Description

Technical Field

[0001] This utility model relates to the field of rubber accelerators, and more specifically, to a drying device for purifying rubber accelerators. Background Technology

[0002] Rubber accelerators are a class of fine chemical products that can accelerate the vulcanization reaction between rubber and vulcanizing agents, shorten vulcanization time, lower vulcanization temperature, reduce the amount of vulcanizing agent used, and improve the physical and mechanical properties of vulcanized rubber. Simply put, they are like catalysts in the rubber vulcanization process, enabling rubber products to be molded faster and better. From the perspective of the mechanism of action, rubber accelerators can undergo complex chemical reactions with rubber molecules, vulcanizing agents, etc. during the vulcanization process to generate active intermediate products, thereby improving the speed and efficiency of the vulcanization reaction. In actual production, adding rubber accelerators can not only significantly improve production efficiency, but also reduce energy consumption costs. For example, traditional rubber vulcanization may require a long time and a high temperature, while adding accelerators can significantly shorten the vulcanization time, speed up the production cycle, and reduce energy consumption.

[0003] In the production and purification process of rubber accelerators, the raw materials of the rubber accelerators need to be dried. A search revealed an existing patent (publication number: CN219674681U) that discloses a high-efficiency rubber accelerator drying device, including a machine body. A drying cylinder is installed inside the machine body. A second motor is installed on the outer wall of the machine body. The output end of the second motor passes through the outer wall of the machine body and the outer wall of the drying cylinder and is equipped with a stirring rod. Rubber accelerator granules are added into the feed cylinder. Then, the first motor is started, causing the screw to rotate and transport the rubber accelerator into the drying cylinder. Then, two hot air blowers are started, and the hot airflow generated is introduced into the drying cylinder through two ventilation pipes, two connecting pipes, and multiple drying pipes to dry the rubber accelerator granules. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology:

[0004] Existing drying equipment for purifying rubber accelerators requires injecting a portion of the rubber accelerator into the drying drum for agitation and drying before discharging the dried rubber accelerator. This drying method makes it difficult to continuously dry the rubber accelerator, thus reducing the drying speed.

[0005] Therefore, a drying device for purifying rubber accelerators is proposed to address the above problems. Utility Model Content

[0010] Preferably, the upper surface of the support cover is fixedly connected to two support seats, and the upper surfaces of the two support seats are fixedly connected to the bottom surface of the conveying cylinder.

[0011] Preferably, the upper surface of the conveying cylinder is fixedly connected to a feeding hopper, which is located above the right end of the spiral blade.

[0012] Preferably, the upper surface of the electric heating guide plate is provided with a guide groove, and the electric heating guide plate has a certain tilt angle.

[0013] Preferably, the bottom surface of the conveyor box is fixedly connected to two sets of support bases, and the bottom surface of both sets of support bases is provided with shock-absorbing pads.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] Compared with existing technologies, this drying equipment for purifying rubber accelerators allows the rubber accelerator to enter the conveyor cylinder through the feeding hopper. The accelerator is continuously conveyed by a screw feeder and preheated simultaneously by an arc-shaped electric heating plate. The flow of the rubber accelerator is guided by an electric heating guide plate and subjected to secondary drying. Subsequently, hot air from a hot air blower assists in the drying process. In addition, the rubber accelerator is sent to the area below an infrared radiator for deep drying by an electric drive roller. Finally, it is discharged from the left end of the conveyor belt. The entire process can be carried out continuously without interruption due to frequent feeding and unloading, thus improving drying efficiency and throughput per unit time.

[0016] Compared with existing technologies, this drying equipment for purifying rubber accelerators can achieve stepped heating through the setting of arc-shaped electric heating plates and electric heating guide plates. In addition, the hot air blower provides circulating hot air, and the infrared radiator performs penetrating deep drying of the rubber accelerator. Thus, it can perform multiple drying processes on the rubber accelerator from preheating, secondary heating to deep drying, ensuring that the rubber accelerator is dried evenly and thoroughly, improving drying quality and equipment reliability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] As attached Figures 1-5 The drying equipment shown includes a conveyor box 1, a support cover 2 fixedly connected to the upper surface of the conveyor box 1, a connecting pipe 3 fixedly connected to the upper surface of the support cover 2, a conveying cylinder 4 fixedly connected to the top end of the connecting pipe 3, a spiral feeding component 5 provided on one side of the conveying cylinder 4, an arc-shaped electric heating plate 7 fixedly installed on the inner top wall of the conveying cylinder 4, an electric heating guide plate 8 fixedly installed on the inner wall of the support cover 2, and multiple infrared radiators 12 fixedly installed on the inner wall of the support cover 2. The infrared radiators 12 mainly contain infrared heating elements, commonly including infrared heating tubes and infrared heating plates. These elements can emit infrared radiation waves after being energized. Infrared radiation has strong penetrating power and can directly act on the rubber accelerator, allowing the rubber accelerator's interior and surface to absorb heat simultaneously, achieving rapid and efficient deep drying. The radiator 12 is equipped with a reflector structure to concentrate and reflect infrared radiation onto the rubber accelerator area above the conveyor belt 10, thereby improving heat utilization. An electric drive roller 11 is installed on the inner wall of the conveyor box 1. The electric drive roller 11 has a built-in motor drive device that converts electrical energy into mechanical energy to drive its own rotation. In turn, it drives the conveyor belt 10 to rotate by friction, providing power for the movement of the rubber accelerator in the conveyor box 1. The roller is usually made of high-strength, wear-resistant metal material to ensure structural stability during long-term operation. The surface is specially treated to enhance the friction between the roller and the conveyor belt 10, prevent slippage, and ensure the continuity and stability of the rubber accelerator conveying. The outer surface of the electric drive roller 11 is connected to the conveyor belt 10. Each infrared radiator 12 is located above the conveyor belt 10. A hot air blower 9 is fixedly embedded on one side of the support cover 2.

