Description

Technical Field

[0001] The invention relates to the field of alcohol preparation, in particular to a filtering device for alcohol preparation. Background Art

[0002] Alcohol is a widely used chemical, widely used in chemical, pharmaceutical, food and other industries. Alcohol can be prepared by fermentation or chemical synthesis. The fermentation method is mainly used for brewing alcohol and producing fuel ethanol. The main processes of the fermentation method include raw material preparation, pretreatment (crushing), saccharification, fermentation, distillation, dehydration and other steps. In the process of alcohol preparation, filtration is an important link. In the pretreatment stage, the crushed raw materials need to be filtered to prevent large particles of raw materials produced by uneven crushing from entering the saccharification tank, which will weaken the saccharification effect of the enzyme and affect the completeness of subsequent fermentation. At the same time, it can also prevent the blockage of downstream equipment; in the saccharification process, it is necessary to filter out the undissolved solid particles that may be contained in the sugar solution to ensure that the sugar solution is as clear as possible to improve the purity of the sugar solution.

[0003] However, the following problems still exist in the process of filtering the crushed raw materials and the saccharified sugar solution: (1) A large amount of crushed raw materials are usually uniformly vibrated and filtered. A large amount of crushed raw materials are prone to accumulation and clogging during vibration filtration, resulting in reduced filtration quality and efficiency. In addition, it is difficult for the crushed raw materials to maintain good fluidity by a single vibration. At the same time, it takes time to remove the large particles of raw materials remaining after filtration, and the continuity of filtration is low.

[0004] (2) Generally, the saccharified sugar solution is directly filtered using a filter medium. After filtering a certain amount of sugar solution, the residue will accumulate on the filter medium, causing the filtering performance of the filter medium to fail to meet the filtering requirements. At the same time, after a long period of filtration, the filtering performance of a single filter medium will also decrease, and even the filtration will be oversaturated, resulting in a decrease in the filtering effect and efficiency of the subsequent sugar solution.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] See also Figure 1 , Figure 2 and Figure 3 The upper filtering unit 21 includes a square frame 211 installed on the upper end of the saccharification tank 2, a feeding frame 212 is installed on the upper end of the square frame 211, and the front and rear inner walls of the feeding frame 212 are both installed with material guide plates 213 inclined toward the center direction of the square frame 211, and the material guide plates 213 on the front and rear sides are staggered left and right, a horizontal plate 214 is installed between the left and right inner walls of the upper end of the square frame 211, a conical column 215 is rotatably installed in the middle of the horizontal plate 214, and partitions 216 are installed on the left and right sides of the conical column 215.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The bottom of the square frame 211 is provided with a filter assembly, which includes a filter screen 217 symmetrically arranged between the left and right inner walls of the square frame 211 and rotatably connected to the lower end of the conical column 215. An outlet is arranged between the front and rear filter screens 217, which is located on the left and right sides of the conical column 215 respectively. The left and right inner walls of the square frame 211 are provided with an opening groove for avoiding the movement of the filter screen 217. The left and right ends of the filter screen 217 on the side close to each other are slidably connected to the connecting column 218 installed between the upper and lower inner walls of the opening groove. A connecting spring sleeved on the outside of the connecting column 218 is connected between the upper end surface of the filter screen 217 and the top wall of the opening groove. The side of the filter screen 217 away from each other slides through the square frame 211. It should be noted that the filter screen 217 is a non-rigid structure with deformation ability.

[0036] See also Figure 2 , Figure 3 and Figure 5 A control component for controlling the synchronous up and down reciprocating movement of the filter screens 217 on the front and rear sides is provided at the lower end of the square frame 211. The control component includes three triangular baffles 231 evenly arranged on the left and right sides hinged on the lower end surface of the filter screen 217. A moving rod 232 is installed at the lower end of the triangular baffle 231. The lower end of the moving rod 232 is slidably connected to the outer ring surface of the cam 233. The states of the two cams 233 located on the front and rear sides below the same filter screen 217 are consistent and opposite to the state of the cam 233 located in the middle. The eccentric parts of the cams 233 below the two filter screens 217 are connected by the same rotating shaft 234, and the rotating shaft 234 is rotatably installed between the front and rear inner walls of the square frame 211. The rear end of the rotating shaft 234 rotates through the rear end of the square frame 211 and is connected to the output shaft of the motor 235 installed on the outer wall of the rear end of the square frame 211.

