Description

Technical Field

[0001] This invention relates to the field of alkaline washing and separation technology for R134a finished products, specifically to an alkaline washing and separation device for R134a finished products. Background Technology

[0002] Currently, in the R134a product separation process, after water washing, the R134a product and alkali solution are pumped into a decanter via a mixing pump. The existing decanter has a top feed, bottom discharge, and top alkali overflow outlet. In this process, the top straight pipe feed is prone to "liquid impact" and will also form fluid convection, which is not conducive to the formation of "stratification". In addition, there are still impurities inside the container after the existing R134a product is alkali washed, which will affect the effect of the next R134a product alkali washing. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an alkaline washing and separation device for R134a finished products. This device solves the problems mentioned in the background art, where existing decanters have top feeding, bottom discharging, and top alkali overflow. In this process, the top straight pipe feeding easily causes "liquid impact" and fluid convection, which is not conducive to the formation of "stratification". Furthermore, existing alkaline washing of R134a finished products leaves impurities inside the container, thus affecting the alkaline washing effect of the next R134a finished product.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an alkaline washing and separation device for R134a finished product, comprising a separation structure for alkaline washing of R134a finished product, wherein a diversion and conveying structure for diverting the mixed liquid is provided inside the separation structure, and the diversion and conveying structure is provided with a scraping structure for cleaning the components of the separation structure inside the separation structure.

[0005] The separation structure includes a hollow separation cylinder with a discharge pipe for easy discharge of the R134a finished product after alkali washing. A high-pressure liquid pump is provided above the discharge pipe to extract the R134a finished product. The high-pressure liquid pump has a flange delivery pipe on one side of the separation cylinder to facilitate the delivery of the mixed liquid into the separation cylinder. The flange delivery pipe has an outlet pipe on the other side above the separation cylinder to facilitate the overflow of the alkaline solution.

[0006] By adopting the above technical solution, the flange infusion pipe can achieve the effect of mixed liquid transportation and diversion transportation structure installation.

[0007] Preferably, the diversion and conveying structure includes a liquid distribution component installed with the flange liquid delivery pipe. The liquid distribution component is symmetrically provided with a liquid blocking component to reduce the liquid flow rate. The liquid distribution component includes a connecting block with a hollow structure in the middle. The connecting block has a through hole for easy installation of the flange connecting pipe. The through hole has an installation groove for easy installation of bearings.

[0008] By adopting the above technical solution, the connecting block can achieve the effect of opening and installing settings.

[0009] Preferably, the liquid separation assembly includes a flange connecting pipe, and a connecting plate with a hollow internal structure is embedded at the bottom of the flange connecting pipe. The connecting plate has multiple liquid separation holes symmetrically opened through it to facilitate the outflow and delivery of the mixed liquid.

[0010] By adopting the above technical solution, the mixing liquid can be diverted and transported through the connecting plate.

[0011] Preferably, the diversion and conveying structure includes a liquid-blocking assembly, which includes a connecting rod through which a through block is provided, and guide plates symmetrically provided at both ends of the connecting rod for guiding and conveying the mixed liquid. The guide plates are provided with a pressing rod that is subjected to pressure through the through block.

[0012] By adopting the above technical solution, the guide plate can guide and transport the mixed liquid and reduce the flow rate.

[0013] Preferably, the liquid-blocking assembly includes a squeezing rod, with connecting plates having through holes movably disposed on both sides of the squeezing rod, and the connecting plates being installed through the discharge pipe.

[0014] By adopting the above technical solution, the compression rod achieves the effects of installation, setting, and elastic recovery under stress.

[0015] Preferably, the scraping structure includes a connecting drive assembly for mounting the scraping component. The connecting drive assembly includes a hollow block with a connecting bearing inside. The hollow block is mounted to the inner ring of another connecting bearing via a connecting frame.

[0016] By adopting the above technical solution, the hollow block can achieve the effect of installation on both the inner and outer sides.

[0017] Preferably, the connection drive assembly includes a hollow block, which is installed on the drain plate via a fixing plate, and the drain plate is installed on the long shaft motor via a separation cylinder.

[0018] By adopting the above technical solution, the funnel plate can achieve the effects of installation on both sides and adjustment of force rotation.

[0019] Preferably, the scraping structure includes a scraping assembly, which includes a fixing frame mounted on the connecting frame, and the fixing frame is mounted on the scraper.

[0020] By adopting the above technical solution, the connecting frame not only serves as the mounting bracket at both ends but also provides force-bearing rotation adjustment for the fixed frame.

[0021] Preferably, the scraper is provided in two sets, and the scraper is rectangular and arc-shaped respectively.

