Description

[Detailed description of the invention] Title of the invention: "Separator and method of operating the same" The present invention consists of a housing and a housing. The present invention relates to a separator having a rotor disposed within a rotor. The present invention mainly consists of , a separator suitable for separating suspended solids or liquid droplets from air. It was developed for use. An example of such a separator is British Patent 1.3 00.749. 1.369.439. 1.572.129. 1.410. 791 and 2.137.537.

The separator described in the above specification is equipped with an electric motor for driving the rotor of the separator. The rotor is usually fixed to the motor. Installed directly on the output shaft. The frame of the motor is usually A suspension system that allows limited movement of the separator connected to the The above-mentioned suspension described in the above-mentioned British patent specification The system consists of several elements, each of which is elastically deformable. They are The separator fixed to the motor and the reaction force of the torque moving on the rotor of the parts are transferred to the motor case. transmission from the thing to the housing, these elements must be fairly stiff. do not have. Furthermore, the elastic element is pressed by the weight of the motor and rotor. required to transfer the gravity loads to the separator housing. however, The elastic element described above is designed to prevent the rollover that inevitably occurs when solids accumulate unevenly on the rotor. It absorbs the vibration caused by the vibration and also weakens the vibration.

It is also possible to fix the motor casing with respect to the housing of such separators. Since the movement of the axis of rotation of the rotor relative to the housing is There is no substantial freedom to transmitted to the housing.

According to a first aspect of the present invention, a housing and a rotor disposed within the housing are provided. a mounting means for mounting the rotor to the housing, and a mounting means for mounting the rotor to the housing; In the separator, the equipment means includes a drive means for the rotor. to allow rotation of the rotor around the rotor axis relative to the housing. bearings and the rotor axis that restrains but does not impede movement relative to the housing. a suspension system, and the suspension system may include a plurality of links, each of which connects a first and a second section of the separator. The link is connected between the first and second members at each point. and wherein the suspension system restricts relative movement to the first and second including biasing means for biasing the second member toward the reference position relative to each other; A separator is available.

Each link limits the relative movement of each point between the first and second members. insofar as the separation between these points is limited to a given range, and if If the links or other components of the separator are permanently damaged, then This means that it is possible to deviate from this range. This is the type of In contrast to the elastic elements used in already known suspension systems of separators and the elastic element is configured such that the relative displacement of the first and second members increases. but does not impose a positive limit on the given displacement, making it difficult to combine these elastic elements. exerts a large restoring force on the member.

The first and second members of the separator according to the first aspect of the invention are referenced relative to each other. When in position, the link does not constrain relative movement within the allowed range, and does not transfer significant loads between the first and second members described above. Such loads The information is transmitted by ear means. If the transmission between the first and second members is When the load applied increases to a level such that the maximum range of movement allowed , the same load is imposed on the link and further relative movement is restrained. However, Therefore, the relatively easily deflectable biasing means is aligned with the rotor axis relative to the housing. can be used without the risk of causing excessive movement of the

Elastic elements that deform relatively easily are better at damping and absorbing vibrations than relatively stiff elements. suitable for income.

Furthermore, the separator according to the first aspect of the invention results in excessive stress. The risk of weakening the biasing measures is substantially avoided. Because, This is because the load that can be imposed on the biasing means is limited by the link. Ru.

According to a second aspect of the invention, there is provided a housing and a rotor disposed within the housing. The rotor is equipped with a motor for driving the rotor relative to the housing. In the method for operating a separator equipped with a motor, the motor is mounted on the housing. , the casing of the same motor is restricted by the casing relative to the housing. The rotor is connected to the housing via equipment allowing movement. The motor is attached to the output shaft of the motor, and is supplied to the motor so that it starts rotating the rotor. When energized, the torque applied to the rotor and the parts that rotate together with the rotor is A reaction force is transferred from the casing of the motor to the housing by a non-extensible link. (also partially transmitted, and when the above rotor stops accelerating, the upper The link has elasticity to transmit force between the housing and the motor casing. A separation-like actuation method is provided in which the above torque is reduced by the element. There is.

A component implementing the first aspect of the invention and operated by the method according to the second aspect. One example of a takeoff is described below with reference to the accompanying drawings.

FIG. 3 is a plan view of the portion shown in FIG. 2.

