Description

Technical Field

[0001] The present invention relates to the technical field of suction guns, and particularly to a suction gun for an intake air adjustable vacuum conveyor. Background Art

[0002] The function of the suction gun is to enable the vacuum conveying system to feed smoothly, and the ratio of the intake air of the suction gun to the material can be adjusted by adjusting the position of the suction pipe of the suction gun in the outer pipe and the opening degree of the intake port, so as to facilitate the control of the material flow state.

[0003] The suction gun with adjustable intake air still has certain defects in actual use. Since the suction gun needs to be set above the open area to suck the material, the suction gun usually adopts two methods: manual operation or mechanical operation. However, due to various factors affecting the material, the internal adsorption force of the material increases, which often causes the material sucked by the suction gun to be intermittent or blocked. And affected by the external wet air flow, the material is affected by moisture and will form lumps on the inner wall of the suction gun, which is not conducive to the effective transportation of the material.

[0004] In view of this, a suction gun for an intake air adjustable vacuum conveyor is designed in the present invention to solve the above problems. Summary of the Invention

[0026] 1.

Finally, the material loosening mechanism can loosen the material due to shaking, and the loosened material can be actively scraped into by multiple impellers inside the material loosening mechanism, thus avoiding problems such as material suction stalling or muzzles being blocked due to excessive internal adsorption force of the material.

[0027] 2. By providing a heat-giving protection mechanism outside the material suction mechanism in the present invention, when the heat-giving protection mechanism continuously blows heat flow towards the gun body, finally the gun body will radiate heat energy towards its interior. As the air flow continuously conveys the material upward, the radiated heat energy can dehumidify and dry the air flow, and at the same time can also dry the material, thus avoiding the formation of lumps of the material after being affected by moisture and adhering to the inner wall of the suction gun, and further avoiding the appearance of contaminated areas on the inner wall of the suction gun.

[0028] 3. In the present invention, the driving mechanism is arranged on the outer gun barrel. As the support rod impacts the material gun at a high frequency, finally the impact frequency of the material gun and the shaking frequency caused by the air pressure will change. With the continuous input of the material, the material that has just entered the inside of the suction gun and is affected by moisture can be vibrated, and finally it will be quickly dried until it is pulverized under the blowing of the dry and high-temperature air flow.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0046] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0047] The following describes a suction gun for an intake air adjustable vacuum conveyor provided by some embodiments of the present invention with reference to the accompanying drawings.

[0048] Embodiment 1:

[0049] Combined with Figures 1 to 10As shown in the figure, a suction gun for an intake adjustable vacuum conveyor provided by the present invention includes a material suction mechanism 100, a heat-giving protection mechanism 200 arranged on the material suction mechanism 100, a material loosening mechanism 300 arranged at the bottom of the material suction mechanism 100, a stability enhancing component 400 arranged at the top of the material suction mechanism 100, and a driving mechanism 500 arranged on the heat-giving protection mechanism 200. The material suction mechanism 100 is used to provide a conveying channel for the material, the heat-giving protection mechanism 200 is used to provide heat radiation and protection for the material suction mechanism 100, the material loosening mechanism 300 is used to actively loosen the material and evenly suck it in, the stability enhancing component 400 is used to provide shock absorption protection for the material suction mechanism 100, and the driving mechanism 500 is used to knock and peel off the material in the material suction mechanism 100.

[0050] The material suction mechanism 100 includes a material gun 110, a top plate 150 arranged at the top of the material gun 110, two first sliders 160 installed at the bottom of the top plate 150, a conveying pipe 120 installed at the top end of the material gun 110, a ring gasket 130 installed at the bottom of the material gun 110, and two elastic reset components 140 installed on the ring gasket 130;

[0051] The elastic reset component 140 is composed of a mother pipe, a sub-rod, and a sub-spring;

[0052] The top plate 150 is composed of an annular gasket and a vertical pipe, and a cushion layer is arranged at the bottom of the annular gasket;

[0053] The stability enhancing component 400 includes a neck sleeve 420 arranged outside the two first sliders 160, a base 410 arranged at the bottom of the neck sleeve 420. Horizontal holes are opened on both sides of the base 410, and a limit end 430 is installed in the horizontal holes. A guide rod 440 is movably installed inside the limit end 430, and a stud 450 is installed on the threaded section of the guide rod 440;

[0054] The stud 450 is fixedly installed on the outer wall of the material gun 110;

[0055] A spring 460 is arranged outside the guide rod 440, and the inner end of the spring 460 bears on the stud 450, and the outer end of the spring 460 bears on the limit end 430;

[0056] The heat-giving protection mechanism 200 includes an outer gun barrel 210 arranged at the bottom of the base 410, a sleeve 240 arranged on the outer gun barrel 210, and a heat flow input pipe 250 installed inside the sleeve 240;

[0057] The material loosening mechanism 300 includes a bottom support 310 arranged at the bottom of the outer gun barrel 210, a cushion part 330 arranged at the bottom of the bottom support 310, and a bottom plate 340 arranged at the bottom of the cushion part 330;

[0059] When the conveying pipe 120 sucks air upward, the material gun 110 can introduce air flow through the gap between the cushion member 330 and the bottom plate 340. The introduced air flow will make the material approach the bottom plate 340. When the air flow pressure in the material gun 110 increases, the material gun 110 protected by the stability-enhancing assembly 400 can vibrate inside the outer gun barrel 210. Then, the vibrating bottom plate 340 can loosen the materials around it.

[0060] At the moment when the materials are loosened, the air flow can guide the loose materials to the grooves on the top of the bottom plate 340. Along with the air flow's push on the impellers 350, finally, the rotating impellers 350 can scrape the guided materials into the inner cavity of the material gun 110.

