Description

Technical Field

[0001] The present invention belongs to the technical field of accessories for centrifugal defoaming machines, and particularly relates to a rotating heat dissipation device for a defoaming machine. Background Art

[0002] Centrifugal defoaming machines are often used for defoaming liquids with relatively high viscosities, such as inks, glues, etc. Their defoaming speed is relatively fast, and they are particularly suitable for processing large batches of materials. The specific usage method of a centrifugal defoaming machine is as follows: Load the material to be defoamed into the defoaming bucket, then symmetrically place the defoaming bucket on the centrifugal disk of the centrifugal defoaming machine. The centrifugal disk drives the defoaming bucket to rotate at a high speed. By using centrifugal force, the bubbles in the material are separated from the material under the action of the centrifugal force field, thereby achieving the purpose of defoaming. During the high-speed rotation of the material, the material itself generates heat. The centrifugal speed is proportional to the heat generation, and its internal temperature becomes higher and higher, making it impossible to balance the contradiction between high rotation speed and the heat generated by the material itself.

[0003] In response to the above problems, the existing treatment method is: Coating a heat-conducting material on the outer surface of the defoaming bucket to solve the problem of the interfacial thermal resistance between the defoaming bucket and the centrifugal disk. However, this method has the following deficiencies: 1. The price of the heat-conducting material is expensive. After each defoaming operation, the heat-conducting material attached to the outer surface of the defoaming bucket needs to be cleaned, and the heat-conducting material needs to be re-coated for the next operation. For large-batch defoaming operations, the operation steps increase, the cleaned heat-conducting material is wasted, and a certain amount of heat-conducting material needs to be consumed each time, thereby reducing the efficiency of large-batch defoaming operations and increasing the cost.

[0004] 2. In order to avoid reactions between the defoaming bucket and the material, the material of the defoaming bucket is mainly plastic, with a single structure. The strength of the plastic defoaming bucket is relatively low. Materials with relatively high viscosities cause the defoaming bucket to deform due to the "drag" of the centrifugal force, and the defoaming bucket lacks a support structure.

[0005] 3. Temperature has an impact on the material itself. For example, as the temperature rises, the material itself undergoes reactions, and the change in the properties of the material results in unqualified quality. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a rotating heat dissipation device for a defoaming machine, which includes an inner container with an open upper end and an outer shell with an open upper end, and a middle fixing ring and a lower fixing ring adapted to the barrel body of the inner container are respectively provided in the middle and lower parts inside the outer shell; the space between the middle fixing ring and the lower fixing ring is a storage cavity, a gap is provided between the lower fixing ring and the side wall of the inner container, and the storage cavity is communicated with the gap; an movable ring that can slide up and down is provided in the storage cavity, an elastic telescopic shaft is provided at the upper end of the middle fixing ring, and the lower end of the elastic telescopic shaft penetrates through the middle fixing ring and is fixedly connected to the movable ring. By pressing the inner container into the inner cavity of the outer shell and squeezing the elastic telescopic shaft, the movable ring squeezes the heat-conducting agent in the storage cavity into the gap and the space between the bottom wall of the inner container and the outer shell.

[0007] A preferred embodiment of the rotating heat dissipation device for a defoaming machine in the present invention is: a plurality of elastic telescopic shafts are provided, and all the elastic telescopic shafts are distributed along the circumferential direction; each elastic telescopic shaft includes a spring and a telescopic rod, the middle fixing ring is provided with through holes corresponding to each telescopic rod one by one, each spring is sleeved on the corresponding telescopic rod, a retaining ring fixedly connected to the upper ends of all the telescopic rods is provided above the middle fixing ring, and the lower ends of all the telescopic rods are inserted into the corresponding through holes one by one, so that all the springs are located between the retaining ring and the middle fixing ring. When the inner container presses down the telescopic rod, the spring is compressed at the same time. After the defoaming operation is completed, the inner container is withdrawn by the elastic force of the spring, effectively solving the problem that the inner container cannot be quickly taken out due to the adhesion of the heat-conducting agent, which affects the efficiency of batch defoaming operation.

[0008] A preferred embodiment of the rotating heat dissipation device for a defoaming machine in the present invention is: downwardly directed guide posts are provided on the outer side of the upper part of the inner container, and at least two guide posts are provided; guide holes corresponding to all the guide posts one by one are provided at the upper end of the outer shell. The guide posts and the guide holes can quickly align the inner container and the outer shell, improving the efficiency of batch defoaming operation.

