Description

Technical Field

[0001] The invention relates to the technical field of rubber, in particular to a horizontal vulcanizing tank used for rubber production. Background Art

[0002] The vulcanization tank is a commonly used equipment in the production of rubber products. It is mainly used in the vulcanization process of rubber products. By providing a certain temperature, pressure and time, the rubber molecules undergo cross-linking reactions, thereby improving the physical and chemical properties of the rubber, such as strength, elasticity, and wear resistance. Among them, the steam vulcanization tank uses steam as a heating medium to achieve the vulcanization process. The steam contains impurities, such as scale and rust. During long-term use, these impurities will enter the diffusion tube with the steam and deposit at the vents. After the vulcanization is completed, some debris will be generated when the rubber products are replaced. These debris will fall on the surface of the steam diffusion tube and accumulate at the vents, resulting in venting. The holes are clogged. If the air holes are clogged and not cleaned in time, the uniform diffusion of steam will be affected. The steam cannot enter various areas inside the vulcanizer through the air holes normally, resulting in uneven temperature and pressure distribution at different positions in the tank, which leads to inconsistent vulcanization degree of rubber products. When steam is ejected outward from the air holes of the diffusion tube in a single direction, the steam is mainly concentrated in the area along the axis of the air holes. There will be more steam in the area close to the axis of the air holes, and less steam in the area far from the axis, which leads to uneven steam diffusion. At the same time, the high-speed jetted steam directly impacts the rubber product, which may cause local physical damage to the surface of the rubber. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, and this embodiment provides a horizontal vulcanization tank for rubber production. The horizontal vulcanization tank for rubber production includes a main body component 100, including a vulcanization tank 101 and a steam diffusion pipe 102. The steam diffusion pipe 102 is fixed in the vulcanization tank 101, and a vent hole 102-1 is opened on the steam diffusion pipe 102.

[0032] The vulcanization tank 101 is used to store rubber that needs to be vulcanized. An external pipe is provided at the bottom of the vulcanization tank 101. Steam is transported to the steam diffusion pipe 102 through the external pipe and sprayed out through the air vent 102-1. In this way, the interior of the vulcanization tank 101 can be pressurized and heated, and the rubber can be vulcanized. This is a prior art and will not be elaborated in detail in this solution. Those skilled in the art can clearly understand the working principle.

[0033] There are a plurality of air holes 102 - 1 , which are evenly distributed on the steam diffusion pipe 102 along a predetermined trajectory.

[0034] Specifically, the auxiliary component 200 is arranged on the steam diffusion tube 102, including a dredging rod 201, the dredging rod 201 is located above the steam diffusion tube 102 and is coaxial with the air vent 102-1, a rotating sleeve 202 is sleeved on the outer side of the dredging rod 201, a blade 203 is fixed on the outer side of the rotating sleeve 202, a diffusion plate 211 is fixed on the top of the rotating sleeve 202, a mounting block 204 is rotatably connected to the outer side of the end of the dredging rod 201, and a spring 205 is sleeved on the outer side of the dredging rod 201. The two ends of the spring 205 are respectively fixed to the mounting block 204 and the rotating sleeve 202. A spiral groove 201-1 is provided on the dredging rod 201. A fixed shaft 206 is fixed in the rotating sleeve 202. The fixed shaft 206 cooperates with the spiral groove 201-1. An annular groove 201-2 is provided on the dredging rod 201. The fixed shaft 206 slides in the annular groove 201-2. A protective cover 212 is provided on the outer side of the blade 203. The protective cover 212 is fixed to the rotating sleeve 202 through a connecting rod.

[0035] The number of the auxiliary components 200 corresponds to the air holes 102 - 1 , and the diameter of the dredging rod 201 is slightly smaller than the diameter of the air holes 102 - 1 .

[0036] The steam ejected outward from the air hole 102-1 will first be sprayed on the blade 203, and the blowing force of the steam will drive the blade 203 to rotate, and the rotating sleeve 202 and the diffusion disk 211 will be driven to rotate through the blade 203. When the diffusion disk 211 rotates, the ejected steam can be dispersed to the surroundings in a ring manner, so that the steam can be effectively dispersed to a larger range. Moreover, through rotation, the dispersion direction of the steam is no longer limited to the axial direction of the air hole 102-1, but can be diffused in the circumferential direction and within a certain angle range, so that the steam is distributed more evenly in the vulcanization tank 101, and the steam is prevented from being sprayed directly on the rubber when ejected, and the impact force of the steam can be buffered, thereby avoiding local physical damage to the surface of the rubber.

