Description

Tube pump

The present invention relates to a tube pump, and more particularly, it is possible to stably maintain the transfer efficiency of the fluid with minimal load by the left and right swing method instead of the wave motion caused by the lifting and lowering of the working rod operated to transfer the fluid. It is about a tube pump that can be maximized.

In general, a pump that transfers a highly viscous fluid is used for a low speed and high viscosity fluid transfer, and a swing pump or swash plate pump capable of obtaining a high head is used. However, such a swing pump or swash plate pump causes pulsation. As a result, the driving is not stable and the feeding efficiency is also low.

Accordingly, a tube pump (Tube Pump) having the above-mentioned disadvantages of pulsation prevention and high transfer efficiency is used, and the tube pump has a technical configuration of a method of transferring fluid by continuously changing a volume inside the tube.

In other words, the principle of operation of the tube pump is to transfer the fluid by the wave movement along the lifting in the axial longitudinal direction using the tube.

In the prior art of the tube pump to which the above operating principle is applied, Republic of Korea Utility Model Publication No. 20-0174564 (hereinafter referred to as 'prior art document 1'), Republic of Korea Registered Utility Model Publication No. 20-0221537 (hereinafter 'preceding' Technical Document 2 '), Republic of Korea Utility Model Publication No. 20-0401775 (hereinafter referred to as' prior art document 3') and Republic of Korea Patent Publication No. 10-2001-0039807 (hereinafter referred to as' prior art document 4 ') It was posted in

The technical configuration of the above-described pipe pumps disclosed in the prior art documents 1 to 4 is a drive shaft with a plurality of eccentric cams are mounted at equal intervals to repeat the ascending and descending position of the top dead center in the same direction as the direction of the fluid and the drive shaft A fixed shaft positioned in parallel with the tube, a tube having a relatively larger diameter than that of the fixed shaft, and a tube inserted into the outer surface of the fixed shaft, and a cam insertion hole into which the eccentric cams are inserted. In the upper portion is formed a tube insertion vertical hole is inserted into the outer surface of the tube and has a technical configuration consisting of a plurality of operating rods to sequentially move up and down in conjunction with the rotation of the eccentric cams.

In addition, the upper and lower sides of the housing are formed so that the fixed shaft and the tube chamber on which the tube is mounted and the operating chamber on which the driving shaft is mounted are connected to each other.

Both ends of are fixed.

In addition, both sides of the operating chamber is fixed to the housing with a mounting bracket is formed in the mounting hole and the drive shaft is mounted to the mounting hole in the lateral direction through which the plurality of eccentric cams are mounted.

On the other hand, the upper side of the tube chamber is equipped with an openable cover to facilitate maintenance, the outer side of the opening is mounted to the connection bracket to prevent the separation of the bracket and the fluid pipe is connected, the middle of the fixed shaft The tube contact portion is formed in the expanded diameter and the inclined portion is formed on both sides of the tube contact portion to facilitate the flow of the fluid.

And the brackets mounted on both sides of the tube chamber is formed in the center and comprises a cap fixed to both ends of the fixed shaft and a mounting ring formed integrally through the rib on the periphery of the cap fixed to both ends of the tube .

Accordingly, when the tube pump operates the drive unit connected to the drive shaft mounted on the lower portion of the housing, the top dead center positions of the plurality of eccentric cams are repeatedly raised and lowered sequentially according to the rotation of the drive shaft, thereby operating rods mounted on the eccentric cam. Ascending and repeating as the position of is changed.

Therefore, the tube is bent like a wave movement about the fixed shaft through the repositioning of the working rod repeatedly, so that the fluid flows from one side to the other side. In addition, when the fluid is conveyed, the compressive force of the tube is generated, so that the conveying pressure is generated in the fluid passing through the tube.

And a phenomenon in which the fluid is pushed by the reaction force in a direction opposite to the direction in which the fluid is operated. As a result, the flow noise as well as the fluid is not smoothly transferred.

In addition, a large amount of eccentricity of the eccentric cam is generated in the tube between the working rods located at both ends and the fixed shaft fixed to the brackets on both sides, and as the fatigue accumulates at both ends of the tube, a short time is elapsed. Along with abrasion, there was a problem that eventually broke.

