Description

Technical Field

[0001] This application relates to the field of deweighting towers, and more particularly to a deweighting tower for rubber production. Background Technology

[0002] In the rubber production process, butadiene is the core raw material. Liquid butadiene needs to undergo dehydration and degravimetric analysis to remove impurities before it can undergo polymerization. Afterward, it is formulated into a rubber solution, mixed with demineralized water, and coagulated. Finally, the finished product is obtained through dehydration and briquetting.

[0003] During this process, steam and cold air are introduced into the deweighting tower to heat and cool the raw materials. However, when steam or cold air is introduced into the deweighting tower, the contact with the raw materials is not uniform, resulting in uneven heating and cooling effects, i.e., poor deweighting effect, which has a certain impact on rubber production. Summary of the Invention

[0004] To improve the deweighting effect, this application provides a deweighting tower for rubber production.

[0005] The technical solution for a deweight removal tower used in rubber production provided in this application is as follows:

[0006] A deweighting tower for rubber production includes a tower body with a deweighting chamber inside. An operating gap is formed between the tower body and the deweighting chamber. The tower body has a steam inlet and a steam outlet, both connected to the operating gap. The tower body also has a cold air inlet and a cold air outlet, both connected to the operating gap. A flow equalization box is located within the operating gap and surrounds the deweighting chamber. The flow equalization box has several groups of air inlets. Ventilation plates are rotatably mounted at the air inlets of the flow equalization box. A drive unit is installed inside the tower body to drive all ventilation plates to rotate synchronously.

[0007] By adopting the above technical solution, when steam enters and fills the working gap, the drive unit drives all the venting plates to rotate, the air inlets open, and steam flows into the equalization box from all the air inlets to heat the peripheral walls of the deweighting chamber. This method can make the heating of the material more uniform and improve the desorption effect of the polymerization inhibitor. Afterwards, the steam outlet is opened to discharge the steam and the venting plates are closed. Then, cold air is introduced into the chamber through the cold air inlet. When the cold air fills the working gap, the drive unit drives all the venting plates to rotate again, and the cold air enters evenly from all the air inlets and flows inward to achieve uniform cooling of the raw materials. In this way, uniform heating and cooling of the raw materials are achieved, which helps to improve the deweighting effect.

[0008] Preferably, the flow equalization box is rectangular in shape, and four vertical surfaces are formed on the flow equalization box. The air inlet groups are distributed along the vertical direction on the corresponding vertical surfaces. The air inlet groups include a number of horizontally distributed air inlets. The flow equalization box is rotatably equipped with multiple rotating rods corresponding to the number of air inlet groups. The rotating rods pass through all the air inlets in the same group in sequence. The vent plate is fixed on the rotating rods. The driving component is used to drive all the rotating rods to rotate synchronously.

[0009] By adopting the above technical solution, all rotating rods are driven by the driving component to rotate, thereby realizing the rotation of all vent plates. This allows all air inlets to open synchronously, ensuring that steam can enter evenly and surround the periphery of the deweighting chamber.

[0010] Preferably, the driving component is configured as a thermal expansion airbag, and four thermal expansion airbags are arranged corresponding to four vertical surfaces. The thermal expansion airbags are located at the bottom of the tower body. Four linear racks are arranged vertically inside the tower body, corresponding one-to-one with the thermal expansion airbags. All rotating rods in the same vertical surface have a gear fixed coaxially at the same end. The linear racks mesh with the corresponding gears, and the lower end of the linear racks is connected to the corresponding thermal expansion airbags.

[0011] By adopting the above technical solution, when high-temperature steam enters the working gap, due to the high temperature of the steam, the steam will first fill the top of the working gap and then gradually spread to the bottom of the tower. When the high-temperature steam comes into contact with the thermal expansion bladder, the thermal expansion bladder expands, causing the linear rack to rise and fall, driving all gears to rotate, which in turn causes the ventilation plate to flip, realizing the synchronous opening of all air inlets.

[0012] Preferably, the steam inlet is located on the upper side of the tower body, and the steam outlet is also located on the upper side of the tower body.

[0013] By adopting the above technical solution, the steam inlet is set on the upper side of the tower body. When high-temperature steam is introduced into the tower body, it will first accumulate at the top of the tower body and then gradually fill downwards until the high-temperature steam comes into contact with the thermal expansion bladder. In this way, it can be ensured that the thermal expansion bladder will only expand when the high-temperature steam fills the working gap. If the steam inlet is set at the bottom of the tower body, the thermal expansion bladder will expand when the steam enters the tower body, but at this time the steam content in the tower body is low, and it is impossible to achieve uniform heating of the de-weighting chamber.

