Description

Technical Field

[0001] This invention relates to the field of waste detection technology, specifically a separation device for solid waste detection and its usage method. Background Technology

[0002] Solid waste generally refers to solid and semi-solid waste generated by humans in daily life, production, construction, and other activities that cannot be utilized at a certain time and place and is discarded, polluting the environment. This includes solid particles separated from exhaust gases, garbage, slag, broken utensils, and sludge, etc., which are collectively referred to as solid waste. It also includes solid particles separated from wastewater and exhaust gases. All solid or semi-solid substances generated by all human activities that no longer have use value to their owners and are discarded are collectively called solid waste. Solid waste generated from various production activities is commonly called waste residue; solid waste generated from daily life activities is called garbage. The term "solid waste" actually only refers to the original owner.

[0003] With the improvement of urban residents' living standards, the output of urban solid waste has increased significantly, and the contradiction between urban garbage and land occupation has become increasingly prominent. More and more urban garbage, mining waste, industrial waste and other materials are encroaching on more and more land, which not only hinders urban environmental sanitation and causes environmental pollution, but also buries a large number of green plants and destroys the ecological balance of the natural environment.

[0004] However, in any production or daily life process, owners often only utilize certain effective components of raw materials, commodities, or consumer goods. Most solid waste, which no longer has any use value for its original owner, still contains components needed by other production industries. Through certain technical processes, it can be transformed into raw materials for relevant departments or industries, or even used directly. Therefore, the concept of solid waste is relative and changes with time and space.

[0005] However, due to the diverse sources and types of solid waste, it is necessary to test it before recycling. Unlike ores, solid waste contains numerous elements in varying amounts. To detect the types and amounts of different elements in different components of solid waste, multiple tests are required. Therefore, to shorten the testing process, preliminary separation of the elemental components in solid waste is necessary before testing, thereby reducing the testing time. However, existing separation methods, such as magnetic suction or air sieves, cannot accurately separate the components in solid waste, resulting in poor separation performance and errors in component detection using existing solid waste testing equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a separation device for solid waste detection to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A separation device for solid waste detection includes a heating box, a heating tube fixedly connected inside the heating box, a lifting frame fixedly connected to the inner wall of the heating box, a slot provided in the lifting frame, a fixing rod provided in the slot, a separation box fixedly connected to the fixing rod, and a metal guide rod fixedly connected to the inner wall of the heating box between the separation box and the heating tube, with a coil wound on the outer wall of the metal guide rod.

[0009] As a further aspect of the present invention, a metal cage is provided on the outer wall of the heating tube.

[0010] As a further aspect of the present invention: heat-conducting fins are fixedly connected to the outer wall of the separation box.

[0011] As a further aspect of the present invention: a water inlet is provided on one side of the heating box, and a second control valve is connected to the water inlet; a water outlet is provided on the other side of the heating box, and a first control valve is connected to the water outlet.

[0012] As a further aspect of the present invention: the heating box, support frame, fixing rod, separation box, and heat-conducting fins are made of non-metallic materials.

[0013] As a further aspect of the present invention: a method of using a separation device for solid waste detection, comprising the following steps:

[0014] Step 1: The operator crushes the solid waste and performs micro-screening;

[0015] Step 2: The operator injects pure water into the heating box and the separation box, and heats the pure water through the heating tube. After the pure water temperature is heated to 95 degrees Celsius, agar and strong electrolyte are added to the separation box, so that the agar and strong electrolyte are completely dissolved in the water in the separation box, thereby forming a strong electrolyte solution in the separation box.

[0016] Step 3: Add the micro-sieved solid waste particles into the separation box, and simultaneously connect the coil to AC power. At this time, the metal rod is magnetized under the action of the coil, and a magnetic field is formed around the magnetized metal rod. At the same time, the charge in the coil is constantly changing due to the AC power in the coil, and an electric field is formed around the coil. At this time, the solid waste particles use a strong electrolyte solution as the separation medium. Based on the differences in density, specific magnetic susceptibility and conductivity between the particles, the particles of different components are separated.

[0017] Step 4: After separation, the heating tube stops heating and cold water is immediately injected into the heating chamber. At this time, the strong electrolyte solution cools down rapidly, and the agar in the electrolyte solution forms a gel after the temperature drops to 40 degrees Celsius.

