Description

Изобретение относится к промышленности строительных материалов и может быть использовано в других областях для перемешивания вязких жидкостей.The invention relates to the building materials industry and can be used in other fields for mixing viscous liquids.

Известны смесители, содержащие установленный при помощи бандажа на опорных роликах рамы приводной барабан [1] Недостатком известных смесителей является низкая однородность смеси, получаемая только за счет вращения барабана вокруг своей оси.Known mixers containing mounted using a bandage on the support rollers of the frame drive drum [1] A disadvantage of the known mixers is the low uniformity of the mixture, obtained only by rotating the drum around its axis.

Наиболее близким решением из известных является смеситель, содержащий раму, имеющую обращенные внутрь ее ограничители, цилиндрическую емкость, установленную между ограничителями на смонтированных на раме приводных валах с закрепленными на них кулачками, эксцентриситеты ; противолежащих на соседних валах которых взаимно перпендикулярны [2 Недостатком указанных устройств является низкая надежность устройства в связи с тем, что в каждый момент времени линейные скорости точек кулачков, ле— жащих на одном валу и контактирующих с емкостью, будут разные, так как большие оси кулачков взаимно перпендикулярны. В результате этого на одном кулачке каждого из валов будет иметь место ⁵ пробуксовывание, что вызывает дополнительные затраты энергии, а также отрицательно воздействует на конструкцию.The closest known solution is a mixer containing a frame having its stops facing inward, a cylindrical container mounted between the stops on the drive shafts mounted on the frame with cams fixed to them, eccentricities; opposite on adjacent shafts which are mutually perpendicular [2 The disadvantage of these devices is the low reliability of the device due to the fact that at each point in time the linear speeds of the cam points lying on the same shaft and in contact with the tank will be different, since the large axis of the cams mutually perpendicular. As a result of this, on one cam of each of the shafts there will be ⁵ slipping, which causes additional energy costs, and also negatively affects the design.

Цель изобретения - повышение надежности устройства.The purpose of the invention is to increase the reliability of the device.

Указанная цель достигается тем, что в смесителе, содержащем раму, имеющую обращенные внутрь ее ограничители, цилиндрическую емкость, установленную ₎₅ между ограничителями на смонтированных на раме приводных валах с закрепленными на них кулачками, эксцентриситеты противолежащих на соседних валах которых взаимно перпендикулярны, кулачки выполнены в виде эксцентрично закрепленных на валах дисков, причем эксцентриситеты смонтированных на одном валу кулачков направлены в противоположные стороны, а пара смежных противолежащих кулачков выполнена по периметру с подшипниковыми обоймами.This goal is achieved by the fact that in a mixer containing a frame with its stops facing inward, a cylindrical tank installed _{) 5} between the stops on the drive shafts mounted on the frame with cams fixed on them, the eccentricities of which are opposite on adjacent shafts are mutually perpendicular, the cams are made in in the form of discs eccentrically mounted on the shafts, with the eccentricities of the cams mounted on one shaft directed in opposite directions, and a pair of adjacent opposing cams olnena the perimeter with bearing collars.

Сущность изобретения поясняется чертежом, где на фиг, 1 изображен общий вид устройства·, на фиг. 2 - вид А фиг. 1.The invention is illustrated by the drawing, where in Fig. 1 shows a General view of the device ·, in Fig. 2 is a view A of FIG. one.

Смеситель содержит закрытую крышкой цилиндрическую емкость 1 и опорные валы 2, соединенные с приводом вращения 3. На валах 2 жестко закреплены две пары эксцентричных дисков 4, причем эксцентриситеты смежных на одном валу кулачков направлены в противоположные стороны , а на соседних валах взаимно перпендикулярны.The mixer comprises a cylindrical container 1 closed by a lid and support shafts 2 connected to a rotation drive 3. Two pairs of eccentric discs 4 are rigidly fixed to the shafts 2, the eccentricities of cams adjacent to one shaft being directed in opposite directions, and mutually perpendicular on adjacent shafts.

Пара смежных противолежаших кулачков выполнена по периметру с подшипниковыми обоймами 5. Для ограничения осевого смещения емкости при вращении по ее торцам установлен^ опорные ролики 6.A pair of adjacent opposed cams is made around the perimeter with bearing shells 5. To limit the axial displacement of the container when rotating along its ends, support rollers 6 are installed.

Работает устройство следующим образом.The device operates as follows.

