Description

Technical Field

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

[0002] During ethanol production, various impurities may be introduced from raw materials and the reaction process, such as suspended solids, precipitates, and unreacted raw material components. Filtration can effectively remove these impurities, improve the purity of ethanol, and facilitate the reuse of wastewater ethanol. Filtration is an important means of removing residual impurities and helps to obtain a purer ethanol product. Filtration during ethanol production is an important means of improving purity, quality, production efficiency, and ensuring product safety. With the continuous advancement of technology and the continuous improvement of processes, filtration technology will play an even more important role in ethanol production.

[0003] In existing technologies, filtration devices are used to filter impurities from ethanol. However, traditional filtration devices require disassembly and cleaning of the filter plates after a period of use, otherwise the filtration efficiency will be affected. During the disassembly and cleaning process, ethanol cannot be filtered, which will also affect the filtration efficiency. Furthermore, the installation and disassembly of the filter plates are relatively troublesome. Most of them are fixed by bolts, and tools are needed to assist in their installation and disassembly. If the tools are not compatible with the model, it will add difficulty to the installation and disassembly.

[0004] Therefore, a filtration device for ethanol production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a filtration device for ethanol production in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

A feed pipe is provided at the top of the fixed barrel, and a discharge pipe is provided at the bottom of the fixed barrel. An installation frame is provided on the outer wall of the fixed barrel, and support feet are provided at the bottom of the installation frame. The number of filter plates is set to two. An alternating mechanism is provided on the fixed barrel for alternately filtering ethanol from the two filter plates, and the two filter plates are slidably mounted on the alternating mechanism. A limiting mechanism is provided on the alternating mechanism for limiting the insertion of the two filter plates, and the limiting mechanism is mounted on the two filter plates.

[0008] Furthermore, the alternating mechanism includes two fixed shells, which are respectively installed on the front and rear sides of the fixed barrel. Two lead screws are rotatably installed inside the front fixed shell, and two shafts are installed inside the rear fixed shell. Sliding frames are threaded onto the outer walls of both lead screws, and the two sliding frames are slidably installed on the outer walls of the two shafts. The left ends of both lead screws extend outside the fixed shells, and gears are installed on the surfaces of the two extended ends of the lead screws, and the two gears mesh with each other. An L-shaped plate is installed on the left side of the fixed barrel, and a motor is installed on the surface of the L-shaped plate, with the output end of the motor installed on the surface of one of the gears.

[0009] Furthermore, the fixed bucket has two sliding grooves, and the sliding frame is slidably installed on the inner wall of the sliding groove, and the filter plate is slidably installed on the inner wall of the sliding frame.

[0010] Furthermore, a connecting box is installed on the right side of the fixed bucket, and four elastic cloths are provided on the connecting box, with the four elastic cloths respectively set on the two sliding frames.

[0011] Furthermore, the limiting mechanism includes two mounting plates, which are mounted on the surface of the sliding frame. Two cylinders are mounted on the surface of each of the two mounting plates, and the four cylinders are respectively mounted on the surface of the two sliding frames. Springs are sleeved on the outer walls of the four cylinders, and two long rods are slidably mounted on the outer walls of the four springs, with the long rods in contact with the sliding frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention, through the arrangement of lead screws, gears, and sliding frames, allows for efficient operation. Ethanol is poured into a fixed container through the inlet pipe and filtered through the first filter plate. The filtered ethanol is then discharged through the outlet pipe. After a period of use, the motor is activated, driving the connected gears to rotate. The two gears mesh synchronously but in opposite directions, causing the two lead screws to move, resulting in two sliding frames sliding alternately on two shafts. The first sliding frame slides out of the fixed container, while the second slides in, replacing the first filter plate. Filtration can then continue. The operator can pull a fixed rod, causing a long rod to slide on two cylinders and compress two springs, disengaging the rectangular block from the first filter plate. The first filter plate can then be removed for cleaning. This allows for convenient alternation of the two filter plates, saving cleaning and replacement time, improving filtration efficiency, and enabling quick installation and disassembly of the filter plates. The operation is simple and highly practical. Attached Figure Description

A feed pipe 2 is provided at the top of the fixed barrel 1, and a discharge pipe 3 is provided at the bottom of the fixed barrel 1. A mounting frame 4 is provided on the outer wall of the fixed barrel 1, and support legs 5 are provided at the bottom of the mounting frame 4. The number of filter plates 7 is set to two. An alternating mechanism 6 is provided on the fixed barrel 1 for alternately filtering ethanol from the two filter plates 7, and the two filter plates 7 are slidably mounted on the alternating mechanism 6. A limiting mechanism 8 is provided on the alternating mechanism 6 for limiting the insertion of the two filter plates 7, and the limiting mechanism 8 is mounted on the two filter plates 7. In this embodiment, during use, by... The ethanol is poured into the fixed tank 1 through the feed pipe 2. The ethanol is then filtered through the first filter plate 7, and the filtered ethanol is discharged out through the discharge pipe 3. After the first filter plate 7 has been used for a period of time, the second filter plate 7 can be replaced by the alternation mechanism 6, and the filtration can continue. The operator can release the limit of the first filter plate 7 through the limiting mechanism 8, so that the first filter plate 7 can be disassembled and cleaned. This allows for easy alternation of the two filter plates 7, saves cleaning and replacement time, improves filtration efficiency, and allows for quick installation and disassembly of the filter plates 7. The operation is simple and highly practical.

