Description

Technical Field

[0001] This utility model relates to the field of saccharifying enzyme treatment technology, and more specifically, it relates to a saccharifying enzyme ceramic membrane pulse purification device. Background Technology

[0002] In the field of bio-enzyme preparation production, saccharifying enzymes are a key industrial enzyme, and their purification process directly determines the enzyme activity retention rate and product purity. Among the mainstream saccharifying enzyme purification technologies in the industry, ceramic membrane filtration has become the core purification method due to its advantages of high temperature resistance, strong chemical stability, and high separation precision.

[0003] Traditional equipment often uses a constant pressure or constant flow rate filtration mode, which cannot effectively clean contaminants on the membrane surface and inside the membrane pores. As the filtration time increases, the membrane flux continues to decline, which not only reduces the purification efficiency of saccharifying enzymes, but also requires frequent shutdowns to disassemble the membrane modules for cleaning, seriously affecting the continuity of production.

[0004] While some devices are equipped with pulse backflush function, they mostly use pulse modes with fixed frequency and fixed intensity, which cannot dynamically adjust backflush parameters according to the degree of membrane fouling. When the filter cake layer on the membrane surface is thick or the membrane pores are severely blocked, the fixed intensity pulse is difficult to break through the pollutants and cannot effectively clean the membrane module, making the membrane module unusable. Utility Model Content

[0005] This invention provides a ceramic membrane pulse purification device for saccharifying enzymes, solving the problem that existing devices in related technologies have fixed pulse modes and cannot adapt to different levels of contamination. When the membrane surface is severely contaminated, fixed pulses are difficult to effectively penetrate the filter cake layer, resulting in incomplete cleaning, poor membrane flux recovery, and affecting continuous production and concentration efficiency.

[0006] This utility model provides a ceramic membrane pulse purification device for saccharifying enzymes, including a ceramic membrane purifier and a pulse mechanism installed on the ceramic membrane purifier. The pulse mechanism includes a mounting box, which is fixedly connected to the ceramic membrane purifier and connects an external gas supply device to the ceramic membrane purifier; a sliding plate, which is slidably installed inside the mounting box and connected to the mounting box by a first spring, with a first extrusion column fixedly installed on its top; and a first tilting block, which drives the first extrusion column to move the sliding plate downward, so that the pulse is sometimes strong and sometimes weak, and enters the membrane module through the downstream channel to backwash and clean the membrane module.

[0007] The optimized pulse mechanism includes: a first spring, one end of which is fixedly connected to the slide plate and the other end of which is fixedly connected to the mounting box; and a first tilting block, located above the slide plate and in contact with the first extrusion column.

[0008] The optimized pulse mechanism includes: a motor, fixedly mounted on the top of the mounting box, with a first rotating shaft fixedly mounted on its power output shaft; a second connecting pipe, fixedly connected to the first rotating shaft, with a third connecting pipe fixedly mounted at its bottom; a first connecting pipe, slidably mounted on the third connecting pipe and fixedly connected to the first inclined block, and connected to the third connecting pipe via a second spring; and a rotating pipe, rotatably mounted on the second connecting pipe.

[0009] The optimized pulse mechanism further includes: a fixed disk, fixedly mounted on the first rotating shaft, on which a drive rod is fixedly mounted; and a second rotating shaft, rotatably mounted on the mounting box, on which a drive disk is fixedly mounted.

[0010] The optimized version also includes a pressurizing mechanism, which comprises: a storage box, fixedly connected to the mounting box, on which a reciprocating lead screw fixedly connected to the second rotating shaft is rotatably mounted; a fourth connecting pipe, one end of which is fixedly connected to the storage box, and the other end of which is fixedly connected to the rotating pipe; and a threaded plate, which is slidably mounted on the storage box and threadedly connected to the reciprocating lead screw.

[0011] The optimized pressurizing mechanism includes: a second tilting block, which is slidably installed inside the storage box and slidably connected to the reciprocating lead screw; and a connecting plate, which is fixedly installed at the bottom of the second rotating shaft, on which a second extrusion column is fixedly installed.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a sliding plate and a first extrusion column driven by a motor and elastically connected to the mounting box by a first spring, enables the rotating first tilting block to periodically and non-fixed stroke extrude the first extrusion column, thereby driving the sliding plate to compress the air chamber and reciprocate under the restoring force of the first spring; it can continuously generate pulsed airflow with constantly changing intensity and frequency, effectively impacting the membrane surface, avoiding the adaptability of pollutants to a single mode of pulse, and improving the membrane fouling cleaning effect for the characteristics of saccharifying enzyme fermentation broth.

[0014] 2. This utility model transmits the rotational motion of the first rotating shaft in the pulse mechanism to the pressurizing mechanism through the fixed plate and the drive rod, drives the reciprocating screw to rotate, and then drives the threaded plate and the second inclined block to move linearly to synergistically squeeze the medium in the storage box; thereby further changing the gas pressure entering the ceramic membrane purifier, generating a higher intensity dynamic gas pulse, so that the membrane module can be further cleaned.

