Description

Technical Field

[0001] This utility model relates to the field of permeable brick production technology, and in particular to a reclaimed permeable brick batching device for sponge cities. Background Technology

[0002] Permeable bricks are a type of green and environmentally friendly building material. The raw materials are mainly environmentally friendly materials such as cement, sand, slag, and fly ash, formed under high pressure and not fired at high temperatures. The entire brick is compressed in one piece, without layering, resulting in a homogeneous brick with no layering. The surface is free of cracks and delamination; it has good wear resistance and does not peel off after extrusion, making it suitable for heavier load-bearing environments; it has good permeability and strong anti-slip properties; and its color is natural and long-lasting. Currently, existing mixers are mostly used to mix the proportioned materials during the preparation of permeable bricks.

[0003] For example, the recycled permeable brick batching device for sponge cities disclosed in Chinese patent literature (announcement number: CN216831592U) uses mechanical weighing to make the batching accurate, which solves the problem that existing raw material batching requires multiple repeated batchings due to manual batching.

[0004] However, the proportioned materials enter the mixing chamber all at once through the movable door. Due to the weight and fluidity of the materials, without an effective guidance and dispersion mechanism, they will directly accumulate at the bottom of the mixing chamber, forming a tightly packed material pile. When water is then supplied and mixed through the water pipe, the water is relatively concentrated, forming a water layer. The inside of the material pile, especially the bottom center, remains dry, and the material particles are hardly wetted by water. This seriously hinders the mixing process and greatly reduces the mixing efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for material mixing to result in layering and accumulation, which greatly reduces mixing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A recycling permeable brick batching device for sponge cities includes a batching and mixing tank. Two distributing cylinders are symmetrically arranged above the batching and mixing tank. The upper end of each distributing cylinder is connected to a batching hopper, and the lower end of each distributing cylinder is connected to the batching and mixing tank. A rotating rod is rotatably arranged inside each distributing cylinder. Several distributing plates extending radially outward along the rotating rod are fixedly connected to the rotating rod, and the several distributing plates are evenly distributed in a circular pattern. The rotating rods in the two distributing cylinders can be driven to rotate synchronously by a first driving mechanism.

[0008] A rotating sleeve is rotatably installed inside the mixing tank. A diversion pipe extends radially outward from the upper part of the rotating sleeve. Several nozzles are installed on the diversion pipe for spraying water onto the material surface. Several stirring rods extend radially outward from below the diversion pipe on the rotating sleeve. A spiral lifting plate is sleeved on the lower part of the rotating sleeve, and the spiral lifting plate is located below the stirring rods.

[0009] Preferably, the rotating sleeve is provided with two diversion pipes, which are symmetrically distributed.

[0010] Preferably, the nozzles are arranged in a linear array on the lower surface of the splitter tube.

[0011] Preferably, several stirring rods on the same horizontal plane are evenly distributed in a circular pattern and form a stirring unit, and the vertical projections of several stirring rods in two adjacent stirring units are staggered.

[0012] Preferably, each of the stirring units consists of three stirring rods.

[0013] Preferably, the end of the dispensing plate is in contact with the inner wall of the dispensing cylinder.

[0014] Preferably, the first drive mechanism includes a first servo motor, a synchronous pulley, and a synchronous belt. The first servo motor is connected to the rotating rod of one of the dispensing cylinders. Each of the two rotating rods is fitted with a synchronous pulley, and the two synchronous pulleys are connected by the synchronous belt.

[0015] Preferably, a water pump is fixedly installed at the upper end of the mixing tank. One end of the water pump is connected to an inlet pipe, and the other end of the water pump is connected to an outlet pipe. The outlet pipe is rotatably connected to the upper end of the rotating sleeve through a sealed bearing and is connected to the diversion pipe.

[0016] Preferably, the rotating sleeve is driven to rotate by a second driving mechanism, the second driving mechanism including a second servo motor and a worm gear, the output shaft of the second servo motor is fixedly mounted with a worm, the upper end of the rotating sleeve is sleeved with the worm gear, and the worm gear is meshed with the worm gear.

