Description
Technical Field
[0001] This utility model belongs to the field of tetrabromoethane technology, and in particular relates to an acetone filtration device for tetrabromoethane. Background Technology
[0002] Tetrabromoethane is an organohalogenated compound with the chemical formula C2H2Br4. It is a colorless or pale yellow liquid at room temperature with a chloroform-like odor. It is insoluble in water but readily soluble in organic solvents such as ethanol and ether. It can be prepared by the addition reaction of acetylene with bromine. It has high density and stability. In the industrial field, tetrabromoethane has been used as a solvent, flame retardant additive, and organic synthesis intermediate.
[0003] Currently, our acetylene gasification process utilizes a water-sealed tank on the gasification pipeline to wash acetone from the acetylene. This method has poor removal efficiency. The boiling point of the acetone-water mixture is lower than that of pure water, making it easily volatile and entering the synthesis reaction system, generating byproducts and affecting the quality and conversion rate of the finished product. Due to its volatility, the washing water in the water-sealed tank needs to be frequently replaced, generating wastewater and increasing the amount of sewage to be treated. Therefore, we need to design an acetone filtration device for tetrabromoethane. This device efficiently separates acetone from acetylene through an acetone filter, reducing byproduct formation and significantly improving the quality and conversion rate of tetrabromoethane. It is equipped with a backflushing cleaning function to facilitate filter maintenance. Combined with a water tank, it enhances the separation effect of acetone and acetylene, greatly reducing the amount of washing water discharged, lowering the amount of sewage to be treated, avoiding the problem of frequent water changes in traditional water-sealed tanks, achieving green and environmentally friendly production, and balancing production efficiency with environmental protection requirements. Utility Model Content

The outlet of the punch is symmetrical with the filter screen. A circular plate is provided on the top of the connector. A lower locking tooth is fixedly connected to the top of the circular plate. An upper locking tooth is provided on the surface of the connecting pipe. The upper locking tooth engages with the lower locking tooth. A ball valve is installed above the surface of the connecting pipe.
[0006] Preferably, a sealing gasket is fixedly installed on the top of the connector, and the side of the sealing gasket away from the connector is fixedly connected to the disc.
[0007] Preferably, a connecting sleeve is slidably connected to the surface of the connecting pipe, and the surface of the connecting sleeve is provided with multiple grooves.
[0008] Preferably, the inner cavity of the upper tooth is fixedly connected with a plurality of sliding blocks, and the plurality of sliding blocks are slidably connected to the sliding groove.
[0009] Preferably, the surface of the connecting pipe is threaded with a force-applying handle, and the bottom of the force-applying handle is tightly fitted with the top of the upper clamping tooth.
[0010] The beneficial effects of this utility model are: 1.

By setting a sealing gasket, the sealing gasket at the connection between the connector and the disc can tightly fill the gap between the components, block the gas and liquid leakage channels, prevent acetylene leakage or external impurities from seeping into the acetone filtration system, and ensure production safety and filtration effect. 3. This utility model uses the cooperation of the groove and the sliding block so that when the upper locking tooth drives the sliding block to slide on the surface of the groove, the groove plays a guiding role for the sliding block, ensuring that the sliding block will not deviate during sliding, and improving the stability of the upper locking tooth sliding on the surface of the connecting sleeve.

