Description

A powder recovery device

technical field

The utility model relates to a powder recovery device, which belongs to the field of powder metallurgy equipment.

Background technique

Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw materials to manufacture various metal materials and composite materials. Due to the advantages of powder metallurgy technology, it has become a solution to the problem of new materials. The key plays a pivotal role in the development of new materials. However, in the powder metallurgy production process, from the initial powder manufacturing, mixing to product molding, and even the grinding and finishing after product molding, powder leakage and powder loss will inevitably occur. Due to powder leakage and powder loss, Not only does it cause a lot of waste of raw materials, but also the quality of these powders will be greatly reduced due to impurities such as dust. In the prior art, the recovery of metal powder in powder metallurgy usually only recovers the powder, without considering the further purification and removal of impurities in the recovery of metal powder.

Utility model content

The technical problem to be solved by the utility model is to provide a powder recovery device, which can not only recover metal powder, but also remove impurities and purify the powder during the powder recovery process.

The utility model is achieved through the following technical solutions:

A powder recovery device, comprising a collector, a recovery pipeline located below the collector, a powder recovery chamber and a blower, a mesh window is arranged on the inner wall of one side of the recovery pipeline, and the other side of the recovery pipeline is fixedly connected to an inlet An air branch pipe, the air inlet branch pipe includes an air inlet pipe and an air outlet pipe, and the blower blows air to the recovery pipe through the air inlet pipe of the air inlet branch pipe.

Further, the mesh window is a magnetic mesh window.

Further, a storage bag is connected to the outside of the mesh window.

Further, the air inlet of the air inlet branch pipe faces downward, and the angle between the air inlet branch pipe and the recovery pipe is 30-40°.

Further, the air outlet of the air inlet branch pipe is located on the same horizontal line as the lower edge of the mesh window.

Further, there is a hose connected between the air blower and the air inlet branch pipe.

Further, the blower is placed in the powder recovery chamber.

Further, at least two universal wheels are connected to the bottom of the powder recovery chamber.

The beneficial effects achieved by the utility model:

(1) A powder recovery device of the present utility model has a simple structure and is easy to operate. It can not only recover the missing metal powder, but also further dedust and purify the powder, improving the quality of recovered metal powder;

(2) The magnetic mesh window can also intercept the lost metal powder while serving as the outlet of impurities, reducing powder waste.

(3) The inlet pipe of the air inlet branch faces downward, so that the air inlet can contact the metal powder in reverse to improve the impurity removal effect. The angle between the air inlet pipe and the recovery pipe is 30-40°, which not only ensures the maximum contact between the air inlet and the metal powder It also prevents the metal powder from receiving too strong blast, which affects the falling of the powder; the air outlet of the air inlet branch pipe and the lower edge of the mesh window are located on the same horizontal line so that the metal powder receiving the blast is located on the net as much as possible. Within the range of the shape window, it is more conducive to the escape of impurities.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figure 1, a powder recovery device includes a collector 1. In this embodiment, the collector 1 is funnel-shaped, but the utility model is not limited to the funnel shape, and the recovery pipeline 2 arranged in a vertical direction and located below the collector , the powder recovery chamber 4 and the blower 9, the collector 1 is fixedly connected with the recovery pipeline 2, a mesh window 3 is opened on one side of the recovery pipeline 2, and the other side of the recovery pipeline is fixedly connected with an air inlet branch pipe 6, and the mesh window 3 is connected with the The position of the air inlet branch pipe 6 is relative, that is, it is located on the opposite sides of the recovery pipe. The air inlet branch pipe includes an air inlet pipe mouth and an air outlet pipe mouth. 2 Inner blast.

Preferably, the mesh window 3 of the device is a magnetic mesh window, and the outside of the mesh window 3 is covered with a storage bag.

Preferably, the air inlet of the air inlet branch pipe 6 faces downward, and the angle between the air inlet branch pipe 6 and the recovery pipe 2 is 30-40°, which is determined through repeated tests and adjustments, and the angle is too small It will cause excessive dispersion of the powder, which is not conducive to the effective landing of the powder. If the angle is too large, the contact area between the powder and the wind is not large enough. The lower edge is on the same horizontal line.

Preferably, a hose 7 is also connected between the blower 9 and the air inlet branch pipe 6 .

Preferably, at least two universal wheels 5 are connected below the powder recovery chamber to ensure flexibility during use.

In actual use, the metal powder enters from the collector 1 and falls into the vertical recovery pipe 2 under the action of gravity. According to the density difference between the metal powder and impurities such as dust, the metal powder is subjected to the wind from the air inlet branch pipe 6. Blowing, the impurities are separated from the metal powder, and most of the metal powder continues to fall to the powder recovery chamber 4, and the impurities are blown into the storage bag 10 through the magnetic mesh window 3, and some metal powder blown away together with the impurities will be blown away. The magnetic mesh window 3 is sucked, which is convenient for recycling.
