Technical Field

[0001] The present application relates to the technical field of industrial solid waste utilization, and in particular to a solid waste treatment device for utilizing solid waste as a resource. Background Art

[0002] Solid waste, also known as industrial solid waste, refers to the solid waste generated during industrial production activities. Solid waste typically refers to various waste residues, dust, and other wastes discharged into the environment during industrial production, such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, coal cinder, sulfuric acid residue, waste gypsum, desulfurization ash, carbide slag, and salt mud. If these wastes cannot be promptly treated, treatment agents are often added to the solid waste to reduce land occupation and environmental pollution, thereby enabling waste utilization. These treatment agents are then used to modify the solid waste, transforming it into industrially viable, environmentally friendly building materials, as described in patents CN110282941A and CN117443895B.

[0003] To ensure the performance of the modified product, the solid waste and treatment agent must be uniformly mixed in a specific ratio, usually by weight. However, existing solid waste treatment processes and the devices used in them do not provide an equipment structure for controlling the mixing of solid waste and treatment agent to achieve the target weight ratio.

DETAILED DESCRIPTION

[0015] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0016] In addition, numerous specific details are provided in the detailed description below to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0017] The present application provides a solid waste treatment device for resource utilization of solid waste, which is used to mix solid waste and a treatment agent in proportion, including a solid waste conveying device 200, a first treatment agent supplying device 300, a first conveying device 310 and an agitator 500.

[0018] The input end of the solid waste conveying device 200 is adapted to be connected to the output end of the solid waste supply device, and the output end of the solid waste conveying device 200 is connected to the input end of the agitator 500. The solid waste conveying device 200 uses a belt scale to convey the solid waste into the agitator 500 and to weigh the conveyed solid waste during the conveying process.

[0019] A first conveying device 310 is provided at the output end of the first treatment agent supply device 300. The input end of the first conveying device 310 is connected to the output end of the first treatment agent supply device 300. The output end of the first conveying device 310 is connected to the input end of the agitator 500. The first conveying device 310 uses a weighing screw conveyor to convey the treatment agent into the agitator 500 and weigh the weight of the conveyed treatment agent during the conveying process.

[0020] The agitator 500 is adapted to agitate and mix the solid waste and the treatment agent, and output the mixed solid waste and treatment agent mixture through its output end.

[0021] This application utilizes a solid waste conveyor 200 and a first conveyor 310 to convey solid waste and treatment agent into the blender 500, and measures the weight of the conveyed solid waste during the conveying process. The weight values ​​obtained determine the opening and closing of the solid waste conveyor 200, thereby precisely controlling the weight of the solid waste introduced into the blender 500. Similarly, the weight of the treatment agent introduced into the blender 500 can also be controlled by the weighing results of the first conveyor 310 and the opening and closing of the conveying equipment.

[0022] This application does not make any specific limitation on the method for controlling the weight value of the input material of the solid waste treatment device for resource utilization of solid waste, as long as it can achieve the addition of treatment agent and solid waste according to the target ratio and the uniform mixing of treatment agent and solid waste in proportion. The speed of solid waste input into the agitator 500 can be changed by changing the rotation speed of the driving device (variable frequency motor) of the belt scale, thereby changing the weight of solid waste input per unit time; the speed of treatment agent input can be changed by changing the rotation speed of the driving device (variable frequency motor) of the weighing screw conveyor, thereby adjusting the weight ratio of solid waste and treatment agent input into the agitator 500 per unit time. The weighing result of the conveying equipment can also be used to realize the opening and closing of the equipment, thereby accurately controlling the weight ratio of the two.

[0023] In addition, solid waste in the form of slag, blocks, or granules will not cause dust during transportation, so equipment such as belt scales can be used. However, some treatment agents are in powder form. If they are weighed and transported using equipment such as belt scales, the dust will be high during transportation, creating an unfriendly working environment for personnel, causing unnecessary material waste, and also posing a certain risk. This application uses a weighing screw conveyor, which uses its relatively closed transmission cavity to separate the powdered treatment agent from the external environment and directly transport it to the closed mixing chamber of the agitator 500, which has a certain dust-proof effect.

[0024] In one possible implementation, the staff calculates the weight of the treatment agent required to treat the target weight of solid waste according to the target weight ratio and the actual processing volume required for production. After the solid waste conveying device 200 detects that the material it is conveying has reached the target value, the solid waste conveying device 200 is shut down, the continuous conveying is stopped, and the addition of solid waste (into the agitator 500) is terminated; after the first conveying device 310 detects that the material it is conveying has reached the target value, the first conveying device 310 is shut down, and the addition of the treatment agent into the agitator 500 is stopped.

[0025] Compared with existing solid waste treatment devices, the present application can control the input weight of solid waste and treatment agent by weighing the weight of the transmitted material, thereby meeting the weight ratio requirements of solid waste and treatment agent of the existing process, and can control the mixing of solid waste and treatment agent according to the target weight ratio.

