Description

Technical Field

[0001] This invention relates to the field of quantitative proportioning and mixing technology, specifically to an integrated machine for quantitative proportioning and mixing of enzyme preparation raw materials. Background Technology

[0002] Enzyme preparations are purified and processed biological products with catalytic functions, used to accelerate specific chemical reactions. They are widely used in food, medicine, industry, and environmental protection. Quantitative mixing of enzyme preparation raw materials refers to the process of uniformly mixing enzyme preparations (such as proteases, amylases, phytases, etc.) with carriers (such as starch, wheat bran, silicates) or functional excipients (such as brown sugar, protectants, stabilizers) according to precisely calculated mass or activity ratios to prepare premixed products (such as feed additives, industrial catalysts, or fermentation substrates) with uniform composition and controllable activity. The mixing of enzyme preparation raw materials is carried out using mixing equipment. In existing technology: Authorization Publication No. CN 210905802 U's patent discloses a quantitative mixing device, including a mixing cylinder and a discharge port. The discharge port is provided on the lower surface of the mixing cylinder, and a support leg is provided at the bottom end of the mixing cylinder. A sterilization component is provided on the side surface of the mixing cylinder. A first hopper is fixedly installed at the top of one side of the mixing cylinder, and a second hopper is fixedly installed at the top of the other side of the mixing cylinder. A mixing component is provided inside the mixing cylinder. In this invention, by setting up a mixing component, different materials enter the mixing cylinder. The material accumulated at the bottom of the mixing cylinder is driven by an auger and moves upward in the return cylinder. Subsequently, the material... The material flows downward from the top of the return cylinder, undergoing reciprocating mixing to achieve thorough mixing of different materials, improving mixing efficiency and quality, while ensuring good mixing uniformity and avoiding uneven material distribution. However, when the device quantitatively mixes enzyme preparation raw materials, the feeding position of the enzyme preparation raw materials in the mixing section is fixed, which causes the same type of enzyme preparation raw materials to easily gather in the same position during feeding. Subsequent stirring and dispersion will take a certain amount of time, indicating room for improvement. In addition, after long-term use, material aggregation may occur on the pipe wall of the feeding pipeline, affecting the mixing accuracy of enzyme preparation raw materials. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an integrated machine for quantitative proportioning and mixing of enzyme preparation raw materials. The device uses a transmission element to enable the enzyme preparation raw materials to be mixed and fed in a ring dispersion manner, thereby improving the mixing rate of enzyme preparation raw materials. At the same time, the device uses an air blowing element to feed the residual material in the conveying pipeline, thereby improving the mixing and proportioning accuracy of enzyme preparation raw materials and reducing the pipeline conveying blockage rate, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated machine for quantitative proportioning and mixing of enzyme preparation raw materials, including a frame, with horizontally symmetrically distributed storage hoppers on the upper side of the frame, a screw weighing feeder at the bottom of each storage hopper, a mixing shell on the bottom wall of the frame, and also including a feeding mechanism and an air blowing mechanism.

[0005] Feeding mechanism: It includes a hollow shaft, an upper shell, a lower shell, a guide shell, a through groove, and a feed pipe. The hollow shaft is rotatably connected to the top wall of the mixing shell through a sealed bearing. The lower outer end of the hollow shaft is provided with a lower shell. The lower end of the inner arc wall of the lower shell is provided with three annularly distributed guide shells. The bottom of each guide shell is provided with a through groove. The upper end of the lower shell is rotatably connected to the upper shell through a sealed bearing. The top wall of the mixing shell is provided with a feed pipe. The discharge port of the screw weighing feeder is connected to the upper end of the feed pipe through a material pipe. The lower end of the feed pipe is fixedly connected to the inner wall of the upper shell.

[0006] Air blowing mechanism: It is set between the frame, material pipe and mixing shell. The device uses a transmission element to mix and feed the enzyme preparation raw materials in a ring dispersion manner, thereby improving the mixing rate of the enzyme preparation raw materials. At the same time, the device uses an air blowing element to feed the residual material in the conveying pipe, thereby improving the mixing ratio accuracy of the enzyme preparation raw materials and reducing the pipe conveying blockage rate.

