Description

Technical Field

[0001] This application relates to the field of chemical and pharmaceutical production equipment technology, specifically to an integrated filtration and washing device for rapid separation of calcium gluconate products. Background Technology

[0002] As an important pharmaceutical and food additive, the solid-liquid separation and filter cake washing after crystallization are key processes that determine the purity of calcium gluconate during its production. To improve production efficiency and reduce pollution and loss during material transfer, the industry generally adopts integrated filtration and washing devices, which integrate the processes of filtration and separation of crystallized liquid, filter cake washing, and finished product discharge into the same equipment.

[0003] Existing integrated calcium gluconate filtration and washing devices still have many shortcomings in practical applications: First, the spraying systems of existing devices are mostly fixed spray heads or single-direction spraying structures, with limited spray coverage. This easily creates spray blind spots on the filter cake surface, resulting in uneven washing of the filter cake. In some areas, residual mother liquor and impurities are difficult to remove completely, which not only affects product purity but also consumes a large amount of washing liquid, increasing production costs and wastewater treatment pressure. Second, the stirring mechanism inside the device usually only has a fixed height stirring function, which can only perform simple mixing of materials during the washing stage. It cannot adapt to the stirring requirements of filter cakes of different thicknesses. Moreover, an additional independent scraping mechanism is required to assist in the discharge, resulting in a complex equipment structure and a large footprint. At the same time, the additional scraping mechanism is prone to motion interference with other components, increasing the risk of equipment failure. It may also cause filter cake to remain on the inner wall of the equipment during the discharge process, affecting the continuity of subsequent production and product yield.

[0004] Therefore, it is necessary to provide an integrated filtration and washing device for rapid separation of calcium gluconate products to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is: to provide an integrated filtration and washing device for rapid separation of calcium gluconate products. During washing, the second hydraulic telescopic rod drives the stirring rod to move upward, and the first hydraulic telescopic rod drives the support plate to move upward to scrape the surface of the filter cake. The second motor drives the washing liquid spraying plate to swing in multiple directions through the rocker plate and guide ball, covering the filter cake without blind spots. The first motor drives the stirring rod to rotate and break up the filter cake, so that the washing liquid can fully penetrate and dissolve residual impurities, which is conducive to multi-directional spraying and washing of the filter cake and improves the washing efficiency of the filter cake. During filtration, the support plate moves down to the filter hole, the air pump introduces positive pressure, and the stirring rod moves down and rotates centrifugally, pushing the liquid through the double-layer filter screen for separation. The filtrate is discharged through the drain pipe. During discharge, the support plate carries the filter cake to the discharge port, and the scraping part of the stirring rod rotates to push the filter cake out. Then the stirring rod rotates up and down in a cycle to scrape off the residue on the inner wall. The telescopic stirring rod has both washing and stirring and discharge scraping functions, which is conducive to improving the waste liquid filtration speed and the cleanliness of the filter cake scraping.

[0007] The technical solution adopted by this application to solve its technical problem is: an integrated filtration and washing device for rapid separation of calcium gluconate product, including a device body, a cover connected to the top of the device body by a clamp, a hanging rod rotatably connected to the middle of the cover, a spray assembly that can swing in multiple directions at one end of the hanging rod for spraying and washing the filter cake in the device body without blind spots, a support plate that is slidably connected to the device body, a stirring rod that runs through the middle of the support plate, the stirring rod that can extend and retract along the axial direction of the device body, and has both the function of stirring and mixing materials and the function of scraping materials during discharge, a filter assembly in the middle of the device body for solid-liquid separation of calcium gluconate crystal slurry, and a feed hopper fixed at one end of the device body near the cover.

Two first hydraulic telescopic rods for driving the hoop plate to rise and fall are symmetrically distributed on the hoop plate. A protective base is fixed to the end of the main body of the device away from the hatch. Both the first and second hydraulic telescopic rods are installed and fixed inside the protective base.

[0010] Furthermore, the filter assembly includes a filter screen mounting box fixed in the middle of the device body. A sealing cap is connected to the filter screen mounting box by a threaded clamp. A first filter screen and a second filter screen are arranged sequentially from the inside to the outside along the direction close to the device body on the inner side of the filter screen mounting box.

[0011] Furthermore, the filter screen mounting box has a discharge port at one end facing the protective base, the discharge port is fixedly connected to the main body of the device, and a drain pipe for discharging filtrate is also fixed on the filter screen mounting box.

[0012] Furthermore, a heating tube is fitted above the wall cavity of the main body of the device. The heating tube is used to regulate the temperature of the material inside the main body of the device to adapt to the dissolution and crystallization characteristics of calcium gluconate.

