Description

Technical Field

[0001] The utility model relates to the technical field of storage, and more specifically, to a chemical storage tank with a recovery function. Background Art

[0002] BDO is an industrial product, with the professional name of 1,4-butanediol. It is a colorless oily liquid, non-volatile at normal temperature, and easily condenses below 25 degrees Celsius. BDO can be miscible with water, and can also dissolve in methanol, ethanol, and propanol, but is only slightly soluble in ether. It has a relatively high boiling point and a relatively low melting point. In petrochemical industry, BDO, as an organic chemical raw material and fine chemical raw material, plays a very important role and has a wide range of applications, not only in engineering plastics, fibers, but also in solvents, etc. In petrochemical industry, storage tanks are the main components of the current petrochemical production line, and their main function is to store liquid BDO chemical materials. At present, in order to reduce the volatilization loss of BDO liquid materials, it is often necessary to recover the volatilized BDO.

[0003] For example, the patent with the publication number CN204447372U discloses a chemical storage tank with a recovery function, which includes several storage tank bodies. Above the several storage tank bodies, they are all connected to the air inlet of the condenser through a material guiding pipe. A fan is provided at the air outlet of the condenser. The reflux port of the condenser is connected to the inside of the storage tank body through a reflux pipe. The cooling pipeline connection port of the condenser is connected to the cooling water system through a pipeline. This utility model overcomes the deficiencies of the prior art, has a reasonable design structure, uses the suction force of the fan to lead the emptied materials of each storage tank to the condenser, uses circulating water to condense the emptied materials, and the condensed liquid materials flow back to the storage tank. When the material is an easily solidifiable material, steam tracing and insulation need to be added to the material emptying pipeline and the pipeline for the condensed material to fall.

[0004] In the above patent, the inventor believes that when this patent is in use, although it satisfies the recovery function of material volatilization, there is a problem of high recovery cost in using a condenser to condense the material into a liquid for recovery. Content of the Utility Model

Specific embodiments

[0021] The following specific embodiments illustrate the embodiments of the present utility model. Those familiar with this technology can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] With reference to Figures 1 - 4, the present utility model provides a chemical storage tank with a recycling function, including a bracket 1, a storage tank body 2 arranged on the bracket 1, and an emptying pipe 3 connected to the storage tank body 2. The top of the emptying pipe 3 is rotatably connected to a pipe cover 4 through a hinge. In this setting, the pipe cover 4 can be connected to the emptying pipe 3 through existing locks such as (furnace lock type), and the lock is not shown in the figure. A telescopic device 5 is arranged on the top of the pipe cover 4, and an active pressing plate 6 is arranged at the bottom of the pipe cover 4. The active pressing plate 6 is fixedly connected to the output end of the telescopic device 5. The pipe cover 4 is rotatably arranged on the emptying pipe 3 through a hinge to meet the adjustment of the positions of the telescopic device 5 and the active pressing plate 6, so as to provide an effective operating space for the lumen of the emptying pipe 3. An air-permeable support plate 7 is fixedly connected inside the emptying pipe 3, and a moisture-absorbing filter element 8 is movably arranged on the top of the air-permeable support plate 7. The moisture-absorbing filter element 8 can be made of absorbent cotton and is arranged in a columnar structure. An air-permeable pressing plate 9 movably connected to the active pressing plate 6 is arranged on the top of the moisture-absorbing filter element 8, and the air-permeable pressing plate 9 is slidably connected inside the emptying pipe 3. A conventional seal can be used on the periphery of the air-permeable pressing plate 9 to achieve sliding seal inside the emptying pipe 3, and its sliding in the emptying pipe 3 is like the movement effect of a piston in a compressor. An elastic resetting member 11 is arranged on the air-permeable support plate 7, and the elastic resetting member 11 is movably connected to the air-permeable pressing plate 9. An exhaust pipe 10 is connected to the emptying pipe 3, and the exhaust pipe 10 can provide a gas discharge channel for the volatilization of BDO material in the storage tank body 2.

[0023] The output end of the telescopic device 5 penetrates through the pipe cover 4 and is connected to the active pressing plate 6. The telescopic device 5 can adopt a telescopic motor, which can drive the active pressing plate 6 to move vertically inside the emptying pipe 3.

