Description

Technical Field

[0001] This utility model relates to the field of butyl rubber, and in particular to a butyl rubber regeneration desulfurization device. Background Technology

[0002] In the field of butyl rubber recycling, efficient desulfurization of waste rubber is the core step in achieving recycling. Traditional desulfurization devices generally suffer from uneven distribution of desulfurizing agents and low mixing efficiency.

[0003] Most existing equipment uses a static method of adding desulfurizing agent through fixed nozzles or pipes, and then relies on gravity or simple stirring to mix the desulfurizing agent with it. However, after butyl rubber is heated and softened, it is in a highly elastic or semi-molten state, and its viscosity increases significantly. This causes the desulfurizing agent to easily accumulate in local areas (such as the bottom of the tank or the upper layer of material), and cannot penetrate into the rubber matrix to mix with it evenly. In addition, the fixed-position material distribution method will also lead to uneven distribution of desulfurizing agent between the rubbers after preliminary treatment, resulting in insufficient local reaction inside the reaction tank, low desulfurization efficiency, and directly leading to incomplete desulfurization.

[0004] Therefore, it is necessary to provide a new butyl rubber regeneration desulfurization device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a butyl rubber regeneration desulfurization device.

[0006] This utility model provides a butyl rubber regeneration desulfurization device comprising: a reaction tank, wherein a feed port is provided at the upper end of the reaction tank, a discharge pipe is provided at the lower end of the reaction tank, a support frame is fixedly connected to the top wall of the reaction tank, and an adjustment seat is provided between the support frames; a uniform addition mechanism, wherein the uniform addition mechanism includes a shaft tube, a rotating drum is provided at the middle position of the adjustment seat, the shaft tube is rotatably connected to the rotating drum, a bottom cloth strip is fixedly connected to the lower end of the shaft tube, a gear ring is fixedly connected to the upper end of the shaft tube, a gear is provided on one side of the gear ring, the gear meshes with the gear ring, and a small motor is provided on the adjustment seat, the output shaft of the small motor is fixedly connected to the gear.

[0007] Preferably, the bottom fabric strip has multiple fabric openings, which are arranged at equal intervals.

[0008] Preferably, the adjusting seat is provided with a mounting bracket, and the small motor is fixedly mounted on the mounting bracket.

[0009] Preferably, the adjusting seat is provided with a central frame, and an outer tube is fixedly connected to the top of the central frame. A rotary joint is installed between the outer tube and the top end of the shaft tube.

[0010] Preferably, both ends of the upright frame are provided with through slots, a vertical rod is fixedly connected to one end of the through slot, and a drive shaft is rotatably connected to the other end of the through slot. A main motor is installed at the top of the upright frame, and the output end of the main motor is fixedly connected to the drive shaft.

[0011] Preferably, one end of the adjusting seat is slidably connected to the vertical rod, the drive shaft is a reciprocating lead screw, and the other end of the adjusting seat is provided with a threaded opening, which is threadedly connected to the drive shaft.

[0012] Compared with related technologies, the butyl rubber regeneration desulfurization device provided by this utility model has the following beneficial effects:

[0013] 1. This utility model delivers the desulfurizing agent into the shaft tube through an external pipe, and then discharges it evenly through the fabric strip at the bottom. At the same time, the output end of the small motor drives the gear to rotate the gear ring, so that the shaft tube and the bottom fabric strip rotate synchronously. When the fabric strip rotates with the shaft tube, the desulfurizing agent is squeezed out from the equidistant fabric outlets and forms a ring distribution area. This avoids the problem of local accumulation and uneven mixing caused by traditional single-point addition, and allows the desulfurizing agent to be effectively mixed with the rubber, assisting the rubber in chain-breaking desulfurization.

[0014] 2. This utility model drives the drive shaft to rotate through the output end of the main motor. The adjusting seat moves up and down along the vertical rod, and the adjusting seat drives the shaft tube to move accordingly, so as to realize the synchronous adjustment of the height of the fabric strip. This allows the desulfurizing agent extruded from the fabric strip to be fully and evenly distributed inside the reaction tank, and further fully mixed with the softened rubber. The desulfurization reaction can be completed efficiently and quickly inside the reaction tank. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 3 A butyl rubber regeneration desulfurization device includes: a reaction tank 1, a feeding port 2 at the upper end of the reaction tank 1, a discharge pipe 21 at the lower end of the reaction tank 1, a support frame 3 fixedly connected to the top wall of the reaction tank 1, and an adjusting seat 4 between the support frames 3; a uniform addition mechanism, which includes a shaft tube 41, a rotating drum at the middle of the adjusting seat 4, the shaft tube 41 being rotatably connected to the rotating drum, a bottom cloth strip 42 fixedly connected to the lower end of the shaft tube 41, a gear ring 43 fixedly connected to the upper end of the shaft tube 41, a gear 44 on one side of the gear ring 43, the gear 44 meshing with the gear ring 43, and a small motor 45 on the adjusting seat 4, the output shaft of the small motor 45 being fixedly connected to the gear 44.

