Description

Technical Field

[0001] The utility model relates to the field of concrete mortar admixture raw material processing, in particular to concrete mortar admixture raw material processing equipment. Background Art

[0002] Concrete mortar admixtures are a type of substance used to improve and adjust the properties of concrete and mortar. They can be added during the mixing of concrete or mortar. Concrete mortar admixtures can be classified according to their main functions, namely, admixtures that can adjust rheological properties, setting time, hardening properties, durability, etc. Among them, the admixture that can adjust the setting time of concrete is an accelerator, which is a chemical additive made from raw materials such as quicklime, sodium carbonate, sodium aluminate, calcium aluminate, bauxite, and soda ash. In the preparation process, the raw materials must first be crushed using a jaw crusher and a hammer crusher to reduce the particle size of the raw materials, and then the crushed particles must be crushed using a ball mill. The crushed raw materials are ground into powder, and then screened and graded to ensure that the powdered materials reach the required fineness requirements. The ground bauxite, soda ash and quicklime are then sent to a rotary kiln for calcination. By controlling the temperature and time, the raw materials undergo chemical changes and are fired into clinker. The fired block clinker is then cooled. After cooling, the clinker and other additives are ground together to form a masterbatch of an accelerator. The masterbatch is then compounded with other necessary ingredients to achieve the desired performance. In the process of cooling the block clinker, the block clinker needs to be placed in a single-drum cooler and cooled by the rolling and natural wind of the single-drum cooler.

[0003] In the above preparation process, during the cooling process, since the existing cooling of clinker is through the rolling of a single-drum cooler and then cooling by natural wind, it takes a long time to cool the block clinker, resulting in a longer cooling time for the clinker and reducing the preparation efficiency of the accelerator. Therefore, the present application provides a concrete mortar admixture raw material processing equipment to meet the needs. Utility Model Content

[0030] As Figure 1 shown, an embodiment of the present utility model provides a device for processing raw materials of a concrete mortar admixture, including a base 1. A cooling cylinder 2 is rotatably connected to the top of the base 1. An axial flow fan 8 is arranged on the side of the cooling cylinder 2. A plurality of air ducts 3 are fixedly connected to the inner wall of the cooling cylinder 2. A plurality of ventilation holes 11 are formed on the side of the air duct 3 facing the axis of the cooling cylinder 2. One end of the air duct 3 extends to the outside of the cooling cylinder 2. A positioning ring 7 is fixedly connected to the side of the axial flow fan 8 close to the cooling cylinder 2. An annular groove 12 is formed on the side of the positioning ring 7 close to the cooling cylinder 2. A circular ring 4 is rotatably connected to the inside of the annular groove 12. A disc 6 is fixedly connected to the side of the circular ring 4 close to the cooling cylinder 2. The disc 6 is fixedly sleeved on one end of the air duct 3 close to the axial flow fan 8. When it is necessary to cool the massive clinker, by putting the massive clinker into the cooling cylinder 2, starting the axial flow fan 8 and the cooling cylinder 2, blowing the air blown out by the axial flow fan 8 into the cooling cylinder 2 through the air duct 3, and then starting the cooling cylinder 2 to rotate, the massive clinker in the cooling cylinder 2 can be better cooled, realizing the forced cooling of the massive clinker, greatly reducing the cooling time, improving the cooling efficiency, and thus being beneficial to improving the preparation efficiency of the accelerating agent.

[0031] As Figure 3 shown, a sealing ring is provided on the circumferential surface of the circular ring 4, and the sealing ring is used for sealing between the circular ring 4 and the annular groove 12; it can better improve the sealing performance between the circular ring 4 and the annular groove 12.

[0032] As Figure 2 shown, baffle rings 5 are fixedly connected to both ends of the cooling cylinder 2, and the baffle rings 5 are fixedly sleeved at the end positions of the air duct 3; when the cooling cylinder 2 rotates to drive the bulk clinker in the cylinder to roll, through the baffle rings 5 at both ends, it can better prevent the bulk clinker from spilling outside the cooling cylinder 2 during the rolling process, improve the residence time of the bulk clinker in the cylinder, and thus improve the cooling time of the bulk clinker.

[0033] As Figure 5 shown, inclined portions 9 are provided on both sides of the air duct 3, and the ventilation holes 11 are opened on the inclined portions 9 of the air duct 3; the inclined portions 9 guide the air blown out by the air duct 3, which is beneficial to guiding the air blown out by the air duct 3 to the bulk clinker in the cooling cylinder 2 and improving the cooling efficiency of the bulk clinker.

[0034] As Figure 5 shown, an arc portion 10 is provided on the side of the air duct 3 facing the axis of the cooling cylinder 2, and the arc portion 10 is used for connecting two inclined portions 9 on the same air duct 3; it can better guide the air blown out by the air duct 3 to the ventilation holes 11, so as to better cool the bulk clinker in the cooling cylinder 2 and is beneficial to improving the cooling efficiency of the bulk clinker.

[0035] As Figure 5 shown, the distance between the opposite sides of the inner wall of the inclined portion 9 gradually decreases in the direction away from the air duct 3; it can better increase the flow rate of the air blown out by the air duct 3, so as to better cool the bulk clinker in the cooling cylinder 2 and is beneficial to improving the cooling efficiency.

[0036] As Figure 2 shown, the central axis of the annular groove 12 coincides with the central axis of the positioning ring 7; it can better improve the stability of the circular ring 4 during rotation and prevent the circular ring 4 from shifting due to the offset during the opening of the annular groove 12.

[0037] As Figure 4 shown, a plurality of the air ducts 3 are annularly arrayed with the center of the cooling cylinder 2 as the array center; it can better cool the bulk clinker in the cooling cylinder 2 evenly and is beneficial to improving the cooling efficiency.

[0038] Working principle:

[0039] When it is necessary to cool the calcined massive clinker, the calcined massive clinker is put into the cooling cylinder 2. Then, the axial flow fan 8 and the cooling cylinder 2 are started. By the rotation of the cooling cylinder 2, the air duct 3 is driven to rotate. Then, the air duct 3 drives the baffle ring 5 and the disk 6 to rotate, so as to drive the ring 4 fixedly connected to the side of the disk 6 to rotate in the annular groove 12 formed on the side of the positioning ring 7, which can better tumble the clinker in the cooling cylinder 2. While rotating, since the positioning ring 7 is fixedly connected to the axial flow fan 8, the air blown out by the axial flow fan 8 passes through the positioning ring 7 and the disk 6 and is blown into the air duct 3. Then, the air duct 3 blows the air blown out by the axial flow fan 8 into the cooling cylinder 2 through the ventilation holes 11, which cooperates with the rotation of the cooling cylinder 2 to uniformly cool the massive clinker in the cooling cylinder 2, can better improve the cooling efficiency, shorten the cooling time, and thus improve the preparation efficiency of the quick-setting agent.