[0037] During operation: before the crushed raw materials enter the saccharification tank 2, the existing feeding pipeline continuously feeds the pre-treated crushed raw materials into the feed frame 212, and the crushed raw materials entering the feed frame 212 flow downward into the square frame 211 through the guide plates 213 on the front and rear sides, and the crushed raw materials flowing into the square frame 211 through the front guide plate 213 finally reach the upper end of the filter screen 217 on the rear side, and the crushed raw materials flowing into the square frame 211 through the rear guide plate 213 finally reach the filter screen 217 on the front side. At the upper end, the guide plates 213 on the front and rear sides can divert a large amount of crushed raw materials entering the feed frame 212 to avoid a large amount of crushed raw materials from being concentrated in a single filtering area. The conical column 215 and the horizontal plates 214 on its left and right sides can separate the crushed raw materials on the front and rear filter screens 217 to achieve regional filtration of the crushed raw materials. By filtering a large amount of crushed raw materials in different areas and quantities, it is possible to avoid excessive accumulation of crushed raw materials and clogging the filter screen 217, which is beneficial to improving the filtration efficiency.

[0038] In the initial state, the front and rear filter screens 217 are both in a horizontal state. While conveying the crushed raw materials, the motor 235 can be used to drive the rotating shaft 234 to rotate, and the rotating shaft 234 drives the cam 233 under the front and rear filter screens 217 to rotate synchronously. The cam 233 drives the triangular baffle 231 to move back and forth up and down through the cooperation between the cam 233 and the moving rod 232. The triangular baffle 231 can drive the filter screen 217 to move back and forth up and down. Since the states of the cams 233 under the same filter screen 217 and located on the front and rear sides are consistent and opposite to the state of the cam 233 located in the middle, when the cam 233 located in the middle pushes the moving rod 232 and the triangular baffle 231 to move upward, the cams 233 on the front and rear sides move the triangular baffle 231 downward to the initial state through the moving rod 232, so as to realize the reciprocating up and down fluctuation of the filter screen 217, and the filter screens 217 on the front and rear sides reciprocate up and down synchronously, and the triangular baffle 231 hinged to the lower end surface of the filter screen 217 The filter 217 can rotate with the fluctuation of the filter screen 217 to avoid the moving rod 232 and the cam 233 from blocking the crushed raw materials when passing through the filter screen 217 and entering the saccharification tank 2. During this process, the filter screen 217 close to the side of the conical column 215 is deformed synchronously and fluctuates up and down along the connecting column 218 and the opening groove under the action of the connecting spring. The filter screen 217 can be quickly reset after deformation through the cooperation of the connecting spring and the connecting column 218. At the same time, the side of the filter screen 217 away from the conical column 215 can slide back and forth along the square frame 211 accordingly to ensure that the filter screen 217 can fluctuate up and down smoothly. The crushed raw materials are dynamically filtered by using the fluctuating filter screen 217, which can not only enhance the fluidity of the crushed raw materials, ensure that the crushed raw materials are effectively dispersed on the filter screen 217, improve the filtering quality and filtering efficiency, but also avoid the accumulation of particulate matter in the crushed raw materials and block the filter screen 217, thereby affecting the effectiveness of filtering.

