Description

Technical Field

[0001] This utility model relates to the field of enzyme storage technology, specifically to an environmentally friendly enzyme automatic degassing storage tank. Background Technology

[0002] An eco-enzyme storage tank is a device specifically designed to store eco-enzymes produced by the fermentation of organic matter. Eco-enzymes are typically made by fermenting fruit and vegetable residues with sugars, fermenting agents, and other substances. They possess environmentally friendly properties such as cleaning, decontamination, deodorization, and sterilization. When storing these enzymes, it is necessary to control the air pressure and temperature during the storage process to ensure the quality and safety of the enzymes. Taking an eco-enzyme automatic degassing storage tank disclosed in patent CN208703550U as an example, the enzyme fermentation liquid usually contains viscous organic matter (such as pectin and polysaccharides), which easily adheres to the inner wall of the vent pipe when depressurized. After the residue oxidizes, it forms a biofilm, which not only breeds miscellaneous bacteria and contaminates the enzymes in the tank, but also causes blockage of the exhaust channel. The mainstream solution in the market requires disassembling the exhaust components for manual cleaning, which is time-consuming and frequent disassembly accelerates the aging of the seals. More seriously, open cleaning introduces environmental microorganisms, increasing the risk of secondary pollution. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, this utility model provides an environmentally friendly automatic degassing storage tank for enzymes, which can effectively solve the problem that the enzyme fermentation liquid contains viscous organic matter that easily clogs the degassing hole.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an environmentally friendly enzyme automatic degassing storage tank, comprising: The tank body, with a tank cover threadedly installed at the upper end of the tank body; The cleaning and exhaust assembly includes a fixed tube threaded into the tank cover, a top plate fixedly installed on the inner wall of the fixed tube at a position away from the tank body, an exhaust port opened in the top plate, a conical head provided below the top plate, and multiple scrapers fixedly installed in a circumferential array on the upper end face of the conical head. The conical head and scrapers are driven to rise and slide to connect with the inner wall of the exhaust port to clean the residue adhering to the inner wall of the exhaust port.

[0005] Preferably, a lifting plate is slidably installed on the inner wall of the fixed tube and below the top plate. A threaded rod is rotatably installed on the upper end face of the lifting plate. A fixing plate is fixedly installed on the upper end face of the threaded rod. The upper end face of the fixing plate is fixedly connected to the conical head. An outer ring is fixedly installed on the outer wall of the conical head. Multiple limiting rods are fixedly installed in a circumferential array on the upper end face of the outer ring.

[0006] Preferably, a cross is fixedly installed on the inner wall of the fixed tube between the top plate and the lifting plate, a first spring is fixedly installed between the cross and the lifting plate, a sealing sheet is slidably embedded on the upper end face of the top plate at the position corresponding to the air outlet, a plurality of sliding rods are fixedly installed in a circumferential array on the lower end face of the sealing sheet, the lower end of the sliding rods penetrates the top plate and extends downward, a sliding sleeve is fixedly installed on the lower end face of the top plate, the sliding rods are slidably connected to the inner wall of the sliding sleeve, and a second spring is fixedly installed between the sliding rods and the sliding sleeve.

[0007] Preferably, a one-way bearing is rotatably mounted on the upper end face of the cross, and a threaded sleeve is fixedly mounted on the upper end face of the one-way bearing, with the inner wall of the threaded sleeve being threadedly connected to the threaded rod.

[0008] Preferably, a pressure monitoring element is fixedly installed below the can lid, the pressure monitoring element is electrically connected to a controller, and multiple electromagnets are embedded in a circumferential array at the lower end of the fixed tube. The electromagnets are electrically connected to the controller and magnetically attracted to the lifting plate.

[0009] Preferably, it further includes a connecting component, which includes a plurality of air inlets arranged in a circumferential array on the outer wall of the fixed tube, a slide rail fixedly installed on the inner wall of the fixed tube at the position corresponding to the air inlet, a sealing slider slidably installed on the inner wall of the slide rail, a top block fixedly installed on the upper end face of the lifting plate at the position corresponding to the sealing slider, a third spring fixedly installed between the sealing slider and the slide rail, and the sealing slider being airtightly slidably connected to the inner wall of the fixed tube.

