Description

Technical Field

[0001] This utility model belongs to the field of filling device technology, specifically relating to an intelligent temperature-controlled filling system for rubber recycling agents. Background Technology

[0002] As a core material for the resource utilization of waste rubber, the filling stage of rubber reclaiming agent production directly affects output, filling costs, and product quality stability. In the production of rubber reclaiming agents, different batches of raw materials and different production process conditions can lead to variations in the sulfur content. The sulfur content directly affects the vulcanization performance of the reclaiming agent, thus significantly altering its rheological properties and storage stability. Specifically, differences in sulfur content result in significant differences in material viscosity and flowability.

[0003] Traditional filling systems have significant design limitations, often employing a fixed temperature control mode. This mode cannot dynamically adjust the temperature based on the actual composition of the regenerant. When processing high-sulfur materials, the high viscosity of the material under a fixed low-temperature environment leads to pipeline blockage, severely impacting the smooth operation of the production process. Conversely, when dealing with low-sulfur materials, a fixed high-temperature environment may cause the components in the material to decompose, affecting not only product quality but also potentially posing safety hazards.

[0004] Furthermore, while existing filling equipment with filtration functions exists, these devices have shortcomings in filter switching operations. Switching typically requires machine shutdown, which is time-consuming and difficult to clean, undoubtedly disrupting production continuity and reducing efficiency. Simultaneously, filling accuracy is significantly affected by temperature fluctuations, especially when the sulfur content of the rubber reclaiming agent fluctuates. Traditional filling systems struggle to guarantee accurate metering, easily leading to measurement deviations and affecting product quality uniformity. Therefore, developing an intelligent temperature-controlled filling system capable of dynamically adjusting temperature based on the sulfur content of the rubber reclaiming agent, while also possessing efficient filtration, continuous production, and high-precision filling capabilities, is of significant practical importance. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an intelligent temperature-controlled filling system for rubber recycling agents. Through the coordinated operation of three independent temperature control modules, parallel double filter groups and online quality monitoring units, it can achieve constant temperature control of materials throughout the process, non-stop filtration maintenance and real-time quality feedback adjustment. Combined with a weighing feedback filling head and a rotary positioning platform, it can effectively improve filling accuracy and efficiency, ensure product qualification rate and production continuity, and reduce energy consumption and maintenance costs.

[0006] This utility model is achieved using the following technical solution:

[0007] The aforementioned intelligent temperature-controlled filling system for rubber recycling agents includes a reactor, a temporary storage tank, a filling machine, and a control system. The bottom outlet of the reactor is connected to the top inlet of the temporary storage tank via a first conveying pipeline. An electric three-way valve and a parallel double filter assembly are sequentially installed on the first conveying pipeline. The bottom outlet of the reactor is also equipped with a quality monitoring unit. The bottom outlet of the temporary storage tank is connected to the filling machine via a second conveying pipeline. The quality monitoring unit is connected to the control system via a signal line and is linked to the electric three-way valve for control. The other outlet of the electric three-way valve is connected to the return pipeline of the reactor. The reactor, the temporary storage tank, and the filling machine are all equipped with independent temperature control modules. The outlet of the filling machine is equipped with a weighing feedback filling head, and a rotating positioning platform is located below the filling head.

[0008] The parallel dual filter group comprises two basket filters installed in parallel, and each filter is equipped with a control valve and a differential pressure transmitter connected to the control system at its inlet and outlet ends.

[0009] The quality monitoring unit includes an infrared sulfur analyzer and a vibratory viscometer, which are installed in series along the material flow direction.

[0010] The outer walls of the reactor and the temporary storage tank are equipped with steam jackets, and the outer walls of the filling machine hopper are equipped with semiconductor temperature control layers.

[0011] The outer walls of the first delivery pipeline, the second delivery pipeline, and the return pipeline are all provided with a heat insulation layer.

[0012] The filling head includes a weighing sensor, a pneumatic shut-off valve, and a conical nozzle.

[0013] The working principle of the intelligent temperature-controlled filling system for rubber recycling agents is as follows:

[0014] During system operation, the rubber recyclerant that has completed the reaction in the reactor flows out through the bottom outlet. The infrared sulfur analyzer in the quality monitoring unit detects the sulfur content of the material in real time, and the vibrating viscometer measures the viscosity data simultaneously. After the detection data is uploaded to the control system, the temperature control modules of the reactor, temporary storage tank, and filling machine are adjusted according to the preset sulfur content-temperature control curve.

[0015] Qualified materials enter a parallel dual-filter assembly via the first conveying pipeline. When the differential pressure transmitter detects that the differential pressure of the working filter exceeds the limit, the control system automatically switches to the standby filter, achieving continuous filtration without stopping the machine. The filtered material is temporarily stored in a steam-jacketed storage tank for insulation. During the filling stage, a weighing sensor monitors the filling weight in real time, and the feedback controls the opening and closing of the pneumatic shut-off valve. A conical guide nozzle, in conjunction with a rotary positioning platform, achieves precise filling.

[0016] When the quality monitoring unit detects abnormal sulfur content or viscosity, the control system immediately triggers an electric three-way valve to return the material to the reactor via the reflux pipeline for reprocessing, while simultaneously adjusting the reactor temperature to the corrected value. Throughout the process, temperature loss in the control pipeline is managed through the insulation layer to ensure the accurate execution of the sulfur content-temperature control curve.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The intelligent temperature control filling system for rubber regenerator described in this utility model can dynamically adjust the temperature of each link according to the sulfur content of the rubber regenerator, effectively avoiding problems such as excessive viscosity of high sulfur materials at low temperatures clogging the pipeline and decomposition of low sulfur materials at high temperatures caused by differences in sulfur content. It ensures the stability of the physical and chemical properties of the rubber regenerator during the filling process, thereby significantly improving the quality and performance stability of the final product and ensuring the uniformity of product quality.

