Description

Technical Field

[0001] This invention relates to the field of airflow pulverizing equipment technology, and specifically to an airflow pulverizing equipment for heavy metal capture agents. Background Technology

[0002] Heavy metal scavengers are chemical agents mainly used in wastewater treatment. When added to wastewater, they can separate and remove heavy metal ions from the wastewater. According to their main components, heavy metal scavengers are divided into two main categories: inorganic salts and organic compounds.

[0003] To facilitate mixing with wastewater, most solid heavy metal scavengers are processed into solid particles and powders during production, such as sodium sulfide and polyaluminum chloride. This process requires the use of air jet milling equipment, such as the air jet mill for producing heavy metal scavengers disclosed in the prior art, CN208427186U.

[0004] Existing air jet milling equipment has multiple high-pressure nozzles inside. The high-pressure air jet impacts large solid particles, and these solid particles collide with each other, thereby crushing the solid particles. For example, an air jet mill for producing heavy metal capture agents is disclosed in CN213762191U.

[0005] However, this pulverization method has the following two problems: First, the number of nozzles is limited and their positions are fixed, and there is no airflow covering the gap between two adjacent nozzles, which makes the impact range of the high-pressure airflow insufficient; Second, including heavy metal capture agents, most of the solid particles that need to be pulverized are not hard enough, and relying solely on the collision between these solid particles results in insufficient collision intensity, affecting the pulverization efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a heavy metal capture agent airflow pulverizing device, in which airflow also covers the gap between two adjacent nozzles, increasing the coverage and impact range of the airflow, and thus making the solid particles more uniformly stressed and improving the pulverizing effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A heavy metal capturing agent airflow pulverizing device, comprising a lower tank, a detachable upper tank at the top of the lower tank, a jet assembly inside the lower tank, and a toggle assembly for driving the jet assembly to rotate on one side of the lower tank.

A gasket that contacts the inner wall of the lower tank is fixedly arranged at the outer end of the annular air passage. Sliding grooves are provided on both sides of the lower tank, and the two sliding grooves are symmetrical. The gasket seals the sliding grooves. An extended protrusion is fixedly arranged on one side of the annular air passage. One end of the extended protrusion extends to the outside of the lower tank through the sliding groove on the corresponding side. The actuating component can actuate the extended protrusion, thereby driving the entire jet assembly.

One end of the air inlet pipe extends to the outside of the lower tank through another sliding groove. A return spring is provided at the top of the air inlet pipe. The top of the return spring is fixedly connected to the outer end of the lower tank. Multiple sets of positioning plates are provided on the inner wall of the lower tank by bolts. Each set of positioning plates consists of two plates. The two positioning plates in the same set sandwich the annular air passage in the middle. Two ball bearings that contact the annular air passage are fixedly provided on the side of the positioning plate facing the annular air passage.

[0010] Furthermore, the actuation assembly includes an actuation motor bolted to one side of the lower tank body. The bottom end of the output shaft of the actuation motor is fixedly provided with an actuation wheel. Two actuation rollers are provided on the outer side of the actuation wheel.

During the rotation, the actuation rollers can contact the extended protrusions.

[0011] Furthermore, a recycling pipe with a valve is fixedly provided at the bottom of the lower tank. A collection assembly is provided at the bottom of the recycling pipe. The collection assembly includes an outer collection box fixedly provided at the bottom of the recycling pipe. An inner collection box that can be removed separately is provided inside the outer collection box. Heavy metal capture agent particles that are not fully crushed fall downward into the inner collection box. Multiple magnetic rods are fixedly provided on the inner wall of the inner collection box. A sealing door is provided on one side of the outer collection box via a hinge.

[0012] Furthermore, a maintenance platform is fixedly provided on the front side of the lower tank body, two support legs are fixedly provided at the bottom of the maintenance platform, and a front ladder is fixedly provided on the front side of the maintenance platform.

[0013] The upper tank is equipped with a detachable mounting bracket on its inner wall. Multiple electromagnets are fixed at the bottom of the mounting bracket, and the electromagnets become magnetic when energized.

