Description

Pump

The present invention relates to a pump capable of efficiently pumping a fluid, such as sludge and manure, which contains a large amount of air, liquid, or water, is viscous, and includes various foreign substances, such as fibers, wires, or chopsticks.

The transfer or compression of the fluid, ie gas or liquid, is via a pump. A pump is a device that transports a fluid (gas or liquid) through a pipe by a pressure action, or pumps a fluid in a low pressure container into a high pressure container through a pipe. ), But in the present design, collectively referred to as a pump.

The pump can typically be classified into a reciprocating pump in which a piston or a flanger reciprocates and pumps the cylinder, and a rotary pump in which a piston acting as a piston of the pump performs a piston action to the rotor.

By the way, the reciprocating pump is pumped while the delivery valve and the suction valve are opened and closed alternately to inhale and discharge the liquid, and a single cylinder and a valve set are called single-acting pumps. In this type, pulsation of water occurs, and a combination of several double-acting bumps, differential pumps, or single-acting pumps must be used to average the amount of water. But pulsations still have the disadvantage. In addition, since a valve is required to prevent the back flow of the fluid, the flow of the fluid is interrupted, thereby reducing the efficiency of the pump.

Rotary pumps are also referred to as rotary pumps, which are suitable for low flow and high pressure lifts, are simple in structure and easy to handle. Since it continues to carry the fluid so that the discharge amount does not pulsate like a normal reciprocating pump, there is a disadvantage that the efficiency is lower than reciprocating pump.

On the other hand, these pumps have a problem in pumping viscous fluids such as non-flowable materials, solids, ultra high concentrations, ultra high viscosity liquids, and high concentration sludge which are considered to be difficult to transport by pumps in the industry. .

That is, in the general process of wastewater (livestock manure) treatment, the biologically decomposed treated water is transferred to the settling tank through a bioreactor composed of an anaerobic tank, an aerobic tank, etc., the supernatant is recovered, and some of the precipitated sludge is recovered. It is returned to the bioreactor to maintain the proper concentration of microorganisms in the bioreactor, and the remaining excess sludge is concentrated through the sludge thickening tank, collected, dehydrated through the dehydration tank, and landfilled or incinerated. At this time, the collection of the sludge is collected using a separate collection means, that is, a pump.

However, the sludge is a highly viscous cake state, and because it contains fibers and other foreign materials, such as wire, chopsticks and gloves, there are many difficulties in pumping them. Until now, the centrifugal pump was mainly used to pump the sludge, but various problems such as the above were often caught in the pump, causing frequent failure of the pump.

The present invention focuses on the advantages of the reciprocating pump and the rotary pump to provide a pump with a small pumping capacity, high pulsation, noiseless, and quantitative transfer capability.

Another object of the present invention is to provide a pump capable of pumping highly viscous liquids such as sludge, which contains a large amount of water and has high viscosity, and contains various foreign substances, such as sulphate, wire or chopsticks, without failure. It is.

Another object of the present invention is to be able to vary the capacity of the pump.

The present invention for achieving the above object,

A rotor having a plurality of cylinders including pistons in the same rotation radius in parallel at regular intervals and having a shaft at a rear center portion thereof;

A head casing that is hermetically covered at the tip of the rotor to be coupled to the rotor so as to be rotatable, and has a suction and discharge space therein and a suction and discharge port adjacent to suck and discharge fluid into the suction and discharge space;

The material is rotated in the state refracted to the shaft at the rear side of the rotor and is hinged to the piston and the piston rod of each cylinder at the circumference, the bottom dead center at the end of the suction space of the cylinder head and the top of the discharge space starting point A piston operating plate inclined to have a point,

And a drive motor for rotating the piston operating plate at the rear side of the piston operating plate.

In addition, the present invention is achieved by having a rotary blade that is joined to the front end surface of the rotor in the cross-sectional shape of the rotor, and a fixed blade attached to the suction and delivery space inside the head casing facing the rotary blade. .

The rotor 10 has a circumferential shape in which a shaft hole 12 is formed in a central portion as shown in FIGS. 3A and 3B, and a plurality of cylinders 14 are fixed at the same rotation radius around the shaft hole 12. It is formed parallel to the axial direction at intervals.