The separator shown in the accompanying figures comprises a hollow housing 10 and has a In examples, it is generally cylindrical. One end of the same housing should be attached to the same housing. It is partially closed by a cover 11 which is attached so as to be able to do so. Other end , the housing is substantially closed off by the end wall 12 .

The separator further includes a rotor 13 provided inside the housing 10. The rotor rotates about the rotor axis 14 relative to the housing 10. It is connected to the housing 1o by means of equipment provided in this manner. rotor Axis 14 extends through the center of end wall 12 and through a central opening in cover 11. There is.

The equipment means include drive means for driving the rotor 13 about the axis 14. In the illustrated example, the drive means is an electric motor 15. from a remote source of power It is understood that a pulley or other element may be substituted for the motor to receive the drive. There will be.

The motor 15 has an output shaft 16 and a casing 17 of the motor 15 that supports the output shaft. Includes bearings for The rotor 13 is fixed to the output shaft 16 but is removable. The bearings of the motor 15 define the axis 14. The motor 15 is in the housing 1o The shaft 16 extends toward the rotor 13 through a hole in the end wall 12. It is growing.

The components of the rotor 13 are as described in one of the aforementioned British patent publications. You can. The general construction and arrangement of the separator is also described in one of the aforementioned British patent specifications. The separator may be as described in used for Typically, separators empty airborne solid particles. Used to separate air and, if possible, airborne droplets . During use of the separator, the separated solid material accumulates in the rotor I3. if If such build-up is not uniform, the rotor 13 will tend to oscillate out of balance. Ru.

Although the separator suppresses the movement of the rotor axis 14 relative to the housing 10, Includes a non-obstructive suspension system. In the illustrated example, the suspension tion system between the casing 17 of the motor and the end wall 12 of the housing 1o. It has been intervened. The above suspension system alternatively uses the output shaft 16 of the motor. and the rotor 13, or between the output shaft 16 and the rotor 13. In addition, an element is interposed between the casing 17 and the housing 10 of the motor. It will be understood that it may include elements that are Above suspension system dampens the vibrations of the rotor 13 with respect to the housing 10 and partially eliminates such vibrations. If the rotor axis 14 vibrates, the housing 10 will vibrate with the same amplitude. It doesn't vibrate, and it doesn't vibrate noticeably. To achieve this, this suspension The pension system includes a motor 15 and a rotor 13 relative to the housing 10. You are required to keep them moving in a certain way.

The suspension system includes a motor casing 17 relative to the housing 10. Contains several links that restrict movement. In the particularly illustrated example, the reference numeral 1 There are four links labeled 8-21. This suspension system further Elastic elements are designated 22-25. Links 18 to 2 are rotor axis 14 , and the elastic elements 22-25 are similarly distributed.

Link 18 extends in a direction along rotor axis 14 and may be straight.

Adjacent to one end of the link, the link is mounted by means of the housing 10. The above-mentioned mounting means is connected to the end wall 12 and has only a limited range of movement. Allows displacement of the link relative to the housing 10 in a certain direction around the interaxial axis 14 do. Adjacent to its opposite end, the link 18 is similarly mounted by means of a motor. The link is connected to the casing 17, and the link moves upward in a certain direction around the axis I4. subject to limited movement relative to the casing I7, but outside the permitted range movement is completely inhibited.

Links 18 are connected to end wall 12 and casing by respective pin and slot connections. It is installed at 17. The pin 26 is fixed relative to the end wall 12; One end portion 28 of link 18 projects from end wall 12 through slot 27 .

The pin 29 is fixed with respect to the casing 17 and is attached to the opposite end 3 of the link 18. 1 protrudes from the casing 17 through the slot 30. The end portion 28 is an end wall It may be held on the pin 26 by a plate 33 in sliding contact with I2, or the end 31 may be held on the pin 26 by the plate 33. It may be held on the pin 29 by a plate 34 in sliding contact with the thing 17.

Link 18 is made of steel or other relatively rigid material and is substantially non-extendable. . The sizes of pins 26 and 29 and slots 27 and 30 vary within a given range. selected to allow separation between the axis of pin 26 and the axis of pin 29 such that ing. The range is preferably a value between 0.2 and 2+11111. illustration In the example shown, this range is expanded by slot 27 and by slot 30. Partially provided. The range of movement allowed is limited by only one of the slots. Alternatively, a circular hole into which a corresponding pin is slidably fitted is provided in the other slot. It is provided in place of. However, the links 18 are relative to each of the pins. There is enough clearance to allow some rotation.

