Description

Technical Field

[0001] The present invention relates to the technical field of dynamic mixing technology devices, and in particular to a two-stage dynamic mixer and a control method thereof. Background Art

[0002] The materials used in the molding process of polymer materials are usually composed of different polymers, fillers, additives, etc., so mixing is an inevitable stage in the molding process of polymer materials. The mixing of polymer materials is usually achieved by mixing the components in a continuous mixing device or an intermittent mixing device. At present, most of the mixers used in industry are single-type mixers, and are mostly used in the petrochemical, oil, mining and metallurgy industries. If such mixers are used in the viscose industry, low-viscosity mixers are selected, the flow time of the viscose is short, the pressure drop is small, but the mixing times do not meet the requirements and the mixing is uneven. If high-viscosity mixers are selected, the viscose is mixed more times, but the pressure drop is large, the degree of maturity changes greatly, and the quality of the finished product is affected. Moreover, the viscosity of the viscose changes greatly, so it is not suitable for use.

[0003] At present, static mixers are generally used to mix different fluids. The mixing unit fixed in the tube is used to change the flow state of the fluid in the tube to achieve good dispersion and sufficient mixing between different fluids. In order to achieve the mixing effect, the static mixer requires a relatively large volume, thereby increasing the pressure drop. The static mixer only changes the flow state of the fluid itself in the tube, has a poor mixing effect, cannot be disassembled, and is not easy to clean.

[0004] Its dynamic mixer unit is not mature yet and cannot produce colored yarns. Some dynamic mixers are not suitable for high temperature and high pressure melts. There are molded dynamic mixers for sale in the international market, but from the information learned from the market, the company's production scale is very small, the product price is high, and it is difficult to maintain. Currently, there are not many applications.

[0005] The existing dynamic mixers in the market are mainly single-stage mixers, that is, one inlet and one outlet. In order to reduce the pressure drop, the pipe path is generally short. In some special working conditions, the shorter pipe path may not achieve the required mixing effect. The solution is often a single-stage dynamic mixer plus a static mixer. The other is to connect two single-stage dynamic mixers in series. No matter which solution is used, it occupies a large area and consumes a lot of energy, and is expensive. Summary of the invention

[0065] See also Figure 1-3 As shown, in some embodiments of the present application, this embodiment provides a two-stage dynamic mixer, comprising:

[0066] Base 100;

[0067] A material heating device, located on the side of the base 100 and detachably connected to the base 100;

[0068] A mixer, the mixer comprising a primary dynamic mixer 110 and a secondary dynamic mixer 120, the primary dynamic mixer 110 and the secondary dynamic mixer 120 are arranged on one side of the top of the base 100; the primary dynamic mixer 110 and the secondary dynamic mixer 120 are both used for mixing materials;

[0069] A dual-output shaft reducer 130 is located at the top of the base 100 and in the middle of the base 100. The first output end of the dual-output shaft reducer 130 is connected to the primary dynamic mixer 110 through a first connector 170160, and the second output end of the dual-output shaft reducer 130 is connected to the secondary dynamic mixer 120 through a second connector. The dual-output shaft reducer 130 is used to drive the primary dynamic mixer 110 and the secondary dynamic mixer 120 to operate;

[0070] The motor 140 is located at the other side of the top of the base 100, and the output end of the motor 140 is connected to the dual-output shaft reducer 130, and the motor 140 is used to drive the dual-output shaft reducer 130 to operate;

[0071] The control device 150 is located on the side of the base 100 and is connected to the material heating device, the first-stage dynamic mixer 110, the second-stage dynamic mixer 120, the dual-output shaft reducer 130 and the motor 140. The control device 150 is used to control the operating state and parameter settings of the mixer.

[0072] It can be seen that the base 100 is used to provide stable support, which can ensure the stability of the entire device during operation; the material heating device can evenly heat the material to be mixed, and the material heating device has a temperature sensor for measuring the temperature of the material, thereby achieving precise control of the temperature; the mixer includes a primary dynamic mixer 110 and a secondary dynamic mixer 120, which are used to achieve efficient mixing of materials; the dual-output shaft reducer 130 can provide stable power output to ensure the smooth operation of the mixer; the motor 140 serves as a power source to provide power for the entire system; the control device 150 is responsible for the intelligent control of the entire mixer to ensure the accuracy and efficiency of the mixing process.

[0073] Specifically, the primary dynamic mixer 110 includes:

[0074] A first housing 111;

[0075] A first main shaft is arranged in a direction parallel to the length direction of the first shell 111, and the first main shaft includes a first large diameter section 1121 and a first small diameter section 1122, one end of the first large diameter section 1121 is connected to the first output end of the dual-output shaft reducer 130, and the other end of the first large diameter section 1121 extends into the first shell 111 and is connected to the first small diameter section 1122; wherein a mixing cavity 113 is formed between the first small diameter section 1122 and the first shell 111;

[0076] A first inlet 114 is provided on one side of the first shell 111 along the length direction of the first shell 111 , and the first inlet 114 is located on one side of the first small diameter section 1122 close to the first large diameter section 1121 ;

[0077] The first outlet 115 is provided at one end of the first shell 111 away from the first connector 170160. A first discharge nozzle 1151 is provided inside the first outlet 115. The first discharge nozzle 1151 is connected to the other end of the first small-diameter section 1122.

