Description

Technical Field

[0001] The present invention relates to the field of chemical production equipment, and in particular to a bottom discharging structure of a sound resonance mixing container and a sound resonance mixing container. Background Art

[0002] In traditional sound resonance mixing containers, the side walls and the bottom are of an integral non-opening structure, and both the feeding and discharging methods are through top openings. The corresponding discharging method is to turn the container over for discharging. This discharging method requires lifting the mixing container and then tipping it over. However, the mixing container is heavy when full, and there is a risk of the pot body tipping over. The discharging efficiency is low, which is not conducive to the continuous flow of materials. At the same time, this discharging method relies on gravity to discharge the slurry, resulting in more slurry remaining on the inner wall of the container, causing waste. In addition, sound resonance mixing is achieved by driving the mixing container to vibrate with a certain amplitude at a high intensity, and the acceleration is as high as 100G. Traditional valve structures are difficult to withstand such high-intensity vibrations, easily leading to the failure of the valve structure and causing material overflow; traditional valve structures are relatively large in volume, occupying the limited internal space of the sound resonance mixer, reducing the loading capacity of the medicine. In order to improve the safety of the production process, reduce the residual slurry, and be suitable for sealing under low-frequency and high-acceleration vibrations, it is necessary to carry out targeted technological innovation on the device. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned deficiencies of the prior art, and to provide a bottom discharging structure of a sound resonance mixing container, which can adapt to the low-frequency and high-acceleration vibrations of the sound resonance mixing container and can significantly improve the transfer of materials, especially the transfer efficiency of highly viscous slurry.

[0010] A positioning stop is convexly provided upward on the outer periphery of the round hole in the middle of the discharge cover of the top-opening device, and the positioning stop is matched with the opening at the bottom of the acoustic resonance mixing container.

[0011] A groove is concaved at the top end of the discharge rod, and the groove is matched with the cylindrical body at the bottom of the plug. When the discharge rod pushes the plug upward until the positioning stop fits with the opening at the bottom of the acoustic resonance mixing container, the discharge rod of the top-opening device pushes the plug open, and the upper surface of the plug is flush with the inner cavity bottom surface of the acoustic resonance mixing container.

[0012] It further includes a hopper, and an annular groove is concaved on the upper end surface of the outer wall of the hopper; The diameter of the discharge cover is not less than that of the acoustic resonance mixing container, and a second sealing ring that can be matched and sealed with the annular groove on the hopper is embedded at the lower end of the discharge cover.

[0015] The beneficial effects are as follows:

[0016] 1.

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] In order to adapt to the overall low-frequency and high-acceleration vibration working conditions, it is not appropriate to use valves and other forms as sealing structures. Based on the above problems, the present invention proposes a sealing structure that can resist low-frequency and high-acceleration vibrations and a corresponding discharge structure to realize the discharge of the sealing machine.

[0024] like Figure 1-6As shown in the figure, the bottom discharging structure of the low-frequency high-acceleration vibration acoustic resonance mixing container includes a discharging port provided at the bottom of the acoustic resonance mixing container 1, a discharging port closing device, a jacking device 2, and a plunger 3. The hopper 4 is a material receiving device and is fixed on the next process equipment.

[0025] As Figure 2-3 As shown in the figure, the original bottom of the acoustic resonance mixing container 1 was a single-layer structure. In order to achieve bottom discharging, the acoustic resonance mixing container 1 was changed to a double-layer layout, and at the same time, a cone-shaped discharging port with a larger upper part and a smaller lower part was designed at the center of the bottom for discharging. A discharging port closing mechanism for closing the discharging port during material mixing is provided at the discharging port. The discharging port closing mechanism mainly consists of a plug 1-2, a sealing ring 1-3, a sealing plate 1-4, and a self-locking nut 1-5. The plug 1-2 is divided into two parts. The upper half is also a cone structure, and it has the same shape and angle as the discharging port. The height of the cone at the upper part of the plug 1-2 is less than the height of the discharging port. The cone at the upper end of the plug 1-2 is in a small clearance fit with the discharging port. A sealing ring 1-3 is nested around the cone part to make the plug 1-2 fit the bottom discharging port of the acoustic resonance mixing container 1 and fill the gap between the two. The lower half of the plug 1-2 is a cylindrical structure with external threads for the installation and fixation of the self-locking nut 5. The cone and the cylinder of the plug 1-2 are coaxially connected. The inner diameter of the sealing plate 1-4 is slightly larger than the outer diameter of the lower cylindrical part of the plug 1-2, and the outer diameter of the sealing plate 1-4 is the same as the bottom opening of the acoustic resonance mixing container 1 and can be embedded therein to prevent the leakage of the slurry. The self-locking nut 1-5 consists of a normal nut (right-handed) and a reverse nut (left-handed), and the two are used in combination to ensure that it does not loosen under low-frequency high-acceleration vibration.

