Description

Intelligent air lifting traveling crane type sand suction machine device

Technical Field

The utility model relates to the technical field of liquid pool bottom sewage lifting, in particular to an intelligent air-lifting traveling type sand suction machine device which is suitable for lifting out sewage at the pool bottom in an advection sand basin or an aeration sand basin of a sewage treatment plant.

Background

The travelling sand suction machine is a sand lifting mechanical device mainly used for aeration grit chambers of sewage treatment plants and water plants, most of the travelling sand suction machines are matched with sand suction pumps to be lifted into a sand discharge tank through sand discharge pipes, the using effect is not ideal, the travelling sand suction machine is mainly characterized in that precipitates in the grit chambers are complex, sand is not only sand, large-volume foreign matters and floccule dirt often exist, the sand suction pumps can be blocked frequently by the aid of the sand suction machine, the sand suction pumps are required to be lifted up to be cleaned frequently, and normal operation of equipment is influenced. There is therefore a need for a bladeless lifting device.

Although a travelling crane is provided with a fixed air lifting device, sand slag dirt can be lifted up by air lifting, the travelling crane is sometimes blocked; sometimes, the sand slag is deposited for a long time, the sand has high specific gravity and low water content, no fluidity is caused, a pipe orifice is blocked, the air lifting device cannot be used, the air lifting device can only be manually disassembled to clean and operate, and time and labor are wasted. Therefore, an automatic cleaning function is required.

No matter use sand suction pump or ordinary air lift pump, can't measure below the liquid whether have sediment and the filth that need promote, only can open hoisting device in succession or regularly, not only wasted a large amount of electric energy like this, also caused the waste of a large amount of water resources, not conform to the direction that the carbon of national advocated discharges, carbon neutralizes. Therefore, an intelligent gas stripping pump which needs energy conservation and emission reduction is arranged on the travelling crane.

The aeration grit chamber is the most common sand removing facility in urban sewage treatment plants in China, sand suction equipment is generally arranged on a bridge type truss car, and the biggest problem is that sand suction is not thorough. The reason for this is that sand is difficult to settle at the water inlet end and is deposited in a large amount at the water outlet end, the sand suction device of the aeration grit chamber is fixed and moves back and forth at the water inlet end and the water outlet end to suck sand, too much sand residue can cause damage to the sand suction device, and too little sand particle cannot suck sewage under the sand suction effect. Therefore, in actual operation, more sand grains can accumulate at the water outlet end of the aeration grit chamber, especially sand slag is increased instantaneously when rain and snow fall, the sand suction equipment is buried, the sand suction equipment cannot be stopped, and finally, the tank can only be emptied and then manually cleaned. Therefore, during operation, the sand suction equipment is required to continuously adjust the sand suction height and the machine shutdown time according to the sand slag accumulation degree of the sand collection tank, so that the required sand suction effect is achieved while the equipment is protected. The efficiency is improved, the energy is saved, the emission is reduced, and the carbon emission is reduced.

Therefore, need improve prior art, utility model a intelligence air stripping driving formula sand sucker solves the problem that exists more than.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: the defects of an existing mobile travelling sand sucker are overcome, the intelligent air travelling sand sucker has the advantages of being reasonable in structural design, safe, convenient to operate and use, low in maintenance cost, high in automation intelligence degree and the like, dirt in a liquid pool can be automatically lifted, and the intelligent air travelling sand sucker can be normally used in the severe environment.

In order to solve the problems in the background art and achieve the purpose, the utility model adopts the following technical scheme:

firstly, in the structure of an original travelling crane, an intelligent air stripping pump is used for replacing an original slag pump or a fixed stripping device, so that the problems that the travelling crane sand sucker cannot normally operate due to the fact that the stripping device is blocked or a pipeline is bent due to more sand slag, and the liquid in a liquid pool needs to be emptied to clean and maintain the stripping device when the travelling crane sand sucker is serious are solved; the measuring device senses the thickness of sand slag dirt through touch measurement, and the height of the dirt suction device is lifted to suck dirt according to the quantity of the sand slag dirt, so that the problems of dirt suction and energy saving are solved; and when the extreme sand slag is rich in dirt and the air lift pump opening is buried, the dirt suction opening can normally suck dirt on the sand slag through lifting the air lift pump.

The diameter and the double-hole structure of the gas stripping liquid pipe are increased, and the gas stripping pump and the back flushing are matched, so that the problem of blockage of the gas stripping pump is solved.

The intelligent air-lift traveling type sand sucker comprises 1 a liftable intelligent air lift pump; 2. fixing a movable air stripping pump bracket; 3. An intelligent device of a gas stripping pump; 4. a fan, 5, an automatic control system; 6. moving the travelling crane; 7. the slag scraper can be lifted.
