Description

Technical Field

[0001] This application relates to the field of mortar processing technology, and more specifically, to a dry-mixed mortar drying device. Background Technology

[0002] Dry-mixed mortar, also known as dry powder mortar, refers to a granular or powdery material made by physically mixing aggregates, inorganic cementitious materials, and additives in a certain proportion after drying and screening. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water. It is widely used in construction and decoration projects, and drying is a very important process in the processing of dry-mixed mortar.

[0003] Chinese Patent (Publication No. CN220852924U) discloses a dry-mixed mortar drying device, including a processing box, a tank installed inside the processing box, a heat source injection mechanism fixed on the outer wall of the processing box, and a drying and dispersing mechanism inside the tank. The drying and dispersing mechanism includes a servo motor, the power output end of which passes through the end face of the processing box and is connected to a conveyor shaft, on which dispersing spiral discs are distributed. The dispersing spiral discs of this invention are relatively large, capable of carrying a large amount of dry-mixed mortar raw materials on their surface. The dispersing spiral discs prevent the added dry-mixed mortar raw materials from falling directly to the bottom of the tank, thus avoiding the problem of dry-mixed mortar raw material accumulation. Through the rotation and conveying of the dispersing spiral discs, the dry-mixed mortar raw materials can be more evenly dispersed in various positions within the tank, thereby improving the drying effect.

[0004] Regarding the aforementioned technologies, the inventors believe that a single-location heat source inlet means that the material can only be dried to a certain extent when passing through that location, resulting in incomplete drying. When the material is in other locations, the drying effect is very limited, leading to low drying efficiency and affecting the quality of the finished product to some extent. Utility Model Content

[0005] To address the aforementioned problems, this application provides a dry-mixed mortar drying device.

[0006] This application provides a technical solution using the following approach:

[0007] A dry-mixed mortar drying device includes a drying cylinder and a cover on the drying cylinder. A drive motor is installed in the middle of the upper surface of the cover. The output end of the drive motor passes through the cover and is connected to a material tower. The material tower includes a drive rod and a first material tray, a second material tray, and a third material tray fixedly arranged from top to bottom on the drive rod. A first air inlet, a second air inlet, and a third air inlet are respectively opened on one side wall of the drying cylinder, corresponding to the positions of the first material tray, the second material tray, and the third material tray. The first air inlet, the second air inlet, and the third air inlet are all connected to an external hot air blower through air supply pipes. A material inlet is also opened on the cover.

[0008] Through the above technical solution, the corresponding arrangement of multiple material trays and multiple air inlets enables the material to be effectively dried multiple times after entering the drying cylinder, which greatly improves the drying effect and efficiency of the material.

[0009] Furthermore, a feed pipe is connected below the inlet, and the lower end of the feed pipe extends to the top of the first material tray.

[0010] The above technical solution enables the material to smoothly pass through the feed pipe and fall onto the first material tray after entering from the feed port.

[0011] Furthermore, the surfaces of the first, second, and third material trays are all arranged in an inwardly concave arc shape, the diameters of the first, second, and third material trays increase sequentially, and the slopes of the surfaces of the first, second, and third material trays decrease sequentially.

[0012] Through the above technical solution, the material falls sequentially onto the first, second, and third trays after entering, achieving multiple and effective drying processes from multiple angles.

[0013] Furthermore, a discharge port is provided at the bottom of the drying cylinder, and a valve is installed on the discharge port.

[0014] With the above technical solution, after the material is dried and processed, the discharge is controlled by a valve.

[0015] Furthermore, a base is fixedly installed at the bottom of the drying drum.

[0016] Through the above technical solution, the addition of the base maintains the stability of the equipment during the processing and ensures the smooth completion of the processing.

[0017] Furthermore, an exhaust valve is also provided on the cylinder cover.

