Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically, to a waste gas treatment device for lithium-ion battery electrolyte production. Background Technology

[0002] The electrolyte in a lithium-ion battery is the "blood" of the battery. It is responsible for conducting lithium ions between the positive and negative electrodes and is crucial to the battery's performance. During its production process, especially in steps such as feeding, stirring, mixing, filtering, and filling, industrial waste gas is inevitably generated. To avoid the environmental impact of the waste gas, existing technologies often employ a combined process. First, the waste gas is neutralized and absorbed by an alkaline spray tower, taking advantage of the water-soluble nature of hydrogen fluoride. After removing the hydrogen fluoride, the waste gas then enters a subsequent unit for further treatment of the remaining volatile organic compounds.

[0003] Although a spray tower is installed in the process, if the demisting effect is poor or the operating conditions fluctuate, particulate matter may still remain in the exhaust gas. Dust particles and potentially condensed high-boiling-point organic matter carried in the exhaust gas will clog the micropores of the activated carbon layer, causing the pressure drop of the device to increase sharply, the processing air volume to decrease, and the purification efficiency to decrease, which to some extent reduces the practicality of the device. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a waste gas treatment device for lithium-ion battery electrolyte production, which achieves impurity filtration treatment of waste gas before it enters subsequent treatment equipment, avoids particulate impurities entrained in the waste gas from clogging the activated carbon layer of the subsequent equipment, ensures that the device can operate normally, and guarantees its purification efficiency, thereby solving the problems mentioned in the background art.

[0015] In a preferred embodiment, the system further includes a stagnation ring disposed on the surface of the support column. The inner ring of the stagnation ring has a rough surface structure and is in contact with the outer wall of the side end of the rotating rod.

[0016] In a preferred embodiment, the system further includes a column and a connecting ring.

The inner ring of the connecting ring is in contact with the outer periphery of the extension end of the electric push rod.

[0017] In a preferred embodiment, the outer periphery of the ring is fitted against the inner wall of the air intake pipe, and the inner ring of the ring is configured as an arc surface structure.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention, by setting up a filter plate, filters the exhaust gas after it has been sprayed into the inlet pipe. The filter plate, located in the mounting ring, filters the exhaust gas, blocking residual particulate impurities. When the exhaust gas stops flowing, the blocked particulate impurities fall to the bottom of the inlet pipe through the arc-shaped structure of the ring and are collected in the collection tank. This achieves impurity filtration of the exhaust gas before it enters the subsequent treatment equipment, preventing particulate impurities in the exhaust gas from clogging the activated carbon layer of the subsequent equipment, ensuring the normal operation of the device, guaranteeing its purification efficiency, and thus improving the practicality of the device.

[0020] 2. This invention uses a motor to drive the mounting column to rotate, causing the active roller mounted at one end of the mounting column to rotate synchronously. Under the transmission of the drive belt, the connecting ring in contact with the drive belt also rotates accordingly. During the rotation of the connecting ring, the scraper attached to its surface rotates on the inner wall of the air intake pipe to scrape off particulate impurities adhering to the inner wall of the air intake pipe. Furthermore, the rotation of the connecting ring causes the fixing ring mounted on its right side to rotate synchronously. During the rotation of the fixing ring, the abutment ball contacts the mounting ball, pushing the entire mounting ring. When the spring between the fixed base and the movable plate is compressed and deformed, the mounting ring can return to its original position under the elastic action of the spring when the abutting ball separates from the mounting ball. The continuous reciprocating movement of the mounting ring can realize the vibration of the filter plate, which prevents the blocked impurities from clogging the holes of the filter plate. This achieves the cleaning of impurities attached to the inner wall of the air inlet pipe, prevents impurities from causing the actual flow diameter of the pipe to decrease, and increases airflow resistance, ensuring that the exhaust gas can flow normally. At the same time, the reciprocating movement of the filter plate can also prevent its holes from being blocked, further improving the practicality of the device.

[0021] 3. This invention collects particulate impurities blocked by a collection groove on the top of the packer. Subsequently, an electric push rod at the bottom of the fixed base extends and moves the packer down to separate it from the air intake pipe. The packer can then be deflected around the rotating rod, causing the collection groove to open and tilt, so that the collected particulate matter can be discharged and treated uniformly. This achieves effective collection of particulate impurities and avoids their accumulation in the air intake pipe, which would increase the burden of subsequent cleaning. Attached Figure Description

The outer periphery of the sealing gasket 11 is in contact with the inner wall of the air intake pipe 1. Through the sealing gasket 11, it can seal the contact between the mounting ring 2 and the inner wall of the air intake pipe 1 during the movement of the mounting ring 2, preventing exhaust gas from leaking through the gap.

[0035] In a preferred embodiment, a cleaning component 12 is also included, which is disposed inside the intake pipe 1 and located on the side of the surface of the ring pocket 4 opposite to the mounting ring 2.

[0036] In a preferred embodiment, the cleaning assembly 12 includes a T-shaped post 121, a mounting post 122, a motor 123, a drive roller 124, a transmission belt 125, a support roller 126, a connecting shaft 127, a rotating ring 128, a connecting ring 129, a limiting ring 1210, and a scraper 1211.