Detailed Implementation

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0024] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a ceramic membrane pulse purification device for saccharifying enzymes includes a ceramic membrane purifier 100 and a pulse mechanism 200 mounted on the ceramic membrane purifier 100. The pulse mechanism 200 includes a mounting box 201 fixedly connected to the ceramic membrane purifier 100, which connects an external gas supply device to the ceramic membrane purifier 100. A slide plate 205 is slidably mounted inside the mounting box 201, connected to the mounting box 201 via a first spring 206. A first extrusion column 204 is fixedly mounted on the top of the slide plate 205. A first tilting block 203 drives the first extrusion column 204 to move the slide plate 205 downwards, causing the pulse to be sometimes strong and sometimes weak, entering the membrane module through a downstream channel for backwashing and cleaning.

[0025] The downstream channel refers to the channel that connects the installation box 201 to the ceramic membrane purifier 100, allowing entry into the membrane module.

[0026] It should be noted that after the saccharifying enzyme fermentation broth undergoes pretreatment, it enters the ceramic membrane purifier 100 for purification. During the purification process, the pulse system in the ceramic membrane purifier 100 performs pulse cleaning on the membrane module. In this process, by continuously lowering the slide plate 205, the gas supplied by the external gas supply equipment to the installation box 201 is compressed into the ceramic membrane purifier 100, thus forming a strong pulse that better acts on the membrane module. Furthermore, the downward distance of the slide plate 205 is not fixed, resulting in different pulses. This allows the membrane module to be continuously acted upon by different pulses, improving the cleaning effect on the membrane module.

[0027] like Figures 2 to 4 As shown, the pulse mechanism 200 includes a mounting box 201, a first connecting pipe 202, a first tilting block 203, a first pressing column 204, a sliding plate 205, a first spring 206, a motor 207, a fixed plate 208, a drive rod 209, a rotating pipe 210, a second connecting pipe 211, a third connecting pipe 212, a first rotating shaft 213, a second rotating shaft 214, a drive plate 215, and a second spring 216.

[0028] One end of the first spring 206 is fixedly connected to the slide plate 205, and the other end of the first spring 206 is fixedly connected to the mounting box 201; the first tilting block 203 is located above the slide plate 205, and the first tilting block 203 is in contact with the first extrusion column 204.

[0029] The motor 207 is fixedly installed on the top of the mounting box 201, and a first rotating shaft 213 is fixedly installed on the power output shaft of the motor 207; the second connecting pipe 211 is fixedly connected to the first rotating shaft 213, and a third connecting pipe 212 is fixedly installed at the bottom of the second connecting pipe 211; the first connecting pipe 202 is slidably installed on the third connecting pipe 212, and the first connecting pipe 202 is fixedly connected to the first tilting block 203. The first connecting pipe 202 is connected to the third connecting pipe 212 through the second spring 216; the rotating pipe 210 is rotatably installed on the second connecting pipe 211.

[0030] It should be noted that when the motor 207 is started, the first rotating shaft 213 will rotate. The first rotating shaft 213 will cause the third connecting pipe 212 to rotate through the second connecting pipe 211. The third connecting pipe 212 will cause the first connecting pipe 202 to rotate, thereby causing the first tilting block 203 to rotate as well. Since the first tilting block 203 is tilted, it can continuously squeeze or release the first squeezing column 204 during rotation, causing the slide plate 205 to continuously compress or release the first spring 206 and move up and down. In this way, the slide plate 205 will continuously draw in or squeeze out the gas in the mounting box 201, causing the gas entering the ceramic membrane purifier 100 to change, changing the pulse pattern, making the pulse sometimes strong and sometimes weak, constantly changing dynamically, so that the pulse pressure acting on the membrane module constantly changes dynamically, thereby achieving a better cleaning effect on the membrane module.

[0031] like Figures 2 to 6 As shown, the fixed disk 208 is fixedly installed on the first rotating shaft 213, and the drive rod 209 is fixedly installed on the fixed disk 208; the second rotating shaft 214 is rotatably installed on the mounting box 201, and the drive disk 215 is fixedly installed on the second rotating shaft 214.

[0032] Storage box 302 is fixedly connected to mounting box 201. A reciprocating screw 303, which is fixedly connected to the second rotating shaft 214, is rotatably mounted on storage box 302. One end of the fourth connecting pipe 301 is fixedly connected to storage box 302, and the other end of the fourth connecting pipe 301 is fixedly connected to rotating pipe 210. Threaded plate 304 is slidably mounted on storage box 302 and threadedly connected to reciprocating screw 303.

[0033] The pressurizing mechanism 300 includes a fourth connecting pipe 301, a storage box 302, a reciprocating screw 303, a threaded plate 304, a second tilting block 305, a connecting disc 306, and a second extrusion column 307.