[0027] like Figure 1-2 , Figure 4 As shown, the alternating mechanism 6 includes two fixed housings 601, which are respectively installed on the front and rear sides of the fixed barrel 1. Two lead screws 602 are rotatably mounted inside the front fixed housing 601, and two shafts 603 are installed inside the rear fixed housing 601. Sliding frames 604 are threaded onto the outer walls of both lead screws 602, and the two sliding frames 604 are slidably mounted on the outer walls of the two shafts 603. The left ends of both lead screws 602 extend outside the fixed housings 601, and gears are mounted on the surfaces of both extended ends of the lead screws 602. 605, and two gears 605 mesh with each other. An L-shaped plate 607 is installed on the left side of the fixed barrel 1. A motor 606 is installed on the surface of the L-shaped plate 607, and the output end of the motor 606 is installed on the surface of one of the gears 605. In this embodiment, by starting the motor 606, the gear 605 connected to it is driven to rotate. Since the two gears 605 mesh with each other, they rotate synchronously and in opposite directions. The two lead screws 602 move accordingly, so that the two sliding frames 604 slide on the two shafts 603 respectively, in an alternating motion trajectory.

[0028] like Figure 3-4As shown, the fixed barrel 1 has two sliding grooves, and the sliding frame 604 is slidably installed on the inner wall of the sliding groove. The filter plate 7 is slidably installed on the inner wall of the sliding frame 604. In this embodiment, when the two sliding frames 604 move alternately, one sliding frame 604 slides out of the fixed barrel 1 and the other sliding frame 604 slides into the fixed barrel 1, and the two filter plates 7 move accordingly.

[0029] like Figure 2-3 As shown, a connecting box 608 is installed on the right side of the fixed bucket 1. Four elastic cloths 609 are provided on the connecting box 608, and the four elastic cloths 609 are respectively set on two sliding frames 604. In this embodiment, when the two sliding frames 604 slide alternately, the four elastic cloths 609 will be pulled to block the sliding opening of the connecting box 608. With the cooperation of the connecting box 608 and the four elastic cloths 609, the filter plate 7 can be blocked and sealed to avoid contamination by external dust.

[0030] like Figure 4-5 As shown, the limiting mechanism 8 includes two mounting plates 801, which are mounted on the surface of the sliding frame 604.

Springs 803 are sleeved on the outer walls of each of the four cylinders 802. Two long rods 804 are slidably mounted on the outer walls of the four springs 803, and the long rods 804 are in contact with the sliding frame 604. Rectangular... The rectangular block 805 is inserted into the sliding frame 604 and the filter plate 7. The surfaces of the two long rods 804 are each equipped with a fixing rod 806, which is slidably mounted on the mounting plate 801. In this embodiment, by pulling the fixing rod 806, the long rods 804 slide on the two cylinders 802 and compress the two springs 803, while the rectangular block 805 will disengage from the filter plate 7. At this time, the filter plate 7 can be removed. The installation is also done in the same way, which facilitates the installation and disassembly of the filter plate 7.

[0031] like Figure 4 As shown, handles are installed on the surfaces of both filter plates 7, and protective covers are provided on both handles. In this embodiment, the use of handles with protective covers facilitates the pulling of the filter plates 7.

[0032] In summary, during use, ethanol is poured into the fixed container 1 through the feed pipe 2.

The operator can release the limit of the first filter plate 7 through the limiting mechanism 8, at which point the first filter plate 7 can be disassembled and cleaned. This facilitates the alternation of the two filter plates 7, saves cleaning and replacement time, improves filtration efficiency, and allows for quick installation and disassembly of the filter plates 7. The operation is simple and highly practical. By starting the motor 606, the connected gear 605 is driven to rotate. Since the two gears 605 mesh, they rotate synchronously but in opposite directions, and the two lead screws 602 move accordingly, causing the two sliding frames to... The two sliding frames 604 slide on the two shafts 603 in an alternating motion trajectory. When the two sliding frames 604 move alternately, one sliding frame 604 slides out of the fixed barrel 1 and the other sliding frame 604 slides into the fixed barrel 1, and the two filter plates 7 move accordingly. When the two sliding frames 604 slide alternately, they will pull the four elastic cloths 609 to block the sliding opening of the connecting box 608. With the cooperation of the connecting box 608 and the four elastic cloths 609, the filter plates 7 can be blocked and sealed to prevent them from being contaminated by external dust. By pulling the fixed rod 806, the long rod 804 slides on the two cylinders 802 and compresses the two springs 803, while the rectangular block 805 will disengage from the filter plate 7. At this time, the filter plate 7 can be taken out. The installation is the same, which makes it easy to install and remove the filter plate 7. The handle with a protective sleeve makes it easy to pull the filter plate 7.
