Description

Technical Field

[0001] This utility model relates to the field of new energy battery production technology, and in particular to a condensate recovery device. Background Technology

[0002] N-Methylpyrrolidone (NMP) is a colorless, transparent, oily liquid with a melting point of -24.4℃, a boiling point of 203℃, and a flash point of 95℃. It is a high-performance, strongly polar, aprotic solvent with excellent chemical stability, high temperature resistance, strong solubility, low volatility, high safety, and low toxicity. It is an important chemical raw material widely used in petroleum processing, fine chemicals, pharmaceuticals, pesticides, and electronic products, playing a pivotal role in the chemical industry and being an indispensable raw material for lithium battery manufacturing.

[0003] In the production process of new energy lithium batteries, NMP is used as a solvent to mix the cathode powder. During the coating and drying process, NMP is heated and discharged. Existing NMP recovery technology relies on the water-miscibility of NMP and uses a spray cooling method for recovery. However, during spraying, residue problems can occur due to adhesion.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to solve the problem of low condensate recovery efficiency.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model claims protection for a condensate recovery device, including a box body with a cavity inside, and an air inlet and an air outlet on the surface of the box body. It also includes a condenser pipe, a flow guiding assembly, and a drive assembly. The condenser pipe is disposed inside the cavity, and cooling fluid is disposed inside the condenser pipe cavity. The flow guiding assembly is sleeved on the outer surface of the condenser pipe. The drive assembly is configured to drive the flow guiding assembly to move along the length of the condenser pipe on the surface of the condenser pipe.

[0008] This invention uses a flow guiding component in conjunction with a driving component, which causes the driving component to move the flow guiding component along the length of the condenser tube, scraping off the condensate adhering to the surface of the condenser tube and achieving stable and efficient collection of condensate.

[0009] Preferably, the flow guiding assembly includes a flow guiding ring and a connecting frame. The connecting frame is provided at the output end of the drive assembly, and the connecting frame is perpendicular to the axis of the condenser fitting. The flow guiding ring is arranged on the connecting frame, and the flow guiding ring is sleeved on the outer surface of the condenser fitting, with the inner ring surface of the flow guiding ring contacting and fitting with the outer surface of the condenser fitting.

[0010] The flow guiding assembly consists of two parts: a connecting frame and flow guiding rings. The connecting frame has two functions: first, to provide an installation position for the output end of the drive assembly; second, to install several flow guiding rings so that the output end of the drive assembly can drive several flow guiding rings to move synchronously.

[0011] Preferably, the connecting frame includes wide-side rod units and long-side rod units. Wide-side rod units are arranged parallel to each other on both sides of the condenser pipe fitting. The wide-side rod units are perpendicular to the axis of the condenser pipe fitting. Several rows of long-side rod units are arranged between the two wide-side rod units. The two ends of the long-side rod unit in the middle extend to the outside of the two wide-side rod units to form a connecting part. The connecting part is connected to the output end of the drive assembly. Guide rings are installed on both the long-side rod units and the wide-side rod units.

[0012] The connecting frame consists of two parallel wide-side rod units and several rows of long-side rod units that together form a horizontal support structure. It is worth mentioning that the number of rows of long-side rod units is not fixed and can be adapted to the tortuous arrangement of the actual condenser pipes.

[0013] Preferably, both the wide-side rod unit and the long-side rod unit include several sections of insert rods, and the two ends of the insert rods are respectively connected to the threaded holes opened on the surface of the adjacent guide rings.

[0014] The insertion rod is mainly designed to ensure the disassembly of the connecting frame and the guide ring, so that if any part is damaged, it can still be used by replacement.

[0015] Preferably, the guide ring includes a first annular lobe, a second annular lobe, and a connecting unit. Both the first and second annular lobes are annular in structure. The dividing surfaces of the first and second annular lobes are in contact with each other, and the contact surfaces are detachably installed through the connecting unit. The gaps formed by the contact surfaces and the insertion holes are staggered from each other.

[0016] The guide ring is designed as a separate unit, which is mainly to facilitate the replacement of the guide ring. It is also worth mentioning that the gap formed by the mating surface needs to be staggered from the insertion hole, mainly to avoid the disassembly of the connecting bracket affecting the installation of the guide ring.

[0017] Preferably, the connecting frame further includes a reinforcing rod, with one end of the reinforcing rod connected to the connecting part, and the other end of the reinforcing rod connected to the outermost guide ring of the wide-side rod unit. The gaps formed by the reinforcing rod and the mating surface are staggered from each other.

[0018] The reinforcing rod is similar to a reinforcing rib. The reinforcing rod, the connecting part and the wide side rod unit are enclosed by each other to form a triangular support structure, which makes the entire connecting frame stable and not easily deformed.

[0019] Preferably, the insert rod has a stepped shaft structure, with the diameter of the middle section being larger than the diameters of both ends, and the small-diameter section of the insert rod forming a threaded connection with the threaded hole.

[0020] The special shape of the plug not only ensures a firm connection between the plug and the socket, but also guarantees the overall strength of the plug through the large-diameter section in the middle, ultimately improving the stability of the connector.

[0021] Preferably, the condenser pipes are arranged in a U-shape inside the chamber, with both ends of the condenser pipes extending out of the chamber.

[0022] The condenser pipes extend out of the housing at both ends and are connected to the cold source.

[0023] Preferably, the bolt passes through the mounting hole and engages with the thread of the second annular lobe, and the bolt constitutes a connecting unit.

[0024] By setting bolts, the second annular segment can be separated from or joined to the first annular segment, ensuring the detachability of the guide ring.

[0025] Preferably, a drain pipe is provided on the bottom side of the tank.

