Vibratory device for removing bulk materials from the tank

The proposed technical solution relates to the mining and construction industries, namely to vibration devices for the release of bulk materials from containers, and can find application in unloading bunkers, as well as in other industries where unloading of containers of this type is necessary.

Known vibrational transport; its device according to ed. testimonial. No. 1803368, class B65G 27/00, publ. in BI No. 11, 1993, containing; its working body in the form of parallel elastic sheets arranged with an inclination towards the side of transportation, and vibration exciters attached to them, and mea-section sealing elements placed between the sheets. Between: this: sealing sealing elements are made in the form of trays connected to the working body by means of elastic coupling elements installed one from another at a distance multiple of the wavelength of elastic vibrations of the working body. The presence of parallel elastic sheets does not allow the effective use of this vibratory conveying device for the release of bulk materials from a tank type hopper due to the small area of vibration.

The closest analogue in technical essence and the achieved effect is a device for the release of bulk materials from the hopper according to ed. testimonial. No. 1813061, class B65G 27/00, publ. in BI No. 16, 1993, including a frame, a working body with straight and curved sections and vibration exciter. The device is equipped with frames attached to the frame in a straight section, and rollers with their covering closed flexible movable tapes forming the sides. Rollers with closed flexible movable mites are placed in frames. The disadvantage of this device is the small area of vibration on bulk material. The operation of this device is inefficient. In addition, the use of rollers located in frames attached to the frame complicates the design of the device, which reduces the reliability of its operation.

The technical task of the proposed solution is to increase operational efficiency by increasing the area of vibration exposure to bulk material, as well as increasing reliability: by simplifying the design of the device.

The task is stated as follows. A vibration device for the release of bulk materials from a container is proposed, including a flexible working body having loading and unloading parts, and a vibratory drive installed in the unloading part. According to the technical solution, the working body in the unloading part is equipped with sides located at an angle to the working body and interacting with it.

The use of boards located at an angle to the working body and interacting with it, allows you to increase the area of the vibrating surface of the discharge section of the vibrating device, which makes it possible to increase the area of vibration exposure on the produced material. This allows you to increase work efficiency. In addition, the replacement of the rollers with vibrating sides leads to increased reliability by simplifying the design of the device compared to the prototype.

The sides are freely supported on the unloading part of the working body along the line, but this is not effective enough. It is advisable to support them at several points. This makes it possible: to increase the amplitude of oscillations on the surface of the sides, which also allows to increase the efficiency of work.

In this case, it is advisable to take the distance between the nearest abutment points of the side on the unloading part of the working body equal to or a multiple of the wavelength formed in the working body. This makes it possible to excite oscillations of maximum amplitude in the sides when transmitting vibration from the working body to the sides, which also allows to increase the efficiency of this vibration device.

The essence of the technical solution is illustrated by an example of a specific design and drawings. In FIG. 1 shows a vibrating device for the release of bulk materials from a tank, a longitudinal section; FIG. 2 is a view AA in FIG. 1; FIG. 3 is a view BB in FIG. 2.

The vibrating device for the release of bulk materials from the tank (Fig. 1) includes a flexible steel working body (pos. Not indicated) for the release of bulk material 1, CONSISTING of the unloading part 2 and the loading part 3, g: tightly connected and angled to each other friend, frame 4, a vibrodrive 5 installed in the unloading part 2, and sides 6, 7 (Fig. 2), freely supported at an angle on the unloading part 2 at several points at a distance A (Fig. 3} ,, multiple wavelength forming in a working body.

The device operates as follows.

When you turn on the vibrodrive 5 in the working body vibrations occur, and the bulk material 1 under their influence moves along the working body to its discharge end. Simultaneously, the vibration is transmitted to the sides 6, 7, freely supported on the unloading part 2. This allows you to get two additional vibrating surface. In addition, the sides 6, 7, supported at several points at an angle to the surface of the discharge part 2 at a distance X that is a multiple of the wavelength formed in the working body, allow you to create directional movement of bulk material 1. In contrast to the prototype side 6, 7 are uniform surfaces, which simplifies the design of the vibrating device.

From the foregoing, 4to the area of vibration on the bulk material 1 increases, and, as a result, the work efficiency is increased. In addition, the design of the device is simplified, which means that the reliability of its operation is increased.