[0034] The second tilting block 305 is slidably installed inside the storage box 302, and the second tilting block 305 is slidably connected to the reciprocating lead screw 303; the connecting plate 306 is fixedly installed at the bottom of the second rotating shaft 214, and the second extrusion column 307 is fixedly installed on the connecting plate 306.

[0035] It should be noted that when the motor 207 causes the first rotating shaft 213 to rotate, it also causes the fixed disk 208 and the drive rod 209 to rotate. The rotation of the drive rod 209 causes the drive disk 215 to rotate intermittently. The rotation of the drive disk 215 causes the second rotating shaft 214 to rotate. The rotation of the second rotating shaft 214 causes the reciprocating lead screw 303 to rotate. The rotation of the reciprocating lead screw 303 causes the threaded plate 304 to move up and down. The up and down movement of the threaded plate 304 causes the gas in the storage box 302 to be discharged into the first connecting pipe 202 through the fourth connecting pipe 301, thereby causing the first connecting pipe 202 to move further down and squeeze the slide plate 20. 5. In this way, the slide plate 205 can further compress the gas in the mounting box 201, so that the gas forms a new pulse and acts on the membrane module in the ceramic membrane purifier 100. During the rotation of the reciprocating screw 303, the connecting plate 306 will cause the second extrusion column 307 to rotate, so that the second tilting block 305 will move up and down continuously. In this way, the threaded plate 304 and the second tilting block 305 will squeeze the gas in the storage box 302 against each other, which can further change the gas input, change the downward movement distance of the first connecting pipe 202, change the amount of gas compression of the slide plate 205 in the first connecting pipe 202, and change the effect of the pulse.

[0036] Working principle: Start motor 207, the power output shaft of motor 207 drives the first rotating shaft 213 to rotate, the first rotating shaft 213 synchronously drives the fixed disk 208 and the second connecting pipe 211 to rotate.

[0037] When the second connecting pipe 211 rotates, it drives the third connecting pipe 212 to rotate. The third connecting pipe 212 drives the first connecting pipe 202 to rotate. The first connecting pipe 212 and the third connecting pipe 212 are elastically engaged by the second spring 216. The first connecting pipe 202 drives the first tilting block 203 to rotate.

[0038] Because the first tilting block 203 is tilted, it continuously squeezes or releases the first squeezing column 204 located on top of the slide plate 205 during its rotation: when squeezing, it pushes the slide plate 205 downwards within the mounting box 201, compressing the first spring 206, and simultaneously compressing the gas input from the external gas supply equipment through the mounting box 201 and sending it into the ceramic membrane purifier 100, forming a strong pulse; when releasing, the first spring 206 resets, causing the slide plate 205 to move upwards, and the mounting box 201 to re-intake gas. During this process, the downward distance of the slide plate 205 is not fixed, causing the pulse entering the ceramic membrane purifier 100 to be sometimes strong and sometimes weak, entering the membrane module through the downstream channel to achieve dynamic backwashing and cleaning of the membrane module, preventing contaminants from adapting to a single pulse mode.

[0039] At the same time, the rotation of the fixed plate 208 drives the drive rod 209 to rotate, the drive rod 209 drives the drive plate 215 to rotate intermittently, and the drive plate 215 drives the second rotating shaft 214 to rotate on the mounting box 201; the rotating tube 210 rotates synchronously with the second connecting tube 211 to provide a channel for subsequent airflow convergence.

[0040] When the second rotating shaft 214 rotates, it drives the reciprocating screw 303 to rotate on the storage box 302. The reciprocating screw 303 drives the threaded plate 304 to slide up and down inside the storage box 302, and at the same time drives the second tilting block 305 to slide inside the storage box 302.

[0041] The rotation of the second rotating shaft 214 also drives the connecting plate 306 to rotate, and the connecting plate 306 drives the second extrusion column 307 to rotate. The second extrusion column 307 cooperates with the second tilting block 305 to assist in pushing the second tilting block 305 to slide, so that the threaded plate 304 and the second tilting block 305 jointly extrude the gas in the storage box 302.

[0042] The compressed gas in the storage box 302 is transported to the rotating tube 210 through the fourth connecting tube 301, and then enters the second connecting tube 211 through the rotating tube 210. After merging with the airflow generated by the pulse mechanism, it is sent into the ceramic membrane purifier 100 to further enhance the dynamic range of pulse intensity, improve the backwashing and cleaning effect on the membrane module, and effectively break through the thicker filter cake layer and block the membrane pores.

[0043] After pretreatment, the saccharifying enzyme fermentation broth enters a ceramic membrane purifier 100 for purification. The aforementioned dynamic pulse and pressurized airflow work synergistically to continuously backwash and clean the membrane module, preventing a decrease in membrane flux and ensuring purification efficiency and production continuity.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
