Description

Technical Field

[0001] The present invention belongs to the technical field of feeder equipment, and specifically refers to a double-barrel large-capacity high-efficiency feeder. Background Art

[0002] A rotary feeder, also known as a rotary valve, star-shaped feeder, or air-lock, usually has a rotor with several blades rotating in a cylindrical casing. The material falling from the upper hopper fills the spaces between the blades and is discharged by the rotation of the blades to the lower part. For pressure-feeding and suction-feeding pneumatic conveying systems, the rotary feeder is one of the main components. It can supply materials to the conveying pipe evenly and continuously, and in the separation and dust collection parts of the system, it also functions as a discharger. It is widely used in industries such as petrochemical, pharmaceutical, fine chemical, food processing, power plant desulfurization, fly ash conveying, cement building materials, metallurgy, and mining.

[0003] Existing rotary feeders are single-rotor. With the increase in the production volume at the customer site, the diameter and length of the rotor of the rotary feeder are forced to be increased to meet the material transportation requirements of the customer. However, when the diameter and length of the rotor reach a certain value, due to limitations in material selection and processing equipment, the production cost of the manufacturer doubles, and there are the following problems:

[0004] 1. Increasing the rotor diameter will cause the linear velocity of the rotary feeder to increase proportionally to the diameter during rotation. At the same time, the depth of the rotor groove also increases accordingly, resulting in the material falling into the inlet of the rotary feeder and not having enough time to enter the next chamber of the rotor or the outlet of the feeder, causing the material to circulate in the rotor. As a result, a single-rotor large rotary feeder can only effectively convey materials at a low rotational speed and has no effect at a high rotational speed.

[0005] 2. When the rotor length is increased, the shaft also becomes longer, leading to an increase in the rotational torque, which in turn increases the stress on components such as bearings and gears, shortening the service life of the components, and causing instability in the mechanical system. It also affects system heating and increases energy consumption. Summary of the Invention

[0006] The present invention aims to at least solve the problems of low working efficiency and small production capacity of the feeder using a single rotor, as well as the problems that increasing the rotor diameter or length affects the stable and high-speed operation of the equipment.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A double-barrel large-capacity high-efficiency feeder proposed by the present invention includes a feeding box that penetrates up and down. A partition baffle is provided in the middle of the feeding box. The feeding box is installed on a base, and further includes:

[0008] A stirring assembly: Horizontally penetrating the side wall of the feeding box to stir the material entering the feeding box;

[0009] Mixing drive assembly: symmetrically arranged on the base, connected to the mixing assembly, and a protective cover is also sleeved outside it, with one side of the protective cover fixed on the base.

[0010] Furthermore, the middle part of the feeding box is two hollow columnar boxes. The mixing assembly includes a mixing shaft rotating in the box and mounting plates installed on both sides of the feeding box. The mixing shaft is rotatably connected to the mounting plates. A number of mixing fan blades are arranged in a circumferential array on the mixing shaft for mixing the materials in the feeding box, and the mixing drive assembly is connected to the mixing shaft penetrating through the mounting plates.

[0011] Furthermore, the mixing drive assembly includes a mixing motor installed on the base. A first sprocket is provided on the output shaft of the mixing motor. The first sprocket rotates on the inner wall of the protective cover. A chain is engaged on the circumferential surface of the first sprocket, and the chain is also engaged with a second sprocket rotating on the protective cover. The second sprocket is connected to the mixing shaft.

[0012] Furthermore, the partition baffle is divided into an inverted V-shaped material distribution plate in the upper part and a connecting plate with triangular through holes. The connecting position of the connecting plate and the material distribution plate is an arc-shaped plate. The material distribution plate can divert the materials to both sides of the feeding box, and the through holes are convenient for heat dissipation.

[0013] Furthermore, symmetric feeding ports and discharging ports are provided at the top and bottom of the feeding box. The discharging port discharges the materials that enter through the feeding port and are intermittently mixed by the mixing fan blades from the feeding box.

[0014] The beneficial effects achieved by the present invention with the above structure are as follows:

[0015] 1. Through the symmetric mixing drive assembly, cooperating with the two groups of symmetric mixing assemblies in the box, the problems of low working efficiency and low production capacity of a single rotor are overcome, doubling the current production capacity, and at the same time reducing the power and equipment losses;

[0016] 2. By using the partition baffle and providing a connecting plate and triangular through holes thereon, the purposes of material distribution and heat dissipation are effectively achieved during the operation of the equipment, improving the service life of the equipment and preventing jamming during the working process.
