Description

Technical Field

[0001] This utility model relates to the field of recycled concrete production technology, and in particular to a raw material humidification device for recycled concrete production. Background Technology

[0002] Recycled concrete production refers to the process of recycling, crushing, washing, and grading waste concrete blocks, mixing them with graded aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. to make new concrete. Humidification of raw materials in recycled concrete production refers to the operation of using a humidification device to moisten the surface of recycled concrete blocks during production in order to reduce the occurrence of cracks caused by moisture loss in the recycled concrete blocks.

[0003] In the prior art, a humidification device for raw materials in concrete production, as described in patent publication number CN222270762U, includes a raw material placement area and a frame. The device is characterized by further including two sets of spray pipes, each positioned at the bottom of the frame above the raw material placement area. Atomizing nozzles are evenly distributed at the bottom of each spray pipe. The device automatically adjusts the spray range of the atomizing nozzles by incorporating the raw material placement area, an automatic translation mechanism, the frame, a water tank, the spray pipes, and the atomizing nozzles, eliminating the need for manual operation. However, traditional devices often employ simple top spraying or direct watering methods, making it difficult for moisture to effectively penetrate the aggregate, easily resulting in a "wet outside, dry inside" phenomenon. Furthermore, the surface of recycled aggregates is covered with a large amount of powder, which easily generates severe dust during humidification, especially during simple pouring and mixing. Existing equipment typically lacks an efficient, integrated dust removal system, leading to dust permeating the production site, polluting the environment, endangering the health of operators, and ultimately reducing the humidification effect. Utility Model Content

[0004] The purpose of this invention is to provide a humidification device for raw materials used in the production of recycled concrete. This addresses the problem that traditional devices often use simple top spraying or direct water sprinkling, which makes it difficult for moisture to effectively penetrate into the aggregate, easily causing a "wet outside, dry inside" phenomenon. Furthermore, the surface of recycled aggregate is covered with a large amount of powder, which easily generates serious dust during the humidification process, especially during simple pouring and mixing. Existing equipment usually lacks an efficient and integrated dust removal system, resulting in dust filling the production site, which not only pollutes the environment but also endangers the health of operators, thereby reducing the humidification effect.

[0005] To achieve the above objectives, a humidification device for raw materials used in the production of recycled concrete is provided, comprising a base plate, an operating frame fixed to the top of the base plate, a partition fixed to the center of the inner side of the operating frame, a humidification water tank fixed to the left side of the partition, two water inlet pipes fixed to the outer left side of the humidification water tank, one end of each water inlet pipe penetrating into the inner side of the humidification water tank, and the other end of each water inlet pipe penetrating into the outer left side of the operating frame, a dust collection box disposed on the outer right side of the operating frame, a support plate fixed to the bottom of the dust collection box, the bottom surface of the support plate being flush with the ground, and the dust collection box being fixedly connected to the inner side of the operating frame via an air inlet pipe, one end of the air inlet pipe penetrating into the inner side of the dust collection box, and the other end penetrating into the inner side of the operating frame, an air outlet pipe fixed to the outer right side of the dust collection box, and an air pump disposed at the top of both the air outlet pipe and the air inlet pipe.

[0006] According to the aforementioned humidification device for raw materials used in the production of recycled concrete, an upper water outlet pipe is fixed to the outer right side of the humidification water tank. One end of the upper water outlet pipe extends through the inner side of the humidification water tank, and the other end extends through the outer right side of the partition and is fixedly connected to the upper right side of the inner side of the operating frame. Multiple lower water outlet pipes are fixed to the bottom of the upper water outlet pipe near the inner right side of the operating frame, and a spray plate is fixed to the bottom of each of the multiple lower water outlet pipes.

[0007] According to the aforementioned humidification device for raw materials used in the production of recycled concrete, a drive motor is fixed to the lower left side of the operating frame, a stirring rod is rotatably connected to the center of the humidification tank, multiple branch rods are fixed to the outside of the stirring rod, and the output end of the drive motor extends through the inside of the humidification tank and is fixedly connected to the outside of the stirring rod via a coupling.

