Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a kneading cylinder and a butyl rubber kneading machine. Background Technology

[0002] The butyl rubber kneader is a mixing device specifically designed for high-viscosity, high-elasticity butyl rubber. It achieves material mixing, kneading, degassing, and dispersion through differential shearing with dual blades. Butyl rubber becomes very viscous and has poor fluidity at low temperatures. Therefore, butyl rubber needs to be kept at a high temperature when it is mixed and stirred in the kneading cylinder of the butyl rubber kneader, otherwise it may cause motor current overload or even damage the equipment.

[0003] The kneading cylinder of a large butyl rubber kneader on the market includes a cylinder liner forming the circumferential sidewalls of the cylinder and a cylinder plate forming the endwalls of the cylinder. However, heating jackets are generally only installed on the cylinder liner, or heating components are installed on the paddle shaft, screw shaft, or screw barrel to ensure that the butyl rubber is in a high-temperature state. On the cylinder plates at both ends of the kneading cylinder, there are sealing structures for sealing the connection between the paddle shaft and the cylinder plate, or the connection between the screw and the cylinder plate. Due to the presence of these sealing structures, heating components are usually not installed on the cylinder plates to reduce the impact of heat on these sealing structures. However, the cylinder plate area of ​​the kneading cylinder in a large butyl rubber kneader is very large. If the heating components are ignored, it will inevitably affect the uniform heating of the butyl rubber in the kneading cylinder, thus adversely affecting the mixing of the butyl rubber. Utility Model Content

[0004] This utility model provides a kneading cylinder and a butyl rubber kneading machine, aiming to solve the problem that the cylinder plate of the existing large butyl rubber kneading cylinder cannot be equipped with heating components due to the limitation of the sealing structure, resulting in uneven heating of butyl rubber.

[0008] Multiple sealing assemblies are provided, each including a sealing sleeve and a heat-conducting sleeve for the agitator shaft or the conveyor shaft to pass through. The sealing sleeve is disposed on the inner circumferential side of the heat-conducting sleeve and is used to seal the connection between the agitator shaft or the conveyor shaft and the heat-conducting sleeve. The heat-conducting sleeve is arranged around the axis of the through hole and is fixedly and sealingly connected to the cylinder plate. The heat-conducting sleeve is provided with a cold-conducting part for connecting to a cold source. The cold-conducting part is arranged around the axis of the heat-conducting sleeve and is located on the outer circumferential side of the sealing sleeve to transfer cold energy to the sealing sleeve.

[0009] In some embodiments of the first aspect, the cooling part is a liquid-containing cavity located inside the sleeve wall of the heat-conducting sleeve.

[0011] The liquid-containing cavity includes multiple separate cavities, which are not interconnected. The multiple separate cavities are arranged around the axis of the heat-conducting sleeve, and each separate cavity is connected to a liquid inlet and a liquid outlet.

[0012] In some embodiments of the first aspect, the cooling section is an annular cooling pipe, which is wound around the outer peripheral wall of the heat-conducting sleeve, and the annular cooling pipe is used to connect to an external liquid cooling circulation mechanism.

[0015] The second heating element is disposed on the peripheral sidewall of the cylinder body, and the second heating element is used to heat the peripheral sidewall of the cylinder plate.

[0016] In some embodiments of the first aspect, the first heating element includes a plurality of baffle-type heating elements, which are arranged side by side on the outer wall of the cylinder plate to cover the outer wall of the cylinder plate.

[0017] In some embodiments of the first aspect, the second heating part includes a plurality of heating jackets, all of which are sleeved on the outer peripheral sidewall of the cylinder body, and the plurality of heating jackets are coaxially arranged to cover the outer peripheral sidewall of the cylinder body.

[0018] In some embodiments of the first aspect, the outer wall of the heating assembly is covered with an insulation layer.

[0019] In some embodiments of the first aspect, a structural reinforcing plate is fixed inside the cylinder, and the structural reinforcing plate is connected and fixed to the two cylinder plates.

[0020] The second aspect of this utility model provides a butyl rubber type kneader, comprising:

[0021] The kneading cylinder described in the first aspect;

Furthermore, the heat-conducting sleeve is provided with a cooling section for connecting to a cold source. This cooling section surrounds the periphery of the heat-conducting sleeve.

This avoids creep and aging of the sealing material due to prolonged high temperatures. Therefore, the design of this embodiment balances the heating and sealing of the cylinder plate, allowing the butyl rubber to be uniformly heated within a well-sealed kneading cylinder.

