Description

Technical Field

[0001] The invention belongs to the technical field of beer production equipment, and particularly relates to a hops efficient feeding and fermentation liquid circulation device. Background Art

[0002] In the beer brewing industry, as consumers' demand for beer quality and flavor diversity continues to rise, refinement and automation of production processes have become key to enhancing companies' competitiveness. Hops, the core ingredient that imparts beer's unique aroma, bitterness, and antiseptic properties, dictate the flavor stability and consistency of the beer. Efficient circulation and filtration of the fermentation broth is crucial for ensuring a smooth fermentation process, improving raw material utilization, and reducing production costs.

[0003] Problems with existing technologies: At present, the hop feeding equipment used by most beer production companies relies on manual operation. From the weighing of hops to the feeding of hops into the fermentation tank, the errors and inconsistent rhythm of manual operation are prominent problems. On the one hand, manual weighing cannot guarantee the high accuracy of the hop feeding amount of each batch, resulting in fluctuations in beer flavor and affecting product quality. On the other hand, manual operation is inefficient and cannot meet the needs of large-scale continuous production, which increases labor costs and management difficulty. In addition, the existing hop feeding device has a low degree of integration, and multiple links require independent equipment and drive devices, which not only takes up a large amount of production space, but also makes it difficult to ensure the coordination and reliability of equipment. Failures occur frequently and maintenance costs remain high. Summary of the Invention

Circulation pipes 3 connected to the mixing box 2 are provided at the bottom of both sides of the fermentation tank body 1, which are used for circulating and filtering the fermentation liquid in the fermentation tank body 1. A venturi tube 11 is provided at one end of the circulation pipe 3 near the mixing box 2, which is used to increase the flow rate of the fermentation liquid and improve its impact force; A feeding mechanism 5 is provided on the top of the mixing box 2. The feeding mechanism 5 includes a plurality of feeding cylinders 51 arranged in a circumferential direction on the top of the mixing box 2. The discharge ports of the feeding cylinders 51 are connected to the top of the mixing box 2. An auger 57 for transporting hops is provided inside the feeding cylinders 51. A weighing box 52 is connected to one side of the top of the feeding cylinders 51. A weighing mechanism 6 for weighing the hops is provided inside the weighing box 52. The top of the weighing box 52 is connected to a hopper 53. A sealing cover 12 is provided on one side of the top of the hopper 53. The hopper 53 consists of a bucket-shaped portion and a vertical portion, and the bottom end of the bucket-shaped portion is connected to the vertical portion. A second rotating shaft 56 is provided on one side of the top of the hopper 53. A first rotating shaft 54 is rotatably installed through the top of the hopper 53. The bottom end of the first rotating shaft 54 is located in the vertical portion and is provided with a first spiral blade 55 for controlling the hops to fall into the weighing box 52. The top end of the first rotating shaft 54 is provided with a third bevel gear set connected to the second rotating shaft 56. A support frame 511 is provided on one side of the top of the feeding barrel 51. Two mounting rods 512 are provided on the top of the support frame 511. The middle parts of the two mounting rods 512 are rotatably connected to the support frame 511. A limit slider 513 is fixed between the two ends of the two mounting rods 512. A mounting block 59 is provided on the outside of each end of the mounting rod 512. The outer wall of the mounting block 59 is penetrated by a waist groove 510 to which the limit slider 513 is slidably connected. The second rotating shaft 56 and one end of the auger 57 are both slidably provided with a telescopic shaft 58 rotatably connected to the mounting block 59. One end of the telescopic shaft 58 passes through the mounting block 59 and is fixed with a first bevel gear 515. A motor 516 is provided on the top of the mixing box 2. The output shaft of the motor 516 is fixed with a drive shaft. Two second bevel gears 517 that cooperate with the first bevel gear 515 are provided on the outer wall of the drive shaft. A hydraulic cylinder 514 for driving the mounting rod 512 to rotate is provided on the top of the feeding barrel 51.

