The positive pressure pneumatic conveyor has the advantages that uniform negative pressure regions are formed around the air outlet, so that the pressure difference between a feeding region at the edge of the air outlet and a pipe wall region of a conveying pipeline far away from the air outlet is not too large, the air blown out of the air outlet cannot flow back, and the feeding speed is greatly improved.

Description

正压气力输送器positive pressure pneumatic conveyor

技术领域 technical field

本发明涉及一种正压气力输送器。The invention relates to a positive pressure pneumatic conveyor.

背景技术 Background technique

参考图1和图2，现有的正压气力输送器，包括风机(图中未示出)、喂料斗2、输送管道3，风机的送风管4有一段进入输送管道内部给输送管道送风，喂料斗的下料口5开在输送管道上，风机送风管在输送管道的出风口6位于下料口的下方，风机送风管在输送管道的出风端口将所在位置输送管道划分为风机送风管的出风口和喂料斗的下料口，出风口和下料口的部分内沿与输送管道内壁重合。这种设计导致下料口转移到输送管道内壁，下料口的有效面积减少，位于出风口边缘的下料区域与远离出风口的下料口区域处在较大的压差，出风口吹出的风会反灌下料口，造成物料堵塞，下料不顺畅，并进一步影响输送速度。With reference to Fig. 1 and Fig. 2, existing positive pressure pneumatic conveyer comprises blower fan (not shown in the figure), feeding hopper 2, conveying pipe 3, and the air delivery pipe 4 of blower fan has a section to enter conveying pipe inside to send to conveying pipe. Wind, the feeding port 5 of the feeding hopper is opened on the conveying pipeline, the air supply pipe of the fan is located below the discharge port at the air outlet 6 of the conveying pipeline, and the air supply pipe of the fan divides the conveying pipeline at the position at the air outlet port of the conveying pipeline It is the air outlet of the fan air supply pipe and the discharge port of the feeding hopper, and the part of the inner edge of the air outlet and the discharge port coincides with the inner wall of the conveying pipe. This design leads to the transfer of the feeding port to the inner wall of the conveying pipe, and the effective area of the feeding port is reduced. The wind will backfill the feeding port, causing material blockage, unsmooth feeding, and further affecting the conveying speed.

发明内容 Contents of the invention

本发明的目的在于提供一种能提升送料能力的正压气力输送器。The purpose of the present invention is to provide a positive pressure pneumatic conveyor capable of improving the feeding capacity.

本发明提供的正压气力输送器，包括风机、喂料斗、输送管道，风机的送风管有一段进入输送管道内部给输送管道送风，喂料斗的下料口开在输送管道上，风机送风管在输送管道的出风口位于下料口的下方，其特征在于：风机送风管在输送管道的出风端口外沿与输送管道壁均有间隙，喂料斗的下料口开在输送管道的管壁上。The positive pressure pneumatic conveyor provided by the present invention includes a fan, a feeding hopper, and a conveying pipeline. A section of the air supply pipe of the fan enters the interior of the conveying pipeline to supply air to the conveying pipeline, and the feeding port of the feeding hopper is opened on the conveying pipeline. The air duct is located below the discharge port at the air outlet of the conveying pipeline. It is characterized in that: there is a gap between the air supply pipe of the fan and the wall of the conveying pipeline on the outer edge of the air outlet port of the conveying pipeline, and the discharge port of the feeding hopper is opened in the conveying pipeline. on the tube wall.

上述风机送风管呈喇叭形，出风口位于喇叭形送风管的收缩端。The air supply pipe of the above-mentioned fan is trumpet-shaped, and the air outlet is located at the contracting end of the trumpet-shaped air supply pipe.

上述送风管的出风口处在输送管道的中间位置。The air outlet of the air supply pipe is located in the middle of the conveying pipe.

本发明的正压气力输送器的优点在于：由于风机送风管在输送管道的出风口位于下料口的下方，风机送风管在输送管道的出风端口外沿与输送管道壁均有间隙，喂料斗的下料口开在输送管道的管壁上，这样在出风口的周围均形成均匀的负压区，使位于出风口边缘的送料区域与远离出风口的输送管道的管壁区域压差不至于太大，使从出风口吹出的风不会反灌，大大提高了送料速度。The advantage of the positive pressure pneumatic conveyor of the present invention is that since the air supply pipe of the fan is located below the discharge port at the air outlet of the conveying pipeline, there is a gap between the air supply pipe of the fan and the wall of the conveying pipeline at the outer edge of the air outlet port of the conveying pipeline , the feeding opening of the feeding hopper is opened on the pipe wall of the conveying pipe, so that a uniform negative pressure area is formed around the air outlet, so that the feeding area on the edge of the air outlet and the pipe wall area of the conveying pipe far away from the air outlet are under pressure. The difference is not too large, so that the wind blown from the air outlet will not flow back, and the feeding speed is greatly improved.