[0014] Preferably, the cold air inlet is located on the upper side of the tower body, and the cold air outlet is located on the lower side of the tower body.

[0015] By adopting the above technical solution, since cold air flows downwards, if the cold air inlet is located on the lower side of the tower body, the cold air will concentrate on the lower side of the working gap and then gradually flow upwards. Before the working gap is completely filled by the cold air, the thermal expansion bladder will contract under the action of the cold air, causing the ventilation plate to rotate and the cold air to enter the flow equalization box. At this time, it will lead to uneven cooling effect on the de-weighting chamber. Therefore, by setting the cold air inlet on the upper side of the tower body and filling it inwards to ensure a large flow rate, the cold air can be filled by the time it reaches the bottom of the working gap. At this time, the thermal expansion bladder contracts, all ventilation plates open, and the cold air can enter the flow equalization box evenly, achieving uniform cooling of the de-weighting chamber.

[0016] Preferably, a guide plate is provided inside the tower body, and a smooth guide portion is formed on the lower side of the linear rack, the guide portion being inserted into and slidingly engaged with the guide plate.

[0017] By adopting the above technical solution, the guide plate and the linear rack are inserted and slidably matched to achieve the guiding effect on the linear rack, which helps to improve the stability of the linear rack lifting.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. A flow equalization box is installed inside the deweighting tower. When steam is introduced into the tower body, it will be temporarily stored in the working gap. Then, the driving component drives the vent plate on the flow equalization box to rotate and open, so that the steam enters the flow equalization box synchronously, so that the periphery of the deweighting chamber can be heated evenly, and the material can be heated evenly, thus improving the deweighting effect.

[0020] 2. The thermal expansion bladder expands when steam fills the bottom of the tower, driving the lifting rod to rise. During this process, all rotating rods of the connecting rod rotate, causing the ventilation plate to rotate. When the steam is discharged, the thermal expansion bladder gradually contracts to its normal state, and the ventilation plate returns to its original position. In addition, when cold air is introduced, the thermal expansion bladder contracts, causing the lifting rod to descend, which drives the connecting rod to rotate, and the ventilation plate will also open, thus achieving the cooling operation of the unloading chamber.

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses a deweighting tower for rubber production.

[0026] Reference Figure 1 and Figure 2 The deweighting tower for rubber production includes a tower body 1, a deweighting chamber 2 installed inside the tower body 1, an inlet 11 and an outlet 12 formed on the tower body 1, the inlet 11 is connected to the upper end of the deweighting chamber 2, and the outlet 12 is connected to the lower end of the deweighting chamber 2. A flow equalization box 3 is installed on the periphery of the deweighting chamber 2 on the tower body 1, and an operating gap 4 is formed between the tower body 1 and the flow equalization box 3. The flow equalization box 3 is cuboid in shape and has four vertical surfaces. Since the structure on the four vertical surfaces is the same, one of the vertical surfaces will be used as an example for explanation.

[0027] The flow equalization box 3 is located on a vertical plane and has several groups of air inlets. All groups of air inlets are distributed vertically on the vertical plane, and each group of air inlets contains multiple air inlets 5 distributed horizontally, that is, the air inlets 5 are distributed in a rectangular array on the vertical plane. Each air inlet 5 of the flow equalization box 3 is rotatably connected to a vent plate 6. The tower body 1 is equipped with a drive unit 7 that drives all the vent plates 6 to rotate synchronously. The upper side of the tower body 1 has a steam inlet 13 and a steam outlet 14; the lower side of the tower body 1 has a cold air inlet 15 and a cold air outlet 16.

[0028] After the material is fed into the deweighting chamber 2, high-temperature steam is introduced through the steam inlet 13. The high-temperature steam gradually fills the working gap 4. The driving component 7 is used to rotate all the ventilation plates 6 and open the air inlet 5. At this time, the steam enters the flow equalization box 3 through the air inlet 5. The steam can then contact the outer wall of the deweighting chamber 2 evenly to heat the material. This method makes the material heating more uniform and helps to improve the desorption effect of the polymerization inhibitor. After heating is completed, the steam inlet 13 is closed and the steam outlet 14 is opened to discharge the steam. Then, the cold air inlet 15 is opened to introduce cold air into the interior for cooling.

