Description

Technical Field

[0001] The invention belongs to the technical field of feeder equipment, and in particular relates to a double-drum large-volume and high-efficiency feeder casing. Background Art

[0002] The rotary feeder is also called a rotary valve, a star feeder, or an air lock. The usual rotary feeder structure is that a rotor with several blades rotates in a cylindrical casing. The material falling from the upper hopper is filled in the spaces between the blades and is discharged by the blades rotating to the bottom.

[0003] The existing rotary feeder is a single rotor. As the production volume of customers increases, the diameter and length of the rotary feeder rotor are forced to be increased to meet the transportation needs of customers. However, when the diameter and length of the rotor reach a certain value, the manufacturer's production cost doubles due to the selection of materials and the limitations of processing equipment, and the following problems exist:

[0004] 1. The increase in rotor diameter will cause the linear speed of the rotary feeder to increase in direct proportion to the diameter during rotation. At the same time, the depth of the rotor slot will also increase, causing the material to fall into the inlet of the rotary feeder and not have time to enter the next chamber of the rotor or the outlet of the feeder. The material will circulate in the rotor, causing a single-rotor large rotary feeder to be able to effectively transport only at low speeds and have no effect at high speeds.

[0005] 2. As the rotor length increases, the shaft also increases, resulting in an increase in rotational torque, which in turn increases the stress on bearings, gears and other components, shortens the service life of the components, causes instability in the mechanical system, affects system heating, and increases energy consumption. Summary of the invention

[0006] The present invention aims to at least solve the problem of reduced service life of equipment and increased maintenance cost of equipment caused by increased rotor diameter and longer rotor length.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: the present invention proposes a double-drum large-volume high-efficiency feeder housing, comprising a feed shell for rotating and conveying materials, wherein an angle dividing assembly is arranged in the feed shell to divide and convey the materials in the feed shell;

[0008] The upper and lower ends of the feed shell are respectively provided with a feed port and a discharge port.

[0009] The middle part of the feeding shell is also provided with two groups of cavities for convenient material transportation, and the angle dividing component divides the cavity into two.

[0010] As a preferred solution one: the angle dividing assembly includes two groups of reinforcing ribs fixed on the upper inner side of the feeding shell, the two groups of reinforcing ribs are symmetrical and form a triangular shape, the lower ends of the two groups of reinforcing ribs are fixedly extended to fit the cavity with an arc-shaped extension plate, and the end of the extension plate is closed by a plate body.

[0011] As a preferred solution two: the two groups of reinforcing ribs form an inverted triangular channel one, the two groups of extension plates and the plate body are sealed to form a triangular channel two, and channel two is located below channel one, and channel one and channel two are symmetrical and arranged between the two groups of cavities, and channel one and channel two realize heat dissipation.

[0012] As a third preferred solution: the size of the feed port is smaller than the size of the discharge port, ensuring that the discharge amount is greater than the feed amount.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] 1. The feed port is set smaller than the discharge port to ensure that the discharge volume is greater than the feed volume, so that there is no accumulation of material in the feed shell, which reduces the failure rate of the equipment, prolongs its service life and reduces costs;

[0015] 2. An angle dividing component is set at the center of the feeding shell to divide the cavity into two, ensuring that the material falls evenly into the two cavities, thus ensuring the integrity of the conveyed material;

[0016] 3. With the help of the strongest stability principle of the triangle plate, when the reinforcement ribs are subjected to force, the force can be evenly dispersed to the surroundings, making the overall structure more solid and safe, while playing a reinforcing role, thus avoiding various problems that may occur during the casting, production and use of the shell;

[0017] 4. The setting of channel 1 and channel 2 is conducive to accelerating the heat dissipation of the shell. The equipment can be used in conjunction with high-temperature working conditions. This design not only simplifies the shell structure, is conducive to heat dissipation and cooling, saves casting materials, but also adds a new pressure-bearing function of the shell;

[0018] In summary, the design of the present invention can reduce the output of shaft power, ensure shaft torque, and reduce costs; at the same time, different materials and special treatments can be used according to working conditions and material characteristics, and different materials can be combined and selected for each component of the main engine; it is conducive to the transportation of various materials including abrasive powders and particles, improves service life and facilitates replacement, and reduces costs; and the feeding shell has a compact structure and small volume, a simple unit structure, and is easy and flexible to assemble. Different installation methods can be selected according to customer requirements, on-site space issues, etc., so that the equipment can double its maximum production capacity. At the same time, under the same production capacity, the power is reduced by 50%, and the equipment cost and material consumption are reduced by 50%. The rotary feeder.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] The casing of the double-drum large-volume and high-efficiency feeder comprises a feeding shell 1 for rotating and conveying materials, an angle dividing assembly 2 is arranged in the feeding shell 1 for diverting and conveying the materials in the feeding shell 1; a feeding port 3 and a discharge port 4 are respectively arranged at the upper and lower ends of the feeding shell 1, and the size of the feeding port 3 is smaller than that of the discharge port 4 to ensure that the discharge amount is greater than the feed amount; two groups of cavities 5 for convenient material conveying are also arranged in the middle of the feeding shell 1, and the angle dividing assembly 2 divides the cavity 5 into two.

[0027] See also Figure 2 :

[0028] The angle dividing component 2 includes two groups of reinforcing ribs 21 fixed on the upper side of the feeding shell 1, the two groups of reinforcing ribs 21 are symmetrical and form a triangle, an inverted triangle channel 1 24 is formed between the two groups of reinforcing ribs 21, the lower ends of the two groups of reinforcing ribs 21 are fixedly extended to match the cavity 5 with an arc extension plate 22, the end of the extension plate 22 is closed by a plate body 23, the two groups of extension plates 22 and the plate body 23 are sealed to form a triangular channel 25, and channel 25 is located below channel 1 24, channel 1 24 and channel 2 25 are symmetrical and arranged between the two groups of cavities 5, and channel 1 24 and channel 2 25 realize heat dissipation.

[0029] Through direct connection installation ( Figure 3 ) or base installation ( Figure 4 ), install the feeding shell 1 and the driving device for material diversion. When feeding, the material enters the feeding shell 1 through the feeding port 3. At this time, the material enters the feeding port 3 and is first diverted into the two groups of cavities 5 by the two groups of reinforcing ribs 21, and then is rotated and separated by the logistics diversion device installed in the cavity 5, and finally discharged from the discharge port 4. With the principle of the strongest stability of the triangular plate, the force can be evenly dispersed to the surroundings when subjected to force, so that the overall structure can be more solid and safe, and at the same time play a reinforcing role;;

[0030] At this time, since the size of the feed port 3 is smaller than that of the discharge port 4, the discharge is ensured to be larger than the feed, thus avoiding the phenomenon of material accumulation in the feed housing 1;