[0026] This application does not limit the specific structure of the belt scale, which is a weighing belt conveyor device, as long as it can achieve belt transportation and weighing of transported materials. Please refer to patent documents CN108613722B and CN111664921B.

[0027] In one possible implementation, a solid waste treatment device for resource utilization also includes a screening device 100, preferably a vibrating screening device, to reduce the chance of material blocking the screen, preventing otherwise qualified material from passing through. The input of the screening device 100 is adapted to connect to the output of a solid waste supply device, which in turn connects to the input of a solid waste conveyor 200. The aperture of the screening device 100 is set based on the state of the solid waste and the desired treatment effect. The screening device 100 is used to screen out hard materials such as larger stones, bricks, and tiles, thereby preventing damage to the agitator 500 at the rear end and extending its service life. Furthermore, the material output from the screening device 100 is relatively uniform, allowing the solid waste to fall onto the belt scale at a relatively uniform rate. Furthermore, the solid waste treatment device for resource utilization also includes a crushing device, preferably a grinding device, such as a mill, to wet-grind and crush sticky solid waste, reducing the particle size of the solid waste and ensuring effective mixing and treatment. The crushing device's input is connected to the solid waste supply device's output, which in turn is connected to the input of the screening device 100. The screening device 100 outputs the screened material (solid waste) from its output. Solid waste trapped on the screen surface can be removed and fed back into the crushing device for crushing, followed by further screening and sieving until the material passes the screening.

[0028] In a possible implementation, there are more than two first treatment agent supply devices 300 , and the two or more first treatment agent supply devices 300 are connected to the input end of the agitator 500 through the first conveying device 310 at the output end thereof.

[0029] In a possible implementation, the conveying drive device of the belt scale adopts a variable frequency motor, and the conveying speed of the belt scale is changed by adjusting the rotation speed of the variable frequency motor.

[0030] In one possible implementation, the agitator 500 is a planetary mixer. Furthermore, the agitator 500 is a wheel-type planetary mixer. It should be noted that this application does not limit the specific structure of the wheel-type planetary mixer; as long as the wheel and agitator can uniformly mix the solid waste and the treatment agent to ensure a good mixing effect, it is sufficient. For details, please refer to patent documents CN206733316U and CN2562861Y.

[0031] In one possible implementation, a wheel-rolling planetary mixer is provided with a circular barrel-shaped mixing kettle. The grinding wheel and the stirring paddle rotate in the sealed circular barrel. The grinding wheel can crush and mix the sticky solid waste material with the treatment agent to fully blend the two materials. The materials are then stirred and mixed by the planetary stirring paddle. The crushing and mixing of the grinding wheel and the stirring and mixing of the planetary stirring teeth are alternated and reciprocated, which can quickly mix them evenly. An opening is provided at the bottom of the circular barrel (the axial output end), and a valve (preferably a normally open valve) is provided at the opening. The opening of the valve can be adjusted by air pressure or oil pressure to control the opening and closing state of the opening, so that the material can be output from the output end of the opening at a certain speed or the material can be retained in the sealed stirring chamber for stirring.

[0032] In one possible implementation, a heating device and a temperature sensor are provided in the stirring chamber of the agitator 500. The heating device is preferably a heating wire, and the heating rate is adjusted by changing the current flowing therein. After the temperature sensor detects that the temperature in the stirring chamber has reached the standard, the conveying device is started and the material is added for stirring. Under the premise of ensuring that the sensing end of the temperature sensor is located in the stirring chamber, the sensing end of the temperature sensor can be as far away from the heating device as possible. For example, the heating wire is laid on the inner wall of the stirring tank of the planetary mixer, and the temperature sensor is installed on the shaft at the center of the axis of the tank body.

[0033] In addition, the present application does not make a specific limitation on the number of agitators 500. Depending on the mixing effect of the solid waste and the treatment agent, the number of agitators 500 can be increased as appropriate. In one possible implementation, there are more than two agitators 500, and the two or more agitators 500 are distributed in sequence and connected head-to-tail (input end). Along the conveying track of the material in the two or more agitators 500 connected head-to-tail, the input end of the agitator 500 close to the feed end is respectively connected to the output ends of the solid waste conveying device 200, the first conveying device 310, and the second conveying device 410. The output end of the agitator 500 close to the discharge end is connected to the input end of the discharge conveying device 700.

[0034] This application does not make any specific restrictions on the connection structure and discharge power at the head and tail connection of two adjacent agitators 500. They can be connected through a connecting pipe equipped with a drive pump, or a transfer drive device 600 for transferring materials can be added. If the solid waste conveying device 200, the first conveying device 310 and the second conveying device 410 are not long enough to be directly transferred to the input end of the agitator 500 due to the optional belt transport length and the device installation occasion, a transfer drive device for transferring materials can also be added in the middle. Figure 1 As shown, the transfer driving device 600 can adopt a belt conveyor.

