Description

Technical Field

[0001] The utility model relates to the technical field of heat insulators, in particular to a heat insulation device for a mortar tank used in building construction. Background Art

[0002] Mortar is often used in the construction field. Mortar is mainly made of various lightweight materials as aggregates, cement as binder, and some modified additives. It is a premixed dry mortar made by stirring and mixing by the manufacturer. After the mortar is mixed, it needs to be loaded into a corresponding device (such as a barrel), and workers can take it out of the device when they need to use it.

[0003] After searching, a mortar tank insulation device for construction disclosed in the prior art (application number: CN202122064861.4) records that "a tank is fixedly installed on the upper end of the support seat, and an insulator is arranged inside the tank, and the insulator includes a first interface pipe, which is a circular pipe. The first interface pipe is arranged inside the support seat, and one end of the first interface pipe passes through the outside of the support seat, and the other end of the first interface pipe is fixedly connected to the first insulation pipe, and the end of the first insulation pipe away from the first interface pipe is fixedly installed with a connecting pipe, which is a circular pipe, and the end of the connecting pipe away from the first insulation pipe is fixedly connected with the second insulation pipe, and the end of the second insulation pipe away from the connecting pipe is fixedly connected with the second interface pipe, and the second interface pipe passes through the outside of the support seat, and a temperature measuring tube connected to the inside of the support seat is fixedly installed on the side of the tank, and a card slot is opened at the upper end of the tank, and a sealing device is arranged inside the card slot."; The insulation device allows the liquid inside the tank to be fully heated by the spiral pipeline of the first insulation pipe. The heating medium contacts the first insulation pipe and starts the insulation work. At this time, the heating medium keeps moving. When the heating medium passes through the second insulation pipe, the center of the tank is insulated. Through the first interface pipe and the second insulation pipe, the circulation time of the heating medium in the tank is prolonged, the contact area with the heating medium is increased, and the heating efficiency is improved. However, although the insulation device improves the heating efficiency and ensures the insulation effect of the mortar, the spiral pipe of the first insulation pipe and the second insulation pipe in a continuous "V" shape exist in a large area inside the tank, which will not only reduce the actual volume inside the tank, but also hinder the process of mortar feeding. Moreover, a large amount of mortar will remain on the insulation pipe, which will cool and condense after the device is on standby. Then, the insulation effect and the anti-residue effect of feeding are difficult to guarantee simultaneously. Moreover, the positions of the first insulation pipe and the second insulation pipe are fixed, and the position of the mortar after storage is also fixed, so that the mortar in some areas cannot obtain effective heat conduction and heat insulation, which will increase the probability of mortar condensation in this area.