[0022] By adopting the above technical solution, the scraper can achieve a force-driven rotating scraping effect on both the upper and lower parts of the separation cylinder.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the R134a finished product alkaline washing and separation device,

[0024] (1) The present invention solves the problem of "liquid impact" caused by straight pipe feeding and fluid convection, which is not conducive to the formation of "layering" by setting a liquid distribution component in the diversion conveying structure. When the mixed liquid is conveyed inside the flange connecting pipe, the mixed liquid conveyed inside the separation connecting pipe is conveyed inside the connecting plate. The mixed liquid entering the connecting plate falls into the separation cylinder through the liquid distribution hole. The flange connecting pipe, connecting plate and liquid distribution hole are used to avoid the above situation.

[0025] (2) By setting up a scraping structure, the problem of residual impurities in the container after the R134a finished product is solved, which affects the effect of the next R134a finished product alkali washing. After the R134a finished product is alkali washed, the Changzhong motor controls the force movement of the sluice plate. During the force movement of the sluice plate, the hollow block drives the connecting frame to move, and during the force movement of the connecting parts, the fixed frame drives the scraper to move in the same direction. During the force movement of the scraper, the residual impurities in the separation cylinder are scraped. The scraped impurities fall into the separation cylinder and are discharged through the discharge valve. The scraping structure not only avoids the above situation, but also avoids the situation of excessive accumulation of impurities, which increases the difficulty of cleaning.

[0026] (3) By using the liquid-blocking component in the diversion and conveying structure, the problem of the mixture fluctuating below the separation cylinder due to the excessive flow rate of the mixed liquid is solved, and the stratification effect of the mixed liquid is reduced. When the mixed liquid comes into contact with the guide plate, the guide plate is forced to move the connecting rod. During the movement of the connecting rod, the extrusion rod is forced to move through the through block. By changing the relative movement between the guide plates, the situation of the mixed liquid splashing easily when the pressure of the mixed liquid is large and it comes into contact with the guide plate is avoided. At the same time, the contact adjustment between the guide plate and the mixed liquid not only avoids the above situation, but also adapts to the mixed liquid under different pressures to reduce the contact speed effect.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-11 This invention provides a technical solution: an alkali washing and separation device for R134a finished product, such as... Figure 1 and Figure 2As shown, the separation structure 1 includes a separation cylinder 101 with a hollow internal structure. The separation cylinder 101 is provided with a discharge pipe 102 for easy discharge of the R134a finished product after alkali washing. A high-pressure liquid pump 103 is provided above the discharge pipe 102 to extract the R134a finished product. The high-pressure liquid pump 103 is provided with a flange delivery pipe 104 on one side of the separation cylinder 101 to facilitate the delivery of the mixed liquid into the separation cylinder 101. The flange delivery pipe 104 is provided with an outlet pipe 105 on the other side above the separation cylinder 101 to facilitate the overflow of alkaline solution. The components in the separation structure 1 are all designed using existing technology. The use of existing technology ensures the delivery of the mixed liquid and the installation effect of the components in the diversion and delivery structure 2. At the same time, an impurity discharge valve is provided at the bottom of the separation cylinder 101 to facilitate the rapid discharge of the cleaned impurities.

[0041] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the separation structure 1 is internally equipped with a diversion and conveying structure 2 for diverting the mixed liquid. The diversion and conveying structure 2 includes a liquid-distributing assembly 201 installed with the flange delivery pipe 104. The liquid-distributing assembly 201 is symmetrically equipped with a liquid-blocking assembly 202 to reduce the liquid flow rate. The liquid-distributing assembly 201 includes a connecting block 2011 with a hollow structure in the middle. The connecting block 2011 has a through hole for easy installation of the flange connection pipe 2012. The through hole has an installation groove for easy installation of bearings. The connecting block 2011 is shaped like a protractor. This not only demonstrates the practicality of the above-mentioned structural design, but also the through-opening connection and installation connection effect of the above-mentioned structural design. Furthermore, the flange connecting pipe 2012 is also installed using the flange connecting pipe 2012 in the existing technology structure. By using the existing flange connecting pipe 2012 in sequence, it not only achieves the installation and setting effect with the flange infusion pipe 104, but also effectively transports the mixed liquid into the connecting plate 2013 for liquid separation processing. In addition, there are two bearings installed. The symmetrical installation of the bearings facilitates the movement between the liquid blocking component 202 and the connecting block 2011.

[0042] Furthermore, the above-mentioned solution includes a flange connecting pipe 2012, with a hollow connecting plate 2013 embedded at the bottom of the flange connecting pipe 2012. The connecting plate 2013 has multiple symmetrically symmetrically opened dispensing holes 2014 to facilitate the outflow and transportation of the mixed liquid. The connecting plate 2013 is installed using ceramic material. Using ceramic material to install the connecting plate 2013 not only avoids corrosion of the connecting plate 2013 by alkaline solution over a long period of use, but also effectively extends the service life of the connecting plate 2013. At the same time, the connecting plate 2013 has 10 symmetrically opened dispensing holes 2014, which effectively divert and transport the mixed liquid transported inside the connecting plate 2013.

