Description

Slurry pump for sewage treatment

Technical Field

The utility model belongs to the technical field of the sediment stuff pump and specifically relates to a sediment stuff pump for sewage treatment is related to.

Background

Along with the development of times and science and technology, the living standard of people is increasingly improved, the requirement of human beings on the living environment is increasingly high, the pollution of water resources becomes one of the most concerned problems of society, all the time, the field production units such as various stone factories, ore dressing plants and the like always face the problem of purification and recycling of production sewage, the requirement on the used slurry pump is higher, the pipeline and a pipeline valve are blocked frequently due to larger crushed stones and slag contained in water in the ore industry, the operation of the slurry pump is stopped, and the sewage in the pipeline begins to flow back due to pressure loss, so that the slurry pump needs to be detached to clean the slag, time and labor are wasted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sediment stuff pump for sewage treatment, it has solved the great sediment that causes of sewage in the sewage stuff pump shut down, sewage backward flow scheduling problem.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the utility model provides a sediment stuff pump for sewage treatment, includes pneumatic valve, filter equipment, sediment stuff pump body, valve and play thick liquid pipe, the pneumatic valve right side sets up filter equipment, filter equipment includes baffle and filter screen, the baffle is upright to be placed, the filter screen is located the baffle lower extreme and perpendicular with the baffle, the filter equipment right side is equipped with the sediment stuff pump body, sediment stuff pump body right side is connected go out the thick liquid pipe, be equipped with the water conservancy diversion hole under going out the thick liquid pipe, water conservancy diversion hole below corresponds position sealing connection the valve.

Preferably, the baffle is made of artificial fiber cloth.

As the utility model discloses a preferred, the filter screen comprises the stainless steel, is difficult for being corroded the damage.

As the optimization of the utility model, the meshes of the filter screen are square and 40 multiplied by 40mm in size.

As the utility model discloses a preferred, the play thick liquid pipe is provided with the check valve, prevents the sewage backward flow.

As the utility model discloses a preferred, sewage import pipe diameter is 254mm, and sewage outlet pipe diameter is 203 mm.

As the utility model discloses a preferred, the filter equipment lower part is equipped with the second valve, through the second valve, can will be because of unable through the filter screen, the great slag clearance under the sediment goes out.

The utility model has the advantages of it is following:

through having set up filter equipment, can keep apart some and probably cause the dead stone of sediment stuff pump impeller card or slay etc. before sewage gets into the sediment stuff pump body, and the device simple structure, anticorrosive, can effectual protection impeller, through having set up water conservancy diversion hole and valve, can be after sediment stuff pump stop work, open the sewage discharge that the valve stores up in with the sediment stuff pump, labour saving and time saving, and set up the check valve, effectively prevent the sewage backward flow.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is an overall schematic view of the present invention;

in the figure: 1. the slurry pump comprises a pneumatic valve, 2, a filtering device, 3, a slurry pump body, 4, a valve, 5, a slurry outlet pipe, 20, a baffle, 21, a filter screen, 22, a second valve, 40 and a flow guide hole.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1, a slurry pump for sewage treatment, including pneumatic valve 1, filter equipment 2, slurry pump body 3, valve 4 and play thick liquid pipe 5, pneumatic valve 1 right side sets up filter equipment 2, filter equipment 2 includes baffle 20 and filter screen 21, baffle 20 is upright to be placed, filter screen 21 is located baffle 20 lower extreme and perpendicular with baffle 20, 2 right sides of filter equipment are equipped with

slurry pump body

3, 3 right sides of slurry pump body are connected play thick liquid pipe 5, be equipped with water conservancy diversion hole 40 under play thick liquid pipe 5, water conservancy diversion hole 40 below corresponds position sealing connection valve 4.

Further, the baffle 20 is made of rayon cloth.

Further, the filter screen 21 is made of stainless steel and is not easily corroded and damaged.

Furthermore, the meshes of the filter screen 21 are square, and the size of the meshes is 40 multiplied by 40 mm.

Further, the slurry outlet pipe 5 is provided with a one-way valve to prevent sewage from flowing back.