Through the limiting ring 1210 and the connecting ring 129 installed on one side of the rotating ring 128, the rotating ring 128 can be supported, allowing it to rotate in the intake pipe 1 under the drive of the transmission belt 125.

[0037] In a preferred embodiment, the system further includes a fixing ring 1212, an abutment ball 1213, and a fitting seat 1214. The fixing ring 1212 is fixedly connected to the side of the rotating ring 128 opposite to the connecting ring 129. The abutment ball 1213 is disposed opposite to both sides of the surface of the fixing ring 1212, and the surface of the abutment ball 1213 is in contact with the surface of the mounting ball 5. The fitting seat 1214 is disposed outside the air intake pipe 1, and the inner wall of the fitting seat 1214 is in contact with the surface of the transmission belt 125. Through the fitting seat 1214, the position where the transmission belt 125 passes through the air intake pipe 1 can be sealed to prevent the gap between the transmission belt 125 and the air intake pipe 1 from increasing after long-term transmission, thus preventing exhaust gas leakage and ensuring that exhaust gas can flow in the air intake pipe 1.

[0038] In a preferred embodiment, a collection component 13 is also included, which is disposed at the bottom of the air intake pipe 1.

[0039] In a preferred embodiment, the collection assembly 13 includes a second fixed seat 131, an electric push rod 132, a base plate 133, a support column 134, a rotating rod 135, a connecting seat 136, a sealing seat 137, a sealing plate 138, and a collection groove 139. The second fixed seat 131 is disposed opposite to each other on both sides of the bottom of the air intake pipe 1. The electric push rod 132 is fixedly installed on the bottom surface of the second fixed seat 131.

[0040] In a preferred embodiment, a retaining ring 1310 is also included. The retaining ring 1310 is disposed on the surface of the support column 134. The inner ring of the retaining ring 1310 is configured with a rough surface structure and fits against the outer wall of the side end of the rotating rod 135. Through the retaining ring 1310, the friction generated by its rough surface structure contacting the rotating rod 135 can keep the sealing seat 137 at a fixed angle, preventing it from rotating accidentally and affecting particulate matter collection or failing to keep flush with the bottom of the air intake pipe 1.

[0041] In a preferred embodiment, the device further includes a column 1311 and a sleeve ring 1312. The top end of the column 1311 is fixedly connected to the bottom surface of the fixed base 131. The sleeve ring 1312 is disposed at the bottom end of the column 1311. The inner ring of the sleeve ring 1312 fits against the outer periphery of the extension end of the electric push rod 132. Through the sleeve ring 1312, the electric push rod 132 can be radially supported after it extends, preventing the spacer seat 137 from applying excessive radial force to the electric push rod 132 after it moves down, thus affecting its normal extension and retraction.

[0042] In a preferred embodiment, the outer periphery of the ring 4 is fitted against the inner wall of the air intake pipe 1, and the inner ring of the ring 4 is configured as an arc surface structure.

[0043] The working principle of this invention is as follows: After the exhaust gas is treated by spraying, it enters the intake pipe 1. The exhaust gas can be filtered by the filter plate 3 set in the mounting ring 2, so that the residual particulate impurities in the exhaust gas are blocked. When the exhaust gas stops flowing, the blocked particulate impurities will fall to the bottom of the intake pipe 1 through the arc surface structure of the ring 4 and enter the collection tank 139 for collection.

[0044] The motor 123 drives the mounting column 122 to rotate, causing the drive roller 124 mounted on one end of the mounting column 122 to rotate synchronously. Under the transmission action of the transmission belt 125, the connecting ring 129 in contact with the transmission belt 125 also rotates accordingly. During the rotation of the connecting ring 129, the scraper 1211 attached to its surface rotates on the inner wall of the air intake pipe 1 to scrape off particulate impurities adhering to the inner wall of the air intake pipe 1. Furthermore, through the rotation of the connecting ring 129, the scraper 1211 mounted on its right side... The fixed ring 1212 rotates synchronously, and during the rotation of the fixed ring 1212, the abutting ball 1213 can contact the mounting ball 5 to push the mounting ring 2 as a whole. At this time, the spring 8 set between the fixed seat 6 and the movable plate 9 is compressed and deformed. When the abutting ball 1213 separates from the mounting ball 5, the mounting ring 2 can be reset and moved under the elastic action of the spring 8. Thus, through the continuous reciprocating movement of the mounting ring 2, the filter plate 3 can be vibrated, that is, the blocked impurities can be prevented from clogging the holes of the filter plate 3.

[0045] The blocked particulate impurities can be collected by the collection groove 139 opened on the top of the packer seat 137. Subsequently, the electric push rod 132 set at the bottom of the fixed seat 131 extends and drives the packer seat 137 to move down as a whole, so that it separates from the air inlet pipe 1. Then the packer seat 137 can be deflected around the rotating rod 135, so that the collection groove 139 is open and tilted, so that the collected particulate matter can be discharged and treated uniformly.

[0046] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
