Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to an automatic control type mixing device. Background Art

[0002] A mixer is a type of machine used to stir and mix materials. The mixer mixes materials by putting different materials into a tank and using the stirring rod inside to stir and mix the materials evenly.

[0003] Some materials may clump together due to factors such as humidity. If the clumped materials are directly put into the mixing tank, the clumped materials will easily pass through the gap between the two stirring rods due to the large gap between the stirring rods, and it is difficult to ensure that the clumped materials can be broken up. When the clumped materials are mixed, the density distribution in a local area of ​​a certain material will be large, which will lead to uneven mixing of the materials. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic control type mixing device with the function of breaking up the agglomerated materials, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] The invention discloses an automatic controlled mixing device, comprising a mixing tank, a conical discharge barrel and an axle rod. The conical discharge barrel is fixed in the mixing tank and is close to the top end of the mixing tank. The diameter of the conical discharge barrel becomes smaller as it goes down. The temporary storage part is located above the conical discharge barrel in the mixing tank, and the mixing part is located below the conical discharge barrel. The axle rod is arranged in the mixing tank, and the axle rod passes through the conical discharge barrel and extends vertically in the temporary storage part and the mixing part. A first annular discharge opening is formed between the lower end of the conical discharge barrel and the outer wall of the axle rod. A throwing plate is fixed on the axle rod below the conical discharge barrel, and a second annular discharge opening is formed between the outer edge wall of the throwing plate and the inner wall of the mixing tank. Stirring rods are evenly distributed on the axle rod below the throwing plate. A driving mechanism for driving the axle rod to rotate is provided at the top of the mixing tank, and a discharging mechanism for discharging the mixed material from the mixing tank is provided at the bottom of the mixing tank.

[0007] Furthermore, a horizontally extending connecting arm is fixed on the shaft at the same height as the first annular discharge port, and crushing pieces are fixed on the connecting arm at intervals along its length direction. The top end of each crushing piece extends into the conical discharge barrel, and the bottom end extends into the mixing part.

[0008] Furthermore, the driving mechanism includes a mounting seat and a first driving motor. The mounting seat is arranged on the top of the mixing tank. The first driving motor is fixed to the top of the mixing tank through the mounting seat. The top end of the shaft extends through the top of the mixing tank and is fixedly connected to the output shaft of the first driving motor.

[0009] Furthermore, the discharge mechanism includes a discharge barrel, an auger conveying rod and a second drive motor. The bottom end of the mixing tank is a cone shape that converges toward the middle. The discharge barrel is fixed on the bottom end of the mixing tank. The material guide port on the discharge barrel is connected to the bottom end of the mixing tank. One end of the discharge barrel is sealed and the other end has an opening. The auger conveying rod is rotatably installed in the discharge barrel. The second drive motor is fixed on one sealed end of the discharge barrel. The output shaft of the second drive motor extends into the discharge barrel and is fixedly connected to one end of the auger conveying rod.

[0010] Furthermore, a control module is provided on the outside of the mixing tank, and the control module includes a control box fixed on the outside of the mixing tank, a micro industrial computer installed on the control box, and a controller installed on the control box. The controller is electrically connected to the micro industrial computer, the first drive motor, and the second drive motor respectively.

[0011] Furthermore, a plurality of feed ports are arranged on the outer wall of the mixing tank and are located above the conical feed port in a circular array around the conical feed port. Each feed port is connected to the temporary storage part, and there are at least two feed ports.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0013] 1. The utility model drives the shaft to rotate through the driving mechanism, and then drives the throwing plate and the stirring rod to rotate synchronously. The material falling on the throwing plate rotates with the throwing plate. Under the action of centrifugal force, the throwing plate throws the material to the periphery until the material hits the inner wall of the mixing tank, which can disperse the agglomerated material and realize pre-crushing of the material before mixing, ensuring that the material can be mixed evenly.