[0014] Furthermore, the top of the upper tank is provided with a separation assembly, the separation assembly including an upper flow channel provided at the top of the upper tank via a flange, the upper flow channel communicating with the interior of the upper tank, a separation box fixedly provided at the top of the upper flow channel, and a grading wheel provided inside the separation box;

[0015] A top motor for driving the grading wheel to rotate is fixedly installed on the rear side of the separation box. A discharge channel is fixedly installed on the front side of the separation box. The front end of the grading wheel is rotatably connected to the discharge channel. A box cover is provided on the top of the separation box, which closes the opening at the top of the separation box. Both ends of the box cover are connected to the upper tank body by bolts.

[0016] Furthermore, the lower tank is equipped with a feed pipe located above the jet assembly. Solid particles falling from the front end of the feed pipe fall to the center of the inner side of the annular air passage. The rear end of the feed pipe extends to the rear side of the lower tank, where a raw material storage tank and a conveying and mixing assembly are located.

[0017] The raw material storage tank is fixedly equipped with rear ladders on both sides, and a support frame is fixedly equipped at the bottom of the raw material storage tank. The conveying and mixing assembly includes a conveying channel located inside the raw material storage tank. The top of the conveying channel extends to the top of the raw material storage tank, and the bottom of the conveying channel is fixedly connected to the bottom of the inside of the raw material storage tank. An isolation plate is fixedly equipped on the inner wall of the raw material storage tank, and the conveying channel is embedded in the isolation plate. The isolation plate divides the inside of the raw material storage tank into two storage chambers, which respectively store iron particles and untreated heavy metal capture agent particles. Feeding pipes are fixedly equipped on both sides of the raw material storage tank, and the two feeding pipes are respectively connected to the two storage chambers. The feeding pipes are in a closed state during the crushing process.

[0018] Furthermore, the top of the raw material storage tank is provided with an inclined tube, the rear end of which is fixedly connected to the conveying channel and communicates with the conveying channel. The front end of the inclined tube is connected to the rear end of the feed pipe through a flange. The conveying channel has inlet ports on both sides, and the two inlet ports communicate with the two storage chambers respectively.

[0019] Furthermore, a central shaft is rotatably connected to the inner wall of the conveying channel, a conveying motor for driving the central shaft to rotate is fixed at the top of the conveying channel, and multiple spiral blades are fixed at the outer end of the central shaft.

[0020] A set of stirring rods is provided between two adjacent spiral blades. There are four stirring rods in a set, and the number of stirring rods in each set can be adjusted. The stirring rods are fixed at the outer end of the central shaft. After the stirring rods rotate, they play a role in stirring and mixing.

[0021] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0022] 1. By toggling the component, the jet assembly rotates and swings continuously. During the swing, the direction and position of the airflow ejected from the nozzles change continuously, so that the gap between two adjacent nozzles is also covered by airflow, increasing the coverage and impact range of the airflow. As a result, the solid particles are subjected to more uniform force, thus improving the crushing effect.

[0023] 2. By adding iron particles to the untreated heavy metal scavenging agent particles, the heavy metal scavenging agent particles can collide with the hard iron particles under the action of airflow, thereby increasing the collision intensity of the heavy metal scavenging agent particles, enabling them to be broken more thoroughly and increasing the crushing efficiency.

Detailed Implementation

[0043] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides, for example Figure 1-14 The heavy metal capture agent airflow pulverizing device shown includes a lower tank 1, a detachable upper tank 2 at the top of the lower tank 1, a jet assembly 12 inside the lower tank 1, and a toggle assembly 5 on one side of the lower tank 1 for driving the jet assembly 12 to rotate.

[0045] The jet assembly 12 includes an annular air passage 1201. Multiple nozzles 1203 are fixedly arranged inside the annular air passage 1201. A gasket 1204 is fixedly arranged at the outer end of the annular air passage 1201, which contacts the inner wall of the lower tank 1. Sliding grooves 13 are opened on both sides of the lower tank 1. The two sliding grooves 13 are symmetrical. The gasket 1204 seals the sliding grooves 13. An extended protrusion 1202 is fixedly arranged on one side of the annular air passage 1201. The extended protrusion 1202 passes through the gasket 1204. One end of the extended protrusion 1202 extends to the outside of the lower tank 1 through the sliding groove 13 on the corresponding side. The actuating component 5 can actuate the extended protrusion 1202, thereby causing the jet assembly 12 to rotate as a whole.

