Abstract
Description
Technical Field
[0001] The invention relates to a mixing technology for small particles and powdery materials, and in particular to a novel high-efficiency horizontal cylindrical mixer. Background Art
[0002] As we all know, in feed, food, pharmaceutical, mining and other industries, ingredient mixing processes are involved. At present, the commonly used spiral ribbon mixer has the following problems during use: 1. There is only one feed port. When multiple ingredients are mixed, the feed speed is slow due to the small number of feed ports; 2. The main working part of the spiral ribbon mixer is the spiral ribbon on the stirring shaft, which stirs and turns the materials, and the mixing function is single; 3. Since the barrel of the spiral ribbon mixer is stationary, there will be residual materials at the bottom of the barrel and they cannot be effectively mixed, which affects the mixing uniformity; 4. The discharge port of the spiral ribbon mixer is generally located in the middle of the barrel. The small discharge port affects the discharge speed, the discharge time is long, and the discharge is not clear and there is residue; 5. There are generally long mixing cycles and low mixing uniformity. Summary of the invention
[0003] The purpose of the present invention is to design a novel high-efficiency cylindrical horizontal mixer, which can perform comprehensive actions such as rolling, dropping, diffusion, convection, tumbling, stirring, sliding, dropping, shearing, etc. on materials, achieve multi-dimensional mixing, and improve mixing uniformity.
[0004] The technical solution of the present invention is: a new type of high-efficiency horizontal cylinder mixer, which includes a mixing mechanism, a door opening and closing mechanism, and a cylinder limiting mechanism installed on a frame. A box is installed on the frame, the mixing mechanism is installed horizontally in the box, the door opening and closing mechanism is installed on the mixing mechanism, one or more feed hoppers are installed on the box above the mixing mechanism, a receiving hopper is installed on the frame below the mixing mechanism, and the cylinder limiting mechanism is installed on the shaft and the box of the mixing mechanism.
[0005] A further design is to install multiple feed hoppers in parallel on the box body above the mixing mechanism, with the large feed hopper installed in the middle and the small feed hoppers installed on both sides of the large feed hopper.
[0006] A further design is that the mixing mechanism includes: a cylinder, a rice-shaped support rod, an inner spiral guide blade, a push strip blade, and an axis; a long material door is opened horizontally on the cylinder wall; the cylinder is horizontally installed in a box on the frame through the axis, the rice-shaped support rod is arranged and installed on the axis inside the cylinder, the inner spiral guide blade is installed on the top of the rice-shaped support rod in a positive spiral direction, and the strip-shaped push strip blade is reversely installed on the rice-shaped support rod on the inner side of the inner spiral guide blade.
[0007] A further design is that the front and rear push strip blades are installed on the M-shaped support rod at a certain inclination angle to the axial direction, the inclination angle is opposite to the helical angle of the inner spiral guide blade, the inclination angle is equivalent to the helical angle of the guide blade, and there is a certain axial spacing between the axial push strip blades.
[0008] A further design is that a door opening and closing mechanism is respectively installed on the side walls at both ends of the cylinder, and the door opening and closing mechanism includes a cylinder, a slide rail, a slider and a connecting rod. The slide rail is installed on the end side wall of the cylinder, and the slider is installed on the slide rail. The piston rod of the cylinder installed on the side wall of the cylinder is connected to the slider, one end of the two connecting rods is respectively connected to the slider, and the other end of the two connecting rods is respectively connected to a material door. Under the action of the cylinder, the slider drives the connecting rod to open and close the material door.
[0009] A further design is that the cylinder limiting mechanism includes a limiting gear, a limiting cylinder, and an L-shaped thrust rod. The limiting gear is provided with a feed limiting convex tooth and a discharge limiting convex tooth. The limiting gear is installed on the axis of the cylinder. Two limiting cylinders and two L-shaped thrust rods are installed on the box body. The limiting cylinder drives the L-shaped thrust rod to respectively lock the feed limiting convex tooth and the discharge limiting convex tooth of the limiting gear, and controls the material door of the cylinder to be opened for feeding when it is in the highest position, and to be opened for discharging when it is in the lowest position.
[0010] The working process and principle of the present invention are as follows: when the cylinder limiting mechanism controls the material door of the cylinder to rotate to the highest position, the door opening and closing mechanism works to open the material door, the main raw material enters the cylinder from the middle large feed hopper, and other ingredients enter the cylinder from the small feed hoppers respectively. After the feeding is completed, the door opening and closing mechanism works to close the material door; the mixing mechanism works, and as the cylinder rotates, the material rolls and slides in the cylinder, and the material at the bottom of the cylinder is brought to a certain height and then thrown down and diffused. At the same time, the lower layer of material at the bottom of the cylinder is forwardly pushed, turned and stirred along the bottom under the action of the inner spiral guide blades, and the upper layer of material is stirred in the pushing strip. The impellers push the material in the opposite direction to cause the material to turn over and stir, and the upper and lower materials are mixed by convection. Since there is a certain distance between the axial forward and backward pushing strip impellers, the material slides up and down, falls, is sheared and diffused at the discontinuity. The material is mixed in multiple dimensions under the combined effects of rolling, dropping, diffusion, convection, turning, stirring, sliding, falling and shearing. After the mixing is completed, the cylinder limit mechanism controls the cylinder material door to rotate to the lowest position, and the door opening and closing mechanism works to open the material door, and the mixed material enters the receiving hopper and is discharged from the outlet. At this point, a mixing process ends, and then enters the next mixing cycle.