[0037] This utility model provides a kneading cylinder and a butyl rubber kneading machine to solve the technical problem that the cylinder plate of the existing large butyl rubber kneading cylinder cannot be equipped with heating components due to the limitation of the sealing structure, resulting in uneven heating of butyl rubber.

[0038] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0039] Please see Figure 1 , Figure 4 and Figure 5 The present invention provides a kneading cylinder, comprising:

[0040] The cylinder body 1 has cylinder plates 10 at both ends in the axial direction. One cylinder plate 10 is provided with a through hole 100 for the stirring shaft 4 and the conveying shaft 5 to pass through.

[0041] Heating component 2 is disposed on the peripheral sidewall of cylinder 1 and cylinder plate 10;

[0042] The sealing assembly 3 includes a sealing sleeve 30 and a heat-conducting sleeve 31 for the stirring shaft 4 and the conveying shaft 5 to pass through. The sealing sleeve 30 is disposed on the inner circumferential side of the heat-conducting sleeve 31 and is used to seal the connection between the stirring shaft 4 or the conveying shaft 5 and the heat-conducting sleeve 31. The heat-conducting sleeve 31 is arranged around the axis of the through hole 100 and is fixedly and sealed to the cylinder plate 10. The heat-conducting sleeve 31 is provided with a cooling part for connecting to a cold source. The cooling part is arranged around the axis of the heat-conducting sleeve 31 and is located on the outer circumferential side of the sealing sleeve 30 to transfer cold energy to the sealing sleeve 30.

[0043] It should be noted that the cylinder body 1 is provided with an inlet for butyl rubber to enter and an outlet for butyl rubber to leave. Of course, the inlet is generally the opening of the cylinder cover on the cylinder body, thus providing a structural basis for the butyl rubber to be put into the cylinder body 1. The sealing connection between the heat-conducting sleeve 31 and the cylinder plate 10 is either seamlessly cast into one piece or sealed and welded to the cylinder plate 10, so as to ensure the sealing and fixing effect of the heat-conducting sleeve 31 and the cylinder plate 10 under the heat.

[0044] In the operation of this embodiment, when it is necessary to stir the butyl rubber, the user puts the butyl rubber to be stirred into the cylinder 1, since the stirring shaft 4 and the conveying shaft 5 are already installed inside the cylinder 1; then, the user starts the heating component 2 to heat the peripheral wall and cylinder plate 10 of the cylinder 1, so that the inside of the cylinder 1 forms a uniform high temperature environment that meets the requirements for stirring the butyl rubber; at the same time, the cold source is started, and the cold source transfers the cold energy to the cooling part, which can transfer the cold energy to the sealing sleeve 30; finally, the user starts the stirring shaft 4 and the conveying shaft 5 to stir the butyl rubber.

[0045] As can be seen from the above working process, the cooling part of the heat-conducting sleeve 31 provides continuous cooling to the sealing sleeve 30, keeping the sealing material of the sealing sleeve 30 within a stable temperature range, thereby avoiding creep and aging of the sealing material due to prolonged high temperature, and effectively sealing the stirring shaft 4 and the cylinder plate 10 as well as the conveying shaft 5 and the cylinder plate 10; and the heating component 2 can heat the cylinder plate 10 and the peripheral wall of the cylinder body 1 to form a uniform high temperature environment inside the cylinder body 1, effectively balancing the heating of the cylinder plate 10 and the sealing of the cylinder plate 10.

[0046] Compared with the prior art, the advantage of this embodiment is that the heating component 2 can heat the cylinder plate 10 and the peripheral wall of the cylinder body 1 to form a uniform high temperature environment in the cylinder body 1, so that the butyl rubber can be heated evenly. Furthermore, the heating of the cylinder plate 10 does not affect the sealing between the stirring shaft 4 and the conveying shaft 5 and the cylinder plate 10, so that the butyl rubber is heated evenly in a well-sealed kneading cylinder.

[0047] In one specific embodiment, such as Figure 4 and Figure 5 As shown, a feasible structure for the cooling section is further provided. The cooling section is a liquid-containing cavity 32, which is located inside the sleeve wall of the heat-conducting sleeve 31. The outer wall of the heat-conducting sleeve 31 is provided with an inlet 320 and an outlet 321 that communicate with the liquid-containing cavity 32. The inlet 320 and the outlet 321 are used to connect to an external liquid cooling circulation mechanism, which is the cold source. In specific implementation, after the liquid cooling circulation mechanism is connected to the inlet 320 and the outlet 321, the coolant of the liquid cooling circulation mechanism enters the inlet 320. After the coolant flows into the liquid-containing cavity 32, the cooling capacity of the coolant is transferred to the sealing sleeve 30. Finally, the coolant flows out from the outlet 321, realizing uninterrupted cold liquid circulation on the outside of the sealing sleeve 30, so that the temperature of the sealing sleeve 30 is in a stable range and the sealing material of the sealing sleeve 30 is kept stable.