[0025] As can be seen from the above description, this utility model has the following beneficial effects: the spiral feeder 5 can continuously convey the rubber accelerator, and it will be preheated synchronously by the arc-shaped electric heating plate 7. The electric heating guide plate 8 can guide the flow of the rubber accelerator and perform secondary drying. Then, the hot air from the hot air blower 9 will assist in drying. In addition, the electric drive roller 11 drives the conveyor belt 10 to send the rubber accelerator to the area below the infrared radiator 12 for deep drying. Finally, it will be discharged from the left end of the conveyor belt 10. The whole process can be carried out continuously without interruption of drying due to frequent feeding and unloading, thus improving drying efficiency and throughput per unit time. Example

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0027] like Figures 1-5 As shown, in a preferred embodiment, the hot air blower 9 includes an air inlet hood 901 fixedly embedded on one side of the support cover 2. An electric heating wire 902 and a blower 903 are fixedly installed on the inner wall of the air inlet hood 901. A ventilation mesh plate 904 is threadedly connected to the inner wall of the air inlet hood 901. The spiral feeding component 5 includes a drive rod 502 disposed inside the conveying cylinder 4. A spiral blade 503 is fixedly connected to the outer surface of the drive rod 502. Two bearings 504 are fixedly embedded in the inner wall of the conveying cylinder 4. The inner rings of the two bearings 504 are rotatably connected to the outer surfaces of both ends of the drive rod 502. A reduction motor 501 is fixedly installed on one side of the conveying cylinder 4. The output end of the speed motor 501 is fixedly installed at one end of the drive rod 502. Furthermore, the drive rod 502 is driven by the speed motor 501, which can drive the spiral blade 503 to rotate, so as to realize the stable conveying of the rubber accelerator along the conveying cylinder 4. During this process, the arc-shaped electric heating plate 7 preheats and dries the rubber accelerator. The bearing 504 ensures that the drive rod 502 runs smoothly, improving the conveying efficiency and stability. In addition, the blower 903 in the hot air blower 9 can blow air over the electric heating wire 902 to form hot air, which can be evenly sent into the support cover 2, which will assist the drying process and make the rubber accelerator dry more evenly and fully.

[0028] like Figures 1-5 As shown, in a preferred embodiment, two support seats 14 are fixedly connected to the upper surface of the support cover 2. The upper surfaces of the two support seats 14 are fixedly connected to the bottom surface of the conveying cylinder 4. The upper surface of the conveying cylinder 4 is fixedly connected to the injection hopper 6, which is located above the right end of the spiral blade 503. The upper surface of the electric heating guide plate 8 is provided with a guide groove. The electric heating guide plate 8 has a certain inclination angle. Two sets of support bases 13 are fixedly connected to the bottom surface of the conveying box 1. The bottom surfaces of the two sets of support bases 13 are provided with shock-absorbing pads. Furthermore, the support bases 13 and shock-absorbing pads can support the equipment and reduce the vibration of the equipment operation. The injection hopper 6 facilitates the injection of rubber accelerator. The electric heating guide plate 8 has a certain inclination angle. Its angle design allows the rubber accelerator to flow smoothly downwards without flowing too fast, thus ensuring its drying process.

[0029] The working process of this utility model is as follows:

[0030] In the later use of this drying equipment for purifying rubber accelerators, the rubber accelerator first enters the conveying cylinder 4 from the feeding hopper 6. Then, the reduction motor 501 drives the drive rod 502, which drives the spiral blade 503 to rotate, conveying the rubber accelerator along the conveying cylinder 4. During this process, the arc-shaped electric heating plate 7 on the top wall of the conveying cylinder 4 preheats and dries the rubber accelerator. The rubber accelerator enters the support cover 2 through the connecting pipe 3. The electric heating guide plate 8 inside the support cover 2 can guide the flow of the rubber accelerator and perform secondary heating and drying at the same time.

[0031] Next, the blower 903 inside the hot air blower 9 blows air over the electric heating wire 902 to form hot air, which is sent into the support cover 2 to assist in drying. Then, the rubber accelerator falls above the conveyor belt 10, and the electric drive roller 11 drives the conveyor belt 10 to rotate. Then, the infrared radiator 12 heats the rubber accelerator above the conveyor belt 10 through infrared radiation, and the rubber accelerator is deeply dried from above. Finally, it is discharged through the left end of the conveyor belt 10. This is the working process and working principle of the device.

[0032] In terms of circuit structure, the drive and control circuits are common and mature technologies. Those skilled in the art can select appropriate circuit components to build the circuit according to the power requirements and control requirements of the equipment. For the power supply components, common general-purpose power supply equipment on the market can be used, as long as it meets the voltage and current requirements of the equipment. No special design is required. In addition, the electrical components in this application are all common electrical equipment in the prior art. This application will not elaborate on their models or internal structures. Finally, the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
