Description

Technical Field

[0001] This utility model relates to the technical field of vitamin production, and in particular to a spiral feeding device for vitamin B2 production. Background Technology

[0002] A spiral feeding device for vitamin B2 production is a specialized piece of equipment designed to meet the material conveying needs during the vitamin B2 production process. The working principle of the spiral feeding device mainly relies on the rotation of the spiral shaft. When the spiral shaft rotates, the spiral blades on it push the material along the direction of movement of the spiral shaft. This pushing action enables the material to move upward or forward, thereby meeting the material conveying needs in the vitamin B2 production process.

[0003] The existing Chinese utility model patent with application number CN202220390800.9 relates to a vitamin B2 production device, which includes a shell, a rotating shaft, a connecting rod, a scraper, a stirring rod, a connecting rod, a connector, a scraper and a motor, etc., which can reduce material residue inside the device and facilitate material discharge.

[0004] However, the above-mentioned device does not have the ability to feed at a uniform rate in actual use, and the powdered raw material of vitamin B2 is prone to failure to feed normally during storage, which affects the normal output efficiency of the raw material. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a spiral feeding device for vitamin B2 production that stores and transports raw material powder through a feeding device, delivers the raw material powder to the production equipment at a uniform speed, reduces the dust overflowing during the feeding process through a dust suppression device, and reduces the situation where powder accumulates at the bottom of the feeding device and cannot be discharged normally through an auxiliary device, so that the feeding device can output powder at a uniform speed and improve the practicality of the device.

[0006] This utility model discloses a spiral feeding device for vitamin B2 production; it includes a feeding device, a dust suppression device, and an auxiliary device. The dust suppression device is installed on the feeding device, and the auxiliary device is installed on the feeding device. The feeding device stores and transports the raw material powder, delivering the raw material powder to the production equipment at a uniform speed. The dust suppression device reduces the dust overflowing during the feeding process, and the auxiliary device reduces the accumulation of powder at the bottom of the feeding device, preventing normal material discharge. This allows the feeding device to output powder at a uniform speed, improving the practicality of the device.

[0007] Preferably, the feeding device includes a storage bin, a discharge hopper, a conveying pipe, a geared motor, and spiral blades. The discharge hopper is located at the bottom of the storage bin. The left side of the conveying pipe is connected to the output end of the discharge hopper. A geared motor is installed on the left end face of the conveying pipe, and spiral blades are installed inside the conveying pipe. The output end of the geared motor is connected to the spiral blades. The storage bin stores the raw material powder, and the discharge hopper reduces the residue at the bottom edge of the powder after it is completely discharged. The geared motor is turned on to transmit power to the spiral blades, which drive the spiral blades to rotate and uniformly feed the powder out, thereby ensuring the stability of continuous production of subsequent equipment and improving the practicality of the device.

[0008] Preferably, the device also includes a rotating shaft, a cover plate, and a sealing gasket. A feeding port is provided on the upper surface of the storage silo, and a cover plate is installed on the feeding port via the rotating shaft. A sealing gasket is provided on the lower edge of the cover plate. The feeding port of the storage silo is sealed by the cover plate and the sealing gasket, which reduces the impact of the external environment on the powder in the storage silo and improves the practicality of the device.

[0009] Preferably, the dust suppression device includes an annular air pipe, an annular filter, a negative pressure chamber, and a fan. An annular air pipe is installed on the top surface of the storage silo, and an annular filter is installed on the inner side of the annular air pipe. A negative pressure chamber is installed at the upper edge of the storage silo, with its input end connected to the inside of the annular air pipe. A fan is installed outside the negative pressure chamber, with its input end connected to the inside of the negative pressure chamber. Turning on the fan extracts the gas from the negative pressure chamber and the annular air pipe, thereby removing gas from the storage silo. This reduces the pollution and waste caused by dust overflowing from the storage silo during loading. The annular filter filters dust particles, reducing raw material leakage and improving the practicality of the device.

[0010] Preferably, the device also includes a filter screen and a guide slope. A filter screen is installed inside the negative pressure chamber, and a guide slope is provided at the bottom of the negative pressure chamber. The filter screen performs secondary filtration of the gas in the negative pressure chamber, and the guide slope guides the filtered dust particles to prevent dust particles from accumulating at the bottom of the filter screen and affecting the normal airflow of the filter screen, thereby improving the practicality of the device.

[0011] Preferably, the auxiliary device includes a vibrating chassis, a discharge pipe, a support frame, a vibrating motor, and vibrating rods. The vibrating chassis is located at the lower part of the storage hopper, and a chamber is provided between the vibrating chassis and the discharge hopper. A discharge hole is located at the lower part of the vibrating chassis, and a discharge pipe is connected to the discharge hole. The lower part of the discharge pipe extends into the output end of the discharge hopper. Multiple sets of support frames are evenly arranged between the lower end face of the vibrating chassis and the upper end face of the discharge hopper. A vibrating motor is installed in the middle of the support frame, and multiple sets of vibrating rods are evenly and vertically installed on the upper end face of the vibrating chassis. When discharging powder, multiple sets of vibrating motors are activated to transmit power to the vibrating chassis and vibrating rods, causing them to vibrate. This reduces powder accumulation, collapses the cavities in the bottom powder, and allows the powder in the storage hopper to be discharged normally. The multiple sets of support frames provide auxiliary support for the vibrating chassis, improving the practicality of the device.

[0012] Preferably, it also includes a sealing ring. A sealing ring is provided on the inner wall of the lower output end of the discharge hopper, and the lower part of the discharge pipe is inserted into the area where the sealing ring is located. The sealing ring seals the gap between the discharge pipe and the output end of the discharge hopper, reducing the overflow of raw material dust and improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the raw material powder is stored and transported by the feeding device, and the raw material powder is sent to the production equipment at a uniform speed. The dust reduction device reduces the smoke and dust overflowing during the feeding process. The auxiliary device reduces the situation where the powder accumulates at the bottom of the feeding device and cannot be discharged normally, so that the feeding device can output the powder at a uniform speed and improve the practicality of the device.
