Description

Technical Field

[0001] The utility model belongs to the technical field of styrene-butadiene rubber preparation, in particular to a styrene-butadiene rubber continuous preparation device. Background Art

[0002] Styrene butadiene rubber is also known as polystyrene butadiene copolymer. Its physical properties, processing properties and product performance are close to those of natural rubber. It is widely used in the production of tires, tapes, hoses, wires and cables, medical devices and various rubber products. During the production or stacking process of styrene butadiene rubber raw material powder, due to its density, it is easy to accumulate heat and cannot be put into use quickly. It usually needs to be spread over a large area for free heat dissipation, which seriously affects production efficiency. Therefore, some refrigeration equipment that can quickly dissipate heat from rubber powder has appeared on the market.

[0003] For example, patent application number CN202022617435.4 discloses a cooling device for preparing graphene conductive styrene-butadiene rubber, including a cooling tank, a cooling water pipe, a circulating water refrigerator, a mixing rod and a brush plate, wherein a filling hopper is provided on the upper part of the cooling tank, and a discharge pipe is connected to one end of the cooling tank; a ring-shaped cooling water pipe is provided inside the cooling tank, and one end of the cooling water pipe passes through the cooling tank and is connected to the circulating pipe, and the other end of the cooling water pipe is connected to the water inlet pipe through a water pump, and a circulating water refrigerator is provided between the circulating pipe and the water inlet pipe; a stirring rod is also provided inside the cooling tank, and a mixing rod is connected to the upper part of the stirring rod, and a brush plate is connected to the bottom of the stirring rod. In the utility model, cooling water circulates in the cooling water pipe, and under the extraction action of the pump body, the cooling water in the cooling water pipe can be extracted into the circulating water refrigerator, so as to cool down the cooling water that takes away the heat of the powder in the cooling tank again.

[0004] The prior art uses a spiral cooling water pipe and a mixing rod to quickly remove the internal heat of the rubber powder raw material, thereby improving the cooling efficiency. However, there are still certain deficiencies in the overall use process: the density of the rubber powder is high and the thermal conductivity is low. Although the prior art stirs the rubber powder through a mixing rod to loosen the rubber powder, the overall stirring amplitude and coverage area are small, and most of the rubber powder still cannot smoothly contact the refrigeration structure, resulting in the inability to improve the overall cooling efficiency, which affects the production efficiency. Utility Model Content

The utility model, through the arrangement of the spiral shaft and the bending rod and the first connecting inner tube and the convex panel, enables the rubber powder to be stirred over a large area, and can fully contact with the cooling and heat-conducting structure during the stirring process, effectively improving the cooling efficiency and quality of the rubber powder as a whole.

The provision of the feed port and the discharge port enables the equipment to automatically complete the loading and unloading process.

[0009] Preferably, each of the convex panels is provided with a second communicating inner tube, and both ends of the second communicating inner tube are connected to the first communicating inner tube. The provision of the second communicating inner tube improves the overall cooling effect of the convex panel.

[0022] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0023] Embodiment 1:

[0024] refer to Figure 1-6 A continuous preparation device for styrene-butadiene rubber comprises a cylinder 10 and a cylinder cover 11. The cylinder cover 11 is arranged on the upper end surface of the cylinder 10, and a ventilation shaft 13 is rotatably arranged on the end surface of the cylinder cover 11. A first connecting disk 21 is connected to the lower end surface of the ventilation shaft 13, a spiral shaft 19 is connected to the bottom of the first connecting disk 21, and a second connecting disk 22 is connected to the bottom of the spiral shaft 19. A ventilation inner tube 20 connected to the second connecting disk 22 is arranged inside the spiral shaft 19, and a plurality of bending rods 23 are evenly arranged on the outer circular surfaces of the first connecting disk 21 and the second connecting disk 22 along the circumferential direction, a first connecting inner tube 25 is arranged inside the bending rod 23, and a plurality of convex panels 24 are arranged on the plurality of bending edges of the bending rod 23.

[0025] Specifically, the cylinder 10 is used to place the rubber raw material, and the top is open, and the cylinder cover 11 is used to seal it. When the rubber raw material needs to be cooled quickly, the staff can place the rubber raw material inside the cylinder 10 and then start the equipment.

[0026] The ventilation shaft 13 will drive the first connecting disk 21 at the bottom to rotate, thereby driving the spiral shaft 19 connected to the bottom of the first connecting disk 21 to rotate. The spiral shaft 19 is spiral in shape as a whole and can stir the raw materials. The rotation of the spiral shaft 19 will drive the second connecting disk 22 on the bottom end to rotate. At this time, the first connecting disk 21 and the second connecting disk 22 will both be in a rotating state. The upper and lower ends of the plurality of bending rods 23 are connected to the outer circumferential surfaces of the first connecting disk 21 and the second connecting disk 22. The plurality of bending rods 23 are in a bent "" shape as a whole. During the rotation of the first connecting disk 21 and the second connecting disk 22, the plurality of bending rods 23 will be driven to rotate synchronously. The range of the bent bending rods 23 can cover most of the positions inside the cylinder 10, so that the raw material powders at various positions inside the cylinder 10 can be effectively moved, so that the raw materials are in a state of rapid flow.

[0027] At this time, the ventilation inner tube 20 can inject the cooled gas into the second connecting plate 22 through the hose connected to the outside, and the cooling gas flowing into the second connecting plate 22 will flow into the multiple first connecting inner tubes 25 connected thereto, so as to perform cooling treatment on the bending rod 23. In this solution, the bending rod 23 is made of a metal material with a high thermal conductivity, so the bending rod 23 can quickly cool the raw material by continuously contacting the raw material.

[0028] During the rotation of the bending rod 23, the multiple convex panels 24 on the bending edge will also be driven to rotate. The convex panels 24 are made of the same material as the bending rod 23, and are made of metal materials with high thermal conductivity. The refrigeration process is completed synchronously with the bending rod 23. The convex panels 24 can increase the contact area with the raw materials, so that the raw materials can be better moved, so that the raw materials are in a fast flow state, and the refrigeration temperature can be quickly transferred to various places inside the raw materials. In this solution, there is no specific restriction on the number and arrangement shape of the convex panels 24, and they can be set according to actual conditions;

[0029] The cold air will gradually flow upward until it flows into the first connecting plate 21, and finally be discharged outward through the first connecting plate 21. In this relationship, due to the gravity of the raw materials, the amount ratio of the raw materials at the bottom of the cylinder 10 is much higher than that at the top. Therefore, the cold air is drawn upward from the second connecting plate 22, which can better utilize the refrigerant gas and improve the refrigeration effect.

[0030] refer to Figure 1An air inlet port 14 is provided at the center of the end surface of the ventilation shaft 13, and the air inlet port 14 is communicated with the ventilation inner tube 20. A plurality of exhaust ports 15 are provided outside the air inlet port 14 inside the ventilation shaft 13, and the exhaust ports 15 are communicated with the first connecting disk 21.

[0031] Specifically, the air inlet pipe opening 14 is externally connected to a condenser that can cool the gas. The condenser is a prior art and will not be elaborated in this article, so that the refrigerated gas can be poured into the interior of the ventilation inner tube 20 connected thereto. In this relationship, a connecting pipeline is provided in the middle of the first connecting plate 21, so that the air inlet pipe opening 14 and the ventilation inner tube 20 can be smoothly connected; when the cold air flows to the first connecting plate 21 through the first connecting inner tube 25, the first connecting plate 21 can discharge the gas with increased temperature through the top end of the exhaust pipe opening 15 through a plurality of exhaust pipe openings 15 connected thereto.

[0032] refer to Figure 1 A first gear 16 is arranged on the outer circumferential surface of the ventilation shaft 13, a second gear 17 is rotatably arranged on one side of the first gear 16, the first gear 16 and the second gear 17 are meshed and transmitted with each other, a driving motor 18 is fixedly arranged above the second gear 17, and the output end of the driving motor 18 is connected to the end surface of the second gear 17.

[0033] Specifically, the drive motor 18 is a prior art and will not be elaborated in detail herein. The output end of the drive motor 18 can drive the second gear 17 to rotate, thereby driving the first gear 16 meshing therewith to rotate, thereby driving the ventilation shaft 13 at the center of the first gear 16 to rotate, so that the raw materials inside the cylinder 10 can be smoothly stirred and the refrigeration process can be completed.

[0034] refer to Figure 4 A second communicating inner tube 27 is disposed in each of the convex panels 24 , and both ends of the second communicating inner tube 27 are connected to the first communicating inner tube 25 .

[0035] Specifically, the cross-section of the second connecting inner tube 27 is U-shaped, and both ends of the second connecting inner tube 27 are interconnected with the first connecting inner tube 25. When gas flows inside the first connecting inner tube 25, it can flow into the second connecting inner tube 27, thereby improving the cooling efficiency of the convex panel 24, so that the convex panel 24 can improve the cooling effect while improving the stirring effect.

[0036] refer to Figure 4 A waist-shaped hole 26 is provided on the end surface of the convex panel 24 .

[0037] Specifically, the waist-shaped hole 26 is arranged on the middle end face of the convex panel 24, and the specific size is not limited. On the one hand, it is arranged in the middle of the convex panel 24 so that part of the raw materials can flow to one side through the waist-shaped hole 26 during the stirring process, thereby reducing the resistance to stirring. On the other hand, the cooling of the convex panel 24 as a whole is faster, the contact area between the convex panel 24 and the raw materials is increased, and the overall cooling efficiency is also effectively improved.

[0038] refer to Figure 3-5 A feed port 12 is provided on the end surface of the cylinder cover 11 , and a discharge port 29 is provided at the bottom of the cylinder body 10 below the cylinder cover 11 .

[0039] Specifically, the feed port 12 is used to pour the raw materials into the cylinder 10, and the discharge port 29 can discharge the refrigerated raw materials to the outside.

[0040] Embodiment 2:

[0041] On the basis of or different from the first embodiment, reference Figure 6 A guide cone block 28 is provided on the bottom end surface of the second connecting plate 22.

[0042] Specifically, the guide cone block 28 is cone-shaped as a whole, and is arranged just above the discharge port 29 and is interconnected with the bottom of the second connecting disk 22. When the discharge port 29 needs to discharge, under the action of the second connecting disk 22, the guide cone block 28 can be driven to rotate rapidly, so that the raw materials flowing to the bottom of the cylinder 10 ready to be discharged can be guided and stirred to form a vortex, thereby improving the discharge efficiency of the raw materials.
