Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material processing technology, and in particular to a waterproof material processing and drying equipment. Background Technology
[0002] In the fields of building, engineering and industrial waterproofing, powdered or fine granular waterproofing materials are widely used in various waterproofing projects. These materials often contain a certain amount of moisture or volatile components during production or storage. If they are not fully dried, their performance, storage stability and construction quality will be seriously affected. Therefore, it is particularly necessary to carry out efficient and uniform drying treatment in the processing of waterproofing materials.
[0003] Patent CN220269900U discloses a powder drying device. This device delivers powder through the inner cavity of a hopper, allowing the powder to fall into a barrel cavity via a discharge column. This simple feeding and material handling process involves opening a bag of powder and pouring it into the hopper. A threaded connection between the screw and plug seals the screw opening. After the screw is opened, the dried powder falls into the cavity of a rack for collection. Once the rack is full, it is removed and replaced with a new one, achieving rapid drying. While the device aims for fast and simple feeding and discharging, it still has some shortcomings in practical applications. The lack of a dedicated exhaust channel means that a large amount of water vapor generated during the heating and drying process cannot be discharged in time, accumulating inside the equipment. As the water vapor cools and forms condensate on the inner wall of the equipment, it may re-adsorb onto the powder surface, causing the material to become damp or even clump, severely affecting product quality. Furthermore, steam retention leads to excessively high humidity inside the equipment, prolonging drying time and reducing overall equipment efficiency.
[0004] Therefore, there is an urgent need to provide a waterproof material processing and drying equipment with an automatic venting structure. Utility Model Content
[0005] In order to overcome the shortcomings of existing powder drying devices that lack an effective exhaust structure, which prevents water vapor generated during the drying process of powdered waterproof materials from being discharged in time and easily forms condensate inside the equipment, thus causing secondary contamination of the materials, this utility model provides a waterproof material processing and drying device with an automatic exhaust structure.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: a waterproof material processing and drying device, comprising a support frame, an outer barrel fixedly mounted on the support frame, an inner barrel disposed inside the outer barrel, an annular sandwich formed between the inner barrel and the outer barrel, an electric heating tube disposed inside the annular sandwich, the electric heating tube being arranged around the sandwich and closely attached to the outer wall of the inner barrel, a controller mounted on the lower side of the outer wall of the outer barrel, the controller being connected to the electric heating tube via an electric wire, the electric heating tube being turned on and off, an electromagnetic valve mounted at the bottom of the inner barrel, and symmetrically distributed exhaust pipes disposed at the top of the inner barrel, each exhaust pipe having a hinge seat fixedly connected to its top, a cover plate hinged to the hinge seat, a spiral spring sleeved at the hinge joint between the cover plate and the hinge seat, one end of the spiral spring being fixed to the hinge seat and the other end being fixed to the cover plate.
[0007] As an improvement to the above solution, a fixed base is provided at the top of the inner barrel, and a servo motor is installed on the fixed base. The output shaft of the servo motor rotates through the top of the inner barrel, and its end is connected to a spiral stirring rod, which is located inside the inner barrel.
[0008] As an improvement to the above solution, a support base is fixed to the lower side of the outer barrel, and a conveying pump is installed on the support base. The output end of the conveying pump is connected to and communicates with a first conveying pipe, which is connected to the top of the inner barrel. The input end of the conveying pump is connected to and communicates with a second conveying pipe.
[0009] As an improvement to the above solution, a filter screen is installed inside the exhaust pipe.
[0010] As an improvement to the above solution, a corrugated telescopic pipe is connected to the end of the second conveying pipe.
[0011] As an improvement to the above solution, the controller is provided with a rotatable protective cover.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. By symmetrically setting exhaust pipes on the top of the inner barrel and installing an automatic cover structure with a spiral spring at the exhaust port, the structure automatically closes when there is no air pressure to prevent external dust from entering. When the pressure of the inner barrel increases, the cover automatically opens to exhaust air, ensuring that water vapor is discharged in time, reducing internal humidity and air pressure, and preventing materials from becoming damp and clumping, thus ensuring product quality.
[0013] 2. By installing a spiral stirring rod inside the inner drum, the powdered material can be continuously stirred during the drying process, effectively preventing material accumulation and uneven local heating, enhancing heat transfer efficiency, and accelerating the evaporation rate of moisture, thereby significantly improving the overall drying efficiency and drying quality.
[0014] 3. Equipped with a conveying pump and conveying pipeline mechanism, continuous feeding from the storage equipment to the inner barrel can be realized. At the same time, a solenoid valve is installed at the bottom of the inner barrel to control the discharge of dried material, making the entire drying process more automated and efficient, and reducing the intensity of manual labor.

Detailed Implementation
[0021] 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.
