Problems solved by technology

[0003] 1. A large number of chemical manufacturers still use manual dehydration of storage tanks, which is not only labor-intensive, but also inefficient; some companies also use float-type automatic dehydration devices, which can also achieve automatic dehydration effects, but the volume of the float must be designed to be relatively small Larger buoyancy can pull up the valve shaft and open the valve. The whole structure is cumbersome, and sometimes the valve cannot be opened. There is also a storage tank automatic dehydrator in the prior art. The storage tank automatic dehydrator can Realize automatic dehydration, but the automatic dehydrator of the storage tank is only equipped with a drain valve and installed in the sedimentation water storage tank, which is prone to blockage after a long working time, and has disadvantages such as inconvenient cleaning, which cannot meet the needs of efficient and rapid production; The more serious point is that because the whole set of equipment is installed in the sedimentation water storage tank, it is easy to cause foreign objects in the equipment, such as welding slag, iron filings, etc., to make the valve not closed tightly, resulting in medium leakage and production accidents.
[0004] 2. The sealing performance of the existing automatic dehydration device for storage tanks is not good, and it is easy to cause the medium in the storage tank to leak and discharge, which not only causes waste of raw materials but also pollutes the environment, and at the same time brings great safety hazards to workers, which cannot meet the needs of safe and green production needs
[0005] 3. The dehydration device cannot achieve double interlocking, and it is easy to cause mis-drainage when the valve is damaged, hinder production, cause shutdown for maintenance, and reduce production efficiency
[0006] 4. When the pipes are blocked by dirt, there are problems of cumbersome maintenance and difficult dredging and cleaning

specific Embodiment approach

[0032] The specific implementation is as follows, below the discharge port 13 is a four-way pipeline, the upper opening is connected to the discharge port 13, the lower opening is provided with a sewage plug 74, the left horizontal opening is installed in series with a drain valve 71 and an air-closing valve 72, and the right horizontal opening Install manual drain valve 73.

[0033]The liquid level linkage device 5 includes a floating ball 51 and a buoyancy lever 52. The floating ball 51 floats on the liquid level in the sedimentation water storage tank 1, and can change its height according to the rising and falling of the liquid level. The upper end of the floating ball 51 is movably connected to the end of the buoyancy lever 52 , and the other end of the buoyancy lever 52 extends into the inside of the sealing chamber 3 and is movably connected to the rotating shaft 6 .

[0034] The valve control device 4 is composed of a high interface pneumatic switching valve 41, a low ...

Abstract

The invention discloses a pneumatic double-storage-tank drainage controller, and belongs to the field of storage tank equipment in the chemical industry. The pneumatic double-storage-tank drainage controller is characterized in that a drain valve (71) is an air-to-open valve, and an air-to-close valve (72) is mounted on one side of the drain valve (71) in a serial connection manner; and a liquid level linkage device (5) extends out of a side wall of a sediment water storage tank (1) and is movably connected with a valve control device (4) by a rotary shaft (6), and the valve control device (4) is mounted on the outside of the sediment water storage tank (1), is connected with the drain valve (71) and the air-to-close valve (72) and can drive the drain valve (71) to be opened to drain water or drive the air-to-close valve (72) to be closed to prevent the water or media from flowing out respectively according to the liquid level of the inside of the sediment water storage tank (1). The pneumatic double-storage-tank drainage controller has the advantages that storage tanks can be automatically drained, the work efficiency is improved, a sealing effect is good, leakage of the media can be completely eradicated, and environments and the life safety of workers are protected.

Description

technical field [0001] A pneumatic duplex storage tank dehydration controller belongs to the field of storage tank equipment in the chemical industry, and specifically relates to a storage tank dehydration controller. Background technique [0002] Storage tanks are essential equipment in the chemical industry. With the rapid development of the chemical industry, the storage tank dehydration methods under the existing technology are gradually unable to meet the production needs due to their own structural limitations, which are mainly manifested in the following aspects: [0003] 1. A large number of chemical manufacturers still use manual dehydration of storage tanks, which is not only labor-intensive, but also inefficient; some companies also use float-type automatic dehydration devices, which can also achieve automatic dehydration effects, but the volume of the float must be designed to be relatively small Larger buoyancy can pull up the valve shaft and open the valve.