[0021] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the bottom fabric strip 42 has multiple fabric openings, which are arranged at equal intervals.

[0022] It should be noted that: the output end of the small motor 45 drives the gear 44 to rotate the gear ring 43, so that the shaft tube 41 and the bottom cloth strip 42 rotate synchronously, thereby achieving a uniform circumferential distribution of the desulfurizing agent;

[0023] The equidistantly arranged fabric nozzles on the bottom fabric strip 42 allow the desulfurizer to form a uniform linear distribution during extrusion. Combined with the rotational movement of the shaft tube 41, an annular desulfurizer distribution area can be formed in the reaction tank 1, avoiding the local accumulation problem caused by traditional single-point addition and ensuring that the contact area between the desulfurizer and the rubber is maximized.

[0024] refer to Figure 2 and Figure 3 As shown, the adjusting seat 4 is equipped with a mounting bracket, and the small motor 45 is fixedly mounted on the mounting bracket.

[0025] refer to Figure 2 and Figure 3 As shown, the adjusting seat 4 is provided with a central frame, and an outer tube 51 is fixedly connected to the top of the central frame. A rotary joint 5 is installed between the outer tube 51 and the top tube head of the shaft tube 41.

[0026] It should be noted that the outer pipe 51 is connected to the shaft pipe 41 through the rotary joint 5, which allows the shaft pipe 41 to maintain continuous delivery of desulfurizing agent during rotation, ensuring a stable supply of desulfurizing agent during dynamic mixing.

[0027] refer to Figure 1 As shown, both ends of the upright frame 3 are provided with through slots. A vertical rod 6 is fixedly connected in the through slot at one end, and a drive shaft 61 is rotatably connected in the through slot at the other end. A main motor 7 is installed at the top of the upright frame 3, and the output end of the main motor 7 is fixedly connected to the drive shaft 61.

[0028] It should be noted that the drive shaft 61 driven by the main motor 7 is a reciprocating lead screw. Its threaded connection with the adjusting seat 4 can convert the rotational motion into linear motion. By controlling the main motor 7, the adjusting seat 4 can move up and down along the vertical rod 6, driving the shaft tube 41 and the bottom cloth strip 42 to move in different height ranges in the reaction tank 1, so that the desulfurizing agent can cover the upper, middle and lower layers of rubber in the reaction tank 1, solving the problem of uneven mixing caused by traditional fixed height addition.

[0029] refer to Figure 1 As shown, one end of the adjusting seat 4 is slidably connected to the vertical rod 6, the drive shaft 61 is a reciprocating lead screw, and the other end of the adjusting seat 4 is provided with a threaded port, and the other end of the adjusting seat 4 is threadedly connected to the drive shaft 61.

[0030] It should be noted that: one end of the adjusting seat 4 is slidably connected to the vertical rod 6, and the other end is threadedly connected to the drive shaft 61, to ensure that the adjusting seat 4 remains stable during the lifting and lowering process, thereby ensuring the uniformity and stability of the desulfurizing agent distribution.

[0031] The working principle of the butyl rubber regeneration desulfurization device provided by this utility model is as follows: After the waste butyl rubber is crushed, pretreated and heated, it is put into the reaction tank 1 through the feeding port 2. The desulfurizing agent is transported to the shaft tube 41 through the external pipe 51 and is evenly extruded through the feeding port of the bottom feeding strip 42. At the same time, the small motor 45 is started, and its output end drives the gear 44 to drive the gear ring 43 to rotate, so that the shaft tube 41 and the bottom feeding strip 42 rotate synchronously, so as to achieve the circumferential uniform distribution of the desulfurizing agent.

[0032] Simultaneously, the main motor 7 is started, causing its output end to drive the drive shaft 61 (reciprocating screw) to rotate, which in turn drives the adjusting seat 4 to move up and down along the vertical rod 6. The adjusting seat 4 drives the shaft tube 41 to move accordingly, thereby synchronously adjusting the height of the fabric strip 43. The desulfurizing agent extruded from the fabric strip 43 can be fully and evenly distributed inside the reaction tank 1, allowing it to fully mix with the softened rubber and complete the desulfurization reaction inside the reaction tank 1. The product is then discharged through the discharge pipe 21.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