[0007] Furthermore, it also includes a controller, which is located outside the frame. The controller's input terminal is electrically connected to an external power source, and the controller is bidirectionally electrically connected to the screw weighing feeder, facilitating the control of the operation of the electrical components within the device.

[0008] Furthermore, the feeding mechanism also includes a conical seat, which is disposed on the bottom wall of the lower shell to guide the material in the lower shell of the integrated machine for quantitative mixing of enzyme preparation raw materials.

[0009] Furthermore, the feeding mechanism also includes a drive assembly, which includes a protective shell, a worm gear, a worm wheel, and a servo motor. The protective shell is located in the upper middle part of the mixing shell. The upper outer end of the hollow shaft is located inside the protective shell and is equipped with a worm wheel. The worm gear is rotatably connected between the left and right walls of the protective shell through a bearing. The worm gear meshes with the worm wheel. A servo motor is located on the right side of the protective shell. The input end of the servo motor is electrically connected to the output end of the controller. The output shaft of the servo motor is fixedly connected to the right end of the worm gear, providing power for the rotation of the hollow shaft inside the enzyme preparation raw material quantitative mixing machine.

[0010] Furthermore, the air blowing mechanism includes a connecting pipe, an air supply pipe, an air pump, and a breathable filter. The connecting pipe is located between the upper ends of the two material pipes. An air pump is provided on the upper side of the frame. The input end of the air pump is electrically connected to the output end of the controller. The air outlet of the air pump is connected to the middle of the connecting pipe through the air supply pipe. A breathable filter is provided on the top wall of the mixing shell to feed the residual material in the conveying pipe of the enzyme preparation raw material quantitative proportioning mixing machine.

[0011] Furthermore, the air blowing mechanism also includes a solenoid valve, which is connected in series to the upper end of the material pipe and the left and right ends of the connecting pipe. The input end of the solenoid valve is electrically connected to the output end of the controller to control the opening and closing of the material conveying and air conveying pipelines in the enzyme preparation raw material quantitative mixing machine.

[0012] Furthermore, a mixing shaft is rotatably connected inside the hollow shaft via a sealed bearing. A spiral stirring blade is provided at the lower end of the outer arc surface of the mixing shaft. A servo motor is provided on the upper side of the mixing shell via a bracket. The input end of the servo motor is electrically connected to the output end of the controller. The output shaft of the servo motor is fixedly connected to the upper end of the mixing shaft to stir the enzyme preparation raw materials in the enzyme preparation raw material quantitative proportioning mixing machine.

[0013] Furthermore, a second solenoid valve is installed through the middle of the bottom discharge pipe of the mixing shell. The input end of the second solenoid valve is electrically connected to the output end of the controller to control the opening and closing of the bottom discharge pipe of the mixing shell in the enzyme preparation raw material quantitative mixing machine.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This integrated machine for quantitative proportioning and mixing of enzyme preparation raw materials has the following advantages:

[0015] 1. When using the integrated mixing machine for quantitative proportioning of enzyme preparation raw materials, the device uses a transmission element to make the feeding part rotate horizontally in a ring around the center of the mixing shell. This causes the fed enzyme preparation raw materials to fall layer by layer along the cross-section of the mixing shell in a ring-like dispersion. By increasing the initial dispersion of the enzyme preparation raw materials in the mixing shell, the time required for subsequent mixing of the enzyme preparation raw materials is reduced, thereby increasing the mixing and preparation rate of the enzyme preparation raw materials.

