Description

Technical Field

[0001] This utility model relates to the field of pipeline conveyor technology, specifically a pneumatic pipeline conveyor. Background Technology

[0002] Screw conveyors (also known as spiral conveyors) are key equipment in grain storage, processing, and transfer. They are driven by a motor to rotate spiral blades (mostly made of manganese steel, which is wear-resistant and suitable for granular materials). The spiral thrust of the blades is used to transport granular grains such as corn, wheat, and rice along a closed conveying pipe (or hose). They have the advantages of compact structure, small footprint, and the ability to achieve horizontal / inclined / vertical multi-directional conveying. They are widely used in scenarios such as grain depot discharge, raw material transfer in flour mills, and mobile grain loading and unloading on vehicles.

[0003] Currently, most mainstream auger conveyors use electric motors as their power source (usually three-phase asynchronous motors with a power of 1.5-22kW to suit different conveying requirements). However, in grain processing environments with strict explosion-proof requirements, motor-driven systems present unavoidable safety risks and technical limitations. During daily use, dust generated by electric sparks or high temperatures on the surface of the motor during operation can significantly increase the danger of operation. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic pipeline conveyor to solve the problem mentioned in the background art that the motor is prone to explosion due to temperature and sparks during operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic pipeline conveyor, comprising a discharge shell, the outer surface of which is inclined, and an installation docking shell is inserted into one side of the discharge shell. A conveying hose is inserted into the end of the discharge shell away from the installation docking shell, and a connector fixing bracket is inserted into the end of the conveying hose away from the discharge shell. Clamps are fixedly installed at both ends of the conveying hose. A hollow spiral blade is rotatably installed inside the conveying hose, and the outer surface of the hollow spiral blade is in contact with the outer surface of the conveying hose. An air motor is fixedly installed inside the installation docking shell, and the output end of the air motor penetrates through the outer surface of the installation docking shell. A plug cap is fixedly installed at the output end of the air motor.

[0006] Preferably, an adapter is rotatably installed inside the discharge shell, and another adapter is rotatably installed inside the connector fixing frame. An elbow nut assembly is inserted and installed on the outer surface of the adapter, and the elbow nut assembly is connected to the hollow spiral blade. Bearings are provided between the adapter and the discharge shell and the connector fixing frame respectively. The hollow spiral blade and the connector fixing frame are concentrically designed, and the hollow spiral blade and the conveying hose are concentrically designed.

[0007] By adopting the above technical solution, the two ends of the hollow spiral blade can be easily fixed by the adapter and elbow nut assembly, allowing the hollow spiral blade to rotate stably inside the conveying hose. It is also convenient to replace the conveying hose and hollow spiral blade after they wear and break. Furthermore, the bearing can make the adapter and hollow spiral blade rotate more smoothly.

[0008] Preferably, a countersunk mounting screw is installed through the outer surface of the mounting dock shell, and the countersunk mounting screw is threadedly connected to the unloading shell. A spline connector is fixedly installed on the outer surface of one end of the adapter inside the unloading shell, and one end of the spline connector is inserted into the plug cap.

[0009] By adopting the above technical solution, the blanking shell and the mounting shell are connected and installed by countersunk screws, and there are no obstructions on the outer surface of the mounting shell that could cause bumps or obstructions. Furthermore, the blanking shell and the mounting shell can be easily disassembled and separated for maintenance through the insertion of spline connectors and plug caps.

[0010] Preferably, an airflow regulating valve is fixedly installed inside the mounting housing near the air motor, and the outer surface of the airflow regulating valve penetrates the outer surface of the mounting housing, with one end of the airflow regulating valve connected to the air motor.

[0011] By adopting the above technical solution, the flow rate of air entering the air motor can be adjusted by the airflow regulating valve, thereby adjusting the rotation speed of the air motor and allowing the conveying speed of the pipeline conveyor to be adjusted.

[0012] Preferably, a quick-connect plug is installed through the side surface of the mounting housing, and the quick-connect plug is threadedly connected to the airflow regulating valve. The quick-connect plug is connected to the pipeline of an external air source.

[0013] By adopting the above technical solution, it is possible to effectively connect and fix the pipes through quick-connect plugs, which facilitates the quick connection and disconnection of the pipes. Furthermore, the external gas source device is set away from the material conveying location, which can further reduce the probability of ignition damage caused by sparks.

