Advantages of Hand lifting type vacuum feeder

The core features of the hand-cranked vacuum feeder are reflected in its unique human-machine collaborative design and flexible application performance.

Manpower drive and flexible lifting: The vacuum generating mechanism is driven by the hand-cranked device, and the height of the silo can be manually adjusted. It is suitable for different equipment stations and is equipped with a mobile base for easy movement in the workshop.

Compact and practical structure: The core consists of a piston/diaphragm vacuum mechanism, a stainless steel silo, a high-efficiency filter and a discharge valve, which occupies a small area and is easy to maintain.

Closed conveying: Materials are transported in a closed pipeline, equipped with a high-precision filter to prevent dust from spilling, meeting the hygiene requirements of the food, medicine and other industries.

Economical and low-consumption: No need for electric drive, extremely low energy consumption, purchase and maintenance costs are much lower than automated equipment, suitable for small and medium-sized batch production.

Wide material adaptability: It can transport powdered and granular materials, and can also reduce the loss of high-value or easily oxidizable materials through a vacuum environment.

Hand lifting type vacuum feeder composition structure

It uses a three-section stainless steel lifting column and a labor-saving gear set, with a vacuum suction system and a quick-release flange to achieve closed powder conveying without electric drive.

Vacuum generating mechanism​: There are two common types: piston type and diaphragm type. The piston type realizes the change of chamber volume through the reciprocating motion of the piston in the cylinder to generate a vacuum; the diaphragm type uses the elastic deformation of the diaphragm to achieve the same effect.

Lifting system​: The hand-cranked device drives the screw or chain to achieve the up and down movement of the silo. This design enables the equipment to flexibly adapt to receiving equipment of different heights. Whether it is a low mixing tank or a tall reactor, it can be accurately docked to complete material addition.

Silo and filter device: Generally made of stainless steel, it has good corrosion resistance and sturdiness and can adapt to various material characteristics.

Mobile base: To facilitate the movement of equipment in the workshop, the hand-cranked lifting type vacuum feeder is usually installed on a mobile base with rollers. The rollers generally have good wear resistance and steering flexibility, and some also have brake functions to fix the equipment after reaching the working position.

Working principle of hand lifting type vacuum feeder

The working principle of the hand-cranked lifting type vacuum feeder revolves around human drive and vacuum negative pressure. The operator shakes the rocker to drive the piston or diaphragm mechanism in the equipment to reciprocate, so that the volume of the sealed chamber changes periodically, and negative pressure is formed when the volume increases. This vacuum state is transmitted through the suction pipe and suction nozzle. Under the action of atmospheric pressure, powdered or small particles are sucked in and sent to the silo. After the material and air mixture flows into the silo, the material falls due to gravity, and the air is purified and discharged through the top filter. After the suction is completed, the discharge valve at the bottom of the silo is manually opened, and the material falls into the target container by gravity. After closing the valve, the next suction cycle can be started.

What is the lifting height of the hand-cranked vacuum loader?

The lifting height of the hand-cranked vacuum loader usually varies according to the model and design. The following is a detailed parameter description.

The standard lifting height of the hand-cranked vacuum loader is 1.2-3 meters: it can meet the needs of most production scenarios, such as lifting the floor material barrel to the 1.5-meter high mixer feed port, or conveying the pallet material to the 2.2-meter high packaging machine, and a single lifting takes only 15-30 seconds.

The maximum lifting height of the extended model can reach 5 meters: but it needs to be equipped with a reinforced chain drive system and follow safety restrictions. When it exceeds 3 meters, the load must be ≤20kg, and a fixed bracket must be installed to prevent shaking. Special customized models can be adapted to 4-5 meters high operations.

Targeted recommendations for different scenarios: Laboratory operations prefer 1.2-1.8 meters in height to match the biosafety cabinet; standard production lines are suitable for docking reactors in the range of 2-3 meters; special high-level operations require customized 4-5 meters solutions. All models are equipped with safety card slots for positioning, and it is recommended to use them strictly according to the load-bearing curve (≤30kg within 3 meters, ≤20kg for 3-5 meters).

In what scenarios are hand-cranked vacuum loaders generally used?
