Abstract
Description
Technical Field
[0001] This utility model relates to a filter tank blade lifting and driving system, belonging to the technical field of beer brewing equipment. Background Technology
[0002] During beer brewing, the wort needs to be filtered in a filter tank to separate the wort and afterburner. At this time, the filter tank's tillering system starts working, with a drive unit moving the tillers to continuously agitate the wort within the filter tank. This agitation evenly disperses the wort particles, preventing clogging of the filter media (such as the filter screen and afterburner), thus ensuring the wort flows out smoothly.
[0003] Currently, to avoid creating blind spots in the tillage trough, the tillage system in the filter tank is usually equipped with a lifting device to raise and lower it. Traditional lifting devices include pneumatic cylinders or hydraulic cylinders. However, these devices require a large installation space and are inconvenient to install and difficult to control.
[0004] The drive unit above the filter tank drives the blades inside the tank to rotate via a transmission shaft. The transmission shaft is positioned and sealed by a sealing and positioning mechanism above the filter tank. The sealing and positioning mechanism requires a certain amount of installation space, resulting in a relatively high equipment height and potential instability.
[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0006] This utility model addresses the shortcomings of the prior art by providing a filter tank blade lifting and driving system, which not only saves the installation space required for the lifting power device, but also saves the installation space required for the sealing and positioning mechanism of the drive shaft.
[0007] To solve the above technical problems, the present invention adopts the following technical solution:
[0008] A filter tank blade lifting and driving system includes a blade assembly, which is fixedly installed at the bottom of a drive shaft. The drive shaft passes vertically through a reducer and a bushing. The top end of the drive shaft is rotatably connected to the bottom end of a worm gear screw jack via a connector. The worm gear screw jack is mounted above the reducer via a support assembly. The reducer is fixedly connected to the top flange of the filter tank. The bushing is fixedly installed inside the top flange, with its bottom extending to the top of the filter tank's inner cavity. A rotating seal is installed inside the bottom end of the bushing.
[0009] Furthermore, the drive shaft is connected to the reducer via a flat key.
[0010] Furthermore, the connecting member is fixed to the bottom end of the screw of the worm gear screw jack, the top end of the transmission shaft is located inside the connecting member, and the transmission shaft is rotatably connected to the connecting member through two bearings arranged at the top and bottom.
[0011] Furthermore, the support assembly includes a bottom flange, a support shaft, and a top flange arranged sequentially from bottom to top.
[0012] Furthermore, there are multiple support shafts, with the bottom end of the support shaft fixed to the bottom flange by a threaded connection, and the top end of the support shaft fixed to the top flange by a threaded connection.
[0013] Furthermore, the bottom flange is connected to the top of the reducer.
[0014] Furthermore, the top flange is connected to the worm gear screw jack.
[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0016] This invention uses a worm gear screw jack to provide power for the lifting and lowering of the tillage blade assembly inside the filter tank. The worm gear screw jack drives the lifting and lowering of the tillage blade assembly through a drive shaft. This invention also uses a horizontal hollow reducer to provide power for the rotation of the tillage blade assembly. The reducer can transmit torque to the drive shaft, and the drive shaft can move up and down along the inside of the reducer.
[0017] Compared with traditional pneumatic or hydraulic cylinder lifting methods, this invention saves installation space, is easier to install, and has a simpler control method. The drive shaft in this invention utilizes an extended bushing inside the filter tank for sealing and positioning, saving space and providing greater stability.
[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0024] like Figures 1-3 As shown in the figure, this utility model provides a filter tank tiller lifting and driving system, including tiller assembly 1. Tiller assembly 1 is fixedly installed at the bottom of drive shaft 2. Drive shaft 2 passes through reducer 5 and bushing 3 in a vertical direction. The top end of drive shaft 2 is rotatably connected to the bottom end of screw of worm gear screw jack 7 through connector 8. Worm gear screw jack 7 is installed above reducer 5 through support assembly 6.
[0025] The reducer 5 is a horizontal hollow reducer, which is fixedly connected to the top flange 4 of the filter tank 10.
[0026] The bushing 3 is fixedly installed inside the top flange 4 of the tank, and the bottom of the bushing 3 extends to the top of the inner cavity of the filter tank 10. The bushing 3 positions the drive shaft 2.
[0027] A rotating seal 9 is installed inside the bottom end of the bushing 3 to prevent liquid from overflowing upwards.
[0028] The drive shaft 2 is connected to the reducer 5 via a key. The reducer 5 can transmit torque to the drive shaft 2, and the drive shaft 2 can move up and down along the inside of the reducer 5.

The transmission shaft 2 is rotatably connected to the connecting member 8 through two bearings arranged at the top and bottom. The lead screw of the worm gear screw jack 7 can drive the transmission shaft 2 to perform lifting and lowering movements, and the two are rotatably connected without transmitting torque between them.
[0030] The support assembly 6 supports and fixes the worm gear screw jack 7. The support assembly 6 includes a bottom flange 61, a support shaft 62 and a top flange 63 arranged sequentially from bottom to top. There are multiple support shafts 62.