[0039] See also Figure 2 , Figure 3 and Figure 4The partition 216 is provided with a square groove inside, and an extension plate 236 is installed inside the square groove for sliding left and right. A telescopic spring 237 evenly arranged up and down is connected between the extension plate 236 and the side wall of the square groove. An elastic telescopic rod 238 evenly arranged left and right is installed at the lower end of the extension plate 236. A brush 239 is installed at the lower end of the telescopic end of the elastic telescopic rod 238. The brush 239 evenly arranged left and right is installed at the lower end of the partition 216. The left end of the square frame 211 is provided with a brush for driving the cone The rotating assembly for rotating the conical column 215 and the partition plate 216 includes a connecting pulley 241. The upper end of the conical column 215 rotates and passes through the horizontal plate 214 and is fixedly connected to the connecting pulley 241. The left end of the square frame 211 is rotatably installed with a transmission pulley 242. The transmission pulley 242 and the connecting pulley 241 are connected by a belt that slides through the left end of the square frame 211. The lower end surface of the transmission pulley 242 is connected to the output shaft of a motor 243 installed on the outer wall of the left end of the square frame 211.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 , the upper ends of the outlets on the left and right sides are both provided with triangular prisms, a rectangular plate 245 is connected between the lower ends of the left and right triangular prisms, a moving assembly for controlling the up and down movement of the rectangular plate 245 is provided at the lower end of the conical column 215, the moving assembly includes a threaded column 246 installed in the middle of the lower end of the conical column 215 and threadedly connected to the rectangular plate 245, and guide columns 247 connected to the triangular prism and the rectangular plate 245 for sliding up and down are installed between the upper and lower inner walls of the left and right opening grooves, and a guide frame 248 located below the rectangular plate 245 and inclined to the lower right and passing through the square frame 211 is provided between the lower parts of the left and right outlets, the guide frame 248 is located above the rotating shaft 234, and side panels inclined in the direction of the rectangular plate 245 and located inside the square frame 211 are symmetrically installed on the upper end face of the guide frame 248, the threaded column 246 is located inside the guide frame 248, a square support plate is installed on the right side of the saccharification tank 2, and a receiving frame 251 is provided on the upper end of the square support plate.

[0041] During operation: the crushed raw materials after dynamic filtration can pass through the filter screen 217 and enter the saccharification tank 2, and the large particles of the crushed raw materials are retained at the upper end of the filter screen 217. At this time, the filter screen 217 is in an initial state, and then the transmission pulley 242 can be driven to rotate by the motor 243. The transmission pulley 242 drives the connecting pulley 241 and the conical column 215 to rotate synchronously through the belt. In the initial state, the outlets on the left and right sides cooperate with the corresponding triangular prisms and are in a closed state. When the conical column 215 rotates, it drives the threaded column 246 at its lower end to rotate synchronously. The rectangular plate 245 drives the triangular prism to move downward along the guide columns 247 on the left and right sides to the guide frame 248 as the threaded column 246 rotates, so that the outlets on the left and right sides are in an open state.

[0042] During the rotation of the conical column 215, the partitions 216 and the extension plates 236 on the left and right sides rotate synchronously. The partitions 216 drive the evenly distributed brushes 239, and the extension plates 236 drive the elastic telescopic rods 238 and the corresponding brushes 239 to rotate synchronously. The filtered large particles of raw materials can be pushed toward the direction of the outlet through the rotating partitions 216, the extension plates 236 and the brushes 239. The extension plate 236 is in a compressed state in the initial state. As the partition 216 rotates, the extension plate 236 can automatically retract and retract under the action of the rebound force of the telescopic spring 237. The extension plate 236 is always in contact with the inner wall of the square groove, so that the extension plate 236 can drive the brush 239 to fully and effectively move the large particles of raw materials on the filter screen 217. The brush 239 can not only move the large particles of raw materials remaining on the filter screen 217 to the inside of the outlet, thereby increasing the discharge speed of the large particles of raw materials, but also dredge and clean the filter screen 217 to prevent the crushed raw materials from being blocked on the filter screen 217, thereby ensuring the permeability of the filter screen 217 and improving the filtering quality of the filter screen 217. After the large particles of raw materials are discharged from the filter screen 217, the motor 243 is used to rotate and reset the conical column 215 and the partitions 216 on the left and right sides to the initial state, and the triangular prism and the rectangular plate 245 are synchronously moved up and reset to close the outlet again, so as to filter the subsequent crushed raw materials in different areas. Even when the filter 217 is not in a straight state when removing large particles of raw materials, the elastic telescopic rod 238 at the lower end of the extension plate 236 can also be adaptively telescopically adjusted according to the shape of the filter 217 to ensure that the brush 239 clears the filter 217 and moves the large particles of raw materials.