Above all, the driving shaft is equipped with a plurality of operating rods in the process of raising and lowering all the loads are applied to the driving shaft to generate a large load, as well as a large number of friction surfaces with the plurality of operating rods due to the lifting, the drive shaft is worn down thinner Has This in turn has a problem that the pumping amount is not constant in the process of transporting the fluid.

In particular, when attempting to transfer an electrolyte or the like, which is a highly viscous fluid, sparks may occur due to an impact caused by abrasion of the drive shaft, which also has the disadvantage of an explosion risk.

In order to improve the above problems, the diameter of the drive shaft must be increased, which in turn provides a cause for the overall volume of the tube pump to increase.

As shown in the drawing, the tube pump 1 is used to transfer fluid by continuously changing the volume inside the tube so as to be suitable for low speed and high viscosity fluid transfer and to have high transfer efficiency with pulsation prevention.

The present invention is intended to maximize the transfer efficiency of the fluid while stable operation with minimal load by the left and right swing method rather than the wave movement by the lifting and lowering of the working rod operated to transfer the fluid.

Tube pump (1) according to the present invention includes a main body housing (10) having a cover (12) provided on the upper surface to be opened by a conventional bolting or clamp, etc .; A support shaft 20 provided at both ends of the inner housing lower portion of the body housing 10 to be fixed by a conventional fixing member; Both ends are rotatably provided inside the upper body housing 10 of the support shaft 20, and one end thereof is protruded from the body housing 10 to be connected to a power means 30A composed of a conventional motor and a power transmission unit. The drive shaft 30 includes a plurality of eccentric cams 32 mounted at equal intervals. At this time, the eccentric cam mounted on the drive shaft is the eccentric cam mounted in the pumping section except for the eccentric cam located at both ends, the eccentric amount is uniformly formed and equally assembled according to the divided angle.

In addition, the fixed shaft 40 is fixed to the inner end of the upper body housing 10 of the drive shaft 30, the tube 42 having a flexibility to the outer surface is fixed with the tube 42 at both ends; And a lower portion of the support shaft 20 is rotatably inserted into the support shaft 20 by a common bearing, and the plurality of eccentric cams 32 are inserted together with the respective bearings 32A on the upper side of the support shaft 20. It is fixed and inserted into the outer surface of the tube 42 on the upper side of the eccentric cam 32 to transfer the fluid while swinging left and right sequentially from the support shaft 20 with the rotation of the eccentric cams as a starting point. It includes a plurality of operating rod (50).

Reference numeral 100 denotes a support frame to which the main body housing is fixed in a conventional manner, and the support frame is preferably provided with a power means, and a control panel for controlling whether or not the power means is driven.

As described above, the actuating rod of the present invention is inserted into the tube by the amount of eccentricity of the eccentric cams from the lower portion of the support shaft fixed by the eccentric cams mounted on the drive shaft rotated by the power means. The upper part swings left and right.

The fluid in the tube thereby transfers the fluid introduced from one side of the tube to the opposite side by contact with the tube by means of an actuating rod that swings from side to side, i.e. the top of the actuation rod inserted into the outer surface of the tube swings from side to side. Let's go.

Here, since the lower portion of the operation rod is supported by the support shaft, the load applied from the plurality of operation rods is supported by the support rod. Accordingly, all loads of the conventional plurality of operating rods are applied to the driving shaft to be rotated, so that the load is greatly generated, as well as the friction surfaces with the plurality of operating rods due to the lifting and lowering do not cause the problem of thinning of the driving shaft.

Moreover, the driving shaft of the present invention can swing the operating rod from side to side even with a small load, that is, the lower side of the operating rod is supported by the support shaft, so that the operating rod oscillating from side to side to transfer the fluid has a small power. It has a condition that the fluctuation of the right and left can be made smoothly.

In particular, the plurality of eccentric cams mounted in the pumping section are eccentric amount is formed uniformly and equally assembled according to the divided angle, the fluid conveyed as the flow to the left and right of the working rod is constantly fluctuated only to the left and right by the eccentric amount The pumping amount of also has a condition that can be kept constant at all times.

As a result, the driving is performed with the least power and the load is minimized, thereby maximizing the transport efficiency of the fluid.

In particular, since the left and right swings of the working rod are smoothly performed with minimal load and small power, the friction loss can be minimized, that is, the bearing is interposed between the working rod and the eccentric cam, and also between the support shafts. Accordingly, frictional losses can be minimized when the working rod swings from side to side. This, in turn, prevents abrasion and the like from occurring, and has a condition that can prevent the shock caused by the tolerance caused by the abrasion and the noise caused by it. There is also a requirement to increase the reliability of the product.