[0046] An inlet pipe 1205 for conveying high-pressure carbon dioxide gas is fixedly provided on the side opposite to the annular air passage 1201 and the extended protrusion 1202. The inlet pipe 1205 passes through the gasket 1204 and communicates with the inner cavity of the annular air passage 1201. One end of the inlet pipe 1205 extends to the outside of the lower tank 1 through another sliding groove 13. A return spring 1206 is provided at the top of the inlet pipe 1205. The top of the return spring 1206 is fixedly connected to the outer end of the lower tank 1. Multiple sets of positioning plates 15 are provided on the inner wall of the lower tank 1 by bolts. There are two positioning plates 15 in each set. The two positioning plates 15 in the same set clamp the annular air passage 1201 in the middle. Two balls 16 that contact the annular air passage 1201 are fixedly provided on the side of the positioning plate 15 facing the annular air passage 1201. The positioning plate 15 can clamp and fix the annular air passage 1201, and the balls 16 can reduce friction and ensure the smooth rotation of the annular air passage 1201.

[0047] High-pressure carbon dioxide gas is introduced into the annular air passage 1201 through the air inlet pipe 1205 and finally ejected outward through the nozzle 1203. The heavy metal scavenging agent that enters the lower tank 1 falls to the center of the inner side of the annular air passage 1201 and is thus impacted by the airflow ejected from the nozzle 1203. The heavy metal scavenging agent is in the form of solid particles. Under the action of the airflow, the solid particles collide with each other, and the impact force and collision force of the airflow further break the solid particles.

[0048] During the gas pulverization process, the actuating component 5 starts working and actuates the extended protrusion 1202. After being actuated, the extended protrusion 1202 slides along the sliding groove 13 and drives the jet assembly 12 to rotate at a certain angle. The nozzle 1203 thus swings left and right. During the swinging process, the direction and position of the airflow ejected by the nozzle 1203 change continuously, thereby continuously adjusting the force direction of the solid particles. This allows the airflow to cover the gap between two adjacent nozzles 1203, increasing the coverage and impact range of the airflow. As a result, the force on the solid particles becomes more uniform, improving the pulverization effect.

[0049] In order to continuously rotate the jet assembly 12, such as Figure 4-7 As shown, the actuating assembly 5 includes an actuating motor 501 bolted to one side of the lower tank body 1. An actuating wheel 502 is fixedly mounted at the bottom of the output shaft of the actuating motor 501. Two actuating rollers 504 are provided on the outer side of the actuating wheel 502. The two actuating rollers 504 are centrally symmetrically distributed around the center of the actuating wheel 502. Both ends of the actuating rollers 504 are rotatably connected to clamps 503. The clamps 503 are bolted to the outer end of the actuating wheel 502. The actuating wheel 502 can drive the actuating rollers 504 to rotate around the center of the actuating wheel 502. During the rotation, the actuating rollers 504 can contact the extended protrusion 1202.

[0050] When the jet assembly 12 is rotated, the actuating motor 501 is turned on and drives the actuating wheel 502 to rotate. The actuating roller 504 installed at the outer end of the actuating wheel 502 rotates under the drive of the actuating wheel 502 and comes into contact with the extended protrusion 1202. In the process of rotation, the extended protrusion 1202 is moved. The actuating roller 504 itself can rotate, thereby avoiding sliding friction during the contact with the extended protrusion 1202 and reducing wear during operation.

[0051] During the process of the roller 504 actuating the extended protrusion 1202, the extended protrusion 1202 will drive the annular air passage 1201 to rotate, which in turn will drive the air intake pipe 1205 to slide along another sliding groove 13. The sliding of the air intake pipe 1205 will cause the return spring 1206 to be stretched. As the actuating wheel 502 rotates, the roller 504 will separate from the extended protrusion 1202. At this time, the elastic force of the return spring 1206 will be released, pulling the air intake pipe 1205 and driving the jet assembly 12 to rotate as a whole, so that the jet assembly 12 returns to its original position. The elastic coefficient of the return spring 1206 does not need to be too large, as long as it can pull the jet assembly 12 to rotate. The two rollers 504 will alternately and repeatedly actuate the jet assembly 12 as the actuating wheel 502 rotates, and repeat the above process continuously. According to the actual measurement, the interval between each actuation is 1 second, and the jet assembly 12 takes 0.5 seconds to return to its original position each time it rotates.