[0018] Through the above technical solution, the water vapor generated during the drying process can be discharged from the exhaust valve, maintaining the dryness inside the drying drum and further improving the drying effect.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] By setting up a material tower, with the combined use of multiple trays and air inlets, and the effect of centrifugal force during rotation, the wet material falls sequentially onto the first, second, and third trays after entering the drying cylinder. The material can be dried effectively in multiple directions. This graded drying avoids the incomplete drying caused by a single heat source, greatly improving the drying effect, increasing drying efficiency, and ensuring the quality of the finished product.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a dry-mixed mortar drying device. Please refer to [link / reference]. Figure 1-3 The system includes a drying cylinder 1 and a cylinder cover 2 covering the drying cylinder 1. A drive motor 3 is installed in the middle of the upper surface of the cylinder cover 2. The output end of the drive motor 3 movably passes through the cylinder cover 2 and is connected to a material tower 4. The material tower 4 includes a drive rod 401 and a first material tray 402, a second material tray 403, and a third material tray 404 fixedly arranged from top to bottom on the drive rod 401. A first air inlet 5, a second air inlet 6, and a third air inlet 7 are respectively opened on one side wall of the drying cylinder 1, corresponding to the positions of the first material tray 402, the second material tray 403, and the third material tray 404. The first air inlet 5, the second air inlet 6, and the third air inlet 7 are all connected to an external hot air blower 8 through air supply pipes. The cylinder cover 2... The equipment is also equipped with a feed inlet 9. When the equipment is in use, the drive motor 3 drives the material tower 4 to rotate. The wet material to be dried enters the drying cylinder 1 through the feed inlet 9 and falls onto the first material tray 402. Since the wet material has a certain degree of adhesion, it adheres to the surface of the first material tray 402 during rotation and is dried by hot air from the first air inlet 5. After drying to a certain extent, the adhesion of the material decreases. Under the action of centrifugal force, the material slides down and adheres to the second material tray 403, and is then dried by hot air from the second air inlet 6. After drying to a certain extent, the material slides down again under the action of centrifugal force and adheres to the third material tray 404, and is dried by hot air blown out from the third air inlet 7.

[0031] Figure 2 In the middle, a feed pipe 901 is connected below the feed inlet 9. The lower end of the feed pipe 901 extends to the top of the first material tray 402. After the material enters from the feed inlet 9, it passes smoothly through the feed pipe 901 and falls onto the first material tray 402.

[0032] Figure 3In this process, the surfaces of the first tray 402, the second tray 403, and the third tray 404 are all concave arc surfaces. This design ensures that the material can adhere to the trays and, after drying to a certain extent, slides down under the influence of wind and centrifugal force. The diameter and curvature of the first tray 402, the second tray 403, and the third tray 404 increase sequentially, ensuring that the material falls sequentially. Furthermore, the slope of the surfaces of the first tray 402, the second tray 403, and the third tray 404 decreases sequentially. The slope is designed to ensure that the wet material becomes increasingly dry after being dried sequentially, with decreasing moisture content and lower adhesion. The increasingly gentle slope ensures that the material can remain on the trays for a certain period of time, thus guaranteeing the drying effect.

[0033] Figure 2 In the middle, the lower part of the drying cylinder 1 is provided with a discharge port 10, and a valve 1001 is provided on the discharge port 10. After the material drying process is completed, the finished material is discharged from the discharge port 10 by the valve 1001.

[0034] Figure 1 In the middle, a base 11 is fixedly installed at the lower part of the drying cylinder 1. The base 11 can ensure the stability of the whole equipment during operation and ensure the smooth progress of processing.

[0035] Figure 2 In the middle, the cylinder cover 2 is also equipped with an exhaust valve 12, which can promptly remove water vapor during the material drying process, thereby ensuring the dryness inside the drying cylinder 1 and further improving the drying efficiency.

[0036] The implementation principle of the dry-mixed mortar drying equipment in this application embodiment is as follows: by setting up a material tower 4, with the combined use of multiple material trays and multiple air inlets, and the effect of centrifugal force during rotation, the wet material falls sequentially onto the first material tray 402, the second material tray 403 and the third material tray 404 after entering the drying cylinder. The material can be dried effectively in multiple directions. The graded drying avoids the incomplete drying of the material caused by a single heat source, greatly improves the drying effect of the material, increases the drying efficiency, and ensures the quality of the finished product.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
