攪拌一體車多數(shù)時間的施工條件比較惡劣,在生產(chǎn)過程中也會經(jīng)常出現(xiàn)一些缺點,如不能及時處理,將嚴重影響工程項目的施工進度與質(zhì)量。下面我們就來說說攪拌一體車運行出現(xiàn)抱軸現(xiàn)象的原因是什么。
Mixing vehicle most of the time the construction conditions are relatively bad, in the production process will often appear some shortcomings, such as timely treatment, will seriously affect the construction progress and quality of the project. Here we say what is the reason for the phenomenon of holding the axle in the operation of the mixing vehicle.
攪拌一體車的投料裝置設(shè)計的不合理。如水泥和粉煤灰進料口位置及方向不合理,導(dǎo)致粉料很大一部分投放到軸上,以致粘結(jié)在軸上形成“抱軸”現(xiàn)象。沖水點的位置和沖洗方向不正確,或者沖水壓力過低。
The design of feeding device of mixing vehicle is unreasonable. Such as cement and fly ash feed port location and direction is not reasonable, resulting in a large part of the powder into the shaft, so that bonding on the shaft to form a “holding shaft” phenomenon. Flush point position and flush direction is incorrect, or flush pressure is too low.
在沖洗罐內(nèi)時,攪拌裝置上粘著的混凝土沖洗不掉,形成“抱軸”現(xiàn)象。攪拌筒的容積利用率的大小不合理,容積利用率太小將使攪拌軸暴露在混凝土上面,粘附在上面的一部分混凝土將得不到攪拌而凝固在軸上形成“抱軸”現(xiàn)象
When washing the tank, the concrete stuck on the mixing device can not be washed off, forming the phenomenon of “holding the shaft”. The volume utilization ratio of the mixing cylinder is unreasonable, and the volume utilization ratio is too small to expose the mixing shaft to the concrete, and the part of concrete adhered to above will not be stirred and solidified on the shaft to form the phenomenon of “holding the shaft”
為了使混凝土不發(fā)生離析現(xiàn)象,攪拌葉片線速度應(yīng)受限于攪拌臂外端的大值。這樣,在靠近攪拌軸的一端,由于線速度相對較低,就形成了攪拌低效區(qū)甚死區(qū)。
In order to avoid concrete segregation, the linear velocity of the mixing blade should be limited to the maximum value of the outer end of the mixing arm. In this way, at one end close to the mixing shaft, low efficiency zone or even dead zone is formed due to relatively low linear velocity.
同時,隨著攪拌機容量的增大,其攪拌筒半徑尺寸就要比攪拌葉片的高度大得多,因此當攪拌軸轉(zhuǎn)動時,葉片只能攪動靠近拌筒內(nèi)壁的一層物料,料層高即為葉片的高度,而處于攪拌葉片和攪拌軸之間的很大一段距離的物料將無法得到很好的攪拌。
At the same time, with the increase of capacity of mixer, the mixing cylinder radius size is much larger than the height of the mixing blade, so when the stirring shaft rotational blade can only stir up close to add a layer of material for the inner surface of cylinder, the height is the height of the blade, and stir in a big distance between the blade and the stirring shaft materials will not be able to get good agitation.
顯然,此時攪拌低效區(qū)問題就更嚴重。低效區(qū)內(nèi)混合料運動緩慢,各相間的對流、滲透作用不劇烈,容易使混合料粘附在攪拌軸上,形成“抱軸”現(xiàn)象。
Obviously, at this time, the problem of low efficiency mixing zone is more serious. In the low-efficiency area, the mixture moves slowly, and the convection and infiltration of each phase are not intense, which makes the mixture adhere to the mixing shaft easily and form the phenomenon of “holding the shaft”.
