Abstract
The utility model provides a negative-pressure degassing system. The negative-pressure degassing system comprises a negative pressure barrel; a negative pressure pipe and a selective gas-permeable membrane are mounted in the negative -pressure barrel; a buffer barrel is connected to the bottom of the negative pressure barrel by use of a first electromagnetic valve; a drain outlet is connected to the bottom of the buffer barrel by use of a second electromagnetic valve; a liquid level sensor is further arranged on the buffer barrel; the liquid level sensor is connected with the two electromagnetic valves by use of a control circuit, respectively. The selective gas-permeable membrane is a PVC (Poly Vinyl Chloride) cluster microtube selective gas-permeable membrane and is U-shaped or S-shaped in the negative pressure barrel. The negative-pressure degassing system is additionally provided with the buffer barrel, so that leaked water is prevented from being sucked in by a negative pressure pump to cause damage. An electric control system is added to automatically detect the water volume in the buffer barrel, so that water in the buffer barrel can be drained without affecting the work of instruments. The PVC cluster microtube selective gas-permeable membrane is used for enhancing the water absorbing capacity, and the removal rate of moisture is increased by increasing the distance of travel of water in microtubes.
Description
Technical field
The utility model relates to medical biochemical analysis system field, specifically a kind of negative pressure degasification system.
Background technology
Mostly what the negative pressure degasification system that at present, Biochemical Analyzer uses adopted is monotubular multitube fiber ventilated membrane system.The defect of this system is, ventilated membrane is long-time to be used and have water and ooze out, and can be inhaled into negative pressure pump and cause negative pressure pump to damage in the time that water is accumulated to a certain degree.And gas can not be filtered completely in water, when instrument detects, application of sample precision is influenced.
Utility model content
The utility model, in order to solve the defect of existing monotubular multitube fiber ventilated membrane system, provides a kind of negative pressure degasification system, and the water that ventilated membrane oozes out can be discharged, and prevent from being inhaled into negative pressure pump and cause negative pressure pump to damage, and good filtration effect, precision is high.
The utility model comprises negative pressure bucket, and negative tube and selectivity ventilated membrane are housed in negative pressure bucket, and negative pressure bucket below is connected with buffer barrel by the first solenoid valve, and buffer barrel below is connected with freeing port by the second solenoid valve.Add buffer barrel in order to avoid the water of seepage is sucked and causes damage by negative pressure pump.
Further improve, described buffer barrel is provided with liquid level sensor, and liquid level sensor is connected with two solenoid valves respectively by control circuit.Add electric-control system and automatically detect the water yield in buffer barrel, to get rid of the water in buffer barrel in the situation that not affecting instrument work.
Further improve, described selectivity ventilated membrane is PVC boundling microtubule selectivity ventilated membrane, and selectivity ventilated membrane forms U-shaped or S type in negative pressure bucket.Use PVC boundling microtubule selectivity ventilated membrane to strengthen water-intake capacity, then by increasing the stroke of water at microtubule, improve the clearance of aqueous vapor.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model structure as shown in Figure 1, comprises negative pressure bucket 1, and negative tube 2 and selectivity ventilated membrane 3 are housed in negative pressure bucket 1, and negative pressure bucket 1 below is connected with buffer barrel 4 by the first solenoid valve 5, and buffer barrel 4 belows are connected with freeing port by the second solenoid valve 6.Add buffer barrel in order to avoid the water of seepage is sucked and causes damage by negative pressure pump.
Described buffer barrel 4 is provided with liquid level sensor 7, and liquid level sensor 7 is connected with two solenoid valves respectively by control circuit 8.Add electric-control system and automatically detect the water yield in buffer barrel, to get rid of the water in buffer barrel in the situation that not affecting instrument work.
Described selectivity ventilated membrane 3 is PVC boundling microtubule selectivity ventilated membrane, and selectivity ventilated membrane 3 forms U-shaped or S type in negative pressure bucket 1.Use PVC boundling microtubule selectivity ventilated membrane to strengthen water-intake capacity, then by increasing the stroke of water at microtubule, improve the clearance of aqueous vapor.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
