Description

Technical Field

[0001] This utility model relates to the field of polyester chip technology, and in particular to a polyester chip conveying system with an additional conveying platform device. Background Technology

[0002] Currently, in common polyester chip conveying systems, multiple intermediate silos are usually set up on the conveying pipeline to temporarily store polyester chip materials. Each intermediate silo is equipped with a separate feeding mechanism. The polyester chip materials are quantitatively and stably conveyed to the finished product silo by rotating the feeding rotary valve in the feeding mechanism.

[0003] However, the aforementioned "one bin, one valve" structure has a significant drawback: if the rotary valve in one of the intermediate bins malfunctions, such as jamming of the discharge control valve rotor, damage to the drive motor, or seal failure, the discharge operation of that intermediate bin must be stopped and the machine shut down for maintenance to prevent the fault from escalating or to allow the finished product to be discharged locally. This will lead to a decrease in the conveying capacity of the entire slicing conveying system, and in severe cases, it will affect production continuity, increase production losses, and increase costs.

[0004] Based on this, a polyester chip conveying system will be designed with an additional conveying stand device, which can quickly replace the faulty original feeding rotary valve and ensure continuous production. Utility Model Content

[0005] The present invention aims to overcome the defects in the prior art by providing a device for adding a conveying stand to a polyester chip conveying system.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a polyester chip conveying system with an additional conveying stand device, including a conveying pipeline, an air source control valve, an intermediate silo mechanism, and a finished product silo. The air source control valve is located at the front end of the conveying pipeline, and the intermediate silo mechanism is located in the middle of the conveying pipeline. The intermediate silo mechanism includes an intermediate silo and a feeding mechanism for controlling the discharge of polyester chip material from the intermediate silo. A spare feeding mechanism connected to the conveying pipeline is also provided between the two intermediate silo mechanisms. The finished product silo is located at the rear end of the conveying pipeline. Conveying air enters the conveying pipeline through the air source control valve and conveys the polyester chips discharged from the intermediate silo mechanism to the finished product silo.

[0007] As a preferred embodiment of this utility model, the feeding mechanism includes a feeding valve, a feeding rotary valve, and a discharge valve, which are connected in sequence. The feeding valve is connected to an intermediate silo, and the discharge valve is connected to a conveying pipeline.

[0008] As a preferred embodiment of this utility model, the backup feeding mechanism includes a backup feeding valve, a backup feeding rotary valve, and a backup discharge valve, with two backup feeding valves installed on the backup feeding rotary valve.

[0009] In a preferred embodiment of this utility model, one end of the spare discharge valve is connected to the intermediate silo, and the other end of the spare discharge valve is connected to the spare discharge rotary valve. The spare discharge rotary valve is connected to the conveying pipeline through the spare discharge valve.

[0010] In a preferred embodiment of this utility model, the number of spare discharge valves is greater than 2, one end of the spare discharge valve is connected to the intermediate silo, and the other end of the spare discharge valve is connected to the spare discharge rotary valve.

[0011] In a preferred embodiment of this utility model, the standby rotary valve for discharging material is connected to the standby discharge valve via a flange, and the standby rotary valve for discharging material is connected to the standby discharge valve via a flange.

[0012] As a preferred embodiment of this utility model, the number of finished product silos is at least two.

[0013] As a preferred embodiment of this utility model, the conveying pipeline includes a main conveying pipeline and branch conveying pipelines, and the finished product silo is connected to the main conveying pipeline through the branch conveying pipelines.

[0014] As a preferred embodiment of this utility model, a pipeline pressure sensor and a speed monitoring sensor are also sequentially installed on the delivery pipeline.

[0015] In a preferred embodiment of this invention, the pipeline pressure sensor and the speed monitoring sensor are located at the output end of the delivery pipeline.

[0016] The beneficial effects of this utility model are: 1. This utility model, by adding a spare feeding rotary valve and matching backup feeding valve and backup discharge valve, realizes the sharing of a set of backup feeding mechanisms between two intermediate silos. When any of the original feeding rotary valves fails, there is no need to stop the machine. The feeding function of the corresponding intermediate silo can be quickly restored by simply switching valves and starting the backup feeding rotary valve. This effectively avoids production interruptions caused by equipment failure and significantly improves production continuity.

[0017] 2. The pressure sensor and speed monitoring sensor added to this utility model further enhance the device's ability to warn and respond to faults, and improve the overall operational reliability of the polyester chip conveying system.

[0018] 3. This utility model only requires the addition of a spare feeding mechanism to replace the two intermediate silos, which greatly reduces the equipment procurement cost and installation space occupation. At the same time, the unified equipment structure also reduces the subsequent spare parts management and maintenance costs, resulting in high cost-effectiveness.

