Description

TECHNICAL FIELD

[0001] The utility model relates to a powder removing device, especially a powder removing device and system for puffed feed oil spraying, which is used for removing powder before puffed feed particle oil spraying, reducing the powder adhesion on the surface of the particle feed, avoiding waste of oil and so on, and belongs to the technical field of feed production. BACKGROUND

[0002] In the production process of puffed feed, oil is sprayed on the surface of the particle feed to improve the palatability and digestibility of the feed, increase the nutrient concentration and energy content, and also inhibit dust flying and reduce environmental pollution. Before spraying, the particle feed needs to be screened by a rotary grading screen to screen out large impurities and part of the fine powder. However, due to the fact that the particle feed itself contains a certain amount of oil, part of the fine powder adheres to the surface of the particle and cannot be cleaned by the screen. After the powder-containing particles are sprayed with oil, part of the fine powder wrapped on the outside of the particles falls off in the subsequent cooling, screening and packaging processes, causing cross-contamination in the subsequent production, and the other part causes water pollution and waste when feeding fish and other livestock.

[0003] Although the prior art CN105665272A discloses a fish feed spraying and grading device to prevent oil waste and air pollution, the fish feed grading and spraying processes are performed simultaneously, and an ultrasonic vibration nozzle is used as the oil spraying nozzle to disperse the oil into small particles, ensuring complete fish feed spraying and saving oil; a cooling box and an oil-water separation device are provided to recycle unused oil. CN205324152U discloses a feed vibrating screen powder removing system, which is mainly used for powder removal during particle feed screening.

[0004] Therefore, there is a need for an equipment for removing fine powder after particle feed screening and before oil spraying. SUMMARY

[0005] To solve the above technical problems, a powder removing device and system for puffed feed oil spraying are proposed. In this technical solution, a powder removing device with a specific structure is provided to remove fine powder from the screened particle feed, facilitating the effectiveness of the subsequent oil spraying process to meet the actual production needs.

[0006] To achieve the above technical purposes, the following technical solutions are proposed:

[0007] The first purpose of the technical solution is to provide a powder removing device for puffed feed before oil spraying, which comprises a shell, a feeding port arranged at the top of the shell, a discharging port arranged at the bottom of the shell, a air supplementing port arranged at the left side of the shell and an air outlet arranged at the right side of the shell; a guide plate is arranged in the shell, the upper end of the guide plate is fixedly installed at the right side of the feeding port, the lower end of the guide plate extends to the lower side of the air supplementing port, and a channel I for material flow is formed between the inner wall of the shell and the left side of the guide plate;

[0008] A channel II for material flow and air flow is formed between the inner wall of the shell and the lower end of the guide plate.

[0009] A continuous path for material conveying is formed between the feeding port, the channel I, the channel II and the discharging port.

[0013] Further, a perforated baffle for avoiding impurities from entering is arranged in the air supplementing port. For example, in actual production, mice, ropes and other impurities may enter the powder discharger through the air supplementing port, which seriously affects the entire feed production line.

[0014] Further, the air outlet is connected with the air blower through an air outlet pipeline, a pulse dust collector and an adjusting valve for adjusting the air volume are further arranged on the air outlet pipeline, the pulse dust collector is arranged on the front side of the air blower, and the adjusting valve is arranged on the front side of the pulse dust collector; an air blower is arranged at the bottom of the pulse dust collector. The arrangement guarantees that the air successfully and stably carries the fine powder and separates the clean feed particles under the action of the air blower and the air supplementing port, and the dust-carrying air is discharged after dust removal, improving the environmental protection.

[0015] Further, the feeding port is connected with a feeding chute, and the discharging port is connected with a discharging chute.

[0016] The second purpose of the technical solution is to provide a powder removing system for puffed feed before oil spraying, which comprises the above-mentioned powder removing device.

[0017] Further, the powder removing device is arranged between a rotary grading screen and an oil spraying device, the feeding port of the powder removing device is connected with the material outlet of the rotary grading screen through a feeding chute, and the discharging port of the powder removing device is connected with the material inlet of the oil spraying device through a discharging chute.

[0018] The rotary grading screen, the feeding chute, the powder removing device, the discharging chute and the oil spraying device form a continuous path for the screening, powder removing and oil spraying of the pellet feed.

[0019] The terms "top", "bottom", "left side", "right side", "inner", "upper end", "lower end", "lower side", "between", "below", "upper right", "front side of the process", "between" and the like in the technical solution are defined according to the actual use state and are conventional terms in the technical field, and are also conventional terms of the technical personnel in the actual use process.
