Description

Technical Field

[0001] The invention relates to the technical field of environmental monitoring, and in particular to an industrial solid waste property identification and sampling device. Background Art

[0002] Industrial solid waste refers to solid waste generated in industrial production activities. One type of solid waste, referred to as industrial waste, is various waste residues, dust and other wastes discharged into the environment during industrial production. It can be divided into general industrial waste (such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, coal slag, sulfuric acid residue, waste gypsum, salt mud, etc.) and industrial hazardous solid waste.

[0003] With the continuous development and progress of industrialization in today's society, more and more industrial solid waste is generated. In order to protect the natural environment, industrial solid waste needs to be sampled in the factory after it is generated, and then the properties are identified in the testing center. At the same time, some industrial waste residues that have been landfilled also need to be sampled on the spot and returned to the testing center for testing to detect the content of components in the soil, so as to achieve the detection of environmental quality and prevent the landfilled industrial solid waste from damaging the environment.

[0004] The routine on-site sampling of industrial solid waste is that workers put on protective clothing and manually shovel or dig industrial solid waste samples to achieve the purpose of sampling and collection of industrial solid waste. However, a large amount of industrial solid waste piled up in the factory area and buried underground will clump after a certain period of time, making manual shoveling or digging very inconvenient. It is especially inconvenient when it is necessary to collect samples of industrial solid waste at different depths.

[0005] In addition, if the inspectors stay in the industrial solid waste area for too long, it will be harmful to their health. Especially before the property test is completed and the composition of the industrial solid waste is not reasonably characterized, there are certain safety hazards if they stay in the industrial solid waste area for a long time for sampling.

[0006] The conventional sampling process requires the cooperation of two to three inspectors, generally one or two inspectors dig or shovel industrial solid waste samples, and the other inspector holds the sample bag to store the industrial solid waste, which is inconvenient. In summary, the present application provides an industrial solid waste attribute identification sampling device. Summary of the invention

[0021] A sleeve for closing the third hole is inserted in the tube core, the top of the sleeve passes through the tube core and is fixed to the sampling tube, and a fourth hole is opened on the sleeve, which connects the third hole located in the same sampling cavity as the first hole with the diversion cavity.

[0022] Furthermore, a guide plate is provided in the sampling chamber, the top end of which is connected to the barrel core and located above the third hole, and the bottom end of which is inclined outward and extends into the sampling tube.

[0034] 5. By setting the cone head and the tube core under the action of the adjusting screw rod, the cone head is used to block the suction hole on the drill bit during the drilling process, and after drilling into the predetermined depth, the cone head opens the suction hole by moving upward. It has the effect of preventing industrial waste above the predetermined depth from entering the suction air duct during drilling. At the same time, it also has the effect of improving the stability of the inner tube and the drill bit through the tube core.

[0035] 6. After the industrial solid waste samples are extracted, sample collection can be realized simultaneously, which has the advantage of being able to meet the needs of single-person operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Please refer to Figures 1 to 9 As shown, the industrial solid waste property identification sampling device provided by the present invention includes an outer tube 1, a spiral blade 2, an inner tube 3, a drill bit 4, a suction pump 5, a sample collector 7, a motor 8, a transmission switching assembly 10, crushing teeth 11 and a suction hole 12.

[0047] The outer tube 1 and the inner tube 3 are both hollow, and the spiral blades 2 are arranged on the outer surface of the outer tube 1. When the outer tube 1 rotates, the spiral blades 2 are driven to rotate to play the role of drilling into industrial solid waste. Then, the drilling method is used to replace the manual insertion method of industrial solid waste in the prior art, which is more labor-saving and easy to operate.

[0048] The inner tube 3 is inserted into the outer tube 1, and its top and bottom ends are both extended from the outer tube 1, so that the outer tube 1 is rotatably arranged outside the inner tube 3. Specifically, the surface of the inner tube 3 is provided with an outwardly convex annular structure, and the inner wall surface of the outer tube 1 is provided with an annular groove corresponding to the annular structure. The cooperation of the annular structure and the annular groove is used to realize the rotation cooperation of the outer tube 1 and the inner tube 3 in the circumferential direction, and the outer tube 1 and the inner tube 3 are limited in the axial direction.

