Rotating cylinder for fertilizer drier
Technical field
The present invention relates to whizzer field, particularly relate to a kind of rotating cylinder for fertilizer drier.
Background technology
Currently, during using drum granulating method to produce compound fertilizer, water vapour to be passed through is to increase the humidity of raw material, the balling-up so that fertilizer can preferably bond.But, moisture too much in compound fertilizer product can affect the quality of product, and therefore, in order to reduce in product, moisture is to acceptability limit, and compound fertilizer is dried by general employing whizzer.In drying course, higher owing to having just enter into the compound fertilizer moisture in whizzer, easily stammer on the barrel of whizzer, had a strong impact on production efficiency and the quality of compound fertilizer product.Simultaneously as the heat waste that combustion furnace carries to whizzer is relatively big, and the coal that thus caused and the waste of electric power resource.
In order to solve above-mentioned technical problem, prior art proposes following technology:
As China Patent No. " 201320120239.3 " discloses a kind of whizzer, its publication date is on October 16th, 2013, its technical scheme is described whizzer, including rotating cylinder, being provided with multiple automatic knocking device on described rotating cylinder, described automatic knocking device includes striking mechanism, position-limit mechanism and reinforcing mechanisms;Wherein, described striking mechanism is hinged on the outer wall of described rotating cylinder by rotating shaft, and the axis of described rotating shaft is parallel with the axis of described rotating cylinder;Described position-limit mechanism is fixed on the outer wall of described rotating cylinder, and the contrary side of the direction of rotation that is positioned at described rotating cylinder is for limiting the rotation direction of described striking mechanism;Described reinforcing mechanisms is fixed on the outer wall of rotating cylinder, and the side that the direction of rotation that is positioned at described rotating cylinder is identical, and described striking mechanism beating point on rotating cylinder is positioned on described reinforcing mechanisms.This patent mainly shakes on scattered rotating cylinder inwall the fertilizer of stammerer by knocking device, but in actual use, if the percussion power of knocking device is spent gently, do not reach again shake and dissipate the effect of fertilizer, if and the percussion power of knocking device is spent greatly, the most easily damage rotating cylinder, cause rotating cylinder to deform.Additionally, stammer on rotating cylinder inwall due to fertilizer, use knocking device to be shaken off from rotating cylinder inwall by the fertilizer of stammerer, but owing to the moisture in stammerer fertilizer is more, cause knocking device to be difficult to shake eliminating stagnation bar fertilizer, still can affect production efficiency and the quality of fertilizer.
Summary of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, a kind of rotating cylinder for fertilizer drier is provided, the present invention can strike off the fertilizer of stammerer on rotating cylinder inwall, and breaks up stammerer fertilizer while striking off, and reaches to improve fertilizer production efficiency and the purpose of quality.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of rotating cylinder for fertilizer drier, it is characterized in that: include cylinder, left rotary shaft, right spindle, support column and scraper plate, described left rotary shaft and right spindle are separately fixed at the two ends of cylinder, described right spindle is hollow axle, one end of described support column is movably set in hollow right spindle by bearing, the other end stretches in cylinder, and be connected with left rotary shaft bearing, described scraper plate is arranged on the top in cylinder, its two ends are fixing on the support columns by connecting rod respectively, and described scraper plate is provided with multiple scraping teeth for striking off stammerer fertilizer.
Described scraper plate is the arc suitable with cylinder inboard wall.
Multiple scraping teeth on described scraper plate are multirow distribution, and adjacent rows scraping teeth is dislocatedly distributed.
Multiple aperture pore more than fertiliser granulates external diameter it is provided with on described scraper plate.
The bottom of described scraper plate is provided with 37 electric heating tubes.
Described support column is internally provided with wiring channel, and the power line of described electric heating tube is connected up by wiring channel.
Employing it is an advantage of the current invention that:
One, in the present invention, one end of support column is flexibly connected with left rotary shaft, and the other end is movably set in hollow right spindle by bearing, and support column can either be positioned by this structure, prevents scraper plate thereon from rotating, does not interferes with again the smooth rotation of whole rotating cylinder.Scraper plate and scraping teeth are arranged on the structure of cylinder internal upper part, have the advantage that can quickly strike off and break up stammerer fertilizer.This is because when the top that fertilizer of stammering moves in cylinder, cylinder is minimum to the power of influence of stammerer fertilizer, adds the reason of stammerer fertilizer self gravitation so that stammerer fertilizer is easiest to during the top be stripped off in cylinder.Compared with the prior art that China Patent No. " 201320120239.3 " is representative, the present invention processes stammerer fertilizer from inner barrel, stammerer fertilizer can be broken up while striking off by scraping teeth, both tube structure had not been interfered with, there is again preferable treatment effect, it is possible to be effectively improved production efficiency and the quality of fertilizer.
Two, in the present invention, scraper plate is set to the structure of the arc suitable with cylinder inboard wall so that the more regularization of the scraping teeth on scraper plate, i.e. can determine the height of high scraping teeth so that scraper plate and scraping teeth can mold manufacture, advantageously reduce the production cost of scraper plate.
Three, in the present invention, the multiple scraping teeth on described scraper plate are multirow distribution, and adjacent rows scraping teeth is dislocatedly distributed, and this structure is conducive to striking off and break up the fertilizer of stammerer on cylinder inboard wall completely, is further ensured that the treatment effect of stammerer fertilizer.
Four, in the present invention, multiple aperture pore more than fertiliser granulates external diameter it is provided with on described scraper plate, the fertilizer striking off and being broken up can fall to the bottom in cylinder by pore, it is to avoid the fertilizer broken up is piled up and phenomenon is occurred to extrude, and is conducive to improving product quality.
Five, in the present invention, the reason of fertilizer stammerer is that the moisture in fertilizer is more, and the moisture in fertilizer of stammering especially will be more than the moisture of fertilizer of not stammering, therefore, after stammerer fertilizer is broken up, electric heating tube and be electrically heated the scraper plate of pipe heating this part fertilizer can carry out redrying, and then can improve drying efficiency and the drying effect of fertilizer.
Six, in the present invention, described support column is internally provided with wiring channel, and the power line of described electric heating tube is connected up by wiring channel, and this structure, it can be avoided that power line is melted, is conducive to improving safety in utilization.
