Abstract
The utility model relates to pressure pre-wetting equipment for light-weight aggregate, which is a can-shaped, closed pressure vessel. A can body of the closed pressure vessel thereof is supported on a chassis of a concrete mixing haulage vehicle; an annular plate is welded around a discharge hole at the rear end of the can body; a pressure sealing cover covers the annular plate; the pressure sealing cover is provided with a bleed hole and a water injection hole; the bleed hole is connected with a deflation valve. A rubber packing is arranged on the contact face between the annular plate and the pressure sealing cover; corresponding screws are evenly distributed on the edges of the pressure sealing cover and the annular plate; the pressure sealing cover and the annular plate are fixedly connected with each other through a screw and a nut. The utility model has the advantages of simple structure, low manufacturing cost, rapid light-weight aggregate pre-wetting speed and high pre-wetting efficiency. The light-weight aggregate rapidly reaches the saturation water-uptake state in a shorter time, thereby being beneficial to lead the light aggregate concrete to realize the pumping.
Description
(1) technical field
The utility model relates to a kind of seal-off pressure container of construction material pre-processing device, particularly a kind of jar of shape.
(2) background technology
Lightweight, high-strength, durable be the developing direction of concrete technology, the development light aggregate concrete is to alleviate dead load, makes the main path of concrete to the development of lightweight, high-strength aspect.Light aggregate concrete was nearly 40 years of China research and application course, because the limitation of technology, economy and construction idea, this technology application space, range of application are restricted.In recent years, development and national economy has driven the fast development of building industry, especially the development of high level, high-rise building, marine structure, long span building and intelligent construction, characteristics such as light aggregate concrete is light with its dead load, good heat insulating, anti-seismic performance is good and fire resistance is good make it obtain unprecedented development space.But, because light-weight aggregate production technology and light aggregate concrete preparation, present situation of production technology and study limitation have restricted application, development and the popularization of light aggregate concrete.Therefore, extremely urgent to the research of the pumpability of light aggregate concrete and combination property.
At present, the light-weight aggregate method of prewetting is that light-weight aggregate is put into Nylon Bag, soaks, suction 24h the reach capacity 50%-60% of water absorption rate of water absorption rate.Light aggregate concrete, particularly unit weight is less than 2000kg/m
3The construction of light aggregate concrete generally be to adopt instrument such as suspension bucket to carry out vertical transport, do not have better method, such construction status has prolonged the construction period greatly, has increased the pollution and the waste of job site.So the solution of light aggregate concrete pumpability has been played key effect to promoting the concrete application.
(3) utility model content
The pressurization that the purpose of this utility model the provides a kind of light-weight aggregate equipment of prewetting will solve light-weight aggregate and prewet that speed is slow excessively, efficient is lower, the problem of pumpability difference.
For achieving the above object, the utility model adopts following technical scheme:
The pressurization of this light-weight aggregate equipment of prewetting, it is the seal-off pressure container of one jar of shape, it is characterized in that: the tank body 4 of seal-off pressure container is supported on the concrete mixing and transporting car chassis 1, be welded with a ring flat-plate 3 around the discharging opening of this tank body rear end, on ring flat-plate, be stamped pressurization lid 2, pressurization has covered air vent 10 and water injection hole 11, is connected with vent valve 6 on the air vent; On the contact-making surface between above-mentioned ring flat-plate and the pressurization lid rubber gasket 5 is arranged, be evenly distributed with corresponding screw 12 on the edge of pressurization lid and ring flat-plate, fixedly connected by screw rod 7 and nut 8 between the two.
Above-mentioned tank body discharging opening is connected with lubricating substance groove 9 downwards.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model is a kind of equipment that can pressurize and prewet light-weight aggregate, can utilize available coagulation soil stirring transport tank car to transform a little forms, the feed hopper of transport vehicle is removed, install the pressurization lid of band vent valve and water filling port additional, make tank body become a closed container that can carry out the pressure water filling.Have simple in structurely, cheap, the light-weight aggregate speed of prewetting is fast, the characteristics that the efficient of prewetting is high, and under pressure water action, the suction state but light-weight aggregate reaches capacity within a short period of time fast helps making light aggregate concrete to realize pumping.
Use the equipment of prewetting of the present utility model, having solved light-weight aggregate absorbs water in the pumping process and discharges water and influence the problem of pumping effect, using the method for the prewetting advantage that this equipment prewets more present is: one, speed is faster, and pressurization back 0-2h can finish the suction of light-weight aggregate; Two, efficient is higher, can the reach capacity 80%-90% of water absorption rate of the water absorption rate of light-weight aggregate.Through the concrete of the pretreated light-weight aggregate preparation of this equipment, can significantly improve the pumping construction performance of light aggregate concrete, expanded the range of application of light-weight aggregate.

(5) specific embodiment
Embodiment is referring to shown in Figure 1, the pressurization of this light-weight aggregate equipment of prewetting, it is the seal-off pressure container of one jar of shape, it is characterized in that: the tank body 4 of seal-off pressure container by two low early and high after seat supports on concrete mixing and transporting car chassis 1, be rotationally connected by drive disk assembly between two bearings and the tank body, be welded with a ring flat-plate 3 around the discharging opening of tank body rear end, on ring flat-plate, be stamped pressurization lid 2, pressurization has covered air vent 10 and water injection hole 11, is connected with vent valve 6 on the air vent; On the contact-making surface between above-mentioned ring flat-plate and the pressurization lid rubber gasket 5 is arranged, be evenly distributed with corresponding screw 12 on the edge of pressurization lid and ring flat-plate, fixedly connected by screw rod 7 and nut 8 between the two.Above-mentioned tank body discharging opening is connected with lubricating substance groove 9 downwards.
The course of work of the present utility model: light-weight aggregate is discharged in the tank body 4 by additive bin, and this moment, tank body was for just changeing.Light-weight aggregate accounts for 2/3rds of tank body greatly.Pressurization lid 2 is installed, and the screw 12 that ring flat-plate and pressurization are covered is relative, seals in screw rod 7 in the hole, and tighten with nut 8 at two ends, and this moment, vent valve 6 was an opening state.By pressure water valve water is squeezed in the tank body 4 by water filling port 11.After treating vent valve 6 water outlets, close vent valve, be forced into authorized pressure by water filling port 11.After treating to arrive pressing time, open the vent valve pressure release.Open pressurization lid 2, the tank body counter-rotating draws off the light-weight aggregate of prewetting through pressurization.
The pressure limit of this equipment tank body can be 1-8MPa, and the time set scope can be 0-2h, and volume is generally 6-10m
