Description

Technical Field

[0001] This invention relates to the field of water-retaining agent mixing technology, specifically a preparation machine for producing diatom-based water-retaining agents. Background Technology

[0002] Diatomaceous earth-based water-retaining agents are water-retaining materials made from natural porous diatomaceous earth as an important component, often combined with raw materials such as acrylamide, acrylic acid, and starch. After starch gelatinization, they are mixed with other components, grafted, copolymerized, and then dried. Their water absorption principle is similar to that of general superabsorbent resins. They rely on the affinity of hydrophilic groups such as amide and carboxyl groups on the polymer chain for water molecules, as well as the osmotic pressure generated by the concentration difference between the resin's internal ions and the aqueous solution to achieve a large amount of water absorption. They have the characteristics of large water absorption, high structural strength after water absorption, and resistance to breakage. Moreover, because they use biodegradable polymer materials and natural diatomaceous earth, they are environmentally friendly and easily degraded. In the fields of agriculture and horticulture, they can be used as soil conditioners to improve the soil's water and fertilizer retention capacity and for soilless cultivation. In forestry, they can improve the survival rate of transplanted seedlings. They can also be used in the production of hygiene products, concrete water retention, and cosmetic moisturizing.

[0003] Chinese patent publication number CN212396573U discloses a "stirring device for producing water-retaining agent," which includes a housing fixed to the top of a stirring drum, a feed hopper installed on the housing, a motor fixed to the housing, and a rotating shaft connected to the motor. The rotating shaft is rotatably connected to the stirring drum. This patent utilizes the rotation of the stirring blades to drive a fan-shaped top block to rotate and abut against the side wall of a fixed block, causing the fixed block to move away from the stirring blades. This causes a baffle to move towards the inner wall of the stirring drum, compressing a spring. At this time, the water-retaining agent material inside the stirring drum moves towards the inner wall of the stirring drum. After the top block rotates away from the fixed block, the spring force pushes the top block towards the stirring blades, pushing the water-retaining agent material inside the stirring drum towards the stirring blades. This process repeats, causing the water-retaining agent inside the stirring drum to tumble repeatedly in the horizontal direction during stirring, improving the stirring efficiency of the water-retaining agent material, facilitating uniform mixing, and thus benefiting the preparation of the water-retaining agent.

[0004] Although the aforementioned patent enables the stirring blades to move and stir repeatedly, if the stirring blades cannot be adjusted, there will be a fixed gap between the stirring blades and the container. If the gap is too small, the mixture on the wall of the water-retaining agent reactor will slip, stagnate, and create a blind zone in the center of the stirring. If the gap is too large, it will cause a large area of ​​stirring dead corners around the inner wall of the water-retaining agent reactor and low mixing efficiency. At the same time, a large amount of water-retaining agent will adhere to the inner wall of the water-retaining agent reactor, resulting in waste of raw materials.

[0005] To address this, a preparation machine for producing diatom-based water-retaining agents is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a preparation machine for producing diatom-based water-retaining agents, so as to solve the problems mentioned in the background art.

[0008] Furthermore, the adjustable stirring assembly also includes four sliding T-shaped rods, each of which is fixedly connected to the top of the second connecting rod. A second fixed cylinder is symmetrically fixedly connected to the outer side of the first fixed cylinder, and a second sliding cylinder is symmetrically fixedly connected to the top of the fixed protrusion. A spring is fixedly connected to the top of the inner cavity of each second fixed cylinder.

[0009] Furthermore, the inner cavity of the water-retaining agent reactor is provided with an anti-adhesion component, which includes multiple rubber blocks. The number of the multiple rubber blocks is half the number of the first connecting rods. Each rubber block is fixedly installed on each of the first connecting rods located at the bottom of the fixed protrusion. A porous filter plate is fixedly connected to the bottom of the first sliding cylinder.

[0010] Furthermore, the anti-adhesion component also includes a sliding circular plate, which is fixedly connected to the outside of the porous filter plate, and a universal rotating ball is fixedly installed at the bottom of each of the first sliding cylinders.

[0011] Furthermore, the outer side of the water-retaining agent reactor is provided with an inlet, which has a through structure and is connected to an external conveying mechanism. The conveying mechanism is a prior art device that only serves to transport zeolite powder, peat ash, lignite powder, and water into the water-retaining agent reactor. The outer side of the water-retaining agent reactor is provided with a water-retaining agent outlet, which has a through structure and is connected to a storage tank. The storage tank is a prior art device that only serves to hold the mixed solution inside the water-retaining agent reactor. The water-retaining agent outlet is located on the movement path of the arc-shaped stirring plate, and the size of the water-retaining agent outlet is adapted to the size of the arc-shaped stirring plate.

