A straw briquetting device for adjusting the molding size

Abstract

The invention discloses a straw compression device capable of adjusting moulding size. The straw compression device comprises a support; a heating pipe is fixedly connected to the upper side of the support; a first round barrel is arranged in the heating pipe and is coaxially arranged with the heating pipe; a second round barrel is rotatably connected to the inner side of the first round barrel; arotary shaft is rotatably connected into the second round barrel and is coaxially arranged with the second round barrel; a packing auger is arranged on the outer side of the rotary shaft in a sleeving manner; a barrel cover which is matched with the heating pipe is arranged above the heating pipe; a motor is arranged on the upper side of the barrel cover; the output shaft of the motor penetratesthrough the center of the barrel cover and is fixedly connected with the rotary shaft; a material inlet bin is arranged on one side of the barrel cover; a material outlet bin is arranged on the lowerside of the support; a dedusting device is connected to one side of the material outlet bin; and a filter net is arranged at the connection part of the material outlet bin and the dedusting device. The straw compression device has the advantages that the double barrel-shaped round barrels are adopted, and a handle is arranged on an outer round barrel, so that moulding size can be adjusted; besides, a heating device is arranged, so that materials can be better moulded; and meanwhile, the dedusting device is arranged at a material outlet, so that dust is reduced when the materials are discharged.

Description

technical field [0001] The invention relates to the technical field of straw briquetting, in particular to a straw briquetting device for adjusting the forming size. Background technique [0002] Straw briquette fuel is a modern clean fuel that uses new technology and special equipment to compress and carbonize various crop straw, wood chips, sawdust, peanut shells, corncobs, straw, wheat straw, branches and leaves, licorice, etc., without any additives and binder. It can solve the basic living energy in rural areas and improve farmers' income, and it is also an emerging special fuel for biomass power generation. [0003] Today's straw briquettes are usually squeezed by a screw device to pressurize the material from the formwork, but most of the molding machines can only form one size of briquette fuel. For different sizes of fuel, it is necessary to change the formwork. For production has caused inconvenience, has also reduced production efficiency. Contents of the inve...
