Description

Technical Field

[0001] The utility model belongs to the technical field of cotton delinting, specifically relates to a flame delinting device Background Art

[0002] Cotton seed processing requires the removal of residual lint on the surface of the cotton seeds. There are two methods for removing the residual lint on the surface of the seeds: one is chemical acid delinting, which mainly uses strong acids such as sulfuric acid to carbonize the residual lint on the surface of the seeds and make it brittle and fall off. This method has disadvantages such as high processing cost and high cost of waste acid treatment, and has gradually been eliminated by the market; one is flame delinting, which removes the cotton lint on the surface of the seeds by flame; and another is to remove the cotton lint on the surface of the seeds by rubbing the cotton seeds against each other.

[0003] CN102124838 discloses a flame-type cotton seed delinting device. However, this device suffers from a problem in that it cannot collect all the cotton seeds. Approximately 10% of the cotton seeds entering through the feed port are not collected, resulting in production waste. Furthermore, flame jets are emitted from the flue outlet, which compromises environmental protection and safety.

[0004] Therefore, the applicant proposed a flame-type delinting device with a simple structure and good use effect. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a flame-type delinting device which is environmentally friendly and avoids waste caused by failure to collect cotton seeds.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A flame-type delinting device includes a vertical cylindrical combustion chamber, characterized in that: a flue outlet is provided at the upper part of the combustion chamber, a seed discharge port is provided at the lower part, and a sieve plate, a seed feed port baffle and a burner are provided between the flue outlet and the seed discharge port from top to bottom. A through hole is provided on the surface of the sieve plate, one end of the baffle is fixed to the inner wall of the combustion chamber, and the other end is a free end, forming an inverted wedge shape with a larger top and a smaller bottom.

[0008] The baffle is in an inverted wedge shape and is arranged above the burner, which can prevent the seeds from sticking to the inner wall of the combustion chamber and falling and adhering to the burner.

[0009] The aperture of the through hole is smaller than the particle size of the cotton seeds, that is, the cotton seeds will not pass through the through hole.

[0010] The through hole is a circular hole or a strip-shaped hole.

[0011] The sieve plate is a steel mesh.

[0012] Compared with the prior art, the utility model has the advantages of simple structure, good use effect, and avoidance of cotton seed waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the main structure of the utility model.

[0014] As shown in the figure: 1 is the flue outlet, 2 is the through hole, 3 is the sieve plate, 4 is the shell, 5 is the seed feed port, 6 is the baffle, 7 is the burner, 8 is the seed discharge port, and 9 is the combustion chamber. DETAILED DESCRIPTION

[0015] The above content of the present invention is further described in detail below through examples. Obviously, the described examples are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0016] Example 1: Reference Figure 1 , is a structural schematic diagram of Example 1 of the present utility model, which discloses a flame-type delinting device, comprising a vertical cylindrical combustion chamber (9), wherein the upper portion of the combustion chamber (9) is provided with a flue outlet (1), and the lower portion is provided with a seed discharge port (8), and between the flue outlet (1) and the seed discharge port (8), a sieve plate (3), a seed feed port (5), a baffle (3) and a burner (7) are provided in sequence from top to bottom, wherein a through hole (2) is provided on the surface of the sieve plate (3), and one end of the baffle (3) is fixed to the inner wall of the combustion chamber (9), and the other end is a free end, forming an inverted wedge shape with a larger upper portion and a smaller lower portion.

[0017] The aperture of the through hole (2) is smaller than the particle size of the cotton seeds, that is, the cotton seeds will not pass through the through hole (2).

[0018] In actual use, cotton seed hair or pre-treated hair seed is fed into the combustion chamber (9) from the seed feed port (5). During the falling process, the hair comes into contact with the combustion flame of the burner (7), and the cotton lint on the surface of the hair seed is removed. The hair seed is discharged from the seed discharge port (8) and collected.

[0019] Since the sieve plate (3) is provided above the combustion chamber (9), it is possible to effectively prevent the smoke outlet (1) from ejecting flames outwards, and it is also possible to prevent the cotton seeds from being discharged from the smoke outlet (1) due to the rising hot air flow, thereby preventing unnecessary waste.

[0020] As a structural improvement, the through hole (2) is a circular hole or a strip-shaped hole.

[0021] As a structural improvement, the sieve plate (3) is a steel mesh.
