Description

Technical Field

[0001] This utility model relates to the field of adsorption lithium extraction equipment technology, and in particular to an adsorbent washing and regeneration device with ultrasonic assistance. Background Technology

[0002] Lithium extraction from salt lakes refers to a series of processes and methods for extracting lithium ore from salt lakes. This involves extracting potassium salts from salt lake brine to form lithium-containing brine, and then removing impurities to obtain lithium products such as lithium carbonate.

[0003] In document publication number CN213221206U, a raw brine feeding mechanism 1b is used to transport a mixture of adsorbent and brine to filter cloth 1a. The brine and adsorbent are separated by vacuum. The adsorbent is adsorbed on filter cloth 1a and continuously passes through the brine washing and effluent mechanism 2, the desorption and effluent mechanism 1c, and the brine washing liquid recovery mechanism 3 as the filter cloth 1a is moved.

[0004] When separating the brine from the adsorbent, the separated adsorbent will clog the adsorption sites on the filter cloth, thus prolonging the salt washing time and requiring more rinsing water. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the separated adsorbent clogging the adsorption sites on the filter cloth, thus prolonging the salt washing time, and requiring a large amount of rinsing water during rinsing. Therefore, this invention proposes an adsorbent washing and regeneration device with ultrasonic assistance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design an ultrasonic-assisted adsorbent washing and regeneration device, including a belt vacuum filter with a filter cloth on it. A fixed base is fixedly connected to the belt vacuum filter, and a connecting rod is fixedly connected to the fixed base. One end of the connecting rod is fixedly connected to an open box, which is located above the filter cloth. A lifting mechanism is connected inside the open box, and an ultrasonic transducer is connected to the lifting mechanism. A magnetic support mesh plate mechanism is connected inside the open box, and the magnetic support mesh plate mechanism is located below the ultrasonic transducer.

[0007] Preferably, the lifting mechanism includes a movable frame, which is slidably connected to the open box. An ultrasonic transducer is connected to the movable frame, and an installation plate is fixedly connected to the open box. A threaded rod that drives the movable frame to move in the vertical direction is rotatably connected to the installation plate.

[0008] Preferably, a handle is fixedly connected to the upper end of the threaded rod.

[0009] Preferably, the ultrasonic transducers are provided in a plurality of units and are distributed at equal intervals along the length of the open box.

[0010] Preferably, the magnetic bearing mesh plate mechanism includes a mounting groove extending to the bottom of the open box. A magnetic mesh plate is slidably connected to the mounting groove. Grooves are provided on opposite sides of the mounting groove. A spring is connected to each groove. A limit block is slidably connected to each groove. One end of each spring is fixedly connected to a corresponding limit block. Each limit block is in contact with the bottom end of the magnetic mesh plate.

[0011] Preferably, the open box is connected to a scraping cleaning structure for cleaning the magnetic mesh plate. The scraping cleaning structure includes a movable plate, which is slidably connected to the open box. A scraper is fixedly connected to the bottom end of the movable plate. The scraper contacts the upper sides of the magnetic mesh plate. A motor is fixedly connected to the open box, and a reciprocating screw for driving the movable plate to move is fixedly connected to the output end of the motor.

[0012] The present invention provides an adsorbent washing and salt regeneration device with ultrasonic assistance, which has the following advantages: After the ultrasonic transducer is activated, its vibration effectively accelerates the mass transfer rate of impurities and salts in the internal pores of the adsorbent, which helps to remove the salt and improves the desalination efficiency. The liquid after ultrasonic treatment comes into contact with the magnetic support mesh plate mechanism. The magnetic support mesh plate mechanism fixes the adsorbent with permanent magnets, ensuring that the adsorbent is not easily lost during the treatment process, which improves the salt washing efficiency, reduces water consumption, and solves the problem of crystal blockage of adsorption sites, thus reducing the salt washing time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1: Refer to Figure 1-3 An ultrasonic-assisted adsorbent washing and regeneration device includes a belt vacuum filter 1, a filter cloth 2 on the belt vacuum filter 1, a fixed base 5 fixedly connected to the belt vacuum filter 1, a connecting rod 6 fixedly connected to the fixed base 5, an open box 7 fixedly connected to one end of the connecting rod 6, the open box 7 being located above the filter cloth 2, a lifting mechanism 8 connected inside the open box 7, an ultrasonic transducer 9 connected to the lifting mechanism 8, several ultrasonic transducers 9 being provided and evenly distributed along the length of the open box 7, and a magnetic bearing mesh plate mechanism 10 connected inside the open box 7, the magnetic bearing mesh plate mechanism 10 being located below the ultrasonic transducers 9.

