Description

Technical Field

[0001] This utility model belongs to the technical field of concrete conveying equipment, specifically relating to an automatic cleaning, recycling, and conveying structure for waste materials from concrete mixing plants. Background Technology

[0002] With the rapid development of infrastructure construction and the real estate industry in my country, the demand for concrete, as a core building material, continues to rise, driving the continuous expansion of the concrete mixing plant industry. However, mixing plants generate a large amount of waste during the production process, including wastewater from mixing tank cleaning, residual concrete residue, and scrap sand and gravel aggregates. If not handled properly, this will not only waste resources but also cause serious environmental problems. Therefore, it is necessary to design an automatic cleaning, recycling, and conveying structure for concrete mixing plant waste.

[0003] Existing concrete mixing plants often consume large amounts of fresh water for rinsing during the cleaning process of concrete waste. The wastewater after rinsing is directly discharged, which not only wastes water resources but also easily causes soil and water pollution. In addition, the directly discharged wastewater may contain sand, resulting in incomplete recycling and treatment of concrete waste in the later stages, leading to waste in the later treatment of concrete waste. Utility Model Content

[0008] As a further optimization of this utility model, the pressing assembly includes fixed plates at both ends of the top of the storage compartment away from the cover plate. A pressure roller is rotatably mounted on the top of the two fixed plates at their adjacent ends. A servo motor is fixedly mounted on one end of the front of one of the fixed plates. The output end of the servo motor passes through the fixed plate and is fixedly connected to the pressure roller.

[0009] As a further optimization of this utility model, the mortar conveying mechanism includes a mounting frame, rollers, a conveyor belt, a servo motor, and a support. There are two mounting frames, which are fixedly installed inside the storage chamber at both ends away from the cover plate and extend to the outside of the storage chamber. The support is fixedly installed at the bottom of the two mounting frames on the side away from the storage chamber.

[0010] As a further optimization of this utility model, the two rollers are rotatably installed on both sides inside the two mounting frames. The transmission belt is fitted around the outside of the two rollers and placed below the bottom of the pressure roller to cooperate with them. The servo motor three is fixedly installed on the front end of one mounting frame away from the storage compartment through a motor mounting frame, and the output end of the servo motor three is fixedly connected to a roller through the mounting frame.

[0012] As a further optimization of this utility model, a water pump is fixedly installed at the bottom of the rear of the storage compartment. The input end of the water pump is connected to the interior of the storage compartment, and the output end of the water pump is fixedly connected to a connecting pipe.

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, an automatic waste collection, recycling, and conveying structure for a concrete mixing plant includes a storage and circulation component 1 as its core support. The storage and circulation component 1 includes a storage bin 100, which serves as the core container for the initial collection and processing of waste. Its internal structure and external connecting components together constitute a complete waste processing flow. On one side of the top of the storage bin 100, a mortar conveying mechanism 6 extending to its exterior is installed. This mortar conveying mechanism 6 is responsible for separating and conveying the mortar moisture in the waste. Specifically, the mortar conveying mechanism 6 includes a mounting frame, rollers, a conveyor belt, a servo motor, and a support frame. Two mounting frames are provided, and both are fixedly installed on the storage bin. The brackets are fixedly installed on one side of both ends of the storage bin 100 and extend to the outside of the storage bin 100, providing stable support for the entire mortar conveying mechanism 6. The brackets are fixedly installed on the bottom of the two mounting frames away from the storage bin 100, further enhancing the load-bearing capacity and stability of the mounting frames. Two rollers are rotatably installed on both sides inside the two mounting frames. The conveyor belt is fitted around the outside of the two rollers. The servo motor 3 is fixedly installed on the front end of one mounting frame away from the storage bin 100 through the motor mounting frame. The output end of the servo motor 3 is fixedly connected to a roller through the mounting frame. When the servo motor 3 is started, it can drive the roller to rotate, thereby driving the conveyor belt to operate and realize the mortar conveying.