[0037] When the air hole 102-1 is blocked and cannot eject steam, the blade 203 stops rotating due to the loss of the thrust of the steam. At this time, the spring 205 applies a pulling force to the mounting block 204 and drives the unblocking rod 201 to move toward the inside of the air hole 102-1. The air hole 102-1 can then be unblocked by the unblocking rod 201 to prevent steam from being unable to normally pass through the air hole 102-1 into various areas inside the vulcanization tank, resulting in uneven temperature and pressure distribution at different positions in the tank, which results in inconsistent vulcanization degree of the rubber product.

[0038] When the air hole 102-1 is unblocked and the air hole 102-1 can normally spray steam outward, the blade 203 will rotate again and drive the rotating sleeve 202 to rotate. The rotating sleeve 202 will also drive the fixed shaft 206 to slide in the spiral groove 201-1. The cooperation of the two drives the dredging rod 201 to move, so that the dredging rod 201 is separated from the air hole 102-1, so as to avoid the dredging rod 201 from being continuously inside the air hole 102-1, which will affect the situation where the air hole 102-1 sprays steam outward. After the dredging rod 201 moves a certain stroke, the fixed shaft 206 will enter the annular groove 201-2, and the dredging rod 201 will stop moving. With the continuous rotation of the rotating sleeve 202, the dredging rod 201 will always stay in this position and will not enter the air hole 102-1.

[0039] When the vulcanization is completed and the rubber needs to be replaced, the air hole 102-1 stops spraying steam outward, and the clearing rod 201 is inserted into the air hole 102-1 to cover the air hole 102-1 to prevent impurities from falling on the air hole 102-1 and causing the air hole 102-1 to be blocked during the rubber replacement process.

[0040] Since the diameter of the dredging rod 201 is smaller than the diameter of the air hole 102-1, when the dredging rod 201 is inserted into the air hole 102-1, it will only reduce the steam sprayed out of the air hole 102-1, and will not cause the air hole 102-1 to be unable to spray steam outward. Therefore, when the dredging rod 201 is inserted into the air hole 102-1, the steam sprayed out of the air hole 102-1 will still drive the blade 203 to rotate, as long as the air hole 102-1 is in a normal dredging state.

[0041] Example 2

[0042] Reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, a support sleeve 207 is sleeved on the outer side of the rotating sleeve 202, a positioning ring 208 is fixed inside the support sleeve 207, a positioning groove 202-1 is opened on the rotating sleeve 202, and the positioning ring 208 is movably connected with the positioning groove 202-1.

[0044] The rotating sleeve 202 rotates with the supporting sleeve 207 through the cooperation between the positioning ring 208 and the positioning groove 202 - 1 . The supporting sleeve 207 is used to support and position the rotating sleeve 202 .

[0045] Specifically, a support column 209 is fixed to one side of the support sleeve 207 , and the bottom end of the support column 209 is fixed to the steam diffusion pipe 102 for supporting the support sleeve 207 .

[0046] The support column 209 is L-shaped and is used to support and fix the support sleeve 207 .

[0047] Specifically, a limiting block 210 is fixed in the support sleeve 207, a limiting groove 201-3 is provided on the dredging rod 201, and the limiting block 210 is movably connected to the limiting groove 201-3.

[0048] The cooperation between the limiting block 210 and the limiting groove 201 - 3 is used to limit the dredging rod 201 to prevent the dredging rod 201 from rotating when moving.

[0049] Specifically, there are multiple spiral grooves 201 - 1 , which are evenly distributed in a ring shape on the outside of the dredging rod 201 , and the multiple spiral grooves 201 - 1 are all connected to the annular groove 201 - 2 .

[0050] By providing a plurality of spiral grooves 201 - 1 , when the rotating sleeve 202 stops rotating, the fixed shaft 206 can enter the spiral groove 201 - 1 at any position inside the annular groove 201 - 2 .

