By using a crushing motor and a crushing roller in combination, the material can be crushed so that the material can better contact the liquid, thereby improving the extraction efficiency of the equipment, and the material transfer plate and the material guide plate are used in combination, the material transfer plate can guide the crushed material into the top of the material guide plate, and the material guide plate can guide the material into the interior of the centrifugal barrel, so that the material can be reacted and extracted inside the centrifugal barrel, and the diverter plate and the nozzle are used in combination, so that the equipment can be infused and the guide plate can be cleaned, thereby improving the functionality of the equipment;

[0004] Although the above patent can separate the astragalus medicinal material residue and the astragalus extract, some astragalus extract may remain in the astragalus medicinal material residue after separation. If the astragalus polysaccharide extract remaining in the astragalus medicinal material residue after separation is not squeezed out, but directly disposed of with the astragalus medicinal material residue, it is easy to cause waste and reduce the yield of astragalus extract. With the sharp rise in the price of astragalus medicinal materials in recent years, reducing waste in the astragalus extraction process and improving extraction efficiency have become important issues that pharmaceutical companies need to solve. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a filter press device for extracting astragalus which can overcome the above problems or at least partially solve the above problems.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example 1

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A filter press device for extracting Astragalus membranaceus comprises a tank body 1, and also comprises: a filter disc 104 detachably connected to the tank body 1, wherein the filter disc 104 is provided with a plurality of filter holes 105 equidistantly around the circumference, a filter press chamber 101 is provided above the filter disc 104 in the tank body 1, and a storage chamber 102 is provided below the filter disc 104 in the tank body 1; a pressure disc 402 is connected to the tank body 1; a driving part is arranged on the tank body 1 and is used to drive the pressure disc 402 to move; an annular frame 404 is slidably connected to the storage chamber 102, wherein a push rod 405 corresponding to the filter hole 105 is fixedly connected to the annular frame 404, and a slide groove 406 communicating with the storage chamber 102 is provided on the tank body 1; a push rod 403, one end of which is fixedly connected to the pressure disc 402, and the other end passes through the slide groove 406 and is fixedly connected to the annular frame 404.

[0024] The driving part includes an electric telescopic rod 401 . A support frame 4 is fixedly connected to the tank body 1 . The electric telescopic rod 401 is fixedly installed on the support frame 4 . The pressure plate 402 is fixedly connected to the output end of the electric telescopic rod 401 .

[0025] When in use, first pour the astragalus medicinal material residue into the filter press chamber 101, then start the electric telescopic rod 401, the electric telescopic rod 401 pushes the pressure plate 402 to move downward, and at the same time, the annular frame 404 and the top rod 405 follow the pressure plate 402 to move downward synchronously through the push rod 403, so that the top rod 405 is separated from the filter hole 105, and then the filter plate 104 is opened, and the pressure plate 402 is pressed against the astragalus medicinal material residue, so that the astragalus extract inside the astragalus medicinal material residue is squeezed out and flows into the storage chamber 102 through the filter hole 105, and the squeezed astragalus medicinal material residue is blocked on the filter plate 104, so as to achieve the purpose of filtering the astragalus extract. At the same time, the pressure plate 402 repeatedly moves up and down in the filter press chamber 101, which not only improves the extraction effect of the astragalus medicinal material, but also improves the quality of the extracted polysaccharide.

[0026] Then, when the electric telescopic rod 401 drives the pressure plate 402 to move upward, the annular frame 404 and the push rod 405 move upward synchronously with the pressure plate 402 through the push rod 403, so that the push rod 405 is inserted into the filter hole 105, and then the astragalus medicinal material residue that blocks the filter hole 105 is cleaned, thereby achieving the effect of automatically unblocking the filter hole 105, preventing the filter hole 105 from being blocked and affecting the filtration of the extruded astragalus extract. Example 2

[0027] Reference Figure 3 , Figure 4 and Figure 6 A filter press device for extracting Astragalus is basically the same as Example 1. Furthermore, a support ring 103 is fixedly connected to the inner wall of the filter press chamber 101, and the filter disc 104 is detachably connected to the support ring 103 by a fixing bolt 106. An opening 5 connected to the storage chamber 102 is opened on the tank body 1, and the opening 5 corresponds to the fixing bolt 106.

[0028] Since the filter disc 104 is fixedly connected to the support ring 103 by the fixing bolts 106, when the astragalus extract in the astragalus medicinal material residue is squeezed out, it is necessary to clean the astragalus medicinal material residue blocked on the filter disc 104, which makes it convenient for the staff to remove the filter disc 104 with the help of tools, and then take the filter disc 104 out of the filter press chamber 101, so as to facilitate the staff to clean the astragalus medicinal material residue blocked on the filter disc 104. Example 3

[0029] Reference Figure 3 , Figure 4, a filter press device for extracting astragalus, which is basically the same as Example 1, and further includes an electric heating wire 2, which is fixedly installed on a filter disc 104; before the astragalus extract in the astragalus medicinal material residue is recovered by filter pressing, since the top rod 405 is inserted into the filter hole 105 in the initial state, the filter hole 105 on the filter disc 104 is closed, and then the astragalus medicinal material residue poured into the filter press cavity 101 is heated by the electric heating wire 2, thereby reducing the viscosity of the astragalus extract in the astragalus medicinal material residue, which is conducive to recovering the astragalus extract in the astragalus medicinal material residue by filter pressing. Example 4

[0030] Reference Figure 1 , Figure 4 A filter press device for extracting astragalus root extract is basically the same as Example 1. Furthermore, a discharge pipe 3 connected to a storage chamber 102 is fixedly connected to the bottom of the tank body 1, and a valve switch 301 is provided on the discharge pipe 3; the bottom inner wall of the storage chamber 102 is conical.

[0031] When the astragalus extract in the astragalus medicinal material residue is recovered by filter pressing and the astragalus extract stored in the storage chamber 102 needs to be taken out, the valve switch 301 on the discharge pipe 3 is opened to allow the astragalus extract to be discharged from the storage chamber 102 through the discharge pipe 3. Since the bottom inner wall of the storage chamber 102 is conical, it is more conducive to the astragalus extract to be discharged from the storage chamber 102 through the discharge pipe 3, effectively reducing the waste of the astragalus extract.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
