Description

Technical Field

[0001] This utility model relates to a humidification and drying device. Background Technology

[0002] In the lithium battery manufacturing industry, pre-slitting and rolling in the front-end production workshop refers to the process of pressing rolled raw materials through a series of rollers and then slitting them during or after pressing. It combines rolling and slitting technologies to achieve efficient and high-precision processing of rolled materials. However, using traditional processes to produce new formulation materials has two drawbacks: firstly, the thickness tolerance of the electrode sheets after rolling does not meet the ideal effect; secondly, the electrode sheets slightly curl after being laid out. After a series of experiments and tests, a solution was finally found: using high-temperature mist to wet the electrode sheet surface before rolling, followed by rolling, and then drying the electrode sheets after rolling to improve their performance. However, there is currently no equipment that can achieve high-temperature mist wetting of the electrode sheet surface followed by drying after rolling. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] like Figure 1-8As shown, this utility model is implemented using the following scheme: A humidification and drying device includes an electrode humidification mechanism 1 set at the input end of the roller pressing production line and an electrode drying mechanism 2 set at the output end of the roller pressing production line. The roller pressing production line can be an existing roller pressing pre-slitting machine 3. An existing electrode roll placement rack 4 can be set on the front side of the electrode humidification mechanism. The electrode roll 5 is rotatably connected to the electrode roll placement rack through a mandrel, which facilitates the subsequent extraction of the roll. The electrode humidification mechanism includes an atomizer mechanism 6 and a preheating humidification mechanism 7. The output end of the atomizer mechanism is connected to the mist inlet end of the preheating humidification mechanism through a pipeline. The electrode roll is output sequentially through the humidification mechanism, the roller pressing production line, and the electrode drying mechanism. Therefore, the input electrode roll can be preheated and moistened with high-temperature mist by the electrode humidification mechanism before the electrode roll is rolled. Then, the electrode roll is sent into the roller pressing production line. After rolling, it is quickly dried by the electrode drying mechanism and finally output to the next process, solving the problem of defects in the new formula material.

[0028] In this embodiment, the specific structure of the preheating and humidifying mechanism is as follows: the preheating and humidifying mechanism includes a positioning bracket 8, a preheating mechanism 9 is installed on the positioning bracket, and an atomizing humidifying mechanism 10 is installed on the positioning bracket above the preheating mechanism. The input ends of the preheating mechanism and the atomizing humidifying mechanism are both at the bottom, and the output ends are both at the top. The input end of the atomizing humidifying mechanism corresponds to the output end of the preheating mechanism. A guide roller 11 is rotatably connected to the positioning bracket at the input end of the preheating mechanism and the output end of the atomizing humidifying mechanism, which facilitates the feeding of the electrode roll into the preheating mechanism and the transfer of the roll between the output end of the atomizing humidifying mechanism and the input end of the roll forming production line. The output end of the atomizer mechanism is connected to the mist inlet end of the atomizing humidifying mechanism via a pipeline. The electrode roll is input into the roll forming production line via the preheating mechanism.

[0029] In this embodiment, to achieve preheating, the specific preheating mechanism structure is as follows: the preheating mechanism includes a preheating box 12, which contains a preheating cavity. The top and bottom of the preheating box have electrode roll preheating openings 13 communicating with the preheating cavity. Vertical existing heating plates 14 are symmetrically arranged front and back within the preheating cavity. The heating plates are electrically connected to an external power source. A preheating channel is formed between the two heating plates and the upper and lower electrode roll preheating openings, which can rapidly heat both sides of the electrode to approximately 120 degrees Celsius, preparing for the next step of electrode atomization and humidification. More specifically, the preheating box can be composed of two preheating half-boxes, which are fixed together by an existing fastening structure. The two heating plates can be fixed to the front and rear preheating half-boxes respectively, as long as the connection can be achieved using existing bolts. The electrode roll preheating port can be directly opened on the top and bottom edges of one of the preheating half-boxes, or the top and bottom edges of the two preheating half-boxes can be respectively provided with half electrode roll preheating ports. When the two preheating half-boxes are fastened together to form a preheating box, the two corresponding half electrode roll preheating ports combine to form an electrode roll preheating port. The electrode roll enters the preheating channel through the lower electrode roll preheating port of the preheating box, and then exits through the upper electrode roll preheating port and enters the atomization and humidification mechanism. A temperature sensor can be installed in the preheating box for easy temperature monitoring.

[0030] In this embodiment, the atomizing humidification mechanism includes an atomizing humidification box 15, an atomizing chamber 16 inside the atomizing humidification box, and electrode roll humidification openings 17 at the top and bottom of the atomizing humidification box that communicate with the atomizing chamber. A spray tube assembly 18 is symmetrically arranged front and back inside the atomizing chamber. Each spray tube assembly includes at least one horizontal spray tube 19 spaced apart from top to bottom; there can be one or more. This device uses one spray tube assembly containing two horizontal spray tubes, one upper and one lower. A mist-passing elongated hole 20 is formed on the wall of each spray tube along its length, facing the center of the atomizing chamber. Atomization is formed between the two spray tube assemblies and the upper and lower electrode roll humidification openings. The channel, namely the elongated misting holes on the horizontal spray pipes of the two spray pipe groups, faces into the atomization channel, allowing the roll material to be moistened with high-temperature mist on both the front and back sides as it passes through the atomization channel. The two ends of the spray pipes in the same spray pipe group pass through the atomization humidification box and are connected to the atomizer mechanism via parallel pipe 21, so that the high-temperature mist generated by the atomizer mechanism can be passed through the pipes to the horizontal spray pipes and finally sprayed out through the elongated misting holes. The atomization humidification box can be composed of two atomization humidification box halves. The connection method between the two atomization humidification box halves is the same as the connection method between the two preheating half boxes. The opening method of the electrode roll material humidification port is also the same as the opening method of the electrode roll material preheating port, so it will not be described in detail.

