In the drying process of aluminium fluoride ointment, spiral conveying device is needed to cooperate.

[0003] The prior art spiral conveyor in conveying aluminium fluoride ointment, in view of the ointment attached water content is about 20% or so. Spiral extends into the feed cover and drying kiln part directly with high temperature tail gas direct contact, aluminium fluoride ointment is extruded by spiral blade in the conveying process, and the inner wall of spiral is baked by high temperature flue gas, leading to aluminium fluoride ointment crusting and adhering on the inner wall of spiral, the clearance between spiral blade and inner wall reduces, and the spiral resistance increases until the spiral shaft is stuck, and the system is broken.

[0004] Therefore, the aluminium fluoride ointment spiral conveying device with cooling function is provided. CONTENT OF UTILITY MODEL

[0005] The utility model aims at providing aluminium fluoride ointment spiral conveying device with cooling function to solve the technical scheme in the background art, which reduces the temperature of spiral wall by increasing cooling water jacket and keeping cooling water circulating, and guarantees the smoothness of ointment in the conveying process.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] Aluminium fluoride ointment spiral conveying device with cooling function, including feed pipe, the feed pipe feed end is provided with feed hopper, the feed pipe discharge end passes through feed cover and extends into rotary drying kiln, be provided with feed screw in the feed pipe, the left end of feed screw extends out of feed pipe and is connected with feed motor, the outer wall of feed pipe discharge end is sleeved with cooling water jacket.

[0008] Further, the bottom of feed motor is provided with fixed seat, and the feed motor is fixedly installed on the top of fixed seat, and the top of fixed seat is close to the right side and is attached to the bottom of feed pipe.

[0009] Further, the rotary drying kiln outside and the feed cover outside connection place are installed with sealing elastic sheet.

[0010] Further, the feed hopper is vertically arranged below the aluminium fluoride ointment conduit.

[0011] Compared with the prior art, the aluminium fluoride paste screw conveying device with cooling function has the beneficial effects that

[0012] Through the cooling water jacket, the feeding screw and the rotary drying kiln, after the aluminium fluoride paste enters the inside of the feeding pipe along the feeding hopper, the feeding motor is driven, the feeding motor drives the feeding screw to rotate, the feeding screw pushes the aluminium fluoride paste in the inside of the feeding pipe to move slowly, the aluminium fluoride paste passes through the feeding cover and enters the inside of the rotary drying kiln, during which, the cooling water jacket is increased, and the cooling water circulating flow in the cooling water jacket is kept, the purpose of reducing the spiral wall temperature is realized, the smoothness of the paste in the conveying process is further realized, and the problem of material breakage in the system is avoided.
