Description

Technical Field

[0001] The invention belongs to the technical field of degassing machines, and in particular relates to a rapid heat dissipation degassing cylinder. Background Art

[0002] A deaerator is a device used to remove bubbles from materials. The main types of deaerators include vacuum deaerators, centrifugal deaerators, and pressure deaerators. Centrifugal deaerators consist of a centrifuge and a deaerator drum containing the material. They lack complex vacuum or pressure control systems, resulting in a simple structure and low cost, making them suitable for online deaeration in large-scale production. Compared to other types of deaerators, they are simple to operate and offer higher production efficiency. However, centrifugal deaerators often suffer from material heating. During the deaeration process, the material's temperature rises due to high-speed centrifugal motion. To address this issue, existing treatment methods are as follows: 1. Reduce the speed: Centrifugal force is proportional to the square of the speed. Excessive speed is one of the main reasons for material heating. Reducing the speed can reduce the internal friction and collision heat generated by the centrifugal force.

[0003] 2. Shorten the centrifugal time: Reducing the time the material is in the centrifugal field can effectively reduce the heat generation.

[0004] 3. Add heat dissipation additives: Add heat dissipation additives to the material that needs to be degassed, such as thermal conductive fillers (such as alumina, boron nitride, etc.), to improve the thermal conductivity of the material, so that the heat can be conducted out more quickly, thereby reducing the temperature inside the material.

[0005] However, methods 1 and 2 above reduce the efficiency of a single degassing operation, significantly impacting the efficiency of large-scale degassing operations and failing to fully utilize the high-efficiency advantages of centrifugal degassing machines. Method 3 is only suitable for materials that require a heat dissipation agent, which is a limited variety and restricts its application. Therefore, a degassing cartridge with a built-in heat dissipation function is needed to address these issues. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the present invention provides a rapid heat dissipation and degassing cylinder, comprising a cylinder with an open upper end, the outer surface of the side wall of the cylinder is provided with spiral blades, and the interior of the cylinder is provided with a turbulent heat conductor; the turbulent heat conductor comprises a central tube and a spoiler, and the central tube is longitudinally connected to the center of the cylinder; the spoiler is provided with a plurality of pieces, one side of each spoiler is fixedly connected to the central tube, and the other side is radially close to the inner surface of the cylinder, and all the spoilers are distributed along the circumferential direction; the side of each spoiler is distributed with flow holes, and the interior of the spoiler is provided with a cooling channel; the two ends of the cooling channel of each spoiler are respectively connected to the liquid inlet channel and the liquid inlet channel of the central tube. The liquid return channels are connected one by one; the inner surface of the cylinder is provided with a longitudinal limit piece connected to each spoiler, which is engaged in the longitudinal groove of the longitudinal limit piece through the side of the spoiler, thereby limiting the rotation of the spoiler around the center tube; the cylinder is provided with locking holes corresponding one by one to all the longitudinal limit pieces, and the upper end of each longitudinal limit piece is provided with a locking groove opposite to the corresponding locking hole; the spoiler heat conductor is locked in the cylinder by a locking mechanism, the middle part of the locking mechanism is sleeved on the center tube, and the locking mechanism is provided with an elastic locking rod opposite to all the locking holes, each elastic locking rod radially penetrates the locking groove and is inserted into the corresponding locking hole, thereby locking the longitudinal limit piece to the cylinder.

[0007] The preferred embodiment of the rapid heat dissipation and degassing cylinder of the present invention comprises: a central stopper surrounding the central tube is provided on the bottom wall of the cylinder, with a notch corresponding to each spoiler; the bottom wall of the cylinder is also provided with edge stops on either side of each longitudinal stopper. The lower ends of all spoilers are captured by the central and edge stops, preventing the spoilers, central tube, and cylinder from moving relative to each other. During centrifugation, the spoilers do not move with the material, maintaining an effective disturbance effect on the material.