[0008] According to the aforementioned humidification device for raw materials used in the production of recycled concrete, multiple sleeve plates are fixedly attached to the outside of the water outlet pipe near the right side of the inside of the operating frame, and the tops of the multiple sleeve plates are fixedly connected to the top of the inside of the operating frame.

[0009] According to the aforementioned humidification device for raw materials used in the production of recycled concrete, water pumps are installed on the top sides of the outlet pipe and the two inlet pipes.

[0010] According to the aforementioned humidification device for raw materials used in the production of recycled concrete, a cover is provided on the top of the humidification tank, and reinforcement holes are provided around the top surface of the cover, with multiple reinforcement holes extending into the interior of the humidification tank.

[0012] According to the aforementioned humidification device for raw materials used in the production of recycled concrete, two protective doors are rotatably connected to the outside of the operating frame.

[0013] The above-mentioned solutions offer the following benefits: The design of the dust collection box allows for the active extraction of dust generated within the operating frame during humidification, which is then transported to the dust collection box for treatment. This solves the problem of dust permeation at traditional humidification sites, significantly improving the working environment and protecting worker health. The design of the mixing structure ensures thorough mixing of the water used for humidification with additives (such as water-reducing agents and air-entraining agents). The multi-point, top-down spraying method, compared to a single water pipe, provides more even coverage of the aggregate pile surface, laying the foundation for subsequent uniform penetration and initially improving the "wet outside, dry inside" problem.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a humidification device for raw materials used in the production of recycled concrete. It includes a base plate 1, an operating frame 2 fixed to the top of the base plate 1, a partition 3 fixed to the center of the inner side of the operating frame 2, a humidification water tank 4 fixed to the left side of the partition 3, two water inlet pipes 5 fixed to the outer left side of the humidification water tank 4, one end of each water inlet pipe 5 penetrating into the inner side of the humidification water tank 4, and the other end of each water inlet pipe penetrating into the outer left side of the operating frame 2. A dust collection box 6 is located on the outer right side of the operating frame 2, a support plate 7 fixed to the bottom of the dust collection box 6, the bottom surface of the support plate 7 being flush with the ground, and the dust collection box 6 being fixedly connected to the inner side of the operating frame 2 via an air inlet pipe 8, one end of the air inlet pipe 8 penetrating into the inner side of the dust collection box 6, and the other end penetrating into the inner side of the operating frame 2. An air outlet pipe 9 is fixed to the outer right side of the dust collection box 6, and a suction pump 10 is installed at the top of both the air outlet pipe 9 and the air inlet pipe 8. In the prior art, traditional devices often employ simple top spraying or direct spraying. The traditional water spraying method makes it difficult for water to effectively penetrate into the aggregate, easily causing a "wet outside, dry inside" phenomenon. Moreover, the surface of recycled aggregate is covered with a large amount of powder, which easily generates serious dust during the humidification process, especially during simple pouring and stirring. Existing equipment usually lacks an efficient and integrated dust removal system, resulting in dust filling the production site, which not only pollutes the environment but also endangers the health of operators, thereby reducing the humidification effect. To address this problem, a dust collection box 6 can be designed to actively suck up the dust generated in the operating frame 2 during humidification and guide it into the dust collection box 6 for treatment. This solves the problem of dust filling the traditional humidification site, greatly improves the working environment, protects the health of workers, and separates the humidification functional area (left side) and the dust removal functional area (right side) through a partition 3, but organically connects them through pipelines, making the equipment structure compact and the functional areas clearly defined.

[0024] A water outlet pipe 11 is fixed on the right side of the humidifying water tank 4. One end of the water outlet pipe 11 extends into the inside of the humidifying water tank 4, and the other end extends into the right side of the partition 3. It is fixedly connected to the upper right side of the inside of the operating frame 2. Multiple water outlet pipes 12 are fixed near the bottom of the water outlet pipe 11 on the right side of the inside of the operating frame 2. Each of the multiple water outlet pipes 12 has a spray plate 13 fixed at its bottom. By using a multi-point, top-down spraying method, the surface of the aggregate pile can be covered more evenly than a single water pipe, laying the foundation for subsequent uniform penetration and initially improving the problem of "external wetness and internal dryness".

