Description

A dust recovery device for silica gel production

technical field

The utility model relates to the technical field of silica gel production, more specifically, it relates to a dust recovery device for silica gel production.

Background technique

In the production process of silica gel, various powdery raw materials need to be stirred and mixed in the mixing tank. During the process of pouring various powdery raw materials, there will be a large amount of dust floating in the air, causing environmental pollution in the workshop. The functions of the devices used to recover dust in the prior art are relatively simple, and usually only have the function of recovering dust. Long-term use is easy to age the equipment and affect the recovery effect.

In order to solve the above problems, Chinese patent (publication number: CN210079073U) discloses a dust recovery device produced by silica gel, comprising: a dust recovery box and a water spray mechanism; the side wall of the dust recovery box is provided with an air inlet; the top of the dust recovery box The wall is provided with an air outlet; the bottom wall of the dust recovery box is provided with a powder outlet; the dust recovery box is provided with a filter plate; the water spray mechanism includes a motor, a rotating shaft, a water inlet assembly and a water outlet assembly.

Although the above technical solution cooperates with the dust recovery box and the water spray mechanism, the dust recovery device has the functions of dust recovery and internal cleaning of the device. It can regularly clean the device and regularly remove the dust attached to the inside of the device. Ensure the cleanliness of the internal environment of the device. However, the inventor found in the process of realizing the above technical solution that although the recovery device is provided with a corresponding wind deflector to assist the separation of dust and air, so that most of the dust directly sinks down to the powder outlet for collection, but in the process Under the action of the air circulation of air outlet -> air outlet, there will always be some dust with smaller particles (lighter weight) that will follow the circulating air and be blocked on the filter plate. At this time, if the vibrator is used to force the filter plate to vibrate , will make part of the dust pass through the mesh of the filter plate and overflow the air outlet with the circulating air (because when the filter plate vibrates, the dust that originally adhered to the filter mesh will be shaken down and spread on both sides of the filter plate side), polluting the workshop environment and endangering the health of workers.

Utility model content

The purpose of this utility model is to provide a dust recovery device for silica gel production, which solves the problem of dust overflow in the existing recovery device, which will pollute the workshop environment and endanger human health.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a dust recovery device for silica gel production, including a recovery box, an air inlet is opened on the top of the recovery box, and an air outlet is opened on the side wall of the recovery box, and A filter screen is installed at the air outlet; the air inlet assembly is connected to the top of the recovery box through the air inlet, and the air inlet assembly is used to suck the air mixed with dust into the interior of the recovery box; the deflector, its There are three pieces in total, and the three deflectors are staggered left and right and fixedly arranged on the inner wall of the recovery box obliquely; the settling component is arranged inside the recovery box, and the settling component is used to wet and settle the dust entering the recovery box; among them , the bottom of the recovery box is "funnel-shaped", and the bottom of the recovery box is connected with a collection assembly for collecting settled dust through a communication pipe.

The working principle of this technical solution: when in use, start the air intake assembly and the settling assembly at the same time, the air intake assembly will suck the air mixed with dust in the workshop into the interior of the recovery box, and then the air will flow through three staggered deflectors The flow velocity slows down under the action of the flow, and the dust mixed in it begins to sink.