При включении привода 3 начинают вращаться опорные валы 2 и вместе с ними диски 4, под воздействием которых емкость 1 совершает как вращательное движение с переменной скоростью вокруг своей продольной оси (за счет эксцентрично закрепленных дисков), так’и колебательные движения относительно ее поперечной оси (за счет противоположно направленных, эксцентриситетов смежных дисков и взаимно перпендикулярных направлений эксцентриситетов противолежащих дисков). Диски 4, фрикнионно связанные с емкостью 1, являются приводными. Диски, выполнены с подшипниковыми обоймами, служат для получения колебательного движения, а также устранения пробуксовывания одного из смежных дисков на каждом валу. В зависИ4 мости от положения эксцентриситетов приводных дисков 4, подшипниковая обойма 5 диска будет получать через емкость 1 положительное или отрицательное ₅ ускорение по отношению к самому диску. Таким образом, при работе смесителя на материал воздействуют чередующиеся положительные и отрицательные ускорения в результате переменной скорости враш&10 ния емкости и одновременно радиальные ускорения в результате колебательных движений, что интенсифицирует процесс перемешивания.When the drive 3 is turned on, the support shafts 2 and with them the disks 4 begin to rotate, under the influence of which the container 1 performs both rotational motion with a variable speed around its longitudinal axis (due to eccentrically fixed disks), and oscillatory movements relative to its transverse axis ( due to oppositely directed eccentricities of adjacent discs and mutually perpendicular directions of eccentricities of opposing discs). The disks 4, friknionno associated with the capacity 1, are drive. Disks made with bearing holders serve to obtain oscillatory motion, as well as eliminate slipping of one of the adjacent disks on each shaft. Depending on the position of the eccentricities of the drive discs 4, the bearing race 5 of the disc will receive through acceleration 1 positive or negative ₅ acceleration with respect to the disc itself. Thus, during the operation of the mixer, alternating positive and negative accelerations as a result of a variable rate of rotation of the container and simultaneously radial accelerations as a result of oscillatory movements act on the material, which intensifies the mixing process.

Claims

The invention relates to the building materials industry and can be used in other areas for mixing viscous liquids. Mixers are known that contain a drive drum mounted on the support rollers of the frame using a bandage. A disadvantage of the known mixers is the low uniformity of the mixture obtained only by rotating the drum around its axis. The closest solution to the known vHbix is a mixer, supporting the frame, having inside its limiters, a cylindrical tank installed between the limiters on the frame mounted on the frame of the drive shafts with the cams attached to them, eccentricities; Opposing on adjacent shafts of which are mutually perpendicular. The disadvantage of these devices 51VL is low reliability. The devices are connected with the fact that at each instant of time the linear velocities of the points of the cams lying on the same shaft and contacting the container will be different, since the large axes of the cams are mutually perpendicular. As a result, on one cam of each of the shafts, there will be a slip, which causes additional energy costs, and also negatively affects the design. The purpose of the invention is to increase the reliability of the device. This goal is achieved by the fact that in the mixer, which contains a frame, with its limiters facing inward, a cylindrical tank installed between the stops on the frame-mounted drive shafts with cams attached to them, the eccentricities opposite to which on the neighboring shafts are mutually perpendicular, the cams are made in as eccentrically mounted on the shafts of the discs, than the eccentricities of the cams mounted on one shaft are directed in opposite directions, and the pair of adjacent opposite cams with n Odshipnikovy performed on neprnvierpy mi clips. The invention is illustrated in the drawing, where FIG. 1 shows a general view of the device, FIG. 2 - view A of FIG. 1 The mixer contains a closed cylindrical cylindrical tank 1 and support shafts 2 connected to a rotation drive 3. Two pairs of eccentric discs 4 are rigidly fixed on shafts 2, the eccentricities of the cams adjacent on one shaft are directed in opposite directions and mutually perpendicular on the adjacent shafts. A pair of adjacent opposing cams are made around the perimeter with the bearing holders 5. To limit the axial displacement of the container, when rotating along its ends, install support rollers 6 The device works as follows. When the drive 3 is turned on, the supporting shafts 2 begin to rotate and together with them the disks 4, under the influence of which the capacitance 1 performs both rotational motion with a variable speed around its longitudinal axis (due to eccentrically fixed disks) and oscillatory movements relative to its transverse axis. axes (due to oppositely directed eccentricities of adjacent disks and mutually perpendicular directions of eccentricities of opposite disks). The disks 4, which are frictionally coupled to the capacitance 1, are straight water. The disks, made with bearing collars, serve to obtain an oscillatory movement, as well as to eliminate the slipping of one of the adjacent disks on each shaft. Depending on 7 9 MOST from the position of the eccentricities of the drive disks 4, the bearing sleeve 5 of the disk will receive, through capacitance 1, positive or negative acceleration relative to the disk itself. Thus, during the operation of the mixer, alternating positive and negative accelerations as a result of the variable speed affect both capacity and radial accelerations as a result of oscillatory movements, which intensify the mixing process, affect the material. Claims of the invention: A mixer comprising a frame, having inwardly facing its stops, a cylindrical tank installed between the stops on the drive shafts mounted on the frame with the cams attached to them, the eccentricities of which are opposite to the neighboring shafts are mutually perpendicular. in order to make it more reliable, the cams are made in a vvde eccentric mounted on the shaft. discs, the eccentricities of the cams mounted on one shaft are straightened in opposite directions, and a pair of adjacent opposite cams are made in size with bearing holders.
