Description
Technical Field
The utility model relates to a glass grinding device technical field specifically is a gas-liquid mixture looks desilting device.
Background
When the glass is ground, the sedimentation tank is used for collecting wastewater of a surface grinding workshop, and the main components of the wastewater of the surface grinding workshop are polishing powder, a small amount of polyurethane fragments and trace glass powder. The surface grinding wastewater has the characteristics of high viscosity and easy caking after being precipitated in the precipitation tank, and is difficult to clean. The traditional cleaning method is to regularly organize personnel to fall into a sedimentation tank for manual cleaning.
This practice has the following disadvantages:
firstly, the labor intensity of personnel is high, the personnel is generally required to wear protective articles, and the sludge is filled into the gunny bag by using shovels, shovels and the like at the bottom of the sedimentation tank, so that the labor intensity of the personnel is high due to the high viscosity of the sludge caking.
Secondly, the shortcoming of the operation environment is abominable, because of personnel need pass the protective clothing and go down the sedimentation tank bottom, personnel are difficult to exempt from to glue polishing powder in operation process, pollute staff's clothing, pollute staff's skin, and frequent operation leads to the skin disease easily. The sludge is fermented after long-term deposition, the bottom smell is unpleasant, and a gas mask needs to be worn during operation.
And thirdly, potential safety hazards exist. When in desilting operation, a person wears a protective clothing and puts down the protective clothing to the bottom of the sedimentation tank, and the sludge is fermented after being deposited for a long time, so that toxic components are contained in the gas, and the person is likely to suffocate after long-time operation. For example, the depth of the sludge exceeds the height of the human body, which can cause people to be trapped in the sludge and endanger the safety of operators.
And fourthly, the workshop operation environment is polluted, the polished sludge after manual dredging needs to be transported out of the polishing workshop by using a woven bag, and the polishing solution leaks in the transporting process to pollute the passing route of the transportation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a gas-liquid mixture looks desilting device, the device can clear up the silt in the polishing sedimentation tank automatically effectively, gives up artifical clearance mode, improves desilting efficiency.
The utility model provides a technical scheme that its technical problem adopted is:
a gas-liquid mixed phase desilting device comprises an annular pipe arranged at the lower part of the inner wall of a polishing and settling tank, wherein two sides of the annular pipe are respectively communicated with a vertical medium pipe, and the top end of the medium pipe is communicated with a water pipe and an air pipe; the water pipe and the air pipe are respectively provided with a flow regulating valve; the annular pipe is provided with a group of lower spray holes and a group of inclined spray holes along the circumference, the lower spray holes are positioned at the bottom of the annular pipe, and the inclined spray holes are positioned on the inner side of the annular pipe and inclined downwards; and a sewage pump is also arranged in the polishing sedimentation tank.
Further, the inclined spray holes are inclined downwards at an angle of 45 degrees.
The utility model has the advantages that the mixed gas-liquid mixed fluid in the medium pipe is sprayed out through the spray holes of the annular pipe, the lower spray holes enable the gas-liquid mixed fluid to vertically face downwards and enable the sludge to be impacted and loosened, the inclined spray holes enable the gas-liquid mixed fluid to incline downwards and enable the sludge to be flushed towards the sludge pump direction, and the sludge pump is convenient to draw the sludge out of the polishing sedimentation tank; the device overcomes the defect of manual dredging, automatically dredges, and has good cleaning effect and high efficiency.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a side view of the present invention, ignoring the sewage pump;
fig. 3 is an enlarged schematic view of the lower nozzle hole and the inclined nozzle hole of the present invention.
Detailed Description
As shown in fig. 1, the utility model provides a gas-liquid mixed phase dredging device, which comprises an annular pipe 2 arranged at the lower part of the inner wall of a polishing sedimentation tank 1, wherein both sides of the annular pipe 2 are respectively communicated with a vertical medium pipe 3, the top end of the medium pipe 3 is communicated with a water pipe 4 and an air pipe 5, and the medium pipe 3, the water pipe 4 and the air pipe 5 can be connected by a tee joint; a water flow regulating valve 6 is arranged on the water pipe 4, and an air flow regulating valve 7 is arranged on the air pipe 5; the annular pipe 2 is respectively provided with a group of lower spray holes 8 and a group of inclined spray holes 9 along the circumference, the lower spray holes 8 are positioned at the bottom of the annular pipe 2, and the inclined spray holes 9 are positioned at the inner side of the annular pipe 2 and inclined downwards; preferably, the inclined spray holes 9 are inclined downwards at an angle of 45 degrees. The polishing and settling tank 1 is also internally provided with a sewage pump 10, and the sewage pump 10 is preferably arranged at the center of the polishing and settling tank 1 and is lower than the annular pipe 2.
Water is introduced into the water pipe 4, compressed air is introduced into the air pipe 5, gas-liquid mixed fluid enters the medium pipe 3, and the mixing proportion of gas and liquid can be changed by adjusting the water flow regulating valve 6 and the gas flow regulating valve 7 so as to adapt to different dredging requirements. The liquid flow proportion is large when cleaning the upper layer, which is helpful to wash the bottom sludge loose. When the bottom layer is cleaned, the gas flow proportion is large, and the impact force of the mixed fluid is increased. The gas-liquid mixed fluid is sprayed out through the spray holes of the annular pipe, the lower spray hole 8 enables the gas-liquid mixed fluid to vertically face downwards to enable sludge to be impacted and loosened, the inclined spray hole 9 enables the gas-liquid mixed fluid to incline downwards to enable the sludge to be impacted towards the direction of the sludge pump, the functions of guiding flow and enlarging an impact plane are achieved, and the sludge is conveniently pumped out of the polishing and settling tank by the sludge pump; the device overcomes the defect of manual dredging, automatically dredges, and has good cleaning effect and high efficiency.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments according to the invention, and may be used in various other applications, including, but not limited to, industrial.
