Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying vise such as a pump or a motor.

West German Patent No. 6243, British Patent Specification No. 208477
No., @562409, No.1152912 and! 13
No. 42,847 and US Pat. No. 2,794,400, etc., propose I-iaphram pumps.

These pumps include a housing having an interior surface and a flexible resilient diaphragm mounted within and secured to the housing to form a chamber with the interior surface. The /ring is provided with first and @2 ports which communicate with the chang/4. A number of deflectors on the roller cape are sequentially maneuvered away from the chamber and over the five sides of the membrane flange to urge the diaphragm against the interior surface to form a closure across the chamber. The closure portions are respectively connected from the first hoard to the second hoard.
before the formation of one closure is completed, the formation of the next closure begins. The disadvantages of such a construction are that the diaphragm must be resilient in order to achieve the required shape, and that the diaphragm tends to bend toward the low pressure side of the pump.
Therefore, the slug of material being pumped
)". For this reason, this rare pump is also limited in terms of size and the low rotational speeds at which it can operate.

British Patent Application No. 80373704+ discloses that the flexible diaphragm cannot be substantially stretched lengthwise and that the deflector is substantially along a path on the surface of the diaphragm remote from the chamber. When moving, the sum of the distance measured along the diaphragm between a fixed point of the diaphragm and the deflector adjacent to this fixed point and the distance measured along the diaphragm between adjacent deflectors as a characteristic book is essentially An l/de arrangement has been proposed in which the ratio is constant. The housing has a first surface having a lower constant surface.
and a second portion having an upper fixing surface. The fixing wi is shaped to give the correct positioning of the bond and the rotor supporting the deflector can be mounted on the first housing part. The length of the diaphragm is substantially constant in any position of the deflector means so that the diaphragm does not fall out of the pressure reduction area or extend into the housing. This allows the bonder to operate at relatively high speeds and relatively high pressures for relatively light materials 1jK containing slurry. Bondes are able to perfectly and adequately convey extremely heavy materials such as mortar or concrete.

According to the invention, it is then proposed to mount deflector means on the 20th No. 1 housing part, that is to say on the part of the diaphragm which has an internal surface against which it is pressed by the deflector means. Although this is achieved by providing mounting projections on the sides of the second housing part, this may lead to casting problems if the second housing part is cast. This also causes problems when machining is performed. Therefore, it is preferred to mount the bracket on the second housing part. A bracket can be used to position the rotor laterally, and also allows adjustment of the rotor's position in the vertical direction. One of the easiest ways to make this vertical adjustment is to
A shim adjuster or slurry adjuster would be used under the bearing pedestal used to mount the rotor. Alternatively, one end of the bracket can be pivotally mounted, while the other end can be moved up and down in various ways. A bearing pedestal or other bearing can be mounted on the secondary frame. One end of this sub-frame is rotatably mounted on the second housing part.

Therefore, the 10th position where the rotor assembly is in operation and the 2nd position when the sub frame is not engaged at all.
The secondary frame and rotor assembly can be pivoted to and from a remote position. In this way, the diaphragm can be subjected to a capacitance conversion. Normally, provision will be made to securely fix the sub-frame in the first position.

Another possibility is that if the diaphragm is excessively distorted by passing solids into the chamber, the secondary frame should be moved slightly apart so that the rotor assembly can move slightly apart.
The method is to provide elasticity to the position and hold it, for example, by a spring force. Priming the pump to be started allows the pressure on the deflector on the diaphragm to increase, and then priming the deflector on the diaphragm to allow the pressure on the diaphragm to decrease as the fluid itself is being pumped. The position of the pivot point of the secondary frame or rotatably mounted bracket in the operating state of the I7 may be adjustable so as to condition the pressure. This adjustment can be done manually or using a hydraulic actuator.

1. The first no-uzong part and the second no-usage part O such that in the fully fixed state, the fixing surfaces are spaced apart by a substantially constant distance over the entire station. It is advantageous to form cooperating fastening surfaces. This ensures a relatively uniform fixing effect when the two hauzonda parts are fixed to the periphery of the diaphragm.

Two rollers are in contact with the diaphragm at the same time for a considerable amount of time!
In order to ensure that IK, it is preferable to extend each end of the arcuate portion of the trough by a considerable amount, essentially a portion of a circle centered on the center of rotation of the rotor; in this way the rollers are The amount of lip of material pumped through can be substantially reduced.

Tightening to hold two Uzong parts together? The bolts are arranged along the sides of the housing (perpendicular to the axis of rotation of the rotor) as well as along the ends of the housing.