[0019] (2) The intelligent temperature-controlled filling system for rubber recycler described in this utility model, through the design of a parallel dual-filter group, realizes online switching of filters, and can complete the cleaning or maintenance of filters without stopping the machine, thus ensuring the continuity of production. At the same time, the coordinated operation of each device, with the assistance of an independent temperature control module and insulation measures, reduces production interruptions caused by temperature fluctuations and equipment failures, greatly improves production efficiency, and reduces production costs;

[0020] (3) The intelligent temperature-controlled filling system for rubber recycling agents described in this utility model, through the cooperation of a weighing feedback filling head and a rotary positioning platform, can accurately control the filling weight, avoid overfilling or underfilling, and improve the filling accuracy. In addition, the linkage control between the quality monitoring unit and the electric three-way valve can promptly return unqualified materials, thereby improving the product qualification rate.

[0023] To make the objectives and technical solutions of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1 As shown, the intelligent temperature-controlled filling system for rubber recycling agents includes a reactor 1, a temporary storage tank 2, a filling machine 3, and a control system. The bottom outlet of the reactor 1 is connected to the top inlet of the temporary storage tank 2 via a first conveying pipeline 4. An electric three-way valve 5 and a parallel double filter group are sequentially installed on the first conveying pipeline 4. The bottom outlet of the reactor 1 is also equipped with a quality monitoring unit. The bottom outlet of the temporary storage tank 2 is connected to the filling machine 3 via a second conveying pipeline 7. The quality monitoring unit is connected to the control system via a signal line and is linked with the electric three-way valve 5 for control. The other outlet of the electric three-way valve 5 is connected to the return pipeline 8 of the reactor 1. The reactor 1, the temporary storage tank 2, and the filling machine 3 are all equipped with independent temperature control modules. The outlet of the filling machine 3 is equipped with a weighing feedback filling head 9, and a rotating positioning platform 10 is provided below the filling head 9.

[0026] The parallel dual filter group includes two basket filters 6 installed in parallel, and each filter is equipped with a control valve 11 and a differential pressure transmitter 12 connected to the control system at its inlet and outlet ends.

[0027] The quality monitoring unit includes an infrared sulfur analyzer 13 and a vibratory viscometer 14, which are installed in series along the material flow direction.

[0028] The outer walls of the reactor 1 and the temporary storage tank 2 are provided with steam jackets 15, and the outer walls of the hopper of the filling machine 3 are provided with semiconductor temperature control layers 16.

[0029] The outer walls of the first conveying pipeline 4, the second conveying pipeline 7, and the return pipeline 8 are all provided with a heat insulation layer.

[0030] The filling head 9 includes a weighing sensor 17, a pneumatic shut-off valve 18, and a conical guide nozzle 19.

[0031] The specific steps for doing this are as follows:

[0032] The rubber reclaiming agent that has undergone the chemical reaction in reactor 1 flows out from the bottom outlet and enters the quality monitoring unit. In the quality monitoring unit, the infrared sulfur analyzer 13 and the vibrating viscometer 14 work synchronously. The infrared sulfur analyzer 13 detects the sulfur content of the material in real time, while the vibrating viscometer 14 simultaneously measures the viscosity data of the material. These two key data points are quickly uploaded to the control system. Based on a preset sulfur content-temperature control curve, the control system adjusts the temperature control modules of reactor 1, temporary storage tank 2, and filling machine 3 separately, precisely controlling the temperature of each stage to meet the processing requirements of rubber reclaiming agents with different sulfur contents.

[0033] Materials that pass quality monitoring and are deemed qualified will enter the parallel dual-filter assembly along the first conveying pipeline 4 for filtration. During the filtration process, the differential pressure transmitter 12 continuously monitors the inlet and outlet differential pressure of the working filter. Once the differential pressure transmitter 12 detects that the differential pressure of the working filter exceeds the set limit, the control system will immediately and automatically switch to the standby filter, ensuring that the filtration process can continue without stopping the machine and guaranteeing the continuity of production.

[0034] The filtered rubber recycler enters the temporary storage tank 2 for temporary storage. The outer wall of the temporary storage tank 2 is equipped with a steam jacket 15. By adjusting the temperature of the steam jacket 15, the material inside the tank can be kept warm and maintained within a suitable temperature range to prevent changes in the material properties due to temperature changes.

[0035] Upon entering the filling stage, the weighing sensor 17 at the discharge port of the filling machine 3 begins to monitor the filling weight in real time. When the filling weight reaches the preset value, the weighing sensor 17 sends a signal back to the control system, which then quickly controls the pneumatic shut-off valve 18 to close, stopping the filling process. Simultaneously, the conical guide nozzle 19 and the rotary positioning platform 10 work together. The conical guide nozzle 19 guides the material accurately into the container, while the rotary positioning platform 10 precisely adjusts the container's position to ensure accurate filling and achieve precise filling.

[0036] If, during the quality monitoring process, the quality monitoring unit detects abnormalities in the sulfur content or viscosity of the material, the control system will immediately respond by triggering the electric three-way valve 5 to return the abnormal material to the reactor 1 via the return pipeline 8 for reprocessing. Simultaneously, the control system will adjust the temperature of the reactor 1 to the correction value based on the abnormality to ensure that subsequently processed materials meet quality requirements.

[0037] Throughout the system's operation, the outer walls of the first conveying pipeline 4, the second conveying pipeline 7, and the return pipeline 8 are all equipped with insulation layers. These insulation layers effectively reduce heat loss during material transport, ensuring stable material temperature at each stage. This guarantees the precise execution of the sulfur content-temperature control curve, providing strong support for high-quality filling of the rubber recycler.