[0012] Furthermore, the four rectangular openings are arranged in a circular array with the center of the disk as a reference, the size of the disk is adapted to the inner diameter of the water-retaining agent reactor, and the four fixed protrusions are arranged in a circular array with the center of the first sliding cylinder as a reference.

[0013] Furthermore, the outer arc surface of each arc-shaped stirring plate is adapted to the inner arc surface of the water-retaining agent reaction vessel.

[0014] Furthermore, the outer side of each of the sliding T-shaped rods is slidably adapted to the rectangular opening, and the four sliding T-shaped rods are also arranged in a circular array with the center of the first sliding cylinder as a reference. The bottom of each spring is fixedly connected to the second sliding cylinder, and the outer side of each of the second sliding cylinders is slidably adapted to the second fixed cylinder.

[0015] Furthermore, the porous filter plate is located on the movement path of the rubber blocks, and the multiple rubber blocks are arranged in a ring array with the center of the first fixed cylinder as a reference.

[0016] Furthermore, the bottom of the inner cavity of the water-retaining agent reactor is located on the movement path of the universal rotating ball, and the size of the sliding circular plate is adapted to the inner cavity size of the water-retaining agent reactor.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The adjustable stirring assembly allows for the adjustment of the distance between the arc-shaped stirring plate and the inner wall of the water-retaining agent reactor. This enables flexible adaptation of the stirring gap to the reactor's specifications. Its core advantage lies in overcoming the limitations of fixed gaps. Firstly, it avoids slippage, stagnation, and blind spots in the central stirring area caused by excessively close gaps, while also preventing large-area stirring dead zones and low mixing efficiency around the reactor's inner wall due to excessively large gaps. Secondly, precise distance adjustment ensures that the stirring action fully covers the entire area inside the reactor, from the wall and bottom to the center. This improves the uniformity and efficiency of the mixture, reduces overload or component wear caused by unsuitable gaps, and significantly enhances the flexibility, adaptability, and practicality of the stirring operation.

[0019] The adjustable stirring assembly, combined with the anti-adhesion assembly, achieves the following: First, the collision between the rubber block and the porous filter plate knocks off the mixture adhering to the surface of the porous filter plate. Simultaneously, as the electric slide moves vertically downwards, the sliding disc begins to scrape the mixture along the inner wall of the water-retaining agent reactor, preventing it from adhering. Higher sections of the inner wall are scraped by the disc, ensuring that the entire inner wall of the reactor is free of mixture adhesion. Simultaneously, with the arc-shaped stirring plate fully extended and the stepper motor continuously rotating, the arc-shaped stirring plate constantly passes over the surface of the water-retaining agent outlet, preventing blockage of the outlet. Therefore, the materials used in the entire water-retaining agent preparation process are utilized to the maximum extent, and the prepared water-retaining agent is collected to the greatest extent possible.

The four rectangular openings 403 are arranged with the center of the disc 402 as a reference. The disc 402 is arranged in a ring array, with its size matching the inner diameter of the water-retaining agent reactor 2. Four fixed protrusions 406 are arranged in a ring array with the center of the first sliding cylinder 405 as a reference. Two sets of first connecting rods 407 are rotatably connected to the outer side of each fixed protrusion 406. The number of first connecting rods 407 in each set is not less than two, and every two first connecting rods 407 are symmetrically arranged with the center of the fixed protrusion 406 as a reference. A second connecting rod 408 is rotatably connected to the end of every two sets of first connecting rods 407 away from the fixed protrusion 406. The number of second connecting rods 408 is not less than four. An arc-shaped stirring plate 410 is fixedly connected to the end of each second connecting rod 408 away from the first connecting rod 407. The outer arc surface of each arc-shaped stirring plate 410 is matched with the inner arc surface of the water-retaining agent reactor 2.

[0040] The adjustable stirring assembly 4 also includes four sliding T-shaped rods 409. The outer side of each sliding T-shaped rod 409 is slidably adapted to the rectangular opening 403. The four sliding T-shaped rods 409 are also arranged in a circular array with the center of the first sliding cylinder 405 as a reference. Each sliding T-shaped rod 409 is fixedly connected to the top of the second connecting rod 408.

The outer side of each second sliding cylinder 412 is slidably adapted to the second fixed cylinder 411.

