Description

Technical Field

[0001] The utility model relates to the technical field of aluminum phosphide tablet production devices, and specifically relates to an aluminum phosphide tablet sieving powder recovery device. Background Art

[0002] At present, aluminum phosphide tablet powder screening is a technical process that involves screening aluminum phosphide tablet powder through screening equipment to remove impurities or unqualified particles therein to ensure the quality and purity of the product. This process is usually used in the chemical or pharmaceutical industry for product quality control and purification.

[0003] In the prior art, the utility model with the authorization announcement number CN217748028U is named: a powder recovery device for screening aluminum phosphide tablets. The patent includes a corrugated bar and a limit pressure plate. The interior of the recovery barrel is also equipped with a filter assembly, which is specially used for screening aluminum phosphide tablets. Below the filter assembly, there is also a cleaning assembly for scraping off the powder adhering to the bottom of the filter screen. Through the synergistic effect of the annular cover and the corrugated bar, the aluminum phosphide tablets are thrown up and down in the filter screen. This throwing makes the aluminum phosphide tablets roll in the annular cover, which helps to peel off the powder adhering to the surface of the tablets. At the same time, the vibration of the filter screen helps the powder to fall quickly. In addition, the use of the scraper and the limit bar can more effectively remove the powder on the bottom of the filter screen to ensure that the powder passes smoothly.

[0004] However, when screening powder, this patent only relies on the vibration generated when the aluminum phosphide tablets fall to complete powder separation and powder falling. The aluminum phosphide tablets are light in weight and the vibration generated is very limited, so the powder cannot be completely screened off, and the powder screening effect is not good. In addition, this patent cannot always remain horizontal. This patent vibrates when in use, and there are safety hazards if the whole is tilted.

[0005] In the prior art, the utility model with the authorization announcement number CN211358041U is named as a powder recovery mechanism for screening aluminum phosphide tablets. The patent has a recovery box with a brake wheel fixedly installed at the four corners of the bottom, an air intake mechanism is arranged on one side of the recovery box, and a mounting groove is arranged on the top side thereof, a mounting box is sealed and fixedly installed in the mounting groove, a cam connecting rod mechanism is arranged on the top inner wall of the mounting box, the cam connecting rod mechanism is fixedly connected to the mounting plate, and filter bags are fixedly arranged at equal distances on the bottom outer wall of the mounting plate, in addition, springs are fixedly installed at the four corners of the opposite side of the mounting plate and the recovery box, and limiting rods are fixedly installed on both sides of the recovery box close to the mounting plate, and limiting slide grooves matching with the two ends of the mounting plate are opened on the opposite sides of the limiting rods, the patent can effectively intercept, filter, collect and process the recovered powder to prevent the powder from further overflowing, which is mainly due to the setting of the filter bag and the air filter plug-in plate, which work together to effectively intercept and collect the powder, thereby preventing the powder from overflowing;

[0006] However, this patent still cannot ensure whether the powder is screened out completely when screening the powder, and the powder screening effect is limited, which reduces the efficiency of powder screening. Utility Model Content

After the motor 5 is started, the motor 5 drives the cam 14 to rotate, and the cam 14 continuously hits the screening plate 26. The screening plate 26 vibrates under the action of the spring 16, so that the powder on the surface of the aluminum phosphide tablets on the screening plate 26 falls off, and the conveyor belt 12 rotates at the same time, and the aluminum phosphide tablets are vibrated and screened again, so that the powder screening is more thorough.

[0031] like Figure 3 As shown, a conveyor belt 12 is commonly sleeved on the outer circumference of the two rotating rollers 10, a transverse groove is opened inside the shell 2, and the transverse rod 9 is rotatably installed inside the transverse groove.

[0032] like Figure 3 As shown, a circular groove is provided inside the collecting box 1, and a round rod 11 is rotatably installed inside the circular groove. A belt 8 is sleeved on the outer circumference of the driving wheel 6 and the driven wheel 7.

[0039] like Figure 3 to Figure 5 As shown, a thread groove is provided inside the vertical block 18, and the lifting screw 20 is threadedly connected inside the thread groove. The lifting screw 20 and the thread groove have the same shape and size.

[0040] In this embodiment, the collection box 1 is placed according to the flatness of the ground, and the distance between the anti-sliding block 19 and the collection box 1 is adjusted by rotating four lifting screws 20. When the collection box 1 reaches a horizontal state, the lifting screws 20 are stopped to ensure that the equipment remains stable during use. This adjustment step can effectively improve the stability and use efficiency of the equipment. The sieved powder falls into the collection drawer 21, and the amount of powder inside the collection drawer 21 can be observed in real time through the observation window 22, and the powder inside the collection drawer 21 can be collected and processed in time.
