Description

Technical Field

[0001] This utility model relates to the field of gastric-soluble tablet coating production technology, and in particular to an exhaust device for gastric-soluble tablet coating production. Background Technology

[0002] Many drugs are formulated into stomach-coated tablets for easy transport and swallowing. To improve the patient's experience when swallowing, the tablets are coated to isolate the tablet's own taste and effectively isolate it from the external environment, extending its shelf life. During the tablet coating process, it is often necessary to maintain a constant temperature and sterile environment in the workshop. At this time, it is necessary to control the hot air to dry the coating, and use an exhaust system to remove the moisture generated during the coating process, keeping the equipment dry and clean, and ensuring the coating effect of the tablets.

[0003] The exhaust system used in the production of gastric-soluble tablets typically has an internal water collection tray to collect water generated during exhaust. The water in the tray often cannot be drained in time, which may cause damage to the internal parts of the equipment over time. In addition, when the exhaust system draws in air, it is easy for impurities to be carried and adhere to the filter screen at the air inlet, which requires regular cleaning, which is time-consuming and laborious. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing an exhaust device for the production of gastric-soluble tablet coating.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an exhaust device for the production of gastric-soluble tablet coating, comprising a coating device body, an air outlet fixed to the bottom of one side of the coating device body, an air inlet box fixed to the top of the other side of the coating device body, a dust filter fixedly installed on the outer wall of the air outlet, and a water outlet pipe fixedly installed at the bottom of the coating device body; further comprising:

[0006] The internal water absorption assembly includes a filter element pull plate that is snapped into the body of the coating device, three layers of filter elements that are fixedly installed inside the filter element pull plate, and a water drop trough opened at the bottom of the body of the coating device.

[0007] A cleaning structure, located inside the air outlet, is used to clean impurities remaining on the outside of the dust filter.

[0008] Furthermore, the cleaning structure includes a servo motor fixedly installed inside the air inlet box, a scraper blade rotatably connected to the outer wall of the dust filter, a mounting bolt threaded to the output shaft of the servo motor, a collection groove engaged with the bottom of the outer wall of the air inlet box, and a dust removal baffle engaged with the inside of the collection groove.

[0009] Furthermore, the shaft at the output end of the servo motor extends to the outside of the dust filter and is rotatably connected to the dust filter.

[0010] Furthermore, the scraper blade abuts against the outer wall of the dust filter screen, and the scraper blade is threadedly connected to the mounting bolt.

[0011] Furthermore, one end of the mounting bolt abuts against the dust collector baffle.

[0012] Furthermore, a handle is fixed on the outer wall of the filter element pull plate, and the water drop trough is inverted conical in shape.

[0013] Furthermore, the bottom ends of the water outlet pipe and the water trough are fixedly connected.

[0014] The beneficial effects of this utility model are as follows: By setting an internal water absorption component, excess water inside the coating device body is guided to the filter element pull plate and then filtered and absorbed by the three layers of filter elements inside the filter element pull plate. Finally, it is discharged in time through the water drop trough and the water outlet pipe, avoiding water accumulation in the coating device body for a long time and preventing damage to other components inside the coating device body; by setting a cleaning structure, when the air enters the air inlet box and the coating device body through the dust removal filter, the servo motor drives the scraper to scrape the surface of the dust removal filter. The scraped dust will fall into the collection trough through the dust removal baffle in the collection trough, ensuring that the surface of the dust removal filter remains unobstructed and saving manpower to clean the dust removal filter.

[0021] The accompanying drawings in this utility model are all schematic diagrams and their sizes do not represent actual dimensions.

[0022] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figures 1-5 As shown, an exhaust device for the production of gastric-soluble tablet coating includes a coating device body 1, an air outlet 2 fixed to the bottom of one side of the coating device body 1, an air inlet box 3 fixed to the top of the other side of the coating device body 1, a dust removal filter 4 fixedly installed on the outer wall of the air outlet 2, and a water outlet pipe 6 fixedly installed at the bottom of the coating device body 1.