[0061] When the materials are continuously conveyed upward along the inner cavity of the material gun 110, the material gun 110 in the heat release state can dry the materials passing through its inner cavity.

[0064] Two symmetrically distributed sheaths 260 are installed on the inner wall of the outer gun barrel 210, and the outer ends of the sub-springs are adaptively clamped inside the sheaths 260.

[0065] The inner wall of the outer gun barrel 210 is provided with a heat insulation layer and a moisture-proof layer, and the outer wall of the outer gun barrel 210 is coated with an anti-rust paint layer.

[0066] Preferably, a wire can penetrate into the interior of the heat flow input pipe 250, and a heating coil can be wound around the outside of the material gun 110. When the coil is energized to release heat, the whole material gun 110 can be quickly heated up. According to the requirements of the heating efficiency of the material gun 110, the material of the material gun 110 can be selected according to actual needs.

[0067] When the material gun 110 is located in the middle of the inner cavity of the outer gun barrel 210 to convey materials, the material gun 110 vibrating due to the air flow in the middle of the inner cavity of the outer gun barrel 210 can provide a vibration platform for the materials during conveyance to prevent the materials from getting damp and caking on the inner wall of the material gun 110.

[0068] Embodiment 3:

[0069] Combined with Figure 10As shown, on the basis of Embodiment 1, the material loosening mechanism 300 further includes two second sliders 320 installed on the top of the cushion 330, and the second sliders 320 are movably installed in the sliding grooves at the bottom of the bottom bracket 310;

[0070] A transverse groove adapted to the constraint impeller 350 is provided at the bottom of the cushion 330;

[0071] The impeller 350 is composed of a shaft rod, a shaft head, and evenly distributed lengthened blades, and the shaft rod is installed in the hole inside the bottom plate 340 through a bearing.

[0072] Preferably, the bottom bracket 310, the cushion 330, and the bottom plate 340 are all made of stainless steel material, and the bottom plate 340 is fixed to the bottom of the cushion 330 by bolts or welding;

[0073] When the air flow passes through the gap between the bottom plate 340 and the cushion 330 and pushes the blades inside the multiple impellers 350 to rotate, the materials accumulated around the bottom plate 340 can be scraped in. Along with the high-frequency vibration of the bottom plate 340, the materials in the piled-up state can be shaken and loosened.

[0074] Embodiment 4:

[0075] Combined with Figures 3 to 9 As shown, in the above embodiment, the driving mechanism 500 includes a chassis 510 installed on the outer wall of the outer gun barrel 210 and two jigs 570;

[0076] A motor 520 is installed inside the chassis 510;

[0077] A crankshaft 530 is movably installed between the two jigs 570, a clamp seat 540 is movably installed on the crankshaft 530, and the other end of the clamp seat 540 is movably installed with a support rod 550;

[0078] A horizontally arranged bushing 560 is installed on the outer gun barrel 210, and the inner end of the support rod 550 is adapted to penetrate into the bushing 560;

[0079] A jack is provided at the top of the transmission shaft inside the motor 520, a plug rod is provided at the bottom of the crankshaft 530, and the plug rod is adapted to penetrate into the jack.

[0080] Preferably, the chassis 510 is fixedly installed on the outer wall of the outer gun barrel 210 by bolts, and a wire leading groove hole is provided inside the chassis 510, and the wire is connected to the connector of the motor 520 through the wire leading groove hole. When the wire is powered on, the motor 520 starts, and the driven crankshaft 530 will pull the clamp seat 540 and the support rod 550 to extend and retract reciprocally. Finally, the support rod 550 restricted by the bushing 560 can exert a higher-frequency impact force on the cushion 170, so as to ensure the appearance of double-frequency shock waves in the material gun 110, and further the materials passing through the inner cavity of the material gun 110 can be actively loosened.

[0081] Working principle and usage process of the present invention:

[0082] When the device is in use, as the material gun 110 and the conveying pipe 120 suck in air inwardly, the bottom support 310, the cushion 330 and the bottom plate 340 provided at the bottom of the material gun 110 can provide a passage for the input of materials. At this time, the high-pressure air flow will pass through a plurality of impellers 350, and the impellers 350 will be pressured to rotate. At the same time, the material gun 110 is located in the middle of the inner cavity of the outer gun barrel 210 and remains centered. Under the continuous high pressure, the material gun 110 will vibrate, and the vibration force will radiate to the bottom plate 340.

[0083] With the high-frequency jitter of the bottom plate 340 in the materials, the powdery or granular materials in the piled state can be loosened before being sucked in, so as to avoid the phenomenon of suspension or blockage during the suction of the materials into the inner cavity of the material gun 110.

[0084] When the dry heat flow is input into the gap between the material gun 110 and the outer gun barrel 210 through the heat flow input pipe 250, the whole material gun 110 will be continuously heated until the heat radiates into the air flow in the inner cavity of the material gun 110. The materials carried by the air flow and delivered upward along the inner cavity of the material gun 110 can be correspondingly dried, so as to avoid the influence of the air flow and the external humidity on the input of the materials, and further avoid the attachment of the caked materials to the wall of the material gun 110.

[0085] At the same time, with the start of the motor 520, the internal transmission shaft will drive the crankshaft 530 to rotate. The clamp seat 540 movably installed in the middle of the crankshaft 530 will then pull the support rod 550 to make reciprocating extensions. Finally, the support rod 550 will knock on the cushion 170 under the restraint of the bushing 560. The vibration frequency of the knock on the material gun 110 is higher than the vibration frequency brought by the wind pressure. Therefore, the materials passing through the inner cavity of the material gun 110 will get abnormal wave back vibration, which can avoid the phenomenon of caking and wall hanging of the materials, and at the same time ensure the constant material conveying amount.

[0086] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
