Description

The invention relates to the volumetric vibration treatment of ceramic parts and can be used in instrument-making, electrical and radio engineering fields.

A device for vibrating stripping of ceramic parts is known, which includes a container of rectilinear shape with loading and unloading positions located on the side wall of the container on the side of greater pressure of the working medium, as well as a device for unloading machined parts containing vibrating in conjunction with a container, connected with it by means of adjustable tg, a transport dividing grid-tray inclined relative to its side walls. The latter is placed above the working volume of the container with the possibility of overloading the working medium over it along its entire length. The transport separation grid-tray simultaneously performs the functions of a separator and a transporting body for draining the cleaned parts from the treatment area. After the processing of each batch of parts simultaneously loaded into the container, the transport separation tray-tray is periodically introduced into the working medium by means of an individual drive system 1.

However, the known device is difficult and cumbersome in design, does not ensure the continuity of the processing process. In addition, the absence of particles of the processing medium on the transport separation tray-tray during the transportation of parts after their processing and separation increases the likelihood and degree of mechanical damage to the cleaned parts, which appear as chips and excessive removal of material from certain parts of their surface.

The purpose of the invention is to simplify the design, increase productivity and improve the quality of stripping parts.

The goal is achieved by the fact that in a device for continuous vibrating cleaning of ceramic parts before firing, containing a container of straight line with end walls, which is elastically suspended and receiving oscillations from a vibrator, having parts for loading and unloading parts, as well as a device for unloading parts in the form of vibrating together with the container of the inclined transport lining tray-tray, located above the working space of the container along its entire length with the possibility of handling it whose medium, transport separator grid-tray is equipped with upper and lower screw plates, the first of which are installed obliquely in the direction of the unloading position, and the second - in the direction of the loading position, while the transport separator peujeTKa-tray is fixed on the end walls of the container with the formation of a window , and the lower screw plates are located in the working space of the container.

At the same time, the width In the transport dividing grid-tray, the angle / .. the inclination of the screw plates to the longitudinal axis of the container and the distance t between the screw

the plates are related by the ratio tgof

 -j,

In addition, the unloading position is made in the form of a channel formed by the continuation of the upper screw plates, the transport dividing grid-tray, perforated in this place, and the continuation of the inclined wall of the container.

Pa figs. 1 shows the proposed device, front view; in fig. 2 - device, plan view; in fig. 3 - section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 is a diagram explaining

the ratio of the design parameters of the device.

The proposed device for continuous vibration stripping of ceramic parts prior to their firing comprises a rectilinear container 2 mounted on a fixed frame by means of elastic suspensions 1, to which the oscillatory motion is communicated. Above the working volume of the container mounted mounted is inclined relative to its side walls of the transport partition grid-tray 3, fixed to its end walls. The width of the latter is such that, on both its sides to the side walls of the container, longitudinal OK) ia are provided for transferring the working medium to the transport separation

grid tray and back to the container. The transport separating grid is inclined towards the unloading position, located at one of the end walls of the container, with upper screw plates 4 and inclined towards the position

load, located at the end wall of the container, opposite to its unloading position, lower screw plates 5.

The lower auger plates enter the surface layer of the processing medium 6. On the side of greater pressure of the working medium (processing medium 6 with the parts being processed 7) in the container, the transport separating grid has a continuous wall 8, which enters the working medium, smoothly passing from it. P (the octeiner is closed on top 9, which has a loading hatch 10 at the loading position. To feed the parts into the container and retract them after leaving it, the device is equipped with feed And and discharge 12 conveyors. The unloading position is channel 13, which is a continuation of the last upper screw plates and a dividing grid, perforated in this place, and the space under it is bounded below by the inclined wall 14 of the container 2.

The device works as follows.

The container 2 filled with the processing medium 6 is oscillated in motion, with the result that the entire mass of the processing medium moves along a circular path in the cross-sectional plane of the container.

The feed conveyor 11 continuously feeds the parts 7 to be stripped through the loading port 10 into the container directly onto a dividing grid-tray 3, vibrating together with the container. Under the action of this vibration, the parts along the inclined plane of the dividing grid-tray enter the working volume and, together with the processing medium, move along the bottom of the container to the opposite side wall on the side of higher pressure of the working medium. Through the gap between this side wall and the vertical wall 8, which is smoothly passing from the partition grid of the tray-tray (together with the processing medium), is reloaded onto the transport partition grid, it falls into the channel between the first two upper screw plates 4 and shifts along the axis of the container side of the unloading position by an amount equal to 1.5 times the distance between the auger plastistins at the time of reaching the edge of the transport dividing grid-tray of the side wall of the container on the lower pressure side and working environment. This mixing ensures that the machined parts hit the center of the next channel between the plates when overloaded to the separation grille on the side of higher pressure of the working medium, thus preventing their contact with the ends of the screw plates, which could damage the parts. Since the transport dividing grid-tray does not have perforations within the working space of the container, the parts move along it along with the processing medium, which minimizes the contact forces between the parts being processed and the surface of the tray.

Getting into the last channel formed by the extreme upper screw plates and the dividing grid-tray, the processing medium is separated from the parts through the perforated section, made in this place in the dividing grid-tray, and along the inclined wall 14

flows back into the container, where it is evenly distributed along the entire length of the container using the lower screw plates 5. The cleaned parts on the channel 13 arrive at the exit from the container and further to the discharge conveyor 12.

The proposed design of a device for cleaning ceramic parts is relatively simple, it allows to ensure the continuity of the processing of parts, its high performance, improved product quality and can be widely used in the electrical and other industries.