[0043] After the large-particle raw materials entering the outlet enter the guide frame 248, they can flow along the inclined guide frame 248 to the collection frame 251. The collection frame 251 can collect the remaining large-particle raw materials, which can be recycled later to increase the utilization rate of the crushed raw materials.

The upper end of the diatomaceous earth filter disc 222 is provided with two filtering grooves 223 symmetrical about its central axis. The right end of the fixed base 1 is provided with a driving assembly for driving the four diatomaceous earth filter discs 222 to rotate synchronously.

[0046] See also Figure 1 , Figure 6 , Figure 7 and Fig.10 A push plate is installed at one end of the movable plate 258 away from the arc-shaped baffle plate 252, and a slide groove is opened at the side end of the push plate. A slider connected to the slide groove for sliding up and down is installed at the telescopic end of the electric push rod 261, and a control spring is connected between the slider and the slide groove wall. The position corresponding to the arc-shaped mounting plate 255 on the fixed cylinder 221 is opened with an arc-shaped through groove for avoiding the arc-shaped mounting plate 255. An arc block 262 matching the arc-shaped through groove is installed on the telescopic end of the electric push rod 261. The electric push rod 261 is installed on the outside of the fixed cylinder 221 through a bracket, and a downward-inclined guide plate 263 is installed at the lower end of the position of the arc-shaped through groove on the outside of the fixed cylinder 221. A receiving plate fixedly connected to the outer wall of the fixed cylinder 221 is arranged below the guide plate 263, and a collection frame 264 is arranged at the upper end of the receiving plate.

[0047] During operation: after the crushed raw materials fall into the saccharification tank 2, the saccharification tank 2 performs saccharification treatment on the crushed raw materials. After a period of time, the saccharified sugar liquid can flow to the inside of the fixed cylinder 221 through the conveying pipe. Since the four diatomaceous earth filter disks 222 are evenly distributed in the circumference and staggered up and down, the sugar liquid entering the fixed cylinder 221 is diverted to the corresponding filter grooves 223 on the four diatomaceous earth filter disks 222 for filtering treatment, and the filtered sugar liquid flows downward. During this process, the arc baffle 252 can guide the sugar liquid flowing into the diatomaceous earth filter disk 222 to ensure that the sugar liquid can smoothly flow into the corresponding filter groove 223. The diatomaceous earth filter disks 222 staggered up and down can be used to divert the sugar liquid for multi-stage filtration. Under the condition of ensuring that the silicon sugar liquid is effectively filtered, the saturation of the single diatomaceous earth filter disk 222 is avoided. The filtered sugar liquid will flow into the subsequent fermentation pipeline along the fixed cylinder 221, and the filtered residue will remain in the filter groove 223.

[0048] In order to ensure that the diatomaceous earth filter disc 222 always maintains good filtering performance, the residue inside the filter groove 223 can be cleaned. In this process, the motor 3 229 can be used to drive the external pulley to rotate, and the control pulley 228 can be controlled to rotate synchronously with the external pulley through the belt 2. When the control pulley 228 rotates, the corresponding rotating gear 225 and the rotating rod 224 can be driven to rotate synchronously with the diatomaceous earth filter disc 222. The rotating gear 225 on the right side drives the inner gear ring 226 to rotate synchronously along the inner wall of the annular conical sleeve plate 227. The remaining rotating gears 225 drive the corresponding rotating rods 224 and the diatomaceous earth filter disc 222 to rotate synchronously with the rotation of the inner gear ring 226. The disk 222 rotates synchronously until the used filter groove 223 on the diatomaceous earth filter disk 222 rotates to the side close to the inner wall of the fixed cylinder 221, and the residue after the sugar solution is filtered rotates synchronously therewith, and the unused filter groove 223 rotates to the corresponding filtering position to realize the replacement of the filtering position of the diatomaceous earth filter disk 222, thereby ensuring the effectiveness of the filtration of the diatomaceous earth filter disk 222. In the process of the sugar solution flowing to the subsequent fermentation pipeline, the circular ring plate, the annular conical sleeve plate 227 and the protective sleeve plate can protect the rotating gear 225, the inner gear ring 226, the control pulley 228 and the belt 2, and can ensure the smoothness of the sugar solution flow.

