Detailed Implementation

[0028] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Example 1

[0030] A tail gas treatment device for the production of lithium carbonate from lepidolite, such as Figures 1-11 As shown, the device includes a liquid storage frame 1, a spray frame 2 connected to the top of the liquid storage frame 1, a water pump 4 connected to the right side of the liquid storage frame 1, a water supply pipe 3 connected between the water pump 4 and the spray frame 2, a nozzle 5 connected to the upper end of the water supply pipe 3, the nozzle 5 being located inside the spray frame 2, three mounting heads 6 connected to the top of the liquid storage frame 1 and the bottom of the spray frame 2, a first drain pipe 7 and a second drain pipe 8 snapped between the corresponding mounting heads 6, a spraying mechanism provided on the spray frame 2, the spraying mechanism being used to adjust the water flow state inside the spray frame 2, and a connecting mechanism 10 provided on the mounting head 6, the connecting mechanism 10 being used for quick-release installation of the first drain pipe 7 and the second drain pipe 8.

[0031] It should be noted that first rely on the connection mechanism 10 on the first sewer pipe 7 and the second sewer pipe 8 are quickly installed, in the process of operation, the liquid frame 1 is provided with liquid (such as water or other absorbent) for absorbing and treating harmful substances in tail gas, water pump 4 extracts liquid from the liquid frame 1, and transports it to the spray head 5 located in the liquid spray frame 2 through the water pipe 3, when the liquid reaches the spray head 5, it is uniformly sprayed into the space inside the liquid spray frame 2, with the movement of the tail gas, the tail gas will start to move upward through the first sewer pipe 7 and the second sewer pipe 8, at this time, the liquid flow state in the liquid spray frame 2 is adjusted by the liquid spray mechanism, so that the liquid flows slowly along the inner wall of the first sewer pipe 7 and the second sewer pipe 8, and is in contact with the rising tail gas in the opposite direction, in this process, the harmful components (such as acid gas, heavy metal, etc.) in the tail gas will react chemically or physically with the liquid, so as to be removed, and the purified tail gas continues to rise and is discharged through the discharge port.

[0032] The liquid outlet mechanism 9 comprises a lifting rotating rod 91, the lifting rotating rod 91 is slidably and rotatably connected to the liquid spray frame 2, and the lifting rotating rod 91 is used for adjusting and blocking the water outlet at the lower part of the liquid spray frame 2. The top of the lifting rotating rod 91 is rotatably connected with a mounting plate 92, a hydraulic cylinder 93 is installed on the upper part of the liquid spray frame 2, the extension end of the hydraulic cylinder 93 is connected with the middle part of the mounting plate 92, a driving motor 94 is installed on the mounting plate 92, the output shaft of the driving motor 94 is connected with the lifting rotating rod 91 in the middle part, a synchronous assembly 95 is connected between the lifting rotating rods 91, a limiting seat 96 is installed on the upper side of the front part of the liquid spray frame 2, and the limiting seat 96 is used for limiting and blocking the mounting plate 92.

[0033] It should be noted that the hydraulic cylinder 93 is used as a power source, and its extension end is connected with the middle part of the mounting plate 92. When it is necessary to adjust the water outlet at the lower part of the liquid spray frame 2, the hydraulic cylinder 93 acts, and the position of the mounting plate 92 is lifted or lowered by lengthening or shortening the extension end. Since the top of the lifting rotating rod 91 is rotatably connected with the mounting plate 92, the lifting rotating rod 91 also slides accordingly with the up and down movement of the mounting plate 92. Meanwhile, the driving motor 94 is installed on the mounting plate 92, and its output shaft is connected with the lifting rotating rod 91 in the middle part. When the driving motor 94 starts, it will drive the lifting rotating rod 91 directly connected therewith to rotate, and the synchronous assembly 95 ensures that all the lifting rotating rods 91 can rotate in unison, thereby ensuring the consistency and stability of the whole device. In this way, the rotation of the lifting rotating rod 91 can accurately adjust and block the water outlet at the lower part of the liquid spray frame 2, so as to control the direction and flow of the liquid outflow.

[0034] The connecting mechanism 10 comprises a fixing ring 102, the fixing ring 102 is arranged on each mounting head 6, the spring 103 is connected to the fixing ring 102, the end of the spring 103 is connected to the connecting pipe 101, and the connecting pipe 101 is used for clamping and assembling the first drain pipe 7 and the second drain pipe 8.

