Description

Technical Field

[0001] This utility model belongs to the field of filtration technology for sucralose decolorization, specifically a filtration device for sucralose production. Background Technology

[0002] During the production of sucralose, activated carbon is used for decolorization. After decolorization, the activated carbon in the sucralose solution needs to be filtered.

[0003] In the filtration of sucralose, the activated carbon mainly consists of large pieces of activated carbon and granular carbon powder that falls off the large pieces of activated carbon. Existing filtration devices only filter the large pieces of activated carbon using a filter screen, while the spring remains in the sucralose solution, thus affecting the purity of the sucralose. Utility Model Content

[0004] This invention provides a filtration device for sucralose production to address the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A filtration device for sucralose production includes a vertically arranged coarse filter pipe and a fine filter pipe, which are connected by a horizontal pipe and the fine filter pipe is detachably connected to the horizontal pipe. The lower end of the coarse filter pipe is closed and the upper part is connected to a filter screen. The lower end of the fine filter pipe is closed by a baffle plate with several water outlet holes. The top surface of the baffle plate is covered with filter cloth. Above the fine filter pipe, a pressure plate adapted to the inner diameter of the suction filter pipe and positioned above the horizontal pipe is provided. The pressure plate is driven by a driving device to move up and down along the suction filter pipe.

[0007] In use, the decolorized sucralose solution is poured into a coarse filter tube, where large pieces of activated carbon are filtered by the filter screen, while small particles of activated carbon or activated carbon powder enter the fine filter tube through the coarse filter tube and the horizontal tube. The small particles of activated carbon or activated carbon powder are blocked by the filter cloth. Due to the small diameter of the filter cloth, it is difficult for the sucralose solution to drain during filtration. At this point, a driving device presses down on the pressure plate, which squeezes the cavity between the filter cloth and the pressure plate, allowing the sucralose solution to be quickly squeezed out. After the solution is squeezed out, the large pieces of activated carbon in the filter screen are removed, and the fine filter tube is disassembled to pour out the activated carbon powder, thus filtering the activated carbon powder and ensuring that there is no carbon powder in the sucralose solution, thereby improving the purity of sucralose.

[0008] Preferably, the fine filter tube is threaded into the outer tube, the horizontal tube is perpendicularly connected to and communicates with the outer tube, and the drive device is located inside the outer tube. The sucralose solution enters the outer tube through the horizontal tube and then enters the fine filter tube through the outer tube. The threaded connection between the fine filter tube and the outer tube facilitates the disassembly of the fine filter tube.

[0009] Preferably, a support ring is fixedly provided circumferentially along the inner diameter of the coarse filter tube, and a filter screen is placed on the support ring. The filter screen has a circular structure and its diameter is the same as the inner diameter of the coarse filter tube. A pull rod that extends out of the coarse filter tube is vertically connected to the filter screen. The support ring provides support for the filter screen, while the pull rod allows the filter screen to be pulled out by pulling the rod upwards when the activated carbon is removed.

[0010] Preferably, the driving device is an electric telescopic rod. The fixed end of the electric telescopic rod is fixedly mounted on the outer tube, and the movable end of the electric telescopic rod is perpendicularly connected to the pressure plate. When the electric telescopic rod is retracted to its shortest length, the pressure plate is located above the horizontal tube. The extension of the electric telescopic rod can drive the pressure plate to move downward, thereby achieving the squeezing and filtration of the sucralose solution.

[0011] Preferably, the movable rod of the electric telescopic rod has a groove extending upwards along its axis, and an inner rod slides within the groove. The top surface of the inner rod is fixedly connected to the inner wall of the groove top surface by a spring, and the inner rod is fixedly connected to the pressure plate. A spring is provided between the inner rod and the movable rod of the electric telescopic rod, which acts as a buffer when the pressure plate presses down on the sucralose solution, achieving better compression of the sucralose solution.

[0012] Preferably, the inner wall of the bottom surface of the coarse filter tube is fixedly provided with a slope, the slope of which slopes downwards towards the horizontal tube. The slope acts as a guide, allowing the sucralose solution to flow better into the horizontal tube.

