Mortar is mainly composed of sand, cement, lime paste, clay and other cementing materials in a certain proportion, and water.

[0003] In order to improve the overall quality of mixed mortar, efficient dehumidification treatment of sand is particularly important. However, there are some deficiencies in the prior art, for example, a kind of mortar material production device with waterproof and anticorrosive function introduced in the Chinese utility model patent document with announcement number CN 216655317 U, although it tries to dehumidify sand in the screening process by hot air generated by drying fan, but the actual effect is not satisfactory. Specifically, the device dehumidifies in the relatively closed shell, which leads to the evaporation of water vapor in the shell, and then condenses into water droplets, which not only weakens the dehumidification effect, but also may cause subsequent problems.

[0004] In addition, because dehumidification and screening are processed at the same time, the moisture in the sand that has been bonded into blocks may be difficult to evaporate quickly, which affects the screening effect. More seriously, part of the sand may not be completely dehumidified before being screened out, which further reduces the efficiency and effect of dehumidification.

[0005] Therefore, it is necessary to invent a kind of mortar material production device with waterproof and anticorrosive effect. INVENTION CONTENTS

[0024] As shown in the accompanying Figure 1 to the accompanying Figure 4 :

[0025] The utility model provides a mortar material production device with waterproof and anticorrosive effect, including screening cylinder 1, discharge manhole 2, support frame 3, drive part 4, conveying dryer 5 and humidity exhaust fan 6, screening cylinder 1 is installed with discharge manhole 2, screening cylinder 1 is rotatably connected with two support frame 3 respectively, and the output of one drive part 4 is fixed with screening cylinder 1, screening cylinder 1 is rotatably connected with conveying dryer 5, and humidity exhaust fan 6 is fixedly installed above conveying dryer 5.

[0026] Further, screening cylinder 1 includes screening cylinder 11, sieve plate 12, end cover 13 and feed inlet 14, a plurality of sieve plates 12 are fixedly installed in screening cylinder 11. These sieve plates 12 are distributed in helical line path, which ensures that sand is fully screened in the cylinder. End covers 13 are fixedly installed at both ends of screening cylinder 11, and the two end covers 13 are rotatably connected with support frames 3, so that screening cylinder 11 can rotate stably. Discharge manhole 2 is arranged on the end cover 13 close to drive part 4, which facilitates maintenance and cleaning by the operator. The end cover 13 away from drive part 4 is provided with feed inlet 14, which is rotatably connected with the discharge pipe opening 52 of conveying dryer 5, ensuring that sand can smoothly enter screening cylinder 1 from conveying dryer 5.

[0027] Further, the feed inlet 14 of the screening drum 1 is ingeniously connected with the discharge pipe 52 of the conveying dryer 5, which design makes the sand dry during the conveying process, reducing the moisture content when entering the screening drum 1. At the same time, since the feed inlet 14 is located on the end cover 13 away from the driving part 4, and is arranged adjacent to the conveying dryer 5, this layout not only optimizes the space utilization, but also ensures the continuity of sand conveying.

[0028] Further, the screening drum 11 is located directly above the material guide cover 7, the upper opening of the material guide cover 7 is rectangular, the lower opening is circular, and the overall structure presents a conical geometric body, and the lower part of the material guide cover 7 is provided with a belt conveying device. This design allows the sand to freely fall through the material guide cover 7 onto the conveying device below after screening, ensuring the efficiency of screening and avoiding the scattering and waste of sand.

[0029] Further, the conveying dryer 5 includes a feeder shell 51, a discharge port 53, a fixed seat 54, a feeding screw 55, a screw motor 56, and a heating inner liner 57. The upper side and the lower side of the feeder shell 51 are respectively provided with a discharge pipe 52 and a discharge port 53. The feeding screw 55 is rotatably installed inside the feeder shell 51 and is rotatably connected with the fixed seat 54 fixedly installed inside the upper part of the feeder shell 51. The output end of the screw motor 56 fixedly installed inside the lower part of the feeder shell 51 is fixedly connected with the lower end of the feeding screw 55. The heating inner liner 57 is fixedly installed inside the feeder shell 51 and is located outside the feeding screw 55. The feeding screw 55 rotates under the drive of the screw motor 56 to convey the sand from the feeder shell 51 to the screening drum 1 through the discharge pipe 52. At the same time, the heating inner liner 57 heats and dries the sand to remove excess moisture. The top of the feeder shell 51 is also provided with a plurality of moisture exhaust holes, which cooperate with the externally fixed moisture exhaust fan 6 to quickly exhaust the moisture inside the feeder shell 51, ensuring the drying effect.

[0030] Further, the moisture exhaust fan 6 is an indispensable part of the conveying dryer 5. It is fixedly installed on the outside of the feeder shell 51, and by extracting the moisture inside the feeder shell 51, it ensures the dryness of the sand during the conveying and drying process. This design not only improves the drying efficiency, but also avoids the retention and accumulation of moisture inside the device, prolonging the service life of the device.

[0031] The working principle is as follows: first, the sand with high water content is poured into the feeder shell 51 through the discharge port 53. Start the screw motor 56, and the output end of the screw motor 56 drives the feeding screw 55 to rotate inside the feeder shell 51. The rotational movement of the feeding screw 55 lifts the sand upward from the bottom of the feeder shell 51 and pushes it forward along the inner wall of the feeder shell 51, until the sand is conveyed into the screening drum 1 through the discharge pipe 52.

[0032] In the process of sand being transported, the heating inner liner 57 heats and dries the sand inside the feeder shell 51. The heat generated by the heating inner liner 57 causes the excess moisture in the sand to evaporate rapidly, thereby achieving the purpose of removing moisture. At the same time, the moisture exhaust hole opened at the top of the feeder shell 51 and the externally fixed moisture exhaust fan 6 work together to quickly exhaust the moisture inside the feeder shell 51, ensuring the dryness of the sand during the transportation and drying process.

[0033] Then, the sand that has undergone drying treatment enters the screening drum 1. The screening drum 1 rotates smoothly under the drive of the drive part 4, and the inside of the throwing screen plate 12 is distributed in a spiral line path to fully screen the sand. The sand falls through the screening holes of the screening drum 11 into the material guide cover 7 below.

[0034] The upper opening of the material guide cover 7 is rectangular, the lower opening is circular, and the whole presents a conical geometric structure, so that the sand can smoothly fall through the material guide cover 7 onto the belt conveyor below. The belt conveyor transports the screened sand to the subsequent mortar material production process.

[0035] During the entire working process, the operator can maintain and clean the inside of the screening drum 1 through the discharge manhole 2, ensuring the normal operation of the device. At the same time, since the sand has been dried during transportation, the moisture content when entering the screening drum 1 is reduced, improving the screening efficiency and screening quality.

[0036] The technical scheme disclosed in the utility model, or the technical scheme designed by the person skilled in the art inspired by the technical scheme of the utility model, which achieves the above technical effects, falls within the protection scope of the utility model.
