Technical Field
[0001] This utility model belongs to the field of crystallization mother liquor recovery technology, specifically relating to a high-efficiency crystallization mother liquor recovery device. Background Technology
[0002] The solubility of a substance varies with conditions such as temperature and solvent composition. When a solution reaches a supersaturated state, the solute will precipitate in crystal form, while impurities remain in the solution due to unsaturation or different solubilities, thus achieving separation. By rationally selecting crystallization methods and optimizing process conditions, crystallization extraction can efficiently achieve the separation and purification of substances, and is widely used in industrial production and laboratory research.
[0003] Currently, most existing crystal extraction methods typically involve crystallization and precipitation in a vat, followed by separation of the crystals using a centrifuge. However, the mother liquor separated in traditional crystallization extraction methods is often difficult to recover, resulting in waste. Furthermore, if not properly handled, it can easily pollute the environment and pose safety hazards. Some mother liquor recovery devices have appeared on the market, but their recovery efficiency is relatively low. Utility Model Content
[0004] The purpose of this invention is to provide a high-efficiency crystallization mother liquor recovery device, which aims to solve the problem that in the existing technology, most crystals are extracted by crystallizing and settling in a vat and then separating the crystals in a centrifuge. However, the mother liquor separated in the traditional crystallization extraction method is often difficult to recover, which leads to waste and, if not properly treated, can easily pollute the environment and create safety hazards. Some mother liquor recovery devices have appeared on the market, but their recovery efficiency is relatively low.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency crystallization mother liquor recovery device, comprising a lower box, an upper box installed on the top of the lower box, a box cover hinged to the top of the upper box, and a connecting plate fixedly connected to the bottom inner side of the upper box;
[0006] A motor is installed at the bottom of the connecting plate, and a filter frame is connected to the output end of the motor. A filter element is installed on the inner side of the filter frame. A guide rail is fixedly connected to the inner wall of the upper box. Two liquid guide plates are symmetrically distributed on the inner wall of the lower box. A collection box is inserted through the surface of the lower box, and rollers are installed at the four corners of the bottom of the collection box.
[0007] As a preferred embodiment of the efficient crystallization mother liquor recovery device of this utility model, the connecting plate has notches at its four corners, and the lower box and the upper box are connected through the notches at the four corners of the connecting plate.
[0008] In a preferred embodiment of this utility model of a high-efficiency crystallization mother liquor recovery device, the collection box is located at the bottom of symmetrically distributed liquid guiding plates.
[0009] As a preferred embodiment of the efficient crystallization mother liquor recovery device of this utility model, the filter frame can be rotatably connected to the upper box through a guide rail.
[0010] As a preferred embodiment of the efficient crystallization mother liquor recovery device of this utility model, two fixing blocks are symmetrically distributed on the two outer walls of the upper box, and a limit slot is opened at one end of the two fixing blocks. Mounting seats are fixedly connected to the two outer walls of the lower box, and springs are provided inside the mounting seats. A movable block is connected to the end of the spring, and an L-shaped locking block is fixedly connected to the top of the movable block.
[0011] As a preferred embodiment of the efficient crystallization mother liquor recovery device of this utility model, the lower box can form an elastic locking structure with the upper box through a fixed block, a limiting slot, a mounting seat, a spring, a movable block, and an L-shaped locking block.
[0012] As a preferred embodiment of the efficient crystallization mother liquor recovery device of this utility model, the end of the L-shaped card block away from the movable block is adapted to the size of the limiting card slot.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By pouring the crystallization mother liquor into the filter frame and closing the lid, the filter frame is rotated by a motor. The centrifugal force of the rotating filter frame, in conjunction with the inner filter element, achieves filtration and separation of the crystallization mother liquor. The separated liquid, thrown out by centrifugal force, flows into the lower chamber through the notches at the four corners of the connecting plate. The separated liquid is then guided to the collection box by symmetrically distributed liquid guide plates in the lower chamber. Finally, the collection box can be removed from the lower chamber by pulling the handle. Thus, the above structure enables efficient filtration and recovery of the crystallization mother liquor.
[0015] By moving the movable block with the lever, the L-shaped locking block moves. At this time, one end of the L-shaped locking block will disengage from the limiting slot at one end of the fixed block. Then, by lifting the upper box, the bottom of the upper box can be removed from the lower box, thus facilitating the separation of the lower and upper boxes. Separating the lower and upper boxes makes it easier for staff to clean the inside of the device. Attached Figure Description

[0022] 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.
[0023] Please see Figures 1-4 The present invention provides the following technical solution: a high-efficiency crystallization mother liquor recovery device, including a lower box 1, an upper box 2 installed on the top of the lower box 1, a box cover 3 hinged to the top of the upper box 2, and a connecting plate 4 fixedly connected to the bottom inner side of the upper box 2.