In addition, a piston 16 is installed in each of the cylinders 14, and a plurality of rings 162 and 163 are coupled to the inner circumference of the piston 16 to maintain airtightness with the inner wall of the cylinder 14. The packing 164 is installed in front and rear of the 162 and 163. And the piston head 166 is fastened to the front by a fixed bolt 168.

The head casing 20 has a receiving portion 22 into which the front end portion of the rotor 10 is inserted, as shown in FIGS. 4A and 4B. A plurality of seals (222, 223) (seal) for retaining airtightness are inserted around the receiving portion (22) while maintaining a smooth rotation of the rotor (10), and the thread is fixed to the outer end of the seal (223) of the outer portion A flange 224 is formed and bolted to the head casing 20. In addition, a suction space 226 and a discharge space 227 are provided adjacent to the inside of the head casing 20, and a suction port 228 communicating with the suction and discharge spaces 226 and 227 of the fluid in front thereof. And an outlet 229 are formed. In the center portion, a shaft 24 is inserted into the shaft hole 12 of the rotor 10 to support rotation of the rotor 10. And the head casing 20 is a support 26 is installed in the lower portion is firmly bolted to the base (B).

The piston operating plate 30 is installed to be inclined at a position spaced apart from the rear side of the rotor 10 as shown in Figure 5a, 5b, the connecting protrusions 32 are provided in the number of the piston 16 around the front have. In addition, the rotary shaft 40 is coupled to the rear center portion of the rotor 10, the end of the rotary shaft 40 is a material joint 42 that is capable of rotating in a state bent with the center of the piston operating plate 30, that is, universal Is coupled through the joint, the connecting projection 32 of the circumference is connected to the piston 16 through the piston rod 18. At this time, the piston rod 18 has three bodies, the first and second connection sockets 184 and 185 which are hinged to the rear side of the piston 16 and the connecting projection 32 of the piston operating plate 30, Consists of a connecting rod 182 connected between the first and second connecting sockets (184, 185). Female threads are formed at the free ends of the first and second connection sockets 184 and 185, and male threads are formed at both ends of the connecting rod 182, and both ends thereof are formed with female threads of the first and second connection sockets 184 and 185. It is screwed and eventually has a structure that can be adjusted in length.

In particular, the piston operating plate 30 is inclined so that the piston 16 has a bottom dead center at the end of the suction space 226 of the head casing 20 and a top dead center at the start point of the delivery space 227. In other words, the bottom dead center when the distance between the rotor 10 and the piston operating plate 30 is maximized is positioned at the beginning of the delivery space, and the distance between the rotor 10 and the piston operating plate 30. When the top close to the maximum dead center is to be located at the beginning of the suction space (226).

And the rear side of the piston operating plate 30 is provided with a drive motor 50 for rotating the piston operating plate 30, the lower portion of the drive motor 50 is coupled to the base (B) the drive motor It has the support part 52 which supports 50, and it is couple | bonded with this support part 52 so that angle adjustment is possible. That is, the support portion 52 has an angle adjustment base 522 formed with a plurality of arc-shaped angle adjustment grooves 524 and 525 having concentric shafts of the material joint 42, and a bracket 523 beneath the driving motor 50. The bracket 523 is bolted to the angle adjusting grooves 525 and 525 of the angle adjusting base 522 so that the driving motor 50 is angle-adjusted within the angle adjusting grooves 524 and 525 when necessary.

In such a pump, an important configuration is the structure of a blade for cutting foreign matter. The blade is provided opposite to the front end surface of the rotor 10 and the inside of the head casing 20, the blade is installed on the front end surface of the rotor 10 to the rotary blade 60, and the head casing 20 The blade to be installed is called fixed blade (70).

The rotary blade 60 installed on the front end surface of the rotor 10 is formed individually by each cylinder 14, the shape of the cylinder having the same hole as each cylinder 14 of the rotor 10, each cylinder Bolting to the front of the (14) is enough, but for the ease of assembly is a one-piece having a cross-sectional shape of the rotor 10 is padded to match each cylinder (14) on the front of the rotor (10) Bolted together.

In addition, the fixed blade 70 is firmly installed at the boundary of the suction and delivery space as shown in Figure 4c.

Looking at the operation of the pump of the present invention having such a configuration as follows.