[0029] In addition, the flow equalization box 3 is rotatably connected to the number of air inlet groups, and the rotating rods 8 correspond to all the air inlets 5 in the same air inlet group. The rotating rods 8 pass through all the corresponding air inlets 5 in sequence. The corresponding ventilation plate 6 is coaxially fixed with the rotating rods 8, that is, the ventilation plate 6 rotates with the rotation of the rotating rods 8. The driving component 7 drives all the rotating rods 8 to rotate. The driving component 7 is set as a thermal expansion air bladder 71. The thermal expansion air bladder 71 is fixedly installed at the bottom of the tower body 1. A linear rack 9 is raised and lowered inside the tower body 1. The linear rack 9 is set in the vertical direction. The lower end of the linear rack 9 is fixed to the thermal expansion air bladder 71. All the rotating rods 8 in the same vertical plane are coaxially fixed with gears 10. The linear rack 9 and all the gears 10 mesh.

[0030] A guide plate 17 is installed inside the tower body 1. A smooth guide part is formed at the lower end of the linear rack 9. The guide part is inserted and slidably engaged with the guide plate 17 to guide the lifting and lowering of the linear rack 9.

[0031] When steam enters the tower body 1, because the steam inlet 13 is on the upper side of the tower body 1 and the high-temperature gas will move upward, the steam will gradually spread to the lower side of the tower body 1 until it comes into contact with the thermal expansion bladder 71. Utilizing the principle of thermal expansion and contraction, the thermal expansion bladder 71 will expand under the high temperature of the steam, causing the linear rack 9 to rise, and the gear 10 to rotate, thereby driving the rotating rod 8 to rotate, realizing the rotation of all the ventilation plates 6, that is, realizing the opening of the air inlet 5. At this time, the steam will enter the flow equalization box 3 evenly from all the air inlet 5 to heat the deweighting chamber 2.

[0032] Similarly, during cooling, the cold air inlet 15 is opened to allow cold air to enter. After the thermal expansion airbag 71 comes into contact with the cold air, it will contract. At this time, the linear rack 9 will drive the ventilation plate 6 to flip downward, opening the air inlet 5. The cold air will enter the air inlet 5 to achieve the cooling operation of the unloading chamber 2.

[0033] In this design, the steam inlet 13 is located on the upper side of the tower body 1. When high-temperature steam is introduced into the tower body 1, it will first accumulate at the top of the tower body 1 and then gradually fill downwards until the high-temperature steam comes into contact with the thermal expansion bladder 71. In this way, it can be ensured that the thermal expansion bladder 71 will only expand when the high-temperature steam fills the working gap. If the steam inlet is located at the bottom of the tower body 1, the thermal expansion bladder 71 will expand when the steam enters the tower body 1. However, at this time, the steam content in the tower body 1 is low and cannot achieve uniform heating of the de-weighting chamber 2.

[0034] In addition, since cold air flows downwards, if the cold air inlet is located on the lower side of the tower body 1, the cold air will concentrate on the lower side of the working gap 4 and then gradually flow upwards. Before the cold air fills the working gap, the thermal expansion bladder 71 will contract under the action of the cold air, causing the ventilation plate 6 to rotate and the cold air to enter the flow equalization box 3. At this time, it will lead to uneven cooling effect on the de-weighting chamber 2. Therefore, the cold air inlet is set on the upper side of the tower body 1 and filled inwards to ensure a large inlet rate. This will ensure that the cold air fills the working gap 4 when it flows to the bottom. At this time, the thermal expansion bladder 71 contracts, all ventilation plates 6 open, and the cold air can enter the flow equalization box 3 evenly, achieving uniform cooling of the de-weighting chamber 2.

[0035] In practice, corresponding to the four vertical surfaces of the flow equalization box 3, there are also four linear racks 9, and one thermal expansion airbag 71 is provided. The thermal expansion airbag 71 is ring-shaped and is used to drive the four linear racks 9 to rise and fall.

[0036] The implementation principle of a deweighting tower for rubber production according to an embodiment of this application is as follows: Material enters the deweighting chamber 2, and steam is introduced into the steam inlet 13 until the working gap 4 is filled. At this time, the thermal expansion bladder 71 expands, causing the linear rack 9 to rise, driving the gear 10 to rotate, thereby causing the ventilation plate 6 to flip, simultaneously opening all the air inlets 5. Steam enters the flow equalization box 3 simultaneously and evenly from all the air inlets 5, thus ensuring uniform heating of the material. Afterwards, the steam is discharged from the steam outlet 14. Cold air is introduced from the cold air inlet 15. When the cold air flows to the bottom of the working gap 4, it has basically filled the working gap 4. The thermal expansion bladder 71 contracts, similarly driving the ventilation plate 6 to rotate, causing all the air inlets 5 to open, and cold air enters the flow equalization box 3 evenly, achieving uniform cooling of the material. This method of uniform heating and cooling of the material helps improve the deweighting effect, thereby helping to improve the quality of subsequent rubber molding.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
