Detailed Description
In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.
As shown in fig. 1, 2, 3 and 4, a concrete processing apparatus for building construction comprises a horizontal screw conveyor 1 provided with a multi-point feed inlet, a raw material stirring tank 3 communicated with a first feed inlet 9 at the front end of the screw conveyor 1, a discharge pipe 2 arranged at the tail end of the screw conveyor 1, a vibrating screen 5 communicated with a second feed inlet 10 of the screw conveyor 1, and a water spraying system 8 for adding water to materials in the screw conveyor 1.
The screw conveyor 1 is used for mixing and transporting various raw materials and materials, and the materials piled at the lower part of the machine groove do not rotate along with the screw body due to the gravity of the materials and the friction force between the materials and the machine groove, but only move forward under the pushing of the rotating screw blade, so that the purpose of conveying the materials is achieved as if a non-rotating nut does translational motion along the rotating screw rod. Because the screw conveyor 1 is convenient for multi-point loading and unloading, the mixing and stirring functions can be simultaneously completed in the conveying process of the embodiment. For example, when the rotating shaft rotates, the materials are acted by the normal thrust of the helical blades, and the radial component force of the thrust and the friction force of the blades on the materials possibly carry the materials to rotate around the shaft, but the materials do not rotate together with the helical blades due to the gravity of the materials and the friction force of the trough on the materials, and move along the axial direction of the trough under the action of the axial component force of the normal thrust of the blades. In the present utility model, the screw conveyor 1 body is provided in a conventional structure such as a driving device, a coupling, a housing, a discharge port, a rotary screw shaft, an intermediate hanging bearing, a support, a feed port, and the like.
In a specific implementation, the raw material stirring tank 3 is used for stirring a cementing material (such as cement) and a granular aggregate such as aggregate, so that a block structure formed in the transportation and storage processes is broken up, and the subsequent treatment is facilitated. The raw material stirring tank 3 is internally provided with a stirrer, an outlet pipe of the stirrer is in sealing connection with a first feed inlet 9 of the screw conveyor 1, and a first discharge valve 4 is arranged on the outlet pipe. The first discharge valve 4 adopts a star-shaped discharger which is suitable for the up and down of granular materials. The star discharger is composed of a rotor impeller with a plurality of blades, a shell, a sealing element, a speed reducer, a motor and the like, and the star discharger plays a role in conveying materials by virtue of the rotating impeller and plays a role in sealing, so that the star discharger can uniformly and continuously feed the spiral conveyor 1.
In the construction of building construction, concrete in situ is an indispensable process, and common concrete is basically cement + aggregate + water, and in order to improve properties of concrete such as accelerating hardening, improving strength and durability characteristics, reducing corrosion to reinforcing steel bars, etc., or concrete in different areas, locations needs different characteristics such as heat preservation, vibration prevention, sound insulation, etc., additives are added when concrete is mixed, and most of the additives are materials in powder form and are added to the concrete to impart characteristics to the concrete which are not available for certain common concrete mixtures, such as accelerators, air entraining agents, binders, corrosion inhibitors, retarders, plasticizers, crystallization additives, accelerators, etc. In normal use, the admixture is used in an amount of less than 5% of the mass of cement and is added to the concrete during batching/mixing. Since the admixture is small in amount and is mostly in powder form, it affects mixing performance when mixing with concrete due to the following defects such as uneven particles, agglomeration of the admixture, etc. Therefore, the vibrating screen 5 is arranged in the utility model and is used for vibrating and screening various additives, breaking up agglomerates and forming powder with uniform particles, the tail end of the vibrating screen 5 is provided with a discharging pipe which is in sealing connection with and then is communicated with the second feeding port 10 of the screw conveyor 1, the discharging pipe is provided with the second discharging valve 6, and the second feeding port 10 is arranged behind the first feeding port 9. The second discharge valve 6 adopts a star-shaped discharger which is suitable for drying powdery and small granular materials, and can prevent the leakage of additive dust and cause environmental pollution and material waste while uniformly and quantitatively conveying the materials.
The vibrating screen 5 adopts an ultrasonic vibrating screen, so that the agglomerated additive can be efficiently and rapidly scattered, the material with uniform particles can be screened out, the characteristics of the screened material are ensured to be unchanged, and in addition, the screen is effectively prevented from being blocked.
The water spraying system 8 comprises a water conveying pipe 801 arranged outside the screw conveyor 1 and a plurality of rows of water spraying nozzles 802 hung on the inner wall above the screw conveyor 1, wherein the water conveying pipe 801 is communicated with the water spraying nozzles 802 through branch pipes penetrating through the shell of the screw conveyor 1. Each row of water nozzles 802 comprises a plurality of water nozzles and is annularly and uniformly distributed on the inner wall above the screw conveyor 1.
The water nozzles 802 of each row are connected in parallel, and the water pipe 801 is provided with a plurality of groups of control valves 803 which are positioned between the two rows of water nozzles and used for controlling the closing and the communication of channels leading to the water nozzles 802 of each row, thereby controlling the opening quantity of the water nozzles 802. The water spray nozzle 802 is installed at the rear of the second feed inlet 10 with a distance therefrom.
A baffle 7 is provided between the foremost nozzle 802 and the second inlet 10 to avoid adverse effects of liquid on front-end material mixing during water injection. The baffle 7 is a semi-annular arc plate and is fixed in the inner wall of the screw conveyor 1, and the baffle is semi-annular, so that the upper part and the lower part of a corresponding area in the barrel of the screw conveyor 1 are communicated, and the conveying of materials is not influenced.