[0041] The inner cavity of the water-retaining agent reaction vessel 2 is provided with an anti-adhesion component 5. The anti-adhesion component 5 includes multiple rubber blocks 501. The number of multiple rubber blocks 501 is half the number of first connecting rods 407. Each rubber block 501 is fixedly installed on each of the first connecting rods 407 located at the bottom of the fixed protrusion 406. A porous filter plate 503 is fixedly connected to the bottom of the first sliding cylinder 405. The porous filter plate 503 is located on the movement path of the rubber blocks 501. The multiple rubber blocks 501 are arranged in a ring array with the center of the first fixed cylinder 404 as a reference.

[0042] The anti-adhesion component 5 also includes a sliding circular plate 502, which is fixedly connected to the outside of the porous filter plate 503. A universal rotating ball 504 is fixedly installed at the bottom of each first sliding cylinder 405. The bottom of the inner cavity of the water-retaining agent reactor 2 is located on the movement path of the universal rotating ball 504. The size of the sliding circular plate 502 is adapted to the inner cavity size of the water-retaining agent reactor 2.

[0043] An inlet 6 is provided on the outside of the water-retaining agent reactor 2. The inlet 6 has a through structure and is connected to an external conveying mechanism. The conveying mechanism is a prior art device that only serves to transport zeolite powder, peat ash, lignite powder, and water into the water-retaining agent reactor 2. The inlet 6 is located vertically below the disc 402. A water-retaining agent outlet 7 is provided on the outside of the water-retaining agent reactor 2. The water-retaining agent outlet 7 has a through structure and is connected to a storage tank. The storage tank is a prior art device that only serves to hold the mixed solution in the water-retaining agent reactor 2. The storage tank can transfer the solution in the water-retaining agent reactor 2 by a suction pump. The water-retaining agent outlet 7 is located on the movement path of the arc-shaped stirring plate 410, and the size of the water-retaining agent outlet 7 is adapted to the size of the arc-shaped stirring plate 410.

[0044] The working principle of the above implementation is as follows:

[0045] The initialization steps are as follows:

[0046] Spring 413 was not extended or retracted.

[0047] The operation steps are as follows:

[0048] The operating steps of the adjustable stirring component 4 are as follows:

[0049] As described in the above embodiments, when the worker puts zeolite powder, peat ash, lignite powder and water into the inner cavity of the water-retaining agent reactor 2 through the feed port 6, the worker first drives the stepper motor 401. At this time, the stepper motor 401 starts to rotate clockwise after being powered on. Therefore, the stepper motor 401 drives the disc 402 to rotate clockwise synchronously through its output shaft. When the disc 402 rotates clockwise, the disc 402 pushes the sliding T-shaped rod 409 to rotate clockwise through the rectangular opening 403. Similarly, the sliding T-shaped rod 409 drives the second connecting rod 408 to rotate clockwise. Therefore, the second connecting rod 408 drives the arc-shaped stirring plate 410 to start stirring the solution in the water-retaining agent reactor 2, thereby forming a mixture of zeolite powder, peat ash, lignite powder and water, which will be referred to as a mixture in the following text.

[0050] After continuous stirring for a period of time, the stepper motor 401 stops rotating first. Then, the operator starts the electric slide 301. At this time, the electric slide 301 drives the fixed plate 302 to move vertically downward through its output shaft. This causes the fixed plate 302 to drive the stepper motor 401 vertically downward, and simultaneously the stepper motor 401 drives the disc 402 vertically downward. Therefore, the disc 402 drives the first fixed cylinder 404 vertically downward, which in turn drives the second fixed cylinder 411 vertically downward. Meanwhile, the spring 413 remains in an unextended state. At this moment, the first sliding cylinder 405 also moves vertically downward. When the bottom of the first sliding cylinder 405... When the part of the water-retaining agent reactor 2 comes into contact with the bottom of the inner cavity, the universal rotating ball 504 comes into contact with the bottom of the inner cavity of the water-retaining agent reactor 2 before the first fixed cylinder 404. As the electric slide 301 continues to move downward, the first fixed cylinder 404 cannot continue to move vertically downward because it is in contact with the bottom of the inner cavity of the water-retaining agent reactor 2. As a result, the continuous downward movement of the first fixed cylinder 404 begins to push the second fixed cylinder 411. The second fixed cylinder 411 begins to slide vertically downward on the outside of the second sliding cylinder 412. The second fixed cylinder 411 also begins to compress the spring 413. Therefore, the first fixed cylinder 404 drives the disc 402 to move vertically downward as well.