[0013] Furthermore, the end of the stirring rod near the cover is provided with a scraping part adapted to the inner wall of the device body. When the stirring rod is extended or retracted to a position close to the inner wall of the device body, the scraping part can scrape off the filter cake remaining on the inner wall of the device body as the stirring rod rotates.

[0014] Furthermore, an air pump is installed and fixed on the hatch cover.

[0022] like Figure 1-5As shown, this application provides an integrated filtration and washing device for rapid separation of calcium gluconate product, including a main body 1. A cover 5 is connected to the top of the main body 1 via clamps. A lifting rod 7 is rotatably connected to the middle of the cover 5. One end of the lifting rod 7 is equipped with a multi-directionally swinging spray assembly for spraying and washing the filter cake inside the main body 1 without blind spots. A support plate 12 is slidably connected to the main body 1, and a stirring rod 13 is inserted through the middle of the support plate 12. The stirring rod 13 can extend and retract along the axial direction of the main body 1 and also has the functions of stirring and mixing materials and scraping materials during discharge. A filtration assembly is located in the middle of the main body 1 for solid-liquid separation of calcium gluconate slurry. A feed hopper 6 is fixed at one end of the main body 1 near the cover 5. The spray assembly includes an arc-shaped guide cover 21 fixed to one end of the boom 7, a conical protective cover 17 fixed inside the arc-shaped guide cover 21, a second motor 22 installed at the connection between the boom 7 and the arc-shaped guide cover 21, a rocker plate 23 fixed to the output end of the second motor 22, an infusion pipe 24 rotatably connected to one end of the rocker plate 23, a guide ball 25 fixed to one end of the infusion pipe 24, a washing liquid spraying disc 26 fixed to one end of the guide ball 25, a ball bearing cavity formed on the contact surface between the conical protective cover 17 and the guide ball 25, multiple balls rolling inside the ball bearing cavity, the guide ball 25 rotatably engaging with the conical protective cover 17, a liquid storage tank 27 located at the end of the conical protective cover 17 facing the rocker plate 23, and one end of the infusion pipe 24 connected to the liquid storage tank 27 via a hose, and a stirring rod 13 is located further away from the rocker plate 23. One end of the device body 1 is connected to a first motor 16 through the hatch cover 5. A second hydraulic telescopic rod 15 for driving the axial extension and retraction of the stirring rod 13 is installed at one end of the first motor 16. Two first hydraulic telescopic rods 14 for driving the lifting and lowering of the support plate 12 are symmetrically distributed on the support plate 12. A protective base 2 is fixed at the end of the device body 1 away from the hatch cover 5. Both the first hydraulic telescopic rods 14 and the second hydraulic telescopic rods 15 are installed and fixed inside the protective base 2. The filter assembly includes a filter screen mounting box 3 fixed in the middle of the device body 1. A sealing cap 4 is connected to the filter screen mounting box 3 by threaded clamps. A first filter screen 19 and a second filter screen 20 are sequentially arranged from the inside to the outside along the direction close to the device body 1. The inner wall of the main body 1 has multiple filter holes 18 evenly spaced along the circumference at the location corresponding to the filter assembly. A discharge port 10 is provided at the end of the filter screen mounting box 3 facing the protective base 2. The discharge port 10 is fixedly connected to the main body 1. A drain pipe 9 for discharging filtrate is also fixed on the filter screen mounting box 3. A heating pipe 11 is fitted above the wall cavity of the main body 1. The heating pipe 11 is used to regulate the material temperature inside the main body 1 to adapt to the dissolution and crystallization characteristics of calcium gluconate. A scraping part adapted to the inner wall of the main body 1 is provided at the end of the stirring rod 13 near the cover 5. When the stirring rod 13 extends or retracts to a position close to the inner wall of the main body 1, the scraping part can scrape off the filter cake remaining on the inner wall of the main body 1 as the stirring rod 13 rotates. An air pump 8 is fixedly installed on the cover 5.Air pump 8 is used to introduce air pressure into the main body 1 of the device to assist in the permeation of the spray washing liquid or the discharge and pushing of the filter cake. A sealing gasket is provided at the clamp connection between the cover 5 and the main body 1 of the device for introducing calcium gluconate crystal slurry into the device.