Links 19, 20 and 21 may each be identical to link 18. this The links also connect end walls 12 adjacent their ends by pin-slot connections. and is attached to the casing 17. Fixed to the end wall 12 and connected to other links The pin 26 and the other three pins are arranged in a square. These pins are It is firmly attached. A pin 29 fixed to the motor casing 17 and other The three pins are also arranged in a square, and the pin axes are confined to the corners of this square.

Plates corresponding to plates 33 and 34 are fixed to each end of these pins and are attached to them. Each of links 19, 20 and 21 is arranged in the same manner as link 18. It is arranged in such a way.

Elastic elements 22-25 are interposed between and glued to the plates at the ends of the pins. same The resilient element connects each of the pins on the motor casing 18 to a corresponding pin on the end wall 12. It is formed so as to be biased in a coaxial relationship with. This corresponds to housing 10. In contrast, a reference position of the motor 15 is set. If the coaxial relationship of the pins is When disturbed by the reaction force of the torque supplied to the rotor 13 by the Elements 22 to 25 exert a restoring force that resets the reference position when stress is applied. let The predetermined deformation values of the elastic elements 22-25 are limited by the links 18-21. Ru.

When the motor 15 is in the reference position with respect to the housing 10, the above link No new stress is transmitted between the housing 10 and the motor 15. Force is transmitted by elastic elements 22-25. The elastic elements 22-25 are relatively It is made of a soft elastomer, for example, having a Shore stiffness of 50 or less. Motor 15 is When the elastic element 2 is at or near the reference position relative to the housing 10 2 to 25 prevent the transmission of vibration from the motor 15 to the housing 10, and Effectively weakens vibrations.

When the motor 15 is energized to start rotating the rotor 13, a relatively large torque is applied. to the rotor, shaft 16, and other parts of the motor that are fixed to the rotor 13. work.

The reaction force to this torque is transferred to the motor casing by the suspension system. is supplied to the housing 10 from the group 17. This reaction force is generated by links 18 to 21. the casing relative to the end wall 12 until a predetermined range of movement is reached. The force is large enough to rotate the rod 17. The same reaction force then links and and are collectively transmitted by the elastic elements 22-25. The rotor 13 rotates at its rated speed. When the speed is reached and acceleration is stopped, the motor 15 acts on the rotor 13. The torque decreases, and the reaction force to that torque also decreases. Generally, the reaction force is Transmission from the casing 17 of the motor to the housing 10 by means of elastic elements 22-25 the value transmitted by links 18-21. Due to the required torque, the elastic elements 22-25 are not sufficiently deformed. mosquito( Thus, during rated rotational operation, links 18-21 are substantially unstressed.

If a situation occurs where the axis 14 tends to vibrate, for example, solid matter may be present inside the rotor 13. In the case of uneven accumulation, the rotational speed of the rotor 13 is attenuated, especially after a period of operation. At times, links 18-21 collectively direct movement of axis 14 relative to housing 10. As a result, the rotor 13 does not collide with the housing 101. Li The links 18-21 also limit the deformation of the elastic elements 22-25, so these elements The element cannot be deformed to the extent that it is damaged. one or more of these elements If the rotor 13 is weakened, the position of the rotor 13 relative to the housing 10 is The control of the position of the rotor 13 is limited within the range by the never be lost.

Install links 18-21 and motor casing 17 and /% housing 10 Pins 26, 29 and 29 for mounting the elastic elements 22-25 relative to the end wall 12 of the Although it is convenient to use other pins such as It is within the scope of the present invention to space the elastic elements 22-25 from. Additionally, selective Biasing means may also be substituted in place of the elastic elements 22-25.

As mentioned above, the link 18 is in sliding contact adjacent to the motor casing 17. /or is held in sliding contact with the housing 10. The separator shown in the attached drawing is , the end of each link is in place without sliding relative to other components of the required separator. A link is shown that can be deflected or rather deformed so that a fixed displacement can be adjusted. may be modified by substitution of a hard link. For example, links 18-21 Alternatively, rope or cable formed links may be used. Like that The opposite ends of the links are firmly attached to the end wall 12 and motor casing 17, respectively. will be maintained. The middle part of the link curves slightly when the elastic elements 22-25 flex. . Each also has two rigid parts that allow limited relative movement. It is also within the scope of the invention to provide telescoping links. Relative movement is the link's Limited by open pin-slit connection of sections.
