Technical Field
[0001] This utility model relates to the field of material handling equipment technology, and in particular to a liquid flow temperature-controlled molten material feeder suitable for use in molten material granulation systems. Background Technology
[0002] In the petrochemical refining and petrochemical industries, a large amount of high-temperature liquid molten material byproducts are generated, such as molten liquid sulfur at around 135°C, molten liquid petroleum resin and phenolic resin at around 210°C, molten liquid paraffin at around 58°C, and rubber additives at around 52°C. These liquid byproducts must be cooled and solidified before they can be utilized. Currently, the cooling and solidification of these high-temperature liquid molten materials is accomplished by granulation systems, primarily using steel belt material cooling conveyors. Their basic structure is as follows: Figure 1 As shown: The main body includes a frame 1, a main drive drum 2 and a driven tension drum 3 respectively set at the front and rear ends of the frame 1, a steel strip carrying platform 4 set between the left and right side frames of the frame, a steel strip 5 set in a closed loop between the main drive drum 2 and the driven tension drum 3, a water cooling mechanism 6 set below the steel strip carrying platform 4 and equipped with a water spray nozzle 61, a cooling water inlet 62 and a cooling water outlet 63, a molten material feeder 7 set above the driven tension drum 3, and a feeding scraper 8 and a feeding hopper 9 set beside the main drive drum 2. During operation, the steel belt is supported by a steel belt carrying platform and is closed-loop tensioned on the main drive drum and the driven tension drum. Driven by the main drive drum and cooled by the water-cooling mechanism, the high-temperature liquid molten material, continuously fed from the molten material feeder 7 onto the surface of the steel belt, continuously evaporates, cools, and solidifies into a lower-temperature solid product that meets usage requirements as it is transported from one end of the conveyor to the other. Finally, it is scraped off by the discharge scraper and enters the hopper into the storage bin. Its drawback is that because the high-temperature liquid molten material is continuously fed onto the steel belt in an uncontrolled manner, its flow rate, falling range, and accumulation thickness are difficult to control. Therefore, the final cooled and solidified sheet-like product has uneven thickness, making it difficult to meet customer requirements. To address this, a novel trough-type material distributor has been developed, fixed between the left and right frames of the frame below the molten material feeder 7. This allows the liquid molten material to first collect in the feed trough and then be orderly discharged through the discharge holes, ensuring even distribution. Its basic structure is as follows: Figures 2-4As shown: The main body is elongated, including an upper feed trough 11 made of hollow square steel, a lower trough seat 12 made of H-shaped steel, and a silicone interconnecting strip 13 bonded at the junction of the upper feed trough 11 and the lower trough seat 12. The upper feed trough 11 has several large-diameter feed holes 111 fixed on its top surface and several small-diameter discharge holes 112 evenly spaced on its bottom surface, with the central cavity serving as a feed trough 113. The lower trough seat 12 is elongated and conforms to the upper feed trough 11. An axial groove 121 is centrally fixed on the top surface of the intermediate strip. Limiting shoulders 122 are fixed on the left and right sides of the axial groove 121, and upwardly convex limiting shoulders, whose inner wall width matches the outer width of the upper feed trough 11, are formed by the left and right side edges. The edge 123 has several small-diameter feeding holes 124 evenly distributed and fixed on the bottom of the axial groove 121 of the middle partition. On the back of the middle partition, there are seat legs 125, which are served by the left and right side edges, and a feeding groove 126, which is served by the cavity between the legs. In the assembled state, the upper feeding square groove 11 is supported at the bottom by the left and right limiting shoulders 122, limited to the left and right by the upper convex limiting edge 123, and bonded at the junction by silicone interconnecting strips 13, thus being integrated with the lower groove seat 12. During operation, the high-temperature liquid molten material from the molten material feeder 7 first enters the material groove 113 through the large-diameter feeding hole 111 on the top surface, then flows down through the small-diameter discharge hole 112 on its bottom surface, enters the axial groove 121, and after being gently compressed, drips out through the small-diameter feeding hole 124, achieving uniform material distribution. This is theoretically feasible. However, in practice, it has been found that due to the different temperature characteristics of various types of high-temperature molten liquid materials, when these relatively high-temperature molten liquid materials enter the room-temperature metal trough-type feed distributor, they thicken to varying degrees due to temperature differences, easily adhering to the hole walls or cavity walls. This leads to poor flow, easily causing blockages and leaks, and even causing components to separate, affecting normal material distribution. This necessitates frequent downtime for maintenance or replacement, not only polluting the environment and wasting resources, but also directly impacting the normal operation, production efficiency, and daily operating costs of the automated granulation system. Therefore, from both a practical and economic perspective, it is unsatisfactory and cannot fully meet the requirements of continuous, efficient, high-quality, environmentally friendly, and low-cost production in automated assembly line systems. This has become a major problem plaguing the industry and urgently needs to be solved. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing material distributors used in molten material granulation systems, and to provide a liquid flow temperature-controlled molten material distributor with a relatively scientific and simple structure, safe and reliable operation, and environmental protection. This distributor can prevent material leakage and product component separation, ensure normal working life, and meet the requirements of continuous and uniform material distribution.
