Description

Technical Field

[0001] The invention relates to the technical field of vinegar brewing technology, in particular to an impurity filtering device for vinegar brewing production. Background Art

[0002] In the vinegar production process, in order to ensure the quality and safety of the vinegar liquid, the fermented vinegar liquid must be subjected to a series of filtration treatments, including coarse filtration, fine filtration and fine filtration. These filtration steps are intended to remove various impurities in the vinegar liquid, thereby obtaining a clear and pure product. However, existing vinegar production filtration devices have many problems and challenges in these aspects.

[0003] Traditional filtration equipment often uses independent equipment to complete coarse filtration, fine filtration and fine filtration respectively. This process requires the vinegar liquid to be transferred between different equipment, which not only increases the complexity of the process, but also leads to reduced production efficiency. The transfer process between each device may also cause secondary contamination of the vinegar liquid, affecting the quality of the final product.

[0004] Especially in the coarse filtration stage, traditional coarse filtration equipment will intercept a large number of large particles of impurities. If these impurities cannot be cleaned in a timely and effective manner, the processing efficiency of the coarse filtration equipment will be significantly reduced, and may even cause equipment blockage and shutdown. This not only increases the frequency of maintenance and cleaning, but also affects the efficiency and effect of subsequent fine filtration and fine filtration processes.

[0005] In addition, for filtration devices that integrate coarse filtration, fine filtration and precision filtration functions, the stable operation of each component must be ensured. This usually requires a complex power transmission system to coordinate the work of each part. However, existing technologies make it difficult to achieve a reasonable layout and a simplified transmission mechanism, which increases the manufacturing and maintenance costs of the equipment, and is prone to failures in actual production and has low reliability.

[0091] An assembly cavity A171 is provided between the upper cover plate 14 and the slag discharge tube 21 , and an assembly cavity B172 is provided between the lower cover plate 15 and the rotating plate 321 .

[0092] It also includes a driving assembly, which includes a driving motor 81, a driving shaft A82, and a driving shaft B83. The driving motor 81 is fixedly installed on the upper cover plate 14, the driving shaft A82 is rotatably installed in the assembly cavity A171 and is dynamically connected to the output shaft of the driving motor 81, and the driving shaft B83 is rotatably installed in the assembly cavity B172. The driving shaft A82 and the driving shaft B83 are respectively fixedly connected with a transmission sprocket A821 and a transmission sprocket B831. The transmission sprocket A821 and the transmission sprocket B831 realize chain transmission through a chain.

[0093] The driving shaft A82 is fixedly connected with a driving bevel gear A822 and a driving bevel gear a823 arranged in the assembly cavity A171, the mounting shaft 51 is fixedly connected with a transmission bevel gear A514 which is meshed with the driving bevel gear A822, the slag discharge barrel 21 is fixedly connected with a transmission bevel gear a213 which is meshed with the driving bevel gear a823, and the transmission bevel gear A514 and the transmission bevel gear a213 are arranged in reverse.

[0096] When the driving motor 81 is working, it can drive the driving shaft A82 to operate stably, and then drive the driving shaft B83 to operate synchronously through the combination of the transmission sprocket A821, the transmission sprocket B831 and the chain, thereby ensuring the synchronous operation of the driving bevel gear A822, the driving bevel gear a823, and the driving bevel gear B832, and through the above-mentioned groups of transmission bevel gears, drive the installation shaft 51, the coarse filter cartridge 2 and the rotating disk 321 to operate stably. Since the transmission bevel gear A514 and the transmission bevel gear a213 are arranged in reverse, the coarse filter cartridge 2 and the installation shaft 51 are kept in reverse operation, thereby ensuring that the spiral conveying blade 52 can drive the large particles of impurities in the coarse filter cartridge 2 to be transmitted upward stably.

[0097] Example 5

[0098] See also Figure 4 , Figure 9-11In order to ensure that the fine filter assembly can be stably installed in a relatively rotating manner between the isolation ring 121 and the assembly disk 131, and to ensure that the fine filter assembly can effectively filter the vinegar liquid entering the fine filter chamber 165, the following technical solution is provided.

[0099] The isolation ring 121 is arranged to be higher inside and lower outside, and the inner end of the isolation ring 121 is in sealing contact with the bottom wall of the slag trough 1112 .

[0100] The assembly disk 131 is arranged to be higher outside and lower inside. A recoil drain pipe 1311 is connected to the bottom of the assembly disk 131. A drainage trough 1312 is arranged at the center of the assembly disk 131. A drainage pipe 1313 is connected to the side wall of the drainage trough 1312.

