Description

Technical Field

[0001] This application relates to the technical field of sand and gravel separators, and in particular to a wet concrete sand and gravel separator with water-saving function. Background Technology

[0002] In the construction industry, wet concrete generates a large amount of waste during transportation and pouring, which contains recyclable resources such as sand and gravel. To achieve resource recycling and reduce environmental pollution, wet concrete sand and gravel separators have emerged. These separators can separate sand and gravel from waste wet concrete for reuse in concrete preparation and other processes. Currently, common wet concrete sand and gravel separators typically consist of a separation unit and a conveying structure. The separation unit contains screening and mixing components, which separate the sand and gravel from the wet concrete. The separated sand and gravel are discharged through their respective outlets. However, traditional wet concrete sand and gravel separators mostly use water for single-use washing of sand and gravel, discharging it directly after rinsing without dedicated collection and recycling devices. This results in significant water waste, increased operating costs, and failure to meet current environmental protection requirements. Furthermore, existing washing devices often use fixed-angle nozzles to wash the sand and gravel. Since sand and gravel move quickly during transport, the contact area and time with the washing water are small, making it difficult to thoroughly remove surface impurities such as cement slurry. This results in low purity of the separated sand and gravel, affecting its recycling and reuse. Utility Model Content To address the issues of poor rinsing performance and water waste in existing sand and gravel separators, this application provides a wet concrete sand and gravel separator with water-saving functionality.

[0003] The wet concrete sand and gravel separator with water-saving function provided in this application adopts the following technical solution: A water-saving wet concrete sand and gravel separator includes a main body, with a sand outlet and a stone outlet on the front end face of the main body. A water storage tank is installed in front of the main body, and a rotating seat is installed on the upper end face of the water storage tank. The rotating seat is rotatably connected to the water storage tank, and a first motor for driving the rotating seat to rotate is installed on the outer side of the water storage tank. A washing shell corresponding to the stone outlet is installed at the head of the rotating seat, and the lower end of the washing shell is rotatably connected to the rotating seat. An electric cylinder for driving the washing shell to flip is installed on the rotating seat. A flushing assembly corresponding to the washing shell is installed on the outer side of the water storage tank, and a filter screen is installed in the water storage tank.

[0004] By adopting the above technical solution, the sand and gravel separator achieves the separation and processing of wet concrete sand and gravel through its main body. After processing, the sand and gravel are discharged separately through the sand outlet and the stone outlet. The rotating seat, driven by a first motor, allows the washing shell to accurately align with the stone outlet to receive the separated stones. Simultaneously, an electric cylinder drives the washing shell to rotate, facilitating the discharge of the washed stones. The flushing assembly washes the stones inside the washing shell, improving the cleaning effect of the sand and gravel. Furthermore, a water tank collects the washing water, achieving water resource recycling and water conservation.

[0005] Optionally, the water storage tank includes a main tank shell and a positioning platform for rotating the rotating seat. The positioning platform is installed on the upper end of the inner side of the main tank shell and is fixedly connected to the main tank shell.

[0006] By adopting the above technical solution, the positioning platform provides stable rotation support for the rotating seat, ensuring that the rotating seat can rotate smoothly and guaranteeing the accuracy and stability of the washing shell in receiving and discharging stones.

[0007] Optionally, a discharge shell is installed on the rear end face of the main housing, and a discharge ramp is installed in the discharge shell, the discharge ramp being fixedly connected to the discharge shell.

[0008] By adopting the above technical solution, the setting of the unloading shell and the discharge ramp facilitates the discharge of the washed stones from the water storage tank. The inclined design of the discharge ramp helps the stones to slide down smoothly by their own weight, thus improving the unloading efficiency.

[0009] Optionally, the rotating seat includes a chassis and a disc base for rotatably mounting the washing material shell. The chassis is rotatably mounted in a positioning platform, and the disc base is vertically fixed to the upper end face of the chassis.

[0010] By adopting the above technical solution, the structural design of the chassis and the base makes the rotation of the rotating seat more stable. The chassis rotates in the positioning platform, and the base provides a support point for the installation and rotation of the washing shell, ensuring the normal operation of the washing shell.

[0011] Optionally, the washing shell includes a shell base and a top shell, the top shell being rotatably mounted on the upper end face of the shell base, and a second motor for driving the top shell to rotate being fixedly mounted on the lower end of the shell base.

[0012] By adopting the above technical solution, the washing shell adopts a structure of a base and a top shell, and the top shell can rotate under the drive of the second motor, which can make the stones roll fully inside the washing shell, increase the contact area between the stones and the rinsing water, and improve the cleaning effect.

[0013] Optionally, a cylinder seat and a connecting vertical plate are respectively provided on both sides of the lower end face of the housing. The cylinder seat and the connecting vertical plate are fixedly connected to the housing. The cylinder seat is rotatably connected to the output end of the electric cylinder, and the connecting vertical plate is rotatably installed on the head of the disc seat.

[0014] By adopting the above technical solution, the setting of the cylinder base and the connecting vertical plate enables the electric cylinder to smoothly drive the washing shell to rotate. The connecting vertical plate rotates at the head of the disc base, ensuring the flexibility and stability of the washing shell rotation and facilitating the discharge of stones.

[0015] Optionally, the top shell includes a sloping outer shell and a mesh plate, the mesh plate being installed at the bottom of the sloping outer shell and fixedly connected to the sloping outer shell.

[0016] By adopting the above technical solution, the inclined shell and mesh plate structure of the top shell can guide the flow direction of the rinsing water and stones, while the mesh plate can make the cleaning water flow out smoothly and prevent stones from falling, thus ensuring the smooth progress of the cleaning process.

[0017] Optionally, the flushing assembly includes a water pump, a water supply pipe assembly, and a flushing nozzle, wherein the water supply pipe assembly is connected to the outlet of the water pump, and the flushing nozzle is fixedly installed at the head of the water supply pipe assembly.

[0018] By adopting the above technical solution, the combination of the water pump, water supply pipe group and flushing nozzle of the flushing component can deliver water in the water storage tank to the flushing nozzle to perform high-pressure flushing of the stones in the washing shell, ensuring the cleaning effect.

[0019] In summary, this application includes at least one of the following beneficial technical effects: The water storage tank of this application can collect cleaning water, realizing the recycling of water resources and greatly reducing water waste. By recycling water resources, the operating cost of the equipment is reduced, while also meeting environmental protection requirements. The rotation of the rotating seat, the flipping of the washing shell, and the rotation of the top shell increase the contact area and contact time between the stones and the rinsing water, improving the cleaning effect. It can effectively remove impurities such as cement slurry from the surface of the stones, making the separated stones meet the standards for recycling and reuse. The electric cylinder-driven flipping of the washing shell, along with the design of the unloading shell and discharge ramp, makes the unloading of cleaned stones and the discharge of waste more convenient and faster, improving the working efficiency of the equipment.