Through-holes may be provided in the lateral edges and/or in the Fi-width and rear edges of the diaphragm. In order to prevent these bindings of the diamond 7 from being stretched by the passage of the deflector, the above-mentioned attachment elements, such as belts, extend through this hole.

In order to reduce wear on the diaphragm when the deflector is of the roller type, it is proposed according to another feature of the invention to pass the belt around the roller enclosure. Teeth are attached to the inside of the belt for cooperation with toothed rollers. The belt can be distributed so that it does not move at all relative to the diaphragm, and can actually be physically secured to the diaphragm. If there is no relative movement between the belt 5 and the diaphragm, the wear of the deflector on the KFi and Meier dimes can be significantly reduced. Of course, if the belt itself becomes worn, it can be replaced more easily than the diaphragm.

Alternatively or additionally, the diaphragm may include two or more platelets. One plate forms the deformable wall of the chamber, and a further plate or plates is arranged between this wall and the deflector. The plate surface adjacent to said one plate may be provided with a notch or indentation extending generally parallel to the rotor axis supporting the deflector. These notches or notches bend open as the deflector passes over the opposing surface to relieve strain on the diaphragm. Of course, the knot does not extend until the length of the diaphragm increases.

Therefore, the extensibility of the diaphragm will not be affected by the notch.

It is also contemplated that a replaceable pad, energized on the inside surface of the housing, may be placed in the housing to define one wall of the chamber. If the pads are worn out, such pads can be replaced, especially when pads are used with abrasive fluids. It will be, frad can be rigid or elastic. In this case the nut will usually be constructed as a molded pum nut or an indica of a similar material. A portion of this molded India is molded into an annular shape and joined to the Nen Grate. This plate is bent so that it has a radius fr larger than the radius of the inner surface of the second housing part in the direction in which it is mounted. If this plate Kti implant or implants may be provided with a nut or nuts, these may be attached to the plate T-unong with a nut or nuts and implants. Multiple implants will work with root.

During this installation, the plate will be curved into a Haunonda O-shape. This will ensure that the stud end or nut is held back away from the chamber and has no tendency to lift away from the chamber during fastening. It would be fastened in the same manner as the belt securing the diaphragm.

The replaceable nut does not necessarily have to present a vertical surface relative to the diaphragm, but may have an undulating shape, for example with a tooth-shaped protrusion. This shape bends easily in one direction, although it is extremely difficult to bend in the opposite direction under the action of the rollers on the diaphragm. Either the flexibility of the replaceable pad or the flexibility of the padless shaped teeth, or both, allows solids up to a given size to pass through the index without damaging the pad. Make it.

During operation, there will be a pressure difference across the diaphragm, so on the inlet side of the inlet the pressure above the diaphragm, i.e. the pressure on the J-plane of the diaphragm away from the chamber, will be at the inlet. The pressure will be higher than the normal subatmospheric pressure in the world. On the other hand, the pressure above the diaphragm will be significantly lower than the pressure at the outlet. According to a further characteristic of the invention, it is proposed to provide a pressure-tight casing above the diaphragm and to pressurize the casing to a value between the inlet pressure and the outlet pressure. Here, the inlet pressure is represented by b and the outlet pressure is represented by C. When introduced into the casing, the pressure difference between the working side and the housing part is It can be seen that it will be the same on both the side and the exit side. Furthermore, assuming that there is either perfect sealing or equal leakage for the diaphragm on the bonde housing when deflected by the roller, all parts of the diaphragm will have the same pressure difference (even if the sign is opposite). ).

To facilitate sealing, the second housing part surface rMK facing the diaphragm may be provided with a ridge extending along the outer edge of the area through which the deflector passes.

The present invention! For easy understanding, specific examples will be described below with reference to the accompanying drawings.

The illustrated bonder includes an upper first housing part 10 and a lower second housing part 12 bolted thereto by an implant gel 13 and a nut 14.
The housing part 12 has a first port 17 which is clearly visible in FIG. It is provided with a central dish-shaped portion 15 having nine inner surfaces facing toward each other.

