RU214573U1 - Pontoon pump for homogenization and transfer of liquid organic fertilizers - Google Patents

Abstract

The utility model relates to devices for homogenization and pumping of manure from the lagoons of livestock complexes. The pontoon pump for homogenizing and pumping liquid organic fertilizers contains a conveying auger connected to a drive mechanism mounted on a shaft and enclosed in a casing, connected to a grinding and mixing working body, a receiving chamber communicated with the cavity of the casing of the transporting auger, and the grinding and mixing working body is made in in the form of trapezoidal blades with longitudinal holes fixed on the shaft of the conveying auger. In addition, the upper part of the casing of the conveying auger is connected to the injection chamber, inside which the blades are fixed coaxially to the shaft of the conveying auger. Moreover, on the pontoon, a vertical stability bushing is rigidly fixed coaxially to the conveying auger, the inner surface of which is freely mounted on the conveying auger body. The technical result consists in increasing the efficiency of the pontoon pump due to the stability of the vertical position of the conveying auger during homogenization when pumping liquid fertilizers from the lagoons of livestock complexes.

Description

The proposed utility model relates to devices for homogenization and pumping of manure from the lagoons of livestock complexes.

Known pumping unit containing a floating structure, made with the possibility of holding on the surface of the reservoir and serving as a support for the pump housing, including immersed in the liquid inlet, outlet and fluid injection device. The injection device is placed in the fluid flow between the inlet and outlet holes, has an elongated shaft and forms an axial pump with the housing. The passage of the liquid of the pump, at least partially coincides with the longitudinal axis of the pump housing. The shaft is at least partially surrounded by the cage. During operation and switching on of the pumping unit, at least the outlet is arranged in a predetermined, preferably horizontal, orientation. The power unit, located based on a floating structure, is connected to a liquid injection device with the possibility of its drive [1].

The disadvantage of the known pumping unit is the low efficiency of the process of homogenization of the heterogeneous liquid mass of manure in the lagoon.

A known installation for homogenization and pumping of manure, containing associated with the drive mechanism, mounted on a shaft and enclosed in a casing of an inclined conveying auger associated with a grinding and mixing working body, communicated with the cavity of the casing of the conveying auger receiving chamber having a means of supplying manure into the transport line [ 2].

The disadvantage of the known device is that the installation has limited mobility when homogenizing and pumping liquid fertilizers from the lagoons of livestock complexes.

The closest to the utility model in terms of technical essence and the achieved result is a pontoon pump for homogenizing and pumping liquid organic fertilizers, containing a conveying auger connected to the drive mechanism, mounted on a shaft and enclosed in a casing, connected to a grinding and mixing working body, communicated with a cavity conveying auger housing; receiving chamber, wherein the grinding and mixing working body is made in the form of blades with longitudinal holes placed on the conveying auger shaft, the lower free end through a hinge fixed on the bottom plate and connected to the injection chamber located on the pontoon and fixed inside the latter blades [3].

The disadvantage of the known design is the lack of stability of the conveying auger of the pump relative to the vertical axis.

The objective of the proposed utility model is to create a new design of a pontoon pump with sufficient stability of the vertical position of the conveying auger during homogenization and pumping of liquid fertilizers from the lagoons of livestock complexes.

The problem is solved by the fact that the pontoon pump for homogenization and pumping of liquid organic fertilizers, containing a conveying auger connected to the drive mechanism, mounted on a shaft and enclosed in a casing, connected to a grinding and mixing working body, communicated with the cavity of the casing of the conveying auger a receiving chamber, moreover, the grinding and mixing working body is made in the form of blades with longitudinal holes placed on the conveying auger shaft, the lower free end is fixed on the bottom plate through the hinge and connected to the injection chamber located on the pontoon, and fixed inside the last blades. At the same time, a bushing of vertical stability is rigidly fixed on the pontoon coaxially to the conveying auger, and the casing of the conveying auger is installed with a guaranteed gap relative to the inner surface of the bushing.

Thanks to the vertical stability bushing of the pump, the efficiency of homogenization and pumping of liquid organic fertilizers from the lagoons of livestock complexes is increased.

The design is applicable for homogenization and pumping of liquid organic fertilizers from the lagoons of livestock complexes, which determines its versatility and simplicity.

A comparative analysis of the inventive pontoon pump for homogenization and pumping of liquid organic fertilizers and the prototype shows that the inventive pontoon pump differs from the known one in that a vertical stability bushing is rigidly fixed on the pontoon coaxially to the conveying auger, and the casing of the conveying auger is installed with a guaranteed clearance relative to the inner surface bushings.

The proposed utility model is illustrated by a drawing, which shows a sectional view of the proposed pontoon pump (Fig. 1), section A-A of the injection chamber (Fig. 2), the initial position of the pump on the pontoon (Fig. 3) and the final position of the pump on the pontoon (figure 4).

The pontoon pump for homogenization and pumping of liquid organic fertilizers contains a pontoon 1 with an injection chamber 2 placed on it with a branch pipe 3, a drive mechanism 4 connected to a shaft 5 fixed in bearings 6 and 7, the lower free end of which, through a hinge 8, is fixed to the bottom plate 9. In addition, on the shaft 5 there are: grinding and mixing working body 10, conveying auger 11, placed in the casing 12, and blades 13. The lower part of the casing 12 is connected to the receiving chamber 14, and the upper part of the casing 12 is loosely mounted on the sleeve 15 vertical stability.

The pontoon pump works as follows. The working part of the pump is mounted on pontoon 1 and plunges into the lagoon of the livestock complex. Through the bottom plate 9, the pontoon pump is fixed along the depth of the lagoon. The liquid organic fertilizer located in the lagoon is first homogenized by the grinding and mixing working body 10, mounted on the shaft 5, then the average mass of liquid organic fertilizers is sucked through the receiving chamber 14 into the area of the conveying auger 11 and moves through the cavity bounded by the casing 12 into the injection chamber 2, where it is captured by the rotating blades 13 and is discharged under pressure from the pontoon pump through the nozzle 3. The vertical position of the conveying auger 11 in the casing 12 is provided by the sleeve 15 of vertical stability, which explains the drawing from the initial position, when the depth of the liquid in the lagoon H (Fig.3) and the final position, when the depth of the liquid in the lagoon is minimal h, but the sleeve 15 allows you to maintain the vertical position of the casing 12 of the conveying auger 11, at the height of the pump above the pontoon α, thereby ensuring stable operation of the entire pontoon pump (Fig.4).

The efficiency of homogenization and pumping of liquid organic fertilizers in the lagoon of the livestock complex during operation distinguishes the proposed pontoon pump from the prototype.