[0025] It also includes: a cleaning structure 5 and an internal water absorption component 7. The internal water absorption component 7 is located at the bottom of the coating device body 1 near the air outlet 2 and is used to guide and discharge the accumulated water inside the coating device body 1 in a timely manner. The cleaning structure 5 is located inside the air outlet 2 and is used to clean the impurities remaining on the outside of the dust removal filter 4.

[0026] The cleaning structure 5 draws air into the air inlet box 3 from the outside of the dust filter 4. Before the air enters, it leaves impurities and dust in the air on the surface of the dust filter 4. At this time, the cleaning structure 5 can also clean the dust filter 4 on the outer wall of the dust filter 4. During the coating process, the exhaust gas will carry some liquid and some impurities. At this time, the liquid is filtered by the internal water suction component 7 and discharged from the water outlet pipe 6 to ensure that the inside of the coating device body 1 is clean.

[0027] The internal water absorption assembly 7 includes a filter element pull plate 701 that is snapped into the inside of the coating device body 1, a three-layer filter element 702 that is fixedly installed inside the filter element pull plate 701, and a water drop trough 703 that is opened at the bottom of the coating device body 1. A handle is fixed on the outer side wall of the filter element pull plate 701. The water drop trough 703 is inverted conical in shape. The water outlet pipe 6 is fixedly connected to the bottom end of the water drop trough 703.

[0028] Some of the liquid contained in the coating solution will be discharged through the exhaust device. At this time, the three-layer filter element 702 in the filter element pull plate 701 can absorb and trap some impurities in the gas, so that the liquid can be discharged smoothly from the water outlet pipe 6 at the bottom of the water tank 703, so that the waste liquid will not stay in the coating device body 1 for a long time and cause damage to other parts.

[0029] The cleaning structure 5 includes a servo motor 501 fixedly installed inside the air inlet box 3, a scraper 502 rotatably connected to the outer wall of the dust filter 4, a mounting bolt 503 threadedly connected to the output shaft of the servo motor 501, a collection groove 504 snapped into the bottom of the outer wall of the air inlet box 3, and a dust baffle 505 snapped into the collection groove 504. The output shaft of the servo motor 501 extends to the outside of the dust filter 4 and is rotatably connected to the dust filter 4. The scraper 502 abuts against the outer wall of the dust filter 4. The scraper 502 is threadedly connected to the mounting bolt 503. One end of the mounting bolt 503 abuts against the dust baffle 505.

[0030] The servo motor 501 is started, allowing air to enter from the outside of the dust filter 4. At the same time, the servo motor 501 drives the scraper 502, which is fixed to the output shaft of the servo motor 501 by the mounting bolt 503, to clean the outer wall of the dust filter 4. Since the mounting bolt 503 and the dust baffle 505 are in contact, when the scraper 502 rotates, the dust baffle 505 can collect the dust on the dust filter 4 into the collection groove 504 when it comes into contact with the mounting bolt 503, reducing the cleaning steps for the operator.

[0031] When this utility model is in use, after the dust on the surface of the dust removal filter screen 4 is swept away by the scraper 502 driven by the servo motor 501, it can be collected in the collection tank 504 through the collision between the scraper 502 and the dust removal baffle 505. This ensures that the surface of the dust removal filter screen 4 can be kept clean each time the coating device body 1 works, reducing the possibility of the surface of the dust removal filter screen 4 being blocked by dust. In addition, the waste liquid of the coating liquid in the coating device body 1 can be filtered and absorbed once through the three-layer filter element 702 in the filter element pull plate 701, and then discharged in time from the water outlet pipe 6 through the water drop trough 703, reducing the time that the waste liquid remains in the coating device body 1 and ensuring the cleanliness of the inside of the coating device body 1.

[0032] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
