Description

powder mixer

technical field

The utility model relates to a mixing device, in particular to a powder material mixer used when food powder materials are mixed with each other.

Background technique

In the food processing industry, powder mixers are usually used when mixing two or more food powders evenly together, such as when adding additives to flour.

At present, the powder mixer used in the food processing industry includes a horizontally arranged mixing cylinder. One end of the top of the side wall of the mixing cylinder has a feed inlet, and the other end of the bottom of the side wall of the mixing cylinder has a discharge outlet. Rotating shafts are arranged concentrically. One end of the rotating shaft is connected with one end of the mixing cylinder through a bearing, and the other end of the rotating shaft protrudes through the other end of the mixing cylinder in a sealed rotation shape, and the extended end of the rotating shaft is connected with the output shaft of a motor, located in the mixing cylinder There are spiral propulsion blades arranged continuously from one end to the other end of the inner part of the rotating shaft, and the outer edge of the spiral propulsion blade is in virtual contact with the inner wall of the mixing cylinder. When in use, the staff first sends more than two kinds of powder materials to be mixed into the mixing cylinder from the feeding port; then, start the motor, the motor drives the rotating shaft to rotate, and the screw propeller blade rotates with the rotating shaft, so that the powder to be mixed The material is conveyed from the inlet end of the mixing cylinder to the outlet end, and the screw blades stir the materials during the process to complete the mixing; finally, the powder after mixing is discharged from the outlet. Before working on this kind of powder mixer, the staff needs to prepare the corresponding amount of powder with the help of other tools according to the proportion of the powder to be mixed, and when the amount of powder to be mixed is large, the staff also needs to prepare The good powder is divided into corresponding equal parts and added to the mixing cylinder one at a time. The whole preparation process is more complicated and consumes more manpower and time. In addition, when this powder mixer is working, only the screw propeller blades stir the powder, the stirring amount is small, and the degree of uniform mixing of the powder is low. In order to improve the uniformity of mixing, in the prior art, the method of lengthening the length of the mixing cylinder is adopted to prolong the mixing time and increase the mixing volume, but after adopting this method, the space occupied by the powder material mixer is relatively large.

Utility model content

The problem to be solved by the utility model is to provide a powder material mixer, the preparatory work of the powder material mixer is relatively simple, consumes less manpower and time, occupies less space, and has a higher degree of uniform mixing.

In order to solve the above problems, the following technical solutions are provided:

The powder material mixer of the utility model includes a horizontally arranged mixing cylinder, with a feed inlet at the top of the side wall at one end of the mixing cylinder, a discharge opening at the bottom of the side wall at the other end of the mixing cylinder, and a rotating shaft concentrically arranged inside the mixing cylinder. One end of the rotating shaft is connected with one end of the mixing cylinder through a bearing, and the other end of the rotating shaft protrudes through the other end of the mixing cylinder in a sealed rotation shape, and the extended end of the rotating shaft is connected with the output shaft of a motor, located in the mixing cylinder There are spiral propulsion blades arranged continuously from one end to the other end of the inner part of the rotating shaft, and the outer edge of the spiral propulsion blade is in virtual contact with the inner wall of the mixing cylinder. It is characterized in that the main feed pipe is connected to the feed inlet, and no less than two sub-feed pipes are connected to the side wall of the main feed pipe, and quantitative feeders are provided on the sub-feed pipes. The motor is connected with a controller through wires, and the quantitative feeders are all connected with the controller through wires. There is a helical anti-thrust leaf on the section of the rotating shaft located in the mixing cylinder, the helical direction of the helical anti-thrust leaf is opposite to that of the helical propulsion leaf, and the pitch of the helical anti-thrust leaf is smaller than the pitch of the helical anti-thrust leaf, and the helical anti-thrust leaf There is virtual contact between the leaves and the inner wall of the mixing cylinder.

Wherein, the quantitative feeder is a screw type quantitative feeder.

The above scheme has the following effects:

Since the feed port of the powder mixer of the utility model is connected with a main feeding pipe, the side wall of the main feeding pipe is connected with no less than two sub-feeding pipes, and there are quantitative feeding pipes on the sub-feeding pipes. The motor is connected to the controller through wires, and the quantitative feeder is connected to the controller through wires. There is a helical reverse thrust blade on the shaft located in the mixing cylinder, and the helical direction of the helical reverse thrust blade is consistent with the helical direction of the helical pusher blade. The direction is opposite, and the pitch of the helical reverse thrust vane is smaller than that of the helical propulsion vane, and the helical reverse thrust vane is in virtual contact with the inner wall of the mixing cylinder. Before mixing, the staff only need to put the powder to be mixed into the quantitative feeder; then, input the proportion of the powder to be mixed into the controller. When mixing, the controller can control the corresponding quantitative feeder to quantitatively send the corresponding amount of powder to the total feeding pipe according to the previously set ratio. This makes the preparatory work simpler and reduces manpower consumption. In addition, the cooperation of the helical propulsion blade and the helical reverse propulsion blade can greatly prolong the time that the material stays in the mixing cylinder, thereby further increasing the mixing capacity. Therefore, the degree of uniform mixing of the powder passed through the powder mixer of the utility model is relatively high, and the occupied space is relatively small.
