Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pneumatic material conveying equipment, specifically to a pneumatic conveying pipeline and a large-drop pneumatic conveying system. Background Technology
[0002] Pneumatic conveying equipment generally consists of receivers such as throats, nozzles, and transmitters, conveying pipes, air ducts, separators, airlocks, dust collectors, and fans. Based on their operating pressure, pneumatic conveying equipment can be divided into two main categories: suction conveying and pressure conveying.
[0003] For pneumatic conveying equipment with large drops, several horizontally placed pipe sections will be left during the laying of the conveying pipeline. Inside the horizontally placed pipe sections, some material will accumulate at the bottom of the pipeline, which will affect the normal conveying of materials.
[0004] In the prior art, as shown in the patent document with authorization announcement number CN221026369U, a pneumatic conveying pipeline includes a horizontal pipeline, both ends of which are rotatably connected to connecting pipes. Support plates are fixedly connected to the lower sides of both connecting pipes. A drive assembly for rotating the horizontal pipeline is fixedly installed on the side wall of one of the support plates. A flow-limiting structure for driving the movement of powder is provided on the inner wall of the horizontal pipeline.
[0005] In use, the connecting pipe and horizontal pipe are fixed in position by the support plate, and the connecting pipe is connected to the pipes at both ends. When the powder is conveyed into the horizontal pipe, under the action of the flow-limiting structure, a part of the powder is blocked to the lower side of the horizontal pipe. Then, the control drive component drives the horizontal pipe to rotate. Under the action of the flow-limiting structure, the blocked powder is mixed into the powder being conveyed again as the horizontal pipe rotates, thus avoiding accumulation.
[0006] It requires a separate drive component to rotate the horizontal pipe, which undoubtedly increases the production and operating costs of the equipment. Utility Model Content
[0007] The main inventive concept of this application is to prevent material from accumulating at the bottom of the horizontal pipeline by agitating and blowing the material at the bottom of the horizontal pipeline without increasing costs. This solves the problem of material accumulation in a relatively convenient way, without requiring additional drive components to drive the horizontal pipeline to rotate.
[0008] Therefore, the first aspect of this application provides a pneumatic conveying pipeline, including a plurality of lifting pipelines and a horizontal pipeline connected between the lifting pipelines, an airflow reversing mechanism is provided at the connection between the feed end of the lifting pipeline and the horizontal pipeline, a pushing mechanism is provided at the bottom of the horizontal pipeline, and the airflow reversing mechanism is connected to the pushing mechanism.
[0009] By adopting the above technical solution: the airflow reversing mechanism can collect part of the airflow at the end of the lifting pipeline and then redirect it to the pushing mechanism at the bottom of the horizontal pipeline. The pushing mechanism then sprays the material out from the bottom of the horizontal pipeline again, disturbing and pushing the material at the bottom of the horizontal pipeline, preventing the material from accumulating at the bottom of the horizontal pipeline, and facilitating the long-distance material transportation with large drops.
[0010] As an optional technical solution of this application, the airflow reversing mechanism includes an air collection component disposed at the feed end of the lifting pipeline and the horizontal pipeline, and a pressurizing component connected to the air collection component.
[0011] By adopting the above technical solution: the air collection component can collect part of the airflow at the end of the lifting pipeline, and then the airflow is pressurized by the pressurization component and delivered to the pushing mechanism, which sprays out disturbance and pushes the material.

[0013] As an optional technical solution of this application, the pressurization component includes a pressurization hood that is connected to the gas collection hood. The large-diameter end of the pressurization hood is connected to the gas collection hood, and the small-diameter end of the gas collection hood is connected to the pushing mechanism through an air supply pipe.
[0014] By adopting the above technical solution: by setting up filter elements, materials can be blocked from entering the gas collection hood. After the airflow enters the gas collection hood through the filter elements, it is pressurized by the pressure booster and then transported to the pushing mechanism through the connecting pipe.
[0015] As an optional technical solution of this application, the pushing mechanism includes a gas distribution chamber disposed on the lower side of the horizontal pipeline, the gas distribution chamber being connected to the gas delivery pipe, and the gas distribution chamber being connected to the bottom of the horizontal pipeline through multiple branch pipes.
[0016] By adopting the above technical solution: gas enters the gas distribution chamber through the connecting pipe, and then enters the bottom of the horizontal pipeline through the branch pipe, disturbing and pushing the material at the bottom to prevent material accumulation.
[0017] As an optional technical solution of this application, the branch pipe is inclined between the gas distribution chamber and the horizontal pipeline, and its inclination direction is in the same direction as the material conveying direction.
[0018] By adopting the above technical solution, the inclined branch pipe can blow the airflow obliquely into the horizontal pipe, while following the material conveying direction, which is convenient for disturbing and blowing the material.
[0019] As an optional technical solution of this application, the interior of the horizontal pipeline is provided with an elastic baffle, which is located at the outlet port of the branch pipe.
[0020] As an optional technical solution of this application, the elastic bleed guide plate has a curved section, and the inner arc of the curved section faces the air outlet port of the branch pipe.
[0021] By adopting the above technical solution, when the airflow is ejected from the branch pipe, it can drive the elastic material guide plate to vibrate, disturbing the material at the bottom of the horizontal pipeline. At the same time, the airflow can also assist in blowing the material.
[0022] As an optional technical solution of this application, the air delivery pipe is equipped with a pulse solenoid valve.
[0023] By adopting the above technical solution, a pulse airflow can be generated by setting a pulse solenoid valve to push the material at the bottom of the horizontal pipeline.
[0024] The second aspect of this application provides a large-drop pneumatic conveying system, including a blower, a feeder, and a discharger, and also includes the aforementioned pneumatic conveying pipeline connected between the feeder and the discharger.
[0025] By adopting the above technical solution, it is possible to adapt to the pneumatic conveying of materials over long distances and with large drops.
[0026] The working principle and beneficial effects of this application are as follows:
[0027] 1. In this application, the airflow reversing mechanism can collect part of the airflow at the end of the lifting pipeline and then redirect it to the pushing mechanism at the bottom of the horizontal pipeline. The pushing mechanism then sprays the material out from the bottom of the horizontal pipeline again, disturbing and pushing the material at the bottom of the horizontal pipeline, preventing the material from accumulating at the bottom of the horizontal pipeline, and facilitating the long-distance material transportation with large drop.
[0028] 2. Gas enters the gas distribution chamber through the connecting pipe, and then enters the bottom of the horizontal pipeline through the branch pipe, disturbing and pushing the material at the bottom to prevent material accumulation.
[0029] 3. When the airflow is ejected from the branch pipe, it can drive the elastic material guide plate to vibrate, disturbing the material at the bottom of the horizontal pipe. At the same time, the airflow can also assist in blowing the material. Attached Figure Description

[0040] The basic principle of this embodiment is as follows: the airflow reversing mechanism 300 can collect part of the airflow at the end of the lifting pipe 100 and then reversing it to the pushing mechanism 400 at the bottom of the horizontal pipe 200.