[0022] According to the above structure, when in use, hops are put into the feeding hopper 53, the sealing cover 12 is covered, and the hydraulic cylinder 514 is started. The hydraulic cylinder 514 drives the mounting block 59 at the bottom to move horizontally, and through the cooperation of the waist groove 510 and the limit slider 513, the mounting rod 512 is driven to rotate, thereby controlling the first bevel gear 515 at both ends of the mounting rod 512 to engage with the corresponding second bevel gear 517; when the first bevel gear 515 and the second bevel gear 517 at the top are engaged, the first bevel gear 515 and the second bevel gear 517 at the bottom are separated, and the motor 516 is started to drive the telescopic shaft 58 to rotate, and the telescopic shaft 58 drives the second rotating shaft 56 to rotate, and the second rotating shaft 56 drives the first rotating shaft 54 to rotate through the third bevel gear set, and the first rotating shaft 54 drives the first spiral blade 55 to rotate, so as to transport the hops in the feeding hopper 53 to the weighing box 52; When the pressure sensor on the weighing mechanism 6 detects that the hops have reached the set value, the hydraulic cylinder 514 is controlled to drive the first bevel gear 515 at the bottom of the mounting rod 512 to engage with the second bevel gear 517, and the first bevel gear 515 at the top is separated from the second bevel gear 517. At this time, the first spiral blade 55 stops rotating, and the feeding of hops into the weighing box 52 is stopped. At the same time, the two weighing plates 61 on the weighing mechanism 6 open, and the hops on them fall into the feeding barrel 51. The motor 516 cooperates with the telescopic shaft 58 to drive the auger 57 to rotate, and the hops in the feeding barrel 51 are transported to the mixing box 2. The outer surface of the telescopic shaft 58 is provided with a limited guide rail, and one side of the second rotating shaft 56 and the auger 57 is provided with a guide groove that is slidably connected to the telescopic shaft 58. Under the condition of not affecting the rotation transmission, the telescopic shaft 58 can be freely extended and retracted, which facilitates the normal use of the equipment. The structure is simple and does not require manual intervention in the feeding, weighing and conveying links, which reduces labor costs and avoids fluctuations in production efficiency caused by inconsistent manual operation rhythms. The entire process from the hops entering the feeding hopper 53 to the final conveying to the mixing box 2 is automatically completed by the mechanical structure and control system, which significantly improves the continuity and efficiency of the beer production process. With the help of the meshing state switching of the bevel gear set, the connection of the hops in the three process links of feeding, weighing and feeding is accurately controlled. This integrated design avoids the cumbersome layout of multiple sets of independent drive devices, simplifies the equipment structure, and improves the reliability and coordination of the system.

[0023] like Figure 3-Figure 4 As shown, the weighing mechanism 6 includes two weighing plates 61 symmetrically arranged inside the weighing box 52, and the two weighing plates 61 are rotatably connected to the inside of the weighing box 52. The outer walls of the weighing plates 61 are provided with pressure sensors, and both ends of the hinge shaft of the weighing plates 61 extend to the outside of the weighing box 52 and are provided with first gears 62; A U-shaped plate 63 is slidably installed between the outer walls of both sides of the weighing box 52. Two tooth grooves 64 are obliquely symmetrically opened on both sides of the U-shaped plate 63. The tooth grooves 64 are engaged with the first gear 62 and are used to drive the two weighing plates 61 to rotate synchronously to open or close. Two connecting rods 65 are rotatably installed on one side of the U-shaped plate 63, and the other end of the connecting rod 65 is connected to the bottom side of the mounting rod 512.

