Description

Technical Field

[0001] This utility model relates to the field of rosin precipitation technology, specifically a rosin precipitation pot. Background Technology

[0002] Rosin can be obtained from pine-like tree species around the world, especially longleaf pine, Cuban pine and sago pine produced in the southeastern United States. Slits are made in these trees to allow the highly viscous secretion, called rosin, to be distilled. This volatile liquid is turpentine, and the remaining hard resin is called rosin.

[0003] In rosin production, rosin resin is processed to separate and purify the resin. The resin is melted at 93-95°C. During the melting process, appropriate amounts of water, turpentine, and oxalic acid are added. Water is added to wash away water-soluble pigments and tannins in the resin, while oxalic acid is added to remove colored resin iron salts. The amount of oxalic acid used is 0.05%-0.15% of the resin weight. The addition of turpentine can better melt the resin and reduce the density and viscosity of the resin solution. After dissolution and mixing, the treated liquid mixture needs to be transported to a settling tank for stratification. The dissolved turpentine layer is then separated and distilled to obtain pure rosin.

[0004] Existing sedimentation pots for precipitating dissolved mixed solutions utilize the principle of different densities between substances to achieve natural sedimentation and stratification. However, natural sedimentation and stratification takes a long time, resulting in low sedimentation efficiency for mass production of rosin, thus reducing the yield of rosin. Utility Model Content

[0005] The purpose of this invention is to provide a rosin sedimentation pot to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rosin sedimentation pot, comprising a sedimentation pot body and a centrifuge tank. A drive motor is mounted on the top of the sedimentation pot body, and the drive motor is fixedly connected to the sedimentation pot body by a motor frame; both ends of the centrifuge tank are rotatably connected inside the sedimentation pot body, and the bottom shaft of the drive motor is fixedly connected to the top of the centrifuge tank; a feeding port is provided on the top of the centrifuge tank, and a feeding structure is provided on the top of the centrifuge tank; the feeding structure includes:

[0007] The fixing frame is connected at its bottom to the top of the sedimentation tank body;

[0008] A cylinder, the cylinder body of which is mounted on the inner side of a fixed frame;

[0009] A connecting pipe, which is mounted on top of the mounting bracket;

[0010] A flexible hose, one end of which is connected to the end of a connecting pipe;

[0011] The feed pipe is connected to the other end of the hose, and the telescopic rod of the cylinder is fixed to the outer wall of the feed pipe by a connecting strip;

[0012] The rosin sedimentation pot has a centrifugal state and a feeding state;

[0013] When the rosin sedimentation tank is in centrifugal state, the cylinder contracts to make the feed pipe leave the feed port, and the centrifuge tank rotates rapidly.

[0014] When the rosin sedimentation pot is in the feeding state, the feeding port is stopped below the feeding pipe, and the cylinder extends and retracts to insert the feeding pipe into the feeding port to deliver the solution.

[0015] By adopting the above technical solution, the cylinder extends and retracts to push the feed pipe into the feeding port and add an appropriate amount of mixed solution. The drive motor drives the centrifuge tank to rotate rapidly. When the mixed solution inside receives the centrifugal force of rotation, the liquids of different densities will be centrifuged and separated into layers quickly. After the centrifugation stops and the mixture remains still for a period of time, the layers will stabilize and the separated liquids will be discharged in sequence. By changing the static state of the existing technology to centrifugation through the above structure, the time for the rosin mixed solution to separate into layers can be reduced.

[0016] Preferably, a bearing is fixedly installed on the inner wall of the bottom end of the sedimentation tank body, and a discharge ring is fixedly connected to the bottom end of the centrifuge tank, with the outer wall of the discharge ring sleeved on the inner ring of the bearing.

[0017] By adopting the above technical solution, the discharge ring can be fixedly supported on the bearing by installing a bearing at the bottom, which improves the smoothness of the centrifuge when rotating rapidly and reduces the noise generated by rotational vibration.

[0018] Preferably, a high-temperature resistant rubber blade is connected to the inner side of the feeding port, and an anti-overflow pipe is fixedly connected to the feeding port position at the top of the centrifuge tank.

[0019] By adopting the above technical solution, a high-temperature resistant rubber blade is connected around the feed pipe. When the feed pipe descends, the rubber blade can be pushed open to add rosin mixture solution inside. When it leaves, it can return to its shape to block the feed port solution, preventing the rosin mixture solution from rotating and flying out. When combined with the anti-overflow pipe, it can prevent the solution from flying out during rotation, reducing the probability of the mixture solution causing internal contamination.

