Abstract

The invention relates to devices for feeding materials when filling sealing cords with cement formulations. The purpose of the invention is the expansion of technological capabilities by ensuring the issuance of abrasive materials. In the housing 1 with the exhaust pipe installed shaft 2, having the ability to perform a reciprocating motion along the longitudinal axis of the device under the action of the actuator. External shaft 3 and internal 4 springs are cantilevered on the shaft 2. The free end of the outer spring 3 is placed in the upper part 6 of the nozzle, and the free end of the inner spring 4 in the lower part 7 of the nozzle. During the rotational and reciprocating movements of the shaft 2, the external spring 3 continuously transports material to the upper part 6 of the nozzle, creating in it an overpressure of the material, while moving the non-fixed free end of the internal spring 4 in the confined space of the exhaust nozzle holes. 1 il.

The invention relates to chl materials feeding devices when filling sealing cords, cement compositions, in particular to devices intended for continuous supply of special cement composition when filling manufactured cement sealing cords, which are used for waterproofing the joints of cathedral tunnels of subways, and can be used in various industries to supply fine particulate materials.

The purpose of the invention is to expand the technological capabilities of the device by ensuring the issuance of an abrasive hygroscopic material.

Making the feeder from two concentrically mounted springs fixed to the shaft as a cantilever, and arranging the free ends in the upper and lower parts of the outlet nozzle allows the hygroscopic material to be unloaded.

The drawing shows the proposed device a General view in longitudinal section.

The device comprises a housing 1 and a drive with a drive shaft 2 installed with the possibility of reciprocating movement along the longitudinal axis of the device. On the drive shaft 2 a cantilever is fixed, which is made of two springs 3 and 4 installed one inside the other. The diameter of the external spring 3 is larger than the diameter of the internal spring 4. The case has a conical bottom 5 and an outlet nozzle consisting of two parts located one above the other . The free end of the outer spring 3 is placed in the upper part 6 of the nozzle, and the free end of the inner

Her spring 4 is located in the lower part of the nozzle 7.

The device works in the following way.

The case I is loaded with a finely dispersed abrasive material by any known method. The drive is turned on, as a result of which the shaft 2 performs a rotational and reciprocating motion, in which the external spring 3 constantly moves (forces) the material into the upper part 6 of the nozzle, creating in it an excess pressure. The movement of the unfixed free end of the inner spring 4 in the lower part 7 of the nozzle provides a vibratory effect in the region of this opening.

Thus, the particles of fine abrasive material constantly oscillate and are in a state of vzveschennom, what is achieved by their free passage through the exhaust pipe.