[0035] For some non-powdered treatment agents, such as granular treatment agents, a weighing screw conveyor can be used to transport and weigh the treatment agents, or a belt scale can be used. In one possible implementation, the solid waste treatment device for resource utilization of solid waste also includes a second treatment agent supply device 400; the output end of the second treatment agent supply device 400 is provided with a second conveying device 410, the input end of the second conveying device 410 is connected to the output end of the second treatment agent supply device 400, and the output end of the second conveying device 410 is connected to the input end of the agitator 500, and the second conveying device 410 uses a belt scale.

[0036] This application does not make any specific restrictions on the number of the first treatment agent supply device 300, the first conveying device 310, the second treatment agent supply device 400, and the second conveying device 410. Each first treatment agent supply device 300 is configured with at least one first conveying device 310, and each second treatment agent supply device 400 is configured with at least one second conveying device 410, to ensure that the treatment agent is added as much as possible and that the solid waste treatment work is not restricted due to a shortage of conveying devices. This application also does not make any specific restrictions on the type, state, or name of the treatment agent supplied by each supply device. Multiple supply devices can be loaded with the same treatment agent, or there can be only one supply device for each treatment agent, as long as the total weight of the treatment agent added to the agitator 500 meets the requirements for the weight ratio of the solid waste treatment agent in the process.

[0037] In a possible implementation, the number of first processing agent supply devices 300 and first conveying devices 310 is the same and arranged in a one-to-one correspondence, and the number of second processing agent supply devices 400 and second conveying devices 410 is the same and arranged in a one-to-one correspondence.

[0038] In one possible implementation, the solid waste treatment device for recycling solid waste also includes a discharge conveyor 700; the input end of the discharge conveyor 700 is connected to the output end of the agitator 500, and the output end of the discharge conveyor 700 is provided with a discharge device 710. Furthermore, the discharge conveyor 700 adopts a belt conveyor, and the discharge device 710 adopts a belt conveyor discharge trolley. The discharge trolley carrying bin of the belt conveyor discharge trolley is provided with a height detection device, which uses a proximity switch or the like to detect whether there is material piled up at this height. After the material accumulation height exceeds the detection position of the height detection device, the discharge program is started, for example, automatically switching to the left or right side for discharge, and the forward or backward direction of the material distribution trolley can also be automatically switched.

[0039] In one possible implementation, the first treatment agent supply device 300 includes a silo and a hopper. The silo has a discharge port. The hopper's input is connected to the silo's discharge port, and the hopper's output is connected to the input of the first conveyor 310 to deliver the treatment agent to the first conveyor 310. Furthermore, the hopper itself is funnel-shaped, i.e., an inverted frustum-shaped pipe with two axial openings: the thicker end serves as the hopper's input, and the thinner end serves as the hopper's output. The hopper is preferably a conical hopper.

[0040] In one possible implementation, a star-shaped discharger is provided at the output of the first treatment agent supply device 300. The input of the star-shaped discharger (the feed end of the discharger) is connected to the output of the first treatment agent supply device 300, and the output of the star-shaped discharger (the discharge end of the discharger) is connected to the input of a weighing screw conveyor. The star-shaped discharger is a quantitative feeding device used in conjunction with the weighing screw conveyor to quantitatively output and weigh the discharged material (treatment agent). This dually controls and confirms the weight of the treatment agent introduced into the agitator 500, precisely controlling and ensuring that the weight ratio of solid waste to treatment agent meets the target value.

[0041] The present application also provides a current detection device to detect the current of all electrical equipment in the solid waste treatment device for resource utilization of solid waste. By monitoring the current changes of all components, the fault is determined. When a component fails, the faulty component and the components at the front end of the process are automatically powered off and stopped, while the components at the back end of the process continue to operate to prevent blockage and material waste, while protecting the production line from the spread of faults. In addition, the present application also provides a monitoring device. The various components of the solid waste treatment device for resource utilization of solid waste, including but not limited to the screening device 100, the solid waste conveying device 200, the first treatment agent supply device 300, the first conveying device 310, the second treatment agent supply device 400, the second conveying device 410, the agitator 500, the discharge conveying device 700, the unloading device 710, etc., are all located within the camera area of ​​the monitoring device. Surveillance cameras are installed on each component and in areas requiring focused observation. This application also adds a controller 800 with its own display screen 810. The output of the monitoring equipment is electrically connected to the input of the controller 800, and the monitoring screen is connected to the display screen 810 of the controller 800, allowing real-time monitoring via the large screen. Furthermore, the various components of the aforementioned solid waste treatment device for resource utilization of solid waste, including but not limited to the screening device 100, the solid waste conveying device 200, the first treatment agent supply device 300, the first conveying device 310, the second treatment agent supply device 400, the second conveying device 410, the agitator 500, the discharge conveying device 700, the unloading device 710, etc., all have their control terminals, such as the switch control and the speed control terminal of the variable frequency motor, electrically connected to the controller 800.