[0052] The heavy metal scavenging agent is continuously transported into the lower tank 1 for crushing and processing, such as... Figure 1 , 2 As shown in Figures 3, 12, and 13, the lower tank 1 is provided with a feed pipe 11, which is located above the jet assembly 12. Solid particles falling from the front end of the feed pipe 11 fall to the inner center of the annular air passage 1201. The rear end of the feed pipe 11 extends to the rear side of the lower tank 1. The rear side of the lower tank 1 is provided with a raw material storage tank 6 and a conveying and mixing assembly 7.

[0053] The raw material storage tank 6 is fixedly equipped with rear ladders on both sides, and a support frame is fixedly equipped at the bottom of the raw material storage tank 6. The conveying and mixing assembly 7 includes a conveying channel 702 located inside the raw material storage tank 6. The top end of the conveying channel 702 extends to the top of the raw material storage tank 6, and the bottom end of the conveying channel 702 is fixedly connected to the bottom of the inside of the raw material storage tank 6. An isolation plate 601 is fixedly equipped on the inner wall of the raw material storage tank 6, and the conveying channel 702 is embedded in the isolation plate 601. The isolation plate 601 divides the inside of the raw material storage tank 6 into two storage chambers, which respectively store iron particles and untreated heavy metal capture agent particles. Feeding pipes are fixedly equipped on both sides of the raw material storage tank 6, and the two feeding pipes are respectively connected to the two storage chambers. The feeding pipes are in a closed state during the crushing process.

[0054] Two storage chambers store iron particles and untreated heavy metal scavenging agent particles, respectively. Both types of particles are transported upwards through conveyor channel 702, then along inclined pipe 701 to feed pipe 11, and finally fed into lower tank 1 through feed pipe 11. The iron particles are hard and are not crushed inside lower tank 1 (the heavy metal scavenging agent particles are crushed). Instead, iron particles are mixed with heavy metal scavenging agent particles. Under the action of airflow, the various particles collide with each other, thus increasing the collision intensity of heavy metal scavenging agent particles and enabling them to be crushed more thoroughly, thereby increasing the crushing efficiency. The reason for using carbon dioxide gas as the crushing gas is to create an oxygen-free environment inside lower tank 1, avoiding sparks generated by collisions between iron particles, and thus preventing dust explosions caused by sparks.

[0055] Iron particles and heavy metal scavenging agent particles need to be mixed evenly, such as Figure 12 As shown, the top of the raw material storage tank 6 is equipped with an inclined tube 701. The rear end of the inclined tube 701 is fixedly connected to the conveying channel 702, and the inclined tube 701 communicates with the conveying channel 702. The front end of the inclined tube 701 is connected to the rear end of the feed pipe 11 through a flange. Inlet ports 707 are provided on both sides of the conveying channel 702, and the two inlet ports 707 communicate with two storage chambers respectively. Separating the iron particles and the raw material, and then feeding them through the two inlet ports, ensures that the mixing ratio of the two is approximately equal and more uniform. Since the two types of particles flow during the feeding process, without the separation plate 601, either the raw material or the iron particles would flow into both inlet ports.

[0056] A central shaft 704 is rotatably connected to the inner wall of the conveying channel 702. A conveying motor 703 for driving the central shaft 704 to rotate is fixedly installed at the top of the conveying channel 702. Multiple spiral blades 705 are fixedly installed at the outer end of the central shaft 704. The spiral blades 705 perform the function of conveying after rotating. A set of stirring rods 706 is provided between two adjacent spiral blades 705. The number of stirring rods 706 in a set is four, but the number of stirring rods 706 in each set can be adjusted. The stirring rods 706 are fixed at the outer end of the central shaft 704. The stirring rods 706 stir and mix after rotating.

[0057] During the conveying of heavy metal scavenging agent particles and iron particles, since the bottom of the raw material storage tank 6 is sloping, the two types of particles can converge at the conveying channel 702 and enter the conveying channel 702 through the inlet 707. At this time, the central shaft 704 of the conveying motor 703 rotates, and the spiral blades 705 at the outer end of the central shaft 704 rotate and transport the solid particles in the conveying channel 702 upward along the conveying channel 702. During the upward movement of the two types of particles, they pass through each set of stirring rods 706, which play a role in stirring and mixing, so that the two types of particles are mixed evenly and finally fed into the lower tank 1. The even mixing is conducive to the uniform crushing of heavy metal scavenging agent particles.