[0008] The preferred solution of the rapid heat dissipation and degassing cylinder in the present invention is as follows: each elastic locking rod includes an L-shaped rod, a spring and a guide column; one end of each guide column is fixedly connected to the middle part of the locking mechanism, and the other end of the guide column is movably connected to one end of the L-shaped rod, and the spring is sleeved on the guide column; the other end of each L-shaped rod extends along the length direction of the upper end of the corresponding spoiler and is inserted into the corresponding locking groove and locking hole; each adjacent two L-shaped rods are connected by two staggered pull ropes. The upper end of each longitudinal limiter is provided with a step surface flush with the upper end surface of the corresponding spoiler, and the bottom of each L-shaped rod is just placed on the step surface of the upper end surface of the corresponding spoiler and the longitudinal limiter, and the end of the L-shaped rod is provided with a step surface corresponding to the step of the upper end of the longitudinal limiter. When the L-shaped rod is locked in the locking hole, the L-shaped rod, the longitudinal limiter and the spoiler are tightly combined and locked, and no shaking problem occurs during centrifugal movement.

[0009] The preferred embodiment of the rapid heat dissipation and degassing cylinder of the present invention is as follows: the aperture of each flow hole gradually increases from one end to the other, and the direction of the aperture increase is consistent with the direction of the centrifugal motion of the cylinder; the flow holes of each spoiler are arranged in a rectangular array. Furthermore, a cooling channel is distributed on the upper and lower sides of each row of flow holes of each spoiler. During centrifugal motion, the material flows within the cylinder, passing through the structure of flow holes with one end larger and the other smaller, increasing the flow rate, improving the disturbance effect of the spoiler relative to the material, increasing the thermal conductivity, and reducing the temperature within the material.

[0010] The preferred embodiment of the rapid heat dissipation degassing cylinder of the present invention is as follows: the spiral blades are provided in multiple pieces, all of which are evenly distributed along the circumference of the cylinder. The spiral blades distributed on the outer surface of the cylinder can accelerate air flow during centrifugal motion, accelerating the removal of heat from the cylinder, thereby improving the heat dissipation effect of the cylinder.

[0011] The preferred solution of the rapid heat dissipation and degassing cylinder of the present invention is that a heat conductive agent is filled between the longitudinal groove and the side of the spoiler.

[0012] The beneficial effects of the rapid heat dissipation and degassing cylinder of the present invention are: 1. Before degassing, secure the turbulent heat conductor to the cylinder. Then, load the material into the cylinder and place it in the centrifuge for centrifugal motion. This transfers some of the material's heat to the cylinder, which is then transferred to the air by the spiral blades, lowering the material's surface temperature. The remaining heat is transferred to the turbulent plate, which then transfers it to the coolant flowing in the cooling channel, lowering the material's internal temperature. Both external and internal heat are quickly dissipated, reducing the material's temperature. This reduces the likelihood of material degradation due to high temperatures and helps maintain its performance.

[0013] 2. Compared with existing heat treatment methods, there is no need to reduce the centrifugal speed and time, maintaining the original high efficiency of the centrifugal degassing machine. In addition, there is no need to add heat dissipation materials to the material, and there is no impact on the purity of the material. It can be applied to most degassing materials and has almost unlimited use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In view of the deficiencies in the prior art, the inventors of this case have proposed the technical solution of the present invention after long-term research and extensive practice. The following will further explain the technical solution, its implementation process and principles, etc. in conjunction with the drawings in the embodiments of this application and specific implementation cases.

[0020] like Figure 1 As shown, this embodiment provides a rapid heat dissipation and degassing cylinder, comprising a cylinder 1 with an opening at the upper end, and spiral blades 101 are provided on the outer surface of the side wall of the cylinder 1. The spiral blades 101 are provided in multiple pieces, and the number of spiral blades 101 is determined according to the volume of the cylinder 1. The larger the volume of the cylinder 1, the more spiral blades 101 there are. All the spiral blades 101 are evenly distributed along the circumference of the cylinder 1. The spiral blades 101 distributed on the outer surface of the cylinder 1 can accelerate the flow of air during the centrifugal motion, and the heat of the surface material of the part in contact with the cylinder 1 can be quickly transferred to the surrounding air, thereby reducing the surface temperature of the material.