[0014] 2. In the utility model, material agglomerates whose size is larger than the distance between the outer edge wall of the throwing plate and the inner wall of the mixing tank cannot pass through the second annular discharge opening normally and fall downward, and as the throwing plate continues to rotate, these larger agglomerates will be retained above the second annular discharge opening, and the subsequent material agglomerates thrown to the periphery by the throwing plate will collide with the retained large agglomerates, which can break up the large agglomerates and crush them until they can pass through the second annular discharge opening and fall downward, thereby having the effect of screening the volume of material agglomerates, avoiding some agglomerates that are not completely crushed from falling into the bottom for stirring, and further ensuring the uniformity of the mixing.

[0015] 3. When the size of the large-volume agglomerates that fall into the temporary storage part of the utility model is larger than the distance between the inner edge of the lower end of the conical discharge barrel and the outer wall of the shaft rod, the large-volume agglomerates will be retained above the first annular discharge port. When the shaft rod rotates, it can drive the connecting arm and the crushing piece to rotate synchronously, and then the rotating crushing piece can cut the large-volume agglomerates retained above the first annular discharge port into pieces, avoiding blocking the first annular discharge port and affecting the downward movement of the material.

[0023] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] See also Figure 1-Figure 4 The utility model provides an automatic control type mixing device, comprising a mixing tank 1, a conical material discharge barrel 2 and a shaft rod 3. The conical material discharge barrel 2 is fixed in the mixing tank 1 and close to the top of the mixing tank 1. The diameter of the conical material discharge barrel 2 decreases as it goes downward. The mixing tank 1 has a temporary storage part 11 located above the conical material discharge barrel 2, and a mixing part 12 located below the conical material discharge barrel 2. The shaft rod 3 is arranged in the mixing tank 1, and the shaft rod 3 passes through the conical material discharge barrel 2 and is vertically arranged in the temporary storage part 11 and the mixing part 12. A first annular discharge opening 21 is formed between the lower end of the conical discharge barrel 2 and the outer wall of the shaft rod 3, a material throwing tray 4 is fixed on the shaft rod 3 below the conical discharge barrel 2, a second annular discharge opening 41 is formed between the outer edge wall of the material throwing tray 4 and the inner wall of the mixing tank 1, stirring rods 31 are evenly distributed on the shaft rod 3 below the material throwing tray 4, a driving mechanism 5 for driving the shaft rod 3 to rotate is provided on the top of the mixing tank 1, and a discharging mechanism 6 for discharging the mixed material from the mixing tank 1 is provided at the bottom of the mixing tank 1.

[0025] When the materials are mixed by the automatic control mixing device, the materials are put into the temporary storage part 11. Due to the shape of the conical discharge barrel 2 which is larger at the top and smaller at the bottom, the materials automatically slide down along the inner wall of the conical discharge barrel 2 to the first annular discharge port 21, and fall onto the throwing plate 4 through the first annular discharge port 21. At the same time, the drive mechanism 5 drives the shaft 3 to rotate, and then drives the throwing plate 4 and the stirring rod 31 to rotate synchronously. The materials that fall on the throwing plate 4 rotate with the throwing plate 4. Under the action of centrifugal force, the throwing plate 4 throws the materials to the periphery until the materials hit the inner wall of the mixing tank 1, which can disperse the agglomerated materials and realize the pre-crushing of the materials before mixing, thereby ensuring that the materials can be mixed evenly.

[0026] The dispersed lumps of material are broken up into small-volume materials, and finally flow into the lower part of the mixing tank 1 through the second annular discharge port 41. At this time, the stirring rod 31 rotating with the shaft 3 can stir and mix the materials. After the stirring is completed, the mixed materials can be discharged from the bottom of the mixing tank 1 to the outside through the discharge mechanism 6, thereby completing the automatic mixing of the materials.

