Abstract

(57) [Summary] (Corrected) [Purpose] By combining a pump with a large treatment air volume but a low vacuum achievement and a pump with a small treatment air quantity but a high vacuum achievement, It does not require a complicated structure for a high-priced device, and it can be easily made compact and lightweight by using a check valve and can be manufactured at low cost. [Structure] A check valve 3 is attached to a pressure vessel and suction is performed by a pump 1 having a large processing air volume. In addition, a separate connection port 6 is provided so that the suction port 7
The gas sucked from is rapidly discharged by the pump 4 and reduced in volume. If the suction of the pump of No. 1 is performed, the pressure becomes equal to that in the container, and the check valve closes due to the weight of the valve 10, and the operation of the pump of No. 1 stops. However, the 2nd pump continues to work, and the reduced gas can be discharged little by little and sucked up to a high degree of vacuum.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 When a container that requires intake air has a large capacity and a high degree of vacuum, it can be used as a device that is faster in time, simpler in device, smaller in size and lighter in weight, cheaper in maintenance cost, and easier in operation.

[0002]

[Prior Art]

 As a conventional degassing pump, a model with a large treatment air volume but a low vacuum achievement, or a model with a small treatment air quantity but a high vacuum achievement and a large treatment air volume and a high vacuum degree is the latter model. I had no choice but to upsize. In addition, when the former and the latter are connected and used, complicated electrical operations such as solenoid valves and piping such as differential valves were required.

[0003]

[Problems to be solved by the device]

 When the size of the pump is increased, the weight is increased, the cost is high, and the maintenance cost is also high. Further, even when two different pumps are connected, the operation is complicated and causes a failure, and the cost is high.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, a check valve (3) is attached to the pressure vessel (5) as shown in Fig. 1 as a means to create a pump with a large processing air volume and a high vacuum level. And the connection port (6) of the pump (2) having a small processing air volume but a high vacuum reaching pressure is attached. Connect the inlet (7) to the container (9) that needs degassing, connect (1) and (2) to (4) and (6), and operate (1) and (2) simultaneously During the operation (9), the gas (8) is first discharged in a short time by the action of (1). If degassing is performed up to the vacuum reaching point in (1), the pressure in the part (4) and the pressure in (8) become the same pressure, and the check valve (10) is automatically closed by weight (2). Only the pump function of continues to operate. Since the remaining amount of (8) is small due to the function of (1), it is possible to process with a small processing air volume of the pump of (2), and it is possible to reach a high degree of vacuum. Taking advantage of this point, by combining two or more pumps with special characteristics, a degassing mixing device that uses a check valve for the purpose of producing a large effect.

[0005]

[Action]

 The usage of this invention is that, when used as a device with a large processing air volume and a high degree of vacuum, the processing air volume is determined by the capacity of (1) and the ultimate vacuum pressure can be set by the capacity of (2) according to the purpose. Since it can be selected, it can be used as a device as needed and can be made compact and lightweight. Further, as shown in FIG. 3, a hopper (11) is installed inside (5) and a drain port (12) and a drain cock (13) are installed so that it can be used as a mixing tank having a water separating function. I can.

[0006]

【Example】

 A vacuum pack for maintaining the freshness of foods, speeding up the vacuum in a large-capacity container, and a high-vacuum pack such as a weight loss pack by degassing are required. I can. In addition, by providing a water separation function, it is possible to maintain high vacuum and degas quickly even if the content volume contains water.

[0007]

[Effect of the device]

 By drawing out and combining only the advantages of two or more pumps with their respective advantages to create a high-level deaerator, the advantage is that the combination that matches the pump's ability can be freely selected, and it is small and lightweight. As a result, equipment costs are low, maintenance costs are low, operation is simple, and it is possible to reduce the degassing time.

Claims (1)

[Scope of utility model registration request] 1. When a deaeration pump (1) having a large treated air volume and a low vacuum reaching point and a deaeration pump (2) having a small treated air quantity and a high vacuum reaching point are combined, an intake port (2) is provided in a pressure vessel. By providing a connection port for (1) equipped with a check valve and a check valve, the gas in the container that needs to be inhaled can be supplied with a large air volume by the pump of (1) and the pump of (2). When the gas is processed and sucked, and the ultimate pressure of the pump of (1) becomes equal to the pressure of the container that requires suction, the check valve falls and the suction of the pump of (1) stops. By degassing a small amount of gas remaining in the pump of (2) up to a high pressure at the vacuum reaching point, a deaeration using a check valve that can create a pump with a large processing air volume and a high vacuum reaching point Mixing equipment.