[0021] In order to solve the problem of high temperature inside the material, this embodiment provides a turbulent heat conductor 2 inside the cylinder 1. The specific structure of the turbulent heat conductor 2 is as follows: like Figure 3 and Figure 4As shown, the spoiler heat conductor 2 includes a central tube 201 and a spoiler 202. The spoiler 202 and the cylinder 1 are made of a metal material, such as stainless steel, which does not react with stainless steel. Other materials may also be used, and this is not limited to this embodiment. The central tube 201 is longitudinally connected to the center of the cylinder 1, and the bottom wall of the cylinder 1 is provided with a central stopper 103 surrounding the central tube 201. There are six spoilers 202, and one side of each spoiler 202 is fixedly connected to the central tube 201. The central stopper 103 is provided with a notch corresponding to each spoiler 202. The central stopper 103 has six notches, each of which holds a spoiler 202. The other side of each spoiler 202 is radially close to the inner surface of the cylinder 1, and all the spoilers 202 are distributed circumferentially, that is, the six spoilers 202 are distributed in a divergent manner from the central tube 201 to the surrounding area. To further secure the spoilers 202, longitudinal stoppers 104 connected to each spoiler 202 are provided on the inner surface of the cylinder 1. The side edges of the spoilers 202 engage with longitudinal grooves 105 of the longitudinal stoppers 104, thereby restricting the rotation of the spoilers 202 around the central tube 201. To enhance heat conduction, a thermal conductive agent 106 is filled between the longitudinal grooves 105 and the side edges of the spoilers 202 to accelerate heat conduction between the spoilers 202 and the cylinder 1.

[0022] The longitudinal limiter 104 is locked using the following structure: like Figure 4 and Figure 5 As shown, the bottom wall of the cylinder 1 is also provided with edge limit blocks 107 clamped on both sides of each longitudinal limit member 104, and the lower part of the edge limit block 107 is fixed by the edge limit block 107, and the ear plate 108 at the upper end of the cylinder 1 is provided with locking holes 109 corresponding to all the longitudinal limit members 104 one by one, and the upper end of each longitudinal limit member 104 is provided with a locking groove 102 facing the corresponding locking hole 109, and the locking groove 102 is flush with the locking hole 109.

[0023] like Figure 1 and Figure 2As shown, this embodiment also includes a locking mechanism 3, with a central hole provided in the middle of the locking mechanism 3, through which the central portion of the locking mechanism 3 is sleeved on the central tube 201. The locking mechanism 3 is provided with elastic locking rods 301 corresponding to all locking holes 109. Each elastic locking rod 301 radially penetrates the locking groove 102 and is inserted into the corresponding locking hole 109, thereby locking the longitudinal limit member 104 with the cylinder body 1. Specifically, each elastic locking rod 301 includes an L-shaped rod 302, a spring 303, and a guide post 304; one end of each guide post 304 is fixedly connected to the central portion of the locking mechanism 3, and the other end of the guide post 304 is movably connected to one end of the L-shaped rod 302, and the spring 303 is sleeved on the guide post 304. The other end of each L-shaped rod 302 extends along the length of the upper end of the corresponding spoiler 202 and is inserted into the corresponding locking groove 102 and locking hole 109. Two adjacent L-shaped rods 302 are connected by two interlaced drawstrings 305. The upper end of each longitudinal stopper 104 is provided with a stepped surface 306 that is flush with the upper end surface of the corresponding spoiler 202. The lower end of each L-shaped rod 302 rests on the upper end surface of the corresponding spoiler 202 and the stepped surface 306 of the longitudinal stopper 104. The distal end of the L-shaped rod 302 is provided with a stepped surface 306 that corresponds to the stepped portion of the longitudinal stopper 104. When the L-shaped rod 302 is locked in the locking hole 109, the L-shaped rod 302, the longitudinal stopper 104, and the spoiler 202 are tightly coupled and locked, preventing any shaking during centrifugal motion.

