DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Example

[0029] like Figure 1 , 2 As shown in Figures 3 and 4, a novel automatic uniform rehydration equipment for Pu'er tea comprises a double-layer rehydration tank 1, wherein the double-layer rehydration tank 1 comprises an inner tank body 2 and an outer tank body 3, both of which are cylindrical structures; the outer tank body 3 comprises an outer first-section tank body 4, an outer middle-section tank body 5 and an outer tail-section tank body 6 which are arranged in sequence, the inner peripheries of the outer first-section tank body 4 and the outer tail-section tank body 6 are both truncated, and the ends with larger inner diameters of the outer first-section tank body 4 and the outer tail-section tank body 6 are respectively connected to the two ends of the outer middle-section tank body 5, the inner side surface of the outer first-section tank body 4 is provided with a plurality of outer first-section tea guiding strips 7 along its axial direction, and the plurality of outer first-section tea guiding strips 7 are tilted and rotated in the same direction around the axial direction of the outer first-section tank body 4 from the outer first-section tank body 4 to the outer tail-section tank body 6, and the inner periphery of the outer middle-section tank body 5 is A plurality of outer middle tea guide strips 8 are arranged along the axial direction of the side surface, and the plurality of outer middle tea guide strips 8 are tilted and rotated along the same direction around the axial direction of the outer middle tank body 5 from the direction of the outer first section tank body 4 to the direction of the outer tail section tank body 6, and the tilting rotation direction of the plurality of outer middle tea guide strips 8 is the same as the tilting rotation direction of the plurality of outer first section tea guide strips 7; a plurality of outer tail section tea guide strips 9 are arranged along the axial direction of the inner side surface of the outer tail section tank body 6; a plurality of inner layer tea guide strips 10 are arranged along the axial direction of the inner side surface of the inner tank body 2, and the plurality of inner layer tea guide strips 10 are tilted and rotated along the same direction around the axial direction of the inner tank body 2 from the direction of the outer first section tank body 4 to the direction of the outer tail section tank body 6, and the tilting rotation direction of the plurality of inner layer tea guide strips 10 is opposite to the tilting rotation direction of the plurality of outer middle section tea guide strips 8.

[0030] The double-layer rehydration tank 1 is installed in a horizontal position, and the outer periphery of the inner tank body 2 and the inner periphery of the outer middle tank body 5 of the outer tank body 3 can be fixedly connected by connecting rods or other structures, as long as it can ensure that there is a cavity for the tea leaves to reciprocate between the side walls of the inner tank body 2 and the outer tank body 3. The end of the outer first tank body 4 away from the outer middle tank body 5 is the tea inlet and outlet. When rehydrating, the tea leaves and water are sent into the double-layer rehydration tank 1 through the tea inlet and outlet, and the rehydration tank is driven to rotate for rehydration, and water can also be added during the rehydration process. During rehydration, the rotation direction of the double-layer rehydration tank 1 is counterclockwise when viewed from the left side of the double-layer rehydration tank 1. In this rotation direction, the tea leaves are pushed toward the outer middle tank body 5 by the outer first-layer tea guide strip 7 in the outer first-layer tank body 4, and then pushed toward the outer tail tank body 6 by the outer middle-layer tea guide strip 8 in the outer middle tank body 5. Due to the obstruction of the end cover, part of the tea leaves located in the outer tail tank body 6 will enter the inner tank body 2, and be pushed toward the end of the inner tank body 2 close to the tea inlet and outlet by the inner tea guide strip 10 in the inner tank body 2, and thus fall onto the outer tank body 3, forming a reciprocating cycle of rehydration of the tea leaves. After the rehydration is completed, the double-layer rehydration tank 1 is driven to rotate in the opposite direction, and the rehydrated tea leaves can be output from the tea inlet and outlet. This rehydration equipment has a wide range of applications and can be used for rehydration of almost all Pu'er tea raw materials. It has good rehydration uniformity, and the moisture content of the tea leaves after rehydration is slightly different inside and outside. The rehydration efficiency is high, the equipment is not easy to stick to the tea and is easy to clean. After rehydration, the appearance of the tea leaves is relatively intact, the rehydration environment is clean, and the tea quality is better.