[0051] As the disc 402 moves vertically downwards by contacting the sliding T-shaped rod 409, the sliding T-shaped rod 409 also drives the second connecting rod 408 to move vertically downwards. Therefore, the second connecting rod 408 begins to rotate counterclockwise around the connection point between the first connecting rod 407 and the fixed protrusion 406. At this time, the horizontal distance between the first connecting rod 407 and the fixed protrusion 406 continuously increases, thus pushing the second connecting rod 408 away from the fixed protrusion 406. Consequently, the second connecting rod 408 causes the sliding T-shaped rod 409 to slide within the rectangular opening 403. Inside, the sliding T-shaped rod 409 moves away from the center of the disc 402, so the second connecting rod 408 drives the arc-shaped stirring plate 410 to move away from the fixed protrusion 406. Finally, the four arc-shaped stirring plates 410 abut against the inner wall of the water-retaining agent reactor 2, so the displacement of the arc-shaped stirring plate 410 can be adjusted along with the vertical downward movement of the electric slide table 301. Then, the operator starts the stepper motor 401 again and repeats the above working steps, so that the first fixed cylinder 404 drives the universal rotating ball 504 to roll at the bottom of the inner cavity of the water-retaining agent reactor 2.

[0052] The adjustable stirring component 4 allows for the adjustment of the distance between the arc-shaped stirring plate 410 and the inner wall of the water-retaining agent reactor 2. This enables flexible adaptation of the stirring gap according to the specifications of the water-retaining agent reactor 2. Its core advantage lies in overcoming the limitations of a fixed gap. Firstly, it avoids slippage, stagnation, and blind spots in the mixing of the mixture on the wall of the water-retaining agent reactor 2 caused by an excessively close gap. It also prevents large-area stirring dead zones and low mixing efficiency around the inner wall of the water-retaining agent reactor 2 caused by an excessively far gap. Secondly, by precisely adjusting the distance, the stirring action can fully cover the entire area inside the water-retaining agent reactor 2, from the wall and bottom to the center. This improves the uniformity and efficiency of the mixture mixing and reduces overload or component wear caused by unsuitable gaps, significantly enhancing the flexibility, adaptability, and practicality of the stirring operation.

[0053] The working steps of the anti-adhesion component 5 are as follows:

[0054] Along with the above-described working steps, when the first connecting rod 407 rotates counterclockwise around the connection point between the first connecting rod 407 and the fixed protrusion 406, the first connecting rod 407 drives the rubber block 501 to move closer to the porous filter plate 503. Simultaneously, the mixture poured into the inner cavity of the water-retaining agent reactor 2 passes through the porous filter plate 503 and enters the bottom of the inner cavity of the water-retaining agent reactor 2. Therefore, the porous filter plate 503 prevents the mixture from remaining on the upper surface of the sliding circular plate 502 and failing to reach the bottom of the inner cavity of the water-retaining agent reactor 2. At the same time, the rubber block 501... As the first connecting rod 407 moves, the adhesive block 501 collides with the porous filter plate 503, knocking off the mixture adhering to the surface of the porous filter plate 503. Similarly, as the electric slide 301 moves vertically downward, the sliding disc 502 begins to scrape off the mixture along the inner wall of the water-retaining agent reactor 2, preventing the mixture from adhering to the inner wall of the water-retaining agent reactor 2. At the same time, the higher parts of the inner wall of the water-retaining agent reactor 2 are scraped off by the disc 402, so that the inner wall of the water-retaining agent reactor 2 is not allowed to be adhered to by the mixture.

[0055] Simultaneously, as the arc-shaped stirring plate 410 is fully extended and the stepper motor 401 rotates continuously, the arc-shaped stirring plate 410 continuously passes over the surface of the water-retaining agent outlet 7, thereby preventing the water-retaining agent outlet 7 from causing blockage of the mixture.

[0056] Finally, after the mixture has been stirred for a certain period of time, a water-retaining agent is formed through a polymerization reaction. At this point, the staff will turn on the suction pump in the storage tank to suck up and store the water-retaining agent.

[0057] The adjustable stirring assembly 4, combined with the anti-adhesion assembly 5, achieves the following: First, the collision between the rubber block 501 and the porous filter plate 503 knocks off the mixture adhering to the surface of the porous filter plate 503. Simultaneously, as the electric slide 301 moves vertically downwards, the sliding disc 502 begins to scrape the mixture along the inner wall of the water-retaining agent reactor 2, preventing the mixture from adhering to the inner wall. Higher sections of the inner wall are scraped by the disc 402, ensuring that the inner wall of the water-retaining agent reactor 2 is completely free of mixture adhesion. Simultaneously, with the arc-shaped stirring plate 410 fully extended and the stepper motor 401 continuously rotating, the arc-shaped stirring plate 410 continuously passes over the surface of the water-retaining agent outlet 7, preventing blockage of the mixture at the outlet. Therefore, all materials in the entire water-retaining agent preparation process can be utilized to the maximum extent, and the prepared water-retaining agent can be collected to the greatest extent possible.
