A brake cone from a brake disc and a pair of electrolytic poles located on the end surfaces of the brake disc connected through a comparison unit with a load cell.

On ft t. 1 shows the kinematic chain of a rotary chemical machine drive; in fig. 2,3 and 4 - drive, cut; in fig. 5 is a kinematic diagram of an embodiment of driving a rotary chemical machine; in fig. 6 - the same, partial section; in fig. 7 is a kinemati-xska diagram of an embodiment of a rotary chemical machine drive. The drive of the rotary chemical machine includes a bed 1, a rotor 2 mounted on the end of the rotary shaft 3 rotatably connected thereto, an engine 5 connected to the output shaft 4 connected to the input shaft 6, an overrunning clutch for connecting the shaft 3 to the output shaft 4 a reduction gear mechanism 8 located in the rotating housing 9, and a torque regulator consisting of a brake disc 10 clamped on the end surfaces of at least one brake shoe scum, and devices for controlling the drive of them displacements. Engine 5 is reversible. In order to hydride in Hodn (th shaft 6 is connected through one-way clutches 12 and 13 and a start compensator 14 to the output shaft 4 and the housing 9, the clutch 13 connects the input shaft to the housing 9 when m rotates in one of the specified directions, and the clutch 12 - input shaft with exit shaft 4, when the first one moves in the opposite direction. Output shaft 4 is completed in the block with the sun gear gear 15 of the gear reduction mechanism and is mounted for free rotation in the pods relative to the housing 9. Aligned with the sun gear gear 15 A second sun gear 16, made in a block with a hollow shaft 17, mounted rotatably in needle bearings disposed on the output shaft 4, with one end of the hollow shaft 17 protruding out of the housing 9, and secured with a braking flange 18 the disk 10. The planetary parasitic gears 19 and 20 are mounted in the supporting housing 9 on the intermediate shaft 21, while the gear 19 is engaged with the sun gear 15, gear 20 with the sun gear 16, and the intermediate shaft 21 is installed with The actuator for moving the brake pads consists of a current load sensor 23, a reversing motor, a control unit 24, a comparison unit 25 connected to the control unit and a solenoid valve 26 associated with the sensor. load and control unit through the comparison unit 25, and means 27 for vertical movement of the brake pads relative to the ends of the brake disc, such as a two-way cylinder. The current sensor 23 detects the amplitudes of the load current of the motor 5 for rotating the input shaft 6, the block 24 controls pressing the brake pads 11 to the brake disc 10 with a predetermined force, and the comparison unit 25 compares the value determined by the current load sensor 23 with the predetermined control block 24 and generates corresponding signal During the operation of the separator, a wet solid material is deposited on the inner surface of the rotor 2 and then is unloaded with a scraper (not shown in the drawing), this is created on the output shaft 4 with a torque regulator with a minimum torque. The control unit 24 sets the control parameters determined by the humidity of the treated substance, particle size, viscosity, relative humidity after processing and processing time, then the engine 5 is turned on, and the solenoid valve 26 receives a signal corresponding to the set value, while the latter opens, the result is that the brake pads And are pressed against the brake disc 10 with the necessary force, and the torque of the output shaft 4 corresponds to the specified, defined by the parameters of re-drilling. In the event of an overload of the motor 5, the solenoid valve 26 is activated by a signal from the current load sensor 23, which prevents the transfer of the overload to the motor and thus to the entire drive. The drive control device for brake pads (Fig. 3) may also include a servo motor 28, a directly coupled screw shaft 29 and a slider 30 with a nut portion 31. The nut portion is screwed onto an outer shaft 29 mounted along the brake disc 10. Servo motor 28 connected to comparison unit 25 and monitored by its signal. Using the drive control device, the brake pads 11 can freely move along the radius of the brake disc 10, while at the same time adjusting the torque to the output shaft 4 over a wide range. The torque regulator (Fig. 4) can be exhausted with an electric brake instead of a mechanical one, an electric brake contains a pair of electromagnetic poles 32 located on the end surfaces of the brake disc 10. Electromagnetic poles 32 are connected through a faucet unit 25 to a load current sensor 23 and com 24 control. The vortex points around the brake disc 10 are generated by the / magnetic flow created by the poles 32, and a reactive torque acts on the brake disc as a result of which it brakes. The magnitude of the torque applied to the output shaft 4 may vary depending on the amplitude of the control signal for the excitation of the poles 32.

The drive may include a drive distribution wheel 33, driven in rotation from the reversing engine 5 mounted on the frame 1, with the help of the drive wheel 34 and the belt transmission 35.

Rims 36 and 37 are located on the inner surface of the rotating gear 9 gear wheel mechanism, and a gear is formed along the entire inner circumference of the surface of the rims in the form of the first and second gear rims 38 and 39, respectively. The brake discs 10 are installed at both ends of the gear 9, the gear rims 38 and 39 form a planetary gearbox.

One end of the shaft 4, which is mounted along the adapter of the housing 9, is mounted in the thrust bearing 40, and the other end protrudes outside on the other side of the housing H and the other with the shaft 3 of the rotor L1uftoy 7.

