Description

Technical Field

[0001] This utility model relates to the field of down processing technology, specifically a dust removal device for pretreatment of down loft. Background Technology

[0002] Currently, in the down processing stage, in order to improve the loft of the down, a dust removal treatment is often performed to remove impurities and dust mixed in with the down, making it easier to process the loft after dust removal. Therefore, dust removal treatment is usually performed on the down before washing.

[0003] For example, the utility model with publication number CN219308305U discloses a dust collector for down processing, including: a main module, a filter module, and a dust removal module. The main module includes a shell, multiple legs symmetrically installed at the bottom of the shell, a base plate fixed at the end of the legs, and filter plates symmetrically installed on the inner walls of both sides of the shell. The shell has a circular cross-section and is open at both ends. In the above application, the fan blades are rotated by a motor, and air enters from one end of the shell and is sent out from the other end. Outside air with dust enters from one side of the shell. The filter plates separate larger impurities such as feathers on the outside of the shell, while dust is adsorbed by the fiber filter when passing through it, thus completing the dust removal process. However, after long-term use, the surface of the filter plates may adsorb a large amount of down, resulting in poor air permeability and reduced dust removal efficiency.

[0004] Based on this, the applicant proposes a dust removal device for pretreatment of down loft. Utility Model Content

[0005] The purpose of this invention is to address the problems of poor down dust removal effect, inability to fully disperse down, insufficient airflow to blow down, and reduced dust removal efficiency in existing down dust removal devices. The invention provides a dust removal device for pretreatment of down loft that is highly efficient, has a good dust removal effect, can fully disperse down, can fully blow down with airflow, and has high dust removal efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] A dust removal device for pretreatment of down loft includes a dust removal chamber and a discharge pipe. The dust removal chamber is mounted on a support frame. A dust discharge structure is installed at the top of the dust removal chamber, and a blower structure is installed at the bottom of the dust removal chamber. A feeding structure is installed on one side wall of the dust removal chamber, and a bearing is installed on the other side wall of the dust removal chamber. A drive motor is installed at the top of the dust removal chamber. Down that needs to be dusted is conveyed into the dust removal chamber through the feeding structure. The blower structure blows air into the dust removal chamber, causing the airflow to agitate the down and separate it from impurities, thus performing dust removal treatment on the down. The airflow carrying dust is discharged from the dust discharge structure, thereby improving the dust removal effect of the down. The drive motor is equipped with a transmission shaft, and... A drive wheel is mounted on the drive shaft. One end of the discharge pipe extends into the dust removal chamber through a bearing, while the other end is located outside the dust removal chamber. A sealing cover is movably mounted on this end. A driven wheel is mounted on the discharge pipe and is connected to the drive wheel via a belt. The drive motor drives the drive shaft and the drive wheel on the drive shaft to rotate. The drive wheel drives the driven wheel to rotate via the belt, thereby rotating the discharge pipe. The discharge pipe drives the actuating rod to rotate, which can fully agitate the down in the dust removal chamber, allowing the down to be fully separated from impurities, thus improving the dust removal efficiency and effect of the down. After the down dust removal is completed, the sealing cover can be removed from the discharge pipe to facilitate the extraction of the dust-removed down from the discharge pipe, improving the down discharge efficiency.

[0008] Preferably, the bottom of the dust removal chamber is designed with an arc shape, and a waste discharge pipe is provided at the lowest point of the dust removal chamber. A sealing cover is movably installed on the waste discharge pipe. Impurities separated from the down fall to the bottom of the dust removal chamber under the action of gravity. The arc-shaped bottom of the dust removal chamber guides the impurities into the waste discharge pipe. The sealing cover is connected to the waste discharge pipe by a thread. Opening the sealing cover allows the impurities in the waste discharge pipe to be quickly discharged from the waste discharge pipe, thereby improving the dust removal effect of the down.

