Description

Technical Field

[0001] This invention relates to the field of expanded clay aerated concrete blocks, and particularly to a method for adjusting the concentration of cutting slurry for expanded clay aerated concrete blocks. Background Technology

[0002] The production of expanded clay aerated concrete blocks includes major processes such as pouring, curing, and cutting. When cutting expanded clay aerated concrete, water is needed for cooling and rinsing. During this process, mud containing cutting shavings is generated. In order to save resources, a set of processing technology is used to recycle and reuse the mud.

[0003] The existing process involves collecting the cutting slurry in a collection tank, then letting it settle in a gravity settling tank. The upper clear water is then recycled through a circulation tank for use in cutting ceramsite aerated concrete. The lower slurry is then reused for ceramsite aerated concrete pouring. Excess slurry is processed separately after passing through a plate and frame filter press, and the filtered water is recycled. In this process, when cutting and pouring are carried out simultaneously, the slurry prepared by this process has a poor solids content, making it difficult to control the slurry concentration to reach 20%. This limits the reuse of the cutting slurry in the pouring process. Summary of the Invention

[0050] The connecting mechanism includes four connecting rods 14 and a connecting plate 15;

The two second guide sliders 1606 are slidably inserted into two second guide grooves respectively, and the other end of the second insert rod 1605 is slidably inserted into one of the second positioning holes.

[0056] By utilizing the connection control of the first connector and the second connector, combined with the structure of the stirring assembly, the stirring mechanism can be adjusted in two ways, making the stirring structure more convenient and flexible to adjust.

[0057] Working principle of this invention: (Refer to...) Figure 3 - Figure 9 When using the stirring assembly;

[0058] First, adjust the stirring mechanism according to the stirring depth and stirring position; there are two ways to adjust it.

[0059] The first method involves pressing the two first insert rods 1302 towards the rotating sleeve 12. Under pressure, the two first insert rods 1302 slide within the two first receiving grooves, simultaneously causing the connected first guide slider 1303 to slide synchronously within its corresponding first guide groove. During the sliding process, the first guide slider 1303 compresses the first support spring 1304 within the first guide groove, causing it to gradually contract. Continuing to press the two first insert rods 1302 until they are fully embedded in the through first positioning hole 1201, allows them to slide at the bottom of the rotating sleeve 12. When the connecting rod 13 slides, the vertical distance between the two hinge seats located at the connecting support plate 1301 and the two hinge seats located at the rotating sleeve 12 changes. At this time, the four connecting rods 14 will rotate to maintain this distance change. Through the rotation of the connecting rods 14, the angle of the connecting rods 14 connected to the same connecting plate 15 changes. Therefore, when the connecting rod 13 is close to the rotating sleeve 12, the angle decreases and the horizontal distance between the connecting plate 15 and the rotating sleeve 12 increases. When the connecting rod 13 is far away from the rotating sleeve 12, the angle decreases and the horizontal distance between the connecting plate 15 and the rotating sleeve 12 decreases.

[0060] The second method involves pressing the second insert rod 1605 at the same sliding connecting block 16 towards the connecting plate 15. After being subjected to force, the second insert rod 1605 slides synchronously in the second receiving groove, simultaneously driving the connected second guide slider 1606 to slide synchronously in the corresponding second guide groove. During the sliding process of the second guide slider 1606, it will compress the second top support spring 1607 in the second guide groove, causing the second top support spring 1607 to gradually contract after being subjected to force. After pressing the second insert rod 1605 into the second positioning hole, the vertical position of the sliding connecting block 16 can be slidably changed. In this way, by changing the vertical position of the sliding connecting block 16, the angle of the connecting rod 14 changes, and the position of the stirring blade 1604 can be changed at the same time.

[0061] After the stirring mechanism is adjusted, the device is set up in the position to be used using the support plate 11. Then, the drive motor 10 is started. The drive motor 10 drives the connected rotating sleeve 12 to rotate through the output end. After the rotating sleeve 12 rotates, it drives the connecting rod 13 and the stirring mechanism to rotate. In this way, the stirring operation is performed by rotating the stirring blade 1604.

[0062] Example 3; For a project producing 150,000 cubic meters of expanded clay aerated concrete blocks annually, the cutting circulating water treatment process is as follows: the mud water containing cutting shavings is collected in wastewater collection tank 2 (50m³). 3 The material is collected and then processed through a plate and frame filter press 3 (200m). 2 The filtered water is then passed through a circulating water tank 1 (200m³). 3 The collected water can be reused for cutting aerated concrete with expanded clay aggregate. The filtered filter cake is added to a pre-filled mixing tank 4 (18m³) for batching. 3 When the solids content of the slurry reaches the concentration required for the production and casting of expanded clay aerated concrete blocks (20-30%), it is temporarily stored in a slurry transfer tank 5 (36m) equipped with a mixing unit. 3 The stored mud can be reused for pouring aerated concrete, thus achieving the recycling of mud water.

[0063] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
