A multi-stage screening device for filtering organic fertilizer particles

Abstract

The utility model discloses a multi-stage screening device for filtering organic fertilizer particles, comprising a screening box. The utility model draws out the air inside the screening box by turning on a fan, and the particle screen screens the particles into the screening box. The dust enters the collecting box through a connecting pipe, and the filter plate filters the dust. The airflow drives the impeller to rotate, and the impeller drives the filter plate to rotate through a rotating rod, so as to prevent the dust from being blocked at the lower end of the filter plate. After the fan stops, the dust falls into a collecting block, and water is injected into the collecting box through a water injection hole to dissolve the dust in the water and fall into the collecting block, so as to prevent the dust from flying around when the collecting block is taken out. The motor drives the rotating shaft to rotate, and the rotating shaft drives the lower semicircular rod to rotate. During the rotation process, the lower semicircular rod collides with the upper semicircular rod, and the upper semicircular rod drives the moving rod to move up and down. The moving rod collides with the grading screen, so as to prevent the grading screen from being blocked and the problem of easy wear of the scraper.

Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage screening devices, in particular to a multi-stage screening device for filtering organic fertilizer particles. Background Art

[0002] Multi-stage screening device for organic fertilizer particle filtration is a common equipment used to remove impurities and large particles from organic fertilizer. It usually consists of multiple screens, each with different aperture sizes, which are used to separate particles of different sizes. The working principle of the multi-stage screening device is to classify organic fertilizer particles into different size grades through forces such as gravity, mechanical vibration or airflow. Larger particles will be intercepted by the screen, while smaller particles will pass through the screen to the next level of screening process. This device can usually be customized according to needs to meet different specifications and processing capacity requirements. It can be applied to various links of the organic fertilizer production line to improve the quality and purity of the product.

[0003] A particle screening and filtering device (Announcement No.: CN219850576U) is provided in the prior art, and the device is intended to solve the problem that the screening and filtering effect of the existing bio-organic fertilizer particle screening and filtering device is not ideal enough, it is not easy to perform multi-stage screening on the bio-organic fertilizer particles, and during screening and filtering, the bio-organic fertilizer particles are easily stuck on the screening hole, which is inconvenient to clean up. Through the arrangement of a receiving frame, a screening hole, a motor, a rotating shaft, a rotating frame, a scraper and a reset structure, the screening hole on the receiving frame can screen the bio-organic fertilizer particles, and the aperture of the screening hole is reduced from top to bottom, and multi-stage screening can be achieved, and the screening and filtering effect is better. During screening, the motor can drive the rotating shaft to rotate, and then the rotating frame drives the scraper to rotate, so that the bio-organic fertilizer particles stuck on the screening hole are scraped off, and the bio-organic fertilizer particles can be promoted to move, and the screening rate is improved. The reset structure can also raise and reset the scraper to prevent the scraper from being damaged.