[0009] Preferably, the dust removal structure includes a dust removal chamber and a dust removal fan. The dust removal chamber is located at the top of the dust removal chamber, and a dust removal pipe communicating with the dust removal chamber is installed at the top of the dust removal chamber. The bottom of the dust removal chamber is designed as an arc shape, and a dust removal hole is provided at the bottom of the dust removal chamber. The dust removal fan is installed inside the dust removal pipe. Down is conveyed into the dust removal chamber through the feeding structure. After the down is broken up, the down is separated from impurities. The dust removal fan discharges the airflow from the dust removal chamber, so that the airflow in the dust removal chamber carries dust through the dust removal hole into the dust removal chamber and is discharged from the dust removal pipe, so that the dust is quickly separated from the down, improving the dust removal efficiency and dust removal effect of the down.

[0010] Preferably, the blower structure includes a blower and an air inlet pipe. The blower is installed on the outer wall of the dust collector chamber, and an air delivery pipe is installed on the blower. The air inlet pipe enters the dust collector chamber from the bottom and connects the bottom end of the air inlet pipe to the air delivery pipe. The blower blows airflow into the air inlet pipe through the air delivery pipe. The airflow blows upward from the bottom of the dust collector chamber, which can agitate the down and facilitate the dispersal of the down, so as to quickly separate the down from impurities, thereby improving the dust removal efficiency and quality of the down.

[0011] Preferably, a fixed rod is provided at the bottom of the dust removal chamber, and an arc-shaped guide plate is provided on the fixed rod, which covers the air inlet pipe. The airflow is sprayed out from the top of the air inlet pipe. The guide plate can change the flow trajectory of the airflow, fully blow the down, and perform thorough dust removal treatment on the down, thereby improving the dust removal efficiency and effect of the down.

[0012] Preferably, the feeding structure includes a feeding cylinder and an auger. The feeding cylinder enters the dust removal chamber from the side wall of the dust removal chamber. A feeding hopper and a conveying motor are installed at one end of the feeding cylinder outside the dust removal chamber, and a discharge pipe is installed at the bottom of one end of the feeding cylinder inside the dust removal chamber. The auger is placed inside the feeding cylinder, and one end of the auger is connected to the conveying motor. The down that needs to be dusted is conveyed into the feeding cylinder through the feeding hopper. The conveying motor drives the auger to rotate, causing the auger to push the down forward in the feeding cylinder and finally discharge it from the discharge pipe. This realizes automatic feeding of down and improves the feeding efficiency of down.

[0013] Preferably, a lever is provided at one end of the discharge pipe in the dust removal chamber. The drive motor drives the transmission shaft and the drive wheel on the transmission shaft to rotate. The drive wheel drives the driven wheel to rotate through the belt, thereby driving the discharge pipe to rotate. The discharge pipe drives the lever to rotate, which can fully agitate the down in the dust removal chamber, so that the down is fully separated from the impurities, thereby improving the dust removal efficiency and effect of the down.

[0014] Beneficial effects:

[0015] 1. The drive motor drives the transmission shaft and the drive wheel on the transmission shaft to rotate. The drive wheel drives the driven wheel to rotate through the belt, which in turn drives the discharge pipe to rotate. The discharge pipe drives the actuating rod to rotate, which can fully agitate the down in the dust removal chamber, so that the down is fully separated from impurities, thereby improving the dust removal efficiency and effect of the down. After the down dust removal is completed, the sealing cover is removed from the discharge pipe to facilitate the extraction of the dust-removed down from the discharge pipe, thereby improving the discharge efficiency of the down.

[0016] 2. A fixed rod is installed at the bottom of the dust removal chamber, and an arc-shaped guide plate is installed on the fixed rod. The guide plate covers the air inlet pipe, and the airflow is sprayed out from the top of the air inlet pipe. The guide plate can change the airflow trajectory, fully blow the down, and perform thorough dust removal treatment on the down, thereby improving the dust removal efficiency and effect of the down.

[0017] 3. The down feathers that need to be dusted are conveyed from the feeding hopper into the feeding cylinder. The conveying motor drives the auger to rotate, which pushes the down feathers forward in the feeding cylinder and finally discharges them from the discharge pipe. This realizes automatic feeding of down feathers and improves the feeding efficiency of down feathers. Attached Figure Description