[0019] 4. This utility model does not require large-scale modifications to the original conveying pipelines, intermediate silos, and original feeding mechanisms. It can avoid the failure of the feeding mechanism simply by connecting the backup feeding mechanism. It is easy to install and has strong compatibility. At the same time, if the number of intermediate silos needs to be increased in the future, it is only necessary to expand and add the corresponding branch pipelines to achieve the coverage of more intermediate silos by the backup feeding rotary valve, which has good scalability.

Detailed Implementation

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1:

[0022] like Figure 1 As shown, a polyester chip conveying system with an additional conveying stand includes a conveying pipeline 1, an air source control valve 2, an intermediate silo mechanism 3, and a finished product silo 4. The air source control valve 2 is located at the front end of the conveying pipeline 1, and is preferably a pneumatic switch plunger valve. The intermediate silo mechanism 3 is located in the middle of the conveying pipeline 1. The intermediate silo mechanism 3 includes an intermediate silo 31 and a feeding mechanism 32 that controls the discharge of polyester chip material from the intermediate silo 31. A spare feeding mechanism 5 connected to the conveying pipeline 1 is also provided between the two intermediate silo mechanisms 3. The finished product silo 4 is located at the rear end of the conveying pipeline 1. The conveying air enters the conveying pipeline 1 through the air source control valve 2 and conveys the polyester chip material discharged from the intermediate silo mechanism 3 to the finished product silo 4.

[0023] Specifically, the intermediate silo 31 is used to temporarily store polyester chips. Each intermediate silo 31 is equipped with a separate feeding mechanism 32 at its discharge port. The feeding mechanism 32 is used to quantitatively and stably transport the polyester chips to the finished product silo 4. When any feeding mechanism 32 fails, the intermediate silo 31 can quickly switch to the backup feeding mechanism 5. The backup feeding mechanism 5 takes over to quantitatively and stably transport the polyester chips, ensuring continuous and stable production.

[0024] Furthermore, when the feeding mechanism 32 corresponding to the intermediate silo 31 is not faulty, the standby feeding mechanism 5 can also be activated. Its cooperation with the feeding mechanism 32 can increase the conveying capacity of polyester chips and make the conveying range of polyester chips wider. The feeding mechanism 32 and the standby feeding mechanism 5 do not interfere with each other during the conveying of polyester chips.

[0025] This utility model provides a backup feeding mechanism 5 connected to the conveying pipeline 1 between the two intermediate silo mechanisms 3, so that when any of the original feeding mechanisms 32 fails, the backup feeding mechanism 5 can be quickly switched to, avoiding downtime and ensuring continuous and stable production.

[0026] The structure of the feeding mechanism 32 and the standby feeding mechanism 5 and their coordinated use are explained in detail.

[0027] The feeding mechanism 32 includes a feeding valve 321, a feeding rotary valve 322, and a discharge valve 323. The feeding valve 321, the feeding rotary valve 322, and the discharge valve 323 are connected in sequence. The feeding valve 321 is connected to the intermediate silo 31, and the discharge valve 323 is connected to the conveying pipeline 1.

[0028] The backup feeding mechanism 5 includes a backup feeding valve 51, a backup feeding rotary valve 52, and a backup discharge valve 53. Two backup feeding valves 51 are installed on the backup feeding rotary valve 52.

[0029] One end of the standby discharge valve 51 is connected to the intermediate silo 31, and the other end of the standby discharge valve 51 is connected to the standby discharge rotary valve 52. The standby discharge rotary valve 52 is connected to the conveying pipeline 1 through the standby discharge valve 53.

[0030] The standby rotary valve 52 and the standby discharge valve 51 are connected by a flange, and the standby rotary valve 52 and the standby discharge valve 53 are connected by a flange. Wear-resistant sealing gaskets are installed between the flanges. The flange connection facilitates disassembly and maintenance, while the wear-resistant sealing gaskets can extend the service life of the sealing components and ensure the long-term sealing reliability of the device.

[0031] Among them, the discharge valve 321 and the spare discharge valve 51 are preferably pneumatic gate valves or electric shut-off valves. Electric gate valves or electric shut-off valves can be remotely controlled by an external control system, and the switching speed is faster. They are suitable for high automation and meet the requirements of continuous discharge. The rotary valve 322 and the spare discharge rotary valve 52 are preferably pneumatic butterfly valves of model CFH320-25-SS / SS / AC-P. The above-mentioned unified model facilitates spare parts procurement and inventory management, and can also reduce the operation difficulty of maintenance personnel and improve maintenance efficiency.

