Description

Technical Field

[0001] This utility model belongs to the technical field of impurity separation devices, specifically relating to an impurity separation device for calcium carbonate manufacturing. Background Technology

[0002] An impurity separation device is a piece of equipment that uses physical or chemical methods to separate impurities from the target substance in a mixture. It is widely used in water treatment, chemical industry, pulp and paper making, food processing, metallurgy, and many other fields. In the calcium carbonate manufacturing process, an impurity separation device (here, a screening device) is needed to screen the raw materials to reduce impurities and large particles, making it easier to use the raw materials to manufacture calcium carbonate.

[0003] However, there is a problem with the current impurity separation device: the screened raw material is discharged from the discharge hopper. During the discharge process, the raw material flows into the discharge hopper along the guide plate. However, due to the limited internal space of the discharge hopper, the flowing raw material is prone to clogging the discharge hopper, which leads to difficulties in discharging. Utility Model Content

[0004] The purpose of this invention is to provide an impurity separation device for calcium carbonate manufacturing, which aims to solve the problem in the prior art where the screened raw material is discharged from the discharge hopper. During the discharge process, the raw material flows into the discharge hopper along the guide plate, but due to the limited internal space of the discharge hopper, the flowing raw material easily clogs the discharge hopper, thus causing difficulty in discharging the material.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an impurity separation device for calcium carbonate manufacturing, comprising an impurity separation chamber, a feed hopper connected to the top of the impurity separation chamber, a discharge hopper connected to the bottom of the side wall of the impurity separation chamber, an observation window embedded in the front end of the impurity separation chamber, a filter screen inserted inside the impurity separation chamber, a guide plate connected to the bottom of the inner part of the impurity separation chamber, vibration springs installed at the four corners of the bottom of the impurity separation chamber, a vibration motor connected to the bottom of the impurity separation chamber, a U-shaped base provided at the bottom of the impurity separation chamber, the vibration springs connected to the U-shaped base, a first threaded rod rotatably connected to the discharge hopper near the side wall of the impurity separation chamber via a bearing, a threaded sleeve threadedly connected to the surface of the first threaded rod, and a dredging column connected to the threaded sleeve near the side wall of the impurity separation chamber.

[0006] As a preferred embodiment of the impurity separation device for calcium carbonate manufacturing according to this utility model, the threaded sleeve is rectangular, and the height of the threaded sleeve is the same as the internal height of the discharge hopper.

[0007] As a preferred embodiment of the impurity separation device for calcium carbonate production in the present utility model, the dredging columns extend into the impurity separation箱体, and four dredging columns are distributed longitudinally at equal intervals.

[0008] As a preferred embodiment of the impurity separation device for calcium carbonate production in the present utility model, a side wall of the impurity separation箱体 away from the discharge hopper is provided with a first chute, a first sliding block is slidably connected inside the first chute, a second threaded rod is rotatably connected inside the first chute via a bearing, a second chute is provided on a side wall of the impurity separation箱体 symmetrically with respect to the first chute, a second sliding block is slidably connected inside the second chute, a guide rod is installed inside the second chute, and a limit block in a shape of Chinese character "匚" is connected between front ends of the first sliding block and the second sliding block.

[0009] As a preferred embodiment of the impurity separation device for calcium carbonate production in the present utility model, an inner wall of the limit block fits against a surface of a protruding portion of the filter screen.

[0010] As a preferred embodiment of the impurity separation device for calcium carbonate production in the present utility model, the second threaded rod threadedly penetrates the first sliding block and is rotatably connected inside the first chute, and the guide rod penetrates the second sliding block and is connected inside the second chute.

[0011] As a preferred embodiment of the impurity separation device for calcium carbonate production in the present utility model, the limit block can form a sliding connection with the impurity separation箱体 through the first sliding block and the second sliding block.

[0012] Compared with the prior art, the beneficial effects of the present utility model are: Through the cooperation among the first threaded rod, the threaded sleeve and the dredging columns, an operator only needs to rotate the first threaded rod, and the threaded sleeve will move stably along the thread track on the surface of the first threaded rod. Since the dredging columns are closely connected with the threaded sleeve, the dredging columns move synchronously with the threaded sleeve, and because the dredging columns extend into the impurity separation箱体, the dredging columns can effectively dredge raw materials blocked at the connection between the impurity separation箱体 and the discharge hopper when moving, which avoids blockage of the discharge hopper, effectively ensures smooth blanking, and greatly improves the stability and efficiency of equipment operation.

