Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, and in particular relates to a PTA tanker feeding device. Background Technology

[0002] A PTA tanker truck is a vehicle specifically designed for transporting PTA (purified terephthalic acid). PTA is an important organic raw material, primarily used in the production of polyester fibers, polyester chips, and polyester films.

[0003] When feeding PTA tank trucks, a feeding device is required. Most existing feeding devices are funnel-shaped. Because their diameter gradually decreases from top to bottom, the material flow channel becomes smaller and smaller. Since the material from the top keeps entering the funnel, it is easy for the material to accumulate and block the bottom of the funnel, resulting in slow feeding efficiency and affecting work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a PTA tanker truck feeding device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A PTA tanker feeding device includes a feeding hopper, a discharge pipe connected to the bottom of the feeding hopper, an air blowing mechanism for conveying airflow to the inner cavity of the discharge pipe is provided on the side wall of the discharge pipe, a valve cover is provided at the bottom of the discharge pipe, and a drive mechanism for controlling the opening or closing of the valve cover is provided on the feeding hopper.

[0006] Preferably, the air blowing mechanism includes an air pump and multiple diverter pipes. The multiple diverter pipes are arranged in a circumferential array on the side wall of the feed pipe, and each diverter pipe has an air outlet extending into the feed pipe at both ends of its side wall. The multiple diverter pipes are connected by connecting pipes, and the air pump is connected to one of the connecting pipes through a conduit.

[0007] Preferably, the air pump is fixed to the side wall of the feed pipe by a bracket.

[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a PTA tanker loading device.

[0025] like Figure 1-3 As shown, this utility model discloses a PTA tanker feeding device, including a feeding hopper 1. A discharge pipe 2 is connected to the bottom of the feeding hopper 1. An air blowing mechanism 10 for supplying airflow to the inner cavity of the discharge pipe 2 is provided on the side wall of the discharge pipe 2. The air blowing mechanism 10 includes an air pump 12 and multiple diversion pipes 15. The multiple diversion pipes 15 are arranged in a circumferential array on the side wall of the discharge pipe 2, and each diversion pipe 15 has an air outlet 16 extending into the interior of the discharge pipe 2 on both ends of its side wall. The multiple diversion pipes 15 are connected by connecting pipes 14. The air pump 12 is connected to one of the connecting pipes 14 via a conduit 13. The air pump 12 is fixed to the side wall of the discharge pipe 2 by a bracket. Because the bottom of the feeding hopper 1 is straight... As the diameter gradually decreases, the material tends to accumulate and clog at the discharge pipe 2 when falling into the feeding hopper 1. By starting the air pump 12, and with the cooperation of the guide pipe 13, connecting pipe 14 and diverting pipe 15, the air outlet 16 delivers airflow to the inner cavity of the discharge pipe 2, increasing the airflow velocity in the discharge pipe 2. This causes the airflow to blow the material in the discharge pipe 2, loosening the material and facilitating its fall. This effectively prevents the discharge pipe from accumulating and clogging, thus meeting the requirements for stable conveying. The side wall of the discharge pipe 2 is provided with multiple through holes that correspond one-to-one with the air outlet 16, and a sealing structure is provided at the connection between the air outlet 16 and the through hole. The air outlet 16 is flush with the inner wall of the discharge pipe 2.

[0026] A valve cover 8 is provided at the bottom of the feeding pipe 2. A drive mechanism for controlling the opening or closing of the valve cover 8 is provided on the feeding hopper 1. The drive mechanism includes a horizontal plate 3 fixedly connected to the side wall of the feeding hopper 1. A vertical plate 4 is fixedly connected to the end of the horizontal plate 3. A cylinder 5 is rotatably connected to the bottom of the horizontal plate 3 away from the feeding hopper 1 via a rotating shaft. A first connecting rod 7 is rotatably connected to the bottom side wall of the vertical plate 4 via a rotating shaft. A second connecting rod 11 is rotatably connected to the end of the first connecting rod 7 via a rotating shaft. The piston rod end of the cylinder 5 is connected to the rotating shaft at the connection point of the first connecting rod 7 and the second connecting rod 11 via a rotating shaft. 11. A valve cover 8, corresponding to the bottom of the discharge pipe 2, is rotatably connected to the end of the first connecting rod 7 via a rotating shaft. A bracket 6 is provided at the bottom of the horizontal plate 3 near the feeding hopper 1. The bottom of the bracket 6 is rotatably connected to the end of the valve cover 8 via a rotating shaft. Material is added into the feeding hopper 1 from the top. By activating the cylinder 5, the piston rod of the cylinder 5 pulls the valve cover 8 to open, allowing the material to fall from the bottom of the discharge pipe 2 and enter the PTA tanker. By activating the cylinder 5, the piston rod of the cylinder 5 pushes the valve cover 8, thus sealing the bottom of the discharge pipe 2. A silicone foam board 9 is provided on the upper surface of the valve cover 8, which contacts the bottom of the discharge pipe 2. The silicone foam board 9 has low hardness, good resilience, small permanent deformation, and does not stick to powder. When the valve cover 8 is closed, the silicone foam board 9 is tightly attached to the bottom of the discharge pipe 2 under the pressure of the cylinder 5, ensuring reliable sealing and playing a role in shock absorption.