[0049] The suction pump 5 is mounted on the bracket 9. The suction pump 5 has a suction air duct, and the front end of the suction air duct is a head air inlet pipe 6. The air inlet end of the head air inlet pipe 6 is rotatably matched with the top end of the inner tube 3. After the suction pump 5 is running, the suction air duct is used to form a negative pressure in the inner tube 3. At the same time, the head air inlet pipe 6 is used to rotate with the inner tube 3, so that the inner tube 3 can keep rotating while the suction pump 5 is running.

[0050] The drill bit 4 is a cone-shaped structure as a whole, and its interior is set as a hollow structure, and the cavity of the drill bit 4 is connected with the inner cavity of the inner tube 3. The inner cavity of the inner tube 3 and the cavity of the drill bit 4 are located upstream of the head air inlet pipe 6 to form a part of the suction air duct. When the inner tube 3 rotates, the drill bit 4 is driven to rotate synchronously. The surface of the drill bit 4 is provided with evenly distributed crushing teeth 11 and suction holes 12. When the drill bit 4 rotates, the crushing teeth 11 are used to grind and crush the industrial solid waste, and the crushed industrial solid waste residue is sucked into the suction air duct from the suction hole 12 under the action of negative pressure and moves in the suction air duct.

[0051] The sample collector 7 is arranged on the suction air duct of the suction pump 5. Specifically, the sample collector 7 is mounted on a bracket 9, which is located between the head air inlet pipe 6 and the suction pump 5. The sucked industrial solid waste passes through the sample collector 7 when moving in the suction air duct and is collected by the sample collector 7.

[0052] The motor 8 is mounted on the bracket 9, and the bracket 9 is equipped with a pipe sleeve 13, which is rotatably sleeved on the inner tube 3, and then the inner tube 3 is mounted on the bracket 9 through the pipe sleeve 13. Preferably, the present application distributes the suction pump 5 and the motor 8 on both sides of the inner tube 3. This makes the industrial solid waste attribute identification sampling device more balanced as a whole and more convenient to use.

[0053] The inner tube 3 and the outer tube 1 are both connected to the output end of the motor 8 through the transmission switching component 10. The transmission switching component 10 enables the motor 8 to have the following three states:

[0054] The first state: the outer tube 1 is driven alone to rotate and drill into the industrial solid waste;

[0055] The second state: the inner tube 3 is driven alone to drive the drill bit 4 to rotate and crush industrial solid waste;

[0056] The third state---the outer tube 1 and the inner tube 3 are driven to rotate at the same time to achieve the effect of crushing industrial solid waste while drilling into it.

[0057] Further, the transmission switching assembly 10 includes a pulley component 10 - 1 , a driving ring plate 10 - 2 , a driven ring plate 10 - 3 and a connecting bolt 10 - 4 ;

[0058] The driving wheel 10-1a and the driven wheel 10-1b of the pulley component 10-1 are respectively mounted on the output shaft of the motor 8 and the inner tube 3, a driving ring plate 10-2 is provided on both end surfaces of the driven wheel 10-1b, a driven ring plate 10-3 is provided on the outer tube 1 and the inner tube 3, and the driving ring plate 10-2 is located between the two driven ring plates 10-3. The driving ring plate 10-2 and the driven ring plate 10-3 located on the same side of the driven wheel 10-1b are connected in a detachable state through connecting bolts 10-4.

[0059] By connecting the driven ring plate 10-3 on the outer tube 1 with one of the driving ring plates 10-2 using the connecting bolts 10-4, the transmission switching assembly 10 can be placed in the first state; by connecting the driven ring plate 10-3 on the inner tube 3 with one of the driving plates using the connecting bolts 10-4, the transmission switching assembly 10 can be placed in the second state; by connecting the two driven ring plates 10-3 to the two driving ring plates 10-2 at the same time using the connecting bolts 10-4, the transmission switching assembly 10 can be placed in the third state.

[0060] In this way, the transmission switching assembly 10 can be switched between the above three states by operating the connecting bolt 10 - 4 when the motor 8 is stopped.

