Abstract
The utility model discloses an air supplementation device of a pneumatic conveying pipeline, and belongs to the technical field of pneumatic conveying pipeline structures. The air supplementation device aims at overcoming the defect that blocking easily occurs on bends, other components and long horizontal pipe sections of a pneumatic conveying pipeline at present on the premise that energy is relatively saved. The air supplementation device comprises a conveying pipe, wherein air distribution pipes are arranged on the external of the conveying pipe in a surrounding mode, a plurality of jet heads are installed on the air distribution pipes, outer walls of the jet heads are connected with the wall of the conveying pipe in a sealed mode, ports of the jet heads are formed in the conveying pipe, the air discharging current directions of the ports of the jet heads deflect to the conveying air current direction in the conveying pipe, and included angles between the air discharging current directions of the ports of the jet heads and the center line of the conveying pipe are smaller than 90 degrees. The air distribution pipes are communicated with an air supplying pipe. The air supplementation device is suitable for the pneumatic conveying system for solid bulk cargoes.
Description
Technical field
The utility model relates to a kind of Pneumatic conveying pipeline structure technology, particularly relates to a kind of air compensation device of Pneumatic conveying pipeline.
Background technology
Pneumatic Conveying Technology, is to rely on air to form and have the air-flow of certain speed in airtight pipeline, thereby makes material under the effect of air-flow, is suspended in pipeline and by air-flow, drives the technology that is transported to another place simultaneously.Due to pneumatic conveying method, to have delivery system airtight, loss of material is seldom higher with transport efficiency, simultaneously, equipment needed thereby is simple, convenient operation and management, easily realize the Transport Machinery of loose unpacked material, automation, serialization, improved labor condition, the advantages such as shipping and delivery cost have been reduced, therefore, in every profession and trade, for the occasion that will carry out granule Bulk material, adopted widely, especially in food-processing industry, with Pneumatic conveyer, carry as rice, wheat, barley, melon is dry, beans, the materials such as corn more can receive other carrying method cannot than like good result.According to hydromechanical principle, local resistance when air-flow flowing in pipeline will be subject to along journey friction force with by parts such as elbow, reducing pipeline section, threeways; Sometimes, also there will be pipeline in the phenomenon of joint gas leakage; Everything all can cause the loss of pressure of air-flow, be embodied on Pneumatic conveying pipeline, just be easy at the parts such as elbow of pipeline and on long horizontal pipeline section, the material of carrying is because the deficiency of kinetic energy settles down, and causes the obstruction of pipeline and whole delivery system is stopped work.For this reason, there is in order to prevent pipeline the phenomenon of stopping up in people, and the flow of the delivery air of having to increase significantly, makes the speed of air-flow too high; But it is very uneconomic doing like this, had both made consumption of power increase and also can aggravate the wearing and tearing of pipeline and tube fitting and cause the noise of working space to exceed standard.
Summary of the invention
The purpose of this utility model is to provide a kind of air compensation device of Pneumatic conveying pipeline, overcomes current strength and carry the deficiency that is prone to obstruction on the parts such as elbow of pipeline and long horizontal pipeline section under the prerequisite of relative energy-saving.
The utility model is achieved by following technical proposals.
The utility model comprises conveying pipeline, outer surrounding at described conveying pipeline is provided with gas distribution pipe, a plurality of jet thrusts are housed on described gas distribution pipe, the outer wall of described jet thrust and the tube wall of described conveying pipeline is tightly connected, its air nozzle is placed in described conveying pipeline, the air flow line of giving vent to anger of described jet thrust is partial to conveying air flow line in described conveying pipeline and is less than 90 ° with the angle of the line of centers of described conveying pipeline; Described gas distribution pipe is communicated with air supply pipe.The design of the technical program, is to manage on the pipeline of air-transport system, and some resistances partial points large, that obstruction easily occurs is carried out tonifying Qi supercharging.Although, these also want consumption of power for tonifying Qi supercharging with gas, but because these tolerance are carried separately with pipeline, can appropriate design flow and pressure head, therefore, in course of conveying, fluidised form is better, and strengthens, allows air-flow move and make comparisons under the fluidised form worsening the airflow pressure on Pneumatic conveying pipeline once, economical, can allow whole air-transport system generally consumption of power significantly reduce.The quantity of described jet thrust, should decide according to the size of Pneumatic conveying pipeline; The air flow line of giving vent to anger of described jet thrust should approach the flow direction of conveying air-flow as much as possible, that is to say, the angle of the line of centers of give vent to anger air flow line and the described conveying pipeline of described jet thrust is the smaller the better, can reduce like this tonifying Qi air-flow the Radial Perturbation of conveying air-flow is caused to loss of pressure.The air-flow of all described jet thrusts is all provided by gas distribution pipe by described air supply pipe, and the source of the gas of described air supply pipe can share a source of the gas with conveying pipeline, also can arrange separately.
In the utility model, the air-flow phase mutual interference spraying for fear of the described jet thrust of relative direction, simultaneously, the axial distance in Ye Keshi conveying pipeline road bureau portion's tonifying Qi district extends, and described gas distribution pipe is that along the conveying direction of described conveying pipeline, to take described air supply pipe and described gas distribution pipe communication port be that near-end helix arranges.When carrying out described air supply pipe, gas distribution pipe and described jet thrust ventilation bore selected, not only to make air-flow fluidised form in pipe suitable, to make described in each flow of jet thrust substantially equal simultaneously, here, select and adjust the method that described jet thrust goes out head piece footpath, the air extractor duct bore of described jet thrust is unequal, to leave described air supply pipe and described gas distribution pipe communication port apart from being as the criterion, nearest bore is minimum, and along with the increase of distance, bore becomes large, and bore is farthest maximum.
Against existing technologies, the beneficial effects of the utility model are:
When reaching the object that prevents Pneumatic conveying pipeline appearance obstruction, can reduce consumption of power, be conducive to energy-conservation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, and the A that Fig. 2 is Fig. 1 is to view.In figure: 1, conveying pipeline, 2, gas distribution pipe, 3, jet thrust, 4, air supply pipe.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model will be further described.
The utility model in the specific implementation, if be installed on parts or the elbow that comparison of resistance is large, should be loaded on the place ahead of parts or elbow, and meanwhile, the lead of screw of gas distribution pipe 2 can be smaller; This is because jet thrust 3, when work, can cause Yi Ge drainage district at its rear, presents partly step-down state; And in its place ahead, cause Yi Ge partial Pressure district; Like this, be conducive to reduce the pressure in parts or elbow, make the drainage of jet thrust 3 more concentrate in parts or elbow simultaneously.Same principle, if the utility model is to be installed on the conveying pipeline section of long distance, the central region that should be loaded on pipeline section is fully played the drainage of jet thrust 3 and pressurization.The head piece footpath that goes out of each jet thrust 3 can be definite according to design calculation.