[0016] 2. When using the integrated mixing machine for quantitative proportioning of enzyme preparation raw materials, the device uses an air blowing element to blow high-pressure air along the conveying pipe from top to bottom. The high-pressure airflow carries the residual material in the conveying pipe into the mixing shell. By reducing the residual material rate in the conveying pipe, the mixing accuracy of enzyme preparation raw materials is improved. At the same time, by reducing the residual material in the conveying pipe, the probability of material blockage caused by material residue is reduced. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-4This embodiment provides a technical solution: an integrated machine for quantitative mixing of enzyme preparation raw materials, including a frame 1. The upper side of the frame 1 is provided with horizontally symmetrically distributed storage hoppers 3. Each storage hopper 3 has a screw weighing feeder 4 at its bottom inlet. The bottom wall of the frame 1 is provided with a mixing shell 6. The machine also includes a controller 2, located outside the frame 1. The input terminal of the controller 2 is electrically connected to an external power source. The controller 2 is bidirectionally electrically connected to the screw weighing feeder 4. The controller 2 is fixed to an operating position around the device with screws. When using the device to quantitatively mix enzyme preparations and carriers, the material in the storage hopper 3 enters the feed inlet of the screw weighing feeder 4 through its bottom inlet under its own gravity. (The material stored in the left storage hopper 3 is granular enzyme preparation, such as granular protease, amylase, phytase, etc.; the material stored in the right storage hopper 3 is granular carrier, such as starch. The front wall of each storage hopper 3 is equipped with...) The system includes an observation window for observing the remaining material in the storage hopper 3, and a controller 2 that starts the screw weighing feeder 4 to quantitatively deliver the corresponding enzyme preparation or carrier. The screw weighing feeder 4 consists of a sealed conveying structure and a high-precision weighing sensor. The sealed conveying structure delivers granular materials, and the high-precision weighing sensor is located below the conveying trough or at the support structure. When the granular enzyme preparation or carrier passes through, the sensor monitors its weight in real time and converts the weight signal into an electrical signal, which is then transmitted to its own weighing control unit. The control unit of the screw weighing feeder 4, combined with the running speed of the screw conveyor, calculates the instantaneous flow rate and cumulative weight of the granular enzyme preparation or carrier and transmits the results to the controller 2 as an electrical signal. When the amount of granular enzyme preparation or carrier delivered reaches the required level, the controller 2 automatically shuts down the screw weighing feeder 4. The system also includes a feeding mechanism 7 and an air blowing mechanism 8.

[0024] like Figure 2-3 As shown, the feeding mechanism 7 includes a hollow shaft 71, an upper shell 72, a lower shell 73, a guide shell 74, a through groove 75, and a feed pipe 77. The hollow shaft 71 is rotatably connected to the top wall of the mixing shell 6 via a sealed bearing. The lower outer end of the hollow shaft 71 is provided with the lower shell 73. Three annularly distributed guide shells 74 are provided through the lower end of the inner arc wall of the lower shell 73. The bottom of each guide shell 74 is provided with a through groove 75. The upper end of the lower shell 73 is rotatably connected to the upper shell 72 via a sealed bearing. The top wall of the mixing shell 6 is provided with a feed pipe 77. The discharge port of the screw weighing feeder 4 is connected to the upper end of the feed pipe 77 through the feed pipe 5. The lower end of the feed pipe 77 is fixedly connected to the inner wall of the upper shell 72. The granular enzyme preparation or carrier enters the cavity formed by the upper shell 72 and the lower shell 73 through the feed pipe 77 along the corresponding feed pipe 5. Then the granular enzyme preparation or carrier is spread and falls into the mixing shell 6 through the through groove 75 at the bottom of the guide shell 74 along the guide shell 74.

[0025] like Figure 2-3 As shown, the feeding mechanism 7 also includes a conical seat 76, which is disposed on the bottom wall of the lower half shell 73. The conical seat 76 blocks the bottom wall plane of the lower half shell 73, so that the bottom of the lower half shell 73 is in an inclined state, preventing the material from entering the corresponding guide shell 74 along the conical inclined surface and reducing the probability of material stacking on the bottom wall of the lower half shell 73.