[0027] In addition, material agglomerates whose sizes are larger than the distance between the outer edge wall of the material throwing plate 4 and the inner wall of the mixing tank 1 cannot pass through the second annular discharge port 41 and fall downward normally. As the material throwing plate 4 continues to rotate, these larger agglomerates will be retained above the second annular discharge port 41, and the subsequent material agglomerates thrown out to the periphery by the material throwing plate 4 will collide with the retained large agglomerates, thereby breaking up the large agglomerates and crushing them until they can pass through the second annular discharge port 41 and fall downward, thereby having the effect of screening the volume of material agglomerates, avoiding some agglomerates that are not completely crushed from falling into the bottom for stirring, and further ensuring the uniformity of the mixing.

[0028] Specifically, a horizontally extending connecting arm 22 is fixed on the shaft 3 at the same height as the first annular discharge port 21, and crushing pieces 23 are fixed on the connecting arm 22 at intervals along its length direction. The top end of each crushing piece 23 extends into the conical discharge barrel 2, and the bottom end extends into the mixing section 12. When the size of the large-volume agglomerates falling into the temporary storage section 11 is larger than the distance between the inner edge of the lower end of the conical discharge barrel 2 and the outer wall of the shaft 3, the large-volume agglomerates will be retained above the first annular discharge port 21. When the shaft 3 rotates, it can drive the connecting arm 22 and the crushing pieces 23 to rotate synchronously, and then the rotating crushing pieces 23 can cut the large-volume agglomerates retained above the first annular discharge port 21 into pieces, thereby avoiding blocking the first annular discharge port 21 and affecting the downward movement of the materials.

[0029] Specifically, the driving mechanism 5 includes a mounting seat 51 and a first driving motor 52. The mounting seat 51 is arranged on the top of the mixing tank 1. The first driving motor 52 is fixed to the top of the mixing tank 1 through the mounting seat 51. The top end of the shaft rod 3 extends through and extends to the top of the mixing tank 1 and is fixedly connected to the output shaft of the first driving motor 52. When the first driving motor 52 works, its output shaft can drive the shaft rod 3 to rotate, thereby providing drive for the rotation of the shaft rod 3.

[0030] Specifically, the discharging mechanism 6 includes a discharging barrel 61, an auger conveying rod 62 and a second driving motor 63. The bottom end of the mixing tank 1 is a cone shape that converges toward the middle. The discharging barrel 61 is fixed on the bottom end of the mixing tank 1. The guide port 611 on the discharging barrel 61 is communicated with the bottom end of the mixing tank 1. One end of the discharging barrel 61 is sealed and the other end has an opening. The auger conveying rod 62 is rotatably installed in the discharging barrel 61. The second driving motor 63 is fixed on the sealed end of the discharging barrel 61. The output shaft of the second driving motor 63 extends into the discharging barrel 61 and is fixedly connected to one end of the auger conveying rod 62. The mixed material falls into the discharging barrel 61 through the guide port 611, and the auger conveying rod 62 is driven to rotate in the discharging barrel 61 by the second driving motor 63. Then, the rotating auger conveying rod 62 can spirally convey the material in the discharging barrel 61, and finally discharge it through the open end of the discharging barrel 61.

[0031] Specifically, a control module 7 is provided on the outside of the mixing tank 1. The control module 7 includes a control box 71 fixed on the outside of the mixing tank 1, a micro-industrial computer 72 installed on the control box 71, and a controller 73 installed on the control box 71. The controller 73 is electrically connected to the micro-industrial computer 72, the first drive motor 52, and the second drive motor 63, respectively. By inputting corresponding control commands on the micro-industrial computer 72, the micro-industrial computer 72 transmits the control signal to the controller 73, and the controller 73 controls the first drive motor 52 and the second drive motor 63 to perform corresponding work. In this way, the overall automatic control of the device can be realized, and manual intervention can be reduced during the mixing process. The degree of automation is high, and the labor intensity of the staff is reduced.

[0032] Specifically, there are several feed ports 101 on the outer wall of the mixing tank 1 and located above the conical discharge barrel 2 in a circular array around the conical discharge barrel 2. Each feed port 101 is connected to the temporary storage part 11. Various materials can be put into the mixing tank 1 through the feed port 101. There are at least two feed ports 101, thereby providing at least two delivery parts for simultaneous delivery of different materials.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
