Description

Technical Field

[0001] The utility model relates to the technical field of double-shaft spiral ribbon mixers, in particular to a double-shaft spiral ribbon mixer. Background Art

[0002] At present, mixing equipment is applicable to a wide range of industries and is widely used in chemical, pharmaceutical, food, dye, pigment, feed and cosmetic industries. The mixing equipment used in industrial production is mainly divided into two categories, one is fixed container type and the other is rotary container type. Horizontal ribbon mixers belong to fixed container mixing equipment, which are generally used for mixing viscous or cohesive powders and particles and adding liquids and paste materials to powders and particles. At the same time, due to the difficulty in cleaning viscous materials, they are suitable for mixing in occasions with large output and infrequent changes in varieties. Existing ribbon mixers are usually single-axis single-ribbon or single-axis double-ribbon, which have the disadvantages of long mixing time, dead corners during mixing, and easy agglomeration of materials when mixing powdered materials with liquid materials.

[0003] For example, the utility model with application number 202022430737.0 discloses a double-shaft ribbon mixer. The utility model provides a double-shaft ribbon mixer, which can greatly shorten the mixing time, improve the mixing efficiency, eliminate the mixing dead corners to the maximum extent, and effectively ensure the uniformity of material mixing.

[0004] Similar to the above application, there are still some deficiencies:

[0005] This type of twin-shaft ribbon mixer uses a twin-shaft ribbon to improve mixing efficiency, but does not pre-disperse and pre-mix the mixed materials. Directly pouring the required mixed materials into and mixing them will cause uneven distribution of different materials, resulting in slow mixing speed and low efficiency, and cannot meet production needs.

[0006] For this reason, a double-shaft ribbon mixer is designed to optimize the above problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a double-shaft ribbon mixer to solve the relevant technical problems raised in the above background technology.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0010] Preferably, a storage bin is fixedly installed on one side of the mixing bin, a screw feeder is installed inside the storage bin, and an outlet end of the screw feeder is higher than the height of the dispersion net.

[0012] Preferably, a support is provided at the bottom of the mixing bin, and a shock-absorbing pad is provided at the bottom of the support.

[0013] Preferably, a protective layer is provided at the bottom of the movable plate, and the protective layer is a wear-resistant protective layer.

[0014] Preferably, a sliding opening is provided at the connection between the mixing bin and the movable plate, and a sliding rod is fixed between the movable plate and the dispersion net.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a double-shaft ribbon mixer, which can evenly transport materials into the mixing bin for mixing through the coordinated use of a mixing bin, a mixing shaft, a first sprocket, a motor, a second sprocket, a chain, a first gear, a rotating shaft, a second gear, a cam, a fixing rod, a spring, a movable plate and a dispersion net. At the same time, the agglomerated materials are vibrated and dispersed, which is more conducive to the mixing between the materials, thereby improving the mixing efficiency of the double-shaft ribbon mixer.

[0017] By using the storage bin and the screw feeder in conjunction, the material is put into the storage bin, and the screw feeder drive power is started, so that the material inside the storage bin is transported upward and premixed by the screw feeder, and the material is transported to the dispersion net through the outlet of the screw feeder.

[0018] Through the coordinated use of the closed bin and the through port, the closed bin seals the top of the dispersion net to prevent the dust from flying outwards due to the up and down vibration of the material, which plays a good protective role. The through port facilitates the connection and installation of the discharge port of the spiral feeder, thereby meeting people's different usage needs. BRIEF DESCRIPTION OF THE DRAWINGS
