Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixer with high stability. Background Technology

[0002] A mixer is a mechanical device that mixes materials using mechanical rotation and gravity to uniformly mix them. It is widely used in various fields. As people's requirements for production efficiency continue to increase, mixers also need to have characteristics such as high efficiency and stability.

[0003] For example, Chinese invention patent document, publication number CN106268454A, provides a mixer comprising a vertically arranged cylinder and a stirrer. The stirrer includes a central shaft, a helical ribbon, and several support rods. The central shaft is arranged along the central axis of the cylinder and can rotate relative to the cylinder. The helical ribbon is fixed to the central shaft by the support rods, and the pitch and width of the helical ribbon gradually increase from bottom to top. The mixer of this invention provides rapid and effective mixing. The overall design of the equipment avoids cleaning dead zones such as sharp corners and bends. The stirring components are simple and effective, easy to clean, and have no mixing dead zones. It is suitable for the food and pharmaceutical industries, which require frequent cleaning, high hygiene, and high mixing uniformity. During operation, the stirring components spirally lift the material from bottom to top and then fall back from the center to create a strong convection mixing effect. Combined with the action of high-speed crushing blades, it can quickly achieve a uniform mixing effect.

[0004] The mixer described in the above document achieves mixing through an internal spiral ribbon and several support rods. The interior of the cylinder has no dead corners or sharp corners, making it suitable for fields with high hygiene requirements. However, the mixer in the above document still has many components inside the cylinder, resulting in a single force on the material being mixed. It is difficult to disperse quickly after the same material aggregates, especially when mixing two or more materials with different masses. Therefore, the mixing stability is poor. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a highly stable mixer that can use airflow to enhance the mobility of materials for further agitation. The spiral stirring plate inside the rotating drum can work with the auxiliary mixing mechanism to perform stable mixing, avoiding the agglomeration of single materials and improving the stability of the mixing.

[0006] The technical solution adopted by this utility model is as follows: It includes a mixing cylinder with a conical bottom and an outlet at the center of the bottom. An inlet is located on the upper surface of the mixing cylinder. A rotating cylinder is rotatably connected to the top center of the mixing cylinder. A spiral stirring plate is fixed to the outer wall of the rotating cylinder. A one-way device is provided on the bottom outer wall of the rotating cylinder.

[0008] Preferably, in order to facilitate the movement of materials inside the mixing drum, the bottom radius of the spiral stirring plate is smaller than the top radius, the rotation radius of the spiral stirring plate changes accordingly with the inner wall of the mixing drum, and a distance is left between the edge of the spiral stirring plate and the auxiliary mixing mechanism.

[0009] Preferably, in order to facilitate the flow of air into the mixing cylinder and prevent the material from flowing back into the rotating cylinder, the one-way device includes a limiting shell fixed to the outer wall of the bottom of the rotating cylinder. One side of the limiting shell is provided with a one-way opening. A moving block is slidably engaged in the one-way opening. A flow guide notch is engaged on the moving block. A contraction spring is fixedly connected between the side wall of the moving block and the outer wall of the rotating cylinder.

[0013] Preferably, in order to drive the annular disk to rotate more stably, the annular disk is driven to rotate by a drive motor. The bottom of the annular disk is fixed with a drive ring block with teeth on the inner wall. The drive motor is fixed on the upper surface of the mixing cylinder. The output shaft of the drive motor extends into the mixing cylinder and meshes with the inner wall of the drive ring block through a drive gear.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-8 As shown, this embodiment provides a highly stable mixer, including a mixing cylinder 1. The bottom of the mixing cylinder 1 is conical, and an outlet 101 is provided at the center of the bottom. An inlet 102 is provided on the upper surface of the mixing cylinder 1. A rotating cylinder 2 is rotatably connected to the top center of the mixing cylinder 1. A spiral stirring plate 201 is fixed on the outer wall of the rotating cylinder 2. A one-way device 3 is provided on the bottom outer wall of the rotating cylinder 2. A gas pipe 4 passes through the rotating cylinder 2. The gas pipe 4 needs to be connected to an external high-pressure gas source. The top end of the gas pipe 4 extends upward to the outside of the mixing cylinder 1. A spiral drive plate 202 with its edge close to the outer wall of the gas pipe 4 is fixed on the inner wall of the rotating cylinder 2. The spiral drive plate 202 can drive the rotating cylinder 2 to rotate under the push of the airflow. Preferably, a double spiral structure is adopted. A vent hole is provided on the outer wall of the gas pipe 4. The vent hole is located on one side of the upper part of the rotating cylinder 2. An auxiliary mixing mechanism 5 is provided inside the mixing cylinder 1. The auxiliary mixing mechanism 5 is used to perform circumferential stirring next to the inner wall of the mixing cylinder 1, thereby mixing the materials. A retaining plate 203 extending outward is fixed on the top outer wall of the rotating cylinder 2. A fixed bottom shell for rotating and limiting the retaining plate 203 is fixed on the top of the mixing cylinder 1. This makes it easy to fix the position of the rotating cylinder 2. The bottom radius of the spiral stirring plate 201 is smaller than the top radius. The rotation radius of the spiral stirring plate 201 changes accordingly with the inner wall of the mixing cylinder 1. A distance is left between the edge of the spiral stirring plate 201 and the auxiliary mixing mechanism 5. This makes it easy to move the materials inside the mixing cylinder 1.