[0010] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. By installing an automatically rising and rotating scraper at the venting channel, enzyme residues (sticky residues formed by pectin, polysaccharides, etc.) adhering to the inner wall of the channel can be scraped off simultaneously during the depressurization process. This fundamentally avoids the blockage caused by the oxidation of residues to form a biofilm and the resulting contamination of the enzymes in the tank by miscellaneous bacteria. At the same time, the flushing effect of the depressurization airflow can clean the scraper in the reverse direction, forming a self-maintenance mechanism, which significantly improves the reliability of the equipment and the hygiene and safety of enzyme storage. 2. Pressure monitoring and electromagnetic control (pressure monitoring element, controller, electromagnet) automatically triggers the cleaning and venting action when the internal pressure reaches a preset threshold. This process eliminates the need for manual disassembly of the venting components, simplifying operation, saving maintenance time, and, more importantly, avoiding the risk of accelerated aging of seals due to frequent disassembly and assembly. It also completely eliminates the possibility of secondary contamination caused by environmental microorganisms introduced during open cleaning, ensuring the stability of enzyme quality and a sterile environment during storage.

[0014] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] Example: Refer to Figures 1 to 5 An environmentally friendly enzyme automatic degassing storage tank, comprising: Tank body 1, with a tank cover 101 threaded onto the upper end of tank body 1; The cleaning and venting assembly 2 includes a fixed pipe 201 threadedly installed inside the tank cover 101. A top plate 203 is fixedly installed on the inner wall of the fixed pipe 201 at a position away from the tank body 1. An air outlet 217 is opened in the top plate 203. A conical head 208 is arranged below the top plate 203. Multiple scrapers 211 are fixedly arranged in a circumferential array on the upper end face of the conical head 208. The conical head 208 and the scrapers 211 are driven to rise and slide to connect with the inner wall of the air outlet 217 to clean the vent. As the scraper bar 211 rotates and rises to scrape away the residue adhering to the inner wall of the air outlet 217, the pressure relief airflow is simultaneously ejected at high speed from the air outlet 217. The airflow and the rotating scraper bar 211 form a vortex effect, which not only accelerates the peeling off of sticky residues (such as pectin and polysaccharides) adhering to the surface of the scraper bar 211, but also instantly carries the scraped residue out of the pipe through the shear force of the airflow, achieving a dual cleaning of "scraping-flushing". This process does not require additional energy and uses the pressure relief kinetic energy to complete the self-cleaning, significantly reducing the maintenance frequency.

[0017] Reference Figures 2 to 4 A lifting plate 204 is slidably installed on the inner wall of the fixed pipe 201 and below the top plate 203. A threaded rod 205 is rotatably installed on the upper end face of the lifting plate 204. A fixing plate 207 is fixedly installed on the upper end face of the threaded rod 205. The upper end face of the fixing plate 207 is fixedly connected to the conical head 208. An outer ring 209 is fixedly installed on the outer wall of the conical head 208. Multiple limit rods 210 are fixedly installed in a circumferential array on the upper end face of the outer ring 209. The lifting plate 204 has a built-in ferromagnetic material layer, which forms a uniform magnetic attraction surface with the electromagnets 216 in a ring array. The magnetic force disappears in less than 0.1 seconds after power failure. The threaded rod 205 and the threaded sleeve 219 are engaged by a swivel thread. With the help of a one-way bearing 218, the threaded sleeve 219 can only rotate in one direction. When the lifting plate 204 rises, the threaded engagement transmission occurs. When it falls, the threaded sleeve 219 idles, avoiding the risk of jamming.

[0018] Reference Figures 2 to 4 A cross 202 is fixedly installed on the inner wall of the fixed pipe 201 between the top plate 203 and the lifting plate 204. A first spring 206 is fixedly installed between the cross 202 and the lifting plate 204. A sealing plate 212 is slidably embedded on the upper end surface of the top plate 203 at the position corresponding to the air outlet 217. Multiple sliding rods 213 are fixedly installed in a circumferential array on the lower end surface of the sealing plate 212. The lower end of the sliding rod 213 passes through the top plate 203 and extends downward. A sliding sleeve 214 is fixedly installed on the lower end surface of the top plate 203. The sliding rod 213 is slidably connected to the inner wall of the sliding sleeve 214. A second spring 215 is fixedly installed between the sliding rod 213 and the sliding sleeve 214.

[0019] Reference Figures 2 to 4A one-way bearing 218 is rotatably mounted on the upper end face of the cross 202, and a threaded sleeve 219 is fixedly mounted on the upper end face of the one-way bearing 218. The inner wall of the threaded sleeve 219 is threadedly connected to the threaded rod 205.