[0024] According to the above structure, before weighing the hops, the opposite sides of the two weighing plates 61 are fitted and sealed. When the hops are fed from the feeding hopper 53 to the two weighing plates 61, the pressure sensors provided on the weighing plates 61 weigh the hops that fall in. When the set value is reached, the first spiral blade 55 on the feeding hopper 53 stops feeding, and the mounting rod 512 rotates, pulling the connecting rod 65 to move. The connecting rod 65 drives the U-shaped plate 63 to move, and the U-shaped plate 63 drives the tooth groove 64 to move. The tooth groove 64 engages with the first gear 62, driving it to rotate. The first gear 62 drives the two weighing plates 61 to rotate downward and open through the hinge shaft, so that the hops on the weighing plates 61 fall into the feeding barrel 51. A third slide block is provided on both sides of the weighing box 52. A third sliding groove is provided on the outer wall of the U-shaped plate 63 for sliding connection with the third slide block, which makes the movement of the U-shaped plate 63 more stable and improves the stability of the cooperation between the tooth groove 64 and the first gear 62. The two tooth grooves 64 on the same side are arranged obliquely and symmetrically, so that the two first gears 62 can rotate synchronously in opposite directions, making it convenient to control the weighing plates 61 on both sides to fit together and close, or rotate downward to open, so as to facilitate the control of hop discharge. This structure realizes real-time monitoring and precise control of hop weight, ensuring the accuracy of the ratio and avoiding errors in manual operation, providing a key guarantee for the stability of the subsequent mixing process; in addition, the close fitting design of the weighing plate 61 and the sliding guide mechanism of the U-shaped plate 63 form a closed material carrying space during the weighing process, effectively preventing the contamination of hops by external dust and moisture, and avoiding the scattering and loss of hop particles during the weighing process.

[0025] like Figure 5-Figure 6 As shown, a mixing and stirring mechanism 7 is provided inside the mixing box 2; The mixing and stirring mechanism 7 includes an axial tube 71 that passes through the center of the fermentation tank body 1. The top of the axial tube 71 is sealed and rotatably connected to the water outlet of the water pump 4 through a connector. The bottom end of the axial tube 71 is located in the fermentation tank body 1 and is provided with a U-shaped tube 72 that passes through it. The two vertical parts of the U-shaped tube 72 are both provided with multiple nozzles 73. A third rotating shaft 74 is rotatably mounted through the center of the mixing box 2. A water wheel blade 75 is fixed to the outer wall of the third rotating shaft 74 located inside the mixing box 2. A second gear set 76 connected to the shaft tube 71 is fixed to the outer wall of the third rotating shaft 74 and located outside the mixing box 2. The outer wall of the third rotating shaft 74 is provided with a brush plate 10 for cleaning the first filter plate 9; The plurality of nozzles 73 are arranged in an equidistant vertical array on the two vertical portions of the U-shaped tube 72 , and the two nozzles 73 located on the two vertical portions in the same horizontal plane are distributed symmetrically with respect to the center.

[0026] According to the above structure, when the hops enter the mixing box 2, the fermentation liquid at the bottom of the fermentation tank body 1 is transported to the mixing box 2 through the circulation pipe 3 by the water pump 4, and then the fermentation liquid in the mixing box 2 passes through the first filter plate 9 and enters the shaft pipe 71, enters the U-shaped tube 72 from the shaft pipe 71, and is sprayed out from the nozzle 73 and returns to the fermentation liquid in the fermentation tank body 1. The flow rate of the fermentation liquid is increased by the provided venturi tube 11, and the fermentation liquid sprayed from the circulation pipe 3 hits the water wheel blade 75, and the water wheel blade 75 rotates and stirs the hops in the mixing box 2 so that it can be preliminarily mixed with the fermentation liquid. At the same time, the water wheel blade 75 drives the third rotating shaft 74 to rotate, and the third rotating shaft 74 drives the shaft pipe 71 to rotate through the second gear set 76, and the shaft pipe 71 drives the U-shaped tube 72 to rotate, stirring the fermentation liquid in the fermentation tank body 1, so that the hops and the fermentation liquid are mixed; The plurality of nozzles 73 are symmetrically distributed around the center, and the reaction force of the fermentation liquid sprayed out by the nozzles 73 is used to drive the U-shaped tube 72 to rotate. No separate driving device is required, which reduces energy consumption and further drives the U-shaped tube 72 to rotate, which is more energy-saving and environmentally friendly. This structure uses the water impeller 75 to initially stir the hops in the mixing box 2, and at the same time, the U-shaped tube 72 rotates to stir the fermentation liquid in the fermenter, forming a double stirring mechanism. This allows the hops and fermentation liquid to fully contact each other in the mixing box 2 and the fermenter, significantly improving the mixing efficiency and ensuring the fermentation quality. While achieving the stirring function, it fully utilizes fluid power, making the entire system compact in structure, high in space utilization, and convenient for equipment installation and maintenance.

