Description

Technical Field

[0001] The utility model relates to the technical field of unloading devices, in particular to a dry mist dust suppression unloading device. Background Art

[0002] The unloading device refers to the device that unloads materials from the conveying machinery. Specifically, the unloader unloads the materials stored in the container or warehouse quickly and accurately through its mechanical structure. During the unloading process, the materials first flow downward under the action of gravity, and then flow along a specific path through the guidance and control of the mechanical structure.

[0003] There are many types of unloading devices, including spiral unloaders, pneumatic unloaders, electric unloaders, hydraulic unloaders, manual unloaders, plow unloaders, unloading trolleys, etc., each of which is suitable for different material characteristics and use environments. These unloading devices are widely used in the fields of construction, metallurgy, chemical industry, electric power, mining, etc., and are usually used to unload powdered, granular or block materials, such as powdered lime, cement, ore, coal, bricks, castings, gravel, etc.

[0004] Nowadays, most unloading devices usually adopt the following dust prevention methods when preventing dust:

[0005] Closed design: Many unloading devices adopt a closed structure, which completely closes the unloading area to prevent dust from leaking out. This design can effectively prevent dust from entering the environment and protect the health of operators.

[0006] Dust collection system: Some advanced unloading devices are equipped with a dust collection system, which generates negative pressure during the unloading process to suck in and collect the generated dust. This can significantly reduce the spread of dust in the air.

[0007] Spray dust suppression: Spray dust suppression technology is also one of the commonly used dust prevention methods. During the unloading process, water mist is sprayed on the material and unloading area to make the dust particles combine with the water mist and settle, thus achieving the effect of dust suppression.

[0008] Airflow control: Dust can be reduced by properly designing the airflow path of the discharge device and controlling the direction of the airflow, for example, by using airflow barriers or air deflectors to direct the dust to the collection area.

[0009] Material humidification: For some materials, proper humidification before unloading can increase the humidity of the material and reduce the generation of dust. This is usually achieved through a spray or water mist system.

[0010] Among them, for the use of spray dust suppression, although the spray dust suppression method currently used for unloading can produce water mist, its droplet size is usually large and the dust suppression efficiency is relatively low. Moreover, due to the large droplets and high humidity, this method will cause changes or losses in material properties, resulting in excessive wetting of the material.

[0011] Therefore, it is necessary to design a dry mist dust suppression unloading device to solve the above-mentioned problems. Utility Model Content

[0012] The utility model aims to provide a dry mist dust suppression unloading device to solve the problems raised in the above background technology.

[0013] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0014] A dry mist dust suppression unloading device comprises a unloading rack, a unloading plate is arranged on one side of the unloading rack, a top cover is fixedly installed on the upper outer side of the unloading rack, a dry mist dust prevention structure is arranged above and extending to the interior of the top cover, a support rod is arranged at the bottom of the unloading rack, a bearing seat is fixedly connected to the bottom of the support rod, and a dry mist generator and an air compressor are respectively arranged in the cavity between the plurality of the support rods.

[0015] As a preferred solution of the utility model, the dry mist dust-proof structure includes a transverse rod body fixedly mounted on the top of the top cover body, a water vapor distributor is arranged inside the transverse rod body, and a nozzle located at the bottom end of the top of the top cover body is connected to the water vapor distributor through a distribution pipe.

[0016] As a preferred solution of the utility model, main pipelines are arranged on the left and right sides of the transverse rod body, the other side of the main pipeline is connected to the output end of the air compressor, and the input end of the air compressor is connected to the output end of the dry fog generator.

[0017] As a preferred solution of the utility model, the water vapor distributor is also connected to a plurality of filters, and the filters are DPA paint mist filters.

[0018] As a preferred solution of the utility model, a shock absorbing device is arranged between the bottom of the unloading rack and the top of the supporting rod, and the shock absorbing device adopts a damping spring shock absorber.

[0019] As a preferred solution of the utility model, a bearing plate is fixedly connected to the top of the shock absorbing device, and the bearing plate is fixedly connected to the top of the discharge rack by means of mounting bolts.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] In the utility model, by setting up a dry mist dust suppression unloading device, when using the dry mist dust suppression to prevent dust from being applied to the unloading device, the following effects can be achieved: 1. The dry mist dust suppression technology generates ultrasonic waves by impacting the resonance cavity in the nozzle with high-pressure airflow, and fully atomizes the liquid water into droplets with a particle size of 1 to 10 microns. Such fine droplets can better combine with the dust particles in the air, thereby more effectively reducing the dust concentration generated by the dust suppression device. In comparison, although spray dust suppression can also produce water mist, its droplet size is usually larger and the dust suppression efficiency is relatively low; 2. In the process of generating water mist, dry mist dust suppression can more accurately control the amount of water used to ensure that every drop of water can play the maximum dust suppression role. This means that under the condition of achieving the same dust suppression effect, the amount of water required for dry mist dust suppression is much lower than that for spray dust suppression, thereby achieving a water-saving effect; 3. Dry mist dust suppression technology can accurately control the amount and distribution of water mist to avoid excessive wetting of materials. This is especially important for some materials that are sensitive to humidity, as it can avoid changes in the properties or losses of discharged materials due to excessive humidity. Spray dust suppression often leads to excessive wetting of discharged materials due to large droplets. 4. Dry fog dust suppression technology will not cause secondary pollution. The agglomerates formed by the combination of water mist and dust produced by discharge can naturally settle or be collected and processed, and will not cause additional burden on the environment. At the same time, due to the small amount of water used, the consumption and pollution of water resources are also reduced. 5. Due to the setting of a filter, impurities in the mist can be filtered, further improving the purity of the dry mist used for dust suppression. 6. Due to the setting of a shock absorbing device, the overall stability of the device can be improved and the noise during operation can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS
