Description

Technical Field

[0001] The present application relates to the technical field of waste grinding treatment, and in particular to a traditional Chinese medicine residue grinding device and a grinding treatment method thereof. Background Art

[0002] Traditional Chinese medicine waste residue refers to the biological tissues and organs that have not been developed and utilized in the processes of medicinal material production, decoction piece processing, traditional Chinese medicine extract preparation, etc. It is usually a mixture after extraction of the roots, stems, leaves of plants, animal residues, mineral medicines, etc. Traditional Chinese medicine waste residue is usually a wet material that is extremely easy to rot. If not treated in time and stacked for a long time, it is very easy to ferment and rot, and emit extremely pungent odors (especially in the hot summer season). Once it rains, the generated sewage will directly penetrate into the ground, affecting the domestic water and air quality of the surrounding residents, and at the same time restricting the processing and production of medicines. Therefore, the waste residue should be reasonably treated at any time.

[0003] After certain processing, the waste residue can be used as organic fertilizer, generally processed by special waste residue crushing equipment. However, the common waste residue crushing equipment on the market still has certain deficiencies when in use. First of all, it is difficult for the common waste residue crushing equipment to ensure the uniformity of the crushed waste residue, resulting in poor product effects when using the waste residue as organic fertilizer. Secondly, the crushed waste residue by the common waste residue crushing equipment is not convenient for long-term storage, and the collection operation is relatively cumbersome. For this reason, we have designed a traditional Chinese medicine residue grinding device and a grinding treatment method thereof to solve the above problems. Summary of the Invention

The refrigeration system, the vacuum system, and the heating system (not shown in the figure) are installed in the freeze-drying chamber 41 to perform sequential pre-freezing, vacuum pumping, and heat sublimation treatment on the remaining moisture in the ground medicinal residues, so as to process the medicinal residues into dry, porous, and brittle freeze-dried medicinal residues. Two groups of the second opening and closing assembly 42 are installed and are respectively arranged at the upper and lower openings of the freeze-drying chamber 41 to control the opening and closing of the upper and lower openings of the freeze-drying chamber 41.

[0026] Reference Figure 2 , Figure 3 and Figure 6 , the vibrating hammer grinding mechanism 5 includes a hammer grinding chamber 51, a hammer grinding cover 52, a hammer grinding assembly 53, a vibrating frame 54, a power assembly 55 and a third opening and closing assembly. The vibrating frame 54 is a circular ring-shaped frame body installed on the mounting plate 13 in the crushing box body 1 through a plurality of damping springs 9 and can be driven by the power assembly 55 to continuously vibrate in the crushing box body 1. The hammer grinding chamber 51 is fixedly installed on the vibrating frame 54 through bolts and has openings at both the top and bottom. Two hammer grinding covers 52 are installed and are symmetrically rotatably arranged at the top opening of the hammer grinding chamber 51 to control the connection between the hammer grinding chamber 51 and the freeze-drying chamber 41. The rotation of the hammer grinding cover 52 is driven by a micro motor installed in the hammer grinding chamber 51. A plurality of groups of the hammer grinding assembly 53 are installed and are respectively arranged on the two hammer grinding covers 52 to hammer and crush the freeze-dried medicinal residues entering the hammer grinding chamber 51. The third opening and closing assembly is installed at the bottom opening of the hammer grinding chamber 51 to control the opening and closing of the bottom opening of the hammer grinding chamber 51. In this embodiment, the third opening and closing assembly also uses a rotary opening and closing assembly that converts rotary motion into opening and closing motion or converts opening and closing motion into rotary motion, which is a prior art and will not be elaborated too much.

[0027] Further, the hammer grinding assembly 53 includes a high-frequency hammering gun 531 and a hammer head 532. The high-frequency hammering gun 531 is installed on the hammer grinding cover 52 and its gun head extends into the hammer grinding box 51. The hammer head 532 is sleeved on the gun head of the high-frequency hammering gun 531. The hammer head 532 is frustum-shaped and the end facing away from the high-frequency hammering gun 531 is the large-area end.

