Description

Technical Field

[0001] The utility model relates to the technical field of extraction tanks, in particular to a filter device for an anti-blocking extraction tank. Background Technique

[0002] An extraction tank is a commonly used leaching and extraction device in pharmaceutical and chemical industries, especially suitable for the leaching and extraction of components contained in plant products. It has a tank body, a screw propeller or a propeller arranged axially in the tank body, which is connected to a rotating shaft disk outside the tank. Its characteristic is that it has a group of obliquely lying continuous countercurrent leaching and extraction single tanks, and the discharge ports and feed ports are connected to each other to form a communicating vessel.

[0003] During the process of processing medicinal materials, a filter is usually required to filter and separate the medicinal materials and the medicinal liquid to ensure the effect of medicinal liquid extraction. For example, an energy-saving traditional Chinese medicine extraction tank proposed in Chinese Patent CN 204428888 U has a check valve provided on the pipeline between the metering water meter and the sprinkler head. The setting of the check valve can effectively prevent steam from entering the metering water meter through the sprinkler head during the heating process and causing damage to the metering water meter. The filter screen is fixed on the inner wall of the tank body by bolts, which is convenient for the disassembly and replacement of the filter screen, and replaces overall maintenance with partial maintenance, reducing the equipment maintenance cost. However, this design does not have the advantage of anti-blocking, resulting in the filter of the extraction tank being easily blocked during the process of extracting medicinal materials, making it difficult for the extraction tank to discharge materials. It also requires manual cleaning by staff, with a large labor intensity for the staff, thereby affecting the effect of the extraction tank in processing medicinal materials, being inconvenient to use, unable to meet the actual use requirements, and reducing the use efficiency and use effect of the extraction tank.

By setting four support feet, the extraction tank body 1 can be supported.

[0039] The working principle of the above embodiment is as follows:

[0040] (1) When the medicinal materials need to be processed, by rotating the four movable rotating blocks 20, the four movable screw rods 19 and the four movable clamping blocks 21 can be driven to rotate respectively. Since the four fixed screw frames 18 are respectively threadedly connected to the four movable screw rods 19, during the rotation of the four movable screw rods 19, the four movable clamping blocks 21 will rotate and move upward respectively, so that the four movable clamping blocks 21 are separated from the movable cover 17, and the movable cover 17 loses its limit, and the movable cover 17 can be disassembled from the top of the extraction tank body 1. Thus, the medicinal materials and the medicinal materials can be poured into the inside of the extraction tank body 1. Then, by the above principle, the movable cover 17 is placed above the extraction tank body 1, and by rotating the four movable rotating blocks 20 in the reverse direction, the four movable clamping blocks 21 can be driven to rotate and move downward respectively, so that the four movable clamping blocks 21 are all attached to the movable cover 17, and thus the movable cover 17 can be stably installed above the extraction tank body 1, avoiding the phenomenon that the movable cover 17 falls off during the processing of the medicinal materials in the extraction tank body 1.

[0041] (2) The heating electric plate 33 can be used to heat the medicinal materials and liquid medicine inside the extraction tank body 1. When the medicinal materials and liquid medicine need to be extracted, the medicinal materials and liquid medicine can be filtered and separated by the filter plate 8. The liquid medicine will flow through the filter holes to the inner bottom wall of the extraction tank body 1, and the medicinal materials will remain above the filter plate 8. By adjusting the fixed valve 31, the liquid medicine inside the extraction tank body 1 can be discharged through the liquid outlet pipe 30.

[0042] (3) By setting up the air blowing pump 9, gas can be blown into the inside of the extraction tank body 1 successively through the air blowing pipe 10, the first purifier 11 and the air inlet pipe 12. The inside of the extraction tank body 1 can be back-blown and pressurized. At the same time, by setting the solenoid valve 16, the connecting pipe 15 can be opened or closed regularly. Thus, the gas inside the extraction tank body 1 can be discharged successively through the air outlet pipe 14, the second purifier 13 and the connecting pipe 15, and the inside of the extraction tank body 1 can be depressurized. Therefore, by pressurizing and depressurizing the extraction tank body 1, the medicinal materials and the medicinal liquid can move inside the extraction tank body 1, the phenomenon of blockage of the filter plate 8 can be avoided, and the filtering and separating effect of the filter plate 8 on the medicinal materials and the medicinal liquid can be improved. The first purifier 11 and the second purifier 13 can prevent dust and particles from entering the inside of the extraction tank body 1 during the pressurization and depressurization processes of the extraction tank body 1, so as to ensure the processing effect of the extraction tank body 1 on the medicinal materials and the medicinal liquid.

[0043] (4) When it is necessary to clean the medicinal materials above the filter plate 8, first disassemble the movable cover 17 according to the above principle, and then the electric motor 4 can drive the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the threaded plate 6, during the rotation of the threaded rod 5, the threaded plate 6, the two adjusting rods 7 and the filter plate 8 will be driven to move upward in sequence. During the upward movement of the filter plate 8, the filter plate 8 can be moved out of the inside of the extraction tank body 1, so as to clean the medicinal materials above the filter plate 8.

[0044] (5) When it is necessary to disassemble, replace or clean the filter plate 8, first move the filter plate 8 out of the inside of the extraction tank body 1 according to the above principle, and then rotate the two manual turning handles 24 to drive the two screw rods 23 and the two limit clamping blocks 25 to rotate respectively. Since the two screw blocks 22 are threadedly connected to the two screw rods 23 respectively, during the rotation of the two screw rods 23, the two limit clamping blocks 25 restricted will move left and right respectively, and the two limit clamping blocks 25 can be separated from the two positioning square blocks 26 respectively, so that the two positioning square blocks 26 and the filter plate 8 lose their limits, and thus the filter plate 8 can be disassembled, replaced or cleaned to ensure the hygiene of the filter plate 8.

[0045] (6) According to the above principle, through the cooperative action among the two positioning square blocks 26, the two positioning square grooves, the two screw blocks 22, the two screw rods 23, the two manual turning handles 24 and the two limit clamping blocks 25, the filter plate 8 can be stably connected to the two adjusting rods 7, and the phenomenon of the filter plate 8 falling off during use can be avoided, so as to ensure the filtering and separating effect of the filter plate 8 on the medicinal materials and the medicinal liquid.

[0046] Compared with the prior art, the overall structure is simple and convenient to use, achieving the purpose of preventing the filter from being blocked, avoiding the blockage of the filter during the process of extracting medicinal materials by the extraction tank, making the discharge of the extraction tank simple, eliminating the need for manual cleaning by staff, reducing the labor intensity of the staff, ensuring the processing effect of the extraction tank on medicinal materials, meeting the actual use requirements, and improving the use efficiency and effect of the extraction tank.
