away powder products;

[0012] The design of the anti-backflow component can effectively reduce the problem of ineffective gas loss in the short section of the pipeline caused by the gas in the conveying pipeline flowing back to the previous section of the conveying pipeline during material transportation;

[0013] The one-way valve on the second gas pipeline is designed to prevent the material from flowing back into the second gas pipeline when the powder in the conveying pipeline is blown, thereby preventing the first gas pipeline from being blocked.

[0014] The design of the nozzle assembly being arranged in the spirally arranged second gas pipeline can form a spiral airflow by using the nozzles tilted at multiple angles. The spiral airflow blows the powder in the corresponding short section of the pipeline to improve the conveying efficiency of the conveying pipeline.

[0015] The design of the solenoid valve and the one-way valve on the second gas pipeline can effectively prevent powder from entering the second gas pipeline by double interception. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings of the utility model specification to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0024] In a specific embodiment of the present invention, Figure 1-Figure 5As shown, a power-enhancing blowing device for a pneumatic conveying pipeline of powder products is specifically disclosed. The conveying pipeline is composed of a plurality of pipeline sections, and the power-enhancing blowing device 2 is a plurality of groups, and each group of the power-enhancing blowing device 2 includes a first gas pipeline 21, a second gas pipeline 22, an anti-backflow component 23 and a plurality of nozzle components 24, and a short pipe section 1 installed between two adjacent conveying pipeline sections. The design of the power-enhancing blowing device 2 between the two conveying pipeline sections can effectively add gas into the corresponding short pipe section 1 in sections, and at the same time, the plurality of nozzle components 24 arranged in a spiral can be selected to intermittently or continuously supply air to the short pipe section 1 as needed. The intermittent air supply method can effectively save the amount of compressed air. The intermittent or continuous air supply to the short pipe section 1 can improve the conveying effect of the powder product, and at the same time, it can also prevent the pressure of the compressed gas from being leaked to a low pressure in a very short time, so as to solve the problem that the pressure is reduced when the airflow flows in a long-stroke pipeline and cannot play the role of conveying or blowing away the powder product.

[0025] The first gas pipeline 21 is connected to a gas storage system, the anti-backflow component 23 is arranged at the end of the short-section pipeline 1, the air inlet end of the second gas pipeline 22 is connected to the first gas pipeline 21, and the air outlet end is connected to the short-section pipeline 1 through a plurality of nozzle assemblies 24, and the injection end of each nozzle assembly 24 penetrates into the short-section pipeline 1 of the corresponding section.

[0026] The spiral disk of the second gas pipeline 22 is arranged on the short section pipeline 1. The second gas pipeline 22 is a spiral pipeline. The second gas pipeline 22 is provided with a solenoid valve 3, and the solenoid valve 3 is connected to a one-way valve 4.

[0027] The backflow prevention component 23 includes a fixed seat 231, a rotating shaft 232 and a blocking plate 233. The fixed seat 231 is connected to the end of the short-section pipeline 1 through a flange. A limiting step 2311 is provided in the fixed seat 231. The blocking plate 233 is arranged in the fixed seat 231 through the rotating shaft 232. The blocking plate 233 contacts the limiting step 2311 to block a certain amount of gas from flowing back into the upper section of the conveying pipeline. The design of the backflow prevention component 23 can effectively reduce the problem of ineffective loss of gas in the short-section pipeline 1 caused by the gas in the short-section pipeline 1 flowing back into the upper section of the conveying pipeline during material transportation.

[0028] The design of the baffle plate 233, the rotating shaft 232 and the limiting step 2311 can effectively prevent the gas from flowing back from the short section of the pipe 1 to the previous short section of the pipe 1, and the baffle plate 233 is not designed with a limiting structure on the end face close to the next short section of the pipe 1, so that the gas or medium can open it under pressure to transport the material to the next process or outlet, that is, the powder can be blown away and the powder can be transported at the same time, thereby improving the transportation efficiency of the powder.

[0029] Several nozzle assemblies 24 include injection pipes 241 and nozzles 242. The injection pipes 241 are obliquely arranged at intervals on the spirally arranged second gas pipeline 22, and their injection ends pass through the side wall of the short-section pipeline 1 and extend into the short-section pipeline 1, and are connected to the nozzles 242. The injection end of each nozzle 242 is arranged toward the next section of the conveying pipeline. The inclination angle between each injection pipe 241 and the corresponding section of the short-section pipeline 1 is 15-30 degrees, and the preferred inclination angle is 20 degrees. The design of the above-mentioned nozzle assembly 24 arranged in the spirally arranged second gas pipeline 22 can utilize the multi-angle inclined nozzles 242 to form a spiral airflow, and the spiral airflow blows the powder in the corresponding section of the short-section pipeline 1 to improve the conveying efficiency of the conveying pipeline.

[0030] The workflow of this utility model:

[0031] When it is necessary to intake air into the powder in the intermittently arranged conveying pipelines or the continuously arranged conveying pipelines, the control unit controls the one-way valve 4 on the second gas pipeline 22 on the short-section pipeline 1 on the side of the conveying pipeline to be air-intake to open, that is, the solenoid valve 3 is opened at the same time, and the gas storage system transports the compressed air from the first gas pipeline 21 to the second gas pipeline 22, and the second gas pipeline 22 spirally transports the compressed gas to each nozzle assembly 24, and sprays the compressed air into the short-section pipeline 1 through the nozzle 242 in a spiral manner to transport the powder. The gas pressure opens the baffle 233 of the anti-backflow assembly 23 of the next short-section pipeline 1, and the powder enters the next section. In the conveying pipeline, when more gas is needed, continuous air intake can be selected, and the baffle 233 of the anti-backflow component 23 between the next section of the conveying pipeline and the short section of the pipeline 1 can be opened to enter the next section of the conveying pipeline, and finally output from the outlet of the long-distance conveying pipeline; when less gas is needed, intermittent air intake can be selected, and the conveyed gas passes through the next section of the conveying pipeline and the short section of the pipeline 1 in turn and enters the next section of the conveying pipeline, and the first gas pipeline 21 takes air into the short section of the pipeline 1 on one side of the next section of the conveying pipeline, and finally outputs from the outlet of the long-distance conveying pipeline, so as to achieve the effect of continuous material power source, and at the same time, it can save the amount of compressed air, thereby improving the material conveying effect.

[0032] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
