Description

Technical Field

[0001] This utility model relates to the field of lithium ore production technology, specifically to a lithium ore extraction and preparation device. Background Technology

[0002] Currently, in the process of lithium ore extraction and preparation, a roasting furnace is often used for high-temperature calcination. During the roasting process, a large amount of flue gas is generated. In order to avoid the harm of particulate matter in the flue gas to the surrounding environment, a filter screen is usually fixed on the flue gas exhaust pipe of the roasting furnace with screws to filter the particulate matter in the flue gas. However, screws are prone to rust when exposed to air for a long time, which makes it difficult to disassemble the filter screen. After the filter screen has been used for a long time, the filtration effect will deteriorate, resulting in a decrease in the filtration effect of the flue gas. To address this issue, we propose a lithium ore extraction and preparation device to solve the problems mentioned in the background technology. Utility Model Content

[0003] The purpose of this invention is to provide a lithium ore extraction and preparation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a lithium ore extraction and preparation device, comprising a roasting furnace body, wherein a flue pipe is fixedly connected to the top of the roasting furnace body and communicates with it, a flue gas filter assembly is inserted into the opening at the top of the flue pipe, a limiting sleeve is fixedly connected to the outer surface of the flue pipe, and a locking assembly for fixing the flue gas filter assembly is rotatably connected inside the limiting sleeve.

[0005] The flue gas filtration assembly includes a filter frame, four positioning brackets are equidistantly mounted around the outer surface of the filter frame, the side of the positioning brackets is provided with a locking socket, and the filter body is mounted on the filter frame.

[0006] The locking assembly includes a rotating ring, which is rotatably connected to the inner side of the limiting shell through a limiting ring on its outer side. Four connecting seats are equidistantly mounted around the top of the rotating ring, and a locking bracket adapted to the locking socket is fixedly connected to the end of the connecting seat away from the rotating ring.

[0007] Furthermore, a screw sleeve is fixedly connected to the center position of the bottom of the filter frame, a connecting rod is connected to the internal thread of the screw sleeve, an annular frame is fixedly connected to the bottom end of the connecting rod, and a scraper is fixedly connected to the outer surface of the annular frame.

[0008] Furthermore, the upper surface of the locking bracket is provided with anti-slip texture.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention utilizes a roasting furnace to achieve high-temperature roasting of lithium ore. The flue gas generated during production is discharged through an exhaust pipe, and the filter body inside the filter frame filters the flue gas particles. When the filter body needs replacement, the rotating ring can be rotated under the limit of the limiting ring, which in turn drives the connecting seat and locking bracket to rotate. This causes the locking bracket to disengage from the locking socket on the positioning bracket, allowing the filter frame to be pulled out. During the pulling process, the ring frame can be moved upwards through the connection of the screw sleeve and connecting rod. The scraper on its outer side can scrape off impurities adhering to the exhaust pipe, reducing the cleaning workload for workers. This lithium ore extraction and preparation device has a reasonable structural design and is easy to use. During high-temperature roasting of lithium ore, particles can be filtered through the filter assembly at the top of the exhaust pipe. The filter is installed using a snap-fit ​​method, allowing for quick removal and replacement when dirty, thus avoiding filtration effects affected by impurities clogging the filter. It has high practicality. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4A lithium ore extraction and preparation device includes a roasting furnace body 1. Support legs are installed at the four corners of the bottom of the roasting furnace body 1 to improve its stability during operation. A furnace door is hinged to the front side to allow for the insertion and removal of lithium ore. Its heating method and other working principles are mature existing technologies and will not be described again. A flue pipe 2 is fixedly connected to the top of the roasting furnace body 1 and communicates with it. The flue pipe 2 can discharge the flue gas generated during the roasting process. A flue gas filter assembly 3 is inserted into the opening at the top of the flue pipe 2. The flue gas filter assembly 3 can filter particulate impurities in the discharged gas. A limiting sleeve 4 is fixedly connected to the outer surface of the flue pipe 2. A locking assembly 5 for fixing the flue gas filter assembly 3 is rotatably connected inside the limiting sleeve 4.

[0018] The flue gas filter assembly 3 includes a filter frame 31. Four positioning brackets 32 are equidistantly mounted around the outer surface of the filter frame 31. Four slots that are compatible with the positioning brackets 32 are equidistantly mounted around the top of the exhaust pipe 2, which can form a preliminary fixation of the filter frame 31. Locking sockets 33 are provided on the side of the positioning brackets 32. The filter body 34 is mounted on the filter frame 31.

[0019] The locking assembly 5 includes a rotating ring 51, which is rotatably connected to the inner side of the limiting sleeve 4 via a limiting ring 52 on its outer side. The limiting ring 52 can prevent the rotating ring 51 from moving vertically. Four connecting seats 53 are equidistantly mounted around the top of the rotating ring 51. A locking bracket 54 adapted to the locking socket 33 is fixedly connected to the end of the connecting seat 53 away from the rotating ring 51. The upper surface of the locking bracket 54 is provided with anti-slip texture. By setting the anti-slip texture, the friction between the locking bracket 54 and the locking socket 33 can be increased, and the natural rotation of the rotating ring 51, connecting seats 53 and locking bracket 54 caused by vibration during equipment operation can be avoided.

[0020] A threaded sleeve 35 is fixedly connected to the center of the bottom of the filter frame 31. A connecting rod 36 is connected to the internal thread of the threaded sleeve 35. An annular frame 37 is fixedly connected to the bottom end of the connecting rod 36. A scraper 38 is fixedly connected to the outer surface of the annular frame 37. When the filter frame 31 is pulled out, the annular frame 37 can be moved upward through the connection of the threaded sleeve 35 and the connecting rod 36. The scraper 38 on its outer side can scrape off the impurities adhering to the exhaust pipe 2, thereby reducing the cleaning workload of the workers. The connecting rod 36 and the threaded sleeve 35 adopt a detachable design, which can be removed when the filter frame 31 and the filter body 34 are replaced, without having to replace them together.

[0021] This lithium ore extraction and preparation device has a reasonable structural design and is easy to use. During the high-temperature roasting of lithium ore, particles can be filtered through the filter screen assembly at the top of the flue gas pipe. The filter screen is installed by snap-fit, and can be quickly removed and replaced when it is dirty, thus avoiding the filtration effect affected by impurities. It has high practicality.

[0022] In use, the high-temperature roasting of lithium ore is achieved using the roasting furnace body 1. The flue gas generated during the production process is discharged through the exhaust pipe 2, and the filter body 34 inside the filter frame 31 filters the flue gas particles. When the filter body 34 needs to be replaced, the rotating ring 51 can be rotated under the limit of the limiting ring 52, which in turn drives the connecting seat 53 and the locking bracket 54 to rotate, so that the locking bracket 54 disengages from the locking socket 33 on the positioning bracket 32, and the filter frame 31 can be pulled out. During the pulling process, the ring frame 37 can be moved upward through the connection of the screw sleeve 35 and the connecting rod 36. The scraper 38 on its outer side can scrape off the impurities adhering to the exhaust pipe 2, thereby reducing the cleaning workload of workers.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