[0027] like Figure 7-10 As shown, the outer wall of the circulation pipe 3 is provided with a filtering mechanism 8 for filtering the fermentation liquid. The filtering mechanism 8 includes a mounting cylinder 81 arranged at the bottom of both sides of the fermentation tank body 1. The bottom of the mounting cylinder 81 is connected to a collecting box 82. A processing port is provided on one side of the collecting box 82. A rubber fixing seat 83 is provided on the inner side of the mounting cylinder 81. A frustum cover 84 is fixed on the top of the rubber fixing seat 83. A plurality of filter holes 85 are vertically distributed on the outer surface of the frustum cover 84. A lower material cover 86 is provided on the top of the rubber fixing seat 83 and located inside the frustum cover 84. The upper and lower ends of the lower material cover 86 are both open structures. An annular cavity is formed between the frustum cover 84 and the lower material cover 86. A spiral plate 87 is provided in the annular cavity. A collecting hopper 88 is fixed through the top opening of the lower material cover 86. The spiral plate 87 spirally surrounds the outer wall of the discharge cover 86. The outer edge of the spiral is fixedly connected to the inner wall of the frustum cover 84, dividing the annular cavity into a spiral guide cavity for guiding the fluid to flow along the spiral path. The spiral guide cavity cooperates with the filter holes 85 on the outer surface of the frustum cover 84 to achieve the filtering function. The outer wall of the collection hopper 88 is provided with a collection port 89 connected to the spiral guide cavity. An acceleration cover 810 is provided on the inner side of the mounting cylinder 81 and above the conical cover 84. A fourth rotating shaft 811 is provided on the top of the acceleration cover 810. A turbine 812 is provided on the top of the fourth rotating shaft 811. Elastic sheets 813 are symmetrically provided on the bottom end of the fourth rotating shaft 811. A knocking block 814 is provided on the outer wall of the elastic sheet 813. The outer surface of the conical cover 84 has a plurality of protrusions 815 that cooperate with the knocking block 814 in an equidistant array along the circumferential direction.

[0028] According to the above structure, under the drive of the water pump 4, the fermentation liquid at the bottom of the fermentation tank body 1 enters the spiral guide cavity through the connecting pipe on the side of the frustum cover 84, the fermentation liquid flows in a spiral shape, and passes through the filter hole 85, while the impurities in the fermentation liquid remain in the spiral guide cavity. Under the impact of the fermentation liquid, it follows the spiral plate 87 through the collecting port 89 into the collecting hopper 88, and then through gravity, the impurities pass through the discharge cover 86 and fall into the collection box 82 for unified collection. The fermentation liquid passing through the filter hole 85 then passes through the acceleration cover 810, and the flow rate is increased by the acceleration cover 810 to impact the turbine 812. The rotation of the turbine 812 drives the fourth rotating shaft 811 to rotate, and the fourth rotating shaft 811 drives the knocking block 814 on the elastic sheet 813 to knock the protrusion 815, causing the frustum cover 84 to vibrate, thereby preventing impurities from clogging the filter hole 85, thereby improving the filtering effect of the equipment. Compared with the traditional static filtration device, no additional backwashing system or manual intervention is required, which significantly improves the automation level and operation reliability of the equipment. This structure utilizes the centrifugal effect generated by the spiral flow to cause the impurities in the fermentation liquid to gather toward the spiral plate 87 under the action of inertia. Combined with the aperture screening of the filter pores 85, efficient separation of solid and liquid is achieved, avoiding the accumulation of impurities in the filtration area and ensuring the continuity of the filtration process. The unified collection method of the collection box 82 facilitates subsequent centralized processing and reduces manual cleaning costs.