[0026] like Figure 3 As shown, the feeding mechanism 7 also includes a drive assembly 78, which includes a protective shell 781, a worm gear 782, a worm wheel 783, and a servo motor 784. The protective shell 781 is located in the upper middle part of the mixing shell 6. The upper outer end of the hollow shaft 71 is located inside the protective shell 781 and is equipped with a worm wheel 783. The worm gear 782 is rotatably connected between the left and right walls of the protective shell 781 through a bearing. The worm gear 782 is meshed with the worm wheel 783. The servo motor 784 is located on the right side of the protective shell 781. The input end of the servo motor 784 is electrically connected to the output end of the controller 2. The output shaft of the servo motor 784 is fixedly connected to the right end of the worm gear 782. The controller 2 starts the servo motor 784 so that its output shaft drives the worm gear 782 to rotate. The worm gear 782 meshes with the worm wheel 783, thereby causing the hollow shaft 71 to rotate synchronously (the protective shell 781 protects the worm gear 782 and the worm wheel 783). Multiple sets of aluminum heat dissipation fins can be installed through the shell of 81 to release the heat generated by the meshing of the worm gear 782 and worm wheel 783 inside the shell 781 through heat transfer. The hollow shaft 71 drives the guide shell 74 to rotate synchronously around its hollow shaft through the lower half shell 73 (the upper half shell 72 is stationary due to its fixed connection with the feed pipe 77, and the upper inner arc wall of the upper half shell 72 is rotatably connected to the outer arc surface of the hollow shaft 71 through a sealed bearing). The rotation of the guide shell 74 enables the circular spreading and feeding of materials into the mixing shell 6. At the same time, the added enzyme preparation raw materials are stacked vertically layer by layer. By increasing the coverage and dispersion uniformity of the enzyme preparation raw materials in the mixing shell 6, the mixing efficiency of the granular enzyme preparation and carrier in the mixing shell 6 is improved. The device uses a transmission element to enable the enzyme preparation raw materials to be mixed and fed in a circular dispersion manner, thereby improving the mixing rate of the enzyme preparation raw materials.

[0027] like Figure 4As shown, the air blowing mechanism 8 is located between the frame 1, the material pipe 5, and the mixing shell 6. The air blowing mechanism 8 includes a connecting pipe 81, an air supply pipe 83, an air pump 84, and a breathable filter 85. The connecting pipe 81 is located between the upper ends of the two material pipes 5. The upper side of the frame 1 is provided with an air pump 84. The input end of the air pump 84 is electrically connected to the output end of the controller 2. The air outlet of the air pump 84 is connected to the middle part of the connecting pipe 81 through the air supply pipe 83. The top wall of the mixing shell 6 is provided with a breathable filter 85. The air blowing mechanism 8 also includes a solenoid valve 82. The solenoid valve 82 is connected in series to the upper end of the material pipe 5 and the left and right ends of the connecting pipe 81. The input ends of the solenoid valve 82 are all electrically connected to the output end of the controller 2.

[0028] After the enzyme preparation raw material is quantitatively fed, controller 2 closes the solenoid valve 82 on the screw weighing feeder 4 and the feed pipe 5, while simultaneously opening the solenoid valves 82 at both ends of the connecting pipe 81 (when quantitatively feeding the enzyme preparation raw material, controller 2 opens the solenoid valve 82 on the feed pipe 5 and closes the solenoid valves 82 at both ends of the connecting pipe 81 to prevent material from entering the connecting pipe 81). Then, controller 2 starts the air pump 84 to deliver high-pressure gas to the air supply pipe 83 (the air pump 84 consists of a compression unit and a power system). The system consists of a control module and a power system with an electric motor as its core. A piston is driven to reciprocate via a linkage mechanism or eccentric shaft, thereby compressing the gas in the compression unit and directing it into the air supply pipe 83. A dust filter is installed at the air inlet of the air pump 84 to filter impurities from the incoming gas (the dust filter needs to be removed and cleaned periodically). The high-pressure gas in the air supply pipe 83 travels along the connecting pipe 81 through the material pipe 5, the feed pipe 77, the cavity formed by the upper shell 72 and the lower shell 73, and the guide shell. 74 enters the mixing shell 6 through the channel 75, and high-pressure airflow flushes the conveying pipe, allowing the high-pressure airflow to carry the material remaining in the conveying pipe into the mixing shell 6. This prevents the decrease in the quantitative conveying accuracy of enzyme preparation raw materials due to material retention in the conveying pipe, and at the same time, it cleans the conveying pipe to prevent blockage. The high-pressure gas in the mixing shell 6 is discharged through the breathable filter 85 (the breathable filter 85 is fixed with screws and needs to be disassembled and cleaned regularly to prevent a decrease in its filtration efficiency; the gas filter in the device has a pore size of 0.2mm; the pipes in the device are connected and fixed to each other and to the solenoid valves through flanges, and the flange connection surfaces are sealed with embedded rubber sealing rings. The rubber sealing rings need to be replaced regularly to prevent aging). This device uses an air blowing element to feed the residual material in the conveying pipe, improving the mixing ratio accuracy of enzyme preparation raw materials while reducing the pipe conveying blockage rate.

