Description
Technical field
The present invention relates to oilfield, especially a kind of aspirator for tank cleaning.
Background technology
On oil field, sewage precipitation tank needs cleaning after a long time use, and current sewage precipitation tank mainly relies on manual cleaning.Manual cleaning surrounding need excavate water collecting sump below storage tank shell clean-out hatch, is used for receiving clean-out hatch and opens in rear tank and retain sewage, and uses simple pump that sewage in water collecting sump is transferred to roping in tank car to go out.There is a lot of drawback in this kind of cleaning method, as there is serious potential safety hazard, cleaning labour intensity is large, long construction period, crude oil recovery rate are low, and the problems such as contaminated environment, have not met the requirement of tank cleaning era development.
Summary of the invention
In order to overcome contaminated environment when existing sewage precipitation tank cleans, clean the deficiency that labour intensity is large, crude oil recovery rate is low, the invention provides a kind of aspirator for tank cleaning, this aspirator being used for tank cleaning ensures that in cleaning process liquid is not excessive, safety and environmental protection, cleaning efficiency is high, reduces labour intensity.
Technical scheme of the present invention is: a kind of aspirator for tank cleaning, comprise water storage tank for sewage water, bottom described water storage tank for sewage water, sidewall has inlet, inlet place is provided with feed liquor flange, water storage tank for sewage water inner bottom surface is fixed with U-shaped steam(-)coil, water storage tank for sewage water sidewall is fixed with liquid level gauge control panel, and liquid level gauge control panel is connected with the floating ball lever meter being placed in water storage tank for sewage water inside; Described water storage tank for sewage water top is fixed with vertical slag slurry pump, and the pump orifice of vertical slag slurry pump is connected with outlet pipe.
The present invention has following beneficial effect: owing to taking such scheme, water storage tank for sewage water passes through feed liquor Flange joint at the cleanout place of sewage precipitation tank, sewage in sewage precipitation tank can flow into water storage tank for sewage water, and water dirt is discharged by outlet pipe by vertical slag slurry pump.This aspirator can ensure airtight in sewage transfer process, safety, liquid are not excessive, avoid contaminated environment; Meanwhile, can be heated thickness sewage by the heat(ing) coil in storage tank, strengthen its mobility, improve the efficiency of tank clearly; Vertical slag slurry pump controls start and stop by frequency conversion system, can open and close automatically, realize unmanned, automatically control, save manpower according to the height of liquid level in storage tank, reduces labour intensity.

1-low water line in figure, 2-high-water line, 3-U type steam(-)coil, 4-disc type floating ball lever meter control panel, 5-floating ball lever meter, 6-electrical control cubicles, 7-vertical slag slurry pump, 8-motor, 9-ball-and-seat, 10-water storage tank for sewage water, 11-feed liquor flange, 12-outlet pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of aspirator for tank cleaning, comprises water storage tank for sewage water 10, bottom described water storage tank for sewage water 10, sidewall has inlet, inlet place is provided with feed liquor flange 11, and when cleaning storage tank, feed liquor flange 11 is connected with the clean-out hatch fluid flange of sewage precipitation tank.Water storage tank for sewage water 10 inner bottom surface is fixed with U-shaped steam(-)coil 3, the tank wall of sewage storage tank is provided with the connector of U-shaped steam(-)coil 3, heat(ing) coil can be connected with the steam pipe line of steam boiler, when in storage tank during liquid thickness, can heat liquid.Water storage tank for sewage water 10 sidewall is fixed with liquid level gauge control panel 4, and liquid level gauge control panel 4 is connected with the floating ball lever meter 5 being placed in water storage tank for sewage water 10 inside.Described water storage tank for sewage water 10 top is fixed with vertical slag slurry pump 7, and vertical slag slurry pump 7 is controlled by motor 8, and the pump orifice of vertical slag slurry pump 7 is connected with outlet pipe 12, and outlet pipe 12 is provided with check valve 9; Meanwhile, outlet pipe 12 end can also be provided with filter, filters liquid.Water storage tank for sewage water 10 outside is also fixed with electrical control cubicles 6, and motor 8, liquid level control plate 4 are all connected with electrical control cubicles 6.Can be set the height of high-water line 2 and low water line 1 by liquid level gauge control panel 4, thus control start-stop time of Pulp pump, when making liquid level reach high-water line 2, vertical slag slurry pump 7 is opened automatically, automatically closes when low water line 1.
This aspirator is placed within the scope of sewage precipitation tank tank body clean-out hatch 1.5m, and the feed liquor flange 11 on water storage tank for sewage water 10 is connected with sewage precipitation tank tank body by composite soft tube, opens flange, and in tank, namely sewage flow automatically in inflow water storage tank for sewage water 10.When in water storage tank for sewage water 10, liquid level reaches high-water line 2; vertical slag slurry pump 7 is opened; outwards liquid is transferred by outlet pipe 12; vertical slag slurry pump 7 is equipped with frequency conversion start stop system simultaneously; automatically the size of transfer flow can be adjusted according to fluid flow; when liquid level is lower than low water line 1, vertical slag slurry pump 7 autostop.
This device has the following advantages: 1. structure is simple, and volume is little, easy for installation, meets mechanical tank cleaning field demand; 2. this device collection transfer, be heated to be one, ensure airtight in transfer process, safety, liquid are not excessive, meet environmental requirement; 3. when there being thick liquid, by the heat(ing) coil of inside, liquid is heated, make it have certain mobility, even if external environment condition is severe, temperature is lower, do not affect the heating of liquid when fluid transfer temperature drop is large, without the need to additional heater before and after water tank again, improve the efficiency of mechanical tank cleaning yet yet; 4. by can realize the effect to media filtration in tank at the external filter of liquid outlet end.When liquid contain impurity more time, in order to filter inner impurity, add filtering function, liquid is by after screen pack, and contaminant filter affect pump transmission falls, and greatly reduces the loss of pump, while can improve the quality of liquid; 5. in Pulp pump distribution board, the automatic control PLC system of frequency conversion is installed, vertical slag slurry pump can control the flow of Pulp pump transfer liquid automatically according to pot liquid situation of flowing automatically, when liquid inlet volume is larger, the flow of pump also increases immediately, when the less flow to pump when stopping of liquid inlet volume also corresponding reduction is until stop; 6. controlled by automation PLC, achieve left unguarded, even if there is fault, system also can stop automatically, protects equipment.
