Description
Technical field
The utility model relates to a kind of dry sand intermediate bin, especially a kind of dry sand intermediate bin that can be used for various dry-mixed mortar plants.
Background technology
In the dry-mixed mortar plant running, the conveying of dry sand and metering are to guarantee one of key of production efficiency and dry-mixed mortar quality.At present, people generally adopt bucket elevator that the dry sand material is directly inputed to the dry sand metering device, do like this to produce greater impact when on the one hand entering metering device because of dry sand and cause measuring accuracy poor, on the other hand, can cause the bucket elevator Fraquent start and stop, influencing its dependability.For this reason, have and adopted the dry sand intermediate bin on the minority dry-mixed mortar plant, played certain effect, but because the intermediate bin memory space that is adopted is little, the size that the measuring accuracy of dry sand material is low, can not control its rate of discharge, mobile relatively poor etc. in the storehouse of the performance of the anti-dry sand grinding abrasion of warehouse and dry sand, also just can not solve the existing problem of intermediate bin of not establishing traditionally well, and because warehouse geometry and selection unreasonable makes that its dependability is poor, service life is shorter.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, measuring accuracy height, reliability height, the dry-mixed mortar plant dry sand intermediate bin of long service life.
For achieving the above object, the utility model dry-mixed mortar plant dry sand intermediate bin comprises feed pipe, warehouse, and discharge nozzle, described feed pipe is obliquely installed, and its horizontal sextant angle is 50 °～60 °; The rectangle enclosed cavity of the top of warehouse for being welded by steel plate, the twin-bucket cone of warehouse bottom for being welded by the polylith steel plate, its top and the bottom connect as one by welding manner, be welded with one in the lower end on warehouse top and be used to reinforce warehouse, and be used for the square set of sensor installation, whole warehouse by square set and a plurality of sensor support on underframe, two exits of twin-bucket cone are connected with little discharge nozzle and big discharge nozzle respectively, be provided with associated blowing Pneumatic butterfly valve in the little discharge nozzle mouth of pipe, be provided with associated blowing Pneumatic butterfly valve in the big discharge nozzle mouth of pipe.
Described a plurality of sensor is three, evenly arranges; Described warehouse top is respectively equipped with venthole and manhole; The caliber of described big discharge nozzle is about 300mm; The caliber of little discharge nozzle is about 200mm.
Beneficial effect: the utility model adopts sensor to carry out real time measure, opening, stopping and the open and close of two blowing Pneumatic butterfly valves by the procedure auto-control elevator, and the angle of inclination and the warehouse conical surface angle of feed pipe be optimized, make that the accurate measurement of dry sand material is reliable, effectively avoided the frequent starting of elevator, the flowability of dry sand in feed pipe and storehouse improves, thereby improves operating efficiency, reliability and the dry-mixed mortar quality of dry-mixed mortar plant, also reduced energy consumption simultaneously.Improve the quality of finished product dry-mixed mortar; Reduce energy consumption, improve the equipment dependability, can be used for the dry-mixed mortar plant of various models.It is simple and reasonable, the measuring accuracy height, and the reliability height, long service life, result of use is good.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: the 1-feed pipe; The 2-venthole; The 3-manhole; The last reinforcing of 4-shaped steel; 5-reinforces shaped steel down; The 6-warehouse; The 7-support; The 8-sensor; The 9-underframe; The little blowing Pneumatic butterfly valve of 10-; The little discharge nozzle of 11-; The big blowing Pneumatic butterfly valve of 12-; The big discharge nozzle of 13-.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
As shown in the figure, the utility model dry-mixed mortar plant dry sand intermediate bin, warehouse 6 is a sealed hollow, rectangular structure for being welded into around the top by 4 block plates, welded top has a cover plate, on the cover board is provided with feed pipe 1, and be provided with venthole 2 and manhole 3, feed pipe 1 is obliquely installed, and its horizontal sextant angle is 50 °～60 °, and feed pipe 1 top is flexible coupling by woven belt and elevator.The twin-bucket cone of warehouse 6 bottoms for being welded by the polylith steel plate, each surface of cone angle of vertical line relatively is 35 °～38 °; The top and the bottom of warehouse 6 connect as one by welding manner, are welded with one in the lower end on warehouse top and are used to the square set 7 reinforcing warehouse and be used for sensor installation, and whole warehouse is supported on the underframe by square set 7 and a plurality of sensor 8; A plurality of sensors 8 are three, evenly arrange.Two exits of twin-bucket cone are connected with little discharge nozzle 11 and big discharge nozzle 13 respectively, are provided with associated blowing Pneumatic butterfly valve 10 in little discharge nozzle 11 mouths of pipe, are provided with associated blowing Pneumatic butterfly valve 12 in big discharge nozzle 13 mouths of pipe.The caliber of big discharge nozzle 13 is about 300mm; The caliber of little discharge nozzle 11 is about 200mm.
During work, bucket elevator will be transported to by the feed pipe 1 of dry sand through being obliquely installed of drying machine drying among the inner chamber of warehouse 6, by the weight of dry sand material in the sensor 8 real time measure storehouses, and can be by intuitively showing on the controller panel in the control room; The hot gas that hot dry sand produced that enters among the warehouse 6 is discharged through the hole 2 of breathing.
When beginning weighing again after the dry sand weighing hopper is put into stirring host with the dry sand that measures, little blowing Pneumatic butterfly valve 10 and big blowing Pneumatic butterfly valve 12 are all opened blowing simultaneously; Deng metering is fast before finishing setting constantly, big blowing Pneumatic butterfly valve 12 is closed, only allow little blowing Pneumatic butterfly valve 10 continue blowings, when reaching the required dry sand amount of each stirring, it is closed fully by electric-control system.Open large and small two blowing Pneumatic butterfly valves simultaneously in the metering incipient stage, can improve dispensing speed, promptly reduce the First Astronautic Research Institute for Measurement and Test and take time, improve metering speed; Setting before metering will finish is closed big blowing Pneumatic butterfly valve constantly, only allows little blowing Pneumatic butterfly valve be held open, and this just can reduce the blowing amount, promptly reduces the impact of institute's blowing to weighing hopper, improves measuring accuracy.
Because the conveying capacity of elevator is greater than the required dry sand amount of mixer, then stored dry sand can increase gradually in the warehouse 6.When the sensor 8 indicated dry sand weight that are provided with reach 6 maximums that can store of warehouse, automatically elevator is closed down by electric-control system; In case when the dry sand weight in the indicated warehouse 6 of sensor 8 reached predefined minimum of a value, electric-control system can start elevator automatically and continue to carry dry sands to warehouse 6.
