Description

Powder silo with function of removing accumulated powder

This creation is a powder silo with a function of removing accumulated powder, especially a powder silo used to remove the accumulated powder in the powder silo.

In the food production process, powdery raw materials such as flour are first stored in a powder silo for use in food production on an industrial production line, where the powder silo includes a silo body with a storage space. The top end of the silo body is provided with a feeding end. When raw materials are input into the powder silo, the raw materials will enter the storage space of the silo body from the feeding end of the powder silo.

However, when the raw materials enter the storage space from the feeding end of the powder silo, part of the raw materials suspended in the storage space will adhere to the inner surface of the powder silo. When the next batch of raw materials is input into the When the storage space of the powder silo is in the same place, it is easy to have cross-contamination of raw materials of different batches, which leads to food safety problems. Therefore, the raw materials accumulated on the inner surface of the silo body must be cleaned regularly.

Today's powder silo cleaning operation is to allow operators to enter the powder silo body to clean up the raw materials accumulated on the inner surface of the powder silo. However, because the air in the silo is not circulated, it is prone to hypoxia, so it is being carried out. Before the powder silo is cleaned, the powder silo must be deactivated and the storage space of the powder silo must be emptied. The workers must install the safety devices required for the cleaning operation before entering the silo to clean the raw materials left in the inner wall area. After the cleaning operation is completed, the operator must remove the aforementioned safety device before re-activating the powder silo.

The aforementioned method of manually cleaning the powder silo not only requires the powder silo to be deactivated for more than three days during the cleaning process, the cost requirements are high and the risk is high, although the originals remaining on the inner surface of the silo can be temporarily cleaned. However, at the same time when the raw materials are input into the powder silo, the problem that the raw materials adhere to the inner wall surface of the silo will be generated, so the problem of powder pollution cannot be solved.

The main purpose of this creation is to provide a powder silo with the function of removing powder deposits, in order to improve the current cleaning method of the powder silos, which is not only costly but also cannot effectively solve the problem of dust accumulation.

In order to achieve the purpose of previous disclosure, the powder silo with the function of removing powder deposits in this creation includes: a silo body, the top of which forms a feeding end, and a silo storage space is formed inside the silo body; and a nozzle group, which is arranged Inside the silo and located at the upper section of the storage space, the nozzle group includes a ring-shaped upper section nozzle, a ring-shaped lower section nozzle, and an air inlet pipe, and the upper section nozzle and the lower section nozzle are spaced up and down from each other. The upper nozzle is formed with a plurality of upper nozzles which are spaced toward the inner wall of the chamber and spaced apart, and the lower nozzle is formed with most of the lower nozzles which are spaced toward the inner wall of the chamber and the intake pipe communicates with the upper nozzle and the The lower nozzle is extended out of the chamber from the chamber.

The powder silo with the function of removing accumulated powder in this creation is used to store powdery raw materials such as flour. The inlet pipe of the nozzle group is used to connect an air supply device and has the following advantages:

1. Can effectively remove the powder deposits on the inner surface of the silo: The powder silos with the function of removing powder deposits can inject dry gas into the nozzle group through an external air supply device, and the injected gas will be from the upper nozzle. The upper nozzle and the lower nozzle of the lower nozzle spray out and blow off the raw materials attached to the inner wall surface of the chamber with the ejected gas, which can effectively remove the problem of powder accumulation on the inner wall of the chamber, and thus avoid cross-contamination of the raw materials in different batches.

2. Reduce operation cost: As mentioned above, the powder silo with dust removal function in this creation only needs to be connected to an external air supply device, and the gas supply device can provide gas to carry out the dust removal operation. The dust accumulation inside the warehouse must be cleaned manually, which can effectively reduce the operation cost.

3. Does not affect the production line: The powder silo with the function of removing powder deposits in this creation is supplied by external air supply device, and the raw materials attached to the inner wall surface of the silo are blown off with gas, and the accumulated powder in the silo is regularly cleaned. There is no need to deactivate the powder silo, which can continue the production line, so it will not affect the production process of the production line.

4. High security: The powder silo with the function of removing powder deposits in this creation is the airflow method to blow off the raw materials attached to the inner surface of the silo, and the air supply device for air supply is installed outside the silo. During the process of dust removal, no sparks will be generated inside the bin, which can prevent dust explosion and improve the safety of the operation.