[0009] A preferred embodiment of the rotating heat dissipation device for a defoaming machine in the present invention is: the cross section of the middle fixing ring is in the shape of a "7", the upper end of the middle fixing ring is fixedly connected to the inner surface of the outer shell, and a piston cavity is formed between the middle fixing ring and the outer shell; the movable ring is located in the piston cavity, and the two side surfaces of the movable ring are respectively in sliding seal with the side surface of the middle fixing ring and the side surface of the outer shell. The movable ring is equivalent to a piston body, and the piston ring seals and slides in the piston cavity to form a piston structure. During the process of the inner container descending, the movable ring scrapes the heat-conducting agent attached to the outer side surface of the movable ring and the inner side surface of the inner container. On the contrary, during the process of the inner container ascending, a negative pressure is formed in the space below the movable ring, sucking the heat-conducting agent back into the storage cavity to realize the reuse of the heat-conducting agent.

[0010] The preferred solution of the rotational heat dissipation device for the defoaming machine in the present invention is as follows: An annular steel mesh is provided in the gap, and the upper and lower ends of the annular steel mesh are respectively located between the lower end of the middle fixing ring and the bottom wall of the outer shell. The thickness of the annular steel mesh is less than the width of the gap. The function of the annular steel mesh is to fill the gap and prevent the lateral support area of the inner tank from being insufficient due to an overly large gap. Additionally, the annular steel mesh itself serves as a heat-conducting material, and the heat-conducting agent is filled in the holes of the annular steel mesh, between the annular steel mesh and the inner tank, and between the annular steel mesh and the lower fixing ring, reducing the amount of heat-conducting agent used.

[0011] The preferred solution of the rotational heat dissipation device for the defoaming machine in the present invention is as follows: The bottom wall of the inner tank is provided with inwardly extending positioning holes. There are at least two positioning holes, and the bottom wall of the outer shell is provided with positioning posts corresponding to all the positioning holes one by one. Each positioning hole forms a hollow positioning tube on the inner side of the inner tank. The functions of the positioning tube are as follows: Firstly, for centrifugal movement, when the material flows in the inner tank, the positioning tube plays a role in stirring the material and increasing the heat-conducting contact area. Secondly, after the positioning post is inserted into the positioning tube, the positioning post strengthens the structural strength of the inner tank and reduces the probability of deformation of the inner tank.

[0012] The preferred solution of the rotational heat dissipation device for the defoaming machine in the present invention is as follows: The bottom wall of the outer shell is provided with exhaust holes, and the bottom wall of the inner tank is provided with plugs corresponding to the exhaust holes. During the downward flow of the heat-conducting agent, the air between the inner tank and the outer shell is discharged from the exhaust holes. When the inner tank descends to the lowest point, the plug just inserts into the exhaust hole, and the heat-conducting agent just flows to the exhaust hole, preventing the heat-conducting agent from overflowing.

[0013] The preferred solution of the rotational heat dissipation device for the defoaming machine in the present invention is as follows: The outer side of the outer shell is provided with heat dissipation fins and positioning pins for locking the inner tank. After the inner tank descends to the lowest point, the positioning pins are horizontally inserted into the corresponding locking holes of the inner tank, and the springs of all the elastic telescopic shafts are kept in a compressed state.

[0014] The beneficial effects of the rotational heat dissipation device for the defoaming machine in the present invention are as follows: 1. The inner tank is made of heat-conducting plastic, and the outer shell is made of a metal material with a high heat-conductivity coefficient such as aluminum alloy or stainless steel. A heat-conducting agent is filled between the inner tank and the outer shell to solve the problem of large interfacial thermal resistance. The heat generated by the material is quickly transferred from the inner tank and the heat-conducting agent to the outer shell. The outer shell has a fast heat dissipation speed, thereby improving the heat dissipation efficiency of the inner tank, increasing the heat dissipation speed of the material, and reducing the probability of material deterioration.

[0015] 2. The heat-conducting agent is pre-loaded into the storage cavity. During the process of inserting the inner container into the outer shell, the heat-conducting agent is squeezed into the gap and the space between the bottom wall of the inner container and the outer shell, replacing the existing manual operation of coating the heat-conducting material. After the defoaming operation is completed, pull the inner container outward slightly with a little force, and the inner container can be easily taken out of the outer shell under the elastic force of the elastic telescopic shaft. During the process of taking out the inner container, the movable ring moves upward, and the heat-conducting agent attached to the side of the inner container is scraped off by the middle fixing ring. At the same time, the heat-conducting agent is sucked back into the storage cavity. The heat-conducting agent at the bottom of the inner container is also recovered, but a small amount of heat-conducting agent remains at the bottom. The amount of the remaining heat-conducting agent at the bottom is extremely small. Compared with the existing defoaming barrel, the amount of wasted heat-conducting agent is greatly reduced, and only the bottom of the inner container needs to be cleaned. Therefore, the overall operation steps are reduced, the consumption of the heat-conducting agent per time is reduced, the efficiency of the batch defoaming operation is improved, and the cost is reduced.