In addition, the operating rod oscillated from side to side swings only by the amount of the eccentric of the eccentric cam, so that the impact caused by the conventional lifting and lowering does not occur. There is also a condition that can be transported stably.

On the other hand, the eccentric cam 32 further includes a smaller amount of eccentricity toward both ends except for a pumping section, which is an intermediate portion of the drive shaft 30.

In other words, by reducing the amount of eccentricity toward both ends of the drive shaft except for the intermediate pumping section of the drive shaft, the amount of eccentricity between the end of the drive shaft and both ends of the actuating rod is reduced, so that the fatigue stress in the tube located therein is reduced. ) To reduce the wear and tear caused by the wear of the tube. As a result, the tube can be used for a longer period of time.

In addition, respective openings 12 are formed at both sides of the body housing 10 at which both ends of the fixed shaft 40 are fixed, and each of the openings 12 is provided with a bracket 44 through which fluid passes. Both ends of the fixed shaft 40 and both ends of the tube 42 inserted into the outer surface of the fixed shaft 40 are fixed to the center and the periphery of the bracket 44, On the outside, it is preferable that a connection bracket 46 is connected to a conventional fluid pipe (not shown) to be transported while preventing separation of the bracket 44.

In addition, the bracket 44 is formed at the center of the cap 44A to which both ends of the fixed shaft 40 is fixed, and integrally formed through the rib on the periphery of the cap 44A to both ends of the tube 42. It is preferable that the configuration comprises a pair of mounting ring 44B is fixed.

In addition, an airtight flange 42A having a diameter larger than the diameter of the tube is integrally formed at both ends of the tube 42, and the airtight flange 42A is formed at each end of the fixed shaft 40. Together on the bracket 44.

In addition, a tube contact portion 40A having an enlarged diameter is formed in the middle of the fixed shaft 40, and both sides of the tube contact portion 40A have respective inclinations having a diameter smaller than that of the tube contact portion 40A. By forming the portion 40B, it is preferable to smoothly flow the fluid by the left and right swing of the operating rod. That is, the inclined portion is a portion in which the fluid is introduced and discharged, and the tube contact portion is uniformly pressurized while the upper portion into which the tube of the operation rod is inserted is oscillated from side to side in order to make the flow of the fluid uniform and uniform. It can be.

In addition, respective fixing brackets 16 having mounting holes 14 on which both ends of the driving shaft 30 are mounted are mounted at both sides of the body housing 10 on which both ends of the driving shaft 30 are fixed. The hole 14 includes a bearing to which both ends of the drive shaft 30 to which the eccentric cams are mounted are mounted.

Therefore, the overall rotation of the drive shaft can also be stably rotated without fluidity, which is one of the factors that can make the fluid transfer uniformly.

On the other hand, the plurality of operating rod 50 of the present invention is operated to directly transfer the fluid, the specific technical configuration has a technical configuration as shown in FIG.

The actuating rod 50 includes a main body 50A having a plate shape having a predetermined thickness and width; A mounting hole 52 inserted into and fixed to a support shaft 20 fixed to an inner lower portion of a main body housing 10 of a tube pump 1 that is a fixed end in a lower portion of the main body 50A;

A plurality of eccentric cams 32 mounted at equal intervals by a drive shaft 30 provided on the inner surface of the body housing 10 of the tube pump 1 to be rotated by a power means on the mounting hole 52, respectively. A cam insertion hole 54 inserted into the bearing 32A of the cam; And a tube insertion hole inserted into an outer surface of the tube 42 that is flexibly covered with an outer surface of the fixed shaft 40 so that the fluid can be transferred to the upper upper portion of the cam insertion hole 54 in a conventional manner. 56);

Tube insertion long hole 56 is preferably formed in an elliptical shape that corresponds to the range in which the eccentric cam is rotated for smooth rocking when the upper portion of the operating rod swings from side to side by the eccentric cam. Accordingly, when the operating rod swings left and right, the contact with the tube is smoothly performed, so that the fluid can be smoothly transferred.

The operating rod of the present invention configured as described above is a tube by the amount of eccentricity of the plurality of eccentric cams starting from a mounting hole inserted and fixed to the lower support shaft by a plurality of eccentric cams mounted on the drive shaft rotated by the power means The upper portion of the tube insertion hole is inserted is rocked from side to side.

