Problems solved by technology

When igniting, first ignite the cotton thread to ignite the wrapping paper, and then ignite the adobe mixture in the wrapping paper. Since most of the wrapping paper that is ignited first is above the adobe mixture, it cannot effectively preheat the adobe mixture. Therefore, the traditional adobe The way the mixture is wrapped makes it difficult to burn it completely
Since the calorific value of the adobe mixture is very low, generally around 300KCa / Kg, and cannot be completely burned, the measured calorific value has a large error, which cannot guide the normal production of brick and tile enterprises.

Embodiment 1

[0013] As shown in Figure 2, the spherical wrapping method for measuring the calorific value of the brick adobe mixture is: first spread out the wrapping paper 1, and what wrapping paper is used in this embodiment is square paper, and circular paper can also be used; Place the brick adobe mixture 2 at the center of the wrapping paper 1, fold the wrapping paper in half diagonally, then tighten the upper part of the wrapping paper wrapped with the brick adobe mixture after folding in half, and finally tighten the wrapping paper after the upper part is tightened Tie up the top with cotton thread 3 and get final product after being folded down.

[0014] Put the bundled adobe mixture into the oxygen bomb according to the conventional heat value measurement method, and fill it with oxygen to burn. After testing, the error is ±8 kcal, and the error is within the range of ±20 kcal stipulated by the state.

Embodiment 2

[0016] As shown in Figure 3, the roll-up wrapping method is to fold the wrapping paper 1 with the brick adobe mixture 2 horizontally in half and fold it into a roll, then fold it from both ends to the middle, and then tie it tightly with cotton thread 3 in the middle. .

[0017] Put the bundled adobe mixture into the oxygen bomb according to the conventional heat value measurement method, and fill it with oxygen to burn. After testing, the error is ±11 kcal, which is within the range of ±20 kcal stipulated by the state.

Abstract

The present invention is mixed adobe material packing method for heat value measurement, and belongs to the field of adobe material heat value measuring technology. The mixed adobe material packing method may be a ball packing method or a reel packing method. The ball packing method includes spreading packing paper, setting mixed adobe material in the center of the paper, folding the paper, tightening the upper part of paper package, and tying with cotton thread. The reel packing method includes transversely rolling the packing paper with mixed adobe material, folding the paper from two ends, and tying with cotton thread in the middle part. The present invention has the advantages of simple packing process and capacity of burning the mixed adobe material fully.

Description

technical field [0001] The invention belongs to a method for measuring the calorific value of a brick adobe mixture, in particular to a wrapping method for measuring the calorific value of a brick adobe mixture. Background technique [0002] The method for measuring the calorific value of the adobe mixture is: weigh a certain amount of adobe mixture, wrap it in wrapping paper and tie it with cotton thread, put it into a porcelain crucible with asbestos pads, and then put it into an oxygen bomb filled with a certain amount of water. , charged with excess oxygen for combustion. After burning, the heat is absorbed by the water, and then the calorific value of the tested adobe mixture is calculated according to the change of the water temperature. The traditional wrapping method of brick adobe mixture is as follows: as shown in Figure 1, first spread out the wrapping paper, place a specified amount of brick adobe mixture in the center of the wrapping paper, ...