[0078] The first propelling teeth 116 are evenly arranged on one side of the first small diameter section 1122 along the axial direction of the first small diameter section 1122, and one end of the first propelling teeth 116 is connected to the first large diameter section 1121, and the other end of the first propelling teeth 116 faces the mixing chamber 113;

[0079] The first movable teeth 117 are evenly arranged on the other side of the first small-diameter section 1122 along the axial direction of the first small-diameter section 1122 , and the first movable teeth 117 are located in the mixing cavity 113 ;

[0080] The first stator teeth 118 are evenly arranged on the inner wall of the mixing chamber 113 along the axial direction of the first small-diameter section 1122 , and the first stator teeth 118 are matched with the first movable teeth 117 .

[0081] Specifically, the secondary dynamic mixer 120 includes:

[0082] a second shell;

[0083] A second main shaft is arranged in a direction parallel to the length direction of the second shell, the second main shaft comprises a second large diameter section and a second small diameter section, one end of the second large diameter section is connected to the output end of the dual output shaft reducer 130, and the other end of the second large diameter section extends into the second shell and is connected to the second small diameter section; wherein a mixing cavity 113 is formed between the second small diameter section and the second shell;

[0084] A second inlet 121 is provided on one side of the second shell along the length direction of the second shell, and the second inlet 121 is located on a side of the second small diameter section close to the second large diameter section;

[0085] A second outlet 122 is provided at one end of the second shell body away from the second connector, a second discharge nozzle is provided inside the second outlet 122, and the second discharge nozzle is connected to the other end of the second small diameter section;

[0086] A second propelling tooth is evenly arranged on one side of the second small diameter segment along the axial direction of the second small diameter segment, and one end of the second propelling tooth is connected to the second large diameter segment, and the other end of the second propelling tooth faces the mixing chamber 113;

[0087] second mover teeth, which are evenly arranged on the other side of the second small-diameter segment along the axial direction of the second small-diameter segment, and the second mover teeth are located in the mixing cavity 113;

[0088] The second stator teeth are evenly arranged on the inner wall of the mixing cavity 113 along the axial direction of the second small-diameter section, and the second stator teeth are matched with the second mover teeth.

[0089] It can be seen that the design of the first-stage dynamic mixer 110 and the second-stage dynamic mixer 120 enables the materials to be fully stirred and mixed during the mixing process, thereby improving the mixing efficiency and quality; the setting of the first propulsion teeth 116 and the second propulsion teeth facilitates the flow of materials in the mixing chamber 113, ensuring that the materials can pass through the mixer evenly; the adaptation design of the first movable teeth 117 and the second movable teeth and the first stator teeth 118 and the second stator teeth further enhances the mixing effect, so that the materials can be fully sheared and dispersed during the mixing process.

[0090] Specifically, the first connector 170160 includes:

[0091] A first connecting frame 161 is arranged between the dual output shaft reducer 130 and the first housing 111 in a direction parallel to the length direction of the first housing 111, and two ends of the first connecting frame 161 are connected to the dual output shaft reducer 130 and the first housing 111 respectively;

[0092] A first cooling jacket spiral seal 162 is sleeved on the outside of the first large diameter section 1121 and located between the first connecting frame 161 and the first shell 111;

[0093] The first packing sealing layer 163 is sleeved on the outside of the first large diameter section 1121 , and the first packing sealing layer 163 is located inside the first connecting frame 161 . The first packing sealing layer 163 is located at one end of the first large diameter section 1121 close to the first shell 111 .

[0094] Specifically, the second connector includes:

[0095] A second connecting frame is arranged between the dual output shaft reducer 130 and the second housing in a direction parallel to the length direction of the second housing, and two ends of the second connecting frame are connected to the dual output shaft reducer 130 and the second housing respectively;

[0096] The second cooling jacket spiral seal is sleeved on the outside of the second large diameter section and located between the second connecting frame and the second shell;

[0097] The second packing sealing layer is sleeved on the outside of the second large diameter section, and the second packing sealing layer is located inside the second connecting frame. The second packing sealing layer is located at one end of the second large diameter section close to the second shell.

[0098] It can be seen that the design of the first connector 170160 and the second connector not only ensures the stability and sealing of the mixer, but also effectively prevents the leakage of materials during the mixing process through the dual protection of the cooling jacket spiral seal and the stuffing sealing layer, while reducing the influence of the heat generated by friction on the mixing effect; the cooling jacket spiral seal can effectively cool the main shaft of the mixer to ensure temperature control during the mixing process, while the stuffing sealing layer provides additional sealing protection to ensure the reliability of the mixer during long-term operation.

[0099] Specifically, the first inlet 114 and the second inlet 121 are disposed opposite to each other, or the first inlet 114 and the second inlet 121 are disposed opposite to each other.