[0026] A drain pipe is installed at the bottom of the tank to discharge the condensate to be recovered by utilizing the natural flow of the fluid. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] This utility model claims protection for a condensate recovery device, comprising a housing 1, condenser pipes 2, a flow guiding assembly 3, and a drive assembly 4. The housing 1 has an internal cavity, and through holes on both sides of the housing 1 form an air inlet 10 and an air outlet 11, respectively. A drain pipe 5 is provided on the bottom side of the housing 1. The condenser pipes 2 are U-shaped and installed inside the cavity, with both ends extending out of the housing 1 and connected to a cold source to form a cooling circulation system. The cold source provides cooling fluid to the condenser pipes 2. The flow guiding assembly 3 is fitted onto the outer surface of the condenser pipes 2. The drive assembly 4 is configured to drive the flow guiding assembly 3. The surface of the condenser fitting 2 moves along the length of the tube. The flow guiding assembly 3 includes a flow guiding ring 30 and a connecting frame 31. The connecting frame 31 is provided at the output end of the drive assembly 4. The connecting frame 31 is perpendicular to the axis of the condenser fitting 2. The flow guiding ring 30 is arranged on the connecting frame 31. The flow guiding assembly 3 consists of two parts, namely the connecting frame 31 and the flow guiding ring 30. The connecting frame 31 has two functions: first, to provide an installation position for the output end of the drive assembly 4; second, to install several flow guiding rings 30 so that the output end of the drive assembly 4 can drive several flow guiding rings 30 to move synchronously.

[0038] The connecting frame 31 includes a wide-side rod unit 31a, a reinforcing rod 31c, and a long-side rod unit 31b. The wide-side rod units 31a are arranged parallel to each other on both sides of the condenser pipe fitting 2. The wide-side rod units 31a are perpendicular to each other with the axis of the condenser pipe fitting 2. Several rows of long-side rod units 31b are arranged between the two wide-side rod units 31a. It is worth mentioning that the number of rows of long-side rod units 31b is not fixed and can be adapted to the tortuous arrangement of the actual condenser pipe fitting 2. The long side rod unit 31b located in the middle extends to the outside of the two wide side rod units 31a at both ends to form a connecting part a. The connecting part a is connected to the output end of the drive assembly 4. The connecting part a is connected to one end of the reinforcing rod 31c. The other end of the reinforcing rod 31c is connected to the outermost guide ring 30 of the wide side rod unit 31a. The reinforcing rod 31c and the gap formed by the mating surface are staggered. The reinforcing rod 31c is similar to a reinforcing rib. The reinforcing rod 31c, the connecting part a and the wide side rod unit 31a surround each other to form a triangular support structure, so that the entire connecting frame 31 is stable and not easily deformed.

[0039] Both the long-side rod unit 31b and the wide-side rod unit 31a are equipped with guide rings 30. Both the wide-side rod unit 31a and the long-side rod unit 31b contain several sections of insert rods 310. The insert rods 310 have a stepped shaft structure, with the diameter of the middle section being larger than the diameter of both ends. The small-diameter section of the insert rod 310 forms a threaded connection with the threaded hole. The insert rods 310 are mainly used to ensure the disassembly of the connecting frame 31 and the guide ring 30, so that if any part is damaged, it can still be used by replacement. The flow guide ring 30 is sleeved on the outer surface of the condenser fitting 2, and the inner ring surface of the flow guide ring 30 is in contact with the outer surface of the condenser fitting 2. The flow guide ring 30 includes a first ring lobe 301, a second ring lobe 302 and a connecting unit 303. The first ring lobe 301 and the second ring lobe 302 are both annular structures. The dividing surfaces of the first ring lobe 301 and the second ring lobe 302 are in contact with each other, and the contact surfaces are detachably installed through the connecting unit 303. The gap formed by the contact surfaces is staggered from the insertion hole. The flow guide ring 30 is set in a split type, mainly to facilitate the installation of the flow guide ring 30 on the surface of the condenser fitting 2. It is worth mentioning that the gap formed by the contact surfaces needs to be staggered from the insertion hole, mainly to avoid the disassembly process of the connecting bracket 31 affecting the installation of the flow guide ring 30.

[0040] Based on this, a practical application scenario for the condensate recovery device is provided, specifically the recovery of NMP liquid, where NMP is N-methylpyrrolidone. N-methylpyrrolidone is miscible with water, which is existing technology and will not be described in detail here.

[0041] In practical use, the specific steps are as follows:

[0042] First, the gas containing NMP needs to be processed so that it enters the housing 1 through the air inlet 10.

[0043] Secondly, the cooling fluid is introduced into the condenser tube 2 and exchanges heat with the gas to be treated through the tube wall of the condenser tube 2. NMP in the gas condenses and precipitates and is adsorbed on the tube wall of the condenser tube 2.

[0044] Then, the drive assembly 4 is preferably an electric push rod, which pushes the connecting frame 31 to move. The connecting frame 31 drives the guide ring 30 to push the NMP-containing condensate to the bottom of the condenser fitting 2, which drips onto the bottom of the box 1 and is discharged through the drain pipe 5.

[0045] It is worth mentioning that the guide ring 30 and the connecting frame 31 can also be disassembled. Specifically, the connecting unit 303 is preferably a bolt, and the second ring lobe 302 has an axially penetrating mounting hole leading to the second ring lobe 302. The bolt passes through the mounting hole and engages with the thread of the second ring lobe 302. By unscrewing the bolt, the first ring lobe 301 and the second ring lobe 302 can be separated.

[0046] This invention uses a flow guiding component 3 paired with a driving component 4 to drive the flow guiding component 3 to move along the length of the condenser tube surface, scraping off the condensate adhering to the surface of the condenser tube 2, thus collecting the condensate stably and efficiently.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
