[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion. It is also called mortar or cement paste. Common types of mortar include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar.

[0003] In the mortar production process, raw materials need to be mixed in a certain proportion. Before mixing, in order to ensure the accuracy of the raw material proportion, the raw materials usually need to be dried to reduce the moisture content and improve the accuracy of the proportion. However, the existing drying equipment is not convenient for tumbling and stirring the raw materials when drying them. The raw materials are prone to clumping in the equipment, resulting in uneven drying, affecting the drying effect, and causing inconvenience to users.

[0004] Therefore, it is necessary to modify the process so that the raw materials are repeatedly turned over during drying to ensure even heating, prevent clumping, improve drying effect and efficiency, and make it more convenient for users. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a rapid drying device for mortar production. This device features the advantage of repeatedly turning the raw materials during drying, ensuring uniform heating, preventing clumping, improving drying effect and efficiency, and facilitating user operation. It solves the problem that existing drying devices are inconvenient for turning and stirring raw materials during drying, leading to clumping within the device, uneven drying, and affecting the drying effect, thus causing inconvenience to users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid drying device for mortar production, comprising a drying box, a material box fixedly connected inside the drying box, a conveying cylinder arranged inside the material box, the bottom of the conveying cylinder being fixedly connected to the bottom of the inner wall of the drying box, and inlets being provided around the bottom of the conveying cylinder; a heating wire arranged inside the drying box, the inner side of the heating wire being in contact with the surface of the material box; a drive motor fixedly connected to the bottom of the drying box via a bracket, a spiral conveying rod arranged at the output end of the drive motor, the top end of the spiral conveying rod penetrating into the interior of the drying box and extending above the conveying cylinder; an exhaust duct arranged at the top of the material box, an exhaust fan arranged inside the exhaust duct, and the surface of the exhaust duct being fixedly connected to the inner wall of the material box via support rods; and a discharge valve pipe connected to the right side of the bottom of the drying box.

[0007] As a preferred embodiment of this invention, the inner wall of the drying oven is fixedly connected with a heat insulation layer located outside the heating wire, the surface of the material box is fixedly connected with a heat absorption layer, and the material box is made of a heat-conducting metal material.

[0008] As a preferred embodiment of this utility model, a sealed bearing is fixedly connected to the surface of the top end of the spiral conveyor rod, and a stabilizing rod is fixedly connected to both the left and right sides of the sealed bearing. The outer end of the stabilizing rod is fixedly connected to the inner wall of the material box.

[0009] As a preferred embodiment of this invention, a water injection valve pipe is connected to the top of the left side of the drying box, and a drain valve pipe is connected to the bottom of the left side of the drying box.

[0010] As a preferred embodiment of this utility model, the top and bottom of the exhaust duct are both movably connected to a protective frame by bolts, and a protective net is fixedly connected inside the protective frame.

[0011] As a preferred embodiment of this utility model, hollow support legs are fixedly connected to all four sides of the bottom of the drying box, and an electric telescopic rod is fixedly connected inside the hollow support legs. A universal wheel is fixedly connected to the output end of the electric telescopic rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a material box and a conveying cylinder inside the drying oven, with a feeding port at the bottom, and cooperating with a spiral conveying rod driven by a drive motor, allows the mortar raw materials to be continuously conveyed and tumbled inside the conveying cylinder. This ensures that the raw materials fully contact the heat generated by the heating wire, preventing the raw materials from clumping and making the heating more uniform, thereby improving drying efficiency and effect. For example, the spiral conveying rod conveys the raw materials from the bottom to the top. During this process, the raw materials are constantly turned over, increasing the contact area and time with hot air, which helps the moisture evaporate quickly. The exhaust duct with an exhaust fan can promptly remove the moisture generated during the drying process from the drying oven, further accelerating the drying speed and ensuring the drying quality. This achieves the effect of repeatedly turning the raw materials during drying, ensuring uniform heating, preventing the raw materials from clumping, improving the drying effect and efficiency, and making it convenient for users.

[0014] 2. This utility model reduces heat loss by setting up a heat insulation layer, allowing more heat to concentrate inside the drying chamber and improving energy efficiency. At the same time, the heat-absorbing layer on the surface of the material box can better absorb the heat from the heating wire and transfer the heat to the mortar raw materials inside through the heat-conducting metal material of the material box, thus accelerating the drying process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a rapid drying device for mortar production, including a drying box 1, a material box 2 fixedly connected inside the drying box 1, a conveying cylinder 3 inside the material box 2, the bottom of the conveying cylinder 3 fixedly connected to the bottom of the inner wall of the drying box 1, and a feeding port on all four sides of the bottom of the conveying cylinder 3. A heating wire 4 is installed inside the drying box 1, and the inner side of the heating wire 4 is in contact with the surface of the material box 2. A drive motor 5 is fixedly connected to the bottom of the drying box 1 by a bracket. A spiral conveying rod 6 is installed at the output end of the drive motor 5. The top of the spiral conveying rod 6 penetrates into the interior of the drying box 1 and extends above the conveying cylinder 3. An exhaust duct 7 is installed at the top of the material box 2, and an exhaust fan 8 is installed inside the exhaust duct 7. The surface of the exhaust duct 7 is fixedly connected to the inner wall of the material box 2 by a support rod. A discharge valve pipe 9 is connected to the right side of the bottom of the drying box 1.

