Description

[Technical Field]

[0001] This utility model relates to the field of nylon production equipment, specifically to a nylon chip material conveying device based on a large silo. [Background Technology]

[0002] In modern industrial production, materials management is one of the core aspects of enterprise operation, affecting production efficiency, cost control, and product quality. Effective materials management ensures the stable operation of the production line, avoids production interruptions caused by material shortages or surpluses, reduces inventory costs, and optimizes the supply chain to ensure timely material supply. Precise materials management plays a decisive role in improving inventory turnover, enhancing cash flow, and rationally allocating resources. In the production process of nylon chips, which demands high precision and efficiency, the importance of materials management is self-evident. Any minor error can disrupt the production process, thereby affecting the quality of the final product and production costs. In the nylon chip production process, the precise management of materials within large silos has always been a challenging problem. From the perspective of nylon production, traditional management methods often fail to achieve real-time and accurate control over key factors such as material levels, consumption patterns, and input-output ratios within the silos.

[0003] From a management perspective, this situation leads to deviations in production cost accounting, which in turn negatively impacts market pricing strategies. At the same time, the efficiency of material input is extremely low, resulting in significant resource waste, and ultimately making it difficult for the economic benefits of the entire production activity to reach the ideal state.

[0004] For example, due to the inability to obtain material level information in real time and accurately, companies may start purchasing materials before the warehouse is full, thereby increasing inventory costs. Furthermore, without a clear understanding of consumption, the amount of materials fed may be inaccurate, which may adversely affect product quality and production progress. [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to provide a nylon chip material conveying device based on a large silo, which can monitor the material level and control the feeding in real time and accurately, avoid production interruption due to material shortage, and ensure production stability; it can prevent chip oxidation, reduce chip dust generation, and improve product quality.

[0006] This utility model is implemented as follows:

[0007] A nylon chip material conveying device based on large silos includes multiple large silos, feeding units, small production silos, and nitrogen tanks. Each large silo is equipped with an inlet pipe and a breather valve at its top. A high-level gauge is installed at the upper end of each large silo, and a low-level gauge is installed at the lower end. A continuous level detector is also installed inside each large silo. The outlet of each large silo is equipped with a first valve, and the outlet of the first valve is connected to a first outlet pipe. The first outlet pipe is connected to at least one set of feeding units.

[0008] The feeding unit includes a weighing tank and a sending tank. The weighing tank is located above the sending tank and is interconnected. The weighing tank has a first inlet valve at its inlet and a first outlet valve at its outlet. The sending tank has a second inlet valve at its inlet and a second outlet valve at its outlet. A nitrogen inlet pipe is also located above the sending tank. A pulse pipe is connected to the pipe at the rear end of the second outlet valve, and a pulse valve is installed on the pulse pipe.

[0009] The discharge end of each feeding unit is connected to the corresponding small production silo; the nitrogen tank is connected to the nitrogen inlet pipe and pulse pipeline of each of the feeding tanks.

[0010] Furthermore, the large hopper is made of stainless steel and has a polished interior.

[0011] Furthermore, the first discharge pipe is also connected to the feeding unit via a rotary valve.

[0012] The advantages of this utility model are:

[0013] This invention achieves real-time monitoring of the nylon chip level inside each large silo by adding continuous level detectors. With high and low level gauges, signals are sent to the control system to issue warnings when there is too much or too little material in the silo, allowing staff to accurately and promptly grasp the actual material situation. The rotary valve and weighing tank enable precise weighing and feeding of materials. The feeding tank prevents chip oxidation and significantly reduces chip dust generation, improving production quality and roll yield.

[0014] In summary, this invention can accurately monitor material level and control feeding in real time, avoiding production interruptions caused by material shortages and ensuring production stability; it can also prevent chip oxidation, reduce chip dust generation, and improve product quality.

[0035] Material feeding tank 22: Used to transport materials to the production hopper (screw hopper) at the end of the production line; the material feeding tank has good sealing performance to prevent material leakage and contamination; it is connected to the nitrogen tank and is filled with nitrogen to protect the slices; a pulse valve is installed at the outlet of the material feeding tank, which is connected to the nitrogen tank, so that the material can be fed in a pulse, which greatly reduces the generation of slice dust and improves production quality and roll full rate.

[0036] In summary, this utility model achieves real-time monitoring of the nylon chip level inside each large silo by adding continuous level detectors. With high and low level gauges, signals are sent to the control system to issue warnings when there is too much or too little material in the silo, allowing staff to promptly and accurately grasp the actual material situation.
