Description

Technical Field

[0001] The invention relates to the technical field of plant essential oil production, in particular to a raw material crushing device for plant essential oil production. Background Art

[0002] In the process of extracting essential oils, the raw material crushing process is a crucial step. The main purpose of this process is to crush plant raw materials, such as petals, leaves, rhizomes, etc., into smaller particles or powders through physical methods, so that the subsequent extraction process can more effectively extract the essential oil components in the plant.

[0003] In the crushing process, various mechanical equipment, such as crushers, grinders, etc., are usually used. These equipment can crush the raw materials according to the predetermined particle size requirements. However, although modern mechanical technology is very advanced, there are still some challenges in actual operation. Due to the wide variety of sources and varieties of plant raw materials, their specifications, hardness and toughness often vary greatly. This makes the existing single crushing method seem incapable of handling these raw materials of different specifications. For those harder or tougher raw materials, a single crushing may not be able to completely crush them to the expected particle size, resulting in uneven particle size after crushing, and the presence of larger particles or fragments. This uneven crushing effect will have an adverse effect on the subsequent extraction process. During the extraction process, the smaller the raw material particles after crushing, the larger the contact area with the extraction solvent, and the higher the extraction efficiency. However, if there are larger particles or fragments, their contact area with the extraction solvent will be reduced, resulting in incomplete extraction, and the yield and quality of the essential oil will be affected.

[0004] In addition, broken particles of different sizes will also affect the fluidity and mixing uniformity during the extraction process. Larger particles tend to form accumulations in the extraction container, hindering the flow and diffusion of the solvent, resulting in reduced mass transfer efficiency during the extraction process. At the same time, particles of different sizes are difficult to achieve uniform distribution when mixed, further affecting the extraction effect.

[0005] Therefore, in order to improve the production efficiency and product quality of plant essential oils, the crushing process needs to be improved and optimized. Summary of the invention

[0006] In order to overcome the disadvantage that in the production of plant essential oils, a single crushing method cannot fully crush raw materials of different specifications, thereby affecting the subsequent essential oil extraction, the purpose of the present invention is to provide a raw material crushing device for plant essential oil production using multi-stage circulation crushing.

[0007] The technical solution is: a raw material crushing device for the production of plant essential oils, including a casing, a screen frame group, a first power source and a crushing box group. The casing is composed of a side plate and a bottom plate, and the side plate and the bottom plate are spliced ​​and fixed by bolts. An opening is opened on the upper part of the casing, and a feed channel is arranged at the corresponding position of the opening. The screen frame group is arranged in the casing and can dock with the feed channel. The crushing box group is fixed in the casing and is located below the screen frame group. The first power source provides power to the crushing box group, and also includes a conveyor belt and a disturbance roller. The disturbance roller is rotatably connected to the inner wall of the casing and is located above the screen frame group. The first power source can drive the disturbance roller to rotate. The conveyor belt is connected between adjacent crushing box groups. Raw materials of different diameters fall into the various levels of the crushing box group from the screen frame group respectively. After the raw materials are crushed by the crushing box groups at various levels, they are finely crushed through the conveyor belt.

[0008] As a further preferred scheme, the screen frame group consists of a first-level screen frame, a second-level screen frame and a third-level screen frame which are arranged in a stepped manner with decreasing heights. The apertures of the sieve holes opened in the first-level screen frame, the second-level screen frame and the third-level screen frame increase gradually. Disturbance rollers are configured corresponding to each level of the screen frame. The disturbance rollers are provided with disturbance levers, and the disturbance levers correspond to the corresponding sieve holes.

[0009] As a further preferred embodiment, the crushing box group consists of a primary crushing box, a secondary crushing box and a tertiary crushing box arranged in a stepped manner with increasing height. The primary crushing box, the secondary crushing box and the tertiary crushing box are respectively located below the primary screen frame, the secondary screen frame and the tertiary screen frame.

[0010] As a further preferred solution, the conveyor belt consists of a first belt and a second belt, the first belt is connected between the tertiary crushing box and the secondary crushing box, and the second belt is connected between the secondary crushing box and the primary crushing box.

[0011] As a further preferred solution, a sweeping rod is also included, which is rotatably connected to the inner wall of the casing and is located below the crushing box group.

[0012] As a further preferred solution, a straight groove rod is radially connected to the end of the sweeping rod, a turntable is connected to the end of the crushing shaft of the crushing box group, a cam is fixed at the eccentric part of the turntable, and the cam slides in the straight groove of the straight groove rod.

