Abstract
The utility model relates to the technical field of pneumatic conveying devices, in particular to a pneumatic conveying pipeline blowing and blocking device, which comprises an outer barrel body, wherein an inner cavity is sleeved inside the outer barrel body, and flanges are fixedly connected with the two integral sides of the inner cavity and the outer barrel body; the upper end of the outer cylinder body is provided with an air inlet which is positioned at the total length 1/3 of the outer cylinder body. After the structure of the oil adding device is adopted, the utility model discloses a stifled device is blown to pneumatic conveying pipeline can additionally provide atmospheric pressure in each section of pipeline when remote pipe-line transportation, can prevent that fan pressure is not enough to lead to unable smooth transportation, and the phenomenon of jam appears in the effectual conveying pipeline material of abolishing.
Description
Technical Field
The utility model relates to a pneumatic conveyor technical field, especially a pneumatic conveying pipeline blows stifled device.
Background
The pneumatic conveying system provides power source through a conveying fan or an air compressor, and the air with certain speed drives the materials to move. In the present pipeline pneumatic conveying process, because the conveying distance is too long, the aerodynamic force is not enough, the material property is special, and the like, the material cannot be normally conveyed, or the conditions of material blockage, pipe blockage and the like are generated.
The utility model discloses a 201420160018.3 of china utility model, a pneumatic conveyor blows stifled device, including storage silo, push away the material pipe, blow stifled mechanism, actuating mechanism and landing leg, push away the material pipe setting on the lateral wall of storage silo and communicate with the storage silo inner chamber, the storage silo is equipped with the relative one side of pushing away the material pipe and blows stifled mechanism, it passes through the ventilation pipe and is connected with compressed air source to blow stifled mechanism, the pushing away material pipe promotes through the strength of blowing stifled mechanism and realizes the pay-off and clear stifled, it contains nozzle and removal trachea to blow stifled mechanism, the nozzle is the back-off awl form, and its tapering is the same with pushing away the tapering section tapering of material pipe contraction.
Disclosure of Invention
The utility model aims to solve the technical problem that a pneumatic conveying pipeline that can effectively avoid the pneumatic conveying putty condition blows stifled device is provided.
In order to solve the technical problem, the pneumatic conveying pipeline blowing and blocking device comprises an outer barrel, wherein an inner cavity is sleeved inside the outer barrel, and flanges are fixedly connected to the two integral sides of the inner cavity and the outer barrel; the upper end of the outer cylinder body is provided with an air inlet which is positioned at the total length 1/3 of the outer cylinder body.
Preferably, the air inlet is used as an inner and outer screw connection screw hole.
Preferably, the inner cavity is provided with pressurizing holes distributed circumferentially, and the included angle between the direction of the pressurizing holes and the central axis of the inner cavity is an acute angle.
Preferably, the position of the pressurizing hole is arranged at the position of the total length 1/3 of the inner cavity body and opposite to the direction of the air inlet of the outer cylinder body.
After the structure of the oil adding device is adopted, the utility model discloses a stifled device is blown to pneumatic conveying pipeline can additionally provide atmospheric pressure in each section of pipeline when remote pipe-line transportation, can prevent that fan pressure is not enough to lead to unable smooth transportation, and the phenomenon of jam appears in the effectual conveying pipeline material of abolishing.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic three-dimensional structure diagram of the pneumatic conveying pipeline blockage blowing device of the present invention.
Fig. 2 is a sectional view of the pneumatic conveying pipeline blockage blowing device of the utility model.
In the figure: 1 is an outer cylinder body, 2 is an inner cavity body, 3 is a connecting flange, and 4 is an air inlet.
Detailed Description
As shown in fig. 1 and 2, the utility model discloses a pneumatic conveying pipeline blows stifled device, including outer barrel 1, the inside cover of outer barrel 1 has interior cavity 2, the whole both sides fixedly connected with flange 3 of interior cavity 2 and outer barrel 1 makes things convenient for the connection of pipeline to use simultaneously. The upper end of the outer cylinder body 1 is provided with an air inlet 4, the air inlet 4 is positioned at the total length 1/3 of the outer cylinder body 1, and the air inlet 4 is used as an inner and outer screw connection screw hole.
As shown in fig. 2, the inner cavity 2 is provided with pressurizing holes distributed circumferentially, and the direction of the pressurizing holes forms an acute angle with the central axis of the inner cavity 2. Therefore, the blowing and blocking device is guaranteed to be opened, pressurized gas can provide pressure along the material conveying direction after entering the cavity, and the counter-flow phenomenon cannot be generated. Therefore, when the pressure is insufficient or the pipe is blocked in the material conveying process, the problems of conveying unsmooth and pipeline blockage can be smoothly solved by providing extra pressure from the supercharger.
As shown in fig. 2, the pressurizing hole is located at 1/3 of the total length of the inner chamber 2 and opposite to the direction of the air inlet 4 of the outer cylinder 1. Can additionally provide atmospheric pressure in each section of pipeline when remote pipe-line transportation like this, can prevent that fan pressure is not enough to lead to unable smooth transportation, the phenomenon of jam appears in the effectual pipeline material of abolishing.
Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