[0013] Through the coordinated operation of the first slide rail, the first slider, the second threaded rod, the second slide rail, the second slider, the guide rod, and the limiting block, when the operator rotates the second threaded rod clockwise, the first slider will move smoothly along the surface of the second threaded rod. Since the first slider is connected to the limiting block, its movement will drive the limiting block to move as well. Then, the limiting block will drive the second slider to move along the surface of the guide rod, causing the limiting block to move away from the protruding part of the filter screen. This greatly simplifies the disassembly and assembly process of the filter screen when it is damaged or clogged, making it convenient for the operator to deal with the filter screen in a timely manner, effectively shortening the equipment maintenance and cleaning time, and improving work efficiency. When the second threaded rod is rotated counterclockwise, with the filter screen inserted into the impurity separation box, the limiting block will move to the protruding part of the filter screen, thereby achieving a stable fixation of the filter screen and ensuring that the filter screen will not shift during operation, thus guaranteeing the normal operation and filtration effect of the impurity separation device.

[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 Figures 1-5 This utility model provides the following technical solution: an impurity separation device for calcium carbonate manufacturing, comprising an impurity separation box 1, a feed hopper 2 connected to the top of the impurity separation box 1, a discharge hopper 3 connected to the bottom of the side wall of the impurity separation box 1, an observation window 4 embedded in the front end of the impurity separation box 1, a filter screen 5 inserted inside the impurity separation box 1, a guide plate 6 connected to the bottom of the inside of the impurity separation box 1, vibration springs 7 installed at the four corners of the bottom of the impurity separation box 1, a vibration motor 8 connected to the bottom of the impurity separation box 1, a U-shaped base 9 provided at the bottom of the impurity separation box 1, the vibration springs 7 connected to the U-shaped base 9, a first threaded rod 10 rotatably connected to the discharge hopper 3 near the side wall of the impurity separation box 1 via a bearing, a threaded sleeve 11 threadedly connected to the surface of the first threaded rod 10, and a clearing column 12 connected to the threaded sleeve 11 near the side wall of the impurity separation box 1.

[0018] In practical use, the impurity separation device mainly consists of an impurity separation box 1, a feed hopper 2, a discharge hopper 3, an observation window 4, a filter screen 5, a guide plate 6, a vibration spring 7, a vibration motor 8, and a U-shaped base 9.

[0019] When using this device, the operator first feeds the raw materials required for calcium carbonate production into the device from the feed hopper 2. The raw materials will fall onto the filter screen 5. Then, the power supply is connected and the vibration motor 8 is started. The vibration motor 8 starts to work, and the vibration force generated by it, together with the vibration spring 7, causes the impurity separation box 1 to start vibrating. The vibrating impurity separation box 1 transmits the vibration force to the filter screen 5. The filter screen 5 vibrates accordingly and filters and screens the raw materials that fall onto its surface, thereby reducing impurities and large particles in the raw materials, which facilitates the subsequent production of calcium carbonate from the raw materials.

[0020] After being screened by the filter screen 5, the raw materials that meet the requirements will fall from the filter screen 5 and slide down the inclined surface of the guide plate 6 to the discharge hopper 3, and finally be discharged from the discharge hopper 3 to the outside of the device. In addition, the observation window 4 set on the device can facilitate the operator to observe the impurity separation and also check in time whether the discharge hopper 3 is blocked.

[0021] Preferably: the thread sleeve 11 is rectangular, and the height of the thread sleeve 11 is the same as the internal height of the discharge hopper 3. The dredging columns 12 extend into the interior of the impurity separation box 1, and four dredging columns 12 are distributed at equal longitudinal intervals.

[0022] In specific application, when an operator detects that the discharge hopper 3 is clogged through the observation window 4, the operator only needs to rotate the first threaded rod 10, and the thread sleeve 11 will move steadily along the thread track on the surface of the first threaded rod 10. Since the dredging column 12 is tightly connected to the thread sleeve 11, the dredging column 12 will move synchronously driven by the movement of the thread sleeve 11.

[0023] Since the dredging column 12 extends into the interior of the impurity separation box 1, when it starts to move, it can effectively dredge the raw material clogged at the connection between the impurity separation box 1 and the discharge hopper 3. This avoids continuous worsening of the clogging of the discharge hopper 3, effectively ensures that the blanking process can proceed smoothly, thereby greatly improving the operational stability of the impurity separation device and effectively enhancing the overall working efficiency of the equipment.

[0024] Preferably: a first sliding groove 13 is provided on the side wall of the impurity separation box 1 away from the discharge hopper 3, a first sliding block 14 is slidably connected inside the first sliding groove 13, a second threaded rod 15 is rotatably connected inside the first sliding groove 13 through a bearing, a second sliding groove 16 is symmetrically provided on the side wall of the impurity separation box 1 opposite to the first sliding groove 13, a second sliding block 17 is slidably connected inside the second sliding groove 16, a guide rod 18 is installed inside the second sliding groove 16, and a limiting block 19 in a shape of "匚" is connected between the front ends of the first sliding block 14 and the second sliding block 17. The inner wall of the limiting block 19 fits the surface of the protruding part of the filter screen 5. The second threaded rod 15 is threaded through the first sliding block 14 and rotatably connected inside the first sliding groove 13, the guide rod 18 penetrates the second sliding block 17 and connected inside the second sliding groove 16. The limiting block 19 can form a sliding connection with the impurity separation box 1 through the first sliding block 14 and the second sliding block 17.