As can be seen more clearly in FIG. 1, the second housing part 12 cooperates with the first housing part on both sides, with the protruding fixing surface 19 normally - upwardly, i.e. on the surface 16.
Stay healthy by facing the same direction. Fixed surface 1 curved in the center
9 (see FIG. 2) terminate in a straight plane 20, each end extending above ports 17 and 18. Alternatively or in addition to this, the ninth @1 no.
The uzong has bands at both ends of the diaphragm. Further fixing surfaces 21.22 are fixed surfaces 19 and 20.
installed at right angles to the Portions 19.20, 21.2 which extend completely to the inner surface 16 and the outer portions of ports 17 and 18.
A fixing surface 21.22 extends between the I-t 17 and the part 18 such that there is a protruding fixing surface constituted by 2.

The first housing part 10 has a lower external fixing surface, which fixing surface is connected to the fixing surfaces 19, 20 of the second housing part 12.
, 21.22 are usually complementary to each other. The lower fixing surface of the housing part thus includes a straight fixing surface 20m and a curved fixing part 191 joined on each side by end fixing parts 21m, 22m. Here, the half value of the curvature of the curved portion 19m is that although the center of this curved portion coincides with the center of the curved portion 19, the surface 190 curvature is completely fixed and the surface 190 m is equal to the thickness of the diaphragm described below in Kojo WK. The radius is also small. The effect of this is on the parts 20, 20m, 21, 21m
, 22.

The tightening in the area of 22 m is due to the fact that the force occurs at approximately 45 degrees to the axis of the implanted gel 13, while in the central part the tightening occurs at right angles to this direction. Nevertheless, diaphragm compression is substantially uniform across the outer IIWJ. This has the purpose of ensuring that the edges of the diaphragm are not stretched by the passage of the rollers described below. The passage of the rollers produces a 47 DE action. Implant gelt 13
Very satisfactory results are obtained when the diaphragm is spaced substantially equidistantly along the sides of the diaphragm.

The diaphragm 24 is a molded member having a central dish-shaped portion 25 which has an arrangement similar to that given by the fixation surface and the surface 16, but where the portion corresponding to the surface 16 is 16 or raised from the surface 16 in the E direction. In FIG. 3, a preformed and unattached diaphragm is shown with nine fastening portions 26 along each side and fastening portions 27 along each end;
6 and 27 are spread over the entire station. Corrugated part 2 in the length direction
8r1 extends along both sides of the dish-shaped portion and is spaced inwardly from the fixing portion 26. The diaphragm includes longitudinal reinforcement 29, for example in the form of substantially non-stretchable fibers, which render the diaphragm substantially non-stretchable in the longitudinal direction. Another reinforcement 23 is provided just below the top surface of the diacrum. This OI sleeve stiffener may include four transverse elements as well as longitudinal elements. In practice, this further reinforcement is ias and extends across the entire width of the diaphragm. Flexion is greatly facilitated by this.

The concave surface of the center s25 is shaped to a radius that provides the required passage length when the diaphragm is distorted by the rollers.

Two brackets 30 on both sides of the second casing part 120
are attached, and each bracket is fixed with two spaced apart brackets using a magnetic melt 31. Only one gelt is shown in each figure. The racket has the shape of an angle iron having a vertical protrusion 32 and a horizontal protrusion 33, and the gel 31 passes through the protrusion 32. The holes in these protrusions can be made much larger than the gel to provide for the bracket to be slightly tilted vertically and horizontally. The bearing is attached to a stand 35 by a gel 34 in each horizontal projection 33ri. If desired, the bearing can be used to further vertically move the platform.
These bearings can be mounted on shims. The two bearings are on the stand! A child key groove 37 is provided to form a light bearing for the telescopic drive shaft 36. Two radial 7 lanzos 38 are welded to the shaft 36 (only one 7 lanzo can be seen).

Each flange 38 supports an annular mounting plate 39.

Mounted between the mounting plates 39 are roller shafts 40 arranged at four promontory angles, and bearings 41 for mounting four rollers 42 on these roller shafts.
is provided. Shaft 37.7 Lanzo 38. Mounting plate 3
9 and roller 42 constitute a rotor designated by the general reference numeral 45.

The force applied to the first mounting part 10-46
is held in place by an implant gel and nuts (not shown). A lubricant glue taper 47 is mounted on top 46 of the lubricant. In order to bring the roller 45 into contact with the roller 42 when it rotates, this riser 4 is...
A core 48 extending from the top of the housing 46 is provided.

Another method for applying lubricating oil to the outer surface of the roller is shown in FIG. is contacted again by roller 42. 1st
A ninth further arrangement for providing lubricating oil on the outer surface of roller 42 is shown in the figure. This arrangement forms an impregnation ring 50 through which the shaft 37 passes. The ring has a radius that allows the ring to contact the outer surface of the roller 42 at the point where the roller is directly below the shaft 37.

