小型混凝土攪拌車(chē)的攪拌筒攪拌葉片的設計一般以順時(shí)針轉動(dòng)作為進(jìn)料和攪拌，逆時(shí)針旋轉作為出料。進(jìn)料時(shí)攪拌筒的轉動(dòng)速度較快，為的是節省工作時(shí)間，攪拌時(shí)攪拌筒的轉動(dòng)速度較慢，為的是減少水分過(guò)快地蒸發(fā)，減少離析。下面就跟著(zhù)小編來(lái)了解更多內容吧。

The design of the mixing drum and mixing blade of the small concrete mixer generally adopts clockwise rotation as the feeding and mixing, and counterclockwise rotation as the discharging. The rotation speed of the mixing drum is fast during feeding, in order to save working time; the rotation speed of the mixing drum is slow during mixing, in order to reduce excessive evaporation of water and segregation. Let's follow Xiaobian to learn more.

但是在運輸的過(guò)程中攪拌筒須以恒定速度運轉，為的是使混凝土不凝固變質(zhì)。在筒體轉動(dòng)的過(guò)程中混凝土被葉片連續不斷地推送到攪拌筒的前部，到達前端的混凝土勢必又被攪拌筒的端壁頂推反轉回來(lái)，這樣混凝土做前后的翻滾運動(dòng)；

However, in the process of transportation, the mixing drum must be operated at a constant speed to prevent the concrete from solidifying and deteriorating. During the rotation of the barrel, the concrete is continuously pushed to the front of the mixing barrel by the blades, and the concrete reaching the front end is bound to be pushed back by the end wall of the mixing barrel, so that the concrete rolls back and forth;

兩條葉片不停的旋轉帶動(dòng)混凝土連續的旋轉，同一位置上的混凝土通過(guò)這種運動(dòng)發(fā)生連續不斷的變化，從而起到攪拌作用；另外，葉片形狀曲線(xiàn)型的變化可使混凝土在其根部與筒壁之間形成一個(gè)個(gè)小的循環(huán)運動(dòng)，對攪拌混凝土也起到了一定的作用。

The continuous rotation of the two blades drives the continuous rotation of the concrete, and the concrete at the same position changes continuously through this movement, thus playing a mixing role; In addition, the change of the blade shape curve can make the concrete form a small circular movement between its root and the cylinder wall, which also plays a certain role in mixing concrete.

當混凝土運輸到工作地點(diǎn)，攪拌筒將做逆時(shí)針旋轉，此時(shí)葉片的旋轉方向也相反，混凝土將會(huì )被葉片引導向攪拌筒口移動(dòng)，直從筒口卸出。

When the concrete is transported to the work site, the mixing drum will rotate counterclockwise, and the rotation direction of the blade is also opposite. The concrete will be guided by the blade to move to the mixing drum mouth until it is discharged from the drum mouth.

以前，混凝土罐體生產(chǎn)企業(yè)在螺旋葉片的安裝過(guò)程中，由于沒(méi)有使用優(yōu)化技術(shù)，沒(méi)有先在板料上噴粉畫(huà)線(xiàn)后切割卷圓，再沿著(zhù)卷圓在罐體上形成的螺旋葉片母線(xiàn)進(jìn)行安裝，而是完全憑工人的生產(chǎn)經(jīng)驗進(jìn)行焊接安裝，導致安裝完成后形成以螺旋線(xiàn)為母線(xiàn)的不合理的螺旋葉片，得到的罐體成形尺寸精度較差，進(jìn)而影響到了進(jìn)出料速度，使出料率較低。

In the past, in the installation process of spiral blades, concrete tank manufacturers did not use optimization technology. They did not spray powder on the plate first, draw lines, then cut the roll circle, and then install along the spiral blade generatrix formed on the tank body. Instead, they welded and installed it completely based on the production experience of workers, resulting in unreasonable spiral blades with spiral lines as generatrix after installation, resulting in poor dimensional accuracy of the tank body, Thus affecting the feeding and discharging speed and making the discharging rate low.

現在，通過(guò)對罐體螺旋線(xiàn)進(jìn)行參數化和優(yōu)化設計，可以?xún)?yōu)化坯料，并能通過(guò)數控準確下料，利用卷錐模完成罐體的卷錐成形，后利用CO2氣體保護焊完成整個(gè)罐體和葉片的焊接，完成罐體的成形。

Now, by parameterizing and optimizing the spiral of the tank body, the blank can be optimized, and the material can be accurately cut by numerical control. The cone rolling forming of the tank body is completed by the cone rolling die, and then the welding of the whole tank body and the blades is completed by CO2 gas shielded welding to complete the formation of the tank body.

對優(yōu)化工藝后成形的罐體進(jìn)行檢測和實(shí)驗，結果表明罐體的尺寸精度明顯提高并符合要求，罐體的出料率也明顯提高，符合標準。

The inspection and experiment of the tank formed after the optimized process show that the dimensional accuracy of the tank is significantly improved and meets the requirements, and the discharge rate of the tank is also significantly improved, which meets the national standard.
