Description

Device for removing hard impurities from biofuel particles

Technical Field

The invention belongs to the technical field of biofuel production equipment, and particularly discloses a device for removing hard impurities from biofuel particles.

Background

The biofuel is a novel clean fuel which takes biomass material as fuel and is mainly agricultural and forestry waste such as straw, sawdust, bagasse, rice chaff and the like. The manufacturing process is to crush, mix, squeeze, dry and the like, and the waste is made into various shapes.

At present, most of biofuel pelleting machines in China are manufactured into long cylindrical shapes, hereinafter referred to as cylindrical particles, but a large amount of biofuel powder and hard impurities exist in the manufacturing process, and all the powder and the hard impurities need to be screened out. In the prior art, most of the cylindrical particles are screened out of powder and impurities by using a screen, but the powder and impurities are inevitably required to fall from the screen by adopting vibration or shaking by using a modified method, in the process, the cylindrical particles are long and stacked together, and the cylindrical particles below the cylindrical particles can be crushed and are extremely easy to break after collision.

Disclosure of Invention

The invention aims to provide a device for removing hard impurities from biofuel particles, so as to solve the problem that cylindrical particles are easy to break during sieving.

In order to achieve the above purpose, the basic scheme of the invention is as follows: a device for getting rid of stereoplasm impurity in follow biofuel granule, including frame and funnel, the funnel is fixed to be set up in the frame, its characterized in that: a slideway is obliquely arranged on the frame, one end of the slideway is communicated with the bottom of the funnel, a sieve barrel is arranged on the frame, a feed port is arranged on the sieve barrel, a first baffle plate is detachably arranged on the feed port, and the feed port is propped against the other end of the slideway; the sieve barrel includes section of thick bamboo wall and a plurality of baffle, the baffle from the top down sets gradually on the section of thick bamboo wall, and the baffle is kept away from the one end slope of feed inlet on the sieve barrel, and the one end that is close to the slide on the baffle is equipped with first opening, first open-ended length is 2-8mm, first opening from the top down is close to the one end that keeps away from the slide in proper order, the one end that keeps away from the slide on the baffle is equipped with the second opening, and all second openings are all aligned from top to bottom, and the bottom of section of thick bamboo wall is equipped with the discharge gate, can dismantle on the discharge gate and be equipped with the second separation blade, the discharge gate communicates with the second opening that is located the below, be equipped with a plurality of sieve meshes on the baffle, the bottom of sieve barrel is equipped with the sediment box.

The working principle of the basic scheme is as follows: the cylindrical particles are poured into the funnel, enter the slideway from the funnel, slide into the feed inlet from the slideway, and finally enter the partition plate. Because the first opening is arranged on the partition board, the cylindrical particles can slide from the first opening without being accumulated on the partition board on the upper layer, and the sliding can be stopped only when the cylindrical particles slide to the partition board on the lowest layer. When the lowermost separator fills up the cylindrical particles, the penultimate separator begins to collect the cylindrical particles, so all the cylindrical particles are separated by a layer. Meanwhile, two adjacent first openings in the scheme are not aligned vertically, so that the cylindrical particles cannot fall into the first opening below immediately after sliding out of the first opening above, but fall into the first opening on the baffle plate after sliding a certain distance on the baffle plate below, and the scheme can prevent the cylindrical particles from falling to the lowest part from the uppermost part directly to cause breakage of the cylindrical particles. Finally, since the screen holes are provided in the partition plate, when the cylindrical particles slide on the partition plate, impurities and powder can fall into the slag box through the screen holes.

The beneficial effect of this basic scheme lies in: 1. cylindrical particles are placed in layers in the scheme, so that the situation that the cylindrical particles are stacked can be avoided. Simultaneously, in this scheme, utilize cylinder granule to roll on the baffle and discharge the impurity that is infected with on it in the sieve mesh, so can not produce the circumstances of cylinder granule rupture. The screen barrel can be detached to be placed on the vibrating equipment for vibrating screening, and the cylindrical particles are placed in layers in the screen barrel, so that the cylindrical particles cannot be broken. 2. In this scheme, still be equipped with the second opening on the baffle, because the cylinder granule is from the bottom up enters into every layer of baffle in proper order, so the second opening of lower floor's baffle can be plugged up by the cylinder granule, the cylinder granule on the upper baffle just can not fall from the second opening. When the cylindrical particles are required to be discharged, the cylindrical particles can gradually fall out of the second opening only by detaching the second baffle plate.

Further, a collecting box is arranged on the frame, an inlet channel is arranged on the collecting box, and the inlet channel is communicated with the discharge hole. Cylindrical particles enter the inlet channel from the discharge port and then enter the collecting tank from the inlet channel.

When cylindrical particles pass through the inlet channel and touch the wedge-shaped rod, the wedge-shaped rod moves towards the direction of the third wedge-shaped groove under the action of the cylindrical particles, and then the wedge-shaped block is driven to move towards the middle of the inlet channel, finally the wedge-shaped block is separated from the first wedge-shaped groove and moves continuously under the pushing of the cylindrical particles, and finally the wedge-shaped block is inserted into the second wedge-shaped groove, and at the moment, the cylindrical particles can fall into the collecting box through the collecting opening. In this scheme, only after cylindrical particle touches two wedge poles, the wedge can follow the roll-off in the first wedge groove, and only can touch simultaneously and touch two wedge poles when cylindrical particle keeps neat horizontally, so cylindrical particle keeps the level regular when roll-off in the collecting port, is convenient for collect and pack.

Further, a blower is arranged at the top of the screen barrel, and the blower is aligned to the partition plate. After the scheme is adopted, the air flow can clean all cylindrical particles and blow out impurities from the sieve holes after the blower is started.

Further, the distance between two adjacent separators is 6mm-12mm. The diameter of cylinder granule is generally at 6mm-8mm, adopts this scheme, can only hold a row of cylinder granule in the one deck baffle, prevents that cylinder granule from piling up together and taking place the condition of crushing.

Further, the partition plate is made of elastic materials. When the cylindrical particles fall on the partition plate, the partition plate has elasticity, so that the cylindrical particles are not easy to damage.