[0101] The fine filtration assembly includes an assembly ring 41, a mounting disk 42, and an ultrafiltration membrane 43 fixedly installed between the assembly ring 41 and the mounting disk 42. The mounting disk 42 is rotatably installed in the assembly ring seat 1314. A mounting sleeve 421 is provided at the center of the mounting disk 42. The mounting sleeve 421 is rotatably installed in the drainage trough 1312. The mounting disk 42 is provided with multiple groups of connecting holes 422 arranged on the periphery of the mounting sleeve 421. The connecting holes 422 are connected with the drainage trough 1312 and the finished product cavity 166.

[0102] The inner side of the isolation ring 121 is kept in contact with the bottom wall of the slag trough 1112 in the assembly seat 111 to form a stable filtrate chamber 163. The assembly is arranged to be high on the outside and low on the inside. In conjunction with the isolation ring 121 that is high on the inside and low on the outside, the formed fine filtration chamber 165 can have a cavity structure that is thin on the outside and thick on the inside, so that the vinegar liquid in the fine filtration chamber 165 can fully contact with the ultrafiltration membrane 43.

[0103] The assembly ring 41 and the installation sleeve 421 provided at the center thereof can cooperate with the assembly ring seat 1314 and the drainage trough 1312, thereby ensuring that the fine filter assembly is stably installed in a relatively rotating manner.

[0104] The drainage trough 1312 can form a cavity with the mounting plate 42, so as to ensure that the filtered vinegar liquid in the finished product cavity 166 is discharged through the connecting hole 422, the drainage trough 1312 and the drainage pipe 1313 while ensuring the overall operation of the fine filter assembly.

[0105] When backwashing the ultrafiltration membrane 43, high-pressure clean water can be injected into the drainage pipe 1313, and then enter the finished product chamber 166 through the drainage trough 1312 and the connecting hole 422, and drive the fine filtration component to operate, thereby realizing the backwashing of the ultrafiltration membrane 43. The sewage after backwashing enters the fine filtration chamber 165, and then is discharged through the backwashing pipe 1311 at the bottom.

[0106] In order to ensure that the fine slag discharge component can be stably installed inside the fine filter component, ensure that the fine slag discharge component can effectively receive the small particle impurities discharged from the slag trough 1112 and discharge them externally, and at the same time prevent the vinegar liquid in the fine filter chamber 162 from directly entering the fine slag discharge component through the slag discharge through hole B1116 and being directly discharged externally, the following technical solution is provided.

[0107] The fine slag discharge assembly includes a slag discharge sleeve 61, a sealing plug 62, and a lifting shaft 63. A receiving hopper 611 is fixedly connected to the top of the slag discharge cylinder 21. The receiving hopper 611 is arranged on the inner side of the isolation ring 121. The receiving hopper 611 is arranged between the slag trough 1112 and the assembly ring 41. The receiving hopper 611 is fixedly connected to the slag trough 1112 and maintains a sealed fit with the assembly ring 41.

[0108] The slag discharge sleeve 61 is arranged in the installation sleeve 421 and maintains a sealing fit with the inner wall of the installation sleeve 421. The top inner wall of the slag discharge sleeve 61 is fixedly connected to the limiting ring 612. The sealing plug 62 is arranged above the limiting ring 612 and maintains a sealing fit with the inner wall of the slag discharge sleeve 61. The slag discharge sleeve 61 is also fixedly connected with a mounting bracket 613 lifting shaft 63, which is fixed to the bottom of the sealing plug 62 and maintains a sliding insertion with the mounting bracket 613.

[0109] The slag discharge sleeve 61 is fixedly connected to the assembly seat 111 through the material receiving hopper 611 at the top to ensure that the fine slag discharge assembly is stably installed in a relatively fixed manner.

[0110] The setting of the receiving hopper 611 can ensure that the small particle impurities intercepted in the fine filter chamber 162 can be transported to the receiving hopper 611 along the slag discharge through hole, and then discharged to the outside through the slag discharge sleeve 61.

[0111] A slag storage chamber 167 is formed between the receiving hopper 611 and the positioning seat, which can store a certain amount of small particle impurities. When discharge is required, the lifting shaft 63 drives the sealing plug 62 to rise so that the sealing plug 62 enters the slag storage chamber 167, and then the slag discharge sleeve 61 is in an open state, so that the small particle impurities in the slag storage chamber 167 can be discharged through the slag discharge sleeve 61.

[0112] The setting of the limiting ring 612 can effectively limit the sealing plug 62 to ensure that the sealing plug 62 is stably assembled in the slag discharge sleeve 61, and the setting of the mounting bracket 613 can ensure that the lifting shaft 63 is stably installed in the slag discharge sleeve 61 in a relatively sliding manner.