[0013] The beneficial effects of this utility model are as follows: The use of this application can achieve secondary filtration of sucralose solution by using a filter screen and filter cloth, thereby avoiding the presence of carbon powder in the sucralose solution and ensuring the purity of the sucralose solution. At the same time, the pressure plate can be used to squeeze the sucralose solution, so that the filtration speed is faster when filtering at the filter cloth. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A filtration device for sucralose production, such as Figure 1 and Figure 2 As shown. It includes a vertically arranged coarse filter pipe 1, a fine filter pipe 4, and an outer pipe 3. The outer pipe is supported and fixed by a bracket. The fine filter pipe is threadedly connected to the lower end of the outer pipe 3. The coarse filter pipe 1 and the outer pipe 3 are connected by a horizontal pipe 2. The lower end of the coarse filter pipe 1 is closed and the upper part is connected to a filter screen 5. The lower end of the fine filter pipe 4 is closed by a baffle with several water outlet holes. The top surface of the baffle is covered with filter cloth 6. Above the fine filter pipe 4, there is a pressure plate 9 that matches the inner diameter of the suction filter pipe and can move up and down along the suction filter pipe by a driving device. Below the baffle, there is a horizontally lying receiving bucket with its opening facing upward.

[0021] In use, the decolorized sucralose solution is poured into the coarse filter tube 1, where large pieces of activated carbon are filtered by the filter screen 5, while small particles of activated carbon or activated carbon powder enter the fine filter tube 4 through the coarse filter tube 1, the horizontal tube 2, and the outer tube 3. The small particles of activated carbon or activated carbon powder are blocked by the filter cloth 6. Due to the small diameter of the filter cloth 6, it is difficult for the sucralose solution to drain during filtration. At this point, a driving device presses down on the pressure plate 9, which squeezes the cavity between the filter cloth 6 and the pressure plate 9, allowing the sucralose solution to be quickly squeezed out. The squeezed solution enters the receiving tank. After the solution is squeezed out, the large pieces of activated carbon in the filter screen 5 are removed, and the fine filter tube 4 is disassembled to pour out the activated carbon powder, thus filtering the activated carbon powder and ensuring that there is no carbon powder in the sucralose solution, thereby improving the purity of sucralose.

[0022] The fine filter tube 4 is threadedly connected to the outer tube 3, which facilitates the disassembly of the fine filter tube 4.

[0023] The upper part of the coarse filter tube 1 extends upward with a flared opening that is wider at the top and narrower at the bottom, which makes it easy to pour the sucralose solution into the coarse filter tube 1.

[0024] A support ring 7 is fixedly installed circumferentially along the inner diameter of the coarse filter tube 1. A filter screen 5 is placed on the support ring 7. The filter screen 5 has a circular structure and its diameter is the same as the inner diameter of the coarse filter tube 1. A pull rod 12 that extends out of the coarse filter tube 1 is vertically connected to the filter screen 5. The support ring 7 provides support for the filter screen 5, while the pull rod 12 can be used to pull the filter screen 5 out when the activated carbon is removed.

[0025] The driving device is an electric telescopic rod 8. The fixed end of the electric telescopic rod 8 is fixedly mounted on the outer tube 3. When the electric telescopic rod 8 is retracted to its shortest length, the pressure plate 9 is located above the horizontal tube 2. The movable rod of the electric telescopic rod 8 has a groove 10 extending upward along its axis. An inner rod 11 is slidably fitted inside the groove 10. The top surface of the inner rod 11 is fixedly connected to the inner wall of the top surface of the groove 10 by a spring. The inner rod 11 is also fixedly connected to the pressure plate 9. The extension of the electric telescopic rod 8 can drive the pressure plate 9 to move downward, thereby achieving the compression and filtration of the sucralose solution. A spring 14 is provided between the inner rod 11 and the movable rod of the electric telescopic rod 8. When the pressure plate 9 presses down on the sucralose solution, the spring 14 acts as a buffer, achieving better compression of the sucralose solution.

[0026] The bottom inner wall of the coarse filter tube 1 is fixedly provided with a ramp 13, the slope of which slopes downward toward the horizontal tube 2. The ramp 13 serves as a guide, allowing the sucralose solution to flow better into the horizontal tube 2.

[0027] The use of this application enables secondary filtration of sucralose solution using filter screen 5 and filter cloth 6, thereby avoiding the presence of carbon powder in the sucralose solution and ensuring the purity of the sucralose solution. At the same time, the pressure plate 9 can be used to squeeze the sucralose solution, resulting in a faster filtration speed when filtering at the filter cloth 6.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