[0014] Preferably, one end of the air motor penetrates the outer surface of the mounting dock housing, a jet head is inserted into the inside of the connector fixing bracket, and the jet head and the connector fixing bracket are fixed by a set screw. The jet head and the connector fixing bracket are concentrically designed, and the outer surface of the jet head does not contact the outer surface of the adapter. A connecting hose is inserted between the mounting dock housing and the jet head, and a cable tie is provided between the connecting hose and the delivery hose.

[0015] Using the above technical solution, the jet head can be easily installed and fixed using the set screw, preventing it from contacting the adapter and causing damage. The air discharged from the air motor can be delivered into the jet head via a connecting hose. Combined with the air ejected from the jet head and the rotation of the hollow spiral blades, materials can more easily enter the conveying hose for transport. Furthermore, the connecting hose can be secured to the conveying hose with cable ties, preventing it from moving arbitrarily during use and allowing materials to enter and move more easily within the conveying hose.

[0016] Preferably, a pointed tip is inserted into the inside of the connector fixing frame, and the outer surface of the pointed tip is penetrated by an adapter inside the connector fixing frame. The adapter and the pointed tip are fixed together by a set screw, and a lever plate is evenly fixedly installed on the outer surface of the pointed tip.

[0017] By adopting the above technical solution, the tip and the adapter can be easily installed and separated by the set screw, making it easy to replace the tip after it wears out. At the same time, the rotation of the adapter can drive the tip and the push plate to rotate, allowing the push plate to push the material, making it easier for the surrounding material to flow to the connector fixing frame, and allowing the material to slide continuously to the connector fixing frame, greatly improving the efficiency of material conveying.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This pneumatic pipeline conveyor:

[0019] 1. During use, air can be supplied to the air motor through an external air source device. The air motor drives the adapter and the hollow spiral blade to rotate together, allowing the material to be transported through the rotation of the hollow spiral blade and the restriction of the conveying hose. This greatly reduces the risk of explosion caused by the power end being a motor and greatly improves the explosion-proof performance of the pipeline conveyor.

[0020] 2. When the air motor malfunctions, the countersunk mounting screws can be removed to separate and disassemble the mounting housing and the unloading housing, and the spline connector and the plug cap can be separated. This allows the mounting housing to be removed for easy repair and replacement of parts, greatly improving the convenience of maintenance.

[0021] 3. The amount of air fed into the air motor can be adjusted by rotating the airflow regulating valve, which in turn adjusts the rotation speed of the adapter. This adjusts the rotation speed of the hollow spiral blade inside the conveying hose. The gas discharged from the air motor can then be discharged into the jet nozzle through the connecting hose. The gas discharged from the jet nozzle can then assist in conveying the material into the conveying hose, greatly improving the conveying efficiency of the conveying hose.

[0022] 4. After the connector fixing frame is inserted into the material, the tip will rotate along with the rotation of the hollow spiral blade and the adapter, causing the tip to rotate and drive the dial plate to rotate. After the material is sucked into the conveying hose, the dial plate can agitate the material and allow it to slide down to the connector fixing frame, ensuring the continuous conveying of the pipeline conveyor.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6This utility model provides a technical solution: a pneumatic pipeline conveyor, including a discharge shell 1, the outer surface of which is inclined, and a mounting docking shell 5 is inserted and installed on one side of the discharge shell 1. A quick-connect plug 13 is installed through the side surface of the mounting docking shell 5, and the quick-connect plug 13 is threadedly connected to the airflow regulating valve 12. The quick-connect plug 13 is connected to a pipeline of an external air source. A conveying hose 2 is inserted and installed at the end of the discharge shell 1 away from the mounting docking shell 5, and a connector fixing bracket 4 is inserted and installed at the end of the conveying hose 2 away from the discharge shell 1. The discharge shell 1 is rotatably mounted inside. There is an adapter 7, and another adapter 7 is rotatably installed inside the connector fixing frame 4. An elbow nut assembly 8 is inserted and installed on the outer surface of the adapter 7, and the elbow nut assembly 8 is connected to the hollow spiral blade 6. Bearings are provided between the adapter 7 and the discharge shell 1 and the connector fixing frame 4 respectively. The hollow spiral blade 6 and the connector fixing frame 4 are concentrically designed. The hollow spiral blade 6 and the conveying hose 2 are concentrically designed. The two ends of the conveying hose 2 are fixedly installed with clamps 3. The hollow spiral blade 6 is rotatably installed inside the conveying hose 2, and the outer surface of the hollow spiral blade 6 is in contact with the outer surface of the conveying hose 2.