[0043] Further, the above scheme includes a diversion and conveying structure 2, which includes a liquid-blocking component 202. The liquid-blocking component 202 includes a connecting rod 2021 that passes through a through block 2022. The connecting rod 2021 has guide plates 2023 symmetrically arranged at both ends for guiding and conveying the mixed liquid. The guide plates 2023 are provided with a pressing rod 2024 that is subjected to pressure through the through block 2022.

[0044] Preferably, the connecting rod 2021 has an overall L-shaped structure. The L-shaped structure of the connecting rod 2021 not only matches the inner ring of the mounting bearing, but also facilitates the installation of the through block 2022 and the guide plate 2023. Furthermore, two guide plates 2023 are symmetrically arranged on a single connecting rod 2021, which provides a contact guiding and conveying effect for the mixed liquid.

[0045] Furthermore, the above solution includes a liquid-blocking assembly 202 comprising a squeezing rod 2024. Connecting plates 2025 with through holes are movably mounted on both sides of the squeezing rod 2024, and the connecting plates 2025 are installed through the discharge pipe 102. The squeezing rod 2024 is made of a shape-memory metal material with a protective film coating. Using this shape-memory metal material not only provides elastic recovery for the squeezing rod 2024 but also allows the guide plate 2023 to move under slight stress, thereby adjusting the force on the guide plate 2023.

[0046] In the above scheme, the operator's high-pressure liquid pump 103 delivers the mixed R134a and alkaline solution into the flange delivery pipe 104, which then enters the mixed liquid delivery flange connecting pipe 2012 inside the flange delivery pipe 104. The mixed liquid inside the flange connecting pipe 2012 is then delivered into the connecting plate 2013. The mixed liquid inside the connecting plate 2013 flows out through the distribution hole 2014. When the flow-out mixed liquid comes into contact with the guide plate 2023, the guide plate 2023 is forced to drive the connecting rod. 2021 and connecting block 2011 move relative to each other under force. During the movement of connecting block 2011 under force, the extrusion rod 2024 and connecting plate 2025 move relative to each other through the through block 2022. The guide plate 2023, which is in contact with the mixed liquid, transports the mixed liquid into the separation cylinder 101. At this time, when the mixed liquid transported into the separation cylinder 101 is in a static stratified state, the used alkaline solution is discharged from the liquid outlet pipe 105, and the R134a after alkaline washing is discharged by the high-pressure liquid pump 103 through the discharge pipe 102.

[0047] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the diversion and conveying structure 2 has a scraping structure 3 inside the separation structure 1 for cleaning the components of the separation structure 1. The scraping structure 3 includes a connecting drive assembly 301 for mounting the scraping assembly 302. The connecting drive assembly 301 includes a hollow block 3011 with a connecting bearing 3012 inside. The hollow block 3011 is installed with the inner ring of another connecting bearing 3012 through a connecting frame 3013. There are two connecting bearings 3012, and the two connecting bearings 3012 are set with connecting bearings 3012 of different diameters. Using connecting bearings 3012 of different diameters not only facilitates the installation of connecting bearings 3012 with the hollow block 3011, but also facilitates the installation with the lower part of the separation cylinder 101. At the same time, the connecting bearings 3012 are ceramic bearings in the existing technology structure. The use of ceramic bearings effectively extends the service life of the connecting bearings 3012.

[0048] Furthermore, the above-mentioned solution includes a hollow block 3011 connected to the drive assembly 3011. The hollow block 3011 is installed on the slotted plate 3014 via a fixing plate, and the slotted plate 3014 is installed on the long shaft motor 3015 via a separation cylinder 101. The slotted plate 3014 not only serves as an installation device but also facilitates the rotation and adjustment of the hollow block 3011.

[0049] Further, the above scheme includes a scraping structure 3 comprising a scraping component 302, which includes a fixing frame 3021 installed with the connecting frame 3013. The fixing frame 3021 is installed with scraper 3022. There are two sets of scraper 3022, which are rectangular and arc-shaped respectively. When four scraper 3022 are provided, it not only reflects the practicality of the above structure, but also the installation connection and scraping effect of the above structure. At the same time, by providing four scraper 3022, the coaxial driving and unidirectional force scraping effect of the above structure are reflected. Furthermore, when the scraper 3022 is rectangular and arc-shaped respectively, it is to better fit the inner wall and bottom of the separation cylinder 101, thereby achieving a rotational scraping effect inside the separation cylinder 101.

[0050] In the above scheme, when impurities remain inside the separator 101, the operator controls the long-shaft motor 3015 to work. During the operation of the long-shaft motor 3015, the hollow block 3011 is driven to move under force through the funnel 3014. During the movement of the hollow block 3011 under force, the fixed frame 3021 is driven to rotate under force through the connecting frame 3013. During the rotation of the fixed frame 3021 under force, the scraper 3022 is driven to rotate under force. During the rotation of the scraper 3022 under force, the impurities remaining inside the separator 101 are scraped off. At the same time, the discharge valve is opened to discharge the impurities from the separator 101.
