Embodiment 1

[0042] Such as figure 1 with figure 2 As shown, the on-line detection device for lime burning degree includes a frame 1, a reaction vessel 10 and a load cell 2. The reaction vessel 10 is used to hold lime samples, and the load cell 2 is used to measure the weight of the reaction vessel. The heavy sensor 2 is supported and installed on the rack 1 .

[0043] The frame 1 includes four uprights 11, the four uprights 11 are arranged in four different directions at intervals, each upright 11 extends along the up and down direction, and the middle parts of the two uprights 11 arranged in the same plane are fixedly connected by a cross bar 12 , the top of each column 11 is provided with a cover plate 13 , the cover plate 13 forms a complete frame 1 together with the column 11 and the cross bar 12 .

[0044] The top of the cover plate 13 is provided with a feed pipe 9 and lifting screws 5 at intervals, and the lifting screws 5 are fixedly connected with the cover plate 13, so that the...

Embodiment 2

[0057] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, a stirring shaft 41 is provided in the filter screen 100, a drive motor 4 is provided on the cover plate 13, and the drive motor 4 drives the stirring shaft 41 to rotate to accelerate lime Sample response. However, in this embodiment, no stirring shaft is installed in the filter screen, and the drive motor is canceled at the same time, and the drain valve is in a normally open state at this time, and water is always added to the filter screen until the lime sample is fully reacted, and the sample residue and reaction are measured. The total weight of the container G 2 .

Embodiment 3

[0059] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the drain valve 7 is hoisted below the reaction vessel 10 through the drain pipe 71 . In this embodiment, a drain valve seat is provided on the frame, and a drain valve is supported on the support of the drain valve seat, and the drain valve communicates with the drain port through a flexible pipe.

Abstract

The invention relates to a lime underfiring degree on-line detection device, comprising: a rack which is equipped with a weighing sensor and a reaction container supported on the rack through the weighing sensor; a filter screen which is arranged in the reaction container and divides the space in the reaction container into two parts, one part being a sample space for adding a lime sample, the other part being a filtrate space for allowing filtrate generated after the reaction of the sample and water to enter, and the sample space being communicated with the filtrate space through filter holes in the filter screen; a sample feeding hole which is communicated with the sample space and is used for adding a lime sample into the sample space; a water adding opening which is used for adding water into the reaction container; a residue outlet which is communicated with the sample space, is used for discharging sample residues in the filter screen, and is connected with a residue discharge valve hung on the reaction container; and a liquid outlet which is arranged at the bottom of the reaction container, is communicated with the filtrate space and is used for discharging the filtrate after the reaction.

Description

technical field [0001] The invention relates to an on-line detection device for lime burning degree. Background technique [0002] Lime is an air-hardening inorganic gelling material with calcium oxide as the main component. It is made of raw materials with high calcium carbonate content such as limestone, dolomite, and shells, and is calcined at 900 to 1100 degrees Celsius. Because of its wide distribution of raw materials, simple production process and low cost, it is widely used in civil engineering. [0003] Lime raw materials are fired in the rotary kiln, filtered through the Kunming plate, cooled by the cooling system, and then discharged from the discharge port. During the raw burning process, in order to ensure the stable weight of the obtained quicklime, it is necessary to take samples several times to detect the degree of raw burning. The traditional detection method is to manually weigh the obtained sample and record it as G1, then place it in a container with a...
