Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent technology, and in particular to a drying device for preparing water-reducing agents. Background Technology

[0002] Water-reducing agents are concrete admixtures that can reduce the amount of mixing water while maintaining the slump of concrete. During the production of water-reducing agents, the water content after extrusion may be relatively high, so drying equipment is generally required to dry the extruded water-reducing agent material to facilitate subsequent storage, transportation and use.

[0003] However, most current water-reducing agent drying equipment involves piling the water-reducing agent inside a drying chamber and then heating it to dry. This method can easily lead to uneven drying inside and outside the water-reducing agent, resulting in poor drying effect.

[0004] Therefore, a drying device for preparing water-reducing agents is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To overcome the shortcomings of existing technologies, a drying device for the preparation of water-reducing agents is proposed. This addresses the problem that most current water-reducing agent drying equipment involves accumulating the water-reducing agent inside a drying chamber and then heating it for drying. This method often results in uneven drying of the water-reducing agent inside and out, leading to poor drying results.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: This utility model proposes a drying device for preparing water-reducing agents, including...

[0009] The outer box and the inner box are provided. The inner box is installed inside the outer box by connecting and fixing blocks. The upper outer side of the outer box is provided with a discharge port that penetrates the inner box, and the bottom of the inner box is provided with a discharge port that penetrates the outer box.

[0010] Furthermore, the top of the outer box and the inner box are horizontally cut with an openable lid;

[0011] The box cover has a rotating shaft in the middle that passes through the upper and lower ends of the outer and inner boxes. The upper and lower ends of the rotating shaft are rotatably connected to the connecting and fixing blocks between the outer and inner boxes through bearings. A motor is installed at the top of the box cover and connected to the rotating shaft. The rotating shaft has a downward-through air groove inside. A hot air blower is installed at the bottom of the outer box, and the air supply end of the hot air blower passes through the connecting and fixing blocks between the outer and inner boxes and is located at the bottom of the air groove. Several rotating rods are installed on the outside of the rotating shaft, and air pipes are installed inside the rotating rods that pass through the air groove. Several through air holes are provided at the bottom of the air pipes.

[0012] Furthermore, the outer ring of the rotating rod is wrapped with a filter-type protective layer.

[0013] Furthermore, a scraper is installed on the outer side of the rotating rod to contact the inner wall of the inner box.

[0014] Furthermore, a breathable cavity is formed between the outer box and the inner box, and several air intake holes are provided at the top of the inner box at the bottom end of the box cover.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. In this utility model, the water-reducing agent material is fed into the inner box through the feeding port. Hot air is fed into the inner box through the opening at the lower end of the air groove by the hot air blower, and the hot air is fed into the inner box through the air hole at the bottom of the air pipe. This heats and dries the material. The rotating shaft driven by the motor turns the material over, avoiding uneven heating inside and outside the material due to the material being left still, thus making the material drying effect better.

[0020] Furthermore, a scraper is connected to the side of the rotating rod, which scrapes the material on the inner wall of the inner box to prevent it from sticking to the inner wall due to heat, thus making cleaning more convenient and improving work efficiency.

[0021] 2. In this utility model, the dried hot air is introduced into the cavity between the outer and inner boxes through the air intake hole. When the hot air passes through the cavity, it heats the inner wall of the inner box, resulting in better internal heating and faster drying rate.

[0022] Furthermore, hot air is introduced into the adsorption tube through the air duct, and the moisture in the hot air is adsorbed by the adsorption layer. Then, it is sucked out by the hot air and reused. This cycle of heat utilization makes the heating effect better, reduces heat loss, and speeds up the drying process. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0030] Please see Figures 1-4 This utility model provides a drying device for preparing water-reducing agents, including an outer box 1 and an inner box 8. The inner box 8 is installed inside the outer box 1 through a connecting fixing block 9, so that the two boxes form a cavity. The upper outer side of the outer box 1 is provided with a discharge port 110 that penetrates the inner box 8 to input the water-reducing agent material into the inner box 8 for drying. The bottom of the inner box 8 is provided with a discharge port 4 that penetrates the outer box 1 to discharge the dried material outward. A controller 2 is installed on the outside of the outer box 1. The controller 2 purchased externally can facilitate the user to operate the electrical components in the device, making the operation more convenient. The bottom of the outer box 1 is provided with a support foot 3 to raise the bottom and facilitate the installation of other components and the material feeding and receiving work.

[0031] Furthermore, the top of the outer box 1 and the inner box 8 are horizontally cut with an openable cover 5, which makes it easy to open the top to remove the internal protective layer 15 and filter layer 18 for cleaning and replacement, and also to clean the cavity. The top of the cover 5 is symmetrically equipped with handles 6 on both sides to facilitate opening the cover 5 with force.