The arrangement of Ky17f is chosen such that the effective length of the upper surface of the diacrum is constant. ff1lli shown along the diaphragm between the fixed surfaces 21 and 21m on one side of the bonde and the adjacent roller 42;
When two rollers are in contact with the diaphragm,
The distance shown along the diaphragm from the adjacent roller to the next roller and this roller also at the other fixed surface 22, 22at and the O sum are independent of the position of the rotor and 11
It remains constant regardless of whether ten rollers or two rollers are in contact. This means that the lear 7 ram does not have to extend at all while the rollers are working. For this reason it is possible to include reinforcement in the length direction. This stiffener prevents the diaphragm from stretching and allows the diaphragm to deflect by the appropriate amount under the action of the rollers 42, although the nine stiffeners placed on the bias prevent excessive deformation. do. As the rotor 45 rotates, the telecompression section or closed telecompression chamber formed at the junction with the dial face [1g] moves from the inlet port 17 to the outlet port 18. Since there are at least three rollers 42, nine rollers 42 are formed in this way! A cell is always separated from at least one IC. Since the sum of the distances mentioned above is constant, the 10471 action can occur in an appropriate manner. It will be appreciated that before the closure created by one roller disappears, the next closure will be formed.

A thermistor device, designated by the general reference numeral 50 in FIGS. 1, 2 and 4, is mounted in a suitable manner on the pump. As can be seen in Figure 2 and Figure IJc4, the Zagedeno appetizer chair 50 is the first one (452) and the second (452). 53 and the third Chan

Denote the inlet pressure at 17 by b, the outlet pressure by C, and the casing pressure by a, with the pump inlet pressure increasing or decreasing and/or b! If the outlet pressure decreases or increases,
This causes the piston 51 to move up and down, respectively. The area difference between the piston rond 58 and the main part of the piston 51 is represented by d, and the area difference between the intermediate piston 51 and the upper flat part 59 is also represented by d, and the area difference between the intermediate piston 51 and the upper flat part 59 is represented by d.
If the total area of the top plane of is expressed as 2d, then
There will be a relationship. This ensures that the differential pressure across the diaphragm will always be substantially the same, even if of opposite sign.

As can be seen in FIG. 2, the curvature table WJ16 is slightly elongated so that there is a significant amount of overhang. The two dashed lines 60 and 61 are arranged at a mutual Kli angle. These two dashed lines are drawn so that the two adjacent rollers touch the diaphragm with the surface 16 on two sides at the same time.

As understood from @1IiJ, trough 16 is common O
It is integrated into surface 19 by two arcuate surfaces 64 and 65 with tangents 66 . This tangent 66 was placed at an angle of 40±5, which was found to be the best angle (
In Figure 5, which will be explained below, the corresponding angle is 30
is preferred). If the angle is too steep, it will tend to bow the diaphragm across the bottom corner of the trough, resulting in a relatively large inversion of the diaphragm from its original shape to a completely distorted tiger shape. This generates extremely high deflection stresses. If the angle is too shallow, this means that the pump requires a very wide housing. 6, which is exposed to the largest bending force and is extremely thinner than other parts of the diaphragm;
It may be noted that the flexure of the membrane can be improved by the part of the diaphragm indicated by 7, and in this way this part acts as an at, - = hinge.

FIG. M5 shows the lower portion of the modified structure or the upper surface portion of the second housing portion 120.

It will be appreciated that in this case the lower surface 70 curves upwardly at 71 towards the protrusion 72 which presents a cross-section consisting of a curve extending above the fixing surface 74. When the diaphragm is fixed in this way, the outermost part of the diaphragm is immobilized by the bolts passing through the holes in the diaphragm, but the diaphragm fixed together with the housing part is stretched to some extent laterally by the action of the protrusions. I am made to do so. This will reduce the possibility of longitudinal bulges occurring laterally and outwardly of the deflector roller, and it will also provide a barrier between the fixing surface and the delivery chamber to allow the diaphragm O to The modified pump shown in FIG. 6 includes a housing 100 whose internal shape is slightly modified, in other words slightly elongated. Enlarged cross-section 102 is indicated by 104 and allows for the introduction of a wrist arm. This /4 dot is surrounded by an elastic material of 5th grade and is surrounded by a partial annular delay in the center.