[0024] The locking mechanism 3 is used as follows: first, place the central tube 201, longitudinal stopper 104, and all spoilers 202 into the cylinder 1. Each spoiler 202 engages with its corresponding central stopper 103, and each longitudinal stopper 104 engages with its corresponding edge stopper 107. The locking mechanism 3 is then installed by pulling at least two opposing L-shaped rods 302 toward the center. The remaining L-shaped rods 302 are then driven synchronously toward the center by adjacent pull cords 305. All L-shaped rods 302 slide along their corresponding guide posts 304, compressing the springs 303. The L-shaped rod 302 is retracted to a certain distance toward the middle, and then the middle part of the locking mechanism 3 is sleeved on the upper end of the central tube 201. The ends of the six L-shaped rods 302 of the locking mechanism 3 are placed in the corresponding locking grooves 102 respectively, and then the L-shaped rods 302 are loosened. All the L-shaped rods 302 are inserted into the locking holes 109 along the locking grooves 102 under the elastic force of the springs 303, thereby locking the turbulent heat conductor 2 in the cylinder 1. If it is necessary to remove the turbulent heat conductor 2, at least two relative L-shaped rods 302 are pulled toward the middle, and the remaining L-shaped rods 302 are driven by the adjacent pull ropes 305 to move synchronously toward the middle, so that all the L-shaped rods 302 exit the locking holes 109. The installation and disassembly operations of the locking mechanism 3 are convenient and fast. After the turbulent heat conductor 2 is locked by the locking mechanism 3, the degassing operation of the same type of material does not need to repeatedly disassemble and assemble the turbulent heat conductor 2, which does not affect the efficiency of the batch degassing operation.

[0025] As shown Figure 3 and 5As shown, on the side of each spoiler 202, there are holes for circulation 203, and inside the spoiler 202, there is a cooling channel 204. The two ends of the cooling channel 204 of each spoiler 202 are respectively connected to the liquid inlet channel 205 and the liquid return channel 206 of the central tube 201. The upper end of the central tube 201 is provided with a double-layer pipe joint 207 connected to the liquid inlet channel 205 and the liquid return channel 206. The double-layer pipe joint 207 is connected to the external cooling pipe. A rotary joint needs to be set between the external cooling pipe and the double-layer pipe joint 207. During the centrifugal movement of the rapid heat dissipation degassing cylinder driven by the centrifuge, the rotary joint is kept connected to the double-layer pipe joint 207, while not affecting the centrifugal movement of the rapid heat dissipation degassing cylinder. The external cooling pipe and the rotary joint are not drawn in the figure. In order to improve the internal heat dissipation effect of the material, the aperture of each hole for circulation 203 gradually increases from one end to the other, and the direction of the aperture increase is consistent with the direction of the centrifugal movement of the cylinder 1. During centrifugal motion, the material flows within the cylinder 1, passing through the structure of the flow holes 203, which are larger at one end and smaller at the other. This increases the flow rate, enhances the disturbance effect of the spoiler 202 on the material, improves the heat conduction effect, and reduces the temperature within the material. Furthermore, the flow holes 203 of each spoiler 202 are arranged in a rectangular array, with a cooling channel 204 distributed above and below each row of flow holes 203 of each spoiler 202. For example, if the flow holes 203 of each spoiler 202 are arranged in a rectangular array of five rows and four columns, the spoiler 202 is provided with five cooling channels 204, each surrounding the upper and lower sides of a row of flow holes. The material collides and rubs against the flow holes, generating a large amount of heat, which is concentrated. The heat in each row of flow holes is promptly carried away by the coolant flowing in the surrounding cooling channel 204, thus preventing localized temperature rise. The material flows relative to the cylinder 1 and transfers heat to the spoiler 202 during the flow process. The heat of the spoiler 202 is transferred to the coolant flowing in the cooling channel 204, thereby reducing the internal temperature of the material.

[0026] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make some simple deductions or substitutions without departing from the concept of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the scope of protection of the present invention.
