Description

Axial tension formula spiral continuous countercurrent leaching device

Technical field:

The axial tension formula spiral leached the utility model relates to a kind of pair of effective components from natural materials is continuously inverse Leaching device is flowed, natural products (such as Chinese medicine) extractive technique field is belonged to.

Background technique:

Spiral continuous countercurrent leaching device, material and solvent reverse flow because of its long stroke are constantly created and are kept Maximum concentration difference, forms the powerful motive force of effective component mass transfer diffusion in leaching process, thus becomes scale and leach work In skill improve leach yield and leach quality, it is energy-saving, reduce some effective of operating cost, increasingly by natural drug, The extensive favor of the enterprises such as health care product.

Spiral continuous countercurrent leaching device, it is in fact similar with screw conveyor, difference first is that whether there is or not the solvents in adverse current Middle conveying granular material, conveying principle are substantially consistent.Screw conveyor is all to be arranged in driving mechanism and discharge port The same end, feeding machanism are arranged in the other end.Because material is pushed to the other end from one end by helical blade, material is to helical blade One contrary axial thrust, this arrangement is scientific and reasonable, and axis can be made to be in tension state, not flexible.But existing skill The spiral continuous countercurrent leaching device of art is all that driving mechanism and feed inlet are arranged in the same end.As number of patent application is The prior art of entitled " the tube and tank type continuous countercurrent leaching device " of 201721315733.X, is by driving mechanism and inlet Setting belongs to axial compressive force formula spiral counterflow leaching device in the same end, in this way, just make that helical axis receives is axial compressive force.Although Every meter of shaft power is smaller, but spiral continuous countercurrent leaching device is all very long, and even up to 40 meters or more, axial compressive force accumulation will It is very big, if meeting the emergency cases such as blocking, helical axis can also be made to bend, or even fracture and damage equipment.Obviously, the prior art It is not scientific unreasonable that the same end, which is arranged in, in driving mechanism and feed inlet.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art, exist using by driving mechanism with cinder notch setting is unloaded The same end, providing one kind makes helical axis not by axial compressive force, the reasonable axial tension formula spiral continuous flow upstream of scientific structure design Leaching device.The technical solution of the utility model is: it includes with loader, bucket elevator slag-discharging device, inlet, goes out liquid Mouth, lid or hand hole, by the several sections of interior conveyor screws for having through-hole helical blade, the external leaching with heat exchange collet or ultrasonic wave component Body out is concatenated with flange head and the tail, its main feature is that: driving mechanism is arranged with bucket elevator slag-discharging device and inlet same One end, and loader and liquid outlet are arranged in the other end, the pedestal circular arc bottom outer rim and leaching machine of the bucket elevator slag-discharging device Circular arc bottom outer rim kiss in body slag dumping end connects and communicates, and constitutes two Room and communicates the deslagging assembly being integrated, arranges in the deslagging assembly The dress slag winnowing pan of the slag that slag conveyor screw is released and bucket elevator slag-discharging device head-on meets, and reverse slag input, deslagging assembly passes through Flange is connect with body is leached, the connection and leaching of helicoid shaft shaft end in the deslagging helicoid shaft and leaching machine body of deslagging assembly Make the connection of the helicoid shaft shaft end of hanging brace head and the tail concatenation in body by mid-mounting bearing out, torque and axis can be transmitted by being all made of To the coupling structure for the axis and set with radial through-hole of pulling force fastened with pin or screw.

Driving mechanism and inlet are arranged in the same end, spiral for the spiral continuous countercurrent leaching device of the prior art Body axis is by the not scientific irrational mix drawback such as axial compressive force, after the utility model, due to driving mechanism and slag-drip opening In the same end, this is a kind of helicoid shaft not scientific and reasonable arrangement by axial compressive force and by axial tension for setting, thus can Guaranteeing that helicoid shaft does not bend, when the higher thermal material of delivery temperature, the expansion of axis will not also influence driving mechanism work, It avoids equipment impaired, be conducive to keep the safety in production and extend equipment life；Bucket elevator slag-discharging device pedestal circular arc bottom outer rim and leaching Circular arc bottom outer rim kiss in body slag dumping end connects and communicates out, constitutes two Room and communicates the deslagging assembly being integrated, the deslagging assembly The dress slag winnowing pan of slag and bucket elevator slag-discharging device that middle deslagging conveyor screw is released head-on meets, formation effect it is best it is reverse into Slag keeps deslagging more smooth, avoids blocking, improves the allomeric function of leaching device.