[0013] As a further preferred scheme, it also includes a second power source, a crank shaft and a universal shaft. The first-stage screen frame, the second-stage screen frame and the third-stage screen frame are respectively limited and slid in the casing. The crank shaft is rotatably connected to each screen frame. Adjacent crank shafts are transmitted through the universal shaft. The second power source is connected to the side of the casing, and the output shaft of the second power source is connected to the crank shaft.

[0014] As a further preferred solution, a cover plate is also included, which is connected to the upper part of the casing, and the cover plate is provided with an observation port, and the observation port is equipped with a screen.

[0015] The present invention has the following advantages: 1. A sieve frame group with increasing sieve hole diameters is provided to screen the plant essential oil raw materials according to their specifications, and then a crushing box group with decreasing crushing particle diameters is used to crush the raw materials of each level separately. The conveyor belt can guide and convey the raw materials with larger sizes after crushing, so that raw materials of different specifications can be crushed in a graded and refined manner, avoiding the problem of insufficient crushing in conventional single crushing, and efficiently and systematically crushing and guiding the raw materials of different specifications separately, thereby effectively improving the production efficiency and quality of the plant essential oil.

[0016] 2. A disturbance roller is provided to push the raw materials in the screen frame group to improve the passing rate of the raw materials and prevent the raw materials from clogging the screen frames at all levels. At the same time, the crank shaft continuously pushes each screen frame to make each screen frame continuously move back and forth laterally, thereby forming vibration and further improving the passing rate of the raw materials.

The conveyor belt 7 is connected between the adjacent crushing box groups 6. Specifically, the conveyor belt 7 is composed of a first belt 701 and a second belt 702. The first belt 701 is connected between the tertiary crushing box 603 and the secondary crushing box 602, and the second belt 702 is connected between the secondary crushing box 602 and the primary crushing box 601. Raw materials of different diameters are respectively dropped into the various levels of the crushing box group 6 by the screen frame group 3. After being crushed by the crushing box groups 6 at various levels, the raw materials are finely crushed by the conveyor belt 7.

[0028] like Figure 2 and Figure 3 As shown, the screen frame group 3 consists of a first-level screen frame 301, a second-level screen frame 302 and a third-level screen frame 303 which are arranged in a stepped manner with decreasing heights. The apertures of the sieve holes provided in the first-level screen frame 301, the second-level screen frame 302 and the third-level screen frame 303 increase gradually. A disturbance roller 5 is configured corresponding to each level of the screen frame. The disturbance roller 5 is provided with a disturbance lever, and the disturbance lever corresponds to the corresponding sieve hole.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the crushing box group 6 consists of a primary crushing box 601, a secondary crushing box 602 and a tertiary crushing box 603 arranged in a stepped manner with increasing heights. The primary crushing box 601, the secondary crushing box 602 and the tertiary crushing box 603 are respectively located below the primary screen frame 301, the secondary screen frame 302 and the tertiary screen frame 303.

[0030] like Figure 6 and Figure 7 As shown, it also includes a sweeping rod 8, which is rotatably connected to the inner wall of the casing 1 and is located below the crushing box group 6.

[0031] like Figure 8 As shown, it also includes a second power source 12, a crank shaft 13 and a universal shaft 14. The first-stage screen frame 301, the second-stage screen frame 302 and the third-stage screen frame 303 are respectively limited and slid in the casing 1. The crank shaft 13 is rotatably connected to each screen frame through a connecting rod. Adjacent crank shafts 13 are driven through the universal shaft 14. The second power source 12 is connected to the side of the casing 1, and the output shaft of the second power source 12 drives the rightmost crank shaft 13 through a coupling.

The cover plate 15 is provided with an observation port, through which the staff can instantly observe the situation inside the casing 1. The observation port is equipped with a screen to prevent debris from invading the casing 1.

[0033] The working principle of the embodiment of the present invention is as follows: after the first power source 4 is turned on, the first power source 4 drives the disturbance roller 5 above the three-stage screen frame 303 to rotate through the pulley group, and the adjacent disturbance rollers 5 are driven by the pulley group. At the same time, the first power source 4 drives the three-stage crushing box 603 to operate, and the adjacent crushing boxes are driven by the chain gear assembly. Then the second power source 12 is turned on to drive the crank shaft 13 to rotate continuously. The crank shaft 13 will drive each screen frame to slide back and forth horizontally, thereby forming high-speed vibration, improving the pass rate of raw materials, and introducing the raw materials for the production of plant essential oils into the casing 1 through the feed channel 2. Raw materials of different specifications will fall into the screen frame group 3. Under the action of the disturbance roller 5, the screen frames at each level screen the raw materials. The raw materials of the smallest size will fall from the first-stage screen frame 301, and the raw materials of medium size will fall from the second-stage screen frame 302.