[0049] In the initial state, the scraping members are all located inside the fixed cylinder 221 and close to the corresponding arc-shaped baffle 252, and the arc-shaped mounting plate 255 and the inclined scraper 256 are both located above the corresponding diatomaceous earth filter disc 222. After the replacement of the filtering position on the diatomaceous earth filter disc 222 is completed, the circumferentially distributed electric push rod 261 can simultaneously drive the corresponding push plate, the movable plate 258 and the arc-shaped mounting plate 255 to move outward along the upper side of the corresponding diatomaceous earth filter disc 222. The inclined scraper 256 is in a natural extension state under the action of the adjusting spring 257 at the initial stage and does not contact the upper end surface of the diatomaceous earth filter disc 222. In the process that the arc-shaped mounting plate 255 drives the adjusting spring 257 and the inclined scraper 256 to move outward, the movable plate 258 slides synchronously along the corresponding sliding groove 259. Since the arc-shaped protrusion has the same curvature as the filtering groove 223, the arc-shaped protrusion is in a state of natural extension under the action of the adjusting spring 257. In the process that the arc-shaped mounting plate 255 drives the evenly arranged inclined scrapers 256 to move outward along the corresponding filter groove 223, the inclined scraper 256 located in the middle of the arc-shaped mounting plate 255 can first enter the corresponding filter groove 223 with the movement of the arc-shaped mounting plate 255, while the remaining inclined scrapers 256 slide upward along the inclined groove through the compression adjustment spring 257 and are in a compressed state. In the process that the moving plate 258 slides along the sliding groove 259, the push plate moves up and down along the slider by controlling the cooperation between the spring and the slide groove, so that the moving plate 258 drives the arc-shaped mounting plate 255 to move smoothly. As the arc-shaped mounting plate 255 continues to move outward, the remaining inclined scrapers 256 gradually stretch naturally and enter the filter groove 223. The evenly arranged inclined scrapers 256 can be used to scrape off the residue inside the corresponding filter groove 223 and scrape the residue outward.

[0050] During the movement of the telescopic end of the electric push rod 261, the corresponding arc block 262 moves synchronously and opens the arc slot. When the moving plate 258 drives the arc mounting plate 255 and the inclined scraper 256 to continue to move outward along the support plate 253, the arc mounting plate 255 and the inclined scraper 256 can gradually push the residue from the inside to the outside through the arc slot and finally make the residue enter the guide plate 263. In this process, the connecting plate 254 can support the residue moved from the diatomaceous earth filter plate 222 to the arc slot to prevent the residue from The residue flows along the gap between the diatomaceous earth filter disc 222 and the inner wall of the fixed cylinder 221 to the inside of the fermentation pipe below, and the residue on the guide plate 263 can flow downward to the inside of the corresponding collecting frame 264. The filtered residue can be uniformly collected by the collecting frame 264 so that the residue can be subsequently processed accordingly. Cleaning the filter groove 223 is helpful to improve the cleanliness of the diatomaceous earth filter disc 222, ensuring that the diatomaceous earth filter disc 222 maintains good filtering performance, thereby improving the filtering effect of the sugar solution, and then improving the filtering efficiency of the sugar solution.

[0051] After the filter grooves 223 on different diatomaceous earth filter discs 222 are cleaned at the same time, the electric push rod 261 can drive the arc block 262, the push plate, the movable plate 258, the arc mounting plate 255, and the inclined scraper 256 to move inward and reset along the support plate 253. At this time, the arc block 262 can cooperate with the arc through groove again, so that the fixed cylinder 221 is in a closed state, and the scraper is reset to a position close to the arc baffle 252. Subsequently, the sugar solution can be filtered and the filter grooves 223 can be cleaned after use in the same way.
