Description

Technical Field

[0001] The invention relates to the technical field of airflow pulverizing equipment, and in particular to a heavy metal capture agent airflow pulverizing equipment. Background Art

[0002] Heavy metal scavenger is a chemical agent mainly used in the field of wastewater treatment. Adding it to wastewater can separate and remove heavy metal ions in the wastewater. Heavy metal scavengers are divided into two categories: inorganic salts and organic compounds according to their main components.

[0003] In order to facilitate mixing with wastewater, most solid heavy metal capture agents are processed into solid particles and solid powders during the production process, such as sodium sulfide, polyaluminium chloride, etc. This process requires the use of air flow pulverising equipment, such as a air flow pulveriser for producing heavy metal capture agents with publication number CN208427186U in the prior art.

[0004] The air flow pulverizing equipment in the prior art is equipped with multiple high-pressure nozzles, which eject high-pressure airflow to impact large solid particles, and at the same time, these solid particles collide with each other, thereby pulverizing the solid particles, such as a air flow pulverizer for producing heavy metal capture agents with publication number CN213762191U.

[0005] However, this crushing method has the following two problems: first, the number of nozzles is limited and their positions are fixed, and the gap between two adjacent nozzles is not covered by airflow, which makes the impact range of the high-pressure airflow insufficient; second, most of the solid particles that need to be crushed, including heavy metal scavengers, are not hard enough.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0021] The present invention provides Figure 1-14 The heavy metal capture agent air flow pulverizing device shown includes a lower tank body 1, a detachable upper tank body 2 is provided on the top of the lower tank body 1, a jet component 12 is provided inside the lower tank body 1, and a toggle component 5 for driving the jet component 12 to rotate is provided on one side of the lower tank body 1.

[0022] The jet assembly 12 includes an annular air channel 1201, a plurality of nozzles 1203 are fixedly provided on the inner side of the annular air channel 1201, a gasket 1204 in contact with the inner wall of the lower tank body 1 is fixedly provided on the outer end of the annular air channel 1201, sliding grooves 13 are provided on both sides of the lower tank body 1, the two sliding grooves 13 are symmetrical, and the gasket 1204 seals the sliding grooves 13, an extended protrusion 1202 is fixedly provided on one side of the annular air channel 1201, the extended protrusion 1202 penetrates the gasket 1204, and one end of the extended protrusion 1202 extends to the outside of the lower tank body 1 through the sliding groove 13 on the corresponding side, and the toggle assembly 5 can toggle the extended protrusion 1202, thereby driving the overall twist of the jet assembly 12.

[0023] An air inlet pipe 1205 for conveying high-pressure carbon dioxide gas is fixedly provided on the side opposite to the annular airway 1201 and the extended protrusion 1202. The air inlet pipe 1205 passes through the gasket 1204 and is connected to the inner cavity of the annular airway 1201. One end of the air inlet pipe 1205 extends to the outside of the lower tank body 1 through another sliding groove 13. A return spring 1206 is provided at the top of the air inlet pipe 1205. The top of the return spring 1206 is fixedly connected to the outer end of the lower tank body 1. A plurality of groups of positioning plates 15 are provided on the inner wall of the lower tank body 1 by bolts. The number of positioning plates 15 in each group is two. The two positioning plates 15 in the same group clamp the annular airway 1201 in the middle. Two balls 16 in contact with the annular airway 1201 are fixedly provided on the positioning plate 15 facing the side of the annular airway 1201. The annular airway 1201 can be clamped and fixed by the positioning plate 15. At the same time, the balls 16 can reduce friction to ensure smooth rotation of the annular airway 1201.

[0024] External high-pressure carbon dioxide gas is introduced into the annular airway 1201 through the air inlet pipe 1205, and finally sprayed outward through the nozzle 1203. The heavy metal capture agent that enters the lower tank body 1 falls at the central position of the inner side of the annular airway 1201, and is therefore impacted by the airflow ejected by the nozzle 1203. The heavy metal capture 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 cause the solid particles to be further broken.

[0025] During the gas crushing process, the toggle assembly 5 starts working and toggle the extension protrusion 1202. After being toggled, the extension protrusion 1202 slides along the sliding groove 13 and drives the jet assembly 12 to rotate at a certain angle as a whole. The nozzle 1203 swings left and right. During the swinging process, the direction and position of the airflow sprayed by the nozzle 1203 are constantly changing, thereby constantly adjusting the force direction of the solid particles, so that the gap between the two adjacent nozzles 1203 is also covered by the airflow, thereby increasing the coverage range and impact range of the airflow, and thus making the force on the solid particles more uniform, thereby improving the crushing effect.

[0026] In order to continuously move the jet assembly 12, Figure 4-7 As shown, the toggle assembly 5 includes a toggle motor 501 which is bolted to one side of the lower tank body 1, a toggle wheel 502 is fixedly provided at the bottom end of the output shaft of the toggle motor 501, two toggle rollers 504 are provided on the outside of the toggle wheel 502, and the two toggle rollers 504 are centrally symmetrically distributed around the center of the toggle wheel 502, and both ends of the toggle rollers 504 are rotatably connected with a clamping plate 503, and the clamping plate 503 is bolted to the outer end of the toggle wheel 502, and the toggle wheel 502 can drive the toggle rollers 504 to rotate around the center of the toggle wheel 502, and the toggle rollers 504 can contact the extended protrusion 1202 during the rotation.