Detailed implementation manners

[0019] In view of the deficiencies in the prior art, the inventors of this case have proposed the technical solution of the present invention through long-term research and a large number of practices. The following will further explain the technical solution, its implementation process and principle in combination with the drawings in the embodiments of the present application and specific implementation cases.

[0020] As Figure 1 shown, this embodiment provides a rotating heat dissipation device for a defoaming machine, including an inner container 1 with an open upper end and an outer shell 2 with an open upper end. The inner container 1 is made of heat-conducting plastic, and the outer shell 2 is made of a metal material with a high heat conduction coefficient such as aluminum alloy or stainless steel, but is not limited to heat-conducting plastic. As long as the material of the inner container 1 meets the requirements of not reacting with the material and having a relatively high heat conduction coefficient, similarly, the material of the outer shell 2 is not limited to aluminum alloy and stainless steel. The shapes of the outer shell 2 and the inner container 1 are both cylindrical. Heat dissipation fins 201 are distributed on the outer side of the outer shell 2. During the centrifugation process, the heat dissipation fins 201 disturb the air and improve the heat dissipation speed of the outer shell 2.

[0021] The inner container 1 in this embodiment is inserted into the inner cavity of the outer shell 2, and then the outer shell 2 is placed in the centrifugal disk of the defoaming machine. Usually, the centrifugal disk is provided with at least two centrifugation stations, and each operation needs to be placed symmetrically to keep the centrifugal disk rotating smoothly.

[0022] The specific connection relationship between the outer shell 2 and the inner container 1 is as follows: As shown in Figure 2 , 4 , Figure 5 and Figure 6 shown, on the outer side of the upper part of the inner container 1, there are downwardly directed guide posts 101, and there are eight guide posts 101. The eight guide posts 101 are evenly distributed along the circumferential direction of the inner container 1. The upper end of the outer shell 2 is provided with guide holes 202 corresponding to all the guide posts 101 one by one. The guide posts 101 and the guide holes 202 can quickly align the inner container 1 and the outer shell 2, improving the efficiency of batch defoaming operations.

[0023] In the middle and lower parts inside the outer shell 2, an intermediate fixing ring 203 and a lower fixing ring 204 adapted to the barrel body of the inner container 1 are respectively provided. The cross-section of the intermediate fixing ring 203 is in the shape of a "7". The upper end of the intermediate fixing ring 203 is fixedly connected to the inner surface of the outer shell 2. The space between the intermediate fixing ring 203 and the lower fixing ring 204 is a storage cavity 205, and a piston cavity 206 is formed between the intermediate fixing ring 203 and the outer shell 2. In fact, the piston cavity 206 is a part of the storage cavity 205. Specifically, the upper part of the storage cavity 205 is the piston cavity 206. An activity ring 207 that can slide up and down is provided in the upper part of the storage cavity 205. The two side surfaces of the activity ring 207 are respectively in sliding seal with the side surface of the intermediate fixing ring 203 and the side surface of the outer shell 2, that is, the activity ring 207 slides up and down in the piston cavity 206. The lower end surface of the activity ring 207 is an inclined surface, which is convenient for shoveling the heat-conducting agent. The upper end surface of the intermediate fixing ring 203 is a plane. Eight groups of elastic telescopic shafts 208 are provided at the upper end of the intermediate fixing ring 203. Each group consists of two elastic telescopic shafts 208, for a total of sixteen elastic telescopic shafts 208. The structure of each elastic telescopic shaft 208 is the same. Each elastic telescopic shaft 208 includes a spring 209 and a telescopic rod 210. The intermediate fixing ring 203 is provided with through holes corresponding to each telescopic rod 210 one by one. Each spring 209 is sleeved on the corresponding telescopic rod 210. Above the intermediate fixing ring 203, a retaining ring 211 fixedly connected to the upper ends of all the telescopic rods 210 is provided. The lower ends of all the telescopic rods 210 are inserted into the corresponding through holes one by one, and the lower ends of all the telescopic rods 210 are fixedly connected to the activity ring 207, so that all the springs 209 are located between the retaining ring 211 and the intermediate fixing ring 203. The function of the retaining ring 211 is to make all the telescopic rods 210 lift and lower synchronously, and at the same time prevent the telescopic rods 210 from falling off.

[0024] As Figure 3 and Figure 5 shown, a gap is provided between the lower fixing ring 204 and the side wall of the inner container 1, and the storage cavity 205 communicates with the gap. Further, an annular steel mesh 212 is provided in the gap. The annular steel mesh 212 itself is full of holes, which is convenient for the heat-conducting agent to flow. The upper end and the lower end of the annular steel mesh 212 are respectively located between the lower end of the intermediate fixing ring 203 and the bottom wall of the outer shell 2. After the inner container 1 is inserted into the outer shell 2, although the thickness of the annular steel mesh 212 is less than the width of the gap, the annular steel mesh 212 still plays a supporting role on the side wall of the inner container 1 during the centrifugal movement.

