The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to accompanying drawing 1 to Fig. 4, there is the mixing drum that foam cement is used of preparing of dust arrester, comprise the cylindrical stirring cylindrical shell 2 of upper end open, stir cylindrical shell upper end and be installed with support cover plate 1, supporting cover plate seals 2/3 of stirring cylindrical shell upper end open, and the 1/3 not sealing of stirring cylindrical shell upper end open, convenient operation personnel observe the mixing situation that stirs raw material in cylindrical shell.Support on cover plate and there is charging aperture, the bottom of stirring cylindrical shell has discharging opening, discharging opening is provided with controls its unlatching or closed control valve 23, charging aperture is arranged on the top of stirring cylindrical shell, raw material enters from top to down and stirs in cylindrical shell, the process Raw of charging can carry out preliminary mixing, improves the efficiency of mix and blend;
On support cover plate, be also provided with dust arrester, dust arrester comprises exhaust tube 51 and aspiration pump 5, exhaust tube comprises bleed end and outlet side, and the end of bleeding stretches in stirring cylindrical shell through support cover plate and the end of bleeding is positioned at the top of stirring cylindrical shell, and outlet side is communicated with the gas access of aspiration pump; While entering in stirring cylindrical shell from top to bottom due to raw material; particulate tiny in raw material can be kicked up; dust arrester is taken away mixing the particulate of kicking up in cylindrical shell; prevent that on the one hand fine particle from raising out from stirring cylindrical shell upper end open; harm operator's is healthy, and also convenient operation personnel observe the stirring state that stirs raw material in cylindrical shell at any time on the other hand.
The madial wall of described stirring cylindrical shell is provided with multi-turn stock guide 4(vertically while specifically implementing, and two circles are set), on every circle, there is the setting of mutually staggering of multiple stock guides in multiple stock guides and two adjacent rings; In the time that the quantity of stock guide is greater than 5, the benefit that even mixing is brought increases not obvious, but has increased on the contrary generation and maintenance cost, therefore, and best uniform 3 ~ 5 stock guides on every circle.Due to stirring while adding raw material to stir in cylindrical shell, raw material normally adds several times, therefore, in the time that the material quantity adding in stirring cylindrical shell is less, be arranged on stirring cylinder inboard wall stock guide on the lower and play guide functions, in the time adding the material quantity stirring in cylindrical shell slowly to increase, be positioned at the top stock guide of stirring cylinder inboard wall and play guide functions, thereby improve stirring efficiency, and made to stir more even.
Stock guide is tri-prismoid structure, one, three faces of this tri-prismoid vertical direction are joint face, one is that while stirring, the face that is hit of raw material impact in cylindrical shell is stirred in acceptance, also having a face is supporting surface, described joint face is the cambered surface identical with stirring cylinder inboard wall radian and is fixedly connected with stirring cylinder inboard wall, described in the face of being hit be cambered surface; Joint face be arranged to the cambered surface identical with stirring cylinder inboard wall radian can be better with stir cylinder inboard wall laminating, thereby make stock guide fixing more firm, while receiving the impact of raw material in whipping process, can play better guide functions.For better, more easily connect, joint face circumferentially has to the connection edge of extending away from tri-prismoid direction, on connection edge, multiple threaded mounting holes are set, stock guide is fixed on well and is stirred on cylinder inboard wall through this threaded mounting hole by screw rod or bolt, make maintenance or change stock guide more convenient and quicker by screw rod or bolted mode.When stirring, accept to stir the face of being hit that in cylindrical shell, raw material impacts and be designed to cambered surface, increase the angle that stirs cylinder inboard wall and be hit between face, thereby prevent as much as possible in whipping process, affected mixing effect at stirring cylinder inboard wall and the formation stirring dead angle between face that is hit.Be hit and there are many row's hemispherical convex bodys 41 on face, on every row, there is the setting of mutually staggering of multiple hemispherical convex bodys on multiple hemispherical convex bodys and every row.When stirring, on shock surface, easily adhere to raw material, after mixing drum a period of time service time, on shock surface, tend to adhere to a lot of raw materials, therefore, many row's convex bodys are set on shock surface, the setting of mutually staggering of multiple hemispherical convex bodys on every row, can reduce whipping process Raw adhering on shock surface effectively, is convenient to clean material guiding parts, convex body is designed to hemispherical, the attachment surface of raw material becomes cambered surface, therefore, is more unfavorable for that raw material adheres to thereon, can also reduce like this loss of raw material, reduced production cost simultaneously; According to bionics principle, the setting of hemispherical convex body can also effectively reduce the flow resistance of raw material while stirring in addition, thereby reduces the load of motor, the service life of improving motor.
As optimization, the height of stock guide vertical direction is 40 ~ 50cm, and the intersection of be hit face and supporting surface is 15 ~ 20cm apart from the ultimate range of joint face, and the size of stock guide too greatly can increase cost, and too little water conservancy diversion effect is undesirable.As optimization, the area that the face that is hit that in cylindrical shell, raw material impacts is stirred in the acceptance of the stock guide on every circle from bottom to top increases successively.While working due to the stock guide of more top portion, illustrate that the raw material stirring in cylindrical shell is more, therefore, in the stirring cylindrical shell that stock guide on every circle is accepted from bottom to top, raw material impulsive force is larger, therefore, in order to bring into play better the effect of stock guide on every circle, the area that the face that in cylindrical shell, raw material impacts is stirred in the acceptance of the stock guide on every circle from bottom to top increases successively.When concrete enforcement, stir the too large raw material in it of the size of cylindrical shell at full capacity time, raw material is too many, easily produce the inhomogeneous problem that stirs, although it is more even to stir the too little stirring of size of cylindrical shell, production efficiency is very low, therefore the stirring size of cylindrical shell and the size of stock guide match, be preferably: the height that stirs cylindrical shell is 1.2 ~ 1.5m, the diameter that stirs the upper bottom surface of cylindrical shell is 0.6 ~ 0.65m.
When concrete enforcement, motor is arranged on and is supported on cover plate, stir in cylindrical shell and be also provided with the puddler that extends to its underpart, the bottom of puddler is fixedly connected with multiple stirring vanes that are divergent shape, and motor driving puddler rotates, and realizes the stirring to stirring raw material in cylindrical shell, after stirring, add blowing agent, then open rapidly control valve, the batch mixing stirring in cylindrical shell is discharged by discharging opening.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
