The material sending set is provided with and is connected the below of weighing matching device; Realize material and Air mixing and pressurization in this material sending set, the wall of tank body is provided with air inlet pipe and pressure sensor and the corresponding valve of introducing gas-pressurized;
Pneumatic conveying pipeline is communicated in the material sending set and connects material and charging device; Pressurized material and gas are transported to through pipeline thus by a certain percentage and connect material and charging device and finally entering in the banburying equipment in this Pneumatic conveying pipeline, to realize long-range conveying; Pneumatic conveying pipeline adopts rubber braided tube material, withstand voltage to guarantee, wear-resistant and anlistatig operating needs;
Connect material and charging device, be communicated with Pneumatic conveying pipeline and banburying equipment, be fed in the banburying equipment with the material that will carry; This device comprises bonded assembly bag hose, splice jug and the skewed slot that feeds intake successively; In bag hose, pressure gas is discharged and material is stayed tank interior, thereby realizes separating material and pressure gas; In splice jug, the material of separating is kept in, and material is put in the banburying equipment by the skewed slot that feeds intake.
It more than is the described major programme that realizes the batching feedway of long-range weighing.
As the batching feedway of above-mentioned structure, be to be delivered to one or more banburying equipment from long-range by the material of Pneumatic conveying pipeline after with weighing.
Promptly from the material weighing proportioning, after through the material sending set material and pressurized air fully being mixed, carry along Pneumatic conveying pipeline, above banburying equipment connect material and charging device in temporary, and finally be delivered in one or more banburying equipment.
In material and the course of conveying of compressed-air actuated compound in Pneumatic conveying pipeline, have influence on the prescription precision for guarantee that material can not piled up in pipeline, make delivery duct can keep clean totally, guarantee the precision of feeding, further improvement project is,
In the inboard of Pneumatic conveying pipeline, be provided with several pressure sensors;
In the outside of Pneumatic conveying pipeline, an air by-pass pipe is set; On the inwall of Pneumatic conveying pipeline, be communicated with several air by-pass boosting washing equipments, air by-pass boosting washing equipment is communicated with respectively between Pneumatic conveying pipeline and air by-pass pipe, preventing that material from piling up, stopping up Pneumatic conveying pipeline because of gaseous tension reduces in course of conveying, and prevent that material from finishing afterwards residual in delivery duct carrying; This air by-pass boosting washing equipment comprises successively and running through filtering nozzle, check valve that is communicated with Pneumatic conveying pipeline and the connection pipe that is connected the air by-pass pipe;
When the gaseous tension in the Pneumatic conveying pipeline reduces and exceeds fence coverage, pressure sensor is with numerical value output and warning, then can pass through air by-pass boosting washing equipment this moment, charge into the gas of compression via the air by-pass pipe to Pneumatic conveying pipeline, to guarantee the required normal barometric pressure of convey materials.
Described filtering nozzle inserts in the support tube, and this support tube runs through the inwall that is communicated with described Pneumatic conveying pipeline, and support tube is connected with the outer wall of Pneumatic conveying pipeline by nut.
For improving material via the transmission performance of material sending set to Pneumatic conveying pipeline, between material sending set and Pneumatic conveying pipeline, be provided with one and send pilot piping, send pilot piping and be provided with shutoff valve, pressure regulating valve and filter etc., to realize controlling the action in proper order of each valve by the technological operation requirement.
Between Pneumatic conveying pipeline and charging device, be connected with change-over valve, to realize the centralized automatic blending feed mode of corresponding many Banbury mixeies of a cover weighing equipment.
Content to sum up, major advantage of the present utility model and beneficial effect are:
1, realized material, be delivered to the centralized batching feed mode of banburying equipment, helped solving the equipment mounting arrangements of production scene, effectively reduce civil engineering and equipment cost by Pneumatic conveying pipeline with long-range proportioning.
2, long-range mass transport is steadily reliable, can not have influence on the prescription precision, and production efficiency improves.
3, separate unit meausring apparatus degree of utilization height, overhaul of the equipments and maintenance cost are lower.