[0058] Heavy metal scavenging agent particles that are not fully pulverized need to be recycled for secondary treatment, such as... Figure 1 , 8 As shown, a recovery pipe 9 with a valve is fixedly provided at the bottom of the lower tank 1. The jet assembly 12 works intermittently. The valve on the recovery pipe 9 will only open during the interval when the jet assembly 12 stops operating. A collection assembly 8 is provided at the bottom of the recovery pipe 9. The collection assembly 8 includes an outer collection box 801 fixedly provided at the bottom of the recovery pipe 9. An inner collection box 802 that can be removed separately is provided inside the outer collection box 801. Heavy metal capture agent particles that are not fully crushed fall downward into the inner collection box 802. Multiple magnetic rods 803 are fixedly provided on the inner wall of the inner collection box 802. A sealing door is provided on one side of the outer collection box 801 through a hinge.

[0059] Iron particles and incompletely crushed heavy metal scavenging agent particles fall under gravity and through the recycling pipe 9 into the outer collection box 801, eventually entering the inner collection box 802 for collection. They are then concentrated for further crushing. The magnetic rod 803 can attract the iron particles mixed in under magnetic force, thereby recovering the iron particles and enabling their reuse.

[0060] For ease of maintenance, such as Figure 1 , 3As shown in Figures 9 and 11, a maintenance platform 4 is fixedly provided on the front side of the lower tank 1. Two support legs are fixedly provided at the bottom of the maintenance platform 4. A front ladder is fixedly provided on the front side of the maintenance platform 4. Maintenance personnel can easily perform maintenance on the actuation component 5 by climbing to the top of the maintenance platform 4.

[0061] The inner wall of the upper tank 2 is provided with a detachable mounting bracket 10. Multiple electromagnets 14 are fixedly provided at the bottom of the mounting bracket 10. The electromagnets 14 become magnetic after being energized.

[0062] After being crushed at the jet assembly 12, the heavy metal scavenging agent particles move upward under the action of the airflow and enter the upper tank 2. During the upward movement, the heavy metal scavenging agent particles pass by the mounting frame 10. The electromagnet 14 on the mounting frame 10 has magnetic force and can attract and separate any iron particles that may be present, preventing them from being mixed in with the heavy metal scavenging agent after the crushing process. After the raw material is crushed, it moves upward under the action of the airflow. Compared with the raw material, iron particles are heavier and the airflow has difficulty blowing them upward. Therefore, the iron particles will naturally move downward and eventually fall into the collection assembly. The electromagnet 14 above is there as a precaution to prevent the iron particles from moving upward unexpectedly.

[0063] After crushing, it is necessary to separate the fully crushed particles from the uncrushed particles, such as... Figure 3 , 9 As shown in Figure 10, the upper tank 2 is provided with a separation component 3 at its top. The separation component 3 includes an upper flow channel 305 provided at the top of the upper tank 2 via a flange. The upper flow channel 305 communicates with the interior of the upper tank 2. A separation box 301 is fixedly provided at the top of the upper flow channel 305. A grading wheel 304 is provided inside the separation box 301.

[0064] The separation box 301 is fixedly provided with a top motor 303 for driving the grading wheel 304 to rotate. The separation box 301 is fixedly provided with a discharge channel 306. The front end of the grading wheel 304 is rotatably connected to the discharge channel 306. The separation box 301 is provided with a box cover 302 at the top. The box cover 302 closes the opening at the top of the separation box 301. Both ends of the box cover 302 are connected to the upper tank 2 by bolts.

[0065] The upward-moving heavy metal scavenging agent particles move upward through the upper flow channel 305 into the separation box 301. The classifying wheel 304 in the separation box 301 rotates under the drive of the top motor 303. The classifying wheel 304 can suck in the fully crushed powdered heavy metal scavenging agent and discharge the powder along the discharge channel 306 through airflow. The discharge channel 306 can be connected to equipment such as a bag filter to finally separate the air and collect the powdered heavy metal scavenging agent. The heavy metal scavenging agent that is not fully crushed cannot pass through the classifying wheel 304 and finally falls into the collection component 8 for recycling during the interval when the jet assembly 12 stops operating.