[0051] Specifically, there are multiple blades 203 , which are fixed to the outside of the rotating sleeve 202 in a ring shape. The multiple blades 203 are all inclined. The arrangement of the multiple blades 203 ensures the stability of the rotation of the rotating sleeve 202 .

[0052] Example 3

[0053] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0054] Specifically, the bottom end of the dredging rod 201 is conical, and the diffusion plate 211 is conical.

[0055] By setting the bottom end of the dredging rod 201 to a cone, the obstruction of steam spraying outward can be reduced. By setting the diffusion plate 211 to a cone, the steam can be diffused upward when it rotates, thereby accelerating the speed of steam diffusion.

[0056] Specifically, a sealing cover 103 is disposed on one side of the vulcanizing tank 101 , a fixing frame 104 is disposed on one side of the sealing cover 103 , and a hand wheel 105 is disposed on the fixing frame 104 .

[0057] The sealing cover 103 is used to seal the interior of the vulcanizing tank 101. The sealing cover 103 and the vulcanizing tank 101 can be locked by rotating the hand wheel 105. This is the prior art.

[0058] Specifically, a track 106 is fixed inside the vulcanization tank 101 , and there are two tracks 106 , which are respectively located at two ends of the steam diffusion pipe 102 .

[0059] The track 106 is used to support the rack on which the rubber is placed and facilitate the movement of the rack.

[0060] Specifically, a controller 107 is provided on one side of the vulcanization tank 101 .

[0061] The controller 107 is used to control the pressure and temperature inside the vulcanization tank 101, which is a prior art.

[0062] When in use, the rack for placing rubber is pushed into the vulcanization tank 101, and then the sealing cover 103 is closed and locked. At this time, the steam can be transported into the steam diffusion pipe 102 and sprayed out through the air vent 102-1, so that the inside of the vulcanization tank 101 can be pressurized and heated, and then the rubber can be vulcanized.

[0063] The steam ejected outward from the air hole 102-1 will first be sprayed on the blade 203. At this time, the blowing force of the steam drives the blade 203 to rotate, and the rotating sleeve 202 and the diffusion disk 211 are driven to rotate through the blade 203. When the diffusion disk 211 rotates, the ejected steam can be dispersed to the surroundings in a ring manner, so that the steam can be effectively dispersed to a larger range. Moreover, through rotation, the dispersion direction of the steam is no longer limited to the axial direction of the air hole 102-1, but can be diffused in the circumferential direction and within a certain angle range, so that the steam is distributed more evenly in the vulcanization tank 101, and the steam is prevented from being sprayed directly on the rubber when ejected, and the impact force of the steam can be buffered, thereby avoiding local physical damage to the surface of the rubber.

[0064] When the air hole 102-1 is blocked and cannot eject steam, the blade 203 stops rotating due to the loss of the thrust of the steam. At this time, the spring 205 applies a pulling force to the mounting block 204 and drives the unblocking rod 201 to move toward the inside of the air hole 102-1. The air hole 102-1 can then be unblocked by the unblocking rod 201 to prevent steam from being unable to normally pass through the air hole 102-1 into various areas inside the vulcanization tank, resulting in uneven temperature and pressure distribution at different positions in the tank, which results in inconsistent vulcanization degree of the rubber product.

[0065] When the air hole 102-1 is unblocked and the air hole 102-1 can normally spray steam outward, the blade 203 will rotate again and drive the rotating sleeve 202 to rotate. The rotating sleeve 202 will also drive the fixed shaft 206 to slide in the spiral groove 201-1. The cooperation of the two drives the dredging rod 201 to move, so that the dredging rod 201 is separated from the air hole 102-1, so as to avoid the dredging rod 201 from being continuously inside the air hole 102-1, which will affect the situation where the air hole 102-1 sprays steam outward. After the dredging rod 201 moves a certain stroke, the fixed shaft 206 will enter the annular groove 201-2, and the dredging rod 201 will stop moving. With the continuous rotation of the rotating sleeve 202, the dredging rod 201 will always stay in this position and will not enter the air hole 102-1.

[0066] When the vulcanization is completed and the rubber needs to be replaced, the air hole 102-1 stops spraying steam outward, and the clearing rod 201 is inserted into the air hole 102-1 to cover the air hole 102-1 to prevent impurities from falling on the air hole 102-1 and causing the air hole 102-1 to be blocked during the rubber replacement process.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