[0029] The working principle of the present invention is as follows: when in use, first put hops into the feeding hopper 53, cover the sealing cover 12, start the hydraulic cylinder 514, the hydraulic cylinder 514 drives the bottom mounting block 59 to translate, and under the cooperation of the waist groove 510 and the limit slider 513, drives the mounting rod 512 to rotate, thereby controlling the first bevel gear 515 at both ends of the mounting rod 512 to engage with the corresponding second bevel gear 517; when the first bevel gear 515 at the top engages with the second bevel gear 517, the first bevel gear 515 at the bottom is separated from the second bevel gear 517, and the motor 516 is started to drive the telescopic shaft 58 to rotate, the telescopic shaft 58 drives the second rotating shaft 56 to rotate, the second rotating shaft 56 drives the first rotating shaft 54 to rotate through the third bevel gear set, and the first rotating shaft 54 drives the first spiral blade 55 to rotate, so that the hops in the feeding hopper 53 are transported to the weighing box 52; When the pressure sensor on the weighing mechanism 6 detects that the hops have reached the set value, the hydraulic cylinder 514 is controlled to drive the first bevel gear 515 at the bottom of the mounting rod 512 to mesh with the second bevel gear 517, and the first bevel gear 515 at the top is separated from the second bevel gear 517. At this time, the first spiral blade 55 stops rotating and stops feeding the weighing box 52. At the same time, the mounting rod 512 rotates and pulls the connecting rod 65 to move, and the connecting rod 65 drives the U-shaped plate 63 to move. The U-shaped plate 63 drives the tooth groove 64 to move, and the tooth groove 64 meshes with the first gear 62, driving the first gear 62 to rotate. The first gear 62 drives the two weighing plates 61 to rotate downward and open through the hinge shaft, so that the hops on the weighing plates 61 fall into the feeding barrel 51; then, the motor 516 cooperates with the telescopic shaft 58 to drive the auger 57 to rotate, and the hops in the feeding barrel 51 are transported to the mixing box 2; When the hops enter the mixing box 2, the water pump 4 transports the fermentation liquid at the bottom of the fermentation tank body 1 to the mixing box 2 through the circulation pipe 3. The fermentation liquid passes through the first filter plate 9 and enters the shaft pipe 71. From the shaft pipe 71, it enters the U-shaped tube 72, and then is sprayed out from the nozzle 73 and returns to the fermentation liquid in the fermentation tank body 1; the venturi tube 11 on the circulation pipe 3 increases the flow rate of the fermentation liquid, and the sprayed fermentation liquid hits the water wheel blade 75. The water wheel blade 75 rotates to stir the hops in the mixing box 2 so that it is preliminarily mixed with the fermentation liquid. At the same time, the water wheel blade 75 drives the third rotating shaft 74 to rotate. The third rotating shaft 74 drives the shaft pipe 71 to rotate through the second gear set 76. The shaft pipe 71 drives the U-shaped tube 72 to rotate, stirring the fermentation liquid in the fermentation tank body 1 so that the hops and the fermentation liquid are fully mixed; when the third rotating shaft 74 rotates, the brush plate 10 on its outer wall cleans the first filter plate 9 to prevent impurities from clogging; Driven by the water pump 4, the fermentation liquid at the bottom of the fermentation tank body 1 enters the spiral guide cavity through the connecting pipe on one side of the frustum cover 84, the fermentation liquid flows in a spiral shape and passes through the filter hole 85, and the impurities remain in the spiral guide cavity. Under the impact of the fermentation liquid, it follows the spiral plate 87 through the collecting port 89 into the collecting hopper 88, and then passes through the discharge cover 86 by gravity and falls into the collecting box 82 for unified collection; the fermentation liquid passing through the filter hole 85 passes through the acceleration cover 810, and the acceleration cover 810 increases the flow rate to impact the turbine 812. The rotation of the turbine 812 drives the fourth rotating shaft 811 to rotate, and the fourth rotating shaft 811 drives the knocking block 814 on the elastic sheet 813 to knock the protrusion 815, causing the frustum cover 84 to vibrate, thereby preventing impurities from clogging the filter hole 85 and improving the filtering effect.
