Description

Technical Field

[0001] The utility model belongs to the technical field of traditional Chinese medicine extraction and relates to a pressing type continuous extraction device. Background Art

[0002] The compression extraction of Chinese medicine refers to a method of squeezing out the active ingredients in Chinese medicine using mechanical force. The existing traditional compression extraction devices have scattered processes, slow speed and low efficiency.

[0003] A pharmaceutical pressing type continuous Chinese medicine extraction device is disclosed in the patent document with the publication number CN114515443A, which includes a crushing roller group, an extraction tank, and a conveying assembly. An extrusion side plate and an extrusion bottom plate are provided in the extraction tank. The liquid medicine is squeezed out of the medicinal material. The herbal tissue can be squeezed and destroyed, which is more convenient for extraction. The problem of process dispersion is solved. However, in actual use, the liquid medicine will still remain in the medicinal residue after being squeezed by the extrusion side plate and the extrusion bottom plate, which reduces the utilization rate of the medicinal material raw materials.

[0004] For example, a pharmaceutical pressing type continuous Chinese medicine extraction device is disclosed in the patent document with publication number CN110918233A, which includes a raw material bin, a storage bin, a support tank, a pressing bin and a crushing motor, etc. The medicinal materials are initially crushed to increase the subsequent pressing speed of the medicinal materials, so that the pressing efficiency is higher.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example 1

[0036] like Figure 1-Figure 7 As shown, the technical solution adopted in this embodiment is as follows: a pressing type continuous extraction device includes a first box body 2, a second box body 11, a primary extrusion assembly and a secondary extrusion assembly. The primary extrusion assembly is arranged in the first box body 2, and the secondary extrusion assembly is arranged in the second box body 11. The second box body 11 is arranged on one side of the first box body 2, and the second box body 11 is connected to the first box body 2. Specifically, a slag discharge port is opened on one side of the first box body 2, and a guide plate 14 is fixedly connected to the lower side of the slag discharge port, and the end of the guide plate 14 facing away from the first box body 2 extends into the second box body 11. The guide plate 14 is arranged obliquely, and the end of the guide plate 14 close to the second box body 11 is inclined downward.

[0037] A feed hopper 1 is provided at the upper end of the first housing 2, and raw materials are added into the first housing 2 from the feed hopper 1. The primary extrusion assembly extrudes the raw materials entering the feed hopper 1. The primary extrusion assembly includes a first pressure roller 3 and a second pressure roller 6, and the first pressure roller 3 and the second pressure roller 6 are both rotatably mounted in the first housing 2. A driving assembly for driving the primary extrusion assembly is installed on the first housing 2. The driving assembly includes a motor 12, which is fixedly mounted on the first housing 2, and the motor shaft of the motor 12 is coaxially fixedly connected with the first pressure roller 3. One end of the first pressure roller 3 extends to the outside of the first housing 2 and is coaxially fixedly mounted with a first gear 4.

The first pressure roller 3 and the second pressure roller 6 are arranged in parallel, and the gap between the first pressure roller 3 and the second pressure roller 6 is directly opposite to the feed hopper 1. In this way, the raw material entering the first box body 2 falls between the first pressing roller 3 and the second pressing roller 6. As the first pressing roller 3 and the second pressing roller 6 rotate, the raw material moves downward from between the first pressing roller 3 and the second pressing roller 6 and is squeezed by the first pressing roller 3 and the second pressing roller 6.

[0038] A first filter screen 15 is disposed in the first box body 2. The first filter screen 15 is tilted, and one end of the first filter screen 15 close to the slag discharge port is tilted downward and fixedly connected to the guide plate 14. The first filter screen 15 is located below the primary extrusion assembly. A first discharge port 17 is disposed at the lower end of the first box body 2, and a first bottle body 8 is disposed below the first discharge port 17. A plurality of legs 7 are fixedly connected to the lower end of the first box body 2.

[0039] The raw material falls onto the first filter screen 15 after being squeezed by the primary squeeze assembly, and the liquid medicine therein flows into the first bottle body 8 through the first filter screen 15 for collection. The medicine residue enters the second box body 11 under the guidance of the first filter screen 15 and the guide plate 14.

[0040] Guide blocks 13 are provided on both sides of the first filter screen 15 near one end of the guide plate 14 to prevent the drug residues dropped from the primary extrusion assembly from gathering at a corner near the slag discharge port in the first box body 2.

[0041] A second filter screen 16 is disposed in the second box body 11 , a second discharge port 18 is disposed at the lower end of the second box body 11 , and a second bottle body 9 is disposed below the second discharge port 18 .