[0029] like Figure 1-2As shown, a mixing shaft 9 is rotatably connected inside the hollow shaft 71 via a sealed bearing 3. A spiral stirring blade 10 is located at the lower end of the outer arc surface of the mixing shaft 9. A servo motor 2 11 is mounted on the upper side of the mixing shell 6 via a bracket. The input end of the servo motor 2 11 is electrically connected to the output end of the controller 2. The output shaft of the servo motor 2 11 is fixedly connected to the upper end of the mixing shaft 9. The controller 2 starts the servo motor 2 11, causing its output shaft to drive the spiral stirring blade 10 to rotate clockwise around its own axis via the mixing shaft 9. (The outer surface of the mixing shaft 9 is rotatably connected to the walls of the mixing shell 6 and the protective shell 781 via a sealed bearing 6. The outer surface of the mixing shaft 9 is rotatably connected to the bracket via a bearing 2. Both bearing 1 and bearing 2 in the device are double-row tapered roller bearings, which can simultaneously withstand radial and bidirectional axial loads.) It possesses high rigidity, high load-bearing capacity, and excellent operational stability. (The axial structural strength of the bearing connection is enhanced by using double-row tapered roller bearings.) During the rotation of the spiral stirring blade 10, the spiral stirring blade 10 lifts the granular enzyme preparation or carrier at the bottom of the mixing shell 6 from bottom to top along the spiral blade surface through its own spiral surface, allowing the granular enzyme preparation or carrier at the bottom to continuously move towards the top of the mixing shell 6. At the same time, the centrifugal force generated by the rotation of the spiral stirring blade 10 will discharge some of the enzyme preparation or carrier in the spiral cylindrical surface towards the inner diameter of the mixing shell 6, realizing the radial diffusion of the enzyme preparation or carrier, thereby realizing the mixing operation between the granular enzyme preparation and the carrier. During this process, the controller 2 can regulate the mixing time between the enzyme preparation and the carrier through its own timing element, and automatically shuts off the servo motor 11 after the time is reached.

[0030] like Figure 1-2 As shown, a solenoid valve 12 is installed through the middle of the bottom discharge pipe of the mixing shell 6. The input end of the solenoid valve 12 is electrically connected to the output end of the controller 2. After the enzyme preparation raw materials are quantitatively mixed, the controller 2 opens the solenoid valve 12 and discharges through the bottom discharge pipe of the mixing shell 6.

