[0036] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0037] Example:

[0038] See also Figure 1-Figure 5 A bamboo pulp mixer comprises a mixing chamber 1, a mixing shaft 2, a motor 3, a mixing shovel 4, a sealing plate 5 and a connecting shaft 6. Specifically, the top of the mixing chamber 1 is an inlet, and an inlet pipe 7 is arranged on the inlet, and bamboo pulp, bleaching agent, sizing agent, etc. are added into the mixing chamber 1 through the inlet pipe 7. The bottom of the mixing chamber 1 is provided with an outlet, which is a long strip structure, and a connecting shaft 6 is arranged at the bottom of the mixing chamber 1.

[0039] One end of the connecting shaft 6 is rotatably arranged at the bottom of the stirring chamber 1, and the other end of the connecting shaft 6 is arranged along the length direction of the stirring chamber 1, and the axis of the connecting shaft 6 is located in the horizontal direction. A sealing plate 5 is fixedly arranged on one side of the connecting shaft 6, and the sealing plate 5 can cover the outlet through the rotation of the connecting shaft 6, and the outlet is completely sealed.

[0040] A stirring shaft 2 is arranged in the stirring chamber 1. The two ends of the stirring shaft 2 are rotatably arranged at the two ends of the stirring chamber 1 respectively, and one end of the stirring shaft 2 passes through the stirring chamber 1 and is connected to the output shaft power of the motor 3. The motor 3 can directly drive the stirring shaft 2 to rotate. Generally, a reducer is arranged between the output shaft of the motor 3 and the stirring shaft 2.

[0041] A stirring shovel 4 is arranged on the stirring shaft 2 , and an angle of 30°-60° is formed between the plate surface of the stirring shovel 4 and the axis of the stirring shaft 2 , so that the stirring shovel 4 is arranged on the stirring shaft 2 in an inclined state.

[0042] In the working process of this embodiment, the motor 3 drives the stirring shaft 2 to rotate, thereby driving the stirring shovel 4 to move in the stirring chamber 1, so as to stir the bamboo pulp, bleaching agent, sizing agent, etc. added to the stirring chamber 1. Since there is an angle of 30°-60° between the plate surface of the stirring shovel 4 and the axis of the stirring shaft 2, the bamboo pulp, bleaching agent, sizing agent, etc. in the stirring chamber 1 have a component moving along the axial direction of the stirring shaft 2, so that the bamboo pulp appears in an irregular motion state in the stirring chamber 1, so that the bamboo pulp is uniformly stirred. After the stirring is completed, the sealing plate 5 is separated from the outlet by rotating the connecting shaft 6, so that the bamboo pulp, bleaching agent, sizing agent, etc. in the stirring chamber 1 are all discharged.

[0043] In one specific embodiment:

[0044] The mixing blade 4 includes an L-shaped plate 41, a straight plate 42 and a support rod 43. There are four support rods 43, and there are two L-shaped plates 41 and two straight plates 42 respectively.

[0045] Specifically, one end of each of the four support rods 43 is fixedly connected to the stirring shaft 2, and the length direction of the support rods 43 is perpendicular to the length direction of the stirring shaft 2. At the same time, the four support rods 43 are respectively fixedly arranged in four directions of the stirring shaft 2, and the length directions of two adjacent support rods 43 are vertically distributed. In addition, the distances between the connection points of two adjacent support rods 43 and the stirring shaft 2 are equal.

[0046] The ends of the two support rods 43 near the two ends of the stirring shaft 2 are respectively fixedly connected to an L-plate 41, and the ends of the two support rods 43 near the middle of the stirring shaft 2 are respectively fixedly connected to a straight plate 42. The two L-plates 41 are respectively close to the two ends of the stirring shaft 2, and the two straight plates 42 are located between the two L-plates 41.

[0047] Preferably, the two L plates 41 are inclined in opposite directions, the two straight plates 42 are inclined in opposite directions, and the adjacent L plates 41 and straight plates 42 are inclined in opposite directions. In addition, the larger ends of the two L plates 41 are away from each other.

[0048] In this embodiment, the L-plate 41 and the straight-shaped plate 42 are respectively supported on the stirring shaft 2 by the support rod 43, thereby increasing the coverage of the stirring shovel 4 and improving the stirring efficiency. By arranging the L-plate 41 and the straight-shaped plate 42 to be inclined in opposite directions, the degree of disorder of the bamboo pulp, bleaching agent, sizing agent, etc. is increased, and the uniformity of stirring is improved.

[0049] In another specific embodiment:

[0050] A plurality of connecting rods are provided at the bottom of the sealing plate 5, one end of the connecting rod is fixed on the connecting shaft 6, and the connecting rod 7 is vertically arranged on the connecting shaft 6, one end of the connecting shaft 6 is rotatably arranged at the bottom of the stirring chamber 1, and a switch shaft 8 is provided at the other end of the connecting shaft 6, and the middle part of the switch shaft 8 is vertically connected to the end of the connecting shaft 6.

[0051] By providing the switch shaft 8, the force required to rotate the connecting shaft 6 can be reduced.

[0052] Preferably, a through hole is provided at one end of the switch shaft 8 , and a limiting rod 9 is slidably provided in the through hole. The limiting rod 9 and the sealing plate 5 are located on the same side of the connecting shaft 6 .

[0053] During use, when the sealing plate 5 covers the outlet, the limiting rod 9 can limit the rotation of the connecting shaft 6, thereby preventing the sealing plate 5 from being separated from the outlet. When the sealing plate 5 needs to be separated from the outlet, the limiting rod 9 can be pulled out from the through hole.

[0054] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
