Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine production, and in particular to an anti-clogging structure for a traditional Chinese medicine extraction tank. Background Technology

[0002] Traditional Chinese medicine extraction tanks are the most crucial and commonly used extraction equipment in traditional Chinese medicine production, suitable for various processes such as decoction, soaking, and reflux. After extraction, the residue and extract need to be separated. During separation, the liquid is drained first, followed by the residue discharge valve. To facilitate gravity-driven residue discharge, the lower part of the tank is designed with an inverted cone shape. However, some residues are quite large, making them prone to blockage during discharge. Currently, this is mainly addressed by manual tamping with a long-handled pestle or by using compressed air to purge the residue. However, the former is more cumbersome, and the latter carries the risk of the residue hardening and clumping due to airflow, making it even more difficult to discharge. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this invention provides an anti-clogging structure for a traditional Chinese medicine extraction tank, which can effectively solve the problem of blockage caused by large pieces of medicinal residue.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A clog-prevention structure for a traditional Chinese medicine extraction tank, wherein the lower part of the extraction tank is a conical section, and a slag discharge pipe is connected to the bottom of the conical section. The clog-prevention structure is connected to the slag discharge pipe and includes a Y-shaped tee. The Y-shaped tee includes an upper connecting pipe and two lower discharge pipes. A shut-off valve is provided on the lower discharge pipe. A flange for connecting to the slag discharge pipe is provided at the opening of the upper connecting pipe. A stirring shaft is provided inside the upper connecting pipe. The lower end of the stirring shaft passes through the two lower discharge pipes and is connected to a drive motor. The upper end of the stirring shaft extends into the conical section through the slag discharge pipe. Several blades, which are double-edged blades, are connected at intervals on the stirring shaft.

[0006] Preferably, the blade is inclined upwards or downwards from one end to the other.

[0007] Preferably, the blade is inclined from one side to the other.

[0008] Preferably, the lateral tilt angle of the blade is 23-26 degrees.

[0009] The advantages of this utility model using the above-mentioned technical solution are as follows: The anti-clogging structure of the Chinese medicine extraction tank is designed with a Y-shaped tee and a stirring shaft with blades, which can, on the one hand, play a role in stirring and breaking up the dregs during the extraction process, thus helping to improve the extraction efficiency; on the other hand, when discharging the dregs after extraction, it can break up large pieces of dregs again to effectively avoid clogging.

[0010] In particular, the blades are tilted at both ends and sides, which allows them to more effectively cut the dregs above and guide the material downwards during the rotation of the stirring shaft, resulting in smoother material feeding. Attached Figure Description

Detailed Implementation

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-5 As shown in this embodiment, the anti-clogging structure of the herbal medicine extraction tank includes a conical section 1 at the bottom of the extraction tank, a slag discharge pipe 2 connected to the bottom of the conical section 1, and an anti-clogging structure 3 connected to the slag discharge pipe 2. The anti-clogging structure 3 includes a Y-shaped tee 31, which includes an upper connecting pipe 311 and two lower discharge pipes 312. The lower discharge pipes 312 are equipped with shut-off valves, which can be connected to the pipe openings. The upper connecting pipe 311 is equipped with a flange 32 for connecting to the slag discharge pipe 2 at its opening. A stirring shaft 33 is provided inside the upper connecting pipe 311. The lower end of the stirring shaft 33 passes through the two lower discharge pipes 312 and is connected to a drive motor 34. The upper end of the stirring shaft 33 extends into the conical section 1 through the slag discharge pipe 2. Several blades 35 are connected at intervals on the stirring shaft 33, which can be welded and fixed. The blades 35 are double-edged blades.

[0019] Working principle: The anti-clogging structure is connected to the slag discharge pipe via flange 34, and a sealing ring maintains a tight seal during connection. During extraction, the drive motor 34 can be activated as needed. The rotation of the drive motor 34 breaks up the settled slag to some extent, improving extraction efficiency. During slag discharge, the shut-off valve is opened and the drive motor 34 is activated. The rotation of the drive motor 34 not only stirs and promotes slag discharge but also cuts down large pieces of falling slag, preventing blockages and resulting in high slag discharge efficiency.

[0020] In one specific embodiment, such as Figure 3-4 As shown, the blade 35 is inclined upwards or downwards from one end to the other; as Figure 5 As shown, the blade 35 is inclined from one side to the other. Inclining the blade both end-facing and side-facing allows it to cut the dregs at a smoother angle with less effort during rotation.

[0021] In one specific embodiment, such as Figure 5 As shown, the lateral tilt angle of the blade 35 is 23-26 degrees.

[0022] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0023] Any aspects of this utility model not described in detail are known to those skilled in the art.