When operating the drive motor 50, the drive motor 50 is rotated while rotating the piston drive plate inclined, the rotor 10 connected to the rotary shaft 40 and the material joint 42 is rotated. The minimum contact point and the maximum circle contact point are generated between the piston operating plate 30 whose shaft is deflected by the rotation of the rotor 10, and the piston rod 18 moves the piston 16 forward and backward by the distance difference. Let's do it.

In particular, when the piston 16 is retracted, since a negative pressure is generated inside the cylinder 14, the fluid is sucked into the suction space 226 through the inlet 228, and the cylinder 14 is moved forward when the piston 16 is advanced. Since positive pressure is generated inside the fluid, the fluid is discharged to the discharge space 227 and the discharge port 229.

In more detail, the negative pressure is applied at the entry portion of the suction space 226 in the head casing 20 and the positive pressure is applied at the entry portion of the delivery space 227.

When the piston operating plate 30 and the rotor 10 rotate by the inclination angle of the piece cylinder operating plate, the suction port 228 and the suction space of the head casing 20 by the sequential advancing operation of the respective pistons 16. Fluid is continuously sucked into the part 226, and fluid is continuously discharged to the outlet 229 and the outlet space 227 of the head casing 20.

If you want to increase or decrease the pumping capacity of the fluid, that is, to change the pumping capacity, adjust the inclination angle of the piston operating plate 30 through the angle adjusting device installed in the lower part of the driving motor 50 to adjust the pumping capacity. Can be varied. That is, when it is desired to increase the pumping capacity of the fluid, when the driving motor 50 is lowered by unscrewing the bolt coupled to the support 52, the piston is rotated based on the joint 42. The angle of inclination also becomes large. Because of this inclination angle, the distance between the top dead center and the bottom dead center of the piston 16 is increased, resulting in a long stroke of the piston 16. Therefore, the suction efficiency is further improved.

However, it must be made within the limit angle of refraction of the material joint 42.

If you want to reduce the suction capacity of the fluid by reducing the inclination angle of the piston operating plate 30 a little, lift the operating plate from the inclined angle adjusting groove and then tighten the bolt to fix the angle of the driving motor 50 to an angle close to horizontal. In addition, since the angle of the piston operating plate 30 that moves integrally with the same is also changed, it is possible to reduce the pumping capacity of the fluid as desired.

On the other hand, while pumping the fluid is attracted high-viscosity fluid, that is, metal foreign matter, such as fiber, wire, chopsticks, etc. contained in the fluid such as sludge, once the suction is drawn into the cylinder 14, the rear end that is not sucked The inlet portion of the cylinder 14 is caught or caught. At this time, the foreign matter is rotated together with the cylinder 14 and formed inside the head casing 20, that is, the fixed blade 70 formed at the boundary of the suction and discharge ports 228, 229 and the front of the rotor 10 It is to be cut by the rotary blade (60). Therefore, the pump operates smoothly because it does not interfere with the operation of the fluid flowing in and out.

The pump of the present invention is designed to transfer non-flowing chemicals, transfer of semi-solid printing ink or varnish, dehydration cake, co-ting color transfer, transfer of juice ground or coffee grounds, transfer of apricots containing apricots, and chopped in fish farms. It can be used for feeding meat, transporting food waste in restaurants and homes.

The present invention has a high pumping effect because it is configured to continuously suck and discharge fluid by a plurality of pistons advancing and retracted from each cylinder around the rotor by a piston operating plate rotated in an inclined state by the drive motor. Since several pistons continuously suck and discharge fluid in one suction space and a discharge space, the fluid can be discharged with no pulsation, thereby minimizing the noise of the pump and enabling the pumping of a fixed amount.

At the same time, fixed and rotary blades are formed between the inside of the head casing and the rotor, so that even if foreign substances such as metal or fiber are attracted, they can be cut and sent out with the fluid, so that various foreign substances, such as fiber, wire or chopsticks, etc. Even high-viscosity fluids, such as sludge containing the same metals, have the effect of pumping without failure.

In addition, there is an advantage that does not cause a malfunction even if air is introduced with the liquid on the suction side.

In addition, the pump of the present invention having such an effect is used in various industries such as food, wastewater treatment plant, medicine, cosmetics, paint, paper, chemical, ceramics, civil construction, fine chemical, agriculture, fishery, animal husbandry, and fisheries. It can be used widely.
