Abstract

The utility model discloses a multi-high bagasse extractor, which comprises a frame and a hoisting apart component arranged in parallel. The component comprises a throwing roll and a screen. Every screen is composed of three parts. Bottom screen at central part is concentric arc surface having same axis core with throwing roll. Inlet and discharging region at both sides of the screen extend out. The utility model not only makes the screen extend, but also cancel the separator between two adjacent hoisting apart components. A plurality of bagasse at the feed inlet of every grade is scratched to the bottom of the screen to stir, stripping strength of fiber slag and cord slag is enhanced, at the same time, the extend of outlet benefits to the bagasse being in present hoisting screen component or the upper grade to prolong the treating time of the bagasse, at last, the aim of thoroughly separating of fiber slag and cord slag is realized. As the practice verifies, the improved technology of the utility model enhances extracting efficiency of whole machine, and has good popularizing prospect.

Description

The multi roll marrow removal machine of bagasse

Technical field

The utility model relates to the sugarcane process equipment, is specially a kind of multi roll marrow removal machine of bagasse that sugarcane fiber raw material after the sugarcane processing is removed the marrow processing.

Background technology

Bagasse behind the cane milling need be removed wherein marrow slag, stay sugarcane fiber, could be as the fibrous raw material of pulping and paper-making.Fibrous residue separates with the marrow slag, usually adopt the multi roll marrow removal machine of bagasse to realize, as shown in Figure 1 and Figure 2, the characteristics of such depithing machine are that the screen cloth 6 with elevator roller 2 and below is an elevator apart assembly, utilize the throwing of 2 pairs of bagasses of elevator roller of arranging in regular turn to raise, stirring and the filtration of screen cloth to bagasse between elevator roller scraper plate 3 and the screen cloth 6, the fibrous residue that quality is lighter is thrown to fibrous residue and is exported 5 directions, and simultaneously that the little quality of particle is heavier marrow slag filters through screen cloth.The equipment commonly used and the patent No. are 97238464.2 multi roll marrow removal machine of bagasse, the patent No. is 01212377.3 staged bagasse screening machine, the patent No. is that 02277670.2 multi roll marrow removal machine of bagasse in use still exists treating capacity and removes the unfavorable problem of marrow effect, sometimes also need remove marrow through secondary, key factor wherein is: the screen cloth 6 that is installed in elevator roller below, be typically designed to a concentric circles circular arc with the elevator roller 2 concyclic hearts, the both ends of circular arc are the feed inlet and outlet of screen cloth, and the height of feed inlet and outlet is not less than the wheel shaft of elevator roller usually, the charging aperture of the outlet next-door neighbour upper level of next stage, in the course of work, after bagasse falls from hopper 1, majority is easily thrown by elevator roller 2 and is raised out, after minority drops down onto the entrance point of screen cloth, be difficult to directly be slipped to the bottom in the cambered surface stagnation of rising steeply, fail to accept scraper plate, the dialling of rake teeth scraped and to stir, not only stop up eyelet easily, and the marrow slag is difficult to also peel off from fibrous residue, fibrous residue separates not thorough with the marrow slag.In addition, the discharging opening that screen cloth rises steeply makes bagasse upright dish out and by being raised next stage from screen cloth, and difficulty is trapped in when prime, more is difficult to turn back to upper level.Thus, the dividing plate 4 of setting is set, is beneficial to the heavier bagasse that contains the marrow slag, separate once more in prime elevator apart assembly, being detained at the screen cloth adjacent of two-stage.

The utility model content

The purpose of this utility model is to provide a kind of multi roll marrow removal machine of bagasse that bagasse is carried out repeatedly sub-sieve, fibrous residue and marrow slag are thoroughly separated that is beneficial to.

For achieving the above object, the utility model comprises frame and the elevator apart assembly that is arranged in parallel, each assembly comprises roller and screen cloth, each screen cloth is made up of three parts, the end sieve that is positioned at the middle part is and the concentric circle arc plane of the coaxial heart of elevator roller that the zone of the corresponding charging and discharging in screen cloth both sides is all departed from elevator roll shaft mind-set and expanded outward.

The utility model is not only expanded screen cloth, also cancelled simultaneously the dividing plate between adjacent two-stage elevator apart assembly, charging apertures at different levels place has more bagasse to be dialled to scrape to take to screen bottom stirs, both improved the dynamics that fibrous residue and marrow slag are peeled off, improved the cleaning dynamics of scraper plate again to screened port, prevent that eyelet from stopping up, even the expansion at discharging opening place simultaneously helps bagasse and carries out repeatedly sub-sieve current getting back in the upper level elevator apart assembly, thereby prolonged processing time, finally reached the purpose that fibrous residue and marrow slag thoroughly separate bagasse.Facts have proved that what improvement technology of the present utility model had improved complete machine removes marrow efficient, and promotion prospect is preferably arranged.

Fig. 2 is the schematic diagram of elevator apart assembly shown in Figure 1;

Fig. 3 is the structural representation of the utility model one embodiment;

Fig. 4 is the schematic diagram of elevator apart assembly shown in Figure 3.

Among the figure: 1-hopper, 2-roller, 3-scraper plate, 4-dividing plate, the outlet of 5-fibrous residue, 6-screen cloth, 6.1-feed zone, section at the bottom of the 6.2-, 6.3-discharging section.

The specific embodiment

With reference to Fig. 3, Fig. 4.The elevator apart assembly that is arranged in parallel is installed in the frame of the present utility model, and bagasse hopper 1 is arranged on the top of first order elevator apart assembly, and the rear of final stage assembly is the outlet 5 of fibrous residue.Each assembly comprises roller 2 and screen cloth 6, and the screen cloth in each assembly connects in turn.Scraper plate 4 is installed on the wheel rim of roller 2, each screen cloth is made up of three parts, the end section 6.2 at middle part is an arc surface, this arc surface and the coaxial heart of elevator roller, the feed zone 6.1 on both sides, discharging section 6.3 and roller 2 form the charging and discharging mouth of current apart assembly before and after the screen cloth, and the charging aperture of the contiguous upper level of discharging opening, the feed zone 6.1 on these both sides, discharging section 6.3 all depart from the elevator roll shaft heart, expand outwardly, form outward-dipping compass screen surface, make things convenient for the accumulation of bagasse at charging aperture, be beneficial to dialling of 4 pairs of bagasses of scraper plate on the roller and scrape and stir; Discharging opening is convenient to guide bagasse or fibrous residue, marrow slag tiltedly to throw to upper level again to go back, thereby get back to upper level or be trapped in the elevator apart assembly of prime, have only the light fibrous residue of part quality can cross roller 2 tops and fall the next stage assembly, finally separate from the fibrous residue outlet, the heavy marrow slag of quality then sieves from each screen cloth, and the two thoroughly separates.

Claims
