The technical scheme of the invention is further explained by combining the attached figures 1-2 and the specific implementation mode.
A method for detecting the blank density distribution uniformity of a ceramic green brick comprises the following specific steps:
s1) taking a piece of ceramic adobe, dividing the ceramic adobe into N adobes with the same size, marking and recording the positions corresponding to the N adobes, and weighing and recording the weights M1, M2, M.
S2) applying a downforce to completely immerse the N compacts in mercury, respectively, and sequentially measuring and recording the corresponding downforce F1, F2,. and.fn of the N compacts;
s3) obtaining the density of the N briquettes by calculation, wherein the density of the nth briquette is calculated by the formula ρ N ═ ρMercuryG Mn/(Fn + Mn g), N1, 2, N, Mn being the weight of the nth compact, Fn being the downward force acting on the nth compact, ρMercuryMercury density, g is the gravity coefficient;
s4) distributing the density of the ceramic adobe according to the positions of the N adobes before division to generate a blank filling density distribution map of the ceramic adobe.
The ceramic tile blank particles prepared by the dry granulation powder-making process have the problems of difficult control of particle size composition, small particle compression ratio and particle mobility deviation, and after the ceramic tile blank is pressed by distributing the blank by a pressing machine, the blank has poor distribution uniformity in the transverse direction and the longitudinal direction of the ceramic tile blank, so that the ceramic tile blank is easy to deform and crack in the subsequent firing process, the batch qualification rate of the ceramic tile blank is low, and the waste is large and the loss is serious.
According to Archimedes' law, the buoyancy of a slug suspended in mercury is equal to the product of the volume of the slug and the density of the mercury, the buoyancy being equal to the sum of the downforce and the weight of the slug, i.e. Fn + Mn g ρMercuryG Vn, Vn is the volume of the nth compact, and the conversion formula of the volume of the compact with the weight Mn and the density ρ n is Vn-Mn/ρ n, so that the density of the nth compact can be calculated as ρ n- ρMercuryG Mn/(Fn + Mn g), wherein N is 1, 2,. and N, Mn is the weight of the nth compact, ρMercuryIs the density of mercury (equal to 13.6 g/cm)3) G is the gravity coefficient (equal to 9.8N/kg) and Fn is the downward force on the N-th billet.
The method for detecting the blank density distribution uniformity of the ceramic green bricks comprises the steps of detecting the density distribution uniformity of the blanks of the ceramic green bricks by a method for measuring buoyancy according to Archimedes' law, equally dividing one ceramic green brick into a plurality of blanks, respectively detecting and obtaining the buoyancy of each blank immersed in mercury, calculating the density of each blank according to the measured buoyancy and the weight of the blank, distributing the obtained density data of each blank according to the position of the blank before division to obtain the density distribution diagram of the ceramic green bricks, measuring the volume of the blank in the detection process, weighing the weight and the downward pressure of the blank, and being simple and convenient to operate, high in reliability and suitable for detecting the density distribution of the ceramic green bricks of various specifications.
Preferably, the ratio of the lengths of the two adjacent sides of the compact is 0.6 to 1.0.
If the difference in the lengths of the two adjacent sides of the divided block is too large, breakage is liable to occur in the test, and the longer side is too large for the distribution width of the block, the change of the distribution state involved is complicated and inconvenient to observe and analyze, and it is appropriate to set the length ratio of the two adjacent sides of the divided block to 0.6 to 1.0.
Further, the method also comprises the following steps:
s5), finding out the maximum value Max and the minimum value Min in the numerical values of the densities of the N blocks according to the density distribution diagram of the ceramic brick blank in the step S4);
s6) comparing the difference between the maximum Max and minimum Min with a preset threshold: if the difference value is not greater than the threshold value, the uniformity degree of the blank filling density of the ceramic green brick meets the requirement, and the detection is finished; if the difference value is larger than the threshold value, continuing to execute the following steps;
s7) selecting the briquettes with the density value smaller than the maximum value Max and the difference value exceeding the threshold value from the N briquettes, and analyzing and searching for the cloth defects of the briquettes;
s8) correspondingly adjusting the material distribution device parameters of the green pressing machine in the area according to the found material distribution defects;
s9), after the parameters of the distributing device are adjusted, the green pressing machine is restarted to press a plurality of ceramic adobes, and the specifications and the blanks of the ceramic adobes are the same as those of the ceramic adobes in the step S1);
s10) taking any one of the ceramic green bricks repressed in the step S9), and repeatedly performing the steps S1) to S9).
Before ceramic green bricks are produced in batches, the part of the green bricks with low density is found out by the method, the distribution defect of the part is analyzed, the parameters of a distribution device at the defective part can be analyzed and adjusted in a targeted manner, the quality of the ceramic green bricks produced in batches is improved, and the loss and waste of the firing process caused by uneven distribution are avoided. According to the density corresponding to the position mark with the consistent real object of the ceramic brick blank, the appearance defect of the part with abnormal density distribution can be visually contrasted and analyzed, the reason of uneven distribution of the ceramic brick blank is found by detecting the appearance defect of the part with abnormal density distribution filled by the blank of the ceramic brick blank, and the density distribution uniformity of the blank at the part can be improved by adjusting the press stroke, the retention time or the pressing point position of the mold core of the corresponding distribution of the defect part.
Preferably, the threshold value is less than or equal to 0.1g/cm3
Setting the difference value between the maximum value and the minimum value in the density of each part of the ceramic green brick to be less than or equal to 0.1g/cm3And the ceramic green brick after firing has good flatness and can meet the technical requirements of the highest standard of the existing industry.
Specifically, in step S7), the cloth defects include stacking, missing material, and uneven thickness.
When the dry powder material distribution is adopted, due to the poor particle flowability of the powder material, the uneven distribution easily occurs at the two ends of the die, some places are thick, some places are thin, even the thickness of the thick part is 20-30% higher than that of the thin part, and the accumulation phenomenon may occur at the edge or corner part.
Specifically, in step S8), the parameters of the material distribution device include a start-stop position of a material distribution stroke, a length of the material distribution stroke, a material distribution residence time, and a mold core lowering position.
If the cloth is piled up or the thickness is not uniform, the distance of the stroke of the cloth device or the stay time parameter needs to be adjusted quickly at the thick part of the cloth, for example, the pause time is adjusted to be reduced from the original 1.5 seconds to 1 second; for the thinner part of the cloth, the parameters of the cloth device are adjusted slowly, for example, the pause time is adjusted to be increased from the original 1.2 seconds to 1.5 seconds.
For example, when powder is accumulated at the corner, the forward displacement of the distributing device can be adjusted to a certain movement amount towards the running front end direction of the die, the stroke distance of the distributing device is increased by 5-10%, then blanking is started, and the distribution at the corner becomes uniform.
On the contrary, if a certain part has material shortage, the advancing displacement of the distributing device can be moved to the point position of the material shortage, and the stroke distance of the distributing device and the pressing position of the mold core are correspondingly adjusted, so that the part with the material shortage can be compacted while the material is increased.
