Description
Technical Field
[0001] The utility model relates to the technical field of concrete slurry making devices, in particular to a self-cleaning concrete block slurry making device. Background Art
[0002] The pulping device of concrete blocks is an indispensable key equipment in the production process of concrete blocks. The device is mainly used to prepare the slurry required for concrete blocks. Its performance is directly related to the quality and production efficiency of the blocks. Generally speaking, the pulping device includes core components such as a mixing system, a water supply system, and a control system. Through precise proportioning and efficient mixing, raw materials such as cement, aggregates, and additives are mixed into a uniform slurry. During the pulping process, the pulping device can ensure the stability and fluidity of the slurry to meet the needs of different block production. At the same time, modern pulping devices also focus on energy saving, environmental protection, and intelligence, and use advanced control technology and cleaning processes to reduce energy consumption and emissions, and improve production efficiency and product quality. In addition, some advanced pulping devices are also equipped with a self-cleaning function, which can automatically clean up residual slurry and impurities, reduce downtime and labor maintenance costs, and further improve production efficiency and equipment stability.
[0003] The self-cleaning concrete block pulping device is of indispensable importance in the concrete block production process. First, its automatic cleaning function greatly reduces production interruptions caused by shutdown cleaning and significantly improves production efficiency. Secondly, the device ensures that the slurry produced each time is fresh and uniform, thereby ensuring the stability and reliability of the quality of concrete blocks. In addition, through regular automatic cleaning, the self-cleaning pulping device can effectively reduce wear and corrosion inside the equipment, extend the service life of the equipment, and reduce production risks caused by equipment failure. What is more worth mentioning is that the self-cleaning pulping device also reduces maintenance costs. Traditional pulping devices require manual regular cleaning, which not only increases labor costs, but may also affect equipment performance due to incomplete cleaning. The self-cleaning pulping device reduces manual intervention and improves the stability and reliability of the equipment. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-Figure 2 A self-cleaning concrete block pulping device comprises a stirring device 1 and a pulping cylinder 2. The stirring device 1 is provided with rotor blades and is driven to rotate by a motor. The stirring device 1 is arranged above the pulping cylinder 2, and the rotor blades rotate in the pulping cylinder 2. A discharge channel 21 and an air inlet channel 22 are arranged below the pulping cylinder 2. The air inlet channel 22 and the discharge channel 21 are coaxially arranged, and the air inlet channel 22 is on the outer circle of the discharge channel 21. An air inlet 23 is provided at the connection between the air inlet channel 22 and the bottom of the pulping cylinder 2. The air inlet 23 and the discharge channel 21 can be opened and closed. The air inlet channel 22 is connected to an external air pump, and can introduce intermittent pulse airflow into the pulping cylinder 2.
[0018] Furthermore, when cleaning is required, clean water is added to the pulping cylinder 2, and intermittent pulse airflow is introduced into the air inlet channel 22. The air inlet 23 is opened in coordination with the pulse airflow to allow the airflow to enter the pulping cylinder 2. At the same time, the discharge channel 21 also cooperates with the air inlet 23 to open the channel to allow part of the liquid to flow out, so that the fluid on the outside of the pulping cylinder 2 flows upward, and the fluid in the center flows downward to form a collapse, and the fluid on the outside flows inward to form a vortex ring that moves upward. The rotating nature of the vortex ring causes the flow velocity in its core area to be lower, while the flow velocity in the edge area is higher. The inner wall of the pulping cylinder 2 is cleaned by the high-speed vortex flowing on the outside, and larger dirt is impacted by the high-speed fluid flowing on the outside, and is peeled off and flows to the center, where it is concentrated and discharged through the discharge channel 21. The high-speed rotation of the vortex ring and the impact of the airflow can quickly and effectively remove the residual slurry and impurities on the inner wall of the pulping cylinder. Compared with traditional cleaning methods, vortex ring cleaning is more efficient, greatly shortens the cleaning time, and improves production efficiency.
[0019] An external connecting ring 3 is provided on the outside of the pulping cylinder 2, an air pump is provided in the external connecting ring 3, and air injection ports 201 are densely distributed on the inner wall of the pulping cylinder 2, the air injection ports 201 are connected to the air pump, and bubbles are injected into the pulping cylinder 2 through the air injection ports 201, and the stirring device 1 is used to rotate and stir to break large bubbles, and the bubbles are attached to the inner wall of the pulping cylinder 2 through rotation, and the bubbles generated when the bubbles attached to the inner wall are broken are used to remove the more stubborn stains on the inner wall of the pulping cylinder 2.
[0020] An ultrasonic transmitter is arranged in the outer ring 3 and is directed toward the pulping cylinder 2. The ultrasonic transmitter can further break the bubbles into small bubbles and generate vibrations. Such high-frequency vibrations can generate strong impact force, loosen and remove stubborn stains and impurities attached to the inner wall, thereby achieving deep cleaning. At the same time, it helps the gas dissolved in the liquid in the cylinder to precipitate and generate more bubbles.
[0021] A conical baffle 11 is provided above the rotor blade to buffer the liquid or raw material poured into the barrel to avoid direct impact on the rotor blade, which may cause the rotor blade to break.

When the pulping cylinder 2 is completely pulped and needs to be cleaned, add clean water to the pulping cylinder 2, and let intermittent pulse airflow into the air inlet channel 22. The air inlet 23 opens in coordination with the pulse airflow, so that the airflow enters the pulping cylinder 2. At the same time, the discharge channel 21 also opens the channel in coordination with the air inlet 23, so that part of the liquid flows out, so that the fluid outside the pulping cylinder 2 flows upward, and the fluid in the center flows downward, forming a collapse, and the outer fluid flows inward, forming a vortex ring that moves upward, and the rotation of the vortex ring The quality causes the flow velocity in the core area to be lower, while the flow velocity in the edge area to be higher. The inner wall of the pulping cylinder 2 is cleaned by the high-speed flow vortex on the outside. The larger dirt is impacted by the high-speed flow of the fluid on the outside, is peeled off and flows to the center, where it is concentrated and discharged through the discharge channel 21. After the internal sewage is discharged, water is added again, and bubbles are injected into the pulping cylinder 2 through the air injection port 201 through the air pump in the external ring 3. The stirring device 1 is used to rotate and stir to break the large bubbles, and the bubbles are attached to the inner wall of the pulping cylinder 2 through rotation.
