Description

Technical Field

[0001] The utility model belongs to the technical field of material feeding, in particular to a water-cooled quantitative spiral feeding device. Background Art

[0002] Feeder is a feeding machine in the general sense. It has different names because of different names in different places. Its essence and function are basically the same. There are many types of feeders, generally including vibrating feeders and screw feeders. Some solid particle dusts need to use screw feeders. Most of the existing screw feeders have a spiral dragon set in the shell. The motor drives the spiral dragon to rotate, thereby transporting the material from a low place to a high place. The speed of material transportation is controlled by controlling the speed of the motor. Since powder and smaller particles are easily blocked at the discharge port during transportation, the material transportation in the existing technology is inconvenient, and there are large differences in the amount of transported material. Therefore, the spiral feeding device in the existing technology is inconvenient to feed and the quantitative transportation is inaccurate. Utility Model Content

[0003] In order to solve the technical problems of inconvenient feeding and inaccurate quantitative delivery of a spiral feeding device, the utility model provides a water-cooled quantitative spiral feeding device, comprising a shell, a vertically arranged bearing assembly is fixed to the bottom end of the shell, a vertically arranged rotating shaft is rotatably assembled in the bearing assembly, a hopper with an open top is fixed to the top end of the shell, a stirring mechanism is assembled on the rotating shaft in the hopper, and the stirring mechanism includes a plurality of material stripping plates, which are detachably fixed to the rotating shaft by fixing bolts. When material is placed in the hopper, the rotating shaft drives the material stripping plates to stir and mix the material. A plurality of impellers evenly spaced along the circumference of the rotating shaft are fixed on the rotating shaft below the stirring mechanism, and horizontally arranged air inlet pipes are fixed on the left and right sides of the shell. A discharge pipe corresponding to the air inlet pipe is fixed at the bottom end of the shell. The bottom end of the bearing assembly is equipped with a driving mechanism for driving the rotating shaft to rotate. The driving mechanism includes a reducer fixed at the bottom end of the bearing assembly and a driving motor fixed on the reducer. The power output shaft of the driving motor is connected to the power input shaft of the reducer, and the power output shaft of the reducer is connected to the rotating shaft. The driving motor is started, and the driving motor drives the impeller to rotate through the rotating shaft. The impeller sends the material in the hopper to the upper end of the discharge pipe. The air inlet pipe is ventilated and blows the material out of the discharge pipe. The falling speed of the material in the hopper is adjusted according to the speed of the impeller, thereby realizing quantitative feeding.

[0004] Preferably, the stripper plate is circumferentially arranged around the rotation axis.

[0005] Preferably, the included angle between the discharge pipe and the rotating shaft is α, and 15°≤α≤45°, which is convenient for material discharge.

[0006] Preferably, a cold water circulation pipe for cooling the material is provided on the inner wall of the shell, and the cold water circulation pipe is connected to the cold water circulation system.

[0007] Preferably, the air intake pipe in the housing is sleeved with a rubber pad for sealing.

[0008] Preferably, a cover plate is provided on the shell below the hopper, and a material drop hole is opened on the cover plate.

[0009] The above solution has the following advantages:

[0010] The setting of the stirring mechanism can stir and mix the materials put into the hopper, and at the same time break up the large and compacted particles or powder materials, which is convenient for quantitative feeding, and can also reduce the blockage of the discharge pipe by the material; the setting of the air inlet pipe and the air outlet pipe can ventilate the shell and the discharge pipe through the air inlet pipe, which is convenient for quickly blowing out the material in the discharge pipe, thereby improving the blanking efficiency and reducing the probability of the discharge pipe being blocked by the material; the setting of the impeller can control the speed of the impeller through the driving mechanism to achieve quantitative feeding.