When the input shaft 6 rotates in the direction of arrow A (Fig. 6), its rotation is transmitted directly to the housing. In the reduction gear mechanism associated with the output shaft 4, the latter is also rotated in the direction of the arrow A. At this (m The rotor shaft 3, coupled to the output shaft 4, rotates at a low torque and B1) at a low speed, which is necessary to separate the solid sludge suspensions from the liquid.

After completion of the separation of the drive, the drive switches to rotation with high torque and low speed to unload the slurry from the rotor with a discharge scraper, while switching is performed by a signal from the control unit (not shown in the drawings).

High torque and low rotational speed are achieved in the following manner.

The motor 5 switches the return stroke upon receipt of a control signal from the control unit and at the same time the solenoid valve 26 opens, feeds the working fluid to the pneumatic cylinder to move the brake pads, resulting in the latter being pressed to the brake disk 10 with a predetermined force, and the disk limits the rotation housing 9.

When the inlet shaft 6 is rotated in the direction of arrow B, the first planetary gear 41, which is in engagement with the sun wheel 42, rotates in the opposite direction relative to the input shaft 6 around the first intermediate shaft 43.

The first planetary platform 41 rotates in a clockwise direction around the output shaft 4 along the Birii period of the peripheral surface of the first ring 38 in the direction of arrow B, which results in lowering the lever 44, and carrying the first section of the front wheel 41, carrying the first section 41, lipache in niiravleiii-frame 1. vjioMy lunpiie sycophants; K1) Leso 46, ICH: an initiative of the arrow B, and a torque to the direction of the insole A, which rotates the second planetary luecTepino 47, which is in engagement with the second sun M wheel 46. After this moment, the mufga 48, second, disengages The planetary terrain 47 rotates freely in the direction of the j and j, and its rotation is transformed into a torque Mo mono w or Koprrjca 9 in the direction of the arrow. the second gear wheel 39. However, in this case, the rotation of the body is limited by brake elements, and it does not rotate, but the second and old wheel 47 in the direction of arrow B rotates along the inner circumferential surface of the ring gear 39, as a result of which the lever 49 rotates in Arrows B, and consequently, the output shaft 4 in the same direction at a reduced speed, this removes sediment from the inner surface of the rotor 2 of the separator.

The drive of the mohset contains three one-way clutches .50, 5 and 52 and rotates the body 9 of the redupyus gear box mechanism 8.

The reduction pkstern mechanism 8 is connected with one-way couplings 50, 51 and 52 to the output shaft 4 by a high-speed driven distribution wheel 53 and a low-speed input shaft 54, on which the driven wheel 55 is mounted, kinematically connected to the distribution wheels 56 and 57 mounted on the drive wheel 58 connected directly to the engine 5 in the same way as the high-speed distributor driven wheel 53 by means of a V-shaped 59 and 60, respectively. The torque regulator is made similarly in construction.

A liquid suspension is poured into the separator rotor 2 (Fig. 7), for example sludge, which when rotated; divided into liquid and sediment, lipn this drive motor 5 rotates the distributor wheel 56 in the direction of arrow A so that its rotation is transmitted to the high-speed driven wheel 53 rotated through the belt drive in the direction of arrow A. At JTOM the coupling 50 is fixed between the wheel 53 with the output shaft 4, connects them, and the coupling 51, which is installed between the reduction gear and the output shaft 4, disengages the latter.

In TONi, a low-speed distributor wheel 55 rotates in the same direction as the high-speed distributor wheel 53. and the one-way clutch 52 is eaten by the shaft 54 and the reduction gear mechanism, not vkik1CH: 1e C, predir.p.1pb Bpaineut.e liajia 54 in the streamer; 1ki A, all of which it rotates in the hairs of the iv reduction-movement sci-frme mechniizmu. In pc, iaie Droro Bbixoiiiioii BJJI 4 .1iiotn with HbiiuKViii ji oioCii.io, iKj-iyiaH i.i; nucHiie Hciiorpc.lCiB-iiiii; ii i; 4, oc; i 53,) ume, also with Hi.icoKoii CKi.HHiiii.ui

the separator rotor 2 rotates in the direction of arrow A for a predetermined time required for the separation of the liquid from the solid MarepHaJTa located in the rotor. Then, the driving motor 5 is reversed using a signal supplied by the control unit (not shown), while simultaneously the brake disc 10 is braked with a predetermined force determined by the M signal of the control unit. Thereafter, the wheel 53 rotates in the direction opposite to the direction of the arrow A, while the coupling 50 is disengaged and the wheel 53 is idled.

Since the HHSKOCKqjocTHoe driven follower wheel 55 and the input shaft 54 rotate in the direction opposite to arrow A, the latter and the reduction gear mechanism 8 are connected by the one-way clutch 52, the coupling 51 is turned on, and the output shaft 4 is connected with the reduction gear gear 8, and housing 9, due to the restriction of its rotation through the brake disc 10, does not rotate. As a result of rotation of the coupling 51 in the direction opposite to arrow A, the shaft 4 and the reduction gear mechanism 8 are connected.

Thus, the low-speed rotation transmitted to the shaft 54 is further pushed through the reduction mechanism and transmitted to the shaft 4 to rotate at a low speed and high torque proportional to the force limiting the rotation of the housing 9.
