Description

Иэобретенне относитс к устройствам дл приготовлени смесей и, в частности, к смесител м длййг быстротвердеющих масс например резольно-формапьдег дных смесей ФРП..Ieobretenno relates to devices for the preparation of mixtures and, in particular, to mixers for quick-hardening masses, for example, rezol-formdegenerate mixtures of FER ..

Известен двухвальный смеситель непрерывного действи , содержащий шарнирный разъемный корпус и шнековые валы Ij.A two-shaft continuous mixer is known, comprising an articulated split body and screw shafts Ij.

Недостатком этого смесител 51вл етс необходимость ручной очистки шнековых . валов после их эксплуатации.The disadvantage of this mixer is the necessity of manual cleaning of augers. shafts after their operation.

Наиболее близким техническим решением из известных вл етс - смеситель, содержащий корытообразный корпус с ленточным шнекоми с выгрузочным отверотием .The closest technical solution known is a mixer containing a trough-shaped housing with a belt screw with a discharge hole.

Недостатком данного технического решени вл етс необходимость ручной очистки лопастей и торцевых стенок поспе их эксплуатации, что снижает производительность смесител .The disadvantage of this technical solution is the need for manual cleaning of the blades and end walls of their operation, which reduces the performance of the mixer.

Цель изобретени - обеспечение механической очистки шнека и повышение поо- изводтгельности.The purpose of the invention is to provide mechanical cleaning of the screw and increase productivity.

Г длагаемый смеситель дл быстротвердеющих масс, включающий корытообразный корпус с ленточным шнеком и с выгрузочным отвёрствем снабжен устройством дл очистки, выполненным в виде установленного на цилиндрической штанге рычага, на одном конце шарнирно закреплена ножева в лка со скосами,. а на другом - упорный ролик, контактирующий с упорным элементом, причем последний и штанга жестко закреплены на корцусе параллельно его оси.An attached mixer for quick-hardening masses, including a trough-shaped body with a belt auger and with a discharge cage, is equipped with a cleaning device, made in the form of a lever mounted on a cylindrical rod, and at one end hingedly fixed the knife in the bevelled blade. and on the other there is a stop roller in contact with the stop element, the latter and the rod being rigidly fixed on a corzus parallel to its axis.

На фиг. 1 схематически нзобрвжен см ситель, общий вид в аксонометрии; на фиг. 2 - то же, .поперечный: разрез (раврез по А-А на фиг. l); на фиг. 3 - ножева вилка в разрезе (разрез по Бна фиг. 2).FIG. 1 shows a schematic diagram, see the viewer, a general perspective view; in fig. 2 - the same. Transverse section (equalization along A-A in Fig. L); in fig. 3 - knife cut in a section (section according to Bna of Fig. 2).

Claims

The mixer includes a trough-shaped body 1, a tape auger 2 and a discharge opening 3. A cylindrical rod 4 is installed along the axis of the mixer with a two-arm lever rychagam 5 freely attached to it, at one end of which a knife-blade 6 with bevel 7 is mounted sparsely and another - a stop ropak 8, in contact with the stop element 9, a limit switch 10 is installed at the end of the body of the mixer body. The mixer works as follows: 4. The loaded mixture from the forming belt auger 2 moves along its internal line to the discharge opening 3. As it accumulates near the closed discharge outlet, the mixture rolls over the upper edge of the ribbon auger 2 and under the influence of the pressure created by the screw, it begins to move against the feed mixture ( where there is no spiral tape), Proiskoditg intensive: mixing the mixture. At the end of the unloading of the finished mixture from the discharge opening 3 to the screws 2, turning the lever 5 throws the knife fork 6. When rotating the roller 8 rests on the thrust longitudinal element 9, From the rotating screw tapee 2, the knife fork 6 with its bevels 7 starts the double cutting of the remaining screw on the masses. Under the action of a fork 6 driven by a rotating ribbon cheek 2, the lever 5 begins to move horizontally along the cylindrical rod 4, and the resistance to cutting is transmitted to roller 8, which moves along the thrust longitudinal element 9, and npenaivy the rotation of the lever 5 nor the cylindrical rod 4, the lever 5, moving along the cylindrical rod 4, in its extreme position, presses the limit switch 10, which stops the rotation of the auger 2. The internal cylindrical cavity of the mixer body is cleaned with an external, edge of continuous flax exact screw 2 when it is rotating. Such a design of the mixer minimizes the manual work on cleaning the working cavity of the mixer after operation, which increases its production. Claims of the invention A quick-hardening mass mixer comprising a trough-shaped body with a belt auger and a discharge hole, characterized in that it is equipped with a cleaning device, made in the form of a lever mounted on a cylindrical bar of the lever, and equipped with a discharge tool to increase productivity. the end of which is secured with a nozheva fork with bevels, and on the other a thrust roller in contact with the thrust element, the latter and the rod being rigidly fixed on the steam body allel to the axis.