[0035] It should be noted that the connecting mechanism 10 is designed for quick installation and disassembly of the first drain pipe 7 and the second drain pipe 8, so as to ensure the convenience of maintenance and cleaning work. Each mounting head 6 is provided with a fixing ring 102, which provides a stable base for the whole connecting mechanism 10. The spring 103 is connected to the fixing ring 102. The design of the spring 103 enables the connecting pipe 101 to have a certain range of motion while providing the necessary elastic restoring force. When it is necessary to install the first drain pipe 7 or the second drain pipe 8 in place, the operator only needs to align one end of the drain pipe with the connecting pipe 101 and apply appropriate pressure. Under the action of pressure, the spring 103 is compressed, so that the connecting pipe 101 can temporarily give way to space to facilitate the smooth insertion of the drain pipe. Once the first drain pipe 7 and the second drain pipe 8 reach the correct position, the spring 103 will restore to its original state, pushing the connecting pipe 101 tightly against the outer wall of the drain pipe to achieve safe and reliable clamping. In this way, not only the good sealing performance is ensured, but also the size variation within a certain range can be adapted due to the presence of the spring 103, thereby increasing the compatibility and stability of the system. When it is necessary to disassemble the drain pipe, the operator can manually press the connecting pipe 101 away from the first drain pipe 7 and the second drain pipe 8. At this time, the spring 103 again plays an auxiliary role to help the connecting pipe 101 quickly reset, preparing for the next connection.

[0036] Example 2

[0037] Further comprising a dehumidification mechanism 11, the dehumidification mechanism 11 comprises a dehumidification chamber 111, the dehumidification chamber 111 is connected to the right side of the liquid spraying frame 2, the cover plate 112 is clamped on the top of the dehumidification chamber 111, the blocking mesh frame 113 is slidably connected to the right part in the dehumidification chamber 111, the blocking mesh frame 113 is used for placing the adsorbed material, and the blocking mesh frame 113 and the dehumidification chamber 111 are in a detachable connection structure.

[0038] It should be noted that when the preliminarily treated tail gas enters the dehumidification chamber 111 from the right side of the liquid injection frame 2, it will first contact the blocking net frame 113 located in the right part of the dehumidification chamber 111, and the blocking net frame 113 is placed with adsorbent materials (such as silica gel, activated carbon or other hygroscopic agents), which have strong water absorption performance and can effectively adsorb the water and other pollutants carried in the tail gas. The blocking net frame 113 and the dehumidification chamber 111 are connected in a sliding manner and are of a detachable structure. The blocking net frame 113 can be easily taken out of the dehumidification chamber 111 when needed, so as to facilitate the regular replacement or regeneration of the adsorbent materials, ensuring the persistence and reliability of the dehumidification effect. At the same time, the detachable connection also facilitates the cleaning and maintenance of the inside of the blocking net frame 113 and the dehumidification chamber 111.

[0039] The lower pressing mechanism 12 includes a fixed seat 122, and the upper side of the rear part of the liquid storage frame 1 is connected with three fixed seats 122. Holes are drilled in the fixed seats 122, and connecting rods 123 are connected thereto. The front sides of the connecting rods 123 are rotatably connected with first connecting pieces 121, and the first connecting pieces 121 are connected with adjacent connecting pipe pieces 101. Three guide rods 124 are connected between the rear part of the liquid storage frame 1 and the liquid injection frame 2, and lifting frames 125 are slidably connected to the guide rods 124. The bottom parts of the lifting frames 125 are rotatably connected with adjacent connecting rods 123, and connecting frames 127 are connected to the upper parts and front sides of the lifting frames 125. Second connecting pieces 126 are connected to the front sides of the connecting frames 127, and the second connecting pieces 126 are connected with adjacent connecting pipe pieces 101.

[0040] It should be noted that the upper side of the rear part of the liquid storage frame 1 is connected with three fixed seats 122, and holes are drilled in each fixed seat 122 and connected with connecting rods 123. These connecting rods 123 are responsible for force transmission. The front sides of the connecting rods 123 are rotatably connected with first connecting pieces 121, and the first connecting pieces 121 are connected with adjacent connecting pipe pieces 101, ensuring that when the connecting rods 123 move, the adjacent connecting pipe pieces 101 can be driven to move synchronously through the first connecting pieces 121. During operation, the operator directly presses the lower connecting pipe pieces 101, and at this time, the force acts on the adjacent connecting rods 123, causing the connecting rods 123 to rotate. With the rotation of the connecting rods 123, the lifting frames 125 will slide down along the guide rods 124. With the descent of the lifting frames 125, they will act on the upper connecting pipe pieces 101 again through the connecting frames 127 and the second connecting pieces 126, further ensuring the consistency of the movement of all connecting pipe pieces 101, and then quickly disassembling the first and second drain pipes 7 and 8, thereby improving the disassembly efficiency.