[0031] The working principle of the enzyme preparation raw material quantitative mixing integrated machine provided by the present invention is as follows: When the device is used to quantitatively mix enzyme preparations and carriers, the material in the storage hopper 3 enters the feed inlet of the screw weighing feeder 4 through the bottom feed port under its own gravity. The controller 2 starts the screw weighing feeder 4 to quantitatively convey the corresponding enzyme preparation or carrier. The granular enzyme preparation or carrier enters the cavity formed by the upper shell 72 and the lower shell 73 through the feed pipe 77 along the corresponding feed pipe 5. Then, the granular enzyme preparation or carrier is spread and falls into the mixing shell 6 through the through groove 75 at the bottom of the guide shell 74 along the guide shell 74. The bottom wall plane of the lower shell 73 is blocked by the conical seat 76, so that the bottom of the lower shell 73 is in the position of the bottom wall. In an inclined state, materials are prevented from entering the corresponding guide shell 74 along the conical slope, reducing the probability of material stacking on the bottom wall of the lower shell 73. Simultaneously, the controller 2 activates the servo motor 784, causing its output shaft to drive the worm gear 782 to rotate. The worm gear 782 meshes with the worm wheel 783, causing the hollow shaft 71 to rotate synchronously. The hollow shaft 71, through the lower shell 73, drives the guide shell 74 to rotate synchronously around its own hollow axis. The rotation of the guide shell 74 thus performs a circular spreading and feeding of materials into the mixing shell 6. Simultaneously, the added enzyme preparation raw materials are vertically layered, increasing the coverage and dispersion uniformity of the enzyme preparation raw materials during the feeding process within the mixing shell 6, thereby improving the mixing efficiency of the granular enzyme preparation and carrier within the mixing shell 6. During this process, controller 2 activates servo motor 11, causing its output shaft to drive the spiral stirring blade 10 to rotate clockwise around its own axis via mixing shaft 9. As the spiral stirring blade 10 rotates, it lifts the granular enzyme preparation or carrier from the bottom of the mixing shell 6 cone upwards along its spiral surface, allowing the granular enzyme preparation or carrier at the bottom to continuously move towards the top of the mixing shell 6 cone. Simultaneously, the centrifugal force generated by the rotation of the spiral stirring blade 10 discharges some of the enzyme preparation or carrier within the spiral cylindrical surface towards the inner diameter of the mixing shell 6 cone, achieving radial diffusion of the enzyme preparation or carrier, thereby realizing the mixing operation between the granular enzyme preparation and the carrier. During this process, controller 2 can use its own timing element to monitor the enzyme preparation and carrier... The mixing time between carriers is regulated, and the servo motor 11 automatically shuts off after the time is reached. After the enzyme preparation raw materials are quantitatively mixed, the controller 2 opens the solenoid valve 12, and the raw materials are discharged through the bottom outlet pipe of the mixing shell 6. After the enzyme preparation raw materials are quantitatively fed, the controller 2 closes the solenoid valve 82 on the screw weighing feeder 4 and the feed pipe 5, and simultaneously opens the solenoid valves 82 at both ends of the connecting pipe 81. Then, the controller 2 starts the air pump 84 to deliver high-pressure gas to the air supply pipe 83. The high-pressure gas in the air supply pipe 83 travels along the connecting pipe 81 through the feed pipe 5, the feed pipe 77, the cavity formed by the upper shell 72 and the lower shell 73, the guide shell 74, and through the through groove 75 into the mixing shell 6, thus flushing the conveying pipeline with high-pressure airflow.This allows the high-pressure airflow to carry the material remaining in the conveying pipe into the mixing shell 6, preventing a decrease in the quantitative conveying accuracy of the enzyme preparation raw materials due to material retention in the conveying pipe. Simultaneously, by cleaning the conveying pipe, blockages are prevented. The high-pressure gas inside the mixing shell 6 is discharged through the breathable filter 85.

[0032] It is worth noting that the controller 2 disclosed in the above embodiments can be 6ES7274-1XK30-0XA0, the screw weighing feeder 4 can be YB-LXC single-tube screw scale, the servo motor 784 can be 60ST-M00630LBX, the air pump 84 can be ML601-24 small high-pressure air pump, the solenoid valve 82 and the solenoid valve 12 can both be ZQDF-3Y-40, and the servo motor 11 can be Y90S-2. The controller 2 controls the operation of the screw weighing feeder 4, the servo motor 784, the air pump 84, the solenoid valve 82, the servo motor 11, and the solenoid valve 12 using methods commonly used in the prior art.