[0020] Preferably, a support frame is fixedly installed at the bottom of the sedimentation pot body, and a discharge pipe is installed at the bottom of the sedimentation pot body, wherein the discharge pipe channel is connected to the discharge ring channel.

[0021] By adopting the above technical solution, the installation support frame can support the main body of the sedimentation tank, improve the stability of the centrifuge tank during centrifugation, and by installing a discharge pipe at the bottom, it can be connected to an external conveying pipe, which facilitates the control of the discharge of the internal stratified solution.

[0022] Preferably, the bottom support plate of the support frame is fixed with a controller, the interior of the sedimentation pot body is equipped with a heating wire, and the drive motor is a YE3 vertical stepper motor.

[0023] By adopting the above technical solution, the temperature of the heating wire can be controlled by installing a controller, so that the internal temperature of the sedimentation pot body can reach the same level as the rosin mixed solution, avoiding the problem of the solution becoming viscous due to low temperature. At the same time, the stepper motor can be controlled to rotate, and the feeding port can be controlled to stop below the feed pipe to transport the mixed solution.

[0024] Preferably, the hose can be an NBR food-grade high-temperature conveying hose, and the anti-overflow hose is L-shaped with its opening facing the inside of the centrifuge tank.

[0025] By adopting the above technical solution and using a high-temperature resistant food-grade conveying pipe, the problem of toxic substances overflowing from the hose at high temperatures and affecting the quality of rosin can be avoided. At the same time, the anti-overflow pipe is L-shaped with the opening facing inward, which can reduce the probability of solution entering the anti-overflow pipe during rotation and prevent the solution from flying out of the feeding port.

[0026] Preferably, the top inner wall of the sedimentation tank body has a protruding limiting ring, and the top of the centrifuge tank is inside the limiting ring.

[0027] By adopting the above technical solution, the structure can limit the top of the centrifuge tank, improve the stability of the centrifuge tank during rotation, and reduce the noise caused by vibration when the centrifuge tank rotates.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] (1) The feed pipe is pushed into the feeding port by the extension and retraction of the cylinder, and an appropriate amount of mixed solution is added inside. The centrifuge tank is driven to rotate rapidly by the drive motor. When the mixed solution inside is subjected to the centrifugal force of rotation, the liquids of different densities will be centrifuged and separated into layers quickly. After the centrifugation stops, the layers are allowed to stand still for a period of time and then the layers are stabilized. The separated liquids are then discharged in sequence. By changing the static sedimentation and layering of the existing technology to centrifugal sedimentation and layering through the above structure, the time for the rosin mixed solution to be separated into layers can be reduced, the efficiency of the rosin mixed solution to be separated into layers can be improved, and the production yield of rosin can be increased.

[0030] (2) By using a hose to connect the connecting pipe and the feed pipe at both ends, the position of the feed pipe can be moved under the action of the cylinder, and the rosin mixture solution is conveyed into the interior through the feeding port, thereby realizing non-contact conveying of the rosin mixture solution to the rotatable centrifuge, ensuring the normal operation of adding raw materials to the centrifuge.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0038] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model is a rosin sedimentation pot, which includes a sedimentation pot body 1 and a centrifuge tank 2.

[0039] A drive motor 3 is installed on the top of the sedimentation tank body 1. The drive motor 3 is fixedly connected to the sedimentation tank body 1 by a motor frame. The drive motor 3 is used to provide power to drive the centrifugal structure to rotate and centrifuge for stratification.

[0040] The centrifuge tank 2 is rotatably connected to the inside of the sedimentation tank body 1 at both ends. The centrifuge tank 2 can rotate and centrifuge in the sedimentation tank body 1 to perform rotational centrifugation and stratification of the rosin mixed solution contained inside. The bottom shaft of the drive motor 3 is fixedly connected to the top of the centrifuge tank 2. The top of the centrifuge tank 2 is provided with a feeding port 4, which is used to add the rosin mixed solution into the centrifuge tank 2 for centrifugation and stratification. The top of the centrifuge tank 2 is provided with a feeding structure 6.

[0041] Feed structure 6 includes:

[0042] Fixing bracket 601, the bottom of fixing bracket 601 is connected to the top of sedimentation tank body 1;

[0043] Cylinder 602, the main body of cylinder 602 is installed inside the fixed frame 601. Cylinder 602 is used to push the feeding structure into the feeding port 4 to transport the rosin mixed solution for stratification and sedimentation.

[0044] Connecting pipe 603 is installed on the top of the fixed frame 601. Connecting pipe 603 is used to connect to the conveying pipe of the previous process and can convey to this device.