[0042] The secondary extrusion assembly includes a second pressing plate 27, which is disposed in the second box body 11 for horizontal reciprocating movement, and the second pressing plate 27 is linked with the primary extrusion assembly through a linkage assembly.

[0043] The linkage assembly includes a transmission belt 23, a connecting rod 20 and a connecting rod 22. A second pulley 25 is coaxially fixedly sleeved on the second pressure roller 6, a mounting plate 19 is fixedly connected to the second box body 11, a first pulley 21 is rotatably mounted on the mounting plate 19, and the first pulley 21 is located on the side of the mounting plate 19 away from the second box body 11. The transmission belt 23 is sleeved between the second pulley 25 and the first pulley 21. A rotating rod is rotatably mounted on the mounting plate 19, the first pulley 21 is coaxially fixedly connected to the rotating rod, and one end of the rotating rod extends to the side of the mounting plate 19 away from the first pulley 21.

[0044] Two second slide grooves 24 are symmetrically provided on the second box body 11. The connecting rod 22 includes a first connecting section and a second connecting section, the first connecting section is slidably arranged between the two second slide grooves 24, and the second pressure plate 27 is fixedly connected to the first connecting section. The second connecting section is vertically arranged outside the second box body 11, and the middle part of the second connecting section is fixedly connected to one end of the second connecting section. A first slide groove is provided on the second connecting section. A sliding column is slidably arranged in the first slide groove. One end of the connecting rod 20 is fixedly connected to the end of the rotating rod away from the first pulley 21, and the other end of the connecting rod 20 is rotatably connected to the sliding column.

[0045] The second box 11 is provided with a sliding opening, the second filter 16 is slidably matched with the sliding opening, and one end of the second filter 16 close to the sliding opening is fixedly connected with a connecting plate 10 for shielding the sliding opening. In this way, it is convenient to take out the medicine residue in the second box 11.

[0046] When in use, the raw material is put into the first box body 2 from the feed funnel 1, and after passing through the primary extrusion assembly, the raw material is squeezed into drug residue and drug solution and falls onto the first filter screen 15. After being filtered by the first filter screen 15, the drug solution flows into the first bottle body 8 after passing through the first filter screen 15. The drug residue remains on the first filter screen 15, and under the guidance of the first filter screen 15 and the guide plate 14, enters the second box body 11 and falls onto the second filter screen 16.

[0047] At the same time, the second pressing roller 6 drives the second pulley 25 to rotate. Under the action of the transmission belt 23, the first pulley 21 rotates, the connecting rod 20 drives the rotating rod to rotate, and the rotating rod drives the connecting rod 22 to slide back and forth along the second slide groove 24, and then the second pressing plate 27 moves back and forth to squeeze the medicinal residue entering the second box body 11, squeeze out the liquid medicine in the medicinal residue, and flow into the second bottle body 9. When the connecting rod 22 moves back and forth along the second slide groove 24, the end of the connecting rod 20 away from the rotating rod slides up and down in the first slide groove. The primary extrusion assembly drives the secondary extrusion assembly to work, which reduces the number of power sources used, is conducive to realizing the automation of the device, and improves work efficiency.

[0048] By pulling the connecting plate 10 , the second filter screen 16 can be pulled out from the second box body 11 , so as to facilitate cleaning of the medicine residue in the second box body 11 .

[0049] Example 2

[0050] This embodiment only introduces the parts that are different from Embodiment 1, and the rest of the parts are the same as Embodiment 1.

[0051] like Figure 6-Figure 9 As shown, in this embodiment, the secondary extrusion assembly includes a first pressing plate 26. A hydraulic rod 28 is fixedly mounted on the upper end of the second housing 11, and the output end of the hydraulic rod 28 vertically extends downward into the second housing 11 and is fixedly connected to the first pressing plate 26. Under the action of the hydraulic rod 28, the first pressing plate 26 moves up and down, and then performs secondary extrusion on the medicinal residue entering the second housing 11, so that the residual liquid medicine in the medicinal residue is squeezed out, and the squeezed liquid medicine falls into the second bottle 9 for collection. The large contact area between the first pressing plate 26 and the medicinal residue is conducive to improving the working efficiency of the squeezing.

[0052] The upper end surface of the first pressing plate 26 is inclined, and the end close to the first box body 2 is inclined downward. This is conducive to making the medicine residues falling on the first pressing plate 26 slide onto the second filter screen 16.
