Abstract

The utility model relates to a double-helix casing type mining submersible sewage coal slurry pump and belongs to the field of pumps for coal slurry treatment. The pump comprises a pump casing, wherein helical drainage channels are processed on the pump casing. The pump has the technical point that the two helical drainage channels are symmetrically processed on two sides of the bump casing. Through an improvement on the prior art, the two helical drainage channels are symmetrically processed on two sides of the bump casing, so that a backward radial force generated during the running of the pump is balanced, which guarantees the normal and stable running of the pump, reduces the production cost of an enterprise and prolongs the service life of the pump.

Description

The double helix shell-type is mining latent dirty coal slurrypump

Technical field

The utility model belongs to and is used for the pump class field that coal slime is handled, particularly a kind of double helix shell-type is mining latent dirty coal slurrypump.

Background technique

At present, industries such as domestic colliery, metallurgy, electric power can produce with a large amount of coal slimes in process of production; If the direct emission treatment of this part coal slime not only causes environmental pollution, and can cause very big economic loss; Therefore each manufacturing enterprise is many carries out making full use of after the processing to these coal slimes; Or do other purposes, this just need be drawn into predetermined location with these coal slimes that pump will produce and handle, but has had impurity such as many granular, floccule in these coal slimes; Cause common pump normally to use, this just makes needs some specialized apparatus on coal slime is handled.For this reason, associated pump class professional production producer has designed special-purpose coal slurrypump, the appearance of these coal slurrypumps to the high characteristics of coal slime impurity content; Solved conventional pump to a great extent and be used for the problem of coal slime suction difficulty of transportation, but in the actual production process of manufacturing enterprise, found that these coal slurrypumps are processed with spiral draining runner because of a side at pump case; Make pump when proper functioning, produce bigger reverse radial force; This part reverse radial force receives force unbalance when causing the pump running, causes the not steady of pump operation, has strengthened the friction of mechanical seal; Shortened the whole service life of pump greatly; Directly strengthened the cost of production of enterprise, how can solve this technological deficiency, become and demand the problem studied in the industry urgently.

The model utility content

The purpose of the utility model is to overcome the deficiency that exists in the above-mentioned existing technology, provides a kind of simple in structure, can ensure normal, the stable operation of pump, cuts down the consumption of energy, and improves the pump mining latent dirty coal slurrypump of double helix shell-type in working life.

The utility model solves the technological scheme that its technical problem adopted:

Be the mining latent dirty coal slurrypump of a kind of double helix shell-type, comprise pump case, be processed with helical draining runner on the pump case, the present technique main points are that the pump case bilateral symmetry is processed with two helical draining runners.

After the utility model institute carries out above-mentioned improvement to existing technology; Owing to processed two helical draining runners in the pump case bilateral symmetry; The reverse radial force of in the time of can making pump operation all obtains balance; Therefore ensure normal, the stable operation of pump, reduced the cost of production of enterprise again, prolonged the working life of pump.

Description of drawings

Fig. 1: the mounting structure schematic representation of the utility model.

Among the figure: 1, pump case; 2, the draining runner one; 3, the draining runner two.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be further described:

As shown in Figure 1, this double helix shell-type is mining latent dirty coal slurrypump comprises pump case 1, is processed with helical draining runner on the pump case 1, and the present technique main points are that pump case 1 bilateral symmetry is processed with two helical draining runners one and helical draining runner two.

After the utility model institute carries out above-mentioned improvement to existing technology; Owing to processed two helical draining runners in the pump case bilateral symmetry; The reverse radial force of in the time of can making pump operation all obtains balance; Therefore ensure normal, the stable operation of pump, reduced the cost of production of enterprise again, prolonged the working life of pump.

Claims (1)

1. the mining latent dirty coal slurrypump of double helix shell-type comprises pump case, is processed with helical draining runner on the pump case, it is characterized in that the pump case bilateral symmetry is processed with two helical draining runners.
