Description

A central feeder for internally driven bins

technical field

The utility model relates to a material bin center feeder, in particular to an internally driven material bin center feeder.

Background technique

At present, the structure of small and medium-sized storage bins is mostly a cylindrical or cuboid structure with a straight section at the upper end, and a towering inverted cone structure at the lower end, with a high overall height. The unloading method of the storage silo is mostly gravity unloading. Since the lower end of the storage silo is a towering inverted cone, after a period of use, there will be various degrees of material blocking. The current solution to the problem of material blocking is The technology includes the following methods: First, by installing a hydraulic dredging device inside the inverted cone, start the hydraulic dredging device to dredge the material in the cone after the material blocking occurs, and improve the fluidity of the material in the cone. Second, by inlaying stainless steel or high polyvinyl chloride lining boards inside the inverted cone, the friction between the material and the inner surface of the inverted cone is reduced, so as to improve the fluidity of the material in the cone. Third, by installing vibrator, air cannon and other devices on the outer surface of the inverted cone, start the vibrator and air cannon device after the material blocking phenomenon occurs, and improve the material by vibrating or suddenly blasting the material in the cone Mobility within the cone.

Combined with the actual use situation, aiming at the above-mentioned storage bin and three different ways to solve the material blockage, the central feeder of the bin is designed, so as to solve the following shortcomings: the storage bin itself has high height and low space utilization rate. Low cost, large investment, and easy blockage of materials; the three ways to solve blockages are all compensatory measures, which have poor adaptability to different materials and ineffective effects, and cannot fundamentally solve the problem of excessive height of storage bins and limited space. Problems such as low utilization rate, large investment, and easy blockage of materials. However, this external drive structure outside the silo is easily limited by the space layout, and the sealing performance of the entire silo is poor.

Utility model content

The purpose of the utility model is to solve the problem that the outer driving structure feeder of the silo is easily restricted by the space layout, and the sealing performance of the whole silo is poor, and further proposes an inner drive silo center feeder.

The technical scheme that the utility model adopts for solving the above problems is:

A central feeder for an internally driven silo, comprising a storage silo, a chassis, an inner cone, a central outlet and a driving device, the inner cone is fixed inside the storage silo, the inner cone is a hollow structure, and the center The discharge port is fixed at the bottom of the chassis and communicates with the storage bin. It also includes a discharge arm. The chassis is fixed at the outlet below the storage bin. The flange plate is affixed, the unloading arm is located between the inner cone and the chassis, and one end of the unloading arm is affixed to the output shaft of the drive device.

The beneficial effects of the utility model are:

The drive device is fixed inside the inner cone, which effectively utilizes the hollow structure of the inner cone. Compared with the existing feeder with drive structure outside the silo, it does not need to be limited by the space layout and occupies less space;

The central discharge port is fixed under the chassis and communicates with the storage bin, and the driving device is also installed inside the inner cone. Compared with the existing external drive structure feeder, the sealing performance is better, especially suitable for Some special materials, such as toxic materials, volatile materials, etc., can isolate the special materials from the outside world and have higher safety.

detailed description

Specific Embodiment 1: This embodiment is described in conjunction with FIG. 1 and FIG. 2. An inner-driven bin center feeder described in this embodiment includes a storage bin 1, a chassis 5, an inner cone 2, and a driving device 3 And the center discharge port 6, the inner cone 2 is fixed inside the storage bin 1, the inner cone 2 is a hollow structure, the center discharge port 6 is fixed below the chassis 5 and communicates with the storage bin 1, its It is characterized in that it also includes a discharge arm 8, the chassis 5 is fixed at the outlet below the storage bin 1, the driving device 3 is arranged inside the inner cone 2 and is fixedly connected with the flange 21 at the lower end of the inner cone 2 , the unloading arm 8 is located between the inner cone 2 and the chassis 5 and one end of the unloading arm 8 is fixedly connected to the output shaft 31 of the driving device 3 .

The unloading arm 8 is a strip-shaped plate and is bent with a certain radian, so as to scrape the material into the central discharge port 6 when the unloading arm rotates around the output shaft of the driving device.

The output shaft 31 of the driving device 3 drives the unloading arm 8 to rotate. Through the rotation of the unloading arm 8, the materials in the storage bin 1 are evenly and orderly transported to the next-level conveying equipment according to the first-in first-out unloading principle. Avoiding the dead angle of unloading can completely eradicate the possibility of various blocking phenomena of bulk materials in the storage bin 1 .

The output speed of the driving device 3 can be automatically adjusted according to the needs to control the flow of the material.

Without changing the volume of the storage bin 1, the height of the diameter section at the upper end of the storage bin 1 is increased, the size of the outlet at the bottom of the storage bin 1 is increased, and the overall height of the storage bin 1 is reduced. Compared with the prior art, the The height of the storage bin 1 is reduced, which has the advantages of high space utilization rate, small footprint, and reduced cost of related projects.

Specific embodiment 2: This embodiment is described in conjunction with FIG. 1 . An internally driven silo center feeder described in this embodiment, the internally driven silo center feeder also includes a support arm 4 and an inspection channel 7. The storage bin 1 and the inner cone 2 are fixedly connected by the support arm 4 , and an inspection channel 7 is provided between the storage bin 1 and the inner cone 2 . In this way, the inner cone 2 is fixed in the storage bin 1 through the support arm 4 , and the interior of the inner cone 2 can be overhauled through the inspection channel 7 , and it also plays the role of assisting in fixing the inner cone 2 . Other compositions and connections are the same as those in the first embodiment.

Specific Embodiment 3: This embodiment is described with reference to FIG. 1 . In the inner-driven silo center feeder described in this embodiment, the support arm 4 and the maintenance channel 7 are both horizontally arranged at the lower part of the inner cone 2 . In this way, the diameter between the middle section and the lower section of the inner cone 2 is relatively large, and one end of the support arm 4 is fixed within this range to make the fixing of the inner cone 2 more firm. At the same time, because the driving device 3 is arranged on the inner cone 2, when the drive device 3 is overhauled, the closer the inspection port of the inspection channel 7 is to the drive device 3, the more convenient the inspection is, and the inspection port is located between the middle section and the lower section of the inner cone 2, and the inspection port range is larger. It is more conducive to overhauling the interior of the inner cone 2 . Other compositions and connections are the same as those in the second embodiment.