[0025] The operation method of the rotating heat dissipation device in this embodiment is as follows: First, a heat-conducting agent is pre-filled in the storage cavity 205. The heat-conducting agent is viscous and can flow.

[0026] Then, the guide post 101 of the inner tank 1 is inserted along the guide hole 202, and the inner tank 1 is continuously pressed down. The inner tank 1 squeezes the retaining ring 211 to move downward, all the springs 209 are compressed, and at the same time, all the telescopic shafts push the movable ring 207 to move downward. The heat-conducting agent in the storage cavity 205 flows into the gap and the space between the bottom wall of the inner tank 1 and the outer shell 2 under the extrusion of the movable ring 207, and at the same time fills the holes of the annular steel mesh 212, between the annular steel mesh 212 and the inner tank 1, and between the annular steel mesh 212 and the lower fixing ring 204, greatly reducing the interfacial thermal resistance.

[0027] Then, an even number of rotating heat dissipation devices are symmetrically placed in the centrifugation station. If the number of rotating heat dissipation devices is odd, counterweights of equal mass need to be used instead.

[0028] Finally, the defoaming machine is started. After the set time of centrifugal motion, the outer shell 2 is taken out, and then the inner tank 1 is taken out from the outer shell 2. During the process of taking out the inner tank 1, the elastic force of the spring 209 is released, and the pulling force required to take out the inner tank 1 is very small. At the same time, a negative pressure is formed in the space below the movable ring 207 during the taking-out process, sucking the heat-conducting agent back into the storage cavity 205, realizing the reuse of the heat-conducting agent. At the same time, very little heat-conducting agent remains on the outer surface of the inner cylinder. Compared with the existing defoaming method, the amount of wasted heat-conducting agent is greatly reduced, and only the bottom of the inner tank 1 needs to be cleaned.

[0029] As can be seen from the above operations, after the inner tank 1 is pressed to the lowest point, the current position of the inner tank 1 needs to be maintained, that is, it cannot be reset under the elastic force of the spring 209. To meet this requirement, the outer shell 2 is provided with a positioning pin 213 for locking the inner tank 1. The positioning pin 213 is arranged radially. The inner tank 1 is provided with a locking hole 104 corresponding to the positioning pin 213. After the inner tank 1 descends to the lowest point, the positioning pin 213 is horizontally inserted into the corresponding locking hole 104 of the inner tank 1, and the springs 209 of all the elastic telescopic shafts 208 remain in a compressed state. Conversely, after the positioning pin 213 is taken out, the inner cylinder can be withdrawn from the outer shell 2 under the elastic force, effectively solving the problem that the inner tank 1 cannot be quickly taken out due to the adhesion of the heat-conducting agent, which affects the efficiency of batch defoaming operations. In addition, as Figure 5 and Figure 7 shown, an exhaust hole 214 is provided on the bottom wall of the outer shell 2, and a plug 102 corresponding to the exhaust hole 214 is provided on the bottom wall of the inner tank 1. During the process of the heat-conducting agent flowing downward, the air between the inner tank 1 and the outer shell 2 is discharged from the exhaust hole 214. When the inner tank 1 descends to the lowest point, the plug 102 just inserts into the exhaust hole 214, and the heat-conducting agent just flows to the exhaust hole 214, avoiding the overflow of the heat-conducting agent. A plurality of exhaust grooves 216 connected to the exhaust hole 214 are provided on the bottom wall of the outer shell 2, and all the exhaust grooves 216 are radially distributed.

[0030] To solve the problem of deformation of the inner tank 1 during centrifugal motion, as Figure 5 , 6 andFigure 7 As shown, positioning holes 105 extending inwards are provided on the bottom wall of the inner container 1. There are sixteen positioning holes 105, and positioning posts 215 corresponding to all the positioning holes 105 are provided on the bottom wall of the outer shell 2. Each positioning hole 105 forms a hollow positioning tube 103 on the inner side of the inner container 1. The functions of the positioning tube 103 are as follows: firstly, for centrifugal movement, when materials flow in the inner container 1, the positioning tube 103 plays a role in stirring the materials and increasing the heat conduction contact area. Secondly, after the inner container 1 is inserted into the outer shell 2, the upper part of the inner container 1 is supported by eight guide posts 101, and the lower part of the inner container 1 is supported by sixteen positioning posts 215, thereby strengthening the overall structural strength of the inner container 1 and reducing the probability of deformation of the inner container 1.

[0031] It should be understood that the above embodiments are only used to illustrate the technical concept and features of the present invention. The purpose is to enable those who are 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 only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or replacements can still be made. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