[0022] Example 1: See Figures 1-3A waterproof material processing and drying device includes a support frame 1, on which an outer barrel 101 is fixedly mounted. Inside the outer barrel 101 is an inner barrel 2 capable of holding powdered waterproof material. An annular sandwich is formed between the inner barrel 2 and the outer barrel 101. An electric heating tube 4 is disposed inside the annular sandwich, arranged around the sandwich and closely attached to the outer wall of the inner barrel 2 to achieve uniform heating of the material. A controller 401 is mounted on the lower side of the outer wall of the outer barrel 101. The controller 401 is connected to the electric heating tube 4 via an electric wire and is used to control the opening and closing of the electric heating tube 4. A protective cover 18 is rotatably mounted on the controller 401 to cover the controller 401 and prevent accidental operation of the operation button or lifting of the device. To ensure safety and reliability, the inner drum 2 is equipped with a solenoid valve 3 at the bottom for controlling material discharge. The top of the inner drum 2 has symmetrically distributed exhaust pipes 5 for discharging water vapor generated during the drying process. Each exhaust pipe 5 has a filter screen 16 inside to prevent dust from the powdered waterproof material from being discharged with the steam, while also preventing external impurities from entering the inner drum 2, ensuring material cleanliness and safe equipment operation. Each exhaust pipe 5 has a hinge seat 7 fixed to its top, and a cover plate 6 is hinged to the hinge seat 7. A spiral spring 8 is fitted at the hinge between the cover plate 6 and the hinge seat 7. One end of the spiral spring 8 is fixed to the hinge seat 7, and the other end is fixed to the cover plate 6, allowing the cover plate 6 to automatically close when no external force is applied, preventing external dust from entering the inner drum 2.
[0023] When using this device, the controller 401 is activated, which controls the electric heating element 4 to be energized and heated. The heat is transferred to the inner drum 2 through the interlayer, thereby uniformly heating the powdered waterproof material inside the drum. At the same time, the controller 401 monitors and adjusts the heating power of the electric heating element 4 in real time to ensure that the temperature inside the inner drum 2 is maintained within the set range. During the heating process, the moisture in the powdered waterproof material gradually evaporates into water vapor. In the initial stage, due to the low air pressure inside the inner drum 2, the cover 6 remains closed under the action of the spiral spring 8 to prevent external dust from entering. When the air pressure inside the inner drum 2 rises to the set threshold, the steam pressure pushes the cover 6 to rotate around the hinge seat 7, causing it to open automatically. The water vapor is discharged through the exhaust pipe 5, thereby effectively reducing the humidity inside the drum, improving the drying efficiency, and maintaining an appropriate pressure level inside the inner drum 2. The cover 6 can automatically reset and close after venting, preventing dust from entering the equipment when the machine is stopped, improving the cleanliness and service life of the equipment. After drying is completed, the solenoid valve 3 at the bottom of the inner drum 2 is opened, and the dried powdered waterproof material is discharged through the discharge port, completing the entire drying process.
[0024] Example 2: Based on Example 1, please refer to... Figure 4The inner barrel 2 is provided with a fixed base 9 at the top, and a servo motor 10 is installed on the fixed base 9. The output shaft of the servo motor 10 rotates through the top of the inner barrel 2, and its end is connected to a spiral stirring rod 11, which is located inside the inner barrel 2.
[0025] During the drying process, the servo motor 10 is started, and the output shaft of the servo motor 10 drives the spiral stirring rod 11 to rotate inside the inner barrel 2. The continuous rotation of the spiral stirring rod 11 can effectively disperse the powdery waterproof material, prevent the material from accumulating and clumping, and at the same time promote the uniform distribution of heat in the material and accelerate the evaporation rate of moisture, thereby significantly improving the drying efficiency and drying quality. In addition, the stirring process also helps the material to have full contact with the hot air, further improving the heat transfer efficiency and ensuring the consistency and stability of the drying effect.
[0026] Please see Figure 5 The lower side of the outer barrel 101 is fixedly connected to a support base 12. A conveying pump 13 is installed on the support base 12. The output end of the conveying pump 13 is connected to and communicates with a first conveying pipe 14. The first conveying pipe 14 is connected to the top of the inner barrel 2 and is used to convey powdered waterproof material into the inner barrel 2 for drying. The input end of the conveying pump 13 is connected to and communicates with a second conveying pipe 15 for connecting to external storage equipment to achieve continuous material supply. The end of the second conveying pipe 15 is connected to a corrugated expansion pipe 17 to compensate for installation errors or displacement between equipment and facilitate loading, unloading and maintenance.
[0027] The external storage device is connected to this device through the corrugated expansion tube 17. The powdered waterproof material in the external storage device enters the conveying pump 13 through the second conveying pipe 15. Under the action of the conveying pump 13, the material is pressurized and conveyed to the top of the inner barrel 2 through the first conveying pipe 14. The powdered material enters the interior of the inner barrel 2 and is ready for drying. The feeding process does not require manual intervention, realizing a continuous and automated operation process.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
