Abstract

The utility model discloses a dust removal system for a rice processing plant. The utility model transports the dust in the room to the settling room through the fan above the empty rice shell room, and first removes the dust in the bag dust removal room, and the removed dust enters the dust discharge pipe due to the rotation of the filter barrel and its own gravity, and passes through The dust exhaust pipe enters the sewage outlet, and the air treated by the bag dust removal room enters the atomization dust removal room for the second dust removal. The clean air is discharged from the exhaust outlet, and the treated dust is discharged through the sewage outlet. After the air is dedusted by the dust removal system, the empty rice shells in the empty rice shell room will no longer contain dust, and the air will not be polluted when these empty rice shells are processed again.

Description

A dust removal system for a rice processing plant

technical field

The utility model relates to the technical field of rice processing, in particular to a dust removal system for rice processing plants.

Background technique

The rice processing system used in general rice processing enterprises includes: grain cleaning machine, rice huller, specific gravity separator, rice milling unit, rice sorting machine, rice polishing machine, rice selection and other equipment. When processing rice, grain cleaning machines, rice hullers, and rice milling units are mainly responsible for producing a large amount of dust. Therefore, rice processing plants connect these devices with dust suction pipes and transport the waste and dust generated to the rice shell room. , so there is a lot of dust in the air in the empty rice shell room, so there is a lot of dust mixed in the empty rice shells in the empty shell room. When these empty rice shells are processed, the air will be filled with a lot of dust, which seriously pollutes the environment. It also affects the health of the staff who handle these empty shells.

Contents of the invention

In order to solve the above problems, the utility model provides a dust removal system for rice processing plants.

The dust removal system for rice processing plants includes a paddy empty shell room, and is characterized in that: the dust removal system for rice processing plants also includes a support frame and a settling room installed on it, and the paddy empty shell room passes through and the first fan The connected first air pipe is connected to one side of the settlement room. The lower part of the settlement room is in the shape of a trumpet with a large upper part and a smaller one at the lower part. There is a sewage outlet at the bottom. The settlement room is divided into left and right rooms by a partition and connected with the empty rice shell room. The side connected to the first air duct is the left room, the left room is the bag dust removal room, and the right room is the atomization dust removal room. An electric sprayer is installed on the top of the atomization dust removal room to fill the atomization dust removal room with water mist. , one side of the atomization dedusting chamber communicates with the bag-type dedusting chamber through the second air duct passing through the partition, and the other side is provided with an air outlet, and a second fan is installed at the air outlet; the upper part of the bag-type dedusting chamber Also be provided with a crossbeam, the dustproof cover is fixed on the crossbeam, and one side of the dustproof cover is provided with an air inlet, and the air inlet is connected with the first air pipe, and the other side of the dustproof cover is provided with an air outlet, and the air outlet is connected with the second air duct. The air pipes are connected, and there is a filter barrel in the dust cover. The filter barrel is cylindrical. There are multiple bag filters evenly arranged in the filter barrel, and there is a rotating shaft in the center. There is a bearing in the middle of the top of the dust cover. The rotating shaft passes through a bearing and is connected with a motor, so that the motor drives the rotating shaft to rotate. The bottom of the dust cover is in the shape of a trumpet with a large upper part and a smaller lower part, and is connected with one end of a dust discharge pipe, and the other end of the dust discharge pipe Connected with the sewage outlet.

The settling room also includes a sewage treatment pool, and the sewage treatment pool is connected with the sewage outlet through a sewage pipe.

The motor is provided with a protective cover.

Because the chaff in the rice husk room will settle down earlier than the dust, a large amount of dust floats on the chaff. The utility model transports the dust in the room to the settling room through the fan above the empty rice shell room, and first removes dust in the bag dust removal room, and the removed dust enters the dust discharge pipe due to the rotation of the filter barrel and its own gravity, and passes through The dust discharge pipe enters the sewage outlet, and the air treated by the bag dust removal chamber enters the atomization dust removal chamber for the second dust removal. The clean air is discharged from the exhaust outlet, and the treated dust is discharged through the sewage discharge outlet. After the air is dedusted by the dust removal system, the empty rice shells in the empty rice shell room will no longer contain dust, and the air will not be polluted when these empty rice shells are processed again.

The utility model has the advantages that: the air in the empty paddy shell is processed by dust removal twice, the air is processed very clean, and will not cause physical damage to the workers who handle the empty paddy shell; It is discharged from the mouth without manual treatment.