[0026] The one-way device 3 includes a limiting housing 301 fixed to the bottom outer wall of the rotating cylinder 2. One side of the limiting housing 301 is provided with a one-way opening. A moving block 302 is slidably engaged in the one-way opening. A flow guide notch is engaged on the moving block 302. A contraction spring 303 is fixedly connected between the side wall of the moving block 302 and the outer wall of the rotating cylinder 2. An exhaust hole is opened on the outer wall of the rotating cylinder 2 on one side of the limiting housing 301. This facilitates the flow of air into the mixing cylinder 1 and prevents the material from entering the rotating cylinder 2 in the reverse direction.

[0027] The bottom end of the gas pipe 4 extends through the rotating cylinder 2 to the top of the outlet 101. The bottom end of the gas pipe 4 is slidably engaged with a blocking mechanism 6, which makes it easier to control the material discharge. The blocking mechanism 6 includes a sliding rod 601. A sliding groove is opened at the bottom of the gas pipe 4. A blocking spring 602 is fixedly connected to the top of the sliding rod 601 and the top of the sliding groove. A blocking block 603 is fixed at the bottom of the sliding rod 601. The top of the sliding groove is connected to the inside of the gas pipe 4 through a gas channel, which makes it easy to trigger and control the movement and reset of the blocking block 603.

[0028] When mixing materials, gas is first introduced into the gas pipe 4, which pushes the sliding rod 601 to move and push the blocking block 603 above the outlet 101 to seal the mixing cylinder 1. Then, the material is put in, and atmospheric pressure is applied to push the moving block 302 on the one-way device 3 to move. The moving block 302 extends into the limiting housing 301 until the guide gap leaks out. At this time, the gas can enter the mixing cylinder 1 and lift the material, making it easier to stir during mixing.

[0029] The auxiliary mixing mechanism 5 includes an annular disk 501 rotatably engaged with the top of the mixing cylinder 1. A stirring vertical plate 502 is fixed to the bottom of the annular disk 501. A power connector is provided on one side of the mixing cylinder 1 via a power cord, which enables more stable mixing of materials. The annular disk 501 is driven to rotate by a drive motor 503. A drive ring block with teeth on its inner wall is fixed to the bottom of the annular disk 501. The drive motor 503 is fixed to the upper surface of the mixing cylinder 1. The output shaft of the drive motor 503 extends into the mixing cylinder 1 and meshes with the inner wall of the drive ring block through a drive gear. Preferably, a pair of drive motors 503 are used to symmetrically drive the annular disk 501, which enables more stable rotation of the annular disk 501. The auxiliary mixing mechanism 5 is used to assist in mixing and stirring materials, thereby improving the mixing stability of materials.

[0030] This mixer can uniformly mix materials, using airflow to enhance material mobility for further agitation. The spiral stirring plate 201 inside the rotating drum 2 works in conjunction with the auxiliary mixing mechanism 5 to achieve stable mixing, preventing the aggregation of single materials and improving mixing stability. Furthermore, during mixing, the mixer can use high-pressure gas in the gas pipe 4 to drive the blocking mechanism 6, thereby controlling the opening and closing of the outlet 101 and preventing additional components from affecting the smooth discharge of materials.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
