Description

Technical Field

[0001] This utility model relates to a cone mixer, specifically a cone mixer with a material buffer structure, and belongs to the technical field of cone mixers. Background Technology

[0002] The cone mixer is a device used for mixing powder or granular materials. It has the advantages of high automation, good mixing effect, good sealing and wide adaptability, and is widely used in pharmaceutical, chemical and food industries.

[0003] According to patent CN218250052U, a square cone mixer is disclosed, which includes a left support base, a right support base, and a cone. The two ends of the left support base are movably installed with guide rails, and a storage box is fixedly connected between the guide rails. The right support base is fixedly connected to one side of the support plate, and a liquid storage box is fixedly installed inside the right support base.

[0004] The above-mentioned solutions, through various structural combinations, enable the device to achieve automatic metering and feeding, and facilitate quick cleaning of the cone. However, during implementation, it is inconvenient to buffer the material during discharge. When the mixed material is discharged vertically by gravity, it will be subjected to a large impact force, which can easily affect the density stability of the material. Furthermore, the device lacks environmental monitoring capabilities. If operators accidentally enter the operating range of the cone, their personal safety will be seriously threatened, posing a high risk. Therefore, we provide a cone mixer with a material buffering structure to solve the above problems. Utility Model Content

Detailed Implementation

[0022] This utility model embodiment provides a square cone mixer with a material buffer structure.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The mixture includes a cone mixer 1, which rotates under the drive of a drive device 5. This causes the internal materials to move in three-dimensional space within a sealed hopper, generating strong tumbling, diffusion, and contraction effects, thereby achieving a mixing effect. This method uses the principle of gravity diffusion for mixing, resulting in minimal pressure on the materials and avoiding shearing and pulverization. The structural components shown in the accompanying drawings are illustrative examples. The specific implementation should be adapted and optimized based on the functional requirements, assembly conditions, and process limitations of the actual application scenario, adjusting the structural parameters, dimensions, and connection methods accordingly.

[0024] The top of the cone mixer 1 is fixedly equipped with a breather filter 10 and a vacuum feed port 11. The breather filter 10 contains a filter medium such as filter paper, filter cloth or filter screen, which can block pollutants such as particulate matter, bacteria, and viruses, while allowing air or gas to pass through, maintaining the internal pressure balance of the cone mixer 1, preventing cross-contamination, and ensuring the purity and quality of the mixed materials.

[0025] The vacuum feed port 11 is connected to an external vacuum generator via an air pipe. The vacuum feed port 11 utilizes the vacuum generator to draw in compressed air, creating a vacuum inside the cone mixer 1. This generates an airflow in the feeder, which conveys the material into the vacuum hopper. After a period of time, the vacuum disappears, and the material leaves the feeder and enters the receiving equipment, thus completing the entire transfer process. The vacuum feed port 11 offers advantages such as improved production efficiency, guaranteed product quality, adaptability to various materials, reduced energy consumption, and enhanced safety.

[0026] A cleaning ball 12 is fixedly installed at the top of the cone mixer 1. A solenoid valve is fixedly installed inside the cleaning ball 12. A rubber water pipe is fixedly installed at the end of the cleaning ball 12. The end of the rubber water pipe is connected to an external water pump. The cleaning ball 12 is a 5-inch quick-install 304 model. Its rotating ball head is located in a specific position inside the cone mixer 1. The principle is to use a water pump to deliver water and brake to achieve automatic rotation spraying and 360-degree rotation spray cleaning. The water pump delivers water to the cleaning ball 12 to provide power, enabling it to rotate automatically and spray the inner wall of the cone mixer 1 in all directions. This greatly reduces the workload of the staff cleaning the cone mixer 1 and improves the convenience and efficiency of cleaning.

[0027] The top of the cone mixer 1 is threaded with a quick-connect feed port 13, which serves to seal the cone mixer 1. Operators can open the cone mixer 1 by unscrewing the quick-connect feed port 13 from the top of the cone mixer 1 and connect other feeding equipment to the cone mixer 1, thereby realizing the rapid feeding operation of the cone mixer 1. The quick-connect feed port 13 and the cone mixer 1 have good sealing performance, which can effectively prevent material leakage and facilitate subsequent cleaning and maintenance of the inside of the cone mixer 1.

[0028] Please see Figure 1 , Figure 2 and Figure 4 The square cone mixer 1 is equipped with a frame 2 on its exterior. A ladder 14 is fixedly installed on the outer surface of the frame 2. The ladder 14 includes metal steps and guardrails for protection. The ladder 14 facilitates the cleaning, maintenance or inspection of the equipment by the staff. The surfaces of the steps and guardrails are treated with anti-slip material, which can effectively prevent the operator from slipping or falling during the climbing process and improve the safety of operation.

