The invention relates to devices for vibration compaction of various materials and can be used for vibration compaction mineral-polymer mixtures.
Known vibrating platform containing installed on and connected among themselves by means of elastic elements working body and balancing frame with mounted on it buffer elements and the causative agent of oscillations (Author's certificate of the USSR №946939, CL B28B 1/08, 1980).
The disadvantage of this vibrating platform is that it can be efficiently used for sealing mineral-polymer mixtures, as the mixture is different on the size and weight of mineral fractions, which are unevenly.
Known vibrating platform containing installed on and connected among themselves by means of elastic elements working body and balancing frame with mounted on it buffer elements with the mechanism of their movement and the causative agent of oscillations (Author's certificate of the USSR №1348179, B28B 1/08, 1987).
Known device is of limited use as it does not provide control of amplitude of fluctuations in the vertical plane. In the mixture with small fractions, can be in a state of chaotic flip (if excessive vertical amplitude on this frequency oscillations)and mixtures having a large fraction, may not be compacted (with insufficient vertical amplitude on the frequency). As a result of work of the known device, the larger the mass of the particle, the faster their removal from the axis of the device to its periphery.
The technical result is the expansion of technological capabilities of the device and improving the quality and efficiency of the seals mixtures of a wide range of sizes of fractions and viscosity.
The technical result is achieved by the vibrating platform containing established on the basis and connected with elastic elements working body and balancing frame with mounted on it buffer elements with the mechanism of their movement and the causative agent of oscillations, with vertical loading of elastic elements, consisting of a system of ropes, winches tension cables with a buffer element, and balancing the frame is made in the form of a hollow box with through holes in the corners of the upper plane, and the mechanism of vertical loading of elastic elements placed inside a countervailing frames, and some of the ends of the cables are passed through holes in the corners of the upper plane and elastic elements and rigidly fixed on the corners of the working body and the other through a system of rollers on the moveable jaw, and winch tension and movable clamp connected buffer element.
The technical result is achieved due to the fact that there is a possibility to adjust the stiffness of the elastic elements between working body and balancing frame, which allows at any frequency to control the amount of vertical oscillation amplitude.
Figure 1 shows the General view of the vibration platform, figure 2 - section a-a in figure 1.
Vibrating platform contains established on the basis of balanced frame 1. On balancing frame 1 on the elastic elements 2, placed in the corners, and has a working body 3 in the form of plates with pathogens oscillations 4. Pathogens fluctuations is executed in the form of paired vibrators, frequency excite fluctuations, which may vary in some range. Balancing frame 1 is made in the form of a hollow box with the hole 5 in the corners of the upper plane. In balancing frame 1 is available mechanism of shock loading of elastic elements 2, consisting of a system of ropes 6, some ends are skipped through the corner holes 5 and elastic elements 2 and fixed in the corners of the working body 3. The second ends of the cables 6, two directly, and the other two through rollers 7 rigidly fixed on a movable clamp 8, which through the buffer item 9 is connected with tensioner in the form of a motor-reducer 10 established strictly on balancing frame 1.
The device works as follows.
On the working body 3 installed capacity with a mixture which must be sealed. Included pathogens oscillations 4 and installed the recommended frequency of oscillations. Depending on the size of fractions, the volume of the mixture and its viscosity is regulated by the stiffness of the elastic elements 2. This enables the motor-reducer 10, which tightens or weakens the system of ropes 6, squeezing or unclenching elastic elements 2. This changes the vertical amplitude of a working body 3, and consequently, the amplitude of the vertical displacement of the sealed particles of different fractions. They quickly settled, forming a tight packaging. Buffer item 9 allows damping vibrations and ensure the specified tension 6. In the process seal on a frequency, amplitude change, especially at the beginning and the end of the process seals. This allows to reduce the time, to improve the quality and efficiency of the process.