[0048] In one embodiment, such as Figure 5 As shown, there are multiple inlet ports 320 and outlet ports 321; the liquid-containing chamber 32 includes multiple separate chambers 322, which are not interconnected. The multiple separate chambers 322 are arranged around the axis of the heat-conducting sleeve 31. Each separate chamber 322 is connected to an inlet port 320 and an outlet port 321. In specific implementation, the water in each separate chamber 322 flows independently, and each separate chamber 322 transfers heat to a certain area of ​​the sealing sleeve 30, resulting in better cooling effect.

[0049] In this embodiment, there can be two separate cavities 322. The two separate cavities 322 are arranged in a semi-arc shape. The annular liquid-containing cavity 32 formed by the two separate cavities 322 is arranged coaxially with the heat-conducting sleeve 31. Of course, the number of separate cavities 322 can be three, four, or five. As long as it is within the allowable number for processing, those skilled in the art can make the selection.

[0050] In another specific embodiment, another feasible structure for the cooling section is provided. The cooling section is an annular cooling pipe, which is wrapped around the outer peripheral wall of the heat-conducting sleeve 31. The annular cooling pipe is used to connect to an external water circulation mechanism. In a specific implementation, after the liquid cooling circulation mechanism is connected to the annular cooling pipe, the liquid cooling circulation mechanism circulates the coolant into the annular cooling pipe. The annular cooling pipe can transfer the cooling capacity to the sealing sleeve 30 to maintain the stability of the sealing material of the sealing sleeve 30.

[0051] In one embodiment, a feasible structure for the sealing sleeve 30 is further provided, wherein the sealing sleeve 30 is a polytetrafluoroethylene (PTFE) packing, and the PTFE packing is pressed and sealed on the outer peripheral wall of the heat-conducting sleeve 31.

[0052] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, in order to reduce the impact of the heat inside the cylinder 1 on the sealing component 3, the sealing component 3 is set on the outside of the cylinder plate 10. In specific implementation, this facilitates the subsequent replacement and maintenance of the sealing component and reduces the possibility of the material inside the cylinder being contaminated by the outside. The stirring paddle will sweep across the entire cylinder and cylinder plate, and the gap between it and the cylinder 1 and cylinder plate 10 is small. If the sealing component 3 is set inside the cylinder plate, it will interfere with the stirring paddle.

[0053] In one specific embodiment, such as Figures 1 to 3 As shown, a feasible structure for the heating assembly 2 is further provided. The heating assembly 2 includes a first heating part 20 and a second heating part 21. The first heating part 20 is disposed on the wall of the cylinder plate 10 and is used to heat the cylinder plate 10. The second heating part 21 is disposed on the peripheral side wall of the cylinder body 1 and is used to heat the peripheral side wall of the cylinder plate 10. The first heating part 20 and the second heating part 21 can adaptively adjust various heating temperatures according to the internal temperature of the cylinder body 1 to form a uniform high-temperature environment suitable for butyl rubber inside the cylinder body 1. In specific implementation, the first heating part 20 heats the cylinder plate 10, and the second heating part 21 heats the outer peripheral side of the cylinder body 1. The first heating part 20 and the second heating part 21 work together to heat all the walls of the cylinder body 1, thereby forming a uniform high-temperature environment suitable for butyl rubber inside the cylinder body 1.

[0054] In one embodiment, such as Figure 1 and Figure 2As shown, a feasible structure for the first heating section 20 is further provided. The first heating section 20 includes multiple baffle-type heating elements 200, which are arranged side by side on the outer wall of the cylinder plate 10 to cover the outer wall of the cylinder plate 10. That is, the multiple baffle-type heating elements 200 heat a certain area of ​​the cylinder plate 10 respectively, realizing zoned heating. The heating temperature can be independently adjusted according to the situation of each area to ensure uniform internal temperature of the cylinder 1. In specific implementation, the coolant in the baffle-type heating elements 200 will form multiple Z-shaped flow paths under the guidance of the internal baffle structure, prolonging the heating time and enhancing the turbulence effect, thereby improving the heat exchange efficiency and effectively heating the cylinder plate 10.

