Problems solved by technology

At present, the commonly used feed grinders are all open type grinders, which will generate a lot of dust during the grinding process, which will seriously affect the factory environment. In addition, a large amount of straw powder will be discharged along with the dust during the straw grinding process. resulting in a large waste of raw materials

Embodiment 1

[0031] see Figure 1-2 , a closed self-circulation environment-friendly straw crushing system, which includes a pulverizer 1 for material crushing, the discharge box 2 of the pulverizer 1 is connected to the inlet of the first dust removal device 10 through the first discharge pipe 4, The discharge port of the first dedusting device 10 communicates with the top of the storage tower 7, the top of the storage tower 7 is fixedly equipped with a bag filter 11, and the top of the bag filter 11 is equipped with a dust collection cover 12. The top of the dust collection hood 12 is connected to the feed port of the second dust removal device 14 through the first dust discharge pipe 13, and the discharge port of the second dust removal device 14 is connected to the top of the recovery tower 15, the The bottom of the recovery tower 15 is connected to a circulation return pipe 19 through a straight pipe 18 , and the other end of the circulation return pipe 19 is connected to the crushing...

Embodiment 2

[0043] The operating method of any one of the closed self-circulating environment-friendly straw crushing systems includes the following steps:

[0044] Step 1: Feed the straw material to be pulverized into the inside of the pulverizer 1 through the feed hopper 21, and pulverize it through the pulverizer 1;

[0045] Step2: The pulverized powder will be vertically transported to the inside of the first dust removal device 10 through the first discharge pipe 4 under the action of the internal air pressure of the pulverizer 1;

[0046] Step3: After preliminary dedusting of the powder by the first dedusting device 10, the material will automatically fall into the interior of the storage tower 7, and the generated dust will enter the first ash discharge pipe 13 through the dust collection cover 12;

[0047] Step4: The dust and material mixed powder inside the first dust pipe 13 will enter the second dust removal device 14, and the second dust removal device 14 will carry out the se...

Abstract

The invention provides a closed self-circulation type environment-friendly straw crushing system and an operation method. A discharge box body of a crushing machine is connected with an inlet of a first dust removal device through a first discharge pipe, a material falling hole of the first dust removal device is in communication with the top of a material storage tower, the top of the storage tower is fixedly provided with a bag-type dust remover, an ash collecting cover is arranged at the top of the bag-type dust remover, the top of the ash collecting cover is connected with a feeding hole of a second dust removal device through a first ash discharging pipe, a discharge port of the second dust removal device is connected with the top of a recovery tower, the bottom of the recovery toweris connected with a circulating return pipe through a straight pipe, and the other end of the circulating return pipe is connected with a crushing cavity of the crushing machine. According to the crushing system, the straw is effectively crushed in a circulating crushing mode, and meanwhile, the straw is subjected to dust removal through a dust removal system, the materials mingled in the dust removal process are sent to the crushing machine again, so that the purpose of recycling the materials is achieved.

Description

technical field [0001] The invention relates to the field of feed processing supporting equipment, in particular to a closed self-circulating environment-friendly straw crushing system and an operation method. Background technique [0002] In the feed production process, the first process needs to crush the straw, and then carry out the mixing and granulation process after crushing. At present, the commonly used feed grinders are all open type grinders, which will generate a lot of dust during the crushing process, which will seriously affect the factory environment. In addition, a large amount of straw powder will be discharged along with the dust during the straw crushing process. And then produce a large amount of waste of raw materials. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a closed self-circulating environment-friendly straw crushing system and an operation method. The crushing system effecti...