[0027] When the toggle jet assembly 12 rotates, the toggle motor 501 turns on and drives the toggle wheel 502 to rotate. The toggle roller 504 installed at the outer end of the toggle wheel 502 rotates under the drive of the toggle wheel 502 and contacts the extended protrusion 1202, thereby toggling the extended protrusion 1202 to move during the rotation. The toggle roller 504 itself can rotate, thereby avoiding sliding friction during the contact with the extended protrusion 1202, reducing wear during the working process.

[0028] When the paddle roller 504 moves the outer protrusion 1202, the outer protrusion 1202 will drive the annular airway 1201 to rotate, and then drive the intake pipe 1205 to slide along another sliding groove 13. The sliding of the intake pipe 1205 causes the return spring 1206 to be stretched. As the paddle wheel 502 rotates, the paddle roller 504 will separate from the outer protrusion 1202. At this time, the elastic force of the return spring 1206 is released, pulling the 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 as a whole. The elastic coefficient of the return spring 1206 does not need to be too large, and it only needs to be able to pull the jet assembly 12 to rotate. The two paddle rollers 504 will alternately and repeatedly paddle the jet assembly 12 with the rotation of the paddle wheel 502, and the above process is repeated continuously. After actual measurement, each paddle movement is separated by 1s, and it takes 0.5s for the jet assembly 12 to reset each time it rotates.

[0029] The heavy metal capture agent is continuously transported to the lower tank 1 for crushing. Figure 1 , 2 As shown in Figures 3, 12 and 13, a feed pipe 11 is provided inside the lower tank body 1, and the feed pipe 11 is located above the jet assembly 12. The solid particles falling from the front end of the feed pipe 11 all fall to the inner center position of the annular airway 1201, and the rear end of the feed pipe 11 extends to the rear side of the lower tank body 1, and a raw material storage tank 6 and a conveying and mixing assembly 7 are provided on the rear side of the lower tank body 1.

[0030] The raw material storage tank 6 is fixedly provided with a rear ladder on both sides, and a support frame is fixedly provided at the bottom end 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, and 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 end of the raw material storage tank 6. An isolation plate 601 is fixedly provided on the inner wall of the raw material storage tank 6, and the conveying channel 702 is embedded on the isolation plate 601. The isolation plate 601 divides the interior of the raw material storage tank 6 into two storage chambers, and the two storage chambers respectively store iron particles and untreated heavy metal capture agent particles. Feeding pipes are fixedly provided on both sides of the raw material storage tank 6, and the two feeding pipes are respectively communicated with the two storage chambers, and the feeding pipes are in a closed state during the crushing process.

[0031] The two storage chambers store iron particles and untreated heavy metal capture agent particles respectively. Both particles are transported upward through the conveying channel 702, then arrive at the feed pipe 11 along the inclined tube 701, and are finally input into the lower tank body 1 through the feed pipe 11, so that the two particles are input into the lower tank body 1. Among them, the iron particles are hard in texture and will not be crushed inside the lower tank body 1 (the heavy metal capture agent particles are crushed). Instead, by doping the heavy metal capture agent particles with iron particles, various particles collide with each other under the action of airflow, and the heavy metal capture agent particles can therefore collide with the hard iron particles, thereby increasing the intensity of the collision of the heavy metal capture agent particles, so that they can be more fully broken, and the efficiency of the crushing is increased. The reason why carbon dioxide gas is used as the gas for crushing is that its role is to make the interior of the lower tank body 1 in an oxygen-free environment, avoid the collision between iron particles and generate sparks, and then avoid dust explosions caused by sparks.

[0032] The iron particles and heavy metal capture agent particles need to be mixed evenly, such as Fig.12 As shown, the top of the raw material storage tank 6 is provided with an inclined tube 701, the rear end of the inclined tube 701 is fixedly connected to the conveying channel 702, the inclined tube 701 is communicated 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, and input ports 707 are provided on both sides of the conveying channel 702, and the two input ports 707 are respectively communicated with two storage chambers. Separating the iron particles from the raw materials and then inputting them through the two input ports respectively can make the mixing ratio of the two roughly equal and more uniform; the two particles will flow during the feeding process. If the isolation plate 601 is not set to separate them, the two input ports will flow with raw materials or iron particles.

[0033] The inner wall of the conveying channel 702 is rotatably connected with a central shaft 704. A conveying motor 703 for driving the central shaft 704 to rotate is fixedly provided at the top of the conveying channel 702. A plurality of spiral blades 705 are fixedly provided at the outer end of the central shaft 704. The spiral blades 705 play a conveying role after rotating. A group of stirring rods 706 is provided between two adjacent spiral blades 705. The number of stirring rods 706 in a group is four, and the number of stirring rods 706 in each group can also be adjusted. The stirring rods 706 are fixedly provided at the outer end of the central shaft 704. The stirring rods 706 stir and mix after rotating.

