Technical Field

[0001] This utility model relates to the field of material filtration technology, and in particular to a raw material filter. Background Technology

[0002] In the pharmaceutical manufacturing process, it is often necessary to use a vacuum filter to filter the liquid medicine and remove impurities from it.

[0003] Chinese patent document CN215539043U discloses a vacuum filtration device for pharmaceutical filtration, including a vacuum pump. A connecting pipe is connected to one side of the vacuum pump near its top, and one end of the connecting pipe is connected to a vacuum filtration chamber. A support pipe is installed at the top of the vacuum filtration chamber, and a placement tube is installed at the top of the support pipe. Mounting platforms are installed on both sides of the outer surface of the placement tube. Slide rails are installed at the top of each of the two mounting platforms, and limit plates are installed at corresponding ends of each of the two slide rails. Slider blocks are slidably connected to the outer surfaces of both slide rails. A first cover plate and a second cover are respectively installed at the top of the two sliders. A fixing groove is formed at one end of the first cover plate, and a magnet is installed on the inner wall of one side of the fixing groove. Through the arrangement of components such as the mounting platforms, slide rails, sliders, first cover plate, and second cover plate, the problem of the cover plate needing to be completely separated from the top of the placement tube when opened, which easily leads to contamination of the bottom surface of the cover plate and affects the interior of the placement tube, can be effectively solved.

[0004] When the above-mentioned pharmaceutical filtration device is in use, the impurities filtered out are trapped inside the device, making it difficult to quickly remove the filter screen. This makes cleaning more troublesome for staff, increases the workload of staff, and reduces the usability and practicality of the device. Utility Model Content

Detailed Implementation

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a raw material filter, including a filter tank 1, a filtration mechanism 3, and an anti-clogging mechanism 4. A liquid guide hopper 2 is fixedly installed on the inner wall of the filter tank 1. The filtration mechanism 3 is located inside the filter tank 1 and includes a cylindrical collection box 301, a connecting frame 302, and a filter screen 303. The outer wall of the cylindrical collection box 301 is fitted to but not connected to the inner wall of the liquid guide hopper 2. A circular opening is provided at the bottom of the cylindrical collection box 301, and the filter screen 303 is embedded inside the circular opening. A fixed installation is provided at the top of the cylindrical collection box 301. A connecting frame 302 is provided; an anti-blocking mechanism 4 is set inside the filtration tank 1, the anti-blocking mechanism 4 includes a rotating rod 401 and a scraper 403, and two sets of scraper 403 are fixedly installed on the outer wall of the rotating rod 401; a sealing gasket is provided on the inner bottom of the liquid guide hopper 2; a feed inlet 8 is opened on the top of the filtration tank 1; a vacuum pump 5 is fixedly installed on the outer wall of the filtration tank 1, and a suction pipe 6 is fixedly installed on the input end of the vacuum pump 5, one end of the suction pipe 6 is fixedly connected to and communicates with the outer wall of the filtration tank 1; a drain pipe 7 is fixedly installed at the bottom of the filtration tank 1, and a valve is provided on the drain pipe 7.

[0024] Secondly, the filtration mechanism 3 also includes a positioning block 304, a threaded rod 305, and an auxiliary knob 306. A set of positioning blocks 304 are fixedly installed on both sides of the connecting frame 302. Two sets of threaded rods 305 are threadedly connected to the top of the filtration tank 1. One end of the threaded rod 305 extends into the interior of the filtration tank 1 and contacts the top of the positioning block 304. The other end of the threaded rod 305 is fixedly installed with an auxiliary knob 306. During filtration, impurities can be collected in the cylindrical collection box 301. After filtration, the cylindrical collection box 301 can be quickly removed, which is convenient for the staff to clean the filtered impurities in a concentrated manner, reducing the amount of work done by the staff and improving the usability and practicality of the device.

[0025] Furthermore, the anti-clogging mechanism 4 also includes a rotating rod 401. The rotating rod 401 is rotatably mounted on the top inner side of the connecting frame 302. One end of the rotating rod 401 passes through the connecting frame 302 and is fixedly mounted with a crank 402. The bottom of the scraper plate 403 is in contact with the top of the filter screen 303 but not connected. During the filtration process, the surface of the filter screen 303 is continuously swept to prevent the filter holes from being blocked by impurities. The operation is simple and easy to use, which improves the filtration efficiency of the device.

[0026] Working principle: When using this device, the cylindrical collection box 301 is placed into the filtration tank 1 through the feed inlet 8 and inserted into the liquid guide hopper 2. Then, the cylindrical collection box 301 is rotated, causing the positioning block 304 to move below the threaded rod 305. The threaded rod 305 is rotated by the auxiliary knob 306, causing it to move downwards, so that one end of the threaded rod 305 abuts against the positioning block 304, thereby pressing the cylindrical collection box 301 tightly into the liquid guide hopper 2. Then, the liquid to be filtered is poured into the filtration tank 1, and under the guidance of the liquid guide hopper 2, it converges into the cylindrical collection box 301. The vacuum is then activated. Pump 5 draws air from the filtration tank 1 through suction pipe 6, creating a negative pressure in the space below the liquid guide hopper 2. This allows the liquid medicine to flow quickly through the filter screen 303, while impurities in the liquid medicine are trapped in the cylindrical collection box 301. By rotating the rotating rod 401 through crank 402, the scraper 403 continuously sweeps across the filter screen 303, clearing away the accumulated impurities. After filtration, the valve on the drain pipe 7 is opened to discharge the filtered liquid medicine. Then, the cylindrical collection box 301 is removed from the filtration tank 1 through the connecting frame 302, and the filtered impurities are collected and cleaned.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