[0024] A motor 5 is installed at the bottom of the connecting plate 4. A filter frame 6 is connected to the output end of the motor 5. A filter element 7 is installed on the inner side of the filter frame 6. A guide rail 8 is fixedly connected to the inner wall of the upper box 2. Two liquid guide plates 9 are symmetrically distributed on the inner wall of the lower box 1. A collection box 10 is inserted through the surface of the lower box 1. Rollers 11 are installed at the four corners of the bottom of the collection box 10.
[0025] Preferably, the connecting plate 4 has notches at its four corners, and the lower box 1 and the upper box 2 are connected by the notches at the four corners of the connecting plate 4. The collection box 10 is located at the bottom of the symmetrically distributed liquid guide plates 9, and the filter frame 6 can form a rotating connection structure with the upper box 2 through the guide rail 8.
[0026] In practical use, the mother liquor is poured into the filter frame 6 and the box cover 3 is closed. At this time, the motor 5 drives the filter frame 6 to rotate. The centrifugal force of the rotating filter frame 6, together with the inner filter element 7, achieves the filtration and separation of the mother liquor. The separated liquid thrown out by the centrifugal force flows into the lower box 1 through the notches at the four corners of the connecting plate 4. At this time, the separated liquid is guided to the collection box 10 by the liquid guide plates 9 symmetrically distributed in the lower box 1. Finally, the collection box 10 can be pulled out from the lower box 1 by pulling the handle. Thus, the above structure can achieve efficient filtration and recovery of the mother liquor.
[0027] It should be noted that the motor 5 has an external power supply and is connected to the control switch. The two symmetrically distributed liquid guide plates 9 are set at an angle of 35 degrees. The bottom of the upper box 2 is embedded in the top of the lower box 1. By adopting an insertion installation, leakage of the crystallizing mother liquor flowing downwards can be avoided.
[0028] Preferably, two fixing blocks 12 are symmetrically distributed on the outer walls of both sides of the upper housing 2. One end of each fixing block 12 is provided with a limiting groove 13. The outer walls of both sides of the lower housing 1 are fixedly connected with mounting bases 14. A spring 15 is provided inside the mounting base 14. A movable block 16 is connected to the end of the spring 15. An L-shaped locking block 17 is fixedly connected to the top of the movable block 16. The lower housing 1 can form an elastic locking structure with the upper housing 2 through the fixing blocks 12, limiting grooves 13, mounting bases 14, springs 15, movable blocks 16, and L-shaped locking blocks 17. The end of the L-shaped locking block 17 away from the movable block 16 is adapted to the size of the limiting groove 13.
[0029] In practical use, the movable block 16 is moved by the lever to drive the L-shaped locking block 17 to move. At this time, one end of the L-shaped locking block 17 will disengage from the limiting slot 13 at one end of the fixed block 12. Then, by lifting the upper box 2, the bottom of the upper box 2 can be removed from the lower box 1, thereby making it easy to separate the lower box 1 and the upper box 2. By separating the lower box 1 and the upper box 2, it is convenient for the staff to clean the inside of the device.
[0030] Conversely, during assembly, the movable block 16 is moved by the lever to move the L-shaped locking block 17, and then the bottom of the upper box 2 is inserted into the inner side of the lower box 1. At this time, by releasing the lever, the L-shaped locking block 17 will pop out under the action of the spring 15, so that one end of the L-shaped locking block 17 is inserted into the limiting slot 13 at the end of the fixing block 12, thereby achieving fixation.
[0031] Working principle: First, pour the crystallization mother liquor into the filter frame 6 and then close the cover 3. At this time, the motor 5 drives the filter frame 6 to rotate. The centrifugal force of the rotating filter frame 6, together with the inner filter element 7, achieves the filtration and separation of the crystallization mother liquor. The separated liquid thrown out by the centrifugal force flows into the lower chamber 1 through the notches at the four corners of the connecting plate 4. At this time, the separated liquid is guided to the collection box 10 by the symmetrically distributed liquid guide plates 9 in the lower chamber 1. Finally, the collection box 10 can be pulled out from the lower chamber 1 by pulling the handle. Thus, the crystallization mother liquor can be efficiently filtered and recovered through the above structure. Furthermore, the L-shaped locking block 17 is moved by the lever moving the movable block 16. One end of block 17 will detach from the limiting slot 13 at one end of fixed block 12. Then, by lifting the upper box 2, the bottom of the upper box 2 can be removed from the lower box 1, thus facilitating the separation of the lower box 1 and the upper box 2. Separating the lower box 1 and the upper box 2 makes it easier for staff to clean the inside of the device. Finally, during assembly, the movable block 16 is moved by the lever to drive the L-shaped locking block 17 to move. Then, the bottom of the upper box 2 is inserted into the inside of the lower box 1. At this time, by releasing the lever, the L-shaped locking block 17 will pop out under the action of spring 15, so that one end of the L-shaped locking block 17 is inserted into the limiting slot 13 at the end of fixed block 12, thereby achieving fixation.
[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
