Description
Technical Field
The invention relates to the field of mixers, in particular to a bidirectional mixer.
Background
The paper pulp is a fibrous substance prepared by using plant fibers as raw materials through different processing methods. Mechanical pulp, chemical pulp and chemimechanical pulp can be classified according to the processing method; the fiber raw materials can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, cane pulp, bamboo pulp, rag pulp and the like according to the used fiber raw materials. And can be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp and the like according to different purities. Are commonly used in the manufacture of paper and paperboard. At present, when the pulp is stirred, most of the pulp is stirred by adopting a single stirring mode, but the problem exists in that the pulp is difficult to stir completely, and a great amount of large pulp is not stirred.
Disclosure of Invention
The invention aims to solve the problem that the pulp is difficult to be stirred thoroughly by a single stirring mode in the prior art.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: a bidirectional stirrer comprises a stirring tank, wherein a first stirring mechanism and a second stirring mechanism are arranged in the stirring tank, the first stirring mechanism comprises a first motor and a first stirring piece, the first motor is arranged at the top of the stirring tank, a main shaft of the first motor extends into the stirring tank, a plurality of first stirring pieces are connected to the main shaft of the first motor, and each first stirring piece comprises a sleeve and a stirring rod; the second stirring mechanism comprises a second motor and a second stirring piece, the second motor is arranged at the bottom of the stirring tank, a main shaft of the second motor extends into the stirring tank, the second stirring piece is arranged on the main shaft of the second motor, and the second stirring piece is of a frame structure; the middle of the inner part of the stirring tank is provided with a screen, and the edge of the screen is connected with the inner wall of the stirring tank.
Preferably, the sleeve ring is sleeved on the main shaft of the first motor, and the stirring rod is connected to the sleeve.
Preferably, three stirring pieces are sequentially arranged on the main shaft of the first motor at intervals, and the lengths of the stirring rods of the three stirring pieces are different.
Preferably, the bottom of the stirring tank is provided with a supporting leg.
The invention has the following beneficial effects: the first stirring mechanism and the second stirring mechanism of the invention have opposite stirring directions, and can stir materials in two directions, so that the stirring is more thorough.

Detailed Description
The invention is further described with reference to the following figures and specific embodiments.
The two-way stirrer shown in fig. 1 comprises a stirring tank 1, wherein a first stirring mechanism 2 and a second stirring mechanism 3 are arranged in the stirring tank 1, the first stirring mechanism 2 comprises a first motor and a first stirring piece 5, the first motor is arranged at the top of the stirring tank 1, a main shaft of the first motor extends into the stirring tank 1, a plurality of first stirring pieces 5 are connected to the main shaft of the first motor, and each first stirring piece 5 comprises a sleeve 6 and a stirring rod 7; the second stirring mechanism 3 comprises a second motor 8 and a second stirring piece 9, the second motor 8 is arranged at the bottom of the stirring tank 1, a main shaft of the second motor 8 extends into the stirring tank 1, the second stirring piece 9 is arranged on the main shaft of the second motor 8, and the second stirring piece 9 is of a frame structure; the middle of the inner part of the stirring tank 1 is provided with a screen 10, and the edge of the screen 10 is connected with the inner wall of the stirring tank 1.
Preferably, the sleeve 6 is sleeved on the main shaft of the first motor in a surrounding manner, and the stirring rod 7 is connected to the sleeve 6.
Preferably, three stirring pieces are sequentially arranged on the main shaft of the first motor at intervals, and the lengths of the stirring rods 7 of the three stirring pieces are different.
Preferably, the bottom of the stirring tank 1 is provided with a supporting leg 11.
The pulp material is firstly stirred by the first stirring mechanism 2 at the upper half part of the stirring tank 1, the pulp after primary stirring enters the lower half part of the stirring tank 1 through the screen mesh 10 in the middle of the stirring tank 1, the larger material is left at the upper half part of the stirring tank 1 to be continuously stirred, and the pulp entering the lower half part of the stirring tank 1 is stirred by the second stirring mechanism 3 from the opposite direction, so that the pulp can be stirred more thoroughly. The first stirring mechanism 2 and the second stirring mechanism 3 are opposite in stirring direction and different in stirring mode, so that materials can be fully stirred, and the product quality and the production efficiency are improved.
The present specification and figures are to be regarded as illustrative rather than restrictive, and it is intended that all such alterations and modifications that fall within the true spirit and scope of the invention, and that all such modifications and variations are included within the scope of the invention as determined by the appended claims without the use of inventive faculty.
