Drying equipment and screening equipment are integrated, sand is added into the device to be automatically dried and screened, the equipment cost is lowered, and the production procedure is simplified.

Description

A kind of sand dries screening plant
Technical field
The present invention relates to premixing mortar production device technical field, be specifically related to a kind of sand and dry screening plant.
Background technology
At present, in premixing mortar production process, the sand that moisture content is suitable could meet the normal use of premixing mortar production line, sand is dried and is usually adopted drying roller, and in premixing mortar production process, the sand only having particle diameter qualified could use, therefore additionally must increase by one sieving circuit bulky grain sand in sand after oven dry is screened out, usually independently drying plant and screening installation is adopted in existing premixing mortar production process, the equipment cost not only greatly increased, increase use cost, and make the technological process of production complicated.
Summary of the invention
A kind of sand is the object of the present invention is to provide to dry screening plant, to solve drying plant and screening installation is relatively independent causes the problem that equipment cost is high, technological process is complicated.
For reaching above-mentioned requirements, the technical scheme that the present invention takes is: provide a kind of sand to dry screening plant, and this sand is dried screening plant and comprised drying chamber and be positioned at the screening room be communicated with below drying chamber and with drying chamber; Drying chamber top is provided with sand inlet and air outlet, and drying chamber lower sides is provided with air intake vent, in drying chamber, two opposing sidewalls is staggeredly equipped with downward-sloping ventilative close net; Rough sand outlet and fine sand outlet is provided with bottom screening room, screening is provided with sieve nest and vibrating motor in room, sieve nest comprises and is positioned at screen cloth that upper strata is obliquely installed and is positioned at lower floor and the deflector contrary with screen slope direction, screen cloth is all connected with the two ends of deflector, screen cloth is contrary with immediate ventilative close net incline direction, rough sand outlet is positioned at the below of the less one end of screen cloth and deflector gap, and fine sand outlet is positioned at the below of the larger one end of screen cloth and deflector gap, and vibrating motor is connected with deflector.
Further, screen cloth and deflector gap are provided with shut between less one end, and screen cloth and deflector gap are provided with support bar between larger one end.
Further, shut, support bar and deflector are provided with the spring be connected with the room of screening.
Further, ventilative close net is at least provided with 3.
The advantage that this sand oven dry screening plant has is as follows:
(1) drying plant and screening installation as a whole, sand add in this device can automatically complete dry and screening, reduce equipment cost, simplify production procedure;
(2) time of staying in the drying chamber of sand can be increased by the ventilative close net that is crisscross arranged, make oven dry more thorough;
(3) by arranging sieve nest and vibrating motor can make sand fully screen, ensure to produce sand particle diameter used qualified.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present application, form a application's part, use identical reference number to represent same or analogous part in the drawings, the schematic description and description of the application, for explaining the application, does not form the improper restriction to the application.In the accompanying drawings:
Fig. 1 is the structural representation of the application's embodiment.
Detailed description of the invention
For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.
In the following description, quoting of " embodiment ", " embodiment ", " example ", " example " etc. is shown that the embodiment of so description or example can comprise special characteristic, structure, characteristic, character, element or limit, but not each embodiment or example must comprise special characteristic, structure, characteristic, character, element or limit.In addition, reuse phrase " embodiment according to the application " although be likely refer to identical embodiment, and not necessarily refers to identical embodiment.
For the sake of simplicity, eliminate in below describing and well known to a person skilled in the art some technical characteristic.
According to an embodiment of the application, provide a kind of sand to dry screening plant, as shown in Figure 1, comprise drying chamber 3 and be positioned at the screening room 10 be communicated with below drying chamber 3 and with drying chamber 3; Drying chamber 3 top is provided with sand inlet 1 and air outlet 2, and drying chamber 3 lower sides is provided with air intake vent 11, and interior two opposing sidewalls of drying chamber 3 are staggeredly equipped with downward-sloping ventilative close net 4; Rough sand outlet 6 and fine sand outlet 9 is provided with bottom screening room 10, screening is provided with sieve nest 5 and vibrating motor 8 in room 10, sieve nest 5 comprises and is positioned at screen cloth 54 that upper strata is obliquely installed and is positioned at lower floor and the deflector 52 contrary with screen cloth 54 incline direction, screen cloth 54 is all connected with the two ends of deflector 52, screen cloth 54 is contrary with immediate ventilative close net 4 incline direction, rough sand outlet 6 is positioned at the below of screen cloth 54 and less one end, deflector 52 gap, fine sand outlet 9 is positioned at the below of screen cloth 54 and larger one end, deflector 52 gap, and vibrating motor 8 is connected with deflector 52.
