Description
Technical Field
[0001] This disclosure relates to the field of beer production equipment technology, and in particular to an automatic lifting device for the tiller blades of a beer filter tank. Background Technology
[0002] The beer mashing filter tank is a key piece of equipment used in beer brewing to separate wort from afters. The tillers are components fixed on the tiller arm, and their design shape and distribution must ensure the uniformity of tilling and avoid the formation of tilling blind spots. However, the traditional filter tank tiller lifting structure works in conjunction with the tiller mixer. The lifting structure is controlled by a hydraulic structure, which is prone to problems such as insufficient hydraulic oil, aging of seals, control valve failure, and abnormal pump station pressure. The lifting control generally only has upper and lower limit switches, and the limit switches are prone to failure, causing damage to the filter tank structure. Utility Model Content
[0003] The purpose of this invention is to provide an automatic lifting device for the tiller blades of a beer filter tank in order to solve the above-mentioned problems.
[0004] The technical solution disclosed herein is implemented as follows: This disclosure provides an automatic lifting device for the tiller blade of a beer filter tank, including a filter tank, a drain pipe at the bottom of the filter tank, support legs around the bottom of the filter tank, a tiller component inside the filter tank, a support base connected between the support legs and located below the filter tank, a screw jack on the support base and connected to a first motor component, the screw jack having a screw component, one end of the screw component being connected to a receiving part, a support plate on the receiving part, and a second motor component on the support plate; The tillage trough component includes a shaft located inside the filter tank. One end of the shaft extends to the outside of the filter tank and is connected to the output end of the second motor component via a coupling. The other end of the shaft is connected to a tillage arm, on which several tillage blades are arranged at intervals. Through the cooperation of the screw jack and the first motor component, the bottom of the tillage blades is brought closer to or further away from the bottom of the filter tank. A cylinder is provided on the side of the support base away from the screw jack. The other end of the screw passes through the support base and is located inside the cylinder. Several microswitches are arranged at intervals inside the cylinder. Several cams are installed on the part of the screw located in the cylinder. The interval between the cams is the same as the spacing between the microswitches. When the screw rotates and rises, the cams are arranged to contact the microswitches respectively. It also includes a host computer, which is connected to the micro switch, the first motor component, and the second motor component.
[0005] In one embodiment, a filter plate is also provided in the filter tank, and overflow holes are evenly distributed on the filter plate. The shaft passes through the filter plate, and through the cooperation of the screw jack and the first motor component, the bottom of the tiller blade is brought into contact with or away from the filter plate.
[0006] In one embodiment, a guide plate is also provided on the tillage arm. Several guide plates are provided and located between two adjacent sets of tillage blades. The guide plates have openings. When the shaft drives the tiller arm to rotate, the guide plate rotates synchronously, allowing the liquid to pass through the opening into the guide plate.
[0007] In one embodiment, the tiller arm is further provided with a scraping component, which includes a support rod. Two sets of support rods are provided and symmetrically distributed on the side of the tiller arm near the inner wall of the filter tank. A scraper is installed on the support rod. The scraper has a pointed end on the side facing the inner wall of the filter tank and abuts against the inner wall of the filter tank.
[0008] In one embodiment, several openings are provided, and the openings are spaced apart along the length of the guide plate.
[0009] In one embodiment, a lead screw drives a cam to move vertically, causing the cam to abut against the support base or the bottom of the cylinder.