[0032] Firstly, during use, simply connect the quick-connect plug 13 to the external air source pipeline to allow external gas to be supplied into the air motor 10. The rotation of the air motor 10 drives the plug cap 11 to rotate, causing the spline connector 9, which is plugged into the plug cap 11, to rotate as well. This drives the adapter 7, and the hollow spiral blade 6, which is connected to the elbow nut assembly 8 and the adapter 7, can rotate. This allows the connector fixing frame 4, which is inserted into the material, to transport and move the material through the rotation of the hollow spiral blade 6 and the restriction of the conveying hose 2. The material can then be discharged through the discharge shell 1 into the container to be transported. This allows the pipeline conveyor to transport materials using only gas, greatly reducing the possibility of explosion and significantly improving the explosion-proof performance of the pipeline conveyor.

[0033] An air motor 10 is fixedly installed inside the mounting docking shell 5, and the output end of the air motor 10 passes through the outer surface of the mounting docking shell 5. A plug cap 11 is fixedly installed at the output end of the air motor 10. An airflow regulating valve 12 is fixedly installed inside the mounting docking shell 5 near the air motor 10, and the outer surface of the airflow regulating valve 12 passes through the outer surface of the mounting docking shell 5. One end of the airflow regulating valve 12 is connected to the air motor 10. A countersunk mounting screw 15 is installed through the outer surface of the mounting docking shell 5, and the countersunk mounting screw 15 is threadedly connected to the unloading shell 1. A spline connector 9 is fixedly installed on the outer surface of one end of the adapter 7 inside the unloading shell 1, and one end of the spline connector 9 is plugged into the plug cap 11.

[0034] Secondly, the use of the plug cap 11 and countersunk mounting screw 15 greatly facilitates the separation of the material discharge shell 1 and the mounting docking shell 5. When the components inside the mounting docking shell 5 are damaged, the countersunk mounting screw 15 can be removed to separate the material discharge shell 1 and the mounting docking shell 5. It is also convenient to disassemble the elbow nut assembly 8, separate the hollow spiral blade 6, and install and fix the conveying hose 2 through the clamp 3. This facilitates disassembly, separation, inspection, and replacement of parts. At the same time, the air intake of the air motor 10 can be adjusted through the airflow regulating valve 12, which makes it convenient to adjust the speed according to different types of conveyed materials, greatly improving the practicality and ease of maintenance of the pipeline conveyor.

[0035] One end of the air motor 10 penetrates the outer surface of the mounting docking housing 5. A jet head 16 is inserted into the inside of the connector fixing bracket 4 and is fixed to the connector fixing bracket 4 with a set screw. The jet head 16 and the connector fixing bracket 4 are concentrically designed. A pointed head 17 is inserted into the inside of the connector fixing bracket 4 and is penetrated by the adapter 7 inside the connector fixing bracket 4. The adapter 7 and the pointed head 17 are fixed with a set screw. The outer surface of the pointed head 17 is evenly fixed with a baffle plate 18. The outer surface of the jet head 16 does not contact the outer surface of the adapter 7. A connecting hose 14 is inserted between the mounting docking housing 5 and the jet head 16 and is connected to the delivery hose 2 with a cable tie.

[0036] Furthermore, when the air motor 10 runs out of gas, it will be discharged outward and enter the interior of the connecting hose 14. Finally, it will enter the interior of the jet head 16 through the connecting hose 14. The jet head 16 will spray out the gas, allowing the material to enter the interior of the joint fixing frame 4. The sprayed gas can assist in conveying the material into the conveying hose 2. The rotation of the hollow spiral blade 6 and the adapter 7 can drive the tip 17 to rotate, and the deflector 18 can deflect the material flow to the joint fixing frame 4, filling the gaps after the material is conveyed. This allows the material to enter the conveying hose 2 evenly, greatly improving the feeding efficiency of the pipeline conveyor.

[0037] Working principle: In use, simply insert the connector fixing bracket 4 into the material, and then connect the external air source pipe to the air motor 10 through the quick connector 13. Then, adjust the air supply of the airflow regulating valve 12 according to the type of material being conveyed, so that the plug cap 11 can rotate together with the spline connector 9, thereby driving the hollow spiral blade 6 to rotate inside the conveying hose 2. The air sprayed by the air motor 10 is collected through the connecting hose 14 and discharged into the jet nozzle 16 and sprayed outward. The material is propelled by the gas through the jet nozzle 16. At the same time, the rotation of the tip 17 and the deflector 18 causes the material to be drawn away, and the surrounding material can gather towards the connector fixing bracket 4. With the blowing of gas, the material can fall more easily onto the connector fixing bracket 4, which greatly improves the conveying quality and explosion-proof performance of the pipeline conveyor.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