The end face area formed by the end faces of multiple hammer heads 532 facing away from the high-frequency hammering gun 531 is equal to the horizontal cross-sectional area of the hammer grinding box 51. The height of the hammer grinding box 51 is at least three times the height of the hammer head 532, thereby ensuring that the hammer grinding assembly 53 can hammer the medicinal residues at any position in the hammer grinding box 51. When the hammer grinding assembly 53 is not working, the hammer head 532 is embedded in the hammer grinding cover 52. The hammer grinding time of the hammer grinding assembly 53 is set according to pre-tested data to ensure that the freeze-dried medicinal residues can be completely pulverized. This is prior art and will not be elaborated too much.

[0028] Further, the power assembly 55 includes multiple vibration motors. The multiple vibration motors are evenly arranged at intervals in the circumferential direction around the vibration frame 54 on the side wall of the vibration frame 54 facing away from the mounting plate 13, thereby driving the vibration frame 54, the hammer grinding box 51, and the medicinal residue material in the hammer grinding box 51 to continuously vibrate and disperse through the multiple vibration motors, and thus making the grinding of the freeze-dried medicinal residues into powder more efficient and uniform.

The brush body 623 is installed at the bottom of the outer frame body 621 for scraping the fine screen 61. When the hammer grinding of the freeze-dried medicinal residues in the vibration hammer grinding mechanism 5 is completed, the third opening and closing assembly opens, and the medicinal residue powder falls onto the fine screen 61. Part of the medicinal residue powder smaller than or equal to the pores of the fine screen 61 directly passes through the fine screen 61 and falls to the bottom of the crushing box body 1; the remaining medicinal residue powder that cannot pass through the fine screen 61 is cut at high speed by the cutting screen 622 so that the remaining powder reaches the passing size of the fine screen 61, and the brush body 623 at the bottom of the outer frame body 621 can continuously scrape the fine screen 61 to avoid the possibility of the fine screen 61 being blocked due to dust accumulation.

[0031] Refer to [[ID=)) Figure 1 and Figure 2 , a control unit 10 is also installed on the outer wall of the crushing box body 1. The control unit 10 is electrically connected to the drying mechanism 2, the grinding mechanism 3, the freeze-drying mechanism 4, the vibration hammer grinding mechanism 5 and the secondary fine grinding and screening mechanism 6 to control the operation of the electrical components in each mechanism. In a feasible embodiment, the control unit 10 can adopt a PLC controller or an MCU control unit 10, and both are preset with a system and sensors for controlling each electrical component, so as to ensure the sequential and timed operation of each mechanism. This is prior art and will not be elaborated too much.

[0032] Further, the principle of the suction assembly 7 is the same as that of a vacuum cleaner, so as to continuously suck the medicinal residue powder screened from the fine screen 61 into the collection box 14 for storage. The whole collection process is clean and efficient, and thus can be stored for a long time.

[0033] The present invention also provides a method for grinding and processing traditional Chinese medicine medicinal residues. The medicinal residues are crushed and collected by the above-mentioned traditional Chinese medicine medicinal residue grinding device, and the method includes the following steps: Step 1: Pass the traditional Chinese medicine waste residue into the drying mechanism 2 through the feed inlet 11 of the crushing box body 1; Step 2: The drying mechanism 2 performs low-temperature drying on the traditional Chinese medicine waste residue to remove part of the moisture; Step 3: The dried waste residue is passed into the grinding mechanism 3 for cutting treatment; Step 4: The cut medicinal residues are sent to the freeze-drying mechanism 4 for freeze-drying treatment to generate dry, porous and brittle freeze-dried medicinal residues; Step 5: The freeze-dried medicinal residues are passed into the vibration hammer grinding mechanism 5 for hammer grinding and crushing treatment; Step Six: Some of the freeze-dried powder of the crushed medicinal residues directly falls into the bottom of the crushing box body 1 through the fine screen 61, and the remaining freeze-dried powder of the medicinal residues is dispersed and crushed by the secondary fine grinding and screening mechanism 6 and then falls into the bottom of the crushing box body 1 through the fine screen 61; Step Seven: The crushed traditional Chinese medicine residues are sent into the collection box 14 through the suction assembly 7 for storage and collection.