[0113] Example 6

[0114] See also Fig. 9 In order to ensure that the pressurizing component can pressurize the vinegar liquid in the liquid collecting chamber 164 and transport it to the fine filter chamber 165, and realize effective pressurization of the vinegar liquid, the following technical solution is provided.

[0115] The pressurizing component includes a pressurizing pump 71 and a pressurizing pipe 72. The middle tank body 12 is connected to a pressurizing pipe A122 which is connected to the liquid collecting chamber 164.

The pressurizing pump 71 is assembled on the pressurizing pipe 72.

[0116] The arrangement of the pressure pipe A122 and the pressure pipe B133 can realize the connection between the liquid collecting chamber 164 and the fine filter chamber 165 through the pressure pipe 72. Through the pressurizing action of the pressure pump 71, it is ensured that the vinegar liquid in the liquid collecting chamber 164 is pressurized and transported to the fine filter chamber 165.

[0117] Example 7

[0118] See also Figure 11-13 In order to ensure that the fine filtration component can operate stably and that the sealing plug 62 and the lifting shaft 63 in the fine slag discharge component can be lifted and lowered stably, the following technical solution is provided.

[0119] It also includes an adjustment component, which includes an adjustment motor 91, a rotating shaft 92, a driving bevel gear C93, a driving bevel gear D94 and two sets of ratchet mechanisms arranged in opposite directions. The output shaft of the adjustment motor 91 is fixedly connected to the rotating shaft 92, and two sets of ratchet mechanisms are installed on the rotating shaft 92. The two sets of ratchet mechanisms are respectively connected to the driving bevel gear C93 and the driving bevel gear D94.

[0120] A transmission bevel gear C423 arranged below the assembly disk 131 is fixedly connected to the periphery of the mounting sleeve 421 , and the transmission bevel gear C423 is meshed with the driving bevel gear C93 .

[0121] A guide through hole 614 is provided on the bottom side wall of the slag discharge sleeve 61, and a lifting bracket 631 slidably installed in the guide through hole 614 is fixedly connected to the lifting shaft 63, and a driving bevel gear D94 is meshedly connected to a transmission bevel gear D632, and a reciprocating screw 633 that is rotationally connected to the lifting bracket 631 is fixedly connected to the axis of the transmission bevel gear D632.

[0122] When the regulating motor 91 rotates forward, the power can be transmitted alone to the ratchet mechanism associated with the driving bevel gear C93, thereby driving the driving bevel gear C93 and the transmission bevel gear C423 to operate, so that the fine filtration component can operate stably, and then cooperate with the input clean water to complete the backwashing of the ultrafiltration membrane 43.

[0123] When the adjustment motor 91 is flipped, the power can be transmitted separately to the ratchet mechanism associated with the driving bevel gear C93, thereby driving the driving bevel gear D94 and the transmission bevel gear D632 to operate, and the reciprocating screw 633 to operate stably, so as to drive the lifting bracket 631, the lifting shaft 63 and the sealing plug 62 to perform periodic reciprocating lifting and lowering motion. When the sealing plug 62 is raised, the slag discharge sleeve 61 can be opened, and when the sealing plug 62 is lowered, the slag discharge sleeve 61 can be blocked.

[0124] The setting of the guide through hole 614 can ensure that the lifting bracket 631 can be lifted and lowered stably in the vertical direction. Inner baffle plates and outer baffle plates are fixedly connected to the inner and outer sides of the lifting bracket 631 respectively. The inner baffle plates and outer baffle plates are respectively attached to the inner wall and outer wall of the slag discharge barrel 21 and seal the guide through hole 614 to prevent small particles of impurities from leaking from the guide through hole 614.

[0125] In order to ensure that the ratchet mechanism can be stably installed on the rotating shaft 92 and that the ratchet mechanism can be stably linked with the driving bevel gear C93 and the driving bevel gear D94, the following technical solution is provided.

[0126] The ratchet mechanism includes an inner ratchet 951, a pawl 952, and a spring 953. The pawl 952 is rotatably mounted on the rotating shaft 92, and the spring 953 is assembled between the pawl 952 and the rotating shaft 92. The inner ratchet 951 is arranged on the inner side of the driving bevel gear C93 and the driving bevel gear D94, and the pawl 952 is kept in meshing with the inner ratchet 951.

[0127] The two sets of ratchet mechanisms are arranged in reverse. When the adjustment motor 91 drives the pawls 952 in the two sets of ratchet mechanisms to operate through the rotating shaft 92, only one set of pawls 952 can transmit power to the corresponding inner ratchet 951, thereby mobilizing the driving bevel gear C93 or the driving bevel gear D94 to operate stably.
