Abstract
Description
Technical Field
[0001] This utility model relates to the field of mortar processing technology, specifically to a dry powder mortar screening and drying device. Background Technology
[0002] The dry mortar screening and drying device is a special equipment used for screening and drying dry mortar. Its core function is to remove impurities, control particle size distribution and reduce moisture content to ensure mortar quality. During operation, wet mortar or dry mortar containing impurities first enters the screening system, where qualified particles are separated by screens of different mesh sizes. Then, it enters the drying system, where hot air or heating plates are used to evaporate the moisture, finally obtaining a uniform and dry finished mortar.
[0003] For example, the patent with authorization announcement number CN219291523U discloses a drying and screening device for making dry-mixed mortar from industrial waste residue. By setting up a box, feeding trough, crushing roller, transmission rod, first motor, protective shell, vibration mechanism, screen plate, cleaning mechanism, storage box, partition, heating plate and support base, it solves the problem that existing screening machines lack automatic cleaning effect on the screen plate, which causes a large number of screen holes to be blocked by material after long-term use, thereby reducing screening efficiency. It requires workers to stop the machine and spend time cleaning, which reduces the work efficiency of workers and screening efficiency. In addition, it cannot quickly dry the screened material. However, there are still areas for improvement.
[0004] During the drying process, the mortar particles in the middle have lower drying efficiency, which prolongs the overall drying time. In addition, the mortar particles roll down from the edge of the screen and fall off, with more mortar particles falling off the screen near the feed chute. This uneven distribution of mortar particles on the heating plate also prolongs the overall drying time and reduces the drying efficiency. Utility Model Content
[0005] To address the aforementioned issues, this application provides a dry mortar screening and drying device, which solves the problems of uneven distribution of mortar particles on the heating plate and poor drying effect of mortar particles in the middle position, resulting in a reduction in overall drying efficiency.
[0006] A dry mortar screening and drying device includes a box body, a screening plate for screening mortar is fixedly installed inside the box body, a drying box for drying mortar is installed below the screening plate, a linearly moving mounting frame is installed inside the drying box, and multiple sets of turning rods for turning mortar are fixedly installed outside the mounting frame, with the multiple sets of turning rods being staggered.
[0007] An electric push rod is fixedly installed on the outside of the mounting bracket, and a push plate for spreading mortar is fixedly installed on the telescopic end of the electric push rod.
[0008] Preferably, a movable motor is fixedly installed inside the chamber, and a lead screw is fixedly installed at the output end of the movable motor, with the end of the lead screw rotatably installed on the outside of the drying chamber.
[0009] Preferably, a slider is movably mounted on the outside of the lead screw, a rotary motor is fixedly mounted on the outside of the slider, and a mounting bracket is fixedly mounted on the output end of the rotary motor.
[0010] Preferably, a limiting rod is fixedly installed at the end of the mounting bracket, and a limiting groove is opened on the top of the drying oven, with the limiting rod slidably installed inside the limiting groove.
[0011] Preferably, the drying box and the outer side of the box body have two symmetrically connected discharge ports, and the inner side of the discharge ports is equipped with a sealing element.
[0012] Preferably, the screening plate is inclined, and a discharge through hole that matches the lower end of the screening plate is opened through the outer side of the box.
[0013] The beneficial effects of this utility model are as follows:
[0014] The dry powder mortar screening and drying device of this utility model uses a turning rod to turn and flush the mortar particles after they have been spread out, so that the mortar particles in the middle come into contact with hot air. Multiple sets of turning rods are arranged in a staggered manner. On the return trip, another set of turning rods comes into contact with the mortar and moves to turn and flush the mortar particles, so that the mortar particles in other positions and near the middle are exposed to the outside and come into contact with hot air, thereby improving the overall drying efficiency of the mortar particles.
[0015] The push plate moves and spreads the mortar particles evenly, resulting in a more uniform thickness and improved drying efficiency. After drying, the electric push rod drives the push plate to fit against the bottom of the drying chamber. The moving motor rotates and drives the push plate to move, pushing the mortar particles closer to the discharge port, making it easier for workers to remove the dried mortar particles.

[0024] like Figure 1-4 As shown, this utility model embodiment provides a dry mortar screening and drying device, including a box body 1. A screening plate 2 for screening mortar is fixedly installed on the inner side of the box body 1. The screening plate 2 is inclined. A discharge through hole that matches the lower end of the screening plate 2 is opened through the outer side of the box body 1. Large particles of mortar are discharged from the discharge through hole. A drying box 3 for drying mortar is installed below the screening plate 2.