[0017] Preferably, the lower end of the mixing tank is connected to a discharge pipe, and a valve is installed on the discharge pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, materials from two batching hoppers are added to the batching mixing tank at a uniform speed, and water is evenly sprayed onto the surface of the materials by rotating the diversion pipe and cooperating with the nozzle. This avoids the materials from being tightly packed together, which would prevent the internal materials from being wetted by water, thereby improving the overall batching and mixing efficiency.

[0029] Example

[0030] like Figure 1-4 As shown, this utility model provides a technical solution: a batching device for recycled permeable bricks used in sponge cities, including a batching and mixing tank 1. The batching and mixing tank 1, as the core container of the entire batching process, is made of high-strength, corrosion-resistant stainless steel. Its tank body is cylindrical with thick and smooth walls, ensuring structural stability when containing various materials and facilitating subsequent cleaning and maintenance. Two distributing cylinders 2 are symmetrically arranged above the batching and mixing tank 1. The distributing cylinders 2 are also made of stainless steel and manufactured using professional welding processes. The material distribution cylinder 2 is securely connected to the mixing tank 1. It has a slender cylindrical shape, which lays the foundation for the initial diversion and uniform addition of materials. The upper end of the material distribution cylinder 2 is connected to the material hopper 22. The material hopper 22 is funnel-shaped with a wider top and a narrower bottom. The hopper opening is wide, which makes it convenient for operators to pour different kinds of materials. The inclination angle of the hopper wall is carefully designed so that the materials can fall smoothly into the material distribution cylinder 2 below, avoiding the phenomenon of material jamming and accumulation. The lower end of the material distribution cylinder 2 is connected to the mixing tank 1 to ensure that the materials after diversion can smoothly enter the mixing stage.

[0031] A rotating rod 23 is rotatably installed inside the dispensing cylinder 2. The rotating rod 23 is made of tough, non-deformable alloy steel and has been finely ground to achieve a smooth surface, reducing frictional resistance during rotation. Several dispensing plates 24 extending radially outward along the rotating rod 23 are fixedly connected to the rotating rod 23 and are evenly distributed circumferentially. The dispensing plates 24 are made of a flexible plastic material, and their ends are in close contact with the inner wall of the dispensing cylinder 2. This close-fitting design ensures that the material is fully divided within the dispensing cylinder 2, preventing leakage or accumulation in dead corners. When the rotating rod 23 rotates, the material is added sequentially and uniformly into the mixing tank 1. The rotating rods 23 in the two dispensing cylinders 2 can be driven to rotate synchronously by a first drive mechanism, which ensures the coordination and efficiency of the entire dispensing process.

[0032] The first drive mechanism includes a first servo motor 21, synchronous pulleys 25, and a synchronous belt 26. The first servo motor 21, as the power source, is a high-performance, high-precision motor product, mounted on a stable motor mount. The motor mount is tightly fixed to the bracket containing the dispensing cylinder 2 by bolts, ensuring that the motor will not shift or shake during operation. The first servo motor 21 is connected to the rotating rod 23 of one of the dispensing cylinders 2 via a high-strength coupling. When the first servo motor 21 starts, its output shaft can stably and accurately drive the connected rotating rod 23 to rotate. Each of the two rotating rods 23 is fitted with a synchronous pulley 25, which is made of high-quality rubber and metal. The hub is made of composite material. The rubber outer layer can ensure good friction and reliable transmission of the synchronous belt 26, while also reducing noise during transmission. The two synchronous pulleys 25 are connected by the synchronous belt 26. The synchronous belt 26 is made of high-strength, wear-resistant polyurethane material and has a steel wire reinforcement layer inside to ensure that it will not break or loosen during long-term, high-intensity transmission. This ensures that the two rotating rods 23 can rotate synchronously and stably, so as to add the material in the two batching hoppers 22 to the batching mixing tank 1 at a uniform speed, avoiding the accumulation of a large amount of material at the bottom of the batching mixing tank 1 at one time, and creating good initial conditions for subsequent mixing processes.