[0026] As Figure 4-5As shown in the figure, the top-opening device 2 is used to open the plug 1-2 that removes the self-locking nut 1-5 and the sealing plate 1-4 after the mixing is completed, and discharge the mixed material from the discharge port. The top-opening device 2 mainly consists of a discharge cover 2-1, a sealing ring 2-2, a fixing strip 2-3, a discharge rod 2-4, a positioning stop 2-6, and a feed port 2-5 formed between the discharge cover 2-1 and the discharge rod 2-4. A through hole with an inner diameter not less than the bottom diameter of the upper cone of the plug 1-2 is provided in the middle of the discharge cover 2-1. The outer diameter of the discharge rod 2-4 is smaller than the bottom diameter of the upper cone of the plug 1-2. After the discharge rod 2-4 is vertically fixed to the discharge cover 2-1 by several fixing strips 2-3, its upper end is located at the center of the through hole. The gap between the outer wall of the discharge rod 2-4 and the round hole is the feed port 2-5 for the mixed material to pass through. The discharge cover 2-1, the fixing strip 2-3, and the discharge rod 2-4 are fixedly connected together by welding. One end of the fixing strip 2-3 is connected to the discharge cover, and the other end is connected to the discharge rod 2-4 to fix the discharge rod 2-4 relative to the discharge cover 2-1, and six or more are used to counteract the pressure transmitted from the plug 1-2 to the discharge rod 2-4 when the plunger 3 presses down the slurry. The sealing ring 2-2 is adhered to the back of the discharge cover. A semi-circular groove is designed at the corresponding position of the top of the hopper 4 and the sealing ring 2-2 to achieve the positioning of the discharge device 2 and the positioning seal between the discharge device 2 and the hopper 4. A positioning stop 2-6 protrudes upward from the outer periphery of the middle round hole of the discharge cover 2-1 of the top-opening device 2. The opening at the bottom of the acoustic resonance mixing container 1 is matched with the positioning stop 2-6 to achieve the positioning seal between the acoustic resonance mixing container 1 and the discharge device 2 and prevent slurry leakage during discharging. The outer diameter of the discharge cover 2-1 is the same as that of the hopper 4, and the diameter of the central through hole is not less than the inner diameter of the lower side of the discharge port of the acoustic resonance mixing container 1. There is a groove at the top end of the discharge rod 2-4. The diameter of this groove is slightly larger than the outer diameter of the lower cylinder of the plug 1-2, and the depth is designed so that when the discharge cover 2-1 fits with the acoustic resonance mixing container 1, the plug 1-2 is just lifted to make its upper end surface flush with the lower surface of the inner cavity of the acoustic resonance mixing container 1, maximizing the opening of the discharge port without affecting the pressing action of the plunger 3 and ensuring the least amount of slurry residue after extrusion. The discharge port of the acoustic resonance mixing pot is communicated with the feed port 2-5 of the discharge device 2, and cooperates with the plunger 3 to achieve bottom extrusion and discharging.

[0027] Usage process: As Figure 7-19As shown, when mixing in the low-frequency high-acceleration vibration stage, the plug 1-2 blocks the discharge port of the acoustic resonance mixing container 1. Subsequently, the sealing plate 1-4 and the self-locking nut 1-5 are installed in sequence to achieve fixation. At the same time, the conical structures of the discharge port and the upper part of the plug 1-2 can also ensure the sealing effect through the tightening degree of the self-locking nut 1-5. Through the above installation method and structural design, the technical problems of anti-low-frequency high-acceleration vibration and sealing faced by the acoustic resonance mixing container for bottom discharge can be solved. After mixing is completed, the discharging device 2 is placed on the hopper 4 and positioned by the sealing ring and the groove at the top of the hopper 4. Then, the self-locking nut 1-5 and the sealing plate 1-4 are removed by mechanical means (such as a robotic arm) or manually. Next, the acoustic resonance mixing pot 1 is transported above the hopper 4 (the operation process is not the focus of this application, and existing conventional means capable of completing this work can be used). The plug 1-2 is slowly lowered and aligned with the groove of the discharge rod 2-4, and is positioned by the bottom opening of the acoustic resonance mixing container 1 and the positioning stop 2-6. The plug 1-2 is lifted by the groove at the top of the discharge rod 2-4 until the upper surface of the plug 1-2 is flush with the lower surface of the inner cavity of the acoustic resonance mixing container 1, and the discharge port is communicated with the feed port 2-5, opening the channel for the slurry to flow into the hopper 4. Combined with the plunger 3, the slurry can be extruded into the hopper 4. The plunger 3 generates a squeezing effect on the slurry downward by mechanical means (existing equipment such as a press or a hydraulic cylinder that can achieve the downward pressure work) or manually, and slowly presses it into the hopper 4 through the channel, thereby realizing efficient and safe bottom discharge of the mixing container.