[0100] It can be seen that the facing or back-to-back arrangement of the first inlet 114 and the second inlet 121 allows the material to enter the mixer from two different directions, increasing the contact area and mixing opportunities of the material during the mixing process, thereby further improving the mixing efficiency; the facing inlets allow the materials to collide with each other when entering the mixing chamber 113, increasing the shear force between the materials and facilitating uniform mixing of the materials; and the back-to-back arrangement allows the materials to form convection in the mixing chamber 113, facilitating rapid dispersion and mixing of the materials.

[0101] Specifically, the control device 150 includes:

[0102] The acquisition module 151 is used to acquire the material temperature data inside the material heating device, compare the material temperature data with the temperature threshold, and determine whether the material is suitable for adding to the mixer according to the comparison result;

[0103] The judging module 152 is used for collecting the performance data of the material when determining that the material is suitable for adding to the mixer, and judging the connection mode between the first inlet 114, the first outlet 115, the second inlet 121 and the second outlet 122 according to the performance data; wherein the performance data includes material density, material viscosity, material compression strength and material flow index;

[0104] The processing module 153 is used to add the material into the mixer after determining the connection status between the first outlet 115 and the second inlet 121 and the second outlet 122, and control the mixer to operate according to the preset operating parameters corresponding to each of the connection states.

[0105] It can be seen that the design of the control device 150 makes the entire mixing process more intelligent and automated. The acquisition module 151 can monitor the temperature of the material in real time to ensure that the material reaches the optimal mixing condition before entering the mixer; the judgment module 152 intelligently selects the appropriate connection method based on the performance data of the material to ensure the efficiency and uniformity of the mixing process; the processing module 153 accurately controls the operating state of the mixer according to the preset operating parameters, thereby realizing accurate control of the mixing process.

[0106] Specifically, judging whether the material is suitable for adding to the mixer according to the comparison result includes:

[0107] When the material temperature data is within the temperature threshold, it is determined that the material is suitable for adding to the mixer;

[0108] When the material temperature data is outside the temperature threshold, it is determined that the material is not suitable for adding into the mixer.

[0109] Specifically, collecting the performance data of the material and determining the connection status between the first outlet 115 and the second inlet 121 and the second outlet 122 according to the performance data include:

[0110] Preset a material parameter threshold, compare each item of the performance data with the material parameter threshold one by one, and determine the connection status between the first outlet 115 and the second inlet 121 and the second outlet 122 according to the comparison result;

[0111] When each item of the performance data is less than or equal to the material parameter threshold, the first outlet 115 and the second outlet 122 are connected in series through a pipeline;

[0112] When all data in the performance data are greater than the material parameter threshold, the first inlet 114, the first outlet 115, the second inlet 121 and the second outlet 122 are not connected;

[0113] When one or more of the data in the performance data are greater than the material parameter threshold, the first outlet 115 and the second inlet 121 are connected in series through the pipeline.

[0114] It can be seen that, through this intelligent judgment and connection mode selection based on material performance data, the mixer can be flexibly adjusted according to different material characteristics, so as to adapt to various mixing requirements. When the temperature and performance parameters of the material meet the requirements, the mixer can operate in the best state to ensure that the mixing effect reaches the expected goal. When the first outlet 115 and the second outlet 122 are connected in series through a pipeline, it means that the filler that needs to be mixed currently has poor performance (suitable for mixing high temperature, high viscosity, high pressure and other materials with poor fluidity). At the same time, this connection mode is also suitable for the process of adding different auxiliary materials in stages. Online mixing; when the first inlet 114, the first outlet 115, the second inlet 121 and the second outlet 122 are not connected, the outflowing materials can enter different devices respectively or merge into the next device, which can double the output without increasing the model and diversify the process; when the first outlet 115 and the second inlet 121 are connected in series through a pipeline, it means that the current filler performance is poor or difficult to mix.

[0115] See also Figure 4 As shown, in some embodiments of the present application, this embodiment provides a two-stage dynamic mixer control method, comprising the following steps:

[0116] S100: collecting material temperature data inside the material heating device, comparing the material temperature data with a temperature threshold, and judging whether the material is suitable for adding to the mixer according to the comparison result;

[0117] S200: when it is determined that the material is suitable for being added to the mixer, collecting performance data of the material, and judging the connection state between the first outlet and the second inlet and the second outlet according to the performance data; wherein the performance data includes material density, material viscosity, material compression strength and material flow index;

[0118] S300: After determining the connection status between the first outlet and the second inlet and the second outlet, adding the material into the mixer, and controlling the mixer to operate according to the preset operating parameters corresponding to each of the connection modes.

[0119] It can be seen that the control method of the mixer not only realizes real-time monitoring and dynamic adjustment of the mixing process, but also ensures that the quality of the final mixture meets the requirements. During the mixing process, real-time monitoring of the temperature and pressure inside the mixer can promptly discover and solve possible problems and ensure the stability of the mixing process.
