Description

Technical Field

[0001] This utility model relates to an alginate preparation device, belonging to the field of alginate preparation equipment. Background Technology

[0002] Alginic acid solution is a homogeneous mixture of alginic acid dispersed in a solvent. In the preparation of alginic acid, the alginic raw material must first be pretreated by washing, drying, and crushing to increase the reaction contact area. Then, an acidification reaction is carried out. The crushed alginic acid is placed in an acid-resistant container and an inorganic acid solution is added to convert the alginate into alginic acid precipitate. After the reaction is completed, the process proceeds to the pressure filtration stage. The purpose of pressure filtration is to separate the alginic acid precipitate from the reaction liquid. Through pressure filtration, a large amount of liquid impurities can be initially removed to obtain an alginic acid filter cake. The filter cake is then further purified by washing, drying, and other refining operations to further improve the purity of the alginic acid.

[0003] Traditional equipment often only performs unidirectional compression filtration of seaweed raw materials from top to bottom during the pressure filtration process. The filtration area is limited, and some raw materials may block the filter holes due to compression. As a result, the seaweed acid solution that is filtered out cannot be discharged quickly, and a large amount of seaweed acid remains in the raw materials, which not only wastes resources but also reduces the production efficiency of seaweed acid solution.

[0004] In summary, this invention provides an alginate preparation apparatus to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an alginate preparation device to solve the problem mentioned in the background technology that the filtered alginate solution cannot be discharged quickly due to unidirectional pressure filtration.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an alginate preparation device, comprising a base plate, with load-bearing rods fixedly installed around the top of the base plate, a top plate fixedly installed between the tops of the four load-bearing rods, load-bearing plates fixedly installed on both sides of the top of the base plate, a collection bucket installed between the tops of two load-bearing plates, a filter bucket penetrating the top of the collection bucket, a first filter plate fixedly embedded in the bottom of the filter bucket, a lifting and pressing filter assembly fixedly installed at the bottom of the top plate and directly above the filter bucket, a pump body fixedly installed on one side of the collection bucket and connected to the lifting and pressing filter assembly, a delivery pipe connected to the liquid outlet of the pump body, one end of the delivery pipe penetrating a load-bearing plate and extending to the bottom of the collection bucket.

[0007] Furthermore, the conveying pipe is connected to the collection bucket, and the bottom of the collection bucket is shaped like an inverted bucket.

[0008] Furthermore, the bottom center of the collection tank is connected to a liquid outlet pipe, and the delivery pipe is fixedly connected to the load-bearing plate.

[0009] Furthermore, the lifting and filtration assembly includes two electric lifting rods, which are respectively fixedly installed on both sides of the bottom of the top plate. A sealing plate is fixedly installed between the output ends of the two electric lifting rods. A filter barrel is fixedly installed at the bottom of the sealing plate. A second filter plate is fixedly embedded at the bottom of the filter barrel. An annular scraper is fixedly fitted at the bottom of the outer surface of the filter barrel. A liquid extraction pipe passes through the center of the top of the sealing plate. A telescopic hose connects the top end of the liquid extraction pipe to the liquid inlet end of the pump body.

[0010] Furthermore, a first sealing ring is fixedly fitted on the top of the outer ring surface of the annular scraper, and the outer diameter of the sealing plate fitted with the first sealing ring is equal to the inner diameter of the filter barrel.

[0011] Furthermore, the bottom end of the liquid extraction tube extends to the top of the second filter plate, and the liquid extraction tube is fixedly connected to the sealing plate.

[0012] Furthermore, the outer diameter of the annular scraper is equal to the inner diameter of the filter barrel, and a second sealing ring is fixedly fitted on the outer ring surface of the sealing plate.

[0013] The beneficial effects of this utility model are:

[0014] By moving the filter press barrel down into the filter barrel, the distance between the bottom of the filter press barrel and the bottom of the filter barrel is shortened. When the raw material for preparing alginate is filtered from top to bottom using the second filter plate at the bottom of the filter press barrel and the first filter plate at the bottom of the filter barrel, the excess filtrate can be discharged through the filter holes of the second filter plate at the top, which increases the filtration area. Bidirectional filtration improves the filtration efficiency of alginate solution and effectively improves the production efficiency of alginate solution. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an alginate preparation device, including a base plate 1, with load-bearing rods 2 fixedly installed around the top of the base plate 1, a top plate 3 fixedly installed between the tops of the four load-bearing rods 2, load-bearing plates 4 fixedly installed on both sides of the top of the base plate 1, a collection bucket 5 installed between the tops of two load-bearing plates 4, a filter bucket 6 penetrating through the top of the collection bucket 5, a first filter plate 7 fixedly embedded in the bottom of the filter bucket 6, a lifting and pressing filter assembly 8 fixedly installed at the bottom of the top plate 3 and directly above the filter bucket 6, and a pump body 9 fixedly installed on one side of the collection bucket 5, communicating with the lifting and pressing filter assembly 8. The liquid outlet is connected to a conveying pipe 10. One end of the conveying pipe 10 passes through a load-bearing plate 4 and extends to the bottom of the collection tank 5. The conveying pipe 10 is connected to the collection tank 5 and plays a key role in circulating and conveying the liquid during the preparation process. The design of the collection tank 5 fully considers the convenience of liquid collection and discharge. Its bottom is shaped like an inverted bucket. This shape is conducive to the liquid in the collection tank 5 flowing to the bottom center under the action of gravity, which facilitates the subsequent discharge operation. The bottom center of the collection tank 5 is connected to a liquid outlet pipe 11. A valve is installed on the liquid outlet pipe 11 to facilitate the discharge of the prepared alginic acid from the device. The conveying pipe 10 is fixedly connected to the load-bearing plate 4.