[0031] In this embodiment, in order to achieve the return of water droplets after the condensation of the warm mist, at least one downward groove 22 is provided at the bottom of the atomizing humidification box corresponding to the spray tube assembly. An atomizing return hole 23 is provided in the middle of the groove. The atomizing return hole is connected to the atomizer mechanism through the return pipe 24, so that the water droplets after the mist condenses will fall into the groove and finally return to the atomizer mechanism. At the same time, an inclined guide plate can be provided on the humidification opening of the electrode roll to assist the condensed water in falling into the groove.

[0032] In this embodiment, to generate mist, the atomizer mechanism includes an atomizing housing 25, an atomizing water tank 26 located beside the atomizing housing, an atomizing pool 27 installed inside the atomizing housing, and an atomizing plate 28 installed inside the atomizing pool. The atomizing plate is an existing atomizing device, so it will not be described in detail. A water inlet 29 is located on the upper part of the atomizing housing corresponding to the atomizing pool. The water inlet is connected to the atomizing water tank via a pipe with a water pump. A mist outlet 30 is located on the upper part of the atomizing housing corresponding to the atomizing pool. A mist outlet pipe 31 is connected to the mist outlet, and an existing mist heater 32 is connected to the output end of the mist outlet pipe for mist heating. The output end of the device is connected to two spray pipe groups via two parallel pipes. The mist heater heats the mist, and when the temperature reaches 80 degrees, the mist is delivered. An air inlet is provided on the lower side of the atomizing machine box. An air intake fan 34 is installed on the air inlet inside the atomizing machine box. The atomizing return hole is connected to the atomizing water tank via a return pipe. In use, water from the atomizing water tank is drawn by a water pump and falls into the atomizing pool through the water inlet. The atomizing plate starts to work, and mist is generated. Then the air intake fan starts to work and blows air into the atomizing machine box. The mist flows to the mist outlet under the action of the air intake fan and is sent to the horizontal spray pipe by the mist outlet pipe, realizing the generation and delivery of mist.

[0033] In this embodiment, for the sake of reasonable design, a low liquid level sensor 35 is provided on the top of the atomizing plate to detect whether the liquid level of the atomizing pool meets the minimum height of the atomizing plate. An overflow hole is provided on the upper part of the side wall of the atomizing pool. The overflow hole is connected to the atomizing water pool through an overflow pipe 36 to avoid the water pump delivering too much water, causing water to overflow directly from the top of the atomizing pool and fall into the atomizing machine box.

[0034] In this embodiment, to achieve electrode drying, the electrode drying mechanism includes a sliding trolley 37, on which a drying chamber 38 is rotatably connected. The drying chamber contains a drying cavity, and the top and bottom of the drying chamber have electrode roll drying openings 39 that communicate with the drying cavity. Vertical graphene heating plates 40 are symmetrically arranged front and back within the drying cavity to dry both sides of the rolled electrode. A drying channel is formed between the two graphene heating plates and the two electrode roll drying openings. The drying chamber consists of two... The unit consists of two drying half-chambers, which are hinged on one side and snap-fitted on the other side. The snap-fit ​​is achieved using existing buckles or threaded connections, as long as one side is detachable and the other is hinged. The graphene heating plate can be set in the two drying half-chambers. Because one side is detachable and the other is hinged, the drying chamber can be opened quickly and the belt can be threaded. The opening method of the electrode roll drying port is the same as that of the electrode roll preheating port, so it will not be described in detail.

[0035] In this embodiment, for rational design, the sliding trolley includes a sliding base 41, with four wheels 42 mounted on the four corners of the sliding base. A drying mechanism mounting frame 44 is mounted on the sliding base. The drying box is rotatably connected to the drying mechanism mounting frame. One side of the drying half-box can be equipped with a rotating shaft, and the drying mechanism mounting frame is equipped with a rotating seat corresponding to the rotating shaft. The rotating shaft is locked in the rotating seat by bolts, realizing the rotation and fixation of the drying box. The edge drying box can be rotated and adjusted according to the position of the output end of the roller pre-slitting machine. Of course, the drying mechanism mounting frame can be equipped with an existing control box 43 for controlling the heating temperature of the graphene heating plate. The electrode drying mechanism can remove the moisture left on the surface of the electrode in the previous process, avoiding the impact of the added humidification process on other subsequent processes, thus completing the workflow of the entire humidification and drying device. This provides an effective solution to the defect problem after the roller pre-slitting process of the new formula material.