[0010] The advantages or beneficial effects of the above technical solutions include at least the following: This invention discloses an automatic lifting device for the tiller blades in a beer filter tank. A host computer serves as the control center, linking a first motor component to drive a screw jack. The screw jack, receiving part, and bearing plate then drive a second motor component to achieve precise lifting of the tiller tank components. Furthermore, the second motor component, through its rotational layer with the central shaft of the tiller tank components, causes the tiller arm to rotate, loosening the filter residue and preventing clumping. During the lifting process, the cam component at the lower part of the screw jack moves with it. Therefore, when a matching microswitch inside the cylinder is triggered, a signal is fed back to the host computer in real time, achieving stroke limit control to prevent overtravel damage. This solves the problem of existing tiller blade movement malfunctions causing structural damage to the filter tank. Attached Figure Description

[0018] Reference Figures 1-5 An automatic lifting device for the tiller blades in a beer filter tank 1 includes a filter tank 1, an inlet pipe at the top of the filter tank 1, a drain pipe 11 at the bottom of the filter tank 1, and support legs 12 around the bottom of the filter tank 1. A tiller component 2 is installed inside the filter tank 1. The support legs 12 provide stable support for the filter tank 1 and, by raising the filter tank 1, create an installation space below, providing a reasonable installation position for the support base 121 and subsequent drive components. This avoids direct contact between the drive system and the material inside the filter tank 1, reducing the risk of contamination and component corrosion. The support legs 12 are connected to a bearing base 121 located below the filter tank 1. A screw jack 3 is mounted on the bearing base 121 and connected to a first motor component 31. The screw jack 3 has a screw component 32, one end of which is connected to a receiving part 321. A bearing plate 322 is mounted on the receiving part 321, and a second motor component 4 is mounted on the bearing plate 322. Through the combination of the screw jack 3, the first motor component 31, and the screw component 32, the power foundation for the tillage blade lifting is constructed, providing mechanical transmission guarantee for the subsequent realization of automatic lifting. The tillage trough component 2 includes a shaft 21 located inside the filter tank 1. One end of the shaft 21 extends to the outside of the filter tank 1 and is connected to the output end of the second motor component 4 via a coupling. The other end of the shaft 21 is connected to the tillage arm 22. The shaft 21 and the second motor component 4 are connected via a coupling, ensuring that the rotational power of the second motor component 4 can be efficiently and without deviation transmitted to the shaft 21, thereby driving the tillage arm 22 and the tillage blades 23 to rotate stably, reducing the loss in the power transmission process. Several tillage blades 23 are arranged at intervals on the tillage arm 22. Through the cooperation of the screw jack 3 and the first motor component 31, the bottom of the tillage blades 23 is brought close to or away from the bottom of the filter tank 1. A cylinder 5 is provided on the side of the support base 121 away from the screw jack 3. The other end of the screw jack 32 passes through the support base 121 and is located inside the cylinder 5. Several microswitches 51 are arranged at intervals inside the cylinder 5. Several cams 323 are installed on the part of the screw jack 32 located in the cylinder 5. The interval between the cams 323 is the same as the spacing between the microswitches 51. When the screw jack 32 rotates and rises, the cams 323 are respectively in contact with the microswitches 51. The spacing between the cams 323 and the microswitches 51 is matched so that when the screw jack 32 rises and falls to the preset position, the cams 323 can accurately trigger the corresponding microswitches 51 to achieve precise positioning of the lifting stroke. This prevents the tiller blade 23 from exceeding the safe range due to excessive lifting and falling, thereby preventing the tiller blade 23 from falling excessively and hitting the bottom of the trough or rising excessively and leaving the working area. It also includes a host computer, which adopts a programmable controller in the existing technology. The host computer is connected to the micro switch 51, the first motor component 31 and the second motor component 4 respectively. The host computer acts as the control center and realizes the coordinated linkage of various components. The connection between the host computer and the micro switch 51 realizes the real-time acquisition and feedback of limit signals. When the micro switch 51 is triggered, the host computer can quickly respond and control the start and stop of the first motor component 31 to realize intelligent control of the lifting stroke. At the same time, the host computer can flexibly adjust the lifting speed of the first motor component 31 and the trough speed of the second motor component 4 according to the preset program or on-site operation requirements to adapt to different beer filtration process requirements.