[0022] refer to Figure 2 The inner wall of the drying oven 1 is fixedly connected with a heat insulation layer 10 located outside the heating wire 4, and the surface of the material box 2 is fixedly connected with a heat absorption layer 11. The material box 2 is made of heat-conducting metal.

[0023] As a technical optimization of this utility model, by setting the heat insulation layer 10, heat loss can be reduced, and more heat can be concentrated inside the drying box 1, thereby improving energy utilization efficiency. At the same time, the heat-absorbing layer 11 on the surface of the material box 2 can better absorb the heat of the heating wire 4, and transfer the heat to the mortar raw material inside through the heat-conducting metal material box 2, thereby accelerating the drying process.

[0024] refer to Figure 2 A sealed bearing 12 is fixedly connected to the top surface of the spiral conveyor rod 6. A stabilizing rod 13 is fixedly connected to both the left and right sides of the sealed bearing 12. The outer end of the stabilizing rod 13 is fixedly connected to the inner wall of the material box 2.

[0025] As a technical optimization of this utility model, by setting a sealed bearing 12 and a stabilizing rod 13 to be fixedly connected to the inner wall of the material box 2, the stability of the spiral conveyor rod 6 during rotation can be enhanced, ensuring its normal operation, reducing vibration and shaking, thereby making the conveying of raw materials more stable and smooth, and improving the reliability of the drying process.

[0026] refer to Figure 2 A water injection valve pipe 14 is connected to the top left side of the drying box 1, and a drain valve pipe 15 is connected to the bottom left side of the drying box 1.

[0027] As a technical optimization of this utility model, by setting up the water injection valve pipe 14 and the drain valve pipe 15 for use together, water can be injected into the interlayer between the drying box 1 and the material box 2 through the water injection valve pipe 14 during drying. The heat generated by the heating wire 4 is conducted through the water, so that the material box 2 is heated more evenly, further improving the drying effect. After drying is completed, the water can be drained through the drain valve pipe 15.

[0028] refer to Figure 2 The top and bottom of the exhaust duct 7 are movably connected to the protective frame 16 by bolts, and the protective frame 16 is fixedly connected to the inside of the protective net.

[0029] As a technical optimization of this utility model, by setting the protective frame 16 and the internal protective net, it is possible to prevent debris from entering the exhaust duct 7 and damaging the exhaust fan 8. At the same time, it can also prevent operators from accidentally touching the exhaust fan 8 and causing danger, extend the service life of the exhaust fan 8, and ensure safe use.

An electric telescopic rod 18 is fixedly connected inside the hollow support legs 17. A caster wheel 19 is fixedly connected to the output end of the electric telescopic rod 18.

[0031] As a technical optimization of this utility model, by setting up hollow support legs 17, electric telescopic rods 18 and casters 19 for coordinated use, when the device needs to be moved, the electric telescopic rods 18 extend to make the casters 19 touch the ground, making it convenient to move the device; when it needs to be fixed, the electric telescopic rods 18 retract to make the casters 19 retract, allowing the hollow support legs 17 to touch the ground, ensuring the stability of the device and adapting to different working scenarios.

[0032] The working principle and usage process of this utility model are as follows: In use, the raw materials are added to the device through the opening at the top of the material bin 2. Then, the heating wire 4 is activated to begin heating. Since the material bin 2 is made of thermally conductive metal and has a heat-absorbing layer 11 on its surface, it can efficiently absorb the heat generated by the heating wire 4 and transfer the heat to the inside of the material bin 2, thereby heating and drying the mortar raw materials inside the material bin 2. Simultaneously, the heat insulation layer 10 on the inner wall of the drying chamber 1 reduces heat loss, ensuring that as much heat as possible is used to dry the raw materials, improving energy efficiency. At the same time, the drive motor 5 is activated, and its output drives... The spiral conveyor rod 6 rotates, and the mortar raw material enters the conveying cylinder 3 from the feed inlets around the bottom. Under the action of the spiral conveyor rod 6, the raw material is conveyed upward. During the conveying process, the raw material tumbles continuously, increasing the contact area and time with hot air, making the raw material heat more evenly, avoiding the raw material from clumping, and further improving the drying effect and efficiency. During the drying process, the exhaust fan 8 operates to promptly discharge the moisture generated in the material box 2 into the drying chamber 1, accelerating the drying speed and ensuring the drying quality. After drying is completed, the discharge valve pipe 9 is opened to discharge the raw material.