[0031] In one embodiment, if Figure 2 and 5 As shown, a tank cover 11 is provided at one end of the outer layer tail section tank body 6 away from the outer layer middle section tank body 5, and a tea guiding round platform 12 is provided on the side of the tank cover 11 facing the outer layer tail section tank body 6, and the periphery of the tank cover 11 is detachably connected to the outer layer tail section tank body 6 by bolts.

[0032] The can lid 11 with the tea-guiding cone 12 can reduce the amount of tea leaves accumulated at the outer tail section of the can body 6. The outer inclined surface of the tea-guiding cone 12 can better guide the tea leaves into the inner can body 2 when the double-layer can body is rotated and rehydrated.

[0033] In one embodiment, if Figure 1 and 2As shown, the device also includes a base 13, and the two ends of the base 13 are located on both sides of the outer first section tank body 4 and the outer tail section tank body 6, and support pulleys 14 are respectively provided. The periphery of the support pulley 14 is provided with a limiting groove 15, and the peripheries of the outer first section tank body 4 and the outer tail section tank body 6 are respectively provided with limiting strips 16 that cooperate with the limiting grooves 15 on the corresponding two support pulleys 14. The base 13 is provided with a driving motor 17 on one side corresponding to the outer tail section tank body 6, and the output shaft of the driving motor 17 is connected to a driving sprocket, and the periphery of the outer tail section tank body 6 is provided with a driven sprocket 18, and the driving sprocket and the driven sprocket 18 are connected by a chain 19.

[0034] The driving motor 17 drives the active sprocket, the chain 19, and the driven sprocket 18 in sequence, thereby driving the double-layer rehydration tank 1 to rotate, and the supporting pulley 14 radially supports the double-layer rehydration tank 1 and reduces the friction between the double-layer rehydration tank 1 and the double-layer rehydration tank 1. The cooperation between the limit groove 15 and the limit bar 16 can prevent the double-layer rehydration tank 1 from axial movement.

[0035] In one embodiment, if Figure 1 and 2 As shown, a water inlet pipe 20 is also provided on the base 13 , one end of the water inlet pipe 20 extends to a port at one end of the outer first tank body 4 away from the outer middle tank body 5 , and the other end of the water inlet pipe 20 is connected to a water source via a flow regulating valve 21 .

[0036] The water required for tea rehydration is transported into the double-layer rehydration tank 1 through the water inlet pipe 20. The water inlet amount of the water inlet pipe 20 is controlled by a flow regulating valve 21. The water inlet pipe 20 can be connected to a water source through a water pump to ensure smooth water supply.

[0037] In one embodiment, if Figure 1 , 2, 5, 6 and 7, the base 13 is provided with a support mechanism for the tank cover 11 on one side corresponding to the outer tail section tank body 6, and the support mechanism includes a support rod 22, a rotating rod 23, a locking rod 24, an axle rod 25 and a locking piece 26, the bottom end of the support rod 22 is fixedly connected to the base 13, one end of the rotating rod 23 is rotatably connected to the top end of the support rod 22, one end of the locking rod 24 is rotatably connected to the other end of the rotating rod 23, and the end surface of the other end of the locking rod 24 is provided with a groove 27, and the two opposite ends of the groove 27 are An axle rod 25 is connected between the side walls, a waist-shaped hole 28 is opened in the middle of the locking plate 26, the axle rod 25 is arranged in the waist-shaped hole 28 of the locking rod 24, the weight of the outer part of any one of the two arc edges of the locking plate 26 is less than the weight of the rest of the locking plate 26, and a support plate 29 is connected to the outer side of the tank cover 11, a part of the support plate 29 has a gap with the outer side of the tank cover 11, and a through hole 30 for the locking rod 24 and the locking plate 26 to pass through is opened on the support plate 29 corresponding to the gap.