Detailed Implementation
[0013] In the following description, embodiments of the tetrabromoethane acetone filtration device of the present invention will be described with reference to the accompanying drawings.
[0014] Figure 1-4 This invention illustrates an embodiment of an acetone filtration device for tetrabromoethane, comprising an acetone filter 2 connected to the surface of a pipe 1, a filter screen 3 installed inside the acetone filter 2, a connector 4 fixedly connected to the top of the pipe 1 by a sealing gasket, a connecting pipe 5 penetrating through the central axis of the connector 4, the connecting pipe 5 penetrating into the inner cavity of the pipe 1 and connected to a punch 6, the outlet of the punch 6 being symmetrical to the filter screen 3, a circular plate 8 provided on the top of the connector 4, and a sealing gasket 7 fixedly installed on the top of the connector 4, the side of the sealing gasket 7 away from the connector 4 being fixedly connected to the circular plate 8. Through the setting of the sealing gasket 7, the sealing gasket at the connection between the connector 4 and the circular plate 8 can tightly fill the gap between the components, blocking the gas and liquid leakage channels, preventing acetylene leakage or external impurities from seeping into the acetone filtration system, ensuring production safety and filtration effect. The top of the circular plate 8... The connecting pipe 5 is fixedly connected to a lower locking tooth 9. A connecting sleeve 10 is slidably connected to the surface of the connecting pipe 5. Multiple sliding grooves 11 are opened on the surface of the connecting sleeve 10. An upper locking tooth 12 is provided on the surface of the connecting pipe 5. Multiple sliding blocks 13 are fixedly connected to the inner cavity of the upper locking tooth 12. The multiple sliding blocks 13 are slidably connected to the sliding grooves 11. Through the cooperation of the sliding grooves 11 and the sliding blocks 13, when the upper locking tooth 12 drives the sliding blocks 13 to slide on the surface of the sliding grooves 11, the sliding grooves 11 play a guiding role for the sliding blocks 13, ensuring that the sliding blocks 13 will not deviate when sliding, and improving the stability of the upper locking tooth 12 sliding on the surface of the connecting sleeve 10. A force-applying handle 14 is threadedly connected to the surface of the connecting pipe 5. The bottom of the force-applying handle 14 is tightly fitted with the top of the upper locking tooth 12. The upper locking tooth 12 is engaged with the lower locking tooth 9. A ball valve 15 is installed on the upper surface of the connecting pipe 5.
[0015] Working Principle: In use, the device uses pipe 1 as the acetylene delivery channel. When acetylene gas containing acetone flows through pipe 1, it enters the inner cavity of acetone filter 2. The filter screen 3 inside the filter intercepts acetone impurities in the acetylene, achieving separation of acetylene and acetone. This prevents acetone from entering the subsequent synthesis reaction system with the acetylene, generating byproducts and ensuring the quality and conversion rate of tetrabromoethane. When the filter screen 3 becomes clogged with impurities and its filtration efficiency decreases after long-term use, it is backflushed and cleaned. First, rotate the force-applying handle 14 on the surface of the connecting pipe 5. The force-applying handle 14 pushes the upper locking tooth 12 down along the connecting sleeve 10 through threaded transmission. At this time, the sliding of the inner cavity of the upper locking tooth 12... Block 13 slides stably along the groove 11 on the surface of the connecting sleeve 10, ensuring that the upper locking tooth 12 accurately engages with the lower locking tooth 9 on the top disc 8 of the connector 4, so that the connecting pipe 5 and the bottom punch 6 are firmly positioned. The outlet of the punch 6 is precisely aligned with the filter screen 3. The top of the connecting pipe 5 is connected to a clean water source, and the ball valve 15 on the surface of the pipe 5 is opened. Clean water is transported to the punch 6 through the connecting pipe 5 and sprayed out by the punch 6 to backwash the filter screen 3, removing the impurities trapped by the filter screen. At the same time, the sealing gasket 7 between the connector 4 and the disc 8, and the sealing gasket between the pipe 1 and the connector 4 can tightly fill the gaps between the components, achieving the unity of acetone removal, low wastewater discharge and stable production.
[0016] In summary, this acetone filtration device for tetrabromoethane, through the coordinated use of the force-applying handle 14, upper clamping teeth 12, and lower clamping teeth 9, allows the connecting pipe 5 to drive the punch 6 stably through the inner cavity of the pipe 1, with the connector pointing towards the filter screen 3. Then, water is connected to the top of the connecting pipe 5, and the ball valve 15 is opened. Water flows through the inner cavity of the connecting pipe 5 to flush the filter screen 3, thereby reducing the generation of by-products, significantly improving the quality and conversion rate of tetrabromoethane, and facilitating filter maintenance with a backwash cleaning function. Combined with a water tank, it enhances the separation effect of acetone and acetylene, significantly reducing the amount of washing water discharged and lowering the wastewater treatment volume.
