Description

Technical Field

[0001] The utility model belongs to the technical field of waste liquid recovery equipment, and mainly relates to a device for recycling and reusing 1,1-dichloro-1-fluoroethane waste liquid. Background Art

[0002] 1,1-dichloro-1-fluoroethane is a high-purity liquid, which is widely used in the fields of cleaning and solvents. Since its impact on the ozone layer is very small, it is designated as an ideal substitute for fully halogenated chlorofluorocarbons. At present, after cleaning with 1,1-dichloro-1-fluoroethane cleaning agent, the waste liquid will be mixed with grease (mainly wide-temperature grease), particulate impurities (mainly hard rubber particles, metal chips), etc. In the past, the waste liquid was handed over to a professional company for recycling, but the problems brought are that the utilization rate of 1,1-dichloro-1-fluoroethane cleaning agent in this unit is low, it cannot be reused, and the cost is high.

[0003] In the patent application No. CN201410496603.5, a method for recycling and reusing waste liquid of waterborne coating cleaning agent is disclosed. The waste liquid of waterborne coating cleaning agent is pretreated for classification and removal of foreign matters, and then additive A and additive B are added to carry out a demulsification reaction to form a mixture of paint sludge and solution; after the waste liquid demulsification reaction is complete, it enters the filtration system for solid-liquid separation to completely separate the solution and the paint sludge; the paint sludge is treated harmlessly; the solution is subjected to solvent enrichment to separate a small amount of water from the mixture of most solvents; the separated wastewater meets the discharge standards after wastewater treatment, and the solvent mixture enters the solvent purification process, and the separated wastewater meets the discharge standards after wastewater treatment. However, the waste liquid recycling and reusing method of this application requires all the equipment used to consume electricity and be reused on a large scale, and other chemical substances need to be added for separation. This recycling and reusing scheme cannot achieve energy-saving effects, and has the disadvantages of low utilization rate and high operation cost, which is not conducive to the long-term development of enterprises.

[0016] The present utility model will be described in conjunction with the accompanying drawings.

[0017] As Figure 1As shown in the figure, a device for recycling and reusing 1,1-dichloro-1-fluoroethane waste liquid includes a waste liquid tank 1. The interior of the waste liquid tank 1 has a cavity structure. After the waste liquid is poured into the waste liquid tank 1 and left standing, the waste liquid is stratified. The waste liquid in the tank is divided into three layers. The upper layer is the floating oil layer 2, the middle layer is the clean layer 3, and the lower layer is the particle layer 4. An observation window 5 and an air filter 6 are respectively arranged at the top of the waste liquid tank 1. A waste liquid outlet 7 communicating with the waste liquid tank 1 is arranged on one side of the bottom of the waste liquid tank 1. A collector 8 communicating with the waste liquid tank 1 is arranged outside the waste liquid tank 1. A recovery component is also arranged inside the tank body of the waste liquid tank 1.

[0018] The recovery component includes a floating rod 9 horizontally arranged in the upper part of the waste liquid tank 1. One end of the floating rod 9 is hinged to the inner wall of the waste liquid tank 1, and a floating ball 10 is hinged to the other end. And a vertically arranged vertical rod 11 is hinged in the middle of the floating rod 9. Here, the hinged connection method is adopted, and both the floating rod 9 and the vertical rod 11 can rotate around the joint. The bottom surface of the floating ball 10 is attached to the top surface of the floating oil layer 2 and can move up and down as the waste liquid rises and falls, which can intuitively observe the discharge situation of the liquid in the waste liquid tank 1, facilitating high efficiency. The lower end of the vertical rod 11 is connected with a plastic hose 12. The outlet end of the plastic hose 12 communicates with the inlet end of a discharge hard pipe 13 arranged at the bottom of the waste liquid tank 1. The liquid inlet end 18 of the plastic hose 12 is arranged at the joint with the lower end of the vertical rod 11, and the plastic hose 12 is located in the clean layer 3.

[0019] The discharge hard pipe 13 is arranged in the upper part of the particle layer 4, and the outlet end of the discharge hard pipe 13 communicates with the collector 8. And a switch 14 is arranged on the pipe body of the discharge hard pipe 13, and a filter screen 15 is also arranged in the pipe body. The switch 14 arranged here is used to control the discharge of the waste liquid in the clean layer 3. The filter screen is used for fine filtering of the flowing cleaning agent. After filtering, the clean 1,1-dichloro-1-fluoroethane flows into the collector for reuse in the re-cleaning of products, while the remaining floating oil layer, particle layer and part of the middle clean layer are finally handed over for waste treatment. A limit block 16 is also arranged at the lower part of the floating rod 9. The limit block 16 is fixedly connected to the inner wall surface of the waste liquid tank 1. The limit block 16 arranged here is used to resist and limit the maximum angle of the downward rotation of the floating rod 9, thereby preventing the liquid inlet end 18 connected to the plastic hose 12 connected below it from being lowered into the particle layer 4. A movable guide wheel 17 is also arranged at the bottom of the waste liquid tank 1. By arranging the guide wheel 17, the waste liquid tank 1 can be moved flexibly and conveniently, improving the use efficiency.

[0020] When the utility model is in use, the distance between the hinge point on the left side of the vertical rod 11 and the floating rod 9 is set as "l", the distance between the hinge point of the floating ball 10 and the hinge point on the left side of the floating rod 9 is "L", the height of the liquid inlet end 18 from the bottom of the waste liquid tank 1 is "h", and the height of the top of the floating oil layer 2 from the bottom of the waste liquid tank 1 is "H"; assuming that the falling distance of the floating ball 10 is "a", then the liquid level height H1 = H - a, and at this time the height h1 of the liquid inlet end 18 = h - a / 2 = H / 2 - a / 2 = (H - a) / 2 = H1 / 2, that is, when the floating ball falls a distance a, the height h1 of the liquid inlet end 18 still remains half of the liquid level height H1; by using the principle of pressure difference, it can be ensured that the waste liquid entering the collector 8 from the liquid inlet end 18 is the waste liquid in the clean layer 3 during the recovery process; when the waste liquid in the clean layer 3 continuously passes through the filter screen 15 and enters the collector 8, the waste liquid height of the floating oil layer 2 continuously decreases, and the liquid level drop situation can be visually observed through the floating ball 10 until the floating rod 9 touches the limit block 16. At this time, due to the set height difference and the principle of pressure difference, the waste liquid in the clean layer 3 basically stops discharging, and at this time, the switch 14 can be closed to stop the discharge.

[0021] The preferred embodiments of the present utility model have been described in detail above, but the present utility model is not limited to the specific details in the above embodiments. Within the technical concept scope of the present utility model, various equivalent transformations can be made to the technical solutions of the present utility model, and these equivalent transformations all belong to the protection scope of the present utility model.
