AI Technical Summary
Existing PTA conveying devices are prone to dust and disc damage during unloading, affecting production efficiency and the environment. Furthermore, broken discs may enter the production line, causing equipment blockage and production fluctuations.
A PTA conveying device was designed, including a hopper, a dust filter, horizontal and vertical tubular chain conveying mechanisms, and a guide pipe filter. By setting a filter on the guide pipe to block broken discs, and setting an exhaust port at the top of the hopper to maintain a vacuum, dust is reduced.
It effectively prevents broken discs from entering the production line, keeps the feed smooth, reduces dust, lowers the risk of equipment damage, and improves production stability.

Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of slurry product production equipment, and in particular relates to a PTA conveying device. Background Technology
[0002] The PET unit utilizes PTA tubular chain conveying technology, changing the original two-step method of unloading and pneumatic conveying to the large silo and then pneumatic conveying from the large silo to the daily silo into a one-step direct tubular chain conveying method. The material moves within a closed pipeline, thus preventing leakage and eliminating PTA dust emissions during the process.
[0003] Because the existing hoppers are too small, the exhaust fan pipes are blocked by PTA during unloading, preventing pressure reduction and vacuuming. This causes PTA to leak from the unloading port, resulting in PTA dust flying everywhere, causing raw material loss and environmental pollution. Furthermore, as the tubular chain conveyor system operates for longer periods, the feeding discs may break or break. The main reasons for this damage are: 1) aging of the disc material itself; 2) blockage in the closed pipe, increasing stress on the discs; and 3) high moisture content in the PTA material, increasing the conveying force. Damaged discs first reduce conveying capacity. More dangerously, broken discs may enter the daily feed hopper of the PET production line via the tubular chain conveyor system, then into the small hopper of the PTA scale, potentially jamming the rollers inside the hopper or even deforming them. In severe cases, this can affect the feeding speed and cause production fluctuations. Utility Model Content

[0023] To better understand the purpose, structure, and function of this utility model, a PTA conveying device of this utility model will be described in further detail below with reference to the accompanying drawings.
[0024] like Figure 1-2As shown, this utility model discloses a PTA conveying device, including a hopper 1, an operating platform 2 on one side of the hopper 1, a dust filter 5 connected to the hopper 1, an exhaust port 3 in the middle of the upper surface of the hopper 1, and the dust filter 5 connected to the exhaust port 3 via a conduit. Feed inlets 4 are located on both sides of the exhaust port 3 on the upper surface of the hopper 1. By placing the exhaust port 5 at the top of the hopper 1, it will not be blocked by PTA dust, allowing for continuous vacuuming to create a good low pressure, ensuring smooth feeding and reducing dust dispersion. Furthermore, by placing the operating platform 2 on one side of the hopper 1, operators can perform bag cutting operations from the side. Even if a PTA bag falls from above the hopper 1, it will not injure the operator, greatly reducing operational risks.
[0025] A first horizontal tubular chain conveyor 6 is installed at the bottom of the hopper 1. A vertical tubular chain conveyor 7 is connected to the end of the first horizontal tubular chain conveyor 6. A second horizontal tubular chain conveyor 8 is installed on one side of the top of the vertical tubular chain conveyor 7. The tubular chain conveyor is a mature existing technology and will not be described in detail here. The bottom of the second horizontal tubular chain conveyor 8 away from the vertical tubular chain conveyor 7 is connected to the daily feed bin 11 through a guide pipe 9. A filter 10 is installed on the guide pipe 9. The filter 10 includes a shell 12. An inlet 13 is installed at the top of the shell 12 and an outlet 14 is installed at the bottom. A filter screen 16 is installed on the inner wall of the shell 12. A hand hole 15 is installed on the side wall of the shell 12. The inlet 13 and outlet 14 are diagonally arranged, and the outer shell 12 has a bulging structure. The filter screen 16 is set at an angle, and the hand hole 15 is located above the filter screen 16. The hand hole 15 is equipped with a fixed cover. Since the discs of the tubular chain conveyor mechanism will enter the daily feed bin 11 and then enter the PTA scale after they break, affecting the production feed, the filter 10 is set on the guide pipe 9 so that the broken discs are blocked on the filter screen 16. The broken discs can be removed through the hand hole 15. By making the outer shell 12 into a bulging structure, the chance of the filter 10 being blocked can be reduced, and the broken discs can be removed easily. According to the actual application, the aperture of the filter screen 16 should be 6 cm to block the discs without affecting the feeding.