Therefore, the fluid in the tube is bent left and right by the actuating rod oscillating from side to side, that is, the upper tube insertion hole of the actuating rod inserted into the outer surface of the tube is oscillated from side to side, and one side of the tube is bent. The fluid flowed in from is transferred to the opposite side.

Accordingly, the support shaft does not generate much load as compared with lifting the entire operation rod, that is, the mounting hole formed in the lower portion of the operation rod of the present invention is inserted and fixed on the support shaft to be supported in a fixed end shape as well as swinging from side to side. May be minimized.

In addition, the oscillation of the working rod to the left and right is also oscillated to the left and right only by the eccentric amount of the eccentric cam by the rotation of the drive shaft with the minimum power, that is, the lower end is supported and fixed in the form of a fixed end by the mounting hole as the support shaft The fluctuations to the left and right can be made smoothly with minimal power.

As a result, the fluid transfer in the tube can be uniformly and uniformly pumped, thereby having a condition for maximizing the transfer efficiency.

Thus, by moving the operating rod provided in the tube pump of the present invention to the left and right by a simple principle to transfer the fluid, it is possible to maximize the transfer efficiency of the fluid as well as to smoothly drive with a minimum power and load. As a result, high reliability can be obtained.

On the other hand, it is preferable that each ball receiving groove (50B) that can be accommodated each ball (B) is formed on both sides of the front and rear of the main body (50A).

That is, the operation of the operating rod has a condition that can minimize the frictional loss between the operating rod by each ball interposed between the operation receiving the ball receiving groove between the operating rod. In particular, the phenomenon in which the fluid is pushed by the reaction force in the opposite direction to be transported can also be minimized due to the reduction of the frictional loss, which also has the condition to minimize the flow noise with water.

FIG. 6 is a perspective view of a part of an open state for explaining another embodiment of the present invention, and FIG. 7 is a flowchart illustrating a state in which an open part of FIG. 6 is closed.

In the above configuration as shown, it provides a technical configuration that can be mounted more simply and conveniently to the tube covered with flexibility to the outer surface of the fixed shaft by the tube insertion hole of the working rod.

The upper portion of the main body 50A is formed in a structure that opens and closes relative to the transverse direction of the tube insertion hole 56, and the fixing clamp 60 is rotatable to the rotated portion while one end is rotatably fixed by a conventional pin coupling or the like. ) Is provided with an upper body 50A-1, and one end is rotatably fixed to the opposite side on which the fixing clamp 60 is formed by a conventional pin coupling, so as to cover the upper surface of the upper body 50A. It further comprises a fixing wire 70 fixed by the fixing clamp 60. The fixing wire is applied to any known technical configuration capable of fixing or opening the opening and closing the upper body in addition to the above structure as part of the conventional locking means to allow the upper body to be opened or closed with the fixing clamp. It is okay.

Therefore, the tube that is covered with the tube insertion hole to be flexible to the outer side of the fixed shaft is opened by the upper body to be seated with the tube insertion hole, and the upper body is closed again to fix it. to provide. In addition, as the upper body is opened and closed, the maintenance of the tube or the fixed shaft also has the convenience that can be made quickly in a short time without any hassle.

In addition, the tube insertion hole 56 is fixed to the packing 80 of the form corresponding to the tube insertion hole 66 is fixed. Coupling of the packing is made by grooves and protrusions of a conventional corresponding form.

In addition, the packing 80 includes an integral form or a vertically divided form corresponding to the tube insertion hole. That is, when the packing is formed integrally, the tube should be inserted from one side, but the tube is inserted into the upper and lower parts, and the tube insertion hole is formed in the upper body and the tube insertion hole is formed in the lower body. Combination has the convenience of using more efficiently.

On the other hand, both sides of the inner surface of the cam insertion hole 54 further includes a protruding respective support protrusion 54A for supporting both sides of the bearing 32A coupled to the eccentric cam 32 is provided. That is, the bearing is coupled to the outer surface of the eccentric cam, when the bearing is inserted into the cam insertion hole to fix the outer ring of the bearing instead of fixing the entire outer ring of the bearing, thereby increasing the mounting efficiency further It is desirable to be able to.

Therefore, mounting to the cam insertion hole also has a condition that can be made more convenient, simple and easy.
