Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] like Figure 1-4 As shown, a dust drying filter comprises:

[0028] Shell barrel 1;

[0029] The crushing and drying mechanism 2 includes a spiral drum 12 rotatably connected to the shell barrel 1 and a rotating belt 23 provided on the shell barrel 1. A flow channel 122 is provided on the spiral drum 12. A plurality of crushing rings 24 are provided in a linear array on the rotating belt 23. The flow channel 122 is provided with a blocking plate 121 corresponding to each crushing ring 24.

[0030] Specifically, a heating unit is fixedly connected to the flow channel 122 (the heating unit is a device that can transport heat flow, such as a blower and a heating wire). The heating unit will transport heat flow into the flow channel 122 to dry the added powdered raw materials containing moisture. During drying, the spiral drum 12 will be driven by a driving unit (the driving unit is an electric motor) to rotate to transport the raw materials through the spiral spiral drum 12. At this time, the raw materials that are dried to form a hard shell will be crushed by the crushing ring 24 and the blocking plate 121 to break the hard shell for subsequent drying operations.

[0031] In the above technical solution, when in use, the heat flow flows in the flow channel 122, and the raw materials are added from the spiral drum 12 into the flow channel 122 for drying. During the drying process, the raw materials with lighter gravity will be blown away with the heat flow. At the same time, the spiral drum 12 will rotate slowly to drive the raw materials that have formed a hard shell to be crushed by the crushing ring 24 and the blocking plate 121.

[0032] As a further embodiment provided by the present invention, the crushing ring 24 is provided with crushing needles 241 in a circumferential array, and the blocking plate 121 is provided with crushing grooves corresponding to the crushing needles 241 , and the crushing grooves are provided with an oblique angle toward the crushing needles 241 .

[0033] Specifically, the crushing ring 24 is rotatably connected to the rotating belt 23. The crushing ring 24 is provided with crushing needles 241 in a circular array. The blocking plate 121 is provided with a crushing groove, which corresponds to the crushing needles 241. The crushing groove is provided with an oblique angle toward the crushing needles 241. When the raw material moves, the raw material that forms a hard shell will be blocked by the blocking plate 121, and then the crushing needles 241 will move with the spiral disk 12 to interlace and crush the hard shell to assist subsequent drying.

[0034] As an embodiment further provided by the present invention, a bottom barrel 3 is provided at the bottom of the shell barrel 1, an inner flow groove 13 is provided on the shell barrel 1, an upper powder flow groove 111 fixedly connected to the bottom barrel 3 is provided on the inner flow groove 13, a slit 11 is provided on the shell barrel 1, a rotating frame 22 is provided on the slit 11, a rotating belt 23 is rotatably connected to the rotating frame 22, an outer shell cover 21 is provided on the rotating frame 22, and a rotating cover 42 is provided on the inner flow groove 13.

[0035] Specifically, the bottom barrel 3 is used to carry the raw materials that have been dried. When the raw materials are dried with the heat flow and the spiral drum 12 rotates, they will accumulate at the bottom of the shell barrel 1 and enter the bottom barrel 3 along the upper powder flow trough 111 as they rotate, which is convenient for collecting the dried raw materials. The crushing ring 24 is arranged on the spiral drum 12, and the rotating belt 23 is rotatably connected to the rotating frame 22. The crushing ring 24 is arranged in the spiral drum 12. When the spiral drum 12 rotates, the crushing ring 24 will move as the spiral drum 12 pushes against it, so as to drive the rotating belt 23 to rotate along the rotating frame 22, and circulate the crushing ring 24.

[0036] As a further embodiment provided by the present invention, it further includes an upper cover 4 , a covering cover 41 is provided between the upper cover 4 and the shell barrel 1 , and an air inlet groove 421 connected to the flow channel 122 is opened on the rotary cover 42 .

[0037] Specifically, the heat flow will enter the bottom barrel 3 along the flow channel 122, and enter the inner flow groove 13 from the bottom barrel 3, and re-enter the flow channel 122 from the air inlet groove 421 on the cover 41 to realize the circulation of the heat flow and reduce heat loss.

[0038] Working principle: First, the raw material is fed into the flow channel 122. At this time, the heat flow flows in the flow channel 122, and the raw material will be added to the flow channel 122 from the spiral drum 12 for drying. During the drying process, the raw material with lighter gravity will be blown away with the heat flow. At the same time, the spiral drum 12 will rotate slowly to drive the raw material with a hard shell to be crushed by the crushing ring 24 and the blocking plate 121. The heat flow will enter the bottom barrel 3 along the flow channel 122, and enter the inner flow groove 13 from the bottom barrel 3, and re-enter the flow channel 122 from the air inlet groove 421 on the covering cover 41 to realize the circulation of the heat flow and reduce heat loss.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
