Description

Technical Field

[0001] This utility model relates to a rubber production system, specifically to a rubber granule surface anti-adhesion treatment system, belonging to the technical field of rubber production equipment. Background Technology

[0002] The production processes of polymers such as halogenated butyl rubber and food-grade butyl rubber typically include high-temperature, high-pressure extrusion dehydration and expansion drying. While these processes remove most volatile substances, the inherent viscosity of the rubber polymer becomes particularly pronounced at high temperatures. When the rubber is rotary-cut into granules, these hot and sticky granules easily agglomerate and even clump together during transport and subsequent drying. This agglomeration leads to a series of problems. First, granule agglomeration directly affects drying efficiency, making it difficult to remove internal moisture, thus hindering production line capacity and causing energy waste. Second, uneven heating between agglomerated and dispersed granules can cause color differences, affecting product appearance and increasing defect rates. Finally, agglomeration also affects the physicochemical stability of the product, consequently impacting downstream processing and use.

[0003] Therefore, there is an urgent need in this field for a rubber particle surface anti-adhesion treatment system that has a relatively simple structure, low equipment cost and maintenance difficulty, and good operational stability. Utility Model Content

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0025] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0027] like Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention discloses a rubber particle surface anti-adhesion treatment system. The system includes a rubber processing device 100 for processing and conveying rubber particles, and a reagent atomizing supply device 200 for supplying anti-adhesion reagent to the rubber particles.

[0028] The reagent atomizing supply device 200 adopts a pumpless design, utilizing the Venturi effect generated when high-speed compressed air flows through the mixing connector 202 to create a negative pressure at the port of the reagent suction line 205, thereby drawing in and atomizing the reagent in the reagent container 201. This structure is simple, eliminates the need for a liquid pump, and significantly reduces manufacturing costs.

[0029] In one specific embodiment, the rubber processing equipment 100 includes an extrusion dewatering machine 101, an expansion dryer 102, a feeding conveyor 103, a fluidized bed 104, a material distribution feeder 105, and a briquetting machine 106 connected in sequence, covering all key processes from rubber dewatering to final briquetting.

[0030] To achieve optimal processing results, the system employs multiple reagent atomizing supply devices 200, with corresponding nozzles 203 strategically positioned at key locations where rubber particles are prone to agglomeration: the outlet of the extrusion dewatering machine 101, the inlet and outlet of the expansion dryer 102, the inlet of the feeding conveyor 103, the inlet and outlet of the fluidized bed 104, the inlet of the distributing feeder 105, and the inlet of the briquetting machine 106. This multi-point layout allows for segmented, targeted anti-agglomeration treatment, addressing the changing viscosity of rubber particles at different processing stages, ensuring that the rubber particles maintain good dispersion throughout the entire conveying and drying process.

[0031] Each reagent atomizing supply device 200 includes a reagent tank 201, a mixing connector 202, and a nozzle 203 connected by multiple pipelines. The reagent tank 201 is used to hold liquid anti-blocking reagents, and the mixing connector 202 is a standard tee connector. The nozzle 203 is a conical atomizing nozzle 203. The multiple pipelines are as follows: one end of the air supply pipeline 204 is connected to a compressed air source in the workshop, and the other end is connected to the first port 2021 of the mixing connector 202. A pneumatic valve 2041 is installed on this pipeline. One end of the reagent suction pipeline 205 is connected to the second port 2022 of the mixing connector 202, and the other end extends vertically into the reagent tank 201 from the top opening, ensuring that its end opening is always submerged below the liquid surface. One end of the spray output pipeline 206 is connected to the third port 2023 of the mixing connector 202, and the other end is connected to the nozzle 203.

[0032] To achieve automated operation, the system also includes a control unit 300. The control unit 300 is specifically a PLC controller. The control unit 300 is electrically connected to the solenoid coils of all pneumatic valves 2041 via cables. The consumption of the anti-adhesion reagent is controlled by setting the spray interval and duration parameters. In this embodiment, the spray interval is set to 5-10 seconds, and the spray duration is set to 2-5 seconds.

[0033] The workflow of this utility model is described below.

[0034] During the preparation stage, the prepared liquid anti-adhesion reagent is added to the reagent tank 201, and the spraying program is preset on the control unit 300 according to the production conditions, setting the spraying interval time and the single spraying time.

[0035] After the rubber production line starts up and enters a stable operating state, the control unit 300 executes a preset program, periodically sending an opening electrical signal to the pneumatic valve 2041. The pneumatic valve 2041 is opened, and compressed air from the air source rushes into the mixing joint 202 at high speed through the air supply line 204. The high-speed airflow creates a significant negative pressure zone inside the mixing joint 202, directly opposite the connection port of the reagent suction line 205.

[0036] Because the liquid surface inside reagent container 201 is subjected to atmospheric pressure, this atmospheric pressure creates a pressure difference with the negative pressure inside mixing connector 202, thereby forcing the reagent into mixing connector 202 through reagent suction line 205. The suctioned liquid reagent is violently mixed with high-speed airflow inside mixing connector 202, instantly atomized into extremely fine droplets, and then sprayed evenly from nozzle 203 onto the surface of the moving rubber particles through spray output line 206, forming a separating film that effectively prevents the particles from sticking together.

[0037] After a single spray reaches the preset duration, the control unit 300 sends a shutdown signal, the pneumatic valve 2041 closes, and the spraying stops. After waiting for a preset interval, the system repeats the spraying process, and so on, to achieve continuous and efficient anti-adhesion treatment of rubber particles.

[0038] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