[0055] In one embodiment, such as Figure 3 As shown, the second heating part 21 includes multiple heating jackets 210, which are all sleeved on the outer peripheral sidewall of the cylinder body 1. Along the axial direction of the cylinder body 1, the multiple heating jackets 210 are arranged coaxially to cover the outer peripheral sidewall of the cylinder body 1. That is, the multiple heating jackets 210 heat a certain area of ​​the peripheral sidewall of the cylinder body 1 respectively. The principle is the same as that of the first heating part 20, which can realize zoned heating. In specific implementation, the multiple heating jackets 210 are arranged in a ring shape so that the peripheral sidewalls of different areas of the cylinder body 1 can be heated.

[0056] In one embodiment, in order to improve the heating effect of the heating component 2, the outer wall of the heating component 2 is covered with a heat insulation layer. That is, the outer walls of the multiple baffle heating elements 200 and the outer walls of the multiple heating jackets 210 are all provided with heat insulation layers. The heat insulation layer can be heat insulation cotton. The heat insulation layer can reduce the heat impact of the heating component 2 on external components on the one hand, and maintain the heating effect of the heating component 2 on the cylinder 1 on the other hand.

[0057] In one specific embodiment, such as Figures 1 to 3 As shown, a structural reinforcing plate 11 is fixed inside the cylinder body 1. The structural reinforcing plate 11 is connected and fixed to the two cylinder plates 10. The length direction of the structural reinforcing plate 11 is arranged along the axial direction of the cylinder body 1, dividing the cylinder body 1 into two interconnected spaces. The arrangement of the structural reinforcing plate 11 can enhance the structural strength of the cylinder body 1. Furthermore, the structural reinforcing plate 11 can also be connected to a structural reinforcing side plate 12. The structural reinforcing side plate 12 is connected to the peripheral side wall of the cylinder body 1 to enhance the circumferential load-bearing capacity of the cylinder body 1.

[0058] Please refer to Figure 6 and Figure 7 The second aspect of this utility model provides a butyl rubber type kneader, comprising:

[0059] The first aspect is the kneading cylinder a;

[0060] The stirring mechanism b is provided with a stirring shaft 4 and a conveying shaft 5. The stirring shaft 4 and the conveying shaft 5 are respectively inserted into the kneading cylinder a through the through hole 100.

[0061] The reduction mechanism c has a reduction output shaft that is connected to shaft 4 and conveyor shaft 5.

[0062] The drive mechanism d has its drive output shaft connected to the reduction input shaft of the reduction mechanism c.

[0063] In the operation of this embodiment, the drive mechanism d is started, and the speed of the stirring shaft 4 and the conveying shaft 5 of the stirring mechanism b is adjusted by the deceleration mechanism c so that the stirring shaft 4 and the conveying shaft 5 can rotate at a suitable speed.

[0064] In one specific embodiment, the kneading cylinder a has three through holes 100. The stirring mechanism b includes two paddle shafts b1 for connecting the stirring blades and a screw shaft b2 for connecting the screw. The two paddle shafts b1 and the screw shaft b2 are respectively inserted into the kneading cylinder a through the three through holes 100. The reduction mechanism c is an integrated reduction gearbox with a circulating oil pump. The integrated reduction gearbox can be a KONE model TLSJS1050620-00-WX reduction gearbox. The two paddle shafts b1 and the screw shaft b2 are respectively connected to the three reduction output shafts of the integrated reduction gearbox through a gear hub coupling f. The drive mechanism d includes two paddle shaft motors d1 and one screw motor d2. The lever motor d2 is connected to the three reduction input shafts of the integrated gearbox via three swivel couplings e. All three swivel couplings e and three gear hub couplings f are equipped with protective covers. In practice, the two propeller shafts b1 and the screw shaft b2 can be independently controlled by the two propeller motors d1 and the screw motor d2, respectively. Because they share a single gearbox and are lubricated by a circulating oil pump, and the three independent drive motors are connected by couplings, the speeds of the two propeller shafts b1 and the screw can be controlled independently. The entire transmission mechanism is very neat and compact, simplifying installation and subsequent maintenance, eliminating the need for at least two reducers to control the rotation of the two propeller shafts b1 and the screw, as is required in existing technologies. Some manufacturers use three reducers to independently control the speed of the two propeller shafts b1, making the kneader's transmission mechanism very large and complex, which is detrimental to equipment layout.
