Description

Material heat preservation device for building construction

Technical Field

The invention relates to the technical field of preservation of building materials, in particular to a material heat preservation device for building construction.

Background

The building construction refers to the production activity of engineering construction implementation stage, which is the construction process of various buildings, namely the process of changing various lines on a design drawing into real objects at a designated place, a large amount of building materials are used in construction, concrete is one of the building materials with the largest usage amount, and if the concrete prepared in the construction process is not stored in a heat-insulating way, the water in the concrete is gradually solidified at low temperature, so that heat-insulating equipment is needed when the prepared concrete is stored.

Through retrieving, the patent of publication number CN212528187U discloses a concrete heating heat preservation section of thick bamboo, through the heating heat preservation device that sets up in the outside of concrete processing equipment body, be convenient for through TC200 heating controller control heating pipe rapid heating, with concrete heating preservation, through the rubber and plastic heat preservation cotton that sets up at the heating pipe outer end, asbestos net heat preservation and aluminium foil heat preservation, can prevent that the temperature from losing, through motor shaft and the (mixing) shaft that sets up in the inside of concrete processing equipment body, can be efficient through driving motor control rotation stirring.

The feed inlet of current device is open-type structure, and so the heat just can distribute to outside from this, will make the device need consume more electric power in order to reach inside heat preservation effect, moreover, current device is harder to control the discharge volume of concrete through the method of discharging the concrete with the mode of discharging plate opening, and if the discharge plate is opened under the circumstances that need not all concretes in the device to discharge totally will make the heat in the device lose in a large number, the follow-up extremely big electric energy that will take and very much time just can be with the inside temperature of the device rise to original temperature.

As another example, the disclosure of CN113320847a discloses a building construction material heat insulation device, through the heat insulation box, the first heat insulation layer, the inner box, the top cover, the second heat insulation layer, the installation box, the storage battery and the heating net are matched, the water-proof material of the water agent is prevented from being frozen in the transportation process under the condition of cold weather, and the water-proof material of the water agent is prevented from being toppled over in the transportation process by stacking the water-proof material of the water agent in the inner box, thereby being convenient for loading and unloading.

The existing device can only perform heat preservation and heating effects on the material closest to the heating net in use, can absorb heat in a close range and attenuate in the heat conduction process, and can cause cold solidification of the material far away from the heating net when the weather is extremely cold, and the device is only suitable for preserving fluid building materials after barreling and has high limitation; in addition, in the concrete heat preservation device in the prior art, although the rotating equipment is arranged to keep the fluidity of the concrete in the concrete heat preservation device, an outward power mechanism is still needed in the process of taking out the concrete, and the cover plate of the heat preservation barrel is required to be opened, so that the heat preservation performance is greatly reduced, especially in extremely cold areas, the construction operation is limited, and therefore the volume and the weight of the whole concrete heat preservation mechanism are large.
