Description

Technical Field

[0001] This utility model relates to the field of dryers, and in particular to a dryer for producing cement grinding aids. Background Technology

[0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It is mainly made by mixing cement grinding aid slurry and diluent in a certain proportion according to the properties of the cement used, so as to increase the hourly output of cement, the strength of cement at different ages, and improve its fluidity. In order to ensure the processing quality of cement grinding aid slurry, it needs to be dried in a dryer during the production process of cement grinding aid.

[0003] A search revealed a Chinese patent publication number CN222598298U, which discloses a uniform drying device for cement grinding aids. This patent includes a tank with an installation cavity inside. A cylinder is rotatably connected within the installation cavity, and a drying chamber is located within the cylinder. A rotating drum is rotatably connected within the drying chamber. The rotating drum has spiral blades on its outer circumference for conveying grinding aid powder. Multiple lifting blades are located on the inner wall of the cylinder, spaced apart radially and axially. A first connecting portion extends downwards to the outside of the installation cavity at the bottom of the cylinder. This device can disperse the cement grinding aid powder during the conveying process, facilitating more thorough and uniform drying. However, current desiccants used in cement grinding aid production often result in caking of the wet powder within the dryer during the drying process. Furthermore, the drying effect is difficult to guarantee for portions of the cement grinding aid far from the heat source, requiring longer drying times, which affects production efficiency and overall drying effectiveness.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6As shown, a dryer for producing cement grinding aids includes a mounting platform 101. A collection box 103 is bolted to the bottom of the mounting platform 101. A feeding mechanism is provided on the mounting platform 101, including a fixed box 201 with an inner cavity 203. A hopper 202 is bolted to the top of the fixed box 201. A rotating mechanism is provided on the fixed box 201, including a motor 301 bolted to the mounting platform 101. The output end of the motor 301 is connected to a drive shaft 302 via a coupling. A rotating shaft 303 is bolted to the end of the drive shaft 302 away from the motor 301. Spiral blades 304 are bolted to the rotating shaft 303. Several connecting shafts 305 are welded onto 304 and arranged in a ring. A fixed cylinder 307 is bolted to one side of the fixed box 201. Several support blocks 102 are fixedly connected to the top of the mounting platform 101 and are fixedly connected to the bottom of the fixed cylinder 307. A heating wire 308 is bolted inside the fixed cylinder 307 and is connected to an external power source via an electric wire. A spiral blade 304 is rotatably mounted inside the fixed cylinder 307. The rotation of the spiral blade 304 inside the fixed cylinder 307 can push the cement grinding aid to move inside the fixed cylinder 307 and can effectively prevent caking. A blower mechanism is fixedly mounted on the top of the mounting platform 101 and is located at the end of the fixed cylinder 307 away from the fixed box 201.

[0026] In this embodiment, the connecting shaft 305 passes through the spiral blade 304 along the axial direction of the rotating shaft 303. A shovel plate 306 is bolted to the connecting shaft 305. The shovel plate 306 is arc-shaped, and the arc of the shovel plate 306 faces the rotation direction of the rotating shaft 303. The arrangement of the connecting shaft 305 and the shovel plate 306 enables the cement grinding aid to be reciprocated during its movement in the fixed cylinder 307, further preventing caking.

[0027] In this embodiment, the blower mechanism includes a mounting box 401, which is bolted to a mounting platform 101. A hot air blower 402 is bolted to the mounting platform 101, and a blower pipe 403 is bolted to the air outlet of the hot air blower 402. The blower pipe 403 is connected to the mounting box 401. The hot air blown out by the hot air blower 402 and the heating wire 308 work together to dry the cement grinding aid in the fixed cylinder 307. The spiral air duct formed in the spiral blade 304 can achieve a more comprehensive and thorough drying effect on the cement grinding aid.

[0028] In this embodiment, several partition plates 404 are bolted inside the installation box 401. An inclined surface 405 is provided on the inner wall of the installation box 401 away from the fixed cylinder 307. The bottom of the installation box 401 is connected to the collection box 103. The inclined surface 405 forms a material discharge channel inside the installation box 401, so that the dried cement grinding aid can fall smoothly into the collection box 103.

[0029] In this embodiment, the inner cavity 203 is spiral-shaped. This design prevents the cement grinding aid from accumulating in the inner cavity 203 due to the wind force of the hot air blower 402. The cement grinding aid can move stably towards the mounting box 401 as the spiral blades 304 rotate. The inner cavity 203 of the fixed box 201 and the hopper 202 are connected by bolts to a grid plate 204. The line formed by the grid plate 204 coincides with the top of the inner cavity 203. A portion of the cement grinding aid in the inner cavity 203 will be blown to a higher position. At this time, the grid plate 204 allows the cement grinding aid to continue rolling along the inner wall of the grid plate 204, preventing it from accumulating in the inner cavity 203. At the same time, it does not affect the cement grinding aid falling into the inner cavity 203 through the gaps between the grid plates 204.

[0030] Working Principle: When in use, the motor 301, heating wire 308, and hot air blower 402 are started, driving the drive shaft 302 and rotating shaft 303 to rotate. The cement grinding aid raw material to be dried is added through the hopper 202. The material falls through the gaps in the grid plate 204 into the spiral-shaped inner cavity 203 below. The spiral blades 304, bolted to the rotating shaft 303, rotate within the inner cavity 203. The spiral design of the inner cavity 203 prevents the material from accumulating disorderly under the influence of airflow, ensuring that the material is stably and continuously transported to the drying area. Subsequently, the cement grinding aid to be dried is pushed into the fixed cylinder 307 by the spiral blades 304. The hot air blower 402 blows hot air into the cylinder through the air pipe 403 and the partition plate 404. Inside the mounting box 401, the hot airflow is opposite to the material's movement direction and flows along the spiral channel formed between the spiral blades 304 and the fixed cylinder 307 to dry the cement grinding aid. As the cement grinding aid moves within the fixed cylinder 307, the rotation of the spiral blades 304 prevents caking on the inner wall of the fixed cylinder 307. The connection shaft 305 and the shovel plate 306 repeatedly shovel up the cement grinding aid, allowing the material particles at the bottom to be fully exposed to the hot air. Combined with the dual heating of the heating wire 308, this results in a better drying effect. The cement grinding aid that has completely passed through the fixed cylinder 307 finally enters the mounting box 401 and falls into the collection box 103 from the inclined surface 405, completing the drying process.

[0031] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power (or 380V industrial power), and the main controller can be a conventional known device such as a computer that provides control.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
