DETAILED DESCRIPTION

[0013] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0014] like Figure 1-2 The RTO lifting valve compressed air buffer tank shown comprises a tank body 1, and an air outlet pipe 2 and an air inlet pipe 3 are respectively connected on the outer walls of the top and bottom ends of the tank body 1. The compressed air driving the lifting valve enters the tank body 1 from the air inlet pipe 3, and is transported from the air outlet pipe 2 to the cylinder of the lifting valve for driving. It is characterized in that a filter dehumidification component is arranged in the middle of the inner cavity of the tank body 1, and a pressure difference sensor 4 is arranged on the outer side of the middle of the tank body 1. The pressure difference sensor 4 is connected to two sensing tubes 5. The other ends of the two sensing tubes 5 are fixed on the outer wall of the tank body 1. The two sensing tubes 5 are respectively connected to the inside of the tank body 1 located above the filter dehumidification component and the inside of the tank body 1 located below the filter dehumidification component;

[0015] On the basis of the above, the air intake pipe 3 is connected to the external air supply pipeline, and the air intake pipe 3 is connected to the cylinder of the lifting valve. When working, the compressed air that drives the lifting valve enters the interior of the tank body 1, is processed by the filtering and dehumidification component, and then enters the cylinder of the lifting valve through the air intake pipe 3, driving the lifting valve to work.

[0016] Furthermore, the size of the tank body 1 is proportional to the specification of the lift valve cylinder. Part of the gas can be stored in the tank body 1. When the external gas supply pipeline fails, the part of the gas stored in the tank body 1 can ensure that the lift valve can work normally once or twice.

[0017] An inspection door 6 is provided on the outer wall of the middle part of the tank body 1, a sealing valve 7 is installed in the inspection door 6, and a handle 8 for opening the sealing valve 7 is installed on the outer wall of the sealing valve 7;

[0018] On the basis of the above, after working for a long time, the filter dehumidification component may be partially blocked due to the large amount of dust and water vapor in the compressed air. The sealing valve 7 can be opened through the handle 8, and the filter dehumidification component inside the tank body 1 can be replaced and maintained through the inspection door 6.

[0019] A drain pipe 9 is connected to the bottom end of the tank body 1, and a stop valve 10 is installed on the drain pipe 9;

[0020] After working for a long time, some water will accumulate at the bottom of the inner cavity of the tank body 1, and the water can be discharged through the drain pipe 9 and the stop valve 10.

[0021] The filtering and dehumidifying components are arranged in a plurality of groups, and the plurality of groups of filtering and dehumidifying components are arranged in sequence inside the tank body 1;

[0022] The filter dehumidification assembly includes a slide rail 11 fixed on the two side walls of the inner cavity of the tank body 1, a filling plate 12 that slides back and forth is inserted in the slide rail 11, a filter dehumidification filler 13 is arranged in the filling plate 12, and a push-pull handle 14 is installed at the edge of the filling plate 12.

[0023] On the basis of the above, when the compressed air passes through the filter dehumidification component inside the tank body 1, the water vapor and dust in the gas will be retained in the filter dehumidification filler 13. After a long period of accumulation, it will cause the filter dehumidification component to be blocked. At this time, the pressure inside the tank body 1 above the filter dehumidification component and the tank body 1 below the filter dehumidification component will change, and a pressure difference will appear in the upper and lower spaces. The two sensing tubes 5 of the differential pressure sensor 4 are respectively connected to the tank body 1 above the filter dehumidification component and the tank body 1 below the filter dehumidification component. When a pressure difference occurs, it will be detected by the differential pressure sensor 4. The user can use the pressure difference data detected by the differential pressure sensor 4 to replace and maintain the filter dehumidification component through the inspection door 6 at the appropriate time.

[0024] Furthermore, the filter dehumidification filler 13 is a mixture of wire mesh, suspended balls or other common filter dehumidification fillers 13. When disassembling the filter dehumidification component, the filling plate 12 can be pulled along the slide rail 11 by the push-pull handle 14, and the filling plate 12 can be pulled out from the slide rail 11 and moved from the inspection port to the outside of the tank body 1 to achieve replacement of the filter dehumidification component.

[0025] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