[0025] In this embodiment, dry mortar is poured into the screening plate 2, small particles of mortar fall from the mesh of the screening plate 2 into the drying box 3, and large particles of mortar slide out from the discharge through hole.
[0026] Specifically, a linearly movable mounting frame 15 is installed inside the drying box 3, and multiple sets of drying rods 11 for turning over mortar are fixedly installed on the outside of the mounting frame 15. The multiple sets of drying rods 11 are installed in a staggered manner.
[0027] Specifically, a movable motor 6 is fixedly installed inside the housing 1, a lead screw 7 is fixedly installed at the output end of the movable motor 6, the end of the lead screw 7 is rotatably installed on the outside of the drying oven 3, a slider 12 is movably installed on the outside of the lead screw 7, and a rotary motor 10 is fixedly installed on the outside of the slider 12. The lead screw 7 and the slider 12 cooperate to convert the rotational motion of the movable motor 6 into the horizontal movement of the rotary motor 10, and the mounting bracket 15 is fixedly installed at the output end of the rotary motor 10.
[0028] Specifically, a limiting rod 8 is fixedly installed at the end of the mounting bracket 15, and a limiting groove 9 is opened at the top of the drying oven 3. The limiting rod 8 is slidably installed inside the limiting groove 9, and the limiting rod 8 and the limiting groove 9 cooperate to limit the movement trajectory of the mounting bracket 15.
[0029] In this embodiment, the mobile motor 6 starts, driving the lead screw 7 to rotate, which in turn drives the rotating motor 10, the turning rod 11, and the mounting frame 15 to move through the slider 12. The turning rod 11 turns and dredges the flattened mortar particles, so that the mortar particles in the middle come into contact with hot air. On the return trip, the mobile motor 6 rotates in the opposite direction, the rotating motor 10 rotates, and another set of turning rods 11 comes into contact with the mortar, moving to turn and dredge the mortar particles, so that the mortar particles in other positions and near the middle are exposed and come into contact with hot air, thereby improving the overall drying efficiency of the mortar particles.
[0030] Specifically, an electric push rod 13 is fixedly installed on the outside of the mounting frame 15, and a push plate 14 for spreading mortar is fixedly installed on the telescopic end of the electric push rod 13.
[0031] In this embodiment, the moving motor 6 starts and drives the electric push rod 13, push plate 14, and mounting bracket 15 to move. The push plate 14 moves and spreads the mortar particles, making the thickness more uniform and improving the drying efficiency.
[0032] Specifically, the drying box 3 and the box body 1 have two symmetrically connected discharge ports 5 on their outer sides for discharging the dried mortar particles. The discharge ports 5 are equipped with sealing elements 4 to ensure that the mortar particles do not overflow during the drying process.
[0033] In this embodiment, after drying is completed, the working group removes the seal 4, rotates the motor 10 to make the push plate 14 contact the mortar particles, the telescopic end of the electric push rod 13 extends, causing the push plate 14 to fit against the bottom of the inner side of the drying box 3, and the moving motor 6 rotates to move the push plate 14, pushing the mortar particles closer to the discharge port 5, so that the workers can easily take out the dried mortar particles.
[0034] Specific working methods:
[0035] Dry mortar is poured into screening plate 2. Small mortar particles fall from the mesh of screening plate 2 into drying box 3, while large mortar particles slide out through the discharge hole.

In turn, the slider 12 drives the rotating motor 10, the turning rod 11, the electric push rod 13, the push plate 14, and the mounting frame 15 to move. The push plate 14 moves to flatten the mortar particles, making the thickness more uniform and improving the drying efficiency.
[0037] The turning rod 11 turns and dries the flattened mortar particles, allowing the mortar particles in the middle to come into contact with hot air. On the return trip, the moving motor 6 rotates in the opposite direction, and the rotating motor 10 rotates, so that the push plate 14 does not come into contact with the mortar, while another set of turning rods 11 comes into contact with the mortar. The moving rod turns and dries the mortar particles, allowing the mortar particles in other positions and near the middle to be exposed and come into contact with hot air, thereby improving the overall drying efficiency of the mortar particles.
[0038] After drying, the work team removes the seal 4, rotates the motor 10 to make the push plate 14 contact the mortar particles, the telescopic end of the electric push rod 13 extends, causing the push plate 14 to fit against the bottom of the inner side of the drying box 3, the moving motor 6 rotates to move the push plate 14, pushing the mortar particles closer to the discharge port 5, making it easier for the staff to take out the dried mortar particles.