[0011] The advantages of the present invention are: 1. Under the action of the rotation of the cylinder, the positive push of the inner spiral guide blade and the reverse push of the push strip blade, the mixing mechanism plays a mixing role, which can realize the comprehensive effects of material rolling, throwing, diffusion, convection, tumbling, stirring, sliding, falling and shearing, and multi-dimensional mixing occurs. The materials are fully mixed, the mixing time is short, and the mixing uniformity is high.
[0012] 2. The door opening and closing mechanism allows for simultaneous feeding of multiple materials. The door opens wide during feeding and unloading, resulting in fast feeding and unloading speed and short time.
[0013] 3. The cylinder limit mechanism controls the position of the cylinder. When feeding, the material door is limited to the uppermost position, and when discharging, the material door is limited to the lowermost position. In fact, the same material door is used for feeding and discharging. The feeding and discharging are carried out along the entire length of the cylinder, and the feeding and discharging are fast.
[0014] 4. The drum rolls, the material rolls with the drum, there is no material residue at the bottom, and the mixing uniformity is high.
[0015] 5. A long material door with a horizontal opening is opened on the wall of the cylinder. The material door is long, the opening is large, the material discharge is fast, the material discharge is clear, and there is no residue.
[0016] 6. The new high-efficiency cylindrical horizontal mixer has a short mixing cycle, no residue after mixing and discharging, and a small coefficient of variation of mixing uniformity. It can be used to evenly mix various small particles and powdery materials, especially suitable for mixing various ingredients in feed factories to improve product quality and output.

One or more feed hoppers 7 are installed on the box 5 above the mixing mechanism 2, and a receiving hopper 8 is installed on the frame 1 below the mixing mechanism 2. The cylinder limiting mechanism 4 is installed on the shaft 6 of the mixing mechanism 2 and the box 5.
[0020] A further design is that a plurality of feed hoppers 7 are installed in parallel on the box body 5 above the mixing mechanism 2, with a large feed hopper installed in the middle and small feed hoppers installed on both sides of the large feed hopper.
[0021] like Figure 3 , 4 As shown, the mixing mechanism 2 includes: a cylinder 11, a rice-shaped support rod 12, an inner spiral guide blade 13, a push strip blade 14, and an axis 6; a long material door 15 is opened on the wall of the cylinder 11; the cylinder 11 is horizontally installed in a box 5 on the frame 1 through the axis 6, and the rice-shaped support rod 12 is arranged and installed on the axis in the cylinder 11, and the inner spiral guide blade 13 is installed at the top of the rice-shaped support rod 12 in a positive spiral direction, and the strip plate-shaped push strip blade 14 is reversely installed on the rice-shaped support rod 12 on the inner side of the inner spiral guide blade.
[0022] A further design is that the front and rear push strip blades 14 are installed on the rice-shaped support rod 12 at a certain inclination angle to the axial direction, the inclination angle is opposite to the helical angle of the inner spiral guide blade, the inclination angle is equivalent to the helical angle of the guide blade, and there is a certain distance between the push strip blades in the axial direction.
[0023] like Figure 5 , 6As shown, a switch door mechanism 3 is respectively installed on the side walls of the cylinder 11 at both ends, and the switch door mechanism includes a cylinder 16, a slide rail 17, a slider 18 and a connecting rod 19. The slide rail 17 is installed on the end side wall of the cylinder 11, and the slider 18 is installed on the slide rail 17. The piston rod of the cylinder 16 installed on the side wall of the cylinder 11 is connected to the slider 18, one end of the two connecting rods 19 is respectively connected to the slider 18, and the other end of the two connecting rods 19 is respectively connected to a material door 15. Under the action of the cylinder 16, the slider 18 drives the connecting rod 19 to open or close the material door 15.
[0024] like Figure 7 , 8 As shown in Figures 9 and 10, the cylinder limiting mechanism 4 includes a limiting gear 20, a limiting cylinder 21, and an L-shaped thrust rod 22. The limiting gear 20 is provided with a feed limiting convex tooth 23 and a discharge limiting convex tooth 24. The limiting gear 20 is mounted on the shaft 6 of the cylinder 11. Two limiting cylinders 21 and two L-shaped thrust rods 22 are mounted on the box body 5. The limiting cylinder 21 drives the L-shaped thrust rod 22 to respectively lock the feed limiting convex tooth 23 and the discharge limiting convex tooth 24 of the limiting gear 20, and controls the material door 15 of the cylinder 11 to be opened for feeding when it is at the highest position, and to be opened for discharging when it is at the lowest position.