[0018] Step 5: Cut the solidified agar gel into thin slices of different components according to the requirements of the test;

[0019] Step 6: When testing the specific elemental composition of solid waste particles in agar gels of different components, the agar gel can be reheated to 95 degrees Celsius, and then the solid waste particles in the agar gel can be filtered out through a sieving device for accurate testing.

[0020] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention first crushes and screens solid waste, and then separates solid waste particles of different components in the solid waste through magnetohydrodynamic separation. Compared with traditional screening methods, the separation effect between different components is clearer and better. At the same time, the solid waste particles are coagulated and sealed by the property of agar melting at high temperature and solidifying into a gel at room temperature. Then, the separated solid waste particles can be screened by slicing the gel-like agar. When detecting the specific elemental composition of solid waste particles in different components of agar gel, the agar gel can be heated again until the agar melts, and then the solid waste particles in the agar gel can be filtered out by screening equipment for accurate detection. The operation is simple and convenient, and it does not cause mixing of solid waste particles of different components, thus improving the accuracy of component detection. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] See Figures 1-5 In this embodiment of the invention, a separation device for solid waste detection includes a heating box 1, a heating pipe 6 fixedly connected inside the heating box 1, a lifting frame 2 fixedly connected to the inner wall of the heating box 1, a slot 3 provided in the lifting frame 2, a fixing rod 4 provided in the slot 3, and a separation box 5 fixedly connected to the fixing rod 4. A metal guide rod 8 fixedly connected to the inner wall of the heating box 1 is provided between the separation box 5 and the heating pipe 6. A coil 9 is wound around the outer wall of the metal guide rod 8. The invention first heats the water in the heating box 1 through the heating pipe 6, and then heats the water in the separation box 5 through the heated water, thereby achieving water-isolated heating of the strong electrolyte solution in the separation box 5, avoiding the boiling of the strong electrolyte solution, and thus reducing the impact of bubbles generated when the strong electrolyte solution boils on the separation of solid waste particles. At the same time, when the coil 9 is connected to AC power, the metal guide rod 8 is magnetically energized under the action of the coil 9. The magnetized metal rod 8 forms a magnetic field around it, while the alternating current in the coil 9 causes continuous changes in charge, creating an electric field around it. Solid waste particles are separated using a strong electrolyte solution as the separation medium, based on differences in density, specific magnetic susceptibility, and conductivity. After separation, the heating tube 6 stops heating, and cold water is immediately injected into the heating chamber 1, rapidly cooling the strong electrolyte solution. When the agar cools to 40 degrees Celsius, it forms a gel. The solidified agar gel is then cut into thin slices of different components according to the testing requirements. To detect the specific elemental composition of the solid waste particles within the agar gel, it can be reheated to 95 degrees Celsius and then filtered out using a sieving device for accurate detection.

[0029] In one instance of this embodiment, please refer to Figures 1-5A metal cage 7 is provided on the outer wall of the heating tube 6. The present invention forms a Faraday cage outside the heating tube 6 by setting the metal cage 7, and then isolates the electromagnetic field generated around the heating tube 6 through the electrostatic shielding effect of the Faraday cage, thereby eliminating the influence of the heating tube 6 on the electric field and magnetic field generated by the metal rod and coil 9 in the present invention.

[0030] In one instance of this embodiment, please refer to Figures 1-5 The outer wall of the separation box 5 is fixedly connected with heat-conducting fins 14. The present invention uses the heat-conducting fins 14 to control the heating and cooling rate of the strong electrolyte solution in the separation box 5.

[0031] In one instance of this embodiment, please refer to Figures 1-5 The heating box 1 has a water inlet 12 on one side, and a second control valve 13 is connected to the water inlet 12. The heating box 1 has a water outlet 10 on the other side, and a first control valve 11 is connected to the water outlet 10.

[0032] In one instance of this embodiment, please refer to Figures 1-5 The heating box 1, the lifting frame 2, the fixing rod 4, the separation box 5, and the heat-conducting fins 14 are made of non-metallic materials. The present invention avoids the influence of electromagnetic induction on the separation effect of the present invention by setting non-metallic materials.