[0034] In the process of conveying heavy metal capture agent particles and iron particles, since the inner bottom end of the raw material storage tank 6 is sloped, the two particles can converge to the conveying channel 702 and enter the conveying channel 702 through the input port 707. At this time, the central shaft 704 at one end of the conveying motor 703 rotates, and the spiral blade 705 at the outer end of the central shaft 704 rotates and transports the solid particles entering the conveying channel 702 upward along the conveying channel 702. In the process of the two particles moving upward, they pass through each group of stirring rods 706, which play a role in stirring and mixing, and the two particles are mixed evenly, and finally input into the lower tank body 1. The uniform mixing is conducive to the uniform crushing of the heavy metal capture agent particles.

[0035] Heavy metal capture agent particles that cannot be fully crushed need to be recovered for secondary treatment, such as Figure 1 , 8 As shown, a recovery pipe 9 with a valve is fixedly provided at the bottom end of the lower tank body 1, and the jet component 12 works intermittently. The valve on the recovery pipe 9 will only be opened during the interval when the jet component 12 stops running. A collecting component 8 is provided at the bottom end of the recovery pipe 9, and the collecting component 8 includes an outer collecting box 801 fixedly provided at the bottom end of the recovery pipe 9, and an inner collecting box 802 that can be taken out separately is provided inside the outer collecting box 801. Heavy metal capture agent particles that are not fully crushed fall downward into the inner collecting box 802, and a plurality of magnet bars 803 are fixedly provided on the inner wall of the inner collecting box 802. A sealing door is provided on one side of the outer collecting box 801 through a hinge.

[0036] The iron particles and the heavy metal capture agent particles that cannot be completely crushed will fall under the action of gravity and fall downward into the outer collection box 801 through the recovery pipe 9, and finally enter the inner collection box 802 to be collected so that they can be concentrated and crushed again. The magnet bar 803 can absorb the iron particles mixed therein under the action of magnetic force, thereby recovering the iron particles and making the iron particles reusable.

[0037] To facilitate maintenance, Figure 1 , 3 As shown in , 9 and 11, a maintenance platform 4 is fixedly provided on the front side of the lower tank body 1, two supporting legs are fixedly provided on the bottom end of the maintenance platform 4, and a front ladder is fixedly provided on the front side of the maintenance platform 4. Maintenance personnel can easily perform maintenance on the toggle assembly 5 by climbing to the top of the maintenance platform 4.

[0038] A detachable mounting frame 10 is provided on the inner wall of the upper tank body 2, and a plurality of electromagnets 14 are fixedly provided at the bottom end of the mounting frame 10. The electromagnets 14 are magnetic when energized.

[0039] The heavy metal capture agent particles after being crushed at the jet assembly 12 move upward under the action of the airflow and enter the upper tank 2. During the upward movement, the heavy metal capture agent particles pass through the mounting frame 10. The electromagnet 14 on the mounting frame 10 has magnetic force, which can adsorb and separate the iron particles that may exist therein to prevent them from being mixed in the heavy metal capture agent after the crushing work. After the raw material is crushed, it moves upward with the action of the airflow. Compared with the raw material, the iron particles are heavier, and it is difficult for the airflow to blow them upward. Therefore, the iron particles will naturally move downward and eventually fall into the collection assembly. The electromagnet 14 above is just in case to prevent the accidental situation of the iron particles moving upward.

[0040] After crushing, it is necessary to separate the fully crushed particles from the uncrushed particles, such as Figure 3 , 9 As shown in 10, a separation assembly 3 is provided at the top of the upper tank body 2, and the separation assembly 3 includes an upstream channel 305 provided at the top of the upper tank body 2 through a flange, and the upstream channel 305 is communicated with the interior of the upper tank body 2. A separation box 301 is fixedly provided at the top of the upstream channel 305, and a grading wheel 304 is provided inside the separation box 301.

[0041] A top motor 303 for driving the classification wheel 304 to rotate is fixedly provided on the rear side of the separation box 301, a discharge channel 306 is fixedly provided on the front side of the separation box 301, the front end of the classification wheel 304 is rotatably connected to the discharge channel 306, a box cover 302 is provided on the top of the separation box 301, the box cover 302 closes the opening on the top of the separation box 301, and both ends of the box cover 302 are connected to the upper tank body 2 by bolts.

[0042] The heavy metal capture agent particles moving upward move upward to the inside of the separation box 301 through the upstream channel 305, and the grading wheel 304 in the separation box 301 rotates under the drive of the top motor 303. The grading wheel 304 can suck in the fully crushed powdered heavy metal capture agent and discharge the powder along the discharge channel 306 through the airflow. The discharge channel 306 can be connected to equipment such as a bag dust collector to finally separate the air and collect the powdered heavy metal capture agent. The heavy metal capture agent that has not been fully crushed cannot pass through the grading wheel 304, and finally falls into the collection component 8 for recovery in the gap when the jet component 12 stops running.

[0043] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
