Abstract
The utility model provides a mouth cavity vacuum continuously sucking dual-tank automatic switching liquid-gas separating control device, which is characterized in that the control device is formed by the longitudinal connection of an upper separating tank (1) and a lower separating tank (2); an upper end interface (8) of the upper separating tank (1) is connected with a vacuum pump; an interface (7) is connected with a user terminal; a lower end interface (9) of the upper separating tank (1) is connected with the lower separating tank (2) through a first unidirectional valve (3); a lower end interface of the lower separating tank (2) is connected with a second unidirectional valve (4), so that sewage is discharged; an upper scavenging port (10) of the upper separating tank (1) is connected with a lower scavenging port (11) of the lower separating tank (2) through a reversing valve (6) so as to control equipressure and disconnection between two tanks; and a liquid level sensor (5) is installed at the middle part of the lower separating tank (2) so as to control sewage discharge. Through the disconnection and connection of the upper separating tank (1) and the lower separating tank (2), the sewage discharge is controlled, and the halting problem of single-tank self-weight water draining is prevented; through self-weight water draining, the problem that a single-tank water pump in water drainage is halted because of water pump stoppage is prevented through self-weight water drainage. The mouth cavity vacuum continuously sucking dual-tank automatic switching liquid-gas separating control device provided by the utility model has the beneficial effect that the defect that the existing single-tank separating device on the market needs to be halted or additionally provided with a water suction pump is overcome effectively.
Description
Technical field:
New technique of the present invention is a kind of device that the materials such as the liquid that attracts in the dental care process to come, gas are separated automatically.
Background technology:
At present, in the dental care process, the negative pressure of vacuum suction system adopts single tank separator usually.One-pot is equipped with two major defects:
1 deadweight draining, Loss of vacuum, suction stops; Liquid in tank reach a certain height, need to the deadweight mode will be wherein fluid removal the time, in case discharge outlet is opened, the inside and outside pressure differential of tank will disappear, Loss of vacuum at this moment, and suction system stops, dental care work might be forced to interrupt like this, and the wait draining is finished.
2 add the water plug failure risk increases, in order to keep vacuum in the tank, generally need add suction journey water pump water is taken away, it is large to inhale journey water pump volume, and cost is high, complex structure, and blood, disease, residue etc. are also often arranged in the aspirate, to water pump meeting injury, in a single day water pump goes wrong, whole suction system will be paralysed, and dental care work can not normally be carried out.
The utility model content:
In order to address the above problem, the utility model provides the two tank automatic switchover liquid of a kind of oral cavity vacuum continuous sucking, gas separation control device, and it is characterized in that: described control device is connected to form up and down by upper knockout drum (1) and lower knockout drum (2); The upper end interface (8) of upper knockout drum (1) is connected with vavuum pump, and interface (7) is connected with user side, and lower end interface (9) is connected by the first check valve (3) with lower knockout drum (2); The lower end interface of lower knockout drum (2) connects the second check valve (4), and sewage is discharged; The upper scavenge port (10) of upper knockout drum (1) is connected with the lower scavenge port (11) of lower knockout drum (2) by reversal valve (6), to control isobaric between two tanks and to disconnect; Liquid level sensor (5) is installed in lower knockout drum (2) middle part, is used for controlling the discharging of sewage.By the disconnection and closure of upper knockout drum (1) and lower knockout drum (2), control the discharging of sewage, avoided the halting problem of single tank deadweight draining.By deadweight draining, the problem of having avoided the draining of single tank water pump to shut down because of the water pump fault.The beneficial effect of this utility model is effectively to have overcome the deficiency that suction pump need to be shut down or add to existing single tank separator on the market.
Description of drawings:
Fig. 1 is the structure chart of the two tank automatic switchover liquid of oral cavity vacuum continuous sucking, gas separation control device.
The specific embodiment:
1 when the vacuum pump startup, and the mixture of liquid (12) and gas (13) enters upper knockout drum (1) through interface (7) to be separated:
A gas (13) is discharged outdoor through connecting upper end interface (8) the suction vavuum pump of vavuum pump through vavuum pump;
B liquid (12) flows into lower knockout drum (2) through after precipitating through the first check valve (3);
Upper scavenge port (10) and lower scavenge port (11) communicate under this state of c, and two tanks are with pressing, and the first check valve (3) is opened, the second check valve (4) closure;
2 when liquid level rises to liquid level sensor (5) position,
A liquid level sensor (5) outputs signal to controller, controller is changed reversal valve (6), scavenge port on this moment (10) and lower scavenge port (11) disconnect, extraneous air (14) enters lower knockout drum (2), cause two knockout drums to produce pressure reduction, the first check valve (3) closure, the second check valve (4) is opened, and the liquid that is deposited in lower knockout drum (2) bottom is discharged by deadweight.
As usual running of vavuum pump under this state of b, the liquid precipitation that suction is come in is in the tank body of upper knockout drum (1).
3 after the water discharge time of setting finishes, and controller is multiple to switch to laststate with reversal valve (6), continues to repeat a program.
