Description

A new type of stirring device

technical field

The utility model relates to the field of mixers, in particular to a novel mixing device.

Background technique

The existing pulp mixer is used to evenly stir the pulp liquid in the pulp tank, and the quality of the stirring directly affects the quality of the pulp, and then affects the quality of the final paper product. Use waste cardboard, soak in water and stir to make a pulp liquid with a certain concentration. During the stirring process, you need to add some additives or gases to mix with the pulp, so as to improve the quality of the pulp, and the pulp in the pulp tank, Due to the precipitation of fibers, the uniformity of the pulp will be poor. The pulp concentration at the bottom of the pulp tank is high, while the pulp concentration at the upper part of the pulp tank is low. The uneven pulp concentration increases the defective rate of the product. Therefore, there is a need for a mixer for mixing pulp and improving the uniformity of pulp consistency.

Utility model content

The purpose of the utility model is to provide a novel stirring device to overcome the deficiencies of the prior art.

In order to achieve the above object, the utility model adopts the following technical scheme: a new stirring device, including a delivery pipe, a rotating shaft and blades arranged on the outer circumference of the rotating shaft, the upper end of the rotating shaft is connected to the delivery pipe, and the inside of the delivery pipe is set There is a lumen; the inside of the rotating shaft is provided with a rotating shaft cavity, and the side wall of the rotating shaft cavity is formed with a number of holes; the inside of the blade is formed with a blade cavity, and the blade is formed with a plurality of through holes. The lumen, the cavity of the rotating shaft, the molded hole, the blade cavity and the through hole are sequentially connected to form a conveying channel; the upper end of the rotating shaft is also provided with a transmission seat for driving the rotating shaft to rotate.

To further elaborate the solution, the lower end of the delivery pipe is formed with a slot for clamping with the rotating shaft.

To further elaborate on the scheme, the four blades are distributed in a ring shape to form a group of blades, and the two groups of blades are arranged coaxially on the outer circumference of the rotating shaft.

To further elaborate on the scheme, two adjacent blades in the blade group are separated by 90 degrees.

Further elaborating the solution, it also includes a stirring tank, and the rotating shaft and blades are placed in the stirring tank.

The beneficial effects of the utility model are as follows: the conveying channel formed by sequentially connecting the lumen, the shaft cavity, the hole, the blade cavity and the through hole can transport gas or liquid to the stirring tank, and the gas or liquid transported in is on the shaft and the blade It is fully mixed with the material under the rotation of the stirring tank; the material at the bottom of the mixing tank can be lifted up by conveying the gas to the stirring tank, and the material is stirred evenly under the action of the rotating shaft and blade stirring.

detailed description

A specific embodiment of the present utility model is introduced below in conjunction with accompanying drawing 1 to accompanying drawing 3.

As shown in Figures 1 to 3, a new stirring device includes a delivery pipe 2, a rotating shaft 1, a blade 3 arranged on the outer circumference of the rotating shaft 1, and a stirring tank 4, and the rotating shaft 1 and the blades 3 are placed in the stirring tank. The two blades 3 are distributed in a ring to form a group of blade groups, and the two groups of blade groups are coaxially arranged on the outer circumference of the rotating shaft 1; the adjacent two blades 3 in the blade group are separated by 90 degrees; the upper end of the rotating shaft 1 is connected to the delivery pipe 2, and the The lower end of the tube 2 is provided with a slot 22 for clamping with the rotating shaft 1, and the upper end of the rotating shaft 1 is fixed with a transmission seat 13 for driving the rotating shaft 1 to rotate; the delivery tube 2 is provided with a lumen 21 inside, and the rotating shaft 1 is provided with a rotating shaft cavity 11. Eight holes 12 are formed on the side wall of the shaft cavity 11; a blade cavity 31 is formed inside the blade 3, and a plurality of through holes 32 are formed on the blade. The lumen 21, the shaft cavity 11, the type holes 12, The blade cavity 31 and the through hole 32 are sequentially connected to form a conveying channel.

When the utility model is working, the drive seat 13 on the rotating shaft 1 is driven by an external motor, so that the rotating shaft 1 and the blades 3 rotate to stir the material, and at the same time, the gas or liquid can be transported to the mixing tank 4 through the conveying channel to mix and stir with the material. The gas or liquid reagent is fully mixed with the material to improve the uniformity of the material stirring.

The above description does not limit the technical scope of the present utility model in any way. All modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
