Description
Technical Field
[0001] This utility model relates to the field of powder raw material weighing, specifically a purification structure for weighing pharmaceutical powders. Background Technology
[0002] In the pharmaceutical production process, it is necessary to weigh the powder raw materials used. Due to the small size of the powder particles, they are easily splashed and generated as dust during the weighing, loading, unloading, or moving process. This makes the weighing workshop dirty and messy. In addition, the dust not only disperses in the weighing workshop, but also falls on the ground or weighing equipment, interfering with the subsequent weighing of pharmaceutical powders. This may result in different pharmaceutical components being mixed into the subsequent pharmaceutical powders, affecting the safety of subsequent pharmaceutical production. Utility Model Content
[0003] The purpose of this utility model is to provide a purification structure for weighing pharmaceutical powders. It can solve the technical problem that dust is easily generated during the weighing of pharmaceutical powders, which interferes with subsequent weighing. It effectively adsorbs dust and avoids powder residue on the weighing platform, reducing interference with subsequent pharmaceutical powder weighing and ensuring the safety of pharmaceutical production.
[0004] To achieve the above objectives, this utility model employs the following technical solution: A purification structure for weighing pharmaceutical powder includes a purification chamber, a weighing platform inside the purification chamber, multiple side walls of the purification chamber having dust suction holes, a dust suction head connected to the dust suction holes on the outer side of the purification chamber, symmetrical baffles on both sides of the weighing platform having perforations, symmetrical telescopic tubes connected to the dust suction holes on the side walls of the purification chamber, a dust suction plate at the end of the telescopic tube for use with the baffles having purification holes, a power component inside the purification chamber for driving the dust suction plate to move, and the purification holes and perforations being aligned when the dust suction plate contacts the baffles.
[0005] Furthermore, the suction port includes a front suction port and a side suction port, with the height of the front suction port being higher than the height of the side suction port.
[0006] Furthermore, the telescopic tube is located at the side suction hole and communicates with the side suction hole.
[0007] Furthermore, the power assembly includes a slide rail, a slide rod, a motor, and a screw. There are multiple slide rails fixed to the side wall of the cleanroom. There are multiple slide rods fixedly connected to the dust collection plate. The slide rods are slidably connected within the slide rails. The motor is fixed to one of the slide rails. The screw is fixed to the output shaft of the motor. The end of the slide rod is provided with a slider. The screw passes through the slider and is threadedly connected to it.
[0008] Furthermore, the slide bar has a groove inside, and the screw extends into the groove after passing through the slide bar.
[0009] Furthermore, the longitudinal section of the slide is an inverted U-shape, and the slide rod passes through the opening at the bottom of the inverted U-shape and connects to the dust collection plate.
[0010] Furthermore, the bottom of the dust collection plate is provided with multiple rollers, which make rolling contact with the bottom of the purification chamber.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structure of this utility model is provided with multiple dust suction holes on the side wall of the clean room, and a dust suction head connected to the dust suction holes is provided on the outside of the clean room. This structure allows the dust generated during the weighing of medicine powder to be effectively sucked away by the dust suction holes, thereby avoiding the residue of powder in the clean room, thus effectively reducing the interference with subsequent weighing of medicine powder, ensuring the cleanliness of the clean room, and ensuring the safety of medicine production. 2. Symmetrical baffles with perforations are installed on both sides of the weighing platform. Telescopic tubes connected to dust extraction holes are symmetrically installed on the side walls of the cleanroom. This structure allows the dust extraction plate to move using a power unit after weighing. During this process, the telescopic tubes maintain communication between the dust extraction plate and the dust extraction hole. When the dust extraction plate contacts the baffle, the cleanroom hole and the perforation align. This structure allows residual drug powder on the weighing platform to be sequentially drawn away through the perforations, cleanroom hole, telescopic tube, and dust extraction hole, effectively adsorbing and removing residual powder. This ensures that subsequent weighing of drug powder does not involve other drug components, resulting in a more thorough cleaning of the drug powder in the cleanroom and further guaranteeing the safety of drug production.