[0032] A rotating shaft 10 is located in the middle of the cover 5, passing through the upper and lower ends of the outer box 1 and the inner box 8. The upper and lower ends of the rotating shaft 10 are rotatably connected to the connecting fixing block 9 between the outer box 1 and the inner box 8 via bearings. The bottom end of the rotating shaft 10 is slidably connected to the inner side of the bearing of the connecting fixing block 9, which facilitates the removal of the rotating shaft 10 for cleaning under the action of the cover 5. A motor 7 is installed at the top of the cover 5 and connected to the rotating shaft 10. The rotating shaft 10 has a downward-penetrating air groove 11 inside. A hot air blower 111 is installed at the bottom of the outer box 1, and the air supply end of the hot air blower 111 passes through the connecting fixing block 9 between the outer box 1 and the inner box 8 and is located at the bottom of the air groove 11. This prevents the air supply end of the hot air blower 111 from being fixedly connected to the rotating shaft 10, thus avoiding the rotating shaft 10 from being fixedly connected to the outer box 1. In cases where fixed installation is inconvenient, the hot air generated by the hot air blower 111 can be supplied to the inner chamber 8 through the air trough 11 for heating and drying. Several rotating rods 12 are installed on the outside of the rotating shaft 10. When the rotating shaft 10 is driven by the motor 7 to rotate, the rotating rods 12 agitate the material in the inner chamber 8, preventing uneven drying caused by the material remaining still. The rotating rods 12 are equipped with air pipes 13 that pass through the air trough 11. The bottom of the air pipes 13 is equipped with several through-holes 14, which allow hot air to enter the inner chamber 8 through the air holes 14. The vertical arrangement of the rotating rods ensures more complete contact between the hot air and the material, resulting in better drying effect. The outer ring of the rotating rods 12 is wrapped with a filter-type protective layer 15 to reduce the amount of material entering the air holes 14.

[0033] Preferably, a scraper 16 is installed on the outside of the rotating rod 12 to contact the inner wall of the inner box 8, so that the scraper 16 scrapes the material adhering to the inner wall of the inner box 8 when rotating, thereby avoiding the situation where the material adheres and causes subsequent cleaning inconvenience and affects the drying effect.

[0034] Preferably, a breathable cavity is formed between the outer box 1 and the inner box 8, allowing hot air to flow inside. This flow of hot air heats the inner box 8, improving the internal heating and drying effect. Several air intake holes 19 are located at the top of the inner box 8, near the bottom of the cover 5, to draw the dried hot air upwards. An adsorption pipe 112 is installed at the bottom of the outer box 1, with a guide pipe 114 on one side of the adsorption pipe 112 penetrating the outer box 1 within the cavity. The air intake end of the hot air blower 111 penetrates the other side of the adsorption pipe 112. An adsorption layer 113 is provided inside the adsorption pipe 112. The adsorption layer 113 can be made of materials such as activated carbon to absorb moisture, reducing the reuse of moisture. Furthermore, a ventilation hole 19 is provided on the outer side of the adsorption pipe 112. The open side door facilitates the replacement of the internal adsorption layer 113. This allows the hot air, dried internally under the suction of the hot air blower 111, to enter the cavity through the air intake 19 and then be filtered through the lower air guide pipe into the adsorption layer 113. The air is then reintroduced into the inner chamber 8 by the hot air blower 111 for drying. This circulation of heat reduces heat loss and increases work efficiency. Several mounting blocks 17 are provided at the top of the inner wall of the inner chamber 8, and a filter layer 18 is provided at the upper end of the mounting blocks 17. The rotating shaft 10 passes through the middle of the filter layer 18. The filter layer 18 prevents the material from being sucked out during drying and agitation, and prevents the material from entering the cavity through the air intake 19.

[0035] Working principle: In use, first connect the motor 7, hot air blower 111 and controller 2, and connect them to an external power source. Then, input the water-reducing agent material into the inner box 8 through the feed port 110. With the hot air blower 111 supplying hot air, the hot air is input into the air groove 11 inside the rotating shaft 10, and output into the inner box 8 through the air pipe 13 and air hole 14 inside the rotating rod 12 on the outside of the air groove 11 for drying. Under the rotation of the rotating shaft 10 driven by the motor 7, the rotating rod 12 actuates the material for drying. Under the suction of the hot air blower 111, the hot air generated during drying is input upward through the air suction hole 19 into the cavity, and then into the adsorption tube 112 through the air guide pipe 114. After the moisture is adsorbed by the adsorption layer 113, it is then reinjected into the air groove 11 through the hot air blower 111. This practical heat recycling completes the work.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
