Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to an automatic feeding cement raw material batching device. Background Technology

[0002] Cement production processes can generally be divided into: raw meal preparation, coal powder preparation, clinker calcination, cement grinding, and delivery. Among these, the quality of the cement raw meal before calcination in the kiln is crucial. Cement raw meal is made by mixing and grinding four raw materials: limestone, sandstone, iron tailings, and mudstone.

[0003] Existing cement raw material batching devices, such as the one disclosed in CN215197507U, have the advantages of greatly improving the efficiency of cement raw material batching and reducing the labor intensity of workers. However, it is inconvenient to carry out dust protection when the material in the silo is weighed and poured onto the conveyor, and when the material poured onto the conveyor is transported to the grinding mill. This makes it difficult to ensure the air safety of the working environment. Therefore, we propose an automatic feeding cement raw material batching device. Utility Model Content

[0027] The following describes, with reference to the accompanying drawings, some embodiments of an automatic cement raw material batching device provided by this utility model.

[0028] Example 1:

[0029] Combination Figure 1-7As shown, this utility model provides an automatic cement raw material batching device, comprising: a main body 100, a dustproof component 200, and a support component 300; the main body 100 includes multiple raw material bins 101, a conveyor 102 at the bottom of the raw material bins 101, a grinding mill 103 on one side of the bottom of the conveyor 102, a feeding pipe 104 fixedly connected to the bottom of the raw material bins 101, and solenoid valves 105 fixedly installed on the feeding pipes 104; the dustproof component 200 includes a dust cover 201 fixedly installed at the upper end of the conveyor 102, a rotating shaft 202 movably installed in the center of the dust cover 201, multiple fixed seats 203 arranged and fixedly installed on the rotating shaft 202, a weight scale 204 fixedly installed on each fixed seat 203, a receiving cylinder 205 fixedly installed on each weight scale 204, a scraper 206 fixedly installed on one side of the conveyor 102, and a scraper 206 on one side of the bottom of the conveyor 102. The feed inlet 207 and the feed cover 208 fixedly installed at the bottom of the feed inlet 207; the support assembly 300 includes a movable frame 301 movably installed on both sides of the outer end of the dust cover 201, and multiple sets of support plates 302 fixedly installed on the movable frame 301; the upper end of the grinding mill 103 is also provided with a feed inlet 209, and the bottom of the feed cover 208 is located in the feed inlet 209; a geared motor 210 is also fixedly installed on one side of the rotating shaft 202, and the geared motor 210... 10 is fixed to the outer end of the dust cover 201. The top of the dust cover 201 is also provided with multiple sets of insertion holes 211, and the feeding pipe 104 is located in the insertion holes 211. The top of the dust cover 201 is also fixedly installed with a double-headed cylinder 303, and both ends of the double-headed cylinder 303 are fixedly connected to the support plate 302. Both ends of the dust cover 201 are also provided with multiple sets of slots 304, and the support plate 302 is movably matched and installed in the slots 304.

[0030] Specifically, cement raw materials are made by mixing and grinding four raw materials: limestone, sandstone, iron tailings, and mudstone. The cement raw material batching device is a device for weighing and batching cement raw materials. The main body 100 of this device includes a dust cover 201 installed on the conveyor 102, a weighing scale 204 located at the bottom of the discharge pipe 104 within the dust cover 201, and a discharge cover 208 installed between the conveyor 102 and the feed inlet 209 of the grinding mill 103. These features provide dust protection during the automatic material feeding process in the raw material silo 101 and ensure dust protection throughout the entire process of material transport to the grinding mill 103, thereby ensuring a safe working environment and improving dust protection and safety during use. Simultaneously, the multiple support plates 302 at both ends, driven by the double-headed cylinder 303 on the dust cover 201, also support the weighing scale 204 at both ends during weighing within the dust cover 201, ensuring the stability of the weighing scale 204 during weighing. To ensure weighing accuracy, the rotating shaft 202 driven by the geared motor 210 inside the dust cover 201 is mainly used for rotating, flipping, and tilting the material after weighing on the weighing scale 204. The receiving cylinder 205 on the weighing scale 204 is mainly used for receiving the material in the discharge pipe 104. The scraper 206 fixedly installed on one side of the conveyor 102 is located on one side of the conveyor belt and can scrape off the material being transported by the conveyor belt to reduce residue and ensure the accuracy of the conveying process. Material falls into the discharge hood 208 through the discharge port 207. The feed port 209 set at the upper end of the grinding mill 103 is mainly used to connect with the discharge hood 208, thereby ensuring that the material on the conveyor 102 is transported to the grinding mill 103 without dust. The dust cover 201 opened at the top of the dust cover 201 is mainly used for the installation of the discharge pipe 104 at the bottom of the raw material silo 101. The slots 304 arranged at both ends of the dust cover 201 are mainly used for the installation and support of the support plate 302.

[0031] Working principle and usage process of this utility model:

[0032] Materials from multiple raw material bins 101 are fed to the weighing scale 204 via the bottom feed pipe 104. The weighing scale 204 weighs the material, and once the weight is reached, the feed pipe 104 is closed via the solenoid valve 105. After all materials have been weighed on the multiple weighing scales 204 inside the dust cover 201, the double-headed cylinder 303 at the top of the dust cover 201 and the conveyor 102 are activated. After the double-headed cylinder 303 is activated, it drives the movable frames 301 at both ends to move outward, thereby moving the weight supported at both ends of the bottom of the weighing scale 204. After the support plate 302 moves outward, the reduction motor 210 can be started to reduce the rotation of the rotating shaft 202 inside the dust cover 201, thereby flipping the multiple sets of weight scales 204 on the rotating shaft 202 to pour the weighed material onto the conveyor 102 and move along the conveyor 102. After being scraped off by the scraper 206, the material falls into the discharge port 207 and is conveyed to the grinding mill 103 along the discharge cover 208 at the bottom of the discharge port 207, so as to ensure the dust-free conveying of materials in the automatic feeding of the raw material silo 101.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