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0019] Reference Figure 1 and Figure 2This utility model describes a purification structure for weighing pharmaceutical powders. The main structure includes a purification room 1, where the weighing of pharmaceutical powders is completed. The purification room 1 is equipped with a weighing scale 2. The weighing scale 2 can be any existing commercially available scale structure for weighing pharmaceutical powders, with improvements made to the structure and weighing principle of the asymmetrical weighing scale 2. For specific examples, refer to the ultra-low platform scale structure, model SCS-YDH-1T, sold by Guangdong Dingheng Automation Equipment Co., Ltd. Multiple side walls of the purification room 1 are equipped with dust suction holes that penetrate the side walls. A dust suction head 3, connected to the dust suction holes, is located on the outside of the purification room 1 and communicates with an external dust collection system, thereby generating dust at the dust suction holes. Sufficient suction power facilitates the removal of spilled powder materials, preventing residue and dust generation in the cleanroom 1, reducing interference with subsequent pharmaceutical powder weighing, and ensuring the cleanliness of the weighing area and the safety of subsequent pharmaceutical production. The weighing platform 2 has symmetrically fixed baffles 4 on both sides via welding or integral molding. The baffles 4 act as barriers on both sides of the weighing platform 2, ensuring the stability of the bagged pharmaceutical powder placed on it. The baffles 4 have through-holes 5, allowing spilled powder to pass through and be sucked away by the suction port. The cleanroom 1 has symmetrically installed telescopic tubes 6 connected to the suction ports on its side walls. The telescopic tubes 6 are made of rubber or plastic. The end of the device is fixed with a suction plate 7 for use with a baffle 4 by adhesive or bolts. The suction plate 7 has through-holes 8, and the distribution of the suction holes 8 corresponds to the positions of the through holes 5. The purification chamber 1 is equipped with a power component to drive the suction plate 7 to move. When the suction plate 7 contacts the baffle 4, the suction holes 8 and the through holes 5 are aligned. Specifically, a sealing ring is set on the side of the suction plate 7 to improve the sealing at the connection when the suction plate 7 contacts the baffle 4, ensuring sufficient suction. In this structure, during weighing, the telescopic tube 6 is in a retracted state, so that the suction plate 7 is positioned close to the side wall of the purification chamber 1, which will not cause interference to the weighing process. The telescopic tube 6 connects the suction holes and the purification holes 8, so that sufficient suction is generated at the purification holes 8. The suction force allows the raw material powder that spills into the environment from above the baffle 4 or through the perforations 5 on the baffle 4 to be sucked away by the purification holes 8. After weighing, the power unit drives the dust suction plate 7 to move toward the baffle 4, extending the telescopic tube 6 while maintaining the connection between the dust suction hole and the purification hole 8. When the dust suction plate 7 contacts the baffle 4, the purification hole 8 aligns with the perforations 5, generating suction at the perforations 5 on the baffle 4. This sucks away the remaining drug powder on the weighing platform 2, making the cleaning of drug powder in the purification room 1 more thorough. This effectively avoids drug powder residue in the purification room 1 and on the weighing platform 2, reduces interference with subsequent drug powder weighing, prevents the mixing of other drug components, and further ensures the safety of subsequent drug production.
[0020] Preferably, the dust suction holes include a front dust suction hole 9 and a side dust suction hole 10. The front dust suction hole 9 is located in front of the weighing platform 2, and the side dust suction holes 10 are located on both sides of the weighing platform 2. The height of the front dust suction hole 9 is higher than the height of the side dust suction holes 10. This structure can form dust suction points with alternating heights on the periphery of the weighing platform 2, thereby making the adsorption of spilled drug powder more comprehensive and thorough, and further improving the effect of cleaning drug powder.
[0021] Preferably, the telescopic tube 6 is located at and communicates with the side suction hole 10. The side suction hole 10 is positioned low. When the weighing platform 2 is low, the low-height side suction hole 10 can fully absorb the medicine powder spilled from the weighing platform 2. It can also be aligned with the perforation 5 on the side baffle 4 of the weighing platform 2 to absorb the medicine powder remaining on the weighing platform 2. This makes the adsorption and cleaning of medicine powder more targeted and further improves the effect of adsorption and cleaning of medicine powder.