[0029] The printer 15 is fixedly installed inside the rack 2. The printer 15 is mainly used to record and print key data in the mixing process. It will automatically print out the complete data of the batch mixing at the end of the mixing process, so that the operator can monitor and verify whether the mixing process meets the preset standards and specifications. If any abnormality is found, the problem can be quickly found by checking the printed data and corresponding measures can be taken to make adjustments.

[0030] An emergency stop button 16 is fixedly installed on the outer surface of the frame 2. An indicator light 17 and an alarm 18 are also fixedly installed on the outer surface of the frame 2. The electrical control device 6 is electrically connected to each electrical component via cables. When an abnormal situation occurs during the operation of the device, the operator can press the emergency stop button 16 to stop the operation of the device. The indicator light 17 is used to indicate the operating status of the equipment. A green light indicates normal operation, and a red light indicates a fault. The alarm 18 can emit a buzzing sound when the equipment malfunctions, to warn the operator and remind them to stop the equipment in time to minimize the damage to the equipment.

[0031] The drive unit 5 is fixedly installed inside the frame 2. The drive unit 5 includes a motor for driving the square cone mixer 1, a reducer for adjusting the speed, a rolling bearing connecting the support rod 4 and the motor, a double-row sprocket for transmission connection and a matching chain. The motor is a 7.5kW model, the reducer is a WPA175 model with a reduction ratio of 50:1, the rolling bearing is a 22222CA / W33 model, and the double-row sprocket chain is a 1.2-inch specification with one set of 38 teeth and one set of 19 teeth. It can stably drive the square cone mixer 1 to rotate and improve the drive stability of the device.

[0032] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The internal structure of the frame 2 is equipped with an electrical control device 6, which includes a touch screen (model 6AV6648-0CC11-3AX0) for easy operation and observation by staff, a PLC controller (model 6ES7288-1SR20-0AA0) for controlling the operating parameters of various electrical equipment, a communication module (6ES7288-5CM01-0AA0), a circuit breaker (DZ47-4P32A), a frequency converter (7.5 kWHZ), and a relay (HHP54), etc. This device enables the various electrical components to automatically perform mixed operations according to the set program, thereby improving the automation level of the device. All electrical components involved in this application are existing technologies and will not be described in detail in this application.

[0033] A rotating frame 3 is fixedly connected to the outer surface of the square cone mixer 1. Two support rods 4 are fixedly connected to the outer surface of the rotating frame 3. Each support rod 4 is rotatably connected to the frame 2. The support rods 4 can drive the rotating frame 3 to rotate under the drive of the drive device 5, thereby causing the square cone mixer 1 to rotate at a certain frequency, so that the mixed materials inside the square cone mixer 1 can be effectively mixed.

[0034] The bottom of the cone mixer 1 is fixedly connected to a buffer pipe 7. An electric butterfly valve 8 is fixedly installed inside the buffer pipe 7. The buffer pipe 7 includes multiple straight pipes and inclined pipes at a certain angle. When the material is discharged through the cone mixer 1, the inclined pipe can buffer the falling material, thereby reducing the falling speed of the material and reducing the impact force it receives. This avoids the problem of unstable material density, ensures the filling accuracy of the filling machine, reduces the proportion of unqualified products, and improves product quality. The electric butterfly valve 8 adopts the DN204 model and can control the opening and closing of the buffer pipe 7.

[0035] Please refer to it again. Figure 1 , Figure 2 and Figure 4 Two far-infrared monitoring probes 9 are fixedly installed on the outer surface of the frame 2. The far-infrared monitoring probes 9 are SL08 models, which have the function of transmitting and receiving wireless signals and can monitor the device within a certain range. When the operator enters the monitoring range, the far-infrared monitoring probes 9 detect the presence of the operator and transmit a stop signal to the electronic control device 6. The electronic control device 6 receives the signal and controls the device to stop. After the operator leaves, the far-infrared monitoring probes 9 send a start signal to the electronic control device 6 again. At this time, the electronic control device 6 controls the device to start again.

[0036] Working principle: In use, the operating parameters of each electrical component of the device are first set through the electronic control device 6. Then, the device is controlled to operate. When the vacuum feed port 11 is activated, compressed air is drawn in by the vacuum generator, creating a vacuum inside the cone mixer 1. This generates an airflow in the feeder, which conveys the material to the vacuum hopper. After the conveying is completed, the drive device 5 is activated. The motor drives the cone mixer 1 to rotate within a certain range in the frame 2 through the transmission structure. The material inside the cone mixer 1 moves in three-dimensional space in the sealed hopper, generating strong tumbling and diffusion-contraction effects, thus achieving a mixing effect. After mixing is completed, the electric butterfly valve 8 controls the buffer pipe 7 to open. At this time, the material in the cone mixer 1 will be discharged through the buffer pipe 7. The buffer pipe 7 can buffer the falling material through the setting of straight and inclined pipes, thereby reducing the impact force and avoiding the problem of unstable material density.