[0004] This utility model relates to a liquid flow temperature-controlled molten material feeder distributor, characterized in that the main body includes a feeder, a liquid supply temperature control system, and interconnecting components, wherein:
[0005] The main body of the feeder is elongated and has the function of controlled temperature change and ensuring smooth discharge of molten material. It includes an upper feed trough and a lower discharge base. The main body of the upper feed trough is elongated with a centrally located concave axial feed trough and several discharge holes fixed at intervals on the bottom of the trough. The main body of the lower discharge base is elongated with a centrally located concave mounting groove that matches the upper feed trough on its main surface and convex limiting strips fixed on the left and right side surfaces. On the bottom of the mounting groove, a middle transition trough, evenly distributed discharge holes fixed on its bottom, and a discharge trough served by the concave cavity at the lower end of the discharge holes are fixed in sequence from top to bottom. On the left and right sides of the middle transition trough, a liquid supply channel and a liquid return channel with interconnected top liquid passages are also fixed in parallel.
[0006] The liquid supply temperature control system includes a temperature sensor, a liquid output pipe and a liquid return pipe respectively equipped with sealed installation connection ends, and a PLC control cabinet with functions of on-demand temperature setting, on-demand liquid heating and real-time adjustment of liquid supply temperature, and automatic control of circulating liquid supply.
[0007] The interconnecting component body is axially aligned with the main body of the fabric distributor, and is provided with a limiting mounting hole for a temperature sensor, a sealing mounting connector A for a liquid output pipe, and a sealing mounting connector B for a liquid return channel.
[0008] In the assembled state, the distributor is fixed between the left and right frames of the frame below the molten material feeder; the temperature sensor is embedded in the lower discharge base of the distributor through the limiting installation hole to perform real-time detection and feedback of the real-time working environment temperature information of the liquid flow; the liquid flow output pipe and the liquid flow return channel are connected in a leak-free manner through their respective sealed installation connection ends and sealed installation connection seats, and are connected to the corresponding liquid flow channels of the liquid supply channel and the liquid return channel on the lower discharge base;
[0009] During operation, the PLC control cabinet sets the rated temperature of the heated liquid as needed based on the temperature characteristics of the molten material being processed, starts the circulating liquid supply, heats the main body of the distributor, and controls the liquid supply temperature as needed based on the real-time temperature information returned by the temperature sensor, so as to establish a working environment temperature on the main body of the distributor that meets the requirements for keeping the molten material being processed in a liquid state, thereby ensuring that the molten material being processed flows normally and unobstructed and is evenly distributed in the distributor;
[0010] Furthermore, the liquid heating medium is water or oil, which has good heat storage and co-current functions.
[0011] Based on the above concept, this utility model of a liquid flow temperature-controlled molten material distributor adds a liquid flow circulation heating channel using water or oil as the heat transfer medium. This facilitates full contact with the distributor body, gentle heat conduction, and uniform temperature distribution. Furthermore, it is equipped with a system that allows setting the rated heating temperature of the heat transfer liquid medium according to the temperature characteristics of the molten material being processed. Based on real-time temperature detection and feedback from a temperature sensor of the distributor body, it heats and controls the liquid supply temperature as needed, achieving closed-loop control of the distributor body temperature. This ensures the temperature of the molten material being processed is consistently high. This system ensures unimpeded, sequential, and uniform material distribution within a consistently normal liquid temperature environment. It effectively solves a long-standing problem in existing technologies where the significant temperature difference between the molten material and the main body of the distributor causes the material to thicken, adhere to the cavity or orifice walls, resulting in poor flow, blockages, leaks, or component separation. This ultimately affects the continuous, safe, efficient, and environmentally friendly low-cost production of automated granulation systems. The system boasts a simple and scientifically sound structure, safe and reliable operation, and environmental friendliness, fully meeting the requirements for continuous, efficient, high-quality, environmentally friendly, and low-cost production in molten material granulation systems. It represents a major innovation in this technical field, possessing strong practicality and promising market application prospects. Attached Figure Description
