RU146375U1 - DEVICE FOR SEALED LOADING OF BULK MATERIALS - Google Patents

Abstract

A device for the compacted loading of bulk materials into technological containers, containing a loading box, an engine and a distributor equipped with scattering plates, between which slots are formed, expanding from the center to the periphery, characterized in that the distributor is made with vertically oriented stops and has the shape of a parallelepiped.

Description

The utility model relates to the field of storage, distribution and unloading of bulk material and can be used in chemical, oil refining and other industries.

A device for the uniform loading of bulk materials [1] patent SU 1330060 with a priority of 06/26/85 IPC B65G 65/32 /, in which the loaded material is fed by gravity to the separation cones and is divided into streams filling the volume of the loaded container.

A disadvantage of the known technical solution is the low efficiency due to the uneven filling of the tank.

A device for the distribution of bulk material [2] A.S.

745357 with priority from 07/30/76 MPK2 B65G, containing a loading funnel with a horizontally located nozzle installed with the possibility of rotation around the vertical axis of the funnel. The uniform distribution of the material during loading is facilitated by the closed end ends of the tubular nozzle and the discharge openings made in its side surface.

However, the known device does not provide a seal of the loaded bulk material.

A device [3] is known for uniformly filling bulk materials of vertically standing vessels, patent RU 2317934 with a priority of July 10, 2006 IPC B65G 65/32, as well as a device for uniformly filling bulk materials of vertically standing vessels [4]

Patent RU2220085 with priority dated February 26, 02, IPC B65D88 / 54. The design of these devices includes a loading funnel (receiving hopper), a vertical shaft mounted along the axis of the loading funnel (receiving hopper) and kinematically connected with the drive of its rotation, ring plates coaxially located along the shaft.

A loading device is known for uniformly filling upright vessels with bulk material [5] RU 22370000 with a priority of 11.26.02 IPC B65D 88/54, including a vertical shaft kinematically connected with a rotation drive, with the central loading hole located in the upper smaller base of the reflective cone. The design provides a spreading disc.

All these devices are designed to fill a vertically oriented container with a stream in the form of a rain stream.

The disadvantage of the above structures can be attributed to their narrow scope - use only for vertically standing vessels.

A known apparatus for filling with a granular product or a solid granular substance [6] - patent 2067065 with a priority of 26/11/02 VGR IPC B65B 1/04. This device is equipped with a diaphragm that provides bandwidth control on the speed of rotation of the shaft with plates attached to it for spreading particles. In this case, the uniformity of filling containers of various configurations is achieved. However, its disadvantage is the complexity of the design, high requirements for precision manufacturing of parts and metal consumption.

Closest to the claimed model, the device is a device for compacted loading of bulk materials, patent RU 51600 with a priority of 08/17/05, IPC B65D 88/54. (Prototype)

In contrast to the known analogues, the slots are made expanding from the axis of rotation to the periphery and are mounted with the possibility of bias in the direction of the longitudinal edges of the bottom of the rotor. Speed control is carried out using a sensor mounted at the level of the rotor flange.

The disadvantage is the performance degradation of the boot device. As the hollow rotor is filled with bulk material, its rotation speed decreases, which negatively affects the quality of the filled layer. Some reactor vessels have small hatches. Not allowing installation inside the capacity of the loading rotor, made in the form of a circle. If foreign objects or lumps of catalyst get in, dismantle the loading machine and remove objects by disassembling and cleaning.

The objective of the proposed utility model is to increase the performance of the device for sealing the loading of bulk materials.

Technical result

an increase in the productivity of the loading device is achieved due to the uniform laying of the loaded layer both in the cross section of the technological capacity and in its height by controlling the speed of the scattering plates with slots formed between them, expanding from the center to the periphery.

Figure 1 presents a General view of the device for a compacted loading of bulk materials, consisting of a loading box 1, an air motor 2, a distributor 3 with vertically oriented stops 6.

Figure 2 presents the distributor (top view) with diffuser plates 4 and slots 5.

Figure 3 presents the distributor 3 (in the form of a parallelepiped) with vertically oriented stops 6.

The operation of the device for compacted loading of bulk materials

The feed material is fed into the loading box, and then to the distributor with diffuser plates driven by rotation of the air motor. Passing through the slots formed by the scattering plates, the material also rotates and falls down, laying in layers. The density of the layer during the entire load is the same both in the cross section of the tank and in height, and the surface is flat, without chlorine. Depending on the height and diameter of the loaded container, the speed of rotation of the distributor with the rotating plates may vary. When the particle size of the loaded material changes, the size of the slots changes. The use of the proposed device for compacted loading of bulk materials allowed to increase the productivity of the device, reduce the complexity of its maintenance and, in general, increase the quality of the reactor.