[0023] Working principle: The temperature inside the main body 1 is adjusted by the heating tube 11 to avoid crystal agglomeration or dissolution loss due to improper temperature. The calcium gluconate slurry to be processed is injected into the main body 1 through the feed hopper 6 on the side of the main body 1. The calcium gluconate slurry will fall into the slurry storage cavity formed by the support plate 12 and the top of the inner side of the main body 1. After reaching the specified amount, the first hydraulic telescopic rod 14 retracts, driving the support plate 12 to move down to the position of the filter hole 18. At the same time, a slight positive pressure is introduced into the device through the air pump 8. At this time, the second hydraulic telescopic rod 15 drives the stirring rod 13, which is fixedly connected to the output end of the first motor 16, to move down through the first motor 16. When the scraper part on the stirring rod 13 moves down... The liquid is attached to the clamp plate 12, and then the first motor 16 drives the stirring rod 13 to rotate and centrifuge the crystal slurry, pushing the liquid to penetrate into the filter assembly. The liquid passes through the filter holes 18 on the inner wall of the main body 1 and enters the filter screen installation box 3. It undergoes double-layer filtration by the first filter screen 19 to intercept large particles of impurities and the second filter screen 20 to retain small crystals, achieving solid-liquid separation. The filtered liquid is discharged through the drain pipe 9 on the filter screen installation box 3 and collected to the subsequent processing equipment. The solid calcium gluconate forms a uniform filter cake layer on the surface of the filter assembly. If the filter cake forms too quickly and causes blockage, the stirring rod 13 can be rotated and moved up and down to slightly disperse the surface of the filter cake to avoid the filter cake from being compacted and affecting the filtration rate. During washing, the washing liquid is pre-injected into the storage tank 27 next to the conical protective cover 17. At this time, the second hydraulic telescopic rod 15 drives the stirring rod 13 to move upward to below the washing liquid spraying plate 26 via the first motor 16. The first hydraulic telescopic rod 14 drives the support plate 12 to move upward. The upward-moving support plate 12 pushes the filter cake formed in the filter hole 18 area upward. At the same time, the support plate 12 scrapes the filter residue near the filter hole 18. When the support plate 12 moves above the filter hole 18, the second motor 22 is started, driving the rocker plate 23 to swing around the hanging rod 7, driving the infusion pipe 24 and the washing liquid spraying plate 26 to move synchronously. Since the guide ball 25 and the conical protective cover 17 are engaged by the ball bearing rotation, the washing liquid spraying plate 26 can achieve multi-directional swing, ensuring that the washing liquid covers the filter cake surface without blind spots. The first motor 16 is started to drive the stirring rod 13 to rotate, so that the stirring rod 13 stirs the filter cake. The leaf penetrates deep into the filter cake layer. During the stirring process, the filter cake is broken up, and the washing liquid fully penetrates into the interior of the filter cake, dissolving the residual mother liquor and impurities. After washing, the first hydraulic telescopic rod 14 retracts, driving the support plate 12 to move down to the position of the filter hole 18. At the same time, a slight positive pressure is introduced into the device through the air pump 8. At this time, the second hydraulic telescopic rod 15 drives the stirring rod 13, which is fixedly connected to the output end of the first motor 16, to move down. When the scraping part on the stirring rod 13 moves down and gets stuck on the support plate 12, the first motor 16 drives the stirring rod 13 to rotate and centrifugally stir the crystal slurry to assist the positive pressure, pushing the waste liquid after washing to be discharged. The waste liquid is filtered by the filter assembly and discharged from the drain pipe 9, and collected separately from the previous filtrate. By monitoring the conductivity of the waste liquid discharged from the drain pipe 9, when the conductivity is close to the conductivity of the washing liquid, it is determined that the filter cake washing meets the standard, and spraying and stirring are stopped. After washing, when the first hydraulic telescopic rod 14 retracts, it moves the support plate 12 down to the discharge port 10, causing the filter cake to move synchronously to the discharge port 10. Then, the second hydraulic telescopic rod 15 retracts, driving the stirring rod 13 down via the first motor 16. When the scraping part of the stirring rod 13 engages with the support plate 12, the first motor 16 is activated, driving the stirring rod 13 to rotate. The scraping part rotates with the stirring rod 13, pushing the filter cake on the inner wall of the device body 1 and the support plate 12 towards the discharge port 10. The filter cake passes through the discharge port 10. After the filter cake on the support plate 12 is discharged, the second hydraulic telescopic rod 15 drives the stirring rod 13 to move up and down in a cycle through the first motor 16. During the movement, the first motor 16 drives the stirring rod 13 to rotate and scrape the filter residue remaining on the inner wall of the main body 1. The scraped filter residue will fall onto the support plate 12 under the action of gravity. The filter residue flows towards the discharge port 10 through the support plate 12 and is discharged through the discharge port 10 and collected into the finished product storage equipment, thus completing the rapid separation of the calcium gluconate product.

[0024] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