[0024] An air hole one 71 is opened on the air-permeable support plate 7, and an air hole two 91 is opened on the air-permeable pressing plate 9. The settings of the air hole one 71 and the air hole two 91 can increase air permeability. The air hole one 71 can provide a channel for the volatilized BDO material in the storage tank body 2, and the air hole two 91 can play an exhaust role for the volatilized material of the moisture-absorbed BDO material. In this application, both the air hole two 91 and the air hole one 71 are provided with multiple ones. The multiple air hole two 91 can enclose an air hole area, and the air hole area is smaller than the size of the active pressing plate 6. When the active pressing plate 6 presses on the air-permeable pressing plate 9, it can relatively block the air hole area, so as to avoid the liquid BDO material being discharged through the air hole two 91 when the moisture-absorbing filter element 8 is compressed.

[0025] The elastic resetting member 11 includes a sleeve 111 fixedly connected to the bottom of the air-permeable support plate 7, a T-shaped sliding rod 112 slidably connected inside the sleeve 111, and a tension spring 113 arranged inside the sleeve 111. One end of the tension spring 113 is movably abutted against one end of the T-shaped sliding rod 112. In this application, a T-shaped cavity is arranged inside the sleeve 111, which can be used for the sliding and limiting of the T-shaped sliding rod 112.

[0026] The other end of the T-shaped slide bar 112 sequentially passes through the breathable support plate 7 and the moisture absorption filter element 8 movably, and the other end of the T-shaped slide bar 112 is in movable contact with the bottom of the breathable pressing plate 9.

[0027] Specifically, when the breathable pressing plate 9 compresses the moisture absorption filter element 8, the downward pressing action of the breathable pressing plate 9 can control the T-shaped slide bar 112 to descend and slide in the sleeve 111, and at the same time, the tension spring 113 is in a compressed state. Until the breathable pressing plate 9 releases the pressure on the T-shaped slide bar 112, the elastic force of the tension spring 113 can make the breathable pressing plate 9 reset and move upward.

[0028] One end of the exhaust pipe 10 is provided with an exhaust fan 12, and a filter screen 13 is provided at the exhaust end of the exhaust fan 12. The exhaust fan 12 can facilitate the extraction of the volatilized BDO material in the storage tank body 2, so as to prevent the storage tank body 2 from being suffocated and deformed and damaged. The filter screen 13 can provide dust protection for the port of the exhaust fan 12, that is, provide dust protection for the storage tank body 2.

[0029] In this embodiment, by covering the pipe cap 4 on the drain pipe 3, the active pressing plate 6 is arranged in the lumen of the drain pipe 3. Then, the exhaust fan 12 can be started to extract the volatilized BDO material in the storage tank body 2. The volatilized material can enter through the air hole 71, pass through the moisture absorption filter element 8. The moisture absorption filter element 8 can inhale the liquid components of the volatilized BDO material and allow the gas to pass through. The gas is then discharged through the exhaust pipe 10 at the position of the air hole 91. This can facilitate the retention of the liquid component of the BDO material. Then, the telescopic device 5 can be driven to drive the active pressing plate 6 to descend. The downward pressing action of the active pressing plate 6 can control the breathable pressing plate 9 to move downward. Then, the breathable pressing plate 9 can squeeze the moisture absorption filter element 8. At this time, the T-shaped slide bar 112 is pressed into the sleeve 111, and at the same time, the tension spring 113 is in a compressed state. In this way, the liquid BDO material absorbed by the moisture absorption filter element 8 can be recovered to the storage tank body 2 through the position of the air hole 71, and the recovery cost is low. Until the telescopic device 5 resets and contracts, by the elastic force of the tension spring 113, it can push the breathable pressing plate 9 upward through the T-shaped slide bar 112 to reset the compressed position of the breathable pressing plate 9, so as to facilitate the subsequent compression treatment of the moisture absorption filter element 8.

[0030] It should be noted that because the active pressing plate 6 and the breathable pressing plate 9 adopt a contact control method, and because the breathable pressing plate 9 is movably arranged on the moisture absorption filter element 8, by opening the pipe cap 4 and removing the active pressing plate 6, by reserving an operation area at the top of the drain pipe 3, it is convenient to take out the moisture absorption filter element 8 for replacement.