[0025] A drive motor 14 is fixed to the lower left side of the operating frame 2. A stirring rod 15 is rotatably connected to the center of the humidifying water tank 4. Multiple branch rods 16 are fixed to the outside of the stirring rod 15. The output end of the drive motor 14 passes through the inside of the humidifying water tank 4 and is fixedly connected to the outside of the stirring rod 15 through a coupling, so as to achieve full mixing of the water used for humidification and the additives. The additives used, such as water-reducing agents and air-entraining agents, can improve the fluidity, durability and strength of concrete.

[0026] Multiple socket plates 17 are fixed to the outside of the water outlet pipe 11 near the inside right side of the operating frame 2. The top of the multiple socket plates 17 is fixedly connected to the top of the inside of the operating frame 2, which ensures the stability and reliability of the water supply pipeline and extends the service life of the equipment.

[0027] Water pumps 18 are installed on the top side of the outlet pipe 11 and the two inlet pipes 5, which realizes active control of water supply switch and flow rate. Operators can accurately control the amount of water added according to the amount and dryness of aggregate, avoiding the unstable flow and waste caused by relying on water pressure or gravity water supply in the traditional method.

[0028] The humidifying water tank 4 is provided with a cover 19 on the top. The cover 19 has reinforcement holes 20 on all four sides. The reinforcement holes 20 extend into the interior of the humidifying water tank 4. The cover 19 facilitates cleaning and maintenance of the interior of the humidifying water tank 4. The reinforcement holes 20 can be used to tightly connect the cover 19 to the humidifying water tank 4 with bolts or other fasteners, ensuring the airtightness during stirring.

[0029] A soil loading frame 21 is provided on the outer right side of the partition 3. The soil loading frame 21 is slidably connected to the bottom inner side of the operating frame 2. The slidable soil loading frame 21 is used to place the concrete that needs to be humidified, and it can be pulled out after humidification is completed, which greatly simplifies the cleaning and maintenance work.

[0030] The operating frame 2 has two protective doors 22 connected to its external rotating structure, which makes the entire humidification and dust removal area a relatively enclosed space. This ensures production safety, prevents personnel from contacting moving parts, and facilitates operators to observe the internal working conditions and carry out daily operations.

[0031] Working principle: Open the protective door 22 on the right side of the operating frame 2, put the recycled concrete aggregate that needs to be humidified into the soil loading frame 21, close the protective door 22 to form a relatively sealed working space inside the operating frame 2, preparing for the subsequent dust removal process. Then, the external water source is connected through two water inlet pipes 5 and controlled by the corresponding water pump 18. Then, turn on the water pump 18 connected to the water inlet pipe 5 to introduce external clean water into the humidification water tank 4. Start the drive motor 14 to drive the stirring rod 15 and the dividing rod 16 to rotate at high speed in the humidification water tank 4 to ensure that the water in the tank is evenly mixed, prevent the additives (water reducing agent or air entraining agent) from settling, and provide a uniform water source for pumping. Turn on the water pump 18 connected to the water outlet pipe 11 to pump the stirred water in the humidification water tank 4 into the water outlet pipe 11. The water flow is then divided into multiple water outlet pipes 12, and finally flows out evenly from the bottom spray plate 13 in the form of spraying or dripping. The water flow is evenly sprayed from top to bottom onto the soil loading frame 21. The recycled aggregate inside is covered by multiple water spray plates 13, achieving large-area coverage and avoiding humidification dead zones caused by a single water pipe. At the start of the humidification process, the air pump 10 is activated, and the air inlet pipe 8 powerfully sucks out the dust and water vapor mixture generated during the humidification process. The extracted dust-laden gas is sent into the dust collection box 6, which is usually equipped with filter bags and filter cartridges to filter and purify the gas. The purified clean air is discharged into the atmosphere through the air outlet pipe 9 under the action of the corresponding air pump 10, effectively suppressing dust dispersion and ensuring a clean working environment. After the predetermined humidification time or water volume is reached, the water pump 18 is turned off in sequence, the drive motor 14 and the air pump 10 are turned off, the protective door 22 is opened, and the evenly humidified recycled aggregate is pulled out together with the soil loading frame 21 and transferred to the next production process. The box cover 19 is opened to clean and maintain the inside of the humidification water tank 4.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