[0020] Reference Figures 2 to 4 A pressure monitoring element is fixedly installed below the tank cover 101. The pressure monitoring element is an existing device, mainly used to detect and monitor gas pressure. It is widely used in equipment such as gas tanks, pipeline systems, and containers. Its main function is to measure and monitor changes in gas pressure in real time. The pressure monitoring element is electrically connected to a controller. Multiple electromagnets 216 are embedded in a circumferential array at the lower end of the fixed tube 201. The electromagnets 216 are electrically connected to the controller and magnetically attracted to the lifting plate 204. When the pressure monitoring element detects that the internal gas pressure of the tank 1 is lower than the preset value, the controller will re-control the voltage input to the electromagnet 216. The lifting plate 204, which has dropped due to the decrease in gas pressure, will re-magnetically engage with the electromagnet 216. The pressure monitoring element detects the gas pressure inside the tank in real time. When the pressure exceeds the preset threshold (e.g., 8–12 kPa), it triggers the controller. The controller uses a PID algorithm to dynamically adjust the on / off timing of the electromagnet 216 to ensure reliable operation within a gas pressure fluctuation range of ±1 kPa.

[0021] Reference Figure 5 It also includes a connecting component 3, which includes multiple air inlets arranged in a circumferential array on the outer wall of the fixed tube 201. A slide rail 302 is fixedly installed on the inner wall of the fixed tube 201 at the position corresponding to the air inlet. A sealing slider 303 is slidably installed on the inner wall of the slide rail 302. A top block 301 is fixedly installed on the upper end face of the lifting plate 204 at the position corresponding to the sealing slider 303. A third spring 304 is fixedly installed between the sealing slider 303 and the slide rail 302. The sealing slider 303 is airtightly slidably connected to the inner wall of the fixed tube 201.

[0022] The working principle of this utility model is as follows: The pressure monitoring element detects that the pressure inside the tank 1 has reached a preset value. The pressure monitoring element generates an electrical signal corresponding to the preset value. The controller controls the voltage input to the electromagnet 216 through the generated electrical signal, so that the electromagnet 216 no longer generates magnetic force and is attracted to the lifting plate 204. The pressure generated inside the tank 1 will push the lifting plate 204 to slide upward on the inner wall of the fixed tube 201 and compress the first spring 206. The driven lifting plate 204 will drive the threaded rod 205 to rise. The threaded rod 205 engages and rotates with the threaded sleeve 219 (the one-way bearing 218 restricts the rotation of the threaded sleeve 219 when the threaded rod 205 rises, allowing the threaded sleeve 219 to engage with the threaded rod 205; when the threaded rod 205 falls, the one-way bearing 218 drives the threaded sleeve 219 to rotate freely, and the threaded rod 205 no longer engages with the threaded sleeve 219 for transmission), driving the fixed plate 207. The conical head 208 and scraper 211 rotate and rise. During the rotation and rise of the scraper 211, it comes into rotational contact with the inner wall of the air outlet 217. The scraper 211 scrapes away the residue adhering to the inner wall of the air outlet 217, preventing residue from adhering to the inner wall of the air outlet 217 with the gas during the enzyme degassing process, which would lead to excessive accumulation and affect subsequent degassing. The continuously driven upward scraper 211 pushes the sealing plate 212 upward, causing the scraper 211 to drive the slide bar 213 in the sliding sleeve. The second spring 215 slides and pulls up inside 214, and a gap is generated between the sealing plate 212 and the top plate 203. During the process of the conical head 208 being driven to rise, the outer ring 209 and the limiting rod 210 will rise and contact the lower end face of the top plate 203. After the limiting rod 210 contacts the lower end face of the top plate 203, the gap between the limiting rods 210 allows the gas to flow, preventing the conical head 208 from blocking the air outlet 217 and facilitating the outward flow of gas. During the process of the lifting plate 204 being driven to rise, it will drive the top block 301 to rise together and contact the sealing slider 303. The sealing slider 303 will slide and rise in the slide rail 302 and compress the third spring 304, so that the air inlet is opened. The gas in the tank 1 enters the fixed pipe 201 through the air inlet and flows into the air outlet 217 through the gap between the limit rods 210. When the gas pressure is too high, the gas flow rate will increase. When it flows outward in the air outlet 217, it will blow away the residue scraped on the scraper 211, clean the scraper 211, and make it convenient for the next use.

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.
