Description

Technical Field

[0001] The utility model relates to the technical field of tea extraction, in particular to tea extraction equipment. Background Art

[0002] Tea extraction mainly uses finished tea leaves or semi-finished tea leaves as raw materials, extracts soluble substances in tea leaves with room temperature extraction liquid, and filters out tea residues to obtain tea juice, which has the advantages of being easy to carry and does not contain pesticide residues.

[0003] When using existing tea extraction equipment, tea leaves and extraction liquid are usually added into an extraction tank for extraction. After the extraction is completed, in order to prevent the tea residue from being mixed in the liquid, a scoop net or other tools are usually used to filter out the tea residue. The cleaning process takes a long time and is likely to cause the subsequent tea residue to be mixed in the tea leaves. At the same time, during the cleaning process, personnel are required to operate back and forth to filter out the tea residue, which is labor-intensive. At the same time, the tea leaves are left to stand still in the extraction liquid to soak, and the extraction efficiency is low. Utility Model Content

[0004] The main purpose of the utility model is to provide a tea extraction device, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tea extraction device comprises an extraction tank, wherein a liquid adding valve and a feed inlet are arranged at the top of the extraction tank, a guide tank is fixedly connected to the lower position of the outer ring of the extraction tank, and a slag discharge mechanism is arranged inside the extraction tank;

[0007] The slag discharge mechanism includes a rotating rod, which is rotatably installed at the top center position of the extraction tank, and the bottom end of the rotating rod passes through the extraction tank and is connected to a spiral auger, a push rod is slidably installed at the center position of the upper and lower ends of the spiral auger, the bottom end of the push rod is fixedly connected to a blocking plate, the top of the rotating rod is fixedly connected to an electric telescopic rod, and the telescopic rod of the electric telescopic rod passes through the upper and lower ends of the rotating rod and is connected to the top of the push rod, a partition is fixedly connected to the center position of the interior of the diversion tank, a filter screen is provided on the outer circle of the extraction tank and above the partition, and a drain valve pipe is provided through one side of the diversion tank and above the partition.

[0008] As a further solution of the utility model, the blocking plate is located below the partition, the top end of the blocking plate is fitted with the bottom end of the extraction tank, and a gap is left between the outer circle of the blocking plate and the inner circle of the diversion tank.

[0009] As a further solution of the utility model, the top surface of the blocking plate is conical, and the bottom end of the diversion tank is provided with a discharge port.

[0010] As a further solution of the utility model, the outer ring of the spiral auger is in contact with the inner wall of the extraction tank, and the bottom end of the spiral auger does not contact the blocking plate.

[0011] As a further solution of the utility model, a slag discharge motor is installed on the side of the top of the extraction tank away from the liquid filling valve, and the driving shaft of the slag discharge motor is transmission-connected to the rotating rod through a transmission wheel set.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model is provided with a slag discharge mechanism in conjunction with the extraction tank, and the filter screen cooperates with the liquid discharge valve pipe to facilitate the discharge of the extracted tea juice. After the tea juice is discharged, the electric telescopic rod pushes the blocking plate away from the extraction tank, so that the tea residue can fall from the bottom of the extraction tank, thereby reducing the cumbersome steps of personnel using tools to clean up and facilitating the reduction of labor intensity.

[0014] By rotating the spiral auger in the extraction tank, the tea leaves at the bottom of the extraction tank can be transported to the upper part again during extraction, which reduces the probability of tea leaves sedimentation and stratification, facilitates cyclic stirring extraction, reduces the time required for extraction, and improves processing efficiency.

[0015] During cleaning, the spiral auger can be reversed to push down most of the tea residues stuck inside the extraction tank, thereby reducing the probability of tea residues remaining and improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a tea extraction equipment comprises an extraction tank 1, a liquid adding valve 3 and a feed port 4 are arranged at the top of the extraction tank 1, a guide tank 2 is fixedly connected to the lower position of the outer ring of the extraction tank 1, and a slag discharge mechanism 5 is arranged inside the extraction tank 1;