[0061] Furthermore, the suction air duct also includes a rear air inlet pipe 14 , which is directly connected to the air inlet end of the suction pump 5 , and the sample collector 7 is arranged between the front air inlet pipe 6 and the rear air inlet pipe 14 .

[0062] Furthermore, the sample collector 7 includes a sampling barrel 7-1, a barrel core 7-2, a sampling cavity 7-3 and a sampling tube 7-4. The sampling barrel 7-1 is a structure with a closed top and an open bottom, and the top of the sampling barrel 7-1 is fixedly connected to the lower surface of the bracket 9, so that the sampling barrel 7-1 is in an inverted state with the open end facing downward.

[0063] The barrel core 7-2 is arranged at the center of the sampling barrel 7-1, and the top surface of the barrel core 7-2 contacts the inner top wall of the sampling barrel 7-1, and the top surface of the barrel core 7-2 is rotatably connected to the inner top wall of the sampling barrel 7-1. The side surface of the barrel core 7-2 includes a first arc-shaped flow guide surface and a second flow guide surface extending vertically downward from the bottom of the first flow guide surface from top to bottom, so that the circumferential surface of the barrel core 7-2 axially located on the first flow guide surface is an arc-shaped concave structure converging from outside to inside from top to bottom, and the circumferential surface of the barrel core 7-2 axially located on the second flow guide surface is a circumferential structure.

[0064] There are multiple sampling cavities 7-3 and sampling tubes 7-4 corresponding to each other, and they are centrally symmetrically distributed in the barrel core 7-2, so that when the barrel core 7-2 rotates in the sampling barrel 7-1, the sampling cavities 7-3 and the sampling tubes 7-4 can move synchronously.

[0065] The surface of the sampling tube 7-1 is provided with a first hole 7-5 connected to the tail end of the head air inlet pipe 6 at the top corresponding to the side of one of the sampling cavities 7-3. The tail end of the head air inlet pipe 6 is installed in the first hole 7-5, so that the inner cavity of the sampling tube 7-1 is connected to the head air inlet pipe 6. The side of the tube core 7-2 is provided with a second hole 7-6 adapted to the first hole 7-5 corresponding to each sampling cavity 7-3, and one of the second holes 7-6 is always kept aligned and matched with the first hole 7-5, so that there is always a sampling cavity 7-3 connected to the head air inlet pipe 6. By rotating the tube core 7-2, the second holes 7-6 of different sampling cavities 7-3 are aligned with the first hole 7-5 respectively, so as to achieve the effect of switching the sampling cavity 7-3 to collect industrial solid waste samples.

[0066] The inner center of the cylinder core 7-2 is provided with a guide cavity 7-7 whose top end is connected to the front end of the tail air inlet pipe 14. The guide cavity 7-7 is connected to the suction pump 5 through the tail air inlet pipe 14 to form a part of the suction air duct. The cylinder core 7-2 is provided with a third hole 7-8 located above the sampling tube 7-4 and connected to the guide cavity 7-7 corresponding to each sampling cavity 7-3, and the first hole 7-5 and the second hole 7-6 are both located above the sampling tube 7-4. At this time, the head air inlet pipe 6, the first hole 7-5, the second hole 7-6, the sampling cavity 7-3, the third hole 7-8, the guide cavity 7-7 and the tail air inlet pipe 14 form a suction air duct.

[0067] The core 7-2 is plugged with a sleeve 7-9 for closing the third hole 7-8. The top of the sleeve 7-9 passes through the core 7-2 and is fixed to the sampling tube 7-1. The sleeve 7-9 and the core 7-2 are rotated and matched, and a fourth hole 7-10 is provided on the sleeve 7-9. The fourth hole 7-10 connects the third hole in the same sampling cavity 7-3 as the first hole 7-5 with the guide cavity 7-7. At this time, when the third hole 7-8 corresponding to one of the sampling cavities 7-3 is aligned with the fourth hole 7-10, the third holes 7-8 corresponding to other sampling cavities 7-3 are closed by the sleeve 7-9 to ensure that the formed suction air duct corresponds to one of the sampling cavities 7-3, so that industrial solid waste can be collected into one of the sampling cavities 7-3 at the same time. At the same time, by rotating the core 7-2 to align the third holes 7-8 corresponding to different sampling cavities 7-3 with the fourth holes 7-10, the sampling cavity 7-3 and the sampling tube 7-4 can be switched in time. To facilitate sampling of industrial solid waste at different depths.