[0027] like Figure 1 , Figure 2 , Figure 3As shown, to facilitate the separation of mortar and water in conjunction with the mortar conveying mechanism 6, a pressing component 2 is installed on the top of the storage and circulation component 1, near the mortar conveying mechanism 6. The pressing component 2 cooperates with the mortar conveying mechanism 6. The pressing component 2 includes fixed plates 202 at both ends of the top of the storage bin 100 near the mortar conveying mechanism 6. A pressure roller 201 is rotatably mounted on the top of the two fixed plates 202 at their adjacent ends, and the pressure roller 201 is positioned above the conveyor belt inside the mortar conveying mechanism 6 (the specific space between the pressure roller 201 and the conveyor belt...). The gap height can be adjusted according to actual operation requirements. A servo motor 200 is fixedly installed on one end of the front of a fixed plate 202. The model of the servo motor 200 is ECM-E3M-C20807SSE. The output end of the servo motor 200 passes through the fixed plate 202 and is fixedly connected to the pressure roller 201. After the servo motor 200 is started, it can drive the pressure roller 201 to rotate. The pressure roller 201 cooperates with the conveyor belt to squeeze the mortar falling on the conveyor belt, so that the water in the mortar can penetrate through the mesh of the conveyor belt to the bottom, thereby realizing the liquid separation work.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cover plate 105 is fixedly installed on the other side of the top of the storage bin 100. A filter guide trough 3 is fixedly installed on the inner side of the cover plate 105, and the side of the filter guide trough 3 away from the cover plate 105 is positioned above and in contact with the conveyor belt inside the mortar conveying mechanism 106, so that the sand filtered by the filter guide trough 3 can fall directly onto the surface of the mortar conveyor 6 for conveying. A spiral conveying assembly 4, which is connected to the inside of the cover plate 105, is fixedly installed on the top of the cover plate 105 for conveying concrete waste. The spiral conveying assembly 4 includes a fixing frame 402 fixedly installed on the top of the outer side of the cover plate 105, and a fixed bracket is fixedly installed on the top of the inner side of the fixing frame 402. The bottom of the feeding hopper 401 is fixedly connected to the transfer hopper 400. A servo motor 403 is fixedly installed on the side of the transfer hopper 400 near the cover plate 105. The model of the servo motor 403 is ECM-E3L-C20401SSE. The output end of the servo motor 403 is fixedly installed with a spiral conveying blade 404 that extends into the interior of the transfer hopper 400 and fits against its inner side. When concrete waste enters the feeding hopper 401, it will fall into the transfer hopper 400. When the servo motor 403 starts, it drives the spiral conveying blade 404 to rotate, which can push the concrete waste in the transfer hopper 400 to move away from the storage hopper 100.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, to achieve water resource recycling and cleaning and recycling of concrete waste inside the spiral conveyor assembly 4, a water pump 102 is fixedly installed at the bottom rear of the storage chamber 100. The input end of the water pump 102 is connected to the inside of the storage chamber 100, and can draw clean water from the storage chamber 100. The output end of the water pump 102 is fixedly connected to a connecting pipe 103. A drain pipe 104 is fixedly installed on the top of the conveyor 400 near the cover plate 105. The inside of the drain pipe 104 is connected to the end of the connecting pipe 103 away from the water pump 102. The bottom of the drain pipe 104 is fixedly connected to multiple nozzles 106 placed on the top of the inner side of the conveyor 400. When it is necessary to clean the inside of the conveyor 400 or to rinse the concrete waste, the water pump 102 is started, and clean water flows through the connecting pipe 103. The water enters the drain pipe 104 and is then sprayed into the transmission chamber 400 through the nozzle 106 to achieve cleaning and rinsing functions. At the same time, the rinsed water can flow back into the storage chamber 100 for recycling. A connecting pipe is installed on the bottom of the transmission chamber 400 near the cover plate 105, and the bottom of the connecting pipe is fixedly connected to the inner top of the cover plate 105. A filter screen is fixedly installed on the inner top of the connecting pipe to filter the gravel in the concrete waste, which facilitates the conveying of the gravel by the screw conveyor blade 404. A discharge port is opened on the bottom of the transmission chamber 400 away from the drain pipe for easy discharge of waste. The transmission chamber 400 is designed with an inclination to facilitate the return and collection of cleaning water and to control the water content of the waste inside the transmission chamber 400.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, simultaneously, on the side of the spiral conveying assembly 4 away from the storage and circulation assembly 1, a crushed stone conveying mechanism 5 is fixedly installed below it. The spiral conveying assembly 4 and the crushed stone conveying mechanism 5 cooperate to receive and convey the crushed stone waste conveyed by the spiral conveying assembly 4. The crushed stone conveying mechanism 5 includes a support frame, conveying rollers, a conveyor belt, and a servo motor. There are two support frames and two conveying rollers. The two support frames are placed on the bottom of the conveying chamber 400 on the side away from the storage chamber 100. The two conveying rollers are rotatably installed on both sides inside the two support frames. The conveyor belt is fitted around the outside of the two conveying rollers and placed in the conveying chamber 400. At the bottom, servo motor four is fixedly mounted on the front end of a support frame via a motor mounting bracket. The output end of servo motor four is fixedly connected to a transmission roller via the support frame. When the spiral transmission assembly 4 conveys the crushed stone waste to the end of the transmission bin 400 away from the storage bin 100 and it falls, it will fall onto the transmission belt. Servo motor four starts to drive the transmission roller to rotate, thereby driving the transmission belt to run and convey the crushed stone waste to the designated recycling position. L-shaped support rods are fixedly installed on the top of the two support frames near the side of the transmission bin 400. The top of the two L-shaped support rods at the end closest to each other is fixedly connected to the outside of the transmission bin 400.

[0031] It should be noted that in this automatic cleaning, recycling, and conveying structure for concrete batching plant waste, the waste generated by the concrete batching plant is first conveyed into the feed hopper 401. A servo motor 403 drives a spiral conveyor blade 404 to transport the concrete waste within the conveying hopper 400. Simultaneously, a water pump 102 draws clean water from the storage hopper 100, which is then sprayed through a connecting pipe 103 and a drain pipe 104, finally reaching the inside of the conveying hopper 400 through a nozzle 106 to wash and clean the concrete waste. The washed mortar can be separated from the aggregate by a filter screen in the connecting pipe. The mortar then enters the cover plate 105 through the connecting pipe, and then the sand and water are separated by a filter guide trough 3. The inclined design of the filter guide trough 103 facilitates the subsequent filtration of sand during circulation. The sand rolls off the surface of the filter guide trough 103 and falls onto the conveyor belt of the mortar conveying mechanism 6. The mortar conveying mechanism 6 then transports the sand and controls its water content. Later, the servo motor 200 drives the pressure roller 201 to rotate, working with the mortar conveying mechanism 6 to press and dewater the sand, ensuring efficient dewatering. After dewatering, the sand is conveyed to a designated location by the mortar conveying mechanism 6. Meanwhile, the crushed stone, cleaned inside the conveying chamber 400, is conveyed by the spiral conveyor blade 404 and falls onto the conveyor belt of the crushed stone conveying mechanism 5. Finally, the crushed stone is conveyed by the crushed stone conveying mechanism 5. Through these steps, cleaning and water recycling can be achieved. The entire process is highly automated, enabling efficient cleaning, sorting, recycling, and conveying of waste materials.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