[0023] Please see Figure 2-3The lifting filter press assembly 8 includes two electric lifting rods 81, which are fixedly installed on both sides of the bottom of the top plate 3. Both electric lifting rods 81 are connected to an external power source and are equipped with the same power control switch. A sealing plate 82 is fixedly installed between the output ends of the two electric lifting rods 81. A filter press 83 is fixedly installed at the bottom of the sealing plate 82. A second filter plate 84 is fixedly embedded at the bottom of the filter press 83. An annular scraper 85 is fixedly fitted onto the bottom of the outer surface of the filter press 83. The top of the sealing plate 82... A liquid extraction pipe 88 runs through the center of the filter press 9. A flexible hose 89 connects the top of the liquid extraction pipe 88 to the inlet of the pump body 9. Both the first filter plate 7 and the second filter plate 84 are made of stainless steel mesh, which effectively filters out large particles of impurities in the seaweed raw material, such as incompletely crushed seaweed fragments and sand, providing a relatively pure raw material liquid for subsequent preparation processes. When the electric lifting rod 81 lowers the filter press 83 for filtration, the pump body 9 starts, and the filter material is filtered through the liquid extraction pipe 88 and the flexible hose 89. The liquid filtered by the second filter plate 84 in the barrel 83 is extracted and then transported to the bottom of the collection barrel 5 through the conveying pipe 10, realizing the circulation filtration and collection of the liquid. The top of the outer ring surface of the annular scraper 85 is fixedly fitted with a first sealing ring 86. The outer diameter of the sealing plate 82 fitted with the first sealing ring 86 is equal to the inner diameter of the filter barrel 6. The bottom end of the liquid extraction pipe 88 extends to the top of the second filter plate 84 and is fixedly connected to the sealing plate 82. The outer diameter of the annular scraper 85 is equal to the inner diameter of the filter barrel 6. A second sealing ring 87 is fixedly fitted on the outer ring surface of the sealing plate 82. When the filter press 83 descends, the annular scraper 85 can closely adhere to the inner wall of the filter press 6 to scrape off the impurities attached to the inner wall of the filter press 6, preventing impurities from being re-mixed into the liquid. At the same time, the outer diameter of the sealing plate 82, which is fitted with the first sealing ring 86, is equal to the inner diameter of the filter press 6, further enhancing the sealing effect and preventing liquid leakage. The outer ring surface of the sealing plate 82 is also fixedly fitted with the second sealing ring 87. The double sealing structure ensures the sealing performance of the entire filtration process.

[0024] Specific implementation method: By putting the seaweed raw material into the filter tank 6, the first filter plate 7 at the bottom of the filter tank 6 begins to play a preliminary filtration role. The first filter plate 7 is made of stainless steel filter mesh material, and its mesh can filter out large particulate impurities in the seaweed raw material, such as incompletely crushed seaweed fragments, sand and gravel, etc., so that the raw material liquid entering the subsequent process is purer.

[0025] When the external power supply is connected, the two electric lifting rods 81 are started by the power control switch. The electric lifting rods 81 are installed on both sides of the bottom of the top plate 3. After starting, their output ends drive the sealing plate 82 and the filter barrel 83 below to descend. During the descent, the annular scraper 85, because its outer diameter is equal to the inner diameter of the filter barrel 6, will stick tightly to the inner wall of the filter barrel 6 and scrape off the impurities attached to the inner wall to prevent them from being mixed into the liquid again. At the same time, the first sealing ring 86 and the second sealing ring 87 on the sealing plate 82 play a sealing role. The first sealing ring 86 is located at the top of the outer ring surface of the annular scraper 85. The outer diameter of the sealing plate 82 on which it is fitted is equal to the inner diameter of the filter barrel 6. The second sealing ring 87 is fixed on the outer ring surface of the sealing plate 82. The double seal ensures that the liquid will not leak during the filtration process.

[0026] After the filter press 83 descends to its position, the seaweed raw material is squeezed by the compression between the second filter plate 84 at the bottom of the filter press 83 and the first filter plate 7 at the bottom of the filter barrel 6. Part of the alginic acid solution will be directly transported to the bottom of the collection barrel 5, while the other part of the alginic acid solution will remain at the top of the second filter plate 84. Therefore, the pump body 9 needs to be started. Once the pump body 9 is started, it will extract the liquid filtered by the second filter plate 84 from the filter press 83 through the liquid extraction pipe 88 and the telescopic hose 89. The extracted liquid will be transported to the bottom of the collection barrel 5 through the delivery pipe 10 via the pump body 9. The bottom of the collection barrel 5 is shaped like an inverted bucket, which helps the liquid to flow to the center of the bottom under the action of gravity. By opening the valve on the liquid outlet pipe 11, the prepared alginic acid can be discharged from the device, thus completing the preparation of alginic acid.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
