Description

Technical Field

[0001] This utility model relates to the field of humic acid production technology, and in particular to a precipitation device for humic acid production. Background Technology

[0002] Precipitation devices for humic acid production are key equipment in the process, playing a crucial role in solid-liquid separation in the mixed solution. These devices primarily use physical or chemical methods to precipitate solid substances from the mixed solution produced during humic acid production, thereby obtaining a high-purity humic acid product. In actual humic acid production processes, precipitation devices typically need to possess the following key structures and functions:

[0003] 1. As a core component, the sedimentation tank provides space for the sedimentation of the mixed liquor, and its structural design affects the sedimentation effect and treatment capacity.

[0004] 2. The stirring system is used to thoroughly stir the mixture in the early stage of sedimentation, promote the reaction, and improve the uniformity of sedimentation;

[0005] 3. The scraping device is responsible for scraping and collecting the sediment at the bottom of the sedimentation tank after sedimentation is completed, so as to facilitate subsequent processing;

[0006] 4. The feeding and discharging system ensures a stable input of the mixed liquid and a smooth output of the treated liquid and precipitate.

[0007] Currently, various technologies and equipment are employed in the industry to improve the performance of sedimentation devices used in humic acid production. Some manufacturers have adopted integrated stirring and sedimentation units, which improve the mixing effect of the ingredients through stirring, allowing for more complete reaction and thus increasing the efficiency of sedimentation operations to some extent. Other manufacturers use filter-pressure scraping sedimentation units, which can achieve rapid sedimentation of substances in the mixture, improving fertilizer production efficiency (humic acid can be used in fertilizer production). In addition, horizontal screw centrifuges, which operate continuously and automatically, are also widely used, offering advantages such as high separation efficiency and large processing capacity.

[0008] However, the existing technical solutions still have the following problems. In terms of production efficiency, the sedimentation speed of some sedimentation devices is slow, which leads to a longer production process time and affects the output per unit time. During the sedimentation process, the water flow path is short, and the solid particles in the mixture do not have enough time to settle to the bottom of the tank, which reduces sedimentation efficiency and product quality. Moreover, when some components of the sedimentation device, such as baffles and stirring blades, are damaged, the repair is difficult, especially for components that are difficult to disassemble, which takes a long time and seriously affects the normal operation of the equipment. In response to these problems, this application proposes an improved sedimentation device solution for humic acid production. By optimizing the structural design, it achieves functions such as extending the water flow path, improving production efficiency, and facilitating quick repair of damaged components, thereby improving the overall efficiency of humic acid production. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a sedimentation device for humic acid production. It solves the problems of slow sedimentation speed in some sedimentation devices, which leads to a longer production process time and affects the output per unit time. In the sedimentation process, the water flow path is short, and the solid particles in the mixed liquid do not have enough time to settle to the bottom of the tank, which reduces sedimentation efficiency and product quality.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A sedimentation device for humic acid production includes a sedimentation tank, a set of filter plates for sedimentation is provided in the sedimentation tank, a connecting frame is fixedly connected to the rear surface of the sedimentation tank, a lead screw is rotatably connected between the connecting frame and the sedimentation tank, a set of partitions is movably engaged in the sedimentation tank, a fixing strip is fixedly connected to the left surface of each partition, two limiting blocks are movably engaged in each fixing strip, and a return spring is fixedly connected to the opposite face of each of the two limiting blocks, a connecting strip is provided on the upper surface of the sedimentation tank, a push block is fixedly connected to the left surface of each pair of limiting blocks, a connecting rod is fixedly connected to the upper surface of each filter plate, and a set of connecting rods are fixedly connected to the connecting strip.

A motor is fixedly installed on the upper surface of the connecting frame, and the output shaft of the motor is fixedly connected to the lead screw, which is threadedly sleeved with the connecting strip.

[0013] Preferably, each of the fixing strips is fixedly connected to a fixing block, each fixing block is fixedly connected to each pair of reset springs, and the inner wall of the sedimentation tank is provided with two sets of slots, which are respectively engaged with two sets of limiting blocks.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. As the filter plate moves downward, it pushes the substances in the mixture to the bottom of the sedimentation tank to achieve rapid sedimentation. Rapid sedimentation can shorten the sedimentation time in the entire production process, allowing solid substances in the mixture to separate from the liquid more quickly. This enables subsequent processing steps, such as further processing of the precipitate or recycling of the supernatant, to be carried out more quickly, which helps to improve overall production efficiency and increase output per unit time.

[0016] 2. Pressing the two push blocks relative to each other moves the fixed limit blocks together, compressing the two return springs. At this time, the two limit blocks will disengage from the two slots opened on the inner wall of the sedimentation tank, opening the limit. The baffle can then be disassembled.

