Abstract

The utility model discloses a kind of cement protecting box, its key points of the technical solution are that including babinet, air intake device, the air intake device includes pump machine, and rack is equipped in the babinet, it is characterised in that：The air intake device further includes aspiration channel, and the aspiration channel is attached at babinet, and the oral area of the aspiration channel is equipped with flow deflector, is set between the flow deflector and rack in angle.When pump machine air draught, air-flow enters aspiration channel from the oral area of aspiration channel, due to being equipped with the flow deflector of angle setting, gas is under the action of flow deflector, the oblique flow between horizontal plane, if the air-flow of the such oblique flow of carried interest can make up circulating current, so that the air-flow in babinet close to air draught spout part flows faster, flow bigger, and the air-flow of babinet center section is relatively stable, since cement briquette is positioned over babinet centre position, therefore the air-flow velocity at cement briquette can be reduced more, be not easy cement briquette surface dry and cracked.

Description

A kind of cement protecting box

Technical field

The utility model is related to the maintenance of equipment of cement experiment room, more particularly to a kind of cement protecting boxes.

Background technology

Cement briquette generally use cement protecting box carries out standard curing.In order to keep the water content of cement briquette, need to Aqueous gas is sprayed into cement protecting box, and after spraying into gas, it, again will be original in babinet in order to keep the in vivo air pressure of case Gas discharge.

At present, the Chinese patent of Publication No. CN206317216U discloses a kind of cement protecting box, it includes placing water The main box of mud test block is embedded with to absorb in curing box cement briquette at the top of main box caused by maintenance processes The air draught part of steam.At work, the in vivo air-flow of entire case is siphoned away for air draught part.

During the air draught part air draught of this cement protecting box, the entire in vivo gas of case is concentrated to stream at air draught part Dynamic, when air-flow flows through cement briquette, the air-flow velocity around cement briquette is accelerated so that the surface moisture of cement briquette is accelerated Evaporation, cement briquette surface are dry and cracked.

Utility model content

One purpose of the utility model is to provide a kind of cement protecting box, can reduce the dry and cracked possibility in cement briquette surface Property.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of cement protecting box, including babinet, air intake device, the air intake device includes pump machine, is equipped in the babinet Rack, it is characterised in that：The air intake device further includes aspiration channel, and the aspiration channel is attached at babinet, the aspiration channel Oral area is equipped with flow deflector, is set between the flow deflector and rack in angle.

By using above-mentioned technical proposal, when pump machine air draught, air-flow enters aspiration channel from the oral area of aspiration channel, due to setting There is the flow deflector that angle is set, gas is under the action of flow deflector, the oblique flow between horizontal plane, if carried interest so tilts stream Dynamic air-flow can make up circulating current so that the air-flow in babinet close to air draught spout part flows faster, flow bigger, and case The air-flow of body center section is relatively stable, since cement briquette is positioned over babinet centre position more, therefore can reduce cement briquette The air-flow velocity at place is not easy cement briquette surface dry and cracked.

Further set：The pump machine is located at the top of babinet, and the babinet is arranged to hollow housing, and the aspiration channel buries Enter the hollow layer of babinet, the oral area of the aspiration channel is equipped with air outlet, and the air outlet stretches out hollow space, is directed toward in babinet.

By using above-mentioned technical proposal, only have air outlet in babinet, can effectively reduce the occupancy to babinet internal volume Amount, makes that more cement briquettes can be accommodated in babinet.

Further set：The air outlet of the aspiration channel is arranged to duckbill.

By using above-mentioned technical proposal, after air port is arranged to duckbill, during air draught, suction bigger, to gas in babinet Carry out quick-replaceable.

Further set：The flow deflector is drawn from air outlet one end, is tilted and is directed toward in babinet.

By using above-mentioned technical proposal, the air-flow for being influenced by flow deflector and changing wind direction rapidly enters air outlet.

Further set：The flow deflector is divided into first group, second group, and first group and second group are led Flow is connected with same root aspiration channel.

By using above-mentioned technical proposal, same root aspiration channel can flow the air-flow at first group and second group Speed tends to be equal, and the in vivo air-flow of case is made to be not susceptible to turbulent flow.

Further set：The aspiration channel is equipped with multiple air outlets, is connected with out between the air outlet and aspiration channel Air hose.

By using above-mentioned technical proposal, discharge pipe makes air outlet for extending the distance between aspiration channel and air outlet The wall of babinet can be passed through.

Further set：First group is located in vertical inner wall, and second group is located in horizontal interior walls, water conservancy diversion The direction of piece is in set clockwise or counterclockwise.

By using above-mentioned technical proposal, the in vivo air-flow of case also forms circulation, ring in direction clockwise or counterclockwise The cement briquette of the center of stream is not easily susceptible to the influence of air-flow.

Further set：First group and second group are symmetrical arranged in the in vivo both sides of case, and symmetrical centre is case The perpendicular bisector of body bottom wall.

By using above-mentioned technical proposal, the flow direction of air-flow is along wall box, and the air-flow stream of the side-walls of both sides Speed tends to be equal, does not easily cause turbulent flow.

Further set：First group and the direction of the flow deflector in second group are on the contrary, deviate from babinet bottom wall Perpendicular bisector set.

By using above-mentioned technical proposal, the air current flow direction of both sides side-walls is not on the contrary, easily cause both sides air-flow pair Rush the turbulent flow formed.

Preferably, the in vivo rack of case is located at the surface of first group and second group joint.

By using above-mentioned technical proposal, air-flow is in flow process, since amount of flow maximum is placed exactly in first The intersection of group and second group, therefore place and be placed on the flowing that can obstruct air-flow herein and influenced caused by cement briquette.

In conclusion the utility model has the advantages that：

1st, cement briquette is small by the possibility on air-flow drying surface in babinet；

2nd, air-flow flows, and muddy gas original in babinet is changed away so that the in vivo environment of case is suitable for maintenance cement Test block.