[0033] The first servo motor 21, as the core power drive component, is mounted on a specially designed shock-absorbing base. The shock-absorbing base adopts a rubber and spring composite structure to effectively absorb the vibration generated during motor operation, ensuring the smooth operation of the motor and thus ensuring the stability of the rotation of the rotating rod 23. The synchronous pulley 25 undergoes dynamic balancing testing before installation to ensure that there will be no eccentricity during high-speed rotation, which would affect the transmission effect of the synchronous belt 26. After installation, the synchronous belt 26 needs to be tensioned. Through a professional tensioning device, the tension is adjusted to the optimal state to ensure that it will not be too loose to cause slippage or too tight to cause increased wear during long-term use. This ensures that the two rotating rods 23 can rotate accurately and stably synchronously, providing a reliable guarantee for the uniform distribution of materials.

[0034] A rotating sleeve 3 is rotatably installed inside the mixing tank 1. A diversion pipe 31 extends radially outward from the upper part of the rotating sleeve 3. Several nozzles 32 are installed on the diversion pipe 31, which are used to spray water onto the material surface. In this embodiment, two diversion pipes 31 are installed on the rotating sleeve 3, and the two diversion pipes 31 are symmetrically distributed to ensure uniform wetting of the material. The diversion pipes 31 are made of corrosion-resistant aluminum alloy and are fixedly connected to the rotating sleeve 3 through a precise welding process to ensure that no leakage occurs when high-pressure water flows through. Their flat design ensures sufficient cross-section for water flow while reducing air resistance during rotation, which helps improve spraying stability.

[0035] The nozzles 32 are arranged in a linear array on the lower surface of the distributor pipe 31. Each nozzle 32 is a fine atomizing nozzle with an ingenious internal structure design. Through a special nozzle construction, it can disperse the water flow into tiny droplets. The nozzles 32 are made of stainless steel with a polished surface, making them not only corrosion-resistant but also less prone to clogging. This ensures that water can be smoothly sprayed onto the surface of the materials in the mixing tank 1, preventing the materials from clumping together and thus avoiding the situation where the materials cannot be properly wetted by water. This lays a solid foundation for the thorough mixing of materials and water.

[0036] Several stirring rods 33 extend radially outward from below the diversion pipe 31 on the rotating sleeve 3. A spiral lifting plate 34 is sleeved on the lower part of the rotating sleeve 3, located below the stirring rods 33. Several stirring rods 33 on the same horizontal plane are evenly distributed in a circle and form a stirring unit. The vertical projections of several stirring rods 33 in two adjacent stirring units are staggered. The stirring rods 33 are made of high-strength stainless steel with threaded protrusions on the surface, which can enhance the shear force on the material during stirring and increase the friction with the material, promoting rapid tumbling of the material. Each stirring unit consists of three stirring rods 33, with an included angle of 120 degrees between them, evenly distributed on the same circumference. They work together to better mix the material and water, ensuring the uniformity of the ingredients and improving the quality of the permeable bricks.

[0037] The end of the material distribution plate 24 contacts the inner wall of the material distribution cylinder 2. The end of the material distribution plate 24 is edged with soft rubber material, which not only ensures a tight fit with the inner wall of the material distribution cylinder 2 to prevent material leakage, but also avoids scratching damage to the inner wall of the material distribution cylinder 2 during high-speed rotation, thus extending the service life of the equipment. At the same time, it ensures that the material is accurately divided and conveyed at a uniform speed in the material distribution cylinder 2.

[0038] A water pump 38 is fixedly installed at the upper end of the mixing tank 1. The water pump 38 is a high-performance centrifugal pump. Its outer shell is made of corrosion-resistant engineering plastic, while the internal impeller is made of stainless steel, combining sturdiness and durability. One end of the water pump 38 is connected to an inlet pipe 39, which is made of flexible rubber tubing. This material characteristic allows it to be easily connected to different water sources and can effectively buffer the impact of water flow, ensuring the stability of water flow. The other end of the water pump 38 is connected to an outlet pipe 310, which is rotatably connected to the upper end of the rotating sleeve 3 through a sealed bearing. This connection method is ingeniously designed, ensuring a continuous and stable water supply even when the rotating sleeve 3 is rotating. At the same time, the outlet pipe 310 is connected to the diversion pipe 31, thereby stably delivering water to the sprinkler operation.

