DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0019] Reference Figure 1 and Figure 2 As shown: A cooling machine includes a housing 1. In this embodiment, the housing 1 is made of stainless steel.

A stirring shaft 5 arranged horizontally is installed in the housing 1. Both ends of the stirring shaft 5 extend out of the housing 1, and one end is connected to a first bearing seat 6, and the other end is connected to a driving device 8 through a second bearing seat 7. A plurality of stirring rods 9 with uniform intervals are vertically penetrated in the axial direction of the stirring shaft 5 in the area located in the housing 1. The stirring rod 9 is provided with a first outer spiral blade group, a first inner spiral blade group with a rotation direction opposite to the first outer spiral blade group, and a second outer spiral blade group and a second inner spiral blade group symmetrical with respect to the axial direction of the stirring rod 9 and the first outer spiral blade group and the first inner spiral blade group. The tail of the first outer spiral blade group, the tail of the first inner spiral blade group, the head of the second outer spiral blade group and the head of the second inner spiral blade group are staggered and connected to the same stirring rod 9 located directly above the discharge port 2. In this embodiment, when in use, the material to be cooled is conveyed to the inside of the shell 1 through the feed port 3. After the conveying is completed, the fan and the drive device 8 are started. The fan cools the inside of the shell 1. The drive device 8 drives the stirring shaft 5 to rotate. The rotation of the stirring shaft 5 drives the first outer spiral blade group, the second outer spiral blade group, the first inner spiral blade group and the second inner spiral blade group to rotate. The first outer spiral blade group cooperates with the second outer spiral blade group to convey the material from the two sides of the shell 1 to the center, and the first inner spiral blade group cooperates with the second inner spiral blade group to convey the material from the center of the shell 1 to both sides, forming convection stirring cooling, thereby achieving the technical effect of efficiently and evenly cooling the material. When the cooling is completed, the material can be discharged through the discharge port 2.

[0020] In a preferred embodiment of the present invention, the first outer spiral blade group is composed of a plurality of first outer spiral blades 10 wound side by side on the stirring shaft 5 along the conveying direction, the first inner spiral blade group is composed of a plurality of first inner spiral blades 11 wound side by side on the stirring shaft 5 along the conveying direction, the second outer spiral blade group is composed of a plurality of second outer spiral blades 12 wound side by side on the stirring shaft 5 along the conveying direction, and the second inner spiral blade group is composed of a plurality of second inner spiral blades 13 wound side by side on the stirring shaft 5 along the conveying direction. This arrangement enables the spiral blades to be replaced individually, thereby effectively reducing maintenance costs.

[0021] In a preferred embodiment of the present invention, the driving device 8 is a motor installed on the frame, and the motor is transmission-connected to the second bearing seat 7 via a reducer.

[0022] In a preferred embodiment of the present invention, flanges are provided on both the feed port 3 and the discharge port 2, so that it is easy to disassemble and assemble the feed pipe and the discharge pipe.

[0023] In a preferred embodiment of the present invention, an observation window is sealed and embedded in the top of the housing 1, so that the user can easily understand the situation inside the housing 1.

[0024] In a preferred embodiment of the invention, an annular flange is provided on the inner wall of the inlet end of the air duct 4, and a filter screen is detachably mounted on the annular flange. This arrangement can effectively prevent dust from entering the interior of the housing 1 and causing contamination to the material.

[0025] In a preferred embodiment of the invention, the filter screen and the annular flange are connected in the following manner to achieve a technical effect of convenient assembly and disassembly: a plurality of first bolt holes are evenly arranged on the annular flange, and second bolt holes matching the first bolt holes are arranged on the edge of the filter screen, and the first bolt holes and the second bolt holes are connected by bolt threads.

[0026] In a preferred embodiment of the invention, the filter is coated with a super-hydrophobic nanoporous coating, which facilitates the subsequent cleaning of dust and other dirty particles on the filter.

[0027] In summary, the present invention provides a first outer spiral blade group, a first inner spiral blade group with a rotation direction opposite to that of the first outer spiral blade group, and a second outer spiral blade group and a second inner spiral blade group that are symmetrical with the first outer spiral blade group and the first inner spiral blade group about the axial direction of the stirring rod 9 on the stirring rod 9 that is evenly and vertically penetrated on the stirring shaft 5 at equal intervals, and the tail of the first outer spiral blade group, the tail of the first inner spiral blade group, the head of the second outer spiral blade group and the head of the second inner spiral blade group are staggered and connected to the same stirring rod 9 located directly above the discharge port 2. This allows the first outer spiral blade group and the second outer spiral blade group to cooperate to transport materials from both sides of the shell 1 to the center, and the first inner spiral blade group and the second inner spiral blade group to cooperate to transport materials from the center of the shell 1 to both sides, forming convection stirring cooling, and the inside of the shell 1 is cooled by a fan connected to the shell 1, so that the cooling machine can efficiently and evenly cool the material, and has the advantages of high cooling efficiency, good cooling effect and effective guarantee of material quality.
