Abstract
The present invention relates to a vacuum collecting tank which is composed of a cavity tank body and an auxiliary tank communicated with the cavity tank body, wherein the auxiliary tank is divided into an upper tank and a lower tank by a partition plate; a pressure spring positioned in the lower tank supports a movable gate and seals a through hole in the partition plate to form an isolating valve; the tank wall of the upper tank is provided with a sewage pipe inlet and a vacuum air source interface hole, and the side wall of the lower tank is provided with a valve interface hole; the tank body is provided with an outlet channel. The present invention has the advantage of simple structure. A vacuum collecting system of the present invention, which is adopted, has the advantages of convenient use and easy maintenance, and thereby, the continuous operation of the vacuum collecting system can be ensured. Simultaneously, the equipment investment for a pollution discharging valve and a vacuum valve is saved more than 70 %.
Description
The present invention is a kind of container that loads liquid, solid mixt, is used in particular for collection and discharging that the water ballast block is in vacuum state.
The vacuum dirt of being recognized is at present collected exhaust system, uses the single-stage vacuum tank to collect sewage and ight soil as vacuum closet etc. always, and dirt fills with the back and sends signal by sensor and make dredge pump work in the collecting tank, a dirt in getting rid of jar.The a technical data in U.S. AIRVAC company in July, 1997 shows this situation.Owing to must guarantee that the user still can use during blowdown, promptly sewage continues to suck vacuum tank, so will keep 0.4～0.5 atmospheric partial vacuum state in the jar.Dredge pump work must overcome negative pressure of vacuum, otherwise sewage can not get rid of, and common dredge pump is difficult to competent this task, must use the powerful dredge pump of high suction depth, for preventing that jar interior vacuum from revealing from dredge pump, between vacuum tank and pump, also solenoid vacuum valve should be set, open and close synchronously with dredge pump.The powerful dredge pump price of bigbore solenoid vacuum valve and high suction depth is more than 4～5 times of common one way valve and dredge pump, costs an arm and a leg, and in addition, solenoid vacuum valve is easy break-down in use, and the maintenance of the powerful dredge pump of high suction depth is more complicated also.
The object of the present invention is to provide a kind of vacuum colletor, this collecting tank is with the auxiliary tank of a band isolating valve, thereby the effect that can use cheap vacuum valve and dredge pump to reach smooth blowdown reduces system cost, makes things convenient for working service.
Vacuum colletor of the present invention, by having intake channel and exit passageway on the cavity tank body, it is characterized in that described tank body intake channel connects with auxiliary tank, auxiliary tank is divided into jar and following jar by dividing plate, have through hole on the dividing plate, the stage clip support valve that is positioned at following jar is sealed through hole, constitutes isolating valve, last jar of tank skin has soil pipe import and vacuum source interface holes, and following pot sidewall has the valve interface hole.
Described vacuum colletor, described tank body can connect by flange with following jar of auxiliary tank at the intake channel place, and the upward jar of auxiliary tank also can connect by flange with following jar.
Described vacuum colletor, described stage clip and valve can be positioned on the gripper shoe across described tank body intake channel.
Described vacuum colletor, described stage clip and valve also can be positioned on the support that is suspended on described dividing plate.
The present invention is simple in structure, can guarantee the continuous operation of vacuum collecting system, and dirt is collected discharging and neglected neither.The equipment investment of dredge pump and vacuum valve is simultaneously saved more than 70%, adopt vacuum collecting of the present invention system easy to use, safeguard easily.
Fig. 1 is for using vacuum collecting system schematic of the present invention.
Fig. 2 is in the schematic diagram of isolating station for auxiliary tank of the present invention.
Fig. 3 is in the schematic diagram of opening station for auxiliary tank of the present invention.
In Fig. 1-Fig. 3, be equipped with liquid level sensor 7 in the tank body 1, the tank body intake channel connects by flange with auxiliary tank, auxiliary tank is divided into jars 3 and following jar 6 by dividing plate 11, being positioned at following jar stage clip 13 supports valve 12 and seals through hole 10 on the dividing plate, constitute isolating valve 5, last jar 3 tank skin has soil pipe import 4 and vacuum source interface holes 14, and following jar of 6 sidewalls have valve interface hole 15.
When this vacuum collecting tank is used for the vacuum collecting system, be connected as Fig. 1 mode with vacuum pump 16, two-position four-way valve 17, vacuum meter 2, one way valve 8, dredge pump 9.When two-position four-way valve 17 was connected vacuum pumps with the valve interface hole 15 of following jar 6 of auxiliary tank, upper and lower jar all was in the partial vacuum state, and sewage sucks from soil pipe import 4 and goes up jars 3 in the pipe network, under the sewage gravity pressure, pushes valve open and flows into following jar 6.When sewage fills with down jar, liquid level sensor 7 start-up control devices, two-position four-way valve 17 commutations, following jar 6 by valve interface hole 15, two-position four-way valve 17 communicates with atmosphere, vacuum drops near atmospheric pressure, start dredge pump 9 blowdowns simultaneously, the draft of dredge pump is enough to overcome the valve gravity of one way valve 8, sewage is discharged in tank body 1 smoothly, owing to still keep the partial vacuum negative pressure state in last jar 3, valve 12 in the isolating valve 5 is last, pressure reduction and stage clip 13 effects further compress through hole 10 down in following jar, guarantee that user's sewage continues and can suct into jar in the following jar of blowdown process.Last jars 3 should have enough volumes, are enough to hold following jar user during with the tank body blowdown and discharge the sewage that enters.
Sewage drains in the tank body 1, and liquid level sensor 7 sends signal, and control device quits work dredge pump 9, one way valve 8 starts the sealing blowdown channel immediately, two-position four-way valve 17 recovers original state, and auxiliary tank is connected with vacuum pump again for following jar 6, restarts the next round circulation.
