Abstract
The utility model provides a feed device for a concrete mixing plant. The feed device comprises a stone hopper and a sand hopper, wherein the stone hopper and the sand hopper are arranged above a stirrer; a hopper-shaped storage slot of concrete admixtures is arranged between the stone hopper and the sand hopper; the lower end of the storage slot is right above the stirrer; and the upper end of the storage slot is provided with a folding door while the lower end of the storage slot is provided with a sliding door. By adopting the feed device, stone and sand are respectively metered by using a metering sensor, and concrete admixtures are accurately added into the stirrer through the open and close of the sliding door controlled by a cylinder, so that automatic metering and feeding of concrete materials are realized; not only is the dosage of the concrete admixtures accurately controlled, but also supervision and control are facilitated and personnel allocation is reduced.
Description
Technical field
The utility model relates to metering device technical field, is specifically related to a kind of feeding device of concrete mixing plant.
Background technology
In the downcast shaft construction of deep, colliery Jing Chu, needing with a large amount of concrete, is all to adopt Site site operation mode voluntarily to carry out in order to reduce transportation with facilitating site operation, its concrete.In well head east side, concrete mixing station is set, in standing, arrange that 2 JW1000 type forced action type concrete mixers and 1 cover PLD1600 type concrete proportioning machine carry out material loading, sand, stone and cement are all used micro-processor controlled self-measuring device to measure, hydromining measures with volumetric method, then adopting automatic defeated feed proportioning system to be transported to concrete mixer stirs, its error in dipping is controlled at and is less than 2%, and the concrete quality of preparation is good.
In concrete preparation process, in order to improve and to regulate concrete performance to need admixture Concrete Additive, comprise various water reducers, air entraining agent and pumping admixture, set retarder, early strength agent and accelerator etc., the addition of Concrete Additive is generally not more than 5% of cement quality.Although its importance is more and more subject to people's attention, the selecting of Concrete Additive, adding method and adaptability will have a strong impact on its development.At present the addition of Concrete Additive mainly adopts manually the metering according to previous experiences to add, and this outfits of on the one hand need to increase personnel working, manually adds on the other hand error greatly and be difficult to carry out Supervised Control.
Utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of feeding device of concrete mixing plant is provided, and realizes the automatic accurate metering to Concrete Additive, and reduces labour intensity.
In order to reach above-mentioned effect, the utility model provides a kind of feeding device of concrete mixing plant, comprise the stone hopper and the sand hopper that are positioned at mixer top, the centre of described stone hopper and sand hopper is provided with the accumulator tank of Concrete Additive, described accumulator tank is funnel-form, its lower end be positioned at described mixer directly over; The upper end of described accumulator tank is provided with folding door, lower end is provided with sliding door.
Further, described sliding door is connected with cylinder, and described cylinder is connected with magnetic valve by tracheae, and cylinder moves by solenoid control gas break-make, thereby drives the open and close of sliding door; Preferably the input of magnetic valve is connected to a relay, relay is connected energising again with electrical control cubicles.By relay being controlled to the power on/off time of magnetic valve, and then the motion frequency of control cylinder and time, realize the quantitative interpolation to Concrete Additive.
Further, described mixer is funnel-form, and its upper port two inner sides are arranged with the gage probe for measuring; The exit, lower end of described stone hopper and sand hopper is respectively provided with a belt toward middle operation, the discharge end of belt be positioned at described gage probe directly over.
Further, for fear of the loss of gage probe, described mixer both sides are respectively provided with two gage probes, and described gage probe is all electrically connected with electrical control cubicles.
During mixer work, stone, sand philosophy are metered into by gage probe, Concrete Additive is carried out accurate discharging by the open and close of cylinder control sliding door, together enter in mixer and stir, thereby it is reinforced to have realized the automatic gauge of concrete material with sand, stone.Not only more accurately control the consumption of Concrete Additive, and be convenient to Supervised Control, minimizing staffing.
This device is by making regular check on and proofreading and correct, making Concrete Additive add precision is effectively promoted, avoided artificial interpolation error large and be difficult to carry out the drawback of Supervised Control, reduced staffing, personnel labor intensity and Occupational Dust Hazard have been reduced, improved concrete for making quality, for safety in production, construction quality provide guarantee.From pit shaft, go into operation and use so far, it is all qualified that all concrete workses of construction are tested by sampling observation.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
