Description

Technical Field

[0001] The utility model relates to the technical field of production of traditional Chinese medicine biological fertilizer, in particular to a multi-stage separation device for traditional Chinese medicine residues used in the production of biological fertilizer. Background Art

[0002] Traditional Chinese medicine biological fertilizer uses traditional Chinese medicine extracts as a carrier, and adds a variety of beneficial microorganisms, plant proteins, amino acids, trace elements, small molecule peptides, etc. It can be quickly absorbed by plants and promote growth. Traditional Chinese medicine biological fertilizer is rich in a variety of beneficial bacteria. It grows and reproduces in the rhizosphere of plants to become the dominant bacteria in the rhizosphere of crops, competing with harmful bacteria in the soil for nutrients, forming antagonism, and can effectively enhance crop resistance and prevent and control a variety of diseases and pests.

[0003] During the production process of traditional Chinese medicine biological fertilizer, it is necessary to extract the fermentation liquid of the traditional Chinese medicine. During the extraction process, traditional Chinese medicine residue will be produced, and it is necessary to separate the traditional Chinese medicine residue and the fermentation liquid. The traditional way is to set a filter plate in the fermentation tank, place the traditional Chinese medicine on the filter plate for fermentation, and the produced fermentation liquid can flow into the fermentation liquid collection bucket under the filter plate through the filter plate, isolate the traditional Chinese medicine residue on the filter net, and directly realize solid-liquid separation; although this structure can directly separate the residue and the fermentation liquid, the residual residue will still contain traditional Chinese medicine components, causing waste. Therefore, on the basis of this scheme, an extrusion mechanism is added, and the traditional Chinese medicine residue is squeezed from above the filter plate through the extrusion plate to squeeze out the residual fermentation liquid in the traditional Chinese medicine residue, thereby improving the extraction rate.

[0004] However, in actual use, it was found that during the extrusion process, some smaller Chinese medicine residues were subjected to the pressure of the extrusion plate and sometimes got stuck on the filter or even passed through the filter, causing the extracted fermentation liquid to be impure and difficulty in cleaning the filter.

[0005] Therefore, the utility model provides a multi-stage separation device for Chinese medicinal residues used in the production of biological fertilizer to solve the above problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a multi-stage separation device for Chinese medicinal residues for the production of biological fertilizer, so as to solve the problem that the above-mentioned medicinal residues sometimes get stuck on the filter screen or even pass through the filter screen, causing the extracted fermentation liquid to be impure and making it difficult to clean the filter screen.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A multi-stage separation device for Chinese medicinal residues for the production of biological fertilizers comprises a fermentation tank, wherein a fermentation barrel and an extrusion plate are arranged inside the fermentation tank, the fermentation barrel is arranged to rotate in the horizontal direction and is provided with a rotation control mechanism, a first filter screen is arranged on the side wall of the fermentation barrel, a medicinal residue collection barrel is arranged outside the fermentation barrel, the medicinal residue collection barrel is provided with a residue discharge pipe, and a second filter screen is arranged on the bottom wall, a fermentation liquid collection barrel is arranged below the medicinal residue collection barrel, and the fermentation liquid collection barrel is provided with a liquid discharge pipe.

[0009] Preferably, a rotating support plate is provided in the fermentation tank, the fermentation barrel is rotatably connected to the rotating support plate, the rotation control mechanism is arranged above the support plate, and the height of the first filter screen is lower than the support plate.

[0010] Preferably, the rotation control mechanism includes a control motor and a gear connected to the control motor, and a gear ring meshing with the gear is provided on the circumference of the fermentation barrel.

[0011] Preferably, the top of the drug residue collecting barrel is fixedly connected to the rotating support plate.

[0012] Preferably, the fermentation tank is cylindrical.

[0013] Preferably, the medicinal residue collecting barrel is cylindrical, a residue cleaning plate is provided at the bottom of the fermentation barrel, and the residue discharge pipe is along the tangent direction of the medicinal residue collecting barrel.

[0014] Preferably, a slag cleaning brush is provided on the peripheral side of the extrusion plate.

[0015] Preferably, a feed pipe is slidably provided on the fermentation tank, and one end of the feed pipe can slide to the top of the fermentation barrel.

[0016] The beneficial effects of the utility model are:

[0017] 1. In the utility model, a first filter screen is arranged on the side wall of the fermentation barrel. When the Chinese medicine residue in the fermentation barrel is squeezed by the squeezing plate, the first filter screen is not subjected to force, and the fermentation liquid in the residue can be squeezed out smoothly, and the residue can be effectively prevented from being stuck on the first filter screen during the squeezing process.

[0018] 2. The rotating arrangement of the fermentation barrel in the utility model can play a certain stirring role and ensure the fermentation effect. During the rotation process, the centrifugal force is limited, and the drug residue is not easy to get stuck or pass through the first filter. Even if there is a tiny drug residue that is forced to pass through the first filter, it will fall into the drug residue collection barrel and be isolated by the second filter, thereby ensuring the purity of the fermentation liquid collected in the fermentation liquid collection barrel.

DETAILED DESCRIPTION

[0024] The following will refer to the attached Figures 1 to 4 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0025] like Figure 1 , Figure 2 , Figure 4 As shown, a multi-stage separation device for Chinese medicinal residues used in the production of biological fertilizer includes a fermentation tank 20. The fermentation tank 20 can control temperature, pressure, oxygen, etc. The fermentation tank 20 is provided with an exhaust hole, an oxygen generator, a heating device 11, etc., and a control panel 22 is provided on the outside of the fermentation tank for observing and adjusting the internal environment of the fermentation tank for fermentation. This part is the existing technology and will not be elaborated here.