The easy-to-disassemble baffle allows maintenance personnel to quickly remove it, repair the damaged parts or directly replace the new baffle, reduce the downtime of the equipment and ensure the continuity of production.

[0023] This application provides a sedimentation device for humic acid production, which effectively solves the problems of slow sedimentation speed in some sedimentation devices, which leads to a longer production process time and affects the output per unit time. During the sedimentation process, the water flow path is short, and the solid particles in the mixture do not have enough time to settle to the bottom of the tank, which reduces sedimentation efficiency and product quality. By optimizing the structural design, the device can extend the water flow path, improve production efficiency, and facilitate the quick repair of damaged parts, thereby improving the overall efficiency of humic acid production. Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the sedimentation speed of some sedimentation devices is slow, which leads to a longer production process time and affects the output per unit time. During the sedimentation process, the water flow path is short, and the solid particles in the mixed liquid do not have enough time to settle to the bottom of the tank, which reduces the sedimentation efficiency and product quality. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a sedimentation device for humic acid production, including a sedimentation tank 1. A set of filter plates 3 for sedimentation is installed inside the sedimentation tank 1. A connecting frame 7 is fixedly connected to the rear surface of the sedimentation tank 1. A lead screw 9 rotatably connects the connecting frame 7 and the sedimentation tank 1. A set of partitions 2 are movably engaged inside the sedimentation tank 1. A fixing strip 10 is fixedly connected to the left surface of each partition 2. Two limiting blocks 13 are movably engaged within each fixing strip 10. Return springs 15 are fixedly connected to the opposite faces of the two limiting blocks 13. Connecting strips 5 are provided on the upper surface of the sedimentation tank 1. Push blocks 14 are fixedly connected to the left surface of each pair of limiting blocks 13. Connecting rods 4 are fixedly connected to the upper surface of each filter plate 3. A set of connecting rods 4 are fixedly connected to the connecting strips 5. During operation, starting the motor 6 causes its output shaft to drive the fixed lead screw 9 to rotate. As the lead screw 9 rotates, the connecting bar 5 sleeved on it moves due to the thread action. The movement of the connecting bar 5 drives a set of fixed connecting rods 4 to move together. The movement of the connecting rods 4 drives the fixed filter plate 3 to move together. As the filter plate 3 moves downward, it pushes the substances in the mixture to the bottom of the sedimentation tank 1 to achieve rapid sedimentation. Rapid sedimentation can shorten the sedimentation time in the entire production process, allowing the solid substances in the mixture to separate from the liquid more quickly. This enables subsequent processing steps, such as further processing of the precipitate or recycling of the supernatant, to be carried out more quickly, which helps to improve overall production efficiency and increase output per unit time.

[0026] Two positioning rods 8 are fixedly connected to the upper surface of the sedimentation tank 1. Both positioning rods 8 are movably sleeved with the connecting strip 5. A motor 6 is fixedly installed on the upper surface of the connecting frame 7. The output shaft of the motor 6 is fixedly connected to the lead screw 9. The lead screw 9 is threadedly sleeved with the connecting strip 5. A fixing block 16 is fixedly connected inside each fixing strip 10. Each fixing block 16 is fixedly connected to each pair of return springs 15. Two sets of slots 11 are opened on the inner wall of the sedimentation tank 1. The two sets of slots 11 are movably engaged with two sets of limit blocks 13. A set of partitions 2 is set inside the sedimentation tank 1 to divide it into multiple spaces. Dividing the sedimentation tank 1 into multiple spaces can effectively reduce short-circuiting and turbulence of water flow. The water in each space The relatively stable flow prevents the re-suspension of settled particles due to violent water flow disturbance, thereby improving the sedimentation effect. Pressing the two push blocks 14 moves the fixed limit blocks 13 together, compressing the two return springs 15. At this time, the two limit blocks 13 will disengage from the two slots 11 opened in the inner wall of the sedimentation tank 1, opening the limit. At this time, the baffle 2 can be disassembled. During the operation of the sedimentation tank 1, the baffle 2 may be damaged due to water flow impact, corrosion or other reasons. The easy-to-disassemble baffle 2 allows maintenance personnel to quickly remove it, repair the damaged parts or directly replace the new baffle 2, reduce the downtime of the equipment and ensure the continuity of production.

[0027] Among them, sedimentation tank 1: as the core component of the sedimentation device for humic acid production, it provides space for the sedimentation of mixed liquid. Its internal structure works in conjunction with other components to achieve solid-liquid separation, affecting the sedimentation effect and treatment capacity.

