Description

Technical Field

[0001] The utility model relates to the field of filter cleaning, in particular to a filter cleaning device for oral solid preparations. Background Art

[0002] Oral solid preparations refer to drug dosage forms prepared in solid form (such as tablets, capsules, granules, etc.) for patients to take orally. Oral solid preparations are one of the most common and widely used drug dosage forms. Filters are devices used to remove suspended matter, solid particles or other impurities. Filter cleaning devices for oral solid preparations are usually used to clean and maintain filter equipment used in the production process of solid preparations.

[0003] Existing granulation equipment for oral solid preparations screens oral solid preparations through mounted filters. During the screening process, the mounted filters are used for a long time, which can easily lead to filter blockage and make production difficult. At the same time, the mounted filters are inconvenient to clean, which can easily lead to low cleaning efficiency.

[0004] Therefore, it is necessary to design a filter cleaning device for oral solid preparations that is easy to clean the filter, improves the cleaning efficiency, and improves the flushing effect. Utility Model Content

[0005] In order to overcome the shortcomings of existing oral solid preparation granulation equipment, such as the long use time of the mounted filter, which easily leads to filter clogging and difficulty in production, and the inconvenience of cleaning the mounted filter, which easily leads to low cleaning efficiency, the technical problem to be solved is: to provide a filter cleaning device for oral solid preparations that is easy to clean the filter, improve the cleaning efficiency and improve the flushing effect.

[0006] The technical solution is: a filter cleaning device for oral solid preparations, including a bracket, a cleaning barrel, a filter, a blocking block, a cleaning mechanism and a flushing mechanism. The upper part of the bracket is connected to the cleaning barrel, and the filter is detachably connected to the cleaning barrel. The left and right sides of the cleaning barrel are slidably connected with blocking blocks. The bracket is provided with a cleaning mechanism for cleaning dust on the filter, and the cleaning barrel is provided with a flushing mechanism for cleaning the filter.

[0007] As a preferred technical solution of the utility model, two front and rear limiting members are connected to the outer sides of the blocking blocks to prevent the blocking blocks from sliding out.

[0008] As a preferred technical solution of the utility model, the filter is made of polypropylene, is chemically inert, and can resist the erosion of drugs.

[0009] As a preferred technical solution of the utility model, the cleaning mechanism includes a motor, a rotating frame, a sliding frame and a spring. The motor is connected to the upper middle side of the bracket, the rotating frame is connected to the output shaft of the motor, the sliding frame is slidably connected to the rotating frame, and two left and right springs are connected between the sliding frame and the rotating frame; the sliding frame contacts the filter, the spring is squeezed, and the rotating frame is driven to rotate by the motor, thereby driving the sliding frame to rotate.

[0010] As a preferred technical solution of the utility model, the sliding frame is connected with bristles to facilitate dust cleaning.

[0011] As a preferred technical solution of the utility model, the flushing mechanism includes a sliding rod, a piston plate and a threaded tube. The upper part of the rotating frame is connected to the threaded tube, and the piston plate is connected to the threaded tube through a thread. The piston plate is slidably connected to the cleaning barrel. The left and right sides of the bottom of the piston plate are connected to sliding rods, and the sliding rods are slidably connected to the cleaning barrel. The threaded tube rotates to drive the piston plate to move upward, and then the water in the cleaning barrel is used to flush the filter.

[0012] The beneficial effects are as follows: 1. The utility model drives the rotating frame to rotate through the motor, and then drives the sliding frame to rotate. The bristles of the sliding frame clean the dust on the filter, thereby facilitating the cleaning of the filter, preventing the filter from being blocked, and improving the cleaning efficiency.

[0013] 2. The utility model starts the motor to drive the rotating frame to rotate, and at the same time drives the threaded tube to rotate, thereby driving the piston plate to move upward, and the slide rod moves upward, pushing the water in the cleaning barrel upward to rinse the filter, thereby repeatedly rinsing the filter and improving the rinsing effect.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0021] A filter cleaning device for oral solid dosage forms, such as Figure 1-Figure 5 As shown, it includes a bracket 1, a cleaning barrel 2, a filter 3, a blocking block 4, a cleaning mechanism 5 and a flushing mechanism 6. The cleaning barrel 2 is connected to the upper part of the bracket 1, and the filter 3 is detachably connected to the cleaning barrel 2. The filter 3 is made of polypropylene and is chemically inert. The left and right sides of the cleaning barrel 2 are slidably connected to the blocking blocks 4, and the outer sides of the blocking blocks 4 are connected to two front and rear limit members. The bracket 1 is provided with a cleaning mechanism 5 for cleaning dust on the filter 3, and the cleaning barrel 2 is provided with a flushing mechanism 6 for cleaning the filter 3.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the cleaning mechanism 5 includes a motor 51, a rotating frame 52, a sliding frame 53 and a spring 54. The motor 51 is connected to the upper middle side of the bracket 1, the rotating frame 52 is connected to the output shaft of the motor 51, the sliding frame 53 is slidably connected to the rotating frame 52, the sliding frame 53 is connected to bristles, and two left and right springs 54 are connected between the sliding frame 53 and the rotating frame 52.

[0023] like Figure 1 and Figure 5 As shown, the flushing mechanism 6 includes a slide rod 61, a piston plate 62 and a threaded tube 63. The upper part of the rotating frame 52 is connected to the threaded tube 63, and the piston plate 62 is threadedly connected to the threaded tube 63. The piston plate 62 is slidably connected to the cleaning barrel 2. The left and right sides of the bottom of the piston plate 62 are connected to the slide rod 61, and the slide rod 61 is slidably connected to the cleaning barrel 2.

[0024] When it is necessary to clean the filter 3 of the oral solid preparation, the device can be used. The blocking block 4 is pulled outward by hand to open it, and the filter 3 is placed on the cleaning bucket 2. The filter 3 is made of polypropylene. Then the blocking block 4 is pulled inward to reset and fix the filter 3. The limiting piece prevents the blocking block 4 from sliding out. Then the sliding frame 53 contacts the filter 3, the spring 54 is squeezed, and then the motor 51 on the bracket 1 is started. The rotating frame 52 is driven to rotate by the motor 51, and then the sliding frame 53 is driven to rotate. The bristles of the sliding frame 53 clean the dust on the filter 3, thereby facilitating the cleaning of the filter 3 and preventing the filter 3 from being blocked. The plug improves the cleaning efficiency. After the cleaning is completed, the motor 51 is turned off, the rotating frame 52 no longer rotates, and the spring 54 rebounds. When the bristles clean the dust on the filter 3, water is poured to rinse the filter 3, and the water will flow into the cleaning barrel 2. Starting the motor 51 to drive the rotating frame 52 to rotate will also drive the threaded tube 63 to rotate, thereby driving the piston plate 62 to move upward, and the slide rod 61 moves upward to push the water in the cleaning barrel 2 up to rinse the filter 3, thereby repeatedly rinsing the filter 3 to improve the rinsing effect. After the rinsing is completed, the motor 51 is turned off, and then the filter 3 is taken out by pulling the blocking block 4 outward to open it.