[0022] The slag discharge mechanism 5 includes a rotating rod 6, which is rotatably installed at the top center position of the extraction tank 1, and the bottom end of the rotating rod 6 passes through the extraction tank 1 and is connected to a spiral auger 7, a push rod 10 is slidably installed at the center position of the upper and lower ends of the spiral auger 7, a blocking plate 9 is fixedly connected to the bottom end of the push rod 10, an electric telescopic rod 8 is fixedly connected to the top of the rotating rod 6, and the telescopic rod of the electric telescopic rod 8 passes through the upper and lower ends of the rotating rod 6 and is connected to the top of the push rod 10, a partition is fixedly connected to the center position of the inside of the diversion tank 2, a filter screen 12 is arranged on the outer circle of the extraction tank 1 and above the partition, and a drain valve pipe 11 is arranged through one side of the diversion tank 2 and above the partition.

[0023] In this embodiment, the blocking plate 9 is located below the partition, the top of the blocking plate 9 is in contact with the bottom of the extraction tank 1, and a gap is left between the outer circle of the blocking plate 9 and the inner circle of the diversion tank 2. When the blocking plate 9 is away from the extraction tank 1, the tea leaves can slide into the lower part of the diversion tank 2 through the gap, making it easy to discharge the tea leaves.

[0024] In this embodiment, the top surface of the blocking plate 9 is conical, and a discharge port 15 is provided at the bottom end of the diversion tank 2. The conical configuration facilitates the sliding of tea residues, and by opening the discharge port 15, the tea residues inside the diversion tank 2 can be easily discharged.

[0025] In this embodiment, the outer ring of the spiral auger 7 is in contact with the inner wall of the extraction tank 1, and the bottom end of the spiral auger 7 does not contact the blocking plate 9. The slag discharge motor 14 drives the spiral auger 7 to rotate in the extraction tank 1, so as to push down the tea leaves stuck to the inside of the extraction tank 1 and improve the cleaning effect. At the same time, the spiral auger 7 does not contact the blocking plate 9 to avoid collision damage.

[0026] In this embodiment, a slag discharge motor 14 is installed on the side of the top of the extraction tank 1 away from the liquid filling valve 3. The driving shaft of the slag discharge motor 14 is connected to the rotating rod 6 through the transmission wheel group 13. By starting the slag discharge motor 14, the rotating rod 6 is driven to rotate, which is convenient for transmission.

[0027] It should be noted that the utility model is a tea extraction device. When in use, first, tea leaves and an extracting liquid of a suitable temperature can be added into the interior of the extraction tank 1 through the liquid adding valve 3 and the feed port 4, so as to perform extraction. During extraction, the filter screen 12 plays a filtering role, so that the extracted tea juice enters the upper part of the diversion tank 2, and the tea leaves remain in the extraction tank 1;

[0028] After the extraction is completed, the external transmission pipeline can be connected to the drain valve pipe 11, so as to guide the extracted tea juice for subsequent processing. At the same time, after all the tea juice is discharged, because the telescopic rod of the electric telescopic rod 8 is connected to the push rod 10, and the push rod 10 is connected to the blocking plate 9, and the blocking plate 9 is stuck in the lower part of the extraction tank 1, the telescopic rod of the electric telescopic rod 8 can be extended to drive the blocking plate 9 away from the extraction tank 1, and then the tea leaves can slide from the blocking plate 9 into the lower part of the diversion tank 2;

[0029] At the same time, when the tea leaves are discharged, the slag discharge motor 14 can be started, and the slag discharge motor 14 drives the spiral auger 7 to rotate in the extraction tank 1, so as to facilitate the pushing down of the tea leaves stuck in the extraction tank 1, so as to improve the cleaning effect. The electric telescopic rod 8 is installed on the rotating rod 6, and when the spiral auger 7 rotates, the blocking plate 9 rotates with the spiral auger 7, so that the stuck tea leaves can be thrown off by the centrifugal force of the rotation, so as to further improve the cleaning efficiency.

[0030] At the same time, when extracting tea leaves, the driving shaft of the slag discharge motor 14 is reversed to drive the spiral auger 7 to reverse, so that the tea leaves deposited at the bottom can be transported upward, thereby preventing the tea leaves from piling up at the bottom and improving the uniformity of extraction. At the same time, the rotation of the spiral auger 7 plays a role in stirring and mixing, so as to improve the extraction efficiency.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