[0038] When the double-layer rehydration tank 1 needs to be cleaned or overhauled, the end cover can be opened. When opening the end cover, first remove the bolts connecting the end cover and the outer tail tank body 6, then rotate the rotating rod 23 close to the end cover, insert the locking rod 24 into the through hole 30, and then make the locking piece 26 stand up. The locking piece 26 falls under the action of gravity, so that one arc edge of the waist-shaped hole 28 contacts the shaft rod 25, and keeps the upright state to prevent the end cover from falling off, and then push the rotating rod 23 away from the outer tail tank body 6. When the double-layer rehydration tank 1 is cleaned or overhauled, when installing the end cover, first rotate the rotating rod 23 close to the end cover, then use bolts to connect the end cover and the outer tail tank body 6, and then rotate the locking piece 26. After it is level, rotate the rotating rod 23 to the outer tail tank body 6 so that the locking piece 26 and the locking rod 24 pass through the through hole 30. The weight of the locking piece 26 located outside any one of the two arc edges of the waist-shaped hole 28 is less than the weight of the rest of the locking piece 26, which can ensure that the locking piece 26 is not easy to rotate to a horizontal state without human operation, thereby preventing the end cover from accidentally falling off.

[0039] In one embodiment, if Figure 5 As shown, the support rod 22 is provided with a photoelectric switch 31 whose probe is facing the rotation plane of the rotating rod 23. The probe of the photoelectric switch 31 is located in the fan-shaped area formed when the rotating rod 23 rotates. The signal output end of the photoelectric switch 31 is connected to the signal input end of the controller of the drive motor 17.

[0040] In order to enhance operational safety and prevent the double-layer tank from rotating and possibly injuring the operator when removing the end cover, a photoelectric switch 31 is provided on the support rod 22 to control the drive motor 17. When the rotating rod 23 is located at the initial position away from the end cover, the photoelectric switch 31 is blocked by the rotating rod 23 and is in a normally closed state. When the rotating rod 23 is rotated to approach the end cover, the rotating rod 23 and the photoelectric switch 31 are offset, and the photoelectric switch 31 triggers a signal to control the drive motor 17 to stop running.

[0041] In one embodiment, if Figure 6 and 7 As shown, the side of the groove 27 facing the rotating rod 23 is a slope, and the slope gradually tilts toward the rotating rod 23 from top to bottom, and the outer side of the locking piece 26 located on one side of the waist-shaped hole 28 is a slope matching the slope of the groove 27.

[0042] When Figure 5 For example, when the locking plate 26 is rotated counterclockwise to be horizontal, the arc edge of the waist-shaped hole 28 close to the inclined surface of the locking plate 26 contacts the shaft rod 25 and the inclined surface of the locking plate 26 fits with the inclined surface of the locking rod 24, preventing the locking plate 26 from continuing to rotate counterclockwise, so as to keep the locking plate 26 horizontal so as to pass through the through hole 30 on the support plate 29. In this state, the weight of the locking plate 26 on the side of the inclined surface of the shaft rod 25 close to the locking plate 26 is less than the weight on the other side of the shaft rod 25, and the locking plate 26 will remain horizontal under its own gravity.

[0043] In one embodiment, the device also includes a protective cover that can cover the double-layer rehydration tank 1, and the side wall of the outer tank body 3 can also be provided with an openable and closable sealed door for draining sewage during cleaning, and a collection box for collecting cleaning sewage can be provided on the base 13, and a filter partition can also be provided in the collection box.

[0044] The present invention can also be matched with an operating host station, a feeding elevator, a discharging conveyor belt and a moisture content detector to form a complete automated production line. The operating host station is used to receive signals from a photoelectric switch, control the operation of a drive motor and a flow control valve, and realize the rehydration operation of tea leaves. It is also used to control the feeding elevator to feed tea leaves into the hopper, control the discharging conveyor to send the rehydrated tea leaves away, and control the moisture content detector to detect whether the moisture content of the rehydrated tea leaves is qualified; the operating host station can be a single-chip microcomputer, PLC or other controller, as long as it can realize the above functions. It, the feeding elevator, the discharging conveyor belt and the moisture content detector are all conventional technical means in this field, and will not be repeated here.

[0045] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