[0026] A fermentation barrel 17 and an extrusion plate 3 are provided in the fermentation tank 20. The top of the fermentation barrel 17 is open, and the extrusion plate 3 is adapted to the inner wall of the fermentation barrel 17. The fermentation barrel 17 is used to place fermented Chinese medicine. Specifically, a movable or detachable cover body 1 is provided on the top of the fermentation tube 20, and a telescopic cylinder 2 is provided under the cover body 1. The cover body 1 is arranged at the lower end of the telescopic cylinder 2. By controlling the movement of the telescopic cylinder 2, the extrusion plate 3 is driven to extend into the fermentation barrel 17 and close to the bottom of the fermentation barrel 17, so that extrusion can be achieved.

[0027] The fermentation barrel 17 is arranged to rotate in the horizontal direction, and is provided with a rotation control mechanism, which can control the forward and reverse rotation of the fermentation barrel 17, and has a certain stirring effect on the inside of the fermentation barrel 17, which is conducive to the fermentation. The side wall of the fermentation barrel 17 is provided with a first filter 16, and the first filter 16 is used to pass the fermentation liquid and isolate the medicinal residue. Moreover, since the first filter 16 is arranged on the side wall, when the extrusion plate 3 is extruded, the Chinese medicine will not generate pressure on the first filter 16, and can be extruded more fully, and the medicinal residue will not be stuck on the first filter 16 or pass through. A first filter screen 16 and a medicinal residue collection barrel 15 are arranged outside the fermentation barrel 17. The medicinal residue collection barrel 15 is provided with a residue discharge pipe 9 and a valve, and a second filter screen 13 is arranged on the bottom wall. The medicinal residue can be filtered again through the second filter screen 13. When the fermentation barrel 17 rotates, the Chinese medicine will generate centrifugal force. Even if the fine medicinal residue passes through the first filter screen 16 due to the centrifugal force, it can be isolated through the second filter screen 14. A fermentation liquid collection barrel 12 is arranged below the medicinal residue collection barrel 15. The fermentation liquid collection barrel 12 is provided with a liquid discharge pipe 10 and a valve.

[0028] When the utility model is used specifically, the cover body 1 is first opened, and the Chinese medicine to be fermented is placed in the fermentation barrel 17, and then the cover body 1 is closed, and the internal environment of the fermentation tank 20 is controlled by the control panel 22 to ferment. During the fermentation process, the fermentation barrel 17 can be controlled by the control mechanism to rotate forward and reversely to promote fermentation, and the generated fermentation liquid falls into the medicine residue collection barrel 15 through the first filter screen 16, and passes through the second filter screen 13 again, and finally falls into the fermentation liquid collection barrel 12, completing the first collection, and then the medicine residue in the fermentation barrel 17 is squeezed by controlling the squeezing plate 3 to squeeze out the residual fermentation liquid. The remaining fermentation liquid passes through the first filter screen 16 and falls into the medicinal residue collection barrel 15, and passes through the second filter screen 13 again, and finally falls into the fermentation liquid collection barrel 12 to complete the second collection. During this process, the fermentation barrel 17 can keep rotating to assist in throwing out the fermentation liquid. After the medicinal residue is squeezed, smaller medicinal residue will be produced, and it may pass through the first filter screen 16 due to the centrifugal force. Even if it passes through the first filter screen 16, it will fall on the second filter screen 13; finally, the two layers of medicinal residue and fermentation liquid can be taken out separately; the utility model has a high extraction rate and the obtained fermentation liquid has few impurities.

[0029] In this embodiment, a rotating support plate 8 is provided in the fermentation tank 20. Specifically, the rotating support plate 8 is provided with a through-hole handle and a bearing. The fermentation barrel 17 is rotatably connected to the rotating support plate 8 through the bearing. The rotation control mechanism is arranged above the support plate 8. Specifically, the rotation control mechanism includes a control motor 6 and a gear 7 connected to the control motor 6. A gear ring 21 meshing with the gear 7 is provided on the periphery of the fermentation barrel 17. A connecting plate 5 is provided between the control motor 6 and the fermentation tank 20 to control the rotation of the fermentation barrel 17. The height of the first filter screen 16 is lower than the support plate 8. The top of the drug residue collection barrel 15 is fixedly connected to the rotating support plate 8 to ensure that the fermentation liquid passes through the first filter screen 16 smoothly into the drug residue collection barrel 15.

[0030] like Figure 3 As shown, in this embodiment, the fermentation tank 17 is cylindrical, the residue collecting barrel 15 is cylindrical, a residue cleaning plate 14 is provided at the bottom of the fermentation barrel 17, and the residue discharge pipe 9 is along the tangent direction of the residue collecting barrel 15. When taking out the residue fallen on the second filter screen 13, the fermentation barrel 17 can be controlled to rotate, thereby driving the residue cleaning plate 14 to clean the second filter screen 13. The residue is pushed by the residue cleaning plate 14 and is affected by the centrifugal force. When passing through the residue discharge pipe 9, it can enter the residue discharge pipe 9 and be thrown out.

[0031] In this embodiment, a slag cleaning brush 4 is provided on the side of the extrusion plate 3. Through the up and down movement of the extrusion plate 3, the slag cleaning brush 4 can play a certain cleaning role on the first filter screen 16. Even if there are residual medicine residues on the first filter screen 16, they can be cleaned in time by the slag cleaning brush 4.

[0032] In this embodiment, a sealing sliding member 19 on the fermentation tank 20 is slidably provided with a feed pipe 18 and a valve. One end of the feed pipe 18 can be slid to the top of the fermentation barrel 17. When the extrusion plate 3 is not in use, the feed pipe 18 can be slid for feeding. When the extrusion plate 3 is in use, the feed pipe 18 is slid out for use. There is no need to repeatedly open the cover body 1, and the operation is convenient.