[0068] Furthermore, a guide plate 15 is provided in the sampling cavity 7-3, the top end of which is connected to the cylinder core 7-2 and is located above the third hole 7-8, and the bottom end of which is inclined outward and extends into the sampling tube 7-4. The bottom end of the guide plate 15 is located below the first hole 7-5, the second hole 7-6, the third hole 7-8 and the fourth hole 7-10 in the height direction, and the bottom end of the guide plate 15 extends to the middle of the sampling tube 7-4 in the radial direction of the corresponding sampling tube 7-4. The circumference of the portion of the guide plate 15 located above the sampling tube 7-4 is in contact with the cylinder core 7-2, and the top end surface of the sampling tube 7-4 is in contact with the bottom of the portion of the guide plate 15 located above the sampling tube 7-4. The guide plate 15 is located between the second hole 7-6 and the third hole 7-8 in the inside and outside direction of the sampling cavity 7-3, so that the airflow bypasses the bottom of the guide plate 15 from the bottom after entering the sampling tube 7-4 and then rises into the third hole 7-8. And by utilizing this process, industrial solid waste can be better dropped into the sampling tube 7-4 and collected.

[0069] Furthermore, the bottom of the core 7-2 and the bottom of the sampling tube 7-4 are located in the same plane and extend outside the sampling tube 7-1. The bottom end of the sampling cavity 7-3 passes through the bottom of the core 7-2. The bottom of the core 7-2 is threadedly installed with a pad 16 supported on the bottom of the sampling tube 7-4. The pad 16 extends circumferentially to the bottom of the sampling tube 7-4 to support the sampling tube 7-4. At the same time, by removing the pad 16 from the bottom of the core 7-2, the sampling tube 7-4 can be taken out of the sampling tube 7-1.

[0070] The outer diameter of the top end of the drill bit 4 is set to be greater than or equal to the outer diameter of the outer tube 1, and the top end of the drill bit 4 is rotatably matched with the bottom end of the outer tube 1. By connecting the top end of the drill bit 4 with the bottom end of the outer tube 1 and rotatably matching, the drill bit 4, the outer tube 1 and the inner tube 3 form a relatively fixed whole in the axial direction, which can improve the overall stability in the process of drilling into industrial solid waste or crushing industrial solid waste.

[0071] Furthermore, the inner cavity of the drill bit 4 is provided with a cone head 17 which is conical and closes the suction port from the inner opening of the suction hole 12, the diameter of the larger end of the cone head 17 is smaller than the inner diameter of the inner tube 3, and the top end of the cone head 17 is fixed with a tube core 18 whose outer diameter is smaller than the inner diameter of the inner tube 3;

[0072] The head air inlet pipe 6 extends upward from the top of the inner tube 3 to form an arc portion with a central angle of 90°. The top of the tube core 18 is rotatably mounted with an adjusting screw 19. The top of the adjusting screw 19 passes through the outside of the arc portion and is threadedly matched with the arc portion. The part of the adjusting screw 19 located outside the arc portion is threadedly connected with a locking nut 20 that abuts against the surface of the arc portion. The height of the cone head 17 can be adjusted by rotating the adjusting screw 19 using the tube core 18. When the cone head 17 is separated from the inner wall surface of the drill bit 4 by moving upward, the suction hole 12 is opened, and a gap is formed between the cone head 17 and the inner wall surface of the drill bit 4. The gap forms a part of the suction air duct for industrial solid waste to be sucked through the inner cavity of the inner tube 3. Similarly, by rotating the adjusting screw 19 so that the cone head 17 contacts the inner wall surface of the drill bit 4, the suction air can be closed. In addition, by adjusting the screw rod 19 and the locking nut 20 in conjunction with the tube core 18 and the cone head 17, when the cone head 17 abuts against the inner wall surface of the drill bit 4, the stability of the drill bit 4 can be improved, thereby improving the stability of the entire device.

[0073] The above are only preferred embodiments of the present invention and are 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 in the protection scope of the present invention.