[0033] In one instance of this embodiment, please refer to Figures 1-5 A method of using a separation device for solid waste detection includes the following steps:

[0034] Step 1: Operators crush and micro-sieve the solid waste to process the solid waste sample into particles of the same size for subsequent separation;

[0035] Step 2: The operator injects pure water into heating box 1 and separation box 5, and heats the pure water through heating pipe 6. After the pure water temperature is heated to 95 degrees Celsius, agar and strong electrolyte are added to separation box 5 so that the agar and strong electrolyte are completely dissolved in the water in separation box 5, thereby forming a strong electrolyte solution in separation box 5.

[0036] Step 3: Add the micro-sieved solid waste particles into the separation box 5, and simultaneously connect the coil 9 to the alternating current. At this time, the metal rod 8 is magnetized under the action of the coil 9, and a magnetic field is formed around the magnetized metal rod 8. At the same time, the charge in the coil 9 changes continuously due to the alternating current in the coil 9, and an electric field is formed around the coil 9. At this time, the solid waste particles use a strong electrolyte solution as the separation medium, and the particles of different components are separated according to the differences in density, specific magnetic susceptibility and conductivity between the particles.

[0037] Step 4: After separation, heating tube 6 stops heating and immediately injects cold water into heating box 1. At this time, the strong electrolyte solution cools down rapidly, and the agar in the electrolyte solution forms a gel after the temperature drops to 40 degrees Celsius.

[0038] Step 5: Cut the solidified agar gel into thin slices of different components according to the needs of the test. At this time, because the agar has solidified, all the separated solid waste particles are encapsulated inside the agar and no longer move, so they can be cut and separated arbitrarily.

[0039] Step 6: When testing the specific elemental composition of solid waste particles in agar gels of different components, the agar gel can be reheated to 95 degrees Celsius. At this point, the agar will melt into a liquid again. The solid waste particles in the agar gel can then be filtered out using a sieving device for accurate testing.

[0040] The working principle of this invention is as follows: First, the operator crushes and micro-sieves the solid waste. Second, the operator injects pure water into the heating tank 1 and the separation tank 5, and heats the pure water in the heating tank 1 through the heating pipe 6. This heated water then heats the water in the separation tank 5, thus achieving water-isolated heating of the strong electrolyte solution in the separation tank 5. This avoids boiling of the strong electrolyte solution, thereby reducing the impact of bubbles generated during boiling on the separation of solid waste particles. Simultaneously, the invention utilizes the metal cage 7... A Faraday cage is formed outside the heating tube 6, thereby isolating the electromagnetic field generated around the heating tube 6 through the electrostatic shielding effect of the Faraday cage, thus eliminating the influence of the heating tube 6 on the electric and magnetic fields generated by the metal rod and coil 9 in this invention. After the pure water temperature is heated to 95 degrees Celsius, agar and strong electrolyte are added to the separation tank 5, so that the agar and strong electrolyte are completely dissolved in the water in the separation tank 5, thereby forming a strong electrolyte solution in the separation tank 5; the third step: the micro-sieved solid waste particles are added to the separation tank 5, and at the same time, the coil 9 is connected to AC power. At this time, the metal rod 8 is in the coil 9 Magnetization occurs under the influence of the magnetized metal rod 8, which in turn creates a magnetic field around the rod. Simultaneously, the alternating current within the coil 9 causes continuous changes in charge, creating an electric field around it. At this point, solid waste particles are separated using a strong electrolyte solution as the separation medium, based on differences in density, specific magnetization, and conductivity. Fourth step: After separation, the heating tube 6 stops heating, and cold water is immediately injected into the heating chamber 1. The strong electrolyte solution rapidly cools down, while the agar, after reaching 40 degrees Celsius, undergoes electrolysis. Step 5: The solidified agar gel in the solution forms a gel; Step 6: The solidified agar gel is cut into thin slices of different components according to the needs of the test; At this time, because the agar is solidified, all the separated solid waste particles are covered inside the agar under the action of the agar and no longer move, so they can be cut and separated at will. Step 7: When the specific composition elements of the solid waste particles in the agar gel of different components are detected, the agar gel can be heated to 95 degrees Celsius again. At this time, the agar melts into a liquid again when heated, and then the solid waste particles in the agar gel are filtered out by the sieving equipment, so that accurate detection can be performed.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