[0017] Work process: The feed pipe 3 introduces the mixture of adsorbent and brine into the open box 7. After the ultrasonic transducer 9 is started, the vibration of the ultrasonic transducer 9 effectively accelerates the mass transfer rate of impurity salt in the internal channels of the adsorbent, which is conducive to removing salt, improving desalination efficiency, and reducing physical damage during the regeneration process of the adsorbent. The liquid after ultrasonic treatment comes into contact with the magnetic support mesh plate mechanism 10. The magnetic support mesh plate mechanism 10 fixes the adsorbent with permanent magnets to ensure that the adsorbent is not easily lost during the treatment process. At the same time, it promotes the initial separation of brine and adsorbent, improves the salt washing efficiency, reduces water consumption, solves the problem of crystal blockage of adsorption sites, reduces the salt washing time, and simultaneously reduces the mechanical wear and loss of the adsorbent. After treatment, the adsorbent and brine fall onto the filter cloth 2. The brine and adsorbent are separated by vacuum. The adsorbent is adsorbed onto the filter cloth 2 and is then washed below the rinsing pipe 4 as the filter cloth 2 is moved along with it.

[0018] Example 2: The distance between the ultrasonic transducer 9 and the magnetic bearing mesh plate mechanism 10 cannot be adjusted. (Refer to...) Figure 3-4As another preferred embodiment of this utility model, the difference from embodiment 1 is that the lifting mechanism 8 includes a movable frame 81, the movable frame 81 is slidably connected to the open box 7, an ultrasonic transducer 9 is connected to the movable frame 81, an installation plate 82 is fixedly connected to the open box 7, a threaded rod 83 that drives the movable frame 81 to move in the vertical direction is rotatably connected to the installation plate 82, and a handle 84 is fixedly connected to the upper end of the threaded rod 83. Rotate handle 84, which drives threaded rod 83 to rotate. After the threaded rod 83 rotates, it drives movable frame 81 to move. Movable frame 81 drives ultrasonic transducer 9 to move in the vertical direction, adjusting the distance between ultrasonic transducer 9 and magnetic bearing mesh plate mechanism 10.

[0019] Example 3: When the magnetic bearing mesh plate mechanism 10 is damaged, it is not easy to replace. Refer to Figure 5 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the magnetic bearing mesh plate mechanism 10 includes a mounting groove 101, which extends to the bottom of the open box 7. A magnetic mesh plate 102 is slidably connected to the mounting groove 101. Grooves 104 are provided on both sides of the mounting groove 101. A spring 103 is connected in each groove 104. A limit block 105 is slidably connected in each groove 104. One end of each spring 103 is fixedly connected to a corresponding limit block 105. Each limit block 105 is in contact with the bottom of the magnetic mesh plate 102. When in use, the limiting block 105 extends out of the groove 104 and supports and limits the magnetic mesh plate 102. When replacing the magnetic mesh plate 102, the limiting block 105 is pushed and retracted into the groove 104, and the limiting block 105 and the magnetic mesh plate 102 are misaligned, so that the magnetic mesh plate 102 can be taken out for easy replacement.

[0020] Example 4: After the magnetic mesh plate 102 is fixed with the adsorbent by the permanent magnet, a lot of debris adheres to the upper sides of the magnetic mesh plate 102, making it inconvenient to clean the magnetic mesh plate 102. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the open box 7 is connected to a scraping cleaning structure 11 for cleaning the magnetic mesh plate 102. The scraping cleaning structure 11 includes a movable plate 111, which is slidably connected to the open box 7. A scraper 112 is fixedly connected to the bottom end of the movable plate 111. The scraper 112 contacts the upper two sides of the magnetic mesh plate 102. A motor 113 is fixedly connected to the open box 7. A reciprocating screw 114 for driving the movable plate 111 to move is fixedly connected to the output end of the motor 113. When cleaning the magnetic mesh plate 102, the motor 113 is powered on and starts to drive the reciprocating screw 114 to rotate. After the reciprocating screw 114 rotates, the movable plate 111 moves back and forth. The movable plate 111 drives the scraper 112 to move back and forth. During the reciprocating movement of the scraper 112, the upper end of the magnetic mesh plate 102 is cleaned.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
