Description

Technical Field

[0001] The utility model relates to the field of dust material transportation, in particular to a fully enclosed automatic dust feeding device. Background Art

[0002] Vacuum loader, also known as vacuum conveyor, is a dust-free closed pipeline conveying equipment that uses vacuum suction to transport granular and powdered materials. It uses the air pressure difference between the vacuum and the ambient space to form gas flow in the pipeline, drive the movement of powdered materials, and thus complete the transportation of powders.

[0003] The vacuum loader consists of a vacuum pump (oil-free, water-free), a membrane filter bag filter, a compressed air backblowing device, a pneumatic discharge door device, a vacuum hopper, a stainless steel adjustable suction gun, a conveying hose and other components. Usually, the staff puts the suction gun into the raw material barrel, and under the action of the vacuum pump, the powder material is sucked and transferred to the finished product packaging bag.

[0004] The suction gun is a large-caliber suction gun, and its suction force is greater the closer it is to the nozzle. When the worker places the suction gun in the raw material barrel, the suction gun can suck out most of the materials in the barrel. Because the suction gun is hung on the upper edge of the outer wall of one side of the raw material barrel by a hook, some corners in the barrel are not easy to be sucked clean. It is necessary to manually hold the suction gun and constantly change the position, and adjust the angle of the suction gun nozzle to suck the raw material barrel clean. The suction gun not only has a large diameter but also has a certain weight. The worker needs to hold it with both hands to effectively change the angle of the suction gun. In actual production, it lacks convenience and brings trouble to the workers' labor. Utility Model Content

A fixing device 12 is movably installed on the outside of the sleeve 8. By setting the limiting grooves 9, the sleeve 8 can be installed inside the fixing device 12, and the fixing device 12 includes a mounting frame 1201, and a telescopic component 1204 is rotatably connected to the side of the mounting frame 1201, and the other end of the telescopic component 1204 is rotatably connected to The clamping assembly 1205 is provided with a fixing device 12, and a suction gun 7 can be movably installed inside the fixing device 12, so that the suction gun 7 can be fixed at the middle position of the upper edge of the barrel wall for holding materials through the fixing device 12, and then the suction gun 7 can evenly suck the raw materials in the material barrel when working. If the suction gun 7 is hung on one side of the material barrel by a hook, the problem of unclean suction of the material in the material barrel will occur. By clamping the suction gun 7 by the fixing device 12, the material can be evenly sucked, and then the material can be sucked more thoroughly, reducing the number of times the angle of the suction gun 7 is manually adjusted, thereby reducing the workload of workers.

[0033] See also Figure 4 There are three groups of telescopic components 1204, and the ends of the three groups of telescopic components 1204 are rotatably connected to the clamping components 1205. By setting three groups of telescopic components 1204, the fixing device 12 can be clamped on the outer wall edge of the material barrel more stably.

[0034] See also Figure 4The telescopic component 1204 is composed of a telescopic sleeve and a telescopic rod. The length of the telescopic component 1204 is manually adjusted. By setting the telescopic component 1204, the telescopic component 1204 is composed of a telescopic sleeve and a telescopic rod. The length can be freely adjusted to facilitate the fixing device 12 to clamp and fix on material barrels of different diameters.

[0035] See also Figure 4 The clamping assembly 1205 is composed of two groups of rotatably connected clamping plates, and a torsion spring is arranged inside the clamping assembly 1205. By arranging the clamping assembly 1205, the fixing device 12 can be fixed on the outer wall of the material barrel.

[0036] See also Figure 3 A knob 10 is threadedly connected to one side of the sleeve 8, and the knob 10 passes through the interior of the sleeve 8, and the end of the knob 10 is rotatably connected to an extrusion block 11. By setting the sleeve 8 and the knob 10 to be threadedly connected, the knob 10 can be rotated to push the extrusion block 11, thereby fixing the sleeve 8 on the surface of the suction gun 7.

[0037] See also Figure 1 A negative pressure fan 2 is arranged on the top of the mobile vehicle 1, and a barrel 3 is installed on one side of the mobile vehicle 1, and the barrel 3 and the mobile vehicle 1 are connected by a connecting pipe 4. By arranging the negative pressure fan 2, negative pressure power can be provided for the barrel 3.

[0038] See also Figure 1 A back-blowing air bag 5 is installed at the top of the barrel 3 , and a snail flip valve 6 is installed at the bottom of the barrel 3 . By setting the back-blowing air bag 5 , the material sucked into the barrel 3 can be blown into the bottom of the barrel 3 . Embodiment 2

[0039] A fully enclosed dust automatic feeding device, such as Figure 4 As shown, the inner part of the mounting frame 1201 is rotatably connected to the inner ring 1202, and the inner side of the inner ring 1202 is provided with a limiting rod 1203 matching the limiting groove 9. By providing a rotatable inner ring 1202 on the inner side of the fixing device 12, when the suction gun 7 is movably installed on the inner ring 1202 by installing the snap-fit ​​sleeve 8, the suction gun 7 can freely rotate 360 ​​degrees in the plane and rotate a certain angle in the vertical direction. That is, the arrangement of the inner ring 1202 and the sleeve 8 allows the worker to easily adjust the angle of the suction gun 7 so as to more thoroughly suck the position of the bottom edge of the material barrel.

[0040] The working principle of the utility model is as follows: when using a vacuum loader to load materials, first adjust the telescopic component 1204 of the fixing device 12 to an appropriate length, and then use three sets of clamping components 1205 to clamp and fix it on the upper edge of the outer wall of the material barrel, and then according to the depth of the material barrel, put the sleeve 8 on the outside of the suction gun 7, turn the knob 10, and use the threaded connection between the knob 10 and the outer wall of the sleeve 8 so that the knob 10 can push the extrusion block 11 to squeeze the outer wall of the sleeve 8, thereby fixing the sleeve 8 on the outside of the suction gun 7, and then pass the suction gun 7 through the inner ring 1202 of the fixing device 12, so that the limiting grooves 9 on both sides of the sleeve 8 are engaged with the limiting rod 1203 on the inner side of the inner ring 1202. At this step, the suction gun 7 is installed on the material barrel through the fixing device 12.

[0041] Start the negative pressure fan 2 to form a pressure difference inside the barrel 3 through the connecting pipe 4, so that the suction gun 7 has a suction pressure. In the process of the suction gun 7 sucking the material, the back-blowing air bag 5 works to blow the material to the bottom of the barrel 3. The worker can manually rotate the suction gun 7. The sleeve 8 is located on the limit rod 1203 and rotates so that the suction gun 7 can be adjusted to a certain angle in the vertical direction, so that the nozzle of the suction gun 7 is aligned with the edge of the bottom of the material barrel for suction, which can suck the material more cleanly. The inner ring 1202 can be rotated so that the suction gun 7 can adjust the angle along the radial direction all the way. The worker uses the fixing device 12 to adjust the angle of the suction gun 7 more easily and conveniently, which also makes the suction effect of the suction gun 7 better.

[0042] When the barrel 3 is filled with the material sucked in by the suction gun 7, the snail flip valve 6 can be started to release the material, and the released material can be packed in a plastic woven bag.