The shape of No. 5 is a shape with a radius of curvature as large as that of Uging 100. Therefore, the end of the male/four-piece material 104 surrounding the plate 105 is located in front of the central part of the arm joint. - contacting the Usong surface 102; When the nut 108 is tightened, the Kll-shaped plate slightly compresses to ensure that the end does not move during use.

If the material has sufficient elasticity, the /77'' housing not only overcomes the wear problem but also avoids damage from small hard solid materials compressing the material. If desired, the shape of the padless letterforms may be curved not in the direction opposite to the direction of travel of the rollers, but in the direction in front of the travel, and thus be able to accommodate material of The top surface of the four-rad 1040 may be provided with a padless tooth profile to enable solid material to be delivered by the diaphragm. and the position of a single deflector roller at an intermediate rotational position of the deflector assembly is shown in phantom.

FIG. 7 shows another structure of the device of the invention. In this case, belt ll0FiE'-li of la 42! The belt is fixed to the casing part 10 by a stock f111 so that the belt itself cannot move. The belt does not have to be fixed or for example diaphragm 0X
The -4 bolt, which may be fixed to the diaphragm 24 in the center of the -S, may be a simple belt or may be replaced by a toothed belt.

In this case the rollers 42 would be provided with cooperating protrusions; such a belt arrangement substantially eliminates any wear of the diaphragm by the deflector rollers.

FIG. 8 shows an O structure according to KFi, and shows an I ear 7 ram 24 in this case. This diaphragm is an upper plate-like body 12
5 and a lower flat plate-like body 126.

The plate-like bodies on the two sides are virtually aligned to form a plate-like structure.
They may be joined together or may be separate.

The materials of the two plates can be chosen to give various effects. For example, the upper plate can be of a hard material so as not to be abraded by the rollers, and can be practically centered in the width of the rollers. It can be made to exist only in the part O.

On the other hand, the lower plate 126F′i could be formed from a material that is flexible but not longitudinally extensible, flt
The nature of the surfaces or layers in contact with the body can be selected to provide the necessary mechanical, chemical and thermal conditions for the fluid by using optimal materials. on the other hand,
The material in contact with the rollers can be configured to provide the required wear resistance and mechanical properties. An intermediate layer may be provided, which serves to bond the other layers together and perhaps also to provide normal elasticity to the diaphragm 7 as a whole, thus making the delivery channel - Avoiding damage due to the passage of solids in the arm or changes in the diameter of the rollers of the rotor.

If the plates are not bonded, the bending-fatigue life of the LIA7 ram can be increased compared to a single layer with the same total thickness. Figures 9 and 10fiA show another structure,
This structure is similar to the structure shown in FIG. 1 in general, except that the bearing pedestal 135 is mounted on the subframe 136.

The sub-wafer 136 is rotatably attached to 137 on the lower part 171B. The other end of the St frame can be fixed with a wing nut 139. It is preferable that the wing nut is formed in the sub-shape and is tightly secured, so that when properly seated, it occupies the center of the sub-shape exactly. FIG. 9 also shows the possibility of providing a sedge ring 140. This sedge ring can be used to round off the subframe to pull it downwardly against a full stop position defining the correct relative alignment of the rotor and diaphragm when the wing nut 139 is loosened.

The preferred construction provides a secure fixation of the sub-frame, although other splitter devices may be suitably provided as well.

Deflector roller assembly! Another advantage can be obtained if the second housing part is mounted as a pivoting assembly. 4 mm can be used to initiate Kfi deflection in the pipe, after which the housing with the deflector roller can be mounted away from the turning axis so that the flow continues based on the original 11 of the siphon. If it is desired to stop the flow, the deflector assembly can be returned to the working position and attached to the turning shaft, and the deflector assembly will act as a stop pulp, after which the bonder can be removed. The flow can be restarted by actuation, and the siphon can be continued by again mounting the assembly m times away from the axis.

Figures 11A and 111 show ! of different shapes! Ear 7 ram 25' is shown. The shape of this iaphram is O
Although differences are noted, the diaphragm shape is generally similar to that shown in FIG. 3 and can be used in generally similar pump constructions.

Nine substantially equally spaced through holes, such as 150 and 151, are arranged in two rows along the lateral edge of the diaphragm 24'. Furthermore, the front edge of the diaphragm 24'O and the rear edge 11K
Although through holes such as 152m and 152b are provided,

To prevent the edges, especially the leading and trailing edges, from being pulled as the roller passes over the diaphragm.
These through holes may be engaged by implanted bolts or bolts extending between the fixation members. To aid in sealing, the through hole may be provided with an inner circumferential rib such as 153.