[0028] Baffle 2: Divides sedimentation tank 1 into multiple spaces, reduces short-circuiting and turbulence, improves sedimentation effect, and is easy to disassemble, making it convenient to repair damaged parts and ensuring production continuity;

[0029] Filter plate 3: Driven by motor 6, it moves downward, pushing the substances in the mixture to the bottom of sedimentation tank 1, achieving rapid sedimentation, shortening sedimentation time, and improving production efficiency;

[0030] Connecting rod 4: connects filter plate 3 and connecting bar 5. When connecting bar 5 moves, it drives filter plate 3 to move, thereby realizing the function of promoting the precipitation of substances in the mixture.

[0031] Connecting bar 5: It is threadedly connected to lead screw 9. When lead screw 9 rotates, it moves under the action of the thread, thereby driving connecting rod 4 and filter plate 3 to move. It is the key connecting component to realize the action of filter plate 3.

[0032] Motor 6: Provides power, and its output shaft drives the lead screw 9 to rotate, providing driving force for the movement of filter plate 3, enabling the sedimentation device to achieve rapid sedimentation function and improve production efficiency;

[0033] Connecting frame 7: Fixes motor 6 and rotatably connects to lead screw 9 with sedimentation tank 1, providing installation support structure for motor 6 and lead screw 9 to ensure stable operation of the device;

[0034] Positioning rod 8: It is movably sleeved with connecting bar 5, and plays a positioning and guiding role in the movement of connecting bar 5, ensuring that connecting bar 5 moves smoothly and that filter plate 3 works normally;

[0035] Lead screw 9: Driven by motor 6, it rotates and, through threaded engagement with connecting bar 5, converts the rotation of motor 6 into linear movement of connecting bar 5, thereby controlling the lifting and lowering of filter plate 3;

[0036] Fixed strip 10: Fixed on the partition 2, with internal components such as limit block 13 and return spring 15, used to realize the movable engagement and disassembly function between the partition 2 and the sedimentation tank 1;

[0037] Slot 11: It is movably engaged with the limiting block 13 to limit and fix the partition 2, so that the partition 2 remains stable in the sedimentation tank 1 and ensures the sedimentation effect.

[0038] Limiting block 13: It moves within the fixing strip 10 and cooperates with the slot 11 to limit the position of the partition 2. When the partition 2 needs to be removed, the limiting block 13 can be moved to release the restriction.

[0039] Push block 14: Connects to limit block 13. By pressing push block 14, limit block 13 can be moved, thereby realizing the disassembly operation of partition 2 and facilitating maintenance.

[0040] Return spring 15: Connects two limit blocks 13. It is compressed when the partition 2 is disassembled. After the push block 14 is released, the limit blocks 13 can be reset, which makes it easy for the partition 2 to be reinstalled and fixed.

[0041] Fixed block 16: Fixed inside the fixed strip 10, used to connect the reset spring 15, to ensure the stability of the reset spring 15 and enable it to perform its reset function normally.

[0042] Working principle:

[0043] During operation, starting the motor 6 causes its output shaft to rotate the fixed lead screw 9. As the lead screw 9 rotates, the connecting strip 5 sleeved on it moves due to the thread action. This movement of the connecting strip 5 causes a set of fixed connecting rods 4 to move together. The movement of the connecting rods 4 then causes the fixed filter plate 3 to move together. As the filter plate 3 moves downwards, it pushes the substances in the mixture to the bottom of the sedimentation tank 1, achieving rapid sedimentation. Rapid sedimentation shortens the sedimentation time in the entire production process, allowing solids in the mixture to separate from the liquid more quickly. This enables subsequent processing steps, such as further processing of the precipitate or recycling of the supernatant, to proceed more quickly, thus improving overall production efficiency and increasing output per unit time. The sedimentation tank 1 is equipped with a set of baffles 2 to separate the solids from the liquid. The sedimentation tank 1 is divided into multiple spaces, which effectively reduces short-circuiting and turbulence of the water flow. The water flow in each space is relatively stable, avoiding the re-suspension of settled particles due to violent water flow disturbance, thereby improving the sedimentation effect. Pressing the two push blocks 14 moves the fixed limit blocks 13 together, compressing the two return springs 15. At this time, the two limit blocks 13 will disengage from the two slots 11 opened in the inner wall of the sedimentation tank 1, opening the limit. At this time, the baffle 2 can be disassembled. During the operation of the sedimentation tank 1, the baffle 2 may be damaged due to water flow impact, corrosion or other reasons. The easy-to-disassemble baffle 2 allows maintenance personnel to quickly remove it, repair the damaged parts or directly replace the new baffle 2, reduce the downtime of the equipment and ensure the continuity of production.

[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
