It is easily soluble in hot ethanol, soluble in ether, benzene and carbon disulfide, slightly soluble in cold ethanol, and almost insoluble in water. It is a highly toxic substance. Due to its insolubility in water, water washing is usually used to remove impurities and clean it during production.

[0003] Due to the toxicity of dinitrochlorobenzene, it needs to be washed with water multiple times.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0024] The preferred embodiment of the 2,4-dinitrochlorobenzene water washing and recycling device provided by the utility model is as follows: Figures 1 to 4 As shown: A 2,4-dinitrochlorobenzene water washing and recycling device includes a base 1, a processing mechanism 2 is provided on the top of the base 1, and the processing mechanism 2 includes a stirring component 21 and a circulation component 22;

[0025] The stirring assembly 21 includes a cleaning tank 211, a feed port 212, a water injection port 213, a motor 214, a stirring rod 215 and a blocking plate 216;

[0026] The circulation assembly 22 includes a first conduit 221 , a drainage trough 222 , a second conduit 223 , a sump 224 , a circulation pipe 225 , a first liquid pump 226 , and a second liquid pump 227 .

[0027] In this embodiment, the cleaning tank 211 is fixedly connected to the top of the base 1, the left side of the cleaning tank 211 is fixedly connected to the feed port 212, the right side of the cleaning tank 211 is fixedly connected to the water injection port 213, the top of the cleaning tank 211 is fixedly connected to the motor 214, the output end of the motor 214 is fixedly connected to the stirring rod 215 located inside the cleaning tank 211, and the bottom of the cleaning tank 211 is threadedly connected to a sealing plate 216. The dinitrochlorobenzene to be cleaned is put into the interior of the cleaning tank 211 from the inside of the feed port 212, and then the cleaning water is injected into the interior of the cleaning tank 211 through the water injection port 213. The motor 214 is turned on to control the stirring rod 215 to rotate. When it rotates, the dinitrochlorobenzene will be stirred so that it can be cleaned more fully.

[0028] In this embodiment, a first liquid pump 226 is fixedly connected to the left side of the cleaning tank 211, a first conduit 221 is fixedly connected to the side of the first liquid pump 226, a tail of the first conduit 221 is fixedly connected to a drainage trough 222 fixedly connected to the base 1, a second liquid pump 227 fixedly connected to the right side of the cleaning tank 211 is provided on one side of the first conduit 221, a second conduit 223 is fixedly connected to the side of the second liquid pump 227, a tail of the second conduit 223 is fixedly connected to a water collection tank 224 fixedly connected to the base 1, and a circulation pipe 225 fixedly connected to the cleaning tank 211 is fixedly connected to the top of the water collection tank 224. During the last two cleanings, the cleaning water can be discharged into the interior of the water collection tank 224 through the second conduit 223 for temporary storage. When the next batch of dinitrochlorobenzene is cleaned, the water temporarily stored in the water collection tank 224 can be injected into the interior of the cleaning tank 211 through the water pump inside the water collection tank 224 and the circulation pipe 225, as the water source for the first cleaning before dinitrochlorobenzene, thereby improving resource utilization.

[0029] In this embodiment, the top of the sealing plate 216 is flush with the bottom inner wall of the cleaning tank 211, and the bottom of the cleaning tank 211 forms a closed structure through the sealing plate 216. The flush setting of the sealing plate 216 can facilitate the dinitrochlorobenzene to be spread flatly at the bottom of the cleaning tank 211 during cleaning.

[0030] In this embodiment, a water pump connected to a circulation pipe 225 is provided inside the water collection tank 224. The circulation pipe 225 passes through the cleaning tank 211 and extends into the interior thereof, so that the water temporarily stored inside the water collection tank 224 is injected into the interior of the cleaning tank 211 through the water pump inside the water collection tank 224 and the circulation pipe 225, and serves as the water source for the first cleaning before dinitrochlorobenzene. Example 2

[0031] On the basis of Example 1, the preferred embodiment of the 2,4-dinitrochlorobenzene water washing and recycling device provided by the present invention is as follows: Figures 1 to 4As shown: the surface of the drainage groove 222 is fixedly connected to a drain outlet 3, the top of the drain outlet 3 is rotatably connected to a valve 4, the top of the drainage groove 222 is fixedly connected to a limit plate 5, the inside of the limit plate 5 is slidably connected to a slider 6, and the surface of the slider 6 is fixedly connected to a placement plate 7 extending to the inside of the drainage groove 222.

[0032] In this embodiment, the surface of the placement plate 7 is provided with mesh-like through holes arranged at equal intervals, and the medicine will be evenly sprinkled on different positions of the water through the concave holes provided on the surface.

[0033] In this embodiment, transverse sliding grooves are provided inside the limiting plate 5 and the drainage groove 222, and the slider 6 and the limiting plate 5 are connected in a snap-fitting sliding manner. Chemical agents can be sprinkled into the placement plate 7, and then the placement plate 7 can be slid left and right along the limiting plate 5 so that the agents can be evenly sprinkled.

[0034] The working principle and use process of the present invention are as follows: first, the dinitrochlorobenzene to be cleaned is put into the inside of the cleaning tank 211 from the inside of the feed port 212, and then the cleaning water is injected into the inside of the cleaning tank 211 through the water injection port 213, and the motor 214 is turned on to control the stirring rod 215 to rotate. When it rotates, the dinitrochlorobenzene is stirred to make it more fully cleaned. After cleaning once, since the specific gravity of dinitro is greater than that of water, the dinitrochlorobenzene will settle down. At this time, the first liquid pump 226 can be turned on to discharge the cleaned water into the inside of the drainage trough 222, and then Then, water is injected again from the water injection port 213 to clean the dinitrochlorobenzene. The water from the previous cleanings is discharged into the drainage tank 222 through the first conduit 221 for temporary storage. During the last two cleanings, the cleaning water can be turned on the second liquid pump 227 and discharged into the sump 224 through the second conduit 223 for temporary storage. When cleaning the next batch of dinitrochlorobenzene, the water temporarily stored in the sump 224 can be injected into the cleaning tank 211 through the water pump inside the sump 224 and the circulation pipe 225, and used as the water source for the first cleaning of dinitrochlorobenzene, thereby improving resource utilization.

[0035] Since the wastewater from the first two dinitrochlorobenzene cleanings contains a relatively large amount of dinitrochlorobenzene impurities, which are harmful and cannot be discharged immediately, chemicals can be sprinkled into the inside of the placement plate 7, and then the placement plate 7 is slid left and right along the limit plate 5. When the placement plate 7 slides, the chemicals will pass through the concave holes set on its surface and be evenly sprinkled at different positions of the water, so that the chemicals can fully react with the wastewater and reduce its harmfulness. Finally, the wastewater can be discharged from the inside of the drain outlet 3 by opening the valve 4.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