[0022] Preferred, refer to Figure 4 and Figure 5 The power assembly includes a slide rail 11, a slide rod 12, a motor 13, and a screw 14. Multiple slide rails 11 are fixed to the side wall of the cleanroom 1 by welding or bolting. Multiple slide rods 12 are fixed to the dust collection plate 7 by welding or bolting. The slide rods 12 are slidably connected within the slide rails 11. The motor 13 is fixed to one of the slide rails 11 by welding or bolting. The screw 14 is fixed to the output shaft of the motor 13 by welding or bolting. A slider 15 is fixed to the end of each slide rod 12 by welding or integral molding. The screw 14 passes through the slider 15 and is threadedly connected to it. When the motor 13 drives the screw 14 to rotate, it can drive the slider 15 and the sliding rod 12 connected to it to slide within the slide rail 11, thereby driving the dust collection plate 7 to move. This structure makes the sliding drive of the dust collection plate 7 more efficient and accurate. The sliding movement of the sliding rods 12 at multiple positions on the dust collection plate 7 relative to the slide rail 11 makes the sliding structure of the dust collection plate 7 more stable, ensuring the tight fit between the dust collection plate 7 and the baffle 4, and ensuring the adsorption effect of powder on the symmetrical weighing platform 2.
[0023] Preferably, the slide bar 12 has a groove 16 inside, and the screw 14 extends into the groove 16 after passing through the slider 15. This structure ensures that the screw 14 is always located in the groove 16 inside the slide bar 12, so that the screw 14 is not exposed to the outside, thus making it difficult for impurities such as medicine powder to adhere to the screw 14, and ensuring the smoothness of the screw 14 driving the slider 15.
[0024] Preferred, refer to Figure 3The longitudinal section of the slide 11 is an inverted U-shape. The inverted U-shape structure makes it difficult for dust and impurities to accumulate inside the slide 11. The slide rod 12 passes through the opening at the bottom of the inverted U-shape and connects to the dust collection plate 7. This structure makes it difficult for dust and impurities to accumulate inside the inverted U-shape, so that the slide rod 12 will not get stuck when it slides in the slide 11, ensuring the smoothness of the sliding movement of the dust collection plate 7.
[0025] Preferably, the bottom of the dust collection plate 7 is rotatably connected to multiple rollers 17 via bearings. The rollers 17 roll in contact with the bottom of the purification room 1. The rollers 17 can form a support between the bottom of the dust collection plate 7 and the bottom of the purification room 1, making the structure of the dust collection plate 7 more stable when it moves, thereby improving the accuracy of the subsequent alignment of the dust collection plate 7 with the baffle 4.
[0026] Working Principle: This invention features multiple dust extraction holes on the side wall of the cleanroom 1. A dust extraction head 3, connected to these holes, is located on the outside of the cleanroom 1. This structure allows the dust generated during the weighing of pharmaceutical powder to be effectively removed by the dust extraction holes, thus preventing powder residue in the cleanroom 1 and effectively reducing interference with subsequent pharmaceutical powder weighing. This ensures the cleanliness of the cleanroom 1 and guarantees the safety of pharmaceutical production. Symmetrically arranged baffles 4, each with perforations 5, are positioned on both sides of the weighing platform 2. Telescopic tubes 6, connected to the dust extraction holes, are symmetrically arranged on the side wall of the cleanroom 1. After weighing, the structure allows the power unit to drive the dust suction plate 7 to move. During this process, the telescopic tube 6 maintains the connection between the dust suction plate 7 and the dust suction hole. When the dust suction plate 7 contacts the baffle 4, the purification hole 8 and the perforation 5 are aligned. This structure allows the residual drug powder on the weighing platform 2 to be sucked away sequentially through the perforation 5, purification hole 8, telescopic tube 6, and dust suction hole, thereby effectively adsorbing and removing the residual powder on the weighing platform 2. This ensures that no other drug components are mixed in when weighing the drug powder in the subsequent process, making the cleaning of the drug powder in the purification room 1 more thorough and further ensuring the safety of drug production.