[0039] The rotation of the rotating sleeve 3 is driven by a second drive mechanism, which includes a second servo motor 36 and a worm gear 35. The output shaft of the second servo motor 36 is fixedly mounted with a worm 37. When the second servo motor 36 starts running, its output shaft drives the worm 37 to rotate. The worm gear 35 is sleeved on the upper end of the rotating sleeve 3, and the worm 37 and the worm gear 35 are meshed together. With the special spiral structure of the worm 37, the worm gear 35 is driven to rotate slowly and stably, thereby driving the rotating sleeve 3 to rotate as well, providing stable power support for subsequent mixing, watering and other operations.

[0040] Next, the lower end of the mixing tank 1 is connected to a discharge pipe 4. The discharge pipe 4 serves as the material discharge channel and is made of stainless steel. Its diameter is reasonably designed to ensure smooth material discharge and effectively control the flow rate. A valve 41 is installed on the discharge pipe 4. The valve 41 is a manual ball valve. This type of valve is simple and convenient to operate. After the material and water are fully mixed in the mixing tank 1, the operator can manually turn the valve 41 gently, and the mixed material will be smoothly discharged through the discharge pipe 4, providing a high-quality material base for the subsequent permeable brick molding process.

[0041] The working process of this utility model:

[0042] Step 1: Pour different types of materials into two batching hoppers 22 respectively. Start the first servo motor 21. The output shaft of the first servo motor 21 rotates, driving the connected rotating rod 23 to rotate through the coupling. Since the rotating rod 23 is externally fixedly sleeved with a synchronous wheel 25, and the two synchronous wheels 25 are connected by a synchronous belt 26, the other rotating rod 23 will also rotate synchronously. When the rotating rod 23 rotates, the distribution plate 24 will rotate inside the distribution cylinder 2. After the material falls from the batching hopper 22 into the distribution cylinder 2, the distribution plate 24 will evenly divide the material. As the distribution plate 24 rotates, the material is added to the batching mixing tank 1 at a uniform speed. In this way, the material in the two batching hoppers 22 is added to the batching mixing tank 1 at a uniform speed, avoiding the accumulation of a large amount of material at the bottom of the batching mixing tank 1 at one time.

[0043] Step 2: Start the second servo motor 36 and water pump 38. The output shaft of the second servo motor 36 drives the worm 37 to rotate. Since the outer surface of the worm 37 meshes with the tooth surface of the worm wheel 35, the rotation of the worm 37 will drive the worm wheel 35 to rotate, which in turn drives the rotating sleeve 3 to rotate. When the rotating sleeve 3 rotates, the diversion pipe 31 will rotate accordingly. By connecting the water inlet pipe 39 to an external water source, the water pump 38 draws water from the water inlet pipe 39 and then delivers it to the rotating sleeve 3 through the water outlet pipe 310. The water enters the diversion pipe 31 through the rotating sleeve 3 and is evenly sprayed on the surface of the material in the mixing tank 1 through the nozzle 32. This combination of the rotation of the diversion pipe 31 and the nozzle 32 allows the water to be evenly sprayed on the surface of the material, avoiding the material from being tightly packed and causing the internal material to be unable to be wetted by water.

[0044] Step 3: During the rotation of the rotating sleeve 3, the stirring rod 33 fixedly connected to its outside will also rotate, so that the material and water can be mixed better. In addition, when the spiral lifting plate 34 rotates, it will lift the material at the bottom of the mixing tank 1 upward, further promoting the mixing of the material from top to bottom and improving the mixing efficiency. When the material and water are fully mixed, the valve 41 outside the discharge pipe 4 is opened, and the mixed material will be discharged through the discharge pipe 4.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