[0025] In specific application, when an operator finds that the filter screen 5 is damaged through the observation window 4, the operator needs to stop the operation of the device first, then the operator rotates the second threaded rod 15 clockwise, and the first sliding block 14 will move smoothly along the surface of the second threaded rod 15. Since the first sliding block 14 is connected to the limiting block 19, the movement of the first sliding block 14 will drive the limiting block 19 to move synchronously, and then the limiting block 19 will drive the second sliding block 17 to move along the surface of the guide rod 18, so that the limiting block 19 is moved away from the surface of the protruding part of the filter screen 5.

[0026] This system plays a crucial role in simplifying the disassembly and assembly process of filter screen 5 when it becomes damaged or clogged. Operators can replace and clean filter screen 5 more conveniently and quickly, effectively shortening equipment maintenance and cleaning time and significantly improving overall work efficiency.

[0027] When the operator rotates the second threaded rod 15 counterclockwise, with the filter screen 5 already inserted into the impurity separation box 1, the limiting block 19 will move to the protruding surface of the filter screen 5, thereby achieving a stable fixation of the filter screen 5. This ensures that the filter screen 5 will not shift during operation, effectively guaranteeing the normal operation of the impurity separation device and a good filtration effect.

[0028] It is worth noting that the connection between the filter screen 5 and the impurity separation box 1 is a sealed connection to prevent raw materials from seeping into the gaps and affecting the disassembly and assembly of the filter screen 5.

[0029] Working principle: When the operator starts the work, the raw materials required for calcium carbonate production are first fed into the impurity separation device from the feed hopper 2. After the raw materials fall into the device, they will fall directly onto the filter screen 5. Then, the operator connects the power supply and starts the vibration motor 8. The vibration motor 8 starts to run, and the vibration force generated by it cooperates with the vibration spring 7 to cause the impurity separation box 1 to start vibrating. The vibrating impurity separation box 1 transmits the vibration force to the filter screen 5, causing the filter screen 5 to vibrate as well. This filters and screens the raw materials that fall onto its surface, separating the impurities from the raw materials. Through this process, impurities and large particles in the raw materials can be effectively reduced, creating convenient conditions for the subsequent use of the raw materials to manufacture calcium carbonate.

[0030] After being screened by the filter screen 5, the raw materials that meet the requirements will fall off the filter screen 5 and slide down the inclined surface of the guide plate 6 to the discharge hopper 3, and finally be discharged from the discharge hopper 3 to the outside of the device.

[0031] Furthermore, if the operator notices a blockage in the discharge hopper 3 through the observation window 4, the operator can rotate the first threaded rod 10. The threaded sleeve 11 will then move steadily along the threaded trajectory on the surface of the first threaded rod 10. Since the unblocking column 12 is tightly connected to the threaded sleeve 11, it will move synchronously under the movement of the threaded sleeve 11. Given that the unblocking column 12 extends into and into the interior of the impurity separation chamber 1, when it begins to move, it can effectively unblock the raw material blocking the connection between the impurity separation chamber 1 and the discharge hopper 3, preventing the blockage in the discharge hopper 3 from worsening. This ensures that the material feeding process can proceed smoothly and without obstruction, thereby greatly improving the operational stability of the impurity separation device and effectively enhancing the overall working efficiency of the equipment.

[0032] Meanwhile, when the operator discovers damage to the filter screen 5 through the observation window 4, the device must be stopped first. Then, the operator rotates the second threaded rod 15 clockwise. At this time, the first slider 14 will move smoothly along the surface of the second threaded rod 15. Since the first slider 14 is connected to the limiting block 19, the movement of the first slider 14 will drive the limiting block 19 to move synchronously. Then, the limiting block 19 will drive the second slider 17 to move along the surface of the guide rod 18, thereby causing the limiting block 19 to move away from the protruding part of the filter screen 5. This plays a huge role when the filter screen 5 is damaged or clogged, greatly simplifying the disassembly and assembly process of the filter screen 5. The operator can replace and clean the filter screen 5 more conveniently and quickly, effectively shortening the maintenance and cleaning time of the equipment and significantly improving the overall work efficiency.

[0033] Subsequently, after the filter screen 5 is reinstalled, the operator only needs to rotate the second threaded rod 15 counterclockwise to move the limiting block 19 to the protruding surface of the filter screen 5, thereby achieving a stable fixation of the filter screen 5.

[0034] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
