Description

Technical Field

[0001] This utility model relates to the technical field of drug granulation and screening device structure, and in particular to a multi-level screen fixing frame for a drug granulation and screening device. Background Technology

[0002] Drug granulation and screening equipment includes devices for screening potassium chloride granules. Such equipment typically includes a main body, screening device, inlet, and outlet. The screening device contains a screen or filter belt, which is driven by vibration, electricity, or rollers to move, causing the potassium chloride granules to separate and be screened. Different particle sizes of potassium chloride granules are discharged from different outlets, thus achieving graded screening. The multi-level screen fixing frame is a key component of the drug granulation and screening equipment, used to support and fix the different levels of potassium chloride granule screens to achieve multi-level screening.

[0003] The function of the screen fixing frame is to stably support these screens that filter potassium chloride particles, ensuring the stability and screening efficiency of the potassium chloride particle screens during the screening process. In the existing technology, the multi-level screen fixing frame of the drug granulation screening device is one of the key components to ensure the normal operation of the device and achieve efficient screening. It forms a multi-level support structure through welding or bolt connection. This method of fixing the screens for filtering potassium chloride particles has several problems. First, when the potassium chloride particle screen needs to be inspected, cleaned and replaced, it is necessary to unscrew the welds and remove the bolts, which is inconvenient for disassembling and assembling the potassium chloride particle screen. Second, there is no structure to increase the vibration amplitude of the potassium chloride particle screen. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, a multi-level screen fixing frame for a drug granulation screening device includes three support tubes 1. Concave rings 2 are embedded and fixedly installed at the middle and both ends of the support tubes 1. Limiting structures 3 are fixedly installed on the rear surface of the support tubes 1 corresponding to the positions of the concave rings 2. A screen outer frame 4 is clamped between the limiting structures 3. Six auxiliary legs 5 are fixedly installed on the lower surface of the lowest concave ring 2. The auxiliary legs 5 are evenly distributed on the lower surface of the lowest concave ring 2. Potassium chloride granule screens of different mesh sizes are laid and fixed on the upper surface of the screen outer frame 4.

[0023] In this embodiment, the limiting structure 3 includes a limiting strip 301, a limiting slide bar 302, a J-shaped clamp 303, a first spring 304, a handle 305, and an L-shaped pin 306.

[0024] In this embodiment, the limiting strip 301 is fixedly installed on the rear surface of the support tube 1 near the circular through hole. The upper surface of the limiting strip 301 has a circular through hole, and there are three circular through holes on the upper surface of the limiting strip 301.

[0025] In this embodiment, the limiting slide bar 302 is disposed in the circular through hole of the limiting plate 301, the J-shaped clamp 303 is fixedly installed at the front end of the limiting slide bar 302, the first spring 304 is sleeved on the outside of the limiting slide bar 302, the front end of the first spring 304 is fixedly connected to the support tube 1, the rear end of the first spring 304 is fixedly connected to the rear end of the limiting slide bar 302, the J-shaped clamp 303 is located in the rectangular through hole of the support tube 1, and the outer side of the screen frame 4 is inserted into the interior of the J-shaped clamp 303.

[0026] In this embodiment, the handle 305 is fixedly installed at the rear end of the limiting slide bar 302, and the L-shaped pin 306 is disposed in the through hole at the rear end of the limiting slide bar 302. The lower end of the L-shaped pin 306 is inserted into the circular through hole on the upper surface of the limiting plate 301. When the screen frame 4 is to be removed, pull the L-shaped pin 306 upward and pull the handle 305 until the lower end of the L-shaped pin 306 is aligned with the circular through hole in the middle of the upper surface of the limiting plate 301. Then, the L-shaped pin 306 is inserted into the circular through hole on the upper surface of the limiting plate 301, and the screen frame 4 can be removed from between the J-shaped clamps 303. When removing one layer of screen frame 4, pull the L-shaped pin 306 in the previous limiting structure 3 upward and pull the handle 305 to insert the L-shaped pin 306 into the circular through hole near the rear end on the upper surface of the limiting plate 301. Then, repeat the above operation on the next limiting structure 3, successively removing the screen outer frame 4. When reinstalling the screen outer frame 4, in the lowest limiting structure 3, pull the handle 305, pull up the L-shaped pin 306, and then insert the L-shaped pin 306 into the circular through hole in the middle of the upper surface of the limiting plate 301. The screen outer frame 4 is placed between the J-shaped clamps 303. Then pull up the L-shaped pin 306, release the handle 305, and the J-shaped clamp 303 clamps the screen outer frame 4 due to the No. 1 spring 304. The L-shaped pin 306 is inserted into the circular through hole at the front end of the limiting plate 301. Repeat the above operation to install the screen outer frame 4 successively. The support tube 1 and the concave ring 2 cooperate with the limiting structure 3 to make it easier to disassemble and assemble the screen outer frame 4. The disassembly and assembly method is simpler and is conducive to the cleaning, maintenance and replacement of potassium chloride granule screens.

[0027] In this embodiment, the auxiliary support leg 5 includes a limiting block 501, a limiting base 502, and a second spring 503.

[0028] In this embodiment, six limiting blocks 501 are provided. The limiting blocks 501 are fixedly installed on the lower surface of the lowest concave ring 2. The limiting blocks 501 are evenly distributed on the lower surface of the concave ring 2. The two ends of the limiting blocks 501 are inserted into the through holes at the upper end of the limiting base 502. The second spring 503 is fixedly connected to the lower surface of the limiting blocks 501. The lower end of the second spring 503 is fixedly connected to the limiting base 502. The bolt passes through the through hole on the lower surface of the limiting base 502 to fix the multi-level screen fixing frame to the vibration structure of the drug granulation screening device. When the vibration structure of the drug granulation screening device vibrates, it drives the multi-level screen fixing frame to vibrate. The second spring 503 between the limiting blocks 501 and the limiting base 502 increases the vibration amplitude. The two ends of the limiting blocks 501 slide along the through holes at the upper end of the limiting base 502. The auxiliary support 5 can increase the vibration amplitude of the multi-level screen fixing frame, which is beneficial to the screening of potassium chloride particles on the screen frame 4.

[0029] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
