Description

Vortex impurity pump

Technical Field

The utility model relates to a vortex trash pump, vortex trash pump are multi-functional products, can carry from the running water to the various different media of industry liquid, are adapted to different temperature flow and pressure range, applicable in the trade of difference, the waste liquid pump sending that especially the machining trade produced.

Background

Industrial waste water produced in the field of machining needs to be pumped with a vortex impurity pump to a filtering device for reprocessing or treated liquid needs to be delivered to a machine tool. Existing vortex trash pumps suffer from a number of disadvantages, such as: firstly, the cavitation resistance is poor, and the friction loss between the liquid and the liquid is large; secondly, the internal structure of the cavity in the pump is not smooth, so that the liquid is prevented from flowing out; thirdly, the shaft coupling is complex to process, poor in coaxiality, serious in rotation abrasion, easy to damage a motor and high in noise; and fourthly, the lift and the flow are smaller under the condition of the same motor power.

Disclosure of Invention

The utility model aims to improve the weak point that exists among the prior art, provide a reasonable in design, simple structure's vortex trash pump.

The technical scheme of the utility model is that: the vortex impurity pump is characterized in that an elastic coupling is arranged at the joint of the connecting shaft and a motor shaft, one end of the connecting shaft is connected with the motor shaft through the elastic coupling, and the cross section of an internal cavity channel of the cavity is in an involute unfolding shape from a central shaft outwards.

In order to reduce the friction between the liquid and the impeller, the blades on the impeller are designed into arc-shaped blades, and the impeller flow channel is arc-shaped.

The utility model discloses utilized the principle of gradually bursting at the seams with cavity inner structure, made the water outlet flow way enlarge gradually, and the runner is smooth and easy, hinders for a short time, in addition designs into the blade of arc form, makes whole impeller runner be the arc, is favorable to very much having the liquid of impurity to discharge from great delivery port department, the pump body that has significantly reduced and takes the friction between the impurity liquid. In addition, the motor shaft is connected with the connecting shaft through the elastic coupling, so that the motor shaft rotates stably during working, the service life of the motor is long, and the noise is low. Compared with the prior art, the utility model relates to a rationally, simple structure, it is smooth and easy to have the runner, and wearing and tearing are few, noiselessness, dependable performance, low power dissipation, longe-lived, a great deal of advantages such as maintenance convenience.

The present invention will be explained in detail with reference to the drawings and examples.

The drawings illustrate:

the device comprises a motor 1, an elastic coupling 2, a connecting shaft 3, a connecting body 4, a cavity 5, an impeller 6, a mounting plate 8, a water inlet 9 and a water outlet 10.

Detailed Description

Referring to fig. 1, the vortex impurity pump is installed below a container panel by taking a mounting plate 8 as a boundary, a motor 1 is installed above the mounting plate 8, a connecting body 4 is installed below the mounting plate, the other end of the connecting body 4 is a cavity 5 of the pump, the cavity 5 is cast as a whole, a water inlet 9 and a water outlet 10 are respectively arranged on the bottom and the side wall of the cavity, the inner surface of the cavity is smooth, the cross section of a cavity channel is in an involute unfolding shape from a central shaft outwards (see fig. 2 and 3), a connecting shaft 3 is arranged in the connecting body 4, one end of the connecting shaft 3 is connected with a motor shaft of the motor 1 through an elastic coupling 2, and the other end of the connecting shaft.

The working principle is as follows: liquid enters the cavity 5 from the water inlet 9, the impeller 6 rotates at high speed under the drive of the motor, a strong vortex is formed in the cavity 5, and the liquid and impurities mixed in the liquid are directly thrown out from the water outlet 10 under the drive of centrifugal motion. Because the cavity structure utilizes the involute principle, the water outlet flow channel of the cavity structure is gradually enlarged and has small obstruction, and therefore, the liquid with impurities can be completely discharged when running to the larger water outlet 10.

In order to reduce the friction between the liquid and the impeller, the blades on the impeller 6 are preferably designed into arc-shaped blades, as shown in fig. 4, the arc-shaped blades are connected with the blade disc in a curve manner, so that the whole impeller flow channel is arc-shaped, when the impeller stirs the liquid in the cavity by rotating at a high speed, the impeller flow channel is matched with the vortex formed when the liquid is stirred in the cavity, the friction between the liquid (impurities) and the impeller is reduced, the blades are not required to be connected with the central shaft of the impeller, a gap is reserved between the blades and the central shaft of the impeller, the obstruction is reduced, the liquid flow is facilitated.

In order to adjust the coaxiality between the motor shaft and the connecting shaft and reduce noise, the connection mode of the motor shaft and the connecting shaft 3 of the vortex impurity pump is designed to be connected by inserting an elastic coupling 2, and the connection mode is shown in figure 1. Therefore, the motor shaft rotates stably during working, the service life of the motor is long, and the noise is low.

The utility model discloses be suitable for the transport of industrial waste water such as lathe, car, bearing, steel rolling to and be arranged in river bed treatment, food, chemical industry, trades such as papermaking river bed mud, liquid food, papermaking paper pulp etc. to promote the transport, can use with various filtration equipment and solitary lifting means are supporting.