[0019] Based on the above structure, by conveying the beer raw materials into the filter tank 1, the tilling component 2 located in the filter tank 1 is connected to the second motor component 4 through the shaft 21. Therefore, when the second motor component 4 is started, it can drive the shaft 21 to rotate, causing the tilling arm 22 to rotate synchronously, thereby allowing the tilling blade 23 to perform a stirring operation inside the filter tank 1. The second motor component 4 is installed on the bearing plate 322 connected to the screw jack 3 through the screw component 32. The screw jack 3 controls the position adjustment of the screw component 32, thereby changing the precise adjustment of the tilling component 2. At the same time, the cam component 323 installed in the cylinder 5 of the screw component 32 can trigger the micro switch 51 in the cylinder 5, and the signal is fed back to the host computer to realize the stroke limit, avoiding overtravel damage, thereby improving the accuracy of movement. It can flexibly adjust the distance between the tilling blade 23 and the bottom of the tank according to the thickness of the material in the filter tank 1, ensuring the tilling effect while avoiding damage caused by hard contact between the tilling blade 23 and the bottom of the tank. The first motor component 31 and the second motor component 4 mentioned above are servo drive motors in the prior art.
[0020] In one embodiment, reference is made to Figure 1 and Figure 2The filter tank 1 is also equipped with a filter plate 13, on which overflow holes 131 are evenly distributed. The shaft 21 passes through the filter plate 13. Through the cooperation of the screw jack 3 and the first motor component 31, the bottom of the tiller 23 is made to abut or move away from the filter plate 13. The filter plate 13 serves as the core filter medium. Beer achieves solid-liquid separation through the overflow holes 131. The tiller 23 also has the dual functions of tilling the trough to loosen the filter residue and scraping the residue on the plate surface, solving the core pain point of filter residue clogging the filter medium in traditional filter tank 1. At the same time, the overflow holes 131 are evenly distributed to ensure sufficient filtration area and improve filtration efficiency.
[0021] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The tiller arm 22 is also equipped with a guide plate 6. Several guide plates 6 are set between two adjacent sets of tiller blades 23. The guide plate 6 has an opening 61. When the shaft 21 drives the tiller arm 22 to rotate, the guide plate 6 rotates synchronously. The liquid can pass through the guide plate 6 through the opening 61. The guide plate 6 breaks the local eddy current generated by the traditional tiller blade stirring and guides the liquid to flow evenly towards the filter plate 13, avoiding the accumulation of local filter residue. The design of the opening 61 balances the guiding effect and the flow efficiency, which not only avoids the increase in energy consumption caused by the liquid impacting the guide plate 6, but also ensures smooth liquid circulation. Several openings 61 are provided, and the openings 61 are distributed at intervals along the length of the guide plate 6. The multiple interval openings 61 make the liquid flow more uniform, further weaken the influence of eddies, ensure that the pressure and flow rate in each area of the filter tank 1 are consistent, and at the same time, the liquid resistance is evenly distributed, reducing the load fluctuation when the tiller rotates, reducing motor wear, and improving the stability of equipment operation.
[0022] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The tiller arm 22 is also equipped with a scraper component 7, which is used to scrape the filter tank 1. The scraper component 7 includes a support rod 71. Two sets of support rods 71 are provided and symmetrically distributed on the side of the tiller arm 22 near the inner wall of the filter tank 1. The two sets of support rods 71 can improve the scraping efficiency. A scraper 72 is installed on the support rod 71. The scraper 72 has a pointed tip 721 on the side facing the inner wall of the filter tank 1 and abuts against the inner wall of the filter tank 1. The pointed tip 721 is in close contact with the inner wall of the filter tank 1. During rotation, it scrapes away the filter residue, beer scum and other deposits attached to the tank wall. The scraper component 7 can replace manual cleaning of the tank wall, reduce downtime for cleaning, avoid the growth of bacteria or spoilage of the deposits on the tank wall, reduce the risk of beer contamination, and at the same time, the absence of deposits on the tank wall reduces the resistance to liquid flow and reduces the energy consumption of the motor drive.
[0023] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The cam 323 is driven by the lead screw 32 to move vertically, so that the cam 323 abuts against the support base 121 or the bottom of the cylinder 5. The electrical limit set by the micro switch 51 is the first-level protection, while the mechanical limit of the cam 323 abutting against the support base 121 and the bottom of the cylinder 5 is the second-level protection. The dual limit design avoids the risk of single limit failure and prevents the tiller blade from overtraveling and hitting the filter plate 13, which would cause damage.

They are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0025] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
