[0002] In industrial production, especially thermal power generation, chemical industry and metallurgy, flue system is a key component, used for discharging high-temperature flue gas. These flues are extremely susceptible to erosion and damage under the dual effects of long-term high temperature and corrosive environment. In order to protect the flue and prolong its service life, it is necessary to use erosion-resistant insulation materials on the inner wall of the flue.

Therefore, there is an urgent need for a heat insulation material quantitative filling equipment special for erosion resistant flue.

After filling is completed, there is often material residue in the quantitative cylinder, causing waste of heat insulation material. SUMMARY

[0005] In view of the above problems, the utility model discloses a kind of heat insulation material quantitative filling equipment special for erosion resistant flue.

The bottom end of the quantitative cylinder is provided with a quantitative device.

[0008] The bottom end of the quantitative cylinder is provided with a plurality of expansion zones and a plurality of reduction zones, and each of the expansion zones and each of the reduction zones is distributed at intervals. Each reduction zone is provided with a one-way valve.

[0009] Further, the installation main frame is provided with a through hole corresponding to the quantitative cylinder, and the through hole is provided with an annular mounting cylinder for fixing the quantitative cylinder.

[0010] Explanation: the through hole is provided with an annular mounting cylinder for fixing the quantitative cylinder, which improves the installation stability of the quantitative cylinder and avoids filling position error caused by position deviation of the quantitative cylinder.

[0011] Further, the installation main frame bottom end is equipped with a filling placement disc, the filling placement disc bottom end is connected with a rotating motor through a rotating shaft, and the filling placement disc upper end is uniformly equipped with a plurality of limiting discs along the circumference.

[0012] Description: When the heat insulation material in the storage container falls through the filling head to the external filling cylinder, the rotating motor drives the filling placement disc to rotate, so that two limiting discs distributed along the circumference are located at the bottom end of the corresponding filling head, precise positioning is realized, the stability and efficiency of the filling process are ensured, the need for manual adjustment is reduced, and the production line which needs a large amount of continuous filling is suitable.

[0013] Further, the distance between the two limiting discs distributed oppositely is equal to the distance between the two quantitative cylinders.

[0014] Description: The purpose of limiting the distance between the two limiting discs distributed oppositely to be equal to the distance between the two quantitative cylinders is to ensure that when the two filling heads simultaneously fill, they can accurately fall into the external filling cylinder placed in the corresponding limiting disc, precise filling is realized, and heat insulation material waste is avoided.

[0017] The beneficial effects of the utility model are as follows:

[0018] This utility model discloses a quantitative filling device for anti-corrosion flue gas insulation material. In use, the insulation material is added to each quantitative cylinder via a Y-shaped connecting pipe. The filling amount is detected by a metering device to ensure a constant amount of material flowing into the quantitative cylinder per unit time. Finally, the material is filled into the corresponding external filling cylinder through the filling head. This process completes the quantitative and batch filling of the insulation material, accelerating the filling process and improving filling accuracy. Simultaneously, as the insulation material passes through the quantitative cylinder, it sequentially passes through each expansion zone and each contraction zone from top to bottom before being filled into the corresponding external filling cylinder through the filling head. When the metering device detects that the insulation material filling amount has reached the preset value, it first closes the top one-way valve to prevent the continued addition of insulation material from the source, thus preventing more insulation material from entering and ensuring that the filling amount does not exceed the preset value, thereby achieving precise material control. Then, it closes the subsequent one-way valves in sequence, which helps to relieve the internal pressure of the material at the end of filling and prevents material backflow or overflow caused by the sudden closure of all valves, maintaining the stability of the system. At the same time, it helps to release the insulation material in the metering cylinder as completely as possible, reducing the amount of insulation material residue in the metering cylinder and reducing insulation material waste.
