Abstract

A kind of method heated using residual heat from boiler fume to concrete agitation station river sand feed bin, is included the following steps:1. after the ground on smooth feed bin floor, interval pours multiple tracks concrete partition, it is discharge flue between partition wall, the exhaust smoke hole to pass through convenient for flue gas is laid on partition wall;2. one layer of insulating layer of asbestos is laid between partition wall;3. build the concrete bearing wall of Yi Ceng Hou Du≤25cm in partition wall top casting.Discharge flue is provided below in feed bin in this method, and feed bin floor is effectively heated when flue gas passes through, and heat again in time will be contained therein ice melting and keep the temperature by being conducted to river sand.

Description

The method heated using residual heat from boiler fume to concrete mixing station river sand feed bin
Technical field
It is more particularly to a kind of to utilize residual heat from boiler fume meeting coagulation the invention belongs to concrete mixing station constructive technology in winter The method of native mixing station river sand feed bin heating.
Background technology
In the north, large-scale or emphasis project under construction is ensures that the duration can carry out winter construction, and the production of concrete is The necessary guarantee that construction is normally carried out.But winter temperature is extremely low, and river sand water content can be freezed greatly and quickly in the short time It is not easy to melt.Material mouth can be frequently occluded if will directly freeze pockets of river sand and be packed into batch bin, match ratio is made to generate deviation, sternly Weight can even cause concrete to discard.Further, since being limited to the capacity of blending station storage bin, cannot once store too much, And its overlong time of thawing naturally, it is impossible to ensure continuous production, construction cost is caused to increase severely.Therefore, it is necessary to river sand is carried out Pre- thermal acceleration is melted, and ensures construction.
The content of the invention
The present invention provides a kind of method using residual heat from boiler fume meeting concrete agitation station river sand feed bin heating, the party Discharge flue is provided below in feed bin in method, feed bin floor is effectively heated when flue gas passes through, heat passes through biography in time again Leading will be contained therein ice melting and keep the temperature to river sand.
As above conceive, the technical scheme is that:It is a kind of to utilize residual heat from boiler fume to concrete agitation station river sand material The method of storehouse heating, it is characterised in that:Include the following steps:
It is discharge flue between partition wall, on partition wall 1. after the smooth ground in feed bin floor, being spaced and pouring multiple tracks concrete partition Lay the exhaust smoke hole to pass through convenient for flue gas;
2. one layer of insulating layer of asbestos is laid between partition wall;
3. build the concrete bearing wall of Yi Ceng Hou Du≤25cm in partition wall top casting.
The above-mentioned exhaust smoke hole quincunx laying on partition wall passed through convenient for flue gas.
The present invention has the advantage that and good effect:
1st, for the present invention after the smooth ground in feed bin floor, interval pours multiple tracks concrete partition, leads between partition wall for smoke evacuation Road, flue gas freely, does not stop along passage flow and the fever of feed bin bottom plate is uniform, feed bin floor is carried out when flue gas passes through effective Heating, heat again in time will be contained therein ice melting and keep the temperature by being conducted to river sand.
2nd, the present invention is laid with one layer of insulating layer of asbestos between partition wall, reduces heat and distributes, is effectively improved energy consumption Comprehensive utilization ratio.
3rd, the present invention make flue gas by discharge flue relatively long distance drift, reduce cigarette ash to aerial direct row High-volume, it is good for the environment.

Fig. 2 is heating system side view of the present invention;
Fig. 3 is heating system top view of the present invention.
In figure:1- feed bins floor;2- partition walls;3- insulating layer of asbestos;4- grounds;5- exhaust smoke holes;6- discharge flues.
Specific embodiment:
A kind of method using residual heat from boiler fume meeting concrete agitation station river sand feed bin heating includes the following steps:
1st, such as Fig. 1,2,3, after smooth ground, the short partition wall of C20 concrete of one of 30cm × 30cm is poured every 1 meter, and The quincunx square hole for laying 20cm × 20cm is as exhaust smoke hole.The interchannel stream that the boiler smoke of introducing can be formed between partition wall Lead to and the passage on side is flowed by square hole.
2nd, such as Fig. 2 is laid with one layer of insulating layer of asbestos between partition wall, can prevent that heat scatters and disappears and asbestos material has resistance to height Temperature, anti-corrosion, economy, it is effective the advantages that.
3rd, such as Fig. 1,2, concrete of a layer thickness not less than 25cm is built in short partition wall top casting, short partition wall also serves as load bearing wall.
Present system operational process is:Such as Fig. 3, it is boiler smoke flow path and process that arrow, which is indicated,.By pot After kiln gas introduces the discharge flue of feed bin lower part, flue gas diffuses in passage and passes through the square hole flow forward on partition wall, together When surge bin floor, floor conduct heat to again river sand make its temperature raise.After the passage of flow of flue gas to the end, It will always be discharged with channel attached chimney.
