Drawings
Fig. 1 is a schematic structural diagram of a storage tank structure according to the present invention.
Part label name in the figure: 1-tank body, 2-suction valve, 3-filtering device, 4-exhaust valve, 5-cleaning pipe and 6-pumping pipe.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The storage tank structure shown in fig. 1 mainly comprises a tank body 1, an air suction valve 2, an exhaust valve 4, a cleaning pipe 5 and a pumping pipe 6, wherein the air suction valve 2 and the exhaust valve 4 are respectively and fixedly installed on the tank body 1, the cleaning pipe 5 and the pumping pipe 6 are respectively and fixedly connected with the tank body 1, and the cleaning pipe 5 and the pumping pipe 6 are respectively communicated with an inner cavity of the tank body 1. When the pressure of the inner cavity of the tank body 1 is lower than the external environment pressure of the tank body 1, the suction valve 2 is opened, and the exhaust valve 4 is closed. However, when the pressure in the inner cavity of the tank 1 is higher than the external ambient pressure of the tank 1, the exhaust valve 4 is opened and the intake valve 2 is closed.
In the process of material pumping operation through the material pumping pipe 6, the material liquid in the inner cavity of the tank body 1 is continuously pumped outwards through the pump, and the inner cavity of the tank body 1 can form a negative pressure state. When the pressure of the inner cavity of the tank body 1 is lower than the pressure of the external environment of the tank body 1, the suction valve 2 is opened, the exhaust valve 4 is closed, and air is continuously sucked through the suction valve 2, so that the pressure of the inner cavity of the tank body 1 can be maintained in a normal state, the tank body 1 is ensured not to be deformed and damaged, the inner cavity of the tank body 1 is effectively ensured not to be influenced by the external environment of the tank body, and the cleanliness of the inner cavity of the tank body 1 is further well ensured.
When cleaning the inner cavity of the tank body 1, hot water at 75-95 ℃ is generally injected into the inner cavity of the tank body 1 through the cleaning pipe 5, and the pressure of the inner cavity of the tank body 1 is increased by the hot steam in the inner cavity of the tank body 1. When the pressure of the inner cavity of the tank body 1 is higher than the pressure of the external environment of the tank body 1, the exhaust valve 4 is opened, and the suction valve 2 is closed, so that hot steam in the inner cavity of the tank body 1 can be normally discharged through the exhaust valve 4 in time, the pressure of the inner cavity of the tank body 1 is normal, the tank body 1 is ensured not to be deformed and damaged, meanwhile, the inner cavity of the tank body 1 can be effectively ensured not to be influenced by the external environment of the tank body, and the cleanliness of the inner cavity of the tank body 1 can be well ensured.
In order to further improve the cleanliness of the inner cavity of the tank body 1, a filtering device 3 can be arranged on the air suction valve 2, and the filtering device 3 can adopt a hundred-grade filtering net and also can adopt a positive pressure type hundred-grade filter. Through setting up filter equipment 3, can improve the cleanliness factor of the gas that gets into jar body 1 inner chamber from inspiratory valve 2 to be favorable to improving the cleanliness factor of jar body 1 inner chamber. Usually, the suction valve 2 and the exhaust valve 4 are respectively and fixedly installed on the top of the tank body 1, the cleaning pipe 5 is fixedly connected to the top of the tank body 1, the pumping pipe 6 is fixedly connected to the bottom of the tank body 1, and the pumping pipe 6 is arranged opposite to the suction valve 2. By adopting the structural design, on one hand, hot water can be conveniently and smoothly injected into the inner cavity of the tank body 1 through the cleaning pipe 5, and on the other hand, convection can be better formed in the inner cavity of the tank body 1, so that the cleanliness of the inner cavity of the tank body 1 is favorably improved, and the tank body 1 is ensured not to be deformed and damaged.
