Description

A multi-shaft stirring chamber for preparing silicon wafer cutting fluid

technical field

The utility model relates to the technical field of chemical industry, in particular to a multi-shaft stirring bin for preparing silicon wafer cutting liquid.

Background technique

A large amount of heat will be generated in the process of wafer cutting, which will cause damage to the blade. It needs to be sprayed with cutting fluid to cool down. Conventional silicon wafer cutting fluid requires chemical raw materials to be mixed and processed in the mixing chamber. In order to achieve the purpose of full mixing, the mixing chamber is generally A stirring paddle is provided. In order to drive the stirring paddle to achieve the purpose of full mixing, a high-power motor is required to meet the demand, and the cost is relatively high.

Utility model content

The technical problem to be solved by the utility model is to solve the technical problem of high cost of the traditional single-shaft stirring bin.

The utility model provides a multi-shaft stirring chamber for preparing silicon wafer cutting fluid, which comprises a chamber body, an inlet is provided at the upper end of the chamber body, an outlet is provided at the lower end of the chamber body, and the chamber body is movably connected with a motor driven by a motor. an active stirring shaft, the active stirring shaft is provided with a plurality of active stirring paddles located inside the silo;

The upper end of the active stirring shaft is fixed with a driving gear, the driving gear is meshed with a plurality of uniformly distributed driven gears, and the driven gears are fixedly connected with a driven stirring shaft that is movably connected to the bin body; The movable stirring shaft is provided with a plurality of driven stirring paddles located inside the silo body.

The motor drives the active stirring paddle to rotate. Under the action of the meshing of the driving gear and the driven gear, the driven stirring paddle rotates along with it, so that the cutting fluid raw materials in the silo are mixed. The single-shaft stirring paddle reduces the size, thereby reducing the burden on the motor, and using a motor with a smaller power can meet the demand and reduce the cost.

Further, the active stirring paddle and the driven stirring paddle are arranged staggered. In this way, the collision between the active stirring paddle and the driven stirring paddle can be avoided, and the cutting fluid raw materials can be mixed more quickly.

Further, the inlet is provided on the outer wall of the warehouse. In this way, the collision between the feeding tube and the gear can be avoided when feeding, which makes feeding more convenient.

Description of drawings

The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is the structural representation of the present utility model;

Fig. 2 is the front view of the present utility model, wherein the silo body is partially cut away;

In the figure: 1, silo body; 2, active stirring shaft; 3, motor; 4, driving gear; 5, driven gear; 6, driven stirring shaft; 11, inlet; 12, outlet; 21, active stirring paddle; 61. Driven stirring paddle.

Detailed ways

The present utility model will now be described in further detail in conjunction with the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

As shown in FIG. 1, the present utility model is a multi-shaft stirring chamber for preparing silicon wafer cutting fluid, comprising a chamber body 1, an inlet 11 is provided at the upper end of the outer wall of the chamber body 1, an outlet 12 is provided at the lower end of the chamber body 1, and the chamber body 1 is provided with an outlet 12. 1 is movably connected with an active stirring shaft 2 driven by a motor 3, as shown in Figure 2, the active stirring shaft 2 is provided with a plurality of active stirring paddles 21 located inside the silo body 1;

The upper end of the active stirring shaft 2 is fixed with a driving gear 4, the driving gear 4 is meshed with four evenly distributed driven gears 5, and the driven gear 5 is fixedly connected with a driven stirring shaft 6 that is movably connected with the bin body 1; as shown in Figure 2 It is shown that the driven stirring shaft 6 is provided with a plurality of driven stirring paddles 61 located inside the silo body 1; 61 collides, and also makes the mixing of cutting fluid raw materials faster;

The motor 3 drives the active stirring paddle 21 to rotate. Under the meshing action of the driving gear 4 and the driven gear 5, the driven stirring paddle 61 rotates along with it, so that the cutting liquid raw materials in the silo body 1 are mixed, and the active stirring will mix with the driven stirring paddle. Compared with the traditional single-shaft stirring paddle, the dynamic stirring paddle 61 is reduced in size, thereby reducing the burden on the motor 3, and using the motor 3 with less power can meet the demand and reduce the cost; the inlet 11 is provided on the outer wall of the silo body 1 , which can avoid the collision between the feeding tube and the gear when feeding, making feeding more convenient.

Taking the above ideal embodiment according to the present invention as inspiration, through the above description, relevant staff can make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present utility model is not limited to the contents in the description, and its technical scope must be determined according to the scope of the claims.
