Abstract

The utility model relates to a concrete mixing station with the combination of internal and external mixing of a graded material feeding type, which comprises a raw material storage and supply part, a material distribution and conveying part, a mixer and a material discharge bucket, wherein the material discharge bucket is arranged below the mixer. The utility model is characterized in that the concrete mixing station is additionally provided with a stone material distribution and conveying device and a secondary water adding device, and the stone material distribution and conveying device and the secondary water adding device are both communicated with the material discharge bucket. The utility model is suitable for mixing concrete in the method of the combination of internal and external mixing of a graded material feeding type, not only greatly reduces the abrasion of the mixer and saves power consumption, but also enhances one time of the processing efficiency of pre-mixed concrete, and meanwhile, ensures the quality of the concrete.

Description

Mix the concrete mixing plant of combination inside and outside the step feeding

The utility model relates to the concrete mixing plant of mixing combination inside and outside a kind of step feeding.

In building industry, extensively adopt concrete mixing plant partly to form by raw material storage and material loading part, batching and batching transport portion, stirring blowing usually as the production equipment available coagulation soil mixing station of architectural engineering ready-mixed concrete, this concrete mixing plant is applicable to that the disposable alr mode that feeds intake is about to all drop into together in the mixer through the raw material that measures stir, and the concrete that stirs is dropped into trucd mixer by hopper be transported to the job site.Adopt the disposable alr mode that feeds intake owing to be whole raw materials especially stone all to be dropped in the mixer stir, therefore, exist the mixer quick abrasion, stir the not high enough problem of work efficiency.

Some studies show that, ready-mixed concrete can take to mix inside and outside the step feeding method of combination, the main feeding mode of this method is that mortar is stirred, stone and part water, water reducer are without mixer, directly drop into trucd mixer together, in trucd mixer, be mixed into concrete through hopper and the mortar that stirs.This method can not only significantly reduce the wearing and tearing of mixer, and can increase substantially the work efficiency of mixing plant, guarantees quality of concrete.

The purpose of this utility model is to provide a kind of being suitable for to mix the concrete mixing plant that associated methods uses inside and outside the step feeding.

The purpose of this utility model is realized by following technical scheme: include raw material storage and material loading part, batching and batching transport portion, mixer 8 and be installed in the hopper 4 of mixer below, its difference is to set up stone batching conveying device, and the discharging opening of stone batching conveying device is connected with hopper.

In the such scheme, stone batching conveying device can be made up of stone hopper 1 and conveyer belt 2

Main feature of the present utility model is to keep the basic structure of existing concrete mixing plant constant, set up stone batching conveying device, and roughing sand, building stones batching and conveying device are used as the batching conveying device of sand, can satisfy the demand of mixing inside and outside the step feeding like this in conjunction with processing mode.Good effect of the present utility model is: 1, because stone does not enter the mixer stirring, the ability that can make mixer stir mortar improves nearly one times, thereby can make the processing work efficiency on the premixing coagulation improve nearly one times, the material for the treatment of that so also can reduce trucd mixer connects material the time, improves the utilization rate of trucd mixer; 2, snap in the main cause that stone is its wearing and tearing between mixer lining board and the blade, only stir mortar prolonged the service life of mixer greatly; 3, stir the power consumption that mortar has also reduced mixer, can save energy more than 50%; 4, can guarantee quality of concrete, simultaneously, owing to kept the basic structure of original mixing plant, thereby according to circumstances the utility model still can be used to process the disposable concrete that feeds intake and stir, and makes it to possess the function of a machine dual-purpose.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the structure chart of water and water reducer scale bucket among embodiment of the utility model.

Fig. 4 is the structure chart of the utility model water and the another kind of structure of water reducer scale bucket.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include raw material storage and material loading part, batching and batching transport portion, mixer 8 and the hopper 4 that is installed in the mixer below, batching and batching transport portion include sand hopper 13 and sand chain bucket track 12, be arranged on the cement weigher bucket 14 and the admixture scale bucket 15 of mixer 8 tops, and a side is provided with above mixer water scale bucket 6 and water reducer scale bucket 7, water scale bucket and water reducer scale bucket are respectively by valve 19,17 are connected with mixer, can set up bucket and water reducer bucket respectively in a side of water scale bucket 6 and water reducer scale bucket 7 in addition, bucket of setting up and water reducer bucket are through

valve

18,16 merge into a pipeline enters middle water storehouse 9, the delivery port of middle water storehouse is connected with hopper 4 through pipe 11, above-mentioned set up bucket and the water reducer bucket can be integrally combined respectively with water scale bucket and water reducer scale bucket, as shown in Figure 3, also second water scale bucket 20 and second water reducer scale bucket 21 can be set independently respectively again, second water scale bucket and water reducer scale bucket are by

valve

18,16 are merged into one the tunnel is connected with hopper 4 through pipe 11, lower side at mixer is provided with stone batching conveying device, it includes stone hopper 1, but stone hopper belt scale, the discharging opening place of stone hopper sets a conveyer belt that is communicated with hopper 2, transfer hopper can be belt conveyor or high angle belt conveyer conveyer, also can be the lifting device that promotes the stone hopper, the delivery outlet of conveyer belt is connected by blanking groove 3 and hopper 4.