[0032] Specifically, there are at least two intermediate silo mechanisms 3 on the conveying pipeline 1, which are arranged sequentially along the conveying direction of the conveying pipeline 1. The discharge end of each intermediate silo mechanism 3 is connected to the conveying pipeline 1. The discharge rotary valve 322 is used to control the amount of material discharged from the intermediate silo 31 to the conveying pipeline 1. The discharge valve 321 controls the connection or disconnection between the intermediate silo 31 and the discharge rotary valve 322. The discharge valve 323 controls the connection or disconnection between the discharge rotary valve 322 and the conveying pipeline 1. When the backup feeding mechanism 5 is added, the backup feeding rotary valve 52 is connected to different intermediate silos 31 through two backup feeding valves 51. The backup feeding rotary valve 52 is connected to one of the intermediate silos 31 and can control the amount of material fed from the intermediate silo 31 to the conveying pipeline 1. The backup feeding valve 51 controls the connection or disconnection between the feeding rotary valve 52 and the intermediate silo 31. The backup discharge valve 53 controls the connection or disconnection between the backup feeding rotary valve 52 and the conveying pipeline 1, so as to realize the replacement function of the backup feeding rotary valve 52 for the feeding rotary valve 322.

[0033] This utility model, by adding a spare feeding rotary valve 52 and matching backup feeding valve 51 and backup discharge valve 53, enables two intermediate material bins 31 to share a set of backup feeding mechanisms 5. When any of the original feeding rotary valves 322 fails, there is no need to stop the machine. The feeding function of the corresponding intermediate material bin 31 can be quickly restored by simply switching valves and starting the backup feeding rotary valve 52. This effectively avoids production interruptions caused by equipment failure and significantly improves production continuity.

[0034] The number of finished product silos 4 is at least 2. The conveying pipeline 1 includes a main conveying pipeline 11 and a branch conveying pipeline 12. The finished product silos 4 are connected to the main conveying pipeline 11 through the branch conveying pipeline 12, which facilitates the quantitative and zoned storage of polyester chip materials.

[0035] Pressure sensor 6 and speed monitoring sensor 7 are also sequentially installed on the conveying pipeline 1. The pressure sensor 6 and speed monitoring sensor 7 are connected to the central control DCS control system of the device. The pressure sensor 6 and speed monitoring sensor 7 are located at the output end of the conveying pipeline 1. When the discharge rotary valve 322 malfunctions, causing the conveying pipeline 1 to become blocked and the pressure to rise abnormally, the pressure sensor 6 or speed monitoring sensor 7 can send a signal to the control system in a timely manner to remind the operator to check the equipment status. If the discharge rotary valve 322 is confirmed to be faulty, the switching process of the backup discharge rotary valve 52 can be quickly started to further improve the fault response speed of the device.

[0036] The addition of pressure sensor 6 and speed monitoring sensor 7 to this invention further enhances the device's ability to warn and respond to faults, thereby improving the overall operational reliability of the polyester chip conveying system.

[0037] This utility model only requires the addition of a spare feeding mechanism 5 to replace the two intermediate material bins 31, which greatly reduces the equipment procurement cost and installation space occupation. At the same time, the unified equipment structure also reduces the subsequent spare parts management and maintenance costs, resulting in high cost-effectiveness. Example 2:

[0038] The number of spare discharge valves 51 is greater than 2. One end of each spare discharge valve 51 is connected to the intermediate silo 31, and the other end of each spare discharge valve 51 is connected to a spare discharge rotary valve 52.

[0039] Compared to Embodiment 1, Embodiment 2 has more backup feeding valves 51, meaning that the backup feeding mechanism 5 can connect to more than 2 intermediate material bins 31, enabling switching of the feeding mechanism 32 corresponding to more intermediate material bins 31 after failure, thus saving the cost of the device.

[0040] This invention does not require large-scale modifications to the original conveying pipeline 1, intermediate silo 31, and original feeding mechanism 32. It can avoid the failure of feeding mechanism 32 simply by connecting the backup feeding mechanism 5. It is easy to install and has strong compatibility. At the same time, if the number of intermediate silos 31 needs to be increased in the future, it is only necessary to expand and add the corresponding branch pipelines to achieve the coverage of more intermediate silos 31 by the backup feeding rotary valve 5, which has good scalability.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0042] Although this document uses numerous reference numerals from the accompanying drawings, such as 1 for conveying pipeline, 2 for air source control valve, 3 for intermediate silo mechanism, 4 for finished product silo, 5 for standby discharge mechanism, 6 for pressure sensor, 7 for speed monitoring sensor, 11 for main conveying pipeline, 12 for branch conveying pipeline, 31 for intermediate silo, 32 for discharge mechanism, 51 for standby discharge valve, 52 for standby discharge rotary valve, 53 for standby discharge valve, 321 for discharge valve, 322 for discharge rotary valve, and 323 for discharge valve, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