[0045] 604 stainless steel hose;

[0046] The two ends of the feed pipe 605 and the hose 604 are respectively connected to the connecting pipe 603 and the feed pipe 605. The telescopic rod of the cylinder 602 is fixed to the outer wall of the feed pipe 605 with the connecting strip. The position of the feed pipe 605 can be moved by the action of the cylinder 602, and the rosin mixed solution is conveyed into the interior through the feeding port 4.

[0047] The rosin sedimentation tank has a centrifugal state and a feeding state. In the centrifugal state, the cylinder 602 retracts to make the feed pipe 605 leave the feeding port 4, and the centrifuge tank 2 rotates rapidly. In the feeding state, the feeding port 4 stops below the feed pipe 605, and the cylinder 602 extends and retracts to make the feed pipe 605 insert into the feeding port 4 to transport the solution. By changing the existing static sedimentation and stratification technology to centrifugal sedimentation and stratification, the time for rosin mixed solution stratification can be reduced, the efficiency of stratification and sedimentation of rosin mixed solution can be improved, thereby increasing the production yield of rosin.

[0048] Please see Figure 2 and Figure 4A bearing 8 is fixedly installed on the inner wall of the bottom end of the sedimentation tank body 1. A discharge ring 7 is fixedly connected to the bottom end of the centrifuge tank 2. The outer wall of the discharge ring 7 is sleeved on the inner ring of the bearing 8. The installation of the bearing 8 allows the discharge ring 7 to be fixedly supported on the bearing 8, improving the smoothness of the centrifuge tank 2 during rapid rotation and reducing the noise generated by rotational vibration. A high-temperature resistant rubber blade is connected to the inner side of the feed port 4. When the feed pipe 605 descends, it can push open the rubber blade to add the rosin mixture solution inside. When it leaves, it can return to its shape to block the solution at the feed port 4, preventing the rosin from mixing. The solution rotates and flies out. An anti-overflow pipe 5 is fixedly connected to the feed port 4 at the top of the centrifuge tank 2. The anti-overflow pipe 5 can prevent the solution from flying out during rotation, reducing the probability of mixed solution causing internal contamination. A support frame 12 is fixedly installed at the bottom of the sedimentation tank body 1. A discharge pipe 9 is installed at the bottom of the sedimentation tank body 1. The channel of the discharge pipe 9 is connected to the channel of the discharge ring 7. The support frame 12 can support the sedimentation tank body 1 and improve the stability of the centrifuge tank 2 during centrifugation. By installing the discharge pipe 9 at the bottom, it can be connected to an external conveying pipe to facilitate the control of the discharge of the internal stratified solution.

[0049] Example 2, please refer to Figure 2 and Figure 3 The bottom support plate of the support frame 12 is fixed with a controller 11. A heating wire 10 is installed inside the sedimentation tank body 1. The controller 11 can control the temperature of the heating wire 10 to ensure that the internal temperature of the sedimentation tank body 1 reaches the same level as the rosin mixed solution, thus avoiding the problem of the solution becoming viscous due to a lower temperature. The drive motor 3 is a YE3 vertical stepper motor. Controlling the stepper motor to rotate can control the feeding port 4 to stop below the feeding pipe 605 to transport the mixed solution. The hose 604 can be an NBR food-grade high-temperature conveying pipe, using a high-temperature resistant food-grade conveying hose. The tube can prevent the toxic substances from overflowing from the 604 hose at high temperatures, which could affect the quality of the rosin. The anti-overflow tube 5 is L-shaped, and the opening of the anti-overflow tube 5 faces the inside of the centrifuge tank 2. The L-shaped opening of the anti-overflow tube 5 can reduce the probability of the solution entering the anti-overflow tube 5 during rotation, and prevent the solution from flying out of the feed port 4. There is a protruding limiting ring on the top inner wall of the sedimentation tank body 1. The top of the centrifuge tank 2 is inside the limiting ring. This structure can limit the top of the centrifuge tank 2, improve the stability of the centrifuge tank 2 during rotation, and reduce the noise caused by vibration when the centrifuge tank 2 rotates.

[0050] Working principle: During use, the controller 11 controls the drive motor 3 to stop the feeding port 4 below the feed pipe 605. The cylinder 602 extends and pushes the feed pipe 605. With the extension of the hose 604, the feed pipe 605 delivers the rosin mixture solution into the centrifuge tank 2 through the feeding port 4. The drive motor 3 drives the centrifuge tank 2 to rotate rapidly, which can centrifuge and precipitate the rosin mixture solution inside into layers. After the layers are separated, wait for a period of time to allow the layers to stabilize, and then discharge the different layered solutions through the external valve at one end of the discharge pipe 9.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
